Abstract
Description
Technical Field
[0001] The present invention enables a shower head in use or newly purchased to have a high-functional fine bubble water generation function with simple operation by a user, and enables the user to easily select and replace any one of a plurality of types of shower heads during shower use. The present invention relates to a shower head for fine bubble water.
Background Art
[0002] In the present application, fine bubbles mean microbubbles with a diameter of approximately 100 μm or less and fine bubbles with a diameter of about 50 to 500 nm, and fine bubble water means bubble water in tap water that contains many such micro-sized bubbles.
[0003] [[ID=,16]]Fine bubble water not only effectively penetrates the skin surface with bubble water finer than the pore diameter of the human face and body, but also the detergent fine particles such as solid soap, liquid soap or shampoo adhere to the surface of the bubbles in the water and penetrate finely into the skin cells and pores, thereby improving the cleaning power of water or detergent.
[0004] Thus, fine bubble water penetrates into human pores, sweat glands, and skin tissues, effectively removes dirt and lipids, and improves blood circulation. Therefore, in recent years, it has attracted attention and been used particularly in the fields of beauty and health.
[0005] To generate water containing a large amount of such fine bubbles, a high-speed shearing method, a pressure crushing method, a cavitation method, etc. are known. Most of them suck air from the outside by an aspirator method or the like, or forcibly inject it. As one of them, a microbubble generator is known that causes cavitation in a casing with a mixed fluid composed of a liquid accelerated by an accelerating means and a gas (bubbles with a diameter of about several millimeters) introduced into the casing by a gas-liquid mixing means to generate microbubbles (for example, see Patent Document 1).
[0006] Furthermore, a microbubble generator is known that generates microbubbles by cavitation from so-called dissolved air dissolved in water without drawing in air from the outside, and has a first nozzle on the water inlet side that gradually decreases in cross-sectional area perpendicular to its central axis from the inlet to the outlet, a second nozzle on the water outlet side that is continuously arranged via a connecting passage provided from the outlet of the first nozzle and gradually increases in cross-sectional area perpendicular to its central axis from the inlet to the outlet, and a gap or side chamber that opens only to the connecting passage (see, for example, Patent Document 2).
[0007] Furthermore, showerheads that utilize a microbubble generator, which generates microbubbles from dissolved air in water using a cavitation method, for beauty and health benefits are known (see, for example, Patent Document 3).
[0008] For reference, Patent Document 4, relating to the components of the present invention, shows a known example of a coupler joint type joint consisting of a joint plug used in a washing machine or the like of the present invention and a joint socket detachably connected to the joint plug. [Prior art documents] [Patent Documents]
[0009] [Patent Document 1] Japanese Patent Publication No. 2007-021343 [Patent Document 2] Japanese Patent Publication No. 2009-136864 [Patent Document 3] Japanese Patent Publication No. 2016-002196 [Patent Document 4] Japanese Patent Publication No. 2010-196812 [Overview of the Initiative] [Problems that the invention aims to solve]
[0010] However, the microbubble generator described in Patent Document 1, which uses gas-liquid mixing by accelerating water stored in a tank, results in a large device that is unsuitable for typical household shower facilities directly connected to water pipes.
[0011] Furthermore, the microbubble generator described in Patent Document 2 reduces the water pressure by throttling the rapidly expanding water flow in the connecting passage equipped with a side chamber at the second nozzle, which can cause a decrease in water pressure and prevent the supply of a sufficient amount of water. For this reason, the width of the side chamber in the axial flow direction must be adjusted according to the water pressure conditions, making it unsuitable for installation in the shower equipment of a typical household bathroom.
[0012] Patent Document 3 describes a household shower head that generates microbubble water, but the microbubble generator is pre-built into the shower head and is not configured to allow the fine bubble generator to be attached to existing shower heads or shower equipment such as ordinary shower heads.
[0013] Therefore, the present invention aims to provide a fine bubble water shower head that allows users to easily add a high-performance fine bubble water generation function to their existing or newly purchased shower heads through simple manual work, and that allows users to easily replace any one of several types of shower heads provided in advance, depending on the part of the body being showered, such as the body or hair, and according to the user's preference. [Means for solving the problem]
[0014] To solve the above problems, the present invention, in its first aspect, provides a fine bubble water generator for discharging fine bubble water, which is made by atomizing bubbles contained in tap water, from a shower head, comprising: a first adapter having a shower head connection port that fits the water inlet of a shower head and a joint plug that constitutes a coupler joint type fitting; and a second adapter having a shower hose connection port that fits the water outlet of a shower hose that supplies tap water to the shower head and a joint socket that is detachably connected to the joint plug, wherein the first adapter comprises a first mechanism that constitutes a fine bubble water generator, and the second adapter comprises a second mechanism that constitutes the fine bubble water generator, and the first adapter and the second adapter form the fine bubble water generator by joint coupling the joint plug and the joint socket.
[0015] Furthermore, in a second aspect thereof, the present invention provides a shower head that releases fine bubble water, which is made by atomizing bubbles contained in tap water, wherein a first adapter having a joint plug constituting a coupler joint type fitting is attached to the water inlet of the shower head, and a second adapter having a joint socket detachably connected to the joint plug is attached to the water outlet of the shower hose that supplies tap water to the shower head, wherein the first adapter comprises a first mechanism constituting a fine bubble water generator, and the second adapter comprises a second mechanism constituting the fine bubble water generator, and the joint plug and the joint socket are jointly connected so that the first adapter and the second adapter form the fine bubble water generator.
[0016] Furthermore, in a third aspect thereof, the present invention provides a shower head with a shower hose comprising a shower head that releases fine bubble water, which is made by atomizing bubbles contained in tap water, and a shower hose that supplies tap water to the shower head, wherein a first adapter having a joint plug constituting a coupler joint type fitting is attached to the water inlet of the shower head, and a second adapter having a joint socket that is detachably connected to the joint plug is attached to the water outlet of the shower hose, the first adapter comprises a first mechanism constituting a fine bubble water generator, and the second adapter comprises a second mechanism constituting the fine bubble water generator, and the joint plug and the joint socket are jointly connected so that the first adapter and the second adapter form the fine bubble water generator.
[0017] Here, the most important features common to the inventions according to the first, second, and third embodiments described above are: a) A first adapter having a shower head connection port that fits the water inlet of a shower head and a joint plug that constitutes a coupler joint type fitting, and a second adapter having a shower hose connection port that fits the water outlet of a shower hose that supplies tap water to the shower head and a joint socket that is detachably connected to the joint plug, b) The second mechanism constituting the fine bubble water generator in the second adapter comprises an inlet surface having a plurality of branching holes for branching the tap water supplied from the shower hose, and a cylindrical water passage for passing the tap water flowing in from the inlet surface. The first mechanism constituting the fine bubble water generator in the first adapter comprises an outlet surface having a plurality of branching holes for branching the tap water flowing out from the water passage, and the inner wall of the water passage has irregularities formed by spiral cuts, so that the water flowing in from the plurality of branching holes in the inlet surface comes into contact with and collides with the spiral irregularities, creating turbulence in the water passage, which finely crushes the bubbles in the tap water, causing fine bubble water to flow out from the plurality of branching holes in the outlet surface.
[0018] As a result, the present invention allows users to easily attach and detach a shower hose with a second adapter to multiple types of individual shower heads, each of which has a first adapter pre-attached to it. This enables users to easily add a high-performance fine bubble water generation function to their existing or newly purchased shower heads through simple manual operation. Furthermore, it allows users to easily select and replace any one of the multiple types of shower heads provided, depending on the part of the body or hair being showered.
[0019] Furthermore, the system allows users to easily replace multiple showerheads by selecting one from a variety of pre-prepared showerheads to suit their preferences.
[0020] Incidentally, the number of branching holes in the water inlet surface of the second mechanism for branching the tap water supplied from the shower hose is 4, and the number of branching holes in the water outlet surface of the first mechanism for branching the tap water flowing out from the water passage is 3.
[0021] Water ejected from four branch holes that branch the tap water supplied from the shower hose is narrowed down to three branch holes that branch the tap water flowing out from the water passage in the water outlet surface body of the first mechanism part, which is less than that.
[0022] As a result, by flowing through the water passage with the pressure of the water in the water passage increased, it contacts and collides with the spiral uneven parts formed on the inner wall surface of the water passage, and finer bubbles are formed more effectively.
[0023] Here, each of the branch holes provided in the water inlet surface body is inclined by a predetermined angle with respect to the central axis of the water passage. As a result, the tap water that has entered from the water inlet surface body collides with the spiral uneven surface of the water passage at a predetermined angle, and more and more efficiently generated fine bubbles.
[0024] By the way, each of the branch holes provided in the water inlet surface body is arranged at equal intervals at positions separated by a predetermined distance from the center of the water inlet surface body. As a result, the tap water that has entered from the water inlet surface body is dispersed on the uneven surface of the water passage in a uniformly dispersed state.
[0025] Furthermore, similar to the water inlet body, each of the branch holes provided in the water outlet surface body is inclined by a predetermined angle with respect to the central axis of the water passage. As a result, the fine bubble water is supplied in a state of being dispersed in the water passage in the shower head.
[0026] And, similar to the water inlet body, each of the branch holes provided in the water outlet surface body is arranged at equal intervals at positions separated by a predetermined distance from the center of the water outlet surface body. As a result, it is supplied in a state of being uniformly dispersed from the water outlet surface body into the water passage in the shower head.
[0027] In addition, it is desirable that the thickness dimension of the water inlet surface body and the thickness dimension of the water outlet surface body are 1 / 4 or more of the diameter of the water passage.
[0028] Furthermore, it is desirable that the center positions of the branch holes in the inlet and outlet surfaces are offset from the direction of the central axis of the water channel. This enhances the turbulence of the tap water within the water channel, thereby increasing the efficiency of fine bubble generation. [Effects of the Invention]
[0029] As its first effect, the present invention allows users to easily attach and detach a shower hose with a second adapter to multiple types of individual shower heads, each of which has a first adapter pre-attached to it. This enables users to easily add a high-performance fine bubble water generation function to their existing or newly purchased shower heads through simple manual operation. Furthermore, it allows users to easily select and replace any one of the multiple types of shower heads provided, depending on the part of the body or hair being showered.
[0030] Furthermore, the system allows users to easily replace multiple showerheads by selecting one from a variety of pre-prepared showerheads to suit their preferences.
[0031] Furthermore, as a second effect of the present invention, it is possible to equip existing or newly purchased shower heads with a high-performance fine bubble water generation function through simple user operations, such as attaching the first adapter to the shower head and the second adapter to the shower hose, while the shower hose connected to the shower head is removed. [Brief explanation of the drawing]

[Figure 6] Examples of different types of shower heads 10 to which the first adapter 11 is connected are shown. [Figure 7] This example shows a water inlet hole 14-1 drilled in the water inlet surface 14 at an angle of α with respect to the water flow direction H of the water passage 14-4 (see Figure 5). [Modes for carrying out the invention]
[0033] The fine bubble water generating device for shower heads according to the present invention will be described in detail below with reference to the drawings.
[0034] Figure 1 shows an example of the appearance of a shower head according to the present invention, where (a) shows the shower head 10 to which the first adapter 11 is connected, coupled to the shower hose 15 to which the second adapter 12 is connected by a coupler joint type fitting, and (b) shows the shower head 10 to which the first adapter 11 is connected, detached from the shower hose 15 to which the second adapter 12 is connected by a coupler joint type fitting.
[0035] The existing showers 10 and 13 currently in use by the user are configured such that the shower head 10 is screw-connected to the shower hose 15.
[0036] To enable the user to use the shower with the microbubble water generation function according to the present invention, first, remove the shower head 10 from the shower hose 15, and as shown in Figure 1(b), screw the first adapter 11 onto the male thread (not shown in Figure 1, but the same as the technical specifications of the male thread 12-1 of the second adapter 12 shown in Figure 2) provided on the water inlet surface of the existing shower head 10, and screw the second adapter 12 onto the female thread (not shown in Figure 1, but the same as the technical specifications of the female thread 11-1 of the first adapter 11 shown in Figure 2) provided on the water outlet surface of the existing shower hose 15 from which the shower head 10 was removed.
[0037] Then, as shown in Figure 1(a), the shower hose 15+12, to which the first adapter 12 is attached, is connected to the shower head 10+11, to which the first adapter 11 is attached, using a coupler joint to create the shower 10+13 having a microbubble water generation function according to the present invention.
[0038] Figure 2 shows an example of the appearance of the first adapter 11 and the second adapter 12 that constitute the fine bubble water generating device according to the first embodiment of the present invention.
[0039] Figure 2(a) shows the state in which the first adapter 11 and the second adapter are connected as a coupler joint type joint, and Figure 2(b) shows the state in which the first adapter 11 and the second adapter are separated. Here, the joint plug 11-4 of the first adapter 11 and the joint socket 12-3 of the second adapter 12 shown in Figure 2(b) constitute the coupler joint type joint.
[0040] Furthermore, part 2(c) shows the shape of the water outlet body 13 as seen from the water outlet side (upper part of the figure) of the first adapter 11 shown in part 2(a), and part 2(d) shows the shape of the water inlet body 12 as seen from the water inlet side (lower part of the figure) of the second adapter 12 shown in part 2(b).
[0041] As shown in Figures 1 and 2(a) and 2(b), the shower head 10 (Figure 1) is fitted with a first adapter 11 having a joint plug 11-4 that constitutes a joint-type fitting with the second adapter 12, which will be described later. Furthermore, the outlet of the shower hose 15 (Figure 1) that supplies tap water to the shower head 10 is connected to the second adapter 12, which has a joint socket 12-3 that is detachably connected to the joint plug 11-4 of the first adapter 11 connected to the shower head 10.
[0042] As a result, the first adapter 11, which is screwed onto the shower head 10, and the second adapter 12, which is connected to the shower hose 15, form a coupler joint type fitting, allowing the user to attach and detach the shower head 10 to the shower hose 15 with a single touch.
[0043] The coupler joint type fitting is, for example, a joint type fitting consisting of a joint plug connected to the water inlet to the washing machine and a joint socket connected to the washing machine hose that fits into the joint plug in a one-touch manner. For example, such a fitting is widely known from "Japanese Patent Publication No. 2010-196812" (Patent Document), and will not be described in detail here.
[0044] Furthermore, in the present invention, as will be described later, the first adapter 11 is equipped with a first mechanism that constitutes a fine bubble water generator, and the second adapter 12 is equipped with a second mechanism that constitutes a fine bubble water generator. The joint plug 11-4 of the first adapter 11 and the joint socket 12-3 of the second adapter 12 are connected by a joint, so that the first adapter 11 and the second adapter 12 form a fine bubble water generator.
[0045] Here, the first mechanism constituting the fine bubble water generator housed in the first adapter 11 is specifically an outlet surface 13 (see Figure 5) having multiple branch holes 13-1 of the fine bubble water generator formed by fitting the first adapter 11 and the second adapter 12 together, and the second mechanism constituting the fine bubble water generator housed in the second adapter 12 incorporates an inlet surface 14 having multiple branch holes 14-1 for branching the tap water supplied from the shower hose 15, and a cylindrical water passage 14-4 (see Figure 5) for passing the tap water that flows in from the branch holes of the inlet surface 14.
[0046] Figure 3 shows an example of the internal structure of the first adapter 11 connected to the shower head 10. Part 3(a) shows the shape of the first adapter 11 as seen from the water outlet side (top of the figure), part 3(b) shows the side view of the first adapter 11, and part 3(c) shows the internal structure of the first adapter.
[0047] As shown in Figure 3(a), when viewed from the water outlet side (upper part of the figure) of the first adapter 11, the water outlet body 13 and the three water outlet holes 13-1 provided in the water outlet body 13 are visible. As previously described, the first adapter 11 includes a connection part 11-1 that is screwed into the shower head 10, a joint plug 11-4 that forms a joint-type fitting with the second adapter 12 (Figure 4), and the water outlet body 13 of the first mechanism that constitutes the fine bubble water generator.
[0048] Figure 4 shows an example of the internal structure of a second adapter 12 connected to a shower hose 15, where (a) shows a side view of the second adapter 12, (b) shows the internal structure of the second adapter 12, and (c) shows the shape of the second adapter 12 as seen from the water inlet side (bottom of the figure).
[0049] As shown in Figure 4(a), the second adapter 12 connected to the shower hose 15 has a joint socket 12-3 (see Figure 4(b)) housed on its upper surface that fits into the joint plug 11-4 which constitutes the joint fitting of the first adapter 11, and a connecting portion 12-1 that is screwed into the shower hose 15.
[0050] Figure 4(b) shows the internal structure of the second adapter 12. As shown in the figure, tap water entering from the shower hose 15 (see Figure 1) through the inlet surface 12-2 of the second adapter 12 flows in through the inlet surface body 14, which has a plurality of branch holes 14-1 located inside the connection part 12-1, and enters the cylindrical water passage 14-4 (see Figure 5). The inner wall surface of the water passage 14-4 has a spiral groove 14-5 formed by spiral cuts. The tap water flowing in from the plurality of branch holes 14-1 of the inlet surface body 14 comes into contact with and collides with the spiral groove 14-5, creating turbulence within the water passage 14-4. The air bubbles in the tap water are then finely crushed and sent to the first adapter 11 side via the joint socket 12-3 and the joint plug 11-4 of the first adapter 11.
[0051] Figure 4(c) is a view of the second adapter 12 from the water inlet surface 14 side, and in the illustrated example, the water inlet surface 14 is provided with four branching holes.
[0052] Figure 5 schematically illustrates the state in which a fine bubble water generator is formed when the first adapter 11 and the second adapter are connected by a coupler joint type fitting.
[0053] Figure 5(a) schematically illustrates how tap water supplied from the shower hose 15 (see Figure 1) enters through the branch hole 14-1 of the inlet surface 14 constituting the second adapter 12, passes through the water passage 14-4 at a predetermined angle, contacts and collides with the spiral notches and uneven surfaces 12-5 on the inner circumferential wall of the water passage 14-4, passes through the coupler joint section 11-4 formed by the joint plug 11-4 of the first adapter 11 and the joint socket 12-3 of the second adapter 12, passes through the branch hole 13-1 of the outlet surface 13 constituting the first adapter 13, and is supplied to the shower head (see Figure 1) as fine bubble water.
[0054] As shown in part 5(b), the mounting position of the second adapter 12 and the four branch holes 14-1 of the water inlet body 14 are shown, and the mounting position of the first adapter 11 and the three branch holes 13-1 of the water outlet body 13 are shown.
[0055] Figure 5(c) shows the spiral-shaped notches and resulting uneven surface 12-4 provided on the inner circumferential wall of the water passage 12-5 within the second adapter 12.
[0056] Incidentally, the multiple branch holes provided in the inlet surface 14 and the outlet surface 13 are each arranged at equal intervals at a predetermined distance from the center of the inlet surface. Furthermore, at least the branch hole 14-1 provided in the inlet surface 14 is drilled at an angle to the central axis of the water passage 14-4.
[0057] Then, as shown in Figure 7, when viewed from the direction of the central axis of the water channel 14-4, the center positions of the branch holes 14-1 (4 holes in the example of Figure 5) and 13-1 (3 holes in the example of Figure 5) in the inlet surface 14 and outlet surface 13 are offset by a predetermined angle so that they do not coincide.
[0058] As shown in Figure 7, the water inlet hole 14-1 made in the water inlet surface 14 may be drilled straight with respect to the water flow direction H of the water passage 14-4 (see Figure 5), or, as shown in Figure 7, it may be drilled at an angle of α with respect to the water flow direction H.
[0059] As shown in Figure 7, when the holes are drilled at an angle of α with respect to the water flow direction H, the water flowing in from the three branch holes 14-1 of the inlet surface 14 comes into contact with and collides with the spiral-shaped irregularities 12-5 on the inner wall of the water channel 14-4, creating turbulence within the water channel 12-4. This causes the bubbles in the tap water to be finely crushed, resulting in a large amount of fine bubble water flowing out from the multiple branch holes 13-1 of the outlet surface 13-1.
[0060] Here, the thickness of the inlet surface 14 is set to, for example, 1 / 4 or more of the diameter of the water passage 13-4, so that the water flowing in from the multiple branch holes 14-1 of the inlet surface 14-1 strikes the inner wall of the water passage 13-4 at a sharp angle due to the spiral-shaped protrusions.
[0061] Similarly, in the water outlet surface 13, the holes are drilled at a predetermined angle with respect to the central axis of the water passage 14-4, so that the tap water flowing into the shower head 10 flows into the water inlet of the shower head 10 at a sharp angle, which makes it possible to further enhance the generation of nanobubble water (this is not shown here as it is obvious).
[0062] In this case, the outlet surface 13 should also be made, for example, 1 / 4 or more of the diameter of the water passage 13-4, similar to the inlet surface 14, so that the water flowing in from the multiple branch holes 14-1 of the inlet surface 14-1 strikes the spiral grooves on the inner wall of the inlet inside the shower hose 15 at a sharp angle.
[0063] Thus, if the number of branching holes in the inlet surface 14 that branch off the tap water supplied from the shower hose 15 is set to 4, and the number of branching holes in the outlet surface 13 that allow tap water to flow out of the water passage 14-4 is set to 3, the water ejected from the 4 branching holes that branch off the tap water supplied from the shower hose 15 will be narrowed down to a smaller number of branching holes, 3, that branch off the tap water flowing out of the water passage 14-4 in the outlet surface 13. As a result, the water in the water passage 14-4 flows through the water passage 14-4 with increased pressure, causing the tap water to collide forcefully with the spiral-shaped uneven surface 14-5 in the water passage 14-4, thereby increasing the generation of fine bubbles.
[0064] Figure 6 shows examples of different types of shower heads 10 to which the first adapter 11 is connected.
[0065] As shown in Figure 6, by preparing shower heads with the first adapter 11 pre-attached to each of the multiple shower heads used by the family, the shower hose 15 (see Figure 1) with the second adapter 12 attached can be attached and detached with a single touch each time the shower is used. This allows the user to easily add a high-performance fine bubble water generation function to the shower head 10 currently in use or a newly purchased shower head 10 with simple manual work by the user themselves. Furthermore, it allows the user to easily select and replace any one of the multiple types of shower heads pre-prepared according to the part of the body or hair being showered.
[0066] Furthermore, the system allows users to easily replace multiple showerheads by selecting one from a variety of pre-prepared showerheads according to their preferences.
[0067] As described above, the present invention comprises a first adapter 11 connected to a shower head that fits the water inlet of the shower head 10 and having a joint plug 11-4 that constitutes a coupler joint type fitting, and a second adapter 12 connected to the water outlet of a shower hose that supplies tap water to the shower head 10 and having a joint socket 12-3 that is detachably connected to the joint plug 11-4, and a second mechanism constituting a fine bubble water generator in the second adapter 12, having a water inlet surface 14 having a plurality of branch holes 14-2 that branch the tap water supplied from the shower hose 15, and passing the tap water that flows in from the water inlet surface 14 The first mechanism, which constitutes the fine bubble water generator in the first adapter 13, is composed of a cylindrical water passage 14-4 and a water outlet surface having a plurality of branch holes 13-1 that branch the tap water flowing out of the water passage 14-4. Furthermore, a spiral-shaped notch-shaped uneven portion 13 is formed on the inner wall of the water passage, and the tap water flowing in from the plurality of branch holes 14-1 of the water inlet surface 14 comes into contact with and collides with the spiral-shaped uneven portion 12-5, creating turbulence in the water passage 14-4.
