Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0062] Negative pressure containers are widely used in various industrial fields, such as battery manufacturing, chemical industry, and pharmaceutical industry. Their interiors often need to be cleaned to remove residues, crystals, or contaminants. Negative pressure cleaning tools are used to clean negative pressure containers. Negative pressure cleaning tools use negative pressure technology, combined with cleaning fluids and mechanical devices, to achieve efficient and automated cleaning of negative pressure containers.

[0063] The existing negative pressure cleaning tool cleaning component and chemical integration combination requires the mechanical unit to be locked in a bulky cabinet. This increases the difficulty of installation during the production process and also brings many inconveniences in subsequent maintenance work. Due to the large size and complex structure of the cabinet, maintenance personnel often need to spend more time and energy when performing daily inspections or troubleshooting.

[0064] At the same time, in the prior art, the cleaning process of negative pressure cleaning tools mostly adopts manual cleaning, which is not only inefficient, but also difficult to ensure the thoroughness and consistency of cleaning. Manual cleaning also requires a lot of human resources, thereby increasing the operating costs of enterprises. In addition, since the cleaning process requires manual cleaning, fully automated production and cleaning cannot be achieved, which further limits the cleaning efficiency of negative pressure cleaning tools.

[0065] In order to solve the above problems, the inventors studied the limitations of existing cleaning equipment and designed a cleaning equipment that can automatically clean negative pressure cleaning tooling, thereby avoiding cleaning dead corners caused by manual cleaning and achieving the purpose of improving cleaning efficiency by automatically cleaning negative pressure cleaning tooling.

[0066] Based on this, an embodiment of the present application discloses a cleaning device that can solve the problems caused by traditional manual cleaning of negative pressure cleaning tools.

[0067] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0068] See also Figure 1 , Figure 1 A schematic flow chart of a cleaning method provided in an embodiment of the present application, a second aspect of an embodiment of the present application provides a cleaning method, including: a cleaning method for cleaning equipment, the cleaning equipment including a first liquid storage tank, a cleaning component, and a second liquid storage tank, the first liquid storage tank is connected to the cleaning component, the second liquid storage tank is connected to the cleaning component, the second liquid storage tank is used to connect to a negative pressure cleaning tool, the cleaning method includes:

[0069] Step S1: connecting the negative pressure cleaning tool to the cleaning equipment;

[0070] Step S2: inputting the cleaning solution in the first liquid storage tank into the negative pressure cleaning tool;

[0071] Step S3: pumping the cleaning solution in the negative pressure cleaning tool into the second liquid storage tank;

[0072] Step S4: inputting the cleaning solution in the second liquid storage tank into the negative pressure cleaning tool;

[0073] Step S5: repeat steps S3 and S4 until cleaning is completed;

[0074] Step S6: Repeat step S3 once;

[0075] Step S7: Repeat step S2 once.

[0076] Specifically, the negative pressure cleaning tool is first accurately placed at a predetermined cleaning position, which ensures that the negative pressure cleaning tool can be connected to the cleaning equipment, thereby effectively performing the cleaning operation.

[0077] Subsequently, the cleaning solution in the first liquid storage tank is input into the negative pressure cleaning tool, so that the cleaning solution can smoothly enter the negative pressure cleaning tool and prepare to start the cleaning operation. During the cleaning process, the cleaning solution enters the liquid injection part of the negative pressure cleaning tool through the cleaning joint, and flows into the overflow chamber through the liquid injection part, completing the cleaning of the negative pressure cleaning tool during the entire flow process.

[0078] When the cleaning solution in the negative pressure cleaning tool completes the flow and cleaning process, it is necessary to extract the cleaning solution after cleaning. At this time, the cleaning solution in the negative pressure cleaning tool is pumped into the second liquid storage tank, and the second liquid storage tank can temporarily store the cleaning solution after cleaning.

[0079] After the cleaning solution is pumped into the second liquid storage tank, the cleaning solution in the second liquid storage tank can be input into the negative pressure cleaning tool again for recycling. This step not only improves the utilization rate of the cleaning solution, but also reduces resource waste and environmental pollution.

[0080] It can be understood that the number of cleaning cycles is determined according to the cleaning state of the negative pressure cleaning tool. When the cycle cleaning operation is completed, the remaining cleaning solution in the negative pressure cleaning tool is pumped into the second liquid storage tank. This step ensures the cleanliness and hygiene of the cleaning equipment and is ready for the next cleaning operation.

[0081] Finally, the cleaning solution in the first liquid storage tank is once again input into the negative pressure cleaning tool so that clean cleaning solution is stored in the negative pressure cleaning tool to ensure that the negative pressure cleaning tool can perform the subsequent cleaning process of the negative pressure component.

[0082] In this way, the cleaning method provided in the embodiment of the present application can clean the negative pressure cleaning tooling by the flow of cleaning solution from the first liquid storage tank to the negative pressure cleaning tooling, and then the cleaning solution in the negative pressure cleaning tooling can be pumped into the second liquid storage tank, and the cleaning solution in the second liquid storage tank can be re-input into the negative pressure cleaning tooling for repeated cycle cleaning, so as to reduce the consumption of cleaning solution while ensuring the cleaning effect, and finally the clean cleaning solution in the first liquid storage tank is input into the negative pressure cleaning tooling to realize automatic cleaning of the negative pressure cleaning tooling, thereby improving the accuracy of the cleaning operation of the negative pressure cleaning tooling, avoiding cleaning dead corners caused by manual operation, and improving the efficiency of cleaning the negative pressure cleaning tooling.

[0083] See also Figure 2 , Figure 2 A flow chart of step S2 is provided for an embodiment of the present application. In some embodiments, the cleaning equipment also includes a second atmospheric switch valve, a first connecting valve and a first negative pressure valve, and step S2 also includes: step S21: opening the second atmospheric switch valve to connect the first liquid storage tank to the atmosphere; step S22: opening the first connecting valve and the first negative pressure valve to allow the cleaning solution to flow into the negative pressure cleaning tooling.

[0084] First, open the first atmospheric switch valve to connect the first liquid storage tank to the external atmosphere, thereby ensuring that the cleaning solution inside the first liquid storage tank will not be unable to flow into the negative pressure cleaning tooling due to the air pressure difference. At the same time, this step can ensure the stability of the internal environment of the first liquid storage tank and the purity of the cleaning solution. By opening the first atmospheric switch valve, external clean air can enter the first liquid storage tank, which helps prevent the quality of the cleaning solution from being affected by internal gas accumulation or contamination.

[0085] Secondly, open the first connecting valve and the first negative pressure valve at the same time. The opening of the first connecting valve provides a necessary channel for the flow of the cleaning solution from the liquid storage tank to the negative pressure cleaning tool. The opening of the first negative pressure valve allows the negative pressure generated by the negative pressure generating component to be transmitted to the first liquid storage tank, creating a negative pressure environment for the delivery of the cleaning solution. In this way, under the action of negative pressure, the cleaning solution can flow into the negative pressure cleaning tool more efficiently through the liquid supply pipeline, thereby achieving high-quality cleaning operations.

[0086] See also Figure 3 , Figure 3 A flow chart of step S3 is provided for an embodiment of the present application. In some embodiments, the cleaning equipment also includes a second negative pressure valve, a first liquid outlet valve and a first air inlet valve, and step S3 also includes: step S31: opening the first air inlet valve to connect the overflow chamber to the atmosphere; step S32: opening the second negative pressure valve and the first liquid outlet valve; step S33: controlling the negative pressure generating part to form negative pressure so that the cleaning solution flows from the negative pressure cleaning tooling to the second liquid storage tank.

[0087] First, open the first air inlet valve. The opening of the first air inlet valve connects the negative pressure cleaning tool to the atmosphere, thereby ensuring that the cleaning solution inside the negative pressure cleaning tool is not unable to flow into the second liquid storage tank due to the air pressure difference, providing the necessary air pressure conditions for the recovery of the cleaning solution.

[0088] Secondly, the second negative pressure valve and the first liquid outlet valve are opened to connect the negative pressure cleaning tool with the negative pressure generating element, thereby providing necessary negative pressure conditions for the recovery of the cleaning solution.

[0089] Finally, control the negative pressure generating component to form negative pressure. The negative pressure generating component is a key component in the cleaning equipment, which can generate a negative pressure environment by pumping or inhaling air. After opening the second negative pressure valve and the first liquid outlet valve, it is necessary to start the negative pressure generating component and adjust its working state to ensure that sufficient negative pressure is formed inside the negative pressure cleaning tool. In this way, under the action of negative pressure, the cleaning solution can be drawn out from the inside of the negative pressure cleaning tool and flow to the second liquid storage tank along the set fluid channel.

[0090] See also Figure 4 , Figure 4A flow chart of step S4 is provided for an embodiment of the present application. In some embodiments, the cleaning equipment also includes a second atmospheric switch valve, a second connecting valve and a first negative pressure valve, and step S4 also includes: step S41: open the second atmospheric switch valve to connect the second liquid storage tank to the atmosphere; step S42: open the second connecting valve and the first negative pressure valve to allow the cleaning solution to flow from the second liquid storage tank into the negative pressure cleaning tooling.

[0091] First, open the second atmospheric switch valve. The purpose of this step is to ensure that the air pressure inside the second liquid storage tank is stable and allow external air to enter the liquid storage tank to maintain the normal flow of the cleaning solution. At the same time, opening the atmospheric switch valve also helps prevent leakage or poor flow of the cleaning solution caused by changes in the air pressure inside the second liquid storage tank. Next, open the second connecting valve and the first negative pressure valve. The second connecting valve connects the liquid supply line between the second liquid storage tank and the negative pressure cleaning tooling, allowing the cleaning solution to flow along this path.

[0092] In some embodiments, between step S1 and step S2, the cleaning method further includes: inputting the cleaning solution into a first liquid storage tank. The first liquid storage tank serves as a storage and supply source of the cleaning solution, providing necessary cleaning solution support for the subsequent cleaning process.

[0093] Specifically, the cleaning device further includes a liquid supply switch valve and an exhaust valve, and the step of inputting the cleaning solution into the first liquid storage tank further includes: opening the liquid supply switch valve and the exhaust valve to allow the cleaning solution to flow into the first liquid storage tank.

[0094] First, open the liquid supply switch valve. This step is the key to ensure that the cleaning solution can flow smoothly from the liquid supply source into the first liquid storage tank. The opening of the liquid supply switch valve provides a necessary channel for the delivery of the cleaning solution.

[0095] Secondly, open the exhaust valve at the same time. Since gas may be generated during the cleaning process or the original gas in the first liquid storage tank and the second negative pressure pipeline needs to be removed, the opening of the exhaust valve helps to keep the exhaust pipeline unobstructed and stable, and also ensures that the liquid supply pipeline is filled with cleaning solution, thereby ensuring that the cleaning solution can flow smoothly and avoid the occurrence of bubbles or interruption. In this way, as the cleaning solution enters, the gas in the first liquid storage tank can be discharged smoothly to avoid the formation of gas blockage or affect the cleaning effect.

[0096] In some embodiments, after step S7, the cleaning method also includes: opening the second atmospheric switch valve and the first liquid outlet valve to allow the cleaning solution between the negative pressure cleaning tooling and the second liquid storage tank to flow into the negative pressure cleaning tooling; opening the second negative pressure valve to discharge the cleaning solution in the second negative pressure pipeline.

[0097] Open the second atmospheric switch valve to allow external air to enter the second connecting pipeline to help balance the air pressure in the second connecting pipeline, so that the cleaning solution in the second connecting pipeline flows into the negative pressure cleaning tool. The purpose of this step is to ensure that there is no residual cleaning solution in the second connecting pipeline to prevent it from drying, crystallizing or causing blockage.

[0098] Open the second negative pressure valve to allow external air to enter the second negative pressure pipeline to help balance the air pressure in the second negative pressure pipeline, so that the cleaning solution in the second negative pressure pipeline flows into the negative pressure cleaning tool. The purpose of this step is to ensure that there is no residual cleaning solution in the second negative pressure pipeline to prevent it from drying up, crystallizing or causing blockage.

[0099] In some embodiments, the cleaning equipment also includes a diversion component, which is connected to the first liquid storage tank, the second liquid storage tank and multiple cleaning joints. After step S7, the cleaning method also includes: opening the third atmospheric switch valve to allow the cleaning solution in the diversion component to flow into the negative pressure cleaning tooling.

[0100] Open the third atmosphere switch valve to allow external air to enter the third atmosphere pipeline to help balance the air pressure in the diverter block, so that the cleaning solution in the diverter block flows into the negative pressure cleaning tooling. The purpose of this step is to ensure that there is no residual cleaning solution in the diverter block to prevent it from drying up, crystallizing or causing blockage.

[0101] See also Figure 5 , Figure 5 A flow chart of step S1 is provided for an embodiment of the present application. In some embodiments, the cleaning device also includes: a first bracket; a second bracket, the second bracket is movably connected to the first bracket; the cleaning component includes a cleaning connector, and the cleaning connector can be connected to the injection part of the negative pressure cleaning tooling. Step S1 also includes: step S11: control the second bracket and the first bracket to move away from each other; step S12: set the negative pressure cleaning tooling on the first bracket; step S13: control the second bracket and the first bracket to move closer to each other; step S14: connect the injection part of the negative pressure cleaning tooling to the cleaning connector.

[0102] In the overall process of configuring the negative pressure cleaning tool to the cleaning position, the second bracket must first be controlled to move smoothly along the preset trajectory away from the first bracket until the second bracket reaches the standby position. This step reserves sufficient space for the installation and subsequent connection operations of the negative pressure cleaning tool. Then, the negative pressure cleaning tool is placed on the first bracket to ensure that the injection part of the negative pressure cleaning tool can be aligned with the cleaning connector on the second bracket.

[0103] Next, the second bracket is controlled to approach the first bracket so that the cleaning joint is close to the injection part of the negative pressure cleaning tool. Finally, the injection part of the negative pressure cleaning tool is connected to the cleaning joint to ensure that the cleaning solution in the cleaning joint can be input into the injection part and then enter the negative pressure cleaning tool.

[0104] In some embodiments, the negative pressure cleaning tooling includes a first drain valve and a second drain valve, the first drain valve is connected to the first liquid storage tank, the second drain valve is connected to the second liquid storage tank, the cleaning equipment also includes a second negative pressure valve, and after step S7, the cleaning method also includes: opening the first drain valve to discharge the cleaning medium in the first liquid storage tank; opening the second drain valve to discharge the cleaning medium in the second liquid storage tank.

[0105] After the negative pressure cleaning tool completes the cleaning step S7, it immediately enters the cleaning medium discharge stage. At this time, the first drain valve and the second drain valve need to be opened in sequence to smoothly discharge the cleaning medium in the first liquid storage tank and the second liquid storage tank respectively. This process is to empty the first liquid storage tank and the second liquid storage tank in preparation for subsequent cleaning operations or cleaning medium replacement.

[0106] Furthermore, the discharged cleaning media can be handled appropriately, which may include collection, storage and further recycling or disposal steps to meet relevant environmental regulations.

[0121] The cleaning mechanism 2 also includes a second liquid storage tank 23. The second liquid storage tank 23 is connected to the cleaning assembly 22 and is connected to the overflow chamber 201 of the negative pressure cleaning tool 200. During the cleaning process, when the internal pressure of the negative pressure cleaning tool 200 reaches a certain level, the excess cleaning solution will enter the overflow chamber 201. When the process of the first liquid storage tank 21 inputting the cleaning solution into the negative pressure cleaning tool 200 is completed, the cleaning solution in the negative pressure cleaning tool 200 can be sucked into the second liquid storage tank 23.

Due to the precise matching of the guide rod 122 and the guide sleeve 123, the movement of the carrier 121 will remain on a stable straight line, thereby ensuring the accuracy and stability of the entire driving process.
