[0006] Compared with the prior art, the cage-type range hood of the utility model configures a ventilation structure for the range hood body, and arranges a plurality of fresh air outlets on the front side and left and right sides of the range hood body surrounding the smoking port, so that the fume suction device discharges the indoor fume to the outside, while the fresh air suction device sucks in the fresh air from the outside and discharges it through the plurality of fresh air outlets, thereby forming a better indoor and outdoor air flow exchange and allowing the discharged fresh air flow to form a wind curtain surrounding the lower periphery of the range hood body to shield the fume from being discharged outward, thereby effectively preventing the escape of fume, creating a good kitchen environment, and fully protecting the health of cooks.

[0007] Furthermore, several of the fresh air outlets are arranged at the bottom edge of the range hood body, and the fresh air outlets are strip-shaped holes, and the length direction of the fresh air outlets is arranged corresponding to the edge direction of the range hood body; through such an arrangement, the exhausted fresh air flow forms a tighter wind curtain, which has a better effect in shielding oil fumes.

[0008] Furthermore, fresh air supply ports are respectively provided on both sides of the top of the range hood body; through such an arrangement, part of the fresh air flow can be discharged from the top of the range hood body into the room, balancing the indoor air pressure and making the kitchen air cleaner.

[0009] Furthermore, the range hood body is provided with a fresh air cavity and an oil fume cavity which are separately arranged, the fresh air cavity is arranged around the outside of the oil fume cavity, the fresh air cavity is respectively connected to the fresh air outlet and the fresh air channel, and the oil fume cavity is respectively connected to the smoke outlet and the oil fume channel; through such an arrangement, the oil fume airflow discharged from the range hood and the incoming fresh air airflow are isolated from each other, thereby preventing the oil fume airflow from flowing back into the room.

[0010] Furthermore, the ventilation structure is located on the top of the range hood body, the fresh air channel and the oil fume channel are arranged side by side on the upper side of the smoke outlet, the oil fume air cavity is L-shaped, and the smoke outlet is connected to the oil fume channel through the L-shaped oil fume air cavity; through such an arrangement, the oil fume airflow entering through the smoke outlet is effectively discharged outward from the oil fume channel.

[0011] Furthermore, the fresh air suction device and the oil fume suction device are centrifugal fans respectively; through such an arrangement, the centrifugal fan has the advantages of reducing energy consumption and cost, and the ventilation effect is better.

[0012] Furthermore, the smoking port is provided with an oil fume net, the mesh holes of which form a smoking hole. By such an arrangement, the oil fume in the oil fume airflow can be filtered through the oil fume net and collected in the oil collecting tank, thereby reducing air pollution.

[0013] Furthermore, a detachable oil collecting groove is provided at the bottom of the rear side of the range hood body, and an oil outlet hole connecting the oil fume cavity and the oil collecting groove is provided at the bottom of the rear side of the range hood body; through such an arrangement, the oil in the range hood body can be effectively collected, making it convenient for users to clean.
