Technical Field

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

[0002] Air detection in a broad sense refers to the detection of air components. Air detection in a narrow sense mainly focuses on indoor air detection from the perspective of application. It refers to the detection of air quality by releasing harmful substances contained in indoor decorative materials and furniture into the home and office environment, causing decoration pollution.

[0003] A Chinese patent publication (publication number: CN202020553129.6) discloses a convection-type environmentally friendly air detection device. The convection-type environmentally friendly air detection device of the utility model embodiment can realize the convection path of air through the air inlet and the air outlet on the handheld shell, and accelerate the air entering the inside of the handheld shell from the air inlet through the air convection device. The accelerated air quickly circulates to the air detection module located at the air outlet. The air detection module can obtain sufficient detection gas and detect the gas. The air convection device realizes the guidance of the air convection direction and accelerates the convection speed of the air. The convection-type environmentally friendly air detection device of the utility model embodiment can accelerate the convection of the detection air, can capture sufficient detection samples, and make the measurement result accurate;

[0004] Although the air detection device accelerates the speed of air circulation by setting up an air convector, the way in which the air directly enters the shell through the air inlet causes dust to enter the shell along with the air, which can easily affect the detection result. For this reason, an ecological air detection device is proposed. Utility Model Content

[0027] In one embodiment, two mounting holes 6 are provided on the upper surface of the rectangular box 2, and the inner walls of the mounting holes 6 are fixedly connected to the outer side of the air intake pipe 3. The provision of the mounting holes 6 facilitates the fixing of the air intake pipe 3.

[0028] In one embodiment, a circular ring 8 is fixedly mounted on the inner wall of the air inlet pipe 3, and the upper surface of the circular ring 8 is in active contact with the lower surface of the filter screen plate 7. With the setting of the circular ring 8, the installation position of the filter screen plate 7 is limited.

[0029] In one embodiment, two guide grooves 402 are provided on the inner wall of the air inlet pipe 3, and the two guide grooves 402 are symmetrically arranged. Two limit blocks 404 are fixedly installed on the outer side of the filter screen plate 7, and the two limit blocks 404 are symmetrically arranged. Two limit grooves 403 are provided on the inner wall of the air inlet pipe 3, and the two limit grooves 403 are symmetrically arranged. The limit grooves 403 are connected to the guide grooves 402. A rectangular plate 401 is movably provided above the two air inlet pipes 3, and two connecting rods 405 are rotatably installed inside the rectangular plate 401, and the bottom end of the connecting rod 405 extends to Below the rectangular plate 401, the bottom end of the connecting rod 405 is fixedly connected to the upper surface of the filter screen plate 7, and the top end of the connecting rod 405 extends to the top of the rectangular plate 401. A circular plate 407 is fixedly installed on the top end of the connecting rod 405. The circular plate 407 is rotated to drive the connecting rod 405 and the filter screen plate 7 to rotate. When the filter screen plate 7 rotates, the two limit blocks 404 are driven to rotate, and the rectangular plate 401 is pulled to drive the filter screen plate 7 and the limit blocks 404 to move along the guide groove 402, so as to facilitate the removal of the filter screen plate 7 from the inside of the intake pipe 3 for cleaning.

[0030] In one embodiment, two through holes 406 are opened on the upper surface of the rectangular plate 401, and bearings 408 are fixedly installed inside the through holes 406. The inner wall of the bearing 408 is fixedly connected to the outer side of the connecting rod 405. Under the setting of the bearing 408, the connecting rod 405 can rotate inside the rectangular plate 401.

[0031] In one embodiment, the outer side of the limit block 404 is in movably contact with the inner wall of the guide groove 402, and the outer side of the limit block 404 is in movably contact with the inner wall of the limit groove 403. The guide groove 402 guides the movement of the limit block 404, and the limit groove 403 limits the limit block 404 and the filter screen plate 7 at the same time.

[0032] When the utility model is working: when it is necessary to detect the air, the axial flow fan 5 is started, so that the outside air enters the interior of the rectangular box 2 through the two air inlet pipes 3, and at the same time, the air inside the rectangular box 2 enters the interior of the shell 1 for detection under the action of multiple air inlet holes 9. When the air enters the interior of the rectangular box 2 through the two air inlet pipes 3, the dust in the air is filtered under the action of the two filter screens 7, effectively preventing the dust in the air from entering the interior of the shell 1 and affecting the air detection result;

[0033] When the filter screen plate 7 needs to be disassembled for cleaning, the circular plate 407 is rotated clockwise in sequence, so that the circular plate 407 drives the connecting rod 405 to rotate. The connecting rod 405 drives the filter screen plate 7 to rotate on the upper surface of the ring 8 at the same time. The rotation of the filter screen plate 7 drives the two limit blocks 404 to rotate at the same time. The limit blocks 404 rotate inside the limit groove 403 until one side of the limit block 404 is rotated to contact one side of the guide groove 402. The limit blocks 404 inside the two air inlet pipes 3 are rotated to contact one side of the guide groove 402. At this time, the rectangular plate 401 is pulled upward, so that the rectangular plate 401 drives the two connecting rods 405 to move upward, and the moving connecting rods 405 are moved upward. The connecting rod 405 drives the filter screen plate 7 to move upward. At this time, the filter screen plate 7 drives the two limit blocks 404 to move upward along the guide groove 402 until the filter screen plate 7 is completely removed from the inside of the air intake pipe 3. The filter screen plate 7 can then be cleaned, making it convenient to take out the two filter screen plates 7 for cleaning at the same time, thereby improving the portability during use. After cleaning, the filter screen plate 7 is pushed to drive the two limit blocks 404 to move downward along the guide groove 402, and then the circular plate 407 is rotated counterclockwise, so that the circular plate 407 drives the connecting rod 405 and the filter screen plate 7 to rotate counterclockwise. At this time, the limit block 404 is stuck in the inside of the limit groove 403 to limit and fix the filter screen plate 7.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
