[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0024] First, please refer to Figure 1 , Figure 2 as well as Figure 3 The utility model provides a burner head, comprising a burner head body 1, an air intake pipeline 2 and an air mixing pipe 3. The air outlet end of the air intake pipeline 2 is connected to the burner head body 1, the air intake channel 21 in the air intake pipeline 2 is communicated with the air path 11 in the burner head body 1, the side wall of the air intake end of the air intake pipeline 2 is provided with an air intake port 22, the air outlet end of the air mixing pipe 3 is connected to the air intake end of the air intake pipeline 2, the air mixing chamber 31 in the air mixing pipe 3 is communicated with the air intake channel 21, and the side wall of the air mixing pipe 3 is provided with a plurality of air intake holes 32, and the plurality of air intake holes 32 are communicated with the air mixing chamber 31.

[0025] In a specific application, the air inlet end of the mixing pipe 3 is connected to the air outlet end of the gas valve 4, and a fire cover 8 is provided on the burner body 1. The fire cover 8 has an air passage 81 connected to the air path 11, and the top side wall of the fire cover 8 has a plurality of fire outlets 82. The plurality of fire outlets 82 are evenly arranged and connected to the air path 81. The gas enters the gas valve 4 through the air inlet pipe 43 of the gas valve 4, and then enters the gas path 11 through the mixing chamber 31 and the air inlet channel 21 in turn, and flows out from the plurality of fire outlets 82. When the gas flows through the mixing chamber 31 and the air inlet channel 21, the outside air enters the air path 11, the air inlet channel 21 and the mixing chamber 31 through the air inlet hole 32 and the air inlet 22, so that the gas after the gas and air are fully mixed flows out from the plurality of fire outlets 82 and is ignited to form a flame.

[0026] In some preferred embodiments, the air inlet end of the mixing pipe 3 is used to connect with the first air outlet pipe 41 of the gas valve 4, and the inner diameter of the first air outlet pipe 41 is the same as the inner diameter of the mixing pipe 3. In specific applications, by designing the inner diameter of the first air outlet pipe 41 to be the same as the inner diameter of the mixing pipe 3, the flow rate of the gas flowing out of the first air outlet pipe 41 after entering the mixing pipe 3 can be kept unchanged, so as to avoid the flow rate change from affecting the amount of air entering the intake channel 21 from the intake port 22.

[0027] In some preferred embodiments, the air inlet pipeline 2 includes a first diameter-reducing section and a second diameter-reducing section, the inner diameter of the first diameter-reducing section gradually decreases from the air inlet end to the air outlet end, and the inner diameter of the second diameter-reducing section gradually increases from the air inlet end to the air outlet end. In specific applications, by designing the inner diameter of the first diameter-reducing section to gradually decrease from the air inlet end to the air outlet end and designing the inner diameter of the second diameter-reducing section to gradually increase from the air inlet end to the air outlet end, the gas and air can be fully mixed in the first diameter-reducing section, and then transported to various places in the gas path 11 under the action of the second diameter-reducing section.

[0028] In some preferred embodiments, the maximum inner diameter of the first diameter-changing section is smaller than the maximum inner diameter of the second diameter-changing section. By designing the maximum inner diameter of the first diameter-changing section to be smaller than the maximum inner diameter of the second diameter-changing section, the mixed gas and air can be uniformly transported to various locations in the gas path 11. It should be noted that the maximum inner diameter of the first diameter-changing section is smaller than the maximum inner diameter of the second diameter-changing section, which means that the projection area of ​​the maximum inner diameter of the first diameter-changing section along its length direction is smaller than the projection area of ​​the maximum inner diameter of the second diameter-changing section along its length direction.

[0029] In some preferred embodiments, the burner further includes a nozzle 5. A mounting plate 6 is mounted at the bottom of the burner body 1, and the nozzle 5 is disposed on the mounting plate 6. The air inlet end of the nozzle 5 is connected to the second air outlet pipe 42 of the gas valve 4 through the air guide pipe 7. In specific applications, by adding the nozzle 5, the nozzle 5 cooperates with the burner body 1 to increase the power of the burner, thereby shortening the cooking time.

[0030] In some preferred embodiments, the inner diameter of the air duct 7 is smaller than the inner diameter of the second air outlet pipe 42. In practical applications, by designing the inner diameter of the air duct 7 to be smaller than the inner diameter of the second air outlet pipe 42, the flow rate of the gas entering the air duct 7 through the second air outlet pipe 42 can be increased and the pressure can be reduced, so that more external air can enter the nozzle 5 through the through holes on the side wall of the nozzle 5 under the action of atmospheric pressure and be fully mixed with the gas to ensure full combustion of the gas.

[0031] In some preferred embodiments, the burner body 1 is a hollow annular structure, and the nozzle 5 is located in the center of the burner body 1. By arranging the nozzle 5 in the center of the burner body 1 of the annular structure, the flame sprayed by the nozzle 5 acts on the center of the bottom of the pot body, so that the pot body is heated evenly.

[0032] In some preferred embodiments, the bottom of the burner body 1 is provided with a plurality of mounting posts 12, and the bottom of each mounting post 12 is provided with a mounting hole 121. In specific applications, by providing the mounting holes 121 at the bottom of the mounting posts 12, it is convenient to use bolts to install and fix the burner body 1 at a predetermined position of the cooker. Specifically, in this embodiment, the number of mounting posts 12 is three, and the three mounting posts 12 are evenly distributed at the bottom of the burner body 1 to ensure that the burner body 1 is firmly and stably installed.

[0033] In some preferred embodiments, the burner body 1 and the air intake pipe 2 are integrally formed. In specific applications, by designing the burner body 1 and the air intake pipe 2 as an integral part, compared with the separate design of the burner body 1 and the air intake pipe 2, not only the time required for connection is saved, but also the sealing of the connection between the burner body 1 and the air intake pipe 2 can be ensured to be good.

[0034] In a second aspect, the utility model provides a stove, comprising the burner of the first aspect.

[0035] To sum up, in one or more embodiments of the present invention, the burner head and the stove of the present invention are provided with a mixing pipe 3 with a plurality of air inlet holes 32 on the side wall at the air inlet end of the air inlet pipeline 2, so that when gas is supplied to the burner head, the outside air can enter the air flow passage composed of the gas path 11, the air inlet channel 21 and the mixing chamber 31 through the air inlet port 22 and the air inlet holes 32, so that the amount of air in the air flow passage is increased, so that the gas in the air flow passage can be fully mixed with the air to achieve full combustion, thereby avoiding gas waste.
