[0009] In an improved solution, the tube wall of the hose is corrugated, thereby ensuring that the hose has a certain degree of elasticity, is easier to bend and is not easily damaged.
[0010] In an improved solution, a spoke plate is provided on the inner ring side of the receiving ring, and the spoke plate can play a role in guiding flow and improving the structural strength of the receiving ring.
[0011] In an improved solution, the spoke plates are arranged radially from the center of the receiving ring and connected to the inner circumferential wall of the receiving ring, thereby ensuring that the smoke passes through the spoke plates more smoothly on the one hand, and on the other hand, the spoke plates using this structure can achieve effective support for the receiving ring.
[0012] In an improved solution, the outer peripheral wall of the receiving ring is provided with barrier ribs along the circumferential direction, and the barrier ribs are located in the axial middle part of the receiving ring. The adapter and the smoke pipe are both sleeved on the corresponding receiving ring.
[0013] In an improved solution, there are at least two smoke tubes, and adjacent smoke tubes are connected via a receiving ring, so that a corresponding number of smoke tubes can be selected for splicing according to the required total length.
[0014] In an improved solution, a check valve is provided at the smoke outlet of the smoke pipe at the farthest end relative to the air outlet hood to prevent smoke from flowing back.
[0015] In an improved solution, the length of the smoke pipe is 200-600 mm, so as to adapt to most usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0026] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] See also Figure 1-Figure 5A combined smoke duct provided in an embodiment of the utility model comprises an air outlet hood 1, a telescopic tube 2, a smoke duct 3 and a receiving ring 4. The air outlet hood 1 is provided with a smoke inlet 11 and a smoke outlet 12 which are interconnected. Both ends of the smoke duct 3 are provided with a smoke inlet 31 and a smoke outlet 32 respectively. The telescopic tube 2 comprises a hose 21 and adapters 22 connected to both ends of the hose 21. One of the two adapters 22 is connected to the smoke outlet 12, and the other is connected to the smoke outlet 32 of the smoke duct 3 through the receiving ring 4.
[0028] In the above scheme, the smoke inlet 11 of the air outlet hood 1 is used to connect to the outlet of the range fumes extracting appliance, and the smoke outlet 12 is connected to the telescopic tube 2, and the smoke at the outlet of the range fumes extracting appliance enters the smoke duct 3 through the outlet hood and the telescopic tube 2 and is discharged; compared with the prior art, the above scheme adds a telescopic tube 2 between the air outlet hood 1 and the smoke duct 3. Since the middle part of the telescopic tube 2 is a hose 21, it can be freely bent according to the required corner angle, and the assembly is flexible and not easy to be damaged; at the same time, by adding a receiving ring 4 to connect the telescopic tube 2 and the smoke duct 3, the connection stability between the two can be effectively improved.
[0029] In this embodiment, the adapter 22 is made of a hard material, such as stainless steel; the adapter 22 and the hose 21 are connected by a buckle structure, and the connection between the adapter 22 made of hard material and the air outlet hood 1 is more stable. At the same time, the other adapter 22 and the hose 21 are connected by the buckle structure, and the sealing is better. More specifically, in this embodiment, the adapter 22 and the hose 21 are connected by the buckle structure, which means that: the outer peripheral wall of the adapter 22 on the side close to the hose 21 is provided with an embedding groove 221 and an inner groove 222 along the circumferential direction, and the inner groove 222 is located at the bottom of the embedding groove 221 away from the hose 21; the side of the hose 21 close to the adapter 22 is provided with an embedding ring 211 for being snapped into the embedding groove 221, and the inner peripheral wall of the embedding ring 211 is provided with a convex ring 212 for being snapped into the inner groove 222 along the circumferential direction, so that the sealing is effectively ensured by the snap fit between the embedding groove 221 and the embedding ring 211 and the snap fit between the inner groove 222 and the convex ring 212. Of course, in other embodiments, the buckle structure between the adapter 22 and the hose 21 may also be in other forms in the prior art, and the present design does not limit this.
[0030] In this embodiment, the cross-sections of the smoke outlet 12, the telescopic tube 2, the smoke pipe 3 and the receiving ring 4 of the air outlet hood 1 are preferably oval, and of course they can be other shapes such as circular as required. The tube wall of the hose 21 is preferably corrugated to ensure that the hose 21 has a certain degree of elasticity, is easier to bend and is not easy to be damaged.
[0031] As an improvement to the receiving ring 4, a radial plate 41 is provided on the inner ring side of the receiving ring 4, and the radial plate 41 can play a role in guiding flow and improving the structural strength of the receiving ring 4. More specifically, in this embodiment, the radial plates 41 are arranged radially from the center of the receiving ring 4 and connected to the inner peripheral wall of the receiving ring 4, so as to ensure that the smoke passes through the radial plates 41 more smoothly on the one hand, and on the other hand, the radial plates 41 with this structure can effectively support the receiving ring 4.
[0032] It should be noted that in the present embodiment, the adapter 22 and the smoke pipe 3 are both sleeved on the outside of the corresponding receiving ring 4. In order to improve the accuracy and stability of the sleeved position of the adapter 22 and the smoke pipe 3 relative to the receiving ring 4, the outer wall of the receiving ring 4 is provided with a barrier rib 42 along the circumferential direction. The barrier rib 42 is located in the axial middle part of the receiving ring 4. The barrier rib 42 is used for abutment and positioning of the adapter 22 and the smoke pipe 3 sleeved on the outside of the receiving ring 4.
[0033] The number of smoke tubes 3 can be increased or decreased as needed. For example, in this embodiment, the number of smoke tubes 3 is two, and adjacent smoke tubes 3 are connected by receiving rings 4, so that a corresponding number of smoke tubes 3 can be selected for splicing according to the required total length. The length of the smoke tube 3 is preferably 200 to 600 mm, so as to adapt to most usage scenarios.
[0034] As an improvement to the present embodiment, a check valve 5 is provided at the smoke outlet 32 of the smoke pipe 3 at the farthest end relative to the air outlet cover 1, so as to prevent smoke from flowing back.
