[0002] With the acceleration of the industrialization process and the continuous improvement of the urbanization level, the problem of air pollution has become increasingly prominent, and various pollutants in the atmospheric environment pose a serious threat to human health. Therefore, real-time monitoring of air quality has become an important means to prevent health problems.

[0003] In current air quality monitoring equipment, the detection sensor is usually arranged inside the equipment. However, there is often a distance between the air inlet and outlet of the detection sensor and the housing, resulting in the detected air possibly coming from both inside and outside the equipment at the same time. Since the air inside the equipment will have a temperature rise due to the operation of the equipment, its temperature may be different from the air in the external environment, thus affecting the accuracy of the detection data.

[0004] Therefore, there is an urgent need to provide a sensor air flow duct structure for air detection nowadays to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies and defects of the prior art, and provide a sensor air flow duct structure for air detection, which can effectively improve the accuracy of air detection data.

[0006] The purpose of the utility model is achieved by the following technical solutions:

An air inlet duct and an air outlet duct are arranged on one side of the base. The detection sensor is arranged on the base. The air inlet of the detection sensor is oppositely arranged with the air inlet duct, and the air outlet of the detection sensor is oppositely arranged with the air outlet duct. There is an air flow inlet between the air inlet of the air inlet duct and the base, and an air flow outlet between the air outlet of the air outlet duct and the base. External air enters the air inlet duct from the air flow inlet, and the detected air is discharged from the air flow outlet through the air outlet duct.

[0028] The following further describes the present utility model in detail in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0029] The specific implementation process of the present utility model is as follows:

[0030] As Figures 1 to 9 shown, a sensor air flow duct structure for air detection includes a base 1, an outer shell 2, and a detection sensor 3. The outer shell 2 covers the upper part of the base 1. An air inlet duct 4 and an air outlet duct 5 are provided on one side of the base 1. The detection sensor 3 is disposed on the base 1. The air inlet 11 of the detection sensor 3 is disposed opposite to the air inlet duct 4, and the air outlet 12 of the detection sensor 3 is disposed opposite to the air outlet duct 5. An air inlet 6 is provided between the air inlet of the air inlet duct 4 and the base 1, and an air outlet 7 is provided between the air outlet of the air outlet duct 5 and the base 1. External air enters the air inlet duct 4 through the air inlet 6, and the detected air is discharged from the air outlet 7 through the air outlet duct 5. Through the air inlet duct 4 and the air outlet duct 5, there is no gap between the detection sensor 3 and the inner wall of the outer shell 2. During detection, external air directly enters and exits the detection sensor 3 through the air inlet 6 and the air outlet 7. This avoids the situation where external air enters the interior of the device and is affected, and then is detected by the detection sensor 3, resulting in inaccurate detected data. Specifically, the base 1 is in the shape of a gear. The air inlet of the air inlet duct 4 abuts against the gear teeth 8 of the base 1, and the gap between the tooth groove and the air inlet forms the air inlet 6. The air outlet of the air outlet duct 5 abuts against the gear teeth 8 of the base 1, and the gap between the tooth groove and the air outlet forms the air outlet 7. Refer to Figures 7 - 9, external air enters the air inlet 11 of the detection sensor 3 from A1, and the detected air is discharged from the air outlet 12 of the detection sensor 3 at A2. A plurality of drainage columns 9 are provided on the inner walls of the air inlet pipe 4 and the air outlet pipe 5. The plurality of drainage columns 9 are arranged in parallel, and the plurality of drainage columns 9 are connected to the gear teeth 8. The pipe walls of the air inlet pipe 4 and the air outlet pipe 5 respectively have inclined surfaces 15, and the inclination angles of the inclined surfaces 15 with the outer side walls of the pipes are both 30° - 60°. A fan (not shown in the figure) is provided inside the detection sensor 3, and the fan is arranged opposite to the air outlet 12. By designing the drainage columns 9 and the inclined surfaces 15 and cooperating with the operation of the fan, the external air can enter the air inlet pipe 4 evenly through the air flow inlet 6, enter the air inlet 11 of the detection sensor 3 through the air inlet pipe 4, then the detection sensor 3 detects the entering air, and the detected air is discharged from the air outlet 7 through the air outlet pipe 5 of the detection sensor 3, and circulates in turn. The external air directly enters the detection sensor 3, effectively improving the air detection efficiency. The air flow inlet 6 and the air flow outlet 7 are hidden in the tooth grooves between the gear teeth, which has concealment and improves the overall aesthetics of the product. The air flow duct structure designed by the present utility model is applicable to detection sensors such as PM2.5, PM10, temperature, and humidity.

[0031] In an embodiment of the present utility model, the air outlet of the air inlet pipe 4 is fitted and connected to the air inlet 11 of the detection sensor 3 to prevent the air entering from the air inlet pipe 4 from entering the equipment interior through the connection gap between the air inlets 11 of the detection sensor 3 without entering the interior of the detection sensor 3; the air inlet of the air outlet pipe 5 is fitted and connected to the air outlet 12 of the detection sensor 3 to prevent the detected air from not being discharged from the air flow outlet 7.

[0032] In an embodiment of the present utility model, it further includes a sensor mounting position 13. The sensor mounting position 13 is provided on the base 1 and is located on one side of the air inlet pipe 4 and the air outlet pipe 5. The detection sensor 3 is fixedly mounted on the sensor mounting position 13 by double-sided tape.

[0033] In an embodiment of the present utility model, it further includes a bottom cover 10. The bottom cover 10 is fixedly attached to the outer surface of the side of the base 1 away from the outer shell 2 by double-sided tape.

[0034] In an embodiment of the present utility model, a buckle member 14 is further provided on the gear teeth 8 of the base 1. The buckle member 14 is L-shaped, and the outer shell 2 and the base 1 are tightly clamped and connected through the buckle member 14. A plurality of buckle members 14 are provided and are evenly arranged along the circumference of the base 1 to tightly clamp and connect the outer shell 2 and the base 1. The detection sensor 3 is covered inside by the outer shell 2 and the base 1, improving the overall aesthetics of the product.

[0035] The base 1, the sensor mounting position 13, the air inlet pipe 4, and the air outlet pipe 5 of the present utility model are integrally formed and connected, which is convenient for processing and manufacturing.

[0036] The embodiments described above only represent the implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
