[0022] As shown in Figure 1 The gas stove smoke recovery system shown in FIG. 4 comprises a cooking bench device 1, the upper end of which is fixedly connected with a gas stove pot ring 2, the rear end of the cooking bench device 1 is fixedly connected with the gas stove pot ring 2, which is in communication with a flow guide pipe 3, the end of the flow guide pipe 3 away from the cooking bench device 1 is fixedly connected with a smoke recovery bin 4, the inner end of the smoke recovery bin 4 is fixedly connected with an annular water conveying pipe 6, the inner end of the smoke recovery bin 4 is fixedly connected with a central shaft vertical rod 7, the central shaft vertical rod 7 is externally connected with a motor, the outer end of the central shaft vertical rod 7 is fixedly connected with a plurality of ring-shaped sleeve shafts 17, the outer left and right sides of the ring-shaped sleeve shafts 17 are fixedly connected with disturbance vanes 8, and the inner end of the disturbance vanes 8 is provided with a horizontal slot 11.
[0023] The right side of the smoke recovery bin 4 is fixedly connected with a liquid outlet guide pipe 5 in communication with the annular water conveying pipe 6, and the upper end of the horizontal slot 11 is provided with a set of movable hinges 10.
[0024] The lower end of the movable hinge 10 is hingedly connected with a follower vane 12, and the end of the plurality of vertically arranged disturbance vanes 8 away from the central shaft vertical rod 7 is fixedly connected with a magnetic vertical rod 9.
[0025] The inner end of the annular water conveying pipe 6 is fixedly connected with a plurality of internal layers 13, which are equidistantly spaced apart.
[0026] The inner side wall of the plurality of internal layers 13 away from the central vertical rod 7 is fixedly connected with springs 14, one end of each spring 14 close to the central vertical rod 7 is fixedly connected with a metal surface layer movable inner sphere 15.
[0027] The outer end of the metal surface layer movable inner sphere 15 is fixedly connected with a plurality of silica gel sharp corner rods 16, which are uniformly distributed.
[0028] The magnetic force vertical rod 9 and the metal surface layer movable inner sphere 15 are magnetically matched with each other, and the inner end of the annular water conveying pipe 6 penetrates water.
[0029] When the gas stove smoke recovery system is running, the high-temperature flue gas generated by the gas combustion on the cooking bench device 1 is transported to the smoke recovery bin 4 through the flow guide pipe 3 under the action of natural convection and system design. The water in the annular water conveying pipe 6 is pre-filled with water. The high-temperature flue gas entering the smoke recovery bin 4 contacts the outer wall of the annular water conveying pipe 6. Based on the principle of heat transfer, the heat in the flue gas is transferred to the water in the annular water conveying pipe 6, causing the water temperature to rise. The heated water flows out through the liquid outlet pipe 5 connected to the annular water conveying pipe 6 and can be used as domestic hot water for secondary use, realizing flue gas waste heat recovery. At the same time, the external motor drives the middle shaft vertical rod 7 to rotate, and the middle shaft vertical rod 7 drives the ring-shaped sleeve shaft 17 fixed to the outer end thereof to rotate synchronously, and the ring-shaped sleeve shaft 17 further drives the disturbance fan blade 8 to move in a circular motion around the axis of the middle shaft vertical rod 7. During the rotation of the disturbance fan blade 8, the flue gas in the smoke recovery bin 4 is stirred, the flow path and direction of the flue gas are changed, the contact range between the flue gas and the annular water conveying pipe 6 is increased, and the heat exchange efficiency between them is improved. Under the action of the flue gas flow, the driven fan blade 12 in the horizontal slot 11 at the inner end of the disturbance fan blade 8 swings around the movable hinge 10 as a fulcrum. The swing of the driven fan blade 12 disturbs the flow state of the flue gas, further enhances the turbulence degree of the flue gas, makes the distribution of the flue gas in the smoke recovery bin 4 more uniform, and the contact between the flue gas and the annular water conveying pipe 6 more sufficient, and strengthens the heat exchange process. In addition, due to the magnetic attraction between the magnetic vertical rod 9 and the metal surface layer movable inner ball 15, when the disturbance fan blade 8 rotates, the magnetic vertical rod 9 moves with it, and the magnetic field generated thereby acts on the metal surface layer movable inner ball 15. Under the action of the magnetic force, the metal surface layer movable inner ball 15 overcomes the elastic force of the spring 14 and moves back and forth in the annular water conveying pipe 6. The silica gel sharp corner rod 16 at the outer end of the metal surface layer movable inner ball 15 disturbs the water in the annular water conveying pipe 6 during the movement, breaks the laminar flow state of the water, improves the mixing degree of the water, and makes the heat exchange between the water and the inner wall of the annular water conveying pipe 6 more efficient. Moreover, the reciprocating impact of the metal surface layer movable inner ball 15 can prevent scale deposition on the inner wall of the annular water conveying pipe 6, ensuring continuous and efficient heat exchange.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not exist, they should be considered as falling within the scope of the present disclosure.

Any appropriate changes and variations to the above embodiments within the spirit and principles of the present application shall fall within the scope of the present application.
