[0002] Burner is a general term for a device that sprays fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium.

[0003] The existing burners cannot effectively control the amount of gas during use. When the burner is used, when the amount of gas is large, the flame will be larger, and when the gas is small, the flame will be smaller. Therefore, the size of the flame cannot be controlled according to specific usage conditions, which is inconvenient for people to use. Utility Model Content

[0020] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1

[0022] like Figure 1 - Figure 6 As shown, a proportional regulation burner comprises a burner body 1, and a flame-spraying tube 2 arranged at one side of the burner body 1, a connecting tube 3 communicating with the inside of the burner body 1 is installed at one side of the burner body 1, a gas pipe 4 is installed at one side of the connecting tube 3, a sealing plate 6 is installed inside the connecting tube 3, a plurality of strip openings 13 arranged in an annular manner are opened on the sealing plate 6, a plurality of groups of regulating mechanisms used in conjunction with the plurality of strip openings 13 are installed inside the connecting tube 3 to adjust the size of the strip openings 13, the regulating mechanism comprises a baffle 10 located inside the connecting tube 3, a working box 5 installed outside the connecting tube 3, and a moving mechanism installed inside the working box 5 and driving the baffle 10 to move, the moving mechanism comprises a rack 9 installed at one side of the baffle 10, a first gear 8 installed inside the working box 5 and meshing with the rack 9, and a gear 8 installed on the working box 5. 5 and drives the first gear 8 to rotate. The interior of the working box 5 is provided with an opening for the rack 9 to move. The rotating mechanism includes a second gear 7 installed on the inner wall of the working box 5 and meshing with the plurality of first gears 8. The second gear 7 is in an annular structure. A rotating motor 15 is installed on the outside of the working box 5 to drive one of the first gears 8 to rotate. One side of the baffle 10 extends to the outside of the connecting pipe 3, and a limiting mechanism for limiting the baffle 10 is installed on the outside of the connecting pipe 3. The limiting mechanism includes a fixing plate 11 installed on one side of the baffle 10, a spring 12 installed on one side of the fixing plate 11, one end of the spring 12 is fixedly connected to the outside of the connecting pipe 3, one side of the baffle 10 is in contact with one side of the sealing plate 6, and the positions of the plurality of baffles 10 correspond to the positions of the plurality of strip openings 13. The width and length of the sealing plate 6 are both greater than the strip openings 13.

[0023] It should be noted that, in this type of proportional regulation burner, when in use, the gas will enter the interior of the connecting pipe 3 through the gas pipe 4, and then enter the interior of the burner body 1 through the connecting pipe 3 and mix with the air. When the gas flow needs to be increased, the rotating motor 15 will drive one of the first gears 8 to rotate, and the second gear 7 will rotate under the drive of the first gear 8. Under the rotation of the second gear 7, multiple first gears 8 will rotate at the same time. At this time, under the cooperation of the first gear 8 and the rack 9, the rack 9 will drive the baffle 10 to move, so that the multiple baffles 10 are away from the sealing plate 6. , thereby expanding the opening of the strip port 13 and increasing the flow rate of the gas. When the flow rate of the gas needs to be reduced, the rotating motor 15 will rotate in the opposite direction. According to the above working principle, multiple baffles 10 will move toward the center of the sealing plate 6, thereby reducing the opening of the strip port 13 and reducing the flow rate of the gas. By changing the size of the vent of the strip port 10, the flow rate of the gas can be adjusted, and then the proportion of the gas can be adjusted. In this way, the size of the flame can be effectively controlled during use, which is more convenient for people to use.

[0024] Example 2

[0025] like Figure 1 - Figure 6 Detailed description is given of a proportional regulating burner, wherein a filter screen 14 is installed inside the strip-shaped opening 13 , and one side of the baffle 10 is in contact with one side of the filter screen 14 .

[0026] It should be noted that this kind of proportional regulation burner can filter the gas through the filter 14 when in use, so that the ash in the gas can be filtered out, thereby avoiding the impact of large ash emissions on the environment, and because the baffle 10 is in contact with one side of the filter 14, when the filter 14 needs to be cleaned, the baffle 10 can be moved according to the working principle of Example 1. When the baffle 10 moves, one side of the filter 14 can be cleaned, which is more convenient for people to use.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
