Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a dust collection station and cleaning equipment. Background Technology

[0002] Generally, dust collection stations are equipped with dust collection components that make the indoor pressure of the dust collection station lower than the outdoor pressure, forming an airflow that draws dust into the dust collection chamber of the dust collection station. The dust collection chamber is equipped with a dust bag, which is used to filter the airflow, intercept dust, allow the airflow to pass through, and allow the airflow to be discharged from the dust collection chamber.

[0003] After a certain period of operation, if the volume or mass of impurities in the dust bag reaches a threshold, the dust bag needs to be replaced or emptied to prevent it from expanding too much and clogging the dust collection chamber, thus hindering airflow. However, during operation, users often forget to reinstall the dust bag after removing it and use the dust collection station directly. Due to the lack of dust bag filtration, when the airflow carries a large amount of dust through the suction assembly, the dust is attracted by the static electricity generated during operation and adheres to the motor of the suction assembly, which can easily cause a short circuit in the motor.

[0004] Therefore, there is an urgent need for a dust collection station and cleaning equipment to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dust collection station and cleaning equipment. The limiting component can indicate that no dust bag has been installed in the dust collection station, ensuring the proper use of the dust collection station and extending the service life of the cleaning equipment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A dust collection station, used for cleaning equipment, characterized in that the dust collection station comprises:

[0008] The shell body and the cover body are provided. The shell body is provided with a dust collection chamber. The dust bag disassembly and assembly port of the dust collection chamber is formed on the surface of the shell body. The cover body is used to open or close the dust bag disassembly and assembly port.

[0009] A limiting component is movably installed on the shell body.

[0010] The dust bag assembly can be installed in the dust collection chamber or removed from the dust bag removal port. When the dust bag assembly is removed, the limiting member switches from a first position to a second position. When the limiting member is in the first position, the dust bag removal port can be closed. When the limiting member is in the second position, at least a portion of the limiting member is located on the movement path of the cover closing the dust bag removal port, thereby preventing the dust bag removal port from closing.

[0011] As a preferred technical solution of the aforementioned dust collection station, the aforementioned limiting member includes a driving part and a limiting part. The aforementioned dust bag assembly can act on the aforementioned driving part, causing the aforementioned limiting member to switch from the aforementioned second position to the aforementioned first position. When the aforementioned limiting member is in the aforementioned first position, the aforementioned limiting part is located in the aforementioned dust collection chamber. When the aforementioned limiting member is in the aforementioned second position, the aforementioned limiting part extends to the aforementioned moving path.

[0012] As a preferred technical solution of the aforementioned dust collection station, the aforementioned limiting member can rotate relative to the aforementioned shell body. When the aforementioned limiting member is in the aforementioned second position, the aforementioned limiting part is placed on the opening end face of the aforementioned dust bag disassembly port.

[0013] As a preferred technical solution for the aforementioned dust collection station, the aforementioned driving part and the aforementioned limiting part are respectively located on both radial sides of the rotation axis of the aforementioned limiting member.

[0014] As a preferred technical solution of the aforementioned dust collection station, the driving part of the aforementioned limiting member is provided with a buffer structure. When the aforementioned dust bag assembly comes into contact with the aforementioned driving part, the aforementioned buffer structure can undergo elastic deformation to the side away from the aforementioned dust bag assembly.

[0015] As a preferred technical solution for the aforementioned dust collection station, the aforementioned limiting part has a groove, and when the aforementioned limiting part is in the aforementioned second position, the opening end face of the aforementioned dust bag disassembly port is inserted into the aforementioned groove.

[0016] As a preferred technical solution of the aforementioned dust collection station, an abutment portion is provided on the inner side of the edge of the aforementioned cover. When the aforementioned limiting member is in the aforementioned second position, the abutment portion can abut against the aforementioned limiting portion.

[0017] As a preferred technical solution of the aforementioned dust collection station, a reset structure is also included. When the aforementioned dust bag assembly is not installed in the aforementioned dust collection chamber, the reset structure enables the aforementioned limiting member to always be located in the aforementioned second position.

[0018] As a preferred technical solution of the above-mentioned dust collection station, it also includes a support frame, which is detachably installed in the dust collection chamber. The support frame includes a first accommodating chamber and a second accommodating chamber. The dust bag assembly is inserted into the first accommodating chamber, and the limiting member is installed in the second accommodating chamber.

[0019] A cleaning device is also provided, including the aforementioned dust collection station.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a dust collection station for cleaning equipment. The cover and the shell body are movably connected. In this embodiment, the cover and the shell body are detachably connected. The cover can be fastened to the shell body in a first direction to close the dust bag opening or detached from the shell body in the first direction to open the dust bag opening. The opening of the dust bag opening is parallel to the first direction. That is, the movement path of the cover to close the dust bag opening can be the movement path of the cover towards the shell body in the first direction. The limiting member is movably connected to the shell body and can move relative to the shell body, switching between a first position and a second position. When the limiting member is in the first position, the limiting member is completely located inside the dust collection chamber. When the limiting member is in the second position, the limiting member is at least partially located on the movement path of the cover to close the dust bag opening, thereby restricting the closure of the dust bag opening. When the dust bag assembly is removed from the dust bag removal port, the limiting member moves from the first position to the second position. The limiting member in the second position is clamped between the cover and the shell body in the first direction, causing the cover and the shell body to always be spaced apart and unable to be connected. This prevents the dust bag removal port from closing, thus reminding the user that the dust collection chamber is currently missing a dust bag assembly. This prevents the dust collection station from being started directly when there is no dust bag, which could cause the motor to short-circuit after accumulating a large amount of dust. This ensures the proper use of the dust collection station and extends the service life of the cleaning equipment. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0043] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] like Figures 1 to 11 As shown, this utility model provides a dust collection station for cleaning equipment. The dust collection station includes a shell body 100, a cover 600, a limiting member 200, and a dust bag assembly. The shell body 100 has a dust collection chamber 110, and the dust bag disassembly / removal opening of the dust collection chamber 110 is formed on the surface of the shell body 100. The cover 600 is used to open or close the dust bag disassembly / removal opening. The limiting member 200 is movably installed on the shell body 100. The dust bag assembly can be installed in the dust collection chamber 110 through the dust bag disassembly / removal opening or removed from the dust bag disassembly / removal opening. When the dust bag assembly is removed, the limiting member 200 switches from a first position to a second position. When the limiting member 200 is in the first position, the dust bag disassembly / removal opening can be closed. When the limiting member 200 is in the second position, at least a portion of the limiting member 200 is located on the moving path of the cover 600 to close the dust bag disassembly / removal opening, thereby preventing the dust bag disassembly / removal opening from closing.

[0047] For example, the cover 600 is movably connected to the shell body 100. In this embodiment, the cover 600 and the shell body 100 are detachably connected. The cover 600 can be fastened to the shell body 100 along the first direction X to close the dust bag opening or disengage from the shell body 100 along the first direction X to open the dust bag opening. The opening of the dust bag opening is parallel to the first direction X. That is, the movement path of the cover 600 to close the dust bag opening can be the movement path of the cover 600 moving towards the shell body 100 along the first direction X. The limiting member 200 is movably connected to the shell body 100 and can move relative to the shell body 100, switching between a first position and a second position. When the limiting member 200 is in the first position, the limiting member 200 is completely located in the dust collection chamber 110. When the limiting member 200 is in the second position, the limiting member 200 is at least partially located on the movement path of the cover 600 to close the dust bag opening, thereby restricting the closure of the dust bag opening. When the dust bag assembly is removed from the dust bag removal port, the limiting member 200 moves from the first position to the second position. The limiting member 200 in the second position is clamped between the cover 600 and the shell body 100 in the first direction X, so that the cover 600 and the shell body 100 are always spaced apart and cannot be connected. As a result, the dust bag removal port cannot be closed, thus reminding the user that the dust collection chamber 110 is currently missing a dust bag assembly.

[0048] In other embodiments, the cover 600 and the shell body 100 are hinged, slidably connected or otherwise movablely connected, which can maintain the connection between the two and have two states: opening and closing the dust bag installation port.

[0049] Optionally, the limiting member 200 includes a driving part 210 and a limiting part 220. The dust bag assembly can act on the driving part 210, causing the limiting member 200 to switch from a second position to a first position. When the limiting member 200 is in the first position, the limiting part 220 is located within the dust collection chamber 110; when the limiting member 200 is in the second position, the limiting part 220 extends into the movement path. Thus, when the dust bag assembly is installed into the dust collection chamber 110, the dust bag assembly can act on the limiting member 200, causing the limiting member 200 to move from the second position to the first position, thereby releasing interference with the closure of the dust bag installation / removal opening. The dust bag assembly and the limiting member 200 are linked; when the dust bag assembly is installed into the dust collection chamber 110, the limiting member 200 switches from the second position to the first position, reducing the need for additional operations on the limiting member 200.

[0050] Optionally, the limiting member 200 can rotate relative to the shell body 100. When the limiting member 200 is in the second position, the limiting part 220 is placed on the opening end face 111 of the dust bag disassembly port.

[0051] For example, the opening of the dust bag assembly / disassembly port faces the first direction X, the dust bag assembly is installed on the housing body 100 along the first direction X, and the rotation axis of the limiting member 200 is perpendicular to the first direction X.

[0052] In one embodiment, the driving part 210 and the limiting part 220 are located on the radial sides of the rotation axis of the limiting member 200, respectively. Specifically, the rotation axis of the limiting member 200 passes through the middle of the limiting member 200, that is, the limiting member 200 forms a lever model. The limiting member 200 forms a driving part 210 and a limiting part 220 on both sides of the rotation axis. When no dust bag assembly is installed in the dust collection chamber 110, the limiting member 200 is in the second position. The limiting part 220 of the limiting member 200 extends out of the dust bag disassembly port to prevent the dust bag disassembly port from closing. The driving part 210 is located on the installation path between the dust bag assembly and the shell body 100. During the process of installing the dust bag assembly in the dust collection chamber 110, the dust bag assembly contacts the driving part 210 of the limiting member 200 and drives the driving part 210 to rotate around the rotation axis to avoid the dust bag assembly. In this way, the limiting part 220 is driven to rotate into the dust collection chamber 110, and the limiting member 200 rotates from the second position to the first position. After the dust bag assembly is taken out, the limiting member 200 switches from the first position to the second position.

[0053] In this embodiment, since the dust bag assembly and the drive unit 210 abut in one direction, the drive unit 210 can only move away from the dust bag assembly. Therefore, a functional component such as an elastic member 400 or a magnetic member is needed as a reset structure so that the limiting member 200 always has a tendency to move from the first position to the second position. When the dust bag assembly is taken out, the limiting member 200 can be driven to move to the second position.

[0054] In this embodiment, the driving part 210 of the limiting member 200 is provided with a buffer structure. When the dust bag assembly comes into contact with the driving part 210, the buffer structure can elastically deform away from the dust bag assembly. In this way, the buffer structure can absorb part of the impact force generated between the dust bag assembly and the limiting member 200 through elastic deformation, reducing excessive compression between the dust bag assembly and the limiting member 200 caused by part processing errors or mechanism assembly errors.

[0055] like Figure 11 As shown, the limiting member 200 has a waist-shaped through hole 230 as a buffer structure. When the dust bag assembly is squeezed by the limiting member 200, the side wall of the waist-shaped through hole 230 adjacent to the dust bag assembly can deform to the side away from the dust bag assembly, that is, into the waist-shaped through hole 230.

[0056] The buffer structure can also be a rubber pad or similar material disposed on the surface of the limiting member 200, or the limiting member 200 itself can be made of rubber. This is prior art and will not be described in detail here.

[0057] In this embodiment, the limiting part 220 has a groove 221. When the limiting member 200 is in the second position, the opening end face 111 of the dust bag disassembly port is partially inserted into the groove 221. In this way, stress concentration caused by line contact between the limiting member 200 and the opening end face 111 of the dust bag disassembly port can be avoided.

[0058] Preferably, the outline of the inner wall of the groove 221 is adapted to the outline of the opening end face 111 of the dust bag removal port to form a surface contact, so that the inner wall of the groove 221 and the opening end face 111 of the dust bag removal port can fit together further.

[0059] In another embodiment, the dust bag assembly is provided with a first engaging portion, and the limiting member 200 is provided with a second engaging portion. The first and second engaging portions can engage or disengage with each other. When the dust bag assembly is removed from the dust collection chamber 110, the first and second engaging portions can engage with each other. The dust bag assembly drives the limiting member 200 from a first position to a second position through this engagement, causing at least a portion of the limiting member 200 to extend out of the dust bag disassembly / removal opening, preventing the dust bag disassembly / removal opening from closing. When the dust bag assembly is installed in the dust collection chamber 110, the first and second engaging portions can engage with each other. The dust bag assembly drives the limiting member 200 from the second position to the first position through this engagement, causing the limiting member 200 to retract completely into the dust collection chamber 110, no longer interfering with the closure of the dust bag disassembly / removal opening.

[0060] It should be noted that the first meshing part and / or the second meshing part can be a continuous tooth structure.

[0061] In this embodiment, since the dust bag assembly and the limiting member 200 can be driven bidirectionally, the switching of the limiting member 200 between the first position and the second position can be driven by the dust bag assembly. Therefore, the reset structure can be a functional component such as an elastic member 400 or a magnetic member, or it can be a snap-fit ​​structure. That is, when the dust bag assembly is removed, the dust bag assembly drives the limiting member 200 to move to the second position and fixes it to the shell body 100 through the snap-fit ​​structure to maintain it in the second position. When the dust bag assembly is installed into the dust collection chamber 110, the dust bag assembly drives the limiting member 200, the snap-fit ​​structure is released, and the limiting member 200 returns to the first position.

[0062] For example, the opening of the dust bag assembly / disassembly port faces the first direction X. The dust bag assembly is mounted on the housing body 100 along the first direction X, and the rotation axis of the limiting member 200 is parallel to the first direction X. The limiting member 200 includes a driving part 210 and a limiting part 220. A first threaded structure is provided on the outer peripheral side of the driving part 210, and the limiting part 220 is formed on the radial sidewall of the driving part 210 in an L-shape. A second threaded structure is provided on the outer side of the dust bag assembly. The first threaded structure and the second threaded structure can engage or disengage. When storing or retrieving the dust bag assembly, the dust bag assembly drives the limiting member 200 to rotate through the engagement of the threaded structures, switching between the first position and the second position.

[0063] Optionally, the limiting member 200 can translate relative to the shell body 100 to switch between a first position and a second position.

[0064] In one embodiment, the opening of the dust bag assembly / disassembly port faces a first direction X. The dust bag assembly is installed on the housing body 100 along the first direction X. The limiting member 200 moves along a second direction, which is perpendicular to the first direction X. The dust bag assembly and / or the limiting member 200 are provided with guide surfaces. When the limiting member 200 is in the first position, at least a portion of its body is located on the installation path between the dust bag assembly and the housing body 100. When the dust bag assembly is installed in the dust collection chamber 110, the limiting member 200 is in the first position, located on the side of the dust bag assembly facing the dust bag assembly / disassembly port. When the dust bag assembly is removed from the dust collection chamber 110, the dust bag assembly presses against the limiting member 200 through the guide surface. The guide surface converts part of the force in the first direction X into a force in the second direction, causing the limiting member 200 to move to its second position along the second direction.

[0065] In this embodiment, the reset structure is a snap-fit ​​structure that constrains the limiting member 200 to the second position.

[0066] In another embodiment, the opening of the dust bag assembly / disassembly port faces the first direction X, the dust bag assembly is installed on the housing body 100 along the first direction X, and the limiting member 200 moves along the first direction X. The limiting member 200 includes a driving part 210 and a limiting part 220. The driving part 210 and the limiting part 220 are rotatably connected, and the rotation axis is perpendicular to the first direction X and the second direction. When a dust bag assembly is installed in the dust collection chamber 110, the driving part 210 is located at the far end of the dust bag disassembly port in the first direction X. The angle between the limiting part 220 and the driving part 210 is α, which satisfies α > 90°. When the dust bag assembly is removed from the dust collection chamber 110, the driving part 210 moves along the first direction X towards the dust bag disassembly port. The limiting part 220 extends out of the dust bag disassembly port. Due to the lack of limiting by the side wall of the dust collection chamber 110, the limiting part 220 rotates with the driving part 210 under the action of the reset structure. At this time, the angle between the limiting part 220 and the driving part 210 is β, which satisfies β ≤ 90°. The limiting part 220 overlaps the opening end face 111 of the dust bag disassembly port.

[0067] In this embodiment, the drive unit 210 has a guide groove. In the first direction X, one end of the guide groove is closed, and the other end is open. The opening can be elastically deformed. The dust bag assembly can be inserted into the guide groove. When the dust bag assembly is installed into the dust collection chamber 110, the dust bag assembly enters the guide groove from the opening along the first direction X and can drive the limiting member 200 to move in the first direction X against the closed end of the guide groove. When the dust bag assembly is taken out from the dust collection chamber 110, the dust bag assembly abuts against the opening side of the guide groove along the first direction X and moves to the second position with the limiting member 200. When the limiting member 200 reaches the second position, the limiting member 200 and the shell body 100 remain relatively stationary. The continuous force applied by the dust bag assembly causes the opening of the guide groove to elastically deform, and the dust bag assembly is dislodged from the guide groove.

[0068] Optionally, an abutment portion 610 is provided on the inner edge of the cover 600, which abuts against the limiting portion 220 when the limiting member 200 is in the second position. Preferably, the abutment direction is consistent with the direction in which the cover 600 closes the dust bag opening. This arrangement reduces the length of the limiting member 200 extending out of the dust collection chamber 110, thereby reducing the length of the limiting member 200.

[0069] Optionally, the dust collection station also includes a reset structure. When no dust bag assembly is installed in the dust collection chamber 110, the reset structure ensures that the limiting member 200 is always in the second position. As mentioned above, the reset structure can be a functional component such as an elastic member 400 or a magnetic member that can continuously act on the limiting member 200, or it can be a snap-fit ​​structure used to lock the relative position of the limiting member 200 and the housing body 100. The specific choice can be made according to the driving form of the dust bag assembly and the limiting member 200.

[0070] Optionally, the reset structure includes a drive and a switch. The drive is used to drive the limit member 200 to switch between a first position and a second position. The switch is electrically connected to the drive, and the dust bag assembly can trigger the switch.

[0071] For example, the switch can be a touch switch. When the dust bag assembly is loaded or unloaded into the dust collection chamber 110, the dust bag assembly can trigger the touch switch, thereby activating the drive to control the limiting member 200 to switch between a first position and a second position. The switch can also be an infrared switch, with an infrared receiver and an infrared transmitter installed on opposite sides of the dust collection chamber 110. The infrared transmitter continuously emits light. When the dust collection chamber 110 is empty, the infrared receiver can receive light, and the drive keeps the limiting member 200 in the second position. When the dust collection chamber 110 is filled with a dust bag assembly, the infrared receiver cannot receive light, and the drive drives the limiting member 200 to move to the first position.

[0072] The driving component is selected according to the connection method between the limiting component 200 and the shell body 100. If the limiting component 200 and the shell body 100 rotate relative to each other, the driving component is a motor or other mechanism that can realize rotation. If the limiting component 200 and the shell body move relative to each other, the driving component is a telescopic rod or other mechanism that can realize linear movement.

[0073] Optionally, the dust bag assembly includes a support member 310 and a dust bag. The housing body 100 also has a feed inlet. The support member 310 is installed on the housing body 100. The dust bag is connected to the support member 310 and docks with the feed inlet. A limiting member 200 is installed on the radial side of the support member 310 at the feed inlet and axially at the feed inlet. The limiting member 200 is close to the feed inlet relative to the dust bag. The housing body 100 has a suction channel, which is connected to the dust collection chamber 110 through the feed inlet. The suction assembly inside the housing body 100 can generate suction, allowing dust to enter the dust collection chamber 110 from the feed inlet. The dust is collected by the dust bag, and the airflow is discharged. Installing the limiting member 200 near the feed inlet can reduce the contact between the limiting member 200 and the dust bag, avoiding interference or damage to the dust bag due to movement of the limiting member 200.

[0074] Optionally, the dust collection station also includes a support frame 500, which is detachably installed within the dust collection chamber 110. The support frame 500 includes a first receiving chamber 510 and a second receiving chamber. The dust bag assembly is inserted into the first receiving chamber 510, and the limiting member 200 is installed in the second receiving chamber. By centrally installing the dust bag assembly and the limiting member 200 on the support frame 500, the structural design and processing on the main body 100 can be reduced. Furthermore, if the limiting member 200 is damaged, the dust bag assembly is stuck to the support frame 500 and cannot be easily disassembled, or if the support frame 500 is damaged, the support frame 500 can be directly removed from the main body 100 for easy replacement and maintenance.

[0075] In this embodiment, the support frame 500 is symmetrically provided with sliding grooves, and the support member 310 can be slidably inserted into the sliding grooves. Furthermore, the sliding grooves are provided with strip-shaped protrusions 511, which are used to abut against the support member 310 in the direction of gravity. This can reduce the contact area between the support member 310 and the support frame 500, avoid adhesion, and reduce friction.

[0076] In other embodiments, the sliding grooves on both sides are provided on the shell body 100.

[0077] In other embodiments, the limiting member 200 is rotatably connected to the shell body 100 to form a lever model, with a groove on one side of the shell body 100 and a groove on the other side of the limiting member 200.

[0078] A cleaning device is also provided, including the aforementioned dust collection station. Specifically, when the dust collection station is working, the pressure inside the dust collection chamber 110 is lower than the external pressure, creating a pressure difference that draws external dust into the dust collection chamber 110 and collects it in a dust bag. Therefore, in the working state, the dust collection chamber 110 is a relatively sealed environment, with the cover 600 tightly fastened to the shell body 100, and the cover 600 pressed against the opening end face 111 of the dust bag installation / removal port. If there is a significant gap between the two, it cannot be fixed. When the dust collection chamber 110 is missing a dust bag assembly, when the limiting member 200 is in the second position, the limiting member 200 can be clamped between the cover 600 and the opening end face 111 of the dust bag installation / removal port, preventing it from being fixed. In this way, a missing assembly reminder can be provided, preventing the dust collection station from being started directly when a dust bag is missing, which could cause the motor to short-circuit after absorbing a large amount of dust.

[0079] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
