[0015] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination can be formed between the following-described embodiments or technical features to form a new embodiment.

[0016] A fully premixed combustion head is provided with a combustion component and an assembly component. The assembly component is an assembly plate 1, and an assembly head 2 is arranged on the assembly plate 1. The assembly head 2 and the assembly plate 1 are fixed by welding. An assembly thread is arranged on the inner wall of the assembly head 2. A combustion component is arranged on one side of the assembly plate 1. The combustion component is a combustion head 3. An air inlet pipe 4 and an ignition component 5 are arranged in the combustion head 3. A suspension 5 is arranged on the air inlet pipe 4, and the suspension 5 is fixed on the inner wall of the combustion head. An assembly space is arranged on the suspension 5, and the air inlet pipe 4 is arranged in the assembly space. A flame spraying component is arranged outside the combustion head 3.

[0017] When flame spraying operation needs to be carried out, natural gas can be transported by using the air inlet pipe, and then ignition is carried out by using the ignition component. After ignition, flames are generated. These flames need to be divided to avoid the flames being too concentrated. Therefore, a flame spraying component can be arranged on the combustion head 3, and the flame spraying component is used for flame division. The flame spraying component is a flame spraying port 6, and a flame spraying hole 7 is arranged on the flame spraying port 6. The flame spraying holes 7 are distributed at the flame spraying port, and the flames are divided from inside the flame spraying holes 7. In this way, the flame can be divided, so that the combustion area of the combustion head 3 is further extended, meeting the working needs of the combustion head 3 for heating water source in the boiler.

[0018] When the combustion head 3 is assembled, the assembly plate 1 needs to be used for assembly. An assembly head 2 is arranged on the assembly plate 1, and a thread is arranged on the inner wall of the assembly head 2. By using the thread on the inner wall of the assembly head 2 for thread assembly with the conveying pipe, the assembly of the combustion head 2 can be made more stable. In order to make the assembly between the combustion head 3 and the conveying pipe more compact, a filling component can be arranged on the inner side of the assembly plate 1. The filling component is a filling washer 8, and the filling washer 8 is distributed on one side of the assembly plate. By using the filling washer, the filling between the combustion head 3 and the conveying pipe can be made more compact, further enhancing the sealing performance between the combustion head 3 and the conveying pipe.

[0019] When the combustion head is performing combustion operation, ignition needs to be carried out by relying on the ignition component 5. The ignition component 5 can ignite natural gas, enabling the combustion head 3 to eject flames, meeting the combustion needs of the combustion head. Generally, the ignition component 5 is an ignition head, and the ignition head is an electromagnetic pulse ignition head, and the electromagnetic pulse ignition head is located inside the combustion head 3.
