[0040] The present utility model provides a display box.

[0041] Referring to Figures 1 to 3 , in one embodiment, the display box includes:

[0042] A box body 100, in which a display board 300 is provided. The display board 300 has a first area 310 and a second area 320 connected to the first area 310. A protective layer is provided in the first area 310, and the second area 320 is used to arrange a sensor assembly 400.

[0043] A cover body 200, in which a partition member 210 is provided; the cover body 200 is detachably connected to the box body 100, and when the cover body 200 is closed with the box body 100, the partition member 210 abuts against the second area 320 of the display board 300 and the side wall of the box body 100 to form a receiving cavity, so as to separate the sensor assembly 400 from the first area 310.

[0044] In this embodiment, in the first area 310, there are electronic control devices other than the sensor assembly 400, and a protective layer is provided for these electronic control devices by applying three-proof glue, spraying anti-static paint, anti-corrosion paint, etc. The shape of the second area 320 is adaptively modified according to the shape of the partition member 210, so as to avoid the protective layer in the first area 310 being framed into the receiving cavity due to the irregular shape of the second area 320.

[0045] Specifically, after the box body 100 and the cover body 200 are combined, the partition member 210 abuts against the side wall of the box body 100, and since the height of the partition member 210 is higher than the height of the side wall of the box body 100. Therefore, when the box body 100 and the cover body 200 are closed, the partition member 210 extends into the box body 100 and abuts against the surface of the control board, so that the partition member 210, the box body 100 and the control board form a partition area, physically isolating the first area 310 and the protective layer provided on its surface. It should be noted that the sensor assembly 400 is integrated on the display board 300 and is electrically connected to the display board 300 through the wiring layer of the display board 300. Therefore, there is no need to provide through holes in the partition member 210, ensuring the airtightness of the partition member 210. Thus, the first area 310 is completely separated from the sensor assembly 400, avoiding the strong smell of the newly molded plastic glue parts caused by brushing three-proof paint or applying glue to the display board 300, so that the sensor is affected by the smell and the read data is incorrect and cannot accurately display the corresponding value.

[0046] The technical solution of the present utility model sets the first area 310 and the second area 320 in the display board 300 to partition the sensor assembly 400 and the protective layer of the display board 300; and a partition member 210 is provided in the cover body 200, so that when the cover body 200 is closed with the box body 100, the sensor assembly 400 on the display board 300 can be separated from the first area 310 by the partition member 210. Since a protective layer is provided in the first area 310, after the partition member 210 separates the first area 310 from the sensor assembly 400, it can avoid the sensor being affected by the smell of brushing three-proof paint or applying glue to the display board 300, resulting in incorrect read data and unable to accurately display the corresponding value, thereby reducing the interference of external factors and improving the accuracy of the sensor reading value.

[0047] It can be understood that since the sensor assembly 400 is integrated on the display board 300, and the display board 300 is disposed within the box body 100 and the cover body 200, therefore, in order for the sensor assembly 400 to collect the gas in the environment, an air inlet 110 is provided on the side wall of the box body 100 within the accommodation cavity. In this embodiment, the air inlet 110 is located on the side wall of the accommodation cavity to introduce fresh air from the external environment. The position and size of the air inlet 110 can be adjusted according to specific requirements. In one embodiment, the air inlet 110 is in a grid shape. The grid-shaped air inlet 110 provides sufficient ventilation to ensure that the sensor assembly 400 can collect the gas in the environment through the air inlet 110.

[0048] In another embodiment, the air inlet 110 is in a mesh shape; the air inlet 110 is designed in a grid shape or a mesh shape to prevent dust, particles and other impurities from entering the accommodation cavity, and can also prevent accidental contact with the sensitive components inside the accommodation cavity, improving safety.

[0049] Specifically, the grid shape or mesh shape design can be set according to the material of the cover body 200, and metal grids, plastic grids or other appropriate materials can also be used.

[0050] Refer to Figures 1 to 3 , in one embodiment, a sealing member is provided on the side of the partition member 210 close to the box body 100.

[0051] In this embodiment, the material of the sealing member can be rubber, PU, PTFE, etc. When the cover body 200 is closed with the box body 100, the sealing member abuts against the display board 300 in the box body 100, thereby sealing the first region 310 outside the sensor assembly 400 to avoid the smell of the protective layer affecting the accuracy of the sensor assembly 400.

[0052] Refer to Figures 1 to 3 , in one embodiment, a buckle 120 is further provided on the side wall of the box body 100, and a slot 220 adapted to the buckle 120 is provided in the cover body 200.

[0053] In this embodiment, the buckle 120 can be a protruding structure to match the slot 220 of the cover body 200.

[0054] The buckle 120 of the box body 100 and the slot 220 of the cover body 200 are adapted, so that the box body 100 and the cover body 200 can be connected through simple insertion and rotation operations. The design of the buckle 120 and the slot 220 can achieve convenient connection and disassembly operations, and ensure the firmness and sealing of the connection. The structures of the box body 100 and the cover body 200 can also include other features, such as sealing gaskets, handles, etc., to further improve the sealing and convenience of the connection.

[0056] A detection circuit 410, configured to detect the air in the environment where the display box is located and output a corresponding detection communication signal;

[0057] A communication control circuit 420, connected in series between the output terminal of the detection circuit 410 and the display board 300. The communication control circuit 420 is configured to connect / disconnect the communication loop between the detection circuit 410 and the display board 300 under the control of the display board 300.

[0058] In this embodiment, I2C communication, SPI communication, etc. can be adopted between the detection circuit 410 and the display board 300.

[0071] The first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 are all pull-up resistors. The first resistor R1 is used to pull up the receive selection pin to a high level to select the valid level of the sensor chip U1; the second resistor R2 and the third resistor R3 are used to pull up the first communication pin and the synchronous clock pin to a high level when the communication control circuit 420 disconnects the communication loop between the detection circuit 410 and the display board 300.

At this time, between the display board 300 and the sensor chip U1, according to the clock signal transmitted by the always synchronous pin, the detection communication signal is transmitted through the first communication pin.

[0073] When the display board 300 does not need to detect the gas in the environment, it outputs a corresponding control signal to the communication control circuit 420, that is, outputs a low level to the first switching transistor Q1 and the second switching transistor Q2, controls the first switching transistor Q1 and the second switching transistor Q2 to turn off, so as to disconnect the communication with the sensor chip U1.

[0075] A power supply circuit 430, the input end of the power supply circuit 430 is used to connect to the first power supply, the output end of the power supply circuit 430 is connected to the power supply end of the detection circuit 410, and the power supply circuit 430 is further used to perform electrical conversion processing on the connected power supply and supply power to the detection circuit 410.
