[0041] The present application provides a release device 20 for releasing micro-nano bubbles, which can be used in devices capable of outputting water, such as shower, spray head, faucet and the like. For the convenience of description, the following is described by taking the shower as an example. The release device 20 is arranged on one side of the water outlet of the shower. The release device 20 has a water outlet surface facing the outside of the shower and a water inlet surface arranged opposite to the water outlet surface. When the water in the shower is output from the release device 20, the water enters the release device 20 from the water inlet surface and is output through the water outlet surface. The dissolved air in the water can form micro-nano bubbles, which are sprayed from the shower together with the water to form micro-nano bubble water. Figures 1 to 6 The drawings corresponding to the embodiments of the present application.

[0042] Please refer to Figure 1 In an embodiment, the release device 20 comprises:

[0043] The rectifier plate 21 is provided with at least two rectifier holes 211. The side surface of the rectifier plate 21 facing the inside of the shower forms the water inlet surface of the release device 20. The rectifier holes 211 are arranged in the form of holes with gradually reduced inner diameter from the water inlet surface to the water outlet surface. The number of the rectifier holes 211 can be multiple. The rectifier holes 211 are arranged at intervals on the rectifier plate 21 and form water flow channels.

[0044] The release plate 22 is arranged opposite to the rectifier plate 21. The release plate 22 is provided with at least two release holes 221, which are arranged one by one corresponding to the rectifier holes 211. The side surface of the release plate 22 facing the outside of the shower forms the water outlet surface of the release device 20. The number and position of the release holes 221 correspond to those of the rectifier holes 211, so that the water can enter the release holes 221 from the rectifier holes 211. The release holes 221 are arranged in the form of through holes with gradually increased diameter from the water inlet surface to the water outlet surface. The release holes 221 are arranged in the release plate 22 to form water flow channels.

[0045] A jet flow plate 23 is arranged between the flow regulation plate 21 and the release plate 22, and at least two jet flow holes 232 are arranged on the jet flow plate 23; the jet flow holes 232 on the jet flow plate 23 are used to communicate the flow regulation holes 211 and the release holes 221 to form a channel for the liquid in the flow regulation holes 211 to flow to the release holes 221. The flow regulation plate 21, the jet flow plate 23 and the release plate 22 are detachably connected, and when the release device 20 is detached from the shower head, the release plate 22 and the flow regulation plate 21 can be directly separated from each other.

[0046] Please refer to Figure 2 and Figure 3 Each of the flow regulation holes 211 is communicated with the corresponding release hole 221 through one of the jet flow holes 232. Because a large amount of air is usually dissolved in water, the air is in the form of large bubbles in water. When the water enters the tapering flow regulation holes 211, the water in the flow regulation holes 211 can form a mixed flow with the bubbles due to the pressure increase in the flow regulation holes 211. Because the release holes 221 are communicated with the flow regulation holes 211, when the liquid in the flow regulation holes 211 is output to the release holes 221 after the pressure increase in the flow regulation holes 211, the water flow is accelerated at the end of the flow regulation holes 211 close to the release holes 221. When the high-speed liquid flows to the release holes 221 through the tapering flow regulation holes 211, the large air bubbles dissolved in the liquid are cut and squeezed to form micro-nano bubbles with a diameter less than 50 μm, and then the micro-nano bubbles are output to the release holes 221 along with the water flow. The water flow entering the release holes 221 flows in the gradually expanding water flow channel. Because the space of the water flow channel is gradually expanded, the micro-nano bubbles in the water do not coagulate to form large bubbles, and then the micro-nano bubble water is output through the release holes 221.

[0047] The release device 20 can be directly installed on the shower head, and the water flow channel formed by the flow regulation holes 211, the jet flow holes 232 and the release holes 221 can be directly used as the water outlet channel of the shower head, so that the air flow is not mixed again to cause the micro-nano bubbles to coagulate to form large bubbles when the air flow is output from the shower head, and the micro-nano bubble water is output.

[0048] When the release device 20 is manufactured, a plurality of flow regulation holes 211 can be uniformly arranged on the flow regulation plate 21, a plurality of release holes 221 can be uniformly arranged on the release plate 22, and the number of the jet flow holes 232 corresponds to the number of the flow regulation holes 211, so that when the release device 20 is installed on the shower head, the water is uniformly output at the preset positions. The end of the flow regulation holes 211 and the release holes 221 close to the jet flow plate 23 can be micro-hole structures with a hole diameter of about 0.2-0.8 mm.

[0049] Due to the jet plate 23 and the arrangement between the straightener plate 21 and the release plate 22, the straightening hole 211 is arranged in a tapering manner, and the release hole 221 is arranged in a tapering manner, and the inner diameter of the one end of the jet hole 232 is relatively small, and when the micro-hole structure is adopted, the water flow channel is smaller, so that the straightening hole 211 and the release hole 221 are very inconvenient to clean. In the embodiment, the jet plate 23 is arranged between the release plate 22 and the straightener plate 21, and when cleaning is needed, the release device 20 can be disassembled to expose the small hole diameter end of the straightening hole 211 and the release hole 221, and then the cleaning can be directly and conveniently performed.

[0050] Due to the tapering arrangement of the straightening hole 211 and the tapering arrangement of the release hole 221, when processing, the small hole diameter end of the micro-hole arranged straightening hole 211 and release hole 221 is very difficult to process, and the processing precision is very limited, especially when the release plate 22 and the straightener plate 21 are arranged as an integral structure, the hole diameter of the connecting part of the release hole 221 and the straightening hole 211 is very small, which directly affects the processing precision. Therefore, in the embodiment, the release plate 22 and the straightener plate 21 can be processed respectively, the processing precision can be conveniently controlled, the processing of the release hole 221 and the straightening hole 211 is more controllable, and then the processing efficiency can be improved.

[0051] In an embodiment, the thickness of the straightener plate 21 is not less than 2mm and not more than 5mm; the straightener plate 21 can adopt 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm or 5mm, or any other value between 2 to 5mm.

[0052] In another embodiment, the thickness of the jet plate 23 is not less than 0.2mm and not more than 0.5mm; the thickness of the jet plate 23 can be 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm or 0.5mm, or any other value between 0.2 to 0.5mm. The thickness of the straightener plate 21 can adopt any value in the previous embodiment.

[0053] In still another embodiment, the thickness of the release plate 22 is not less than 5mm and not more than 20mm. The thickness of the release plate 22 can be 5mm, 8mm, 10mm, 13mm, 15mm, 17mm or 20mm, or any value between 5 to 20mm. The thickness of the straightener plate 21 and the jet plate 23 can be any value in the previous embodiment.

[0054] Please refer to Figure 3In an embodiment, the jet flow hole 232 has a smaller diameter than the smallest diameter of the rectifying hole 211 and the release hole 221. The jet flow plate 23 blocks the water flow between the rectifying plate 21 and the release plate 22, and forms a water flow channel with a smaller cross-sectional area. The water entering the rectifying hole 211 is gradually pressurized and mixed as it passes through the channel arranged in a tapering manner. Since the diameter of the jet flow hole 232 is smaller than the smallest diameter of the rectifying hole 211, the water flow is pressurized again as it passes through the jet flow hole 232. When the water flow passes through the jet flow hole 232, the large bubbles in the water flow are cut to form micro-nano bubbles smaller than 50 μm, thereby increasing the content of micro-nano bubbles in the micro-nano bubble water. Optionally, the jet flow hole 232 can be a micro-hole structure with a diameter of 0.2-0.5 mm. Since the machining difficulty of forming a gradually expanding hole or a gradually tapering hole increases when a micro-hole structure is used, by separately arranging the jet flow plate 23 between the rectifying plate 21 and the release plate 22, the jet flow hole 232 with a smaller diameter can be conveniently machined. By arranging the jet flow plate 23, the micro-nano bubbles in the water flow can be maintained as the water flow passes through the jet flow hole 232 on the jet flow plate 23. When the water flow passes through the release hole 221 arranged in a tapering manner, the stability of the micro-nano bubbles in the water flow is relatively higher, so that the content of micro-nano bubbles in the micro-nano bubble water remains in a relatively stable state.

[0055] Optionally, the jet flow plate 23 is a metal piece. By using a metal piece, the jet flow hole 232 can be conveniently formed on the jet flow plate 23. Since the diameter of the jet flow hole 232 is relatively small, using a metal piece to form the jet flow plate 23 can improve the strength of the jet flow plate 23, so that the jet flow plate 23 is not easily damaged when the pressurized water flow passes through it. Since the machining of a micro-hole structure on a metal piece is more convenient and the forming efficiency of the jet flow hole 232 is higher, the overall quality of the release device 20 can be improved.

[0056] The rectifying plate 21 and the release plate 22 can be made of a non-metal material. Since the small hole end of the rectifying hole 211 and the release hole 221 is transitioned by the jet flow hole 232 of the jet flow plate 23, the machining performance of the rectifying hole 211 and the release hole 221 can be improved, and the forming can be facilitated.

[0057] Please refer to Figure 1 , Figure 2 and Figure 3 , in order to facilitate positioning, in an embodiment, the jet flow plate 23 is provided with a positioning hole 231; the positioning hole 231 is a through hole passing through the jet flow plate 23. One of the rectifying plate 21 and the release plate 22 is provided with a positioning protrusion 212, and the other is provided with a positioning recess 222; the positioning protrusion 212 penetrates the positioning hole 231 and is embedded in the positioning recess 222.

[0058] With the positioning protrusion 212 arranged on the rectifier plate 21 and the positioning recess 222 arranged on the release plate 22 as an example, when the release device 20 needs to be assembled, the positioning protrusion 212 is inserted into the positioning hole 231, so that the positioning protrusion 212 partially extends out of the jet plate 23, and the part of the positioning protrusion 212 protruding from the side of the jet plate 23 away from the rectifier plate 21 is embedded in the positioning recess 222, so that the jet plate 23 is clamped between the rectifier plate 21 and the release plate 22, to limit the radial movement of the rectifier plate 21, the jet plate 23 and the release plate 22 along the jet hole 232. Alternatively, the positioning protrusion 212 can also be arranged on the release plate 22, and the positioning recess 222 is arranged on the rectifier plate 21. The positioning protrusion 212 and the positioning recess 222 can also be arranged on the rectifier plate 21, and the corresponding positioning protrusion 212 and the positioning recess 222 are arranged on the release plate 22, so that the release plate 22 and the rectifier plate 21 can limit each other.

[0059] Based on the above-mentioned release device 20, the application further provides an embodiment of a water outlet device.

[0060] Please refer to Figure 4 , the water outlet device comprises:

[0061] a main body 10, the main body 10 is formed with a water inlet 11 and a water outlet; and

[0062] The release device 20 is arranged at the water outlet, the rectifier plate 21 of the release device 20 is arranged in the main body 10, and the release plate 22 of the release device 20 is arranged towards the outside of the water outlet.

[0063] The water outlet device is taken as a shower as an example. The shower is internally formed with a water outlet cavity 13. Water enters the water outlet cavity 13 from the water inlet 11 and is output to the outside by the releaser 20. The releaser 20 is integrally installed on the shower. The straightening hole 211 of the straightening plate 21 communicates with the water outlet cavity 13. The straightening hole 211, the jet hole 232 and the release hole 221 are sequentially connected to form a water flow channel. The water flow channel serves as the water outlet channel of the shower without the need of separately arranging a water spraying hole on the shower. Before the water enters the shower from the water inlet 11, a large amount of air has been mixed in the water. In this embodiment, the releaser 20 is arranged as the water outlet component of the shower to realize the output of micro-nano bubble water without the need of separately arranging a water outlet hole of the shower. The micro-nano bubble water formed by the releaser 20 can be directly output. Alternatively, the releaser 20 is detachably connected with the main body 10 to facilitate the removal of the releaser 20 from the water outlet device for cleaning. The detachable connection mode can be screw connection, clamping, pin connection or other connection modes. When the releaser 20 is installed, a stop portion 12 can be arranged in the water outlet cavity 13 of the main body 10. The stop portion 12 is used to stop the water inlet surface side of the straightening plate 21 to limit the installation position of the releaser 20. The stop portion 12 can be a protrusion arranged on the inner wall of the main body 10. When the stop portion 12 abuts against the straightening plate 21, the contact position of the stop portion 12 and the straightening plate 21 is staggered with the straightening hole 211.

[0064] Due to the cooperation of the straightening plate 21, the jet plate 23 and the release plate 22, the air dissolved in the water entering the water outlet cavity 13 can be pressurized and mixed to form micro-nano bubble water with a large and stable micro-nano bubble content. The air inlet channel for supplementing air into the shower is not additionally arranged, thereby simplifying the structure of the shower and improving the utilization rate of the internal space of the shower. The water outlet device can further be provided with a purification module, such as a purification net or the like. The purification module can be arranged on the water inlet 11 side. The shower is taken as an example. The position of the shower connected with the water outlet hose is usually a detachable structure. The purification module can be installed at the connection position of the shower and the water outlet hose.

[0065] Please refer to Figure 4 In an embodiment, when the releaser 20 and the main body 10 are connected in the screw connection mode, the main body 10 is provided with an internal thread. The releaser 20 is at least partially screwed into the main body 10. The release plate 22 is threadedly connected with the main body 10. Since the straightening plate 21 is arranged towards the water outlet cavity 13 in the main body 10, when the release plate 22 is threadedly connected with the main body 10, the straightening plate 21 and the jet plate 23 are also located inside the main body 10.

[0066] The release plate 22 can be partially located in the main body 10 or completely screwed into the main body 10. In order to avoid water leakage at the connection between the release plate 22 and the main body 10, a sealing ring 30 is optionally arranged between the release plate 22 and the main body 10 to seal the connection between the release plate 22 and the main body 10.

[0067] Further optionally, the sealing ring 30 is arranged at one end of the release plate 22 away from the rectifier plate 21. When the release plate 22 is completely located in the main body 10, the sealing ring 30 can be located in the gap between the release plate 22 and the inner wall of the main body 10. When the release plate 22 is partially located in the main body 10, the outer peripheral edge of the one end of the release plate 22 away from the rectifier plate 21 can form a flange which abuts against the outer surface of the main body 10 to limit the maximum installation depth of the release device 20. The sealing ring 30 can be clamped in the gap between the flange and the main body 10. The flange cooperates with the stopper 12 in the main body 10 to define the installation position of the release device 20, thereby achieving the installation and fixation of the release device 20.

[0068] Please refer to Figure 5 and Figure 6 In another embodiment, the main body 10 is provided with a mounting seat 14, the mounting seat 14 is provided with an annular wall 15 which is arranged towards the outside of the water outlet of the main body 10; the mounting seat 14 can be provided with the stopper 12 as described in the foregoing embodiment to abut against the water inlet surface of the rectifier plate 21 and limit the release device 20. The main body 10 is externally provided with a fixing cover 16 which is detachably connected with the annular wall 15, the inner wall surface of one end of the fixing cover 16 away from the mounting seat 14 is provided with a limiting protrusion 17; the rectifier plate 21 is arranged on the inner side of the annular wall 15, the outer peripheral edge of the release plate 22 is provided with a protruding portion 223 which is clamped between the limiting protrusion 17 and the jet plate 23. Optionally, the fixing cover 16 entirely surrounds the outer periphery of the release device 20, one end of the fixing cover 16 is connected with the annular wall 15, the other end of the fixing cover 16 is bent towards the axial direction to form the limiting protrusion 17, the limiting protrusion 17 abuts against the protruding portion 223 to limit the protruding portion 223 on the side of the limiting protrusion 17 towards the mounting seat 14, thereby limiting the release plate 22, and the rectifier plate 21 and the jet plate 23 are both limited between the release plate 22 and the mounting seat 14. Optionally, a sealing ring 30 is arranged between the limiting protrusion 17 and the protruding portion 223 to prevent water leakage at the connection between the release device 20 and the main body 10.
