When, first the protrusion of the changer lever is switched to and is abutted with the switching valve core, to push the switching valve core displacement, and makes one second
Grooving connects hole with the efferent duct and is connected.Thus, which the gas in the cylinder just can connect mouth via the cylinder, cylinder connects hole and incite somebody to action
Second o ring is elapsed toward the direction of another second grooving, is enable gas by this one second grooving and is entered defeated in one
It after portalling, then is sent out by another delivery outlet and another second grooving, and enters back into and connect in hole in the efferent duct, to be sent to this
Outside efferent duct, so as to reaching the effect of being inflated to tire by the gas receiver, and the tire pressure, then 2 first cut by this
The setting of slot allows gas to push away first o ring toward the 2 first grooving direction, is connect via the valve core hole, then by the air gauge
Hole and be shown in the air gauge.Furthermore when being inflated to foreign object by the gas receiver, if when gas deficiency in gas receiver,
Also it can be fed gas into switching valve by the pump body, to be sent out again from the efferent duct, the effect of to carry out tonifying Qi.Institute
With the present invention can not only directly be inflated foreign object with pump body, can be also inflated to foreign object by gas receiver, to reach
Convenience on using.Moreover due to switching valve provided by the present invention and its switching valve core, construction is special and simple,
Not only action is accurate, and manufacturing cost is cheap, be not see on the market at present and.

Cylinder connects hole 204 and keeps unimpeded, thus, user is when controlling the piston rod group 12 action, the gas in the stack shell 112
It can be squeezed by piston 121 and pass through the gas injection bottom plug 115, and be sent into defeated in this via the non-return valve 13, appendix 14 again
Enter in mouth 151, feeding is made just to be input to the switching valve 22 via at least one output mouth 153 in the gas in the input mouth 151
Valve core hole 201 in, entered in the cylinder 21 (as shown in Figure 2) with allowing gas to connect hole 204 via the cylinder, with reach into
The effect of row gas storage, and due to entering in the gas in the input hole 252, from after the delivery outlet 258 submitting, can by this second
O ring 27 and third o ring 28 are pushed away toward 2 second groovings, 257 other direction so that are blocked in the output by second o ring 27
Between hole 258 and the efferent duct connect hole 206, which blocks in the rod aperture 202, and makes gas at this time can not be defeated from this
Outlet pipe 24 is sent out or is released by the rod aperture 202, to tie up the smoothness and air-tightness when gas storage, and the air pressure of the air storage chamber 211,
Then first via the valve core hole 201, then hole 205 is connect by the air gauge and is shown in the air gauge 23.
Then, when user is intended to be inflated foreign object by the gas receiver 20, first by the protrusion 294 of the changer lever 226
It switches to and is abutted with the switching valve core 222, to push 222 displacement of switching valve core, and make the second grooving of one 257 and the output
Pipe connects hole 206 and (as shown in Figure 3) is connected.Thus, which the gas in the cylinder 21 just can connect mouth 212, cylinder via the cylinder
It connects hole 204 and elapses second o ring 27 toward the direction of another second grooving 257, gas is enable one second to be cut by this
Slot 257 and enter sent out after one delivery outlet 258, then by another delivery outlet 258 and another second grooving 257, and again into
Enter the efferent duct to connect in hole 206, to be sent to outside the efferent duct 24, so as to reaching by the gas receiver 20 to tire (not shown)
The effect of being inflated, and the tire pressure allow gas by first o ring 26 then by the setting of 2 first grooving 256
It is pushed away toward 2 first groovings, 256 direction, via the valve core hole 201, then hole 205 is connect by the air gauge and is shown in the air gauge
23。
Furthermore when being inflated to foreign object by the gas receiver 20, if when gas deficiency in gas receiver 20, it also can be by this
Pump body 10 is fed gas into switching valve 22, to send out (as shown in Figure 4) from the efferent duct 24 again, to carry out tonifying Qi
Effect.
So the present invention can not only directly be inflated foreign object with pump body, also can by gas receiver to foreign object into
Row inflation uses upper convenience to reach.Moreover due to switching valve provided by the present invention and its switching valve core, construction
Special and simple, not only action is accurate, and manufacturing cost is cheap, be not see on the market at present and.

Show), the valve core column 31 is cylindrical, have a cylinder 311, an input hole 312, one first annular groove 313, one second annular groove 314,
One third annular groove 315,2 first groovings 316,2 second groovings 317 and two delivery outlets 318, the input hole 312 is from the cylinder 311
One end axially extends a predetermined depth and forms inside, which forms from the 311 circumferential surface annular recess of cylinder, this
Two annular grooves 314 are formed from the 311 circumferential surface annular recess of cylinder, the third annular groove 315 from the 311 circumferential surface annular recess of cylinder and
At, 2 first groovings 316 fly two relative position of circumferential surface from the cylinder 311 and are recessed, and 2 first groovings 316 and with the cylinder
311 one end and first annular groove 313 connection, 2 second groovings 317 from two relative position of circumferential surface of the cylinder 311 recess and
At, and 2 second groovings 317 are communicated between second annular groove 314 and the third annular groove 315, two delivery outlets 318 are respectively from each
The slot bottom of third annular groove 315 extends radially to be connected to the input hole 312, which is placed on first ring
In slot 313, which is placed in second annular groove 314 (as shown in FIG. 12 and 13).
Although the switching valve core 30 provided in the present embodiment is different from the construction of valve core is switched in previous embodiment, its
Gas storage (as shown in figure 14) can be all carried out to gas receiver 20 and gas is sent out by gas receiver 20 being mended with by pump body 10
The effect of switch between gas (such as Figure 15), is identical.
Secondly, as shown in Figure 14 and Figure 15,31 one end of valve core column also with one be in arc surface end plug portion 310, with by
Closing or open is formed between the end plug portion 310 and foreign object.
It is above to be taken off, preferred embodiment only provided by the present invention, not to limit the present invention implementation model
It encloses, all those skilled in the art should all belong to the range that the present invention is covered according to the equivalent change carried out by the present invention.
