Technical Field

[0001] This case relates to valve structure. Background Technology

[0002] A valve is a common structure that allows or prevents fluid flow by applying a driving force to control its opening and closing.

[0003] Existing valve structures often suffer from drawbacks due to their internal flow channels or structural design, such as high fluid flow resistance, high driving force requirements, poor leak-proof effect, high noise levels, or insufficient service life. Therefore, improvements are needed. Summary of the Invention

Therefore, they should not be construed as limitations on this application.

[0124] See Figures 1 to 4 , Figure 1 This is a perspective view of one embodiment of the valve structure of this application; Figure 2 This is a cross-sectional schematic diagram of the actuator in a first position according to an embodiment of the valve structure of this application; Figure 3 for Figure 2 A magnified view of a selected area (3) in the center circle; Figure 4This is a cross-sectional schematic diagram of the actuator in a second position according to an embodiment of the valve structure of this application. This application provides a valve structure suitable for fluid valves that allow fluid flow and control opening and closing. The valve structure includes a housing assembly 10, a drive assembly 20, and a linkage assembly 30. The housing assembly 10 has an internal space S, a flow channel P, a fluid inlet 1112, a fluid outlet 1132, and a valve cover 12. The flow channel P extends along a first direction D1 and communicates with the internal space S. The fluid inlet 1112 passes through the housing assembly 10 and connects to one end of the flow channel P. The fluid outlet 1132 passes through the housing assembly 10 and connects to the other end of the flow channel P. The valve cover 12 is located between the internal space S and the flow channel P and has a receiving groove. The drive assembly 20 is disposed within the internal space S of the housing assembly 10, displaceable along a second direction D2 perpendicular to the first direction D1. The drive assembly 20 has a drive portion 211, the extension direction of which forms an angle with the second direction D2. The linkage assembly 30 includes a connecting rod 31 and a seal 32. The connecting rod 31 includes a first end 311, a second end 312, and a spherical protrusion 3131 located between the first end 311 and the second end 312. The first end 311 is displaceably housed within the driving part 211, and the spherical protrusion 3131 is rotatably housed within a receiving groove. The second end 312 extends into the flow channel P through the valve cover 12. The sealing element 32 is sleeved on the second end 312 of the connecting rod 31. When the drive assembly 20 moves along the second direction D2, the drive assembly 20 drives the first end 311 of the connecting rod 31 to move along the first direction D1 via the driving part 211, while the second end 312 can drive the sealing element 32 to open or close the flow channel P.

[0125] This provides a labor-saving and durable valve structure.

[0126] See Figures 1 to 4 The housing assembly 10 provides space for the actuation of the drive assembly 20 and for the passage of fluid. In some embodiments, the housing assembly 10 includes a valve body 11, a valve cover 12, a first housing 13, and a second housing 14. The valve body 11 has a flow channel P, the valve cover 12 is disposed in the valve body 11, and the internal space S is located within the first housing 13 and the second housing 14. The first housing 13 is assembled with the valve cover 12, and the second housing 14 is assembled with the first housing 13.

[0127] See Figures 1 to 4 and cooperate Figure 10 and Figure 11 , Figure 10 This is a perspective view of an embodiment of the valve body of the valve structure of this application; Figure 11This is a cross-sectional schematic diagram of an embodiment of the valve body of the valve structure of this application. In some embodiments, the valve body 11 includes an inlet pipe 111, a main body 112, and an outlet pipe 113 connected in sequence. The inlet pipe 111 has a first channel 1111, the main body 112 has a main channel space 1121, and the outlet pipe 113 has a second channel 1131. The first channel 1111, the main channel space 1121, and the second channel 1131 are interconnected to form a flow channel P. The inlet pipe 111 has a fluid inlet 1112 and a valve inlet 1113. The fluid inlet 1112 is located at the end of the first channel 1111 away from the main body 112, and the valve inlet 1113 is located at the end of the first channel 1111 that connects to the main channel space 1121. The outlet pipe section 113 has a fluid outlet 1132 and a valve outlet 1133. The fluid outlet 1132 is located at the end of the second channel 1131 away from the main body 112, and the valve outlet 1133 is located at the end of the second channel 1131 that connects to the main channel space 1121. Fluid enters the valve body 11 through the fluid inlet 1112, and then sequentially passes through the first channel 1111, the valve inlet 1113, the main channel space 1121, the valve outlet 1133, and the second channel 1131 before being output from the fluid outlet 1132. The main channel space 1121 provides space for the seal 32 of the linkage assembly 30 to swing to open or close the valve outlet 1133.

[0128] See Figures 1 to 4 and cooperate Figure 10 and Figure 11 In some embodiments, the valve body 11 has a valve opening 114 located in the main body 112 and communicating with the main channel space 1121. In these embodiments, the valve cover 12 can cover the valve opening 114 and cooperate with the seal 32 of the linkage assembly 30 to close the valve opening 114.

[0129] See Figures 1 to 4 In some embodiments, the drive assembly 20 includes a drive member 21, which is displaceable within the internal space S along the second direction D2. The drive member 21 has a drive portion 211, which is an oblique channel with angles to both the first direction D1 and the second direction D2. The drive portion 211 has an opening 2111, an inner surface 2112, and a bottom surface 2113. The inner surface 2112 and the bottom surface 2113 of the channel-shaped drive portion 211 are both arc surfaces. In these embodiments, the opening 2111 of the drive portion 211 opens towards the valve cover 12, and the extension direction from the opening 2111 to the bottom surface 2113 has angles to both the first direction D1 and the second direction D2. That is, the drive portion 211 is inclined relative to the first direction D1 and the second direction D2, and the opening 2111 and the bottom surface 2113 of the drive portion 211 are located at different positions in the first direction D1.

[0130] In some embodiments, the drive member 21 of the drive assembly 20 further includes a relief portion 212, which connects to the opening 2111 of the drive member 211 and extends along the first direction D1. In these embodiments, the relief portion 212 is a groove, thereby providing a smoother swing displacement space for the connecting rod 31 of the linkage assembly 30 and improving the smoothness of the valve structure's operation.

[0131] See Figures 1 to 4 and cooperate Figure 5 , Figure 5 This is a schematic diagram of one embodiment of the connecting rod of the valve structure of this application. In some embodiments, the first end 311 of the connecting rod 31 is a spherical structure, and the second end 312 of the connecting rod 31 is a cylindrical structure. In these embodiments, the connecting rod 31 also includes a connecting portion 313, which is a sheet structure, with spherical protrusions 3131 protruding from opposite sides of the connecting portion 313. Furthermore, the connecting portion 313 of the connecting rod 31 extends in thickness along the thickness direction, which is perpendicular to the opposite sides of the connecting portion 313, while the axial direction of the cylindrical second end 312 is perpendicular to the thickness direction of the connecting portion 313. Thus, the overall shape of the connecting rod 31 can be changed by changing the length of the first end 311, thereby changing the overall length of the connecting rod 31. By changing the length of the connecting rod 31, the force with which the connecting rod 31 drives the sealing element 32 to seal the valve outlet 1133 can be changed. In some embodiments, if the length of the connecting rod 31 is increased when the internal space S allows, the force exerted by the connecting rod 31 on the sealing valve outlet 1133 by the sealing element 32 will increase accordingly. This reduces the driving force required to displace the driving assembly 20, thereby saving effort.

[0132] In these embodiments, the spherical protrusion 3131 corresponding to the groove of the valve cover 12 is spherical. Here, the first end 311 of the connecting rod 31 extends into the driving part 211 through the opening 2111 of the driving part 211, and the second end 312 of the connecting rod 31 passes through the valve cover 12 and extends into the main channel space 1121 of the valve body 11. The sealing member 32 is sleeved on the second end 312 of the connecting rod 31 within the main channel space 1121, and the spherical protrusion 3131 of the connecting rod 31 is rotatably accommodated in the groove. Thus, when the driving member 21 of the drive assembly 20 is displaced along the second direction D2, the driving member 21 is displaced by the driving part 211 covering the first end 311 of the connecting rod 31. When the driving member 21 is displaced, the different positions of the first end 311 of the connecting rod 31 relative to the driving part 211 cause the first end 311 of the connecting rod 31 to change position along the first direction D1, thereby forming a swing.

[0133] See Figures 1 to 5 Specifically, the driving member 21 of the drive assembly 20 can be displaced along the second direction D2 between the first position L1 and the second position L2, with the driving member 21 being closer to the valve body 11 in the first position L1 compared to the second position L2. (See reference...) Figure 2In the first position L1, the first end 311 of the connecting rod 31 is close to the bottom surface 2113 of the driving part 211, and the second end 312 of the connecting rod 31 and the seal 32 thereon are close to the valve outlet 1133 of the valve body 11. The seal 32 closes the valve outlet 1133, so that the flow channel P of the valve body 11 becomes closed (i.e., the fluid cannot pass freely through the valve body 11).

[0134] See Figures 1 to 5 In the second position L2, the driving part 211 of the driving member 21 changes to cover the first end 311 of the connecting rod 31 near the opening 2111. Since the opening 2111 and the bottom surface 2113 of the driving part 211 are located at different positions in the first direction D1, the first end 311 of the connecting rod 31 located in the driving part 211 is driven and its position in the first direction D1 is changed. Furthermore, the connecting rod 31 rotates around the spherical protrusion 3131 as the center, while the second end 312 swings synchronously. In this way, while the driving member 21 drives the connecting rod 31 to swing, the sealing member 32 located at the second end 312 of the connecting rod 31 can change its state of opening or closing relative to the valve outlet 1133 of the valve body 11, thereby achieving the purpose of opening and closing the valve body 11 to control the fluid.

[0135] See 2 to Figure 4 and cooperate Figures 6 to 9 , Figure 6 This is a schematic diagram of the appearance of an embodiment of the sealing element of the valve structure of this application; Figure 7 This is a schematic diagram from another perspective of an embodiment of the sealing element of the valve structure of this application; Figure 8 A cross-sectional view of an embodiment of the sealing element of the valve structure of this application. Figure 1 ; Figure 9 A cross-sectional view of an embodiment of the sealing element of the valve structure of this application. Figure 2 In some embodiments, the seal 32 is made of a flexible material. Here, the seal 32 includes a first portion 321 and a second portion 322 connected to each other. The first portion 321 is a sheet structure, and the second portion 322 is a hollow block structure. In these embodiments, the first portion 321 is located between the valve cover 12 and the valve body 11, and the second portion 322 is deformable relative to the first portion 321. The second end 312 of the connecting rod 31 passes through the first portion 321 and is inserted into the second portion 322. Thus, when the actuator 21 drives the connecting rod 31 to swing, the connecting rod 31 causes the second portion 322 of the seal 32 to deform relative to the first portion 321, allowing it to move away from or abut against the valve outlet 1133 of the valve body 11.

[0136] See Figures 6 to 11In some embodiments, the main body 112 of the valve body 11 has a positioning edge 1122, which protrudes from the surface of the main body 112 of the valve body 11 near the valve opening 114. The outer surface of the positioning edge 1122 is rectangular. The positioning edge 1122 has a first inner surface 11221 and a second inner surface 11222. The first inner surface 11221 is near the valve opening 114, and the second inner surface 11222 connects to the first inner surface 11221. In these embodiments, the inner circumferential contour of the first inner surface 11221 corresponds to the outer circumferential contour of the first part 321 of the seal 32, and the shapes of the inner circumferential contour of the first inner surface 11221 and the outer circumferential contour of the first part 321 of the seal 32 are not circular. In this way, when the first part 321 of the seal 32 is located between the valve body 11 and the valve cover 12, the seal 32 can be accommodated between the first inner surface 11221 of the positioning edge 1122, and at the same time, it can be restricted from rotating by its appearance shape, ensuring that the seal 32 can be stably deformed when subjected to force, and ensuring the opening and closing effect of the valve body 11.

[0137] See Figures 2 to 4 and Figures 6 to 9 In some embodiments, the first portion 321 of the seal 32 has a through hole 3211 and opposing upper and lower surfaces 3212 and 3213. The through hole 3211 penetrates the upper and lower surfaces 3212 and 3213. The lower surface 3213 is planar. The upper surface 3212 has an arcuate convex portion 32121 and an annular recess 32122. The annular recess 32122 surrounds the through hole 3211 and surrounds the arcuate convex portion 32121. In these embodiments, the end face of the arcuate convex portion 32121 away from the lower surface 3213 is an arcuate surface. Therefore, when the seal 32 is disposed between the valve body 11 and the valve cover 12, the lower surface 3213 of the first part 321 of the seal 32 abuts against the valve body 11, and the upper surface 3212 abuts against the valve cover 12. In this way, the valve cover 12 will abut against the arcuate protrusion 32121 of the upper surface 3212 of the first part 321 of the seal 32. In this way, the contact area between the valve cover 12 and the seal 32 is reduced, and the seal 32 is prevented from being pressed tightly, which would affect the deformation of the second part 322. This ensures that the second part 322 can reliably deform under force to complete the opening and closing of the valve body 11.

[0138] See Figures 2 to 4 and Figures 6 to 9In some embodiments, the second portion 322 of the seal 32 includes a first groove 3221, a second groove 3222, and a spacer wall 3223. The first groove 3221 is formed along a second direction D2, the second groove 3222 is formed along a first direction D1, and the spacer wall 3223 is located between the first groove 3221 and the second groove 3222. In these embodiments, the inner circumferential contour of the first groove 3221 corresponds to the shape of the second end 312 of the connecting rod 31, so that the second end 312 of the connecting rod 31 can be inserted into the first groove 3221 of the seal 32 and can reliably apply force to the seal 32 to cause the seal 32 to deform.

[0139] See Figures 2 to 9 In some embodiments where the second end 312 of the connecting rod 31 is cylindrical, the first groove 3221 has a first inner surface 32211, and the second groove 3222 has a second inner surface 32221. The first inner surface 32211 is circular around the second direction D2, and the second inner surface 32221 is circular around the first direction D1. In this way, the first groove 3221 can tightly engage the second end 312 of the connecting rod 31, while the second groove 3222 can improve the elasticity of the seal 32, absorb the force when the seal 32 impacts and closes the valve outlet 1133, reduce the wear of the seal 32, and ensure the sealing effect of the seal 32 on the valve outlet 1133.

[0140] See Figures 2 to 4 and Figures 6 to 9 In some embodiments, the second portion 322 of the seal 32 further includes an end face 3224, a first flange 3225, a second flange 3226, and an annular groove 3227. The end face 3224 surrounds the end of the second groove 3222 away from the spacer wall 3223. The first flange 3225 protrudes from the end face 3224 and is located at the end of the end face 3224 away from the second groove 3222. The second flange 3226 protrudes from the end face 3224 and is located at the end of the end face 3224 adjacent to the second groove 3222. The annular groove 3227 is defined between the first flange 3225 and the second flange 3226. In this way, when the seal 32 closes the valve outlet 1133, the seal 32 abuts against the periphery of the valve outlet 1133 with its end face 3224, and the first flange 3225 and the second flange 3226 can provide a double-layer leak-proof effect, while the annular groove 3227 can block the flow of fluid, thereby effectively improving the leak-proof effect.

[0141] In some embodiments where the seal 32 includes a first flange 3225 and a second flange 3226, the junction of the first flange 3225 and the annular groove 3227 has a first included angle, and the junction of the second flange 3226 and the annular groove 3227 has a second included angle, with the first included angle being greater than the second included angle. This allows the second flange 3226 to effectively prevent fluid passage when the first flange 3225 fails to prevent leakage, providing a double-layer leak-proof effect.

[0142] See Figures 2 to 4 and Figures 6 to 9 In some embodiments, the second flange 3226 includes a connecting section 32261 and an extension section 32262. The connecting section 32261 connects to the annular groove 3227, and the extension section 32262 overlaps the annular groove 3227 in the second direction D2 by more than 50% of the total length of the annular groove 3227 in the second direction D2. This makes the end of the second flange 3226 extending into the annular groove 3227 more flexible and elastic, thereby allowing it to fit more tightly around the valve outlet 1133 and improving the leak-proof effect.

[0143] See Figures 2 to 4 and Figures 6 to 9 In some embodiments, the partial outer contour of the first portion 321 of the seal 32 is generally circular. Here, the partial circular outer contour of the first portion 321 of the seal 32 has a center, and the first groove 3221 of the second portion 322 has an axis passing through the center of the first portion 321. The portion of the second portion 322 where the second groove 322 is located is situated on one side of the portion of the second portion 322 where the first groove 322 is located. In the first direction D1, the center of the first portion 321 and the portion of the second portion 322 where the second groove 322 is located do not overlap. In these embodiments, when the seal 32 is fitted onto the connecting rod 31 within the flow channel P, the portion of the second portion 322 where the second groove 322 is located is closer to the fluid outlet 1132 than the portion of the second portion 322 where the first groove 322 is located. In this way, when the seal 32 is open, the distance between the end face 3224 of the seal 32 and the valve outlet 1133 can be shortened, thereby improving the response speed of the seal 32. In addition, the space between the side of the seal 32 where the first groove 3221 is provided and the valve inlet 1113 can be expanded, reducing the resistance of fluid entering the valve body 11 and the required driving force, thereby better meeting the energy-saving effect.

[0144] See Figures 2 to 4 and Figures 6 to 9In some embodiments, the second portion 322 of the seal 32 has a portion of the second groove 3222 formed into a cylinder around a first direction D1. The aforementioned portion of the outer peripheral surface of the second portion 322 further includes a first groove 3228 and a second groove 3229. In the second direction D2, the first groove 3228 is closer to the valve cover 12 than the second groove 3229, and the first groove 3228 has a first groove width in the first direction D1, while the second groove 3229 has a second groove width in the first direction D1. The first groove width may, but is not limited to, be equal to or not equal to the second groove width. This allows for adjustment of the elasticity of different positions of the portion of the seal 32 having the second groove 3222. In some embodiments, the width of the first groove is smaller than the width of the second groove. Therefore, when the connecting rod 31 drives the seal 32 to swing and abut against the valve outlet 1133, the side of the seal 32 with the second groove 3229 contacts the area around the valve outlet 1133 first and bears a greater force. Thus, the side of the seal 32 with the second groove 3229 provides a larger deformation space for the seal 32, thereby balancing the force on the contact surface when the seal 32 abuts against the area around the valve outlet 1133. Under the condition of balanced force on the contact surface when the seal 32 abuts against the area around the valve outlet 1133, unilateral wear of the seal 32 is reduced, extending the durability and lifespan of the seal 32.

[0145] See Figures 2 to 4 and Figures 6 to 9 In some embodiments, the second portion 322 of the seal 32 further includes a reinforcing rib 32291 disposed within the second groove 3229, thereby locally increasing the strength of the portion of the second portion 322 with the second groove 3229. Thus, when the actuating member 21 moves from the first position L1 to the second position L2 to separate the seal 32 from the valve outlet 1133, the portion of the second portion 322 with the second groove 3229 of the seal 32 has higher strength, allowing it to be smoothly driven away from the valve outlet 1133 when the connecting rod 31 actuates the seal 32. This reduces the force required for the driving assembly 20 to drive the linkage assembly 30 to open the valve outlet 1133, achieving a labor-saving effect in opening the valve body 11.

[0146] It is worth noting that the second part 322 of the seal 32 may also not have the second groove 3222 (i.e., the second groove 3222 is a solid structure). In order to adjust the elasticity of the seal 32 or to be suitable for different processing methods, the elasticity provided by the second groove 3222 can be replaced by increasing the number of the first groove 3228 and the second groove 3229 on the local outer surface where the second groove 3222 is provided. However, this case is not limited to this.

[0147] See Figure 3In other embodiments, the second portion 322 of the seal 32 may also be provided with a second groove 3222, a first groove 3228, and a second groove 3229. Furthermore, an inner ring groove 32222 may be further provided on the second inner surface 32221 of the second groove 3222, thereby allowing the second portion 322 of the seal 32 to have different elastic characteristics. That is, the seal 32 may be provided with one or a combination of the second groove 3222, the first groove 3228, the second groove 3229, or the inner ring groove 32222 on the second inner surface 32221, to adjust for different elastic characteristics and suit different needs.

[0148] See Figures 2 to 4 In some embodiments, the valve structure uses pneumatic pressure to drive the drive assembly 20 to move along a second direction D2. In these embodiments, a spring 40 is partially sleeved on the drive member 21 and housed within a first housing 13, while a portion extends out of the first housing 13 and is housed within a second housing 14. A slider capable of moving along the second direction D2 is disposed within the second housing 14 and connected to the partial drive member 21 within the second housing 14. The second housing 14 has a second air inlet 141. Thus, when driving gas is input from the second air inlet 141, the driving gas pushes the slider away from the first housing 13, causing the slider to move the drive member 21 from a first position L1 to a second position L2, simultaneously compressing the spring 40 to accumulate elastic force. When the driving gas input to the second air inlet 141 stops, the spring 40 releases its elastic force, causing the drive member 21 to return from the second position L2 to the first position L1.

[0149] In some embodiments, since the spring 40 is mostly made of metal, in order to avoid the metal spring 40 in the valve structure from having an adverse effect on the process of using the valve structure, in some embodiments, the drive member 21 may not be fitted with the spring 40, and the first housing 13 has a first air inlet 131. In this way, when the air pressure source is input from the first air inlet 131, the drive gas pushes the drive member 21 away from the second housing 14, and the drive member 21 is displaced from the second position L2 to the first position L1, thereby completing the driving of the drive member 21.

[0150] It is worth noting that the aforementioned embodiment is described using the pneumatically driven valve structure drive component 20 as an example. In other embodiments, the valve structure may not be limited to the pneumatically driven drive component 20 for displacement. For example, the valve structure may be manually driven by the drive component 20.

[0151] See Figures 12 to 14 , Figure 12 This is a cross-sectional schematic diagram of the actuator in a first position, representing another embodiment of the valve structure of this application. Figure 13 This is a cross-sectional schematic diagram of the actuator in the second position, representing another embodiment of the valve structure of this application. Figure 14 This is a schematic diagram of another embodiment of the connecting rod of the valve structure of this application. In some embodiments, the connecting rod 31 further includes a groove 314 and a first stop portion 315, the groove 314 being located on one side of the spherical protrusion 3131, and the first stop portion 315 being located on one side of the groove 314. In these embodiments, the valve cover 12 includes a first component 121 and a second component 122, the first component 121 having a second stop portion 1211, and the first stop portion 315 and the second stop portion 1211 overlapping in a first direction D1. In this way, when the driving member 21 is displaced from the first position L1 to the second position L2, or from the second position L2 to the first position L1, the first stop portion 315 of the connecting rod 31 will contact the second stop portion 1211 of the valve cover 12, and when the first stop portion 315 contacts the second stop portion 1211, the position of the connecting rod 31 corresponding to the first stop portion 315 is compressed and deformed toward the groove 314. In this way, the connecting rod 31 can absorb the force during the swinging process through deformation, thereby slowing down the swinging speed of the connecting rod 31, reducing the impact of water hammer caused by fluid pressure on the seal 32, reducing the noise generated when the valve structure is opened and closed, reducing the wear of the seal 32, and extending the service life of the valve structure.

[0152] See Figure 10 , Figure 11 In some embodiments, the main channel space 1121 of the main body 112 of the valve body 11 is curved and expanded at the junction with the first channel 1111. Specifically, the main channel space 1121 extends from the valve opening 114 along the second direction D2. In these embodiments, the valve opening 114 is generally arch-shaped, and the range of the main channel space 1121 can be defined by the plane 11211 and the arc-shaped surface 11212, the arc-shaped surface 11212 being arched, and the two ends of the arc-shaped surface 11212 connecting to the two ends of the plane 11211. Here, the valve outlet 1133 is located on the plane 11211, and the valve inlet 1113 is located on the arc-shaped surface 11212. The distance between the fluid outlet 1132 and the valve outlet 1133 in the first direction D1 is greater than the distance between the valve inlet 1113 and the fluid inlet 1112 in the first direction D1. This achieves a side-bending arc expansion of the main channel space 1121 at the valve inlet 1113. This reduces the flow resistance of the fluid entering the main channel space 1121 from the first channel 1111, thereby reducing the driving force required to displace the drive assembly 20. Furthermore, the expansion at the junction of the main channel space 1121 and the first channel 1111 allows for an increased swing amplitude of the connecting rod 31, thereby increasing the smoothness of fluid flow when the valve body 11 is open.

[0153] See Figures 15 to 17 , Figure 15 This is a perspective cross-sectional view of an embodiment of the first component of the valve cover of this application; Figure 16 A perspective view of an embodiment of the second component of the valve cover of this application; Figure 17 This is a schematic diagram of the appearance of one embodiment of the first component of the valve cover 12. In some embodiments, the first component 121 of the valve cover 12 has a first passage 1212, which extends through the first component 121 and includes a first side opening 12121, a first sleeve opening 12122, and a second side opening 12123 connected in sequence. The first sleeve opening 12122 includes two opposing arcuate profiles, and the first side opening 12121 and the second side opening 12123 extend straight along opposite sides of the first sleeve opening 12122 into rectangular openings. In these embodiments, the spherical protrusion 3131 of the connecting rod 31 can rotatably abut against the first sleeve opening 12122, while the first side opening 12121 and the second side opening 12123 provide space for the connecting rod 31 to swing in both directions. In these embodiments, the second stop 1211 is a protrusion structure that protrudes into the first passage 1212 from the edge of the first side opening 12121.

[0154] In some embodiments, the second component 122 of the valve cover 12 has a second passage 1221, which penetrates the second component 122 and includes a limiting opening 12211, a second sleeve 12212, and an expansion opening 12213 connected in sequence. The second sleeve 12212 includes two opposing arcuate profiles. The outer profile of the limiting opening 12211 corresponds to the cross-sectional shape of the connecting portion 313 of the connecting rod 31. The expansion opening 12213 expands relative to the limiting opening 12211. In these embodiments, the spherical protrusion 3131 of the connecting rod 31 can rotatably abut against the second sleeve 12212. The limiting opening 12211 restricts the range of rotation of the connecting rod 31, and the expansion opening 12213 provides an expansion space for the rotation of the connecting rod 31, thereby limiting the direction and range of rotation of the connecting rod 31, so that the connecting rod 31 can rotate in the defined direction and range. In these embodiments, the first opening 12122 of the first component 121 and the second opening 12212 of the second component 122 define a receiving groove for receiving the spherical protrusion 3131.

[0155] See Figure 18 and Figure 19 , Figure 18 This is a schematic diagram of an embodiment of the valve structure of this application, in which the driving part extends along a first direction and the linkage component closes the flow channel; Figure 19This is a schematic diagram of an embodiment of the valve structure of this application where the driving part extends along a first direction and the linkage component opens relative to the flow channel. In some embodiments, the driving part 211 of the driving member 21 of the driving assembly 20 may also extend along the first direction D1, that is, the driving part 211 has a 90-degree angle with the second direction D2. In these embodiments, the axial extension direction of the second end 312 of the connecting rod 31 does not pass through the center of the first end 311. Therefore, the driving assembly 20, which is displaced along the second direction D2, can also drive the connecting rod 31 in the driving part 211 to swing to open and close the flow channel P.

[0156] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the claims of the present invention.
