Abstract
The utility model discloses a novel stainless steel vacuum cup cap structure which is characterized by comprising a cup cap body (1). An air discharging valve (2) is arranged on the cup cap body (1) and placed in an air-bleed hole (3) and the air-bleed hole (3) is designed to be a through hole. The air discharging valve is arranged on the cup cap body and is in a closed state when the novel stainless steel vacuum cup cap structure is used at ordinary time. When water in a stainless steel vacuum cup is cooled and the cup cap body can not be opened due to generated differential pressure, the air discharging valve can be opened so that the differential pressure can be eliminated, the cup cap body can be opened easily and normal use can be recovered. After the differential pressure is eliminated, the fingers are released and the air discharging valve can be automatically returned to the closed state. The novel stainless steel vacuum cup cap structure is simple in structure design, high in practicality, easy to machine and good in economic benefit.
Description
Technical field
The utility model relates to a kind of novel stainless steel thermos cup cup lid structure, belongs to the heat-preserving equipment technical field.
Background technology
The high-grade stainless steel thermos cup of producing before several years, its good seal performance (light supination is put upside down and can not seeped water out), high insulating effect, pass through repetition test, exist a major defect, namely contain upward and do not use in 4-5 hour at interval behind the hot water, then the situation that bowl cover is not opened can occur after the water cooling, this is that inner air cooling back gas pressure reduces, and makes due to the inside and outside formation of the cup pressure reduction.Though availablely for a long time external heat or specific purpose tool are opened, are brought very big inconvenience to the user.To present production 20 surplus the stainless steel thermos cup of a kind examine or check, discovery bowl cover internal layer is used plastics instead, basically solved the problem of not opening after the cooling, but new problem has occurred: use sealing and heat insulating ability all to have a greatly reduced quality, by test, put upside down after screwing on bowl cover, water can ooze out, and the things such as mobile phone in the bag are got wet.
Summary of the invention
The purpose of this utility model: be to provide a kind of novel stainless steel thermos cup cup lid structure, solve high-grade thermos cup in use, form pressure reduction easily, the problem that is difficult to open.
The technical solution of the utility model: a kind of novel stainless steel thermos cup cup lid structure, include the bowl cover body, bowl cover is provided with a vent valve, and vent valve is placed in the air vent, and air vent is via design.
Above-mentioned novel stainless steel thermos cup cup lid structure, described vent valve is small ball valve, conical valve or flat head screw.
Above-mentioned novel stainless steel thermos cup cup lid structure, described air vent is deep hole or screwed hole.
The beneficial effects of the utility model a: vent valve is set at bowl cover, this valve is in closed condition in using at ordinary times, when pressure reduction occurring after the water cooling in the cup and not opening, open vent valve to eliminate pressure reduction, can easily open bowl cover, recover normal and use, pressure reduction unclamps finger after eliminating, and vent valve automatically reverts to closed condition.This structural design is simple, but the practicality height is easy to processing, has good economic benefit.
Description of drawings
Accompanying drawing 1 is small ball valve arrangement schematic diagram of the present utility model;
Accompanying drawing 2 is conical valve structural representation of the present utility model;
The 1-bowl cover, 2-vent valve, 3-air vent.
The specific embodiment
Embodiment 1 of the present utility model: novel stainless steel thermos cup cup lid structure, include bowl cover 1 body, bowl cover 1 is provided with a vent valve 2, and vent valve 2 is placed in the air vent 3, should be via design in air vent 3 manufacturing process.
Embodiment 1 of the present utility model: as shown in Figure 1, this vent valve 2 is small ball (pearl) valve, be similar to a kind of pearl that bumps, vent valve 2 is installed in the bowl cover 1, valve body top concordant with bowl cover 1 end face (being interference fit between them), as shown in Figure 1, vent valve 2 is connected with spring, initial tension of spring makes steel ball often place the top to be in closed condition, when the water cooling in the long period thermos cup pressure reduction occurs and does not open, only need gently depress steel ball opens valve, because air vent 3 is via design, makes the realization that is interlinked to the outside in the cup eliminate pressure reduction by valve body underneath pore 3.Pressure reduction is eliminated the back and is decontroled hand, and steel ball rebounds automatically vent valve 2 cuts out in the valve.
Embodiment 2: as shown in Figure 2, vent valve 2 is conical valve, and valve body is similar to case one, and difference is that vent valve is not steel ball, but valve body top is cone, and the bottom is cylindrical conical valve, and taper seat is realized sealing under the initial tension of spring effect.Conical surface top is exposed to the bowl cover top in the time of in off position, and central authorities can exceed a glass end face 2-3mm.When the long period pressure reduction do not occur and do not open with water cooling, only need gently depress the roundlet conehead opened valve, made to be interlinked to the outside in the cup by valve body underneath pore 3 and realized eliminating pressure reduction.
Embodiment 3: as shown in Figure 3, the air vent 3 that the bowl cover top is offered is screwed hole, and vent valve 2 is a flat head screw, about diameter 2mm, can place a rubber washer below, screw a little and make vent valve 2 be in closed condition, the screw end face is concordant with the bowl cover end face when closing, and does not affect the appearance; When the long period pressure reduction do not occur and do not open with water cooling, only need can easily realize just that with key chain or mother's nail rotary screw venting eliminates pressure reduction that screw gently again after opening, vent valve 2 cuts out.
