Description

Technical Field

[0001] This utility model relates to the field of ceramic furnace head technology, specifically a high-efficiency ceramic furnace head. Background Technology

[0002] In the construction of gas stoves, the burner head is a crucial component. The combustion of fuel, the direction and shape of the flame, as well as the exhaust gas discharge and distribution in the heat exchange chamber, are all related to the burner head's construction. Burner heads are generally made of cast iron and ceramic. Natural gas is connected to the gas pipe in the burner head, and oxygen is drawn in using a siphon. Ignition is achieved by placing an ignition needle on one side of the nozzle, which then sprays the gas through the nozzle on the burner head for combustion. The flame intensity of the burner head is adjusted by regulating the gas intake at the gas inlet. Existing high-pressure gas burners have extremely fast gas flow rates, short gas delivery pipelines, and limited gas chamber space in the burner head. Therefore, gas and air are often delivered to the flame holes for combustion before they are fully mixed, resulting in incomplete combustion and poor combustion efficiency, such as red or yellow flames.

[0003] To address the aforementioned deficiencies, existing technology (Chinese patent announcement number CN201748494U, announcement date 2011-02-16) provides a multi-burner infrared ceramic stove head. This multi-burner infrared ceramic stove head includes a stove head body with a furnace cavity inside; it also includes an air mixing pipe, air inlet holes, a valve body air inlet nozzle, a ceramic sleeve, and a multi-burner infrared ceramic burner. The ceramic sleeve is fixed to the surface of the stove head body, and the infrared ceramic burner is located inside the ceramic sleeve. The air mixing pipe is connected to the stove head body and communicates with the furnace cavity. The valve body air inlet nozzle is inserted into the end of the air mixing pipe and has multiple air inlet holes, which can fully mix the gas and air, resulting in more complete combustion. Furthermore, the ceramic sleeve nozzle is trumpet-shaped, and the infrared ceramic burner is thick and robust, resulting in more uniform gas spray, stronger force, and higher durability.

[0004] In the above scheme, gas and air are directly introduced into the gas chamber through the air mixing pipe and mixed by diffusion during gas flow. The mixing efficiency of gas and oxygen is low, which can easily lead to incomplete combustion. There is also a lack of guiding mechanism between the gas chamber and multiple ceramic burners, making it difficult to balance the firepower of each burner during combustion. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency ceramic burner head to solve the problems mentioned in the background art. In the process of use, the gas and air are directly introduced into the gas chamber through the air mixing pipe and mixed by the diffusion of the gas itself during the flow. The mixing efficiency of gas and oxygen is low, which easily leads to incomplete combustion. There is also a lack of guiding mechanism between the gas chamber and multiple ceramic burners, which makes it difficult to balance the firepower of each burner during combustion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency ceramic burner head, including a burner head body, a ceramic combustion rack mounted on the top of the burner head body, a sealing boss at the connection between the burner head body and the ceramic combustion rack, flame holes at equal angles on the top of the ceramic combustion rack, a gas chamber in the middle of the top surface of the burner head body, a gas pipe connected to the bottom of the gas chamber, and an air intake component at the bottom of the burner head body;

[0007] A mixing chamber is provided between the gas chamber of the burner body and the gas pipe, and a uniform mixing component is provided in the mixing chamber to fully mix the gas and air.

[0008] The gas chamber is equipped with a buffer and flow guiding component to prevent the airflow from directly impacting the ceramic burner and to ensure that the airflow is evenly distributed to the ceramic burner.

[0009] Furthermore, the bottom of the ceramic combustion rack is concave, and the bottom of the ceramic combustion rack forms a nested sealing structure with the ceramic combustion rack through a sealing boss, the cross-section of which is "L" shaped.

[0010] Furthermore, the air intake component includes an annular groove formed at the bottom of the burner body, an air ring installed in the groove, and an air jet pipe installed at an equal angle inside the air ring. The air jet pipe is inclined upward and its outlet extends into the interior of the mixing chamber.

[0011] Furthermore, the uniform mixing component includes a baffle plate mounted on the inner wall of the mixing chamber, the baffle plate being configured in a spiral shape.

[0012] Furthermore, an air passage is provided between the top of the mixing chamber of the buffer guide assembly and the gas chamber, and the air passage delivers the uniformly mixed gas and air into the gas chamber.

[0013] Furthermore, the buffer guide assembly includes a flow divider installed in the middle of the bottom surface of the air chamber. The flow divider is configured as a conical structure with the tip of the cone pointing downwards, and the side of the flow divider faces the top of the air passage.

[0014] Furthermore, the outer perimeter of the flow divider is provided with guide plates of equal height, the guide plates are configured with an arc-shaped structure, and the guide plates are radially distributed on the inner bottom of the air chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This high-efficiency ceramic burner, during use, allows air and gas to be evenly mixed and then passed through a baffle plate in the mixing chamber before being introduced into the gas chamber. The buffer guide component in the gas chamber disperses the direct airflow into a diffused airflow along the conical surface, preventing the airflow from directly impacting the ceramic plate combustion section. At the same time, the dispersed airflow is evenly distributed to the bottom of the ceramic burner and finally ejected from the flame hole, resulting in complete combustion and a uniform flame.

[0017] Furthermore, the sealing boss achieves nested sealing with the burner body to prevent gas leakage. The tilt angle of the jet pipe creates a rotating airflow when air enters, expanding the contact area with the gas. The gas enters the mixing chamber through the gas pipe and mixes thoroughly with the air introduced by the gas ring through the jet pipe under the action of the spiral baffle, improving the mixing uniformity and avoiding the phenomenon of red or yellow flames caused by local oxygen deficiency.

[0018] Furthermore, the conical diffuser with its tip pointing downwards disperses the direct airflow into radial airflow along the conical surface, offsetting the airflow impact pressure and preventing the flame holes of the ceramic burner from producing floating or flying flames due to direct impact. The radial arc-shaped guide plate on the outside of the diffuser further guides the dispersed airflow, allowing the airflow to flow evenly along the inner wall of the gas chamber to the bottom of the ceramic burner, ultimately resulting in uniform firepower when ejected from the flame holes.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figure 1 - Figure 2 and Figure 5 As shown, this utility model provides the following technical solution: a high-efficiency ceramic burner head, including a burner head body 1, a ceramic combustion rack 2 mounted on the top of the burner head body 1, a sealing boss 3 at the connection between the burner head body 1 and the ceramic combustion rack 2, flame holes 4 at equal angles on the top of the ceramic combustion rack 2, a gas chamber 5 in the middle of the top surface of the burner head body 1, a gas pipe 6 connected to the bottom of the gas chamber 5, an air intake component at the bottom of the burner head body 1, a mixing chamber 7 between the gas chamber 5 and the gas pipe 6, a uniform mixing component for fully mixing gas and air in the mixing chamber 7, and a buffer guide component inside the gas chamber 5 to prevent airflow from directly impacting the ceramic combustion rack 2 and to evenly distribute the airflow to the ceramic combustion rack 2.

[0028] In use, the ceramic burner 2 serves as the combustion center, supported on the burner body 1. It is nested and sealed with the burner body 1 through the sealing boss 3 (to prevent gas leakage). The gas enters the mixing chamber 7 through the gas pipe 6, and is fully mixed with the air introduced by the air intake component in the mixing chamber 7 and delivered to the gas chamber 5. After being guided by the buffer guide component in the gas chamber 5, it is evenly dispersed to the bottom of the ceramic burner 2 and finally sprayed out from the flame hole 4 for combustion, thus solving the problems of insufficient mixing and uneven firepower in traditional burners.

[0029] Example 2:

[0030] Based on Embodiment 1, a gas-air uniform mixing mechanism is also disclosed to avoid incomplete combustion and poor combustion efficiency caused by insufficient mixing, such as red or yellow flames. Please refer to [link / reference]. Figure 2 - Figure 2 and Figure 5 - Figure 6As shown, its specific structure is as follows: The bottom of the ceramic burner 2 is set to be concave, and the bottom of the ceramic burner 2 forms a nested sealing structure with the ceramic burner 2 through the sealing boss 3. The cross section of the sealing boss 3 is set to an "L" shaped structure. The air intake component includes an annular groove 8 opened at the bottom of the burner body 1. An air ring 9 is installed in the groove 8. An air jet pipe 10 is installed at an equal angle inside the air ring 9. The air jet pipe 10 is set to be inclined upward. The outlet of the air jet pipe 10 penetrates into the interior of the mixing chamber 7. The uniform mixing component includes a baffle plate 11 installed on the inner wall of the mixing chamber 7. The baffle plate 11 is set to a spiral structure.

[0031] like Figure 5 - Figure 6 As shown, during use, the tilt angle of the jet pipe 10 causes the air to form a rotating airflow when it enters, expanding the contact area with the gas. The gas enters the mixing chamber 7 through the gas pipe 6 and mixes fully with the air introduced by the gas ring 9 through the jet pipe 10 under the action of the spiral baffle 11. The spiral baffle 11 on the inner wall of the mixing chamber 7 disturbs the gas-air mixture airflow, forcing the airflow to flow along the spiral path, extending the mixing path, and allowing the gas and air molecules to collide and diffuse fully, improving the mixing uniformity and avoiding the problems of red or yellow flames caused by local oxygen deficiency in traditional "direct mixing" burners.

[0032] Example 3:

[0033] Based on Embodiment 2, a buffer and flow guiding mechanism is also disclosed to prevent the airflow from directly impacting the ceramic burner 2, while ensuring that the dispersed airflow is evenly distributed to the bottom of the ceramic burner 2. Please refer to [reference needed]. Figure 4 - Figure 5 As shown, its specific structure is as follows: An air passage 12 is provided between the top of the mixing chamber 7 of the buffer guide assembly and the gas chamber 5. The air passage 12 delivers the uniformly mixed gas and air to the gas chamber 5. The buffer guide assembly includes a flow divider 13 installed in the middle of the bottom surface of the gas chamber 5. The flow divider 13 is a conical structure with the tip of the cone pointing downwards. The side of the flow divider 13 faces the top of the air passage 12. The outer perimeter of the flow divider 13 is provided with guide plates 14 of equal height. The guide plates 14 are arc-shaped and are radially distributed on the inner bottom of the gas chamber 5.

[0034] like Figure 4 - Figure 5As shown, during use, the mixed gas and air enter the gas chamber 5 through the air passage 12 at the top of the mixing chamber 7. The conical diverter 13 in the middle of the bottom surface of the gas chamber 5, with its tip pointing downwards, can disperse the direct airflow into radial airflow along the conical surface, offsetting the airflow impact pressure and preventing the flame hole 4 of the ceramic burner 2 from producing floating or flying flames due to direct impact. The radial arc-shaped guide plate 14 on the outside of the diverter 13 further guides the dispersed airflow, so that the airflow flows evenly along the inner wall of the gas chamber 5 to the bottom of the ceramic burner 2, and finally the flame is uniform when it is sprayed out from the flame hole 4.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
