[0030] The following describes the technical solutions in the embodiments of the present invention in a clear and complete manner in combination with the drawings in the embodiments of the present invention, but it is clear that the described embodiments are only a part of the embodiments of the present invention, and do not represent all the embodiments. Based on the embodiments of the present invention, those skilled in the art will not make any inventive efforts, and all other examples obtained fall within the scope of protection of the present invention.
[0031] Embodiment 1 An embodiment of the present disclosure provides a cleaning system, and as shown in FIGS. 1 to 7, the cleaning system includes a base station 1 and a cleaning device 2. The cleaning device 2 can discharge dust to the base station 1, and when the cleaning device 2 discharges the dust to the base station 1, the base station 1 removes foreign objects within the cleaning device 2.
[0032] In one embodiment, the base station 1 includes a dust collecting member 10 and a suction mechanism 11. The dust collecting member 10 has a first dust collecting chamber 10a and a dust collecting port 10b communicating with the first dust collecting chamber 10a. The suction mechanism 11 can generate suction force.
[0033] In one embodiment, the cleaning device 2 includes a cleaning body 20, a dust cup 21, a locking unit 4, and a dust cup cover 22. The dust cup 21 is attached to the cleaning body 20, and the dust cup cover 22 is attached to the dust cup 21. The dust cup 21 has a first storage chamber 21a and a dust outlet 21b communicating with the first storage chamber 21a, and the first storage chamber 21a can collect foreign matter. The locking unit 4 is provided on the cleaning body 20, and has an unlocked state and a locked state. When the locking unit 4 is in the unlocked state, the dust cup cover 22 can open the dust outlet 21b, and when the locking unit 4 is in the locked state, the locking unit 4 can lock the dust cup cover 22 with the dust outlet closed.
[0034] In this embodiment, the cleaning device 2 is provided with a locking unit 4 connected to the cleaning body 20. When the locking unit 4 is in a locked state, it can lock the dust cup cover 22 with the dust outlet 21b closed to prevent dust and foreign objects in the dust cup 21 from escaping through the dust outlet 21b. The embodiment of the present disclosure solves the problem of dust and foreign objects leaking from the dust cup 21. The locking unit 4 is also provided on the cleaning body 20. The locking unit 4 is shielded by the cleaning body 20 to prevent direct exposure to the outside. The thickness of the dust cup 21 is thinner than that of the cleaning body 20, and the maximum bearing force that the cleaning body 20 can withstand is greater than that of the dust cup 21. Therefore, by providing the locking unit 4 on the cleaning body 20, damage to components of the cleaning system due to long-term use of the locking unit 4 can be avoided. The shape of the dust cup 21 does not need to be adapted to the locking unit 4, but can be determined according to actual needs.
[0035] In one embodiment, the cleaning body 20 further includes a housing, a blower unit, a brush, a battery, and a handle. The dust cup 21, lock unit 4, dust cup cover 22, blower unit, brush, battery, and handle are all mounted in the housing. The battery is electrically connected to the blower unit, which generates suction to draw external dust and foreign matter through the brush into the housing, where it is collected in the dust cup 21. The handle allows a user to easily grip the cleaning body and move it.
[0036] In one embodiment, the cleaning body 20 and the dust cup 21 are manufactured separately, and then the cleaning body 20 and the dust cup 21 are manufactured separately and then attached together.
[0037] In one embodiment, the housing and dust cup 21 are manufactured separately and then attached together.
[0038] In one embodiment, when the cleaning device 2 discharges dust to the base station 1 and projects along the dust discharge direction 1c, the projected area of the dust discharge outlet 21b is at least partially located within the projected area of the dust collection outlet 10b, the dust cup cover 22 is in a position to open the dust discharge outlet 21b so as to connect the first storage chamber 21a and the first dust collection chamber 10a, and the dust discharge direction 1c is the direction in which dust is discharged from the dust discharge outlet 21b.
[0039] In this embodiment, at least a portion of the projected area of the dust discharge port 21b is located within the projected area of the dust collection port 10b, thereby reducing dust from flying up when the dust is discharged and improving dust discharge efficiency.
[0040] In one embodiment, as shown in FIG. 4, the base station 1 further includes an unlocking member 12 provided on the dust collecting member 10, and when the cleaning device 2 discharges dust to the base station 1, the unlocking member 12 abuts against the lock unit 4 to unlock the lock unit 4.
[0041] In this embodiment, when the cleaning device 2 discharges dust to the base station 1, the unlocking member 12 abuts against the lock unit 4 to unlock the lock unit 4. The unlocking method of the embodiment of the present disclosure is simple and does not require a complex unlocking device.
[0042] 3, a drive surface 41b is formed at one end of the drive member 41 facing the drive side, and the drive surface 41b is inclined from top to bottom along a predetermined direction 1a, with the one end of the drive surface 41b facing the drive side being higher than the other end. The predetermined direction 1a is disposed so as to intersect with the suction direction of the cleaning body 20. The drive member 41 is movable along the predetermined direction 1a relative to the locking member 42, and when the drive member 41 moves from the drive side to the other side, the locking unit 42 switches from a locked state to an unlocked state.
[0043] In this embodiment, the cleaning device 2 moves from above the base station 1 to the base station 1 from top to bottom, and the drive surface 41b can abut against the base station 1, and the base station 1 abuts against the drive surface 41b, thereby moving the drive member 41 from the drive side to the other side so that the lock unit 4 switches from the locked state to the unlocked state.
[0044] In one embodiment, the unlocking member 12 abuts against the drive surface 41b to unlock the lock unit 4.
[0045] It can be understood that when the cleaning device 2 moves from the side of the base station 1 to the drive side along the predetermined direction 1a towards the base station 1, the unlocking member 12 abuts against the drive member 41 so that the drive member 41 displaces along the predetermined direction 1a and unlocks the lock unit 4.
[0046] In one embodiment, as shown in Figures 1 and 6, the first dust collection chamber 10a has a second storage chamber 10c for storing the dust cup cover 22, and when the dust cup cover 22 closes the dust discharge port 21b, the dimension of the dust cup cover 22 along the suction direction of the cleaning body 20 is a first dimension 22a, and the dimension of the second storage chamber 10c along the dust discharge direction 1c is a second dimension 10e, which is larger than the first dimension 22a.
[0047] In this embodiment, when the dust cup cover 22 is in a state in which it opens the dust discharge port 21b, the dust cup cover 22 is positioned within the second storage chamber 10c, and since the first dimension 22a of the dust cup cover 22 is smaller than the second dimension 10e of the second storage chamber 10c, the opening degree of the dust cup cover 22 is secured large, and foreign matter located within the first storage chamber 21a is not blocked by the dust cup cover 22, thereby increasing the efficiency with which the suction mechanism 11 suctions foreign matter within the first storage chamber 21a.
[0048] In one embodiment, the first dust collecting chamber 10a further includes a third storage chamber 10f communicating with the second storage chamber 10c, and the third storage chamber 10f is located between the second storage chamber 10c and the suction mechanism 11.
[0049] 6, the first storage chamber 21a is formed in the dust cup 21, the second storage chamber 10c is formed in the dust collecting member 10, and the first storage chamber 21a is located upstream of the second storage chamber 10c in the suction direction 1c. When the cleaning device 2 discharges dust to the base station 1, the dust cup cover 22 opens the dust discharge port 21b, and the dust cup cover 22 enters the second storage chamber 10c, and the dust is discharged from the first storage chamber 21a to the second storage chamber 10c and finally falls into the third storage chamber 10f.
[0050] In one embodiment, as shown in FIG. 4, the base station 1 further includes a filter 10d provided on the dust collecting member 10, the filter 10d being located on the side of the first dust collecting chamber 10a facing the suction mechanism 11, and the filter 10d is used to prevent dust from entering the suction mechanism 11 from the first dust collecting chamber 10a.
[0051] In one embodiment, the dust outlet 21b is formed in the side wall of the dust cup 21, as shown in FIG.
[0052] In this embodiment, the dust discharge port 21b is formed on the side wall of the dust cup 21, which makes it easier for the cleaning device 2 to dock with the base station 1 when the cleaning device 2 needs to discharge dust to the base station 1, and makes operation more convenient.
[0053] In one embodiment, as shown in FIGS. 1 and 3, the cleaning body 20 has a mounting chamber 20a, the dust cup 21 is located in the mounting chamber 20a, the locking unit 4 is located below the dust cup 21, and the cleaning body 20 is partially supported below the dust cup 21.
[0054] In this embodiment, the locking unit 4 is located below the dust cup 21, and can be switched between a locked state and an unlocked state by moving the locking unit 4 in the vertical direction 1b. The locking unit 4 is located below the dust cup 21 to lock the dust cup cover 22, which reduces the installation gap caused by torsional wear of the dust cup cover 22 and ensures that the dust cup cover 22 can stably close the dust outlet 21b even when used for a long time.
[0055] It should be noted that the embodiment of the present disclosure is not limited to the locking unit 4 being located below the dust cup 21 to lock the dust cup cover 22. In one embodiment, the locking unit 4 is located on the side of the dust cup 21.
[0056] The suction direction of the cleaning body 20 means the direction in which dust and foreign matter enter the dust cup 21 from the outside while the cleaning device 2 is sucking up the dust and foreign matter.
[0057] In one embodiment, as shown in FIG. 2, the dust cup cover 22 comprises a main body 220 and a folded edge 221 connected to each other, the folded edge 221 is located at the lower end of the main body 220, an escape groove 20b is formed in the cleaning body 20, when the dust cup cover 22 closes the dust discharge port 21b, the folded edge 221 is located in the escape groove 20b, and the locking unit 4 locks the folded edge 221 in the locked state, so that the main body 220 keeps the dust discharge port 21b closed.
[0058] In this embodiment, the dust cup cover 22 includes a main body 220 and a folded edge 221 connected to each other. The folded edge 221 can limit the main body 220 so that the dust cup cover 22 can switch from opening the dust outlet 21b to closing the dust outlet 21b and engage with the dust cup 21. The folded edge 221 is located at the bottom end of the main body 220. When the dust cup cover 22 closes the dust outlet 21b, the folded edge 221 is positioned within the relief groove 20b formed in the cleaning body 20, thereby extending the service life of the cleaning body 20. If the folded edge 221 were positioned at the side edge or other position of the main body 220, it would come into contact with the side wall of the cleaning body 20, which could cause damage or deformation to the side wall of the cleaning body 20 after prolonged use. However, the embodiment of the present disclosure can reduce damage to the cleaning body 20 caused by the folded edge 221.
[0059] In one embodiment, as shown in FIG. 3, the body 220 and folded edge 221 are integrally molded.
[0060] In one embodiment, as shown in FIG. 3, a positioning hole 221a is formed in the folded edge 221, and when the lock unit 4 is in the locked state, a part of the lock unit 4 is located in the positioning hole 221a.
[0061] In this embodiment, a positioning hole 221a is formed in the folded edge 221, and when the locking unit 4 is in the locked state, a part of the locking unit 4 is located within the positioning hole 221a. The locking unit 4 and the positioning hole 221a engage with each other and limit each other, thereby making the locking of the locking unit 4 to the dust cup cover 22 more secure.
[0062] It should be understood that the embodiment of the present disclosure is not limited to the positioning hole 221a formed in the folded edge 221, and a portion of the locking unit 4 being located within the positioning hole 221a when the locking unit 4 is in the locked state. In one embodiment, the locking unit 4 abuts against the folded edge 221, and the dust cup cover 22 is locked by the frictional force between the locking unit 4 and the folded edge 221.
[0063] 2 , the locking unit 4 includes an elastic member 40, a driving member 41, and a locking member 42, with one end of the elastic member 40 attached to the cleaning body 20 and the other end attached to the locking member 42. The locking member 42 can approach the dust cup cover 22 to lock the dust cup cover 22 with the dust discharge opening 21b closed, and can move away from the dust cup cover 22 so that the suction mechanism 11 can apply negative pressure to the dust cup cover 22 to open the dust discharge opening 21b. The driving member 41 is used to move the locking member 42 toward or away from the dust cup cover 22.
[0064] In this embodiment, the driving member 41 can move the locking member 42 toward or away from the dust cup cover 22. When the driving member 41 moves the locking member 42 toward the dust cup cover 22, the locking unit 4 switches from an unlocked state to a locked state, and the locking member 42 can lock the dust cup cover 22 so that the dust discharge port 21b remains closed. When the driving member 41 moves the locking member 42 away from the dust cup cover 22, the locking unit 4 switches from the locked state to the unlocked state, and the locking member 42 can release the dust cup cover 22 so that the suction mechanism 11 opens the dust cup cover 22. Furthermore, using the elastic member 40 to press the locking member 42 makes the locking and unlocking means simple and inexpensive.
[0065] In one embodiment, as shown in FIG. 1, when the dust cup cover 22 closes the dust outlet 21b, a portion of the locking member 42 is positioned within the positioning hole 221a.
[0066] In one embodiment, as shown in FIG. 3, a guide groove 20c is formed in the cleaning body 20, a portion of the locking member 42 is positioned within the guide groove 20c, and the guide groove 20c extends along the direction in which the locking member 42 and the elastic member 40 are aligned.
[0067] In this embodiment, a portion of the locking member 42 is positioned within the guide groove 20c, which reduces disturbances to the locking member 42 other than the direction in which the locking member 42 and the elastic member 40 are aligned, making the movement of the locking member 42 more stable. The guide groove 20c also limits the locking member 42, and when the locking member 42 locks the dust cup cover 22 so that the dust discharge port 21b remains closed, the guide groove 20c restricts the displacement of the locking member 42 along the predetermined direction 1a, thereby enhancing the cocking effect of the locking unit 44 on the dust cup cover 22.
[0068] 3 and 5, the locking member 42 is formed with a first abutment surface 42a, which slopes from top to bottom in a predetermined direction 1a, with one end of the first abutment surface 42a facing the drive side being lower than the other end. The predetermined direction 1a is disposed so as to intersect with the suction direction of the cleaning body 20. The drive member 41 is movable relative to the locking member 42 in the predetermined direction 1a, and when the drive member 41 moves from the drive side to the other side, the locking unit 41 switches from the locked state to the unlocked state. The drive member 41 is formed with a second abutment surface 41a that abuts against the first abutment surface 42a, and the shape of the second abutment surface 41a matches the shape of the first abutment surface 42a.
[0069] In this embodiment, the first abutment surface 42a is inclined from top to bottom in the predetermined direction 1a, one end of the first abutment surface 42a facing the drive side is lower than the other end, and a second abutment surface 41a that abuts against the first abutment surface 42a is formed on the drive member 41.As a result, when a force is applied to the drive member 41 from the drive side in the predetermined direction 1a, the first abutment surface 42a and the second abutment surface 41a slide relative to each other, and the lock unit 4 switches from a locked state to an unlocked state.
[0070] It can be understood that the embodiments of the present disclosure are not limited to the first abutment surface 42a formed on the locking member 42 and the second abutment surface 41a formed on the driving member 41 that abuts against the first abutment surface 42a, so that the driving member 41 can drive the locking member 42 to complete the unlocking or locking. In one embodiment, the driving member 41 is an electromagnet, and at least a portion of the locking member 42 is made of a magnetic material, and the locking unit 4 is switched between the unlocked state and the locked state by attracting or releasing the locking member 42 with the driving member 41.
[0071] In one embodiment, as shown in FIG. 1, the predetermined direction 1a is arranged to be perpendicular to the suction direction of the cleaning body 20.
[0072] In one embodiment, as shown in Figures 3 and 7, the cleaning device further includes a normally closed mechanism 3 attached to the dust cup 21. When the locking unit 4 is in the unlocked state, the normally closed mechanism 3 closes the dust cup cover 22 without the dust cup cover 22 being subjected to an external force, and the dust cup cover 22 can open the dust discharge port 21b against the biasing force of the normally closed mechanism 3 due to the external force.
[0073] In this embodiment, the cleaning system is provided with a normally-closing mechanism 3, which can switch the dust cup cover 22 to a closed state when not subjected to external force. When subjected to external vibration or disturbance during operation of the cleaning device 2, the normally-closing mechanism 3 can apply a force to the dust cup cover 22 to switch it to a closed state, so that the dust cup cover 22 can remain in a closed state and prevent foreign matter from escaping from the dust cup 21.
[0074] It is understood that the embodiments of the present disclosure are not limited to the cleaning device 2 being provided with the normally closed mechanism 3 that closes the dust cup cover 22. In one embodiment, when the cleaning device 2 discharges dust to the base station 1 and the suction mechanism 11 is not activated, the weight of the dust cup cover 22 of the cleaning device causes the dust cup cover 22 to close the dust discharge opening 21b.
[0075] It can be understood that when suction force is generated by the suction mechanism 11, the suction force resists the force applied to the dust cup cover 22 by the normally closed mechanism 3, thereby allowing the dust cup cover 22 to move so as to open the dust discharge port 21b.
[0076] In one embodiment, as shown in Figures 3 and 7, the dust cup cover 22 is pivotally connected to the dust cup 21, and the normally-closing mechanism 3 is an elastic member disposed between the dust cup cover and the dust cup, which applies an elastic force to the dust cup cover so that the dust cup cover remains closed without receiving an external force. In this embodiment, the dust cup cover 22 is pivotally connected to the dust cup 21, and the elastic member, acting as the normally-closing mechanism 3, keeps the dust cup 21 closed when the suction mechanism 11 is not activated. This embodiment of the present disclosure has a simple structure and low cost. Furthermore, after the dust cup cover 22 pivots relative to the dust cup 21 due to the suction force of the suction mechanism 11 to open the dust discharge port 21b, the suction mechanism 11 releases the suction force, allowing the elastic member to more accurately return the dust cup cover 22 to close the dust discharge port 21b.
[0077] In one embodiment, the resilient member is a torsion spring.
[0078] In one embodiment, one torsion arm of the torsion spring abuts against the dust cup 21, and the other torsion arm abuts against the dust cup cover 22, applying a thrust to the dust cup cover 22 toward the first storage chamber 21a. The torsion arm abutting against the dust cup cover 22 abuts against the side of the dust cup cover 22 away from the dust discharge port 21b.
[0079] In one embodiment, the upper end of the dust cup cover 22 is pivotally connected to the dust cup 21 .
[0080] It is understood that the embodiments of the present disclosure are not limited to the dust cup cover 22 being pivotally connected to the dust cup 21 and the normally-closed mechanism 3 being a torsion spring. In one embodiment, the dust cup cover 22 abuts against the dust cup 21, the normally-closed mechanism 3 is a spring, one end of the spring is attached to the dust cup 21, and the other end of the spring is attached to the dust cup cover 22. The spring can apply an elastic force to the dust cup cover 22 toward the first storage chamber 21a so that the dust cup cover 22 closes the dust discharge port 21b.
[0081] In one embodiment, the dust cup 21 is provided with a relief portion 21c, which is located at a position corresponding to the torsion spring in the dust cup 21, and the relief portion 21c is recessed toward the first dust collection chamber 10a.
[0082] In one embodiment, the relief 21c is used to clear the top edge of the dust cup cover 22.
[0083] In this embodiment, the dust cup 21 is formed with an escape portion 21c to avoid the upper end of the dust cup cover 22, allowing the dust cup cover 22 to move smoothly in the process of opening the dust discharge port 21b, and preventing the opening of the dust cup cover 22 from becoming smaller due to interference from the dust cup 21.
[0084] For example, when the cleaning device 2 is performing a dust suction operation, the locking unit 4 is in a locked state, and the locking unit 4 locks the dust cup cover 22 with the dust outlet 21b closed. When the cleaning device 2 completes its operation and foreign matter in the dust cup 21 needs to be removed, the cleaning device 2 moves to the base station 1, and the locking unit 4 is in an unlocked state, and the suction force of the suction mechanism 11 opens the dust cup cover 22, so that the foreign matter in the dust cup 21 is sucked into the base station 1.
[0085] When the locking unit 4 is in the unlocked state, and no other external force is applied, and the cleaning system is provided with a normally closed mechanism 3, the dust cup cover 22 can keep the dust discharge outlet 21b closed by its own weight and the action of the normally closed mechanism 3. It can be understood that when the cleaning system is not provided with a normally closed mechanism 3, the dust cup cover 22 can keep the dust discharge outlet 21b closed by its own weight.
[0086] Embodiment 2 An embodiment of the present disclosure provides a dust suction system, and as shown in FIGS. 8 to 13 , the dust suction system includes a base station 1 and a dust suction mechanism 5. The dust suction mechanism 5 is retractable into the base station 1. When the dust suction mechanism 5 moves to the base station 1, the base station 1 can remove foreign objects in the dust suction mechanism 5.
[0087] In one embodiment, the dust suction mechanism 5 includes a dust suction body 50, a dust cup 21 attached to the dust suction body 50, and a dust cup cover 22 attached to the dust cup 21. The dust cup 21 has a second dust collection chamber 21d capable of collecting foreign matter and a dust outlet 21b communicating with the second dust collection chamber 21d. The dust cup cover 22 can open and close the dust outlet 21b. When the dust suction mechanism 5 moves to the dust discharge position, dust in the second dust collection chamber 21d can be discharged into the collection chamber 10g through the dust outlet 21b. The direction in which dust is discharged from the dust outlet 21b is the dust discharge direction. When projected in the dust discharge direction, at least a portion of the projected area of the dust outlet 21b is located within the projected area of the dust collection port 10b. The dust suction body 50 is used as the base of the dust suction mechanism 5 to mount components of the dust suction mechanism 5, the dust cup 21 is used to receive collected foreign matter, and the dust cup cover 22 is used to close the dust discharge port 21b to prevent foreign matter in the dust cup 21 from escaping through the dust discharge port 21b.
[0088] The dust suction mechanism 5 in the second embodiment is equivalent to the cleaning device 2 in the first embodiment.
[0089] The dust suction main body 50 in the second embodiment is equivalent to the cleaning main body 20 in the first embodiment.
[0090] The second dust collection chamber 21d in the second embodiment is equivalent to the first storage chamber 21a in the first embodiment.
[0091] 11 , the base station 1 includes a dust collecting member 10 and a suction mechanism 11. The dust collecting member 10 has a collection chamber 10g and a dust collection port 10b communicating with the collection chamber 10g. The suction mechanism 11 can generate a suction force toward the dust collection port 10b and the collection chamber 10g. The base station 1 is directly docked to the dust suction mechanism 5 via the dust collecting member 10. After the base station 1 is docked to the dust suction mechanism 5, the second dust collection chamber 21d is opened by the dust cup cover 22. The suction mechanism 11 generates a suction force toward the second dust collection chamber 21d, allowing foreign matter in the dust cup 21 to be sucked into the base station 1.
[0092] 9, the dust suction system further includes a locking unit 4. The locking unit 4 is attached to the dust suction mechanism 5 and has an unlocked state and a locked state. When the locking unit 4 is in the locked state, the locking unit 4 can lock the dust cup cover 22 with the dust outlet 21b closed.
[0093] 9, the dust suction system further includes a normally-opening device 6. The normally-opening device 6 is provided on the dust suction mechanism 5, and when the locking unit 4 is in an unlocked state, the normally-opening device 6 can press the dust cup cover 22 to open the dust outlet 21b.
[0094] In this embodiment, the dust suction system includes a locking unit 4 and a normally-opening device 6. During the dust suction process of the dust suction mechanism 5, the locking unit 4 can lock the dust cup cover 22 with the dust outlet 21b closed to prevent foreign objects sucked into the dust suction mechanism 5 from escaping from the dust cup 21. When the locking unit 4 switches to an unlocked state, the normally-opening device 6 can press the dust cup cover 22 to open the dust outlet 21b. In the absence of any external force, the suction force of the suction mechanism 11 does not need to keep the dust cup cover 22 open, and the dust cup cover 22 can maintain the dust outlet 21b open. The embodiment of the present disclosure solves the problem of unclean cleaning of foreign objects in the dust cup 21.
[0095] The collection chamber 10g in the second embodiment is equivalent to the first dust collection chamber 10a in the first embodiment.
[0096] In one embodiment, when the dust suction mechanism 5 moves to the base station 1, the dust outlet 21b is located within the dust collection opening 10b.
[0097] For example, while the dust suction mechanism 5 is performing a dust suction operation, the locking unit 4 is in a locked state and locks the dust cup cover 22 with the dust outlet 21b closed. When the dust suction mechanism 5 has completed its operation and it is necessary to remove foreign matter from the dust cup 21, the dust suction mechanism moves to the base station 1, the locking unit 4 is in an unlocked state, and the normally-open device 6 opens the dust cup cover 22, thereby sucking the foreign matter from the dust cup 21 into the base station 1.
[0098] In one embodiment, as shown in Figures 1 and 7, the dust cup cover 22 is rotatably connected to the dust cup 21, and the normally-opening device 6 is a third elastic member that is disposed between the dust cup cover 22 and the dust cup 21 so that the dust cup cover 22 can open the dust discharge port 21b by the elastic force of the third elastic member.
[0099] In this embodiment, the dust cup cover 22 is rotatably connected to the dust cup 21, and the third elastic member functions as a normally-opening device 6, causing the dust cup 21 to open the dust discharge port 21b when the locking unit 4 is unlocked. The embodiment of the present disclosure has a simple structure and low cost. Furthermore, after the normally-opening device 6 allows the dust cup cover 22 to rotate relative to the dust cup 21 to open the dust discharge port 21b, the dust cup cover 22 can be more accurately returned to its original position to reclose the dust discharge port 21b.
[0100] In one embodiment, the third elastic member is a torsion spring.
[0101] 7, one torsion arm of the third elastic member abuts against the dust cup 21, and the other torsion arm abuts against the dust cup cover 22, applying a thrust to the dust cup cover 22 toward the first storage chamber 21a. The torsion arm abutting against the dust cup cover 22 abuts against the side of the dust cup cover 22 that is closer to the dust discharge port 21b.
[0102] In one embodiment, the upper end of the dust cup cover 22 is pivotally connected to the dust cup 21 .
[0103] It is understood that the embodiments of the present disclosure are not limited to the dust cup cover 22 being rotatably connected to the dust cup 21 and the normally-opening device 6 being the third elastic member. In one embodiment, the dust cup cover 22 abuts against the dust cup 21, and the normally-opening device 6 is a return spring, one end of which is attached to the dust cup 21 and the other end of which is attached to the dust cup cover 22. The return spring can apply a thrust to the dust cup cover 22 so that the dust cup cover 22 opens the dust discharge port 21b.
[0104] In one embodiment, as shown in FIG. 1, the dust cup 21 has a relief portion 21c formed therein, which is located at a position corresponding to the third elastic member in the dust cup 21 and recessed toward the second dust collecting chamber 21d. The relief portion 21c is used to avoid the upper end of the dust cup cover 22.
[0105] In this embodiment, the dust cup 21 is formed with an escape portion 21c to avoid the third elastic member, allowing the dust cup cover 22 to move smoothly in the process of opening the dust discharge port 21b, and preventing the opening degree of the dust cup cover 22 from becoming smaller due to interference from the dust cup 21.
[0106] In one embodiment, the locking unit 4 is attached to the dust suction body 50 as shown in FIG.
[0107] In this embodiment, the locking unit 4 is mounted on the dust suction body 50. The thickness of the dust cup 21 is thinner than that of the dust suction body 50, and the maximum bearing force that the dust suction body 50 can withstand is greater than that of the dust cup 21. Therefore, by mounting the locking unit 4 on the dust suction body 50, damage to the components of the dust suction system due to long-term use of the locking unit 4 can be avoided.
[0108] It can be understood that the embodiment of the present disclosure is not limited to the locking unit 4 being provided on the dust suction body 50. In one embodiment, the locking unit 4 is provided on the dust cup 21.
[0109] In one embodiment, the dust suction body 50 further comprises a housing, a blower unit, a brush, a battery, and a handle. The dust cup 21, lock unit 4, dust cup cover 22, blower unit, brush, battery, and handle are all mounted in the housing. The battery is electrically connected to the blower unit, which generates suction power to draw external dust and foreign matter through the brush into the housing and collect it in the dust cup 21. The handle allows a user to easily grip and operate the dust suction body.
[0110] In one embodiment, the dust suction body 50 and the dust cup 21 are manufactured separately, and then the dust suction body 50 and the dust cup 21 are manufactured separately and then attached together.
[0111] In one embodiment, the housing and dust cup 21 are manufactured separately and then attached together.
[0112] In one embodiment, as shown in FIG. 1, the dust suction body 50 has an attachment chamber 20a, the dust cup 21 is located within the attachment chamber 20a, the locking unit 4 and the dust cup 21 are aligned in the longitudinal direction of the dust suction body 50, the locking unit 4 is located below the dust cup 21, and the dust suction body 50 is partially supported below the dust cup 21.
[0113] In this embodiment, the locking unit 4 is located below the dust cup 21, and the locking unit 4 moves in the vertical direction 1b to switch between the locked and unlocked states. The locking unit 4 is located below the dust cup 21 to lock the dust cup cover 22, which reduces the installation gap caused by torsional wear of the dust cup cover 22 and ensures that the dust cup cover 22 can stably close the dust discharge port 21b even when used for a long period of time. Note that the embodiment of the present disclosure is not limited to the locking unit 4 being located below the dust cup 21 to lock the dust cup cover 22. In one embodiment, the locking unit 4 is located on the side of the dust cup 21.
[0114] 3, the locking unit 4 includes a second elastic member 43, a driving member 41, and a locking member 42. The second elastic member abuts between the dust suction body and the locking member. The locking member 42 can approach the dust cup cover 22 to lock the dust cup cover 22 with the dust discharge opening 21b closed, and can move away from the dust cup cover 22 so that the normally-open device 6 can press the dust cup cover 22 to open the dust discharge opening 21b. The driving member 41 is used to move the locking member 42 toward or away from the dust cup cover 22.
[0115] In this embodiment, the driving member 41 can move the locking member 42 toward or away from the dust cup cover 22. When the driving member 41 moves the locking member 42 toward the dust cup cover 22, the locking unit 4 switches from an unlocked state to a locked state, and the locking member 42 can lock the dust cup cover 22 so that the dust discharge port 21b remains closed. When the driving member 41 moves the locking member 42 away from the dust cup cover 22, the locking unit 4 switches from a locked state to an unlocked state, and the locking member 42 can release the dust cup cover 22 so that the normally open device 6 opens the dust cup cover 22. Furthermore, the second elastic member 43 presses the locking member 42, and the second elastic member 43 and the locking member 42 together maintain the locked state of the dust cup cover 22, simplifying the unlocking mechanism and reducing costs. The second elastic member 43 makes it easy to switch the locking unit 4 between the locked and unlocked states.
[0116] There is no dependency between the elastic member 40 in embodiment 1 and the third elastic member and the second elastic member 43 in embodiment 2. In fact, the elastic member 40 in embodiment 1 is equivalent to the second elastic member 43 in embodiment 2.
[0117] In one embodiment, the second elastic member 43 and the locking member 42 are arranged in parallel with the longitudinal direction of the dust suction body 50 .
[0118] In one embodiment, the direction in which the second elastic member 43 and the locking member 42 are arranged is parallel to the up-down direction 1b.
[0119] In one embodiment, the second elastic member 43 is located on the side of the locking member 42 away from the dust cup cover 22 .
[0120] 3, the locking member 42 is formed with a first abutment surface 42a, and the distance between the first abutment surface and the second elastic member along the alignment direction of the second elastic member and the locking member is defined as a first distance, which gradually increases along the unlocking direction, so that when the driving member moves along the unlocking direction, the locking unit switches from the locked state to the unlocked state. The driving member 41 is formed with a second abutment surface 41a that abuts against the first abutment surface 42a, and the shape of the second abutment surface 41a matches the shape of the first abutment surface 42a.
[0121] In this embodiment, the first distance gradually increases along the unlocking direction, and the driving member 41 is formed with a second abutment surface 41a that abuts against the first abutment surface 42a. When a force is applied to the driving member 41 from the driving side along the unlocking direction 4a, the first abutment surface 42a and the second abutment surface 41a slide relative to each other, and the locking unit 4 switches from the locked state to the unlocked state.
[0122] It can be understood that the embodiments of the present disclosure are not limited to the first abutment surface 42a formed on the locking member 42 and the second abutment surface 41a formed on the driving member 41 that abuts against the first abutment surface 42a so that the driving member 41 can drive the locking member 42 to complete the unlocking or locking. In one embodiment, the driving member 41 is an electromagnet, and at least a portion of the locking member 42 is made of a magnetic material, and the locking unit 4 is switched between the unlocked state and the locked state by attracting or releasing the locking member 42 with the driving member 41.
[0123] In one embodiment, as shown in FIG. 1, the unlocking direction 4a is arranged to be perpendicular to the suction direction of the dust suction body 50.
[0124] In one embodiment, as shown in Figures 3 and 4, the dust cup cover 22 comprises a main body 220 and a folded edge 221 connected to each other, the folded edge 221 is located at the lower end of the main body 220, an escape groove 20b is formed in the dust suction main body 50, and when the dust cup cover 22 closes the dust discharge port 21b, the folded edge 221 is located in the escape groove 20b.
[0125] In this embodiment, the dust cup cover 22 includes a main body 220 and a folded edge 221 that are connected to each other. The folded edge 221 can limit the main body 220 so that the dust cup cover 22 can switch from opening the dust outlet 21b to closing the dust outlet 21b and engage with the dust cup 21. The folded edge 221 is located at the bottom end of the main body 220. When the dust cup cover 22 is in the state where the dust outlet 21b is closed, the folded edge 221 is located in the escape groove 20b formed in the dust suction main body 50, thereby extending the service life of the dust suction main body 50. If the folded edge 221 is located on the side edge or other position of the main body 220, the folded edge 221 may come into contact with the side wall of the dust suction body 50, which may cause damage or deformation of the side wall of the dust suction body 50 after long-term use. However, according to the embodiment of the present disclosure, the damage to the dust suction body 50 caused by the folded edge 221 can be reduced.
[0126] In one embodiment, as shown in FIG. 4, the body 220 and folded edge 221 are integrally molded.
[0127] In one embodiment, as shown in FIGS. 3 and 4, a positioning hole 221a is formed in the folded edge 221, and when the lock unit 4 is in a locked state, a part of the lock unit 4 is located in the positioning hole 221a.
[0128] In this embodiment, a positioning hole 221a is formed in the folded edge 221, and when the locking unit 4 is in the locked state, a part of the locking unit 4 is located within the positioning hole 221a. The locking unit 4 and the positioning hole 221a engage with each other and limit each other, thereby making the locking of the locking unit 4 to the dust cup cover 22 more secure.
[0129] It should be understood that the embodiment of the present disclosure is not limited to the positioning hole 221a formed in the folded edge 221, and a portion of the locking unit 4 being located within the positioning hole 221a when the locking unit 4 is in the locked state. In one embodiment, the locking unit 4 abuts against the folded edge 221, and the dust cup cover 22 is locked by the frictional force between the locking unit 4 and the folded edge 221.
[0130] In one embodiment, as shown in FIG. 3, when the dust cup cover 22 closes the dust outlet 21b, a portion of the locking member 42 is positioned within the positioning hole 221a.
[0131] In one embodiment, as shown in FIG. 3, a drive surface 41b is formed on one end of the drive member 41 facing the drive side, and the distance between the drive surface 41b and the second elastic member 43 along the alignment direction of the second elastic member 43 and the locking member 42 is defined as a second distance, and the second distance gradually decreases along the unlocking direction 4a. As the dust suction mechanism 5 moves from top to bottom to the dust discharge position, the base station 1 abuts against the drive surface 41b, driving the drive member 41 to move along the unlocking direction 4a relative to the locking member 42, and the locking unit 4 switches from the locked state to the unlocked state.
[0132] In this embodiment, the dust suction mechanism 5 moves from above the base station 1 to the base station 1 from top to bottom, the drive surface 41b can abut against the base station 1, and the base station 1 abuts against the drive surface 41b to move the drive member 41 from the drive side to the other side, and the lock unit 4 switches from the locked state to the unlocked state.
[0133] In one embodiment, as shown in FIG. 3, a guide groove 20c is formed in the dust suction body 50, a portion of the locking member 42 is positioned within the guide groove 20c, and the guide groove 20c extends along the alignment direction of the locking member 42 and the second elastic member 43.
[0134] In this embodiment, a portion of the locking member 42 is positioned within the guide groove 20c, which reduces disturbances in any direction other than the direction in which the locking member 42 and the second elastic member 43 are aligned, making the movement of the locking member 42 more stable. The guide groove 20c also limits the locking member 42, and when the locking member 42 locks the dust cup cover 22 so that the dust discharge port 21b remains closed, the guide groove 20c restricts displacement of the locking member 42 in the unlocking direction 4a, thereby enhancing the cocking effect of the locking unit 44 on the dust cup cover 22.
[0135] In one embodiment, as shown in FIG. 5, the base station 1 further includes an unlocking member 12 provided on the dust collecting member 10, and when the dust suction mechanism 5 moves to the base station 1, the unlocking member 12 abuts against the lock unit 4 to unlock the lock unit 4.
[0136] In this embodiment, when the dust suction mechanism 5 moves to the base station 1, the unlocking member 12 abuts against the lock unit 4 to unlock the lock unit 4. The unlocking means of the embodiment of the present disclosure is simple, and no complicated unlocking device is required.
[0137] 3, one end of the drive member 41 facing the drive side is formed with a drive surface 41b, which slopes from top to bottom along the unlocking direction 4a, with the one end of the drive surface 41b facing the drive side being higher than the other end. The unlocking direction 4a intersects with the longitudinal direction of the dust suction body 50. The drive member 41 is movable relative to the locking member 42 along the unlocking direction 4a, and when the drive member 41 moves from the drive side to the other side, the locking unit 42 switches from the locked state to the unlocked state.
[0138] In this embodiment, the dust suction mechanism 5 moves from above the base station 1 to the base station 1 from top to bottom, the drive surface 41b can abut against the base station 1, and the base station 1 abuts against the drive surface 41b to move the drive member 41 from the drive side to the other side, and the lock unit 4 switches from the locked state to the unlocked state.
[0139] In one embodiment, the unlocking member 12 abuts against the drive surface 41b to unlock the lock unit 4.
[0140] It can be understood that when the dust suction mechanism 5 moves from the side of the base station 1 to the drive side toward the base station 1 along the unlocking direction 4a, the unlocking member 12 abuts against the drive member 41 so that the drive member 41 is displaced along the unlocking direction 4a to unlock the lock unit 4.
[0141] In one embodiment, as shown in FIG. 5, the base station 1 further includes a shielding member 13 provided on the dust collecting member 10, the shielding member 13 being located on the side of the unlocking member 12 facing the lock unit 4, the shielding member 13 being connected to the unlocking member 12, the shielding member 13 and the unlocking member 12 enclosing a shielded chamber, and when the lock unit 4 is in an unlocked state, a portion of the lock unit 4 is located within the shielded chamber 13a.
