Referring to fig. 1 to 5, the micro-nano bubble liquid generating device 100 of the present invention includes a housing 2 and a micro-nano bubbler 1. The housing portion 2 includes a liquid inlet 21, a liquid outlet 22, and a micro-nano bubbler accommodating chamber 23 disposed between the liquid inlet 21 and the liquid outlet 22. The micro-nano bubbler 1 is internally provided with a bubble liquid micro-channel 11, and the micro-nano bubbler 1 is arranged in the micro-nano bubbler accommodating cavity 23 and forms a gap water flowing channel 3 with the inner wall of the micro-nano bubbler accommodating cavity 23.
It should be noted that, the outer contours of the cross sections of the housing 2 and the micro-nano bubbler 1 in fig. 1 to 5 are all circular, but the present invention is not limited thereto, and may also be, for example, square, polygon, etc. (not shown in the figures), that is, the shapes of the housing 2 and the micro-nano bubbler 1 may be various. The micro-nano bubbler 1 in fig. 1 to 5 is cylindrical and does not directly contact with the inner wall of the micro-nano bubbler accommodating cavity 23, and an annular gap water flowing channel 3 is formed between the outer circumferential wall of the cylinder of the micro-nano bubbler 1 and the inner wall of the micro-nano bubbler accommodating cavity 23; the invention is not limited to this, and for example, the micro-nano bubbler 1 is in a cylindrical shape and is in sliding contact with one side of the inner wall of the micro-nano bubbler accommodating cavity 23, and an irregular gap water flow channel 3 (not shown in the figure) is formed between the outer circumferential wall of part of the cylindrical body of the micro-nano bubbler 1 and part of the inner wall of the micro-nano bubbler accommodating cavity 23, and of course, the formation manner of the gap water flow channel 3 may be various and may be changed according to the specific shapes of the housing portion 2 and the micro-nano bubbler 1 or the installation manner between the housing portion 2 and the micro-nano bubbler 1.
The micro-nano bubbler 1 can be switched between a first position for conducting the gap water flowing channel 3 and a second position for closing the gap water flowing channel 3. Namely, the micro-nano bubbler 1 can be movably arranged in the micro-nano bubbler accommodating cavity 23 and can be switched between a first position and a second position to conduct the gap water flowing channel 3 or close the gap water flowing channel 3. As shown in fig. 1 to 5, a top annular bearing surface 25 is formed on the inner wall of the micro-nano bubbler accommodating cavity 23, a step bottom surface 121 is formed on the micro-nano bubbler 1, and when the micro-nano bubbler 1 is at the first position, the top annular bearing surface 25 and the step bottom surface 121 are separated from each other to conduct the water gap flow channel 3; when the micro-nano bubbler 1 is at the second position, the top annular bearing platform surface 25 and the step bottom surface 121 are in contact with each other to close the water passing gap flow channel 3. Certainly, for example, the inner wall of the cavity of the micro-nano bubbler accommodating cavity 23 is an inverted cone-shaped surface, the outer peripheral wall of the micro-nano bubbler 1 is formed into an inverted cone-shaped surface (not shown in the figure) matched with the inverted cone-shaped inner wall of the micro-nano bubbler accommodating cavity 23, and when the micro-nano bubbler 1 is at the first position, the outer peripheral wall of the micro-nano bubbler 1 and the inner wall of the cavity of the micro-nano bubbler accommodating cavity 23 are separated from each other to conduct the water gap flow channel 3; when the micro-nano bubbler 1 is in the second position, the outer peripheral wall of the micro-nano bubbler 1 and the inner wall of the micro-nano bubbler accommodating cavity 23 are in contact with each other to close the water passing gap flow channel 3, that is, the micro-nano bubbler 1 can close the gap water passing channel 3 in various forms, which is not limited in the invention.
The micro-nano bubble former on the existing water outlet faucet forms micro-nano bubble water by applying a pressure release mode, the mode inevitably causes the water yield of the water outlet faucet to be too small, particularly the water yield under the condition of low water pressure is smaller, the normal water using requirements of users are seriously influenced, and the user experience is poorer.
Aiming at the pain point, the micro-nano bubble liquid generating device 100 is provided with a bubble liquid micro-channel 11 and a gap water channel 3 between a liquid inlet 21 and a liquid outlet 22, and when the liquid dissolved with gas in the liquid inlet 21 flows out through the bubble liquid micro-channel 11, the gas dissolved in the liquid is released in the liquid to form micro-nano bubble liquid; when feed liquor pressure is lower, the liquid of inlet 21 can flow to liquid outlet 22 from bubble liquid microchannel 11 and clearance water flow channel 3 simultaneously, has guaranteed micro-nano bubble liquid generating device 100's play water flow, satisfies user's normal water demand, promotes user's use satisfaction greatly.
Optionally, referring to fig. 1 to 5, the gap water flowing channel 3 may be an annular gap flowing channel formed between an outer wall of the micro-nano bubbler 1 and an inner wall of the micro-nano bubbler accommodating cavity 23. In order to ensure that the liquid in the liquid inlet 21 can smoothly flow from the gap water flow passage 3 to the liquid outlet 22 and ensure sufficient water outlet amount when the liquid inlet pressure is low, the minimum annular gap width of the gap water flow passage 3 is larger than the minimum diameter of the bubble liquid micro flow passage 11. Wherein, the minimum annular space width of clearance water flow channel 3 defines the minimum interval between the outer wall of micro-nano bubbler 1 and the cavity inner wall of micro-nano bubbler holding cavity 23, and bubble liquid micro-channel 11 can form the venturi tube structure, including contraction section, throat and diffusion section promptly, and the minimum diameter of bubble liquid micro-channel 11 defines the minimum circulation diameter of the throat of bubble liquid micro-channel 11.
Further, the micro-nano bubble liquid generating device 100 further comprises a current-limiting driving member 4 for driving the micro-nano bubbler 1 to move towards the first position. Specifically, as shown in fig. 1 to 5, the current-limiting driver 4 is a return spring, but the present invention is not limited thereto, and the current-limiting driver 4 may be in various forms such as an electromagnet type driver, a permanent magnet, and the like. As shown in fig. 1 to 5, the driving manner of the current-limiting driving member 4 is that the liquid inlet pressure of the liquid inlet drives the micro-nano bubbler 1 to move towards the second position and the elastic potential energy of the return spring drives the micro-nano bubbler 1 to move towards the first position, but the present invention is not limited thereto, and the driving manner of the current-limiting driving member 4 may also be, for example, an electromagnetic control reciprocating manner or a manual control reciprocating manner (not shown in the figures).
In some embodiments, the flow-limiting driving member 4 may be an elastic member, one end of the flow-limiting driving member 4 abuts against the housing portion 2 at the liquid outlet 22, and the other end is elastically biased on the micro-nano bubbler 1. Specifically, as shown in fig. 1 to 5, the flow-limiting driving member 4 is a return spring, a liquid outlet step 24 is formed between the liquid outlet 22 and the micro-nano bubbler accommodating cavity 23, one end of the flow-limiting driving member 4 abuts against the liquid outlet step 24, and the other end of the flow-limiting driving member is elastically biased on the step bottom surface 121 of the micro-nano bubbler 1. Of course, the current-limiting driving member 4 may also be biased to the bottom end surface 13 of the micro-nano bubbler 1 or other positions of the micro-nano bubbler 1, and the invention is not limited thereto. As shown in fig. 1 to 5, when the liquid inlet pressure is smaller than the compression force of the return spring, the micro-nano bubbler 1 is jacked up by the return spring, the step bottom 121 is separated from the top annular bearing platform 25, the liquid inlet of the liquid inlet 21 flows to the liquid outlet 22 from the bubble liquid micro-channel 11 and the gap water-passing channel 3, and at this time, the micro-nano bubble liquid generating device 100 has the same function as a common faucet; when the liquid inlet pressure is greater than the compression force of the return spring, the micro-nano bubbler 1 moves downwards, the return spring is compressed until the hydraulic pressure is large enough, the micro-nano bubbler 1 seals the gap water flowing channel 3, and liquid can only flow out through the bubble liquid micro-flowing channel 11. At the moment, gas dissolved in the liquid flows out of the bubble liquid micro-channel 11, and after pressure is released, micro-nano bubble water is formed and flows out.
In some embodiments, the flow-restricting driving member 4 may include a first magnetic member and a second magnetic member that are aligned and mutually repulsive, the first magnetic member is disposed on the housing portion 2 at the liquid outlet 22, and the other is disposed on an outer wall (not shown) of the micro-nano bubbler 1 above the first magnetic member. The driving mode of the current-limiting driving part 4 is that the liquid inlet pressure of the liquid inlet drives the micro-nano bubbler 1 to move towards the second position, and the repulsive force between the first magnetic part and the second magnetic part drives the micro-nano bubbler 1 to move towards the first position. When the liquid inlet pressure is smaller than the repulsive force of the first magnetic part and the second magnetic part, the step bottom surface 121 is separated from the top annular bearing platform surface 25, liquid inlet of the liquid inlet 21 flows to the liquid outlet 22 from the bubble liquid micro-channel 11 and the gap water flowing channel 3, and at the moment, the micro-nano bubble liquid generating device 100 has the same function as a common faucet; when the liquid inlet pressure is larger than the repulsive force of the first magnetic part and the second magnetic part, the micro-nano bubbler 1 moves downwards until the hydraulic pressure is large enough, the step bottom surface 121 is in contact with the top annular bearing platform surface 25, the micro-nano bubbler 1 seals the gap water flowing channel 3, and liquid can only flow out through the bubble liquid micro-flowing channel 11. At the moment, gas dissolved in the liquid flows out of the bubble liquid micro-channel 11, and after pressure is released, micro-nano bubble water is formed and flows out.
Optionally, in order to enable the micro-nano bubbler 1 to close the gap water flowing channel 3 at the second position, the outer wall of the micro-nano bubbler 1 and the inner wall of the micro-nano bubbler accommodating cavity 23 form a ring surface sealing contact of the closed gap water flowing channel 3.
Specifically, as shown in fig. 1 to 5, an annular limiting bearing platform portion may protrude inward from the inner wall of the micro-nano bubbler accommodating cavity 23, the limiting bearing platform portion includes a top annular bearing platform 25 facing the liquid inlet 21, the micro-nano bubbler 1 is columnar and includes a top liquid inlet end facing the liquid inlet 21 and a bottom liquid outlet end facing the liquid outlet 22, the top liquid inlet end is formed with an expanding portion 12, and a step bottom surface 121 of the expanding portion 12 and the top annular bearing platform 25 form a ring surface in a sealing contact at a second position. It should be noted that a position relatively close to the central axis of the micro-nano bubbler 1 is defined as "inside", and a position relatively far away from the central axis of the micro-nano bubbler 1 is defined as "outside".
Of course, the torus sealing contact may also be formed in other manners, for example, a sealing conical surface flaring toward the liquid inlet 21 is formed on the inner wall of the micro-nano bubbler accommodating cavity 23, and the peripheral wall of the liquid inlet end at the top of the micro-nano bubbler 1 forms a torus sealing contact with the sealing conical surface at a second position (not shown in the figure). Or, for example, a liquid outlet step 24 is formed between the liquid outlet 22 and the micro-nano bubbler accommodating cavity 23, and in the second position, the bottom end surface 13 of the bottom liquid outlet end of the micro-nano bubbler 1 abuts against the liquid outlet step 24 to form a ring surface sealing contact (not shown in the figure).
Further, as shown in fig. 1 to 5, in order to improve the sealing performance of the gap water flow channel 3 at the first position, the micro-nano bubble liquid generating device 100 may further include an annular sealing member 5, and the annular sealing member 5 is embedded on the inner wall of the micro-nano bubbler accommodating cavity 23 and/or the outer wall of the micro-nano bubbler 1, which form a toroidal sealing contact.

Therefore, when the liquid dissolved with gas in the liquid inlet flows out through the bubble liquid micro-channel 11, the gas dissolved in the liquid is released from the liquid to form micro-nano bubble liquid. Wherein, the water inlet angle and the water outlet angle of the bubble liquid micro-channel 11 can be improved according to the actual requirement; the minimum diameter of the bubble liquid micro flow channel 11 can be designed with different parameters as required.
