Description

Technical Field

[0001] The present disclosure relates to the field of cleaning equipment, and more specifically, to a cleaning equipment and a sewage bucket. Background Art

[0002] Environmental sanitation is a crucial factor affecting the quality of life. Consequently, as people's expectations for quality of life continue to rise, so too do their demands for environmental sanitation. Consequently, a wide range of floor cleaning equipment has emerged, including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that cleans the floor while simultaneously sucking up wastewater and removing it from the site.

[0003] Existing floor scrubbers typically use a fan unit to create negative pressure within the wastewater bucket, thereby drawing dirt from the work surface into the bucket. However, as the fan unit operates, some moisture from the dirt can enter the unit along with the airflow. This water ingress can easily cause the fan unit to malfunction, affecting the proper functioning of the cleaning equipment and, in turn, the user experience. This is especially true when the scrubber's body is lying flat relative to the brush, and the water level in the wastewater bucket is too close to the suction port, making it more likely that the fan unit will absorb moisture and be damaged.

[0004] Another problem faced by existing floor scrubbers that are not easy to take in water when lying flat is that the orientation of the sewage tank changes in the lying state, which makes the effective sewage holding volume of the sewage tank limited under the premise of no water taking in. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present disclosure provides a cleaning device and a sewage bucket.

[0006] According to a first aspect of the present disclosure, a cleaning device is provided, comprising a body and a sewage bucket disposed on the body; wherein the sewage bucket comprises:

[0007] A barrel body, the barrel body having an inner cavity and a sewage inlet pipe;

[0008] a barrel cover configured to be detachably fastened to the barrel body; the barrel cover being provided with a partition assembly extending into the inner cavity; the inner cavity comprising a first chamber and a second chamber arranged front to back along the barrel body by the partition assembly, wherein the sewage inlet pipe is located in the first chamber, and the barrel cover is provided with an air outlet located in the second chamber;

[0009] A transfer channel is provided in the partition assembly, an inlet end of the transfer channel is communicated with an outlet of the sewage inlet pipe, and an outlet end of the transfer channel is provided in the second chamber.

[0010] During the operation of the cleaning device disclosed herein, the dirt on the working surface can enter the inlet end of the transfer channel from the outlet of the sewage inlet pipe located in the first chamber along the sewage inlet pipe under the action of the negative pressure generated by the fan unit, and then move along the transfer channel and finally fall into the second chamber, and the air flow will flow from the air outlet arranged above the second chamber near the barrel cover to the fan unit.

[0011] When the cleaning device of the present disclosure is in a normal state, the sewage is mainly located below the inner cavity of the sewage bucket, away from the air outlet at the top, making it difficult for the sewage to enter the fan unit. When the cleaning device of the present disclosure is in a tilted or flat state, the body of the cleaning device tilts rearward, so that the first chamber is located obliquely below or directly below the second chamber. After the sewage falls into the second chamber, it flows into the first chamber, thus being located below the entire sewage bucket. The partition assembly can suppress the splash generated during the movement of the cleaning device. By separating the air outlet in the second chamber from the sewage stored in the first chamber, the sewage in the first chamber is prevented from directly passing over the partition assembly and entering the second chamber in the flat state. The sewage is difficult to enter the second chamber, thereby preventing the sewage from flowing along the air outlet at the top of the second chamber into the fan unit, avoiding malfunction of the fan unit due to water ingress, effectively extending the service life of the cleaning device of the present disclosure, and thereby improving the user experience. At the same time, the space in the second chamber below the partition assembly can be fully utilized to accommodate the sewage in the flat state, thereby expanding the effective volume of the sewage bucket in the flat state without having to worry about the location of the sewage inlet pipe outlet.

[0012] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments of the present disclosure with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints, but also several sub-ranges contained therein.

[0028] The present disclosure provides a cleaning device, which is used to clean work surfaces such as floors and carpets. The cleaning device includes a body and a sewage bucket arranged on the body; wherein the sewage bucket includes a barrel body and a barrel cover, the barrel body has an inner cavity and a sewage inlet pipe; the barrel cover is constructed to be snapped onto the barrel body in a detachable manner; a partition component extending into the inner cavity is provided on the barrel cover; a part of the inner cavity corresponding to the partition component is divided by the partition component into a first chamber and a second chamber separated from each other front and back; a transfer channel is provided in the partition component, the inlet end of the transfer channel is connected to the outlet of the sewage inlet pipe arranged in the first chamber, and the outlet end of the transfer channel is provided in the second chamber.

[0029] It can be understood that the cleaning equipment disclosed herein also includes a fan unit, which is connected to the air outlet and can form negative pressure in the inner cavity of the sewage bucket through airflow; a sewage suction pipe is provided at the bottom of the fuselage, and the bottom opening of the sewage inlet pipe of the sewage bucket is connected to the sewage suction pipe.

[0030] Therefore, during the operation of the cleaning device disclosed herein, the dirt on the working surface can enter the inlet end of the transfer channel from the outlet of the sewage inlet pipe located in the first chamber along the sewage inlet pipe under the action of the negative pressure generated by the fan unit, and then move along the transfer channel and finally fall into the second chamber, and the air flow will flow from the air outlet arranged above the second chamber near the barrel cover to the fan unit.

[0031] When the cleaning device of the present disclosure is in a normal state, the sewage is mainly located below the inner cavity of the sewage bucket, away from the air outlet at the top, making it difficult for the sewage to enter the fan unit. When the cleaning device of the present disclosure is in a tilted or flat state, the body of the cleaning device tilts rearward, so that the first chamber is located obliquely below or directly below the second chamber. After the sewage falls into the second chamber, it flows into the first chamber, thus being located below the entire sewage bucket. The partition assembly can suppress the splash generated during the movement of the cleaning device. By separating the air outlet in the second chamber from the sewage stored in the first chamber, the sewage in the first chamber is prevented from directly passing over the partition assembly and entering the second chamber in the flat state. The sewage is difficult to enter the second chamber, thereby preventing the sewage from flowing along the air outlet at the top of the second chamber into the fan unit, avoiding malfunction of the fan unit due to water ingress, effectively extending the service life of the cleaning device of the present disclosure, and thereby improving the user experience. At the same time, the space in the second chamber below the partition assembly can be fully utilized to accommodate the sewage in the flat state, thereby expanding the effective volume of the sewage bucket in the flat state without having to worry about the location of the sewage inlet pipe outlet. The switching channel is connected to the outlet of the sewage inlet pipe, so that even if the second chamber is filled with sewage in a flat state, the sewage inlet pipe outlet will not be unable to work due to being submerged in sewage.

[0032] For ease of understanding, refer to Figures 1 to 8 , the specific structure and working principle of the cleaning device disclosed in the present invention are explained in detail with reference to an embodiment.

[0033] like Figure 1 and Figure 2As shown, the present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. The cleaning device includes a body and a wastewater bucket mounted on the body to hold wastewater drawn from the work surface during cleaning. The wastewater bucket includes a body 20 and a lid 10. The body 20 has an inner cavity 21 and a wastewater inlet pipe 22. The lid 10 is configured to removably snap onto the body 20. A partition assembly 30 is provided on the lid 10, extending into the inner cavity 21. Both sides of the partition assembly 30 abut against the inner wall of the inner cavity 21, thereby separating the inner cavity 21 corresponding to the partition assembly 30 into a first chamber 211 and a second chamber 212, each isolated from the front and back. For example, if the cleaning device is a handheld floor scrubber, the side of the cleaning device closest to the user is defined as the rear side, and the side away from the user is defined as the front side. The user can hold the cleaning device and move it back and forth across the work surface to clean the work surface. The first chamber 211 and the second chamber 212 are arranged front to back along the body 20. The present disclosure does not limit the front-to-back order of the first chamber 211 and the second chamber 212, but only limits the two chambers to be arranged front-to-back along the barrel body 20. In a specific embodiment of the present disclosure, the sewage tank is disposed on the front side of the body, and the second chamber 212 is located on the front side of the barrel body 20 relative to the first chamber 211.

[0034] A transfer channel 40 is provided within the partition assembly 30. The inlet end of the transfer channel 40 communicates with the outlet of the sewage inlet pipe 22 disposed within the first chamber 211, and the outlet end of the transfer channel 40 is disposed within the second chamber 212. This structural design allows the transfer channel 40 to be concealed within the partition assembly 30, thereby reducing the space occupied by the transfer channel 40.

[0035] Specifically, the end of the transfer channel 40 away from the barrel cover 10 is constructed to extend axially along the barrel body 20, and the end of the transfer channel 40 adjacent to the barrel cover 10 is constructed to extend into the first chamber 211 and be connected with the sewage inlet pipe 22 located in the first chamber 211; an air outlet 34 is provided at the bottom of the barrel cover 10, and the air outlet 34 is constructed to be located in the second chamber 212; in the cleaning equipment, the side where the air outlet 34 is located is the front side, and the side where the sewage inlet pipe 22 is located is the rear side, that is, the first chamber 211 is located at the rear part of the barrel body 20 relative to the second chamber 212, and the air outlet 34 is opened forward.

[0036] like Figure 6 As shown, in the upright state and the tilted state, the outlet of the transfer channel 40 extends roughly along the axial direction of the sewage bucket away from the bucket cover 10, as shown in FIG. Figure 7 As shown, in the lying-flat state, the outlet direction of the transfer channel 40 is toward the front side, so as to adjust the cross-sectional area of ​​the outlet of the transfer channel 40 in different fuselage states under different use states.

[0037] It can be understood that the cleaning equipment disclosed herein also includes a fan unit, which is connected to the air outlet 34 through the filter installation port 11 on the barrel cover 10, and can form negative pressure in the inner cavity 21 of the sewage barrel through airflow; a sewage suction pipe is provided at the bottom of the fuselage, and the bottom opening of the sewage inlet pipe 22 of the sewage barrel is connected to the sewage suction pipe.

[0038] Therefore, during the operation of the cleaning device disclosed herein, the dirt on the working surface can enter the inlet end of the transfer channel 40 from the outlet of the sewage inlet pipe 22 located in the first chamber 211 along the sewage inlet pipe 22 under the action of the negative pressure generated by the fan unit, and then move along the transfer channel 40 and finally fall into the second chamber 212, and the air flow will flow from the air outlet 34 arranged above the second chamber 212 near the barrel cover 10 to the fan unit.

[0039] like Figure 6 As shown, when the cleaning device of the present disclosure is in a normal state, the sewage is mainly located below the inner cavity 21 of the sewage bucket, away from the air outlet 34 above, and the sewage is not easy to enter the fan unit; Figure 7 As shown, when the cleaning device of the present invention is in a tilted or lying state, the body of the cleaning device will tilt toward the rear, so that the first chamber 211 will be located obliquely below or directly below the second chamber 212. After the sewage falls into the second chamber 212, it will flow into the first chamber 211, and thus be located below the entire sewage bucket. The partition component 30 can suppress the splashes generated during the movement of the cleaning device, and by separating the air outlet 34 located in the second chamber 212 and the sewage stored in the first chamber 211, it prevents the sewage located in the first chamber 211 in the lying state from directly crossing the partition component 30 and entering the second chamber 212. It is difficult for the sewage to enter the second chamber 212, thereby preventing the sewage from flowing along the air outlet 34 at the top of the second chamber 212 to the fan unit, thereby avoiding the fan unit from malfunctioning due to water ingress, effectively extending the service life of the cleaning device of the present invention, and thereby improving the user experience.

[0040] like Figure 1 As shown, in one embodiment of the present disclosure, the transfer channel 40 includes a first channel 41 and a second channel 42 that are interconnected. The first channel 41 is configured to extend in the front-to-back direction and dock with the outlet of the sewage inlet pipe 22. The second channel 42 is located in the partition assembly 30 and extends in a direction away from the barrel cover 10.

[0041] Specifically, the first channel 41 extends approximately in the front-to-back direction near the barrel cover 10, and has an entrance that opens toward the bottom of the barrel body 20 to connect with the sewage inlet pipe 22. The second channel 42 can be located on one side of the second chamber 212, or can be arranged between the first chamber 211 and the second chamber 212. The sewage in the sewage inlet pipe 22 is constructed to flow to the second chamber 212 through the first channel 41 and the second channel 42. During the operation of the cleaning device disclosed herein, the dirt on the working surface can enter the first channel 41 along the sewage inlet pipe 22 under the action of the negative pressure generated by the fan unit, and flow from the first chamber 211 to the second channel 42 along the first channel 41, and flow in the second channel 42 along the axial direction of the sewage barrel toward the side away from the barrel cover 10, so that when the sewage flows out of the second channel 42, it can flow toward the bottom of the barrel body 20, away from the air outlet 34 arranged above the second chamber 212 near the barrel cover 10, and try to avoid the sewage from entering the air outlet 34. Through the above arrangement, the dirt that would have been sucked into the first chamber 211 by the sewage inlet pipe 22 is transferred to the second chamber 212 on the front side of the partition assembly 30 through the transfer channel 40. This avoids the situation in which, when lying flat, the outlet of the sewage inlet pipe 22 is exposed in the second chamber 212, causing the sewage to flood the outlet of the sewage inlet pipe 22 and prevent the sewage from continuing to be sucked out. This causes the sewage to stop sucking before the sewage bucket is full of water, thereby reducing the utilization rate of the sewage bucket volume. At the same time, by extending the second channel 42 axially away from the air outlet 34 located above it, the dirt can be controlled to be ejected from the second channel 42 in a preset direction away from the air outlet 34. The axial length of the second channel 42 can also prevent the ejected dirt from splashing near the air outlet 34, causing the fan unit to be damaged by inhaling water vapor.

[0042] In one embodiment of the present disclosure, a partition assembly 30 includes a first half-partition 31 and a second half-partition 32 that are movable relative to each other. The first half-partition 31 or the second half-partition 32 is configured to switch between a first state and a second state. When in the first state, the first half-partition 31 or the second half-partition 32 is configured to cooperate to form a transfer channel 40. When in the second state, the first half-partition 31 or the second half-partition 32 is configured to move away from the other half-partition to open the transfer channel 40. The first and second half-partitions 31 and 32 can be pivoted or slid open to facilitate cleaning of dirt clogged in the transfer channel 40.

[0043] Specifically, Figures 1 to 3As shown, in one embodiment of the present disclosure, the partition assembly 30 includes a first half partition 31 disposed on the tub cover 10. One end of the first half partition 31 is fixedly connected to the tub cover 10, and the other end is pivotally connected to a second half partition 32. The second half partition 32 is configured to move between a first state and a second state. In the first state, the second half partition 32 is configured to be combined with the first half partition 31 to form a transfer channel 40. In the second state, the second half partition 32 is configured to pivot relative to the first half partition 31 to open the transfer channel 40.

[0044] Since the second half partition 32 can move between the first state and the second state, in the working state of the cleaning device disclosed in the present invention, the second half partition 32 is in the first state and can form a transfer channel 40 with the first half partition 31, and the sewage can flow normally along the transfer channel 40; and when the user needs to clean the inside of the sewage bucket, the bucket cover 10 can be removed from the barrel body 20, and the second half partition 32 can be rotated to the second state, thereby opening the transfer channel 40, making it easier for the user to clean the dirt inside the transfer channel 40.

[0045] The first channel 41 can be entirely provided on the second half partition 32 , the rear wall 321 of the second channel 42 is provided on the second half partition 32 , the front wall 312 of the second channel 42 is provided on the first half partition 31 , and the front wall 312 and the rear wall 321 together define the second channel 42 .

[0046] Specifically, such as Figure 1 and Figure 3 As shown, in one embodiment of the present disclosure, the second half-partition 32 includes an integrally connected rear wall 321 and a sewage pipe 322. The sewage pipe 322 is located above the rear wall 321 and upstream of the rear wall 321 in the dirt recovery flow path. The sewage pipe 322 is configured to enclose a first channel 41. The rear wall 321 is configured to enclose a second channel 42 with the first half-partition 31 when in a first state, and to open the second channel 42 when in a second state. Specifically, the sewage pipe 322 can penetrate the rear wall 321, forming the first channel 41 that penetrates the rear wall 321. That is, the first channel 41 is integrally provided on the second half-partition 32, while the rear wall 321 and the first half-partition 31 enclose the second channel 42.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the first half partition 31 includes a front wall 312 . The front wall 312 of the second channel 42 is disposed on the first half partition 31 . The front wall 312 and the rear wall 321 together define the second channel 42 .

[0048] The front wall 312 extends in the transverse direction to form a first connection portion 3111 and a second connection portion 3112 abutting against the inner cavity 21 . The first connection portion 3111 , the second connection portion 3112 , the front wall 312 and the rear wall 321 together isolate and form the first chamber 211 and the second chamber 212 .

[0049] Specifically, the second half partition 32 is rotatably connected to the lower ends of the first connecting part 3111 and the second connecting part 3112, and the rear wall 321 is constructed to separate the corresponding parts of the barrel body 20 into a first chamber 211 and a second chamber 212 that are isolated from each other together with the first connecting part 3111 and the second connecting part 3112 when in the first position, and form a second channel 42 between the front wall 312, and the air outlet 34 is located on the side of the front wall 312 away from the second channel 42. In this way, when the rear wall 321 is in the first state, it can not only work together with the first connecting part 3111 and the second connecting part 3112 to separate the corresponding parts of the barrel body 20 into the first chamber 211 and the second chamber 212 isolated from each other, but can also form a second channel 42 with the front wall 312, without the need to set up a corresponding structure separately, thereby simplifying the overall structure; and because the air outlet 34 is located on the side away from the second channel 42 relative to the front wall 312, during the flow of sewage along the second channel 42, the front wall 312 can block the sewage from flowing toward the air outlet 34, ensuring that the sewage can only flow along the axial direction of the sewage bucket toward the side away from the barrel cover 10, and try to avoid sewage from entering the air outlet 34.

[0050] like Figure 1 As shown, in one embodiment of the present disclosure, the front wall 312 is constructed to extend downward from the barrel cover 10 to a position lower than the outlet 3221 of the sewage pipe 322; since the front wall 312 extends downward from the barrel cover 10 to a position lower than the outlet 3221 of the sewage pipe 322, the second channel 42 can extend a certain distance along the axial direction of the sewage barrel toward a side away from the barrel cover 10, so that after the sewage outlet flows out of the second channel 42, it can be as far away from the air outlet 34 as possible.

[0051] like Figure 1 As shown, in one embodiment of the present disclosure, the second channel 42 is provided with an anti-backflow plate 3211 adjacent to the first channel 41 ; the anti-backflow plate 3211 extends in a direction away from the first channel 41 .

[0052] Specifically, the rear wall 321 is provided with an anti-backflow plate 3211 in the transfer channel 40. The anti-backflow plate 3211 is constructed to be located below the outlet 3221 when in the first state, and extends along the extension direction of the rear wall 321 to form an anti-backflow groove 3212 between the rear wall 321.

[0053] In this way, during the operation of the cleaning device of the present invention, especially during the cleaning operation when the body is in a flat position, the sewage in the sewage bucket fluctuates back and forth with the movement of the cleaning device, and flows back to the second channel 42 along the bottom opening of the second channel 42. Since the anti-backflow plate 3211 is located below the outlet 3221 and extends along the extension direction of the rear wall 321 to form an anti-backflow groove 3212 between the rear wall 321, most of the sewage will enter the anti-backflow groove 3212, thereby preventing the sewage from flowing back to the first channel 41 and flowing back to the work surface along the sewage suction pipe, thereby effectively improving the user experience.

[0054] Further, such as Figure 1 As shown, in one embodiment of the present disclosure, a connecting hole 3213 may be provided on the second channel 42 at a position corresponding to the anti-backflow plate 3211, and the first chamber 211 and the second chamber 212 are connected through the connecting hole 3213. Specifically, the connecting hole 3213 may be provided at the lower edge of the rear wall 321. After the sewage enters the anti-backflow groove 3212, it can flow along the connecting hole 3213 into the first chamber 211, thereby further ensuring that the sewage does not flow back into the first channel 41. At the same time, when no diversion occurs, for example, when the fuselage is in a tilted state, the connecting hole 3213 connects the first and second chambers 211 and 212 in the front-to-back direction, thereby utilizing the gas space of the second chamber 212. This avoids the inability to utilize the space of the second chamber 212, resulting in insufficient space volume in the first chamber 211, causing the air flow speed in the first chamber 211 to be too fast, causing the motor to inhale water vapor.

[0055] like Figure 1 、 Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the front wall 312 is provided with water-retaining ribs 3121 on its inner wall surface. Specifically, the water-retaining ribs 3121 are provided on the wall surface of the front wall 312 adjacent to the outlet 3221 of the sewage pipe 322. The water-retaining ribs 3121 are configured to reduce the flow velocity of the sewage as it flows through the water-retaining ribs 3121. By providing the water-retaining ribs 3121 on the wall surface of the water plate adjacent to the outlet 3221 of the sewage pipe 322, the flow velocity of the sewage in the second channel 42 can be effectively reduced, thereby minimizing the degree of splashing caused by the sewage striking the barrel wall or other parts after flowing out of the second channel 42, and preventing the splashing from being too high and causing the sewage to be too close to the air outlet 34.

[0056] Specifically, such as Figure 4As shown, in one embodiment of the present disclosure, the water-retaining rib 3121 includes a first rib 31211, which includes two ribs extending obliquely from top to bottom toward both sides of the front wall 312. The first rib 31211 can be arranged directly opposite the outlet 3221. The first rib 31211 can effectively reduce the flow rate of dirt. Moreover, because the first rib 31211 includes two ribs with interconnected tops and extending obliquely from top to bottom toward both sides of the front wall 312, when the sewage in the sewage bucket rises and falls with the movement of the cleaning equipment and flows back into the second channel 42 along the bottom opening of the second channel 42, the first rib 31211 can also effectively prevent the sewage from flowing back along the first rib 31211, thereby further preventing the sewage from flowing back into the first channel 41.

[0057] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the water retaining rib 3121 also includes a second rib 31212 arranged on the front wall 312 at a position lower than the first rib 31211, and the second rib 31212 is constructed to extend in an axial direction perpendicular to the barrel body 20, and in the projection of the cross section of the sewage bucket, the first rib 31211 and the second rib 31212 cover the wall surface of the water retaining member on the side of the second channel 42.

[0058] In this way, the second ribs 31212 can effectively reduce the flow speed of dirt. Since the second ribs 31212 extend in an axial direction perpendicular to the barrel body 20, the effect of reducing the flow speed of dirt is better.

[0059] Furthermore, because the first ribs 31211 and the second ribs 31212 cover the wall of the water retaining member on the side of the second channel 42 in the projection of the cross-section of the sewage bucket, when the sewage in the sewage bucket rises and falls with the movement of the cleaning equipment and flows back into the second channel 42 along the bottom opening of the second channel 42, the first ribs 31211 and the second ribs 31212 can prevent the sewage from flowing back along the wall of the water retaining member on the side of the second channel 42, further preventing the sewage from flowing back into the first channel 41. At the same time, the herringbone-shaped first ribs 31211 can guide the flowing sewage to the second ribs 31212 on both sides of its bottom for a second blockage, reducing the flow rate of the sewage. At the same time, the herringbone shape of the first ribs 31211 can prevent the sewage from getting caught on the first ribs 31211.

[0060] like Figure 1 and Figure 3As shown, in one embodiment of the present disclosure, the second half partition 32 also includes a solid-liquid separation plate 33 arranged at the bottom of the rear wall 321, the solid-liquid separation plate 33 is constructed to be perpendicular to the rear wall 321, and is provided with a solid-liquid separation hole; the inner cavity 21 forms a first chamber 211 and a second chamber 212 above the solid-liquid separation plate 33, and forms a third chamber 213 below the solid-liquid separation plate 33, and the third chamber 213 can be respectively connected to the first chamber 211 and the second chamber 212 through the solid-liquid separation hole.

[0061] Specifically, when the solid-liquid separation plate 33 and the rear wall 321 are in the first position, they divide the inner cavity 21 into a first chamber 211 and a second chamber 212 arranged front to back, and a third chamber 213 located below the first and second chambers 211 and 212. The first chamber 211 and the second chamber 212 are both located above the solid-liquid separation plate 33 and on the front and rear sides of the rear wall 321, respectively. The third chamber 213 is located below the solid-liquid separation plate 33 and is connected to the first chamber 211 and the second chamber 212 through the solid-liquid separation holes. The third chamber 213 is used to receive and store sewage separated by the solid-liquid separation plate 33. When the cleaning device is in an upright or tilted position, the sewage is mainly stored in the third chamber 213. The first chamber 211 can store some sewage when the body is tilted at a large angle. When the body is lying flat, the sewage is stored in both the first chamber 211 and the third chamber 213.

[0062] In this way, when the cleaning equipment disclosed herein is in a normal state, that is, the body is in an upright or slightly tilted state, after the sewage flows from the second channel 42 into the second chamber 212, it will continue to flow downward to the third chamber 213 below the second chamber 212 under the action of its own gravity, away from the air outlet 34 above, and the solid waste in the sewage will be intercepted on the solid-liquid separation plate 33.

[0063] When the cleaning device of the present invention is in a tilted state at a large angle or lying flat, it will tilt toward the rear, so that the first chamber 211 will be located obliquely below or directly below the second chamber 212. After the sewage falls into the third chamber 213, part of it will flow into the first chamber 211. In this way, the sewage will be below the entire sewage bucket. The partition component 30 can inhibit the movement of the cleaning device, and it is difficult for the sewage to enter the second chamber 212, thereby preventing the sewage from flowing along the air outlet 34 at the top of the second chamber 212 to the fan unit, avoiding the fan unit from malfunctioning due to water ingress, effectively extending the service life of the cleaning device of the present invention, and thus improving the user experience.

[0064] like Figure 1 、 Figure 2 and Figure 8As shown, in one embodiment of the present disclosure, the bottom edge of the front wall 312 is constructed with both ends recessed upward relative to the middle to form a ventilation notch 3122. The highest end of the ventilation notch 3122 and the solid-liquid separation plate 33 are configured to enclose a flat vent 3123. The area of ​​the flat vent 3123 is configured to be larger than the cross-sectional area of ​​the second channel 42 perpendicular to the axial direction. Because the ends of the front wall 312 are recessed upward relative to the middle, that is, the middle portion extends downward relative to the ends, the cleaning equipment can be kept in normal working condition. The middle portion of the front wall 312 blocks the flow of sewage toward the air outlet 34, that is, the middle portion of the front wall 312 increases the axial distance between the outlet of the second channel 42 and the air outlet 34.

[0065] It is understandable that if Figure 7 As shown, when the cleaning device of the present disclosure is working in a lying state, the airflow flows along the horizontal second channel 42, reaches the lying vent 3123, flows upward, and then flows horizontally to the air outlet 34. In the direction of dirt flow, since the cross-sectional area of ​​the lying vent 3123 formed by the highest end of the ventilation gap 3122 and the solid-liquid separation plate 33 is larger than the cross-sectional area of ​​the second channel 42, the characteristic that the gas flow rate will decrease when entering the channel with a large cross-sectional area from a channel with a small cross-sectional area is utilized to ensure that the gas flow rate decreases due to the change in cross-sectional area after flowing from the second channel 42 to the lying vent 3123, so that the water vapor carried in the airflow can be retained as much as possible below the second chamber 212 under the action of its own gravity, and will not enter the fan unit with the airflow.

[0066] It is understandable that if Figure 6 and Figure 7 As shown, the transfer channel 40 switches between different outlets when the fuselage is in the flat and non-flat positions to prevent moisture from entering the fan unit. Specifically, the outlet of the transfer channel 40 has a first outlet cross-section when the fuselage is in the flat operating mode and a second outlet cross-section when the fuselage is in the non-flat operating mode. The first outlet cross-section in the flat state is horizontally defined by the partition assembly 30 and the solid-liquid separation plate 33. The second outlet cross-section in the upright state is also horizontally defined by the partition assembly 30, and the first outlet cross-section has a larger area than the second outlet cross-section.

[0067] When the machine body is in an upright or tilted state, the gas-liquid mixture (dirt) enters the transfer channel 40 from the sewage inlet pipe 22, and finally enters the second chamber 212 along the axial direction of the barrel body 20 and away from the barrel cover 10, that is, Figure 6 As shown, the second outlet end of the transfer channel 40 is formed between the front wall 312 and the rear wall 321 and is opened toward the solid-liquid separation plate 33. The cross-sectional area of ​​the outlet end is the second outlet cross-sectional area. Figure 7As shown, when the fuselage is in a lying flat or nearly lying flat working state, the second chamber 212 of the sewage bucket is located directly above the first chamber 211. In this state, the outlet end of the transfer channel 40 is switched to the first outlet end having a larger cross-sectional area perpendicular to the dirty flow path than the second outlet end, i.e., the lying flat vent 3123. The cross-sectional area of ​​the lying flat vent 3123 is the above-mentioned first opening cross-sectional area, thereby adjusting the cross-sectional area of ​​the outlet end of the transfer channel 40 according to the different vertical distances from the air outlet 34 under different fuselage states, thereby ensuring that under different fuselage states, it is difficult for water vapor to reach the fan assembly through the air outlet 34, causing damage to it.

[0068] Specifically, in one embodiment of the present disclosure, the ratio between the area of ​​the lying-flat vent 3123 and the cross-sectional area of ​​the second channel 42 is greater than 3:1. Testing has shown that a ratio of greater than 3:1 between the area of ​​the lying-flat vent 3123 and the cross-sectional area of ​​the second channel 42 ensures smooth airflow along the second channel 42, thereby effectively improving the suction efficiency of the cleaning device of the present disclosure. Furthermore, when the cleaning device is in the lying-flat position, moisture carried in the airflow is retained below the second chamber 212 to the greatest extent possible under the action of its own gravity, rather than being carried into the fan unit by the airflow.

[0069] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, a rotation shaft 333 is provided on the solid-liquid separation plate 33. The rotation shaft 333 is configured to be located below the ventilation notch 3122. The second half-partition 32 is rotatably disposed between the first connecting portion 3111 and the second connecting portion 3112 via the rotation shaft 333. Because the rotation shaft 333 is located on the solid-liquid separation plate 33 and below the ventilation notch 3122, the second half-partition 32 can effectively open the second channel 42 when it rotates to the second position, making it easier for the user to clean dirt remaining in the second channel 42.

[0070] like Figure 1 As shown, in one embodiment of the present disclosure, the sewage inlet pipe 22 is constructed to extend along the axial direction of the sewage bucket to dock with the bottom inlet 3222 of the sewage pipe 322 located at one end of the first chamber 211 when the sewage pipe 322 is in the first position; the solid-liquid separation plate 33 includes a first separation portion 331 located in the first chamber 211 and a second separation portion 332 located in the second chamber 212, and the first separation portion 331 is provided with a notch for cooperating with the sewage inlet pipe 22.

[0071] Because the sewage inlet pipe 22 extends axially along the sewage bucket to connect with the bottom inlet 3222 of the sewage inlet pipe 322 at one end of the first chamber 211 when the sewage pipe 322 is in the first position, the sewage can flow rapidly along the sewage inlet pipe 22 under the negative pressure generated by the airflow, effectively improving the sewage suction efficiency of the cleaning device of the present disclosure and ensuring that all dirt on the work surface is sucked into the sewage bucket. Furthermore, because the first separation portion 331 of the solid-liquid separation plate 33 is provided with a notch for mating with the sewage inlet pipe 22, the solid-liquid separation portion can be ensured to not interfere with the normal layout of the sewage inlet pipe 22.

[0072] like Figure 2 and Figure 5 As shown, in one embodiment of the present disclosure, the cleaning device of the present disclosure also includes a water full detection probe 50, which includes a first detection end 51 and a second detection end 52. The first detection end 51 is arranged on the first connection part 3111, and the second detection end 52 is arranged on the second connection part 3112. The water full detection probe 50 is configured to trigger a water full signal when the first detection end 51 and the second detection end 52 are simultaneously immersed in water.

[0073] Specifically, no matter whether the cleaning device of the present invention is in a normal state, in a tilted or lying state, as long as the water level of the sewage in the sewage bucket reaches a certain height and simultaneously immerses the first detection end 51 and the second detection end 52, the water full detection probe 50 can trigger a water full signal, guiding the user to drain the sewage bucket, preventing excessive sewage in the sewage bucket, and avoiding malfunction of the fan unit due to water ingress, thereby effectively extending the service life of the cleaning device of the present invention and improving the user experience.

[0074] like Figure 1 and Figure 3 As shown, in one embodiment of the present disclosure, a first locking portion 3223 is provided on the top of the sewage pipe 322, and a second locking portion 12 is provided on the top surface of the barrel cover 10. The second half partition 32 is configured so that the first locking portion 3223 is engaged with the second locking portion 12 when in the first position, and rotates under the action of an external force to disengage the first locking portion 3223 from the second locking portion 12. At the same time, a torsion spring (not shown) is also provided on the rotating shaft 333. The force provided by the torsion spring causes the second half partition 32 to rotate open relative to the first half partition 31 when not locked in place, thereby reminding the user that the lock is in place and preventing the transfer channel 40 from not being enclosed and forming, resulting in reduced functionality.

[0075] Thus, when the cleaning device of the present disclosure is in operation, the first locking portion 3223 is engaged with the second locking portion 12, so that the second half partition 32 is in the first position and can form a transfer channel 40 with the first half partition 31, allowing sewage to flow normally along the transfer channel 40. When the user needs to clean the interior of the sewage bucket, the bucket cover 10 can be removed from the bucket body 20 and the second half partition 32 can be rotated to disengage the first locking portion 3223 from the second locking portion 12, thereby rotating the second half partition 32 to the second position, thereby opening the transfer channel 40 and facilitating the user to clean the dirt inside the transfer channel 40.

[0076] like Figures 1 to 8 As shown, the present disclosure also provides a sewage bucket, comprising:

[0077] The barrel body 20 has an inner cavity 21 and a sewage inlet pipe 22;

[0078] The barrel cover 10 is configured to be removably fastened to the barrel body 20. The barrel cover 10 is provided with a partition assembly 30 extending into the inner cavity 21. The inner cavity 21 has a first chamber 211 and a second chamber 212 arranged front and rear along the barrel body 20 by the partition assembly 30. The sewage inlet pipe 22 is located in the first chamber 211, and the barrel cover 10 is provided with an air outlet 34 located in the second chamber 212.

[0079] A transfer channel 40 is provided in the partition assembly 30 . The inlet end of the transfer channel 40 is communicated with the outlet of the sewage inlet pipe 22 , and the outlet end of the transfer channel 40 is provided in the second chamber 212 .

[0080] A transfer channel 40 is provided in the partition assembly 30, and the transfer channel 40 also includes an inlet end connected to the outlet of the sewage inlet pipe 22 located in the first chamber and an outlet end arranged in the second chamber 212, and the outlet end has a first outlet cross-section when the fuselage is in a lying-flat working mode and a second outlet cross-section when the fuselage is in a non-lying-flat working mode, wherein the first outlet cross-section is arranged horizontally and is defined by the partition assembly 30 and the solid-liquid separation plate 33, and the second outlet cross-section is also arranged horizontally and is defined by the partition assembly 30, and the area of ​​the first outlet cross-section is greater than the area of ​​the second outlet cross-section.

[0081] When the machine body is in an upright or tilted state, the gas-liquid mixture (dirt) enters the transfer channel 40 from the sewage inlet pipe 22, and finally enters the second chamber 212 along the axial direction of the barrel body 20 and away from the barrel cover 10, that is, Figure 6 As shown, the second outlet end of the transfer channel 40 is formed between the front wall 312 and the rear wall 321 and is opened toward the solid-liquid separation plate 33. The cross-sectional area of ​​the outlet end is the second outlet cross-sectional area. Figure 7As shown, when the fuselage is in a lying flat or nearly lying flat working state, the second chamber 212 of the sewage bucket is located directly above the first chamber 211. In this state, the outlet end of the transfer channel 40 is switched to the first outlet end having a larger cross-sectional area perpendicular to the dirty flow path than the second outlet end, i.e., the lying flat vent 3123. The cross-sectional area of ​​the lying flat vent 3123 is the above-mentioned first opening cross-sectional area, thereby adjusting the cross-sectional area of ​​the outlet end of the transfer channel 40 according to the different vertical distances from the air outlet 34 under different fuselage states, thereby ensuring that under different fuselage states, it is difficult for water vapor to reach the fan assembly through the air outlet 34, causing damage to it.

[0082] Application Scenario

[0083] The present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. The cleaning device includes a body and a sewage bucket provided on the body for accommodating sewage sucked from the work surface during the cleaning process. The sewage bucket includes a barrel body 20 and a barrel cover 10. The barrel body 20 has an inner cavity 21 and a sewage inlet pipe 22. The barrel cover 10 is constructed to be snapped onto the barrel body 20 in a detachable manner. The barrel cover 10 is provided with a partition assembly 30 extending into the inner cavity 21. Both sides of the partition assembly 30 abut against the inner wall surface of the inner cavity 21, so that the part of the inner cavity 21 corresponding to the partition assembly 30 is divided by the partition assembly 30 into a first chamber 211 and a second chamber 212 that are isolated from each other in the front and back. A transfer channel 40 is provided in the partition assembly 30. The end of the transfer channel 40 away from the barrel cover 10 is constructed to extend axially along the barrel body 20, and the end of the transfer channel 40 adjacent to the barrel cover 10 is constructed to extend into the first chamber 211 and communicate with the sewage inlet pipe 22 located in the first chamber 211; an air outlet 34 is provided at the bottom of the barrel cover 10, and the air outlet 34 is constructed to be located in the second chamber 212; in the cleaning equipment, the side where the air outlet 34 is located is the front side, and the side where the sewage inlet pipe 22 is located is the rear side, and the air outlet 34 is opened forward.

[0084] When in the upright and tilted states, the outlet of the transfer channel 40 extends roughly along the axial direction of the sewage bucket away from the bucket cover 10. When in the flat use state, the outlet direction of the transfer channel 40 is toward the front side, thereby achieving the adjustment of the cross-sectional area of ​​the outlet of the transfer channel 40 in different fuselage states under different use states.

[0085] It can be understood that the cleaning equipment disclosed herein also includes a fan unit, which is connected to the air outlet 34 through the filter installation port 11 on the barrel cover 10, and can form negative pressure in the inner cavity 21 of the sewage barrel through airflow; a sewage suction pipe is provided at the bottom of the fuselage, and the bottom opening of the sewage inlet pipe 22 of the sewage barrel is connected to the sewage suction pipe.

[0086] Therefore, during the operation of the cleaning device disclosed herein, the dirt on the working surface can enter the inlet end of the transfer channel 40 from the outlet of the sewage inlet pipe 22 located in the first chamber 211 along the sewage inlet pipe 22 under the action of the negative pressure generated by the fan unit, and then move along the transfer channel 40 and finally fall into the second chamber 212, and the air flow will flow from the air outlet 34 arranged above the second chamber 212 near the barrel cover 10 to the fan unit.

[0087] When the cleaning device of the present invention is in a normal state, the sewage is mainly located below the inner cavity 21 of the sewage bucket, away from the air outlet 34 above, and the sewage is not easy to enter the fan unit; when the cleaning device of the present invention is in a tilted or lying state, the body of the cleaning device will tilt toward the rear side, so that the first chamber 211 will be located obliquely below or directly below the second chamber 212. After the sewage falls into the second chamber 212, it will flow into the first chamber 211, and thus be located below the entire sewage bucket. The partition component 30 can suppress the splashes generated during the movement of the cleaning device, and by separating the air outlet 34 located in the second chamber 212 and the sewage stored in the first chamber 211, it is prevented that the sewage located in the first chamber 211 in the lying state directly passes over the partition component 30 and enters the second chamber 212. It is difficult for the sewage to enter the second chamber 212, thereby preventing the sewage from flowing along the air outlet 34 at the top of the second chamber 212 to the fan unit, thereby avoiding the fan unit from malfunctioning due to water ingress, effectively extending the service life of the cleaning device of the present invention, and thereby improving the user experience.

[0088] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terms used herein are selected to best explain the principles of the embodiments, their practical applications, or technical improvements in the marketplace, or to enable other persons skilled in the art to understand the embodiments disclosed herein.
