Specific embodiment
With reference to specific embodiment, this utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than restriction scope of the present utility model.In addition, it is to be understood that in the content for having read this utility model instruction
Afterwards, those skilled in the art can be made various changes or modifications to this utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment of the present utility model is related to a kind of inflator pump of employing taper valve block, as Figure 1-5, including the pump housing
1st, air valve plate 2 and air inlet and outlet end panel 3, the inside of the described pump housing 1 are vertically arranged the piston rod 6 of up and down motion, should
The upper end of piston rod 6 is provided with eccentric 5 in installing endoporus, and the eccentric 5 is connected with the motor of outside, described piston rod 6
Lower end the leather cup 7 that periphery is close to side wall is installed, described air valve plate 2 is arranged on the lower end of the pump housing 1, and described enters
It is provided with through hole on outlet valve plate 2 side by side, around two through holes, has been evenly arranged several air inlets 14 and steam vent 13 respectively,
The upper end of described air inlet 14 is disposed with air inlet valve pool 12 of the bottom surface in taper seat, is provided with and is inserted in the air inlet valve pool 12
The air-intake valve plate 10 in through hole and covering air inlet 14, the lower end of described steam vent 13 are disposed with row of the bottom surface in taper seat
Air valve groove 11, is provided with described aerofluxuss valve pool 11 and is inserted into the exhaust valve plate 9 in through hole and covering steam vent 13, described
Air inlet and outlet end panel 3 in be disposed with the inlet chamber of the corresponding discharge chamber 16 of air inlet 14 and steam vent 13 and lateral opening hole
17, the side wall of described air inlet and outlet end panel 3 is provided with the exhaust connection 4 communicated with discharge chamber 16.
Outside motor is converted into piston rod 6 by rotating shaft band 5 quick rotation of movable eccentric wheel, 5 quick rotation of eccentric
Move up and down, realization draws air into and discharges gases at high pressure, leather cup 7 can guarantee that the bottom of piston rod 6 and air valve plate 2
Between form closed space.
