Description

Technical Field

[0001] This application relates to the field of ventilation device technology, and more specifically, to a multi-position flip valve and an inflation product. Background Technology

[0002] Inflatable products are suitable for many everyday situations due to their lightweight and ease of use. Among them, self-inflating products made with resilient materials (such as foam), like self-inflating mattresses, are increasingly popular because they require no inflation and offer greater convenience. However, when deflating self-inflating products, they are prone to back-inflation, making them difficult to store.

[0003] The problem of self-inflating products easily expanding due to backflow during storage can usually be improved by setting a reversible valve core. However, with current reversible valve cores, it is difficult for users to accurately control the valve core to a certain state and maintain it in order to achieve rapid air intake / exhaust and better one-way sealing. Utility Model Content

[0004] The purpose of this application is to provide a multi-stage flip valve and an inflation product that can accurately control the valve core to a certain state and maintain it.

[0005] In a first aspect, embodiments of this application provide a multi-position flip-type valve, the valve comprising: a valve seat and a valve core, the valve seat having a fluid passage; the valve core comprising a support plate and a one-way diaphragm, the support plate having a through hole, the one-way diaphragm being mounted on the support plate and covering the through hole, the support plate being flip-mounted within the fluid passage to achieve opening or one-way closing of the fluid passage; at least two sets of limiting components are provided between the valve core and the valve seat, the limiting components comprising a first limiting component and a second limiting component, the first limiting component being configured to limit the valve core when maintaining a large opening state of the fluid passage, and the second limiting component being configured to limit the valve core when maintaining a one-way closed state of the fluid passage.

[0006] In the implementation of this application, by setting a first limiting component between the valve core and the valve seat, the user can easily and accurately control the valve core to a state with a large opening in the fluid passage during the valve core flipping process, and maintain this state, thereby achieving rapid air intake / exhaust; at the same time, by setting a second limiting component between the valve core and the valve seat, the user can easily and accurately control the valve core to a one-way closed (one-way in or one-way out) state during the valve core flipping process, and maintain this state, thereby achieving a better one-way sealing effect.

[0007] As an optional implementation, each set of limiting components includes two mutually cooperating limiting members, namely a protrusion and a recess.

[0008] In the above implementation process, by using protruding and recessed parts to form a limiting component, the valve core will be stuck when it flips to the limiting position, so that the user can feel that the valve core has reached the limiting position.

[0009] As an optional implementation, one of the two limiting members is located on the inner wall of the valve seat. The limiting member has a smooth arc section located on the flipping path of the support plate to facilitate the flipping of the support plate.

[0010] In the above implementation process, by setting a smooth arc surface segment on the limiting component, it is possible to limit the valve core while reducing the impact on the valve core's rotation.

[0011] As an alternative implementation, at least one of the two limiting members can deform.

[0012] In the above implementation process, by enabling at least one of the two limiting members to deform, the effect on valve core rotation can be reduced while limiting the valve core.

[0013] As an optional implementation, the valve core includes two actuating members, which are respectively disposed on two surfaces of the support plate. Each actuating member includes a connecting part and a actuating part. One end of the connecting part is connected to the support plate, and the connection position between the connecting part and the support plate is located at the edge of the support plate. The other end of the actuating part is connected to the connecting part, and the end of the actuating part away from the connecting part extends toward the center of the fluid channel. The first limiting component and the second limiting component are both disposed between the actuating part and the valve seat.

[0014] In the above implementation process, by setting actuating elements on both surfaces of the support plate, and setting a certain angle between the connecting part and the actuating part, the entire actuating element is shaped like a "┎" handle, allowing the user to better actuate the valve core by touching the actuating part. At the same time, placing the limiting component between the actuating part and the valve seat can reduce the mutual influence between the limiting component and other valve components, and can provide a prerequisite for the valve core to achieve universal rotation while simultaneously achieving limiting.

[0015] As an optional implementation, the connecting part includes a first connecting part and a second connecting part, which are respectively connected to the edge of the support plate, and the actuating part is connected to the first connecting part and the second connecting part respectively. In the above implementation, by setting two connecting parts, the entire protrusion is made to resemble a "┎┐" shaped handle, which improves the strength of the actuating part and thus increases the service life of the valve. In addition, this structure of the actuating part also facilitates the setting of a limiting member in the middle of the actuating part, so as to cooperate with the valve seat to achieve a limiting function.

[0016] As an optional implementation, the actuating part is provided with a limiting member a, and the valve seat is provided with limiting members A and B. Limiting member A is located on the side wall of the fluid channel, and limiting members a and B cooperate to form a first limiting assembly. Limiting member B is located on the central axis of the fluid channel, and limiting members a and B cooperate to form a second limiting assembly. Alternatively, the valve seat is provided with limiting member A, which is located on the side wall of the fluid channel; the valve core is provided with limiting members a and b. Limiting member a is located on the actuating part, and limiting members a and B cooperate to form a first limiting assembly. Limiting member b is located on the side wall of the support plate, and limiting member b cooperates with limiting member A to form a second limiting assembly.

[0017] In the above implementation process, a common limiting element can be used at the limiting positions of the first limiting component and the second limiting component. The common limiting element can be set at the side wall of the fluid passage of the valve seat or at the actuating part of the valve core, which can reduce the structural complexity of the entire valve and make it easier to achieve limiting at different positions.

[0018] As an optional implementation, the limiting member a is in the shape of a protrusion; the limiting member A is in the shape of a concave ring, and the limiting member A is arranged around the side wall of the fluid channel.

[0019] In the above implementation process, by controlling the setting position and shape of the limiting component, the valve core can achieve the limiting effect while rotating in all directions.

[0020] As an optional implementation, the limiting member a is concave, the limiting member A is convex, and the limiting member A is disposed on the side wall of the fluid channel.

[0021] In the above implementation process, by controlling the shape of the limiting member a to be concave, the interference between the limiting member on the valve core and the fluid passage sidewall of the valve seat during the valve core flipping process can be reduced, making it easier for the valve core to flip.

[0022] As an optional implementation, both the first limiting component and the second limiting component are disposed between the side wall of the support plate and the valve seat.

[0023] As an optional implementation, the valve core includes a rotating shaft connected to the side wall of the support plate. The support plate is flipped and connected to the valve seat via the rotating shaft. The first limiting component and the second limiting component are both disposed between the rotating shaft and the valve seat.

[0024] As an optional implementation, the valve seat is provided with a connecting groove, which includes a first groove and a second groove that are connected. There is an included angle between the first groove and the second groove. The first groove extends to the end of the valve seat, and the rotating shaft can be installed from the end of the first groove and moved into the second groove.

[0025] In the above implementation process, the bracket plate and valve seat are flipped and connected by setting a rotating shaft and connecting groove, which makes it easy to install the valve core into the fluid channel of the valve seat and makes it less likely to fall out of the fluid channel.

[0026] As an alternative implementation, the valve core includes a rocker arm, a rotating shaft connected to the side wall of a support plate, the support plate being flipped and connected to a valve seat via the rotating shaft, and the rotating shaft extending out of the valve seat and connected to the rocker arm.

[0027] As an optional implementation, the valve core is provided with a limiting member a, the valve seat is provided with a limiting member A at position A, and the valve seat is provided with a limiting member B at position B. The limiting member a and the limiting member A cooperate to form a first limiting assembly, and the limiting member a and the limiting member B cooperate to form a second limiting assembly; or,

[0028] A limiting element a is provided at position a of the valve core, a limiting element b is provided at position b of the valve core, and a limiting element A is provided on the valve seat. The limiting element a and the limiting element A cooperate to form a first limiting assembly, and the limiting element b and the limiting element A cooperate to form a second limiting assembly.

[0029] In the above implementation process, a common limiting element can be used at the limiting positions of the first limiting component and the second limiting component. The common limiting element can be set at the valve seat or the valve core, which can reduce the structural complexity of the entire valve and make it easier to achieve limiting at different positions.

[0030] As an optional implementation, the distance between the unidirectional diaphragm and the support disk's flipping axis is no more than 5 mm.

[0031] In the above implementation process, by controlling the distance between the unidirectional diaphragm and the support plate rotation axis to be no more than 5mm, it is beneficial to maintain a larger fluid channel, which in turn facilitates rapid inflation and deflation.

[0032] As an optional implementation, a sealing structure is provided between the support plate and the valve seat.

[0033] In the above implementation process, by setting a sealing structure between the support plate and the valve seat, the valve core has a good sealing effect on the fluid channel, which can better maintain the use or storage state of the inflatable product.

[0034] As an optional implementation, the side wall of the support plate is provided with an annular groove, and the sealing structure includes a sealing ring. The sealing ring includes a sleeve portion and a first sealing thin plate ring and a second sealing thin plate ring connected to the sleeve portion. The sleeve portion is disposed in the annular groove, and the first sealing thin plate ring and the second sealing thin plate ring are spaced apart along the central axis of the sleeve portion. The first sealing thin plate ring and the second sealing thin plate ring are interference-fitted with the valve seat.

[0035] In the above implementation process, by setting the first sealing thin ring and the second sealing thin sheet at intervals along the central axis of the sleeve, the sealing position of the valve core to the fluid channel has a certain tolerance, and a good seal can still be maintained even when the central axis of the valve core does not coincide well with the central axis of the fluid channel.

[0036] As an optional implementation, the support plate includes a first sidewall and a third sidewall disposed opposite to each other, and a second sidewall and a fourth sidewall disposed opposite to each other, wherein the distance between the first sidewall and the third sidewall is greater than the distance between the second sidewall and the fourth sidewall.

[0037] In the above implementation process, by controlling the distance between the two side walls of the support plate to be unequal, the entire support plate is made into a relatively flat and long shape, which can reduce the radius of the flipping path and achieve a larger fluid channel even in a thinner case.

[0038] As an optional implementation, the valve also includes a blocking portion having a hollow area, which is mounted on the valve seat to cover the fluid passage.

[0039] In the above implementation process, by setting a blocking part to cover the fluid channel, foreign objects can be prevented from entering the valve core and affecting the sealing effect of the valve core.

[0040] As an optional implementation, the support plate is provided with multiple through holes, which are circumferentially distributed around the central axis of the support plate; the center of the unidirectional diaphragm is fixedly connected to the center of the support plate.

[0041] As an optional implementation, a connecting rod is provided at the center of the unidirectional diaphragm, and the connecting rod is perpendicular to the unidirectional diaphragm; a locking hole for locking the connecting rod is provided at the center of the support plate.

[0042] As an optional implementation, the through holes are fan-shaped, with the center of the fan shape close to the central axis of the support disk; each through hole has a stop on its arc-shaped edge, which is used to block the unidirectional diaphragm.

[0043] As an alternative implementation, the valve cover and valve seat are connected by a connecting strip.

[0044] In the above implementation process, the connection belt can reduce the probability of the valve cover being lost by the user during use.

[0045] Secondly, embodiments of this application provide an inflatable product, which includes a body and a valve provided in the first aspect, which is installed on the body, with the outer side of the valve seat connected to the body. Attached Figure Description

Detailed Implementation

[0064] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0065] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0066] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0067] Self-inflating products are prone to backflow and expansion during deflation, making them difficult to deflate. This issue can usually be mitigated by incorporating a reversible valve core. However, current reversible valve cores make it difficult for users to accurately control and maintain a specific state (e.g., maximum fluid channel opening or one-way sealing) to achieve rapid air intake / exhaust and a good one-way seal.

[0068] Figure 1 and Figure 2 This is a schematic diagram of the valve structure provided in an embodiment of this application. Figure 3 This is an exploded view of the valve provided in an embodiment of this application. Figures 4 to 6 For a structural schematic diagram of the valve core and valve seat provided in the embodiments of this application, please refer to [link / reference]. Figures 1 to 6 This application provides a multi-position flip-type valve. The valve 1 includes a valve seat 11 and a valve core 12. The valve seat 11 is provided with a fluid channel 111. The valve core 12 includes a support plate 121 and a one-way diaphragm 122. The support plate 121 is provided with a through hole 1211. The one-way diaphragm 122 is installed on the support plate 121 and covers the through hole 1211. The support plate 121 is flip-mounted in the fluid channel 111 to realize the opening or one-way closing of the fluid channel 111. At least two sets of limiting components 13 are provided between the valve core 12 and the valve seat 11. The limiting components 13 include a first limiting component 13a and a second limiting component 13b. The first limiting component 13a is configured to limit the valve core 12 when maintaining a large opening state of the fluid channel 111. The second limiting component 13b is configured to limit the valve core 12 when maintaining a one-way closed state of the fluid channel 111.

[0069] The valve seat 11 can have various shapes, such as a cube, cuboid, or cylinder. The cross-section of the fluid channel 111 inside can be square, elliptical, or circular, but is preferably circular.

[0070] The valve seat 11 can be made of various materials, such as metal materials like aluminum alloy, copper alloy, or stainless steel, or non-metallic materials like plastic.

[0071] Each set of limiting components 13 (first limiting component 13a and second limiting component 13b) is composed of two cooperating limiting members 131, which can be a protrusion 131a and a recess 131b. By using the protrusion 131a and the recess 131b to form the limiting component 13, the valve core 12 will be stuck when it flips to the limiting position, thus allowing the user to sense that the valve core 12 has reached the limiting position. The protrusion 131a can be a protrusion, a protruding ring, etc., and the corresponding recess 131b can be a concave point, a concave ring, etc.

[0072] The first limiting component 13a and the second limiting component 13b may share a portion of the limiting element 131. For example, please refer to [link to relevant documentation]. Figures 4 to 6 In some embodiments, the valve core 12 is provided with a limiting member a1311, the valve seat 11 is provided with a limiting member A1313 at position A, and the valve seat 11 is provided with a limiting member B1314 at position B. The limiting members a1311 and A1313 cooperate to form a first limiting component 13a, and the limiting members a1311 and B1314 cooperate to form a second limiting component 13b. In other embodiments, the valve core 12 is provided with a limiting member a1311 at position a, a limiting member b1312 at position b, and the valve seat 11 is provided with a limiting member A1313. The limiting members a1311 and A1313 cooperate to form a first limiting component 13a, and the limiting members b1312 and A1313 cooperate to form a second limiting component 13b. The first and second limiting components can share a single limiting element. This shared limiting element can be located at the valve seat or the valve core, which reduces the overall structural complexity of the valve and makes it easier to achieve limiting at different positions.

[0073] The first limiting component 13a and the second limiting component 13b may not share the limiting member 131. For example, in some embodiments, a limiting member a1311 is provided at position a of valve core 12, a limiting member b1312 is provided at position b of valve core 12, a limiting member A1313 is provided at position A of valve seat 11, and a limiting member B1314 is provided at position B of valve seat 11. The limiting members a1311 and A1313 cooperate to form the first limiting component 13a, and the limiting members b1312 and B1314 cooperate to form the second limiting component 13b.

[0074] The large opening state of the fluid passage 111 refers to the state in which the central axis of the valve core 12 and the central axis of the fluid passage 111 are perpendicular to each other. The perpendicularity at this point is not limited to 90°. Any angle around 90° (e.g., 80° to 100°) is within the protection scope of this application.

[0075] The one-way closed state of the fluid channel 111 refers to the state in which the central axis of the valve core 12 and the central axis of the fluid channel 111 coincide. Furthermore, the one-way closed state includes a one-way inlet state and a one-way outlet state. In the one-way inlet state, the one-way diaphragm 122 is closer to the inflatable product 2 relative to the support plate 121; in the one-way outlet state, the one-way diaphragm 122 is farther away from the inflatable product 2 relative to the support plate 121.

[0076] The structure of the support plate 121 matches the cross-sectional shape of the fluid channel 111 of the valve seat 11. The structure of the support plate 121 can be of various forms, such as circular, square or elliptical plate structure. Preferably, the shape of the support plate 121 is circular, which is consistent with the cross-sectional shape of the channel.

[0077] The support plate 121 can be made of various materials, such as metal materials like aluminum alloy, copper alloy, or stainless steel, or non-metallic materials like plastic.

[0078] The support plate 121 may include an annular portion, a fixed portion, and multiple support connecting rods. One end of each support connecting rod is sequentially and spaced around the fixed portion, and the other end of each support connecting rod is connected to the annular portion. In this way, the fixed portion is located inside the annular portion, and the annular portion, the fixed portion, and two adjacent support connecting rods form a through hole 1211.

[0079] The valve seat 11 and the support plate 121 can be connected in various ways. For example, the support plate 121 and the valve seat 11 can be connected and rotated by a pin. Of course, they can also be connected by a shaft, or by a connection method in which a cylindrical protrusion and a cylindrical groove cooperate, or by the sealing ring 151 in the following embodiment, etc., as long as the support plate 121 can be flipped relative to the valve seat 11.

[0080] The connection between the one-way diaphragm 122 and the support plate 121 can be achieved in various ways, such as bonding or snap-fitting. The one-way diaphragm 122 can also be connected to the support plate 121 via a connecting rod 1221. The connecting rod 1221 can be located at any position on the one-way diaphragm 122; for example, it can be located near the edge of the one-way diaphragm 122 or at its center. When located at the center of the one-way diaphragm 122, the connecting rod 1221 is perpendicular to the one-way diaphragm 122. A locking hole for engaging the connecting rod 1221 is provided at the center of the support plate 121, through which the connecting rod 1221 passes to connect the one-way diaphragm 122 and the support plate 121. The one-way diaphragm 122 can be made of various materials; preferably, it is made of an elastic material. In this way, the one-way diaphragm 122 can return to its original shape without the action of external force, and the through hole 1211 on the sealing support plate 121 achieves one-way sealing. One-way sealing means that fluid can only flow from one side of the through hole 1211 to the other side, and vice versa.

[0081] In some embodiments, one of the two limiting members 131 is located on the inner wall of the valve seat 11. The limiting member 131 has a smooth arc surface segment 131c, which is located on the flipping path of the support plate 121 to facilitate the flipping of the support plate 121. For example, when the limiting member 131 is arranged in a concave annular shape on the inner wall of the fluid channel 111, the smooth arc surface segment 131c is the two side walls of the concave annular limiting member 131; or, when the limiting member 131 is arranged in a concave dot shape on the central axis of the fluid channel 111, the smooth arc surface segment 131c is arranged on the side walls around the concave dot-shaped limiting member 131; or, when the limiting member 131 is arranged in an annular shape on the inner wall of the fluid channel 111, the smooth arc surface segment 131c is the two side walls of the concave annular limiting member 131; or, when the limiting member 131 is arranged in a convex dot shape on the central axis of the fluid channel 111, the smooth arc surface segment 131c is arranged on the side walls around the concave dot-shaped limiting member 131. By providing the smooth arc surface segment 131c on the limiting member 131, the effect on the rotation of the valve core 12 can be reduced while achieving the limiting of the valve core 12.

[0082] In other embodiments, this application may omit the smooth arc segment 131c and instead use other methods to reduce the influence of the limiting member 131 on the valve core 12's rotation. For example, the limiting member 131 may be made of a deformable material.

[0083] In some embodiments, at least one of the two limiting members 131 is deformable. The deformability can be achieved by the limiting member 131 having a weak point or by the limiting member 131 being made of a deformable material. By enabling at least one of the two limiting members 131 to deform, the effect on the valve core 12's rotation can be reduced while simultaneously limiting its movement. For example, the valve seat may be made of soft rubber to allow deformation of the limiting members on the valve seat.

[0084] Please continue reading. Figures 1 to 6 In some embodiments, at least one surface of the support plate 121 is provided with a toggle member 123, and a first limiting component 13a and a second limiting component 13b are disposed between the toggle member 123 and the valve seat 11.

[0085] The toggle element 123 can be in the shape of a handle (e.g., Figure 7 , Figure 8 , Figure 9 (as shown), ring-shaped, etc.

[0086] The connection position of the toggle 123 with the bracket plate 121 can be located at any position on the bracket plate 121. For example, the connection position can be located near the edge of the bracket plate 121 or at the center of the bracket plate 121.

[0087] The toggle element 123 can be made of various materials, such as metal materials like aluminum alloy, copper alloy, or stainless steel, or non-metallic materials like plastic.

[0088] The actuating element 123 and the support plate 121 can be integrally formed. The actuating element 123 and the support plate 121 can also be combined by a detachable connection, such as snap-fit, pin connection, or adhesive bonding. The actuating element 123 and the support plate 121 can also be combined by a fixed connection, such as welding, hot melt connection, or ultrasonic welding.

[0089] By placing the limiting component 13 between the actuating part 1232 and the valve seat 11, the mutual influence between the limiting component 131 and other components of the valve 1 can be reduced, and the premise for the valve core 12 to achieve universal rotation while achieving the limiting is provided.

[0090] It should be noted that universal rotation means that the valve core does not have a fixed rotation axis and can be rotated in any direction.

[0091] Figure 7 and Figure 9 For a schematic diagram of the valve core 12 provided in the embodiments of this application, please refer to [link / reference]. Figure 7 and Figure 9In some embodiments, the actuating element 123 includes a connecting portion 1231 and an actuating portion 1232. One end of the connecting portion 1231 is connected to the support plate 121, and the other end of the actuating portion 1232 is connected to the connecting portion 1231. The connection position between the connecting portion 1231 and the support plate 121 is located at the edge of the support plate 121. By connecting the connecting portion 1231 to the support plate 121 and positioning the actuating portion 1232 away from the support plate 121, it is easier for the user to contact the actuating portion 1232 near the valve port, transmitting the actuation to the support plate 121 and achieving the rotation of the entire valve core 12. Furthermore, by positioning the connection position between the connecting portion 1231 and the support plate 121 at the edge of the support plate 121, the one-way diaphragm 122 can be more easily avoided, reducing the probability of interference between the two and thus reducing the structural complexity of the entire valve core 12.

[0092] Please continue reading. Figure 7 and Figure 8 In some embodiments, the actuating part 1232 extends towards the center of the fluid channel 111 from the end away from the connecting part 1231, and the first limiting component 13a and the second limiting component 13b are both disposed between the actuating part 1232 and the valve seat 11. By providing the actuating element 123 on both surfaces of the support plate 121, and setting a certain angle between the connecting part 1231 and the actuating part 1232, the entire actuating element 123 is shaped like a "┎" handle, allowing the user to better actuate the valve core 12 by touching the actuating part 1232. At the same time, placing the limiting component 13 between the actuating part 1232 and the valve seat 11 can reduce the mutual influence between the limiting component 131 and other components of the valve 1, and can provide a premise for the valve core 12 to achieve universal rotation while simultaneously achieving limiting. For example, the actuating part 1232 and the connecting part 1231 can be integrally formed as an arc segment (e.g., Figure 7 As shown), the actuating part 1232 and the connecting part 1231 can be two straight sections connected together (e.g., Figure 8 As shown, when the actuating part 1232 and the connecting part 1231 are two straight segments connected, the included angle α between the connecting part 1231 and the actuating part 1232 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc., or any value within the range of 90°≤α<180°. When the actuating part 1232 and the connecting part 1231 are integrally formed by an arc segment, the included angle between them is the angle between their center lines.

[0093] Please continue reading. Figure 9In some embodiments, the connecting portion 1231 includes a first connecting portion 1231a and a second connecting portion 1231b, which are respectively connected to the edge of the support plate 121. The actuating portion 1232 is connected to the first connecting portion 1231a and the second connecting portion 1231b. By providing two connecting portions 1231, the entire actuating member 123 is shaped like a "┎┐" handle, which improves the strength of the actuating member 123 and thus increases the service life of the valve 1. In addition, this structure of the actuating member also facilitates the setting of a limiting member in the middle of the actuating portion, so as to cooperate with the valve seat to achieve a limiting function. Preferably, the connection positions of the first connecting portion 1231a and the second connecting portion 1231b with the support plate 121 are located on the same diameter line of the support plate 121. It should be noted that the actuating portion 1232 can be continuous or discontinuous.

[0094] Specifically, the protrusion 131a of the first limiting component 13a can be provided on the actuating member 123 (e.g., the actuating part 1232) or the valve seat 11, and the corresponding recess 131b of the first limiting component 13a can be provided on the valve seat 11 or the actuating member 123 (e.g., the actuating part 1232). The protrusion 131a can be annular, dot-shaped, etc., and the corresponding recess 131b can be annular, dot-shaped, etc. Further explanation will be given using the example of the protrusion 131a being provided on the actuating member 123 and the recess 131b being provided on the valve seat 11. Please refer to the following text. Figure 4 The protrusion 131a is arranged in a ring around the actuating member 123 along a line perpendicular to the central axis of the support plate 121, and the recess 131b is distributed on the valve seat 11 with a plane perpendicular to the central axis of the fluid channel 111. As you can understand, please continue reading... Figure 5 The protrusion 131a and the recess 131b can be interchanged to achieve the same effect. Similarly, the protrusion 131a of the second limiting component 13b can be located on the actuating component 123 or the valve seat 11, and the corresponding recess 131b of the second limiting component 13b can be located on the valve seat 11 or the actuating component 123. The shapes of the protrusion 131a and the recess 131b can be referenced to the setting of the first limiting component 13a. Further explanation will be provided using the example of the protrusion 131a located on the actuating component 123 and the recess 131b located on the valve seat 11. Please refer to the following text. Figure 4 The protrusion 131a is arranged around the actuating member 123 with the axis of a line perpendicular to the central axis of the support plate 121, and the recess 131b is distributed on the valve seat 11 with the plane parallel to or coincident with the central axis of the fluid channel 111.

[0095] The protrusions 131a of the first limiting component 13a and the second limiting component 13b are typically located on the same component (e.g., the actuating component 123), and the first limiting component 13a and the second limiting component 13b can share either the protrusion 131a or the recess 131b (for example, when the protrusion 131a is located on the actuating component 123, the first limiting component 13a and the second limiting component 13b share the protrusion 131a; when the recess 131b is located on the actuating component 123, the first limiting component 13a and the second limiting component 13b share the recess 131b). By having the first limiting component 13a and the second limiting component 13b share a single protrusion 131a, the structural complexity of the entire valve 1 can be reduced.

[0096] For example, in some embodiments, please continue to refer to Figure 4 and Figure 5 The actuating part 1232 is provided with a limiting member a1311, and the valve seat 11 is provided with limiting members A1313 and B1314. Limiting member A1313 is located on the side wall of the fluid channel 111. Limiting members a1311 and B1313 cooperate to form a first limiting assembly 13a. Limiting member B1314 is located on the central axis of the fluid channel 111. Limiting members a1311 and B1314 cooperate to form a second limiting assembly 13b. At the limiting points of the first and second limiting assemblies, a single limiting member can be shared. The shared limiting member is located at the actuating part of the valve core, which can reduce the structural complexity of the entire valve and make it easier to achieve limiting at different positions.

[0097] To achieve a limiting effect while the valve core 12 can rotate in all directions, please refer to further details. Figure 4 The actuating part 1232 is provided with a limiting member a1311, which is in the shape of a protruding dot. The valve seat 11 is provided with a limiting member A1313 and a limiting member B1314. The limiting member A1313 is in the shape of a concave ring and is arranged around the side wall of the fluid channel 111. The limiting members a1311 and B1313 cooperate to form a first limiting component 13a. The limiting member B1314 is in the shape of a concave dot and is located on the central axis of the fluid channel 111. The limiting members a1311 and B1314 cooperate to form a second limiting component 13b. By controlling the setting position and shape of the limiting member 131, the valve core 12 can achieve a limiting effect while rotating in all directions.

[0098] For example, in some other embodiments, the valve seat 11 is provided with a limiting member A1313, which is located on the side wall of the fluid passage 111; the valve core 12 is provided with a limiting member a1311 and a limiting member b1312. The limiting member a1311 is located on the actuating part 1232. The limiting members a1311 and A1313 cooperate to form a first limiting assembly 13a, and the limiting member b1312 is located on the side wall of the support plate 121. The limiting members b1312 and A1313 cooperate to form a second limiting assembly 13b. A single limiting member can be shared at the limiting points of the first and second limiting assemblies. The shared limiting member located on the side wall of the fluid passage of the valve seat reduces the overall structural complexity of the valve and makes it easier to achieve limiting at different positions.

[0099] To achieve a limiting effect while the valve core 12 can rotate in all directions, the valve seat 11 is further provided with a limiting member A1313, which is a concave ring and is wrapped around the side wall of the fluid channel 111. The valve core 12 is provided with limiting members a1311 and b1312, both of which are protrusions 131a. Limiting member a1311 is located on the actuating part 1232, and the limiting members a1311 and b1313 cooperate to form a first limiting component 13a. Limiting member b1312 is located on the side wall of the support plate 121, and the limiting members b1312 and a1313 cooperate to form a second limiting component 13b. By controlling the setting position and shape of the limiting members 131, the valve core 12 can achieve a limiting effect while rotating in all directions.

[0100] To reduce interference between the limiting member 131 and the fluid passage sidewall of the valve seat, in some embodiments, the limiting member a is concave and the limiting member A is convex, with the limiting member A located on the sidewall of the fluid passage. By controlling the shape of the limiting member a to be concave, interference between the limiting member on the valve core and the fluid passage sidewall of the valve seat during valve core rotation can be reduced, facilitating valve core rotation.

[0101] In some embodiments, the actuating element 123 and the support plate 121 are integrally formed. The integrally formed actuating element 123 and support plate 121 have better structural strength, which is beneficial to the service life of the entire valve core 12.

[0102] Figure 10 For a schematic diagram of the valve core 12 provided in the embodiments of this application, please refer to [link / reference]. Figure 10In some embodiments, the actuating element 123 and the support plate 121 are detachably connected. The detachable connection can be achieved through snap-fit, pin connection, adhesive bonding, etc. By using a detachable connection to connect the actuating element 123 and the support plate 121, the one-way diaphragm 122 can be installed on the support plate 121 first, and then the actuating element 123 can be installed, avoiding the problem of the one-way diaphragm 122 being difficult to install due to obstruction by the actuating element 123.

[0103] It is understandable that by first installing the one-way diaphragm 122 onto the support plate 121, and then connecting the actuating member 123 to the support plate 121, the problem of difficulty in installing the one-way diaphragm 122 due to obstruction by the actuating member 123 can be avoided. Therefore, in other embodiments, the one-way diaphragm 122 can also be installed onto the support plate 121 first, and then the actuating member 123 can be connected to the support plate 121 by a fixed connection. For example, the one-way diaphragm 122 can be installed onto the support plate 121 first, and then the actuating member 123 can be welded to the support plate 121 by ultrasonic welding.

[0104] Figure 11 For a schematic diagram of the valve core 12 provided in the embodiments of this application, please refer to [link / reference]. Figure 11 In some embodiments, the actuating member 123 includes a connecting portion 1231 and an actuating portion 1232. The connecting portion 1231 includes a connecting ring piece 1231c and a connecting block 1231d connected to the connecting ring piece 1231c. The connecting ring piece 1231c is fixedly connected to the support disk 121, and the actuating portion 1232 is connected to the connecting block 1231d. Furthermore, using the connecting ring piece 1231c to fixarily connect to the support disk 121 increases the connection area between the actuating member 123 and the support disk 121, thereby enhancing the connection strength between the actuating member 123 and the support disk 121.

[0105] Optionally, the connecting ring 1231c and the connecting block 1231d are integrally formed. The unidirectional diaphragm 122 is first installed on the support plate 121, and then the connecting ring 1231c and the support plate 121 are connected (e.g., by welding or bonding). This avoids the problem of the unidirectional diaphragm 122 being difficult to install due to the obstruction of the actuating part 1232.

[0106] Optionally, the actuating part 1232 can be a bent strip, with one end connected to a connecting block 1231d on the connecting ring 1231c and the other end connected to another connecting block 1231d on the connecting ring 1231c. The two connecting blocks 1231d are arranged symmetrically on both sides of the connecting ring 1231c, forming a structure in which the connecting block 1231d, the actuating part 1232 and the other connecting block 1231d are connected in sequence, forming a handle shape similar to "┎┐".

[0107] Figure 12For a schematic diagram of the valve core 12 provided in the embodiments of this application, please refer to [link / reference]. Figure 12 In some embodiments, the support plate 121 includes a first support plate 121a and a second support plate 121b, both having through holes 1211. The first support plate 121a and the second support plate 121b are detachably connected, and a one-way diaphragm 122 is disposed between the first support plate 121a and the second support plate 121b. The detachable connection can be achieved through snap-fit ​​or fastening. By using a support plate 121 composed of a detachably connected first support plate 121a and the second support plate 121b, and installing the one-way diaphragm 122 between the first support plate 121a and the second support plate 121b, the problem of difficulty in installing the one-way diaphragm 122 due to obstruction by the actuating member 123 can be avoided.

[0108] Specifically, after obtaining the separate first support disk 121a and second support disk 121b, the unidirectional diaphragm 122 is first placed on the first support disk 121a, and then the second support disk 121b is connected to the first support disk 121a. Alternatively, the unidirectional diaphragm 122 can be placed on the second support disk 121b first, and then the first support disk 121a and the second support disk 121b can be connected.

[0109] Optionally, a toggle member 123 can be installed on the first support plate 121a, with one end of the toggle member 123 connected to the side of the first support plate 121a away from the second support plate 121b, and the other end extending away from the first support plate 121a; or a toggle member 123 can be installed on both the first support plate 121a and the second support plate 121b, with one end of the toggle member 123 connected to the side of the first support plate 121a away from the second support plate 121b, and the other end extending away from the first support plate 121a, and one end of the other toggle member 123 connected to the side of the second support plate 121b away from the first support plate 121a, and the other end extending away from the second support plate 121b.

[0110] It should be noted that when the actuating element 123 is in the shape of a handle, during use, depending on the usage method, for example, when moving along the direction of the actuating element 123, the actuating element 123 can be regarded as a dial. In this case, the shape and position of the limiting element 131 of the limiting structure can be adjusted according to the actual situation, which will not be elaborated here.

[0111] In some embodiments, the first limiting component 13a and the second limiting component 13b are disposed between the side wall of the support plate 121 and the valve seat 11.

[0112] Specifically, the protrusion 131a of the first limiting component 13a can be disposed on the support plate 121 or the valve seat 11, and the corresponding recess 131b of the first limiting component 13a can be disposed on the valve seat 11 or the support plate 121. The protrusion 131a can be annular, dot-shaped, etc., and the corresponding recess 131b can be annular, dot-shaped, etc. Taking the protrusion 131a disposed on the support plate 121 and the recess 131b disposed on the valve seat 11 as an example, the protrusion 131a is arranged around the central axis of the support plate 121 on the side wall of the support plate 121, and the plane of the recess 131b distributed on the valve seat 11 is parallel to or coincides with the central axis of the fluid channel 111. It can be understood that the positions of the protrusion 131a and the recess 131b can be interchanged to achieve the same effect. Similarly, the protrusion 131a of the second limiting component 13b can be provided on the support plate 121 or the valve seat 11, and the corresponding recess 131b of the second limiting component 13b can be provided on the valve seat 11 or the support plate 121. The shapes of the protrusion 131a and the recess 131b can be referred to the setting of the first limiting component 13a. Taking the protrusion 131a provided on the support plate 121 and the recess 131b provided on the valve seat 11 as an example, the protrusion 131a is arranged around the central axis of the support plate 121 on the side wall of the support plate 121, and the plane of the recess 131b distributed on the valve seat 11 is perpendicular to the central axis of the fluid channel 111. The protrusions 131a of the first limiting component 13a and the second limiting component 13b are usually provided on the same component (e.g., the support plate 121), and the first limiting component 13a and the second limiting component 13b can share the protrusions 131a or the recesses 131b (for example, when the protrusions 131a are provided on the support plate 121, the first limiting component 13a and the second limiting component 13b share the protrusions 131a; when the recesses 131b are provided on the support plate 121, the first limiting component 13a and the second limiting component 13b share the recesses 131b).

[0113] Please continue reading. Figure 6 In some embodiments, the support plate 121 is flipped and connected to the valve seat 11 via a rotating shaft 124; the rotating shaft 124 is fixedly connected to the support plate 121, and a first limiting component 13a is disposed between the rotating shaft 124 and the valve seat 11; or, the rotating shaft 124 is fixedly connected to the valve seat 11, and the first limiting component 13a is disposed between the rotating shaft 124 and the support plate 121; the support plate 121 is flipped and connected to the valve seat 11 via a rotating shaft 124; the position of the rotating shaft 124 can be that the rotating shaft 124 is fixedly connected to the support plate 121, and a second limiting component 13b is disposed between the rotating shaft 124 and the valve seat 11; or, the position of the rotating shaft 124 can also be that the rotating shaft 124 is fixedly connected to the valve seat 11, and the second limiting component 13b is disposed between the rotating shaft 124 and the support plate 121.

[0114] Specifically, the protrusion 131a of the first limiting component 13a can be located in the rotating shaft 124 or a corresponding mating rotating hole, and the recess 131b of the corresponding first limiting component 13a can be located in the rotating hole or the rotating shaft 124. The protrusion 131a can be linear, dot-shaped, etc., and the corresponding recess 131b can be linear, dot-shaped, etc. Taking the example of the protrusion 131a being located in the rotating shaft 124 and the recess 131b being located in the rotating hole, the protrusion 131a is arranged parallel to the central axis of the rotating shaft 124, and the radial plane of the rotating shaft 124 where it is located is perpendicular to the central axis of the support disk 121. The plane of the recess 131b distributed in the rotating hole is parallel to or coincides with the central axis of the fluid channel 111. It can be understood that the protrusion 131a and the recess 131b can be interchanged to achieve the same effect. Similarly, the protrusion 131a of the second limiting component 13b can be disposed in the rotating shaft 124 or the corresponding rotating hole, and the recess 131b of the corresponding second limiting component 13b can be disposed in the rotating hole or the rotating shaft 124. The shapes of the protrusion 131a and the recess 131b can be referred to the setting of the first limiting component 13a. Taking the protrusion 131a disposed in the rotating shaft 124 and the recess 131b disposed in the rotating hole as an example, the protrusion 131a is arranged parallel to the central axis of the rotating shaft 124, and the radial plane of the rotating shaft 124 where it is located is perpendicular to the central axis of the support plate 121. The plane in which the recess 131b is distributed in the rotating hole is perpendicular to the central axis of the fluid channel 111. The protrusions 131a of the first limiting component 13a and the second limiting component 13b are usually provided on the same component (e.g., the rotating shaft 124), and the first limiting component 13a and the second limiting component 13b can share the protrusions 131a or the recesses 131b (for example, when the protrusions 131a are provided on the rotating shaft 124, the first limiting component 13a and the second limiting component 13b share the protrusions 131a; when the recesses 131b are provided on the rotating shaft 124, the first limiting component 13a and the second limiting component 13b share the recesses 131b).

[0115] Figure 13 For a schematic diagram of the fit between the rotating shaft 124 and the connecting groove 112 provided in the embodiments of this application, please refer to... Figure 13In some embodiments, the support plate 121 is provided with a rotating shaft 124, and the valve seat 11 is provided with a connecting groove 112. The connecting groove 112 includes a first groove 112a and a second groove 112b that are connected. There is an included angle between the first groove 112a and the second groove 112b (for example, the first groove 112a and the second groove 112b can be "L" shaped). The first groove 112a extends to the end of the valve seat 11, and the rotating shaft 124 can be installed from the end of the first groove 112a and moved to the second groove 112b. By setting the rotating shaft 124 and the connecting groove 112 to realize the flip connection between the support plate 121 and the valve seat 11, it is easy to install the valve core 12 into the fluid channel 111 of the valve seat 11, and it is not easy for it to fall out of the fluid channel 111.

[0116] In some embodiments, the support plate 121 is provided with a rotating shaft 124, and the support plate 121 is flipped and connected to the valve seat 11 through the rotating shaft 124. The rotating shaft 124 extends out of the valve seat 11 to form a rocker arm, and a first limiting component 13a is disposed between the rocker arm and the valve seat 11. The support plate 121 is provided with a rotating shaft 124, and the support plate 121 is flipped and connected to the valve seat 11 through the rotating shaft 124. The valve core 12 also includes a rocker arm, the rotating shaft 124 extends out of the valve seat 11 and is connected to the rocker arm, and a second limiting component 13b is disposed between the rocker arm and the valve seat 11.

[0117] Specifically, the protrusion 131a of the first limiting component 13a can be located on the rocker arm or the valve seat 11, and the corresponding recess 131b of the first limiting component 13a can be located on the valve seat 11 or the rocker arm. The protrusion 131a can be linear, dot-shaped, etc., and the corresponding recess 131b can be linear, dot-shaped, etc. Taking the protrusion 131a located on the rocker arm and the recess 131b located on the valve seat 11 as an example, the protrusion 131a is perpendicular to the central axis of the support plate 121, and the recess 131b is parallel to or coincides with the central axis of the fluid channel 111. It can be understood that the protrusion 131a and the recess 131b can be interchanged to achieve the same effect. Similarly, the protrusion 131a of the second limiting component 13b can be provided on the rocker arm or the valve seat 11, and the corresponding recess 131b of the second limiting component 13b can be provided on the valve seat 11 or the rocker arm. The shapes of the protrusion 131a and the recess 131b can be referenced to the setting of the first limiting component 13a. Taking the protrusion 131a being provided on the rocker arm and the recess 131b being provided on the valve seat 11 as an example, the protrusion 131a is set perpendicular to the central axis of the support plate 121, and the recess 131b is set perpendicular to the central axis of the fluid channel 111. The protrusion 131a of the first limiting component 13a and the second limiting component 13b are usually provided on the same component (e.g., a rocker arm), and the first limiting component 13a and the second limiting component 13b can share the protrusion 131a or the recess 131b (for example, when the protrusion 131a is provided on the rocker arm, the first limiting component 13a and the second limiting component 13b share the protrusion 131a; when the recess 131b is provided on the rocker arm, the first limiting component 13a and the second limiting component 13b share the recess 131b).

[0118] In some embodiments, the distance between the rotation axes of the unidirectional diaphragm 122 and the support disk 121 is no greater than 5 mm. By controlling the distance between the rotation axes of the unidirectional diaphragm 122 and the support disk 121 to be no greater than 5 mm, it is beneficial to maintain a larger fluid channel 111, which in turn facilitates rapid inflation and deflation.

[0119] In some embodiments, a sealing structure 15 is provided between the support plate 121 and the valve seat 11. The sealing structure 15 may be provided on the support plate 121 or in the fluid passage 111 of the valve seat 11.

[0120] When the sealing structure 15 is disposed within the fluid channel 111 of the valve seat 11, the sealing structure 15 can be a sealing ring, which is fixedly connected to the fluid channel 111 of the valve seat 11. When disposed on the support plate 121, the sealing structure 15 can be a sealing ring 151, which is fitted onto the support plate 121. The sealing ring 151 is interference-fitted with the side wall of the fluid channel 111 to fill the gap between the support plate 121 and the side wall of the fluid channel 111, and allows the support plate 121 to rotate omnidirectionally relative to the valve seat 11. The cross-sectional shape of the sealing ring 151 can be various, such as circular, T-shaped, or square. The material of the sealing ring 151 can also be various, such as rubber or silicone, etc., which are elastic materials. When the user inflates or deflates the inflatable product 2, the interference fit between the sealing ring 151 and the fluid channel 111 allows the valve core 12 to rotate in multiple directions, thus facilitating user operation.

[0121] Figure 14 For a schematic diagram of the sealing structure 15 provided in the embodiments of this application, please refer to [link / reference]. Figure 14 In some embodiments, the sidewall of the support plate 121 is provided with an annular groove 1212, and the sealing structure 15 includes a sealing ring 151. The sealing ring 151 includes a sleeve portion 1511 and a first sealing thin ring 1512 and a second sealing thin ring 1513 connected to the sleeve portion 1511. The sleeve portion 1511 is disposed in the annular groove 1212. The first sealing thin ring 1512 and the second sealing thin ring 1513 are spaced apart along the central axis of the sleeve portion 1511 (i.e., the cross-sectional shape of the sealing ring 151 is "U" shaped). The first sealing thin ring 1512 and the second sealing thin ring are interference-fitted with the valve seat 11. By spaced apart the first sealing thin ring 1512 and the second sealing thin ring along the central axis of the sleeve portion 1511, the sealing position of the valve core 12 on the fluid channel 111 has a certain tolerance, and a good seal can still be maintained even when the central axis of the valve core 12 does not coincide well with the central axis of the fluid channel 111.

[0122] In some embodiments, valve 1 further includes a valve cover 14, which is detachably connected to valve seat 11. The valve cover 14 can be connected to valve seat 11 by snap-fit ​​or threaded connection to achieve sealing of fluid passage 111.

[0123] The valve cover 14 can have various structures. For example, the valve cover 14 includes a cover body 21, which is a hollow shell with one open end. An annular cover extends outward from the edge of the open end of the cover body 21, and the annular cover is perpendicular to the side wall of the cover body 21. This structure can save raw materials for the valve cover 14. In addition, on the outer side wall of the cover body 21, multiple annular protrusions or threads are provided along the circumferential direction of the outer side wall to improve the sealing between the valve cover 14 and the valve seat 11.

[0124] The valve cover 14 can be made of various materials, preferably plastic, rubber or silicone.

[0125] Figure 15 Please refer to the structural schematic diagram of the support plate 121 provided in the embodiment of this application. Figure 15 In some embodiments, the support disk 121 includes a first sidewall 1214 and a third sidewall 1216 disposed opposite to each other, and a second sidewall 1215 and a fourth sidewall 1217 disposed opposite to each other. The distance between the first sidewall 1214 and the third sidewall 1216 is greater than the distance between the second sidewall 1215 and the fourth sidewall 1217. For example, the support disk 121 can be racetrack-shaped, elliptical, etc. By controlling the distance between the opposite sidewalls of the support disk 121 to be unequal, the entire support disk 121 is made to have a relatively flat and elongated shape, thereby reducing the radius of the flipping path and enabling a larger fluid channel 111 to be achieved even with a thinner surface.

[0126] In some embodiments, the valve 1 further includes a blocking portion 16, which has a hollow area and is mounted on the valve seat 11 to cover the fluid passage 111. By providing the blocking portion 16 to cover the fluid passage 111, foreign objects can be prevented from entering the valve core 12 and affecting its sealing effect. For example, the blocking portion 16 can be a hollow shell with one open end, and the blocking portion 16 is hollow. The shape of the blocking portion 16 can be various, such as hemispherical, cylindrical, cubic, or cuboid, etc. Preferably, the blocking portion 16 is hemispherical, and the diameter of the blocking portion 16 is larger than the diameter of the passage. This prevents friction between the valve core 12 and the blocking portion 16 during the valve's rotation.

[0127] The blocking part 16 and the valve seat 11 can be a separate design or an integrated design.

[0128] Preferably, in order to prevent the valve core 12 from falling into the inflatable product 2 due to excessive force by the user, the end of the valve seat 11 with the blocking part 16 is placed inside the inflatable product 2, which can prevent the valve core 12 from falling off the valve seat 11 into the inflatable product 2.

[0129] In some embodiments, the support disk 121 is provided with a plurality of through holes 1211, which are circumferentially distributed around the central axis of the support disk 121; the central portion of the one-way diaphragm 122 is fixedly connected to the central portion of the support disk 121. The one-way diaphragm 122 has a connecting rod 1221 at its center, and the connecting rod 1221 is perpendicular to the one-way diaphragm 122; the support disk 121 has a locking hole at its center for engaging the connecting rod 1221. When gas enters the channel from the side of the support disk 121 away from the one-way diaphragm 122, the one-way diaphragm 122 moves or deforms away from the support disk 121 under the action of gas pressure, thereby opening the through holes 1211 on the support disk 121 and thus unblocking the channel. When the gas supply to the channel stops, the one-way diaphragm 122 can seal the through holes 1211 on the support disk 121 by its own elastic deformation and the gas pressure within the inflatable material.

[0130] Furthermore, the through-hole 1211 is fan-shaped, with the center of the fan close to the central axis of the support plate 121; each through-hole 1211 has a stop 1213 on its arc-shaped edge, which is used to block the unidirectional diaphragm 122. The stop 1213 can be integrated with the support plate 121, or it can be designed separately from the support plate 121, or the stop 1213 can be omitted.

[0131] In some embodiments, the valve cover 14 and the valve seat 11 are connected by a connecting strap. The connecting strap reduces the probability of the valve cover 14 being lost by the user during use.

[0132] The valve 1, by setting a first limiting component 13a between the valve core 12 and the valve seat 11, allows the user to easily and accurately adjust the valve core 12 to a state with a large opening in the fluid passage 111 during the valve core 12 flipping process, and maintain this state, thereby achieving rapid air intake / exhaust. At the same time, by setting a second limiting component 13b between the valve core 12 and the valve seat 11, the user can easily and accurately adjust the valve core 12 to a one-way closed (one-way entry or one-way discharge) state during the valve core 12 flipping process, and maintain this state, thereby achieving a better one-way sealing effect.

[0133] Based on the same inventive concept, this application also provides an inflatable product 2. Figure 16 For a structural schematic diagram of the inflatable product 2 provided in this application embodiment, please refer to [link / reference]. Figure 16 The inflatable product 2 includes a body 21 and a valve 1 as described above installed on the body 21, with the outer side of the valve seat 11 of the valve 1 connected to the body 21.

[0134] The inflatable product 2 is based on the valve 1 described above. The specific contents of the valve 1 can be referred to in the above embodiments. Since the inflatable product 2 adopts some or all of the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0135] Optionally, the inflatable product 2 can be an inflatable mattress, an inflatable foam mattress, an inflatable sofa, an inflatable pool, an inflatable toy, or an inflatable pillow, etc.

[0136] The entire working process of valve 1 in inflation and gas production is as follows: Taking gas as an example, during inflation, valve core 12 flips and is limited by the second limiting component to a position that only allows gas to enter the inflated product 2 (see [link]). Figure 1 (While inflating, keep valve cover 14 open), inflate the inflatable product 2 using an inflation tool. The gas will push the one-way diaphragm 122 into the inflated material, thus opening the channel. After inflation, the one-way diaphragm 122, due to the gas pressure inside the inflatable product 2 being greater than the external atmospheric pressure, presses against the support plate 121, sealing the through hole 1211. When rapid deflation is needed, flip the valve core 12 and keep it in place by the first limiting component, allowing the channel to open in a straight-through state. When the user needs to store the inflated material, the valve core 12 can be flipped and kept in place by the second limiting component, allowing only gas to flow out of the inflated material (see [reference]). Figure 2 (And keep the valve cover 14 open when venting) The gas pressure inside the inflatable product 2 is increased by squeezing until it is greater than the external atmospheric pressure, thereby opening the channel to vent and minimizing the volume of the inflatable. After squeezing stops, the gas pressure inside the inflatable product 2 is less than the external atmospheric pressure, causing the one-way diaphragm 122 to abut against the support plate 121, forming a state where air cannot enter.

[0137] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0138] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
