[0043] Negative pressure vessels are widely used in various industrial sectors, such as battery manufacturing, chemical, and pharmaceutical industries. Their interiors frequently require cleaning to remove residues, crystals, or contaminants. Negative pressure cleaning fixtures are used to clean these vessels. By utilizing negative pressure technology, combined with cleaning fluids and mechanical devices, these fixtures achieve efficient and automated cleaning of negative pressure vessels.

[0044] Existing negative pressure cleaning fixtures integrate cleaning components with chemical conversion processes, requiring the mechanical units to be locked within a bulky cabinet. This increases installation difficulty during production and creates numerous inconveniences for subsequent maintenance. Due to the large size and complex structure of the cabinet, maintenance personnel often need to devote more time and effort to routine inspections and troubleshooting.

[0045] Meanwhile, existing technologies for cleaning negative pressure cleaning equipment mostly rely on manual cleaning, which is not only inefficient but also makes it difficult to guarantee thoroughness and consistency. Manual cleaning also requires a significant investment of human resources, increasing operating costs for businesses. Furthermore, the need for manual cleaning prevents fully automated production and cleaning, further limiting the cleaning efficiency of negative pressure cleaning equipment.

[0046] To address the aforementioned issues, the inventors investigated the limitations of existing cleaning equipment and designed a cleaning device capable of automating the cleaning of negative pressure cleaning fixtures. This prevented cleaning blind spots caused by manual cleaning and achieved the goal of improving cleaning efficiency through automated cleaning of negative pressure cleaning fixtures.

[0047] Based on this, the present application discloses a cleaning device that can solve the problems caused by traditional manual operation of negative pressure cleaning equipment.

[0048] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0049] Please see Figures 1 to 5 , Figure 1 This is one of the structural schematic diagrams of the cleaning device 100 provided in the embodiments of this application; Figure 2 This is a second schematic diagram of the structure of the cleaning device 100 provided in the embodiments of this application; Figure 3 This is the third schematic diagram of the structure of the cleaning device 100 provided in the embodiments of this application; Figure 4 This is the fourth schematic diagram of the structure of the cleaning device 100 provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the negative pressure cleaning fixture 200 provided in this application embodiment. This application embodiment discloses a cleaning device 100 for cleaning the negative pressure cleaning fixture 200. The negative pressure cleaning fixture 200 includes an overflow chamber 201 and a liquid injection component 202 communicating with the overflow chamber 201. The cleaning device 100 includes: a support assembly 1, which includes a first support 11 and a second support 12, the first support 11 and the second support 12 being movably connected in the vertical direction, the first support 11 being used to support the negative pressure cleaning fixture 200; and a cleaning mechanism 2, which is disposed on the second support 12. The structure 2 includes a first liquid storage tank 21 and a cleaning component 22 that are interconnected. The first liquid storage tank 21 can provide cleaning solution to the cleaning component 22. The cleaning component 22 includes multiple cleaning connectors 221 that can be connected to the injection component 202 of the negative pressure cleaning fixture 200. A diversion component 3 is disposed on the second support 12 and is connected to the first liquid storage tank 21 and the multiple cleaning connectors 221. The diversion component 3 is used to disperse the cleaning solution in the first liquid storage tank 21 into the multiple cleaning connectors 221.

[0050] The supporting component 1 includes a first bracket 11 and a second bracket 12. The first bracket 11 is a supporting structure for the negative pressure cleaning fixture 200, which is used to support the negative pressure cleaning fixture 200 and other structures of the cleaning equipment 100 to ensure that the negative pressure cleaning fixture 200 will not shake or fall off due to external force or internal pressure during the entire cleaning process, thereby ensuring the cleaning effect of the negative pressure cleaning fixture 200.

[0051] The second bracket 12 is movably connected to the first bracket 11 in the vertical direction. It can be understood that the second bracket 12 can move in the vertical direction, providing a flexible connection between the cleaning component 22 and the liquid injection part 202 of the negative pressure cleaning fixture 200. This ensures that when the negative pressure cleaning fixture 200 is installed on the first bracket 11, the cleaning component 22 can avoid the negative pressure cleaning fixture 200, thus preventing interference between the cleaning component 22 and the negative pressure cleaning fixture 200.

[0052] Furthermore, the supporting assembly 1 may include a drive member 13, which is connected to the first bracket 11 and the second bracket 12. The function of the drive member 13 is to provide power to drive the second bracket 12 and / or the first bracket 11 to move in the vertical direction. In this way, the second bracket 12 and the first bracket 11 can move closer to or further away from each other as needed to avoid the negative pressure cleaning fixture 200.

[0053] The cleaning mechanism 2 includes a first liquid storage tank 21 and a cleaning component 22. The first liquid storage tank 21 and the cleaning component 22 work together to ensure that the cleaning solution can be accurately delivered to the injection part 202 of the negative pressure cleaning fixture 200, thereby achieving the cleaning purpose.

[0054] Furthermore, the first storage tank 21 is the main storage container for the cleaning solution, and the first storage tank 21 is connected to the cleaning assembly 22. The cleaning assembly 22 is responsible for delivering the cleaning solution to the injection component 202 of the negative pressure cleaning fixture 200. The cleaning assembly 22 is mounted on the second support 12 and located on the side of the second support 12 closer to the first support 11, so as to ensure that the cleaning assembly 22 is close to the negative pressure cleaning fixture 200 and can move with the second support 12.

[0055] When the cleaning assembly 22 moves away from the negative pressure cleaning fixture 200 along with the second bracket 12, the cleaning connector 221 can move along with the second bracket 12 to avoid the negative pressure cleaning fixture 200, thereby ensuring that there is no interference between the cleaning assembly 22 and the negative pressure cleaning fixture 200.

[0056] When the cleaning assembly 22 moves with the second bracket 12 toward a position close to the negative pressure cleaning fixture 200, the cleaning connector 221 can be connected to the liquid injection component 202 of the negative pressure cleaning fixture 200, and the cleaning solution can be transported from the first storage tank 21 to the liquid injection component 202 of the negative pressure cleaning fixture 200 through the cleaning assembly 22, thereby starting the cleaning process.

[0057] Alternatively, the connection between the cleaning connector 221 and the liquid injection part 202 of the negative pressure cleaning fixture 200 can be achieved through other forms of connection mechanisms such as threads, snaps, or hoses.

[0058] The number of cleaning connectors 221 is designed to be multiple. The cleaning connectors 221 are connected to the first liquid storage tank 21, so that the cleaning equipment 100 can input the cleaning solution into multiple liquid injection parts 202 through multiple cleaning connectors 221, which ensures the uniformity and comprehensiveness of the cleaning of the negative pressure cleaning fixture 200 and prevents the liquid injection parts 202 of the negative pressure cleaning fixture 200 from having cleaning dead corners.

[0059] The cleaning equipment 100 also includes a diversion component 3, which can be disposed on the side of the first support 11 away from the cleaning component 22. The diversion component 3 is connected to the first storage tank 21 and multiple cleaning connectors 221. The main function of the diversion component 3 is to accurately distribute the cleaning solution from the first storage tank 21 into the multiple cleaning connectors 221.

[0060] It is understandable that the connection between the diversion component 3 and multiple cleaning connectors 221 can ensure that each cleaning connector 221 can obtain an appropriate amount of cleaning solution, thereby achieving comprehensive, uniform and efficient cleaning of all parts of the negative pressure cleaning fixture 200.

[0061] Thus, the cleaning equipment 100 provided in this application embodiment can drive the cleaning component 22 to move through the supporting component 1, so that the cleaning connector 221 of the cleaning component 22 can be connected to the liquid injection component 202 of the negative pressure cleaning fixture 200, and the cleaning solution in the first storage tank 21 is diverted by the diversion component 3 and input into multiple cleaning connectors 221, and then input into the liquid injection component 202 of the negative pressure cleaning fixture 200 through the cleaning connectors 221, thereby realizing the automated cleaning of the negative pressure cleaning fixture 200, improving the accuracy of the cleaning operation of the negative pressure cleaning fixture 200, avoiding cleaning dead corners caused by manual operation, and improving the efficiency of cleaning the negative pressure cleaning fixture 200.

[0062] Please see Figures 1 to 4 In some embodiments, the cleaning mechanism 2 further includes: a second liquid storage tank 23, which is connected to the cleaning assembly 22. The second liquid storage tank 23 is used to connect to the overflow chamber 201 of the negative pressure cleaning fixture 200. The second liquid storage tank 23 can collect the cleaning solution in the overflow chamber 201 and input the collected cleaning solution into the cleaning assembly 22. The second liquid storage tank 23 is connected to the diversion assembly 3, which is used to distribute the cleaning solution in the second liquid storage tank 23 into multiple cleaning connectors 221.

[0063] The cleaning mechanism 2 also includes a second storage tank 23. The second storage tank 23 is connected to the cleaning assembly 22 and to the overflow chamber 201 of the negative pressure cleaning fixture 200. During the cleaning process, when the internal pressure of the negative pressure cleaning fixture 200 reaches a certain level, excess cleaning solution will enter the overflow chamber 201. After the process of inputting cleaning solution from the first storage tank 21 into the negative pressure cleaning fixture 200 is completed, the cleaning solution in the negative pressure cleaning fixture 200 can be drawn into the second storage tank 23.

[0064] Furthermore, the second storage tank 23 can also re-input the collected cleaning solution into the cleaning assembly 22, realizing the recycling of the cleaning solution, improving the utilization rate of the cleaning solution, reducing resource waste, and helping to maintain the stability and continuity of the cleaning process. By continuously recycling the cleaning solution, the consistency and efficiency of the cleaning effect can be guaranteed.

[0065] Meanwhile, the second liquid storage tank 23 is connected to the diversion component 3, which can disperse the cleaning solution from the second liquid storage tank 23 into multiple cleaning connectors 221. The connection between the diversion component 3 and the multiple cleaning connectors 221 ensures that each cleaning connector 221 receives an appropriate amount of cleaning solution, thereby achieving comprehensive, uniform, and efficient cleaning of all parts of the negative pressure cleaning fixture 200.

[0066] Please see Figure 6 , Figure 6 The diagram below illustrates the structure of the cleaning assembly 22 and the diversion assembly 3 provided in the embodiments of this application. In some embodiments, the diversion assembly 3 includes: a primary diversion component 31, which has a first confluence chamber inside. The primary diversion component 31 includes a first inlet, a second inlet, and a plurality of first outlets. The first inlet, the second inlet, and the plurality of first outlets are connected to the first confluence chamber. The first inlet is connected to the first storage tank 21, and the second inlet is connected to the second storage tank 23. Also included are a plurality of secondary diversion components 32, which have a second confluence chamber inside. The plurality of secondary diversion components 32 include a plurality of third inlets and a plurality of second outlets. The plurality of third inlets and the plurality of second outlets are connected to the second confluence chamber. The plurality of third inlets are respectively connected to the plurality of first outlets, and the plurality of second outlets are respectively connected to the plurality of cleaning connectors 221.

[0067] Specifically, the diversion assembly 3 includes a primary diversion component 31 and multiple secondary diversion components 32. The primary diversion component 31 forms a first confluence chamber, serving as the initial collection and distribution center for the cleaning solution. The primary diversion component 31 is equipped with a first inlet and a second inlet, which are respectively connected to a first storage tank 21 and a second storage tank 23, allowing cleaning solutions from the two different storage tanks to enter the primary diversion component 31. Furthermore, the primary diversion component 31 also has multiple first outlets, which are connected to the first confluence chamber and used to disperse the collected cleaning solution to the next distribution stage.

[0068] Furthermore, to achieve more precise distribution of the cleaning solution, the diversion assembly 3 is also equipped with multiple secondary diversion components 32. Each secondary diversion component 32 has a second confluence chamber inside, serving as a further distribution center for the cleaning solution. The secondary diversion component 32 is equipped with multiple third inlets and multiple second outlets, which are respectively connected to the second confluence chambers. Importantly, the multiple third inlets are respectively connected to the multiple first outlets of the primary diversion component 31, thus allowing the cleaning solution from the primary diversion component 31 to be distributed to each of the secondary diversion components 32. The multiple second outlets are respectively connected to multiple cleaning connectors 221, realizing the final output of the cleaning solution from the diversion assembly 3 to the cleaning connectors 221.

[0069] By configuring the primary diversion component 31 and multiple secondary diversion components 32, the cleaning solution from the first storage tank 21 and the second storage tank 23 can be accurately distributed to each cleaning joint 221 as it flows through the primary diversion component 31 and multiple secondary diversion components 32. This improves the efficiency of the cleaning process and ensures that each cleaning joint 221 receives an appropriate amount of cleaning solution, achieving comprehensive, uniform and efficient cleaning of all parts of the negative pressure cleaning fixture 200.

[0070] Please see Figure 6 In some embodiments, a plurality of first liquid outlets are disposed on the lower surface of the primary diverter 31 and are arranged in a circular pattern; and / or, a plurality of second liquid outlets are disposed on the lower surface of the secondary diverter 32 and are arranged in a circular pattern.

[0071] Specifically, multiple first liquid outlets are provided on the lower surface of the primary diverter 31. These outlets are arranged in a circular pattern, allowing the cleaning solution to be evenly dispersed to each outlet after flowing through the primary diverter 31, and then precisely distributed to each secondary diverter 32. The circular arrangement makes the spacing between the multiple first liquid outlets more compact, thereby saving space occupied by the primary diverter 31 and making the entire cleaning equipment 100 more compact and efficient.

[0072] Similarly, multiple second liquid outlets are also provided on the lower surface of the secondary diversion component 32, and these second liquid outlets are also arranged in a circular pattern. This design allows the cleaning solution from the primary diversion component 31 to be further evenly distributed to each cleaning joint 221, ensuring the stability and efficiency of the cleaning process. At the same time, the circular arrangement of the second liquid outlets further saves the space occupied by the secondary diversion component 32, making the entire cleaning equipment 100 more compact and efficient.

[0073] Please see Figures 1 to 4In some embodiments, the driving component 13 includes a cylinder, a second bracket 12 is connected to the driving end of the cylinder, and a first bracket 11 is connected to the non-driving end of the cylinder. The cylinder can drive the second bracket 12 to move in the vertical direction, so that the second bracket 12 moves closer to or further away from the first bracket 11 in the vertical direction. The second bracket 12 also includes a support frame 121, a guide rod 122, and a guide sleeve 123. The guide sleeve 123 is disposed on the first bracket 11, and the guide rod 122 is movably inserted through the guide sleeve 123. The guide rod 122 is connected to the support frame 121, and the support frame 121 abuts against the driving end of the cylinder. The cylinder can drive the support frame 121 to move in the vertical direction.

[0074] The driving component 13 includes a cylinder, which drives the second bracket 12 to move by the driving force generated by the change of air pressure. The second bracket 12 is arranged opposite to the first bracket 11, wherein the second bracket 12 is movable, while the first bracket 11 remains stationary, and the second bracket 12 reciprocates in the vertical direction driven by the cylinder.

[0075] The second support 12 comprises a support frame 121, a guide rod 122, and a guide sleeve 123. The support frame 121, as the main body of the second support 12, supports the diversion assembly 3 and the cleaning assembly 22, and directly abuts against the drive end of the cylinder, receiving the driving force generated by the cylinder. The guide rod 122 is connected to one end of the support frame 121, and the other end is movably inserted into the guide sleeve 123. The guide sleeve 123 is fixed to the first support 11, providing a stable sliding channel for the guide rod 122. This design not only ensures the stability and straightness of the support frame 121 during movement but also improves the movement accuracy.

[0076] When the cylinder receives a drive signal, its drive end generates thrust or pull, which acts directly on the second support 12 through the support frame 121, causing the second support 12, including the support frame 121, guide rod 122, and other components, to move vertically. Due to the precise fit between the guide rod 122 and the guide sleeve 123, the movement of the support frame 121 will remain on a stable straight line, thus ensuring the accuracy and stability of the entire drive process.

[0077] Please see Figures 1 to 4 In some embodiments, the cleaning device 100 further includes a positioning mechanism 4 disposed on the first bracket 11. The positioning mechanism 4 is used to restrict the movement of the negative pressure cleaning fixture 200 in the horizontal direction so that the negative pressure cleaning fixture 200 is located in the cleaning position. When the negative pressure cleaning fixture 200 is located in the cleaning position, the cleaning connector 221 corresponds to the liquid injection component 202 of the negative pressure cleaning fixture 200 in the moving direction of the cleaning mechanism 2.

[0078] The main function of the positioning mechanism 4 is to restrict the horizontal movement of the negative pressure cleaning fixture 200, ensuring that the negative pressure cleaning fixture 200 remains fixed throughout the cleaning process and does not shift or move due to external forces or internal pressure. By restricting the movement of the negative pressure cleaning fixture 200, the positioning mechanism 4 ensures that the cleaning connector 221 can accurately align with the liquid injection component 202, thereby preventing leakage, optimizing the cleaning effect, and protecting the cleaning equipment 100 and the negative pressure cleaning fixture 200 from damage.

[0079] Optionally, the positioning mechanism 4 may have adjustable positioning points or clamping devices to adapt to the positioning of negative pressure cleaning fixtures 200 of different sizes and shapes, ensuring the versatility of the cleaning equipment 100.

[0080] In addition, the positioning mechanism 4 may include at least two positioning members, which are spaced apart on the first bracket 11 along the first horizontal direction. The positioning members are used to abut against the negative pressure cleaning fixture 200. One of the positioning members can be controllably moved along the first horizontal direction to cooperate with the other positioning member to clamp or release the negative pressure cleaning fixture 200.

[0081] The positioning mechanism 4 includes at least two positioning elements, which are spaced apart on the first bracket 11 along a first horizontal direction. Each positioning element is designed with a contact surface that matches the negative pressure cleaning fixture 200. When the positioning element abuts against the negative pressure cleaning fixture 200, it forms a stable support point, ensuring that the negative pressure cleaning fixture 200 will not shift or shake due to external forces during the cleaning process, thereby improving the accuracy and stability of the cleaning.

[0082] One of the positioning components is designed to move controllably along a first horizontal direction. This means that the positioning component can not only provide support in a fixed position, but also be finely adjusted according to actual needs, so that the positioning mechanism 4 can flexibly adapt to negative pressure cleaning fixtures 200 of different sizes or shapes, achieving wider applicability.

[0083] When it is necessary to clamp the negative pressure cleaning fixture 200, the operator can control the movable positioning component to move it to a position opposite to another fixed positioning component. Then, the two positioning components cooperate to clamp the negative pressure cleaning fixture 200, ensuring the stability of the negative pressure cleaning fixture 200 during the cleaning process.

[0084] Conversely, when it is necessary to release the negative pressure cleaning fixture 200, the operator only needs to control the movable positioning component to move in the opposite direction, separating it from the fixed positioning component. In this way, the negative pressure cleaning fixture 200 can be easily removed from or placed on the first support 11.

[0085] In some embodiments, a plurality of first check valves are respectively provided inside the plurality of cleaning connectors 221. The first check valves can control the opening and closing of the cleaning connectors 221 and prevent the cleaning solution in the cleaning connectors 221 from flowing to the diversion assembly 3 when the first check valves are open.

[0086] Each cleaning connector 221 is equipped with multiple first check valves. When the check valves are open, the cleaning solution is allowed to flow out of the cleaning connector 221 to clean the negative pressure cleaning fixture 200. Simultaneously, the check valves effectively prevent the cleaning solution inside the cleaning connector 221 from flowing back towards the diversion assembly 3.

[0087] During the cleaning process, the cleaning solution is distributed from the storage tank to each cleaning connector 221 via the distribution assembly 3. If the cleaning solution could flow back to the distribution assembly 3, it would not only reduce the cleaning efficiency but also potentially cause unnecessary damage to the distribution assembly 3. Therefore, the introduction of the first one-way valve effectively solves this problem, allowing the cleaning solution to flow along a predetermined path and flow rate, thereby improving the accuracy and efficiency of the cleaning process.

[0088] In some embodiments, a plurality of first check valves are respectively provided inside the plurality of cleaning connectors 221. The first check valves can control the opening and closing of the cleaning connectors 221 and prevent the cleaning solution in the cleaning connectors 221 from flowing to the diversion assembly 3 when the first check valves are open.

[0089] The first check valve can be configured as a push-button check valve. The working principle of the push-button check valve is based on the elasticity of the spring and the pressure of the fluid. When the liquid injection part 202 of the negative pressure cleaning fixture 200 is connected to the cleaning connector 221 of the cleaning machine, the center part of the liquid injection part 202 will contact the trigger part of the first check valve and generate a certain pressure. This pressure is sufficient to overcome the elasticity of the spring, causing the valve disc of the first check valve to open, thereby allowing the cleaning solution to flow out from the cleaning connector 221 to clean the negative pressure cleaning fixture 200.

[0090] Furthermore, during the cleaning process, the cleaning solution continuously flows to the tooling through the open first one-way valve, ensuring thorough and uniform cleaning. When the tooling is disconnected from the cleaning machine, the valve disc of the first one-way valve quickly closes under the force of the spring, cutting off the flow path of the cleaning solution and preventing dripping and leakage after disconnection, thus maintaining a clean and safe working environment.

[0091] In addition, the push-button check valve also has a certain explosion-proof function. During the cleaning process, if excessive pressure is generated inside the cleaning system due to excessively high cleaning solution temperature or pressure, the valve disc of the first check valve will automatically open under the pressure to release the excessive pressure, thereby preventing dangerous situations such as system explosion.

[0092] Similarly, a second check valve can also be installed inside the liquid injection part 202 of the negative pressure cleaning fixture 200. The second check valve can also be set as a push-button check valve. The beneficial effects of the second check valve and the first check valve are the same, and will not be elaborated here.

[0093] Please see Figure 5 and Figure 6 In some embodiments, the negative pressure cleaning fixture 200 further includes a first liquid outlet 203, a first air inlet 204, and a first negative pressure interface 205, which are respectively connected to the overflow chamber 201.

[0094] The cleaning equipment 100 also includes a second liquid outlet 51, which is connected to the first liquid outlet 203 through a first liquid outlet pipe 511. The second liquid outlet 51 is used to discharge the cleaning medium in the overflow chamber 201. The first liquid outlet pipe 511 is provided with a first liquid outlet valve 512, which is used to control the opening and closing of the first liquid outlet pipe 511.

[0095] The second air intake port 52 is connected to the first air intake port 204 through the first air intake pipe 521. The second air intake port 52 is used to connect the overflow chamber 201 to the atmosphere. The first air intake pipe 521 is provided with a first air intake valve 522, which is used to control the opening and closing of the first air intake pipe 521.

[0096] The second negative pressure interface 53 is connected at one end to the first negative pressure interface 205. The second negative pressure interface 53 is used to connect the overflow chamber 201 to the negative pressure generating element. The first negative pressure pipeline 531 is provided with a first negative pressure valve 532, which is used to control the opening and closing of the first negative pressure pipeline 531.

[0097] The negative pressure cleaning fixture 200 is connected to the drain, the atmosphere and the negative pressure generator through the cleaning equipment 100, so that the cleaning solution inside the negative pressure cleaning fixture 200 can be discharged from the second liquid outlet 51, and the overflow chamber 201 of the negative pressure cleaning fixture 200 is connected to the atmosphere through the second air inlet 52, and at the same time connected to the negative pressure generator through the second negative pressure outlet 53, so that the negative pressure generated by the negative pressure generator can act on the overflow chamber 201.

[0098] Please see Figure 7 , Figure 7The diagram below shows the piping of the cleaning device 100 provided in the embodiments of this application. In some embodiments, the first liquid storage tank 21 and the diversion component 3 are connected by a first connecting pipe. The first connecting pipe is provided with a first connecting valve 711, which can control the opening and closing of the first connecting pipe between the first liquid storage tank 21 and the diversion component 3.

[0099] The first storage tank 21 and the diversion assembly 3 are connected by a first connecting pipe, and a first connecting valve 711 is installed on the first connecting pipe. The first connecting valve 711 is responsible for controlling whether the cleaning solution flows between the first storage tank 21 and the diversion assembly 3, that is, it can open or close the first connecting pipe.

[0100] Specifically, when the first connecting valve 711 is open, the cleaning solution in the first storage tank 21 can flow to the diversion assembly 3 through the first connecting pipe. In this way, the diversion assembly 3 can distribute the cleaning solution to multiple cleaning connectors 221. When the first connecting valve 711 is closed, the flow of the cleaning solution in the first connecting pipe is cut off, and the cleaning solution in the first storage tank 21 can no longer flow to the diversion assembly 3, thus achieving control over the flow of the cleaning solution.

[0101] In this way, the first connecting valve 711 can control the flow of the cleaning solution to avoid unnecessary waste and pollution, improve the utilization efficiency of the cleaning solution, and help ensure the safety and stability of the cleaning equipment 100, preventing potential risks caused by improper flow of the cleaning solution.

[0102] Please see Figure 7 In some embodiments, the second liquid storage tank 23 and the diversion component 3 are connected by a second connecting pipe, and the second connecting pipe is provided with a second connecting valve 721, which can control the opening and closing of the second connecting pipe between the second liquid storage tank 23 and the diversion component 3.

[0103] The second storage tank 23 and the diversion assembly 3 are connected by a second connecting pipe, and a second connecting valve 721 is installed on the second connecting pipe. The second connecting valve 721 is responsible for controlling whether the cleaning solution flows between the second storage tank 23 and the diversion assembly 3, that is, it can open or close the second connecting pipe.

[0104] Specifically, when the second connecting valve 721 is open, the cleaning solution in the second storage tank 23 can flow to the diversion assembly 3 through the second connecting pipe. In this way, the diversion assembly 3 can distribute the cleaning solution to multiple cleaning connectors 221. When the second connecting valve 721 is closed, the flow of the cleaning solution in the second connecting pipe is cut off, and the cleaning solution in the second storage tank 23 can no longer flow to the diversion assembly 3, thus achieving control over the flow of the cleaning solution.

[0105] In this way, the second connecting valve 721 can control the flow of the cleaning solution to avoid unnecessary waste and pollution, improve the utilization efficiency of the cleaning solution, and help ensure the safety and stability of the cleaning equipment 100, preventing potential risks caused by improper flow of the cleaning solution.

[0106] Please see Figures 8 to 11 , Figure 8 This is one of the structural schematic diagrams of the cabinet 8 provided in the embodiments of this application; Figure 9 This is the second structural schematic diagram of the cabinet 8 provided in the embodiments of this application; Figure 10 This is the third structural schematic diagram of the cabinet 8 provided in the embodiments of this application; Figure 11 This is a fourth structural schematic diagram of the cabinet 8 provided in an embodiment of this application. In some embodiments, the cleaning device 100 further includes: a cabinet 8, the interior of which forms a receiving space for accommodating the positioning mechanism 4 and the cleaning mechanism 2.

[0107] The cabinet 8 has an internal storage space. The main function of this storage space is to accommodate the positioning mechanism 4 and the cleaning mechanism 2, thereby ensuring that the entire cleaning process can be carried out in a closed and orderly environment.

[0108] Meanwhile, the cleaning equipment 100 is equipped with an independent electrical cabinet 83, that is, the electrical components, triplet assemblies and other components used in the cleaning equipment 100 are all installed inside the independent electrical cabinet 83, which is separate from other components inside the cabinet 8. In this way, when a fire occurs inside the cabinet 8, it can prevent the fire from spreading to the inside of the electrical cabinet.

[0109] Optionally, the cabinet 8 can be designed with auxiliary functions such as ventilation and drainage. Ventilation helps to reduce the temperature and humidity inside the cabinet 8, maintaining a suitable cleaning environment and removing harmful gases generated during the cleaning process. The drainage system is responsible for timely discharge of waste liquid generated during the cleaning process, preventing damage to the cleaning equipment 100 and the negative pressure cleaning fixture 200.

[0110] In addition, the cabinet 8 may be equipped with a fire door assembly 81, which provides a passage for pallet entry and exit, and in the event of a fire inside the cabinet 8, the fire door will automatically close to contain the spread of the fire. The cabinet 8 may also be equipped with a maintenance door assembly 82, which may be located on the surface of the cabinet 8 away from the fire door assembly 81, to facilitate maintenance of components inside the cabinet 8 that are away from the fire door.

[0111] Please see Figure 7In some embodiments, the cleaning device 100 further includes: a second negative pressure pipeline 54, one end of which is connected to a negative pressure generating element, the other end of which is connected to a second liquid storage tank 23, the second negative pressure pipeline 54 being connected to a first negative pressure pipeline 531, and a second negative pressure valve 541 being provided on the second negative pressure pipeline 54 for controlling the opening and closing of the second negative pressure pipeline 54.

[0112] The design of the second negative pressure pipeline 54 enables the negative pressure generated by the negative pressure generator to be transmitted to the second liquid storage tank 23, thereby facilitating the extraction of the cleaning solution from the second liquid storage tank 23. To ensure the controllability of this process, a second negative pressure valve 541 is installed on the second negative pressure pipeline 54. The second negative pressure valve 541 can control the opening and closing of the pipeline as needed, thereby regulating the transmission of negative pressure.

[0113] Please see Figure 7 In some embodiments, the first liquid storage tank 21 is connected to the liquid supply source through the liquid supply pipeline 55. The liquid supply source provides cleaning solution to the first liquid storage tank 21 through the liquid supply pipeline 55. The liquid supply pipeline 55 is provided with a liquid supply switch valve 551, which is used to control the opening and closing of the liquid supply pipeline 55.

[0114] Specifically, the liquid supply source acts as the provider of the cleaning solution, delivering the required cleaning solution to the first storage tank 21 through the liquid supply pipeline 55. The liquid supply pipeline 55 is equipped with a liquid supply switch valve 551, which can control the opening and closing of the liquid supply pipeline 55 according to actual needs, thereby regulating the flow of the cleaning solution. When cleaning operations are required, the liquid supply switch valve 551 is opened, and the cleaning solution flows through the liquid supply pipeline 55 under the action of the liquid supply source, entering the first storage tank 21. When cleaning operations are paused or completed, the liquid supply switch valve 551 closes promptly, ensuring that the liquid in the liquid supply pipeline 55 is not lost. The liquid supply switch valve 551 not only realizes the delivery of the cleaning solution but also improves the operational flexibility and resource utilization efficiency of the cleaning equipment 100.

[0115] Please see Figure 7 In some embodiments, the first liquid storage tank 21 discharges the gas inside the first liquid storage tank 21 through the exhaust pipe 64. The exhaust pipe 64 is provided with an exhaust valve 641, which is used to control the opening and closing of the exhaust pipe 64.

[0116] When the first liquid storage tank 21 needs to be vented, the vent valve 641 will be opened, allowing the gas in the first liquid storage tank 21 to be discharged through the vent pipe 64, so as to maintain the stability of the internal pressure of the first liquid storage tank 21, prevent gas accumulation, and ensure the quality and purity of the cleaning solution.

[0117] When the venting demand is met, or to prevent gas loss and maintain the seal of the first liquid storage tank 21, the vent valve 641 will close. In this way, the opening and closing operation of the vent valve 641 constitutes an effective gas management system, which not only ensures the normal operation of the first liquid storage tank 21, but also improves the efficiency and reliability of the entire cleaning equipment 100.

[0118] Please see Figure 7 In some embodiments, the first storage tank 21 discharges the cleaning solution inside the first storage tank 21 through the first drain pipe 56. The first drain pipe 56 is provided with a first drain valve 561, which is used to control the opening and closing of the first drain pipe 56. The second storage tank 23 discharges the cleaning solution inside the second storage tank 23 through the second drain pipe 57. The second drain pipe 57 is provided with a second drain valve 571, which is used to control the opening and closing of the second drain pipe 57.

[0119] The first storage tank 21 discharges the cleaning solution inside through the first drain pipe 56. A first drain valve 561 is installed on the first drain pipe 56, the main function of which is to control the opening and closing of the first drain pipe 56. When it is necessary to discharge the cleaning solution from the first storage tank 21, the operator opens the first drain valve 561, allowing the cleaning solution to flow smoothly through the first drain pipe 56. When the discharge task is completed or discharge needs to be paused, the first drain valve 561 is closed to ensure that the solution in the first storage tank 21 does not leak out.

[0120] Similarly, the second storage tank 23 discharges the cleaning solution inside through the second drain pipe 57. A second drain valve 571 is installed on the second drain pipe 57, the main function of which is to control the opening and closing of the second drain pipe 57. When it is necessary to discharge the cleaning solution from the second storage tank 23, the operator opens the second drain valve 571, allowing the cleaning solution to flow smoothly out through the second drain pipe 57. When the discharge task is completed or the discharge needs to be paused, the second drain valve 571 is closed to ensure that the solution in the second storage tank 23 does not leak out.

[0121] Please see Figure 7In some embodiments, the cleaning device 100 further includes: a first atmospheric conduit 61, one end of which is connected to a first liquid storage tank 21, and the other end of which is connected to external clean air; a first atmospheric switch valve 611, disposed on the first atmospheric conduit 61, for controlling the opening and closing of the first atmospheric conduit 61; a second atmospheric conduit 62, one end of which is connected to a second liquid storage tank 23, and the other end of which is connected to external clean air; and a second atmospheric switch valve 621, disposed on the second atmospheric conduit 62, for controlling the opening and closing of the second atmospheric conduit 62.

[0122] One end of the first atmospheric duct 61 is connected to the interior of the first liquid storage tank 21, while the other end leads to the outside, ensuring that the first liquid storage tank 21 can obtain uncontaminated air. To precisely control the opening and closing of the first atmospheric duct 61, a first atmospheric switch valve 611 is installed on it. When it is necessary to introduce clean external air into the first liquid storage tank 21, the first atmospheric switch valve 611 is opened, allowing air to enter the first liquid storage tank 21 through the first atmospheric duct 61. When it is not necessary to introduce air or to maintain the airtightness of the first liquid storage tank 21, the first atmospheric switch valve 611 is closed promptly.

[0123] Similarly, one end of the second atmospheric conduit 62 is connected to the interior of the second liquid storage tank 23, while the other end leads to the outside, ensuring that the second liquid storage tank 23 can obtain uncontaminated air. To precisely control the opening and closing of the second atmospheric conduit 62, a second atmospheric switch valve 621 is installed on it. When it is necessary to introduce clean external air into the second liquid storage tank 23, the second atmospheric switch valve 621 is opened, allowing air to enter the second liquid storage tank 23 through the second atmospheric conduit 62. When it is not necessary to introduce air or to maintain the airtightness of the second liquid storage tank 23, the second atmospheric switch valve 621 is closed promptly.

[0124] Please see Figure 7 In some embodiments, the cleaning device 100 further includes: a third atmospheric duct 63, one end of which is connected to the diversion component 3 and the other end of which is connected to external clean air; and a third atmospheric switch valve 631, which is disposed in the third atmospheric duct 63 and is used to control the opening and closing of the third atmospheric duct 63.

[0125] The third atmospheric duct 63 connects the diversion assembly 3 to the external clean air. The third atmospheric switch valve 631 allows the operator to flexibly control the opening and closing of the third atmospheric duct 63 according to actual needs, thereby regulating the air entering the diversion assembly 3.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
