Description

Technical Field

[0001] This application relates to the field of gas and liquid mixing, and more particularly to a gas cylinder decanter. Background Technology

[0002] A decanter is a tool that uses gas from a cylinder to add specific gases to wine. By injecting gas into the wine, it increases the surface area of ​​the liquid in contact with air, thereby rapidly oxidizing the wine, softening the tannins, releasing aromas, and enhancing the wine's flavor.

[0003] Existing decanters typically use a replaceable high-pressure gas cylinder as their gas source. During use, the decanter is connected to both the high-pressure cylinder and the container. A needle is attached to the end of the decanter connected to the high-pressure cylinder, and the cylinder's opening is sealed. During cylinder installation, the needle punctures the seal, allowing high-pressure airflow into the decanter. The inventors of this invention discovered that the fixed needle position in existing technologies results in low tolerance for puncturing the seal. For thicker or more flexible seals, the needle can only puncture small openings, leading to unstable or even no airflow. Summary of the Invention

[0009] Optionally, the pressure relief assembly further includes a pressure relief spring, one end of which abuts against the housing, and the other end of which abuts against the pressure relief cover. The pressure relief cover abuts against the pressure relief spring at a position where abutment is formed by a raised abutment edge.

[0010] Optionally, an assembly base is provided inside the housing, the assembly base extends from the gas cylinder connection end toward the container connection end, and the pressure relief cover is sleeved on the assembly base; The pressure relief assembly includes a secondary pressure relief valve. Both the secondary pressure relief valve and the sleeve are disposed within the mounting base. One end of the secondary pressure relief valve is connected to the primary pressure relief valve through the air passage, and the other end of the secondary pressure relief valve is connected to the sleeve through the air passage.

[0011] Optionally, a pin for activating the secondary pressure relief valve is provided in the air passage between the primary pressure relief valve and the secondary pressure relief valve.

[0012] Optionally, the abutment gap between the primary pressure relief valve and the starting device is smaller than the abutment gap between the housing and the pressure relief cover, so that the primary pressure relief valve and the secondary pressure relief valve open sequentially; and / or, Under normal pressure, the primary pressure relief valve is in a closed state, and the secondary pressure relief valve is in a connected state; and / or, Under high pressure, the primary pressure relief valve is in the open state, and the secondary pressure relief valve is in the closed state; and / or, In the connected state, both the primary pressure relief valve and the secondary pressure relief valve are in the connected state.

[0015] The beneficial effects of this application embodiment are as follows: When the gas needle is connected to the high-pressure gas cylinder and the pressure relief component is in a closed state, it will move towards the high-pressure gas cylinder due to pressure, thereby deepening the seal. This allows gas to flow more smoothly from the gas needle, avoiding airflow instability caused by an excessively small or irregular seal, ensuring that gas can enter the liquid container at a stable flow rate, making the mixing of liquid and gas more uniform and the mixing effect more ideal. Regardless of the thickness or material of the seal, the axial movement function of the gas needle allows the gas needle to adjust the size and depth of the seal by moving, thereby ensuring that gas can always flow in stably, enhancing the versatility and reliability of the gas cylinder decanter. The gas in the high-pressure gas cylinder has very high pressure and flow rate when released. When the gas needle punctures the seal, the high-pressure gas flows from the hole in the middle of the gas needle to the tail of the gas needle, generating an instantaneous impact force. This instantaneous impact force can push the gas needle towards the high-pressure gas cylinder in a very short time, producing a strong destructive effect on the seal and further deepening the seal.

[0018] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as "connected to" another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 4 As shown, a gas cylinder decanter 100 includes: a housing 10; a gas cylinder connection end 11 disposed on the housing 10; a container connection end 12 disposed on the housing 10, and connected to the gas cylinder connection end 11 via a gas passage; a pressure relief assembly 20 connected to the gas passage for connecting / closing the gas passage; a sleeve 30 disposed on the gas cylinder connection end 11, the sleeve 30 being connected to the pressure relief assembly 20, a gas needle 40 disposed inside the sleeve 30, the sleeve 30 having space for axial movement of the gas needle 40, and the gas needle 40 being circumferentially airtightly connected to the sleeve 30, so that when the gas needle 40 is connected to the high-pressure gas cylinder 50 and the pressure relief assembly 20 is in a closed state, it tends to move towards the high-pressure gas cylinder 50.

[0021] In this embodiment, the shell 10 is formed by splicing two half-shells 10. However, the composition of the shell 10 is not limited to this. Depending on the specific application scenario, in some embodiments, the shell 10 can be formed by integral molding or by splicing or nesting two or more fragmented shells 10.

[0022] The gas cylinder connection end 11 is disposed on the housing 10. The gas cylinder connection end 11 is provided with a thread for connecting to the high-pressure gas cylinder 50. In use, the high-pressure gas cylinder 50 is assembled with the thread of the gas cylinder connection end 11 by a screw. However, the structure of the gas cylinder connection end 11 is not limited to this. Depending on the specific application scenario, in some embodiments, the gas cylinder connection end 11 is provided with a snap-fit ​​structure to engage with the high-pressure gas cylinder 50, or it is connected to the high-pressure gas cylinder 50 by an interference fit.

[0023] The container connection end 12 connects to the container bottle. A dedicated stopper is located at the bottle neck, with an airflow connection tube and a liquid connection tube. The airflow connection tube connects to the air path, and the liquid connection tube connects to the liquid outlet tube 80 of the decanter 100. When high-pressure airflow enters the container bottle through the air path, it increases the pressure inside the bottle. Under this high pressure, the liquid inside the container flows from the liquid connection tube into the liquid outlet tube 80.

[0024] The container connection end 12 is connected to the bottle stopper by a plug-in connection. However, the connection method between the container connection end 12 and the bottle stopper is not limited to this. Depending on the specific application scenario, in some embodiments, the connection method between the container connection end 12 and the bottle stopper can be (not limited to): screw connection, snap connection or interference fit.

[0025] In this embodiment, the gas path refers to the flow path of gas from the gas needle 40 into the decanter 100 and then into the container bottle. Therefore, the gas path is not a specific pipe, but an airflow channel composed of multiple components. Among them, the gas needle 40 and the pressure relief assembly 20 are both components of the gas path.

[0026] The pressure relief assembly 20 is a switching structure capable of connecting / closing the gas path. The pressure relief assembly 20 includes two pressure relief valves. However, the number of pressure relief valves is not limited to this; depending on the specific application scenario, in some embodiments, the number of pressure relief valves can be one, three, four, or more.

[0027] The pressure relief valve comprising the pressure relief assembly 20 is a mechanical pressure relief valve, which needs to be connected / closed by mechanical pressing, flicking, or plugging. However, the type of pressure relief valve is not limited to this. Depending on the specific application scenario, in some embodiments, the pressure relief valve can be an electronic pressure relief valve. In some embodiments of multi-stage pressure relief valves, the pressure relief valve of the pressure relief assembly 20 can be composed of a combination of mechanical and electronic pressure relief valves.

[0028] In this embodiment, the sleeve 30 is connected to the housing 10. The connection method between the sleeve 30 and the housing 10 is (not limited to): interference fit, screw connection, snap connection, adhesive connection, welding or integral molding.

[0029] The sleeve 30 is hollow inside, and the air needle 40 is disposed inside the sleeve 30, with its needle head 42 extending out of the sleeve 30. The air needle 40 is airtightly connected to the sleeve 30 through a sealing ring. The sealing ring allows relative movement between the air needle 40 and the sleeve 30 while ensuring good airtightness between them. However, the connection method between the air needle 40 and the sleeve 30 is not limited to this. Depending on the specific application scenario, in some embodiments, the air needle 40 and the sleeve 30 are connected by a retractable connecting piece.

[0030] In the above embodiment, when the gas needle 40 is connected to the high-pressure gas cylinder 50 and the pressure relief component 20 is in a closed state, it will move towards the high-pressure gas cylinder 50 due to pressure, thereby deepening the seal. This allows gas to flow more smoothly from the gas needle 40, avoiding airflow instability caused by an excessively small or irregular seal, ensuring that gas can enter the liquid container at a stable flow rate, making the mixing of liquid and gas more uniform and the mixing effect more ideal. Regardless of the thickness or material of the seal, the axial movement function of the gas needle 40 allows it to adjust the size and depth of the seal by moving, thereby ensuring that gas can always flow in stably, enhancing the versatility and reliability of the gas cylinder decanter 100. The gas in the high-pressure gas cylinder 50 has very high pressure and flow rate when released. When the gas needle 40 punctures the seal, the high-pressure gas flows from the hole in the middle of the gas needle 40 to the tail of the gas needle 40, generating an instantaneous impact force. This instantaneous impact force can propel the gas needle 40 toward the high-pressure gas cylinder 50 in a very short time, causing strong damage to the seal and further deepening the breach.

[0031] In some embodiments, the sleeve 30 includes a cylinder portion 31 and a reduced diameter port 32. One end of the cylinder portion 31 is connected to the pressure relief assembly 20, and the other end of the cylinder portion 31 is connected to the reduced diameter port 32. The needle 40 includes a piston portion 41 and a needle head 42. The piston portion 41 is connected to the needle head 42. The piston portion 41 is disposed inside the cylinder portion 31. The needle head 42 is inserted into and passes through the reduced diameter port 32. The cross-sectional area of ​​the piston portion 41 is larger than the cross-sectional area of ​​the needle head 42.

[0032] The cross-sectional area of ​​the piston part 41 and the cross-sectional area of ​​the needle head 42 both refer to their cross-sectional areas in the horizontal direction.

[0033] The sleeve 30 is designed with two parts: a cylinder section 31 and a reduced-bore port 32. The cylinder section 31 provides a stable, airtight space, while the reduced-bore port 32 guides and fixes the needle 40, making its movement more stable and precise. The cross-sectional area of ​​the piston section 41 is larger than that of the needle head 42. The larger piston section 41 can distribute the gas pressure more evenly, ensuring that the needle 40 is subjected to uniform force during movement. This reduces vibration and jitter of the needle 40 during movement and improves the moving accuracy and stability of the needle head 42.

[0034] In some embodiments, the piston portion 41 has a first sealing groove 411 circumferentially formed, and a first sealing ring 412 is disposed in the first sealing groove 411. The inner ring of the first sealing ring 412 is connected to the first sealing groove 411, and the outer ring of the first sealing ring 412 abuts against the inner wall of the cylinder portion 31. The needle head 42 has a second sealing groove 421 circumferentially formed, and a second sealing ring 422 is disposed in the second sealing groove 421. The inner ring of the second sealing ring 422 is connected to the second sealing groove 421, and the outer ring of the second sealing ring 422 abuts against the inner wall of the reduced diameter port 32.

[0035] A first sealing groove 411 is circumferentially formed on the piston part 41, and a first sealing ring 412 is installed in the groove, with its outer ring tightly abutting against the inner wall of the cylinder part 31. This ensures the airtightness between the piston part 41 and the cylinder part 31, preventing gas leakage from the gap between them. A second sealing groove 421 is circumferentially formed on the needle head 42, and a second sealing ring 422 is installed in the groove, with its outer ring tightly abutting against the inner wall of the reduced diameter port 32. This ensures the airtightness between the needle head 42 and the reduced diameter port 32, preventing gas leakage from the gap between them. The second sealing ring 422 not only prevents gas leakage from the gap between the needle head 42 and the reduced diameter port 32, but also effectively prevents high-pressure gas flow from entering the space between the piston part 41 and the sleeve 30 from the peripheral gaps of the needle head 42. Under normal operating conditions, a certain pressure difference needs to be formed on both sides of the piston part 41 to push the gas needle 40 towards the high-pressure gas cylinder 50. The second sealing ring 422 prevents high-pressure airflow from entering the space between the piston part 41 and the sleeve 30, ensuring that the necessary pressure difference can be formed on both sides of the piston part 41, so that the air needle 40 can move smoothly.

[0036] In some embodiments, the end of the piston portion 41 facing the pressure relief assembly 20 is recessed to form a power groove 413.

[0037] The design of the power groove 413 allows the high-pressure gas flowing from the needle 40 to be released directly between the pressure relief assembly 20 and the piston. The recessed design of the power groove 413 increases the space between the needle 40 and the pressure relief assembly 20, avoiding the problem that the outlet of the needle head 42 would be blocked due to the piston being too close to the pressure relief assembly 20, thus preventing the high-pressure gas from being released.

[0038] In some embodiments, the pressure relief assembly 20 includes a pressure relief cover 21 and a primary pressure relief valve 22. The pressure relief cover 21 is movably mounted inside the housing 10, and the primary pressure relief valve 22 is mounted inside the pressure relief cover 21. One end of the primary pressure relief valve 22 is connected to the container connection end 12 through an air passage, and the other end of the primary pressure relief valve 22 is connected to the sleeve 30 through an air passage. The housing 10 is provided with an activation device 60 for opening the primary pressure relief valve 22 at a corresponding position. The activation device 60 abuts against the primary pressure relief valve 22 and opens the primary pressure relief valve 22.

[0039] The pressure relief cover 21 is movably assembled inside the housing 10. The end of the pressure relief cover 21 facing the high-pressure gas cylinder 50 is obstructed by the sleeve 30 and cannot be separated from the housing 10. When an external force is applied to the housing 10, causing the housing 10 to move towards the high-pressure gas cylinder 50, the distance between the housing 10 and the pressure relief cover 21 will gradually shorten until the activation device 60 of the housing 10 corresponding to the first-stage pressure relief valve 22 contacts the first-stage pressure relief valve 22 and presses the first-stage pressure relief valve 22, causing the first-stage pressure relief valve 22 to open. At this time, the gas path is connected, and the airflow flows from the high-pressure gas cylinder 50 to the container bottle.

[0040] The pressure relief hood 21 is movably connected to the housing 10, and the starting device 60 is mounted on the housing 10. When the housing 10 moves towards the high-pressure gas cylinder 50, the starting device 60 abuts against the first-stage pressure relief valve 22 and opens the valve. This physical opening method allows the user to precisely control the timing of the high-pressure gas flow into the container by manually operating the position of the housing 10. This makes the mixing process more flexible, allowing the user to adjust the mixing time and intensity according to the type and quality of the liquid, as well as personal taste preferences. The physical opening method reduces the use of electronic components, lowering the equipment unreliability caused by electronic malfunctions. This makes the equipment more stable during operation, reducing the risk of uncontrollable gas flow due to electronic malfunctions.

[0041] In some embodiments, the pressure relief assembly 20 further includes a pressure relief spring 23, one end of which abuts against the housing 10 and the other end of which abuts against the pressure relief cover 21. The pressure relief cover 21 abuts against the pressure relief spring 23 at the position where it abuts against the pressure relief spring 23, forming an abutment flange 211.

[0042] The pressure relief cover 21 is airtightly connected to the housing 10, or the sleeve 30 is connected to the first-stage pressure relief valve 22 via a pipeline.

[0043] One end of the pressure relief spring 23 abuts against the housing 10, and the other end abuts against the pressure relief cover 21. When the housing 10 moves toward the pressure relief cover 21, the pressure relief spring 23 provides a certain resistance, which allows the user to clearly feel the damping sensation during operation. This improves the intuitiveness of operation and enhances the user experience. The damping sensation allows the user to more precisely control the movement of the housing 10, thereby more precisely controlling the entry time of the high-pressure airflow. Precise control is crucial for optimizing the mixing effect, and the user can flexibly adjust the mixing time and intensity as needed. The reset function of the pressure relief spring 23 allows the relative position of the pressure relief cover 21 and the housing 10 to automatically return to the initial position after operation, improving the ease of use of the equipment.

[0044] In some embodiments, a mounting base 70 is provided inside the housing 10, extending from the gas cylinder connection end 11 toward the container connection end 12, and a pressure relief cover 21 is fitted onto the mounting base 70; the pressure relief assembly 20 includes a secondary pressure relief valve 24, and both the secondary pressure relief valve 24 and the sleeve 30 are disposed inside the mounting base 70. One end of the secondary pressure relief valve 24 is connected to the primary pressure relief valve 22 through an air passage, and the other end of the secondary pressure relief valve 24 is connected to the sleeve 30 through an air passage.

[0045] The secondary pressure relief valve 24 is airtightly connected to the inner wall of the mounting base 70. The end of the secondary pressure relief valve 24 facing the sleeve 30 can either abut against or separate from the sleeve 30. Because the outer circumference of the sleeve 30 is airtightly connected to the inner wall of the mounting base 70, and the secondary pressure relief valve 24 is also airtightly connected to the inner wall of the mounting base 70, a closed air passage is formed between the sleeve 30 and the secondary pressure relief valve 24. Regardless of whether the sleeve 30 and the secondary pressure relief valve 24 are connected, high-pressure airflow will not leak out.

[0046] The mounting base 70 extends from the gas cylinder connection end 11 towards the container connection end 12, and the pressure relief cover 21 is fitted onto the mounting base 70. This allows the mounting base 70 to precisely guide the movement of the pressure relief cover 21, ensuring smoother and more accurate movement of the pressure relief cover 21 within the housing 10. It also ensures that the pressure relief cover 21 accurately contacts the starting device 60 during operation, thereby reliably opening the first-stage pressure relief valve 22. The two-stage pressure relief protection mechanism formed by the two pressure relief valves reduces the safety hazard caused by uncontrolled flow of air from the high-pressure gas cylinder 50 to the container bottle due to accidental failure of the pressure relief cover 21.

[0047] In some embodiments, a pin 25 for activating the secondary pressure relief valve 24 is provided in the air passage between the primary pressure relief valve 22 and the secondary pressure relief valve 24. The pin 25 is movably mounted in the air passage. During the process of the pressure relief cover 21 moving toward the gas cylinder connection end 11, the pin 25 abuts against the primary pressure relief valve 22 and the secondary pressure relief valve 24 respectively and opens the secondary pressure relief valve 24.

[0048] The power for the pressure relief cover 21 to move toward the gas cylinder connection end 11 comes from: an external force applied to the housing 10 or the high-pressure gas cylinder 50, causing the housing 10 to move the pressure relief cover 21; and the pressure relief cover 21 moving toward the high-pressure gas cylinder 50 under the action of the pressure relief spring 23.

[0049] One end of the pressure relief spring 23 is connected to the abutment flange 211, and the other end is connected to the housing 10 adjacent to the primary pressure relief valve 22. Under the action of the spring force of the pressure relief spring 23, the pressure relief cover 21 drives the primary pressure relief valve 22 to move towards the secondary pressure relief valve 24, so that the ejector pin 25 abuts against the secondary pressure relief valve 24. Therefore, under normal pressure, the secondary pressure relief valve 24 is in the open state, and the primary pressure relief valve 22 is in the closed state.

[0050] Under the action of high-pressure gas and pressure relief spring 23, pressure relief cover 21 reciprocates along mounting base 70, and drives primary pressure relief valve 22 and secondary pressure relief valve 24 to sequentially connect the gas path, so that high-pressure gas is periodically transmitted to container connection end 12.

[0051] When the high-pressure gas cylinder 50 is punctured, the high-pressure gas flow passes through the secondary pressure relief valve 24 and enters the space between the primary and secondary pressure relief valves 22 and 24. At this time, the high-pressure gas flow exerts a force on the pressure relief cover 21, causing it to move towards the activation device 60 until the primary pressure relief valve 22 is opened. The secondary pressure relief valve 24 closes due to the disappearance of pressure from the pressure pin 25 and the action of the high-pressure gas flow. Thus, the gas cylinder decanter 100 completes one wave of high-pressure gas delivery. After the high-pressure gas flow in the primary pressure relief valve 22 is discharged, the pressure relief cover 21 returns to its original position under the action of the pressure relief spring 23. The primary pressure relief valve 22 disengages from the activation device 60 and closes. The secondary pressure relief valve 24 opens under the action of the pressure pin 25 against the primary pressure relief valve 22, completing a new wave of recharging. Then, under the action of the high-pressure gas, the pressure relief cover 21 moves towards the activation device 60, and the primary pressure relief valve 22 opens to release pressure. Under the action of the high-pressure gas cylinder 50 and the pressure relief spring 23, the gas cylinder decanter 100 can autonomously and periodically deliver high-pressure gas into the container. Under the combined action of the high-pressure gas cylinder 50 and the pressure relief spring 23, the pressure relief cover 21 reciprocates along the mounting base 70, causing the primary pressure relief valve 22 and the secondary pressure relief valve 24 to sequentially connect the gas path. This allows the high-pressure gas to be autonomously and periodically transmitted to the container connection end 12 without continuous external operation, improving the automation level of the equipment.

[0052] In some implementations, when the user needs to directly connect the high-pressure gas cylinder 50 to the container bottle, they can press the housing 10 or the high-pressure gas cylinder 50 to make the starting device 60 abut against the first-stage pressure relief valve 22, thus opening the first-stage pressure relief valve 22. Then, the housing 10 continues to move, compressing the pressure relief spring 23 and abutting against the pressure relief cover 21, causing the pressure relief cover 21 to move towards the sleeve 30, so that the first-stage pressure relief cover 21 abuts against the ejector pin 25 and then against the second pressure relief cover 21. At this time, the second pressure relief cover 21 also opens, and the high-pressure gas cylinder 50 is directly connected to the container bottle. When the user needs to directly connect the high-pressure gas cylinder 50 to the container bottle, they can press the housing 10 or the high-pressure gas cylinder 50 to make both the first-stage pressure relief valve 22 and the second-stage pressure relief valve 24 be in the connected state, thus achieving direct connection between the high-pressure gas cylinder 50 and the container bottle. This provides users with more flexible operating options and meets the usage needs in different scenarios.

[0053] In some embodiments, the pressure relief spring 23 is also arranged in another way, with the pressure relief spring 23 positioned between the abutment flange 211 and the housing 10 adjacent to the secondary pressure relief valve 24. Normally, the pressure relief cover 21 is in contact with the housing 10 where the activation device 60 is located. After pressing the housing 10, the activation device 60 first abuts against the primary pressure relief valve 22 and opens it. Then, the housing 10 continues to move the pressure relief cover 21, causing the end of the primary pressure relief valve 22 to abut against the ejector pin 25, and the ejector pin 25 to abut against the secondary pressure relief valve 24, thus activating the secondary pressure relief valve 24. In this embodiment, both the primary pressure relief valve 22 and the secondary pressure relief valve 24 require external force to be applied by the user to the housing 10 or the high-pressure gas cylinder 50.

[0054] In some embodiments, the abutment gap between the primary pressure relief valve 22 and the starting device 60 is smaller than the abutment gap between the housing 10 and the pressure relief cover 21, so that the primary pressure relief valve 22 and the secondary pressure relief valve 24 are opened sequentially.

[0055] The contact gap between the primary pressure relief valve 22 and the starting device 60 is smaller than the contact gap between the housing 10 and the pressure relief cover 21, ensuring that the primary pressure relief valve 22 opens before the secondary pressure relief valve 24. When manually pressing to connect the air passage, the pressure relief cover 21 moves towards the secondary pressure relief valve 24, compressing the air between the pressure relief cover 21 and the secondary pressure relief valve 24, thus generating resistance. By allowing the primary pressure relief valve 22 to open first, connecting to the external environment, no compressed air is generated between the pressure relief cover 21 and the secondary pressure relief valve 24, thereby reducing the resistance during manual pressure relief and improving the comfort and convenience of operation.

[0056] In some embodiments, the first-stage pressure relief valve 22 includes: a first pressure relief plug 221, a first airtight core 222, and a first return spring 223. A pressure relief nozzle 212 is provided on the pressure relief cover 21. One end of the first airtight core 222 is inserted into and protrudes from the pressure relief nozzle 212. The first pressure relief plug 221 is disposed inside the pressure relief cover 21 and connected to the pressure relief cover 21. The first return spring 223 is disposed between the first airtight core 222 and the first pressure relief plug 221. One end of the first return spring 223 abuts against the first airtight core 222, and the other end of the first return spring 223 abuts against the first pressure relief plug 221.

[0057] After the starting device 60 comes into contact with one end of the first airtight core 222 that extends out of the pressure relief nozzle 212, it pushes the first airtight core 222 toward the first pressure relief plug 221, simultaneously compressing the first return spring 223, and the first-stage pressure relief valve 22 is in the connected state. After the starting device 60 disengages from the first airtight core 222, the first return spring 223 pushes the first pressure relief plug 221 toward the pressure relief nozzle 212 and blocks the pressure relief nozzle 212, and the first-stage pressure relief valve 22 is in the closed state.

[0058] One end of the first airtight core 222 is inserted into and protrudes from the pressure relief nozzle 212, ensuring the airtightness of the air passage. The first reset spring 223 is located between the first airtight core 222 and the first pressure relief plug 221, ensuring that the first-stage pressure relief valve 22 can automatically reset after each operation.

[0059] In some embodiments, the secondary pressure relief valve 24 includes: a second pressure relief housing 241, a second pressure relief plug 242, a second airtight core 243, and a second return spring 244. The second pressure relief housing 241 is disposed in the mounting base 70 and has a pressure relief port 2411. The second airtight core 243 is disposed in the pressure relief housing 10, with one end of the second airtight core 243 inserted into the pressure relief port 2411. The second pressure relief plug 242 is connected to the end of the second pressure relief housing 241 facing away from the second airtight core 243. The second return spring 244 is disposed between the second pressure relief plug 242 and the second airtight core 243, with one end of the second return spring 244 abutting against the second airtight core 243 and the other end of the second return spring 244 abutting against the second pressure relief plug 242.

[0060] After the ejector pin 25 abuts against one end of the second airtight core 243, it pushes the second airtight core 243 toward the second pressure relief plug 242, simultaneously compressing the second return spring 244, and the secondary pressure relief valve 24 is in the connected state. After the ejector pin 25 disengages from the second airtight core 243, the second return spring 244 pushes the second pressure relief plug 242 toward the pressure relief port 2411 and blocks the pressure relief port 2411, and the secondary pressure relief valve 24 is in the closed state.

[0061] One end of the second airtight core 243 is inserted into the pressure relief port 2411 to ensure the airtightness of the air circuit. The second reset spring 244 is located between the second airtight core 243 and the second pressure relief plug 242 to ensure that the secondary pressure relief valve 24 can automatically reset after each operation.

[0062] In some embodiments, the ejector pin 25 is disposed between the first pressure relief plug 221 and the second airtight core 243. After the first pressure relief plug 221 comes into contact with the ejector pin 25, it impacts the second airtight core 243, thereby establishing a connection between the two airtight components.
