Description

A kind of vacuum heat insulation kettle structure

Technical field

The utility model relates to consumer goods industries, and in particular to a kind of vacuum heat insulation kettle structure.

Background technique

Electric kettle has been a kind of very universal small household appliances, with the raising of public energy conservation and environmental awareness, existing market On have many vacuum heat insulation kettles, but some are complicated for structure, and production technology is difficult.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides that a kind of structure is simple, and easy to produce, at low cost is true Empty heat-insulation water bottle structure.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

A kind of vacuum heat insulation kettle structure, including shell, liner, annular clamping ring, heating element, the heating element are set It sets in liner at the bottom, side outside the tank is arranged in the shell annular, and have between shell and liner and is spaced and is formed a wall, To close the top of wall, the annular clamping ring is arranged at wall bottom the upper end sealing welding of the shell and liner Portion, annular clamping ring close the bottom of wall with shell and liner sealing welding respectively, so as to form one close for wall The space closed and a sealing vacuum heat-preserving chamber can be formed by vacuumizing.

Preferably, the heating element is arranged outside the tank.

Preferably, the heating element is arranged inside liner.

Preferably, the weld of the annular clamping ring and shell is located at shell lower end inside.

Preferably, the weld of the annular clamping ring and liner is located at liner lower end outside.

Preferably, the weld of the annular clamping ring and liner is located at liner lower end bottom surface.

The beneficial effects of the utility model are:

As seen from the above technical solution, the utility model is equipped with a gap between shell and liner, passes through shell, liner And sealing welding and the air in the gap is pumped to form a sealing vacuum heat-preserving chamber, structure between annular clamping ring Simply, easy to produce and at low cost.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the overall structure figure of the utility model embodiment one；

Fig. 2 is partial enlarged view at A in Fig. 1；

Fig. 3 is the overall structure figure of the utility model embodiment two；

Fig. 4 is partial enlarged view at B in Fig. 3.

Specific embodiment

Referring to Fig.1, Fig. 2, Fig. 3 and Fig. 4, the following are the preferred embodiments of the utility model.

Embodiment one

As shown in Figure 1 and Figure 2, a kind of vacuum heat insulation kettle structure, including shell 1, liner 2, annular clamping ring 4, heating unit Part 5, the heating element 5 setting in 2 bottom of liner, the 1 annular setting of shell in 2 outside of liner, shell 1 and liner 2 it Between have and be spaced and form a wall, the upper end sealing welding of the shell 1 and liner 2 is to close the top of wall, institute The setting of annular clamping ring 4 is stated in wall bottom, annular clamping ring 4 respectively with shell 1 and 2 sealing welding of liner to close between The bottom of interlayer, so that wall forms a closed space and can form a sealing vacuum heat-preserving chamber 3 by vacuumizing, it is described Shell 1 and liner 2 are top opening structure, and fever is after the heating element 5 is powered with the water in heating inner liner 2.The letter of its structure It is single, it is easy to produce and at low cost.

Further, the heating element 5 is arranged outside liner 2, and certainly, the heating element 5 can also be arranged in Inside liner 2, it is not limited here.

Wherein, the weld of the annular clamping ring 4 and shell 1 is located at 1 lower end inside of shell, the annular clamping ring 4 It is located at 2 lower end outside of liner with the weld of liner 2.

Embodiment two

As shown in Figure 3, Figure 4, a kind of vacuum heat insulation kettle structure, including shell 1, liner 2, annular clamping ring 4, heating unit Part 5, the heating element 5 setting in 2 bottom of liner, the 1 annular setting of shell in 2 outside of liner, shell 1 and liner 2 it Between have and be spaced and form a wall, the upper end sealing welding of the shell 1 and liner 2 is to close the top of wall, institute The setting of annular clamping ring 4 is stated in wall bottom, annular clamping ring 4 respectively with shell 1 and 2 sealing welding of liner to close between The bottom of interlayer, so that wall forms a closed space and can form a sealing vacuum heat-preserving chamber 3 by vacuumizing, it is described Shell 1 and liner 2 are top opening structure, and fever is after the heating element 5 is powered with the water in heating inner liner 2.The letter of its structure It is single, it is easy to produce and at low cost.

Wherein, the weld of the annular clamping ring 4 and shell 1 is located at 1 lower end inside of shell, the annular clamping ring 4 It is located at 2 lower end bottom surface of liner with the weld of liner 2.

The preferred embodiment of the utility model is illustrated above, certainly, the utility model can also use Form different from the embodiment described above, those skilled in the art institute without departing from the spirit of the present invention The equivalent transformation or corresponding modification of work, all should belong in the protection scope of the utility model.
