when the phase-change energy storage material 320 is heated to the highest temperature range, the thermal spring 540 is heated and stretched, the switching valve core 520 is pushed to the end far away from the heat conducting shaft 530, so that the communication relationship between the heat storage liquid inlet end 311 and the first circulating pipe 411 is gradually cut off, at this time, the second through hole 522 communicates the first heat preservation pipe 431 with the second heat preservation pipe 432, and the circulating medium sequentially flows through the first heat preservation pipe 431, the second through hole 522 and the second heat preservation pipe 432 from the first circulating pipe 411 and then enters the second circulating pipe 412 to circulate.
Example five
In this embodiment, referring to fig. 2 and 3, since the elongation process of the thermal spring 540 is slow, after the switching valve core 520 cuts off the communication between the first through hole 521 and the heat storage liquid inlet 311 and the first circulating pipe 411, the second through hole 522 may not be in communication with the first heat preservation pipe 431 and the second heat preservation pipe 432, which may result in the obstruction of the circulation of the medium, and thus the warmer cannot be used normally, the applicant performs the following modifications:
a supplementary liquid inlet pipe 421, a supplementary liquid outlet pipe 422 and a pressure valve 600 are added, a liquid inlet hole 621 of the pressure valve 600 is communicated with the first circulating pipe 411 through the supplementary liquid inlet pipe 421, and a liquid outlet hole 625 is communicated with the second circulating pipe 412 through the supplementary liquid outlet pipe 422;

In the initial state, the valve element 660 is tightly attached to the sealing taper hole 622 under the action of the spring 650, so that the communication between the liquid inlet hole 621 and the diversion channel 624 is cut off, and the pressure valve is closed.
When the switching valve core 520 cuts off the communication between the first through hole 521 and the heat storage liquid inlet 311 and the first circulation pipe 411, and the second through hole 522 may not be in communication with the first heat preservation pipe 431 and the second heat preservation pipe 432, the hydraulic pressure of the supplementary liquid inlet pipe 421 increases, so that the hydraulic pressure overcomes the spring force to push the valve core 660 open, the liquid inlet hole 621 is in communication with the diversion channel 624, and the medium enters the liquid outlet hole 625 through the diversion channel 624 and finally circulates through the supplementary liquid outlet pipe 422. In this process, the medium in the heat storage tube continues to heat the phase change energy storage material 320, so that the phase change energy storage material continues to heat the heat conduction shaft, that is, the thermal spring 540 continues to heat, that is, continues to elongate until the second through hole connects the first heat preservation tube 431 and the second heat preservation tube 432, the hydraulic pressure of the supplementary liquid inlet tube 421 decreases, the spring drives the valve core to reset, the pressure valve is closed, at this time, the medium enters the circulation through the first heat preservation tube 431 and the second heat preservation tube 432, and the phase change energy storage module 300 enters the energy storage completion and heat preservation state.
Example six
In this embodiment, referring to fig. 2 to 4, when the phase-change energy storage module 300 needs to be used for supplying heat, the temperature of the phase-change energy storage material 320 is reduced to a temperature at which the thermal spring is retracted, which causes the medium to be unable to enter the heat storage tube to absorb the heat of the phase-change energy storage material, so that the applicant performs the following improvements:

The electromagnet 340 is fixed on the fixing plate 330, and the fixing plate 330 is fixed outside the phase-change energy storage module 300.
When the phase-change energy storage module 300 is needed to supply heat, the electromagnet 340 is electrified, the electromagnet 340 drives the switching valve core 520 to overcome the elasticity of the thermal spring to move towards the heat conducting shaft through the switch rod 350 until the end face of the switching valve core 520 is tightly attached to the end face of the heat conducting shaft, at the moment, the first through hole is communicated with the heat storage liquid inlet end and the first circulating pipe 411, and the medium is connected into the heat storage pipe to absorb heat. The temperature of the phase-change energy storage material is reduced until the temperature of the thermal spring is reduced to the retraction temperature, and then the electromagnet is powered off, at the moment, the switching valve core cannot move, and the heat storage pipe keeps medium circulation. In the scheme, the phase-change energy storage can be selected from polyalcohols with the phase-change temperature of about 100 ℃, such as NPG.
