[0018] Example: Reference Figure 1-2An oil-filled electric heater includes an oil-filled heater body, which includes a heat dissipation structure 1. The surface of the heat dissipation structure 1 is provided with several heat dissipation fins 2. A housing 3 is installed on the outside of the heat dissipation structure 1, and multiple heat dissipation grooves 4 are formed on the housing 3. Heat from the heat dissipation fins 2 is dissipated through the heat dissipation grooves 4. Two first through grooves 5 are formed on both sides of the housing 3. Cleaning components are installed on the housing 3 on both sides of the heat dissipation structure 1. The cleaning components include a movable component and a cleaning component 12. The cleaning component 12 includes a fixed base and a brush strip. The brush strip is installed on the fixed base and is made of a high-temperature resistant material, used for periodically cleaning the heat dissipation fins 2. The movable component passes through the first through grooves 5 and is fixedly connected to the cleaning component 12. The movable component includes a horizontal column 6 and two movable columns 7. The horizontal column 6 is connected to the movable columns 7, and the movable columns 7 pass through the first through grooves 5 and are connected to the cleaning component 12. A limiting groove 8 is formed on the housing 3, and the limiting groove 8 communicates with the upper end of the first through groove 5. A movable groove 9 is provided on the horizontal column 6, and a movable column 7 passes through the movable groove 9 and the first through groove 5 to connect with the cleaning component 12. After cleaning is completed, the horizontal column 6, the movable column 7, and the cleaning component 12 are moved to the position of the limiting groove 8. At the same time, the movable column 7 moves on the movable groove 9, so that the movable column 7 is locked in the limiting groove 8, thus fixing the cleaning component 12. A second through groove 10 is provided on both sides of the housing 3. A fixed column 11 is connected to the horizontal column 6. The fixed column 11 passes through the second through groove 10 and is fixedly connected to the cleaning component 12. When the movable component moves up and down, the fixed column 11 can move stably and directly without tilting.

[0019] The working principle of this embodiment is as follows: The heat on the heat dissipation fins 2 is dissipated from the heat dissipation grooves 4, and the heat dissipation fins 2 are cleaned periodically. This is achieved by pushing the horizontal column 6, the moving column 7, and the cleaning component 12 up and down in the first through groove 5, while the fixed column 11 moves up and down in the second through groove 10, thereby driving the cleaning component 12 to move up and down. This cleans the heat dissipation fins 2 on the heat dissipation structure 1, preventing dust from accumulating on their surface and affecting their heat transfer efficiency. After cleaning is completed, the horizontal column 6, the moving column 7, and the cleaning component 12 are moved to the position of the limiting groove 8, while the moving column 7 moves on the movable groove 9, thereby locking the moving column 7 in the limiting groove 8, thus fixing the cleaning component 12.
