Abstract
The utility model discloses a pump bowl, concretely relates to manual formula pump bowl that bulldozes, including cylinder, cylinder head, piston piece, sealing washer, piston rod, handle, the cylinder bottom is equipped with one -way discharge valve, be equipped with one -way admission valve in the cylinder head, the sealing washer with the piston block group together to has the one -way ventilation function. The utility model discloses during the use, if the rebound of piston piece, the one -way ventilation orifice flow of the gaseous accessible piston piece of piston piece upper portion air chamber is to piston piece lower part air chamber, if the piston piece moves down, the one -way discharge valve of gaseous accessible in the air chamber of piston piece lower part discharges, and the gas in the air chamber of piston piece upper portion will obtain supplying through one -way admission valve simultaneously. The piston piece reciprocates during the operation, bleeds to take place in the piston piece process of moving down hard. Combine human application of force characteristics for it is more laborsaving to bleed.
Description
Technical field
This utility model relates to a kind of pump bowl, particularly relates to a kind of manual push-press type pump bowl.
Background technology
Pump bowl and its operation principle contrast of inflator commonly used now.Inflator is that pushing piston discharges gas, and pump bowl is that lifting piston is pumped into gas, and simply intake and exhaust valve is inverted mutually setting.Under prior art, hand-held pump bowl has multiple, mostly is the pump bowl of hand-held pull-type, incompatible with human body force feature during use, bleeds laborious.
Summary of the invention
This utility model mainly overcomes above technical deficiency, it is provided that a kind of manual push-press type pump bowl.
The pump bowl of handheld pull-type changes hand-held push-press type pump bowl into.
Make piston block move up and down during operation, will bleed and firmly occur to move down process at piston block, adapt with human body force feature, bleed laborsaving.
This utility model is achieved through the following technical solutions: a kind of manual push-press type pump bowl, including cylinder, cylinder head, piston block, sealing ring, piston rod, handle.
Described cylinder bottom is provided with one-way exhaust valve, for aerofluxus, prevents air inlet.
Described cylinder head is provided with breather cheek valve, for air inlet, prevents aerofluxus.
Described cylinder forms closed cavity together with described cylinder head.
Closed cavity is divided into upper and lower two parts air chamber together with described sealing ring by described piston block, and sealing ring and piston block are combined and had one-way ventilating function so that gas can only from up to down pass through piston block.
Described piston rod is used for connecting described piston block and described handle, and piston rod passes cylinder head central through hole, and tight with through hole laminating, has good air-tightness.
When this utility model uses, drawing handle, if piston block moves up, the one-way exhaust valve of cylinder bottom is closed, and piston block top air chamber gas can flow to piston block bottom air chamber by the one-way ventilating hole of piston block.
If piston block moves down, the one-way exhaust valve of cylinder bottom is opened, and the gas in the air chamber of piston block bottom is discharged by one-way exhaust valve, and the breather cheek valve in cylinder head is opened simultaneously, gas in the air chamber of piston block top will be supplemented by breather cheek valve, thus play air-extraction function.
This utility model compared to existing technology, has the beneficial effect that: the one manual push-press type pump bowl that this utility model provides, during operation, drawing handle makes piston block move up and down, and bleeds and firmly occurs to move down process at piston block.
The one manual push-press type pump bowl that this utility model provides, pushes pumping process and adapts with human body force feature so that bleed more laborsaving.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a kind of manual push-press type pump bowl of this utility model.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment is implemented under premised on technical solutions of the utility model, gives detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Seeing Fig. 1, a kind of manual push-press type pump bowl, including cylinder 1, cylinder head 2, piston block 3, sealing ring 4, piston rod 5, handle 6.
Cylinder 1 and cylinder head 2 are by screw socket 12 and swivel nut 23 fixing composition closed cavity.
Sealing ring 4 is between piston block 3 and cylinder 1 inwall so that keep good air-tightness between piston block 3 and cylinder 1 inwall, and piston block 3 makes piston block 3 have one-way ventilating function together with sealing ring 4.
Piston block 3 is connected by piston rod 5 with handle 6, and piston rod 5 is through the through hole 21 at cylinder head 2 center.
Working method: when piston block moves up, the one-way exhaust valve closedown of cylinder bottom, piston block top air chamber gas can flow to piston block bottom air chamber by the one-way ventilating hole of piston block.
When piston block moves down, the one-way exhaust valve of cylinder bottom is opened, and the gas in the air chamber of piston block bottom is discharged by one-way exhaust valve, and the breather cheek valve in cylinder head is opened simultaneously, gas in the air chamber of piston block top will be supplemented by breather cheek valve, thus play air-extraction function.
Above content is only to this utility model example and explanation; described specific embodiment is made various amendment or supplements or use similar mode to substitute by affiliated those skilled in the art; without departing from utility model or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
