DETAILED DESCRIPTION

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the utility model.

[0032] As Figures 1-8 shown, a dust filter for vacuum cleaner, including mounting rack 1, filter core 2, spoiler assembly, accelerated filter assembly and quick dismounting assembly, mounting rack 1 is annular structure setting, and the upper end surface of mounting rack 1 is fixedly connected with support frame 3, and filter core 2 is tubular structure setting;Spoiler assembly includes annular fixed support 4 fixedly connected to the inner wall of mounting rack 1, and rotating motor 5 is fixedly connected to the middle part of annular fixed support 4, and rotating frame 6 is fixedly connected to the inner side of support frame 3, and No. 1 rotating shaft 7 is rotatably connected to the middle part of rotating frame 6, and the lower end of No. 1 rotating shaft 7 is fixedly connected with the output end of rotating motor 5 through a shaft coupling, and the upper end of No. 1 rotating shaft 7 is fixedly connected with fixed bottom plate 8, and fixed bottom plate 8 upper end surface is fixedly connected with spoiler rod 9, and spoiler rod 9 is linearly changed spiral structure.

[0033] The first rotating shaft 7 is driven to rotate by the rotating motor 5, so that the first rotating shaft 7 can drive the fixed bottom plate 8 and the turbulence rod 9 on the upper end surface of the fixed bottom plate 8 to rotate. Since the turbulence rod 9 has a linear spiral structure, the dust-containing air entering the inside of the filter element 2 can be disturbed by the rotating turbulence rod 9, so that the dust-containing air can be concentrated and accumulated in the inside of the filter element 2, thereby avoiding the flow state of the dust-containing air being too dispersed and improving the absorption and filtration rate of the dust filter for the dust-containing air.

[0034] As shown in Figure 1 , Figures 3-5 and Figure 7 , the acceleration filtering assembly is fixedly connected to the inner side of the support frame 3 and is used to actively drive the air acceleration contact filter element 2. The acceleration filtering assembly comprises a plurality of rotating side plates 10 fixedly connected to the inner side of the support frame 3. The rotating side plates 10 are all rotationally connected with a worm 11. A plurality of concave supports 12 are fixedly connected to the inner side of the support frame 3. The rotating frame 6 and the concave supports 12 are both provided with through holes. The worm 11 is matched with the through holes. A second rotating shaft 13 is rotationally connected to each of the concave supports 12. A worm wheel 14 is fixedly connected to the middle part of the second rotating shaft 13. The worm wheel 14 is meshed with the worm 11. The two end parts of the second rotating shaft 13 are both fixedly connected with a plurality of flow driving blades 15. The acceleration filtering assembly further comprises a center gear ring 16 fixedly connected to the outer circumferential wall of the output end of the rotating motor 5. A plurality of transmission gears 17 are fixedly connected to the lower position of the outer wall of the worm 11. The transmission gears 17 are all meshed with the center gear ring 16.

[0035] During the operation of the rotating motor 5, the center gear ring 16 is driven to rotate. The meshing transmission of the transmission gears 17 and the center gear ring 16 is used to drive the worms 11 to rotate. The meshing transmission of the worm 11 and the worm wheel 14 is used to drive the second rotating shaft 13 to rotate. That is, the second rotating shaft 13 and the flow driving blades 15 at the end parts of the second rotating shaft 13 are driven to synchronously rotate. The dust-containing air is pushed by the counterclockwise rotating flow driving blades 15, so as to accelerate the flow speed of the dust-containing air close to the inner wall of the filter element 2. Thus, the dust-containing air is actively driven to accelerate and contact the filter element 2, so as to improve the filtration rate of the filter element 2 for the dust-containing air and improve the overall working efficiency of the vacuum cleaner.

[0036] As shown in Figures 1-4 , Figure 6 and Figure 8As shown, the quick disassembly and assembly component is fixedly connected to the lower end surface of the mounting frame 1, and is used to realize quick mounting and disassembly of the mounting frame 1 and the filter element 2, and the quick disassembly and assembly component comprises a mounting cover plate 18 fixedly connected to the lower end surface of the mounting frame 1, a supporting bottom block 30 fixedly connected to the lower end surface of the mounting cover plate 18, wherein the supporting bottom block 30 is arranged in an arc-shaped structure, two limiting sliding frames 19 fixedly connected to the lower end surface of the mounting cover plate 18, plug-in supports 20 slidably connected to the inner sides of the two limiting sliding frames 19, arc-shaped plates 21 fixedly connected to the end portions of the plug-in supports 20, plug-in shafts 22 fixedly connected to the arc-shaped plates 21, wear-resistant silica gel pads fixedly connected to the outer circumferential walls of the plug-in shafts 22, a first mounting plate 23 fixedly connected to the upper end surface of the mounting frame 1, a second mounting plate 24 fixedly connected to the lower end surface of the filter element 2, wherein the first mounting plate 23 and the second mounting plate 24 are both arranged in an annular structure, and mounting plug-in holes 25 are formed in the side walls of the first mounting plate 23 and the second mounting plate 24, and the plug-in shafts 22 are matched with the mounting plug-in holes 25, and the quick disassembly and assembly component further comprises a balance fixing frame 26 fixedly connected to the inner wall of the mounting frame 1, a low-speed motor 27 fixedly connected to the balance fixing frame 26, and a drive gear 28 fixedly connected to the output end of the low-speed motor 27 and penetrating through the mounting cover plate 18, wherein the end portions of the plug-in supports 20 are fixedly connected with rack rods 29, and the drive gear 28 is meshed with the rack rods 29.

[0037] When the filter element 2 is mounted and used, the low-speed motor 27 can be controlled to start to drive the drive gear 28 to start rotating, and the drive gear 28 and the rack rods 29 are meshed to drive the plug-in supports 20 to move relative to the limiting sliding frames 19, so that the plug-in supports 20 start to move towards the center position of the mounting cover plate 18, and drive the arc-shaped plates 21 and the plug-in shafts 22 to move, so that the plug-in shafts 22 can be sequentially inserted into and pass through the first mounting plate 23 and the second mounting plate 24, so as to quickly and fixedly connect and mount the mounting frame 1 and the filter element 2, and when the filter element 2 is dismounted and used, the plug-in supports 20 are driven to move in the opposite direction, so that the plug-in supports 20 move away from the center position of the mounting cover plate 18, and then the plug-in shafts 22 are no longer inserted and fixed to the first mounting plate 23 and the second mounting plate 24, so that the mounting frame 1 and the filter element 2 can be separated, thereby realizing quick mounting and disassembly of the mounting frame 1 and the filter element 2, and being beneficial to improving the maintenance and cleaning work efficiency and convenience of the filter element 2.

[0038] The working principle of the utility model is as follows:

[0039] 1. During use, the vacuum cleaner can draw dusty air into the filter element 2. At this time, the rotary motor 5 can be started, and the rotary motor 5 drives the first rotating shaft 7 to rotate. The first rotating shaft 7 can drive the fixed base plate 8 and the baffle rod 9 on its upper end face to rotate. Since the baffle rod 9 has a linear spiral structure, the rotating baffle rod 9 can be used to turbulent the dusty air entering the filter element 2, so that the dusty air can be concentrated and accumulated inside the filter element 2. This can avoid the dusty air flow state being too dispersed and improve the dust filter's absorption and filtration rate of dusty air.

[0040] 2. During operation, the rotary motor 5 can drive the central gear ring 16 to rotate. The meshing transmission of several transmission gears 17 and the central gear ring 16 drives several worm gears 11 to rotate. The meshing transmission of the worm gears 11 and the worm wheel 14 drives the second rotating shaft 13 to rotate. This drives several second rotating shafts 13 and their end-end drive blades 15 to start rotating synchronously. It should be noted that the rotation direction of the second rotating shaft 13 is counterclockwise. The counterclockwise rotating drive blades 15 can be used to push the dust-laden air to accelerate the flow speed of the dust-laden air towards the inner wall of the filter element 2. This can achieve active driving of the dust-laden air to accelerate contact with the filter element 2, thereby improving the filtration rate of the filter element 2 for the dust-laden air and improving the overall working efficiency of the vacuum cleaner.

[0041] 3. If maintenance, cleaning, or replacement of filter element 2 is required, during the installation and use of filter element 2, the low-speed motor 27 can be started to drive the drive gear 28 to rotate. The meshing transmission of the drive gear 28 and the rack and pinion 29 drives the insertion bracket 20 to move relative to the limiting slide frame 19, causing the insertion bracket 20 to move towards the center position of the mounting cover plate 18. This also drives the arc plate 21 and the insertion shaft 22 to move, allowing the insertion shaft 22 to sequentially connect to and pass through the first mounting plate 23 and the second mounting plate 24. Plate 24 is provided to facilitate the quick and secure connection and installation of mounting bracket 1 and filter element 2. When filter element 2 is disassembled and used, the reverse drive insertion bracket 20 is moved away from the center position of mounting cover plate 18, so that the insertion shaft 22 no longer inserts and fixes to mounting plate 23 and mounting plate 24, thereby separating mounting bracket 1 and filter element 2. This enables quick installation and disassembly of mounting bracket 1 and filter element 2, which is beneficial to improving the efficiency and convenience of maintenance and cleaning of filter element 2.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
