[0054] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0055] The inventor of the present invention has found in research that when hot water passes through a microbubble generator, the flow rate of the water flow will go through a process from acceleration to deceleration. During this process, a low-pressure area will be generated. Since the pressure in the low-pressure area is low, the solubility of air in water will also decrease. Therefore, air will precipitate from the water, and the precipitated air cannot be quickly discharged in the water outlet device, thereby forming tiny bubbles, which flow out with the water flow to form microbubble water.

[0056] The inventor of the present invention further discovered in the research that in order to allow air to be fully precipitated from the water to form effective microbubble water, the length of the microbubble flow channel of the microbubble generator needs to be as long as possible so that the water flow through the microbubble flow channel can last long enough. In the device for generating microbubble water in the prior art or related art, since the flow direction of water through the microbubble flow channel is the same as the flow direction of water out of the final cover, if the size of the microbubble flow channel is designed to be longer, the thickness of the device in the water flow direction will be thicker, affecting the appearance of the product and poor user experience.

[0057] Therefore, how to balance the two conflicting dimensions of the length of the microbubble flow channel and the thickness of the product is a problem that designers in this field need to solve.

[0058] Based on this, an embodiment of the present invention provides a water outlet device. By adopting a technical means of obliquely or vertically arranging the first water flow direction of the microbubble flow channel of the microbubble generator and the second water flow direction of the water outlet hole of the cover, the thickness of the spraying part is designed to be thinner on the basis of ensuring the size requirements of the microbubble flow channel, the product is more beautiful, and the user experience is improved.

[0059] The water outlet device provided in the embodiment of the present invention includes a body, a microbubble generator and a cover, the body includes a connecting portion and a spraying portion, the connecting portion can be connected to a water supply pipe, the spraying portion is connected to the connecting portion, and can spray out the liquid supplied from the water supply pipe. The microbubble generator is connected to the spraying portion, and the microbubble generator has a microbubble flow channel, and the liquid can flow in the microbubble flow channel along a first water flow direction and produce microbubble water. The cover is connected to the spraying portion, and the cover has a water outlet hole, and the water outlet hole can spray out microbubble water along a second water flow direction. Wherein, the second water flow direction is inclined or perpendicular to the first water flow direction.

[0060] In the water outlet device of the embodiment of the present invention, the liquid supplied from the water supply pipe flows through the connecting part and the spraying part in sequence, and flows into the microbubble flow channel of the microbubble generator. Microbubble water is generated in the microbubble flow channel, and finally the microbubble water is sprayed out from the water outlet hole of the face cover. The liquid flows along the first water flow direction when flowing through the microbubble flow channel, and the microbubble water is sprayed out from the water outlet hole along the second water flow direction. The second water flow direction is inclined or perpendicular to the first water flow direction. Therefore, when the length of the microbubble flow channel is constant, compared with the arrangement of the first water flow direction and the second water flow direction in the prior art or related art, the thickness of the water outlet device of the embodiment of the present invention along the second water flow direction will become smaller, and the spraying part will become thinner in the second water flow direction, making the overall appearance of the product more beautiful and exquisite.

[0061] The structure, connection relationship and working principle of each component in the water outlet device of the embodiment of the present invention are described in detail below with reference to the accompanying drawings.

[0062] like Figures 1 to 3 As shown, Figure 1 The diagram shows a schematic structural diagram of a water outlet device according to an embodiment of the present invention from one viewing angle. Figure 2 It is a schematic structural diagram of a water outlet device according to an embodiment of the present invention from another perspective. Figure 3 The exploded view of the water outlet device of one embodiment of the present invention is shown. The water outlet device of the embodiment of the present invention comprises a body 100, a microbubble generator 300 and a cover 500. The microbubble generator 300 is connected to the body 100 and can generate microbubble water. The cover 500 is connected to the body 100 and can spray the microbubble water.

[0063] It is worth mentioning that the "connection" in the present invention document is not limited to the direct connection between the first component and the second component, but can also be: a third component is provided between the first component and the second component, and the first component is indirectly connected to the second component through the third component. For example, in an embodiment of the present invention, the microbubble generator 300 is connected to the body 100, and the cover 500 is connected to the body 100, wherein the cover 500 can be directly connected to the body 100, and the cover 500 can also be directly connected to the microbubble generator 300 and indirectly connected to the body 100.

[0064] Of course, it is understandable that the water outlet device of the present invention can be a bathroom shower, a faucet, a kitchen nozzle, a car wash nozzle or other devices that need to outlet water.

[0065] Of course, it can also be understood that the liquid supplied from the water supply pipe can be hot water, medicine, soapy water or other liquids.

[0066] like Figures 1 to 3 As shown, the body 100 of the embodiment of the present invention includes a connection portion 120, a handle portion 140 and a spray portion 160, wherein the connection portion 120 is provided at one end of the handle portion 140, and the spray portion 160 is provided at the other end of the handle portion 140. The connection portion 120 can be connected to a water supply pipe, and the liquid supplied from the water supply pipe flows through the connection portion 120, the handle portion 140 and the spray portion 160 in sequence. The spray portion 160 has an installation space 161, and the installation space 161 is used for installing the microbubble generator 300 therein.

[0067] like Figure 3 , Figure 6 and Figure 7 As shown, Figure 6 FIG. 1 is a schematic diagram of the structure of a micro-bubble generator 300 according to an embodiment of the present invention. Figure 7 It shows Figure 6The microbubble generator 300 of the embodiment of the present invention includes a base portion 320, a protrusion 340 and a side stop 360. The base portion 320 may be substantially disc-shaped, the protrusion 340 is disposed on one side of the base portion 320, and the microbubble flow channel 341 is disposed on the protrusion 340. The side stop 360 may be disposed on the outer periphery of the base portion 320.

[0068] Of course, it is understandable that the above-mentioned base portion 320 may not be a complete disc shape. For example, the base portion 320 of this embodiment also has a notch 321, and the notch 321 is used to set other parts of the water supply device therein to avoid interference between the base portion 320 and other parts.

[0069] In addition, it is understandable that the shape of the base portion 320 of the present invention is not limited to a disc shape, and it can also be other shapes as long as it can be compatible with the shape of the spray portion 160, which will not be listed here one by one.

[0070] When the base portion 320 is disc-shaped, the base portion 320 defines an axial direction Q, a radial direction S, and a radial plane P perpendicular to the axial direction Q. The axial direction Q and the radial direction S are perpendicular to each other.

[0071] like Figure 3 As shown, the face cover 500 includes a cover portion 520 and a side portion 540, the side portion 540 is arranged at the outer periphery of the cover portion 520, and the cover portion 520 is provided with a plurality of water outlet holes 521, and the water outlet holes 521 can spray microbubble water along the second water flow direction D2. The plurality of water outlet holes 521 can be evenly arranged on the cover portion 520 in a radial shape. Since the outer periphery of the cover portion 520 has a larger diameter than the inner periphery, the number of water outlet holes 521 on the outer periphery of the cover portion 520 is greater than the number of water outlet holes 521 on the inner periphery.

[0072] When the face cover 500 is connected to the spraying part 160 of the body 100, the side portion 540 can be connected to the spraying part 160 and arranged adjacent to a water outlet of the microbubble flow channel 341. The side portion 540 can buffer the microbubble water flowing out from the water outlet, so that the microbubble flow channel 341 can stably generate microbubbles. In the prior art or related art, the arrangement mode in which the first water flow direction is the same as the second water flow direction is adopted, and it is often necessary to provide a baffle near the water outlet of the microbubble flow channel, and the baffle plays the role of buffering the microbubble water. In the embodiment of the present invention, the microbubble water can directly collide with the side portion 540 of the face cover 500 after being ejected from the water outlet, so as to play the role of buffering the microbubble water without the need to provide an additional baffle.

[0073] Of course, it is understandable that the side baffle 360 ​​of the micro-bubble generator 300 can also play a role in buffering the water flow. The side baffle 360 ​​can play a role in buffering the micro-bubble water together with the side portion 540 of the cover 500, or the side baffle 360 ​​can play a role in buffering the micro-bubble water alone.

[0074] In one embodiment, the second water flow direction D2 may be parallel to the axial direction Q. When the second water flow direction D2 is parallel to the axial direction Q, as shown in FIG. Figure 2 As shown, the thickness T of the spraying portion 160 is the size of the spraying portion 160 along the second water flow direction D2.

[0075] like Figure 6 and Figure 7 As shown, there are two protrusions 340, which are arranged on the same side of the base 320 and are centrally symmetrically arranged with respect to the center point of the base 320. Each protrusion 340 is provided with four microbubble flow channels 341, and along the first water flow direction D1, each microbubble flow channel 341 includes a first flow channel 3411 and a second flow channel 3412 in sequence, wherein the flow channel cross-sectional area of ​​the first flow channel 3411 is smaller than the flow channel cross-sectional area of ​​the second flow channel 3412, so that the inner wall of the microbubble flow channel 341 forms a step shape. When the water flows through the first flow channel 3411 with a smaller flow channel cross-sectional area, the water flow velocity increases; when the water flows through the second flow channel 3412 with a larger flow channel cross-sectional area, the water flow velocity decreases.

[0076] like Figure 6 As shown, the base portion 320 is roughly disc-shaped and defines an axial direction Q, a radial direction S, and a radial plane P perpendicular to the axial direction Q. The first water flow direction D1 is parallel to the radial plane P, and there is an angle β between the first water flow direction D1 and the radial direction S. Through such a design, since the extension direction (first water flow direction D1) of the microbubble flow channel 341 is not along the radial direction S, but is inclined relative to the radial direction S, the size of the base portion 320 along the radial direction S can be reduced as much as possible when the length of the microbubble flow channel 341 is constant.

[0077] Combined with the above-mentioned design that the first water flow direction D1 and the second water flow direction D2 are perpendicular to each other, and the first water flow direction D1 is parallel to the radial plane P and has an angle with the radial direction S, while ensuring the length of the microbubble flow channel 341, the size of the spraying portion 160 along the axial direction Q and the radial direction S can be reduced as much as possible, and finally a spraying portion 160 with a smaller overall size is designed.

[0078] Of course, it is understandable that the microbubble flow channel 341 may also be trumpet-shaped. Specifically, the microbubble flow channel 341 has a water inlet end and a water outlet end, and the flow channel cross-sectional area of ​​the microbubble flow channel 341 gradually increases from the water inlet end to the water outlet end.

[0079] In addition, it can be understood that the present invention does not specifically limit the number of the microbubble flow channels 341 , and those skilled in the art can increase or decrease the number of the microbubble flow channels 341 according to the water output.

[0080] like Figure 4 and Figure 5 As shown, Figure 4 It shows Figure 1 The cross-sectional view along the section line AA, Figure 5 It shows Figure 1 A cross-sectional view along section line BB. Figure 4 and Figure 5 As shown by the middle arrow, the first water flow direction D1 in the microbubble flow channel 341 flows from the inner periphery to the outer periphery of the microbubble generator 300 , that is, the generated microbubble water first reaches the outer periphery of the cover 500 .

[0081] Below Figure 8 Taking the illustrated embodiment as an example, the water flow direction in the water outlet device is described in detail. Figure 8 FIG. 2 shows a cross-sectional view of a water outlet device according to an embodiment of the present invention, in which the first water flow direction D1 is perpendicular to the second water flow direction D2. Figure 8 As shown, the first water flow direction D1 is substantially perpendicular to the second water flow direction D2, and the first water flow direction D1 in the microbubble flow channel 341 flows from the inner periphery of the microbubble generator 300 to the outer periphery until it flows to the vicinity of the outer periphery of the face cover 500 and is blocked and buffered by the side portion 540. Afterwards, a portion of the microbubble water is ejected from the water outlet 521 disposed near the outer periphery of the face cover 500, and another portion of the microbubble water flows along the gap 600 between the microbubble generator 300 and the face cover 500 toward the inner periphery of the face cover 500, and is gradually ejected from the water outlet 521 during the inward flow.

[0082] Since the plurality of water outlet holes 521 are evenly arranged on the cover 500 in a radial shape, the outer periphery of the cover 500 has a larger diameter than the inner periphery, so that the number of water outlet holes 521 near the outer periphery of the cover 500 is greater than the number of water outlet holes 521 near the inner periphery. Therefore, most of the generated microbubble water can be ejected from the outer periphery of the cover 500 with a larger number of water outlet holes 521, and a small part of the microbubble water is ejected from the inner periphery of the smaller number of water outlet holes 521. Compared with the solution in the prior art or related art in which the microbubble water is mostly concentrated on the inner periphery of the cover 500, the water outlet method of the embodiment of the present invention makes the water outlet from the inner and outer peripheries of the cover 500 more uniform.

[0083] Of course, it is understandable that the first water flow direction D1 and the second water flow direction D2 can also be adopted as follows: Fig. 9 The embodiment shown is arranged in this manner. Fig. 9 FIG. 2 shows a cross-sectional view of a water outlet device according to an embodiment of the present invention, in which a first water flow direction D1 and a second water flow direction D2 form an acute angle. Fig. 9 As shown, there is an acute angle α1 between the first water flow direction D1 and the second water flow direction D2. The acute angle may be greater than or equal to 45 degrees and less than 90 degrees. Furthermore, the acute angle may be greater than or equal to 80 degrees and less than 90 degrees, for example, 81 degrees, 82 degrees, 83 degrees, 84 degrees, 85 degrees, 86 degrees, 87 degrees, 88 degrees, and 89 degrees.

[0084] Of course, it is understandable that Fig.10 As shown, Fig.10 The cross-sectional view of a water outlet device according to an embodiment of the present invention is shown, in which an obtuse angle is formed between the first water flow direction D1 and the second water flow direction D2. An obtuse angle α2 is formed between the first water flow direction D1 and the second water flow direction D2, and the obtuse angle may be greater than 90 degrees and less than or equal to 120 degrees. Further, the obtuse angle may be greater than 90 degrees and less than or equal to 100 degrees, such as 91 degrees, 92 degrees, 93 degrees, 94 degrees, 95 degrees, 96 degrees, 97 degrees, 98 degrees, and 99 degrees.

[0085] In summary, the advantages and beneficial effects of the water outlet device of the embodiment of the present invention are:

[0086] In the water outlet device of the embodiment of the present invention, the liquid supplied from the water supply pipe flows through the connecting part 120 and the spraying part 160 in sequence, and flows into the microbubble flow channel 341 of the microbubble generator 300. Microbubble water is generated in the microbubble flow channel 341, and finally the microbubble water is sprayed out from the water outlet hole 521 of the cover 500. The liquid flows along the first water flow direction D1 in the process of flowing through the microbubble flow channel 341, and the microbubble water is sprayed out from the water outlet hole 521 along the second water flow direction D2. The second water flow direction D2 is inclined or perpendicular to the first water flow direction D1. Therefore, when the length of the microbubble flow channel 341 is constant, compared with the arrangement mode in which the first water flow direction and the second water flow direction are the same in the prior art or related art, the thickness T of the water outlet device of the embodiment of the present invention along the second water flow direction D2 will be reduced, and the spraying part 160 will be thinner in the second water flow direction D2, so that the overall appearance of the product is more beautiful and delicate.
