[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an energy-saving regenerative gas electric heater that utilizes waste heat recovery, comprising a base 1, a heating box 2 fixedly connected to the upper surface of the base 1, an outlet ring 3 fixedly connected to the outer wall of the heating box 2, a limiting block 4 fixedly connected to the outer wall of the outlet ring 3, a sealing cover 5 slidably connected to the outer wall of the limiting block 4, a spring 6 inside the sealing cover 5, a sealing sheet 7 fixedly connected to the outer wall of the spring 6, a slidably connected outer wall of the sealing sheet 7 inside the sealing cover 5, a locking post 8 slidably connected to the inside of the sealing cover 5, a connecting piece 9 fixedly connected to the outer wall of the locking post 8, a slidably connected outer wall of the connecting piece 9 inside the sealing cover 5, a second spring 10 on the outer wall of the locking post 8, one end of the second spring 10 fixedly connected to the inside of the sealing cover 5, and the other end of the second spring 10 fixedly connected to the outer wall of the connecting piece 9, and a heating assembly on the upper surface of the base 1.

[0026] Specifically, the base 1 fixes the heating chamber 2, which in turn fixes the outlet ring 3. The outlet ring 3 releases heat from the interior of the heating chamber 2 and fixes the limiting block 4. The limiting block 4 limits the sealing cover 5, which seals the heating chamber 2. The spring 6 inside the sealing cover 5 rebounds and can drive the sealing plate 7 to seal the outlet ring 3. The sliding of the outlet ring 3 inside the sealing cover 5 can drive the sealing plate 7 to slide. The sealing plate 7 limits the locking post 8. The sliding of the sealing plate 7 can drive the locking post 8 to slide inside the outlet ring 3. The locking post 8 can drive the connecting piece 9 to slide. The connecting piece 9 can drive the spring 10 to compress. The spring 10 rebounds and can drive the locking post 8 to engage the outlet ring 3. Pulling the locking post 8 can quickly remove the sealing cover 5, allowing for regular cleaning and maintenance of the interior of the heating chamber 2.

[0027] Reference Figure 1 The heating assembly includes a support frame 11, the lower surface of which is fixedly connected to the upper surface of the base 1, and the upper surface of the support frame 11 is fixedly connected to the electric heater body 12.

[0028] Specifically, the base 1 provides fixed support to the support frame 11, which in turn fixes the electric heater body 12, which is used to heat the air.

[0029] Reference Figure 1 and Figure 4An inlet pipe 13 is fixedly connected to the outer wall of the electric heater body 12. The outer wall of the inlet pipe 13 is fixedly connected to the inside of the heating box 2. A recovery box 14 is fixedly connected to the outer wall of the electric heater body 12. A regeneration gas pipe 15 is fixedly connected to the outer wall of the recovery box 14. The outer wall of the regeneration gas pipe 15 is fixedly connected to the inside of the heating box 2.

[0030] Specifically, the inlet pipe 13 is used to connect the electric heater body 12 and the heating box 2 to transfer heat. The electric heater body 12 serves to fix the recovery box 14. The recovery box 14 is used to collect the waste heat generated when the electric heater body 12 is working. The regeneration gas pipe 15 is used to connect the heating box 2 and the recovery box 14 to transfer the heat of the waste heat.

[0031] Reference Figure 5 and Figure 6 A filter plate 16 is slidably connected inside the recycling bin 14. A connecting frame 17 is fixedly connected to the outer wall of the filter plate 16. The outer wall of the connecting frame 17 is slidably connected inside the recycling bin 14. A sliding piece 18 is slidably connected inside the connecting frame 17. A first spring 19 is provided on the outer wall of the sliding piece 18. The outer wall of the first spring 19 is fixedly connected to the inside of the connecting frame 17. A sliding column 20 is fixedly connected to the outer wall of the connecting frame 17. The outer wall of the sliding column 20 is slidably connected to the inside of the recycling bin 14. A sliding column 21 is slidably connected inside the recycling bin 14. A lever 22 is fixedly connected to the outer wall of the sliding column 21. The outer wall of the lever 22 is slidably connected to the inside of the recycling bin 14. A second spring 23 is provided on the outer wall of the sliding column 21. One end of the second spring 23 is fixedly connected to the inside of the recycling bin 14, and the other end of the second spring 23 is fixedly connected to the outer wall of the lever 22.

[0032] Specifically, the filter plate 16 installed inside the recycling bin 14 filters the heat generated by the electric heater body 12 during operation. The filter plate 16 fixes the connecting frame 17. The filter plate 16 can be easily removed by manually pulling the connecting frame 17. The first spring 19 installed inside the connecting frame 17 can rebound the sliding plate 18. The sliding plate 18 drives the sliding column 20 to slide inside the recycling bin 14, which can lock the recycling bin 14, thereby fixing the connecting frame 17 and the filter plate 16 inside the recycling bin 14. When it is necessary to remove the filter plate 16 and the connecting frame 17 from the recycling bin 14, it can be done by pulling... The lever 22 drives the sliding column 21 to slide inside the recycling box 14, while simultaneously compressing the second spring 23. This, in turn, compresses the sliding column 20 by sliding the sliding column 21 inside the recycling box 14, forcing the sliding column 20 out of the recycling box 14. At this point, pulling the connecting frame 17 can slide the filter plate 16 out of the recycling box 14, completing the disassembly of the filter plate 16. This allows for timely cleaning of impurities adhering to the filter plate 16 and more effective transfer of residual heat energy. After the filter plate 16 is disassembled, pulling the lever 22 stops. The rebound action of the second spring 23 resets the sliding column 21, preventing any disruption to the reinstallation of the filter plate 16.

[0033] Working principle: When the electric heater is needed, the electric heater body 12 is activated to release heat, which is then used to heat the air inside the heating chamber 2 through the inlet pipe 13. When the electric heater body 12 is working, it releases heat, which passes through the filter plate 16 into the recovery box 14, and then enters the heating chamber 2 through the regeneration gas pipe 15. The residual heat is used to heat the heating chamber 2 again, achieving an energy-saving effect. At the same time, when the inside of the heating chamber 2 needs to be maintained, the sealing cover 5 can be removed to clean and maintain the inside of the heating chamber 2. By pulling the locking post 8, the connecting piece 9 slides inside the sealing cover 5, while the second spring 10 is compressed, which causes the locking post 8 to slide out of the outlet ring 3. At this time, the rebound of the first spring 6 causes the sealing piece 7 to slide inside the sealing cover 5, which limits the locking post 8, achieving the effect of quickly removing the sealing cover 5 so as to effectively clean and maintain the inside of the heating chamber 2.

[0034] When the filter plate 16 needs to be removed from the inside of the recycling box 14 for cleaning, the sliding column 21 is slid inside the recycling box 14 by manually pulling the lever 22, which in turn compresses the second spring 23. This causes the sliding column 21 to squeeze the sliding column 20, which then slides out of the recycling box 14. This causes the sliding plate 18 to slide inside the connecting frame 17, which in turn compresses the first spring 19. At this time, by pulling the connecting frame 17, the filter plate 16 is slid out of the recycling box 14, achieving the effect of quickly disassembling the filter plate 16 and cleaning it in a timely manner. This electric heater can not only effectively clean and maintain the heating box 2, but also quickly disassemble the filter plate 16, effectively cleaning impurities.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
