When the equipment is working, the air intake pipe 11 will inwardly inhale air, and the gas flow drives the fan blades 14 to rotate, thereby driving the first gear 15 and the second gear 17 to rotate. When the second gear 17 rotates, it will drive the third gear 18 to rotate, and the third gear 18 drives the filter cotton 19 to rotate. Through the provided fan blades 14 and the third gear 18, the filter cotton 19 is caused to rotate slowly to maintain the cleanliness above the air intake pipe 11, reduce the dust in the air from gathering above the air intake pipe 11 during long-term use, reduce the influence of dust accumulation inside the filter cotton 19 on the air intake efficiency of the equipment, increase the practicability and convenience of the equipment, and facilitate the use of the equipment by the staff.

[0029] Further, such as Figure 5As shown, a spring 2 is fixedly connected to the bottom of the inner side of the support tube 10; a second support plate 21 is fixedly connected to the end of the outer wall of the spring 2; a first connecting column 22 is fixedly connected to the end of the outer wall of the second support plate 21; two groups of elastic sheets 23 are fixedly connected to the outer wall of the first connecting column 22; the elastic sheet 23 passes through the support tube 10; the elastic sheet 23 passes through part of the filter cotton 19; a second connecting column 24 is fixedly connected to the end of the outer wall of the first connecting column 22. When the equipment is working, the elastic sheet 23 extends into the filter cotton 19. At this time, the support tube 10 rotates with the filter cotton 19, and the support tube 10 rotates on the side wall of the first support plate 101, pressing the second connecting column 24. The first connecting column 22 will move downward, so that the elastic sheet 23 is separated from the filter cotton 19. When the pressure on the second connecting column 24 stops, the spring 2 will rebound upward, so that the elastic sheet 23 reconnects the filter cotton 19. By setting the spring 2 and the elastic sheet 23, the filter cotton 19 can work normally when the equipment is working, thereby increasing the stability of the equipment. When replacing the filter cotton 19, the difficulty of the staff to install the filter cotton 19 is reduced, which is convenient for the staff to maintain the equipment later, and increases the practicality and convenience of the equipment.

[0030] Further, such as Figure 5 As shown, the outer wall of the support tube 10 is fixed with a circular ring 3; the circular ring 3 is in contact with the first support plate 101; the side wall of the first support plate 101 is slidably connected with an I-shaped limit column 31; the I-shaped limit column 31 cannot be separated from the first support plate 101; the I-shaped limit column 31 is in contact with the support tube 10; the bottom of the outer wall of the I-shaped limit column 31 is in contact with the end of the outer wall of the circular ring 3. When the equipment is working, the support tube 10 will rotate, and the I-shaped limit column 31 will be pulled outward, and the I-shaped limit column 31 will be separated from the top of the circular ring 3. When the I-shaped limit column 31 is pushed inward, the I-shaped limit column 31 will be pressed on the top of the circular ring 3. The circular ring 3 and the I-shaped limit column 31 are provided to make the equipment more stable during operation, thereby increasing the stability and practicality of the equipment.

[0031] Further, such as Figure 6 As shown, a support column 4 is fixedly connected to the end of the outer wall of the air sampler body 1; a brush plate 41 is fixedly connected to the outer wall of the support column 4; a plurality of brush heads 42 are fixedly connected to the bottom of the outer wall of the brush plate 41; the brush head 42 is in contact with the second gear 17; the brush head 42 is in contact with the first gear 15. When the equipment is working, the second gear 17 and the first gear 15 will rotate, and the surfaces of the second gear 17 and the first gear 15 are cleaned by the brush head 42, reducing the influence of dust or other impurities on the operation of the equipment, increasing the practicality and convenience of the equipment, and facilitating the use of the equipment by the staff.

[0032] Further, such as Figure 2As shown, the inner end of the suction pipe 11 is fixedly connected with a valve 5; the valve 5 is made of plastic. When the device is working, the gas will flow into the interior of the atmospheric sampler body 1 along the suction pipe 11 due to the suction force. At this time, the valve 5 will open, and when the device stops working, the suction force will gradually stop, and the valve 5 will close. By setting the valve 5, dust and other impurities entering the interior of the device when the device is not working can be reduced, the failure rate of the device can be reduced, and the use of the device by the staff is convenient.

[0033] Further, such as Figure 7 As shown, two sets of threaded columns 6 are bolted to the bottom of the outer wall of the air sampler body 1; the bottom of the outer wall of the threaded column 6 is fixedly connected to a base 61. Before using the device, the air sampler body 1 needs to be placed on a plane. The height of the four angles of the device can be adjusted by setting the threaded column 6 and the base 61, which reduces the device's requirements for the flatness of the plane and increases the practicality of the device.

[0034] Further, such as Figure 7 As shown, the outer wall of the base 61 is fixedly connected with a plurality of trapezoidal blocks 7; the trapezoidal blocks 7 are made of wear-resistant rubber. When installing the equipment, the staff will rotate the base 61. The set trapezoidal blocks 7 can increase the friction between the base 61 and the staff's palm, making it easier for the staff to use and debug the equipment.

[0035] Working principle: When the equipment is working, the air intake pipe 11 will inhale air, and the gas flow drives the fan blade 14 to rotate, which in turn drives the first gear 15 and the second gear 17 to rotate. When the second gear 17 rotates, it drives the third gear 18 to rotate, and the third gear 18 drives the filter cotton 19 to rotate. Through the fan blade 14 and the third gear 18, the filter cotton 19 rotates slowly to maintain the cleanliness above the air intake pipe 11, reduce the dust in the air from gathering above the air intake pipe 11 during long-term use, and reduce the filter cotton 19. The influence of internal dust accumulation on the suction efficiency of the equipment is increased, the practicability and convenience of the equipment are increased, and the use of the equipment by the staff is convenient. When the equipment is working, the elastic sheet 23 extends into the filter cotton 19. At this time, the support tube 10 rotates with the filter cotton 19, and the support tube 10 rotates on the side wall of the first support plate 101, pressing the second connecting column 24, and the first connecting column 22 will move downward, so that the elastic sheet 23 is separated from the fixing of the filter cotton 19. When the pressing of the second connecting column 24 is stopped, the spring 2 will rebound upward, so that the elastic sheet 23 is re-aligned with the filter cotton 19. The filter cotton 19 is connected, and the spring 2 and the elastic sheet 23 are set, so that the filter cotton 19 can work normally when the equipment is working, and the stability of the equipment is increased. When the filter cotton 19 is replaced, the difficulty of the staff to install the filter cotton 19 is reduced, which is convenient for the staff to maintain the equipment in the later stage, and the practicality and convenience of the equipment are increased. When the equipment is working, the support tube 10 will rotate, pull the I-shaped limit column 31 outward, and the I-shaped limit column 31 will be separated from the top of the ring 3. When the I-shaped limit column 31 is pushed inward, the I-shaped limit column 31 will be pressed on the top of the ring 3. The set ring 3 and the I-shaped limit column 31 make the equipment more stable during operation, and the stability and practicality of the equipment are increased. When the equipment is working, the second gear 17 and the first gear 15 will rotate, and the brush head 42 is set to clean the surfaces of the second gear 17 and the first gear 15, reduce the influence of dust or other impurities on the operation of the equipment, increase the practicality and convenience of the equipment, and facilitate the use of the equipment by the staff. When the equipment is working, the gas will flow to the inside of the atmospheric sampler body 1 along the suction pipe 11 due to the suction effect. At this time, the valve 5 will open, and when the device stops working, the suction will gradually stop, and the valve 5 will close. By setting the valve 5, dust and other impurities can be reduced from entering the device when the device is not working, thereby reducing the failure rate of the device and facilitating the use of the device by the staff. Before using the device, the atmospheric sampler body 1 needs to be placed on a plane. The height of the four angles of the device can be adjusted by the set threaded column 6 and the base 61, thereby reducing the requirements of the device on the flatness of the plane and increasing the practicality of the device. When installing the device, the staff will rotate the base 61, and the set trapezoidal block 7 can increase the friction between the base 61 and the palm of the staff, thereby facilitating the use and debugging of the device by the staff.
