[0027] Figure 6 It is a structural diagram of the cleaning brush and dustproof net in the utility model.

[0028] A multi-stage booster air pump includes: a support base 1, an air pump and a U-shaped mounting plate 5, the air pump is arranged on the support base 1, the air pump includes a drive motor 2, an air pump body 3 and an air outlet 4, the U-shaped mounting plate 5 is provided with a first shock-absorbing part 6 and a second shock-absorbing part 7, and slide grooves 8 are provided on both sides of the U-shaped mounting plate 5. A circular mounting groove 9 is provided on the side of the air pump body 3 away from the drive motor 2, an outer baffle 10 is provided on the outer side of the circular mounting groove 9, a positioning column 11 is provided in the middle of the circular mounting groove 9, and a dustproof net 12 is slidably connected to the positioning column 11.

[0029] The air pump generates vibration when working. The first shock-absorbing part 6 and the second shock-absorbing part 7 between the support base 1 and the U-shaped mounting plate 5 are used to reduce the vibration amplitude and reduce the noise generated by the vibration; the dust and impurities contained in the external air flow are blocked by the dustproof net 12 to prevent them from entering the interior of the air pump and affecting the service life of the components. The outer baffle 10 can protect the dustproof net 12 and clean it without opening it.

[0030] The first shock absorbing part 6 includes a fixed seat 61, a sliding rod 63 and a limiting plate 65. The interior of the fixed seat 61 is fixedly connected to a first spring 62. The sliding rod 63 is fixedly connected to the lower surface of the support base 1. The limiting plate 65 is sleeved on the sliding rod 63 and slidably connected thereto. A first extrusion plate 64 is provided at the lower part of the sliding rod 63. The first extrusion plate 64 contacts the upper end of the first spring 62.

[0031] When the air pump vibrates, the sliding rod 63 slides downward along the inner wall of the fixed seat 61. At this time, the first extrusion plate 64 squeezes the upper end of the first spring 62, and the limit plate 65 limits and guides the movement of the sliding rod 63; the continuous deformation of the first spring 62 is used to reduce shock, so that the vibration amplitude of the drive motor 2 and the air pump body 3 in the upper and lower directions when working is reduced by the first shock-absorbing part 6.

[0032] The first shock absorbing part 6 further includes sliders 66 , which are arranged on both sides of the support base 1 . The positions of the sliders 66 correspond to the positions of the slide grooves 8 , and the sliders 66 are slidably connected to the slide grooves 8 .

[0033] The slider 66 and the slide groove 8 play a guiding role when the support base 1 vibrates, preventing the air pump from tilting when the vibration amplitude is too large.

[0034] The second shock absorbing part 7 includes a mounting sleeve 71, a second spring 72, a second extrusion plate 73, a movable groove 75 and a second rotating seat 76. The mounting sleeve 71 and the movable groove 75 are arranged on the U-shaped mounting plate 5. The second spring 72 is located inside the mounting sleeve 71. The second extrusion plate 73 is arranged on both sides of the mounting sleeve 71 and is slidably connected thereto. The outer side of the second extrusion plate 73 is fixedly connected to the first rotating seat 74. The first rotating seat 74 is slidably connected to the movable groove 75. The second rotating seat 76 is arranged on the lower surface of the support base 1. A connecting rod 77 is rotatably connected to the second rotating seat 76. The other end of the connecting rod 77 is rotatably connected to the first rotating seat 74.

[0035] When the air pump vibrates, the second rotating seat 76 moves downward, pushing the second extrusion plates 73 and the first rotating seat 74 on both sides to slide toward the middle of the mounting sleeve 71 through the connecting rod 77, squeezing the second spring 72, and the movable groove 75 guides the sliding of the first rotating seat 74; the continuous deformation of the second spring 72 is used to reduce shock, so that the vibration amplitude in the left and right directions of the drive motor 2 and the air pump body 3 when working is reduced by the second shock absorbing part 7.

[0036] The outer baffle 10 includes a baffle body 101 and a side slot 102. The side slot 102 is fixedly connected to both sides of the circular mounting groove 9. The two sides of the baffle body 101 are fixedly connected with a plug-in rod 103. The position of the plug-in rod 103 corresponds to the side slot 102. The baffle body 101 is provided with a plurality of evenly distributed air inlets 104. The middle of the baffle body 101 is rotatably connected with a cleaning brush 105. The cleaning brush 105 extends to the outside of the baffle body 101 and is fixedly connected with a handle 106.

[0037] When installing the outer baffle 10, insert the connecting rod 103 into the side slot 102. At this time, the middle part of the cylindrical cleaning brush 105 corresponds to the positioning column 11. After the installation is completed, the outside air enters from the air inlet 104; after long-term use, turn the outer handle 106 to drive the inner cleaning brush 105 to rotate, and sweep away the dust and impurities accumulated on the dustproof net 12. Then remove the outer baffle 10 to clean the fallen dust, reducing the difficulty of cleaning.

[0038] A plurality of evenly distributed docking grooves 13 are formed on the inner wall of the circular mounting groove 9 , and a plurality of evenly distributed positioning protrusions 14 are provided on the outer side of the frame of the dustproof net 12 . The positions of the positioning protrusions 14 correspond to the docking grooves 13 .

[0039] The docking groove 13 and the positioning protrusion 14 assist in the installation and positioning of the dustproof net 12, and at the same time prevent the dustproof net 12 from shaking when the cleaning brush 105 is rotated, thereby affecting the dust removal effect.

[0040] The working principle of the multi-stage booster air pump provided by the utility model is as follows:

[0041] The air pump generates vibration when working. The first shock-absorbing part 6 and the second shock-absorbing part 7 between the support base 1 and the U-shaped mounting plate 5 are used to reduce the vibration amplitude and reduce the noise generated by the vibration; the dust and impurities contained in the external air flow are blocked by the dustproof net 12 to prevent them from entering the interior of the air pump and affecting the service life of the components. The outer baffle 10 can protect the dustproof net 12 and clean it without opening it.

[0042] Compared with the related art, the multi-stage booster air pump provided by the present invention has the following beneficial effects:

[0043] The air pump vibrates continuously when working, causing noise. The first shock-absorbing part 6 and the second shock-absorbing part 7 between the support base 1 and the U-shaped mounting plate 5 are used to reduce the vibration amplitude, thereby reducing the noise and also reducing the damage to the components caused by the vibration; the dust-proof net 12 blocks dust and impurities in the external air flow, preventing them from entering the interior of the air pump and affecting the service life of the components. The outer baffle 10 can protect the dust-proof net 12 and clean it without opening it, reducing the difficulty of cleaning.
