[0037] An embodiment of the present invention provides a dust cup assembly for use in a vacuum cleaner, such as... Figure 1 to Figure 6 As shown, the device includes a cyclone separator 100, a drive mechanism 200, a dust collection cup 610, and a cleaning mechanism 300. The cyclone separator 100 is configured to be detachably or non-detachably fixed inside the dust collection cup 610. The cyclone separator 100 has an annular filter wall 110. The drive mechanism 200 is located radially outside the filter wall 110. The cleaning mechanism 300 is located between the filter wall 110 and the drive mechanism 200, and is fitted onto the filter wall 110. The drive mechanism 200 is controlled to move, which in turn drives the cleaning mechanism 300 to move back and forth axially. The cleaning mechanism 300 moves back and forth linearly along the axial direction of the cyclone separator 100 on the outer peripheral surface of the cyclone separator 100. The cleaning mechanism 300 scrapes the outer peripheral surface of the filter wall 110 to remove the dirt attached to the filter wall 110. The dirt can be hair or other filamentous materials, paper scraps, etc.

[0038] The dust cup assembly, the radial driving mechanism 200 is arranged outside the filter wall 110, the cleaning mechanism 300 is arranged between the filter wall 110 and the driving mechanism 200, and the cleaning mechanism 300 is arranged on the outer circumferential surface of the filter wall 110. The driving mechanism 200 is controlled to drive the cleaning mechanism 300 to move reciprocatingly in the axial direction (i.e., reciprocatingly up and down), and the cleaning mechanism 300 moves reciprocatingly in a straight line along the axial direction of the cyclone separator 100 on the outer circumferential surface of the cyclone separator 100. The cleaning mechanism 300 reciprocatingly scrapes the outer circumferential surface of the filter wall 110 during the reciprocating movement, and effectively removes the dirt attached to the outer circumferential surface of the filter wall 110. The dirt removal method is simple, convenient, and easy to operate, and the application to the dust collector solves the problem of the rapid decrease of the suction force of the dust collector caused by the blockage of the cyclone separator 100 by hair and other filamentary materials, and the dirt on the outer circumferential surface of the cyclone separator 100 can be removed at any time, so that the user has a better experience of using the dust collector.

[0039] For example, as shown in Figure 3 to Figure 6 The cyclone separator 100 is arranged in the form of a ring-shaped metal mesh, and the metal can be stainless steel, alloy, aluminum, etc., which can achieve the purpose of the application, and the design idea is not deviated from the application, and will not be described here again, which should be within the protection scope of the application.

[0040] In an exemplary embodiment (not shown in the scheme), the driving mechanism is arranged in the form of a driving arm, the driving arm is arranged in parallel with the axis of the cyclone separator (i.e., the driving arm is arranged vertically), and the driving arm can move reciprocatingly in a straight line along the axial direction of the cyclone separator. The cleaning mechanism is connected to the driving arm, and the driving arm moves reciprocatingly in the axial direction, thereby driving the cleaning mechanism to move reciprocatingly in a straight line on the outer circumferential surface of the filter wall, so as to reciprocatingly scrape the outer circumferential surface of the filter wall and effectively remove the dirt attached to the outer circumferential surface of the filter wall.

[0041] The lower end of the driving arm can be arranged to be fixed with a driving ring, the driving ring is arranged to be movably in the axial direction outside the cyclone separator, and the cleaning mechanism is arranged in the form of a cleaning ring made of silica gel or rubber material, which is less likely to attach and adhere to hair and other filamentary materials. The cleaning ring is arranged to be fixed on the driving ring, and the driving ring drives the cleaning ring to move reciprocatingly in the axial direction, thereby avoiding the cleaning ring from being twisted, deformed, and skewed during the movement, and affecting the dirt removal quality. The cleaning ring can be fixed on the driving ring by bonding, or can be fixed on the driving ring by screw locking, which can achieve the purpose of the application, and the design idea is not deviated from the application, and will not be described here again, which should be within the protection scope of the application.

[0042] The driving ring can be integrally formed with the driving arm, or the driving ring can be separately connected with the driving arm, such as clamping connection, screw connection, etc. The above can achieve the purpose of the application, and the design idea is not deviated from the application, and will not be repeated here, which should be within the protection scope of the application.

[0043] The dust cup assembly further comprises a secondary separator and a motor assembly. The cyclone separator is located in the dust cup and assembled with the motor assembly through the secondary separator. The open end of the dust cup is connected to the lower end of the secondary separator. The outer side of the secondary separator is provided with a guide groove arranged in an up-down direction. The driving arm is installed in the guide groove, and the guide groove guides the driving arm when the driving arm moves up and down. The upper end of the driving arm has a driving column extending radially outward from the guide groove, which is used for the user to operate the driving arm to move up and down. A sealing ring can be arranged on the outer periphery of the driving ring. The guide groove is located above the sealing ring, and the sealing ring is in sealing cooperation with the inner side of the dust cup, thereby avoiding the overflow of dirt in the dust cup. When applied to a vacuum cleaner, the main body covers the guide groove to hide the second driving member, preventing dust from entering the guide groove. Therefore, the second driving member can smoothly slide up and down for a long time.

[0044] In another exemplary embodiment, as shown in Figure 3 to Figure 6 The driving mechanism 200 is provided with a first driving member 210 capable of moving up and down along the axial direction of the cyclone separator 100 and a second driving member 220 capable of moving up and down along the axial direction of the cyclone separator 100. The first driving member 210 is located above the second driving member 220. The first end of the second driving member 220 is adjacent to the second end of the first driving member 210, and the first end of the second driving member 220 is in transmission cooperation with the second end of the first driving member 210. The first end of the first driving member 210 is away from the second end of the second driving member 220, and the cleaning mechanism 300 is fixedly connected to the second end of the second driving member 220. The first end of the first driving member 210 is the upper end of the first driving member 210, and the second end of the first driving member 210 is the lower end of the first driving member 210. The first end of the second driving member 220 is the upper end of the second driving member 220, and the second end of the second driving member 220 is the lower end of the second driving member 220.

[0045] As shown in Figure 3 to Figure 6 The first driving member 210 can be a metal member, and the second driving member 220 can also be a plastic member. The above can achieve the purpose of the application, and the design idea is not deviated from the application, and will not be repeated here, which should be within the protection scope of the application.

[0046] As shown in Figure 3 to Figure 6As shown in the figure, the driving mechanism 200 further comprises a second elastic member 240 for resetting, which is arranged to cooperate with the second driving member 220, and the second driving member 220 is reset by the second elastic member 240 after being actuated. The second elastic member 240 can be a coil spring and the like.

[0047] As shown in the figure, Figure 5 and Figure 6 the side of the first end of the second driving member 220 is arranged to have a cooperating portion 221 radially protruding, which protrudes towards the side of the first driving member 210, the side of the second end of the first driving member 210 has a pressing portion 211 protruding, which protrudes towards the side of the second driving member 220, and the pressing portion 211 is axially above the cooperating portion 221, and the cleaning mechanism 300 is below the cooperating portion 221. The lower side of the pressing portion 211 is further arranged to abut against the upper side of the cooperating portion 221.

[0048] As shown in the figure, Figure 5 and Figure 6 axially, the second elastic member 240 is arranged between the cleaning mechanism 300 and the cooperating portion 221 and is sleeved on the second driving member 220, and the second elastic member 240 presses the cooperating portion 221 upwards, so as to realize the upward resetting of the second driving member 220 after being moved downwards. Of course, the second elastic member 240 can also be arranged above the second driving member 220, and the lower end of the second elastic member 240 pulls the second driving member 220 upwards, so as to realize the upward resetting of the second driving member 220 after being moved downwards, which also achieves the purpose of the present application, and the design idea is the same, which will not be described here again, and should also belong to the protection scope of the present application. Moreover, the number of the second elastic member 240 can be one, two or three, etc., which can be reasonably set by the person skilled in the art according to the needs, and will not be limited here, and should all belong to the protection scope of the present application.

[0049] As shown in the figure, Figure 5 and Figure 6 the driving mechanism 200 further comprises a first elastic member 230 for resetting, which is arranged to cooperate with the first driving member 210, and the first driving member 210 is reset by the first elastic member 230 after being actuated. The first elastic member 230 can be a coil spring and the like.

[0050] As shown in the figure, Figure 5 and Figure 6As shown, the first driving member 210 is arranged axially between the second driving member 220 and the first elastic member 230, that is, the first elastic member 230 is above the first driving member 210, the first elastic member 230 pulls the first driving member 210 upward, and after the first driving member 210 is driven to move downward, the first elastic member 230 controls the first driving member 210 to move upward to reset. Of course, the first elastic member 230 can also be arranged below the first driving member 210, and the first driving member 210 presses the first elastic member 230 downward. After the first driving member 210 is driven to move downward, the first elastic member 230 controls the first driving member 210 to move upward to reset, which can also achieve the purpose of the present application, and the design idea is not deviated from the present application, which will not be repeated here and should be within the protection scope of the present application.

[0051] Of course, the lower end of the first driving member 210 and the upper end of the second driving member 220 can also be connected by a radial insertion method, the lower end of the first driving member 210 and the upper end of the second driving member 220 can also be connected by a screw locking method, and the lower end of the first driving member 210 and the upper end of the second driving member 220 can also be connected by a gluing method, all of which can achieve the purpose of the present application, and the design idea is not deviated from the present application, which will not be repeated here and should be within the protection scope of the present application.

[0052] For example, as shown in the drawings, Figure 3 to Figure 6 The cleaning mechanism 300 is arranged as a cleaning ring made of silica gel or rubber, the lower end of the second driving member 220 is provided with a mounting ring 222, the mounting ring 222 is arranged to be axially movably sleeved on the outer circumferential surface of the filter wall 110, and the cleaning ring is arranged to be fixed on the mounting ring 222. The mounting ring 222 moves axially reciprocatingly with the cleaning ring, and the cleaning ring is less likely to be twisted, deformed and skewed, so that the dirt on the outer circumferential surface of the cyclone separator 100 is removed more effectively, and the cleaning ring made of silica gel or rubber is less likely to adhere to hair and other filamentous materials.

[0053] Of course, the cleaning mechanism 300 can also be arranged as a ring-shaped brush, a scraper or the like, which can also achieve the purpose of the present application, and the design idea is not deviated from the present application, which will not be repeated here and should be within the protection scope of the present application.

[0054] The mounting ring 222 and the second driving member 220 can be an integral structure, or the mounting ring 222 and the second driving member 220 can be a split structure, such as a clamping connection, a screw connection or the like, all of which can achieve the purpose of the present application, and the design idea is not deviated from the present application, which will not be repeated here and should be within the protection scope of the present application.

[0055] In an exemplary embodiment, as shown in the drawings, Figure 3 to Figure 6As shown, the dust cup assembly further comprises a secondary collector 400, the cyclone separator 100 is arranged in a cylindrical barrel shape, the secondary collector 400 is arranged to be fixedly installed at the second end of the cyclone separator 100 and communicates with the inside of the cyclone separator 100, the dirt entering the cyclone separator 100 will fall into the secondary collector 400 under the action of gravity and be collected at the inner bottom of the secondary collector 400. The first end of the cyclone separator 100 is the upper end, and the second end of the cyclone separator 100 is the lower end. The secondary collector 400 can be designed as a barrel structure with a bottom plate. The secondary collector 400 can also be designed as a barrel structure without a bottom plate, at this time, the lower end of the secondary collector 400 needs to be arranged to abut against the bottom wall 611 of the dust cup of the dust collector to be closed, when the dirt in the dust cup 610 of the dust collector is cleaned, the lower end of the secondary collector 400 is also opened, and the dirt in the secondary collector 400 is also cleaned out.

[0056] For example, as shown in Figure 3 to Figure 6 As shown, the outer peripheral surface of the upper end of the secondary collector 400 protrudes a dirt blocking lip 410 extending downwardly and obliquely, the dirt blocking lip 410 blocks the dirt deposited on the inner bottom of the dust cup 610 outside the secondary collector 400 from flying upwardly, the dust cup assembly applied to the dust collector can better ensure the dust collection effect of the dust collector. The dirt scraped off the outer surface of the cyclone separator 100 falls on the dirt blocking lip 410 and slides downwardly along the upper side of the dirt blocking lip, and the dirt blocking lip 410 is less likely to store dirt.

[0057] The dirt blocking lip 410 can be a hard structure. The dirt blocking lip 410 can also be a flexible mechanism, at this time, the axial stroke of the cleaning mechanism 300 moving downwardly can be increased, or the axial height of the cyclone separator 100 can be shortened, when the cleaning mechanism 300 moves to the lowermost limit position, the mounting ring 222 extrudes the dirt blocking lip 410 downwardly, so that the dirt blocking lip 410 is twisted and deformed downwardly, so that the dirt scraped off the cyclone separator 100 will directly fall below the dirt blocking lip 410 and finally fall on the bottom wall 611 of the dust cup outside the secondary collector 400, and the dirt blocking lip 410 is less likely to store dirt.

[0058] For example, as shown in Figure 5 and Figure 6 The first driving member 210 is arranged as a driving rod arranged in an up-down direction, and the second driving member 220 is also arranged as a driving rod arranged in an up-down direction.

[0059] The dust collecting cup 610 has an installation cavity inside, the cyclone separator 100 is located in the installation cavity, and the second driving member 220 is located above the installation cavity. The cyclone separator 100 divides the installation cavity into a cylindrical separation cavity and a circular ring-shaped collection cavity. The collection cavity is wrapped outside the separation cavity. The dirt filtered by the cyclone separator 100 falls into the collection cavity. The air filtered by the cyclone separator 100 enters the separation cavity and is finally discharged to the outside. A stop surface 700 is arranged on the upper side of the collection cavity. The cleaning mechanism 300 is located below the stop surface 700. The lower end of the second driving member 220 passes through the stop surface 700 downward and is connected with the cleaning mechanism 300. The second elastic member 240 is sleeved on the second driving member 220. The lower end of the second elastic member 240 is pressed downward on the stop surface 700. The upper end of the second elastic member 240 is pressed upward on the upper end of the second driving member 220 (i.e. the upper end of the second elastic member 240 is pressed upward on the matching part 221 of the upper end of the second driving member 220). The bottom wall 611 of the dust collecting cup is hingedly installed (of course, the dust collecting cup 610 can also be opened and closed by the whole disassembly and installation). Whether the dust collecting cup 610 is opened or closed, the driving mechanism 200 can drive the cleaning mechanism 300 to reciprocatingly move along the axial direction of the cyclone separator 100 to reciprocatingly clean the outer peripheral surface of the cyclone separator 100. Compared with the reciprocating cleaning of the outer peripheral surface of the cyclone separator 100 when the dust collecting cup 610 is opened, the dirt scraped off when the dust collecting cup 610 is closed will not be scattered to the outside. When the dirt in the dust collecting cup 610 needs to be removed, the dust collecting cup 610 can be directly opened.

[0060] For example, with reference to Figure 1 to Figure 6As shown, the side wall of the dust collecting cup 610 is provided with a dust collecting inlet, the dust collector has a main body 500, the lower end of the main body 500 is provided with a suction pipe 800, the dust collecting inlet is connected with the suction pipe 800, that is, no matter when the bottom wall 611 of the dust collecting cup is opened or closed, the driving mechanism 200 can drive the cleaning mechanism 300 to reciprocatingly move along the axial direction of the cyclone separator 100, so as to realize the reciprocating cleaning of the outer peripheral surface of the cyclone separator 100; the dust cup assembly further comprises: a cyclone separator 900 and a motor assembly 620, the motor assembly 620 is arranged above the dust collecting cup 610, the cyclone separator 100 is arranged in the dust collecting cup 610, the first end of the cyclone separator 100 is arranged to be matched with the motor assembly 620 through the secondary separator 900, the upper end of the dust collecting cup 610 is sleeved with the lower end of the secondary separator 900, the inner region of the (barrel-shaped) auxiliary collector 400, the inner region of the cyclone separator 100, the motor assembly 620 and the bottom wall 611 of the dust collecting cup jointly form a separation cavity, the dirt (generally dust) entering the cyclone separator 100 finally falls to the bottom wall of the separation cavity for collection, the region outside the cyclone separator 100, the region outside the auxiliary collector 400 and the inner region of the dust collecting cup 610 jointly form a collection cavity, the dirt (generally hair, paper scraps and particulate matter) filtered out by the cyclone separator 100 falls to the bottom wall of the collection cavity, the second driving member 220 is installed on the side wall of the secondary separator 900; and an air outlet assembly 630, the air outlet assembly 630 is arranged outside the dust collecting cup 610 and is arranged to be installed on the top of the motor assembly 620, the air filtered out by the cyclone separator 100 enters the motor assembly 620 after entering the separation cavity and the secondary separator 900, and finally is discharged to the outside from the air outlet assembly 630. The peripheral wall of the air outlet assembly 630 is provided with an air outlet.
