In order to allow air outside the water outlet device to enter the water outlet device, an air input channel is usually reserved in the water outlet device, for example, patent documents such as CN211636050U, CN203389782U, CN114991264a and CN217352737U all disclose a scheme that the air input channel is arranged in a gap between two overflow panels and introduces air from the outside atmosphere at a part matching position or a part opening position of the water outlet device, in the schemes, the water hole aperture of a first water passing panel positioned at the upstream is smaller to generate high-speed jet to produce negative pressure so as to attract the outside air into the gap between the two water passing panels, the water hole aperture of a second water passing panel positioned at the downstream is larger to be used for introducing bubble water mixed by the high-speed jet and the air into a cavity at the downstream, and the bubble water flow can be discharged to the outside through a discharge port arranged at the bottom of the cavity after being rectified in the cavity.
In order to ensure the smoothness of water flow, the discharge flow of the discharge port is usually far greater than the water flow of the first water passing panel, but the water outlet structure limits the spray forming effect of the discharged water flow and influences the water outlet pressure, so that the spray forming effect is poor when the water is required to be formed under higher pressure.

The casing 3 overcoat is equipped with sleeve 6, and the air vent 61 with breathing in clearance 5 intercommunication has been seted up to sleeve 6's circumference lateral wall, and sleeve 6's circumference lateral wall outward has seted up the logical groove 62 with air vent 61 intercommunication, and the setting of logical groove 62 is used for when sleeve 6 imbeds in the shell 7, can form the air inlet channel with the outside space intercommunication all the time between the inner wall of shell 7 to ensure to breathe in smoothly. In addition, be provided with the mounting groove 63 that extends the setting along the axial of this sleeve 6 in the end of intaking of sleeve 6, the circumference outer wall of first water passing member 1 and second water passing member 2 all is provided with reference column 8, and reference column 8 and the reference column 8 of first water passing member 1 of second water passing member 2 imbeds in proper order in mounting groove 63 to fix a position.
It can be understood that by defining the positional relationship between the first water passing hole 11 and the second water passing hole 21, and defining the outlet area of the first water passing hole 11, the outlet area of the second water passing hole 21, and the outlet area of the water discharging hole 41, the utility model ensures that the negative pressure generated at the outlet of the first water passing hole 11 by the water passing through the first water passing hole 11 can suck the air in the external space into the air suction gap 5, the air immediately enters the second water passing hole 21 along with the water passing through the second water passing hole 21 and then fully mixes with the water passing through the limited space of the second water passing hole 21 and then enters the cavity defined by the casing 3, and the sum of the projection areas of the outlets of the second water passing hole 21 is less than 2.1 times of the sum of the projection areas of the outlets of the water discharging holes 41, so that the water can be gathered in the casing 3 and generate a certain pressure, the inside of the water discharging device can be kept at the pressure capable of improving the water discharging flow rate of the rectifying piece 4, the water feeding flow rate of the water discharging device is smaller than the water discharging flow rate, and the high-pressure air water can be ensured to be molded, thereby improving the water flower molding effect.
Furthermore, the purpose of defining the projection area of the outlet of each first water passing hole 11 to be located in the projection area of the inlet of the second water passing hole 21 is to ensure that the water flowing through the first water passing hole 11 can all enter the second water passing hole 21 with the air sucked by the negative pressure, if the water cannot all enter, there will necessarily be a part of the water flowing into the air suction gap 5, which will cause on the one hand the air to enter the air suction gap 5 to be blocked and reduce the air suction amount, and on the other hand if the overflow is more or the overflow water flow rate is higher, water will leak outwards along the air suction path.
In some embodiments, the sleeve 6 in the above-described solution is not necessary, and the first water passing member 1, the second water passing member 2 and the housing 3, which are constructed like those shown in fig. 1 to 4, can be directly fitted into the casing 7 even if the sleeve 6 is not provided. Since the housing 7 can be designed to have different shapes, the housing 7 is not necessarily provided together with other parts in actual production, and the sleeve 6 is provided for the main purpose of enabling the sleeve 6 to combine the other parts into an integral part in advance, so that the integral part can be conveniently assembled with different housings 7 after turnover, and the sleeve is a preferable scheme.
In some embodiments, to ensure smoothness of the water outlet, the outlet of each first water hole 11 corresponds to the inlet of one second water hole 21, and this solution is equivalent to providing each water flow discharged from the first water hole 11 with an independent water-air mixing cavity, so as to achieve the best water-air mixing effect; or the outlets of at least two first water passing holes 11 correspond to the inlets of the same second water passing hole 21, so that the size of the inlets of the second water passing holes 21 can be designed to be larger, and a plurality of water flows discharged from the first water passing holes 11 can more accurately enter the second water passing holes 21, thereby avoiding water leakage.
In some embodiments, a boss 12 is provided between the first water passing member 1 and the second water passing member 2 to maintain the suction gap 5. The boss 12 may be disposed on the first water passing member 1 or the second water passing member 2, so as to maintain the air suction gap 5 between the first water passing member 1 and the second water passing member 2, ensure that the air suction gap 5 is always present, and further ensure the formation of bubble water. In the optimal scheme, the boss 12 is arranged between two adjacent first water passing holes 11 or between two adjacent second water passing holes 21 so as to avoid the disappearance of the air suction gap 5 caused by the compression deformation of the first water passing piece 1.
In some embodiments, the sum of the projected areas of the outlets of all the second water passing holes 21 is less than 1.9 times the sum of the projected areas of the outlets of the water discharging holes 41, and the sum of the projected areas of the outlets of all the second water passing holes 21 is greater than 0.6 times the sum of the projected areas of the outlets of the water discharging holes 41, in which the water pressure can be made in a preferable range. Further, the sum of the projected areas of the outlets of all the second water passing holes 21 is equal to 0.8 to 1.3 times the sum of the projected areas of the outlets of the water discharging holes 41, which is the optimum numerical range. In practical design, the above multiple design is set to 0.63, 0.7, 0.85, 0.9, 1, 1.05, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6 or 1.7 times, when the above multiple is higher than 1.9 times, the water pressure is too high, which may cause water flow to overflow reversely from the second water passing hole 21 and the air suction gap 5, resulting in overall water leakage of the product; however, the lower limit of 0.6 times is a lower limit of the molding of various water spray with requirements on water pressure, and the problem of insufficient water discharge pressure may occur when the lower limit is lower than the lower limit, at this time, the water spray formed by high pressure is not molded, the water spray shape is sparse, and the water discharge effect is poor.
In some embodiments, the fairing 4 is integrally formed with the housing 3 or the fairing 4 is rotatably coupled to the housing 3.
In some embodiments, the second water passing member 2 is integrally formed with the housing 3.
In some embodiments, all the first water passing holes 11 and all the second water passing holes 21 are uniformly distributed around the axis of the water outlet device.
In some embodiments, the cross-section of the inlet of the first water passing hole 11 and/or the cross-section of the outlet of the first water passing hole 11 is circular or square. When the cross section of the outlet of the first water passing hole 11 is square, the contact area between the outlet of the first water passing hole 11 and the air suction gap 5 can be enlarged, so that the gas content in water flow is improved, and when the cross section of the outlet of the first water passing hole 11 is round, the air suction amount of water outlet can be more uniform.
In some embodiments, the cross-section of the inlet of the second water passing hole 21 and/or the cross-section of the outlet of the second water passing hole 21 is circular, regular polygon, fan, bar, or ring. When the cross-section of the inlet and outlet of the second water passing hole 21 is the same as the cross-section of the outlet of the first water passing hole 11, it is possible to ensure that the water flow from the first water passing hole 11 attracts the air toward it and then completely enters the second water passing hole 21 to be mixed with the air, and therefore, it is preferable that the cross-section of the outlet of the first water passing hole 11, the inlet and outlet of the second water passing hole 21 are the same. When a plurality of first water passing holes 11 are arranged towards the same second water passing hole 21, the cross section of the inlet of the second water passing hole 21 can be arranged in a fan shape, a bar shape or a ring shape in a matched manner according to the arrangement mode of the first water passing holes 11.
