When the latch 235 is in the second position, refer to Fig.12, the plug-in device 32 is unlocked from the latch 235, so that the vacuum device unit 3 is released from the base 23, and the vacuum device unit 3 can be pulled out from the base 23. Preferably, a handle 2354 is provided at the front end of the latch 235, and the handle 2354 extends out of the base 23. By providing the handle 2354, the user can more conveniently pull the latch 235 to slide the latch 235 between the first position and the second position.

[0021] Preferably, in this embodiment, refer to Fig.10 The plug-in device 32 includes a first plug portion 321, a second plug portion 322 and a third plug portion 323. The first plug portion 321 is arranged between the second plug portion 322 and the third plug portion 323. The plug interface includes a first socket 232 and a second socket 234. The first plug portion 321 is plugged with the first socket 232, and the third plug portion 323 is plugged with the second socket 234. Preferably, in this embodiment, a signal interface C2313 is provided in the second socket 234, and a signal interface D3231 is provided on the third plug portion 323. A limiting step 233 that is limitedly matched with the second plug portion 322 is provided on the base 23. The bottom side of the first plug portion 321 is provided with a locking plate 234 arranged along the sliding direction of the latch 235.

The lock latch 235 is provided with a first locking opening 2351 which is locked with the locking slot 3211. Specifically, the first locking opening 2351 includes a large opening end 23511 for the locking slot 3211 to enter and a small opening end 23512 which is locked with the locking slot 3211. The large opening end 23511 is communicated with the small opening end 23512. When the lock latch 235 is located at the first position, the locking slot 3211 is locked with the small opening end 23512. When the lock latch 235 is located at the second position, the locking slot 3211 escapes from the small opening end 23512 and enters the large opening end 23511, and the lock slot 3211 is unlocked from the first locking opening 2351.

[0022] Preferably, the second plug portion 322 is provided with a locking buckle 3221, and the latch 235 is provided with a second locking hole 2352 that is locked and matched with the locking buckle 3221.

After entering the second locking opening 2352, the locking buckle 3221 recovers under the action of its own elastic force to achieve the locking function. The setting of the guide slope makes it easier for the locking buckle 3221 to drive the protrusion to insert into the second locking opening 2352, and the setting of the locking slope is used to lock with the second locking opening 2352. In a further embodiment, the inclination angle of the locking slope is larger than the inclination angle of the guide slope, so that the locking slope can achieve locking cooperation with the second locking opening 2352, so that the latch 235 remains in a state of locking cooperation with the locking buckle 3221.

When the vacuum valve 342 is working, the positive-pressure gas is evacuated through the negative pressure generating mechanism to generate negative pressure. The negative-pressure gas is then connected to the vacuum connector 332. When the air-breaking valve 343 is working, the positive-pressure gas is connected to the vacuum connector 332 to break the air. The excess gas in the vacuum generator unit is then discharged from the second vent 213 through the second confluence chamber 2371.

[0034] When the vacuum equipment unit 3 is a vacuum pump unit, the negative pressure gas in the second confluence chamber 2371 enters the vacuum pump unit and connects with the vacuum valve 342, and the positive pressure gas in the first confluence chamber 2361 enters the vacuum pump unit and connects with the air piercing valve 343. When the vacuum valve 342 is working, the negative pressure gas is connected with the vacuum connector 332. When the air piercing valve 343 is working, the positive pressure gas is connected with the vacuum connector 332 to pierce the air.

[0035] Preferably, in this embodiment, a third gas channel is provided between the venting valve 343 and the vacuum connector 332, and a throttle valve 333 is provided on the vacuum equipment unit 3. The throttle valve 333 extends into the third gas channel, and the flow rate of the venting gas is adjusted by the throttle valve 333.

[0036] Preferably, in this embodiment, the pressure gauge module 35 is provided with the unit circuit board 31. Fig.16 - Fig.18 The vacuum pilot valve 344 and the air-breaking pilot valve 345 are provided with an electromagnetic coil and a pin 346 electrically connected to the electromagnetic coil. The unit circuit board 31 is integrated with a socket 351 corresponding to the pin 346. The pin 346 and the socket 351 are plugged together to make the electromagnetic coil electrically connected to the unit circuit board 31. This design does not require the use of complex wiring harness connections during the installation process, thereby simplifying the entire installation process and shortening the time required for installation. Through this wiring harness-free connection method, not only the convenience of installation is improved, but also the stability and reliability of the connection are significantly improved.

[0037] Specifically, the traditional wiring harness connection method requires connecting multiple wiring harnesses to the electromagnetic coil and the unit circuit board 31 respectively, which is not only time-consuming and labor-intensive, but also prone to connection errors or poor contact problems. With the adopted wiring harness-free connection method, the user only needs to align the pin 346 with the socket 351 and gently plug it in to complete the connection without the need for complicated wiring operations. In addition, the traditional wiring harness connection method is prone to poor contact or broken wires due to bending, pulling or vibration of the wiring harness, thereby affecting the normal operation of the equipment. The pin 346 and the socket 351 fit closely together, and the connection relationship is stable, which can effectively avoid the risks brought by poor contact or broken wires, thereby ensuring the reliable operation of the equipment. When inspection and maintenance are required, maintenance personnel can quickly disassemble and reconnect the equipment, which improves maintenance efficiency and shortens maintenance time.

[0038] The pressure gauge module 35 is provided with a pressure sensor, which is electrically connected to the unit circuit board 31. The detection end of the pressure sensor extends into the main body module 33 to detect the pressure in the main body module 33 to ensure that it works within a reasonable pressure range.

[0039] Preferably, in this embodiment, the valve assembly module 34 is provided with a wedge-shaped positioning block 341, and the main body module 33 is provided with a wedge-shaped positioning groove 331 corresponding to the wedge-shaped positioning block 341, which is convenient for quick and accurate positioning during the assembly process, thereby improving production efficiency and assembly quality. Through the cooperation between the wedge-shaped positioning block 341 and the wedge-shaped positioning groove 331, the valve assembly module 34 can be effectively prevented from being displaced or loosened during use, thereby ensuring the stable operation of the equipment.

[0040] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
