Hereinafter, a fluid pulsation generating device equipped with a control device according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 4.

Figure 1 is an exploded perspective view showing a fluid pulsation generating device equipped with a control device of the present invention according to an embodiment, Figure 2 is a longitudinal cross-sectional view of the main part of Figure 1, and Figure 3 is a fluid flow inside the device of Figure 1. It is a top view showing a rotating body rotating according to, and Figure 4 is a cross-sectional view showing the configuration of the control device assembly according to an embodiment of Figure 1, (a) is a state in which pulsation is generated by the rotation of the rotating cover is unblocked, (b) is a state in which the generation of pulsation is blocked by blocking the rotation of the rotating cover.

As shown in FIGS. 1 to 4, the fluid pulsation generating device 100 equipped with a control device according to the present invention is first formed to protrude from the center, has a hollow interior, and has at least one fluid outlet 112 on the side. 1) A rotating central pipe 112 is formed, and a lower body 110 that receives fluid from the rotating central pipe 112 is provided. At this time, the attached FIGS. 1 to 5 illustrate a case where the lower body 110 is a shower head of a shower.

In addition, the rotating body 120 is inserted into the center of the rotating central pipe 112 at the upper part of the lower body 110 and rotates with respect to the rotating central pipe 112 by the pressure of the fluid flowing out from the fluid outlet 112-1. ) is provided.

In addition, a rotating cover 130 is coupled to the upper part of the rotating body 120 and includes a resistance wing 132 for controlling the rotating speed of the rotating body 120.

In addition, a control device assembly is provided on one side of the rotary cover 130 and selectively blocks the occurrence of pulsation due to rotation of the rotary cover 130 by a user's manipulation.

Specifically, the control device assembly according to one embodiment includes an operation lever 160A provided on one side of the lower body 110; A rotating shaft member 170, one end of which is axially coupled to the operating lever 160A and rotated toward or away from the rotating cover 130 as the user operates the operating lever 160A; It is formed on the opposite end of the rotating shaft 171 of the rotating shaft member 170, and when the rotating shaft member 170 is rotated toward the rotating cover 130, the stopper protrusion 135 formed on the edge of the rotating cover 130 It consists of a latch 175 that blocks the rotation of the rotating cover 130 while being caught.

The operation lever 160A has a button portion exposed to the outside so that the user can press and operate it from the outside through the lever assembly hole 112-3 formed on one side of the lower body (left side in FIG. 1).

In addition, a lower plate 111 is formed integrally with the lower inlet side of the rotation center tube 112, and the lower plate 111 is configured to be separable from the lower body 110. When the lower plate 111 is inserted and assembled into the lower body 110, the space within the lower body 110 is divided into two, up and down. Accordingly, the fluid flowing into one side of the lower body 110 (for example, the right side of FIG. 1) is blocked by the lower plate 111 and is induced to flow into the internal hollow (EM) of the rotating center tube 112.

In addition, a plurality of fitting grooves 121 are formed on the upper part of the rotating body 120, and a fitting protrusion 131 is formed on the lower part of the rotating cover 130 opposite to the fitting groove 121. Accordingly, the fitting groove 121 of the rotating body 120 and the fitting protrusion 131 of the rotating cover 130 are coupled around the fluid outlet 112-1 of the rotating central pipe 112. (see Figure 2)

In addition, the fluid pulsation generating device 100 equipped with the control device according to the present invention is formed around the central hole 122 of the rotating body 120 or the rotating central pipe 112 to ensure the continuous flow of fluid. It further includes a fluid flow microgroove (140, see FIGS. 1 and 3).

Here, the lower body 110 constitutes the lower part of the fluid pulsation generating device 100, and the shape of the lowermost end may be formed differently depending on the object to which it is applied. For example, the lower body 110 is formed at the lower end to correspond to the size of the nozzle or pipe that supplies fluid from the applied shower, water pick (oral care product), massager, etc., and the shape of the coupling portion, so that it is connected to the applied object. Easy combination can be performed.

That is, the lower body 110 receives fluid from the outside through the internal hollow (EM) of the rotating central pipe 112 protruding from the center, and the fluid outlet 112- formed on the side of the rotating central pipe 112. The fluid supplied to the internal cavity (EM) can be discharged through 1). The lower body 110 has an internal space where the rotating body 120 inserted into the rotating center pipe 112 can rotate clockwise or counterclockwise by the pressure of the fluid flowing out from the fluid outlet 112-1. is formed

Looking in detail at each configuration of the lower body 110, the rotating central pipe 112 protrudes from the center of the lower body 110 at a certain length so that the fluid supplied through the internal hollow (EM) flows into the lower body 110. It is supplied only to the center, and the central hole 122 of the rotating body 120 is inserted to serve as a rotation axis that allows the rotating body 120 to rotate according to the flowing pressure of the fluid.

In addition, according to one embodiment, the rotation center pipe 112 has a distribution coupling groove 112-2 formed along the upper side circumference, so that the pressure distribution member 150 can be fitted at the top of the rotation cover 130. . The pressure distribution member 150 is a member that prevents the rotating body 120 and the rotating cover 130 from being separated from the rotating central pipe 112. A detailed description of the pressure distribution member 150 will be described below. .

At this time, the fluid outlets 112-1 may be formed to face each other or be spaced apart at regular intervals on the side of the rotating center pipe 112, and may discharge the fluid supplied along the internal hollow (EM) to the outside. .

When the rotating body 120 is inserted into the rotating central pipe 112, the opening and closing of the fluid outlet 112-1 is determined by the central hole 122 and the fluid guide groove 124 of the rotating body 120. , the rotating body 120 rotates according to the fluid flowing out and can be opened and closed by the central hole 122 and the fluid guide groove 124. That is, when the fluid outlet 112-1 is disposed to face the central hole 122 according to the rotation of the rotating body 120, it is closed by the inner surface of the central hole 122 and is positioned to face the fluid guide groove 124. When placed, it can be opened by the space of the fluid guide groove 124.

In addition, when the fluid outlet 112-1 is closed by the inner surface of the central hole 122, fluid can continue to flow out by the fluid flow microgroove 140 formed along the inner circumference of the central hole 122. And, as a result, continuous rotational force can be provided to the rotating body 120. At this time, there is a difference in the amount of fluid flowing out depending on the opening and closing of the fluid outlet 112-1, and the amount of fluid flowing out into the fluid flow fine groove 140 when the central hole 122 is closed is the fluid guide groove 124. Less fluid may flow out than the amount that would flow out when opened.

That is, the rotating body 120 is inserted into the center of the rotating central pipe 112 at the upper part of the lower body 110, and is activated by the pressure of the fluid flowing out from the fluid outlet 112-1 of the lower body 110. It rotates based on the rotation center pipe (112).

In addition, the rotating body 120 has a circular central hole 122 formed at the center to be accommodated in the rotating center pipe 112, and a fluid guide groove 124 is formed in a spiral direction based on the central hole 122. You can.

Accordingly, as described above, the central hole 122 opens and closes the fluid outlet 112-1 by the rotation of the rotating body 120 to generate a reactive pressure of the fluid, and the pressure causes the rotating body 120 to Pulsations can be created by generating continuous rotational force. Here, pulsation refers to a phenomenon in which the pressure changes periodically while the fluid flows out according to the opening and closing of the fluid outlet 112-1, flowing like a pulse, not only in the shower exemplified in the present invention, but also in massage devices, bidets, etc. It can be usefully applied to various devices.

In addition, a fluid flow micro-groove 140 is formed along the inner circumference of the central hole 122, so that even if the fluid outlet 112-1 is closed, the fluid outlet 112-1 is formed along the fluid flow micro-groove 140. ) to allow fluid to flow out. Accordingly, the fluid continues to flow out without interruption, creating pulsation.

Meanwhile, the fluid guide groove 124 is formed in a spiral direction based on the central hole 122 of the rotating body 120 and guides the flow of fluid flowing out of the fluid outlet 112-1. The central hole ( 122), at least two or more can be formed. The fluid guide groove 124 allows fluid to flow from the central hole 124 to the space between the lower body 110 and the rotating body 120, and allows the rotating body to rotate clockwise or counterclockwise by this flow. can do.

That is, the central hole 122 and the fluid guide groove 124 guide the flow of fluid flowing out of the fluid outlet 112-1 to generate a reactive pressure of the fluid, and a separate power device is added due to this pressure. Pulsation of the fluid can be generated by providing rotational force to the rotating body 120 without any need.

Looking at the central hole 122 and the fluid guide groove 124 in detail with reference to FIG. 3, FIG. 3(a) shows the fluid flowing out from the fluid outlet 112-1 when the fluid outlet 112-1 is opened. This is a diagram illustrating the direction (WH) flowing along the fluid guide groove 124. The rotating body 120 rotates according to the flow of the fluid, thereby generating fluid pulsation.

Meanwhile, Figure 3(b) shows the direction in which the fluid outlet 112-1 is closed as the rotating body 120 rotates, and the fluid flowing out of the fluid outlet 112-1 flows along the fluid flow microgroove 140. This is a diagram explaining (WH), and the rotating body 120 rotates according to the flow of the fluid, thereby generating pulsation of the fluid. In FIG. 3, the rotating body 120 rotates counterclockwise as the fluid outlet 112-1 is repeatedly opened and closed, and the amount of fluid flowing out in FIG. 3A is shown to be greater than in FIG. 3B (arrow thickness). .

The rotating cover 130 is coupled to the upper part of the rotating body 120 through a fastening means (not shown) and can rotate together with the rotating body 120. The rotating cover 130 may have a hole formed in the center to correspond to the central hole 122 of the rotating body 120, and a plurality of resistance wings 132 may be disposed on the upper surface based on the central hole.

For example, the plurality of resistance wings 132 may be arranged at regular intervals, and fastening means (not shown) may be implemented as screws. In addition, as long as the rotating body 120 and the rotating cover 130 can be connected, adhesives, mechanical assembly methods, etc. can be applied, and the rotating body 120 and the rotating cover 130 can be formed as one piece.

The resistance wing 132 is formed as a partition and can block some of the fluid flowing near the rotating cover 130 when the rotating body 120 rotates, thereby controlling the flow of fluid to adjust the rotational speed of the rotating body 120. there is.

On the other hand, the resistance wing 132 may not be formed on the rotating body 120 as needed, and this is an implementation problem in applying the fluid pulsation generator 100 equipped with the present invention control device, so the resistance wing 132 may not be formed on the rotating body 120 as needed. The presence or absence of wings 132 may be determined as needed.

The fluid flow microgroove 140 is formed along the upper inner circumference of the central hole 122 of the rotating body 120 to provide continuous flow of fluid when the fluid outlet 112-1 is closed. The fluid flow microgroove 140 prevents the fluid outlet 112-1 from being completely closed by the central hole 122 so that the fluid continues to flow out from the fluid outlet 112-1, and thus the rotating body 120 It can be rotated without stopping.

The pressure dispersion member 150 is connected to the distribution coupling groove 112-2 of the rotation center pipe 112 after the rotation body 120 and the rotation cover 130 are inserted into the rotation center pipe 112 of the lower body 110. It can be accommodated so that the rotating body 120 and the rotating cover 130 do not separate from the rotating central pipe 112 when rotating. For example, the pressure distribution member 150 may be implemented as a plastic washer or a metal washer.

Meanwhile, the shape and configuration of the pressure dispersion member 150 and the distribution coupling groove 112-2 are not intended to be limited as described above, and the rotating body 120 and the rotating cover 130 are connected to the rotating central pipe 112. ) Any shape can be implemented as long as it does not deviate from the structure.

Hereinafter, the configuration and operational relationship of the control device assembly according to an embodiment of the present invention will be examined with reference to FIG. 4.

First, Figure 4(a) shows that when the user presses the operation lever 160A provided on one side of the lower body 110, the rotation axis member 170 coupled to the operation lever 160A is rotated ( 171) is rotated in a direction away from the rotating cover 130. In this state, the latch 175 of the rotating shaft member 170 is also spaced apart from the rotating cover 130, so the rotation of the rotating cover 130 is unblocked. In this state, as the fluid flows into the internal hollow (EM) of the rotation center pipe 112, the fluid is discharged from the fluid outlet (112-1) of the rotation center pipe 112, causing the rotation cover 130 to rotate and pulsate. occurs. Accordingly, the user can perform a massage or pulsation cleaning function by pulsation without the need to add a separate power device through the present invention applied to a shower, etc. in the state (pulsation mode) of FIG. 4(a).

Meanwhile, Figure 4(b) shows that as the user presses the operation lever 160A provided on one side of the lower body 110 again, this time the rotation axis member 170 axially coupled to the operation lever 160A It is rotated around the rotation axis 171 in a direction closer to the rotation cover 130. In this state, the latch 175 of the rotating shaft member 170 is also rotated toward the rotating cover 130, and the stopper projection 135 of the rotating cover 130 is caught by the latch 175, so that the rotating cover 130 rotation is blocked. In this state, even if fluid flows into the internal hollow (EM) of the rotating center pipe 112, the rotating cover 130 is caught by the latch 175 and cannot rotate, so no pulsation is generated. Accordingly, the user can use products such as a general shower head from which pulsation has been removed in the state (non-pulsation mode) shown in FIG. 4(b).

Figure 5 is an exploded perspective view showing a fluid pulsation generating device equipped with the control device of the present invention according to another embodiment, Figure 6 is a longitudinal cross-sectional view of the main part of Figure 5, and Figure 7 is a control device according to another embodiment of Figure 5. A cross-sectional view showing the device assembly configuration, (a) is a state in which pulsation is generated as the rotating cover is rotated due to the inflow of fluid as the first communication hole is opened, and (b) is a state in which the rotating cover is not rotated as the first communication hole is closed. This is a state in which no pulsation occurs.

Hereinafter, with reference to FIGS. 5 to 7, the configuration and operational relationship of a fluid pulsation generating device equipped with a control device according to another embodiment of the present invention will be examined.

Since most of the configurations of the fluid pulsation generating device with the control device of the present invention according to the other embodiment are the same as those in the above-described embodiment, the description will focus on the control device assembly with a different configuration.

The control device assembly of the present invention according to another embodiment includes an operation lever (160B) provided on one side of the lower body (110); The first communication hole 180-1 is connected to the lower inlet side of the rotation center pipe 112 and communicates with the rotation center pipe 112, and the lower body 110 avoids the rotation center pipe 112. Bypass members 180 each having a second communication hole 180-2 directly communicating therewith; And one end is axially coupled to the operation lever (160B) to selectively block the first communication hole (180-1) or the second communication hole (180-2) as the user operates the operation lever (160B). It may be composed of a valve member 190.

In addition, one end of the valve member 190 constitutes a rotation axis 192, and the other end of the valve member 190 is provided with a ball seat 193 (see FIGS. 5 and 6) and the ball seat 193. A spring 194 (see FIG. 6) that adds elasticity is further provided so that the ball seat 193 elastically contacts the first communication hole 180-1 or the second communication hole 180-2.

Hereinafter, with reference to FIG. 7, the operational relationship of the control device assembly according to another embodiment is as follows.

First, in Figure 7(a), as the user holds the operation lever 160B with his hand and rotates it counterclockwise, the valve member 190 is also rotated in the same direction. Accordingly, as shown in FIG. 7(a), the first communication hole 180-1 of the bypass member 180 is opened as the valve member 190 rotates, while the second communication hole 180- 2) is closed by the valve member 190. At this time, as fluid flows into the open first communication hole 180-1 and the rotating central pipe 112, the cover rotates due to the fluid discharged through the fluid outlet 112-1 of the rotating central pipe 112. As (130) rotates, pulsation is generated. (pulsation mode)

Meanwhile, in Figure 7(b), as the user rotates the operation lever 160B counterclockwise, the valve member 190 is also rotated in the same direction. Accordingly, as shown in FIG. 7(b), the first communication hole 180-1 of the bypass member 180 is closed by the valve member 190, while the second communication hole 180-2 is closed. It is open. At this time, fluid flows into the open second communication hole 180-2 and the inner space (not shown) of the lower body 110. In this case, the fluid is rotated at the center of rotation as shown in FIG. 7(a). Since it is prevented from flowing into the pipe 112, the rotating cover 130 cannot be rotated and ultimately no pulsation is generated. (Non-pulsating mode = normal mode)

Therefore, when the fluid pulsation generating device 100 equipped with the control device according to the present invention is applied to the shower head of a shower, the user simply manually operates the

operating levers

160A and 160B provided on one side of the lower body. A pulsation mode can be executed in which the rotating body 120 is rotated using only the hydraulic pressure of the fluid to discharge a pulsating water stream. Meanwhile, when the user wants to turn off the pulsation mode, the operation levers 160A and 160B can be manually operated in the opposite direction again to switch to a non-pulsation mode (normal mode) that does not generate pulsation.

For example, when the pulsating water flow generated in the pulsation mode is directly connected to the shower as described above, a pounding water stream is realized, enabling massage and achieving the effect of excellent cleaning power. Meanwhile, the nozzle of the Waterpick, an oral care product, If you just connect it, you can easily create a pulsating water current that can massage the gums, giving you the advantage of adding massage and cleaning functions to products in various fields.

In addition, the present invention is not limited to just one embodiment described above, and the same effect can be created even when changing the detailed configuration, number, and arrangement structure of the device, so those skilled in the art will understand the present invention. It is stated that addition, deletion, and modification of various configurations are possible within the scope of the technical idea.

The present invention can be widely used in the field of fluid pulsation generating devices.
