Abstract
The leakless pressing structure of hand pump includes a cover, a gland, a hollow column fixed to the gland and with negative hole; a piston shaft inside the hollow column with the upper end inserted into one nozzle and the lower end inserted in a piston and a piston rod; a spring in the lower end of the piston rod and a valve ball in the outlet; a thread part formed with the gland and the nozzle; and an auxiliary valve part on the piston shaft and with a cylinder part and a sliding part. The pressing structure has always closed negative hole unless it is pressed and this can avoid the flow of liquid through the negative hole to the hollow column.
Description
Technical field
The present invention relates to a kind of quantitatively spue fuel priming pump of liquid in container content of combining with container and press laminated structure.
Background technology
Shown in Fig. 1 a and Fig. 1 b, the laminated structure of pressing of existing fuel priming pump comprises the stubborn lid 2 that is combined on the container (not shown), be set in the gland 3 on the lid 2, be fixed in a hollow cylinder h of gland upper end, be formed with a negative pressure hole 4 on the hollow posts body wall, the axis of the piston 7 upsides run through gland 3 and insert in the nozzle 6, a piston p is inserted in its lower end, insert a piston rod 5 again, piston rod 5 further and extend in the hollow cylinder movablely is positioned at the spring S of hollow cylinder inner piston rod lower end, and the hollow cylinder exit is provided with a valve ball 10, gland inwall and nozzle outer wall form can twist the threaded portion 8,8 of closing '.
The existing fuel priming pump of forming by said structure descends by the pressure downforce piston that presses down nozzle, again by the restoring force of spring, liquid in the container is introduced in the hollow cylinder, and spue by nozzle, the outside air that equates with the amount of liquid that is spued is supplemented to bottle by negative pressure hole, thereby keeps container internal pressure.
Yet, when fuel priming pump is not mobile, as shown in Figure 1a, nozzle 6 is by threaded portion 8,8 ' and twist under the state close, perhaps under the state that nozzle breaks away from from the threaded portion shown in Fig. 1 b, if be equipped with that the container of liquid is put upside down or move and be subjected to extraneous extruding, liquid in the container then can enter among the hollow cylinder h by negative pressure hole 4, and spills by the space between lid 2 and the gland 3.This situation occurs in mostly to after pressing of carrying out of the liquid that spues press active interrupt, or has packed under the completion status, therefore can reduce the value and the contaminated environment of product.
Summary of the invention
Above-mentioned defective in view of prior art, the object of the present invention is to provide a kind of laminated structure of pressing of fuel priming pump, though nozzle open or closed condition under, negative pressure hole all is in closed state always, so can stop liquid is introduced hollow cylinder by negative pressure hole phenomenon under any situation even container is reversed or rocks etc.
For achieving the above object, the invention provides a kind of fuel priming pump with drip-preventing function and press laminated structure, the described laminated structure of pressing comprises the lid that is threaded onto on the container, is set in the gland on the described lid, with the fixing stack-mounted hollow cylinder of described gland, be formed with a negative pressure hole on the described hollow cylinder; In described hollow cylinder, the axis of the piston upper end is run through the central part of described lid and described gland and is inserted in the nozzle, and its lower end is with a piston, and described piston is inserted on the piston rod; At described piston-rod lower end one spring is arranged, the described hollow cylinder exit below described spring is provided with a valve ball; In addition, can twist the threaded portion of closing in the outside formation of the inboard and described nozzle of described gland; It is characterized in that a valve assisted parts is set on the described the axis of the piston between described nozzle and described piston; Described valve assisted parts has one and is enclosed within the portion of sliding of sliding on the described the axis of the piston with the drum portion and of described hollow cylinder inwall bearing fit.

Fig. 2 be fuel priming pump of the present invention press the laminated structure cutaway view, wherein fuel priming pump is in closed condition;
Fig. 3 is the cutaway view that is in open mode embodiment illustrated in fig. 2.
The specific embodiment
Fuel priming pump of the present invention press laminated structure be used for container combination to extrude the liquid contents in the container quantitatively.As shown in Figures 2 and 3, this is pressed laminated structure and comprises the lid 2 that is threaded onto on the container 1, is set in the gland 3 on the lid 2, with the fixing stack-mounted hollow cylinder h of gland 3, is formed with a negative pressure hole 4 on the hollow cylinder h.In hollow cylinder, a axis of the piston 7 upper ends are run through the central part of lid 2 and gland 3 and are inserted in the nozzle 6, and its lower end is with a piston p, and piston p is inserted on the piston rod 5.In piston rod 5 lower ends one spring s is arranged, the hollow cylinder exit below spring s is provided with a valve ball 10.In addition, at gland 3 inboard and nozzle 6 outsides formation can twist the threaded portion 8,8 of closing '.
In the present invention, a valve assisted parts 100 is set on the axis of the piston 7 between nozzle 6 and piston p.This valve assisted parts 100 has one and is enclosed within the portion of sliding 120 of sliding on the axis of the piston 7 with the drum portion 110 and of hollow cylinder inwall bearing fit.
As shown in Figure 2, when nozzle 6 and the axis of the piston 7 are in extreme lower position, be that the threaded portion 8 of gland 3 is with the threaded portion 8 of nozzle 6 ' it is fashionable to twist mutually, at this moment, the valve ball is blocked the container contents import of hollow cylinder lower end, content can not enter hollow cylinder, and the outer wall of the drum portion 110 of valve assisted parts 100 is blocked negative pressure hole 4 fully at this moment, introduces hollow cylinder h thereby stopped liquid from negative pressure hole 4.
Again as shown in Figure 3, when nozzle 6 and gland 3 stubborn closes when breaking away from, because the effect of spring s restoring force is risen nozzle 6 fully, piston p makes progress on the valve assisted parts 100 along with the axis of the piston 7 rises and promotes, this moment, the outside wall surface of piston 7 was blocked negative pressure hole 4 fully, stopped content in the container 1 and introduced the phenomenon of hollow cylinders, thereby fundamentally solved the phenomenon of leakage of not pressing under the pressure condition by negative pressure hole 4.
When fuel priming pump is pressed when pressing for the liquid that spues, rise or piston p opens negative pressure hole 4 when descending moment and sucks air with the liquid isodose that spues by valve assisted parts 100, keep suitable pressure in the container 1 with this.
By said structure, when nozzle 6 breaks away from glands 3, when being in complete propradation and need not pressing press operation owing to the restoring force effect of spring s simultaneously, piston p can block negative pressure hole 4 and make container contents impassabitity negative pressure hole 4 hollow cylinder that bleeds; When nozzle 6 passes through threaded portion 8,8 ' and twist when being combined on the gland 3, drum portion 110 outer walls of the valve assisted parts 100 that the present invention is set are blocked negative pressure hole 4 fully, prevent that content is from negative pressure hole 4 hollow cylinder that bleeds, therefore even container is reversed or rocks etc. and can stop content under any state by the negative pressure hole hollow cavity that bleeds, thereby has avoided unnecessary content leaks.
