Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It will be appreciated that in the following embodiments, the descriptions of the various embodiments are emphasized, and that portions of some embodiments that are not described in detail are referred to in this connection. The structures shown in the various embodiments are compatible with each other unless explicitly stated or otherwise functionally and structurally violated or otherwise unrealisable.

It should be understood that, in the following embodiments, "first", "second", and the like are used only for distinguishing each other, and do not represent the degree of importance and order, and the precondition that each other exists, and the like.

It is to be understood that in the following embodiments, "connected", "coupled" and the like include not only direct but also indirect interconnections, unless specifically indicated otherwise.

Referring to fig. 1 to 19, the embodiment of the present application provides a dust collecting device which can be configured in various dust collectors, acarid removers or cleaning robots according to application scenes to provide functions of storing dust and sundries. In the process that dust-containing air flows sucked by various dust collectors, mite-removing machines or cleaning robots and the like enter and leave the dust collecting device, dust, sundries and the like contained in the dust-containing air flows are remained in the dust collecting device, and then the dust-containing air flows become a collection object of the dust collecting device.

In order to accommodate the collected matter of the dust collecting device and the components required for the dust collecting device, the dust collecting device includes a tub 110 having an accommodating space 111, and a release port 112 communicating with the accommodating space 111 is provided on the tub 110 so as to clean the collected matter in the dust collecting device. The tub 110 may be square, rectangular, circular, polygonal, etc. to adapt to different application scenarios or product structural designs, and the present embodiment is not limited thereto.

Meanwhile, the tub 110 is further provided with a cover 120 at the release opening 112, and the cover 120 is connected to the tub 110 and is movable between an open position and a closed position with respect to the tub 110, so as to provide an opening and closing function for the release opening 112, i.e., enable the release opening 112 to be opened or closed. When the cover 120 is at the open position, the release opening 112 is opened by the cover 120, and the collected objects can leave the accommodating space 111 from the release opening 112; when the cover 120 is at the closed position, the release opening 112 is closed by the cover 120, and the collected matter cannot leave the accommodating space 111 from the release opening 112.

Wherein, normally, the release opening 112 is provided at the bottom of the tub 110 to allow the collected matter to exit from the receiving space 111 when cleaning. In other words, when the user cleans the accommodating space 111, the dust collecting device is generally adjusted to a state that the release opening 112 is positioned at the bottom of the tub 110, so that the collected matter leaves the accommodating space 111 due to the gravity. Meanwhile, the cover 120 is also positioned at the bottom of the tub 110 corresponding to the release port 112. Of course, in other embodiments, the release opening 112 may be disposed at other locations than the bottom of the tub 110, so as to be suitable for other product structural designs or to meet the requirements of specific usage scenarios.

In order to facilitate the opening of the cover 120, the dust collecting device is further provided with a release mechanism 130, and the release mechanism 130 is used for moving the cover 120 from the closed position to the open position, so as to open the cover 120 and the release opening 112, so that the collected matter can leave the accommodating space 111 and the accommodating space 111 can be cleaned.

In the conventional dust collecting device, the opening direction of the cover 120 almost directly faces the operation side 113 of the user. When the cover 120 is opened to empty or release the collected matter, since the collected matter is mostly composed of dust or dust, the collected matter leaving the release opening 112 easily drifts toward the operation side 113 of the user, which not only affects the use of the user, but also may pollute the environment or even the dust collecting device.

Accordingly, in the dust collecting device provided in the present embodiment, the cover 120 has a fixed end 122 and a switching end 121, the fixed end 122 is adjacent to the operation side 113 of the tub 110 and is pivotably connected to the tub 110, and the switching end 121 is distant from the operation side 113 with respect to the fixed end 122 and is releasably connectable to the tub 110. In the process that the release mechanism 130 moves the cover 120 from the closed position to the open position, the cover 120 moves from the switch end 121 far from the operation side 113 to the direction of the operation side 113, so that the collector being released can be blocked from drifting toward the operation side 113, and the release opening 112 is more easily aligned with a destination (such as a garbage pool or a garbage can) receiving the collector being released, so as to release the collector more accurately. It can be seen that the cover 120 and the tub 110 are movably connected at a position close to the operation side 113, so that drift of the collected objects to the operation side 113 when the collected objects leave the accommodating space 111 is reduced, and influence on a user of the operation side 113 and the dust collecting device can be avoided.

The operation side 113 is a side of the dust collecting device, which is a side where a user uses the dust collecting device, particularly when cleaning the dust collecting device, that is, a side where the user approaches the user when operating the dust collecting device. For example, the operating side 113 includes a side wall of the barrel that is biased toward the handle 230 and/or the area where the body assembly 210 is located. Generally, various kinds of user operation parts of the dust collecting device are provided at the operation side 113 or at a position close to the operation side 113 so that a user located at the operation side 113 performs a related operation. The user operating parts include various kinds of operating buttons, a handle 230 (see fig. 18), etc., and the related parts of the dust collecting device, such as a battery assembly 220 (see fig. 18), a body assembly 210, etc., are also generally located at the operating side 113. Thus, the prior art has the following problems: the collection drifting toward the user side is liable to affect, for example, cause contamination to various user operation parts and related parts located on the operation side 113, not only reducing cleanliness but also possibly affecting normal use of the various user operation parts and related parts due to accumulation of dust or the like. By the arrangement of the embodiment, the possibility of similar situations can be reduced, and effective use of the dust collecting device and operation experience of a user are further ensured.

The release mechanism 130 has an operating portion 131, and the operating portion 131 may be located at an operating side of the tub 110. The operation unit 131 is an operation structure for a user to operate to start the release mechanism 130, and may be, for example, various operation units such as a voice information receiving unit, an image information receiving unit, a fingerprint information receiving unit, and a mechanical switch button, and specifically may be a sound receiving unit of a microphone, an image capturing unit of a camera, a pressing operation unit of a mechanical switch, etc., which is not limited in this embodiment, and only needs to receive an operation instruction of the user and perform corresponding operation. The user may start the operation of the release mechanism 130 by applying a predetermined signal to the operation portion 131, for example, by sending a corresponding operation instruction through voice, gesture, pressing, etc., so as to enable the cover 120 to move from the closed position to the open position. It should be understood that the operation portion 131 of the release mechanism 130 may not be disposed on the barrel 110, for example, the release mechanism 130 may have a wireless/wired communication structure, and the user may apply a predetermined signal to the mobile terminal and send a corresponding operation instruction to the release mechanism 130 through the wireless/wired communication structure, so that the release mechanism 130 starts to operate.

In some embodiments, the cover 120 is hinged to the tub 110 by an electrical hinge that holds the cover 120 in the open position. The operation portion 131 of the release mechanism 130 may be a voice signal receiving portion, such as a sound receiving portion of a microphone, and the voice signal receiving portion is disposed on the operation side 113 of the tub 110, and the release mechanism 130 starts to operate after the voice signal receiving portion receives a voice signal sent by a user. The release mechanism 130 sends an opening signal to the electric hinge connected with the signal to enable the cover 120 to move from the closed position to the open position; in addition, after a preset operation is applied to the operation part 131, the release mechanism 130 may also send a closing signal to the electric hinge connected with a signal, so as to enable the cover 120 to move from the open position to the closed position.

In order to ensure that the release opening 112 is closed such that the collection does not leave the receiving space 111 by the release opening 112 if not necessary, the dust collecting device may comprise a locking structure 140, the locking structure 140 being adapted to hold the cover 120 in the closed position such that the release opening 112 remains closed. The locking structure 140 may be implemented in various manners, such as a snap-fit structure, a magnetic structure, etc., which is not limited in this embodiment.

In some embodiments, the locking structure 140 is configured to achieve an openable connection between the opening and closing end 121 of the cover 120 and the tub 110, that is, the locking structure 140 is configured to cover and fix the opening and closing end 121 of the cover 120 and the tub 110 in a closed position, that is, to hold the cover 120 in the closed position closing the release opening 112. When the locking structure 140 is in the mated state, the opening and closing end of the cover 120 is fixed to the tub 110, and the cover 120 is located at the closed position; when the locking structure 140 is in a disconnected state, the fixing of the opening and closing end 121 of the cover 120 and the tub 110 is released, and the cover 120 can move to the open position.

After a user applies a preset operation through the operation portion 131, the locking structure 140 can be changed from the mated connection state to the disconnected state through the release mechanism 130, so that the cover 120 can be moved from the closed position to the open position.

In some embodiments, the release mechanism 130 is in signal connection with the locking structure 140, and after a user applies a preset operation to the operation portion 131, the release mechanism 130 sends a signal for releasing the locking structure 140, and the locking structure 140 starts to perform a disengagement action so that the cover 120 can be moved from the closed position to the open position. For example, the locking structure 140 is an electromagnetic adsorption structure, the electromagnetic adsorption structure includes a first electromagnetic adsorption portion located at the switch end 121 of the cover 120 and a second electromagnetic adsorption portion located at a corresponding position of the tub 110, at least one of the first electromagnetic adsorption portion and the second electromagnetic adsorption portion is an electromagnetic structure, and the other electromagnetic adsorption portion may be a magnet, a metal or an electromagnetic structure, and by energizing the electromagnetic structure, a magnetic field can be generated to enable the two electromagnetic adsorption portions to each other, so as to realize the mating connection of the locking structure 140, and hold the cover 120 in the closed position. When the release mechanism 130 sends a signal for releasing the locking structure 140, the electromagnetic structures in the first electromagnetic adsorption portion and the second electromagnetic adsorption portion are powered off, so that the first electromagnetic adsorption portion and the second electromagnetic adsorption portion are separated from each other, that is, the cover 120 can leave the closed position to move towards the open position. As another example, the locking structure 140 includes a claw and a clamping portion driven by a motor or other driving device, the cover 120 can be kept at the closed position by matching the claw and the clamping portion, when the release mechanism 130 sends a signal for releasing the matching to the locking structure 140, the motor or other driving device drives the claw to move to release the matching with the clamping portion, that is, the cover 120 can leave the closed position to move to the open position.

In other embodiments, the release mechanism 130 includes a first moving portion and a second moving portion that are linked, the first moving portion is located on the operation side 113, the second moving portion is located on the cover 120, and the moving directions of the first moving portion and the second moving portion are different.

Illustratively, the release mechanism 130 includes a driving member 132, a transmission member 133, and an unlocking member 150, where the driving member 132 is connected to the transmission member 133 and the driving member 132 can drive the transmission member 133 to move, and the transmission member 133 has or serves as the first moving portion; the unlocking piece 150 is matched with the transmission piece 133, and the transmission piece 133 is provided with or serves as the second movement part; when the driving member 132 moves, the unlocking member 150 can be driven to open the locking structure 140, even if the cover 120 can move from the closed position to the open position.

Details of the construction of the respective components of the dust collecting device will be exemplarily described with reference to fig. 4 to 18.

Referring to fig. 10, a side of the cover 120 near the operation side 113 is the fixed end 122, a side of the cover 120 away from the operation side 113 is the switch end 121, the locking structure 140 is disposed at an end of the switch end 121 of the cover 120 and an end of the tub 110 corresponding to the switch end 121, and the switch end 121 is any side other than the fixed end 122, that is, the switch end 121 is a side away from the operation side 113 relative to the fixed end 122. Wherein, when the locking structure 140 is in the state of being cooperatively connected, the cover 120 is located at the closed position; when the locking structure 140 is in a state of releasing the mating connection, the cover 120 can be moved to the open position.

The unlocking member 150 includes a power portion 151 near the fixed end 122 and a resistance portion 152 near the switch end 121, specifically, the unlocking member 150 may be provided with the power portion 151 near the end of the fixed end 122, and the resistance portion 152 near the end of the switch end 121, where the power portion 151 may be directly or indirectly driven by the driving member 132, and the resistance portion 152 may be synchronously moved when the power portion 151 is driven, so that the locking structure 140 is disengaged from the mating connection.

In some examples, referring to fig. 10, the switch end 121 and the fixed end 122 are opposite ends of the cover 120, and a direction from the fixed end 122 to the switch end 121 is a first direction, and, for example, referring mainly to fig. 1 and 10, the first direction is an X direction in fig. 1 and 10, and the switch end 121 and the fixed end 122 are opposite ends along the X direction; the unlocking member 150 can be indirectly driven by the driving member 132 through the connected transmission member 133 and moves along the first direction, so as to apply a force to the locking structure 140 and enable the cover 120 and the barrel 110 to be separated from each other through the locking structure 140, i.e. the locking structure 140 is opened to change to a state of releasing the matching connection, so that the cover 120 can move from the closed position to the open position.

Specifically, as shown in fig. 4 to 6 and 10 to 17, the dust collecting device includes a locking member 141, and the locking member 141 is rotatably connected to an end portion of the tub 110 at a suction side 114 corresponding to the switch end 121 through a rotation fulcrum portion 1411, wherein the suction side 114 is an opposite side of the operation side 113, and particularly the suction side 114 and the operation side 113 are oppositely disposed along the X direction in fig. 10. An air inlet pipe for sucking foreign matters such as dust and debris into the accommodating space 111 may be generally connected to the suction side 114. Referring to fig. 13 to 17, the switch end 121 of the cover body is provided with an abutting end 1251 corresponding to the free end 1412 of the locking member 141, and the free end 1412 of the locking member 141 and the abutting end 1251 form the locking structure 140, wherein the free end 1412 of the locking member 141 may be hooked so as to abut against the abutting end 1251 and keep the cover body 120 in the closed position.

The unlocking member 150 is disposed on the cover 120, and when the free end 1412 of the locking structure and the abutting section 1251 abut against each other, that is, when the locking structure 140 is in a matched connection state, the resistance portion 152 is located on a side of the free end 1412 of the locking member 141 facing the fixed end 122. The transmission member 133 applies a force to the power portion 151 to move the unlocking member 150 in the first direction, so as to drive the resistance portion 152 to move in the first direction and move the free end 1412 of the locking member 141 in the first direction, that is, rotate the locking member 141 about the rotation fulcrum portion 1411, and make the free end 1412 of the locking member 141 leave a position abutting against the abutting end 1251, and the locking structure 140 changes to a state of releasing the mutual engagement connection, at this time, the cover 120 can move from the closed position to the open position.

The other end of the locking member 141 may further be provided with a retaining member 142, and connected to the tub 110 through the retaining member 142, where the retaining member 142 provides a force against the abutment end 1251 to the free end 1412 of the locking member 141 through the other end of the locking member 141, so that the locking structures 140 can be stably matched with each other. When the resistance portion 152 moves in the first direction and moves the free end 1412 of the locking member 141 in the first direction, the force of the retainer 142 needs to be overcome; when the resistance portion 152 no longer applies force to the free end 1412 of the locking member 141, the retainer 142 may reset the free end 1412. The retainer 142 may be a repulsive magnet, a spring, or the like, which is not limited in this embodiment.

For a more specific description of the cooperation between the unlocking member 150 and the locking structure 140, as shown in fig. 13 to 17, the cover 120 has an unlocking cavity 123 disposed in a circumferential direction, a first supporting section 124 disposed at the switch end 121, and a second supporting section 125 protruding outwards, wherein the lower end of the second supporting section 125 forms the supporting end 1251, and the first supporting section 124 may be perpendicular to the second supporting section 125.

The unlocking chamber 123 may be formed by the cover 120 and the fixing cover 155, the fixing cover 155 is coupled to the outside of the cover 120, and the unlocking chamber 123 is formed between the cover 120 and the fixing cover 155. The fixing cover 155 can facilitate the assembly of the unlocking member 150.

Referring to fig. 10, 18 and 19, the unlocking member 150 is of an annular structure, and is disposed in the unlocking chamber 123, and an end portion of the unlocking member 150 adjacent to the switch end 121 protrudes outwards to form the resistance portion 152, a reset chamber 153 is disposed inside the resistance portion 152 of the unlocking member 150, a first reset member 154 is disposed in the reset chamber 153 along the first direction, and the first reset member 154 includes a first sub-portion that is fixed relative to the unlocking member 150 and the first abutting section 124 extending into the reset chamber 153. Wherein, the first reset element 154 may be a magnetic element, for example, the first sub-portion is two magnets that attract each other; the first restoring member 154 may also be a first elastic restoring member, where the first elastic restoring member may be a spring, and the first sub-portion is two ends of the spring; the first reset element 154 may have other structures, and only needs to achieve the effect of resetting the unlocking element 150, which is not limited in this embodiment.

For a more specific description of the engagement between the unlocking member 150 and the driving member 133, as shown in fig. 4 to 6, 10, and 13 to 19, the unlocking member 150 has a ring structure, and protrudes outward at an end portion near the fixed end 122 to form the power portion 151, an inclined engagement surface 156 is formed between the power portion 151 and the driving member 133, and the power portion 151 and the driving member 133 can be engaged with each other through the engagement surface 156 to move the unlocking member 150 along the first direction, so that the driving member 133 forms the first moving portion, and the unlocking member 150 forms the second moving portion.

For example, when the release opening 112 is directed downward (even though the release opening 112 and the cover 120 are positioned at the bottom of the tub 110) for corresponding operations, the driving direction of the release mechanism 130 is a second direction, which refers to a direction in which the receiving space 111 directs the release opening 112, specifically, when the release opening 112 is directed downward, i.e., a downward direction, i.e., a direction of force F in fig. 1 to 5, for example, please refer mainly to fig. 1 and 10, and a downward direction along the Y axis in the drawings is the second direction. When the driving member 132 drives the transmission member 133 (i.e., the first moving portion) to move in the second direction, the power portion 151 may drive the unlocking member 150 (i.e., the second moving portion) to move in the first direction by gradually tilting the mating surface 156 away from the first direction, and the locking structure 140 may be disengaged, so that the cover 120 may rotate to the open position by gravity. It will be appreciated that in other embodiments, the release opening 112 may not be located in a downward position, and the release mechanism 130 may further include a mechanism for driving the cover 120 to open or otherwise open the cover 120 when the locking structures 140 have been disengaged from each other.

The mating surface 156 is a mating inclined surface of at least one of the power portion 151 and the driving member 132, and the power portion 151 and the driving member 133 are mated with each other through the mating inclined surface to drive the unlocking member 150 to move in the first direction. When the power portion 151 and the transmission member 133 have the mating inclined surfaces, the transmission member 133 drives the unlocking member 150 to move in the first direction more stably and flexibly.

It will be appreciated that in other embodiments, when the interconnection of the locking structure 140 cannot be released by the movement of the locking member 141 in the first direction, but is required to be released by the movement of the locking member 141 in the opposite direction of the first direction, a mating surface inclined in the opposite direction to the previous embodiment may be formed between the power part 151 and the transmission member 133, and the transmission member 133 and the power part 151 may be mated with each other by the mating surface 156 to move the unlocking member 150 in the opposite direction of the first direction. For example, the locking structure 140 may include a first connector disposed at an end of the unlocking member 150 near the opening and closing end 121 and a second connector disposed at an end of the opening and closing end 121 of the tub 110, and the first connector and the second connector may cooperate with each other to connect the locking structure 140 and hold the cover 120 in the closed position. When the transmission member 133 moves in the second direction, the unlocking member 150 can move in the opposite direction of the first direction through the inclined mating surface 156, so that the first connecting member and the second connecting member can be separated from each other, that is, the mating connection of the locking structure 140 is released, and the cover 120 can move toward the opening position. Wherein the first and second connectors may be magnetically absorptive members, such as magnets or the like.

In addition, in some embodiments, the aforementioned operation portion 131 is used as a first operation portion, and on the basis of this, the dust collecting device further has a second operation portion, and both the first operation portion and the second operation portion can be acted by an external force and are respectively located at two sides of the tub 110. At this time, in addition to releasing the engagement of the free end 1412 of the locking member 141 with the abutting end 1251 by the driving member 132 and the transmission member 133, the opening of the lid 120 can be achieved by directly operating the second operation portion. For example, the locking member 141 may have or be the second operation portion, and the opening of the lid 120 may be performed by operating the second operation portion such that the free end 1412 of the locking member 141 rotates about the rotation fulcrum 1411 to be away from the position abutting against the abutting end 1251. Through this arrangement, the cover 120 has two opening modes, namely, opening by driving the driving member 132 and the transmission member 133 and opening by driving the locking member 141, which can be convenient for a user to select according to the requirement of the actual usage scenario, and the opening mode by driving the locking member 141 can be used as a redundant backup mode of the opening modes by driving the driving member 132 and the transmission member 133, so as to avoid the situation that the cover 120 cannot be opened when the driving member 132 and/or the transmission member 133 fails.

It should be understood that, in other embodiments, the unlocking member 150 is not limited to be disposed on the cover 120, but may be disposed on other components, such as the barrel 110, and when the locking structures 140 are connected to each other, the unlocking member 150 can drive the driving member 132 and disengage the locking structures 140.

In some embodiments, the driving member 132 may be a driving mechanism, such as a motor, a cylinder, etc., and the user may operate the driving member 132 by manipulating the operating portion 131 of the releasing mechanism 130, and may move the cover 120 from the closed position to the open position by using the transmission member 133.

The release mechanism 130 is an air cylinder, and the air cylinder is activated by a user operating the operating portion 131 of the release mechanism 130 to drive the transmission member 133 to move in the second direction, and the transmission member 133 drives the unlocking member 150 to move in the first direction, so as to release the mating connection of the locking structure 140, and the cover 120 may move from the closed position to the open position.

In other embodiments, the driving member 132 may be a manually driven structure, where the driving member 132 has the operation portion 131 for a user to operate, and the user can move the driving member 132 by moving the operation portion 131, and can move the cover 120 from the closed position to the open position through the transmission member 133.

The driving member 132 is a push rod, which may be disposed in the tub 110, and has an operating handle exposed at the operating side 113 as the operating portion 131, and the driving member 132 may be driven to move in the second direction by pulling the operating portion 131, and the unlocking member 150 may be driven to move in the first direction by the transmission member 133, so that the mating connection of the locking structure 140 is released, and the cover 120 may be moved from the closed position to the open position.

In some embodiments, the release mechanism 130 is disposed on the operating side 113 of the tub 110 to prevent the collection from contaminating the release mechanism 130 and affecting the release mechanism 130 when it exits the receiving space 111. For example, when the release mechanism 130 includes a driving member 132 and a transmission member 133, the driving member 132 and the transmission member 133 are disposed on the operation side 113 of the tub 110. Further, this arrangement may also allow the release mechanism 130 or the operating portion 131 of the release mechanism 130 to be conveniently located on the operating side 113 of the other component after the dust collecting device is assembled to the other component. Therefore, the dust collecting device can be used by being mounted on other components, and the problem of contamination of the user and components caused by the collected matter being prevented from escaping to the operation side 113 when the collected matter leaves the accommodating space 111 can be avoided.

In addition, the dust collecting device is easily adhered to the inside of the dust collecting device, for example, to the inner wall of the tub 110, due to its own characteristics or due to the ambient temperature and humidity.

And, a filter assembly 160 may be disposed in the accommodating space 111 of the dust collecting device, and when the dust collecting device is applied, a dust-containing air flow enters the dust collecting device through the air inlet 115 of the dust collecting device, and leaves the dust collecting device through the air outlet of the dust collecting device after passing through the filter assembly 160, and dust and impurities are filtered out by the dust-containing air flow through the filter assembly 160.

Wherein the filter assembly 160 generally comprises an outermost mesh filter having mesh openings disposed therein for filtering out larger particles of dust and debris. Downstream of the mesh filter, a filter structure such as a filter cotton and/or a cyclone cone may be provided to further filter the dusty gas stream, and the collection may also be prone to adhere to the filter assembly 160, particularly the mesh filter. It is to be understood that in other embodiments, the specific structural arrangement of the filter assembly 160 is not limited to the above description.

The sticking of the collection material within the receiving space 111 may result in a risk of clogging of the filter assembly 160 and loss of overall suction, resulting in a reduction in the time of use of the filter assembly 160 and a reduction in the effective storage capacity of the dust collection device, and also in a tendency to grow pathogens.

Accordingly, in some embodiments, in order to facilitate the cleaning of the accommodating space 111 by the user and to avoid contamination of the operation position (e.g., hand, etc.) of the user during the cleaning, a cleaning assembly 170 may be further provided in the accommodating space 111, and the cleaning assembly 170 may be used to clean the accommodating space 111, such as the inner wall of the tub 110 and/or the filter assembly 160 provided in the accommodating space 111.

The cleaning assembly 170 may be a contact type ash removing mechanism, such as a scraping plate, a scraping bar, or the like, or a non-contact type ash removing mechanism, such as a manner of supplying a pressure medium to remove ash. The dust collection device can be cleaned by controlling the dust removal mechanism to move along the second direction, or to move along the circumferential direction of the accommodating space 111 or other directions. The specific structure of the cleaning assembly 170 is not limited in this embodiment, and it is only required to clean the dust collecting device.

In some embodiments, the cleaning assembly 170 includes a scraping member, such as a scraper, which may be provided in one or more pieces, and a first cleaning part provided at a side of the scraper adjacent to the inner wall of the tub 110, for cleaning the inner wall of the tub 110; the scraper is provided with a second cleaning part at a side close to the cleaning assembly 170 for cleaning the cleaning assembly 170, and in particular, may be used for cleaning a mesh cleaner of the cleaning assembly 170. The first cleaning portion and the second cleaning portion may be made of the same material and/or shape, or may be made of different materials and/or shapes, which is not limited in this embodiment. It will be appreciated that in other embodiments, the cleaning assembly 170 may take other configurations.

In order to facilitate the cleaning process of the accommodating space 111, the release mechanism 130 of the dust collecting device is further a linkage release mechanism 130, and the linkage release mechanism 130 is configured to control the cleaning assembly 170 and the cover 120 in a linkage manner, so as to enable the cover 120 to move from the closed position to the open position and enable the cleaning assembly 170 to clean the collected objects in the accommodating space 111.

The operation portion 131 of the interlocking release mechanism 130, that is, the operation portion 131 of the release mechanism 130 is provided on the operation side 113 of the tub 110. Therefore, when the operation portion 131 is operated to operate the linkage release mechanism 130, since the fixed end 122 of the cover 120 is close to the operation side 113 of the tub 110, the collected objects leaving the accommodating space 111 are not easy to drift toward the operation side 113 when the cover 120 is in the open position, and the user located on the operation side 113 and the operation position of the user are not easy to be polluted, so that the user experience when cleaning the dust collecting device can be improved; and the operation part 131 is not easily affected by the collected matter leaving the accommodation space 111, which helps to ensure the cleanliness and effective use of the operation part 131.

The linkage release mechanism 130 may take a variety of different forms to implement a linkage operation for moving the cover 120 from the closed position to the open position and for cleaning the collection in the accommodating space 111 by the cleaning assembly 170, i.e. to control the cover 120 to open and to control the cleaning assembly 170 to perform a cleaning operation.

In some embodiments, the linkage release mechanism 130 includes a drive member 132, a transmission member 133, and an unlocking member 150; wherein, the driving member 132 is connected with the transmission member 133 and can drive the transmission member 133 to move; the transmission member 133 is matched with the unlocking member 150 to drive the unlocking member 150 to move so as to open the locking structure 140, and the transmission member 133 is matched with the cleaning assembly 170 to enable the cleaning assembly 170 to clean the accommodating space 111.

In some examples, the cleaning assembly 170 can be controlled by the linkage release mechanism 130 and rotated within the receiving space 111 to perform a cleaning action, enabling cleaning of the inner walls of the filter assembly and/or the tub 110.

Illustratively, the driving member 133 is threadably engaged with the cleaning assembly 170 and is coupled to the cover 120. When the driving member 133 is driven by the driving member 132 to move, the driving member 132 and the driving member 133 are engaged with each other through threads, so that the cleaning assembly 170 can be synchronously driven to rotate. Specifically, one end of the transmission member 133 may be connected to one end of the opening/closing end 121 of the cover 120, and a mating portion of the transmission member 133 and the cleaning assembly 170 may have a gear structure, so that when the transmission member 133 is driven by the driving member 132 to move in the second direction, the cover 120 may be opened and the cleaning assembly 170 may be rotated in the accommodating space 111 to perform the cleaning operation.

Illustratively, the driving member 133 is engaged with the cleaning assembly 170 by threads, and the driving member 133 is also driven by the driving member 132 to move in the second direction, but unlike the previous illustration, the driving member 133 is not connected to the cover 120 in this illustration. In this example, the dust collecting device includes the unlocking member 150 and the locking structure 140, and the transmission member 133 can cooperate with the unlocking member 150 to move the unlocking member 150 during the movement in the second direction, and apply a force to the locking structure 140 through the unlocking member 150 to release the locking structure 140 from the locking connection, so that the cover 120 can move from the closed position to the open position.

In some examples, the cleaning assembly 170 is controllable by the linkage release mechanism 130 and moves in the second direction to perform a cleaning action. The cleaning member 170 is positioned at an initial position before moving in the second direction, and is positioned at a final position after moving in the second direction, and the initial position is further away from the release port 112 than the final position. When the driving member 133 is driven to move by the driving member 132, the cleaning assembly 170 is driven to move from the initial position to the end position along the second direction, and the cover 120 is driven to move from the closed position to the open position.

Illustratively, the transmission member 133 is connected to the cover 120 and the cleaning assembly 170, and can synchronously move the cover 120 and the cleaning assembly 170 when the transmission member 133 is driven to move by the driving member 132. Specifically, one end of the transmission member 133 may be connected to one end of the cover 120 at the switch end 121 and the other end may be connected to the cleaning unit 170, so that the cover 120 may be opened and the cleaning unit 170 may be moved in the second direction when the transmission member 133 is driven by the driving member 132 to move in the second direction. More specifically, the dust collecting device has at least three states of a first state, a second state and a third state when the interlock release mechanism 130 is operated.

Wherein in a first state, i.e., an initial state, the cover 120 is in the closed position held at the release port 112, the cleaning assembly 170 is in the initial position further than the release port 112.

In the second state, i.e. the intermediate state, the transmission member 133 is driven by the driving member 132 to move in the second direction, so as to drive the cleaning assembly 170 to move in the second direction and perform the cleaning operation, and drive the end of the switch end 121 of the cover 120 to move downward to start to release the mating connection with the locking structure 140. The locking structure 140 may be a magnetic structure or the like.

In a third state, namely, a cleaning completion state, the transmission member 133 is driven by the driving member 132 to move to the second direction in place, and drives the cleaning assembly 170 to the end position, so that the cleaning action is completed; and the transmission member 133 drives the cover 120 to the open position, the locking structure 140 is completely disengaged, the release opening 112 is opened by the cover 120, and the collected objects can leave the accommodating space 111 through the release opening 112.

Illustratively, the driving member 133 is connected to the cleaning assembly 170, and the driving member 133 is also driven by the driving member 132 to move in the second direction, but unlike the previous illustration, the driving member 133 is not connected to the cover 120 in this illustration. In this example, the dust collecting device includes the unlocking member 150 and the locking structure 140, and the transmission member 133 can cooperate with the unlocking member 150 to move the unlocking member 150 in the process of moving in the second direction, and apply a force to the locking structure 140 through the unlocking member 150 so that the locking structure 140 is disengaged, and the cover 120 can be opened.

The side of the cover 120 near the operation side 113 is the fixed end 122, the locking structure 140 is disposed at an end of the opening/closing end 121 of the cover 120 and an end of the barrel 110 corresponding to the opening/closing end 121, and the opening/closing end 121 is any side other than the fixed end 122, i.e., the opening/closing end 121 is far away from the operation side 113 relative to the fixed end 122. Wherein, when the locking structure 140 is in the state of being cooperatively connected, the cover 120 is located at the closed position; when the mating connection state of the locking structure 140 is released, the cover 120 can be moved to the open position.

In further examples, as shown in fig. 1 to 17, the fixed end 122 and the switch end 121 are opposite ends of the cover 120, and a direction in which the fixed end 122 points to the switch end 121 is a first direction; the unlocking member 150 is driven by the release mechanism 130 and moves along the first direction to apply force to the locking structure 140 and release the mating connection of the locking structure. At this time, when the interlock release mechanism 130 is operated, the dust collecting device also has at least three states of a first state, a second state and a third state.

Referring to fig. 1, 4, 7, 10, 13 and 14, in a first state, i.e., an initial state, the cover 120 is in the closed position held at the release port 112, and the cleaning assembly 170 is in the initial position further than the release port 112.

As shown in fig. 2, 5, 8, 11, 15 and 16, in the second state, i.e., in the intermediate state, the transmission member 133 is driven by the driving member 132 to move in the second direction, so as to drive the cleaning assembly 170 to move in the second direction and perform the cleaning operation, and drive the unlocking member 150 to move in the first direction, so that the locking structure 140 gradually starts to be disengaged.

As shown in fig. 3, 6, 9, 12, and 17, in the third state, that is, the cleaning completion state, the transmission member 133 is driven by the driving member 132 to move in the second direction, and drives the cleaning assembly 170 to the end position, so that the cleaning action is completed; and the transmission member 133 drives the unlocking member 150 to a position where the locking structure 140 is completely disengaged, the cover 120 can be opened, so that the collected objects can leave the accommodating space 111 through the release opening 112. If the release opening 112 and the cover 120 are disposed downward, i.e., disposed at the bottom of the tub 110, the cover 120 can rotate to the open position by gravity, so that the release opening 112 is opened. It will be appreciated that in other embodiments, the release opening 112 may not be located in a downward position, and the release mechanism 130 may further include a mechanism for driving the cover 120 to open or otherwise open the cover 120 when the locking structures 140 have been disengaged from each other.

It should be understood that the unlocking member 150 is not limited to be disposed on the cover 120, but may be disposed on other components, such as the tub 110, and when the locking structures 140 are connected to each other, the unlocking member 150 may be configured to drive the linkage release mechanism 130 and disengage the locking structures 140 from each other.

It should be understood that the transmission member 133 may be one component or may be a plurality of components, for example, a plurality of components that cooperate with each other to achieve a transmission effect, for example, the transmission member 133 may be provided for the cover 120 and the cleaning assembly 170, respectively, so long as the linkage release mechanism 130 is capable of achieving linkage control, so that the cover 120 can move from the closed position to the open position, and the cleaning assembly 170 can clean the accommodating space 111.

In some embodiments, based on the example in which the transmission member 133 moves along the second direction, in order to make the movement process of the transmission member 133 when driving the cleaning assembly 170 to move more stable, the cleaning assembly 170 is prevented from deflecting to one side when driving the cleaning assembly 170 to move, thereby causing damage such as scraping. The transmission member 133 includes a connection section and a base section 1332 opposite to the connection section, the connection section is used for being connected with the cleaning assembly 170, and an elastic member disposed along the second direction is connected between the base section 1332 and the connection section.

Illustratively, as shown in fig. 7 and 18, the connection section includes symmetrically arranged connection sections 1331, the connection sections 1331 are all connected to the cleaning assembly 170, tension springs are all arranged between the connection sections 1331 and the base section 1332 to serve as the elastic members, and the driving members 132 are connected to the base section 1332.

In some embodiments, to protect the interlock release mechanism 130, the interlock release mechanism 130 is protected from external influences due to exposure to the outside. The dust collecting device may have a receiving chamber having a first guide opening communicating to the outside of the operation side 113 of the tub 110 and a second guide opening communicating to the receiving space 111.
