Abstract
The utility model discloses a vacuum cup cover which is connected to a vacuum cup in a screw joint mode or in a clamping mode. The vacuum cup cover comprises an outer layer and an inner layer. An inner cavity is arranged between the outer layer and the inner layer. A vacuum is arranged inside the inner cavity. Meanwhile, an aspirating hole is further formed in the vacuum cup cover and provided with a sealing block. After the vacuum cup cover is optimized, a concave pit is arranged on the upper end face of the outer layer. The aspirating hole is located inside the concave pit. The outer layer and the inner layer are prepared by stainless steel. The vacuum cup cover has the advantages that heat preservation effect is quite good, the heat preservation effect of the vacuum cup can be guaranteed all-dimensionally. Further, when the vacuum cup cover is used as a container, the hands of a user cannot be scalded.
Description
Technical field
The present invention relates to the household articles technical field, especially relate to a kind of heat-insulating cup cover.
Background technology
At present, the thermos cup of the materials such as the stainless steel preparation of the inner vacuum pumping of wall of cup widely uses.Because its heat insulation effect is better, thereby extremely welcome.But, this thermos cup oral area be spirally connected or the most heat insulation effect of bowl cover of clamping relatively poor, thereby heat runs off in a large number from bowl cover, and then has greatly weakened the heat insulation effect of this thermos cup.Simultaneously, when utilizing this bowl cover to hold hot water as containers such as bowls, because its heat conductivity is better, thus comparatively hot, use inconvenience.Therefore be necessary to be improved.
Summary of the invention
Deficiency for above-mentioned prior art exists the purpose of this invention is to provide a kind of heat-insulating cup cover, and it is better that it has heat insulation effect, heat insulation effect that can comprehensive assurance thermos cup, and it is when using as container, the characteristics that can not scald one's hand.
To achieve these goals, the technical solution adopted in the present invention is: heat-insulating cup cover, it is spirally connected or is connected on the thermos cup, described heat-insulating cup cover comprises skin and internal layer, and being provided with inner chamber between skin and the internal layer, is vacuum in the inner chamber, simultaneously, heat-insulating cup cover also is provided with aspirating hole, and this aspirating hole is provided with sealing block.
Described outer field upper surface is provided with pit, and aspirating hole is positioned at this pit.
The diameter D of described aspirating hole is: 0.5mm≤D≤3mm.
The diameter D of described aspirating hole is: D=1mm.
Described skin and internal layer are skin and the internal layer of stainless steel preparation.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: heat insulation effect is better, heat insulation effect that can comprehensive assurance thermos cup, and it can not scald one's hand when using as container.Heat-insulating cup cover of the present invention is double-decker, and vacuum pumping in the inner chamber.Like this, this heat-insulating cup cover is the same with thermos cup has a fabulous heat insulation effect.That is, the material in the thermos cup has obtained omnibearing insulation.Simultaneously, the vacuum of heat-insulating cup cover inside can intercept the rapid transmission of heat, thereby when it holds hot water as container, can not scald one's hand.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks cutaway view;
Fig. 2 is the A section enlarged drawing of Fig. 1.
The specific embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: heat-insulating cup cover, it is spirally connected or is connected on the thermos cup 30.This heat-insulating cup cover comprises skin 11 and internal layer 12, and is provided with inner chamber 13 between skin 11 and the internal layer 12.Wherein, skin 11 and internal layer 12 can weld together.Certainly, the heat-insulating cup cover of this moment is used for and thermos cup 30 is spirally connected or screw thread or the draw-in groove of clamping are positioned at internal layer 12.Simultaneously, in the inner chamber 13 be vacuum.In order to vacuumize for inner chamber 13, heat-insulating cup cover also is provided with aspirating hole 112.When vacuumize finish after, this aspirating hole 112 is provided with sealing block 20.Sealing piece 20 can be pricker envelope piece.Like this, the vacuum in this heat-insulating cup cover has improved the heat insulation effect of this heat-insulating cup cover, has prevented that the too fast of thermos cup internal heat from distributing, and heat-insulating cup cover can not scald one's hand when using as container.
Optimize, outer 11 upper surface is provided with pit 111, and aspirating hole 112 is positioned at this pit 111.Like this, not only be convenient to inner chamber 13 is carried out vacuum pumping, and vacuumize and finish and with after aspirating hole 112 sealing, can in the pit 111 interior cosmetic sheet that arrange, avoid the exposed of aspirating hole 112.
Further, the diameter D of this aspirating hole 112 is: 0.5mm≤D≤3mm.Optimum, the diameter D of aspirating hole 112 is: D=1mm.The size of such aspirating hole 112 is beneficial to vacuum pumping and sealing.
For good looking appearance, skin 11 and internal layer 12 can be taked the stainless steel preparation.
