[0034] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0035] Referring to Figure 1 , Figure 2 and Figure 7 , the utility model relates to a kind of portable particle oven, comprising: furnace body 100, first hand piece 110 is equipped on the furnace body 100, the furnace body 100 has heating cavity 120 and the passageway 130 being communicated with the heating cavity 120;Particle feeding box 200, the particle feeding box 200 includes box 210, storage bin 220, feeding pipe 230 and burner 240, second hand piece 211 is equipped on the box 210, the box 210 is detachably connected on the side of the furnace body 100 where the passageway 130 is located, the two ends of the feeding pipe 230 are connected with the storage bin 220 and the burner 240 respectively, the burner 240 can enter or exit the heating cavity 120 along the passageway 130.

[0036] The portable pellet grill with the above structure can be separated into two independent parts when it needs to be carried out, one hand of the user holds the first hand holding part 110 to hold the furnace body 100 upward, and the other hand holds the second hand holding part 211 to hold the furnace body 100 upward, which is beneficial to balance the stress on both sides of the human body, reduces the risk of injury caused by more weight on the left or right side of the human body, improves the comfort of carrying by hand, and the furnace body 100 is relatively small in size when it is taken out or put in alone, so it is not necessary to reduce the barbecue area because of the limited storage space, so that the pellet grill is convenient for the user to carry and transport without reducing the barbecue area. Moreover, the pellet feeding box 200 and the furnace body 100 are separated into two independent parts, which is convenient to store in the trunk of the car, and the requirement for the shape and size of the storage space is lower, and more shape and size of the storage space can be adapted.

[0037] Referring to Figure 2 and Figure 4In some embodiments of the utility model, the channel mouth 130 is opened on the back plate of the furnace body 100, one of the front side wall of the box 210 and the back plate of the furnace body 100 is provided with a gourd hole 140 arranged along the height direction, and the other is provided with a mounting bolt 212 threaded in the smaller end of the gourd hole 140. It can be understood that when the furnace body 100 and the box 210 need to be assembled together, the mounting bolt 212 is threaded through the larger end of the gourd hole 140, and then the rod part of the mounting bolt 212 is moved to the smaller end of the gourd hole 140, at this time the head part of the mounting bolt 212 cannot be separated from the gourd hole 140 along the front-back direction, that is, the assembly between the furnace body 100 and the particle feeding box 200 can be completed. When the furnace body 100 and the box 210 need to be split, the mounting bolt 212 is moved from the smaller end of the gourd hole 140 to the larger end of the gourd hole 140, at this time the head part of the mounting bolt 212 can be directly pulled out from the larger end of the gourd hole 140, and the furnace body 100 and the particle feeding box 200 can be separated in the front-back direction. Through the above structure, the mounting and dismounting between the furnace body 100 and the particle feeding box 200 are very fast, the operation difficulty is low, and the furnace body 100 and the particle feeding box 200 are automatically aligned with the smaller end of the gourd hole 140 along the vertical direction under the action of their own gravity, the locking function is completed, and accidental separation of the furnace body 100 and the particle feeding box 200 due to accidental touch during the use of the particle oven is avoided. Of course, in other embodiments, other quick dismounting modes can also be used between the furnace body 100 and the particle feeding box 200, for example, bolt connection, buckle connection, strong magnetic attraction and the like, which can also realize the quick separation and assembly of the furnace body 100 and the particle feeding box 200. Taking the strong magnetic attraction mode as an example, a plurality of first magnets are arranged at the outer peripheral edge of the back plate of the furnace body 100, and correspondingly, a plurality of second magnets corresponding one by one to the first magnets are arranged at the outer peripheral edge of the front side plate of the box 210, so that the quick dismounting between the furnace body 100 and the particle feeding box 200 is realized, and the installation can be relatively stable.

[0038] In the embodiment, the two side edges of the back plate of the furnace body 100 are arranged with multiple gourd holes 140 in the height direction, the two side edges of the front side plate of the box body 210 are correspondingly arranged with multiple mounting bolts 212, the larger end of each gourd hole 140 is inserted into the head of the mounting bolt 212, and then released, under the action of the gravity of the furnace body 100, the furnace body 100 can be hung on the front side of the particle feeding box. In addition, it should be noted that the mass of the particle feeding box loaded with particles is greater than the mass of the furnace body 100, and the furnace body 100 hung on the box body 210 is more stable than the box body 210 hung on the furnace body 100. Of course, in order to enable the whole particle oven to be placed stably on the desktop, the bottom of the furnace body 100 and the bottom of the box body 210 are both provided with supporting legs. In addition, in some embodiments, the positions of the gourd hole 140 and the mounting bolt 212 can be interchanged, and in order to achieve the purpose of hanging the furnace body 100 on the front side of the particle feeding box, the gourd hole 140 is arranged on the front side plate of the box body 210 and the gourd hole 140 is large at the top and small at the bottom, the mounting bolt 212 is arranged on the back plate of the furnace body 100, the mounting bolt 212 is inserted through the larger end of the gourd hole 140 and then released, and under the action of the gravity, the rod part of the mounting bolt 212 falls into the smaller end of the gourd hole 140.

[0039] It can be understood that in the embodiment, the furnace body 100 and the particle feeding box 200 are arranged in the front-rear direction, and in other embodiments, according to the specific needs of use, the furnace body 100 and the particle feeding box 200 can also be arranged in the left-right direction. Since the furnace body 100 and the particle feeding box 200 can be divided into two independent parts, the difficulty of taking and placing the furnace body 100 alone is reduced, the area of the furnace body 100 used for barbecue does not need to be reduced, and it is ensured that a sufficient amount of food can be barbecued at one time, which is beneficial to outdoor camping activities.

[0040] Referring to Figure 1 and Figure 2In some embodiments of the utility model, the furnace body 100 is equipped with a barbecue grill 170, the rear side of the furnace body 100 is pivotally connected with a cooking cover 150 capable of being covered outside the barbecue grill 170, the front side of the cooking cover 150 is detachably connected to the furnace body 100 through a buckle lock 160, and the first hand-held part 110 is a hand holding part arranged on the front side wall of the cooking cover 150. It can be understood that the user can drive the cooking cover 150 to rotate to expose the barbecue grill 170 or to shield the barbecue grill 170 by holding the hand holding part, the efficiency of barbecue or cooking can be improved when the cooking cover 150 surrounds outside the barbecue grill 170, and the cooking cover 150 is rotated to expose the barbecue grill 170, which helps to quickly discharge the smoke gas of barbecue. Wherein, the cooking cover 150 is pivotally connected to the furnace body 100 through a hinge, when the cooking cover 150 is rotated to expose the barbecue grill 170, the hinge has rotation damping, and the center of gravity of the cooking cover 150 can also drive it to lean on the box body 210, so that the cooking cover 150 does not turn over to shield the barbecue grill 170; when carrying, the front side of the cooking cover 150 is connected to the furnace body 100 through the buckle lock 160 to prevent the cooking cover 150 from moving relative to the furnace body 100, at this time, the hand holding part can be used to lift the furnace body 100 upward, which has the effect of one thing serving two purposes. It should be noted that the burner 240 extends directly below the barbecue grill 170, and the high-temperature smoke gas generated by the combustion of particulate matter flows upward to directly or indirectly transfer to the food on the barbecue grill 170.

[0041] Referring to Figure 4 to Figure 6 In some embodiments of the utility model, the box body 210 has a container cavity 213 with an opening facing the furnace body 100, and the feeding pipe 230 is movable relative to the box body 210 to have a working state and a storage state; when the feeding pipe 230 is in the working state, the feeding pipe 230 extends out of the opening of the container cavity 213 to make the burner 240 extend into the heating cavity 120; when the feeding pipe 230 is in the storage state, the feeding pipe 230 and the burner 240 are retracted from the opening of the container cavity 213 to be at least partially accommodated in the container cavity 213.

[0042] It should be noted that the most length dimension of the feeding pipe 230 extends from the side of the box 210 to enable the burner 240 to extend into the furnace 100, and the part of the feeding pipe 230 extending from the box 210 is prone to collision, damage and injury to the human body during production, assembly and transportation, and a large amount of biomass particles are stored in the particle feeding box 200, which further causes the overall center of gravity of the particle feeding box 200 to deviate from the center position, and the user will be subjected to a large torsion force acting on the wrist when holding the second hand piece 211 to carry the particle feeding box 200, and it is very laborious to carry the particle feeding box 200 by hand, which causes difficulty in transportation and carrying, and great inconvenience to the automatic production, assembly and transfer process.

[0043] Through the above structure, the feeding pipe 230 can be switched to the storage state during the carrying of the particle feeding box 200, so as to avoid the part of the feeding pipe 230 extending from the box 210 to be prone to collision, damage and injury to the human body, reduce the volume of storage and packaging, and avoid the influence of the large deviation of the center of gravity from the center position on transportation or carrying. When assembled and used, the feeding pipe 230 can be switched to the working state extending from the cavity 213, so as to meet the installation and use requirements. It should be noted that the part or all of the feeding pipe 230 and the burner 240 entering the cavity 213 from the opening of the cavity 213 can improve or solve the above problems to different degrees, and preferably, the feeding pipe 230 and the burner 240 can be completely accommodated in the cavity 213 to avoid scratching the human body or external objects.

[0044] Referring to Figure 6In some embodiments of the utility model, the storage bin 220 is arranged at the upper part of the box 210, the feeding pipe 230 is located below the storage bin 220 and is always communicated with the storage bin 220, the feeding pipe 230 is linear and long strip-shaped, the cavity 213 has a long strip-shaped storage space below the storage bin 220, the storage bin 220 has an input port with an upward opening, the upper part of the box 210 is provided with a cover plate 214 for opening or closing the input port, and the second hand-held part 211 is a hand-held part arranged at the top of the cover plate 214. It can be understood that the particles in the storage bin 220 move downward under the action of gravity to enter the feeding pipe 230, the feeding pipe 230 is completely accommodated in the storage space of the cavity 213 and does not protrude from the outer contour of the box 210, so that the overall shape of the particle feeding box 200 is more regular, which is convenient for storage and stacking and transportation in a row, and the feeding pipe 230 located below the storage bin 220 and always communicated with the storage bin 220 can avoid leakage of particles when the feeding pipe 230 is switched between the working state and the storage state. When it is necessary to add particles, the user can hold the hand-held part to drive the cover plate 214 to open the input port, and after the addition is completed, the cover plate 214 is locked, and the feeding pipe 230 is switched to the storage state, so that the particle feeding box 200 forms the shape of a hand-held box, which is convenient for the user to carry. Specifically, in this embodiment, one side of the cover plate 214 along the width direction is rotationally connected to the box 210 through a hinge 273, and the other side of the cover plate 214 along the width direction is connected to the box 210 through a buckle lock 160.

[0045] Referring to Figure 2 、 Figure 5 and Figure 8In some embodiments of the utility model, the feeding pipe 230 is internally rotatably provided with a feeding screw 231 extending along the length direction thereof, one end of the feeding screw 231 extends out of the end of the feeding pipe 230 and is connected with a driver 232 driving the feeding screw 231 to rotate, the lower end of the storage bin 220 is provided with a discharge port 221, the top wall of the end of the feeding pipe 230 away from the burner 240 is provided with an inlet port opposite to the discharge port 221, the discharge port 221 and the inlet port are connected in communication through a rotary pipe group 250, the feeding pipe 230 can rotate around a vertical axis relative to the storage bin 220 to switch between the working state and the storage state. The particulate in the storage bin 220 moves downward into one end of the feeding pipe 230, as the driver 232 drives the feeding screw 231 to rotate, the feeding screw 231 drives the particulate to move along the feeding pipe 230 towards the burner 240, the ignition rod in the burner 240 continuously transfers heat to the particulate by heat conduction to promote the combustion of the particulate. Wherein, the feeding screw 231 can accurately control the amount of particulate supplied to the burner 240, and can also avoid the occurrence of particulate jamming. The feeding pipe 230 can rotate around the center line of the rotary pipe group 250 to rotate the feeding pipe 230 to be stored in the accommodating cavity 213 or to be unfolded outside the accommodating cavity 213, at the same time, the rotary pipe group 250 can also keep the discharge port 221 of the storage bin 220 and the inlet port of the feeding pipe 230 in sealed communication, preventing particulate leakage, the feeding pipe 230 adopts this structure, which is very convenient to unfold and store relative to the box body 210, and is easy to operate. Of course, in other embodiments, the rotary pipe group 250 can also be replaced by a corrugated hose, and the feeding pipe 230 is not limited to the rotating storage mode, but can also use swinging, moving and other modes.

[0046] Referring to Figure 8In some embodiments of the utility model, the rotating tube group 250 includes a first inner circular tube 251 and a first outer circular tube 252 sleeved on the outside of the first inner circular tube 251, the central axes of the first inner circular tube 251 and the first outer circular tube 252 are coaxial with the vertical axis, one of the first inner circular tube 251 and the first outer circular tube 252 is arranged at the discharge port 221, and the other is arranged at the feeding port. In the embodiment, the bottom of the storage bin 220 is fixed with a first mounting plate 253 by screws, the first inner circular tube 251 is fixedly arranged on the first mounting plate 253, the top of the feeding pipe 230 is fixed with a second mounting plate 254 by screws, the first outer circular tube 252 is fixedly arranged on the second mounting plate 254, the first inner circular tube 251 and the first outer circular tube 252 are slidingly nested to realize relative rotation, and the whole formed by the first inner circular tube 251 and the first outer circular tube 252 is used for both particle transmission and relative rotation between the feeding pipe 230 and the storage bin 220, so that a rotating structure does not need to be additionally arranged, and the effect of one thing serving two purposes is achieved.

[0047] Referring to Figure 5 and Figure 8 In some embodiments of the utility model, a rotating support mechanism 260 is arranged between the lower side wall of the feeding pipe 230 and the inner bottom wall of the box body 210, and the rotating axis of the rotating support mechanism 260 is coaxial with the vertical axis. It can be understood that when the relative rotation between the feeding pipe 230 and the storage bin 220 is realized only by the first inner circular tube 251 and the first outer circular tube 252, the feeding pipe 230 is essentially a cantilever, and the feeding pipe 230 cannot be stably supported, which increases the load on the first inner circular tube 251 and the first outer circular tube 252, and may cause abnormal rotation sound and unsmooth rotation. The rotating support mechanism 260 can improve or solve this problem. Specifically, in the embodiment, a rectangular frame 290 is further arranged outside the feeding pipe 230, the feeding pipe 230 is arranged inside the rectangular frame 290, the rotating support mechanism 260 includes a second inner circular tube 261 and a second outer circular tube 262 sleeved on the outside of the second inner circular tube 261, the central axes of the second inner circular tube 261 and the second outer circular tube 262 are coaxial with the vertical axis, the second inner circular tube 261 is arranged on the inner bottom wall of the box body 210, the second outer circular tube 262 is arranged on the lower side wall of the rectangular frame 290, and the second inner circular tube 261 and the second outer circular tube 262 are gap-fitted to guide the rotation of the feeding pipe 230. Referring to Figure 5The gas passage 291 is formed between the rectangular frame 290 and the feeding pipe 230, the burner 240 comprises a combustion box in the gas passage 291 and an ignition rod penetrating through the side wall of the combustion box, a plurality of air inlet holes are formed in the outer peripheral wall of the combustion box, and the rectangular frame 290 is provided with a fan 280 for inputting external gas into the gas passage 291, so that oxygen is continuously provided for the combustion of the particulate matter.

[0048] Referring to Figure 6 and Figure 7 In some embodiments of the present application, the feeding pipe 230 and the burner 240 can be entirely accommodated in the accommodating cavity 213, and the switch mechanism 270 for opening or closing the side opening of the accommodating cavity 213 is movably arranged on the box body 210, so as to protect the feeding pipe 230 accommodated in the accommodating cavity 213 and avoid accidental ejection of the feeding pipe 230.

[0049] Referring to Figure 4 and Figure 7 In some embodiments of the present application, the switch mechanism 270 comprises a fixed plate 271 mounted on the front side wall of the box body 210 and a baffle 272 rotatably connected to the fixed plate 271 through a hinge 273, the pivot of the hinge 273 is horizontally arranged, and the baffle 272 can be stably turned up to open the opening of the accommodating cavity 213 or turned down to close the opening of the accommodating cavity 213.
