Note that the detailed descriptions of the specific embodiments are to be construed as interpretations and explanations for the purpose of the application and should not be construed as an undue limitation of the application.

Embodiments of the present application provide a cleaning device, which can be used for cleaning media to clean the ground, glasses, etc., and when the cleaning device operates, the cleaning device is placed on the surface of the cleaning media. do it.

The cleaning device may be a cleaning robot, a window cleaning robot, or similar types of devices, and is not limited herein. In the embodiments of the present application, the cleaning device is a cleaning robot as an example.

Referring to FIG. 1, the cleaning equipment comprises a water pumping device 30, a cleaning area 10a and an action performing mechanism 20, wherein the water pumping device 30 comprises a housing portion 31 and a transition connection mechanism 33, wherein the housing portion 31 contains a A space 310 and a drain port 31b communicating with the accommodation space 310 are formed, the drain port 31b communicates with the washing area 10a, for example, via a drain pipe 37, and the transition connection mechanism 33 is connected to the operation execution mechanism 20. Driven and connected, the transition connection mechanism 33 can pump up the water in the housing space 310 to the cleaning area 10a by driving the operation execution mechanism 20 .

The cleaning equipment of the embodiment of the present application uses the off-the-shelf operation execution mechanism 20 as a power source to drive the water pumping operation via the transfer connection mechanism 33, and the amount of water supply required for the cleaning area 10a needs to be controlled by a control circuit. is determined by the operation of the operation execution mechanism 20 and the volume of water used for storage water in the accommodation space 310, compared with the method of replenishing water with a water pump in the prior art, in the embodiment of the present application The structure of the water pumping device 30 is more reliable and practical, and the production and manufacturing costs are lower, which is very beneficial for popularization and use.

It should be noted that the action execution mechanism 20 mentioned above refers to an external execution mechanism, such as a running wheel 20' or a rolling brush, for realizing the cleaning function of the cleaning equipment. The running wheels 20' perform the running function of the cleaning appliance, and in order to achieve a continuous cleaning operation, the cleaning appliance requires running of the running wheels 20', and the rolling brushes carry the cleaning media of the cleaning appliance. Perform the scratching function.

The cleaning area 10a refers to a portion that contacts the cleaning member 40, and the cleaning member 40 can be a rag, a sponge, etc. For example, referring to FIG. The cleaning member 40 is attached to the bottom of the bracket 12 before the cleaning equipment operates normally, and the water in the accommodation space 310 is pumped into the cleaning area 10a, and the water in the cleaning area 10a is discharged by the cleaning member 40. After being absorbed, the cleaning member 40 wipes and cleans the cleaning medium during movement of the cleaning device.

The transition connection mechanism 33 can pump water in the accommodation space 310 to the washing area 10a with other structures, and can also pump water in the accommodation space 310 to the washing area 10a without the need for other structures. For example, the transition connection mechanism 33 is driven by the operation execution mechanism 20 to pump air or other gas in one direction into the accommodation space 310, and the water in the accommodation space 310 is pushed into the cleaning area 10a by the action of air pressure. Note the pumping.

In the present embodiment, the transfer connection mechanism 33 pumps the water in the accommodation space 310 to the washing area 10a by other structures, specifically, the water pumping device 30 includes a water pumping unit 32, and the water pumping unit 32 is connected to the storage space. 310, the pumping portion 32 and the containing portion 31 surround to form a water cavity 311, the pumping portion 32 being able to pump the water in the water cavity 311 to the washing area 10a, i.e. the transition The connection mechanism 33 pumps up the water in the housing space 310 to the cleaning area 10a by the pumping unit 32 . The present embodiment transmits power to the water pumping portion 32 via the transition connection mechanism 33, and further drives the water pumping portion 32 to perform a draining operation, thus allowing the water in the water cavity 311 to directly apply greater pressure to facilitate the pumping of the water in the receiving cavity 311 to the cleaning area 10a.

As long as a specific volume of water can be stored, the specific structure of the storage section 31 is not limited, and is not limited here. In some embodiments, the cleaning device includes a water tank 11, in which a certain volume of water or detergent is pre-stored, and for convenience of explanation, the embodiments of the present application take water as an example. The accommodation part 31 can be at least part of the structure of the water tank 11 , for example, a part of the space is separated from the space inside the water tank 11 to form an accommodation space for the accommodation part 31 , and Pre-stored water enters the water cavity 311 through a through hole of a specific diameter. Further, for example, the water tank 11 itself is the housing portion 31, and the space inside the water tank 11 is the housing space 311 described above.

Further, for example, referring to FIG. 1, in the embodiment of the present application, the housing part 31 is disposed outside the water tank 11, the housing part 31 is formed with a water inlet 31a communicating with the water cavity 311, and the water inlet 31a is It communicates with the water tank 11 . It should be understood that the accommodation part 31 may be fastened connected to the water tank 11 or may be spaced apart from the water tank 11 and is not limited here. In the embodiment of the present application, by arranging the housing part 31 outside the water tank 11, it is possible to increase the volume of the water tank 11 in the limited space of the cleaning equipment, and to improve the water storage capacity. , on the other hand, the relative positions between the water tank 11, the washing area 10a and the container 31 can be arranged flexibly, as long as there is communication between the three via corresponding pipelines, thus , the design of the structure of the washing equipment can be made more flexible, and the arrangement of the structure of the washing equipment can be more reasonable and compact.

In the present embodiment, the action performing mechanism 20 is the running wheel 20', the transition connecting mechanism 33 is connected to the running wheel 20', and the rotation process of the running wheel 20' is related to the moving distance of the cleaning equipment, thus: The range of motion of the water pump 32 is related to the distance traveled by the cleaning equipment. Specifically, when the cleaning equipment is not moving, the running wheels 20' are stationary, the transition connection 33 is stationary, and the water pump 32 is stationary, in which case the cleaning member 40 does not perform a wiping cleaning action. , the water pumping device 30 also does not discharge water into the washing area 10a. When the cleaning equipment moves a short distance, the rotation range of the running wheel 20' is relatively narrow, and the movement stroke of the water pumping unit 32 is relatively small. Although relatively small, when the cleaning equipment moves a short distance, the amount of water supply required for the cleaning member 40 is also relatively small, so the amount of water discharged by the water pumping device 30 to the cleaning member 40 and the amount of water supply required for the cleaning member 40 are relatively small. is a better match. Similarly, when the moving distance of the cleaning equipment is relatively large, the amount of water pumped by the water pumping device 30 pumped into the cleaning area 10a is relatively large, and the amount of water supply required for the cleaning member 40 is also relatively large.

In one embodiment, the transition connection mechanism 33 is connected to one axial side of the running wheel 20'. In this way, the connection between the transition connection mechanism 33 and the running wheel 20' is facilitated. Moreover, the transition connection 33 is connected axially inside the running wheel 20', in this way the transition connection 33 is not exposed to the outside of the cleaning appliance and during operation of the cleaning appliance the transition connection 33 is not exposed to the outside. Conveniently, 33 does not interfere with other external objects, and the structural arrangement of the water pumping device 30 is more rational and compact.

The storage part 31 and the pumping part 32 have various structural forms. For example, in one embodiment housing 31 is cylindrical and correspondingly pumping section 32 is piston 32', in another embodiment housing 31 is spiral and pumping section 32 is the rotor.
The relative positions of the water tank 11, the action execution mechanism 20, the transition connection mechanism 33 and the cleaning area 10a can be appropriately changed as needed.
Specific embodiments of the present application will now be described with reference to the drawings.

First Embodiment Referring to FIGS. 1 and 2, in this embodiment, the housing portion 31 is arranged outside the water tank 11 . The housing portion 31 is cylindrical, one end of the housing portion 31 is a closed end and the other end is an open end, the pumping portion 32 is a piston 32 ′, and the piston 32 ′ is linear within the housing portion 31 . , the piston 32' alternately introduces the water in the water tank 11 into the water cavity 311 and pumps the water in the water cavity 311 to the washing area 10a. That is, at the same time, only one of the operation of introducing the water in the water tank 11 into the water cavity 311 and the operation of pumping up the water in the water cavity 311 to the cleaning area 10a can be selected. , the transition connection mechanism 33 drives the piston 32' to slide in the left first direction shown in FIG. , the water in the water tank 11 is sucked into the water cavity 311 by the action of the negative pressure, and in the process, the water channel between the outlet 31b and the washing area 10a is blocked. When the transition connection mechanism 33 drives the piston 32' to slide in a second direction to the right shown in FIG. water to form a certain water pressure, which can pump water into the washing area 10a, in the process, the waterway between the water inlet 31a and the water tank 11 is blocked.

In order to facilitate the opening and closing control of the channel between the water inlet 31a and the water tank 11 and the opening and closing control of the channel between the outlet 31b and the washing area 10a, a valve body is arranged in the corresponding channel, Can be turned on or off at the appropriate time. The type of structure of the valve body is not limited, and may be an electric control valve or a hydraulic control valve.

In this embodiment, the pumping device 30 comprises a first one-way valve 34, which belongs to one of the hydraulic control valves, i.e. to turn on or off the control without the need for electromagnetic control. be able to. A first one-way valve 34 is arranged in the water channel between the water inlet 31 a and the water tank 11 . The first one-way valve 34 can make water flow in one direction from the water tank 11 side to the water inlet 31a side, that is, the liquid inlet end of the first one-way valve 34 is connected to the water tank 11 and the water inlet 31a. Communicating, it should be understood that the liquid outlet end of the first one-way valve 34 communicates with the water inlet 31a. The structure of the first one-way valve 34 is simple, and it can be automatically turned on and off by water pressure without the need for electrical control. For example, when the negative pressure in the water cavity 311 is greater than the opening pressure of the first one-way valve 34 , the first one-way valve 34 is turned on and the water in the water tank 11 is released under the negative pressure of the water cavity 311 . Under action, when entering the water cavity 311 via the first one-way valve 34 and the water in the water cavity 311 forms pressure, the water pressure acts in the opposite direction on the first one-way valve 34, The first one-way valve 34 is turned off, and the water pressure in the water tank 11 is insufficient to turn on the first one-way valve 34, so the first one-way valve 34 is stably and reliably will automatically shut off.

The water pumping device 30 comprises a second one-way valve 35, which is arranged in the waterway between the drain 31b and the washing area 10a. The working principle and operation process of the second one-way valve 35 are similar to the first one-way valve 34 and will not be repeated here.

Taking the drain port 31b as an example, when the drain port 31b is arranged on the side wall of the housing portion 31, that is, when it is arranged at the non-closed end position, when the piston 32' moves toward the closed end side, the piston 32 ' moves around the piston 32' and blocks the drain port 31b, the water in the water cavity 311 cannot be drained, and the piston 32' moves toward the closed end by driving the transition connection mechanism 33. If this continues, the water pressure in the water cavity 311 will be restrained, and if the pressure continues to rise, it can damage the piston 32', the housing 31 or the valve body described above. Therefore, when designing the product, the movement range of the piston 32' cannot cover the position of the drain port 31b, but in this case, under the same conditions, the size of the movement direction of the housing 31 along the piston 32' is increased. be.
