Dust collector and cleaning system with same

Abstract

The utility model provides a dust collector and a cleaning system with the same. The vacuum cleaner includes a dirt collection container. The dirt collection container includes a side wall, a door panel, a locking device, and a biasing member. The side wall is provided with an outlet, and dirt in the dirt collecting container is discharged through the outlet. The door plate closes the outlet in the locked state and selectively opens or closes the outlet in the unlocked state. The locking device is kept at the locking position when not triggered so that the door plate can be in the locking state, and the locking device moves to the unlocking position when triggered so that the door plate can be in the unlocking state. Therefore, when the dust collector carries out cleaning work, the door plate is locked at the closing position, so that dirt leakage caused by accidental opening of the door plate is avoided. Moreover, the door plate is matched with the bias part to automatically and timely open or close the outlet, and an operator does not need to execute additional operation, so that the operation is relatively convenient.

Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of cleaning equipment, and more particularly, to a dust collector and a cleaning system having the same. BACKGROUND

[0002] Dust collectors cooperating with a base station are known. When performing a cleaning task, the dust collector is detached from the base station, and a door panel of a dirt collection container on the dust collector is in a closed position to close the dirt collection container and prevent dust and dirt in the dirt collection container from leaking to the outside environment. After the cleaning task is completed, the dust collector is docked to the base station; at this time, the door panel of the dirt collection container needs to be switched to an open position to enable the dirt in the dirt collection container to be unloaded into a staging chamber in the base station. The door panel of the conventional dust collector has a risk of being accidentally opened when performing a cleaning task, and the operation of opening or closing the door panel is inconvenient. SUMMARY

[0003] Therefore, the present application provides a dust collector and a cleaning system having the same to at least solve the problem that the conventional dust collector has a risk of the door panel being accidentally opened when performing a cleaning task, or the operation of opening the door panel when docking with the base station and closing the door panel when detaching from the base station is inconvenient.

[0004] In one aspect, the present disclosure provides a dust collector.

[0005] The dust collector includes a dirt collection container. The dirt collection container includes a side wall, a door panel, a locking device, and a biasing member. The side wall has an outlet through which dirt in the dirt collection container is unloaded. The door panel closes the outlet in a locked state and selectively opens or closes the outlet in an unlocked state. The locking device is maintained in a locked position to enable the door panel to be in the locked state when the locking device is not triggered, and the locking device is moved to an unlocked position to enable the door panel to be in the unlocked state when the locking device is triggered. The biasing member biases the door panel toward a position in which the outlet is closed.

[0006] As one possible implementation, the dirt collection container further includes a bottom wall. The bottom wall and the side wall at least partially enclose a dust collection chamber that contains the dirt, and the bottom wall at least partially provides support for the dirt in the dust collection chamber. One end of the door panel is pivotably connected to the side wall about an axis, and the other end selectively abuts against or moves away from the bottom wall. The door panel is pivoted about the axis to switch between a position in which the outlet is opened and a position in which the outlet is closed.

[0007] As one possible implementation, the dirt collection container further includes a bottom wall. The bottom wall and the side wall at least partially enclose a dust collection chamber that contains the dirt, and the bottom wall at least partially provides support for the dirt in the dust collection chamber. One end of the door panel is pivotably connected to the side wall about an axis, and the other end selectively abuts against or moves away from the bottom wall. The door panel is pivoted about the axis to switch between a position in which the outlet is opened and a position in which the outlet is closed.

[0008] As a possible implementation, the locking device includes a moving member, a resilient member, and a blocking member. The moving member is movably connected to the side wall between a locking position and an unlocking position. The resilient member biases the moving member toward the locking position. The blocking member blocks the door panel from pivoting to a position toward the opening outlet when the moving member is in the locking position. When the cleaner is docked with the base, the moving member is triggered by the triggering member of the base to move from the locking position to the unlocking position against the biasing force from the resilient member, so that the door panel is released from the blocking of the blocking member and can pivot to the position toward the opening outlet under the pushing of the suction airflow from the transfer chamber to the base against the biasing force from the biasing member.

[0009] As a possible implementation, one end of the door panel is pivotally connected to the moving member so that the door panel is pivotally connected to the side wall and moves with the moving member, and the blocking member is fixed to or formed integrally with the bottom wall. When the moving member is in the locking position, the door panel is in a position blocked by the blocking member. When the moving member is in the unlocking position, the door panel is in a position released from the blocking of the blocking member.

[0010] As a possible implementation, one of the door panel and the moving member is provided with a shaft portion defining an axis, and the other is provided with a shaft hole supporting the shaft portion.

[0011] As a possible implementation, the shaft hole is a long hole, the shaft portion is slidable along the length direction of the long hole, and the length direction of the long hole is parallel to the moving direction of the moving member between the unlocking position and the locking position.

[0012] As a possible implementation, the moving member includes an end plate portion. When the cleaner is docked with the base, the triggering member of the base triggers the moving member by abutting against the end plate portion. When the moving member is in the locking position, the inner end surface of the end plate portion and the end surface of one end of the door panel are in abutment, and both the inner end surface of the end plate portion and the end surface of one end of the door panel are outwardly inclined in a direction approaching the other end of the door panel.

[0013] As a possible implementation, the moving member is integrally formed with or assembled with the blocking member to move together. One end of the door panel is connected to the side wall, and the other end of the door panel is selectively abutted against or away from the bottom wall. When the moving member is in the locking position, the blocking member is located inside and abuts against one end of the door panel. When the moving member is in the unlocking position, the blocking member is released from abutting against one end of the door panel.

[0014] As a possible implementation, the moving member is integrally formed with or assembled with the blocking member to move together. One end of the door panel is connected to the bottom wall, and the other end of the door panel is selectively abutted against or away from the side wall. When the moving member is in the locking position, the blocking member is located outside and abuts against one end of the door panel. When the moving member is in the unlocking position, the blocking member is released from abutting against one end of the door panel.

[0015] In another aspect, the present disclosure also provides a cleaning system. The cleaning system comprises the above-mentioned dust collector and a base station. The base station is provided with an inlet, a transfer chamber, a trigger member and a suction source. When the dust collector is docked with the base station, the locking device is triggered by the trigger member to switch from the locking position to the unlocking position. When the dust collector is docked with the base station and the suction source is running, the door plate is pushed by the suction airflow generated by the suction source to switch from the position closing the outlet to the position opening the outlet to form an airflow path from the outlet and the inlet to the transfer chamber, against the biasing force from the biasing member.

[0016] When the dust collector of the present embodiment is in the working state, the door plate is in the locking state and is located at the position closing the outlet of the dirt collection container. The door plate is kept in the locking state by the locking device, preventing the dirt in the dirt collection container from leaking to the outside environment due to accidental opening of the door plate. When the dust collector is docked with the base station, the locking device is triggered to move to the unlocking position, so that the door plate is in the unlocking state, i.e., in the state of being able to be selectively opened or closed. Due to the presence of the biasing member, the door plate will remain in the position closing the outlet during the unlocking process, i.e., during the docking process of the dust collector and the base station, to prevent the dirt from leaking. After the dust collector is docked with the base station, the door plate is automatically opened to allow the dirt to be unloaded from the dirt collection container into the transfer chamber of the base station under the push of the suction airflow from the dirt collection container of the dust collector to the transfer chamber of the base station, against the biasing force of the biasing member. After the unloading is completed, the suction airflow stops, and the door plate will return to the position closing the outlet under the action of the biasing member. When the operator performs cleaning work again, the locking device will reset to the locking position due to the separation from the trigger member on the base station, thereby locking the door plate which has been in the closed position again. Accordingly, during the cleaning work, the door plate will be locked in the closed position to prevent the dirt from leaking due to accidental opening of the door plate. Moreover, the door plate will automatically open or close the outlet in time by cooperating with the biasing member, without the need for the operator to perform additional operations, thus being more convenient to operate.

[0017] In addition, the operator may accidentally touch the locking device when using the dust collector, causing the door plate to accidentally switch to the unlocking state. In this case, due to the presence of the biasing member, the door plate will be biased towards the position closing the outlet and be kept in the closed position. This means that even if the operator accidentally touches the locking device to cause the door plate to switch to the unlocking state, if there is not enough external force to apply force to the door plate towards the position opening the outlet to overcome the biasing force applied to the door plate by the biasing member, the door plate will not move to the position opening the outlet. This effectively reduces the risk of dirt leakage due to accidental touching of the locking device. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0031] Numerous specific details are set forth in the following description in order to provide a thorough understanding of the structure, function and use of the embodiments described and shown in the specification. It will be appreciated that the embodiments described and shown are non-limiting examples and that specific structural and functional details disclosed herein can be representative and exemplary. Variations and changes can be made to these embodiments without departing from the scope of the claims.

[0032] <Example cleaning system>

[0033] The embodiments of the present disclosure provide a cleaning system. In order to facilitate understanding, the overall structure of the cleaning system according to the present disclosure will be described first. It should be understood that the structure of the cleaning system should not be limited to the following description. For example, one or more elements introduced below can be omitted or replaced, and the layout relationship therebetween can be replaced.

[0034] Reference Figure 1 and Figure 2 The cleaning system includes a cleaner 100 and a base station 200. The cleaner 100 includes a dirt collection container 10 for collecting dirt sucked by the cleaner 100. The dirt collection container 10 includes a side wall 11 and a door panel 12. The side wall 11 has an outlet 112 through which dirt in the dirt collection container 10 can be discharged. The door panel 12 can be provided at the outlet 112. When the cleaner 100 is in a working state, dirt enters the dirt collection container 10 through a suction inlet of the cleaner 100. At this time, as shown in FIG. 1, the door panel 12 is closed, and the outlet 112 is closed. When the cleaner 100 is in a non-working state, the door panel 12 is opened, and the outlet 112 is opened. Figure 2 and Figure 4As shown, the door panel 12 is in a locked state. In this locked state, the door panel 12 is positioned to close the outlet 112, thus closing the outlet 112 of the waste collection container 10. The position for closing the outlet 112 is as follows: Figure 2 The location of the middle door panel 12 isolates the waste collection container 10 from the external environment to prevent the waste inside the waste collection container 10 from being exposed to the external environment.

[0035] like Figure 1 As shown, the base station 200 includes an inlet 201, a storage chamber 202, a suction source 203, and a trigger 204. The storage chamber 202 of the base station 200 has an internal space for storing waste sucked from the waste collection container 10. The suction source 203 of the base station 200 can be any device that generates suction airflow, such as an electric motor, a centrifugal fan, etc. When the vacuum cleaner 100 docks with the base station 200, the locking device 101 is triggered by the trigger 204 and switches from a locked position to an unlocked position. The inlet 201 of the base station 200 is connected to the outlet 112 of the waste collection container 10. At this time, the door panel 12 is in an unlocked state, and in the unlocked state, the door panel 12 can selectively open or close the outlet 112. Specifically, when the suction source 203 is running, the door panel 12 can be moved from a position where the outlet 112 is closed to a position where the outlet 112 is open, driven by the suction airflow generated by the suction source 203. Figure 1 The position of the middle door panel 12 is such that an airflow path is formed from the outlet 112 of the waste collection container 10 to the inlet 201 of the base station 200, which draws the waste in the waste collection container 10 into the transfer chamber 202.

[0036] <Example vacuum cleaner>

[0037] like Figures 1-4 As shown, the waste collection container 10 of the vacuum cleaner 100 includes a locking device 101. The locking device 101 remains in the locked position when not triggered, and moves from the locked position to the unlocked position when triggered. The triggering process can be understood as an external force input process; during this process, the locking device 101 moves from the locked position to the unlocked position under the action of an external force. The external force referred to here can include the force from the base station 200 experienced by the vacuum cleaner 100 when docking with the base station 200. For example, when not performing cleaning work, the operator can place the vacuum cleaner 100 on the base station 200 and dock the vacuum cleaner 100 with the base station 200; during the docking process, as the vacuum cleaner 100 is positioned relative to the base station 200, a part of the base station 200 can come into contact with the locking device 101, pushing the locking device 101 to move relative to the base station 200. Figure 2 The locked position is moved to Figure 3the unlocking position, the process of which can be referred to as the locking device 101 being triggered by the base station 200; when the operator picks up the cleaner 100 from the base station 200 again, the locking device 100 no longer interferes with the base station 200, and no external force is applied to the locking device 100, the locking device 100 is not triggered, and it will be reset to the Figure 3 locking position in the unlocking position. How the base station 200 triggers the locking device 101 and how the locking device 101 maintains and resets to the locking position when it is not triggered will be described below, and will not be described here. Figure 2

[0038] When the locking device 101 is not triggered, the door plate 12 cannot open the outlet 112. That is, when the door plate 12 is in the locked state, the door plate 12 can only be in the position of closing the outlet 112, preventing the dirt from being unloaded from the outlet 112. The door plate 12 can optionally open or close the outlet 112 in the unlocked state. That is, in the unlocked state, the door plate 12 can move between the position of closing the outlet 112 and the position of opening the outlet 112, and the door plate 12 can move from the position of closing the outlet 112 to the position of opening the outlet 112, and can also move from the position of opening the outlet 112 to the position of closing the outlet 112. The movement of the door plate 12 can include but is not limited to translation, pivoting, swinging, and the like, as long as the movement can switch the door plate 12 between the position of opening the outlet 112 and the position of closing the outlet 112. When the cleaner 100 is docked with the base station 200, the locking device 101 can be triggered by the base station 200 to move to the unlocking position, so that the door plate 12 is in the unlocked state. The door plate 12 in the unlocked state can be in the position of closing the outlet 112, and can move to the position of opening the outlet 112 under the action of the suction airflow of the base station 200. When the door plate 12 is in the position of opening the outlet 112, the dirt in the dirt collection container 10 can be unloaded through the outlet 112. After the unloading is completed, the suction airflow stops, and the door plate 12 can return to the position of closing the outlet 112.

[0039] ​In the above embodiments, the operator can easily touch the locking device 101 by mistake when using the dust collector 100, and the door plate 12 is in the unlocked state. At this time, the door plate 12 can move to the position of opening the outlet 112 only under the action of its own gravity, and the dirt in the dirt collection container 10 can easily leak out from the outlet 112, polluting the external environment. Therefore, the dirt collection container 10 further comprises a biasing member 60, which biases the door plate 12 towards the position of closing the outlet 112. That is, the biasing member 60 applies a persistent biasing force F2 to the door plate 12 towards the position of closing the outlet 112, so as to keep the door plate 12 in the position of closing the outlet 112. And, the door plate 12 always has a tendency to move towards the position of closing the outlet 112 under the action of the biasing member 60. That is, the door plate 12 automatically returns to the position of closing the outlet 112 without external force, ensuring the automatic closing of the door plate 12. This means that even if the operator touches the locking device 101 by mistake and the door plate 12 is in the unlocked state, the door plate 12 will not move to the position of opening the outlet 112 without sufficient external force applied to the door plate 12 towards the position of opening the outlet 112 to overcome the biasing force applied by the biasing member 60 to the door plate 12. This effectively reduces the risk of dirt leakage due to touching the locking device 101 by mistake.

[0040] Due to the presence of the biasing member 60, the door plate 12 will remain in the position of closing the outlet 112 during the unlocking process, i.e. during the docking process of the dust collector 100 and the base station 200, to avoid the leakage of dirt. After the docking of the dust collector 100 and the base station 200, the door plate 12 automatically opens the outlet under the pushing of the suction airflow from the dirt collection container 10 of the dust collector 100 to the transfer chamber 202 of the base station 200, allowing the dirt to be unloaded from the dirt collection container 10 into the transfer chamber 202, overcoming the biasing force of the biasing member 60. After the unloading is completed, the suction airflow stops, and the door plate 12 will return to the position of closing the outlet 112 under the action of the biasing member 60. When the operator performs cleaning work again, the locking device 101 is reset to the locked position by separating from the trigger 204 on the base station 200 when the dust collector 100 is lifted from the base station 200, thereby locking the door plate which has been in the closed position again. Accordingly, the door plate 12 will be locked in the closed position during the cleaning work to avoid the leakage of dirt due to the accidental opening of the door plate 12. And, the door plate 12 will automatically open or close the outlet in time by cooperating with the biasing member 60, without the need for the operator to perform additional operations, thus being more convenient to operate.

[0041] As Figures 3-8As shown, the dirt collection container 10 further comprises a bottom wall 15, which, together with the side wall 11, at least partially encloses a dust collection chamber 111 for receiving dirt. When the dirt enters the dust collection chamber 111, it will fall onto the bottom wall 15 under the action of gravity, and the bottom wall 15 at least partially supports the dirt in the dust collection chamber 111. One end of the door panel 12 is pivotally connected to the side wall 11 about an axis 20, and the other end selectively abuts against or leaves the bottom wall 15. In one embodiment, one end of the door panel 12 is pivotally connected to the side wall 11 about an axis 20, and the other end of the door panel 12 selectively abuts against or leaves the bottom wall 15. In other words, both ends of the door panel 12 are close to the bottom wall 15 and the side wall 11, respectively. This arrangement has the advantage that the outlet 112 can be close to the bottom wall 15, and the door panel 12 can be pivoted about the axis 20 to switch between the position of opening the outlet 112 and the position of closing the outlet 112, so that the dirt on the bottom wall 15 is more easily sucked out of the outlet 112 by the suction airflow, and the requirement for the strength of the suction airflow can be reduced. Meanwhile, after the dirt close to the bottom wall 15 is sucked away, the dirt located at the upper layer of the dust collection chamber 111 will also fall onto the bottom wall 15 under the action of gravity, so that the dirt in the dust collection chamber 111 is completely sucked away.

[0042] As shown in Figure 3 and Figure 4 The locking device 101 comprises a moving member 40, a resilient member 61 and a blocking member 50. The moving member 40 is movably connected to the side wall 11 between a locking position and an unlocking position. For example, a sliding groove can be provided on the side wall 11, and a sliding block is provided on the moving member 40. The resilient member 61 biases the moving member towards the locking position, that is, the resilient member 61 exerts a biasing force on the moving member towards the locking position. When the moving member 40 is in the locking position, the door panel 12 is in the position of closing the outlet 112, and the blocking member 50 blocks the door panel 12 from pivoting towards the position of opening the outlet 112. At this time, due to the blocking of the blocking member, the door panel 12 can only be in the position of closing the outlet 112, and cannot open the outlet 112.

[0043] As shown in Figure 3As shown, when the cleaner 100 is docked with the base station 200, the moving member 40 is triggered by the triggering member 204 of the base station 200, and moves from the locked position to the unlocked position against the biasing force Fl from the elastic member 61, where the biasing force Fl is directed from the unlocked position to the locked position. The door panel 12 is released from the blocking of the blocking member 50 in a number of ways, including but not limited to, the moving member 40 moving causing the door panel 12 to move such that the door panel 12 is displaced relative to the blocking member 50 and is thereby released from the blocking. The moving member 40 moving causing the blocking member 50 to move such that the blocking member 50 is displaced relative to the door panel 12 and the door panel 12 is thereby released from the blocking of the blocking member 50. As shown in Figure 3 As shown, after the door panel 12 is released from the blocking of the blocking member 50, the door panel 12 is in the unlocked state; at this time, with the operation of the suction source 203 of the base station 200, a suction airflow from the dust collection chamber 111 to the staging chamber 202 of the base station 200 will be generated, and the airflow path is shown by a plurality of solid arrows in the figure. Under the push of the airflow, the door panel 12 will be pivoted about the axis 20 in a direction opposite to the biasing force F2 of the biasing member 60, i.e. from the position of the closed outlet 112 in Figure 2 to the position of the open outlet 112 in Figure 3 In the current example, as viewed from the perspective of Figure 2 and Figure 3 , the biasing force F2 is a force in the clockwise direction about the axis 20, and the push force exerted on the door panel by the airflow is a force in the counterclockwise direction about the axis 20. The dirt in the dust collection chamber 111 is transferred from the dust collection chamber 111 to the staging chamber 202 under the action of the suction airflow. After the dirt in the dust collection chamber 111 is suctioned clean, the door panel 12 is pivoted from the position of the open outlet 112 to the position of the closed outlet 112 under the action of the biasing member 60. After the cleaner is removed from the base station, the moving member is released from the triggering member 204 of the base station 200. The moving member moves from the unlocked position to the locked position under the action of the elastic member 61.

[0044] For an embodiment in which the moving member 40 moving causes the door panel 12 to move. As shown in Figure 3 and Figure 4 , one end of the door panel 12 is pivotally connected to the moving member 40 such that the door panel 12 is pivotally connected to the side wall 11 and moves with the moving member 40. The blocking member 50 is fixed to or formed integrally with the bottom wall 15. When the moving member 40 is in the locked position, the door panel 12 is in the position blocked by the blocking member 50. When the moving member 40 is in the unlocked position, the door panel 12 is in the position released from the blocking of the blocking member 50.

[0045] Specifically, the door panel 12 has opposite first and second end portions 121 and 122, the first end portion 121 can be an upper end portion, and the second end portion 122 can be a lower end portion. The first end portion 121 of the door panel 12 is pivotally connected to the moving member 40 and moves with the moving member 40. The side wall 11 is provided with a first recess 13 and a second recess 14, and the moving member 40 includes a first surface 41, a second surface 42, a third surface 43 and a fourth surface 44. The first surface 41 is slidably connected to a bottom wall 131 of the first recess 13, and the third surface 43 is slidably connected to a bottom wall 141 of the second recess 14, so that the door panel 12 is indirectly pivotally connected to the side wall 11. The second surface 42 is provided with a protrusion 70, and the shape of the protrusion 70 is not limited in the present application, for example, it can be cylindrical, rectangular, etc. One end of the elastic member 61 is sleeved on the protrusion 70, and the protrusion 70 can limit the displacement of the elastic member 61 in the direction parallel to the second surface 42. The other end of the elastic member 61 can abut against the side wall 132 of the first recess 13. A containing space for containing the elastic member 61 can also be provided on the side wall 11, the other end of the elastic member 61 extends into the containing space, and the side wall of the containing space can limit the displacement of the elastic member 61 in the direction parallel to the second surface 42. The elastic member 61 can be a component with elasticity, such as a spring, a compression spring, etc. When the elastic member 61 is a component with elasticity, the elastic member 61 can be in a compressed state, and the biasing direction of the moving member 40 is towards the locking position.

[0046] The biasing member 60 can be a component with elasticity, such as a spring, a torsion spring, etc. When the elastic component is a torsion spring, the torsion spring can be coaxial with the axis 20. One end of the torsion spring can be fixed on the moving member 40, and the other end can be fixed on the door panel 12, so as to apply a force to the door panel 12 towards the position closing the outlet 112, so that the door panel 12 can automatically return to the position closing the outlet 112 after the suction airflow of the base station 200 stops. When the elastic component is a spring, one end of the spring can be fixed on the moving member 40, and the other end can be fixed on the door panel 12, and the spring can be in a stretched state to bias the door panel 12 towards the position closing the outlet 112.

[0047] The blocking member 50 is fixed to or formed integrally with the bottom wall 15. The blocking member 50 blocks the pivoting of the door plate 12 towards the position of the open outlet 112 by abutting against the second end portion 122, and comprises a third recess 51. When the moving member 40 is in the locked position, the door plate 12 is in the position of the closed outlet 112, and the second end portion 122 of the door plate 12 extends into the third recess 51, and the side wall of the third recess 51 can block the movement of the door plate 12 from the position of the closed outlet 112 to the position of the open outlet 112, so as to prevent the dust in the dust collecting chamber 111 of the dirt collection container 10 from being exposed to the external environment when the cleaner 100 is working. When the moving member 40 is in the unlocked position, the second end portion 122 of the door plate 12 is outside the third recess 51, and is free from the blocking of the side wall of the third recess 51, and can be pivoted to the position of the open outlet 112.

[0048] One of the door plate 12 and the moving member 40 can be provided with a shaft portion 21 defining an axis 20, and the other can be provided with a shaft hole 22 supporting the shaft portion 21, so that the door plate 12 can be pivoted about the axis 20 to switch between the position of the open outlet 112 and the position of the closed outlet 112. Specifically, the door plate 12 is provided with the shaft portion 21 defining the axis 20. The first end portion 121 of the door plate 12 can be fixedly connected with the shaft portion 21, for example, a shaft rod, the surface of the door plate 12 can be tangent to the surface of the shaft rod, and the door plate 12 can be integrally formed with the shaft portion 21. The moving member 40 is provided with the shaft hole 22, and the shaft portion 21 is arranged in the shaft hole 22 and rotatable relative to the shaft hole 22. The shaft portion 21 can be rotated relative to the shaft hole 22 to rotate the door plate 12, so as to switch the door plate 12 between the position of the open outlet 112 and the position of the closed outlet 112. As another embodiment, the shaft portion 21 can be fixedly connected with the moving member 40. The first end portion 121 of the door plate 12 can be provided with the shaft hole 22, and the shaft portion 21 is arranged in the shaft hole 22 and rotatable relative to the shaft hole 22, so as to switch the door plate 12 between the position of the open outlet 112 and the position of the closed outlet 112. When the moving member 40 moves between the locked position and the unlocked position, the shaft hole 22 or the shaft portion 21 on the moving member 40 can drive the door plate 12 to move synchronously.

[0049] In the above embodiment, the moving member 40 can drive the door plate 12 to move synchronously through the cooperation of the shaft hole 22 and the shaft portion 21. However, during the daily cleaning process of the cleaner 100, the operator is likely to accidentally touch the moving member 40, so that the moving member 40 moves a small distance from the locked position towards the unlocked position. If the door plate 12 and the moving member 40 move synchronously, the movement of the door plate 12 caused by the accidental touch of the moving member 40 can cause the door plate 12 to move out of the blocking of the blocking member 50, and the dirt collection container 10 is opened, and the dust in the dirt collection container 10 is exposed to the external environment. Therefore, referring to Figure 4As shown, the shaft hole 22 can be an elongated hole, with a length greater than its width. The shaft portion 21 can slide relative to the shaft hole 22 along the length direction of the elongated hole, and the length direction of the elongated hole is parallel to the movement direction of the moving member 40 between the unlocked and locked positions. Specifically, the elongated hole can be provided on the moving member 40. When the moving member 40 is in the locked position, the shaft portion 21 abuts against the first end of the elongated hole, which can be the upper end of the elongated hole. There is a gap L between the second end (lower end) of the elongated hole and the shaft portion 21. When the moving member 40 is subjected to an external force and moves towards the unlocked position, the shaft portion 21 remains stationary, and the elongated hole first slides upward relative to the shaft portion 21 a certain distance. The sliding distance depends on the size of the aforementioned gap L. When the elongated hole slides relative to the shaft portion 21, the door panel 12 does not move until the second end of the elongated hole contacts the shaft portion 21. That is, the door panel 12 will only move when the moving member 40 moves a distance greater than the aforementioned gap L. Therefore, even if the operator accidentally touches the moving part 40 during the cleaning process, the displacement generated by the moving part 40 is insufficient to cause the door panel 12 to move, or the displacement is small and insufficient to cause the door panel 12 to break free from the obstruction of the blocking part 50. This can effectively prevent accidental contact with the moving part 40 from causing the dirt collection container 10 to open unexpectedly.

[0050] like Figure 4 As shown, the movable member 40 also includes an end plate portion 46. When the movable member 40 is in the locked position, the inner end face 461 of the end plate portion 46 is in contact with the end face of one end of the door panel 12, for example, with the end face 1211 of the first end. Both the inner end face 461 of the end plate portion 46 and the end face of one end of the door panel 12 are inclined outward in a direction approaching the end face of the other end of the door panel 12, which may be the second end 122. When the movable member 40 is in the locked position, the second end 122 of the door panel 12 abuts against the side wall of the third groove 51 to close the outlet 112. At this time, the inner end face 461 of the end plate portion 46 is in contact with the end face 1211 of the first end, thereby preventing the door panel 12 from pivoting clockwise as shown in the figure, thus preventing the second end 122 from disengaging from the side wall of the third groove 51 and avoiding the formation of a path for dirt leakage between the two. When the vacuum cleaner 100 docks with the base station 200, the trigger 204 of the base station 200 abuts against the end plate 46, while the trigger moving member 40 moves upward from the locked position to the unlocked position. During this process, the moving member 40 is displaced first, while the door panel 12 remains stationary. At this time, the inner end face 461 of the end plate 46 and the end face 1211 of the first end are separated from each other, providing sufficient space for the door panel 12 to rotate, avoiding interference between the moving member 40 and the door panel 12, so that the door panel 12 can rotate from the closed outlet 112 position to the open outlet 112 position.

[0051] As the moving member 40 moves from the locked position to the unlocked position, the door panel 12 moves in a direction from the second end 122 to the first end 121, i.e. upward, so that the second end 122 of the door panel 12 is disengaged from the abutment of the blocking member 50. When the moving member 40 is in the unlocked position, the fourth surface 44 abuts against the side wall 142 of the second recess, which can limit further displacement of the moving member 40 so that the moving member 40 stays in a predetermined position. At this time, the suction source 203 of the cleaner 100 is turned on, and the suction airflow causes the door panel 12 to rotate counterclockwise about the axis 20 from the position closing the outlet 112 to the position opening the outlet 112, with the door panel 12 partially extending into the airflow passage of the base station 200 to form an airflow path from the dirt collection container 10 through the outlet 112 and the inlet 201 of the base station 200 to the holding chamber 202, so that dust in the dirt collection container 10 is sucked into the holding chamber 202. When the suction source 203 of the cleaner 100 is turned off, the door panel 12 rotates clockwise about the axis 20 from the position opening the outlet 112 to the position closing the outlet 112 under the action of the biasing member 60, so that the dirt in the dirt collection container 10 is isolated from the external environment. When the cleaner 100 is removed from the base station 200, the moving member 40 is disengaged from the abutment with the trigger 204. The moving member 40 moves downward from the unlocked position to the locked position under the action of the resilient member 61. The moving member 40 drives the door panel 12 to move downward through the cooperation of the shaft hole 22 and the shaft portion 21 until the second end 122 extends into the third recess 51 of the blocking member 50. The blocking member 50 blocks the pivoting of the door panel 12 toward the position opening the outlet 112.

[0052] For an embodiment in which the moving of the moving member 40 causes the moving of the blocking member 50, as shown in Figs. 2 and 3, the moving member 40 is integrally formed with or assembled with the blocking member 50 to move together. One end of the door panel 12 is connected to the side wall 11, and the other end of the door panel 12 is selectively abutted against or disengaged from the bottom wall 15. When the moving member 40 is in the locked position, the blocking member 50 is located inside the one end of the door panel 12 and abuts against the one end of the door panel 12. When the moving member 40 is in the unlocked position, the blocking member 50 is disengaged from the abutment with the one end of the door panel 12. Figure 5 and Figure 6 For an embodiment in which the moving of the moving member 40 causes the moving of the blocking member 50, as shown in Figs. 2 and 3, the moving member 40 is integrally formed with or assembled with the blocking member 50 to move together. One end of the door panel 12 is connected to the side wall 11, and the other end of the door panel 12 is selectively abutted against or disengaged from the bottom wall 15. When the moving member 40 is in the locked position, the blocking member 50 is located inside the one end of the door panel 12 and abuts against the one end of the door panel 12. When the moving member 40 is in the unlocked position, the blocking member 50 is disengaged from the abutment with the one end of the door panel 12.

[0053] Specifically, the door panel 12 includes a first end 121 pivotally connected to the side wall 11 and a second end 122 selectively abutted against or disengaged from the bottom wall 15. The first end 121 and the moving member 40 are located on a first side of the axis 20, and the second end 122 and the outlet 112 are located on a second side of the axis 20 opposite the first side. When the moving member 40 is in the locked position, the blocking member 50 is located inside the first end 121 and abuts against the first end 121. When the moving member 40 is in the unlocked position, the blocking member 50 is disengaged from the abutment with the first end 121.

[0054] The side wall 11 is provided with a first groove 13 and a second groove 14. The moving part 40 comprises a first surface 41, a second surface 42, a third surface 43, a fourth surface 44 and a fifth surface 45. The second surface 42 is provided with a protrusion 70. The present application does not limit the shape of the protrusion 70. For example, the protrusion 70 can be cylindrical, rectangular or the like. One end of the elastic part 61 is sleeved on the protrusion 70. The protrusion 70 can limit the displacement of the elastic part 61 in the direction parallel to the second surface 42. The other end of the elastic part 61 can abut against the side wall 132 of the first groove. A containing space for containing the elastic part 61 can also be provided on the side wall 11. The other end of the elastic part 61 extends into the containing space. The side wall of the containing space can limit the displacement of the elastic part 61 in the direction parallel to the second surface 42. The elastic part 61 can be a component with elasticity, such as a spring, a compression spring or the like. When the elastic part 61 is a component with elasticity, the elastic part 61 can be in a compressed state. The biasing direction of the moving part 40 is towards the locked position. The third surface 43 is in abutment with the bottom wall 141 of the second groove 14. The moving part 40 moves upwards from the locked position to the unlocked position and moves downwards from the unlocked position to the locked position. When the moving part 40 is in the unlocked position, the fourth surface 44 abuts against the side wall 142 of the second groove 14.

[0055] The first end 121 of the door plate 12 is an upper end, and the second end 122 is a lower end. The door plate 12 can be pivoted about an axis 20. The axis 20 is above the outlet 112 and the first end 121. The axis 20 can be the axis 20 of the shaft part 21. The shaft part 21 is between the first end 121 and the second end 122. The first end 121 and the moving part 40 are on a first side of the axis 20. The second end 122 and the outlet 112 are on a second side of the axis 20 opposite the first side. The shaft part 21 can be a shaft rod. The side wall 11 can be provided with a shaft hole 22 (not shown in the figure). The shaft rod can extend into the shaft hole 22 and rotate relative to the shaft hole 22. The door plate 12 can be fixedly connected with the shaft rod. When the shaft rod rotates, the door plate 12 can be driven to rotate. As another embodiment, the shaft rod can be fixedly connected with the side wall 11. The shaft rod is perpendicular to the first surface 41 and the second surface 42. The shaft hole 22 can be provided on the door plate 12 to achieve the pivoting of the door plate 12 about the axis 20. The biasing part 60 can be a torsion spring. The torsion spring can be sleeved on the shaft part 21. One end of the torsion spring can abut against the side wall 11, and the other end can abut against the first end 121 to apply a force to the door plate 12 towards the position closing the outlet 112. The biasing part 60 can also be a spring. One end of the spring can be fixed to the side wall 11, and the other end can be fixed to the first end 121. The spring can be in a compressed state to apply a force to the door plate 12 towards the position closing the outlet 112. After the suction airflow of the base station 200 stops, the door plate 12 can automatically recover to the position closing the outlet 112.

[0056] The blocking member 50 is a protrusion formed on the fifth surface 45. When the moving member 40 is in the locked position, the blocking member 50 is located inside the first end portion 121, i.e. between the first end portion 121 and the bottom wall 131 of the first recess 13, and abuts against the first end portion 121 to prevent the door panel 12 from being rotated counterclockwise. When the moving member 40 is pushed upward by the triggering member 204 of the base station 200 to move from the locked position to the unlocked position, the moving member 40 brings the blocking member 50 to move upward until the blocking member 50 is disengaged from the first end portion 121. At this time, the door panel 12 can be rotated counterclockwise to the position in which the outlet 112 is opened under the action of the suction air flow. When the suction source 203 of the cleaner 100 is turned off, the door panel 12 is rotated clockwise from the position in which the outlet 112 is opened to the position in which the outlet 112 is closed under the action of the biasing member 60 to isolate the dirt in the dirt collection container 10 from the outside environment. When the cleaner 100 is removed from the base station 200, the moving member 40 is disengaged from the triggering member 204. The moving member 40 is moved downward from the unlocked position to the locked position under the action of the elastic member 61. The blocking member 50 is also moved downward until it abuts against the first end portion 121.

[0057] For another embodiment in which the movement of the moving member 40 causes the blocking member 50 to move, as shown in Figs. 2 and 3, the moving member 40 and the blocking member 50 are integrally formed or assembled together to move as a whole. One end of the door panel 12 is connected to the bottom wall 15, and the other end of the door panel 12 selectively abuts against or leaves the side wall 11. When the moving member 40 is in the locked position, the blocking member 50 is located outside the one end of the door panel 12 and abuts against the one end of the door panel 12. When the moving member 40 is in the unlocked position, the blocking member 50 is disengaged from the one end of the door panel 12.

When the moving member 40 is in the unlocked position, the blocking member 50 is disengaged from the one end of the door panel 12.

[0059] The side wall 11 is provided with a first groove 13 and a second groove 14. The moving part 40 comprises a first surface 41, a second surface 42, a third surface 43 and a fourth surface 44. The first groove 13 is provided with a first protrusion 1411 on the bottom wall, and the first surface 41 is provided with a second protrusion 411. The first protrusion 70 is in engagement with the second protrusion to limit the downward displacement of the moving part 40. The protrusion 70 is provided on the second surface 42, and the application does not limit the shape of the protrusion 70, which can be cylindrical, rectangular, etc. One end of the elastic part 61 is sleeved on the protrusion 70, and the protrusion 70 can limit the displacement of the elastic part 61 in the direction parallel to the second surface 42. The other end of the elastic part 61 can abut against the side wall 132 of the first groove. A containing space for containing the elastic part 61 can also be provided on the side wall 11, and the other end of the elastic part 61 extends into the containing space.

When the moving part 40 is in the unlocked position, the fourth surface 44 abuts against the side wall 142 of the second groove 14.

[0060] The first end 121 of the door plate 12 is the upper end, and the second end 122 is the lower end. The door plate 12 can be pivoted about an axis 20, and the axis 20 is located at the second end 122. The axis 20 and the second end 122 are located below the outlet 112.

[0061] The blocking piece 50 is the first surface 41 of the moving piece 40. When the moving piece 40 is in the locked position, the blocking piece 50 is located outside the first end 121 and in contact with the first end 121, and the door panel 12 is rotated clockwise. When the moving piece 40 is pushed upward by the trigger piece 204 of the base station 200 to move from the locked position to the unlocked position, the moving piece 40 drives the blocking piece 50 to move upward until the blocking piece 50 is out of contact with the first end 121.
