[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 7 As shown, the utility model provides an oil fume purifier, comprising a housing 1, an air inlet 2 and an air outlet 3 are respectively arranged at the left and right ends of the housing 1, and a filter plate 4 is installed on the inner wall of the housing 1 and at positions adjacent to the air inlet 2 and the air outlet 3;

[0022] The two filter plates 4 respectively perform physical pre-purification filtration and post-purification filtration on the oil smoke entering the purifier;

[0023] A set of axial flow fans 21 are installed inside the air inlet end 2 and the air outlet end 3, and flange connection surfaces are provided on the end surfaces of the air inlet end 2 and the air outlet end 3;

[0024] The axial flow fan 21 at the air inlet end 2 is used to send smoke into the interior of the oil fume purifier, and the axial flow fan 21 at the air outlet end 3 is used to discharge the purified oil fume in the oil fume purifier;

[0025] A purification cylinder 6 driven by a servo motor 5 is rotatably connected to the inner wall of the shell 1 and corresponds to the position between the two filter plates 4. A group of positive plate groups and a group of negative plate groups are arranged at intervals between the inner surfaces of the purification cylinder 6. The positive plate group and the negative plate group each include two purification plates 7 symmetrically arranged and fixedly connected to the purification cylinder 6. An oil removal chamber 10 is arranged between the two purification plates 7. An oil removal assembly that can reciprocally scrape oil from the purification plates 7 is installed on the oil removal chamber 10. A toothed ring 8 that cooperates with the oil removal assembly is installed on one side of the shell 1. A power supply module that supplies power to the positive plate group and the negative plate group respectively is installed on the other side of the shell 1. An oil drain valve 9 is connected to the bottom surface of the shell 1 and corresponds to the position directly below the purification cylinder 6.

[0026] The oil removal assembly includes a cleaning shaft 11 corresponding to the position of the oil removal chamber 10 and rotatably connected to the inner surface of the cleaning cylinder 6. The cleaning shaft 11 is symmetrically provided with a positive thread area and a negative thread area. A torsion spring 12 is fixedly provided at the rotation connection between the cleaning shaft 11 and the cleaning cylinder 6. A driven gear 13 that cooperates with the missing tooth ring 8 is fixedly installed at one end of the cleaning shaft 11.

[0027] A toothed surface is fixedly provided on the surface of the toothed ring 8 and corresponds to the position below the rotation axis of the purification cylinder 6. The full arc of the toothed surface is 120°, and the teeth are evenly distributed on the toothed surface.

[0028] The peripheral side surfaces of the positive thread area and the negative thread area are both drivingly connected with a scraper 14 that is slidably fitted with the oil removal chamber 10 and the purification electrode plate 7.

[0029] When the cleaning shaft 11 moves to the position of the toothed surface on the toothed ring 8, the cleaning shaft 11 is driven to rotate. After the cleaning shaft 11 rotates, the two scrapers 14 are driven to approach each other and finally maintain a close fit state.

[0030] When the cleaning shaft 11 moves to the non-tooth-missing surface position on the tooth-missing ring 8, the cleaning shaft 11 automatically resets to the initial angle under the action of the torsion spring 12. After the cleaning shaft 11 resets, the two scrapers 14 are driven to move away fully. During the process of the two scrapers 14 moving away fully, the oil stains on the purification plate 7 are scraped off again.

[0031] As the cleaning cylinder 6 rotates, the two scrapers 14 repeatedly move closer to or farther from each other, and then perform oil removal on the surface of the cleaning plate 7;

[0032] The oil removal assembly further includes a corrugated shield 15 disposed between the two scrapers 14 , and both side surfaces of the corrugated shield 15 are slidably fitted with the oil removal chamber 10 .

[0033] By setting the corrugated shield 15, the probability of external oil entering the oil removal chamber 10 is effectively reduced;

[0034] The power supply module includes an electric control box 16 fixed to the side of the shell 1, a positive ring rail 17 and a negative ring rail 18, a positive guide wheel 19 electrically connected to the positive plate group, and a negative guide wheel 20 electrically connected to the negative plate group. The positive guide wheel 19 is rotationally fitted with the positive ring rail 17, and the negative guide wheel 20 is rotationally fitted with the negative ring rail 18. The positive ring rail 17 is supplied with positive electricity through the electric control box 16, and the negative ring rail 18 is supplied with negative electricity through the electric control box 16.

[0035] The working principle and use process of the utility model are as follows: during operation, positive electricity is supplied to the positive plate group, and negative electricity is supplied to the negative plate group, so that the positive plate group and the negative plate group generate a purification electric field. When the range hood is working, the purification cylinder 6 rotates clockwise at a set speed. When the cleaning shaft 11 moves to the position of the toothed surface on the toothed ring 8, the cleaning shaft 11 rotates drivenly. After the cleaning shaft 11 rotates, the two scrapers 14 are driven to approach each other and finally remain in a fitting state. When the cleaning shaft 11 moves to the position of the non-toothed surface on the toothed ring 8, the cleaning shaft 11 is automatically reset to the initial angle under the action of the torsion spring 12. After the cleaning shaft 11 is reset, the two scrapers 14 are driven to move away fully. During the process of the two scrapers 14 moving away fully, the oil on the purification plate 7 is scraped again. As the purification cylinder 6 rotates, the two scrapers 14 repeatedly approach or move away from each other, and then the oil removal operation on the surface of the purification plate 7 is performed, and the cleaned oil can be discharged through the oil drain valve 9.
