[0050] The utility model will be described in more detail below with reference to the preferred embodiments and accompanying drawings.
[0051] The embodiment provides an air bubble water device, and the specific structure is as shown in Figure 1 、 Figure 2 and Figure 3 , the air bubble water device comprises a flow limiter 1 and a jet flow device 2 coaxially arranged with the flow limiter 1, the first end diameter of the jet flow device 2 is less than the second end diameter of the jet flow device 2, and the air bubble water device further comprises:
[0052] A gas mixing cavity 3 is sleeved on the outer peripheral side of the jet flow device 2 and is coaxially arranged with the jet flow device 2, the gas mixing cavity 3 is communicated with the outlet of the air bubble water device, the gas mixing cavity 3 is communicated with the jet flow device 2 through a first communication hole 21, a plurality of first communication holes 21 are arranged at intervals around the axis direction of the jet flow device 2, and the diameter of the first communication hole 21 is less than the first end diameter of the jet flow device 2.
[0053] Specifically, the flow limiter 1 and the jet flow device 2 are both structures for making air bubble water in the prior art, wherein the flow limiter 1 is communicated with the inlet of the air bubble water device, the connection part of the flow limiter 1 and the jet flow device 2 is used for attracting air, so that the air enters the jet flow device 2 and mixes with the water entering the jet flow device 2 to form air bubble water. The gas mixing cavity 3 is formed on the outer peripheral side of the jet flow device 2 and is coaxially arranged with the jet flow device 2, and from the appearance, the gas mixing cavity 3 is sleeved on the jet flow device 2, compared with the mode that the gas mixing cavity 3 and the jet flow device 2 are sequentially connected, the mode that the gas mixing cavity 3 is filled on the outer peripheral side of the jet flow device 2 makes the gas mixing cavity 3 occupy less space, and the air bubble water device can be arranged in a smaller space, and the space utilization is improved.
[0054] The first end of the jet 2 is in communication with the flow restrictor 1, and the second end of the jet 2 is arranged close to the outlet of the bubble water device. A baffle is arranged in the jet 2, the baffle is arranged corresponding to the first end of the jet 2 and is used to block the bubble water. The jet 2 is in communication with the mixing cavity 3 through a first communication hole 21, the first communication hole 21 is arranged on the jet 2 and close to the second end of the jet 2. A plurality of first communication holes 21 are arranged around the axial direction of the jet 2, the plurality of first communication holes 21 are annularly arranged on the outer surface of the jet 2 and penetrate the jet 2. The diameter of the first communication hole 21 is smaller than the diameter of the first end of the jet 2. By arranging the diameter of the first communication hole 21 to be smaller than the end of the minimum diameter of the jet 2, the air mixed with the water in the jet 2 is slowed down when flowing from the first communication hole 21 to the mixing cavity 3 after being blocked by the baffle. The slowed down bubble water can fully contact and mix with air in the mixing cavity 3 to form more dense bubble water, that is, the bubble effect of the bubble water is more significant. For example, the bubble water formed appears white in appearance.
[0055] The first communication hole 21 can be a circular hole or other shaped hole, for example, a rectangular hole, which is a prior art and will not be described in detail here.
[0056] Further, in the embodiment, the plurality of first communication holes 21 are arranged along the length direction of the jet 2 and form a plurality of rows of first communication holes 21, and the included angle between the two adjacent rows of first communication holes 21 is 10°-20°.
[0057] Specifically, a plurality of first communication holes 21 are arranged around the axial direction of the jet 2, and the number of first communication holes 21 is increased and arranged regularly to improve the speed reduction effect of the bubble water and ensure sufficient flow of the bubble water. The plurality of first communication holes 21 are located on the same straight line along the length direction of the jet 2, thereby forming a row of first communication holes 21. Similarly, the remaining first communication holes 21 are also located on the same straight line along the length direction of the jet 2, and the difference is that the first communication holes 21 are arranged at intervals around the axial direction of the jet 2 from the previous row of first communication holes 21, and the interval between the two adjacent rows of first communication holes 21 is an included angle of 10°-20°. By arranging the interval to be 10°-20°, it is avoided that the number of first communication holes 21 is too small when the interval is too large, so that the speed of the bubble water flowing out of the first communication hole 21 is too fast, and it is also avoided that the hole diameter of the first communication hole 21 is too large, which will interfere with the adjacent row of first communication holes 21.
[0058] In the embodiment, a second communication hole 22 is arranged between the outlet of the bubble water device and the mixing cavity 3, and a plurality of second communication holes 22 are arranged at intervals around the axial direction of the jet 2.

[0059] Specifically, the mixing cavity 3 is communicated with the outlet of the bubble water outlet device through the second communication hole 22, which is arranged close to the second end of the fluidic device 2 and is located behind the first communication hole 21 along the direction of the bubble water flow. The principle is that the water flows into the flow restrictor 1, the fluidic device 2, the first communication hole 21, the mixing cavity 3 and the second communication hole 22 in turn through the inlet of the bubble water outlet device, and finally flows out through the outlet of the bubble water outlet device. The diameter of the second communication hole 22 is also smaller than the diameter of the first end of the fluidic device 2, so that the bubble water is decelerated again through the second communication hole 22 with a smaller diameter. It can be understood that the first deceleration is the deceleration when the bubble water flows into the mixing cavity 3 through the first communication hole 21. On the basis of the cooperation between the first communication hole 21 and the second communication hole 22, the bubble water mixing effect is further improved compared with the case where only the first communication hole 21 is arranged.
[0060] In the embodiment, a plurality of second communication holes 22 are arranged along the length direction of the fluidic device 2 and form a plurality of rows of second communication holes 22, and the included angle between the two adjacent rows of second communication holes 22 is 10°-20°.
[0061] Specifically, a plurality of second communication holes 22 are arranged around the axial direction of the fluidic device 2, and the number of second communication holes 22 is increased and arranged regularly to improve the deceleration effect of the bubble water and ensure the sufficient flow of the bubble water. A plurality of second communication holes 22 are located on the same straight line along the length direction of the fluidic device 2, thereby forming a row of second communication holes 22. Similarly, the remaining second communication holes 22 are also located on the same straight line along the length direction of the fluidic device 2, and the difference is that the second communication holes 22 are arranged at intervals around the axial direction of the fluidic device 2, and the interval between the two adjacent rows of second communication holes 22 is an included angle of 10°-20°. By setting the interval to 10°-20°, the speed of the bubble water flowing out of the second communication hole 22 is prevented from being too fast due to too few second communication holes 22, and the case that the hole diameter of the second communication hole 22 is too large to interfere with the adjacent row of second communication holes 22 is prevented.
[0062] In the embodiment, the number of first communication holes 21 in each row is 6, and the number of second communication holes 22 in each row is 5. Of course, in other embodiments, the number of first communication holes 21 in each row and the number of second communication holes 22 in each row can also be other numbers. The purpose is to ensure the flow of the bubble water on the basis of the deceleration and mixing of the bubble water, and to prevent the flow from being too small to affect the actual use experience of the user.
