Abstract

The utility model relates to an inner ring fire cover for a gas cooker, which comprises an annular cover base and a protective cover. The protective cover is disposed on top of the cover base, pluralities of fire holes are evenly arranged on an outer annular wall inside the cover base along a circumferential surface, a central penetrated hole of the cover base is formed at the center of an inner annular wall inside the cover base, the bottom of the protective cover is provided with an inserting column extending downwards and at least one supporting leg extending downwards, the inserting column is inserted into a slot disposed at the top of the cover base, and the supporting leg is supported on the top of the cover base. Compared with the prior art, the fire cover prevents the central penetrated hole from exposing, and effectively prevents dirt dropping inside the gas cooker and on the cover base. Simultaneously, the fire cover guarantees air ventilation space above the central penetrated hole, thereby ensuring supplementary effect of secondary air during combustion.

Description

A kind of inner ring fire lid that is used for gas-cooker

Technical field

The utility model belongs to the technical field of gas-cooker, relates in particular to a kind of inner ring fire lid that is used for gas-cooker.

Background technology

At present, operated by rotary motion has external ring fire cover and these two fire lids of inner ring fire lid in the burner of gas-cooker, and wherein, inner ring fire lid generally is cylinder, and the top of inner ring fire lid offers the fire hole of a plurality of circles along periphery.In order to improve the efficiency of combustion that is input to the combustion gas that the inner ring fire covers, make fuel gas buring more abundant, be provided with the central through hole isolated with fuel chamber in the many inner rings fire lid, the circulation by air in the central through hole reaches the needed Means of Secondary Air Supplement of fuel gas buring.But, in actual use, because inner ring fire lid is to be positioned at Centromedian position, the bottom of a pan, for common frying pan, inner ring fire lid is the most approaching with the distance in the bottom of a pan, causes the useful space of the fiery central through hole top of covering of inner ring very narrow and small, reduce the effect of Means of Secondary Air Supplement, sometimes, the bottom of a pan can too be pressed close to the central through hole of inner ring fire lid and almost block this central authorities' through hole, and central through hole is not had any effect.On the other hand, in the actual use, often have dirt to be dropped in the inner ring fire along the bottom of a pan and cover, perhaps directly drop to gas-cooker inside, pollute the gas-cooker internal structure, and the utmost point is not easy cleaning by this central authorities' through hole.

The utility model content

Technical problem to be solved in the utility model is that a kind of inner ring fire lid that is used for gas-cooker is provided at the present situation of prior art, and the supply effect of auxiliary air when it can guarantee to burn can prevent effectively that again dirt from polluting gas-cooker inside and inner ring fire lid.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used for the inner ring fire lid of gas-cooker, comprise and have external annulus and internal ring wall and overlook ringwise cage, external annulus offers a plurality of fire holes uniformly along periphery in the cage, the central authorities of internal ring wall just form the central through hole of cage in the cage, it is characterized in that: also comprise being arranged on the rounded protective cover of overlooking of cage top, wherein, this protective cover bottom surface is provided with an inserting column that stretches out and at least one leg that stretches out downwards downwards, this inserting column just is inserted among the jack of offering on the cage top, and this leg then is supported on the top of cage.

For making leg more reliable in the support at cage top, make protective cover be difficult for relative cage and rock, described protective cover bottom can be that center, left and right symmetrically are provided with two described legs with the diameter line at inserting column place.

Fire hole on the described cage can be for running through the circular port of cage external annulus, but for the flame that increases inner ring fire lid produces face, can offer two-layer fire hole up and down on the external annulus of described cage, the upper strata fire hole is a circular hole, lower floor's fire hole is the grooved hole, and, the bottom surface of external annulus is the inclined plane, so, the external annulus of cage bottom is shelved on the fuel chamber exit of burner, and the internal ring wall of cage then pine fits over the fuel chamber exit, in use, cage is difficult for stuck exit in fuel chamber, and the plug assembling is very simple, and the processing of fire hole also is convenient in the design in grooved hole.

Compared with prior art, advantage of the present utility model is: by the setting of protective cover on the cage, central through hole in the cage is hidden by protective cover, avoided the exposure of central through hole, can prevent effectively that dirt from dropping onto gas-cooker inside and cage part, simultaneously, because the support of leg on the protective cover, make between protective cover and the central through hole top and have certain spacing, guaranteed the circulation of air space of central through hole top, thus the supply effect of auxiliary air can guarantee to burn the time.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 4, the inner ring fire lid that this is used for gas-cooker comprises and overlooks ringwise cage 1 and be arranged on cage 1 top, overlook rounded protective cover 2;

Wherein, annular cage 1 has external annulus 11 and internal ring wall 12, make cage 1 bottom form the annular groove 13 that can communicate with fuel chamber, the central authorities of internal ring wall 12 just form the central through hole 14 of cage 1, external annulus 11 upper edge peripheries offer two-layer fire hole up and down uniformly, and upper strata fire hole 15 is a circular hole, and lower floor's fire hole 16 is the grooved hole, and the bottom surface 11a of external annulus 11 is the inclined plane;

Described protective cover 2 bottom surfaces are provided with an inserting column that stretches out 21 and two legs that stretch out 22 downwards downwards, these two legs 22 are center, left and right symmetrically setting with the diameter line of the protective cover 2 at inserting column 21 places, this inserting column 21 just is inserted among the jack of offering on cage 1 top 17, leg 22 then is supported on the top of cage 1, the spacing that the top of protective cover 2 and cage 1 is maintained fixed.
