Technical Field

[0001] The utility model relates to the technical field of water purifiers, in particular to a solar water purifier. Background Art

[0002] As people's environmental awareness increases, clean energy such as solar energy has been widely used and applied to fields such as water purifiers. Patent 202320196773.6 discloses a solar water purifier, including a frame and a solar water pump, a water tank is fixedly installed on the top of the frame, an evaporation base is fixedly installed on the outer wall of the inclined end of the frame, the evaporation base adopts a polypropylene plate, a water collecting plate is fixedly installed on the outer wall of the evaporation base, a conduction component for water conduction is arranged between the water tank and the evaporation base, a matching plate is fixedly installed on the inner wall of the bottom of the water collecting plate, and a water collecting pipe is fixedly installed on the outer wall, and a circulation component for water circulation is arranged on the outer wall of the frame. Although this solar water purifier can meet the use needs to a certain extent, its disadvantage is that the evaporation base absorbs the heat of the sun to heat and evaporate the water, and the structure of the evaporation base needs to be designed. The water cannot be directly heated by sunlight, which affects the purification efficiency. Utility Model Content

[0006] Preferably, the water collecting tank is arranged transversely inside the water tray.

[0007] Preferably, the number of the Fresnel lenses is nine, and the nine Fresnel lenses are distributed in a matrix on the cover plate.

[0008] Preferably, the solar water purifier further comprises a heating plate, and the heating plate is arranged in the water tray.

[0009] Preferably, the heating plate is connected with a USB cable.

[0010] Preferably, the distance between the Fresnel lens and the bottom of the water tray is smaller than the focal length of the Fresnel lens.

[0011] Compared with the prior art, the beneficial effect of the utility model is that the utility model utilizes sunlight to irradiate and heat the water to be treated through the Fresnel lens, so that the water to be treated evaporates to form water vapor, which then contacts the bottom of the Fresnel lens to form water droplets and then gathers into clean water, which can effectively treat sewage into pure water. The entire water purification process utilizes sunlight to directly act on the water to be treated, which is convenient and fast, and uses solar energy to treat sewage, thereby achieving environmental protection and energy saving.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0018] Example 1

[0019] like Figures 1 to 3As shown, the solar water purifier of this embodiment includes a water tray 1 and a cover plate 2, wherein a water inlet 11 is provided at the lower part of the water tray 1, a water outlet 12 is provided at the upper part of the water tray 1, a Fresnel lens 21 is provided on the cover plate 2, the cover plate 2 is tilted to cover the top of the water tray 1, and a water collecting tank 13 is provided at the front side of the interior of the water tray 1 below the cover plate 2, and the water collecting tank 13 is connected with the water outlet 12. During operation, the water to be treated enters the water tray 1 from the water inlet 11, and the sunlight is irradiated into the water to be treated through the Fresnel lens 21. The water to be treated forms water vapor under the heating of the sunlight, rises to the bottom of the Fresnel lens 21, and then gathers into water droplets, slides down along the Fresnel lens 21 into the water collecting tank 13 to form clean water, and then flows out from the water outlet 12. The solar water purifier of this embodiment utilizes sunlight to irradiate and heat the water to be treated through the Fresnel lens, so that the water to be treated evaporates to form water vapor, which then contacts the bottom of the Fresnel lens to form water droplets and then gathers into clean water. It can effectively treat sewage into pure water. The entire water purification process is convenient and fast. In addition, the use of solar energy to treat sewage achieves environmental protection and energy saving.

[0020] In this embodiment, the water collection tank 13 is arranged horizontally inside the water tray 1 to facilitate the collection of water droplets to form clean water. The number of the Fresnel lenses 21 is nine, and the nine Fresnel lenses 21 are distributed in a matrix on the cover plate 2, so that the water to be treated is heated more evenly as a whole.

[0021] In this embodiment, the solar water purifier further includes a heating plate 3, which is arranged in the water tray 1, and is used for auxiliary heating. The heating plate 3 is connected to a USB cable to facilitate the external power supply of the heating plate 3. The distance between the Fresnel lens 21 and the bottom of the water tray 1 is less than the focal length of the Fresnel lens 21, so as to prevent the heating plate from being burned due to excessively high temperature of sunlight.

[0022] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
