If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figures 1 to 3 The utility model is a small portable pellet grill, comprising: a grill body 100, a conveying pipe 200 arranged in the left-right direction is provided on the rear side of the grill body 100, a feeding screw 300 is rotatably arranged in the conveying pipe 200, and the feeding screw 300 can convey pellets from both ends of the conveying pipe 200 to the middle of the conveying pipe 200, and the middle of the conveying pipe 200 is connected to a transmission mechanism 400 arranged obliquely downward, and the transmission mechanism 400 is extended toward the front end of the grill body 100, and the end of the transmission mechanism 400 away from the conveying pipe 200 is connected to a combustion device 500.

[0027] The oven with the above structure sets the feed screw 300 in a horizontal manner arranged in the left-right direction. When the feed screw 300 rotates, the particles can be transported from both ends of the conveying pipe 200 to the middle of the conveying pipe 200. The particles transported to the middle of the conveying pipe 200 are transported obliquely downward and forward to the combustion device 500 via the transmission mechanism 400, thereby greatly reducing the size of the oven in the front-to-back direction, improving the compactness of the structure of the particle oven, and achieving the effect of miniaturization and portability.

[0028] It should be explained that due to the use requirements of barbecue, the dimension of the oven along the left and right direction is generally set to be longer to meet the purpose of placing more food ingredients, while the traditional feeding screw 300 arranged along the front and back direction not only makes the size of the entire oven large, but also makes it inconvenient for users to take and place ingredients when cooking, which is not conducive to miniaturized design and carrying and transportation, etc.

[0029] See also Figure 1 and Figure 2 In some embodiments of the utility model, the feeding screw 300 is provided with a first spiral section 310 and a second spiral section 320 with opposite thread directions, the first spiral section 310 extends along one end of the feeding screw 300 to the middle of the feeding screw 300, and the second spiral section 320 extends along the other end of the feeding screw 300 to the middle of the feeding screw 300, and a discharge area 330 connected to the transmission mechanism 400 is formed between the ends of the first spiral section 310 and the second spiral section 320 that are close to each other, and one end of the feeding screw 300 extends out of the conveying pipe 200 to connect to a driving device 340 that drives it to rotate. Specifically, the driving device 340 is a motor that drives the feeding screw 300 to rotate, and the motor is arranged along the left-right direction of the oven body 100, and does not occupy the space in the front-back direction. When a large amount of particles are poured into the conveying pipe 200, the particles at both ends of the feeding screw 300 can move toward the middle of the feeding screw 300 under the push of the first spiral section 310 and the second spiral section 320, and the particles at both ends of the feeding screw 300 are orderly gathered in the discharge area 330 and then enter the transmission mechanism 400. The feeding screw 300 of the above structure is simple in structure, low in cost, and occupies a small space. Of course, in other embodiments, the feeding screw 300 can also be replaced by two coaxially arranged screws, and the ends of the two screws that are away from each other are driven to rotate by a motor. The two motors rotate in opposite clockwise directions, which can also realize the orderly gathering of the particles at both ends in the discharge area 330.

[0030] See also Figure 2In some embodiments of the utility model, the conveying pipe 200 is in a horizontal cylindrical shape, and the upper side of the outer peripheral wall of the conveying pipe 200 is provided with a first input port 241 opposite to the first spiral segment 310 and a second input port 242 opposite to the second spiral segment 320. The first input port 241 and the second input port 242 are extended along the length direction of the conveying pipe 200 to match the length dimensions of the first spiral segment 310 and the second spiral segment 320 respectively. That is, part of the particles can enter the first spiral segment 310 along the first input port 241, and part of the particles can enter the second spiral segment 320 along the second input port 242, so as to avoid the first spiral segment 310 and the second spiral segment 320 from repeatedly interfering with the movement path of the nearby particles during the rotation process, and facilitate the particles to enter the conveying pipe 200 in an orderly manner. Among them, the length dimension of the first input port 241 matches or is consistent with the length dimension of the first spiral segment 310, and the length dimension of the second input port 242 matches or is consistent with the length dimension of the second spiral segment 320, so as to ensure the flow rate of the conveyed particles and alleviate the blockage.

[0031] See also Figure 2 In some embodiments of the utility model, a long notch 210 extending along the length direction is provided on the upper side of the outer peripheral wall of the conveying pipe 200, and a first inclined long plate 220 and a second inclined long plate 230 are provided on opposite sides of the long notch 210 along the length direction, respectively. The first inclined long plate 220 and the second inclined long plate 230 are symmetrically arranged to form an outward opening, and a long cover plate 240 is provided on the upper edge of the first inclined long plate 220 and the second inclined long plate 230, and the first input port 241 and the second input port 242 are provided on the long cover plate 240. The above structure is conducive to reducing the difficulty of production and manufacturing, and the provision of the first inclined long plate 220 and the second inclined long plate 230 is conducive to smoothly guiding the particles to the transmission mechanism 400.

[0032] See also Figure 1 and Figure 2In some embodiments of the utility model, the strip cover plate 240 has a baffle portion 250 for covering the discharge area 330 between the first input port 241 and the second input port 242, and a flow guide 260 is installed on the baffle portion 250. The flow guide 260 is provided with a first slope 261 and a second slope 262 arranged symmetrically, and the first slope 261 and the second slope 262 guide the particles toward the first input port 241 and the second input port 242, respectively. It should be noted that if the particles are directly piled in the discharge area 330, there will be a blockage. Using the baffle portion 250 to block the particles can avoid this problem. However, the particles accumulated on the baffle portion 250 can also cause the problem of blockage. The first slope 261 and the second slope 262 on the flow guide 260 can solve or alleviate the above problem.

[0033] In some embodiments of the utility model, an output port 270 is provided at the front side of the middle part of the conveying pipe 200, the transmission mechanism 400 includes a chute plate connected to the output port 270 at one end and arranged to tilt forward and downward, and the combustion device 500 includes a combustion box 510 connected to the other end of the chute plate, the combustion box 510 has a combustion chamber open upward, and an ignition rod 520 is arranged in the combustion chamber. It can be understood that after the particles discharged from the output port 270 enter the chute plate, the particles are squeezed against each other and slide downward and forward into the combustion chamber of the combustion box 510 under the action of gravity, without the need to set a power device, which simplifies the structure of the product and is conducive to the miniaturization of the oven.

[0034] See also Figure 1 In some embodiments of the utility model, the chute plate is provided with flanges bent upward on both sides along its length direction, and a housing assembly 600 is provided outside the chute plate and the combustion box 510. The housing assembly 600 has a limit plate 610 located above the chute plate and arranged parallel to the chute plate, and a transmission channel is defined between the limit plate and the chute plate. The combination of the chute plate and the limit plate 610 is convenient for assembly and is more conducive to the rapid transmission of particles than the structure of the cylindrical channel.

[0035] See also Figure 1 and Figure 2In some embodiments of the utility model, the outer peripheral wall of the combustion box 510 is provided with a first air supply hole connected to the combustion chamber, the shell assembly 600 and the outer peripheral wall of the combustion box 510 define an air duct chamber 620 connected to the first air supply hole, and the inner bottom wall of the shell assembly 600 and the outer bottom surface of the chute plate define a storage space located within the air duct chamber 620, and the storage space is provided with a fan 700 with an output end facing forward. It can be understood that the gas blown forward by the fan 700 can be poured into the air duct chamber 620 in a horizontal direction, and then poured into the interior of the combustion chamber from each first air supply hole. When the gas flows upward along the opening of the combustion chamber, the output end of the fan 700 is directly opposite to the outer peripheral wall of the combustion box 510. The above structure is conducive to the supply of a large amount of oxygen to ensure that the particulate matter can be fully burned. Placing the fan 700 at the position below the chute plate is conducive to improving the compactness of the structure.

[0036] See also Figure 3 In some embodiments of the utility model, a first plate 810 facing the opening of the combustion chamber is provided above the combustion box 510, and a plurality of first strip-shaped through holes 811 are provided through the first plate 810. A second plate 820 is movably provided on the first plate 810, and a plurality of second strip-shaped through holes 821 corresponding to the first strip-shaped through holes 811 are provided through the second plate 820. The second plate 820 moves on the first plate 810 to adjust the overlap between the second strip-shaped through holes 821 and the corresponding first strip-shaped through holes 811. It should be noted that the more overlap between the second strip-shaped through holes 821 and the corresponding first strip-shaped through holes 811, the more flames can spread upwards. By adjusting the overlap between the second strip-shaped through holes 821 and the first strip-shaped through holes 811, the firepower acting on the food can be adjusted, and the firepower can also be made more uniform.

[0037] See also Figure 3In some embodiments of the utility model, the oven body 100 is provided with an oil receiving pan 830 located above the second flat plate 820, the oil receiving pan 830 is penetrated by a plurality of third strip through holes 831, the third strip through holes 831 are substantially orthogonal to the first strip through holes 811, a movable plate 840 is provided on the oil receiving pan 830, the movable plate 840 is penetrated by a plurality of fourth strip through holes 841 corresponding one to one with the third strip through holes 831, the movable plate 840 moves on the oil receiving pan 830 to adjust the overlapping portion of the fourth strip through holes 841 and the corresponding third strip through holes 831. It should be noted that the third strip through holes 831 are roughly orthogonal to the first strip through holes 811 to form a grid-like perforations in the vertical direction. These perforations allow flames or smoke to pass upward. When the fourth strip through holes 841 are completely misaligned with the corresponding third strip through holes 831, no flame can spread directly upward, and the oven is in a smoke heating working mode, thereby expanding the use function of the oven.

[0038] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
