Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figure 1-8 As shown, this embodiment provides a solar-heated water cup, including: a cup body 1, a transparent cup lid 2 installed at the mouth of the cup body 1, and a solar heating component for heating the water in the cup body 1 inside the transparent cup lid 2.

[0032] The solar heating component includes an annular ring 3, a Y-shaped bracket 302, a first reflective part 303, an annular transparent shell 304, several second reflective parts 306, and a heat-conducting part. The annular ring 3 is fixedly installed on the inner wall of the transparent cup lid 2. The Y-shaped bracket 302 is fixedly installed on the upper part of the annular ring 3. The first reflective part 303 is fixedly installed at the upper center of the Y-shaped bracket 302. The annular transparent shell 304 is fixedly installed on the upper part of the Y-shaped bracket 302, and is located on the outer periphery of the first reflective part 303. The annular transparent shell 304 contains an encapsulated part. A black waxed paper ring and several second reflective parts 306 are fixedly installed inside the transparent cup lid 2, and the several second reflective parts 306 are all located above the first reflective part 303. The several second reflective parts 306 are arranged in a ring at equal angles around the first reflective part 303, and the several second reflective parts 306 can reflect the sunlight reflected by the first reflective part 303 to the surface of the black waxed paper ring inside the annular transparent shell 304. The heat-conducting part is in contact with the bottom of the annular transparent shell 304, and can conduct the heat generated by the black waxed paper ring irradiating sunlight to the water in the cup body 1.

[0033] The solar-heated water cup using the above technical solution mainly consists of a cup body 1, a transparent cup lid 2, and a solar heating component for heating the water inside the cup body 1. The solar heating component mainly consists of an annular ring 3, a Y-shaped bracket 302, a first reflector 303, an annular transparent shell 304, a black waxed paper ring, several second reflectors 306, and a heat-conducting component. In use, the several second reflectors 306 reflect the sunlight reflected by the first reflector 303 onto the surface of the black waxed paper ring inside the annular transparent shell 304, causing the black waxed paper ring to heat up rapidly and heat the annular transparent shell 304. Then, the heat generated by the sunlight irradiating the black waxed paper ring is directly conducted to the inside of the cup body 1 through the heat-conducting component to heat the water. The energy loss in the conversion process is small, thereby improving the heating efficiency of the water.

[0034] Specifically, in this embodiment, the first reflective part 303 is a convex lens, and the plurality of second reflective parts 306 are all plane mirrors. The convex lens and the plane mirror are configured to work together to reflect sunlight onto the plane mirror, and the plane mirror then reflects the sunlight reflected by the convex lens onto the surface of the black waxed paper ring inside the annular transparent shell 304, which allows more sunlight to enter the surface of the black waxed paper ring, thereby improving the heating efficiency.

[0035] Specifically, in this embodiment, in order to ensure that sunlight can penetrate the transparent cup lid 2 and the annular transparent shell 304, both the transparent cup lid 2 and the annular transparent shell 304 are made of transparent tempered glass. In order to ensure the heat conduction effect, the heat conduction part includes a circular aluminum alloy heat conduction plate 308 and an aluminum alloy heat conduction rod 309. In order to prevent water inside the cup body 1 from entering the interior of the transparent cup lid 2 and wetting the annular transparent shell 304, the first reflective part 303 and the second reflective part 306, thereby reducing the reflection intensity of sunlight, the circular aluminum alloy heat conduction plate 308 is sealed and fixedly installed on the inner side of the annular ring 3. In order to conduct heat, the circular aluminum alloy heat conduction plate 308 and the annular transparent shell 304 are connected by a number of aluminum alloy heat conduction blocks 305. The aluminum alloy heat conduction rod 309 is fixedly installed at the bottom of the circular aluminum alloy heat conduction plate 308. When the transparent cup lid 2 is placed on the mouth of the cup body 1, the bottom end of the aluminum alloy heat conduction rod 309 extends into the interior of the cup body 1 to facilitate heating the water inside the cup body 1.

[0036] Specifically, in this embodiment, in order to further improve the heat conduction effect, the heat conduction part also includes an aluminum alloy heat conduction column 310. The aluminum alloy heat conduction column 310 is vertically and fixedly installed on the upper part of the inner bottom wall of the cup body 1. When the bottom end of the aluminum alloy heat conduction rod 309 extends into the interior of the cup body 1, its bottom end contacts the upper end of the aluminum alloy heat conduction column 310. The aluminum alloy heat conduction column 310 can accelerate the heat conduction to the water inside the cup body 1, thereby improving the efficiency of heating water.

[0037] Specifically, in this embodiment, in order to better combine the aluminum alloy heat-conducting rod 309 and the aluminum alloy heat-conducting column 310, there is an insertion hole 312 at the bottom end of the aluminum alloy heat-conducting rod 309. When the bottom end of the aluminum alloy heat-conducting rod 309 extends into the interior of the cup body 1, the upper end of the aluminum alloy heat-conducting column 310 is inserted into the insertion hole 312.

[0038] Specifically, in this embodiment, in order to improve the stability of the connection between the bottom end of the aluminum alloy heat-conducting column 310 and the inner bottom wall of the cup body 1, a reinforcing seat 311 is fixedly installed at the connection between the bottom end of the aluminum alloy heat-conducting column 310 and the inner bottom wall of the cup body 1.

[0039] Specifically, in order to facilitate the assembly of the cup body 1 and the transparent cup lid 2, in this embodiment, an external thread 105 is provided on the outside of the cup mouth of the cup body 1, and an internal thread 202 matching the external thread 105 is provided inside the transparent cup lid 2. The transparent cup lid 2 is then threaded onto the cup mouth of the cup body 1 by the mutual engagement of the internal thread 202 and the external thread 105.

[0040] Specifically, in order to improve the sealing between the transparent cup lid 2 and the cup mouth of the cup body 1 to prevent water leakage, in this embodiment, a silicone sealing ring 307 is snapped into the bottom of the annular ring 3. When the transparent cup lid 2 is tightened, the bottom of the silicone sealing ring 307 abuts against the edge of the cup mouth of the cup body 1.

[0041] Specifically, in order to prevent excessive air pressure when the internal temperature of the transparent cup lid 2 rises, in this embodiment, an air hole 201 is reserved on the top wall of the transparent cup lid 2. When the internal temperature of the transparent cup lid 2 rises and the air pressure becomes too high, the pressure can be released through the air hole 201. In order to prevent foreign objects from easily entering the air hole 201, the diameter of the air hole 201 is not greater than 0.5mm.

[0042] Specifically, in order to protect the bottom of the cup body 1, in this embodiment, an annular mounting groove 101 is provided on the edge of the bottom of the cup body 1. A T-shaped retaining ring 103 is integrally formed in the annular mounting groove 101, and a rubber protective ring 102 is installed in the annular mounting groove 101. An annular groove 104 is provided in the rubber protective ring 102. The retaining ring 103 is inserted into the annular groove 104. The rubber protective ring 102 is used to protect the bottom of the cup body 1 and prevent the bottom of the cup body 1 from being bumped. The retaining ring 103 and the annular groove 104 cooperate with each other to make it easy to install and remove the rubber protective ring 102.

[0043] Specifically, in this embodiment, a thermometer is embedded in the side wall of the cup body 1 to display the water temperature.

[0044] Specifically, in this embodiment, a photothermal material is used instead of the black waxed paper ring that reflects sunlight into the annular transparent shell 304. The interior of the annular transparent shell 304 is filled with the photothermal material, which includes, but is not limited to, carbon-based nanomaterials, metal-based nanomaterials, and inorganic semiconductor polymers.

[0045] Carbon-based nanomaterials mainly include graphene, graphene oxide (GO), reduced graphene oxide (rGO), and carbon nanotubes. Due to their wide visible light absorption range and strong light absorption characteristics, when exposed to a light source, electrons in carbon-based materials can absorb the energy of photons, thus exciting them. Excited electrons are unstable, and during their decay back to the ground state, a photothermal effect occurs, causing a local temperature increase. Studies have shown that compared to traditional carbon black or graphite, nanoscale carbon nanotubes and graphene have lower interfacial reflectivity and significantly improved light absorption performance.

[0046] Metallic nanomaterials can absorb photons and convert them into thermal energy through the localized surface plasmon resonance (LSPR) effect. When electrons on the surface of a metallic nanomaterial absorb photon energy, hot electrons are generated. Through a scattering process between electrons, these hot electrons rapidly redistribute their energy among a large number of low-energy electrons, establishing an electron temperature. Energy is then transferred to the lattice through electron-phonon interactions, leading to lattice thermalization. Finally, energy is transferred from the lattice to the external environment through phonon interactions. Since the LSPR effect is related to the size and structure of the plasmon nanomaterial, its absorption of near-infrared light can be enhanced by altering its size or structure. Au nanoparticles and Ag nanoparticles are considered the most promising photothermal conversion metallic materials due to their strong light absorption and photothermal conversion properties.

[0047] Traditional semiconductor materials have wide band gaps, requiring the absorption of high-energy incident light, such as ultraviolet light, to excite electrons and release heat during their return to the ground state. With ongoing research into semiconductor materials, black semiconductor materials with narrow band gaps are being discovered, such as black titanium dioxide (TiO2) and titanium trioxide (TiO3). These materials can excite electrons and release heat simply by absorbing visible light, greatly expanding the applications of semiconductor materials in photothermal conversion.

[0048] In summary, the solar-heated water cup provided by this invention mainly consists of a cup body 1, a transparent lid 2, and a solar heating component for heating the water inside the cup body 1. The solar heating component mainly comprises an annular ring 3, a Y-shaped bracket 302, a first reflective part 303, an annular transparent shell 304, a black waxed paper ring, several second reflective parts 306, and a heat-conducting part. In use, the transparent lid 2 is unscrewed, water is added to the cup body 1, the transparent lid 2 is then tightened, and the solar-heated water cup is placed in sunlight. Sunlight shines through the transparent lid 2 onto the first reflective part 303. The light is emitted from the surface of the black waxed paper ring inside the annular transparent shell 304 to the bottom of the second reflective part 306, and then reflected to the surface of the black waxed paper ring inside the annular transparent shell 304. This causes the black waxed paper ring to heat up rapidly, heating the annular transparent shell 304. The heat is then transferred to the circular aluminum alloy heat-conducting plate 308 through several aluminum alloy heat-conducting blocks 305, and then conducted to the aluminum alloy heat-conducting rod 309 and aluminum alloy heat-conducting column 310 to heat the water inside the cup body 1. The heat generated by the black waxed paper ring irradiating sunlight is directly conducted to the inside of the cup body 1 to heat the water. The energy loss in the conversion process is small, thereby improving the heating efficiency of the water.
