Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a vacuum cleaner device and a vacuum cleaner system. Background Art

[0002] Vacuum cleaner equipment, such as vacuum cleaners, floor scrubbers, sweepers, etc., can be connected to the dust collection station after cleaning to suck out the dirt in the dust collection chamber of the vacuum cleaner equipment. The dust collection process of the vacuum cleaner equipment is completed by the dust collection station, and the user does not need to manually empty the dust. In this way, the user does not need to empty the dust after each cleaning. The user can empty the dust once a month or even longer.

[0003] Specifically, the vacuum cleaner device is provided with a dust cup body for storing dirt, and the dust cup body is formed with a first dust storage chamber and a second dust storage chamber separated by a filtering mechanism, wherein the first dust storage chamber is generally used to store dirt with larger particle sizes, and the second dust storage chamber is generally used to store dirt with smaller particle sizes. In the prior art, the dust outlets of the first dust storage chamber and the second dust storage chamber are usually blocked by the same cover body. After the vacuum cleaner device is docked with the dust collection station, the cover body is opened, so that the first dust storage chamber and the second dust storage chamber are connected to the dust collection station, so that the dust in the vacuum cleaner device can be collected by the dust collection station. However, due to the movable arrangement of the cover body, the vacuum cleaner device is prone to displacement or deformation after long-term use, resulting in a loose seal between the first dust storage chamber and the second dust storage chamber, and even crossflow when the vacuum cleaner device is performing normal cleaning work, which has an adverse effect on the cleaning effect and the service life of the vacuum cleaner device.

[0051] The realization of the purpose, functional features and excellent effects of the utility model will be further explained below with reference to specific embodiments and drawings. DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] It should be noted that if directional indications are involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0054] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0055] See also Figures 1 to 10 The present invention provides a vacuum cleaner device and a vacuum cleaner system 1000 including the vacuum cleaner device and a dust collection station. Figure 1 and Figure 2 As shown, the dust collection station 200 can be connected to the vacuum cleaner device. Specifically, before the vacuum cleaner device is connected to the dust collection station 200, it can be moved closer to the dust collection station 200 along the connection direction, and preferably plugged into the dust collection station 200 along the connection direction to achieve connection with the dust collection station 200. When or after the dust collection station 200 and the vacuum cleaner device are connected, a negative pressure can be generated in the dust collection station 200 to suck dirt from the vacuum cleaner device into the dust collection station 200, thereby achieving self-cleaning of the vacuum cleaner device.

[0056] Specifically, a dust collecting chamber is formed in the dust collecting station 200. When the dust collecting station 200 and the vacuum cleaner device are connected or connected, the dust collecting chamber can be connected to the dust cup assembly of the vacuum cleaner device and generate negative pressure, thereby sucking the dirt in the vacuum cleaner device into the dust collecting chamber to achieve self-cleaning of the vacuum cleaner device. It should be noted that in one embodiment, the negative pressure formed in the dust collecting chamber is provided by the dust collecting station 200 itself. However, in this embodiment, the dust collecting station 200 needs to be provided with a motor and a power device such as a dust exhaust channel or components connected to the motor, which makes the internal structure of the dust collecting station 200 complicated and increases the production cost of the dust collecting station 200.

[0057] In another embodiment, the negative pressure generated within the dust collection chamber is provided by a power device on the vacuum cleaner device, thereby sucking dirt from the vacuum cleaner device into the dust collection station 200, thereby achieving self-cleaning of the vacuum cleaner device. In this way, the vacuum cleaner device's own power device, such as a motor, is used to provide negative pressure for the dust collection station 200. This eliminates the need for a power device on the dust collection station 200 itself, resulting in a simpler structure and lower costs.

[0058] The specific form of the vacuum cleaner device is not limited, and in actual application, the use orientation of the vacuum cleaner device may be different. However, for ease of understanding, in the following embodiments, Figure 1 The handheld vacuum cleaner device shown is used as an example for explanation. At this time, the vacuum cleaner device is in a docking state with the dust collection station 200, and has a roughly vertical up and down direction and a horizontal direction, wherein the up and down direction is roughly parallel to the direction of extension of gravity, and the docking direction is preferably parallel to the up and down direction.

[0059] Specifically, the vacuum cleaner device includes a device body, a dust cup assembly 100 and a suction device. The device body is mainly used to install and support various components of the vacuum cleaner device, and the dust cup body and the suction device are both installed on the device body.

[0060] Specifically, see Figures 3 to 7The dust cup assembly 100 includes a dust cup body 10, a filter mechanism 30 and a blocking mechanism 40. Specifically, the dust cup body 10 is provided with an air inlet 20 and an air outlet, and an air duct connecting the air inlet 20 and the air outlet is formed inside the dust cup body 10. The filter mechanism 30 is installed in the air duct. When the vacuum cleaner device performs normal cleaning work, the suction device drives the air flow from the air inlet 20 into the air duct, and flows through the filter mechanism 30 and then flows out from the air outlet. The dirt formed by filtering by the filter mechanism 30 is stored in the dust cup body 10. Generally speaking, the dust cup body 10 is arranged in a cylindrical shape, and its air inlet 20 is opened on the peripheral side of the dust cup body 10, and the air outlet is arranged on the end side of the dust cup body 10. Preferably, the dust cup body 10 has a first end 11 and a second end 12 that are arranged opposite to each other, the first end 11 is located above the second end 12, and the air outlet is arranged at the first end 11. It should be noted that the description of upstream and downstream in this embodiment is only based on the direction in which the suction device drives the airflow when the vacuum cleaner device performs normal cleaning work.

[0061] Further, please continue to refer to Figure 8 The filter mechanism 30 includes a first filter device 31 and a second filter device 32 installed within the dust cup 10. The first filter device 31 is positioned upstream of the second filter device 32. A first dust storage chamber 21 is formed between the air inlet side of the first filter device 31 and the air inlet 20. Specifically, the first dust storage chamber 21 is primarily used to store dirt filtered by the first filter device 31. A second dust storage chamber 22 is formed between the air outlet side of the first filter device 31 and the air outlet side of the second filter device 32. Specifically, the second dust storage chamber 22 is primarily used to store dirt filtered by the second filter device 32. It will be appreciated that because the first and second filter devices 31, 32 are positioned sequentially along the airflow direction, the dirt stored in the first dust storage chamber 21 is generally larger than the dirt stored in the second dust storage chamber 22. The first dust storage chamber 21 has a first dust outlet 23 that communicates with the outside of the dust cup 10, and the second dust storage chamber 22 has a second dust outlet 24 that communicates with the outside of the dust cup 10. After the vacuum cleaner device is docked with the dust collecting station 200 and enters the self-cleaning state, the first dust outlet 23 and the second dust outlet 24 are both opened, so that the first dust storage chamber 21 and the second dust storage chamber 22 are connected to the dust collecting cavity, so that the dirt in the dust cup assembly 100 can be sucked into the dust collecting station 200.

[0062] In this embodiment, the suction device refers to any device capable of driving a directional flow of gas, and may be composed of a single component (e.g., a fan) or a combination of at least two components (e.g., a fan and an air guide structure). The suction device may include, for example, a fan, which may be, but is not limited to, an axial flow fan, a crossflow fan, a centrifugal fan, or the like.

[0063] The specific models of the first filter device 31 and the second filter device 32 can be selected according to the filtering requirements. In an optional embodiment, please refer to Figure 8 The first filter device 31 is a porous filter, the second filter device 32 is a multi-cone filter, and the filter mechanism 30 further includes a HEPA filter 33 disposed at the first end 11 of the dust cup body 10 and connected to the air outlet side of the second filter device 32. The suction device is generally disposed on the air outlet side of the HEPA filter 33. In this way, when the vacuum cleaner device performs normal cleaning work, the first blocking member 411 and the second blocking member 421 are both in a closed state, and the suction device works, driving the airflow from the air inlet 20 into the first dust storage chamber 21, flowing through the first filter device 31, leaving larger particles of dirt in the first dust storage chamber 21, and then flowing into the second dust storage chamber 22. The second filter device 32 in the second dust storage chamber 22 filters out smaller particles of dirt, and leaves the dirt in the second dust storage chamber 22 before flowing to the air outlet, filtering through the HEPA filter 33, and then flowing through the suction device. In this way, the airflow containing dirt sucked by the vacuum cleaner equipment is filtered more than 30 times by the filtering mechanism and then flows to the suction device, ensuring that the airflow flowing through the suction device is clean, avoiding adverse effects on the suction device and the air environment, and extending the service life of the vacuum cleaner equipment.

[0064] For further information, please continue to read Figures 3 to 7 The blocking mechanism 40 includes a first blocking structure 41 and a second blocking structure 42 mounted on the dust cup body 10. The first blocking structure 41 includes a first blocking member 411 for opening or closing the first dust outlet 23, and the second blocking structure 42 includes a second blocking member 421 for opening or closing the second dust outlet 24. The specific structure and movement of the first blocking member 411 and the second blocking member 421 are not limited, as long as they can effectively block the first dust storage chamber 21 and the second dust storage chamber 22 respectively when closed, and can open the first dust outlet 23 and the second dust outlet 24 when opened.

[0065] In this embodiment, since the first dust storage chamber 21 and the second dust storage chamber 22 are blocked by the first blocking member 411 and the second blocking member 421 respectively, the movement, deformation and blocking position of the first blocking member 411 and the second blocking member 421 basically do not affect each other. This improves the situation where the first dust storage chamber 21 and the second dust storage chamber 22 are blocked by the same blocking member and thus have a loose seal. Specifically, this prevents the same blocking member from deforming or shifting after the vacuum cleaner device is used for a long time, causing the first dust storage chamber 21 and the second dust storage chamber 22 to be connected or even cross-flowing under normal cleaning conditions. In this way, the cleaning effect of the vacuum cleaner device after long-term use can be improved and its service life can be extended.

[0066] In a preferred embodiment, a first air duct and a second air duct are formed in the main body of the device. The first air duct connects the suction device and the dust cup assembly 100, and the second air duct is suitable for connecting the suction device and the dust collecting station 200. In this way, the suction device can be controlled to selectively connect to the dust cup assembly 100 or the dust collecting station 200 by controlling the conduction state of the first air duct and the second air duct. Specifically, when the suction device is connected to the dust cup assembly 100, negative pressure can be generated in the dust cup assembly 100, and the dirt can be sucked into the dust cup assembly 100 when the vacuum cleaner device is performing cleaning work. When the suction device is connected to the dust collecting station 200, negative pressure can be generated in the dust collecting cavity thereof, and then when the vacuum cleaner device is docked on the dust collecting station 200, the dirt in the dust cup assembly 100 is sucked into the dust collecting cavity to achieve self-cleaning of the vacuum cleaner device. In this embodiment, the suction device can provide negative pressure for the dust collecting station 200 so that the dirt in the first dust storage chamber 21 and the second dust storage chamber 22 is sucked into the dust collecting station 200. There is no need to set a power device for self-cleaning the dust cup assembly 100 on the dust collecting station 200. The structure of the dust collecting station 200 can be simpler and the cost is lower.

[0067] Preferably, the vacuum cleaner device further includes an air duct switching structure, through which the air duct connection state inside the vacuum cleaner device can be switched, so that the suction device selects to be connected to at least one of the dust cup assembly 100 and the dust collection station 200. The air duct switching structure can be movably set to connect or block the first air duct and the second air duct. In an optional embodiment, when the vacuum cleaner device enters the normal cleaning working mode, the air duct switching structure can be controlled to connect the first air duct and block the second air duct. At this time, the suction device is connected to the dust cup assembly 100, and the dirt is sucked from the outside of the vacuum cleaner device into the dust cup body 10, specifically sucked into the first dust storage chamber 21 and the second dust storage chamber 22 for storage. When the vacuum cleaner device is docked with the dust collecting station 200 and enters the self-cleaning working mode, the air duct switching structure can be controlled to connect the second air duct and block the first air duct. At this time, the suction device can be connected to the dust collecting chamber of the dust collecting station 200, so that a negative pressure is formed in the dust collecting chamber, and then the dirt retained in the dust cup assembly 100 is sucked into the dust collecting chamber, thereby realizing self-cleaning of the vacuum cleaner device.

[0068] It can be understood that if both the first air duct and the second air duct are in a conducting state, the airflow generated by the suction device will be split, and the suction force entering each air duct will be weakened; if both the first air duct and the second air duct are in a blocked state, there will be no continuous airflow entering the air inlet side of the suction device, and a vacuum will be formed. The pressure on the air inlet side of the suction device is too low, which will cause the air inlet side air duct to be squeezed and deformed, or the suction device will overheat and be damaged. Therefore, preferably, the air duct switching structure includes a first shielding portion and a second shielding portion that are movably arranged in the vacuum cleaner device, the first shielding portion is used to block and conduct the first air duct, and the second shielding portion is used to block and conduct the second air duct. The first shielding portion and the second shielding portion are movable so that when one of the first air duct and the second air duct is in a conducting state, the other is in a blocked state. In this embodiment, by providing the first shielding portion and the second shielding portion, the airflow generated by the suction device can only flow along one path, which can avoid the phenomenon of both paths being connected or both paths being blocked, and can better protect the vacuum cleaner device.

[0069] In another embodiment, only one of the first and second shielding portions may be provided, and the movement of the single shielding portion can be used to open and close the first and second air ducts, thereby switching the conductive state of the first and second air ducts. In this embodiment, by providing separate first and second shielding portions to block and open the first and second air ducts, respectively, the movable travel of the first and second shielding portions can be shortened, occupying less internal space, and thus achieving a more compact structure.

[0070] The first and second shielding parts can be independently configured, meaning their movement patterns can differ. For example, the second shielding part can move to open the second airway after or before the first shielding part blocks the first airway; or the second shielding part can move to block the second airway after or while the first shielding part opens the first airway. This allows for greater flexibility in the movement of the first and second shielding parts without interfering with each other.

[0071] Preferably, the first and second shielding parts are arranged in a linked manner, that is, the first and second shielding parts move synchronously. In this way, while the first shielding part blocks the first air duct, the second shielding part opens the second air duct; while the second shielding part blocks the second air duct, the first shielding part opens the first air duct. This improves the working performance of the vacuum cleaner.

[0072] Based on the above embodiment, there are many ways to implement the first blocking structure 41 and the second blocking structure 42. In a preferred embodiment, the closing and / or locking actions of the first blocking structure 41 and the second blocking structure 42 are linked. Figures 1 to 7 ,as well as Figure 10The first blocking structure 41 is provided with a limited portion 412, see Figure 4 When the first blocking structure 41 closes the first dust outlet 23, the limiting portion 412 acts on the second blocking structure 42, so that the second blocking member 421 is restricted to the closed position blocking the second dust outlet 24. When the first blocking structure 41 opens the first dust outlet 23, the limiting portion 412 moves away from the second blocking structure 42 to release the restriction on the second blocking member 421. In this way, when the first blocking structure 41 switches to the closed state, it uses the limiting portion 412 to drive the second blocking member 421 to close. When the first blocking structure 41 is locked and maintained in the closed state, the movement of the second blocking member 421 can be restricted, so that it also remains in the closed position. In this way, the closing drive structure and the locking structure can be provided only in the first blocking structure 41, and the second blocking structure 42 can use the closing drive structure and the locking structure of the first blocking structure 41 to achieve the closing and locking of the second blocking member 421. The overall structure of the blocking mechanism 40 is simpler and more reliable.

[0073] When the first blocking structure 41 switches to the open state, there can be multiple ways to drive the second blocking member 421 to open. In the optional first embodiment, when the limiting portion 412 releases the limit on the second blocking member 421, the second blocking member 421 is displaced under the action of gravity to move to the open position to open the second dust outlet 24. In this embodiment, the second blocking member 421 can be movably arranged in the up and down directions, for example, it can slide downward to open the second dust outlet 24 or rotate downward to open the second dust outlet 24. In this way, when the first blocking member 411 opens the first dust outlet 23, the second blocking member 421 can be displaced under the action of gravity to automatically move to the open position to open the second dust outlet 24. In this embodiment, there is no need to set up an additional driving structure to drive the second blocking member 421 to open the second dust outlet 24. The overall structure of the second blocking structure 42 is simple, easy to implement, and has low production cost.

[0074] In the second embodiment, see Figure 6 The second blocking structure 42 further includes an elastic driving member in transmission connection with the second blocking member 421. When the second blocking member 421 is in the closed position, the elastic driving member elastically deforms. When the limiting portion 412 releases the limit on the second blocking member 421, the elastic driving member elastically resets, thereby driving the second blocking member 421 to the open position, thereby opening the second dust outlet 24. In this embodiment, the elastic reset force of the elastic driving member is utilized to actively drive the second blocking member 421 to open the second dust outlet 24. This prevents the second blocking member 421 from becoming stuck in the absence of external force, preventing it from opening smoothly to discharge waste.

[0075] In the third embodiment, the second blocking structure 42 further includes an elastic retaining member that is transmission-connected to the second blocking member 421. When the limiting portion 412 releases the limiting function on the second blocking member 421, as shown in FIG. Figure 7 As shown, the elastic retaining member provides a holding force to keep the second blocking member 421 in the closed position, so that in the absence of external force, the second blocking member 421 is kept in the closed position. After the vacuum cleaner device is docked with the dust collection station 200, when negative pressure is generated in the dust collection station 200, the second blocking member 421 overcomes the holding force under the action of the negative pressure and moves to the open position to open the second dust outlet 24. At this time, Figure 6 As shown, the first blocking member 411 and the second blocking member 421 are both in the open position, and the first dust outlet 23 and the second dust outlet 24 are opened at the same time.

[0076] It should be noted that, in the third embodiment, the first blocking member 411 can be opened before the second blocking member 421. For example, when the user wants to manually discharge the dirt in the dust cup body 10, the user can choose to open only the first blocking member 411 while the second blocking member 421 remains closed. Only the dirt in the first dust storage chamber 21 is discharged, while the dirt in the second dust storage chamber 22 remains in the dust cup body 10, thereby improving the situation of fine dust scattering and enhancing the user experience.

[0077] In the third embodiment, the first blocking member 411 and the second blocking member 421 can also be opened sequentially after docking with the dust collecting station 200. Specifically, the first blocking member 411 can be opened automatically after the vacuum cleaner device is docked with the dust collecting station 200, or can be controlled to open under a control command after docking with the dust collecting station 200. At this time, negative pressure has not yet been generated in the dust collecting chamber, and most of the dirt in the first dust storage chamber 21 can automatically fall into the dust collecting chamber under the action of gravity. When negative pressure is generated in the dust collecting station 200, the second blocking member 421 opens the second dust outlet 24 under the action of the negative pressure, and the dirt remaining in the first dust storage chamber 21 and the second dust storage chamber 22 is sucked into the dust collecting chamber. This can reduce the workload of the power device that provides negative pressure to the dust collecting station 200, and at the same time improve the situation where a large amount of dirt is simultaneously sucked into the exhaust port connected to the dust collecting chamber, resulting in blockage of the exhaust port.

[0078] Based on the above examples, please refer to Figure 5The first dust storage chamber 21 is arranged around the outer periphery of the second dust storage chamber 22, and the first dust outlet 23 and the second dust outlet 24 are both located at the second end 12. The first dust outlet 23 is arranged around the outer periphery of the second dust outlet 24. In this way, the airflow sucked into the dust cup body 10 flows along a spiral path through the first dust storage chamber 21 and then flows into the second dust storage chamber 22, thereby improving the filtering effect. The large area of ​​the first dust outlet 23 and the small area of ​​the second dust outlet 23 are conducive to the quick discharge of large-sized dirt from the first dust outlet 23, thereby improving the discharge efficiency. Small-sized dirt is concentrated and discharged from the second dust outlet 24, thereby reducing the scattering of fine dust.

[0079] Further, see Figure 6 、 Figure 7 and Figure 10 , the first blocking member 411 is movably covered at the first dust outlet 23, and a through hole 413 is opened corresponding to the second dust outlet 24. When the first blocking member 411 closes the first dust outlet 23, the inner side of the through hole 413 is blocked by the second blocking member 421. Preferably, the limiting portion 412 is arranged on the inner side of the first blocking member 411 and is located in the middle of the first blocking member 411, and the through hole 413 passes through the limiting portion 412 along the axial direction. Therefore, the limiting portion 412 and the through hole 413 are both arranged corresponding to the second dust outlet 24. The provision of the through hole 413 in this embodiment is conducive to the airflow entering between the first blocking member 411 and the second blocking member 421, avoiding the formation of a vacuum between the first blocking member 411 and the second blocking member 421. Since the negative pressure is bonded together, the opening and closing actions of the two can only be performed simultaneously, and not independently of each other.

[0080] Optionally, the first filter device 31 is disposed around the outer periphery of the second filter device 32. The filter mechanism 30 further includes a dust hopper 34 having an inlet end 341 relatively close to the first end 11 and an outlet end 342 relatively close to the second end 12. A dust collection channel 340 is formed in the dust hopper 34, extending from the inlet end 341 to the outlet end 342. In this embodiment, the inlet end 341 is larger than the outlet end 342. The dust collection channel 340 is tapered from the inlet end 341 to the outlet end 342 to collect waste discharged from the second filter device. The inlet end 341 connects to the end side of the first filter device 31 and the second filter device 32 facing the second end 12 to collect waste in the second dust storage chamber 22. The outlet end 342 defines a second dust outlet 24 connected to the dust collection channel 340, so that after the vacuum cleaner device is docked with the dust collection station 200, waste is discharged into the dust collection chamber through the second dust outlet 24. In this embodiment, the first filter device 31 has a larger air inlet area, thereby improving the air flow efficiency. The end side of the second filter device 32 is connected to the inlet end 341 of the dust hopper 34 to remove the filtered dirt as quickly as possible to improve the filtering efficiency. The fine dirt is collected by the dust hopper 34 and then discharged, improving the situation of fine dirt being scattered.

[0081] The specific forms of the first blocking structure 41 and the second blocking structure 42 can be designed as needed. Figures 3 to 7 The first blocking member 411 can be rotatably mounted on the dust cup body 10 and has a rotating end and a free end that are arranged opposite to each other. The first blocking structure 41 also includes a pivot member 414 and a locking member 415 arranged on the dust cup body 10. The rotating end is rotatably connected to the dust cup body 10 through the pivot member 414, and the free end is rotatably arranged around the rotating end. When the first blocking member 411 is in the closed position, the free end can be locked to the dust cup body 10 by the locking member 415 to maintain the closed position. When the vacuum cleaner device is docked with the dust collection station 200, the locking member 415 can be triggered by the dust collection station 200 to release the lock on the first blocking member 411, allowing it to rotate to the open position. The pivot member 414 can include an elastic component that can drive the first blocking member 411 to open, such as a torsion spring, so that when the first locking member 415 is unlocked, it can be automatically driven to the open position.

[0082] Optionally, see Figures 6 to 10 The second blocking member 421 is axially movably mounted on the dust collection passage 340. When the second blocking member 421 closes the second dust outlet 24, it moves toward the inlet end 341. When the second blocking member 421 opens the second dust outlet 24, it moves away from the inlet end 341. In this way, the second blocking member 421 is linearly movable at the outlet end 342 of the dust collection hopper 34, making it suitable for opening and closing the smaller second dust outlet 24. It also prevents interference with the movement of the first blocking member 411, preventing any jamming of the two movements.

[0083] Optionally, the limiting portion 412 is an abutment block provided on the inner side of the first blocking member 411. When the first blocking member 411 closes the first dust outlet 23, the abutment block is at least partially inserted into the dust collection channel 340 and abuts against the second blocking member 421. In this way, when the first blocking member 411 and the second blocking member 421 are both in the closed position, the overall axial size of the dust cup body 10 can be reduced, and the dust cup body 10 has a smooth and beautiful appearance, which is easy to clean and maintain.

[0084] Please continue reading Figure 4 、 Figure 6 、 Figure 7 and Figure 9The second sealing structure 42 also includes a mounting sleeve 422 and a spring 423 fixed within the dust hopper 34. The mounting sleeve 422 has a mounting slot 420 extending axially and opening toward the outlet end 342. The second sealing member 421 includes a rod 4211 and a sealing head 4212. One end of the rod 4211 is axially movably inserted into the mounting slot 420. The spring 423 is disposed within the mounting slot 420 and abuts between the mounting sleeve 422 and the rod 4211. The sealing head 4212 is disposed at the end of the rod 4211 near the outlet end 342 and is used to seal the second dust outlet 24 when the second sealing member 421 moves to the closed position. In this embodiment, the mounting sleeve 422 can be connected to the inner wall of the dust hopper 34 via a connecting member extending radially from its outer periphery, thereby forming a hollow channel on its outer periphery for dirt to fall through. The mounting groove 420 serves as a guide for the installation of the spring 423 and the second blocking member 421. The structure is simple and reliable, and can guide the movement direction of the second blocking member 421 and the expansion and contraction direction of the spring 423 to avoid deflection during the opening or closing process, resulting in jamming.

[0085] In order to improve the sealing effect of the second sealing member 421 on the second dust outlet 24, the sealing head 4212 includes a sealing ring 4213 arranged around the outer periphery of the rod 4211. The sealing ring 4213 is made of elastic material, preferably rubber or silicone.

[0086] Preferably, the surface of the sealing ring 4213 facing the inlet end 341 is configured as an arcuate surface that curves toward the inlet end 341 and extends obliquely toward the outlet end 342 in the direction from the inner ring to the outer ring. Thus, when the second sealing member 421 is opened, the arcuate surface guides dirt falling from the second dust outlet 24 downward, minimizing the accumulation of dirt on the sealing ring 4213.

[0087] Based on the above-mentioned second embodiment, the spring 423 in this embodiment constitutes the elastic driving member in the second embodiment, and its function is as described above, which will not be repeated here. Based on the above-mentioned third embodiment, the spring 423 in this embodiment constitutes the elastic retaining member in the third embodiment, and its function is as described above, which will not be repeated here.

[0088] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
