Description

Technical Field

[0001] The utility model relates to the technical field of oil fume purification, in particular to an oil fume purification device. Background Art

[0002] Oil fume is an aerosol composed of tiny oil droplets, water vapor, fuel decomposition products and other substances produced during the cooking or production process. When this substance diffuses into the atmosphere, it mixes with dust in the air and dust on the ground to form sticky and difficult-to-remove oil stains. Since oil fume contains a variety of harmful substances, such as fine particles, organic matter and toxic gases, long-term exposure to these pollutants may pose a threat to human health, leading to respiratory diseases, cardiovascular problems and other health problems. Therefore, an oil fume purification device is needed to reduce the concentration of these harmful substances and protect people's health.

[0003] According to the search, Chinese patent literature, announcement number: CN208553472U, discloses a fume purification device, which decomposes and filters organic matter in fume air through a decomposition chamber, and the fume air treated by the decomposition chamber enters the ionization chamber through an excessive diameter change, and the ionization chamber ionizes the air in the fume air through a high-voltage plasma electric field, so that the particles and oil particles in the air are charged, and then the charged particles and oil particles are removed, further achieving air purification, and finally discharged through the outlet diameter change, outlet pipe and outlet. However, after long-term use, a large amount of oil stains accumulate in the filter screen and the inside of the ionization chamber of the device and cannot be effectively cleaned, which will reduce the purification efficiency of the device and affect the health of the user.

After that, the water flows into the interior of the oil collecting pipe with oil stains and the like, and the sealing baffle is opened at the same time, so that the waste water can be discharged, so that the cleaning of the inside of the device can be effectively completed, thereby improving the overall purification efficiency and service life.

[0016] Preferably, there are multiple nozzles, and the multiple nozzles are evenly distributed on the outer side of the water spray pipe.

[0017] Through the above technical solution, multiple nozzles can effectively spray out the water flow inside the water spray pipe, and the water spray pipe can also drive the multiple nozzles to rotate together, thereby achieving comprehensive cleaning of parts such as the first electrode plate, thereby improving the overall cleaning efficiency of the device.
