[0034] The specific implementations of the embodiments of the application will be further described with reference to the accompanying drawings.

[0035] At present, when the automatic driving scrubber is using cleaning agent, one way is to manually add the cleaning agent into the water tank, and the automatic driving scrubber uses the water mixed with the cleaning agent to perform cleaning operation; another way is to manually spray the cleaning agent on the ground, and the automatic driving scrubber mixes the water and the cleaning agent when cleaning the ground to perform ground cleaning operation. However, the above-mentioned ways all need manual operation, which is time-consuming and laborious, and the operation cost is high.

[0036] In order to solve the above problems, the embodiment provides an automatic filling device.

[0037] Figure 1 The structure schematic diagram of the automatic filling device 100 of one embodiment of the application is shown, but Figure 1 The specific installation and connection mode of each component is not limited to this. For example Figure 1 As shown, the automatic filling device 100 comprises a liquid inlet pipe 102, a liquid outlet pipe 104, a liquid suction container 106 and a liquid suction pipe 108.

[0038] The first end 1061 of the liquid suction container 106 is connected with the liquid inlet pipe 102, the second end 1062 opposite to the first end 1061 of the liquid suction container 106 is connected with the liquid outlet pipe 104, and the connecting port 1063 sealedly connected with the liquid suction pipe 108 is arranged in the container cavity of the liquid suction container 106; the water injected from the liquid inlet pipe 102 into the liquid suction container 106 and the cleaning agent injected from the liquid suction pipe 108 into the liquid suction container 106 are mixed in the container cavity of the liquid suction container 106 to form cleaning liquid, and then the cleaning liquid is injected into the target container through the liquid outlet pipe 104.

[0039] The liquid suction container 106 can be a cylindrical container or other arbitrary appropriate form container, and its size can be set according to specific application, which is not limited in the embodiment of the application. The liquid suction container 106 is selected from any appropriate material capable of storing cleaning agent, such as stainless steel material, polypropylene material, etc. The first end 1061 and the second end 1062 of the liquid suction container 106 are relative, preferably, the first end 1061 and the second end 1062 of the liquid suction container 106 are respectively two ends of the liquid suction container 106 in the central axis direction. For example, as shown in the figure, if the first end 1061 corresponds to the left side of the liquid suction container 106 in the central axis direction, then the second end 1062 corresponds to the right side. Figure 1 The connecting port 1063 sealedly connected with the liquid suction pipe 108 is arranged in the container cavity of the liquid suction container 106, which can be arranged at any appropriate position in the container cavity of the liquid suction container 106, for example, can be arranged on the upper side or the lower side of the container cavity of the liquid suction container 106, etc. Preferably, it can be arranged on the lower side of the container cavity, so as to more conveniently suck the cleaning agent into the container cavity.

[0040] One end of the liquid inlet pipe 102 is connected with a water supply end such as a faucet, and the other end is connected with a first end of the liquid suction container 106. The connection can be flange connection, sleeve connection, clamping connection, or any other appropriate form. When the faucet is opened, water flows into the liquid suction container 106 from the liquid inlet pipe 102.

[0041] One end of the liquid outlet pipe 104 is connected with a second end of the liquid suction container 106 opposite to the first end. The connection can be the same as or different from the connection of the liquid inlet pipe 102. The other end of the liquid outlet pipe 104 can be placed in a target container, so that the liquid in the liquid suction container 106 can be injected into the target container from the liquid outlet pipe 104. The target container can be a water tank of a scrubber, or any other appropriate container, which is not limited in the embodiments of the present application.

[0042] One end of the liquid suction pipe 108 is sealingly connected with a connecting port provided in the container cavity of the liquid suction container 106, and the other end can be connected with a cleaning agent container. A cleaning agent switch valve can be further provided at the connection between the cleaning agent container and the liquid suction pipe 108. When the cleaning agent switch valve and the faucet are both opened, the cleaning agent in the cleaning agent container is injected into the liquid suction container 106 from the liquid suction pipe 108, the water flows into the liquid suction container 106 from the liquid inlet pipe 102, and then flows out from the liquid outlet pipe 102. The cleaning agent and the water in the liquid suction container 106 are mixed into cleaning liquid, and then are injected into the target container from the liquid outlet pipe 104.

[0043] In a possible implementation, the water injected into the liquid suction container 106 from the liquid inlet pipe 102 forms a negative pressure in the liquid suction container 106, so that the liquid suction container 106 sucks the cleaning agent through the liquid suction pipe 108.

[0044] When the water is injected into the liquid suction container 106 from the liquid inlet pipe 102, the air in the liquid suction container 106 is discharged, resulting in a decrease in the pressure in the liquid suction container 106 and forming a negative pressure. The negative pressure refers to that the pressure in the liquid suction container 106 is lower than the external atmospheric pressure.

[0045] It should be noted that in this case, one end of the liquid suction pipe 108 is sealingly connected with the connecting port provided in the container cavity of the liquid suction container 106, and the other end can be directly placed below the liquid level of the cleaning agent in the cleaning agent container. The cleaning agent in the cleaning agent container can be automatically sucked into the liquid suction container 106. In the embodiments of the present application, the negative pressure is formed in the liquid suction container 106, and due to the siphon principle, the cleaning agent is sucked into the liquid suction container 106 through the liquid suction pipe 108, without the need for power supply, and the automatic injection of the cleaning agent can be realized.

[0046] The inlet pipe 102 and the outlet pipe 104 can be made of any suitable material, such as PPR pipe (random copolymer polypropylene), stainless steel pipe, ABS plastic pipe, etc. Preferably, the inlet pipe 102 and / or the outlet pipe 104 is a stainless steel corrugated pipe. The stainless steel corrugated pipe has high corrosion resistance and high flexibility, thereby ensuring the service life of the inlet pipe 102 and / or the outlet pipe 104 and the flexibility of installation. The materials of the inlet pipe 102, the outlet pipe 104, and the suction pipe 108 can be the same or different, which is not limited in the embodiment of the present application.

[0047] It should be noted that the automatic filling device 100 of the embodiment of the present application can be installed on a scrubber workstation or a cleaning device such as a scrubber. Those skilled in the art can apply the automatic filling device 100 to a suitable scene as needed, which is not limited in the embodiment of the present application.

[0048] In the embodiment of the present application, an automatic filling device 100 is provided, the first end 1061 of the suction container 106 is connected with the inlet pipe 102, the second end 1062 opposite to the first end 1061 of the suction container 106 is connected with the outlet pipe 104, and the container cavity of the suction container 106 is provided with a connecting port 1063 in sealing connection with the suction pipe 108. The water injected from the inlet pipe 102 into the suction container 106 and the cleaning agent injected from the suction pipe 108 into the suction container 106 are mixed in the container cavity of the suction container 106 to form a cleaning liquid, which is injected into a target container through the outlet pipe 104. When the automatic driving cleaning device needs to perform a cleaning operation, the water faucet can be opened, the water flows from the inlet pipe 102 into the suction container 106, the cleaning agent is injected from the suction pipe 108 into the suction container 106, and the cleaning liquid mixed with the cleaning agent in the suction container 106 is injected into the target container through the outlet pipe 104, thereby realizing automatic filling of the cleaning agent. The automatic driving cleaning device uses the water mixed with the cleaning agent, which not only makes the ground cleaning more clean, but also does not need manual operation, thereby solving the problem of time-consuming and laborious manual operation.

[0049] In a possible implementation, a one-way valve is arranged near the connecting port of the suction pipe; when the suction container sucks the cleaning agent, the one-way valve is opened to allow the cleaning agent to flow into the suction container.

[0050] The one-way valve is a valve that controls the one-way flow of fluid. It only allows fluid to flow in one direction and prevents it from flowing in the other direction.

[0051] Figure 2 A structure schematic diagram of an automatic filling device provided with a one-way valve is shown as Figure 2As shown, the one-way valve 110 is arranged at the position close to the connecting port of the liquid suction pipe 108, and can control the flow direction of the liquid. When the liquid suction container 106 sucks the cleaning agent, the one-way valve 110 is opened to enable the cleaning agent to flow from the liquid suction pipe 108 into the liquid suction container 106, and the liquid in the liquid suction container 106 can be prevented from flowing out of the liquid suction pipe 108.

[0052] The type of the one-way valve in the embodiments of the present application can include any appropriate form such as a spring type one-way valve, a ball type one-way valve, a swing type check valve, etc., and the embodiments of the present application are not limited in this regard.

[0053] In the embodiments of the present application, the one-way valve is arranged at the position close to the connecting port of the liquid suction pipe to control the flow direction of the liquid. When the liquid suction container sucks the cleaning agent, the one-way valve is opened to enable the cleaning agent to flow into the liquid suction container, and the liquid in the liquid suction container can be prevented from flowing out of the liquid suction pipe.

[0054] In a possible implementation, an adjusting valve is arranged on the liquid suction pipe at the position away from the connecting port; and the adjusting position of the adjusting valve is determined according to the cleaning agent ratio, the flow rate of the liquid inlet end per unit time and the pipe diameter of the liquid suction pipe, to adjust the flow rate of the cleaning agent injected into the liquid suction container when the cleaning agent ratio of the cleaning agent and water in the container cavity does not reach the cleaning agent ratio.

[0055] If the cleaning agent and water ratio is too large, it may cause excessive foam in the water tank, ground, etc., and if the cleaning agent and water ratio is too small, it may affect the cleaning effect. Therefore, the adjusting valve is arranged on the liquid suction pipe at the position away from the connecting port, the adjusting valve can change the flow rate of the fluid, and the adjusting position of the adjusting valve is controlled to control the flow rate of the cleaning agent. For example, the automatic driving scrubber needs to inject the cleaning agent into the water tank of the automatic driving scrubber after dilution according to the cleaning agent ratio of 1:30, and the automatic driving scrubber is provided with an automatic injection device for injecting the cleaning liquid into the automatic driving scrubber. If the cleaning liquid mixed in the container cavity of the liquid suction container has a ratio greater than 1:30, it means that the water is relatively less and the cleaning agent is relatively more, and therefore the adjusting position of the adjusting valve can be controlled to make the flow rate of the sucked cleaning agent smaller, so as to make the ratio of the mixed cleaning liquid close to the cleaning agent ratio of 1:30. Similarly, if the cleaning liquid mixed in the container cavity of the liquid suction container has a ratio less than 1:30, it means that the water is relatively more and the cleaning agent is relatively less, and therefore the adjusting position of the adjusting valve can be controlled to make the flow rate of the sucked cleaning agent larger.

[0056] Figure 3The structure diagram of the automatic filling device provided with the adjusting valve is shown. The adjusting valve 112 is arranged on the liquid suction pipe 108 far from the connecting port. The flow of the liquid inlet pipe 102 per unit time can be obtained. According to the required cleaning agent ratio and the flow of the liquid inlet pipe 102 per unit time, the cleaning agent flow required to be sucked from the liquid suction pipe 108 can be determined. The flow rate of the cleaning agent in the liquid suction pipe 108 is determined in combination with the pipe diameter of the liquid suction pipe 108. Then, the adjusting position of the adjusting valve 112 is determined according to the flow rate of the cleaning agent. In order to facilitate the observation of the flow rate of the cleaning agent in the liquid suction pipe 108, a vane flowmeter (not shown in the figure) can also be installed on the liquid suction pipe 108. The rotation speed of the vane of the vane flowmeter indicates the flow rate of the cleaning agent in the liquid suction pipe.

[0057] Preferably, in the embodiment of the present application, the adjusting valve can be a ball valve. The ball valve is often used for switching and other switching operations, and has good control performance.

[0058] In the embodiment of the present application, the adjusting valve is arranged on the liquid suction pipe far from the connecting port. The adjusting position of the adjusting valve is determined according to the cleaning agent ratio, the flow of the liquid inlet end per unit time and the pipe diameter of the liquid suction pipe. The flow of the cleaning agent injected into the liquid suction container is adjusted when the ratio of the cleaning agent and water in the container cavity does not reach the cleaning agent ratio, so as to realize the accurate ratio of the cleaning agent and water.

[0059] In a possible implementation, the liquid suction container is arranged in the box body. The liquid suction container is fixed in the box body by the fixing member.

[0060] The box body can be made of metal, plastic, wood or other appropriate materials. The box body can protect the internal structure and provide structural support. The shape of the box body is not limited in the embodiment of the present application.

[0061] The liquid suction container can be arranged in the box body and fixed in the box body by the fixing member. The fixing member can adopt any appropriate form such as a bolt or a fixing clamp.

[0062] Preferably, the fixing member includes at least two fixing clamps. The liquid suction container is clamped and fixed in the box body by the at least two fixing clamps, so that the liquid suction container is not easily shaken and fallen.

[0063] In a possible implementation, the box body is provided with a first outlet and a second outlet. The liquid inlet pipe extends out of the box body through the first outlet, and the liquid outlet pipe extends out of the box body through the second outlet.

[0064] The liquid suction container is arranged in the box, one end of the liquid inlet pipe is connected with the first end of the liquid suction container, and the other end of the liquid inlet pipe needs to be connected with the faucet, and therefore, the first outlet is arranged on the box so that the liquid inlet pipe can extend out of the box through the first outlet. One end of the liquid outlet pipe is connected with the second end of the liquid suction container, and in order to realize that the other end of the liquid outlet pipe injects the mixed cleaning liquid into the target container, the second outlet is arranged on the box so that the liquid outlet pipe can extend out of the box through the second outlet.

[0065] The setting positions and sizes of the first outlet and the second outlet can be set according to the positions and sizes of the liquid inlet pipe and the liquid outlet pipe respectively, and the embodiments of the present application do not limit this.

[0066] In the embodiments of the present application, the first outlet and the second outlet are arranged on the box, so that the liquid inlet pipe and the liquid outlet pipe can extend out of the box through the first outlet and the second outlet to be connected with the faucet and inject the cleaning liquid into the target container.

[0067] In a possible implementation, the first outlet and the second outlet are respectively provided with rubber rings covering the liquid inlet pipe and the liquid outlet pipe.

[0068] The rubber ring is a ring-shaped sealing piece made of rubber material, which can play the roles of sealing, shock absorption, waterproofing and the like. The first outlet and the second outlet are respectively provided with rubber rings covering the liquid inlet pipe and the liquid outlet pipe, which can prevent the edges of the first outlet and the second outlet of the box from scratching the liquid inlet pipe and the liquid outlet pipe, so as to prevent water leakage, and also play the roles of waterproofing and dustproofing.

[0069] Reference Figure 4 , shows an automatic filling device 100 according to another embodiment of the present application, as Figure 4As shown, one end of the liquid inlet pipe 102 is connected with the first end 1061 of the liquid suction container 106, the other end of the liquid inlet pipe 102 is connected with a faucet, one end of the liquid outlet pipe 104 is connected with the second end 1062 of the liquid suction container 106, the other end of the liquid outlet pipe 104 can be placed in a target container, one end of the liquid suction pipe 108 is sealingly connected with the connecting port 1063 arranged in the container cavity of the liquid suction container 106, the other end of the liquid suction pipe 108 can be placed in a cleaning agent container, the liquid suction pipe 108 is provided with a one-way valve 110 near the connecting port 1063, and the liquid suction pipe 108 is provided with an adjusting valve 112 on the side away from the connecting port 1063, the liquid suction container 106 is arranged in a box body 114, the liquid suction container 106 is fixed to the box body by a fixing member 116, the box body 114 is provided with a first outlet 1141 and a second outlet 1142, the liquid inlet pipe 102 extends out of the box body 114 through the first outlet 1141, the liquid outlet pipe 104 extends out of the box body 114 through the second outlet 1142, and the first outlet 1141 and the second outlet 1142 are respectively provided with rubber rings 118 covering the liquid inlet pipe 102 and the liquid outlet pipe 104. When the automatic driving cleaning equipment needs to perform a cleaning operation, the faucet can be opened, and at the same time, the adjusting valve 112 is opened to the maximum, water in the liquid inlet pipe 102 is injected into the liquid suction container 106 to form a negative pressure in the liquid suction container 106, so that the liquid suction container 106 sucks in the cleaning agent through the liquid suction pipe 108, when the liquid suction container 106 sucks in the cleaning agent, the one-way valve 110 is opened, the cleaning agent flows from the liquid suction pipe 108 into the liquid suction container 106, the water and the cleaning agent in the container cavity of the liquid suction container 106 are mixed to form a cleaning liquid, and the cleaning liquid is injected into the target container through the liquid outlet pipe 104.

[0070] If the ratio of the cleaning agent to the water is too large or too small, adverse effects will occur. Therefore, the flow of the cleaning agent injected into the liquid suction container 106 can be adjusted by controlling the adjusting valve 112. First, according to the cleaning agent ratio and the flow of the liquid inlet pipe 102 per unit time, the flow of the cleaning agent sucked in from the liquid suction pipe 108 is determined, then the flow rate of the cleaning agent in the liquid suction pipe 108 is determined according to the pipe diameter of the liquid suction pipe 108, and then the adjusting valve 112 is adjusted to the corresponding adjusting position, so that the ratio of the cleaning agent to the water in the container cavity reaches the cleaning agent ratio, and the cleaning liquid reaching the cleaning agent ratio is injected into the target container for use by the cleaning equipment.
