Description

Technical Field

[0001] The present invention relates to the technical field of burners, and in particular to a three-ring burner with flameout protection. Background Art

[0002] The function of the burner is to transport the mixed gas from the ejector to the inner and outer fire covers, and finally flow out from the fire hole and burn in the atmosphere. The three-ring burner head on the market has three independent ejectors and three partial fire covers: inner, middle, and outer. Moreover, since the three rings of flame of this three-ring burner are controlled by corresponding control valves, the flames of the three rings can be adjusted separately by rotating the corresponding control valves. However, due to the certain distance between the three partial fire covers, the traditional flameout protection needle can only be installed between two of the fire covers, resulting in a detection "blind spot" for the flameout protection needle. Such a structure will result in the following situation: when the fire rings on both sides of the flameout protection needle are extinguished, the flameout switch is accidentally activated, resulting in the need to reopen the flameout switch valve when the remaining fire rings need to be ignited separately. This requires frequent operation of the flameout switch valve during use, which is more troublesome and poses a safety hazard. Summary of the Invention

DETAILED DESCRIPTION

[0015] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0016] Combine Figures 1 to 3 A three-ring burner with flameout protection is shown, which has a burner body 2, and the burner body 2 can have at least one fire ring in a constantly ignited state during use. The three-ring burner includes a first control valve 3 and a second control valve 4. A flameout protection needle 6 is passed through the burner body 2, and the flameout protection needle 6 is located on one side of the fire ring in a constantly ignited state. The first control valve 3 is connected to the flameout protection needle 6 through a first signal line 7, and the second control valve 4 is connected to the flameout protection needle 6 through a second signal line 10. In this embodiment, the outer fire ring, the inner fire ring and the central fire ring are controlled by the first control valve 3 and the second control valve 4, so that one of the fire rings is in a constantly ignited state, thereby facilitating the detection of the flameout protection needle 6 located on one side of the fire ring in a constantly ignited state, preventing accidental activation of the flameout protection switch during use, making it more convenient to use, and the flameout protection needle 6 can simultaneously feed back signals to the first control valve 3 and the second control valve 4, which is safer.

[0017] The burner body 2 of this embodiment is mounted on the base 1, and the first nozzle seat 18, the second nozzle seat 19 and the third nozzle seat 20 are respectively installed on one side of the base 1. The burner body 2 is provided with an outer fire ring 13, an inner fire ring 14 and a central fire ring 15. The first nozzle seat 18 is connected to the ejection tube of the outer fire ring 13, the second nozzle seat 19 is connected to the ejection tube of the central fire ring 15, and the third nozzle seat 20 is connected to the ejection tube of the inner fire ring 14. The central fire ring 15 is a fire ring that is always in a burning state, and the flameout protection needle 6 is located on one side of the central fire ring 15; the outer fire ring 13, the inner fire ring 14 and the central fire ring 15 are connected through the corresponding nozzle seats, so that the first control valve 3 and the second control valve 4 are respectively connected to the corresponding nozzle seats, thereby realizing that the central fire ring 15 forms a fire ring that is always in a burning state.

[0018] Specifically, the first control valve 3 is connected to the first air pipe 8 and the second air pipe 9, the first air pipe 8 is connected to the first nozzle seat 18, the second air pipe 9 is connected to the second nozzle seat 19, the second control valve 4 is connected to the third air pipe 11 and the fourth air pipe 12, the third air pipe 11 is connected to the third nozzle seat 20, and the fourth air pipe 12 is connected to the second nozzle seat 19; wherein, the second nozzle seat 19 has two input ends, so that the second air pipe 9 and the fourth air pipe 12 are both connected to the input end of the second nozzle seat 19. During use, even if the outer fire ring 13 or the inner fire ring 14 is opened to ignite the fire ring, the center fire ring 15 is still in a ignited state. Therefore, as long as the fire ring of the center fire ring 15 is accidentally extinguished, the flameout protection needle 6 detects the extinction and can feed back a signal to the first control valve 3 and the second control valve 4 to facilitate the activation of the flameout protection switch, which is highly safe.

[0019] It is worth noting that a needle seat 5 is provided on the base 1 of this embodiment, and the flameout protection needle 6 is installed in the needle seat 5, so that when the burner body 2 is disassembled separately, the flameout protection needle 6 does not need to be disassembled, which makes cleaning more convenient.

[0020] In this embodiment, a first air supply hole 16 is provided between the outer fire ring 13 and the inner fire ring 14, a second air supply hole 17 is provided between the inner fire ring 14 and the center fire ring 15, and the flameout protection needle 6 is located in the second air supply hole 17; the first air supply hole 16 and the second air supply hole 17 can provide a secondary air supply channel for the outer fire ring 13 or the inner fire ring 14 and the center fire ring 15, so that the flame burns more fully.

[0021] It should also be noted that the upper surface of the central fire ring 15 of this embodiment is a slope, on which a plurality of fire holes are opened, and the slope corresponds to the flameout protection needle 6; this can improve the detection accuracy of the flameout protection needle 6 when the flame is burning, and further improve safety.

[0022] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
