Description

TECHNICAL FIELD

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

[0002] Cleaning is usually a daily affair that people need to face, and directly affects the quality of people's daily life. People generally use various cleaning devices to clean dust accumulation areas such as the ground, for example: using a vacuum cleaner, a robot vacuum cleaner and other cleaning devices to remove dust, debris and other garbage from the dust accumulation area, and to collect and store the garbage. However, in the related art, when the garbage stored in the cleaning device is discharged, the dust cup used to store the garbage on the cleaning device needs to be removed, and then installed on the cleaning device after the garbage in the dust cup is poured out, which is cumbersome to operate. SUMMARY

[0003] The embodiments of the present application provide a cleaning device and a cleaning system, which are used to solve the problem that in the related art, when the garbage in the cleaning device is removed, the dust cup for storing the garbage needs to be removed, and then installed on the cleaning device after the garbage in the dust cup is poured out, which is cumbersome to operate.

[0004] The embodiments of the present application provide a cleaning device, which has a dust collection mode and a dust discharge mode, and the cleaning device is used in cooperation with a base station in the dust discharge mode. The cleaning device comprises:

[0005] A shell assembly is formed with a first dust collection cavity, a dust collection port, an air outlet, a pulse port and a dust discharge port in communication with the first dust collection cavity.

[0006] A filter is arranged in the first dust collection cavity, and the filter has a first surface and a second surface opposite to each other. The dust collection port and the dust discharge port are located on one side of the first surface, and the pulse port and the air outlet are located on one side of the second surface.

[0007] A negative pressure generating component, in the dust collection mode, the air outlet is opened and in communication with the negative pressure generating component, and in the dust collection mode, the dust collection port is opened. In the dust discharge mode, the negative pressure generating component is in communication with the second dust collection cavity of the base station, and in the dust discharge mode, the pulse port is opened and closed in a pulse form, and in the dust discharge mode, the dust discharge port is opened.

[0008] The cleaning device provided in the embodiments of the present application can suck dust and other garbage into the cleaning device through the dust suction port under the action of the negative pressure generating component in the dust suction mode, and part or all of the garbage entering the cleaning device can fall into the first dust collecting chamber under the blockage of the filter. The negative pressure generating component can bring the garbage in the first dust collecting chamber into the second dust collecting chamber of the base station to realize the discharge of the garbage in the cleaning device in the dust discharge mode. Compared with the related art in which the first dust collecting chamber of the cleaning device is removed and the garbage in the first dust collecting chamber is discharged, the dust discharge mode of the present application can reduce the manual operation process and improve the user experience. The dust suction mode and the dust discharge mode of the present application share the same negative pressure generating component, which can reduce the manufacturing cost and the weight of the cleaning system compared with the negative pressure generating components arranged on the cleaning device and the base station respectively. The pulse port is opened in the form of pulse, and a large amount of airflow will enter the first dust collecting chamber at the moment when the pulse port is opened. The large amount of airflow generated at the moment can more easily bring the dust in the first dust collecting chamber into the second dust collecting chamber, so that the dust discharge requirement from the first dust collecting chamber to the second dust collecting chamber can be met even by using a low-power negative pressure generating component. The low-power negative pressure generating component has a smaller power consumption, which can reduce the use cost.

[0009] In the dust discharge mode, the large amount of airflow entering through the pulse port will move from the second surface of the filter towards the first surface when the pulse port is opened, which has a large impact on the filter. The flow direction of the airflow is opposite to that in the dust suction mode, i.e., from the first surface of the filter towards the second surface. The garbage adhered to the filter in the dust suction mode can be washed away, so as to avoid the blockage of the filter. The pulse port of the present application is different from the dust suction port, the air outlet and the dust discharge port, and the opening and closing control is relatively independent.

DETAILED DESCRIPTION

[0050] In order to make the objects, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application with reference to the accompanying drawings.

[0051] The following description refers to the accompanying drawings. In the drawings, like reference numbers indicate the same or similar elements, unless the context dictates otherwise. The following examples are not representative of all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as described in the appended claims.

[0052] Reference should be made to Figure 1 The cleaning system 10 provided by the embodiments of the present application includes a cleaning device 100 and a base station 200. The cleaning device 100 can be used to clean dust accumulation areas such as floors, sofa surfaces, and seat surfaces, and remove dust and other garbage on the dust accumulation areas. Specifically, the cleaning device 100 can suck and store the garbage on the dust accumulation areas, so as to centrally process the garbage. The cleaning device 100 can be a vacuum cleaner, a cleaning robot, or the like, and the embodiments of the present application do not limit this. The base station 200 can be connected with the cleaning device 100, and is used to charge the cleaning device 100 and / or suck and clean the garbage stored in the cleaning device 100.

[0053] Optionally, the cleaning device 100 has a dust suction mode and a dust discharge mode. In the dust suction mode, the cleaning device 100 can be used to collect garbage in the dust accumulation area into the first dust collecting cavity 111 inside the cleaning device 100. In the dust discharge mode, the cleaning device 100 is connected with the base station 200, and is used to discharge the garbage in the first dust collecting cavity 111 to the second dust collecting cavity 210 of the base station 200. Compared with the related art, the garbage containing dust cup is removed from the cleaning device and the garbage is discharged, which can reduce the operation process of manually disassembling the dust cup and improve the user experience.

[0054] It should be noted that the second dust collecting cavity 210 of the base station 200 can be provided with a dust bag 211, and the dust bag 211 is used to collect the garbage from the first dust collecting cavity 111 for subsequent removal and disposal. The dust bag 211 has a certain air permeability, so that the airflow can pass through the dust bag 211, and the garbage can be left in the dust bag 211. Optionally, the dust bag 211 can be provided with a filter portion for allowing the airflow to pass through and the garbage to be blocked in the dust bag 211. The dust bag 211 can be provided with a secondary filter portion to increase the blocking effect of the garbage. Since the base station 200 has a simpler structure, a larger available space, and a more fixed placement position compared with the cleaning device 100, it is more convenient to recycle the garbage into the base station 200 and then remove and dispose it than to directly remove and dispose the garbage in the cleaning device 100.

[0055] Please refer to Figure 2 The cleaning device 100 includes a shell assembly 110 and a negative pressure generating piece 120. The shell assembly 110 is formed with a first dust collecting cavity 111, a dust suction port 112, an air outlet 113, a pulse port 114, and a dust discharge port 115 which are in communication with the first dust collecting cavity 111.

[0056] In combination with Figure 2 In the dust suction mode, the air outlet 113 is opened and in communication with the negative pressure generating piece 120, and the dust suction port 112 is opened in the dust suction mode. In the dust suction mode, the negative pressure generating piece 120 works to suck the dust and garbage from the dust suction port 112 into the cleaning device 100, and part or all of the garbage entering the cleaning device 100 can fall into the first dust collecting cavity 111.

[0057] In combination with Figure 1 and Figure 3In the dust discharging mode, the negative pressure generating piece 120 is in communication with the second dust collecting cavity 210 of the base station 200, and the pulse port 114 is opened and closed in a pulse form, and the dust discharging port 115 is opened. In the dust discharging mode, the negative pressure generating piece 120 works to bring the garbage in the first dust collecting cavity 111 into the second dust collecting cavity 210 of the base station 200, so as to realize the discharge of the garbage in the cleaning device 100. The dust collecting mode and the dust discharging mode of the embodiment of the application share the same negative pressure generating piece 120, which can reduce the manufacturing cost and the weight of the cleaning system 10, compared with the negative pressure generating piece 120 arranged on the cleaning device 100 and the base station 200 respectively. The negative pressure generating piece 120 can be a fan, which is not limited in the embodiment of the application.

[0058] The pulse port 114 is opened in a pulse form, and a large amount of airflow will enter the first dust collecting cavity 111 at the moment when the pulse port 114 is opened. The large amount of airflow generated at the moment can more easily bring the dust in the first dust collecting cavity 111 into the second dust collecting cavity 210, so as to meet the dust discharging requirement from the first dust collecting cavity 111 to the second dust collecting cavity 210 even if the low-power negative pressure generating piece 120 is used. The low-power negative pressure generating piece 120 has a smaller power consumption, which can reduce the use cost. In addition, the pulse port 114 of the embodiment of the application is different from the dust collecting port 112, the air outlet 113 and the dust discharging port 115, and the opening and closing control is relatively independent, so that the operation is more simple.

[0059] It should be noted that the pulse port 114 is opened and closed in a pulse form, which means that the pulse port 114 is opened for a short duration and then quickly returns to the closed state. Alternatively, the pulse port 114 can be opened and closed in a periodic pulse form, so that the garbage in the first dust collecting cavity 111 can be continuously brought into the second dust collecting cavity 210.

[0060] Alternatively, the dust discharging mode includes a first stage and a second stage. In the first stage, the negative pressure generating piece 120 is in communication with the second dust collecting cavity 210, and the dust discharging port 115 is opened and the pulse port 114 is closed. At this time, the second dust collecting cavity 210 and the first dust collecting cavity 111 are in a negative pressure state by the negative pressure generating piece 120. In the second stage, the negative pressure generating piece 120 is in communication with the second dust collecting cavity 210, and the dust discharging port 115 is opened and the pulse port 114 is opened and closed in a pulse form. At this time, when the pulse port 114 is opened in a pulse form, the first dust collecting cavity 111 in the negative pressure state will cause a large amount of airflow to rush into the first dust collecting cavity 111 at the moment when the pulse port 114 is opened, and the garbage in the first dust collecting cavity 111 is brought into the second dust collecting cavity 210 of the base station 200. The large amount of airflow at the moment more easily brings the garbage in the first dust collecting cavity 111 into the second dust collecting cavity 210.

[0061] Optionally, the air outlet passage of the negative pressure generating piece 120 is separated from the air inlet passage of the pulse port 114. For example, the air outlet of the negative pressure generating piece 120 is in communication with the atmosphere, and the pulse port 114 is in communication with the atmosphere when the pulse port 114 is opened. In this way, in the dust collection mode, the air flow sucked in through the dust collection port 112 can be discharged to the atmosphere through the air outlet 113 and the air outlet of the negative pressure generating piece 120. In the first stage of the dust discharge mode, the air flow in the second dust collection cavity 210 can be discharged to the atmosphere through the air outlet of the negative pressure generating piece 120, so that the second dust collection cavity 210 and the first dust collection cavity 111 are in a negative pressure state; and in the second stage of the dust discharge mode, and when the pulse port 114 is opened, the air flow in the atmosphere can enter the first dust collection cavity 111 through the pulse port 114, thereby bringing the garbage in the first dust collection cavity 111 into the second dust collection cavity 210 through the dust discharge port 115, that is, using the normal temperature air flow in the atmosphere to drive the garbage in the first dust collection cavity 111 to reach the second dust collection cavity 210, and compared with the hot air flow directly entering the second dust collection cavity 210 through the pulse port 114, the dust discharge effect is better.

[0062] Optionally, the cleaning device 100 further comprises a driving piece 130 corresponding to the pulse port 114, for opening and closing the pulse port 114 in the form of pulses in the dust discharge mode. The pulse port 114 is opened and closed in the form of pulses by the driving piece 130, which can be more convenient and intelligent in operation. The driving piece 130 can include a fixed part and a movable part, the fixed part can be connected to the shell assembly 110, etc., and the movable part can move relative to the fixed part to close or open the pulse port 114 during movement. For example, the driving piece 130 can include an electric push rod, an electromagnetic valve, a combination of a motor and an eccentric wheel, etc., which are not limited in the embodiments of the present application.

[0063] Optionally, in combination with Figure 1 , the cleaning device 100 further comprises a switching valve 140 for switching the communication path of the negative pressure generating piece 120 in the dust collection mode and the dust discharge mode. Specifically, the switching valve 140 is formed with a communication passage 1411, in combination with Figure 2 , the communication passage 1411 is in communication with the air outlet 113 and the negative pressure generating piece 120 in the dust collection mode, so that the negative pressure generating piece 120 is in communication with the air outlet 113 of the first dust collection cavity 111 in the dust collection mode. In combination with Figure 1 , the communication passage 1411 is in communication with the second dust collection cavity 210 and the negative pressure generating piece 120 in the dust discharge mode, so that the negative pressure generating piece 120 is in communication with the second dust collection cavity 210 in the dust discharge mode. The switching valve 140 switches the communication mode of the negative pressure generating piece 120, which can simplify the structure of the cleaning device 100 compared with directly switching the design of the negative pressure generating piece 120.

[0064] In an exemplary scheme, the switching valve 140 as a whole can be movably connected with the shell assembly 110 and / or the negative pressure generating member 120. When the switching valve 140 is moved (e.g., rotated, etc.) relative to the shell assembly 110 and / or the negative pressure generating member 120, the switching of the communication mode of the negative pressure generating member 120 is achieved.

[0065] In another exemplary scheme, referring to Figure 4 , the switching valve 140 comprises a valve body 141, a first opening and closing member 142, and a second opening and closing member 143. The valve body 141 is formed with a communication passage 1411, and a first air inlet 1412, a second air inlet 1413, and an air outlet 1414 in communication with the communication passage 1411. The air outlet 1414 is in communication with the negative pressure generating member 120. The first opening and closing member 142 is arranged corresponding to the first air inlet 1412, and the second opening and closing member 143 is arranged corresponding to the second air inlet 1413.

[0066] Please refer to Figure 4 , in the dust suction mode, the first opening and closing member 142 opens the first air inlet 1412 to connect the first air inlet 1412 with the air outlet 113. In the dust suction mode, the second opening and closing member 143 closes the second air inlet 1413 to disconnect the second air inlet 1413 from the second dust collecting chamber 210 / ambient. Please refer to Figure 3 , in the dust discharge mode, the first opening and closing member 142 closes the first air inlet 1412 to disconnect the first air inlet 1412 from the air outlet 113. In the dust discharge mode, the second opening and closing member 143 opens the second air inlet 1413 to connect the second air inlet 1413 with the second dust collecting chamber 210. Since the sizes of the first opening and closing member 142 and the second opening and closing member 143 are relatively small compared with the size of the valve body 141, the first opening and closing member 142 can be designed to open and close the first air inlet 1412, and the second opening and closing member 143 can be designed to open and close the second air inlet 1413. Compared with moving the whole switching valve 140, the volume occupied by the switching valve 140 during the switching process can be reduced, and the miniaturization design of the cleaning device 100 can be achieved.

[0067] Optionally, the opening and closing of the second air inlet 1413 by the second opening and closing member 143 can be independent of the opening and closing of the first air inlet 1412 by the first opening and closing member 142. Alternatively, the opening and closing of the second air inlet 1413 by the second opening and closing member 143 can be associated with the opening and closing of the first air inlet 1412 by the first opening and closing member 142. For example, when the second opening and closing member 143 is switched from closing the second air inlet 1413 to opening the second air inlet 1413, the second opening and closing member 143 pushes the first opening and closing member 142 to move to close the first air inlet 1412. When the second opening and closing member 143 is switched from opening the second air inlet 1413 to closing the second air inlet 1413, the second opening and closing member 143 releases the constraint on the first opening and closing member 142, and the first opening and closing member 142 opens the first air inlet 1412. Linking the opening and closing of the second air inlet 1413 by the second opening and closing member 143 with the opening and closing of the first air inlet 1412 by the first opening and closing member 142 can reduce the operation process when the first opening and closing member 142 opens and closes the first air inlet 1412 and the second opening and closing member 143 opens and closes the second air inlet 1413.

[0068] Optionally, the second opening and closing member 143 comprises a push block 1431 corresponding to the second air inlet 1413 and a first compression spring 1432 connecting the push block 1431 and the valve body 141, for driving the push block 1431 to open or close the second air inlet 1413. For example, when the first compression spring 1432 is in a reset state, the push block 1431 closes the second air inlet 1413. When the push block 1431 opens the second air inlet 1413, the first compression spring 1432 is in a compressed state.

[0069] In an exemplary scheme, the first opening and closing member 142 comprises a blocking block corresponding to the first air inlet 1412 and connected to the push block 1431. When the push block 1431 opens the second air inlet 1413, the blocking block closes the first air inlet 1412. When the push block 1431 closes the second air inlet 1413, the blocking block opens the first air inlet 1412. That is, the opening and closing of the second air inlet 1413 by the push block 1431 and the opening and closing of the first air inlet 1412 by the blocking block are both related to the first compression spring 1432, which can simplify the structural design of the switching valve 140. Optionally, the blocking block and the push block 1431 are in an integrated structure to save the assembly process.

[0070] In another exemplary scheme, in combination with Figure 4The first opening and closing member 142 comprises a first valve plate 1421 and a first torsion spring 1422. The first valve plate 1421 is arranged corresponding to the first air inlet 1412 to open or close the first air inlet 1412. The first torsion spring 1422 is arranged at a side of the first air inlet 1412 close to the second air inlet 1413 and connected with the first valve plate 1421 and the valve body 141. For example, when the first torsion spring 1422 is in a reset state, the first valve plate 1421 opens the first air inlet 1412. When the first valve plate 1421 closes the first air inlet 1412, the first torsion spring 1422 is in a torsion state.

[0071] When the push block 1431 is switched from closing the second air inlet 1413 to opening the second air inlet 1413, the push block 1431 pushes the first valve plate 1421 to close the first air inlet 1412 and makes the first torsion spring 1422 in the torsion state. When the push block 1431 is switched from opening the second air inlet 1413 to closing the second air inlet 1413, the push block 1431 releases the constraint on the first valve plate 1421. The first valve plate 1421 moves to open the first air inlet 1412 under the elastic restoring force of the first torsion spring 1422.

[0072] Optionally, the switching valve 140 further comprises a limiting structure for limiting the movement stroke of the push block 1431. For example, the limiting structure comprises a clamping hook for limiting the position of the push block 1431 closing the second air inlet 1413. The clamping hook is connected with the push block 1431. The valve body 141 is provided with a clamping convex matching with the clamping hook. The first compression spring 1432 is designed to move from the compressed state to the reset state. If the clamping hook is connected with the clamping convex when the first compression spring 1432 moves from the compressed state to the reset state, the push block 1431 closes the second air inlet 1413. For another example, the limiting structure comprises a protrusion for limiting the position of the push block 1431 opening the second air inlet 1413. The push block 1431 is designed to abut against the protrusion to open the second air inlet 1413. The protrusion can be arranged on the valve body 141 or the first valve plate 1421. When the protrusion is arranged on the first valve plate 1421, the protrusion can be arranged at the middle part of the first valve plate 1421. When the push block 1431 abuts against the protrusion, the first valve plate 1421 is also inhibited from rotating to open the first air inlet 1412. Thus, the first valve plate 1421 can more stably close the first air inlet 1412.

[0073] When the push block 1431 is switched from closing the second air inlet 1413 to opening the second air inlet 1413, the elastic force of the first compression spring 1432 needs to be overcome. Therefore, the push block 1431 can be manually pushed or the first top pushing rod 220 (see Figure 1The opening of the push block 1431 can be achieved by means of the first push rod 220, the second push rod, or the electric push rod. When the push block 1431 is switched from opening the second air inlet 1413 to closing the second air inlet 1413, the elastic force of the first compression spring 1432 from the compressed state to the reset state can directly drive the movement of the push block 1431, that is, the manual pushing force, the force of the first push rod 220, or the force of the electric push rod can be directly removed.

[0074] It should be noted that when the first push rod 220 is used, the first push rod 220 can be installed on the cleaning device 100 and correspond to the push block 1431, or can be installed on the base station 200, and the embodiments of the present application do not limit this. When the first push rod 220 is used, when the cleaning device 100 is connected to the base station 200, the first push rod 220 can be adjusted by adjusting the distance between the cleaning device 100 and the base station 200 to apply a force. Alternatively, when the first push rod 220 is installed on the cleaning device 100, the first push rod 220 can protrude outward from the cleaning device 100, so that when the cleaning device 100 is connected to the base station 200, it is easier to apply a force to the first push rod 220. Alternatively, when the first push rod 220 is installed on the base station 200, the first push rod 220 can protrude outward from the base station 200, so that when the cleaning device 100 is connected to the base station 200, it is easier to apply a force to the first push rod 220.

[0075] Alternatively, the cleaning device 100 further comprises a filter 150, which can be arranged in the first dust collecting cavity 111. The filter 150 has opposite first and second surfaces 151 and 152. The dust suction port 112 and the dust discharge port 115 are located on one side of the first surface 151, and the pulse port 114 and the air outlet 113 are located on one side of the second surface 152. In the dust collection mode, the filter 150 can block the garbage entering the first dust collecting cavity 111, so as to prevent the garbage entering the first dust collecting cavity 111 from being further discharged from the air outlet 113 under the action of the negative pressure generating member 120; in the dust collection mode, the airflow flows from the first surface 151 of the filter 150 to the second surface 152. In the dust discharge mode, when the pulse port 114 is opened, a large amount of airflow entering through the pulse port 114 will move from the second surface 152 of the filter 150 to the first surface 151, which has a greater impact on the filter 150, and the impact direction of the airflow on the filter 150 is opposite to that in the dust collection mode. The garbage adhering to the filter 150 in the dust collection mode can be removed, and the garbage falls into the first dust collecting cavity 111 close to the dust discharge port 115, so as to avoid blockage of the filter 150 and facilitate discharge in the dust discharge mode. The embodiments of the present application can self-clean the garbage adhering to the filter 150 in the dust discharge mode, which can save manual labor compared with manual disassembly and cleaning.

[0076] Optionally, the distance between the filter 150 and the pulse port 114 along the direction of the airflow entering the first dust collection cavity 111 through the pulse port 114 is greater than or equal to 2 mm, so that there is sufficient distance between the pulse port 114 and the filter 150 to ensure sufficient air intake. Optionally, the distance between the filter 150 and the pulse port 114 along the direction of the airflow entering the first dust collection cavity 111 through the pulse port 114 can be 2 mm, 3 mm, 5 mm, 7 mm, etc.; preferably, the distance between the filter 150 and the pulse port 114 is 2 mm, so as to enhance the impact of the airflow on the filter 150 when the pulse port 114 is opened in the dust discharge mode, thereby achieving better cleaning effect. Of course, the distance between the filter 150 and the pulse port 114 can also be designed in combination with the actual situation, and the present application does not limit this.

[0077] Optionally, the filter 150 includes a first filter 153 and a second filter 154, the first filter 153 is arranged in the first dust collection cavity 111, the second filter 154 is arranged in the first dust collection cavity 111 and has better filtering performance than the first filter 153, the second filter 154 is arranged close to the pulse port 114 and the air outlet 113 relative to the first filter 153, and the first filter 153 is arranged close to the dust suction port 112 and the dust discharge port 115 relative to the second filter 154. The first filter 153 can be a filter screen or the like, which can achieve preliminary filtration of garbage, and the second filter 154 can be a high-efficiency filter (e.g., HEPA, High Efficiency Particulate Air Filter), which can achieve secondary filtration of garbage and improve the collection effect of the cleaning device 100 on garbage. Optionally, the first filter 153 and the second filter 154 can be arranged in abutment or have a certain gap therebetween.

[0078] Optionally, the side of the second filter 154 away from the first filter 153 can be arranged in abutment with the inner wall of the first dust collection cavity 111 formed by the shell assembly 110. Optionally, the filter 150 can also divide the first dust collection cavity 111 into a first sub-cavity 1111 on the side of the first surface 151 and a second sub-cavity 1112 on the side of the second surface 152, the dust suction port 112 and the dust discharge port 115 are in communication with the first sub-cavity 1111, and the pulse port 114 and the air outlet 113 are in communication with the second sub-cavity 1112, so as to ensure smooth airflow.

[0079] Optionally, please refer to Figure 5 and Figure 6, the cleaning device 100 further comprises a third opening and closing member 161 corresponding to the dust suction port 112, the third opening and closing member 161 opens the dust suction port 112 in the dust collection mode and closes the dust suction port 112 in the dust discharge mode, the third opening and closing member 161 comprises a second valve plate 1611 and a second torsional spring 1612, the second valve plate 1611 is arranged corresponding to the dust suction port 112 to open or close the dust suction port 112, and the second torsional spring 1612 is connected to the second valve plate 1611 and the shell assembly 110. For example, when the second torsional spring 1612 is in the reset state, the second valve plate 1611 closes the dust suction port 112, and when the second valve plate 1611 opens the dust suction port 112, the second torsional spring 1612 is in the torsion state.

[0080] In the dust collection mode, when the negative pressure generating member 120 communicates with the air outlet 113 to generate negative pressure in the first dust collecting cavity 111, the elastic force of the second torsional spring 1612 can be overcome to open the dust suction port 112 by the second valve plate 1611, at this time, the second torsional spring 1612 is in the torsion state. In the dust discharge mode, the second valve plate 1611 can be closed under the action of the restoring force of the second torsional spring 1612, at this time, the second valve plate 1611 can be closed by the first locking member 1621 and the like. For example, the first locking hole 116 can be arranged on the shell assembly 110, the second locking hole 1613 can be arranged on the second valve plate 1611, and when the second valve plate 1611 closes the dust suction port 112 in the dust discharge mode, the first locking member 1621 can be inserted into the first locking hole 116 and the second locking hole 1613 to maintain the second valve plate 1611 closing the dust suction port 112; in the dust collection mode, the first locking member 1621 can not be inserted into the first locking hole 116 and the second locking hole 1613 at the same time, so that it is only inserted into the first locking hole 116, only inserted into the second locking hole 1613, or neither inserted into the first locking hole 116 nor inserted into the second locking hole 1613, so that when the first dust collecting cavity 111 forms negative pressure, the elastic force of the second torsional spring 1612 can be overcome to open the dust suction port 112 by the second valve plate 1611.

[0081] Optionally, the cleaning device 100 further comprises a fourth opening and closing member 163 corresponding to the dust discharge port 115, the fourth opening and closing member 163 closes the dust discharge port 115 in the dust collection mode and opens the dust discharge port 115 in the dust discharge mode, the fourth opening and closing member 163 comprises a third valve plate 1631 and a third torsional spring 1632, the third valve plate 1631 is arranged corresponding to the dust discharge port 115 to open or close the dust discharge port 115, and the third torsional spring 1632 is connected to the third valve plate 1631 and the shell assembly 110. Among them, when the third torsional spring 1632 is in the reset state, the third valve plate 1631 opens the dust discharge port 115, and when the third valve plate 1631 closes the dust discharge port 115, the third torsional spring 1632 is in the compression state.

[0082] In the dust collection mode, the third valve plate 1631 can be maintained to close the dust outlet 115 by the second locking member 1622 and the like. For example, the third valve plate 1631 can be provided with a third locking hole 1633, and when the third valve plate 1631 closes the dust outlet 115 in the dust collection mode, the second locking member 1622 can be inserted into the third locking hole 1633 and connected with the third locking hole 1633 in interference, so as to maintain the third valve plate 1631 to close the dust outlet 115; and in the dust discharge mode, the second locking member 1622 can not be inserted into the third locking hole 1633, so that the third valve plate 1631 is opened under the elastic restoring force of the third torsional spring 1632. It should be noted that the fourth opening and closing member 163 can include the third valve plate 1631 and a driving part connected with the third valve plate 1631, in addition to the third valve plate 1631 and the third torsional spring 1632, so that the driving part drives the third valve plate 1631 to move to close the dust outlet 115 in the dust collection mode, and drives the third valve plate 1631 to move to open the dust outlet 115 in the dust discharge mode. Hereinafter, the fourth opening and closing member 163 will be described in detail by taking the example that the fourth opening and closing member 163 includes the third valve plate 1631 and the third torsional spring 1632.

[0083] The first locking member 1621 and the second locking member 1622 can be independent of each other, or can be connected with each other to form the locking member 162 together. When the first locking member 1621 and the second locking member 1622 are connected with each other, the assembly process can be simplified.

[0084] Optionally, in the dust collection mode, the locking member 162 is inserted into the first locking hole 116 and the third locking hole 1633, so as to maintain the third valve plate 1631 to close the dust outlet 115; and in the dust discharge mode, the locking member 162 is inserted into the first locking hole 116 and the second locking hole 1613, so as to maintain the second valve plate 1611 to close the dust inlet 112.

[0085] Optionally, the connection of the locking member 162 to the second valve plate 1611 and the connection of the locking member 162 to the third valve plate 1631 can be linked. For example, in the dust collection mode, when the locking member 162 is connected to the third valve plate 1631 (e.g., the locking member 162 is inserted into the third locking hole 1633), the locking member 162 is disconnected from the second valve plate 1611 (e.g., the locking member 162 is not inserted into the first locking hole 116 and the second locking hole 1613), so that when the first dust collection chamber 111 forms a negative pressure in the dust collection mode, the elastic force of the second torsional spring 1612 can be overcome to open the dust suction port 112 by the second valve plate 1611, and the third valve plate 1631 will remain closed to the dust discharge port 115 under the action of the locking member 162. In the dust discharge mode, when the locking member 162 is connected to the second valve plate 1611 (e.g., the locking member 162 is inserted into the first locking hole 116 and the second locking hole 1613), the locking member 162 is disconnected from the third valve plate 1631 (e.g., the locking member 162 is not inserted into the third locking hole 1633), so that the third valve plate 1631 can be opened to the dust discharge port 115 under the elastic restoring force of the third torsional spring 1632 in the dust discharge mode, and the second valve plate 1611 will remain closed to the dust suction port 112 under the action of the locking member 162.

[0086] Optionally, a second compression spring 164 can be connected between the shell assembly 110 and the locking member 162. When the locking member 162 is connected to the third valve plate 1631 and disconnected from the second valve plate 1611, the second compression spring 164 can be in a reset state; when the locking member 162 is connected to the second valve plate 1611 and disconnected from the third valve plate 1631, the second compression spring 164 can be in a compressed state. At this time, under normal circumstances, the locking member 162 is disconnected from the second valve plate 1611, which facilitates the opening of the second valve plate 1611 to the dust suction port 112 in the dust collection mode.

[0087] When the locking member 162 is switched from being connected to the third valve plate 1631 and disconnected from the second valve plate 1611 to being connected to the second valve plate 1611 and disconnected from the third valve plate 1631, the elastic force of the second compression spring 164 needs to be overcome, so in this process, the locking member 162 can be moved and the second compression spring 164 can be in a compressed state by means of manual pushing, the second top pushing rod 230 (see Figure 1 ), an electric push rod, etc. When the locking member 162 is switched from being connected to the second valve plate 1611 and disconnected from the third valve plate 1631 to being connected to the third valve plate 1631 and disconnected from the second valve plate 1611, the elastic force of the second compression spring 164 can be directly used to drive the locking member 162 to move from the compressed state to the reset state, i.e., the manual pushing force, the second top pushing rod 230 force or the electric push rod force can be directly removed.

[0088] It should be noted that, in the mode of using the second pushing rod 230, the second pushing rod 230 can be installed on the cleaning device 100 and correspond to the locking piece 162, or can be installed on the base station 200, and the embodiments of the present application do not limit this. In the mode of using the second pushing rod 230, when the cleaning device 100 is connected with the base station 200, the second pushing rod 230 can be applied with a force by adjusting the distance between the cleaning device 100 and the base station 200. Alternatively, when the second pushing rod 230 is installed on the cleaning device 100, the second pushing rod 230 can protrude outward from the cleaning device 100, so that when the cleaning device 100 is connected with the base station 200, it is easier to apply a force to the second pushing rod 230. Alternatively, when the second pushing rod 230 is installed on the base station 200, the second pushing rod 230 can protrude outward from the base station 200, so that when the cleaning device 100 is connected with the base station 200, it is easier to apply a force to the second pushing rod 230.

[0089] Alternatively, in combination with Figures 1 to 3 The cleaning device 100 of the embodiments of the present application can be a handheld vacuum cleaner, in combination with Figure 7 The cleaning device 100 of the embodiments of the present application can also be a stick vacuum cleaner, and the embodiments of the present application do not limit this. Alternatively, part of the stick vacuum cleaner can be formed into a handheld vacuum cleaner, so as to be able to be flexibly changed according to user needs. For example, when cleaning a dust accumulation area such as a floor, a stick vacuum cleaner can be used; and when cleaning a dust accumulation area such as a sofa surface or a seat surface, the handheld vacuum cleaner on the stick vacuum cleaner can be removed for use. This scheme has been disclosed in related technologies, and the embodiments of the present application will not be described again.

[0090] For the case that part of the stick vacuum cleaner can be formed into a handheld vacuum cleaner, please refer to Figure 8 Preferably, the second pushing rod 230 for pushing the locking piece 162 and the first pushing rod 220 for pushing the pushing block 1431 can both be installed on the base station 200, so that when the stick vacuum cleaner is used in cooperation with the base station 200 for dust removal, and when the handheld vacuum cleaner is used in cooperation with the base station 200 for dust removal, the first pushing rod 220 and the second pushing rod 230 on the base station 200 can respectively apply a pushing force to the pushing block 1431 and the locking piece 162.
