143 is mobile, and the movement of push plate 143 allows toggle switch 124 thereon to encounter the protrusion 1233 on pump housing cover board 123, from
And it is touched and started pump or reversely touched and closed and pump by the protrusion 1233 by the protrusion 1233.
Based on above structure, air flue switching device forms linkage mechanism between pump housing cover board and toggle switch 124.
As shown in Figure 3a and Figure 3b shows, when needing internal pump to be inflated, rotation knob 141 to first position (is filled
Gas position), the rotation of knob 141 drives the rotation for being attached thereto gear 142 together, thus make to match with gear 142
Push plate 143 is laterally (such as to the right) mobile, and the toggle switch 124 in push plate 143 is touched by the protrusion 1233 on pump housing cover board 123
It is dynamic, so that pump is activated start-up operation, meanwhile, push plate 143 moves right so that a pair of of baffle 1432 and 1433 moves right
Dynamic, baffle 1433 is to push the first valve rod assembly to move right, so that the first blow vent is opened, at this point, push plate 143 is to the right
The first upper cover mouth 1231 that is mobile or obtaining pump housing cover board opens (the second upper cover mouth 1232 is closed at this time), forms opening 111
To the inflation air flue of 1231 to the first blow vent of the first upper cover mouth.Specifically, as illustrated by the arrow in fig. 3, fluid is from opening
Mouth 111 enters, and the first upper cover mouth 1231 that the channel defined by connection component 13 simultaneously passes through pump housing cover board enters accommodating cavity
In room, fluid is entered by the first hole 1521 of pump cover in the inner space of pump cover 152, is pressurizeed by the rotation of impeller 151,
It is flowed out again by the second hole 1522 of side from the inside of pump cover, in the air flue defined into partition 144, then from first
Blow vent 121 flows out.
As shown in figures 4 a and 4b, when needing internal pump to be deflated, rotation knob 141 to the second position (is put
Gas position), the rotation of knob 141 drives the rotation for being attached thereto gear 142 together, thus make to match with gear 142
Push plate 143 is laterally (such as to the left) mobile, and the toggle switch 124 in push plate 143 is touched by the protrusion 1233 on pump housing cover board 123
It is dynamic, so that pump is activated start-up operation, meanwhile, push plate 143 is moved to the left so that the equal Xiang Zuoyi of a pair of of baffle 1432 and 1433
Dynamic, baffle 1432 is to push the second valve rod assembly to be moved to the left, so that the second blow vent is opened, at this point, push plate 143 is to the left
The second upper cover mouth 1232 that is mobile or obtaining pump housing cover board opens (the first upper cover mouth 1231 is closed at this time), forms opening 111
To the deflation air flue of 1232 to the second blow vent of the second upper cover mouth.Specifically, as shown in the arrow in Fig. 4 a, fluid is from
Two blow vents 122 enter in chamber resettling, and the first hole 1521 by pumping cover enters in the inner space of pump cover 152, logical
The rotation pressurization of impeller 151 is crossed, then is flowed out by the second hole 1522 of side from the inside of pump cover, is defined into partition 144
The channel in air flue out, then passing through the first upper cover mouth 1231 of pump housing cover board, and being defined by connection component 13, from opening
Mouth 111 flows out.
When stopping being inflated or deflating, rotation knob 141 to first position (i.e. inflation position) and the second position (are put
Gas position) between, at this point, push plate 143 is located at centre, the toggle switch 124 in push plate 143 is by the protrusion on pump housing cover board 123
1233 are touched, so that pump stops working, meanwhile, the position of push plate 143 also turns off the first upper cover mouth 1231 of pump housing cover board
With the second upper cover mouth 1232, and since a pair of of baffle 1432 and 1433 is also at middle position, the first valve rod assembly and second
Valve rod assembly is not pushed, since the effect reset of spring blocks the first blow vent 121 and the second blow vent 122 to close first
Blow vent 121 and the second blow vent 122.At this point, air flue switching device closes air flue, and it is both non-aerating or do not deflate, such as Fig. 5 institute
