Referring to fig. 1, 4 and 6, in the present embodiment, when in use, the air cylinder 3 may be selectively hung below the flow dividing and air controlling mechanism 2, or the air cylinder 3 may be detached. When the air cylinder 3 is hung under the flow-dividing air-controlling mechanism 2 as shown in fig. 4 and 6, the air-controlling unit 20 is located at the air storage position. That is, when the air control unit 20 is to be switched from the inflating position to the air storing position, the ejector pin 316 of the air cylinder 3 extends into the communicating channel 221 of the flow dividing seat 22, and overcomes the elastic forces of the first spring 201 and the second spring 202 to push the first air control valve 25 and the second air control valve 26 upward.
When the top edge of the choke portion 253 of the first gas control valve 25 abuts against the lower side of the shoulder surface 220 of the flow dividing seat 22, the gas entering from the communication channel 221 cannot flow to the pumping channel 225, and when the inner gas-closing ring 204 mounted on the second gas control valve 26 is separated from the outer gas-closing ring 203, the gas entering from the communication channel 221 passes through the gas control channel 250 and enters the gas inlet channel 317 of the gas cylinder 3, and finally the gas pressure pushes open the gas-closing member 322, so that the gas can enter the gas storage space 310 for storage. That is, when the gas control unit 20 is located at the gas storage position, the gas generated by the gas generating mechanism 1 cannot flow to the pumping unit 4, and only enters the gas storage space 310 through the gas control channel 250 of the first gas control valve 25 for storage.
Referring to fig. 6, 8 and 9, after the air storage is completed, as long as the sleeve 231 is rotated, not only the air storage cylinder 3 can be separated from the flow-dividing and air-controlling mechanism 2, but also the air-controlling unit 20 can be switched from the air storage position to the air inflation position, and the following three actions are automatically generated:
operation (1): the gas stored in the gas storage space 310 and the gas-closing spring 323 push up the gas-closing member 322 so as to store the high-pressure gas in the gas storage space 310.
Operation (2): when the thimble 316 of the air cylinder 3 no longer pushes the air control unit 20, the second air control valve 26 will move downwards due to the pushing of the second spring 202, and drive the inner closed air ring 204 to move downwards and then press against the outer closed air ring 203, so as to prevent the air from flowing out through the air control passage 250.
Operation (3): the first spring 201 will assist the first gas control valve 25 to descend to make the choke portion 253 leave the shoulder surface 220 of the flow dividing seat 22, so that the gas generated by the gas generating mechanism 1 can enter the communicating channel 221, flow to the inflating channel 225, and finally be sent out by the inflating unit 4, and the pressure value of the gas sent out by the inflating unit 4 is relatively low because the gas is directly generated by the gas generating mechanism 1.
When a user wants to use high pressure gas, as shown in fig. 8, the gas release pipe 342 of the gas cylinder 3 is connected to the object to be inflated, and then the gas release switch 340 is turned to switch the gas cylinder 3 to a gas release position, so that the high pressure gas stored in the gas storage space 310 can flow through the first pipe 343, the gas release passage 348, the communication hole 349, the second pipe 344, and finally the gas release pipe 342 to the object to be inflated.
As can be seen from the above description, the first embodiment of the present invention achieves the purpose of changing the gas transmission path by installing the air cylinder 3 below the flow dividing seat 22 of the flow dividing and gas controlling mechanism 2, and the structure is novel, and the air cylinder 3 can be detachably installed below the flow dividing and gas controlling mechanism 2, so as to provide different pressures of gas, and also have the efficacy of facilitating the disassembly of the air cylinder 3 and facilitating the respective use.
Referring to fig. 10, 11 and 12, a second embodiment of the pump assembly of the present invention is similar in structure to the first embodiment, and differs therefrom in that: the first embodiment is to switch the gas control unit 20 between the gas storage position and the gas pumping position automatically during the process of disassembling and assembling the gas cylinder 3, and the second embodiment is to change the automatic mode into the manual mode. In order to achieve the above object, the inflation device also includes the gas generating mechanism 1, the flow-dividing and gas-controlling mechanism 2, the gas cylinder 3 and the inflation unit 4, and the structures of the gas generating mechanism 1, the gas cylinder 3 and the inflation unit 4 are the same as those of the first embodiment.

The gas control unit 20 of this embodiment also has the first gas control valve 25, the first gas control valve 25 has a valve enclosure portion 255 rotatably installed in the installation channel 270, and a control portion 256 protruding from the installation channel 270, the valve enclosure portion 255 defines a shaft 257 and has two vent holes 258 communicating with the shaft 257, and the shaft 257 has an opening 259 spaced apart from the bottom wall 272 and adjacent to the bottom wall 272.
The air control unit 20 of this embodiment can also switch between the air pumping position and the air storage position, that is, the user can hold the operation part 256 of the first air control valve 25 by hand and rotate the first air control valve 25. As shown in fig. 13 and 14, when the air control unit 20 is located at the inflation position, one of the vent holes 258 of the first air control valve 25 is communicated with the inflation channel 225, at this time, the air entering from the air inlet channel 223 enters the axial channel 257 through the expanded pipe portion 273, and finally enters the inflation unit 4 through one of the vent holes 258 through the inflation channel 225. As shown in fig. 15 and 16, when the gas control unit 20 is located at the gas storage position, the vent 258 is aligned with the communication channel 221, and at this time, gas can pass through the first gas control valve 25 and enter the gas cylinder 3. Therefore, the second embodiment of the present invention can achieve the same creation purpose by changing the structure of the flow-dividing gas-controlling mechanism 2.
