[0027] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides an air-intake feed ignition mechanism 1, including a feed box 11, a feed push assembly 12, an igniter 13 and a fan 14. The igniter 13 can be a common electronic rod-shaped igniter on the market. The igniter 13 is installed on the feed box 11. The feed push assembly 12 includes a motor 121, a material conduit 122 and a pusher 123. The pusher 123 is placed in the material conduit 122 along the length direction of the material conduit 122. A pushing channel is provided between the member 123 and the inner wall of the material conduit 122, the motor 121 is connected to the pushing member 123 and drives the pushing member 123 to rotate so as to push the material entering the pushing channel, the feed box 11 is provided with a feed port 1111, a connecting feed channel is provided between the material conduit 122 and the feed port 1111, the fan 14 is provided on the feed box 11, the feed box 11 is provided with an air inlet 1122 and an air outlet, and the air inlet 1122 is connected to the air outlet end of the fan 14.

[0028] By setting up the feed box 11, the feed push assembly 12, the igniter 13 and the fan 14 are all arranged on the feed box 11, and the structure is compact, which reduces the occupied space in the barbecue grill and is conducive to the compact or miniaturized design of the barbecue grill. In addition, the modular design of the feed push assembly 12, the igniter 13 and the fan 14 facilitates disassembly, assembly and maintenance.

[0029] When the air inlet, feeding and ignition mechanism 1 is actually used in a barbecue oven, the feed box 11 is connected to the feed bin by the feed port 1111, the outlet end of the material conduit 122 is connected to the combustion chamber, the air outlet of the feed box 11 is aligned with the combustion chamber, the material in the feed bin reaches the material conduit 122 from the feed port 1111, the material is pushed to the combustion chamber by the pusher 123, and the material is ignited by the igniter 13 to achieve the release of the material combustion and heat in the combustion chamber. By controlling the rotation speed of the pusher 123 through the motor 121, the feeding rate to the combustion chamber can be controlled to control the combustion speed of the material, thereby controlling the overall temperature of the entire stewing and roasting chamber. In addition, by controlling the size of the air supplied to the combustion chamber by the fan 14, the combustion speed of the material can also be controlled, thereby controlling the overall temperature of the entire stewing and roasting chamber. The combination of the two has a better ability to control the combustion speed. It can be understood that the control of the fan 14 and the motor 121 can be achieved by a configured controller.

[0030] In one embodiment, if Figure 2 As shown, the feed box 11 includes a feed shell 111 and a support shell 112. The feed shell 111 is provided with a feed port 1111. The fan 14 is mounted on the support shell 112. The support shell 112 is provided with an air inlet 1122 and an air outlet. The material conduit 122 is passed through the support shell 112. The igniter 13 is mounted on the support shell 112. Through such a structural arrangement, the structure is made more compact.

[0031] In one embodiment, if Figure 2 As shown, a feed port 1112 is provided at the bottom of the feed shell 111, a material inlet 1221 is provided at the top of the material conduit 122 corresponding to the position of the feed port 1112, the feed port 1112 is connected with the material inlet 1221 to form a feed channel, and the feed shell 111 is provided with a feed cavity 1113 connected with the feed port 1111 and the feed port 1112, and the bottom surface of the feed cavity 1113 close to the feed port 1111 is an inclined surface.

[0032] The material entering the feed housing 111 from the feed port 1111 passes through the feed cavity 1113 and reaches the drop port 1112. Under the action of its own gravity, the material falls from the drop port 1112 to the material inlet 1221 and then enters the material conduit 122. Since the bottom surface of the feed cavity 1113 near the feed port 1111 is an inclined surface, the material entering from the feed port 1111 can reach the drop port 1112 more smoothly, thereby improving the smoothness of the material movement.

[0033] like Figure 1-Figure 2As shown, one side of the support shell 112 in the length direction is connected to the feed shell 111, and one side of the support shell 112 in the length direction is provided with a through hole 1121 for the material conduit 122 to pass through. The material conduit 122 passes through the through hole 1121, and the support shell 112 can serve as a supporting structure for the material conduit 122. It can be understood that since the material conduit 122 is penetrated in the support shell 112, the material conduit 122 utilizes the hollow space of the support shell 112 without occupying additional space, thereby making the overall structure of the air intake, feed and ignition mechanism 1 more compact.

[0034] The material conduit 122 is arranged obliquely on the support shell 112, and the outlet end of the material conduit 122 is in a relatively high posture. At the same time, an air outlet 1222 is provided near the outlet end of the material conduit 122. The advantage of this design is that the problem of material combustion backfire can be avoided.

[0035] like Figure 1 As shown, the air outlet is arranged on the other side of the length direction of the supporting shell 112, and the outer end of the material conduit 122 passes through the through hole 1121 and out of the air outlet. This design is more conducive to the connection between the outlet end of the material conduit 122 and the combustion chamber.

[0036] In one embodiment, the fan 14 is installed on one side of the width direction of the support housing 112, and an air inlet 1122 is provided on one side of the width direction of the support housing 112 corresponding to the air outlet end of the fan 14. The advantage of this design is that the space in the width direction of the support housing 112 is utilized, the structural layout is more reasonable, and the structure is more compact.

[0037] In one embodiment, the igniter 13 is arranged in the support shell 112 along the length direction of the support shell 112, and the ignition head 132 of the igniter 13 extends out of the air outlet. The advantage of this design is that the igniter 13 utilizes the hollow space of the support shell 112 without occupying additional space, thereby making the overall structure of the air intake and material feeding ignition mechanism 1 more compact.

[0038] In this embodiment, in order to facilitate the passage of the connecting wire connected to the terminal of the igniter 11, a wire passage hole is provided in the support shell 112. The wire passage hole and the through hole 1121 are located on the same side of the support shell 112. A sealing ring 131 is provided on the wire passage hole to prevent air leakage from the wire passage hole.

[0039] like Figure 2As shown, in one embodiment, the pusher 123 includes a drive shaft 1231 and a spiral guide rod 1232, one end of the drive shaft 1231 is connected to the output shaft of the motor 121, and the other end of the drive shaft 1231 is connected to the spiral guide rod 1232, and a pusher channel is formed between the spiral guide rod 1232 and the inner wall of the material conduit 122. The motor 121 drives the drive shaft 1231 to rotate, thereby rotating the spiral guide rod 1232, and the material entering from the material inlet 1221 of the material conduit 122 is pushed into the combustion chamber under the rotation of the spiral guide rod 1232.

[0040] The embodiment of the utility model further provides a barbecue oven, comprising the above-mentioned air inlet, material feeding and ignition mechanism 1. It should be noted that, except for the above-mentioned air inlet, material feeding and ignition mechanism 1, other structures of the barbecue oven can be the same as those on the market, and other structures of the barbecue oven are not described here.

[0041] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
