[0022] See also Figure 1 to Figure 2, a dust collector for preventing dust clogging provided by the present invention is now described. The dust collector for preventing dust clogging comprises a carrier 1, a dust collecting tank 2, a turbo fan 3, an air compressor 4, an air storage tank 5 and an electromagnetic valve 6, wherein the dust collecting tank 2 is arranged on the carrier 1, and a working cavity is provided in the dust collecting tank 2, and an isolation disk 22 is provided in the middle of the working cavity, and the isolation disk 22 divides the working cavity into an upper chamber 201 and a lower chamber 202, and a mounting hole 221 is provided in the middle of the isolation disk 22, and a dust collecting pipe 23 connected to the lower chamber 202 is provided at the lower part of the dust collecting tank 2, and a filter element 21 is installed on the mounting hole 221 and is located in the lower chamber 202, and the inner cavity of the filter element 21 is connected to the upper chamber 201 through the mounting hole 221, and the turbo fan 3 is arranged on the carrier 1, and the suction end of the turbo fan 3 is connected to the upper chamber 201 through the first tube body 101, and the air compressor 4 is connected to the upper chamber 201 through the first tube body 101, and the air storage tank 5 ... 4 is arranged on the carrier 1, the air intake end of the air compressor 4 is communicated with the upper chamber 201 through the second tube body 102, the end of the second tube body 102 located in the upper chamber 201 is provided with an air duct 8, the air duct 8 extends into the inner cavity of the filter element 21, and the side wall of the air duct 8 is circumferentially provided with a plurality of ventilation holes 83 penetrating and arranged toward the inner wall of the filter element 21, the air storage tank 5 is arranged on the carrier 1, the air outlet end of the air compressor 4 is connected to the air storage tank 5 through the third tube body 103, and is used to input compressed air into the air storage tank 5, the air storage tank 5 is connected to the second tube body 102 through the fourth tube body 104, and the air storage tank 5 inputs compressed air into the filter element 21 through the fourth tube body 104 and the second tube body 102, and the solenoid valve 6 is arranged on the fourth tube body 104, and the solenoid valve 6 is intermittently opened and closed, and is used to control the compressed air in the air storage tank 5 to be output in pulsed form.

[0023] In this embodiment, the carrier 1 includes a loading plate 11, a running wheel 13 is provided at the bottom of the loading plate 11, and a handrail 12 is provided at one end of the loading plate 11, so that the vacuum cleaner provided by the present invention can be easily transferred.

[0024] A dust discharge port 24 is provided at the bottom of the lower chamber 202, and a cover 25 is movably connected to the dust discharge port 24. The cover 25 can be a threaded connection or a snap connection without specific limitation. A supporting column 26 is provided between the bottom of the dust removal tank and the carrier plate 11. The supporting column 26 has a certain height so that there is a storage space for placing a dust receiving component between the cover 25 and the carrier plate 11. The dust receiving component is a container with a certain volume, such as a trash can or a trash bin. When it is necessary to discharge the dust accumulated in the lower chamber 202, it is necessary to place the dust receiving component between the end cover and the carrier plate 11, and then open the cover 25, so that the dust accumulated in the lower chamber 202 can be discharged into the dust receiving component through the dust discharge port 24.

[0025] The vacuum cleaner provided by the present invention is capable of preventing dust clogging. Compared with the prior art, when the vacuum cleaner is operating, the air compressor 4 is started at the same time, and a certain amount of compressed air can be stored in the air tank 5. When it is found that the suction force of the vacuum cleaner is insufficient, the vacuum cleaner stops working, and the electromagnetic valve 6 is controlled to be opened and closed intermittently. However, the compressed gas stored in the air tank 5 passes through the fourth tube body 104 and the second tube body 102 in the form of pulses and enters the air duct 8 in sequence, and then is sprayed onto the inner wall of the filter element 21 through the ventilation holes 83 in the air duct 8, so as to form backblowing and vibration on the filter element 21, so that the dust blocked on the side wall of the filter element 21 falls off, thereby improving the filtering efficiency of the filter element 21 and restoring the suction force of the vacuum cleaner.

[0026] In some embodiments, see Figure 1 In order to prevent the compressed air in the air storage tank 5 from entering the air compressor 4 through the second tube body 102 during the back-blowing operation of the filter element 21, thereby causing the problem of compressed air loss, a wind shield valve 7 can be provided at one end of the second tube body 102 close to the air compressor 4. When the back-blowing operation is performed, the wind shield valve 7 is closed, and the wind shield valve 7 cuts off the connection between the second tube body 102 and the air compressor 4, thereby preventing the compressed air in the air storage tank 5 from being output to the air compressor 4. When the air compressor 4 is operating, the wind shield valve 7 is in an open state, so that the second tube body 102 is connected to the air compressor 4, and the air compressor 4 can inhale the air in the dust removal tank through the second tube body 102, and compress the air and store it in the air storage tank 5 through the third tube body 103.

[0027] In some embodiments, in order to improve the filtering performance of the filter element 21, the filter element 21 in the present invention is a PE sintered filter element, and the filtering accuracy of the PE sintered filter element is less than 5 microns. The PE sintered filter element has high mechanical strength and toughness, can withstand high filtering pressure, is not easy to break, and can withstand compressed air impact without damage.

[0028] In some embodiments, see Figures 2 to 4 The above-mentioned air duct 8 includes a connecting section 81 and an operating section 82 connected upper and lower, wherein the connecting section 81 is located in the upper chamber 201 and is used to connect to the second tube body 102, the operating section 82 is located in the inner cavity of the filter element 21, and the ventilation hole 83 is set on the side wall of the operating section 82.

[0029] The connecting section 81 is rotatably connected to the second tube body 102 via a bearing, and a rotating sealing ring is also provided between the connecting section 81 and the second tube body 102 to prevent leakage of compressed air. In this embodiment, the bottom of the working section 82 is closed, and a plurality of ventilation holes 83 in the same cross section of the working section 82 form a hole group. The working section 82 is provided with a plurality of hole groups, and the plurality of hole groups are arranged at intervals from top to bottom. The plurality of ventilation holes 83 in the same hole group are evenly arranged and penetrate the working section 82 along the tangent direction of the circumference of the inner wall of the working section 82. With such an arrangement, when compressed air is ejected from the ventilation holes 83, the compressed air will exert a reaction force on the working section 82 along the tangent direction, which can drive the air duct 8 to rotate so that the compressed air is evenly sprayed on the side wall of the filter element 21.

[0030] In some embodiments, see Figures 2 to 5 A driving disk 84 is sleeved on the connecting section 81, and the driving disk 84 is tilted. A cleaning assembly is also provided inside the dust collector 2, and the cleaning assembly includes two longitudinal rods 91. The two longitudinal rods 91 are symmetrically arranged on both sides of the filter element 21 and are slidably penetrated on the isolation disk 22. A connecting ring 92 is provided between the upper ends of the two longitudinal rods 91. The connecting ring 92 is located in the upper chamber 201. A cleaning ring is connected between the lower ends of the two longitudinal rods 91. The filter element 21 is located inside the cleaning ring. Bristles 94 that abut against the filter element 21 are provided on the circumference of the inner wall of the cleaning ring. A butting portion is provided at the end of one of the longitudinal rods 91. In this embodiment, the abutting portion is a cross bar that is laterally arranged toward one side of the driving disk 84, and the cross bar is away from the longitudinal rod One end of 91 abuts against the upper end surface of the driving disk 84 and is slidably connected to the driving disk 84. In application, a ball bearing can also be set at the end where the cross bar abuts the driving disk 84 to reduce the friction between the cross bar and the driving disk 84. In application, when the compressed air drives the air duct 8 to rotate, the driving disk 84 rotates with the rotation of the air duct 8, and the cross bar slides on the upper end surface of the driving disk 84. Since the driving disk 84 is arranged at an angle, when the driving disk 84 rotates, it will drive the cross bar to carry the longitudinal rod 91 to slide up and down, so that the cleaning ring 93 carrying the bristles 94 moves up and down to clean the outer side wall of the filter element 21. By cleaning the outer side wall of the filter element 21, the filtering effect of the filter element 21 can be further improved.

[0031] Optionally, there are multiple cleaning rings 93 , which are spaced apart from each other. During operation, the multiple cleaning rings 93 move up and down so that the cleaning range of the bristles 94 covers the entire outer side wall of the filter element 21 .

[0032] In some embodiments, an elastic component is connected between the upper ends of the two longitudinal rods 91 and the top of the dust collector 2. In this embodiment, the elastic component is a coil spring 95. The coil spring 95 applies a pulling force to the longitudinal rod 91 to balance the gravity of the longitudinal rod 91, thereby reducing the force of the driving disk 84 to lift the longitudinal rod 91, so that the longitudinal rod 91 can be easily driven up and down.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
