Description

Technical Field

[0001] This utility model relates to the technical field of gas equipment, specifically to a burner head with uniform flame output. Background Technology

[0002] To achieve a more uniform distribution of gas within the combustion chamber, resulting in better flame evenness and backfire prevention, burners with baffles within the combustion chamber have emerged on the market. The gas flow is thoroughly mixed by the baffles before exiting through the gas outlets. To further increase burner power, some burners, in addition to baffles, also feature upper and lower gas outlet groups on the burner cap. After passing through the baffles, the gas flow first flows to the upper gas outlet group and then to the lower gas outlet group. However, the gas flow tends to gravitate towards areas of lower resistance. Because the gas flows to the upper gas outlet group first, relatively less gas flows to the lower gas outlet group, affecting its gas output.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a burner head with uniform flame output. By setting a second vent on the gas baffle, a relatively larger amount of airflow can flow to the lower flame outlet under the action of the second vent, thereby making the gas output of the upper and lower flame outlets more uniform and avoiding insufficient gas output from the lower flame outlet.

[0005] The purpose of this utility model is achieved as follows:

[0006] A uniformly heated burner head includes a flame distribution base and a flame cover. The flame cover and the flame distribution base are connected to form a flame distribution chamber. The flame cover is provided with a flame outlet mechanism communicating with the flame distribution chamber. The flame outlet mechanism includes an upper flame outlet and a lower flame outlet. A gas baffle is provided in the flame distribution chamber at a position corresponding to the position between its air inlet end and the flame outlet mechanism. An outer flame distribution space is formed between the gas baffle and the flame outlet mechanism. An inner flame distribution space is formed between the gas baffle and the air inlet end of the flame distribution chamber. A first ventilation section is formed between the upper side of the gas baffle and the upper side of the flame distribution chamber. A second ventilation section is provided at a position corresponding to the lower side of the outer flame distribution space. The inner flame distribution space, the first ventilation section, the outer flame distribution space, and the upper flame outlet are sequentially connected to form a first gas outlet passage. The inner flame distribution space, the second ventilation section, the outer flame distribution space, and the lower flame outlet are sequentially connected to form a second gas outlet passage.

[0007] As a specific embodiment, the gas baffle is in the shape of a ring, and the lower side of the gas baffle is integrally formed with the flame distribution seat. The gas baffle is spaced from the inner side of the flame cap both vertically and radially.

[0008] As a specific embodiment, the upper and lower flame outlets are distributed circumferentially, and the upper and lower flame outlets are staggered circumferentially.

[0009] As a specific embodiment, the diameter of the upper flare outlet is larger than the diameter of the lower flare outlet.

[0010] As a specific embodiment, a guide surface is provided on the upper side of the corresponding fire chamber inside the burner cap. The guide surface is high in the middle and low on both sides. The highest point of the guide surface is located above the air baffle. The guide surface is inclined downward towards the inner and outer fire chambers.

[0011] As a specific embodiment, the center of the burner base is provided with an air inlet, and the burner chamber is arranged in a ring around the outer periphery of the air inlet. Several air intake channels are distributed between the air inlet and the burner chamber, and the air intake channels are respectively connected to the air inlet and the burner chamber.

[0012] As a specific embodiment, the second ventilation section includes a number of ventilation holes, which are distributed circumferentially to form a group of air holes. The air-blocking section has a number of groups of air holes distributed on it. The air-blocking section has an air-blocking structure between adjacent groups of air holes that allows the airflow to move circumferentially toward the group of air holes. The air-blocking structure is radially aligned with the air intake channel.

[0013] As a specific embodiment, the flame cap is provided with several thickened portions, which protrude upwards and outwards from the outer side of the flame cap.

[0014] As a specific embodiment, the number of thickened portions is four, which are evenly distributed circumferentially around the center position of the fire cover.

[0015] The beneficial effects of this utility model are:

[0016] By setting a second vent on the air baffle, a relatively larger amount of airflow can flow to the lower flame outlet under the action of the second vent, thereby making the air output of the upper and lower flame outlets more uniform and avoiding insufficient air output from the lower flame outlet.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] First embodiment:

[0025] See Figures 1-5 The uniformly flamed burner head includes a flame distribution seat 1 and a flame cover 2. The flame cover 2 and the flame distribution seat 1 are connected to form a flame distribution chamber 3. The flame cover 2 is provided with a flame outlet mechanism that communicates with the flame distribution chamber 3. The flame outlet mechanism includes an upper flame outlet 21 and a lower flame outlet 22. The upper flame outlet 21 and the lower flame outlet 22 can generate two layers of flame on the flame cover 2, which can relatively increase the overall combustion power of the burner head.

[0026] Inside the flame distribution chamber 3, a baffle 4 is provided at the position between its air inlet end and the flame outlet mechanism. The baffle 4 and the flame outlet mechanism form an outer flame distribution space 31, and the baffle 4 and the air inlet end of the flame distribution chamber 3 form an inner flame distribution space 32. When the gas enters the flame distribution chamber 3, under the action of the baffle 4, the airflow can diffuse more fully in the flame distribution chamber 3, thereby achieving a better flame equalization effect. The volume of the outer flame distribution space 31 is relatively smaller than that of the flame distribution chamber 3 as a whole, thereby increasing the pressure of the outer flame distribution space 31 and reducing the chance of backfire in the external flame.

[0027] A first ventilation section 41 is formed between the upper side of the air baffle 4 and the upper side of the flame distribution chamber 3. A second ventilation section 42 is provided on the lower side of the outer flame distribution space 31 corresponding to the air baffle 4. The inner flame distribution space 32, the first ventilation section 41, the outer flame distribution space 31 and the upper flame outlet 21 are connected in sequence to form a first air outlet passage. The inner flame distribution space 32, the second ventilation section 42, the outer flame distribution space 31 and the lower flame outlet 22 are connected in sequence to form a second air outlet passage. By setting the second ventilation section 42 on the air baffle 4, a relatively larger amount of airflow can flow to the lower flame outlet 22 under the action of the second ventilation section 42, thereby making the air outlet effect of the upper flame outlet 21 and the lower flame outlet 22 more uniform and avoiding the situation of insufficient air outlet of the lower flame outlet 22.

[0028] Furthermore, the gas baffle 4 is in the shape of a ring, and the lower side of the gas baffle 4 is integrally formed with the flame distribution seat 1. The gas baffle 4 forms a gap with the inner side of the flame cover 2 in both the vertical and radial directions. The gas baffle 4 does not require additional assembly, which simplifies the installation process of the burner head.

[0029] Furthermore, the upper flame outlet 21 and the lower flame outlet 22 are distributed circumferentially, and the upper flame outlet 21 and the lower flame outlet 22 are staggered circumferentially to make the flame outlet effect of the flame cap 2 more uniform in the circumferential direction.

[0030] Furthermore, the diameter of the upper flare hole 21 is larger than the diameter of the lower flare hole 22.

[0031] Furthermore, a guide surface 23 is provided on the upper side of the flame distribution chamber 3 inside the flame cap 2. The guide surface 23 is high in the middle and low on both sides. The highest point of the guide surface 23 is located above the air baffle 4. The guide surface 23 is inclined downward towards the inner flame distribution chamber 3 and the outer flame distribution chamber 3. The guide surface 23 can relatively reduce the volume of the upper side of the flame distribution chamber 3, thereby relatively increasing the airflow through the second air outlet passage, and further improving the uniform flame effect of the upper flame outlet 21 and the lower flame outlet 22.

[0032] Furthermore, an air inlet 11 is provided at the center of the ignition base 1, and the ignition chamber 3 is arranged in a ring around the outer periphery of the air inlet 11. Several air intake channels 12 are distributed between the air inlet 11 and the ignition chamber 3. The air intake channels 12 are connected to the air inlet 11 and the ignition chamber 3 respectively. The airflow enters the ignition chamber 3 through different air intake channels 12, which can make the gas flow rate at different positions in the ignition chamber 3 more uniform.

[0033] Furthermore, the flame cap 2 is provided with several thickened portions 24, which protrude upwards and outwards from the outside of the flame cap 2. The thickened portions 24 can improve the structural strength of the flame cap 2.

[0034] Furthermore, there are four thickened portions 24, which are evenly distributed around the center of the fire cover 2. The thickened portions 24 can also be used to support the support block 51 on the furnace frame 5.

[0035] Second embodiment:

[0036] See Figure 6 The difference between this embodiment and the first embodiment is that the second ventilation section 42 of the uniformly heated furnace head includes a plurality of ventilation holes, which are distributed circumferentially to form a group of ventilation holes. The gas-blocking section 4 is provided with a plurality of groups of ventilation holes. The gas-blocking section 4 is provided with a gas-blocking structure 43 between adjacent groups of ventilation holes, which enables the airflow to move circumferentially toward the direction of the group of ventilation holes. The gas-blocking structure 43 is radially aligned with the air intake channel 12. After the airflow enters the fire-distribution chamber 3 through the air intake channel 12, it will not directly pass through the second ventilation section 42 into the outer fire-distribution space 31 under the action of the gas-blocking structure 43, thus avoiding the airflow from concentrating at the position of the corresponding air intake channel 12 and entering the outer fire-distribution chamber 3, which would affect the uniform heating effect.

[0037] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.

[0038] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
