[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Figure 1 This diagram shows the structure of a cleaning machine according to an embodiment of the present invention. Figure 2 A schematic diagram showing the connection relationship of various parts of the cleaning machine provided in an embodiment of this utility model is shown. The first valve 403, the second valve 502, and the third valve 503 provided in the embodiments of this application are all used to control the on / off state of the pipeline they are in, and can be solenoid valves, pneumatic valves, diaphragm valves, etc. The specific structure of the first valve 403, the second valve 502, and the third valve 503 is not limited here. Any valve that can be controlled by circuit is protected by this application, and will not be described in detail below.

[0044] This utility model provides a negative pressure component cleaning machine for cleaning negative pressure components 300, such as... Figure 2 As shown, the bottom of the negative pressure component 300 is provided with multiple lower interfaces 302, and the negative pressure component 300 extends along its length direction ( Figure 1 and Figure 2The cleaning machine (shown in the X direction) has a water supply interface 303 at one end. It includes a manifold 201, a soaking system 400, and a flushing system 500. The manifold 201 is located below the negative pressure component 300 and is detachably connected to it. Both ends of the manifold 201 along its length have inlets 202 and outlets 203. The top of the manifold 201 has multiple upper interfaces 204, the number of which is equal to the number of lower interfaces 302, and each upper interface 204 is connected to one lower interface 302. The soaking system 400 has its inlet connected to a water source and its outlet connected to the inlet 202 on the manifold 201. The soaking system 400 supplies water to the negative pressure component 300 through the lower interfaces 302 to soak the inner wall of the negative pressure component 300. The inlet of the flushing system 500 is connected to a water source, and the outlet of the flushing system 500 is connected to a water supply interface 303. The flushing system 500 is used to flush out the liquid and impurities in the negative pressure component 300 from the drain outlet 203 and out of the negative pressure component 300 and the manifold 201.

[0045] By adopting the above technical solution, the cleaning machine provided by this utility model constructs a manifold 201 with multiple upper interfaces 204 and connects each upper interface 204 to each lower interface 302 of the negative pressure component 300. The immersion system 400 inputs cleaning water into the manifold 201, which allows the inner wall of the negative pressure component 300 adjacent to each lower interface 302 to be immersed in water, softening or even partially dissolving the crystals on the inner wall of the negative pressure component 300. The flushing system 500 inputs cleaning water into the water supply interface 303 of the negative pressure component 300, which facilitates the flushing off of the softened crystals on the inner wall of the negative pressure component 300. The impurities generated by flushing the inner wall are flushed from the lower interface 302 into the manifold 201 and discharged through the drain outlet 203 of the manifold 201. Compared to existing technologies that only use high-pressure hot water to flush the negative pressure component 300, this invention cleans the inner wall of the negative pressure component 300 by combining soaking and flushing processes, which can improve the cleaning efficiency of the negative pressure component 300.

[0046] Furthermore, such as Figure 2As shown, the soaking system 400 includes a main pipeline 401, a drive pump 402, a first valve 403, and a first filter 404. The inlet of the main pipeline 401 is connected to a water source, and the outlet of the main pipeline 401 is connected to the inlet 202 of the manifold 201. The drive pump 402 is mounted on the main pipeline 401 and is used to drive the cleaning water supplied by the water source to flow towards the manifold 201. Specifically, the drive pump 402 can be a diaphragm pump or other types of pumps; the structure of the drive pump is not limited here. Any pump capable of driving the cleaning water to flow towards the manifold 201 is within the scope of protection of this application. The first valve 403 is mounted on the main pipeline 401 and located between the drive pump 402 and the manifold 201. The first valve 403 is used to control the opening and closing of the main pipeline 401. Specifically, the volume of cleaning water required to soak the negative pressure component 300 is fixed. At the start of the soaking process, the first valve 403 opens, supplying cleaning water into the manifold 201 and the negative pressure component 300. When both the negative pressure component 300 and the manifold 201 are full of water, the first valve 403 and the drive pump 402 close, stopping the supply of cleaning water to the negative pressure component 300 and the manifold 201, while preventing backflow of cleaning water from the negative pressure component 300. The method for controlling the volume of cleaning water supplied to the negative pressure component 300 and the manifold 201 is not limited here; it can be achieved by controlling the opening time of the drive pump 402 and the first valve 403, or by detecting the internal page height of the negative pressure component 300. Additionally, to prevent excessive internal air pressure in the negative pressure component 300 from affecting the entry of cleaning water, an exhaust vent can be provided at the top of the negative pressure component 300. The vent can be opened when the first valve 403 is opened and closed when the flushing system 500 starts working to prevent the cleaning water input to the flushing system 500 from leaking out of the vent.

[0047] The first filter 404 is installed on the main pipeline 401 and located between the drive pump 402 and the water source. The first filter 404 is used to filter impurities in the cleaning water. On the one hand, it prevents impurities in the cleaning water from entering the drive pump 402 and the negative pressure assembly 300 and causing corrosion or wear to the internal structure of the drive pump 402 and the negative pressure assembly 300. On the other hand, it prevents impurities in the cleaning water from accumulating on the inner wall of the main pipeline 401 and affecting the conveying efficiency of the main pipeline 401.

[0048] Furthermore, such as Figure 2As shown, the flushing system 500 includes a branch pipe 501, a liquid storage tank 503, a compressed air source 504, a second valve 502, and a third valve 505. The input end of the branch pipe 501 is connected to the main pipe 401, and the connection point between the input end of the branch pipe 501 and the main pipe 401 is located between the drive pump 402 and the first valve 403, allowing the branch pipe 501 and the main pipe 401 to share the drive pump 402, thus improving the efficiency of the drive pump 402. The output end of the branch pipe 501 is connected to the water supply interface 303 on the negative pressure assembly 300 to provide cleaning water to the negative pressure assembly 300, flushing the inner wall of the negative pressure assembly 300.

[0049] A storage tank 503 is located on branch pipe 501 and is used to store cleaning water for flushing the negative pressure component 300. A compressed air source 504 is connected to the storage tank 503 and is used to supply compressed gas into the storage tank 503 to increase the speed of the water flow output from the storage tank 503. A second valve 502 is located on branch pipe 501 and between the storage tank 503 and the drive pump 402. The second valve 502 is used to control the supply of cleaning water from branch pipe 501 to the storage tank 503. A third valve 505 is located on branch pipe 501 and between the storage tank 503 and the negative pressure component 300. The third valve 505 is used to control the spraying of water from the storage tank 503 into the water supply interface 303 of the negative pressure component 300. After the soaking process completes and the inner wall of the negative pressure component 300 is soaked, the rinsing process begins. In the rinsing process, the rinsing system 500 begins rinsing the inner wall of the negative pressure component 300. Specifically, after entering the rinsing system 500, the drive pump 402 starts to deliver cleaning water, the second valve 502 opens and the third valve 505 closes, allowing the cleaning water to enter the storage tank 503 for storage. Once the storage tank 503 is full of cleaning water, the diaphragm valve and the second valve 502 are closed to stop the flow of water into the storage tank 503 and prevent backflow of the cleaning water. The third valve 505 is then opened to connect the storage tank 503 to the negative pressure component 300. Subsequently, the compressed air source 504 introduces compressed gas into the storage tank 503 to spray the cleaning water from the storage tank 503 into the negative pressure component 300 at a high speed, rinsing the inner wall of the negative pressure component 300. It is worth mentioning that the compressed air source 504 can be a high-pressure air pump, which, after being powered on, can input compressed gas into the liquid storage tank 503; or it can be a high-pressure air tank, which contains high-pressure gas, and when the valve of the high-pressure air tank is opened, it can deliver compressed gas into the liquid storage tank 503. In addition, the valve of the high-pressure air tank can be an electrically controlled valve or a needle valve, ball valve, etc., that can be opened by an electric mechanism, which facilitates the automated control of the cleaning machine.

[0050] Furthermore, such as Figure 2As shown, a sealing mechanism 210 is provided on the outside of the drain outlet 203 of the manifold 201. The sealing mechanism 210 is used to close the drain outlet 203 when the soaking system 400 is working, and to open the drain outlet 203 when the flushing system 500 is working. Specifically, the sealing mechanism 210 includes a sealing cylinder 211 and a sealing plug 212. The driving end of the sealing cylinder 211 faces the drain outlet 203, and the sealing plug 212 is located at the driving end of the sealing cylinder 211. The sealing cylinder 211 is used to cover the sealing plug 212 on the drain outlet 203 and apply pressure to the sealing plug 212 to seal the drain outlet 203.

[0051] Furthermore, the cleaning machine also includes a control system, which is electrically connected to the drive pump 402, the first valve 403, the second valve 502, the third valve 505, the sealing mechanism 210, and the compressed air source 504. When the soaking system 400 is operating, the control system controls the sealing mechanism 210 to close the drain outlet 203, controls the first valve 403 to open for a fixed duration and then close, and controls the sealing mechanism 210 to open the drain outlet 203 after a first preset time. During the opening and closing of the first valve 403, a fixed amount of water is supplied to the manifold 201 and the negative pressure assembly 300. During the delay, a fixed amount of water is maintained in the negative pressure assembly 300 to soak its inner wall, softening and loosening any crystals on the inner wall.

[0052] When the flushing system 500 is operating, the control system controls the opening of the second valve 502 and the closing of the third valve 505 to fill the storage tank 503 with water; and delays for a fixed period of time to control the closing of the second valve 502, the opening of the third valve 505, and the activation of the compressed air source 504 to flush the inside of the negative pressure component 300. The fixed period of time is the time required to fill the storage tank 503 with water, which is the ratio of the volume of the storage tank 503 to the output flow rate of the drive pump 402.

[0053] Furthermore, such as Figure 1 and Figure 2 As shown, the water source is a water tank 100. The water tank 100 has an inlet pipe 101 at its inlet end and a heating rod 102 inside. The inlet pipe 101 is connected to a tap water source, and the heating rod 102 is used to heat the cleaning water in the water tank 100. A third filter 103 is installed on the inlet pipe 101 to purify the tap water for cleaning. This filter removes impurities such as sediment and rust from the tap water, preventing damage to the water tank 100, the heating rod 102, and the drive pump 402.

[0054] Furthermore, such as Figure 2As shown, the cleaning machine also includes a liquid recovery system 700, which includes a water collection tank 704, a return pipe 701, a return pump 702, and a second filter 703. The water collection tank 704 is located below the drain outlet 203 and is used to collect the liquid output from the drain outlet 203. The inlet end of the return pipe 701 is connected to the water collection tank 704, and the outlet end of the return pipe 701 is connected to the water tank 100. The return pump 702 is located on the return pipe 701 and is used to drive the liquid in the water collection tank 704 back to the water tank 100. The second filter 703 is located on the return pipe 701 and between the water collection tank 704 and the return pump 702. The second filter 703 is used to filter impurities in the liquid output from the water collection tank 704. The liquid recovery system 700 recovers the liquid generated by the cleaning negative pressure component 300, thus conserving water resources. The second filter 703 separates impurities (mainly electrolyte crystals) from the liquid and can also recycle the crystals, such as precious metals and catalysts. The recovered crystals can also be used for scientific research. By analyzing the properties of the crystals and feeding them back into electrolyte production, researchers can study how to improve the electrolyte to reduce the formation of crystals.

[0055] Furthermore, such as Figure 1 As shown, the cleaning machine also includes a frame 800, which has a first compartment 801, a second compartment 802 and a third compartment 803. The first compartment 801 is located above the second compartment 802 and the third compartment 803. The manifold 201, the negative pressure component 300 and the liquid storage tank 503 are located in the first compartment 801. The second compartment 802 and the third compartment 803 are adjacent to each other. The water tank 100 and the drive pump 402 are located in the second compartment 802. The first valve 403 and the second valve 502 are located in the third compartment 803.

[0056] Furthermore, such as Figure 2 As shown, the negative pressure assembly 300 includes a plurality of negative pressure cups 301. The number of upper interfaces 204 is equal to the number of negative pressure cups 301. Each negative pressure cup 301 is connected along the length of the negative pressure assembly 300, and each negative pressure cup 301 has a lower interface 302 at its lower end.
