Description

Technical Field

[0001] The invention relates to a water vibration wave generator for generating water vibration waves for massage in a bathtub. Background Art

[0002] Generally speaking, a bathtub is a container used to hold water for bathing. For bathing, you can soak your body in the bathtub, but you can also soak your body according to the water temperature according to warm bath method or cold therapy to improve your health.

[0003] However, the bathtub only performs a simple water-holding function, so the health benefits of the water temperature are limited. Therefore, the "underwater vibration generating device" of Korean Registered Patent Gazette No. 10-1070096 (announced on October 4, 2011) has been launched before.

[0004] In the conventional underwater vibration generating device, the underwater vibration generating device rapidly rotates the vibrating blade equipped on the rotating shaft when immersed in water, and generates flowing water vibration waves caused by pressure changes in the water flowing on the upper surface of the vibrating blade. The flowing water vibration waves can remove waste, decompose fat, reduce depression, relax muscles, etc., thereby improving the massage effect.

[0005] However, the conventional underwater vibration generating device requires a relatively long length in order to generate vibration waves according to the rotation of the vibration blades. Therefore, there is a problem that the rotation radius is large, the volume occupied when installed in the bathtub is large, and a large bathtub is required, thus requiring a large installation space.

[0006] In addition, since the traditional underwater vibration generating device installs the vibrating blades on both sides of the fixed block and fastens them with fixing bolts, there is a problem that when the fixing bolts are loosened, the vibrating blades will separate from the rotating fixed block, causing damage to the body or the bathtub and resulting in a safety accident.

[0007] In addition, traditional underwater vibration generating devices have the problem of low vibration wave generation effect and cannot generate various forms of vibration waves. Therefore, the massage effect of the vibration waves cannot meet the expected problem, because only the water flow resistance generated during rotation can generate vibration on the vibrating blades. Summary of the Invention

[0008] Problems to be solved by the invention

[0009] The present invention is proposed to solve the above-mentioned problem. The subject to be solved by the present invention is to form a turbulence generating part for generating turbulence between the first vibration generating wing and the second vibration generating wing. Even if the length of the first vibration generating wing and the second vibration generating wing is reduced, the vibration effect generated by the turbulence generated by the turbulence generating part can be compensated, thereby reducing the rotation radius of the first vibration generating wing and the second vibration generating wing, thereby minimizing the volume, thereby providing the minimum installation space and the purpose of generating vibration.

[0010] In addition, the purpose of the present invention is to form a warm current generating plate for generating warm current and a diffusion wing for generating warm current on the diffusion warm current generating plate at the place where the warm current is generated. As the warm current diffuses, the area applicable to the warm current on the first vibration generating wing and the second vibration generating wing is expanded, thereby providing a flowing water vibration wave generating device that can improve the vibration generation effect.

[0011] In addition, the purpose of the present invention is to set the first vibration generating wing and the second vibration generating wing installed on the rotating wing unit in a form through which the drive shaft passes, so that even if the first vibration generating wing and the second vibration generating wing are released from fixation, the first vibration generating wing and the second vibration generating wing will be separated by centrifugal force, thereby providing a water vibration wave generating device to prevent safety accidents such as damage to the body or bathtub.

[0012] In addition, the purpose of the present invention is to provide a flowing water vibration wave generating device, which can form the first vibration generating wing and the second vibration generating wing into different sizes or different materials, or form different materials according to the incision or coating texture or part to generate different vibration waves, thereby improving the massage effect of the vibration wave.

[0013] Means used to solve problems

[0014] To achieve the aforementioned problem, according to an embodiment of the present invention, an oil-water vibration wave generating device is coupled to a drive motor and a drive shaft rotated by the drive motor. The oil-water vibration wave generating device includes a blade unit that generates oil-water vibration waves due to fluid resistance. The blade unit vibrates in water in response to the oil-water resistance generated by rotation, thereby generating a first vibration generating blade. The first vibration occurs at the lower portion of the first vibration blade, and a second vibration wave is generated due to the oil-water resistance, thereby generating a second vibration. Furthermore, the device includes a warm flow generating portion located between the first and second vibration generating blades for generating a warm flow. This allows the first and second vibration generating blades to easily vibrate and generate vibration waves, even if their lengths are shortened to minimize their rotational radius.

[0015] The warm flow generating locations may be provided in pairs so that the blade units are point-symmetrical around the rotating drive axis.

[0016] The warm current generating portion is established between the first vibration generating blade and the second vibration generating blade, and may include a warm current generating plate that generates warm current as it rotates, and a diffusion blade composed of the warm current generating plate that pushes the warm current generated by the warm current generating plate toward the outer ends of the first vibration generating blade and the second vibration generating blade.

[0017] The first vibration generating wing and the second vibration generating wing may respectively include connections of the first vibration generating wing and the second vibration generating wing to prevent separation from the drive shaft as the second vibration generating wing is loosened, and the drive shaft passes through and clamps the wing shaft hole.

[0018] The first vibration generating wing and the second vibration generating wing can be formed in different sizes or made of different materials to generate different vibration waves.

[0019] Effects of the Invention

[0020] According to the present invention, a turbulence generating portion for generating turbulence is formed between the first vibration generating wing and the second vibration generating wing. By increasing the vibration of the first vibration generating wing and the second vibration generating wing through the turbulence generated in the turbulence generating portion, the length of the first vibration generating wing and the second vibration generating wing can be made relatively short, thereby reducing the rotation radius, so that the size can be made compact and the installation space can be minimized.

[0021] In addition, the present invention can also form a diffusion wing at the warm current generating location, so that the warm current generated by the warm current generating plate can be diffused through the diffusion wing, thereby expanding the applicable range of the warm current on the first vibration generating wing and the second vibration generating wing and improving the vibration generating effect.

[0022] In addition, the present invention installs the first vibration generating wing and the second vibration generating wing on the drive shaft in the form of a drive shaft through which the drive shaft passes. As the fixation of the first vibration generating wing and the second vibration generating wing is released, it can prevent the occurrence of safety accidents such as damage to the body or bathtub caused by the separation of the first vibration generating wing and the second vibration generating wing due to centrifugal force.

[0023] In addition, the present invention can also form the first vibration generating wing and the second vibration generating wing into different sizes or different materials, or form the cut groove or coating pattern or part into different materials, to generate various forms of vibration waves and improve the vibration wave massage effect.

[0041] 200: Bathtub DETAILED DESCRIPTION

[0042] Hereinafter, please refer to the accompanying drawings to describe embodiments of the present invention.

[0043] like Figures 1 to 2As shown, the water flow vibration wave generating device 100 in the embodiment of the present invention may include a driving motor 120 .

[0044] The driving motor 120 may be implemented as a motor that drives a rotating shaft to rotate. The driving motor 120 may generate vibration waves by rotating the blade unit 150 .

[0045] The driving motor 120 can directly connect the rotating shaft to the driving shaft 130, or use the rotating shaft of the driving motor 120 as the driving shaft 130, or install a reducer between the rotating shaft of the driving motor 120 and the driving shaft 130 so that the driving shaft 130 rotates through the output converted by the reducer.

[0046] The driving motor 120 may be inserted into a motor housing 125 on the main body housing 110 to protect the driving motor 120 from moisture.

[0047] The driving motor 120 can have its rotation speed controlled by a driving controller according to the strength of the water flow or the generated vibration waves.

[0048] The drive controller is used to adjust the rotation speed and is composed of an operating part, such as a button or a groove, through which the rotation speed of the drive motor 120 can be adjusted.

[0049] like Figure 1 and Figure 2 As shown, the water vibration wave generating device 100 in the embodiment of the present invention may include a main body housing 110 .

[0050] The main body housing 110 may guide the diffusion direction of the vibration wave generated by the wing unit 150 so as to generate the vibration wave generated by the flowing water.

[0051] The main housing 110 may be formed in a quadrangular box shape, and the driving motor 120 may be fixedly mounted on the upper portion of the main housing 110 .

[0052] Furthermore, a motor housing 125 may be installed on the upper portion of the main housing 110 to enclose the driving motor 120 .

[0053] Openings 111 and 113 are formed through the front and back of the main housing 110 , and vibration waves generated by the wing unit 150 may be diffused through the openings 111 and 113 , and the main housing 110 is circulated by the wing unit 150 through the water in the bathtub 200 through the openings 111 and 113 .

[0054] In order to prevent safety accidents in which the body is injured by the rotating wing unit 150 , an anti-entry belt 115 may be provided on the openings 111 , 113 adjacent to the body on the main body housing 110 to prevent the body from entering the openings 111 , 113 .

[0055] The shockproof belt 115 may be provided with a plurality of openings 111, 113 in the form of a rod or formed in the form of a net, but in the form of a net, the vibration wave generated by the wing unit 150 may be weakened by the net, so it is better to be formed in the form of a rod.

[0056] Moreover, on both sides of the seal of the main body housing 110 , a bracket (not shown) placed on the bathtub 200 through the main body housing 110 can be formed on the top of the bathtub 200 so that the wing unit 150 can be located in the water of the bathtub 200 .

[0057] Of course, in the embodiment, it is explained as including the main body shell 110, but if there is no main body shell 110, it may only be composed of the anti-theft belt 115, and the main body shell 110 is not installed. Then, there can be various forms of bracket structures to replace the main body shell 110 and be placed in the bathtub 200.

[0058] like Figures 2 to 6 As shown, according to an embodiment of the present invention, the oil-water vibration wave generating device 100 may include a wing unit 150 .

[0059] The wing unit 150 is located in the water of the bathtub 200 and can generate vibration waves for massage by driving the motor 120 to rotate.

[0060] The wing unit 150 vibrates due to the resistance of oil and water when rotating, and generates vibration waves.

[0061] The wing unit 150 may be mounted on the drive shaft 130 in a plurality of movable positions along the length of the drive shaft 130 .

[0062] The wing unit 150 may include a first vibration-generating wing 151 and a second vibration-generating wing 152 .

[0063] Now, when the first vibration generating wing 151 and the second vibration generating wing 152 rotate, flutter is generated due to fluid resistance, and vibration waves may be generated.

[0064] The first vibration generating wing 151 and the second vibration generating wing 152 may be formed in the form of a right-angled plate, and the first vibration generating wing 151 and the second vibration generating wing 152 may be spaced apart and arranged vertically at a preset interval.

[0065] At the center of the first vibration generating blade 151 and the second vibration generating blade 152 , blade shaft holes 151 a and 152 a through which the driving shaft 130 passes may be formed, respectively.

[0066] Among them, the first vibration generating wing 151 and the second vibration generating wing 152 are clamped by the driving shaft 130. Even if they are separated from each other, they can be dispersed in the circumferential direction by centrifugal force to prevent damage to the body.

[0067] The first vibration generating wing 151 and the second vibration generating wing 152 may be arranged at the same angle without conflict with each other with the driving shaft 130 as the center.

[0068] The first vibration-generating wing 151 and the second vibration-generating wing 152 may be formed in different sizes or made of different materials to generate different vibration waves.

[0069] like Figure 5 As shown, the second vibration generating blade 152 and the second vibration generating blade 152 can be formed with cutout grooves 151-1, 152-1, coating patterns 151-2, 152-2 respectively thereon or formed of different materials 151-3, 152-3, so as to facilitate vibration through water resistance.

[0070] For example, Figure 5 As shown in (a), the first vibration-generating wing 151 and the second vibration-generating wing 152 may form cutouts 151-1, 151, so that the ends of the first vibration-generating wing 151 and the second vibration-generating wing 152 can be resisted by the flowing water and vibrate conveniently.

[0071] For example, Figure 5 As shown in (b), when the first vibration generating blade 151 and the second vibration generating blade 152 rotate, in order to make the first vibration generating blade 151 and the second vibration generating blade 152 easily vibrate under different surface tensions, a material with different surface tensions can be formed with the first vibration generating blade 151 and the second vibration generating blade 152 to form a pre-set texture to form the second vibration generating blade 151-2 and the second vibration generating blade 151-2.

[0072] Another example, such as Figure 5 As shown in (c), a portion of the first vibration-generating wing 151 and the second vibration-generating wing 152 can be composed of different materials 151-3 and 152-3, and generate different vibrations according to different rigidities and oil-water resistances.

[0073] At this time, the first vibration generating wing 151 and the second vibration generating wing 152 form a part opposite to the rotation direction with weaker rigidity than the part in the subsequent position, thereby minimizing the deformation of the first vibration generating wing 151 and the second vibration generating wing 152 caused by oil and water resistance during rotation.

[0074] like Figure 4 and Figure 6 As shown, the wing unit 150 may include a wing attachment area 153 .

[0075] The wing fixing area 153 fixes the first vibration generating wing 151 and the second vibration generating wing 152 in an upper and lower separated state, and at the same time can fix the first vibration generating wing 151 and the second vibration generating wing 152 on the driving shaft 130.

[0076] The wing fixing area 153 may be formed in the form of a cylinder, and a diameter of the wing fixing area 153 may be formed smaller than widths of the first vibration generating wing 151 and the second vibration generating wing 152 .

[0077] The first vibration generating wing 151 is placed on the upper part of the wing fixing area 153, and the second vibration generating wing 152 can be placed on the lower part of the wing fixing area 153. A fixing hole 153 is formed on the wing fixing area 153 by forming an axial hole 152a corresponding to the wings 151a and 152a in a state overlapping with the first vibration generating wing 151 and the second vibration generating wing 152.

[0078] Moreover, on the wing fixing area 153, the first vibration generating wing 151 and the second vibration generating wing 152 can be connected and fixed by fixing bolts.

[0079] At this time, the first vibration generating blade 151 and the second vibration generating blade 152 are fixed to the blade fixing area 153 by fixing bolts, so when the first vibration generating blade 151 and the second vibration generating blade 152 are damaged, they can be removed and replaced from the blade fixing area 153.

[0080] On the side of the wing fixing ball 153 , a pressing bolt ball 153 b may be formed to penetrate the fixing structure ball 153 a in order to connect the pressing bolt 153 c penetrating the side of the wing fixing ball 153 to the driving shaft 130 .

[0081] like Figure 3 、 Figure 4 and Figure 6 As shown, wing unit 150 may include a warm air flow generating area 155 .

[0082] The warm flow generating portion 155 may generate warm water to facilitate the vibration of the first vibration generating blade 151 and the second vibration generating blade 152 .

[0083] The warm current generating portion 155 is provided between the first vibration generating blade 151 and the second vibration generating blade 152 , and can generate a warm current between the first vibration generating blade 151 and the second vibration generating blade 152 .

[0084] The turbulence generating part 155 may generate turbulence according to the rotor unit 150 , and may be provided between a pair of first and second vibration generating wings 151 and 152 that are symmetrical with respect to the driving shaft 130 .

[0085] The warm current generating portion 155 generates a warm current, forcing the first vibration generating blade 151 and the second vibration generating blade 152 to vibrate through the warm current to generate vibration waves. Even if the length of the first vibration generating blade 151 and the second vibration generating blade 152 is relatively shorter than before, the warm current can make the first vibration generating blade 151 and the second vibration generating blade 152 vibrate more easily, thereby generating vibration waves.

[0086] Among them, the warm current generating part 155 can reduce the length of the first vibration generating wing 151 and the second vibration generating wing 152, thereby reducing the length of the first vibration generating wing 151 and the second vibration generating wing 152, thereby reducing the radius of the first vibration generating wing 151 and the second vibration generating wing 152, so as to minimize its volume in the bathtub 200.

[0087] The first vibration generating wing 151 and the second vibration generating wing 152 may be formed of a synthetic resin so as to vibrate relatively easily on the wing unit 150 , or be formed in the form of a thin plate having a relatively thin thickness.

[0088] At this time, the thickness of the first vibration generating wing 151 and the second vibration generating wing 152 not only has thickness, but also can prevent the wing unit 150 from being permanently bent due to resistance of flowing water when rotating.

[0089] The warm flow generating portion 155 may include a warm flow generating plate 156 and a diffusion wing 157 .

[0090] The warm current generating plate 156 is installed between the first vibration generating wing 151 and the second vibration generating wing 152 in the form of vertically connecting the first vibration generating wing 151 and the second vibration generating wing 152. The warm current generating plate 156 generates irregular warm current when the blade unit 150 rotates.

[0091] At the top and bottom of the warm current generating plate 156, the flanges supported on the first vibration generating wing 151 and the second vibration generating wing 152 can be bent respectively, and the warm current generating plate 156 can be combined together by connecting parts such as bolts or rivets when the top and bottom flanges overlap with the first vibration generating wing 151 and the second vibration generating wing 152 respectively.

[0092] The diffusion wing 157 is installed on the outside of the warm current generating plate 156 in the opposite direction to the direction of the driving shaft 130, so as to diffuse the warm current generated by the warm current generating plate 156 to the outside of the first vibration generating wing 151 and the second vibration generating wing 152.

[0093] The diffusion wing 157 diffuses the warm current generated by the warm current generating plate 156 to the outside of the first vibration generating wing 151 and the second vibration generating wing 152, thereby expanding the range of the warm current received by the first vibration generating wing 151 and the second vibration generating wing 152, further improving the vibration generation performance, and at the same time, can improve the vibration effect of the entire bathtub by massaging the vibration generated by the first vibration generating wing 151 and the second vibration generating wing 151.

[0094] When viewed from a plane, the diffusion wing 157 moves in the opposite direction of rotation, and the diffusion wing 157 is gradually tilted away from the warm current generating plate 156 to be installed at a preset angle to the warm current generating plate 156 .

[0095] The diffusion wings 157 and the warm current generating plate 156 can be formed of a metal with a relatively higher strength than the first vibration generating wings 151 and the second vibration generating wings 152 to relatively increase the resistance of oil and water and improve the generation and diffusion of warm current.

[0096] The warm current generating parts 155 are a pair of symmetrically installed with the driving shaft 130 as the center. Therefore, the diffusion wings 157 located on both sides with the driving shaft 130 as the center can also be installed on the outside of the warm current generating plates 156 on both sides in a symmetrical manner.

[0097] The diffuser wing 157 may be coupled to the turbulence generating plate 156 by fasteners such as bolts or rivets.

[0098] The following describes the interactions and effects between the components.

[0099] According to an embodiment of the present invention, the oil-water vibration wave generating device 100 installs the driving motor 120 on the upper part of the main body housing 110. The driving motor 120 is installed wrapped by the motor housing 125 to protect the driving motor 120 from moisture.

[0100] A drive shaft 130 rotated by a drive motor 120 extends upright and protrudes through the interior of the main housing 110. Openings 111 and 113 are formed on the main housing 110 to circulate water in the bathtub 200. Anti-entry belts 115 are provided on the openings 111 and 113 where the body is located in the bathtub 200 to prevent the rotating blade unit 150 from causing damage to the body.

[0101] The driving shaft 130 is provided with a blade unit 150 to generate vibration waves generated by flowing water and perform massage through the vibration waves. The blade unit 150 may be provided in plurality and movably along the length direction of the driving shaft 130 .

[0102] The wing unit 150 includes a first vibration-generating wing 151 and a second vibration-generating wing 152 formed in the form of a plate that moves up and down. The first vibration-generating wing 151 and the second vibration-generating wing 152 are provided with a wing fixing port 153 for fixing to the driving shaft 130 .

[0103] The wing fixing opening 153 and the first vibration generating wing 151 and the second vibration generating wing 152 are connected and fixed to each other by fixing bolts.

[0104] On the wing 151 where the first vibration occurs and the wing 152 where the second vibration occurs, wing shaft holes 151a and 152a through which the drive shaft 130 passes are formed, and fixed construction holes 153a are formed through the wing fixing area 153 corresponding to the wing shaft holes 151a and 152a.

[0105] Among them, the first vibration generating wing 151 and the second vibration generating wing 152 are installed in the form of being clamped by the wing shaft holes 151a and 152a passing through the drive shaft 130. Therefore, according to the loosening of the fixing bolts of the first vibration generating wing 151 and the second vibration generating wing 152 on the wing fixing port 153, the separation of the first vibration generating wing 151 and the second vibration generating wing 152 may cause physical injury or cause vibration of the bathtub.

[0106] In the wing fixing ball 153 , a pressurizing bolt ball 153 b connected with a pressurizing bolt 153 c for pressurizing and fixing the wing unit 150 to the drive shaft 130 is connected to the fixing construction ball 153 a .

[0107] In addition, the wing unit 150 will form a pair of turbulence generating parts 155 that are symmetrical with respect to the driving shaft 130 as the center point, so as to reduce the rotation radius of the first vibration generating wing 151 and the second vibration generating wing 152 and minimize the volume.

[0108] The warm current generating part 155 is located between the first vibration generating wing 151 and the second vibration generating wing 152. The warm current generating part 155 is in the form of connecting the first vibration generating wing 151 and the second vibration generating wing 152 up and down, and a warm current generating plate 156 that generates warm current during rotation is provided, and a wing 157 that diffuses and generates warm current is provided on the outside of the warm current generating plate 156.

[0109] According to the embodiment of the present invention, the water vibration wave generating device 100 in the embodiment of the present invention is as follows: Figure 7 As shown, it is installed in the bathtub 200 and is located inside the bathtub 200 of the wing unit 150.

[0110] The bathtub 200 may provide hot water at a temperature of approximately 38° to 50° to enhance the massage effect of the shock waves.

[0111] When the bathtub 200 is installed, the driving motor 120 is activated by the driving controller, the driving motor 120 rotates, the driving shaft 130 rotates, and the blade unit 150 coupled to the driving shaft 130 rotates.

[0112] At this time, the speed at which the wing unit 150 rotates depends on the size, but may be between (400 ~ 1000 rpm).

[0113] When the wing unit 150 rotates, the first vibration-generating wing 151 and the second vibration-generating wing 152 vibrate due to the resistance between oil and water, and the oil and water vibrate due to the vibration, generating vibration waves.

[0114] At this time, since the turbulence generating part 155 is located between the first vibration generating wing 151 and the second vibration generating wing 152, the water flow resistance caused by the turbulence generated in the turbulence generating part 155 and the vibrations generated by the first vibration generating wing 151 and the second vibration generating wing 152 caused by the turbulence increase. Relatively speaking, the length of the wings 152 of the first vibration generating wing 151 and the second vibration generating wing 151 can be reduced, thereby reducing the radius of the wings and thus reducing the volume of the wings.

[0115] The warm current generating portion 155 generates the warm current through the warm current generating plate 156, which diffuses to the surrounding of the wing unit 150 of the diffusion wing 157, and can provide an overall warm current for the first vibration generating wing 151 and the second vibration generating wing 152, thereby increasing the amount of vibration generated by the warm current in the first vibration generating wing 151 and the second vibration generating wing 152.

[0116] In this way, the vibration waves generated by the wing unit 150 spread widely in the bathtub 200, providing the user of the bathtub 200 with low-frequency vibration waves of about 40Hz to 60Hz, which can massage the body, help eliminate waste, reduce fat, relax muscles and reduce depression, etc.

[0117] Therefore, according to an embodiment of the present invention, the oil-water vibration wave generating device 100 forms a turbulence generating part 155 for generating turbulence between the first vibration generating blade 151 and the second vibration generating blade 152. Even if the length of the first vibration generating blade 151 and the second vibration generating blade 152 is reduced in the turbulent flow, the vibration wave generation performance can be improved by the turbulence, so the wing size of the first vibration generating blade 151 and the second vibration generating blade 152 can be minimized.

[0118] In addition, a diffusion wing 157 is formed at the warm current generating area 155. The diffusion wing 157 diffuses the warm current generated at the warm current generating area 155, thereby improving the vibration performance of the first vibration generating wing 151 and the second vibration generating wing 152 caused by the warm current.

[0119] In addition, the first vibration generating blade 151 and the second vibration generating blade 152 are installed in the form of a penetrating drive shaft 130, and the fixing bolts fixing the first vibration generating blade 151 and the second vibration generating blade 152 are loosened, which can prevent the first vibration generating blade 151 and the second vibration generating blade 152 from detaching and causing damage to the body and the bathtub 200.

[0120] In addition, by forming the first vibration generating wing 151 and the second vibration generating wing 152 into different sizes, different materials, cutout grooves 151-1, 152-1 or coating patterns 151-2, 152-2 or partially forming different materials 151-3, 152-3, various forms of vibration waves can be generated to improve the massage effect brought by the vibration waves.

[0121] The above describes the embodiments of the present invention, but the scope of the present invention is not limited thereto, and includes all changes and modifications in the embodiments of the present invention that are easily changed by a person with ordinary knowledge in the technical field to which the present invention belongs and are recognized as equivalent.
