Description

Technical Field

[0001] The present disclosure relates to the field of cleaning equipment, and in particular, to a dust cup and a cleaning equipment having the same. Background Art

[0002] With the continuous improvement of living standards, people's requirements for living and working environments are getting higher and higher. In order to ensure that the environment has a good cleanliness, cleaning equipment has emerged to clean various places or objects. The use of cleaning equipment not only reduces the labor cost of cleaning work, but also improves the efficiency of cleaning work.

[0003] A cleaning device, such as a horizontal vacuum cleaner, includes a body and a dust cup, and the dust cup is placed on the body. The dust cup includes a cup body and a cup cover, and the cup body is provided with a dust holding chamber and a dust discharge port. The cup cover can be pivotally mounted on the cup body to open or close the dust discharge port by pivoting. During operation, a suction source in the body generates negative pressure to suck in air and dust, and then collects the dust in the dust cup to achieve a cleaning purpose. After a lot of dust accumulates in the dust cup, the user can open the dust discharge port to empty the dust in the dust cup.

[0004] The dust cup may further include a locking mechanism, which has a locked state and an unlocked state. In the locked state, the locking mechanism keeps the cup cover and the cup body locked to prevent the dust outlet from being accidentally opened. In the unlocked state, the locking mechanism releases the lock of the cup cover and the cup body to allow the cup cover to open the dust outlet by pivoting. When opening the cup cover, the user may perform improper operations, such as trying to forcibly pivot the cup cover to open the dust outlet when the locking mechanism is in the locked state, which may cause damage to the dust cup. Utility Model Content

[0005] In view of this, the present disclosure provides a dust cup of a cleaning device and a cleaning device, aiming to reduce the possibility of the locking structure of the cup cover being damaged.

[0006] On the one hand, the present disclosure provides a dust cup of a cleaning device, which includes a cup body, a cup cover and a locking mechanism. The cup body defines a dust holding chamber for holding dust and a dust outlet connecting the dust holding chamber and the outside. The cup cover can be pivotally mounted on the cup body to open or close the dust outlet by pivoting. The locking mechanism is used to keep the cup cover and the cup body locked in a locked state, and release the lock of the cup cover and the cup body in an unlocked state. The locking mechanism includes a first moving member and a second moving member. The first moving member includes a first interference portion, and is connected to the cup cover or formed integrally with the cup cover to drive the cup cover to move or be driven by the cup cover to move. The second moving member includes a second interference portion, and the second interference portion is configured to interfere with the first interference portion in a locked state to keep the cup cover and the cup body locked, and is configured to disengage the interference with the first interference portion in an unlocked state to release the lock of the cup cover and the cup body. The second moving member can be driven to move the second interference part along the first direction to disengage the interference with the first interference part, and the first moving member can be driven to move the first interference part along the second direction to disengage the interference with the second interference part, and the first direction and the second direction are substantially opposite.

[0007] On the one hand, when it is necessary to unlock the lock between the cup lid and the cup body, the operator can drive the second moving member to move the second interference part in the first direction to disengage the interference between the second interference part and the first interference part, so as to release the lock between the cup lid and the cup body and allow the cup lid to be opened. On the other hand, when the operator forcibly pivots the cup lid to open the dust outlet, the first moving member connected to the cup lid is driven to move the first interference part in the second direction to disengage the interference between the first interference part and the second interference part, thereby allowing the cup lid to be smoothly opened. In this way, the locking mechanism with the above-mentioned structure will have a protection mechanism. The operator can release the lock between the cup lid and the cup body by unlocking the locking mechanism, and then open the dust outlet. The operator can also forcibly open the dust outlet by pivoting the cup lid without damaging the dust cup. It can be seen that the dust cup provided by the present invention is not easily damaged by improper operation.

[0008] In a possible implementation, the first moving member includes a first pivoting portion and a connecting portion, the connecting portion and the first interfering portion are disposed on opposite sides of the first pivoting portion, and the connecting portion is integrally connected to the cup cover. Under the force applied to the cup cover, the first moving member pivots around the first pivoting portion, so that the first interfering portion moves in the second direction to disengage from the interfering portion.

[0009] In this implementation, the first pivoting portion is provided with a connecting portion and a first interfering portion on both sides, and the connecting portion is integrally connected to the cup cover. In this way, when the operator pulls up the cup cover, the connecting portion rotates with the cup cover, and the first interfering portion is driven to move by the first pivoting portion to disengage the interfering portion between the first interfering portion and the second interfering portion, so that the cup cover can be opened smoothly.

[0010] In a possible implementation, the locking mechanism further includes a first elastic member connected to the first moving member. The first elastic member is compressed when the first abutting portion abuts against the second abutting portion and is in a locked state, and is released when the first abutting portion disengages from abutting against the second abutting portion, thereby driving the first moving member to move around the first pivoting portion, so as to drive the cup cover to open the dust outlet through the connecting portion.

[0011] The first elastic member in the locked state is compressed due to the interference between the first and second interference parts, thereby storing elastic potential energy. When the first interference part disengages from the interference with the second interference part, the potential energy of the first elastic member is released, thereby driving the first interference part to move around the first pivot part, and driving the cup cover to open the dust outlet through the connecting part. In the operation of opening the cup cover, compared with the operator fully providing the force to drive the first interference part, the implementation method provided by the present disclosure can utilize a part of the elastic force of the first elastic member, thereby making the operation easier.

[0012] In a possible implementation, the second moving member further includes an operating portion, and the second interference portion moves along the first direction under the force applied to the operating portion to break away from the interference with the first interference portion.

[0013] In this way, the operator only needs to apply a force on the operating part to conveniently switch the locking mechanism from a locked state to an unlocked state.

[0014] In one possible implementation, the dust cup of the cleaning device also includes a handle, which is arranged on the outside of the dust cup and extends generally between the top and the bottom of the dust cup, and the operating part is arranged on one end of the handle close to the top of the dust cup.

[0015] In this way, the operator can operate the operating part located on the top of the handle with the thumb while holding the handle to complete the action of opening the cup cover, so that the operator can open the cup cover more easily when holding the dust cup.

[0016] In a possible implementation, the second moving member further includes a second pivoting portion, and the operating portion and the second interfering portion are located on opposite sides of the second pivoting portion. The second moving member pivots around the second pivoting portion to move the second interfering portion along the first direction to disengage the interfering portion from the first interfering portion. In the locked state, the angle between the extrusion force borne by the contact portion of the first interfering portion contacting the second interfering portion and the first direction is less than 90 degrees.

[0017] Since the angle between the extrusion force borne by the contact portion of the first contact part contacting the second contact part and the first direction is less than 90 degrees, the component of the extrusion force in the first direction will be greater than 0 at the contact point between the first contact part and the second contact part. In this way, as the first moving part is driven to move the first contact part in the second direction, the second contact part will be driven to move in the first direction under the extrusion force from the first moving part, so that the first contact part and the second contact part are separated and the cup cover is released.

[0018] In a possible implementation manner, the contact surfaces of the first abutting portion and the second abutting portion that contact each other are both smooth curved surfaces.

[0019] Since the contact surface is a smooth curved surface, the contact between the first abutting portion and the second abutting portion will be a line contact rather than a point contact, which is beneficial to avoid the contact surface from being crushed, thereby helping to increase the service life of the dust cup.

[0020] In a possible implementation, the second moving member further includes a third resisting portion, and the handle further includes a fourth resisting portion. In a locked state, the third resisting portion resists the fourth resisting portion to prevent the second resisting portion from moving along the second direction.

[0021] In one possible implementation, a receiving space is provided in the handle, a concave seat is provided at the bottom of the receiving space, the second movable part also includes a lower convex part located in the receiving space, and the dust cup also includes a second elastic part, the elastic upper end is sleeved on the lower convex part and its lower end extends into the seat.

[0022] Like this, under normal conditions, the second elastic member can keep the second moving member in the position that conflicts with the first moving member, so that the locking mechanism is kept in the locked state. When the second moving member or the first moving member is released after unlocking, the second elastic member can drive the second moving member to reset.

[0023] On the other hand, the present disclosure also provides a cleaning device, including the dust cup mentioned above. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present disclosure.

[0034] The present disclosure provides a cleaning device 100. For example, the cleaning device 100 provided by the present disclosure may be a vacuum cleaner. In particular, it may be a horizontal vacuum cleaner. Of course, the cleaning device 100 provided by the present disclosure is not limited to a vacuum cleaner. Generally speaking, the cleaning device 100 provided by the present disclosure may be any type of cleaning device, as long as it cleans the surface to be cleaned or the object to be cleaned by sucking airflow.

[0035] refer to Figure 1 , the cleaning device 100 may include a body 200 and a dust cup 300. Under normal circumstances, the dust cup 300 may be placed on the body 200. A suction source (not shown) may be provided in the body 200, for example, the suction source may be a fan. When the cleaning device 100 is running, the suction source will generate negative pressure, suck in air and dust by suction, so as to collect the dust in the dust cup 300, thereby achieving the purpose of cleaning. After a lot of dust accumulates in the dust cup 300, the operator can remove the dust cup 300 from the body 200, and then empty the dust in the dust cup 300.

[0036] refer to Figure 2 and Figure 3The dust cup 300 may include a cup body 10, a cup cover 20 and a locking mechanism 30. The cup body 10 defines a dust holding chamber 11 therein, and defines a dust dumping port 12 located at the top of the dust holding chamber 11. The dust holding chamber 11 is configured to contain dust debris, and the dust holding chamber 11 is connected to the outside through the dust dumping port 12. The cup cover 20 is pivotally mounted on the cup body 10 to open or close the dust dumping port 12 by pivoting. The locking mechanism 30 has a locked state and an unlocked state. In the locked state, the locking mechanism 30 keeps the cup cover 20 and the cup body 10 locked, that is, keeps the cup cover 20 closed to the dust dumping port 12 to prevent the dust dumping port 12 from being accidentally opened. In the unlocked state, the locking mechanism 30 releases the lock of the cup cover 20 and the cup body 10 to allow the cup cover 20 to open the dust dumping port 12 by pivoting.

[0037] Normally, the operator can operate the locking mechanism 30 to switch the locking mechanism 30 from a locked state to a released state, and then open the dust outlet 12. However, the operator may attempt to forcibly pivot the cup cover 20 to open the dust outlet 12 through improper operation when the locking mechanism 30 is in a locked state. In order to prevent the dust cup 100 from being damaged due to improper operation, the locking mechanism 30 is constructed to have a protection mechanism. Below, the construction of the locking mechanism 30 is illustrated by example.

[0038] Combination Figure 4A and Figure 4B , the locking mechanism 30 may include a first moving member 31 and a second moving member 32. The first moving member 31 includes a first abutment portion 313, and is connected to the cup cover 20 or formed integrally with the cup cover 20 to drive the cup cover 20 to move or be driven by the cup cover 20 to move. In one example, the first moving member 31 may be integrally connected to the cup cover 20, that is, the first moving member 31 may be integrally formed with the cup cover 20. In one example, further, the cup cover 20 may be composed of a first cup cover portion 21 and a second cup cover portion 20 assembled together, and the first moving member 31 may be integrally connected to the cup cover 20.

[0039] It is understood that, in some examples, the first moving member 31 and the cup cover 20 can be two independent components, and the first moving member 31 can be detachably fixed to the cup cover 20. It is also understood that, in some examples, the cup cover 20 can be an integrally formed whole component; or, in some examples, the cup cover 20 can be composed of more independent components assembled together.

[0040] The second moving member 32 includes a second abutment portion 321. When the locking mechanism 30 is in the locked state, Figure 4A As shown, the second abutment portion 321 abuts against the first abutment portion 313, so that the cup cover 20 and the cup body 10 remain locked. As the locking mechanism 30 is switched to the unlocked state, the combination Figure 4A and Figure 4B As shown, the second moving member 32 is driven to move the second interference portion 321 along the first direction S1, disengaging from the interference with the first interference portion 313, so as to release the lock of the cup cover 20 and the cup body 10. In addition, the first moving member 31 can be driven to move the first interference portion 313 along the second direction S2 substantially opposite to the first direction S1, so as to disengage from the interference with the second interference portion 321.

[0041] It is understood that the first direction S1 and the second direction S2 may be substantially opposite to each other, but not completely opposite to each other. That is, the first direction S1 and the second direction S2 may not be collinear. Figure 4A In the placement posture shown, the first direction S1 is generally directed to the upper left in the figure, and the second direction S2 is generally directed to the lower right in the figure. More specifically, the first direction S1 can be substantially perpendicular to the line from the second abutting portion 321 to the second pivoting portion 323, and the second direction S2 can be substantially perpendicular to the line from the first abutting portion 313 to the first pivoting portion 311. The specific details of the first pivoting portion 311 and the second pivoting portion 323 will be given below and will not be repeated here.

[0042] On the one hand, when the lock between the cup cover 20 and the cup body 10 needs to be unlocked, the operator can drive the second moving member 32 to move the second conflicting portion 321 along the first direction S1, so that it disengages from the conflict with the first conflicting portion 313, so as to release the lock between the cup cover 20 and the cup body 10, and allow the cup cover 20 to be opened. On the other hand, when the operator forcibly pivots the cup cover 20 to open the dust outlet 12, the first moving member 31 connected to the cup cover 20 is driven to move the first conflicting portion 313 along the second direction S2, disengaging from the conflict with the second conflicting portion 321, thereby allowing the cup cover 20 to be smoothly opened. In this way, the locking mechanism 30 of the above structure will have a protection mechanism. The operator can release the lock between the cup cover 20 and the cup body 10 by unlocking the locking mechanism 30, and then open the dust outlet 12. The operator can also forcibly open the dust outlet 12 by pivoting the cup cover 20 without damaging the dust cup 300. It can be seen that the dust cup 300 provided by the present invention is not easily damaged due to improper operation.

[0043] Continue to refer Figure 4A and Figure 4B The first moving member 31 may include a first pivoting portion 311 and a connecting portion 312, wherein the connecting portion 312 and the first abutting portion 313 are disposed on opposite sides of the first pivoting portion 311. The connecting portion 312 may be integrally connected to the cup cover 20, or may be detachably connected to the cup cover 20. Figure 4A As shown in FIG. 3 , when the locking mechanism 30 is in the locked state, the first abutting portion 313 abuts against the second abutting portion 321 . Figure 4A and Figure 4BThe second moving member 32 can be driven to move the second abutting portion 321 along the first direction S1, disengaging from the abutting portion 313, so as to release the locking of the cup cover 20 and the cup body 10. Figure 4A and Figure 4B Under the force applied to the cup cover 20, the first moving member 31 pivots around the first pivoting portion 311, so that the first interference portion 313 moves along the second direction S2, disengaging from the interference with the second interference portion 321 to release the lock of the cup cover 20 and the cup body 10.

[0044] In this implementation, the first pivoting portion 311 is flanked by a connecting portion 312 and a first abutting portion 313, and the connecting portion 312 is integrally connected to the cup cover 20. In this way, after the operator lifts the cup cover 20, the connecting portion 312 rotates with the cup cover 20, and the first abutting portion 313 is driven to move through the first pivoting portion 311, so as to disengage the abutment between the first abutting portion 313 and the second abutting portion 321, so that the cup cover 20 can be opened smoothly.

[0045] refer to Figure 3 , Figure 4A and Figure 4B The locking mechanism 30 may further include a first elastic member 33, and the first elastic member 33 may be connected to the first moving member 31. For example, the first elastic member 33 may be implemented as a torsion spring. When the locking mechanism 30 is in a locked state, that is, when the first interference portion 313 is in conflict with the second interference portion 321, the first elastic member 33 is compressed. When the first interference portion 313 is disengaged from the conflict with the second interference portion 321, the first elastic member 33 is released to drive the first moving member 31 to move around the first pivot portion 311, and then drive the cup cover 20 to open the dust outlet 12 through the connecting portion 312.

[0046] The first elastic member 33 in the locked state is compressed due to the interference between the first interference portion 313 and the second interference portion 321, thereby storing elastic potential energy. When the first interference portion 313 is disengaged from the interference with the second interference portion 321, the potential energy of the first elastic member 33 is released, thereby driving the first interference portion 313 to move around the first pivot portion 311, and driving the cup cover 20 to open the dust outlet 12 through the connecting portion 312. In the operation of opening the cup cover 20, compared to the operator fully providing the force to drive the first interference portion 313, the implementation method provided by the present disclosure can utilize a part of the elastic force of the first elastic member 33, thereby making the operation easier.

[0047] refer to Figure 4A and Figure 4BThe second moving member 32 may include an operating portion 322, and the second moving member 32 may be in contact with the first contact portion 313 through the second contact portion 321. The operating portion 322 may be configured to receive an operation by an operator, so that the second contact portion 321 moves along the first direction S1 under the force applied to the operating portion 322 to break away from the contact with the first contact portion 313. In this way, the operator only needs to apply a force on the operating portion 322 to conveniently switch the locking mechanism 30 from the locked state to the unlocked state.

[0048] Back to Figure 2 The dust cup 100 may further include a handle 40, which may be disposed on the outside of the dust cup 100 and generally extend between the top and the bottom of the dust cup 100, and the operating portion 322 may be disposed on the handle 40 at one end close to the top of the dust cup 100. In this way, while holding the handle 40, the operator can also operate the operating portion 322 at the top of the handle 40 with the thumb to complete the action of opening the cup cover 20, so that the operator can easily open the cup cover 20 while holding the dust cup 100.

[0049] Again, refer to 4A and Figure 4B The second moving member 32 may further include a second pivoting portion 323, and the operating portion 322 and the second contacting portion 321 may be located at opposite sides of the second pivoting portion 323. The second moving member 32 may pivot around the second pivoting portion 323 to move the second contacting portion 321 along the first direction S1 to disengage the contacting portion 321 from the first contacting portion 313. Figure 5 In the locked state, the angle between the extrusion force F borne by the contact portion of the first contact portion 313 contacting the second contact portion 321 and the first direction S1 may be less than 90 degrees.

[0050] Since the angle between the extrusion force F borne by the contact portion of the first abutting portion 313 contacting the second abutting portion 321 and the first direction S1 is less than 90 degrees, the component force of the extrusion force F in the first direction S1 will be greater than 0 at the contact point A between the first abutting portion 313 and the second abutting portion 321. In this way, as the first moving member 31 is driven to move the first abutting portion 313 along the second direction S2, as long as the external force applied to the cup cover 20 is large enough, the second abutting portion 321 will be driven to move along the first direction S1 under the action of the extrusion force F from the first moving member 31, so that the first abutting portion 313 and the second abutting portion 321 are separated, and the cup cover 20 is released.

[0051] Continue to refer Figure 4A and Figure 4BThe contact surfaces of the first and second abutting portions 313 and 321 can be smooth curved surfaces. Since the contact surfaces are smooth curved surfaces, the contact between the first and second abutting portions 313 and 321 is line contact rather than point contact, which helps to avoid the contact surfaces from being crushed, thereby helping to increase the service life of the dust cup 100.

[0052] refer to Figure 4A , the second moving member 32 may further include a third abutment portion 324, and the handle 40 may further include a fourth abutment portion 42. When the locking mechanism 30 is in the locked state, as shown in FIG. Figure 4A As shown, the third resisting portion 324 resists against the fourth resisting portion 42 to prevent the second resisting portion 321 from moving along the second direction S2 .

[0053] Continue to refer Figure 4A , a receiving space 41 may be provided in the handle 40, a concave seat 411 may be provided at the bottom of the receiving space 41, the second moving member 32 also includes a lower convex portion 325 that can be located in the receiving space 41, and the dust cup 100 may also include a second elastic member 34. The upper end of the second elastic member 34 may be sleeved on the lower convex portion 325, and the lower end thereof may extend into the seat 411. Under normal conditions, the second elastic member 34 can keep the second moving member 32 in a position that conflicts with the first moving member 31, so as to keep the locking mechanism 30 in a locked state. When the second moving member 32 or the first moving member 31 is released after being unlocked, the second elastic member 34 can drive the second moving member 32 to reset.

[0054] Back to Figure 3 The handle 40 may include a first handle portion 41 and a second handle portion 42, which together define a receiving space 41. The first handle portion 41 may be integrally or detachably connected to the cup body 10, and the second handle portion 42 may be mounted on the first handle portion 41.

[0055] It should be understood that the term "including" and its variations used in the present disclosure are open inclusions, i.e., "including but not limited to". The term "according to" means "at least in part according to". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least another embodiment".

[0056] It should be understood that although the terms "first" or "second" etc. may be used in the present disclosure to describe various elements (such as a first moving part and a second moving part), these elements are not defined by these terms, and these terms are only used to distinguish one element from another.

[0057] The protection scope of the present disclosure is not limited to the above-mentioned embodiments. Any changes or substitutions that can be conceived by any person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
