Further, described heating ring lower end is connected with the first elastic component that extends along vertical direction.

Further, described the first elastic component is spring.

Further, be provided with a plurality of described cracks that distribute alternately in described heating ring sidewall, a plurality of described cracks are separated into a plurality of arc pieces with described heating ring, are connected with outside each described arc piece along horizontally extending the second elastic component in the described arc piece outside.

Further, described the second elastic component is spring.

Further, described crack extends along the vertical direction of described heating ring sidewall.

The utility model also provides heater, comprises above-mentioned heating component.

Compared with prior art, the heating ring of heating component of the present utility model and container are in the process of expanding with heat and contract with cold, be provided with crack in heating ring, be non-sealing ring body, the space of its flexible distortion, thus can keep contacting with vessel faces always, improve the efficiency of heating surface, avoid appearance point contact, be convenient to separating and assembly manipulation between heating ring and container.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

The utility model provides heating component, and the heating ring that comprises container and be sheathed on described container lower end outer surface is provided with crack in the sidewall of described heating ring, and described crack runs through the interior outside and the upper and lower side of described heating ring sidewall.

In the utility model, owing to being provided with crack in heating ring, it has the strain space, avoid in the process of expanding with heat and contract with cold, between heating ring and container, appearance point contacts cooperation, thereby, greatly improve the efficiency of heating surface of this heating component, and be convenient to separating and assembly manipulation between heating ring and container.

Below in conjunction with concrete accompanying drawing, realization of the present utility model is described in detail.

As shown in Fig. 1 ~ 3, the preferred embodiment that provides for the utility model.

The heater that the present embodiment provides comprises heating furnace of family expenses etc., and it includes heating component 1, shell and other parts etc.

Above-mentioned heating component 1 comprises container 11 and heating ring 12, has cavity volume in container 11, can be used for placing the object that needs heating, such as food and water etc.; Heating ring 12 is enclosed within on container 11 lower end outer surfaces, and it can realize heating efficiency by connecing electricity, and transfers heat to container 11, thereby realizes the effect of the object in heating container 11.

In the present embodiment, above-mentioned heating ring 12 sidewalls are provided with crack 17, and this crack 17 runs through the interior outside and the upper and lower side of heating ring 12 sidewalls, make heating ring 12 form discontinuous ring body, and simultaneously, this crack 17 also provides the space for the strain of heating ring 12.

Like this, above-mentioned container 11 and heating ring 12 are in the process of expanding with heat and contract with cold, expansion or contraction along with container 11 or heating ring 12, crack 17 on heating ring 12 sidewalls can satisfy the strain space of permission, make the heating ring 12 can bulk deformation, avoid occurring local deformation, thus also guaranteed heating ring 12 inner surfaces all the time with container 11 appearance plane-plane contacts, the efficiency of heating surface is high, also is convenient to separating or assembly manipulation between heating ring 12 and container 11.
