Description

[0001] This application claims priority to Chinese Patent Application No. 202422739573.8, filed on November 8, 2024, entitled "An Air Valve", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to the field of ventilation devices, and in particular to an air valve, an air valve assembly, and an inflation product. Background Technology

[0003] Existing products on the market include air mattresses and air valves used in air mattresses. As people's demands for quality of life increase, the demand for inflatable products, especially air mattresses and inflatable foam mattresses, is growing. To avoid the need for users to repeatedly re-inflate these products during use, an air valve with better sealing performance for air mattresses (such as TPU inflatable foam mattresses, i.e., air mattresses made of thermoplastic polyurethane (TPU) material) has emerged.

[0004] The main problem with the existing products is that although the existing air valve can seal the inflatable products and can be connected to an air pump to inflate the products, the sealing performance of the air valve is poor. Furthermore, when deflating the inflatable products, the gas will flow back into the inflatable products, resulting in the inability to completely expel the gas inside the inflatable mattress. This means that users need a large space to store the inflatable products when they are not in use. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor sealing performance in existing air valves. This invention provides an air valve, an air valve assembly, and an inflation product, which can achieve a stable sealing effect.

When the pressure of the gas (e.g., air) in the inflation chamber 13 reaches the required value, the inflatable body 100 is in an inflated state and maintains a preset shape. When the gas in the inflation chamber 13 is discharged, the inflatable body 100 is in a deflated state, and the volume of the inflatable body 100 is greatly reduced relative to its inflated state, thereby facilitating the storage of the inflatable body 100.

[0104] A plurality of tensioning members 20 are provided in the inflation chamber 13 of the inflatable body 100. The tensioning members 20 are connected to the first wall 11 and the second wall 12 by high-frequency welding, hot melting, adhesive bonding or other connection methods. After being tensioned, the tensioning members 20 provide tension to the first wall 11 and the second wall 12 to limit the deformation of the inflatable body 100, so that the inflatable body 100 can maintain a preset shape after being inflated.

[0105] Optionally, the plurality of tensioning members 20 may have different structures in different embodiments. For example, each tensioning member 20 may be a sheet-like tensioning member 21 or a wire-like tensioning member 22.

[0106] The sheet-like tensioning member 21 can have a single-layer or composite-layer structure depending on actual needs.

[0107] When the sheet-like tensioning member 21 is a single-layer sheet, it can be made of a polymer material, which may include, but is not limited to, one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic polyurethanes (TPU), polyethylene terephthalate (PET), ethylene-vinyl acetate (EVA) copolymer, and nylon. Understandably, in other embodiments, the main body of the single-layer sheet-like tensioning member 21 may also be made of materials other than polymer materials, such as fabric materials, wherein the fabric material may optionally be finely woven or form a mesh structure. The fabric material may be, but is not limited to, natural fiber fabrics (e.g., but not limited to, cotton, linen, wool, and silk) or synthetic fiber fabrics (e.g., but not limited to, polyester, polyethylene, and polypropylene fabrics).

[0108] When the sheet-like tensioning member 21 is a composite sheet, it is composed of two or more layers of sheet material bonded together by adhesive, welding or other means, and each layer of the multilayer sheet material can be made of the polymer material as described above or other materials as described above.

[0109] The linear tensioning member 22 comprises one or more threads that span the distance between the first wall 11 and the second wall 12 of the inflatable body 100, and may optionally be parallel or substantially parallel in space, for example, the threads being spaced apart from each other at equal intervals or in a manner that varies according to a certain pattern. The material of the one or more threads in the linear tensioning member 22 may be, but is not limited to, natural fibers (e.g., but not limited to, cotton, linen, wool, and silk) or synthetic fibers (e.g., but not limited to, polyester, polyethylene, and polypropylene). The linear tensioning member 22 is typically indirectly connected to the first wall 11 and the second wall 12 via a connector, which may be made of a polymeric material, but is not limited to, materials that facilitate welding of the first wall 11 and the second wall 12.

[0110] Examples of this application Figure 2 The air valve 200 shown can also be used on air mattresses or TPU air-filled foam mattresses.

[0114] refer to Figure 2 and Figure 4 , Figure 2This is an overall structural diagram of valve 200. Valve seat 202 is made of materials suitable for high-frequency applications, such as PVC (Polyvinyl Chloride), TPU (Thermoplastic Polyurethane), or PEVA (Polyethylene Vinyl Acetate). Valve core 203 is made of materials with good self-lubricating properties, such as POM (Polyoxymethylene) or PTFE (Polytetrafluoroethylene). Valve cover 207 and valve body 201 are made of materials with high strength and smoothness, such as ABS (Acrylonitrile Butadiene Styrene), PC (Polycarbonate), PMMA (Poly(methyl methacrylate)), or PP (Polypropylene).

[0115] For example, refer to Figure 2 and Figure 4 , Figure 4 This is an exploded view of the air valve 200. The air valve 200 includes: a valve body 201, a valve seat 202, a valve core 203, and a first seal 204. The valve seat 202 is connected to the valve body 201 to form a fluid passage 205, which communicates with a second passage 302 of the connector 300 described later. Figure 7B (As can be seen). The valve core 203 includes three vents 2031. The valve core 203 is located within the fluid channel 205, and the vents 2031 are connected to the fluid channel 205. The valve core 203 is rotatably disposed within the fluid channel 205 relative to the valve seat 202, so that the valve core 203 can be in a first position (i.e., Figure 7 The inflation state shown and Figure 8 The venting state shown) and the second position (i.e. Figure 9 Switching between rapid inflation / deflation states (as shown), the first seal 204 surrounds the valve core 203 and is confined between the valve body 201 and the valve seat 202. Preferably, the valve core 203 can rotate 360 ​​degrees relative to the valve seat 202 within the fluid passage 205.

[0116] In the first position, the valve core 203 is in contact with the inner wall 2051 of the fluid passage 205, and the first seal 204 contacts the valve core 203, causing the valve core 203 to contact the inner wall 2051 of the fluid passage 205 (in conjunction). Figure 6In the second position, the valve core 203 is spaced apart from the inner wall 2051 of the fluid passage 205, and the first sealing member 204 surrounds the valve core 203 and is spaced apart from the valve core 203.

[0117] For example, refer to Figure 5 Three ventilation openings 2031 are circumferentially (i.e. Figure 5 As shown in direction A, the three vents 2031 are spaced apart and connected to the fluid channel 205. However, this application embodiment does not limit the specific number and shape of the vents 2031. For example, there can be three fan-shaped vents 2031 as shown in this application embodiment, or there can be four fan-shaped or irregularly shaped vents 2031.

[0118] For example, refer to Figure 4 and Figure 5 The valve body 201 has eight supports 2011 on the side away from the valve seat 202. The eight supports 2011 are circumferentially spaced to form multiple air outlet holes 2012. For example, the valve body 201 can be constructed in a grid shape. The air outlet holes 2012 are connected to the fluid channel 205 to facilitate the flow of fluid (e.g., gas). One end of each support 2011 extends toward the valve seat 202 and is connected to the first connecting part 2013. The other end extends away from the valve seat 202 and is connected through the second connecting part 2014, which is located at the bottom end of the valve body 201.

[0119] In other words, the number of mesh supports 2011 for the bottom air inlet and outlet (i.e., air outlet through hole 2012) of the valve body 201 is 8, and the shape of the supports 2011 is arc-shaped. This application embodiment does not impose specific limitations on this number and shape, and it can also be three, five, ten, etc., and the shape can also be L-shaped, straight, etc.

[0120] For example, refer to Figure 5 and Figure 6 , Figure 5 This is a schematic diagram showing the valve cover 207 of the air valve 200 in the open state. Figure 6 This is a cross-sectional schematic diagram of the air valve 200.

[0121] For example, the first connecting portion 2013 is disposed on the inner wall of the valve body 201 and extends radially toward the fluid channel 205, that is, the inner wall of the valve body 201 protrudes to form the first connecting portion 2013. The valve seat 202 includes a first main body portion 2021, which is hollow inside and connected to the valve body 201 to form the fluid channel 205. The first main body portion 2021 extends axially (i.e., Figure 6Extending in the X direction (as shown), the first main body 2021 and the first connecting part 2013 are axially opposite and spaced apart, and together with the inner wall of the valve body 201, they form a receiving space 2022, and the first sealing member 204 is located in the receiving space 2022.

[0122] For example, the valve body 201 has a hook 2015 at the top of its inner wall. The hook 2015 and the first connecting part 2013 are spaced apart along the axial direction. The outer wall of the first main body 2021 has a mounting part 2023. The mounting part 2023 is configured to snap-fit ​​with the hook 2015 so that the valve seat 202 is connected to the valve body 201 and the first sealing member 204 is clamped in the receiving space 2022.

[0123] Those skilled in the art will understand that the mounting portion 2023 can be a recess 2106 or a hole, wherein, reference Figure 6A The groove 2106 can be provided at intervals around the outer wall of the first main body 2021, see reference. Figure 6B Alternatively, the grooves 2106 can be continuous. Those skilled in the art will understand that the number of grooves 2106 or holes spaced apart around the outer wall of the first main body 2021 corresponds to the number of hooks 2015. The number of grooves 2106 or holes and hooks 2015 can be 4, 6 or 8, but are not limited thereto.

[0124] For example, the outer periphery of the valve core 203 contacts the inner wall of the first main body portion 2021 of the valve seat 202 and the inner wall of the first connecting portion 2013 of the valve body 201. The first sealing member 204 has multiple ribs 2041 on the side facing the valve core 203. These ribs 2041 are spaced circumferentially, and all ribs 2041 abut against the outer periphery of the valve core 203. In the first position (i.e....) Figure 7 The inflation state shown and Figure 8 In the venting state shown, multiple ribs 2041 abut against the valve core 203; in the second position (i.e. Figure 9 (As shown in the rapid inflation / deflation state), multiple ribs 2041 surround the valve core 203 and are spaced apart from the valve core 203.

[0125] In other words, the valve seat 202 and the valve body 201 are connected together by a hook structure. The sealing ring of the air valve 200 (i.e., the first sealing element 204 mentioned above) is disposed between the valve seat 202 and the valve body 201. The sealing ring (i.e., the first sealing element 204 mentioned above) can be securely installed through the connection between the valve seat 202 and the valve body 201, and can prevent the sealing ring (i.e., the first sealing element 204 mentioned above) from loosening and falling off, thus affecting the sealing effect and reducing the risk of gas leakage in the inflatable product. The outer periphery of the valve core 203 contacts the inner wall of the valve seat 202 and the valve body 201, and the edge of the sealing ring (i.e., the first sealing element 204 mentioned above) is provided with ribs 2041. The ribs 2041 contact the outer periphery of the valve core 203 to achieve the sealing effect.

[0126] The length and number of ribs 2041 are not limited, but there must be at least one rib 2041. Specifically, the number of ribs 2041 can be one, two, or three, and the length can be 1mm, 2mm, 3mm, etc. Using shorter or thinner ribs 2041 can reduce the friction between the sealing ring (i.e., the first sealing element 204 mentioned above) and the valve core 203, thereby making it easier to flip the valve core 203.

[0127] For example, refer to Figure 5 and combined Figure 1 A portion of the outer periphery of the first main body 2021 protrudes outward to form a first abutting portion 2024, which abuts against the aforementioned inflatable main body 100. The first abutting portion 2024 is annular, meaning its axial projection is ring-shaped. Specifically, the wall of the inflatable main body 100 and the first abutting portion 2024 of the air valve 200 are connected by high-frequency welding or heat fusion to mount the air valve 200 on the wall of the inflatable main body 100.

[0128] For example, refer to Figures 4 to 6 The first main body 2021 is also connected to a connecting belt 2025. The connecting belt 2025 and the first abutting part 2024 are spaced apart along the axial direction. Along the axial direction, the connecting belt 2025 is located above the first abutting part 2024 (that is, the first abutting part 2024 is closer to the valve body 201). The end of the connecting belt 2025 away from the first main body 2021 is provided with a buckle through hole 2026.

[0129] For example, the air valve 200 also includes a valve diaphragm 206, which is located on the side of the valve core 203 facing the valve body 201. The valve diaphragm 206 is connected to the valve core 203 via a connecting rod 2061 and covers the three vents 2031 mentioned above.

[0130] For example, refer to Figure 7 and Figure 8 ,refer to Figure 7 , Figure 7This is a schematic diagram of the inflation state when the valve core 203 is in the first position. Figure 8 This is a schematic diagram of the venting state when the valve core 203 is in the first position.

[0131] User presses Figure 7 The valve core 203, in the first position shown, is in an inflated state. Within the airflow channel (i.e., fluid channel 205) defined by the valve seat 202, the valve core 203 flips to the deflated state in the first position. When the user deflates the air mattress or TPU inflatable foam mattress by squeezing and rolling it up, the one-way valve diaphragm 206 on the valve core 203 prevents external gas from flowing back into the air mattress or TPU inflatable foam mattress.

[0132] refer to Figure 9 , Figure 9 This is a schematic diagram of the state of the air valve core 203 when it is in the second position and is rapidly releasing or drawing air.

[0133] After use, the flip valve core of the air mattress or TPU inflatable foam mattress should be in the correct position. Figure 9 The second position shown allows for the rapid removal of gas from its interior.

[0134] When the user reopens the rolled-up TPU inflatable foam mattress, the flip valve core 203 is in the position... Figure 9 In the second position shown, due to the expansion of the foam itself, the TPU inflatable foam mattress can quickly draw in external air, causing the mattress to naturally unfold. When the air pump needs to replenish the air, the valve core 203 is flipped to... Figure 7 The inflation state shown in the first position.

[0135] In other words, reference Figure 7 and combined Figure 1 When in the inflation state, that is, when the aforementioned inflation body 100 needs to be inflated, the valve core 203 rotates within the fluid channel 205 until the valve diaphragm 206 moves axially (i.e., Figure 7 (As shown in the X direction) is located at the bottom end of the valve core 203, meaning that the valve diaphragm 206 is closer to the air outlet hole 2012 of the valve body 201. In other words, the valve diaphragm 206 only allows fluid to enter the inflation body 100. The inflation body 100 is inflated using an air pump. Under the pressure of the airflow from the air pump, the fluid will flow along... Figure 7 As shown by the arrow, the fluid flows (from end a to end b), pushing at least a portion of the valve diaphragm 206 toward the inflation body 100, causing the valve diaphragm 206 to separate from the vent 2031. At this time, part of the vent 2031 is in a conductive state, and the entire fluid channel 205 is in an open state, allowing the fluid to enter the air outlet through hole 2012 from the vent 2031 to inflate the inflation body 100.

[0136] During the inflation process of the inflation body 100, the air valve 200 can also be connected to an external inflation device using the connector 300.

[0137] For example, refer to Figures 7 to 7D and combined Figure 1 The fluid channel 205 is used to connect with the second channel 302 of the aforementioned connector 300.

[0138] For example, the valve seat 202 of the air valve 200 is connected to the inflation body 100 so that the valve body 201 of the air valve 200 is located in the inflation chamber. One end of the connector 300 is connected to the air valve 200, and the other end is connected to the nozzle of an external device (e.g., an air pump) to inflate or deflate the air mattress or TPU air foam mattress (deflation is performed by connecting the connector 300 with an air pump having a suction function). The wall of the inflation body 100 is connected to the connector 300 by high-frequency welding or heat fusion to mount the air valve 200 on the wall of the inflation body 100.

[0139] refer to Figure 7B , Figure 7B It is in Embodiment 1 of this application Figure 3 The air valve 200 shown is connected to the first type of connector 300 (see...) Figure 7A (See cross-sectional diagram for use in conjunction with the connector 300.) This connector 300 can be connected to the nozzle of an air pump (i.e., an external device) to inflate or deflate an air mattress or a TPU air foam mattress (deflating the mattress is done by connecting this connector 300 to an air pump with a suction function).

[0140] For example, refer to Figure 7A and Figure 7B , Figure 7A yes Figure 7B The diagram shows a perspective view of the connector 300. The connector 300 includes a connector body 301, which extends axially (i.e.,...) Figure 7A Extending in the X direction (as shown), the connector body 301 is hollow to form a second channel 302. The connector body 301 includes a first end 303 and a second end 304 arranged axially opposite each other. The first end 303 has a recess 305 that abuts against an external device (e.g., an air pump). The second end 304 has threads for threaded connection with an air valve 200, thereby connecting the air pump to the air valve 200 for inflating or deflating an air mattress or a TPU air-filled foam mattress. Preferably, the outer wall of the second end 304 has external threads, and the inner wall of the valve seat 202 has internal threads. The second end 304 is threaded to the valve seat 202 through the engagement of the internal and external threads. Those skilled in the art will understand that the second end 304 may have internal threads, and the outer wall of the valve seat 202 may have external threads, thereby threading the second end 304 to the valve seat 202.

[0141] It should be noted that the shape and number of the recesses 305 are not limited in the embodiments of this application. The specific shape can be selected according to the shape of the air pump, such as the L-shape shown in the embodiments of this application. The number can also be selected according to the shape of the air pump, such as one, two or more.

[0142] For example, a protrusion 306 is provided on the side wall of the connector body 301 near the second end 304. The protrusion 306 surrounds the side wall of the connector body 301 and is located on the top of the valve seat 202 of the air valve 200 described later. The shape of the protrusion 306 is not limited in this embodiment; it can be circular, quadrilateral, or other irregular shapes such as plum blossoms.

[0143] For example, multiple weight-reducing recesses 307 may also be provided on the outer periphery of the protrusion 306 to achieve the function of weight reduction. Meanwhile, the protrusions formed between adjacent weight-reducing recesses 307 facilitate user rotation of the connector 300 to mount it onto the valve seat 202. The multiple weight-reducing recesses 307 are circumferentially (i.e.,...) Figure 7A The spacing is set in direction A as shown. In this embodiment, the shape and number of weight-reducing recesses 307 are not specifically limited. For example, two arc-shaped weight-reducing recesses 307, three circular weight-reducing recesses 307, or four square weight-reducing recesses 307 can be provided, etc.

[0144] refer to Figure 7D , Figure 7D It is in Embodiment 1 of this application Figure 3 The air valve 200 shown is connected to the second type of connector 300 (see...) Figure 7C (A schematic diagram of the cross-section used in conjunction with the product.)

[0145] refer to Figure 7C , Figure 7C This is a three-dimensional schematic diagram of the second type of connector 300.

[0146] In other possible implementations, refer to Figure 7C and Figure 7D The connector 300 includes a connector body 301 and a protrusion 306, the connector body 301 being axially (i.e., Figure 7C Extending in the X direction (as shown), the connector body 301 is hollow inside to form a second channel 302. The connector body 301 includes a first end 303 and a second end 304 arranged opposite each other along the axial direction. The first end 303 is used to connect with an external device (e.g., an air pump) so that the external device can be inserted into the second channel 302. The second end 304 is threaded to be threadedly connected with an air valve 200, thereby connecting the air pump to the air valve 200 to inflate or deflate the air mattress or TPU air foam mattress.

[0147] Preferably, the outer wall of the second end 304 is provided with external threads, and the inner wall of the valve seat 202 is provided with internal threads. The second end 304 is threadedly connected to the valve seat 202 through the engagement of the internal and external threads. Those skilled in the art will understand that the second end 304 may be provided with internal threads, and the outer wall of the valve seat 202 may be provided with external threads, thereby threading the second end 304 to the valve seat 202. The protrusion 306 surrounds the outer periphery of the first end 303 and is placed on the top of the valve seat 202 of the air valve 200 described later. The shape of the protrusion 306 is not limited in this embodiment; it can be circular, quadrilateral, or other irregular shapes.

[0148] In other words, during the inflation process, the air pump inflates the air valve 200 through the connector 300, and the gas enters the fluid channel 205 through the second channel 302, and then flows through the air outlet through hole 2012 into the inflation chamber of the inflation body 100.

[0149] During inflation, if the airflow inside the inflation body 100 flows back outward, that is, along... Figure 7 If the flow is in the opposite direction of the arrow shown (i.e., from end b to end a), the backflowing gas will push the valve diaphragm 206 away from the inflation body 100, i.e. towards the vent 2031. In this way, the valve diaphragm 206 will close the vent 2031, thereby preventing the gas from flowing back.

[0150] refer to Figure 8 and combined Figure 1 In the deflation state, that is, when it is necessary to deflate the aforementioned inflation body 100, the valve core 203 rotates within the fluid channel 205 until the valve diaphragm 206 moves axially (i.e., Figure 8 (As shown in the X direction) is located at the top of the valve core 203, meaning that at this time the valve diaphragm 206 is far from the air outlet through hole 2012 of the valve body 201. In other words, at this time the valve diaphragm 206 only allows fluid to flow out from the inflation body 100. When the inflation body 100 is pressed at this time, because the gas pressure inside the inflation body 100 is greater than the external atmospheric pressure, the fluid will flow along... Figure 8 As shown by the arrow, the fluid flows (i.e. from end b to end a), pushing at least a portion of the valve diaphragm 206 away from the inflation body 100. At this time, part of the vent 2031 is in a conductive state, so that the valve diaphragm 206 is separated from the vent 2031, and the entire fluid channel 205 is in an open state, thereby allowing the fluid to flow out from the interior of the inflation body 100 to deflate the inflation body 100.

[0151] Similarly, during the deflation process, if gas from the external environment flows back into the inflation body 100, that is, along... Figure 8If the flow is in the opposite direction of the arrow shown (i.e., from end a to end b), the backflowing gas will push the valve diaphragm 206 toward the direction closer to the inflation body 100, i.e. toward the vent 2031. In this way, the valve diaphragm 206 will close the vent 2031, thereby preventing the gas from flowing back.

[0152] When the user needs to quickly deflate the inflation body 100, the valve core 203 is rotated to... Figure 9 The valve core 203 is positioned vertically relative to the fluid channel 205, minimizing obstruction of the fluid channel 205 and facilitating the rapid release of gas from the inflation body 100. When the user needs to rapidly inflate the inflation body 100, the valve core 203 can be rotated to... Figure 9 In the indicated state, that is, vertical relative to the fluid channel 205, the TPU inflatable foam mattress can quickly draw in external air due to the expansion of the foam itself, causing the mattress to unfold naturally. When the air pump needs to replenish the air, the valve core 203 is flipped to... Figure 7 The inflation position is shown. Valve core 203 from... Figure 7 and Figure 8 The first position shown is switched to Figure 9 During the second position shown, the user can rotate the valve core 203 to change the size of the fluid channel opening, thereby adjusting the inflation and deflation speed of the inflation body 100.

[0153] By way of example, the air valve 200 also includes a valve cover 207, referenced to Figure 10 , Figure 10 This is a cross-sectional schematic diagram showing the connection between the valve cover 207 and the valve seat 202 via threads on the valve cover 207 and external threads on one end of the valve seat 202. (Reference) Figure 10A , Figure 10A yes Figure 10 The diagram shows the structure of valve core 203.

[0154] In other possible implementations, the valve sealing ring (i.e., the first sealing element 204 mentioned above) adopts a rubber-coated structure and is disposed on the valve core 203 along the circumferential edge of the valve core 203. The sealing ring (i.e., the first sealing element 204 mentioned above) contacts the valve seat 202 and the inner wall of the valve body 201. At the same time, the ribs 2041 on the outer wall of the sealing ring (i.e., the first sealing element 204 mentioned above) contact the inner wall of the valve seat 202, which can achieve a better sealing effect.

[0155] refer to Figure 11 , Figure 11 This is a cross-sectional diagram showing the valve cover 207 connecting to the valve seat 202 via threads on the valve cover 207 and internal threads on one end of the valve seat 202. The valve core 203 is... Figure 10 or Figure 10A The valve core 203 shown.

[0156] For example, refer to Figures 10 to 11 The top of the valve cover 207 is provided with a snap-fit ​​part 2071, and the snap-fit ​​through hole 2026 of the connecting strip 2025 ( Figure 4 (As can be seen) The valve cover 207 is snapped into the latching part 2071 to connect the valve seat 202, thereby preventing the valve cover 207 from being lost. The valve cover 207 includes a first part 2072 and a second part 2073, which are radially spaced to form a connecting groove 2074. The connecting groove 2074 is used to receive the valve seat 202 and is threadedly connected to it. A second sealing element 2075 is provided in the connecting groove 2074 to ensure a sealed connection between the valve cover 207 and the valve seat 202.

[0157] For example, the valve cover 207 and the valve seat 202 can be Figure 10 The connection method shown has an internal thread on the outer wall of the connecting groove 2074, i.e., the second part 2073, which is radially oriented towards the fluid channel 205, and an external thread on the outer wall of the top end of the valve seat 202. The internal and external threads are threaded together to connect the valve cover 207 and the valve seat 202. Alternatively, it can be as follows: Figure 11 As shown in the connection method, the inner wall of the connecting groove 2074, that is, the first part 2072, is provided with external threads on the wall in the radial direction away from the fluid channel 205, and the inner wall of the top end of the valve seat 202 is provided with internal threads. The internal threads and external threads are threaded together to connect the valve cover 207 and the valve seat 202.

[0158] For example, combined Figure 5 The first part 2072 is hollow inside to communicate with the fluid channel 205. Multiple reinforcing ribs 2076 are provided on the inner wall of the first part 2072 radially toward the fluid channel 205. These reinforcing ribs 2076 are arranged circumferentially (i.e.,...). Figure 5 The valve cover 207 is spaced apart in the direction A shown to enhance its rigidity and improve the sealing effect of the valve 200 after the valve cover 207 is connected to the valve seat 202.

[0159] The embodiments of this application do not limit the number and shape of the reinforcing ribs 2076, which can be five, eight, ten, etc., and the shape can be a strip, a circle, or other irregular shape.

[0160] That is to say, in other possible implementations, refer to Figures 10 to 11 This application also provides a pneumatic valve 200, which includes a valve body 201, a valve seat 202, a valve core 203, and a first sealing element 204. The first sealing element 204 of the pneumatic valve 200 can also be configured as follows: Figure 10 or Figure 9As shown in the diagram. Valve seat 202 is connected to valve body 201 to form fluid passage 205, which is used to communicate with the second passage 302 of the aforementioned connector 300. Figure 7B or Figure 7D (As can be seen). The valve core 203 includes three vents 2031. The valve core 203 is located within the fluid channel 205, and the vents 2031 are connected to the fluid channel 205. The valve core 203 is rotatably disposed within the fluid channel 205 relative to the valve seat 202, so that the valve core 203 can be in a first position (i.e., Figure 7 The inflation state shown and Figure 8 The venting state shown) and the second position (i.e. Figure 9 Switching between the rapid inflation / deflation states shown, combined with... Figure 10A The first seal 204 surrounds the valve core 203 and is integrally formed with the valve core 203.

[0161] In the first position (i.e.) Figure 7 The inflation state shown and Figure 8 (As shown in the venting state), valve core 203 contacts the inner wall 2051 of fluid passage 205, and first seal 204 contacts the inner wall 2051 of fluid passage 205 (in combination). Figure 6 That is, including the inner wall of the first main body 2021 (described later) and the inner wall of the first connecting part 2013 (described later), and sealing the valve core 203 with the inner wall 2051 of the fluid passage 205; in the second position (i.e. Figure 9 (As shown in the rapid inflation / deflation state), the valve core 203 and the inner wall 2051 of the fluid channel 205 are spaced apart, and the first seal 204 and the inner wall 2051 of the fluid channel 205 are spaced apart.

[0162] For example, the first sealing element 204 adopts a rubber-coated structure and is disposed on the valve core 203 along the circumferential edge of the valve core 203. The first sealing element 204 contacts the valve seat 202 and the inner wall of the valve body 201. At the same time, the ribs 2041 on the outer wall of the first sealing element 204 contact the inner wall of the valve seat 202, which can achieve a better sealing effect.

[0163] In other words, the first sealing element 204 surrounds the valve core 203 and is integrally formed with the valve core 203, so that the valve core 203 is sealed to the valve seat 202 and the valve body 201. The first sealing element 204 has multiple ribs 2041 on the side facing the inner wall of the fluid channel 205. The multiple ribs 2041 are spaced apart circumferentially, and each of the multiple ribs 2041 abuts against the valve seat 202. In a first position, all the multiple ribs 2041 abut against the inner wall 2051 of the fluid channel 205; in a second position, the multiple ribs 2041 are spaced apart from the inner wall 2051 of the fluid channel 205.

[0164] Similarly, this application embodiment does not limit the length or number of the ribs 2041. The number of ribs 2041 can be one, two, three, four, five, etc., and the length can be 1mm, 2mm, 3mm, etc. Using shorter or thinner ribs 2041 can reduce the friction between the first seal 204 and the valve core 203, thereby making it easier to flip the valve core 203. Those skilled in the art will understand that the above... Figure 10 and Figure 11 The air valve 200 shown can also be used. Figure 7A , Figure 7C The connector 300 shown.

[0165] Those skilled in the art will understand that the connection method of the valve cover 207 to the valve seat via the internal or external thread provided at one end of the valve seat 202 does not affect the replacement use of the aforementioned two valve core 203 structures.

Example 2

[0167] refer to Figure 12 , Figure 12 This is a three-dimensional structural diagram of the air valve 200.

[0168] For example, refer to Figure 12 and Figure 13 The outer periphery of the first main body 2021 protrudes outward to form a second abutment portion 2027. The second abutment portion 2027 extends axially and close to the valve body 201, and is radially (i.e.,) with the first main body 2021. Figure 13 The annular grooves 2028 are arranged at intervals in the Y direction (as shown) to form annular grooves 2028. The annular grooves 2028 are used to receive the valve body 201 and are threadedly engaged with the outer wall of the valve body 201 to clamp the first seal 204 in the receiving space 2022.

[0169] For example, the axial projection of the second abutment portion 2027 includes a first straight segment 2029, a first arc segment 2101, a second straight segment 2102, a third straight segment 2103, a second arc segment 2104, and a fourth straight segment 2105 that are interconnected. The second abutment portion 2027 has a spindle-shaped structure. (Reference) Figure 13 , Figure 13 This is a cross-sectional diagram showing how the valve cover 207 is connected to the valve seat 202 via the threads on the valve cover 207 and the external threads provided at one end of the valve seat 202.

[0170] refer to Figure 15 , Figure 15 This is a cross-sectional diagram showing how the valve cover 207 is connected to the valve seat 202 via the threads on the valve cover 207 and the external threads provided at one end of the valve seat 202.

[0171] The valve sealing ring (i.e., the first sealing element 204 mentioned above) adopts a rubber-coated structure and is set on the valve core 203 along the circumferential edge of the valve core 203. The sealing ring (i.e., the first sealing element 204 mentioned above) contacts the valve seat 202 and the inner wall of the valve body 201. At the same time, the ribs 2041 on the outer wall of the sealing ring (i.e., the first sealing element 204 mentioned above) contact the inner wall of the valve seat 202, which can achieve a better sealing effect.

[0172] refer to Figure 14 , Figure 14 This is a cross-sectional schematic diagram of the valve seat 202 connected to the valve body 201 by threads.

[0173] The sealing ring (i.e., the first sealing element 204 mentioned above) is clamped between the valve seat 202 and the valve body 201 through the threaded connection between the valve seat 202 and the valve body 201, which can prevent the sealing ring (i.e., the first sealing element 204 mentioned above) from loosening and falling off, thus affecting the sealing effect.

[0174] The edge of the sealing ring (i.e., the first sealing element 201 mentioned above) is provided with ribs 2041, and the ribs 2041 contact the wall of the valve core 203 to achieve a sealing effect.

[0175] refer to Figure 16 , Figure 16 yes Figure 15 The diagram shows a cross-sectional view of the valve seat 202 connected to the valve body 201 via threads. The valve core 203 is... Figure 15 The valve core 203 shown.

[0176] refer to Figure 17 , Figure 17 This is a schematic diagram of the valve core 203.

[0177] The valve core 203 is provided with the aforementioned ventilation opening 2031, which is fan-shaped and divided into three equal parts. The ventilation opening 2031 is along the circumference of the valve core 203 (i.e., Figure 17 As shown in direction A), the vent 2031 is provided with continuous or intermittent annular blocks 2033 on its edge to block the valve diaphragm 206 ( Figure 16 As can be seen, this effectively solves the problem that the valve diaphragm 206 is stuck in the vent 2031 and cannot rebound during the pressing of the valve core 203.

[0178] In other words, the valve core 203 is provided with three baffles 2032, and the three baffles 2032 are arranged circumferentially (i.e. Figure 17 As shown in direction A, the three baffles 2032 are spaced apart to form ventilation openings 2031. One end of each baffle 2032 is connected to the inner wall of the valve core 203, and the other end is connected to the third connecting part 2034. The third connecting part 2034 is provided with a through hole 2035, and the connecting rod 2061 passes through the through hole 2035 to connect to the valve core 203.

[0179] Those skilled in the art will understand that the stop 2033 can be integrally formed with the valve core 203 or can be separately formed. The stop 2033 can also be set on the edge of the baffle 2032, and the number of stop 2033 set on it can be 1, 2, 3, 4, 5 or more, and the specific number is not limited.

[0180] refer to Figure 18 , Figure 18 This is a schematic diagram showing two independent baffles 2033 set on the edge of each vent 2031 of the valve core 203.

[0181] refer to Figure 19 , Figure 19 The vents 2031 of the valve core 203 are divided into four equal parts in a fan shape. Each vent 2031 of the valve core 203 is provided with an independent baffle 2033.

[0182] Those skilled in the art will understand that the number of baffles 2033 provided in the vent 2031 of the valve core 203 is not limited, and the number of baffles 2033 in a vent 2031 can be 1, 2, 3, 4, 5 or more, and the specific number is not limited.

[0183] The shape of the stop 2033 is also not limited; the shape of the stop 2033 can be as follows: Figure 17 The integrated annular stop 2033 shown can also be as follows: Figure 18 and Figure 19 The independent stop 2033 shown can block the valve diaphragm 206 ( Figure 16 As can be seen, the function of the vent 2031 is to allow the block to enter. Specifically, the shape of the block 2033 can be a protrusion, a rectangle, an arc, or a triangle.

[0184] Combination Figure 21 The baffle 2033 is disposed along the height H1 of the valve core at the bottom edge of the vent 2031 or the bottom edge of the baffle 2032. Of course, the baffle 2033 can also be disposed in the middle or other positions of the vent 2031 or baffle 2032 along the height direction of the valve core 203, as long as it can block the valve diaphragm 206 ( Figure 16 The effect is as shown. That is to say, along the axial direction (i.e. Figure 21 (in the X direction shown) the stop 2033 can be located at the bottom, middle or top of the inner wall of the vent 2031.

[0185] The length of the stop 2033 extending toward the through hole 2035 is 1.5mm-4mm, and the width extending in the circumferential direction A is 1.5mm-4mm. Preferably, the length is 2mm and the width is 1.5mm. Of course, the length and width of the stop 2033 can also be larger or smaller, and the specific values ​​are not limited.

[0186] The number and shape of the aforementioned ventilation openings 2031 are not limited, and can be achieved through baffles 2032, etc. Figure 18 The trisection shown can also be as follows: Figure 19 The diagram shows a four-eighths division, or a two-eighths, five-eighths, or six-eighths division using baffle 2032.

[0187] refer to Figure 19 , Figure 19 yes Figure 5 The diagram shows the structure of valve core 203.

[0188] refer to Figure 20 , Figure 20 This is a schematic diagram of the valve core 203.

[0189] The baffle 2032 is arc-shaped, which increases the contact area of ​​the valve core 203, making it easier to press the valve core 203. Of course, the baffle 2032 can also be a straight baffle 2032 as shown in the figure above.

[0190] The stop block 2033 is an annular block. One side of the stop block 2033 is connected to the inner wall of the vent 2031, and the other side extends in the direction toward the through hole 2035.

[0191] For example, refer to Figure 21 The maximum high-frequency outer diameter of the valve seat 202 of the air valve 200 is set at W4, which is 40mm to 120mm. This basically meets the requirements of TPU inflatable foam mattresses on the market for the air valve 200. Preferably, the maximum high-frequency outer diameter W4 of the valve seat 202 of the air valve 200 is 55mm (of course, it can also be other values ​​in the range of 40mm-120mm, such as 52mm-60mm or other specific values. Currently, the maximum high-frequency outer diameter of other valve seats 202 on the market is basically around 55mm. Therefore, preferably, the size W4 can also be 52 mm, 53 mm, 54 mm, 56 mm, 57 mm, 58 mm, 59 mm or 60mm).

[0192] Based on the maximum high-frequency outer diameter of the air valve 200, the maximum outer diameter W3 of the valve body 201 of the air valve 200 is set between 30mm and 110mm. Preferably, the outer diameter W3 of the valve body 201 of the air valve 200 is 45mm. Optionally, the outer diameter W3 of the valve body 201 of the air valve 200 can also be in other numerical ranges between 30mm and 110mm, such as 40mm-52mm or other specific values, such as 42mm, 45mm, 48mm, or 52mm.

Preferably, the maximum outer diameter W2 of the valve core 203 of the air valve 200 is 35mm. Optionally, the maximum outer diameter W2 of the valve core 203 of the air valve 200 can also be in other numerical ranges between 20mm and 100mm, such as 30mm-42mm or other specific values, for example, the size W2 can also be 32mm, 35mm, 38mm, or 42mm.

[0194] The outer diameter W1 of the valve diaphragm 206 is selected between 18mm and 108mm, and preferably, the outer diameter W1 of the valve diaphragm 206 is 30mm. Optionally, the outer diameter W1 of the valve diaphragm 206 can also be in other numerical ranges between 18mm and 108mm, such as 27mm-40mm or other specific values, such as 29mm, 32mm, 35mm, 37mm, or 40mm.

[0195] Based on the maximum high-frequency outer diameter of the air valve 200, the inner diameter W of the valve core 203 of the air valve 200 can be set between 16mm and 96mm to maximize the size of the air inlet and outlet. Preferably, the maximum outer diameter W of the valve core 203 of the air valve 200 is 26mm. Optionally, the maximum outer diameter W of the valve core 203 of the air valve 200 can also be in other numerical ranges between 16mm and 96mm, such as 24mm-37mm or other specific values, such as 26mm, 29mm, 32mm, 34mm, or 37mm.

[0196] The thickness of the valve core 203 of the air valve 200 is H1≥3mm, and the airflow channel (i.e. the fluid channel 205 mentioned above) formed by the outer arc surface of the valve core 203, the valve seat 202, and the valve body 201 is a concentric circle structure. This ensures that the valve core 203 can rotate smoothly in the airflow channel (i.e. the fluid channel 205 mentioned above) without causing discomfort such as jamming.

[0197] The thickness H2 of the valve diaphragm 206 is 0.5mm to 10mm, which can ensure the opening / closing effect of the vent 2031 of the air valve 200 to the greatest extent while meeting the sealing requirements of the valve core 203. Preferably, the thickness H2 of the valve diaphragm 206 is 1.2mm (as above).

[0198] To facilitate user operation of the valve core 203, the force required to flip the valve core 203 is less than 0.5N, preferably 0.1N, 0.15N, 0.2N, 0.25N, 0.3N, 0.4N, or 0.45N.
