[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] like Figures 1 to 4 As shown, a multifunctional accessory for a wood-burning stove includes a smoke collecting box 1, the smoke collecting box 1 is used to be connected to a wood-burning stove 100, a smoke collecting cavity 11 is formed in the smoke collecting box 1, and the smoke collecting box 1 is also provided with a smoke inlet 12 and a smoke outlet 13 connected to the smoke collecting cavity 11, the smoke inlet 12 and the smoke outlet 13 are staggered, the smoke inlet 12 is connected to the smoke exhaust pipe 101 of the wood-burning stove 100, and the smoke outlet 13 is connected to the atmosphere. The smoke outlet 13 is provided with an exhaust smoke pipe 15. The smoke inlet 12 is plugged into the smoke exhaust pipe 101 and is clearance-matched. The smoke inlet 12 and the smoke outlet 13 are respectively located at the two ends of the smoke collecting box 1.

[0037] Based on the above embodiments, the present utility model aims to solve the problem of providing a multifunctional accessory for a wood-burning stove, including a smoke collecting box 1, wherein the smoke collecting box 1 is used to be connected to a wood-burning stove 100, wherein a smoke collecting cavity 11 is formed in the smoke collecting box 1, and wherein the smoke collecting box 1 is further provided with a smoke inlet 12 and a smoke outlet 13 respectively connected to the smoke collecting cavity 11, wherein the smoke inlet 12 and the smoke outlet 13 are staggered, wherein the smoke inlet 12 is connected to a smoke exhaust pipe 101 of the wood-burning stove 100, and the smoke outlet 13 is connected to the atmosphere. The smoke inlet 12 and the smoke outlet 13 are located at both ends of the smoke collecting box 1. The smoke enters the smoke collecting box 1 from the smoke inlet 12 located at the lower end of the smoke collecting box 1, and the smoke is discharged from the smoke outlet 13 located at the upper end of the smoke collecting box 1 after two 90° turns, such as Figure 3 As shown, it can effectively prevent sparks from being discharged. At the same time, the setting of the smoke collecting box 1 increases the travel of the smoke, which can prevent heat from being discharged directly from the smoke exhaust pipe 101. The smoke collecting box 1 is equivalent to a fire wall, which increases the heat utilization rate. The diameter of the smoke inlet 12 is larger than the outer diameter of the smoke exhaust pipe 101, so that a gap is formed between the smoke inlet 12 and the smoke exhaust pipe 101. The gap acts as an air inlet to supply oxygen, so that the incompletely burned materials in the wood stove 100 are burned again in the smoke collecting box 1, which further prevents sparks from being discharged and improves the combustion efficiency. The smoke inlet 12 and the smoke outlet 13 are located at both ends of the smoke collecting box 1. The relative distance between the smoke inlet 12 and the smoke outlet 13 is as long as possible, so that the travel of the smoke in the smoke collecting box 1 is as long as possible, which is more conducive to the storage of heat and the reduction of the discharge of sparks.

[0038] As another preferred embodiment of the present invention, the smoke collecting box 1 is detachably connected to the wood stove 100. The smoke collecting box 1 is placed on the upper end of the wood stove 100, and the smoke collecting box 1 is provided with a connecting bracket 14. The bottom of the connecting bracket 14 is provided with a positioning mechanism 141 that cooperates with the wood stove 100. The positioning mechanism 141 includes a U-shaped groove 1411, and the wood stove 100 is provided with a positioning column 102 that cooperates with the U-shaped groove 1411. The positioning mechanism 141 also includes a bending portion 1412 that cooperates with the upper end surface of the wood stove 100, and the smoke collecting box 1 is placed on the wood stove 100 through the bending portion 1412. In this embodiment, Figure 1 , Figure 4As shown, the connecting bracket 14 includes a first connecting bracket 14 and a second connecting bracket 14 respectively arranged at the front end and the rear end of the smoke collecting box 1. The first connecting bracket 14 and the second bracket are detachably connected to the wood stove 100. The smoke collecting box 1 can be removed by the first connecting bracket 14 and the second bracket during storage or transportation to reduce the packaging volume, and then installed when used. A positioning mechanism 141 that cooperates with the wood stove 100 is provided at the bottom of the connecting bracket 14. The design of the positioning mechanism 141 facilitates the rapid installation of the smoke collecting box 1 to the wood stove 100. The positioning mechanism 141 includes a U-shaped groove 1411, and the wood stove 100 is provided with a positioning column 102 that cooperates with the U-shaped groove 1411. In this embodiment, as Figure 1 , Figure 4 As shown, the positioning column 102 adopts a stepped screw. When installing, the U-shaped groove 1411 is just stuck in the stepped position of the stepped screw of the wood stove 100 to limit the freedom of the multifunctional accessory in the front-back direction and the left-right direction, so as to achieve the purpose of quick installation. The positioning mechanism 141 also includes a bending part 1412 that cooperates with the upper end surface of the wood stove 100. The smoke collecting box 1 is placed on the wood stove 100 through the bending part 1412. In this embodiment, Figure 1 , Figure 2 As shown, during installation, the bent portion 1412 is clamped on the top of the wood stove 100 to play a limiting role, thereby achieving the purpose of rapid installation.

[0039] As another preferred embodiment of the present invention, the smoke collecting box 1 is located above the wood stove 100, and a receiving space 16 is formed between the bottom of the smoke collecting box 1 and the top of the wood stove 100. A storage platform 17 is formed on the top of the smoke collecting box 1, and the storage platform 17 and the smoke collecting cavity 11 form a heat transfer. Figure 4 As shown, the storage space 16 is equivalent to increasing the cooking space of the wood-burning stove 100, acting as an open oven, and increasing the functionality of the wood-burning stove 100. The storage platform 17 can be used to defrost or heat food, further increasing the functionality of the wood-burning stove 100. In a further embodiment, the top of the smoke collecting box 1 is detachably provided with a stainless steel plate, and the top of the stainless steel plate is provided with a countersunk hole. Figure 2 , Figure 3 As shown, a stainless steel plate is detachably provided on the top of the smoke collecting box 1, and the stainless steel plate is countersunk and connected with countersunk screws to make the top of the smoke collecting box 1 flat. In a further embodiment, the thickness of the stainless steel plate is 3 mm, and the provision of the stainless steel plate makes the multifunctional accessory less likely to deform when heated.

[0040] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
