[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figure 1 The diagram shown is an exploded view of the floating solar fountain provided in this embodiment of the invention. This floating solar fountain can be placed in outdoor water bodies (such as bird baths or landscape pools) and achieve water spraying and other landscape effects. The floating solar fountain of this embodiment includes a solar panel assembly 10, a floating body 20, a battery 30, a control circuit board 40, and a water pump assembly. The overall density of the solar panel assembly 10, the floating body 20, the battery 30, the control circuit board 40, and the water pump assembly is less than the density of water, allowing the floating solar fountain to float on the water surface by its own buoyancy and preventing it from sinking without a supporting structure. Specifically, the floating body 20 can be made of foam with a density less than water, such as PU foam or XPE / IXPE foam. The floating solar fountain primarily relies on the floating body 20 for buoyancy.

[0023] The aforementioned solar panel assembly 10 includes a base 11, a solar panel 12, and a first light assembly 13. The main body of the base 11 can be made of a rigid polymer material (such as engineering plastic), and the base 11 constitutes the installation platform for the floating solar fountain. The float 20, battery 30, control circuit board 40, and water pump assembly are respectively installed (directly or indirectly) below the base 11, while the solar panel 12 and the first light assembly 13 are respectively installed on the upper surface of the base 11. When the floating solar fountain is placed in the water, the upper surface of the base 11 is exposed above the water surface, and the lower surface is below the water surface. That is, when the floating solar fountain is placed in the water, the solar panel 12 and the first light assembly 13 are above the water surface, while the float 20, battery 30, control circuit board 40, and water pump assembly are all or partially below the water surface.

[0024] like Figure 2 As shown, the solar panel 12, the first lamp assembly 13, the battery 30, and the water pump assembly are electrically connected to the control circuit board 40. The control circuit board 40 integrates a charging circuit, a water pump drive circuit, and a first light-emitting drive circuit. When the solar panel 12 is exposed to sunlight, it outputs current to the charging circuit on the control circuit board. The charging circuit converts the current output by the solar panel 12 and stores it in the battery 30. The water pump drive circuit, powered by the battery 30, drives the water pump assembly to draw water from below the base 11, pressurize it, and then spray it out through its nozzle. The first light-emitting drive circuit, powered by the battery 30, drives the first lamp assembly 13 to emit light. Furthermore, the control circuit board 40 may also integrate control logic to make the water pump drive circuit and the first light-emitting drive circuit operate according to preset times and preset methods, such as controlling the water pump drive circuit and the first light-emitting drive circuit to drive the water pump assembly and the first lamp assembly 13 to emit light at night. The aforementioned control circuit board 40 (including integrated charging circuit, water pump drive circuit, first light-emitting drive circuit and control logic), first lamp group 13, battery 30 and water pump assembly can all adopt conventional technologies in the field, and will not be described in detail here.

[0025] Combination Figure 3 , Figure 4 As shown, the base 11 has a first through hole 114. The water pump assembly includes a water pump body 51. The nozzle of the water pump body 51 protrudes from the base 11 through the first through hole 114. Specifically, the nozzle of the water pump body 51 can extend above the base 11 through the first through hole 114, or be embedded in the first through hole 114, or be located below the base 11 and directly opposite the first through hole 114. Under the control of the control circuit board 40, the water pump body 51 can pressurize the water it draws in and spray it upwards above the base 11. In addition, to improve the spraying effect, a nozzle 52 can also be installed on the nozzle of the water pump body 51. The nozzle 52 can make the water flow pattern sprayed from the nozzle more diversified.

[0026] The first lamp assembly 13 includes a plurality of first light-emitting elements 131, which are located on the upper surface of the base 11 and arranged around the first through hole 141. When the first light-emitting elements 131 are in operation, they emit light towards the water sprayed from the nozzle of the water pump assembly. Those skilled in the art will understand that the first light-emitting elements 131 can be light-emitting diodes (i.e., LED beads), and the light emitted by the first light-emitting elements 131 can illuminate both the water sprayed from the nozzle in the upward phase and the water sprayed from the nozzle in the downward phase.

[0027] Specifically, the first light-emitting elements 131 of the first light group 13 emit at least three different colors, thereby making the water sprayed by the floating solar fountain appear in different colors, greatly enhancing the landscape effect. For example, the first light group 13 may include eight first light-emitting elements 131, and the eight first light-emitting elements 131 emit different colors.

[0028] The aforementioned floating solar fountain, by incorporating multiple first light-emitting elements 131 and illuminating the water sprayed from the nozzles of the water pump assembly, produces dazzling colors in the sprayed water, greatly enhancing the visual appeal of the floating solar fountain. Furthermore, since the water pump assembly and the first light-emitting elements 131 are electrically driven by the solar panels 12, no external power supply is required, making it not only hygienic and environmentally friendly but also convenient to use.

[0029] In one embodiment of this utility model, the solar panel assembly 10 further includes a second lamp group 15 electrically connected to the control circuit board 40. The second lamp group 15 includes a plurality of second light emitters 151 surrounding the base 11 and adjacent to the edge of the base 11, and the second light emitters 151 emit light away from the base 11 when in operation. Accordingly, a second light-emitting driving circuit is integrated on the control circuit board 40, which can drive the second lamp group 15 to emit light under the power provided by the battery 30.

[0030] Those skilled in the art will understand that the second light-emitting body 151 can also be a light-emitting diode (i.e., an LED bead), and since the base 11 floats on the water surface, the light generated by the second light-emitting body 151 can illuminate the water surface.

[0031] Specifically, the light emitted by the multiple second light-emitting elements 151 of the second light group 15 includes at least three different colors, thereby making the water surface around the floating solar fountain appear in different colors and further enhancing the landscape effect. For example, the second light group 15 may include more than ten second light-emitting elements 151, and these second light-emitting elements 151 may emit more than seven colors.

[0032] In one embodiment of this utility model, the solar panel assembly 10 further includes a transparent waterproof layer 14, which covers the solar panel 12 and the first lamp group 13. The transparent waterproof layer 14 has a second through hole 141 corresponding to the first through hole 114, allowing the water nozzle of the water pump body 51 to be exposed through the second through hole 141. This allows the water sprayed by the water pump body 51 to reach above the transparent waterproof layer 14. The transparent waterproof layer 14 isolates the solar panel 12 and the first lamp group 13 from the water sprayed by the water pump body 51, thereby preventing short circuits and improving safety. Those skilled in the art will understand that the transparent waterproof layer 14 can be made of a material with good light transmittance, thus not affecting the sunlight shining on the solar panel 12, nor affecting the light from the first lamp group 13 illuminating the water sprayed above the transparent waterproof layer 14.

[0033] Specifically, the thickness of the aforementioned transparent waterproof layer 14 can be around 0.5-2mm, thereby ensuring its light transmittance while maintaining structural strength and preventing it from easily breaking and affecting its waterproof performance.

[0034] In one embodiment of this utility model, the base 11 includes a base plate 111, a first protruding ring 112, and a second protruding ring 113, wherein the second protruding ring 113 is made of a transparent or translucent material (or the base 11 as a whole is made of a transparent or translucent material). The bottoms of the first protruding ring 112 and the second protruding ring 113 are respectively connected to the base plate 111, and the tops of the first protruding ring 112 and the second protruding ring 113 respectively protrude from the upper surface of the base plate 111. The first protruding ring 112 surrounds the first through hole 114, and the second protruding ring 113 surrounds the outer edge of the base plate 111. Specifically, the base plate 111, the first protruding ring 112, and the second protruding ring 113 can be an integral structure, for example, the base plate 111, the first protruding ring 112, and the second protruding ring 113 can be integrally injection molded.

[0035] The transparent waterproof layer 14 can be composed of a transparent polymer adhesive (such as polyvinyl butyral, polyurethane, etc.) injected between the first convex ring 112 and the second convex ring 113. Specifically, the transparent waterproof layer 14 can be injected onto the upper surface of the base plate 111 after the solar panel 12 and the first lamp assembly 13 are installed on the base plate 111, thereby completely enveloping the solar panel 12 and the first lamp assembly 13 and improving waterproof performance. Furthermore, the top surface of the transparent waterproof layer 14 is flush with the top of the first convex ring 112 and the second convex ring 113. Of course, in practical applications, the transparent waterproof layer 14 can also adopt other structures, such as being bonded to the top of the base plate 111 by a transparent plate.

[0036] In addition, the base plate 111 may have multiple slots corresponding to the solar panel 12 and the first lamp group 13 respectively. The solar panel 12 and the first lamp group 13 are respectively installed in their respective slots, thereby improving the installation accuracy of the solar panel 12 and the first lamp group 13.

[0037] In one embodiment of this utility model, the first lamp group 13 further includes a first lamp plate 132 attached to the upper surface of the base plate 111 and surrounding the first convex ring 112, a first light-emitting body 131 located on the upper surface of the first lamp plate 132, and the upper surface of the first lamp plate 132 is parallel to the upper surface of the base plate 111; a solar panel 12 is located on the upper surface of the base plate 111 and surrounds the first lamp plate 132; and a plurality of second light-emitting bodies 151 of the second lamp group 15 are located inside the second convex ring 113. That is, the first lamp group 13 is located on the innermost side of the base plate 111, the solar panel 12 is located in the middle of the base plate 111, and the second lamp group 15 is located on the outermost side of the base plate 111.

[0038] like Figure 3 , Figure 4 As shown, in one embodiment of this utility model, the edge of the base plate 111 has a third protruding ring 115, and the third protruding ring 115 extends downward from the edge of the base plate 111. The bottom of the second protruding ring 113 is connected to the bottom of the third protruding ring 115, and a mounting groove 116 is formed between the third protruding ring 115 and the second protruding ring 113. The second lamp group 15 includes a ring-shaped second lamp plate 152 (for example, the second lamp plate 152 may be made of a flexible circuit board, and the second lamp group 15 may be made of an LED light strip). The second light emitter 151 is located on the outer surface of the second lamp plate 152, and the angle between the second protruding ring 113 and the upper surface of the base plate 111 is 80-90°. The second lamp plate 152 is mounted in the mounting groove 116 with the second light emitter 151 facing the second protruding ring 113, that is, the angle between the second lamp plate 152 and the upper surface of the base 111 is about 90°. Furthermore, the transparent waterproof layer 14 covers the mounting groove 116, meaning the second lamp assembly 15 is also sealed by the transparent waterproof layer 14. This structure greatly facilitates the installation of the second lamp assembly 15.

[0039] In one embodiment of this invention, the base 11 is disc-shaped (i.e., the base plate 111 is circular), and the first through hole 114 is located in the center of the base 11. This structure facilitates the stable floating of the floating solar fountain on the water surface, especially on circular water surfaces (e.g., bird baths). Simultaneously, the circular base 11 also enhances its aesthetic appeal to some extent. Furthermore, to further improve the landscape effect, the edge of the base 11 (i.e., the second convex ring 113) can be wavy.

[0040] In one embodiment of this invention, the floating body 20 is annular, and its upper surface is attached to the lower surface of the base 11. The main components of the battery 30, control circuit board 40, and water pump assembly are all located within the inner ring of the floating body 20. This structure ensures that the center of gravity of the entire floating solar fountain is in the center, facilitating its stable floating on the water surface.

[0041] Specifically, the base 11 may also have a sealing chamber 61 and a sealing cover plate 62 below it. The sealing chamber 61 avoids the first through hole 114 and is located in the inner ring of the float 20. A receiving cavity is formed between the sealing chamber 61 and the sealing cover plate 62, and the battery 30 and the control circuit board 40 are both installed in this receiving cavity. The above structure facilitates the sealed installation of the battery 30 and the control circuit board 40.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
