Abstract

The utility model discloses an electric kettle. The electric kettle comprises a kettle body, a heating disc and a base. The heating disc is composed of a heating base and a heating protrusion corresponding to an opening in the bottom of the kettle body, wherein the heating protrusion is fixed to the center of the heating base, and the heating protrusion and the heating base are integrally formed. The kettle body is installed on the heating protrusion. A first sealing ring is arranged between the kettle body and the heating base. A fixing ring and a second sealing ring are sequentially installed on the heating protrusion from top to bottom. The fixing ring is of an inverted funnel shape, the edge of the lower surface of the fixing ring is provided with an annular fixing ring flange, the inner diameter of a lower opening of the inverted funnel shape corresponds to the outer diameter of the heating protrusion, and the inner diameter of an upper opening of the inverted funnel shape is smaller than the outer diameter of the heating protrusion. The outer side of the second sealing ring is provided with an annular sealing ring flange, and the annular sealing ring flange is clamped between the kettle body and the fixing ring. According to the electric kettle, the heating disc and the kettle body are fixed through the fixing ring and screws or glue is not needed, so that the electric kettle is safe, healthy and stable in structure, a better anti-leakage effect is achieved, the cushioning effect is also achieved, and the kettle body is better protected.

Description

A kind of electric kettle

Technical field

The utility model relates to kettle tool, relates in particular to a kind of electric kettle.

Background technology

Electric kettle is that drinkable water or beverage heating are arrived to drinkable device, occupies very important status on market.The heat-generating disc of tradition electric kettle is fixed heat-generating disc and kettle body with screw or glue conventionally.The mode being screwed as made, screw use for a long time can be got rusty or get loose, and easily causes kettle body structure unstable; As use the hydropexic mode of glue, in the time that electric kettle heats liquid, temperature is higher, easily makes glue decomposite harmful substance, affects health.

Summary of the invention

The purpose of this utility model is to provide a kind of electric kettle, to solve the problem and the defect that exist in above-mentioned technology.

For achieving the above object, the utility model by the following technical solutions:

A kind of electric kettle, comprise that bottom is provided with kettle body, heat-generating disc and the base of opening, heat-generating disc is made up of with the heating projection corresponding with kettle body bottom opening the seat that generates heat, heating projection be fixed on heating seat in the heart and one-body molded with it, kettle body is installed on heating projection by bottom opening, between kettle body and heating seat, be provided with the first sealing ring, heating projection is also provided with can be locked heating protruding retainer plate and the second sealing ring from top to bottom successively.

Further, retainer plate is down infundibulate, this fall funnel shaped lower surface edge have one with it integrated annular retainer plate flange, the funnel shaped end opening internal diameter that falls is corresponding with the protruding external diameter of heating, internal diameter suitable for reading is less than the protruding external diameter of heating.

Preferably, there is an O-ring seal flange integrated with it in the second sealing ring outside, and sealing circle flange is stuck between kettle body and retainer plate.

Retainer plate is stainless steel products, and the first sealing ring and the second sealing ring are silica gel sealing ring.

Compared with prior art, the utlity model has following beneficial effect:

1. fix heat-generating disc and kettle body by retainer plate, avoid using screw or glue, safety and Health;

2. retainer plate can inwardly be tight against heat-generating disc, and Stability Analysis of Structures is difficult for getting loose;

3. the structure of the first sealing ring can reach better lock water effect, and the second sealing ring also can play cushioning effect when strengthening lock water-based energy, can protect better kettle body.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Fig. 1-8; the utility model electric kettle; comprise that bottom is provided with kettle body 1, heat-generating disc 2 and the base of opening; heat-generating disc 2 is made up of with the heating projection 7 corresponding with kettle body 1 bottom opening heating seat 6; heating projection 7 be fixed on heating seat 6 in the heart and one-body molded with it, kettle body 1 is installed on heating projection 7 by bottom opening, between kettle body 1 and heating 6, is provided with the first sealing ring 3; when strengthening lock water-based energy, also can play cushioning effect, protection kettle body is not easily broken.Heating projection 7 is also provided with retainer plate 5 and second sealing ring 4 of the heating projection 7 that can be locked from top to bottom successively.The heating projection 7 of retainer plate 5 being inserted in to heat-generating disc 2, down compresses by pressure, to fix kettle body 1 and heat-generating disc 2, avoids using screw or glue, safety and Health.

Retainer plate 5 is down infundibulate, this fall funnel shaped lower surface edge have one with it integrated annular retainer plate flange 8, the funnel shaped end opening internal diameter that falls is corresponding with the external diameter of heating projection 7, retainer plate 5 is locked on to heating projection 7 with pressure, because internal diameter suitable for reading is slightly less than the external diameter of heating projection 7, when being pressed into, retainer plate 5 can produce elastic deformation, can produce larger frictional force with the sidewall of heating projection 7, thereby retainer plate 5 can inwardly be tight against heat-generating disc 2, after being pressed into, be difficult to become flexible, make kettle body 1 more stable with the structure of heat-generating disc 2, be difficult for getting loose.

There is an O-ring seal flange 9 integrated with it in the second sealing ring 4 outsides, the second sealing ring 4 is stuck between kettle body 1 and heating projection 7, retainer plate 5 and heating projection 7, sealing ring flange 9 is stuck between kettle body 1 and retainer plate 5, retainer plate 5 is inserted in protruding 7 o'clock of heating, retainer plate flange 8 is pushed down sealing ring flange 9, the second sealing ring 4 is set and can effectively prevents from occurring space between kettle body 1 and retainer plate 5, heat-generating disc 2, strengthen better lock water-based energy.

Described retainer plate 5 is stainless steel products, prevents from getting rusty.

Described the first sealing ring 3 and the second sealing ring 4 are silica gel sealing ring, and lock water is effective.
