Description

Technical Field

[0001] This utility model relates to the field of heater technology, and in particular to an outdoor heater with a wind deflector. Background Technology

[0002] Heaters are mainly used for heating in well-ventilated indoor or outdoor spaces, and are mostly used for patio parties and outdoor camping.

[0003] For example, patent CN207394961 U discloses a portable gas heater and barbecue appliance. A piezoelectric igniter, a Z-shaped connecting pipe, a gas control valve, a burner assembly, a tilt switch, an ignition needle, and a thermocouple are housed within a cylindrical space formed by a lower end cover, a mesh cover, and a top cover. The mesh cover, heat distribution plate, and top cover constitute the mesh cover assembly. The piezoelectric igniter lever and the shaft of the gas control valve are exposed outside the lower end cover of the mesh cover. Gas flows through an inlet hose, an inlet connector, and a Z-shaped connecting pipe to the gas control valve. The gas flow is controlled by pressing and rotating the valve body knob. When the gas control valve is opened, gas is ejected from the nozzle and enters the burner head at the top of the burner assembly. Simultaneously, pressing the piezoelectric igniter causes the ignition needle to release an electric spark, igniting the burner flame. The flame burns within the cylindrical space formed by the lower end cover and the mesh cover assembly.

[0004] The problem with the above technology is that the ignition needle in the existing technology is set in a cylindrical space. In order to ensure complete combustion, the cylindrical space is connected to the outside. When the heater is used outdoors, the flame generated by the ignition needle is easily affected by the wind, making it difficult to ensure stable combustion.

[0005] To address these technical problems, an outdoor heater with a wind deflector is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an outdoor heater with a wind deflector, which can prevent the flame generated by the ignition needle from being affected by the wind and ensure the stability of the flame combustion.

[0007] The technical solution adopted by this utility model to solve the problem is: an outdoor heater with a wind deflector, comprising a main body, wherein a gas supply device and an ignition device are provided inside the main body, a combustion hood is provided on the top of the main body, the ignition device includes a thermocouple and an ignition needle, an opening is provided on the top of the main body, the thermocouple and the ignition needle pass through the opening and are located on the top of the main body and outside the combustion hood, the gas supply device includes a combustion head, the end of the combustion head passes through the opening and is located between the thermocouple and the ignition needle, and a wind deflector is also provided, the wind deflector is provided on the top of the main body and covers the thermocouple, the ignition needle and the combustion head.

[0008] As a further improvement to the above technical solution, a slot is provided on the side of the opening, and a locking block is provided at the bottom of the wind deflector, the locking block being inserted into the slot.

[0009] As a further improvement to the above technical solution, the side edge of the card block extends outward with a protrusion, and a limiting groove is formed between the protrusion and the bottom edge of the wind deflector.

[0010] As a further improvement to the above technical solution, the cross-section of the wind deflector is arc-shaped.

[0011] As a further improvement to the above technical solution, a mounting bracket is fixedly connected inside the main body, and a mounting groove is provided on the mounting bracket. The thermocouple, ignition needle and burner head are all mounted on the mounting groove.

[0012] As a further improvement to the above technical solution, the ignition device includes a rotary switch, a micro switch, and a cam rotatably connected to the rotary switch. The micro switch is electrically connected to the ignition needle. The gas delivery device includes a solenoid valve communicating with the combustion head. A valve stem is elastically connected to the end of the solenoid valve. A first abutment portion and a second abutment portion are respectively provided at the upper and lower ends of the cam. A torsion spring is provided between the valve stem and the first abutment portion. The second abutment portion is located beside the micro switch.

[0013] As a further improvement to the above technical solution, a flameout protector is electrically connected between the solenoid valve and the thermocouple.

[0014] As a further improvement to the above technical solution, the gas delivery device includes an air inlet and a nozzle connected to a solenoid valve. The air inlet faces the bottom of the main body, and the nozzle faces the bottom of the combustion hood and is connected to the combustion hood.

[0015] The beneficial effects of this utility model are: when in use, the thermocouple and ignition needle will ignite the gas at the burner head, thereby igniting the gas inside the combustion hood. By covering the thermocouple, ignition needle and burner head with a wind deflector, the external wind force can be prevented from affecting the flame at the burner head, thus ensuring the stability of the flame combustion.

[0031] When in use, the thermocouple 31 and the ignition needle 32 ignite the gas at the burner head 41, thereby igniting the gas inside the combustion shroud 2. The wind deflector 5 covering the thermocouple 31, the ignition needle 32 and the burner head 41 can prevent external wind from affecting the flame at the burner head 41 and ensure the stability of the flame combustion.
