Abstract
The utility model provides a manually operated inflator, which comprises a valve groupware. The utility model is characterized in that the bottom face of a valve core in the valve groupware is concave facing the body; the concave bottom face of the valve core is an arc concave or a round groove; furthermore, a boss which is integrated on the inner wall of the valve cavity of a piston seat is used for replacing the original valve gasket. Relative to the known manually operated inflator, the utility model increases the contact area through that the bottom face of the valve core is arranged into a concave shape with certain gas storing function; therefore, the up-down movement of the valve core is easier and more energy saving, further ensuring that the puffing action is easier and more energy saving; and the boss which is integrated on the inner wall of the valve cavity of the piston seat is used for replacing the original valve gasket so as to ensure that the accessory is more simple and reduce the production cost.
Description
Technical field
The utility model relates to a kind of inflator pump, refers to a kind of manual inflator pump especially.
Background technique
In the known technology of relevant manually inflator pump, immediate inflator pump structure is disclosed in China Patent No. ZL00201090.9, title: in the patent of multi-functional inflator pump, the advantage of this inflator pump is that health is clean, durable, long service life, and can be various valve tires and balloon inflation.
Yet this patent is also deposited the place of blemish in an otherwise perfect thing when reality is implemented, see also Fig. 1, has shown the agent structure of this multi-functional inflator pump.Be inserted in valve assembly in the urceolus 2 as can be seen from Figure by piston seat 91, the spool of placing in the valve pad 93 that is provided with in the valve chamber in the seal ring 92 that is provided with in piston seat 91 outside annular grooves, the piston seat 91 and the spool chamber of screw fit valve body 94 and screw fit valve body 94 95 constitutes, the inlet hole 912 that setting communicates between the last annular groove of offering the air inlet groove 911 that communicates, piston seat 91 outsides in the middle part of the following annular groove in piston seat 91 outsides and piston seat 91 outsides between sidewall and piston seat 91 upper-end surfaces.Spool 95 wherein is an entity, as shown in Figure 2, its bottom surface is a planar configuration, the inflation principle of inflator pump is can finish gas storage work in the urceolus 2 by handle upwards, and when pressing down, when conduit, inipple and the band of gas that is provided with in the valve assembly that the gas in the urceolus can be provided with by inner core 8 tops, inner core, the base and combination inflator are pressed in tire or the balloon.Be by the moving up and down of the spool in the spool chamber of valve body 94 95 in the overall work process, realize the keying between inner core 8 and the urceolus 2.Therefore whether the action of spool 95 will be to determine to inflate the smooth and easy whether light key of action flexibly.As mentioned above, the spool 95 in the known patent is a flat bottom, and the gas pressure area is limited, thereby slightly dislike effort, really there is undesirable part, in addition the whereabouts that utilizes the other valve pad that is provided with to stop spool 95 in the piston valve base 91 valve chambeies, cause part various, manufacture cost increases.
The utility model content
The utility model is improved in the imperfection part of design at this known manual inflator pump, and purpose is to provide the manual inflator pump of a kind of more light laborsaving and simple element, manufacture cost reduction.
Technical solution adopted in the utility model is for this reason: a kind of manual inflator pump, comprise valve assembly, and it is characterized in that spool bottom surface in the valve assembly to body recess, one-body molded on piston seat valve cavity wall in addition have convex to replace original valve pad.
Said spool bottom surface depression is the cambered surface depression.
Said spool bottom surface depression is round recessed.
Because the utility model is with respect to known manual inflator pump, by the spool bottom surface is set as sagged shape, increased area of contact, and has certain gas storage effect, thereby it is more easily laborsaving to impel spool to move up and down, and makes also that further the inflation action is more easily laborsaving, and has replaced original valve pad with the convex that is shaped in the piston seat internal face, part is more simplified, reduced manufacture cost.
Further describe the utility model below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of known inflator pump.
Fig. 2 is the spool shape schematic representation in the known inflator pump.
Fig. 3 is a manual inflator pump schematic representation of the present utility model.
Fig. 4 is the another kind of example schematic representation of manual inflator pump of the present utility model.
Embodiment
Referring to Fig. 3 and shown in Figure 4, the basic structure of the manual inflator pump of the utility model and known inflator pump are similar, also comprised valve assembly, institute's difference be in the valve assembly spool 95 ' the bottom surface to body recess, formed cambered surface depression 951 (Fig. 3) or be round recessed 952 (Fig. 4), one-body molded on the valve cavity wall in piston seat 91 in addition have convex 93 ' to replace original valve pad 93.
Claims (3)
1, a kind of manual inflator pump comprises valve assembly, it is characterized in that spool bottom surface in the valve assembly to body recess, and one-body molded on piston seat valve cavity wall in addition have convex to replace original valve pad.
2, manual inflator pump according to claim 1 is characterized in that said spool bottom surface depression is the cambered surface depression.
3, manual inflator pump according to claim 1 is characterized in that said spool bottom surface depression is round recessed.
