Birdbaths serve not only as practical ecological features but often also as landscape features that attract birds.

[0003] To increase their appeal, some birdbaths are equipped with fountain mechanisms. However, since these installations are exposed to the elements, debris such as leaves and bird droppings easily accumulate in the basin, frequently clogging the fountain pump and thus impairing its operation. To avoid startling smaller birds, existing birdbaths typically have a water depth of 2.5 to 5 cm. This limited water capacity necessitates frequent refilling. Subject of the utility model

[0004] The technical problem solved by this utility model is to provide a solar-powered outdoor fountain device that solves the problems of pump clogging and the limited water storage capacity of conventional bird baths.

[0005] The technical solution to the aforementioned technical problems is to provide a solar-powered outdoor fountain device that includes the following: An open-topped container, which is basin-shaped and includes a bathtub and a first connecting opening; the bathtub is formed on the top of the container, and the first connecting opening is connected to the bathtub; a support column which is column-shaped and includes a water storage cavity and a second connecting opening which is connected to the water storage cavity, wherein the volume of the water storage cavity is larger than that of the bathtub; A spraying device comprising a disc-shaped body, a solar panel, a filter element, a spray nozzle, connecting pipes and a water pump driven directly or indirectly by the solar panel, wherein the solar panel is mounted on the top of the disc-shaped body; The support column is attached below the open-topped container so that its second opening connects to the first. The filter element is positioned at the first opening, and the water from the bathtub flows through the filter element before entering the water reservoir. When the sprayer is installed, the disc-shaped body and spray nozzle are located inside the bathtub of the open-topped container, while the water pump is located inside the water reservoir chamber. The water pump outlet is connected to the spray nozzle via a connecting pipe that passes through both the first and second ports.

[0006] The present utility model offers the following advantageous effects: By positioning a support column with a water storage cavity below the open-topped container with a bathtub and by installing a filter element between the open-topped container and the support column, not only is the need for frequent refilling of water into the open-topped container eliminated, but also clogging of the pump, which could impair the spray performance, is prevented.

[0007] To clarify and explain the objectives, technical solutions, and advantages of this utility model, the following detailed description is given with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described here serve only to illustrate this utility model and are not intended to limit its scope.

[0008] As in the Fig. 1 and Fig. Figure 2 shows a schematic diagram of the outdoor solar fountain provided by an embodiment of the present utility model. This outdoor solar fountain can be placed outdoors to provide birds with a place to drink and play. The solar-powered outdoor fountain of this embodiment comprises an open-topped container 10, a support column 20, and a water spray device 30. The open-topped container 10 is attached to the top of the support column 20, with the main body of the water spray device 30 located inside the open-topped container 10, while other components are located inside the support column 20.

[0009] As in Fig. As shown, the aforementioned open-topped container 10 has a basin-like configuration, for example, a circular basin, and comprises a bathtub 11 and a first connecting opening 12. The bathtub 11 is formed on the top of the open-topped container 10, with the first connecting opening 12 connected to it. In particular, the open-topped container 10 can be made of rigid plastic, natural stone, artificial stone, or similar materials. It can have a curved bottom wall, so that the open-topped container 10 as a whole forms an open basin, with the first connecting opening 12 located centrally on the curved bottom wall. Of course, in practical application, the first connecting opening 12 can also be offset from the center of the curved bottom wall. To enhance the aesthetic effect, the outer surface of the open-topped container 10 can additionally be provided with relief patterns or similar decorative elements.

[0010] As in the Fig. 2 and Fig. As shown in Figure 3, the support column 20 has a column-like shape. It includes a water storage chamber 21 and an associated second connection port 22. The volume of the water storage chamber 21 exceeds that of the bathing basin 11, so that, under normal conditions of the open-topped container 10 and the support column 20, the amount of water contained in the support column 20 exceeds the amount of water contained in the open-topped container 10. As is known to those skilled in the art, the bathing basin 11 of the open container 10 is not filled to the brim under normal conditions; for example, the water depth in the bathing basin 11 is between 2.5 and 5 cm. Likewise, the support column 20 can be made of rigid plastic, natural stone, artificial stone, etc., and its cross-section can be circular, meaning that the support column 20 can have a cylindrical shape, with the second connection port 22 positioned centrally at the top of the support column 20.To enhance the decorative effect, the radial dimensions of the support column 20 can vary at different axial positions, and its outer wall can be decorated with embossed patterns or similar ornamentation. Naturally, in practical applications, the second connecting opening 22 can be offset from the center point of the top of the support column 20.

[0011] As in Fig. As shown, the water spray device 30 comprises a disc-shaped main body 31, a solar panel 32, a filter element 33, a nozzle 311, a connecting pipe 34, and a water pump 35. The nozzle 311 is hollow and tubular. The solar panel 32 is mounted on the top of the disc-shaped body 31. This solar panel 32 converts sunlight into electrical energy and supplies the water pump 35 with power directly or indirectly, meaning that the electrical energy for operating the water pump 35 originates from the solar panel 32. Direct power supply to the water pump 35 by the solar panel 32 means that the output of the solar panel is connected to the power input terminal of the pump via a voltage converter circuit.The indirect power supply of the water pump 35 via the solar panel 32 means that the electrical energy generated by the solar panel is first stored in a battery, which then supplies power to the water pump 35. Both the solar panel 32 and the water pump 35 can use conventional structures within the prior art, and further description is omitted here.

[0012] The support column 20 is attached below the open-topped container 10 such that its second connection port 22 is connected to the first connection port 12. This means that the water storage chamber 21 of the support column 20 is connected to the bath water tank 11 of the open-topped container 10 via both the first connection port 12 and the second connection port 22. The filter element 33 is positioned at the first connection port 12. The water in the bath water tank 11 of the open-topped container 10 flows by gravity through the filter element 33 before entering the water storage chamber 21. In other words, the water from the bath water tank 11 is filtered by the filter element 33 before flowing into the water storage chamber 21.When the spray arrangement 30 is installed in position, the disc-shaped body 31 and the spray nozzle 311 are each located within the basin 11 of the open-topped container 10, while the water pump 35 is located within the water storage chamber 21 of the support column 20. The outlet 351 of the water pump 35 is connected to the spray nozzle 311 via the connecting pipe 34. The aforementioned connecting pipe 34 passes through the first connecting port 12 and the second connecting port 22. When the water pump 35 is operating, the water from the water storage chamber 21 is pressurized and conveyed through the connecting pipe 34 to the spray nozzle 311, where it is expelled to produce an enhanced visual effect.

[0013] As experts know, to increase photovoltaic conversion efficiency, the solar panel 32 should point upwards when the water spray arrangement 30 is installed, with all sections ideally lying on the same horizontal plane. Furthermore, the liquid surface within the bath 11 should ideally be below the plane on which the solar panel 32 is located. The nozzle 311 is preferably positioned above the liquid surface within the bath 11. Additionally, a water outlet (not shown in the figure) can be installed on the nozzle 311 to further enhance its water spray effect.

[0014] The aforementioned outdoor solar fountain device avoids the need for frequent refilling of the open-topped container 10 by positioning a support column 20 with a water storage chamber 21 below the open-topped container 10, which contains the bath 11. Specifically, the water level in the water storage chamber 21 of the support column 20 remains above the inlet of the water pump 35. The pump 35 can then pump water from the storage chamber 21 into the bath 11 of the open-topped container. Furthermore, the installation of a filter element 33 between the open-topped container 10 and the support column 20 reduces impurities entering the storage chamber 21 of the support column 20, thereby decreasing the likelihood of the pump 35 becoming clogged and its spray performance being impaired.

[0015] As in the Fig. 2 and Fig. As shown in Figure 8, in one embodiment of the present utility model, the first connecting opening 12 is located at the bottom of the aforementioned open container 10, meaning that the first connecting opening 12 is located at the bottom of the bathtub 11. Similarly, the second connecting opening 22 is located at the top of the support column 20, i.e., the second connecting opening 22 is located at the top of the water storage cavity 21. Furthermore, the aforementioned outdoor solar fountain device includes a base 40, the bottom of which is attached to the base 40. When the open-topped container 10 is connected to the support column 20, and the support column 20 is connected to the base 40, the open-topped container 10, the support column 20, and the base 40 are coaxial.

[0016] This configuration improves the overall aesthetics of the outdoor solar fountain device. Of course, alternative configurations for connecting the open-topped container 10 to the support column 20 and the support column 20 to the base 40 can also be used in practice, but these will not be discussed in detail here.

[0017] As in Fig. As shown, in one embodiment of the present utility model, the nozzle 311 of the aforementioned water spray device 30 is integrally formed with the disc-shaped body 31 and positioned in its center. For example, the disc-shaped body 31 and the nozzle 311 can be integrally injection-molded from plastic or a similar material. The top surface of the disc-shaped body 31 forms a first annular groove 312. The nozzle 311 is positioned in the center of the first annular groove 312, and the solar panel 32 is attached in an annular form within the first annular groove 312. That is, the shape and dimensions of the solar panel 32 are adapted to the shape and dimensions of the first annular groove 312.

[0018] As experts know, after the solar panel 32 has been installed in the first annular groove 312, transparent adhesive can be poured into the first annular groove 312 to improve the water resistance of the solar panel 32 and to extend its service life.

[0019] As in the Fig. 4 and Fig. As shown in Figure 5, the aforementioned filter arrangement 33 comprises a box-shaped body 331 and filter wool 332. The box-shaped body 331 can be made of plastic materials, while the filter wool 332 can be made of porous polyester fibers or similar materials. The box-shaped body 331 comprises side walls 3311, a base plate 3312, and a chamber 3317 enclosed by the side walls 3311 and the base plate 3312. This chamber 3317 is open at the top, and the box-shaped body 331 is mounted on the disc-shaped body 31, with the open top of the chamber 3317 resting against the underside of the disc-shaped body 31. The filter wool 332 is installed in the chamber 3317, with the side wall 3311 having a first filter opening 3313 and the base plate 3312 having a second filter opening 3314.Thus, water from the bathtub 11 can enter the chamber 3317 of the box-shaped body 331 through the first filter opening 3313, be filtered through the filter wool 332 and then exit the chamber 3317 through the second filter opening 3314, thereby completing the cleaning of the water entering the water storage space 21 of the support column 20.

[0020] Within the aforementioned filter arrangement 33, the first filter opening 3313 on the side wall 3311 pre-filters the water from the bathtub 11 and prevents larger objects such as leaves from entering the chamber 3317 of the box-shaped main body 331. The filter wool 332 then further filters out smaller particles, thus ensuring that the water entering the water storage chamber 21 contains as few impurities as possible.

[0021] In particular, the aforementioned first filter holes 3313 can be configured as longitudinal strips. This design prevents floating contaminants such as leaves from clogging the first filter holes 3313 when the liquid level in the bath water tank 11 drops to the level of the side plate 3311 of the box-shaped main body 331. Furthermore, the side plate 3311 of the box-shaped body 331 can be annular, with several first filter holes 3313 evenly distributed around the circumference of the side plate 3311.

[0022] As in Fig. As shown in Figure 3, the aforementioned box-shaped body 331, in one embodiment of the present utility model, comprises an axially connected first segment 3318 and a second segment 3319. The radial dimension of the first segment 3318 exceeds that of the first connection opening 12. The radial dimension of the second segment 3319, on the other hand, is designed to correspond to that of the first connection opening 12. Similarly, the radial dimension of the filter wool 332 is matched to that of the second segment 3319. When the spray device 30 is positioned, the second segment 3319 is inserted into the first connection opening 12.

[0023] This configuration prevents impurities in the water from entering the water storage chamber 21 through the gap between the box-shaped body 331 and the open-topped container 10.

[0024] As in the Fig. 5 and Fig. In one embodiment of the present utility model, the outer wall on the upper side of the side plate 3311 of the box-shaped body 331 of the aforementioned filter element 33 has a first connecting section 3315. Similarly, the underside of the disc-shaped body 31 has a second connecting section 315. The box-shaped body 331 is attached to the disc-shaped body 31 by connecting the first connecting section 3315 to the second connecting section 315. For example, the first connecting section 3315 can have a snap-lock groove, with the second connecting section 315 securing the assembly by engaging in the groove. Furthermore, the box-shaped body 331 can have several (e.g.,three) have circumferentially distributed first connecting sections 3315, while the underside of the disc-shaped body 31 similarly has several second connecting sections 315 positioned along the same circumference.

[0025] The box-shaped body 331 further comprises several support plates 3316. These support plates 3316 are positioned below the first section 3318 and surround the second section 3319. When the spray device 30 is installed in place, the support plates 3316 rest against the underside of the open container 10, i.e., against the bottom wall of the tub 11, as shown in Fig. Figure 3 shows this configuration. This configuration allows the spray arrangement 30 to remain stable.

[0026] As in the Fig. As shown, in one embodiment of the present utility model, the aforementioned connecting pipe 34 comprises an intermediate pipe 341 and an extension pipe 342, both made of rigid material. The intermediate pipe 341 is formed integrally with the base plate 3312 of the box-shaped body 331. When the box-shaped body 331 is mounted onto the disc-shaped body 31, the top of the intermediate pipe 341 connects to the bottom of the spray head 311, the top of the extension pipe 342 connects to the bottom of the intermediate pipe 341, and the outlet 351 of the water pump 35 connects to the bottom of the extension pipe 342. This configuration ensures that the water pump 35 is suspended within the water storage chamber 21 of the support column 20, thereby facilitating the assembly of the water spray device 30.

[0027] With reference to the Fig. 2 and Fig. In one embodiment of the present utility model, the aforementioned solar-powered outdoor fountain device further comprises a first control board 37, a light emission module 39, and a battery 38. The light emission module 39 comprises a second control board 391 and several light emission elements 392 arranged on the top surface of the second control board 391. The second control board 391 is mounted on the top surface of the disc-shaped body 31 such that the several light emission elements 392 surround the nozzle 311, the orientation of the light emission elements 392 being aligned with that of the nozzle 311. In particular, the light emission elements 392 can use light-emitting diodes (LEDs). The top surface of the disc-shaped body 31 has a second annular groove 313 located within the inner circumference of the first annular groove 312 and surrounding the nozzle 311. The light-emitting module 39 is mounted in this second annular groove 313.To improve water resistance, after installing the light module 39 into the second annular groove 313, transparent adhesive can be poured into the second annular groove 313.

[0028] Accordingly, the underside of the disc-shaped body 31 has a movement space 36. The first control board 37 and the battery 38 are each mounted in this movement space 36. The solar panel 32, the second control board 391, and the battery 38 are each electrically connected to the first control board 37. In particular, the disc-shaped body 31 can have a cable entry opening 314 through which the cable connecting the first control board 37 passes to establish an electrical connection with the second control board 391 and the solar panel 32. To save space and maintain balance, when the box-shaped body 331 is attached to the disc-shaped body 31, the aforementioned mechanism housing 36 is positioned inside the box-shaped body 331, with the intermediate tube 341 passing through the mechanism housing 36 to connect to the spray nozzle 311.To improve water resistance, the mechanism housing 36 can also be sealed with adhesive or potted.

[0029] As experts know, battery 38 is a rechargeable battery. The first control board 37 can contain, among other things, circuits for charging battery 38, supplying power to the water pump 35, and supplying power to the light module 39. The second control board 391 can contain circuits for controlling the light source 392 to emit light. Thus, the electrical energy generated by the absorption of sunlight by the solar panel 32 is converted by the first control board 37 to charge battery 38. Battery 38 then supplies power to the water pump 35 and the light module 39 via the first control board 37. All these circuits can use conventional solutions within the state of the art and are not described in detail here.

[0030] With reference to the Fig. 2 and Fig. In one embodiment of the present utility model, the cross-section of the first connecting opening 12 of the open-topped container 10 is circular, and the inner wall of the first connecting opening 12 is provided with a first internal thread 121. Correspondingly, the top of the support column 20 has a cylindrical first connecting segment 23, with the second connecting opening 22 extending into the first connecting segment 23. The outer circumference of the first connecting segment 23 is provided with a first external thread 231. The open-topped container 10 and the support column 20 are connected to each other by a threaded connection between the first internal thread 121 and the first external thread 231, with the first connecting segment 23 being inserted into the first connecting opening 12.To improve the sealing effect after connecting the first connection port 12 and the second connection port 22, a sealing sleeve 51 can also be installed between the bottom of the open container 10 and the top of the support column 20.

[0031] Similarly, the base of the support column 20 has a cylindrical second connecting section 24, the outer circumference of which forms 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 which forms a second internal thread 412. The base 40 and the support column 20 are connected to each other by a 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.

[0032] In particular, the aforementioned base 40 can include a foundation 42 and a support column 41, thereby increasing the overall height of the outdoor solar fountain device. Similarly, the base of the support column 41 has a cylindrical third connection section 413, the outer circumference of which has a third external thread. Correspondingly, the base 42 has a connection slot 421 with a circular cross-section, the inner wall of which forms a third internal thread. The base 42 and the support column 41 are connected to each other via a screw connection with a third internal and a third external thread, with the third connection segment 413 being inserted into the connection slot 421. In certain scenarios, the second connection segment 24 of the support column 20 can be attached directly to the connection groove 421 of the base 42 to reduce the height of the open-topped container 10.

[0033] As in Fig.As shown in Figure 8, in one embodiment of the present utility model, the bottom wall of the bathwater tank 11 of the aforementioned open container 10 is arcuate, and the bottom wall of the bathwater tank 11 comprises a plurality of grooves 13, with copper plates 14 being installed in at least a portion of the grooves 13. The aforementioned copper plates 14 can slowly release copper ions under the influence of water within the bath 11, thereby inhibiting the growth of microorganisms in the water, such as moss or algae.

[0034] The foregoing description represents only one preferred embodiment of the present utility model. However, the scope of protection of the present utility model is not limited thereto. Any variation or substitution that is readily conceivable to a person skilled in the art within the scope of the technical information disclosed herein falls within the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model is determined by the scope of the claims.
