Description

Technical Field

[0001] The present invention relates to the field of cleaning equipment, and in particular to a cleaning system. Background Art

[0002] A cleaning robot is an automated cleaning device that automatically cleans dust, garbage, stains, etc. on the ground. The cleaning robot includes a dust box assembly that can store the dust collected by the cleaning robot.

[0003] When there is a lot of wet dust on the ground, the cleaning robot will collect some of the wet dust and store it in the dust box assembly. After the wet dust dries in the dust box assembly, it will adhere to the inner wall of the dust box assembly, making it more difficult to clean the inside of the dust box assembly. Summary of the Invention

[0004] An embodiment of the present invention provides a cleaning system to improve the cleaning efficiency of the interior of a storage box assembly of a cleaning robot.

[0005] An embodiment of the present invention provides a cleaning system, which includes: a cleaning robot including a storage box assembly; and a cleaning base station for maintaining the cleaning robot, the cleaning base station including a water injection assembly. When the cleaning robot is in a maintenance state, the water injection assembly injects liquid into the storage box assembly to clean the storage box assembly.

[0006] According to the aforementioned embodiment of the present invention, the storage box assembly includes: a box body, the box body includes a dirt collecting chamber and a first through hole extending from the inner surface of the box body to the dirt collecting chamber; and a one-way valve assembly, arranged in the first through hole, the one-way valve assembly being configured to allow liquid to be input from the outside into the dirt collecting chamber.

[0007] According to any of the aforementioned embodiments of the present invention, the one-way valve assembly includes: a sealing sleeve, which is at least partially sealed and connected to the first through hole, and the sealing sleeve includes a channel extending along the axial direction of the sealing sleeve; a piston, which includes a movable block, and the movable block can move closer to or away from the channel along the axial direction of the sealing sleeve; and an elastic member, which elastically connects the piston to the sealing sleeve.

[0008] According to any of the aforementioned embodiments of the present invention, the one-way valve assembly includes a first state and a second state. In the first state, the elastic member causes the movable block to block the channel; in the second state, the movable block is away from the channel, allowing liquid to flow through the channel.

[0009] According to any of the aforementioned embodiments of the present invention, the sealing bushing includes: a sealing portion, which is sealed and connected to the first through hole, and the channel is arranged in the sealing portion; and a spray portion, which is connected to the sealing portion, and the spray portion is located in the dirt collecting chamber. The spray portion includes a accommodating cavity and a plurality of second through holes, and the accommodating cavity is connected to the channel. The movable block is movably arranged in the accommodating cavity along the axial direction of the sealing bushing, and the plurality of second through holes are distributed on the circumferential side wall of the spray portion, and connects the outside of the spray portion with the accommodating cavity.

[0010] According to any of the aforementioned embodiments of the present invention, the plurality of second through holes are located at preset positions on the circumferential side wall of the spray portion along the axial direction, so that in the first state, the circumferential side wall of the movable block blocks the plurality of second through holes.

[0011] According to any of the aforementioned embodiments of the present invention, the cross-sectional dimension of the outer circumference of the spray portion perpendicular to the axial direction is larger than the cross-sectional dimension of the outer circumference of the sealing portion perpendicular to the axial direction, so that the spray portion and the sealing portion form a stepped structure.

[0012] According to any of the aforementioned embodiments of the present invention, the sealing portion is an elastic sealing portion.

[0013] According to any of the aforementioned embodiments of the present invention, the channel has a first opening toward the movable block, the sealing bushing also includes a first abutment portion, the first abutment portion extends radially inward from the inner wall surface of the channel at the first opening, and the piston also includes: a second abutment portion located in the channel; and a connecting rod connecting the second abutment portion to the movable block, wherein the elastic member elastically connects the first abutment portion to the second abutment portion.

[0014] According to any of the aforementioned embodiments of the present invention, the cleaning robot also includes: a cover assembly, which is arranged on the storage box assembly, the cover assembly includes a third through hole corresponding to the position of the first through hole of the storage box assembly and a dust plug, the dust plug is arranged in the third through hole, and the dust plug includes a dust port that can switch between open and closed states.

[0015] According to any of the aforementioned embodiments of the present invention, the water injection assembly includes: a liquid storage tank; a liquid conveying device, the liquid conveying device includes a liquid inlet and a liquid outlet, the liquid inlet is connected to the liquid storage tank; a nozzle, connected to the liquid outlet; and a nozzle movable device, including a mounting portion and a movable portion, the movable portion can move relative to the mounting portion, the movable portion is connected to the nozzle, so that the movable portion can drive the nozzle to move.

[0016] According to any of the aforementioned embodiments of the present invention, the cleaning base station further includes: a shell; and an alignment sensor, which is arranged on the outer surface of the shell, the alignment sensor is used to align with the cleaning robot, and the water injection component is connected to the shell, and the water injection component is configured to inject liquid into the storage box component when the alignment sensor completes alignment with the cleaning robot.

[0017] According to an embodiment of the present invention, the cleaning system includes a water injection assembly in the cleaning base station. When the cleaning robot is in operation, the storage box assembly stores dirt. When maintaining the cleaning robot, the cleaning base station can use the water injection assembly to inject liquid into the storage box assembly, using the liquid to clean the storage box assembly, thereby improving the cleaning effect and cleaning speed of the storage box assembly.

[0018] In some optional embodiments, the storage box assembly includes a box body provided with the dirt collecting chamber and a one-way valve assembly. The box body includes a first through hole, and the one-way valve assembly is provided in the first through hole, and the one-way valve assembly is configured to allow liquid to be input from the outside into the dirt collecting chamber. When the cleaning robot is in working state, the one-way valve assembly separates the dirt collecting chamber from the outside, thereby preventing dust in the dirt collecting chamber from escaping from the first through hole, ensuring the normal operation of the storage box assembly and the cleaning robot. When the cleaning base station maintains the cleaning robot, liquid can be input into the dirt collecting chamber through the one-way valve assembly, and the dust on the inner wall of the dirt collecting chamber can be cleaned with the liquid, thereby improving the cleaning effect and cleaning rate of the interior of the storage box assembly.

[0019] In some optional embodiments, the one-way valve assembly includes a sealing sleeve, a piston, and an elastic member. The elastic member elastically connects the piston to the sealing sleeve. In a first state, the elastic member causes the movable block to block the passage. Specifically, the elastic member has an elastic restoring force that pulls the movable block toward the passage to block the passage. By providing the elastic member, the initial state of the one-way valve assembly is the first state in which the movable block blocks the passage. This ensures that the one-way valve assembly maintains strong sealing performance except when the storage box assembly requires maintenance, thereby improving the reliability of the storage box assembly during non-maintenance periods.

[0020] In some optional embodiments, the sealing bushing includes a sealing portion and a spray portion, and the spray portion includes a accommodating chamber and a plurality of second through holes. The cross-sectional shape of the movable block perpendicular to the axial direction matches the cross-sectional shape of the accommodating chamber perpendicular to the axial direction, so that a dynamic seal is formed between the circumferential side wall of the movable block and the accommodating chamber. In the second state, the movable block and the spray portion are enclosed to form a spray chamber, and the liquid can enter the spray chamber through the channel and be sprayed into the sewage collecting chamber through the plurality of second through holes. The plurality of second channels have the effect of further enhancing the flow pressure of the liquid, so that the flow rate of the liquid sprayed from the plurality of second channels is higher, thereby flushing the sewage collecting chamber and further improving the cleaning effect of the sewage collecting chamber.

[0021] In some optional embodiments, multiple second through-holes are located at predetermined positions on the circumferential sidewall of the spray portion along the axial direction, so that in the first state, the circumferential sidewall of the movable block blocks the multiple second through-holes. Therefore, in the first state, the surface of the movable block facing the channel blocks the channel, and the circumferential sidewall of the movable block simultaneously blocks the multiple second through-holes. This creates two cutoff barriers along the liquid flow path at the one-way valve assembly in the first state. Even if there is leakage in the channel, the leakage will be blocked at the multiple second through-holes, further improving the sealing performance of the one-way valve assembly in the first state.

[0022] In some optional embodiments, the cross-sectional dimension of the outer circumference of the spray portion perpendicular to the axial direction is greater than the cross-sectional dimension of the outer circumference of the sealing portion perpendicular to the axial direction, so that the spray portion and the sealing portion form a stepped structure. When the one-way valve assembly is assembled into the first through hole of the box body, the stepped structure formed by the spray portion and the sealing portion can serve as a mounting position structure or a retaining structure, preventing the portion of the spray portion having the multiple second through holes from extending into the first through hole, thereby preventing the inner wall of the first through hole from blocking the second through holes. This makes it easier to assemble the one-way valve assembly into the first through hole to the appropriate depth.

[0023] In some optional embodiments, the sealing portion is an elastic sealing portion, so that the outer peripheral side wall of the sealing portion can be in closer contact with the inner wall surface of the first through hole, thereby improving the sealing effect between the two.

[0024] In some optional embodiments, the channel has a first opening toward the movable block, the sealing sleeve further includes a first abutment extending radially inward from the inner wall surface of the channel at the first opening, and the piston further includes a second abutment and a connecting rod. An elastic member elastically connects the first abutment to the second abutment. By elastically connecting the second abutment of the piston to the first abutment of the sealing sleeve, the movable block is configured to block the channel by default, while also limiting the axial movement of the piston, thereby preventing the piston from completely disengaging from the sealing sleeve and falling during axial movement.

[0025] In some optional embodiments, the cleaning robot further includes a cover assembly, the cover assembly including a third through hole and a dust plug, the dust plug being disposed within the third through hole and including a switchable dust port. When the cleaning robot is in a maintenance mode, the dust port can be opened to facilitate injection of liquid into the one-way valve assembly. When the cleaning robot is in an operating mode, the dust port is closed to reduce the amount of dust that falls into the one-way valve assembly and improve the reliability of the one-way valve assembly.

[0051] An embodiment of the present invention provides a cleaning system. The cleaning system may include a cleaning robot and a cleaning base station. The cleaning base station is used to maintain the cleaning robot.

[0052] Figure 1 This is a three-dimensional schematic diagram of an embodiment of the cleaning system of the present invention in a maintenance state. Figure 2 FIG1 is a perspective diagram of an embodiment of a cleaning system of the present invention in a non-maintenance state. The cleaning system includes a cleaning robot 1000 and a cleaning base station 2000.

[0053] The cleaning robot 1000 includes a storage box assembly. The storage box assembly can be a dust box assembly, a dirty water box assembly, or the like. In this embodiment, the dust box assembly is used as an example to describe the storage box assembly, which can store dust collected by the cleaning robot. The storage box assembly can be internal to the cleaning robot 1000, for example, covered by a cover assembly. In some embodiments, the storage box assembly has a dirt collection chamber.

[0054] The cleaning base station 2000 includes a water injection assembly 800. When the cleaning robot 1000 is in the maintenance mode, the water injection assembly 800 injects liquid into the dirt collection chamber of the storage box assembly to clean the storage box assembly. The water injection assembly 800 can, for example, inject clean water into the dirt collection chamber. In other embodiments, the water injection assembly 800 can inject other cleaning liquids with cleaning functions into the dirt collection chamber.

[0055] According to an embodiment of the present invention, the cleaning system includes a cleaning robot 1000 and a cleaning base station 2000. When the cleaning base station 2000 maintains the cleaning robot 1000, liquid can be injected into the storage box assembly through the water injection assembly 800, and the dust in the storage box assembly or the dirty liquid in the storage box assembly can be cleaned by using the liquid, thereby improving the cleaning effect and cleaning rate of the interior of the storage box assembly.

[0056] Figure 3 Schematic diagram of a cleaning robot in one embodiment of the cleaning system of the present invention. Figure 4 This is a three-dimensional schematic diagram of a storage box assembly of a cleaning robot in one embodiment of a cleaning system of the present invention. Figure 5This is a schematic exploded perspective view of a storage box assembly of a cleaning robot in one embodiment of a cleaning system of the present invention.

[0057] In this embodiment, the cleaning robot 1000 includes a cleaning robot body and a water tank assembly detachably connected to the cleaning robot body, and the storage box assembly 100 is disposed on the water tank assembly. In other embodiments, the storage box assembly 100 can be disposed on the cleaning robot 1000 through other connection methods.

[0058] The storage box assembly 100 includes a box body 110 and a one-way valve assembly 130. In this embodiment, the box body 110 includes a dirt collection chamber 111. The box body 110 also includes a first through hole 112 extending from the outer surface of the box body 110 to the dirt collection chamber 111. The one-way valve assembly 130 is disposed in the first through hole 112 and is configured to allow external liquid to enter the dirt collection chamber 111.

[0059] In the above embodiment, the storage box assembly 100 of the cleaning robot 1000 includes a one-way valve assembly 130, which is configured to allow liquid to be input from the outside into the dirt collecting chamber 111. When the cleaning robot 1000 is in operation, the one-way valve assembly 130 separates the dirt collecting chamber 111 from the outside, thereby preventing dust in the dirt collecting chamber 111 from escaping from the first through hole 112, thereby ensuring the normal operation of the storage box assembly 100 and the cleaning robot 1000. When the cleaning base station 2000 is maintaining the cleaning robot 1000, liquid can be input into the dirt collecting chamber 111 through the one-way valve assembly 130, and the dust on the inner wall of the dirt collecting chamber 111 can be cleaned with the liquid, thereby improving the cleaning effect and cleaning rate of the interior of the storage box assembly 100.

[0060] In this embodiment, the box body 110 includes a box body main body 110a and a box body top cover 110b. The dirt collecting chamber 111 is disposed in the box body main body 110a, and the box body top cover 110b covers the dirt collecting chamber 111. Optionally, one side of the box body top cover 110b is rotatably connected to the box body main body 110a. When the box body top cover 110b is rotated, the box body top cover 110b can cover the dirt collecting chamber 111 or expose the top opening of the dirt collecting chamber 111. When one side of the box body top cover 110b is rotatably connected to the box body main body 110a, the other side of the box body top cover 110b can be detachably connected to the box body main body 110a, for example, by a snap connection.

[0061] The first through hole 112 may be provided at the top of the box body 110. For example, in the above embodiment, the first through hole 112 is provided at the box body top cover 110b.

[0062] In some embodiments, the box body 110 may include a dust inlet and a dust outlet, both of which are connected to the dirt collection chamber 111. External dust enters the dirt collection chamber 111 through the dust inlet and is collected. When the storage box assembly 100 is in the maintenance state, the dust collected in the dirt collection chamber 111 can be discharged through the dust outlet.

[0063] When the storage box assembly 100 is in the dust collection state, the one-way valve assembly 130 isolates the dirt collection chamber 111 from the outside, thereby preventing dust in the dirt collection chamber 111 from escaping through the first through hole 112, ensuring the normal operation of the storage box assembly 100. When the storage box assembly 100 is in the maintenance state, the water injection assembly 800 injects liquid into the dirt collection chamber 111 through the one-way valve assembly 130, using the liquid to clean the dust on the inner wall of the dirt collection chamber 111, thereby improving the cleaning effect and cleaning speed of the interior of the storage box assembly 100.

[0064] Figure 6 This is a three-dimensional half-section schematic diagram of a one-way valve assembly in an embodiment of the cleaning system of the present invention. Figure 7 The figure is a schematic diagram of a three-dimensional decomposition of a one-way valve assembly in an embodiment of a cleaning system of the present invention. In some embodiments, the one-way valve assembly 130 includes a sealing sleeve 131, a piston 132, and an elastic member 133. The sealing sleeve 131 is at least partially sealed and connected to the first through hole 112. Specifically, at least a portion of the outer peripheral surface of the sealing sleeve 131 is sealed and connected to the first through hole 112. The sealing sleeve 131 includes a channel T1 extending along the axial direction of the sealing sleeve 131. The piston 132 includes a movable block 1321, which can move closer to or away from the channel T1 along the axial direction of the sealing sleeve 131. The elastic member 133 elastically connects the piston 132 to the sealing sleeve 131.

[0065] Optionally, the one-way valve assembly 130 includes a first state and a second state. In the first state, the elastic member 133 causes the movable block 1321 to block the channel T1. In the second state, the movable block 1321 is away from the channel T1, allowing liquid to flow through the channel T1.

[0066] In the above embodiment, elastic member 133 elastically connects piston 132 to sealing sleeve 131. In the first state, elastic member 133 causes movable block 1321 to block passage T1. Specifically, elastic member 133 has an elastic restoring force that pulls movable block 1321 to block passage T1. By providing elastic member 133, the initial state of one-way valve assembly 130 is the first state in which movable block 1321 blocks passage T1. This ensures that one-way valve assembly 130 maintains a strong sealing performance except during periods when storage box assembly 100 requires maintenance, thereby improving the reliability of storage box assembly 100 during non-maintenance periods.

[0067] In some embodiments, the sealing sleeve 131 includes a sealing portion 1311 and a spray portion 1312. The sealing portion 1311 is sealed and connected to the first through hole 112. Specifically, in this embodiment, the outer peripheral surface of the sealing portion 1311 is sealed and connected to the first through hole 112, and the channel T1 is provided in the sealing portion 1311. The spray portion 1312 is connected to the sealing portion 1311. The spray portion 1312 is located in the dirt collecting chamber 111. The spray portion 1312 includes a accommodating chamber T2 and a plurality of second through holes H2. The accommodating chamber T2 is connected to the channel T1, and the movable block 1321 is movably provided in the accommodating chamber T2 along the axial direction of the sealing sleeve 131. The plurality of second through holes H2 are distributed on the circumferential side wall of the spray portion 1312, and connect the outside of the spray portion 1312 with the accommodating chamber T2.

[0068] In some embodiments, the cross-sectional shape of the movable block 1321, perpendicular to the axial direction, matches the cross-sectional shape of the accommodating chamber T2, perpendicular to the axial direction. In the second state, the movable block 1321 and the spray portion 1312 enclose a spray chamber, allowing liquid to enter the spray chamber through the channel T1 and be sprayed into the sewage collection chamber 111 through the plurality of second through holes H2.

[0069] In the above embodiment, the cross-sectional shape of the movable block 1321 perpendicular to the axial direction matches the cross-sectional shape of the accommodating chamber T2 perpendicular to the axial direction, thereby forming a dynamic seal between the circumferential side wall of the movable block 1321 and the accommodating chamber T2. In the second state, the movable block 1321 and the spray portion 1312 enclose a spray chamber, and liquid can enter the spray chamber through the channel T1 and be sprayed into the sewage collecting chamber 111 through the multiple second through holes H2. The multiple second channels T1 have the effect of further enhancing the flow pressure of the liquid, so that the flow rate of the liquid sprayed from the multiple second channels T1 is higher, thereby flushing the sewage collecting chamber 111 and further improving the cleaning effect of the sewage collecting chamber 111.

[0070] In some embodiments, multiple second through holes H2 are located axially at predetermined positions on the circumferential sidewall of the spray portion 1312, such that in the first state, the circumferential sidewall of the movable block 1321 blocks the multiple second through holes H2. Therefore, in the first state, the surface of the movable block 1321 facing the channel T1 blocks the channel T1, while the circumferential sidewall of the movable block 1321 simultaneously blocks the multiple second through holes H2. This creates two cutoff barriers along the liquid flow path at the one-way valve assembly 130 in the first state. Even if there is leakage in the channel T1, the leakage will be blocked at the multiple second through holes H2, further improving the sealing performance of the one-way valve assembly 130 in the first state.

[0071] In some embodiments, the cross-sectional dimension of the outer circumferential surface of the spray portion 1312 perpendicular to the axial direction is greater than the cross-sectional dimension of the outer circumferential surface of the sealing portion 1311 perpendicular to the axial direction, so that the spray portion 1312 and the sealing portion 1311 form a stepped structure. In this embodiment, the outer circumferential surface of the spray portion 1312 is a cylindrical surface, and the outer circumferential surface of the sealing portion 1311 is a cylindrical surface, wherein the diameter of the outer circumferential surface of the spray portion 1312 is greater than the diameter of the outer circumferential surface of the sealing portion 1311. When the one-way valve assembly 130 is assembled into the first through hole 112 of the box body 110, the stepped structure formed by the spray portion 1312 and the sealing portion 1311 can serve as a mounting structure or a retaining structure, preventing the portion of the spray portion 1312 having the plurality of second through holes H2 from extending into the first through hole 112, thereby preventing the inner wall of the first through hole 112 from blocking the second through holes H2. This makes it easier for the one-way valve assembly 130 to be assembled to the appropriate depth of the first through hole 112.

[0072] In some embodiments, the sealing portion 1311 is an elastic sealing portion. Optionally, the sealing portion 1311 is made of, for example, rubber. By configuring the sealing portion 1311 as an elastic sealing portion, the outer peripheral sidewall of the sealing portion 1311 can more closely contact the inner wall surface of the first through hole 112, thereby improving the sealing effect between the two.

[0073] In some embodiments, the channel T1 has a first opening K1 facing the movable block 1321. The sealing bushing 131 further includes a first abutting portion 1313 extending radially inward from an inner wall surface of the channel T1 at the first opening K1.

[0074] In some embodiments, piston 132 further includes a second abutting portion 1322 and a connecting rod 1323. Second abutting portion 1322 is located within channel T1. Connecting rod 1323 connects second abutting portion 1322 to movable block 1321. Elastic member 133 elastically connects first abutting portion 1313 and second abutting portion 1322. Elastic member 133 is, for example, a spring. In other embodiments, elastic member 133 may also be another elastic member such as a spring.

[0075] By elastically connecting the second abutment portion 1322 of the piston 132 with the first abutment portion 1313 of the sealing sleeve 131, on the one hand, the default state of the movable block 1321 is to block the channel T1, and on the other hand, the axial movement of the piston 132 is limited to prevent the piston 132 from completely separating from the sealing sleeve 131 and falling when moving axially.

[0076] In some embodiments, the channel T1 has a second opening K2 disposed opposite to the first opening K1 . In the second state, external liquid enters the channel T1 from the second opening K2 .

[0077] like Figure 3In some embodiments, the cleaning robot 1000 further includes a cover assembly 200 . The cover assembly 200 is disposed on the storage box assembly 100 .

[0078] Figure 8 This is a perspective schematic diagram of the cover assembly of a cleaning robot in one embodiment of the cleaning system of the present invention. The cover assembly 200 includes a third through-hole 210 corresponding to the first through-hole 112 of the storage box assembly 100, and a dust plug 220. The dust plug 220 is disposed within the third through-hole 210 and includes a switchable dustproof port.

[0079] In some embodiments, the dust plug 220 is made of rubber material, and the dust port is a cross-shaped opening provided on the dust plug 220. Since the rubber dust plug 220 has elastic restoring force, the cross-shaped opening is in a closed state by default. The cross-shaped opening can be opened by other objects, so that the cross-shaped opening is switched to an open state. The dust plug 220 of this embodiment includes a dust port that can switch between open and closed states.
