Description

TECHNICAL FIELD

[0002] With the improvement of modern people's living standards, in recent years, there are many cleaning devices on the market, with various categories, such as scrubber, sweeping robot, etc. The scrubber on the market usually has a cleaning liquid tank, and the water or cleaning liquid in the cleaning liquid tank flows to the scrubber brush or mop to perform cleaning work. In order to detect whether the liquid in the cleaning liquid tank flows to the brush normally, a sensor for detecting water flow is usually arranged in the flow channel between the cleaning liquid tank and the brush. Due to the low accuracy of the current sensor, in addition, a water decomposition module is usually arranged in the cleaning liquid tank, and a large amount of bubbles generated by the water decomposition module will seriously interfere with the detection accuracy of the sensor when being sucked into the flow channel, causing the sensor to falsely report no water signal, which brings a bad user experience.

[0041] In this document, "equal", "same", and the like, are not strictly limited in the mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and allowed in manufacturing or use.

[0042] Unless otherwise stated, numerical ranges in this document include the entire range between the two endpoints, as well as several sub-ranges contained therein.

[0043] The present disclosure provides a cleaning device, which can be a scrubber, a washing machine, or the like, for cleaning a work surface, such as a floor, a sofa, a carpet, or the like, that needs to be cleaned. The cleaning device includes a machine body configured to be inclined with respect to the work surface during operation. A cleaning liquid tank and a docking device are provided on the machine body, and the cleaning liquid tank is docked on the machine body through the docking device. The cleaning device further includes a floor brush assembly connected to the machine body and configured to clean the work surface. The cleaning liquid tank provides clean water, cleaning liquid, or the like, to the floor brush assembly through the docking device.

[0044] The docking device is provided with a first docking cavity. The first docking cavity is provided with a first docking port which is docked with the first pipe joint of the cleaning liquid tank. The cavity bottom of the first docking cavity includes a first area adjacent to the first pipe joint and a second area away from the first pipe joint. The distance from the end face of the first pipe joint to the first area is smaller than the distance from the first pipe joint to the second area. The second area is provided with a discharge port. The liquid in the cleaning liquid tank is configured to flow out through the discharge port and be provided to the floor brush assembly.

[0045] The machine body is further provided with a first detection device which is in communication with the discharge port and is configured to detect the liquid discharged from the discharge port and detect whether the liquid in the cleaning liquid tank flows out normally.

[0046] The cleaning liquid tank is provided with a hydrolysis module for electrolytic disinfection of the liquid. The hydrolysis module generates a large amount of bubbles in the liquid. The bubbles are sucked into the first docking cavity and then enter the first detection device. When the machine body is inclined, the bubbles are easily accumulated in the first docking cavity. When a large number of bubbles enter the first detection device from the first docking cavity through the discharge port, interference is caused, resulting in false reporting of no water signal by the first detection device.

[0047] In the cleaning device of the present disclosure, the first area of the docking device is closer to the first pipe joint relative to the second area, which makes the distance from the end face of the first pipe joint to the first area smaller, thereby greatly reducing the space for the existence of bubbles. When the liquid in the cleaning liquid tank flows out through the discharge port of the second area, the number of bubbles flowing out is greatly reduced, thereby reducing the influence of the bubbles on the first detection device and improving the accuracy of the first detection device.

[0048] The technical solutions of the present disclosure will be described in detail below with reference to the specific structure of the accompanying drawings. Figures 1 to 4

[0049] In some embodiments of the present disclosure, the cleaning device includes a machine body and a floor brush assembly. The floor brush assembly is movably connected to one end of the machine body and is used to clean the working surface. When the cleaning device is in operation, the floor brush assembly is attached to the working surface, and the user pushes the floor brush assembly by holding the machine body. The machine body can rotate relative to the floor brush assembly.

[0050] As shown in Figure 1 The machine body of the cleaning device is provided with a cleaning liquid tank 1 and a docking device 2. The cleaning liquid tank 1 stores liquid used for cleaning the working surface. The cleaning liquid tank 1 is provided with a first pipe joint 11 which can be docked with the docking device 2. After docking, the liquid in the cleaning liquid tank 1 can flow to the floor brush assembly through the docking device 2. The floor brush assembly can spray the liquid onto the working surface or the brush body of the floor brush assembly, thereby improving the cleaning effect.

[0051] As shown in Figure 2 , Figure 3 ​As shown, the docking device 2 is provided with a first docking cavity 21, the first docking cavity 21 is provided with a first docking port 211, the first docking port 211 is used for docking with the first pipe joint 11 of the cleaning liquid bucket 1; the first docking cavity 21 is also provided with a discharge port 214, the liquid in the cleaning liquid bucket 1 is configured to flow to the floor brush assembly through the discharge port 214. The liquid in the cleaning liquid bucket 1 enters the first docking cavity 21 through the first pipe joint 11, and then flows to the floor brush assembly through the discharge port 214.

[0052] In detail, as shown in Figure 3 、 Figure 4 , the first docking cavity 21 includes a first end and a second end, and the first docking port 211 is located at the first end. The cavity bottom of the first docking cavity 21 includes a first area 212 adjacent to the first pipe joint 11, and a second area 213 away from the first pipe joint 11, and the cavity bottom of the first docking cavity 21 is the second end. The distance from the end face of the first pipe joint 11 to the first area 212 is less than the distance from the first pipe joint 11 to the second area 213. The distance between the first area 212 and the first docking port 211 is relatively close, occupying the space in the first docking cavity 21. The second area 213 is relatively far away from the first docking port 211, and the discharge port 214 is arranged in the second area 213 and has a certain distance from the first docking port 211, which is beneficial to the smooth flow of the liquid from the first docking port 211 to the discharge port 214. That is, the first area 212 of the cavity bottom of the first docking cavity 21 is higher than the second area 213 in the height direction.

[0053] In a preferred embodiment, as shown in Figure 1 , the first pipe joint 11 is arranged at the bottom of the cleaning liquid bucket 1, and the first area 212 and the second area 213 of the first docking cavity 21 are located below the first docking port 211, which is beneficial to the discharge of the liquid in the cleaning liquid bucket 1. The second area 213 is located lower, which is beneficial to the gathering of the liquid to the discharge port 214.

[0054] The cleaning liquid bucket 1 can be provided with an air pressure balance port to balance the air pressure in the cleaning liquid bucket 1 with the outside air pressure, so that the liquid can be smoothly discharged. The cleaning liquid bucket 1 can be provided with an electrolysis module, and the electrolysis module is used for electrolyzing the liquid in the cleaning liquid bucket 1, so that a disinfecting substance for disinfecting the liquid can be generated, and a large amount of bubbles will be generated in the liquid during the electrolysis process.

[0055] In an embodiment of the present disclosure, the cavity bottom of the first docking cavity 21 is configured to tilt synchronously with the body; when the cavity bottom is in a tilted state, the first region 212 is located above the second region 213, and the bubbles are concentrated above the first region 212 due to buoyancy, and the space between the first region 212 and the first docking interface 211 is small, thereby reducing the space for the bubbles to exist, reducing the interference of air on the first detection device 3, improving the accuracy of the first detection device 3, and avoiding the first detection device 3 from misjudging that there is no water in the cleaning liquid barrel 1 when the liquid in the cleaning liquid barrel 1 is less.

[0056] In an embodiment of the present disclosure, when the cavity bottom is in a tilted state, the first space between the upper position of the end surface of the first pipe joint 11 and the upper position of the cavity wall of the first docking interface 211 and the upper position of the first region 212, and the second space between the lower position of the end surface of the first pipe joint 11 and the lower position of the cavity wall of the first docking interface 211 and the second region 213 are formed, and the first space is smaller than the second space, thereby being capable of storing fewer bubbles. Here, the upper position and the lower position refer to the upper position and the lower position in the tilting direction when the body is in a tilted state.

[0057] In an embodiment of the present disclosure, for the sake of clarity and simplicity of the present disclosure, the side facing the user is referred to as the rear side, and the side away from the user is referred to as the front side when the cleaning device is in a working state. As shown in Figure 1 Fig. 2 shows a schematic view of the cleaning liquid barrel 1 detached from the body, and the front side of the body is provided with a mounting cavity for mounting the cleaning liquid barrel 1. The first region 212 is arranged on the side of the cavity bottom of the first docking cavity 21 away from the body; the second region 213 is arranged on the side of the cavity bottom of the first docking cavity 21 adjacent to the body; and the body is configured to tilt backward when working, so that the first region 212 is located above the second region 213 when working, and the bubbles are concentrated in the higher position in the first docking cavity, i.e., in the first space.

[0058] In an embodiment of the present disclosure, the first detection device 3 can be a pressure sensor for detecting whether the water outlet 214 discharges water. The first detection device 3 can also use other types of sensors, such as photoelectric sensors, which are not limited in the present disclosure.

[0059] In an embodiment of the present disclosure, as shown in Figure 2 Fig. 3, the first pipe joint 11 of the cleaning liquid barrel 1 is configured to extend into the first docking cavity 21 when it is docked with the first docking interface 211, i.e., the first pipe joint 11 is docked with the first docking cavity 21, and a gap is left between the first pipe joint 11 and the first region 212 for the liquid to pass through, thereby avoiding the first region 212 from blocking the first pipe joint 11 and affecting the flow rate of the liquid.

[0060] The gap between the first pipe joint 11 and the first area 212 is prone to retaining air bubbles. By increasing the flow rate of the liquid in the first docking cavity 21, the air bubbles in the gap can be removed. A small amount of air bubbles has little effect on the accuracy of the first detection device 3 and can be ignored.

[0061] In some embodiments of the present disclosure, as shown in Figure 3 , Figure 4 The second area 213 of the first docking cavity 21 is also provided with an injection port 215. The docking device 2 is configured to supplement the cleaning liquid tank 1 with liquid through the injection port 215. When the liquid in the cleaning liquid tank 1 is insufficient, liquid can be transported to the first docking cavity 21 through the injection port 215. The liquid enters the first pipe joint 11 of the cleaning liquid tank 1 through the first docking port 211 of the first docking cavity 21.

[0062] The liquid outlet and the liquid inlet of the cleaning liquid tank 1 can be realized through the first pipe joint 11. This makes the structure of the cleaning liquid tank and the fuselage simple, facilitates the installation process of the cleaning liquid tank and the fuselage, and reduces the production and manufacturing difficulty of the cleaning liquid tank and the fuselage.

[0063] In some embodiments of the present disclosure, as shown in Figure 4 The cavity bottom of the first docking cavity 21 includes a first bottom surface located in the first area 212 and a second bottom surface located in the second area 213. The discharge port 214 is arranged on the second bottom surface of the second area 213, thereby not occupying space in the height direction.

[0064] In some embodiments of the present disclosure, the first area 212 is an inclined surface. The closer the first area 212 is to the second area 213, the lower the height of the part. Specifically, the first bottom surface of the first area 212 gradually extends in the direction of the first pipe joint 11 from the position adjacent to the second bottom surface to the position away from the second bottom surface, which is beneficial to the liquid in the first docking cavity 21 converging to the second area 213.

[0065] In some embodiments of the present disclosure, as shown in Figure 4 The injection port 215 is arranged on the cavity wall of the first docking cavity 21 corresponding to the second area 213. The cavity wall of the first docking cavity 21 extends from the first docking port 211 to the first area 212 and the second area 213. The injection port 215 needs to be arranged on the cavity wall, which occupies space in the height direction of the first docking cavity 21. The second area 213 is lower than the first area 212, which can extend the cavity wall to provide space for the injection port 215. The arrangement of the first area 213 can ensure the space for the injection port 215 while reducing the space for air bubbles in the first docking cavity 21.

[0066] In some embodiments of the present disclosure, as shown in

[0067] In some embodiments of the present disclosure, as shown in Figure 3 、 Figure 4 An injection pipe 217 is formed outside the first docking interface 211, and the injection pipe 217 is in communication with the first docking cavity 21 to inject liquid into the first docking cavity 21 and supplement the cleaning liquid tank 1. The injection pipe 217 and the first docking interface 211 can be formed as an integral structure, and the injection pipe 217 forms an injection port 215 in the first docking interface 211.

[0068] In some embodiments of the present disclosure, as shown in Figure 2 A first valve 12 is arranged in the first pipe joint 11 of the cleaning liquid tank 1. When the first pipe joint 11 is not docked with the first docking interface 211, the first valve 12 closes the first pipe joint 11 to prevent the liquid in the cleaning liquid tank 1 from leaking. The second end of the first docking cavity 21 is provided with a first top rod 216 extending towards the first docking interface 211; the first top rod 216 is configured to push the first valve 12 to move to an open position after the first pipe joint 11 is docked with the first docking interface 211.

[0069] In detail, as shown in Figure 2 The first valve 12 of the cleaning liquid tank 1 includes a valve core 121 arranged in the first pipe joint 11 by an elastic member 122. The elastic member 122 causes the valve core 121 to be in a closed state by elastic force. The elastic member 122 includes, but is not limited to, a compression spring, a spring sheet, etc. When the first pipe joint 11 is docked with the first docking interface 211, the first top rod 216 can push the valve core 121 of the first valve 12 to move the valve core 122 away from the first docking cavity 21 against the action of the elastic member, thereby opening the first valve 12.

[0070] When the cleaning liquid tank 1 is disassembled, the first top rod 216 moves away from the valve core 121 of the first valve 12, and the valve core 121 is reset under the elastic force of the elastic member 122, thereby closing the first valve 12. The arrangement of the first valve 12 and the first top rod 216 can make the cleaning liquid tank 1 more convenient to disassemble and assemble, and improve the user experience.

[0071] In a specific embodiment of the present disclosure, as shown in Figure 2 、 Figure 3As shown, the first top rod 216 is arranged at a middle position of the second end of the first docking cavity 21, and the first area 212 and the second area 213 are configured to be connected to form a ring structure and surround the first top rod 216. In detail, the first docking cavity 21 has a circular cross section, the first area 212 and the second area 213 have an arc structure, and the area of the first area 212 is greater than that of the second area 213. The first top rod 216 can be arranged in a tapered structure, and the diameter of the first top rod 216 gradually decreases from the second end to the first end of the first docking cavity 21.

[0072] In other words, one end of the first top rod 216 is connected to the first area 212, and the other end extends to the first docking interface 211. The second area 213 is arranged at an edge position of the first docking cavity 21.

[0073] In one specific embodiment of the present disclosure, as shown in Figure 2 As shown, the first docking cavity 21 is provided with a filter 210 for filtering impurities in the liquid to avoid blockage of devices such as valves and water pumps through which the liquid passes. The filter 210 is located between the first end and the second end of the first docking cavity 21, and the liquid in the first docking cavity 21 is configured to flow from the first end to the second end through the filter 210, or from the second end to the first end through the filter 210.

[0074] Specifically, the filter 210 can be arranged in the gap between the first area 212 and the first docking interface 211, and extend to cover the second area 213, and the edge of the filter 210 cooperates with the inner wall of the first docking cavity 21. In a preferred embodiment, the shape of the filter 210 is adapted to the shape of the first docking interface 211. To ensure that the liquid passes through the filter 210. The filter 210 can be a conventional liquid filter such as a filter screen or a sponge, which is not limited in the present disclosure.

[0075] When the cleaning liquid tank 1 is docked with the docking device 2, the first pipe joint 11 of the cleaning liquid tank 1 is docked with the first docking interface 211 of the docking device 2, the first pipe joint 11 is inserted into the first docking interface 211, and the filter 210 is located between the first pipe joint 11 and the first area 212. The liquid flowing out of the first pipe joint 11 is filtered by the filter 210 and then discharged to the brush assembly through the discharge port 214. Here, the filter 210 and the first area 212 have a gap for the liquid to flow through. Preferably, in order to minimize the space for retaining bubbles, the gap here can be a small gap of no more than 2 mm.

[0076] In an embodiment of the present disclosure, the machine body of the cleaning device is further provided with a liquid supply channel, one end of the liquid supply channel is in communication with the discharge outlet 214, and the other end extends to the floor brush assembly. The liquid supply channel can include a drain pipe provided on the machine body. The discharge outlet 214 can extend downward of the first docking cavity 21 to form a joint, and the first detection device 3 is connected to the lower end of the discharge outlet 214. Liquid passes through the first detection device 3 and then enters the liquid supply channel and flows to the floor brush assembly.

[0077] The liquid supply channel is provided with a liquid supply pump for pumping liquid from the discharge outlet 214 to the floor brush assembly. The liquid supply pump provides power to the liquid in the liquid supply channel to make the liquid enter the first docking cavity 21 from the cleaning liquid tank 1, and then be transported to the floor brush assembly through the liquid supply channel from the discharge outlet 214 of the first docking cavity 21. The liquid supply pump can be a plunger pump, a peristaltic pump, etc., which is not limited in the present disclosure.

[0078] The cleaning device can be used with a base station. The cleaning device can be fitted on the base station, and the base station can be provided with functions of charging, cleaning, replenishing liquid, and discharging sewage of the cleaning device.

[0079] In an embodiment of the present disclosure, the cleaning device is configured to be docked with a base station (not shown in the figure), and the base station can replenish liquid into the cleaning liquid tank 1. In detail, a liquid replenishment channel is provided on the machine body of the cleaning device, one end of the liquid replenishment channel is docked with the injection inlet 215 of the docking device 2, and the other end is configured to be docked with the base station. The liquid replenishment channel is connected with a liquid replenishment pump, and the liquid replenishment pump provides power to the liquid in the liquid replenishment channel to make the liquid transported from the base station to the injection inlet 215, and then replenished into the cleaning liquid tank 1 through the first docking cavity 21 and the first pipe joint 11. The liquid replenishment pump can be provided on the cleaning device or on the base station. The liquid replenishment pump can be a plunger pump, a peristaltic pump, etc., which is not limited in the present disclosure.

[0080] In detail, when the liquid replenishment channel replenishes liquid into the cleaning liquid tank 1, the liquid supply channel is closed to avoid liquid flowing to the floor brush assembly. When the liquid supply channel supplies liquid to the floor brush assembly, the liquid replenishment channel is closed to avoid liquid leaking from the liquid replenishment channel. Control valves can be provided on the liquid supply channel and the liquid replenishment channel to open or close the liquid supply channel and the liquid replenishment channel. The control valves can be one-way valves, electromagnetic valves, etc. Alternatively, the liquid supply channel and the liquid replenishment channel can be directly controlled to open or close by the liquid supply pump and the liquid replenishment pump.

[0081] In detail, as shown in Figure 3 , Figure 4 The liquid replenishment channel includes an inlet pipe that cooperates with the injection pipe 217 of the docking device 2. The end of the inlet pipe away from the injection inlet 215 can be provided with a joint for docking with the base station.

[0082] In an embodiment of the present disclosure, as shown in Figure 1、 Figure 3 As shown in the drawings, the cleaning liquid tank 1 is further provided with a second pipe joint 13, which is independently arranged with the first pipe joint 11. The second pipe joint 13 is close to the first pipe joint 11, and both of them can be arranged on the bottom of the cleaning liquid tank 1. The docking device 2 is further provided with a second docking cavity 22. The second docking cavity 22 includes a second docking port 221 which is docked with the second pipe joint 13 of the cleaning liquid tank 1. When the cleaning liquid tank 1 is docked with the docking device 2, the first pipe joint 11 and the second pipe joint 13 are simultaneously docked on the docking device 2. When the cleaning liquid tank 1 is disassembled, the first pipe joint 11 and the second pipe joint 13 are simultaneously disengaged from the docking device 2, so that the installation and disassembly operation is convenient.

[0083] The machine body is further provided with a second detection device (not shown in the drawings) which is in communication with the second docking cavity 22, and is configured to detect the liquid entering the second docking cavity 22 from the cleaning liquid tank 1. The second detection device can detect the pressure of the liquid, and the amount of liquid in the cleaning liquid tank 1 can be judged by the pressure.

[0084] In one specific embodiment of the present disclosure, as shown in Figure 1 、 Figure 3 As shown in the drawings, the second pipe joint 13 of the cleaning liquid tank 1 is provided with a second valve (not shown in the drawings). When the second pipe joint 13 has not been docked with the second docking port 221, the second valve closes the second pipe joint 21, so as to avoid the leakage of the liquid in the cleaning liquid tank 1. The second docking cavity 22 is provided with a second ejector rod 222 which is configured to push the second valve to move to an open position after the second pipe joint 13 is docked with the second docking port 221. The specific structure and principle of the second valve are the same as those of the first valve 12, and the present disclosure will not be described here.

[0085] In one specific embodiment of the present disclosure, as shown in Figure 3 、 Figure 4 As shown in the drawings, the docking device 2 further includes a mounting seat 23 which is fixedly connected with the machine body. The first docking cavity 21 and the second docking cavity 22 are independently arranged on the same side of the mounting seat 23, i.e. the side close to the cleaning liquid tank 1. The discharge port 214 and the injection port 215 are arranged on the side of the mounting seat 23 away from the cleaning liquid tank 1. The edge of the mounting seat 23 can be provided with a fixing portion 231 which is fixedly connected with the machine body. The fixing portion 231 can be a screw hole, a key groove structure, etc.

[0086] In detail, as shown in Figure 3 、 Figure 4As shown, the edges of the first pair of interfaces 211 and the second pair of interfaces 221 extend towards the side close to the cleaning liquid tank 1, forming a convex joint, so as to facilitate the docking with the first pipe joint 11 and the second pipe joint 13 of the cleaning liquid tank 1. The first pipe joint 11 and the second pipe joint 13 also extend downward to form a convex joint. When docking, the first pipe joint 11 is inserted into the first pair of interfaces 211, and the second pipe joint 13 is inserted into the second pair of interfaces 221. The first pipe joint 11 and the first pair of interfaces 211, and the second pipe joint 13 and the second pair of interfaces 221 can be matched by a sealing structure to avoid liquid leakage. The docking device 2 can be a component integrally machined and formed, for example, by mold casting, or can be completed by machining. For this, this paper does not make limitation here.

[0087] In an embodiment of the present disclosure, the cleaning device can be provided with a control unit, the first detection device 3 can generate a water signal or a no water signal and send it to the control unit, and the second detection device can generate a water amount signal and send it to the control unit. The cleaning device can also be provided with a prompt device, a display device, etc. The control unit can send a control signal to the prompt device based on the no water signal, so that the prompt device reminds the user to supplement the liquid through voice, warning light, etc. The control unit can send a control signal to the display device based on the water amount signal, so that the display device displays the water amount in the cleaning liquid tank 1 to the user through the light belt, etc.

[0088] In the working process of the existing cleaning equipment, the liquid supply pump draws water from the cleaning liquid tank to the brush assembly at a certain flow rate. If no water signal is detected in the channel from the cleaning liquid tank to the brush assembly within a predetermined time, for example, 15 seconds, it is considered that the cleaning liquid tank is out of water.

[0089] In an embodiment of the present disclosure, the first detection device 3 is located on the drainage pipeline downstream of the discharge port 214, that is, in the liquid supply channel, and the liquid supply pump is used to provide power for liquid discharge. If the first detection device 3 outputs a no water signal for a predetermined time, the cleaning equipment outputs a water shortage prompt; wherein the liquid supply pump works at a first flow rate and a second flow rate within the predetermined time, and the second flow rate is greater than the first flow rate.

[0090] In detail, the power of the liquid supply pump can be adjusted to draw water from the cleaning liquid tank 1 at different flow rates. The detection time of the first detection device 3 is divided into a first predetermined time and a second predetermined time. Within the first predetermined time, for example, 10 seconds, the liquid supply pump draws water at a first flow rate, and then within the second predetermined time, for example, 5 seconds, the liquid supply pump draws water at a second flow rate. If the first detection device 3 continuously detects a no water signal within the first predetermined time and the second predetermined time, the control unit judges that the water tank is out of water.

[0091] The present disclosure also provides a docking device applied to the cleaning device described above. The cleaning device comprises a machine body configured to be inclined relative to a working surface during operation, and the docking device 2 is arranged on the machine body, further comprising a cleaning liquid tank 1 arranged on the machine body, and a first detection device 3, wherein the cleaning liquid tank 1 is provided with a first pipe joint 11;

[0092] The docking device 2 is provided with a first docking cavity 21, and the first docking cavity 21 is provided with a first docking port 211 which is docked with the first pipe joint 11 of the cleaning liquid tank 1; the cavity bottom of the first docking cavity 21 comprises a first area 212 adjacent to the first pipe joint 11 and a second area 213 away from the first pipe joint 11; the distance from the end face of the first pipe joint 11 to the first area 212 is less than the distance from the first pipe joint 11 to the second area 213; the second area 213 is provided with a discharge port 214, and the liquid in the cleaning liquid tank 1 is configured to flow out through the discharge port 214; the first detection device 3 is in communication with the discharge port 214 and is configured to detect the liquid discharged from the discharge port 214.

[0093] The specific structure and principle of the docking device provided by the present disclosure can be referred to the cleaning device described above in the present specification, therefore, the present disclosure will not be described here.

[0094] The technical solutions adopted by the present disclosure will be described below in combination with specific application scenarios to help understanding. In the following application scenarios, the cleaning device is taken as an example of a scrubber.

[0095] Application scenario

[0096] When the scrubber is in operation, the user holds the machine body to push the brush assembly to walk on the ground to clean the ground, and the machine body can be rotated relative to the brush assembly to be inclined relative to the ground to facilitate the user to operate. During the operation, the water electrolysis module in the cleaning liquid tank 1 electrolyzes and disinfects the liquid and generates a large amount of bubbles, the liquid in the cleaning liquid tank 1 enters the first docking cavity 21 of the docking device 2, and then enters the liquid supply channel from the discharge port 214, and the liquid is pumped to the brush assembly by the liquid supply pump for cleaning the ground. The first detection device 3 connected to the discharge port 214 detects whether the liquid is discharged from the discharge port 214, and the control unit judges whether the liquid in the cleaning liquid tank 1 is discharged based on this.

[0097] When the machine body is inclined, the bubbles discharged from the cleaning liquid tank 1 will accumulate in the first docking cavity 21. The first area 212 reduces the internal space of the first docking cavity 21, and only a small amount of bubbles in the first docking cavity 21 is discharged from the discharge port 214 and enters the first detection device 3, which has little effect on the first detection device 3, and is conducive to ensuring the accuracy of the first detection device 3. After the liquid in the cleaning liquid tank 1 is emptied, the first detection device 3 sends a waterless signal to the control unit, and the control unit reminds the user to supplement the liquid to the cleaning liquid tank 1 based on the waterless signal.

Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical application, or technical improvement over the prior art, or to enable others skilled in the art to understand the embodiments disclosed herein.
