Abstract
The utility model relates to an automatic temperature-control vacuum cup. An intercalated bed is provided between the inner wall and the outer wall of the cup. The intercalated bed is not vacuumed. An opening is provided at the bottom part of the intercalated bed. An one-way air pressure valve is provided in the opening. The one-way air pressure valve is able to be opened and closed with the increasing and decreasing of the barometric pressure of the intercalated bed. The air pressure valve comprises a draught spring and an air pressure valve cap. When pouring boiling water into the vacuum cup, the air pressure of the intercalated bed is increased and decreased through the temperature rising and falling. Therefore, the air is exhausted outward and the intercalated bed forms a thin air and approximately vacuum condition. The heat preservation effect of the cup is realized. The utility model has the advantages of simple production technique, no need of vacuum pumping, and no worry about air leakage and no heat preservation. Meanwhile, the prior period cooling speed of the cup is higher than the common vacuum cup. The suitable drinking temperature is more quickly achieved.
Description
Affiliated technical field
The utility model is about new type auto thermos cup.
Background technology
Thermos cup on the market all is to utilize the vacuum between cup outer wall and the cup inwall to be incubated now, and its advantage is exactly that temperature retention time is long.Though heat insulation effect is good, owing to reasons such as craft method are single, so along with the increase of its service time and increasing of access times, the heat insulation effect of this common thermos cup can be worse and worse; And people will wait for for a long time just reaching suitable consumption temperature when using conventional thermos cup to drink water.
Summary of the invention
The utility model purpose is to utilize new design that a kind of processing simple in structure, easy, automatic heat preserving are provided, and is more suitable for people's novel heat insulation cup used in everyday.
The automatic temperature-controlled thermos cup of the utility model is to stay an interlayer between the inner and outer wall of cup, but does not vacuumize, but stays a duck eye in the bottom of interlayer, adorns an air pressure valve that can strengthen and weaken and open and close with air pressure in the hole.Like this when we pour hot water into this glass, temperature raises, and pressure increases and backs down air pressure valve the air in the interlayer because temperature increases, and air is discharged; Along with the discharge of air in the interlayer, when pressure equals the outer atmospheric pressure of cup, air pressure valve will be rejected and close.Interlayer between the inside and outside wall of cup will form the interface interlayer of a rarefaction of air, near vacuum like this, has reached certain heat insulation effect.
The automatic temperature-controlled thermos cup of the utility model is compared with existing thermos cup, production technology is simple, need not to vacuumize, because of being utilizes the hot water and the outer temperature difference of cup to extract the interior air of cup interlayer automatically out, so needn't worry cup gas leakage is not incubated, whenever pour boiling water into one time, exactly a process of bleeding automatically.Simultaneously cup early stage cooling velocity faster than common thermos cup, can reach suitable consumption temperature quickly.

The specific embodiment
As Fig. 1,2,3,4, the utility model has inside and outside two-layer wall of cup 1,2 and intermediate course 3, at the hypomere of outer wall 1 opening 9 is arranged, and tension springs 5 link to each other with air pressure valve gap 7 in the opening 9, the upper end of tension spring 5 links to each other with the bottom of inwall 2, and the cup upper end is a bowl cover 6.When pouring hot water into glass chamber 4, inwall 2 temperature raise, air themperatures in the interlayer 3 also increase expansion, cause air pressure to increase, air pressure greater than cup outside during atmospheric pressure, in interlayer 3 under the air effect, air pressure valve gap 7 is backed down as shown in Figure 2, and air are discharged rapidly outside the cup through opening 9 in the interlayer 3, until interlayer 3 inner air pressures and cup outer air pressure near the time, as Fig. 3, air pressure valve gap 7 is closed under the effect of tension spring 5.Along with 8 decrease of temperature of hot water in the cup, the volume of air in the interlayer 3 is constantly shunk, density descends, and the outer air of cup just forms a rarefaction of air in the interlayer 3, is similar to the state of vacuum because the obstruct of air pressure valve gap 7 is difficult to enter interlayer 3 again this moment.Cup has just had heat insulation effect preferably like this.
