Example 1

Referring to fig. 1 to 8, the present invention provides a cleaning robot, which can perform a predetermined task. The cleaning robot includes a body 100 provided with a tank 110, a liquid container 200, and a liquid feeding assembly 300. The liquid container 200 is movably disposed on the machine body 100, and the liquid container 200 has a reservoir 210 with an open top. The priming assembly 300 is used to transfer the liquid in the reservoir 210 into the reservoir 110. It should be noted that the liquid storage tank 110 may be a box structure, or other structures having an accommodating space.

In a specific application scenario, the cleaning robot is a floor scrubber. It is to be understood that the cleaning robot is not limited to the floor washing machine, but may be a restaurant robot, a car washing robot, etc.

The following description will be given mainly taking the cleaning robot as a floor washing machine as an example. However, as can be seen from the above description, the scope of the embodiments of the present invention is not limited thereto.

When the floor washing machine performs a cleaning task, the cleaning liquid in the tank 110 is used to be delivered to cleaning members (not shown) disposed at the bottom of the machine body 100 to wet the cleaning members. As the cleaning task is performed, the cleaning liquid in the tank 110 is continuously consumed. In addition, since the capacity of the tank 110 inside the body 100 is generally small, the tank 110 needs an external base station 600 to be charged. In this embodiment, the liquid container 200 and the liquid adding assembly 300 are used to perform a liquid adding operation on the liquid storage tank 110, so as to ensure that a predetermined cleaning liquid is stored in the liquid storage tank 110.

The liquid adding operation of the existing liquid storage tank is realized by butt joint of a liquid supplementing joint on a floor washing machine and a liquid injection joint on a base station. When liquid is added, the joint of the liquid supplementing joint and the liquid injection joint has high requirements on sealing performance, so that the path planning precision requirement of the floor washing machine when the floor washing machine returns to a base station is high, and the manufacturing and assembling precision of parts is also high. Sometimes, the floor cleaning machine can also carry out the cleaning operation of the cleaning piece when liquid adding operation is carried out, and the vibration generated by the cleaning piece during cleaning can destroy the sealing property between the liquid supplementing joint and the liquid injection joint, so that the problems of liquid leakage or no liquid adding are caused.

The utility model provides a floor scrubber can effectively avoid the emergence of above-mentioned problem at the execution liquid feeding operation in-process, and detailed reason is as follows.

In the present embodiment, referring to fig. 1 to 3, the liquid container 200 has a first state of being accommodated in the machine body 100 and a second state of at least partially positioning the liquid storage tank 210 of the liquid container 200 outside the machine body 100. Wherein, the sidewall of the body 100 is provided with a receiving groove 120, and the liquid container 200 is movably disposed in the receiving groove 120.

As shown in fig. 1, when the liquid container 200 is in the first state, the liquid container 200 is inserted into the accommodating groove 120, and the sidewall of the liquid container 200 is used as a part of the outer shell of the machine body 100, so that the machine body 100 has no obvious hole or notch in appearance, and has more integrity in appearance and elegant appearance. Further, since the liquid container 200 is accommodated in the body 100 when the floor washing machine is in a standby state, the liquid container 200 is not broken when the floor washing machine is manually moved, compared to other fixed filling structures.

Referring to fig. 2, when the container 200 is in the second state, at least a portion of the reservoir 210 is located outside the opening of the accommodating groove 120. In the second state, the top opening of the reservoir 210 is used for receiving the liquid from the liquid supply mechanism on the base station 600, and the liquid enters the reservoir 110 of the machine body 100 after passing through the liquid adding assembly 300.

Therefore, when the liquid is added into the liquid storage tank 110, the top opening of the liquid storage tank 210 moves to the position below the liquid supply mechanism of the base station 600, the machine body 100 and the base station 600 do not need to be sealed, the butt joint precision requirement between the machine body 100 and the base station 600 is greatly reduced, the fault tolerance rate is high, the success rate of liquid adding is effectively improved, and the liquid adding machine has the advantage of convenience in liquid adding.

Specifically, when the liquid container 200 is driven by the driving mechanism 400, the liquid container 200 may move toward or away from the machine body 100, so as to drive the liquid container 200 to switch between the first state and the second state. That is, the driving mechanism 400 serves to generate an external force that drives the liquid container 200 to switch between the first state and the second state.

In the present embodiment, the driving mechanism 400 has various configurations, and may be a rack and pinion mechanism, a hydraulic cylinder, an air cylinder, or the like.

When the driving mechanism 400 is a rack and pinion mechanism, the rack and pinion mechanism (not shown) includes a rack (not shown) and a pinion (not shown) that are engaged with each other. Wherein, the rack can be fixedly arranged on the outer wall of the liquid container 200 or detachably arranged on the outer wall of the liquid container 200. The gear is connected to a driving motor (not shown), and when the gear is driven by the driving motor to rotate, the rack drives the liquid container 200 to move, so that the liquid container 200 is switched between the first state and the second state.

A guide unit (not shown) for guiding the movement of the liquid container 200 is further disposed between the liquid container 200 and the machine body 100. Specifically, the guiding unit includes a guiding rib and a guiding groove, one of the guiding rib and the guiding groove is disposed in the machine body 100, and the other is disposed on the outer wall of the liquid container 200. Wherein, the guide ribs and the guide grooves are distributed along the front-back direction of the machine body 100. The "front and rear" means the forward and backward directions of the body 100, wherein the forward direction of the body 100 is the front direction, and the backward direction of the body 100 is the rear direction.

Further, a limiting unit (not shown) is further disposed between the liquid container 200 and the machine body 100, and the limiting unit is a pair of rubber limiting blocks fixedly disposed in the machine body 100. In this embodiment, the liquid container 200 is linearly reciprocated, and a pair of rubber stoppers defines the movement limit position of the liquid container 200.

When the driving mechanism 400 is a hydraulic cylinder, the hydraulic cylinder includes a hydraulic cylinder body and a piston rod, and the piston rod makes a linear reciprocating motion in the hydraulic cylinder body. The free end of the piston rod is connected to the liquid container 200, thereby driving the liquid container 200 to switch between the first state and the second state. A first stroke sensor (not shown) is further disposed in the body 100, and the first stroke sensor is used for sensing a movement position of the piston rod, so as to define a position of the liquid container 200.

When the driving mechanism 400 is a cylinder, the cylinder includes a cylinder body and a telescopic shaft, and the telescopic shaft makes a linear reciprocating motion in the cylinder body. The free end of the telescopic shaft is connected with the liquid container 200, so as to drive the liquid container 200 to switch between the first state and the second state. Wherein, a second stroke sensor (not shown) is further disposed in the body 100, and the second stroke sensor is used for sensing the movement position of the telescopic shaft, so as to limit the position of the liquid container 200.

Regarding the structure of the liquid feeding assembly 300, in an embodiment, please refer to fig. 4, the liquid feeding assembly 300 includes a first pump body 320, a first tube 330 and a second tube 340. The first pump body 320 is disposed in the body 100 and has a first inlet and a first outlet. The first tube 330 is used to communicate the first inlet with the reservoir 210, and the second tube 340 is used to communicate the first outlet with the inner cavity of the reservoir 110.

When the liquid storage tank 110 is filled with liquid, the liquid supply mechanism of the base station 600 injects the liquid into the liquid storage tank 210, and the liquid entering the liquid storage tank 210 enters the liquid storage tank 110 of the machine body 100 through the first tube 330 and the second tube 340 under the action of the suction force provided by the first pump body 320, so that the liquid filling operation of the liquid storage tank 110 is realized.

In another aspect, referring to fig. 5, the liquid feeding assembly 300 comprises a liquid feeding tube 310, and the reservoir 210 is connected to the inner cavity of the liquid storage tank 110 through the liquid feeding tube 310, wherein the liquid storage tank 110 is disposed lower than the reservoir 210. When the liquid storage tank 110 is filled with liquid, after the liquid supply mechanism of the base station 600 injects the liquid into the liquid storage tank 210, the liquid enters the liquid storage tank 110 through the liquid supply pipe 310 under the action of gravitational potential energy, so that the liquid supply operation of the liquid storage tank 110 is realized.

Of course, the liquid feeding assembly 300 can also be in other structural forms, and the structure that can convey the liquid in the liquid storage tank 210 to the liquid storage tank 110 is the protection scope of the present invention, which is not described herein in detail.

In this embodiment, the priming assembly 300 preferably includes the first pump body 320. Accordingly, when the liquid tank 110 is filled with liquid, the scrubber sucks the liquid in the liquid tank 210 into the liquid tank 110 through the first pump 320.

Further, referring to fig. 6 and 8, a liquid outlet 230 is disposed on the liquid container 200 and is communicated with the liquid storage tank 210, and the liquid outlet 230 is connected with the liquid adding assembly 300 for discharging the liquid in the liquid storage tank 210. The liquid outlet 230 is located at the bottom of the liquid container 200, wherein the bottom of the liquid container 200 is a slope surface, and the liquid outlet 230 is located at the lowest position of the slope surface. Therefore, when the liquid taking of the liquid storage tank 110 is completed, no residual liquid exists in the liquid storage tank 210, and bacteria breeding caused by residual liquid accumulation in the liquid storage tank 210 is effectively avoided.

In this embodiment, the base station 600 will fill the reservoir 210 of the fluid container 200 only when the fluid container 200 is in the second state. To know whether the liquid container 200 is in the second state, it is determined whether the liquid can be filled into the liquid reservoir 210. In this embodiment, the liquid container 200 is provided with a first sensor (not shown), and the liquid supply mechanism of the base station 600 is provided with a second sensor (not shown) cooperating with the first sensor.

Specifically, the first sensor is electrically connected to a first controller (not shown) on the scrubber machine, and the second sensor is electrically connected to a second controller (not shown) on the base station 600. When the liquid container 200 is in the second state, the first sensor and the second sensor form a communication connection, the first controller controls the first pump body 320 of the liquid adding assembly 300 to work, and the second controller controls the liquid supplying mechanism of the base station 600 to supply liquid to the liquid storage tank 210.

The first sensor and the second sensor may be infrared sensors or hall sensors. When the first sensor and the second sensor are infrared sensors, the first sensor can be regarded as an infrared emitter, and the second sensor is an infrared receiver cooperating with the infrared emitter.

Further, the scrubber also includes a level sensor (not shown) for detecting the level of liquid in the reservoir 210. The level sensor may be located on the liquid container 200, for example, on an inner wall or an outer wall of the liquid container 200. Specifically, when the liquid level sensor is disposed on the liquid container 200, the liquid level sensor may be an infrared sensor or a TOF sensor. Taking a TOF sensor as an example, the TOF sensor is disposed on the top of the liquid storage tank 210, and the TOF sensor can realize the measurement of the liquid level height of the liquid storage tank 210 in a non-contact manner.

Of course, the liquid level sensor may also be disposed at the liquid supply mechanism of the base station 600, and when the liquid supply mechanism supplies liquid, the liquid level sensor may detect the liquid level height of the liquid storage tank 210 in real time. When the liquid level sensor is provided at the liquid supply mechanism of the base station 600, the liquid level sensor is preferably a TOF sensor.

Further, the liquid container 200 or the base station 600 is further provided with an alarm element (not shown), and when the liquid level sensor is triggered, the alarm element triggers an alarm. Specifically, when the liquid level sensor detects that the liquid level in the reservoir 210 is continuously increased or kept constant, the liquid level sensor is triggered and the alarm element alarms.

In the present embodiment, referring to fig. 8 and fig. 6, a mounting cavity 220 for accommodating the first sensor is disposed on the liquid container 200, and the mounting cavity 220 and the liquid storage tank 210 are distributed back to back. When the first sensor is an infrared sensor, since the liquid supply mechanism of the base station 600 is located above the liquid container 200, the first sensor tends to emit infrared rays upwards, and at this time, the top of the installation cavity 220 needs to be made of a transparent material for the infrared rays to penetrate through. Of course, the top of the installation cavity 220 may also be an opening for infrared rays to pass through.

Further, a recharge sensor (not shown) may be disposed within the mounting cavity 220 and used to guide the scrubber back to the base station 600. At this time, the wall around the installation cavity 220 needs to be made of a light-transmitting material so that the light emitted by the recharging sensor can be recognized by the base station 600, thereby guiding the scrubber to return to the base station 600. Of course, the liquid container 200 may be made of a transparent material.

Further, the liquid level sensor may also be disposed in the mounting cavity 220, and in this case, the first sensor, the refill sensor and the liquid level sensor are all disposed in the mounting cavity 220. Referring to fig. 6, in the present embodiment, the first sensor, the refill sensor and the liquid level sensor form a sensor assembly 500, so that the space of the installation cavity 220 is effectively utilized, the structure is more compact, and the assembly is convenient.

When the machine body 100 of the floor washing machine performs liquid adding operation, the floor washing machine is located in the placing area, when the second sensor detects that the liquid container 200 is in the second state, the liquid outlet of the liquid supply mechanism is communicated with the top opening of the liquid storage tank 210, the second sensor sends a signal to the second controller, and the second controller controls the second pump body to be opened so as to add liquid to the liquid storage tank 210.

In the present embodiment, please refer to fig. 10, a liquid injection nozzle 610 is disposed on the liquid outlet, and the liquid injection nozzle 610 is located above the liquid storage tank 210. The overall dimension of the liquid filling nozzle 610 is much smaller than the top opening of the liquid storage tank 210, so that liquid filling operation can be realized without high butting precision during liquid filling operation.

In order to allow for easy adjustment of the height of the pouring nozzle 610 for better engagement with the reservoir 210. Further, the liquid injection nozzle 610 is disposed on the base station 600 via an elevating unit (not shown) for driving the liquid injection nozzle 610 to reciprocate linearly in the tank depth direction of the liquid storage tank 210.

When the liquid adding operation is finished, the liquid filling nozzle 610 stops operating, and the first controller controls the driving mechanism 400 to drive the liquid container 200 to return to the inside of the machine body 100.

When the liquid storage tank 110 is full or the first tube 330 or the second tube 340 of the liquid adding assembly 300 is blocked, and the liquid level sensor detects that the liquid level in the liquid storage tank 210 is too high and does not descend, the base station 600 controls the liquid adding nozzle 610 to stop the liquid adding action through the second controller, and extends the liquid adding nozzle 610 into the liquid storage tank 210 through the lifting unit, so that the liquid in the liquid storage tank 210 is pumped back to the base station, and meanwhile, an alarm is given to prompt a user to maintain the liquid storage tank 210 and corresponding pipelines.
