Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a common household appliance that keeps food or other items at a constant low temperature. A refrigerator consists of a cabinet and drawers inside the cabinet. The drawers create a negative pressure environment to preserve food.

[0003] A drawer may include a drawer body and a handle. The handle is movably located on the front side of the drawer body, so that the drawer body can be moved relative to the cabinet by the handle, and the pressure relief valve can be closed or opened by the handle to realize the pressure relief process of the drawer body's containing space.

[0004] However, when the drawer is in the pushed-in position, the storage space is easily connected to the outside of the drawer, resulting in poor sealing and affecting the drawer's food preservation effect. Utility Model Content

[0005] This application provides a refrigerator that solves the technical problem of poor drawer sealing, which affects the drawer's food preservation effect.

[0006] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0007] The enclosure is equipped with a liner;

[0008] An air extraction device is provided in the housing; the air extraction device is provided with a control component, which is provided in the inner liner of the housing, and the control component controls the opening and closing of the air extraction device;

[0009] Drawer, the drawer comprising:

[0010] The drawer body is movably mounted within the box liner; the drawer body has a receiving space, and the receiving space is connected to the air extraction port of the air extraction device.

[0011] A connecting bracket is rotatably mounted on the drawer body, and the connecting bracket is provided with a contact element;

[0012] A handle is located on the front side of the drawer body; the handle is connected to the connecting bracket to drive the connecting bracket to rotate relative to the drawer body.

[0013] When the drawer is in the pushed-in state and the handle is in the first position, the contact member abuts against the control member; when the drawer is in the pulled-out state, the contact member disengages from the control member.

[0014] The design of the contact and control components avoids poor sealing caused by the drawer not being pushed in properly or the pressure relief valve not being closed. The control component can be triggered by the contact component to control the operation of the air extraction device, ensuring automatic air extraction when the drawer is pushed in, simplifying user operation. When the air extraction device is not running, the refrigerator or control component can issue a prompt to remind the user to check the status of the drawer, further ensuring the drawer's sealing and preservation effects. The design of the handle and connecting bracket makes it easy for users to operate when pushing in or pulling out the drawer, improving the user experience.

[0015] In some embodiments of this application, the contact end of the control element faces downward;

[0016] When the drawer is in the pushed-in state and the handle is in the first position, the line connecting the contact element and the rotating shaft of the connecting frame is parallel to the horizontal direction.

[0017] The downward-facing contact end of the control component ensures accurate contact with the control component when the drawer is pushed into place. This reliably controls the opening of the air extraction device, creating a negative pressure environment in the drawer and improving its sealing performance. Users only need to push the drawer into place and position the handle in the first position to ensure a secure seal, simplifying the operation and enhancing the user experience.

[0018] In some embodiments of this application, the control element is disposed on the side of the box liner; the control element is provided with:

[0019] The movable part is movable relative to the control member in a vertical direction, with a first end of the movable part facing the contact end of the control member and a second end of the movable part facing downward.

[0020] By placing the control component on the side of the drawer liner and designing the movable part to move vertically, it is ensured that when the drawer body is pushed into place, the first end of the movable part can accurately contact the contact end of the control component. This ensures that the drawer body can reliably control the opening of the air extraction device when pushed into place, thereby creating a negative pressure state in the storage space and improving the drawer's sealing effect. The vertical movement of the movable part allows the control component to adapt more flexibly to the pushing and pulling actions of the drawer body, avoiding accidental activation of the control component and increasing the reliability of the system.

[0021] In some embodiments of this application, the control element is provided with a guide port;

[0022] The movable part is inserted into the guide opening, with at least a portion of the movable part located inside the control member and at least a portion of the movable part located outside the control member.

[0023] By incorporating a guide opening, the movable part can move freely within it, ensuring that when the drawer body is pushed into place, the first end of the movable part accurately contacts the contact end of the control component. This ensures that the air extraction device can reliably activate when the drawer body is pushed into place, creating a negative pressure state in the storage space and improving the drawer's sealing effect. The guide opening design ensures the vertical movement trajectory of the movable part, preventing it from failing to contact the control component. The design of the movable part passing through the guide opening allows the control component to more flexibly adapt to the drawer's pushing and pulling actions, increasing the system's reliability. The design of the movable part being located inside and outside the control component ensures stable movement of the movable part within the guide opening, improving the system's reliability and durability.

[0024] In some embodiments of this application, the box liner is provided with:

[0025] Guide member, the guide member being connected to the movable part;

[0026] A limiting member is provided at a distance from the guide member, and the limiting member is used to prevent the movable part from disengaging from the guide member.

[0027] By incorporating guides and limiters, the moving part maintains the correct trajectory throughout the drawer's insertion and removal. This design ensures that when the drawer is fully inserted, the moving part accurately contacts the control mechanism, reliably controlling the activation of the suction device and maintaining negative pressure in the drawer's storage space, thus improving its sealing performance. The limiters effectively prevent the moving part from detaching from the guides during movement, ensuring it always moves along the correct path and preventing poor drawer sealing due to the moving part detaching from the guides and failing to trigger the control mechanism. The combined design of the guides and limiters effectively guides and restricts the moving part during movement, increasing system reliability and durability.

[0028] In some embodiments of this application, the control element is provided with an elastic portion;

[0029] The elastic part is connected to the movable part, and the elastic part is at least used to drive the movable part to move downward relative to the control member.

[0030] By incorporating an elastic element, the movable part can accurately contact the control element when the drawer is pushed into place, ensuring that the drawer body can reliably control the opening of the air extraction device when pushed into place, thereby maintaining a negative pressure state in the storage space and improving the drawer's sealing effect. The design of the elastic element allows the movable part to automatically adjust its position, ensuring that it always contacts the control element when the drawer is pushed into place. The design of the elastic element ensures that the movable part is always subjected to effective elastic force during movement, increasing the reliability of the system.

[0031] In some embodiments of this application, the inner box is provided with an opening;

[0032] When the drawer is in the pushed-in state, at least a portion of the connecting bracket passes through the movable opening;

[0033] When the drawer is in the pulled-out state, the connecting bracket is located outside the movable opening.

[0034] By incorporating a movable opening, the connecting bracket can be inserted into the opening when the drawer is pushed in, ensuring that the connecting bracket accurately contacts the control component when the drawer is fully inserted. This reliably controls the activation of the suction device, maintaining a negative pressure state in the storage space and improving the drawer's sealing effect. The movable opening design ensures that the connecting bracket maintains the correct movement trajectory during the drawer's insertion and removal, preventing poor sealing caused by incomplete drawer insertion or incorrect connecting bracket positioning. The movable opening design also effectively guides the connecting bracket during movement, increasing system reliability and ensuring stable movement of the connecting bracket within the movable opening, thus improving the system's reliability and durability.

[0035] In some embodiments of this application, a shielding member is provided on the side of the box liner, and the shielding member is at least used to shield the control member.

[0036] The shield is used to protect the control components from external environmental influences. It covers the components, preventing dust, moisture, and other external factors from affecting them, thus ensuring normal operation and reliably controlling the opening of the suction device. This maintains negative pressure in the drawer space, improving the drawer's sealing performance. The shield's design effectively protects the control components, extending their lifespan and improving system reliability. Furthermore, the shield prevents accidental contact with the control components while operating the drawer, ensuring they remain in the correct working state during drawer insertion and removal, preventing poor sealing due to misoperation.

[0037] In some embodiments of this application, the distance between the contact element and the rotating shaft of the connecting frame is less than the distance between the handle and the rotating shaft of the connecting frame.

[0038] Because of the shorter distance between the contact element and the rotating shaft of the connecting bracket, the contact element can engage with the control element more quickly and accurately when the handle is operated. This design ensures that the contact element reliably controls the opening of the suction device when the drawer body is pushed into place, maintaining a negative pressure state in the storage space and improving the drawer's sealing effect. The longer distance between the handle and the rotating shaft of the connecting bracket allows the user to apply greater torque when operating the handle, making it easier to push or pull the drawer. This design improves operational sensitivity and convenience.

[0039] Secondly, embodiments of this application provide a refrigerator, comprising:

[0040] The enclosure is equipped with a liner;

[0041] An air extraction device is provided in the housing; the air extraction device is provided with a control component, which is provided in the inner liner of the housing, and the control component controls the opening and closing of the air extraction device;

[0042] Drawer, the drawer comprising:

[0043] The drawer body is movably mounted within the box liner; the drawer body has a receiving space, and the receiving space is connected to the air extraction port of the air extraction device.

[0044] The drawer body is provided with a pressure relief port, which is connected to the accommodating space;

[0045] A connecting bracket is rotatably mounted on the drawer body, and the connecting bracket is provided with a contact element;

[0046] A handle is located on the front side of the drawer body; the handle is connected to the connecting bracket to drive the connecting bracket to rotate relative to the drawer body.

[0047] A pressure relief valve is provided on the handle lever;

[0048] When the drawer is in the pushed-in state and the handle is in the first position, the pressure relief valve closes the pressure relief port; the contact element abuts against the control element, and the control element controls the air extraction device to open.

[0049] When the drawer is in the pushed-in state and the handle is in the second position, the pressure relief valve opens the pressure relief port; the contact element and the control element are not in contact, and the control element controls the air extraction device to close.

[0069] As mentioned in the background technology, in related technologies, slight differences in the travel distance of refrigerator drawers may not be perceived by users, resulting in the refrigerator drawer not being pushed into place. This makes it easy for the storage space to connect with the outside of the drawer, resulting in poor sealing of the drawer and affecting the preservation effect of the drawer.

[0070] In view of this, the refrigerator in this embodiment avoids the problem of poor sealing effect caused by the drawer body not being pushed in properly or the pressure relief valve not being closed by setting up contact components and control components. The control components can be triggered by contact components to control the operation of the air extraction device, ensuring automatic air extraction when the drawer is pushed in properly, simplifying user operation. When the air extraction device is not running, the refrigerator or control components can issue a prompt to remind the user to check the status of the drawer, further ensuring the sealing and preservation effect of the drawer. The design of the handle and connecting bracket makes it convenient for users to operate when pushing in or pulling out the drawer body, improving the user experience.

[0077] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0078] Reference Figure 1-Figure 5 This application provides a refrigerator, including:

[0079] The enclosure can be equipped with a 100mm inner liner.

[0080] It also includes an air extraction device 200, which is installed in the housing.

[0081] The air extraction device 200 may be equipped with a control element 300, which may be located in the inner chamber 100. The control element 300 controls the opening and closing of the air extraction device 200.

[0082] It may also include a drawer 400, which may include a drawer body 410, movably mounted on the inner box 100.

[0083] The drawer body 410 may be provided with a receiving space, which may be connected to the air extraction port of the air extraction device 200.

[0084] The drawer also includes a connecting bracket 420, which is rotatably mounted on the drawer body 410, and the connecting bracket 420 may be provided with a contact element 421;

[0085] The drawer also includes a handle 430, which can be located on the front side of the drawer body 410; the handle 430 is connected to a connecting bracket 420 to drive the connecting bracket 420 to rotate relative to the drawer body 410.

[0086] When the drawer 400 is in the pushed-in state and the handle 430 is in the first position, the contact 421 can abut against the control 300; when the drawer 400 is in the pulled-out state, the contact 421 can disengage from the control 300.

[0087] During use, when the drawer 400 is pushed in and the handle 430 is in the first position, the contact 421 abuts against the control 300, thereby controlling the opening of the vacuum device 200, so that the containing space is in a negative pressure state, ensuring the sealing effect of the drawer.

[0088] When the contact 421 is separated from the control 300 for a certain period of time, the control 300 can be set to emit an alarm sound to remind the user that the drawer body 410 has been left open for an extended period, preventing the drawer body 410 from being in a non-vacuum state for a prolonged period, which could affect the safety function. The control 300 can be set to emit an alarm sound by electrically connecting it to the refrigerator's control system. The refrigerator's control system can be equipped with a timing module. When the control 300 remains closed for more than a set time, such as 30 seconds, the control system controls the alarm to sound. The alarm can be a buzzer. It should be understood that as long as the control 300 remains closed for more than the set time, it can generate an alarm to remind the user. This application embodiment does not impose excessive restrictions on the implementation method.

[0089] In the first position of the handle 430, the drawer body 410 is fully pushed into the box liner 100, and the drawer body 100 and the box liner 100 can form a sealed storage space.

[0090] The design of the contact element 421 and the control element 300 avoids the problem of poor sealing caused by the drawer body 410 not being pushed in properly or the pressure relief valve not being closed. The control element 300 can be triggered by the contact element 421 to control the operation of the vacuum device 200, ensuring automatic vacuuming when the drawer is pushed in properly, simplifying user operation. When the vacuum device 200 is not running, the refrigerator or the control element 300 can issue a prompt to remind the user to check the status of the drawer 400, further ensuring the sealing and preservation effect of the drawer 400. The design of the handle 430 and the connecting bracket 420 makes it convenient for users to operate when pushing in or pulling out the drawer body 410, improving the user experience.

[0091] In some possible implementations, the contact end of the control element 300 may face downwards.

[0092] When the drawer 400 is in the pushed-in state and the handle 430 is in the first position, the contact 421 can be arranged parallel to the horizontal direction along the line connecting the rotating shaft of the connecting bracket 420.

[0093] The downward-facing contact end of the control element 300 ensures that the contact element 421 accurately contacts the control element 300 when the drawer body 410 is pushed into place. This guarantees that the drawer body 410 can reliably control the opening of the vacuum device 200 when pushed into place, thereby creating a negative pressure state in the storage space and improving the sealing effect of the drawer 400. Users only need to push the drawer body 410 into place and place the handle 430 in the first position to ensure the sealing effect of the drawer 400, simplifying the user's operation steps and improving the user experience.

[0094] refer to Figures 4-5 In some possible implementations, the control element 300 is disposed on the side of the box liner 100.

[0095] The control component 300 may be provided with a movable part 310, which can move vertically relative to the control component 300. The first end of the movable part 310 may face the contact end of the control component 300, and the second end of the movable part 310 may face downward.

[0096] The first end of the movable part 310 faces the contact end of the control member 300, which means that the first end of the movable part 310 will contact the contact end of the control member 300 when the drawer body 410 is pushed into place and the handle 430 is in the first position.

[0097] By placing the control element 300 on the side of the drawer liner 100 and designing the movable part 310 to move vertically, it is ensured that when the drawer body 410 is pushed into place, the first end of the movable part 310 can accurately contact the contact end of the control element 300. This ensures that the drawer body 410 can reliably control the opening of the vacuum device 200 when pushed into place, thereby keeping the accommodating space under negative pressure and improving the sealing effect of the drawer 400. The vertical movement of the movable part 310 allows the control element 300 to more flexibly adapt to the pushing and pulling actions of the drawer body 410, avoiding accidental activation of the control element 300 and increasing the reliability of the system.

[0098] refer to Figure 6-Figure 8 In some possible implementations, the control element 300 is provided with a guide port 320.

[0099] The movable part 310 can be inserted into the guide opening 320. At least a portion of the movable part 310 can be located inside the control member 300, and at least a portion of the movable part can be located outside the control member 300.

[0100] The guide opening 320 is an opening or channel for guiding the movement of the movable part 310; the movable part 310 can be disposed within the guide opening 320, meaning that a part of the movable part 310 can move through the guide opening 320; at least a portion of the movable part 310 is located inside the control member 300, that is, a part of the movable part 310 is inside the control member 300; at least a portion of the movable part 310 is located outside the control member 300, that is, another part of the movable part 310 is outside the control member 300.

[0101] By providing a guide opening 320, the movable part 310 can move freely within the guide opening 320, ensuring that when the drawer body 410 is pushed into place, the first end of the movable part 310 can accurately contact the contact end of the control component 300. This ensures that the drawer body 410 can reliably open the vacuum device 200 when pushed into place, thereby creating a negative pressure state in the accommodating space and improving the drawer's sealing effect. The design of the guide opening 320 ensures the vertical movement trajectory of the movable part 310, preventing the movable part 310 from failing to contact the control component 300. The design of the movable part 310 passing through the guide opening 320 allows the control component 300 to more flexibly adapt to the drawer's pushing and pulling actions, increasing the system's reliability. The design of the movable part 310 being located on the inner and outer sides of the control component 300 ensures the stable movement of the movable part 310 within the guide opening 320, improving the system's reliability and durability.

[0102] It's important to understand that the control element 300 can be a micro switch. A micro switch is a mechanical switch characterized by its small size and rapid action. It is typically used in applications requiring high precision and reliability. The working principle of a micro switch is based on a combination of lever and spring. When an external force is applied to the lever, the internal spring moves rapidly, causing a change in the switch contacts, thereby opening or closing the circuit. By using the control element 300, which is a micro switch, after the drawer body 410 is pushed into place, when the contact element 421 pushes the movable part 310 upward, the movable part 310 triggers the control element 300, causing the trigger element 300 to respond quickly and activate the vacuum device 200, instantly creating a vacuum in the accommodating space.

[0103] In some possible implementations, the movable part 310 is a long strip structure, which can be a cylinder or a cuboid. The two ends of the movable part 310 that contact the contact member 420 and the trigger member 300 have contact heads with larger cross-sectional areas. By setting contact heads, the contact area between the movable part 310 and the contact member 420 and the trigger member 300 is increased, so that the trigger member 300 can be stably triggered and activated.

[0104] refer to Figures 4-5 In some possible implementations, the control element 300 may be provided with an elastic portion 330.

[0105] The elastic part 330 can be connected to the movable part 310, and the elastic part 330 is at least used to drive the movable part 310 to move downward relative to the control member 300.

[0106] During use, when the user pulls the handle 430 to open the drawer body 410, the contact 420 moves downwards, and the elastic element 330 extends, causing the movable part 310 to naturally move away from the trigger part 300 to avoid accidental activation. At this time, when the drawer body 410 is in the open state, the pressure relief valve is open, the vacuum device 200 is not working, and the storage space inside the drawer body 410 is not vacuumed. When the user pushes the drawer body 410 into the liner 100, the handle 430 is in the first position, the contact 420 moves upwards, lifting the movable part 310, causing the movable part 310 to approach and press against the trigger part 300. At this time, the elastic element 330 is compressed, the pressure relief valve is closed, the vacuum device 200 is working, and the storage space inside the drawer body 410 gradually becomes vacuumed.

[0107] By incorporating the elastic part 330, the movable part 310 can accurately contact the contact end of the control component 300 when the drawer is pushed into place. This ensures that the drawer body 410 can reliably control the opening of the vacuum device 200 when pushed into place, thereby maintaining a negative pressure state in the accommodating space and improving the sealing effect of the drawer 400. The design of the elastic part 330 allows the movable part 310 to automatically adjust its position, ensuring that it is always in contact with the contact end of the control component 300 when the drawer is pushed into place. The design of the elastic part 330 ensures that the movable part 310 is always subjected to effective elastic force during movement, increasing the reliability of the system.

[0108] refer to Figures 7-9 In some possible implementations, the inner box 100 may be provided with a guide 110, which may be connected to the movable part 310.

[0109] The box liner 100 may also be provided with a limiting member 120, which may be provided at intervals with the guide member 110. The limiting member 120 is used to restrict the moving part 310 from disengaging from the guide member 110.

[0110] The guide 110 is used to guide the movement of the movable part 310, ensuring that the movable part 310 maintains the correct movement trajectory during the pushing and pulling of the drawer body 410; the guide 110 can be connected to the movable part 310, which means that the movable part 310 is always guided by the guide 110 during movement; the limiting member 120 is used to limit the relative position of the movable part 310 and the guide 110, preventing the movable part 310 from disengaging from the guide 110; the limiting member 120 and the guide 110 are spaced apart, which means that the limiting member 120 and the guide 110 are a certain distance apart within the drawer liner 100, so as to provide effective restriction and guidance during the movement of the movable part 310.

[0111] By incorporating guide 110 and limit 120, the moving part 310 maintains the correct trajectory during the pushing and pulling of the drawer body 410. This design ensures that when the drawer body 4110 is pushed into place, the moving part 310 accurately contacts the contact end of the control element 300, thereby reliably controlling the opening of the vacuum device 200, maintaining a negative pressure state in the accommodating space, and improving the drawer's sealing effect. The limit 120 effectively prevents the moving part 310 from detaching from the guide 110 during movement, ensuring that the moving part 310 always moves on the correct track, preventing poor drawer sealing caused by the moving part 310 detaching from the guide 110 and failing to trigger the control element 300. The combined design of guide 110 and limit 120 ensures that the moving part 310 is effectively guided and restricted during movement, increasing system reliability and improving system durability.

[0112] In some possible implementations, the inner liner 100 is provided with an opening 130.

[0113] When the drawer 400 is in the pushed-in position, at least a portion of the connecting bracket 420 passes through the movable opening 130.

[0114] When drawer 400 is in the pulled-out position, connecting bracket 420 can be located outside the movable opening 130.

[0115] By setting the movable opening 130, the connecting bracket 420 can pass through the movable opening 130 when the drawer is pushed into place. This ensures that when the drawer body 410 is pushed into place, the connecting bracket 420 can accurately contact the contact end of the control component 300, thereby reliably controlling the opening of the suction device 200, keeping the accommodating space under negative pressure, and improving the sealing effect of the drawer. The design of the movable opening 130 ensures that the connecting bracket 420 always maintains the correct movement trajectory during the pushing and pulling of the drawer body 410, preventing poor sealing effect caused by the drawer body 410 not being pushed into place or the incorrect position of the connecting bracket 420. The design of the movable opening 130 ensures that the connecting bracket 420 is always effectively guided during movement, increasing the reliability of the system, ensuring the stable movement of the connecting bracket 420 within the movable opening 130, and improving the reliability and durability of the system.

[0116] In some possible implementations, the side of the liner 100 may be provided with a shield, which is at least used to shield the control element 300.

[0117] The shielding component is used to cover the control component 300, preventing external environmental influences on it. The shielding component covers the control component 300, preventing dust, moisture, and other external factors from affecting it, thus ensuring the normal operation of the control component 300. This reliably controls the opening of the suction device 200, keeping the containment space under negative pressure and improving the sealing effect of the drawer 400. The design of the shielding component effectively protects the control component 300, extends its service life, and improves system reliability. Furthermore, the shielding component prevents users from accidentally touching the control component 300 while operating the drawer 400, ensuring that the control component 300 maintains the correct working state during the pushing and pulling of the drawer body 410, preventing poor sealing due to misoperation.

[0118] refer to Figure 10 In some possible implementations, the distance between the contact 421 and the rotation axis of the connecting frame 420 is less than the distance between the handle 430 and the rotation axis of the connecting frame 420.

[0119] The distance between the contact 421 and the rotating shaft of the connecting frame 420 is L1, and the distance between the handle 430 and the rotating shaft of the connecting frame 420 is L2, where L1 < L2, thus forming the first force-saving lever.

[0120] Furthermore, the connecting frame 420 has a connecting rod 422, which is used to connect the handle 430 and the connecting frame 420 support rod with a rotating shaft. The connecting rod 422 is used to install the pressure relief device shaft between the two connecting frames 420. The distance between the pressure relief device shaft and the rotating shaft of the connecting frame 420 is L3, where L3 < L2, thus forming a second force-saving lever.

[0121] Since L1 < L2, a labor-saving lever is formed. This means that when the user operates the handle rod 430, a smaller force can be used to achieve a larger acting force, thus more easily controlling the triggering of the control member 300. Since L3 < L2, a second labor-saving lever is further formed, which makes the operation of the pressure relief device shaft rod more labor-saving and ensures that the pressure relief valve can be effectively closed or opened.

[0122] According to the lever principle, the longer the force arm, the smaller the force required. L2 is the distance between the handle rod 430 and the rotation axis of the connecting frame 420, and L1 is the distance between the contact member 421 and the rotation axis of the connecting frame 420. Since L2 > L1, when the user applies a force on the handle rod 430, through the lever action, a smaller force can generate a larger acting force on the contact member 421, thus effectively triggering the control member 300. And because the distance between the contact member 421 and the rotation axis of the connecting frame 420 is short, when the handle rod 430 is operated, the contact member 421 can contact the control member 300 more quickly and accurately. This design ensures that when the drawer body 410 is pushed into place, the contact member 421 can reliably control the opening of the air extraction device 200, making the accommodation space in a negative pressure state and improving the sealing effect of the drawer. The longer distance between the handle rod 430 and the rotation axis of the connecting frame 420 allows the user to apply a larger torque when operating the handle rod 430, thus making it easier to push or pull the drawer. This design improves the sensitivity and convenience of the operation.

[0123] The same principle applies to L3 and L2. Since L3 < L2, when the user pulls the handle rod 430 and operates the pressure relief device shaft rod through the linkage connecting rod 422, a smaller force can generate a larger acting force, thus ensuring the effective control of the pressure relief valve.
