preface

First of all, I should apologize to Suzhou FLECH Intelligent Technology Co., Ltd. and Lei Feng for their trial. They have been delaying the submission of the report due to personal reasons. Even if the report is badly written, they should submit the report according to the specified time. This is my fault.

First, let's talk about the new oxygen air purifier I got. The first time I received it was supposed to be the white model. For some reasons, my customer service sister readily agreed to replace the blue model in her hands.

Unpacking

The new oxygen air purifier includes: host, power connection line, operation manual and certificate of conformity.

Take off the upper protective foam, and the first thing you see is the 7-inch touch screen. It can be seen from the appearance that the air outlet is designed at the top of the fuselage, and the air inlet is designed at the lower front of the fuselage. On the left and right sides of the host, there are sensors and side doors; The back of the machine body is the product nameplate and power socket.

The whole design is square, very simple and clear. There is only one screen opening/closing button on the body, and the rest of the operations are completely completed through the 7-inch touch screen. Of course, it can also be controlled wirelessly through APP.

Disassembly

When the power supply is not connected, the author is very curious about the structure, so you know. Remove 4 screws at the top and bottom to separate the front and rear.

The internal structure is very simple. From top to bottom, there are HEPA high-efficiency filter screen (white), activated carbon filter screen (white back, double-layer bonded together), catalytic light source, nano catalytic screen, and air duct system.

The circuit of the new oxygen is very clear. Even if Xiaobai looks at it, he can understand everything. Most of the sockets are plug-in connectors. Even if you need to replace the original in the future, you can do it yourself. The lines are marked so that there is no mistake.

You may find that when you open the side door, you cannot start the machine. This is because the side door controls two microswitches. The microswitch will be closed only when the side door is closed, so that you can start the machine normally. If your machine cannot start, it is probably the microswitch. Simply adjust the position of the side door and the microswitch.

Take off the filter screen and catalytic light source, you can clearly see the air duct system, which is the power system of this purifier. The air inlet and outlet are all dependent on this air duct system.

Next, let's talk about the "lung" of the purifier. The whole lung consists of a multi-layer filter screen and a layer of catalytic light source, which purifies the inhaled air through multiple layers before exhaling.

Start up

Power on is very simple. For the first time, just connect the power supply and wait for a few seconds. The 7-inch touch screen has a good touch and can accurately operate the above options.

It can be seen from the comparison with the official test data that the difference between the values is very small, which indicates that the real-time data of the new oxygen purifier is very reliable.

APP

The APP operation is very simple, and the machine can be remotely controlled by simple operation. In the mobile phone application, you can view the real-time air quality, filter usage, and adjust the status of the purifier.
