[0037] As shown in Figure 4 , the piercing assembly in the lower cup 2 is used to pierce the sealing film on the water bag 4, the piercing assembly in the lower cup 2 comprises a mounting block 16 and a piercing knife 12 fixed at the end of the mounting block 16, the piercing knife 12 of the piercing assembly in the lower cup 2 is located at the upper side of the self-heating bag 5, the piercing knife 12 of the piercing assembly in the lower cup 2 faces the upper side; there is a gap between the inner side wall of the lower cup 2 and the piercing knife 12, so that the upper cup 1 can contact the sealing film on the water bag 4 in the upper cup 1 when the upper cup 1 and the lower cup 2 are close to each other.

[0038] In this embodiment, in order to place the self-heating bag 5 in the lower cup 2 from top to bottom, a slot 14 (as shown in Figure 6 ) is provided at the upper end of the self-heating bag 5 for the piercing assembly to pass through, and a plurality of fifth limiting blocks 11 are circumferentially arranged on the inner side wall of the lower cup 2 and contact the lower end surface of the sealing film of the self-heating bag 5. In another implementation, the reactants in the self-heating bag 5 can be directly placed in the lower cup 2, and then the opening of the lower cup 2 can be directly plastic sealed.

[0039] Referring to Figure 1 , the upper and lower positions of the upper cup 1 relative to the lower cup 2 are adjustable; the upper end of the lower cup 2 is provided with an extension 6, the extension 6 extends into the upper cup 1 and is threadedly connected with the upper cup 1. In another implementation, the outer side wall of the extension 6 contacts the inner side wall of the upper cup 1, and the extension 6 can slide in the upper cup 1.

[0040] When the extension 6 is threadedly connected with the upper cup 1. In order to ensure that the piercing knives 12 in the upper cup 1 and the lower cup 2 do not interfere with each other, in the initial position, the piercing knife 12 in the upper cup 1 and the piercing knife 12 in the lower cup 2 are on the same side, when the lower cup 2 or the upper cup 1 is rotated, the piercing knives 12 in the upper cup 1 and the lower cup 2 are away from each other, and the pitch of the thread is controlled to ensure that the piercing knives 12 can pierce the water bag 4 and the self-heating bag 5 before one rotation.

[0041] Referring to Figure 2The sixth limiting block 13 is fixed to the inner side of the upper cup body 1 and is located at the lower side of the thread in the upper cup body 1, so that the lower cup body 2 cannot be separated from the upper cup body 1. The lower cup body 2 is made of elastic material and can be slightly deformed when entering the upper cup body 1. Therefore, the extension 6 of the lower cup body 2 can directly enter the upper side of the sixth limiting block 13 of the upper cup body 1 after being pressed, and the lower cup body 2 cannot be easily separated from the upper cup body 1. In another embodiment, the sixth limiting block 13 can be directly provided in a ring shape, which has a better limiting effect.

The inner wall of the circular frustum segment is further provided with a plurality of limiting blocks 18 in the circumferential direction. The limiting blocks 18 cooperate with the second limiting member to limit the to-be-heated container 3, preventing the to-be-heated container 3 from moving. Meanwhile, the inner wall of the circular frustum segment can also cooperate with the tapered surface of the to-be-heated container 3 to limit the to-be-heated container 3.

[0043] The upper end of the first cylindrical segment is fixed with a flange 17, which can be clamped to the inner side of the top edge of the to-be-heated container 3. When people drink hot drinks, the lips will contact the flange 17, which can prevent the mouth from being scalded and form a downward limiting for the to-be-heated container 3, avoiding the to-be-heated container from moving up and down. The to-be-heated container 3 can be a pop-top can containing beverages or rice pudding and other foods, or an open beverage cup.

[0044] The installation process of the device is as follows: first, the water bag 4 is put into the upper cup body 1 through the upper opening of the upper cup body 1. The water bag is limited by the first limiting member to the upper side of the piercing assembly of the upper cup body 1. Then, the extension 6 of the lower cup body 2 provided with the self-heating bag 5 is clamped into the upper cup body 1. Then, the to-be-heated container 3 is put into the upper cup body 1, and the lower end of the to-be-heated container 3 is limited by the second limiting member. Then, the cover 15 is screwed to the upper side of the upper cup body 1, and the cover 15 cooperates with the second limiting member to limit the to-be-heated container 3.
