Abstract
Description
Technical Field
[0001] This specification relates to the field of vacuum generator technology, and particularly to a vacuum generator assembly and a modular vacuum generator. Background Technology
[0002] A vacuum generator is a new type of efficient, clean, economical, and compact vacuum component that uses a positive pressure air source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure in places where compressed air is available, or in a pneumatic system where both positive and negative pressure are required simultaneously. The traditional application of vacuum generators is in conjunction with suction cups for the adsorption and handling of various materials, especially suitable for adsorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects. Vacuum generators are widely used in industrial automation in fields such as machinery, electronics, packaging, printing, plastics, and robotics.
[0003] A typical vacuum generator assembly has two solenoid valves (including a supply valve and a vacuum breaking valve), manual pins for both solenoid valves, and a pressure switch. In the prior art, the pressure switch and the manual pins for the two solenoid valves are usually set as independent components. The pressure switch and the manual pins are designed in different directions, which can easily lead to misoperation during debugging and makes debugging very inconvenient.
[0004] There is currently no effective solution to the above problems. Utility Model Content
[0005] This specification provides a vacuum generator assembly and a containerized vacuum generator to solve the problem in the prior art where the pressure switch and manual pin are designed in different directions, making debugging easy to misoperate and inconvenient.
[0006] This specification provides a vacuum generator assembly, including: a main valve body, a pilot solenoid valve assembly, a breaker valve, a supply valve, a pressure switch assembly, a breaker valve manual pin, and a supply valve manual pin. The breaker valve, the supply valve, and the pilot solenoid valve assembly are arranged at intervals along a first direction within the main valve body. The pilot solenoid valve assembly includes a breaker pilot valve and a supply pilot valve. The breaker pilot valve controls the opening and closing of the breaker valve, and the supply pilot valve controls the opening and closing of the supply valve. The pressure switch assembly includes a PCB board and an integrated operation panel. The integrated operation panel and the PCB board are fixed to a first side of the main valve body. The integrated operation panel covers the PCB board. The PCB board and the pilot solenoid valve assembly are connected. The valve assembly is electrically connected to control the on / off state of the pilot solenoid valve assembly. The integrated operation panel has a pressure regulating panel and two first through holes. The pressure regulating panel is located on one side of the pilot solenoid valve assembly. The PCB board has two second through holes, with each first through hole corresponding to one second through hole. The first side of the main valve body faces the breaker valve, the supply valve, and the pilot solenoid valve assembly. The breaker valve manual pin and the supply valve manual pin are movably fixed to the integrated operation panel through the first and second through holes, so as to push the valve core of the breaker valve to move horizontally when the breaker valve manual pin is moved downward by external force, or to push the valve core of the supply valve to move horizontally when the supply valve manual pin is moved downward by external force.
[0007] In one embodiment of this application, it further includes: an air supply port, a vacuum port, and an exhaust port, wherein the air supply port and the vacuum port are disposed on the second side of the main valve body near the rupture valve, and the exhaust port is disposed on the third side opposite to the second side in the indicated first direction.
[0008] In one embodiment of this application, the vacuum generator assembly further includes: a vacuum generator, which is horizontally arranged and located below the pilot solenoid valve assembly. The inlet end of the vacuum generator is located below the supply valve, and the outlet end of the vacuum generator is connected to the exhaust port. A first air passage is formed between the air supply port and the supply valve, a second air passage is formed between the supply valve and the inlet end of the vacuum generator, and a third air passage is formed between the inlet end of the vacuum generator and the exhaust port. When the valve core of the supply valve is open, the first air passage, the second air passage, and the third air passage are connected. A fourth air passage is formed between the vacuum port and the outlet end of the vacuum generator.
[0009] In one embodiment of this application, a fifth gas path is formed between the gas supply port and the breaker valve, and a sixth gas path is formed between the breaker valve and the vacuum port. When the valve core of the breaker valve is opened, the fifth gas path and the sixth gas path are connected.
[0010] In one embodiment of this application, the vacuum generator assembly further includes a flow regulating valve disposed on the sixth gas path, the flow regulating valve being used to regulate the flow rate of the sixth gas path.
[0011] In one embodiment of this application, the vacuum generator assembly further includes a pressure regulating valve, which is fixed at the air supply port and is used to regulate the air source pressure at the air supply port.
[0012] In one embodiment of this application, the manual pin of the breaker valve has a first ramp guide surface at the end near the breaker valve, and the manual pin of the supply valve has a second ramp guide surface at the end near the supply valve.
[0013] In one embodiment of this application, the vacuum generator assembly further includes a silencing assembly, which comprises a silencing plate and a silencing housing. The silencing housing is fixed to the exhaust port of the vacuum generator assembly. The silencing housing has at least five walls, and at least four walls are provided with perforated grids for exhaust. The perforated grids are used for exhaust. The silencing plate abuts against the inner wall of the silencing housing and at least covers the perforated grids.
[0014] In one embodiment of this application, the sound-absorbing sheet is an integral structure, and / or the sound-absorbing sheet is made of high molecular weight polyethylene material.
[0015] This specification also provides a containerized vacuum generator, including multiple of the above-described vacuum generator components.
[0016] This specification provides a vacuum generator assembly, which may include a main valve body, a pilot solenoid valve assembly, a breaker valve, a supply valve, a pressure switch assembly, a breaker valve manual pin, and a supply valve manual pin. Since the pilot solenoid valve assembly typically needs to be connected to the pressure switch assembly, the pressure switch assembly can control the on / off state of the pilot solenoid valve assembly via an adjustment button, thereby controlling the opening and closing of the breaker valve and supply valve to regulate the pressure within the vacuum generator assembly. Furthermore, the breaker valve manual pin and supply valve manual pin are typically corresponding to the breaker valve and supply valve. Therefore, the breaker valve, supply valve, and pilot solenoid valve assembly can be arranged at intervals along a first direction within the main valve body. Correspondingly, the pressure switch assembly, breaker valve manual pin, and supply valve manual pin can also be arranged at intervals along the first direction, allowing them to be positioned in the same direction within the main valve body. When manual adjustment is required, the user can see the pressure changes displayed on the pressure switch assembly in real time, enabling more convenient and precise adjustment and avoiding misoperation. Furthermore, the pressure switch assembly that is automatically adjusted by a button can be integrated with the manual pins of the rupture valve and the supply valve. The pressure switch assembly can include a PCB board and an integrated operation panel. The integrated operation panel has a pressure regulating panel and two first through holes. The pressure regulating panel is used to realize the pressure switch that is automatically adjusted by a button, and the two first through holes are used to place the manual pins of the rupture valve and the supply valve. Thus, the two functions can be integrated through the integrated operation panel, which not only makes the appearance simple, but also effectively reduces the size and has a high degree of integration.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] Please see Figure 1 This embodiment can provide a vacuum generator assembly. The vacuum generator assembly may include: a main valve body 100, a pilot solenoid valve assembly 300, a breaker valve 210, a supply valve 220, a pressure switch assembly 500, a breaker valve manual pin 410, and a supply valve manual pin 420. The breaker valve 210, the supply valve 220, and the pilot solenoid valve assembly 300 are arranged at intervals along a first direction within the main valve body 100.
[0033] The pilot solenoid valve assembly 300 may include a destructive pilot valve 310 and a supply pilot valve 320. The destructive pilot valve 310 controls the opening and closing of the destructive valve 310, and the supply pilot valve 320 controls the opening and closing of the supply valve 320. The pressure switch assembly 500 includes a PCB board 510 and an integrated operation panel 520. The integrated operation panel 520 and the PCB board 510 are fixed to the first side of the main valve body. The integrated operation panel 520 covers one side of the PCB board 510. The PCB board 510 is electrically connected to the pilot solenoid valve assembly 300 to control the on / off state of the pilot solenoid valve assembly 300. The integrated operation panel 520 has a pressure regulating panel 521 and two first through holes 522. The pressure panel 520 is located above the pilot solenoid valve assembly 300. The PCB board 510 has two second through holes 511, and each first through hole 522 corresponds to one second through hole 511. The first side of the main valve body 100 faces the rupture valve 210, the supply valve 220 and the pilot solenoid valve assembly 300. The rupture valve manual pin 410 and the supply valve manual pin 420 are movably fixed on the integrated operation panel 520 through the first through hole 522 and the second through hole 511, so that when the rupture valve manual pin 410 is moved downward by external force, the valve core of the rupture valve 210 is pushed to move horizontally, and when the supply valve manual pin 420 is moved downward by external force, the valve core of the supply valve 220 is pushed to move horizontally.
[0034] In this embodiment, the supply valve 220 supplies compressed air to the vacuum generator 700, and the breaker valve 210 breaks the vacuum state within the suction cup, converting it into atmospheric pressure or positive pressure, thus detaching the workpiece from the suction cup. The supply valve 220 can be installed in a positive pressure pipeline, and the breaker valve 210 can be installed in a vacuum circuit or a circuit where a vacuum exists. The supply valve 220 is used to regulate parameters such as flow rate, pressure, and operating position in the system. When the system needs to increase flow rate or decrease pressure, the supply valve 220 opens, allowing the medium to pass through. Conversely, when the system needs to decrease flow rate or increase pressure, the supply valve 220 closes, preventing the medium from flowing through. The breaker valve 210 is a safety valve that automatically opens when negative pressure or a gradual increase in vacuum occurs due to system operation or shutdown, breaking the vacuum effect and preventing pipes and other components from collapsing or cracking, thus protecting the equipment.
[0035] In this embodiment, the electromagnetic coils of the disruptor pilot valve 310 and the supply pilot valve 320 are energized and thus activated, thereby performing the opening and closing operation of the valve bodies therein. The disruptor pilot valve 310 and the supply pilot valve 320 can move along the first direction of the main valve body ( Figure 1 The left and right arrows are arranged in parallel.
[0036] In this embodiment, the breaker valve 210 and the supply valve 220 can be arranged opposite to each other in the first direction, such that when the breaker valve 210 is open, the supply valve 220 is closed, and when the supply valve 220 is open, the breaker valve 210 is closed. The first direction can be a horizontal direction, i.e. Figure 1 The left and right arrows indicate the direction. The horizontal direction described here is only used to explain the relative positional relationship between the components with reference to the accompanying drawings. If the posture of the vacuum generator assembly changes, the directional indication will also change accordingly. This specification does not limit this aspect.
[0037] In this embodiment, the pilot solenoid valve assembly 300 may include a destructive pilot valve 310 and a supply pilot valve 320. The destructive pilot valve 310 is electrically connected to the destructive valve 210, and the supply pilot valve 320 is electrically connected to the supply valve 220.
[0038] In this embodiment, the pilot solenoid valve assembly 300 is typically connected to the pressure switch assembly 500 so that the pressure switch assembly 500 can control the on / off state of the pilot solenoid valve assembly 300 via an adjustment button, thereby controlling the opening and closing of the breaker valve 210 and the supply valve 220 to regulate the pressure within the vacuum generator assembly. Furthermore, the breaker valve manual pin 410 and the supply valve manual pin 420 are typically corresponding to the breaker valve 210 and the supply valve 220. Therefore, the breaker valve 210, the supply valve 220, and the pilot solenoid valve assembly 300 can be arranged at intervals along a first direction within the main valve body 100. Correspondingly, the pressure switch assembly 500, the breaker valve manual pin 410, and the supply valve manual pin 420 can also be arranged at intervals along the first direction. This allows the pressure switch assembly 500, the breaker valve manual pin 410, and the supply valve manual pin 420 to be positioned in the same direction within the main valve body 100. When manual adjustment is required, the user can see the pressure changes displayed on the pressure switch assembly 500 in real time during the adjustment process, thus enabling more convenient and precise adjustment and avoiding misoperation.
[0039] In this embodiment, the pressure switch that is automatically adjusted by a button can be integrated with the manual pin 410 of the rupture valve and the manual pin 420 of the supply valve. The pressure switch assembly 500 may include a PCB board 510 and an integrated operation panel 520, such as... Figure 2 As shown, the integrated operation panel 520 has a pressure regulating panel 521 and two first through holes 522. The pressure regulating panel 521 is used to realize the pressure switch that is automatically adjusted by the button. The two first through holes 522 are used to place the manual pin 410 of the rupture valve and the manual pin 420 of the supply valve. Thus, the two functions can be integrated through the integrated operation panel 520, which not only makes the appearance simple, but also effectively reduces the size and has a high degree of overall integration.
[0040] In this embodiment, the pressure regulating panel 520 is located above the pilot solenoid valve assembly 300. The pressure regulating panel 520 can be electrically connected to the destructive pilot valve 310 and the supply pilot valve 320 respectively. In some embodiments, it can be electrically connected by a metal spring. Of course, other methods can also be used for connection. The specific method can be determined according to the actual situation. This specification does not limit this embodiment.
[0041] In this embodiment, as Figure 2 As described, the pressure regulating panel 520 may include a pressure regulating button and a pressure display screen. The pressure display screen is used to display the current pressure in real time for monitoring and adjustment. The pressure regulating button can be electrically connected to the PCB board 510 to control the on / off power of the pilot solenoid valve assembly 300. It is understandable that... Figure 2This is merely an example. Those skilled in the art may make other changes to the layout of the voltage regulating panel based on the technical essence of the embodiments in this specification. However, as long as the functions and effects achieved are the same as or similar to those in the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.
[0042] In this embodiment, the integrated operation panel 520 is electrically connected to the PCB board 510. The integrated operation panel 520 is placed on the PCB board 510. In order to make the length of the manual pin 410 of the rupture valve and the manual pin 420 of the supply valve as short as possible, and to facilitate the wiring connection of the PCB board 510 and reduce the overall size, the integrated operation panel 520 and the PCB board 510 can be fixed to the first side of the main valve body 100. The first side is above the rupture valve 210, the supply valve 220 and the pilot solenoid valve assembly 300.
[0043] In this embodiment, the pressure switch assembly can be designed as follows: Figure 2 The integrated structure shown includes an integrated control panel 520 positioned directly above the entire assembly. The control panel 520 has two first through holes 522, and the PCB board 510 has two second through holes 511. Each first through hole 522 and each second through hole 511 correspond vertically in the same direction. A pair of corresponding first through holes 522 and second through holes 511 is used to house either a manual pin 410 for a rupture valve or a manual pin 420 for a supply valve. During installation, one end of the manual pin 410 or the manual pin 420 can be passed sequentially through the first through hole 522 and the second through hole 511, bringing it close to the valve core of the rupture valve or the supply valve, while the other end is movably fixed in the first through hole 522. The manual pin buttons for the supply valve 220 and the rupture valve 210 are embedded in the pressure switch panel for convenient user debugging and data reading.
[0044] In this embodiment, when manual adjustment using the manual pin 410 of the breaker valve is required, one end of the manual pin 410 on the integrated operation panel 520 can be pressed down. When the manual pin 410 is moved downward by external force, the other end will contact the valve core of the breaker valve 210 and push the valve core of the breaker valve 210 to move horizontally, thereby opening the valve core of the breaker valve 210. When the external force is removed, the manual pin 410 of the breaker valve resets, and at this time the valve core of the breaker valve 210 moves horizontally, thereby restoring the valve core of the breaker valve 210 to the closed state. When manual adjustment using the supply valve manual pin 420 is required, one end of the supply valve manual pin 420 on the integrated operation panel 520 can be pressed down. When the supply valve manual pin 420 is moved downward by external force, the other end will contact the valve core of the supply valve 220 and push the valve core of the supply valve 220 to move horizontally, thereby opening the valve core of the destructive valve 210. When the external force is removed, the supply valve manual pin 420 is reset, and at this time the valve core of the supply valve 220 moves horizontally, thereby restoring the valve core of the supply valve 220 to the closed state.
[0045] In this embodiment, as Figure 1 As shown, the rupture valve 210 may include a rupture valve rear cover, a rupture valve 210 valve core, and a rupture valve return spring. The supply valve 220 includes a supply valve rear cover, a supply valve piston, a supply valve 220 valve core, and a supply valve return spring. Of course, the structures of the rupture valve 210 and the supply valve 220 are not limited to the examples described above. Those skilled in the art may make other modifications based on the technical essence of the embodiments in this specification, but as long as the functions and effects achieved are the same as or similar to those in the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.
[0046] From the above description, it can be seen that the embodiments of this specification achieve the following technical effects: The vacuum generator assembly may include a main valve body, a pilot solenoid valve assembly, a breaker valve, a supply valve, a pressure switch assembly, a breaker valve manual pin, and a supply valve manual pin. Since the pilot solenoid valve assembly usually needs to be connected to the pressure switch assembly so that the pressure switch assembly can control the on / off state of the pilot solenoid valve assembly through the adjustment button, and then adjust the pressure inside the vacuum generator assembly by controlling the opening and closing of the breaker valve and the supply valve. Furthermore, the breaker valve manual pin 410 and the supply valve manual pin are usually correspondingly set to the breaker valve and the supply valve. Therefore, the breaker valve, the supply valve, and the pilot solenoid valve assembly can be arranged at intervals along a first direction within the main valve body. Correspondingly, the pressure switch assembly, the breaker valve manual pin, and the supply valve manual pin can also be arranged at intervals along the first direction, so that the pressure switch assembly, the breaker valve manual pin, and the supply valve manual pin can be set in the same direction of the main valve body. When manual adjustment is required, the user can see the pressure changes displayed on the pressure switch assembly in real time during the adjustment process, thus enabling more convenient and accurate adjustment and avoiding misoperation. Furthermore, the pressure switch that is automatically adjusted by a button can be integrated with the manual pins of the rupture valve and the supply valve. The pressure switch assembly can include a PCB board and an integrated operation panel. The integrated operation panel has a pressure regulating panel and two first through holes. The pressure regulating panel is used to realize the pressure switch that is automatically adjusted by a button, and the two first through holes are used to place the manual pins of the rupture valve and the supply valve. Thus, the two functions can be integrated through the integrated operation panel, which not only makes the appearance simple, but also effectively reduces the size and has a high degree of integration.
[0047] In one embodiment, the vacuum generator assembly may further include: an air supply port a, a vacuum port b, and an exhaust port c, wherein the air supply port a and the vacuum port b are disposed on the second side of the main valve body 100 near the rupture valve 210, and the exhaust port c is disposed on the third side opposite to the second side in a first direction.
[0048] In this embodiment, the air supply port a and the vacuum port b are located on the same side, and the exhaust port c is located on the side opposite to the air supply port a and the vacuum port b in the first direction. This allows the air path from the air supply port a to the exhaust port c and from the vacuum port b to the exhaust port c to be straight and short, resulting in low pressure drop and fast response.
[0049] In this embodiment, the gas supply port a and the vacuum port b can be located on the second side of the main valve body. The second side can be the side close to the breaker valve, so that the gas from the gas supply port a can flow through the breaker valve or the supply valve first and then to the exhaust port.
[0050] In one embodiment, the vacuum generator assembly may further include: a vacuum generator 700, which is horizontally arranged and located below the pilot solenoid valve assembly 300. The inlet end of the vacuum generator 700 is located below the supply valve 220, and the outlet end of the vacuum generator 700 is connected to the exhaust port c. A first air passage 001 is formed between the air supply port a and the supply valve 210, a second air passage 002 is formed between the supply valve 220 and the inlet end f of the vacuum generator 700, and a third air passage 003 is formed between the inlet end f of the vacuum generator 700 and the exhaust port c. When the valve core of the supply valve 220 is open, the first air passage 001, the second air passage 002, and the third air passage 003 are connected. A fourth air passage 004 is formed between the vacuum port b and the outlet end g of the vacuum generator 700.
[0051] In this embodiment, the vacuum generator is a pneumatic component that uses the flow of compressed air to create a certain degree of vacuum. To ensure a straight airflow, the vacuum generator 700 can be positioned horizontally. Furthermore, to allow the gas flowing from the supply valve 220 to directly flow into the vacuum generator 700 and reduce the length of the airflow path, such as... Figure 4 As shown, the inlet end f of the vacuum generator 700 can be located below the supply valve 220, so that the gas flowing out from the outlet end e of the supply valve can reach the inlet end f of the vacuum generator 700 by passing through only a vertical section.
[0052] In this embodiment, since the gas flowing out of the vacuum generator 700 needs to be discharged from the vacuum generator assembly, the exhaust port c can be set at the outlet end g of the vacuum generator 700.
[0053] In this embodiment, when the supply valve 220 is closed, the first air passage 001 and the second air passage 002 are isolated, and when the valve core of the supply valve 220 is open, the first air passage 001 and the second air passage 002 are connected.
[0054] In this embodiment, a fourth gas path 004 is formed between the vacuum port b and the vacuum input terminal d of the vacuum generator 700, and between the vacuum input terminal d of the vacuum generator 700 and the outlet terminal g of the vacuum generator 700.
[0055] In this embodiment, the air inlet connector of air supply port a is connected to a positive pressure air source until the pressure switch assembly 500 displays the rated air pressure. Operating state ① (e.g.) Figure 1 (As shown): The pilot valve 320 is not energized, the supply valve 220 is closed, the gas path is blocked, and no pressure is generated at vacuum port b. Operating state ② (as shown) Figure 3As shown): When the pilot valve 320 is energized, the air pressure generated at the piston of the supply valve pushes the valve core of the supply valve 220 to switch, and the valve core of the supply valve 220 opens, connecting the first air path 001, the second air path 002 and the third air path 003. At this time, the air pressure passes through the pipeline of the vacuum generator 700 (i.e. the third air path 003) and generates a negative pressure at point d, which is connected to the vacuum port b. At this time, the vacuum port b also generates a vacuum. The vacuum port b is connected to a suction cup, which can be used to adsorb the workpiece.
[0056] In this embodiment, after the supply valve 320 is opened, the gas pressure flows from e to f. Because the gas path is straight and the stroke is short, the pressure drop is small and the response is fast. Therefore, the above-mentioned gas path structure can achieve high response and quickly reach the required vacuum level.
[0057] In one embodiment, a fifth air passage 005 is formed between the air supply port a and the breaker valve 310, and a sixth air passage 006 is formed between the breaker valve 310 and the vacuum port b. When the valve core of the breaker valve 210 is opened, the fifth air passage 005 and the sixth air passage 006 are connected.
[0058] In one embodiment, the vacuum generator assembly may further include a flow regulating valve 800, which is disposed in the sixth gas path and is used to regulate the flow rate of the sixth gas path.
[0059] In this embodiment, the fifth air passage 005 and the sixth air passage 006 are not connected to the first air passage 001, and in working state ③ (e.g.) Figure 4 (As shown): When negative pressure is not required, the supply valve 320 is closed; the pilot valve 310 is energized, and the left end of the valve core of the pilot valve 210 is subjected to air pressure. The valve core of the pilot valve 210 reverses, and the positive pressure is connected through the air path of the flow regulating valve 800 and the vacuum port. The vacuum port generates positive pressure, at which point the suction cup releases its adsorption on the workpiece. Through reasonable air path design, the pressure drop of the vacuum generator components is small, the response time is fast, and the operating frequency is high during user operation, thereby effectively improving work efficiency.
[0060] In this embodiment, the flow regulating valve 800 can be set in the sixth gas path. In some embodiments, the flow regulating valve 800 can be set on the same side of the gas supply port a and the vacuum port b, and the flow regulating valve 800 can be set between the gas supply port a and the vacuum port b, thereby effectively optimizing the gas path setting, so that the gas path is set with the shortest possible direct connection and the flow rate can be easily adjusted.
[0061] In one embodiment, the vacuum generator assembly may further include: a pressure regulating valve 600, which is fixed at the air supply port a, and is used to regulate the air source pressure at the air supply port a.
[0062] In this embodiment, a pressure regulating valve can be installed on the first gas path 001. A positive pressure gas source is supplied to the gas inlet a. By adjusting the pressure regulating valve, different gas pressures can be set, thereby generating a precise and stable vacuum pressure at the vacuum inlet b. By integrating the pressure regulating valve into the vacuum generator assembly, the inlet pressure can be adjusted, thereby improving the adjustment accuracy of the vacuum degree and stabilizing the pressure at the vacuum inlet.
[0063] In one embodiment, the manual pin 410 of the breaker valve has a first ramp guide surface 415 at the end near the breaker valve 210, and the manual pin 420 of the supply valve has a second ramp guide surface 425 at the end near the supply valve 220.
[0064] In this embodiment, as Figure 5 As described above, the manual pin 410 of the breaker valve may include: a first limiting groove 411, a first baffle 412, and a first return spring 413; the manual pin 420 of the supply valve may include a second limiting groove 421, a second baffle 422, and a second return spring 423.

The first baffle 412 can be fixed in the rear cover 414 of the rupture valve, and the first baffle 412 is at least partially inserted into the first limiting groove 411 to limit the vertical movement range of the manual pin 410 of the rupture valve. The first return spring 413 is sleeved on the side of the manual pin 410 of the rupture valve near the rupture valve 310. When an external force is applied to one end of the manual pin 410 of the rupture valve, causing the manual pin 410 of the rupture valve to move downward, the first return spring 413 is compressed. The other end of the manual pin 410 of the rupture valve contacts the valve core of the rupture valve 210 and pushes the valve core of the rupture valve 210 to move to the right through the first inclined guide surface 415. After moving to the upper end of the first limiting groove 411 of the first baffle 412, the manual pin 410 of the rupture valve is restricted and cannot continue to move downward. At this point, after the external force acting on the manual pin 410 of the breaker valve is removed, the manual pin 410 of the breaker valve moves upward to the reset position under the elastic force of the first reset spring 413.
[0066] In this embodiment, the second limiting groove 421 can be disposed on the side of the supply valve manual pin 420 near the supply valve rear cover 424. The second baffle 422 can be fixed in the supply valve rear cover 424, and the second baffle 422 is at least partially inserted into the second limiting groove 421 to limit the vertical movement range of the supply valve manual pin 420. The second return spring 423 is sleeved on the side of the supply valve manual pin 420 near the supply valve 320. When an external force is applied to one end of the supply valve manual pin 420, causing the supply valve manual pin 420 to move downward, the second return spring 423 is compressed. The other end of the supply valve manual pin 420 contacts the valve core of the supply valve 220 and pushes the valve core of the supply valve 220 to move to the right through the second inclined guide surface 425. After moving to the upper end of the second limiting groove 421 of the second baffle 422, the supply valve manual pin 420 is restricted from moving downward. At this point, after the external force acting on the manual pin 420 of the supply valve is removed, the manual pin 420 of the supply valve moves upward to the reset position under the elastic force of the second reset spring 423.
[0067] In one embodiment, the vacuum generator assembly may further include a silencing assembly 900, which may include a silencing plate 920 and a muffler housing 910, wherein the muffler housing 910 is fixed to the exhaust port c of the vacuum generator assembly, the muffler housing 910 has at least 5 walls, at least 4 of which are provided with perforated grids 911 for exhaust; the silencing plate 920 abuts against the inner wall of the muffler housing 910 and at least covers the perforated grids 911.
[0068] In this embodiment, the noise reduction component 900 can be as follows: Figures 6-7 As shown, since the muffler assembly 900 is embedded in the main valve body 100, the muffler housing 910 can be configured with 5 walls, or of course, 6 walls. The left wall has a clearance hole for the vacuum generator outlet. The specific configuration can be determined according to actual conditions, and this specification does not limit this.
[0069] In this embodiment, the muffler housing 910 may be provided with a perforated grid 911 for discharging the gas flowing out of the vacuum generator outlet. The perforated grid 911 may be provided on at least four walls, and the exhaust efficiency is improved through the four-sided exhaust air passage design.
[0070] In this embodiment, since the upper side of the muffler assembly abuts against the main valve body 100, exhaust cannot be emitted from the upper side of the muffler housing 910. Therefore, perforated grids 911 can be provided on the front, rear, right, and lower walls of the muffler housing 910. The perforated grids 911 can be a grid pattern or, for example, a textured design. Figure 7The striped pattern shown can be specifically determined according to the actual situation, and the embodiments in this specification do not limit it.
[0071] In this embodiment, the muffler 920 can abut against the inner wall of the muffler housing 910 and at least cover the hollowed-out grid 911. The larger the area of the muffler 920, the better the muffler effect. Through the four-sided exhaust air passage design, a high-efficiency muffler effect can be achieved, reducing noise pollution.
[0072] In one embodiment, the sound-absorbing sheet 920 is a one-piece structure, and / or the sound-absorbing sheet 920 is made of high molecular weight polyethylene material.
[0073] In this embodiment, the sound-absorbing sheet 920 can be a one-piece structure or a segmented structure, which can be determined according to the actual situation. This specification does not limit this embodiment.
