[0004] In current cleaning equipment, such as floor scrubbers, users need to discharge the sewage in the sewage tank of the floor scrubber after cleaning. The sewage in the sewage tank often contains some debris such as hair, and users need to remove the sewage tank and pour out the sewage in the sewage tank, which also requires manual intervention, making the cleaning operation inconvenient; if the sewage outlet of the sewage tank relies on gravity to make the sewage flow out naturally, it is easy to cause the sewage tank to discharge slowly and be easily blocked, making it inconvenient to self-clean the sewage tank and the sewage cleaning effect poor. Utility Model Content

[0005] The embodiments of the present application provide a cleaning system that can optimize the sewage cleaning effect of the sewage tank and improve the self-cleaning effect of the sewage tank. At the same time, the sewage cleaning operation process of the present application has a high degree of automation, which saves time and effort and helps to improve user experience.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] In a first aspect, an embodiment of the present application provides a cleaning system, which includes a cleaning device, wherein the cleaning device includes a sewage tank and a fan, wherein the sewage tank is provided with a sewage outlet and a switch valve, wherein the switch valve is configured to control the opening or closing of the sewage outlet, and the switch state of the switch valve is linked to the operating state of the fan; the output port of the fan is configured to be connected to the sewage tank, and when the fan is running, wind pressure is generated to pressurize the sewage in the sewage tank, and when the switch valve is in the open state, the sewage is discharged through the sewage outlet.

[0008] This helps to quickly discharge the sewage in the sewage tank through the sewage outlet, thereby reducing the residual stains in the sewage tank and maximizing the sewage cleaning effect of the sewage tank. In addition, the sewage cleaning operation process of the present application has a high degree of automation, which saves time and effort and helps improve user experience.

[0009] In a possible implementation, the switch valve is an electric control valve or a solenoid valve; when the fan starts to run, the switch valve opens synchronously; or, after the fan runs to form wind pressure and pressurizes the sewage in the sewage tank for a preset time, the switch valve opens; or, after the switch valve opens and the sewage is discharged through the sewage outlet for a preset time, the fan starts to run. Among them, the implementation form of the electric control valve can be achieved by using an ordinary small motor to drive the valve to rotate using a reduction box to achieve opening and closing.

[0010] In this way, when the fan and the switch valve are opened synchronously, the sewage discharge will not be interrupted, which is beneficial to improving the sewage discharge efficiency and saving sewage discharge time. When the fan is turned on first and then the switch valve is opened, the wind pressure of the fan reaches the sewage tank continuously, and the pressure on the sewage reaches the maximum, so that when the switch valve is opened, the sewage discharge speed can reach the maximum, improving the sewage discharge effect. When the switch valve is opened first and then the fan is started, it is beneficial to discharge the solid garbage that is difficult to discharge remaining in the sewage tank, thereby achieving energy saving. The linkage mode of the fan and the switch valve can be achieved by outputting a high / low level when the fan is running to trigger the switch of the switch valve, or by uniformly outputting a set of corresponding instructions through the control circuit to control the state of the fan and the switch valve. It should be noted that the situation involving switch linkage in the following embodiments can also be implemented in the above manner, which can be achieved only through circuit design without involving program control.

In this way, when the fan is pressurized, it is helpful to reduce the air filling and pressure relief of the fan, thereby avoiding the backflow of sewage; when the main motor is sucking, it is avoided that the sewage is directly sucked into the main motor, reducing the risk of water corrosion of the main motor.

[0017] In a possible implementation, the sewage inlet of the sewage tank is provided with a sewage inlet check valve, and external sewage flows into the sewage tank through the sewage inlet check valve, which is helpful to prevent the sewage from flowing in the opposite direction, thereby avoiding the backflow of sewage.

In this way, the wind pressure when the fan is running is transmitted from the fan through the floor brush assembly to the inside of the sewage tank, pressurizing the sewage in the sewage tank. At the same time, the opening or closing of the first valve makes the process of pressurizing the sewage in the sewage tank by the fan and the process of sucking the external sewage by the main motor two separate processes, and the pressurization process and the sewage suction process do not interfere with each other.

[0024] In a possible implementation, the first valve is arranged at the three-way assembly, and the first valve has a rotatable seal. When the first valve is in an open state, the first inlet is open, and the second inlet is blocked and closed by the seal; when the first valve is in a closed state, the first inlet is blocked and closed by the seal, and the second inlet is open. In this way, the on-off linkage control of the first inlet and the second inlet can be realized quickly and conveniently.

When the fan is running, the second valve is in a closed state; when the main motor is running, the second valve is in an open state. In this way, the opening or closing of the second valve can also ensure that the pressurization process and the sewage suction process do not interfere with each other.

[0026] In a possible implementation, the first valve and / or the second valve is one of an electric control valve, a one-way valve and a solenoid valve.

[0031] In this way, the auxiliary sewage tank can be used as a transfer location after the sewage in the sewage tank is pumped out, which helps to extend the cleaning time of the sewage in the sewage tank. In addition, the auxiliary sewage tank can separate the solid waste and sewage in the sewage tank to achieve the solid-liquid separation function without the need to set up a separate solid-liquid separation device.

[0040] In a possible implementation, a sewage inlet pipe is provided in the cleaning device, and the inlet of the sewage inlet pipe is located in the cavity of the sewage tank. In this way, the sewage on the surface to be cleaned is sucked back into the cavity of the sewage tank through the sewage inlet pipe.

[0041] In a possible implementation, a one-way valve is provided at the inlet of the sewage inlet pipe, and the one-way valve has an open state and a closed state. When the sewage inlet pipe is inflowing water, the one-way valve is in the open state, and when the sewage inlet pipe stops inflowing water, the one-way valve is in the closed state.

[0042] In this way, the floor brush assembly and the sewage inlet pipe can be opened or closed, so that the air duct is open when the cleaning equipment is working normally, and the air duct is sealed when the cleaning equipment is shut down or the auxiliary drainage box is used for auxiliary drainage; in addition, when the one-way valve is in a closed state, it helps to prevent the sewage in the sewage tank from flowing back from the sewage inlet pipe to the floor brush assembly.

In this way, it is helpful to realize the opening or closing of the floor brush assembly and the sewage inlet pipe.

[0047] In the second aspect, an embodiment of the present application provides a cleaning system, including a cleaning body, on which a main motor and a sewage tank are provided, the main motor is connected to the sewage tank, and the sewage tank has a sewage inlet and a sewage outlet; when the cleaning body is in a pressurized sewage discharge mode, the sewage outlet is in an open state and the main motor is turned off, and under the action of external force, gas enters the sewage tank through the sewage inlet to achieve positive pressure, and controls the sewage in the sewage tank to be discharged through the sewage outlet.

[0048] The above solution can effectively achieve better self-cleaning of the sewage tank. Specifically, when cleaning equipment, such as a floor scrubber, is cleaning, it will suck dirt into the sewage tank, including some hair, etc., and the dirt is easy to stick to the sewage tank. It is very troublesome to clean the sewage tank. In this case, pressure is applied to the sewage tank when the sewage tank is discharged, so that the dirt is pressed out by a larger pressure. Therefore, under positive pressure, the dirt is more easily discharged.

[0049] In a conceivable scenario, the inner wall of the sewage tank is stuck with hair and other dirt. Due to the positive pressure in the sewage tank, the pressure is greater when the sewage is discharged, which can easily wash the inner wall surface, thereby taking away the hair and other dirt. In another scenario, since the pressurization is carried out by gas, even if the water in the sewage tank cannot cover the stuck hair, the high-pressure gas will blow the above-mentioned hair, thereby taking away the above-mentioned dirt.

[0050] Based on this, it can be seen that compared with the existing technology, this solution can better realize the self-cleaning of the sewage tank, with better effect, and at the same time it can target more scenarios, making the cleaning of the sewage tank more convenient.

[0051] In one possible implementation, the cleaning body is provided with a floor brush, a floor brush hose is provided inside the floor brush, and the floor brush hose is connected to the sewage inlet. When the cleaning body is in a pressurized sewage discharge mode, under the action of external force, gas enters the sewage inlet through the floor brush hose and pressurizes the sewage tank.

[0052] The above scheme introduces a method of increasing pressure from the floor brush, and using the floor brush hose can achieve better results by making the smallest possible changes to the cleaning equipment. Specifically, current cleaning equipment such as floor scrubbers have a floor brush hose for sucking dirt on their floor brushes, and the floor brush hose is connected to a sewage tank, so that during the cleaning process, the dirt can be sucked into the sewage tank using the floor brush hose.

[0053] In the above-mentioned pressurized sewage discharge, in order to achieve connectivity with the sewage tank, the floor brush hose is cleverly and directly utilized, and there is no need to add other air inlets to achieve the above-mentioned effect. This not only ensures the pressurized effect, but also prevents major modifications to the existing cleaning equipment, thereby increasing costs.

[0057] In this way, when the cleaning body is in the non-pressurized sewage discharge mode, the main body air outlet can be blocked, which is beneficial to ensure the sealing of the cleaning body, improve the sealing effect of the cleaning body, and effectively prevent the cleaning body from being easily damaged by water, thereby ensuring the normal operation of the cleaning body and extending the service life of the cleaning body; when the cleaning body is installed on the base station and is in the pressurized sewage discharge mode, the main body air outlet is connected and communicated with the base station air outlet, so that the wind pressure formed by the operation of the base station motor will pass the gas into the sewage tank through the base station air outlet, the main body air outlet and the sewage inlet of the sewage tank in turn.

[0058] In a possible implementation, it also includes a switch valve, which is arranged at the sewage outlet of the sewage tank and is configured to control the opening or closing of the sewage outlet; when the cleaning body is in the pressurized sewage discharge mode, the switch valve is in an open state.

[0059] In this way, the setting of the switching valve makes the sewage cleaning operation process of the present application more automated, saves time and effort, and helps to improve user experience.

[0060] In a possible implementation, an air outlet valve is provided at the air outlet of the base station, and the air outlet valve is used to open or close the air outlet of the base station; when the cleaning body is in a pressurized sewage discharge mode, the air outlet valve is in an open state.

[0061] In this way, when the base station is in the non-pressurized sewage discharge mode, the air outlet of the base station can be blocked by the air outlet valve, which is beneficial to ensure the sealing of the base station and improve the sealing effect of the base station. When the cleaning body is in the pressurized sewage discharge mode, the air outlet valve is opened.

[0068] In this way, when the base station motor is in a non-working state, the air duct drain port is in an open state. If water or other impurities enter the base station air duct from the base station air port, they will first flow out through the air duct drain port, which is beneficial to avoid the problem of water or other impurities entering the base station motor and damaging the base station motor, thereby ensuring the normal operation of the base station motor and extending the service life of the base station motor. When the cleaning body is in the pressurized sewage discharge mode, the air duct valve opens under the wind pressure of the base station motor, and the air duct valve blocks the air duct drain port, thereby forming a sealed state of the air duct drain port, which helps to reduce wind loss in the base station air duct and ensure the normal flow of gas, thereby ensuring that there is a strong enough wind force to enter the sewage tank.

[0069] In a possible implementation, the air duct valve includes an air duct valve body, an air duct switch part and an air duct elastic part, the air duct valve body is connected to the inner wall of the base station air duct, and the air duct switch part is connected to the air duct valve body through the air duct elastic part; the air duct switch part blocks the base station air duct under the action of the air duct elastic part; when the cleaning body is in the pressurized sewage discharge mode, the air duct switch part opens under the action of the wind pressure of the base station motor.

[0074] This helps save space for installing a water replenishment device in the base station, thereby reducing the size of the base station and achieving the function of replenishing water without a clean water tank. At the same time, it can achieve large-volume cleaning of the cleaning body and replenishment of the sewage tank, improving the self-cleaning effect of the cleaning body and the sewage tank.

[0075] In a possible implementation, the base station has a main body mounting surface, which is used to install the cleaning body; the water outlet ends of the first water outlet pipe and the second water outlet pipe are arranged on the main body mounting surface at intervals; when the cleaning body is installed on the base station, the water outlet ends of the first water outlet pipe and the water outlet ends of the second water outlet pipe are respectively located on opposite sides of the cleaning body.

[0076] This helps to achieve a large amount of water spraying on the floor brush, thereby achieving a large amount of water cleaning of the cleaning body and water replenishment of the sewage tank, thereby improving the self-cleaning effect of the sewage tank and the cleaning body.

[0077] In a possible implementation, the directions of the water outlet end of the first water outlet pipe and the water outlet end of the second water outlet pipe are both inclined upward relative to the main body installation surface.

[0078] In this way, the water spraying direction is all toward the cleaning body, thereby further ensuring a large amount of water cleaning of the cleaning body and water replenishment of the sewage tank, thereby improving the self-cleaning effect of the sewage tank and the cleaning body.

[0079] In a possible implementation, an angle between the orientation of the water outlet end of the first water outlet pipe and the orientation of the water outlet end of the second water outlet pipe and the main body installation surface is greater than 0° and less than 90°.

[0080] In this way, the water spraying direction is all toward the cleaning body, thereby further ensuring a large amount of water cleaning of the cleaning body and water replenishment of the sewage tank, thereby improving the self-cleaning effect of the sewage tank and the cleaning body.

[0081] In a possible implementation, the base station has a main body installation surface, and the main body installation surface is used to install the cleaning body; the main body installation surface is provided with an overflow detection member and an overflow port.

[0082] In this way, the overflow detection member is set to detect the water level in the main body installation surface, and when the water level is higher than the set height, an audible and visual signal can be issued to remind the user to deal with it in time. When the overflow detection fails, the accumulated water can flow into the overflow port, thereby effectively preventing the overflow detection from failing or preventing the overflow detection from being untimely when there is a large amount of water.

[0083] In a third aspect, an embodiment of the present application provides a cleaning system, which includes a cleaning device. Thus, the structural parts of the cleaning device, such as the main motor, can be disassembled and used in conjunction with external auxiliary accessories, such as a remote controller; or, the main motor can be disassembled and combined with an external dust collection kit to form a complete handheld vacuum cleaner, achieving multiple uses of one machine.

[0084] The cleaning system provided in the embodiment of the present application comprises a cleaning device, and the cleaning device comprises a fan and a sewage tank. When the fan is in operation, wind pressure is formed to pressurize the sewage in the sewage tank, thereby helping to quickly discharge the sewage in the sewage tank through the sewage outlet, which is beneficial to reduce the residual stains in the sewage tank, maximize the sewage cleaning effect of the sewage tank, and improve the self-cleaning effect of the sewage tank. In addition, the sewage cleaning operation process of the present application has a high degree of automation, which saves time and effort, and helps to improve user experience. In addition, by means of pressurization, pressure is applied to the sewage tank when the sewage tank is discharging sewage, so that the above-mentioned dirt is pressed out by a larger pressure. For this reason, under the condition of positive pressure, the above-mentioned dirt is more easily discharged, which further helps to improve the cleaning effect of the sewage tank and improve the self-cleaning effect of the sewage tank and the cleaning device.

[0174] A floor scrubber is a device used to clean the floor. The working principle of a floor scrubber is as follows: the high-speed operation of the motor drives the high-speed rotation of the floor brush, while the clean water tank operates, spraying clean water forward through the water channel onto the floor brush, and coordinating with the height rotation of the floor brush, through the vacuum suction channel located behind the floor brush, and backward through another water channel, the sewage is sucked into the sewage tank, thereby completing the cleaning process.

[0175] The sewage tank is an important part of the floor scrubber. In the current floor scrubbers, after the user finishes cleaning, the sewage in the sewage tank of the floor scrubber needs to be discharged. In the related art, the sewage in the sewage tank often contains some hair and other debris. The user needs to remove the sewage tank and pour out the sewage in the sewage tank, and manual intervention is required, which is inconvenient to clean. If the sewage outlet of the sewage tank relies on gravity to make the sewage flow out naturally, it is easy to cause the sewage tank to discharge slowly and easily clogged, and the sewage cleaning effect is poor.

[0176] Based on the above technical problems, an embodiment of the present application provides a cleaning system, the cleaning system includes a cleaning device, and the cleaning device includes a fan. When the fan is in operation, wind pressure is formed to pressurize the sewage in the sewage tank, thereby helping to quickly discharge the sewage in the sewage tank through the sewage outlet, which is beneficial to reduce the residual stains in the sewage tank and maximize the sewage cleaning effect of the sewage tank. In addition, the sewage cleaning operation process of the present application has a high degree of automation, which saves time and effort and helps to improve user experience. In addition, an embodiment of the present application also provides a cleaning system, which applies pressure to the sewage tank when the sewage tank is discharging sewage by pressurization, so as to press out the above-mentioned dirt by greater pressure. For this reason, under positive pressure, the above-mentioned dirt is more easily discharged, which further helps to improve the cleaning effect of the sewage tank and improve the self-cleaning effect of the sewage tank and the cleaning equipment.

[0177] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0178] An embodiment of the present application provides a cleaning system, which may include a cleaning device 200 .

[0179] In some embodiments, the cleaning system can be used in conjunction with external structural parts. For example, after the structural parts in the cleaning device 200, such as the main motor, are removed, they can be used in conjunction with external auxiliary accessories such as a remote control, and the remote control can be used to conveniently operate and control the main motor. Alternatively, after the main motor is removed, it can be combined with an external dust collection kit to form a complete handheld vacuum cleaner, realizing multiple uses of one machine.

[0180] In some embodiments, the cleaning system can also be electrically connected to an external power supply component. For example, the power supply component can be electrically connected to the cleaning body 100 in the cleaning device 200. When the cleaning device 200 is in a self-cleaning state, the power supply component and the cleaning body 100 are in an electrically conductive state, and the electric energy of the power supply component is continuously transmitted to the cleaning body 100 to increase the electric energy required for self-cleaning of the cleaning body 100.

[0181] Reference Figure 1 As shown, an embodiment of the present application provides a cleaning device 200 , which may include a cleaning body 100 and a base station 210 .

[0182] In some embodiments, the cleaning body 100 may be a floor scrubber, such as a fully automatic floor scrubber, a semi-automatic floor scrubber, a hand-push floor scrubber, a ride-on floor scrubber, etc. In some embodiments, the cleaning body 100 may be a vacuum cleaner or a sweeping robot with a floor scrubbing function, etc. In the embodiments of the present application, the floor scrubber is mainly used as an example of the cleaning body 100 for description.

[0183] The difference between the cleaning body 100 and the base station 210 is described below.

[0184] The functions of the cleaning body 100 and the base station 210 are different: the cleaning body 100 is a cleaning mechanical device, which is mainly used to clean stains and dust on the surface to be cleaned. The surface to be cleaned can be a wooden floor, a tile floor, a marble floor, or a wall. The surface to be cleaned can also be a floor, a wall, a knitted surface, or a surface of an object to be cleaned with different degrees of roughness. The present application does not specifically limit the type of surface to be cleaned. The base station 210 is an intelligent infrastructure. When the cleaning body 100 is placed on the base station 210, the cleaning body 100 can be self-cleaned, dried, charged, and other operations.

[0185] In some embodiments, reference Figure 1 As shown, the cleaning body 100 may be provided with a rod body 180 , and the rod body 180 may be provided with a handle 181 . The user controls the running direction of the cleaning body 100 by holding the handle 181 and the rod body 180 .

[0186] The normal working mode of the cleaning body 100 provided in the embodiment of the present application is:

[0187] A clean water tank 160 is provided in the cleaning body 100, and a clean water motor is connected to the clean water tank 160. A first connecting pipe and a second connecting pipe are respectively provided between the clean water tank 160, the sewage tank 130 and the floor brush assembly 140. When the user uses the cleaning body 100 to clean the surface to be cleaned, the clean water motor is started, and the clean water motor drives the clean water in the clean water tank 160 to be transported to the floor brush assembly 140 or the surface to be cleaned through the first connecting pipe, and the floor brush assembly 140 moves on the surface to be cleaned to clean the surface to be cleaned. After the floor brush assembly 140 finishes cleaning the surface to be cleaned, the main motor 110 is started, and the sewage on the floor brush assembly 140 or the surface to be cleaned is sucked into the sewage tank 130 through the second connecting pipe connected to the main motor 110, and finally the sewage in the sewage tank 130 is discharged to the outside.

[0188] It should be noted that the clean water tank 160 is connected to the floor brush assembly 140 through the first connecting pipe, and the clean water motor drives the clean water in the clean water tank 160 to be transported to the floor brush assembly 140 or the surface to be cleaned through the first connecting pipe, and the flow direction of the clean water in the first connecting pipe is unidirectional flow. The sewage tank 130 is connected to the floor brush assembly 140 through the second connecting pipe, and the main motor 110 sucks the sewage or stains on the floor brush assembly 140 or the surface to be cleaned into the sewage tank 130 through the second connecting pipe, and the flow direction of the sewage in the second connecting pipe is also unidirectional flow.

[0189] The structure of the cleaning device provided in the embodiment of the present application is described below.

[0190] Reference Figure 1 As shown, the cleaning device 200 may include a sewage tank 130 and a fan 120. The sewage tank 130 may be provided with a sewage outlet 133. The output port of the fan 120 is connected to the sewage tank 130. When the fan 120 is running, wind pressure is generated to pressurize the sewage in the sewage tank 130, and the sewage is discharged through the sewage outlet 133.

[0191] In some embodiments, the output port of the fan 120 is connected to the sewage tank 130, which may include: Figure 2 As shown, the top of the sewage tank 130 is provided with an air inlet 131, and the fan 120 is connected to the sewage tank 130 through the air inlet 131. Fig. 9 As shown, a sewage tank 130 has a sewage inlet 132 at its bottom, and the fan 120 is connected to the sewage tank 130 through the sewage inlet 132. This embodiment does not limit this.

[0192] In some embodiments, the cleaning device 200 may include only the cleaning body 100. When the cleaning body 100 is the above-mentioned cleaning device 200, the fan 120 is disposed in the fuselage body 190. In some embodiments, the cleaning device 200 may include the cleaning body 100 and the base station 210. When the cleaning body 100 and the base station 210 are used together as the above-mentioned cleaning device 200, the fan 120 may be disposed in the base station 210. This embodiment does not limit this.

[0193] In some embodiments, the sewage tank 130 is disposed in the cleaning body 100, and the sewage outlet 133 is opened at the bottom of the sewage tank 130, wherein the opening shape and opening number of the sewage outlet 133 are not further limited. Exemplarily, the shape of the sewage outlet 133 can be circular, square, etc. Exemplarily, the sewage outlet 133 can be arranged at the bottom of the sewage tank 130 in a vertical direction, so as to facilitate the sewage to be discharged more quickly and thoroughly with the assistance of gravity.

[0194] In some embodiments, there is no further limitation on the shape and material of the sewage tank 130. For example, the sewage tank 130 may be made of silver ion antibacterial material, which can effectively achieve the purpose of inactivating and inhibiting the growth of bacteria, and prevent the sewage tank 130 from generating odor due to bacterial growth.

[0195] In some embodiments, reference Figure 1 As shown, the sewage outlet 133 may be provided with a switch valve 136, and the switch valve 136 controls the opening or closing of the sewage outlet 133. Exemplarily, this embodiment may include a controller, and the switch valve 136 is electrically connected to the controller. Exemplarily, the switch valve 136 and the controller may be electrically connected in a wired or wireless manner, and the controller controls the opening or closing of the switch valve 136, thereby realizing the opening or closing of the sewage outlet 133.

[0196] For example, the switch valve 136 of this embodiment can be an electrically controlled valve or a solenoid valve, wherein the electrically controlled valve can be realized by using an ordinary small motor to drive the valve to rotate using a reduction gear box to achieve opening and closing, which is not limited in this embodiment.

[0197] In some embodiments, the switch valve 136 and the fan 120 can be set to be turned on in linkage, wherein the linkage turns on means that the switch valve 136 and the fan 120 affect each other through certain logic and methods. The linkage mode of the fan 120 and the switch valve 136 can be achieved by outputting a high / low level when the fan 120 is running to trigger the switch of the electric control valve, or by uniformly outputting a set of corresponding instructions by the control circuit to control the state of the fan 120 and the electric control valve. It should be noted that the situation involving the switch linkage in the following embodiments can also be realized in the above manner, which can be realized only by circuit design without involving program control.

[0198] In some embodiments, the opening sequence of the fan 120 and the switch valve 136 is not further limited. Exemplarily, the fan 120 and the switch valve 136 can be opened synchronously, that is, the sewage is discharged while pressurizing, so that the sewage discharge process will not be interrupted, which is beneficial to improving the sewage discharge efficiency and ensuring the sewage discharge effect. Exemplarily, after the fan 120 operates to form wind pressure and pressurizes the sewage in the sewage tank 130 for a preset time, the switch valve 136 is opened, that is, pressurizing first and then discharging sewage. The wind pressure of the fan 120 continuously reaches the sewage tank 130, and the pressure on the sewage reaches the maximum. Therefore, when the switch valve 136 is opened, the sewage discharge speed can reach the maximum, which is beneficial to improving the sewage discharge effect. This embodiment does not limit the preset time. Exemplarily, after the switch valve 136 is opened and the sewage is discharged through the sewage outlet 133 for a preset time, the fan 120 starts to operate, that is, the sewage is discharged first and then pressurized, so that a part of the sewage can be discharged first. When the sewage is discharged to a certain extent, the fan 120 is turned on again, which is beneficial to discharge the solid waste that is difficult to discharge remaining in the sewage tank 130, thereby helping to achieve the energy saving effect of the fan 120. This embodiment does not limit the preset time.

[0199] In some embodiments, a water level sensor may be provided in the sewage tank 130, and the water level sensor is electrically connected to the controller. When the water level sensor detects that the water level of the sewage is higher than a preset liquid level, the controller controls the switch valve 136 to open, and the sewage is discharged through the sewage outlet 133, which is beneficial to avoid the problem of odor in the sewage tank 130 when the sewage in the sewage tank 130 is left for a long time, which affects the user experience. Exemplarily, the water level sensor may be a water level detection float.

[0200] The sewage discharge mode of the cleaning device 200 provided in the embodiment of the present application is:

[0201] When the water level sensor detects that the sewage in the sewage tank 130 reaches the preset water level, the water level sensor sends a sewage water level signal to the controller, and the controller sends a reminder signal to the prompt member set on the cleaning device 200 whether to discharge sewage. For example, the prompt member can be a display screen, a display light or a sounder set on the cleaning device 200, and the reminder signal can be a sound signal or a light signal of different colors. In other embodiments, the user can also send a sewage discharge instruction to the controller through an input member set on the cleaning device 200. At this time, the sewage in the sewage tank 130 can reach the preset water level or not. The input member can be a touch screen, a knob or a button. When the sewage discharge instruction is started, the sewage in the sewage tank 130 is discharged. The controller controls the fan 120 to open and the switch valve 136 to open. When the fan 120 is running, wind pressure is formed. The fan 120 drives the wind flow to pressurize the sewage in the sewage tank 130, and the pressure in the sewage tank 130 increases. Therefore, under the action of pressure, the sewage in the sewage tank 130 is discharged to the outside through the sewage outlet 133.

[0202] For example, the outside here can be a sewer in the external atmospheric environment. For example, the sewage outlet 133 can be connected to the outside through the sewage pipe 134, so that the sewage is discharged to the outside through the sewage outlet 133 and the sewage pipe 134 in sequence, which is not limited in this embodiment. It should be noted that the sewage pipe 134 is a one-way pipeline, which helps to prevent the discharged sewage from flowing back into the sewage tank 130, and further effectively ensures the smooth discharge of sewage.

[0203] Therefore, the cleaning device 200 provided in the embodiment of the present application includes a fan 120, and the fan 120 can pressurize the sewage tank 130, thereby helping to quickly discharge the sewage in the sewage tank 130 through the sewage outlet 133, which is beneficial to reduce the residual stains in the sewage tank 130 and maximize the sewage cleaning effect of the sewage tank 130; in addition, the sewage cleaning operation process of the present application has a high degree of automation, which saves time and effort, and helps to improve user experience.

[0204] In order to improve and optimize the pressurized sewage discharge effect of the sewage tank 130, in a possible implementation method, refer to Figure 2 As shown, an air inlet 131 is provided at the top of the sewage tank 130, and the fan 120 is connected to the sewage tank 130 through the air inlet 131. The air inlet 131 of the sewage tank and the sewage outlet 133 of the sewage tank can be staggered up and down along the height direction of the sewage tank 130. Exemplarily, the sewage outlet 133 of the sewage tank is located at the bottom of the sewage tank 130, and the air inlet 131 of the sewage tank is located at the top of the sewage tank 130.

[0205] It should be noted that the staggered opening means that the air inlet 131 of the sewage tank and the sewage outlet 133 of the sewage tank are not directly opposite to each other. Figure 2 As shown, the orthographic projection of the air inlet 131 of the sewage tank on the bottom surface of the sewage tank 130 does not overlap with the sewage outlet 133 of the sewage tank. This arrangement is beneficial to avoid the intersection of fresh air and dirty air and prevent air pollution; and this arrangement can effectively promote the flow of wind in the sewage tank 130, so that the wind in the sewage tank 130 can quickly reach the sewage outlet 133.

[0206] In some embodiments, the air inlet 131 of the sewage tank can be set at the top of the sewage tank 130 in the vertical direction. On the one hand, it is convenient to connect with the air inlet pipe 137; on the other hand, it is beneficial for the fan 120 to drive the airflow directly into the sewage tank 130 in the vertical direction, so that the flow area of ​​the airflow is maximized and the flow rate of the airflow reaches the maximum.

[0207] In some embodiments, the shape and number of the air inlet 131 of the sewage tank are not further limited. For example, the shape of the air inlet 131 of the sewage tank can be circular, square, etc.

[0208] In order to improve and optimize the pressurized sewage discharge effect of the sewage tank 130, in a possible implementation method, refer to Figure 3a As shown, at least part of the bottom surface of the sewage tank 130 may be an inclined surface, and the sewage outlet 133 of the sewage tank is opened at the lowest point of the sewage tank 130. This embodiment does not limit the inclination angle of the inclined surface.

[0209] In some embodiments, reference Figure 3b to Figure 3d As shown, the bottom of the sewage tank 130 may be funnel-shaped, and the sewage outlet 133 of the sewage tank 130 is opened at the lowest point of the sewage tank 130. The bottom of the sewage tank 130 of this embodiment may be conical (refer to Figure 3b As shown), wherein the bottom surface of the sewage tank 130 can be a plane (refer to Figure 3c As shown), the bottom surface of the sewage tank 130 may also be a curved surface (see Figure 3d In this way, the wind flow in the sewage tank 130 can be promoted to quickly reach the sewage outlet 133, speeding up the sewage discharge speed, thereby further optimizing the sewage cleaning effect of the sewage tank 130.

[0210] In order to improve and optimize the pressurized sewage discharge effect of the sewage tank 130, in a possible implementation method, refer to Figure 4 As shown, the sewage tank 130 may include an air inlet pipe 137, the air inlet pipe 137 is connected to the air inlet 131 of the sewage tank, and the diameter of the air inlet pipe 137 may gradually increase along the direction from the outside of the sewage tank 130 to the cavity of the sewage tank 130. In this way, the air inlet area of ​​the air inlet 131 of the sewage tank 130 can be increased, which is beneficial to increase the air volume of the fan 120 and improve the pressurization effect of the fan 120.

[0211] In some embodiments, reference Figure 4 As shown, the sewage tank 130 may include a sewage pipe 134, the sewage pipe 134 is connected to the sewage outlet 133 of the sewage tank, and the pipe diameter of the sewage pipe 134 may be gradually reduced along the direction from the cavity of the sewage tank 130 to the outside of the sewage tank 130. In this way, the air outlet area of ​​the sewage outlet 133 of the sewage tank 130 can be increased, which is beneficial to the sewage discharge speed and improves the sewage discharge effect.

[0212] In one possible implementation, referring to Figure 5 As shown, the main motor 110 may also be included, the main motor 110 is arranged in the main body 190, the working wind direction of the fan 120 is opposite to that of the main motor 110, and the sewage tank 130 is provided with a sewage inlet 132; the main motor 110 is connected to the sewage tank 130, and the main motor 110 is used to suck external sewage into the sewage tank 130 through the sewage inlet 132 of the sewage tank. In this way, the cleaning effect of quickly absorbing the sewage on the target surface to be cleaned can be achieved.

[0213] Among them, the working wind directions of the fan 120 and the main motor 110 are opposite, which means that when the fan 120 is running, the wind pressure is generated to pressurize the sewage in the sewage tank 130 so that the sewage is discharged through the sewage outlet 133. When the main motor 110 is running, the external sewage is sucked into the sewage tank 130 through the sewage inlet 132 of the sewage tank.

[0214] In one possible implementation, the sewage inlet 132 of the sewage tank 130 may be higher than the bottom surface of the sewage tank 130, which is beneficial to ensure that the sewage inlet 132 of the sewage tank 130 will not be submerged by sewage, and prevent the sewage in the sewage tank 130 from flowing back to the floor brush assembly 140 through the sewage inlet 132, thereby ensuring the cleaning effect of the surface to be cleaned. This embodiment does not limit the height of the sewage inlet 132 from the bottom surface of the sewage tank 130.

[0215] In a possible implementation, the sewage inlet 132 of the sewage tank 130 is located below the suction port 111 corresponding to the main motor. Exemplarily, the sewage inlet 132 may be directly below the suction port 111 corresponding to the main motor, or the sewage inlet 132 may be approximately directly below the suction port 111 corresponding to the main motor. This is beneficial to increase the suction effect of the sewage inlet 132 of the sewage tank.

[0216] It should be noted that the specific distance between the sewage inlet 132 and the suction port 111 corresponding to the main motor can be designed according to actual conditions. On the one hand, the distance between the sewage inlet 132 and the suction port 111 corresponding to the main motor cannot be too small, which is helpful to avoid the problem of sewage being sucked into the main motor 110 when the distance is too close; on the other hand, the distance between the sewage inlet 132 and the suction port 111 corresponding to the main motor cannot be too large, which is helpful to avoid the problem of weakened suction at the sewage inlet 132 of the sewage tank 130.

[0217] In one possible implementation, referring to Figure 5 As shown, the opening of the sewage inlet 132 of the sewage tank 130 can be toward the side wall of the sewage tank 130. In this way, when the fan 120 is pressurized, it is beneficial to reduce the air filling and pressure relief of the fan 120, thereby avoiding the backflow of sewage.

[0218] In some embodiments, the opening direction of the sewage inlet 132 of the sewage tank can avoid the opening direction of the suction port and the air inlet 131 of the sewage tank at the same time. In this way, when the main motor 110 is sucking, the sewage is prevented from being directly sucked into the main motor 110, reducing the risk of water corrosion of the main motor 110. It should be noted that the suction port of the sewage tank and the suction port 111 corresponding to the main motor of this embodiment are the same opening, and the suction port 111 corresponding to the main motor is connected to the output port of the main motor.

[0219] In a possible implementation, the sewage inlet 132 of the sewage tank 130 may be provided with a sewage inlet check valve, and external sewage flows into the sewage tank 130 through the sewage inlet check valve. The sewage inlet check valve means that the sewage flows into the sewage tank 130 along the sewage inlet 132 and cannot flow back. Such a setting is beneficial to prevent the reverse flow of sewage and further avoid the backflow of sewage.

[0220] In a possible implementation, the sewage inlet 132 of the sewage tank 130 may be provided with a sewage inlet solenoid valve, which controls the opening or closing of the sewage inlet 132. The opening sequence of the sewage inlet solenoid valve and the main motor 110 is not limited.

[0221] In some embodiments, when the main motor 110 starts running, the sewage inlet electromagnetic valve is opened synchronously, which is beneficial to ensure that the sewage suction is not interrupted, thereby improving the sewage suction efficiency and saving the sewage suction time. In some embodiments, after the main motor 110 runs for a preset time, the sewage inlet electromagnetic valve is opened, so that the negative pressure is sufficient to suck the sewage, so that the sewage suction rate of the fan 120 can reach the maximum, and the sewage suction effect is improved. It should be noted that this embodiment does not limit the preset time.

[0222] In one possible implementation, referring to Figure 5As shown, a floor brush assembly 140 may also be included, and the floor brush assembly 140 is arranged in the cleaning body 100. The floor brush assembly 140 has a sewage suction port 141, and the sewage suction port 141 is connected to the sewage inlet 132 of the sewage tank 130. When the main motor 110 is running, a negative pressure is formed in the sewage tank 130, and the sewage inlet 132 of the sewage tank 130 sucks external sewage into the sewage tank 130 through the sewage suction port 141. In this way, it is helpful to quickly suck back the sewage and achieve a cleaning effect on the surface to be cleaned.

[0223] In some embodiments, the suction port 111 corresponding to the main motor may be provided with a first moisture-proof solenoid valve, which is opened when the main motor 110 is running, and closed when the main motor 110 stops running. This arrangement helps prevent the sewage from flowing back when the sewage tank 130 is dumped, thereby ensuring that the main motor 110 is not contaminated. In some embodiments, the air inlet of the fan 120 may be provided with a second moisture-proof solenoid valve, which is opened when the fan 120 is running, and closed when the fan 120 stops running. This arrangement helps prevent the sewage from flowing back when the sewage tank 130 is dumped, thereby ensuring that the fan 120 is not contaminated.

[0224] In some embodiments, the suction port 111 corresponding to the main motor and the air inlet corresponding to the fan 120 can be separately arranged on the top of the sewage tank 130, so that the wind resistance is small and there is no interference with each other; in some embodiments, the suction port 111 corresponding to the main motor and the air inlet corresponding to the fan 120 can be interconnected to achieve opening sharing, and the wind force superposition can be achieved through the adaptive adjustment of forward and reverse rotation, so as to obtain a larger air volume and wind speed, and the connection is simple and easy to achieve. Exemplarily, the suction port 111 corresponding to the main motor and the air inlet corresponding to the fan 120 can be directly connected, or the suction port 111 corresponding to the main motor and the air inlet corresponding to the fan 120 can be connected through a three-way pipe.

[0225] In one possible implementation, referring to Figure 1 As shown, the cleaning device 200 may also include a base station 210, wherein the base station 210 is provided with a wind pressure interface 223 connected to the fan 120, so that when the fan 120 is set in the base station 210 and the cleaning body 100 is aligned and placed on the base station 210, the sewage tank 130 can be connected to the fan 120 through the wind pressure interface 223.

[0226] In one possible implementation, referring to Figure 1As shown, an auxiliary sewage tank 220 may also be included, and the auxiliary sewage tank 220 may be arranged in the base station 210, and the outlet 222 of the auxiliary sewage tank is connected to the external sewer. In this embodiment, the base station 210 may be provided with a sewage discharge interface 226 connected to the auxiliary sewage tank 220, so that when the cleaning device 200 cleaning body 100 is aligned and placed on the base station 210, the sewage discharge port 133 of the sewage tank is connected to the inlet 221 of the auxiliary sewage tank through the sewage discharge interface 226, thereby realizing the connection between the auxiliary sewage tank 220 and the sewage tank 130.

[0227] The reason for setting the auxiliary sewage tank 220 in this embodiment is that since the sewage in the sewage tank 130 generally also includes solid garbage such as particles and hair, directly discharging it into the sewer can easily cause the sewer pipe to be blocked and difficult to clear. Therefore, by including the auxiliary sewage tank 220, the auxiliary sewage tank 220 can be used as a transfer position after the sewage in the sewage tank 130 is extracted, which helps to extend the cleaning time of the sewage in the sewage tank 130; in addition, the auxiliary sewage tank 220 can separate the solid garbage and sewage in the sewage tank 130 to achieve the effect of solid-liquid separation, which helps to avoid the problem that the solid garbage in the sewage tank 130 is directly discharged into the sewer and causes the sewage pipe 134 to be blocked. In addition, there is no need to set up a separate solid-liquid separation device, which also helps to avoid the problem that the solid garbage in the sewage tank 130 is directly discharged into the sewer and causes the sewage pipe to be blocked.

[0228] The following describes the air circulation conditions of the cleaning device provided in the embodiments of the present application in the sewage discharge mode and the drying mode.

[0229] In some embodiments, the air circulation process of the cleaning device provided in the embodiment of the present application in the sewage discharge mode is: Figure 5 As shown, the main motor 110 is turned off, and the fan 120 is started. When the fan 120 is running, wind pressure is generated, and the fan 120 drives the wind flow along Figure 5 The sewage flows in the direction of arrow A in the figure, passes through the main motor 110 in sequence and reaches the sewage tank 130, pressurizing the sewage in the sewage tank 130, so that under the action of pressure, the sewage in the sewage tank 130 is discharged to the outside through the sewage outlet 133.

[0230] In some embodiments, the air circulation process of the cleaning device provided in the embodiment of the present application in the drying mode is as follows: Figure 5 As shown, the main motor 110 is started, the fan 120 is turned off, the main motor 110 forms wind pressure when running, and the main motor 110 drives the wind flow along Figure 5 The waste water flows in the direction of the middle arrow B, passes through the fan 120 in sequence to reach the floor brush assembly 140 , and circulates back to the waste water tank 130 .

[0231] The sewage discharge mode of the cleaning equipment provided in the embodiment of the present application will be described below in combination with the different distribution positions of the fans.

[0232] The first sewage discharge mode is: Figures 5 to 7 As shown, the cleaning device 200 includes a cleaning body 100 and a base station 210, a main motor 110 and a sewage tank 130 are arranged in the body 190, and a fan 120 is arranged in the base station 210. The sewage discharge process of this embodiment is as follows: start the sewage discharge process, turn off the main motor 110, turn on the fan 120, close the sewage suction port 141 of the floor brush assembly, open the sewage discharge port 133 of the sewage tank, generate wind pressure when the fan 120 is running, and drive the wind flow along the Figure 6 and Figure 7 The sewage in the sewage tank 130 is pressurized in the direction of the arrow A1 in the figure, so that under the action of the pressure, the sewage in the sewage tank 130 is discharged to the outside through the sewage outlet 133.

[0233] It should be noted that, in this embodiment, the main motor 110 can be in an on state, or the main motor 110 can also be in an off state. In this embodiment, the main motor 110 is mainly used as an example to explain in an off state, so that during sewage treatment, the main motor 110 only serves to connect the fan 120 and the sewage tank 130. In addition, by turning off the main motor 110, it is helpful to prevent the main motor 110 from sucking the sewage on the surface to be cleaned into the sewage tank 130, thereby avoiding the phenomenon of sewage discharge and sewage intake in the sewage tank 130 occurring simultaneously, further ensuring that the sewage in the sewage tank 130 is discharged to the greatest extent, and improving the sewage cleaning effect.

[0234] The second sewage discharge mode is as shown in reference 8, the cleaning device 200 includes a cleaning body 100 and a base station 210, the fan 120 and the sewage tank 130 are both arranged in the fuselage body 190, and the fan 120 is connected to the air inlet 131 of the sewage tank. The sewage discharge process of this embodiment is: start the sewage treatment, turn on the fan 120, close the sewage suction port 141 of the floor brush assembly, and open the sewage discharge port 133 of the sewage tank. When the fan 120 is running, wind pressure is generated, and the fan 120 drives the wind flow to pressurize the sewage in the sewage tank 130, so that under the action of pressure, the sewage in the sewage tank 130 is discharged to the outside through the sewage discharge port 133.

[0235] The third sewage discharge mode is: Fig. 9As shown, the cleaning device 200 includes a cleaning body 100 and a base station 210, a main motor 110 and a sewage tank 130 are arranged in the body 190, a fan 120 is arranged in the base station 210, a floor brush assembly 140 is arranged in the cleaning body 100, the sewage tank 130 is provided with a sewage inlet 132, the main motor 110 is connected with the sewage tank 130, the main motor 110 is used to suck external sewage into the sewage tank 130 through the sewage inlet 132 of the sewage tank, the floor brush assembly 140 has a sewage suction port 141, the sewage suction port 141 is connected with the sewage inlet 132, the fan 120 is connected to the floor brush assembly 140, and the fan 120 is connected with the sewage tank 130 through the sewage inlet 132 of the sewage tank.

[0236] In some embodiments, the sewage suction port 141 may be provided with a first valve 145, which is in a closed state when the fan 120 is running, and in an open state when the main motor 110 is running. In some embodiments, the sewage inlet 132 of the sewage tank may be provided with a three-way assembly 138, which is provided with a first inlet 1381 and a second inlet 1382, the first inlet 1381 is connected to the sewage suction port 141, and the second inlet 1382 is connected to the fan 120. In some embodiments, the passage connecting the main motor 110 and the sewage tank 130 may be provided with a second valve 139, which is in a closed state when the fan 120 is running; and in an open state when the main motor 110 is running.

[0237] In this way, under different working modes, it can be ensured that the process of pressurizing the sewage in the sewage tank 130 by the fan 120 and the process of sucking the external sewage by the main motor 110 are two separate processes, and the pressurization process and the suction process do not interfere with each other.

[0238] In some embodiments, the first valve may be one of an electrically controlled valve, a one-way valve and a solenoid valve, which is not limited in this embodiment. In some embodiments, the second valve may be one of an electrically controlled valve, a one-way valve and a solenoid valve, which is not limited in this embodiment. Among them, the electrically controlled valve may be implemented by using an ordinary small motor to drive the valve to rotate using a reduction gear box to achieve opening and closing, the one-way valve may be implemented by using a spring force or a reverse pressure of the fluid to achieve opening and closing, and the solenoid valve may be implemented by manual operation such as a handle, a screw twist, etc. to control the opening and closing of the valve. Through the above-mentioned valves, it can be ensured that the fan 120 will not interfere with each other during the pressurization process and the main motor 110 will not interfere with each other during the sewage suction process.

[0239] The normal sewage suction process of this embodiment is as follows: the sewage suction port 141 of the floor brush assembly is opened, the first valve 145 is opened, the first inlet 1381 is opened, the sewage inlet 132 of the sewage tank is opened, the second valve 139 is opened, and the sewage outlet 133 of the sewage tank 130 is closed. The main motor 110 sucks external sewage into the sewage tank 130. The sewage discharge process of this embodiment is as follows: the sewage suction port 141 of the floor brush assembly is closed, the first valve 145 is closed, the first inlet 1381 is closed, the sewage inlet 132 of the sewage tank is closed, the second valve 139 is closed, and the sewage outlet 133 of the sewage tank 130 is opened. The sewage is discharged to the outside through the sewage outlet 133.

[0240] The pressurization process of this embodiment is as follows: the sewage suction port 141 of the floor brush assembly is closed, the first valve 145 is closed, the first inlet 1381 is closed, the second inlet 1382 is opened, the sewage inlet 132 of the sewage tank is opened, the second valve 139 is closed, and the sewage outlet 133 of the sewage tank 130 is opened. When the fan 120 is running, the wind pressure is transmitted from the fan 120 through the floor brush assembly 140 to the inside of the sewage tank 130, pressurizing the sewage in the sewage tank 130, and the sewage is discharged to the outside through the sewage outlet 133.

[0241] The fourth sewage discharge mode is: refer to Fig.10 As shown, the cleaning device 200 includes a cleaning body 100 and a base station 210, a sewage tank 130 is arranged in the main body 190, and an auxiliary sewage tank 220 and a fan 120 are both arranged in the base station 210. The sewage discharge process of this embodiment is: start the sewage discharge process, open the sewage discharge port 133 of the sewage tank, open the inlet 221 of the auxiliary sewage tank, open the wind pressure interface 223 of the auxiliary sewage tank 220, and close the sewage discharge interface 226 of the auxiliary sewage tank. The fan 120 generates wind pressure during operation, and forms a negative pressure area above the sewage liquid level in the sewage tank 130, so that a pressure difference is formed inside and outside the sewage tank 130, thereby forming suction on the sewage in the sewage tank 130, and the sewage is discharged from the sewage discharge port 133 and along the Fig.10 The gas moves in the direction of the arrow A2 and is sucked into the auxiliary sewage tank 220 . The gas is discharged through the air outlet of the fan 120 along the direction of the arrow A2 . The solid waste is deposited in the auxiliary sewage tank 220 under the action of gravity.

[0242] The fifth sewage discharge mode is: refer to Fig.11As shown, the cleaning device 200 includes a cleaning body 100 and a base station 210, a sewage tank 130 is arranged in the main body 190, and an auxiliary sewage tank 220 and a fan 120 are both arranged in the base station 210. The sewage discharge process of this embodiment is: start the sewage discharge process, close the sewage outlet 133 of the sewage tank, close the inlet 221 of the auxiliary sewage tank, open the wind pressure interface 223 of the auxiliary sewage tank 220, and open the sewage outlet 226 of the auxiliary sewage tank. When the fan 120 is running, wind pressure is formed, and the fan 120 drives the wind flow to pressurize the sewage in the auxiliary sewage tank 220 along the direction of arrow A3, so that under the action of pressure, the sewage in the auxiliary sewage tank 220 is discharged to the outside through the sewage outlet 133.

[0243] It should be noted that this embodiment includes but is not limited to the above-mentioned multiple fan distribution methods and corresponding sewage discharge modes.

[0244] After the sewage is discharged, in order to prevent the problem of pipeline blockage and difficulty in clearing caused by solid waste discharge, it is necessary to clear the sewage pipe 134 and the auxiliary sewage pipe 225 after the sewage is discharged. Figures 12 to 19 As shown, a dredging pump 260 can also be provided in the base station 210, which helps to effectively dredge the sewage pipe 134 and the auxiliary sewage pipe 225 to ensure that the sewage can be discharged smoothly, and there is no need for users to clean it, which can reduce the frequency of users maintaining the base station 210.

The dredging process of this embodiment is as follows: the sewage in the sewage tank 130 is discharged into the sewage pipe 134 of the sewage tank 130 through the sewage outlet 133, and the auxiliary clean water tank 240 (refer to Fig.16 ) or an external clean water source 230 (refer to Fig.17 As shown), under the water pump pressure of the dredging pump 260, clean water is transported to the auxiliary sewage pipe 134 through the inlet 261 and the outlet 262 of the dredging pump in turn, so as to dredge the interior of the sewage pipe 134.

[0256] It should be noted that, in the above-mentioned dredging process, the inlet 261 of the dredging pump, the outlet 262 of the dredging pump, and the sewage outlet 133 of the sewage tank are all in an open state.

[0258] In some embodiments, reference Fig.18 As shown, the outlet of the floor brush water pump 143 can be connected to the sewage pipe 134 of the sewage tank 130. The dredging process of this embodiment is as follows: the sewage in the sewage tank 130 is discharged to the sewage pipe 134 of the sewage tank 130 through the sewage outlet 133, the clean water tank 160 is opened, and under the water pump pressure of the floor brush water pump 143, the clean water is sequentially transported to the sewage pipe 134 of the sewage tank 130 through the inlet of the floor brush water pump 143 and the outlet of the floor brush water pump 143, and the interior of the sewage pipe 134 is dredged.

[0259] In some embodiments, the auxiliary sewage pipe 225 is connected to the outlet 222 of the auxiliary sewage tank, and the outlet of the floor brush water pump 143 is connected to the auxiliary sewage pipe 225. The dredging process of this embodiment is: open the clean water tank 160, and under the water pump pressure of the floor brush water pump 143, clean water is sequentially transported to the auxiliary sewage through the inlet and outlet of the floor brush water pump 143 to dredge the inside of the auxiliary sewage.

[0260] The fifth dredging mode is: refer to Fig.19As shown, the base station 210 may be provided with a dredging agent supplying member 250. Exemplarily, the dredging agent supplying member 250 is also called a pipeline dredging agent, which includes solid and liquid forms. When the pipeline is blocked, the pipeline dredging agent is quantitatively added to soften the blockage and then dredge the blockage accordingly, thereby further dredging the sewage pipe 134 and the auxiliary sewage pipe 225, and effectively preventing the sewage pipe 134 and the auxiliary sewage pipe 225 from being blocked.

[0261] In some embodiments, the unclogging agent supplying member 250 may be connected to the drain pipe 134 of the sewage tank 130 to unblock the drain pipe 134 of the sewage tank 130. In some embodiments, the unclogging agent supplying member 250 may be connected to the auxiliary drain pipe 225 to unblock the auxiliary drain pipe 225.

[0262] After the dredging is completed, in order to keep the cleaning device 200 dry and clean, in this embodiment, Fig. 20 As shown, a drying component 150 may also be included. The drying component 150 may be disposed in the cleaning body 100, or the drying component 150 may be disposed in the base station 210, which is not limited in this embodiment. The drying component 150 heats or dehumidifies the air flow delivered by the main motor 110 and the fan 120. In this way, the cleaning body 100 and the base station 210 can be ensured to be dry and clean.

[0263] The drying process of the drying component 150 of the embodiment of the present application is as follows: after the drying instruction is started, the main motor 110 is turned on, the fan 120 is turned off, the sewage suction port 141 of the floor brush component is opened, and the sewage discharge port 133 of the sewage tank is closed. The main motor 110 generates wind pressure when running and drives the wind flow along the Fig. 20 The direction of the middle arrow A4 passes through the fan 120 in turn to reach the floor brush assembly 140 and circulates back to the sewage tank 130.

[0264] In some embodiments, the transported air flow is heated or dehumidified by the wind flow of the main motor 110. Therefore, in this embodiment, the electronic components of a drying fan can be saved, which helps to save space. In addition, there is no need to set up a separate drying fan outside. In addition, a fully closed loop is formed between the main motor 110, the fan 120, the floor brush assembly 140 and the sewage tank 130, which is conducive to the fastest heating or dehumidification to the greatest extent.

[0265] In some embodiments, the drying assembly 150 may include a heating element. For example, the heating element in this embodiment may be a heating wire. The heating element is electrically connected to the controller. For example, the heating element and the controller may be electrically connected in a wired manner, or the heating element and the controller may be electrically connected in a wireless manner.

[0266] The heating wire is a common heating element, which is heated by the resistance heat effect generated when the current passes through it. When the washing is in drying mode, the controller controls the heating element to turn on, which is beneficial to further dry the water vapor in the water channel and the air channel, ensuring the drying effect of the water channel and the air channel.

[0267] For example, the distribution position and the distribution quantity of the heating element are not further limited. For example, the heating element can be distributed in the middle section of the pipeline along the extension direction of the pipeline, or the heating element can also be distributed in other positions of the pipeline. In this embodiment, the heating element is mainly distributed in the middle section of the pipeline as an example for description.

[0268] In some embodiments, the drying component 150 may include a drying element. Exemplarily, the drying element in this embodiment may be a desiccant. The desiccant is a dehumidifying agent that absorbs moisture from the atmosphere. Its drying principle is to absorb moisture or decompose moisture into other substances through a catalyst reaction. It can effectively absorb moisture in the surrounding air, thereby reducing the humidity of the surrounding environment and maintaining a dry state.

[0269] In some embodiments, the drying assembly 150 may include a condensation member. Exemplarily, the condensation member in this embodiment may be a condenser. The condenser is a heat transfer device, and the working principle of the condenser is to achieve heat transfer based on the latent heat released or absorbed during the phase change of the substance. The condensation member includes a condensation inlet and a condensation outlet, the condensation inlet is located on the side of the condensation outlet close to the fan 120, and the condensation outlet is connected to the outside. The outside or inside of the condenser can be set with a condenser pipeline, the condenser pipeline has a condenser, and the condenser has a substance to be cooled, and the condenser can exchange heat with the substance to be cooled through the tube wall. Exemplarily, a high-temperature medium (such as water vapor) is passed into the condenser through the condensation inlet, and a low-temperature medium (such as cooling water) is injected into the condenser pipeline. The heat of the water vapor will be absorbed by the cooling water, and the high-temperature, high-pressure water vapor will gradually condense into liquid water, and the liquid water flows out from the condensation outlet to the outside. In this way, the water vapor in the pipeline can be transferred to the outside, thereby achieving a dehumidification effect.

[0270] In one possible implementation, referring to Figure 21 to Figure 24 As shown, a sewage inlet pipe 135 may be provided in the sewage tank 130, and the inlet of the sewage inlet pipe 135 is located in the cavity of the sewage tank 130. In this way, after the floor brush assembly 140 finishes cleaning the surface to be cleaned, the sewage on the surface to be cleaned is sucked back into the cavity of the sewage tank 130 through the sewage inlet pipe 135.

[0271] There is an air duct connected between the floor brush assembly 140 and the sewage tank 130. When the cleaning device 200 is in normal working state, the air duct needs to be opened to ensure that the sewage can be sucked back into the cavity of the sewage tank 130 through the air duct and the sewage inlet pipe 135 in sequence. When the cleaning device 200 is in the off state or the auxiliary sewage tank 220 is draining, the air duct needs to be sealed to ensure that the sewage in the sewage tank 130 does not flow back to the floor brush assembly 140 through the sewage inlet pipe 135.

[0272] Therefore, in the embodiments of the present application, reference is made to Figure 21 to Figure 24 As shown, in order to achieve the opening and sealing of the air duct between the floor brush assembly 140 and the sewage tank 130, a one-way valve 170 can be provided at the inlet of the sewage inlet pipe 135, wherein the one-way valve 170 has an open state and a closed state. When the sewage inlet pipe 135 is inflowing water, the one-way valve 170 is in the open state, and when the sewage inlet pipe 135 stops inflowing water, the one-way valve 170 is in the closed state.

[0273] Specifically, refer to Fig. 22 and Fig.24 As shown, the one-way valve 170 may include a valve body 171 and a counterweight 172, wherein the valve body 171 is movably connected to the pipe opening of the sewage inlet pipe 135, and the counterweight 172 is connected to the valve body 171. When the sewage inlet pipe 135 stops inflowing water, the valve body 171 covers the pipe opening of the sewage inlet pipe 135 under the gravity of the counterweight 172, forming a closed state of the one-way valve 170.

[0274] In some embodiments, reference Fig. 22 As shown, the counterweight member 172 includes a counterweight bracket 173 and a counterweight block 174, the valve body 171 can be a valve plate, the valve plate is rotatably connected to the pipe mouth of the sewage inlet pipe 135, one end of the counterweight bracket 173 is connected to the rotating shaft 175 of the valve plate, and the other end of the counterweight bracket 173 is connected to the counterweight block 174.

[0275] For example, refer to Fig. 22 As shown, the valve plate can be rotatably connected to the pipe opening of the sewage inlet pipe 135 via a rotating shaft 175, and the rotating shaft 175 is the rotation center of the valve plate. The counterweight block 174 is a heavy object used to increase its own weight to maintain balance, thereby helping to lower the center of gravity of the one-way valve 170. Alternatively, the center of gravity of the one-way valve 170 can also be lowered by increasing the thickness of the counterweight bracket 173.

[0276] The working process of the one-way valve 170 of this embodiment is as follows: when the cleaning device 200 is turned on, the sewage inlet 132 of the sewage tank is opened, and the main motor 110 drives the airflow to suck the sewage on the floor brush assembly 140 or the surface to be cleaned (suction along the direction from the floor brush assembly 140 to the sewage tank 130). As the airflow continuously impacts the sewage inlet pipe 135 through the sewage inlet 132 of the sewage tank, and the cleaning device 200 itself tilts, causing the center of gravity of the one-way valve 170 to change, the valve plate rotates around the rotating shaft 175 in a first direction, the valve plate is separated from the pipe mouth of the sewage inlet pipe 135, and the air duct between the floor brush assembly 140 and the sewage tank 130 is opened. When the cleaning device 200 is turned off, the sewage inlet pipe 135 stops taking in water. When the cleaning device 200 remains in an upright state or is placed at the base station 210, the valve plate rotates in the second direction around the rotating shaft 175 under the action of the gravity of the counterweight block 174. The valve plate covers the pipe opening of the sewage inlet pipe 135, and the air duct between the floor brush assembly 140 and the sewage tank 130 is sealed.

[0277] Exemplarily, the first direction may be a counterclockwise direction, and the second direction may be a clockwise direction.

[0278] In some embodiments, reference Fig.24 As shown, the counterweight 172 includes a counterweight block 174, and the valve body 171 can be a valve cylinder, which is slidably connected to the pipe mouth of the sewage inlet pipe 135, and the counterweight block 174 is connected to the valve cylinder.

[0279] The working process of the one-way valve 170 of this embodiment is as follows: when the cleaning device 200 is turned on, the sewage inlet 132 of the sewage tank is opened, and the main motor 110 drives the airflow to suck the sewage on the floor brush assembly 140 or the surface to be cleaned (suction along the direction from the floor brush assembly 140 to the sewage tank 130). As the airflow continuously impacts the sewage inlet pipe 135 through the sewage inlet 132 of the sewage tank, the valve cylinder slides upward in the vertical direction on the sewage inlet pipe 135, the valve cylinder is separated from the pipe mouth of the sewage inlet pipe 135, and the air duct between the floor brush assembly 140 and the sewage tank 130 is opened. When the cleaning device 200 is turned off, the sewage inlet pipe 135 stops taking in water. When the cleaning device 200 remains upright or is placed at the base station 210, the valve cylinder slides downward in the vertical direction on the sewage inlet pipe 135 under the action of the gravity of the counterweight block 174, and the valve cylinder covers the pipe mouth of the sewage inlet pipe 135, and the air duct between the floor brush assembly 140 and the sewage tank 130 is sealed.

[0280] In some embodiments, the one-way valve 170 and the pipe mouth of the sewage inlet pipe 135 may be provided with magnetic adsorption parts. Exemplarily, the pipe mouth of the sewage inlet pipe 135 may be provided with a magnet, and the one-way valve 170 and the pipe mouth of the sewage inlet pipe 135 may be provided with a magnet at the matching position. When the cleaning device 200 is turned on, the airflow impacts the one-way valve 170 to open the pipe mouth of the sewage inlet pipe 135. When the cleaning device 200 is turned off, the one-way valve 170 is affected by the magnetic adsorption force, and the air duct between the floor brush assembly 140 and the sewage tank 130 is sealed.

[0281] In some embodiments, the one-way valve 170 and the pipe opening of the sewage inlet pipe 135 may be provided with an elastic connector. Exemplarily, the one-way valve 170 and the pipe opening of the sewage inlet pipe 135 may be connected in cooperation with a spring. When the cleaning device 200 is turned on, the airflow impacts the one-way valve 170 to open the pipe opening of the sewage inlet pipe 135. When the cleaning device 200 is turned off, under the gravity of the counterweight 174 and the elastic force of the spring, the one-way valve 170 covers the pipe opening of the sewage inlet pipe 135, and the air duct between the floor brush assembly 140 and the sewage tank 130 is sealed.

[0282] In some embodiments, the cleaning body 100 may be provided with a floor brush assembly 140, an extrusion member and a driving member. The floor brush assembly 140 includes a floor brush 142 and a floor brush hose 144 that are interconnected. The floor brush 142 is connected to the sewage inlet pipe 135 at least through the floor brush hose 144. The extrusion member is connected to the driving member, and the extrusion end of the extrusion member is facing the floor brush hose 144. The driving member drives the extrusion member to squeeze the floor brush hose 144 to disconnect the floor brush 142 from the sewage inlet pipe 135.

[0283] For example, the floor brush hose 144 may be made of a rubber-coated component, and specifically, may be made of materials such as silicone, rubber, etc. For example, the driving component may be a driving motor.

[0284] The two ends of the rubber-coated part are circular hard rubber, the middle is soft rubber, and the extrusion part is arranged on both sides of the soft rubber and can reciprocate. When the cleaning device 200 is in a normal state, the extrusion part does not contact and squeeze the soft rubber, and the sewage suction channel of the floor brush 142 is unobstructed; when the cleaning device 200 needs to discharge sewage, the driving part drives the extrusion part to squeeze the floor brush hose 144, the sewage suction channel of the floor brush 142 is closed, and the floor brush 142 is disconnected from the sewage inlet pipe 135, thereby realizing the opening and sealing of the air duct between the sewage tank 130 and the floor brush assembly 140.

[0285] It should be noted that the ways of opening and sealing the air duct between the sewage tank 130 and the floor brush assembly 140 include but are not limited to the above-mentioned ways, and this embodiment does not limit this.

[0286] Reference Fig.25As shown, an embodiment of the present application provides a cleaning system, the cleaning system includes a cleaning device 200, the cleaning device 200 may include a cleaning body 100, the cleaning body 100 is provided with a main motor 110 and a sewage tank 130, the main motor 110 is connected to the sewage tank 130, and the sewage tank 130 has a sewage inlet 132 and a sewage outlet 133. Among them, the main motor 110 is used to suck external sewage into the sewage tank 130 through the sewage inlet 132 of the sewage tank 130, so that the cleaning effect of quickly absorbing the sewage on the target surface to be cleaned can be achieved.

[0287] In order to further improve the self-cleaning effect of the sewage tank 130, in the embodiment of the present application, refer to Fig.26 As shown, when the cleaning body 100 is in the pressurized sewage discharge mode, the sewage outlet 133 is in an open state and the main motor 110 is turned off. Under the action of external force, gas enters the sewage tank 130 through the sewage inlet 132 to achieve positive pressure, and controls the sewage in the sewage tank 130 to be discharged through the sewage outlet 133.

[0288] It should be noted that the gas enters the sewage tank 130 through the sewage inlet 132 means that the gas enters the sewage tank 130 by means of external force. For example, the external force pressurization can be achieved by setting a fan, and the fan is connected to the sewage inlet 132 of the sewage tank 130. In this way, when the fan is running, the wind pressure is formed to pressurize the sewage in the sewage tank 130, so that the sewage can be discharged smoothly through the sewage outlet 133.

[0289] Through the above solution, the sewage tank 130 can be effectively self-cleaned better. Specifically, when cleaning equipment, such as a floor scrubber, is cleaning, it will suck dirt into the sewage tank 130, including some hair, etc., and the dirt is easy to adhere to the sewage tank 130. It is very troublesome to clean the sewage tank 130. In this case, pressure is applied to the sewage tank 130 when the sewage tank 130 is discharging sewage, so that the dirt is pressed out by a larger pressure. Therefore, under the condition of positive pressure, the dirt is more easily discharged.

[0290] In a conceivable scenario, the inner wall of the sewage tank 130 is stuck with hair and other dirt. Since there is a positive pressure in the sewage tank 130, the pressure is greater when the sewage is discharged, which can easily wash the inner wall surface, thereby taking away the hair and the like. In another scenario, since the pressurization is performed by gas, even if the water in the sewage tank 130 cannot cover the stuck hair, the high-pressure gas will blow the above-mentioned hair, thereby taking away the above-mentioned dirt.

[0291] Based on this, it can be seen that compared with the prior art, this solution can better realize the self-cleaning of the sewage tank 130, with better effect, and can target more scenarios, making the cleaning of the sewage tank 130 more convenient.

[0292] In the embodiment of the present application, in order to further self-clean the sewage tank 130, the main motor 110 is turned on, and the main motor 110 applies a negative pressure force to the sewage discharged at the sewage outlet 133, so that the discharged sewage is sucked back into the sewage tank 130 through the sewage outlet 133. In this way, the sewage under the pressurized effect and the sewage under the negative pressure are compatible at the sewage outlet 133 to form a surge, which helps to fully clean various positions in the middle and lower regions of the sewage tank 130, and further helps to improve the cleaning effect of the sewage tank 130, so as to ensure that the sewage tank 130 is cleaned.

[0293] Among them, “surge” means that under the simultaneous action of pressurization and negative pressure, the sewage at the sewage outlet 133 will form a rolling state in the middle and lower area of ​​the sewage tank 130, which can ensure that all positions in the middle and lower part of the sewage tank 130 are cleaned, thereby improving the cleaning effect of the sewage tank 130.

[0294] For example, refer to Fig.26 As shown, the gas can flow along Fig.26 The sewage in the sewage tank 130 flows in the direction of the middle arrow A1. The sewage in the sewage tank 130 is discharged from the sewage tank 130 along the direction of A1 under the action of pressure, and the discharged sewage is sucked back into the sewage tank 130 through the sewage outlet 133 along the direction of the arrow A2 under the action of negative pressure.

[0295] In one possible implementation, referring to Fig.25 and Fig.26 As shown, the cleaning body 100 is provided with a floor brush 142, a floor brush hose 144 is provided inside the floor brush 142, and the floor brush hose 144 is connected to the sewage inlet 132. When the cleaning body 100 is in the pressurized sewage discharge mode, under the action of external force, the gas enters the sewage inlet 132 through the floor brush hose 144 and pressurizes the sewage tank 130.

[0296] In the embodiment of the present application, a method of increasing pressure from the floor brush 142 is adopted, and a floor brush hose 144 can be used to make the cleaning equipment as small as possible to achieve a better effect. Specifically, the current cleaning equipment, such as a floor scrubber, has a floor brush hose 144 for sucking dirt on its floor brush 142, and the floor brush hose 144 is connected to the sewage tank 130, so that during the cleaning process, the dirt can be sucked into the sewage tank 130 by the floor brush hose 144.

[0297] In the above-mentioned pressurized sewage discharge, in order to achieve the connection with the sewage tank 130, the floor brush hose 144 is cleverly and directly utilized, and there is no need to add other air inlets to achieve the above-mentioned effect. This not only ensures the pressurized effect, but also prevents major modifications to the existing cleaning equipment, thereby increasing costs.

[0298] In one possible implementation, referring to Fig.26 and Fig. 27 As shown, the cleaning device 200 may also include a base station 210, on which a base station air outlet 270 and a base station motor 280 are provided; when the cleaning body 100 is installed on the base station 210 and is in a pressurized sewage discharge mode, the base station air outlet 270 is connected to the sewage inlet 132 of the sewage tank 130, and the base station motor 280 is used to pass the gas into the sewage tank 130 through the base station air outlet 270 and the sewage inlet 132.

[0299] For example, refer to Fig. 27 As shown, a main body docking portion 294 is provided on the base station 210 , and the cleaning body 100 and the base station 210 are aligned and installed through the main body docking portion 294 .

[0300] In the embodiment of the present application, wind pressure is generated when the base station motor 280 is running, so that the gas is passed into the sewage tank 130 under the wind pressure of the base station motor 280. The gas can be external gas. It should be noted that the specific installation position of the base station motor 280 on the base station 210 is not limited.

[0301] It can be understood that the base station air outlet 270 is a connecting port set on the base station 210, and the base station air outlet 270 connects the inner cavity and the outside of the base station 210. The shape, size, position, etc. of the base station air outlet 270 are not limited and can be set specifically according to the actual product.

[0302] In this way, when the base station motor 280 is in the non-pressurized sewage discharge mode, the base station air outlet 270 can be blocked, which is beneficial to ensure the sealing of the base station 210, improve the sealing effect of the base station 210, and effectively prevent the base station 210 from being easily damaged by water, thereby ensuring the normal operation of the base station 210 and extending the service life of the base station 210; when the cleaning body 100 is installed on the base station 210 and is in the pressurized sewage discharge mode, the base station air outlet 270 is connected to the sewage inlet 132 of the sewage tank 130, so that the wind pressure formed by the operation of the base station motor 280 will pass the gas into the sewage tank 130 through the base station air outlet 270 and the sewage inlet 132 in turn.

[0303] In some embodiments, the communication mode between the base station air outlet 270 and the sewage inlet 132 of the sewage tank 130 is not limited. For example, the base station air outlet 270 and the sewage inlet 132 of the sewage tank 130 can be connected through a pipeline. This embodiment does not limit this.

[0304] In one possible implementation, a main body air outlet may be provided on the cleaning body 100; when the cleaning body 100 is in the pressurized sewage discharge mode, the main body air outlet is connected to the sewage inlet 132 of the sewage tank 130; when the cleaning body 100 is installed on the base station 210, the main body air outlet is connected to and connected to the base station air outlet 270.

[0305] It is understandable that the main air outlet is a connecting port provided on the cleaning body 100, and the main air outlet is connected to the sewage inlet 132 of the sewage tank 130 and the outside. The specific installation position of the main air outlet on the cleaning body 100 is not limited. In the embodiment of the present application, the main air outlet is mainly provided on the floor brush as an example for explanation. In addition, the shape and size of the main air outlet are not limited, and can be specifically set according to the actual product.

[0306] In this way, when the cleaning body 100 is in the non-pressurized sewage discharge mode, the main body air outlet can be blocked, which is beneficial to ensure the sealing of the cleaning body 100, improve the sealing effect of the cleaning body 100, and effectively prevent the cleaning body 100 from being easily damaged by water, thereby ensuring the normal operation of the cleaning body 100 and extending the service life of the cleaning body 100; when the cleaning body 100 is installed on the base station 210 and is in the pressurized sewage discharge mode, the main body air outlet is connected and communicated with the base station air outlet 270, so that the wind pressure formed by the operation of the base station motor 280 will pass the gas into the sewage tank 130 through the base station air outlet 270, the main body air outlet and the sewage inlet 132 of the sewage tank 130 in sequence.

[0307] In some embodiments, the communication mode between the main body air outlet and the sewage inlet 132 of the sewage tank 130 is not limited. For example, the main body air outlet and the sewage inlet 132 of the sewage tank 130 can be connected to each other through a pipeline. This embodiment does not limit this.

[0308] In a possible implementation, a switch valve 136 may also be included. The switch valve 136 is arranged at the sewage outlet 133 of the sewage tank 130 and is configured to control the sewage outlet 133 to be opened or closed; when the cleaning body 100 is in the pressurized sewage discharge mode, the switch valve 136 is in an open state.

[0309] For example, the switch valve 136 of this embodiment can be an electrically controlled valve or a solenoid valve, wherein the electrically controlled valve can be realized by using an ordinary small motor to drive the valve to rotate using a reduction gear box to achieve opening and closing, which is not limited in this embodiment.

[0310] In one possible implementation, referring to Fig. 27 and Fig.28 As shown, an air outlet valve 300 is provided at the air outlet 270 of the base station, and the air outlet valve 300 is used to open or close the air outlet 270 of the base station. In this way, when the base station 210 is in the non-pressurized sewage discharge mode, the air outlet valve 300 can be used to block the air outlet 270 of the base station, which is beneficial to ensure the sealing performance of the base station 210 and improve the sealing effect of the base station 210. When the cleaning body 100 is in the pressurized sewage discharge mode, the air outlet valve 300 is opened.

[0311] In the embodiment of the present application, the type of the air outlet valve 300 is not limited. For example, the air outlet valve 300 may be an elastic reset valve, or the air outlet valve 300 may be an electric control valve or a solenoid valve. This is not limited in the present embodiment.

[0312] In the embodiment of the present application, the air outlet valve 300 is mainly used as an elastic reset valve as an example for explanation. In this way, when the base station 210 is in the pressurized sewage discharge mode, the base station motor 280 applies pressure to the air outlet valve 300, the air outlet valve 300 opens under the action of wind pressure, and the base station air outlet 270 opens; when the base station 210 is in the non-pressurized sewage discharge mode, the air outlet valve 300 returns to its original state under the elastic force to block the base station air outlet 270, and the base station air outlet 270 closes, which helps to quickly realize the opening or closing of the base station air outlet 270, and can effectively ensure the good sealing of the base station 210.

[0313] In one possible implementation, referring to Fig.29 and Fig.30 As shown, it can also include an air outlet motor 400, which is arranged in the base station 210, and the air outlet of the air outlet motor 400 is connected to the base station air outlet 270; when the cleaning body 100 is in the pressurized sewage discharge mode, the air outlet motor 400 is used to apply pressure to the air outlet valve 300 to open the air outlet valve 300.

As long as the air outlet switch part can be opened and closed and connected to the opening of the air outlet valve body 310, it belongs to the protection scope of the present application.

[0319] In the embodiment of the present application, in order to further ensure the sealing of the base station 210, refer to Fig.31 As shown, a sealant 330 can be provided at the edge of the base station air outlet 270, which can be, for example, soft glue, so as to help form a seal and thereby isolate the base station 210 from the outside world, and prevent water and other debris from entering the base station 210 from the base station air outlet 270, thereby ensuring good sealing of the base station 210, ensuring the normal operation of the base station 210, and extending the service life of the base station 210.

[0320] In one possible implementation, referring to Figure 32 to Figure 34 As shown, the base station air duct 510 and the air duct valve 700 may also be included. The base station motor 280 is connected to the base station air outlet 270 through the base station air duct 510, and the air duct valve 700 is arranged in the base station air duct 510. In actual application, the air duct valve 700 is used to shut off or open the conduction of the base station air duct 510; when the cleaning body 100 is in the pressurized sewage discharge mode, the air duct valve 700 opens the connection of the base station air duct 510. In this way, it is conducive to realizing the shutoff or conduction of the base station air duct 510, and the operation convenience is high.

[0321] In the embodiment of the present application, the type of the air duct valve 700 is not limited. For example, the air duct valve 700 may be an elastic reset valve, or the air duct valve 700 may be an electric control valve or a solenoid valve. This is not limited in the present embodiment.

[0322] In the embodiment of the present application, the air duct valve 700 is mainly described as an elastic reset valve. In this way, when the base station 210 is in the pressurized sewage discharge mode, the base station motor 280 applies pressure to the air duct valve 700, and the air duct valve 700 opens under the action of wind pressure, and the base station air duct 510 is connected. When the base station 210 is in the non-pressurized sewage discharge mode, the air duct valve 700 returns to its original state under the elastic force to close the base station air duct 510, thereby helping to quickly achieve the closing or opening of the base station air duct 510.

[0323] In the embodiment of the present application, there is no limitation on the specific location of the air duct valve 700 in the base station air duct 510, and it can be arranged according to actual needs.

[0324] In the present application, refer to Fig.33 As shown, a wind shield 500 may also be included, and a base station air duct 510 is formed in the wind shield 500. A wind duct inlet 520 is provided on the wind shield 500, so that gas enters the base station air duct 510 through the wind duct inlet 520. The wind duct inlet 520 is provided with a circular hole, and the direction of the circular hole can be horizontal to the ground, which helps to prevent water from splashing into the wind duct inlet 520. It should be noted that the embodiment of the present application does not limit the shape, number, and arrangement of the wind duct inlet 520.

[0325] In the present application, refer to Fig.32 and Fig.33 As shown, the outer periphery of the air duct inlet 520 may be wrapped with a silencer 550, and illustratively, the silencer 550 may be silencer cotton, wherein the silencer cotton is made of sponge material, which is beneficial to achieve the noise reduction function of the air duct inlet 520. It should be noted that the material of the silencer 550 is not limited in this embodiment.

[0326] In the present application, refer to Fig.33 As shown, the wind shield 500 may be provided with a first air outlet 530 and a second air outlet 540, wherein the first air outlet 530 is located on a side close to the air duct inlet 520, and the first air outlet 530 may be composed of a circular hole, which is not limited in this embodiment. The second air outlet 540 is provided between the first air outlet 530 and the base station air outlet 270, that is, the second air outlet 540 is located on the gas flow path of the base station air duct 510, wherein the opening position of the first air outlet 530 and the opening position of the second air outlet 540 may be 180° apart, which is beneficial to extend the base station air duct 510 and thus achieve a noise reduction effect.

[0327] In one possible implementation, referring to Fig.34 and Fig.35As shown, the base station air duct 510 may be provided with an air duct drain port 560, and the air duct drain port 560 is located on the side of the air duct valve 700 close to the base station air duct 270. In this way, when the base station motor 280 is in a non-working state, the air duct drain port 560 is in an open state. If impurities such as water enter the base station air duct 510 from the base station air duct 270, they will first flow out through the air duct drain port 560, which is beneficial to avoid the problem that impurities such as water enter the base station motor 280 and damage the base station motor 280, thereby ensuring the normal operation of the base station motor 280 and extending the service life of the base station motor 280. When the cleaning body 100 is in a pressurized sewage discharge mode, the air duct valve 700 is opened under the wind pressure of the base station motor 280, and the air duct valve 700 blocks the air duct drain port 560, thereby forming a sealed state of the air duct drain port 560, which helps to reduce the wind loss in the base station air duct 510 and ensure the normal flow of gas, thereby ensuring that there is a strong enough wind force to enter the sewage tank 130.

[0328] In one possible implementation, referring to Fig.34 As shown, the air duct valve 700 may include an air duct valve body 710, an air duct switch part 720, an air duct rotating part 740 and an air duct elastic part 730.

In this way, when the base station motor 280 is in a non-working state, the air duct switch part 720 blocks the base station air duct 510 under the action of the air duct elastic part 730; when the cleaning body 100 is in a pressurized sewage discharge mode, the air duct switch part 720 rotates under the action of the wind pressure of the base station motor 280, and the air duct switch part 720 covers the air duct drain port 560, thereby forming a seal with the air duct drain port 560. This helps to reduce wind loss in the base station air duct 510, ensures the normal flow of gas, and ensures that there is strong enough wind to enter the sewage tank 130.

[0329] In the embodiment of the present application, the type of the air duct elastic part 730 is not limited. For example, the air duct elastic part 730 in the present embodiment may be a tension spring; or the air duct elastic part 730 may be a spring; or the air duct elastic part 730 may be other components with elastic force and elastic restoring force. In the embodiment of the present application, the air duct elastic part 730 is mainly described as a tension spring.

[0330] In the embodiment of the present application, there is no limitation on the structure and connection method of the air duct valve body 710 and the air duct switch part 720. As long as the air duct switch part 720 and the air duct valve body 710 can be rotatably connected, they belong to the protection scope of the present application.

[0331] In one possible implementation, referring to Fig.35 As shown, a sealing valve 600 may also be included, and the sealing valve 600 may be made of a soft rubber material. In this way, when the base station 210 is in a non-working state, the sealing valve 600 will not be deformed, and the air duct drain port 560 is in an open state. If water enters the base station air duct 510 from the base station air port 270, it will first flow out from the air duct drain port 560 and will not enter the base station motor 280; when the base station motor 280 is in a working mode, the sealing valve 600 is deformed under the action of wind pressure, and the sealing valve 600 snaps on the air duct drain port 560, so that the air duct drain port 560 forms a seal, thereby reducing the wind loss in the base station air duct 510.

In this way, the drying component 800 heats and dehumidifies the air flow delivered by the base station motor 280, so that the cleaning body 100 and the base station 210 can be ensured to be dry and clean.

[0333] In the embodiment of the present application, the type of the drying component 800 is not limited. For example, the drying component 800 may include a heating element, a condensing element, and a drying element. For example, the heating element may be a heating wire, and the condensing element may be a condensing tube. In the embodiment of the present application, the drying component 800 is mainly described as a heating wire.

[0334] Continue to refer to Fig.36 As shown, the base station air duct 510 has a bottom, and the vertical height of the drying assembly 800 can be higher than the bottom. Fig.36 As shown at position A in the middle, such a configuration helps to prevent water from entering the base station air duct 510 and causing the drying component 800 to be immersed in water, thereby ensuring the normal operation of the drying component 800 and extending the service life of the drying component 800.

[0335] In one possible implementation, referring to Fig.29 , Fig.30 and Fig.37 As shown, it also includes a base station 210, on which a water supply component 900 and a water distribution component 930 that are interconnected can be provided, and the water distribution component 930 has a first water outlet pipe 950 and a second water outlet pipe 960, and the water outlet end of the first water outlet pipe 950 and the water outlet end of the second water outlet pipe 960 are respectively located at different positions of the base station 210; when the cleaning body 100 is installed on the base station 210, one of the first water outlet pipe 950 and the second water outlet pipe 960 is connected to the cleaning body 100.

[0336] It should be noted that the water supply source in the embodiment of the present application can be connected to an external water source, which helps save space for installing a water replenishment device in the base station 210, thereby helping to reduce the volume of the base station 210 and achieve the function of replenishing water without a clean water tank in the base station 210. At the same time, it can achieve large-volume cleaning of the cleaning body 100 and replenishment of the sewage tank 130, thereby improving the self-cleaning effect of the cleaning body 100 and the sewage tank 130.

In the embodiment of the present application, the first water outlet pipeline 950 may be connected to the cleaning body 100, and the second water outlet pipeline 960 may be connected to the base station 210. Alternatively, the settings may also be interchanged, that is, the first water outlet pipeline 950 may be connected to the base station 210, and the second water outlet pipeline 960 may be connected to the cleaning body 100. This is not limited in the present embodiment.

[0338] In the embodiment of the present application, in actual application, the cleaning body 100 includes a floor brush 142 , and one of the first water outlet pipe 950 and the second water outlet pipe 960 is connected to the water divider on the floor brush 142 .

This helps to achieve a large amount of water spraying on the floor brush 142, thereby achieving a large amount of water cleaning of the cleaning body 100 and water replenishment of the sewage tank 130, thereby improving the self-cleaning effect of the cleaning body 100 and the sewage tank 130.

[0340] It should be noted that in the embodiment of the present application, while spraying water, the main motor 110 can continuously perform suction, and at the same time the sewage outlet 133 of the sewage tank 130 is opened, so that the effect of spraying water, suction and surge can be achieved, thereby maximizing the self-cleaning effect of the sewage tank 130.

When the cleaning body 100 is installed on the base station 210, the water outlet end of the first water outlet pipeline 950 and the water outlet end of the second water outlet pipeline 960 are respectively located on opposite sides of the cleaning body 100. In this way, in the actual water spraying process, the two water replenishment waterways can spray water from opposite sides of the cleaning body 100 toward the cleaning body 100 at the same time, which is helpful to realize a large amount of water spraying on the floor brush 142, and then realize a large amount of water cleaning of the cleaning body 100 and water replenishment of the sewage tank 130, and improve the self-cleaning effect of the sewage tank 130 and the cleaning body 100.

[0343] It should be noted that the water outlet end of the first water outlet pipe 950 and the water outlet end of the second water outlet pipe 960 are respectively located on opposite sides of the cleaning body 100. This arrangement helps to spray water at multiple positions of the cleaning body 100, thereby ensuring the cleaning effect of the cleaning body 100 to the greatest extent.

[0344] In one possible implementation, referring to Fig.38 As shown, the directions of the water outlet ends of the first water outlet pipe 950 and the second water outlet pipe 960 can be tilted upward relative to the main body installation surface 290. In this way, the water spraying direction is toward the cleaning body 100, thereby further ensuring a large amount of water cleaning for the cleaning body 100 and water replenishment for the sewage tank 130, thereby improving the self-cleaning effect of the sewage tank 130 and the cleaning body 100.

[0345] In one possible implementation, continue to refer to Fig.38As shown, the angle between the direction of the water outlet end of the first water outlet pipe 950 and the direction of the water outlet end of the second water outlet pipe 960 and the main body mounting surface 290 can be greater than 0° and less than 90°.
