When the three nets 20 are under water pressure due to water flow, the three nets 20 will be spaced from sparse to dense according to the water pressure from small to large, and the spacing of the plural nets 20 will correspond to each other. Rice bubbles. The three nets 20 described in this embodiment, although the number of the nets 20 is three in this embodiment, this is only an implementation aspect, and this creation is not limited to this number.

The body 10 of this embodiment includes a water inlet 16 and a water outlet 17. The water inlet 11 is at one end of the water inlet 16, and the flow channel 13 is inside the water inlet 16; and the water outlet 12 is At one end of the water outlet 17 and the chamber 15 is inside the outlet 17, the water inlet 16 and the outlet 17 are connected to communicate the small diameter section 132 and the chamber 15. In different implementations, the main body 10 can also be an integral form, that is, the water inlet portion 16 and the water outlet portion 17 are integrally formed.

In this embodiment, the water inlet 16 has a first joint 161 at the other end different from the water inlet 11, and the first joint 161 is a male screw in this embodiment; the water outlet 17 is different from the water outlet 11 The other end of the end 12 has a second joint 171. The second joint 171 is a female thread in this embodiment. The water inlet 16 and the water outlet 17 are the same as the first joint 161 and the second joint 171. Threaded and connected. The air passage 14 of this embodiment is a through hole that radially penetrates the water inlet 16 to connect the small diameter section 132 and the outside, and the air passage 14 can also communicate with the small diameter section 132 and the outside in different implementations, such as thin Sew. In this embodiment, the water inlet 16 has a locking portion 162 at the water inlet 11, so that the locking portion 162 can be connected to the water supply faucet 200, or can be connected to the shower head, or can be connected to similar pipes for water outlet.

The main body 10 of this embodiment is provided with a rod 18 which extends axially in the chamber 15. Each net body 20 has a perforation 21 respectively, and each net body 20 passes through the rod 18 through the perforation 21 and is parallel to each other. The three compression springs 30 are sleeved on the rod 18, and the plurality of net bodies 20 are respectively supported by the plurality of compression springs 30 and are normally away from each other. In this embodiment, the compression spring 30 is taken as the implementation of the elastic member, but it is not limited to this.

In actual use, the microbubble generating device 100 is locked to the faucet 200 by the locking portion 162 of the water inlet 16, and when the faucet 200 is turned on, water flows from the water inlet 11 through the flow channel 13 and passes through the chamber 15. It flows out from the water outlet 12. When the water flows through the flow channel 13, it first flows through the large diameter section 131 and then flows through the small diameter section 132. At this time, according to Berlier's law, the water flow in the small diameter section 132 is formed due to the faster flow rate and the lower pressure, which is relatively external Under negative pressure, air will be continuously drawn into the small diameter section 132 from the air passage 14, and thus bubbles will be formed along with the water flow and flow to the chamber 15. When the water pressure of the water flow is large enough (for example, the water pressure is 1.5kg/cm ² ), the net body 20 is compressed by the water pressure to compress the compression spring 30, and the three net bodies 20 become denser (as shown in the figure) 5), due to the large resistance to the water flow through the three nets 20, the water flowing through the three denser nets 20 will generate a large number of nano bubbles; if the water pressure of the water becomes smaller (such as water The pressure is 1kg/cm ² ). At this time, the net body 20 will still be compressed by the water pressure to compress the compression spring 30, but the three net bodies 20 are relatively sparse (as shown in Figure 6), but the water flows through the three The resistance of the net body 20 is reduced, but the water flowing through the three net bodies 20 can still generate a sufficient amount of nano bubbles.

In this way, because the plurality of nets 20 can vary from small to large according to the water pressure, the distance between the nets 20 can be from sparse to dense, and the plurality of nets 20 can generate nano bubbles of corresponding sizes when the water pressure In the larger case, the net bodies 20 are compressed and the distance between each other is relatively close. After the water flows through the plural net bodies 20 in sequence, the amount of nano bubbles that can be generated is large; even in the case of lower water pressure, the plural Although the net body 20 changes from dense to sparse, the water flow through the plural net bodies can still generate a sufficient amount of nanobubbles. Therefore, no matter the water pressure, there are enough nanobubbles in the effluent, which is compared with conventional microbubbles. As far as the generating device is concerned, it can provide a better cleaning effect.

The above-mentioned embodiments are only used to illustrate the present invention, and are not used to limit the scope of the present invention. All modifications or changes made without violating the spirit of the present invention belong to the scope of the present invention.
