Description

A direct drink thermos cup

technical field

The invention relates to the technical field of daily necessities, in particular to a thermos cup for direct drinking.

Background technique

The thermos cup is a cup that achieves heat insulation through the vacuum layer between the inner liner and the cup body, so that the water and other liquids in the inner liner can delay the heat dissipation, so as to achieve the purpose of heat preservation. Of course, there are also some thermos cups on the market that achieve thermal insulation through materials such as ceramics. When water or other liquids are boiled and poured into the thermos cup, the temperature of the liquid in the inner tank remains high for a long time. When the user drinks, it is necessary to pour water and other liquids out of the thermos cup to slowly cool it to room temperature, which takes a long time for the user to wait. That is to say, although the existing thermos cups can satisfy the heat preservation function of the liquid contained in them, the excessive heat preservation effect prevents the water temperature from being rapidly lowered, making it impossible for people to drink freely.

SUMMARY OF THE INVENTION

In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a direct-drinking thermos cup with ingenious structural design, which can not only heat the contained solution but also rapidly cool down during drinking.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical solutions:

A direct-drinking thermos cup is characterized in that it comprises a thermos cup body with a water injection port at one end and a cup sleeve sleeved on the outside of the thermos cup body, the thermos cup body comprises a cup wall for heat preservation and heat insulation, so A first cavity that communicates with the water injection port is formed in the cup wall; one end of the cup sleeve is sealed with the cup wall, and a second cavity is formed at an interval between the two, and the other end of the cup sleeve is formed. is a drinking port communicating with the second cavity; the cup wall has a water outlet that communicates with the first cavity and the second cavity, and the water outlet is located at the bottom of the second cavity; It also includes a first cup cover matched with the water injection port.

When using, first open the lid of the first cup, pour the hot water into the first cavity from the water injection port, then cover the first cup cover on the water injection port, and place the drinking port of the thermos cup upwards. The hot water flows into the second cavity through the water outlet. Since the second cavity is formed by the gap between the cup wall and the cup sleeve, the volume of the second cavity is relatively small. Once the hot water flows into the second cavity, the volume is small. There is a large contact area between the hot water and the cup sleeve, so that the heat exchange with the cup sleeve can be performed faster. On the other hand, due to the thermal insulation effect of the cup wall, the hot water in the first cavity and the second cavity can only conduct slower and less heat exchange through the water outlet holes, and the hot water in the second cavity and the The heat exchange speed of the hot water in the first cavity is slow, and the heat exchange speed with the cup sleeve is faster, so that the hot water entering the second cavity can be quickly cooled by heat exchange with the cup sleeve before being drunk into the mouth , to realize that the thermos cup can be opened at any time to drink at any time.

One end of the first vent hole communicates with the second vent hole, and the other end communicates outward along the valve core.

Since the second vent hole is close to the inward end of the valve core, when drinking water, the bottom of the cup wall faces upward, and the valve core moves into the first cavity under the action of gravity, so that the second vent hole slides out of the vent hole, so that the The air in the first cavity communicates with the outside through the second ventilation hole and the second ventilation hole. When injecting water, the water injection port is upward, the bottom of the cup wall is downward, the valve core moves out of the first cavity under the action of gravity, the second ventilation hole slides into the ventilation hole, and the second ventilation hole is covered by the hole wall of the ventilation hole. Therefore, the water in the first cavity can be blocked from flowing out through the air-permeable one-way valve.

Further, one end of the valve core facing inward protrudes radially outward, and the other end is connected with a counterweight.

In this way, the valve core can be prevented from completely slipping out of the vent hole, and the valve core can be reliably slid in place in the vent hole by using the counterweight.

Further, the cup sleeve and the cup wall are detachably connected through threads.

Due to the long-term use of the vacuum flask, scale or tea scale may form in the first cavity and the second cavity. The scale or tea scale in the first cavity can be cleaned through the water injection port, while the second cavity has a narrow space. Inconvenient to clean. The cup sleeve and the cup wall are designed to be detachably connected by threads, and when the second cavity needs to be cleaned, the cup sleeve and the cup wall can be separated, and the inner wall of the cup sleeve and the outer wall of the cup wall can be cleaned.

Further, the cup wall is folded radially outward at the water injection port, and extends downward to form an annular flange, and the annular flange is provided with an internal thread; Internal thread to match external thread.

Further, the cup wall includes an inner layer and an outer layer arranged in a nest, and the inner layer and the outer layer are hermetically connected to form a vacuum cavity.

The hot water flows into the second cavity through the water outlet. Since the second cavity is formed by the gap between the cup wall and the cup sleeve, the volume of the second cavity is relatively small. Once the hot water flows into the second cavity, the volume is small. There is a large contact area between the hot water and the cup sleeve, so that the heat exchange with the cup sleeve can be performed faster. On the other hand, due to the thermal insulation effect of the cup wall, the hot water in the first cavity and the second cavity can only conduct slower and less heat exchange through the water outlet holes, and the hot water in the second cavity and the The heat exchange speed of the hot water in the first cavity is slow, and the heat exchange speed with the cup sleeve is faster, so that the hot water entering the second cavity can be quickly cooled by heat exchange with the cup sleeve before being drunk into the mouth , to realize that the thermos cup can be opened at any time to drink at any time. In addition, when not drinking water, the hot water in the first cavity will not continue to flow into the second cavity, so that the heat preservation function can be achieved by the wall of the cup.

Specifically, in this embodiment, the end of the cup sleeve 2 facing the water injection port is sealed with the cup wall 11, and the end of the cup wall 11 away from the water injection port is located in the drinking port; the A second cup cover 6 is provided on the drinking port in an openable manner.

When pouring water, close the second cup cover on the drinking port with the water injection port facing upwards, open the first cup cover, pour hot water into the first cavity, and then close the first cup cover on the water injection port. Since the water outlet hole is located at the bottom of the second cavity, in this structure, the bottom of the second cavity is close to the water injection port, that is, the water outlet hole 4 is located near the water injection port, as shown in FIG. 2 . When the water injection port is placed upward, the hot water in the first cavity cannot flow into the second cavity through the water outlet hole, so as to ensure a better thermal insulation effect; and when drinking water, turn the thermos cup over, as shown in Figure 3.

Hot water to cool down.

As shown in FIG. 4 , the bottom of the cup wall 11 has a ventilation hole 9 communicating with the second cavity.

Since the bottom of the cup wall is in the same direction as the drinking port, when drinking water, the bottom of the cup wall faces upwards, the hot water in the first cavity flows into the second cavity through the water outlet hole, and the air enters the second cavity through the ventilation hole. The air pressure in the second cavity is consistent with the atmospheric pressure, so that the hot water can flow out from the water outlet more easily.

After the ventilation hole 9 is provided, when the water injection port is placed upward, the hot water in the first cavity flows into the first cavity through the ventilation hole 9, which will affect the thermal insulation effect and easily cause the hot water to stay in the second cavity for a long time. Cooling, affects drinking experience. To this end, in this embodiment, the ventilation hole is further set in a cylindrical shape, and a ventilation check valve 7 is installed. The ventilation check valve 7 includes a The valve core 71, the diameter of the valve core 71 is consistent with the diameter of the ventilation hole; the valve core 71 has a first ventilation hole arranged in the axial direction and a second ventilation hole arranged in the radial direction. The second vent hole is close to the inward end of the valve core 71 , one end of the first vent hole communicates with the second vent hole, and the other end communicates outward along the valve core 71 .

Since the second vent hole is close to the inward end of the valve core, when drinking water, the bottom of the cup wall faces upward, and the valve core moves into the first cavity under the action of gravity, so that the second vent hole slides out of the vent hole, so that the The air in the first cavity communicates with the outside through the second ventilation hole and the second ventilation hole. When injecting water, the water injection port is upward, the bottom of the cup wall is downward, the valve core moves out of the first cavity under the action of gravity, the second ventilation hole slides into the ventilation hole, and the second ventilation hole is covered by the hole wall of the ventilation hole. Therefore, the water in the first cavity can be blocked from flowing out through the air-permeable one-way valve.

Specifically, an inward end of the valve core 71 protrudes radially outward, and a counterweight 72 is connected to the other end.

In this way, the valve core can be prevented from completely slipping out of the vent hole, and the valve core can be reliably slid in place in the vent hole by using the counterweight.

Due to the long-term use of the vacuum flask, scale or tea scale may form in the first cavity and the second cavity. The scale or tea scale in the first cavity can be cleaned through the water injection port, while the second cavity has a narrow space. Inconvenient to clean. To this end, in this embodiment, the cup sleeve 2 and the cup wall 11 are also detachably connected by threads.

In specific implementation, in order to improve the sealing effect, a sealing ring can also be arranged in the flange, so that when the cup sleeve 2 is screwed into the flange, the sealing ring can be squeezed to achieve sealing.

In order to allow the hot water to cool down more quickly when it flows through the second cavity, it is necessary to make the outer surface of the cup sleeve and the cup wall have a relatively low temperature, so that the hot water can make full use of the temperature difference and the large contact area to quickly heat up exchange. To ensure that the outer surface of the cup wall has a relatively low temperature, the cup wall 11 needs to have a good thermal insulation effect. To this end, in this embodiment, the cup wall 11 includes an inner layer and an outer layer that are nested, and the inner layer and the outer layer are hermetically connected to form a vacuum chamber. The temperature between the inner layer and the outer layer of the cup wall is isolated by the vacuum chamber, so that good heat insulation can be achieved, which can not only improve the heat preservation effect, but also obtain better cooling performance.

In order to satisfy consumers' tea drinking habits and prevent tea leaves and other infusions from blocking the water outlet, a detachable filter screen 8 is also provided in the cup wall 11 .

In the solution of the present invention, the thermal insulation of the cup wall is mainly used to realize the isolation of the first cavity and the second cavity, and at the same time, the narrow space of the second cavity is used to increase the ratio of the heat dissipation surface area to the volume of the outflowing hot water, so as to dissipate heat. The larger the ratio of surface area to volume, the more heat exchange can be performed under the same conditions. Therefore, to control the ratio of surface area to volume of hot water in the second cavity, it is necessary to control the gap between the cup sleeve 2 and the cup wall 11. size, the larger the gap, the more hot water the second cavity can hold, and the smaller the ratio of heat dissipation surface area to volume; the smaller the gap between the two, the less hot water the second cavity can hold, and the larger the heat dissipation surface area to volume ratio .

In order to satisfy the consumption of each sip of water by consumers, in this embodiment, the gap between the cup sleeve 2 and the cup wall 11 is controlled within 3 mm. In this way, not only can the hot water enter the second cavity to quickly cool down, but also the drinking water demand of consumers can be met.

In addition, the speed of heat exchange is also related to the temperature difference between the heat exchange substances, and also to the specific heat capacity of the two. Since the cup sleeve and the cup wall are detachably connected together by threads in this embodiment, it can be replaced by replacing different materials. Cup sleeve, that is, to replace the cup sleeve with different specific heat capacity. For example, the cup cover 2 can be made of stainless steel, glass, ceramics, purple sand, copper or silver, etc., or the cup cover 2 can be arranged in two layers, including an inner cup cover and an outer cup cover, and between the two The airtight cavity formed by the gap between them is filled with air, water or phase change material.

In actual use, the detachable cup cover can not only adjust the gap between the cup cover and the cup wall to meet the needs of different groups of people drinking water per sip, but also adjust the cup cover of different materials to meet the needs of cooling speed adjustment , and can also replace different styles of cup sleeves, allowing consumers to replace different cup sleeves for different seasons or for different drinks or different moods, to meet the multi-level needs of usability, applicability and personality.

The main function of the thermos cup is to keep the stored solution within a certain temperature range for a long time.
