DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, the present utility model provides a technical solution: an electric heater with a detachable filter screen, which includes an electric heater housing 1. An installation groove 3 is provided on the front surface of the electric heater housing 1. A filter screen 2 is arranged inside the installation groove 3. An installation component is arranged between the filter screen 2 and the installation groove 3. The installation component includes side grooves 4 opened on the surfaces of both ends inside the installation groove 3. A fixing block 5 is arranged inside the side groove 4. A rope groove 6 is opened on the surface of one end inside the fixing block 5. A pull rope 7 is arranged inside the rope groove 6. A first spring 8 is also arranged between the fixing block 5 and the side groove 4. Fixing grooves 18 adapted to the fixing blocks 5 are opened on both sides of the filter screen 2. A groove 9 is opened on the bottom surface of the front side of the electric heater housing 1. The groove 9 is communicated with the rope groove 6. A rotating disk 10 is rotatably connected inside the groove 9. A placement groove 11 is also opened on the inner surface of the installation groove 3. A telescopic column 12 is arranged inside the placement groove 11. A pressing block 13 is arranged at the front end of the telescopic column 12. A second spring 14 is sleeved on the surface of the telescopic column 12. The rear end of the second spring 14 is fixedly connected with the inner surface of the placement groove 11. The front end of the second spring 14 is fixedly connected with the rear surface of the pressing block 13. Finger holes are opened on the front surface of the rotating disk 10, which is convenient for personnel to rotate the rotating disk 10. The diameter of the pressing block 13 is 0.9 times the diameter of the placement groove 11, so that when the pressing block 13 is stressed, it can be completely inside the placement groove 11; when installing the filter screen 2, personnel first rotate the rotating disk 10. When the rotating disk 10 rotates, it drives the pull rope 7 to move along the inside of the rope groove 6. When the pull rope 7 moves, it drives the fixing block 5 to move, so that the fixing block 5 is finally completely inside the side groove 4. At this time, the first spring 8 is stressed and contracts. Then personnel place the filter screen 2 inside the installation groove 3. At this time, the pressing block 13 is stressed and pushes the telescopic column 12 to contract. At the same time, the second spring 14 is stressed and contracts. When the filter screen 2 is completely inside the installation groove 3, personnel release the rotating disk 10. At this time, the first spring 8 is not stressed and expands, pushing the fixing block 5 back to its original position, so that one side of the fixing block 5 is engaged inside the fixing groove 18, completing the installation and fixation of the filter screen 2; the installation of the filter screen 2 of the existing electric heater is relatively cumbersome. Personnel need to use auxiliary tools to install and disassemble it, which is not convenient for cleaning and maintaining the filter screen 2 of the electric heater in the later stage; by designing the electric heater housing 1, the filter screen 2, the installation groove 3, and the installation component, personnel can quickly install the filter screen 2 on the electric heater housing 1 without using tools, improving the installation and later disassembly efficiency, facilitating users to disassemble the filter screen 2 for cleaning and maintenance in the later stage, and the overall structure is simple and practical.

[0019] In this embodiment, preferably, please refer to Figure 1As shown, it further includes a protection component. The protection component includes a protection cover 15 on the front side of the electric heater housing 1. A connecting rod 16 is fixedly connected to the front side of the protection cover 15. A rotating rod 17 is fixedly connected to the end of the connecting rod 16 away from the protection cover 15. The rotating rod 17 is rotatably connected to the surface of the electric heater housing 1. The protection cover 15 is made of plastic, effectively reducing the investment in manufacturing costs, being economical and practical. By designing the protection component, after the filter screen 2 is installed, the user can rotate the protection cover 15. The protection cover 15 rotates around the rotating rod 17 under the action of the connecting rod 16, so that the protection cover 15 finally covers the groove 9, thereby ensuring that the rotating disk 10 will not be exposed to the outside, effectively avoiding the rotating disk 10 being accidentally touched, and making the filter screen 2 more stable after installation.
