[0037] According to an optional embodiment of the present invention, the oil-proof layer 7 and the semi-ring oil-proof part 37 are both made of oil-proof cotton, which not only has excellent oil fume barrier ability, but also has a certain adsorption effect, which can slow down the accumulation of oil and dirt, reduce the frequency of cleaning, and improve the overall usage experience.

[0038] According to an optional embodiment of the present invention, the turntable 10 is made of a heat-insulating material, and a heat dissipation channel is provided on the turntable 10 , and the heat dissipation channel is used to dissipate heat from the refrigeration fins 12 .

[0039] According to an optional embodiment of the present invention, the noise reduction component is sound insulation cotton, which effectively suppresses the noise of motor operation and improves the user's kitchen comfort.

[0040] Implementation process:

[0041] When the motor body 1 stops, the bevel gear 2 30 and the bevel gear 1 24 are engaged.

[0042] When the motor body 1 is turned on, the output shaft 2 first rotates slowly and then gradually accelerates. When the output shaft 2 rotates slowly, the copper bar 27 will not heat up, and the bevel gear 2 30 remains engaged with the bevel gear 1 24. The output shaft 2 drives the bevel gear 1 24, the bevel gear 2 30, the rotating rod 1 31, the rotating rod 2 32, and the transmission member 34 to rotate. The transmission member 34 pushes the pressure piece 41 to move left. The pressure piece 41 moves back and forth left and right under the combined action of the thrust of the transmission member 34 and the reset elastic force of the return spring 42. The pressure piece 41 squeezes and vibrates the hose 22, so that the oil stains in the hose 22 are shaken off into the oil filling box 35. When the pressure piece 41 moves to the left limit position, the channel in the hose 22 will not be completely closed.

[0043] When bevel gear 1 24 rotates rapidly, all magnets 25 pass by the left side of copper bar 27 one by one, thereby generating eddy current in copper bar 27 and heating copper bar 27. The heat of copper bar 27 is transferred to thermal expansion member 28, causing thermal expansion member 28 to expand and elongate. Thermal expansion member 28 pushes slide plate 29 to overcome the elastic force of support spring 44 and move downward. Bevel gear 2 30 moves downward and disengages from bevel gear 1 24, thereby pausing transmission member 34 to push pressing member 41. Pressing member 41 stops squeezing hose 22, thereby extending the service life of hose 22 and making it easier for oil droplets to pass through hose 22.

[0044] The output shaft 2 drives the turntable 10 to rotate. During the rotation of the turntable 10, the two conductive rings 14 respectively maintain contact with the two conductive balls 19. The power supply supplies power to the refrigeration plate 12. The cold surface of the refrigeration plate 12 transfers the cold energy to the cooling strip 11 to cool the cooling strip 11. The hot surface of the refrigeration plate 12 can dissipate heat through the heat dissipation channel. After the oil smoke enters the barrel channel 5 and encounters the cooling strip 11 with a lower temperature, it is cooled and solidified into oil droplets. The oil droplets are thrown to the inner wall of the annular groove 20 by the centrifugal force of the cooling strip 11. The oil droplets are discharged along the annular groove 20. The oil fume is collected from the oil container 35 through the inner wall of the cooling strip 11 and then falls from the hose 22 to the oil box 35 for collection. The two semi-ring oil-proof parts 37 can prevent a small amount of oil fume passing through the cooling strip 11 from entering the motor body 1 through the gap between the inner wall of the shaft hole on the motor body 1 and the output shaft 2. The rotation of the cooling strip 11 can not only increase the contact area with the oil fume, but also make the oil separate from the cooling strip 11 for recycling, thereby blocking most of the oil fume, reducing the oil attached to the semi-ring oil-proof parts 37, and extending the service life of the semi-ring oil-proof parts 37.

[0045] After the motor body 1 is shut down, the copper bar 27 gradually cools and shrinks, and the slide plate 29 moves upward and resets under the elastic force of the support spring 44, and the bevel gear 2 30 re-engages with the bevel gear 1 24, so that the pressure piece 41 can squeeze the hose 22 when the motor body 1 is started next time to prevent the oil stain in the hose 22 from being blocked.

[0046] When the semi-ring oil-proof part 37 needs to be replaced, turning the handle 23 can drive the two threaded rods 9 to rotate. Since the thread directions of the two threaded rods 9 are opposite, the two extension blocks 38 will move away from each other, thereby moving the two semi-ring covers 6 away, and the two semi-ring oil-proof parts 37 are moved to the outside of the treatment cylinder 3, so that the user can replace the semi-ring oil-proof parts 37.

[0047] The provision of the oil-proof layer 7 can prevent oil smoke from entering through the gap between the treatment cylinder 3 and other components, causing excessive oil smoke to contact the semi-ring oil-proof member 37 .

[0048] The present invention has the following beneficial effects:

[0049] The cooling strips 11 provided on the turntable 10 cooperate with the refrigeration fins 12 to achieve rapid condensation of the oil smoke entering the cylinder channel 5. The condensed oil droplets are thrown into the annular groove 20 under the centrifugal action of the cooling strips 11 and then flow into the oil box 35 through the hose 22, achieving efficient separation and recovery of the oil smoke, and significantly reducing the erosion of the internal structure of the motor body 1 by the oil smoke.

[0050] The extrusion assembly composed of the second rotating rod 32, the transmission member 34, the pressure member 41 and the return spring 42 drives the pressure member 41 to reciprocate during the low-speed cruising operation stage, effectively shaking off the oil stains on the inner wall of the hose 22, preventing the accumulation of oil stains and clogging, extending the service life of the pipeline, and ensuring the long-term stable operation of the equipment;

[0051] A bevel gear 1 24, a magnet 25, a copper bar 27 and a thermal expansion member 28 are provided. The slide 29 is driven to move by the principle of magnetic eddy current heating to achieve automatic switching control of the extrusion assembly. The structure is ingenious and no additional electric components are required to drive the movement of the bevel gear 2 30.

[0052] The power supply sliding connection structure composed of the conductive ring 14, the conductive ball 19, the conductive sheet 16, the conductive block 18 and other components keeps the cooling sheet 12 powered during the rotation of the turntable 10, ensuring the continuous low temperature state of the cooling strip 11 and improving the efficiency of oil fume condensation.

[0053] By providing structures such as a semi-ring cover 6, an oil-proof layer 7, a connecting handle 36 and a semi-ring oil-proof part 37, and cooperating with an adjustable threaded rod 9 and a turning handle 23, the semi-ring oil-proof part 37 can be quickly disassembled and assembled, making it convenient for users to replace and maintain it regularly. At the same time, a sealing structure is formed between the semi-ring oil-proof part 37 and the motor body 1, further enhancing the ability to resist oil smoke penetration.

[0054] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
