The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0042] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0043] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] like Figures 1 to 14 As shown, this utility model provides a microbubble generator 10, which includes a barrel body 1 and a cutting assembly 2. The barrel body 1 has an inner cavity 11, and the barrel body 1 is provided with an inlet 12 and an outlet 13 communicating with the inner cavity 11. The inlet 12 is used to inject gas and water, and the outlet 13 is used to discharge the bubble water out of the inner cavity 11. The cutting assembly 2 includes a cutting element 21, which is rotatably disposed in the inner cavity 11. The water flow entering through the inlet 12 can drive the cutting element 21 to rotate. The cutting element 21 is provided with a plurality of cutting holes.

[0046] Water and air are injected through the inlet 12. The water flow then drives the cutting element 21 to rotate in the inner cavity 11. During the rotation, the cutting element 21 can cut the water flow containing air bubbles, thereby reducing the number of air bubbles and forming a denser and softer microbubble water, thus improving the user experience.

[0047] like Figure 2 and Figure 3 As shown, in some embodiments, for ease of installation and maintenance, the barrel 1 includes a barrel body 14 and a barrel lid 15. The upper end of the barrel body 14 is open, and the barrel lid 15 can be connected to the barrel body 14 by means of, but not limited to, snap-fit, screw connection, etc., thereby sealing the opening. The inlet 12 and outlet 13 are both located on the barrel body 14. It is understood that a sealing ring 3 is sandwiched between the barrel lid 15 and the barrel body 14.

[0048] In order to prolong the time the water flows in the inner cavity 11, so that the water flow can be fully cut, the bubbles can be further split and reduced, and the number of bubbles can be further increased, in some embodiments, the inlet 12 and the outlet 13 are not coaxial. The inlet 12 and the outlet 13 can be located on the same plane, but the included angle between them can be set; or the inlet 12 and the outlet 13 can be located on different planes, so as to achieve the misalignment of the two.

[0049] like Figure 5 and Figure 6 As shown, the tank body 1 may also be provided with a first return water port 16 and a second return water port 17 communicating with the inner cavity 11. The first return water port 16 and the second return water port 17 are connected by a connecting pipe (not shown), so that when some of the bubble water in the inner cavity 11 is discharged from the outlet 13, some of the bubble water can flow back into the inner cavity 11 through the first return water port 16 and the second return water port 17, thereby further cutting the bubbles and reducing their size. In the current embodiment, the first return water port 16 and the second return water port 17 are also coaxial.

[0050] Specifically, the barrel body 14 is provided with an inlet pipe 18, an outlet pipe 19, and a return pipe 110. The first end of the inlet pipe 18 is connected to the barrel body 14, and the second end port of the inlet pipe 18 is the inlet port 12. The first end of the return pipe 110 is connected to the barrel body 14, and the second end port of the return pipe 110 is the second return port 17. In the current embodiment, the inlet pipe 18 and the return pipe 110 are located on the same side of the barrel body 14. The outlet pipe 19 includes a first pipe section and a second pipe section. The first end of the first pipe section is connected to the barrel body 14, and the second end port of the first pipe section is the outlet port 13. The first end of the second pipe section is connected to the first pipe section, and the second end port of the second pipe section is the first return port 16.

[0051] In some embodiments, the microbubble generator 10 may further include a water inlet head 4, which includes a first pipe 41 and a second pipe 42. One end of the first pipe 41 is connected to the inlet 12, and the other end of the first pipe 41 is used to connect to a water source. Furthermore, the first pipe 41 has a reduced diameter section, and the second pipe 42 is connected to the reduced diameter section and is used to connect to an air pump. Thus, a mixture of gas and water can be injected into the inlet 12 through the water inlet head 4; and when water is introduced into the first pipe 41, the water flow accelerates in the reduced diameter section, thereby creating a negative pressure. The second pipe 42, connected to the reduced diameter section, can draw in air entering the second pipe 42, reducing the problem of poor air intake and also reducing the power requirements of the air pump, saving costs.

[0052] like Figure 3 and Figure 7 As shown, in some embodiments, the cutting element 21 is a filter screen. Therefore, to enable the filter screen to rotate within the inner cavity 11, the cutting element 21 also includes a rotating shaft 22 and a fixing frame 23. The fixing frame 23 is fixed to the rotating shaft 22. Rotation holes are provided on the inner bottom walls of the lid 15 and the body 14. Insertion holes 25 are provided on the fixing frame 23. The rotating shaft 22 is inserted into the insertion holes 25, and both ends of the rotating shaft 22 protrude from the insertion holes 25, so that both ends of the rotating shaft 22 are respectively connected to the aforementioned rotation holes. The filter screen is fixed to the fixing frame 23, and the rotation of the fixing frame 23 drives the filter screen to rotate. For example, the filter screen has a mesh size of 200-400 mesh, which allows for better cutting of the water flow. Too small a mesh size will easily obstruct the water flow, while too large a mesh size will weaken the cutting effect.

[0053] like Figure 4 and Figure 8 As shown, during the rotation of the fixed frame 23, the water flow tends to diffuse outward. In some embodiments, the outer periphery of the fixed frame 23 is provided with several protrusions 24, which impact the peripheral water flow, breaking it up and causing the bubbles to further split and decrease in size, thus increasing the number of bubbles. To improve the breaking effect, at least some adjacent protrusions 24 can be staggered.

[0054] like Figure 3 and Figure 4As shown, in some embodiments, the filter screen adopts an annular filter screen. Based on this, the fixing frame 23 includes a top seat 231 and a base 232. The top seat 231 and / or the base 232 are provided with a plurality of connecting posts 234 distributed at intervals along their axial direction. The top seat 231 and the base 232 are connected by the connecting posts 234. The two axial ends of the filter screen are clamped between the base 232 and the top seat 231. Specifically, an annular groove 2312 is provided on the side of the base 232 and the top seat 231 facing each other. One axial end of the filter screen is embedded in the annular groove 2312 of the base 232, and the other axial end of the filter screen is embedded in the annular groove 2312 of the top seat 231. Both the base 232 and the top seat 231 are provided with connecting posts 234, which extend along the axial direction of the filter screen. At least a portion of the connecting posts 234 are provided with first fixing blocks 2313. The base 232 and / or the top seat 231 are provided with first fixing holes 2314, so that the first fixing holes 2314 and the first fixing blocks 2313 are provided in a one-to-one correspondence. When the base 232 and the top seat 231 clamp the filter screen, the first fixing blocks 2313 are engaged in the first fixing holes 2314, thereby fixing the base 232, the top seat 231, and the filter screen.

[0055] In the current embodiment, the connecting post 234 located on the top seat 231 and the connecting post 234 located on the base 232 are arranged in a one-to-one correspondence. The connecting post 234 located on the top seat 231 is located inside the connecting post 234 located on the base 232, and the orthographic projection of the connecting post 234 located on the top seat 231 onto the connecting post 234 located on the base 232 falls on the connecting post 234 located on the base 232, thereby minimizing obstruction of water flow and improving water flow efficiency. Based on this, the protrusion 24 is provided on the outside of the connecting post 234 located on the base 232.

[0056] In the current embodiment, both the top seat 231 and the base 232 are provided with insertion holes 25 for the rotating shaft 22 to pass through.

[0057] It should also be noted that the annular filter has a relatively large cutting surface, allowing water to pass through twice, thereby maximizing the ability to cut the water flow, minimizing the breakup of bubbles, and increasing the number of bubbles.

[0058] like Figures 7 to 9As shown, in some embodiments, the filter screen is plate-shaped, and the fixing frame 23 includes a frame base 235 and a frame cover 236. The frame base 235 and the frame cover 236 are also plate-shaped. The frame base 235 is provided with a groove 237, in which the filter screen is embedded. The frame cover 236 is detachably mounted on the frame base 235, thereby clamping the filter screen between the frame base 235 and the frame cover 236. Specifically, one of the frame base 235 and the frame cover 236 is provided with a second fixing block 2315, and the other is provided with a second fixing hole 2316, so that the second fixing block 2315 is engaged with the second fixing hole 2316 to fix the frame base 235 and the frame cover 236. In the current embodiment, the second fixing block 2315 is disposed on the frame cover 236, and the second fixing hole 2316 is formed on the side wall of the groove 237, so that the frame cover 236 is at least partially embedded in the groove 237. Thus, the protrusion 24 is disposed on the outer periphery of the frame cover 236. The insertion hole 25 is also disposed on the frame base 235 for the rotating shaft 22 to pass through, and the specific details will not be described further.

[0059] like Figure 8 and Figure 9 As shown, more specifically, both the frame base 235 and the frame cover 236 include a frame body and a reinforcing beam in the middle of the frame body. The reinforcing beam of the frame base 235 is the bottom wall of the groove 237, and the frame body of the frame base 235 is the side wall of the groove 237. In some embodiments, one of the reinforcing beams of the frame base 235 and the frame cover 236 is provided with a plug-in post 238, and the other is provided with a plug-in hole 239, so that the filter screen can pass through the plug-in post 238 and abut against the reinforcing beam to improve stability.

[0060] To improve cutting efficiency, in some embodiments, the frame base 235 may be provided with two grooves 237, with the openings of the two grooves 237 facing each other; that is, the frame base 235 has two reinforcing beams inside the frame, thereby forming two grooves 237 that are opposite to each other. The frame cover 236 is provided in a one-to-one correspondence with the grooves 237, so that at least one filter screen can be provided in each groove 237 to improve cutting efficiency.

[0061] like Figure 10As shown, in some embodiments, a groove 237 is provided, and the fixed frame 23 also includes an agitator 2310. The agitator 2310 is connected to the side of the frame base 235 opposite to the opening of the groove 237. The agitator 2310 is set at an angle to the frame base 235, and the agitator 2310 is provided with several through holes 2311, so that the water flow is further cut by the rotation of the agitator 2310. In the current embodiment, the agitator 2310 is set perpendicular to the frame base 235, so that the cross-section of the fixed frame 23 is T-shaped. It can be understood that the outer periphery of the agitator 2310 can also be provided with protrusions 24 to further improve the cutting efficiency. Exemplarily, the agitator 2310 can be an agitator plate with through holes 2311; of course, the agitator 2310 can also be a filter screen.

[0062] like Figure 12 As shown, this utility model also provides a water outlet pipe, which includes an inlet valve 20 and a microbubble generator 10 as described above. The inlet valve 20 is connected to the inlet port 12 so as to supply water to the inner cavity 11. Then, through the rotational cutting of the cutting member 21, the bubble water is broken up, thereby forming a denser and softer microbubble water, improving the user experience.

[0063] This utility model also provides a toilet that uses the aforementioned water outlet pipe. Since the water outlet pipe is installed on the toilet, it may also include common components such as a heater 50, a water distribution valve 60, and a vacuum breaker 30; for example:

[0064] like Figure 12 As shown, the water outlet pipeline includes a heater 50, a water distribution valve 60, a vacuum breaker 30, a water pump 40, a spray gun 70, and a microbubble generator 10. The water inlet of the vacuum breaker 30 is connected to the water outlet of the water distribution valve 60, the water inlet of the water pump 40 is connected to the water outlet of the vacuum breaker 30, the water inlet of the heater 50 is connected to the water outlet of the water pump 40, and the water inlet of the water distribution valve 60 is connected to the water outlet of the heater 50. The spray gun 70 has multiple outflow channels, and the water distribution valve 60 has multiple outflow ends. The water inlets of the multiple outflow channels of the spray gun 70 are connected to different outflow ends of the water distribution valve 60, so that water can be selectively supplied to different outflow channels of the spray gun 70 through the water distribution valve 60. For example, the spray gun 70 may include, but is not limited to, a self-cleaning channel and a cleaning channel, so that water washing is performed through the cleaning channel and self-cleaning is performed through the self-cleaning channel.

[0065] Depending on the specific needs, the microbubble generator 10 can be positioned between the water distribution valve 60 and the heater 50, allowing microbubble water to flow directly through the cleaning channel to form a microbubble water wash. Alternatively, a bubble nozzle 90 can be connected to one of the outlets of the water distribution valve 60, allowing for both regular water washing through the cleaning channel and microbubble water washing through the bubble nozzle 90.

[0066] Of course, such as Figure 14 As shown, the microbubble generator 10 can also be installed at one of the outlet ends of the water distribution valve 60. The spray gun 70 also has a microbubble channel, so that the outlet 13 of the microbubble generator 10 is connected to the microbubble channel of the spray gun 70, thereby forming ordinary water cleaning through the cleaning channel and microbubble water washing through the microbubble channel, improving the adaptability to the inner pipe range; or as... Figure 13 As shown, the microbubble generator 10 is installed at one of the outlet ends of the water distribution valve 60, and an additional bubble nozzle 90 is connected to the microbubble generator 10.

[0067] In addition, a ceramic lubricating tube 80 can be installed in the water outlet pipeline. The ceramic lubricating tube 80 is connected to one of the water outlet ends of the water distribution valve 60, so that ceramic lubrication operation can be performed.

[0068] It is understood that the above-mentioned water outlet pipe is only one type of connection, and in other alternative embodiments, the connection positions of each component can be changed according to different water outlet requirements.

[0069] Of course, the water outlet pipe can also be used on other devices that require aerated water, such as shower heads and faucets.

[0070] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
