[0041] When people are outdoors, they often need to carry drinking water. However, current beverage cups are very difficult to keep warm for a long time when used outdoors. In this way, it is very difficult for people to drink hot water when going out for a long time, such as traveling or having a picnic. Therefore, it is very unfavorable for people's travel.

[0042] In view of this, the present invention provides a self-heating and heat-preserving device dedicated for beverages, aiming to solve the problem that beverages cannot be kept warm for a long time during outdoor activities. Among them, Figure 1 is a schematic cross-sectional structure diagram of an embodiment of the self-heating and heat-preserving device dedicated for beverages provided by the present invention; Figure 2 is Figure 1 a schematic exploded structure diagram of the housing (partial structure), water guide pipe, self-heating strip and self-heating package in Figure 3 is Figure 1 a schematic enlarged structure diagram of part A (when the expansion structure is not expanded) in Figure 3 is Figure 1 a schematic enlarged structure diagram of part A (when the expansion structure is expanded) in

[0043] Please refer to Figures 1 to 4, the dedicated self-heating and heat-preserving device 100 for beverages includes a housing 1, a self-heating strip 2, and a water control structure 3. The housing 1 is formed with a water injection cavity 11 and a heating cavity 12 that are distributed in sequence from top to bottom. A water guide pipe 4 is communicatively provided between the water injection cavity 11 and the heating cavity 12. The heating cavity 12 is used to accommodate a beverage water cup. The self-heating strip 2 extends in the vertical direction and is disposed on the inner wall of the heating cavity 12, and the upper end of the heating strip is wrapped around the water guide pipe 4. The self-heating strip 2 can gradually generate heat from top to bottom under the penetration of water in the water guide pipe 4, and is used to be attached to the side wall of the beverage water cup. The water control structure 3 is used to control the water flow rate in the water guide pipe 4 according to the temperature in the heating cavity 12.

[0044] Among them, it should be explained that the water control structure 3 is used to control the water flow rate in the water guide pipe 4 according to the temperature in the heating cavity 12, and there are various specific implementation methods. For example, a temperature sensor can be provided in the heating cavity 12, and a flow control valve can be provided on the water guide pipe 4. By feedback control of the temperature sensor to the opening degree of the flow control valve, the water flow rate can be controlled according to the height of the temperature. The self-heating strip 2 can undergo a chemical reaction when encountering water to release heat. Its specific structure generally includes an outer packaging net and a filler. The filler can be made of various materials. For example, it can include calcium oxide, aluminum powder, sodium bicarbonate, diatomaceous earth, coke powder, etc. The self-heating strip 2 is strip-shaped and extends in the vertical direction. During the process of water gradually penetrating the self-heating strip 2 from top to bottom, the self-heating strip 2 can gradually release heat until the entire self-heating strip 2 has completed the reaction. The reaction duration depends on the water flow rate of the water guide pipe 4.

[0045] In the technical solution provided by the present invention, after the beverage water cup is placed into the heating cavity 12, water is injected into the water injection cavity 11. Under the action of gravity, the water guide pipe 4 will introduce the water into the self-heating strip 2. Under the penetration of water, a chemical reaction occurs in the self-heating strip 2, thereby releasing heat outward to heat the beverage water cup. During the process of the temperature rising in the heating cavity 12, the water control structure 3 can control the water flow rate in the water guide pipe 4 to different extents according to different temperatures. On the premise that the water flow rate is controlled, the heat generation rate of the self-heating strip 2 is also controlled, so as to gradually release heat slowly from top to bottom, so as to realize the heating and long-term heat preservation of the beverage water cup.

[0046] Since the self-heating strip 2 needs to be installed on the inner wall of the heating cavity 12 and needs to be relative to the water guide pipe 4 so that the water guide pipe 4 can continuously introduce water into the self-heating strip 2, it is necessary to keep the position of the self-heating strip 2 fixed. In view of this, please refer to Figure 1, in this embodiment, a receiving groove is formed on the inner wall of the heating cavity 12, and the self-heating strip 2 is inserted into the receiving groove. By providing the receiving groove, on the one hand, the self-heating strip 2 can be received, and under the squeezing action of the beverage water cup, the self-heating strip 2 can be fixed and limited in the receiving groove, so that the position of the self-heating strip 2 remains relatively fixed, so that the self-heating strip 2 can stably wrap the water guide pipe 4, ensuring the continuous progress of the chemical reaction in the self-heating strip 2. On the other hand, the self-heating strip 2 can also be replaced to realize the repeated use of the special self-heating and heat-preserving device 100 for beverages.

[0047] There are various forms of the control mode of the water flow rate in the water guide pipe 4 by the water control structure 3. Specifically, in this embodiment, the water guide pipe 4 is elastically arranged and includes a water control pipe section located in the heating cavity 12; the water control structure 3 includes an expansion structure 31, the expansion structure 31 is arranged on the top wall of the water injection cavity 11 and corresponds to the water control pipe section, and the expansion structure 31 can squeeze the water control pipe section with a corresponding expansion degree in different temperature environments to control the water flow rate in the water control pipe section. Among them, the elastic arrangement of the water guide pipe 4 means that the water guide pipe 4 can deform under the external squeezing action, thereby changing the cross-section of the internal water guide channel, and further realizing the effect of controlling the water flow rate according to the magnitude of the external squeezing force; the expansion structure 31 can expand to different degrees according to the temperature, thereby applying different magnitudes of squeezing forces to the water control pipe section, and further realizing the control of the water flow rate in the water guide pipe 4 according to the temperature. With such a setting, the structure is relatively simple, and only the size of the expansion structure 31 needs to be reasonably set, and the material of the expansion structure 31 is correspondingly selected to ensure that the expansion structure 31 can squeeze the water control pipe section to a corresponding degree within a certain temperature range. For example, within the temperature range above 70°C, the expansion structure 31 can effectively act on the water control pipe section, and when the temperature reaches 100°C, the expansion structure 31 can completely squeeze and close the water control pipe section to cut off the downstream flow of water and stop unnecessary heat generation, effectively extending the heat preservation duration.

[0048] The number of the self-heating strips 2 provided can be one or more. Specifically, in this embodiment, the water guide pipe 4 and the self-heating strip 2 form a water injection and heating group in one-to-one correspondence, and multiple groups of the water injection and heating groups are provided and distributed along the circumferential direction of the heating cavity 12. By providing multiple groups of the water injection and heating groups, the beverage water cup can be heated simultaneously from the circumferential direction of the heating cavity 12, improving the heating efficiency of the beverage water cup. At the same time, the heating efficiency of a single self-heating strip 2 can also be reduced, thereby multiplying the heat preservation duration of the special self-heating and heat-preserving device 100 for beverages.

[0049] Furthermore, in this embodiment, the multiple water guide pipes 4 include multiple long water guide pipes 42 and multiple short water guide pipes 41. Correspondingly, the multiple self-heating strips 2 include long heating strips 21 and short heating strips 22. Among them, after placing the drink water cup, the bottom position heights of the long water guide pipe 42 and the short water guide pipe 41 are aligned with the bottom of the drink water cup, and there is a height difference between them in the height of the drink water cup. That is, under the water guiding action of the corresponding long water guide pipe 42 and short water guide pipe 41 respectively, the long heating strip 21 can start to react and generate heat downward from the top side of the drink water cup to heat and keep warm the upper-layer beverage in the drink water cup, while the short heating strip 22 can start to heat downward from the middle side of the drink water cup to heat and keep warm the middle-layer beverage in the drink water cup. Generally speaking, the beverage in the drink water cup can be evenly heated, and the user can then take it out and drink it without waiting for the heat to evenly diffuse, improving the user experience.

[0050] Even further, in this embodiment, the multiple long heating strips 21 and the multiple short heating strips 22 are arranged at intervals one by one. Correspondingly, the multiple short water guide pipes 41 and the multiple long water guide pipes 42 are arranged at intervals one by one. By arranging the multiple long heating strips 21 and the multiple short heating strips 22 at intervals one by one, the drink water cup can be evenly heated from all directions on the periphery from high and middle positions, further improving the effect of uniform heating.

[0051] Since the heating cavity 12 is located below the water injection cavity 11, therefore, the drink water cup can only be loaded into the heating cavity 12 from the side or below. Since the self-heating strip 2 is installed on the inner wall of the heating cavity 12, this makes it difficult to implement the solution of taking and placing the drink water cup from the side. In view of this, in this embodiment, the drink special self-heating and heat-preserving device 100 further includes a bottom cover 6, and the bottom cover 6 is detachably arranged at the bottom of the housing 1 to cover the heating cavity 12. Among them, there are various situations for the detachable setting of the bottom cover 6 on the housing 1. For example, the disassembly and assembly of the bottom cover 6 and the housing 1 can be realized through a zipper structure, or the disassembly and assembly of the bottom cover 6 and the housing 1 can be realized through a buckle structure. This embodiment does not limit this; by setting the bottom cover 6, the heating cavity 12 can be set to open downward, so that the drink water cup can be loaded into the heating cavity 12 from bottom to top, without being affected by the installation position of the self-heating strip 2.

[0052] Further, in this embodiment, a self-heating pack 7 is provided on the bottom cover 6. The self-heating pack 7 is disposed corresponding to the bottom of the self-heating strip 2 and is used to be adhered to the bottom wall of the drink water cup. Since the self-heating pack 7 is disposed corresponding to the bottom of the self-heating strip 2, after the exothermic reaction of the self-heating strip 2 with water is completed, the water can seep downward from the self-heating strip 2 and thus enter the self-heating pack 7. Thereafter, the self-heating pack 7 can continue to exotherm when encountering water to heat and keep warm the drink water cup from the bottom, further improving the heat preservation duration of the self-heating and heat preservation device 100 for drinks.

[0053] Furthermore, in this embodiment, a receiving groove is formed on the bottom cover 6, and the self-heating pack 7 is installed in the receiving groove. In this way, the self-heating pack 7 can be limited to prevent deviation, ensuring the heat preservation effect.

[0054] To improve the heat preservation effect of the self-heating and heat preservation device 100 for drinks and reduce heat dissipation, in this embodiment, the housing 1 further includes a heat preservation layer 5, and the heat preservation layer 5 is disposed to cover the periphery of the housing 1. Through the setting of the heat preservation layer 5, on the one hand, it can effectively achieve the heat preservation effect, and on the other hand, it can also improve the support effect so that a handle or a strap structure can be provided with the heat preservation layer 5 as the base, thus facilitating the user to carry.

[0055] In addition, to achieve the above object, the present invention further provides a usage method of the self-heating and heat preservation device 100 for drinks. The self-heating and heat preservation device 100 for drinks includes a housing 1, a self-heating strip 2, and a water control structure 3. The housing 1 is formed with a water injection cavity 11 and a heating cavity 12 that are distributed in sequence from top to bottom. A water guide pipe 4 is communicatively provided between the water injection cavity 11 and the heating cavity 12. The heating cavity 12 is used to accommodate a drink water cup; the self-heating strip 2 extends in the vertical direction on the inner wall of the heating cavity 12, and the upper end of the heating strip is covered by the water guide pipe 4. The self-heating strip 2 can gradually generate heat from top to bottom under the soaking of the water in the water guide pipe 4 and is used to be adhered to the side wall of the drink water cup; the water control structure 3 is used to control the water flow in the water guide pipe 4 according to the temperature in the heating cavity 12; a receiving groove is formed on the inner wall of the heating cavity 12, and the self-heating strip 2 is inserted into the receiving groove; the self-heating and heat preservation device 100 for drinks further includes a bottom cover 6, and the bottom cover 6 is detachably disposed at the bottom of the housing 1 to cover the heating cavity 12; a self-heating pack 7 is provided on the bottom cover 6, and the self-heating pack 7 is disposed corresponding to the bottom of the self-heating strip 2 and is used to be adhered to the bottom wall of the drink water cup;

[0056] The usage method of the self-heating and heat preservation device 100 for drinks includes the following steps

[0057] Open the bottom cover 6, insert the self-heating strip 2 into the receiving groove, and load the self-heating pack 7 onto the bottom cover 6 so that the self-heating strip 2 wraps the water guide pipe 4;

[0058] Wherein, a concave portion corresponding to the water guide pipe 4 is formed at the upper end of the self-heating strip 2, so that the water guide pipe 4 can be adaptively inserted into the self-heating strip 2 to prevent moisture from flowing downward along the outside of the self-heating strip 2 and causing waste of moisture.

[0059] After inserting the beverage water cup into the heating cavity 12, close the bottom cover 6 so that the self-heating pack 7 abuts against the self-heating strip 2;

[0060] Wherein, after closing the bottom cover 6, the self-heating pack 7 can abut against the self-heating strip 2. On the one hand, it can play a limiting role on the self-heating strip 2, and on the other hand, it can also receive the moisture flowing out of the self-heating strip 2, so as to continue the reaction and release heat.

[0061] Inject water into the water injection cavity 11.

[0062] Wherein, after the water injection is completed, the water can spontaneously flow into the self-heating strip 2 along the water guide pipe 4, thereby autonomously starting the heating and heat preservation process.
