Abstract
The utility model provides a pair of vacuum cup cover, including the bowl cover body, the bowl cover body is provided with opening direction and bowl cover body opening direction and annular groove, corresponding to the annular groove is provided with the elasticity sealing washer, the lower surface of elasticity sealing washer sinks to forming fits shape complex seal groove with the thermos cup rim of a cup, the elasticity sealing washer passes through the bottom fixed connection of spring and annular groove, can make forms effective sealing up between vacuum cup cover and the cup to prevent the inside and outside air convection of cup, effectively improve the heat preservation effect, but also can effectively prevent the liquid outflow in the cup.
Description
Technical field
The utility model relates to a kind of articles for daily use, particularly relates to a kind of vacuum cup cover.
Background technology
Thermos cup is article conventional in daily life, be mainly used in hot water, existing thermos cup is made up of cup and bowl cover, current cup generally adopts double walled cup, and vacuumizes between the double side wall of cup, thus reaches good heat insulation effect, but, still just there is gap in bowl cover and cup, causes between cup and bowl cover poorly sealed, thus affect heat insulation effect.
Therefore, need to propose a kind of new vacuum cup cover, can make between vacuum cup cover and cup, to form effective sealing, thus prevent the cross-ventilation inside and outside cup, effectively improve heat insulation effect, but also effectively can prevent the liquid outflow in cup.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of vacuum cup cover, can make to form effective sealing between vacuum cup cover and cup, thus prevents the cross-ventilation inside and outside cup, effective raising heat insulation effect, but also effectively can prevent the liquid outflow in cup.
A kind of vacuum cup cover that the utility model provides, comprise bowl cover body, described bowl cover body is provided with opening direction and bowl cover body openings direction and annular groove, described annular groove is provided with elastic seal ring, the lower surface of described elastic seal ring sinks to being formed the seal groove with thermos cup rim of a cup form-fit, and described elastic seal ring is fixedly connected with the bottom of annular groove by spring.
Further, the two side opening part of described annular groove is cancave cambered surface structure, the upper surface of described elastic sealing gasket and cancave cambered surface structure form-fit.
Further, described elastic sealing gasket is provided with the edge of a wing.
Further, the middle part of described bowl cover body bottom portion convexes to form formation spherical surface hill downwards, and this spherical surface hill inside is hollow structure.
The beneficial effects of the utility model: vacuum cup cover of the present utility model, can make between vacuum cup cover and cup, to form effective sealing, thus prevent the cross-ventilation inside and outside cup, effectively improve heat insulation effect, but also effectively can prevent the liquid outflow in cup.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation after elastic seal ring of the present utility model release.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, Fig. 2 is the structural representation after elastic seal ring of the present utility model release, as shown in the figure, a kind of vacuum cup cover that the utility model provides, comprise bowl cover body 1, described bowl cover body 1 is provided with opening direction and bowl cover body 1 opening direction and annular groove 2, described annular groove 2 is provided with elastic seal ring 6, the lower surface of described elastic seal ring 6 sinks to being formed the seal groove 7 with thermos cup rim of a cup form-fit, described elastic seal ring 6 is fixedly connected with by the bottom of spring 3 with annular groove 2, as shown in Figure 1, when deployed, the rim of a cup of cup can conformally be embedded in seal groove, be threaded connection between vacuum cup cover and cup, after screwing bowl cover, the rim of a cup of thermos cup is by Compress Spring, so spring also just applies pretightning force to cup, thus can make between vacuum cup cover and cup, to form effective sealing, thus prevent the cross-ventilation inside and outside cup, effective raising heat insulation effect, and when carrying thermos cup and going out, effectively can also prevent the liquid outflow in cup, easy to use.
In the present embodiment, the two side opening part of described annular groove 2 is cancave cambered surface structure 8, the upper surface of described elastic sealing gasket 6 and cancave cambered surface structure 8 form-fit, by this structure, the sidewall of elastic sealing gasket and annular groove has larger bonded area, thus effectively improve sealing effectiveness, in order to make the more stable of structure, further lift-off seal effect, described elastic sealing gasket 6 is provided with the edge of a wing 4, fit tightly with the lower surface of the sidewall of annular groove after this edge of a wing 4 screws between bowl cover and cup, improve sealing effectiveness further, wherein, elastic sealing gasket adopts existing elastomeric material.
Middle part bottom the body of bowl cover described in the present embodiment 1 convexes to form downwards and forms spherical surface hill 5, when thermos cup is built with hot water, steam condenses on spherical surface hill, after steam condensation, pass through said structure, the globule of condensation is easy to be back in thermos cup, thus can not be local at other by water droplet when opening bowl cover, especially in working environment, the globule is effectively prevented to be dropped on file, this spherical surface hill 5 inside is hollow structure, adopts this structure, effectively can strengthen heat insulation effect.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
