[0032] 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.

[0033] like Figure 1 , Figure 2 The diagram shows an outdoor solar fountain device provided in an embodiment of the present invention. This outdoor solar fountain device can be placed outdoors and provides a drinking and playing area for birds. The outdoor solar fountain device of this embodiment includes a first container 10, a second container 20, and a water spray assembly 30. The first container 10 is fixed to the top of the second container 20, the main body of the water spray assembly 30 is installed in the first container 10, and the other parts are located inside the second container 20.

[0034] Combination Figure 8 As shown, the first container 10 is basin-shaped, such as a round basin, and includes a bathing tub 11 and a first connecting opening 12. The bathing tub 11 is formed on the upper surface of the first container 10, and the first connecting opening 12 is connected to the bathing tub 11. Specifically, the first container 10 can be made of rigid plastic, natural stone, artificial stone, etc., and may include an arc-shaped bottom wall, that is, the first container 10 is an open basin as a whole, and the first connecting opening 12 may be located in the center of the arc-shaped bottom wall. Of course, in practical applications, the first connecting opening 12 may also be off-center from the center of the arc-shaped bottom wall. In addition, to enhance the landscape effect, the outer surface of the first container 10 may have relief patterns, etc.

[0035] Combination Figure 2 , Figure 3 As shown, the second container 20 is cylindrical and includes a water storage cavity 21 and a second connecting port 22 connected to the water storage cavity 21. The volume of the water storage cavity 21 is larger than the volume of the bath tub 11, meaning that under normal conditions, the second container 20 holds more water than the first container 10. Those skilled in the art will understand that under normal conditions, the bath tub 11 of the first container 10 is not filled with water; for example, the water depth in the bath tub 11 is 2.5-5 cm. Similarly, the second container 20 can be made of hard plastic, natural stone, artificial stone, etc., and its cross-section can be circular, i.e., cylindrical. The second connecting port 22 can be located at the center of the top of the second container 20. To improve the decorative effect, the radial dimension of the second container 20 can be different at various axial positions, and the outer wall of the second container 20 can have embossed patterns, etc. Of course, in practical applications, the second connecting port 22 may also be offset from the center of the top of the second container 20.

[0036] Combination Figure 3 As shown, the water spray assembly 30 includes a disc-shaped body 31, a solar panel 32, a filter 33, a nozzle 311, a connecting pipe 34, and a water pump 35. The nozzle 311 is a hollow tubular shape. The solar panel 32 is mounted on the upper surface of the disc-shaped body 31. This solar panel 32 converts sunlight into electrical energy, which directly or indirectly powers the water pump 35. Specifically, the electrical energy for the water pump 35 comes from the solar panel 32. Direct power from the solar panel 35 means that the output of the solar panel 32 is connected to the power input of the water pump 35 via a voltage conversion circuit. Indirect power from the solar panel 35 means that the electrical energy output by the solar panel 35 is first stored in a battery, and the battery then powers the water pump 35. Both the solar panel 32 and the water pump 35 can adopt conventional structures in the art, which will not be described in detail here.

[0037] The second container 20 is fixed below the first container 10 by connecting the second connecting port 22 and the first connecting port 12. That is, the water storage chamber 21 of the second container 20 is connected to the bathing water tank 11 of the first container 10 through the first connecting port 12 and the second connecting port 22. The filter element 33 is placed at the first connecting port 12, and the water in the bathing water tank 11 of the first container 10 flows through the filter element 33 under the action of gravity and then enters the water storage chamber 21. That is, the water in the bathing water tank 11 flows into the water storage chamber 21 after being filtered by the filter element 33. Furthermore, when the water spray assembly 30 is installed in place, the disc-shaped main body 31 and the nozzle 311 are respectively located in the bathing water tank 11 of the first container 10, while the water pump 35 is located in the water storage chamber 21 of the second container 20. The outlet 351 of the water pump 35 is connected to the nozzle 311 via a connecting pipe 34. The connecting pipe 34 passes through the first connecting port 12 and the second connecting port 22. In this way, when the water pump 35 is working, the water in the water storage chamber 21 can be pressurized and transported to the nozzle 311 through the connecting pipe 34, and sprayed out from the nozzle 311 to form a better landscape effect.

[0038] Those skilled in the art will understand that, in order to improve the photoelectric conversion efficiency of the solar panel 32, when the water spray assembly 30 is installed, the solar panel 32 should face upwards and all parts should preferably be at the same horizontal height, and the liquid level in the bathing water tank 11 should preferably be lower than the plane where the solar panel 32 is located. The spray nozzle 311 should preferably be higher than the liquid level in the bathing water tank 11, and a water spout (not shown in the figure) can also be installed on the spray nozzle 311 to further improve its water spraying effect.

[0039] The aforementioned outdoor solar fountain device avoids the need for frequent water addition to the first container 10 by setting a second container 20 with a water storage chamber 21 below the first container 10 with a bathing water tank 11. That is, as long as the water level in the water storage chamber 21 of the second container 20 is higher than the inlet of the water pump 35, the water pump 35 can draw water from the water storage chamber 21 into the bathing water tank 11 of the first container. Furthermore, by adding a filter element 33 between the first container 10 and the second container 20, impurities entering the water storage chamber 21 of the second container 20 are reduced, thereby reducing the probability of the water pump 35 being blocked and affecting the water spray.

[0040] Combination Figure 2 , Figure 8As shown, in one embodiment of this utility model, in the first container 10, the first connecting port 12 is located at the bottom of the first container 10, that is, the first connecting port 12 is located at the bottom of the bathing water tank 11; correspondingly, in the second container 20, the second connecting port 22 is located at the top of the second container 20, that is, the second connecting port 22 is located at the top of the water storage chamber 21. Furthermore, the outdoor solar fountain device includes a base 40, the bottom of the second container 20 is fixed to the base 40, and when the first container 10 and the second container 20 are connected, and the second container 20 is connected to the base 40, the first container 10, the second container 20, and the base 40 are coaxial.

[0041] The above structure can improve the overall landscape effect of the outdoor solar fountain device. Of course, in practical applications, the connection between the first container 10 and the second container 20, and the connection between the second container 20 and the base 40, can also adopt other forms, which will not be elaborated here.

[0042] like Figure 6 As shown, in one embodiment of this utility model, the nozzle 311 of the water spray assembly 30 is integral with the disc-shaped body 31 and located in the center of the disc-shaped body 31. For example, the disc-shaped body 31 and the nozzle 311 are integrally injection molded from plastic or the like. A first annular groove 312 is formed on the upper surface of the disc-shaped body 31, the nozzle 311 is located in the center of the first annular groove 312, and the solar panel 32 is annular and fixed to the first annular groove 312, that is, the shape and size of the solar panel 32 are adapted to the shape and size of the first annular groove 312.

[0043] Those skilled in the art will understand that after the solar panel 32 is installed into the first annular groove 312, transparent adhesive can be injected into the first annular groove 312 to improve the waterproof performance of the solar panel 32 and extend its service life.

[0044] Combination Figure 4 , Figure 5As shown, the filter element 33 includes a box-shaped body 331 and filter cotton 332. The box-shaped body 331 can be made of plastic or other materials, and the filter cotton 332 can be made of porous polyester fiber or other materials. The box-shaped body 331 includes a side plate 3311, a bottom plate 3312, and a cavity 3317 formed by the side plate 3311 and the bottom plate 3312. The cavity 3317 has a top opening, and the box-shaped body 331 is mounted to the disc-shaped body 31 such that the top opening of the cavity 3317 is attached to the lower surface of the disc-shaped body 31. The filter cotton 332 is installed in the cavity 3317, and the side plate 3311 has a first filter hole 3313, and the bottom plate 3312 has a second filter hole 3314. In this way, the water in the bathing tub 11 can enter the chamber 3317 of the box-shaped body 331 through the first filter hole 3313, and after being filtered by the filter cotton 332, it flows out of the chamber 3317 through the second filter hole 3314, thus completing the purification of the water entering the water storage chamber 21 of the second container 20.

[0045] In the aforementioned filter element 33, the first filter hole 3313 on the side plate 3311 can perform preliminary filtration of the water in the bathing water tank 11 to prevent larger objects, such as leaves, from entering the cavity 3317 of the box-shaped body 331. The filter cotton 332 can further filter smaller particles, thereby ensuring that there are fewer impurities in the water entering the water storage cavity 21.

[0046] Specifically, the aforementioned first filter holes 3313 can be longitudinally strip-shaped, thereby preventing impurities such as leaves floating on the surface from clogging the first filter holes 3313 when the liquid level in the bath tub 11 drops to the height of the side plate 3311 of the box-shaped main body 331. Furthermore, the aforementioned side plate 3311 of the box-shaped main body 331 can be annular, with multiple first filter holes 3313 evenly distributed circumferentially on the side plate 3311.

[0047] like Figure 3 As shown, in one embodiment of the present invention, the box-shaped body 331 includes a first segment 3318 and a second segment 3319 connected axially. The radial dimension of the first segment 3318 is greater than the radial dimension of the first connecting port 12, and the radial dimension of the second segment 3319 is adapted to the radial dimension of the first connecting port 12. Correspondingly, the radial dimension of the filter cotton 332 is adapted to the radial dimension of the second segment 3319, and when the water spray assembly 30 is installed in place, the second segment 3319 is inserted into the first connecting port 12.

[0048] The above structure can prevent impurities in the water from entering the water storage chamber 21 through the gap between the box-shaped main body 331 and the first container 10.

[0049] Combination Figure 5 , Figure 7As shown, in one embodiment of this utility model, the outer wall of the top of the side plate 3311 of the box-shaped body 331 of the filter element 33 has a first connecting portion 3315. Correspondingly, the lower surface of the disc-shaped body 31 has a second connecting portion 315, and the box-shaped body 331 is fixed to the disc-shaped body 31 by connecting the first connecting portion 3315 and the second connecting portion 315. For example, the first connecting portion 3315 may have a slot, and the second connecting portion 315 is fixed by embedding into the slot. Furthermore, the box-shaped body 331 may have multiple (e.g., three) circumferentially distributed first connecting portions 3315, and the lower surface of the disc-shaped body 31 also has multiple second connecting portions 315 located on the same circumference.

[0050] The aforementioned box-shaped main body 331 also includes multiple support plates 3316. These support plates 3316 are located below the first section 3318 and surround the second section 3319. When the water spray assembly 30 is installed in place, the support plates 3316 support the bottom of the first container 10, that is, support the bottom wall of the bath water tank 11. Figure 3 As shown. This structure allows the water spray assembly 30 to remain stable.

[0051] Combination Figure 3 , Figure 4 As shown, in one embodiment of this utility model, the connecting pipe 34 includes an intermediate pipe 341 and an extension pipe 342 made of rigid material. The intermediate pipe 341 is integral with the bottom plate 3312 of the box-shaped body 331. When the box-shaped body 331 is installed onto the disc-shaped body 31, the top of the intermediate pipe 341 is connected to the bottom of the nozzle 311, the top of the extension pipe 342 is connected to the bottom of the intermediate pipe 341, and the outlet 351 of the water pump 35 is connected to the bottom of the extension pipe 342. This structure ensures that the water pump 35 can be suspended in the water storage chamber 21 of the second container 20, thereby facilitating the assembly of the water spray assembly 30.

[0052] Combination Figure 2 , Figure 3As shown, in one embodiment of this utility model, the outdoor solar fountain device further includes a first control circuit board 37, a light-emitting module 39, and a battery 38. The light-emitting module 39 includes a second control circuit board 391 and a plurality of light-emitting elements 392 located on the upper surface of the second control circuit board 391. The second control circuit board 391 is mounted on the upper surface of the disc-shaped body 31 with the plurality of light-emitting elements 392 surrounding the nozzle 311, and the orientation of the light-emitting elements 392 is the same as the orientation of the nozzle 311. Specifically, the light-emitting elements 392 can be light-emitting diodes (LEDs). The upper surface of the disc-shaped body 31 has a second annular groove 313, which is located inside the first annular groove 312 and surrounds the nozzle 311. The light-emitting module 39 is installed within the second annular groove 313. Similarly, to improve waterproofing, transparent adhesive can be injected into the second annular groove 313 after the light-emitting module 39 is installed in it.

[0053] Accordingly, the lower surface of the disc-shaped body 31 has a mechanism box 36, in which the first control circuit board 37 and the battery 38 are respectively installed, and the solar panel 32, the second control circuit board 391, and the battery 38 are electrically connected to the first control circuit board 37. Specifically, the disc-shaped body 31 may have a wire hole 314, through which the cable connecting the first control circuit board 37 passes and is electrically connected to the second control circuit board 391 and the solar panel 32. To save space and maintain balance, when the box-shaped body 331 is fixed to the disc-shaped body 31, the aforementioned mechanism box 36 is located inside the box-shaped body 331, and the intermediate tube 341 passes through the mechanism box 36 and is connected to the nozzle 311. Furthermore, to improve waterproof performance, the mechanism box 36 can be sealed or potted with glue.

[0054] Those skilled in the art will understand that the battery 38 is a rechargeable battery, and the first control circuit board 37 may have circuits for charging the battery 38, circuits for powering the water pump 35, circuits for powering the light-emitting module 39, etc. The second control circuit board 391 may have circuits for driving the light-emitting body 392 to emit light, etc. In this way, the electrical energy generated by the solar panel 32 absorbing sunlight is converted by the first control circuit board 37 to charge the battery 38, and the battery 38 supplies power to the water pump 35 and the light-emitting module 39 via the first control circuit board 37. The above circuits can all adopt conventional solutions in the art, and will not be described in detail here.

[0055] Combination Figure 2 , Figure 8As shown, in one embodiment of this utility model, the first connecting port 12 of the first container 10 has a circular cross-section, and the inner wall of the first connecting port 12 is formed with a first internal thread 121. Correspondingly, the top of the second container 20 has a cylindrical first connecting section 23, the second connecting port 22 extends to the first connecting section 23, the outer periphery of the first connecting section 23 is formed with a first external thread 231, and the first container 10 and the second container 20 are fixed together by being threadedly connected by the first internal thread 121 and the first external thread 231, that is, the first connecting section 23 is inserted into the first connecting port 12. Furthermore, in order to improve the sealing effect after the first connecting port 12 and the second connecting port 22 are connected, a sealing ring 51 can be added between the bottom of the first container 10 and the top of the second container 20.

[0056] Similarly, the bottom of the second container 20 has a cylindrical second connecting section 24, and the outer periphery of the second connecting section 24 is formed with a second external thread 241; the top of the base 40 has a connecting groove 411 with a circular cross-section, the inner wall of the connecting groove 411 is formed with a second internal thread 412, and the base 40 and the second container 20 are fixed together by means of threaded connection between the second internal thread 412 and the second external thread 241, that is, the second connecting section 24 is inserted into the connecting groove 411.

[0057] Specifically, the aforementioned base 40 can be composed of a base 42 and a support column 41, thereby increasing the overall height of the aforementioned outdoor solar fountain device. Similarly, the bottom of the support column 41 has a cylindrical third connecting section 413, and the outer periphery of the third connecting section 413 has a third external thread. Correspondingly, the base 42 has a connecting groove 421 with a circular cross-section, and the inner wall of the connecting groove 421 forms a third internal thread. The base 42 and the support column 41 are fixed together by means of a threaded connection between the third internal thread and the third external thread, that is, the third connecting section 413 is inserted into the connecting groove 421. In some cases, the second connecting section 24 of the second container 20 can be directly fixed to the connecting groove 421 of the base 42 to reduce the height of the first container 10.

[0058] like Figure 8 As shown, in one embodiment of this utility model, the bottom wall of the bathing water tank 11 of the first container 10 is arc-shaped, and the bottom wall of the bathing water tank 11 has a plurality of grooves 13, and at least some of the grooves 13 are fitted with copper sheets 14. The copper sheets 14 can slowly release copper ions under the action of water in the bathing water tank 11, thereby inhibiting the reproduction of microorganisms in the water, such as moss or algae.

[0059] 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.
