The invention provides a micro-nano bubble water generating device which can be switched between using micro-nano bubble water and not using micro-nano bubble water, and a user can select to use the micro-nano bubble water or not using the micro-nano bubble water according to the requirement.
When the user chooses to use micro-nano bubble water, control valve 31 closes, and is preferred air inlet 12 department is equipped with the air booster pump, and control air booster pump opens, and gaseous enters into cavity 5 through air inlet 12 in, and when water inlet 11 entered into cavity 5 through water inlet 11, strikes rotary cut structure 2, drives rotary cut structure 2 and rotates, and rotary cut structure 2 rotates and drives fully mixing between gaseous and the liquid, and the micro-nano bubble water of production discharges from delivery port 13 through second apopore 42.
When the user chooses not to use the micro-nano bubble water, namely the user wants to use common water for bathing, the control valve 31 is controlled to be opened and the air booster pump is controlled to be closed. When the air enters the cavity 5 through the air inlet 12 and the water inlet 11 enters the cavity 5 through the water inlet 11, most of the water flows out from the water outlet 13 through the water diversion pipe 3 and the first water outlet 13, and part of the water flows out from the water outlet 13 through the cavity 5 and the second water outlet 42.
The rotary cutting structure 2 comprises a helical blade assembly 21, and the rotary cutting structure 2 has elasticity. When water flows into the cavity 5 from the water inlet 11, a tangential speed is given to the rotary cutting structure 2, and the rotary cutting structure 2 generates vibration under the impact of water due to the elasticity of the rotary cutting structure 2, wherein the vibration comprises the rotation and the up-and-down movement of the rotary cutting structure 2, so that gas and liquid can be sufficiently mixed.
In this embodiment, the water inlet 11 is disposed at the top of the chamber 5, and the water outlet 13 is disposed at the bottom of the chamber 5. The air inlet 12 is arranged on the side wall of the cavity 5 and is close to one end of the water inlet 11.
The helical blade assembly 21 comprises a plurality of helical blades, wherein the helical blades comprise a first helical blade 211 and a second helical blade 212, the first helical blade 211 and the second helical blade 212 are arranged at one end close to the water inlet 11, and the gas inlet 12 is arranged between the first helical blade 211 and the second helical blade 212, so that gas and liquid are fully mixed after gas is introduced. It is avoided that the gas inlet 12 is arranged between the spiral vane assembly 21 and the water inlet 11 such that gas enters the chamber 5 from the gas inlet 12 and then enters the water inlet 11. And the gas inlet 12 is far away from the first water outlet 41 and the second water outlet 42, so that the stroke path of the gas inlet 12 after entering the cavity 5 is prolonged, and sufficient mixing time is ensured before the gas and the liquid flow out from the first water outlet 41 and the second water outlet 42.
A gap exists between the helical blade assembly 21 and the inner wall of the cavity 5, and the gap between the helical blade assembly 21 and the inner wall of the cavity 5 is 0.5-2cm. The gap between the spiral blade assembly 21 and the inner wall of the cavity 5 is reasonably set, so that the situation that the water and the gas are not fully mixed and flow out from the second water outlet 42 due to the fact that the gap between the spiral blade assembly 21 and the inner wall of the cavity 5 is too large is avoided; also avoid screw blade subassembly 21 with clearance undersize between the 5 inner walls of cavity causes screw blade constantly to assault 5 inner walls of cavity when vibrations under the water impact, causes too big noise, or to cavity 5 inner wall wearing and tearing, leads to life to shorten.
The peripheral edge of the baffle 4 is connected with the inner wall of the cavity, and no gap exists between the peripheral edge of the baffle 4 and the inner wall of the cavity. An outlet cavity 6 is formed between the baffle 4 and the water outlet 13. Micro-nano bubble water generated after the gas and the liquid are mixed enters the water outlet cavity 6 through the second water outlet 13 and then flows out through the water outlet 13.
The second apopore 42 sets up around first apopore 41, the second apopore 42 is in interval circumference sets up on baffle 4, just the aperture of second apopore 42 is less than the aperture of first apopore 41. The aperture of the second water outlet 42 is relatively small, so that micro-nano bubble water generated after gas and liquid are mixed is prevented from being discharged from the second water outlet 42 too fast. The first water outlet hole 41 is relatively large, so that when a user does not use micro-nano bubble water and uses ordinary water for bathing, a water outlet effect is guaranteed, and the problem of slow water outlet is avoided.
The distance between the spiral vane members 21 is gradually decreased from top to bottom. The mixing effect between the gas and the liquid is ensured.
The water inlet end of the water diversion pipe 3 is arranged right below the water inlet 11, and the water outlet 13 is arranged right below the water outlet end of the water diversion pipe 3. Preferably, the diameter of the water diversion pipe 3 is larger than or equal to the diameter of the water inlet 11. When a user selects not to use micro-nano bubble water, water flow can directly enter the water distribution pipe 3 after entering the cavity 5 from the water inlet 11, flows out to the water outlet containing cavity 6 through the first water outlet 13 and is discharged from the water outlet 13, and the water body is ensured to flow out quickly.
A water inlet gap is formed between the water inlet end of the distributive pipe 3 and the water inlet 11, and the water inlet gap between the water inlet end of the distributive pipe 3 and the water inlet 11 is 1-5cm. The reasonable clearance of intaking that sets up avoids the clearance of intaking too big, leads to when the user chooses not to use micro-nano bubble water, and the water can not flow out fast through distributive pipe 3, avoids the clearance undersize of intaking, leads to when the user chooses to use micro-nano bubble water function, and the water enters into the poor problem of the impact effect of cavity 5 interior pair rotary-cut blade.
The control valve 31 includes a water valve and a transmission bearing.
The water valve is electrically connected with the air booster pump, and the water valve is electrically connected with the air booster pump. The electrical connection comprises a wired connection and a wireless connection.

In step S103, the current water pressure P1 changes according to the water flow rate, that is, the current water pressure P1 increases as the water flow rate increases.
In step S104, the predetermined differential pressure Δ P0 is 0.03-0.1MPa.
The invention provides a control method of a micro-nano bubble water generating device, which controls a gas injection pressure difference delta P to be larger than a preset pressure difference delta P0, ensures a gas inlet effect and avoids the problem that gas is difficult to enter the micro-nano bubble water generating device due to overlarge water pressure caused by overlarge water flow.

if yes, go to step S101; if not, the process returns to step S13.
And if the user does not use the micro-nano bubble water for bathing, heating the water according to the preset temperature and then discharging the water. The function of entering the bubble water can be switched at any time in the bathing process of bathing without using the micro-nano bubble water by a user, so that the bathing effect is ensured, and the requirements of the user are met better.
In step S103, the method of acquiring the gas injection pressure difference Δ P between the current water pressure P1 and the current intake pressure P2 is:
Δ P = P2-P1, where Δ P is the gas injection pressure difference, P1 is the current water pressure, and P2 is the current forward air pressure. In the use process, it needs to be guaranteed that when the advancing air pressure P2 is larger than the current water pressure P1, the air can enter the micro-nano bubble water generating device.
Step S104, the step of controlling the gas injection pressure difference delta P to be larger than the preset pressure difference delta P0 specifically comprises the following steps:
