[0023] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the accompanying drawings.

It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0027] Refer to Figures 1 - 5As shown in the figure, in an embodiment of the present utility model, a water outlet device is proposed, which includes an ultrasonic generator 12 and a cutting device 20. The ultrasonic generator 12 has an oscillation cavity, as well as a liquid inlet and a liquid outlet communicating with the oscillation cavity. The liquid inlet is used to communicate with an external water supply device, and the liquid outlet is connected to the cutting device 20. The cutting device 20 includes a cutting housing 21 and a cutting member 22. A fluid channel communicating with the liquid outlet is penetrated through the cutting housing 21. The cutting member 22 is arranged in the fluid channel and is used to cut the gas in the fluid channel. An air inlet a communicating with the fluid channel is arranged between the cutting member 22 and the ultrasonic generator 12.

[0028] In the above water outlet device, the fluid medium can flow through the ultrasonic generator 12 and the cutting device 20 respectively. Both can form bubbles, but the reasons for forming bubbles are different, and the ranges of the bubble diameters generated are also different. Among them, the ultrasonic generator 12 can generate high-frequency vibrations and act on the fluid medium flowing through the ultrasonic generator 12, causing tensile stress to appear inside the fluid medium to form negative pressure. The reduction of pressure makes the gas originally dissolved in the fluid medium supersaturated and escape from the fluid medium to form bubbles. The bubbles formed by the ultrasonic generator 12 are mostly nano-bubbles with a diameter less than 0.1 μm, while the cutting device 20 cuts the gas entering the fluid channel from the air inlet a to form bubbles. The diameter of the formed bubbles is larger than that of the bubbles formed by the ultrasonic generator 12, and it is easier to form an obvious turbidity phenomenon compared with nano-bubbles, providing a good user experience.

[0029] It should be emphasized that there are at least the following three possibilities for the air inlet a to be arranged between the cutting member 22 and the ultrasonic generator 12: In one embodiment, the air inlet a is arranged on the cutting housing 21 and 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 air inlet a is arranged on the connecting pipe; in still another embodiment, the ultrasonic generator 12 and the cutting device 20 are connected by a connecting pipe, and the air inlet a is arranged at the connection of the cutting housing 21 and the connecting pipeline, that is, the air inlet a is the gap between the cutting housing 21 and the connecting pipeline; in yet another embodiment, the ultrasonic generator 12 and the cutting device 20 are connected by a connecting pipe, and the air inlet a is arranged at the connection of the connecting pipe and the ultrasonic generator 12, that is, the air inlet a is the gap between the ultrasonic generator 12 and the connecting pipeline.

[0030] Of course, if the cutting housing 21 is directly connected to the ultrasonic generator 12, the air inlet a can also be the gap formed at the connection of the cutting housing 21 and the ultrasonic generator 12.

[0031] In one embodiment, the cutting member 22 includes a filter screen with a mesh size of 400 - 600 meshes. At this time, most of the bubbles formed by the cutting member 22 are micro-nano bubbles with diameters between 0.1 μm and 1 μm. Micro-nano bubbles are not only prone to form an obvious turbidity phenomenon, but also can open the pore channels, which is beneficial to cooperate with the nano bubbles formed by the ultrasonic generator 12 to penetrate deep into the pores to remove dirt and oil. That is to say, the ultrasonic generator 12 and the cutting device 20 cooperate to achieve a better cleaning effect on the skin.

[0032] In one embodiment, the filter screen included in the cutting member 22 is a 600-mesh filter screen and is provided with two layers. At this time, the turbidity effect is the most obvious.

[0033] It can be understood that there are various ways for the gas to enter the fluid channel through the air inlet a. For example, in one embodiment, the air inlet a is connected to an air pump, and the air pump pumps gas into the fluid channel.

[0034] In another embodiment, the cutting housing 21 and / or the connecting pipeline includes a Venturi tube, or the cutting housing 21 and the connecting pipeline together form a Venturi tube. According to the Venturi principle, in a pipeline, the flow rate of a liquid is inversely proportional to the size of the flow-through area. By reducing the flow-through area, the liquid flow rate can be increased; and according to Bernoulli's law, the increase in flow rate is accompanied by an increase in fluid pressure, which can form a negative pressure, thereby generating an adsorption effect. That is, the Venturi tube itself can suck gas into the fluid channel without the need to rely on an external gas supply device such as an air pump to provide gas. Moreover, the Venturi tube itself has a flow-limiting effect. The Venturi tube is arranged downstream of the ultrasonic generator 12, which can increase the action time of the ultrasonic generator 12, contribute to the formation of nano bubbles, and further enhance the cleaning effect.

[0035] Reference Figures 2 - 4 As shown, the ultrasonic generator 12 includes an ultrasonic driving member and a vibrating housing 121. The oscillation cavity is arranged inside the vibrating housing 121. The ultrasonic driving member is configured to provide vibration power to the vibrating housing 121 under the action of an external voltage. The structure of the ultrasonic driving member and the principle of generating vibration belong to the prior art and will not be described in detail here. Considering that the fluid medium used in the water outlet device is generally tap water, the vibrating housing 121 is made of stainless steel, which has high hardness and strong corrosion resistance.

[0036] In one embodiment, the water inlet level of the vibrating housing 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 a setting 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, and more nano bubbles can be formed, resulting in a better cleaning effect.

[0037] Specifically, the vibration housing 121 includes a main housing 1211 and a liquid outlet port 1212. The liquid inlet is opened at the bottom of the vibration housing 121, and the liquid outlet port 1212 is arranged in an L shape. Its first end vertically penetrates into the main housing 1211 from the bottom of the main housing 1211 to form a liquid outlet, and the second end is located outside the main housing 1211 for connecting to the cutting device 20. It can be understood that the port of the first end of the liquid outlet port 1212 is the liquid outlet.

[0038] In one embodiment, the caliber of the liquid inlet is larger than that of the liquid outlet to further increase the residence time of the fluid medium in the oscillation cavity.

[0039] In one embodiment, the water outlet device includes a main unit 10. The main unit 10 includes a housing 11, the above-mentioned ultrasonic generator 12, and a main control PCB board 13. The cutting device 20 is arranged outside the housing 11 and connected to the housing 11. The ultrasonic generator 12 and the main control PCB board 13 are both built inside the housing 11, and the main control PCB board 13 is electrically connected to the ultrasonic generator 12 to drive the ultrasonic generator 12.

[0040] Reference Figure 2 and Figure 3 As shown in the figure, in order to reduce the difficulty of connecting the ultrasonic generator 12 to an external water supply device, the main unit 10 further includes a first connector 14. The first end of the first connector 14 is communicated with the liquid inlet, and the second end of the first connector 14 penetrates out of the housing 11 from one side of the housing 11 for connecting to an external water supply device.

[0041] In one embodiment, in order to prevent the reverse flow of the fluid medium, a check valve is arranged inside the first connector 14. The check valve belongs to the prior art and will not be described in detail here.

[0042] Similarly, the main unit 10 further includes a second connector 16. The first end of the second connector 16 is communicated with the liquid outlet of the ultrasonic generator 12, and the second end of the second connector 16 penetrates out of the housing 11 and is connected to the cutting device 20.

[0043] In one embodiment, the water outlet device is used as a faucet beside the washbasin in the bathroom. At this time, the main unit 10 further includes a faucet pipe 17 located outside the housing 11. The first end of the faucet pipe 17 is connected to the housing 11 through the second connector 16 and is simultaneously communicated with the ultrasonic generator 12, and the second end of the faucet pipe 17 is connected to the cutting device 20. Considering the use height of the human body, the second connector 16 penetrates out of the housing 11 from the top of the housing 11 and is connected to the faucet pipe 17. At this time, based on the orientation of the liquid outlet port 1212, the water outlet device further includes a connecting pipe 15. The two ends of the connecting pipe 15 are respectively connected to the first end of the second connector 16 and the second end of the liquid outlet port 1212. More specifically, the connecting pipe 15 is made of a flexible pipe, which reduces the assembly difficulty compared with a rigid pipe.

[0044] It can be understood that both the faucet pipe 17 and the connecting pipe 15 belong to the connecting pipelines.

[0045] In order to flexibly adjust the outlet direction of the cutting device 20, the second joint 16 adopts a rotatable joint. At the same time, the main body 10 further includes a third joint 18, and the third joint 18 also adopts a rotatable joint.

[0046] Specifically, the second joint 16 includes a first adapter, a turntable and a base. The turntable is embedded in the housing 11. The base and the first adapter are respectively arranged on the upper and lower sides of the turntable and communicated with the turntable. The first adapter is communicated with the connecting pipe 15, and the base is communicated with the faucet pipe 17. The base is rotatably connected to the turntable and the faucet pipe 17, and the rotation axis around which the base rotates relative to the turntable 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 joint and a third adapter. The two ends of the ball joint are arranged at an included angle and both ends are provided with ball heads. One of the ball heads is connected to the cutting device 20 through the third adapter, and the other ball head is connected to the cutting device 20 through the second adapter. The second adapter is detachably connected to the second end of the faucet pipe 17.

[0047] In other embodiments, the water outlet device can also be installed on the shower head.

[0048] In order to effectively monitor the formation concentration of bubbles in the oscillation cavity, the main body 10 further includes at least two groups of laser transceivers connected to the main control PCB board 13. One group is arranged between the ultrasonic generator 12 and the external water supply device, for example, arranged in the first joint 14, and the other group is arranged between the ultrasonic generator 12 and the cutting device 20, for example, arranged in the connecting pipe 15. The laser transceiver includes a laser generator and a laser receiver arranged opposite to each other.

[0049] Bubbles have a scattering effect on the laser beam emitted by the laser generator, which can cause the intensity of the laser beam to weaken. Based on this characteristic, the main control PCB board 13 can judge the formation concentration of bubbles by comparing the intensities of the laser beams received by the laser receivers in the two groups of laser transceivers, so as to dynamically control the number of bubbles in the fluid medium. When the formation concentration of bubbles is saturated, the vibration frequency of the ultrasonic generator 12 is reduced to reduce energy consumption.

[0050] In one embodiment, the main body 10 further includes a battery for supplying power to the main control PCB board 13, and the battery is placed in the housing 11.

[0051] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
