Description

Technical Field

[0001] This utility model relates to the field of cooking stove burner technology, specifically a fully premixed gas cooking stove burner for Chinese cuisine. Background Technology

[0002] The thermal efficiency of a burner, which uses fuels such as natural gas or oil, depends critically on the mixing ratio of the gas and air. To fully utilize the fuel, it must be completely combusted. Currently, most burners employ advanced premixing technology, where the gas and air are mixed twice in the burner's mixing chamber before being injected and burned from the burner surface.

[0003] In the prior art, an energy-saving and environmentally friendly burner head (CN221197407U) involves placing an energy-concentrating plate on top of the burner head, aligning several mounting holes on the plate with several vertical rods on the top of a fixed plate, and then pressing the plate downwards. This causes the plate to compress the limiting rods on the surface of the vertical rods, allowing the limiting rods to enter the movable groove. When the bottom of the energy-concentrating plate contacts the top of the fixed plate, the compressive force on the limiting rods disappears, and the limiting rods are reset by the elastic force of the spring, allowing them to move back to the outside of the movable groove. The limiting rods limit the movement of the energy-concentrating plate, preventing it from detaching from the burner head body. Furthermore, through the cooperation of the threaded rod and the threaded groove, the vertical rod and the threaded rod move downwards, causing the limiting rods on the surface of the vertical rods to move synchronously with the vertical rods and contact the top of the energy-concentrating plate. The limiting rods compress and fix the energy-concentrating plate, preventing it from jumping up and down, thus further improving its stability. However, in the existing technology, in order to prevent the energy-concentrating plate from jumping up and down, it is necessary to tighten the threaded rod, which is quite troublesome and has poor practicality. Therefore, those skilled in the art have proposed a fully premixed burner for Chinese-style gas cooking stoves to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a fully premixed burner for a Chinese-style gas-fired wok, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A premixed gas stove burner for Chinese cooking includes a burner body. Multiple annularly spaced pads are installed on the inner wall of the burner body. An energy-concentrating plate is placed on each pad. Multiple annularly spaced positioning grooves are formed on the energy-concentrating plate. Positioning rods that mate with the positioning grooves are installed on the pads. Locking mechanisms are provided on both sides of the positioning rods away from the pads to fix the energy-concentrating plate to the pads. An elastic mechanism is provided inside the positioning rods and connected to the locking mechanisms to provide elastic force to the locking mechanisms.

[0007] As a further embodiment of this utility model: the positioning mechanism includes sliding cavities on both sides of the end of the positioning rod away from the pad, and a locking block is slidably disposed in the sliding cavity. The height of the sliding cavity from the pad is the same as the thickness of the energy-concentrating plate.

[0008] As a further improvement of this utility model: guide grooves are provided on both sides of the bottom of the positioning groove inside the energy-concentrating plate, and inclined grooves are provided on the card block.

[0009] As a further embodiment of this utility model: the elastic mechanism includes an inner cavity opened in the middle of the positioning rod and located between the slider and the pad, a sliding plate is slidably arranged in the inner cavity, both ends of the sliding plate are hinged to one end of a connecting rod, the other end of the connecting rod is hinged to the side wall of the locking block, and a spring connected to the sliding plate is provided at the end of the inner cavity near the pad.

[0010] As a further embodiment of this utility model: the burner body is provided with a frame, the frame is provided with a groove, the groove is placed with a fire cap, the outer wall of the fire cap is provided with multiple fire outlets distributed in a ring, and the burner body is provided with a gas outlet located in the middle of the frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the energy-concentrating plate and positioning rod are first aligned so that the positioning rod can be inserted into the positioning groove of the energy-concentrating plate, thereby completing the pre-positioning of the energy-concentrating plate. Then, the energy-concentrating plate is pressed, causing it to move along the positioning rod towards one side of the pad. During this process, the energy-concentrating plate will first squeeze the locking mechanism, causing the locking mechanism to retract without affecting the energy-concentrating plate's continued downward movement along the positioning rod. When the bottom of the energy-concentrating plate contacts the pad, the locking mechanism is no longer squeezed by the energy-concentrating plate, allowing it to be released and limiting the top of the energy-concentrating plate. Together with the pad, the top and bottom of the energy-concentrating plate can be limited, thus ensuring a stable connection between the energy-concentrating plate and the furnace head body. The entire process only requires placing the energy-concentrating plate into the positioning rod and pressing it down, without any other excessive operations. The structure is compact and easy to install. Attached Figure Description

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] Please see Figures 1-3 A premixed gas stove for Chinese cooking includes a stove body 1. Multiple annularly spaced pads 7 are installed on the inner wall of the stove body 1. An energy-concentrating plate 8 is placed on the pads 7. Multiple annularly spaced positioning grooves 9 are formed on the energy-concentrating plate 8. Positioning rods 11 that cooperate with the positioning grooves 9 are installed on the pads 7. A locking mechanism is provided on both sides of the end of the positioning rod 11 away from the pads 7 to fix the energy-concentrating plate 8 to the pads 7. An elastic mechanism is provided inside the positioning rod 11 and connected to the locking mechanism to provide elastic force to the locking mechanism.

[0018] In use, this utility model first aligns the energy-concentrating plate 8 and the positioning rod 11, allowing the positioning rod 11 to be inserted into the positioning groove 9 of the energy-concentrating plate 8, thus pre-positioning the energy-concentrating plate 8. Then, the energy-concentrating plate 8 is pressed, causing it to move along the positioning rod 11 towards the side of the pad 7. During this process, the energy-concentrating plate 8 first compresses the locking mechanism, causing it to retract without affecting the energy-concentrating plate 8's continued downward movement along the positioning rod 11. When the bottom of the energy-concentrating plate 8 contacts the pad 7, the locking mechanism is no longer compressed by the energy-concentrating plate 8, releasing it and limiting the top of the energy-concentrating plate 8. Together with the pad 7, the top and bottom of the energy-concentrating plate 8 can be limited, allowing the energy-concentrating plate 8 to be stably connected to the furnace head body 1. The entire process only requires placing the energy-concentrating plate 8 into the positioning rod 11 and pressing it down, without any other excessive operations. The structure is compact, easy to install, and more practical.

[0019] In one embodiment, the locking mechanism includes sliding cavities 12 on both sides of the end of the positioning rod 11 away from the pad 7. A locking block 13 is slidably disposed within the sliding cavity 12. The height of the sliding cavity 12 from the pad 7 is the same as the thickness of the energy-concentrating plate 8. The elastic mechanism includes an inner cavity 15 located in the middle of the positioning rod 11 and between the slider and the pad 7. A sliding plate 17 is slidably disposed within the inner cavity 15. Both ends of the sliding plate 17 are hinged to one end of a connecting rod 18, and the other end of the connecting rod 18 is hinged to the side wall of the locking block 13. A spring 16 connected to the sliding plate 17 is provided at the end of the inner cavity 15 near the pad 7. Guide grooves 10 are provided on both sides of the bottom of the positioning groove 9 within the energy-concentrating plate 8, and a sloping groove 14 is provided on the locking block 13.

[0020] In use, when the positioning groove 9 of the energy-concentrating plate 8 is connected to the positioning rod 11, pressing the energy-concentrating plate 8 causes it to descend along the positioning rod 11. The locking block 13 of the locking mechanism will contact the guide groove 10 first. Under the action of the guide groove 10, the locking block 13 will gradually be pressed into the sliding cavity 12. Simultaneously, under the action of the connecting rod 18, the sliding plate 17 slides down along the inner cavity 15 and compresses the spring 16. When the bottom of the energy-concentrating plate 8 contacts the pad 7, the bottom of the sliding cavity 12 is just flush with the top of the energy-concentrating plate 8. At this point, the locking block 13 is no longer subjected to pressure. Under the pressure of the spring 16, the slide plate 17 slides upward along the inner cavity 15. At the same time, driven by the connecting rod 18, the locking block 13 slides outward along the sliding cavity 12. Thus, the locking block 13 can limit the top of the energy-concentrating plate 8. With the help of the pad 7, the top and bottom of the energy-concentrating plate 8 can be limited, so that the energy-concentrating plate 8 can be stably connected to the furnace head body 1. The whole process only requires pressing the energy-concentrating plate 8 into the positioning rod 11. No other operations are required. The structure is spaced out, the installation is convenient, and the practicality is better.

[0021] In one embodiment, the burner body 1 has a frame 2 inside, a groove 4 inside the frame 2, and a burner cap 5 placed inside the groove 4. The outer wall of the burner cap 5 has multiple annularly distributed flame outlets 6. The burner body 1 has a gas outlet 3 located in the middle of the frame 2. The gas inlet is used to pour in gas, and the flame outlets 6 facilitate the generation of a small flame. An ignition device and a flameout device are also provided at the bottom of the burner, which will not be described in detail here.
