Description

Technical Field

[0001] The utility model relates to the design of an auxiliary closing structure for a ventilation pipeline, in particular to a timing valve. Background Art

[0002] In daily life, there are some safety hazards when using household gas pipelines. People often need to turn off the main gas valve when going out, or forget to turn off the valve when the household gas pipeline is not in use due to negligence, which can easily lead to gas poisoning, fire, explosion and other accidents.

[0003] In the prior art, there are some timed self-closing valves, but since the self-closing valves are small in size and need to realize the timing function, a relatively complex structure is required, resulting in the timing function not being able to effectively realize the closing of the self-closing valve.

[0004] It can be seen that in the prior art, the timed self-closing valve can only be closed through the closing structure inside the self-closing valve. However, in order to add some auxiliary closing functions, such as timed closing, the structure of the entire self-closing valve is complicated, resulting in the self-closing valve being unable to close smoothly, which easily affects the closing effect of the self-closing valve.

[0097] The timing valve of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments of the present invention.

[0098] like Figures 1-18 As shown, the timing valve comprises a self-closing valve body 02 and a timer 03 with a timing function, with the timer 03 connected to the upper side of the valve body 02. It also includes a first drive structure 1 and a second drive structure 2, which interact to transmit driving force to the closing actuator 3; and the closing actuator 3, which closes the gas pipeline. The first drive structure 1 is fixedly connected to the side wall of the rotating housing of the timer 03. The first and second drive structures 1 and 2 drive the closing actuator 3, driving the driving end of the closing actuator 3 to the second drive structure 2. The other end of the closing actuator 3 is provided with a self-closing valve pipeline closing device 4.

[0099] By setting the first drive structure 1 on the side wall of the rotating shell of the timer 03, when the first drive structure 1 reaches the set requirements (for example, when the timing ends), it can act on the second drive structure 2, thereby realizing the driving effect on the closing actuator 3.

[0100] In this application, the timer 03 is provided on the upper side of the valve body 02. The first drive structure 1 is fixedly connected to the outer wall of the timer 03. When the timer 03 rotates to a specified position (preferably when the timing ends), the first drive structure 1 attracts the second drive structure 2, thereby realizing the driving effect of closing the actuator 3.

[0101] Preferably, the first driving structure 1 is arranged at the position of timer zero. When the timer 03 rotates to zero, the first driving structure 1 and the second driving structure 2 act.

[0102] Further preferably, when the timer 02 rotates to zero, the first driving structure 1 and the second driving structure 2 are closest to each other, so that the interaction between the first driving structure 1 and the second driving structure 2 can be better achieved.

[0103] In order to ensure a compact structure and to achieve interaction between the first driving structure 1 and the second driving structure 2 when the first driving structure 1 and the second driving structure 2 reach a set distance (the closest distance), it is preferred that the first driving structure 1 and the second driving structure 2 are magnetic members that attract each other (one is a magnet and the other is a material that can be attracted by the magnet).

[0104] The timer 03 rotates during use. When the timer ends, the distance between the first drive structure 1 and the second drive structure 2 reaches the set distance. The first drive structure 1 attracts the second drive structure 2, thereby driving the closing actuator 3 to close the self-closing valve pipeline 01.

[0105] In order to prevent the timer 03 from interfering with the magnetic component, the rotating shell of the timer 03 is made of non-magnetic material.

[0106] To facilitate the connection of the first drive structure 1, minimize damage to the timer 03, maintain the integrity of the timer 03, and avoid significant changes to the timer 03 that could affect its performance, the rotating housing of the timer 03 has a fixing opening formed in the sidewall adjacent to the second drive structure 2 at the end of the timed rotation. The first drive structure 1 is a magnetic block fixedly connected within the fixing opening.

[0107] In order to avoid affecting the appearance of the timer 03 and reducing the integrity and compactness of the product, the magnetic block is arranged inside the fixed port and sealed on the side wall surface of the rotating shell.

[0108] In one embodiment, the first driving structure 1 and the second driving structure 2 are magnets respectively; although the cost of the two magnets is slightly increased, the magnetic effect is good and can ensure the smooth execution of the driving action.

[0109] In another embodiment, one of the first drive structure 1 and the second drive structure 2 is a magnet and the other is a magnetic material. In other words, as long as the first drive structure 1 and the second drive structure 2 can attract each other when they reach a set distance, this will reduce the cost of selecting permanent magnets. Furthermore, magnetic materials (such as iron blocks) are low-cost.

[0110] In a preferred embodiment, the closing rod 31 for closing the self-closing valve pipeline 01, the fixed rod 32 for hingedly connecting the closing rod 31, and the sliding rod 33 for pushing the closing rod 31, the fixed rod 32 is hingedly connected to the middle part of the closing rod 31, the fixed rod 32 and the self-closing valve pipeline 01 are fixedly connected, the lower end of the closing rod 31 is connected to the self-closing valve pipeline device 4, the upper end of the closing rod 31 is hingedly connected to the sliding rod 33, and the other end of the sliding rod 33 is fixedly connected to the second driving structure 2.

[0111] The second driving structure 2 pulls the sliding rod 33 to slide, and the sliding rod 33 pulls the closing rod 31 to rotate around the end of the fixed rod 32, so that the other end of the closing rod 31 acts on the self-closing valve pipeline 01, thereby closing the self-closing valve pipeline 01.

[0112] In order to support the sliding rod 33 and ensure the stability of sliding. The closing actuator 3 also includes: a support plate 34, the support plate 34 has a support hole, and the sliding rod 33 is arranged through the support hole. The sliding rod 33 is supported by the support hole. In one embodiment, the second drive structure 2 is a permanent magnet (the first drive structure 1 can be a permanent magnet (adsorbed by the second drive structure 2), or it can be a magnetic material such as iron), and the side of the support plate 34 close to the second drive structure 2 is provided with a permanent magnet adsorbed by the second drive structure 2, or the upper end of the support plate 34 is a permanent magnet and is attracted to the second drive structure 2, or the upper end of the support plate 34 is an armature adsorbed by the permanent magnet. That is to say, when the first drive structure 1 adsorbs the second drive structure 2, the adsorption force of the first drive structure 1 is greater than the adsorption force of the support plate 34, so that the sliding rod 33 can be driven under the pull of the first drive structure 1.

[0113] In a preferred embodiment, the second drive structure 2 is a magnet, the first drive structure 1 is an armature, and the support plate 34 is also an armature; the sliding rod 33 is made of a non-magnetic material. This ensures that the second drive structure 2 can be attracted to the first drive structure 1 and the support plate 34 respectively.

[0114] During the timed operation, the first drive structure 1 rotates away from the second drive structure 2. At this time, the suction force of the first drive structure 1 on the second drive structure 2 is less than the suction force of the support plate 34 on the second drive structure 2. Therefore, under the suction force of the support plate 34, the second drive structure 2 drives the sliding rod 33 to slide, thereby driving the closing rod 31 to rotate, opening the self-closing valve pipeline 01 and forming a gas passage.

[0115] In another embodiment, to achieve the same pushing effect on the sliding rod 33, a support ring 35 is provided on the outer wall of the end of the sliding rod 33 near the closing rod 31, and a compression spring 5 is sleeved between the support ring 35 and the support hole. During the process of the first drive structure 1 adsorbing the second drive structure 2, the compression spring 5 is compressed by the support ring 35 and the support hole, storing energy, and the self-closing valve pipeline 01 is closed; after the first drive structure 1 moves away from the second drive structure 2, the second drive structure 2 approaches the support plate 34 under the push of the compression spring 5. At this time, the sliding rod 32 drives the closing rod 31 to rotate, achieving the opening of the self-closing valve pipeline 01. To avoid the problem of the support plate 34 and the second drive structure 2 being in close contact for a long time, causing adhesion between them, a support protrusion is provided on the side of the support plate 34 near the second drive structure 2. This reduces the contact area and ensures that the second drive structure 2 can slide smoothly during the process of the first drive structure 1 adsorbing the second drive structure 2, thereby ensuring the closure of the self-closing valve pipeline 01. In order to seal the closing actuator 3, it is convenient for the closing actuator 3 to extend into the interior of the self-closing valve pipeline 01, thereby realizing the closing and opening of the self-closing valve pipeline 01. It also includes: a sealing shell 6, the sealing shell 6 is sealed and connected to the outer wall of the self-closing valve pipeline 01, and the closing actuator 3 and the second drive structure 2 are both arranged inside the sealing shell 6. The closing actuator 3 is further closed by the sealing shell 6 to avoid external misoperation that affects the execution of the closing actuator 3. Of course, the sealing shell 6 is made of non-magnetic material to ensure that the first drive structure 1 can adsorb the second drive structure 2 inside the sealing shell 6. In order to facilitate the fixed connection of the closing actuator 3, and to facilitate the closing actuator 3 to realize the closing effect on the self-closing valve pipeline 01. A sealing platform 04 is provided on the upper side of the self-closing valve pipeline 01, and a sealing groove 05 is provided on the edge of the sealing platform 04. A sealing ring is provided inside the sealing groove 05, and the sealing shell 6 extends into the sealing groove 05 to compress and seal;

[0116] In order to improve the fixing strength between the sealing shell 6 and the sealing platform 04, a connecting protrusion 7 is provided on the outer wall of the sealing shell 6, and a connecting threaded hole 8 is provided on the edge of the sealing platform 04. A fixing bolt is provided through the connecting protrusion 7 and extends into the threaded hole 8.

[0117] To facilitate closing the self-closing valve conduit 01, the self-closing valve conduit closing device 4 is a sealing cover. To facilitate closing the self-closing valve conduit 01, the actuator 3 is closed. The sealing platform 04 has an access opening 06 on the side away from the timer 03. The closing rod 31 extends through the access opening 06 into the self-closing valve conduit 01 and is fixedly connected to the sealing cover at its lower end. A sealing tube protrudes from the interior of the self-closing valve conduit 01, and a detachable sealing cover is attached to the end of the sealing tube, thereby stably opening and closing the self-closing valve conduit 01.

[0118] Example 1

[0119] like Figure 1 as well as Figure 5-Figure 7 As shown, in order to facilitate the closing of the actuator 3, the direction of movement is changed and the closing structure is not in the same direction to achieve closing. The closing actuator 3 is a wedge mechanism.

[0120] By placing the first drive structure 1 on the mechanism that triggers the requirements, when the first drive structure 1 meets the set requirements, it can pull the second drive structure 2, thereby achieving the driving effect of closing the actuator 3. The wedge mechanism closes the self-closing valve pipeline 01 by changing the direction of movement.

[0121] Here, the triggering mechanism can be a variety of triggering mechanisms. For example, in this application, it can be the self-closing valve's timer 03, located on the upper side of the valve body 02. The first drive structure 1 is fixedly connected to the side wall of the timer 03. When the timer 03 rotates to a specified position, the first drive structure 1 attracts the second drive structure 2, thereby achieving a lateral drive effect on the closing actuator 3. The inclined wedge mechanism then converts the lateral motion into vertical motion, thereby conveniently closing the self-closing valve pipeline 01.

[0122] Preferably, the first driving structure 1 is arranged at the position of timer zero. When the timer 03 rotates to zero, the first driving structure 1 and the second driving structure 2 act.

[0123] Further preferably, when the timer 02 rotates to zero, the first driving structure 1 and the second driving structure 2 are closest to each other, so that the interaction between the first driving structure 1 and the second driving structure 2 can be better achieved.

[0124] In order to ensure a compact structure and to realize the interaction between the first driving structure 1 and the second driving structure 2 when the first driving structure 1 and the second driving structure 2 reach a set distance position (the closest position), it is preferred that the first driving structure 1 and the second driving structure 2 are magnetic members that attract each other.

[0125] The first driving structure 1 and the second driving structure 2 are respectively magnets (one is a magnet, and the other is a material that can be absorbed by the magnet (including a magnet)).

[0126] The timer rotates during use, and when the timer ends, the distance between the first drive structure 1 and the second drive structure 2 reaches the set distance. The first drive structure 1 attracts the second drive structure 2, thereby pulling the closing actuator 3 to close the self-closing valve pipeline 01.

[0127] In one embodiment, the first driving structure 1 and the second driving structure 2 are magnets respectively; although the cost of the two magnets is slightly increased, the magnetic effect is good and can ensure the smooth progress of the driving action.

[0128] In another embodiment, one of the first drive structure 1 and the second drive structure 2 is a magnet and the other is a magnetic material. In other words, as long as the first drive structure 1 and the second drive structure 2 can attract each other when they reach a set distance, this will reduce the cost of selecting permanent magnets. Furthermore, magnetic materials (such as iron blocks) are low-cost.

[0129] Preferably, the closing actuator 3 of the inclined wedge mechanism includes: a horizontal rod 301 and a vertical rod 302. One end of the horizontal rod 301 is fixedly connected to the second drive structure 2. The lower side of the other end of the horizontal rod 301 is provided with an inclined groove structure 303. The upper end of the vertical rod 302 slides in the inclined groove structure 303. The lower side of the vertical rod 302 is connected to the closing self-closing valve pipeline device 4, so that the self-closing valve pipeline 01 is closed or conducted. The horizontal rod 301 is driven to slide horizontally by the second drive structure 2. The inclined groove structure 303 of the horizontal rod 301 can push the vertical rod 302 downward, thereby realizing the up and down movement of the closing self-closing valve pipeline device 4, so that the self-closing valve pipeline 01 can be conveniently closed, meeting the closing conditions of the self-closing valve pipeline 01 (for example, when the timing reaches zero).

[0130] In order to ensure the movement direction of the horizontal rod 301 and the vertical rod 302, avoid deviation, and ensure the stable closing effect on the self-closing valve pipeline 01 during the closing execution layer. The closing actuator 3 also includes: a guide shell 304 that guides the horizontal rod 301 and the vertical rod 302. A horizontal hole 305 is opened on the upper side of the guide shell 304, and a vertical hole 306 is opened in the vertical direction of the guide shell 304. The horizontal hole 305 and the vertical hole 306 are connected, and the horizontal rod 301 slides inside the horizontal hole 305, and the vertical rod 302 slides inside the vertical hole 306. The inclined groove structure 303 of the horizontal rod 301 is provided at the intersection of the horizontal hole 305 and the vertical hole 306.

[0131] To seal the gas flowing out of the gas outlet 012 and the gas inlet 011 to prevent leakage, the system further comprises a sealing shell 6, which is sealedly connected to the outer wall of the self-closing valve pipe 01. The closing actuator 3 and the second drive structure 2 are both located within the sealing shell 6. The sealing shell 6 is made of a non-magnetic material to ensure that the first drive structure 1 can attract and act on the second drive structure 2 within the sealing shell 6.

[0132] To facilitate the up-and-down movement of the wedge mechanism, the horizontal self-closing valve conduit 01 can be closed. This conduit 01 communicates with the sealed housing 6, which has an air inlet 011 and an air outlet 012. The self-closing valve conduit closing device 4 is located at the air outlet 012. This changes the gas flow direction of the self-closing valve conduit 01 to a vertical direction, thereby cooperating with the wedge mechanism to close the self-closing valve conduit 01. Of course, the self-closing valve conduit 01 is sealed between the air inlet 011 and the air outlet 012.

[0133] To facilitate gas flow and guide vertical rod 302, ensuring smooth operation of the wedge mechanism, gas outlet 012 includes: a gas vent 013 for gas flow and a guide hole 014 for guiding vertical rod 302. Guide hole 014 is located at the center of gas outlet 012, with gas vents 013 arranged around guide hole 014. The lower end of vertical rod 302 extends into guide hole 014. A self-closing valve conduit device 4 is located above gas outlet 012, allowing vertical rod 302 to compress, seal, or open gas outlet 012. Multiple gas vents 013 ensure sufficient ventilation.

[0134] To ensure that the closed self-closing valve conduit device 4 is reset, that is, after the wedge mechanism loses its function, the gas outlet 012 can be automatically opened, ensuring that the gas in the self-closing valve conduit 01 remains unimpeded, a reset spring 41 is provided between the closed self-closing valve conduit device 4 and the upper side of the guide hole 014. The reset spring 41 lifts the closed self-closing valve conduit device 4 away from the gas outlet 012, thereby ensuring that the gas outlet 012 remains unimpeded.

[0135] To ensure a sealing effect and to ensure the closure of the ventilation duct 01, the self-closing valve duct device 4 is a sealing membrane. To guide the relatively rigid sealing membrane, a telescopic cavity 307 is defined at the lower end of the guide housing 304. The cavity 307 is larger than the sealing membrane, allowing the sealing membrane to slide within the cavity 307.

[0136] Example 2

[0137] like Figure 1 as well as Figures 8-11 As shown, in order to conveniently close the self-closing valve pipeline 01, ensure the closing effect, reduce the structural complexity of the entire closing actuator 3, and thus reduce the failure rate of the entire product. The closing actuator 3 includes: a closing actuator rod 311 that transmits motion and a cylinder 313 that changes the direction of gas flow in the self-closing valve pipeline 01. To facilitate the sealing and disconnection of the self-closing valve pipeline 01, an exhaust hole 314 is opened on the side of the cylinder 313. One end of the closing actuator rod 311 is fixedly connected to the second drive structure 2;

[0138] The self-closing valve pipeline closing device 4 is a cover 312 that has the function of conducting and closing the self-closing valve pipeline 01;

[0139] The closing actuator rod 311 drives the cover shell 312 to cover or be away from the exhaust hole 314. The sealing and opening of the exhaust hole 314 by the cover shell 312 realizes the circuit closure and conduction effect of the self-closing valve pipeline 01.

[0140] By arranging the first driving structure 1 on the mechanism with triggering requirements, when the first driving structure 1 meets the set requirements, it can pull the second driving structure 2, thereby realizing the driving effect on the closing actuator 3.

[0141] Preferably, the closing actuator 311 comprises a sliding rod 3111 that acts as a guide and a downwardly extending bent head 3112 that seals. One end of the sliding rod 3111 is fixedly connected to the second drive structure 2, and the other end of the sliding rod 3111 is integrally formed with the bent head 3112. The lower end of the bent head 3112 is fixedly connected to the cover 312. The cover 312 is used to close and open the self-closing valve pipeline 01.

[0142] In order to support the slide rod 3111 and ensure the sliding stability of the slide rod 3111, support holes 316 are opened on both sides of the upper end of the cylinder 313. The slide rod 3111 is set through the support holes 316 to ensure the support of the slide rod 3111. To avoid gas leakage at the support holes 316 and the inability to completely shut off the self-closing valve pipeline 01, the support hole 316 and the exhaust hole 314 are not connected, that is, the exhaust hole 314 is only opened downward, ensuring that the gas flows directly into the self-closing valve pipeline 01 through the exhaust hole 314.

[0143] Of course, in order to meet the rebound of the cover 312 and move away from the exhaust hole 314 to achieve the conduction of the self-closing valve pipeline 01, a push spring 42 is installed between the cylinder 313 and the bending head 3112. The push spring 42 is in a compressed state. When the first driving structure 1 and the second driving structure 2 move away from each other and lose the adsorption force, the cover 312 can be pushed by the push spring 42 to meet the conduction of the self-closing valve pipeline 01.

[0144] In order to limit the second drive structure 2 and ensure that when the first drive structure 1 approaches, it can exert sufficient adsorption force on the second drive structure 2, thereby ensuring that the closing execution action of the closing actuator 3 is realized. The closing actuator rod 311 also includes: a limit seat 3113, the lower end of which is fixedly connected to the outer wall of the self-closing valve pipeline 01, and a limit hole is opened on the upper side of the limit seat 3113. The slide rod 3111 passes through the limit hole and limits the second drive structure 2 on the side of the limit hole away from the cylinder 313. When the first drive structure 1 moves away from the second drive structure 2, the push spring 42 pushes the slide rod 3111 to slide, and the position of the second drive structure 2 is limited by the limit seat 3113, thereby limiting the sliding distance of the slide rod 3111. When there is sufficient exhaust space in the exhaust hole 314, the slide rod 3111 can be limited to prevent sliding, ensuring that the first drive structure 1 can stably adsorb the second drive structure 2, thereby meeting the closing of the self-closing valve pipeline 01.

[0145] To ensure a good sealing effect on the exhaust hole 314 and prevent leakage from the exhaust hole 314 when closed, which could prevent the entire self-closing valve pipeline 01 from being disconnected, the upper side of the cylinder 313 near the exhaust hole 314 is a flat structure. The flat end surface of the exhaust hole 314 ensures that the cover 312 can effectively seal the exhaust hole 314.

[0146] To seal the gas flowing out of the gas outlet 012 and the gas inlet 011 to prevent leakage, the system further comprises a sealing shell 6, which is sealedly connected to the outer wall of the self-closing valve pipe 01. The closing actuator 3 and the second drive structure 2 are both located within the sealing shell 6. The sealing shell 6 is made of a non-magnetic material to ensure that the first drive structure 1 can attract and act on the second drive structure 2 within the sealing shell 6.

[0147] To ensure that the cylinder 313 not only conducts gas but also seals the exhaust hole 314, closing the self-closing valve pipe 01, the self-closing valve pipe 01 has an inlet hole 011 and an outlet hole 012 formed inside the sealing shell 6, with the cylinder 313 positioned at the outlet hole 012. Of course, the self-closing valve pipe 01 is sealed between the inlet hole 011 and the outlet hole 012.

[0148] In order to satisfy the connection function of the cylinder 313 and to satisfy the conduction function of the gas through the cylinder 313, the lower end of the cylinder 313 is open and cylindrical. The outer wall of the cylinder 315 is provided with an external thread, and the inner wall of the gas outlet 012 is provided with an internal thread. The lower end of the cylinder 315 is sealed and connected to the inside of the gas outlet 012.

[0149] The opening at the lower end of the cylinder 313 is connected to the exhaust hole 314. The gas is ensured to flow in the self-closing valve pipe 01 as follows: it flows from the air inlet 011 into the sealing shell 6, and then flows from the exhaust hole 314 along the air outlet 012 into the self-closing valve pipe 01, thereby conveniently achieving the sealing and circuit-breaking function of the cover 312.

[0150] Example 3

[0151] like Figure 1 as well as Figure 12-14 As shown, in order to conveniently close the self-closing valve pipeline 01, ensure the closing effect, reduce the structural complexity of the entire closing actuator 3, and thus reduce the failure rate of the entire product, the closing actuator 3 includes: a closing actuator rod 311 that transmits motion, and a cylinder 313 that changes the flow direction of gas in the self-closing valve pipeline 01.

[0152] The self-closing valve pipeline closing device 4 is a cover 312 that has the function of conducting and closing the self-closing valve pipeline 01;

[0153] To facilitate sealing and disconnecting the self-closing valve pipeline 01 (to close the ventilation pipeline 01), a vent hole 314 is formed on the side of the cylinder 313. One end of the closing actuator rod 311 is fixedly connected to the second driving structure 2. The closing actuator rod 311 is placed through the vent hole 314, and the other end of the closing actuator rod 311 is fixedly connected to the cover 312. The closing actuator rod 311 drives the cover 312 to cover or move away from the vent hole 314.

[0154] The closing actuator rod 311 is arranged along the center of the exhaust hole 314. During the pulling action performed by the second driving structure 2, the cover 312 exerts a balanced force on the closing actuator rod 311 on all sides, avoiding the offset of the closing actuator rod 311, improving the closing and sealing effect between the cover 312 and the exhaust hole 314, and improving the stability of the air cut-off of the ventilation pipeline 01.

[0155] Of course, to prevent the closing actuator rod 311 from affecting ventilation, a ventilation gap is provided between the closing actuator rod 311 and the exhaust hole 314 to ensure smooth ventilation and a sufficient ventilation volume when the cover 312 is away from the exhaust hole 314. When the cover 312 is open, gas can flow smoothly through the ventilation gap.

[0156] In a preferred embodiment, the closing actuator 311 includes: a sliding guide 3111, an elastic membrane 3115 that provides a certain degree of elastic deformation and can ensure sealing on both sides during the expansion and contraction process, and a connecting tube 3116 that facilitates the connection and auxiliary function. In order to facilitate the fixed connection of the elastic membrane 3115 and ensure the sealing effect, the outer wall of one end of the sliding rod 3111 is provided with a stepped shaft 3114, the outer wall of the stepped shaft 3114 is provided with an external thread, the inner wall of the connecting tube 3116 is provided with an internal thread, the outer wall of the stepped shaft 3114 is sleeved with the elastic membrane 3115, and the end of the stepped shaft 3114 is threadedly connected to the connecting tube 3116, which presses the elastic membrane 3115. Because the elastic membrane 3115 has a certain deformation space, and can meet the sliding movement of the sliding rod 3111 in this deformation space, and can drive the sliding rod 3111, it avoids the use of other auxiliary driving parts, such as using a spring to provide a restoring force, which increases the number of parts and thus the failure rate of the product. In this embodiment, the elastic properties of the rubber material of the elastic membrane 3112 are utilized to deform the second pulling device 2 during the pulling process, and the elasticity of the elastic membrane 3112 provides a restoring force to provide a driving force for the sliding of the slide rod 3111.

[0157] In order to facilitate the connection between the connecting tube 3116 and the second driving structure 2, the other end of the connecting tube 3116 is fixedly connected to the second driving structure 2. A hole can be opened in the second driving structure 2, and a screw is set through it. The screw and the connecting tube 3116 are threadedly connected, thereby realizing the compression and fixation of the second driving structure 2.

[0158] Of course, in order to realize the driving effect on the cover 312, the other end of the sliding rod 3111 is fixedly connected to the cover 312.

[0159] To ensure that the elastic membrane 3115 drives the slide bar 3111 in a straight line and reduce the possibility of tilting the slide bar 3111, the elastic membrane 3115 is circular in structure with a membrane hole at its center, through which the stepped shaft 3114 is inserted. During the deformation of the elastic membrane 3115, the force acting on the slide bar 3111 is exerted on the axis of the slide bar 3111, thereby driving the cover 312 to slide linearly and achieve a sealing effect.

[0160] To ensure the driving force away from the second drive structure 2, the elastic membrane 3115 allows the slide bar 3111 to open the cover 312 even when the second drive structure 2 is no longer in operation. The elastic membrane 3115, located between the membrane hole and the edge, is convex toward the side closest to the second drive structure 2, allowing the second drive structure 2 to pull with a predetermined amount of deformation. Specifically, when the second drive structure 2 pulls, the elastic membrane 3115 deforms, and this deformation is sufficient to maintain the cover 312 closed. When the second drive structure 2 is no longer in operation, the elastic membrane 3115 elastically recovers, driving the cover 312 to open.

[0161] To further enhance the support effect for the slide bar 3111 and ensure that the slide bar 3111 slides along the axis without deflection, a support frame 317 is fixedly connected or integrally formed with the center of the exhaust hole 314, and the slide bar 3111 passes through the center of the support frame 317. The support function of the support frame 317 ensures the stability of the support for the slide bar 3111. The support frame 317 can be integrally formed with the cylinder 313 or fixedly connected to the cylinder 313, as long as it can meet the ventilation requirements and support the slide bar 3111.

[0162] Of course, to facilitate the installation and fixation of the elastic membrane 3115, a membrane mounting opening 318 is provided on the side of the cylinder 313 away from the exhaust hole 314. The edge of the elastic membrane 3115 is pressed and sealed at the membrane mounting opening 318. The elastic membrane 3115 can deform and expand at the membrane mounting opening 318, avoiding interference from the cylinder 313, and ensuring that the elastic membrane 3115 has a driving force on the slide rod 3111.

[0163] Example 4

[0164] like Figure 1 as well as Figure 15-18As shown, to facilitate the closing of actuator 3, the direction of movement is changed, allowing the closing structure to be closed in different directions. Closing actuator 3 is a downward push mechanism. By placing the first drive structure 1 on the triggering mechanism, when the first drive structure 1 meets the set requirement, it can pull the second drive structure 2, thereby driving the closing actuator 3. By changing the direction of movement, the downward push mechanism closes the self-closing valve pipeline 01.

[0165] The closing actuator 3 includes a pulling member 321 for lateral pulling and a pressing member 322 for rotational movement. One end of the pulling member 321 is fixedly connected to the second drive structure 2, and the other end of the pulling member 321 cooperates to pull the pressing member 322, causing the other end of the pressing member 322 to press downward and rotate. The pressing member 322 pushes downward to close the self-closing valve pipeline device 4, thereby closing the self-closing valve pipeline 01.

[0166] To improve sealing effectiveness and reduce the possibility of gas leakage, while also ensuring the transmission of motion under isolated conditions, the self-closing valve conduit 01 is provided with a mounting groove 016 on its upper side. An air inlet 011 and an air outlet 012 are respectively provided at the bottom of the mounting groove 016. A sealing cover plate 017 is sealed to the upper side of the mounting groove 016. The self-closing valve conduit device 4 extends through the sealing cover plate 017 and into the air outlet 012. Sealing and isolating the air inlet 011 and air outlet 012 within the mounting groove 016 significantly reduces the possibility of gas leakage and improves the product's safety.

[0167] In order to ensure the sealing and realize the transmission of the action and ensure the execution of the closing, the self-closing valve pipeline device 4 includes: a closing rod 43, a closing plug 44 and a membrane 45. The lower end of the closing rod 43 is fixedly connected to the closing plug 44, and the middle part of the closing rod 43 is fixedly connected to the membrane 45.

[0168] The outer wall of the closing rod 43 is driven and connected to the pressing member 322; the size of the pressing member 322 is smaller than the size of the lower side of the outer wall of the closing rod 43, so that the pressing member 322 pushes the closing rod 43 to press down.

[0169] In order to ensure the sealing effect, the sealing cover plate 017 is provided with a membrane hole, and the membrane 45 is sealed and connected inside the membrane hole. Through the deformation of the membrane, the up and down movement of the closing rod 43 can be achieved while ensuring the sealing, thereby meeting the realization of the closing action.

[0170] In order to further improve the sealing effect and ensure the safety of the entire mechanism, the mechanism further includes: a sealing shell 6, the sealing shell 6 is provided on the upper side of the mounting groove 016;

[0171] The closing actuator 3 and the second drive structure 2 are positionally connected inside the sealed shell 6. Of course, the sealed shell 6 is made of non-magnetic material to ensure that the first drive structure 1 can absorb and act on the second drive structure 2 inside the sealed shell 6.

[0172] To facilitate the transition from lateral motion to downward rotation, the pressing member 322 includes a winding portion 323 that acts as a hinged drive, an extension portion 324 that extends to a set length, and a sleeve portion 325 that sleeves onto the outer wall of the closing rod 43 and presses down on the closing rod 43. The extension portion 324 is integrally formed on one side of the winding portion 323, and the sleeve portion 325 is integrally formed on the other end of the extension portion 324. The sleeve portion 325 sleeves onto the outer wall of the closing rod 43.

[0173] In order to better limit the winding portion 323, the entire pressing member 322 rotates around the winding portion 323 to achieve the downward pressing action. A limiting shaft 61 is provided in the middle of the sealing shell 6. The middle of the winding portion 323 is wound around the outer wall of the limiting shaft 61. The other end of the winding portion 323 extends downward to engage with the pulling member 321.

[0174] To support the pull member 321 and ensure that it can slide along a plane, improving the driving effect, and conveniently fix the limiting shaft 61, reducing the processing complexity of the sealing shell 6, the sealing shell 6 has a support seat 9 clamped on its lower side. The upper side of the support seat 9 is fixedly connected to the limiting shaft 61 and supports the pull member 321.

[0175] To ensure coordination with the second drive structure 2, particularly with the winding portion 323, and to pull the pressing member 322, the pulling member 321 comprises an integrally formed drive head 326, an extension plate 327, and a connector 328. The extension plate 327 extends upward from both ends of the drive head 326 and the connector 328. The connector 328 is fixedly connected to the second drive structure 2, and the drive head 326 drives the winding portion 323. The lower bottom of the extension plate 327 slides along the support base 9.

[0176] Example 5

[0177] Figure 11 as well as Figures 19-22 As shown, the self-closing valve includes: a closing actuator 3 that can realize the closing effect on the self-closing valve pipeline 01; a first driving structure 1 and a second driving structure 2 that transmit driving force to the closing actuator 3 through interaction, the first driving mechanism 1 and the second driving structure 2 have a driving effect (here mainly a pushing effect), and the driving end of the closing actuator 3 is fixedly connected to the second driving structure 2; thereby driving the action of the closing actuator 3 through the second driving structure 2.

[0178] In order to facilitate the closing of the ventilation duct 01 and ensure the closing effect, the structural complexity of the entire closing actuator 3 is reduced, thereby reducing the failure rate of the entire product. The closing actuator 3 includes: a closing actuator rod 311 that transmits motion, a cover 312 that has a conducting and closing effect on the ventilation duct 01, and a cylinder 313 that changes the direction of gas flow in the ventilation duct 01. In order to facilitate the sealing and disconnection of the ventilation duct 01, an exhaust hole 314 is opened on the side of the cylinder 313. One end of the closing actuator rod 311 is fixedly connected to the second drive structure 2, and the closing actuator rod 311 drives the cover 312 to cover or move away from the exhaust hole 314. The sealing and opening of the exhaust hole 314 by the cover 312 realizes the circuit breaking, closing, and conducting effect of the ventilation duct 01.

[0179] To achieve both limiting and pushing functions, the first drive structure 1 is an annular groove structure 11 (e.g., a protruding annular groove is provided on the side of the timer 03 housing of the valve body 02). A groove 12 is defined within the annular groove structure 11. The end of the second drive structure 2 slides along the annular groove structure 11, either extending into or sliding out of the groove 12. When the timer reaches zero, the second drive structure 2 slides along the annular groove structure 11 into the groove 12, achieving the desired closing action on the self-closing valve pipeline.

[0180] To ensure proper coordination with the annular groove structure 11 and to ensure a sealed state at both ends of the second drive structure 2, preventing gas leakage, the second drive structure 2 comprises a slider 21 that slides along the annular groove structure 11, a sliding rod 22 that extends a predetermined length, and a telescopic membrane 23 that isolates the two ends of the sliding rod 22. The spherical slider 21 is fixedly connected to one end of the sliding rod 22, while the other end of the sliding rod 22 is fixedly connected to the closing actuator 311. The outer wall of the sliding rod 22 is sealed and fixedly connected to the telescopic membrane 23. As the sliding rod 22 slides, the telescopic membrane 23 deforms, ensuring a sealed and isolated state between the two ends.

[0181] In order to achieve a sealing effect on the closing actuator 3 and ensure the working sealing requirements, it also includes: a sealing shell 6, which is sealed and connected to the outer wall of the self-closing valve pipeline 01, and the closing actuator 3 is arranged inside the sealing shell 6; in order to meet the extension of the sliding rod 22 and the coordination between the first driving structure 1, a driving hole is opened through the sealing shell 6, and the sliding rod 22 extends along the driving hole;

[0182] Furthermore, to ensure the secure connection of the telescopic membrane 23 and the sealing housing 6 while ensuring the extension of the slide rod 22, the second drive structure 2 also includes a compression housing 24 that compresses and seals the telescopic membrane 23. The edge of the telescopic membrane 23 is compressed and sealed against the edge of the drive hole by the compression housing 24, and the end of the slide rod 22 is disposed through the compression housing 24. The telescopic membrane 23 not only seals the sealing housing 6 but also compresses and secures the membrane 23, thereby ensuring the sliding action of the slide rod 22 and maintaining the sealing effect of the sealing housing 6.

[0183] To achieve zero time, the second drive structure 2 drives the closing actuator 3 to close the ventilation line. This second drive structure 2 also includes a tension spring 25, which provides a pulling force. The tension spring 25 is mounted on the outer wall of the slide rod 22. One end of the tension spring 25 is fixedly connected to the inner wall of the compression housing 24, and the other end is fixedly connected to the outer wall of the slide rod 22, causing the tension spring 25 to pull the slide rod 22 to slide. The tension spring 25 applies a driving force to the slide rod 22. When the support of the annular groove structure is lost, the tension spring 25 pulls the slide rod to slide, causing the closing actuator 3 to close the self-closing valve line 01.

[0184] Preferably, the closing actuator 311 includes a sliding rod 3111 that acts as a guide and a downwardly extending bent head 3112 that seals the sliding rod 3111. One end of the sliding rod 3111 is fixedly connected to the sliding rod 22, and the other end of the sliding rod 3111 is integrally formed with the bent head 3112. The lower end of the bent head 3112 is fixedly connected to the cover 312. The cover 312 is used to close and open the self-closing valve pipeline 01.

[0185] In order to support the slide rod 3111 and ensure the sliding stability of the slide rod 3111, support holes 316 are opened on both sides of the upper end of the cylinder 313. The slide rod 3111 is set through the support holes 316 to ensure the support of the slide rod 3111. To avoid gas leakage at the support holes 316 and the inability to completely shut off the self-closing valve pipeline 01, the support hole 316 and the exhaust hole 314 are not connected, that is, the exhaust hole 314 is only opened downward, ensuring that the gas flows directly into the self-closing valve pipeline 01 through the exhaust hole 314.

[0186] In order to support the sliding rod 3111, the closing execution rod 311 also includes: a limit seat 3113, the lower end of the limit seat 3113 is fixedly connected to the outer wall of the self-closing valve pipeline 01, and a limit hole is opened on the upper side of the limit seat 3113, and the sliding rod 3111 passes through the limit hole.

[0187] To ensure a good sealing effect on the exhaust hole 314 and prevent leakage from the exhaust hole 314 when closed, which could prevent the entire self-closing valve pipeline 01 from being disconnected, the upper side of the cylinder 313 near the exhaust hole 314 is a flat structure. The flat end surface of the exhaust hole 314 ensures that the cover 312 can effectively seal the exhaust hole 314.

[0188] To ensure that the cylinder 313 not only conducts gas but also seals the exhaust hole 314, closing the self-closing valve pipe 01, the self-closing valve pipe 01 has an inlet hole 011 and an outlet hole 012 formed inside the sealing shell 6, with the cylinder 313 positioned at the outlet hole 012. Of course, the self-closing valve pipe 01 is sealed between the inlet hole 011 and the outlet hole 012.

[0189] In order to satisfy the connection function of the cylinder 313 and to satisfy the conduction function of the gas through the cylinder 313, the lower end of the cylinder 313 is open and cylindrical. The outer wall of the cylinder 315 is provided with an external thread, and the inner wall of the gas outlet 012 is provided with an internal thread. The lower end of the cylinder 315 is sealed and connected to the inside of the gas outlet 012.

[0190] The opening at the lower end of the cylinder 313 is connected to the exhaust hole 314. The gas is ensured to flow in the self-closing valve pipe 01 as follows: it flows from the air inlet 011 into the interior of the sealing shell 6, and then flows from the exhaust hole 314 along the air outlet 012 into the self-closing valve pipe 01, thereby conveniently achieving the sealing and circuit-breaking function of the cover 312.

[0191] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
