Meshing connection, the rear side of the hollow rod 8 is fixedly connected with a second filter screen 10, the outer side of the second filter screen 10 is rotatably connected to the inner middle part of the air intake pipe 5, the rear side of the inner wall of the air intake pipe 5 is fixedly connected with a cross plate 11, the rear side of the cross plate 11 is fixedly connected with a motor 12, the output end of the motor 12 passes through the cross plate 11 and is fixedly connected with a fan blade 13, the front side of the fan blade 13 is fixedly connected with the second filter screen 10, the rear side of the air intake pipe 5 is connected with an air intake cover 14, the bottom of the air intake pipe 5 is connected with a dust box 15, and the bottom of the generator housing 1 is provided with a fixing mechanism 2;

[0030] Specifically, by starting the motor 12, the fan blades 13 can rotate counterclockwise to suck the external airflow into the air intake pipe. The filter opening of the first filter 6 is slightly smaller than the second filter 10. As the fan blades 13 rotate, the second filter 10 also rotates counterclockwise. Such a design can enhance the interception capacity of the second filter 10 for larger impurities. At the same time, the rotation of the fan blades 13 will drive the second bevel gear 9 on the hollow rod 8 to rotate counterclockwise, and through the meshing transmission, drive the first bevel gear 7 and the first filter 6 to rotate clockwise. The rotation of the first filter 6 improves the interception efficiency of small impurities. The relative reverse rotation of the first filter 6 and the second filter 10 can evenly cover the space inside the entire air intake pipe 5, which helps to capture particulate matter in the air more evenly and avoid dead angles or blind spots that may be formed. The intercepted impurities will fall into the dust box 15 for collection, thereby achieving sufficient filtration of impurities in the air.

[0032] Specifically, the U-shaped plate 201 is used to fix the generator housing 1, and the mounting plate 209 is used to firmly mount the device on the ground or other locations. The mounting plate 209 can be moved up and down by starting the electric telescopic rod 203, and the rotating rod 202 can be driven to rotate. The rotating rod 202 pushes the U-shaped block 204 to move forward and backward, thereby enhancing the stability of the lifting process.

[0034] Specifically, the slide groove 23 can improve the stability of the U-shaped block 204 during movement, and the device can be easily fixed by installing a threaded member in the positioning hole 22 on the positioning block 21. The controller 16 can control the starting and operating power between the oxygen generator 3, the motor 12 and the electric telescopic rod 203 respectively.

[0036] Specifically, the protection capability of the controller 16 can be improved through the shell 17, the controller 16 can be prevented from being accidentally touched when not in use by opening and closing the protective cover 18, the protection capability of the oxygen generator 3 in the generator shell 1 can be improved by the heat dissipation cover 20, and the device can be easily moved by the handle 24.

The filter opening of the first filter 6 is slightly smaller than the second filter 10. As the fan blades 13 rotate, the second filter 10 also rotates counterclockwise to enhance its ability to intercept larger impurities.

The intercepted impurities will fall into the dust box 15 for collection, realizing the removal of impurities in the air. The impurities in the air can be fully filtered, and the intercepted impurities will fall into the dust box 15 for collection, so that the impurities in the air can be fully filtered, thereby improving the reliability of the device, and the U-shaped plate 201 can be used to fix the generator housing 1, and the device can be fixed on the ground or other installation positions through the mounting plate 209, and the mounting plate 209 can be started to move the mounting plate 209 up and down, and drive the rotating rod 202 to rotate, and the rotating rod 202 can be rotated to push the U-shaped block 204 to move forward and backward to improve the stability of the lifting process, and the movable plate 207 can be moved forward and backward along the fixed plate 205 by rotating the threaded rod 206, pushing the generator housing 1 to contact the positioning plate 208, so that while fixing the generator housings 1 and oxygen concentrators 3 of different sizes, their upper and lower height positions are adjusted, and the impact on the device is buffered, thereby improving the practicability of the device.
