Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0054] The current water transportation operation method of the floor scrubber is generally to manually add water to the machine body, empty the machine body, and clean the sewage tank after each use. The operation is cumbersome and inconvenient, which affects the floor scrubbing efficiency and wastes the user's time.

[0055] In order to solve the above problems, the present invention provides a new water circulation system for floor scrubbers, which can automatically add water, empty sewage and perform cleaning operations on the floor scrubber through a base station, thereby improving floor scrubbing efficiency and saving operator time. Figure 1 As shown, it includes: a base station 100 and a floor scrubber 200; the base station 100 includes a first clean water tank 101 and a first sewage tank 102; the floor scrubber 200 includes:

[0056] A first control valve 201 may be connected to the first clean water tank 101;

[0057] A second control valve 202 connected to the first control valve 201;

[0058] A second sewage tank 203 connected to the second control valve 202;

[0059] A garbage tank 205 connected to the second sewage tank 203;

[0060] The first control valve 201 is connected to the trash box 205 , and the trash box 205 can be connected to the first sewage tank 102 .

[0061] It is worth noting that the base station 100 is detachably connected to the floor scrubber 200. After the base station 100 is installed in a location, the floor scrubber 200 first connects to the base station 100 for automatic water addition, and then the floor scrubber 200 is separated from the base station 100, thereby performing a floor cleaning operation by the floor scrubber 200. In the present invention, by sequentially connecting the first control valve 201, the second control valve 202, the second sewage tank 203, and the trash bin 205, with the first control valve 201 connected to the first clean water tank 101 and the trash bin 205 connected to the first sewage tank 102, the base station 100 automatically adds water to the floor scrubber 200, automatically dumps sewage, and automatically cleans the floor, thereby improving work efficiency, reducing staff labor, and saving time.

[0062] Specifically, the water inlet end of the first control valve 201 is connected to the first clean water tank 101 of the base station 100. In this embodiment, the first clean water tank 101 contains clean water, but is not limited to this. It can contain cleaning liquid. In addition, the content of clean water in the first clean water tank 101 is sufficient. The connecting pipe between the first control valve 201 and the first clean water tank 101 may include a faucet, so that the first clean water tank 101 is a water reservoir connected to the faucet at this time; the clean water in the first clean water tank 101 is injected into the floor scrubber 200, and the floor scrubber 200 has a water storage capacity, that is, it includes a second clean water tank 207. Therefore, when the floor scrubber 200 is cleaning the floor, after the second clean water tank 207 is injected into the second clean water tank 207 through the first clean water tank 101, the base station 100 is separated from the floor scrubber 200, so that the second clean water tank 207 of the floor scrubber 200 itself sprays water on the roller brush 209, and the roller brush 209 cleans the floor to achieve the purpose of cleaning the floor and improve the cleaning efficiency.

[0063] In this embodiment, if Figure 1 or Figure 2 As shown, the second control valve 202 is a three-way valve, and the second control valve 202 can be connected to the outside.

[0064] Specifically, the second control valve 201 has two inlet ends and one water outlet end. One inlet end of the second control valve 202 (i.e., the water inlet end, which is in a normally open state) is connected to one water outlet end of the first control valve 201, and the other inlet end of the second control valve 202 is connected to the outside atmosphere. The inlet end of the second control valve 202 connected to the atmosphere is in a normally closed state. Therefore, when this end is in a normally closed state, the first pump body 206 is started to pump air, so that the second sewage tank 203 is in a negative pressure state, thereby discharging the sewage in the garbage tank 205 upward to the second sewage tank 203 and temporarily storing it. Therefore, when the floor scrubber is working, the sewage in the second sewage tank 203 cannot flow downward to the garbage tank 205, and when the normally closed end of the second control valve 202 is changed to normally open and enters the atmospheric pressure, the sewage in the second sewage tank 203 can flow downward to the garbage tank 205.

[0065] In this embodiment, if Figures 3 to 5 As shown, the second sewage tank 203 is located above the garbage tank 205 .

[0066] Specifically, when the normally closed end of the second control valve 202 is switched to normally open, atmospheric pressure enters the second sewage tank 203 , thereby causing the sewage temporarily stored in the sewage tank 203 to flow downward to the garbage tank 205 .

[0067] In this embodiment, the floor scrubber 200 further includes:

[0068] The first pump body 206 is connected to the first control valve 201 and the second control valve 202 respectively;

[0069] The first pump body 206 is connected to the trash box 205 .

[0070] Specifically, the first pump body 206 is an air pump, which is connected to the normally open water inlet end of the second control valve 202 through the first pump body 206. When the first pump body 206 is started, the normally closed water outlet end of the second control valve 202 is in a closed state to form a sealed state, thereby generating a negative pressure inside the second sewage tank 203, thereby being able to pump the sewage in the garbage tank 205 connected to the second sewage tank 203 into the second sewage tank 203 located above; and the first pump body 206 is also connected to the normally open water outlet end of the first control valve 201, that is, the pipeline of the normally open water outlet end of the first control valve 201 is divided into two, and is connected to the first control valve 201 through the first pump body 206, so that the water in the first clean water tank 101 of the base station 100 can be directly transported to the garbage tank 205 through the first pump body 206, thereby achieving cleaning of the interior of the garbage tank 205, improving work efficiency, and eliminating the need for an operator to manually clean the garbage tank 205.

[0071] In this embodiment, the floor scrubber 200 further includes:

[0072] The two-way valve 204 connects the garbage tank 205 and the second sewage tank 203 .

[0073] Specifically, the garbage bin 205 is connected to the second sewage tank 203 through the two-way valve 204, so that the sewage in the garbage bin 205 is pumped into the second sewage tank 203, or the sewage in the second sewage tank 203 flows downward into the garbage bin 205. In addition, after the two-way valve 204 is closed, the garbage bin 205 and the second sewage tank 203 are isolated to prevent the second sewage tank 203 in a clean state from being contaminated by the garbage bin 205 being cleaned.

[0074] In this embodiment, the first control valve 201 is a three-way valve; the floor scrubber 200 further includes:

[0075] A second clean water tank 207 connected to the first control valve 201;

[0076] A roller brush 209 is connected to the second clean water tank 207;

[0077] The roller brush 209 is connected to the trash can 205 .

[0078] Specifically, if Figure 1As shown, the first control valve 201 has an inlet end and two outlet ends, one of which is normally open and is connected to the normally open inlet end of the second control valve 202 and the first pump body 206 respectively, and the other outlet end is normally closed and is connected to the second clean water tank 207. The second clean water tank 207 can store a certain amount of clean water required for floor cleaning. The water inlet end of the first control valve 201 is connected to the first clean water tank 101. When the normally closed water outlet end is changed to a normally open state, water is injected into the second clean water tank 207 through the base station 100 to realize automatic water injection operation; and the water in the second clean water tank 207 can be directly input into the roller brush 209, so that when the floor scrubber 200 cleans the floor, the clean water in the second clean water tank 207 is sprayed onto the roller brush 209, and the roller brush 209 rotates to clean the floor, so that the sewage on the roller brush 209 flows back to the garbage bin 205.

[0079] In this embodiment, the floor scrubber 200 further includes:

[0080] The second pump body 208 is connected to the second clean water tank 207 and the roller brush 209 .

[0081] Specifically, when the washing machine 200 cleans the floor, the clean water in the second clean water tank 207 is pumped to the roller brush through the second pump body 208 (ie, the water pump) to clean the floor.

[0082] In this embodiment, the base station 100 further includes:

[0083] The third pump body 103 is connected to the first clean water tank 207 and the first control valve 201 .

[0084] Specifically, the first clean water tank 101 is connected to the first control valve 201 through the third pump body 103 (i.e., the water pump), and the garbage bin 205 is connected to the first sewage tank 102, so as to realize the connection between the base station 100 and the floor scrubber 200. The clean water in the first cleaning tank 101 is directly transported to the garbage bin 205 for cleaning through the third pump body 103, or is sequentially input into the second sewage tank 203 and the garbage bin 205 for cleaning, or is transported to the second clean water tank 207 for filling the floor scrubber.

[0085] In this embodiment, if Figure 1 、 Figure 2 or Figure 4 As shown, the floor scrubber 200 includes:

[0086] Body shell 210;

[0087] A scrubbing housing 220 connected to the body housing 210;

[0088] The second sewage tank 203 and the second clean water tank 207 are located in the handle housing 210 , and the trash bin 205 is located in the scrubbing housing 220 .

[0089] Specifically, a nozzle 221 is provided above the roller brush 209, so that clean water is sprayed toward the roller brush 209 through the nozzle 221 by the second water pump 208; the second sewage tank 203 is provided with an inlet and outlet nozzle 212 connected to the second control valve 202, and the second sewage tank 203 is provided with a spray 211 connected to the inlet and outlet nozzle 212, so that clean water is transported to the second sewage tank 203 through the third pump body 103 for cleaning.

[0090] In this embodiment, the first pump body 206 is an air pump, and the second pump body 208 and the third pump body 103 are water pumps.

[0091] In this embodiment, the first clean water tank 101 of the base station 100 is connected to a faucet to realize automatic water filling, and the first sewage tank 102 of the base station 100 is assembled with a sewage pipe at one end to realize automatic sewage outflow.

[0092] Working principle: When the second clean water tank 207 is empty or the second sewage tank 205 is full of sewage after the floor scrubber 200 has finished mopping the floor, the floor scrubber 200 is placed on the base station 100 .

[0093] Principle of automatic sewage emptying: When the second sewage tank 205 is full of sewage, the two-way valve 204 opens, and at the same time, the normally closed end of the second control valve 202 (three-way valve) changes to normally open to allow atmospheric pressure to flow. The sewage in the second sewage tank 203 automatically flows into the trash bin 205, and then flows into the first sewage tank 102 of the base station 100 through the valve of the trash bin 205. At this time, the automatic emptying of sewage from the second sewage tank 205 of the fuselage is completed;

[0094] Automatic cleaning principle: The third pump body 103 (water pump) of the base station 100 starts working to move the clean water in the first clean water tank 101 through the normally open end of the first control valve 201 (three-way valve) and the normally open end of the second control valve 202 (three-way valve) into the second sewage tank 205 of the fuselage for cleaning, thereby cleaning the second sewage tank 205. After completion, the water pump of the base station 100 stops working, the normally closed end of the second control valve 202 is converted to normally open, and at the same time the two-way valve 204 is opened to enter the atmospheric pressure, and the second sewage tank 205 of the fuselage is cleaned. 3 enters the trash can 205 and flows into the first sewage tank 102 of the base station. At this time, the automatic cleaning of the second sewage tank 203 of the fuselage is completed. After the automatic cleaning of the second sewage tank 203 of the fuselage, the water pump of the base station 100 works again through the first control valve 201, which is normally open. At the same time, the normally open end of the second control valve 201 is closed, and the first pump body 206 (air pump) is started. The water automatically cleans the trash can 205 through the air pump, and the sewage flows from the trash can 205 into the first sewage tank 102 of the base station. At this time, the automatic cleaning of the trash can is completed.

[0095] Principle of automatic water addition: The water pump of the base station 100 is working, at this time the first control valve 201 is normally closed and changes to normally open, and clean water is injected into the second clean water tank 207 of the fuselage. After sensing that the water is full, the water pump stops working, and the second clean water tank 207 is automatically filled with water.

[0096] Working principle of the floor scrubber: After automatic emptying of sewage, automatic cleaning, and water addition, when the floor scrubber 200 needs to be used to mop the floor, the second pump body 208 (water pump) of the floor scrubber 200 sprays the clean water in the second clean water tank 207 of the machine body onto the roller brush 209, and the roller brush 209 rotates to clean the bottom surface. The sewage on the roller brush 209 flows back to the garbage bin 205. At the same time, the first pump body 206 (air pump) and the two-way valve 204 are started to pump the sewage in the garbage bin 205 into the second sewage tank 203 by means of negative pressure.

[0097] Based on the above embodiments, the present invention further provides a control method for a novel water circulation system for a floor scrubber, which is applied to any of the above novel water circulation systems for a floor scrubber, wherein the method comprises:

[0098] Step S100: Receive a storage signal of the liquid to be cleaned in the garbage bin. In this embodiment, the liquid to be cleaned is sewage, but is not limited thereto.

[0099] Step S200: According to the storage signal of the liquid to be cleaned, the second control valve is controlled to extract the liquid to be cleaned from the garbage tank, so that the liquid to be cleaned is extracted into the second sewage tank, completing the storage of the liquid to be cleaned.

[0100] In some implementations, step S200 specifically includes the following steps:

[0101] Step S210: the garbage bin is connected to the second sewage tank;

[0102] Step S220: Control the first pump body to vacuum extract the liquid to be cleaned in the garbage bin, so that the liquid to be cleaned in the garbage bin is sucked into the second sewage tank;

[0103] Specifically, the two-way valve 204 is opened to connect the second sewage tank 203 with the garbage bin 205. At this time, the inlet end of the second control valve 202 that is connected to the outside is in a closed state, so that the garbage bin 205 and the second sewage tank 203 are in a sealed state; by starting the air pump 206 to vacuum, the second sewage tank 203 is in a negative pressure state, thereby pumping the sewage in the garbage bin 205 into the second sewage tank 203. After completion, the two-way valve 204 is closed to complete the storage of the sewage (that is, the sewage is temporarily stored in the floor scrubber).

[0104] Step S300: Connect the base station to the floor scrubber to receive a discharge signal of the liquid to be cleaned in the second sewage tank.

[0105] Step S400: According to the discharge signal of the liquid to be cleaned, the second control valve is controlled to discharge the liquid to be cleaned in the second sewage tank into the trash box, and the trash box is controlled to discharge the discharged liquid to be cleaned into the first sewage tank of the base station, thereby completing the discharge of the liquid to be cleaned.

[0106] The step S400 specifically includes the following steps:

[0107] Step S410: The first sewage tank, the garbage tank, and the second sewage tank are connected, and the second sewage tank is connected to the outside world;

[0108] Step S420: The liquid to be cleaned in the second sewage tank is output to the trash tank, and the liquid to be cleaned in the trash tank is discharged to the first sewage tank.

[0109] Specifically, the two-way valve 204 and the inlet end of the second control valve 202 connected to the outside are opened, so that the second sewage tank 203 enters the atmospheric pressure, and then the sewage in the second sewage tank 203 automatically flows into the trash box 205 through the two-way valve 204, and then flows into the first sewage tank 102 of the base station 100 through the valve of the trash box 205, and the sewage discharge of the second sewage tank 205 of the fuselage is completed.

[0110] In some implementations, the method further includes:

[0111] Step S510: Receive a cleaning signal from the second sewage tank and / or the garbage tank.

[0112] Step S520: Control the third pump body to perform sealed spray cleaning on the second sewage tank and / or the garbage bin according to the cleaning signal of the second sewage tank and / or the garbage bin.

[0113] Specifically, the two-way valve is closed, and the inlet end of the second control valve connected to the outside is closed, and the water pump of the base station is started, so that the cleaning liquid (i.e., clean water) in the first clean water tank 101 passes through the first control valve 201 and the second control valve 202 in sequence, and is sprayed out from the second sewage tank 203 for cleaning; the two-way valve 204 is closed, and the water inlet end of the second control valve 202 is closed at the same time, thereby starting the water pump of the base station and the air pump 206 of the floor scrubber, so that the clean water in the first clean water tank 101 passes through the first control valve 201 and the air pump 206 in sequence, and is sprayed out from the garbage tank 205 for cleaning.

[0114] Step S530: The spraying liquid in the second sewage tank and / or the garbage tank is discharged into the first sewage tank, thereby completing the cleaning of the second sewage tank and / or the garbage tank.

[0115] The present invention achieves the purpose of sewage storage (temporary storage) and sewage discharge by controlling a pipeline through an air pump by connecting the second sewage tank 203, the two-way valve 204 and the garbage bin 205, thereby improving the working efficiency of the base station and the floor scrubber.
