Description

Technical Field

[0001] The utility model belongs to the field of air quality detection devices, and in particular relates to an air quality detection device. Background Art

[0002] In a dust-free workshop, in order to ensure good air quality in the workshop, it is usually necessary to use an air quality detection device to detect the air to prevent the dust in the workshop from affecting the workshop environment. However, the existing air quality detection devices often blow air into the dust sensor through a fan to detect the dust in the air. After the detection is completed, the air is discharged back into the workshop environment, which accelerates the flow of dust in the air. Although some detection devices are equipped with filters, dust may clog the filters after long-term use. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. An air quality detection device exemplified in the utility model. When using the device, start the exhaust fan and the dust sensor, and the air enters the air duct through the exhaust fan. When passing through the dust sensor, the dust sensor detects the dust concentration in the air. Then the air enters the tubular filter and is discharged from the mesh holes of the tubular filter, while the dust is filtered by the mesh holes and falls into the collection tube under the action of gravity. After using it for a period of time, the collection tube is opened to clean the dust in the collection tube. Through the device, in the process of air quality detection, the dust in the detected air can be filtered and collected, avoiding the situation that the air with dust is discharged back into the environment after the air detection, which instead accelerates the flow of dust in the air.

[0014] 2. An air quality detection device according to an example of the utility model, when in use, dust slides into the lower tube through the upper tube for collection. After a period of time, the tube cover can be opened to clean the dust in the lower tube, which has the advantage of easy cleaning.

[0015] 3. An air quality detection device according to an example of the utility model, when in use, starts the motor, and the rotation of the motor drives the rotating shaft and the bristles to rotate, so as to clean the inner wall of the tubular filter and better clean the dust attached to the inner wall of the tubular filter, making it easier for the dust to fall.

[0016] 4. An air quality detection device according to an example of the utility model, when in use, controls the electric telescopic rod to extend, the disc can move downward and then be inserted into the hole of the circular ring, thereby blocking the passage between the air duct and the tubular filter. At this time, the air in the tubular filter below no longer flows, which can better facilitate the dust to fall into the collection pipe. Subsequently, the electric telescopic rod is controlled to contract, so that the disc can rise and separate from the circular ring, thereby restoring the air flow.

[0017] 5. In an air quality detection device according to an example of the utility model, the pressing block can be inserted into the lower tube when it descends following the rotating shaft, so as to squeeze the dust in the lower tube and allow the lower tube to contain more dust.

[0018] 6. An air quality detection device in the example of the utility model can make the dust falling on the surface of the pressing block slide down along the inclined surface through the conical pressing block.

[0019] 7. An air quality detection device in the example of the utility model can support the exhaust fan through supporting legs. BRIEF DESCRIPTION OF THE DRAWINGS
