Description

Technical Field

[0001] This utility model belongs to the field of burner technology, and in particular relates to a burner with liquid storage function. Background Technology

[0002] Burners are kitchen appliances needed for cooking in daily life. Existing burners have the following defects: when cooking with a pointed-bottom pan, overflowing liquid tends to accumulate at the bottom of the pan, dripping onto the center burner cap and flowing down into the flame outlet, causing blockage and leading to problems such as accidental flameout and poor ignition.

[0003] Existing patent document (publication number: CN222068508U) discloses "a gas burner", which also has the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and provide a burner with liquid storage function. The structure is novel. The support plate provides radial support to the central ejector tube, reducing the impact of thermal expansion and contraction on the central ejector tube and improving its stability. The liquid tray can not only collect liquid droplets dripping from the bottom of the pot, but also block liquid droplets from the flame outlet of the central burner cap, preventing the liquid droplets from entering the flame outlet and causing blockage.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A burner with liquid storage function includes:

[0007] Ignition needle and thermocouple;

[0008] The flame cap assembly includes a central flame cap and an outer ring flame cap.

[0009] The burner head assembly includes a base, a central ejector tube, and an outer ring ejector tube, with the central ejector tube and the outer ring ejector tube respectively located on the base;

[0010] Its features are:

[0011] A support plate is provided on the bottom surface of the outer ring burner cap, and a positioning slot corresponding to the central injector tube is opened on the support plate. A liquid collection tray is connected to the top of the central burner cap, and the flame outlet of the central burner cap is located below the projection of the liquid collection tray. This burner has a novel structure. The support plate provides radial support to the central injector tube, reducing the impact of thermal expansion and contraction on the central injector tube and improving its stability. The liquid collection tray can not only collect droplets dripping from the bottom of the pot, but also block droplets from entering the flame outlet of the central burner cap and causing blockage.

[0012] Furthermore, a reinforcing plate is provided on the inner bottom surface of the base. The reinforcing plate has a limiting slot corresponding to the outer ring ejector tube. The reinforcing plate provides radial support to the outer ring ejector tube, reduces the impact of thermal expansion and contraction on the outer ring ejector tube, and improves its stability.

[0013] Furthermore, the reinforcing plate has an L-shaped section, on which a corresponding limiting sleeve for the thermocouple is installed. The limiting sleeve provides radial restraint for the thermocouple, keeping it vertical and preventing it from wobbling. This avoids poor thermocouple contact that could lead to inaccurate temperature sensing, affecting the judgment of the flame state and even causing safety hazards.

[0014] Furthermore, the reinforcing plate is riveted to the base. This riveting method provides high connection strength and excellent high-temperature resistance, enabling it to withstand the high-temperature conditions of the burner's operating environment.

[0015] Furthermore, the positioning bayonet is provided with an extension that contacts the central ejector tube, which increases the contact area between the positioning bayonet and the central ejector tube, thereby improving the supporting effect of the support plate on the central ejector tube.

[0016] Furthermore, the liquid collection tray is welded to the top of the central flame cap. This integrated design ensures a secure and reliable seal, preventing the tray from easily being lost.

[0017] Furthermore, the bottom of the liquid collection tray is provided with a protrusion, and the top of the center flame cap is provided with a positioning recess corresponding to the protrusion, so as to realize the positioning of the liquid collection tray on the center flame cap. The positioning is easy, and the liquid collection tray can be cleaned and replaced separately, reducing maintenance costs.

[0018] Furthermore, the support plate is provided with limiting through holes corresponding to the ignition needle and thermocouple. These holes provide radial limiting for the ignition needle and thermocouple, preventing swaying and improving stability.

[0019] Furthermore, a support base is provided between the central ejector tube and the outer ring ejector tube, and the support base has fixing holes. Screws are inserted into the fixing holes to fix the support base to the bottom shell of the stove, which improves the convenience of installation. The support base restrains the central ejector tube and the outer ring ejector tube together, preventing shaking and improving stability.

[0020] Furthermore, the support plate is riveted to the outer ring burner cap. This riveting method provides high connection strength and excellent high-temperature resistance, enabling it to withstand the high-temperature conditions of the burner's operating environment.

[0021] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0022] 1. The support plate provides radial support to the central ejector tube, reducing the impact of thermal expansion and contraction on the central ejector tube and improving its stability; the support plate also provides radial restraint for the ignition needle and thermocouple, preventing swaying and improving stability.

[0023] 2. The reinforcing plate provides radial support to the outer ring ejector tube, reducing the impact of thermal expansion and contraction on the outer ring ejector tube and improving its stability; the limiting sleeve provides radial limiting for the thermocouple, keeping the thermocouple in a vertical position and preventing it from shaking, thus avoiding inaccurate temperature sensing due to poor thermocouple contact, which could affect the judgment of the flame status and even cause safety hazards.

[0024] 3. The liquid collection tray can collect liquid droplets that drip from the bottom of the pot, making cleaning easy. The liquid collection tray also blocks liquid droplets from entering the flame outlet and causing blockage.

[0025] 4. There are two ways to connect the liquid collection tray and the center burner cap: ① The center burner cap and the liquid collection tray are welded and fixed together as one piece, which is firm and reliable and the liquid collection tray is not easy to lose; ② The liquid collection tray and the center burner cap can be detached and separated. The protrusion is embedded into the positioning recess to realize the quick positioning of the liquid collection tray on the center burner cap. The positioning difficulty is low and the operation is simple. The liquid collection tray can be cleaned and replaced separately, which reduces maintenance costs. Attached Figure Description

The central ejector tube 4 and the outer ring ejector tube 5 are respectively disposed on the base 3. The central ejector tube 4 is connected to the central burner cap 1, and the outer ring ejector tube 5 is connected to the outer ring burner cap 2. A support seat 6 is provided between the central ejector tube 4 and the outer ring ejector tube 5, and a fixing hole 7 is provided on the support seat 6.

[0038] Screws are inserted into the fixing hole 7 to fix the support base 6 to the bottom shell of the stove, which improves the convenience of installation. The central ejector tube 4 and the outer ring ejector tube 5 of the support base 6 are restrained together to prevent shaking and improve stability.

[0039] A support plate 8 is riveted to the bottom surface of the outer ring burner cover 2. The support plate 8 is U-shaped and is located between the outer ring burner cover 2 and the base 3. It is riveted, which has high connection strength and excellent high temperature resistance, and can adapt to the high temperature conditions in the burner working environment.
