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.
As shown in fig. 1-3, the efficient heat-preservation hand-warming cup described in this embodiment includes a cup body, a cup mouth, and a cup cover, and is characterized in that the cup cover includes an outer cover and a cover liner provided in the outer cover, the outer cover is connected with the cover liner, a closed cavity is formed between the outer cover and the cover liner, and a heat-conducting medium is provided in the cavity.
The cup opening is in threaded connection with the cup cover, and the connection mode of the cup opening and the cup cover can also be other existing clamping modes and the like. The cup body is of a double-layer structure with a vacuum inner cavity. The cup cover is also a double-layer structure with a cavity close to vacuum, so that the water temperature in the cup can be kept for a long time.
The heat-conducting medium is gathered at the bottom of the cavity when the cup body and the cup cover are placed upright, the surface height of the heat-conducting medium is lower than the height of the top of the cover liner, the cup body is of a double-layer vacuum structure, and the cup cover is of a structure close to the vacuum double-layer structure, so that the temperature of liquid in the cup can be kept for a long time;
the heat-conducting medium is gathered at the top of the cavity when the cup body and the cup cover are placed in an inverted or inclined mode, and the maximum height of the surface of the heat-conducting medium is equal to or higher than the minimum height of the top of the cover liner.
The heat-conducting medium is heat-conducting liquid, the boiling point of the heat-conducting liquid is 30-100 degrees, and when the cup body and the cup cover are inverted or inclined, the heat-conducting medium can simultaneously contact the top of the cover liner and the top of the outer cover. When the cup is used, the cup cover is opened, hot water is poured into the cup body, the cup cover is screwed, and when the cup is vertically and forwardly placed, heat-conducting liquid or heat-conducting powder in the cavity of the cup cover is not contacted with high-temperature liquid in the cup liner and the cup, so that the water temperature is kept for a long time; when water is needed urgently or heating is needed through the cup cover, the cup is placed in an inverted mode, heat conducting liquid flows to the top of the cavity of the cup cover to be in contact with the inner container of the cup cover, the heat of liquid in the hot cup body is absorbed and vaporized, the inner cavity is filled with the heat conducting liquid, the liquid heat in the cup body is made to sequentially pass through the top of the inner container of the cup cover and be conducted to the outer cover through the heat conducting liquid gas, the liquid temperature of the cup body can be reduced rapidly, drinking is facilitated, and the outer cover is made to warm hands conveniently.
The inner cover is connected in the cup cover, and the cup opening is in threaded connection with the inner cover.
The inner cup is the cast structure who has the external screw thread, the joint has first sealing washer between inner cup and the bowl cover. The inner cover is preferably made of metal material, such as stainless steel, and is welded or bonded and clamped in the cup cover. The external thread of inner cup can play the limiting action to first sealing washer. A limiting plate can also be arranged on the cup cover or the inner cover.
The outer cover is provided with an air exhaust hole, the air exhaust hole is sealed and fixed through a rivet, and a second sealing ring is arranged between the rivet and the air exhaust hole.
The method comprises the following specific steps of vacuumizing after injecting heat-conducting liquid into a cavity in the cup cover: the heat-conducting liquid is specifically at bowl cover cavity bottom, heats the bowl cover earlier for the heat-conducting liquid vaporization, and the volume expands, discharges the air in the cavity from the aspirating hole, and the aspirating hole goes out to set up the gaseous arrival back of temperature probe perception heat-conducting liquid, then fixes the aspirating hole with rivet seal, and between with the second sealing washer sealed.
The enclosing cover is equipped with the recess, the aspirating hole sets up in the recess, and preferably, the space that can also be between rivet and recess is equipped with welding layer or glue film, strengthens the leakproofness. The top of the outer cover is connected with a top cover. The top cover shields the groove to play a role in beauty.
In other embodiments, the heat transfer medium is a heat transfer powder, including but not limited to metal powder and/or sand, and the metal powder includes single metal powder, alloy powder, or certain refractory compound powder having metallic properties.
The heat conducting powder comprises brass powder and iron sand, and the weight ratio of the brass powder to the iron sand is 1:3-3:1.
When the hot water or hot drink cup is used, hot water or hot drink is poured into the cup, the cup body is vertically and upright placed, heat conduction powder in the cavity is gathered and paved at the bottom of the cavity and is not in contact with the top of the cover liner of the cup cover and a heat source, and the hot water in the cup can be kept warm for a long time; when the urgent need drinks water or need get warm through the cup body, with the cup body upset, the vertical placing up of bottom of cup, heat conduction powder flows the cavity top of bowl cover, contacts with the lid courage top and the heat source of bowl cover for liquid heat in the cup loops through lid courage top, heat conduction powder and passes through on the enclosing cover, can reduce cup liquid temperature rapidly, conveniently drinks, or makes things convenient for the enclosing cover to warm up the hand.
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 powder is added into the cavity, the existing vacuumizing process is utilized for direct processing, and compared with vacuumizing of a vacuum cup with the empty cavity, the vacuumizing process is not changed and is not influenced. The cavity vacuumizing process is simple, the cost is low, and the high-vacuum-degree heat-preservation effect of the cavity after vacuumizing is good.
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.
