Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a base station and a cleaning system. BACKGROUND

[0002] As a cleaning device, a dust collector is mainly used for sucking dust, hair, debris and other sundries to keep the application environment clean. The dust collector can suck the sundries into a dust cup through a suction port under the action of suction force generated by a motor.

[0003] The base station is a matched device of the dust collector. After the dust collector completes work, the dust collector can be put back to the base station. On the one hand, the base station can be used for charging the dust collector, and on the other hand, the base station can collect dust in the dust cup of the dust collector, so as to free the user from manually cleaning the dust cup, which is conducive to simplifying the cleaning process and reducing the risk of secondary pollution.

[0004] In the dust collection process of the base station on the dust collector, the dust cup bottom cover is opened, and the sundries in the dust cup fall into the dust bag of the base station. In the related technology, the dust cup bottom cover is driven to open by a motor drive or a mechanical transmission. However, increasing the motor is easy to cause the internal structure of the base station to be complex and the cost to be high. By the mechanical transmission, it is easy to increase the resistance of the dust cup bottom cover to open, and there are easy to exist the phenomenon of jamming or failure. The reliability of opening and closing of the dust cup bottom cover is low. UTILITY MODEL CONTENT

[0005] The present application provides a base station and a cleaning system, which can solve the problem of low reliability of opening and closing of the dust cup bottom cover, which affects the dust collection effect.

[0006] In a first aspect, the present application provides a base station, comprising:

[0007] A base station body can be used to collect dust in a dust cup. The dust cup is provided with a cover body for opening or closing an opening of the dust cup. A dust collection air duct is arranged in the base station body. The opening of the dust cup corresponds to the dust collection air duct. The cover body is opened or closed to communicate or isolate the dust cup and the dust collection air duct;

[0008] A dust collection motor is arranged in the base station body. The dust collection motor can be used to generate airflow;

[0009] A driving structure is arranged on the outer wall of the dust collection air duct. The driving structure comprises a movable rod and a shell capable of accommodating at least part of the movable rod. The movable rod is used to drive the cover body to open or close. The movable rod can divide the internal space of the shell into a first chamber and a second chamber. One of the first chamber and the second chamber can enter the airflow generated by the dust collection motor, and the other can enter the airflow of the external environment;

[0010] When the dust collecting motor is started or stopped, the pressure difference between the first chamber and the second chamber is different, so that the movable rod is driven to move by air flow, and the cover is opened or closed.

[0011] The base station provided in the application can reasonably utilize the negative pressure environment generated by the dust collecting motor. When the dust collecting motor is started, the pressure difference between the base station body and the shell of the movable rod can be generated, so that the movable rod is driven to move by air flow, and the cover can be opened. When the dust collecting motor is stopped, the pressure difference between the base station body and the shell of the movable rod tends to be equal, so that the movable rod can be driven to reset by air flow, and the cover can be closed.

[0012] Therefore, by utilizing the negative pressure environment generated during the operation of the dust collecting motor as the power source for driving the movable rod to move, the cover can be opened or closed to open the dust cup, so that it is no longer necessary to add a motor and other complex structures, which is beneficial to reduce the possibility of structural complexity and cost increase caused by the addition of the motor. Moreover, it can also effectively reduce the possibility of the simple mechanical structure movement causing the jamming phenomenon, which is beneficial to improve the movement reliability of the movable rod and ensure the normal operation of the dust collecting work.

[0013] Specifically, when the cleaning body is not placed in the base station, the cover of the dust cup can be in a closed state to avoid the scattering of the sundries in the dust bag to the external environment. When the cleaning body is placed in the base station, the dust collecting motor is started to generate a negative pressure environment in the dust collecting air duct. At this time, on the one hand, the air pressure in the internal space of the dust cup is greater than the air pressure in the dust collecting air duct (for example, when the air pressure difference is greater than a first preset value), and the air flow in the internal space of the dust cup can drive the cover to move in the direction of the dust collecting air duct. On the other hand, since the movable rod is used to drive the cover to open or close, the power source of the movable rod comes from the pressure difference between the first chamber and the second chamber, and therefore, when the dust collecting motor is started, a negative pressure environment is generated in the dust collecting air duct. A large pressure difference (for example, when the pressure difference is greater than a second preset value) can be generated between the first chamber and the second chamber, so that the air flow can drive the movable rod to move away from the cover, and the movable rod will not hinder the opening of the cover. Therefore, by the action of the cover by the above two aspects, the cover can be opened. The sundries in the dust cup can enter the dust bag through the dust collecting air duct.

[0014] After the dust collecting motor is stopped, the air pressure in the dust collecting air duct can gradually tend to the air pressure of the external environment. At this time, on the one hand, the air pressure in the dust collecting air duct tends to the air pressure in the internal space of the dust cup, and the cover is no longer subjected to the action force blowing to the dust collecting air duct. On the other hand, the air pressures of the first chamber and the second chamber also tend to be equal, so that the movable rod can be reset. For example, the reset direction of the movable rod can be to push the cover to move in the direction of the dust cup to close the cover.

[0015] According to an embodiment of the present application, the second chamber is located on the side of the first chamber away from the dust collecting air duct, the first chamber is in communication with the external environment, and the second chamber is in communication with the airflow generated by the dust collecting motor;

[0016] When the dust collecting motor is started, the air pressure in the first chamber is greater than the air pressure in the second chamber, so that the movable rod is away from the cover body, and the cover body is in an open state.

[0017] When the dust collecting motor is stopped, the air pressure in the second chamber is equal to the air pressure in the first chamber, so that the movable rod moves towards the cover body, and the cover body is in a closed state.

[0018] In the embodiment of the present application, since the second chamber is in communication with the airflow generated by the dust collecting motor, when the dust collecting motor is started, the suction force generated by the dust collecting motor can generate a negative pressure environment in the second chamber. Since the first chamber is in communication with the external environment, the air pressure in the first chamber is greater than the air pressure in the second chamber, so that the airflow can drive the movable rod to move towards the second chamber. Since the second chamber is located on the side of the first chamber away from the dust collecting air duct, when the movable rod moves towards the second chamber, the movable rod can gradually move away from the cover body of the dust cup. The movable rod can release the force applied to the cover body to close the opening of the dust cup.

[0019] When the dust collecting motor is stopped, the dust collecting motor no longer generates a negative pressure environment. The air pressure in the second chamber can gradually recover to be close to the air pressure of the external environment. The air pressure in the second chamber can be close to the air pressure in the first chamber, so that the movable rod can move towards the first chamber under the action of the air pressure to reset. The movable rod can push the cover body to close the opening of the dust cup.

[0020] According to an embodiment of the present application, the dust cup is in communication with the external environment, the opening of the dust cup faces downward, and the dust collecting motor is located at the bottom of the base body.

[0021] When the dust collecting motor is started, the air pressure in the dust cup is greater than the air pressure at the dust collecting motor, so as to open the cover body, and the dust cup is in communication with the dust collecting air duct.

[0022] In the embodiment of the present application, the internal space of the dust cup can be in communication with the external environment. When the dust collecting motor is started, a negative pressure environment is also generated in the dust collecting air duct located below the dust cup. The air pressure in the dust cup is greater than the air pressure in the dust collecting air duct, so that the cover body can be driven to move towards the dust collecting air duct under the action of the air pressure. At this time, since the movable rod is away from the cover body, the cover body can be in an open state under the action of the airflow, and the dust in the dust cup can pass downward through the dust collecting air duct and enter the dust bag.

[0023] According to one embodiment of the present application, the driving structure further comprises a reset member, and the reset member is located in the second chamber;

[0024] When the dust collecting motor is started, the movable rod is away from the cover, so that the reset member is deformed;

[0025] When the dust collecting motor is stopped, the reset member can drive the movable rod to extend from the inner wall of the dust collecting channel, and the movable rod pushes the cover to close the dust cup.

[0026] In the embodiment of the present application, when the dust collecting motor is started, the movable rod can move towards the second chamber under the action of air pressure. Since the reset member is located in the second chamber, the continuous action of the movable rod towards the second chamber can cause the reset member to be compressed and deformed. When the dust collecting motor is stopped, the air pressure in the first chamber and the second chamber can tend to be equal. The movable rod is no longer subjected to the action force of air pressure pushing it towards the second chamber. The reset member can release elastic potential energy to facilitate the movement of the movable rod towards the first chamber and reset. At this time, the movable rod can push the cover to close the dust cup.

[0027] According to one embodiment of the present application, along the movement direction of the movable rod, the bottom wall of the shell is provided with a first guide column, the movable rod is provided with a second guide column, one of the first guide column and the second guide column is sleeved on the outer wall of the other, and the first guide column and the second guide column are slidably connected;

[0028] The reset member can be sleeved on the outer wall of the first guide column or the second guide column.

[0029] In the embodiment of the present application, through the cooperation of the first guide column and the second guide column, the movable rod can be kept moving along the axis direction of the first guide column, so as to reduce the possibility that the movement path of the movable rod deviates in the process of pushing or releasing the cover, thereby affecting the opening or closing of the cover.

[0030] According to one embodiment of the present application, a limiting part is arranged in the shell, the limiting part is located in the first chamber, and when the movable rod is connected with the limiting part, the end of the movable rod can abut against the cover to keep the cover closed.

[0031] In the embodiment of the present application, the limiting part can be used to constrain the maximum movement path of the movable rod in the direction of the first chamber, so as to reduce the possibility that the cover is deformed due to the continuous closing action of the movable rod on the cover when the cover is in the closed state. In addition, the excessive action of the movable rod on the cover can also easily cause a larger pressure difference to be generated between the second chamber and the first chamber to drive the movable rod away from the cover when the cover needs to be opened, which can easily cause energy loss.

[0032] According to an embodiment of the present application, the shell is provided with a first air inlet communicating with the first chamber, and the first air inlet communicates with the external environment.

[0033] In the embodiment of the present application, the first air inlet can be used to communicate the first chamber with the external environment. When the dust collecting motor is started or stopped, the first chamber can be kept in a state of communication with the external environment.

[0034] According to an embodiment of the present application, the sidewall of the dust collecting air duct is provided with a through hole for the movable rod to pass through, the movable rod is in clearance fit with the through hole, and the first air inlet is close to the through hole.

[0035] In the embodiment of the present application, the end of the movable rod used to push the cover body can pass through the through hole. The movable rod and the through hole can be in clearance fit, so that the movable rod can smoothly pass through the through hole. In addition, when the dust collecting motor is started, the dust collecting air duct is in a negative pressure environment. Since the first chamber communicates with the external environment, the air pressure in the first chamber can be greater than the air pressure in the dust collecting air duct. The airflow in the first chamber can be blown to the dust collecting air duct through the clearance between the movable rod and the through hole, so that the dust in the dust collecting air duct can not block the clearance between the movable rod and the through hole during the dust collecting process, or the dust can not enter the shell through the through hole, which can avoid affecting the flexibility of the movable rod, and even avoid causing the movable rod to be stuck.

[0036] According to an embodiment of the present application, the base station comprises an airflow pipeline, one end of the airflow pipeline communicates with the dust collecting motor, the other end of the airflow pipeline communicates with the second chamber, and the airflow generated by the dust collecting motor enters the second chamber through the airflow pipeline.

[0037] In the embodiment of the present application, the dust collecting motor and the second chamber of the shell can be communicated through the airflow pipeline. When the dust collecting motor is started, the dust collecting motor generates suction force to generate negative pressure in the airflow pipeline, and the second chamber is in a negative pressure environment through the airflow pipeline.

[0038] According to an embodiment of the present application, the movable rod has an included angle with the vertical direction, and the driving structure is obliquely arranged on the sidewall of the dust collecting air duct.

[0039] In the embodiment of the present application, the driving structure is obliquely arranged on the sidewall of the dust collecting air duct, so that the driving structure can not easily occupy the space of the dust collecting air duct, so that the dust collecting air duct has sufficient dust collecting space. In addition, the movable rod has an oblique included angle. The movable rod can respectively exert vertical and horizontal component forces on the cover body, so that the cover body can be closed by a smaller force.

[0040] In a second aspect, the present application provides a cleaning system, which comprises:

[0041] The cleaning main body is provided with a dust cup capable of containing dust, and the dust cup is provided with a cover body movably connected to an opening of the dust cup to open or close the opening.

[0042] The base station of any of the above embodiments, the opening of the dust cup corresponds to the dust collection air duct of the base station, and the cover body is opened or closed to communicate or isolate the dust cup and the dust collection air duct.

[0043] In the embodiments of the present application, the negative pressure environment generated by the dust collection motor can be reasonably utilized to drive the movable rod to open or close the cover body through the pressure difference between the external environment and the negative pressure environment, which has simple structure and high reliability.

[0044] According to an embodiment of the present application, the cover body is rotatably connected to the dust cup through a rotating shaft, and one end of the cover body away from the rotating shaft is magnetically connected to the cover body.

[0045] In the embodiments of the present application, one end of the cover body away from the rotating shaft can close the opening of the dust cup through magnetic attraction. For example, a magnet can be arranged on one of the cover body and the opening of the dust cup. During the process of the movable rod pushing the cover body to move in the direction of the opening, when the cover body approaches the opening of the dust cup, the cover body can be connected to the dust cup under the action of magnetic attraction to close the opening of the dust cup.

[0046] According to an embodiment of the present application, one end of the rotating shaft is arranged near the end of the movable rod.

[0047] In the embodiments of the present application, the end of the movable rod for pushing the cover body to close can be arranged near the rotating shaft, so that the cover body can be closed or opened through a small movement stroke of the movable rod.

[0048] The base station provided by the present application has the following advantages: by reasonably utilizing the negative pressure environment generated by the dust collection motor and combining with the driving structure, the cover body of the dust cup can be opened or closed under the action of airflow. The overall structure is simple, the movement reliability of the driving structure is high, and the phenomenon of jamming is less likely to occur. Moreover, the negative pressure environment generated by the dust collection motor is used as the power source for driving the movable rod to move, and there is no need to additionally increase a motor or other complex structure, which is conducive to reducing the possibility of increasing the structure and cost caused by the motor.

[0049] In addition to the technical problems solved by the above-described embodiments of the present application, the technical features constituting the technical solutions, and the beneficial effects brought by these technical features, the other technical problems solved by the base station and the cleaning system provided by the embodiments of the present application, the other technical features included in the technical solutions, and the beneficial effects brought by these technical features will be further described in detail in the specific embodiments.

[0069] The specific embodiments of the application will now be described in detail with reference to the following figures. The following description, in conjunction with the figures, is intended to explain the best ways known to the inventors to implement the application at the time of filing. However, the application, as described below, can be carried out in many ways and using a variety of structures and techniques. DETAILED DESCRIPTION

[0070] The exemplary embodiments will be described in detail with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers refer to like elements throughout the several drawings. The following description is not to be read to imply that any particular feature, material, or process disclosed herein is essential to the application. The application illustratively described herein suitably protects the right to exclude only those functions of the application that are particularly claimed in the claims.

[0071] The dust collector and the base station can jointly constitute an efficient cleaning system to provide users with a convenient and efficient cleaning experience. The working principle of the dust collector is to use the suction force generated by the motor to suck dust, hair, debris and other sundries on the surface of the ground, furniture, curtains, etc. into the dust cup through the suction port. The base station, as a supporting device of the dust collector, is used to collect, store and process dust and other sundries generated by the dust collector. The base station can use strong suction force to suck dust and sundries in the dust cup of the dust collector into the storage box or dust bag in the base station, so as to free the user from manually cleaning the dust cup, which is conducive to simplifying the cleaning process and reducing the risk of secondary pollution.

[0072] During the dust collection process of the base station on the dust collector, the dust cup bottom cover is opened, and the sundries in the dust cup can fall into the dust bag of the base station. In the related art, the dust cup bottom cover is driven to open by a motor drive or a mechanical transmission. However, increasing the motor is likely to cause the internal structure of the base station to be complex and the cost to be high. By the mechanical transmission, the resistance of the dust cup bottom cover to open is likely to be increased, and the phenomenon of being stuck or failing to work is likely to exist. The reliability of the opening and closing of the dust cup bottom cover is low, which is likely to cause the problem of affecting the dust collection effect.

[0073] Based on the above technical problems, the applicant improves the structure of the existing base station. In the embodiment of the application, the negative pressure environment generated by the dust collecting motor can be reasonably utilized. When the dust collecting motor is started, a pressure difference can be generated in the base body and the shell moving with the movable rod, so as to drive the movable rod to move under the action of air flow, so that the cover body can be opened. When the dust collecting motor stops, the pressure difference in the base body and the shell moving with the movable rod decreases to tend to be equal, so that the movable rod can be driven to reset under the action of air flow, so that the cover body can be closed.

[0074] Therefore, by utilizing the negative pressure environment generated during the operation of the dust collecting motor as a power source for driving the movable rod to move, the cover body can open or close the opening of the dust cup, so that it is no longer necessary to add a complex structure such as a motor, which is beneficial to reduce the possibility of increasing the structure complexity and cost caused by adding the motor. Moreover, it can also effectively reduce the possibility of causing the phenomenon of being easily stuck caused by simply using mechanical structure movement, which is beneficial to improve the movement reliability of the movable rod and ensure the normal operation of the dust collecting work.

[0075] The base station 100 and the cleaning system 10 provided by the application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0076] Referring to Figures 1 to 4 It is to be noted that, Figure 1 The partial structure diagram of the cleaning system 10 is schematically shown. It includes the partial structure of the base body 110 and the partial structure of the cleaning body 200.

[0077] The base body 110 can be used to provide charging service for the cleaning body 200 and to maintain and clean the cleaning body 200 when necessary. The cleaning body 200 can suck dust, hair, debris and other sundries on the surface of the ground, furniture, curtains and the like into the dust cup 220.

[0078] The cleaning body 200 can include a main machine 210, a dust cup 220 and a cleaning brush. The cleaning body 200 can also be provided with a handheld part 230. A user can operate the cleaning body 200 through the handheld part 230 to perform cleaning. When the cleaning body 200 is placed on the base station 100, the dust cup 220 can be connected with the dust collecting air duct 111 in the base body 110. The base body 110 can be used to collect dust in the dust cup 220.

[0079] The dust cup 220 is provided with a cover body 221. The cover body 221 is used to open or close the opening of the dust cup 220. The base body 110 is provided with a dust collecting air duct 111. The opening of the dust cup 220 corresponds to the dust collecting air duct 111, and the cover body 221 is opened or closed to communicate or isolate the dust cup 220 and the dust collecting air duct 111.

[0080] It is easy to understand that the dust collection air duct 111 can correspond to the dust bag 300. When the cover body 221 is in the open state, the sundries in the dust cup 220 can enter the dust bag 300 through the dust collection air duct 111.

[0081] In some examples, the dust bag 300 can support the dust collection requirement for several weeks or even months, so the user does not need to frequently replace the dust bag 300.

[0082] The dust collection motor 120 is located in the base station body 110. The dust collection motor 120 can be used to generate an air flow to open the cover body 221. The dust collection motor 120 generates an air flow to form a negative pressure environment in the corresponding environment, so that when the cover body 221 is in the open state, on the one hand, the sundries in the dust cup 220 can fall into the dust bag 300 under the action of its own gravity through the dust collection air duct 111, and on the other hand, the dust collection motor 120 starts to generate a suction force to make the dust bag 300 and the dust collection air duct 111 in a negative pressure environment, thereby a pressure difference is generated between the dust cup 220 and the dust collection air duct 111, and under the action of the air flow, the sundries in the dust cup 220 can enter the dust bag 300, which is conducive to improving the dust collection efficiency and effect of the dust cup 220.

[0083] The driving structure 130 is arranged on the outer wall of the dust collection air duct 111. The driving structure 130 includes a movable rod 131 and a shell 132 capable of accommodating at least part of the movable rod 131. The movable rod 131 can be used to drive the cover body 221 to open or close. Specifically, one end of the movable rod 131 can be used to abut against the cover body 221. The movement of the movable rod 131 towards the cover body 221 can keep the cover body 221 in the closed state. The movement of the movable rod 131 away from the cover body 221 can release the closing force of the movable rod 131 on the cover body 221, so that the cover body 221 can be opened.

[0084] The movable rod 131 can divide the internal space of the shell 132 into a first chamber 132a and a second chamber 132b. One of the first chamber 132a and the second chamber 132b can enter the air flow generated by the dust collection motor 120, and the other can enter the air flow of the external environment. When the dust collection motor 120 is started or stopped, the pressure difference between the first chamber 132a and the second chamber 132b is different, so as to drive the movable rod 131 to move by the air flow, and the movable rod 131 opens or closes the cover body 221.

[0085] In the embodiments of the present application, referring to Figure 3 and Figure 4As shown, when the cleaning main body 200 is not placed in the base station 100, the cover 221 of the dust cup 220 can be in a closed state to avoid the sundries in the dust bag 300 from being scattered to the external environment. When the cleaning main body 200 is placed in the base station 100, the dust collecting motor 120 is started to generate a negative pressure environment in the dust collecting air duct 111. At this time, on the one hand, the air pressure in the internal space of the dust cup 220 is greater than the air pressure in the dust collecting air duct 111 (for example, when the air pressure difference is greater than a first preset value), and the airflow in the internal space of the dust cup 220 can drive the cover 221 to move in the direction of the dust collecting air duct 111. On the other hand, since the movable rod 131 is used to drive the cover 221 to open or close, the power source of the movable rod 131 comes from the pressure difference between the first chamber 132a and the second chamber 132b. Therefore, when the dust collecting motor 120 is started, a negative pressure environment is generated in the dust collecting air duct 111. A large pressure difference (for example, when the pressure difference is greater than a second preset value) can be generated between the first chamber 132a and the second chamber 132b, so that the airflow can drive the movable rod 131 to move away from the cover 221, and the movable rod 131 will not hinder the opening of the cover 221. Therefore, through the above two aspects of the force acting on the cover 221, the cover 221 can be opened. The sundries in the dust cup 220 can enter the dust bag 300 through the dust collecting air duct 111.

[0086] After the dust collecting motor 120 is stopped, the air pressure in the dust collecting air duct 111 can gradually tend to the air pressure of the external environment. At this time, on the one hand, the air pressure in the dust collecting air duct 111 tends to the air pressure in the internal space of the dust cup 220, and the cover 221 is no longer subjected to the force blowing to the dust collecting air duct 111. On the other hand, the air pressures of the first chamber 132a and the second chamber 132b also tend to be equal, so that the movable rod 131 can be reset. For example, the reset direction of the movable rod 131 can be to push the cover 221 to move in the direction of the dust cup 220 to close the cover 221.

[0087] In some examples, when the dust cup 220 is placed in the base station main body 110, the dust collecting motor 120 can be started. At this time, the cover 221 can be automatically opened under the action of the airflow, and the dust collecting work can be performed. When the dust collecting is completed, the dust collecting motor 120 can be stopped. At this time, the cover 221 can be closed under the action of the airflow, so that when the dust cup 220 is taken out, the cover 221 can remain in a closed state.

[0088] In some examples, when the cleaning main body 200 is placed in the base station 100, the starting time of the dust collecting motor 120 can be set according to the capacity of the dust cup 220, the power of the dust collecting motor 120 and other factors, so that the automatic dust collecting of the dust cup 220 can be completed within the time. After the automatic dust collecting is completed, the dust collecting motor 120 can be automatically stopped, so that the automatic dust collecting of the base station 100 can be realized, which is beneficial to improve the automation and intelligent experience of the cleaning system 10.

[0089] It should be noted that the first chamber 132a can be in communication with the airflow generated by the dust collecting motor 120. Alternatively, the second chamber 132b can be in communication with the airflow generated by the dust collecting motor 120, which is not limited in the embodiments of the present application.

[0090] In some examples, the movable rod 131 can include a partition 1312. The partition 1312 can separate the shell 132 into the first chamber 132a and the second chamber 132b. The partition 1312 can be slidingly connected to the inner wall of the shell 132. The end of the movable rod 131 for driving the cover 221 to move can be located in the first chamber 132a.

[0091] In some examples, the shell 132 can be detachably connected to the outer wall of the dust collecting air duct 111. For example, the shell 132 can be fixed to the dust collecting air duct 111 by a locking member, but is not limited thereto.

[0092] In some examples, a sealing ring can be arranged between the partition 1312 and the inner wall of the shell 132. The sealing ring can avoid the airflow of the first chamber 132a and the second chamber 132b from being in communication.

[0093] In some implementable manners, referring to FIGS. 1, 2 and 3, the second chamber 132b of the embodiments of the present application can be located on the side of the first chamber 132a away from the dust collecting air duct 111. The first chamber 132a is in communication with the external environment. The second chamber 132b is in communication with the airflow generated by the dust collecting motor 120. Figure 3 Figure 4 When the dust collecting motor 120 is started, the air pressure of the first chamber 132a is greater than that of the second chamber 132b, so that the movable rod 131 moves away from the cover 221, and the cover 221 is in an open state. When the dust collecting motor 120 is stopped, the air pressure of the second chamber 132b is equal to that of the first chamber 132a, so that the movable rod 131 moves towards the cover 221, and the cover 221 is in a closed state.

[0094] When the dust collecting motor 120 is started, the air pressure of the first chamber 132a is greater than that of the second chamber 132b, so that the movable rod 131 moves away from the cover 221, and the cover 221 is in an open state. When the dust collecting motor 120 is stopped, the air pressure of the second chamber 132b is equal to that of the first chamber 132a, so that the movable rod 131 moves towards the cover 221, and the cover 221 is in a closed state.

[0095] ​In the embodiment of the present application, since the second chamber 132b is in communication with the airflow generated by the dust collecting motor 120, when the dust collecting motor 120 is started, the suction force generated by the dust collecting motor 120 can cause the second chamber 132b to generate a negative pressure environment. Since the first chamber 132a is in communication with the external environment, the air pressure in the first chamber 132a is greater than the air pressure in the second chamber 132b, so that the airflow can drive the movable rod 131 to move in the direction of the second chamber 132b. Since the second chamber 132b is located on the side of the first chamber 132a away from the dust collecting air duct 111, when the movable rod 131 moves in the direction of the second chamber 132b, the movable rod 131 can gradually move away from the cover 221 of the dust cup 220. The movable rod 131 can release the force exerted on the cover 221 to close the opening of the dust cup 220.

[0096] When the dust collecting motor 120 stops, the dust collecting motor 120 no longer generates a negative pressure environment. The air pressure in the second chamber 132b can gradually return to the same as the air pressure of the external environment. The air pressure in the second chamber 132b can be close to the air pressure in the first chamber 132a, so that the movable rod 131 can move in the direction of the first chamber 132a under the action of the air pressure to reset. The movable rod 131 can push the cover 221 to close the opening of the dust cup 220.

[0097] In some implementable manners, referring to Figure 4 the dust cup 220 of the embodiment of the present application is in communication with the external environment, and the opening of the dust cup 220 faces downward. The dust collecting motor 120 is located at the bottom of the base station main body 110. When the dust collecting motor 120 is started, the air pressure of the dust cup 220 is greater than the air pressure at the dust collecting motor 120, so as to open the cover 221. The dust cup 220 is in communication with the dust collecting air duct 111.

[0098] In the embodiment of the present application, the internal space of the dust cup 220 can be in communication with the external environment. When the dust collecting motor 120 is started, a negative pressure environment is also generated in the dust collecting air duct 111 located below the dust cup 220. The air pressure in the dust cup 220 is greater than the air pressure in the dust collecting air duct 111, so as to drive the cover 221 to move in the direction of the dust collecting air duct 111 under the action of the air pressure. At this time, since the movable rod 131 has moved away from the cover 221, the cover 221 can be in an open state under the action of the airflow, and the dust in the dust cup 220 can pass downward through the dust collecting air duct 111 into the dust bag 300.

[0099] In some implementable manners, referring to Figure 3 and Figure 4As shown, the driving structure 130 of the embodiment of the present application can further include a reset member 133. The reset member 133 can be located in the second chamber 132b. When the dust collection motor 120 is started, the movable rod 131 moves away from the cover 221, so that the reset member 133 is deformed. When the dust collection motor 120 is stopped, the reset member 133 can drive the movable rod 131 to extend from the inner wall of the dust collection passage, and the movable rod 131 pushes the cover 221 to close the dust cup 220.

[0100] In the embodiment of the present application, when the dust collection motor 120 is started, the movable rod 131 can move in the direction of the second chamber 132b under the action of air pressure. Since the reset member 133 is located in the second chamber 132b, the continuous action of the movable rod 131 in the direction of the second chamber 132b can cause the reset member 133 to be compressed and deformed. When the dust collection motor 120 is stopped, the air pressure in the first chamber 132a and the second chamber 132b can tend to be equal. The movable rod 131 is no longer subjected to the force pushing it in the direction of the second chamber 132b. The reset member 133 can release the elastic potential energy to drive the movable rod 131 to move in the direction of the first chamber 132a and reset. At this time, the movable rod 131 can push the cover 221 to close the dust cup 220.

[0101] In some examples, the reset member 133 can be, but is not limited to, a spring, a rubber member, etc.

[0102] In some implementable manners, referring to Figures 3 to 6 As shown, along the movement direction of the movable rod 131, the bottom wall of the shell 132 can be provided with a first guide column 1321. The movable rod 131 can be provided with a second guide column 1311. One of the first guide column 1321 and the second guide column 1311 is sleeved on the outer wall of the other. The first guide column 1321 and the second guide column 1311 are slidably connected. The reset member 133 can be sleeved on the outside of the first guide column 1321 or the second guide column 1311.

[0103] In the embodiment of the present application, through the cooperation of the first guide column 1321 and the second guide column 1311, the movable rod 131 can be kept moving along the axis direction of the first guide column 1321, so as to reduce the possibility that the movement path of the movable rod 131 deviates in the process of pushing or releasing the cover 221, and affecting the opening or closing of the cover 221.

[0104] In some examples, the second guide column 1311 can be arranged on one side of the partition portion 1312 facing the second chamber 132b. The second guide column 1311 is located in the second chamber 132b.

[0105] In some examples, referring to Figure 6As shown, the second guide column 1311 can be sleeved on the outer wall of the first guide column 1321. Alternatively, the first guide column 1321 can be sleeved on the outer wall of the second guide column 1311, which is not limited in the embodiments of the present application.

[0106] For example, when the movable rod 131 causes the cover 221 to close, part of the reset member 133 can be sleeved on the outer wall of the second guide column 1311. Part of the reset member 133 can be sleeved on the outer wall of the first guide column 1321.

[0107] In some examples, referring to Figure 5 As shown, the movable rod 131 can include two second guide columns 1311 arranged side by side. Correspondingly, the bottom wall of the shell 132 can also be provided with first guide columns 1321 respectively matched with the two second guide columns 1311. By matching the two second guide columns 1311 with the two first guide columns 1321 respectively, the reliability of the movable rod 131 driving the cover 221 to open or close can be improved.

[0108] In some examples, when the reset member 133 is a spring, the spring force of the reset member 133 needs to meet the following conditions:

[0109] The spring force of the reset member 133 at the maximum compression position is less than the negative pressure force in the shell 132, so that when the second chamber 132b is in a negative pressure environment, the spring force of the reset member 133 will not make the movable rod 131 difficult to move towards the second chamber 132b, thereby ensuring that the movable rod 131 moves away from the cover 221, and then the cover 221 is opened.

[0110] In addition, the spring force of the reset member 133 at the maximum compression position is greater than the resistance when the cover 221 is closed, so that when the reset member 133 releases the elastic potential energy, the reset member 133 can overcome the force of the elastic potential energy to move towards the cover 221 to close the cover 221.

[0111] In some implementable ways, referring to Figure 3 and Figure 4 As shown, the shell 132 of the present application can be provided with a limiting portion 1322. The limiting portion 1322 can be located in the first chamber 132a. When the movable rod 131 is connected with the limiting portion 1322, the end of the movable rod 131 can abut against the cover 221 to keep it closed.

[0112] In this embodiment, the limiting part 1322 can be used to constrain the maximum movement path of the movable rod 131 towards the first chamber 132a, thereby reducing the possibility that the movable rod 131 will continue to exert a closing force on the cover 221 when the cover 221 is in the closed state, which could lead to deformation of the cover 221. Furthermore, the excessive force exerted by the movable rod 131 on the cover 221 can easily lead to a greater pressure difference between the second chamber 132b and the first chamber 132a when the cover 221 needs to be opened, in order to drive the movable rod 131 away from the cover 221, potentially resulting in energy loss.

[0113] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, the housing 132 is provided with a first air inlet 132c that communicates with the first chamber 132a. The first air inlet 132c is connected to the external environment.

[0114] In this embodiment, the first air inlet 132c can be used to connect the first chamber 132a to the external environment. When the dust collection motor 120 starts or stops, the first chamber 132a can remain in a state of connection with the external environment.

[0115] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, the side wall of the dust collection duct 111 in this embodiment of the application may be provided with a through hole 111a through which the movable rod 131 can pass. The movable rod 131 is clearance-fitted with the through hole 111a. The first air inlet 132c may be located close to the through hole 111a.

[0116] In this embodiment, the end of the movable rod 131 used to push the cover 221 can pass through the through hole 111a. The movable rod 131 and the through hole 111a can be clearance-fitted to allow the movable rod 131 to pass smoothly through the through hole 111a. Furthermore, when the dust collection motor 120 starts, the dust collection duct 111 is in a negative pressure environment. Since the first chamber 132a is connected to the external environment, the air pressure inside the first chamber 132a can be greater than the air pressure inside the dust collection duct 111. The airflow inside the first chamber 132a can be blown from the first chamber 132a through the gap between the movable rod 131 and the through hole 111a towards the dust collection duct 111, thereby preventing dust in the dust collection duct 111 from clogging the gap between the movable rod 131 and the through hole 111a during the dust collection process, or preventing dust from entering the housing 132 through the through hole 111a, which would affect the flexibility of the movable rod 131 or even cause the movable rod 131 to jam.

[0117] See also some of the possible implementation methods. Figure 2As shown, the base station 100 can include an air flow pipe 140. One end of the air flow pipe 140 is in communication with the dust collecting motor 120. The other end of the air flow pipe 140 can be in communication with the second chamber 132b. The air flow generated by the dust collecting motor 120 enters the second chamber 132b through the air flow pipe 140.

[0118] In the embodiments of the present application, the dust collecting motor 120 and the second chamber 132b of the housing 132 can be in communication through the air flow pipe 140. When the dust collecting motor 120 is started, the dust collecting motor 120 generates suction to generate negative pressure in the air flow pipe 140, and the second chamber 132b is in a negative pressure environment through the air flow pipe 140.

[0119] In some examples, the second chamber 132b can be provided with a second air inlet 132d. The second air inlet 132d can be used to communicate with the air flow pipe 140.

[0120] In some realizable ways, referring to Figures 2 to 4 As shown, the movable rod 131 has an angle with the vertical direction. The driving structure 130 is obliquely arranged on the side wall of the dust collecting air duct 111.

[0121] In the embodiments of the present application, the driving structure 130 is obliquely arranged on the side wall of the dust collecting air duct 111, so that the driving structure 130 can not easily occupy the space of the dust collecting air duct 111, so that the dust collecting air duct 111 has sufficient dust collecting space. In addition, the movable rod 131 has an oblique angle. The movable rod 131 can respectively exert vertical and horizontal directional component forces on the cover 221, so that the cover 221 can be closed by a smaller force.

[0122] The embodiments of the present application also provide a cleaning system 10, referring to Figure 1 As shown, the cleaning system 10 can include a cleaning main body 200 and the base station 100 in any of the above embodiments.

[0123] The cleaning main body 200 is provided with a dust cup 220 capable of accommodating dust. The dust cup 220 is provided with a cover 221. The cover 221 can be movably connected to the opening of the dust cup 220 to open or close the opening. The opening of the dust cup 220 corresponds to the dust collecting air duct 111 of the base station 100. The cover 221 is opened or closed to communicate or isolate the dust cup 220 and the dust collecting air duct 111.

[0124] In the embodiments of the present application, the negative pressure environment generated by the dust collecting motor 120 can be reasonably utilized to drive the movable rod 131 to open or close the cover 221 through the pressure difference between the external environment and the negative pressure environment, which has simple structure and high reliability.

[0125] In some possible implementation manners, the cover 221 is rotatably connected to the dust cup 220 through the rotating shaft 222, and one end of the cover 221 away from the rotating shaft 222 is magnetically connected to the cover 221.

[0126] In the embodiment of the present application, the one end of the cover 221 away from the rotating shaft 222 can close the opening of the dust cup 220 through magnetic attraction. For example, one of the cover 221 and the opening of the dust cup 220 can be provided with a magnet. During the process that the movable rod 131 pushes the cover 221 to move in the direction of the opening, when the cover 221 approaches the opening of the dust cup 220, the cover 221 can be connected to the dust cup 220 to close the opening of the dust cup 220 under the action of magnetic attraction.

[0127] It should be noted that when the dust collecting motor 120 is started, the movable rod 131 can move away from the cover 221 to cancel the abutting force on the cover 221. At this time, the dust collecting air duct 111 is in a negative pressure environment. The internal space of the dust cup 220 is in communication with the external environment. Therefore, under the action of airflow, the magnetic attraction between the cover 221 and the dust cup 220 can be overcome to make the cover 221 separate from the dust cup 220. The cover 221 can open the opening of the dust cup 220 under the action of its own gravity.

[0128] In some possible implementation manners, the end of the movable rod 131 close to the end of the cover 221 provided with the rotating shaft 222.

[0129] In the embodiment of the present application, the end of the movable rod 131 for pushing the cover 221 to close can be close to the rotating shaft 222, so that the cover 221 can be closed or opened through a smaller movement stroke of the movable rod 131.

[0130] It should be noted that the values and value ranges involved in the present application are approximate values, and there can be a certain range of errors due to the influence of the manufacturing process, which can be considered negligible by those skilled in the art.
