Description

Technical field

[0001] The utility model relates to a burner capable of adjusting the amount of air entering. [Background Technology]

[0002] In some current burners, high-pressure gas is ejected from a nozzle, generating a certain negative pressure at the inlet of the venturi tube, thereby drawing air from the atmosphere into the venturi tube.

However, existing burners cannot properly regulate the amount of incoming air, so the mixing ratio of gas and air cannot be properly configured, affecting the output pressure of the mixed gas, making the combustion conditions unstable, and easily causing incomplete combustion, affecting combustion efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1 to 4 As shown, a burner with adjustable air intake amount includes a gas distributor seat 1, on which is provided an ignition distributor 2, a gas input channel 11 for receiving gas, a plurality of nozzles 3 at one end of which are connected to the gas input channel 11 and can supply gas to be ejected, and an air regulating disk 4 that moves up and down along the nozzle 3. A plurality of venturi tubes 5 are provided in the ignition distributor 2, each of which has one end opposite to the jet end of the nozzle 3. An air intake gap 6 for air to enter the venturi tube 5 and mix with the gas is provided between the air intake end of the venturi tube 5 and the air regulating disk 4. The gas distributor seat 1 is provided with an air regulating device 7 that can drive the air regulating disk 4 to move so as to adjust the size of the air intake gap 6. The air regulating device 7 includes a stud 73 vertically arranged on the gas distributor seat 1 and a rotating lifting turntable 71 threadedly connected to the stud 73 and supported on the lower end surface of the air regulating disk 4. The utility model can adjust the size of the air intake gap through the air regulating device as needed, thereby controlling the amount of air entering, so that an appropriate amount of air is fully mixed with the fuel gas. In this way, the mixing ratio and output pressure of the mixed gas are appropriate when the mixed gas is output, promoting full combustion and flame stability.

[0023] Specifically, the rotary lift turntable 71 is provided with a toggle member 72 for manually toggling the rotary lift turntable 71 so that the rotary lift turntable 71 moves up and down along the stud 73. When adjustment is required, the toggle member 72 is manually grasped to drive the rotary lift turntable 71 to rotate, so that the rotary lift turntable 71 moves up and down along the stud 73. When the rotary lift turntable 71 moves upward along the stud 73 during rotation, the rotary lift turntable 71 drives the gas regulating plate 4 to rise, and at this time the air intake gap 6 becomes smaller; when the rotary lift turntable 71 is rotated in the opposite direction, the rotary lift turntable 71 moves downward along the stud 73 during rotation, and the gas regulating plate 4 also descends with the rotary lift turntable 71, and at this time the air intake gap 6 becomes larger, allowing more air to enter the venturi tube and mix with the gas.

[0024] In addition, an annular air-avoiding opening 40 is provided on the air-regulating disk 4, and one end of the toggle member 72 passes through the annular air-avoiding opening 40 and extends above the air-regulating disk 4. In this way, when the toggle member 72 is used to toggle the rotating lifting turntable 71, the toggle member 72 will not be blocked by the air-regulating disk 4, and adjustment is convenient.

[0025] Specifically, the stud 73 is hollow, with one nozzle 3 located inside the stud 73 and the remaining nozzles 3 located outside the stud 73. The gas regulating plate 4 includes a first gas regulating plate 41 that is sleeved on the stud 73 and a plurality of second gas regulating plates 42 that are located outside the first gas regulating plate 41 and sleeved on the nozzles 3 outside the stud 73. Adjacent second gas regulating plates 42 are connected by connecting ribs 43 to form a circle. An annular air escape 40 is located between the first gas regulating plate 41 and the second gas regulating plate 42. Through holes are provided in the middle of each of the first gas regulating plate 41 and the second gas regulating plate 42, respectively, for the stud 73 and the nozzle 3 to pass through. In a specific embodiment, the venturi tube 5 is also arranged in a one-to-one correspondence with the nozzle 3 within the ignition distributor 2.

[0026] Specifically, the rotary lift disc 71 includes an outer ring 712 supported on the lower end surface of the second air-regulating plate 42, an inner ring 713 disposed within the outer ring 712 and supported on the lower end surface of the first air-regulating plate 41, and a plurality of spokes 714 connected between the inner ring 713 and the outer ring 712. The toggle member 72 is rotatably mounted on one of the spokes 714. With this design, the rotary lift disc 71 has air passages formed between adjacent spokes 714, facilitating the supply of ambient air to the burner through these air passages.

[0027] In this burner, the gas distribution seat 1 is provided with a spring-pressing device 9 that can drive the gas regulating disk 4 to press against the rotating lifting turntable 71. The setting of the spring-pressing device 9 can make the gas regulating disk 4 always press against the rotating lifting turntable 71, avoiding the situation where the gas regulating disk 4 gets stuck and fails to move downward when the rotating lifting turntable 71 moves downward.

[0028] Specifically, the spring pressing device 9 includes a spring 91 which is sleeved outside two centrally symmetrical nozzles 3 , and the two nozzles 3 are provided with a supporting block 10 . The spring 91 is arranged between the upper end surface of the gas regulating disk 4 and the lower end surface of the supporting block 10 .

[0029] Specifically, the upper end of the nozzle 3 is provided with an external thread 31, and the supporting block 10 is provided with an internal thread 101 matching the external thread 31. The supporting block 10 is connected to the upper end of the nozzle 3 by threads, which can facilitate the assembly of other components.

[0030] like Figure 4 As shown, the stud 73 is detachably connected to the gas distributor 1 via a connecting portion 731. The connecting portion 731 is provided with an air supply hole 732 that communicates with the inner cavity of the stud 73. The gas distributor 1 and the stud 73 are designed as separate components, facilitating fabrication. The connecting portion 731 can be screwed onto the gas distributor 1, and the air supply hole 732 allows air to be replenished into the stud 73, ensuring sufficient air around the nozzle 3 located within the stud 73, thus preventing incomplete combustion of the gas in the middle of the burner.
