Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown in the figure, a portable air station maintenance device provided by this utility model includes a housing 1. A rotating rod 5 is connected to a bearing on one side of the outer wall of the housing 1. One end of the rotating rod 5 extends into the interior of the housing 1 and is fixed with a worm gear 2. A motor 4 is fixed inside the housing 1. A worm 3 is fixed to the output shaft of the motor 4. The worm 3 meshes with the worm gear 2. An extension rod 6 is hinged to one end of the rotating rod 5. A limit sleeve 11 is sleeved on the outside of the extension rod 6. A central rod 7 is fixed to one end of the extension rod 6. A cleaning head 8 is fixed to one end of the central rod 7.

[0023] Specifically, in this embodiment, a housing 1 is included. A rotating rod 5 is connected to a bearing on one side of the outer wall of the housing 1. One end of the rotating rod 5 extends into the interior of the housing 1 and a worm gear 2 is fixed thereon. A motor 4 is fixed inside the housing 1, and a worm 3 is fixed to the output shaft of the motor 4. The motor 4 drives the worm 3 to rotate, and the worm 3 meshes with the worm gear 2. When the worm 3 rotates, it can drive the worm gear 2 to rotate. An extension rod 6 is hinged to one end of the rotating rod 5. A limiting sleeve 11 is sleeved on the outside of the extension rod 6. When the limiting sleeve 11 is sleeved at the hinge point of the rotating rod 5 and the extension rod 6, the extension rod 6 cannot rotate with the rotating rod 5. A central rod 7 is fixed to one end, and a cleaning head 8 is fixed to the other end of the central rod 7. The cleaning head 8 is made of non-woven fabric and contains anhydrous ethanol or petroleum jelly. According to maintenance specifications, after cleaning the impact plate inside the PM10 and PM2.5 cutter, petroleum jelly needs to be applied for maintenance. Therefore, the central rod 7 and the cleaning head 8 containing anhydrous ethanol or petroleum jelly can be separately sealed and packaged, and the packaging should indicate whether it contains anhydrous ethanol or petroleum jelly. This way, when using it, you can simply carry the cleaning head 8 containing anhydrous ethanol and petroleum jelly and open the package. There is no need to carry anhydrous ethanol and petroleum jelly separately.

[0024] This utility model provides a portable air station maintenance device, in which a motor 4 drives a worm gear 3 to rotate, which in turn drives an extension rod 6 and a cleaning head 8 to rotate via a worm wheel 2, making it more convenient to clean and maintain the inside of the cutter used in the air station.

[0025] In another embodiment of this utility model, one end of the extension rod 6 is provided with a square hole 19, and one end of the center rod 7 is provided with a square rod 18. The square rod 18 is inserted into the inside of the square hole 19, so that when the extension rod 6 rotates, it can transmit torque to the center rod 7, thereby preventing slippage between the center rod 7 and the extension rod 6. A squeezing column 13 is movably inserted into the inside of the square hole 19. The outer wall of the extension rod 6 has a movable opening 22 for communicating with the square hole 19. The two outer walls of the squeezing column 13 are fixed with connecting plates 23 located inside the movable opening 22. A sliding sleeve 20 is sleeved on the outside of the extension rod 6. The sliding sleeve 20 is fixed to the connecting plate 23. The movement of the sliding sleeve 20 can drive the push rod 21 to push out the square rod 18 inserted into the square hole 19, thereby making it easier for the cleaning head 8 to detach from the extension rod 6. A battery 9 is provided inside the housing 1. A switch 10 is fixed on one inner wall of the housing 1. The switch 10, the battery 9 and the motor 4 are electrically connected by wires. The switch 10, the battery 9 and the motor 4 are connected in series.

[0026] In another embodiment of this utility model, the inner wall of the limiting sleeve 11 is provided with an annular groove 12, and the outer wall of the extension rod 6 is provided with a guide hole 14. A pressing post 13 is provided inside the guide hole 14. One end of the pressing post 13 is adapted to the annular groove 12. When the end of the pressing post 13 is engaged with the annular groove 12, the limiting sleeve 11 is not easy to slide on the outer wall of the extension rod 6. A spring 15 is provided inside the guide hole 14. The spring 15 is located at the bottom of the pressing post 13 and applies elastic force to the pressing post 13. A limiting groove 17 is provided on the outer wall of the pressing post 13. A limiting post 16 is inserted into the inside of the extension rod 6 and extends into the inside of the limiting groove 17. The limiting post 16 prevents the pressing post 13 from detaching from the guide hole 14. The extension rod 6 is hinged to the rotating rod 5, and the limiting sleeve 11 limits and fixes the extension rod 6 and the rotating rod 5, so that the extension rod 6 can be folded when the device is not in use, thereby reducing the space occupied and making it easy to carry.

[0027] Working principle: When in use, insert the square rod 18 of the center rod 7 into the square hole 19 of the extension rod 6, turn on the switch 10 to connect the battery 9 to the motor 4. When the motor 4 rotates, it drives the worm gear 3 to rotate. The rotation of the worm gear 3 drives the worm wheel 2 and the rotating rod 5 to rotate, which in turn drives the extension rod 6 and the cleaning head 8 to rotate. The impact plate inside the PM10 and PM2.5 cutter used in the air quality monitoring station can be cleaned through the cleaning head 8 with anhydrous ethanol. At the same time, the impact plate can be maintained by applying Vaseline through the cleaning head 8.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
