Description

Fountain device

Technical Field

The invention relates to a fountain device, in particular to a fountain device with an illumination mechanism.

Background

CN206504207U discloses a fountain lamp, comprising a shell and a water pipe barrel penetrating through the center of the shell; the shell is a cylindrical shell with an upper opening, the shell comprises an upper shell and a lower shell, and the upper end and the lower end of the water pipe barrel extend out of the upper shell and the lower shell respectively; fixing holes are uniformly distributed on the side walls of the upper side and the lower side of the water pipe barrel, and connecting rods for fixing are arranged on the fixing holes; a plurality of screw holes are correspondingly and uniformly distributed on the outer edges of the circumferences of the upper shell and the lower shell, so that the upper shell and the lower shell can be fastened and connected through screws. The upper shell and the lower shell are provided with screw holes, so that the fixing is tighter, and the structure is stronger and more reliable. The large-area illumination of the fountain landscape is realized, and the illumination of higher light beams can be realized. However, the present invention has a problem in that the main buoyancy-providing member is a hard case, which occupies a large space when not in use, and is inconvenient to store.

Disclosure of Invention

In view of the shortcomings of the prior art, the independent claims of the present invention provide a fountain device, the dependent claims recite preferred improvements thereof.

In contrast to the float formed by the rigid housing, the fountain apparatus of the present invention has a plurality of water jets circumferentially distributed along the top surface. These jets spray water radially outward and simultaneously create upward and radially outward forces, so that the reaction force of the forces has not only a vertical component, but also a horizontal component that will push the fountain apparatus of the present invention to move on the water surface. In terms of the volume to weight ratio, the floating part is lighter and is further easily influenced by water surface fluctuation, and the up-and-down fluctuation of the water surface strengthens the change of the water spraying direction of the water spraying port, so that the fountain device moves on the water surface.

In addition, the advantages are as follows:

1. the floating part forms an inflatable floating structure by injecting low-density fluid and is installed with the machine core in a split mode, so that when the fountain device is not used, the floating part in an inflated state can be in a foldable mode by discharging the low-density fluid, and workers can conveniently store and carry the fountain device.

2. The float may be made of a flexible material, and its flexible mounting duct may also be flexible. Therefore, the movement mounting duct formed when the float is inflated can be adapted to the fountain movement and can remain in particular clamped to the fountain movement; secondly, the flexible movement mounting pore canal has deformability, which is beneficial to generating horizontal movement by means of reaction force.

3. The movement mounting hole has a certain hole length and a certain section shape, so that the fountain movement can slide through the floating part or rotate in the floating part during mounting, and the reaction force generated during water spraying can enable the fountain device to move.

4. The float is inflated by injection of a low density fluid. The low density fluid assists the fountain assembly in at least partially invading the external liquid.

5. The injected low-density fluid is optional, and the low-density fluid with different densities can form disordered motions with different swing amplitudes and different intensity, so that a user can inject different low-density fluids through the injection interface on the floating part through different scenes. For example, for unordered movements with large swing amplitudes, the injection of gas may be selected; for unordered movements with slight swing amplitude, alcohol can be injected selectively; in the present invention, the low-density fluid means a fluid having a density less than or equal to that of the external fluid. For example, the external fluid is water, then the density of the low density fluid is less than that of water, e.g., the low density fluid may be air, an inert gas, nitrogen, alcohol, or gasoline, etc.; of course, water itself is also possible.

6. In the disordered process, the fountain machine core and the fountain machine core pore canal have interaction force. The flexible fountain core pore canal has excellent vibration absorption and deformation functions, so that the hydraulic device and the power supply device inside the fountain core can be effectively protected when the fountain core collides with the core installation pore canal, and the hard floating shell and the fountain core in the prior art can cause damage to the internal device and the shell of the fountain core;

7. the volume of the low-density fluid injection can be determined according to the scene, and if the water jet of the fountain device is required to be exposed on the water surface, the whole floating part can be filled; if it is desired that the water jet portion of the water jet device is submerged, a small amount of low density fluid may be injected into the float. The fountain device which can be almost submerged in water and emit light according to the present invention can bring about a color-changing globefree effect at night with respect to the structure of the hard casing.

Preferably, the float has an interface for connecting the fountain cartridge such that in the case of a fountain cartridge mounted to the cartridge mounting aperture. The fountain device can float on the water surface in a way that the geometric center or the geometric gravity center of the fountain device penetrates through the mounting pore canal of the movement. The arrangement has the advantages that: 1. the interface has a guiding function, so that the fountain movement is convenient to install; 2. the interface has the function of fixedly installing the fountain core; 3. because the geometric center or the geometric center of gravity of the fountain device is positioned in the movement mounting pore canal, the fountain device is helped to generate disordered movement but cannot generate violent movement, so that a user misuses the fountain device to have mechanical faults; 4. the structural length of the movement installation pore canal can meet the gravity center or geometric center of the fountain device and penetrate through the movement installation pore canal. Since the float of flexible material is significantly lighter than the fountain movement, the center of gravity of the fountain device is determined by the fountain movement. Thus, the center of gravity can be adjusted by adjusting the distance of the water pump from the plane of the water jet and/or the battery mounting position. For example, when the water pump is adjusted to be close to the water jet, the gravity center of the fountain device is close to the water jet, so that the swing amplitude of the fountain device is effectively limited; the water pump is arranged close to the water suction port, so that the gravity center of the fountain device is close to the lower side, and the swing amplitude of the fountain device is effectively limited. 5. The center of gravity or geometric center of the fountain device is also dependent on the type and volume of the injected low density fluid, so the center of gravity and/or geometric center of the fountain device can be adjusted by adjusting the type and volume of the injected fluid.

Preferably, the fountain device is capable of producing a disordered motion in the horizontal direction on the water surface by virtue of the dynamically changing resultant forces during the hydraulic section delivering at least a portion of the water entering the water inlet of the hydraulic section to the water jet to form the fountain. Preferably, the plurality of water jets are arranged on the top surface of the fountain core in such a way that the different arrangement radii form at least two concentric annular water jet groups, viewed in the circumferential direction of the fountain core, wherein two adjacent water jets located at the different arrangement radii are arranged in such a way that they are radially offset from each other. By this arrangement of the water jet, the water jet direction and the water jet force of the water pump do not need to be controlled separately and precisely, and the force component in the horizontal direction can occur at any time only by means of the structural arrangement. In the case of uniform water spray, this component is determined by the structure and generally acts in only one direction. For a fountain device which is round as a whole, force components along one direction can cause the fountain device to continuously rotate towards one direction, so that a continuously-changing fountain effect is obtained. In the case of intermittent water spraying, this component is determined by the amount of water sprayed once, the time interval between adjacent two sprays, and the structure. The single water jet quantity can influence the horizontal force component generated in the single water jet, so that when the whole fountain device is sprayed with water for the first time, the force component along one direction can cause the fountain device to continuously rotate towards one direction, and after the water jet for the first time is finished, the fountain device continuously moves under the action of inertia until the kinetic energy is dissipated or the next time is started. For intermittent water spraying at a certain water spraying time interval, the intermittent water spraying period generating unordered movement can be determined, so that the fountain device can generate intermittent random variation fountain effect when intermittent water with a certain period does not need to move.

Preferably, the fountain core further comprises at least one first light, at least part of which protrudes outside the housing, so that the light emitted by the first light is directed at least partially obliquely onto the fountain ejected by the fountain core. Preferably, the radius of the placement of the water jet on the top surface of the fountain core is smaller than the radius of the placement of the first light and the height of the placement of the water jet is greater than the height of the placement of the first light as viewed in the axial direction of the fountain core, such that the first light is able to direct at least a portion of the light obliquely toward the mist or drop-like region of the fountain formed by the water jet. Preferably, the plurality of water jets are distributed on at least two mutually different radii and are arranged on the top surface of the fountain core in such a way as to form at least two concentric annular water jet groups, wherein radially adjacent water jets located on different arrangement radii are arranged in a mutually circumferentially staggered manner. In this way, the invention has at least the advantages of: 1. the water jet is arranged in such a way as to be beneficial to weakening the strength of disordered movement; 2. the water jet is arranged into at least two rings, so that the generated fountain is provided with at least two layers of water drop-shaped areas or fog areas which can generate approximate fan-shaped surfaces with different heights, and particularly, the lamplight or sunlight generated by the first lamp can be obviously diffused in the water drop-shaped areas or the fog areas under the assistance of disordered movement, so that a rainbow with a certain degree can be formed, and the festival atmosphere can be rendered.

Preferably, the fountain core is provided with a reflecting part capable of forming a point light source of the first lamp into a surface light source, so that the light emitted by the first lamp can form a mist area or a water drop area of the fountain with the water spray.

Preferably, at least a portion of the water inlet of the hydro block is extendable beyond the float when the fountain cartridge is mounted in place on the float. With this arrangement, the invention also has the following advantages: when pumping water, the water inlet will generate low pressure area, and the fountain will fluctuate under the action of the upper liquid pressure and the gravity of the fountain.

Preferably, when the fountain device is placed in water, the fountain device can float on the water surface, and in all directions along the water surface, the floating part can provide buoyancy for the fountain core at a position beyond the outer edge of the fountain core.

Preferably, the movement mounting aperture is configured to at least partially match the housing of the fountain movement in the event that the float is filled with a low density fluid, such that when the float is filled with a low density fluid, the float expands to cause at least a portion of its surface at the movement mounting aperture to bear against a wall of the housing of the fountain movement to mount the fountain movement on the float.

Detailed Description

Details are described below in conjunction with FIGS. 1-12.

Example 1

Embodiment 1 discloses a fountain apparatus including a fountain deck 100 and a float 200. Fountain cartridge 100 may be mounted on a float.

Fountain cartridge 100 includes a hydro portion 110 and a power source 120 that provides energy to hydro portion 110. The fountain cartridge 100 absorbs water from a water inlet located at a lower portion through the hydro unit 110 and is ejected through a water jet 1311 located at an upper portion to form a fountain. The hydraulic unit 110 is, for example, various water pumps.

The float 200 allows the fountain device to float in water, which may be a rigid hollow housing or a flexible housing. In the case of a flexible collapsible housing, the float 200 may form a cartridge mounting channel 240 for holding the fountain cartridge 100 in a state of being inflated by injecting a low-density fluid, so that the fountain cartridge 100 can form a fountain through the hydro block 110 in a state in which the fountain device floats in water.

Preferably, the cartridge-mounting aperture 240 is configured to at least partially mate with the housing 130 of the fountain cartridge 100 when the float 200 is filled with a low-density fluid, such that when the float 200 is filled with a low-density fluid, the float 200 expands and at least a portion of its surface at the cartridge-mounting aperture 240 rests on the walls of the housing 130 of the fountain cartridge, mounting the fountain cartridge 100 to the float 200 in such a way that the fountain cartridge 100 is retained by the cartridge-mounting aperture 240. The movement mounting hole 240 may be formed to have a larger end and a smaller middle end. The portion of the housing 130 of the fountain cartridge 100 mounted in the cartridge mounting aperture 240 may also have a shape with two large ends and a small middle adapted to the cartridge mounting aperture 240.

Preferably, the floatation portion 200 may employ an inflatable bladder. Preferably, the floating part 200 may be provided with an air tap for inflating and deflating. When the bladder is inflated, the bladder expands and at least a portion of its surface at cartridge mounting aperture 240 applies a clamping force to housing 130 of fountain cartridge 100. The cartridge mounting channel 240 in the float 200 can retain the fountain cartridge 100 in the float 200 with a low density fluid, yet float the fountain cartridge 100 on the water surface.

Preferably, when the air bag is inflated, the air bag is inflated and at least a portion of its surface at the movement mounting hole 240 may be supported on the wall of the housing 130 of the fountain movement having a large middle size at both ends thereof to mount the fountain movement 100 on the float 200 in such a manner that the fountain movement 100 is held by the air bag. Whereby the gap between the air bag and the fountain cartridge is reduced while the inflated float 200 can hold and stabilize the fountain cartridge 100.

Preferably, the end of the float 200 has an interface for connecting the fountain cartridge 100. This interface is used, for example, to screw fountain cartridge 100 into cartridge mounting aperture 240, see fig. 2, 6, 7, 8, and 9. The interface allows the fountain device to assume a fixed orientation such that its geometric center or center of gravity extends through cartridge mounting aperture 240. Instead of a threaded interface, fountain cartridge 100 may also be attached to float 200 by means of a velcro adhesive.

Preferably, the hydro block 110 delivers water to the water jets 1311 through the water inlet of the hydro block 110 to form a fountain. The fountain assembly has a plurality of water jets 1311 on its top surface that are distributed circumferentially, particularly along at least two circumferential lines. During the water spraying process, the fountain device generates horizontal movement on the water surface due to the reaction force of the fountain. The fountain sprayed by the fountain device falls to the water surface to cause fluctuation, and the fountain device indirectly causes the change of the spraying direction so as to cause the horizontal component of dynamic change; alternatively, the fountain drop ejected by the fountain device impacts the fountain device to directly cause the fountain ejection direction of the fountain device to change, thereby causing a dynamically changing horizontal component.

Preferably, the float bottom can be anchored to the bottom of the pool by a cable connection sinker whereby the fountain device can move circumferentially with the water spray.

Preferably, fountain cartridge 100 also includes a first light 141. The first lamp 141 is installed in the first chamber and extends at least part of the first lamp 141 out of the housing so that light emitted from the first lamp 141 is at least partially inclined toward the fountain ejected from the fountain core.

Preferably, as shown in fig. 4 and 5, the radius of the placement of the water jet 1311 on the top surface of the fountain core 100 is smaller than the radius of the placement of the first lamp 141 and the placement height of the water jet 1311 is greater than the placement height of the first lamp 141 as viewed in the axial direction of the fountain core 100, so that the first lamp 141 can direct at least a portion of the light obliquely toward the mist or drip of the fountain formed by the water jet 1311. The arrangement radius means: the distance from the mounting axis of the first light 141 or the placement axis of the water jet 1311 to the fountain cartridge 100 axis. Alternatively, the placement radius may also refer to the distance of the mounting axis of the first lamp 141 or the placement axis of the water jet 1311 from the axis of the cartridge mounting tunnel 240. Alternatively, the placement radius may also refer to the distance of the mounting axis of the first lamp 141 or the placement axis of the water jet 1311 to the fountain device axis. The installation height refers to the distance from the geometric center of the first lamp 141 to the plane of the water inlet and the distance from the geometric center of the water jet 1311 to the plane of the water inlet after the fountain device is installed. Alternatively, the mounting height may also refer to the distance from the geometric center of the first lamp 141 to the horizontal after the fountain device is formed by mounting, and the geometric center of the water jet 1311 to the horizontal. After the water is sprayed out, the fountain formed by the fountain device has a mist area or a water drop area. This relative positioning of the water jet 1311 and the first lamp 141 causes the light to impinge at least partially obliquely on the mist or drop zone. The light refracts and/or reflects in the fog area or the water drop area so as to render beautiful landscapes and holiday atmosphere.

Preferably, the fountain cartridge 100 is provided with a reflection sheet capable of forming a point light source of the first lamp 141 into a surface light source. By reflection, the light emitted from the first lamp 141 can form a cluster mist with the water jet 1311 in the mist or drop region of the fountain. As shown in fig. 5, the reflective sheet is annularly disposed in the socket of the first lamp 141 or the socket itself has reflective capability, so that the light of the first lamp 141 can be directed to the spray area or the droplet area of the fountain after being reflected to form the surface light source, thereby scattering and illuminating the spray area formed by the above-mentioned geometric arrangement of the water jet 1311.

Preferably, the plurality of water jets 1311 are distributed over at least two mutually different radii and are arranged on the top surface of fountain cartridge 100 in a manner that forms at least two concentric annular sets of water jets, wherein radially adjacent water jets located at different radii are arranged in a circumferentially staggered manner relative to one another. As shown in fig. 5, the fountain cartridge 100 is provided with two concentric ring-shaped water jet groups, and two adjacent water jets in the inner water jet group and the outer water jet group are arranged in a manner of being radially offset from each other. By this arrangement, on the one hand, the fountain can be made to have a multi-layered visual effect and the visual effect created by the fountain is enhanced under co-action with the first lamp 141, and on the other hand, the arrangement can also be made to have a dynamically varying resultant force to create a disordered motion in the horizontal direction on the water surface.

Preferably, the axial length of the cartridge mounting aperture 240 is less than the axial length of the fountain cartridge 100, such that at least a portion of the water inlet of the hydro block 110 extends beyond the float 200 when the fountain cartridge 100 is mounted in place on the float 200. Thus, the fountain cartridge 100 can reliably absorb water in the case where the float is inflated.

Preferably, the fountain device floats to the surface of the water when placed in the water. The float 200 provides buoyancy to the fountain cartridge 100 at a location beyond the outer edge of the fountain cartridge 100 in all directions along the water surface.

After the fountain device is placed in water, the fountain core 100 can float on the water surface along with the floating part 200, and the water inlet of the hydraulic part 110 is positioned below the water surface. When the hydraulic section 110 is powered on 120, the hydraulic section 110 may transfer at least part of the water entering the water inlet of the hydraulic section 110 to a state of ejecting the water surface to form a fountain.

Preferably, fountain cartridge 100 is attachable to a float 200 having different configurations but having an adapter interface that is attachable to fountain cartridge 100 to form a fountain device of different configurations. Preferably, the floating part 200 may be in a flying saucer shape, a lotus leaf shape, or a starfish shape, see fig. 10 or 11. The float 200 may also be shaped as some animal, such as a fish, duck or swan.

Preferably, the float 200 is provided with a receptacle that can be used to mount the fountain cartridge 100. The receiving portion may be provided in such a manner as to penetrate from one side to the other side of the floating portion 200.

For example, fountain cartridge 100 may be provided with a clasp, threads, and/or magnets for removably attaching float 200. A clasp, screw, and/or magnet may also be provided on the float 200 to mate with the fountain cartridge 100.

The invention can at least realize the following beneficial technical effects by adopting the mode: first, the shape of the floating part 200 can be changed to quickly meet the demands of different customers on the shape of the floating part 200, so that the labor intensity of a designer can be reduced, and the research, development and manufacturing costs of a producer can be reduced; second, the customer can use the original fountain movement 100 to be matched with floating parts 200 with different forms purchased in addition to meet the activity atmosphere requirements of different occasions or the festival atmosphere requirements of different festivals, so that the waste of resources can be reduced, and the purchase cost can be reduced for the customer.

Preferably, the float 200 may be made of a material having a fixed shape after being processed only after being inflated, such as at least one of plastic, PVC, and transparent rubber. Preferably, the float 200 may form a swim ring shape after inflation. Preferably, the fountain core 100 may be provided with a concave structure to clamp the fountain core 100 to the inner ring of the swim ring-shaped float 200 through the concave structure after the float 200 is inflated.

Preferably, at least part of the float 200 may be made of transparent glass or frosted glass.

Preferably, the outer surface of the floating part 200 may have light transmittance. Preferably, at least a portion of the light emitted by the light emitting components within fountain cartridge 100 may be directed onto float 200 to illuminate the float. Preferably, at least a portion of the light emitted by the light emitting components within fountain cartridge 100 may be directed onto the fountain. Preferably, at least a portion of the light emitted by the light emitting components within fountain cartridge 100 may be directed into the water. Preferably, the float 200 may emit at least a portion of the light emitted by the light emitting components within the fountain cartridge 100 onto the float 200 to exhibit a lighting effect.

Preferably, the floating part 200 may be in a unitary structure or a separate structure. The integrally constructed float 200 may be blow molded. The floating part 200 of the split structure can be formed by closely connecting an upper part and a lower part.

Preferably, the floating unit 200 may be filled with a portion of the floating aid 210 capable of floating on water, so that the floating unit 200 and/or the fountain core 100 is prevented from sinking into the water by the floating aid 210 when water is introduced into the floating unit 200, see fig. 9. For example, the float 210 may be a floatable hollow sphere to provide buoyancy through the hollow sphere when water is in the float 200 to prevent the float 200 and/or fountain cartridge 100 from sinking into the water. Preferably, the hollow spheres may be transparent plastic spheres and/or frosted plastic spheres. For another example, the floatation aid 210 may be at least one inflatable bag to provide buoyancy by the inflatable bag to prevent the floatation aid 200 and/or fountain cartridge 100 from sinking into the water when water is fed into the floatation aid 200. Preferably, the airbag may be a PO airbag, a PA airbag, and/or a PE airbag. Moreover, the airbag is completely isolated from the outside air and water within the floatation member 200 when the floatation member 200 is not damaged. The airbag ages more slowly than if it were exposed directly. The airbag can function normally at least for a period of time when the float 200 is broken into water.

Preferably, the fountain movement 100 and/or the floater 200 may be provided with a binding 410. The binding-wire portion 410 may be used to bind the limit cord 420.

The length of the spacing rope 420 between the binding-wire portion 410 and the weight 430 may be equal to or greater than the depth of water at which the floating portion 200 or fountain device is located, see fig. 9. Preferably, the binding-wire portion 410 can be used to connect one end of the spacing cord 420. The other end of the stopper rope 420 can bind the weight 430.

Preferably, the fountain core 100 and the floater 200 may be provided in such a manner that they are independently waterproof even when the fountain core 100 and the floater 200 are respectively put into water in a state of being separated from each other.

Preferably, fountain cartridge 100 may be provided with a mounting space that independently provides water resistance for at least a portion of the electrical components disposed within housing 130 and/or on housing 130. The invention can at least realize the following beneficial technical effects by adopting the mode: first, fountain movement 100 does not need to incorporate float 200 to achieve sealing, has the advantage of strong independence and interchangeability; second, the floating part 200 is disposed at the periphery of the fountain core 100, and plays a certain role in protecting the fountain core 100, and even if the floating part 200 is damaged, the liquid entering the floating part 200 cannot flow into the fountain core 100, so that safety problems such as short circuit cannot be caused. Preferably, the electrical component may be at least one of the power source 120, the safety protection device, the hydro part 110, the lamp, and the controller.

Preferably, the housing 130 may comprise a first section 131 and a second section 132, see fig. 2.
