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

Referring to fig. 1 to 4, an embodiment of the present invention discloses an air charging and discharging integrated valve, which includes a valve body 10. Referring specifically to fig. 2 and 4, a first passage 11 and a second passage 12 are provided in the valve body 10, and an inflation assembly 20 is provided on a first ventilation path of the first passage 11, the inflation assembly 20 being 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 a conducting state; in the second position, the first vent path is in a sealed state. A bleed assembly 30 is provided on the second vent path of the second passage 12, the bleed assembly 30 being movable relative to the second vent path to switch between a third position and a fourth position. At the third position, the second air passage is in a conducting state; in the fourth position, the second vent path is in a sealed state.

Exemplarily, the first and second vent paths refer to paths through which gas circulates in the first and

second passages

11 and 12, respectively. For example, the first position and the third position may be respectively a determined position at which the first ventilation path and the second ventilation path are in a conducting state, or may be a specific position interval at which the first ventilation path and the second ventilation path are respectively in a conducting state. This embodiment is not limited to this.

The inflation and deflation integrated valve of the present embodiment is used for a first object (not shown) comprising a gas chamber, illustratively a massage sink, inflatable ski or other similar inflatable product having a gas chamber. Wherein, a port (such as the gas outlet) of the first channel 11 and a port (such as the gas inlet) of the second channel 12 of the inflation and deflation integrated valve are respectively used for being communicated with the inside of the gas chamber, and the other port (such as the gas inlet) of the first channel 11 and the other port of the second channel 12 (such as the gas outlet) are respectively used for being communicated 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 cavity can be inflated through the inflation and deflation integrated valve. Illustratively, the inflation of the gas chamber may be achieved by the inflator passing gas into the first channel from the other port of the first channel 11 and into the gas chamber via the first vent path, communicated to one port of the first channel 11.

When the first ventilation path is in a sealing state and the second ventilation path is in a conducting state, the gas cavity can be deflated through the inflation and deflation integrated valve. For example, after the gas chamber is inflated, when the pressure of the gas in the gas chamber is increased (for example, when the temperature of the gas chamber is increased due to exposure to sunlight, etc.), under the action of the gas pressure, the second ventilation path is in a conduction state, the gas in the gas chamber enters the second channel from one port of the second ventilation path, circulates in the second ventilation path, and is led to the outside of the gas chamber from the other port of the second channel, so that the pressure relief of the gas chamber is realized, and the gas chamber is prevented from being damaged due to the increase of the gas pressure in the gas chamber.

Illustratively, the first and second vent paths are both in a sealed state after inflation of the gas chamber is complete. When the pressure in the gas chamber is overlarge, the first ventilation path is in a sealing state, the second ventilation path is in a conduction state, and the gas chamber is decompressed. After the pressure relief of the gas cavity is completed, the first ventilation path and the second ventilation path are in a sealing state. If the air pressure in the air chamber rises again, the first ventilation path is in a sealing state and the second ventilation path is in a conducting state, and the air chamber is decompressed again through the second ventilation path.

That is, the integral type valve that fills and loses heart of this application has integrateed and has aerifyd and lose heart function to when pressure risees in gas chamber, can carry out real-time automatic pressure release.

For example, when the inflator is directly pressed to enable the first ventilation path to be in a conduction state, the gas chamber is communicated with the outside, and then gas in the gas chamber can enter from one port of the first channel and is communicated to the other port of the first channel through the first ventilation path to the outside of the gas chamber, so that the effect of manually relieving the pressure of the gas chamber is achieved.

With continued reference to FIG. 4, in this embodiment, the first passageway 11 extends in a first direction (shown as direction X in FIG. 4), and the inflation assembly 20 is capable of moving in the first direction relative to the first vent path toward a port of the first passageway 11 (shown as direction D in FIG. 4) under an external force to assume a first position; alternatively, the inflation assembly 20 can be moved in a first direction relative to the first vent path toward the other port of the first channel 11 (as shown in direction E in fig. 4) to assume the second position after the external force is lost. Illustratively, the external force acting on the inflation assembly 20 comprises a user-applied force. That is, the user may move the inflation assembly 20 toward the end of the first passageway 11 in communication with the gas chamber by applying an external force to the inflation assembly 20 (e.g., by pressing the inflation assembly 20 against the inflator to apply the external force), and when moving to the first position enabling the first vent path to be open, gas may flow from outside the gas chamber into the gas chamber to inflate the gas chamber. After application of external force to inflatable assembly 20 is stopped (e.g., the inflator device is removed), inflatable assembly 20 can be moved to a second position that seals the first vent path, blocking communication between the interior and exterior of the gas chamber, and stopping inflation of the gas chamber.

Referring to fig. 2 and 4, the inflation assembly 20 in this embodiment includes a first valve core 21 and a first elastic member 25, and the first valve core 21 is movable in a first direction toward a port of the first passage 11 by an external force to place the first vent path in a conductive state. The first valve core 21 is elastically connected with the valve body 10 through a first elastic piece 25; the first elastic member 25 serves to restore the moved first valve spool 21 so that the first vent path is in a sealed state. That is, when the gas chamber needs to be inflated, the second air passage is in a sealed state, and the first valve element 21 can be moved by an external force (for example, the external force is applied to the first valve element 21 by pressing the first valve element by the inflating device) to conduct the first air passage, so as to inflate the inflating chamber. After the inflation is finished, the external force is removed (for example, the inflator is taken away), the first valve core 21 is reset through the first elastic element 25, the first ventilation path is sealed, and the inflation of the gas chamber is stopped. At this time, the gas chamber is isolated from the outside and is kept under a certain pressure.

Referring to fig. 5, the first spool 21 includes a spool head 211 and a rod portion 212 connected to the spool head 211.

Referring to fig. 6 and 7, and also to fig. 4, a fixing portion 15 is provided in the first passage 11 for mounting the inflator assembly 20. The fixing portion 15 extends in the second direction, and an edge thereof is sealingly connected to an inner wall of the first passage 11. The fixing portion 15 divides the first passage 11 into two chambers along a first direction, a space between the fixing portion 15 and one end of the first passage 11 communicating with the gas chamber is a first chamber 111, and a space between the fixing portion 15 and the other end of the first passage 11 communicating with the outside is a second chamber 112. The fixing portion 15 is provided with a first mounting through hole 16, and the rod portion 212 of the first valve body 21 is provided to penetrate the first mounting through hole 16 in the first direction. The valve cartridge head 211 is positioned in the first chamber 111 and the stem 212 slidably extends through the first mounting through-hole 16 to the second chamber 112. The first elastic member 25 is sleeved on the rod portion 212 extending into the second chamber 112, one end of the first elastic member 25 abuts against the fixed portion 15, and the other end of the first elastic member 25 abuts against the end of the first valve element 21.

In this embodiment, when the rod portion 212 of the first valve element 21 is moved toward one port of the first channel 11 in the first direction by an external force (for example, the external force is applied by the inflator pressing the end portion of the rod portion 212), that is, when the valve element head 211 moves away from the fixing portion 15, the first elastic element 25 is compressed in the first direction, the first valve element 21 is in the first position, and the first ventilation path is conducted, so that the gas chamber can be inflated. After the rod portion 212 loses the external force (for example, when the inflator is taken away), the first elastic element 25 is reset, and the elastic force thereof drives the first valve core 21 to move towards the other port of the first channel 11 along the first direction, so that the first valve core is located at the second position, the first ventilation path is sealed, and the inflation cavity is isolated from the outside.

Illustratively, the inflation assembly 20 further includes a spool cap 23, the spool cap 23 is disposed at an end of the rod portion 212 of the first spool 21, and the other end of the first elastic element 25 abuts against an end surface of the spool cap 23. The spool cap 23 may facilitate installation of the first spool 21 and the first elastic member 25.

With continued reference to fig. 4 and with additional reference to fig. 6, in the first chamber 111, the fixing portion 15 is provided with a first seal support 17 in a ring shape protruding in the first direction. The inflation assembly 20 further includes a first sealing sheet 22, the first sealing sheet 22 is clamped in a groove of the head portion 211 of the first valve core 21, and the first sealing sheet 22 can move along with the first valve core 21.

In this embodiment, the second ventilation path is in a sealed state, and an external force acts on the rod portion 212 (for example, the external force is applied to the rod portion 212 by pressing the end portion of the rod portion 212 with the inflator), so that the first direction of the first valve element 21 moves toward one end of the first channel 11, that is, when the valve element head portion 211 moves away from the fixing portion 15, the first sealing sheet 22 is separated from the first sealing support 17, so that the first ventilation path is in a conducted state, and the gas chamber is communicated with the outside, and the gas chamber can be inflated. After the external force is removed (for example, the inflator is taken away), the first valve core 21 moves towards the second chamber 112 along the first direction under the action of the first elastic element 25, that is, the valve core head 211 moves towards the fixing part 15, so that the first sealing sheet 22 can be attached to the first sealing support 17, the first ventilation path is in a sealed state, the gas chamber is separated from the outside, and the inflation is stopped.

Further, the material of second gasket 27 is silica gel, can play the cushioning effect when end cover 26 installs, and its silica gel material deformable makes the leakproofness stronger simultaneously.

In this embodiment, the first sealing piece 22 and the second sealing piece 27 realize double sealing of the first ventilation path, so that the sealing performance of the passage can be ensured, and air leakage can be prevented.

In use, when the gas chamber of the first object needs to be inflated, the second gas passage is kept in a sealed state, and the end cap 26 is rotated to detach the bayonet joint 261 from the mounting portion, and the end cap 26 is removed. Then, an external force is applied to the first valve element 21 by the inflator to compress the first elastic member 25, so that the first valve element 21 moves toward one port of the first passage 11 in the first direction, and when the first valve element moves to the first position, the first sealing sheet 22 is separated from the first sealing support 17, so that the first ventilation path is in a conduction state, and the inflator can inflate the gas chamber. After the inflation is completed, the inflation device is removed, the first valve core 21 moves towards the second chamber 112 along the first direction under the action of the first elastic piece 25, so that the first sealing sheet 22 can be attached to the first sealing support 17, the first ventilation path is in a sealing state, and the gas chamber is isolated from the outside.

When the pressure value in the gas chamber is decreased to be lower than the pressure set value, the second valve core 33 moves reversely (as shown in R direction in fig. 2 and 4) along the second direction under the action of the second elastic element 35, and restores the state of being hermetically connected with the valve body 10, so that the second vent path is in a sealed state, the connection between the gas chamber and the outside is blocked, and the pressure relief is stopped. Therefore, the embodiment can realize automatic pressure relief of the gas chamber when the pressure of the gas chamber is higher than the set pressure, and realize the effect of preventing the first object from being deformed due to too high pressure of the gas chamber, so as to prolong the service life of the first object. In addition, the pressure relief pressure can be accurately controlled in the process.

The second spool 33 includes a support rod 331 extending in the second direction and an elastic cap 332, and the support rod 331 is movably disposed in the second mounting through hole 19 in the second direction. One end of the supporting rod 331 extends out of the second mounting through hole 19 to be connected with the channel wall of the second channel 12 in a sealing manner, and the other end of the supporting rod 331 extends out of the second mounting through hole 19 to be connected with the elastic top cover 332. By adopting the structure, the integral structure is compact, and the volume of the air charging and discharging integrated valve is reduced.

Referring to fig. 2 and 4, in this embodiment, the run-flat assembly further includes a cover 31, the cover 31 is connected to the valve body 10, and an edge of the elastic cap 332 is located between the cover 31 and the valve body 10 along the second direction at a position where the cover 31 is connected to the valve body 10, so that the cover 31 and an upper end surface of the elastic cap 332 along the second direction enclose a cavity 311 isolated from the second mounting through hole 19. The run-flat subassembly still includes supporting seat 34, and supporting seat 34 sets up in the upper end of elasticity top cap 332, and supporting seat 34 all is located cavity 311 with second elastic component 35, and the one end of second elastic component 35 and supporting seat 34 are in the butt of the up end of second direction, and the other end and the cover body 31 butt of second elastic component 35.

From this, second installation through-hole 19 is linked together through second passageway 12 and gas chamber to make the gas in the gas chamber can act on elasticity top cap 332, when the pressure value that the indoor pressure of gas chamber is greater than second elastic component 35, can make elasticity top cap 332 drive whole second valve core 33 and remove along the second direction forward, the one end of bracing piece 331 is separated (promptly, is in the third position) along the passageway wall of second direction and second passageway 12, the second air path switches on, make gas chamber and external world communicate with each other and realize the pressure release. When the pressure value in the gas chamber drops below the set pressure value, one end of the support rod 331 is connected to the channel wall of the second channel 12 (i.e., at the fourth position), the second channel is sealed, and the pressure relief is stopped. Furthermore, the supporting rod 331 is made of plastic, so as to ensure a certain rigidity of the second valve element 33, thereby facilitating the supporting and moving.

The material of elasticity top cap 332 is the flexible glue, and the flexible is convenient for gaseous indoor second case 33 of gaseous and possess certain removal space when jacking along the second direction positive. Further, elasticity top cap 332 surface unevenness, if set up to the wavy, unevenness can provide more spaces for the removal of second case 33, is convenient for remove second case 33 along second direction forward great distance, makes the second gas path switch on the sectional area increase, is convenient for realize quick pressure release.

Referring to fig. 4, in the first orientation, the second channel 12 includes a second channel first section 121 and a second channel second section 122; the second channel first section 121 is adapted to communicate with the gas chamber. In the third position, the second channel first section 121 and the second channel second section 122 are in communication; in the fourth position, the second channel first section 121 is isolated from the second channel second section 122. Further, the second channel first segment 121 and the second channel second segment 122 are stacked in the second direction, that is, the second channel first segment 121 and the second channel second segment 122 are located at different positions in the second direction, and are spaced apart from each other by a certain distance. The second channel first section 121 and the second channel second section 122 are communicated by a connecting channel 123 extending in the second direction. With this arrangement, the first section 121 and the second section 122 are stacked in the second direction, so as to seal the second passage, and provide more space for installing and moving the second valve spool 33, so that the second passage can be switched between the sealed state and the conducting state.

In this embodiment, the air leakage assembly 30 further includes a third sealing strip 36, and the third sealing strip 36 is mounted on the supporting rod 331 and can move along with the supporting rod 331. That is, when the gas pressure in the gas chamber is greater than the set value, the first ventilation path is in the sealed state under no external force, the gas pressure acts on the elastic top cap 332 and overcomes the elasticity of the second elastic element 35, push the elastic top cap 332 to move along the second direction positive direction, simultaneously drive the support rod 331 and the third sealing piece 36 thereon to move along the second direction positive direction, separate the third sealing piece 36 from the channel wall of the first section 121 of the second channel, the first section 121 of the second channel is communicated with the second section 122 of the second channel, the second ventilation path is in the conducted state, the gas chamber is communicated with the outside through the second channel 12, and the pressure relief is performed. When the pressure value in the gas chamber is reduced to be smaller than the set value, the second elastic element 35 pushes the second valve core 33 to move reversely (as shown in the direction R in fig. 1 and 4) along the second direction for resetting, so that the support rod 331 is inserted into the connecting channel 123, the third sealing piece 36 is hermetically connected with the channel wall of the first section 121 of the second channel, the first section 121 of the second channel is isolated from the second section 122 of the second channel, the second channel is in a sealed state, and the pressure relief is stopped.

Referring to fig. 2 and 4, in the present embodiment, the sectional area of the flexible cap 332 is larger than that of the supporting rod 331. Because the sectional area of the elastic top cover 332 is large, the second elastic member 35 with larger elasticity can be adopted, and the second air passage can be sealed by applying a larger force on the elastic top cover 332; and the small sectional area of the supporting rod 331 is matched with the third sealing sheet 36 with a smaller sectional area to seal the second ventilation path, so that the elastic top cover 332 can easily push the supporting rod 331, and the third sealing sheet 36 can seal the second ventilation path with a smaller section, therefore, the sectional area of the elastic top cover 332 is larger than that of the supporting rod 331, and the effect of closing the second ventilation path more easily after pressure relief is finished can be realized. And because the sectional area of bracing piece 331 and third gasket 36 is little, then the area of its sealed second path of ventilating with valve body 10 contact is just little, consequently, mutual suction between third gasket 36 and the valve body 10 is just little for when needing the pressure release, elastic top cap 332 can be easier drive bracing piece 331 and move along the second direction positive, and then switch on the second path of ventilating and carry out the pressure release.

Referring to fig. 4, the cavity 311 enclosed by the cover 31 and the elastic top cover 332 communicates with the outside of the gas chamber. Illustratively, a third channel 13 with one end communicated with the outside is arranged on the valve body 10, a fourth channel 312 with one end communicated with the cavity 311 is arranged on the cover 31, and the fourth channel 312 is communicated with the third channel 13 to form an air pressure balancing channel. The air pressure balancing channel enables the cavity 311 to be always communicated with the outside, so that the air pressure acting on the supporting seat 34 in the cavity 311 is always kept balanced with the outside air pressure and cannot be changed along with the change of the environmental temperature.

If the cavity 311 is a closed space, when the external temperature rises, the gas in the cavity 311 expands due to heating, and forms a 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 rise of the temperature, and under this situation, the gas pressure in the gas cavity must be greater than the set pressure value, so that the second valve core 33 can move forward along the second direction to open the second gas passage for pressure relief. The pressure value increased by the temperature rise changes along with the temperature change, so that the problem that the final air leakage pressure is unstable and always changes along with the temperature change is caused. In the embodiment, the cavity 311 is always communicated with the outside, and the pressure acting on the upper end surface of the supporting seat 34 is always the same as the outside pressure and is not affected by the temperature change, so the magnitude of the air release pressure is determined only by the elastic force of the second elastic element 35, and the air release pressure can be in a stable state.

With continued reference to fig. 4, the venting assembly of this embodiment further includes a plug 32, the plug 32 is connected to the housing 31, the other end of the second elastic element 35 abuts against the plug 32, and the plug 32 can move relative to the housing 31 along a second direction. Illustratively, the plug 32 is threadably coupled to the housing 31. When the plug 32 is rotated to move relative to the housing 31 in the second direction, the amount of compression of the second elastic member 35 in the second direction can be adjusted, so that the pressure applied to the supporting seat 34 by the second elastic member 35 can be adjusted, and the pressure relief value of the gas chamber can be adjusted. In another embodiment, the end cap 32 may not be disposed on the cover 31, or the end cap 32 is fixedly connected to the cover 31, and an end of the second elastic member 35 directly abuts against the end of the cover 31 or the end of the end cap 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 a situation that the pressure relief value of the gas chamber does not need to be adjusted.

To sum up, the utility model discloses fill integrative valve that loses heart will aerify and lose heart and manual exhaust collection in an organic whole with the excessive pressure, the accessible is set for the pressure release value and is realized that timely excessive pressure is lost heart, but the disappointing atmospheric pressure of accurate control, high-efficient safety and simple installation, and is with low costs, and effectual having solved inflatable body class product leads to its appearance and the problem that the life-span received the influence because external factor.
