[0041] Reference Figure 1-6 A bubbler, comprising:

[0042] The fixing component has a first water inlet 110 and a water inlet cavity 210 communicating with the first water inlet 110. The bottom of the water inlet cavity 210 is provided with a plurality of spray holes.

[0043] The movable component is rotatably connected to the fixed component. The movable component has a water-air mixing chamber 410, which is located below the water inlet chamber 210. The spray nozzle is connected to the water-air mixing chamber 410. The bottom wall of the water-air mixing chamber 410 is provided with several water outlets 431. The inner peripheral wall of the water-air mixing chamber 410 is evenly provided with several air intakes 421 along the circumference. The air intakes 421 are connected to the outside air. The high-speed water flow from the spray nozzle will form a negative pressure in the water-air mixing chamber 410, causing the air intakes 421 to draw in air, thereby achieving the effect of water-air mixing.

[0044] The filter screen 600 is located inside the water-air mixing chamber 410. The filter screen 600 can improve the uniformity of air bubbles.

[0045] The cleaning plate 700 is located inside the water-air mixing chamber 410, and the filter screen 600 is located below the cleaning plate 700. The cleaning plate 700 is equipped with a brush 710, which contacts the filter screen 600.

[0046] The filter screen 600 is fixedly connected to the movable component, and the cleaning plate 700 is fixedly connected to the fixed component; or, the cleaning plate 700 is fixedly connected to the movable component, and the filter screen 600 is fixedly connected to the fixed component. In this invention, it is preferable that the filter screen 600 is fixedly connected to the movable component. When the movable component rotates, the filter screen 600 rotates actively with the movable component, and the brush 710 passively rubs against the filter screen 600 in all directions, resulting in high structural stability.

[0047] In some embodiments of the present invention, the fixed component further includes a second water inlet 120 and a water outlet channel 240. The water outlet channel 240 is coaxial with the rotation axis of the movable component. The upper end of the water outlet channel 240 communicates with the second water inlet 120, and the lower end penetrates the bottom wall of the water-air mixing chamber 410. The filter screen 600 is fixedly connected to the inner peripheral wall of the water-air mixing chamber 410, and the cleaning plate 700 is fixedly connected to the outer peripheral wall of the water outlet channel 240. Alternatively, the cleaning plate 700 is fixedly connected to the inner peripheral wall of the water-air mixing chamber 410, and the filter screen 600 is fixedly connected to the outer peripheral wall of the water outlet channel 240. The first water inlet 110 is for tap water, and the second water inlet 120 is for purified water. Tap water flows out through the water outlet hole 431, and purified water flows out through the water outlet channel 240. The water outlet channel 240 and the water-air mixing chamber 410 are independent of each other, ensuring that the purified water is not contaminated and is safer to drink. The water outlet channel 240 is located at the center of the aerator and is concentrically distributed with the water-air mixing chamber 410. The water outlet channel 240 is coaxial with the rotation axis of the movable component, so the rotation of the movable component will not affect the water outlet channel 240. The water outlet channel 240 penetrates the water-air mixing chamber 410. The filter screen 600 or cleaning plate 700 can be connected to the outer peripheral wall of the water outlet channel 240, providing a fixed base for the filter screen 600 or cleaning plate 700. This invention cleverly integrates the brush 710 and the water outlet channel 240 within the aerator, achieving both the aerator's self-cleaning function and the pure water dispensing function. These two functions do not interfere with each other, improving the user experience.

[0048] In some embodiments of the present invention, the fixing component includes a water distribution body 100, a jet body 200, and a locking ring 300. The water distribution body 100 is connected to the jet body 200 to form a water inlet chamber 210 and a water outlet channel 240. A first water inlet 110 and a second water inlet 120 are provided on the top wall of the water distribution body 100. Spray holes are provided on the jet body 200. The locking ring 300 is annular. The water distribution body 100 is embedded in the locking ring 300. The inner or outer peripheral wall of the locking ring 300 is provided with threads for connecting with an external water outlet body. Specifically, the water distribution body 100 is composed of a first outer annular wall 130, a first inner annular wall 140 and a top wall. The first inner annular wall 140 is located inside the first outer annular wall 130. The jet body 200 is composed of a second outer annular wall 250, a second inner annular wall 260 and a bottom wall. The second inner annular wall 260 is located inside the second outer annular wall 250. The first inner annular wall 140 and the second inner annular wall 260 are sealed and fitted together to form a water outlet channel 240. The first outer annular wall 130 and the second outer annular wall 250 are threaded together to form a water inlet cavity 210. Preferably, the outer peripheral wall of the second inner annular wall 260 is provided with positioning protrusions 261, and the center of the cleaning plate 700 has a through hole 720. The wall of the through hole 720 is provided with a positioning groove 721. The second inner annular wall 260 is inserted into the through hole 720, and the positioning protrusions 261 cooperate with the positioning groove 721 to achieve circumferential fixation of the cleaning plate 700 and the spray body 200. At the same time, the top edge of the positioning groove 721 abuts against the bottom wall of the spray body 200 to ensure that the brush 710 always abuts against the filter screen 600. The above structure of the fixing component is easy to assemble and has low mold processing difficulty.

[0049] In some embodiments of the present invention, the movable component includes a bottom shell 400 and a rotating outer shell 500. The rotating outer shell 500 is annular, and the bottom shell 400 is located inside the rotating outer shell 500. The bottom shell 400 has a first sidewall 420 and a water outlet panel 430. The first sidewall 420 and the water outlet panel 430 form a water-air mixing chamber 410. An air intake 421 is provided on the first sidewall 420. The first sidewall 420 is provided with a plurality of ribs 422 along its circumference. An air intake groove 423 is formed between two adjacent ribs 422. The air intake 421 is located in the air intake groove 423. The ribs 422 are press-fitted with the inner circumferential wall of the rotating outer shell 500. A water outlet 431 is provided on the water outlet panel 430. The rotating outer shell 500 is rotatably connected to the fixed component. The air intake groove 423 communicates with the outside air through the fit gap between the bottom shell 400 and the rotating outer shell 500. Figure 5As shown in the figure, the dashed arrows indicate the airflow direction. Furthermore, the lower outer peripheral wall of the locking ring 300 has a raised ring 310, and the upper inner peripheral wall of the rotating housing 500 has a groove 510. The raised ring 310 and the groove 510 cooperate to achieve a rotational connection between the rotating housing 500 and the locking ring 300. Furthermore, the water outlet holes 431 on the water outlet panel 430 are honeycomb-shaped, maximizing the opening rate and balancing the flow resistance and negative pressure inside the aerator, maintaining the uniformity of the aerated water and ensuring a full and smooth water output from the aerator.

[0050] In some embodiments of the present invention, the fixing member includes a jet body 200, a water inlet cavity 210 formed in the jet body 200, a flange 440 is provided circumferentially on the inner side of the first sidewall 420, an air intake 421 is located below the flange 440, the flange 440 and the first sidewall 420 above it are connected by an arc to form a concave arc-shaped straightening section 441, the flange 440 is aligned with the bottom wall of the jet body 200 in the horizontal direction, and a water passage gap is left between the flange 440 and the bottom wall of the jet body 200, the spray hole includes a vertical spray hole 220 and a side spray hole 230, the vertical spray hole 220 is opened on the bottom wall of the jet body 200, the water outlet direction of the vertical spray hole 220 is downward, the side spray hole 230 is opened on the second sidewall of the jet body 200 and is evenly distributed along the circumference of the jet body 200, the water outlet direction of the side spray hole 230 is towards the straightening section 441. The rectifying section 441 has a concave arc-shaped structure, which allows the fluid pressure ejected from the side nozzles 230 to transition evenly to the next stage, while simultaneously enabling the lower air intake 421 to draw in air evenly, thus solving the noise problem caused by air pressure oscillations during air intake. Furthermore, the area of ​​a single side nozzle 230 is larger than that of a single vertical nozzle 220. The larger area of ​​the side nozzles 230 results in a larger water flow rate under the same water pressure, primarily creating negative pressure in the water-air mixing chamber 410 and improving air intake efficiency. The smaller area of ​​the vertical nozzles 220 mainly serves to supplement air intake, balancing internal air pressure, promoting fluid filling, and preventing hollow areas within the fluid.

[0051] In some embodiments of the present invention, a ring of inner wall surface at the lower end of the first sidewall 420 slopes inward from top to bottom to form a contraction section 450, and the bottom of the contraction section 450 is lower than the water outlet panel 430. The contraction section 450 can reduce splashing at the edge of the bubble water and guide the fluid to gather in the middle, preventing the bubble water from having hollow parts.

[0052] In some embodiments of the present invention, a water inlet body 800 is also included. The water inlet body 800 is located above the water distribution body 100 and is fixedly connected to the water distribution body 100. The water inlet body 800 has a first water inlet interface 810 and a second water inlet interface 820 for connecting to external pipe fittings. The first water inlet interface 810 is connected to the first water inlet 110, and the second water inlet interface 820 is connected to the second water inlet 120.

[0053] In some embodiments of the present invention, the cleaning plate 700 includes a disc 730 and a brush 710 fixedly connected to the disc 730. The brush 710 is located between the disc 730 and the filter screen 600. The disc 730 has a plurality of flow holes 731, and the brush 710 has at least one layer of barbs, each layer of barbs having a plurality of barbs 711 arranged circumferentially. Water flows from the water inlet chamber into the water-air mixing chamber at high speed through the spray hole. The barbs 711 vibrate slightly under the high-speed impact of the water flow. The vibration of the barbs 711 can reduce the phenomenon of bubble coalescence to a certain extent. The barbs 711 enhance the turbulence in the water-air mixing chamber, increase the bubble dispersion, make the bubble particles smaller and more evenly distributed, improve the water-air mixing efficiency, and make the bubbles last longer. Furthermore, the flow passage 731 and the vertical nozzle 220 are arranged alternately. After the water flows out of the vertical nozzle 220 at high speed, it first hits the solid part of the disc 730, and then flows from the flow passage 731 to the brush 710, which enhances the turbulence in the water-air mixing chamber 410 and improves the air-water mixing efficiency.

[0054] In some embodiments of the present invention, the barb assembly has two or more layers, with the barbs 711 of adjacent layers staggered in the vertical direction. "Two or more layers" includes two layers in total. These two or more layers of barbs, through multi-stage interception in three-dimensional space, cause the water flow to undergo multiple turbulence superpositions in the vertical direction, resulting in higher foaming efficiency. Furthermore, the barb assembly closest to the filter screen 600 contacts the filter screen 600, increasing the contact area between the brush 710 and the filter screen 600. During cleaning, the faucet is turned on, and the movable component is rotated while water flows out. The brush 710 rubs against the filter screen 600, causing the scale adhering to the filter screen 600 to fall off. The fallen scale is carried by the water flow in the water-air mixing chamber 410 to the water outlet 431 and discharged from the water outlet 431, achieving the effect of cleaning the filter screen. It should be noted that, firstly, even if the aerator has not been cleaned for a long time and scale has formed flakes on the filter screen 600, the combined action of high-speed water flow and friction with the brush 710 can break the scale into small particles. These small particles can pass through the filter screen smoothly, and since the aperture of the water outlet is much larger than that of the filter screen, the detached scale will not clog the water outlet. Secondly, the barbs 711 on the brush 710 abut against the surface of the filter screen 600, preventing calcium carbonate (scale) from precipitating and forming flakes. The unattached calcium carbonate precipitate is brittle and has weak intercrystalline bonding, so it can be broken by slight external force. Furthermore, since the brush 710 is made of elastic material, its barbs 711 will vibrate slightly under the high-speed impact of the water flow, preventing scale from adhering to the brush 710. The brush 710 can also be made of a scale-resistant material, giving it anti-scaling properties.

[0055] In some embodiments of the present invention, the filter screen 600 is located below the brush 710, and the barbs 711 are arranged horizontally or at an angle. When the barbs 711 are arranged at an angle, the barbs 711 gradually slope downward from their root to their tip. Compared to the barbs 711 being inclined upward, the barbs 711 being inclined downward can follow the direction of water flow, resulting in less resistance, less flow loss, and a larger amplitude.

[0056] Reference Figure 7-11 A water outlet device includes the aforementioned aerator, a first connecting pipe 900, a second connecting pipe 1000, and an integrated valve body 1100. The integrated valve body 1100 forms a main water passage 1110, a first valve core cavity 1120, a second valve core cavity 1130, and a first water outlet passage 1140.

The second end of 40 is connected to the main water passage 1110. A check valve 1141 is provided in the first outlet water passage 1140 to prevent water from flowing from the second end of the first outlet water passage 1140 to the first end. A reversing valve core 1400 is installed in the second valve core cavity 1130. The reversing valve core 1400 is a two-position four-way valve with a first inlet 1410, a second inlet 1420, a first outlet 1430 and a second outlet 1440.

The connection between the inlet and outlet is controlled by the rotating disk 1450 of the reversing valve core 1400. The rotating disk 1450 is provided with two water distribution holes 1451. There is a water passage space between the rotating disk 1450 and the valve body of the reversing valve core 1400. The two water distribution holes 1451 are connected through the water passage space. Rotating the valve stem 1460 of the reversing valve core 1400 can drive the rotating disk 1450 to rotate. When the reversing valve core 1400 is in the closed position, the two water distribution holes 1451 are not connected to either the inlet or the outlet. When the reversing valve core 1400 is in the initial filtration position, the two water distribution holes 1451 are connected to the first inlet 1410 and the first outlet 1430 respectively. When the reversing valve core 1400 is in the pure water position, the two water distribution holes 1451 are connected to the second inlet 1420 and the second outlet 1440 respectively.

[0057] The integrated valve body 1100 of this invention integrates three water outlet functions: hot and cold water, pre-filtered water, and purified water. The hot and cold water function is used for cleaning various kitchen utensils. The pre-filtered water refers to water that has undergone initial filtration to remove sediment and rust, and is mainly used for washing vegetables, fruits, and rinsing rice. The purified water is for daily drinking water. These functions are independently controlled by two valve cores: a reversing valve core 1400 controls the outlet and shut-off of pre-filtered and purified water, and a hot and cold valve core 1121 controls the outlet and shut-off of hot and cold water. Specifically, the hot and cold water, after being regulated by the hot and cold valve core 1121, enters the main water circuit 1110, and from the outlet of the main water circuit 1110, sequentially enters the first connecting pipe 900 and the aerator to form aerated water. The first inlet 1410 of the reversing valve core 1400 is connected to the primary water filter pipe 1500, and the second inlet 1420 is connected to the purified water pipe 1600. When the reversing valve core 1400 is switched to the primary water filter position, the primary water filter enters the reversing valve core 1400 and enters the first water outlet 1140 from the first outlet 1430, pushing the check valve 1141 to open. The primary water filter enters the main water circuit 1110 and then enters the first connecting pipe 900 and the aerator from the outlet of the main water circuit 1110. The hot and cold water and the primary water filter share the first connecting pipe 900. When the primary water filter stops entering, the check valve 1141 closes the first water outlet 1140 under the action of the spring, which can prevent the hot and cold water in the main water circuit 1110 from flowing back into the water purifier. When the reversing valve core 1400 is switched to the pure water setting, pure water enters the reversing valve core 1400, flows out from the second outlet 1440, and sequentially enters the second connecting pipe 1000 and the second inlet 120. The pre-filtered water and pure water are regulated and controlled by a single reversing valve core 1400, integrating the traditional two-valve-core control switch into a single-valve-core control switch, saving space.

[0058] In some embodiments of the present invention, a side spray assembly 1700 and a faucet housing 1800 are also included. A fixing member is fixedly connected to the faucet housing 1800. A first connecting pipe 900 and a second connecting pipe 1000 are located inside the faucet housing 1800. The integrated valve body 1100 further forms a third valve core cavity 1150, a fourth valve core cavity 1160, a second water outlet 1170, and a third water outlet 1180. The third valve core cavity 1150 is connected to the main water channel 1110 and has a third outlet. One end of the third water outlet 1180 is connected to the third outlet, and the other end is connected to the first water inlet 110 through the first connecting pipe 900. The third valve core cavity 1150 houses a first switch valve core 1181, which controls the flow between the main water passage 1110 and the third outlet water passage 1180. A fourth valve core cavity 1160 is connected to the main water passage 1110 and has a fourth outlet. One end of the second outlet water passage 1170 is connected to the fourth outlet, and the other end is connected to the side spray assembly 1700. A second switch valve core 1161 is installed within the fourth valve core cavity 1160 and controls the flow between the main water passage 1110 and the second outlet water passage 1170. The side spray assembly 1700 has at least one water pattern. The water pattern of the side spray assembly 1700 can be one or more of the following: shower water, waterfall water, pulse water, or granular water. The side spray assembly 1700 has a button for switching water patterns, meeting diverse kitchen usage needs. Hot and cold water / pre-filtered water enters the main water circuit 1110, and supplies water to the side spray assembly 1700 and the aerator through the second water outlet 1170 and the third water outlet 1180 respectively. Opening the first switch valve core 1181 controls the water output from the aerator, and opening the second switch valve core 1161 controls the water output from the side spray assembly 1700. The side spray assembly 1700, the faucet housing 1800, and the integrated valve body 1100 are installed in a main housing 1900. The product has a simple appearance, multiple functions, and strong practicality.
