Description

Technical Field

[0001] This utility model relates to the field of solar water heater structure technology, and in particular to a portable solar water heater. Background Technology

[0002] A solar water heater is a device that uses solar energy to heat water. A portable solar water heater is a type of solar water heating equipment that is mobile, easy to install and use. It can be flexibly moved as needed and is suitable for different locations, such as outdoor activity areas, temporary residences, and construction sites. Utilizing solar energy as its energy source eliminates the consumption of traditional fossil fuels, reducing environmental pollution and lowering operating costs. Compared to some gas or electric water heaters, it eliminates safety hazards such as gas leaks or electric shocks. Portable solar water heaters include both portable and vehicle-mounted types.

[0003] Portable solar water heaters include outdoor solar hot water bags. The outer layer or inner liner of the hot water bag is made of black or dark-colored material, or coated with a black heat-absorbing coating. In existing technology, outdoor solar hot water bags are used by unscrewing the stopper, filling them with water to be heated, plugging them back in, and placing them in sunlight to absorb solar radiation for heating. However, this method of use has several problems: First, the shape and structure of the solar hot water bag are relatively fixed, resulting in slightly poor portability; second, the solar hot water bag is usually just a simple bag-like structure, and the heating area mainly depends on the surface area of ​​the bag itself, thus limiting the heating area; third, outdoor solar hot water bags generally have only one opening, making the water intake method relatively simple; fourth, outdoor solar hot water bags usually focus on solar heating function, and may not have specifically designed and optimized for heat preservation, resulting in poor heat preservation; and fifth, outdoor solar hot water bags are easily punctured by sharp objects.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-6 As shown, a portable solar water heater includes a hot water tank 1. A lid 2 is movably installed inside the upper part of the hot water tank 1. A heat-absorbing frame 3 is fixedly installed inside the hot water tank 1 near the upper part. There are three heat-absorbing frames 3, which are evenly distributed inside the hot water tank 1 near the upper part. The hot water tank 1 can be extended and folded, making the solar water heater easy to carry and store, and more robust and durable. The hot water tank 1 and the lid 2 have a heat insulation effect. The lid 2 can be rotated open to directly draw water from the inside of the hot water tank 1, or a water suction pipe can be inserted into the hot water tank 1 through the lid 2. The water drawing and filling methods are flexible enough. The hot water tank 1 and the heat-absorbing frame 3 can absorb solar radiation energy, and make the area of ​​the solar water heater heating water larger. The side of the heat-absorbing frame 3 that absorbs solar radiation energy can be adjusted and can be disassembled without affecting the folding of the hot water tank 1.

[0023] In this embodiment, the hot water tank 1 includes a hollow base 101, a heat-absorbing coating telescopic cylinder 102, a transparent heat-insulating telescopic cover 103, an internally threaded ring 104, a horizontal handle 105, an internally threaded sleeve 106, a No. 1 threaded plug 107, and a sealing gasket 108.

[0024] In this embodiment, the heat-absorbing coating telescopic cylinder 102 is fixedly installed on the upper surface of the hollow base 101 near the center. The transparent heat-insulating telescopic cover 103 is fixedly installed on the upper surface of the hollow base 101 at the edge. The internally threaded ring 104 is fixedly installed on the upper end of the heat-absorbing coating telescopic cylinder 102. The transverse handle 105 is fixedly installed on the outside of the internally threaded ring 104. The internally threaded sleeve 106 is fixedly installed on the upper end of the transparent heat-insulating telescopic cover 103 corresponding to the through hole. The first threaded plug 107 is screwed into the inside of the internally threaded sleeve 106. The sealing gasket 108 is sleeved on the outside of the first threaded plug 107. The upper end of the heat-absorbing coating telescopic cylinder 102 and the internally threaded sleeve 106 are connected. The lower surface of the threaded ring 104 is fixedly connected. When telescopic folding is required, open the bucket lid 2, unscrew the No. 1 threaded plug 107 inside the inner threaded sleeve 106, and press down the hot water bucket 1. The air between the heat-absorbing coating telescopic cylinder 102 and the transparent heat-insulating telescopic cover 103 is discharged from the inner threaded sleeve 106. Then, insert the No. 1 threaded plug 107 into the inner threaded sleeve 106. The heat-absorbing coating telescopic cylinder 102 can absorb solar radiation energy and convert it into heat energy. The transparent heat-insulating telescopic cover 103 allows sunlight to shine through onto the heat-absorbing coating telescopic cylinder 102 while reducing heat loss. The hollow base 101 also has a heat insulation function, and the sealing gasket 108 plays a sealing role.

[0025] In this embodiment, the bucket lid 2 includes a hollow threaded lid 201, a second threaded plug 202, a vertical handle 203, a sealing ring 204, and a sealing gasket 205.

[0026] In this embodiment, the hollow threaded cap 201 is screwed into the inside of the internal threaded ring 104, the second threaded plug 202 is screwed into the threaded through hole of the hollow threaded cap 201, the vertical handle 203 is fixedly installed on the upper surface of the hollow threaded cap 201, the sealing ring 204 is sleeved on the outside of the second threaded plug 202, and the sealing gasket 205 is sleeved on the outside of the hollow threaded cap 201. When it is necessary to open the bucket lid 2 to fill water, hold the horizontal handle 105 and the vertical handle 203, rotate the vertical handle 203 to allow the vertical handle 203 to exit the inside of the internal threaded ring 104, and pour the water to be heated into the heat-absorbing coating telescopic cylinder 102. When it is necessary to close the bucket lid 2, simply screw the hollow threaded cap 201 back into the inside of the internal threaded ring 104. The hollow threaded cap 201 has a heat insulation function.

[0027] In this embodiment, the heat absorption frame 3 includes a C-shaped clamping frame 301, a heat absorption plate 302, and a C-shaped clamping piece 303.

[0028] In this embodiment, three C-shaped clamping frames 301 are provided. The C-shaped clamping frames 301 are fixedly installed inside the hot water tank 1 near the upper end. C-shaped clamping pieces 303 are engaged in the slots at both ends of the heat-absorbing plate 302. The three C-shaped clamping frames 301 are evenly distributed inside the hot water tank 1 near the upper end. The semi-circular protrusion at the rear end of the C-shaped clamping piece 303 engages in the hemispherical groove of the C-shaped clamping frame 301. During the solar water heating process, when the tank lid 2 is opened, the C-shaped clamping piece 303 can rotate within the hemispherical groove of the C-shaped clamping frame 301 to adjust the heat-absorbing plate. The tilt angle of 302 allows the heat-absorbing plate 302 to absorb solar energy and transfer heat to the surrounding water. This, combined with the heat-absorbing coating telescopic cylinder 102, quickly heats the water. After the water is heated, the C-shaped clip 303 in the hemispherical groove of the C-shaped clip frame 301 is removed, the heat-absorbing plate 302 is taken off, and the bucket lid 2 is rotated on. When using water, the bucket lid 2 can be opened directly for use, or the second threaded plug 202 in the threaded through hole of the hollow threaded cover 201 can be unscrewed. The water suction pipe passes through the threaded through hole of the hollow threaded cover 201 and is inserted into the interior of the hot water bucket 1. The sealing ring 204 and the sealing gasket 205 play a sealing role.

[0029] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
