Description

Technical Field

[0001] This utility model relates to the field of gas burner technology, specifically, to a ignition tube and burner head that are easy to clean. Background Technology

[0002] Currently, the burner head of commercial stoves is a commonly used type of stove. These stoves typically use locking screws to secure the ignition tube, ensuring that the flame does not go out during use. This allows for easy and quick ignition of the premixed gas in the combustion chamber.

[0003] However, existing ignition tubes are fixed inside the burner head. During use, food juice or oil stains often accumulate on the ignition tube, causing it to go out easily. When cleaning, the ignition tube needs to be loosened from the burner head before it can be removed for cleaning, which is quite troublesome. Utility Model Content

[0004] In order to overcome the defects of the existing technology, this utility model provides an easy-to-clean ignition tube and burner head, aiming to solve the above-mentioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an easy-to-clean ignition tube, including a tube body, an installation cylinder sleeved on the tube body, the installation cylinder being installed in the furnace body, an exhaust nozzle being detachably installed at one end of the tube body, a limiting part installed on the tube body on one side of the exhaust nozzle, and the tube body being movably arranged inside the installation cylinder so that the limiting part and the exhaust nozzle extend out of or retract into the installation cylinder.

[0006] In the aforementioned easy-to-clean ignition tube, the limiting part includes a first limiting ring and a second limiting ring. The first limiting ring and the second limiting ring are fixed on the tube body in an up-down distribution. The lower end face of the air outlet nozzle contacts the upper end face of the first limiting ring, and the second limiting ring can be snapped into the mounting cylinder.

[0007] In the aforementioned easy-to-clean ignition tube, the outer walls of both the upper and lower ends of the tube body are provided with external thread sections. One end of the air outlet nozzle is threaded onto the external thread section at the upper end of the tube body. A first air outlet hole is opened on the upper end face of the air outlet nozzle. A second air outlet hole is evenly opened in the circumferential direction of the air outlet nozzle. When the lower end face of the air outlet nozzle is in contact with the upper end face of the first limiting ring, the upper end face of the tube body is lower than the second air outlet hole.

[0008] In the aforementioned easy-to-clean ignition tube, the mounting cylinder is hollow, with an opening at the upper end and a bottom cover at the lower end. The bottom cover has a tube hole that can accommodate the tube body, and the outer diameter of the second limiting ring is larger than the inner diameter of the tube hole.

[0009] A burner head includes the aforementioned ignition tube, a combustion chamber is provided inside the burner body, a cylindrical mounting groove is provided on one side of the combustion chamber on the burner body, the mounting cylinder is inserted into the cylindrical mounting groove, and an ignition needle and a sensing needle corresponding to the gas outlet nozzle are respectively provided on both sides of the cylindrical mounting groove.

[0010] The beneficial effects of this utility model are as follows: by installing the mounting cylinder inside the furnace body, the gas nozzle of the tube body is locked inside the mounting cylinder by the limiting part when the tube body is in use. When it is necessary to clean the ignition tube, simply lift the tube body so that the limiting part and the gas nozzle extend out of the mounting cylinder, thereby cleaning the ignition tube. When it is necessary to disassemble, the tube body can be easily removed by lifting after the gas pipe is removed, making disassembly and assembly more convenient. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Combination Figures 1 to 4The burner head shown includes a furnace body 1 and a ignition tube 4. A combustion chamber 2 is provided inside the furnace body 1. A cylindrical mounting groove 3 is provided on one side of the combustion chamber 2 on the furnace body 1. A through hole is provided at the lower end of the cylindrical mounting groove 3 to penetrate the furnace body 1 and accommodate the ignition tube 4. The ignition tube 4 includes a tube body 8, and a mounting sleeve 7 is sleeved on the tube body 8. The mounting sleeve 7 and the tube body 8 are made of stainless steel. The mounting sleeve 7 is installed inside the furnace body 1. An exhaust nozzle 9 is detachably installed at one end of the tube body 8. A limiting part is provided on one side of the exhaust nozzle 9, which is mounted on the tube body 8. The tube body 8 is movably disposed inside the mounting sleeve 7 so that the limiting part and the exhaust nozzle 9 exit from the mounting sleeve 7. The tube 8 extends or retracts into the mounting cylinder 7, which is inserted into the mounting groove 3 of the cylinder body. Ignition needles 5 and sensing needles 6, corresponding to the gas nozzles 9, are respectively provided on both sides of the mounting groove 3. In this embodiment, by installing the mounting cylinder 7 inside the furnace body 1, the gas nozzles 9 of the tube body 8 are engaged in the mounting cylinder 7 by the limiting part when in use. When it is necessary to clean the ignition tube, simply lift the tube body 8 so that the limiting part and the gas nozzles 9 extend out of the mounting cylinder 7, thereby cleaning the ignition tube. When it is necessary to disassemble, the tube body 8 can be easily removed by lifting after the gas pipe is removed, making disassembly and assembly more convenient.

[0018] The limiting part of this embodiment includes a first limiting ring 12 and a second limiting ring 13. The first limiting ring 12 and the second limiting ring 13 are fixed on the tube body 8 in an up-down distribution. The lower end face of the air outlet nozzle 9 is in contact with the upper end face of the first limiting ring 12. The second limiting ring 13 can be snapped into the mounting cylinder 7. After the air outlet nozzle 9 is installed on the tube body 8, the first limiting ring 12 can prevent the air outlet nozzle 9 from exceeding the installation stroke during installation, thereby affecting the air outlet effect. The second limiting ring 13 can prevent the tube body 8 from penetrating and falling off from the lower end of the mounting cylinder 7 after the tube body 8 is retracted into the mounting cylinder 7. At the same time, it can limit the height position of the air outlet nozzle 9 during normal use.

[0019] In this embodiment, the outer walls of both the upper and lower ends of the pipe body 8 are provided with external thread sections 14. One end of the gas nozzle 9 is threaded onto the external thread section 14 at the upper end of the pipe body 8. The upper end face of the gas nozzle 9 is provided with a first gas outlet hole 10, and the circumferential direction of the gas nozzle 9 is provided with a second gas outlet hole 11. When the lower end face of the gas nozzle 9 is in contact with the upper end face of the first limiting ring 12, the upper end face of the pipe body 8 is lower than the second gas outlet hole 11. This allows the gas nozzle 9 to be detachably installed on the upper end of the pipe body 8 by means of a threaded connection. Under the limitation of the first limiting ring 12, after the gas nozzle 9 is threadedly installed, it is prevented from being blocked by the outer wall of the pipe body 8, thus affecting the flame size of the ignition source. In this embodiment, the external thread section 14 at the lower end of the pipe body 8 is used to thread a three-way metal pipe for connecting the gas pipe and the air pipe, so that the gas and air enter the pipe body 8 for premixing. When removing the pipe body 8, the three-way metal pipe can also be easily unscrewed.

[0020] The mounting cylinder 7 is hollow, with an opening 15 at the upper end and a bottom cover 16 at the lower end. The bottom cover 16 has a pipe hole 17 that can accommodate the pipe body 8. The outer diameter of the second limiting ring 13 is larger than the inner diameter of the pipe hole 17. This allows the pipe body 8 to pass through the interior of the mounting cylinder 7. At the same time, the second limiting ring 13 is used to hold the pipe body 8 in place on one side of the pipe hole 17, preventing the pipe body 8 from falling further and detaching, or causing the air nozzle 9 to penetrate deep into the interior of the mounting cylinder 7 and affect the ignition source.

[0021] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
