Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more particularly to a floor brush assembly and cleaning equipment. Background Technology

[0002] Dual-roller floor scrubbers are widely used in homes, offices, shopping malls, and other places because of their higher cleaning efficiency.

[0003] In related technologies, dual-brush floor scrubbers include a front brush, a rear brush, and a water spray structure. The dual-brush floor scrubber can move forward or backward to clean the floor by friction between the front and rear brushes. The water spray structure can be used to spray water onto the front and rear brushes respectively to humidify them and improve the cleaning effect.

[0004] However, in related technologies, when a dual-brush floor scrubber moves forward or backward, the water spraying structure sprays water from both the forward and rear brushes, making it impossible to adjust the water output accordingly. This results in a significant amount of water residue remaining on the floor after the scrubber has cleaned it. Utility Model Content

[0005] In view of the above problems, this application provides a floor brush component and cleaning device to reduce water stains on the ground without affecting the cleaning power of the floor brush component.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A first aspect of this application provides a cleaning device, including a body assembly and a floor brush assembly; one end of the body assembly is grippable by a person, and the other end is rotatably connected to the floor brush assembly, the floor brush assembly comprising:

[0008] Ground brush body;

[0009] A cleaning component is disposed on the floor brush body, the cleaning component including a first cleaning element and a second cleaning element that are spaced apart along the front-back direction of the floor brush body;

[0010] The liquid supply assembly includes a first liquid supply pipe and a second liquid supply pipe, wherein the first liquid supply pipe is configured to supply liquid to the first cleaning component, the second liquid supply pipe is configured to supply liquid to the second cleaning component, and the liquid supply flow rate of the first liquid supply pipe and the second liquid supply pipe is adjustable.

[0011] When the floor brush assembly moves forward, the liquid supply flow rate of the first liquid supply pipe is greater than that of the second liquid supply pipe; when the floor brush assembly moves backward, the liquid supply flow rate of the first liquid supply pipe is less than that of the second liquid supply pipe.

[0012] The cleaning device provided in this application embodiment includes a liquid supply component in the floor brush assembly. The liquid supply component includes a first liquid supply pipe and a second liquid supply pipe. The first liquid supply pipe supplies liquid to a first cleaning component in the floor brush assembly, and the second liquid supply pipe supplies liquid to a second cleaning component in the floor brush assembly. The flow rates of the first and second liquid supply pipes are adjustable. When the floor brush assembly moves forward, the flow rate of the first liquid supply pipe is greater than that of the second liquid supply pipe, meaning the water content of the second cleaning component is less than that of the first cleaning component. This allows residual water on the first cleaning component to be absorbed by the following second cleaning component. When the floor brush assembly moves backward, the flow rate of the first liquid supply pipe is less than that of the second liquid supply pipe, again meaning the water content of the first cleaning component is less than that of the second cleaning component. This allows residual water on the second cleaning component to be absorbed by the following first cleaning component when the floor brush assembly moves backward. Therefore, regardless of whether the floor brush assembly moves forward or backward, the residual water on the floor can be reduced, thereby reducing the risk of slipping on water and improving the user experience.

[0013] In some embodiments, a push-pull member is provided at one end of the body assembly connected to the floor brush assembly. The push-pull member is movably connected to the floor brush body and can move back and forth relative to the floor brush body, pushing or pulling the floor brush body. Along the front-back direction of the floor brush body, the push-pull member is located between the first liquid supply pipe and the second liquid supply pipe. Both the first and second liquid supply pipes are flexible pipes. When the push-pull member moves the floor brush assembly forward under the action of an external force, the push-pull member squeezes the second liquid supply pipe so that the liquid supply flow rate of the second liquid supply pipe is less than the liquid supply flow rate of the first liquid supply pipe. When the push-pull member moves the floor brush assembly backward under the action of an external force, the push-pull member squeezes the first liquid supply pipe so that the liquid supply flow rate of the first liquid supply pipe is less than the liquid supply flow rate of the second liquid supply pipe.

[0014] With this configuration, when the push-pull component moves the floor brush assembly forward or backward under external force, it can squeeze the first or second liquid supply pipe to change the liquid supply flow rate of the first and second liquid supply pipes, thereby adjusting the water content of the first and second cleaning components when moving forward and backward. This method is simple, easy to implement, and low in cost.

[0015] In some embodiments, along the front-rear direction of the brush body, the brush body has a first limiting structure and a second limiting structure spaced apart, and the first limiting structure is disposed in front of the second limiting structure; the push-pull member is movably disposed between the first limiting structure and the second limiting structure, the second liquid supply line is disposed between the first limiting structure and the push-pull member, and the first liquid supply line is disposed between the second limiting structure and the push-pull member.

[0016] With this configuration, the movement of the push-pull component in the front-to-back direction is limited by the first and second limiting structures.

[0017] In some embodiments, the floor brush body is provided with a mating member for rotatably connecting with the body assembly, the mating member having a first rotating hole, the push-pull member having a first rotating shaft, and at least a portion of the structure of the first rotating shaft being located in the first rotating hole;

[0018] Both the first and second liquid supply pipes pass through the first rotary hole. The second and first liquid supply pipes are located in front of and behind the first rotating shaft, respectively, in the first rotary hole. Under the action of external force, the machine body assembly drives the first rotating shaft to move along the front-back direction to squeeze the first or second liquid supply pipe.

[0019] In some embodiments, the floor brush assembly further includes a mating member having a first rotating hole, the first rotating hole having a dimension in the front-rear direction greater than its dimension in the vertical direction; the push-pull member has a first rotating shaft, at least a portion of the structure of the first rotating shaft being rotatably connected to the first rotating hole, the push-pull member being rotatable relative to the mating member and moving in the front-rear direction under the action of an external force; wherein, along the front-rear direction of the floor brush body, the front side wall of the first rotating hole is formed as the first limiting structure, and the rear side wall of the first rotating hole is formed as the second limiting structure.

[0020] With this configuration, the push-pull component squeezes the second liquid supply pipe when it moves forward and squeezes the first liquid supply pipe when it moves backward, thereby changing the liquid supply flow rate of the first and second liquid supply pipes and thus changing the water content of the first and second cleaning components. Furthermore, by making the dimension of the first rotating hole in the front-to-back direction larger than its dimension in the vertical direction, the push-pull component has a certain amount of movement space in the front-to-back direction within the first rotating hole. In this way, adjusting the liquid supply flow rate of the first and second liquid supply pipes is simple, easy to implement, and low in cost.

[0021] In some embodiments, the mating member further includes a second rotating hole, and the first rotating hole and the second rotating hole are spaced apart along the left and right direction of the floor brush body; the push-pull member has a second rotating shaft that matches the second rotating hole, and the second rotating shaft is rotatably connected to the second rotating hole.

[0022] This configuration improves the reliability of the push-pull component's rotation relative to the brush body.

[0023] In some embodiments, the outline shape of the first rotary hole is elliptical; the outline shape of the second rotary hole is circular.

[0024] This configuration ensures that the push-pull component has room to move in the front-to-back direction while improving the rotational reliability of the push-pull component relative to the brush body. In addition, adjusting the liquid supply flow rate of the first and second liquid supply pipes is simple and low-cost.

[0025] In some embodiments, the liquid supply assembly further includes an inlet pipe and a three-way valve. One end of the inlet pipe is configured to be connected to a water source, and the other end of the inlet pipe is connected to the inlet end of the three-way valve. The first liquid supply pipe is connected to the first outlet end of the three-way valve, and the second liquid supply pipe is connected to the second outlet end of the three-way valve. The liquid flow rates of the first outlet end and the second outlet end are adjustable. The body assembly or the floor brush assembly is provided with a water tank, and the inlet end of the inlet pipe is connected to the water tank.

[0026] With this setup, the flow rate of the first and second liquid supply pipes can be controlled by a three-way valve, thereby improving the accuracy of adjusting the liquid supply flow rate.

[0027] In some embodiments, the cleaning device further includes a controller connected to the three-way valve and configured to control the flow rate of the liquid at the first and second outlets of the three-way valve.

[0028] This configuration allows the controller to automatically adjust the opening of the three-way valve according to specific needs, thereby improving the accuracy and automation of adjusting the liquid supply flow rate and enhancing the user experience.

[0029] In some embodiments, the cleaning device further includes a detection element connected to the controller via a signal. The detection element is configured to detect the forward or backward movement of the floor brush assembly, so that the controller controls the flow rate of the first and second water outlets based on the movement of the floor brush assembly.

[0030] With this setup, sensors or other detection devices determine whether the floor brush assembly is moving forward or backward, and transmit the movement status of the floor brush assembly to the controller via signals. The controller can then control the flow rate of the first and second water outlets based on the movement status of the floor brush assembly to reduce residual water stains on the floor.

[0031] In some embodiments, a liquid collection area is formed between the first cleaning component and the second cleaning component; the floor brush body is provided with a suction duct, the top of the liquid collection area is connected to the suction duct, and the liquid collection area is configured to be adjacent to at least one of the first cleaning component and the second cleaning component, so that liquid dripping into the liquid collection area can be absorbed by at least one of the first cleaning component and the second cleaning component.

[0032] With this setup, when the floor brush assembly stops moving, the suction negative pressure in the suction duct may become unstable or even shut down. This can easily cause liquid in the suction duct to flow back towards the ground under gravity. Liquid dripping from the floor brush assembly at a higher point in the suction duct can collect in the liquid collection area. The liquid in the collection area can be absorbed by either the first or second cleaning component, thus avoiding the problem of residual water stains on the ground where the floor brush assembly stops, thereby improving the user experience.

[0033] In some embodiments, the first cleaning element and the second cleaning element are both roller brushes; the central axes of the first cleaning element and the second cleaning element are 6-9 cm apart, or the outer contours of the first cleaning element and the second cleaning element are 0-6 mm apart.

[0034] This design reduces the distance between the first and second cleaning components, improving the structural compactness of the cleaning equipment.

[0035] In some embodiments, the floor brush assembly further includes a first drive motor and a second drive motor; both the first cleaning element and the second cleaning element are roller brushes; the first drive motor is connected to the first cleaning element and is configured to drive the first cleaning element to rotate about its own axis; the second drive motor is connected to the second cleaning element and is configured to drive the second cleaning element to rotate about its own axis.

[0036] This setup allows for independent control of the rotation speeds of the first and second cleaning components. The difference in rotation speed between the first and second cleaning components enables the floor brush assembly to move back and forth, thereby achieving the purpose of cleaning residual water stains on the floor.

[0037] A second aspect of this application provides a floor brush assembly, comprising:

[0038] The floor brush body is equipped with a suction duct.

[0039] A cleaning component is disposed on the floor brush body, the cleaning component including a first cleaning element and a second cleaning element that are spaced apart along the front-back direction of the floor brush body;

[0040] A liquid-gathering zone is formed between the first cleaning component and the second cleaning component. The top of the liquid-gathering zone is connected to the suction duct. The liquid-gathering zone is configured to be adjacent to at least one of the first cleaning component and the second cleaning component, so that liquid dripping into the liquid-gathering zone can be absorbed by at least one of the first cleaning component and the second cleaning component.

[0041] The floor brush assembly provided in this application embodiment, by arranging a first cleaning component and a second cleaning component spaced apart and parallel to each other along the front-back direction of the floor brush body, can support the floor brush body and clean the floor during the forward and backward pushing and pulling processes. In addition, the distance between the first and second cleaning components is reduced to form a liquid collection area between them, which is connected to one of the first and second cleaning components. In this way, on the one hand, the overall size of the floor brush assembly is reduced, improving the compactness of the overall layout of the floor brush assembly; on the other hand, when the floor brush assembly is stationary, liquid dripping from a height can be collected in the liquid collection area, and the liquid in the collection area can be absorbed by one of the adjacent first and second cleaning components, thereby avoiding the problem of residual water stains on the floor where the floor brush assembly rests, and thus improving the user experience.

[0042] In some embodiments, the floor brush assembly further includes:

[0043] The liquid supply assembly includes a first liquid supply pipe and a second liquid supply pipe, the first liquid supply pipe being configured to supply liquid to the first cleaning component, the second liquid supply pipe being configured to supply liquid to the second cleaning component (220), and the liquid supply flow rate of the first liquid supply pipe and the second liquid supply pipe being adjustable;

[0044] When the floor brush assembly moves forward, the liquid supply flow rate of the first liquid supply pipe is greater than that of the second liquid supply pipe; when the floor brush assembly moves backward, the liquid supply flow rate of the first liquid supply pipe is less than that of the second liquid supply pipe.

[0045] With this configuration, when the floor brush assembly moves forward, the water residue left by the first cleaning component can be absorbed by the following second cleaning component. When the floor brush assembly moves backward, the liquid supply flow rate of the first liquid supply pipe is less than that of the second liquid supply pipe, meaning that the water content of the first cleaning component is less than that of the second cleaning component. This allows the water residue left by the second cleaning component when the floor brush assembly moves backward to be absorbed by the following first cleaning component. Therefore, regardless of whether the floor brush assembly moves forward or backward, the water residue on the floor can be reduced, thereby improving the user experience.

[0046] In some embodiments, the first cleaning member and the second cleaning member are both roller brushes, and the first cleaning member and the second cleaning member can rotate relative to the floor brush body about their own axes, and the first cleaning member and the second cleaning member rotate in opposite directions;

[0047] The floor brush assembly also includes a first drive motor and a second drive motor.

[0048] The first cleaning component has a first receiving cavity inside, the second cleaning component has a second receiving cavity inside, and the first drive motor is disposed in the first receiving cavity and connected to the first cleaning component to drive the first cleaning component to rotate around its own axis.

[0049] The second drive motor is disposed in the second accommodating cavity and connected to the second cleaning component to drive the second cleaning component to rotate around its own axis.

[0050] This design offers several advantages. First, it makes pushing and pulling the floor brush assembly easier for users, eliminating the need for a power-assisted wheel and preventing secondary contamination from the wheel rolling across the floor. Second, it allows for independent control of the rotation speeds of the first and second cleaning components, facilitating pushing and pulling and saving time and effort. The speed difference between the first and second cleaning components enables the brush assembly to move back and forth, effectively cleaning residual water stains and enhancing the user experience. Furthermore, by housing the first drive motor within the first cleaning component and the second drive motor within the second cleaning component, the overall size and space occupied by the brush assembly can be reduced.

[0051] In some embodiments, the system further includes a controller electrically connected to the first drive motor and the second drive motor, respectively, and the controller is configured to control the rotational speeds of the first drive motor and the second drive motor, respectively.

[0052] This configuration allows the controller to independently control the rotational speeds of the first and second cleaning components via the first and second drive motors, respectively, thereby achieving a high degree of automation in the rotational speed regulation of the first and second cleaning components.

[0053] In some embodiments, the central axes of the first cleaning member and the second cleaning member are 6-9 cm apart, or the outer contours of the first cleaning member and the second cleaning member are 0-6 mm apart.

[0054] This design reduces the distance between the first and second cleaning components, improving the structural compactness of the cleaning equipment.

[0055] In some embodiments, when the first cleaning member and the second cleaning member are turned to face each other, a liquid suspension zone is formed between the first cleaning member and the second cleaning member; the liquid suspension zone is located below the liquid accumulation zone, and the liquid suspension zone and the liquid accumulation zone are interconnected; the liquid suspension zone is configured to gather the liquid between the first cleaning member and the second cleaning member, and to cause the gathered liquid to gather and move upward in the vertical direction.

[0056] With this setup, the relative movement of the first and second cleaning components can collect residual water stains on the ground into the liquid suspension zone. The liquid in the liquid suspension zone can be collected through the suction duct on the floor brush assembly, thereby reducing residual water stains on the ground.

[0057] In some embodiments, the connection between the liquid suspension zone and the liquid aggregation zone is located at the minimum gap between the first cleaning element and the second cleaning element.

[0058] This design prevents the liquid from accumulating in the pooling area from leaking out and reduces water stains remaining on the ground.

[0059] In some embodiments, the suction duct extends upward and has an air inlet at its bottom, which is located directly above the liquid collection area. Under suction force, the suction duct draws the liquid collected in the liquid suspension area sequentially through the liquid collection area and the air inlet into the suction duct.

[0060] This configuration, by setting the suction duct to extend vertically upwards without any bends, allows liquid and dust particles in the liquid suspension zone to be directly drawn into the suction duct, resulting in more concentrated suction. It also prevents dirt from getting stuck at the bends of the suction duct, thus achieving the purpose of cleaning the floor and reducing residual water stains on the floor.

[0061] In some embodiments, the floor brush assembly further includes two scraper blades, each scraper blade including a first scraper blade portion and a second scraper blade portion. The first scraper blade portion and the second scraper blade portion are respectively disposed on opposite sides of the air intake. The first scraper blade portion is in interference contact with the first cleaning component, and the second scraper blade portion is in interference contact with the second cleaning component. A liquid collection area is formed between the first scraper blade portion and the second scraper blade portion. The liquid collection area is located above the liquid collection area and communicates with the air intake.

[0062] With this configuration, the first scraper section and the second scraper section are used to scrape off dirt from the first and second cleaning components, respectively, and the dirt is accumulated in the liquid collection area. The dirt in the liquid collection area can be directly sucked out by the suction duct through the air inlet, so as to achieve self-cleaning of the first and second cleaning components.

[0063] In some embodiments, both the first scraper section and the second scraper section are closer to the air intake in the middle than at both ends; the middle of the liquid collection area is higher than the surrounding area, and the air intake is located in the middle region of the liquid collection area.

[0064] This design allows dirt to concentrate in the central area of ​​the collection zone and be drawn in through the air intake near the central area, thereby improving the efficiency of cleaning dirt in the collection zone.

[0065] In some embodiments, the floor brush assembly further includes a water distributor, which includes a first water distributor and a second water distributor. The first water distributor is disposed above the first cleaning component and extends along the length of the first cleaning component; the second water distributor is disposed above the second cleaning component and extends along the length of the second cleaning component.

[0066] The scraper is located below the water distributor; the water distributor and the scraper are an integral structure.

[0067] This design can improve the uniformity of moisture distribution on the first and second cleaning components, thereby enhancing the cleanliness of the floor. In addition, it improves the compactness of the structure, reduces installation steps, and lowers process costs.

[0068] A third aspect of this application provides a cleaning device, including a floor brush assembly and a body assembly as described in the second aspect above. One end of the body assembly is gripped by a person, and the other end is rotatably connected to the floor brush assembly. A push-pull member is provided at the end of the body assembly connected to the floor brush assembly. The push-pull member is movably connected to the floor brush body and can move back and forth relative to the floor brush body. Along the front-back direction of the floor brush body, the push-pull member is located between the first liquid supply pipe and the second liquid supply pipe.

[0069] When the push-pull member moves the floor brush assembly forward under the action of an external force, the push-pull member squeezes the second liquid supply pipe so that the liquid supply flow rate of the second liquid supply pipe is less than the liquid supply flow rate of the first liquid supply pipe; when the push-pull member moves the floor brush assembly backward under the action of an external force, the push-pull member squeezes the first liquid supply pipe so that the liquid supply flow rate of the first liquid supply pipe is less than the liquid supply flow rate of the second liquid supply pipe.

[0070] The cleaning equipment provided in this application embodiment has the same beneficial effects as the floor brush assembly described above, and will not be repeated here.

[0071] A fourth aspect of this application provides a cleaning device, including a floor brush assembly as described in the second aspect above.

[0072] The cleaning equipment provided in this application has the same beneficial effects as the floor brush assembly provided in the above embodiments, and will not be described again here.

[0099] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0100] Please refer to Figures 1 to 3 As shown in the figure, this application embodiment provides a cleaning device 10, which includes a floor brush assembly. The floor brush assembly includes a floor brush body 100 and a cleaning component 200 disposed on the floor brush body 100. The cleaning component 200 includes a first cleaning element 210 and a second cleaning element 220 spaced apart along the front-back direction of the floor brush body 100. The first cleaning element 210 and the second cleaning element 220 are arranged in parallel and side by side, and the first cleaning element 210 and the second cleaning element 220 are in direct contact with the ground. Thus, when the floor brush assembly is pushed forward and pulled back, the first cleaning element 210 and the second cleaning element 220 respectively generate friction with the ground to clean the ground.

[0101] The first cleaning component 210 and the second cleaning component 220 include, but are not limited to, roller brushes; for example, along the forward direction of the floor brush assembly, the first cleaning component 210 is located in front of the second cleaning component 220, for example, the first cleaning component 210 is a front roller brush and the second cleaning component 220 is a rear roller brush.

[0102] The structure of the floor brush assembly will be described below, taking the example that both the first cleaning component 210 and the second cleaning component 220 are roller brushes.

[0103] In some embodiments, the floor brush assembly further includes a liquid supply assembly 300. For example, the liquid supply assembly 300 includes a liquid supply pipe and a water pump connected to the liquid supply pipe. The water pump is connected to a water source. The liquid supply pipe is connected to the first cleaning component 210 and the second cleaning component 220, respectively. In this way, the cleaning liquid pumped into the liquid supply pipe by the water pump is sprayed onto the first cleaning component 210 and the second cleaning component 220, respectively, to increase the humidity of the first cleaning component 210 and the second cleaning component 220, thereby improving the removal of stubborn stains and dust on the ground.

[0104] The cleaning liquid can be pure tap water or a mixture of tap water with added detergent or fragrance. All of these are referred to as cleaning liquids. As long as they can assist in cleaning the floor and improve the cleaning effect and efficiency, there are no restrictions.

[0105] Since the liquid supply pipe supplies cleaning liquid to both the first cleaning component 210 and the second cleaning component 220 simultaneously, the water content of the first cleaning component 210 and the second cleaning component 220 is basically the same. However, if the water content of the first cleaning component 210 and the second cleaning component 220 is low, the cleaning effect will be poor; if the water content of the first cleaning component 210 and the second cleaning component 220 is high, there will be a lot of residual water stains on the ground during the cleaning process, which will affect the user's experience.

[0106] To address the aforementioned issues, the floor brush assembly provided in this application includes a liquid supply assembly 300 comprising a first liquid supply pipe 310 and a second liquid supply pipe 320. The first liquid supply pipe 310 supplies liquid to the first cleaning component 210, and the second liquid supply pipe 320 supplies liquid to the second cleaning component 220. In other words, the first liquid supply pipe 310 and the second liquid supply pipe 320 supply liquid to the first cleaning component 210 and the second cleaning component 220 respectively. The liquid supply flow rate of the first liquid supply pipe 310 and the second liquid supply pipe 320 is adjustable; that is, the first liquid supply pipe 310 can supply liquid according to the first liquid supply pipe 310... The first cleaning component 210 supplies cleaning liquid according to its needs. The second liquid supply pipe 320 can supply cleaning liquid according to the needs of the second cleaning component 220. For example, when the ground brush assembly moves forward, the liquid supply flow rate of the first liquid supply pipe 310 is greater than the liquid supply flow rate of the second liquid supply pipe 320, that is, the water output of the second liquid supply pipe 320 is reduced and the water output of the first liquid supply pipe 310 is increased; when the ground brush assembly moves backward, the liquid supply flow rate of the first liquid supply pipe 310 is less than the liquid supply flow rate of the second liquid supply pipe 320, that is, the water output of the first liquid supply pipe 310 is reduced and the water output of the second liquid supply pipe 320 is increased.

[0107] In this way, when the floor brush assembly is in the forward-pushing state, the water content of the first cleaning component 210 is greater than that of the second cleaning component 220. This allows the second cleaning component 220 to absorb the water residue left on the ground by the first cleaning component 210 as it moves forward following the first cleaning component 210. Conversely, when the floor brush assembly is in the backward-pushing state, the water content of the second cleaning component 220 is greater than that of the first cleaning component 210. This allows the first cleaning component 210 to absorb the water residue left on the ground by the second cleaning component 220 as it moves backward following the second cleaning component 220. Therefore, by making the flow rate of the first liquid supply pipe 310 and the second liquid supply pipe 320 adjustable, the amount of water residue left on the ground can be reduced during the forward and backward movement of the floor brush assembly, thereby improving the user experience. In addition, it can also save cleaning liquid and extend the runtime of the cleaning liquid in the built-in water tank of the cleaning equipment.

[0108] In some embodiments, the floor brush assembly also includes a booster wheel, which is disposed on the rear side of the second cleaning member 220 to provide support and assistance to the floor brush assembly. However, the booster wheel will roll over the cleaned floor, thereby causing secondary pollution to the cleaned floor. In addition, it will increase the overall size of the floor brush assembly, resulting in poor structural compactness of the floor brush assembly.

[0109] Based on the above problems, in this embodiment of the application, the assist wheel is eliminated from the floor brush assembly. Except for the first cleaning component 210 and the second cleaning component 220, which are in contact with the ground, the other structures in the floor brush assembly are not in contact with the ground. This allows the first cleaning component 210 and the second cleaning component 220 to not only roll and clean the ground but also support the floor brush body 100. This increases the pressure between the first cleaning component 210 and the second cleaning component 220 and the ground, and improves the friction between them, thereby enhancing the cleaning effect. Furthermore, it avoids the problem of the assist wheel causing secondary pollution to the cleaned ground, reduces the overall size of the floor brush assembly, improves its structural compactness, and eliminates the assist wheel, thus improving the steering flexibility of the floor brush assembly and preventing the steering flexibility from being restricted by the assist wheel.

[0110] It should be noted that, in the embodiments of this application, the distance between the first cleaning component 210 and the second cleaning component 220 can be minimized as much as possible, as long as the first cleaning component 210 and the second cleaning component 220 do not interfere with each other when rotating around their own axes. In this way, the overall size of the floor brush assembly can be further reduced and the structural compactness of the floor brush assembly can be improved.

[0111] In some embodiments, please continue to refer to Figures 1 to 3 As shown, the cleaning device 10 also includes a body assembly, which is rotatably connected to the floor brush assembly. A push-pull member 400 is provided at one end of the body assembly connected to the floor brush assembly. The push-pull member 400 is movably connected to the floor brush body 100, and can move back and forth relative to the floor brush body 100. For example, the push-pull member 400 can be rotatably connected to the floor brush body 100, so that the push-pull member 400 can rotate relative to the floor brush body 100 about an axis in a first direction, an axis in a second direction, and an axis in a third direction, respectively. Taking the floor brush body 100 as a reference, the first direction... If the first direction is forward and backward, the second direction is vertical, and the third direction is left and right, then the push-pull component 400 can rotate 360° in space. In addition, the push-pull component 400 can be rotatably connected to the floor brush body 100 near the geometric center, which can realize the flexible rotation of the floor brush assembly, and can also pressurize the entire floor brush assembly, increasing the pressure between the first cleaning component 210 and the second cleaning component 220 and the ground, thereby increasing the rolling friction between the first cleaning component 210 and the second cleaning component 220 and the ground, and thus improving the cleaning effect and efficiency.

[0112] In some embodiments, the push-pull member 400 can be a pivot, such as a cross pivot, so that the push-pull member 400 can drive the floor brush assembly to turn arbitrarily within a 360° range, or rotate in place for cleaning, or clean areas that are difficult to clean, such as narrow gaps or around pillars, thereby improving the cleaning effect.

[0113] In addition, the push-pull component 400 has a rotatable and swingable handle. In this way, the rotation and swing of the handle can be amplified by the push-pull component 400 and the floor brush body 100, and become the turning and sweeping of the floor brush body 100, thereby achieving a flexibility that traditional cleaning equipment cannot achieve.

[0114] In some embodiments, along the front-rear direction of the floor brush body 100, the second liquid supply pipe 320 is disposed on the front side of the push-pull member 400, and the first liquid supply pipe 310 is disposed on the rear side of the push-pull member 400, that is, the push-pull member 400 is located between the first liquid supply pipe 310 and the second liquid supply pipe 320, so that the body assembly can drive the first rotating shaft to move along the front-rear direction under the action of external force to squeeze the first liquid supply pipe or the second liquid supply pipe; specifically, when the push-pull member 400 drives the floor brush assembly to move forward under the action of external force, the push-pull member 400 squeezes the second liquid supply pipe 320 so that the liquid supply flow rate of the second liquid supply pipe 320 is less than the liquid supply flow rate of the first liquid supply pipe 310; when the push-pull member 400 drives the floor brush assembly to move backward under the action of external force, the push-pull member 400 squeezes the first liquid supply pipe 310 so that the liquid supply flow rate of the first liquid supply pipe 310 is less than the liquid supply flow rate of the second liquid supply pipe 320.

[0115] In other words, in addition to being able to rotate relative to the brush body 100, the push-pull member 400 can also move a small distance relative to the brush body 100 in the front-back direction. The first liquid supply pipe 310 and the second liquid supply pipe 320 are both flexible pipes. A portion of the flexible pipe of the first liquid supply pipe 310 is located directly behind the push-pull member 400 so that when pulled backward, the push-pull member 400 moves backward under the drive of the body assembly to squeeze the first liquid supply pipe 310. A portion of the flexible pipe of the second liquid supply pipe 320 is located directly in front of the push-pull member 400 so that when pushed forward, the push-pull member 400 moves backward and forward under the drive of the body assembly to squeeze the second liquid supply pipe 320. The front-back distance between the first liquid supply pipe 310 and the second liquid supply pipe 320 at the push-pull member 400 is equal to or slightly less than the movement distance of the push-pull member 400 relative to the brush body 100 in the front-back direction, so that the push-pull member 400 can squeeze the first liquid supply pipe 310 and the second liquid supply pipe 320 to different degrees.

[0116] Specifically, when the push-pull member 400 is in a forward-pushing state under external force, it squeezes the second liquid supply pipe 320 to reduce its liquid supply cross-section, thereby reducing the amount of cleaning liquid supplied to the second cleaning member 220. This results in the second cleaning member 220 having a lower water content than the first cleaning member 210. Thus, when the second cleaning member 220 moves according to the movement of the first cleaning member 210, it can absorb residual water stains on the ground, thereby reducing the amount of water residue on the ground. Conversely, when the push-pull member 400 is in a pulled-back state under external force, the push-pull member 400 squeezes the first liquid supply pipe 310 to reduce the liquid supply cross-section of the first liquid supply pipe 310, thereby reducing the amount of cleaning liquid supplied to the first cleaning member 210, so that the water content of the first cleaning member 210 is less than that of the second cleaning member 220. In this way, when the first cleaning member 210 moves according to the second cleaning member 220, the first cleaning member 210 can absorb the water stains remaining on the ground, thereby reducing the water stains remaining on the ground.

[0117] In addition, in this embodiment, by applying a pushing and pulling force to the push-pull member 400, the cross-sectional size of the first liquid supply pipe 310 or the second liquid supply pipe 320 is squeezed by the push-pull member 400, so as to adjust the liquid supply flow rate to the first cleaning member 210 and the second cleaning member 220 respectively, thereby changing the water content of the first cleaning member 210 and the second cleaning member 220. This method is simple, easy to implement, and low in cost.

[0118] In some embodiments, along the front-to-back direction, the floor brush body 100 has a first limiting structure and a second limiting structure spaced apart, with the first limiting structure positioned in front of the second limiting structure; a push-pull member 400 is movably disposed between the first limiting structure and the second limiting structure; a second liquid supply pipe 320 is disposed between the first limiting structure and the push-pull member 400; and a first liquid supply pipe 310 is disposed between the second limiting structure and the push-pull member 400. Thus, when the push-pull member 400 is in a forward-pushing state, the second liquid supply pipe 320 is pressed against the push-pull member 400. The first liquid supply pipe 310 is squeezed between the push-pull member 400 and the first limiting structure to change the cross-sectional size of the second liquid supply pipe 320. When the push-pull member 400 is in the pulled-back state, the first liquid supply pipe 310 is squeezed between the push-pull member 400 and the second limiting structure to change the cross-sectional size of the first liquid supply pipe 310. That is, the push-pull member 400 is limited in the front-back direction by the first limiting structure and the second limiting structure to restrict the movement of the push-pull member 400 in the front-back direction, thereby improving the reliability of changing the cross-sectional size of the first liquid supply pipe 310 and the second liquid supply pipe 320.

[0119] In some embodiments, such as Figure 2 and Figure 4As shown, the cleaning device 10 also includes a mating part 500, which, for example, is a fixed decorative cover disposed on the brush body 100; wherein, the mating part 500 has a first rotating hole 510, the size of the first rotating hole 510 in the front-back direction is larger than its size in the vertical direction; the push-pull member 400 has a first rotating shaft, at least a portion of the structure of the first rotating shaft is rotatably connected to the first rotating hole 510, and the push-pull member 400 can rotate relative to the mating part 500 and move in the front-back direction under the action of an external force; wherein, in the front-back direction, the front side hole wall 511 of the first rotating hole 510 is formed as a first limiting structure, and the rear side hole wall 512 of the first rotating hole 510 is formed as a second limiting structure.

[0120] For example, the outline shape of the first rotary hole 510 is elliptical, wherein the major axis of the ellipse extends along the front-back direction, and the minor axis extends along the vertical direction. For example, the second direction is as follows: Figure 3 The Z direction in the equation.

[0121] Thus, the radial dimension of the first rotating shaft is, for example, a rotating shaft whose vertical dimension matches that of the first rotating hole 510. The first rotating shaft is rotatably disposed within the first rotating hole 510. Since the dimension of the first rotating hole 510 in the front-rear direction is larger than the radial dimension of the first rotating shaft, the first rotating shaft can be displaced in the front-rear direction within the first rotating hole 510. A portion of the structure of the second liquid supply pipe 320 is disposed between the first rotating shaft and the front wall 511 of the first rotating hole 510. Part of the structure of tube 310 is located between the first rotating shaft and the rear wall 512 of the first rotating hole 510. When the push-pull member 400 moves forward, it squeezes the second liquid supply tube 320, and when it moves backward, it squeezes the first liquid supply tube 310, so as to change the liquid supply flow rate of the first liquid supply tube 310 and the second liquid supply tube 320 respectively, thereby changing the water content of the first cleaning member 210 and the second cleaning member 220. The method of adjusting the liquid supply flow rate of the first liquid supply tube 310 and the second liquid supply tube 320 is simple, easy to implement, and low in cost.

[0122] In some embodiments, please continue to refer to Figure 2 and Figure 5 As shown, the mating part 500 also includes a second rotating hole 520, and the first rotating hole 510 and the second rotating hole 520 are spaced apart along the left and right directions of the floor brush body 100; the push-pull member 400 has a second rotating shaft that matches the second rotating hole 520, and the second rotating shaft is rotatably connected to the second rotating hole 520; for example, the outline shape of the second rotating hole 520 is circular, and the second rotating shaft is a rotating shaft whose radial dimension matches the radial dimension of the circle, for example, the third direction is as follows Figure 1In the Y direction, the push-pull member 400 is only rotatably connected to the second rotating hole 520 through the second rotating shaft, while the first rotating shaft is rotatably connected to the first rotating hole 510 and also has a small gap in the front-back direction. This ensures the reliability of the push-pull member 400 relative to the brush body 100 rotation while adjusting the liquid supply flow of the first liquid supply pipe 310 and the second liquid supply pipe 320.

[0123] Therefore, in this embodiment, by setting the outline shape of the first rotating hole 510 on the mating part 500 to an ellipse and the outline shape of the second rotating hole 520 to a circle, the rotation reliability of the push-pull part 400 relative to the brush body 100 is improved while ensuring that the push-pull part 400 has room to move in the front-back direction. In addition, the method of adjusting the liquid supply flow of the first liquid supply pipe 310 and the second liquid supply pipe 320 is simple and low in cost.

[0124] In the embodiments of this application, the method of adjusting the liquid supply flow of the first liquid supply pipe 310 and the second liquid supply pipe 320 includes, but is not limited to, the method provided in the above embodiments. Other methods are also possible, as long as the water content of the first cleaning component 210 and the second cleaning component 220 can be changed during the pushing and pulling process of the floor brush assembly.

[0125] For example, in some other embodiments, please refer to Figure 2 As shown, the liquid supply assembly 300 also includes an inlet pipe 330 and a three-way valve 340. One end of the inlet pipe 330 is configured to be connected to a water source, and the other end of the inlet pipe 330 is connected to the inlet end of the three-way valve 340. The first liquid supply pipe 310 is connected to the first outlet end of the three-way valve 340, and the second liquid supply pipe 320 is connected to the second outlet end of the three-way valve 340. The liquid flow rates of the first outlet end and the second outlet end are adjustable. It can be understood that the liquid supply flow rates of the first liquid supply pipe 310 and the second liquid supply pipe 320 can be controlled by the three-way valve 340 to improve the accuracy of adjusting the liquid supply flow rate.

[0126] The three-way valve 340 can be referenced from the three-way valve 340 in related technologies, and no specific restrictions are made here.

[0127] In addition, the floor brush assembly also includes a controller, which is connected to the three-way valve 340. The controller is configured to control the flow rate of the first and second water outlets in the three-way valve 340. In other words, the three-way valve 340 can control the opening of the valve port electronically according to the control signal of the control valve, thereby changing the water output of the first and second water outlets. This can improve the accuracy and automation of adjusting the liquid supply flow rate, thereby improving the user experience.

[0128] Of course, during the pushing process, the controller can also be used to completely close the second outlet end of the three-way valve 340, so that no water flows out of the second outlet pipe; during the pulling process, the controller can also be used to completely close the first outlet end of the three-way valve 340, so that no water flows out of the first outlet pipe.

[0129] In some embodiments, a detection element is also included. For example, the detection element includes, but is not limited to, a position sensor detection element connected to the controller signal. The detection element is configured to detect the forward or backward movement state of the floor brush assembly, that is, to determine whether the push-pull member 400 is in a forward-pushing or backward-pushing state, so that the controller controls the liquid flow rate of the first water outlet and the second water outlet according to the push-pull state of the push-pull member 400, so as to reduce the residual water stains on the ground.

[0130] In some embodiments, please refer to Figure 7 As shown, a liquid collection area 230 is formed between the first cleaning component 210 and the second cleaning component 220; the floor brush body 100 is provided with a suction duct, the top of the liquid collection area 230 is connected to the suction duct, and the liquid collection area 230 is configured to be adjacent to at least one of the first cleaning component 210 and the second cleaning component 220 so that liquid dripping into the liquid collection area 230 can be absorbed by at least one of the first cleaning component 210 and the second cleaning component 220. In this way, liquid can be prevented from dripping onto the ground, thereby reducing water stains on the ground.

[0131] In some embodiments, the first cleaning element 210 and the second cleaning element 220 are both roller brushes; the central axes of the first cleaning element 210 and the second cleaning element 220 are 6-9 cm apart, that is, the center distance between the first cleaning element 210 and the second cleaning element 220 in the front-back direction is 6-9 cm; or, the outer contours of the first cleaning element 210 and the second cleaning element 220 are 0-6 mm apart, which can reduce the distance between the first cleaning element 210 and the second cleaning element 220 so as to form a liquid accumulation area 230 between the first cleaning element 210 and the second cleaning element 220; in addition, it can improve the structural compactness of the cleaning device 10, thereby reducing the volume of the cleaning device 10 and realizing the miniaturization of the cleaning device 10.

[0132] In some embodiments, the floor brush assembly further includes a first drive motor 600 and a second drive motor 700; the first drive motor 600 is connected to the first cleaning component 210 and is configured to drive the first cleaning component 210 to rotate around its own axis; the second drive motor 700 is connected to the second cleaning component 220 and is configured to drive the second cleaning component 220 to rotate around its own axis. In this way, the rotational speeds of the first cleaning component 210 and the second cleaning component 220 can be controlled independently, and the back-and-forth movement of the floor brush assembly can be achieved by the speed difference between the first cleaning component 210 and the second cleaning component 220, thereby achieving the purpose of cleaning residual water stains on the floor.

[0133] Please refer to Figure 6 As shown in the illustration, this application embodiment also provides a floor brush assembly, including a floor brush body 100 and a cleaning component 200 disposed on the floor brush body 100. The floor brush body 100 has a suction duct, and the cleaning component 200 includes a first cleaning element 210 and a second cleaning element 220 spaced apart along the front-back direction of the floor brush body 100, wherein the front-back direction is as follows: Figure 6 In the X direction, the first cleaning component 210 and the second cleaning component 220 are arranged parallel and side by side. The first cleaning component 210 and the second cleaning component 220 are rotatably connected to the floor brush body 100, and the first cleaning component 210 and the second cleaning component 220 can rotate around their own axes to clean the floor. It can be understood that by setting two cleaning components, the cleaning area of ​​the floor brush assembly can be increased, thereby improving the cleaning efficiency.

[0134] The first cleaning component 210 and the second cleaning component 220 can both be roller brushes.

[0135] In this embodiment, only the first cleaning component 210 and the second cleaning component 220 are in contact with the ground, while the other brush bodies 100 are not in contact with the ground. While cleaning the ground, the first cleaning component 210 and the second cleaning component 220 also support the brush bodies 100. This increases the pressure between the first cleaning component 210 and the second cleaning component 220 and the ground. When the brush assembly is pushed forward and pulled back, the rolling friction between the first cleaning component 210 and the second cleaning component 220 and the ground can be increased, thereby improving the cleaning effect and efficiency.

[0136] In addition, in this embodiment, the distance between the first cleaning component 210 and the second cleaning component 220 is as small as possible, as long as the first cleaning component 210 and the second cleaning component 220 do not interfere with each other when rotating around their own axes. In this way, by reducing the distance between the first cleaning component 210 and the second cleaning component 220 in the front-to-back direction, and by having the first cleaning component 210 and the second cleaning component 220 contact the ground, the overall size of the floor brush assembly can be reduced, and the structural compactness of the floor brush assembly can be improved.

[0137] In order to improve the cleaning effect of the first cleaning component 210 and the second cleaning component 220, it is usually necessary to humidify the first cleaning component 210 and the second cleaning component 220 so that the first cleaning component 210 and the second cleaning component 220 contain a certain amount of moisture, so as to perform wet mopping or wet wiping on the floor, thereby improving the cleaning effect and efficiency.

[0138] However, when the local brush assembly stops running, a water stain is easily left on the ground in the area between the first cleaning component 210 and the second cleaning component 220, which affects the user experience.

[0139] To address the aforementioned technical problems, the floor brush assembly provided in this application embodiment reduces the distance between the first cleaning component 210 and the second cleaning component 220 in the front-to-back direction, thereby forming a liquid collection area 230 between the first cleaning component 210 and the second cleaning component 220. The top of the liquid collection area 230 is connected to the suction duct 110. The liquid collection area 230 is configured to be adjacent to at least one of the first cleaning component 210 and the second cleaning component 220, so that liquid dripping into the liquid collection area 230 can be absorbed by at least one of the first cleaning component 210 and the second cleaning component 220. This reduces the problem of residual water stains on the floor when the floor brush assembly is stationary, thereby improving the user experience.

[0140] It should be noted that the first cleaning component 210 and the second cleaning component 220 may be in contact, or they may not be in contact, but the area formed between them prevents liquid from dripping onto the ground. Furthermore, the first cleaning component 210 and the second cleaning component 220 do not interfere with each other when they rotate around their own axes. The area in contact between the first cleaning component 210 and the second cleaning component 220 can form a liquid collection area 230. In this way, liquid dripping from the area above the liquid collection area 230 can be collected in the liquid collection area 230 and absorbed by at least one of the first cleaning component 210 and the second cleaning component 220, preventing liquid from dripping onto the ground and thus reducing water stains on the ground.

[0141] In some embodiments, the central axes of the first cleaning component 210 and the second cleaning component 220 are 6-9 cm apart, that is, the center distance between the first cleaning component 210 and the second cleaning component 220 in the front-back direction is 6-9 cm. For example, the center distance between the first cleaning component 210 and the second cleaning component 220 in the front-back direction is 6 cm, 7 cm, 8 cm, 9 cm, etc.; or, the outer contours of the first cleaning component 210 and the second cleaning component 220 are 0-6 mm apart. For example, the outer contours of the first cleaning component 210 and the second cleaning component 220 are 0 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, etc. This can reduce the distance between the first cleaning component 210 and the second cleaning component 220, so as to form a liquid accumulation area 230 between the first cleaning component 210 and the second cleaning component 220; in addition, it can improve the structural compactness of the cleaning device 10, thereby reducing the volume of the cleaning device 10 and realizing the miniaturization of the cleaning device 10.

[0142] In some embodiments, the floor brush assembly further includes a liquid supply assembly 300. For example, the liquid supply assembly 300 includes a liquid supply pipe and a water pump connected to the liquid supply pipe. The water pump is connected to a water source. The liquid supply pipe is connected to the first cleaning component 210 and the second cleaning component 220, respectively. In this way, the cleaning liquid pumped into the liquid supply pipe by the water pump is sprayed onto the first cleaning component 210 and the second cleaning component 220, respectively, to increase the humidity of the first cleaning component 210 and the second cleaning component 220, thereby improving the removal of stubborn stains and dust on the ground.

[0143] In some embodiments, the liquid supply assembly 300 includes a first liquid supply pipe 310 and a second liquid supply pipe 320. The first liquid supply pipe 310 is used to supply liquid to the first cleaning component 210, and the second liquid supply pipe 320 is used to supply liquid to the second cleaning component 220. That is, the first liquid supply pipe 310 and the second liquid supply pipe 320 supply liquid to the first cleaning component 210 and the second cleaning component 220 respectively, and the liquid supply flow rate of the first liquid supply pipe 310 and the second liquid supply pipe 320 is adjustable. The second liquid supply pipe 320 can supply cleaning liquid according to the needs of the second cleaning component 220. For example, when the ground brush assembly moves forward, the liquid supply flow rate of the first liquid supply pipe 310 is greater than the liquid supply flow rate of the second liquid supply pipe 320, that is, the water output of the second liquid supply pipe 320 is reduced and the water output of the first liquid supply pipe 310 is increased; when the ground brush assembly moves backward, the liquid supply flow rate of the first liquid supply pipe 310 is less than the liquid supply flow rate of the second liquid supply pipe 320, that is, the water output of the first liquid supply pipe 310 is reduced and the water output of the second liquid supply pipe 320 is increased.

[0144] In this way, when the floor brush assembly is in the forward-pushing state, the water content of the first cleaning component 210 is greater than that of the second cleaning component 220. This allows the second cleaning component 220 to absorb the water residue left on the ground by the first cleaning component 210 as it moves forward following the first cleaning component 210. Conversely, when the floor brush assembly is in the backward-pushing state, the water content of the second cleaning component 220 is greater than that of the first cleaning component 210. This allows the first cleaning component 210 to absorb the water residue left on the ground by the second cleaning component 220 as it moves backward following the second cleaning component 220. Therefore, by making the flow rate of the first liquid supply pipe 310 and the second liquid supply pipe 320 adjustable, the amount of water residue left on the ground can be reduced during the forward and backward movement of the floor brush assembly, thereby improving the user experience. In addition, it can also save cleaning liquid and extend the runtime of the cleaning liquid in the built-in water tank of the cleaning equipment.

[0145] In some embodiments, please continue to refer to Figure 6 As shown, both the first cleaning component 210 and the second cleaning component 220 are roller brushes. The first cleaning component 210 and the second cleaning component 220 can rotate around their own axes, and the first cleaning component 210 and the second cleaning component 220 rotate in opposite directions. The relative rotation of the first cleaning component 210 and the second cleaning component 220 means that when in the forward pushing state, the second cleaning component 220 can provide assistance to the first cleaning component 210; when in the backward pulling state, the first cleaning component 210 can provide assistance to the second cleaning component 220. In this way, when the user operates the floor brush assembly to clean the floor, pushing and pulling is more effortless, and no assist wheel is needed. It also avoids secondary pollution to the floor caused by the assist wheel rolling over the ground, and improves the overall structural compactness of the floor brush assembly.

[0146] In some embodiments, the floor brush assembly further includes a first drive motor 600 and a second drive motor 700; wherein, the first cleaning component 210 has a first receiving cavity inside, the second cleaning component 220 has a second receiving cavity inside, the first drive motor 600 is disposed in the first receiving cavity and connected to the first cleaning component 210 to drive the first cleaning component 210 to rotate about its own axis; the second drive motor 700 is disposed in the second receiving cavity and connected to the second cleaning component 220 to drive the second cleaning component 220 to rotate about its own axis.

[0147] It is understood that, in this embodiment of the application, by setting the first drive motor 600 inside the first cleaning component 210 and the second drive motor 700 inside the second cleaning component 220, the overall size of the floor brush assembly can be reduced, thereby improving the compactness of the overall structure of the floor brush assembly. In addition, by setting the first drive motor 600 and the second drive motor 700 respectively, the rotation speed of the first cleaning component 210 and the second cleaning component 220 can be controlled independently, which helps to push and pull, saving time and effort during operation. Moreover, the floor brush assembly can move back and forth by the speed difference between the first cleaning component 210 and the second cleaning component 220 to clean residual water stains on the ground, thereby improving the user experience.

[0148] The first drive motor 600 and the second drive motor 700 can refer to relevant technologies and are not limited here.

[0149] In some embodiments, a controller is also included. The controller is electrically connected to the first drive motor 600 and the second drive motor 700 respectively. The controller is configured to control the rotational speeds of the first drive motor 600 and the second drive motor 700 respectively. In this way, the rotational speeds of the first cleaning component 210 and the second cleaning component 220 can be controlled independently by the controller through the first drive motor 600 and the second drive motor 700 respectively, thereby achieving a degree of automation in the rotational speed regulation of the first cleaning component 210 and the second cleaning component 220.

[0150] In some embodiments, the controller can control the cleaning equipment to move back and forth in a pushing and pulling state by the first drive motor 600 and the second drive motor 700 respectively, so as to achieve the purpose of cleaning residual water stains on the ground.

[0151] For example, when the rotational speed of the first cleaning component 210 is greater than the rotational speed of the second cleaning component 220, the first cleaning component 210 rotates while the second cleaning component 220 stops rotating, and the floor brush assembly moves forward; when the rotational speed of the second cleaning component 220 is greater than the rotational speed of the first cleaning component 210, the second cleaning component 220 rotates while the first cleaning component 210 stops rotating, and the floor brush assembly moves backward. Thus, by controlling the rotational speed difference between the first cleaning component 210 and the second cleaning component 220, the reciprocating motion of the floor brush assembly is achieved, thereby achieving the purpose of cleaning residual water stains on the floor.

[0152] Alternatively, software control can be used to delay the shutdown of one of the first cleaning components 210 and the second cleaning component 220 after the entire cleaning equipment has stopped. At this time, the floor brush assembly moves forward or backward a certain distance under the drive of a single roller brush in order to wipe away the water stains remaining on the floor, thereby avoiding the problem of water stains remaining in the area between the first cleaning component 210 and the second cleaning component 220.

[0153] In some embodiments, please refer to Figure 6 and Figure 7 As shown, when the first cleaning component 210 and the second cleaning component 220 turn towards each other, a liquid suspension zone 240 is formed between the first cleaning component 210 and the second cleaning component 220 near the ground. The liquid suspension zone 240 is located below the liquid accumulation zone 230, and the liquid suspension zone 240 and the liquid accumulation zone 230 are interconnected. Under the power of the relative rotation of the first cleaning component 210 and the second cleaning component 220, the liquid in the liquid suspension zone 240 will be gathered upward in the vertical direction. In this way, part of the upwardly gathered liquid can be absorbed by the first cleaning component 210 and the second cleaning component 220, and the other part can be sucked away by the suction duct 110 located above the suspended liquid accumulation zone 230, thereby reducing the residual water stains on the ground.

[0154] In some embodiments, the floor brush body 100 is provided with a suction duct 110, which has an air inlet located directly above the liquid suspension zone 240. Under suction force, the suction duct 110 can draw at least a portion of the liquid gathered in the liquid suspension zone 240 into the suction duct 110 through the air inlet. The liquid collected in the liquid suspension zone 240, as well as dirt such as dust particles, can be drawn into the suction duct 110 through the air inlet, thereby achieving the purpose of cleaning the floor and reducing residual water stains on the floor.

[0155] The shape of the air intake includes, but is not limited to, circles, squares, polygons, etc., and is not restricted here.

[0156] Additionally, please refer to Figure 7 As shown, the suction duct 110 extends vertically upwards, and has an air inlet at the bottom. In this way, liquid and dust particles in the liquid suspension area 240 can be directly sucked into the suction duct 110, making the suction force more concentrated and preventing dirt from getting stuck at the bends of the suction duct 110. In addition, the size of the floor brush assembly in the forward and backward pushing direction is reduced, improving the compactness of the structural layout of the floor brush assembly.

[0157] In this embodiment, the suction duct 110 extends vertically. Compared to a suction duct 110 that bends to both sides, the vertically extending suction duct 110 avoids the dispersion of suction caused by the bends to both sides, resulting in more concentrated suction. It also prevents dirt from getting stuck at the bends of the suction duct 110, making it less prone to clogging. The first cleaning component 210 and the second cleaning component 220 are more convenient to self-clean. At the same time, it also reduces the overall size of the floor brush assembly, making the structure of the floor brush assembly more compact.

[0158] In some embodiments, the connection between the liquid suspension zone 240 and the liquid accumulation zone 230 is located at the minimum gap between the first cleaning member 210 and the second cleaning member 220. In this way, when the cleaning equipment 10 is stopped, the liquid accumulated in the liquid accumulation zone 230 is directly absorbed by at least one of the first cleaning member 210 and the second cleaning member 220, and will not leak through the connection between the liquid suspension zone 240 and the liquid accumulation zone 230, thereby improving the water stains remaining on the ground after the cleaning equipment 10 is stopped.

[0159] When the cleaning equipment is running, the liquid suspension zone 240 and the liquid collection zone 230 are connected at the minimum gap between the first cleaning component 210 and the second cleaning component 220 under the suction force of the suction duct 110, so that the liquid accumulated in the liquid suspension zone 240 can be sucked away by the suction duct 110 through the liquid collection zone 230.

[0160] To achieve self-cleaning of the first cleaning component 210 and the second cleaning component 220, in some embodiments, please refer to... Figures 8 to 10 As shown, the floor brush assembly also includes two scraper blades 830. Along the left-right direction of the floor brush body 100, the two scraper blades 830 are respectively disposed on opposite sides of the air intake, and both scraper blades 830 are in direct contact with the first cleaning component 210 and the second cleaning component 220. When the first cleaning component 210 and the second cleaning component 220 rotate relative to each other, the scraper blades 830 move relative to the first cleaning component 210 and the second cleaning component 220 respectively, so as to collect the dirt on the first cleaning component 210 and the second cleaning component 220 and directly suck it into the suction duct 110 through the air intake. It can be seen that the dirt on the first cleaning component 210 and the second cleaning component 220 can be scraped off by the two scraper blades 830 respectively, and the scraped dirt can be directly sucked off by the suction duct 110 through the air intake, so as to achieve self-cleaning of the first cleaning component 210 and the second cleaning component 220.

[0161] The scraper 830 is a long strip structure that extends along the length of the first cleaning member 210 and the second cleaning member 220. This increases the scraping area of ​​the scraper 830, thereby improving the self-cleaning area of ​​the first cleaning member 210 and the second cleaning member 220.

[0162] In some embodiments, along the extending direction of the vertical scraper 830, each scraper 830 has a first scraper portion 831 and a second scraper portion 832 respectively disposed on opposite sides. The first scraper portion 831 is in interference contact with the first cleaning member 210, and the second scraper portion 832 is in interference contact with the second cleaning member 220. A liquid collection area 833 that can accommodate dirt is formed between the oppositely disposed first scraper portion 831 and second scraper portion 832. The liquid collection area 833 is located above the liquid collection area 230 and is connected to the air intake.

[0163] Thus, when the first cleaning component 210 rotates relative to the first scraper portion 831, the first scraper portion 831 scrapes off the dirt on the first cleaning component 210, and the scraped dirt is accumulated in the liquid collection area 833; when the second cleaning component 220 rotates relative to the second scraper portion 832, the second scraper portion 832 scrapes off the dirt on the second cleaning component 220, and the scraped dirt is accumulated in the liquid collection area 833, and the dirt in the liquid collection area 833 is sucked away by the suction duct 110 through the air inlet, preventing dirt from dripping onto the ground, thereby improving the self-cleaning effect of the first cleaning component 210 and the second cleaning component 220.

[0164] It is understandable that by setting the liquid collection area 833 above the liquid collection area 230, the liquid collection area 833 is closer to the air intake, so that the dirt accumulated in the liquid collection area 833 can be sucked out by the suction duct 110 more efficiently.

[0165] It should be noted that the liquid collection zone 230 is mainly used to collect liquid dripping from the top of the floor brush assembly when the cleaning equipment 10 is stopped; while the liquid suspension zone 240 is mainly used to collect liquid from the first cleaning component 210, the second cleaning component 220, and the ground when the cleaning equipment 10 is working, under the suction force of the suction duct, the liquid can be collected in the liquid suspension zone 240. In this way, the liquid collected in the liquid suspension zone 240 is sucked away by the suction duct 110 through the liquid collection zone 230, thereby avoiding the problem of residual water stains on the ground; the liquid collection zone is mainly used to collect the liquid from the first cleaning component 210 and the second cleaning component 220 during self-cleaning. The first cleaning component 210 and the second cleaning component 220 are used to collect dirt, and the collection area 833 is positioned above the collection area 230 to reduce the distance between the collection area 833 and the air intake. This allows the dirt in the collection area 833 to be quickly drawn into the air intake duct 110 through the air intake, thus achieving the purpose of quickly removing dirt. In addition, it can prevent the liquid in the collection area 833 from dripping onto the ground and causing water stains on the ground. If there is any overflow in the collection area 833, it can also accumulate in the collection area 230 below and be absorbed by at least one of the first cleaning component 210 and the second cleaning component 220. In this way, the first cleaning component 210 and the second cleaning component 220 can remove dirt again during self-cleaning.

[0166] To further improve the self-cleaning capabilities of the first cleaning component 210 and the second cleaning component 220, in some embodiments, please refer to... Figures 8 to 10As shown, the first scraper section 831 and the second scraper section 832, which are arranged opposite to each other, are inclined towards the side that is far away from each other. That is to say, in the front-back direction, the middle of the first scraper section 831 and the second scraper section 832 are closer to the air intake than the two ends. In this way, the middle of the liquid collection area 833 is higher than the surrounding area, and the air intake is located in the middle area of ​​the liquid collection area 833. This can increase the volume of the liquid collection area 833, as well as increase the contact area between the first scraper section 831 and the first cleaning member 210, and increase the contact area between the second scraper section 832 and the second cleaning member 220, thereby improving the ability of the first scraper section 831 and the second scraper section 832 to remove dirt.

[0167] In addition, such as Figure 10 As shown, the first scraper portion 831 and the second scraper portion 832 extend in a spiral shape, that is, along the extension direction of the scraper 830, the extension direction of the first scraper portion 831 is spiral relative to the extension direction of the first cleaning member 210; along the extension direction of the second scraper portion 832, the extension direction of the second scraper portion 832 is spiral relative to the extension direction of the second cleaning member 220. In this way, the first scraper portion 831 is spirally wound around a part of the structure of the first cleaning member 210, and the second scraper portion 832 is spirally wound around a part of the structure of the second cleaning member 220, which can further improve the ability of the first scraper portion 831 and the second scraper portion 832 to remove dirt and the area of ​​dirt removed, thereby improving the self-cleaning ability and efficiency of the first cleaning member 210 and the second cleaning member 220.

[0168] In some embodiments, the floor brush assembly further includes a liquid supply line, one end of which is connected to a water source and the other end of which is connected to the roller brush assembly, to provide cleaning liquid to the first cleaning component 210 and the second cleaning component 220 respectively, so as to humidify the first cleaning component 210 and the second cleaning component 220, increase the moisture content of the first cleaning component 210 and the second cleaning component 220, thereby improving the cleaning effect and efficiency.

[0169] In some embodiments, please refer to Figure 9 and Figure 10As shown, the floor brush assembly also includes a water distributor 800, which includes a first water distributor 810 and a second water distributor 820. The first water distributor 810 is disposed above the first cleaning component 210 and extends along the length of the first cleaning component; the second water distributor 820 is disposed above the second cleaning component 220 and extends along the length of the second cleaning component; a scraper 830 is disposed between the first water distributor 810, the first cleaning component 210, and the second cleaning component 220; the first water distributor 810 has a plurality of first drain holes, which are spaced apart along the length of the first cleaning component; the second water distributor 820 has a plurality of second drain holes, which are spaced apart along the length of the second cleaning component; a liquid supply pipe is connected to the first water distributor 810 and the second water distributor 820 respectively, so that the liquid supplied by the liquid supply pipe is sprayed onto the first cleaning component 210 and the second cleaning component 220 through the first water distributor 810 and the second water distributor 820 respectively.

[0170] It is understandable that by setting up a first water distributor 810 and a second water distributor 820, and by setting multiple first drain holes spaced vertically on the first water distributor 810 and multiple second drain holes spaced vertically on the second water distributor 820, the uniformity of the cleaning liquid sprayed onto the first cleaning component 210 and the second cleaning component 220 can be improved, thereby improving the uniformity of the water content of the first cleaning component 210 and the second cleaning component 220, and thus improving the cleaning effect on the ground.

[0171] In some embodiments, such as Figure 9 and Figure 10 As shown, the water distributor 800 and the scraper 830 can be formed into a single structure through an integral molding process such as injection molding or casting. This can improve the compactness of the structure, reduce the installation process, and lower the process cost.

[0172] In addition, the first cleaning component 210 and the second cleaning component 220 are detachably connected to the floor brush body 100, that is, the first cleaning component 210 and the second cleaning component 220 can be disassembled separately. In this way, the first cleaning component 210 and the second cleaning component 220 can be disassembled, maintained, or replaced separately, thereby improving the user experience.

[0173] Both the first cleaning component 210 and the second cleaning component 220 can be disassembled from both ends of the brush body 100. For example, both ends of the brush body 100 have detachable end caps. When it is necessary to disassemble at least one of the first cleaning component 210 and the second cleaning component 220, the end caps can be opened to achieve disassembly. The end caps and the brush body 100 can be detachably connected by means of snap-fit ​​or other methods, which is not limited here.

[0174] This application embodiment also provides a cleaning device, including a floor brush assembly and a body assembly as provided in the above embodiments. One end of the body assembly can be gripped by a person, and the other end is rotatably connected to the floor brush assembly. A push-pull member 400 is provided at the end of the body assembly connected to the floor brush assembly. The push-pull member 400 is movably connected to the floor brush body 100 and can move back and forth relative to the floor brush body 100. Along the back and forth direction of the floor brush body 100, the push-pull member 400 is located at the first liquid supply pipe 310 and... Between the second liquid supply pipe 320; when the push-pull member 400 moves the floor brush assembly forward under the action of external force, the push-pull member 400 squeezes the second liquid supply pipe 320 so that the liquid supply flow rate of the second liquid supply pipe 320 is less than the liquid supply flow rate of the first liquid supply pipe 310; when the push-pull member 400 moves the floor brush assembly backward under the action of external force, the push-pull member 400 squeezes the first liquid supply pipe 310 so that the liquid supply flow rate of the first liquid supply pipe 310 is less than the liquid supply flow rate of the second liquid supply pipe 320.

[0175] In this way, when the floor brush assembly is in the forward-pushing state, the water content of the first cleaning component 210 is greater than that of the second cleaning component 220. This allows the second cleaning component 220 to absorb the water residue left on the ground by the first cleaning component 210 as it moves forward following the first cleaning component 210. Conversely, when the floor brush assembly is in the backward-pushing state, the water content of the second cleaning component 220 is greater than that of the first cleaning component 210. This allows the first cleaning component 210 to absorb the water residue left on the ground by the second cleaning component 220 as it moves backward following the second cleaning component 220. Therefore, by making the flow rate of the first liquid supply pipe 310 and the second liquid supply pipe 320 adjustable, the amount of water residue left on the ground can be reduced during the forward and backward movement of the floor brush assembly, thereby improving the user experience. In addition, it can also save cleaning liquid and extend the runtime of the cleaning liquid in the built-in water tank of the cleaning equipment.
