Description

Technical Field

[0001] The present invention generally relates to the technical field of water outlet devices, and in particular to a bubble water generating device capable of generating microbubbles. Background Art

[0002] In the prior art, a shower head produces microbubble water by increasing the water temperature, thereby reducing the solubility of air in water and precipitating bubbles through expanded holes, thereby obtaining microbubble water. However, this method requires specific hot water conditions to achieve a good microbubble effect. When used under normal temperature water conditions, the shower head does not produce good microbubble effects.

[0003] There are some showers in the prior art that produce microbubble water by inhaling air, but the air intake of such showers is not automatically adjusted according to the amount of water intake, or can only be adjusted manually, which makes it inconvenient to use and the user experience is not good. At the same time, the manual adjustment of the air intake has a certain hysteresis, resulting in poor microbubble effect of the generated microbubble water.

[0009] According to one embodiment of the present invention, the at least one first water inlet hole includes a plurality of first water inlet holes, the plurality of first water inlet holes are formed on the first disk portion and penetrate the first surface and the second surface, the plurality of first water inlet holes are evenly arranged along the circumference of the first disk portion with the central axis as the center and are located in the area surrounded by the cylinder portion, and the inlet flow channel is formed on the first disk portion and penetrates the first surface and the second surface and is located outside the area surrounded by the cylinder portion.

[0010] According to one embodiment of the present invention, the mixer includes a second disk portion and an annular wall portion, wherein the second disk portion defines a central axis and includes a third surface and a fourth surface facing each other, and the annular wall portion surrounds the periphery of the second disk portion and protrudes from the third surface and the fourth surface.

[0011] According to one embodiment of the present invention, the diverter includes a first disc portion and a barrel portion, and the annular wall portion protrudes from the third surface of the second disc portion to form an accommodating space. When the diverter is assembled with the mixer, the first disc portion is accommodated in the accommodating space.

[0012] According to an embodiment of the present invention, the third surface of the second disk portion has an annular groove, and when the diverter and the mixer are assembled, the annular groove forms the first chamber.

At the same time, since the air intake of the outside air is effectively controlled, the bubbles in the mixed water flow with a certain number of bubbles are smaller, and then the bubble water generating device can generate bubble water with micro bubbles.

It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". Other relative terms such as "top", "bottom", etc. are also used to have similar meanings. The terms "one", "an", "the" and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to indicate an open-ended inclusive meaning and mean that there may be additional elements / components / etc. in addition to the listed elements / components / etc.; the terms "first", "second", "third" and "fourth" are used only as labels and are not quantitative restrictions on their objects.

[0073] The inventor of the present invention has found in research that there are some bubble water generating devices in the related art, which suck air into the bubble water generating device by suction and mix it with water to form a water flow with bubbles, and finally produce bubble water, but the bubble water generated by this bubble water generating device is not good. The inventor of the present invention has found that because this type of bubble water generating device cannot control the amount of air intake well, excessive intake of air causes the bubbles in the water flow to be larger, and no microbubbles with a high concentration are formed, resulting in a poor user experience.

[0074] Based on this, the present invention provides a bubble water generating device, comprising a diverter, a mixer, an inlet flow channel and a water outlet cover, the diverter comprising at least one first water inlet hole; a first chamber is formed between the mixer and the diverter, the mixer comprising at least one second water inlet hole and at least one reflux hole, the at least one second water inlet hole corresponds one-to-one to the at least one first water inlet hole, and the flow area of ​​each second water inlet hole is larger than the flow area of ​​the corresponding first water inlet hole, the at least one reflux hole, the at least one first water inlet hole and the at least one second water inlet hole are all connected to the first chamber; the inlet flow channel is connected to the first chamber; a second chamber is formed between the water outlet cover and the mixer, the at least one second water inlet hole and the at least one reflux hole are all connected to the second chamber.

[0075] The water flows through the first water inlet hole and the second water inlet hole in sequence. Since the flow area of ​​the second water inlet hole is larger than the flow area of ​​the first water inlet hole, according to the Bernoulli principle, a certain negative pressure will be generated in the second water inlet hole, so that the outside air passes through the inlet flow channel and the first chamber in sequence and is sucked into the second water inlet hole, and forms a mixed water flow with a certain number of bubbles with the water flow. After the mixed water flow enters the second chamber, a part of the mixed water flow will return to the first chamber through the reflux hole, and then be sucked into the second water inlet hole, and so on. Since the mixed water flow of part of the return will fill the first chamber during the reciprocating cycle, it will prevent the outside air from being sucked into the bubble water generating device, which plays a role in reducing the air intake. As the part of the mixed water flow is sucked into the second water inlet hole again, when the first chamber is not filled with the mixed water flow, the outside air continues to be sucked, thereby achieving the effect of automatically controlling the air intake of the outside air. At the same time, since the air intake of the outside air is effectively controlled, the bubbles in the mixed water flow with a certain number of bubbles are smaller, and then the bubble water generating device can generate bubble water with micro bubbles.

[0076] The structures, connection modes and functional relationships of the main components of the bubble water generating device proposed by the present invention are described in detail below with reference to the accompanying drawings.

[0077] It should be understood that the term “connected” in the present application may refer to an embodiment in which one or more components are in direct contact with each other, and may also include an embodiment in which additional features may be inserted.

[0078] like Figures 1 to 3 As shown, Figure 1 is an exploded view of an exemplary embodiment of the bubble water generating device of the present invention, Figure 2 is a side view of an exemplary embodiment of the bubble water generating device of the present invention, Figure 3 1 is a cross-sectional view of an exemplary embodiment of the bubble water generating device of the present invention, wherein the cross-sectional plane is cut along the axis of the shower head. In an exemplary embodiment, the shower head provided by the present invention includes a water inlet assembly 10, a diverter 30, a mixer 50, a filter assembly 70 and a water outlet cover 90.

[0079] like Figure 3 As shown, the water inlet assembly 10 is connected to the diverter 30, the diverter 30 is connected to the mixer 50, the water outlet cover 90 is connected to the mixer 50, a second chamber 80 is formed between the water outlet cover 90 and the mixer 50, and the filter assembly 70 is arranged in the second chamber 80 and close to the water outlet cover 90.

[0080] The water inlet assembly 10 includes a first ring portion 110 and a second ring portion 120, which together form a water inlet channel 101. The first ring portion 110 has an external thread 111 on its exterior for connection with a water inlet pipe (not shown) or other components providing a water source, and the second ring portion 120 has an internal thread 121 for threaded connection with the diverter 30. A sealing ring 20 is also provided at the connection between the second ring portion 120 and the diverter 30 to prevent water from leaking from the connection between the two.

[0081] like Figure 4 and Figure 5 As shown, Figure 4 is a top view of an exemplary embodiment of a diverter of a bubble water generating device of the present invention, Figure 5 yes Figure 4 In an exemplary embodiment, the flow divider 30 includes a first disk portion 310 and a barrel portion 320, the first disk portion 310 defines a central axis L, the flow divider 30 includes a first surface 311 and a second surface 312 opposite to each other, the barrel portion 320 is perpendicular to the first disk portion 310 and extends from the first surface 311 to a direction away from the second surface 312 with the central axis L as an axis, and the outer portion of the barrel portion 320 has an external thread 321 for threaded connection with the water inlet assembly 10.

[0082] The flow divider 30 includes a plurality of first water inlet holes 313 and an inlet flow channel 314, and the plurality of first water inlet holes 313 are connected to the water inlet flow channel 101. The plurality of first water inlet holes 313 are formed on the first disc portion 310 and penetrate the first surface 311 and the second surface 312, the plurality of first water inlet holes 313 are uniformly arranged along the circumference of the first disc portion 310 with the central axis L as the center, and the plurality of first water inlet holes 313 are located in the area surrounded by the cylinder portion 320, and the inlet flow channel 314 is formed on the first disc portion 310 and penetrates the first surface 311 and the second surface 312, and the inlet flow channel 314 is located outside the area surrounded by the cylinder portion 320.

[0083] like Figure 6 and Figure 7 As shown, Figure 6 is a top view of an exemplary embodiment of a mixer of a bubble water generating device of the present invention, Figure 7 yes Figure 6 In an exemplary embodiment, the mixer 50 includes a second disk portion 510 and an annular wall portion 520. The second disk portion 510 defines a central axis L and includes a third surface 511 and a fourth surface 512 that are opposite to each other. The annular wall portion 520 surrounds the periphery of the second disk portion 510 and protrudes from the third surface 511 and the fourth surface 512. When the flow divider 30 and the mixer 50 are assembled, the central axis L defined by the first disk portion 310 coincides with the central axis L defined by the second disk portion 510.

[0084] The mixer 50 includes a plurality of second water inlet holes 513 and a plurality of reflux holes 514. The plurality of second water inlet holes 513 are formed on the second disk portion 510 and penetrate the third surface 511 and the fourth surface 512. The plurality of second water inlet holes 513 are evenly arranged along the circumference of the second disk portion 510 with the central axis L as the center. The plurality of reflux holes 514 are formed on the second disk portion 510 and penetrate the third surface 511 and the fourth surface 512. The plurality of reflux holes 514 are evenly arranged along the circumference of the second disk portion 510 with the central axis L as the center.

[0085] like Figure 3 As shown, when the diverter 30 and the mixer 50 are assembled, the plurality of second water inlet holes 513 correspond to the plurality of first water inlet holes 313 one by one, and the flow area of ​​each second water inlet hole 513 is larger than the flow area of ​​the corresponding first water inlet hole 313. When water flows into the shower head and flows through the water inlet channel 101, the first water inlet hole 313 and the second water inlet hole 513 in sequence, since the flow area of ​​the second water inlet hole 513 is larger than the flow area of ​​the first water inlet hole 313, according to the Bernoulli principle, a certain negative pressure will be generated in the second water inlet hole 513, so that the outside air is sucked into the shower head from the inlet channel 314.

[0086] Please continue reading Figure 6 The third surface 511 of the mixer 50 has an annular groove 530, and the portion of the annular wall portion 520 protruding from the third surface 511 of the second disk portion 510 forms an accommodation space 560. When the flow splitter 30 and the mixer 50 are assembled, the first disk portion 310 of the flow splitter 30 is accommodated in the accommodation space 560, and at the same time, the second surface 312 of the first disk portion 310 is in contact with the third surface 511 of the second disk portion 510. Due to the presence of the annular groove 530, the above-mentioned first chamber 60 is formed between the flow splitter 30 and the mixer 50.

[0087] like Figure 3 As shown, the inlet flow channel 314, the multiple return holes 514, the multiple first water inlet holes 313 and the multiple second water inlet holes 513 are all connected to the first chamber 60, and the multiple return holes 514 are staggered with the multiple first water inlet holes 313. After being sucked in from the inlet flow channel 314, the outside air passes through the first chamber 60 and the second water inlet holes 513 in sequence, and forms a mixed water flow with a certain amount of bubbles with the water flow. After the mixed water flow enters the second chamber 80, a part of the mixed water flow will return to the first chamber 60 through the return holes 514, and then be sucked into the second water inlet holes 513, and the cycle repeats.

[0088] Since part of the mixed water flow that returns will fill the first chamber 60 during the reciprocating cycle, it will prevent the outside air from being sucked into the shower head, which plays a role in reducing the amount of air intake. As this part of the mixed water flow is sucked into the second water inlet hole 513 again, when the first chamber 60 is not filled with the mixed water flow, the outside air continues to be sucked in, thereby achieving the effect of automatically controlling the amount of outside air intake. At the same time, since the amount of outside air intake is effectively controlled, the bubbles in the mixed water flow with a certain amount of bubbles are smaller, and the shower head can produce bubble water with micro bubbles.

[0089] Please continue reading Figure 6 and Figure 7 In an example embodiment, the multiple reflow holes 514 of the mixer 50 are closer to the central axis L than the multiple second water inlet holes 513. In other words, the radius of the circle formed by the multiple reflow holes 514 evenly distributed along the circumference of the second disk portion 510 is smaller than the radius of the circle formed by the multiple second water inlet holes 513 evenly distributed along the circumference of the second disk portion 510.

[0090] Through this design, Figure 3 Taking the second water inlet hole 513 and the return hole 514 located on the left side of the central axis L as an example, the partially returned mixed water flow circulates through the return hole 514, the first chamber 60, the second water inlet hole 513 and the second chamber 80, and its circulation direction is counterclockwise, while the flow direction of the outside air entering the second water inlet hole 513 from the inlet flow channel 314 is just opposite to the circulation direction. Accordingly, the partially returned mixed water flow better prevents the outside air from being sucked into the shower head during the circulation process, and finally achieves the effect of automatically controlling the intake amount of the outside air.

[0091] like Figure 3 , Figure 4 and Figure 6 As shown, the shower head further includes a plurality of fasteners 40 for connecting the diverter 30 and the mixer 50. In one embodiment, the fasteners 40 may be screws.

[0092] The diverter 30 includes a plurality of through holes 315, and the mixer 50 includes a plurality of connecting posts 540. The plurality of connecting posts 540 protrude from the fourth surface 512 of the second disk portion 510 of the mixer 50 and extend toward the water outlet cover 90. The plurality of through holes 315 correspond to the plurality of connecting posts 540 one by one, and the plurality of fasteners 40 pass through the plurality of through holes 315 and are connected to the plurality of connecting posts 540 respectively.

[0093] In addition, one end of the plurality of connection posts 540 away from the diverter 30 is close to the filter assembly 70 to prevent the filter of the filter assembly 70 from wrinkling, thereby making the filter smoother.

[0094] Of course, in other embodiments, the splitter 30 and the mixer 50 may be connected by other suitable connection methods, which will not be described in detail here.

[0095] Please continue reading Figure 3 The water outlet cover 90 is detachably connected to the annular wall portion 520 of the mixer 50, for example, by a threaded connection, so that the water outlet cover 90 can be removed at any time to clean the shower head, for example, to clean the filter assembly 70. A sealing ring 20 is also provided between the water outlet cover 90 and the mixer 50 to prevent water from leaking from the connection between the two.

[0096] like Figure 1 and Figure 3 As shown, a second chamber 80 is formed between the water outlet cover 90 and the mixer 50, and the plurality of second water inlet holes 513 and the plurality of return holes 514 are all connected to the second chamber 80. The shower head further comprises a plurality of stacked filters, which are disposed in the second chamber 80.

[0097] After being sucked in, the outside air mixes with the water flow to form a water flow with bubbles, which flows through the second water inlet hole 513 and then flows into the second chamber 80. Part of the water flow will flow back to the first chamber 60 from the return hole 514, which will not be described in detail here. Another part of the air-water mixture passes through the filter assembly 70, and the larger bubbles are cut into tiny bubbles by the filter, so that the water flow finally flowing out of the water outlet cover 90 contains micro bubbles to produce bubble water with good effect.

[0098] like Figure 1 As shown, the plurality of filters include a plurality of first filters 710 and a plurality of second filters 720, and the plurality of first filters 710 and the plurality of second filters 720 are alternately stacked, and the mesh number of the first filter 710 is different from the mesh number of the second filter 720. For example, the first filter 710 may be a sparse-pore filter, and the second filter 720 may be a dense-pore filter. The plurality of first filters 710 and the plurality of second filters 720 form a filter assembly 70 with sparse and dense meshes alternately stacked, so as to achieve the best effect of cutting bubbles.

[0099] like Figure 4 and Figure 6 As shown, in one embodiment, the first disk portion 310 of the diverter 30 is provided with a positioning protrusion 330, and the mixer 50 is provided with a positioning notch 550 that cooperates with the positioning protrusion 330. When the diverter 30 and the mixer 50 are assembled, the two can be easily assembled through the cooperation of the positioning protrusion 330 and the positioning notch 550, so that the first water inlet hole 313 and the second water inlet hole 513 are quickly and conveniently aligned, thereby improving the assembly efficiency.

[0100] Of course, in other embodiments, the positioning protrusion 330 may also be provided on the mixer 50, and the positioning notch 550 may be provided on the diverter 30; or, the assembly positioning may be achieved through other suitable positioning structures, which are not listed here one by one.

[0101] Another exemplary embodiment of the bubble water generating device of the present invention may also be a bubble maker.

[0102] like Figure 8 and Fig. 9 As shown, Figure 8 is a side view of another exemplary embodiment of the bubble water generating device of the present invention, Fig. 9 2 is a cross-sectional view of another exemplary embodiment of the bubble water generating device of the present invention. In this embodiment, it is different from the above-mentioned embodiment of the shower head in that:

[0103] The bubbler includes a filter component 100, a diverter 30, a mixer 50, a filter assembly 70 and a water outlet cover 90. The water outlet cover 90 is buckled with the mixer 50 and the diverter 30, and a second chamber 80 is formed between the water outlet cover 90 and the mixer 50, and the filter assembly 70 is disposed in the second chamber 80. An inlet flow channel 314 is formed between the side wall of the water outlet cover 90 and the side wall of the diverter 30, and the inlet flow channel 314 is connected to the first chamber 60.

[0104] When water flows through the filter component 100, the first water inlet hole 313 and the second water inlet hole 513 in sequence, since the flow area of ​​the second water inlet hole 513 is larger than the flow area of ​​the first water inlet hole 313, according to the Bernoulli principle, a certain negative pressure will be generated in the second water inlet hole 513, so that the outside air is sucked into the bubbler from the inlet flow channel 314. The principle of generating microbubbles in the bubbler is basically the same as that of the above-mentioned shower implementation, and will not be repeated here.

[0105] Of course, in other embodiments, the intake flow passage may also be formed on the splitter or other suitable components / positions.

[0106] In summary, the advantages and beneficial effects of the bubble water generating device of the present invention are:

[0107] The water flows through the first water inlet hole 313 and the second water inlet hole 513 in sequence. Since the flow area of ​​the second water inlet hole 513 is larger than the flow area of ​​the first water inlet hole 313, according to Bernoulli's principle, a certain negative pressure will be generated in the second water inlet hole 513, so that the external air passes through the inlet flow channel 314 and the first chamber 60 in sequence and is sucked into the second water inlet hole 513, and forms a mixed water flow with the water flow with certain bubbles. After the mixed water flow enters the second chamber 80, a part of the mixed water flow will return to the first chamber 60 through the reflux hole 514, and then be sucked into the second water inlet hole 513, and the cycle will be repeated. Since part of the mixed water flow that returns will fill the first chamber 60 during the reciprocating cycle, it will prevent the outside air from being sucked into the bubble water generating device, thereby reducing the amount of air intake. As the part of the mixed water flow is sucked into the second water inlet hole 513 again, when the first chamber 60 is not filled with the mixed water flow, the outside air continues to be sucked in, thereby achieving the effect of automatically controlling the amount of outside air intake. At the same time, since the amount of outside air intake is effectively controlled, the bubbles in the mixed water flow with a certain amount of bubbles are smaller, and thus the bubble water generating device can generate bubble water with micro bubbles.
