A through hole 321 that can connect the air intake space 102 and the cleaning space 103 is provided. The shell assembly 3 also includes a valve 34 that can control the opening and closing of the through hole 321, and a cover plate 35 that can open and close the cleaning port 313; a plurality of mounting ports 331 are provided on the rotating plate 33, and filter elements 4 are installed on the mounting ports 331. At least one mounting port 331 is arranged between the air outlet space 101 and the air intake space 102, and at least one mounting port 331 is arranged between the air outlet space 101 and the cleaning space 103. The shell assembly 3 also includes a rotating device 36 that can rotate the rotating plate 33; the cleaning device is arranged in the cleaning space 103 and can clean the dust on the filter element 4 on the upper side of the cleaning space 103.

[0030] Through the above arrangement, firstly, a plurality of filter elements 4 filter together, and the filtering efficiency is high; secondly, the dust can be cleaned in batches, and the dust collector continues to remove dust without being affected during the cleaning, thereby reducing the influence of the cleaning on the dust removal.

[0031] In the present application, the partition 32 is vertically fixedly connected to the lower inner wall of the outer shell 31, the air intake space 102 and the cleaning space 103 are basically rectangular, the air outlet space 101 is basically cylindrical, the rotating plate 33 is circular, and the radius is adapted to the radius of the air outlet space 101, so that the rotating plate 33 rotates and is sealed at the lower end of the air outlet space 101; the rotating device 36 is connected to the center of the rotating plate 33; the valve 34 can be set as a solenoid valve for easy control; the filter element 4 can be set as a filter screen; the cleaning device can refer to the existing dust collector.

[0032] When the dust collector of the present application is removing dust, the valve 34 is opened, the air intake space 102 is connected with the cleaning space 103 through the through hole 321, the cover plate 35 closes the cleaning port 313, and air enters the air intake space 102 from the air intake port 311, and a part of the air enters the cleaning space 103 through the through hole 321. The air in the air intake space 102 enters the air intake space 102 through the filter element 4 between the air intake space 102 and the air outlet space 101, and the air in the cleaning space 103 enters the air outlet space 101 through the filter element 4 between the cleaning space 103 and the air outlet space 101. The multiple filter elements 4 filter the air so that the air can be dust-free, and the filtered air is output from the air outlet 312. When cleaning is needed, the valve 34 is closed, the cover plate 35 is opened, and the cleaning device cleans the filter element 4 on the upper side of the cleaning space 103, that is, the air outlet The filter element 4 between the air intake space 102 and the air outlet space 101, and the dust cleaned is cleaned out through the cleaning port 313. During the cleaning process, the air can still move to the air outlet 312 through the air intake space 102, the filter element 4, and the air outlet space 101, that is, the filter element 4 between the air intake space 102 and the air outlet space 101 can still continue to filter the air, thereby reducing the impact of cleaning on dust removal; after the cleaning is completed, the cover plate 35 is closed, the valve 34 is opened, and all the filter elements 4 can continue to filter the air; when it is necessary to clean the filter element 4 between the air intake space 102 and the air outlet space 101, the rotating device 36 drives the rotating plate 33. After the rotating plate 33 rotates one hundred and eighty degrees, the positions of the filter elements 4 on the left and right sides of the partition 32 are swapped, and the remaining filter elements 4 are continued to be cleaned with reference to the above steps.

[0033] As an implementation method, the air pressure in the air outlet space 101 is greater than the atmospheric pressure, the filter element 4 is set as a filter bag, the bag opening of the filter bag is installed on the installation opening 331, and when there is a pressure difference between the upper and lower sides of the rotating plate 33, the bottom of the filter bag faces the low-pressure side;

[0034] The dust cleaning device comprises: a guide rail 51 and two squeezing assemblies 52, and a second driving mechanism 53; the guide rail 51 is horizontally installed on the side wall of the dust cleaning space 103; after the valve 34 is closed, the filter bag is located between the two squeezing assemblies 52, the squeezing assembly 52 comprises a support seat 521, a first squeezing roller 522, a sliding seat 523, a second squeezing roller 524 and a first driving mechanism 525, the first squeezing roller 522 is installed on the upper side of the support seat 521, and can clamp the bag mouth of the filter bag, the support seat 521 is slidably connected to the guide rail 51 and extends vertically, the sliding seat 523 and the first driving mechanism 525 are both arranged on the support seat 521, the first driving mechanism 525 can drive the sliding seat 523 to slide up and down along the support seat 521, the second squeezing roller 524 is installed on the sliding seat 523 and is lower than the first squeezing roller 522, and the second squeezing roller 524 can clamp the filter bag; the second driving mechanism 53 can drive the two squeezing assemblies 52 to approach or move away from each other.

[0035] Through the above arrangement, firstly, the efficiency of dust removal can be improved; secondly, dust can be prevented from entering the air outlet space 101 during cleaning.

[0036] In the present application, the air pressure in the air outlet space 101 is greater than the atmospheric pressure. Specifically, the air pressure in the air outlet space 101 can be made greater than the atmospheric pressure by reducing the diameter of the air outlet 312. The filter bag is basically cylindrical and has a large surface area, which improves the filtration efficiency. The material of the filter bag is relatively soft. When the air pressure on the upper side is greater than the air pressure on the next side, the filter bag extends vertically downward to the lower side of the rotating plate 33. When the air pressure on the lower side is greater than the air pressure on the upper side, the filter bag extends vertically upward to the upper side of the rotating plate 33. See Figure 2 The guide rails 51 are installed on the inner walls on both sides of the cleaning space 103. Each extrusion assembly 52 is provided with two support seats 521. The support seats 521 support both ends of the first extrusion roller 522 and the second extrusion roller 524 to improve the stability of the first extrusion roller 522 and the second extrusion roller 524. The two guide rails 51 and the two extrusion assemblies 52 form a rectangular structure, and the filter bag can enter the rectangular structure after extending downward.

[0037] When dust removal is performed by the dust collector of this application, refer to Figure 1 , all filter bags extend upward to the upper side of the rotating plate 33 to filter the air, and the dust in the air is retained on the inner side of the filter bags; when removing dust, the valve 34 is closed, and the cover plate 35 is opened. The air pressure in the dust cleaning space 103 is basically relative to the atmospheric pressure, and the air pressure in the air outlet space 101 is greater than the air pressure in the dust cleaning space 103. The filter bags corresponding to the dust cleaning space 103 extend downward into the dust cleaning space 103 and are located between the extrusion components 52, see Figure 3 The filter bag is turned over so that the dust on it is turned to the outside of the filter bag. At this time, the first squeezing roller 522 and the second squeezing roller 524 are close to the bag opening of the filter bag; see Figure 4 The second driving mechanism 53 drives the two squeezing assemblies 52 to approach each other. Specifically, the support seat 521 approaches the filter bag along the guide rail 51, and the support seat 521 drives the first squeezing roller 522 and the second squeezing roller 524 to approach the filter bag. Finally, the two first squeezing rollers 522 clamp the bag opening of the filter bag, and the two second squeezing rollers 524 clamp the filter bag. The filter bag forms an air bag at the lower side of the second squeezing roller 524; see Figure 5The first driving mechanism 525 drives the sliding seat 523 to move downward along the supporting seat 521, and the second squeezing roller 524 is locked on the supporting seat 521. The second squeezing roller 524 slides downward along the filter bag to push down the dust on the surface of the filter bag. The second squeezing roller is basically cylindrical, which can prevent the second squeezing roller 524 from damaging the surface of the filter bag. During the movement of the second squeezing roller 524, the second squeezing roller 524 brings down part of the dust on the surface of the filter bag. On the other hand, when the second squeezing roller 524 moves downward, the volume of the air bag decreases, and the air in the air bag enters the dust cleaning space 103 through the filter bag, and reversely flushes the dust on the surface of the filter bag, helping the dust to fall off the surface of the filter bag; since the first squeezing roller 522 clamps the bag opening of the filter bag, the air in the air outlet space 101 basically does not enter the filter bag. After the second squeezing roller 524 moves downward, the filter bag is in a deflated state, see Figure 5 The second drive mechanism 53 drives the two extrusion assemblies 52 to separate quickly, see Figure 6 The air in the air outlet space 101 enters the shrunken filter bag through the installation port 331. The filter bag is filled with air and expands. The dust on the surface of the filter bag is vibrated outward, which further helps the dust on the surface of the filter bag to fall off. The first driving mechanism 525 drives the sliding seat 523 to move upward along the supporting seat 521 to the upper end, and then repeats the above steps to squeeze and clean the filter bag for many times. After the cleaning is completed, the second driving mechanism 53 drives the two squeezing components 52 to separate, and the squeezing component 52 will filter After the bags are loosened, the cover plate 35 is closed and the valve 34 is opened. After the air in the air intake space 102 enters the cleaning space 103 through the through hole 321, the air pressure in the cleaning space 103 increases, causing the corresponding filter bags to extend upward to the upper side of the rotating plate 33, the filter bags are turned over again, and the dust collector returns to the initial state for dust removal; at this time, all the filter bags extend upward, and when the rotating plate rotates, the filter bags will not interfere with the partition, and the other filter bags can be rotated to the upper side of the cleaning space for the next round of cleaning.

[0038] The existing dust collector uses an up and down vibration method to clean dust. This method easily causes the dust on the filter bag to vibrate upward toward the air outlet 312, thereby reducing the air quality of the air output from the air outlet 312. In the present application, on the one hand, the second squeezing roller is used to squeeze the filter bag for cleaning, which makes the cleaning more gentle and less likely to damage the filter bag. On the other hand, when squeezing air, the air flow flows outward, so that the dust falls strictly outward. On the other hand, when the filter bag expands, the dust on the surface of the filter bag is basically only subjected to outward vibration, further preventing dust from entering the air outlet space 101. Finally, after the filter bag expands, since the air pressure in the air intake space 102 is greater than the air pressure in the cleaning space 103, the air in the air intake space 102 will pass through the filter bag and enter the cleaning space 103, and the air flow passing through the filter bag will also further cause the dust to fall into the cleaning space 103.

[0039] As an implementation method, the first squeezing roller 522 is close to the installation opening 331, and the up and down sliding stroke of the sliding seat 523 is greater than the length of the filter bag.

[0040] Through the above arrangement, the movement length of the second squeezing roller 524 is increased, and the cleaning quality is improved.

[0041] In the present application, when cleaning, when the sliding seat 523 moves to the lowermost end, the second squeezing roller 524 leaves the filter bag from the lower end to squeeze out almost all the air in the airbag, and the second squeezing roller 524 passes almost the entire filter bag, thereby improving the cleaning effect. Figure 5 .

[0042] As an implementation method, the first driving mechanism 525 includes: a screw 5251 and a first motor 5252; the screw 5251 is connected to one side of the support seat 521 in parallel rotation, and the screw 5251 is threadedly connected to the sliding seat 523; the first motor 5252 is installed on the support seat 521 and is transmission-connected to the screw 5251.

[0043] Through the above arrangement, the first motor 5252 drives the sliding seat 523 to move up and down through the screw rod 5251.

[0044] In the present application, both ends of the screw 5251 can be rotatably connected to one side of the support seat 521 through a connecting plate, and the first motor 5252 is installed at the upper end of the support seat 521. When the first motor 5252 drives the screw 5251 to rotate, the screw 5251 and the sliding seat 523 rotate relative to each other, and the sliding seat 523 moves upward or downward along the axis of the screw 5251.

[0045] As an implementation method, the second driving mechanism 53 includes: a second motor (not shown in the figure), a gear 532 and a rack 533; the second motor is installed on the housing 31; the gear 532 is transmission-connected to the second motor; the upper and lower sides of the gear 532 are horizontally meshed with racks 533, one of the racks 533 is fixedly connected to the support base 521 of one of the extrusion components 52, and the other rack 533 is fixedly connected to the support base 521 of the other end extrusion component 52.

[0046] Through the above arrangement, the second motor drives the two extrusion assemblies 52 to move closer to or away from each other through the gear 532 and the rack 533 .

[0047] In the present application, when the second motor drives the gear 532, the racks 533 on the upper and lower sides of the gear 532 move in opposite directions, so that the corresponding two extrusion assemblies 52 move closer to each other or farther away from each other.

[0048] As an implementation method, the rotating device 36 is configured as a third motor, the third motor is installed at the bottom of the shell 31, and a rotating groove is provided in the partition 32 that passes through the upper and lower sides of the partition 32. The output shaft of the motor passes through the rotating groove and is connected to the rotating plate 33.

[0049] In the present application, the third motor is configured as a servo motor. The servo motor has the advantages of high rotation accuracy and controllable rotation angle, and can strictly control the rotation angle of the rotating plate 33 .

[0050] As an implementation, there are two mounting openings 331 symmetrically disposed on opposite sides of the partition 32 , and the air inlet 311 is disposed at the bottom of the air inlet space 102 and faces one of the mounting openings 331 .

[0051] Through the above arrangement, the air output from the air inlet 311 can move quickly toward the filter bag.
