Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., as in "sidewall"), etc., to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

At this time, when the number of the first type interfaces 221 is one, 3 air channel ports (i.e., including one first type interface 221 and two second type interfaces 222) are uniformly distributed along the circumferential direction of the air channel switching part 220, in other words, the centers of the three air channel ports, i.e., the first type interfaces 221 and the second type interfaces 222, are located on a circle centered on the rotation axis of the air channel switching part 220 and are uniformly distributed along the circumferential direction of the circle, whereby the air channel switching part 220 can be more conveniently controlled.

Of course, the first type interface 221 and the second type interface 222 may be unevenly distributed, as long as the distance between the first type interface 221 and one of the second type interfaces 222 is the same as the distance between the first type interface 221 and the other of the second type interfaces 222.

The air duct switching part 220 is driven to be able to be located at a first position and a second position, when the air duct switching part 220 is located at the first position, the air inlet of the suction device 210 is communicated with at least one of the second type interfaces 222, the other of the second type interfaces 222 is communicated with the air duct 270, the air outlet of the air duct switching part 220 is communicated with the first type interface 221, when the air duct switching part 220 is located at the second position, the air inlet of the suction device 210 is communicated with the first type interface 221 of the air duct switching part 220, the air outlet of the suction device 210 is communicated with at least one of the second type interfaces 222 of the air duct switching part 220, and the other of the second type interfaces 222 is communicated with the air duct 270, thereby enabling both air inlet and air outlet switching through one suction device 210, and further enabling negative pressure and positive pressure to be provided to the recovery storage part when the device for automatically switching the air duct is connected to the recovery storage part. The recovery storage section is enabled to suck the sewage of the surface cleaning apparatus when the negative pressure is supplied to the recovery storage section, and the sewage stored in the recovery storage section is enabled to be discharged to the outside of the recovery storage section when the positive pressure is supplied to the recovery storage section.

In the present disclosure, the rotation axis of the air channel switching unit 220 is the same as the rotation axis of the driving shaft of the first driving device 240, that is, when the first driving device 240 drives the air channel switching unit 220 to rotate, the air channel switching unit 220 does not generate eccentric motion.

The first driving device 240 may be disposed in the housing part 250, and at this time, the housing part 250 is formed with an accommodating space accommodating the first driving device 240, the first driving device 240 is disposed in the accommodating space of the housing part 250, and at least part of the first driving device 240 is located outside the housing part 250, for example, an upper end of a driving shaft of the first driving device 240 is located outside the housing part 250, so that the first driving device 240 is connected with the duct switching part 220.

The bracket part 230 serves to provide a guide to the movement of the housing part 250, for example, the inside of the bracket part 230 is formed with two relatively parallel planes, and the housing part 250 is disposed between the two relatively parallel planes, guided by the planes when the housing part 250 moves.

In the present disclosure, the housing portion 250 can move in a vertical direction, that is, the linear driving structure 260 can drive the housing portion 250 to move up and down.

Fig. 6 is a schematic structural diagram of a base station according to one embodiment of the present disclosure. Fig. 7 is a partial schematic structure of a base station according to one embodiment of the present disclosure. Fig. 8 is a cross-sectional view of fig. 7. Fig. 9 is another angular schematic view of fig. 7.

According to another aspect of the present disclosure, as shown in fig. 6 to 9, the present disclosure provides a base station 10 including the above-described apparatus 200 for automatically switching air ducts.

The recovery storage unit of the present disclosure connects the gas pipe 270 of the device 200 for automatically switching the air duct to the air port of the recovery storage unit (i.e., to the lower end of the gas channel 780 of the recovery storage unit 700) when sucking the sewage of the surface cleaning apparatus, and controls the air duct switching unit 220 to be located at the first position, and the suction device 210 can suck the gas from the recovery storage unit at this time, thereby realizing the suction of the sewage of the surface cleaning apparatus.

On the other hand, when the sewage in the recovery storage portion is discharged, the air duct switching portion 220 is controlled to be located at the second position, and at this time, the suction device 210 can suck the air from the outside and apply the air to the recovery storage portion after pressurizing, thereby pushing out the sewage from the recovery storage portion by the high pressure of the air in the recovery storage portion.

In the present disclosure, when the air duct switching part 220 moves between the first position and the second position, the air duct switching part 220 may be first lowered by a certain distance, then the air duct switching part 220 is driven to rotate, and then the air duct switching part 220 is controlled to rise by a certain distance, so that the air duct switching part 220 can be conveniently controlled.

Therefore, the device 200 for automatically converting the air duct can generate positive pressure and negative pressure, sucking sewage of the surface cleaning equipment and discharging sewage in the recovery storage part, so that the structure of the base station 10 is simplified, the volume of the base station 10 is reduced, and the cost of the base station 10 is reduced.

Fig. 10 is a partial structural schematic diagram of a case portion according to one embodiment of the present disclosure. Fig. 11 is another angular schematic view of fig. 10. Fig. 12 is a partially schematic cross-sectional view of a tank portion according to one embodiment of the present disclosure.

As one preferable example, as shown in fig. 10 to 12, the recovery storage section 700 includes: a tank part 710, a storage space containing liquid is formed inside the tank part 710, so that when the recovery storage part 700 is installed at a base station, a solid-liquid mixture in a sewage tank of the surface cleaning apparatus can be sucked into the recovery storage part 700 of the base station, and the recovery storage part 700 can be connected to a sewer, thereby discharging the solid-liquid mixture to the sewer.

The tank portion 710 is formed with a liquid inlet and a liquid outlet so that a solid-liquid mixture can enter the tank portion 710 through the liquid inlet and be discharged from the tank portion 710 through the liquid outlet. That is, when the base station is in different operation states, the tank 710 is also in different states, for example, when the base station sucks the solid-liquid mixture in the surface cleaning apparatus, negative pressure may be applied to the tank 710 by the device 200 for automatically switching the air duct, so that the solid-liquid mixture is sucked and stored in the storage space of the tank 710; when the base station discharges the solid-liquid mixture, positive pressure may be applied to the tank part 710 by the device 200 for automatically switching an air duct, that is, gas is continuously supplied to the tank part 710, so that the solid-liquid mixture in the tank part 710 is discharged to the outside of the tank part 710 through the liquid discharge port.

On the other hand, the tank portion 710 has an open top to apply negative or positive pressure to the tank portion 710 through the open top.

As a preferred implementation form, the liquid inlet and the liquid outlet of the tank 710 are located on the side wall of the tank 710, and the liquid inlet and the liquid outlet may be located on the middle upper portion of the side wall of the tank 710, so as to prevent sewage from leaking through the liquid inlet and the liquid outlet.

Of course, the drain port may be located at the bottom of the tank 710, and the second valve 730 may be an on-off valve such as a solenoid valve. The liquid inlet may be located at the bottom of the tank 710, and the first valve 720 may be a switch valve such as a solenoid valve. Of course, in the present disclosure, it is a preferred embodiment of the present disclosure that the liquid inlet and the liquid outlet are located at the middle upper portion of the side wall of the tank 710.

The recovery storage section 700 may include a first valve 720, and the first valve 720 is used to selectively open or close the liquid inlet of the tank 710. Specifically, the first valve 720 includes: and the cover plate part is used for closing the liquid inlet when being positioned at a first position and opening the liquid inlet when being positioned at a second position.

As one implementation, the cover plate part is moved from a first position to a second position or from the second position to the first position by rotation of the cover plate part; as another implementation form, the cover plate part is moved from the first position to the second position or from the second position to the first position by the movement of the cover plate part, and at this time, the cover plate part can be driven to move by a linear driving structure.

When the cover plate portion is rotatable, the cover plate portion is driven to move from a first position to a second position when negative pressure is applied to the case portion 710; the cover portion moves from the second position to the first position when the application of negative pressure to the tank portion 710 is stopped or when positive pressure is applied to the tank portion 710.

Specifically, when negative pressure is applied to the case portion 710, the cover plate portion is driven to move from the first position to the second position; the cover portion moves from the second position to the first position when the application of negative pressure to the tank portion 710 is stopped or when positive pressure is applied to the tank portion 710.

In the present disclosure, the cover plate portion may be moved from the second position to the first position by the gravity of the cover plate portion, and at this time, the first valve 720 may be in a normally closed state, that is, when the base station is not in a working state, the first valve 720 may close the liquid inlet.

Structurally, the cover plate part is located inside the case part 710, and an upper end of the cover plate part is hinged to the case part 710 so that the cover plate part can swing. Still further, the cover plate portion is located in a horizontal plane with respect to the hinge shaft of the case portion 710.

Of course, the upper end of the cover part may be hinged to the cover 760, for example, to the shielding part 761 of the cover 760, and the cover part may be swingable.

In the present disclosure, the tank 710 includes an inclined wall portion inclined toward the inside of the tank 710 in a top-to-bottom direction, wherein the liquid inlet is formed on the inclined wall portion; correspondingly, the tank body 710 is further connected with a liquid inlet pipe, the liquid inlet pipe is located outside the tank body 710, and the connection part of the liquid inlet pipe and the liquid inlet is also arranged obliquely, so that the recovery storage part can be conveniently installed on the base station; in this disclosure, the tank 710 and the inlet pipe bracket may be provided with a sealing device, which will not be described in detail herein.

In the present disclosure, when the cover plate part is located at the first position, the cover plate part is attached to the inner surface of the inclined wall part; so that the cover plate part is in sealing contact with the box body part 710 and can seal the liquid inlet; accordingly, when the cover plate part is located at the second position, the cover plate part maintains a preset interval with the inner surface of the inclined wall part, and a gap exists between the cover plate part and the inclined wall part, so that the solid-liquid mixture entering through the liquid inlet can pass through the gap between the cover plate part and the inclined wall part and enter the storage space of the tank 710.

The recovery storage section 700 may include a second valve 730, the second valve 730 for selectively opening or closing the drain port of the tank section 710; specifically, the second valve 730 includes a shutter portion that is caused to close the liquid discharge port when the shutter portion is in the first position, and is caused to open the liquid discharge port when the shutter portion is in the second position.

In this disclosure, the recovery storage part 700 may further include a drain channel 740, one end of the drain channel 740 is formed as a drain port, and the other end of the drain channel 740 is in communication with the storage space of the tank 710, wherein a communication position between the drain channel 740 and the tank 710 is located at the bottom of the tank 710 or at the lower half of the sidewall of the tank 710.

In the present disclosure, in order to allow all or most of the liquid in the tank 710 to be discharged to the outside of the tank 710, the lowest position of the communication between the drain channel 740 and the tank 710 is not higher than the inner surface of the bottom wall of the tank 710; specifically, the connection between the drain channel 740 and the tank 710 may be located at the bottom wall of the tank 710, and at this time, the bottom wall may be horizontal or the bottom wall may be inclined, and the connection is at the lowest point of the inclined bottom wall.

As another implementation form, the connection between the drain channel 740 and the tank 710 is located at the side wall of the tank 710, so that the bottom wall may be horizontal at this time, but the bottom wall of the tank 710 may be inclined, considering that the liquid in the tank 710 is more easily drained, and the connection is located near the lowest point of the inclined bottom wall.

In the present disclosure, the shutter portion is moved from the first position to the second position or from the second position to the first position by rotation of the shutter portion.

Specifically, the shutter portion can be opened or closed based on the application of negative or positive pressure to the case portion 710, for example, when negative pressure is applied to the case portion 710, the shutter portion is driven to move from the second position to the first position; when positive pressure is applied to the tank portion 710, the flapper portion moves from a first position to a second position.

In the present disclosure, when the application of negative pressure to the tank portion 710 is stopped, the barrier portion can be maintained at the first position, that is, the liquid discharge port is closed, that is, the barrier portion can be moved from the second position to the first position by the gravity of the barrier portion.

Structurally, the baffle portion is located outside the housing portion 710, but the baffle portion may be located inside the housing portion 710. The following description will be made only with the baffle portion located outside the case portion 710, and those skilled in the art will understand that the structure of the baffle portion when it is located inside the case portion 710 is similar to that shown in the drawings, and will not be described in detail.

When the baffle portion is located outside the case portion 710, the recovery storage portion 700 may further include a drain pipe 750, the drain pipe 750 being connected to the drain port, wherein the baffle portion is hinged to an inner wall of the drain pipe 750.

Preferably, the hinge axis of the baffle portion and the inner wall of the drain pipe 750 is located in a certain horizontal plane.

More specifically, the drain pipe 750 has a stepped portion formed inside thereof, and when the baffle portion is located at the second position, the baffle portion is spaced apart from the stepped portion by a predetermined distance, and a gap is formed between the baffle portion and the stepped portion, so that the liquid discharged through the liquid discharge port is discharged to the outside of the base station through the gap between the baffle portion and the stepped portion.

On the other hand, when the barrier portion is located at the first position, the barrier portion is attached to the step portion, and at this time, the barrier portion may be brought into sealing contact with the step portion, so that when negative pressure is applied to the tank portion 710, gas is prevented from entering from the liquid discharge passage, and the effect of sucking the solid-liquid mixture is reduced.

In the present disclosure, when the baffle portion is located at the first position, the baffle portion is disposed vertically, and of course, the baffle portion may be disposed obliquely, for example, an oblique direction of the baffle portion is the same as an oblique direction of the oblique wall portion.

As another implementation, the shutter portion may be moved from the first position to the second position or from the second position to the first position by movement of the shutter portion, for example, the shutter portion may be driven to move by a linear driving structure.

Thus, when negative pressure is applied to the tank 710, the first valve 720 opens the liquid inlet of the tank 710, and the second valve 730 closes the liquid outlet of the tank 710, so that the solid-liquid mixture enters the tank 710 through the liquid inlet; when positive pressure is applied to the tank 710, the first valve 720 closes the liquid inlet of the tank 710, and the second valve 730 opens the liquid outlet of the tank 710 so that the solid-liquid mixture is discharged from the tank 710 through the liquid outlet.

Fig. 13 is a schematic perspective view of a case according to an embodiment of the present disclosure. Fig. 14 is a schematic top view of a case portion according to one embodiment of the present disclosure.

As shown in fig. 13 and 14, the tank portion 710 of the present disclosure may further include a gas passage 780 for providing a high-pressure gas to the tank portion 710 or providing a negative pressure to enable the tank portion 710 to discharge a solid-liquid mixture therein or suck the solid-liquid mixture. In the present disclosure, one end of the gas passage 780 may communicate with the gas flow passage, and the filter assembly 770 may be located at an upstream side of the gas passage 780 in a gas flow direction when negative pressure is provided to the tank 710.

On the other hand, the gas channel 780 is disposed in a vertical direction or a substantially vertical direction, so that one port of the gas channel 780 (i.e., the other end of the gas channel) is located at the bottom of the case 710, and at this time, the gas channel 780 may be disposed at one side of the case 710 side by side with the drain channel, so as to save the arrangement space of the case 710.

According to one embodiment of the present disclosure, as shown in fig. 15, the recovery storage section 700 may further include a cover 760, and the cover 760 may be formed with a gas circulation passage to apply negative or positive pressure to the tank 710 through the gas circulation passage.

More preferably, a filter member 770 is provided in the gas flow path so that the gas drawn out of the tank 710 and the gas supplied to the tank 710 pass through the filter member 770. In an alternative embodiment, the filter assembly 770 may be a HEPA assembly.

The cover 760 is provided to the case 710, and at least a portion of the cover 760 is positioned within the case 710, wherein an outer circumferential surface of the cover 760 is in sealing contact with an inner surface of an open top of the case 710.

In the present disclosure, the cover 760 includes a shielding portion 761, and one end of the shielding portion 761 extends to the inclined wall portion and is located above the liquid inlet, so as to prevent the liquid entering through the liquid inlet from directly entering the gas circulation channel.

The recycling storage part 700 of the present disclosure thus has an automatic sewage discharge function, and can automatically discharge a solid-liquid mixture, improving user experience.
