Description

Technical Field

[0001] The present disclosure relates to a structure for containing a cleaning liquid of a self - moving cleaning device, and more particularly to a cleaning liquid containing assembly and a self - moving cleaning device including the cleaning liquid containing assembly. Background Art

[0002] An autonomous mobile device refers to an intelligent mobile device that autonomously performs a preset task, and the autonomous mobile device can autonomously move on a traveling surface according to the result sensed by its sensing component. Currently, autonomous mobile devices generally include, but are not limited to, self - moving cleaning devices (such as intelligent sweepers, intelligent floor scrubbers, window - cleaning robots), companion - type mobile robots (such as intelligent electronic pets, nanny robots), service - type mobile robots (such as reception robots in hotels, inns, meeting places), industrial inspection intelligent devices (such as power inspection robots, intelligent forklifts, etc.), and security robots (such as household or commercial intelligent guard robots).

[0003] In a self - moving cleaning device having a wet cleaning component, the self - moving cleaning device includes a cleaning liquid containing assembly such as a water tank, and the cleaning liquid containing assembly generally contains a cleaning liquid such as water. When the cleaning liquid in the cleaning liquid containing assembly is consumed too much and needs to be replenished, the self - moving cleaning component will dock at a base station such as a charging stand or a charging pile, and the cleaning liquid containing assembly of the self - moving cleaning device will be replenished with the cleaning liquid through the liquid supply system in the base station. For this reason, in existing self - moving cleaning devices, the cleaning liquid containing assembly is formed with an exhaust structure that communicates its inside and outside, and the exhaust structure includes one or more holes. In this way, when replenishing the cleaning liquid into the cleaning liquid containing assembly, the air in the cleaning liquid containing assembly will be discharged through the exhaust structure. However, for the existing exhaust structure, the cleaning liquid is also likely to be discharged through the exhaust structure, so that the discharged cleaning liquid has an adverse effect on other components of the self - moving cleaning device. Summary of the Utility Model

[0004] Based on the problems of the above - mentioned prior art, the purpose of the present disclosure is to provide a cleaning liquid containing assembly that can smoothly discharge the internal air through the exhaust structure when replenishing the cleaning liquid in the containing assembly, and can also greatly reduce the risk of the cleaning liquid being discharged through the exhaust structure. Another purpose of the present disclosure is to provide a self - moving cleaning device including the above - mentioned cleaning liquid containing assembly.

[0005] To achieve the above purposes, the present disclosure adopts the following technical solutions.

[0006] The present disclosure provides a cleaning liquid containing assembly for a self - moving cleaning device. The cleaning liquid containing assembly includes a housing. An accommodation space for containing cleaning liquid is formed inside the housing. The housing includes a top wall and a bottom wall that define the accommodation space in the height direction of the cleaning liquid containing assembly. The top wall is formed with a protrusion that protrudes in a direction away from the bottom wall.

[0007] The housing has a column that stands up from the bottom wall towards the top wall. The column extends into the protrusion and is spaced apart from the top wall. An exhaust passage that communicates the accommodation space with the outside is formed inside the column. The exhaust passage has a first opening formed at the top end of the column facing the top wall.

[0008] In an alternative solution, a one - way valve is further included. The one - way valve is installed on the column such that air in the accommodation space is discharged unidirectionally towards the outside through the exhaust passage.

[0009] In another alternative solution, the one - way valve includes:

[0010] A valve body that is formed in a cylindrical shape. A valve cavity that communicates with the accommodation space is formed inside the valve body.

[0011] A flange portion that is fixedly connected to the valve body and protrudes towards the radial outside of the valve body. The flange portion is installed at the top end of the column; and

[0012] An elastic valve flap that is installed on the valve body. The two elastic valve flaps abut against each other in a natural state and can be separated from each other under the action of air pressure from the accommodation space. Thus, the two elastic valve flaps enable the valve cavity to be controllably communicated with the exhaust passage.

[0013] In another alternative solution, a stepped structure is formed at the top end of the column. The flange portion overlaps the stepped structure and abuts against the inner side surface of the stepped structure, and the top surface of the one - way valve is flush with the top surface of the column.

[0014] In another alternative solution, the one - way valve further includes a stop net. The stop net is installed on the valve body and is located at the opening of the valve cavity facing the top wall. The stop net matches the shape of the valve cavity and is formed into a porous structure that can stop the cleaning liquid and allow the air to pass through.

[0015] In another alternative solution, the housing further has a limiting seat located inside the protruding portion and fixed to the top wall. The top end portion of the upright column is inserted into the limiting seat and is in shape fit with the limiting seat. The flange portion is limited by the limiting seat and the upright column in the height direction. The limiting seat further forms a through hole communicating with the first opening.

[0016] In another alternative solution, a bent passage for the air to flow through is formed between the protruding portion and the limiting seat, so that the air can flow to the first opening via the bent passage and the through hole.

[0017] In another alternative solution, it further includes a wet cleaning assembly. The wet cleaning assembly includes a bracket and a wet cleaning member installed on the bracket. The bracket is installed on the housing and is located below the housing. The exhaust passage forms a second opening at the bottom end portion of the upright column, and the second opening faces the wet cleaning assembly.

[0018] In another alternative solution, the exhaust passage is configured to extend linearly along the height direction.

[0019] The present disclosure also provides a self - moving cleaning device, including the cleaning liquid containing assembly according to any one of the above - mentioned technical solutions.

[0020] By adopting the above - mentioned technical solutions, the present disclosure provides a cleaning liquid containing assembly and a self - moving cleaning device. The cleaning liquid containing assembly includes a housing, and an accommodation space for containing cleaning liquid is formed inside the housing. The housing includes a top wall and a bottom wall that define the accommodation space in the height direction of the cleaning liquid containing assembly. The top wall forms a protruding portion that protrudes in a direction away from the bottom wall. In addition, the housing has an upright column that stands up from the bottom wall and extends into the protruding portion and is spaced apart from the top wall. An exhaust passage for communicating the accommodation space with the outside is formed inside the upright column, and the exhaust passage forms an opening at the top end portion facing the top wall.

[0021] By adopting the above - mentioned solution, since the upper opening for the air to enter the exhaust passage is close to the top wall of the accommodation space, the risk that the upper opening of the exhaust passage is blocked by the cleaning liquid is greatly reduced, and thus the air in the accommodation space can be discharged smoothly and unobstructedly. Moreover, when the self - moving cleaning device including this cleaning liquid containing assembly is in a normal working state, the upper opening of the exhaust passage is always above the liquid level of the cleaning liquid such as water in the accommodation space, and it is difficult for the cleaning liquid to flow out from the exhaust passage, basically avoiding the adverse effects caused by the cleaning liquid flowing out from the exhaust passage to other components of the self - moving cleaning device.

[0034] Embodiments of the present disclosure will be described below with reference to the accompanying drawings. For ease of understanding, the elements shown in the respective drawings may include elements represented differently from the actual dimensions and scales, such as dimensions and scales.

[0035] In the present disclosure, unless otherwise specified, the height direction refers to the height direction of the cleaning liquid containing assembly.

[0036] The cleaning liquid containing assembly according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings of the specification.

[0037] The cleaning liquid containing assembly according to the present disclosure is configured to be part of the main body of a self - moving cleaning device, and the cleaning liquid containing assembly is assembled with other parts of the main body in a detachable manner. In this embodiment, as Figures 1 to 3 shown, the cleaning liquid containing assembly according to an embodiment of the present disclosure includes a housing 1, a one - way valve 2, and a wet cleaning assembly 3 assembled together.

[0038] It is sufficient to accommodate a sufficient amount of cleaning liquid in this space 1c. The housing 1 includes a top wall 11 and a bottom wall 12 that define an accommodation space 1c in the height direction D of the cleaning liquid containing assembly. The top wall 11 is located at the top of the accommodation space 1c, and the bottom wall 12 is located at the bottom of the accommodation space 1c. The top wall 11 is formed with a protrusion 111. The protrusion 111 protrudes in a direction away from the bottom wall 12 relative to the surrounding portion, whereby a hollow structure that opens towards the bottom wall 12 is surrounded by the protrusion 111. Further, the housing 1 has a column 121 that stands up from the bottom wall 12 towards the top wall 11. The column 121 extends linearly along the height direction D and is formed in a cylindrical structure. The column 121 extends into the hollow structure of the protrusion 111 and is spaced apart from the top wall 11. An exhaust passage 121p that communicates the accommodation space 1c with the outside is formed in the column 121. The exhaust passage 121p is configured to extend linearly along the height direction D to penetrate the entire column 121. The exhaust passage 121p forms a first opening 121o1 that opens towards the inside of the accommodation space 1c at the top end portion of the column 121 facing the top wall 11, and the exhaust passage 121p forms a second opening 121o2 that opens towards the outside of the accommodation space 1c at the bottom end portion of the column 121. By forming the above - mentioned exhaust passage 121p in the column 121, it is beneficial for the air in the accommodation space 1c to be discharged via the exhaust passage 121p. Further, as Figure 3 and Figure 4 shown, a stepped structure 121s is formed at the top end portion of the column 121, and the stepped structure 121s is used for installing the one - way valve 2, so that the exhaust passage 121p exhausts unidirectionally.

[0039] As Figure 3 and Figure 4As shown, the housing 1 further has a limiting seat 112. The limiting seat 112 is located within the hollow structure formed by the protrusion 111 and is fixed to the top wall 11. The limiting seat 112 can be fixedly connected to the side wall of the protrusion 111 through a plurality of spaced connection parts. The top end of the upright column 121 is inserted into the limiting seat 112 and is in shape fit with the limiting seat 112. The limiting seat 112 is also formed with a through hole communicating with the first opening 121o1 of the exhaust passage 121p. In this way, in the state where the top end of the upright column 121 is inserted into the limiting seat 112, it is possible to prevent the upright column 121 from tilting after the cleaning liquid containing assembly is installed in place. Moreover, since the limiting seat 112 is formed with a through hole communicating with the first opening 121o1 of the exhaust passage 121p, it does not prevent the air in the accommodation space 1c from being discharged through the exhaust passage 121p. In addition, a bent passage 11p for air circulation is formed between the protrusion 111 and the limiting seat 112, so that air can flow to the first opening 121o1 through the bent passage 11p and the through hole. In this way, even when the limiting seat 112 is provided, it is still possible to ensure that the air is discharged smoothly through the exhaust passage 121p, and the bent passage 11p forms a labyrinth structure for the cleaning liquid, thereby further reducing the probability of the cleaning liquid flowing out from the exhaust passage 121p.

[0040] In this embodiment, as Figure 3 and Figure 4 shown, the one-way valve 2 is a so-called duckbill valve and is installed at the top end of the upright column 121. The one-way valve 2 allows the air in the accommodation space 1c to be discharged unidirectionally toward the outside through the exhaust passage 121p. Specifically, the one-way valve 2 includes a valve body 21, a flange portion 22, an elastic valve flap 23, and a stop net 24 assembled together.

[0041] As Figure 3 and Figure 4As shown, the valve body 21 is formed in a cylindrical shape. A valve cavity 21c that is always in communication with the accommodation space 1c is formed inside the valve body 21. The valve cavity 21c extends along the height direction D and penetrates the entire valve body 21. The flange portion 22 extends continuously along the entire circumference of the valve body 21 and is fixedly connected to the valve body 21. The flange portion 22 protrudes toward the radially outer side of the valve body 21. The flange portion 22 overlaps the stepped structure 121s formed at the top end portion of the column 121, and the flange portion 22 can be in interference fit with the column 121 to abut against the inner side surface of the stepped structure 121s. The flange portion 22 is also clamped and limited by the limit seat 112 and the column 121 in the height direction D. Thus, the flange portion 22 is firmly installed at the top end portion of the column 121 and is stably supported by the column 121. Two elastic valve flaps 23 are installed on the valve body 21 and form a duckbill structure. The two elastic valve flaps 23 abut against each other in the natural state, so that the valve cavity 21c is disconnected from the exhaust passage 121p. After the air pressure in the accommodation space 1c increases due to the replenishment of the cleaning liquid into the accommodation space 1c, under the action of the air pressure from the accommodation space 1c, the two elastic valve flaps 23 can be separated from each other, so that the valve cavity 21c is in communication with the exhaust passage 121p. As the air in the accommodation space 1c is discharged to the outside of the accommodation space 1c through the exhaust passage 121p, and the air pressure in the accommodation space 1c decreases, the two elastic valve flaps 23 rely on their own elasticity to return to the state of abutting against each other. Thus, the valve cavity 21c is disconnected from the exhaust passage 121p. In this way, by controlling the state of the elastic valve flap 23 of the one-way valve 2 using the air pressure in the accommodation space 1c, the valve cavity 21c can be controlled to be in communication with the exhaust passage 121p.

[0042] In this way, the one-way valve 2 enables the exhaust passage 121p to have a one-way exhaust function. Thus, only the air in the accommodation space 1c is allowed to be discharged toward the outside of the accommodation space 1c through the exhaust passage 121p, and the outside air cannot enter the accommodation space 1c in the reverse direction. Moreover, the one-way valve 2 is formed into a so-called duckbill valve, and the one-way valve 2 has a relatively simple and reliable structure. Further, the top surface of the one-way valve 2 is configured to be flush with the top surface of the column 121. On the one hand, the one-way valve 2 does not protrude from the column 121, so it does not occupy extra space. On the other hand, even if the cleaning liquid in the accommodation space 1c flows to the top of the column 121 with a low probability, it will be blocked by the one-way valve 2, so that there will not be too much cleaning liquid accumulating at the position of the first opening 121o1 (upper opening) of the exhaust passage 121p.

[0043] As Figure 3 and Figure 4As shown, the stop net 24 is located at the opening of the valve chamber 21c facing the top wall 11, and the stop net 24 matches the shape of the valve chamber 21c. The stop net 24 can have a large number of fine mesh holes, whereby the stop net 24 is formed into a porous structure capable of stopping the cleaning liquid but allowing air to pass through. By providing the stop net 24, it can be further ensured that the cleaning liquid does not enter the exhaust passage 121p via the one-way valve 2, but air can smoothly enter the exhaust passage 121p via the one-way valve 2 and be discharged.

[0044] In this embodiment, as Figure 3 and Figure 4 shown, the wet cleaning assembly 3 includes a bracket 31 and a wet cleaning member 32 mounted on the bracket 31. The bracket 31 can be formed into different structures as needed, and the bracket 31 is detachably mounted on the housing 1 and is located below the housing 1. A wet cleaning member 32 such as a rag or a mop is mounted on the bracket 31 and is located below the bracket 31. After the cleaning liquid containing assembly is assembled, the second opening 121o2 of the exhaust passage 121p of the column 121 faces the wet cleaning assembly 3. Therefore, even if a very small amount of cleaning liquid is discharged through the exhaust passage 121p, it will be absorbed by the wet cleaning member 32 such as a rag or a mop of the wet cleaning assembly 3, and thus will not fall onto the surface to be cleaned where the self-moving cleaning device moves autonomously.

[0045] By adopting the above solution, since the first opening 121o1 (upper opening) of the exhaust passage 121p is close to the top wall 11 of the accommodation space 1c, the risk that the upper opening of the exhaust passage 121p is blocked by the cleaning liquid is greatly reduced, whereby the air in the accommodation space 1c can be discharged smoothly and unobstructedly. Moreover, when the self-moving cleaning device including this cleaning liquid containing assembly is in a normal working state, the upper opening of the exhaust passage 121p is always above the liquid level of the cleaning liquid such as water in the accommodation space 1c, and it is difficult for the cleaning liquid to flow out from the exhaust passage 121p, basically avoiding the adverse effects caused by the cleaning liquid flowing out from the exhaust passage 121p on other components of the self-moving cleaning device. Moreover, by providing the one-way valve 2 including the stop net 24, even when the cleaning liquid containing assembly is inverted, it can be basically avoided that the cleaning liquid flows out from the exhaust passage 121p.

[0046] Furthermore, in this embodiment, as Figure 1 、 Figure 5 and Figure 6 shown, the housing 1 of the cleaning liquid containing assembly is formed with a liquid inlet passage 1p, and the liquid inlet passage 1p has an opening that is open on the side wall of the cleaning liquid containing assembly. The liquid inlet passage 1p is also communicated with the accommodation space 1c of the cleaning liquid containing assembly. When the self-moving cleaning device including the cleaning liquid containing assembly according to the present disclosure is docked at a base station such as a charging dock or a charging pile, asFigure 6 As shown, the liquid injection nozzle of the liquid injection assembly of the base station can be inserted into the liquid inlet passage 1p and supplement the cleaning liquid into the accommodation space 1c via the liquid inlet passage 1p.

[0047] The self - moving cleaning device according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings of the specification.

[0048] As Figure 7 shown, the self - moving cleaning device according to an embodiment of the present disclosure includes the cleaning liquid accommodation assembly described above, and the cleaning liquid accommodation assembly can form a part of the main body of the self - moving cleaning device. In a top view, the overall shape of the main body of the self - moving cleaning device can be circular, and in other alternative solutions, it can be formed into various other shapes such as D - shaped, oval, square, etc. When the self - moving cleaning device is in a normal operating state, the bottom surface of the main body faces the surface to be cleaned, and the bottom surface of the main body is usually parallel to the surface to be cleaned. Here, "parallel" not only includes the geometric parallel relationship between the bottom surface of the main body and the surface to be cleaned, but also includes the case where the two are approximately parallel. The above "approximately" means that within the reasonable error range recognized by those skilled in the art, the parallel relationship between the two can be determined to be established. For example, when the acute - angle between the bottom surface of the main body and the surface to be cleaned is not greater than 5 degrees, the two can be considered to be parallel to each other. In addition, in order to support and protect other components, other components of the self - moving cleaning device are usually installed inside the main body or have a connection relationship with the main body.

[0049] The self - moving cleaning device can move autonomously according to the preset control scheme in its processing unit. The surface to be cleaned where the self - moving cleaning device moves autonomously can be a flat surface or a curved surface with a relatively large radius of curvature. Typically, for example, it is the floor in each room of a building. The processing unit in this disclosure is a general term, and there are no restrictions on the type, quantity, and form of the processing unit. Specifically, the processing unit can be one or several of MCU, DSP, FPGA, GPU, or other various hardware chips, processors, or software algorithms with data processing and computing capabilities. Further, the processing unit can be the unified and unique processor of the self - moving cleaning device, or a collection of multiple processing units. The connection method, functions, and computing power distribution of multiple processing units can be adjusted as needed. For example, in an alternative solution, it can include a first processing unit and a second processing unit. In this case, the first processing unit and the second processing unit together implement various functions of the above - mentioned processing unit. In addition, the processing unit of the self - moving cleaning device according to this disclosure can receive parameters from the sensing component and can control the self - moving cleaning device through the preset program stored in the storage unit. In this disclosure, the data, information, and programs required by the processing unit during the processing can be stored in the storage unit and obtained from the storage unit as needed. The processing unit can store the processed data, information, etc. in the storage unit again. The storage unit can be RAM, ROM, etc., or devices and / or equipment with storage functions such as cloud / servers / mobile terminals connected through wired / wireless networks.

[0050] In addition to including the above - mentioned wet cleaning component 3, the self - moving cleaning device can also include a dry cleaning component. The dry cleaning component is arranged in other parts of the main body and can include a main brush, side brushes (edge brushes), and a suction device, etc. Thus, when the self - moving cleaning device is moving on the surface to be cleaned, the surface to be cleaned can be cleaned through the dry cleaning component and / or the wet cleaning component 3. In different working modes, the cleaning operations achieved by the self - moving cleaning device include, but are not limited to, one or more of operations such as sweeping, mopping, and vacuuming.

[0051] It should be understood that the above - mentioned embodiments are merely exemplary and do not limit this disclosure. Those skilled in the art can make various variations and changes to the above - mentioned embodiments under the teaching of this disclosure without departing from the scope of this disclosure. The following supplementary explanations are made for the technical solutions of this disclosure.

[0052] i. In the above - mentioned specific embodiments, it is illustrated that the cleaning liquid containing component includes the wet cleaning component 3, but this disclosure is not limited thereto. In other alternative solutions, the wet cleaning component 3 can be independent of the cleaning liquid containing component.

[0053] ii. In the above specific embodiments, it is illustrated that the one-way valve 2 provided on the column 121 of the cleaning liquid containing assembly is a so-called duckbill valve, but the present disclosure is not limited thereto. In other alternative solutions, as long as the air in the accommodation space 1c can be discharged unidirectionally through the exhaust passage, a one-way valve 2 with any structure can be adopted as needed.

[0054] iii. In the above specific embodiments, it is illustrated that the limiting seat 112 is a part of the housing 1 and the stop net 24 is a part of the one-way valve 2, but the present disclosure is not limited thereto. The limiting seat and the stop net can be integrated together to form a single-piece structure (such as a cover) independent of the housing and the one-way valve. The stop net is arranged in the through hole of the limiting seat, and this single-piece structure can be fixedly installed at the top end of the column by an interference fit method.

[0055] iv. It can be understood that the cleaning liquid containing assembly described in the present disclosure is not only applicable to self-moving cleaning devices, but also can be applied to other application fields or application scenarios.
