DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] See also Figure 1-Figure 2 The present application provides an air quality detection device, which includes a housing 2, a bracket assembly 24 and a plurality of detection units.

[0042] Multiple groups of ventilation holes 3 are opened on the shell 2, and the bracket assembly 24 is installed in the shell 2. Multiple independent detection cavities are formed between the bracket assembly 24 and the shell 2. The multiple detection cavities correspond one-to-one to the multiple groups of ventilation holes 3. The ventilation holes 3 are connected to the corresponding detection cavities. Multiple detection units correspond one-to-one to the multiple detection cavities. The detection units are located in the detection cavities and are used to detect air components.

[0043] The air enters the corresponding detection cavity through the vent 3, and the detection unit in the detection cavity can detect the components of the air. Since the detection device integrates multiple detection units, each detection unit can detect at least one air component, so the detection unit can detect multiple components of the air at the same time. Since the detection cavities of the multiple detection units are independent of each other, the detection of the air components by the multiple detection units does not affect each other. In this way, multiple components of the air can be detected more quickly and accurately, so that the detection device has multiple detection functions.

[0044] Based on the above design, this embodiment can independently detect multiple air components at the same time by installing multiple detection units in multiple independent detection cavities, thereby increasing the function of the detection device to detect air components and further improving the detection effect of the detection device.

[0045] In some embodiments, see Figure 2-Figure 4 The bracket assembly 24 includes a mounting frame 6 and a sealing plate group 7, a first detection cavity 9 is formed between the mounting frame 6 and the outer shell 2, and a second detection cavity 8 is formed between the sealing plate group 7 and the outer shell 2; the multiple detection units include a first detection unit 10 and a second detection unit 12, the first detection unit 10 is installed in the first detection cavity 9, and the second detection unit 12 is installed in the second detection cavity 8.

[0046] The mounting frame 6 and the housing 2 can be fixed by screws. The first detection unit 10 and the second detection unit 12 are both conventional detection sensors. The working principles and circuit connections of the first detection unit 10 and the second detection unit 12 are known to those skilled in the art. For example, the first detection unit 10 can have built-in functions such as temperature and humidity detection, PM2.5 detection, formaldehyde detection, and pollen detection, and the second detection unit 12 can include CO 2 Sensors, etc.

[0047] The mounting frame 6, the sealing plate assembly 7 and the housing 2 can more easily form a first detection chamber 9 and a second detection chamber 8 that are independent of each other, thereby making it easier to provide independent detection spaces for the first detection unit 10 and the second detection unit 12.

[0048] In some embodiments, see Figure 5The plurality of ventilation holes 3 include a first ventilation hole 32 and a second ventilation hole 31 which are arranged opposite to each other. The first ventilation hole 32 includes an air inlet hole 321 and an air outlet hole 322 which are connected to each other. The first ventilation hole 32 is connected to the first detection cavity 9, and the second ventilation hole 31 is connected to the second detection cavity 8.

[0049] The ventilation method corresponding to the first detection chamber 9 is dual-channel, and the air inlet 321 and the air outlet 322 are separately arranged. The number of the air inlet 321 and the air outlet 322 can be multiple. The air enters the first detection chamber 9 from the air inlet 321 and is detected by the first detection unit 10. The air passes through the first detection chamber 9 and then goes out from the air outlet 322.

[0050] The ventilation mode corresponding to the second detection cavity 8 is a single channel. The air enters the second detection cavity 8 through the second ventilation hole 31 and is detected by the second detection unit 12 , and then can flow out from other gaps of the housing 2 .

[0051] The first vent hole 32 corresponding to the first detection unit 10 and the second vent hole 31 corresponding to the second detection unit 12 are respectively arranged on opposite side surfaces of the housing 2. In this way, the air passing through the first vent hole 32 and the second vent hole 31 do not affect each other, thereby improving the accuracy of independent detection of the first detection unit 10 and the second detection unit 12.

[0052] In some embodiments, see Figure 6-Figure 7 The mounting frame 6 includes a mounting frame 63 and an air inlet cylinder 62 and an air outlet cylinder 61 connected to the mounting frame 63. The mounting frame 63 is provided with a mounting groove 631, and the first detection unit 10 is installed in the mounting groove 631; the air inlet hole 321 is connected to the mounting groove 631 through the air inlet cylinder 62, and the air outlet hole 322 is connected to the mounting groove 631 through the air outlet cylinder 61.

[0053] The air inlet 62 and the air outlet 61 can be integrally formed with the mounting frame 63, and the air inlet 62 and the air outlet 61 can be designed as a horn structure. The air enters the air inlet 62 from the air inlet hole 321 on the housing 2, and then enters the mounting groove 631 from the air inlet 62. After being detected by the first detection unit 10, the air enters the air outlet 61, and then flows out from the air outlet 61 through the air outlet hole 322 on the housing 2. In this way, the air can enter the first detection cavity 9 more easily through the air inlet 62, and the air can flow out of the first detection cavity 9 more easily through the air outlet 61.

[0054] In some embodiments, please refer again to Figure 7 A plurality of buckles 14 are provided on the side wall of the mounting groove 631 , and the buckles 14 are in contact with the top surface of the first detection unit 10 .

[0055] The buckle 14 can be integrally formed with the mounting frame 63, and the material of the buckle 14 has a certain elasticity, for example, it can be a rubber material, etc. When the first detection unit 10 is installed in the mounting groove 631, the plurality of buckles 14 are located above the first detection unit 10 and contact the top surface of the first detection unit 10, thereby limiting the first detection unit 10, so that the first detection unit 10 can be stably installed in the mounting groove 631.

[0056] In some embodiments, please refer again to Figure 7 A plurality of limiting protrusions 13 are provided on the side wall of the mounting groove 631 , and the limiting protrusions 13 are in contact with the side surface of the first detection unit 10 .

[0057] The limiting protrusion 13 can be integrally formed with the installation frame 63, and the material of the limiting protrusion 13 has a certain elasticity, for example, it can be a rubber material, etc. After the first detection unit 10 is installed in the installation groove 631, the plurality of limiting protrusions 13 are located on the side of the first detection unit 10 and contact the side of the first detection unit 10, so as to limit the first detection unit 10, so that the first detection unit 10 can be more stably installed in the installation groove 631.

[0058] In some embodiments, see Figure 7-Figure 8 A first sealing gasket 15 is provided between the air inlet cylinder 62 , the air outlet cylinder 61 and the housing 2 ; a second sealing gasket 16 is provided between the air inlet cylinder 62 , the air outlet cylinder 61 and the first detection unit 10 .

[0059] Both the first sealing gasket 15 and the second sealing gasket 16 can be isolation foams. The first sealing gasket 15 can increase the sealing between the air inlet cylinder 62, the air outlet cylinder 61 and the outer shell 2, and the second sealing gasket 16 can increase the sealing between the air inlet cylinder 62, the air outlet cylinder 61 and the first detection unit 10, thereby preventing the gas in the air inlet cylinder 62 and the gas in the air outlet cylinder 61 from interfering with each other, thereby improving the detection accuracy of the gas by the first detection unit 10.

[0060] In some embodiments, please refer again to Figure 2 and Figure 8 The sealing plate group 7 includes a sealing seat 73, a first sealing plate 71 and a second sealing plate 72. The sealing seat 73 and the first sealing plate 71 are both installed in the outer shell 2. The second sealing plate 72 is connected to the sealing seat 73. A first detection cavity 9 is formed between the sealing seat 73, the first sealing plate 71, the second sealing plate 72 and the outer shell 2. A card slot 17 is also provided in the outer shell 2, and at least part of the first sealing plate 71 is clamped in the card slot 17.

[0061] The card slot 17 is arranged in the cavity of the housing 2, and the first sealing plate 71 can be more conveniently and stably installed on the housing 2 through the card slot 17, and the second sealing plate 72 can be fixed to the sealing seat 73 by screws. In this way, the sealing performance of the first detection cavity 9 formed by the sealing seat 73, the first sealing plate 71, the second sealing plate 72 and the housing 2 is better, so that the mutual influence between the first detection cavity 9 and the second detection cavity 8 can be reduced, and then the detection accuracy of the second detection unit 12 can be improved.

[0062] In some embodiments, please refer again to Figure 4 The housing 2 is provided with an oblique rib 11 . When the mounting frame 6 is installed in the housing 2 , the mounting frame 6 contacts the oblique rib 11 and moves toward the direction of the corresponding vent hole 3 .

[0063] The length of the oblique rib 11 extending toward the first air vent 32 gradually decreases from bottom to top. When the mounting bracket 6 is locked in the outer shell 2 by screws, the mounting bracket 6 will contact the oblique rib 11. As the mounting bracket 6 moves toward the bottom surface of the outer shell 2, the mounting bracket 6 will move toward the first air vent 32 under the action of the oblique rib 11, and finally the air inlet pipe 62 and the air outlet pipe 61 are pressed against the outer shell 2, and a pre-tightening force is applied to the first sealing gasket 15 between the air inlet pipe 62, the air outlet pipe 61 and the outer shell 2, thereby further improving the sealing between the air inlet pipe 62 and the air outlet pipe 61 and the outer shell 2.

[0064] In some embodiments, see Fig. 9 The detection device also includes a power box 1 installed on the shell 2, and an installation cavity 101 is opened on the power box 1. The detection device also includes a battery 20 installed in the installation cavity 101 and a spring 18 in contact with the battery 20; a limit buckle 19 is provided on the side wall of the installation cavity 101, and at least part of the spring 18 is clamped on the limit buckle 19.

[0065] The power box 1 includes a back cover, which covers the battery 20 to protect the battery 20. The spring 18 can be electrically connected to the battery 20. The spring 18 is installed on the limit buckle 19 on the outer shell 2, so that the spring 18 can be more stably installed on the outer shell 2, thereby improving the performance of the detection device.

[0066] Preferably, see Fig. 9 and Fig.10 The housing 2 is also provided with a built-in slot 21, in which an adapter 23 is provided. The adapter 23 can power the electrical components of the detection device, such as the first detection unit 10, the second detection unit 12, etc. When the adapter 23 and the battery 20 are used at the same time, the power of the battery 20 will not be consumed, so that the power of the battery 20 can be saved.

[0067] Preferably, see Fig. 9and Fig.10 The housing 2 has a limit plate 22, and the adapter 23 is mounted on the limit plate 22. The limit plate 22 can prevent the device from being damaged when the user plugs in or unplugs the charging cable.

[0068] Preferably, see again Figure 1 A display screen 5 is also provided on the housing 2, and the display screen 5 can be electrically connected to the battery 20 and / or the adapter 23. Dust-proof foam can also be provided between the display screen 5 and the housing 2 to prevent the display screen 5 from being contaminated by dust. The data of the air detection by the detection device can be observed through the display screen 5, thereby providing a better experience for the user.

[0069] Preferably, see again Figure 1 A button 4 is also provided on the shell 2, and the detection device can be connected to the APP on the terminal through the button 4. When the detected solubility exceeds the threshold set by the user, it will be automatically reported to the user, so that human-computer interaction can be realized, so that the user can more conveniently remotely observe the detection status of the detection device on the air.

[0070] The above are only various implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
