Description

Technical Field

[0001] This utility model relates to the field of air detection, and more specifically, to an air detector. Background Technology

[0002] Given the current state of air pollution in China and the rapid development of the health industry, people are paying increasing attention to air pollution indicators. Indoor air pollution is particularly prominent in the context of home renovation, where harmful substances such as formaldehyde, benzene compounds, and VOCs (volatile organic compounds) are released in large quantities from building materials, and long-term exposure can pose serious health risks.

[0003] Using air quality monitors allows for real-time monitoring of the concentration of these pollutants, providing crucial information for assessing the safety of the living environment.

[0004] Existing air quality detectors have an air inlet for direct air intake, which easily creates turbulence in the airflow within the pipe, resulting in uneven air mixing. Consequently, the concentration of samples collected by the sensor at different times varies greatly, leading to poor data stability.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an air detector that achieves high-precision detection by stabilizing airflow through a spiral air intake pipe.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an air detector includes a main body, a detection sensor, and an air pump. An air inlet pipe is provided at the top of the main body, and a spiral air inlet pipe is provided at the end of the air inlet pipe away from the main body. An air inlet cover is provided on the air inlet pipe. The air inlet cover is hollow inside and encloses the spiral air inlet pipe. Several air ports are circumferentially opened on the air inlet cover.

[0008] The present invention is further configured such that: the air intake cover includes a separable and combinable upper cover and a lower cover, the lower cover is penetrated and fixedly connected by an air intake pipe, and a filter screen annular groove is provided on the inner bottom surface of the lower cover, and a coarse filter screen is detachably connected in the filter screen annular groove.

[0009] The present invention is further configured such that: a first magnet is provided on the lower cover, and a second magnet matching the first magnet is provided on the upper cover, so that the upper cover and the lower cover can be separated and combined through the first magnet and the second magnet.

[0010] The present invention is further configured such that: the main body is provided with a display screen for displaying the concentration values ​​of various air pollutants.

[0011] In summary, this utility model has the following beneficial effects:

[0012] This invention extends the airflow path by incorporating a spiral air intake pipe, resulting in a smoother airflow and thus improving the detection accuracy of the sensor. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: An air detector, such as Figure 1-3 As shown, the air detector includes a main body 1, a detection sensor, and an air pump. An air inlet pipe 2 is located at the top of the main body 1, one end of which is connected to the air pump inside the main body 1, and the other end extends into a spiral air inlet pipe 3. The spiral air inlet pipe 3 is covered by a hollow air inlet shroud 4, which has several air ports 5 circumferentially arranged. Air enters through the air ports 5 and is drawn by the air pump along a spiral path to the detection sensor. This reduces turbulence, improves airflow uniformity, and enhances air detection accuracy. Simultaneously, the airflow velocity is reduced by passing through the air ports 5 and the coarse filter, further reducing the air velocity within the air inlet pipe 2 and extending the residence time of the air on the sensor surface, allowing the sensor to fully respond to pollutant concentrations.

[0019] During testing, the air pump is started, and outside air enters through the air inlet 5. After being filtered by the coarse filter to remove large particles, the air flows along the spiral air inlet pipe 3 to form a swirling flow. Finally, the air pump delivers the air to the detection sensor for analysis, and the data is displayed in real time on the display screen 10.

[0020] like Figure 2 , 3 As shown, the air intake shroud 4 is composed of an upper shroud 6 and a lower shroud 7. The lower shroud 7 is fixed to the air intake pipe 2, and its inner bottom surface is provided with a filter screen ring groove 8 for detachable installation of a coarse filter screen. The upper shroud 6 and the lower shroud 7 are connected by a first magnet 9 and a second magnet, which facilitates quick separation for cleaning or replacement of the filter screen.

[0021] The main body 1 has a display screen 10 on its surface, which displays the concentration values ​​of pollutants such as PM2.5, VOCs, and CO2 in real time, making it easy for users to obtain data intuitively.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
