The dust cup assembly and the dust collector main machine are detachably connected. The dust cup assembly 100 comprises a cup body 110, a dust cup filter 120 and a leak-proof limiting member 130.
[0031] The cup body 110 has a docking end 110a for docking with the main machine of the vacuum cleaner, and the cup body 110 comprises a filter mounting cavity 111 arranged at the docking end 110a. The dust cup filter 120 is detachably mounted in the filter mounting cavity 111. The anti-missing limiting piece 130 is mounted on the cup body 110 and located at the circumferential edge of the filter mounting cavity 111, and the anti-missing limiting piece 130 comprises an abutting portion 1311 extending along the axial direction of the cup body 110.
[0032] As Figure 2 In the embodiment, when the dust cup filter 120 is mounted in the filter mounting cavity 111, the abutting portion 1311 can be pressed to the outside of the filter mounting cavity 111. As Figure 3 When the dust cup filter 120 is separated from the filter mounting cavity 111, the abutting portion 1311 extends into the filter mounting cavity 111 and can abut against the main machine of the vacuum cleaner to block the docking of the dust cup assembly 100 and the main machine of the vacuum cleaner.
[0033] The dust cup assembly 100 according to the embodiment of the present application can be detachably connected with the main machine of the vacuum cleaner. The dust cup assembly 100 comprises a cup body 110, a dust cup filter 120 and an anti-missing limiting piece 130. The cup body 110 comprises a docking end 110a for docking with the main machine of the vacuum cleaner, and a filter mounting cavity 111 is arranged at the docking end 110a. The dust cup filter 120 is detachably mounted in the filter mounting cavity 111. The anti-missing limiting piece 130 is located at the circumferential edge of the filter mounting cavity 111. As Figure 3 When the dust cup assembly 100 and the main machine of the vacuum cleaner are ready to be assembled, if the dust cup filter 120 is forgotten to be mounted in the dust cup assembly 100, the abutting portion 1311 of the anti-missing limiting piece 130 will extend into the filter mounting cavity 111, and at this time the abutting portion 1311 abuts against the main machine of the vacuum cleaner when the dust cup assembly 100 is assembled with the main machine of the vacuum cleaner, thereby blocking the docking of the dust cup assembly 100 and the main machine of the vacuum cleaner, and realizing the missing reminding of the dust cup filter 120. As Figure 2 When the dust cup filter 120 is mounted in the filter mounting cavity 111, the dust cup filter 120 can press the abutting portion 1311 to the outside of the filter mounting cavity 111, and at this time the abutting portion 1311 no longer interferes with the main machine of the vacuum cleaner when the dust cup assembly 100 is assembled with the main machine of the vacuum cleaner, so that the dust cup assembly 100 and the main machine of the vacuum cleaner can be smoothly docked and assembled. The above-mentioned embodiment can realize the missing prevention of the dust cup filter 120 by arranging the anti-missing limiting piece 130 at the circumferential edge of the filter mounting cavity 111, so that the missing prevention of the dust cup filter 120 is realized by a relatively simple and reliable structure, and the cost of realizing the missing prevention function is reduced while realizing the missing prevention of the dust cup filter 120.
[0034] In some embodiments, the anti-missing limiting piece 130 has a limiting state and an unlocking state. As Figure 3, dust cup filter 120 is out of the filter mounting cavity 111, the anti-leakage assembly limiting piece 130 is in the limiting state, at this time the abutting portion 1311 of the anti-leakage assembly limiting piece 130 extends into the filter mounting cavity 111, and the dust cup assembly 100 is assembled with the dust collector main machine, the abutting portion 1311 is in abutment with the dust collector main machine, interferes with the relative movement of the dust collector main machine and the dust cup assembly 100, and blocks the butt joint of the dust cup assembly 100 and the dust collector main machine. As Figure 2 , after the dust cup filter 120 is assembled into the filter mounting cavity 111, the anti-leakage assembly limiting piece 130 is in the unlocking state, the abutting portion 1311 of the dust cup filter 120 is extruded to the outside of the filter mounting cavity 111, and the dust cup assembly 100 can be smoothly butted with the dust collector main machine.
[0035] As Figures 1 to 3 , in some embodiments, the anti-leakage assembly limiting piece 130 includes a movable piece 131 and an elastic reset piece 132. The movable piece 131 includes an abutting portion 1311, and the movable piece 131 is movably installed on the cup body 110. The movable piece 131 has a first position and a second position. As Figure 3 , the movable piece 131 is moved to the first position so that the abutting portion 1311 extends into the filter mounting cavity 111. As Figure 2 , the movable piece 131 is moved to the second position so that the abutting portion 1311 is located outside the filter mounting cavity 111. The elastic reset piece 132 elastically connects the movable piece 131 and the cup body 110, and the elastic reset piece 132 is used to reset the movable piece 131 to the first position.
[0036] In the above embodiment, the anti-leakage assembly limiting piece 130 includes the movable piece 131 and the elastic reset piece 132, and the anti-leakage assembly limiting function of the dust cup filter 120 is realized through a relatively simple and reliable structure. Specifically, the movable piece 131 is movably installed on the cup body 110, and the movable piece 131 is moved to the first position and the second position to realize the switching of the anti-leakage assembly limiting piece 130 between the limiting state and the unlocking state. The elastic reset piece 132 is used to reset the movable piece 131 to the first position, so that the default state of the anti-leakage assembly limiting piece 130 is the limiting state, thereby ensuring that the anti-leakage assembly limiting piece 130 is in the limiting state when the dust cup filter 120 is not assembled into the filter mounting cavity 111, and the anti-leakage assembly limiting function of the dust cup filter 120 is guaranteed.
[0037] The specific installation mode of the movable piece 131 movably installed on the cup body 110 can be various, in some embodiments, the movable piece 131 can be rotatably installed on the cup body 110, in some embodiments, the movable piece 131 can be slidably installed on the cup body 110, and in some embodiments, the movable piece 131 can also be installed on the cup body 110 in a more complex installation mode, for example, an installation mode combining rotary installation and sliding installation.
[0038] As Figures 1 to 3In one example, the movable piece 131 is rotatably installed on the cup body 110.
[0039] As Figures 1 to 3 In some embodiments, the movable piece 131 is rotatably installed on the cup body 110 through the rotating shaft piece 133, and the elastic reset piece 132 includes a torsion spring coaxially arranged with the rotating shaft piece 133.
[0040] In the above embodiments, the movable piece 131 is rotatably installed on the cup body 110 through the rotating shaft piece 133, and the reset of the movable piece 131 to the first position is achieved by the torsion spring coaxially arranged with the rotating shaft piece 133, so that the overall structure of the anti-leakage assembly limiting piece 130 is more compact, the space occupation of the anti-leakage assembly limiting piece 130 in the dust cup assembly 100 is smaller, the integration of the anti-leakage assembly limiting piece 130 in the dust cup assembly 100 is facilitated, and the appearance structure of the cup body 110 of the dust cup assembly 100 is also facilitated to be optimized.
[0041] Figure 4 It is a perspective exploded view of another embodiment of the dust cup assembly of the utility model. As Figure 4 In some embodiments, the anti-leakage assembly limiting piece 130 includes a movable piece 131 and an elastic reset piece 132. The movable piece 131 includes an abutting portion 1311. The movable piece 131 has a first position and a second position. The movable piece 131 is moved to the first position so that the abutting portion 1311 extends into the filter mounting cavity 111. The movable piece 131 is moved to the second position so that the abutting portion 1311 is located outside the filter mounting cavity 111. The elastic reset piece 132 is used to reset the movable piece 131 to the first position.
[0042] As Figure 4 In some embodiments, the movable piece 131 is rotatably installed on the cup body 110 through the rotating shaft piece 133, and the movable piece 131 further includes a connecting portion 1312. The connecting portion 1312 and the abutting portion 1311 are respectively located on opposite sides of the rotating shaft piece 133, and the connecting portion 1312 is connected with the elastic reset piece 132. At this time, the elastic reset piece 132 is, for example, a tensile spring or a compression spring. As Figure 5 In one example, the elastic reset piece 132 is a tensile spring. When the dust cup filter 120 is not installed in the filter mounting cavity 111, the tensile spring is contracted, the connecting portion 1312 is pulled to move so that the movable piece 131 rotates around the rotating shaft piece 133, the abutting portion 1311 at the other end of the movable piece 131 extends into the filter mounting cavity 111, and the abutting portion 1311 blocks the abutting of the dust cup assembly 100 and the main machine of the dust collector. After the dust cup filter 120 is installed in the filter mounting cavity 111, the sidewall of the dust cup filter 120 abuts against the movable piece 131 to make the movable piece 131 rotate, the tensile spring is stretched, and the dust cup filter 120 extrudes the abutting portion 1311 to the outside of the filter mounting cavity 111, so that the dust cup assembly 100 can be smoothly docked with the main machine of the dust collector.
[0043] AsFigure 1 Or Figure 4 In some embodiments, the cup body 110 further comprises a limiting side wall 112 located on the side of the leakage-preventing limiting member 130 away from the filter mounting cavity 111, and the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the first position or the second position. In some embodiments, the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the first position, and in other embodiments, the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the second position. For example, Figure 4 And Figure 5 For example, in another embodiment of the present application, the movable member 131 extends into the filter mounting cavity 111 when the movable member 131 is moved to the first position, wherein the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the first position. In one example, as shown in FIG. 1, the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the first position. Figure 5 When the movable member 131 is moved to the first position, the connecting portion 1312 abuts against the limiting side wall 112.
[0044] In the above embodiments, the limiting side wall 112 of the cup body 110 can abut against the limiting side wall 112 when the movable member 131 is moved to the first position or the second position, thereby providing a limiting effect and a protection effect on the movable member 131, and avoiding the abrasion of the movable member 131 caused by the direct exposure of the movable member 131 to the cup body 110.
[0045] For example, Figure 4 And Figure 5 In some embodiments, the limiting side wall 112 is provided with a limiting protrusion 1121 protruding towards the filter mounting cavity 111, and the movable member 131 abuts against the limiting protrusion 1121 when the movable member 131 is moved to the first position or the second position. In some embodiments, the movable member 131 abuts against the limiting protrusion 1121 when the movable member 131 is moved to the first position. In other embodiments, the movable member 131 abuts against the limiting protrusion 1121 when the movable member 131 is moved to the second position. In one example, the movable member 131 abuts against the limiting side wall 112 when the movable member 131 is moved to the second position, for example, the abutting portion 1311 abuts against the limiting side wall 112 when the movable member 131 is moved to the second position. By providing the limiting protrusion 1121, on the one hand, the limiting side wall 112 can limit the movable member 131, and provide limiting for different positions of the movable member 131, and on the other hand, the limiting protrusion 1121 can further limit the movable member 131, for example, the movable member 131 abuts against the limiting protrusion 1121 when the movable member 131 is moved to the first position or the second position, thereby avoiding the direct abutment of the movable member 131 against the limiting side wall 112.
[0046] For example, Figure 4 And Figure 5In one example, the elastic reset member 132 is a tension spring, the connecting portion 1312 of the movable member 131 has a spring mounting hole, the limiting protrusion 1121 on the limiting side wall 112 has another spring mounting hole, the connecting portion 1312 and the limiting protrusion 1311 are respectively located on opposite sides of the rotating shaft member 133, and the elastic reset member 132 is connected between the two spring mounting holes. Of course, in other embodiments, the other spring mounting hole can also be provided on the limiting side wall.
[0047] In the above-mentioned example embodiments, the movable member 131 is rotationally mounted on the cup body 110, and in other embodiments, the movable member 131 can be mounted on the cup body 110 in other ways, for example, the movable member 131 is slidingly mounted on the cup body 110. In one example, when the movable member 131 is slidingly mounted on the cup body 110, the movable member 131 can move linearly relative to the cup body 110, for example, linearly along the radial direction relative to the cup body 110. When the dust cup filter 120 is not mounted in the filter mounting cavity 111, the movable member 131 is moved along the radial direction to make the abutting portion 1311 extend into the filter mounting cavity 111, thereby blocking the dust cup assembly 100 from being docked with the main machine of the vacuum cleaner. After the dust cup filter 120 is mounted in the filter mounting cavity 111, the side wall of the dust cup filter 120 abuts against the movable member 131 to move the movable member 131 along the radial direction away from the center of the filter mounting cavity 111, thereby extruding the abutting portion 1311 to the outside of the filter mounting cavity 111, and the dust cup assembly 100 can be smoothly docked with the main machine of the vacuum cleaner.
[0048] As Figure 1 or Figure 4 In some embodiments, the movable member 131 has a contact surface S1 that contacts the dust cup filter 120 in the second position, and the contact surface S1 is shaped to match the shape of part of the side surface of the dust cup filter 120.
[0049] In one example, the inner circumferential surface of the filter mounting cavity 111 is substantially a cylindrical surface, and the outer circumferential surface of the dust cup filter 120 is a cylindrical surface. At this time, the contact surface S1 is a circular arc surface and is shaped to match the shape of part of the side surface of the dust cup filter 120. When the dust cup filter 120 is mounted in the filter mounting cavity 111, the side surface of the dust cup filter 120 is shaped to match the contact surface S1, thereby being more closely fitted, and the stability of the mounting of the dust cup filter 120 in the filter mounting cavity 111 is ensured.
[0050] In some embodiments of the above examples, the anti-misinstallation limiting piece 130 includes a movable piece 131 and an elastic reset piece 132. The movable piece 131 is movable to the first position and the second position, so as to switch the anti-misinstallation limiting piece 130 between the limiting state and the unlocking state. The elastic reset piece 132 is configured to reset the movable piece 131 to the first position, so that the default state of the anti-misinstallation limiting piece 130 is the limiting state. In other embodiments, the anti-misinstallation limiting piece 130 is not limited to the anti-misinstallation function achieved by the movable piece 131 and the elastic reset piece 132. For example, in other embodiments, the anti-misinstallation limiting piece 130 is an elastic telescopic piece. The abutting portion 1311 is located at the telescopic end of the anti-misinstallation limiting piece 130, which is the end capable of extending into the filter mounting cavity 111. In the absence of external force, the anti-misinstallation limiting piece 130 is elongated to enter the filter mounting cavity 111, and the dust cup filter 120 is installed into the filter mounting cavity 111 to compress and shrink the anti-misinstallation limiting piece 130.
[0051] In one example, the anti-misinstallation limiting piece 130 is elastically deformable in the radial direction of the cup body 110. In the absence of external force, the anti-misinstallation limiting piece 130 is elongated to enter the filter mounting cavity 111 when the dust cup filter 120 is not installed into the filter mounting cavity 111. At this time, the abutting portion 1311 extends into the filter mounting cavity 111 to block the docking of the dust cup assembly 100 with the main cleaner. After the dust cup filter 120 is installed into the filter mounting cavity 111, the dust cup filter 120 compresses and shrinks the anti-misinstallation limiting piece 130, and the abutting portion 1311 is pressed to the outside of the filter mounting cavity 111, so that the dust cup assembly 100 can be smoothly docked with the main cleaner.
[0052] The utility model embodiment further provides a cleaning device, it includes dust catcher main machine and any preceding embodiment's dust cup assembly 100, dust cup assembly 100 and dust catcher main machine are detachable connection. Dust cup assembly 100 includes cup body 110, dust cup filter 120 and anti-misinstallation limiting piece 130. Cup body 110 has the docking end portion 110a for docking with dust catcher main machine, and cup body 110 includes the filter mounting cavity 111 arranged at the docking end portion 110a. Dust cup filter 120 is detachably installed in the filter mounting cavity 111. Anti-misinstallation limiting piece 130 is installed on cup body 110 and located at the circumferential edge of filter mounting cavity 111, and anti-misinstallation limiting piece 130 includes the abutting portion 1311 extending in the axial direction of cup body 110. Dust cup filter 120 is installed into the filter mounting cavity 111 to press the abutting portion 1311 to the outside of the filter mounting cavity 111, and after dust cup filter 120 leaves the filter mounting cavity 111, the abutting portion 1311 extends into the filter mounting cavity 111 and can abut against the dust catcher main machine to block the docking of the dust cup assembly 100 with the dust catcher main machine.
[0053] The anti-misassembly limiting piece 130 has a limiting state and an unlocking state. After the dust cup filter 120 leaves the filter mounting cavity 111, the anti-misassembly limiting piece 130 is in the limiting state, at which time the abutting portion 1311 of the anti-misassembly limiting piece 130 extends into the filter mounting cavity 111, and when the dust cup assembly 100 and the main machine of the vacuum cleaner are assembled, the abutting portion 1311 abuts against the main machine of the vacuum cleaner, interferes with the relative movement of the main machine of the vacuum cleaner and the dust cup assembly 100, and blocks the abutment of the dust cup assembly 100 and the main machine of the vacuum cleaner. After the dust cup filter 120 is assembled into the filter mounting cavity 111, the anti-misassembly limiting piece 130 is in the unlocking state, and the dust cup filter 120 extrudes the abutting portion 1311 to the outside of the filter mounting cavity 111, so that the dust cup assembly 100 can be smoothly abutted with the main machine of the vacuum cleaner.
[0054] The cleaning device according to the embodiment of the present application comprises a detachably connected main machine of a vacuum cleaner and a dust cup assembly 100.

The cup body 110 comprises an abutment end portion 110a for abutting with the main machine of the vacuum cleaner, and a filter mounting cavity 111 is arranged at the abutment end portion 110a. The dust cup filter 120 is detachably mounted in the filter mounting cavity 111. The anti-misassembly limiting piece 130 is arranged at the circumferential edge of the filter mounting cavity 111. When the mutually separated dust cup assembly 100 and the main machine of the vacuum cleaner are ready to be assembled, if the dust cup filter 120 is forgotten to be assembled in the dust cup assembly 100, the abutting portion 1311 of the anti-misassembly limiting piece 130 will extend into the filter mounting cavity 111, at which time the abutting portion 1311 abuts against the main machine of the vacuum cleaner when the dust cup assembly 100 and the main machine of the vacuum cleaner are assembled, blocks the abutment of the dust cup assembly 100 and the main machine of the vacuum cleaner, and realizes the misassembly reminding of the dust cup filter 120. After the dust cup filter 120 is assembled into the filter mounting cavity 111, the dust cup filter 120 can extrude the abutting portion 1311 to the outside of the filter mounting cavity 111, at which time the abutting portion 1311 does not interfere with the main machine of the vacuum cleaner when the dust cup assembly 100 and the main machine of the vacuum cleaner are assembled, and the dust cup assembly 100 and the main machine of the vacuum cleaner can be smoothly abutted and assembled. The above embodiment can realize the anti-misassembly of the dust cup filter 120 by arranging the anti-misassembly limiting piece 130 at the circumferential edge of the filter mounting cavity 111, and realizes the anti-misassembly function of the dust cup filter 120 by a relatively simple and reliable structure, and reduces the cost of realizing the anti-misassembly function while realizing the anti-misassembly of the dust cup filter 120.
