Abstract
The utility model relates to a thermos cup. A cup body is primarily composed of an outer casing, an inner casing, and a vacuum layer 13 between the inner and the outer casings. A valve core is penetrated at the center of a bottom layer of a double-layer cup cover, and two ventilating holes are arranged on the bottom layer and are corresponding to the lower end of the valve core. Thus, the utility model has the advantages of good thermal insulating properties and convenient operation.
Description
The utility model relates to a kind of thermos cup.
At present, common thermos cup is because the thermal conductivity factor of metal shell is very big, very fast heat is delivered on the shell, heat insulation effect is not good, and metal shell is too warm, can scald one's hand when often hand-held, in addition, after thermos cup is poured hot water into, for sealing better, often bowl cover is screwed as far as possible, still, after water temperature descends, the steam shrinkage produces negative pressure in cup, bowl cover is produced suction, make bowl cover be difficult to open, cause trouble.
In view of this, the purpose of this utility model provides a kind of vacuum cup of built-in breather valve, and it is to form vacuum layer between the inside and outside shell of cup, strengthens heat-insulating property, is provided with automatic breather valve again in bowl cover, and bowl cover is opened conveniently.
The purpose of this utility model is achieved in that it mainly comprises cup and bowl cover, it is characterized in that: cup mainly is to be made of the vacuum layer 13 between shell, inner casing and inside and outside shell, bottom center at double-deck bowl cover wears a spool, offer two passages at bottom again, and relative with the spool lower end.
Owing to adopt such scheme: good heat insulating, it is convenient to use again.
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 11, shell 12, inner casing
13, vacuum layer 14, base 2, bowl cover
21, bottom 211, passage 22, spool
23, elastic tape
Present embodiment comprises cup 1 and bowl cover 2, as shown in Figure 1, and wherein:
Cup 1 comprises the vacuum layer 13 between base 14, shell 11, inner casing 12 and the inside and outside shell thereof, and wherein, inner casing 12, shell 11 are all stainless steel, and vacuum layer 13 is cut off the heat conduction of inner casing 12 and shell 11, and heat is lost in the minimizing cup.
Bowl cover 2 is Double layer lids, wears a spool 22 in its bottom 21 in the heart, on this layer 21 two passages 211 is set again, and relative with spool 22 lower ends, bowl cover 2 tops also have the spilehole (not shown) again, in addition, also be provided with elastic tape 23 on the bowl cover 2, make bowl cover 2 keep sealing to contact with cup 1.
Operation principle of the present utility model:
When pouring hot water (boiling water) in the cup 1 into, and screw bowl cover 2, the air pressure of steam is arranged overhead-valve core 22 and is sealed two passages 211, makes the heat of water be difficult for scattering and disappearing; The heat that while cup 1 has vacuum layer 13 partition inner casings 12 is difficult to be transmitted to shell 11, reaches the enhancing heat insulation effect.
Hot water temperature in cup 1 descends, and forms negative pressure in the cup, and spool 22 is inhaled downwards, makes the spilehole (not shown) from the bowl cover 12, in two passages 211 and cup 1, be communicated with, so bowl cover 2 be easy to open, extremely easy to use.
Claims (1)
1, a kind of vacuum cup of built-in breather valve, comprise cup (1) and bowl cover (2), it is characterized in that: cup (1) mainly is to be made of the vacuum layer between shell (11), inner casing (12) and inside and outside shell 13, bottom (21) center at double-deck bowl cover wears a spool (22), offer two passages (211) at bottom (21) again, and relative with spool (22) lower end.
