[0029] Refer to Figure 1 and Figure 2, an electric thermos flask, comprising: a base 100, an inner container 200, a heating mechanism 500 and a cover 170. The base 100 is provided with an installation cavity 150 which has an opening 190. The inner container 200 is movably placed in the installation cavity 150, and the inner container 200 can extend into and be installed in the installation cavity 150 through the opening 190 or leave the installation cavity 150 through the opening 190. The heating mechanism 500 is arranged on the base 100, and the heating mechanism 500 can heat the inner container 200 installed in the installation cavity 150. When the inner container 200 moves away from the installation cavity 150, it can be relatively separated from the heating mechanism 500. The cover 170 is detachably installed at the opening 190 and can cover the opening 190, and the cover 170 can enclose the inner container 200 in the installation cavity 150. After the cover 170 leaves the opening 190, the liquid to be boiled can be poured into the inner container 200 through the opening 190; or, after the inner container 200 loaded with the liquid to be boiled is installed into the installation cavity 150, the cover 170 can be installed at the opening 190, and the inner container 200 can be enclosed in the installation cavity 150. Subsequently, when the heating mechanism 500 is started, the liquid in the inner container 200 can be cooked. When the inner container 200 needs to be cleaned, the inner container 200 can be taken out of the installation cavity 150 and the inner container 200 can be cleaned separately. Since the inner container 200 will be relatively separated from the heating mechanism 500 when it leaves the installation cavity 150, it can effectively avoid the influence of the cleaning process on the heating mechanism 500 when the inner container 200 is taken out and cleaned separately. And, since the separation of the inner container 200 and the heating mechanism 500 can be achieved directly by taking out the inner container 200 without disassembling between the inner container 200 and the heating mechanism 500, and when the inner container 200 is cleaned, there is no need to worry about damaging the heating mechanism 500, so the cleaning operation of the inner container 200 can be carried out more simply and conveniently, thus effectively improving the use and cleaning experience of the electric thermos flask.

[0030] In some embodiments, referring to Figure 2 , the heating mechanism 500 is arranged at the bottom of the installation cavity 150, and when the inner container 200 is installed in the installation cavity 150, it can be in contact with the heating mechanism 500. During the process of the inner container 200 entering the installation cavity 150, it will be in contact with the heating mechanism 500. Therefore, the heat emitted by the heating mechanism 500 can be smoothly transferred to the inner container 200, thereby heating the inner container 200 and the liquid loaded therein, and then the cooking operation can be completed.

[0031] It can be envisioned that the heating mechanism 500 can also be arranged at other parts of the installation cavity 150, such as surrounding the side of the installation cavity 150. Therefore, the specific implementation manner is not unique, but can be adjusted according to the actual situation and is not limited here.

[0032] In some embodiments, referring to Figure 2 , the heating mechanism 500 is fixed within the base 100 and extends to the bottom of the installation cavity 150. The open end 190 is located at the top of the base 100. Only when the inner container 200 is installed in the installation cavity 150, the heating mechanism 500 contacts the inner container 200 and heats it. During the process of the inner container 200 entering the installation cavity 150, it will gradually move from the top of the installation cavity 150 to the bottom of the installation cavity 150 and finally contact the heating mechanism 500. The positional distribution between the open end 190 and the heating mechanism 500 can effectively prevent the heating mechanism 500 from contacting the inner container 200 before the inner container 200 completely enters the installation cavity 150. Therefore, it can effectively reduce the possibility that the user is injured by the heat dissipated by the heating mechanism 500 when putting the inner container 200, and thus effectively improve the safety of using the electric thermos.

[0033] In some embodiments, referring to Figure 6 , the heating mechanism 500 includes an electric hot plate 530 installed within the base 100, and the electric hot plate 530 is fixed to the bottom of the installation cavity 150. When the electric hot plate 530 is powered on, it can emit heat and heat the inner container 200 and the liquid contained therein through the heat, so as to directly and effectively perform cooking operations.

[0034] It can be envisioned that the heating mechanism 500 can also be composed of other components, such as a gas burner. The specific implementation manner is not unique and can be adjusted according to actual needs, and is not limited herein.

[0035] In some embodiments, referring to Figure 6 , at least a part of the electric hot plate 530 extends into the installation cavity 150 and can contact the inner container 200. The part of the electric hot plate 530 extending into the installation cavity 150 can directly contact the inner container 200, thereby directly heating the inner container 200, and can effectively avoid heat loss during heat transfer in the intermediate component, and thus can effectively improve the heating efficiency.

[0036] It can be envisioned that the electric hot plate 530 can also be arranged outside the installation cavity 150 and conduct heat through the installation cavity 150. The specific implementation manner can be adjusted according to actual needs and is not limited herein.

[0037] In some embodiments, referring to Figure 2, a water delivery pipe and a connection valve 570 are arranged inside the machine base 100. The connection valve 570 can be butted with the inner container 200 extending into the installation cavity 150. The connection valve 570 is used to connect the water delivery pipe and the inside of the inner container 200 or disconnect the connection therebetween. After the inner container 200 is installed in the installation cavity 150, the connection valve 570 can connect the inside of the inner container 200 and the water delivery pipe, so that water can flow out of or into the inner container 200. Thus, it can make the operation of replenishing or discharging water in the inner container 200 more convenient, and further make the electric thermos more easy to use.

[0038] In some embodiments, referring to Figure 3 and Figure 5 , a butting part 230 is arranged on the outer wall of the inner container 200. The connection valve 570 is provided with a valve cavity 575, and the water delivery pipe is communicated with the valve cavity 575; the connection valve 570 can be butted with the butting part 230 and make the valve cavity 575 communicate with the inside of the inner container 200; a temperature detector 571 is arranged in the valve cavity 575, and the temperature detector 571 is electrically connected with the electric hot plate 530. After the connection valve 570 is butted with the inner container 200 and makes the valve cavity 575 and the inside of the inner container 200 communicate, the liquid in the inner container 200 will flow into the valve cavity 575 and contact with the temperature detector 571, so that the temperature of the liquid to be cooked inside the inner container 200 can be detected, and the heating mechanism 500 can be turned off when the temperature of the liquid to be cooked inside the inner container 200 exceeds a predetermined value. Therefore, it can effectively avoid the situation that the temperature of the inner container 200 is too high and the corresponding safety problems.

[0039] In some embodiments, referring to Figure 3, the docking part 230 is provided with a first opening 237, a first plug part 233 and a first spring 232. The first spring 232 is connected to the first plug part 233 and can be pushed to move to block the first opening 237; a second opening 577, a second plug part 573 and a second spring 572 are arranged in the connection valve 570. The second spring 572 is connected to the second plug part 573 and can be pushed to move to block the second opening 577; when the connection valve 570 is docked with the docking part 230, the docking part 230 can move through the second opening 577 and make the first opening 237 extend into the valve cavity 575. When the docking part 230 is docked with the connection valve 570, a part of the docking part 230 will extend into the valve cavity 575 of the connection valve 570 and make the first opening 237 enter the valve cavity 575. At this time, under the action of the force of switching or other actions, the first plug part 233 can be driven to leave the first opening 237, and the second plug part 573 can be driven to leave the second opening 577, so that the valve cavity 575 is communicated with the inside of the inner tank 200 through the docking part 230, and then it is convenient for the liquid to enter the valve cavity 575 from the inside of the inner tank 200 and the temperature detector 571 to detect the temperature. When the inner tank 200 is taken out of the installation cavity 150, the first spring 232 will drive the first plug part 233 to move to the first opening 237 by elastic force and block the first opening 237, and the second spring 572 will drive the second plug part 233 to move to the second opening 577 by elastic force and block the second opening 577. Thus, when the inner tank 200 is taken out, both the inner tank 200 and the valve cavity 575 will be in a closed state, so the problem of leakage can be effectively avoided.

[0040] Specifically, when the docking part 230 gradually extends into the valve cavity 575, it will push the second plug part 573, so that the second plug part 573 can be made to leave the second opening 577. When the docking part 230 further extends into the valve cavity 575, the temperature detector 571 will push the first plug part 233, so that the first plug part 233 leaves the first opening 237. Thus, both the first opening 237 and the second opening 577 will be opened during the process of the docking part 230 extending into the valve cavity 575, so as to achieve the effect of communicating the inside of the inner tank 200 and the valve cavity 575. Of course, the first plug part 233 and the second plug part 573 can also be driven in other ways, such as being driven by electric components. The specific implementation manner is not unique and can be adjusted according to actual needs, which will not be limited here.

[0041] Furthermore, sealing components are arranged in both the valve cavity 575 and the docking part 230 to ensure that during the process of the docking part 230 extending into the valve cavity 575, the fluid will not flow out from the gap between the valve cavity 575 and the docking part 230.

[0042] In some embodiments, refer to Figure 4, a handle 210 is provided on the side of the inner container 200. When the inner container 200 is installed in the installation cavity 150, at least part of the handle 210 is located outside the installation cavity 150. The handle 210 can provide a gripping position on the inner container 200 that is convenient for the user to apply force, so that the user can smoothly drive the inner container 200 to move into or out of the installation cavity 150 through the handle 210, and thus the inner container 200 can be more conveniently taken, placed, and used.

[0043] In some embodiments, referring to Figure 4 , the machine base 100 is provided with a receiving groove 105. The receiving groove 105 is located on the side of the opening 190, and the handle 210 can be installed in the receiving groove 105. The receiving groove 105 can not only load the handle 210, but also achieve the mutual positioning effect between the machine base 100 and the inner container 200 through the installation between the receiving groove 105 and the handle 210, so that the inner container 200 can be stably installed in the installation cavity 150 without shaking or moving during cooking.

[0044] In some embodiments, referring to Figure 1 , a buckle is provided between the cover 170 and the machine base 100 and can be connected and fixed through it. The buckle can snap and fix the cover 170 to the machine base 100, so as to ensure that the cover 170 can firmly fix between the machine base 100 and the inner container 200 and prevent the inner container 200 from shaking during cooking.

[0045] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0046] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
