Abstract
Description
Technical Field
[0001] The present invention relates to the field of valves, and in particular to an integrated inflation and deflation valve and an inflation body. Background Art
[0002] In today's fast-paced urban life and high work pressures, people are increasingly seeking more ways to relax and enjoy their lives. For example, massage pools with both massage and relaxation features allow people to relax and enjoy themselves, thus gaining widespread popularity. Water skiing, a sport that requires full-body coordination, has become a popular aquatic sport combining relaxation and recreation. Inflatable water skis are a common type of water ski, popular among water skiing enthusiasts due to their durability, ease of storage, portability, and transportation.
[0003] However, for inflatable products such as massage pools and inflatable water skis, when the gas temperature rises due to factors such as exposure to sunlight, the number of molecules hitting the pool wall per unit time will increase because the volume of the gas in the cavity remains unchanged. Therefore, the average force hitting the pool wall will also increase, and the gas pressure in the cavity of the inflatable product will increase, resulting in a decrease in the appearance and life of the inflatable product.
[0004] The current common solution is to install separate inflating and deflation components on the inflatable product, which is cumbersome to install and expensive. Another solution is to add a manual exhaust unit on the inflatable component, but this has the problem that exhausting requires manual operation, pressure relief is not real-time, and the pressure relief pressure cannot be accurately controlled. Summary of the Invention
[0005] The present invention aims to address the current pressure relief issues with inflatable products, such as the need for multiple valve bodies, resulting in cumbersome and costly installation, or the need for manual deflation, resulting in a lack of real-time pressure relief and an inability to precisely control the pressure relief. The present invention provides an integrated inflation and deflation valve that automatically and precisely controls pressure relief in real time, while also simplifying installation and reducing costs.
[0006] In order to solve the above technical problems, the embodiment of the present invention discloses an integrated inflation and deflation valve for a first object, the first object including a gas chamber, and the integrated inflation and deflation valve including:
[0007] a valve body, the valve body being provided with a first channel and a second channel, wherein one port of the first channel and one port of the second channel are respectively used to communicate with the interior of the gas chamber, and the other port of the first channel and the other port of the second channel are respectively used to communicate with the exterior of the gas chamber;
[0008] An inflatable component is provided on the first ventilation path of the first channel, and the inflatable component is movable relative to the first ventilation path to switch between a first position and a second position;
[0009] In the first position, the first ventilation path is in a conducting state, and in the second position, the first ventilation path is in a sealed state;
[0010] A deflation component is provided on the second ventilation path of the second channel, and the deflation component is movable relative to the second ventilation path to switch between a third position and a fourth position;
[0011] In the third position, the second ventilation path is in a conducting state, and in the fourth position, the second ventilation path is in a sealed state; wherein,
[0012] When the first ventilation path is in the conducting state and the second ventilation path is in the sealed state, the gas chamber can be inflated through the integrated inflation and deflation valve;
[0013] When the first ventilation path is in a sealed state and the second ventilation path is in a conducting state, the gas chamber can be deflated through the integrated inflation and deflation valve.
[0014] Using this technical solution, the first ventilation path can be opened and the second ventilation path sealed to inflate the gas chamber. When the pressure in the gas chamber is excessive, the first ventilation path can be sealed and the second ventilation path opened to release the pressure from the gas chamber. The integrated inflation and deflation valve of this embodiment integrates both inflation and deflation functions, and can also automatically release pressure in real time when the pressure in the gas chamber rises.
[0015] As a specific embodiment, when the first ventilation path is in a conducting state, the gas chamber can be deflated through the integrated inflation and deflation valve.
[0016] As a specific embodiment, the inflatable component can move relative to the first ventilation path under the action of an external force to be in a first position; the inflatable component can move relative to the first ventilation path after the external force is lost to be in a second position; the deflated component can move relative to the second ventilation path under the action of an external force to be in a third position, and the deflated component can move relative to the second ventilation path after the external force is lost to be in a fourth position.
[0017] As a specific embodiment, the first channel extends along a first direction, and the inflatable component can move along the first direction relative to the first ventilation path toward one end of the first channel under the action of an external force so as to be in a first position; or, the inflatable component can move along the first direction relative to the first ventilation path toward another end of the first channel after the external force is lost so as to be in a second position.
[0018] As a specific embodiment, the external force acting on the inflatable component includes a force applied by a user.
[0019] As a specific embodiment, the inflatable component includes:
[0020] a first valve core, the first valve core being capable of moving in a first direction toward a port of the first channel under the action of an external force, so as to place the first ventilation path in a conducting state;
[0021] The first elastic member is elastically connected to the valve body through the first elastic member; the first elastic member is used to reset the first valve core after movement, so that the first ventilation path is in a sealed state.
[0022] As a specific embodiment, the inflation component also includes a first sealing plate, which is installed on the first valve core. When the first valve core moves along the first direction toward a port of the first channel under the action of external force, the first sealing plate can be separated from the valve body to put the first ventilation path in a conducting state; after the first valve core is reset, the first sealing plate can fit with the valve body to put the first ventilation path in a sealed state.
[0023] As a specific embodiment, a fixing portion is provided in the first channel. Along the first direction, one end of the first elastic member abuts against the fixing portion, and the other end of the first elastic member abuts against the first valve core.
[0024] As a specific embodiment, the inflation component further includes a valve core cap, which is provided at the end of the first valve core, and the other end of the first elastic member abuts against the end surface of the valve core cap.
[0025] As a specific embodiment, the fixing portion is provided with a first mounting through hole, and the first mounting through hole is provided with at least two notches; the first valve core passes through the first mounting through hole, and the first valve core is provided with a clamping block capable of cooperating with each notch;
[0026] When the first ventilation path is in a sealed state, each block is located in a matching notch;
[0027] The first valve core can move relative to the first mounting through hole along the first direction, so that each block moves along the first direction to separate from each notch, and the first valve core can rotate circumferentially to make each block rotate to engage with the edge of the first mounting through hole along the first direction, and the first ventilation path is in a conducting state; wherein, the circumference surrounds the first direction.
[0028] Using this technical solution, the first valve core can be manually pushed in a first direction toward one end of the first channel, causing each clamping block to move out of the respective notches in the first direction. Subsequently, by rotating the first valve core, each clamping block can be engaged in the first direction with the edges between the notches on the first mounting hole, thereby opening the first ventilation path and connecting the gas chamber to the outside world. This achieves the effect of manually deflation of the gas chamber, making the first object easier to carry and transport. During the deflation process, the user does not need to continuously apply external force to the first valve core, making operation more convenient and improving the user experience.
[0029] As a specific embodiment, the inflation component includes an end cover, which is provided with a hook-shaped clamping joint at intervals. The end cover can be inserted into the first channel from the other port of the first channel. After the end cover rotates around its own axis, the clamping joint can be clamped with the fixed part along the first direction to connect the end cover to the valve body.
[0030] As a specific embodiment, the inflation component further includes a second sealing sheet, which is provided on the end cover; when the end cover is connected to the valve body, the second sealing sheet fits tightly against the valve body, enabling the first ventilation path to be in a sealed state.
[0031] By adopting the above technical solution, double sealing of the first channel can be achieved through the first sealing sheet and the second sealing sheet, so that the sealing performance of the first channel is better to prevent gas leakage in the gas chamber.
[0032] As a specific embodiment, the second channel extends along the first direction, and the deflation component moves forward along the second direction relative to the second ventilation path under the action of an external force to be in a third position; alternatively, the deflation component can move backward along the second direction relative to the second ventilation path after the external force is removed to be in a fourth position; wherein the first direction and the second direction intersect.
[0033] As a specific embodiment, the external force acting on the deflation component includes the gas pressure in the gas chamber.
[0034] As a specific embodiment, the deflation component includes:
[0035] a second valve core, the second valve core being capable of moving forward in a second direction under the action of an external force, so as to place the second ventilation path in a conducting state;
[0036] The second elastic member, the second valve core is elastically and sealedly connected to the valve body through the second elastic member; the second elastic member is used to reset the moved second valve core to put the second ventilation path in a sealed state.
[0037] As a specific embodiment, the valve body is provided with a second mounting through hole extending along the second direction, and the second valve core includes:
[0038] A support rod extends in the second direction and is disposed in the second mounting hole in a manner that is movable in the second direction; one end of the support rod extends out of the second mounting hole and is sealedly connected to the channel wall of the second channel, and the other end of the support rod extends out of the second mounting hole;
[0039] An elastic top cover, one end of which is connected to the other end of the support rod; one end of the second elastic member abuts against the other end of the elastic top cover, and the other end of the second elastic member abuts against the valve body; the elastic top cover can seal the upper end of the second mounting through hole along the second direction to isolate the second mounting through hole from the outside;
[0040] The second mounting through hole is connected to the gas chamber through the second channel, so that the gas in the gas chamber can act on the elastic top cover;
[0041] In the third position, one end of the support rod is separated from the channel wall of the second channel along the second direction;
[0042] In the fourth position, one end of the support rod is connected to the channel wall of the second channel.
[0043] As a specific implementation, the cross-sectional area of the elastic top cover is larger than the cross-sectional area of the support rod.
[0044] By adopting the above technical solution, it is possible to more easily open the second ventilation path for pressure relief when pressure relief is required, and to more easily close the second ventilation path after pressure relief is completed.
[0045] As a specific implementation, the surface of the elastic top cover is uneven.
[0046] By adopting the above technical solution, the uneven surface of the elastic top cover can provide more space for the movement of the second valve core, making it easier to move the second valve core a larger distance in the second direction, thereby increasing the cross-sectional area of the second ventilation path and facilitating rapid pressure relief.
[0047] As a specific embodiment, along the first direction, the second channel includes a second channel first section and a second channel second section; the second channel first section is used to communicate with the gas chamber;
[0048] In the third position, the first section of the second channel is connected to the second section of the second channel;
[0049] In the fourth position, the first section of the second channel and the second section of the second channel are separated.
[0050] As a specific embodiment, the first section of the second channel and the second section of the second channel are stacked in the second direction, and the first section of the second channel and the second section of the second channel are connected by a connecting channel extending along the second direction;
[0051] When the second valve core moves forward in the second direction under the action of an external force, the support rod is separated from the connecting channel, the first section of the second channel is connected to the second section of the second channel, and the second ventilation path is in a conducting state;
[0052] When the second valve core moves in the opposite direction along the second direction, the support rod is inserted into the end of the connecting channel and is sealed with the channel wall of the first section of the second channel. The first section of the second channel is separated from the second section of the second channel, so that the second ventilation path is in a sealed state.
[0053] As a specific embodiment, the deflation assembly further includes a third sealing sheet mounted on the support rod; when the second valve core moves forward in the second direction under the action of an external force, the third sealing sheet separates from the channel wall of the first section of the second channel, the first section of the second channel communicates with the second section of the second channel, and the second ventilation path is in a conducting state;
[0054] When the second valve core moves in the opposite direction along the second direction, the third sealing sheet can fit with the channel wall of the first section of the second channel, and the first section of the second channel is separated from the second section of the second channel, so that the second ventilation path is in a sealed state.
[0055] As a specific embodiment, the deflation assembly also includes a cover body, which is connected to the valve body. The cover body and the other end of the elastic top cover form a cavity isolated from the second mounting through hole. The second elastic member is located in the cavity, and the other end of the second elastic member abuts against the cover body.
[0056] As a specific embodiment, the cavity is communicated with the outside of the gas chamber.
[0057] By adopting the above technical solution, the cavity is always connected to the outside world, and the pressure in the cavity is always the same as the outside pressure, so that the size of the deflation pressure is only determined by the elastic force of the second elastic member and is not affected by external temperature changes. Therefore, the deflation pressure can be kept in a stable state.
[0058] As a specific embodiment, the deflation component further includes a plug connected to the cover body, the other end of the second elastic member abuts against the plug, and the plug can move relative to the cover body along the second direction.
[0059] As a specific implementation, the plug is threadedly connected to the cover body.
[0060] By adopting the above technical solution, the compression amount of the second elastic member along the second direction can be adjusted by rotating the plug to move it relative to the cover body in the second direction, and then the pressure of the second elastic member acting on the second valve core can be adjusted, thereby adjusting the pressure relief value of the gas chamber.
[0061] Another embodiment of the present application further discloses an inflatable body, including a gas chamber and the above-mentioned integrated inflation and deflation valve, wherein one port of the first channel and one port of the second channel are respectively connected to the interior of the gas chamber, and another port of the first channel and another port of the second channel are respectively connected to the outside of the gas chamber.

[0075] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0076] refer to Figures 1 to 4 , the embodiment of the present invention discloses an integrated valve for inflation and deflation, including a valve body 10. Figure 2 and Figure 4As shown, a first channel 11 and a second channel 12 are provided within the valve body 10. An inflation assembly 20 is provided on the first ventilation path of the first channel 11. The inflation assembly 20 is movable relative to the first ventilation path to switch between a first position and a second position. In the first position, the first ventilation path is in an open state; in the second position, the first ventilation path is in a sealed state. A deflation assembly 30 is provided on the second ventilation path of the second channel 12. The deflation assembly 30 is movable relative to the second ventilation path to switch between a third position and a fourth position. In the third position, the second ventilation path is in an open state; in the fourth position, the second ventilation path is in a sealed state.
[0077] Illustratively, the first ventilation path and the second ventilation path refer to the paths through which gas flows in the first channel 11 and the second channel 12, respectively. Illustratively, the first position and the third position can each be a specific position at which the first ventilation path and the second ventilation path are in a conductive state, or can also be a specific position range at which the first ventilation path and the second ventilation path are in a conductive state. This is not a limitation in this embodiment.
[0078] The integrated inflation / deflation valve of this embodiment is used for a first object (not shown) comprising a gas chamber. For example, the first object is a massage pool, an inflatable water ski, or other similar inflatable product having a gas chamber. One end (e.g., the outlet) of the first channel 11 and one end (e.g., the inlet) of the second channel 12 of the integrated inflation / deflation valve are respectively configured to communicate with the interior of the gas chamber, while another end (e.g., the inlet) of the first channel 11 and another end (e.g., the outlet) of the second channel 12 are respectively configured to communicate with the exterior of the gas chamber.
[0079] When the first ventilation path is in an open state and the second ventilation path is in a sealed state, the gas chamber can be inflated via the integrated inflation / deflation valve. For example, the inflation device can allow gas to enter the first channel from another port of the first channel 11, flow through the first ventilation path, and then to one port of the first channel 11, thereby inflating the gas chamber.
[0080] When the first ventilation path is sealed and the second ventilation path is open, the gas chamber can be deflated through the integrated inflation / deflation valve. For example, after the gas chamber is inflated, when the gas pressure therein increases (e.g., when the gas temperature in the gas chamber increases due to exposure to sunlight, etc.), the second ventilation path is opened under the action of the gas pressure, and the gas in the gas chamber enters the second channel through one end of the second ventilation path, circulates in the second ventilation path, and is released to the outside of the gas chamber through the other end of the second channel, thereby depressurizing the gas chamber and preventing damage to the gas chamber caused by the increased gas pressure within the gas chamber.
[0081] For example, after the gas chamber is inflated, both the first and second ventilation paths are sealed. If the pressure in the gas chamber is too high, the first ventilation path is sealed and the second ventilation path is open, allowing the gas chamber to release pressure. After the gas chamber is depressurized, both the first and second ventilation paths are sealed again. If the pressure in the gas chamber rises again, the first ventilation path is sealed again and the second ventilation path is open, allowing the gas chamber to release pressure again through the second ventilation path.
[0082] That is, the integrated inflation and deflation valve of the present application integrates the inflation and deflation functions, and can automatically release the pressure in real time when the pressure in the gas chamber increases.
[0083] For example, when the inflation device is directly pressed to put the first ventilation path into a conducting state, the gas chamber is connected to the outside world, and the gas in the gas chamber can enter from one port of the first channel and flow through the first ventilation path to the other port of the first channel, leading to the outside of the gas chamber, thereby achieving the effect of manually relieving the pressure of the gas chamber.
[0084] Continue to refer to Figure 4 In this embodiment, the first channel 11 is along the first direction (such as Figure 4 The inflatable component 20 can move relative to the first ventilation path toward one end of the first channel 11 along the first direction under the action of an external force (as shown in the X direction). Figure 4 Alternatively, the inflatable component 20 can move in the first direction relative to the first ventilation path toward the other end of the first channel 11 after the external force is lost (as shown in the D direction) Figure 4 E in the middle) to be in the second position. Exemplarily, the external force acting on the inflatable component 20 includes the force applied by the user. That is, the user can apply an external force to the inflatable component 20 (such as pressing the inflatable component 20 with the inflatable device to apply an external force) to move the inflatable component 20 toward one end of the first channel 11 connected to the gas chamber. When it moves to the first position that enables the first ventilation path to be connected, the gas can flow from the outside of the gas chamber to the inside of the gas chamber to inflate the gas chamber. After the external force on the inflatable component 20 stops being applied (such as removing the inflatable device), the inflatable component 20 can move to the second position that seals the first ventilation path, blocking the flow between the inside and outside of the gas chamber, and stopping inflating the gas chamber.
[0085] Reference Figure 2 and Figure 4In this embodiment, the inflatable component 20 includes a first valve core 21 and a first elastic member 25. The first valve core 21 can move along a first direction toward a port of the first channel 11 under the action of an external force, so that the first ventilation path is in a conductive state. The first valve core 21 is elastically connected to the valve body 10 through the first elastic member 25; the first elastic member 25 is used to reset the first valve core 21 after movement, so that the first ventilation path is in a sealed state. That is, when the gas chamber needs to be inflated, the second ventilation path is in a sealed state. The first valve core 21 can be moved by an external force (such as applying an external force to the first valve core 21 by pressing it with an inflatable device) to make the first ventilation path conductive and inflate the inflatable chamber. After the inflation is completed, the external force is removed (such as removing the inflatable device), and the first valve core 21 is reset by the first elastic member 25, sealing the first ventilation path, and stopping inflating the gas chamber. At this time, the gas chamber is in a cut-off state from the outside world and maintains a certain pressure.
[0086] Reference Figure 5 The first valve core 21 includes a valve core head 211 and a rod 212 connected to the valve core head 211 .
[0087] Reference Figure 6 and Figure 7 , and refer to Figure 4 , a fixing portion 15 is provided in the first channel 11 for installing the inflatable component 20. The fixing portion 15 extends along the second direction, and its edge is sealed and connected to the inner wall of the first channel 11. The fixing portion 15 divides the first channel 11 into two chambers along the first direction. The space between the fixing portion 15 and one end of the first channel 11 connected to the gas chamber is the first chamber 111, and the space between the fixing portion 15 and the other end of the first channel 11 connected to the outside is the second chamber 112. A first mounting through hole 16 is provided on the fixing portion 15, and the rod portion 212 of the first valve core 21 is provided through the first mounting through hole 16 along the first direction. The valve core head 211 is located in the first chamber 111, and the rod portion 212 slides through the first mounting through hole 16 and extends to the second chamber 112. The first elastic member 25 is sleeved on the rod portion 212 extending into the second chamber 112 , and one end of the first elastic member 25 abuts against the fixing portion 15 , and the other end of the first elastic member 25 abuts against the end of the first valve core 21 .
[0088] In this embodiment, the stem portion 212 of the first valve core 21 moves in a first direction toward one end of the first channel 11 under the action of an external force (e.g., by applying an external force to the end of the stem portion 212 through an inflating device). That is, when the valve core head portion 211 moves away from the fixing portion 15, the first elastic member 25 is compressed in the first direction, the first valve core 21 is in the first position, the first ventilation path is open, and the gas chamber can be inflated. After the stem portion 212 loses the action of the external force (e.g., by removing the inflating device), the first elastic member 25 returns to its original position, and its elastic force drives the first valve core 21 to move in the first direction toward the other end of the first channel 11, so that the first valve core is in the second position, the first ventilation path is sealed, and the inflation chamber is isolated from the outside world.
[0089] Exemplarily, the inflatable assembly 20 further includes a valve core cap 23, which is disposed at the end of the stem portion 212 of the first valve core 21. The other end of the first elastic member 25 abuts against the end surface of the valve core cap 23. The valve core cap 23 facilitates the installation of the first valve core 21 and the first elastic member 25.
[0090] Continue to refer to Figure 4 , supplemented by reference Figure 6 In the first chamber 111, the fixing portion 15 is provided with a first annular sealing support 17 protruding in a first direction. The inflatable assembly 20 also includes a first sealing sheet 22, which is engaged with the groove of the valve core head 211 of the first valve core 21 and can move with the first valve core 21.
[0091] In this embodiment, the second ventilation path is in a sealed state, and an external force acts on the rod 212 (such as applying an external force to the end of the rod 212 by pressing the rod 212 with an inflatable device) to move the first direction of the first valve core 21 toward one end of the first channel 11, that is, when the valve core head 211 moves in a direction away from the fixed portion 15, the first sealing plate 22 is separated from the first sealing support 17, so that the first ventilation path is in a conductive state, the gas chamber is connected to the outside world, and the gas chamber can be inflated. After the external force is removed (such as removing the inflatable device), the first valve core 21 moves along the first direction toward the second chamber 112 under the action of the first elastic member 25, that is, the valve core head 211 moves toward the fixed portion 15, so that the first sealing plate 22 can fit with the first sealing support 17, the first ventilation path is in a sealed state, the gas chamber is isolated from the outside world, and inflation stops.
[0092] Reference Figure 5 and Figure 6 At least two notches are provided on the first mounting through hole 16 in the first channel 11, and each notch is provided facing the rod portion 212 of the first valve core 21; a clamping block that can cooperate with each notch is provided on the first valve core 21. This embodiment is described by taking the example that the number of notches and clamping blocks are both two.
[0093] For example, the first mounting hole 16 is provided with a circular ring protruding in the first direction toward the first chamber 111. The circular ring is provided with a first notch 161 and a second notch 162, evenly spaced apart. The first valve core 21 is correspondingly provided with a first clamping block 213 and a second clamping block 214 protruding from the stem 212. When the first ventilation path is in a sealed state, the first clamping block 213 is located within the first notch 161, and the second clamping block 214 is located within the second notch 162.
[0094] When the first valve core 21 moves in the first direction relative to the first mounting hole 16 toward one end of the first passage 11, the first and second retaining blocks 213, 214 move with the first valve core 21 in the first direction and separate from the first and second notches 161, 162, respectively. Thereafter, the first valve core 21 can rotate circumferentially (i.e., an external force is applied to the first valve core 21 to cause it to rotate), causing the first and second retaining blocks 213, 214 to rotate axially together (circumferentially around the first direction), interlacing with the first and second notches 161, 162, respectively. That is, in the first direction, the first retaining block 213 does not correspond to the first notch 161, and the second retaining block 214 does not correspond to the second notch 162. Instead, the first and second retaining blocks 213, 214 correspond to the edge of the first mounting hole 16 between the first and second notches 161, 162.
[0095] After the external force is removed, due to the elastic force of the first elastic member, the first clamping block 213 and the second clamping block 214 are clamped with the edge of the first mounting hole 16 along the first direction. At this time, the first ventilation path is in a conducting state, and the gas in the gas chamber can pass through the first channel to the outside.
[0096] This arrangement allows for manual deflation of the gas chamber. Specifically, after manually pushing the first valve core 21 in a first direction toward one end of the first channel 11, the blocks move out of their respective notches in the first direction. Subsequently, by rotating the first valve core 21, the blocks can be engaged along the first direction at the edges between the notches on the first mounting hole 16. This opens the first ventilation path, connecting the gas chamber to the outside world, achieving the effect of manually deflation of the gas chamber and making the first object easier to carry and transport. During the deflation process, the user no longer needs to constantly apply external force to the first valve core 21, making operation more convenient and enhancing the user experience.
[0097] In other embodiments, the number of the notches may be greater than or equal to the number of the blocks, and the number of the notches and the number of the blocks may be greater than two.
[0098] Reference Figure 2 and Figure 4 , while referring to Figure 6 and Figure 7The inflatable component 20 further includes an end cap 26, the end of which is provided with a hook-shaped clamping joint 261 at intervals. The end cap 26 can be inserted into the first channel 11 from the other end of the first channel 11 along the first direction (i.e., inserted into the second chamber 112 of the first channel 11). Correspondingly, as Figure 7 The mounting portion is provided with a clearance notch 151 for the clearance joint 261. The clamping joint 261 extends from the second chamber 112 to the first chamber 111 through the clearance notch. After that, the end cover 26 rotates around its own axis, and the clamping joint 261 can be clamped with the fixing portion 15 along the first direction. Figure 4 and Figure 6 As shown, the end cover 26 is connected to the valve body 10.
[0099] Continue to refer to Figure 4 The inflatable component 20 further includes a second sealing sheet 27, which is provided on the end cover 26; when the end cover 26 is connected to the valve body 10, the second sealing sheet 27 is tightly fitted with the valve body 10, so that the first ventilation path is in a sealed state. For example, referring to Figure 7 Inside the second chamber 112, an annular second sealing support 18 is provided on the fixing portion 15. The second sealing support 18 is used to fit the second sealing sheet 27, thereby facilitating a better seal for the second sealing sheet 27. Furthermore, the second sealing sheet 27 is made of silicone, which can act as a buffer when the end cap 26 is installed. At the same time, the silicone material is deformable, which enhances the sealing performance.
[0100] In this embodiment, double sealing of the first ventilation path is achieved by the first sealing sheet 22 and the second sealing sheet 27, thereby ensuring the sealing of the channel and preventing air leakage.
[0101] During use, when it is necessary to inflate the gas chamber of the first object, the second ventilation path is kept in a sealed state. First, the end cover 26 is rotated to disengage the clamping joint 261 from the mounting portion, and the end cover 26 is removed. Afterwards, an external force is applied to the first valve core 21 through the inflation device to compress the first elastic member 25, so that the first valve core 21 moves along the first direction toward a port of the first channel 11. When it moves to the first position, the first sealing plate 22 separates from the first sealing support 17, so that the first ventilation path is in a conductive state, and the inflation device can inflate the gas chamber. After the inflation is completed, the inflation device is removed, and the first valve core 21 moves along the first direction toward the second chamber 112 under the action of the first elastic member 25, so that the first sealing plate 22 can fit with the first sealing support 17, the first ventilation path is in a sealed state, and the gas chamber is isolated from the outside world. Then, the end cover 26 is inserted into the first channel 11 and is engaged with the mounting portion through the engaging joint 261 , so that the second sealing sheet 27 fits with the second sealing support 18 , thereby achieving double sealing of the first ventilation path.
[0102] Furthermore, in this embodiment, the deflation component 30 can move relative to the second ventilation path under the action of an external force to be in the third position, and the deflation component 30 can move relative to the second ventilation path to be in the fourth position after the external force is lost. For example, the second channel 12 extends along the first direction, and the deflation component 30 moves along the second direction ( Figure 2 and Figure 4 Z direction) relative to the positive direction of the second ventilation path ( Figure 2 and Figure 4 Alternatively, the deflation component 30 can reverse along the second direction relative to the second ventilation path after losing the external force ( Figure 2 and Figure 4 The first direction and the second direction intersect. In this embodiment, the second direction is perpendicular to the first direction. In other embodiments, the first direction may not be perpendicular to the second direction.
[0103] The first channel 11 and the second channel 12 both extend along the first direction, which can simplify processing and minimize the volume of the valve body. In another embodiment, the first channel 11 and the second channel 12 are not arranged in parallel.
[0104] Reference Figure 2 and Figure 4 The deflation component 30 includes a second valve core 33 and a second elastic member 35. The second valve core 33 can be moved in the second direction (eg Figure 2 and Figure 4 The valve body 10 is connected to the second valve core 33 by a second elastic member 35. The second elastic member 35 is used to return the moved second valve core 33 to its original position, sealing the second vent path. Furthermore, the external force acting on the deflation assembly includes the gas pressure within the gas chamber.
[0105] That is, the second elastic member 35 can provide a set value of pressure for the second valve core 33, so that the second valve core 33 is sealed with the valve body 10. When the pressure in the gas chamber is greater than the set value, the second valve core 33 can be moved forward in the second direction, so that the second ventilation path is in a conductive state, and the gas chamber is connected to the outside to relieve pressure. When the pressure value in the gas chamber drops below the pressure setting value, the second valve core 33 moves in the reverse direction (such as the second direction) under the action of the second elastic member 35. Figure 2 and Figure 4The valve body 10 then moves (as shown in the R direction) to restore its sealed connection with the valve body 10, sealing the second vent path, blocking the gas chamber from the outside world, and stopping pressure relief. Thus, this embodiment enables automatic pressure relief in the gas chamber when the pressure exceeds the set pressure, preventing deformation of the first object caused by excessive gas chamber pressure, thereby extending the service life of the first object. Furthermore, the relief pressure can be precisely controlled during this process.
[0106] Reference Figure 4 , while referring to Figure 2 The valve body 10 is provided with a second mounting hole 19 extending in the second direction. The second valve core 33 includes a support rod 331 extending in the second direction and an elastic top cover 332. The support rod 331 is disposed within the second mounting hole 19 so as to be movable in the second direction. One end of the support rod 331 extends through the second mounting hole 19 and is sealedly connected to the channel wall of the second channel 12. The other end of the support rod 331 extends through the second mounting hole 19 and is connected to the elastic top cover 332. This structure makes the overall structure compact and reduces the size of the integrated inflation and deflation valve.
[0107] Reference Figure 2 and Figure 4 In this embodiment, the degassing assembly further includes a cover 31, which is connected to the valve body 10. At the connection between the cover 31 and the valve body 10, the edge of the elastic top cover 332 is located between the cover 31 and the valve body 10 along the second direction, so that the upper end surfaces of the cover 31 and the elastic top cover 332 along the second direction form a cavity 311 isolated from the second mounting through hole 19. The degassing assembly further includes a support seat 34, which is disposed at the upper end of the elastic top cover 332. The support seat 34 and the second elastic member 35 are both located within the cavity 311. One end of the second elastic member 35 abuts the upper end surface of the support seat 34 in the second direction, and the other end of the second elastic member 35 abuts the cover 31.
[0108] Thus, the second mounting hole 19 is connected to the gas chamber through the second channel 12, so that the gas in the gas chamber can act on the elastic top cover 332. When the pressure in the gas chamber is greater than the pressure value of the second elastic member 35, the elastic top cover 332 can drive the entire second valve core 33 to move forward in the second direction. One end of the support rod 331 is separated from the channel wall of the second channel 12 along the second direction (i.e., in the third position), and the second ventilation path is connected, so that the gas chamber is connected to the outside world to achieve pressure relief. When the pressure value in the gas chamber drops to below the pressure setting value, one end of the support rod 331 is connected to the channel wall of the second channel 12 (i.e., in the fourth position), the second ventilation path is sealed, and the pressure relief stops. Furthermore, the support rod 331 is made of plastic to ensure a certain rigidity of the second valve core 33, which is convenient for support and movement.
[0109] The elastic top cover 332 is made of a soft, deformable rubber material, providing sufficient space for the second valve core 33 to move forward in the second direction when the gas in the gas chamber pushes the second valve core 33 forward. Furthermore, the elastic top cover 332 may have an uneven surface, such as a wavy pattern. This unevenness provides more space for the second valve core 33 to move forward in the second direction over a greater distance, thereby increasing the cross-sectional area of the second ventilation path and facilitating rapid pressure relief.
[0110] Reference Figure 4 Along the first direction, the second channel 12 includes a first section 121 and a second section 122. The first section 121 communicates with the gas chamber. In the third position, the first section 121 and the second section 122 communicate with each other. In the fourth position, the first section 121 and the second section 122 are separated. Furthermore, the first section 121 and the second section 122 are stacked in the second direction. That is, the first section 121 and the second section 122 are located at different positions in the second direction and separated by a certain distance. The first section 121 and the second section 122 are connected by a connecting channel 123 extending along the second direction. This stacking arrangement facilitates sealing the second channel and provides more space for the installation and movement of the second valve core 33, allowing the second channel to switch between a sealed and open state.
[0111] In this embodiment, the degassing component 30 also includes a third sealing plate 36, which is installed on the support rod 331 and can move with the support rod 331. That is, when the gas pressure in the gas chamber is greater than the set value, the first ventilation path is in a sealed state without the action of external force, and the gas pressure acts on the elastic top cover 332 and overcomes the elastic force of the second elastic member 35, pushing the elastic top cover 332 to move forward in the second direction, while driving the support rod 331 and the third sealing plate 36 thereon to move forward in the second direction, so that the third sealing plate 36 is separated from the channel wall of the first section 121 of the second channel, the first section 121 of the second channel is connected to the second section 122 of the second channel, the second ventilation path is in a conducting state, and the gas chamber is connected to the outside world through the second channel 12 for pressure relief. When the pressure value in the gas chamber drops to less than the set value, the second elastic member 35 pushes the second valve core 33 to reverse in the second direction (such as Figure 1 and Figure 4 When the support rod 331 is moved to reset (as shown in the R direction), the support rod 331 is inserted into the connecting channel 123, the third sealing sheet 36 is sealed and connected to the channel wall of the first section 121 of the second channel, the first section 121 of the second channel and the second section 122 of the second channel are separated, so that the second ventilation path is in a sealed state and the pressure relief is stopped.
[0112] Reference Figure 2 and Figure 4 In this embodiment, the cross-sectional area of the elastic top cover 332 is larger than that of the support rod 331. Due to the large cross-sectional area of the elastic top cover 332, a second elastic member 35 with a relatively large elastic force can be used to apply a relatively large force on the elastic top cover 332 to seal the second ventilation path. The small cross-sectional area of the support rod 331, combined with the smaller cross-sectional area of the third sealing piece 36, seals the second ventilation path, making it easier for the elastic top cover 332 to push the support rod 331, allowing the third sealing piece 36 to seal the second ventilation path with a smaller cross-sectional area. Therefore, the configuration of the cross-sectional area of the elastic top cover 332 being larger than that of the support rod 331 makes it easier to close the second ventilation path after pressure relief. Since the cross-sectional area of the support rod 331 and the third sealing sheet 36 is small, the contact area with the valve body 10 when sealing the second ventilation path is small. Therefore, the mutual suction force between the third sealing sheet 36 and the valve body 10 is small, so that when pressure relief is required, the elastic top cover 332 can more easily drive the support rod 331 to move forward in the second direction, thereby opening the second ventilation path for pressure relief.
[0113] Reference Figure 4 The cavity 311 enclosed by the cover 31 and the elastic top cover 332 is in communication with the exterior of the gas chamber. For example, the valve body 10 is provided with a third channel 13 having one end in communication with the outside world, and the cover 31 is provided with a fourth channel 312 having one end in communication with the cavity 311. The fourth channel 312 is connected to the third channel 13 to form an air pressure balance channel. This air pressure balance channel ensures that the cavity 311 is always in communication with the outside world, so that the air pressure acting on the support seat 34 within the cavity 311 is always balanced with the external air pressure and does not change with changes in ambient temperature.
[0114] If the cavity 311 is a closed space, when the outside temperature rises, the gas in the cavity 311 expands due to the heat, which will form pressure on the upper surface of the support seat 34, so that the pressure (and the set pressure value) applied to the second valve core 33 becomes the sum of the pressure value provided by the second elastic member 35 and the pressure value increased due to the temperature increase. In this scenario, the air pressure in the gas chamber must be greater than the set pressure value in order to make the second valve core 33 move forward in the second direction to open the second ventilation path for pressure relief. The pressure value increased by the temperature increase changes with the temperature, which will cause the final deflated air pressure to be unstable and always change with the temperature. In this embodiment, the cavity 311 is always connected to the outside world, so the pressure acting on the upper end surface of the support seat 34 is always the same as the outside pressure and is not affected by temperature changes. Therefore, the deflated pressure is only determined by the elastic force of the second elastic member 35, which can keep the deflated pressure in a stable state.
[0115] Continue to refer to Figure 4The degassing assembly of this embodiment also includes a plug 32, which is connected to the cover body 31. The other end of the second elastic member 35 abuts against the plug 32, and the plug 32 can move relative to the cover body 31 along the second direction. Exemplarily, the plug 32 is threadedly connected to the cover body 31. When the plug 32 is rotated to move relative to the cover body 31 along the second direction, the compression amount of the second elastic member 35 along the second direction can be adjusted, thereby adjusting the pressure of the second elastic member 35 on the support seat 34, and thus adjusting the pressure relief value of the gas chamber. In another embodiment, the plug 32 may not be provided on the cover body 31, or the plug 32 is fixedly connected to the cover body 31, and the end of the second elastic member 35 directly abuts against the cover body 31 or the end of the plug 32, so that the compression amount of the second elastic member 35 is fixed, and the pressure relief value of the gas chamber remains unchanged, which is suitable for scenarios where the pressure relief value of the gas chamber does not need to be adjusted.
[0116] In summary, the integrated inflation and deflation valve in the embodiment of the present invention integrates inflation, overpressure deflation and manual exhaust, can achieve timely overpressure deflation by setting the pressure relief value, can accurately control the deflation pressure, is efficient and safe, easy to install, and has low cost, and effectively solves the problem that the appearance and life of inflatable products are affected by external factors.

One end of a first channel 11 and one end of a second channel 12 are respectively connected to the interior of the gas chamber, while the other end of the first channel 11 and the other end of the second channel 12 are respectively connected to the exterior of the gas chamber. Exemplarily, the inflatable body is an inflatable product having a gas chamber, such as a massage pool or an inflatable water ski.
