Description

Technical Field

[0001] This utility model relates to the field of stove head technology, specifically a stove head for a gas stove. Background Technology

[0002] The gas stove burner is the core combustion component of a gas stove, undertaking the key functions of gas delivery, air mixing, and stable combustion. It directly affects the gas stove's thermal efficiency, combustion stability, and safety. In terms of material selection, most mainstream burners use copper alloys or high-temperature resistant aluminum alloys. Copper alloys have good thermal conductivity and strong corrosion resistance, and can withstand high-temperature combustion environments for a long time without easily deforming. However, existing burners have certain defects.

[0003] For example, application number CN201621008804.7 describes a gas stove burner head, including a burner cap and an aluminum cap. The burner cap is mounted on the aluminum cap and has multiple evenly distributed flame hole segments. Each flame hole segment has several evenly distributed flame holes, with gaps between adjacent flame hole segments. The inner ring of the burner cap also has several evenly distributed slots. The aluminum cap has corresponding locking blocks. The burner cap is positioned with the aluminum cap by engaging with the slots and locking blocks. The evenly distributed flame hole segments do not affect the flame distribution, but leave gaps for mounting pot racks, preventing the pot racks from being burned. This ensures that the CO content in the flue gas meets the requirements and guarantees safety. The engagement of the slots in the burner cap and the locking blocks in the aluminum cap prevents the burner cap from rotating 360 degrees. The reduced number of openings in the burner cap reduces processing time. However, this burner head may deform due to high temperatures, and the parts are prone to corrosion and wear. Oil impurities can easily seep into the gaps, leading to gas leakage. The substrate of the liquid collection tray is prone to rust and damage, and oil accumulation is difficult to clean. Waste liquid accumulation can also affect the safe operation of the burner head.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose a gas stove burner. Utility Model Content

[0005] The purpose of this utility model is to provide a burner head for a gas stove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a burner head for a gas stove, comprising a flame distributor and a protective mechanism, wherein the protective mechanism is fixedly connected to the top of the flame distributor, and the protective mechanism includes a nickel-based alloy layer fixedly connected to the inner wall of the flame distributor, and a ceramic wear-resistant layer is fixedly connected to one side of the nickel-based alloy layer, and a stepped sealing groove is provided inside the flame distributor, wherein a flexible graphite sealing ring is fixedly connected to the inner wall of the stepped sealing groove.

[0007] Preferably, the flame distributor and the protective mechanism are characterized in that the top of the flame distributor is fixedly connected to the protective mechanism, and the protective mechanism includes a nickel-based alloy layer fixedly connected to the inner wall of the flame distributor, and a ceramic wear-resistant layer is fixedly connected to one side of the nickel-based alloy layer, and a stepped sealing groove is opened inside the flame distributor, and a flexible graphite sealing ring is fixedly connected to the inner wall of the stepped sealing groove.

[0008] Preferably, the scraping mechanism includes an anti-corrosion layer fixedly connected to the inner wall of the liquid collection tray, and a superhydrophobic nano-coating is fixedly connected to the outer surface of the anti-corrosion layer. A magnetic scraper is rotatably connected to the inner surface of the liquid collection tray, and a magnetic block is adsorbed on the outer surface of the liquid collection tray. A drain port is provided on one side of the liquid collection tray.

[0009] Preferably, a large flame cap is fixedly connected to the top of the flame distributor, and a small flame cap is fixedly connected to the top of the large flame cap.

[0010] Preferably, the top of the liquid-holding tray is fixedly connected to a support foot, and the bottom of the liquid-holding tray is provided with a base.

[0011] Preferably, the inner surface of the base is provided with a slot, and an arc-shaped heat-concentrating plate is engaged with the inner surface of the slot.

[0012] Preferably, a heat-insulating asbestos layer is fixedly connected to one side of the arc-shaped heat-concentrating plate, and a pot support is fixedly connected to the top of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a protective mechanism, prevents the substrate of the burner from deforming due to high temperature due to the nickel-based alloy layer. Its excellent corrosion resistance can resist the erosion of corrosive substances produced by gas combustion, preventing rust and perforation of the inner wall of the burner. The ceramic wear-resistant layer further strengthens the inner wall of the burner, reduces the scouring and wear when the gas flows at high speed, and ensures stable gas delivery. The stepped sealing groove is precisely adapted to the flexible graphite sealing ring. When the burner is assembled with the large burner cap, the flexible graphite sealing ring is deformed by compression, which can fully fill the gap between the two. It can not only prevent oil and soup from overflowing during cooking from entering the gap, preventing internal components from failing due to oil accumulation, but also prevent dust and other impurities from seeping in, reducing component wear, helping to improve gas sealing, reducing the risk of gas leakage, ensuring safe use, extending the service life of the burner, improving the safety and reliability of the gas stove during use, and reducing maintenance frequency and cost. 2. This utility model, through the design of a scraping mechanism, constructs a cleaning and protection system for the gas stove burner. It provides key support for efficient burner operation from three dimensions: extending component lifespan, improving ease of use, and ensuring safe burner operation. The anti-corrosion layer prevents the substrate from rusting or breaking due to long-term contact with corrosive substances, maintaining the structural integrity of the drip tray. The superhydrophobic nano-coating, with its extremely low surface energy, significantly reduces the amount of oil adhering to the inner wall of the drip tray, lowering the probability of long-term oil accumulation forming stubborn stains. The magnetic scraper and the magnetic blocks on the outer surface of the drip tray form a magnetic linkage structure, allowing operation without disassembly. The scraped waste liquid can be directly discharged through the drain port, preventing waste liquid from accumulating in the drip tray and significantly saving users' cleaning time. It is especially suitable for high-frequency daily use scenarios, indirectly ensuring the safe operation of the burner. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-3As shown, a gas stove burner head includes a protective mechanism 2 fixedly connected to the top of a burner 1. The protective mechanism 2 includes a nickel-based alloy layer 201 fixedly connected to the inner wall of the burner 1, and a ceramic wear-resistant layer 202 fixedly connected to one side of the nickel-based alloy layer 201. A stepped sealing groove 203 is provided inside the burner 1, and a flexible graphite sealing ring 204 is fixedly connected to the inner wall of the stepped sealing groove 203. The nickel-based alloy layer 201 fits into the inner wall of the burner 1, resisting the high temperature of combustion and gas corrosion due to its excellent high temperature resistance and corrosion resistance. The ceramic wear-resistant layer 202 enhances the wear resistance of the inner wall, reducing gas scouring and friction damage from impurities. The stepped sealing groove 203 is adapted to the flexible graphite sealing ring 204. The flexible graphite sealing ring 204 deforms under pressure to fill the gaps, making the connection between the burner 1 and the large burner cap 5 tighter, preventing liquid and dust from entering the gaps, forming all-round protection against corrosion, wear, and leakage, and extending the service life of the burner head.

[0018] like Figure 4 As shown, a liquid collection tray 3 is provided at the bottom of the distributor 1, and a scraping mechanism 4 is provided inside the liquid collection tray 3. The scraping mechanism 4 includes an anti-corrosion layer 401 fixedly connected to the inner wall of the liquid collection tray 3, and a superhydrophobic nano-coating 402 fixedly connected to the outer surface of the anti-corrosion layer 401. A magnetic scraper 403 is rotatably connected to the inner surface of the liquid collection tray 3, and a magnetic block 404 is adsorbed on the outer surface of the liquid collection tray 3. A drain port 405 is provided on one side of the liquid collection tray 3. The anti-corrosion layer 401 adheres to the inner wall of the liquid collection tray 3 to isolate oil and soup corrosion and prevent the substrate from rusting and being damaged. The superhydrophobic nano-coating 402 reduces oil adhesion and lays the foundation for cleaning. The magnetic scraper 403 and the magnetic block 404 on the outer surface are magnetically linked. Pushing the magnetic block 404 can drive the magnetic scraper 403 to rotate and scrape off residual oil. The scraped waste liquid is quickly discharged through the drain port 405. All components work together to achieve anti-corrosion and easy cleaning functions.

[0019] Furthermore, a large flame cap 5 is fixedly connected to the top of the burner 1, and a small flame cap 6 is fixedly connected to the top of the large flame cap 5. A support foot 7 is fixedly connected to the top of the liquid collection tray 3, and a base 8 is provided at the bottom of the liquid collection tray 3. The large flame cap 5 and the small flame cap 6 on the top of the burner 1 provide high flame and low flame respectively to meet different cooking needs. The support foot 7 on the top of the liquid collection tray 3 firmly supports the burner 1, keeping the two at a reasonable distance. This does not affect the heat dissipation and combustion of the burner 1, and can quickly collect the oil and soup flowing from the surface of the burner 1, avoiding contamination of the stove body.

[0020] Furthermore, the inner surface of the base 8 is provided with a slot 9, and an arc-shaped heat-concentrating plate 10 is engaged with the inner surface of the slot 9. A heat-insulating asbestos layer 11 is fixedly connected to one side of the arc-shaped heat-concentrating plate 10, and a pot support 13 is fixedly connected to the top of the base 8. In windy conditions, the arc-shaped heat-concentrating plate 10 is installed, and the slot 9 on the inner surface of the base 8 precisely engages with the arc-shaped heat-concentrating plate 10. When not needed, the arc-shaped heat-concentrating plate 10 can be removed. Its arc-shaped structure can block external airflow from interfering with the flame. At the same time, it works in conjunction with the heat-insulating asbestos layer 11 to concentrate combustion heat, reduce heat loss, and improve thermal efficiency. The pot support 13 on the top of the base 8 stably supports the pot and ensures cooking efficiency.

[0021] Working principle: When using the burner of this gas stove, the base 8 serves as the basic support, and the pot support 13 is used to stably place the pot. In a windy environment, the groove 9 on the inner surface precisely engages with the arc-shaped heat-concentrating plate 10, which can block airflow interference. The heat-insulating asbestos layer 11 on one side of the arc-shaped heat-concentrating plate 10 insulates heat. Then, during ignition, the gas is distributed by the burner 1 and sprayed out from the flame holes of the large burner cap 5 and the small burner cap 6 respectively. After mixing with air, it is ignited. The nickel-based alloy layer 201 and the ceramic wear-resistant layer 202 of the protective mechanism 2 protect the burner 1 from... Due to high temperature and gas corrosion, the flexible graphite sealing ring 204 prevents gas leakage, the arc-shaped heat-concentrating plate 10 gathers heat to improve thermal efficiency, the heat-insulating asbestos layer 11 blocks heat transfer, and the pot support 13 stably supports the pot to ensure that the bottom of the pot is heated evenly. Finally, when cleaning after turning off the fire, after the burner head cools down, the magnetic block 404 of the outer surface scraping mechanism 4 of the liquid tray 3 is moved, which drives the internal magnetic scraper 403 to scrape off the liquid and oil on the surface of the superhydrophobic nano coating 402. The oil is discharged through the drain port 405. This is the working principle of the burner head of the gas stove.
