As most parts of the country gradually enter the hot summer, the northern region has finally bid farewell to the long cold winter with serious fog and haze. However, even in sunny and dry summer, air quality cannot be taken lightly. In July, the temperature in most areas will rise to more than 30 degrees. Especially in Guangdong and Guangxi, the hot summer often lasts for more than half a year. The high temperature will enhance the volatility of many organic pollutants, such as formaldehyde, benzene, radon, etc., which are the pollutants with great harm to human health. They are often hidden in building materials, such as paint, synthetic board, gypsum, etc, It is unavoidable, which is why we usually place bamboo charcoal bags in newly decorated houses. In addition, after the temperature rises, the bacteria and dust mites in the air are more active than in winter. In addition, the human body's dander, sweat evaporation, etc., the air quality is also worrying. At this time, the air purifier should be invited.
The composite filter element containing HEPA filter layer in the air purifier can effectively filter air pollutants including organic pollutants. Therefore, whether in areas with poor air or newly decorated houses, the air purifier can effectively improve the indoor air. If there are smokers or people with sensitive respiratory tract in the home, it is more necessary to clean the indoor air. Air purifier One time investment benefits the whole family Why not.
However, the traditional air purifier is placed in a fixed location, and its purification efficiency is relatively low. If it is placed in the living room, it is difficult to purify other rooms at the same time, and ordinary families usually do not buy multiple purifiers, so the mobile purification robot came into being. The Kovos Qinbao AA30 we are going to experience today is such a robot product, Let's take a look at the performance of Qinbao AA30.
Unpacking and appearance
In terms of appearance, it has continued the consistent design style of Coworth, the cylinder design with large rounded corners, and the overall shape is relatively simple.
The color matching of the fuselage is also the ivory+black mosaic design commonly used by Coworth. The simple color matching makes it quite versatile, and can coexist harmoniously with various styles of furniture.
The top cover of the fuselage is black, the middle part is a black air outlet net cover, and the inner dust cover is made of metal.
A hidden display screen is integrated on the top of the fuselage, which can display PM2.5, working mode, WiFi status, etc. It can be operated by touch, such as short press for in situ purification, long press for mobile purification. A circle of light band is not only an atmosphere lamp, but also represents the air pollution index. Users can intuitively understand the air quality of the current environment through the color of the light band.
The pollution index corresponding to the specific color is as follows:
Blue - excellent, PM2.5 0-35
Green - good, PM2.5 36-75
Orange - moderately polluted, PM2.5 76-115
Red - pollution, PM2.5 above 116
The front of the fuselage is covered with various sensors. The five holes on the fuselage are infrared distance sensors, and the black part at the bottom is equipped with ultrasonic obstacle avoidance sensors.
Several ultrasonic obstacle avoidance sensors are set in the black part of the lower part of the fuselage to judge the distance from the object through ultrasonic distance measurement. In addition to the ultrasonic obstacle avoidance sensor, the infrared sensor is also hidden. The metal charging contact is also located in this part. After Qinbao purification, it goes back to the charging base and aligns with the charging electrode piece to start automatic charging.
The sensor in the figure is the charging seat signal sensor. The whole body is equipped with nearly 40 sensors of different types, which is different from other purifiers. The rich sensors also reflect its robot properties.
There are also two spring contacts on the charging base, which can start charging after contacting the body. The fuselage is equipped with 6000mAh lithium battery. Under the maximum air volume mode, a single charge can provide about 70 minutes of use time for Qinbao AA30 and purify about 200 m2 of building area.
The back side of the charging base is equipped with a transformer and a wire material storage device to facilitate the user to sort out the wire materials and not be bothered by messy wire materials.
The two sides of the machine body are detachable filters, and the fan body can be seen after opening the filter screen. The reason why Qinbao AA30 has a filter screen on both sides is that it uses twin turbocharged air guide, which can inhale air on both sides at the same time. The air intake is larger and the filtering is faster.
Kovos has adopted a quadruple filter element including H13 HEPA filter layer. In addition to HEPA filter layer, it also includes primary filter layer, bacteriostatic filter layer and activated carbon filter layer.
The protruding part of the fuselage is the LSD laser ranging sensor. This is also the core part of Coworth when drawing an indoor map, which can scan an area of about 200 m2 at one time.
In addition to being able to control through the mobile phone APP, a remote control is also included. Most functions can be achieved through the remote control, but some operations are divided into short press/long press, which requires a certain familiarity time to get started.
Use experience and APP use
In terms of supporting APP, the smart home APP of Covos is still used, which is simple to use and low in cost. It is basically similar to other products of Covos, and can be used after simple binding.
In terms of functions, most of them are operated through APP, such as purification point setting, regular opening, air volume regulation, etc. The APP UI is simple and durable. Qinbao AA30 has three operation modes: automatic mobile purification, in situ purification and map point selection purification. Users can choose freely according to their own needs.
Compared with traditional air purifiers, Qinbao can remotely understand Qinbao's working status and air quality at home through APP. When the air in the home is poor, users can remotely control Qinbao for purification through APP.
In the APP, multiple automatic purification periods can also be set by appointment. For example, when users return home at about 7:30 every day, they can book automatic mobile purification or fixed point purification at 6:30. When users return home, they can open the door to welcome fresh air, which is also impossible for traditional air purifiers.
After starting drawing construction, Qinbao AA30 purification robot in motion.
Multiple sensors work together, and Qinbao AA30 will automatically turn to avoid obstacles in front.
In addition to the in situ purification mode, other modes will first build maps. After the map is automatically started, each room and various furniture will be scanned and modeled through the collaborative work of various sensors, and the size, obstacles, air quality, etc. of each room will be measured. Finally, the indoor map will be obtained, and then the reasonable purification path will be calculated according to the SLAM algorithm of Coworth, Then Qinbao will start intelligent mobile purification.
After completing the map building, Qinbao will move and purify independently, and Qinbao will automatically dodge when encountering obstacles.
When the battery is low, Qinbao AA30 will automatically return to the charging base for charging.
The remote control purification mode controls Qinbao's movement through the remote controller to realize the fixed-point purification operation.
In terms of automatic purification, Qinbao AA30 is quite easy to use. From automatic map building to automatic obstacle avoidance movement, Qinbao can independently complete the obstacle avoidance function. The availability of obstacle avoidance function is very high. It is rarely stuck or unable to return to the charging position, and it is more intelligent than many sweeping robots.
In actual use, users can use mobile purification. If they are afraid of interruptions, they can also reserve purification time according to their own needs. When they do not want to take out their mobile phones, they can also use the remote control to operate, which can be said to be very easy to use.
Purification effect and noise
Whether as a purifier or a purification robot, its core competitiveness is obviously the air purification effect, which is also the foundation of an air purifier.
Obviously, objective data can best reflect the purification effect, among which CADR and CCM parameters are more important, which are also important indicators directly related to the quality of filter element.
Demonstration of automatic purification mode
In terms of CADR, Qinbao AA30 can provide 600m ³/h particulate matter purification and 300m ³/h formaldehyde purification index. In terms of CCM, the particulate matter test and formaldehyde test are 32225mg and 6500mg respectively. This parameter can meet the needs of most users. There is no pressure to deal with a 70 square meter room. In addition to the mobile purification function, it can effectively expand the purification area and purify the whole room.
Test conditions
We used cigarettes to pollute the indoor air, and the measured PM2.5 was about 400 (usually 40-50 in daily life). Then we used Qinbao AA30 to test, and used a strong gear for purification. After about 10 minutes, PM2.5 dropped to about 40, and the purification speed was quite fast. This may be due to the double turbine technology of Covance. Air is sucked into both sides of the fuselage at the same time. Compared with many purifier products with unilateral air intake, the filtration efficiency is higher. There is no need to worry too much about the purification effect.
Red - monitoring point A blue - monitoring point B yellow - pollution source
In addition, we also conducted purification efficiency test for mobile purification. We set two purification points in the room, namely, monitoring point A near the pollution end and monitoring point B near the fixed purification position.
Left - monitoring point 1 right - monitoring point 2
Light two cigarettes at the same time, and after PM2.5 reaches the same concentration, purify them in situ and mobile evolution mode for 5 minutes respectively, and then read the two monitored readings for comparison.
Environmental objective reading
Contaminated test environment readings
fixed point Before purification test
move Before purification test
Test environment reading after purification
fixed point After purification test
move After purification test
Through this test, we can see the difference between the two purification modes. Similarly, after 5 minutes of purification, the reading of monitoring point A is close, but the reading of mobile purification mode is slightly lower, but the reading of monitoring point B is quite different. The reading of mobile purification mode is significantly lower, which also means that mobile purification has higher purification efficiency than fixed point purification.
This test is also proving the advantages of mobile purification over traditional purification. The traditional fixed-point purification area is limited, and the air in different rooms is completely replaced by convection. It is often easy to see that the air in the room where the purifier is located has been repeatedly filtered, while the air in other rooms has not been purified, and the purification efficiency is relatively low. Qinbao purifies by moving itself rather than air convection. The air interaction speed is faster and the purification efficiency is higher, which is the biggest significance of the mobile air purification robot.
In terms of noise test, the mute level, standard level and strong level are 42 dB, 54 dB and 65 dB respectively. The noise control is relatively reasonable, especially the mute level, which basically does not affect sleep.
summary
As the latest masterpiece of Kovos in the field of purification robots, Qinbao AA30 integrates the scientific and technological achievements of Kovos in the field of intelligent robots. Although the property of Qinbao AA30 is air purifier in terms of functionality, it integrates the functions of many machine talents, such as LDS laser scanning, infrared ranging, ultrasonic obstacle avoidance sensor, downward looking fall prevention sensor, etc, Now, Kovos has integrated it into the air purifier and made it move intelligently. What used to need multiple machines can be done by one. Maybe this is the change that technology has brought to our lives.
As a pure purifier, Qinbao AA30 has excellent hardware parameters. With a particle purification index of 600m ³/h and a formaldehyde purification index of 300m ³/h, there is no pressure to deal with medium and large rooms with normal area. The addition of mobile purification further enhances the purification capacity.
However, Qinbao does not simply move at the purification point, but adds a laser dust sensor to measure the number of air particles at different locations in different rooms through the laser dust sensing system, calculates the most reasonable purification path in combination with SLAM algorithm, and focuses on the purification of heavily polluted locations. Compared with traditional fixed purifiers, Mobile purification can not only further increase the purification area, but also maximize the purification efficiency of a single purifier. In contrast, Qinbao AA30 is more suitable for relatively large houses, which can quickly clean the whole house. The price of the air purifier is almost the same as that of the air purifier with the same CADR value on the market. It is a worthy air purification robot.
