Description

Technical Field

[0001] The present invention relates to the technical field of bubble water machines, and particularly to a flow stabilizer and a bubble water machine. Background Art

[0002] Drinkable bubble water is a beverage obtained by dissolving food-grade carbon dioxide in drinking water. Currently, most bubble water machines on the market have the problems that the carbon dioxide gas and water are not fully mixed, and the solubility of carbon dioxide gas in water is low. Summary of the Invention

[0003] The main object of the present invention is to propose a flow stabilizer, aiming to improve the solubility of carbon dioxide gas in water.

[0004] To achieve the above object, the flow stabilizer proposed by the present invention is used for a bubble water machine, and the flow stabilizer includes:

[0005] A flow stabilizing shell provided with an installation cavity, a water inlet and a water outlet; and

[0006] A flow stabilizing member disposed in the installation cavity to form a spiral flow channel between the flow stabilizing shell and the flow stabilizing member, and the water inlet and the water outlet are respectively communicated with the spiral flow channel.

[0007] In an embodiment, a spiral groove is provided on the outer peripheral surface of the flow stabilizing member, and the outer peripheral surface of the flow stabilizing member is in sealing fit with the cavity wall of the installation cavity to form the spiral flow channel between the spiral groove and the flow stabilizing shell.

[0008] In an embodiment, the groove depth H of the spiral groove ranges from 2 mm to 5 mm, and the groove opening width W of the spiral groove ranges from 1 mm to 3 mm.

[0009] In an embodiment, the flow stabilizing member includes a guiding cap and a flow stabilizing column connected to each other, and the guiding cap is disposed close to the water inlet.

[0010] In an embodiment, the length L of the flow stabilizing column ranges from 20 mm to 40 mm, and the spiral pitch X of the spiral flow channel ranges from 3 mm to 7 mm.

[0011] In an embodiment, the guiding cap is arranged in a conical or pyramidal shape.

[0012] In an embodiment, the included angle α between the outer peripheral surface of the guiding cap and the extension line of the outer peripheral surface of the flow stabilizing member ranges from 30° to 60°.

[0013] In an embodiment, the installation cavity has a guiding section corresponding to the guiding cap, and the guiding section is arranged to be gradually expanded in the direction close to the water outlet.

[0014] In one embodiment, a limiting post is provided at one end of the flow stabilizer near the water outlet, so as to form an expansion cavity between the limiting post and the flow stabilizer housing, and the expansion cavity is communicated with the water outlet and the spiral flow channel respectively.

[0015] In one embodiment, the radial cross-section of the spiral flow channel is triangular, circular, square or diamond-shaped.

[0016] In one embodiment, the flow stabilizer is provided with a flow stabilizer cover detachably connected to the flow stabilizer housing to cover the installation cavity.

[0017] In one embodiment, the water inlet is formed on the flow stabilizer cover.

[0018] In one embodiment, the flow stabilizer housing includes a first section and a second section arranged at an angle and communicated with each other. The installation cavity is formed in the first section. The flow stabilizer cover covers one end of the first section away from the second section, and the water outlet is formed at one end of the second section away from the first section.

[0019] In one embodiment, the flow stabilizer further includes a bubbler detachably and sealingly connected to the flow stabilizer housing, and the water outlet is formed at one end of the water outlet flow channel of the bubbler away from the flow stabilizer.

[0020] In one embodiment, a first bubbling net and a second bubbling net are arranged at intervals in the direction close to the water outlet of the water outlet flow channel, and the pore diameter of the first bubbling net is smaller than that of the second bubbling net.

[0021] In one embodiment, the pore diameter range of the first bubbling net is 0.1 mm to 0.3 mm, and the pore diameter range of the second bubbling net is 0.8 mm to 1.1 mm.

[0022] The present invention also provides a bubble water machine, including the above-mentioned flow stabilizer.

[0023] The technical solution of the present invention is to set an installation cavity, a water inlet and a water outlet on the flow stabilizer housing; and arrange the flow stabilizer in the installation cavity to form a spiral flow channel between the flow stabilizer housing and the flow stabilizer. The water inlet and the water outlet are respectively communicated with the spiral flow channel. In this way, when bubble water flows into the flow stabilizer, due to the design of the spiral flow channel, the cross-sectional area of the bubble water flow path becomes smaller, so that the flow rate of the bubble water increases during the flow in the spiral flow channel, and the flow resistance between the booster pump and the flow stabilizer in the bubble water machine increases, making the pressure of the flow path larger, and further achieving the purpose of improving the dissolution ability of carbon dioxide gas.

[0024] Secondly, in this solution, a spiral flow channel is arranged in the flow stabilizer for the bubble water to flow through. When the bubble water flows through the spiral flow channel, the centrifugal force generated by the spiral flow channel forces the liquid to rotate along the wall surface, so that a high-pressure area will be formed on the wall surface of the spiral flow channel, resulting in excessive local pressure on the wall surface, thereby reducing the flow rate of the bubble water, and then the effect of flow stabilization can be achieved. And a low-pressure area is formed in the central area, promoting the efficient entrainment and dissolution of carbon dioxide gas. Moreover, the spiral flow channel can extend the residence time of the bubble water in the flow stabilizer, enabling the carbon dioxide gas and the water to be fully mixed before entering the water outlet, reducing the escape of undissolved gas, and improving the taste and stability of the bubble water.

[0040] Drinkable sparkling water is a beverage obtained by dissolving food-grade carbon dioxide in drinking water. Currently, most sparkling water machines on the market have the problems that the carbon dioxide gas and water are not fully mixed and the solubility of the gas in water is low.

[0041] To solve the above problems, the present invention provides a flow stabilizer 10.

[0042] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 7 , in an embodiment of the present invention, the flow stabilizer 10 is used for a sparkling water machine. The flow stabilizer 10 includes a flow stabilizing housing 100 and a flow stabilizing member 200. The flow stabilizing housing 100 is provided with an installation cavity 110, a water inlet 120, and a water outlet 130. The flow stabilizing member 200 is disposed in the installation cavity 110 to form a spiral flow channel 300 between the flow stabilizing housing 100 and the flow stabilizing member 200. The water inlet 120 and the water outlet 130 are respectively communicated with the spiral flow channel 300.

[0043] In this embodiment, the sparkling water machine of the present solution includes a filtration module, a cold water tank, a refrigeration system, a booster pump, an over-current carbonator, a carbon dioxide gas cylinder, and a Venturi structure. Due to the setting of the filtration module, the sparkling water machine of the present solution can be directly connected to a tap water pipeline. Of course, the sparkling water machine proposed in the present solution can also be connected to pipelines of bottled water, filtered water, purified water, etc.

[0044] Taking the connection to the tap water pipeline as an example, under the pressure of tap water, the water flow can meet the drinking water requirements after passing through the filtration module. The filtered water enters the cold water tank, and the refrigeration system operates to provide cooling capacity to continuously cool the normal temperature water. After reaching the specified temperature (usually 4°C, and of course it can also be 6°C, 2°C, 3°C, etc.), the refrigeration stops. Then, the cold water is pumped by the booster pump, and the pressurized cold water enters the nozzle liquid inlet of the over-current carbonator. At the same time, the high-pressure carbon dioxide gas in the carbon dioxide gas cylinder enters the gas inlet of the over-current carbonator under the control of the solenoid valve. The gas-liquid two-phase (carbon dioxide gas and cold water) enters simultaneously. The high-speed cold water generates a certain negative pressure through the Venturi structure, sucking in the gas and completing efficient atomization with the cold water. Subsequently, the carbon dioxide gas dissolution and carbonization process is completed in the turbulence cavity of the over-current carbonator to generate sparkling water. Then, the sparkling water enters the flow stabilizer 10 proposed in the present solution and flows out of the sparkling water machine through the flow stabilizer 10.

[0045] The flow stabilizer 10 of the present invention is provided with an installation cavity 110, a water inlet 120, and a water outlet 130 on the flow stabilizing shell 100; and a flow stabilizing member 200 is disposed in the installation cavity 110 to form a spiral flow channel 300 between the flow stabilizing shell 100 and the flow stabilizing member 200. The water inlet 120 and the water outlet 130 are respectively communicated with the spiral flow channel 300. When the bubble water flows into the flow stabilizer 10, due to the design of the spiral flow channel 300, the cross-sectional area of the bubble water flow path becomes smaller, so that the flow velocity of the bubble water increases during the flow in the spiral flow channel 300, and the flow resistance between the booster pump and the flow stabilizer 10 in the bubble water machine increases, making the pressure of the flow path larger, thereby achieving the purpose of improving the dissolution ability of carbon dioxide gas.

[0046] Secondly, a spiral flow channel 300 is provided in the flow stabilizer 10 for the bubble water to flow through. When the bubble water flows through the spiral flow channel 300, the centrifugal force generated by the spiral flow channel 300 forces the liquid to rotate along the wall surface, so that a high-pressure area will be formed on the wall surface of the spiral flow channel 300, making the local pressure on the wall surface too large, thereby reducing the flow velocity of the bubble water, and then the effect of flow stabilization can be achieved. And a low-pressure area is formed in the central area, promoting the efficient entrainment and dissolution of carbon dioxide gas. Moreover, the spiral flow channel 300 can extend the residence time of the bubble water in the flow stabilizer 10, so that the carbon dioxide gas and the water are fully mixed before entering the water outlet 130, reducing the escape of undissolved gas and improving the taste and stability of the bubble water.

[0047] Refer to Figure 2 、 Figure 3 、 Figure 5 and Figure 6, optionally, a spiral groove 210 is provided on the outer peripheral surface of the flow stabilizer 200, and the outer peripheral surface of the flow stabilizer 200 is in sealed fit with the cavity wall of the installation cavity 110 to form the spiral flow channel 300 between the spiral groove 210 and the flow stabilizer housing 100; it can be understood that by setting the spiral groove 210 on the outer peripheral surface of the flow stabilizer 200, the spiral groove 210 can be directly processed by traditional turning, milling and other processes during processing, without complex inner cavity processing technology, significantly reducing production costs and time. Moreover, the exposed spiral groove 210 is convenient for daily inspection, cleaning or repair. Of course, this solution is not limited to this. In the second embodiment, a spiral groove can also be provided on the inner cavity wall of the installation cavity 110, and the outer peripheral surface of the flow stabilizer 200 is in sealed fit with the cavity wall of the installation cavity 110, so that the spiral flow channel 300 can also be formed between the spiral groove and the flow stabilizer 200. Of course, this solution is not limited to this. In the third embodiment, a spiral groove 210 can also be provided on the outer peripheral surface of the flow stabilizer 200, a spiral groove is provided on the inner cavity wall of the installation cavity 110, and the outer peripheral surface of the flow stabilizer 200 is in sealed fit with the cavity wall of the installation cavity 110, so that the spiral flow channel 300 can also be formed between the spiral groove 210 and the spiral groove. Of course, this solution is not limited to this. In the fourth embodiment, a spiral groove 210 can also be provided on the outer peripheral surface of the flow stabilizer 200, a spiral groove is provided on the inner cavity wall of the installation cavity 110, the outer peripheral surface of the flow stabilizer 200 is in sealed fit with the cavity wall of the installation cavity 110, the spiral groove 210 and the spiral groove are arranged in a staggered manner, the spiral flow channel 300 is formed between the spiral groove 210 and the cavity wall of the installation cavity 110, and the spiral flow channel 300 is formed between the spiral groove and the outer peripheral surface of the flow stabilizer 200.

[0048] Further, in this embodiment, the flow stabilizer 200 is in interference fit with the flow stabilizer housing 100. It can be understood that the frictional force and stress generated by the interference fit can withstand a large load, so that the flow stabilizer 200 is not easily loosened in the flow stabilizer housing 100. Moreover, the interference fit can ensure the position accuracy between parts, reduce the probability of relative movement of the flow stabilizer 200, and thus reduce the error caused by relative movement. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer 200 can also be screwed to the flow stabilizer housing 100, and the outer peripheral surface of the flow stabilizer 200 is in sealed fit with the cavity wall of the installation cavity 110.

[0049] Refer to Figure 2 and Figure 5 , optionally, the groove depth H of the spiral groove 210 ranges from 2 mm to 5 mm, and the groove width W of the spiral groove 210 ranges from 1 mm to 3 mm.

[0050] It can be understood that if H is greater than 5 mm, the groove depth of the spiral groove 210 is too deep, which will increase the processing difficulty of the spiral groove 210. If H is less than 2 mm, the groove depth of the spiral groove 210 is too small, so the channel for the bubble water to rotate and flow is relatively shallow, and the centrifugal force of the bubble water is small, resulting in poor flow stabilization effect. In this solution, the groove depth of the spiral groove 210 is limited between 2 mm and 5 mm, that is, 2 mm ≤ H ≤ 5 mm. This is beneficial for providing a larger space for the fluid to rotate, enhancing the centrifugal force of the bubble water, forcing the bubble water to rotate along the wall surface, which is conducive to forming a high-pressure area on the wall surface of the spiral flow channel 300, making the local pressure on the wall surface too large, so that the flow rate of the bubble water decreases, and then achieving the effect of flow stabilization.

[0051] Secondly, if W is less than 1 mm, the groove width of the spiral groove 210 is small, which is not only inconvenient for processing but also prone to blockage. If W is greater than 3 mm, the groove width of the spiral groove 210 is large, so it cannot achieve a good flow limiting effect, which will reduce the carbon dioxide gas dissolution ability. In this solution, the groove width W of the spiral groove 210 is limited between 1 mm and 3 mm, that is, 1 mm ≤ W ≤ 3 mm. This can limit the flow rate of the bubble water, and then increase the flow path resistance between the booster pump and the flow stabilizer 10 in the bubble water machine, making the pressure of the flow path larger, and then achieving the purpose of improving the carbon dioxide gas dissolution ability. At the same time, it can also reduce the risk of blockage of the spiral groove 210.

[0052] Among them, in this solution, the groove depth of the spiral groove 210 is limited between 2 mm and 5 mm, and the groove width W of the spiral groove 210 is limited between 1 mm and 3 mm. This is beneficial to improve the flow stabilization effect while enhancing the carbon dioxide gas dissolution ability.

[0053] Optionally, the flow stabilizer 200 includes a connecting flow guiding cap 220 and a flow stabilizing column 230. The flow guiding cap 220 is arranged close to the water inlet 120. It can be understood that the flow guiding cap 220 is arranged to gradually expand in the direction close to the flow stabilizing column 230, that is, the cross-section of the flow guiding cap 220 in the radial direction gradually increases in the direction close to the flow stabilizing column 230. The setting of the flow guiding cap 220 can not only reduce the local pressure loss at the end face of the flow stabilizing column 230, but also help to rectify the flow immediately when the bubble water enters the flow stabilizer 10, improving the overall stability. Moreover, through the guidance of the flow guiding cap 220, the water flow forms a stable axial flow before entering the flow stabilizing column 230, reducing secondary flow and vortices, and enhancing the subsequent flow stabilization effect. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer 200 can also be integrally in the shape of a flow stabilizing column without setting a flow guiding cap.

[0054] Optionally, the length L of the flow stabilizing column 230 ranges from 20 mm to 40 mm, and the spiral pitch X of the spiral flow channel 300 ranges from 3 mm to 7 mm.

[0055] It can be understood that if the length L of the steady flow column 230 is less than 20 mm, the length of the steady flow column 230 is too short, which will result in a shorter set length of the spiral flow channel 300 and insufficient rectification effect; if the length L of the steady flow column 230 is greater than 20 mm, the length of the steady flow column 230 is too long, which will overly extend the residence time of the bubble water. Although the rectification effect can be enhanced, the pressure drop will also increase. In this solution, the length L range of the steady flow column 230 is limited between 20 mm and 40 mm, that is, 20 mm ≤ L ≤ 40 mm, so as to increase the residence time of the bubble water and enhance the rectification effect.

[0056] Secondly, if the spiral pitch X of the spiral flow channel 300 is less than 3 mm, the spiral flow channel 300 will be too dense, resulting in a small wall strength of the spiral flow channel 300. If the spiral pitch X of the spiral flow channel 300 is greater than 7 mm, the spiral pitch of the spiral flow channel 300 will be large, and the large pitch may reduce the resistance, thereby reducing the dissolution ability of carbon dioxide. In this solution, the spiral pitch X range of the spiral flow channel 300 is limited between 3 mm and 7 mm, that is, 3 mm ≤ X ≤ 7 mm, which is beneficial to ensure the wall strength of the spiral flow channel 300 while increasing the resistance of the bubble water in the spiral flow channel 300, increasing the residence time of the bubble water in the spiral flow channel 300, and increasing the dissolution ability of carbon dioxide gas.

[0057] This solution limits the length L of the steady flow column 230 between 20 mm and 40 mm and limits the spiral pitch X range of the spiral flow channel 300 between 3 mm and 7 mm, which is beneficial to increase the residence time of the bubble water in the spiral flow channel 300, increase the dissolution ability of carbon dioxide and the rectification effect, and is beneficial to ensure the wall strength of the spiral flow channel 300.

[0058] Furthermore, the flow guiding cap 220 is arranged in a conical or pyramidal shape. That is, in one embodiment, the flow guiding cap 220 is arranged in a conical shape; in the second embodiment, the flow guiding cap 220 is arranged in a pyramidal shape; the conical or pyramidal flow guiding cap 220 can gently guide the direction of the bubble water through a gradually shrinking flow channel, reducing local turbulence and pressure pulsation. Of course, this solution is not limited to this. In other embodiments, the flow guiding cap 220 can also be arranged in a hemispherical shape.

[0059] Optionally, the included angle α between the outer peripheral surface of the flow guiding cap 220 and the extension line of the outer peripheral surface of the steady flow member 200 ranges from 30° to 60°; this can further reduce the local pressure loss at the end face of the flow guiding cap 220.

[0060] In this embodiment, the flow stabilizer 200 includes a flow guiding cap 220 and a flow stabilizing column 230 which are connected to each other. The spiral flow channel 300 includes a first spiral section and a second spiral section which are connected and communicated with each other. The first spiral section is arranged on the flow guiding cap 220, and the second spiral section is arranged on the flow stabilizing column 230. Of course, this solution is not limited thereto. In other embodiments, the spiral flow channel 300 may also be only arranged on the flow stabilizing column 230.

[0061] Optionally, in this embodiment, the installation cavity 110 has a flow guiding section 111 arranged corresponding to the flow guiding cap 220. The flow guiding section 111 is arranged to be gradually expanded in the direction close to the water outlet 130, which is beneficial to better guiding the flow of the bubble water and further reducing the local pressure loss at the end face of the flow guiding cap 220.

[0062] Refer to Figure 4 、 Figure 6 and Figure 7 In this embodiment, a limiting column 240 is arranged at one end of the flow stabilizer 200 close to the water outlet 130, so as to form an expansion cavity 400 between the limiting column 240 and the flow stabilizing shell 100. The expansion cavity 400 is respectively communicated with the water outlet 130 and the spiral flow channel 300. It can be understood that the flow velocity of the bubble water is increased in the spiral flow channel 300. When the high-speed flowing bubble water reaches the expansion cavity 400, the flow velocity decreases, so as to avoid too fast flow velocity entering the water outlet 130, thereby improving the flow stabilizing effect of the flow stabilizer 10.

[0063] It should be noted that, refer to Figure 7 In one embodiment, the flow stabilizer 200 includes a flow guiding cap 220, a flow stabilizing column 230 and a limiting column 240 which are connected in sequence. The outer peripheral surface of the flow stabilizing column 230 is hermetically attached to the cavity wall of the installation cavity 110, and the flow guiding cap 220 is arranged close to the water inlet 120. Refer to Figures 1 to 3 In the second embodiment, the flow stabilizer 200 includes a flow guiding cap 220 and a flow stabilizing column 230 which are connected to each other. The outer peripheral surface of the flow stabilizing column 230 is hermetically attached to the cavity wall of the installation cavity 110, and the flow guiding cap 220 is arranged close to the water inlet 120. Refer to Figures 4 to 6 In the third embodiment, the flow stabilizer 200 includes a flow stabilizing column 230 and a limiting column 240 which are connected to each other. The outer peripheral surface of the flow stabilizing column 230 is hermetically attached to the cavity wall of the installation cavity 110. In the fourth embodiment, the flow stabilizer 200 may also only include the flow stabilizing column 230, and the outer peripheral surface of the flow stabilizing column 230 is hermetically attached to the cavity wall of the installation cavity 110.

[0064] Optionally, the radial cross-section of the spiral flow channel 300 is triangular, circular, square or rhombic; specifically, in one embodiment, the radial cross-section of the spiral flow channel 300 is triangular, in the second embodiment, the radial cross-section of the spiral flow channel 300 is circular, in the third embodiment, the radial cross-section of the spiral flow channel 300 is square; in the fourth embodiment, the radial cross-section of the spiral flow channel 300 is rhombic.

[0065] Refer to Figure 1 、 Figure 3 、 Figure 4 and Figure 7 , optionally, the flow stabilizer 10 is provided with a flow stabilizer cover 140 detachably connected to the flow stabilizer housing 100 to cover the installation cavity 110, which can facilitate the installation or disassembly of the flow stabilizer 10 and is also convenient for later maintenance and cleaning. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer housing 100 may also include a first housing part and a second housing part that are mutually covered, and the installation cavity 110 is formed on the first housing part and the second housing part.

[0066] Furthermore, the flow stabilizer cover 140 and the flow stabilizer housing 100 are threadedly connected. It can be understood that the installation and disassembly of the threaded connection are convenient, which can improve the installation and disassembly efficiency of the flow stabilizer 10; moreover, the threaded connection has good sealing performance, which can improve the sealing effect of the connection position between the flow stabilizer cover 140 and the flow stabilizer housing 100. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer cover 140 may also be in interference sealing fit with the flow stabilizer housing 100.

[0067] Among them, in this embodiment, the flow stabilizer cover 140 is provided with internal threads, and the flow stabilizer housing 100 is provided with external threads adapted to the internal threads of the flow stabilizer cover 140. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer housing 100 is provided with internal threads, and the flow stabilizer cover 140 is provided with external threads adapted to the internal threads of the flow stabilizer housing 100.

[0068] Furthermore, the water inlet 120 is formed on the flow stabilizer cover 140.

[0069] Optionally, the flow stabilizer housing 100 includes a first section 150 and a second section 160 that are arranged at an angle and communicate with each other. The installation cavity 110 is formed in the first section 150. The flow stabilizer cover 140 covers one end of the first section 150 away from the second section 160, and the water outlet 130 is formed at one end of the second section 160 away from the first section 150, which can shorten the length of the flow stabilizer housing 100 in the axial direction. Of course, this solution is not limited to this. In other embodiments, the flow stabilizer housing 100 may also be integrally columnar.

[0070] Refer to Figure 1 、 Figure 4 、Figure 7 and Figure 8 Optionally, the flow stabilizer 10 further includes a bubbler 500 detachably connected to the flow stabilizing housing 100. The water outlet 130 is formed at one end of the water outlet channel of the bubbler 500 away from the flow stabilizing member 200. It can be understood that the bubbler 500 can adjust the size and distribution of bubbles, making the bubbles finer and more uniform, thus improving the taste or usage effect. Moreover, the bubbler 500 can further disperse the bubble water into multiple fluid streams, shaping and stabilizing the fluid, thereby reducing the splashing of the bubble water.

[0071] Further, in this embodiment, the flow stabilizing housing 100 includes a first section 150 and a second section 160 that are arranged at an angle and communicate with each other. The bubbler 500 is detachably connected to the second section 160.

[0072] Among them, in this embodiment, the end of the second section 160 is threadedly connected to the bubbler 500. This can improve the efficiency of installation and disassembly of the bubbler 500, and the airtightness of the threaded connection is relatively good. The tightness of the threaded connection can be used to improve the sealing performance between the bubbler 500 and the flow stabilizing housing 100. That is to say, the threaded connection can seal both when connecting the bubbler 500 and the flow stabilizing housing 100. In other words, one process can complete both sealing and installation, which can effectively improve the production efficiency of the flow stabilizer 10. Of course, this solution is not limited to this. In other embodiments, the end of the second section 160 can also be in interference fit with the bubbler 500, and a sealing gasket can be provided at the interference position.

[0073] Further, an external thread is provided at the end of the second section 160, and an internal thread adapted to the external thread of the second section 160 is provided on the housing of the bubbler 500. Of course, this solution is not limited to this. In other embodiments, an internal thread can also be provided at the end of the second section 160, and an external thread adapted to the internal thread of the second section 160 is provided on the housing of the bubbler 500.

[0074] Optionally, the water outlet flow channel is provided with a first bubble net 510 and a second bubble net 520 at intervals in the direction close to the water outlet 130. The pore diameter of the first bubble net 510 is smaller than that of the second bubble net 520. It can be understood that the first bubble net 510 further disperses the bubble water into multiple fluid streams, shaping and stabilizing the flow of the bubble water. Then the bubble water flows to the second bubble net 520. It can be understood that the air pressure of the second bubble net 520 is basically equal to the atmospheric pressure. A large amount of undissolved carbon dioxide (including the carbon dioxide gas precipitated by the reverse reaction of carbonic acid due to the pressure drop) is wrapped by the surface tension of the water, forming a liquid film-wrapped air state, so that the bubble water flows out of the water outlet 130 stably. Moreover, the pore diameter of the first bubble net 510 is smaller than that of the second bubble net 520, which is beneficial to the staged treatment of bubble water. First, the water flow is refined through the small-pore-diameter net, and then the air is further mixed through the large-pore-diameter net, thereby optimizing the uniformity and stability of the bubbles. Of course, this solution is not limited to this. In other embodiments, there may be only one bubble net in the water outlet flow channel of the bubbler 500.

[0075] Further, the pore diameter range of the first bubble net 510 is 0.1 mm to 0.3 mm, and the pore diameter range of the second bubble net 520 is 0.8 mm to 1.1 mm. This can ensure the pore diameter difference between the first bubble net 510 and the second bubble net 520, so that the water flow velocity of the bubble water is matched, and the mixing effect is improved.
