DETAILED DESCRIPTION

[0031] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, and not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present disclosure.

[0032] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "the," and "the" 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. "A variety of" generally includes at least two, and other quantifiers are similar.

[0033] Throughout this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood broadly. For example, these terms can be fixed, removable, or integral; mechanical or electrical; and directly or indirectly through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure.

[0034] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0035] In the related art, the mainstream solution for dumping the sewage bucket or dust box of cleaning equipment currently on the market is manual dumping, but this solution has a poor user experience. The existing automatic sewage discharge solution requires the cleaning equipment host to be placed on the base station, and then the base station's automatic sewage discharge system cooperates to achieve sewage discharge, which has certain user usage restrictions. At the same time, after the cleaning equipment's dust is discharged to the base station, the dust inside the base station still needs to be discharged, adding a secondary dumping action, which affects the user experience.

[0036] Therefore, the present disclosure provides a switch door structure, including: a first fixed frame; a valve assembly, the valve assembly is rotatably connected to the first fixed frame, and the valve assembly has an open position and a closed position; a drive assembly, configured to provide a driving force to switch the valve assembly between the open position and the closed position.

[0037] The switch door structure provided by the present disclosure can be installed on cleaning equipment. Through the cooperation of the drive assembly and the valve assembly, the valve assembly automatically switches between an open position relative to the container opening and a closed position to achieve automatic sewage discharge. The cleaning equipment can automatically open the switch door structure to achieve automatic sewage discharge when connected to the base station, and can also achieve automatic sewage discharge when disconnected from the base station. Thus, the user can choose to actively control the valve assembly of the automatic switch door structure to open for sewage discharge in appropriate scenarios, effectively expanding the user's usage scenarios and improving the user experience.

[0038] In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0039] In some embodiments, as shown in FIG1 , the door opening and closing structure includes: a container 100, a valve assembly 300, and a drive assembly 400. The drive 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.

[0040] In the cleaning device 700 with the switchable door structure, a container 100 is provided for containing dust or sewage. The container 100 has an open mouth 101, which allows the internal space of the container 100 to communicate with the external environment.

[0041] A first fixing bracket 200 is provided on the outside of the container 100 for securing the container 100. The length of the first fixing bracket 200 is greater than the length of the container 100. A connecting hole 201 is provided at the end of the first fixing bracket 200 for rotatably connecting the valve assembly 300 to the first fixing bracket 200.

[0042] In some embodiments, the valve assembly 300 is rotatably connected to the first fixing frame 200. The valve assembly 300 has an open position that allows the interior space of the container 100 to communicate with the external environment, and a closed position that blocks the opening 101, thereby isolating the interior space of the container 100 from the external environment. During the rotation of the valve assembly 300, the valve assembly 300 can switch between the open position and the closed position.

[0043] Specifically, the valve assembly 300 includes a valve 310 and a first elastic member 320 .

[0044] The valve 310 is rotatably connected to the first mounting bracket 200 and is used to seal the open port 101, thereby isolating the interior of the container 100 from the external environment. The valve 310 is a plate-like structure, and a connecting shaft is provided at one end connected to the first mounting bracket 200. The connecting shaft is movably connected to the connecting hole 201, allowing the valve 310 to rotate relative to the first mounting bracket 200.

[0045] The first elastic member 320 is disposed between the valve 310 and the first fixing bracket 200. Specifically, the first elastic member 320 is sleeved on the outside of the connecting shaft, and always forces the valve 310 to move away from the opening 101, thereby driving the valve 310 to switch from the closed position to the open position when no external force is applied.

[0046] In some embodiments, the switch door structure further includes a driving assembly 400 , wherein 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.

[0047] Specifically, the drive assembly 400 includes a drive motor 410 and a rotating rod 420. The drive motor 410 is disposed outside the container 100 and is configured to drive the rotating rod 420 to rotate. The rotating rod 420 may be disposed on an outer wall of the drive motor 410. The rotating rod 420 rotates under the action of the drive motor 410 to push against the valve 310 to switch the valve 310 from the open position to the closed position, or to push against the transmission frame 610 to switch the valve 310 from the closed position to the open position.

[0048] In some embodiments, the rotating rod 420 includes at least 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 .

[0049] Furthermore, when the valve 310 is in an open state, the drive motor 410 can drive the first abutting rod 421 to rotate so that the first abutting portion 423 contacts the valve 310. Under the action of the drive motor 410, the valve 310 can be switched from an open position to a closed position under the action of the first abutting portion 423.

[0050] When the valve 310 is in the closed position, the driving motor 410 can drive the first pushing rod 421 to rotate so that the first pushing portion 423 is away from the valve 310. When there is no external force squeezing the valve 310, the first elastic member 320 can drive the valve 310 to switch from the closed position to the open position.

[0051] In some embodiments, the switch door structure further includes a clamping assembly 500. As shown in Figures 1 and 2, the clamping assembly 500 is disposed on a side of the container 100 away from the first fixing frame 200 and is configured to engage with the valve assembly 300 so that the valve assembly 300 is clamped to the opening 101.

[0052] Specifically, the clamping assembly 500 includes a second fixing frame 510 and a clamping member 520 .

[0053] As shown in Figure 2, the second fixing frame 510 is arranged on the side of the outside of the container 100 away from the first fixing frame 200, and a clamping member 520 is provided on the inner surface of the second fixing frame 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 to clamp with the plane of the valve 310 when the valve 310 is in the closed position.

[0054] Furthermore, the free end of the clamping member 520 extends toward the first elastic member 320, and a clamping portion 521 is provided at the free end of the clamping member 520. The side of the clamping portion 521 away from the open port 101 is constructed as an inclined structure, and the side of the clamping portion 521 facing the open port 101 is constructed as a flat surface, which is used to clamp with the valve 310 to stably keep the valve 310 in the closed position.

[0055] In some embodiments, a snap-in groove 311 is provided at the free end of the valve 310 away from the open port 101. The snap-in groove 311 is constructed as a groove suitable for snapping with the snap-in portion 521, and is used to snap-in with the snap-in portion 521 to stabilize the valve 310 in the closed position.

[0056] Specifically, as shown in Figure 3, 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 suitable for pushing the valve 310, so that the valve 310 and the inclined surface of the clamping portion 521 are stopped. Furthermore, under the action of the drive motor 410, the free end of the valve 310 can be pushed against the clamping portion 521 along the inclined surface structure, so that the clamping portion 521 moves in a direction away from the valve 310. The free end of the valve 310 is suitable for moving along the edge of the clamping portion 521 toward the closed position. 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 is in the closed position, as shown in Figure 4.

[0057] In some embodiments, as shown in Figures 4 and 5, a limiting portion 530 is provided on one side of the inner wall of the second fixing frame 510, directly opposite the clamping member 520 and the transmission frame 610. A gap is defined between the limiting portion 530 and the clamping member 520. This gap allows the clamping member 520 and the transmission frame 610 to move in the same direction, allowing the clamping portion 521 to engage with or disengage from the clamping groove 311. The limiting portion 530 is used to limit the position of the clamping member 520, effectively preventing the clamping member 520 from breaking due to excessive bending.

[0058] Specifically, the limiting portion 530 includes a third elastic member 531. When the clamping 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 clamping member 520 away from the container 100 will abut against the third elastic member 531. The abutment of the third elastic member 531 prevents the clamping member 520 from further moving or bending toward the side away from the container 100, thereby preventing the clamping member 520 from excessive bending and causing breakage.

[0059] Furthermore, since the third elastic member 531 has a certain elastic force, after the transmission frame 610 cancels the pushing force on the clamping member 520 , the third elastic member 531 can be used to assist the clamping member 520 in resetting.

[0060] In some embodiments, a gasket 312 is provided on a side of the valve 310 facing the open port 101 , and the gasket 312 can be used to seal the open port 101 .

[0061] In some embodiments, the door opening and closing structure further includes a transmission assembly 600. As shown in Figures 2, 4, and 5, the transmission assembly 600 is disposed between the drive assembly 400 and the clamping assembly 500. Under the action of the drive assembly 400, the transmission assembly 600 is configured to push against the clamping assembly 500, causing the clamping member 520 to move 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 cause the clamping assembly 500 to release the valve assembly 300.

[0062] 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, allowing horizontal movement relative to the container 100. The transmission frame 610 has a first end 611 distal from the drive assembly 400 and a second end 612 adjacent to the drive assembly 400.

[0063] Specifically, when the valve 310 is in the closed position, if the transmission frame 610 is moved from the second end 612 toward the first end 611, the first end 611 will push against the engaging member 520, causing the engaging portion 521 to disengage from the engaging groove 311. Furthermore, under the action of the first elastic member 320, the valve 310 switches from the closed position to the open position.

[0064] 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, causing the second end 612 to tend to move away from the container 100.

[0065] Specifically, when the valve 310 switches from the closed position to the open position, the second end 612 tends to move away from the container 100 due to the arrangement of the second elastic member 620. Therefore, after the engaging portion 521 is released from the engaging groove 311, the transmission assembly 600 moves back toward the second end 612 under the action of the second elastic member 620. Furthermore, the third elastic member 531 assists the engaging portion 520 in returning to its original position.

[0066] In some embodiments, the rotating rod 420 may include a first pushing rod 421 and a second pushing rod 422, as shown in Figures 1 and 4. The first pushing rod 421 is provided with a first pushing portion 423 at its end for contacting and pushing the valve 310 to switch the valve 310 from an open position to a closed position.

[0067] The second abutting portion 424 is provided at the end of the second abutting rod 422. The second abutting portion 424 is configured to push the second end 612 of the transmission frame 610. In response to the second abutting 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, moving the clamping assembly 500 away from the opening 101, thereby switching the valve 310 from the closed position to the open position.

[0068] In some embodiments, the first pushing rod 421 and the second pushing rod 422 rotate synchronously.

[0069] When the valve 310 needs to be switched from the open position to the closed position, a closing signal is transmitted to the drive motor 410, causing the drive motor 410 to rotate the rotating rod 420. When the first push rod 421 rotates toward the valve 310, the second push rod 422 moves away from the transmission frame 610.

[0070] When the first abutting portion 423 pushes the valve 310 and thereby abuts against the inclined surface of the clamping portion 521 on the side away from the open port 101, in response to the drive motor 410 driving the first abutting portion 423 to move toward the closed position, the free end of the valve 310 is adapted to move toward the closed position along the inclined surface of the clamping portion 521. Under the pressure of the valve 310, the clamping portion 521 moves in a direction 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 point, the valve 310 completes the switch from the open position to the closed position. In the absence of external force, the valve 310 is usually in the closed position.

[0071] When the valve 310 needs to be switched from a closed position to an open position, an opening signal is transmitted to the drive motor 410, causing the drive motor 410 to rotate the rotating rod 420. When the second abutting rod 422 moves toward the transmission frame 610, the first abutting rod 421 rotates synchronously with the second abutting rod 422, i.e., the first abutting rod 421 rotates away from the valve 310. As shown in Figures 3 and 4, when the second abutting portion 424 contacts the second end 612 of the transmission frame 610, the distance between the first abutting portion 423 and the valve 310 is sufficient to open the valve 310.

[0072] When the second abutting portion 424 abuts the second end 612 of the transmission frame 610, in response to the drive motor 410 driving the second abutting portion 424 to rotate toward the transmission frame 610, the second end 612 of the transmission frame 610, pushed by the second abutting portion 424, moves toward the first end 611 of the transmission frame 610. Furthermore, the first end 611 pushes the engaging member 520 away from the valve 310. When the engaging portion 521 disengages from the engaging groove 311, the valve 310 switches from a closed position to an open position under the action of the first elastic member 320.

[0073] After the valve 310 switches from the closed position to the open position, the drive motor 410 returns the rotating rod 420 to a position where it no longer pushes against the transmission frame 610 or the valve assembly 300. Without external force, the second elastic member 620 and the third elastic member 531 relax, and the transmission frame 610 returns to its original position under the combined action of the second elastic member 620 and the third elastic member 531.

[0074] The second aspect of the present disclosure provides a cleaning device 700, comprising the switch door structure described in the first aspect of the present disclosure. The cleaning device 700 has a base 710, and the cleaning device 700 can be detachably matched with the base 710 to charge the cleaning device 700 or dump dust.

[0075] In some embodiments, the cleaning device 700 can be a floor scrubber. As shown in FIG6 , the automatic floor scrubber has a clean water tank 720 and a dirty water tank 730 . The dirty water tank 730 can be provided with a door. When the cleaning device 700 is a floor scrubber, the container 100 is the dirty water tank of the floor scrubber.

[0076] Specifically, the sewage tank 730 is equipped with an external door structure configured to discharge sewage from the tank 730. During use, the user can drain the sewage from the tank 730 at any time and place, directly into the sewer line. Simultaneously, the valve 310 is automatically opened by the drive motor 410, eliminating the need to manually open the lid of the sewage tank 730 and preventing contamination of the user's hands or clothing.

[0077] Compared to cleaning devices in related technologies, the cleaning device 700 with a switchable door structure provided by the present disclosure can discharge the sewage in the sewage tank in any scenario when the floor scrubber is used alone. In practical applications, it is more operable and has greater freedom of use, which can significantly improve the user experience.

[0078] In other embodiments, the cleaning device 700 may also be a sweeper or a vacuum cleaner. When the cleaning device 700 is a sweeper or a vacuum cleaner, the container 100 is a dust box of the sweeper or vacuum cleaner. During use, the dust in the dust box of the sweeper or vacuum cleaner can be automatically discharged through the door structure at any time, preventing contamination of the user's hands or clothing.

[0079] In addition, the cleaning device 700 described in the embodiment of the present disclosure can also be a vacuum cleaner, a dry air machine, a floor scrubber, a sofa cleaning device, a carpet machine, or any other cleaning device 700 that can use a switch door structure to dump dust.

[0080] In some embodiments, as shown in FIG7 , the cleaning device 700 has a base 710. The cleaning device 700 can be detachably matched with the base 710 to charge the cleaning device 700 or dump dirt and dust.

[0081] Specifically, after the cleaning device 700 is mounted on the base 710, a dust opening 701 is provided on the side of the base 710 facing the sewage tank 730 or dust collection box. The drive motor 410 controls the valve 310 to switch between an open and closed position, so that dust in the sewage tank 730 or dust collection box is automatically discharged toward the dust opening 701. Dust in the sewage tank 730 or dust collection box enters the base 710 through the dust opening 701, thereby automatically dumping dust from the cleaning device 700.

[0082] The specific structure, working principle, and beneficial effects of the door opening and closing structure and cleaning equipment provided by the embodiments of the present disclosure can refer to the door opening and closing structure and cleaning equipment described in any of the above embodiments, and will not be repeated here.

[0083] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. References to the common and similar parts between the various embodiments will be sufficient. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, their descriptions are relatively simple; for relevant details, refer to the descriptions of the methods.

[0084] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
