Detailed implementation mode

[0025] The following further describes the present invention in detail in conjunction with the accompanying drawings and specific implementation modes, but does not limit the protection scope and application scope of the present invention.

[0026] Embodiment 1

[0027] An energy-saving gas stove with air premixing function, as Figures 1-7 shown, includes a furnace body 1, a connecting pipe 2, a burner head 3, a control valve 4 and a gas cylinder 5; a control valve 4 is fixedly connected inside the furnace body 1; a connecting pipe 2 is fixedly connected to the control valve 4; a burner head 3 with an air premixing function is fixedly connected inside the furnace body 1, and the jet pipe inside the burner head 3 is communicated with the connecting pipe 2; the connecting pipe 2 is detachably connected to the gas cylinder 5;

[0028] It also includes a folding plate 101, a fixing buckle 102 and a support assembly; two folding plates 101 are rotatably connected to the furnace body 1; each folding plate 101 is connected with a fixing buckle 102, and all the fixing buckles 102 are buckled with each other; each folding plate 101 is connected with a plurality of support assemblies.

[0029] The folding plate 101 is arranged in an inclined plane shape, so as to guide the liquid moisture generated during the cooking of the external pot body outward, avoiding the liquid remaining on the folding plate 101 and being inconvenient to clean after solidification.

[0030] There are two inclined slots 11 opened on the upper side of the furnace body 1, and the inclined slots 11 are located below the rotating shaft of the folding plate 101, so that impurities falling onto the rotating shaft of the folding plate 101 during the cooking process fall out from the inclined slots 11, preventing the impurities from getting stuck at the rotating shaft of the folding plate 101 and causing difficulty in folding the folding plate 101.

[0031] The support assembly includes support feet 103 and support plates 104; each folding plate 101 is provided with two storage slots 1001, and the two storage slots 1001 are arranged in a flare shape; two support feet 103 are rotatably connected to each storage slot 1001; two support feet 103 located in the same storage slot 1001 are jointly rotatably connected to a support plate 104.

[0032] The support plate 104 is made of alloy material to improve the support strength and service life of the support plate 104.

[0033] One inclined notch 1003 is opened at each end of each storage slot 1001 away from the burner 3, which is convenient for the user to pick up the support plate 104 from the storage slot 1001 through the inclined notch 1003 with a finger. And during the cooking process, there will be impurities or oil stains falling into the storage slot 1001. Therefore, after cooking, the user uses an external toothpick to scrape out the impurities and oil stains in the storage slot 1001 from the inclined notch 1003, which is convenient for cleaning the storage slot 1001.

[0034] During use, first manually separate the fixing buckles 102 on the two folding plates 101, remove the gas cylinder 5 clamped between the two folding plates 101 and install it on the side of the furnace body 1, and connect the connecting pipe 2 and the gas cylinder 5. Subsequently, manually unfold the two folding plates 101 into a flat shape. Then, manually pull up the support plate 104, and the support plate 104 drives the support feet 103 to rotate until the support feet 103, the support plate 104 and the bottom of the storage slot 1001 form a parallelogram, as Figure 6 shown, so that the support plate 104 is as close to the burner 3 as possible. Since one of the support feet 103 abuts against the inner wall of the storage slot 1001 and cannot rotate further, the support feet 103 fix the support plate 104. Pull up and fix the four support plates 104 in turn, as Figure 1 shown. Subsequently, place an external pot body on the four support plates 104, and manually rotate the knob to make the gas in the gas cylinder 5 enter the burner 3 through the connecting pipe 2. After the burner 3 premixes the external air and the gas, manually press the button to make the control valve 4 ignite the burner 3, and then the burner 3 heats the external pot body for cooking;

[0035] When not in use, remove the gas cylinder 5, fold up this gas stove, rotate the two folding plates 101 upward to clamp the gas cylinder 5, and fasten the two fixing buckles 102 to fix the two folding plates 101, asFigure 2 As shown, when not in use, the volume of the gas stove can be reduced, making it convenient to carry. When in use, the two unfolded folding plates 101 increase the supporting surface for the external pot body, improving the stability of the external pot body.

[0036] Embodiment 2

[0037] Based on Embodiment 1, as Figures 1-7 shown, it further includes a rotating rod 201 and a partition plate 202; each folding plate 101 is provided with a rectangular groove 1002; each folding plate 101 is connected to a rotating rod 201; each rotating rod 201 is fixedly connected to a partition plate 202 made of heat-insulating material, and the partition plate 202 is located within the rectangular groove 1002.

[0038] It further includes a clamping block 203; each folding plate 101 is fixedly connected to two clamping blocks 203; all the clamping blocks 203 located on the same folding plate 101 are detachably connected to the corresponding rotating rod 201.

[0039] It further includes a rotating plate 204; the stove body 1 is rotatably connected to two rotating plates 204.

[0040] Since the burner head 3 will have residual heat after heating is completed, if the gas cylinder 5 is directly placed above the burner head 3, the residual heat of the burner head 3 will heat the gas cylinder 5, causing the gas cylinder 5 to overheat in a short time, posing a safety hazard. Therefore, after the folding plate 101 rotates upward to a vertical state, the partition plate 202 is turned out of the rectangular groove 1002 around the rotating rod 201, so that the partition plate 202 is placed horizontally above the burner head 3, and then the removed gas cylinder 5 is placed on the partition plate 202, as Figure 2 shown, thereby isolating the residual heat of the burner head 3 and preventing the residual heat of the burner head 3 from heating the gas cylinder 5.

[0041] During the cooking process, a lot of impurities or oil stains will fall, and the impurities or oil stains will fall on the partition plate 202 and remain. When the partition plate 202 is flipped above the burner head 3, the impurities or oil stains remaining on the partition plate 202 will fall on the burner head 3, thereby polluting the burner head 3. Therefore, by first detaching the rotating rod 201 and the partition plate 202 from the clamping block 203 for timely cleaning, it is avoided that the impurities or oil stains are solidified on the partition plate 202, and the partition plate 202 rotates within the clamping block 203 during normal rotation.

[0042] During the cooking process, the external wind will blow the flame of the burner head 3, causing the flame to go out. Therefore, when in use, the rotating plate 204 is turned up to block the external wind and improve the combustion stability of the burner head 3.

[0043] Embodiment 3

[0044] Based on Embodiment 2, as Figure 3 andFigure 4 As shown, the furnace body 1 is composed of a furnace bottom 12, a sliding plate 13 and a rectangular plate 14; the furnace bottom 12 is slidably connected to the two sliding plates 13, and the sliding plate 13 is rotatably connected to the folding plate 101; the two sliding plates 13 are fixedly connected to the rectangular plate 14; the rectangular plate 14 is provided with a circular hole 141, and the circular hole 141 cooperates with the furnace head 3.

[0045] When in use, the sliding plate 13, the rectangular plate 14, the folding plate 101 and the parts connected thereto are manually pushed to move backward until the circular hole 141 is aligned with the burner head 3. Figure 3 and Figure 4 As shown, when not in use, the sliding plate 13 is in contact with the furnace bottom 12, and the circular hole 141 is staggered with the furnace head 3, as shown in FIG. Figure 1 , Figure 2 As shown, the space at the furnace bottom 12 is further utilized to reduce the volume of the furnace body 1 and improve portability. At the same time, the sliding plate 13 covers and protects the pipe opening of the connecting pipe 2. At the same time, since the circular hole 141 and the burner head 3 are staggered, the rectangular plate 14 blocks the residual heat of the burner head 3, further reducing the amount of heat transferred from the residual heat of the burner head 3 to the gas cylinder 5. At the same time, the rectangular plate 14 covers and protects the burner head 3.

[0046] The above embodiments are provided for persons familiar with the art to implement or use the present invention. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
