[0037] Working principle: On sunny days, the refracting plate 3 irradiates the concentrated sunlight on the surface of the heat collecting pipe 5. The heat collecting pipe 5 converts solar energy into heat energy to heat the water inside the water pipe 6. After the water inside the water pipe 6 is heated, it flows into the hot water tank 7 for storage. The hot air of the hot water enters the exhaust pipe 8. The exhaust valve 11 is opened, and the hot air flows through the guiding pipe 24 to the nozzle 25 and then sprays out from the nozzle 25 to heat the heat storage bag 12. When the refracting plate 3 concentrates sunlight, it absorbs heat to heat the heat storage bag 12 on the outside. The hot water inside the heat storage bag 12 also flows into the hot water tank 7 through the telescopic pipe 13, then through the exhaust pipe 8 and the guiding pipe 24 to the nozzle 25 and sprays out to heat the heat storage bag 12. When it is necessary to replace and clean the heat storage bag 12, the pull column 21 is pulled. The pull column 21 drives the plug pin 18 to slide out of the T-shaped block 16. At the same time, it drives the sliding block 19 to slide inside the outer shell 17. The sliding block 19 compresses the spring 20, and the spring 20 generates elastic force. When the plug pin 18 slides out of the T-shaped block 16, the T-shaped block 16 can be taken out, and then the heat storage bag 12 can be taken out for replacement and cleaning. During installation, the pull column 21 is also pulled, and then the connecting block one 14 and the connecting block two 15 are aligned and inserted into the T-shaped block 16. Then the pull column 21 is released, and the spring 20 pushes the sliding block 19. The sliding block 19 drives the plug pin 18 to insert into the T-shaped block 16.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
