Description

Technical Field

[0001] This invention relates to the field of handheld vacuum cleaner technology, and particularly to a dust collection device and cleaning components. Background Technology

[0002] As people's living standards continue to improve, vacuum cleaners, as a tool for hygiene and cleaning, have become an indispensable appliance in people's daily lives. Among them, handheld vacuum cleaners have the advantages of being small in size, portable, and easy to use, making them more suitable for cleaning smaller spaces, and thus they are loved by the public.

[0003] In related technologies, handheld vacuum cleaners typically include a dust cup and a main unit. The dust cup is used to store dust, hair, and other debris. Specifically, the dust cup includes a cup body and a lid, with the lid closable at the opening of the cup body. This handheld vacuum cleaner can also be used with a dust collection device, which provides dust collection services. Specifically, when the handheld vacuum cleaner is placed on the dust collection device and the dust cup lid is opened, the dust in the dust cup can be collected by the dust collection device. The problem with this type of handheld vacuum cleaner is that the opening and closing of the dust cup lid usually relies on an electromagnetic structure located on the main unit. This makes it difficult to reduce the size and weight of the main unit, affecting the user's handling experience. Summary of the Invention

[0004] The main objective of this invention is to provide a dust collection device that aims to reduce the size and weight of handheld vacuum cleaners, thereby improving the user experience.

[0005] To achieve the above objectives, the dust collection device proposed in this invention is applied to a handheld vacuum cleaner. The dust collection device includes a body and a closing structure; wherein...

[0006] The body has a second dust collection chamber. The body can be used to place a handheld vacuum cleaner. When the handheld vacuum cleaner is placed on the body and the dust cup lid of the handheld vacuum cleaner is open, the second dust collection chamber is connected to the dust cup of the handheld vacuum cleaner.

[0007] The closing structure includes a trigger element, which is movably disposed within the body. The trigger element has a first position and a second position.

[0008] When the trigger moves from the second position to the first position, the trigger can drive the lid of the handheld vacuum cleaner's dust cup to move from the open state to the closed state.

[0009] In one embodiment, the lid closing structure further includes a drive assembly configured to drive the trigger to remain in the second position when the handheld vacuum cleaner is placed on the body, wherein the trigger can avoid the cup lid in the open state when it is in the second position;

[0010] The drive component also provides a driving force to the trigger to keep the trigger in the first position.

[0011] In one embodiment, the drive assembly includes a mounting base and a first reset member. The mounting base is slidably disposed on the body, and the mounting base can slide in a first direction under the push of the handheld vacuum cleaner and slide in a second direction under the drive of the first reset member; wherein,

[0012] When the mounting base slides along the first direction, the mounting base drives the trigger to move to the second position;

[0013] When the mounting base slides along the second direction, the mounting base drives the trigger to move toward the first position.

[0014] In one embodiment, the trigger is rotatably connected to the mounting base.

[0015] In one embodiment, the body is provided with a stop structure, a first end of the trigger extends toward the stop structure and is connected to the stop structure, and a second end of the trigger extends away from the stop structure;

[0016] When the mounting base slides, the second end of the trigger can swing to avoid the dust cup lid or drive the dust cup lid to close.

[0017] In one embodiment, the drive assembly further includes a second reset member, which provides a reset force to the trigger member to cause the trigger member to have a tendency to rotate toward a first position.

[0018] In one embodiment, at least one of the first reset member and the second reset member is configured as an elastic member.

[0019] In one embodiment, the body is further provided with a lid opening structure, which is configured to trigger the lid to open when the handheld vacuum cleaner is placed on the body.

[0020] In one embodiment, the body further includes a dust collection channel, one end of which forms a plug-in interface, and the other end communicates with the second dust collection chamber, the plug-in interface being for the handheld vacuum cleaner to be inserted;

[0021] The opening structure and the closing structure are arranged opposite to each other within the dust collection channel.

[0022] The present invention also proposes a cleaning component, including a handheld vacuum cleaner and a dust collection device as described in any of the preceding claims;

[0023] The handheld vacuum cleaner includes a dust cup, which includes a cup body, a cup lid, and a locking structure. The cup body has a first dust collection chamber with a first opening. The cup lid is detachably disposed at the first opening and has an open state with the first opening open and a closed state with the first opening closed. When the cup lid is in the closed state, the locking structure locks the cup lid.

[0024] When the handheld vacuum cleaner is placed on the dust collection device, the opening structure of the dust collection device can trigger the locking structure to unlock the cup lid, so that the first opening and the second dust collection chamber can communicate.

[0025] It is understood that the dust collection device of this application, by setting a movable trigger on the body and configuring the trigger to move the dust cup lid of the handheld vacuum cleaner from an open state to a closed state when it moves from a second position to a first position, can automatically close the dust cup lid as the handheld vacuum cleaner is removed from the dust collection device. This eliminates the need for complex electromagnetic structures on the handheld vacuum cleaner to achieve automatic dust cup lid closure, thus contributing to the lightweight and miniaturized design of the handheld vacuum cleaner and improving its battery life. Furthermore, by placing the lid-closing structure on the dust collection device, the larger space of the dust collection device reduces the size requirement of the lid-closing structure, thereby reducing the production cost of the lid-closing structure and consequently lowering the production cost of the cleaning components. Therefore, compared to traditional dust collection devices, this method offers advantages such as reducing the size and weight of handheld vacuum cleaners, improving user experience, and lowering production costs.

[0048] This invention proposes a cleaning component.

[0049] In embodiments of the present invention, such as Figures 1 to 15 As shown, the cleaning assembly includes a handheld vacuum cleaner 100 and a dust collection device 200.

[0050] The handheld vacuum cleaner 100 includes a negative pressure duct (not shown), which has an air inlet (not shown) and an air outlet (not shown). A first negative pressure generating device (not shown) is installed in the negative pressure duct, which generates a suction airflow from the air inlet to the air outlet. The handheld vacuum cleaner 100 includes a main unit 110 and a dust cup 120. The first negative pressure generating device is located in the main unit 110, and the dust cup 120 is installed in the main unit 110. A partial negative pressure duct is formed within the dust cup 120, and an air filter 123 is installed within the dust cup 120. The air filter 123 filters dust, hair, and other debris from the suction airflow, and the filtered dust, hair, and other debris are collected in the dust cup 120. Typically, the air filter 123 includes at least one of a cyclone separator, a filter sponge, and a HEPA filter.

[0051] Specifically, the dust cup 120 includes a cup body 121, a cup lid 122, and a locking structure 130. The cup body 121 has a first dust collection chamber 121a with a first opening 121b. The cup lid 122 is rotatably mounted on the cup body 121 to open and close the first opening 121b. Specifically, the cup lid 122 has an open state with the first opening 121b open and a closed state with the first opening 121b closed. In other embodiments, the cup lid 122 may also be slidably or retractably mounted on the cup body 121.

[0052] The locking structure 130 is configured to lock the cup lid 122 when the first opening 121b is closed.

[0053] Specifically, the first dust collection chamber 121a is used to accommodate the air filter device 123 and to store the waste filtered by the air filter device 123. The first opening 121b is the mouth of the dust cup 120 and can be used to empty the dust collected in the cup body 121. Optionally, to facilitate the user's emptying of the waste in the dust cup 120, the first opening 121b can be located at the lower end of the dust cup 120. Here, the lower end refers to the end of the cup body 121 facing away from the main unit 110. Of course, in other embodiments, the first opening 121b can also be located on the side wall of the cup body 121. After the cup lid 122 is locked by the locking structure 130, the first opening 121b is in the closed state, at which time the dust cup 120 can be used to store waste.

[0054] Specifically, the dust collection device 200 includes a body 210 and a closing structure 220. The body 210 has a dust collection channel 213, a second dust collection chamber 211, and a second opening 212 communicating with the second dust collection chamber 211. One end of the dust collection channel 213 forms a connector 214, and the other end communicates with the second opening 212. The connector 214 allows the handheld vacuum cleaner 100 to be inserted. When the handheld vacuum cleaner 100 is placed on the body 210 and the lid 122 of the dust cup 120 is open, the second opening 212 can communicate with the first opening 121b. It is worth noting that the design of this application is not limited to this. In some embodiments, the handheld vacuum cleaner 100 may not be inserted into the dust collection channel 213, but a placement structure may be provided on the body 210 for placing the handheld vacuum cleaner 100.

[0055] The cover closing structure 220 includes a trigger 221, which is movably disposed on the body 210. The trigger 221 has a first position and a second position.

[0056] When the trigger 221 is in the second position, the trigger 221 can avoid the cup lid 122 which is in the open state;

[0057] When the trigger 221 moves from the second position to the first position, the trigger 221 can drive the cup lid 122 of the handheld vacuum cleaner 100 to move from the open state to the closed state.

[0058] Specifically, when the handheld vacuum cleaner 100 is placed on the body 210 of the dust collection device 200, the lid 122 of the dust cup 120 can move to the open state. At the same time, the trigger 221 can move to the second position to avoid the lid 122 in the open state. At this time, the first opening 121b and the second opening 212 are connected, and dust, hair and other debris in the first dust collection chamber 121a can enter the second dust collection chamber 211 through the first opening 121b and the second opening 212, thus completing the emptying of the debris in the cup 121.

[0059] When the handheld vacuum cleaner 100 is removed from the dust collection device 200, the trigger 221 can move from the second position to the first position to drive the cup lid 122 of the handheld vacuum cleaner 100 from the open state to the closed state. This allows the dust cup 120 lid 122 to automatically close simultaneously with the removal of the handheld vacuum cleaner 100 from the dust collection device 200. Thus, there is no need to incorporate complex electromagnetic structures on the handheld vacuum cleaner 100 to achieve automatic closing of the dust cup 120 lid 122, which helps to achieve a lightweight and miniaturized design of the handheld vacuum cleaner 100 and improves its battery life. Furthermore, by placing the closing structure 220 on the dust collection device 200, the larger space in the dust collection device 200 reduces the size requirement for the closing structure 220, thereby reducing the production cost of the closing structure 220 and consequently lowering the production cost of the cleaning components.

[0060] Furthermore, when the cleaning equipment is placed on the dust collection equipment 200, the first opening 121b and the second opening 212 are arranged opposite to each other.

[0061] In some embodiments, when the cleaning device is placed on the dust collection device 200, the first opening 121b is located above the second opening 212. At this time, if the first opening 121b and the second opening 212 are connected, the garbage in the first dust collection chamber 121a can automatically fall into the second dust collection chamber 211 under the action of gravity.

[0062] In other embodiments, the second dust collection chamber 211 further includes a third opening (not shown), and the dust collection device 200 further includes a second negative pressure generating device (not shown), which can generate a suction airflow from the second opening 212 to the third opening. Based on the second negative pressure generating device, when the first opening 121b is connected to the second opening 212, regardless of whether the first opening 121b is located above the second opening 212, the suction airflow generated by the second negative pressure generating device can draw the debris in the first dust collection chamber 121a into the second dust collection chamber 211, thereby emptying the debris in the dust cup 120.

[0063] It is worth noting that, based on the dust collection device 200 including the second negative pressure generating device, if the first opening 121b is located above the second opening 212, then after the first opening 121b and the second opening 212 are connected, the debris in the first dust collection chamber 121a can more fully enter the second dust collection chamber 211 under the combined action of suction and gravity. That is, it is beneficial to improve the cleaning effect of the dust collection device 200 on the dust cup 120.

[0064] In some embodiments, the closing structure 220 further includes a drive assembly 222 configured to drive the trigger 221 to remain in a second position when the handheld vacuum cleaner 100 is placed on the body 210. Specifically, when the handheld vacuum cleaner 100 is placed on the body 210, the drive assembly 222 can be pushed by the handheld vacuum cleaner 100, and the drive trigger 221 moves from a first position to a second position to avoid the open cup lid 122, thereby allowing the cup lid 122 of the dust cup 120 to open smoothly.

[0065] Furthermore, the drive assembly 222 also provides a driving force to the trigger 221, which enables the trigger 221 to remain in the first position. That is, under the drive of the drive assembly 222, the trigger 221 can always be in the first position. In this way, when the user removes the handheld vacuum cleaner 100 from the dust collection device 200, the trigger 221 can move to the first position immediately, thereby promptly closing the cup lid 122 of the dust cup 120.

[0066] It is understood that the drive component 222 can drive the trigger 221 to move between a first position and a second position, and the drive component 222 can be linked with the handheld vacuum cleaner 100 so that when the handheld vacuum cleaner 100 is placed on the dust collection device 200, the trigger 221 is driven to move to the second position and remain there, and when the handheld vacuum cleaner 100 is removed from the dust collection device 200, the trigger 221 is driven to move to the first position and remain there. In this way, the position of the trigger 221 can be changed in a timely manner according to the state of the handheld vacuum cleaner 100 on the dust collection device 200, so that the trigger 221 can complete actions such as avoidance and closing the lid in a timely manner. In this way, not only can the dust collection efficiency and lid closing efficiency of the dust collection device 200 on the handheld vacuum cleaner 100 be improved, but the completion rate of dust collection and lid closing of the handheld vacuum cleaner 100 by the dust collection device 200 can also be guaranteed. Of course, the design of this application is not limited to this. In other embodiments, the drive component 222 can also be configured to actively drive the trigger 221 to move between the first position and the second position. For example, the drive component 222 can be configured to include a sensor and a motor. The sensor can sense the state of the handheld vacuum cleaner 100 on the dust collection device 200 (such as dust collection state, placement state, removal state, etc.) to generate a corresponding sensing signal. The motor can drive the trigger 221 to move between the first position and the second position according to the sensing signal of the sensor.

[0067] In some embodiments, the drive assembly 222 includes a mounting base 2221 and a first reset member 2222. The mounting base 2221 is slidably disposed on the body 210. The mounting base 2221 can slide in a first direction under the push of the handheld vacuum cleaner 100 and slide in a second direction under the drive of the first reset member 2222.

[0068] When the mounting base 2221 slides along the first direction, the mounting base 2221 drives the trigger 221 to move to the second position;

[0069] When the mounting base 2221 slides along the second direction, the mounting base 2221 drives the trigger 221 to move to the first position.

[0070] Specifically, when the handheld vacuum cleaner 100 is placed on the body 210, the weight of the body 210 on the mounting base 2221 is greater than the reset force provided by the first reset member 2222, or the mounting base 2221 is only pushed by the body 210 and not by the reset force provided by the first reset member 2222. At this time, the mounting base 2221 slides in the first direction under the push of the handheld vacuum cleaner 100, and drives the trigger member 221 to move to the second position until the trigger member 221 moves to the second position. Conversely, during the process of removing the handheld vacuum cleaner 100 from the body 210, if the pushing force of the body 210 on the mounting base 2221 is less than the reset force provided by the first reset member 2222, or if the mounting base 2221 is only subjected to the reset force provided by the first reset member 2222, then the mounting base 2221 slides in the second direction under the drive of the first reset member 2222, so as to drive the trigger member 221 to move to the first position until the trigger member 221 moves to the first position.

[0071] It can be understood that, through the above structure, the position of the trigger 221 can change as the handheld vacuum cleaner 100 is placed on the dust collection device 200.

[0072] It is worth noting that the design of this application is not limited to this. In other embodiments, the mounting base 2221 may also be configured to be rotatably connected to the body 210.

[0073] In some embodiments, the first reset member 2222 is configured as an elastic member. Specifically, the elastic member is a spring disposed between the mounting base 2221 and the body 210. During the process of removing the handheld vacuum cleaner 100 from the body 210, the mounting base 2221 can slide in the second direction under the action of the spring elastic force. Of course, the design of this application is not limited to this. In other embodiments, the elastic member can also be configured as an elastic rope, an elastic pad, a spring sheet, etc. It is worth noting that in other embodiments of this application, the first reset member 2222 can also be configured as other structures, such as a magnetic structure. In this case, a magnetic structure is also provided on the mounting base 2221. The first reset member 2222 and the magnetic structure on the mounting base 2221 repel each other, thereby generating a repulsive force. Under the action of this repulsive force, the mounting base 2221 can also slide in the second direction. In some embodiments, the first reset member 2222 can also be configured as a power member such as a motor, cylinder, or hydraulic cylinder. These power members can provide power to actively drive the mounting base 2221 to slide in the second direction.

[0074] Specifically, the body 210 is provided with a positioning post 216, and the mounting base 2221 is provided with a mounting through hole 2225. The mounting base 2221 is slidably connected to the positioning post 216 through the mounting through hole 2225, and the elastic element is sleeved on the positioning post 216. By providing the positioning post 216, the sliding direction of the mounting base 2221 can be restricted, while the elastic deformation direction of the elastic element can be restricted, thereby enabling the elastic element to provide directional elastic force to drive the mounting base 2221 to slide in the second direction. In addition, the positioning post 216 can also improve the sliding stability of the mounting base 2221.

[0075] In some embodiments, the handheld vacuum cleaner 100 is placed on the dust collection device 200 along the vertical direction of the body 210. Correspondingly, the mounting base 2221 also slides vertically. When the handheld vacuum cleaner 100 is placed on the dust collection device 200, the mounting base 2221 slides downward; when the handheld vacuum cleaner 100 is removed from the dust collection device 200, the mounting base 2221 slides upward. This configuration, where the sliding direction of the mounting base 2221 is consistent with the placement direction of the handheld vacuum cleaner 100, reduces the space reserved in the body 210 for the sliding of the mounting base 2221, thereby helping to reduce the size of the body 210.

[0076] It is worth noting that the design of this application is not limited to this. In other embodiments, the mounting base 2221 may also be configured to slide laterally along the body 210. In some embodiments, the mounting base 2221 may also be configured to be rotatably connected to the body 210, etc.

[0077] In some embodiments, the body 210 is provided with a limiting groove 217, and the mounting base 2221 is slidably mounted in the limiting groove 217. One side wall of the limiting groove 217 is provided with a clearance opening (not shown), from which the trigger 221 extends. The clearance opening can avoid the trigger 221, allowing it to move freely. It can be understood that by providing the limiting groove 217, the sliding direction of the mounting base 2221 can be further restricted, thereby improving the stability of the closing structure 220. Furthermore, the limiting groove 217 also provides an installation position for the mounting base 2221, facilitating the assembly between the closing structure 220 and the body 210.

[0078] In some embodiments, the trigger 221 is rotatably connected to the mounting base 2221. Thus, the mounting base 2221 can rotate while sliding. This arrangement allows the trigger 221 to change position promptly to accommodate the handheld vacuum cleaner 100's placement and removal, and also saves space within the body 210, thereby reducing the overall size of the body 210. Furthermore, placing the trigger 221 on the mounting base 2221 facilitates the installation and removal of the cover structure 220 from the body 210. Of course, the design of this application is not limited to this; in other embodiments, the trigger 221 is also slidably connected to the mounting base 2221. In some embodiments, the trigger 221 may also be disposed on the body 210, rotatably connected to the body 210, or slidably connected to the body 210, etc.

[0079] In some embodiments, the body 210 is provided with a stop structure 230, the first end 2211 of the trigger member 221 extends toward and connects to the stop structure 230, and the second end 2212 of the trigger member 221 extends away from the stop structure 230. Specifically, the stop structure 230 is a boss protruding from the inner wall of the dust collection channel 213. Further, when the mounting base 2221 slides along the first direction and the second direction, the second end 2212 of the trigger member 221 can swing to avoid the cup lid 122 of the dust cup 120 or drive the cup lid 122 of the dust cup 120 to close.

[0080] Specifically, by providing a stop structure 230 on the body 210, it can cooperate with the mounting base 2221 to drive the trigger 221 to swing, thereby enabling the trigger 221 to rotate between the first position and the second position.

[0081] In some embodiments, the second end 2212 of the trigger 221 has a protruding abutment 2213, which can push the lid 122 of the dust cup 120 to close. By providing the abutment 2213, the distance between the trigger 221 and the lid 122 can be shortened, so that the trigger 221 can drive the lid 122 to close. Optionally, the abutment 2213 can be configured as a semi-cylindrical structure.

[0082] In some embodiments, the drive assembly 222 further includes a second reset member 2223, which provides a reset force to the trigger member 221, causing the trigger member 221 to have a tendency to rotate toward a first position. It can be understood that by providing the second reset member 2223, on the one hand, it can cooperate with the first reset member 2222 to ensure that the trigger member 221 can be accurately reset to the first position, thereby ensuring the closure of the cup lid 122; on the other hand, it allows the first end 2211 of the trigger member 221 to only abut against the abutment structure 230 without being hinged to it. Thus, the closing structure 220 can be removed entirely from the body 210, facilitating the assembly and disassembly of the closing structure 220 from the body 210, and simplifying the production of the closing structure 220. Of course, the design of this application is not limited to this. In other embodiments, the second reset member 2223 may not be provided. Instead, the first end 2211 of the trigger member 221 may be rotatably connected to the body 210. In this case, when the mounting base 2221 slides, the mounting base 2221 may also drive the trigger member 221 to rotate around the hinge axis between the first position and the second position.

[0083] In some embodiments, the second reset member 2223 is configured as an elastic member. For example, the elastic member can be a torsion spring sleeved on the rotating shaft of the trigger member 221, or a tension spring or torsion spring with its two ends connected to the trigger member 221 and the mounting base 2221 respectively. Of course, the design of this application is not limited to this; in other embodiments, the elastic member can also be configured as an elastic rope, elastic pad, spring sheet, or other structures. It is worth noting that in some embodiments, the second reset member 2223 can also be configured as other structures, such as two magnetically repelling or attracting elements. In this case, the repulsive or attractive force between the two magnetic elements can be used to give the trigger member 221 a tendency to rotate towards the first position.

[0084] Specifically, when the second reset member 2223 is configured as a torsion spring, the first leg 2223a of the torsion spring abuts against the mounting base 2221, and the second leg 2223b of the torsion spring abuts against the first end 2211 of the trigger member 221. The first leg 2223a provides support for the second leg 2223b so that the second leg 2223b drives the trigger member 221 to rotate to the first position.

[0085] In some embodiments, a handle 2224 is provided on the mounting base 2221. The handle 2224 facilitates the installation and removal of the cover structure 220 on the body 210, thereby aiding in the assembly and subsequent maintenance of the dust collection equipment 200.

[0086] In some embodiments, the body 210 is further provided with a lid opening structure 240, which is configured to trigger the cup lid 122 to open when the handheld vacuum cleaner 100 is placed on the body 210. Further, the lid opening structure 240 and the lid closing structure 220 are disposed opposite to each other in the dust collection channel 213 of the body 210.

[0087] Specifically, the opening structure 240 is configured to trigger the locking structure 130 to unlock the cup lid 122 when the cleaning device is placed on the dust collection device 200, so that the first opening 121b and the second opening 212 can communicate.

[0088] Specifically, when the cup lid 122 is unlocked, it can be opened under the action of a driving force, which can be at least one of gravity, elastic force, magnetic force, and suction force. Regarding the specific application of the above four driving forces, this application provides the following embodiments for illustration:

[0089] In some embodiments, if the cleaning device is placed on the dust collection device 200, the first opening 121b is located above the second opening 212, and the cup lid 122 is rotated downward to open the first opening 121b, then after the cup lid 122 is unlocked, the cup lid 122 can automatically open under the action of gravity.

[0090] In some embodiments, if the dust collection device 200 is equipped with a second negative pressure generating device, and the cup lid 122 rotates away from the cup body 121 to open the first opening 121b, then after the cup lid 122 is unlocked, the cup lid 122 can automatically open under the suction force of the second negative pressure generating device. Wherein, if the cleaning device is placed on the dust collection device 200, the first opening 121b is located above the second opening 212, and the cup lid 122 rotates downwards to open the first opening 121b, then the cup lid 122 can open under the combined action of gravity and suction force.

[0091] In some embodiments, if the cup lid 122 rotates to open the first opening 121b, an elastic element can be provided between the cup lid 122 and the cup body 121. This elastic element generates an elastic force that drives the cup lid 122 to open when it is closed. Therefore, when the cup lid 122 is unlocked, it will automatically open under the elastic force provided by the elastic element. Specifically, if the cup lid 122 rotates downwards to open the first opening 121b, it will open under the combined action of gravity and the elastic force after being unlocked. Conversely, if the cup lid 122 rotates upwards to open the first opening 121b, the elastic force of the elastic element will overcome the gravity of the cup lid 122 to open it after it is unlocked.

[0092] In some embodiments, if the cup lid 122 rotates to open the first opening 121b, a magnetic structure (such as magnets on both the cup lid 122 and the cup body 121) can be provided between the cup lid 122 and the cup body 121. This magnetic structure generates a magnetic force that drives the cup lid 122 to open when it is closed. Therefore, when the cup lid 122 is unlocked, it will automatically open under the magnetic force provided by the magnetic structure. Specifically, if the cup lid 122 rotates downwards to open the first opening 121b, the weight of the cup lid 122 and the magnetic force of the magnetic component work together to open the cup lid 122 after it is unlocked. Conversely, if the cup lid 122 rotates upwards to open the first opening 121b, the magnetic force of the magnetic structure overcomes the weight of the cup lid 122 after it is unlocked, thus opening the cup lid 122.

[0093] In some embodiments, if the cup lid 122 slides to open the first opening 121b, an elastic element or a magnetic structure can be provided between the cup lid 122 and the cup body 121. When the cup lid 122 is unlocked, the elastic force of the elastic element or the magnetic force of the magnetic structure can be used to drive the cup lid 122 to slide relative to the lid body to open the first opening 121b.

[0094] It is understood that the cleaning component of this application, by setting an opening structure 240 in the dust collection device 200, triggers the locking structure 130 to unlock when the cleaning device is placed on the dust collection device 200. Thus, through the cooperation of the opening structure 240 and the closing structure 220, the dust cup 120 lid 122 can be automatically opened and closed, thereby greatly simplifying the user's operation process and significantly improving the user experience.

[0095] In some embodiments, the locking structure 130 includes a latch 131, which is movably disposed on the outer side wall of the cup body 121. The latch 131 has a first position for locking the cup lid 122 and a second position for unlocking the cup lid 122. The opening structure 240 can drive the latch 131 to the second position.

[0096] The latch 131 can lock the cup lid 122 by snapping, by inserting, or by magnetic attraction. Those skilled in the art will understand that the specific locking method of the latch 131 can be adapted to the actual product requirements.

[0097] Specifically, by placing the latch 131 on the outer wall of the cup body 121, the lid opening structure 240 can trigger the latch 131 to unlock from the outside of the cup body 121. This not only makes it easier for the lid opening structure 240 to trigger the latch 131, but also improves the reliability of the lid opening structure 240 triggering the latch 131 to unlock. Simultaneously, this arrangement reduces the structural complexity and fitting difficulty of the lid opening structure 240 and the latch 131, thereby reducing the material and assembly costs of the cleaning components. Furthermore, placing the latch 131 on the outer wall of the cup body 121 allows the user to easily unlock and lock the cup lid 122, and avoids the latch 131 occupying space in the first dust collection chamber 121a, thus improving the storage capacity of the dust cup 120. Of course, the design of this application is not limited to this; in other embodiments, the latch 131 can also be placed on the inner wall of the cup body 121, or within the cup body 121, or on the bottom wall of the cup body 121. In addition, in some embodiments, the latch 131 may also be provided on the cup lid 122.

[0098] In some embodiments, the latch 131 is rotatably connected to the cup body 121. In this case, the trigger 221 can trigger the latch 131 to rotate, thereby unlocking the cup lid 122. Specifically, rotatably connecting the latch 131 to the cup body 121 simplifies the structural design of the cup body 121 and facilitates the unlocking of the latch 131 by the lid-opening structure 240. It also facilitates manual unlocking of the cup lid 122 by the user. Of course, the design of this application is not limited to this; in other embodiments, the latch 131 may also be slidably connected to the cup body 121, or retractably disposed on the cup body 121.

[0099] Based on the embodiment where the latch 131 is rotatably connected to the cup body 121, in some embodiments, the latch 131 has a trigger end 131a and a locking end 131b, and the rotation axis of the latch 131 is located between the locking end 131b and the trigger end 131a.

[0100] Specifically, when the latch 131 is in the first position, the locking end 131b is engaged with the cup lid 122; when the latch 131 is in the second position, the locking end 131b is disengaged from the cup lid 122.

[0101] Furthermore, the opening structure 240 can abut against the trigger end 131a to separate the locking end 131b from the cup lid 122. That is to say, the opening structure 240 triggers the locking structure 130 to unlock by abutting the trigger end 131a. This triggering method is simple and easy to implement, which helps to improve the reliability of the lock 131 unlocking.

[0102] Specifically, the rotation axis of the latch 131 is located between its two ends (i.e., the trigger end 131a and the locking end 131b), so that when the latch 131 locks the cup lid 122, the trigger end 131a protrudes relative to the locking end 131b. Thus, when the cleaning device is placed on the dust collection device 200, the opening structure 240 can bypass the locking end 131b and directly contact the trigger end 131a, thereby driving the locking end 131b to separate from the cup lid 122, thus unlocking the cup lid 122. Furthermore, by positioning the rotation axis of the latch 131 between the locking end 131b and the trigger end 131a, the locking end 131b and the trigger end 131a can form a lever with the latch 131's rotation axis as a fulcrum, thus facilitating manual unlocking of the cup lid 122 by the user.

[0103] Of course, the design of this application is not limited to this. In other embodiments, the rotation axis of the latch 131 may also be located at the trigger end 131a of the latch 131. It is worth noting that when the rotation axis of the latch 131 is located at the trigger end 131a of the latch 131, the lid opening structure 240 can separate the locking end 131b from the lid 122 by attracting (e.g., by magnetic attraction) or pushing (inserting into the gap between the locking end 131b and the cup body 121) the locking end 131b.

[0104] Optionally, in an embodiment where the cup lid 122 is rotated downwards to open the first opening 121b, the locking end 131b of the latch 131 is located below the trigger end 131a.

[0105] In some embodiments, the locking structure 130 further includes a third reset member 132, which provides a reset force to the latch 131 to keep the latch 131 in a first position. That is, under the drive of the third reset member 132, the latch 131 can maintain the locked state of the cup lid 122. This improves the reliability of the locking between the cup lid 122 and the cup body 121. Of course, the design of this application is not limited to this. In other embodiments, the third reset member 132 may not be provided between the cup body 121 and the cup lid 122, and the cup lid 122 may be locked solely by the snap-fit ​​engagement between the latch 131 and the cup body 121.

[0106] In some embodiments, the third reset member 132 is configured as an elastic member, which may be a compression spring disposed between the trigger end 131a of the latch 131 and the cup body 121, a tension spring disposed between the locking end 131b of the latch 131 and the cup body 121, or a torsion spring disposed on the rotating shaft of the latch 131.

[0107] In other embodiments, the third reset member 132 may also include two magnetic members, which are respectively disposed on the cup body 121 and the latch 131. The two magnetic members can attract or repel each other to keep the latch 131 in the first position. Here, when the two magnetic members attract each other, the two magnetic members can be configured as two magnets, or a magnet or a magnetic metal; when the two magnetic members repel each other, the two magnetic members are configured as two magnets.

[0108] In some embodiments, the trigger end 131a of the latch 131 has a latch tooth 131c protruding towards the cup lid 122, and one side of the cup lid 122 has a latch tongue 122a protruding towards the latch 131. The latch tooth 131c engages with the lower side of the latch tongue 122a to lock the cup lid 122.

[0109] Furthermore, the latch 122a has a guide surface (not shown) on the side facing the cup body 121, which can push the latch 131 to rotate to the second position. Specifically, through the guide slope provided on the latch 122a, when the user closes the cup lid 122, the latch 122a can push the latch 131 to turn open. When the latch 122a moves to the upper side of the latch tooth 131c, the latch tooth 131c moves to the lower side of the latch tooth 131c under the action of the elastic force of the latch 131 itself or under the action of the reset force of the third reset member 132, so as to lock the cup lid 122. In this way, the cup lid 122 can be automatically locked to facilitate user operation.

[0110] In some embodiments, the dust collection device 200 further includes a dust collection channel 213, one end of which forms an interface 214 and the other end communicates with a second opening 212. When the cleaning device is placed on the dust collection device 200, the dust cup 120 is inserted into the interface 214.

[0111] It is understood that the insertion interface 214 formed by the dust collection channel 213 facilitates the placement of cleaning equipment on the dust collection device 200 and also facilitates the fixing of the cleaning equipment. In addition, the dust collection channel 213 can also prevent the leakage of garbage from the dust cup 120 when it falls out, so as to ensure environmental hygiene.

[0112] In some embodiments, in order to further prevent waste leakage and to improve the sealing of the connection between the cleaning equipment and the dust collection channel 213, the cleaning equipment may be configured to fit tightly against the channel wall of the dust collection channel 213.

[0113] Furthermore, the opening structure 240 is an abutment protrusion extending inward from the channel wall of the dust collection channel 213. It can be understood that, in conjunction with the structure of the latch 131, the latch 131 can be unlocked simply by setting the opening structure 240 to the abutment protrusion. Thus, the structural design of the opening structure 240 is simple, not only cost-effective but also easy to manufacture.

[0114] In some embodiments, the abutment protrusion extends in an arc shape along the extension direction of the dust collection channel 213. This arrangement facilitates the insertion and removal of the dust cup 120 into the insertion interface 214 and helps the locking end 131b of the abutment protrusion to avoid locking the latch 131. Of course, the design of this application is not limited to this; in other embodiments, the abutment protrusion may also be configured as a hemispherical protrusion.

[0115] In some embodiments, the sidewall of the dust collection channel 213 is provided with a relief groove 215 for the relief latch 131, and the abutment protrusion is provided in the relief groove 215. By providing the relief groove 215, it is helpful to achieve a tight fit between the dust collection device 200 and the sealed channel.

[0116] In some embodiments, the dust cup 120 further includes a drive member 140, which provides a driving force to the cup lid 122 to rotate the cup lid 122 in the direction of opening the first opening 121b. That is, under the drive of the drive member 140, the cup lid 122 can remain open. This ensures that the cup lid 122 is in the open state after the latch 131 is unlocked, so that the waste in the dust cup 120 can be transferred to the dust collection device 200. Of course, the design of this application is not limited to this. In other embodiments, the drive member 140 may not be provided between the cup body 121 and the cup lid 122, and the cup lid may open solely by its own weight.

[0117] In some embodiments, the drive member 140 is configured as an elastic member, which may be a compression spring or tension spring disposed between the cup lid 122 and the cup body 121, or a torsion spring disposed on the rotating shaft of the cup lid 122.

[0118] In other embodiments, the drive element 140 may also include two magnetic elements, which are respectively disposed on the cup body 121 and the cup lid 122. The two magnetic elements can attract or repel each other to keep the cup lid 122 in the open state. When the two magnetic elements attract each other, they can be configured as two magnets, or a single magnet or a magnetic metal; when the two magnetic elements repel each other, they are configured as two magnets.

[0119] In some other embodiments, the drive element 140 may also be a counterweight disposed on the cup lid 122.

[0120] In some embodiments, a limiting structure 150 is provided between the cup lid 122 and the cup body 121 to limit the opening angle of the cup lid 122. By setting the limiting structure 150 to limit the opening angle of the cup lid 122, on the one hand, it can prevent the cup lid 122 from colliding with the dust collection channel 213 when it is opened, thereby reducing the wear and tear on the dust collection device 200 and the cleaning device; on the other hand, it can prevent the cup lid 122 from opening too wide, which would affect the user experience.

[0121] In some embodiments, the limiting structure 150 includes an abutment portion 151 on the side of the cup lid 122 away from the latch 131 and a limiting portion 152 on the cup body 121, with the abutment portion 151 and the limiting portion 152 spaced apart. Spacing the abutment portion 151 and the limiting portion 152 ensures the flatness of the end of the dust cup 120 while limiting the rotation angle of the cup lid 122, thereby contributing to improved aesthetics of the cleaning equipment. Of course, the design of this application is not limited to this; in other embodiments, the limiting structure 150 may also be a protrusion on either the cup lid 122 or the cup body 121.

[0122] The present invention also proposes a dust collection device 200, which is applied to a handheld vacuum cleaner 100.
