[0025] As a further implementation of this solution, the lower outer liner 1 and the upper outer liner 2 have the same shape, and the inner sides of the lower outer liner 1 and the upper outer liner 2 are both provided with a water tank 4, and the lower outer liner 1 and the upper outer liner 2 are both fixed with an ear seat on one side, and the upper end of the silicone rubber ring 3 is fitted with the bottom end of the upper outer liner 2, so as to achieve a sealing effect between the lower outer liner 1 and the upper outer liner 2;

[0026] As a further implementation of this solution, the inner tank component 5 is installed inside the water tank 4, and the pressure reducing heating component 6 is inside the water tank 4. The number of the pressure reducing heating components 6 can increase the contact area between the pressure reducing heating components 6 and the water;

[0027] As a further implementation of this solution, the metal shell 51 is composed of multiple hollow cylinders, and the number of side plates 54 is two. The side plates 54 are installed at the front and rear ends of the metal shell 51 to facilitate the installation of the centering support rod 55, so that the temperature memory metal 56 is inside the liquid groove 52;

[0028] As a further implementation of the present invention, a load-bearing column 57 is fixedly connected to one side of the rear end side plate 54. There are two load-bearing columns 57. The inner side of the load-bearing column 57 is hollow. The load-bearing column 57 is sleeved on the outer side of the middle support rod 55. There are several temperature memory metals 56. The temperature memory metals 56 are installed inside the liquid groove 52. When the temperature memory metals 56 are stimulated by temperature, they collide with the supersaturated sodium acetate solution inside the liquid groove 52.

[0029] As a further implementation of the present solution, the copper disk 61 is in the shape of a hollow cylinder, the front end and the rear end of the copper disk 61 are fixedly connected to the metal housing 51, and the copper disk 61 is installed inside the mounting opening 53. The number of the copper disks 61 corresponds to the number of the mounting openings 53, and it serves to balance the pressure inside the liquid groove 52 when the temperature inside the liquid groove 52 increases.

[0030] As a further implementation scheme of the present scheme, the pressure reducing port 65 is connected to the column slide hole 62, the pressure reducing port 65 is connected to the water tank 4, there are several column slide holes 62, the column slide hole 62 is in the shape of a cylinder, the column slide plate 63 is in the shape of a cylinder, the outer side of the silicone rubber ring 64 is fitted with the inner side of the column slide hole 62, and one side of the limit baffle 66 is fitted with one side of the column slide plate 63, thereby improving the heating efficiency of the water inside the lower outer liner 1 and the upper outer liner 2.

[0031] Working process: during the use of the device, the inner tank component 5 and the pressure reducing heating component 6 are installed inside the lower outer tank 1, and the upper outer tank 2 is fixed by bolts. The silicone rubber ring 3 has the effect of sealing between the lower outer tank 1 and the upper outer tank 2. The lower outer tank 1 and the upper outer tank 2 are filled with water, and the liquid groove 52 is filled with a supersaturated sodium acetate solution. When in use, the water inside the upper outer tank 2 is heated by the existing collector. After the heated water is continuously used, the water temperature inside the upper outer tank 2 is gradually reduced after the water is replaced. The water temperature absorbs the heat of the metal shell 51, thereby reducing the temperature inside the liquid groove 52. At this time, the temperature memory metal 56 will jump. The temperature memory metal 56 will jump when it exceeds or is lower than thirty-five degrees. When the temperature memory metal 56 jumps, it stimulates the supersaturated sodium acetate solution to crystallize and release heat. The supersaturated sodium acetate solution is in a stable state without heat. When there is a stimulation such as knocking on the temperature memory metal 56, it will become a solid stable state. A large amount of heat will be released in this process. At this time, the liquid The heat inside the body groove 52 is high, and the hot air inside the liquid groove 52 expands. The gas pushes the column slide 63 to expand outward, and the column slide 63 pushes the reset spring 67 to deform. The elastic force of the reset spring 67 is small, and the reset spring 67 can reset the column slide 63. At the same time, the movement of the column slide 63 can reduce the pressure inside the liquid groove 52 and increase the service life of the liquid groove 52. The silicone rubber ring 64 has the effect of sealing between the column slide 63 and the copper plate 61. The water inside the column slide hole 62 flows into the water tank 4 from the pressure reducing port 65. At this time, the hot air is filled in the column slide hole 62, and the external water can be heat-conducted through the copper plate 61, thereby improving the heating efficiency of the water inside the lower outer tank 1 and the upper outer tank 2. The limit baffle 66 has the effect of limiting the movement of the column slide 63 to prevent the column slide 63 from escaping from the column slide hole 62. At the same time, the water inside the lower outer tank 1 and the upper outer tank 2 is heated by the collector. When the overall temperature of the water tank is higher than fifty degrees, the sodium acetate supersaturated solution returns to a liquid state.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
