While this enhances the overall sealing of the equipment, it also brings many inconveniences when maintaining or replacing the negative pressure cups. Since the negative pressure cups are fixedly connected to the outer shell, when maintenance or replacement of the negative pressure cups is required, the entire component must be disassembled, leading to unnecessary material waste. This utility model proposes an integrated negative pressure component.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] The present application will be further described in detail below with reference to Figures 1-6.
[0024] This application discloses an integrated negative pressure assembly. Referring to Figures 1, 2, and 4, an integrated negative pressure assembly includes a housing 1, a negative pressure cup 2 disposed on the inner wall of the housing 1, and two limiting mechanisms 3 disposed on the inner wall of the housing 1.
[0025] The limiting mechanism 3 includes a locking block 301, which is fixedly connected to both sides of the negative pressure cup 2. A connecting groove 306 is provided on the inner wall of the outer shell 1. The surface of the locking block 301 contacts the inner wall of the connecting groove 306. One side of the connecting groove 306 is connected to a limiting groove 305. A connecting rod 304 is fixedly connected to the inner wall of the limiting groove 305. A limiting block 302 is rotatably connected to the surface of the connecting rod 304. The surface of the limiting block 302 contacts the surface of the locking block 301. A locking groove 303 is provided on the top of the limiting block 302. The locking block 301 and the locking groove 303... When used together, by setting a limiting mechanism 3, a locking block 301 and a limiting block 302 are set between the negative pressure cup 2 and the outer shell 1. By inserting the locking block 301 into the locking groove 303 of the limiting block 302, the negative pressure cup 2 can be firmly fixed to the outer shell 1. When it is necessary to disassemble the negative pressure cup 2 for maintenance or replacement, it is only necessary to release the locking state between the locking block 301 and the locking groove 303, and the negative pressure cup 2 can be removed as a whole. There is no need to disassemble the entire integrated negative pressure component on a large scale, making the negative pressure cup 2 an independently replaceable module, which is beneficial for later maintenance.
[0026] Referring to Figures 5 and 6, a sliding groove 9 is provided on the inner wall of the outer casing 1. One end of the sliding groove 9 is connected to one side of the limiting groove 305, and one side of the sliding groove 9 is connected to a movable groove 10. By setting the sliding groove 9 and the movable groove 10, the connection between the limiting block 302 and the locking block 301 can be provided with a movable space, ensuring good stability of the limiting block 302 and the locking block 301 during the locking process.
[0027] Referring to Figures 3 and 4, a support rod 4 is slidably connected to the inner wall of the slide groove 9. One end of the support rod 4 contacts the bottom of the limiting block 302, and the other end of the support rod 4 is provided with a groove 5. By setting the support rod 4, the locked limiting block 302 and the locking block 301 can be supported and fixed, preventing the limiting block 302 and the locking block 301 from accidentally disengaging due to external factors, thus improving the locking stability and safety. The groove 5 provides a convenient operating space for the user to easily remove the support rod 4.
[0028] Referring to Figure 3, a positioning block 6 is fixedly connected to one end of the support rod 4. Positioning slots 11 are provided on both sides of the positioning block 6. By setting the positioning block 6 and the positioning slots 11, the support rod 4 can be connected to the outer shell 1, ensuring the accuracy of the support rod 4 during installation.
[0029] Referring to Figure 6, an elastic block 7 is fixedly connected to the inner wall of the movable groove 10. The inner wall of the elastic block 7 is in contact with the surface of the positioning block 6. Positioning posts 8 are fixedly connected to both ends of the elastic block 7. The surface of the positioning posts 8 is in contact with the inner wall of the positioning groove 11. By setting the elastic block 7 and the positioning posts 8, the positioning block 6 can be locked to prevent the support rod 4 from shifting or falling off when supporting the limit block 302 and the locking block 301, thus ensuring the stability of the support rod 4.
[0030] Referring to Figure 4, a spring 12 is provided between the bottom of the limiting block 302 and the inner wall of the limiting groove 305. One end of the spring 12 is fixedly connected to the bottom of the limiting block 302, and the other end of the spring 12 is fixedly connected to the inner wall of the limiting groove 305. By providing the spring 12, the spring 12 stores elastic potential energy after being compressed, and can automatically release energy after the external force is removed, so that the limiting block 302 automatically returns to the initial position.
[0031] Working Principle: The integrated negative pressure component uses an electronically controlled vacuum generator to adsorb target objects. In its structural design, a parallel power module provides stable power to the entire system, with current distributed through positive and negative busbars. The integrated negative pressure cup 2 serves as the core actuator, internally connected to a miniature vacuum pump via an air path. Upon startup, this pump removes air, creating a localized low-pressure area that generates suction force at the suction nozzle. The probe module mounting plate can accommodate various sensors or detection probes to monitor the negative pressure status, adsorption effect, and electrical signal feedback from the adsorbed object in real time. This is existing technology and will not be elaborated further. When maintenance or replacement of the negative pressure cup 2 is required, the user opens the outer casing 1 to expose the internal structure, using the grooves on the support rod 4... 5. The user can easily apply force using the groove 5 to pull the support rod 4 outward. At this time, the positioning block 6 disengages from the elastic block 7 and the positioning post 8, allowing the support rod 4 to be pulled out. As the support rod 4 moves, the end of the support rod 4 will disengage from the support of the limiting block 302. The bottom of the limiting block 302 loses support. Without external force restriction, the negative pressure cup 2 is no longer locked by the limiting structure 3, and the user can pull out the negative pressure cup 2 for disassembly. After replacement, the user aligns the replaced negative pressure cup 2 with the installation position of the outer shell 1, and passes the locking block 301 through the connecting groove 306. As the negative pressure cup 2 is gradually pushed into the outer shell 1, the front end of the locking block 301 will contact the surface of the limiting block 302 and apply pressure. Driven by the push of 1, the limiting block 302 will rotate downward around the connecting rod 304 as the fulcrum. At this time, the spring 12 will be compressed, thereby storing elastic potential energy. The downward movement of the limiting block 302 allows the locking block 301 to fully enter the connecting groove 306. At this time, the locking block 301 will disengage from the front end of the limiting block 302, thereby releasing the pressure applied to the limiting block 302. The compressed spring 12 can rebound, causing the limiting block 302 to return to its original position. At this time, the locking block 301 will enter the locking groove 303 of the limiting block 302. The engagement of the locking block 301 and the limiting block 302 can limit the negative pressure cup 2. Then, the user inserts the support rod 4 through the sliding groove 9. As the support rod 4 enters, the front end of the positioning block 6 will contact the positioning post 8. The pressure applied to the positioning post 8 and the elastic block 7 causes the elastic block 7, which was originally in a closed state, to deform and open outward, making room for the positioning block 6 to enter. When the positioning block 6 continues to advance and fully enters the interior of the elastic block 7, the positioning groove 11 on the surface of the positioning block 6 provides a springback space for the opened positioning post 8, causing the opened elastic block 7 to spring back and drive the positioning post 8 to lock into the positioning groove 11 on the positioning block 6, thereby locking the positioning block 6. At this time, the support rod 4 will fully enter the slide groove 9, and the end of the support rod 4 will contact the bottom of the limit block 302, thereby supporting the bottom of the limit block 302. The support rod 4 can lock the locking block 301 and the limit block 302, ensuring the stability of the installation.

The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
