[0002] The bottle head valve is a starting device installed on a gas cylinder, which pierces the sealing copper film of the gas cylinder with a puncture needle to release the gas in the gas cylinder. The existing bottle head valves on the market are spring-started. Before use, the puncture needle is first pushed to the highest position by a reset device. At this time, the spring is compressed to the shortest, and then a nylon fixing pin with a pull ring is plugged at the tail of the puncture needle. After removing the reset device, the puncture needle will not fall under the block of the nylon fixing pin. When in use, the reset bottle head valve is screwed onto the gas cylinder, the nylon fixing pin is pulled out forcefully, the spring resets, and the puncture needle pierces the sealing copper film of the gas cylinder under the action of the spring, and the gas in the bottle is inflated to the target through the pipeline on the bottle head valve.

[0024] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the present utility model, and are not used to limit the present utility model.

[0025] Embodiment 1

[0026] Please refer to Figure 1 -7.

[0027] An electric - integrated control bottle valve provided in this embodiment includes a valve body 13. Upper and lower threaded holes are provided on the valve body 13. The upper threaded hole is connected with an intake adapter 16, and a small nylon gasket 15 is interposed in the middle. The lower threaded hole is connected with an exhaust adapter 18, and a large nylon gasket 17 is interposed in the middle. A large sealing ring 14 for connection and sealing with an air - inflation unit (referring to the air - using device) is provided at the lower end of the valve body 13. A piston puncture needle 11 penetrates through the valve body 13. The piston puncture needle 11 in the valve body 13 is equivalent to a piston of a cylinder. Under the action of a small return spring 12, the piston puncture needle 11 is in the original position waiting to be fired. Among them, the piston puncture needle 11 is used to pierce the copper - film head in the bottle head of the gas cylinder. The gas in the gas cylinder passes through the groove 23 of the piston puncture needle 11 and rushes out from the exhaust adapter 18 and goes to the air - inflation unit through the gas pipeline.

[0028] In the embodiment of the application of the present utility model, please refer to Figure 3 And Figure 5The valve body 13 is screwed with a large-thread adapter 7 which has two internal threads on both sides. The large-thread adapter 7 is screwed with a small-thread adapter 22 which has two external threads on both sides. The other end of the small-thread adapter 22 is connected to a motor sheath 6, and a telescopic motor 5 is arranged inside the motor sheath 6. The top end of the telescopic motor 5 is fixedly connected to a motor sheath cover 3 by a countersunk head screw 4. A waterproof connector 2 and a wire 1 are arranged on the motor sheath cover 3. A fixed pin plug 19 is arranged at the bottom end of the telescopic motor 5. A piston push rod 9 is arranged inside the small-thread adapter 22. The rear end of the piston push rod 9 is in close contact with the piston puncture needle 11. A small sealing ring 10 is arranged on the piston part of the piston push rod 9, and a large return spring 8 is arranged on the piston push rod 9.

[0029] In the embodiment of the present utility model application, please refer to Figure 4 and Figure 5 。The front end of the fixed pin plug 19 is provided with a tapered head 20, and the front end of the piston push rod 9 is provided with a blooming expansion part 21. During operation, the tapered head 20 can smoothly push into the blooming expansion part 21. The cooperation between the blooming expansion part 21 and the small-thread adapter 22 is a clearance fit under normal conditions. When the tapered head 20 of the fixed pin plug 19 is inserted into the blooming expansion part 21, the blooming expansion part 21 can expand and tightly press the surrounding parts to form an interference fit.

[0030] In the embodiment of the present utility model application, please refer to Figure 3 。Small sealing rings 10 are arranged on both the piston puncture needle 11 and the piston push rod 9. The cavity between the two parts is sealed by the small sealing ring 10. When compressed air comes in from the intake adapter 16, it can push the piston puncture needle 11 to quickly press down and pierce the copper film on the gas cylinder.

[0031] For the electric integrated control bottle head valve provided in this embodiment, the connections are as follows: one end of the large-thread adapter 7 is screwed to the valve body 13, the other end of the large-thread adapter 7 is screwed to the small-thread adapter 22, and the other end of the small-thread adapter 22 is screwed to the motor sheath 6. In the initial state, the tapered head 20 of the fixed pin plug 19 is inserted into the blooming expansion part 21 of the piston push rod 9, so that the blooming expansion part 21 is forced to expand and press against the inner wall of the small-thread adapter 22, thereby overcoming the elastic force of the large return spring 8 to keep the piston push rod 9 stationary (see Figure 5 ). The piston puncture needle 11 is always under the elastic force of the small return spring 12. The piston push rod 9 is in close contact with the piston puncture needle 11.

[0032] For the electric integrated control bottle head valve provided in this embodiment, there are two ways during normal use. Please refer to Figure 1 and Figure 3 。

[0033] Pneumatic start: The compressed gas generated by the gas controller enters the valve body 13 through the air pipe and the air inlet adapter 16 on the manual-automatic integrated valve. Under the action of the small sealing ring 10, the inside of the valve is a sealed chamber. The piston puncture needle 11 moves downward under the push of the compressed gas, piercing the copper film seal head in the bottle head of the gas cylinder. The gas in the gas cylinder passes through the groove 23 of the piston puncture needle 11 and rushes out from the air outlet adapter 18, and enters the inflatable unit through the pipeline. After use, the gas controller deflates, and the piston puncture needle 11 returns to its original position under the action of the small return spring 12, that is, the electrical-integrated control bottle head valve is reset.

[0034] Wired electric control start (electric control start): Press the start switch of the power control box for 2 seconds, and the telescopic motor 5 contracts to pull out the fixed pin plug 19. Please refer to Figure 3 , Figure 4 and Figure 5 , at this time, the blooming expansion part 21 closes, and the fit with the small threaded adapter 22 changes from the original interference fit to a clearance fit. The blooming expansion part 21 of the piston push rod 9 loses friction, and the piston push rod 9 moves downward under the action of the elastic force of the large return spring 8, pushing the piston puncture needle 11 to pierce the copper film seal head in the bottle head of the gas cylinder. The gas in the gas cylinder rushes out from the air outlet adapter 18 through the groove of the piston puncture needle 11 and enters the inflatable unit through the pipeline. After use, it is necessary to remove the valve body 13, use the reset device to compress the large return spring 8 and the piston push rod 9 to their original positions, then press the reset switch of the power control box for 2 seconds to make the telescopic motor 5 extend to plug the fixed pin plug 19 at the tail of the piston push rod 9 for fixation, remove the reset device, the piston push rod 9 does not fall, and finally install the valve body 13 back to its original position, that is, the electrical-integrated control bottle head valve is reset.

[0035] In the prior art, since the existing bottle head valves cannot be linked in multiple numbers, although the pull rings of multiple bottle head valves can be tied together for use, the reliability and opening synchronization cannot be guaranteed. In the embodiments of the present utility model application, please refer to Figure 7 , the gas controller 24 is respectively connected to the air inlet adapters 16 of three sets of electrical-integrated control bottle head valves through three air inlet manifolds 25 to achieve multiple linkages and ensure the opening synchronization. The principle of the wired electric control start is the same, that is, several sets of electrical-integrated control bottle head valves are controlled by several wires.

[0036] The beneficial effects of the present utility model are as follows: This new structure has two usage methods: pneumatic control and wired electric control.

[0037] Among them, pneumatic control is to push the internal piston puncture needle 11 from the air inlet adapter 16 with compressed air, and the piston puncture needle 11 moves downward to pierce the copper film on the gas cylinder, releasing the gas in the bottle.

[0038] Wired control is that an electric current passes through the telescopic motor 5 to retract, releasing the compressed large return spring 8. Under the action of the large return spring 8, the piston push rod 9 pushes the piston puncture needle 11 to pierce the copper film on the gas cylinder and release the gas in the cylinder.

[0039] Pneumatic control can be achieved through a long air pipe, and wired control can be achieved through a long wire 1 to realize remote control. The pneumatic control of the solenoid valve and the circuit control are both prior arts and will not be elaborated here.
