[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0026] First embodiment: Figure 1-Figure 4 As shown, a smoke exhaust device of an integrated wood-fired stove is provided, comprising a machine body 1 and a wood-fired stove 2 arranged on the machine body 1, the wood-fired stove 2 is provided with a smoke exhaust structure 3 for independently exhausting the smoke generated by it to the outside, the smoke exhaust structure 3 comprises a smoke exhaust pipe 301, the wood-fired stove 2 is provided with a smoke outlet 201, the smoke inlet end of the smoke exhaust pipe 301 is connected to the smoke outlet 201, and the smoke outlet end of the smoke exhaust pipe 301 is arranged on the side and / or rear of the machine body 1.

[0027] Specifically, the exhaust structure 3 separately arranged on the wood stove 2 enables the smoke generated by the wood stove to be independently discharged through the exhaust structure 3, thereby achieving isolation from other parts of the machine body; the smoke inlet end of the smoke exhaust pipe 301 is connected to the smoke outlet 201 on the wood stove 2, ensuring that the smoke generated by the wood stove 2 can smoothly enter the smoke exhaust pipe 301, and the smoke outlet end of the smoke exhaust pipe 301 is arranged on the side and / or rear of the machine body 1, which is conducive to guiding the smoke to the outdoors or other ventilation areas; it effectively solves the problem of the smoke of the wood stove 2 being discharged to the outside through the range hood in the prior art, prevents the high-temperature smoke from damaging the range hood and the machine body, and improves the safety and reliability of the use of the integrated wood stove.

[0028] Furthermore, the connection between the smoke inlet end of the smoke exhaust pipe 301 and the smoke outlet 201 can be connected by means of a sealant or a sealing gasket, which can further prevent smoke leakage.

[0029] Further, if Figure 2-Figure 4 As shown, the smoke exhaust pipe 301 includes a smoke inlet portion 3011 and a smoke outlet portion 3012 . The smoke inlet portion 3011 is vertically arranged and connected to the smoke outlet 201 , and the smoke outlet portion 3012 is horizontally arranged at the side and / or rear of the machine body 1 .

[0030] Specifically, the smoke inlet 3011 is vertically arranged and tightly connected to the smoke outlet 201 of the wood stove 2. The vertical arrangement helps the smoke to naturally flow vertically downward along the smoke inlet 3011, so that the smoke can enter the smoke exhaust pipe 301 more smoothly; at the same time, the tight connection ensures that the smoke will not leak into the interior of the body 1, thereby protecting other components inside the body;

[0031] The smoke outlet 3012 is horizontally disposed on the side and / or rear of the body 1. The horizontally disposed smoke outlet 3012 helps to smoothly guide the smoke to the outside, thereby preventing the smoke from generating eddy currents or backflows inside the body. At the same time, being disposed on the side and / or rear of the body, the smoke can be conveniently discharged to a place far away from the user and other devices, thereby improving the safety of use.

[0032] Further, if Figure 2-Figure 4 As shown, the smoke exhaust pipe 301 also includes a first connecting portion 3013, which includes an inclined section 3013a and a first corner section 3013b, one end of the inclined section 3013a is connected to the smoke inlet portion 3011, and the other end of the inclined section 3013a is connected to one end of the first corner section 3013b.

[0033] Specifically, the inclined section is designed to be connected to the smoke inlet 3011, and its main function is to guide the smoke discharged from the smoke outlet 201 of the wood stove and gradually change its flow direction. The inclined design can reduce the resistance of the smoke flow and avoid sudden turns that cause poor smoke flow or vortex generation; the inclined section 3013a also plays a buffering role, so that the high-temperature smoke has a smooth transition in temperature and flow rate before entering the subsequent pipeline. The first corner section 3013b is located after the inclined section 3013a, and its function is to further turn the smoke guided by the inclined section 3013a to adapt to the direction of the subsequent pipeline (such as the smoke outlet 3012); the corner design takes into account the principles of fluid mechanics to reduce the energy loss and turbulence generation of the smoke at the corners, thereby ensuring the continuity and stability of the smoke flow.

[0034] Further, if Figure 2 and Figure 4 As shown, an inclination angle c is formed between the inclined section 3013a and the first corner section 3013b, and 100°≤c≤180°.

[0035] Specifically, the inclination angle c is designed to optimize the flow performance of the smoke; within the range of 100° to 180°, the resistance of the smoke at the corners is reduced to avoid excessive turbulence and pressure drop, thereby ensuring that the smoke can smoothly pass through the first connecting portion 301.

[0036] Preferably, the inclination angle c is 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 150°, 155°, 160°, 165°, 170°, 175°, or 180°.

[0037] Further, if Figure 2-Figure 4 As shown, the smoke inlet portion 3011, the smoke outlet portion 3012 and the first connecting portion 3013 are connected by arc transition.

[0038] Specifically, the arc transition can provide a smoother streamlined path, reduce the turbulence and vortex generation of the smoke at the pipe connection, and help the smoke pass through the smoke exhaust pipe 301 more smoothly.

[0039] Further, if Figure 4 As shown, a smoke guide structure 4 is provided on the side of the body 1. When the smoke outlet end of the smoke exhaust pipe 301 is arranged on the side of the body 1, the smoke outlet end is connected to the smoke guide structure 4, and the smoke generated by the wood stove 2 is discharged to the outside through the cooperation of the smoke exhaust pipe 301 and the smoke guide structure 4.

[0040] Specifically, the smoke guiding structure 4 is arranged on the side of the body 1, and its main function is to guide and optimize the emission path of the smoke; when the smoke outlet end of the smoke exhaust pipe 301 is arranged on the side of the body 1, it is connected with the smoke guiding structure 4, which can ensure that the smoke is effectively guided to the outside to avoid spreading indoors.

[0041] Further, if Figure 4 As shown, the smoke guide structure 4 includes a smoke guide hood 401, fan blades 402 and a motor 403. The output shaft of the motor 403 is transmission-connected to the fan blades 402. The motor 403 and the fan blades 402 are arranged in the smoke guide hood 401. The input end of the smoke guide hood 401 is connected to the smoke outlet end of the smoke exhaust pipe 301.

[0042] Specifically, the smoke guide hood 401 is the outer shell of the smoke guide structure 4, and its main function is to concentrate and guide the direction of the smoke flow. The input end is connected to the smoke outlet end of the smoke exhaust pipe 301 to ensure that the smoke exhausted from the smoke exhaust pipe can all enter the smoke guide hood 401 and will not leak into the surrounding environment; when the wood stove is working, the generated smoke is discharged through the smoke exhaust pipe 301, and the motor 403 is started, driving the fan blades 402 to rotate at high speed, generating a strong suction force, which quickly draws the smoke in the smoke exhaust pipe 301 into the smoke guide hood 401, and then the smoke is driven by the airflow generated by the fan blades 402 and discharged from the output end of the smoke guide hood 401 to the outside.

[0043] Second embodiment: Figure 5-Figure 7 As shown, the smoke exhaust device of the integrated wood stove is different from the first embodiment in that:

[0044] Further, if Figure 5 and Figure 6 As shown, the smoke inlet 3011 is arranged horizontally and connected to the smoke outlet 201 .

[0045] Specifically, the design of the horizontally arranged smoke inlet portion 3011 improves the adaptability of the smoke exhaust device to different installation environments, especially in places with restricted height.

[0046] Further, if Figure 5-Figure 7 As shown, the smoke exhaust pipe 301 further includes a second connecting portion 3014 , and a first adapter portion 3015 is provided between one end of the second connecting portion 3014 and the smoke inlet portion 3011 . One end of the second connecting portion 3014 is connected to the smoke inlet portion 3011 through the first adapter portion 3015 .

[0047] Specifically, the second connecting portion 3014 mainly functions to connect the smoke inlet portion 3011 and other parts of the smoke exhaust pipe to ensure that the smoke can pass smoothly. Considering that the smoke inlet portion 3011 is arranged horizontally, the second connecting portion 3014 may need to have a certain bending or turning design to adapt to the transition of smoke flow from horizontal to other directions (such as vertical or oblique); the first adapter portion 3015 is located between the second connecting portion 3014 and the smoke inlet portion 3011, and plays a role of connection and transition.

[0048] A sealing structure is provided between the first adapter portion 3015 and the second connecting portion 3014 and the smoke inlet portion 3011 to ensure air tightness of the connection and prevent smoke leakage; the sealing structure includes a sealant or a sealing gasket connection.

[0049] Further, if Figure 5-Figure 7 As shown, the smoke exhaust pipe 301 also includes a connecting portion 3016, one end of which is connected to the smoke outlet portion 3012, and a second adapter portion 3017 is provided between the other end of the connecting portion 3016 and the second connecting portion 3014, and the connecting portion 3016 and the second connecting portion 3014 are connected via the second adapter portion 3017.

[0050] Specifically, through the reasonable design of the connecting portion 3016 and the second adapter portion 3017, the flow path of the smoke from the wood stove to the outside of the smoke exhaust pipe can be further optimized.

[0051] Furthermore, the second connecting portion 3014 , the first connecting portion 3015 , the connecting portion 3016 and the second connecting portion 3017 are in a U shape.

[0052] Other parts not described are the same as those in the first embodiment.
