In addition, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] like Figures 1 to 4 As shown, the utility model provides a portable mobile solar water heater, comprising a base 1, a barrel-shaped shell 2 mounted on the base and capable of rotating backward relative to the base, a solar heater 3 arranged in the shell, a handle 4 mounted on the shell, and a top cover 5 arranged on the top of the solar heater; wherein the shell 2 comprises a circular base (not shown), a rear shell 201, a left door 202, and a right door 203, wherein the circular base is mounted on the base 1, the rear shell 201 is a semicircular structure, the rear shell 201 is fixed on the circular base, the left door 202 and the right door 203 are connected to each other. They are all arc-shaped structures. The left door 202 and the right door 203 are installed and fixed on both sides of the rear shell 201 by hinges 6, and combined with the rear shell 201 to form a barrel-shaped structure matching the circular base; the inner side walls of the rear shell 201, the left door 202, and the right door 203 are provided with a first curved glass mirror 7, a second curved glass mirror 8, and a third curved glass mirror 9 that imitate the rear shell, the left door, and the right door; the first curved glass mirror 7, the second curved glass mirror 8, and the third curved glass mirror 9 are combined to form a circular glass mirror, and a circle of light transmission area 10 is provided between the circular glass mirror and the solar heater 3.

[0026] Further, if Figure 3 , Figure 4As shown, in this embodiment, a bracket 11 is provided on the outer side wall of the rear shell 201, and the upper end of the bracket 11 is hinged to the rear shell 201. When the shell 2 is upright on the base 1, the bracket 11 is close to the outer side wall of the rear shell 201. When the shell 2 is rotated backward at a certain angle relative to the base 1, the bracket 11 is away from the rear shell 201 under the action of gravity, and the end is in contact with the ground to support the shell 2.

[0027] It should be noted that in the present embodiment, the bracket 11 can be installed on the rear shell through a connecting seat and a rotating shaft, and can also be installed on the rear shell through a soft connector. The present application does not impose any limitation on the specific installation form of the bracket. Those skilled in the art can adopt any connection method that can achieve the above functions, and the number of brackets 11 can be set to one or two as needed.

[0028] Furthermore, in this embodiment, the solar heater 3 is a barrel-shaped structure. The solar heater 3 can directly use the existing large-diameter solar heat absorbing tube. The bottom of the solar heater 3 is fixed on the circular base of the shell 2. The height of the solar heater is 750mm, the inner tube diameter is 136mm, the outer tube diameter is 160mm, the volume is 10.88 liters, and the heating area is 3768cm 2 The outer diameter of the shell is 300-320mm, preferably 310-320mm, and the thickness of the shell is controlled at 10-12mm to ensure the strength of the shell. The inner diameter of the shell (circular glass mirror) after the curved glass mirror is pasted is 286mm, that is, a 63mm wide light transmission area 10 is left between the circular glass mirror and the solar heater.

[0029] Furthermore, in the present embodiment, both ends of the carrying handle 4 are installed on both sides of the shell 2 and are arranged close to the top of the shell 2; the carrying handle 4 is mainly arranged to facilitate carrying the water heater. The present application does not make any limitation on the specific installation form of the carrying handle 4, and those skilled in the art can install the carrying handle 4 of the present application with reference to the installation method of the existing carrying handle or carrying handle.

[0030] Furthermore, in the present embodiment, the first curved glass mirror 7, the second curved glass mirror 8, and the third curved glass mirror 9 are all composed of curved glass and a silver layer plated on the bottom of the curved glass. The silver layers of the first curved glass mirror 7, the second curved glass mirror 8, and the third curved glass mirror 9 are fixed to the inner walls of the rear shell, the left door, and the right door by gluing. When sunlight hits the curved glass mirror, because the curved glass has a thickness (2-3 mm), part of the light is reflected and passes through the light transmission zone 10 to the solar heater 3, while the other part of the light is refracted into the glass and is totally reflected on the silver layer behind the glass. The totally reflected light is transmitted in the glass and is refracted again when it reaches the junction of the curved glass mirror and the air, and then passes through the light transmission zone 10 to the solar heater 3.

[0031] The water heater provided by the utility model changes the optical path of sunlight through reflection and refraction under the action of three curved glass mirrors and the light transmission zone, and irradiates the light to the part of the solar heater 3 that cannot directly absorb sunlight, so that the solar heater can be heated in all directions at 360 degrees while realizing a miniaturized structure.

[0032] Experiments have shown that the height of the solar heater is 750mm, the inner diameter is 136mm, the outer diameter is 160mm, the volume is 10.88 liters, and the heating area is 3768cm 2 ; The outer diameter of the shell is 310mm, the thickness of the shell is 10mm, and the inner diameter of the shell (circular glass mirror) after the curved glass mirror is pasted is 286mm, that is, a 63mm wide light transmission area 10 is left between the circular glass mirror and the solar heater 3. Taking the water heater as an example, the solar heater 3 is rotated backward 45°~50° so that the front of the solar heater 3 faces the sun, and the left door 202 and the right door 203 are opened outward 45°~50°. After about 3~3.5 hours of sunlight exposure, 10 liters of hot water (100℃) can be heated. It can be heated twice a day, accounting for 20 liters of hot water, which can save about 2 kWh of electricity.

[0033] The above data was collected from March 1 to March 15, 2024, at a geographical location of 44° north latitude. If it is in summer or in the south, the heating speed will be faster and the effect will be more significant.

[0034] The above description is only a specific implementation case of the utility model, but the technical features of the utility model are not limited thereto. Any changes and modifications made by any technician in the field within the field of the utility model are within the scope of the patent of the utility model.
