[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-8 An energy-saving block for a stove comprises an energy-saving block body 1, a gas stove body 2 arranged at the bottom of the energy-saving block body 1, and a placement component 3 arranged inside the gas stove body 2, wherein an adjustment structure 4 for reciprocatingly adjusting the energy-saving block body 1 up and down is arranged inside the gas stove body 2, and a driving mechanism 5 for driving the adjustment structure 4 is arranged inside the gas stove body 2. The placement component 3 comprises a support ring 301, a placement groove 302, and a connection ear 303.

[0034] The placement groove 302 is opened inside the support ring 301, and there are four connecting ears 303. The four connecting ears 303 are distributed in a ring shape outside the support ring 301. The support ring 301 is detachably connected to the inside of the gas stove body 2 through the connecting ears 303.

[0035] Specifically, there are a plurality of energy-saving block bodies 1 , which are distributed in a ring shape inside the placement groove 302 and extend to the upper surface of the gas stove body 2 .

[0036] It should be noted that the main component of the energy-saving block body 1 is aluminum silicate (the content of Al2O3·SiO2 is more than 90%), and the silica sol accounts for about 0.5%, which is also a high-temperature resistant material that is non-toxic and pollution-free. The main component is resistant to high temperatures of 1260-1450°C, which is better than many high-temperature resistant materials on the market. At the same time, the processing steps of the energy-saving block body 1 are to stir and fully blend the aluminum silicate powder and the silica sol, and then the mold is shaped and dried in the oven, and then placed in a high-temperature furnace and heated to more than 1000°C for calcination. By setting the energy-saving block body 1, the firepower control is more flexible and can meet different cooking needs. Whether it is stir-frying, stewing or making soup, you can find the most suitable firepower size, thereby improving the cooking experience. In summary, the slight adjustment of the up and down reciprocating angle of the energy-saving block body 1 of the gas stove during use has multiple advantages such as optimizing firepower distribution, improving thermal efficiency, saving gas, extending service life and improving cooking experience. These advantages make the gas stove more efficient, energy-saving and easy to maintain during use.

[0037] By providing the support ring 301 and the placement groove 302, it is convenient to adjust the angle of the energy-saving block body 1, and the mixing ratio of gas and air can be better controlled, so as to achieve more complete combustion, ensure that good energy-saving effects can be exerted on different types of stoves, and optimize the combustion process to reduce gas waste and achieve the purpose of saving gas. By reducing heat loss and optimizing the combustion process, the energy-saving block significantly improves the energy utilization efficiency of the stove. The improved combustion efficiency of the energy-saving block body 1 directly reduces energy consumption, thereby reducing energy costs. By placing the component 3 and using the energy-saving block body 1 in coordination, the gas is burned more completely, the harmful emissions generated by incomplete combustion are reduced, and it is more environmentally friendly. The optimized combustion process can heat food faster and improve cooking efficiency. The energy-saving block body 1 is designed to be easy to install and maintain, which is convenient for users to replace or clean by themselves.

[0038] Figures 4 to 6 In this embodiment, the adjustment structure 4 includes a mounting plate 401 fixedly connected to the inner wall of the gas stove body 2, an adjustment ring 402 arranged on the upper surface of the mounting plate 401, a guide rod 404 fixedly connected to the bottom of the adjustment ring 402, and an abutment wheel 405 rotatably connected to the bottom end of the guide rod 404.

[0039] Among them, a return spring 403 is fixedly connected between the mounting plate 401 and the adjustment ring 402, and a movable hole adapted to the guide rod 404 is opened inside the mounting plate 401. The return spring 403 is connected to the outside of the guide rod 404, and the guide rod 404 is slidably connected to the inside of the mounting plate 401.

[0040] Specifically, the adjustment ring 402 is a ring-shaped disc, the outer diameter of the support ring 301 is smaller than the inner diameter of the adjustment ring 402 , and the adjustment ring 402 is slidably connected to the outside of the support ring 301 .

[0041] It should be noted that the number of the return spring 403 , the guide rod 404 and the abutment wheel 405 are all four. The four abutment wheels 405 are distributed in a ring shape on the lower surface of the mounting plate 401 and rollably abut against the upper surface of the adjustment block 505 .

[0042] When this example is in use, the movement of the abutment wheel 405 and the guide rod 404 causes the adjustment ring 402 and the return spring 403 to reciprocate up and down. Under the elastic force of the return spring 403, the adjustment ring 402 slightly adjusts the angle of the energy-saving block body 1, which helps to accurately control the firepower according to different cooking needs and adapt to different cooking methods. At the same time, sufficient combustion can reduce the emission of harmful gases such as carbon monoxide, thereby achieving the advantage of high energy utilization efficiency.

[0043] Figure 5 and Figure 7 In this embodiment, the driving mechanism 5 includes a speed regulating motor 501 fixedly mounted on the inner bottom wall of the gas stove body 2, a transmission gear 502 fixedly connected to the output shaft of the speed regulating motor 501, a limit rod 504 fixedly connected to the inner bottom wall of the gas stove body 2, an adjustment gear ring 503 rotatably connected to the inside of the gas stove body 2, and an adjustment block 505 arranged on the upper surface of the adjustment gear ring 503. Driven by the driving mechanism 5, the slight adjustment of the up and down reciprocating angle of the energy-saving block body 1 during use has multiple advantages such as optimizing firepower distribution, improving thermal efficiency, saving gas, extending service life, and improving cooking experience. By adjusting the angle of the energy-saving block body 1, the contact area between the flame and the bottom of the pot can be adjusted, so that the firepower is more evenly distributed on the bottom of the pot. This uniform heating helps to improve cooking efficiency, ensure that the food is heated evenly, and avoid local overheating or no heating. The contact area and angle between the flame and the bottom of the pot have a great influence on thermal efficiency. Adjusting the angle of the energy-saving block body 1 can make the flame closer to the bottom of the pot, thereby making full use of the outer flame part of the flame for heating. The outer flame has the highest temperature, so it can transfer heat energy to the food more effectively, improving thermal efficiency. Because the flame is in closer contact with the bottom of the pot, the heat energy transfer is more efficient, so the amount of gas used can be reduced while ensuring the cooking quality. This helps reduce cooking costs and is also more environmentally friendly.

[0044] Among them, the transmission gear 502 is meshed with the adjusting gear ring 503, the adjusting gear ring 503 is rotatably connected to the upper surface of the limiting rod 504, and a limiting groove matched with the limiting rod 504 is opened inside the adjusting gear ring 503, and the limiting rod 504 and the limiting groove are slidably connected.

[0045] Specifically, there are four limiting rods 504 , which are distributed in a ring shape on the lower surface of the adjusting gear ring 503 , and there are four adjusting blocks 505 .

[0046] When this embodiment is in use, the controller starts the speed regulating motor 501 to drive the transmission gear 502 to rotate, so that the transmission gear 502 engages to drive the adjustment ring gear 503 to transmit, thereby driving the adjustment block 505 to perform continuous circular motion, so that the adjustment block 505 drives the adjustment ring 402 to reciprocate up and down through the abutment wheel 405 and the guide rod 404, so that the reciprocating angle of the energy-saving block body 1 is adjusted through the adjustment structure 4, and the contact area between the flame and the bottom of the pot can be adjusted, so that the firepower is more evenly distributed on the bottom of the pot.

[0047] Figure 7 and 8 In this embodiment, a telescopic mechanism 6 for moving the adjusting block 505 is provided on the upper surface of the adjusting gear ring 503, and the telescopic mechanism 6 includes a mounting box 601 fixedly connected to the upper surface of the adjusting gear ring 503, and a micro electric push rod 602 extending to the upper surface of the mounting box 601 is fixedly installed inside the mounting box 601, and the adjusting block 505 is fixedly connected to the output end of the micro electric push rod 602.

[0048] There are four telescopic mechanisms 6 , which are distributed on the upper surface of the adjusting gear ring 503 in a ring shape.

[0049] When this embodiment is in use, under the transmission of the driving mechanism 5, and then through the telescopic action of the micro electric push rod 602, the adjustment block 505 moves upward, so as to facilitate the adjustment of the distance between the adjustment block 505 and the abutment wheel 405, thereby adjusting the frequency of the up and down reciprocating adjustment angle of the energy-saving block body 1, so as to more effectively absorb and utilize the heat generated by combustion.

[0050] The working principle of the above embodiment is:

[0051] When in use, the energy-saving block body 1 is placed inside the support ring 301. By placing the component 3 in cooperation with the energy-saving block body 1, the gas can be burned more completely, reducing harmful emissions caused by incomplete combustion, which is more environmentally friendly. The optimized combustion process can heat food faster and improve cooking efficiency. The energy-saving block body 1 is designed to be easy to install and maintain, which is convenient for users to replace or clean by themselves. Then, the speed regulating motor 501 is started by the controller to drive the transmission gear 502 to rotate, so that the transmission gear 502 engages and drives the adjustment gear ring 503 to transmit, thereby driving the adjustment block 505 to perform continuous circular motion, so that the adjustment block 505 drives the adjustment ring 402 to reciprocate up and down through the abutment wheel 405 and the guide rod 404, thereby adjusting the reciprocating angle of the energy-saving block body 1, and the contact area between the flame and the bottom of the pot can be adjusted, so that the firepower is more evenly distributed on the bottom of the pot, thereby extending the gas stove. The service life of the pot can be extended by even heating. In addition, even heating can also reduce deformation or damage of the pot bottom caused by uneven heating. The supporting effect of the supporting ring 301 and the placement groove 302 can facilitate the adjustment of the angle of the energy-saving block body 1, and the mixing ratio of gas and air can be better controlled. The movement of the abutting wheel 405 and the guide rod 404 allows the adjusting ring 402 and the reset spring 403 to reciprocate up and down. Under the elastic force of the reset spring 403, the adjusting ring 402 slightly adjusts the angle of the energy-saving block body 1, which helps to accurately control the firepower according to different cooking needs and adapt to different cooking methods.
