Description

Optional cylinder inflation or manual pumping

This creation mainly reveals an inflator, especially an inflator that can be inflated or manually inflated.

Please refer to the patent application No. 530884 of the Chinese Patent No. 530884, which is a pump that can be inflated by a gas cylinder or a manual method. The utility model relates to an air pump, which comprises a joint for connecting a gas nozzle, and a joint connecting the body and the seat. The body is provided with a valve chamber, and the seat body passes through the valve chamber to the rear end of the seat body through a gas cylinder inlet hole and a manual air inlet hole, and an air outlet hole is connected between the valve chamber and the joint; a pressure button is arranged in the valve seat. It is normally pushed by a resilient member to a first position, so that the manual air inlet hole and the air outlet hole communicate with each other through the valve chamber, but the gas cylinder air inlet hole cannot be connected to the air outlet hole, and the pressure button can be pressed by the external force. a second position, the gas cylinder inlet hole and the air outlet hole are connected; the rear end of the seat body is coupled with a fixed cylinder tube, and the inside thereof can accommodate a gas cylinder connected with the gas cylinder outlet hole; a movable cylinder tube, a sleeve It is arranged outside the fixed cylinder tube and can drive air into the fixed cylinder tube during reciprocating displacement.

However, when the pump having the above structure needs to be replaced with a high-pressure gas cylinder, the operation of replacing the high-pressure gas cylinder must be performed after the pump is disassembled, which is very inconvenient, and the cylinder must be assembled after the cylinder replacement is completed. Improperly, it is easy to produce a situation in which the pump is not airtight, or the assembly is easily disassembled after repeated assembly and disassembly operations, and the wear of the parts is likely to occur, and the air can be easily prevented from being airtight. In addition, cylinder inflation may not be used frequently for some users, but because the position of the high-pressure cylinder is inside the pump, the volume of the pump cannot be reduced, so that the user clearly uses the high voltage. The gas cylinder is inflated, but it must carry a large volume of air pump.

Please continue to refer to FIG. 4 and FIG. 5, which is a state diagram of the use state when the pump is selected for gas cylinder inflation or manual pumping. When the pump 10 is in use, the user can choose to use manual air pumping or use a high pressure gas cylinder for rapid inflation. When the user wants to use the manual method to inhale, the gas nozzle of the tire needs to be connected to the first seat 20 first. An air outlet 22, the user holds the outer tube 31 with one hand and the other hand operates the piston rod 32 to reciprocate, the piston head 321 can squeeze the air in the compression space 317 and push it to the first The air outlet 22 has completed the pumping action.

When the air nozzle of the tire is a French air nozzle, the user has to face the side of the abutting member 221 having the doping recess 225 toward the outside of the first air outlet 22, and the French air nozzle can be accommodated in the doffer groove 225. In the middle, the pump 10 is applied to a French air nozzle. If the air nozzle of the tire is an American air nozzle, the user must have the side of the top member 221 having the top flange 224 facing the outer side of the first air outlet 22, and the top flange 224 can abut the American style. The thimble in the nozzle allows the gas to enter the tire smoothly.

Please continue to refer to FIG. 6 to FIG. 8 , which is a state diagram of the use state of the gas cylinder when the cylinder is inflated or manually pumped. When the user selects to inflate with a high-pressure gas cylinder, the gas nozzle of the tire is first connected to the second air outlet 25 of the headstock 20, and the high-pressure gas cylinder is screwed into the screw socket of the cylinder socket 241. The portion 245, until the cylinder contacts the top member 242, and further rotates, the tip portion 246 of the top member 242 can puncture the sealing mouth of the high pressure gas cylinder to allow high pressure gas to flow out, and the high pressure gas can pass through the venting hole 247 and The second flow path 26 flows to the second air outlet 25 to complete the inflation action. Since the gas pressure that the high-pressure gas cylinder can provide is extremely high, the user only needs to put the gas nozzle into the second air outlet 25, and the air pump 10 can complete the inflation operation regardless of the American air nozzle or the French air nozzle.

Since the air pump 10 has the first flow path 23 and the second flow path 26 at the same time, the air pump can be used for the user to select manual air pumping or gas cylinder inflation according to the situation, thereby increasing the economic benefit of the air pump 10 . Since the first flow path 23 and the second flow path 26 of the pump 10 are not in communication with each other, whether the user selects manual airing or cylinder inflation, the flow paths of the two do not interfere with each other, and the use of the pump 10 is increased. Convenience. Moreover, since the cylinder receiving seat 241 is fixedly connected to the headstock 20, after the high-pressure gas cylinder is screwed to the cylinder receiving seat 241, no additional adjustment is required, so that the preparation work of the pumping cylinder 10 can be completed very quickly. To quickly inflate. Also, since the pump 10 has the top member 242, the pump 10 can be simultaneously applied to at least two different types of nozzles, increasing the applicability of the pump 10.

As far as the above is concerned, it can be concluded that this creation has the following advantages:

1. For the creation of a cylinder that can be inflated or manually pumped, the pump includes a headstock and a filling device. The headstock includes a first air inlet and a first air outlet. Forming a first flow passage between the first air inlet and the first air outlet, the first flow passage is connected to the first air inlet and the first air outlet, and the head seat further includes a second air inlet and a second air outlet a gas passage, the head seat forms a second flow path between the second air inlet and the second air outlet, and the second flow channel communicates with the second air inlet and the second air outlet, the first flow path and the second flow path are not mutually Connected, the head seat is provided with a cylinder receiving seat at the second air inlet, the cylinder receiving seat is fixedly connected to the head seat, the filling device comprises an outer tube and a piston rod, and the outer tube comprises a first end and a second end, the first end of the outer tube is connected to the first air inlet of the head seat, the outer tube is further provided with a compression space between the first end and the second end, and a piston head is provided at one end of the piston rod One end of the piston rod extends through the second end of the outer tube into the compression space, and the piston head is disposed at In the constricted space, the end of the piston rod away from the piston head protrudes out of the compression space, and the pump has the first flow path and the second flow path at the same time, so that the pump can be used for the user to select manual air pump or gas cylinder inflation according to the situation. The economic benefits of the pump.
