Description

Technical Field

[0001] The present invention relates to stove technology, and more particularly, to a burner. Background Art

[0002] Traditional burners generally use inner and outer double-ring flames to heat the cookware placed thereon to improve the heating efficiency and shorten the cooking time. Most current burners include a base, a burner head, an outer flame cover and an inner flame cover installed on the burner head, and outer fire holes and inner fire holes are respectively formed on the peripheral walls of the outer flame cover and the inner flame cover.

[0003] However, the flames generated by the current outer fire holes and inner fire holes are relatively uniform, and the flames mainly rise upward. In order to heat the boiler, people usually install a skeleton on the stove top to support the boiler. During the support process, the flames will also burn the skeleton, resulting in the generation of CO and a large amount of flue gas when the skeleton is burned. This will not only affect the physical health of the people cooking, but also cause environmental pollution.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a burner that can avoid burning the stove top skeleton and avoid generating waste gases such as CO.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: A burner includes a base, a burner head detachably connected to the base, and an outer flame cover and an inner flame cover detachably connected to the top surface of the burner head. A plurality of groups of outer fire holes communicating with the inside are formed on the outer peripheral wall of the outer flame cover, and a fire avoidance space is formed between adjacent groups of the outer fire holes for accommodating the stove top skeleton.

[0007] By adopting the above technical solutions, by providing the fire avoidance space, it can avoid the skeleton supporting the boiler on the stove top from being continuously burned by the flames during the use of the burner, and thus the skeleton will not generate waste gases such as CO due to the burning of the flames, thereby avoiding the situation of CO or other waste gas poisoning when people use the burner, ensuring people's life safety and also ensuring the cleanliness of the environment.

[0008] The present invention is further provided that the number of each group of the outer fire holes is at least 1, and the width of the fire avoidance space is greater than the distance between adjacent outer fire holes.

[0009] The present invention is further configured as follows: A ring of flame-stabilizing grooves that are inclined downward and recessed are provided on the outer peripheral wall of the outer ring burner cap. A plurality of groups of through holes communicating with the inside of the outer ring burner cap are provided in the flame-stabilizing grooves. The number of groups of the through holes is the same as the number of groups of the outer fire holes, and the distance between adjacent groups of the through holes is equal to the distance of the fire avoidance space.

[0010] The present invention is further configured as follows: The number of each group of the through holes is at least one, and the through holes and the outer fire holes are arranged in a staggered manner.

[0011] By adopting the above technical solution, since the through holes and the outer fire holes are arranged in a staggered manner, when the gas leaving the through holes burns, it can also ignite the gas escaping between the outlets of two adjacent outer fire holes, thereby ensuring the intensity of the flame and preventing the waste of gas.

[0012] The present invention is further configured as follows: The through holes are inclined downward starting from one side of the flame-stabilizing groove.

[0013] By adopting the above technical solution, since the through holes are inclined downward starting from one side of the flame-stabilizing groove, the through holes can preliminarily guide the gas, so that the gas leaving the inside of the outer burner cap can move upward.

[0014] The present invention is further configured as follows: The outlets of the through holes are provided on the bottom surface, top surface and inner peripheral wall of the flame-stabilizing groove.

[0015] By adopting the above technical solution, since the outlets of the through holes are provided on the bottom surface, top surface and inner peripheral wall of the flame-stabilizing groove, the outlet area of the through holes is larger than the opening area per unit area in the flame-stabilizing groove. Thus, the amount of gas leaving the through holes is greater than the amount of gas in the flame-stabilizing groove per unit area. This enables the gas to be fully guided by the flame-stabilizing groove and ensures that the gas concentration leaving the flame-stabilizing groove is relatively high, enabling the gas to burn fully.

[0016] The present invention is further configured as follows: A connecting member is fixedly connected between the inner ring and the outer ring of the flame divider. A plurality of embedding grooves are provided on the connecting member. A plurality of positioning columns are integrally formed on the base, and the positioning columns are embedded in the embedding grooves.

[0017] By adopting the above technical solution, by providing the embedding grooves and the positioning columns, when the flame divider needs to be connected to the base, the positioning columns can play an effective positioning role, simplifying the assembly of the flame divider and the base by people and improving work efficiency.

[0018] In summary, the present invention has the following beneficial effects:

[0019] By setting up a fire - avoiding space, it can prevent the framework supporting the boiler on the stove top from being continuously burned by the flame during the use of the burner. Thus, it can also prevent the framework from generating waste gases such as CO due to the burning of the flame, thereby avoiding the situation of people being poisoned by CO or other waste gases during the use of the burner, ensuring people's life safety and the cleanliness of the environment.

[0024] The present invention will be described in detail below with reference to the drawings and embodiments.

[0025] Embodiment:

[0026] As Figure 1 shown, a burner includes a base 1, a flame divider 2 detachably connected to the base 1, an outer ring fire cap 4 and an inner ring fire cap 5 detachably connected to the top surface of the flame divider 2. A sheet - shaped connecting piece 3 is integrally formed between the inner and outer circles of the flame divider 2. A plurality of embedding grooves are formed on the connecting piece 3, and a plurality of positioning posts 11 are integrally formed on the base 1. The positioning posts 11 are embedded in the embedding grooves.

[0027] As Figure 2 shown, a plurality of groups of outer fire holes 41 communicating with the inside are formed on the outer peripheral wall of the outer ring fire cap 4. A fire - avoiding space 42 is formed between adjacent groups of outer fire holes 41. The fire - avoiding space 42 is used to accommodate the stove framework. The number of each group of outer fire holes 41 is at least 1, and the width of the fire - avoiding space 42 is greater than the distance between adjacent outer fire holes 41.

[0028] As Figure 3As shown, a circle of flame stabilizing grooves 6 that are inclined downward and recessed are formed on the outer peripheral wall of the outer ring burner cap 4. A plurality of groups of through holes 61 communicating with the inside of the outer ring burner cap 4 are formed in the flame stabilizing grooves 6. The number of groups of the through holes 61 is the same as the number of groups of the outer fire holes 41, and the distance between adjacent groups of through holes 61 is equal to the distance of the fire avoiding spaces 42. The number of each group of through holes 61 is at least one, and the through holes 61 and the outer fire holes 41 are arranged in a staggered manner. Moreover, the through holes 61 are inclined downward starting from one side of the flame stabilizing grooves 6, and the outlets of the through holes 61 are formed on the bottom surface, top surface and inner peripheral wall of the flame stabilizing grooves 6.

[0029] By providing the fire avoiding spaces 42, when the burner is installed on the stove, when people install the supporting framework on the stove, the supporting frameworks are respectively located at the positions where the fire avoiding spaces 42 are located. Thus, when the outer fire holes 41 and the inner fire holes of the burner burn gas, the flame will not burn the framework of the stove, avoiding the generation of CO when the framework is burned by the flame, and reducing the generation of a large amount of flue gas during the combustion of the burner, thereby ensuring that people can reduce the harm to the human body when using the burner and ensuring environmental cleanliness.

[0030] Moreover, due to the arrangement of the through holes 61, gaps identical to the fire avoiding spaces 42 are also formed, so that the flame formed below the outer fire holes 41 can also avoid the framework and prevent the framework from being burned by the flame. The gas guided away through the through holes 61 will maintain an upward combustion state due to the guiding effect of the flame stabilizing grooves 6 and the through holes 61, avoiding the outward diffusion of the flame. Thus, the flame can mainly fully ignite the gas leaving the outer fire holes 41, avoiding the escape of waste gases such as CO due to insufficient combustion of the inner flame of the gas leaving the outer fire holes 41, thereby ensuring people's life and health and also ensuring environmental cleanliness.

[0031] Secondly, since the outlet area of the through holes 61 is larger than the opening area of the flame stabilizing grooves 6 per unit area, after the gas leaves the through holes 61, it can be guided by the flame stabilizing grooves 6, and then the gas leaving the flame stabilizing grooves 6 remains in a relatively concentrated state, avoiding the situation of gas dispersion and enabling the gas to be fully burned.

[0032] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
