Abstract
The utility model relates to an inflator, especially relates to a bidirectional air-in air-out inflator, and a technical scheme comprises an inflator body, an inflator sealing cover, a pull bar and a piston, a top of the inflator body is provided with the inflator sealing cover, and the pull bar and the piston are arranged in the inflator body, the inflator is characterized in that a bottom of the inflator body is provided with a valve B and a valve C, a upper portion of the inflator body is provided with a valve A and a valve D, the valve A, the valve B, the valve C and the valve D are all provided with a spring and a steel ball, the valve B is connected with an air exit pipe, and the valve A and the air exit pipe are connected through a rubber pipe; and beneficial effects are that the bidirectional air-in air-out inflator can greatly reduce pumping time, two times pumping can be completed by one pulling, pumping efficiency is increased, height of the inflator can be effectively reduced, because an enclosed space is formed inside the inflator, air leakage is reduced, and pumping efficiency is improved.
Description
One, technical field
The utility model relates to a kind of pump, particularly a kind of bidirection air intake pump of giving vent to anger.
Two, background technique
General Universal inflating cylinder is one-way air inlet, unidirectional pump of giving vent to anger, and pressure-raising once can only once be inflated.Between the piston of pump and barrel, the space is arranged, the rubber cup to fovea superior is arranged on piston, when carrying the cylinder of taking offence and rise, the volume of air in the air cavity of piston top increases, and pressure reduces, valve closing, and gas enters piston top air cavity along the rubber cup surrounding.When the promotion inflator moves downward, volume of air in the air cavity of piston top is dwindled, pressure increases, making rubber cup be tight against barrel does not allow air drain to below piston, valve open continues downward push piston, when atmospheric pressure is enough to back down the valve inside of tire, pressurized air just enters tire, so just completes the process of once inflating.Such pump efficient is low, inflate discontinuous, and rubber cup gas leakage sometimes, the gas that can not get through is wasted time and energy, and brings inconvenience.
Three, summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of bidirection air intake pump of giving vent to anger is provided, and improves to inflate efficient.
Its technological scheme is: comprise inflator main body, inflator sealing cover, pull bar, piston, inflator main body top is provided with the inflator sealing cover, the inflator body interior is provided with pull bar and piston, it is characterized in that: the bottom of described inflator main body is provided with valve B and valve C, the top of described inflator main body is provided with valve A and valve D, be equipped with spring and steel ball on described valve A, valve B, valve C, valve D, valve B connects steam outlet pipe, is connected by rubber pipe between valve A and steam outlet pipe.
Be provided with seal ring between described pull bar and inflator sealing cover.
The beneficial effects of the utility model are: the bidirection air intake pump of giving vent to anger can shorten the time of inflating greatly, pressure-raising once can be inflated twice, increase and to inflate efficient, can also effectively reduce the height of pump, because pump inside is the leakage that confined space can reduce gas, improves and inflate efficient.
Four, description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of valve in the utility model;
In upper figure: inflator main body 1, spring 2, steel ball 3, inflator sealing cover 4, seal ring 5, pull bar 6, piston 7, rubber pipe 8, steam outlet pipe 9, valve A, valve B, valve C, valve D.
Five, embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
the utility model comprises inflator main body 1, inflator sealing cover 4, pull bar 6, piston 7, the top of inflator main body 1 is provided with inflator sealing cover 4, inflator main body 1 inside is provided with pull bar 6 and piston 7, it is characterized in that: the bottom of described inflator main body 1 is provided with valve B and valve C, the top of described inflator main body 1 is provided with valve A and valve D, described valve A, valve B, valve C, be equipped with spring 2 and steel ball 3 on valve D, valve B connects steam outlet pipe 9, be connected by rubber pipe 8 between valve A and steam outlet pipe 9, be provided with seal ring 5 between described pull bar 6 and inflator sealing cover 4.
During work, the steel ball (3) on valve B and valve D valve B and valve D when piston moves downward open, the epicoele air inlet, and cavity of resorption is given vent to anger; Steel ball (3) on valve A and valve C valve A and valve C when piston moves upward open, and epicoele is given vent to anger, the cavity of resorption air inlet.When portable pull bar moved upward, the pressure of piston upper space increased, the steel ball of air compressing valve A, and spring contraction, gas is discharged, and the steel ball of valve D compresses sealing; Due to the air pressure reason, piston lower space pressure reduces, and valve C opens, and valve B compresses airtight, completes epicoele and gives vent to anger, the cavity of resorption air inlet.When in like manner the hand pull bar moved downward, due to the air pressure reason, outside air backed down valve D, and air enters, and valve A seals because steel ball compresses; Piston lower space volume reduces, and it is large that pressure becomes, and valve B opens, and valve C press seal is completed the epicoele air inlet, and cavity of resorption is given vent to anger.Air outlet use rubber pipe (8) UNICOM of valve A and valve B, when atmospheric pressure was enough to back down the valve inside of tire, pressurized air just entered tire and completes the work of inflating.
Claims (2)
1. bidirection air intake pump of giving vent to anger, comprise inflator main body (1), inflator sealing cover (4), pull bar (6), piston (7), the top of inflator main body (1) is provided with inflator sealing cover (4), the inside of inflator main body (1) is provided with pull bar and piston, it is characterized in that: the bottom of described inflator main body (1) is provided with valve B and valve C, the top of described inflator main body (1) is provided with valve A and valve D, described valve A, valve B, valve C, be equipped with spring (2) and steel ball (3) on valve D, valve B connects steam outlet pipe (9), be connected by rubber pipe (8) between valve A and steam outlet pipe.
2. the bidirection air intake according to claim 1 pump of giving vent to anger, is characterized in that: be provided with seal ring (5) between described pull bar (6) and inflator sealing cover (4).
