In order to make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

Referring to FIGS. 1 to 4 , an embodiment of the present utility model discloses a gas filling and deflating integrated valve, including a valve body 10 . Specifically referring to Figures 2 and 4, a first channel 11 and a second channel 12 are provided in the valve body 10. An inflatable assembly 20 is provided on the first ventilation path of the first channel 11. The inflatable assembly 20 can be positioned relative to the first The ventilation path moves to switch between the first position and the second position. In the first position, the first ventilation path is in a conductive state; in the second position, the first ventilation path is in a sealed state. A bleed assembly 30 is provided on the second ventilation path of the second channel 12, and the bleed assembly 30 can move relative to the second ventilation path to switch between the third position and the fourth position. In the third position, the second ventilation path is in a conductive state; in the fourth position, the second ventilation path is in a sealed state.

Illustratively, the first ventilation path and the second ventilation path refer to the paths through which gas circulates in the first channel 11 and the second channel 12 respectively. For example, the first position and the third position may respectively be a determined position that enables the first ventilation path and the second ventilation path to be in a conducting state, or may be respectively capable of placing the first ventilation path and the second ventilation path in a conducting state. The specific location interval of the communication state. In this embodiment, no limitation is made.

The gas-inflating and deflating integrated valve of this embodiment is used for a first object (not shown in the figure). The first object includes a gas chamber. For example, the first object is a massage pool, an inflatable water ski or other similar devices with gas. Inflatable products for chambers. Among them, one port (such as the gas outlet) of the first channel 11 of the integrated gas filling and deflation valve and one port (such as the gas inlet) of the second channel 12 are respectively used to communicate with the inside of the gas chamber, and the first channel 11 The other port (such as the air inlet) and the other port of the second channel 12 (such as the air outlet) are respectively used to communicate with the outside of the gas chamber.

When the first ventilation path is in a conducting state and the second ventilation path is in a sealing state, the gas chamber can be inflated through the inflation-deflation integrated valve. For example, the gas can be made to enter the first channel through the other port of the first channel 11 through an inflating device, and flow to one port of the first channel 11 through the first ventilation path to enter the gas chamber, so as to realize the control of the gas chamber. Inflate the chamber.

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 inflation and deflation integrated valve. For example, after the gas chamber is inflated, when the gas pressure inside it rises (for example, when the gas temperature of the gas chamber rises due to sunlight exposure, etc.), under the action of the gas pressure, the second ventilation path is in In the conduction state, the gas in the gas chamber enters the second channel through one port of the second ventilation path, circulates in the second ventilation path, and is led to the outside of the gas chamber through the other port of the second channel to achieve gas control. The pressure relief of the chamber prevents damage to the gas chamber caused by the increase in air pressure in the gas chamber.

For example, after the gas chamber is filled with air, both the first ventilation path and the second ventilation path are in a sealed state. When the pressure in the gas chamber is too high, the first ventilation path is in a sealed state and the second ventilation path is in a conducting state, and the gas chamber is depressurized. After the gas chamber pressure relief is completed, the first ventilation path and the second ventilation path are both in a sealed state. If the air pressure in the gas chamber increases again, the first ventilation path is in a sealed state and the second ventilation path is in a conducting state, and the gas chamber is depressurized again through the second ventilation path.

That is, the integrated inflation and deflation valve of the present application integrates inflation and deflation functions, and can automatically relieve pressure in real time when the pressure in the gas chamber increases.

For example, when the inflatable device is directly pressed to make the first ventilation path in a conductive state, the gas chamber is connected to the outside world, and the gas in the gas chamber can enter through a port of the first channel and circulate through the first ventilation path. The other port of the first channel leads to the outside of the gas chamber to achieve the effect of manually depressurizing the gas chamber.

The other port moves (as shown in the E direction in Figure 4) to be in the second position. Illustratively, the external force acting on the inflatable assembly 20 includes a force exerted by a user. That is, the user can apply an external force to the inflatable component 20 (such as applying an external force by pressing the inflatable component 20 through an inflatable device), so that the inflatable component 20 moves toward one end of the first channel 11 connected with the gas chamber. When the first ventilation path is in the first position, the gas can flow from outside the gas chamber into the gas chamber to inflate the gas chamber. After stopping the application of external force to the inflatable assembly 20 (such as removing the inflatable device), the inflatable assembly 20 can move to a second position that seals the first ventilation path, blocking the flow between the inside and outside of the gas chamber, and stopping the gas chamber. Inflate.

Referring to Figures 2 and 4, in this embodiment, the inflatable assembly 20 includes a first valve core 21 and a first elastic member 25. The first valve core 21 can move in a first direction toward a port of the first channel 11 under the action of external force. , so that the first ventilation path is in a conductive state.

That is, when the gas chamber needs to be inflated, the second ventilation path is in a sealed state, and the first valve core 21 can be moved by external force (such as applying an external force to the first valve core 21 by the inflation device) to guide the first ventilation path. to inflate the inflatable chamber. After the inflation is completed, remove the external force (such as taking away the inflation device), reset the first valve core 21 through the first elastic member 25, seal the first ventilation path, and stop inflating the gas chamber. At this time, the gas chamber is isolated from the outside world and maintains a certain pressure.

The fixed part 15 divides the first channel 11 into two chambers along the first direction. The space between the fixed part 15 and one end of the first channel 11 connected with the gas chamber is the first chamber 111. The fixed part 15 and The space between the other end of the first channel 11 that communicates with the outside world is the second chamber 112 . The fixing part 15 is provided with a first mounting through hole 16 , and the stem part 212 of the first valve core 21 is disposed through the first mounting through hole 16 along the first direction.

The chamber is inflated. After the rod portion 212 loses the external force (such as taking away the inflatable 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 port of the first channel 11, so that the first The valve core is in the second position, and the first ventilation path is sealed to isolate the inflatable cavity from the outside world.

When the first ventilation path is in a sealed state, the first blocking block 213 is located in the first gap 161 and the second blocking block 214 is located in the second gap 162 .

When the first valve core 21 moves in the first direction relative to the first mounting through hole 16 toward a port of the first channel 11 , the first clamping block 213 and the second clamping block 214 follow the first valve core 21 in the first direction. Move and separate from the first gap 161 and the second gap 162 respectively. After that, the first valve core 21 can rotate in the circumferential direction (that is, an external force is applied to the first valve core 21 to cause it to rotate), so that the first blocking block 213 and the second blocking block 214 can rotate axially together (circumferentially around the first valve core 21 ). direction), respectively intersect with the first gap 161 and the second gap 162, that is, in the first direction, the first blocking block 213 does not correspond to the first gap 161, and the second blocking block 214 does not correspond to the second gap 162. Correspondingly, the first clamping block 213 and the second clamping block 214 correspond to the edge of the first mounting through hole 16 between the first notch 161 and the second notch 162 .

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 through hole 16 along the first direction. At this time, the first ventilation path In the conduction state, the gas in the gas chamber can be led to the outside through the first channel.

With this arrangement, manual deflation of the gas chamber can be achieved. That is, after manually pushing the first valve core 21 to move toward one port of the first channel 11 in the first direction, each blocking block moves out of each gap along the first direction; and then by rotating the first valve core 21, each blocking block can be The edges between the notches on the first mounting through hole 16 are snapped along the first direction. Then, the first ventilation path is opened, allowing the gas chamber to communicate with the outside world, thereby achieving the effect of manually deflating the gas chamber, and achieving the purpose of making the first object easy to carry and transport. During the deflation process, the user does not need to apply external force to the first valve core 21 all the time, making the operation more convenient and improving the user experience.

In other embodiments, the number of notches may be greater than or equal to the number of blocking blocks, and the number of notches and blocking blocks may also be greater than two.

Referring to Figures 2 and 4, and simultaneously referring to Figures 6 and 7, the inflatable assembly 20 also includes an end cap 26. The end of the end cap 26 is provided with hook-shaped snap joints 261 at intervals. The end cap 26 can be moved from the first direction along the first direction. The other port of one channel 11 is inserted into the first channel 11 (that is, loaded by the second chamber 112 of the first channel 11). Correspondingly, as shown in FIG. 7 , the mounting part is provided with a gap 151 for the clamp connector 261 , and the clamp connector 261 extends from the second chamber 112 to the first chamber 111 through the gap, and then the end cover 26 By rotating around its own axis, the clamping joint 261 can be clamped with the fixed part 15 along the first direction, as shown in FIGS. 4 and 6 , so that the end cap 26 is connected to the valve body 10 .

Continuing to refer to FIG. 4 , the inflatable assembly 20 also includes a second sealing sheet 27 , which is disposed on the end cover 26 ; when the end cover 26 is connected to the valve body 10 , the second sealing sheet 27 is in close contact with the valve body 10 , the first ventilation path can be placed in a sealed state. For example, referring to FIG. 7 , in the second chamber 112 , an annular second sealing support 18 is provided on the fixed part 15 . The second sealing support 18 is used to fit with the second sealing sheet 27 to facilitate the second sealing. The sealing piece 27 provides better sealing. Furthermore, the material of the second sealing piece 27 is silica gel, which can play a buffering role when the end cover 26 is installed. At the same time, the silica gel material is deformable to make the sealing better.

In this implementation, the first sealing piece 22 and the second sealing piece 27 achieve double sealing of the first ventilation path, which can ensure the sealing performance of the passage and prevent air leakage.

During use, when it is necessary to inflate the gas chamber of the first object, keep the second ventilation path in a sealed state, first rotate the end cap 26 to disengage the clamping joint 261 from the mounting part, and then remove the end cap 26 . After that, an external force is applied to the first valve core 21 through the inflating device to compress the first elastic member 25 so that the first valve core 21 moves in the first direction toward a port of the first channel 11. When moving to the first position, the first valve core 21 moves to the first position. The sealing piece 22 is separated from the first sealing support 17, so that the first ventilation path is in a conductive state, and the inflating device can inflate the gas chamber. After the inflation is completed, the inflation device is deactivated, and the first valve core 21 moves in the first direction toward the second chamber 112 under the action of the first elastic member 25 so that the first sealing piece 22 can be in contact with the first sealing support 17 When the gas chamber is closed, the first ventilation path is in a sealed state, and the gas chamber is isolated from the outside world. Then, insert the end cap 26 into the first channel 11 and snap it into place with the mounting part through the snap joint 261, so that the second sealing piece 27 and the second sealing support 18 fit together to achieve double sealing of the first ventilation path.

Furthermore, in this embodiment, the deflation component 30 can move relative to the second ventilation path under the action of external force to be in the third position, and the deflation component 30 can move relative to the second ventilation path after losing the external force to be in the fourth position. . Illustratively, the second channel 12 extends along a first direction, and the vent assembly 30 moves forward along the second direction (shown in the Z direction in FIGS. 2 and 4 ) under the action of external force relative to the second ventilation path ( FIGS. 2 and 4 ). (shown in direction F in Figure 4) to be in the third position; alternatively, the deflation assembly 30 can reverse direction relative to the second ventilation path in the second direction after losing the external force (shown in direction R in Figures 2 and 4) Move to be in a fourth position; wherein 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.

Both the first channel 11 and the second channel 12 extend along the first direction, which facilitates processing and minimizes the volume of the valve body. In another embodiment, the first channel 11 and the second channel 12 are not arranged in parallel.

Referring to Figures 2 and 4, the air release assembly 30 includes a second valve core 33 and a second elastic member 35. The second valve core 33 can move forward in the second direction (direction F in Figures 2 and 4) under the action of external force. (shown) moves so that the second ventilation path is in a conductive state. The second valve core 33 is elastically and sealingly connected to the valve body 10 through the second elastic member 35; the second elastic member 35 is used to reset the moved second valve core 33 so that the second ventilation path is in a sealed state. Further, the external force acting on the deflation component includes gas pressure in the gas chamber.

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 sealingly connected to the valve body 10, and when the pressure in the gas chamber is greater than the set value, the second valve core 33 can be sealed. The second valve core 33 moves forward in the second direction, so that the second ventilation path is in a conductive state, and the gas chamber communicates with the outside world for pressure relief. When the pressure value in the gas chamber drops below the pressure set value, the second valve core 33 reverses in the second direction under the action of the second elastic member 35 (as shown in the R direction in Figures 2 and 4) Move to restore the state of sealing connection with the valve body 10, so that the second ventilation path is in a sealed state, blocking the connection between the gas chamber and the outside world, and stopping pressure relief. Therefore, this embodiment can realize the automatic pressure relief of the gas chamber when the pressure is greater than the set pressure, thereby preventing the first object from being deformed due to excessive pressure in the gas chamber, thereby extending the service life of the first object. And during this process, the pressure relief pressure can be accurately controlled.

Referring to FIG. 4 , and simultaneously referring to FIG. 2 , the valve body 10 is provided with a second mounting through hole 19 extending along the second direction. The second valve core 33 includes a support rod 331 extending along the second direction and an elastic top cover 332. The support rod 331 is movably disposed in the second installation through hole 19 along the second direction. One end of the support rod 331 extends out of the second installation through hole 19 and is connected to the channel wall of the second channel 12 in a sealing manner. The other end of the support rod 331 extends out of the second installation through hole 19 and is connected to the elastic top cover 332 . Adopting this structure can make the overall structure compact and reduce the volume of the integrated gas filling and deflating valve.

Referring to Figures 2 and 4, in this embodiment, the air release assembly also includes a cover body 31, which is connected to the valve body 10. At the connection point between the cover body 31 and the valve body 10, the edge of the elastic top cover 332 is along the first The two directions are located between the cover body 31 and the valve body 10 , so that the upper end surfaces of the cover body 31 and the elastic top cover 332 along the second direction form a cavity 311 isolated from the second installation through hole 19 . The deflation assembly also includes a support seat 34. The support seat 34 is disposed on the upper end of the elastic top cover 332. The support seat 34 and the second elastic member 35 are both located in the cavity 311. One end of the second elastic member 35 and the support seat 34 are in the second position. The upper end surface of the second elastic member 35 is in contact with the cover body 31 .

Therefore, the second installation through hole 19 is connected with 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 When, the elastic top cover 332 can drive the entire second valve core 33 to move forward in the second direction, and one end of the support rod 331 is separated from the channel wall of the second channel 12 along the second direction (that is, in the third position), The second ventilation path is opened to communicate the gas chamber with the outside world to achieve pressure relief. When the pressure value in the gas chamber drops below the pressure set value, one end of the support rod 331 is connected to the channel wall of the second channel 12 (that is, in the fourth position), the second ventilation path is sealed, and pressure relief is stopped. . Furthermore, the support rod 331 is made of plastic, which ensures a certain rigidity of the second valve core 33 and facilitates support and movement.

The elastic top cover 332 is made of soft rubber and is deformable, so that the gas in the gas chamber has a certain movement space when the second valve core 33 is pushed forward in the second direction. Furthermore, the surface of the elastic top cover 332 is uneven. If it is set in a wavy shape, the uneven surface can provide more space for the movement of the second valve core 33, making it easier to move the second valve core 33 forward for a larger distance in the second direction. , which increases the conduction cross-sectional area of the second ventilation path and facilitates rapid pressure relief.

Referring to Figure 4, along the first direction, the second channel 12 includes a first section 121 of the second channel and a second section 122 of the second channel; the first section 121 of the second channel is used to communicate with the gas chamber. In the third position, the first section 121 of the second channel and the second section 122 of the second channel are connected; in the fourth position, the first section 121 of the second channel and the second section 122 of the second channel are separated. Furthermore, the first section 121 of the second channel and the second section 122 of the second channel are stacked in the second direction, that is, the first section 121 of the second channel and the second section 122 of the second channel are located at different locations in the second direction. location, with a certain distance between them. The first section 121 of the second channel and the second section 122 of the second channel are connected by a connecting channel 123 extending along the second direction. With this arrangement, the first section 121 of the second channel and the second section 122 of the second channel are stacked in the second direction, which facilitates sealing of the second channel and provides more space for the installation and movement of the second valve core 33. The second channel switches between sealing and conducting states.

In this embodiment, the deflation assembly 30 further includes a third sealing piece 36. The third sealing piece 36 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 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 along the Moving forward in the second direction, the support rod 331 and the third sealing piece 36 on it are driven to move forward in the second direction, so that the third sealing piece 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 conductive state, and the gas chamber communicates with the outside world through the second channel 12 for pressure relief. When the pressure value in the gas chamber decreases to less than the set value, the second elastic member 35 pushes the second valve core 33 to move in the second direction in the reverse direction (as shown in the R direction in Figures 1 and 4) for reset. The support rod 331 is inserted into the connecting channel 123, the third sealing piece 36 is sealingly connected with the channel wall of the first section 121 of the second channel, and the first section 121 of the second channel and the second section 122 of the second channel are separated to allow the second ventilation The path is in a sealed state and pressure relief is stopped.

Referring to FIGS. 2 and 4 , in this embodiment, the cross-sectional area of the elastic top cover 332 is larger than the cross-sectional area of the support rod 331 . Since the elastic top cover 332 has a large cross-sectional area, the second elastic member 35 with larger elastic force can be used, which can apply a relatively large force on the elastic top cover 332 to seal the second ventilation path; while the support rod 331 is small The cross-sectional area cooperates with the third sealing piece 36 of smaller cross-sectional area to seal the second ventilation path, so that the elastic top cover 332 can easily push the support rod 331 so that the third sealing piece 36 seals the second ventilation path of smaller cross-section. Therefore, The cross-sectional area of the elastic top cover 332 is larger than the cross-sectional area of the support rod 331, which can make it easier to close the second ventilation path after the pressure is released. Since the cross-sectional area of the support rod 331 and the third sealing piece 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 piece 36 and the valve body 10 is 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.

Referring to Figure 4, the cavity 311 enclosed by the cover body 31 and the elastic top cover 332 is connected to the outside of the gas chamber. Exemplarily, the valve body 10 is provided with a third channel 13 with one end connected to the outside world, and the cover body 31 is provided with a fourth channel 312 with one end connected to the cavity 311. The fourth channel 312 is connected with the third channel 13 to form Air pressure balancing channel. This air pressure balance channel allows the cavity 311 to always communicate with the outside world, so the air pressure acting on the support base 34 in the cavity 311 is always balanced with the outside air pressure and will not change with changes in ambient temperature.

If the cavity 311 is a closed space, when the outside temperature rises, the gas in the cavity 311 will heat and expand, which will form pressure on the upper surface of the support seat 34, causing the pressure (and setting) applied to the second valve core 33 to The pressure value) becomes the sum of the pressure value provided by the second elastic member 35 and the pressure value increased due to the increase in temperature. In this case, the air pressure in the gas chamber must be greater than the set pressure value before the second valve can be activated. The core 33 moves forward in the second direction to open the second ventilation path for pressure relief. The pressure value increased by the temperature rise changes with the temperature change, which will lead to the problem of the final air pressure being unstable and changing 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 size of the deflation pressure is only determined by the second elastic member 35. Determined by elasticity, the deflation pressure can be kept in a stable state.

Continuing to refer to Figure 4, the deflation assembly of this embodiment also includes a plug 32. The plug 32 is connected to the cover 31. The other end of the second elastic member 35 is in contact with the plug 32. The plug 32 can move along the second direction. Move relative to the cover 31 . For example, 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, whereby the second elastic member 35 can be adjusted to act on the support base 34 pressure, you can adjust the pressure relief value of the gas chamber. In another embodiment, the plug 32 may not be provided on the cover 31, or the plug 32 may be fixedly connected to the cover 31, and the end of the second elastic member 35 directly abuts the end of the cover 31 or the plug 32. , if the compression amount of the second elastic member 35 is fixed, the pressure relief value of the gas chamber remains unchanged, which is suitable for scenarios where there is no need to adjust the pressure relief value of the gas chamber.

In summary, the integrated inflation and deflation valve of the embodiment of the present invention integrates inflation, overpressure deflation and manual exhaust. It can realize timely overpressure deflation by setting the pressure relief value, and can accurately control the deflation air pressure with high efficiency. It is safe, easy to install, and low in cost. It effectively solves the problem of the appearance and lifespan of inflatable products being affected by external factors.
