Abstract

The utility model relates to an improved thermal insulation cup, which relates to a thermal insulation cup with a ceramic housing and a stainless steel liner. The utility model has the purpose that the utility model discloses a technical scheme of the thermal insulation cup with a better thermal insulation effect, and is mainly formed by the method a sealing rubber ring is arranged on a jointing part of an outer flanging of the rim of the cup of a stainless steel inner cover and the edge margin of the rim of the cup of the ceramic housing, a cup cover is provided with a water-drinking switch and a piston ring type sealing ring, a sealing rubber ring is arranged between a bottom cover of the cup and the bottom of the ceramic housing, the bottom of the bottom cover of the cup is provided with two holes and sealing pieces covering the two holes, and the surface of the bottom cover of the cup is fixedly provided with shielding pieces. Because the utility model enhances the improved measures of sealing and thermal insulation on the rim of the cup and the bottom of the cup, not only the structure of the thermal insulation cup tends to reasonableness and perfection, but also the effective thermal insulation effect can be achieved. The utility model is really a beneficial improved cup.

Description

A kind of thermos cup of improvement

Technical field

The utility model relates to thermos cup, refers in particular to a kind of thermos cup with ceramic package and stainless steel inner container.

Background technology

Thermos cup is a daily living article, and it is double-deck that its structure mostly is, and promptly has an inner bag and an overcoat that is mated to constitute.The inner bag of the general stainless steel of many employings is equipped with shell, or stainless steel inner container is equipped with plastic casing etc., and is filled with heat-insulation layer between inner bag and the shell.Existing known a kind of thermal-insulation ceramic cup capable, its built-in stainless steel sleeve, external ceramic case, filling heat-insulation layer between the inside and outside cover, this cup is provided with bowl cover, can drink it but must raise bowl cover when drinking water at every turn, so frequent flip is unfavorable for being incubated.Secondly, the hermetically-sealed construction at the cup end exists not enough and part to be improved.

The utility model content

The purpose of this utility model is intended to disclose a kind of thermos cup of improvement, makes it have better heat insulation effect.The utility model is to adopt following technical scheme to realize: a kind of thermos cup of improvement, comprise cover and therebetween heat-insulation layer, bowl cover, cup bottom sleeve in ceramic package, the stainless steel, it is characterized in that overlapping in the stainless steel in the rim of a cup flanging along being provided with O-ring seal with junction surface, ceramic package rim of a cup edge; Bowl cover is provided with drinking-water switch and piston ring type seal, and the drinking-water switch places the bowl cover end face, and piston ring type seal places the skirt section of bowl cover; The drinking-water switch is made up of drinking-water hole, the cover plate that is shaped on push button and slideway, and the bowl cover end face is made ramped shaped, and the direction along the top, slope to the end, slope is shaped on slideway, and the slideway both sides have the tongue-and-groove of joining with the cover plate cunning, and the sloping base of slideway is provided with the drinking-water through hole; The skirt section of bowl cover is shaped on the groove that is nested with O-ring seal, and the outer surface of O-ring seal is provided with the rib of protrusion; Between cup bottom sleeve and the ceramic package bottom O-ring seal is set; The cup bottom sleeve bottom is provided with the diaphragm seal in 2 holes and this 2 hole of capping; The cup bottom sleeve bottom surface has been installed with cover plate, and cover plate posts heat keeper outward; Bag is equipped with guard ring on the edge that protrude on the bowl cover top.

The thermos cup technical scheme of this improvement because of having strengthened the corrective measure that seals and be incubated at the rim of a cup and the configuration aspects at the cup end, not only makes the structure of thermos cup be tending towards reasonable and perfect, and has obtained more efficiently heat insulation effect.The utility model is a kind of useful improvement in fact.

Description of drawings

Fig. 1 shows the decomposition texture schematic diagram of a kind of embodiment of the utility model;

Fig. 2 is the broken section structural representation of bowl cover and end face thereof.

The specific embodiment

Be described further with regard to this embodiment in conjunction with the accompanying drawings.Present embodiment is made up of bowl cover 1, cup 2 and base sheath 3 etc., interior cover 23, heat-insulation layer 22 and ceramic package 21 as a kind of stainless steel constitute cup 2, cover 23 rim of a cup flangings are interior along being equipped with O-ring seal 20 with ceramic package 21 rim of a cup edge abutting ends in the stainless steel, its objective is except that insulation, strengthened the sealing function when between interior cover 23 and shell 21, filling insulation material 22, also reached and guarantee that the insulation material that fills does not leak.Between cup bottom sleeve 3 and ceramic package 21 bottoms O-ring seal 31 is set, the bottom of cup bottom sleeve 3 is provided with the diaphragm seal 32 in 2 holes 30 and this 2 hole of capping, the effect of this structure is, when interior cover 23 is inserted therebetween with shell 21 assemblings and with O-ring seal 20, the cup bottom is inserted O-ring seal 31 earlier and is detained the bottom screw that cup bottom sleeve 3 usefulness tapping screws 4 are screwed into interior cover 23 again, ceramic package 22 tightly is sandwiched in therebetween, then, 30 filled polyurethane foamed plastics are made heat-insulation layer 22 through the hole, after finishing, injection moulding seals with diaphragm seal 32, the back welds with stainless steel cover plate 5 and base sheath, the improvement of this structure mainly is that outer the blending that prevents insulation material avoids cup to prevent that when cleaning the bottom water inlet from losing heat insulation effect, and the globality of having reinforced cup.Stainless steel substrates 5 is pasted slipmat 6 again, to increase the stability of cup.Be the purpose that realizes that not flip can be drunk water, the utility model is provided with drinking-water switch and piston ring type seal on bowl cover 1, the drinking-water switch is made up of drinking-water hole 13, cover plate 12 and slideway 14, bowl cover 1 end face is made slope 15 shapes, direction along slope top to the end, slope is shaped on slideway 14, the slideway both sides have with cover plate 12 sliding tongue-and-grooves of joining (this groove be known dovetail or general groove all can, diagrammatic sketch is slightly), the sloping base of slideway 14 is provided with drinking-water through hole 13, and the cover plate face is shaped on push button 121; When need are drunk water, make this plate 12 to the slip of tiltedly putting on hand propelled push button 121, expose drinking-water hole 13 and can drink it.Be convenient drinking-water, domatic 15 sloping top relies on one side of caping convex edge, and the gap of the end, slope with the edge that caping protrudes then is connected do transition with the curved surface of slyness.So-called piston ring type seal is to be shaped on the groove 10 that is nested with O-ring seal 101 in the skirt section of bowl cover 1, the outer surface of O-ring seal 101 is provided with two ribs 1011 of protrusion, when bowl cover covers into cup, having certain flexible O-ring seal 101 and rib 1011 thereof pushed by the cup inwall, elastic force and frictional force because of cushion rubber makes bowl cover be difficult for deviating from the one hand, and also the rib because of two protrusions has the sealing effectiveness that airtight effect has obtained " dual fail-safe " as piston ring.So the bowl cover of this structure not only heat insulation effect is good, and can keep watertight when the inclination cup is drunk water, even or this thermos cup placed in the automobile that travels, also can keep the water in the cup can not shake out.For making the thermos cup outward appearance hold the uniformity and the harmony of overall aesthetic, bag is equipped with the guard ring 11 of stainless steel on the edge of the top of bowl cover 1 protrusion.
