[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The filter element is then pulled back to allow the filter to filter through the filter element to actuate the filter element and the filter element to move relative to the filter element.

[0015] 2. In the utility model, a connecting device is provided. When the device is in use, the user pulls the handle, and the movement of the handle drives the card plate to move, and the card plate moves on the surface of the limit rod. When the card plate moves, it drives the third spring to displace and deform to generate elastic force, and the card plate moves out of the inside of the card slot, and the connecting pipe loses its restraint. By providing the connecting device, the connecting pipe is effectively fixed, which plays a role in fixing the connecting pipe, reducing the use of the device.

[0023] The specific configuration and function of the filtering device 6 and the connecting device 7 will be described in detail below.

[0024] In this embodiment: a filter device 6 is provided at one end of the connecting tube 4, and the filter device 6 includes a filter frame 61 and a connecting column 62. The connecting column 62 is located at one end of the connecting tube 4 and is fixedly connected. The filter frame 61 is arranged inside the connecting tube 4. The filter frame 61 is located on the surface of the connecting column 62 and is slidably connected. The surface of the connecting column 62 is sleeved with a connecting ring 63. The connecting ring 63 is located inside the connecting column 62 and is slidably connected. One end of the connecting ring 63 is located on the surface of the filter frame 61 and is abutted. The end of the connecting ring 63 away from the filter frame 61 is fixedly connected to a first spring 64. The end of the first spring 64 away from the connecting ring 63 is fixedly connected to the surface of the connecting tube 4. The surface of the connecting tube 4 is fixedly connected to a positioning block 69.

[0025] Specifically, the interior of the positioning block 69 is fixedly connected to the sliding rod 65 , and the surface of the sliding rod 65 is slidably connected to the sliding plate 66 .

[0026] In this embodiment, the slide plate 66 can be moved by providing the slide bar 65 , thereby reducing the difficulty of the slide plate 66 in moving smoothly when the device is in use.

[0027] Specifically, a locking ball 68 is fixedly connected to one side of the middle section of the slide plate 66 close to the connecting column 62 . The locking ball 68 is located on the surface of the connecting column 62 and is engaged. The provision of the locking ball 68 facilitates the positioning of the slide plate 66 .

[0028] Specifically, the surface of the slide rod 65 is sleeved with a second spring 67 , and the two ends of the second spring 67 are respectively located on the surface of the slide plate 66 and the surface of the positioning block 69 and fixedly connected. The second spring 67 is provided to facilitate the application of a reset elastic force to the slide plate 66 .

[0029] In this embodiment: a connecting device 7 is provided at one end of the pipeline 1 close to the connecting pipe 4, and the connecting device 7 includes a slot 71 and a clamping plate 72. The slot 71 is opened on the side of the connecting pipe 4, and the clamping plate 72 is located inside the pipeline 1 for sliding connection. One end of the clamping plate 72 is located inside the slot 71 and clamped. The end of the clamping plate 72 away from the slot 71 is fixedly connected to a pull handle 74, and a limiting rod 73 is fixedly connected to the side of the pipeline 1.

[0030] In this embodiment, by providing the clamping plate 72 , the connecting pipe 4 and the pipeline 1 can be limited and fixed, thereby reducing the difficulty in quickly fixing the connecting pipe 4 to the pipeline 1 when the device is in use.

[0031] Specifically, the clamping plate 72 is slidably connected to the surface of the limiting rod 73 , and the limiting rod 73 is fixedly connected to the limiting block 75 at one end away from the pipeline 1 . The limiting rod 73 is provided to facilitate the limiting movement of the clamping plate 72 .

[0032] Specifically, the surface of the limiting rod 73 is sleeved with a third spring 76 , and both ends of the third spring 76 are fixedly connected to the surface of the card plate 72 and the surface of the limiting block 75 respectively. The third spring 76 is provided to facilitate the application of a reset elastic force to the card plate 72 .

[0033] Working principle: When the device is in use, the user pulls the slide plate 66 toward the end away from the filter frame 61 and moves on the surface of the slide rod 65. Then the slide plate 66 moves, driving the second spring 67 to displace and deform to generate elastic force, and causes the ball 68 to disengage from the inside of the connecting column 62. Then the filter frame 61 loses its restraint, and then the first spring 64 resets and drives the connecting ring 63 to move inside the connecting column 62. The connecting ring 63 moves and pushes the filter frame 61 out of the connecting pipe 4. By setting up the filter device 6, the air entering the device is effectively filtered, and the foreign matter in the air entering the device is filtered, which reduces the situation that when the device is in use, the foreign matter in the air is easily sucked into the device when the device is ventilating the inside of the channel, and hits the power device 5 inside the device, causing damage to the device. The filter device 6 effectively blocks the foreign matter in the air entering the device, protects the power device 5 inside the device, and improves the service life of the device.

[0034] When the device is in use, the user pulls handle 74, and the movement of handle 74 drives the clamping plate 72 to move, and the clamping plate 72 moves on the surface of the limit rod 73. When the clamping plate 72 moves, it drives the third spring 76 to displace and deform to generate elastic force, and the clamping plate 72 moves out of the inside of the clamping groove 71, and the connecting pipe 4 is freed from its restraint. By setting the connecting device 7, the connecting pipe 4 is effectively fixed, which plays a role in fixing the connecting pipe 4 and reducing the use of the device. Generally, when connecting the connecting pipe 4 to the pipeline 1, bolts are used for installation and fixing. The use of bolts requires tools to operate, and the use of tools is too cumbersome, resulting in low work efficiency for the user. The connecting device 7 can quickly connect and install the connecting pipe 4 and the pipeline 1, thereby improving the practicality of the device.
