[0034] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0035] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0036] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0037] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0038] As shown in Figure 1, it can be understood that the dust cup assembly of the embodiment of the present application includes a cup body 101, a cup cover 102 and a switch mechanism 103. The cup body 101 can be used to place components such as a cyclone separator, a dust collection barrel and a filter. The cup body 101 has a cleaning port 104. The cup cover 102 is mounted on the cup body 101. The cup cover 102 can move relative to the cup body 101, thereby realizing the function of opening and closing the cleaning port 104. During operation, the dust enters the cyclone separator to separate the dust and gas, and passes through the filter to separate the coarse ash. The separated dust is collected in the dust collection barrel and the cup body 101. The switch mechanism 103 is mounted on the cup body 101. When the switch mechanism 103 is triggered, the cup cover 102 can be released. After the cup cover 102 is opened, the dust can fall from the cleaning port 104 and eventually flow out of the cup body 101.

[0039] It should be noted that the cleaning port 104 shown in FIG1 is located at the bottom of the cup body 101, and correspondingly, the cup cover 102 is also configured as a bottom cover. In other embodiments, the cleaning port 104 and the cup cover 102 can also be located on the circumference of the cup body 101. For example, the cleaning port 104 is located on the front side of the cup body 101, and in this case, the cup cover 102 is also located on the front side of the cup body 101.

[0040] As shown in Figure 1, it can be understood that the cup body 101 also has a mounting cavity 105, and the switch mechanism 103 is located in the mounting cavity 105. In one embodiment, the cup body 101 includes a first mounting portion 106, and the position of the cup body 101 near the cleaning port 104 is partially concave inward and partially convex outward, thereby forming the first mounting portion 106, and the mounting cavity 105 is formed in the first mounting portion 106. The switch mechanism 103 specifically includes a connecting rod 107 and a locking member 108. The locking member 108 is used to connect the cup cover 102. When the cup cover 102 closes the cleaning port 104, the locking member 108 provides a force on the cup cover 102, so that the cup cover 102 remains in the position of closing the cleaning port 104. The position of the cup cover 102 when closing the cleaning port 104 is defined as the first position. The connecting rod 107 is connected to the locking member 108. When an external force is applied to the connecting rod 107, the connecting rod 107 transmits a force to the locking member 108, prompting the locking member 108 to move, thereby releasing the force between the locking member 108 and the cup cover 102, and allowing the cup cover 102 to move away from the first position, thereby opening the cleaning port 104. The position of the cup cover 102 when the cleaning port 104 is opened is defined as the second position.

[0041] It should be noted that the first mounting portion 106 can be located inside the cup body 101 or outside the cup body 101 , and correspondingly, the switch mechanism 103 can also be located inside or outside the cup body 101 .

[0042] 1 to 3 , it can be understood that the connecting rod 107 includes a trigger portion 109 and a push portion 110. The trigger portion 109 abuts against the locking member 108, and the push portion 110 is located on the side of the trigger portion 109 away from the locking member 108. The push portion 110 is provided with a groove suitable for the size of a finger. A first opening 111 and a second opening 112 are provided on the cup body 101. Both the first opening 111 and the second opening 112 are connected to the mounting cavity 105. The first opening 111 is provided on the outer side of the peripheral wall of the cup body 101, and the push portion 110 is located near the first opening 111. The user can push the connecting rod 107 to move through the first opening 111. The second opening 112 is set on the end face of the cup body 101 facing the cup cover 102, and the trigger part 109 is exposed at the position of the second opening 112. When the dust cup assembly is placed in the base station 201, the release mechanism 202 of the base station 201 can push the trigger part 109 to move along the axial direction of the cleaning port 104, thereby prompting the locking part 108 to move, so that the cup cover 102 can move to the second position.

[0043] 2 , it can be understood that the dust cup assembly is located above the base station 201, and the cleaning port 104 is placed toward the base station 201. When the dust cup assembly is installed in the base station 201, the dust cup assembly as a whole moves along the axial direction of the cleaning port 104. A release mechanism 202 is provided in the base station 201. The release mechanism 202 can pass through the second opening 112 and abut against the trigger portion 109. As the dust cup assembly continues to descend, the release mechanism 202 pushes the trigger portion 109 to move, thereby pushing the locking member 108 to open the cleaning port 104. In addition, the user can also manually push the connecting rod 107 from the peripheral side of the cup body 101, thereby pushing the locking member 108 to open the cleaning port 104. Therefore, the locking member 108 of the embodiment of the present application can push the connecting rod 107 in two perpendicular directions, thereby pushing the locking member 108 to open the cleaning port 104.

[0044] 1 and 3 , it can be understood that, in one embodiment, a rotating protrusion 113 is provided in the middle of the locking member 108, which is rotatably connected to the cup body 101. A first hook 301 is provided at one end of the locking member 108, and the trigger 109 abuts against the other side of the locking member 108, that is, the side of the locking member 108 away from the cup lid 102. A second hook 302 is provided on the inner side of the cup lid 102, which engages with the first hook 301 to maintain the cup lid 102 in the position closing the cleaning port 104. When a user's finger pushes the pushing member 110, the pushing member 110 moves under the action of an external force, and the trigger 109 generates a downward force on the locking member 108, causing the locking member 108 to rotate clockwise as shown, thereby disengaging the first hook 301 from the second hook 302, allowing the cup lid 102 to move to the second position.

[0045] It should be noted that the first hook portion 301 may be a hook-shaped structure, i.e., having two parts that are perpendicular or nearly perpendicular to each other. The second hook portion 302, in addition to being a hook-shaped structure, also generally refers to any structure that can hook onto the first hook portion 301. For example, the second hook portion 302 may be a slot structure, into which the first hook portion 301 can be inserted, and the sidewalls and bottom wall of the slot structure are two perpendicular parts that can hook onto the first hook portion 301, thereby keeping the cup lid 102 in the closed position of the cleaning port 104.

[0046] It can be understood that a second reset member 114 is provided between the locking member 108 and the cup body 101. After the locking member 108 rotates, the second reset member 114 can prompt the locking member 108 to return to its original position. When the locking member 108 returns to its original position, the second reset member 114 can also provide a pre-tightening force to prevent the locking member 108 from automatically detaching from the cup cover 102.

[0047] In one embodiment, the second return member 114 can be a compression spring, one end of which is connected to the end of the lock member 108 away from the cup cover 102, and the other end is connected to the bottom wall of the mounting cavity 105. When the lock member 108 rotates to open the cup cover 102, the lock member 108 rotates in the clockwise direction shown in the figure, and the compression spring is compressed. After the force acting on the lock member 108 disappears, the elastic force of the compression spring prompts the lock member 108 to rotate in the opposite direction and return to its original position, making it easier to lock the cup cover 102 next time. In addition, the elastic force of the compression spring acts on the lock member 108, causing it to have a tendency to rotate counterclockwise, which is conducive to improving the reliability of the connection between the lock member 108 and the cup cover 102.

[0048] In one embodiment, the second return member 114 can also be a tension spring, one end of which is connected to the end of the lock member 108 close to the cup cover 102, and the other end is connected to the bottom wall of the mounting cavity 105. When the lock member 108 rotates to open the cup cover 102, the lock member 108 rotates in the clockwise direction shown in the figure, and the tension spring is stretched. After the force acting on the lock member 108 disappears, the elastic force of the tension spring prompts the lock member 108 to rotate in the opposite direction and return to its original position, making it easier to lock the cup cover 102 next time. In addition, the elastic force of the tension spring acts on the lock member 108, causing it to have a tendency to rotate counterclockwise, which is conducive to improving the reliability of the connection between the lock member 108 and the cup cover 102.

[0049] In one embodiment, the second return member 114 can also be a torsion spring, one end of which is connected to the locking member 108 and the other end is connected to the inner wall of the mounting cavity 105. When the locking member 108 rotates to open the cup cover 102, the locking member 108 rotates in the clockwise direction shown in the figure, and the torsion spring is torsionally deformed. After the force acting on the locking member 108 disappears, the elastic force of the torsion spring prompts the locking member 108 to rotate in the opposite direction and return to its original position, making it easier to lock the cup cover 102 next time. In addition, the elastic force of the torsion spring acts on the locking member 108, causing it to have a tendency to rotate counterclockwise, which helps to improve the reliability of the connection between the locking member 108 and the cup cover 102.

[0050] 1 and 3 , it can be understood that the locking member 108 is provided with a first guide portion 115, which is located on the side of the locking member 108 away from the cup cover 102, and the trigger portion 109 abuts against the first guide portion 115, and the first guide portion 115 guides the trigger portion 109 to move along a predetermined direction. Specifically, in the direction away from the cup cover 102, the distance between the outer surface of the first guide portion 115 and the axis of the cleaning port 104 gradually increases, that is, the closer the outer surface of the first guide portion 115 is to the interior of the cup body 101, the closer it is to the pushing portion 110. The pushing portion 110 is connected to the cup body 101, limiting the pushing portion 110 to move only in a direction parallel to the axial direction of the cleaning port 104, and not in a direction perpendicular to the axial direction of the cleaning port 104.

[0051] Specifically, as shown in FIG3 , the pushing portion 110 moves in the up-down direction. When the connecting rod 107 moves upward under the force of the user or the base station 201, the trigger portion 109 moves relatively from the lower end of the first guide portion 115 to the upper end of the first guide portion 115. Since the pushing portion 110 cannot move in a direction perpendicular to the axial direction of the cleaning port 104, during the upward movement of the pushing portion 110, the force applied to the locking member 108 generates a component force perpendicular to the first guide portion 115. This component force pushes the first guide portion 115 to rotate away from the pushing portion 110, thereby pushing the locking member 108 to rotate, thereby allowing the first hook portion 301 to rotate and disengage from the second hook portion 302, allowing the cup cover 102 to rotate downward to open the cleaning port 104. In the figure, the first guide portion 115 is a sloped structure, but the first guide portion 115 can also be set to a curved surface or other structural form.

[0052] It should be noted that in some other embodiments, when the locking member 108 is in the structural form shown in Figures 1 and 3, the pushing portion 110 can also be constructed in other structural forms. For example, the pushing portion 110 is connected to the cup body 101, limiting the pushing portion 110 to move only in a direction perpendicular to the axial direction of the cleaning port 104, and can directly push the locking member 108 to rotate, but cannot move in a direction parallel to the axial direction of the cleaning port 104. In this case, a second guide portion is provided on the connecting rod 107. As it moves away from the cup cover 102, the distance between the outer surface of the second guide portion and the axis of the cleaning port 104 gradually increases, that is, the inclined surface structure of the locking member 108 is transferred to the connecting rod 107, and the second guide portion is exposed in the second opening 112. The release mechanism 202 in the base station 201 passes through the second opening 112 and abuts the second guide portion. As the dust cup assembly continues to descend, the release mechanism 202 pushes the trigger portion 109 toward the locking member 108, thereby pushing the locking member 108 to rotate to open the cleaning port 104.

[0053] 1 and 3 , it can be understood that the switch mechanism 103 further includes a push button 116, which is provided with a first magnetic member 117, and the cup cover 102 is provided with a second magnetic member 118. The second magnetic member 118 engages with the first magnetic member 117 to maintain the cup cover 102 in the first position. Since the locking member 108 is provided with a first hook 301, and the cup cover 102 is provided with a second hook 302, the second hook 302 engages with the first hook 301, and the locking member 108 moves by rotation, and the cup cover 102 also opens the cleaning port 104 by rotation, when the locking member 108 and the cup cover 102 rotate simultaneously, the second hook 302 is difficult to separate from the first hook 301. By adding the push button 116, the push button 116 is connected to the cup cover 102 by magnetic attraction, so that when the locking member 108 rotates, the cup cover 102 can remain in the first position under the action of the magnetic force and does not rotate, thereby facilitating the first hook 301 to separate from the second hook 302, and then prompting the second magnetic member 118 to separate from the first magnetic member 117, or allowing the magnetism of the first magnetic member 117 to disappear or weaken, so that the cup cover 102 can be rotated to the second position to open the cleaning port 104.

[0054] Specifically, the push button 116 includes a force-bearing portion 119, the pushing portion 110 can be slidably connected to the push button 116, and the trigger portion 109 pushes the push button 116 to move by resisting the force-bearing portion 119. The first magnetic member 117 is installed at the bottom of the push button 116, and the force-bearing portion 119 is located above the first magnetic member 117. The push button 116 can be provided with an escape hole or a gap to allow the trigger portion 109 to pass through. After the push button 116 moves, the first magnetic member 117 is disengaged from the second magnetic member 118, thereby allowing the cup cover 102 to rotate and open. When the first hook portion 301 is engaged with the second hook portion 302, a distance is maintained between the trigger portion 109 and the force-bearing portion 119. In other words, after the connecting rod 107 starts to move under the drive of external force, it pushes the locking member 108 to rotate, thereby causing the first hook 301 to rotate and disengage from the second hook 302. During this process, the second magnetic member 118 and the first magnetic member 117 remain in an attracted state, allowing the cup cover 102 to remain stationary relative to the cup body 101. After the first hook 301 is separated from the second hook 302, the connecting rod 107 continues to move a certain distance, causing the trigger part 109 to begin to contact the force-bearing part 119, and the push button 116 begins to move with the connecting rod 107, causing the first magnetic member 117 to move in the direction of disengaging from the second magnetic member 118. After the cup cover 102 loses the magnetic attraction between the second magnetic member 118 and the first magnetic member 117, it begins to rotate to open the cleaning port 104. Through the movement of the connecting rod 107, the two different forces acting on the cup cover 102 can be controlled to be released in sequence, making the structure compact, occupying little space, and effectively improving the opening efficiency of the two hooks.

[0055] It is understood that in some embodiments, the first magnetic member 117 may be a magnet, and the second magnetic member 118 may be an iron sheet. In other embodiments, the first magnetic member 117 may be an electromagnet, with the push button 116 connected to the electromagnet's switch, and the second magnetic member 118 may be an iron sheet, which is energized and magnetically connected to the iron sheet. When the connecting rod 107 moves, causing the first hook 301 to disengage from the second hook 302, the connecting rod 107 continues to move a certain distance, pushing the push button 116, triggering the electromagnet's switch, deactivating the electromagnet, and thus eliminating the magnetic force between the electromagnet and the iron sheet.

[0056] 1 and 3 , it can be understood that a first return member 120 is provided between the push button 116 and the cup body 101. One end of the first return member 120 is connected to the end of the push button away from the connecting rod 107, and the other end is connected to the cup body 101. When the connecting rod 107 pushes the push button and the external force acting on the connecting rod 107 is removed, the push button 116 returns to its original position under the action of the first return member 120. The push button 116 is provided with an anti-slip protrusion 307, and the cup body 101 is provided with a limiting protrusion 306. When the push button 116 is moved toward the second opening 112 by the force of the first reset member 120, the limiting protrusion 306 abuts against the anti-slip protrusion 307, thereby limiting the push button 116, and can control the movement distance of the push button 116 toward the second opening 112, and ensure that when the first hook 301 is engaged with the second hook 302, there is a distance between the trigger part 109 and the force-bearing part 119, thereby accurately controlling the two different forces acting on the cup cover 102 to be released in a determined time sequence, so that the opening action of the cup cover 102 is continuous and smooth.

[0057] It is understandable that the first restoring member 120 may be an elastic structure such as a spring or foam.

[0058] It should be noted that in the above embodiment, the push knob and the connecting rod 107 are arranged in a linked manner to achieve movement at a predetermined interval. In other embodiments, the push knob and the connecting rod 107 can also be arranged independently. That is, the connecting rod 107 can be pushed first to cause the first hook 301 to disengage from the second hook 302, and then the push knob can be pushed from another position to cause the second magnetic member 118 to separate from the first magnetic member 117.

[0059] It should be noted that, in some other embodiments, the locking member 108 can also be locked or unlocked with the cup cover 102 by translational movement. For example, the locking member 108 moves in a direction parallel to the axial direction of the cleaning port 104, the locking member 108 is provided with a third magnetic member, and the cup cover 102 is provided with a fourth magnetic member. The fourth magnetic member and the third magnetic member are attracted to each other to keep the cup cover 102 in the first position. The connecting rod 107 is capable of disengaging the third magnetic member from the fourth magnetic member through various forms of movement. For example, a protrusion is provided on the locking member 108, the pushing portion 110 moves in a direction parallel to the axial direction of the cleaning port 104, and the trigger portion 109 abuts the protrusion, thereby directly pushing the locking member 108 to move in a direction parallel to the axial direction of the cleaning port 104. When the locking member 108 moves in a direction away from the cup cover 102, the fourth magnetic member is disengaged from the third magnetic member. When the locking member 108 moves in a direction close to the cup cover 102, the fourth magnetic member is attracted to the third magnetic member. For another example, a third guide portion is provided on the locking member 108. As the distance between the outer surface of the third guide portion and the axis of the cleaning port 104 gradually increases in a direction away from the cup lid 102, the pushing portion 110 moves in a direction perpendicular to the axial direction of the cleaning port 104. The trigger portion 109 abuts the third guide portion, thereby pushing the locking member 108 to move in a direction parallel to the axial direction of the cleaning port 104. However, due to temperature, dirt on the surfaces of the fourth and third magnetic members, and other factors, the magnetic force may weaken, and the cup lid 102 may not close. Therefore, the locking member 108 is provided with a first hook portion 301, and the cup lid 102 is provided with a second hook portion 302. The second hook portion 302 is engaged with the first hook portion 301, which has a higher reliability.

[0060] 1 and 3 , it can be understood that the cup cover 102 includes a cover portion 121 and a connecting portion 122. The portion of the cup cover 102 used to close the cleaning port 104 is defined as the cover portion 121, and the portion of the cup cover 102 located outside the area corresponding to the cleaning port 104 and used to connect to the cup body 101 is defined as the connecting portion 122. The connecting portion 122 is located at the edge of the cover portion 121, one end of the connecting portion 122 is connected to the cover portion 121, and the other end is rotatably connected to the peripheral wall of the cup body 101 through the rotating shaft 123, that is, the connecting portion 122 uses the rotating shaft 123 as the rotation center, and the rotation center of the connecting portion 122 is located on the peripheral side of the cup body 101, outside the area corresponding to the cleaning port 104.

[0061] 1 and 3 , it can be understood that the dust cup assembly further includes a telescopic structure 124, which has an extended state and a retracted state, and the cup cover 102 and the telescopic structure 124 are combined into a cover assembly. The connecting portion 122 is provided with an active cavity 303, and the telescopic structure 124 is provided in the active cavity 303. When the telescopic structure 124 is in the extended state, the telescopic structure 124 protrudes outside the active cavity 303. When the telescopic structure 124 is in the retracted state, the telescopic structure 124 can be completely retracted into the active cavity 303, or a small part of the structure can be located outside the active cavity 303.

[0062] 2 and 12 , it can be understood that, in order to improve the convenience of using a vacuum cleaner, a base station 201 is typically provided for use with the vacuum cleaner, and the base station 201 is used to clean dust from the vacuum cleaner and to charge the vacuum cleaner. The base station 201 includes a base 203, within which a dust collection chamber 204 is formed. After the vacuum cleaner is placed on the base station 201, part of the dust cup assembly is inserted into the dust collection chamber 204, and the outer peripheral wall of the cup body 101 is in contact with the inner wall of the dust collection chamber 204.

[0063] As shown in FIG2 , it can be understood that a release mechanism 202 is provided in the base station 201. The release mechanism 202 is used to push the connecting rod 107 to move, thereby unlocking the locking member 108 from the cup cover 102. In one embodiment, the release mechanism 202 includes a push rod 205. The push rod 205 is vertically arranged. When the dust cup assembly is installed in the dust collection chamber 204, the push rod 205 passes through the second opening 112 and abuts against the connecting rod 107, thereby prompting the connecting rod 107 to push the locking member 108 to rotate, thereby eliminating the interaction force between the locking member 108 and the cup cover 102. The release mechanism 202 also includes a return spring 206. The return spring 206 is connected to the bottom end of the push rod 205. The return spring 206 can make the push rod 205 protrude from the base 203, making it easier to align with the second opening 112. In addition, during the process of the dust cup assembly being installed in the dust collection chamber 204, the return spring 206 can also act as a buffer, reducing the impact force and noise generated by the dust cup assembly.

[0064] It should be noted that in some other embodiments, the release mechanism 202 can also be a rib fixedly arranged in the base station 201, or a power mechanism with a lifting function, and the switch mechanism 103 can omit the connecting rod 107, and only the rib or power mechanism can push the locking member 108 to move.

[0065] Referring to Figures 1 and 3, it can be understood that the outer wall of the cup body 101 is provided with a second mounting portion 125, and the position of the cup body 101 close to the cleaning port 104 is partially concave inward and partially protrudes outward, thereby forming the second mounting portion 125, and the connecting portion 122 is rotatably connected to the second mounting portion 125.

[0066] It should be noted that the second mounting portion 125 can be located inside the cup body 101 or outside the cup body 101 .

[0067] As shown in Figure 3, it can be understood that the second mounting portion 125 is provided with a concave cavity 305, and the connecting portion 122 is connected to the side wall of the concave cavity 305. When the cup cover 102 is in the first position, the connecting portion 122 is completely accommodated in the concave cavity 305, preventing the connecting portion 122 from interfering with the side wall of the dust collecting chamber 204, thereby facilitating the removal and installation of the dust cup assembly into the base station 201.

[0068] 2 and 12 , it can be understood that the inner wall of the dust collecting chamber 204 is provided with a recess 207 , which is configured to accommodate the portion of the cover assembly protruding from the outer peripheral wall of the cup body 101 , that is, the aperture of the dust collecting chamber 204 at the recess 207 is larger than the aperture at the entrance 208 .

[0069] 12 , it can be understood that when the cup cover 102 is in the second position, the telescopic structure 124 protrudes from the outermost side of the second mounting portion 125. Alternatively, the surface of the outermost peripheral wall of the cup body 101 where the second mounting portion 125 is located is defined as surface H, and the telescopic structure 124 protrudes from surface H in a direction away from the centerline of the cleaning port 104. When the dust cup assembly is removed, the cover assembly located at the recess 207 moves toward the entrance 208 of the dust collection chamber 204. During this process, the telescopic structure 124 contacts the sidewall of the dust collection chamber 204, causing the telescopic structure 124 to transition from an extended state to a retracted state. Simultaneously, the connecting portion 122 also opens outward, moving closer to the sidewall of the cup body 101. During the retraction process, the telescopic structure 124 transmits a force to the cup cover 102, which drives the connecting portion 122 to rotate about the rotation center, thereby driving the cup cover 102 from the second position to the first position.

[0070] It can be understood that in addition to providing assistance in the process of removing the dust cup assembly from the base station 201, the telescopic structure 124 can also be used to shrink toward the active cavity 303 during the process of removing the dust cup assembly and during the process of installing the dust cup assembly, thereby reducing the resistance encountered by the dust cup assembly during the removal and installation process.

[0071] 1 and 3 , it can be understood that the telescopic structure 124 includes an elastic member 127 and a movable block 128. The two ends of the elastic member 127 are respectively connected to the movable block 128 and the bottom wall of the movable chamber 303, and the movable block 128 is movably arranged in the movable chamber 303. When the telescopic structure 124 is in the extended state, the elastic member 127 provides an elastic force, which enables part of the movable block 128 to extend out of the movable chamber 303. When the movable block 128 contacts the side wall of the dust collecting chamber 204, the movable block 128 contracts into the movable chamber 303, and the elastic member 127 is also squeezed and compressed. The elastic force generated by the compression of the elastic member 127 is transmitted to the cup cover 102, and the cup cover 102 has a tendency to rotate around the rotation center.

[0072] 1 and 3 , it can be understood that the movable block 128 is provided with a limiting buckle 129, and the side wall of the movable cavity 303 is provided with a positioning protrusion 304. Under the action of the elastic member 127, the movable block 128 moves toward the opening of the movable cavity 303, and the limiting buckle 129 abuts against the positioning protrusion 304 to prevent the movable block 128 from escaping from the movable cavity 303. It can also limit the height of the movable block 128 protruding from the active cavity 303, thereby reducing the resistance encountered by the dust cup assembly during the process of removing and loading the base station 201, and facilitating the end of the movable block 128 to contact the side wall of the dust collecting cavity 204 and shrink into the active cavity 303 in time.

[0073] 1 and 3 , it can be understood that the portion of the movable block 128 protruding from the movable cavity 303 is constructed as a boss 126, and the cross-sectional area of ​​the boss 126 gradually decreases in the direction away from the connecting portion 122. In other words, the boss 126 as a whole can be a step or a cone, with the large end of the boss 126 close to the elastic member 127, and the small end being used to contact the side wall of the dust collecting cavity 204, thereby reducing frictional resistance. In addition, the boss 126 also has an inclined surface. When removing the dust cup assembly, the inclined surface can guide the contact point between the boss 126 and the side wall of the dust collecting cavity 204 to transition from the large end of the boss 126 to the small end, making the entire removal process smoother and also helping the cup cover 102 to close better.

[0074] As shown in Figure 3, it can be understood that the end of the movable block 128 away from the cleaning port 104 is rotatably connected to the connecting portion 122. When the end of the movable block 128 contacts the side wall of the dust collecting chamber 204, the movable block 128 realizes the function of contraction by rotating into the movable chamber 303, and the force point generated by the elastic member 127 is farther away from the rotation center of the connecting portion 122, which can generate a larger rotational torque, thereby facilitating the rotation of the cup cover 102 to the first position. In addition, the movable block 128 is generally made of plastic material, and the limit buckle 129 is connected by an elastic arm to form an elastic buckle that cooperates with the positioning protrusion 304. One end of the movable block 128 is rotatably connected to the connecting portion 122, which can reduce the contact between the elastic buckle and the inner wall of the movable chamber 303 and extend the service life of the elastic buckle.

[0075] It is understood that in some other embodiments, the movable block 128 can also translate as a whole along the axial direction of the movable cavity 303 to provide assistance in closing the cup lid 102. In other words, the movable block 128 translates along the expansion and contraction direction of the elastic member 127, and the expansion and contraction direction of the elastic member 127 is perpendicular to the bottom wall of the connecting portion 122.

[0076] It should be noted that, in some other embodiments, the telescopic structure 124 may also be an integrated structure. For example, the telescopic structure 124 is a rubber piece, and the elasticity of the rubber is used to achieve the contraction and extension of the rubber piece as a whole.

[0077] 2, 9 to 11, it can be understood that the base station 201 further includes a limit rod 209 and a limit switch 210. The limit rod 209 is movably disposed in the recess 207. Under normal conditions, the limit rod 209 is located in the recess 207 and the inner edge of the limit rod 209 is substantially in the same plane as the inner wall of the dust collecting chamber 204 at the entrance 208, so that after the cover assembly enters the recess 207, the limit rod 209 can still limit the telescopic structure 124, so that the telescopic structure 124 provides a force on the cup cover 102, allowing the cup cover 102 to remain in the first position. The limit switch 210 is used to promote the movement of the limit rod 209, and the limit rod 209 moves toward the outside of the recess 207, so that the limit rod 209 can be separated from the telescopic structure 124, and the telescopic structure 124 also changes from the retracted state to the extended state. The force of the telescopic structure 124 on the cup cover 102 disappears, and the cup cover 102 can rotate to the second position.

[0078] It is understood that the limit rod 209 cooperates with the telescopic structure 124 to keep the cup cover 102 in the first position, facilitating the first hook 301 to disengage the second hook 302, and then allowing the cup cover 102 to rotate to the second position. In addition, by providing a limit switch 210 to control the limit rod 209, the user can conveniently control the dust cup assembly dust discharge time as needed.

[0079] 9 to 11 , it can be understood that the limit switch 210 moves in an up-and-down direction, and the user can control the limit rod 209 by pressing it, while the limit rod 209 moves in a direction perpendicular to the axis of the dust collection chamber 204. To facilitate the reset of the limit switch 210 and the limit rod 209, a first spring 1101 is provided between the limit switch 210 and the base 203, and a second spring 1102 is provided between the limit rod 209 and the base 203. The limit rod 209 is provided with a fourth guide portion 901, on which the limit switch 210 slides. The fourth guide portion 901 can be an inclined surface. When the limit switch 210 moves downward, the limit rod 209 is forced to move away from the telescopic structure 124. At this time, the limit rod 209 releases the limit on the telescopic structure 124, allowing the cup lid 102 to rotate and open. In the state shown in Figure 9 , the limit switch 210 is located at the upper end of the fourth guide portion 901, and the limit rod 209 can limit the telescopic structure 124. In the state shown in Figure 10 , the limit switch 210 is located at the lower end of the fourth guide portion 901, and the limit rod 209 releases the limit on the telescopic structure 124.

[0080] The following describes the working process of the dust cup assembly of an embodiment of the present application with reference to Figures 2 to 8. The order of Figures 2 to 8 shows the process of installing the dust cup assembly into the base station 201, and the order of Figures 8 to 2 shows the process of removing the dust cup assembly from the base station 201.

[0081] Figures 2 and 3 show the dust cup assembly before it is installed in the base station 201. At this time, the cup cover 102 remains in the first position, the first hook 301 is disengaged from the second hook 302, the trigger portion 109 is located at the lower end of the first guide portion 115, the force-bearing portion 119 is located above the trigger portion 109 with a gap, the second magnetic member 118 is attracted to the first magnetic member 117, and the telescopic structure 124 is in the extended state.

[0082] Figure 4 shows the state when the dust cup assembly is installed in the base station 201 and the push rod 205 just contacts the connecting rod 107. At this time, the telescopic structure 124 is squeezed by the side wall of the entrance 208 of the dust collecting chamber 204, the movable block 128 is located in the movable chamber 303, and the elastic member 127 is compressed.

[0083] Figure 5 shows the state when the locking member 108 is disengaged from the cup cover 102. At this time, the push rod 205 pushes the connecting rod 107 to slide, and the trigger part 109 moves to the upper end of the first guide part 115 and just contacts the force-bearing part 119. During the sliding process of the connecting rod 107, the second magnetic part 118 is attracted to the first magnetic part 117, and the telescopic structure 124 is in a retracted state. The trigger part 109 always moves on the first guide part 115, pushing the locking member 108 to rotate. Before the trigger part 109 contacts the force-bearing part 119, the first hook part 301 begins to disengage from the second hook part 302. After the trigger part 109 contacts the force-bearing part 119, the first hook part 301 completely disengages from the second hook part 302. However, since the cup cover 102 is still subject to the attraction force between the second magnetic member 118 and the first magnetic member 117, as well as the elastic force of the telescopic mechanism, the cup cover 102 is still able to close the cleaning port 104, that is, the cup cover 102 is still in the first position.

[0084] Figure 6 shows the state when the second magnetic member 118 is disengaged from the first magnetic member 117. At this time, the push rod 205 pushes the connecting rod 107 to continue to slide upward, driving the push button 116 to continue to move upward, so that the first magnetic member 117 gradually disengages from the second magnetic member 118. During the sliding process of the connecting rod 107, the trigger part 109 always moves on the first guide part 115, squeezing the locking member 108, so that the locking member 108 rotates a larger angle. When the connecting rod 107 and the push button 116 are close to the top of the first mounting part 106, the first magnetic member 117 is completely disengaged from the second magnetic member 118. During this process, the movable block 128 is squeezed into the movable cavity 303 by the limiting rod 209, the elastic member 127 is compressed, and the elastic force of the elastic member 127 pre-presses the cup cover 102, so that the cup cover 102 is in the first position.

[0085] Figure 7 shows the dust cup assembly installed at the bottom of the base station 201. At this point, the push rod 205 is pressed downward by the connecting rod 107, and eventually the top of the push rod 205 is flush with the upper surface of the base 203. The connecting rod 107 abuts the upper surface of the base 203, and the dust cup assembly is placed in place. During this process, the movable block 128 is squeezed into the movable cavity 303 by the limiting rod 209, and the elastic member 127 is compressed. The elastic force of the elastic member 127 pre-compresses the cup cover 102, causing the cup cover 102 to be in the first position.

[0086] Figure 8 shows the state of the cup lid 102 when it is open. At this time, the limit switch 210 is manually pressed, and the bottom of the limit switch 210 slides on the fourth guide portion 901 of the limit rod 209. The limit rod 209 moves under the force. At this time, the limit rod 209 releases the limit on the telescopic structure 124, and part of the movable block 128 can extend out of the movable cavity 303. The elastic force on the cup lid 102 is weakened to the point that it is insufficient to keep the cup lid 102 in place. The cup lid 102 begins to rotate open, and the garbage in the dust cup assembly is collected by the base station 201.

[0087] After cleaning is complete, the cup lid 102 is in the open state shown in Figure 8. During the removal of the dust cup assembly, the dust cup assembly as a whole moves upward. As shown in Figure 6, the movable block 128 collides with the side wall of the base 203, providing a thrust to the movable block 128, prompting the movable block 128 to move toward the interior of the movable cavity 303, thereby compressing the elastic member 127. The elastic member 127 transmits the force to the cup lid 102, causing the cup lid 102 to rotate upward around the rotation center. At this time, the push button is reset under the action of the first reset member 120, and the force-bearing portion 119 pushes the trigger portion 109 downward. As the connecting rod 107 moves downward, the opening angle of the locking member 108 decreases under the action of the second reset member 114, that is, the first hook 301 rotates toward the second hook 302. When the cup lid 102 moves from the second position to near the first position, the second magnetic member 118 and the first magnetic member 117 generate an attractive force, helping the cup lid 102 to close. At this time, the first hook 301 is completely separated from the second hook 302. As the dust cup assembly is further removed, the second return member 114 fully resets the latch 108, and the first hook 301 engages the second hook 302, helping to better maintain the cup cover 102 in the first position. The connecting rod 107 is also fully reset under the push of the first guide 115, eliminating the need for a separate elastic structure such as a spring or foam to reset the connecting rod 107. When the dust cup assembly is fully removed, it appears as shown in Figure 2.

[0088] According to the dust cup assembly of the embodiment of the present application, the connecting rod directly acts on the locking member to realize the function of opening the cup lid. Specifically, the user manually opens the dust cup lid by pushing the pushing part on the side of the cup body. When the dust cup assembly is placed in the base station, the base station can push the trigger part axially from the cup body to open the dust cup lid. The overall structure is compact and occupies little space.

[0089] The vacuum cleaner of the embodiment of the present application includes the dust cup assembly of all the above-mentioned embodiments. Since the vacuum cleaner has all the technical features of the dust cup assembly of all the above-mentioned embodiments, it also has all the beneficial effects thereof, which will not be described in detail here.

Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
