Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of cleaning equipment, and in particular to a cleaning base station and cleaning equipment. Background Art

[0002] With the development of science and technology, automated floor cleaning robots have gradually entered family life. Among them, robots with mopping functions are mostly equipped with a clean water tank and a dirty water tank. The water in the clean water tank is used to soak wiping items such as rags, and the space in the dirty water tank is used to recycle the dirty water generated after mopping.

[0003] In the related art, most cleaning robots are equipped with a base station for charging, watering and draining. The base station has a water filling pipe for connecting to the clean water tank of the cleaning robot. When adding water, the water pump is started, and the water in the base station enters the clean water tank of the cleaning robot through the water filling pipe under the guidance of the water pump. When the clean water tank of the cleaning robot is full of water, the water pump is turned off, and the cleaning robot leaves the base station.

[0004] However, when the cleaning robot is separated from the base station, the vibration generated by the base station causes the water remaining in the water filling pipe to flow out. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a cleaning base station and a cleaning device, which can solve the problem that when the cleaning robot leaves the base station, the vibration generated by the base station will cause the water remaining in the water filling pipe to flow out.

[0006] To achieve the above-mentioned purpose, one aspect of an embodiment of the present application provides a cleaning base station, including a main body and a guide assembly, the main body having a water tank, and the guide assembly comprising: a tube group, having a first open end and a second open end, and the first open end is connected to the water tank; a valve core, movably arranged in the inner cavity of the tube group, and having a first position that closes the second open end of the tube group and a second position that connects the second open end of the tube group; a reset member, connected to the valve core, and the reset member is used to provide a reset force for the valve core to move from the second position to the first position.

[0007] To achieve the above-mentioned purpose, another aspect of an embodiment of the present application further provides a cleaning device, including a cleaning robot and the cleaning base station as described above. When adding water, the second open end of the guide assembly of the base station is connected to the clean water tank of the cleaning robot.

[0008] It can be seen that the cleaning base station and cleaning equipment provided by the embodiment of the present application connect the water storage tank of the cleaning base station with the clean water tank of the cleaning robot through the diversion component. Among them, the diversion device includes a pipe group, a valve core movably arranged in the inner cavity of the pipe group, and a reset member connected to the valve core. When adding water, the water pump can be turned on, and the water in the pipe group can impact the valve core under the guidance of the water pump, so that the valve core moves from the first position to the second position, thereby making the second open end of the pipe group conductive, and the water in the water storage tank can enter the clean water tank of the cleaning robot through the pipe group. After the water is full or the water storage tank is short of water, the water pump is turned off, and the valve core is restored from the second position to the first position under the action of the reset member, so that the second open end of the pipe group is closed, so as to intercept the water flow in the pipe group in the inner cavity of the pipe group, so as to avoid the remaining water flow from the second open end of the pipe group due to vibration.

[0030] As described in the background art, when the clean water tank of the cleaning robot is full, the water pump is turned off, and the water originally flowing in the water filling pipe is left in the water filling pipe due to the lack of driving force of the water pump. When the cleaning robot is separated from the base station, the base station will vibrate slightly due to the interaction force. This slight vibration will generate driving force for the water remaining in the water filling pipe, causing it to flow out of the water filling pipe.

[0031] In response to the above technical problems, the inventor of the present application thought of connecting a one-way valve in series on the water-filling pipe. However, due to users' demand for miniaturization of household appliances, the size of the cleaning robot and the base station is generally made relatively small, and the size of the cross-section of the water-filling pipe is also relatively small. Since the one-way valve needs to be installed in the inner cavity of the water-filling pipe, and the elastic coefficient of the spring in the one-way valve needs to match the water pump, etc., there are limited models of one-way valves that meet the requirements on the market. And the area of ​​the cross-section of the inner cavity of the one-way valve that meets the requirements is generally small, which will cause the water-filling flow rate to be severely weakened, affecting the water-filling speed and poor user experience. Therefore, the inventor of the present application thought of integrating the one-way valve with the water-filling pipe to maximize the space available for water flow.

[0032] In view of this, an embodiment of the present application provides a cleaning base station and a cleaning device, which connect the water tank of the cleaning base station and the clean water tank of the cleaning robot through a pipe group, and after the water pump is turned off, the second open end of the pipe group away from the water tank is closed by a reset member and a valve core to retain water in the pipe group so that it will not flow out from the second open end of the pipe group due to the vibration generated by the base station.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0034] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0035] Figure 1 A schematic diagram of a cleaning device provided in an embodiment of the present application. Figure 1 , a cleaning device provided in an embodiment of the present application may include a cleaning base station and a cleaning robot 3000. The cleaning robot 3000 (also referred to as a sweeping robot, a mopping robot, a washing and sweeping robot, an intelligent robot, a mobile robot, an automatic sweeper, an intelligent vacuum cleaner, etc.) is an intelligent appliance with a clean water tank and capable of completing cleaning tasks such as sweeping, vacuuming, and mopping. The cleaning robot 3000 can be remotely controlled by a user or can complete floor cleaning tasks in a room by itself according to certain set rules.

[0036] The cleaning base station can be used for the cleaning robot 3000 to dock, and can provide the cleaning robot 3000 with services such as water replenishment, charging, and drainage. Figure 1 The cleaning base station may include a body 2000 and a flow guide assembly 1000. The body 2000 may include a water storage tank, and the water storage tank may include a water inlet and a water outlet. The water inlet may be connected to a water pipe. When the water storage tank needs to be replenished with water, water in the water pipe may flow into the water storage tank through the water inlet; or, a user may manually add water to the water storage tank from the water inlet.

[0037] The first end of the flow guide component 1000 can be connected to the water outlet of the water storage tank, and the second end of the flow guide component 1000 can be used to connect to the clean water tank of the cleaning robot 3000. Figure 2 An exploded view of a flow guide assembly provided in an embodiment of the present application is shown in FIG. Figure 1 and Figure 2The flow guide assembly 1000 may include a pipe set 100, and the pipe set 100 may have a first open end and a second open end. The first open end of the pipe set 100 may be connected to the water outlet of the water storage tank, and the second open end of the pipe set 100 may be used to connect to the clean water tank of the cleaning robot 3000.

[0038] When the clean water tank of the cleaning robot 3000 is short of water, the cleaning robot 3000 may move to the cleaning base station and connect the clean water tank to the second open end of the pipe group 100. The clean water tank may be directly connected to the second open end of the pipe group 100, or the cleaning robot 3000 may include a water supply pipe, and the clean water tank may be indirectly connected to the second open end of the pipe group 100 through the water supply pipe. In addition, the cleaning base station may include a water pump, which may be arranged in the pipe group 100; or the cleaning robot 3000 may include a water pump, which may be arranged in the water supply pipe.

[0039] After the clean water tank and the water storage tank are indirectly connected through the pipe group 100, the water pump is started, and the water stored in the water storage tank can be transferred to the clean water tank through the inner cavity of the pipe group 100 under the guidance of the water pump. When the clean water tank is full or the water storage tank is short of water, the water pump is turned off.

[0040] Figure 3 for Figure 2 A partial perspective cutaway view of a flow guide assembly is shown. Figure 2 and Figure 3 In order to prevent the water remaining in the pipe assembly 100 from flowing out due to the vibration of the base station after the water pump is turned off, the flow guide assembly 1000 provided in the embodiment of the present application may also include a valve core 200 and a reset member 300. The valve core 200 may be movably arranged in the inner cavity of the pipe assembly 100, and the valve core 200 may have a first position and a second position. The reset member 300 may be connected to the valve core 200, and the reset member 300 may provide a reset force for the valve core 200 to move from the second position to the first position.

[0041] When the water pump is in the on state, the water flow in the pipe group 100 can impact the valve core 200 under the guidance of the water pump. The impact force of the water flow on the valve core 200 is greater than the resetting force of the resetting member 300 on the valve core 200, so that the valve core 200 can be in the second position, thereby making the second open end of the pipe group 100 conductive, and then the water in the water storage tank can enter the clean water tank of the cleaning robot 3000 through the pipe group 100.

[0042] When the water pump is in the closed state, the water flow in the pipe set 100 loses power, and the impact force of the water flow on the valve core 200 is smaller than the restoring force of the restoring member 300 on the valve core 200, so that the valve core 200 is in the first position, and then the second open end of the pipe set 100 is closed to intercept the remaining water flow in the inner cavity of the pipe set 100, and prevent the remaining water flow from flowing out of the second open end of the pipe set 100 due to vibration.

[0043] Optionally, the tube set 100 may include a take-out tube 120, one of the open ends of which may form the second open end of the tube set 100, that is, one of the open ends of the take-out tube 120 may be used to connect to the clean water tank of the cleaning robot 3000. In addition, the valve core 200 may be movably disposed in the inner cavity of the take-out tube 120. When the valve core 200 is in the first position, the valve core 200 may close the take-out tube 120; when the valve core 200 is in the second position, the valve core 200 may open the take-out tube 120.

[0044] The valve core 200 can slide or rotate in the access pipe 120 to open and close the access pipe 120. The following first describes how the valve core 200 opens and closes the access pipe 120 in a sliding manner.

[0045] Figure 4 for Figure 2 A cross-sectional view of the guide assembly is shown. Figure 4 , the receiving pipe 120 may have a first lumen 1211 and a second lumen 1221 sequentially arranged along the axial direction of the receiving pipe 120. When adding water, the second lumen 1221 is closer to the clean water tank of the cleaning robot 3000 than the first lumen 1211. And the inner wall of the first lumen 1211 is closer to the axis a of the receiving pipe 120 than the inner wall of the second lumen 1221. In other words, the first orthographic projection of the inner wall of the first lumen 1211 along the axis a of the receiving pipe 120 on the projection plane is located on the inner side of the second orthographic projection of the inner wall of the second lumen 1221 along the axis a of the receiving pipe 120 on the projection plane. Among them, the projection plane is an imaginary plane perpendicular to the axis a of the receiving pipe 120.

[0046] For example, when the cross-section of the first lumen 1211 and the cross-section of the second lumen 1221 are both circular, the radius of the cross-section of the first lumen 1211 is smaller than the radius of the cross-section of the second lumen 1221 .

[0047] Optionally, the first tubular cavity 1211 and the second tubular cavity 1221 may be formed by two tube bodies nested with each other. Specifically, the receiving tube 120 may include a first tubular body 121 and a second tubular body 122. The first tubular body 121 may have a first tubular cavity 1211, and at least a portion of the first tubular body 121 may be embedded in the inner cavity of the second tubular body 122. At least a portion of the second tubular body 122 may be longer than the first tubular body 121 and may have a second tubular cavity 1221, that is, the length of the first tubular body 121 located in the inner cavity of the second tubular body 122 is shorter than that of the second tubular body 122, and the inner cavity of the portion of the second tubular body 122 that grows out of the first tubular body 121 may form the second tubular cavity 1221.

[0048] It should be noted that the first tube body 121 and the second tube body 122 can be integrally formed. Alternatively, for the purpose of installation and maintenance, the first tube body 121 and the second tube body 122 can be two independent components. Optionally, in order to limit the position of the first tube body 121 in the second tube body 122, the outer tube wall of the first tube body 121 can be provided with a first limiting portion 510, and the inner tube wall of the second tube body 122 can be provided with a second limiting portion 520, and the first limiting portion 510 and the second limiting portion 520 can be matched in a concave-convex manner. Among them, the first limiting portion 510 can be as follows Figure 4 The second limiting portion 520 may be as shown in FIG. Figure 4 Alternatively, the first limiting portion 510 may be a groove, and the second limiting portion 520 may be a protrusion. Of course, in order to install the first tube body 121 and the second tube body 122, at least one of the first tube body 121 and the second tube body 122 may have elasticity, so that when the first tube body 121 and the second tube body 122 are assembled, a certain elastic deformation is generated at the first limiting portion 510 and the second limiting portion 520.

[0049] In addition, optionally, in order to facilitate the removal of the first tube body 121, the first tube body 121 may be elastic, and one end of the first tube body 121 may be provided with an annular bifurcated groove 1212. The notch of the bifurcated groove 1212 may be flush with the end surface of the first tube body 121, and there is a distance between the notch and the inner tube wall of the first tube body 121, and between the notch and the outer tube wall of the first tube body 121. In this way, the first tube body 121 may be formed into a main body 1213 and a split part 1214 by the bifurcated groove 1212, wherein the split part 1214 may be closer to the axis of the first tube body 121. The user can use the split part 1214 to remove the first tube body 121 from the second tube body 122.

[0050] The valve core 200 is slidably disposed in the inner cavity of the receiving pipe 120 along the axis a of the receiving pipe 120. Figure 4 When the valve core 200 is in the first position, the valve core 200 can block the first lumen 1211. When the valve core 200 moves from the first position to the second position, the valve core 200 can slide in the inner cavity of the outlet tube 120 along a preset direction to open the first lumen 1211, thereby connecting the first lumen 1211 with the second lumen 1221. The preset direction is the direction from the first lumen 1211 to the second lumen 1221.

[0051] The valve core 200 may block the first lumen 1211 in the following ways:

[0052] In one possible blocking method, such as Figure 4 As shown, the valve core 200 is Figure 4 As shown in the first position, at least a portion of the valve core 200 can be embedded in the first lumen 1211 and block the first lumen 1211 .

[0053] In order to facilitate sealing, the flow guide assembly 1000 may optionally include a second sealing member 420, which may be sleeved on the outer side of the valve core 200. Figure 4 When in the first position, the second sealing member 420 can be sealed between the valve core 200 and the inner tube wall of the first tube body 121. The second sealing member 420 can be made of a material having a certain elastic deformation ability, such as rubber.

[0054] In addition, to facilitate the sliding of the valve core 200 in the first lumen 1211, optionally, at least part of the inner wall of the first lumen 1211 is inclined along one end of a preset direction toward the axis a away from the outlet tube 120. The preset direction is the direction from the first lumen 1211 to the second lumen 1221.

[0055] In another possible blocking method, such as Figure 5 As shown in FIG. 1 , the outer edge of the valve core 200 is farther from the axis a of the outlet tube 120 than the inner wall of the first tube cavity 1211. And the outer edge of the valve core 200 is closer to the axis a of the outlet tube 120 than the inner wall of the second tube cavity 1221, so that a channel for water flow can be formed between the valve core 200 and the inner wall of the second tube cavity 1221. Figure 5 When in the first position as shown, the end surface of the valve core 200 can block one side of the first tube cavity 1211.

[0056] Optionally, the flow guide assembly 1000 may include a third sealing member 430, which may be disposed on the end surface of the valve core 200. Figure 5 When in the first position, the third sealing member 430 can be sealed between the end surface of the valve core 200 and the end surface of the first tube body 121. The third sealing member 430 can be made of a material having a certain elastic deformation ability, such as rubber.

[0057] refer to Figure 4 and Figure 5 In order to make the valve core 200 slide more smoothly in the outlet pipe 120, optionally, a first sliding portion 710 may be provided in the inner cavity of the outlet pipe 120, and the valve core 200 may be provided with a second sliding portion 720, and the second sliding portion 720 may be slidably disposed on the first sliding portion 710 along the axial direction of the outlet pipe 120.

[0058] In one exemplary embodiment, reference Figure 4, the first sliding part 710 may be a fixed block. The first sliding part 710 may be fixed in the inner cavity of the receiving pipe 120, and the first sliding part 710 may be located on one side of the valve core 200 (along the axial direction of the receiving pipe 120). A space for water flow may be formed between the first sliding part 710 and the inner tube wall of the tube assembly 100. In addition, the first sliding part 710 may have a sliding hole arranged along the axial direction of the receiving pipe 120. The second sliding part 720 may be arranged at one end of the valve core 200 along the axial direction of the receiving pipe 120, and the second sliding part 720 may be penetrated through the sliding hole and may slide in the sliding hole.

[0059] In another exemplary embodiment, referring to Figure 5 The first sliding part 710 can be disposed on the inner wall of the outlet pipe 120, and the second sliding part 720 can be disposed on the outer edge of the valve core 200. The second sliding part 720 and the first sliding part 710 can be matched with each other in a concave-convex manner, and the second sliding part 720 can be slidably disposed on the first sliding part 710 along the axial direction of the outlet pipe 120. Figure 5 The second sliding portion 720 may be as shown in FIG. Figure 5 Alternatively, the first sliding portion 710 may be a protrusion and the second sliding portion 720 may be a groove.

[0060] As mentioned above, the reset member 300 can provide a reset force for the valve core 200 to move from the second position to the first position. Figure 4 and Figure 5 When sliding along the axis a of the extension tube 120 , in order to improve the restoring effect, the restoring member 300 may be a linear spring, and the restoring member 300 may have elastic deformation along the axis a of the extension tube 120 .

[0061] In order to install the reset member 300 , a mounting member for installing the reset member 300 may be provided in the inner cavity of the outlet tube 120 . The mounting member may be located on one side of the valve core 200 (along the axial direction of the outlet tube 120 ), and the reset member 300 may be clamped between the mounting member and the valve core 200 . Figure 4 In the embodiment, the first sliding portion 710 constitutes a mounting member, and the reset member 300 can abut between an end surface of the first sliding portion 710 and an end surface of the valve core 200 . Figure 5 In the embodiment, the mounting member is a protrusion 900 disposed on one side of the valve core 200 and disposed on the inner wall of the second tube cavity 1221. The reset member 300 can be abutted between the end surface of the protrusion 900 and the end surface of the valve core 200. It can be understood that the longer the protrusion 900 is, the greater the obstruction to the water flow in the second tube cavity 1221. In order to ensure that the water flow in the second tube cavity 1221 flows smoothly when adding water, the reset member 300 can be as follows: Figure 5 A taper is shown to reduce the length of the protrusion 900 .

[0062] The above Figure 2-Figure 5 As an example, the valve core 200 is described to open and close the outlet pipe 120 in a sliding manner. Figure 6-Figure 8 The following describes how the valve core 200 opens and closes the outlet pipe 120 in a rotating manner as an example.

[0063] refer to Figure 6 and Figure 7 The flow guide assembly 1000 provided in the embodiment of the present application may further include a rotating shaft 800. The valve core 200 may be a plate body, and the valve core 200 may be rotatably disposed in the inner cavity of the outlet pipe 120 via the rotating shaft 800. Figure 6 When the valve core 200 is in the first position as shown in FIG. 1 , the cross section of the valve core 200 is parallel to the cross section of the access pipe 120, and the valve core 200 can block the access pipe 120. Figure 7 When the valve core 200 is in the second position, an angle may be formed between the cross section of the valve core 200 and the cross section of the outlet pipe 120 , and a space for water to flow through may be formed between the valve core 200 and the inner wall of the outlet pipe 120 .

[0064] refer to Figure 8 In order to improve the reset effect, the valve core 200 may optionally be provided with a through hole 210 for the rotating shaft 800 to pass through. The inner hole wall of the through hole 210 may be provided with an abutment portion 220. The reset member 300 may be a torsion spring, which may be sleeved on the outer side of the rotating shaft 800, and the end of the reset member 300 may abut against the abutment portion 220, so that the reset member 300 can provide a torsional reset force for the valve core 200.

[0065] refer to Figure 3 and Figure 4 In order to assemble and disassemble the valve core 200, the valve core 200 can be arranged at the end of the access pipe 120. In order to intercept most of the water flow in the pipe group 100, the valve core 200 is arranged near the second open end of the pipe group 100. Therefore, the pipe group 100 may also include an access pipe 110 connected to the access pipe 120. One end of the access pipe 110 away from the access pipe 120 may form the first open end of the pipe group 100. Specifically, the access pipe 110 may have a first end and a second end, the first end of the access pipe 110 may be connected to the water storage tank, and the second end of the access pipe 110 may be connected to the access pipe 120.

[0066] In order to prevent the access pipe 110 from affecting the movement of the valve core 200 in the access pipe 120, the second end of the access pipe 110 can be sleeved on the outside of the access pipe 120. The access pipe 110 and the access pipe 120 can be connected by threaded connection, snap connection, or connection through fasteners such as clamps.

[0067] In addition, in order to limit the relative position of the access pipe 110 and the access pipe 120, the access pipe 120 may optionally have a first end surface close to the access pipe 110. The access pipe 110 may have an inner step surface 111, which may face the first end surface of the access pipe 120 and limit the position of the first end surface of the access pipe 120.

[0068] Exemplary, reference Figure 3 and Figure 4 In order to form the inner step surface 111, the access pipe 110 may include a small pipe section 112 and a large pipe section 113 that are connected in sequence. The inner pipe wall of the small pipe section 112 is closer to the axis of the access pipe 110 than the inner pipe wall of the large pipe section 113. In other words, the inner pipe wall of the small pipe section 112 is located on the inner side of the fourth orthographic projection of the inner pipe wall of the large pipe section 113 along the axis of the access pipe 110 on the projection plane along the third orthographic projection of the inner pipe wall of the large pipe section 113 on the projection plane along the axis of the access pipe 110. The projection plane is an imaginary plane perpendicular to the axis of the access pipe 110. In addition, the large pipe section 113 may be sleeved on the outer side of the access pipe 120, and the inner step surface 111 may be formed at the connection between the large pipe section 113 and the small pipe section 112.

[0069] In order to seal the access pipe 110 and the access pipe 120 , the flow guide assembly 1000 may optionally further include an annular first seal 410 . The first seal 410 may be disposed between the first end surface and the inner step surface 111 .

[0070] The following describes the cleaning base station and cleaning equipment provided in the embodiments of the present application in combination with specific application scenarios.

[0071] During the holidays, Xiaoxiang was in the kitchen preparing a sumptuous dinner for everyone. During the process of washing vegetables, preparing vegetables, cutting vegetables, and cleaning dishes, a lot of liquid spilled on the kitchen floor. As Xiaoxiang walked around in the kitchen, the spilled liquid mixed with the dust and sludge on the floor, forming stubborn stains that were difficult to clean.

[0072] After Xiaoxiang finished her work, she found that the kitchen floor was covered with various stains that were difficult to clean. Figure 1 The cleaning robot 3000 (shown) issues an instruction to clean the kitchen floor. Based on the instruction, the cleaning robot 3000 turns on the laser radar and uses the laser radar to detect the environment of the kitchen. The laser radar can generate a dot cloud based on the environment of the kitchen, and the cleaning robot 3000 can build a model of the kitchen based on the point cloud map, and then the cleaning robot 3000 uses the path planning algorithm to calculate the best cleaning path. At the same time, the cleaning robot 3000 can also judge the cleaning status of the ground based on the point cloud map. For example, when the laser hits the water surface, most of the laser will be absorbed by the water, and a small part of the laser will be reflected by the mirror, resulting in the laser radar being unable to receive the echo, that is, the water surface cannot generate a dot cloud.

[0073] Using the above principle, the cleaning robot 3000 determines that the floor to be cleaned is covered with liquid, so the cleaning robot 3000 divides the deep cleaning instruction into two steps. The first step: recovering sewage; the second step: wiping the floor with a rag soaked in water in the clean water tank.

[0074] When the clean water tank is short of water, the cleaning robot 3000 can move to the cleaning base station and connect its clean water tank to the second open end of the pipe group of the cleaning base station. Figure 2-Figure 7 , the water pump starts, the valve core 200 is impacted by the water flow in the pipe group 100 and moves from the first position to the second position, and the water stored in the water storage tank of the cleaning base station can be transferred to the clean water tank through the inner cavity of the pipe group 100 under the guidance of the water pump. When the clean water tank is full, the water pump is turned off, and the cleaning robot 3000 leaves the cleaning base station and returns to the kitchen to continue cleaning the kitchen floor. At the same time, the valve core 200 moves from the second position to the first position due to the reset force provided by the reset member 300, so as to retain the water flow in the pipe group 100 in the inner cavity of the pipe group 100, thereby preventing the remaining water flow from flowing out of the pipe group 100 due to vibration.

[0075] When Xiaoxiang came to the kitchen after dinner, she found that the kitchen floor had been cleaned and looked as bright as new, and the Cleaning Robot 3000 was quietly charging at the cleaning base station. It can be said that it had done its job and left without any fame or contribution.
