Description

Technical Field

[0001] This utility model relates to a burner for a gas stove, and more particularly to a burner that is easy to maintain. Background Technology

[0002] The burner is an important component of a gas stove (also known as the gas stove burner head). Its function is to mix gas and air in a certain proportion and ignite them at the outlet to form a stable and efficient flame, providing heat for cooking.

[0003] In existing technologies, such as the detachable gas stove burner head disclosed in CN222103678U, a furnace shell is included. Inside the furnace shell, from top to bottom, a flame-gathering cover, a ignition cover, and a ignition seat are arranged sequentially. The ignition seat abuts against the inner wall of the furnace shell. An ignition component is installed on the ignition seat. The ignition cover is placed on the ignition seat and has an ignition chamber for accommodating the ignition component. The flame-gathering cover is placed on the furnace shell, and its bottom abuts against the ignition cover. A gap is formed between the ignition seat and the bottom wall of the furnace shell. The gas stove burner has a gas chamber, and a gas guide chamber is formed between the side wall of the stove shell and the side wall of the flame cover and the ignition cover. A combustion chamber is formed inside the flame cover. The ignition base has a first through hole for connecting the gas chamber and the gas guide chamber, and the flame cover has a second through hole for connecting the gas guide chamber and the combustion chamber. The ignition chamber is connected to the combustion chamber. This detachable gas stove burner has the advantages of low maintenance cost and good combustion effect. It can avoid direct contact between the ignition component and soup, and extend the service life of the ignition component.

[0004] However, it still has some shortcomings. For example, the ignition seat is in contact with the inner wall of the furnace shell. Although the bottom of the flame cover is in contact with the ignition cover installed on the ignition seat, the stability of the ignition seat in the furnace shell cannot be guaranteed. As a result, when it is in use, it is easy for the ignition seat, along with the ignition cover and the flame cover, to be detached from the inside of the furnace shell due to the impact of the gas. In this case, the reliability of the burner cannot be guaranteed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a burner that is easy to maintain and can guarantee reliability.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a burner that is easy to maintain, including an air inlet pipe at the bottom and an installation cylinder with an opening at the top. The installation cylinder is provided with a detachable flame tube, a ignition cap and a ignition seat from top to bottom. The bottom of the flame tube abuts against the top of the ignition cap. A fixing ring is fixedly provided at the top of the flame tube. A pressure block is detachably provided at the top of the installation cylinder. The pressure block has a first through hole for the top of the flame tube to pass through. The bottom of the pressure block abuts against the top of the fixing ring.

[0007] A further preferred embodiment of this utility model is that a high-temperature resistant, non-stick coating is provided on the contact surface between the tinder holder and the tinder cover, and on the contact surface between the tinder cover and the fire-gathering tube.

[0008] A further preferred embodiment of this utility model is as follows: the outer wall of the top of the tinder cover is provided with an external thread, and the inner wall of the bottom of the fire-gathering tube is provided with an internal thread that engages with the external thread, and the fire-gathering tube is screwed to the tinder cover.

[0009] A further preferred embodiment of this utility model is as follows: the tinder holder is provided with a connecting seat that connects to the tinder cover, and the outer wall of the connecting seat is provided with a plurality of T-shaped connecting blocks arranged circumferentially. The inner wall of the bottom of the fire-gathering tube is provided with a plurality of connecting grooves that match the connecting blocks, and the connecting grooves are interference-fitted with the connecting blocks.

[0010] A further preferred embodiment of this utility model is: a clamping ring for pressing the fixing ring is provided around the bottom of the pressure block around the first through hole.

[0011] A further preferred embodiment of this utility model is that the mounting cylinder and the pressure block are detachably connected by bolts.

[0012] A further preferred embodiment of this utility model is: a protective cover is provided on the top of the fire-gathering tube, and the protective cover has multiple second through holes.

[0013] Compared with the prior art, the advantages of this utility model are that when the pressure block is installed on the top of the mounting cylinder, the top of the flame-gathering tube protrudes through the first through hole, and at the same time, the bottom of the pressure block presses against the top of the fixing ring. Then, the pressure block is detachably connected to the top of the mounting cylinder by bolts. This ensures the stability of the ignition seat, ignition cover, and flame-gathering tube in the middle. As a result, when the burner is in use, it avoids the problem of the ignition seat 7, along with the ignition cover and flame-gathering tube, being detached from the inside of the mounting cylinder due to the impact of the combustion gas. This ensures the reliability of the burner. When maintaining the burner, first remove the pressure block from the top of the mounting cylinder, and then take out the flame-gathering tube, ignition cover, and ignition seat from the mounting cylinder in sequence. This ensures that the burner is easy to maintain and also ensures the reliability of the burner during use. Attached Figure Description

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0025] This embodiment mainly describes the structure of a burner that is easy to maintain, as follows:

[0026] like Figures 1-7As shown, a burner that is easy to maintain includes an air inlet pipe 2 (composed of a gas pipe 21 for supplying gas and an air pipe 22 for supplying air) at the bottom and an installation cylinder 1 with an open top. A flaming tube 5, a ignition cap 6, and an ignition base 7 (with an ignition assembly 9 for igniting gas) are detachably arranged sequentially from top to bottom within the installation cylinder 1. The bottom of the flaming tube 5 abuts against the top of the ignition cap 6, and a retaining ring 51 is fixedly installed at the top of the flaming tube 5. A pressure block 4 is detachably installed at the top of the installation cylinder 1, and a first through hole 41 is provided on the pressure block 4 for the top of the flaming tube 5 to pass through. The bottom of the pressure block 4 abuts against the top of the retaining ring 51, thus, when the pressure block 4 is installed on the top of the installation cylinder 1... When the burner is in use, the top of the ignition tube 5 protrudes through the first through hole 41, while the bottom of the pressure block 4 presses against the top of the fixing ring 51. Then, the pressure block 4 is detachably connected to the top of the mounting cylinder 1 by bolts. This ensures the stability of the ignition seat 7, ignition cover 6, and ignition tube 5 in the mounting cylinder 1. This prevents the ignition seat 7, along with the ignition cover 6 and ignition tube 5, from detaching from the mounting cylinder 1 due to the impact of the combustion gas during use. This ensures the reliability of the burner. When maintaining the burner, first remove the pressure block 4 from the top of the mounting cylinder 1, and then remove the ignition tube 5, ignition cover 6, and ignition seat 7 from the mounting cylinder 1 in sequence. This ensures that the burner is easy to maintain and reliable during use.

[0027] Furthermore, to facilitate the disassembly of the burner after use, a high-temperature resistant anti-stick coating (such as a solid lubricating coating of molybdenum disulfide) is provided on the contact surfaces of the ignition base 7 and the ignition cover 6, and on the contact surfaces of the ignition cover 6 and the ignition tube 5. This reduces the problem of sintering and sticking of components due to high temperatures during long-term use of the burner, thus facilitating the disassembly of the used burner.

[0028] Furthermore, to facilitate the removal of the tinder cover 6 from the mounting cylinder 1, the outer wall of the top of the tinder cover 6 is provided with an external thread, and the inner wall of the bottom of the fire-collecting cylinder 5 is provided with an internal thread that engages with the external thread. The fire-collecting cylinder 5 is screwed to the tinder cover 6, so that when the fire-collecting cylinder 5 is removed from the mounting cylinder 1, the tinder cover 6 can be removed together, thus facilitating the removal of the tinder cover 6 from the mounting cylinder 1.

[0029] Furthermore, to facilitate the removal of the tinder holder 7 from the mounting cylinder 1, a connecting seat 8 is provided on the tinder holder 7 to connect with the tinder cover 6. At the same time, multiple T-shaped connecting blocks 81 are arranged circumferentially on the outer wall of the connecting seat 8, and multiple connecting grooves 61 matching the connecting blocks 81 are opened on the inner wall of the bottom of the tinder tube 5. The connecting grooves 61 and the connecting blocks 81 are interference-fitted. In this way, when the tinder cover 6 is removed from the mounting cylinder 1, the tinder holder 7 can also be removed together, which makes it convenient to remove the tinder holder 7 from the mounting cylinder 1.

[0030] In order to improve the clamping effect of the pressure block 4 on the fixing ring 51, a clamping ring 42 for clamping the fixing ring 51 is provided around the first through hole 41 at the bottom of the pressure block 4.

[0031] To prevent foreign objects from entering the burner from the top of the fire collection tube 5 during use, a protective cover 3 is installed on the top of the fire collection tube 5. At the same time, to ensure the combustion of the flame, multiple second through holes are provided on the protective cover 3.
