Detailed Description

The present invention is further illustrated by way of the following examples, which are not intended to limit the scope of the invention.

As shown in fig. 1-4, the present embodiment discloses a fire cover of a kitchen range, which includes a fire cover body 1, wherein the fire cover body 1 includes an annular outer side wall 101, the outer side wall 101 has a plurality of main fire holes 104, the outer side wall 101 has a plurality of air guide blind holes 105, a plurality of annular cutting grooves 106 have been opened on the outer side surface of the outer side wall 101, and the plurality of annular cutting grooves 106 are all recessed inwards and are communicated with the plurality of main fire holes 104 and the plurality of air guide blind holes 105.

The outer side wall 101 is circular, and the main fire hole 104 extends from the bottom surface of the outer side wall 101 and the bottom of the inner side surface to the top end of the outer side surface of the outer side wall 101 in an inclined upward manner, so that the inner space and the outer space of the outer side wall 101 are communicated through the main fire hole 104. The air guide blind hole 105 extends obliquely upward from the bottom surface of the outer side wall 101 in a direction away from the center of the outer side wall 101 without communicating with the outer side surface of the outer side wall 101. Two annular cutting grooves 106 are opened on the outer side surface of the outer side wall 101, the annular cutting grooves 106 extend from the outer side surface of the outer side wall 101 to the direction of the circle center of the outer side wall 101, and the two annular cutting grooves 106 are both communicated with the main fire hole 104 and the air guide blind hole 105. Therefore, a part of the fuel gas in the main fire hole 104 flows out of the annular cutting groove 106, continues to diffuse and flow to the outside of the annular cutting groove 106 in the annular cutting groove 106, a part of the fuel gas continues to flow out along the main fire hole 104, and after the fuel gas in the main fire hole 104 flows through the annular cutting groove 106 for more than two times, the diffusion speed of the fuel gas is rapidly reduced. Similarly, after the gas in the blind gas guiding hole 105 flows through the annular cutting groove 106 more than twice, the diffusion speed of the gas is rapidly reduced

The plurality of annular cutting grooves 106 communicated with the main fire hole 104 and the air guide blind hole 105 are formed in the outer side face of the outer side wall 101, so that when gas in the main fire hole 104 flows through the annular cutting grooves 106 each time, the diffusion speed of the gas is rapidly reduced, the purpose of enabling the gas to stably flow out is achieved, flames among the plurality of annular cutting grooves 106 can mutually stabilize, and a high flame stabilizing effect is achieved.

A plurality of annular slots 106 are respectively distributed on the outer side wall 101 of the fire cover body 1 at intervals up and down.

The minimum distance between the two annular cut grooves 106 is greater than 2 times the groove width of the annular cut grooves 106.

Two annular slots 106 are distributed up and down on outer sidewall 101. The cross-sectional shape of the annular cutout groove 106 is rectangular. The vertical distance between the two annular undercut grooves 106 is greater than 2 times the groove width. By setting the minimum distance between the two annular cutting grooves 106 to be 2 times larger than the groove width of the annular cutting grooves 106, the effect of mutual flame stabilization of flames between the two annular cutting grooves 106 is improved, and a better flame stabilization effect is achieved.

The fire lid body 1 further comprises an annular inner side wall 102 and a top surface 103, the top surface 103 is annular, an outer ring of the top surface 103 is fixedly connected to the outer side wall 101, and an inner ring of the top surface 103 is fixedly connected to the inner side wall 102.

The fire lid body 1 further includes an inner sidewall 102 and a top surface 103. The inner side wall 102 is annular. The inner circle of top surface 103 is connected to the top end of inner sidewall 102 and the outer circle of top surface 103 is connected to the top end of outer sidewall 101. The top surface 103 is inclined downwards from the joint of the outer ring and the outer side wall 101 to the direction of the circle center of the outer side wall 101, and the joint of the inner ring and the inner side wall 102 of the top surface 103 is lower than the height of the joint of the top surface 103 and the outer side wall 101. And the top surface 103 itself is slightly convex upward in an arc shape to ensure that liquid can run down the top surface 103 without remaining on the top surface 103.

The outer side wall 101, the inner side wall 102 and the top surface 103 surround and form an air mixing cavity 107, the main fire hole 104 is obliquely arranged upwards from the air mixing cavity 107, and the main fire hole 104 is communicated with the air mixing cavity 107, the outer side surface of the outer side wall 101 and the annular cutting groove 106.

The outer side wall 101, the inner side wall 102 and the top surface 103 are enclosed from three directions to form a gas mixing cavity 107, and after gas injected from the gas pipeline enters the gas mixing cavity 107, the gas diffuses out of the fire cover body 1 through the main fire holes 104, the air guide blind holes 105 and the annular cutting groove 106.

An air guide blind hole 105 is provided obliquely upward from the bottom surface of the outer side wall 101, and the air guide blind hole 105 communicates with the air mixing chamber 107 and the annular cut groove 106.

The air guide blind hole 105 is obliquely arranged upwards from the air mixing cavity 107, so that sundries are prevented from falling into the air guide blind hole 105 to cause the air guide blind hole 105 to be blocked or unsmooth air outlet, and the stability of gas diffusion of the fire cover of the stove is ensured.

The top surface 103 slopes downwardly from the outer race to the inner race.

By providing the top surface 103 with a center-down slope, liquid overflowing from the pot can flow down the top surface 103, the sloped top surface design being such that liquid does not remain on the fire lid body.

The plurality of main fire holes 104 and the plurality of air guide blind holes 105 are arranged in a staggered and spaced mode.

On the outer side wall 101 along the circumferential direction of the fire cover body 1, the main fire holes 104 and the air guide blind holes 105 are alternately arranged at intervals. The main fire holes 104 and the air guide blind holes 105 are arranged at staggered intervals, so that the fuel gas in the annular cutting groove 106 can be stably diffused, and the stability of the fuel gas diffusion is improved.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
