Description

A kind of glass electric kettle

Technical field

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

Background technology

Electric kettle is exactly to the electric household appliance that can drink by drinkable water or beverage heating, the most of heating products in current market is as plastics, iron, aluminium, stainless steel etc., in use procedure, can there is multiple secondary chemical reaction, produce metal ion and harmful substance, health is had to certain influence.Glass electric kettle is nontoxic with it and be well received by consumers.

Traditional glass electric kettle is installed on heat-generating disc kettle body bottom opening place conventionally, small space just can reduce kettle body lock water-based energy, even cause and leak and cause danger, therefore very high to the dimensional requirement of glass pot body lower openings, the normal error that produces during because of blow-molded glass does not mate kettle body lower openings and heat-generating disc to cause very high percent defective, greatly improved production cost.As China Patent No. 201120228176.4 has proposed a kind of glass electric kettle, the bottom that mounting screw is arranged by being installed on glass pot body bottom, heat-generating disc is tightened on the installation step of kettle body, but because the area of heat-generating disc is greater than the opening of kettle body bottom, heat-generating disc can only be put into from the open top of kettle body, if the open top of kettle body is less than bottom opening, heat-generating disc cannot be put into kettle body.

Summary of the invention

The purpose of this utility model is for the deficiencies in the prior art, a kind of glass electric kettle is provided, even if the open top of kettle body is less than bottom opening, the vertical plane that heat-generating disc also can form by two breach enters kettle body inside, greatly reduce the dimensional requirement to kettle body top and bottom opening, reduce percent defective.

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

A kind of glass electric kettle, comprise bottomless glass pot body and heat-generating disc, kettle body bottom is provided with heat-generating disc installation step, heat-generating disc outer race has sealing ring and is placed on installation step, and the bottom that mounting screw arranges by being installed on glass pot body bottom, is tightened in heat-generating disc on installation step, base through screws is installed on bottom, there are two outside outstanding breach at kettle body bottom opening edge, and when heat-generating disc is vertically placed, the vertical plane that this heat-generating disc can form by two breach enters kettle body.

Described heat-generating disc is oval.

The major axis of described heat-generating disc is greater than two air line distances between breach, and the minor axis of heat-generating disc is less than two air line distances between breach.

The area of described heat-generating disc is as the criterion can cover kettle body bottom opening.

Described sealing ring upper surface has annular groove A and annular groove B.

One circle convex edge integrated with it arranged at described heat-generating disc bottom, and this convex edge is installed in annular groove A.

Described sealing ring lower surface has an annular groove C, and sealing ring lower surface inside edge has an annular groove D.

Bottom surface, interval between described groove C and groove D and the vertical range of sealing ring lower surface are less than 2mm.

Described installation step is installed in annular groove D.

Described sealing ring is silica gel sealing ring.

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

Even if 1. the open top of kettle body is less than bottom opening, also heat-generating disc can be put into kettle body, not high to kettle body dimensional requirement, the rate of can greatly reducing the number of rejects and seconds;

2. sealing ring is locked water-bound with secondary, and lock water-based can be good.

The specific embodiment

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

As Figure 1-5, the utility model glass electric kettle, comprise bottomless glass pot body 1 and heat-generating disc 2, kettle body 1 bottom is provided with heat-generating disc 2 installation steps 3, heat-generating disc 2 covers have sealing ring 4 and are placed on installation step 3, and the bottom 5 that mounting screw arranges by being installed on glass pot body 1 bottom, is tightened in heat-generating disc 2 on installation step 3, base 6 is installed on bottom 5 by screw, and there are two outside outstanding breach 8 at kettle body 1 bottom opening 7 edges.As shown in Figure 2, when heat-generating disc 2 is vertically placed, the vertical plane that this heat-generating disc 2 can form by two breach 8 enters kettle body 1.

Described heat-generating disc 2 is oval, and heat-generating disc 2 major axis are greater than two air line distances between breach 8, in the time that heat-generating disc 2 is installed on the installation step 3 of kettle body 1 inside, can cover two breach 8.The minor axis of heat-generating disc 2 is less than two air line distances between breach 8, guarantees that the vertical plane that heat-generating disc 2 can form by breach 8 while vertically placement enters kettle body 1.

The area of described heat-generating disc 2 is as the criterion can cover kettle body 1 bottom opening 7, guarantees sealing.

Described sealing ring 4 upper surfaces have annular groove A and annular groove B, one circle convex edge 9 integrated with it arranged at heat-generating disc 2 bottoms, this convex edge 9 is installed in annular groove A, when by mounting screw during to bottom 5 application of force, exert pressure by bottom 5, convex edge 9 is closely buckled in annular groove A, forms good hermetically-sealed construction.Described sealing ring 4 is silica gel sealing ring, sealing ring 4 is squeezed and is out of shape, now annular groove B inwall is close to heat-generating disc 2 bottoms, the air of annular groove B inside is extruded, be vacuum state, owing to being subject to the effect of atmospheric pressure, the inwall of annular groove B is tightly pressed in heat-generating disc 2 bottoms, form sucker, thereby reach the effect of secondary lock water.

Described sealing ring 4 lower surfaces have an annular groove C, sealing ring 4 inside edges have an annular groove D, 10 bottom surfaces, interval between groove C and groove D and the vertical range of sealing ring 4 lower surfaces are less than 2mm, installation step 3 is installed in annular groove D, in the time that installation step 3 occurs that because of blowing error causes, annular groove C, exert pressure by bottom 5, annular groove C inner air is extruded, be vacuum state, owing to being subject to the effect of atmospheric pressure, can form sucker, reach the effect of supplementing lock water, therefore the blowing of glass pot body 1 is required without too strict, even occur that slight error also can normally be used when blowing kettle body 1, the rate of can greatly reducing the number of rejects and seconds.Meanwhile, because breach 8 is outwards outstanding, the installation step 3 at breach 8 places can be installed in annular groove C, prevents from leaking.
