This facilitates the adjustment of the position of the locking block 516, thereby enabling the installation and disassembly of the filter collection frame 511 and the installation tube 4, satisfying the air intake filtration while facilitating subsequent cleaning.

[0030] Furthermore, the slide plate 515 is slidably connected to the connecting box 513, the locking block 516 is slidably connected to the connecting box 513, and the fixing block 512 and the locking block 516 are provided with grooves at corresponding positions, and the locking block 516 is inserted into the groove, which makes the filtration process more stable.

[0031] Furthermore, the impurity removal component 52 includes a first connecting platform 521, which is fixedly connected to the front of the mounting tube 4. A second connecting platform 522 is fixedly connected to the back of the mounting tube 4. A threaded rod 523 is rotatably connected inside the first connecting platform 521. A limiting rod 526 is fixedly connected inside the second connecting platform 522. A movable scraper 524 is slidably connected to the outside of the limiting rod 526. A bellows baffle 525 is fixedly connected to the outside of the movable scraper 524 to facilitate adjustment of the position of the movable scraper 524, thereby satisfying the need to scrape and filter impurities adhering to the inner wall of the mounting tube 4 and increase the cleaning effect.

[0033] Example 2:

[0034] Please see Figures 5-6 Furthermore, in conjunction with Embodiment 1, the auxiliary installation mechanism 6 includes a fixing tube 61, which is fixedly connected to the top of the installation tube 4. A connecting tube 62 is inserted inside the fixing tube 61. A second spring 64 is fixedly connected to the outside of the fixing tube 61. A connecting sleeve 63 is fixedly connected to the top of the second spring 64. A limiting ball 65 is movably connected inside the fixing tube 61, which facilitates the adjustment of the position of the limiting ball 65, thereby satisfying the need for rapid installation between the fixing tube 61 and the connecting tube 62.

[0035] Furthermore, a slanted groove is provided at the corresponding position of the connecting sleeve 63 and the limiting ball 65, and the limiting ball 65 contacts the connecting sleeve 63. A groove is provided at the corresponding position of the connecting pipe 62 and the limiting ball 65, and the limiting ball 65 is movably connected inside the groove, which facilitates a more stable installation process.

[0036] In actual operation, when this device is used, the threaded rod is first made of T-type thread to provide self-locking. The related moving mechanisms of this device use sealing rings to ensure a sealing effect. The operator moves the device to the designated location and, with the locking bolts, completes the installation of the motor mounting base 1 according to the usage environment. After installation, the operator connects the external connecting pipe 62 to the fixed pipe 61 according to usage requirements. The operator pulls the connecting sleeve 63, and through the movement of the connecting sleeve 63, in conjunction with the second spring 64, the limiting ball 65 moves along the inclined groove opened in the connecting sleeve 63, thereby adjusting the position of the limiting ball 65. Then, the connecting pipe 62 is inserted into the fixed pipe 61, and the connecting sleeve 63 is released, allowing the limiting ball 65 to engage with the connecting pipe 62. After insertion and installation, the motor inside the motor mounting housing 2 operates, causing the eccentric impeller inside the vacuum pump housing 3 to rotate and begin operation. The intake air is filtered through the filter collection frame 511. When the filter collection frame 511 needs cleaning, the operator pulls the sliding plate 515. The movement of the sliding plate 515, in conjunction with the first spring 514, causes the locking block 516 to move, which, in conjunction with the fixing block 512, completes the installation and removal of the filter collection frame 511 from the mounting tube 4. When cleaning the mounting tube 4, the operator uses a hex wrench or other tools to rotate the threaded rod 523. The rotation of the threaded rod 523, in conjunction with the limit rod 526, causes the movable scraper 524 to move, thereby satisfying the need to scrape and filter impurities adhering to the inner wall of the mounting tube 4.
