In practical application, when both the water inlet body 10 and the water outlet body 20 are made of metal materials, the left water inlet portion 11 can be welded with the water outlet body 20 to fixedly connect the water inlet body 10 and the water outlet body 20, and when both the water inlet body 10 and the water outlet body 20 are made of plastic materials, the left water inlet portion 11 is in interference fit with the accommodating cavity 22 to fixedly connect the water inlet body 10 and the water outlet body 20. It should be understood that the manner of securing the inlet body 10 and the outlet body 20 is not limited thereto.
After the connection is completed, as shown in fig. 4-5, the water outlet device is provided with a first water channel 01, at least two second water channels 02 and a gas-water mixing cavity 03. Specifically, the first hole 202 forms a first water channel 01, the second hole 203 forms a second water channel 02, that is, the first water channel 01 and the second water channel 02 are formed on the rectifier 200, the rectifier 200 is installed in the housing 100 and encloses with the housing 100 to form a bowl-shaped cavity, the bowl-shaped cavity forms a gas-water mixing cavity 03, the bowl wall and the bowl bottom are both formed on the water outlet 20, in this embodiment, the arc-shaped cavity wall 212 of the water outlet cavity 21 forms a bowl wall, the cavity bottom of the water outlet cavity 21 forms a bowl bottom, that is, the water outlet 211 is located at the bowl bottom of the bowl-shaped cavity, the end face of the rectifier 200 facing the water outlet 211 forms the end face where the bowl opening of the bowl-shaped cavity is located, and the water outlet ends of the first water channel 01 and the second water channel 02 form the water inlet end of the gas-water mixing cavity 03, that is, the first water channel 01 and the second water channel 02 are communicated with the gas-water mixing cavity 03 at the bowl opening of the gas-water mixing cavity 03.
It is known that, in this embodiment, each second water channel 02 is uniformly distributed around the circumference of the first water channel 01, and the water outlet direction of the second water channel 02 is parallel to the water outlet direction of the first water channel 01, so that the turbulence generated by the mutual interference of the water flows of the first water channel 01 and the second water channel 02 is avoided, the extending direction of the second water channel 02 is parallel to the extending direction of the first water channel 01, and the water passing area of the second water channel 02 is smaller than that of the first water channel 01.
It can be seen that in this embodiment, the inner diameter of the air-water mixing chamber 03 gradually decreases along the water outlet direction, the air-water mixing chamber 03 is connected to the first water channel 01 and the second water channel 02 and is provided with a water outlet 211, the water outlet direction of the first water channel 01 faces the water outlet 211, the water passing area of the port of the first water channel 01 connected to the air-water mixing chamber 03 is smaller than the water passing area of the water outlet 211, and an impact surface 031 for the water flow of the second water channel 02 to impact is provided in the air-water mixing chamber 03 towards the second water channel 02 so that the water flow of the second water channel 02 forms bubble water in the air-water mixing chamber 03. Wherein the bowl wall of the bowl-shaped cavity forms the impact surface 031.
The working principle is as follows:
the water flows into the first water channel 01 and the second water channel 02 after entering the water inlet cavity 112 from the water inlet channel 121, because the water flow area of the water flows in the first water channel 01 and the second water channel 02 is reduced, the water flow is accelerated in the first water channel 01 and the second water channel 02, because the water outlet direction of the first water channel 01 faces the water outlet 211 and the water flow area of the port of the first water channel 01 communicated with the air-water mixing cavity 03 is smaller than the water flow area of the water outlet 211, the water flow of the first water channel 01 can directly flow out of the water outlet 211 without being disturbed, the water flow of the second water channel 02 is impacted on the impact surface 031 of the air-water mixing cavity 03, the water flow of the second water channel 02 is blocked and impacted, namely, the water flow of the second water channel 02 is limited, so that the water flow mainly flows out through the first water channel 01, the water pressure is also concentrated on the water flow of the first water channel 01, the water flow of the first water channel 01 is fast, negative pressure is formed in the air-water mixing cavity 03, a large amount of air is sucked from the water outlet 211, a part of the water flow of the second water channel 02 is broken to form particle water and air to be fully mixed, a part of the water flow is wrapped in the water channel, and the water flow is mixed with the water flow around the water channel 01, and the water flow is formed by the water flow of the water channel 01, and the water flow is mixed with the water channel is high, and the water flow is formed by the water channel and the water channel is high, and the water channel is mixed with the water channel and the water channel is high, and the water is mixed.
It can be seen that, by adopting the technical scheme, because the water pressure is concentrated on the water flow of the first water channel 01, when the water pressure is lower, the flow speed of the water flow of the first water channel 01 is also faster so as to generate a good air suction effect, the arrangement of the impact surface 031 further enables the water flow to be fully mixed with air, so that the air content of the formed bubble water is high, the stabbing-free feeling is softer during use, the stain flushing effect is good, and because the water passing area of the second water channel 02 is smaller than the water passing area of the first water channel 01, the water pressure is further concentrated in the first water channel 01, and the ultra-soft bubble water is more convenient to form under low pressure. In addition, this technical scheme still creatively locates air-water mixing chamber 03 upstream of atmospheric inlet, and air is in air-water mixing chamber 03 against the play water direction, and need not to set up the air inlet channel that is used for feeding air alone, and the structure is ingenious and simpler.
More preferably, because the directions of broken particle water are different, the water flow is more turbulent, the impact surface 031 is positioned on the bowl wall of the bowl-shaped cavity, namely, the impact surface 031 is an arc surface, so that most of water flows back, only a small part of water flows back to form particle water, the water flow in the air-water mixing cavity 03 is prevented from being excessively turbulent, the water flow flowing back can wrap a large amount of air, the air bubble water formed by the air backflow wrapping is higher in air content relative to the air bubble water formed by mixing the particle water and the air, and the cleaning effect is softer.
Correspondingly, the invention also improves the water outlet effect. Referring to fig. 6-8, the number of the second water channels 02 is at least three, the water outlet 211 is polygonal, the number of sides of the polygon is equal to that of the second water channels 02, and the impact positions of the second water channels 02 on the impact surface 031 are respectively in one-to-one correspondence with the sides of the water outlet 211. Thus, when the water flows of the second water channel 02 flow out of the water outlet 211, the water flows of two adjacent second water channels 02 collide and gather at the outer corners of the polygon, and as the water flow speed of the first water channel 01 is high, the water flows of the first water channel 01 flow out of the water outlet 211 and then are absorbed by the water gathered at the outer corners, so that sheet-shaped water is formed, and the flowing water flows are gathered into a bundle after being far away from the water outlet 211, so that a plurality of sheet-shaped water surrounding a middle water column is formed, and the appearance is more attractive. Further, the water outlet 211 is in a regular polygon shape, and the first hole 202 is coaxial with the water outlet 211, that is, the first water channel 01 is coaxial with the water outlet 211, so that the water flowing out of the water outlet 211 forms a water spray which is more symmetrical and more attractive.
More preferably, the impact positions of the second water channels 02 on the impact surface 031 are respectively corresponding to the middle points of the sides of the water outlet 211, so that the flaky water formed by the corresponding corners of the water outlet 211 is more consistent, and the water flowing out of the water outlet 211 is more symmetrical and more attractive. Figures 8-9 illustrate the effect of the regular triangle of the outlet 211.
However, it should be understood that the water outlet 211 may be in other shapes, such as a circle, the number of the second water channels 02 is at least three, each second water channel 02 is uniformly distributed around the circumference of the water outlet 211, referring to fig. 1-5, when the water outlet 211 is circular, the water flow of the second water channel 02 is impacted on the arc-shaped impact surface 031 to form inverted water and wrap the water flow of the middle first water channel 01 to form a large-volume water, the water flow flows out under the strong pressure of the water flow of the first water channel 01 to form large-particle water, the water flow is discharged from the water outlet 211, the water discharge amount of the air-water mixing cavity is reduced at one moment, and when the water flow is discharged again, a space is formed between the water flow and the water flow discharged last, so that an obvious large-particle water effect is formed, and the appearance is good.
The invention also provides an intelligent toilet flushing part, as shown in fig. 10, wherein one water outlet end of the flushing part is provided with the water outlet device in the embodiment. So, the bubble water air content that forms is high, and no stinging is felt more softly when using, washes the spot effect good, and simple structure, low cost, user experience is good.
It should be understood that the water outlet device of the present invention may also be installed at the water outlet end of a shower or a pull-out faucet.
