The vacuum heat preservation cup lid can keep the water temperature inside the cup body for a longer time.

Description

The vacuum heat-preserving bowl cover

Technical field

The utility model relates to a kind of bowl cover with good disconnected hot merit energy.

Background technology

The thermos cup that hollow heat insulation cup namely is generally called due to the function that has thermal-insulating and excessively scald when avoiding hand to take, thereby is commonly that people use and welcome.Existing hollow heat insulation cup structure, make double-decker mainly with stainless steel material greatly, it includes an outer wall and an inwall, is disconnected heat space between outer wall and inwall, disconnected heat space namely gives during fabrication and vacuumizing, and avoids air as the heat-conducting medium between outer wall and inwall.Because traditional hollow heat insulation cup has good effect of heat insulation, even the in-built boiling hot hot water of cup can not feel hot when user's hand grips outer wall yet.

Although the cup of existing hollow thermal-insulating cup has good heat insulation effect; yet; the existing bowl cover that is used for coordinating this cup is but without any structural design that can the trap heat conduction; therefore; water temperature or the heat of splendid attire in cup distributed by bowl cover after often can conducting to bowl cover, thereby reduced thermos cup and in fact can keep for a long time the effect of water temperature.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the defects that prior art exists, and a kind of vacuum heat-preserving bowl cover is provided, and it can allow thermos cup keep heat insulation effect for more time.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of vacuum heat-preserving bowl cover, that sidewall in an end face of a bowl cover and ring week is formed with a lateral wall and a madial wall one-body moldedly, form the disconnected heat space of a vacuum between this lateral wall and madial wall, and the internal diameter of this madial wall is formed with internal thread, by this internal thread spiral be combined in one have equally disconnected hot merit can cup external screw thread and consist of a thermos cup, be able to the longer time and keep water temperature in cup.

The utility model is that the bowl cover at the cup that is used for being matched with vacuum cup further is formed with the disconnected heat structure of vacuum, consist of a more perfect disconnected thermotectonics after making the combination of cup and bowl cover, the heat of the water of splendid attire in cup can't directly be conducted via cup and bowl cover, thereby can more delay distributing of the interior heat of cup, reach the heat insulation effect of longer time.

The beneficial effects of the utility model are that it can allow thermos cup keep heat insulation effect for more time.

Description of drawings

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

Fig. 1 is the embodiment section plan of the utility model vacuum heat-preserving bowl cover structural form.

Fig. 2 is the bowl cover of the utility model vacuum heat-preserving bowl cover and the three-dimensional exploded view of cup syntagmatic.

Fig. 3 is the embodiment section plan of the structure after the utility model vacuum heat-preserving bowl cover and cup combination.

The number in the figure explanation:

1 bowl cover

11 lateral walls

12 madial walls

13 disconnected heat spaces

14 internal threads

2 cups

21 external screw threads

22 lateral walls

23 madial walls

24 disconnected heat spaces

The specific embodiment

Consult Fig. 1, the vacuum heat-preserving bowl cover that the utility model provides, its preferred embodiment is to be formed with a lateral wall 11 and a madial wall 12 at an end face of a bowl cover 1 and the sidewall in ring week one-body moldedly, form a disconnected heat space 13 between this lateral wall 11 and madial wall 12, and the internal diameter of this madial wall 12 is formed with internal thread 14; Described disconnected heat space 13 is confined spaces, and it is fully deflated when making this bowl cover 1 and forms vacuum, makes the medium that there is no to conduct heat between lateral wall 11 and madial wall 12.

Fig. 2 and Fig. 3 show bowl cover 1 of the present utility model and have equally the combining structure of the cup 2 of heat insulation effect; Described cup 2 is used for the container of the liquid such as splendid attire water, tea or beverage, and it has the interior space of past downward-extension one degree of depth, a upper square opening in interior space, the external diameter of opening be provided with can with the external screw thread 21 of aforesaid internal thread 14 spirals cooperations; Cup 2 has lateral wall 22 and madial wall 23, consists of a disconnected heat space 24 between this lateral wall 22 and madial wall 23; Further it, the lateral wall 22 of cup 2 and madial wall 23 are by the one moulding manufacturing of extending, keep a distance to form disconnected heat space 24 between lateral wall 22 and madial wall 23, the heat space 24 interior air that then will break are extracted the formation vacuum fully out, the vacuum state that there is no air dielectric in the disconnected heat space 24 is avoided the fluid temperature in the interior space of cup 2 to scatter and disappear.

By the structure of aforesaid bowl cover 1 with lid 2, after the liquid such as the interior splendid attire water of cup 2, tea or beverage, directly the internal thread 14 of bowl cover 1 is screwed together in the external screw thread 21 of cup 2, can avoids the interior heat of cup 2 from cup 2 and bowl cover 1 heat loss through conduction, thereby reach the effect of long-time insulation.

The above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.

Claims (1)

1. a vacuum heat-preserving bowl cover, is characterized in that, the sidewall all at an end face and the ring of a bowl cover is formed with a lateral wall and a madial wall one-body moldedly, forms the disconnected heat space of a vacuum between this lateral wall and madial wall.
