[0002] A gas stove is a kitchen appliance that uses gas such as natural gas or liquefied petroleum gas as fuel for cooking food. It usually consists of one or more gas burners, each of which has a control valve that can adjust the size of the flame. If the flame suddenly goes out or becomes abnormal, it is necessary to prevent gas leakage from causing a fire or explosion, so a stove protection device for infrared burners is needed.

[0003] During the use of the protection device for infrared burners in traditional stoves, when the gas stove is in the ignition state, after the gas flow is blocked by the electrode, the concentration of the gas is increased in the blocking area of ​​the electrode to form a reflux, so that the pulse electric sparks emitted by the discharge electrode ring can quickly ignite the gas in the reflux area, and at the same time, the ignition rate of the gas stove is greatly improved through multi-point discharge. After the dustproof sheet, discharge needle and flameout protection probe are designed as one, the central ventilation channel, ignition needle and flameout protection probe will not be exposed, which greatly improves the aesthetics of the stove, solves the unsafety of ignition under the infrared stove, and greatly improves the popularization effect of infrared stoves.

[0004] However, when using the protective device for infrared burners in traditional stoves, the flame size of the gas stove is adjusted only by adjusting the gas flow rate of the gas valve, which cannot improve the efficiency of gas use, resulting in a large amount of gas being wasted, affecting the combustion efficiency of the stove used for infrared burners.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a protective device for an infrared burner of a stove, comprising a stove 1, a transmitter 2 is fixedly connected inside the stove 1, a receiver 3 is fixedly connected inside the stove 1, a gas seat 4 is fixedly connected inside the stove 1, a fixing ring 6 is fixedly connected inside the gas seat 4, a slot 5 is provided inside the gas seat 4, a fixing plate 7 is fixedly connected inside the fixing ring 6, an opening 8 is provided inside the fixing plate 7, a limiting groove 9 is provided inside the fixing plate 7, a baffle 10 is rotatably connected to the top of the fixing plate 7, a limiting assembly is arranged on the outer wall of the baffle 10, a through hole 11 is provided inside the baffle 10, a paddle 13 is fixedly connected to the outer wall of the baffle 10, the outer wall of the paddle 13 is penetrated inside the slot 5, and the limiting assembly comprises a limiting ring 12, the limiting ring 12 is fixedly connected to the outer wall of the baffle 10, and the outer wall of the limiting ring 12 is slidably connected to the limiting groove 9;

[0032] Specifically, first of all, to adjust the combustion efficiency of gas, we do not need complex equipment or technology. Just gently turn the paddle 13 to drive the baffle 10 to rotate. This design cleverly uses the principle of mechanical transmission to make the operation simple and intuitive. The baffle 10 is limited in the limit groove 9 by the limit ring 12 to ensure the stability and accuracy of its rotation. When the baffle 10 rotates to different positions, the through hole 11 on it will align with the openings 8 of different shapes on the fixed plate 7. These openings 8 are carefully designed with different aperture sizes, so that the atomization effect of the gas can be adjusted when it is sprayed. The adjustment of the atomization effect has an important influence on the combustion efficiency of gas. By changing the atomization degree of the gas spray, the mixing degree of the gas and the air can be affected, and then the combustion state of the flame can be adjusted. The appropriate atomization effect can fully mix the gas and the air, improve the combustion efficiency of the flame, and reduce the generation of unburned gas and harmful gases. The design is also equipped with a combination of a transmitter 2 and a receiver 3. This combination can detect the flame state of the gas stove in real time. Transmitter 2 emits infrared rays, and when there is a flame, the infrared rays will be reflected by the flame and return to receiver 3. Once the flame is extinguished, the infrared rays cannot return to receiver 3, thereby triggering the safety mechanism to remind the user to deal with it in time to avoid safety hazards such as gas leakage.

[0033] Reference Figure 1 and Figure 3A connecting pipe 14 is fixedly connected to the gas seat 4, a cavity 15 is opened inside the connecting pipe 14, a gas pipe 21 is arranged on one side of the connecting pipe 14, a card slot 22 is opened inside the gas pipe 21, a release sleeve 16 is slidably connected to the outer wall of the connecting pipe 14, a fixing ring 17 is fixedly connected inside the release sleeve 16, a spring 18 is sleeved on the outer wall of the connecting pipe 14, one end of the spring 18 is fixedly connected to the inside of the connecting pipe 14, and the other end of the spring 18 is fixedly connected to one side of the fixing ring 17, a ball 19 is arranged inside the connecting pipe 14, the outer wall of the ball 19 is slidably connected to the inside of the cavity 15, the outer wall of the ball 19 is embedded in the card slot 22, a sealing ring 20 is fixedly connected to the inside of the connecting pipe 14, and the inner wall of the sealing ring 20 is attached to the outer wall of the gas pipe 21;

[0034] Specifically, when the gas pipe 21 needs to be connected to the gas socket 4, first, the release sleeve 16 is moved to the left. This action will drive the fixing ring 2 17 to separate from the cavity 15, creating conditions for the movement of the ball 19. In this process, although the ball 19 can move freely in the cavity 15, it will not fall out due to the action of certain mechanisms. Next, the gas pipe 21 is directly inserted into the interior of the connecting pipe 14. After the gas pipe 21 is inserted, the release sleeve 16 is released. At this time, the tension of the spring 18 begins to play a role, and it drives the release sleeve 16 to reset by pushing the fixing ring 2 17. This reset process is very important because it ensures that the ball 19 can be embedded in the slot 22, thereby locking the gas pipe 21. Finally, when the ball 19 is embedded in the slot 22, a stable connection is formed between the gas pipe 21 and the connecting pipe 14. The sealing ring 20 can effectively prevent gas leakage.

[0035] Working principle: When the stove is used as a protective device for an infrared burner, the gas pipe 21 needs to be connected to the gas seat 4. The release sleeve 16 is first moved to the left, and then the release sleeve 16 drives the second fixing ring 17 to separate from the cavity 15, so that the ball 19 can move, but the ball 19 will not fall when moving in the cavity 15. Then the gas pipe 21 is directly inserted into the connecting pipe 14, and then the release sleeve 16 is released. Under the tension of the spring 18, the release sleeve 16 will be pushed to push the second fixing ring 17 to drive the release sleeve 16 to reset. The release sleeve 16 drives the second fixing ring 17 to block the cavity 15, so that the ball 19 is embedded in the slot 22 to lock the gas pipe 21. The gas pipe 21 and the connecting pipe 14 are sealed by a sealing ring 20. When the combustion efficiency of the gas needs to be adjusted, the baffle 10 only needs to be rotated by turning the paddle 13. The baffle 10 is limited in the limiting groove 9 by the limiting ring 12, thereby driving the through hole 11 on the baffle 10 to align with the openings 8 of different shapes on the fixing plate 7. The openings 8 are set with different aperture sizes to adjust the atomization effect when the gas is sprayed, thereby improving the combustion efficiency of the gas. Subsequently, when the gas stove is accidentally extinguished, it can be detected by the cooperation of the transmitter 2 and the receiver 3. The transmitter 2 can emit infrared rays and return to be detected by the receiver 3, so that the user can be alerted when the flame is extinguished.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
