Disclosure of Invention
In order to overcome the defect that the oil fume flow directly impacts a plasma electric field, the invention provides a preposed fan blade which is arranged at the airflow inlet of a plasma electric field of a purifier and is unpowered, the fan blade is driven to rotate by the suction force of a fan of a synthetic stove, a water retaining strip is arranged on the wind cutting surface of the fan blade, and the fan blade can be adhered with water vapor and large-particle dust in the oil fume flow when rotating, so that the airflow is prevented from directly impacting the electric field of a plasma purification device, and the oil fume removing effect of the synthetic stove is improved.
The technical measures adopted for solving the technical problems are that the fan blade comprises a fan blade main body, a shaft cylinder, a bearing, blades, a water retaining strip, a storage disc and a liquid dispensing device, wherein the fan blade main body comprises the shaft cylinder and the blades, and the bearings are arranged at two ends of the shaft cylinder; the water retaining strip is inclined towards the direction of the blade root and is used for preventing oil and water condensed on the blade surface from being thrown out from the blade tip and guiding the oil and water to flow downwards from the root of the water retaining strip; the fan blade main body is arranged on the shells on the two sides of the airflow inlet of the plasma electric field of the purifier through bearings on the two ends, so that the fan blade is positioned at the airflow inlet of the plasma electric field of the purifier. And the mounting positions of the bearings at the two ends are high at the left and low at the right, so that the fan blade is in an inclined posture at the airflow inlet of the plasma electric field. Therefore, the oil water condensed on the blades can flow out to the lower part of the blades conveniently, and the oil water can carry away the dust adhered on the blades while flowing through; the storage disc is arranged below the fan blade main body and can be used for receiving oil water and dust flowing out of the lower portion of the fan blade, and a door is opened on the shell corresponding to the fan blade, so that the fan blade can be conveniently taken out of the shell for maintenance and cleaning; the utility model discloses a fan blade, including the fan blade, point liquid device, valve switch-on control switch, the upper end of valve, the valve is installed in the left top of fan blade main part, the axis of the export alignment fan blade of point liquid device, pour into the cleaning solution in the point liquid device, the cleaning solution passes through the valve and drips at the upper end of fan blade, the optional solenoid valve of valve, valve switch-on control switch, when the cleaning solution liquid drop is on the blade, catalysis oil dirt flows downwards together with the oil dirt mixture, cleans the blade at the in-process that flows, and oil water mixture carries the miscellaneous dirt that adheres on the blade at last and flows into the intake disc. When the clarifier during operation, under the suction of fan, install the fan blade of clarifier sunction inlet rotatory under the drive of air current, wrap up in the miscellaneous dirt of holding in the air current and can adhere on the clean mucus of blade, surface temperature can be than inspiratory air current temperature will be low when the fan blade is rotatory, consequently wrap up in the aqueous vapor of holding in the air current and touch cold blade and can condense on the blade, water smoke can mix with the oil dirt after condensing into water on the blade and flow in the storage disc to avoid oil smoke and aqueous vapor direct impact plasma purifier's electric field, improved the mesh that removes the oil smoke in the synthetic kitchen.
The plasma purification device has the beneficial effects that the device can be used for pretreating the dust and the water vapor wrapped in the oil smoke, so that the oil smoke and the water vapor are prevented from directly impacting an electric field of the plasma purification device, and the structure is reasonable.
