Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1 and 2, the liquid heater comprises a foldable inner container 3, an upper shell 1 and a bottom shell 2, wherein the inner container 3 is cylindrical, the upper part of the inner container 3 is connected with the upper shell 1, and the lower part of the inner container 3 is connected with the bottom shell 2. When the folding is needed, the user presses the upper shell 1 to drive the inner container 3 to fold, so that the bottom shell 2 is stored in the upper shell 1. Wherein, the inner container 3 is made of soft silica gel. In other embodiments, the upper shell 1 can be accommodated in the bottom shell 2, and the inner container 3 is supported by a hard material and can be folded.

The lower end of the upper shell 1 is provided with an opening 5 for accommodating the inner container 3, the inner container 3 is provided with a connecting layer 311, the upper end of the connecting layer 311 is connected in the upper shell 1, and the upper shell 1 shields the connection between the connecting layer 311 and the inner wall of the upper shell 1. When the upper shell 1 is pressed to be folded, a user cannot touch the joint between the upper shell 1 and the upper end of the connecting layer 311, the upper shell 1 is not easily disconnected from the connecting layer 311, and the stable connection between the upper shell 1 and the connecting layer 311 is guaranteed.

In this embodiment, the top surface of the upper casing 1 is provided with an upper opening 6, and a pot lid 14 is arranged at the upper opening 6. The width of the upper opening 6 is smaller than the width of the upper case 1. Connecting layer 311 is located the inner bag 3 top, and epitheca 1 cover is in connecting layer 311 upper end for connecting layer 311 upper end is wrapped in epitheca 1, and inner bag 3 upper end is wrapped in epitheca 1 promptly, and epitheca 1 roof is located connecting layer 311 top, makes inner bag 3 top also sheltered from by epitheca 1. Therefore, when the user presses the top of the upper shell 1 to fold, not only the joint of the connecting layer 311 and the upper shell 1 is not easily touched, but also the upper end of the inner container 3 is completely shielded by the upper shell 1 and is not easily pressed by the user, and the reliability of the connection of the connecting layer 311 and the upper shell 1 is further improved. In addition, the upper end of the inner container 3 is completely wrapped in the upper shell 1, so that the appearance experience of a user is promoted.

Specifically, the upper case 1 extends downward to the lower end of the connection layer 311, and when the connection layer 311 is mounted on the upper case 1, the connection layer 311 is completely received in the upper case 1. The upper shell 1 completely wraps the connecting layer 311 connected with the upper shell, so that the connecting layer 311 is not easily affected by external force, and the connection stability of the upper shell 1 and the connecting layer 311 is further improved.

Referring to fig. 4, in other embodiments, the lower end of the connection layer 311 protrudes from the lower end of the upper case 1, and the upper case 1 covers only the upper end of the connection layer 311 to reduce the amount of material used for the upper case 1.

Specifically, the lower end of connecting layer 311 has annular second protrusion 8, and the bottom surface at epitheca 1 is supported in the butt of the 8 upper ends of second protrusion to in the restriction connecting layer 311 lower extreme retraction epitheca 1, be favorable to guaranteeing that the length that connecting layer 311 stretched into epitheca 1 does not change, further guarantee connecting layer 311 upper end and epitheca 1 be connected stably.

The extension section 13 belongs to a part of the inner container 3, namely, the upper end of the inner container 3 protrudes out of the top surface of the upper shell 1 from the upper opening 6. The upper case 1 is mounted on the upper portion of the inner container 3, but does not cover the upper end of the inner container 3. When the longitudinal length of the inner container 3 is long, the inner container 3 may be bent and is not easy to store. The user can fold extension 13 in the epitheca 1 from last mouthful 6 earlier, then in folding the 3 lower extremes of inner bag into epitheca 1, divide twice and fold to reduce the 3 length of single folding inner bags, and then reduce folding degree of difficulty, and promote folding experience.

Specifically, the outer side wall of the extension section 13 is provided with a first protrusion 7, the first protrusion 7 is circumferentially distributed along the outer side wall of the extension section 13, when the upper end of the connecting layer 311 is connected in the upper shell 1, the lower end of the first protrusion 7 is abutted to the edge of the upper opening 6 to limit the lower end of the extension section 13 to be retracted into the upper shell 1, so that the connection between the upper end of the inner container 3 and the upper shell 1 is enhanced. Therefore, the upper case 1 is connected to the upper end of the connection layer 311 with a peel-off, and it is necessary to connect the upper case 1 to the extension section 13 with a peel-off. When the inner container 3 is in an unfolded state, the length of the extension section 13 protruding out of the upper shell 1 is not changed.

Referring to fig. 5, in this embodiment, the outer sidewall of the connection layer 311 is sleeved with a fixing ring 91, and the upper end of the connection layer 311 is compressed and sealed on the inner wall of the upper casing 1 by the fixing ring 91, so that the upper end of the connection layer 311 is fixed on the inner wall of the upper casing 1.

In other embodiments, the fixing ring 91 is integrally formed on the inner wall of the upper casing 1, and the fixing ring 91 does not need to be fixed to the upper casing 1.

In this embodiment, the inner container 3 includes two folded layers 31 and a bent portion 32 located between the two folded layers 31, and the folded layers 31 are connected by the bent portion 32. The connection layer 311 is a folding layer 31 for connecting the upper case 1, that is, the folding layer 31 located at the upper part of the inner container 3 is the connection layer 311. When the inner bag 3 is folded, the bent portion 32 is bent and the folded layers 31 are overlapped with each other, but the length of the single folded layer 31 before and after the folding is not changed. By using the single folding layer 31 as the connection layer 311, it is possible to prevent the connection layer 311 from being connected to the upper case 1 to affect the folding of the inner container 3.

In other embodiments, the inner container 3 does not include the bending portion 32, and the inner container 3 is made of a soft material. When the inner container 3 is pressed, the inner container 3 is integrally bent and deformed to achieve the purpose of folding.

Example two:

referring to fig. 1, a liquid heater comprises a foldable inner container 3, an upper shell 1 and a bottom shell 2.

The inner container 3 is cylindrical, the upper shell 1 is fixedly connected to the upper part of the inner container 3, and the bottom shell 2 is fixedly connected to the lower part of the inner container 3. The upper shell 1 is sleeved on the inner container 3, can be positioned at the top end of the inner container 3, and can also be positioned between the top end of the inner container 3 and the middle part of the inner container 3.
