Water outlet device and cleaning robot

Abstract

The utility model is suitable for the technical field of cleaning, and provides a water outlet device and a cleaning robot. The cleaning device comprises a water tank and a pipeline structure. A containing cavity is formed in the water tank, and an air inlet and a plurality of first water outlets are formed in the inner wall of the containing cavity at intervals. The pipeline structure is arranged in the containing cavity and provided with a water inlet and a plurality of second water outlets which are distributed at intervals, each second water outlet communicates with at least one first water outlet, and the water inlet communicates with the containing cavity. When the water outlet device is obliquely placed, under the condition that gas is not introduced into the containing cavity, the air pressure in the containing cavity is small, so that the air pressure in the containing cavity is difficult to drive water to flow into the pipeline structure. Thus, when the water outlet device is obliquely placed, water is not prone to entering the pipeline structure through the water inlet and then not prone to flowing out of the first water outlet through the second water outlet, and the problem that the cleaning robot is prone to water leakage under the condition that the cleaning robot is obliquely placed is solved.

Description

Technical Field

[0001] This application belongs to the field of cleaning. More specifically, it relates to a water outlet device and a cleaning robot. Background Art

[0002] In related technologies, cleaning robots usually wet mops through a water outlet device to perform cleaning activities such as mopping the floor. Specifically, the water outlet device includes a water tank and an air pump. The water tank has a receiving cavity, and two spaced-apart water outlets are provided at the bottom of the receiving cavity. The water outlets can direct water towards the mop. When in use, the air pump inflates the receiving cavity, increasing the gas pressure inside the receiving cavity. When the air pressure inside the receiving cavity is greater than or equal to the external atmospheric pressure, the water inside the receiving cavity can flow out from the water outlets under the action of gravity or air pressure to wet the mop.

[0003] However, when the cleaning robot is not in use, it may be placed with the body tilted, which may cause the water tank to tilt. As a result, one of the water outlets may not be covered by water, and air will enter the receiving cavity through this water outlet. At this time, the air pressure inside the receiving cavity is equal to the external atmospheric pressure, and the surface tension of the water cannot support the gravity of the water. Then the water inside the receiving cavity will flow out from the other water outlet, making the cleaning robot prone to water leakage when placed in a tilted state. Utility Model Content

[0004] One of the purposes of the embodiments of this application is to provide a water outlet device and a cleaning robot, aiming to solve the technical problem that the cleaning robot is prone to water leakage when placed in a tilted state in related technologies.

[0005] To solve the above technical problem, the technical solution adopted in the embodiments of this application is:

[0006] In the first aspect, a water outlet device is provided, including:

[0007] A water tank with a receiving cavity inside, and an air inlet and a plurality of first water outlets are spaced apart on the inner wall of the receiving cavity;

[0008] A pipeline structure disposed inside the receiving cavity; the pipeline structure is provided with a spaced-apart water inlet and a plurality of second water outlets, each of the second water outlets communicates with at least one of the first water outlets, and the water inlet communicates with the receiving cavity.

[0009] In some embodiments, the inner wall of the receiving cavity includes a first wall, and the first water outlets are disposed on the first wall; the water inlet is disposed at one end of the pipeline structure facing the first wall and is spaced apart from the first wall.

[0010] In some embodiments, the pipeline structure includes a connecting pipe and a plurality of branch pipes. The connecting pipe communicates with the plurality of branch pipes, and the second water outlet is provided on the branch pipes. The connecting pipe protrudes from the branch pipes toward the first wall and is spaced apart from the first wall. The water inlet is provided at one end of the connecting pipe facing the first wall.

[0011] In some embodiments, a groove is provided at a position on the first wall opposite to the water inlet. A part of the connecting pipe is disposed in the groove. The groove communicates with the accommodating cavity and the water inlet respectively, so that the accommodating cavity communicates with the water inlet.

[0012] In some embodiments, the connecting pipe is provided with an avoidance groove. A part of the avoidance groove is located in the groove to communicate with the groove and the accommodating cavity. The water inlet is provided on the groove wall of the avoidance groove, so that the water inlet communicates with the groove.

[0013] In some embodiments, the avoidance groove penetrates the connecting pipe, and the penetrating direction of the avoidance groove intersects the direction in which the connecting pipe is inserted into the groove.

[0014] In some embodiments, the groove wall of the groove includes a bottom wall and a side wall. The bottom wall and the air inlet are spaced apart and opposite to each other. The side wall is connected to the outer periphery of the bottom wall, and at least a part of the side wall is gradually expanded in the direction from the bottom wall to the water inlet.

[0015] In some embodiments, the inner wall of the accommodating cavity further includes a second wall. The second wall is spaced apart and opposite to the first wall, and the air inlet is provided on the second wall.

[0016] In some embodiments, the water tank is provided with a mounting portion. The mounting portion is disposed in the accommodating cavity and is provided with a through hole. The through hole communicates with the first water outlet. The pipeline structure is connected to the mounting portion so that the second water outlet communicates with the through hole.

[0017] In a second aspect, a cleaning robot is provided. The cleaning robot according to the embodiments of the second aspect of the present application includes a traveling mechanism and the water outlet device according to the embodiments of the first aspect of the present application. The water tank of the water outlet device is used to supply water to the mopping cloth through the first water outlet, and the traveling mechanism is used to drive the water outlet device to travel.

[0018] The beneficial effects of the water outlet device and the cleaning robot provided by the embodiments of the present application are as follows:

[0019] When the water outlet device provided by the embodiment of the present application is in use, air is inflated into the accommodating cavity through the air inlet. When the air pressure in the accommodating cavity is greater than or equal to the atmospheric pressure, the water in the water tank will flow towards the water inlet under the action of gravity or air pressure, and flow into the pipeline structure from the water inlet, and then flow through the pipeline structure and flow out from the second water outlet. Each second water outlet is communicated with at least one first water outlet, so that water can flow out from the first water outlet. When the water outlet device is placed obliquely, in the case where no gas is introduced into the accommodating cavity, the air pressure in the accommodating cavity is small, making it difficult for the air pressure in the accommodating cavity to drive water into the pipeline structure. In this way, when the water outlet device is placed obliquely, it is not easy for water to enter the pipeline structure through the water inlet, and thus it is not easy to flow out from the first water outlet through the second water outlet, improving the problem that the cleaning robot is prone to water leakage when placed obliquely.

[0035] The following will be described in detail in combination with specific drawings and embodiments:

[0036] An embodiment of the present application provides a water outlet device 100 for discharging water towards a specified area. For example, when the water outlet device 100 is applied to a cleaning robot, the water outlet device 100 can discharge water towards a rag to wet the rag, so that the cleaning robot can perform cleaning activities such as mopping the floor with the wet rag. In addition, the water outlet device 100 can also be applied to other devices such as a drip device and a circulating water machine.

[0037] Please refer to Figures 1 to 5 , the water outlet device 100 includes a water tank 10 and a pipe structure 20. The water tank 10 is provided with a receiving cavity 11. The inner wall of the receiving cavity 11 is provided with an air inlet 1121 and a plurality of first water outlets 1112. The air inlet 1121 and the plurality of first water outlets 1112 are arranged at intervals, and the plurality of first water outlets 1112 are also arranged at intervals with each other. The pipe structure 20 is arranged in the receiving cavity 11. The pipe structure 20 is provided with a water inlet 211 and a plurality of second water outlets 221. The water inlet 211 and the plurality of second water outlets 221 are distributed at intervals, and the plurality of second water outlets 221 are distributed at intervals between them. Each second water outlet 221 communicates with at least one first water outlet 1112. The water inlet 211 communicates with the receiving cavity 11.

[0038] The water tank 10 is used to store liquid. In a possible design, the water tank 10 includes an upper shell 13 and a lower shell 14. The upper shell 13 and the lower shell 14 can be connected by means of snap connection, bonding, bolt connection, etc., so that the upper shell 13 and the lower shell 14 enclose each other to form a receiving cavity 11 for storing liquid.

[0039] The air inlet 1121 and the first water outlet 1112 penetrate through the inner wall of the receiving cavity 11, so that the air outside the water tank 10 can enter the receiving cavity 11 through the air inlet 1121, and the water in the receiving cavity 11 can also flow out of the water tank 10 through the first water outlet 1112.

[0040] The air inlet 1121 is used for air intake. Specifically, the air inlet 1121 can inflate the receiving cavity 11 by connecting to air or connecting to an air pump, etc.

[0041] Wherein, a flow channel 23 is provided in the pipe structure 20. The flow channel 23 communicates with the water inlet 211 and the second water outlet 221. The water entering from the water inlet 211 can flow through the flow channel 23 and flow out from the second water outlet 221.

[0042] In one implementation, the second water outlet 221 can be simultaneously communicated with a plurality of first water outlets 1112; alternatively, in another implementation, one second water outlet 221 is communicated with the outer peripheral side of one first water outlet 1112, so that the first water outlet 1112 and the second water outlet 221 are in one-to-one correspondence and communication. The specific connection manner of the first water outlet 1112 and the second water outlet 221 can be selected according to actual needs and is not limited herein.

[0043] During actual use, gas is introduced at the air inlet 1121, and the introduced gas is above the water, so that the pressure above the water gradually increases until the gas pressure in the accommodation chamber 11 can offset the atmospheric pressure at the first water outlet 1112, and the water can flow out from the first water outlet 1112 under the action of gravity. In this way, the gravity of the water can promote the outflow of the water from the first water outlet 1112, reduce the inflation time into the accommodation chamber 11, and reduce the energy consumption of the water outlet device 100.

[0044] When the water outlet device 100 provided in the embodiment of the present application is in use, air is inflated into the accommodation chamber 11 through the air inlet 1121. When the air pressure in the accommodation chamber 11 is greater than or equal to the atmospheric pressure, the water in the water tank 10 will flow towards the water inlet 211 under the action of gravity or air pressure, and flow into the pipeline structure 20 from the water inlet 211, and then flow through the pipeline structure 20 and flow out from the second water outlet 221. Each second water outlet 221 is communicated with at least one first water outlet 1112, so that the water can flow out from the first water outlet 1112. When the water outlet device 100 is placed obliquely, in the case where no gas is introduced into the accommodation chamber 11, the air pressure in the accommodation chamber 11 is small, so that it is difficult for the air pressure in the accommodation chamber 11 to drive the water to flow into the pipeline structure 20. In this way, when the water outlet device 100 is placed obliquely, the water is not easily introduced into the pipeline structure 20 through the water inlet 211, and thus is not easily flowed out from the first water outlet 1112 through the second water outlet 221, improving the problem that the cleaning robot is prone to water leakage when placed obliquely.

[0045] In some embodiments, please refer to Figures 3 to 5 , the inner wall of the accommodation chamber 11 includes a first wall 111. The first water outlet 1112 is provided on the first wall 111. The water inlet 211 is provided at one end of the pipeline structure 20 close to the first wall 111. The water inlet 211 and the first wall 111 are arranged at intervals.

[0046] When the water tank 10 is located on a horizontal plane, the first wall 111 is at the bottom of the receiving cavity 11 in the vertical direction. During operation, gas is filled into the air inlet 1121, and the gas accumulates above in the receiving cavity 11, causing the water to flow downward under the action of the gas pressure and gravity. The water flows into the pipeline structure 20 from the water inlet 211, then flows through the pipeline structure 20 to the second water outlet 221, and finally flows out from the first water outlet 1112 on the first wall 111.

[0047] By arranging the water inlet 211 at one end close to the first wall 111, the water on the side of the receiving cavity 11 close to the first wall 111 can flow smoothly into the water inlet 211 as much as possible. In this way, when the water level in the receiving cavity 11 is relatively low, as much water as possible can also enter the water inlet 211 and then flow out from the first water outlet 1112.

[0048] In some embodiments, please refer to Figures 4 to 6 , the pipeline structure 20 includes a connecting pipe 21 and a plurality of branch pipes 22. The connecting pipe 21 communicates with the plurality of branch pipes 22. The second water outlet 221 is provided on the branch pipe 22. The connecting pipe 21 protrudes towards the first wall 111 beyond the branch pipes 22. The connecting pipe 21 and the first wall 111 are spaced apart. The water inlet 211 is provided at one end of the connecting pipe 21 facing the first wall 111.

[0049] There is a gap between the connecting pipe 21 and the first wall 111, so that the water in the receiving cavity 11 can enter the water inlet 211 from the gap between the connecting pipe 21 and the first wall 111. By the connecting pipe 21 protruding towards the first wall 111 beyond the branch pipes 22, the distance between the water inlet 211 and the first wall 111 is further reduced.

[0050] In this way, the water inlet 211 is arranged to be closer to the first wall 111, further reducing the distance between the water inlet 211 and the first wall 111. As much as possible, the water near the first wall 111 in the receiving cavity 11 can smoothly enter the water inlet 211. When the water level in the receiving cavity 11 is relatively low, the water can also smoothly enter the water inlet 211 and flow out from the first water outlet 1112, improving the use reliability of the water outlet device 100.

[0051] In some embodiments, please refer to Figure 5 and Figure 6 , a groove 1111 is provided on the first wall 111. The groove 1111 is arranged opposite to the water inlet 211. A part of the connecting pipe 21 is arranged in the groove 1111. The groove 1111 communicates with the receiving cavity 11 and the water inlet 211 respectively, so that the receiving cavity 11 communicates with the water inlet 211.

[0052] When the water tank 10 is on a horizontal plane, the first wall 111 is at the bottom of the accommodating cavity 11. A groove 1111 is provided on the first wall 111, and the horizontal height at each position in the groove 1111 is lower than the horizontal height at the non-groove 1111 part of the first wall 111. In this way, when the water is at a position on the first wall 111 other than the groove 1111, the water can flow from other positions on the first wall 111 into the groove 1111 under the action of gravity.

[0053] In this way, the water inside the accommodating cavity 11 can enter the groove 1111 and flow from the groove 1111 to the water inlet 211 under the action of air pressure or gravity, avoiding the problem that the connecting pipe 21 blocks the water. At the same time, by arranging part of the connecting pipe 21 in the groove 1111, the water can also flow into the groove 1111 when the water level in the accommodating cavity 11 is relatively low, and then enter the pipeline structure 20 through the water inlet 211. Then, the user does not need to frequently inject water into the accommodating cavity 11, improving the durability of the water outlet device 100.

[0054] In some embodiments, please refer to Figures 5 to 7 , the connecting pipe 21 is provided with an avoidance groove 212. The avoidance groove 212 is partially located in the groove 1111 to communicate with the groove 1111 and the accommodating cavity 11. The water inlet 211 is provided on the groove wall of the avoidance groove 212 to communicate the water inlet 211 with the groove 1111.

[0055] Specifically, a part of the avoidance groove 212 is located outside the groove 1111 and a part is located inside the groove 1111, so that the part of the avoidance groove 212 located outside the groove 1111 can allow the water in the accommodating cavity 11 to flow in, and the water flowing into the avoidance groove 212 can flow from the avoidance groove 212 into the groove 1111 to realize the mutual communication between the groove 1111 and the accommodating cavity 11.

[0056] The water inlet 211 is arranged on the groove wall of the avoidance groove 212. Specifically, the water inlet 211 can be arranged on the part of the groove wall of the avoidance groove 212 located inside the groove 1111; or, the water inlet 211 can also be arranged on the part of the groove wall of the avoidance groove 212 located outside the groove 1111.

[0057] By providing the avoidance groove 212, the conduction area between the groove 1111 and the accommodating cavity 11 is further increased, so that the water in the accommodating cavity 11 can more easily enter the groove 1111 through the avoidance groove 212, and then enter the water inlet 211 from the groove 1111, improving the water inlet efficiency of the water in the accommodating cavity 11 towards the water inlet 211.

[0058] In one embodiment, the outer diameter of the connecting pipe 21 is smaller than the inner diameter of the groove 1111, so that a gap is formed between the connecting pipe 21 and the groove 1111. The water in the accommodating cavity 11 can flow into the groove 1111 through the above gap under the action of air pressure or gravity, so as to enter the water inlet 211 through the groove 1111. Wherein, the water inlet 211 can be located in the groove 1111, or the water inlet 211 can also be located outside the groove 1111.

[0059] In one embodiment, the avoidance groove 212 can also be located outside the groove 1111. At this time, the water in the accommodating cavity 11 can flow into the groove 1111 through the avoidance groove 212 under the action of air pressure or gravity, so as to flow into the water inlet 211 from the groove 1111. Wherein, the avoidance groove 212 is arranged outside the groove 1111, and the water inlet 211 can be arranged on the groove wall of the avoidance groove 212, so that the water inlet 211 is also located outside the groove 1111.

[0060] In some embodiments, please refer to Figure 6 , the avoidance groove 212 is arranged through the connecting pipe 21. The through direction of the avoidance groove 212 intersects with the direction in which the connecting pipe 21 is inserted into the groove 1111.

[0061] In a possible design, openings are provided at opposite ends of the avoidance groove 212 along the through direction, and both openings communicate with the accommodating cavity 11. The water in the accommodating cavity 11 can enter the avoidance groove 212 through the openings of the avoidance groove 212.

[0062] In this way, the water in the accommodating cavity 11 can directly enter the groove 1111 through the avoidance groove 212 as much as possible, improving the water inlet efficiency of the water in the accommodating cavity 11 towards the water inlet 211.

[0063] In some embodiments, please refer to Figure 6 , the groove wall of the groove 1111 includes a bottom wall 11111 and a side wall 11112. The bottom wall 11111 and the air inlet 1121 are spaced apart and oppositely arranged. The side wall 11112 is connected to the outer periphery of the bottom wall 11111. At least part of the side wall 11112 is tapered in the direction from the bottom wall 11111 towards the water inlet 211.

[0064] This setting makes the interval between at least part of the side wall 11112 of the groove 1111 and the connecting pipe 21 gradually increase, which is beneficial to the water in the accommodating cavity 11 to enter the groove 1111, and then facilitates the water to enter the pipeline structure 20, thereby improving the water outlet efficiency of the water outlet device 100.

[0065] In some embodiments, please refer to Figure 4 , the inner wall of the accommodating cavity 11 further includes a second wall 112. The second wall 112 is spaced apart and oppositely arranged relative to the first wall 111. The air inlet 1121 is arranged on the second wall 112.

[0066] As an example, the water tank 10 can be set to be horizontally placed. At this time, the first wall 111 and the second wall 112 are respectively two inner walls of the accommodating cavity 11 in the vertical direction. The second wall 112 is arranged above the first wall 111, and the air inlet 1121 is arranged on the second wall 112.

[0067] In this way, it is beneficial for gas to enter the accommodating cavity 11 better. When the water level in the accommodating cavity 11 is relatively high, water is not likely to flow out from the air inlet 1121, improving the use safety of the water outlet device 100. During actual use, the water outlet device 100 is set such that gas enters the accommodating cavity 11 from above and water flows out of the accommodating cavity 11 from below, improving the stability of the air intake and water outlet cycle of the water outlet device 100.

[0068] In some embodiments, please refer to Figure 4 , the water tank 10 is provided with a mounting portion 12. The mounting portion 12 is arranged in the accommodating cavity 11 and is provided with a through hole 121 therethrough. The through hole 121 communicates with the first water outlet 1112. The pipeline structure 20 is connected to the mounting portion 12 so that the second water outlet 221 communicates with the through hole 121.

[0069] The mounting portion 12 can be structures such as bumps or convex columns arranged in the accommodating cavity 11. Specifically, the pipeline structure 20 can be sleeved on the outer peripheral side of the mounting portion 12 so that the second water outlet 221 communicates with the through hole 121. Or, the mounting portion 12 can be sleeved on the outer peripheral side of the pipeline structure 20 so that the second water outlet 221 communicates with the through hole 121. The connection manner between the mounting portion 12 and the pipeline structure 20 is not limited to the above two, and can also be other forms.

[0070] In this way, the pipeline structure 20 can be more stably installed in the accommodating cavity 11 through the mounting portion 12, so that the pipeline structure 20 is not likely to shake in the installation cavity 210, and further the second water outlet 221 is not likely to be separated from the first water outlet 1112, improving the connection stability between the first water outlet 1112 and the second water outlet 221, and making the water outlet of the water outlet device 100 more stable and reliable.

[0071] Please refer to Figures 1 to 5 , the second aspect embodiment of the present application provides a cleaning robot. The cleaning robot includes a traveling mechanism and the water outlet device 100 of the first aspect embodiment of the present application. The water tank 10 of the water outlet device 100 is used for supplying water to the mopping cloth through the first water outlet 1112, and the traveling mechanism is used for driving the water outlet device 100 to travel.

[0072] Among them, the water outlet device 100 and the water tank 10 involved in the embodiments of the present application are the same as the water outlet device 100 and the water tank 10 involved in the above embodiments. Specifically, reference can be made to the relevant descriptions above, and details will not be repeated here.

[0073] In a possible design, the mop directly covers the first water outlet 1112, so that the water flowing out of the first water outlet 1112 can directly wet the mop. In another possible design, the water tank 10 is provided with structures such as a conduit communicating with the first water outlet 1112, and the water flowing out of the first water outlet 1112 can be guided to the mop through the conduit, thereby wetting the mop.

[0074] In a possible design, the traveling mechanism may include a control component, a driving component, wheels, etc. The driving component is used to drive the wheels to rotate to achieve the forward operation of the traveling mechanism. The control component can control the traveling path and obstacle avoidance route of the traveling mechanism, etc.

[0075] During use, air is inflated into the accommodating cavity 11 through the air inlet 1121. When the air pressure in the accommodating cavity 11 is greater than or equal to the atmospheric pressure, the water in the water tank 10 will flow towards the water inlet 211 under the action of gravity or air pressure, and flow into the pipeline structure 20 from the water inlet 211, and then flow through the pipeline structure 20 and flow out from the second water outlet 221, and then flow out from the first water outlet 1112. The water flowing out of the first water outlet 1112 can wet the mop, and the traveling mechanism can drive the water outlet device 100 to travel along a preset path to clean the ground on the preset path with the wet mop.

[0076] For the cleaning robot provided by the embodiment of the present application, when the water outlet device 100 is placed obliquely, in the case where no gas is introduced into the accommodating cavity 11, the air pressure in the accommodating cavity 11 is small, so that it is difficult for the air pressure in the accommodating cavity 11 to drive the water to flow into the pipeline structure 20. In this way, when the water outlet device 100 is placed obliquely, the water is not easy to enter the pipeline structure 20 through the water inlet 211, and thus is not easy to flow out from the first water outlet 1112 through the second water outlet 221, improving the problem that the cleaning robot is prone to water leakage when placed obliquely.

[0077] In one embodiment, as Figure 5 shown, the cleaning robot further includes a housing 200. The housing 200 and the water tank 10 can be stacked in sequence along the thickness direction. The housing 200 and the water tank 10 enclose an installation cavity 210 for accommodating components such as an air pump or components of the traveling mechanism. The installation cavity 210 is separated from the accommodating cavity 11 so that the water in the accommodating cavity 11 will not affect the operation of the components in the installation cavity 210, improving the use safety of the cleaning robot.

[0078] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
