DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] The present invention provides an inclined abutting surface at the end of the water pumping pipe, and the surface protrudes from the outside of the first side wall of the housing. The charging stand provided by the embodiment of the present invention has one end of the water pumping pipe provided with the inclined abutting surface protruding from the housing. When the water pumping pipe of the charging stand is docked with the water inlet and outlet of the sweeper, the end surface of the water pumping pipe pushes open the valve of the sweeper, so that the water pumping pipe is connected with the water inlet and outlet of the sweeper, and the inclined abutting surface of the water pumping pipe abuts against the inner wall of the valve port of the sweeper, so that the water pumping pipe and the valve port are sealed, so that the water pumping pipe of the charging stand is easy to dock with the water inlet and outlet of the sweeper, thereby realizing automatic water addition or discharge.

[0045] Embodiment 1

[0046] like Figure 1-Figure 8As shown, an embodiment of the present invention provides a charging stand 100, including a housing 11, a first water tank 12 and a pumping device arranged in the housing 11, wherein the pumping device is used to add water to or drain water from the sweeper 200, including:

[0047] a water pump 13 connected to the first water tank 12;

[0048] A bendable tube 14 connected to the water pump 13;

[0049] A positioning member 15 installed in the housing 11;

[0050] A water extraction pipe 16 is installed on the positioning member 15 , one end of which is connected to the bendable pipe 14 , and the other end of which is provided with an inclined abutting surface 161 and protrudes outward from the first side wall 111 of the housing 11 .

[0051] The embodiment of the present invention is suitable for both adding water to the sweeping machine 200 and draining water from the sweeping machine 200. When draining water, the water can be directly discharged to the outside of the charging stand 100 without using a water tank.

[0052] The first water tank 12 is connected to the water pump 13 through a water pipe. When adding water to the sweeping machine 200, the water pump 13 pumps the water in the first water tank 12 into the second water tank of the sweeping machine 200 through the water pipe. When draining the water from the sweeping machine 200, the water pump 13 pumps the water in the second water tank of the sweeping machine 200 through the water pumping pipe 16 and flows it into the first water tank 12 or outside the charging stand 100 through the water pipe.

[0053] The outer diameter of the end of the inclined abutting surface 161 is smaller than the minimum inner diameter of the valve port 222 , and the outer diameter of the water suction pipe 16 is larger than the minimum inner diameter of the valve port 222 . The inclined abutting surface 161 of the water suction pipe 16 can abut against the inner wall of the valve port 222 of the sweeper.

[0054] The charging stand 100 provided in the embodiment of the present invention has one end of the water suction pipe 16 provided with an inclined abutment surface 161 protruding from the housing 11. When the water suction pipe 16 of the charging stand is docked with the water inlet and outlet 21 of the sweeping machine, the end face of the water suction pipe 16 pushes open the valve 23 of the sweeping machine, so that the water suction pipe 16 is connected with the water inlet and outlet 21 of the sweeping machine, and the inclined abutment surface 161 of the water suction pipe 16 abuts against the inner wall of the valve port 222 of the sweeping machine, so that the water suction pipe 16 and the valve port 222 are sealed, thereby making it easy for the water suction pipe 16 of the charging stand to dock with the water inlet and outlet 21 of the sweeping machine, thereby realizing automatic water addition or discharge.

[0055] Embodiment 2

[0056] like Figure 3-Figure 8As shown, in an optional embodiment of the present invention, based on the first embodiment, the water extraction pipe 16 is movably mounted on the positioning member 15, and a protrusion 162 is provided on the water extraction pipe 16, and the protrusion 162 is located on the inner side of the first side wall 111 of the housing 11;

[0057] The pumping device also includes a first elastic body 17, one end of the first elastic body 17 abuts against the positioning member 15, and the other end abuts against the protrusion 162, and the protrusion 162 is located between the first side wall 111 of the casing and the first elastic body 17, that is, the other end of the first elastic body 17 abuts against the side of the protrusion 162 away from the first side wall 111 of the casing 11.

[0058] Among them, the first elastic body 17 can be a spring, which is sleeved on the water extraction pipe 16. When there is no external force, under the elastic force of the first elastic body 17, the protrusion 162 abuts against the first side wall 111 of the casing 11. The bendable tube 14 can be a hose or a bendable tube wrapped in metal. The water pump 13 pumps water from the charging seat 100 to the sweeping machine 200 to add water, and pumps water from the sweeping machine 200 to the charging seat 100 or the outside of the sweeping machine 200 to drain water. One end of the water extraction pipe 16 is supported by the positioning member 15, and the other end passes through the first side wall 111 of the casing 11 and protrudes outside the first side wall 111 of the casing 11.

[0059] In the present invention, the protrusion 162 moves between the first elastomer 17 and the first side wall 111 of the casing 11. The protrusion 162 can squeeze the first elastomer 17 under the action of external force. The longer the compression distance of the first elastomer 17 is, the greater the pre-tightening force provided by the first elastomer 17 is, and the greater the squeezing force between the inclined abutting surface 161 of the water suction pipe and the inner wall of the valve port 222 is after entering the valve port 222. The water suction pipe 16 and the valve port 222 of the sweeper are more tightly connected, and the connection is less likely to leak.

[0060] One end of the water pumping pipe 16 provided with the inclined abutment surface 161 is also provided with a second water flow notch 163, and water can go out or enter the water pumping pipe 16 through the second water flow notch 163. One end of the water pumping pipe 16 provided with the inclined abutment surface 161 protrudes from the housing 11, and can also provide positioning for the sweeping machine 200 when the water pumping pipe 16 of the charging seat is docked with the water inlet and outlet 21 of the sweeping machine, so that after the water pumping pipe 16 is pre-docking with the valve port 222, the sweeping machine 200 is then close to the charging seat 100, so that the water pumping pipe 16 and the valve port 222 are docked. The first elastic body 17 is provided so that the end position of the water pumping pipe 16 can be automatically adjusted, so that when the water pumping pipe 16 of the charging seat is docked with the water inlet and outlet 21 of the sweeping machine, the positional relationship between the sweeping machine 200 and the charging seat 100 can be adjusted, thereby ensuring that the charging sheet 19 of the sweeping machine 200 is in contact with the charging sheet 19 of the charging seat 100.

[0061] In the charging stand 100 provided in the embodiment of the present invention, one end of the movable water pumping pipe 16 provided with an inclined abutting surface 161 protrudes from the housing 11, and a protruding portion 162 is provided on the water pumping pipe 16, and a first elastic body 17 is provided to act on the protruding portion 162, so that the water pumping pipe 16 further protrudes from the housing 11 under the elastic force of the first elastic body 17. When the water pumping pipe 16 of the charging stand is docked with the water inlet and outlet 21 of the sweeping machine, the water pumping pipe 16 pushes open the valve 23 of the sweeping machine 200, so that the water pumping pipe 16 is connected with the water inlet and outlet 21 of the sweeping machine, and the inclined abutting surface 161 of the water pumping pipe abuts against the inner wall of the valve port 222 of the sweeping machine, so that the water pumping pipe 16 and the valve port 222 are sealed, and the valve 23 and the valve port 222 are closed. 2, the first elastic body 17 can be compressed by the water pumping pipe 16 under the reaction force of the inner wall of the housing 11, so that the position of the water pumping pipe 16 protruding from the housing 11 can be adjusted, which can ensure that the charging piece 19 of the sweeping machine 200 contacts the charging piece 19 of the charging stand 100 during the docking process between the water pumping pipe 16 of the charging stand and the water inlet and outlet 21 of the sweeping machine; at the same time, the first elastic body 17 can also provide a pre-tightening force for the inclined abutting surface 161 of the water pumping pipe to abut against the inner wall of the valve port 222 of the sweeping machine and push the valve 23, so that the sealing between the water pumping pipe 16 and the inner wall of the valve port 222 of the sweeping machine is better, and the valve 23 is kept open, so that the water pumping pipe 16 of the charging stand is easy to dock with the water inlet and outlet 21 of the sweeping machine, thereby realizing automatic water addition or discharge. The first elastic body 17 is provided to allow the part of the water extraction pipe 16 protruding from the housing 11 to be movable, and also to play a buffering role when the water extraction pipe 16 collides with the water extraction pipe during sweeping, thereby preventing the water extraction pipe 16 from being damaged by foreign objects such as the sweeper.

[0062] Embodiment 3

[0063] like Figure 4 , Figure 6 As shown, in an optional embodiment of the present invention, on the basis of the second embodiment, the positioning member 15 of this embodiment is provided with a limiting portion 151, and the protruding portion 162 is located between the limiting portion 151 and the first side wall 111 of the housing 11. The pumping device also includes a touch switch 18 for controlling the switch of the water pump 13, and a pressing portion 164 for pressing the touch switch 18 is also provided on the outside of the water pump 16. When the protruding portion 162 abuts against the limiting portion 151, the pressing portion 164 presses the touch switch 18. The touch switch 18 is one of the dual start switches of the water pump 13. The pressing portion 164 can also be provided on the protruding portion 162.

[0064] Among them, the protrusion 162 of the water suction pipe 16 can move in the gap between the limiting portion 151 of the positioning member 15 and the first side wall 111 of the casing 11, that is, the movable distance of the water suction pipe 16 is the length of the gap between the limiting portion 151 of the positioning member 15 and the first side wall 111 of the casing 11.

[0065] The over-compression of the first elastic body 17 will cause elastic fatigue of the first elastic body 17, thereby reducing the service life of the first elastic body 17. The limiting portion 151 is provided to prevent over-extrusion of the first elastic body 17 and the touch switch 18. When the protrusion 162 abuts against the limiting portion 151, the pressing portion 164 just presses the touch switch 18. When the water inlet and outlet 21 of the sweeper is in contact with the water pumping pipe 16, when the touch switch 18 is pressed, it indicates that the water pumping pipe 16 and the docking object have been tightly docked.

[0066] Specifically, Figure 6 As shown, the positioning member 15 is further provided with a first cavity 152, the first end of the first cavity 152 is provided with an opening, and the opening faces the first side wall 111 of the housing 11, and the second end opposite to the first end is provided with a first through hole 153 for the water pumping pipe 16 to pass through, and the side of the first cavity 152 is provided with a position avoidance groove 154, and the pressing portion 164 can pass through the position avoidance groove 154 and move with the water pumping pipe 16, and the first elastic body 17 is arranged in the first cavity 152 and abuts against the second end of the first cavity 152. One end of the water pumping pipe 16 passes through the first through hole 153, and the other end passes through the first side wall 111 of the housing 11 and protrudes outside the first side wall 111 of the housing 11. The limiting portion 151 can be arranged in the first cavity 152. Among them, the first elastic body 17 can enter the first cavity 152 from the opening, and the protruding portion 162 of the water pumping pipe 16 can also enter the first cavity 152 from the opening. The avoidance groove 154 extends along the moving direction of the water pumping pipe 16 , and the pressing portion 164 can pass through the avoidance groove 154 and move along with the water pumping pipe 16 .

[0067] Furthermore, if Figure 2 As shown, the charging stand 100 also includes a charging device disposed in the housing 11, and the charging device includes a charging sheet 19 exposed to the housing 11. When the charging sheet of the sweeping machine 200 contacts the charging sheet 19 of the charging stand 100, it indicates that the sweeping machine 200 has reached a predetermined position, and the sweeping machine 200 can be charged at this time, and current flows through the charging sheet of the sweeping machine 200.

[0068] However, if Fig. 9 , Fig.10 As shown, the side of the sweeper 200 presses against the water pumping pipe 16, and the touch switch 18 is also pressed. At this time, the water inlet and outlet 21 of the sweeper and the water pumping pipe 16 are not yet connected. In addition, since the charging seat 100 and the charging sheet 19 of the sweeper 200 are both elastic springs, in some cases, the charging seat 100 and the charging sheet 19 of the sweeper 200 may have contacted and started charging, but the sweeper 200 has not returned to the predetermined position. At this time, the water inlet and outlet 21 of the sweeper and the water pumping pipe 16 are not yet connected.

[0069] To solve the above problems, further, in an optional embodiment of the present invention, the pumping device also includes a controller (not shown in the figure) for controlling the switch of the water pump 13. After the controller receives the signal that the charging piece 19 has current passing through and the signal that the touch switch 18 is pressed, the water pump 13 is turned on. Specifically, when the sweeping machine 200 needs to add water or drain water, a signal for adding water or draining water is first sent to the controller. The sweeping machine 200 then slowly approaches the charging seat 100 and gradually reaches the designated position, and docks with the water pumping pipe 16. When the controller receives the signal that the charging piece 19 has current passing through and the signal that the touch switch 18 is pressed, it means that the sweeping machine 200 has reached the predetermined position, and the water inlet and outlet 21 of the sweeping machine and the water pumping pipe 16 are tightly docked. At this time, the water pump 13 can be turned on to add water or drain water for the sweeping machine 200. By detecting double signals, that is, double switches controlling the operation of the water pump 13, it can be ensured that the water pump 13 is turned on only after the water inlet and outlet 21 of the sweeper and the water suction pipe 16 are tightly connected, thereby preventing the water pump 13 from being started by mistake.

[0070] Embodiment 4

[0071] like Figure 1 As shown, in an optional embodiment of the present invention, the first water tank 12 is detachably installed in the housing 11. The first water tank 12 is detachable, which is conducive to cleaning the first water tank 12 and replacing the water tank when the first water tank 12 is damaged.

[0072] Embodiment 5

[0073] like Figure 2 As shown, in an optional embodiment of the present invention, the pumping device further includes a filter 121 disposed between the first water tank 12 and the water pump 13. The filter 121 can be disposed at the water outlet of the first water tank 12, and the filter 121 is used to filter impurities in the water to prevent the impurities from entering the water pump 13 and affecting the service life of the water pump 13.

[0074] Embodiment 6

[0075] like Figure 11-13 As shown, an embodiment of the present invention further provides a sweeping machine 200, comprising a main unit and a second water tank (not shown in the figure) disposed in the main unit, wherein a valve assembly adapted to a water pumping pipe 16 of a charging stand is disposed at a water inlet and outlet 21 of the second water tank, and the valve assembly further comprises:

[0076] A valve sleeve 22 is arranged outside the water inlet and outlet 21 of the second water tank, and the valve sleeve 22 is provided with a second cavity 221. The first end of the second cavity 221 is open, and the second end opposite to the first end is provided with a valve port 222 for the end of the water pumping pipe 16 of the charging seat to pass through, and the inner wall of the valve port 222 can be sealed with the inclined abutment surface 161 of the water pumping pipe;

[0077] a valve 23 disposed in the second cavity 221 to block the valve port 222;

[0078] A second elastic body 24 provides a pre-tightening force for the valve 23 to block the valve port 222 .

[0079] The valve sleeve 22 is sealedly connected to the second water tank, and the valve sleeve 22 surrounds the water inlet and outlet 21 of the second water tank, so that the second cavity 221 is connected to the water inlet and outlet 21, and then the valve 23 is used to block the valve port 222, so that the second water tank and the second cavity 221 are sealed. Only when the valve 23 is opened under the action of external force can water be added or drained to the second water tank through the second cavity 221. When there is no external force, the valve 23 blocks the valve port 222 under the elastic force of the second elastic body 24.

[0080] Specifically, Fig.14 As shown, the valve 23 includes a support portion 231 with one end extending into the water inlet and outlet 21 of the second water tank and a blocking portion 232 arranged at the other end of the support portion 231. A water flow groove 233 is arranged at the periphery of the support portion 231, and a first water flow gap 234 is arranged at the periphery of the blocking portion 232. When the water pumping pipe 16 pushes the valve 23 open, the water in the water pumping pipe 16 can flow into the second water tank through the second water flow gap 163, the second cavity 221, the first water flow gap 234 and the water flow groove 233.

[0081] The second elastic body 24 is a spring, which is sleeved on the supporting portion 231 and abuts against the blocking portion 232 to provide elastic force for the valve 23 to block the valve port 222 .

[0082] The sweeping machine 200 provided in the embodiment of the present invention is provided with a valve 23 and a second elastomer 24. When there is no external force, the valve 23 blocks the valve port 222 under the action of the second elastomer 24. When the water suction pipe 16 of the charging seat is connected with the water inlet and outlet 21 of the sweeping machine, since the valve 23 blocks the valve port 222 under the action of the second elastomer 24, when the force of the first elastomer 17 is greater than the force of the second elastomer 24, under the action of the water suction pipe 16 of the charging seat and the first elastomer 17, the valve 23 can be easily pushed open, so that the water suction pipe 16 is connected with the water inlet and outlet 21 of the sweeping machine, and the inclined abutting surface 161 of the water suction pipe abuts against the inner wall of the valve port 222 of the sweeping machine, so that the water suction pipe 16 and the valve port 222 are sealed, so that the water suction pipe 16 of the charging seat is easy to connect with the water inlet and outlet 21 of the sweeping machine, thereby realizing automatic water addition or discharge.

[0083] Furthermore, if Fig.13 As shown, a guide portion 223 is provided at one end of the valve port 222 away from the second cavity 221.

When the valve assembly is matched with the water suction pipe 16 of the charging station, the inclined abutting surface 161 of the water suction pipe squeezes the valve port 222, so that the sealing between the inclined abutting surface 161 of the water suction pipe and the valve port 222 is better.

[0086] Embodiment 8

[0087] like Figure 7 , Figure 8As shown, an embodiment of the present invention further provides a sweeping machine system, comprising the above-mentioned charging stand 100 and the above-mentioned sweeping machine 200, when the water pumping pipe 16 of the charging stand is matched with the valve assembly of the sweeping machine 200, the inclined abutting surface 161 of the water pumping pipe is sealed against the inner wall of the valve port 222, and the end of the water pumping pipe 16 abuts against the valve 23 and pushes the valve 23 open. Among them, the valve port 222 is circular, the end of the water pumping pipe 16 is conical, and the conical surface forms an inclined abutting surface 161; the elastic force of the first elastic body 17 is greater than the elastic force of the second elastic body 24. The water pumping pipe 16 of the charging stand is matched with the valve assembly of the sweeping machine 200, which means that the water pumping pipe 16 of the charging stand is docked with the valve assembly of the sweeping machine 200, and then the water pumping pipe 16 of the charging stand is docked with the water inlet and outlet 21 of the sweeping machine.

[0088] The charging stand 100 provided in the embodiment of the present invention has a movable water pumping pipe 16 with one end having an inclined abutting surface 161 protruding from the housing 11; the sweeping machine 200 provided in the embodiment of the present invention is provided with a valve 23 and a second elastic body 24. When there is no external force, the valve 23 blocks the valve port 222 under the action of the second elastic body 24; when the water pumping pipe 16 of the charging stand is docked with the water inlet and outlet 21 of the sweeping machine, the water pumping pipe 16 pushes open the valve 23 of the sweeping machine 200, so that the water pumping pipe 16 is connected with the water inlet and outlet 21 of the sweeping machine, and the inclined abutting surface 161 of the water pumping pipe abuts against the inner wall of the valve port 222 of the sweeping machine, so that the water pumping pipe 16 and the valve port 222 are sealed, and the valve 23 and the inner wall of the valve port 222 are sealed. Under the reaction force, the water suction pipe 16 can compress the first elastic body 17, so that the position of the water suction pipe 16 protruding from the casing 11 can be adjusted, which can ensure that during the docking process between the water suction pipe 16 of the charging stand and the water inlet and outlet 21 of the sweeping machine, the charging piece 19 of the sweeping machine 200 is in contact with the charging piece 19 of the charging stand 100; at the same time, the first elastic body 17 can also provide a pre-tightening force for the inclined abutting surface 161 of the water suction pipe to abut against the inner wall of the valve port 222 of the sweeping machine and to push the valve 23, so that the water suction pipe 16 and the inner wall of the valve port 222 of the sweeping machine are better sealed, and the valve 23 is kept open, so that the water suction pipe 16 of the charging stand is easy to dock with the water inlet and outlet 21 of the sweeping machine, thereby realizing automatic water addition or discharge.
