Description

Technical Field

[0001] The utility model relates to the technical field of clay pot stoves, in particular to a burner head for an electric spray clay pot stove. Background Art

[0002] The clay pot stove is a new type of kitchen appliance, which is available in gas and electric types. The gas-type clay pot stove can use vegetable oil as fuel, which is more energy-saving and environmentally friendly. However, the burner head that is currently matched with the clay pot stove is easily damaged, and the nozzle in the burner head is exposed to high temperature environment for a long time, and the long-term use quality cannot be guaranteed. Frequent replacement of burner head accessories will increase the cost of use.

[0003] Chinese patent CN202321882462.1 discloses a side needle burner, which can avoid the problem of oil leakage at the bottom of the ignition needle, but the nozzle is in a high temperature environment for a long time, the heat dissipation is slow, and the service life is reduced.

[0004] Therefore, how to provide a burner head for an electric spray cooker with a simple structure and a long service life is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In view of this, the utility model provides a burner head for an electric spray pot stove, which has a simple structure, a nozzle that is not easily damaged and a long service life.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a burner head for an electric spray pot stove, comprising a shell, a fire bowl, a nozzle and an ignition needle, the fire bowl being installed inside the shell, the ignition needle being installed on the shell and the needle head of the ignition needle extending into the fire bowl, the nozzle being detachably connected to the bottom of the shell, an air inlet being provided on one side wall of the shell, an air outlet being provided on the other side wall, the air inlet being connected to an air inlet bend pipe, an air guide cover being fixedly connected to the inner bottom of the shell, an air duct being formed between the air guide cover and the inner bottom wall of the shell, one end of the air duct being connected to the air inlet, and the other end being connected to the air outlet, a vent being provided on the air guide cover, a heat-resistant bowl being detachably connected to the bottom of the fire bowl, a through hole for avoiding the nozzle being provided in the middle of the heat-resistant bowl, and the nozzle passing through the air duct, the vent and the through hole enters the fire bowl.

[0007] The beneficial effects of the utility model are as follows: an air duct is formed between the air guide cover and the shell, the nozzle is located in the air duct, the heat of the nozzle is taken away by the airflow, the temperature of the nozzle can be reduced, and the nozzle is prevented from being at high temperature for a long time; the heat-resistant bowl can effectively isolate the heat transfer from the fire bowl to the nozzle, avoid premature damage to the nozzle, and extend its service life.

[0008] Preferably, the air guide cover is a U-shaped groove plate structure, and there is a spacing distance between the air guide cover and the heat-resistant bowl.

[0009] The resulting technical effect is: the deflector cover can realize air diversion, and there is a distance between the deflector cover and the heat-resistant bowl, so that part of the air in the through-air duct can smoothly enter the fire bowl through the vents, realizing the combustion of the fuel. Due to the high temperature of the fire bowl, the air will inevitably be heated when entering the fire bowl, which will not affect the combustion efficiency of the fuel.

[0010] Preferably, the air outlet flow rate of the air outlet is smaller than the air inlet flow rate of the air inlet, and the air outlet and the air inlet are both located at the bottom edge of the side wall of the shell.

[0011] The resulting technical effect is: the purpose of the small diameter of the air outlet is to ensure that most of the air enters the fire bowl to complete the oxygen supply required for fuel combustion. The opening of the air outlet can also realize air flow, take away the heat of the nozzle, and avoid the nozzle temperature being too high.

[0012] Preferably, the heat-resistant bowl is a stainless steel bowl.

[0013] The resulting technical effect is: the stainless steel bowl can effectively reduce the heat transfer from the fire bowl to the nozzle, dissipate heat quickly, stainless steel has low thermal conductivity, is resistant to high temperatures, has sufficient strength and thermal strength at high temperatures, and is anti-oxidation and corrosion-resistant.

[0014] Preferably, the ignition needle is arranged horizontally, and the needle head of the ignition needle is located above the nozzle.

[0015] The resulting technical effect is that the ignition needle can provide an ignition source to achieve smooth ignition of the stove.

[0016] Preferably, an annular groove is provided on the inner top of the fire bowl, and a fire outlet plate is connected to the annular groove.

[0017] Preferably, the air inlet elbow is a right-angle elbow.

[0018] The resulting technical effect is: bottom-side air intake effect can be achieved and the layout is compact. BRIEF DESCRIPTION OF THE DRAWINGS
