[Patent Document 2] Japanese Patent No. 2011-115771

Patent Document 1 describes a shower head that can adjust the flow rate when it is sprayed with fine bubble water. However, the shower head is passed through a fine bubble generating device to generate fine bubble water containing fine bubbles. The overall construction is bulky.

Further, the shower head system described in Patent Document 2 has a relatively simple structure by increasing the speed inside the tube to cause fine bubbles in the water. However, in order to generate fine bubbles, it is necessary to reduce the diameter of the tube to increase the speed inside the tube. As a result, it is difficult to increase the amount of water discharged, and it is difficult to adjust the amount of water.

The present invention is directed to improvements in the problems that have existed in the prior art. The purpose is to allow the shower head to generate large amounts of water while generating tiny bubbles through a simple structure.

In order to achieve the above object, a feature of the present invention includes a main body forming a liquid inflow port: a microbubble hole provided in the inside of the main body to allow a liquid to pass through the inflow port to form microbubbles; and microbubbles generated in the macropore a portion located in front of the microbubble hole; and a water outlet portion having a water outlet for spraying the liquid passing through the microbubble generating portion.

Therefore, the simple structure of the microbubble which generates the microbubbles and the large water inlet of the large holes allows the generation of the microbubbles and the larger the amount of water discharged than the conventional techniques.

According to the above configuration, it is also possible to provide a switch member, a water inlet for plugging the microbubble generating portion, and an adjustment member to adjust the amount of the water outlet of the switch member to adjust the flow of the microbubble. The amount of water in the department. Therefore, by adjusting the amount of the water outlet of the switch component, the amount of water discharged from the shower head can be adjusted.

Based on the foregoing configuration, the adjustment portion can be opened to a large water outlet to provide a maximum water discharge amount; and the large water outlet can be manually adjusted to form a non-maximum water discharge amount. At non-maximum water output, a large number of tiny bubbles can be sprayed.

According to the above configuration, the microbubble holes that are inserted through the switches can form concentric circles with the large water discharge holes and the microbubble generating portions. In this case, the water volume can be adjusted through the hole in the concentric circle of the switch, so that the adjustment portion can be more tight and firm.

The present invention enables the shower head to increase the amount of water generated while generating minute bubbles through a simple structure.

A seal ring (not shown) is provided between the head portion 11 and the grip portion 12.

The grip portion 12 has a cylindrical hollow portion therein. The lower periphery of the grip portion 12 is a spiral portion 12a for locking with the shower head hose. The liquid (for example, tap water) flows from the showerhead hose to the hollow portion of the grip portion 12.

As shown in Fig. 2(a), a water sprinkling member 40 is provided on the front surface of the head portion 11. The sprinkling member 40 is composed of a plurality of sprinkling holes 40a. The sprinkling hole 40a is radially spread on the sprinkling member 40. The head 11 is sprayed with tap water through the sprinkling hole 40a. In addition, a cover member 42 is embedded in the periphery of the sprinkling member 40.

As shown in Fig. 2(b), the back surface of the head portion 11 is provided with a rotary manipulation member 60. The rotation manipulation member 60 is constituted by the manipulation protrusion 60a. Holding the manipulation protrusion 60a, the rotation control member 60 can be rotated in the direction R depicted in Fig. 2(b) or in the opposite direction. The amount of water or the amount of fine bubbles can be adjusted by rotating the manipulation projection 60a.

Next, the internal structure of the head 11 will be described with reference to FIG.

As shown in FIG. 1, the head 11 has a body 15. The main body 15 is composed of a hollow cylindrical water inlet portion 15a, a bowl-shaped bowl-shaped side portion 15b, and a bottom portion 15c. The hollow water inlet portion 15a communicates with the hollow portion of the grip portion 12. The water inlet portion 15a is opened to connect the internal space formed by the bowl-shaped side portion 15b and the bottom portion 15c. In other words, the tap water that flows in from the hollow portion of the grip portion 12 flows into the internal space of the main body 15 through the water inlet portion 15a.

The bottom portion 15c is composed of a plurality of cylindrical fixing portions 15d (three in the embodiment) for fixing the connecting member 20 thereafter. Each of the fixing portions 15d protrudes from the sprinkling member 40 in the bowl-shaped side portion 15b (hereinafter referred to as an opening portion of the bowl-shaped side portion 15b), and the inside of the fixing portion 15d is engraved with a screw groove. The middle of the bottom portion 15c is a through hole 15e. The surface of the back surface of the bottom portion 15c has a plurality of recesses 15f for temporarily fixing The switch component 50 that is interlocked with the control unit 60 has a configuration corresponding to the number of water amount adjustment sections. In this embodiment, in response to the five-stage water discharge amount of the shower head 10, five recesses 15f are provided in the bottom portion 15c of the main body 15.

The inner space of the bowl-shaped side portion 15b of the main body 15 is provided with a connecting member 20 of a microbubble generating portion. As shown in FIG. 1, the connecting member 20 is embedded in the main body 15 through the sealing member 30. The connecting member 20 is composed of a plurality of fixing holes 20a. The connecting member 20 is fixed to the main body 15 by the bolts 31 being locked to the fixing portion 15d through the fixing holes 20a.

The connecting member 20 includes a disk-shaped body, a plurality of protruding portions 22 projecting from the opening of the bowl-shaped side portion 15b, and a central protruding portion 23 that protrudes from the center of the main body at the opposite surface of the protruding portion 22. The inside of each protruding portion 22 is a through hole 24 . The through hole 24 has a function of changing tap water into minute bubbles. In other words, in order to generate fine bubbles in the water passing through the through holes 24, the protruding portion 22 needs to have a certain length. The present invention is composed of seven through holes 24. The diameter of each of the through holes 24 increases toward the opening direction of the bowl-shaped side portion 15b. Therefore, when the tap water passes through the respective through holes 24, the gas contained in the tap water becomes fine bubbles due to the change in pressure. Tap water.

As shown in FIG. 3(a), the connecting member 20 has a large hole 25 having a larger diameter than the through hole 24. The large holes 25 are sized such that the running tap water does not generate minute bubbles in order to increase the water flow per unit time flowing through the connecting member 20 to increase the amount of water in the shower head 10. As shown in the front view of FIG. 3(b) and the cross-sectional view of FIG. 3(c), the water outlet portion of the connecting member 20 is provided with a diffusing member 25a for plugging the large hole 25. The water flowing out of the large holes 25 flows through the connecting member 20 while being diffused through the diffusing member 25a. Further, the amount of water discharged from the large holes 25 is assumed to be 20 times the amount of water discharged from the through holes 24 in which fine bubbles are generated. The detailed arrangement of the through holes 24 and the large holes 25 will be described later.

As shown in FIG. 1, a sprinkling member 40 is locked to the sprinkling member at the opening of the main body 15. The seal member 41 is between the sprinkling member 40 and the main body 15 (between the screw faces). The sprinkler component 40 has a bottomed cylindrical design and the bottom is a sprinkler hole 40a.

Further, a switch member 50 is provided on the back surface of the connecting member 20 (the opening of the main body 15 and its opposite surface). As shown in FIG. 4, the switch component 50 is integrally formed by the plate portion 51 and the joint boss portion 52. The plate-like portion 51 is a fan-shaped plate that is sandwiched by the engaging projections 52. As shown in FIG. 1, the plate portion 51 is fitted to the central projection 23 of the connecting member 20. This plate-like portion 51 is rotated about the central projection 23, and the plate-like portion 51 is large enough to close or open the through hole 24 and the large hole 25.

As shown in Fig. 1, the inner side of the engaging projection portion 52 of the switch member 50 is a projecting portion which is fitted in the opening of the spring seat member 55. The spring seat member 55 has an annular projection at the opening and the back surface. A spring 56 is pressed between the projection at the opening of the spring seat member 55 and the engaging projection 52 of the switch member 50. The bolt 58 passes through the raised opening at the back of the spring seat part 55. Between the spring seat part 55 and the bolt 58 is a seal ring part 57. A seal member 59 is provided between the projection on the back surface of the spring seat member 55 and the main body 15. The switch member 50 is locked in the center of the rotary manipulation member 60 by the bolts 58, and is integrated, so that it can be rotated in the main body 15. Therefore, once the rotary manipulation member 60 is rotated, the plate portion 51 of the switch member 50 presses the joint member 20 through the spring 56, and the rotary manipulation member 60 rotates together with the switch member 50.

Further, a concave portion 60b is provided on the rotational manipulation member 60 before the concave portion 15f of the main body 15. The recess 60b has a spring 61 therein and a latching member 62. The latch member 62 has a spherical shape and is pressed in the direction of the recess 60b by the spring 61. When the rotary manipulation member 60 is rotated, the latch member 62 is fitted into the recess 15f, at which position the rotary manipulation member 60 is temporarily caught. Therefore, the switch member 50 connected to the rotary manipulation member 60 is temporarily held at a position where the rotary manipulation member 60 is stuck. While the rotation control member 60 is rotating, if the switch member 50 is rotated in the direction in which the latch member 62 is pulled outward from the recess 15f, the switch member 50 is also rotated. The present invention includes a spring seat member 55, a spring 56, a seal member 57, 59 bolt 58 and an adjustment portion of the rotary control member 60 associated with the switch member 50.

Next, referring to FIG. 3, the arrangement of the through holes 24 and the large holes 25 in the connecting member 20. The through hole 24 referred to in the present invention includes seven through holes 24, 24a, 24b, 24c, 24d, 24a, 24f, and 24g, respectively. The through holes 24a to 24g are provided corresponding to the sector-shaped plate-like portion 51, and the through-holes 24 to be opened are disposed on the connecting member 20 so as to be distributed around the joint boss portion 52.

As shown in Fig. 3(a), the through hole 24 of the present invention is arranged in two layers concentrically. The outer ring has through holes 24a, 24b, and 24c, and the inner ring has through holes 24d, 24e, 24f, and 24g.

Based on the X axis from which the center point of the connecting member 20 extends, the through hole 24a on the outer circumference is located 90 degrees clockwise from the X axis, that is, a position of -90 degrees.

The through holes 24b and 24c are 90±α degrees (assuming α=30) in the counterclockwise direction from the X axis, and are provided separately from each other.

The through hole 24d is provided at a position that is clockwise by a degree of the x-axis, that is, a position of an angle -α degrees.

The through hole 24e is provided at a position 180°α in the counterclockwise direction from the X axis, that is, a position of an angle [180-α degree], and is in point symmetry with the through hole 24d.

The through hole 24f is provided at a position α1 in the counterclockwise direction from the X axis, that is, a position of an angle [α degree], and is in line symmetry with the through hole 24e.

The through hole 24g is provided between the circumferential lines 24e and 24f.

The position of the large hole 25 is located at an angle of [180 + α degrees] from the side. The position of the large hole 25 is approximately at the line symmetry position of the through hole 24d, and the through hole 24f is point symmetrical. Further, the large hole 25 is located inside the outer circle where the through holes 24a to 24c are located.

Next, referring to FIG. 5 and FIG. 6 regarding the water amount adjustment method of the shower head 10 configured as described above.

The invention is designed in a five-stage water discharge mode. The present invention will be described by taking the rotation control member 60 and sequentially increasing the amount of water from the first stage to the fifth stage as an example. Further, the shower head 10 of the present invention is generally a fourth stage in which a large amount of water is used, and a fifth stage in which the amount of water is the largest.

(Phase 1)

First, start with the first stage with the least amount of water.

As shown in Fig. 5(a), in the first stage, the plate-like portion 51 of the switch component 50 is stopped at the position where the large hole 25 and the through holes 24d to g are closed. At the same time, the through holes 24a to 24c are unobstructed. Therefore, the shower head 10 sprays tap water containing fine bubbles in the amount of water flowing through the through holes 24a to 24c.

(Phase 2)

From the state of the first stage, the rotation control member 60 is rotated in the direction of R, and the latch member 62 is pulled outward from the concave portion 15f to be fitted into the next concave portion 15f. The switch member 50 rotates as the rotational control member 60 rotates and engages. In the second stage, as shown in FIG. 5(b), the plate-like portion 51 of the switch component 50 is stopped at a position where the large hole 25 and the through holes 24a and 24f are covered. At this time, the through holes 24a to 24d and 24g are unobstructed. Therefore, the shower head 10 sprays tap water containing fine bubbles by the amount of water flowing through the through holes 24a to 24d and 24g. Compared with the first stage, the amount of water discharged at this time is greater than the amount of water discharged through the through holes 24d and 24g.

(Phase 3)

From the state of the second stage, the rotation control member 60 is again rotated in the direction of R, and the latch member 62 is pulled outward from the concave portion 15f to be fitted into the next concave portion 15f. In the third stage, as shown in FIG. 5(c), the plate-like portion 51 of the switch component 50 is stopped at a position where the large hole 25 and the through hole 24f are covered. At this time, the through holes 24a to 24e and 24g are unobstructed. Therefore, the shower head 10 sprays tap water containing fine bubbles by the amount of water flowing through the through holes 24a to 24e and 24g. Compared with the second stage, the amount of water discharged at this time is greater than the amount of water discharged from the through hole 24e.

(Phase 4)

From the state of the third stage, the rotation control member 60 is again rotated in the direction of R, and the latch member 62 is pulled outward from the recess 15f to be fitted into the next recess 15f. In the fourth stage, as shown in Fig. 6(a), the plate-like portion 51 of the switch component 50 is stopped at a position where only the large hole 25 is covered. At this time, the through holes 24a to 24g are unobstructed. Therefore, the shower head 10 sprays tap water containing fine bubbles by the amount of water flowing through the through holes 24a to 24g. Compared with the third stage, the amount of water discharged at this time is greater than the amount of water discharged through the through hole 24f.

(Phase 5)

From the state of the fourth stage, the rotation control member 60 is again rotated in the direction of R, and the latch member 62 is pulled outward from the recess 15f to be fitted into the next recess 15f. In the fifth stage, as shown in Fig. 6(b), the plate-like portion 51 of the switch component 50 is stopped at a position where only the through hole 24g is covered. At this time, the through holes 24a to 24f and the large holes 25 are unobstructed. Therefore, the shower head 10 sprays tap water containing fine bubbles by the maximum amount of water flowing through the through holes 24a to 24f and the large holes 25. Compared with the fourth stage, the amount of water at this time will exceed the amount of water from the large hole 25, that is, the maximum amount of water that becomes the shower head 10.

The present invention achieves the following effects.

(1) The shower head 10 of the present invention is provided with a connecting member 20 on the main body 15. A plurality of through holes 24 and large holes 25 which function as minute cells are formed in the connecting member 20. Therefore, when the shower head 10 has the maximum water discharge amount, both the through hole 24 and the large hole 25 can simultaneously supply water to the sprinkling member 40, so that the amount of water can be increased.

(2) The connecting portion 20 of the present invention is provided with a protruding portion 22 having a through hole 24 therein. When tap water flows through The pores 24, through the change of the pressure, the gas originally dissolved in the tap water becomes tiny bubbles, which are mixed in the tap water. Therefore, in the connecting member 20, the wall of the through hole 24 can be thinned, and the water containing the fine bubbles can be sprinkled by the simple structure in which the shower head 10 is lightweight.

(3) The connecting member 20 of the present invention is provided with through holes 24a to 24c in the outer ring and inner ring through holes 24d to 24g which are covered by the permeable switch member 50. Further, the connecting member 20 also has a large hole 25 inside the outer ring through holes 24a to 24c. The amount of water can be adjusted by the simple configuration in which the inner ring through holes 24d to 24g and the large holes 25 are sequentially covered by the switch member 50.

(4) Regarding the shower head 10 of the present invention, the first stage is to open the through holes 24a to 24c; the second stage is to open the through holes 24a to 24d, 24g; the third stage is to open the through holes 24a to 24e, 24g; At the stage, the through holes 24a to 24g are unblocked, and only the large holes 25 are covered. The fifth stage of the maximum water discharge is to open the through holes 24a to 24f and the large holes 25. Therefore, regardless of the stage, the unobstructed through-holes are uniformly dispersed on the connecting member 20, so that the problem that the water discharge portion is biased to somewhere can be avoided.

(5) Regarding the shower head 10 of the present invention, the switch member 50 is designed on the back surface of the connecting member 20. When the shower head 10 is used, the connecting member 20 can plug the hose side of the shower head (the shower head), that is, directly adjust the water amount from the source of the tap water.

(change example)

Further, the present invention can be embodied by the following modifications.

According to the above invention, seven through holes 24a to 24g for generating fine bubbles and one large hole 25 are provided in the connecting member 20. The number of through holes 24 that generate fine bubbles and the number of large holes 25 can be adjusted and changed. For example, more than one large hole 25 can also be provided. At this time, the maximum water output is to open the large hole 25. If you want to increase the content of tiny bubbles, cover the large holes 25. In addition, the arrangement of the through holes 24 is not limited to two concentric circles.

According to the above invention, the shape of the plate portion 51 of the switch component 50 is designed to be able to penetrate the inner ring The holes 24d~24g are sequentially covered. However, as long as the through hole can be covered, it is possible to design the shape of the plate portion 51 of the switch member 50. For example, it is also possible to design such that the through holes 24a to 24c of the outer ring can be appropriately covered to adjust the amount of water discharged.

According to the above invention, the plate-like portion 51 of the switch component 50 is designed to be rotated to adjust the amount of water. As long as each of the through holes can be plugged, it is not necessarily limited to pass through the switch member 50. For example, it is also possible to change the number of holes to be covered by adjusting the number of holes to be covered by the switching member 50 in conjunction with the connecting member 20.
