A spring 214 is fixedly connected between the third connecting block 211 and the fourth connecting block 212. A handle 30 is fixedly connected to the outer wall of one side of the protective door 201. In the specific use process, when the protective door 201 is in the closed state and the spring 214 is in the initial state, the handle 30 is pulled to drive the sliding block 206 on the protective door 201 to start sliding along the path of the sliding groove 204. Since the sliding groove 204 is arranged on the rotating block 203, and the rotating block 203 is connected with the main shell 10 through the hinge, as the sliding block 206 slides, the rotating block 203 also rotates around the axis of the hinge. As the protective door 201 is opened, the second connecting block 210 drives the connecting rod 213 to make the first connecting block 209 rotate around the first fixed shaft 207 as the axis. At this time, the rotation of the first connecting block 209 drives the fourth connecting block 212 to rotate around the first fixed shaft 207. Since the fourth connecting block 212 is connected with the third connecting block 211 through the spring 214, the movement of the fourth connecting block 212 will cause the spring 214 to be stretched until the protective door 201 is completely opened. When the protective door 201 is completely opened, it will be attached to the side of the outer wall of the main shell 10, without occupying too much space. When the user needs to close the protective door 201, he can hold the handle 30 and push it inward. The spring 214 will provide assistance for the closing of the protective door 201, making the closing process of the protective door 201 more smooth.
[0039] Working principle: start turbine blower 102 to produce suction, oil fume is inhaled into the smoke collecting cavity 13 in the smoke collecting hood 12 by the suction of the turbine blower 102, the oil droplets and particulate matters in the oil fume are intercepted by the oil fume separation net 16, and fall into the oil collecting box 17 through the oil collecting groove 15, after the filtration of the oil fume separation net 16, the relatively pure air continues to flow to the turbine blower 102, the turbine blower 102 inhales the air into the inner cavity 11, and finally discharges the exhaust pipe 103 through the exhaust end of the turbine blower 102, the check valve 40 prevents the odor from flowing back into the kitchen, ensures the indoor air quality, the user can periodically take out the oil collecting box 17 from the sliding groove 19, and clean or replace it, the two oil fume separation nets 16 are fixed by screws, stable and easy to disassemble and clean, when the turbine blower 102 needs to be disassembled and cleaned, the power is turned off, the protective door 201 is in the closed state and the spring 214 is in the initial state, the handle 30 is pulled to drive the sliding block 206 on the protective door 201 to start sliding along the path of the sliding groove 204, since the sliding groove 204 is opened on the rotating block 203, and the rotating block 203 is connected with the main shell 10 through the hinge, therefore, with the sliding of the sliding block 206, the rotating block 203 also rotates around the axis of the hinge, with the opening of the protective door 201, the second connecting block 210 drives the connecting rod 213 to make the first connecting block 209 rotate around the first fixed shaft 207, at this time, the rotation of the first connecting block 209 drives the fourth connecting block 212 to rotate around the first fixed shaft 207, since the fourth connecting block 212 is connected with the third connecting block 211 through the spring 214, therefore, the movement of the fourth connecting block 212 will cause the spring 214 to be stretched, until the protective door 201 is completely opened, the protective door 201 will be attached to one side of the outer wall of the main shell 10 when it is completely opened, and will not occupy too much space, so as to clean the turbine blower 102 in the inner cavity 11, when the turbine blower 102 is cleaned, hold the handle 30 and push it inward, the spring 214 will provide power for the closing of the protective door 201, so that the closing process of the protective door 201 is more smooth.
