By using the cooperation between the first motor and the fan blades, the air flow can be driven when the fan blades rotate to achieve ventilation inside the ship's kitchen.

[0013] Preferably, the first motor matches the shape of the inner wall of the protective cover, the protective cover is made of aluminum alloy, and the outer wall of the protective cover has heat dissipation fins distributed in a ring array.

[0014] The above technical solution utilizes an aluminum alloy protective cover, which has good thermal conductivity and can absorb the heat generated by the first motor. In addition, the design of the heat dissipation fins can carry away the heat when the airflow flows inside the duct, thus preventing the first motor from overheating.

Two sets of filters are provided, and the pore size of the two sets of filters decreases from left to right. The upper end of the collection box is connected to the inside of the sleeve.

[0016] By adopting the above technical solution, the combination of the sleeve and the filter can adsorb the oil carried in the air, and the two sets of filter screens with different pore sizes can reduce the probability of clogging and maintain the ventilation and filtration effect.

[0017] Preferably, the scraper is fitted to the left side of the filter screen, and the upper ends of the air duct and the sleeve are both provided with movable grooves. The upper end of the scraper passes through the movable grooves. The upper left end of the air duct is covered with a sealing cover. A transmission plate is movably connected inside the sealing cover, and the lower end of the transmission plate is connected to the scraper. A second motor is fixed to the front end of the sealing cover, and a reciprocating screw is connected to the rear end of the second motor. The rear end of the reciprocating screw extends into the interior of the sealing cover, and the reciprocating screw is connected to the transmission plate.

[0018] Using the above technical solution, the second motor can drive the reciprocating screw to rotate. By cooperating with the transmission plate, the scraper can be driven to reciprocate. During the reciprocating motion, the oil stains attached to the filter screen surface are scraped and cleaned, maintaining the air passage efficiency of the filter screen and avoiding clogging.

A positioning frame 5 is fixed inside the air duct 1, and a protective cover 6 is installed on the right side of the positioning frame 5. A first motor 7 is installed inside the protective cover 6, and a fan blade 8 is connected to the left side of the first motor 7. The left side of the air duct 1 is inclined, and the air duct 1 is engaged with the protective net 2. The air duct 1 and the guide pipe 4 are sealed together, and the guide pipe 4 is used for air filtration. Pipe 4 has a tapered design; positioning frame 5 has a cross-shaped design and is fixed to protective cover 6. The left shaft end of the first motor 7 passes through positioning frame 5 and connects to fan blade 8; the shape of the first motor 7 matches the inner wall of protective cover 6, and protective cover 6 is made of aluminum alloy, with heat dissipation fins distributed in a ring array on the outer wall of protective cover 6; a complete ventilation structure is formed by air duct 1, guide shroud 3, and guide pipe 4. Air duct 1 has a square multi-segment structure design, and adjacent air ducts 1 are connected by bolts and designed with rubber sealing rings to prevent air leakage. Smoke enters the interior from the left side of air duct 1. The left end of air duct 1 is designed with an incline to facilitate the flow of smoke, and a protective net 2 is designed to prevent debris from entering. When operating, the first motor 7 is started, and the first motor 7 drives the fan blade 8 to rotate. When the fan blade 8 rotates, it drives the flue gas to flow inside the air duct 1. Because the first motor 7 is covered with a protective cover 6, the aluminum alloy protective cover 6 can transfer heat, and together with the external array of heat dissipation fins, it can improve the heat dissipation effect of the first motor 7 and avoid high temperature during long-term use.

[0032] A sleeve 9 is installed inside the left side of the air duct 1, and a filter screen 10 is installed inside the sleeve 9. A scraper 12 is installed on the side of the filter screen 10, and a collection box 11 is installed at the bottom left side of the air duct 1. The sleeve 9 is fixed inside the air duct 1, and the inner wall of the sleeve 9 is connected to the filter screen 10. There are two sets of filters 10, and the aperture of the two sets of filters 10 decreases from left to right. The upper end of the collection box 11 is connected to the inside of the sleeve 9. The design of the sleeve 9 allows the filter screen 10 to be installed. The two sets of filters 10 with decreasing apertures can filter and intercept oil in sequence, preventing oil from adhering to the blade structure and maintaining stable ventilation. At the same time, the oil residue on the filter screen 10 can flow downward to the inside of the collection box 11 to collect the oil.

[0033] The scraper 12 is fitted to the left side of the filter 10. Movable grooves are provided at the upper ends of both the duct 1 and the sleeve 9.

The rear end of the reciprocating screw 14 extends into the sealing cover and is connected to the transmission plate 13. The scraper 12 structure... The design is capable of scraping and cleaning oil stains on the outside of the filter screen 10. Since oil stains have relatively poor fluidity, this design avoids affecting the airflow of the filter screen 10. When the ventilation device is in operation, the second motor 15 can drive the reciprocating screw 14 to rotate. The reciprocating screw 14 cooperates with the transmission plate 13, and the transmission plate 13 drives the scraper 12 to reciprocate. When the scraper 12 reciprocates, it can scrape off the oil stains on the surface of the filter screen 10. The scraped oil stains can fall into the collection box 11 for subsequent processing.
