Abstract
Description
Technical Field
[0001] This utility model relates to the field of stove head technology, and in particular to a stove head with a specific flame shape. Background Technology
[0002] Existing stoves typically have small-diameter top vents, with more than eight vents. However, in actual use, it has been found that with small vents, the flames from the vents will spread outwards independently, resulting in poor aesthetics when used as outdoor bonsai landscapes. Utility Model Content
[0003] Therefore, in view of the above problems, this utility model proposes a stove head with a specific flame shape, which solves the technical problem that existing stove heads usually have small diameter vent holes at the top, and the flames from the vent holes will spread outward independently, resulting in poor aesthetics during use.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a furnace head with a specific flame shape, comprising a furnace tube, an opening on one side of the furnace tube, a sealing cap on the other side of the furnace tube for sealing the furnace tube, multiple air outlets on the outside of the furnace tube, and an air inlet in the middle of the furnace tube, wherein the diameter of the furnace tube is 5mm to 50mm.
[0005] Furthermore, the size of the air outlet is 2mm to 3.2mm.
[0006] Furthermore, there are 4 to 8 air outlets on the outer side.
[0007] Furthermore, the diameter of the air outlet is 2.6 mm.
[0008] Furthermore, there are 6 air outlets on the outside.
[0009] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0010] A burner head with a specific flame shape, using vent holes of 2-3.2mm in size, typically with a furnace tube diameter of 7-30mm, provides a calorific value of 0.9kW and 10,000-15,000 Btu when used with a valve. At this size and calorific value, the vent hole size is 2-3.2mm, with 4-8 vent holes on the outer side. Optimal, in actual testing, the vent hole size was 2.6mm, with 6 vent holes on the outer side. The resulting flame resembled a pine cone or strawberry shape. With a calorific value of 0.9kW, when the size of the air outlet is less than 2mm, the gas flows a long distance after exiting the outlet due to the small size, and will spread outward like petals. When the size of the air outlet is greater than 3.2mm, the flame burns a short distance after exiting the outlet due to the large size, and the flames from each outlet will gather upward into a ball, resembling a water droplet, resulting in a poor shape presentation and high gas consumption. This solves the technical problem of existing burners where the diameter of the top air outlet is small, causing the flames from the outlet to spread outward independently, resulting in poor aesthetics during use.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0020] refer to Figures 1 to 8This embodiment provides a furnace head with a specific flame shape, including a furnace tube 1, an opening 2 on one side of the furnace tube 1, a sealing cap 3 on the other side of the furnace tube 1 for sealing the furnace tube 1, a plurality of air outlets 4 on the outside of the furnace tube 1, and an air inlet 5 in the middle of the furnace tube 1. The diameter of the furnace tube 1 is 5mm to 50mm.
[0021] The diameter of the furnace tube 1 is typically 7mm to 30mm. When the burner head is used in conjunction with the valve, the calorific value is 0.9kW and 10,000 to 15,000 BTU. Under these dimensions and calorific values, the exhaust port 4 has a size of 2mm to 3.2mm, with 4 to 8 ports on its outer side. In the optimal state, during actual testing, the exhaust port 4 had a size of 2.6mm and 6 ports on its outer side. The flame will resemble a pine cone or strawberry shape, with a calorific value of 0.9kW. When the exhaust port 4 is smaller than 2mm, the gas flows a long distance after exiting the port, spreading outwards like flower petals. When the exhaust port 4 is larger than 3.2mm, the flame travels a short distance after exiting the port, causing the flames from each port to converge upwards into a teardrop shape, resulting in poor shape presentation and high gas consumption.
[0022] The size of the air outlet 4 is 2mm to 3.2mm, with an optimal operating diameter of 2.6mm. There are 4 to 8 air outlets on the outer side of the air outlet 4, with an optimal number of 6. The flames ejected from the air outlets extend outwards and then converge upwards. Compared to the operating shape with a diameter of less than 2mm, the flames are more concentrated. Compared to the operating shape with a diameter of more than 3.2mm, the flames do not clump together like water droplets or spread out like flower petals. The operating shape is optimal when the calorific value reaches 0.9kW.
[0023] The sealing cover is detachably connected to the furnace tube. A stud 3a is fixedly installed on the bottom surface of the sealing cover, and an arc-shaped block 4 is provided on the bottom surface of the sealing cover. The diameter of the arc-shaped block gradually decreases from bottom to top. A nut plate 4a threadedly connected to the stud is provided in the middle of the arc-shaped block. A conical block 4b is provided at the bottom of the arc-shaped block. A spring 4c is provided between the bottom surface of the arc-shaped block and the conical block. An arc-shaped air guide plate 4d is provided at the air outlet position of the arc-shaped block.
[0024] The position of the arc-shaped block can be adjusted according to the gas furnace being used. When the gas pressure is low, rotating the arc-shaped block causes the nut plate in the middle of the block to move downwards via the stud position, reducing the space at the top of the furnace tube. When gas enters the furnace tube, it is guided upwards by the conical block and then guided to the outlet by the arc-shaped air guide plate on top of the arc-shaped block, increasing the gas outflow speed. Furthermore, due to the guidance of the arc-shaped block, the gas will burn from bottom to top after passing through the outlet, moving towards the sides and center, with the flame converging at the top. Even when using a furnace tube with low gas pressure, it still has a good combustion effect. The position of the arc-shaped block can be adjusted by rotating it according to the gas pressure. The conical block is designed so that, because the arc-shaped block is close to the sealing cover, the spring on the top surface will push upwards when the gas passes through the conical block. The conical block guides the gas to a position close to the arc-shaped block and the outlet, directly guiding some of the gas to the outlet and reducing the amount of gas guided by the arc-shaped air guide plate, thus increasing the gas outflow speed.
