[0024] Please refer to Figures 1 - 7 , on the basis of the above embodiment, in another embodiment of the present invention, a collecting device for collecting duck oil is provided inside the equipment frame 1.

When the lifting frame 6 moves upward, it drives the connecting rod 164 to move upward. The upward movement of the connecting rod 164 drives the oil guiding plate 163 to swing upward. The oil guiding plate 163 is rotatably installed on the inner wall of the equipment frame 1. The connecting rod 164 is rotatably installed on the surface of the oil guiding plate 163. One end of the connecting rod 164 away from the oil guiding plate 163 is rotatably connected to the lifting frame 6. The dripping grease is guided into the interior of the collecting frame 161 under the action of the oil guiding plate 163. When the lifting frame 6 moves upward, it drives the connecting rod 164 to move upward.

[0025] A scraping rod 165 is slidably installed above the oil guiding plate 163. A telescopic elastic rod 166 is rotatably installed below the fixing plate 162. The free end of the telescopic elastic rod 166 is rotatably connected to the scraping rod 165. The scraping rod 165 slides to push the residual grease above the oil guiding plate 163 into the interior of the collecting frame 161, improving the collection efficiency of the grease, facilitating subsequent centralized treatment, and effectively avoiding the pollution of the smoking environment caused by the residual grease on the surface of the oil guiding plate 163.

[0026] A sliding plate 167 is slidably installed above the lifting frame 6, and a conduction rod 168 is rotatably installed above the sliding plate 167. One end of the conduction rod 168 away from the sliding plate 167 is rotatably connected to the inner wall of the equipment frame 1. The movement of the sliding plate 167 can change the force application point of the lifting frame 6, maintain the stability of the lifting frame 6 during the up and down movement, and reduce the failure rate and subsequent maintenance cost of the equipment during use.

[0027] A scraping device for preventing duck oil from condensing on the outer wall of the heat exchange tube 7 is provided on the surface of the heat exchange tube 7. The scraping device includes a sleeve 171 and a rotating plate 172. The sleeve 171 is rotatably installed on the circumferential surface of the heat exchange tube 7, and the rotating plate 172 is fixedly installed on the surface of the sleeve 171. The rotating plate 172 is in contact with the outer wall of the heat exchange tube 7. The scraping device further includes a third gear block 173, a fourth gear block 174, a fixed rod 175, a knocking rod 176, a knocking block 177 and a pushing rod 178. During the movement of the sliding plate 167, the third gear block 173 is driven to move. The movement of the third gear block 173 drives the fourth gear block 174 to rotate. The rotation of the fourth gear block 174 drives the sleeve 171 to rotate. The rotation of the sleeve 171 drives the rotating plate 172 to rotate. The third gear block 173 is fixedly installed below the sliding plate 167, and the fourth gear block 174 is fixedly installed on the circumferential surface of the sleeve 171. The fixed rod 175 is fixedly installed on the surface of the lifting frame 6. The knocking rod 176 is rotatably installed on the circumferential surface of the fixed rod 175. The knocking block 177 is fixedly installed on the surface of the knocking rod 176. The pushing rod 178 is fixedly installed on the surface of the sliding plate 167. The rotation of the rotating plate 172 can scrape the grease on the surface of the heat exchange tube 7, avoiding the grease solidifying on the surface of the heat exchange tube 7 to form a heat insulation layer during the subsequent cooling process, resulting in blocked heat transfer and thus reducing the heat exchange efficiency.

[0028] The surface of the knocking block 177 is set as an arc surface. The third gear block 173 meshes with the fourth gear block 174. The knocking rod 176 is elastic. The knocking block 177 rotates and contacts and knocks the sleeve 171, causing the grease scraped on the surface of the rotating plate 172 to fall off, improving the collection efficiency of the grease and further avoiding grease residue, reducing the subsequent maintenance cost.

[0029] During the operation of this embodiment: When the duck is being smoked, grease will drip. The dripping grease is guided into the interior of the collection box 161 under the action of the oil guide plate 163. When the lifting frame 6 moves upward, it drives the connecting rod 164 to move upward. The upward movement of the connecting rod 164 drives the oil guide plate 163 to swing upward. The upward swing of the oil guide plate 163 drives the scraping rod 165 to move upward. The upward movement of the scraping rod 165 squeezes the telescopic spring rod 166 and causes it to rotate around the other end. The rotation of the telescopic spring rod 166 drives the scraping rod 165 to slide above the oil guide plate 163. The sliding of the scraping rod 165 pushes the residual grease above the oil guide plate 163 into the interior of the collection box 161, improving the collection efficiency of the grease, facilitating subsequent centralized treatment, and effectively avoiding the pollution of the smoking environment caused by the residual grease on the surface of the oil guide plate 163, which may affect the smoking effect of other ingredients, or even cause peculiar smells, reducing the subsequent maintenance cost. At the same time, when the lifting frame 6 moves upward, it drives the sliding plate 167 to move upward. When the sliding plate 167 moves upward, it moves away from the support plate 9 under the action of the conduction rod 168. The movement of the sliding plate 167 can change the force application point of the lifting frame 6, maintaining the stability of the lifting frame 6 during the up and down movement, reducing the failure rate of the equipment during use and the subsequent maintenance cost.

[0030] During the movement of the sliding plate 167, it drives the third gear block 173 to move. The movement of the third gear block 173 drives the fourth gear block 174 to rotate. The rotation of the fourth gear block 174 drives the sleeve 171 to rotate. The rotation of the sleeve 171 drives the rotating plate 172 to rotate. The rotation of the rotating plate 172 can scrape the grease on the surface of the heat exchange tube 7, preventing the grease from solidifying on the surface of the heat exchange tube 7 to form a heat insulation layer during the subsequent cooling process, which may cause the heat transfer to be blocked, thereby reducing the heat exchange efficiency. At the same time, it avoids the breeding of bacteria caused by the residual grease, effectively improving the heat exchange efficiency of the equipment and reducing the subsequent maintenance cost. At the same time, the movement of the sliding plate 167 drives the push rod 178 to move. The movement of the push rod 178 contacts and drives the knocking rod 176 to rotate. The rotation of the knocking rod 176 drives the knocking block 177 to rotate. The rotation of the knocking block 177 contacts and knocks the sleeve 171, causing the grease scraped from the surface of the rotating plate 172 to fall off, improving the collection efficiency of the grease, and further avoiding the residual grease, reducing the subsequent maintenance cost.
