Description

Fire lid, combustor and cooking utensils with buffering Technical Field The utility model relates to the technical field of stoves, in particular to a fire cover with a buffer, a combustor and a stove. Background The performance of the kitchen range product sold in the market at present is simulated and tested in a laboratory environment in the development process, and the combustion working condition meets the national standard basic requirement. However, in practical application, various combustion working conditions can occur due to poor design applicability of the gas stove, and in addition, the combustion working conditions can occur due to large difference of gas sources in various places nationwide, so that the user experience is poor. Accordingly, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art. Disclosure of utility model The utility model aims to provide a fire cover with a buffer, which can improve combustion stability and combustion performance of products. Another object of the present utility model is to provide a burner, which includes the fire cover with buffer, and can improve combustion stability and combustion performance of products. The utility model also aims to provide a kitchen range, which comprises the burner, and can improve combustion stability and combustion performance of products. In order to achieve the above object, the present utility model provides the following technical solutions: The flame cover with the buffer comprises an annular body, wherein an annular flame stabilizing groove is formed in the periphery of the body, a main flame hole and a flame stabilizing hole are formed in the side wall of the body, the main flame hole penetrates through the side wall of the body, the top of the flame stabilizing hole is located inside the side wall of the body, the flame stabilizing hole is communicated with the flame stabilizing groove, and the top of the flame stabilizing hole is higher than the top surface of the flame stabilizing groove. According to one embodiment of the utility model, the main fire hole communicates with the flame holding tank. According to one embodiment of the utility model, a first included angle is formed between the axial direction and the horizontal direction of the main fire hole, and a second included angle is formed between the axial direction and the horizontal direction of the flame stabilizing hole. According to one embodiment of the utility model, the degrees of the first and second included angles are both 30-45 degrees. According to one embodiment of the utility model, the first included angle has a degree of 38 degrees. According to one embodiment of the utility model, the top of the body is provided with a cover plate, which closes the top of the body. According to one embodiment of the utility model, the width of the flame holding groove is 0.6-1.2mm. According to one embodiment of the utility model, the communication area between the flame holding groove and the main fire hole is one fourth of the cross-sectional area of the main fire hole. The utility model also provides a combustor, which comprises the fire cover with the buffer. The utility model also provides a kitchen range comprising the burner. Compared with the prior art, the embodiment of the utility model has the advantages that: The flame cover is provided with the flame stabilizing hole and the flame stabilizing groove which are communicated with each other, so that the gas pressure can be released, the flow speed of the gas flow out of the main flame hole is reduced, the top of the flame stabilizing hole is higher than the top surface of the flame stabilizing groove, and when the gas passes through the flame stabilizing hole, the cavity of the flame stabilizing hole is filled with the gas to form a buffering vortex, so that the energy of the gas flow is lost, the gas flow speed is reduced, the combustion stability is improved, and the combustion performance of a product is improved.
