In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0024] Referring to FIGS. 1-5, an embodiment of the present application proposes a water outlet device, comprising an ultrasonic generator 12 and a cutting device 20, wherein the ultrasonic generator 12 has an oscillation cavity and a liquid inlet and a liquid outlet communicating with the oscillation cavity, the liquid inlet is arranged to communicate with an external water supply device, and the liquid outlet is connected with the cutting device 20. The cutting device 20 includes a cutting shell 21 and a cutting member 22, the cutting shell 21 is provided with a fluid passage communicating with the liquid outlet of the ultrasonic generator 12, and the cutting member 22 is arranged in the fluid passage. The cutting member 22 is arranged to cut the gas in the fluid passage, and the cutting member 22 and the ultrasonic generator 12 are provided with an air inlet a communicating with the fluid passage.

[0025] The fluid medium can flow through the ultrasonic generator 12 and the cutting device 20 respectively, both of which can form bubbles but the reasons for forming bubbles are different, and the particle size range of the generated bubbles is also different. Among them, the ultrasonic generator 12 can generate high-frequency vibration and act on the fluid medium flowing through the ultrasonic generator 12, so that tensile stress occurs inside the fluid medium to form negative pressure, and the decrease in pressure makes the gas originally dissolved in the fluid medium supersaturated, and escapes from the fluid medium to form bubbles. The bubbles formed by the ultrasonic generator 12 are mostly nanobubbles with a particle size of less than 0.1 μm, and the cutting device 20 cuts the gas entering the fluid channel from the gas inlet a to form bubbles. The cutting member is provided at the outlet of the ultrasonic generator, and the particle size of the bubbles formed by the cutting member is larger than that of the bubbles formed by the ultrasonic generator 12. Compared with nanobubbles, it is easier to form obvious turbidity phenomenon, and the user experience is good.

[0026] It should be emphasized that the gas inlet a is provided between the cutting member 22 and the ultrasonic generator 12. There are at least the following four possibilities: in one embodiment, the gas inlet a is provided on the cutting shell 21 and located upstream of the cutting member 22; in another embodiment, the ultrasonic generator 12 and the cutting device 20 are connected by a connecting pipe, and the gas inlet a is provided on the connecting pipe; in another embodiment, the ultrasonic generator 12 and the cutting device 20 are connected by a connecting pipe, and the gas inlet a is provided at the connection between the cutting shell 21 and the connecting pipe, that is, the gas inlet a is the gap between the cutting shell 21 and the connecting pipe; in another embodiment, the ultrasonic generator 12 and the cutting device 20 are connected by a connecting pipe, and the gas inlet a is provided at the connection between the connecting pipe and the ultrasonic generator 12, that is, the gas inlet a is the gap between the ultrasonic generator 12 and the connecting pipe.

[0027] Of course, if the cutting shell 21 is directly connected to the ultrasonic generator 12, the gas inlet a can also be the gap formed at the connection between the cutting shell 21 and the ultrasonic generator 12.

[0028] In one embodiment, the cutting member 22 includes a 400-600 mesh filter screen. At this time, the cutting member 22 forms micro-nanobubbles with a diameter of 0.1-1 μm. Micro-nanobubbles not only easily form obvious turbidity phenomenon, but also open the pore channels, which is conducive to the deep cleaning of pores by the nanobubbles formed by the ultrasonic generator 12 to remove dirt and oil. That is, the ultrasonic generator 12 and the cutting device 20 cooperate to achieve better cleaning effect on the skin.

[0029] In one embodiment, the filter screen included in the cutting member 22 is a 600 mesh filter screen and is provided with a double layer. At this time, the turbidity effect is the most obvious.

[0030] It can be understood that there are various ways for the gas to enter the fluid channel through the gas inlet a. For example, in an embodiment, the gas inlet a is connected with a gas pump, and the gas pump is used to pump the gas into the fluid channel.

[0031] In another embodiment, the cutting shell 21 and / or the connecting pipe comprises a Venturi tube, or the cutting shell 21 and the connecting pipe together form a Venturi tube. According to the Venturi principle, the flow rate of the liquid is inversely proportional to the size of the flow area in the pipeline, and the flow rate can be increased by reducing the flow area. According to Bernoulli's law, the increase in flow rate is accompanied by an increase in fluid pressure, which can form a negative pressure and thus produce an adsorption effect. That is, the Venturi tube itself can suck the gas into the fluid channel without the help of an external gas supply device such as a gas pump. Moreover, the Venturi tube itself has a flow limiting effect, and the Venturi tube is arranged downstream of the ultrasonic generator 12, which can increase the action time of the ultrasonic generator 12, help to form nanobubbles, and thus enhance the cleaning effect.

[0032] Referring to FIGS. 2-4, the ultrasonic generator 12 comprises an ultrasonic driving member and a vibrating shell 121, and an oscillation cavity is arranged in the vibrating shell 121. The ultrasonic driving member is configured to provide vibration power to the vibrating shell 121 under the action of an external voltage. The structure of the ultrasonic driving member and the principle of generating vibration belong to the related art, and will not be described in detail here. Considering that the fluid medium used by the water outlet device is generally tap water, the vibrating shell 121 is made of stainless steel, which has high hardness and strong corrosion resistance.

[0033] In an embodiment, the water inlet level of the vibrating shell 121 is lower than the water outlet level, that is, the height of the liquid inlet is lower than the height of the liquid outlet. Such an arrangement can increase the difficulty of the fluid medium flowing out of the oscillation cavity, increase the action time of the ultrasonic generator 12 on the fluid medium, form more nanobubbles, and achieve better cleaning effect.

[0034] For example, the vibrating shell 121 comprises a main shell 1211 and a liquid outlet 1212. The liquid inlet is arranged at the bottom of the vibrating shell 121, and the liquid outlet 1212 is arranged in an L shape. The first end of the liquid outlet 1212 vertically penetrates the main shell 1211 from the bottom of the main shell 1211 to form a liquid outlet, and the second end is arranged outside the main shell 1211 and connected with the cutting device 20. It can be understood that the first end of the liquid outlet 1212 is the liquid outlet.

[0035] In an embodiment, the diameter of the liquid inlet is greater than the diameter of the liquid outlet, so as to increase the residence time of the fluid medium in the oscillation cavity.

[0036] In an embodiment, the water outlet device comprises a main machine 10, the main machine 10 comprises a shell 11, the ultrasonic generator 12 and a main control PCB 13, the cutting device 20 is arranged outside the shell 11 and connected with the shell 11, the ultrasonic generator 12 and the main control PCB 13 are both built-in in the shell 11, and the main control PCB 13 is electrically connected with the ultrasonic generator 12 to drive the ultrasonic generator 12.

[0037] Referring to FIG. 2 and FIG. 3, in order to reduce the difficulty of connecting the ultrasonic generator 12 with the external water supply device, the main machine 10 further comprises a first connector 14, a first end of the first connector 14 is communicated with the liquid inlet, and a second end of the first connector 14 is arranged to be connected with the external water supply device by penetrating the shell 11 from one side of the shell 11.

[0038] In an embodiment, in order to prevent the fluid medium from flowing back, a check valve is arranged in the first connector 14, which belongs to the related art and will not be described in detail here.

[0039] Similarly, the main machine 10 further comprises a second connector 16, a first end of the second connector 16 is communicated with the liquid outlet of the ultrasonic generator 12, and a second end of the second connector 16 is connected with the cutting device 20 by penetrating the shell 11 from the shell 11.

[0040] In an embodiment, the water outlet device is applied beside a washbasin in a bathroom as a faucet. At this time, the main machine 10 further comprises a faucet pipe 17 outside the shell 11, a first end of the faucet pipe 17 is connected with the shell 11 through the second connector 16 and communicated with the ultrasonic generator 12, and a second end of the faucet pipe 17 is connected with the cutting device 20. Considering the use height suitable for human body, the second connector 16 penetrates the shell 11 from the top of the shell 11 and is connected with the faucet pipe 17, at this time, based on the orientation of the liquid outlet port 1212, the water outlet device further comprises a connecting pipe 15, two ends of the connecting pipe 15 are respectively connected with the first end of the second connector 16 and the second end of the liquid outlet port 1212. Exemplarily, the connecting pipe 15 adopts a flexible pipe, which reduces the assembly difficulty compared with a rigid pipe.

[0041] It can be understood that the faucet pipe 17 and the connecting pipe 15 both belong to connecting pipes.

[0042] In order to flexibly adjust the outlet direction of the cutting device 20, the second connector 16 adopts a rotatable connector, and at the same time, the main machine 10 further comprises a third connector 18, the third connector 18 also adopts a rotatable connector.

[0043] For example, the second joint 16 includes a first adapter, a rotary disc and a base, wherein the rotary disc is embedded on the shell 11, the base and the first adapter are respectively arranged on the upper and lower sides of the rotary disc and communicate with the rotary disc, the first adapter communicates with the connecting pipe 15, the base communicates with the faucet pipe 17, the base is rotationally connected with the rotary disc and the faucet pipe 17, and the rotation axis around which the base rotates relative to the rotary disc is perpendicular to the rotation axis around which the faucet pipe 17 rotates relative to the base; the third joint 18 includes a second adapter, a ball head connecting piece and a third adapter, the two ends of the ball head connecting piece are arranged at an angle and are respectively provided with ball heads, wherein the ball head at one end is connected with the cutting device 20 through the third adapter, and the ball head at the other end is connected with the faucet pipe 17 through the second adapter, and the second adapter is detachably connected to the second end of the faucet pipe 17.

[0044] In other embodiments, the water outlet device can also be installed on the shower head.

[0045] In order to effectively monitor the formation concentration of bubbles in the oscillation cavity, the main machine 10 further includes at least two groups of laser transceivers connected with the main control PCB 13, wherein one group is arranged between the ultrasonic generator 12 and the external water supply device, for example, in the first joint 14, and the other group is arranged between the ultrasonic generator 12 and the cutting device 20, for example, in the connecting pipe 15. The laser transceiver includes a laser generator and a laser receiver arranged opposite to each other.

[0046] The bubbles have a scattering effect on the laser beam emitted by the laser generator, which can cause the laser beam intensity to weaken. Based on this characteristic, the main control PCB 13 can determine the formation concentration of bubbles by comparing the laser beam intensities received by the laser receivers in the two groups of laser transceivers, thereby dynamically controlling the number of bubbles in the fluid medium to reduce the vibration frequency of the ultrasonic generator 12 when the bubble formation concentration is saturated, so as to reduce energy consumption.

[0047] In an embodiment, the main machine 10 further includes a battery for supplying power to the main control PCB 13, and the battery is arranged in the shell 11.
