[0035] In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the present disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0036] The terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The singular forms of "a", "the", and "said" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. "Plural" generally includes at least two, and other quantifiers are similar.

[0037] In the description of the present disclosure, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0038] It should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a commodity or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such commodity or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or device including the said element.

[0039] In the related art, the mainstream solution for emptying the sewage bucket or dust collection box of cleaning equipment on the market currently is manual emptying, but this solution has a poor user experience. The existing automatic sewage discharge solutions currently require the main body of the cleaning equipment to be placed in the base station and can only achieve sewage discharge through the cooperation of the automatic sewage discharge system of the base station, which has certain restrictions on user use. At the same time, after discharging the dirt and dust of the cleaning equipment to the base station, it is still necessary to discharge the dirt and dust in the base station, increasing the secondary emptying operation and affecting the user experience.

[0040] Therefore, the present disclosure provides a door opening and closing structure, including: a first fixing frame; a valve assembly, the valve assembly is rotatably connected to the first fixing frame, and the valve assembly has an open position and a closed position; a driving assembly, configured to provide a driving force to switch the valve assembly between the open position and the closed position.

[0041] The door opening and closing structure provided by the present disclosure can be arranged on the cleaning equipment. Through the cooperation of the driving assembly and the valve assembly, the valve assembly is automatically switched between the open position and the closed position corresponding to the open mouth of the container to achieve the automatic sewage discharge function. The cleaning equipment can automatically open the door opening and closing structure to achieve automatic sewage discharge when connected to the base station, and can also achieve automatic sewage discharge when separated from the base station. Thus, the user can also independently choose to actively control the valve assembly of the automatic door opening and closing structure to open for sewage discharge in a suitable scenario, effectively increasing the user's usage scenarios and improving the user experience.

[0042] In view of this, the optional embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] In some embodiments, as Figure 1 shown, the door opening and closing structure includes: a container 100, a valve assembly 300, and a driving assembly 400. The driving assembly 400 is configured to provide a driving force to switch the valve assembly 300 between the open position and the closed position to achieve automatic door opening and closing.

[0044] In the cleaning equipment 700 applied with the door opening and closing structure, a container 100 is provided for accommodating dust or sewage. The container 100 has an open mouth 101, which can communicate the internal space of the container 100 with the external environment.

[0045] A first fixing frame 200 is arranged outside the container 100 for fixing the container 100. In the length direction of the container 100, the length of the first fixing frame 200 is greater than the length of the container 100. A connection hole 201 is arranged at the end of the first fixing frame 200, and the connection hole 201 is used to rotatably connect the valve assembly 300 to the first fixing frame 200.

[0046] In some embodiments, the valve assembly 300 is rotatably connected to the first fixing frame 200, and the valve assembly 300 has an open position for communicating the internal space of the container 100 with the external environment, and a closed position for blocking the opening 101 to enclose the internal space of the container 100 relative to the external environment. During the rotation of the valve assembly 300, the valve assembly 300 can be switched between the open position and the closed position.

[0047] Specifically, the valve assembly 300 includes a valve 310 and a first elastic member 320.

[0048] The valve 310 is rotatably connected to the first fixing frame 200 and is used to block the opening 101 to separate the internal space of the container 100 from the external environment. The valve 310 is arranged in a plate-like structure, and a connecting shaft is provided at one end connected to the first fixing frame 200. The connecting shaft is movably connected to the connecting hole 201 so that the valve 310 can rotate relative to the first fixing frame 200.

[0049] The first elastic member 320 is arranged between the valve 310 and the first fixing frame 200. Specifically, the first elastic member 320 is sleeved outside the connecting shaft, and usually makes the valve 310 tend to be away from the opening 101, so as to drive the valve 310 to switch from the closed position to the open position when there is no external force.

[0050] In some embodiments, the switch door structure further includes a driving assembly 400, and the driving assembly 400 is configured to provide a driving force to switch the valve assembly 300 between the open position and the closed position.

[0051] Specifically, the driving assembly 400 includes a driving motor 410 and a rotating rod 420. The driving motor 410 is arranged outside the container 100 and is used to drive the rotating rod 420 to rotate. The rotating rod 420 can be arranged on the outer wall of the driving motor 410 and rotate under the action of the driving motor 410 to push against the valve 310 to switch the valve 310 from the open position to the closed position; or push against the transmission frame 610 to switch the valve 310 from the closed position to the open position.

[0052] In some embodiments, the rotating rod 420 at least includes a first pushing rod 421, and a first pushing portion 423 is provided at one end of the first pushing rod 421 away from the driving motor 410 for pushing the valve 310 to rotate the valve 310 relative to the first fixing frame 200.

[0053] Further, when the valve 310 is in the open state, the drive motor 410 can drive the first push rod 421 to rotate, so that the first pushing portion 423 contacts the valve 310. Under the action of the drive motor 410, the valve 310 can be switched from the open position to the closed position under the action of the first pushing portion 423.

[0054] When the valve 310 is in the closed position, the drive motor 410 can drive the first push rod 421 to rotate, so that the first pushing portion 423 moves away from the valve 310. When there is no external force pressing the valve 310, the first elastic member 320 can drive the valve 310 to switch from the closed position to the open position.

[0055] In some embodiments, the door opening and closing structure further includes a clamping assembly 500. As Figure 1 , Figure 2 shown, the clamping assembly 500 is disposed on a side of the container 100 away from the first fixing bracket 200 for clamping with the valve assembly 300, so that the valve assembly 300 is clamped to the open mouth 101.

[0056] Specifically, the clamping assembly 500 includes: a second fixing bracket 510 and a clamping member 520.

[0057] As Figure 2 shown, the second fixing bracket 510 is disposed on a side of the container 100 away from the first fixing bracket 200. A clamping member 520 is disposed on a side of the inner surface of the second fixing bracket 510 facing the container 100. The free end of the clamping member 520 extends in the direction of the open mouth 101, and the free end of the clamping member 520 is used for clamping with the valve 310 beyond the plane where the valve 310 is located when the valve 310 is in the closed position.

[0058] Further, the free end of the clamping member 520 extends in the direction of the first elastic member 320. A clamping portion 521 is disposed at the free end of the clamping member 520. A side of the clamping portion 521 away from the open mouth 101 is configured as an inclined surface structure, and a side of the clamping portion 521 facing the open mouth 101 is configured as a plane for clamping with the valve 310, so that the valve 310 is stably in the closed position.

[0059] In some embodiments, a clamping groove 311 is disposed at the free end of the side of the valve 310 away from the open mouth 101. The clamping groove 311 is configured as a groove suitable for clamping with the clamping portion 521 for clamping with the clamping portion 521, so that the valve 310 is stably in the closed position.

[0060] Specifically, asFigure 3 As shown, when the valve 310 is in the open state, the drive motor 410 can drive the first pushing rod 421 to rotate, so that the first pushing portion 423 is adapted to push the valve 310 to make the valve 310 abut against the inclined surface of the engaging portion 521. Further, under the action of the drive motor 410, the free end of the valve 310 can be pushed against the engaging portion 521 along the inclined surface structure, so that the engaging portion 521 moves in a direction away from the valve 310. The free end of the valve 310 is adapted to move along the edge of the engaging portion 521 toward the closed position. When the valve 310 moves to the closed position, the engaging portion 521 is engaged with the engaging groove 311. At this time, the valve 310 is in the closed position, as Figure 4 shown.

[0061] In some embodiments, as Figure 4 、 Figure 5 shown, on one side of the inner wall of the second fixing bracket 510 opposite to the transmission frame 610 of the engaging member 520, a limiting portion 530 is provided. There is a gap between the limiting portion 530 and the engaging member 520. The gap can enable the engaging member 520 and the transmission frame 610 to move in the same direction, so that the engaging portion 521 is engaged with or disengaged from the engaging groove 311. The limiting portion 530 is used to limit the engaging member 520, which can effectively prevent the engaging member 520 from breaking due to excessive bending.

[0062] Specifically, the limiting portion 530 includes a third elastic member 531. When the engaging member 520 is pushed by the first end 611 of the transmission frame 610 to bend away from the container 100 to the edge of the safe bending angle, the side of the engaging member 520 away from the container 100 will abut against the third elastic member 531. Under the abutment of the third elastic member 531, the engaging member 520 cannot continue to move or bend toward the side away from the container 100, avoiding breakage of the engaging member 520 due to excessive bending.

[0063] Further, since the third elastic member 531 has a certain elastic force, after the transmission frame 610 cancels the thrust on the engaging member 520, the third elastic member 531 can be used to assist the engaging member 520 to reset.

[0064] In some embodiments, a gasket 312 is provided on the side of the valve 310 facing the open mouth 101. The gasket 312 can be used to seal the open mouth 101.

[0065] In some embodiments, the door opening and closing structure further includes a transmission assembly 600, as Figure 2 、 Figure 4 、 Figure 5As shown, the transmission assembly 600 is disposed between the drive assembly 400 and the latching assembly 500, and is configured to push against the latching assembly 500 under the action of the drive assembly 400, so that the latching member 520 moves away from the container 100. When the valve 310 is in the closed position, the drive assembly 400 can drive the transmission assembly 600 to release the valve assembly 300 by the latching assembly 500.

[0066] Specifically, the transmission assembly 600 includes a transmission frame 610. The transmission frame 610 is located between the first fixing frame 200 and the second fixing frame 510, and is sleeved outside the container 100 and can move horizontally relative to the container 100. The transmission frame 610 has a first end 611 away from the drive assembly 400 and a second end 612 adjacent to the drive assembly 400.

[0067] Specifically, when the valve 310 is in the closed position, if the transmission frame 610 is moved from the second end 612 towards the first end 611, the first end 611 will push against the latching member 520 to disengage the latching portion 521 from the latching groove 311. Further, under the action of the first elastic member 320, the valve 310 is switched from the closed position to the open position.

[0068] In some embodiments, the transmission assembly 600 further includes a second elastic member 620. The second elastic member 620 is disposed between the second end 612 and the container 100. One end of the second elastic member 620 abuts against the second end 612, so that the second end 612 has a tendency to move away from the container 100.

[0069] Specifically, when the valve 310 is switched from the closed position to the open position, due to the arrangement of the second elastic member 620, the second end 612 has a tendency to move away from the container 100. Therefore, after the latching portion 521 is disengaged from the latching groove 311, the transmission assembly 600 will move and reset towards the direction where the second end 612 is located under the action of the second elastic member 620. Further, the third elastic member 531 assists the latching member 520 to reset.

[0070] In some embodiments, the rotating rod 420 may include a first pushing rod 421 and a second pushing rod 422, as Figure 1 、 Figure 4 shown. A first pushing portion 423 is provided at the end of the first pushing rod 421 for contacting and pushing against the valve 310 to switch the valve 310 from the open position to the closed position.

[0071] The end of the second pushing rod 422 is provided with a second pushing portion 424, and the second pushing portion 424 is used to push the second end 612 of the transmission frame 610. Wherein, in response to the second pushing portion 424 pushing the second end 612 of the transmission frame 610, the first end 611 of the transmission frame 610 pushes against the clamping assembly 500, so that the clamping assembly 500 moves away from the open port 101, and the valve 310 is switched from the closed position to the open position.

[0072] In some embodiments, the first pushing rod 421 and the second pushing rod 422 rotate synchronously.

[0073] When the valve 310 needs to be switched from the open position to the closed position, a closing signal is transmitted to the driving motor 410, so that the driving motor 410 drives the rotating rod 420 to rotate. When the first pushing rod 421 rotates towards the valve 310, the second pushing rod 422 moves away from the transmission frame 610.

[0074] When the first pushing portion 423 pushes the valve 310 to abut against the inclined surface on the side of the clamping portion 521 away from the open port 101, in response to the driving motor 410 driving the first pushing portion 423 to move towards the closed position, the free end of the valve 310 is adapted to move along the inclined surface of the clamping portion 521 towards the closed position. Under the pressure of the valve 310, the clamping portion 521 moves away from the valve 310. When the valve 310 moves to the closed position, the clamping portion 521 is clamped with the clamping groove 311. At this time, the valve 310 completes the switching from the open position to the closed position, and the valve 310 is normally in the closed position without external force pushing.

[0075] When the valve 310 needs to be switched from the closed position to the open position, an opening signal is transmitted to the driving motor 410, so that the driving motor 410 drives the rotating rod 420 to rotate. When the second pushing rod 422 moves towards the transmission frame 610, the first pushing rod 421 and the second pushing rod 422 rotate synchronously, that is, the first pushing rod 421 rotates away from the valve 310, as Figure 3 、 Figure 4 shown, when the second pushing portion 424 contacts the second end 612 of the transmission frame 610, the distance between the first pushing portion 423 and the valve 310 is sufficient to open the valve 310.

[0076] When the second pushing part 424 abuts against the second end 612 of the transmission frame 610, in response to the driving motor 410 driving the second pushing part 424 to rotate towards the direction close to the transmission frame 610, the second end 612 of the transmission frame 610 will move towards the first end 611 of the transmission frame 610 under the push of the second pushing part 424. Further, the first end 611 will push the clamping part 520 to move away from the valve 310. When the clamping part 521 disengages from the clamping groove 311, under the action of the first elastic member 320, the valve 310 is switched from the closed position to the open position.

[0077] After the valve 310 completes the switching from the closed position to the open position, the driving motor 410 resets the rotating rod 420 to a position where there is no abutting action with the transmission frame 610 or the valve assembly 300. Without the external pushing action, the second elastic member 620 and the third elastic member 531 relax, and the transmission frame 610 will be reset under the combined action of the second elastic member 620 and the third elastic member 531.

[0078] The second aspect of the embodiments of the present disclosure provides a cleaning device 700, including the switch door structure described in the first aspect of the embodiments of the present disclosure. The cleaning device 700 has a base 710, and the floor washer is detachably cooperated with the base 710 to charge the cleaning device 700 or dump dirt and dust.

[0079] In some embodiments, the cleaning device 700 may be a floor washer, such as Figure 6 As shown, the automatic floor washer has a clean water tank 720 and a sewage tank 730. Among them, the sewage tank 730 may be provided with a switch door structure. When the cleaning device 700 is a floor washer, the container 100 is the sewage bucket of the floor washer.

[0080] Specifically, a switch door structure is arranged outside the sewage tank 730 and configured to discharge sewage from the sewage tank 730. During the user's use, the sewage in the sewage bucket 730 can be discharged at any time and anywhere, and the sewage can be directly discharged into the sewer pipeline. At the same time, under the drive of the driving motor 410, the valve 310 can be automatically opened, eliminating the need to manually open the lid of the sewage tank 730 and avoiding the user's hands or clothes from being contaminated.

[0081] Compared with the cleaning devices in the related art, the cleaning device 700 with a switch door structure provided by the present disclosure can discharge the sewage in the sewage bucket in any scenario when the floor washer is used alone. It has stronger operability and higher freedom of use in actual applications, and can significantly improve the user experience.

[0082] In some other embodiments, the cleaning device 700 may also be a floor sweeper or a vacuum cleaner. When the cleaning device 700 is a floor sweeper or a vacuum cleaner, the container 100 is the dust collection box of the floor sweeper or the vacuum cleaner. During the user's use, the dirt in the dust collection box of the floor sweeper or the vacuum cleaner can be automatically discharged through the switch door structure at any time and place, avoiding the contamination of the user's hands or clothes.

[0083] In addition, the cleaning device 700 described in the embodiments of the present disclosure may also be other cleaning devices 700 such as a vacuum and water suction machine, a hair dryer, a floor washing vehicle, a sofa cleaning device, a carpet machine, etc. that can utilize the switch door structure to realize the dumping of dirt.

[0084] In some embodiments, as Figure 7 shown, the cleaning device 700 has a base 710, and the floor washing machine is detachably cooperated with the base 710 to charge or dump dirt for the cleaning device 700.

[0085] Specifically, after the cleaning device 700 is cooperatively installed with the base 710, a dirt opening 701 is provided on one side of the base 710 facing the sewage tank 730 or the dust collection box. The driving motor 410 is used to control the valve 310 to switch between the open position and the closed position, so that the dirt in the sewage tank 730 or the dust collection box automatically discharges towards the dirt opening 701, and the dirt in the sewage tank 730 or the dust collection box enters the base station 710 through the dirt opening 701 to realize the automatic dumping of the dirt of the cleaning device 700.

[0086] For the specific structure, working principle, and beneficial effects of the switch door structure and the cleaning device provided by the embodiments of the present disclosure, reference may be made to the switch door structure and the cleaning device described in any of the above embodiments, which will not be elaborated here.

[0087] Finally, it should be noted that the embodiments in this specification are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments.
