DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0020] Example 1

[0021] An energy-saving gas furnace with air premixing function, such as Figure 1-Figure 7 As shown, it includes a furnace body 1, a connecting pipe 2, a burner head 3, a control valve 4 and a gas cylinder 5; the control valve 4 is fixedly connected to the furnace body 1; the control valve 4 is fixedly connected to the connecting pipe 2; the burner head 3 with an air premixing function is fixedly connected to the furnace body 1, and the injection pipe in the burner head 3 is connected to the connecting pipe 2; the connecting pipe 2 is detachably connected to the gas cylinder 5; It also includes a folding plate 101, a fixing buckle 102 and a supporting assembly; the furnace body 1 is rotatably connected to two folding plates 101; each folding plate 101 is connected to a fixing buckle 102, and all the fixing buckles 102 are buckled with each other; each folding plate 101 is connected to a number of supporting assemblies.

[0022] The folding plate 101 is arranged in an inclined shape, so as to guide the liquid generated by the external pot during cooking to the outside, thereby preventing the liquid from remaining on the folding plate 101 and being inconvenient to clean after solidification.

[0023] Two inclined grooves 11 are provided on the upper side of the furnace body 1, and the inclined grooves 11 are located below the rotating shaft of the folding plate 101, so that impurities that fall onto the rotating shaft of the folding plate 101 during cooking can fall out of the inclined grooves 11, thereby preventing the impurities from being stuck at the rotating shaft of the folding plate 101, making it difficult to fold the folding plate 101.

[0024] The supporting assembly includes a support leg 103 and a support plate 104; each folding plate 101 is provided with two storage slots 1001, and the two storage slots 1001 are arranged in an eight-shaped shape; each storage slot 1001 is rotatably connected to two support legs 103; the two support legs 103 located in the same storage slot 1001 are rotatably connected to a support plate 104 together.

[0025] The support plate 104 is made of alloy material, which improves the support strength and service life of the support plate 104 .

[0026] Each storage slot 1001 is provided with an inclined notch 1003 at one end away from the stove head 3, so that the user can use his fingers to pick up the support plate 104 from the storage slot 1001 through the inclined notch 1003. During the cooking process, impurities and grease will fall into the storage slot 1001. Therefore, after cooking, the user can use an external toothpick to pick out the impurities and grease in the storage slot 1001 from the inclined notch 1003, which is convenient for cleaning the storage slot 1001.

[0027] When in use, the fixing buckles 102 on the two folding plates 101 are manually separated from each other, the gas cylinder 5 sandwiched between the two folding plates 101 is removed and installed on the side of the furnace body 1, and the connecting pipe 2 is connected to the gas cylinder 5. Then, the two folding plates 101 are manually unfolded into a flat shape, and then the support plate 104 is manually pulled upward, and the support plate 104 drives the support leg 103 to rotate until the support leg 103, the support plate 104 and the bottom of the storage slot 1001 form a parallelogram, as shown in FIG. Figure 6 As shown, the support plate 104 is brought as close to the burner head 3 as possible. Since one of the support legs 103 is against the inner wall of the storage groove 1001 and cannot continue to rotate, the support leg 103 fixes the support plate 104, and the four support plates 104 are pulled up and fixed in sequence, as shown in FIG. Figure 1 As shown, the external pot is then placed on the four support plates 104, and the knob is manually rotated to allow the gas in the gas cylinder 5 to enter the burner 3 through the connecting pipe 2. After the burner 3 premixes the outside air and the gas, the button is manually pressed to ignite the control valve 4 to ignite the burner 3, and then the burner 3 heats the external pot for cooking; When not in use, the gas cylinder 5 is removed, the gas stove is folded up, the two folding plates 101 are rotated upward to clamp the gas cylinder 5, and the two fixing buckles 102 are buckled together to fix the two folding plates 101. Figure 2As shown, the volume of the gas stove is reduced when not in use, making it easier to carry. When in use, the two unfolded folding plates 101 increase the supporting surface of the external pot body and improve the stability of the external pot body.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1-Figure 7 As shown, it also includes a rotating rod 201 and a partition 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 202 made of a heat-insulating material, and the partition 202 is located in the rectangular groove 1002.

[0030] It also includes a clamping block 203 ; each folding plate 101 is fixedly connected to two clamping blocks 203 ; all the clamping blocks 203 on the same folding plate 101 are detachably connected to the corresponding rotating rod 201 .

[0031] It also includes a rotating plate 204; the furnace body 1 is rotatably connected to the two rotating plates 204.

[0032] Since the burner head 3 will have residual heat after heating, if the gas cylinder 5 is placed directly 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 is rotated upward to a vertical state, the partition 202 is turned out from the rectangular groove 1002 around the rotating rod 201, so that the partition 202 is placed above the burner head 3 in a horizontal state, and then the disassembled gas cylinder 5 is placed on the partition 202. Figure 2 As shown, the residual heat of the burner head 3 is isolated to prevent the residual heat of the burner head 3 from heating the gas cylinder 5.

[0033] Since a lot of impurities or oil stains will fall during the cooking process, the impurities or oil stains will fall onto the partition 202 and cause residues. When the partition 202 is flipped over the burner head 3, the impurities or oil stains remaining on the partition 202 will fall onto the burner head 3, thereby causing pollution to the burner head 3. Therefore, the rotating rod 201 and the partition 202 are first removed from the block 203 for timely cleaning to prevent impurities or oil stains from solidifying on the partition 202. The partition 202 is stuck in the block 203 and rotates during normal rotation.

[0034] During the cooking process, the external wind may blow the flame of the burner head 3 and cause the flame to go out. Therefore, when in use, the rotating plate 204 is flipped up to block the external wind and improve the combustion stability of the burner head 3.

[0035] Example 3

[0036] On the basis of Example 2, Figure 3 and Figure 4As 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.

[0037] 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.

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.
