[0027] For existing intelligent toilets, bubbles are formed through flow-through pores, the number of generated bubbles is small, and the bubbles are relatively large. In addition, the method of generating bubbles has high requirements for water pressure and is prone to blockage risks.

[0028] Based on the above problems, the present application proposes a microbubble generating device, a cleaning device and a smart toilet. By providing a bubble generating part to generate a large number of microbubbles, the above problems can be effectively solved.

[0029] The following will describe in detail a microbubble generating device, a cleaning device and a smart toilet provided by the present application with reference to the accompanying drawings and embodiments.

[0030] Among them, the microbubble generating device of the present application can be specifically applied to any reasonable device that needs to discharge water, such as a faucet, a shower head, a cleaning device of a smart toilet, etc. However, for the convenience of description, the following microbubble generating devices will be described by taking the application in the cleaning device of a smart toilet as an example.

[0031] The present application provides a microbubble generating device. Please refer to Figures 1 to 4 , Figure 1 which is a schematic structural diagram of an embodiment of the microbubble generating device of the present application; Figure 2 is Figure 1 a schematic structural diagram of an embodiment of the bubble generating part in the microbubble generating device; Figure 3 is Figure 2 a schematic cross-sectional structural diagram of the bubble generating part; Figure 4 is Figure 2 a schematic structural diagram of the bubble splitting device in the bubble generating part being a filtering device. In a specific embodiment, the microbubble generating device 100 includes a bubble generating part 10, and the bubble generating part 10 includes a water inlet section 121, a pipe main body section 122 and a water outlet section 123.

[0032] The water inlet section 121 has a first water inlet channel 1211, and a part of the first water inlet channel 1211 shrinks to form a second water inlet channel 1212. The pipe main body section 122, the pipe main body section 122 includes a pipe contraction section 1221, a pipe middle section 1222 and a pipe expansion section 1223 which are connected in sequence. Among them, the pipe contraction section 1221 is connected to the second water inlet channel 1212. The water outlet section 123, one end of the water outlet section 123 is connected to the pipe main body section 122, and the other end of the water outlet section 123 is formed with an expanded surface nozzle 1231. In this embodiment, the bubble generating part 10 further includes a bubble splitting device 124, the bubble splitting device 124 is arranged in the pipe main body section 122, and / or the bubble splitting device 124 is arranged in the water outlet section 123. In some other embodiments, the bubble generating part 10 may not be provided with the bubble splitting device 124. Specifically, the bubble generating part 10 is used to generate microbubbles in the mixed fluid of input air and water in the bubble generating part 10. Among them, the water inlet section 121 is the input end of the mixed fluid of the bubble generating part 10. In the water inlet section 121, the radial dimension of the first water inlet channel 1211 is larger than the radial dimension of the second water inlet channel 1212. The sudden change in the radial area of the flow channel causes water and air to collide before entering the second water inlet channel 1212, thereby generating a large number of bubbles and splitting the bubbles during the collision. After the mixed fluid flows through the water inlet section 121, it enters the pipe contraction section 1221 of the pipe main body section 122. The pipe contraction section 1221 is along the flow direction of the mixed fluid, and the radial dimension of the pipe gradually decreases. In this flow section, the air and water in the mixed fluid are continuously compressed, and the pressure of the mixed fluid becomes larger. Finally, the compressed mixed fluid is sprayed to the pipe expansion section 1223 through the pipe middle section 1222. At this place, the radial area of the flow channel changes suddenly again, and the radial dimension of the pipe expansion section 1223 continuously becomes larger. When the mixed liquid enters the expansion area after passing through the narrow part, the flow rate slows down. According to Bernoulli's theorem, when the flow rate slows down, the pressure increases. This sudden change in pressure can cause an imbalance between the internal pressure and the external pressure of the bubble, prompting the bubble to further break and refine into small bubbles. When the small bubbles flow through the bubble splitting device 124, the bubbles are further fragmented to form a microbubble mixed fluid between 10 and 50 microns. Finally, the mixed fluid is sprayed out through the expanded surface nozzle 1231 of the water outlet section 123. When the mixed liquid passes through the expanded surface nozzle 1231, the fluid area continuously expands, the flow rate slows down, and the pressure increases. The sudden change in pressure can cause the small bubbles to be refined into microbubbles again, and the water with microbubbles in a milk state is sprayed out from the expanded surface nozzle 1231.

[0033] Further, in this embodiment, the bubble splitting device 124 is a core with a non-straight flow channel. The non-self-flow channel is specifically a rotating flow channel, such that when the mixed fluid flows through the core, the bubbles can continuously impact and split in the non-straight flow channel to be further refined. In some other embodiments, the non-straight flow channel can also be a bent flow channel, a curved flow channel or other non-straight flow channels, which are not specifically limited herein. Additionally, in this embodiment, the number of the bubble splitting devices 124 is two. One bubble splitting device 124 is arranged at the tail end of the pipe expansion section 1223 of the pipe main body section 122, and the other bubble splitting device 124 is arranged in the water outlet section 123. In some other embodiments, the number of the bubble splitting devices 124 can also be one, three, four or other reasonable numbers, which are not specifically limited herein.

[0034] Different from the prior art, the present application provides a microbubble generating device 100. The microbubble generating device 100 causes the mixed fluid to impact and generate bubbles and the bubbles to break by the sudden change in the radial area of the flow channel at the connection between the first water inlet channel 1211 and the second water inlet channel 1212. Then, when the mixed fluid flows through the pipe contraction section 1221 and is ejected from the pipe middle section 1222 to flow in the pipe expansion section 1223, a sudden change in pressure occurs. The sudden change in pressure causes pressure imbalance, and the bubbles in the mixed fluid can be further broken into small bubbles. When the small bubbles flow through the bubble splitting device 124, the bubbles are further fragmented, and finally are ejected through the enlarged surface nozzle 1231 of the water outlet section 123. The change in pressure during the diffusion ejection further refines the small bubbles, and finally presents microbubbles in a milk state. The bubbles generated by the microbubble generating device 100 are smaller in size, and the formation of bubbles through the flow pores is avoided, making it not easy to have a blockage risk, and the flow resistance of the flow channel is smaller, and the requirement for water pressure is lower.

[0035] In this embodiment, the bubble generating part 10 further includes a suction tee 11. The microbubble generating device 100 further includes a water pump 20. The suction tee 11 includes a water inlet pipe 112, a mixing pipe 113, and an air inlet pipe 111. One end of the mixing pipe 113 is connected to the water inlet pipe 112, and one end of the mixing pipe 113 is also connected to the air inlet pipe 111. The water pump 20, and the mixing pipe 113 is connected to the water inlet section 121 through the water pump 20. Specifically, the suction tee 11 is used for the water pump 20 to pump water. When the water passes through the water inlet pipe 112 and the mixing pipe 113, according to Bernoulli's theorem, a negative pressure is formed in the air inlet pipe 111, and the change in pressure causes air to be inhaled through the air inlet pipe 111 and mix with the water. Further, in a preferred embodiment, the outflow end size of the water inlet pipe 112 gradually decreases. The inflow end size of the mixing pipe 113 gradually increases. The outflow end size of the air inlet pipe 111 gradually decreases. This structural design ensures that when the water pump 20 pumps water and the water flows out of the water inlet pipe 112 and into the mixing pipe 113, a jet flow is formed in the mixing pipe 113, making the flow rate of the water greater. The greater the flow rate, the smaller the pressure, and the better the negative pressure effect, thereby improving the air suction effect of the suction tee 11. Further, in a preferred embodiment, the water inlet pipe 112 and the mixing pipe 113 are arranged collinearly, and the included angle between the air inlet pipe 111 and the water inlet pipe 112 is an acute angle. The purpose of arranging the water inlet pipe 112 and the mixing pipe 113 collinearly is to enable the water to continuously accelerate when entering the mixing pipe 113, with a better jet flow effect, better forming a negative pressure to suck air, and the greater flow rate of the water is more likely to generate the Bernoulli effect to form a shear force to fully mix the air and water. Among them, it is preferred that the included angle between the air inlet pipe 111 and the water inlet pipe 112 is less than 35 degrees. For example, the included angle between the air inlet pipe 111 and the water inlet pipe 112 can be 30 degrees, 25 degrees, etc.

[0036] Further, in some embodiments, the microbubble generating device 100 further includes an air pump 30, and the inflow end of the air inlet pipe 111 is connected to the air pump 30. Specifically, setting the air pump 30 can make the air suction effect of the suction tee 11 better, so that the water and air can be fully mixed.

[0037] Further, the suction tee 11 is arranged on the bubble generating part 10. In this embodiment, the suction tee 11 and the bubble generating part 10 are integrally designed. In some other embodiments, the suction tee 11 and the bubble generating part 10 can also be detachably fixed. For example, the suction tee 11 can be detachably fixed on the bubble generating part 10 by means of a clamping structure, a screw structure, a pin structure, etc., without specific limitation.

[0038] Further, in this embodiment, the bubble splitting device 124 is a core with a non-straight flow channel. In some other embodiments. The bubble splitting device 124 can also be a filtering device. Please refer to Figure 4, the filtering device can specifically be a filter screen, a filter element, a honeycomb device, etc. Preferably, the filtering device is a filter screen with a high mesh count. When the mixed fluid flows through the filter screen with a high mesh count, the bubbles can be further divided, increasing the bubble concentration. In some other embodiments, multiple bubble splitting devices 124 can be arranged in the bubble generating section 10. Among them, some of the bubble splitting devices 124 are cores with non-straight flow channels, and some of the bubble splitting devices 124 are filtering devices.

[0039] Furthermore, the bubble splitting device 124 can be clamped and fixed inside the bubble generating section 10. Specifically, the bubble splitting device 124 can be fixed inside the bubble generating section 10 through an interference structure, a clamping structure, etc. Among them, the bubble splitting device 124 can be made by injection molding with plastics that are lightweight and have good stamping resistance. For example, the manufacturing materials of the bubble splitting device 124 can include one or more of ABS (acrylonitrile-butadiene-styrene terpolymer), PC (polycarbonate), PET (polyethylene terephthalate), etc., without specific limitation.

[0040] In this embodiment, the pipeline main section 122 further includes a flow stabilizing section 1224. One end of the flow stabilizing section 1224 is connected to the pipeline expansion section 1223, the other end of the flow stabilizing section 1224 is connected to the water outlet section 123, and the channel of the flow stabilizing section 1224 is cylindrical. Among them, the bubble splitting device 124 can specifically be arranged inside the flow stabilizing section 1224.

[0041] Different from the prior art, the present application provides a microbubble generating device 100. The microbubble generating device 100 causes the mixed fluid to collide and generate bubbles and the bubbles to break by the sudden change in the radial area of the flow channel at the connection of the first water inlet channel 1211 and the second water inlet channel 1212. Then, when the mixed fluid flows through the pipeline contraction section 1221 and is ejected from the pipeline middle section 1222 to flow in the pipeline expansion section 1223, a sudden change in pressure occurs. The sudden change in pressure causes pressure imbalance, and the bubbles in the mixed fluid can be further broken into small bubbles. When the small bubbles flow through the bubble splitting device 124, the bubbles are further fragmented, and finally, they are ejected through the enlarged surface nozzle 1231 of the water outlet section 123. The pressure change during the diffusion ejection further refines the small bubbles, and finally, microbubbles in a milk state are presented. The bubbles generated by the microbubble generating device 100 are smaller in size, and the formation of bubbles through flow pores is avoided, making it not easy to have a blockage risk, and the flow resistance of the flow channel is smaller, and the requirement for water pressure is lower.

[0042] Correspondingly, the present application also proposes a cleaning device. Please refer to Figure 5 , Figure 5This is a schematic structural diagram of an embodiment of the cleaning device of the present application. The cleaning device 200 includes a microbubble generating device 100, a distribution valve 300, and a cleaner 400. The microbubble generating device 100 is the microbubble generating device 100 of the above embodiment. The distribution valve 300 is connected to the microbubble generating device 100, and the distribution valve 300 is also connected to the cleaner 400. For the above cleaning device 200, the sprayed cleaning water flowers are in a milk state, and the water flowers include numerous microbubbles, providing a better touch for the user, and the microbubbles can also improve the cleaning effect.

[0043] In a preferred embodiment, a water outlet nozzle (not shown) is provided on the cleaner 400, and a filter screen with a high number is further provided on the water outlet nozzle. The filter screen with a high number is provided on the water outlet nozzle of the cleaner 400 to further increase the bubble concentration of the cleaning water flowers. Among them, the water outlet nozzle is detachably and fixedly arranged so that when the nozzle is blocked, the user can remove the nozzle for cleaning.

[0044] Correspondingly, the present application also proposes an intelligent toilet. The intelligent toilet includes the microbubble generating device described in the above embodiment, or the intelligent toilet includes the cleaning device described in the above embodiment.
