Embodiments of the present application provide a floor cleaning device. The floor cleaning device includes, for example, an upright floor cleaning device, etc. The specific form of the floor cleaning device described above is not particularly limited in the embodiments of the present application. For convenience of explanation, the upright push-rod type floor cleaning unit will be described as an example.

Referring to fig. 1, a schematic structure of a floor cleaning device 100 according to an embodiment of the present application is shown. The device 100 mainly comprises a cleaning base 1 and an upright body 2; wherein the cleaning base 1 is adapted to move along the floor, the lower part of the upright body 2 is pivotally connected to the cleaning base 1, the upright body 2 being pivotable relative to the cleaning base 1 between an upright storage position and an inclined working position.

The upright body 2 may include a housing 21 and a handle assembly 22 located on an upper side of the housing 21. The casing 21 mainly supports a detachable solution tank 23, a detachable contaminated liquid recovery tank 24 and a suction motor 25.

The floor cleaning apparatus 100 further includes a cleaning liquid supply system for delivering cleaning liquid to the cleaning base and a dirty liquid recovery system for recovering dirty liquid from the floor, which is changed from the used cleaning liquid, and debris on the floor. The cleaning liquid supply system comprises and is defined in part by a solution tank 23, the solution tank 23 being configured for storing cleaning liquid, the cleaning liquid supply system being capable of dispensing cleaning liquid to the cleaning base 1 when the floor cleaning apparatus 100 is in operation. The dirty liquid recovery system includes and is defined in part by a dirty liquid recovery tank 24 and a suction motor 25, the dirty liquid recovery tank 24 storing dirty liquid and debris, the suction motor 25 including a motor and a fan, operation of the suction motor 25 effecting suction of the dirty liquid and debris from the ground into the dirty liquid recovery tank 24.

The cleaning base 1 has a base housing 10 in the shape of a box, the base housing 10 comprising a front 101, a rear 102 and opposite first 103 and second 104 sides. The base housing 1 may be assembled from multiple housings. The bottom of the base housing 1 is provided with a moving wheel 109 which can drive the cleaning base 10 to move back and forth on the floor. The front 101 of the base housing 1 defines a brush cavity 105. The front portion of the brush cavity 105 may have a front opening 106 and the lower portion of the brush cavity 105 has a lower opening 107. The main brush roller 11 is rotatably disposed in the brush chamber 105 around its own brush roller shaft X1, and the front portion of the main brush roller 11 is exposed from the front opening 106 and the lower portion is exposed from the lower opening 107. The lower opening 107 is in fluid communication with the dirty liquid recovery tank 24 to enable dirty liquid and debris on the floor to be sucked into the dirty liquid recovery tank 24 from the lower opening 107 under the suction of the suction motor 25. The first side 103 is provided with a side brush 12, the side brush 12 being arranged at the first side 103 rotatably about a horizontal axis X2, the side brush 12 protruding at least partially laterally beyond the outer contour of the first side 103. In this example, the main brush roller 11 and the side brush 12 may be driven to rotate by the same motor (not shown), and the brush roller shaft X1 of the main brush roller 11 is collinear with the horizontal axis X2 of the side brush 12.

As shown in fig. 2, the lower end of the side brush 12 is substantially flush with the lower end of the brush roller 11, and the main brush roller 11 rotating around the brush roller shaft X1 can clean the floor 500; the side brush 12 rotating around the horizontal axis X2 can clean the wall surface 600 perpendicular to the ground 500, and the lower end of the side brush 12 rotating can brush the junction between the ground 500 and the wall surface 600.

As shown in fig. 3, the cleaning liquid supply system includes a liquid distribution system disposed at the cleaning base 1 in addition to the solution tank 23. In this example, a cleaning liquid distribution system is used to distribute cleaning liquid to the main brush roller 11 and the side brushes 12. A typical cleaning fluid dispensing system includes a fluid pump 13, a side fluid supply path 14, and a main fluid supply path 15. The inlet 131 of the liquid pump 13 is communicated with the solution tank 23 through a pipeline 16, the outlet 132 of the liquid pump 13 is communicated with the path inlet of the main liquid supply path 15, the main liquid supply path 15 is allocated to supply cleaning liquid to the main brush roller 11, and the path outlet of the main liquid supply path 15 is composed of a plurality of nozzles 17 facing the main brush roller 11. The path inlet of the side liquid supply path 14 is connected to the main liquid supply path 15, and the path outlet of the side liquid supply path 14 is formed by a nozzle 18 facing the side brush 12, and the side liquid supply path 14 is adapted to supply the cleaning liquid to the side brush 12. In other embodiments, the path inlet of the side feed path may also be connected separately to the solution tank, i.e. constitute a separate one-way fluid path in parallel with the main feed path.

Since the side liquid supply path 14 is dedicated to supplying the cleaning liquid to the side brush 12 and the side brush 12 is mainly used to clean the wall surface 600, in order to save the amount of the cleaning liquid used, a control device for managing the path is designed in the side liquid supply path 14 for controlling the opening or closing of the side liquid supply path 14, that is, by which the side liquid supply path 14 can be switched between opening and closing. The control device is configured to open the side liquid supply path 41 when the first side 103 of the base housing 10 moves to the wall surface 600 perpendicular to the floor 500 and to close the side liquid supply path 14 when leaving the wall surface 600. The solution can be realized as the side brush 3 is supplied with liquid as required.

One possible embodiment of the control means is seen in fig. 4, the control means 3 being constituted in part by a fluid controller 31. The fluid controller 31 is provided on the side liquid supply path 14 and is configured to open or close the side liquid supply path 14 by controlling the flow of the cleaning liquid in the side liquid supply path 14. The fluid controller 31 may be either mechanical or electronically controlled, typically as a mechanical valve, solenoid valve or liquid electronic pump. The control device 42 also includes a movable member 32, the movable member 32 being configured to be actuated by the wall surface 600 to move from a first position to a second position upon touching the wall surface 600 and to reset upon exiting the wall surface 600, the fluid controller 31 being coupled to the movable member 32 to effect opening or closing of the side supply path 14 in response to movement of the movable member 32. The movable member 32 may include an outer end 321 configured to be capable of contacting the wall 600 and an inner end 322. The outer end 321 of the movable member 32 is exposed outside the first side 103 of the base housing 1; when the movable member 32 is in the first position, the outer end 321 of the movable member 32 projects laterally beyond the side brush 12, i.e. the outer end 321 projects laterally relative to the first side 103 of the base housing 1 and more laterally than the side brush 12, such that the outer end 321 contacts the wall surface 600 earlier than the side brush 12 when the first side 103 is adjacent to the wall surface 600; when the movable member 32 is in the second position, the outer end 321 of the movable member 32 is laterally flush with the side brush 12. In this example, the outer end 321 of the movable member 32 includes a rotatable roller 33, and the roller 33 can reduce the influence on the movement of the cleaning base 1 when the outer end 321 of the movable member 32 contacts the wall surface 600. The mutual movement of the movable member 32 between the first and second positions can trigger the opening or closing of the fluid controller 31, thereby effecting the opening or closing of the side feed path 24.

As shown in fig. 5-6, taking the fluid controller 31 as an example of a mechanical valve, when the cleaning base 10 moves to the wall surface 600, the outer end 321 of the movable component 32 is firstly contacted with the wall surface 600, the movable component 32 is triggered to move from the first position as shown in fig. 5 to the second position as shown in fig. 6 under the extrusion action of the wall surface 600, the valve core 311 in the fluid controller 31 is extruded by the inner end 322 of the movable component 32 to move towards the inner side, the valve core 311 is opened, the flow channel communicating the liquid inlet 312 and the liquid outlet 313 in the fluid controller 31 is communicated, and then the side liquid supply path 14 is opened, so that the cleaning liquid is continuously conveyed to the side brush 12 under the action of the liquid pump 13. When the cleaning base 10 is far away from the wall surface 600, the movable part 32 is separated from the wall surface 600, the squeezing action of the wall surface 600 is lost, the movable part 32 automatically resets from the second position to the first position under the action of the spring 314, and the fluid controller 31 can close the side fluid supply path 14 in response to the resetting action, so that the fluid supply to the side brush 12 is stopped.

As with the control device 30 shown in fig. 7-9, the control device 30 includes a fluid controller 310 and a movable member 320. The fluid controller 310 is comprised of a solenoid valve that itself carries an electronic switch 3101 that can trigger its opening and closing. Movement of the moving member 320 between the first position and the second position may trigger the electronic switch 3101 of the solenoid valve to open and close.

As shown in fig. 8-9, when the cleaning base 10 is moved to the wall surface 600, the outer end 3201 of the movable member 320 is first contacted with the wall surface 600, the movable member 320 is triggered to move from the first position as shown in fig. 8 to the second position as shown in fig. 9 by the pressing action of the wall surface 600, the electronic switch 3101 is touched by the inner end 3202 of the movable member 320, the electronic switch 3101 is turned on, the fluid controller 310 is turned on, and the side liquid supply path 14 is turned on; so that cleaning liquid is continuously supplied to the side brush 12 by the liquid pump 13. When the cleaning base 10 is far away from the wall surface 600, the movable component 320 is separated from the wall surface 600, the squeezing action of the wall surface 600 is lost, the movable component 320 automatically resets from the second position to the first position under the action of the spring 3140, and the fluid controller 310 can close the side fluid supply path 14 in response to the resetting action, so that the fluid supply to the side brush 12 is stopped.

Referring to another embodiment of the control device shown in fig. 10, the control device 4 includes a fluid controller 41 and a wall surface detection assembly 42, the fluid controller 41 being configured to open the side supply path 14 based on the signal and close the side supply path 14 when the signal is lost, the wall surface detection assembly 42 being configured to be triggered to continue to generate a signal when touching or approaching the wall surface 600. The wall surface detection assembly 42 may be at least one set of distance sensors, which may be infrared emitting and/or ultrasonic emitting and receiving devices, etc., capable of detecting that the first side 103 is close to or in contact with the wall surface 600, or at least one set of pressure sensors, the wall surface detection assembly 42 preferably being mounted at the first side 103. The wall surface detection assembly 42 of this example is triggered to signal when the cleaning base 10 touches or approaches the wall surface 600, which can trigger the fluid controller 41 to open or close, thereby opening or closing the side fluid supply path 14. The fluid controller 41 is in this case electronically controlled, i.e. the fluid controller 41 is provided with an electrically controlled switch; the electrically controlled switch of the fluid controller 41 is coupled to the wall surface detection assembly 42 such that the fluid controller 41 is capable of controlling the fluid controller 41 to open in response to a signal sent by the wall surface detection assembly 42 to effect the opening of the side fluid supply path 14, and to open the fluid controller 7 to close in response to a signal sent by the wall surface detection assembly 42 to effect the closing of the side fluid supply path 14.

As shown in another embodiment of the side supply path in FIG. 11, in this example, the side supply path 140 includes a length of flexible tubing 141 that is deformable, the flexible tubing 141 having a collapsed state blocking fluid flow and an open state for fluid flow. The control device 5 comprises a movable part 51 and a clamping mechanism 52 positioned at the flexible hose 141, the clamping mechanism 52 having a clamping position clamping the flexible hose 141 and restraining the flexible hose 141 in a collapsed state and an open position releasing the flexible hose 141. The movable member 51 is configured to move from a first position to a second position in response to contact with the wall 600 and to reset in response to disengagement from the wall 600, and the clamping mechanism 52 is coupled to the movable member 51 and is switchable between a clamped position and an undamped position in response to movement of the movable member 51 between the first and second positions.

As shown in fig. 12-13, the movable member 51 includes an outer end 511 configured to be capable of touching the wall 600; the outer end 511 of this example is defined by a roller 54 which is rotatable about its own axis. The movable member 51 is configured to move from a first position to a second position in response to contact with the wall 600 and to reset in response to disengagement from the wall 600. When the movable member 51 is in the first position, a portion of the roller 54 protrudes laterally beyond the side brush 12 with respect to the first side 103 of the base housing 1; the movable member 51 is in the second position with the roller 54 laterally flush with the side brush 12.

The clamping mechanism 52 includes a first clamping member 521 and a second clamping member 522 that is capable of opening and closing movement relative to the first clamping member 521. The flexible hose 141 is positioned between the first clamping member 521 and the second clamping member 522. The first clamping member 521 is fixedly provided with the base housing 10, the second clamping member 522 is formed as an integral member with the movable member 51 and both are supported on the base housing 10 by the spring 53, and the second clamping member 522 is capable of opening and closing movement with respect to the first clamping member 521 with movement of the movable member 51 between the first position and the second position. When the clamping mechanism 52 is in the clamped position, the first 521 and second 522 clamping members approach each other and clamp the flexible hose 141 therebetween, and the flexible hose 141 will be restrained in a collapsed state; when the clamping mechanism 52 is in the open position, the first and

second clamping members

521, 522 are moved away from each other, the flexible tube 141 is released, and the flexible tube 141 is moved from the collapsed state to the expanded state. In other embodiments, the second clamping member and the movable member may be separately provided, and a transmission relationship is formed between the second clamping member and the movable member, that is, the second clamping member may be movable relative to the first clamping member to perform an opening and closing movement when the movable member moves between the first position and the second position.

Referring to fig. 12, the cleaning base 1 is far from the wall surface, the movable member 51 is in the first position, and the partial roller 54 of the movable member 51 projects laterally beyond the first side 103 of the base housing 1 and projects laterally beyond the side brush 12, i.e., the partial roller 54 projects laterally more than the side brush 12, such that when the first side 103 is moved to a position close to the wall surface 600, the partial roller 54 touches the wall surface 600 at a first time; the clamp mechanism 52 is in the clamped position, the flexible hose 141 is clamped and restrained in the collapsed state by the first clamp member 521 and the second clamp member 522, and the side liquid supply path 14 is closed. Referring to fig. 13, the cleaning base 1 is moved to the wall surface 600, the first side 103 is close to the wall surface 600, the roller 54 is moved to a position laterally flush with the side brush 12 by the touch of the wall surface 600, the movable member 51 is moved to the second position, the second clamping member 522 is opened with respect to the first clamping member 521, the flexible hose 141 is released and brought into an opened state, and the side liquid supply path 14 is opened. Accordingly, when the movable member 51 moves toward the inside direction, the gripping mechanism 52 can be opened in response to the movement, thereby releasing the flexible hose 141, and the flexible hose 141 enters the open state; when the movable member 51 leaves the wall surface 600, the clamping mechanism 52 is moved into the clamping position by the spring 54, the flexible tube 141 is clamped, the flexible tube 141 is moved into the flattened state, and the second clamping member 522 of the clamping mechanism 52 further moves the movable member 51 to return. This embodiment is capable of achieving opening and closing of the control-side liquid supply path by controlling self-deformation of the flexible hose without using the fluid controller, as opposed to the above-described respective embodiments.
