Description

Technical Field

[0001] This utility model belongs to the field of air quality detection technology, and in particular relates to an indoor air quality detection device. Background Technology

[0002] Indoor air quality testing primarily targets and analyzes substances in the indoor environment that may affect health and comfort, including particulate matter (such as PM2.5 and PM10), harmful gases (such as CO2, CO, formaldehyde, and VOCs), temperature and humidity, and microorganisms (such as mold and bacteria). Indoor air quality testing is an important means of ensuring health and comfort and is applicable to various scenarios such as homes, offices, and public places.

[0003] Currently, there are some devices available on the market for indoor air quality testing. For example, an indoor air quality detector with publication number CN213933751U is disclosed on the China Patent website. This air quality detector can be used for indoor air quality testing, but it has some defects and shortcomings that need to be improved: (1) Due to structural design reasons, the sampling range of a single air quality testing device is relatively limited, making it difficult to cover the entire indoor space, resulting in inaccurate test data; (2) After working for a long time, the surface of some existing air quality testing devices often generates a lot of heat, and the traditional natural cooling method is inefficient and difficult to quickly reduce the surface temperature of the testing device, which can easily lead to the testing device malfunctioning due to prolonged overheating. Therefore, in view of the above problems, the indoor air quality testing device provided by this utility model is of great significance. Utility Model Content

[0004] This invention provides an indoor air quality detection device. Through multiple detection components, air quality detectors can achieve distributed detection, allowing simultaneous air quality monitoring at multiple locations within the room. This effectively expands the sampling range of the device, enabling it to cover the entire indoor space and thus improving the accuracy of the detection data. The thermal grease on the top of each heat-conducting plate fully absorbs the surface heat of the air quality detector and transfers it to the heat-conducting plate. Multiple heat dissipation vents quickly diffuse the heat to the surrounding area, achieving a rapid cooling effect and preventing the air quality detector from malfunctioning due to prolonged overheating. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0033] Please see Figure 1-9 As shown, an indoor air quality testing device of this utility model includes a base 1, a plurality of anti-wear pads 2 are provided on the bottom surface of the base 1, and a rotating seat 3 is provided at the bottom of the base 1. The rotating seat 3 is circular and has a lifting mechanism on its top. Supports 4 are provided on both sides of the rotating seat 3. The supports 4 are fixedly connected to the base 1, and handles 5 are fixedly connected to the side walls of the supports 4. By holding the handles 5, the base 1 and the entire testing device can be lifted upward together, so as to move and transport the testing device.

[0034] The lifting mechanism includes a cylinder 6, which is mounted on the top of the rotating seat 3. A lifting plate 7 is fixedly connected to the top of its output shaft. The lifting plate 7 is circular, and several adjusting seats 8 are fixedly connected to its top. Each adjusting seat 8 has an adjusting cavity 9 inside, and a detection component is installed in the adjusting cavity 9. By driving the cylinder 6, the lifting plate 7 and each detection component can be moved up and down together, so as to adjust the detection height of each detection component as needed.

[0035] The detection component includes a connecting block 10, with a detection frame 11 fixedly connected to the end of the connecting block 10. The bottom of the detection frame 11 has several heat dissipation vents 12 and several heat-conducting plates 13. An air quality detector 14 is installed on the detection frame 11. The air quality detector 14 can be an existing product on the market, such as the AES-90 air quality detector. The air quality detector 14 integrates a gas sensor, a main control chip, a display screen, and a communication module. It can monitor the concentration of harmful gases such as PM2.5, formaldehyde, and benzene in indoor air in real time and display the information on the display screen for easy viewing.

[0036] The base 1 is circular, and a limiting groove 15 is formed on its top surface. The limiting groove 15 is an annular groove structure. A pair of protrusions 16 are fixedly connected to the bottom of the rotating seat 3. The cross-section of the protrusions 16 is circular, and its diameter is equal to the width of the limiting groove 15. The bottom end of each protrusion 16 extends into the limiting groove 15 and fits against the groove wall of the limiting groove 15. The rotating seat 3 can drive the lifting mechanism to rotate together with each detection component so as to adjust the detection angle of each detection component as needed. When the rotating seat 3 rotates, it can drive the protrusions 16 to rotate around the limiting groove 15. At this time, the mutual cooperation between the protrusions 16 and the limiting groove 15 can play a limiting and guiding role to improve the stability of the rotating seat 3 and prevent it from deviating and shaking during rotation.

[0037] The bracket 4 is equipped with a positioning mechanism, which includes an electric telescopic rod 17. The electric telescopic rod 17 is installed on the side wall of the bracket 4, and a positioning plate 18 is fixedly connected to the end of its output shaft. The positioning plate 18 is arc-shaped, and its diameter corresponds to the diameter of the rotating seat 3. The inner surface of the arc-shaped positioning plate 18 is provided with an anti-slip pad 19. The surface of the anti-slip pad 19 is engraved with herringbone anti-slip patterns. The anti-slip pad 19 can be made of elastic materials such as rubber and is fixed by means of glue. After the angle adjustment of the detection component is completed, the electric telescopic rod 17 can be driven to move the positioning plate 18 until the positioning plate 18 is tightly attached to the side wall of the rotating seat 3. At this time, the anti-slip pattern on the surface of the anti-slip pad 19 can increase the friction between the rotating seat 3 and the positioning plate 18, so as to fix the angle of the rotating seat 3 and prevent it from deflecting during the detection process.

[0038] The cylinder 6 has several first mounting seats 20 fixedly connected to its bottom end. Each first mounting seat 20 has a first mounting hole 21. A bolt 22 is inserted into the first mounting hole 21. The top surface of the rotating seat 3 has several threaded grooves 23 that mate with the bolts 22. The number of threaded grooves 23 is the same as that of the first mounting seats 20. Their diameters correspond to the diameters of the first mounting holes 21. The center of each threaded groove 23 corresponds to the center of each first mounting hole 21. By tightening the bolts 22 in each first mounting hole 21, the bolts can be screwed into the corresponding threaded grooves 23. At this time, the lifting mechanism can be fixedly installed on the top of the rotating seat 3 through the mutual cooperation between the bolts 22 and the threaded grooves 23. By unscrewing the bolts 22, the entire lifting mechanism can be removed from the rotating seat 3 for maintenance and replacement of related components.

[0039] Both the connecting block 10 and the adjusting cavity 9 are rectangular, and the width and thickness of the connecting block 10 are equal to the width and height of the adjusting cavity 9, respectively. The adjusting seats 8 are distributed in an equidistant ring along the circumference of the lifting plate 7, and each adjusting seat 8 has an adjusting groove 24 on its top. The adjusting groove 24 is rectangular. A first stud 25 is fixedly connected to the top of the connecting block 10. The diameter of the first stud 25 is equal to the width of the adjusting groove 24, and the first stud 25 passes through the corresponding adjusting groove 24 and is threadedly connected to a first nut 26 that mates with it. The connecting block 10 can drive the detection frame 11. Together with the air detector 14, it moves along the inner wall of the adjustment cavity 9 to extend the length of the connecting block 10, thereby expanding the detection range of each air detector 14 as needed. The extension length of the connecting block 10 can be fixed by tightening the first nut 26 on the first stud 25. At the same time, distributed detection can be achieved through the air detectors 14 in the multiple detection components, so as to simultaneously detect the air quality at multiple locations in the room, thereby effectively expanding the sampling range of the detection device to cover the entire indoor space and thus improving the accuracy of the detection data.

[0040] The top of both sides of the testing frame 11 is L-shaped and fixedly connected with several second studs 27. Each second stud 27 is threaded with a corresponding second nut 28. The side wall of the air detector 14 is fixedly connected with several second mounting seats 29, the number of which is the same as the number of second studs 27. Each second mounting seat 29 has a second mounting hole 30, the diameter of which corresponds to the diameter of the second stud 27. The center of each second mounting hole 30 corresponds one-to-one with the center of each second stud 27. Each second stud 27 can be aligned and passed through its corresponding second mounting hole 30. The second nut 28 is then threaded onto each second stud 27 and tightened. The air detector 14 is fixedly mounted on the corresponding testing frame 11 through the cooperation of the second studs 27, second mounting holes 30, and second nuts 28. When the air detector 14 malfunctions, it can be removed from the testing frame 11 by unscrewing the second nut 28 for replacement.

[0041] The heat-conducting plates 13 are linearly distributed at equal intervals along the width of the testing frame 11, and the top surface of each heat-conducting plate 13 is coated with thermal grease. The heat dissipation vents 12 are rectangular, and each heat dissipation vent 12 is located between two adjacent heat-conducting plates 13. The heat-conducting plates 13 can be made of metal materials with strong thermal conductivity, such as copper sheets, and are fixed by welding or other methods. When the air detector 14 is installed on the corresponding testing frame 11, the top of each heat-conducting plate 13 can be attached to the bottom of the air detector 14. At this time, the thermal grease can fully absorb the surface heat of the air detector 14 and transfer it to the heat-conducting plates 13. Then, the heat can be diffused to the surroundings through multiple heat dissipation vents 12 to achieve a rapid cooling effect, thereby preventing the air detector 14 from malfunctioning due to prolonged overheating.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all connected to the external main controller and 220V mains power. The main controller is a conventional known device that can play a control role.

[0044] The working principle of this utility model is as follows:

[0045] In use, multiple air quality detectors 14 can be installed on corresponding detection racks 11. This allows for distributed detection by the multiple detectors 14, enabling simultaneous air quality monitoring at multiple locations within the room. This effectively expands the sampling range of the detection device, covering the entire indoor space and improving the accuracy of the detection data. The connecting block 10 can move the detection rack 11 along with the air quality detectors 14 along the inner wall of the adjustment cavity 9, extending the length of the connecting block 10. This allows for expanding the detection range of each air quality detector 14 as needed. The driving cylinder 6 can drive the lifting plate 7 along with each detector... The components move up and down together to adjust the detection height of each detection component as needed. In addition, the rotating base 3 can drive the lifting mechanism to rotate together with each detection component to adjust the detection angle of each detection component as needed. When the air detector 14 is installed on the corresponding detection frame 11, the top of each heat-conducting plate 13 can be attached to the bottom of the air detector 14. At this time, the thermal grease can fully absorb the surface heat of the air detector 14 and transfer it to the heat-conducting plate 13. Then, the heat can be diffused to the surroundings in time through multiple heat dissipation ports 12 to achieve a rapid cooling effect, thereby preventing the air detector 14 from malfunctioning due to prolonged overheating.
