Abstract
The utility model relates to a kind of electric hot water tap end cover, comprises housing, inner sealing lid and end cap; Described inner sealing lid is arranged on housing open-mouth, then is tightened on housing by end cap, crush seal inner cap edge, forms the uncovered sealing of housing; It is characterized in that: inner sealing lid central authorities are convexly equipped with a projection towards end cap side, described end cap central authorities correspondence establishes a through hole, there is gap between described projection and through hole.The utility model have be skillfully constructed, structure is simple, the feature of inner sealing lid long service life; One, utilize projection on inner sealing lid to conflict on end cap, form physics spring action; Two, form air spring structure between inner sealing lid and end cap, avoid inner sealing lid open and close along with water tap and produce frequent movement; When temperature turns cold icing, the water body in water tap slowly expands, and its expansive force can crush seal inner cap further, slowly discharges air, to increase the space in housing, reach frost-cracking-preventing object by disappointing groove.
Description
Technical field:
The utility model belongs to instant electric water tap field, particularly a kind of improvement of electric hot water tap sealing end-cover structure.
Background technique:
Existing instant electric water tap, due to quick instant heating and power saving, extensively gets consumer reception.As CN203453610U, disclosed a kind of instant electric water tap, designs comparatively perfect, the especially design of heating chamber, water flow energy is obtained rapidly and uniform heating, meets the need of instant heating.Its structure comprises housing, end cap, valve, handle, electrothermal body, pressure switch and control circuit; Housing disjunctor has cylindricality heating chamber and cylindricality valve pocket, is uncovered structure, is sealed by inner sealing lid and end cap, form complete heating chamber when heating chamber is shaping.There is certain interval between conventional seals inner cap and end cap, inner sealing lid expansion space is provided, during in order to freezing, the effect of protection water tap.Unreasonable owing to designing, cause inner sealing lid when each startup water tap, all produce toward outer lug change, inner sealing lid frequent movement, causes material aging, finally affects life of product, occurs phenomenons such as leaking.
Summary of the invention:
The purpose of this utility model is that a kind of inner sealing lid of design is provided with projection towards end cap side and coordinates the electric hot water tap end cover forming air spring with end cap exhaust hole.
Technical solutions of the utility model are achieved in that a kind of electric hot water tap end cover, comprise housing, inner sealing lid and end cap; Described inner sealing lid is arranged on housing open-mouth, then is tightened on housing by end cap, crush seal inner cap edge, forms the uncovered sealing of housing; It is characterized in that: inner sealing lid central authorities are convexly equipped with a projection towards end cap side, described end cap central authorities correspondence establishes a through hole, there is gap between described projection and through hole.
The projection of described inner sealing lid becomes cone table shape structure, projection end face has the alignment post that a bore is less than described end cap through hole, and projection end face is provided with the above groove that loses heart together, projection end face is conflicted when end cover surface, slowly discharges the air between inner sealing lid and end cap by this disappointing groove.
The utility model have be skillfully constructed, structure is simple, the feature of inner sealing lid long service life; One, utilize projection on inner sealing lid to conflict on end cap, form physics spring action; Two, form air spring structure between inner sealing lid and end cap, avoid inner sealing lid open and close along with water tap and produce frequent movement; When temperature turns cold icing, the water body in water tap slowly expands, and its expansive force can crush seal inner cap further, slowly discharges air, to increase the space in housing, reach frost-cracking-preventing object by disappointing groove.
Accompanying drawing illustrates:
Below in conjunction with concrete legend, the utility model is described further:

Fig. 4 electric hot water tap perspective exploded view
Wherein
Uncovered 2-inner sealing lid, the 21-projection of 1-housing, 11-housing
211-projection end face, 212-alignment post, 213-disappointing groove 3-end cap

Embodiment:
Referring to figs. 1 through Fig. 4, electric hot water tap end cover, comprises housing 1, inner sealing lid 2 and end cap 3; Housing 1 one end is uncovered structure, is called housing uncovered 11, has both been the shaping consideration of housing, also provides passage for installing electrothermal device; Inner sealing lid 2 is arranged on uncovered 11 places of housing, then is tightened on housing 1 by end cap 3, crush seal inner cap 2 edge, forms the sealing configuration at uncovered 11 places of housing; Wherein inner sealing lid 2 central authorities are convexly equipped with a projection 21 towards end cap 3 side, and the central correspondence of end cap 3 establishes a through hole 31, and there is gap between projection 21 and through hole 31.
Furthermore, the formation in this gap, is realized by following structure: described projection 21 one-tenth cone table shape structure, and projection end face 211 has the alignment post 212 that a bore is less than end cap through hole 31, and this alignment post 212 ensures that inner sealing lid is placed in the middle all the time; And projection end face 211 is provided with the above groove 213 that loses heart together, figure Zhong Wei tetra-road; When projection end face 211 is conflicted on end cap 3 surface, the air between inner sealing lid 2 and end cap 3 is slowly discharged by this disappointing groove 213, increase the space in housing 1, to turn cold water body freezing and expansion in housing in order to weather, and usually use keying water tap, the variation in water pressure of formation, be unlikely to affect inner sealing lid 2, produce significantly frequent movement, effectively avoid inner sealing lid 2 aging.Inner sealing lid adopt rubber or latex material shaping.
