Description

Vacuum hand-warming cup

Technical Field

The utility model relates to a drinking cup, concretely relates to hand cup is warmed up in vacuum.

Background

The thermos cup brings convenience and warmth for drinking water for life of people, necessary things for outdoor traveling in winter or in winter are taken away, the thermos cup has already gone into thousands of households, the heat preservation principle is the same as that of a thermos bottle, heat propagation is radiation and transmission usually, cavity gaps between a cup liner and a cup body can delay heat transmission loss, water temperature is kept, although the existing thermos cup can delay heat loss, the function is single, heat cannot be quickly released and cooled to scald a mouth when people need to drink water urgently, and because the cavity blocks heat transmission, the cup body cannot play a heating role, the existing thermos cup with heat conducting liquid in the cavity is provided, the heat conducting liquid is easy to leak in use of a user, and the thermos cup is in production, and because of the existence of the heat conducting liquid in the cavity, the cavity is difficult to be vacuumized, the processing cost is high, and the vacuumizing degree cannot lead to.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a vacuum hand warming cup which can not only delay heat loss and keep water temperature for a long time, but also can quickly release heat and cool when needing to drink water, and can release heat to play a role of warming when in cold days; and in production and processing, the process of vacuumizing the inner cavity is simple, the cost is low, and the vacuum degree of the inner cavity after vacuumizing is high, and the heat preservation effect is good.

In order to achieve the above object, the main technical solution of the present invention is to provide a vacuum hand warming cup, which comprises a cup body, a cup liner arranged in the cup body, a cup bottom arranged at the bottom of the cup body, a cup cover arranged at the top of the cup body, a cup body, an inner cavity formed between the cup bottom and the cup liner, and a powdered or granular heat conducting medium arranged in the inner cavity, wherein the heat conducting medium is gathered to form a heat conducting layer at the bottom of the cup when the cup body is vertically placed, and the maximum thickness of the heat conducting layer is less than the minimum distance from the cup bottom to the cup liner.

The heat transfer medium includes, but is not limited to, metal powder including single metal powder, alloy powder, or refractory compound powder having a metallic property and/or sand.

The heat-conducting medium comprises brass powder.

The heat transfer medium includes iron sand.

The weight ratio of the brass powder to the iron sand in the heat-conducting medium is 1:3-3: 1.

The single metal powder comprises aluminum powder, zinc powder and lead powder; the metal powder in the form of alloy includes copper zinc powder, zinc aluminum powder and stainless steel powder.

Drawings

Figure 1 is a schematic structural diagram of embodiment 1 of the invention,

in the figure: the cup comprises a cup liner 1, a cup body 2, a cup bottom 3, a cup cover 4, an inner cavity 5 and a heat-conducting medium 6.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by simple deformation by a person skilled in the art shall belong to the protection scope of the present invention.

Example 1

As shown in fig. 1, the vacuum hand warming cup described in this embodiment includes a cup body, a cup liner disposed in the cup body, a cup bottom disposed at the bottom of the cup body, a cup cover disposed at the top of the cup body, a cup body, and an inner cavity formed between the cup bottom and the cup liner, wherein a powdered heat conducting medium is disposed in the inner cavity, the heat conducting medium is gathered at the cup bottom to form a heat conducting layer when the cup body is vertically placed, and the maximum thickness of the heat conducting layer is smaller than the minimum distance from the cup bottom to the cup liner. The heat-conducting medium comprises brass powder and iron sand, and the weight ratio of the brass powder to the iron sand is 1: 1. the heat conducting medium can also be single metal powder such as aluminum powder, zinc powder, lead powder and the like, and can also be metal powder in an alloy form such as copper zinc powder, zinc aluminum powder, stainless steel powder and the like. Or the heat conducting medium can be granular as known in the art. The heat transfer medium may also be sand. The heat conducting medium may be granular as known in the art.

When the cup is used, hot water or hot drinks are poured into the cup liner, the cup body is vertically and vertically placed, the heat-conducting medium powder aggregate in the inner cavity is flatly paved at the bottom of the inner cavity to form a heat-conducting layer, the maximum thickness of the heat-conducting layer is smaller than the minimum distance from the cup bottom to the cup liner, the heat of the cup liner cannot be transferred to the cup body through the heat-conducting medium, and hot water in the cup liner can be insulated for a long time; when the urgent need drinks water or need get warm through cup body 2, with the cup body upset, the bottom of cup is vertical placing up, and the powder of heat-conducting medium flows the inner chamber top of cup body and cup courage junction, and the heat of cup courage is through transmitting the cup body through heat-conducting medium, and the hot water is cooled down rapidly in the cup courage can be supplied to drink and not scald the mouth, and cup body temperature rising can be used to warm up the hand. When the water temperature is reduced and water is drunk or the cup body 2 is not needed to be heated, the cup body is turned over, the cup bottom is vertically placed downwards, heat conducting medium powder in the inner cavity flows again and aggregates are flatly paved at the bottom of the inner cavity to form a heat conducting layer, the maximum thickness of the heat conducting layer is smaller than the minimum distance from the cup bottom to the cup liner, the heat of the cup liner cannot be transmitted to the cup body through the heat conducting medium, and hot water in the cup liner can be kept warm for a long time.

During production and processing, the vacuumizing process is multiple, the process is mainly divided into links of air suction, seal welding, cooling and the like, heat-conducting medium powder is added into the inner cavity, the existing vacuumizing process is utilized for direct processing, and compared with vacuumizing of a vacuum cup with an empty inner cavity, the vacuumizing process is not changed and is not influenced. The process of vacuumizing the inner cavity is simple, the cost is low, and the vacuum degree of the inner cavity after vacuumizing is high, and the heat preservation effect is good. And be equipped with the thermos cup of heat conduction liquid in the inner chamber among the prior art, the user leaks easily in using heat conduction liquid, and this type of thermos cup is when producing moreover, because of the existence of heat conduction liquid in the inner chamber, very difficult inner chamber evacuation, and the processing cost is high, and the evacuation degree leads to the heat preservation effect unsatisfactory inadequately.

The brass powder has very small particle size, higher contact area and more efficient heat conduction. However, since the brass powder is separately added into the inner cavity, the flowability is poor, the brass powder is easy to accumulate at a certain position of the inner cavity, and the iron sand or other particles with strong flowability are required to be added and uniformly mixed with the brass powder, so that the mixed powder has high heat conduction efficiency and strong flowability.

Example 2 this example is the same as example 1 except that the weight ratio of brass powder to iron sand is 1: 3.

example 3 this example is the same as example 1 except that the weight ratio of brass powder to iron sand was 3: 1.
