Description

Technical Field

[0001] The present disclosure belongs to the field of cleaning equipment, and specifically provides a control method for a cleaning system. Background Art

[0002] A surface cleaning device is a household tool used to help users clean a room. The existing surface cleaning device comprises a mop, a clean water tank and a liquid supply pump connected to the clean water tank. The surface cleaning device can use the mop to mop and clean the surface to be cleaned, and the liquid supply pump can transport the cleaning liquid in the clean water tank to the mop or the surface to be cleaned to improve the cleaning effect.

[0003] However, the cleaning liquid in the clean water tank needs to flow through the liquid supply pump, and the structure of the liquid supply pump is relatively complicated. When the cleaning liquid in the clean water tank is used up, some cleaning liquid that cannot be discharged will accumulate in the liquid supply pump. If not used for a long time, the cleaning liquid accumulated in the liquid supply pump is prone to deterioration, resulting in secondary contamination of the surface to be cleaned when used again. Summary of the invention

[0004] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem of secondary contamination of the cleaning surface caused by the accumulation of cleaning liquid in the liquid supply pump, the present disclosure provides a control method for a cleaning system, wherein the cleaning system comprises a surface cleaning device and a cleaning assembly, wherein the surface cleaning device comprises a body and a wiping member located at the bottom of the body, wherein the surface cleaning device further comprises a liquid storage assembly and an air pump, wherein the liquid storage assembly is provided with a liquid outlet cavity and a liquid outlet pipe, wherein the liquid outlet cavity is respectively connected to the air outlet of the air pump and the liquid outlet pipe; and the control method comprises:

[0005] Liquid supply step: start the air pump to supply the cleaning liquid in the liquid outlet cavity to the mopping member or the surface to be cleaned through the liquid outlet pipe.

[0006] Optionally, the surface cleaning device placed in the cleaning assembly is in a self-cleaning state when performing the liquid supply step, so as to clean the mopping member using the cleaning liquid supplied by the liquid storage assembly.

[0007] Optionally, the surface cleaning device separated from the cleaning component is in a cleaning state when performing the liquid supply step, so as to clean the surface to be cleaned using the cleaning liquid supplied by the liquid storage component.

[0008] Optionally, the cleaning component is provided with a clean liquid cavity, and the liquid storage component is further provided with a liquid inlet cavity and a liquid inlet pipe, and the liquid inlet cavity is respectively connected with the air suction port of the air pump and the liquid inlet pipe;

[0009] The aforementioned control method further includes:

[0010] Liquid aspiration step: starting the aforementioned air pump to aspirate the cleaning liquid in the aforementioned clean liquid cavity into the aforementioned liquid inlet cavity through the aforementioned liquid inlet pipe.

[0011] Optionally, in the aforementioned liquid supply step, at the same time or after the aforementioned air pump sucks the liquid, the cleaning liquid in the aforementioned liquid outlet cavity is supplied to the aforementioned mopping member or the surface to be cleaned through the aforementioned liquid outlet pipe.

[0012] Optionally, an air relief valve is connected between the liquid inlet cavity and the liquid outlet cavity, and the air relief valve can be selectively opened or closed to balance the air pressure in the liquid inlet cavity and the liquid outlet cavity, and a control valve for controlling the flow of liquid is provided between the liquid inlet cavity and the liquid outlet cavity;

[0013] The aforementioned liquid aspirating step and the aforementioned liquid supplying step further include: closing the aforementioned air release valve and the aforementioned control valve;

[0014] The aforementioned control method further includes:

[0015] Liquid balancing step: stop the air pump, open the air relief valve, and open the control valve to allow the liquid in the liquid inlet chamber to flow into the liquid outlet chamber.

[0016] Optionally, the liquid storage assembly further comprises a liquid level detection device for detecting whether the liquid inlet cavity is full of cleaning liquid.

[0017] The aforementioned liquid absorbing step also includes: when the aforementioned liquid level detection device detects that the aforementioned liquid inlet cavity is full of cleaning liquid, stopping the aforementioned air pump from working.

[0018] Optionally, the liquid level detection device is a first float disposed in the liquid inlet cavity, and the first float can block the communication between the liquid inlet cavity and the air pump;

[0019] When the liquid level detection device detects that the liquid inlet cavity is full of cleaning liquid, the air pump is stopped, including:

[0020] When it is detected that the working current of the air pump increases to a preset threshold value, it is determined that the first float rises to a position blocking the air outlet, so that the air pump stops working.

[0021] Optionally, the liquid level detection device comprises a second float arranged in the liquid inlet cavity, a conductor arranged on the second float, and a positive electrode and a negative electrode arranged on the top of the liquid inlet cavity;

[0022] When the liquid level detection device detects that the liquid inlet cavity is full of cleaning liquid, the air pump is stopped, including:

[0023] When it is detected that the positive electrode and the negative electrode are conducting, the air pump is stopped.

[0024] Optionally, the surface cleaning device further comprises a sewage box for collecting the dirty liquid on the mopping member, and a liquid level detection component is provided in the sewage box;

[0025] The liquid supplying step comprises: after the liquid level detecting component detects that the sewage box is full, stopping the wiping member from working.

[0026] It can be understood by those skilled in the art that the control method of the cleaning system disclosed above has at least the following beneficial effects:

[0027] The air pump can transport air into the liquid outlet cavity, thereby utilizing the pressure generated by the enclosed air in the liquid outlet cavity to push the cleaning liquid in the liquid outlet cavity through the liquid outlet pipe to supply it to the mopping member or the surface to be cleaned, so that the liquid supply flow channel between the liquid outlet cavity and the supply point does not need to be provided with a power device for accelerating the cleaning liquid, and a liquid outlet pipe with a simple structure can be provided, so that it is not easy for cleaning liquid to accumulate in the liquid supply flow channel. Moreover, after the cleaning liquid in the liquid outlet cavity is used up, the air pressure can continue to act on the liquid outlet pipe until the cleaning liquid is completely squeezed out, further avoiding the accumulation of cleaning liquid in the liquid supply flow channel.

[0028] Furthermore, the air pump can not only suck the cleaning liquid in the clean liquid cavity into the liquid inlet cavity through the liquid inlet pipe, but also supply the cleaning liquid in the liquid outlet cavity to the mopping member or the surface to be cleaned through the liquid outlet pipe, that is, the liquid replenishment and liquid supply work are realized at the same time by using one air pump, so that the main structures of liquid replenishment and liquid supply are concentrated in the surface cleaning device, and then the electric control systems of liquid replenishment and liquid supply are concentrated in the surface cleaning device, and there is no need to set a water replenishment pump and related electric control systems on the cleaning component, which simplifies the system structure. Moreover, using one air pump to realize liquid supply and liquid replenishment can reduce the volume of the entire system or allow the cleaning component to have more space to store cleaning liquid.

[0029] Furthermore, when the liquid outlet chamber supplies liquid to the mopping and wiping member, the liquid outlet chamber supplies the most cleaning liquid to the mopping and wiping member for the first time. As the cleaning liquid in the liquid inlet chamber decreases, the cleaning liquid subsequently entering the liquid outlet chamber will decrease in sequence, so that the cleaning liquid that the liquid outlet chamber can supply to the mopping and wiping member will also decrease in sequence. Because the mopping and wiping member is relatively dry at the beginning, the maximum amount of cleaning liquid supplied by the liquid outlet chamber for the first time can effectively soak the mopping and wiping member, and the mopping and wiping member is relatively wet subsequently. The cleaning liquid supplied by the liquid outlet chamber to the mopping and wiping member decreases in sequence, which can prevent the mopping and wiping member from being too wet, causing water stains to remain on the surface to be cleaned.

[0030] Furthermore, by providing a liquid level detection device in the liquid inlet cavity, the air pump can be stopped when the liquid level detection device detects that the liquid inlet cavity is full of cleaning liquid, thereby providing feedback to the user when the liquid inlet cavity is full, thereby improving the user experience. At the same time, it can reduce unnecessary air pump working time and improve the endurance of the surface cleaning device. In addition, since both the air pump and the liquid level detection device are provided on the surface cleaning device, it is easier to integrate the air pump and the liquid level detection device into the same electronic control system than to provide a water replenishment pump separately in the cleaning component, thereby facilitating the control of the air pump.

[0044] The present disclosure provides a control method for a cleaning system, which includes a surface cleaning device and a cleaning component. The surface cleaning device includes a body and a wiping member located at the bottom of the body. The surface cleaning device also includes a liquid storage component and an air pump. The liquid storage component is provided with a liquid outlet cavity and a liquid outlet pipe, and the liquid outlet cavity is respectively connected to the air outlet and the liquid outlet pipe of the air pump.

[0045] Furthermore, the control method disclosed in the present invention comprises: a liquid supply step: starting the air pump to supply the cleaning liquid in the liquid outlet cavity to the mopping member or the surface to be cleaned through the liquid outlet pipe.

[0046] The present invention enables an air pump to transport air into the liquid outlet cavity, thereby utilizing the pressure generated by the enclosed air in the liquid outlet cavity to push the cleaning liquid in the liquid outlet cavity to be supplied to the mopping member or the surface to be cleaned through the liquid outlet pipe, so that the liquid supply channel between the liquid outlet cavity and the supply point does not need to be provided with a power device for accelerating the cleaning liquid, and only a liquid outlet pipe with a simple structure is required, so that it is not easy for the cleaning liquid to accumulate in the liquid supply channel. Moreover, after the cleaning liquid in the liquid outlet cavity is used up, the air pressure can continue to act on the liquid outlet pipe until all the cleaning liquid is squeezed out, further avoiding the cleaning liquid from accumulating in the liquid supply channel.

[0047] The control method of the cleaning system of the present disclosure will be described below with reference to the accompanying drawings.

[0048] The first embodiment of the present disclosure:

[0049] First refer to Figures 1 to 5 The main structures of the surface cleaning device 1 and the cleaning assembly 2 in this embodiment are described in detail.

[0050] like Figure 1 As shown, the surface cleaning device 1 can be placed on a cleaning component 2, and the cleaning component 2 is used to clean the surface cleaning device 1 and replenish cleaning liquid (clean water or detergent).

[0051] like Figure 2 As shown, the surface cleaning device 1 includes a body 11, a handle 12, a mopping member 13, a liquid storage assembly 14, an air pump 15 and a dirt collection box 16 (such as Figure 5 As shown). The handle 12 is pivotally connected to the body 11, and the user can hold the handle 12 to operate the surface cleaning device 1 and control the surface cleaning device 1 to perform cleaning work. The mopping member 13 is arranged on the bottom side of the body 11, and is used to mop and clean the surface to be cleaned. The liquid storage component 14 is used to store cleaning liquid. The air pump 15 is connected to the liquid storage component 14, and can suck the external cleaning liquid into the liquid storage component 14, and can supply the cleaning liquid in the liquid storage component 14 to the mopping member 13 or the surface to be cleaned. The dirt collection box 16 is used to receive the dirty liquid on the mopping member 13.

[0052] It should be noted that the liquid storage assembly 14 can be disposed on the handle 12 or on the top of the body 11 .

[0053] like Figure 3 As shown, the liquid storage assembly 14 includes a liquid inlet chamber 141 and a liquid outlet chamber 142. The liquid inlet chamber 141 is provided with a liquid inlet hole 1411 and an air outlet hole 1412, and the liquid outlet chamber 142 is provided with an air inlet hole 1421 and a liquid outlet hole 1422. A control valve 143 is provided between the liquid inlet chamber 141 and the liquid outlet chamber 142, and the control valve 143 can control the communication between the liquid inlet chamber 141 and the liquid outlet chamber 142.

[0054] Return to reference Figure 1and Figure 2 Specifically, the air suction port 151 of the air pump 15 is connected to the air outlet hole 1412 of the liquid inlet chamber 141 through an air suction pipe (not marked in the figure), so as to be in fluid communication with the liquid inlet chamber 141, and the air outlet 152 of the air pump 15 is connected to the air inlet hole 1421 of the liquid outlet chamber 142 through an air supply pipe (not marked in the figure), so as to be in fluid communication with the liquid outlet chamber 142. The liquid inlet hole 1411 of the liquid inlet chamber 141 is connected to the liquid inlet pipe 17, so that the cleaning liquid is sucked into the liquid inlet chamber 141 through the liquid inlet pipe 17, and the liquid outlet hole 1422 of the liquid outlet chamber 142 is connected to the liquid outlet pipe 18, so that the cleaning liquid in the liquid outlet chamber 142 is supplied to the mopping member 13 or the surface to be cleaned through the liquid outlet pipe 18.

[0055] Continue to refer to Figure 1 and Figure 2 Further, a relief valve 19 is provided between the air extraction pipeline and the air supply pipeline, and a control valve 143 (such as Figure 3 141 and the outlet chamber 142 are connected to the outside world. After the air relief valve 19 is opened, the inlet chamber 141 and the outlet chamber 142 are both connected to the outside world to balance the air pressure of the two, so that the control valve 143 is opened under the gravity of the liquid in the inlet chamber 141, and the cleaning liquid in the inlet chamber 141 flows into the outlet chamber 142 (for example, from Figure 1 The cleaning liquid in the liquid inlet chamber 141 and the liquid outlet chamber 142 is in a state of Figure 2 The cleaning liquid state in the liquid inlet chamber 141 and the liquid outlet chamber 142 is shown).

[0056] It should be noted that the control valve 143 may also be an electrically controlled valve such as a solenoid valve, thereby not requiring pressure to open it.

[0057] like Figure 4 As shown, the cleaning component 2 includes a cleaning tank 21 and a clean liquid chamber 22. Cleaning ribs 23 are provided in the cleaning tank 21. The cleaning tank 21 is used to accommodate the wiping member 13 of the surface cleaning device 1. The wiping member 13 can use the cleaning ribs 23 in the cleaning tank 21 to scrape and clean. The clean liquid chamber 22 can store cleaning liquid. The clean liquid chamber 22 is provided with an external pipe 24. The liquid storage component 14 can be connected to the clean liquid chamber 22 through the external pipe 24. The turned-on air pump 15 can suck the cleaning liquid in the clean liquid chamber 22 into the liquid storage component 14. Preferably, the cleaning component 2 is provided with a positioning column (not marked in the figure), and the surface cleaning device 1 is provided with a corresponding positioning hole, so as to position the assembly between the surface cleaning device 1 and the cleaning component 2.

[0058] Return to reference Figure 1 and Figure 2The surface cleaning device 1 is placed on the cleaning component 2. After being placed in place, the liquid inlet pipe 17 and the external pipe 24 are connected together, so that the liquid inlet chamber 141 and the clean liquid chamber 22 are connected, and the cleaning liquid in the clean liquid chamber 22 can be sucked into the liquid inlet chamber 141.

[0059] like Figure 1 As shown, the liquid outlet pipe 18 is provided with a liquid outlet pressure valve 3, and the opening pressure of the liquid outlet pressure valve 3 is greater than or equal to the pressure generated by the full liquid volume of the liquid outlet chamber 142, that is, the liquid outlet pressure valve 3 can be opened only under the additional pressure of the air pump 15, thereby preventing the liquid outlet chamber 142 from leaking. In addition, the liquid inlet pipe 17 is provided with a liquid inlet check valve 4 at one end away from the liquid inlet chamber 141 (i.e., the joint with the external pipe 24), which can prevent the cleaning liquid retained in the liquid inlet pipe from dripping compared to the one set in the middle of the liquid inlet pipe.

[0060] like Figure 1 and Figure 3 As shown, the liquid inlet cavity 141 has a first float 5 as a liquid level detection device. The first float 5 floats up as the liquid level in the liquid inlet cavity 141 rises, and finally floats to a position where the air outlet 1412 is blocked (such as Figure 1 ), so that the current of the air pump 15 increases, and when it is detected that the working current of the air pump 15 increases to a preset threshold, the air pump 15 stops working. A limiting structure (not marked in the figure) is provided in the liquid inlet cavity 141 to limit the floating path of the first float 5, so that the first float 5 can accurately block the air outlet 1412.

[0061] like Figure 5 As shown, a liquid level detection component consisting of a first electrode 161 and a second electrode 162 is provided on the top of the dirt collecting box 16 of the surface cleaning device 1. When the liquid level in the dirt collecting box 16 submerges the first electrode 161 and the second electrode 162, the first electrode 161 and the second electrode 162 can be turned on. When it is detected that the first electrode 161 and the second electrode 162 are turned on, the wiping member 13 stops rotating and a reminder is given to the user.

[0062] It should be noted that the liquid inlet chamber 141 can also use the same liquid level detection method as the dirt collecting box 16, that is, two electrodes are set on the top of the liquid inlet chamber 141, and when the liquid in the liquid inlet chamber 141 submerges and conducts the two electrodes, the air pump 15 stops working.

[0063] Refer to the following Figure 1-Figure 5 The control method of the cleaning system in this embodiment is described in detail.

[0064] The control method of this embodiment includes a liquid supply step, an optional liquid aspiration step and an optional liquid balance step.

[0065] The liquid supply step includes: starting the air pump 15 to supply the cleaning liquid in the liquid outlet cavity 142 to the mopping member 13 or the surface to be cleaned through the liquid outlet pipe 18 .

[0066] Specifically, the liquid outlet cavity 142 is connected to the air outlet 152 of the air pump 15 and the liquid outlet pipe 18 respectively. The air of the turned-on air pump 15 is delivered to the liquid outlet cavity 142, so that the pressure in the liquid outlet cavity 142 increases. As the pressure in the liquid outlet cavity 142 continues to increase, it exceeds the opening pressure of the liquid outlet pressure valve 3, and the liquid outlet pressure valve 3 opens under the pressure, and the cleaning liquid in the liquid outlet cavity 142 flows to the mopping member 13 or the surface to be cleaned (such as Figure 2 (indicated by the flow arrows).

[0067] Furthermore, before the air pump 15 is turned on and during its operation, the liquid supply step also includes: closing the air relief valve 19 and the control valve 143 to prevent the pressure in the liquid outlet chamber 142 from failing to increase, and to prevent the cleaning liquid in the liquid outlet chamber 142 from flowing into the liquid inlet chamber 141, so that the air pump 15 supplies the cleaning liquid in the liquid outlet chamber 142 to the mopping member 13 or the surface to be cleaned.

[0068] Among them, closing the air release valve 19 includes: the air release valve 19 is controlled to open and close by the user, and before the air pump 15 is turned on, the user closes the air release valve 19 so that the air release valve 19 is closed during the operation of the air pump 15; or, the air release valve 19 is automatically closed, for example, the air release valve 19 is set with a preset opening time to allow the cleaning liquid in the liquid inlet chamber 141 to enter the liquid outlet chamber 142, and after the preset opening time is reached, the air release valve 19 is automatically closed, so that the air release valve 19 is closed during the operation of the air pump 15.

[0069] Furthermore, the control valve 143 is closed: as an example 1, when the control valve 143 is a one-way pressure valve arranged between the liquid inlet chamber 141 and the liquid outlet chamber 142, when the air pump 15 supplies the cleaning liquid in the liquid storage assembly 14 to the mopping member 13 or the surface to be cleaned, the turned-on air pump 15 conveys air to the liquid outlet chamber 142, so that the pressure in the liquid outlet chamber 142 is higher, and the control valve 143 is closed under the action of the pressure.

[0070] As a second example, when the control valve 143 is a solenoid valve disposed between the liquid inlet chamber 141 and the liquid outlet chamber 142, the solenoid valve is in a closed state when the cleaning liquid in the liquid storage assembly 14 is supplied to the mopping member 13 or the surface to be cleaned.

[0071] Furthermore, during the operation of the air pump 15, the liquid supply step further includes: after the liquid level detection component detects that the sewage box 16 is full, the wiping member 13 stops working.

[0072] Specifically, a liquid level detection component consisting of a first electrode 161 and a second electrode 162 is provided on the top of the dirt collecting box 16. When the liquid level in the dirt collecting box 16 submerges the first electrode 161 and the second electrode 162, the first electrode 161 and the second electrode 162 can be turned on. When it is detected that the first electrode 161 and the second electrode 162 are turned on, the wiping member 13 stops rotating and a reminder is issued to the user.

[0073] In addition, depending on whether the surface cleaning device 1 is placed in the cleaning component 2, the surface cleaning device 1 has a self-cleaning state and a cleaning state when performing the liquid supply step. The surface cleaning device 1 placed in the cleaning component 2 is in the self-cleaning state when performing the liquid supply step, that is, the cleaning liquid in the liquid outlet cavity 142 is supplied to the mopping member 13 or the cleaning tank 21, thereby cleaning the mopping member 13; the surface cleaning device 1 separated from the cleaning component 2 is in the cleaning state when performing the liquid supply step, that is, the cleaning liquid in the liquid outlet cavity 142 is supplied to the mopping member 13 or the surface to be cleaned, thereby cleaning the surface to be cleaned.

[0074] The liquid suction step includes: starting the air pump 15 to suck the cleaning liquid in the clean liquid chamber 22 into the liquid inlet chamber 141 through the liquid inlet pipe 17 .

[0075] Specifically, the liquid inlet chamber 141 is connected to the air suction port 151 of the air pump 15 and the liquid inlet pipe 17 respectively. The cleaning liquid is filled in the clean liquid chamber 22 of the cleaning component 2, and the surface cleaning device 1 is placed on the cleaning component 2. After being placed in place, the liquid inlet pipe 17 is connected to the external pipe 24, so that the clean liquid chamber 22 of the liquid inlet chamber 141 is connected. The turned-on air pump 15 draws away the air in the liquid inlet chamber 141, so that the vacuum degree of the liquid inlet chamber 141 increases. As the vacuum degree in the liquid inlet chamber 141 increases, the cleaning liquid in the clean liquid chamber 22 is drawn into the liquid inlet chamber 141 through the external pipe 24, the liquid inlet pipe 17 and the liquid inlet hole 1411 (such as Figure 1 (indicated by the flow arrows).

[0076] Furthermore, before the air pump 15 is turned on and during its operation, the liquid suction step also includes: closing the air relief valve 19 and the control valve 143 to increase the vacuum degree of the liquid inlet chamber 141 , and the air pump 15 sucks the cleaning liquid in the clean liquid chamber 22 into the liquid inlet chamber 141 .

[0077] After the surface cleaning device 1 is placed on the cleaning assembly 2, the air release valve 19 is in a closed state.

[0078] Furthermore, close the control valve 143: as example one, when the control valve 143 is a one-way pressure valve arranged between the liquid inlet chamber 141 and the liquid outlet chamber 142, the control valve 143 is in a closed state before the air pump 15 is turned on. When the air pump 15 sucks the external cleaning liquid into the liquid storage component 14, the turned-on air pump 15 transports air to the liquid outlet chamber 142, and the one-way pressure valve is closed under the action of pressure.

[0079] As a second example, when the control valve 143 is a solenoid valve disposed between the liquid inlet chamber 141 and the liquid outlet chamber 142 , the solenoid valve is in a closed state before the air pump 15 is turned on and when the air pump 15 sucks the external cleaning liquid into the liquid storage assembly 14 .

[0080] Furthermore, during the operation of the air pump 15 , the liquid suction step further includes: when the liquid level detection device detects that the liquid inlet cavity 141 is full of cleaning liquid, the air pump 15 stops working.

[0081] As an example 1, when the liquid level detection device is the first float 5, as the liquid level in the liquid inlet cavity 141 rises, the first float 5 gradually floats up. When the liquid inlet cavity 141 is full of cleaning liquid, the first float 5 floats up to a position where the air outlet 1412 is blocked (such as Figure 1 When it is detected that the working current of the air pump 15 increases to a preset threshold, it is determined that the liquid inlet cavity 141 is full of cleaning liquid, and the air pump 15 stops working.

[0082] As a second example, when the liquid level detection device is a positive electrode and a negative electrode disposed at the top of the liquid inlet cavity 141, when the liquid inlet cavity 141 is filled with cleaning liquid, the positive electrode and the negative electrode are submerged in the cleaning liquid and are connected. When it is detected that the positive electrode and the negative electrode are connected, it is determined that the liquid inlet cavity 141 is filled with cleaning liquid, and the air pump 15 stops working.

[0083] It should be noted that the liquid supply step can be performed while the air pump 15 is sucking liquid. For example, when the surface cleaning device 1 is placed in the cleaning component 2, there is still some unused residual liquid in the liquid outlet chamber 142. At this time, the air pump 15 is turned on to suck liquid, and the residual liquid in the liquid outlet chamber 142 will be supplied to the mopping member 13 or the cleaning tank 21 at the same time. Alternatively, the cleaning liquid in the liquid inlet chamber 141 is allowed to enter the liquid outlet chamber 142, and then the air pump 15 is turned on. The air pump 15 can suck the cleaning liquid in the clean liquid chamber 22 into the liquid inlet chamber 141 and can also supply the cleaning liquid in the liquid outlet chamber 142 to the mopping member 13 or the cleaning tank 21. After the liquid is sucked, the liquid supply step can also be performed separately. For example, after the liquid inlet chamber 142 is filled, the surface cleaning device 1 is removed from the cleaning component 2, so that the cleaning liquid in the liquid inlet chamber 141 enters the liquid outlet chamber 142, and then the air pump 15 is turned on. The air pump 15 supplies the cleaning liquid in the liquid outlet chamber 142 to the mopping member 13 or the surface to be cleaned.

[0084] The liquid balancing step includes: stopping the air pump 15 , opening the air relief valve 19 , and opening the control valve 143 to allow the liquid in the liquid inlet chamber 141 to flow into the liquid outlet chamber 142 .

[0085] It can be understood by those skilled in the art that stopping the air pump 15 in the liquid balancing step includes receiving a user's instruction to stop the air pump 15, or stopping the air pump 15 when it is detected that the cleaning liquid in the liquid outlet chamber 142 is used up, or stopping the air pump 15 when it is detected that the liquid inlet chamber 141 is full.

[0086] Specifically, as example one, when the control valve 143 is a one-way pressure valve, the air relief valve 19 is opened, so that the liquid inlet chamber 141 and the liquid outlet chamber 142 are both connected to the outside, so that the air pressure between the liquid inlet chamber 141 and the liquid outlet chamber 142 reaches a balance, so that the control valve 143 is opened under the action of the gravity of the liquid inlet chamber 141, and the cleaning liquid in the liquid inlet chamber 141 flows into the liquid outlet chamber 142 until the liquid levels are equal.

[0087] As example 2, when the control valve 143 is a solenoid valve, the air relief valve 19 is opened so that the liquid inlet chamber 141 and the liquid outlet chamber 142 are connected to the outside world, so that the air pressure between the liquid inlet chamber 141 and the liquid outlet chamber 142 reaches a balance, the solenoid valve is opened, and the cleaning liquid in the liquid inlet chamber 141 flows into the liquid outlet chamber 142 until the liquid levels are equal.

[0088] Those skilled in the art can understand that the air pump 15 can transport air into the liquid outlet chamber 142, thereby using the pressure generated by the enclosed air in the liquid outlet chamber 142 to push the cleaning liquid in the liquid outlet chamber 142 through the liquid outlet pipe 18 to be supplied to the mopping member 13 or the surface to be cleaned, so that the liquid supply channel between the liquid outlet chamber 142 and the supply point does not need to be provided with a power device for accelerating the cleaning liquid, and a liquid outlet pipe 18 with a simple structure can be provided, so that it is not easy for cleaning liquid to accumulate in the liquid supply channel. Moreover, after the cleaning liquid in the liquid outlet chamber 142 is used up, the air pressure can continue to act on the liquid outlet pipe 18 until the cleaning liquid is completely squeezed out, further avoiding the accumulation of cleaning liquid in the liquid supply channel. Furthermore, the air pump 15 can not only suck the cleaning liquid in the clean liquid cavity 22 into the liquid inlet cavity 141 through the liquid inlet pipe 17, but also supply the cleaning liquid in the liquid outlet cavity 142 to the mopping member 13 or the surface to be cleaned through the liquid outlet pipe 18, that is, the air pump 15 is used to simultaneously realize the liquid replenishment and liquid supply work, so that the main structures of the liquid replenishment and liquid supply are concentrated in the surface cleaning device 1, and then the electric control system of the liquid replenishment and liquid supply is concentrated in the surface cleaning device 1, and there is no need to set a water replenishment pump and related electric control system on the cleaning component 2, which simplifies the system structure. Moreover, using an air pump 15 to realize liquid supply and liquid replenishment can reduce the volume of the entire system or allow the cleaning component 2 to have more space to store cleaning liquid.

[0089] Furthermore, when the liquid outlet chamber 142 supplies liquid to the mopping and wiping member 13, the liquid outlet chamber 142 supplies the most cleaning liquid to the mopping and wiping member 13 for the first time. As the cleaning liquid in the liquid inlet chamber 141 decreases, the cleaning liquid that subsequently enters the liquid outlet chamber 142 will decrease successively, so that the cleaning liquid that the liquid outlet chamber 142 can supply to the mopping and wiping member 13 will also decrease successively. Because the mopping and wiping member 13 is relatively dry at the beginning, the liquid outlet chamber 141 supplies the maximum amount of cleaning liquid for the first time, which can effectively soak the mopping and wiping member, and the mopping and wiping member 13 is relatively wet subsequently. The cleaning liquid supplied to the mopping and wiping member 13 by the liquid outlet chamber 142 decreases successively, which can prevent the mopping and wiping member 13 from being too wet, causing water stains to remain on the surface to be cleaned.

[0090] Furthermore, by arranging the first float 5 in the liquid inlet chamber 141, the first float 5 can float up as the liquid level in the liquid inlet chamber 141 increases until the air outlet 1412 of the liquid inlet chamber 141 is blocked, thereby increasing the current of the air pump 15. When it is detected that the working current of the air pump 15 increases to a preset threshold value, the air pump 15 stops working. Furthermore, when the liquid inlet chamber 141 is filled with cleaning liquid, the air pump 15 stops working to give feedback to the user, thereby improving the user experience. At the same time, it can reduce unnecessary working time of the air pump 15 and improve the battery life of the surface cleaning device 1.

[0091] The second embodiment of the present disclosure:

[0092] like Figure 6 As shown, different from the first embodiment, in this embodiment, a liquid level detection device composed of a second float 6, a conductor 7, and a positive electrode and a negative electrode (not marked in the figure) fixed on the top of the liquid inlet cavity 141 is used to detect the liquid level in the liquid inlet cavity 141. Among them, the conductor 7 is arranged on the second float 6, and the second float 6 is located in the liquid inlet cavity 141 and floats up with the increase of the liquid level in the liquid inlet cavity 141. When the second float 6 floats to a position where it contacts the positive electrode and the negative electrode, the conductor 7 on the second float 6 conducts the positive electrode and the negative electrode. When it is detected that the positive electrode and the negative electrode are conducting, the air pump 15 stops working.

[0093] The third embodiment of the present disclosure:

[0094] like Figure 7 As shown, different from the second embodiment, the present embodiment uses a liquid level detection device composed of a third float 8, a magnet 9 and a reed switch (not marked in the figure) fixed on the top of the liquid inlet chamber 141 to detect the liquid level in the liquid inlet chamber 141. The magnet 9 is arranged on the third float 8, the third float 8 is located in the liquid inlet chamber 141 and floats up with the increase of the liquid level in the liquid inlet chamber 141. When the third float 8 floats up to the position in contact with the reed switch, the reed switch is turned on by the magnetic field of the magnet 9. When it is detected that the reed switch is turned on, the air pump 15 stops working.

[0095] It should be noted that the dirt collecting box 16 may also use the liquid level detection device described in the second embodiment and the third embodiment.

[0096] It can be understood by those skilled in the art that, compared with separately providing a water replenishment pump in the cleaning component, providing both the air pump 15 and the liquid level detection device in the surface cleaning device 1 makes it easier to integrate the air pump 15 and the liquid level detection device in the same electronic control system, thereby facilitating the control of the air pump 15 and thus controlling the replenishment work.

[0097] The fourth embodiment of the present disclosure:

[0098] Although not shown in the figures, unlike the first, second and third embodiments, in this embodiment, no liquid level detection device is provided in the liquid inlet chamber 141. Instead, the operating time of the air pump 15 for extracting the cleaning liquid is directly set, so that the air pump 15 can fill the liquid inlet chamber 141 with cleaning liquid within the operating time and shut down after the operating time is reached.

[0099] The fifth embodiment of the present disclosure:

[0100] Although not shown in the figures, unlike the aforementioned embodiments, the present embodiment does not include a liquid level detection device in the liquid inlet chamber 141 and does not set a running time for extracting cleaning liquid. When the liquid inlet chamber 141 is filled with cleaning liquid, the air pump 15 continues to absorb the cleaning liquid, causing the cleaning liquid to enter the liquid outlet chamber 142 from the air pump 15, and then be supplied from the liquid outlet chamber 142 to the mopping member 13 or the cleaning tank 21, that is, while the air pump 15 is absorbing liquid, the liquid supply step is performed, and at the same time, the surface cleaning device 1 is in a self-cleaning state.

[0101] So far, the technical solutions of the present disclosure have been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present disclosure is not limited to these specific embodiments. Without departing from the technical principles of the present disclosure, those skilled in the art can split and combine the technical solutions in the above-mentioned various embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the present disclosure will fall within the protection scope of the present disclosure.
