Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by simple modifications by those of ordinary skill in the art should fall within the scope of protection of the present utility model.

Example 1

As shown in Figures 1 and 3, the double-opening hand-warming thermos cup includes a cup body 1. The cup body 1 is provided with a first cup opening 2 and a second cup opening 15. The first cup opening 2 is connected to a first cup lid 19. , the second cup mouth 15 is connected to a second cup lid, which is characterized in that the second cup lid includes an outer lid 3 and a cover bladder 4 provided in the outer cover 3, the outer cover 3 and the cover bladder 4 are connected, and the outer cover 3 A closed cavity 5 is formed between the lid 4 and the cavity 5. A heat-conducting medium 6 is provided in the cavity 5. The heat-conducting medium 6 gathers at the bottom of the cavity 5 when the cup 1 is placed upright, and the surface height of the heat-conducting medium 6 is lower than Cover the height of the bottom of the bladder 4. The second cup lid has a near-vacuum double-layer structure, which can maintain the temperature of the liquid in the cup for a long time.

The heat-conducting medium 6 is heat-conducting liquid or heat-conducting powder, and the heat-conducting medium 6 can contact the cover bladder 4 and the outer cover 3 at the same time when the second cup cover is placed at an angle.

The heat transfer medium 6 is a heat transfer liquid with a boiling point of 30-100 degrees. When in use, open the first cup lid 19 or the second cup lid, pour hot water into the cup body 1, tighten the cup lid, and place it vertically. When the second cup lid cavity 5 is closed, the heat-conducting liquid or powder in the cavity 5 of the second cup lid does not come into contact with the lid bladder 4 and the high-temperature liquid in the cup, and the water temperature is maintained for a long time; when there is an urgent need to drink water or the cup lid needs to be heated, the cup body 1 When the second cup lid is tilted or shaken, the heat-conducting medium 6 can contact the top of the cover bladder 4 and the top of the outer cover 3 at the same time, or the heat-conducting medium 6 can contact the cover bladder 4 and be heated and vaporized, filling the cavity 5, so that the liquid in the cup body 1 heats up. The gas of the thermal conductive fluid is transmitted to the outer cover 3 through the lid bladder 4 and the heat transfer liquid gas in sequence, which can quickly reduce the temperature of the liquid in the cup body 1, making it easier to drink, or the outer cover 3 to warm hands.

The first cup lid 19 and the second cup lid are each provided with a sealing ring 11 inside the cup, and the cup body 1 has a double-layer structure with a vacuum inner cavity. It can keep the water temperature in the cup for a long time. The first cup opening 2 and the first cup lid 19 are connected or snap-fitted using threads 14 in the prior art. The second cup mouth 15 is the same.

The first cup lid 19 is a pop-up lid in the prior art, including a lid body 8 and a cap 7 movably arranged on the lid body 8 and a buckle 18. The lid body is connected to the first cup mouth 2, and the lid body 8 is A suction pipe 16 and a ventilation port 17 are provided.

The outer cover 3 is provided with an air extraction hole 9. The air extraction hole 9 is sealed and fixed by a rivet 10. A sealing ring 11 is provided between the rivet 10 and the air extraction hole 9.

The outer cover 3 is provided with a groove 12. The air extraction hole 9 is provided in the groove 12. The gap between the rivet 10 and the groove 12 is provided with a welding layer or a glue layer. The bottom of the outer cover 3 is connected with a bottom. Cover 13. The bottom of the outer cover 3 is provided with a depression, the groove 12 is set in the depression, and the bottom cover 13 is closed in the depression to make the outer cover 3 flush.

The specific steps for vacuuming after injecting the thermal transfer liquid into the cavity 5 of the second cup cover are: the thermal transfer liquid is specifically placed at the bottom of the cavity 5 of the second cup cover, and the second cup cover is heated first, so that the thermal transfer liquid vaporizes, the volume expands, and the cavity 5 is heated. The air in the cavity is discharged from the air extraction hole. After the temperature measuring head is installed in the air extraction hole to sense the arrival of the thermal fluid gas, the air extraction hole 9 is sealed and fixed with rivets 10, and the space between them is sealed with a sealing ring 11.

The outer cover 3 is provided with a groove 12, and the air extraction hole 9 is provided in the groove 12. Preferably, it can also be A welding layer or glue layer is provided in the gap between the rivet 10 and the groove 12 to enhance the sealing performance. A bottom cover 13 is connected to the top of the outer cover 3 . The bottom cover 13 covers the groove 12 and plays an aesthetic role.

In other embodiments, the thermally conductive medium 6 is thermally conductive powder. The thermally conductive powder includes but is not limited to metal powder and/or sand. The metal powder includes single metal powder, alloy powder or certain refractory compound powder with metallic properties.

When in use, pour hot water or hot drinks into the cup and place the cup body upright. The heat-conducting powder in the cavity 5 is gathered and laid flat on the bottom of the cavity 5 without contacting the top of the lid bladder 4 and the heat source. The hot water in the cup can be kept warm for a long time; when you need to drink water urgently or need to keep warm through the cup body, tilt the cup body, and the thermal conductive powder contacts the top of the lid bladder 4 of the cup lid and the heat source, so that the heat of the liquid in the cup body 1 passes through in sequence The heat-conducting powder of the lid bladder 4 is transmitted to the outer lid 3, which can quickly reduce the temperature of the liquid in the cup body 1, making it easier to drink, or the outer lid 3 to warm hands.

During production and processing, there are many vacuuming processes. The process is roughly divided into air extraction, sealing and welding, cooling and other links. Thermal conductive powder is added to the cavity 5 and processed directly using the existing vacuuming process. Compared with the empty cavity 5 When the thermos cup is evacuated, the vacuuming process will not change or be affected. The vacuuming process of the cavity 5 is simple and low-cost. After the vacuuming, the vacuum degree of the cavity 5 is high and the heat preservation effect is good.

The particle size of brass powder is very small, the contact area is higher, and the heat conduction is more efficient. However, when brass powder is added into the inner cavity alone, its fluidity is poor and it is easy to accumulate somewhere in the inner cavity. Iron sand or other highly fluid particles need to be added and mixed with the brass powder to make the mixed powder have high thermal conductivity. And strong liquidity.

Example 2

As shown in Figure 2, this embodiment is the same as Embodiment 1 in other places, except that the first cup lid has a double-layer structure with a vacuum inner cavity. It can keep the water temperature in the cup for a long time.
