CN2377971Y - Insulation cup with ventilating valve - Google Patents

Abstract

The utility model relates to a thermos cup. Principally, a through hole is arranged on a cup cover, and a ventilating valve is fixedly arranged in the through hole. The ventilating valve is principally composed of a valve body, a base, a valve core, and a spring. Thus, the thermal insulation degree of the thermos cup is not reduced, and the cup cover can also be easily opened at any state.

Description

Thermos cup with gas valve

The utility model relates to a kind of thermos cup.

At present, the bowl cover of traditional thermos cup is tightened on the cup openend, makes thermos cup sealing and reaches the water insulation that makes in the cup, but, along with the decline gradually of water in the cup temperature, the cup in the water and steam shrinkage and negative pressure appears, cause bowl cover to be difficult for opening, even can't open by suction.

In view of this, the purpose of this utility model provides a kind of thermos cup with gas valve, and it is that an elastic packing valve is set on bowl cover, cause bowl cover to open at need in the water in the cup cooling, as long as the spool top of pushing valve easily makes and enters air in the cup, just can open bowl cover like a cork.

The purpose of this utility model is achieved in that it mainly is made up of cup and bowl cover, offers a through hole on the bowl cover, and set firmly a gas valve in this through hole.This gas valve mainly is made of valve body, base, spool and spring.

Described spool is to have the cylinder of the overhead gage of level near the top, and with top section and rear end section respectively with the small through hole of valve body and the through hole sliding fit on the base.

Owing to adopt such scheme, neither reduce the insulation degree of thermos cup, can also under any state, open bowl cover like a cork.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments schematic diagram;

Among the figure: 1, cup 2, bowl cover 21, through hole 3, gas valve 31, valve body

311, small through hole 32, base 33, spool 331, overhead gage 34, spring

Present embodiment is made up of cup 1 and bowl cover 2, as shown in Figure 1, and wherein:

Cup 1 is general thermos cup, also has heat-insulation layer also can be provided with magnet (making hydromagneticization) outward in it, belongs to prior art.

Bowl cover 2 also is the insulation cover with heat-insulation layer, is screwed on cup 1 openend with it, belongs to prior art, but on bowl cover 2, offer a through hole 21, and set firmly a gas valve 3 in this through hole 21, this gas valve 3 is to be made of valve body 31, base 32, spool 33 and spring 34, wherein:

Valve body 31 is that top central authorities have a small through hole 311, and the bottom is the cylindrical shell of opening, is engaged in admittedly with valve body 31 outer rims in the through hole 21 of bowl cover 2;

Base 32 is to constitute one by boss and base plate that central authorities have a through hole, and in the bottom end opening of valve body 31, and its base plate is against (centre accompanies seal washer) valve body 31 bottom faces with its boss affixed (as: being threaded);

Spool 33 is the cylinders that have the overhead gage 331 of level near the top, these bonding one deck sealants of overhead gage 331 end faces (as: rubber layer) to be keeping the end sealing of overhead gage 331 end faces and valve body 31, and the top section of spool 33 and rear end section respectively with the small through hole 311 of valve body 31 and the through hole sliding fit of base 32;

Spring 34 is nested with between the boss of the overhead gage 331 of spool 33 and base 32, this spring 34 makes the overhead gage 331 tight inboards, top against valve body 31 of spool 33, have only when bowl cover 2 is opened generation difficulty (difficultly), press...with one's finger and press spool 33, air just can enter in the cup 1, and bowl cover 2 is opened and made easily.

Claims (2)

1, a kind of thermos cup with gas valve, mainly form by cup (1) and bowl cover (2), it is characterized in that: offer a through hole (21) on the bowl cover (2), and in this through hole (21), setting firmly a gas valve (3), this gas valve (3) mainly is made of valve body (31), base (32), spool (33) and spring (34).

2, by the described thermos cup of claim 1 with gas valve, it is characterized in that: described spool (33) is to have the cylinder of the overhead gage (331) of level near the top, and with top section and rear end section respectively with the small through hole (311) of valve body (31) and the through hole sliding fit on the base (32).
