[0035] The technical scheme of the utility model will be described clearly and completely below. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the skilled in the art without creative labor belong to the protection scope of the utility model.

[0036] EMBODIMENT

[0037] Referring to the accompanying Figures 1-5 A novel energy-saving boiler head for burning charcoal, comprising:

[0038] The base 10 is a rectangular and hollow structure; a plurality of ventilation holes 11 are spaced apart on the top of the base 10, and an air inlet pipe 12 is arranged at the bottom of the base 10 and communicates with the inside of the base 10; wherein the hole diameter of the ventilation hole 11 gradually decreases from inside to outside; more specifically, the ventilation hole 11 includes a first ventilation hole 111 and a second ventilation hole 112, the first ventilation hole 111 is spaced apart and arranged at the position near the edge of the top of the base 10; the second ventilation hole 112 is spaced apart and arranged at the middle position of the top of the base 10, and the density of the second ventilation hole 112 is greater than that of the first ventilation hole 111;

[0039] The ignition cover 20 is fixed to the top of the base 10 and has a feeding port 21 on the front side; the two sides and the top of the rear side of the ignition cover 20 are inclined outward, so that the novel energy-saving boiler head for burning charcoal in the embodiment has a bow shape; in addition, in the embodiment, a dust screen 22 is fixed at the position on both sides of the feeding port 21 of the ignition cover 20, and an exhaust slot 23 is arranged at the position of both ends of the top of the rear side of the ignition cover 20;

[0040] The support rod 30 is fixed to the inner wall of both sides of the ignition cover 20 and close to the bottom of the ignition cover 20;

[0041] The support 40 is symmetrically arranged on the inner wall of both sides of the ignition cover 20 and close to the top of the ignition cover 20; the support 40 includes at least two support plates 41 hinged to each other, one of which is hinged to the ignition cover 20 close to one side of the ignition cover 20; when the support plates 41 of the two supports 40 are horizontally unfolded, the support 40 will block the top of the ignition cover 20. In addition, the communication hole 411 is arranged on the support plate 41.

[0042] In the embodiment, the air inlet end of the air inlet pipe 12 is connected to an external air blower.

[0043] The new wood-burning energy-saving boiler head in the embodiment can effectively avoid the wood from blocking the first ventilation hole 111 and the second ventilation hole 112, thereby facilitating the full and uniform combustion of the wood. In addition, during the combustion process, the external air blower blows air into the hollow structure of the base 10 through the air inlet pipe 12, and the air is then sprayed out of the first ventilation hole 111 and the second ventilation hole 112. Since the diameter of the ventilation hole 11 gradually decreases from the inside to the outside, this design can increase the impact force of the air sprayed out of the first ventilation hole 111 and the second ventilation hole 112, increase the air flow rate, and thereby increase the probability of the wood contacting with oxygen, which is helpful to improve the combustion effect of the wood. At the same time, the strong air can blow away the ash layer formed on the surface of the wood after combustion, reduce the effect of the ash layer on blocking the air, and thereby make the wood fully and completely burn. In addition, the blown-off ash layer is blown to the outside of the fire hood 20, avoiding the accumulation of the ash layer at the base 10 to block the ventilation hole. The ash removal plate 22 arranged on both sides of the feeding port 21 and the first ventilation hole 111 at this position can effectively reduce the blowing-out of the ash layer from the feeding port 21.

[0044] In the embodiment, the outer side of the exhaust slot 23 of the fire hood 20 is a chimney opening. The arrangement of the exhaust slot 20 can make the airflow in the fire hood 20 more smooth, and can effectively avoid the airflow in the fire hood 20 flowing in the direction of the feeding port 21, thereby effectively avoiding the blowing-out of the ash layer from the feeding port 21.

[0045] Secondly, in the embodiment, the support member 40 is additionally arranged. When the wood is normally combusted, the two support plates 41 in the support member 40 are in a folded state and are attached to the inner wall of the fire hood 20. When it is necessary to reduce the fire or extinguish the fire, the two support plates 41 are horizontally unfolded. In this way, the support plates 41 are pressed on the top of the wood, which can achieve the effect of reducing the fire or extinguishing the fire. Of course, when the support plates 41 are horizontally unfolded, sweet potatoes, tin paper wrapped with chicken or other foods can be placed on the top of the support plates, so as to achieve the effect of roasting sweet potatoes and roasting chicken, which can fully utilize the residual heat of the wood and enrich the functionality of the device.
