[0017] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solutions and their preferred embodiments of the present invention have the following beneficial effects due to the following technical means:

[0018] 1. In Solution One and its preferred embodiments, a bubble water member includes a water passage body, and the water passage body is provided with a first Venturi water channel and a second Venturi water channel that pass water in sequence; it is also provided with a first air hole and a second air hole;

[0019] The first air hole is communicated with the negative pressure area of the first Venturi water channel, so that when the first Venturi water channel passes water, gas enters the first Venturi water channel to form a gas-water mixture;

[0020] The second air inlet is connected to the negative pressure area of ​​the second venturi water channel, so that when the water passes through the second venturi water channel, the gas enters the second venturi water channel to form a gas-water mixture again; the minimum cross-sectional area of ​​the second venturi water channel is smaller than the minimum cross-sectional area of ​​the first venturi water channel, so the gas-water mixture output by the first venturi water channel can be further refined to form a gas-water mixture with a smaller particle size. Compared with multiple filters or porous media stacked in sequence, it is not easy to be blocked and does not require pressurization.

[0021] 2. In scheme 2 and its preferred embodiment, there are several first air inlet holes, and each first air inlet hole is connected to the negative pressure area of ​​the first Venturi water channel to increase the air intake volume and make the gas and water mix more evenly.

[0022] 3. In scheme three and its preferred embodiments, if the first air inlet hole is directly opened on the outer surface, the appearance of the bubble water part is rather ugly. A first air inlet port and a first air inlet cavity are also provided through the water-permeable body. The first air inlet port is opened on the outer surface of the water-permeable body, and the first air inlet cavity connects the first air inlet port and the first air inlets. Air intake is achieved through one first air inlet port or a first air inlet port that is less in number than the first air inlets. The first air inlet cavity connects the first air inlet port and the first air inlet holes, which can increase the aesthetics.

[0023] 4. In scheme 4 and its preferred embodiment, the number of second Venturi water channels is several, the number of second air inlets is the same as the number of second Venturi water channels, and they are connected one by one. By setting more second Venturi water channels, the water flow is guaranteed. At the same time, each second Venturi water channel can fully accelerate the water flow and mix the gas.

[0024] 5. In the fifth scheme and its preferred embodiment, the water body also includes a third Venturi water channel, which is connected to the water outlet of the water passage cavity, and each second Venturi water channel is arranged around the third Venturi water channel, so as to reasonably utilize the space and increase the water flow. The minimum cross-sectional area of ​​the third Venturi water channel is smaller than the minimum cross-sectional area of ​​the first Venturi water channel, so as to further accelerate the water flow, facilitate the subsequent water discharge or further break up the water flow. And the water flow in the third Venturi water channel, as the main water outlet of the water channel at this level, plays a role in stabilizing the overall water flow direction. The water flow in the second Venturi water channel contains air, which is easily dragged by the water flow in the third Venturi water channel and moves closer to the center of the overall channel, avoiding the impact on the external wall to reduce the flow rate and the merging of bubbles.

[0025] 6. In the sixth scheme and its preferred embodiment, the water body is further provided with a second air inlet and a second air inlet cavity, the second air inlet is opened on the outer surface of the water body, and the second air inlet cavity is connected to the second air inlet and each second air inlet hole. Air intake is achieved through one second air inlet or a second air inlet with a smaller number than the second air inlet holes, and the second air inlet cavity achieves the connection between the first air inlet and the first air inlet hole, which can increase the aesthetics.

[0026] 7. In Solution VII and its preferred embodiments, the central axis of each second Venturi water channel is parallel to the central axis of the first Venturi water channel and is also parallel to the central axis of the next-level water channel. Since the water flow in the second Venturi water channel is not coaxial with the first Venturi water channel and the next-level water channel, after the water flow flows out of the second Venturi water channel, affected by the drag of the water flow in the third Venturi water channel and its own gas content, the flow becomes unstable and oscillates. After the oscillation effect reaches "equilibrium", it will cause the overall water flow to rotate around the axis of the third Venturi water channel. When the swirl occurs, the bubbles in the water flow will be subjected to the lateral shear force generated by the water flow on them, thereby further dividing the bubbles and reducing the bubble diameter.

[0027] 8. In Solution VIII and its preferred embodiments, the first microporous member is installed in the water passing cavity. The first microporous member has a plurality of micropores to further make the water particles smaller and increase the fineness of the gas-water mixture.

[0028] 9. In Solution IX and its preferred embodiments, the ultrasonic member is fixedly connected to the water passing body. The ultrasonic member is provided with an ultrasonic cavity communicating with the water outlet end of the second Venturi water channel. The ultrasonic member is adapted to ultrasonically vibrate the water in the ultrasonic cavity to further increase the fineness of the gas-water mixture.

[0029] 10. In Solution X and its preferred embodiments, the water outlet head is fixedly connected to the ultrasonic member. The water outlet head is provided with a water outlet channel. The water outlet channel communicates with the water outlet end of the ultrasonic cavity. The second microporous member is placed in the water outlet channel. The second microporous member has a plurality of micropores to further make the water particles smaller and further increase the fineness of the gas-water mixture. Description of the Drawings

[0045] Reference Figures 1 - 7 , a bubble water component, comprising a water passing body 1, an ultrasonic component 2, a water outlet head 3, a first microporous component 4 and a second microporous component 5.

[0046] The water passing body 1 is provided with a water inlet 11, a first Venturi water channel 12 (in other embodiments, the water inlet end of the first Venturi water channel 12 can be directly used as the water inlet 11), a water passing cavity 13 and a second Venturi water channel 14 / a third Venturi water channel 15 for passing water in sequence; the water passing body 1 is further provided with a first air inlet hole 161, a second air inlet hole 171, a first air inlet 163, a first air inlet cavity 162, a second air inlet 173 and a second air inlet cavity 172.

[0047] Reference Figure 3 , the first Venturi water channel 12 includes a first tapered section 121, a first air inlet section 122 and a first enlarged section 123 for passing water in sequence. Along the water passing direction of the first Venturi water channel 12, the water passing area of the first tapered section 121 gradually decreases, and the water passing area of the first enlarged section 123 gradually increases.

[0048] Reference Figure 5 , the first air inlet hole 161 is communicated with the negative pressure area of the first Venturi water channel 12, so that when water passes through the first Venturi water channel 12, gas enters the first Venturi water channel 12; the negative pressure area refers to the position where the water flow is accelerated by the structure of the first Venturi water channel 12, its speed is greater than the initial speed, and sufficient negative pressure can be generated to allow the first air inlet hole 161 to intake air. Usually, it is located at the end of the first tapered section 121 or the first air inlet section 122, where the acceleration is the most sufficient and the generated negative pressure is the largest. In this embodiment, the first air inlet hole 161 is communicated with the first air inlet section 122.

[0049] In this embodiment, the number of the first air inlet holes 161 is several, each first air inlet hole 161 is communicated with the negative pressure area of the first Venturi water channel 12, and each first air inlet hole 161 is arranged around an axis, and the air intake direction points to the axis.

[0050] The first air inlet 163 is formed on the outer surface of the water passage body 1. The first air inlet cavity 162 is annular and communicates with the first air inlet 163 and each first air inlet hole 161. When water flows through the first Venturi water channel 12, a negative pressure is generated at the first air intake section 122. The gas is sucked in from the first air inlet 163, and after passing through the first air inlet cavity 162 and the first air inlet hole 161 in sequence, it enters the first Venturi water channel 12.

[0051] Reference Figure 7 , the second Venturi water channel 14 includes a second tapered section 141, a second air intake section 142, and a second expanding section 143 through which water flows in sequence. Along the water flow direction of the second Venturi water channel 14, the water passing area of the second tapered section 141 gradually decreases, and the water passing area of the second expanding section 143 gradually increases. The minimum cross-sectional area of the second Venturi water channel 14 is smaller than the minimum cross-sectional area of the first Venturi water channel 12. In this embodiment, the end size of the second tapered section 141 is smaller than the end size of the first tapered section 121, so that the acceleration is more obvious, the negative pressure is greater, the gas-water mixing degree is higher, and the granularity is increased. The number of the second Venturi water channels 14 is several. And the central axis of each second Venturi water channel 14 is parallel to the central axis of the first Venturi water channel 12.

[0052] Reference Figure 3 , the third Venturi water channel 15 includes a third tapered section 151 and a third expanding section 152 through which water flows in sequence. Reference Figure 4 , the third Venturi water channel 15 communicates with the water outlet end of the water passage cavity 13. Each second Venturi water channel 14 is arranged around the third Venturi water channel 15. Similarly, the minimum cross-sectional area of the third Venturi water channel 15 is smaller than the minimum cross-sectional area of the first Venturi water channel 12.

[0053] Reference Figure 6 , the second air inlet hole 171 communicates with the negative pressure area of the second Venturi water channel 14, so that when water flows through the second Venturi water channel 14, gas enters the second Venturi water channel 14. Specifically, the second air inlet hole 171 communicates with the second air intake section 142 of the second Venturi water channel 14.

[0054] The number of the second air inlet holes 171 is the same as the number of the second Venturi water channels 14 and they are connected in one-to-one correspondence.

[0055] The second air inlet 173 is formed on the outer surface of the water passage body 1. The second air inlet cavity 172 is annular and communicates with the second air inlet 173 and each second air inlet hole 171. When water flows through the second Venturi water channel 14, a negative pressure is generated at the second air intake section 142. The gas is sucked in from the second air inlet 173, and after passing through the second air inlet cavity 172 and the second air inlet hole 171 in sequence, it enters the second Venturi water channel 14.

[0056] Reference Figure 3, the first microporous member 4 is installed in the water passage cavity 13. The first microporous member 4 has a plurality of micropores to further make the water particles smaller. The first microporous member 4 can be, but is not limited to, porous materials such as metal mesh, porous ceramics, and metal foam.

[0057] For ease of processing, the water passage body 1 can be formed by assembling two components. One component is provided with a first Venturi water channel 12, a first air inlet hole 161, a first air inlet cavity 162, and a first air inlet port 163; the other part is provided with a second Venturi water channel 14, a second air inlet hole 171, a second air inlet cavity 172, a second air inlet port 173, and a third Venturi water channel 15.

[0058] Reference Figure 3 , the ultrasonic member 2 is fixedly connected to the water passage body 1. In this embodiment, the ultrasonic member 2 is threadedly connected to the water passage body 1. The ultrasonic member 2 is provided with an ultrasonic cavity 21 communicating with the water outlet end of the second Venturi water channel 14. The ultrasonic member 2 is adapted to ultrasonically vibrate the water in the ultrasonic cavity 21. Among them, the ultrasonic member 2 is an instrument that generates vibrations using ultrasonic frequencies.

[0059] The water outlet head 3 is fixedly connected to the ultrasonic member 2. In this embodiment, the ultrasonic member 2 is connected to the water outlet head 3 through an adapter.

[0060] The water outlet head 3 is provided with a water outlet channel 31, and the water outlet channel 31 communicates with the water outlet end of the ultrasonic cavity 21.

[0061] The second microporous member 5 is placed in the water outlet channel 31. The second microporous member 5 has a plurality of micropores to further make the water particles smaller. The second microporous member 5 can be, but is not limited to, porous materials such as metal mesh, porous ceramics, and metal foam. Working principle:

[0062] Reference Figure 3 , water enters from the water inlet 11, passes through the first Venturi water channel 12, and the speed increases to form a negative pressure area. The negative pressure area sucks air to form an air-water mixture;

[0063] Then it is cut by the first microporous member 4 to further generate microbubble water, and then enters the second Venturi water channel 14 and performs an air intake action to refine the particle size of the microbubble water.

[0064] Since the central axis of the second Venturi water channel 14 is misaligned with the central axis of the first Venturi water channel 12 and the central axis of the next-level water channel (ultrasonic cavity 21), after the water flow flows out of the second Venturi water channel 14, affected by the water flow drag of the third Venturi water channel 15 and its own gas content, the flow becomes unstable and oscillates. After the oscillation effect reaches "equilibrium", it will cause the overall water flow to rotate around the axis of the third Venturi water channel 15. When the swirl occurs, the bubbles in the water flow will be subjected to the lateral shear force generated by the water flow on them, thereby further dividing the bubbles and reducing the bubble particle size.

[0065] Then it continues to enter the ultrasonic cavity 21, and the ultrasonic component 2 ultrasonically vibrates the water in the ultrasonic cavity 21. The ultrasonic vibration promotes the generation of microbubbles and the refinement of the particle size. Then it passes through the second microporous component 5, and finally the microbubble water flow flows out from the water outlet channel 31.

[0066] Compared with the prior art, the present embodiment has the following beneficial effects:

[0067] In an exemplary embodiment, a bubble water component includes a water passing body 1. The water passing body 1 is provided with a first Venturi water channel 12 and a second Venturi water channel 14 that pass water in sequence; it is also provided with a first air inlet hole 161 and a second air inlet hole 171;

[0068] The first air inlet hole 161 is communicated with the negative pressure area of the first Venturi water channel 12, so that when the first Venturi water channel 12 passes water, gas enters the first Venturi water channel 12 to form a gas-water mixture;

[0069] The second air inlet hole 171 is communicated with the negative pressure area of the second Venturi water channel 14, so that when the second Venturi water channel 14 passes water, gas enters the second Venturi water channel 14 to form a gas-water mixture again; the minimum cross-sectional area of the second Venturi water channel 14 is smaller than the minimum cross-sectional area of the first Venturi water channel 12. Therefore, the gas-water mixture output by the first Venturi water channel 12 can be further refined to form a gas-water mixture with a smaller particle size. Compared with multiple stacked filter meshes or porous media, it is not easy to be blocked and does not require pressurization.

[0070] In an exemplary embodiment, the number of the first air inlet holes 161 is several, and each first air inlet hole 161 is communicated with the negative pressure area of the first Venturi water channel 12, increasing the air intake amount and making the mixing of gas and water more uniform.

[0071] In an exemplary embodiment, if the first air inlet holes 161 are directly opened on the outer surface, the appearance of the bubble water component is relatively ugly. The water passing body 1 is also provided with a first air inlet 163 and a first air inlet cavity 162. The first air inlet 163 is opened on the outer surface of the water passing body 1, and the first air inlet cavity 162 communicates the first air inlet 163 and each first air inlet hole 161. Intake air is achieved through one first air inlet 163 or a smaller number of first air inlets 163 than the number of the first air inlet holes 161. The first air inlet cavity 162 realizes the connection between the first air inlet 163 and the first air inlet holes 161, which can increase the aesthetic degree.

[0072] In an exemplary embodiment, the number of the second Venturi water channels 14 is several, and the number of the second air inlet holes 171 is the same as the number of the second Venturi water channels 14 and is in one-to-one correspondence connection. By providing more second Venturi water channels 14, the water passing amount is guaranteed. At the same time, each second Venturi water channel 14 can fully accelerate the water flow and mix the gas.

[0073] In an exemplary embodiment, the water passage body further includes a third Venturi water channel 15, which is communicated with the water outlet end of the water passage cavity 13. Each second Venturi water channel 14 is arranged around the third Venturi water channel 15, so as to make reasonable use of space and increase the water flow rate. The minimum cross-sectional area of the third Venturi water channel 15 is smaller than that of the first Venturi water channel 12, so as to further accelerate the water flow, facilitate subsequent water outlet or further break up the water flow. And the water flow in the third Venturi water channel 15, as the main water outlet of this stage of water channel, plays a role in stabilizing the overall water flow direction. The water flow in the second Venturi water channel 14 contains gas and is easily dragged by the water flow in the third Venturi water channel 15 to move closer to the center of the overall channel, avoiding the reduction of the flow rate due to the impact on the outer wall surface and the merging of bubbles.

[0074] In an exemplary embodiment, the water passage body is further provided with a second air inlet 173 and a second air inlet cavity 172. The second air inlet 173 is opened on the outer surface of the water passage body 1, and the second air inlet cavity 172 communicates the second air inlet 173 with each second air inlet hole 171. Intake air is realized through one second air inlet 173 or a second air inlet 173 with a smaller number than that of the second air inlet holes 171, and the second air inlet cavity 172 realizes the communication between the first air inlet 163 and the first air inlet holes 161, which can increase the aesthetic degree.

[0075] In an exemplary embodiment, the central axis of each second Venturi water channel 14 is parallel to the central axis of the first Venturi water channel 12 and is also parallel to the central axis of the next stage of water channel. Since the water flow in the second Venturi water channel 14 is not coaxial with the first Venturi water channel 12 and the next stage of water channel, after the water flow flows out of the second Venturi water channel 14, affected by the drag of the water flow in the third Venturi water channel 15 and its own gas content, the flow becomes unstable and oscillates. After the oscillation effect reaches "equilibrium", it will cause the overall water flow to rotate around the axis of the third Venturi water channel 15. When the swirl occurs, the bubbles in the water flow will be subjected to the lateral shear force generated by the water flow on them, thereby further dividing the bubbles and reducing the bubble diameter.

[0076] In an exemplary embodiment, the first microporous member 4 is installed in the water passage cavity 13, and the first microporous member 4 has a plurality of micropores to further make the water particles smaller and increase the fineness of the air-water mixture.

[0077] In an exemplary embodiment, the ultrasonic member 2 is fixedly connected to the water passage body 1. The ultrasonic member 2 is provided with an ultrasonic cavity 21 communicated with the water outlet end of the second Venturi water channel 14, and the ultrasonic member 2 is adapted to ultrasonically vibrate the water in the ultrasonic cavity 21 to further increase the fineness of the air-water mixture.

[0078] In an exemplary embodiment, the water outlet head 3 is fixedly connected to the ultrasonic component 2. The water outlet head 3 is provided with a water outlet channel 31, and the water outlet channel 31 is communicated with the water outlet end of the ultrasonic cavity 21. The second microporous component 5 is placed in the water outlet channel 31, and the second microporous component 5 has a plurality of micropores to further make the water particles smaller and further increase the fineness of the air-water mixture.
