Description

Technical Field

[0001] The present invention relates to the technical field of micro-nano bubbles, in particular to an air dissolving tank, an air dissolving component and a water heater having the same. Background Art

[0002] Micro-nano bubble water refers to water containing a large number of tiny bubbles with diameters ranging from 0.1 to 50 μm. Micro-nano bubble water is currently widely used in industrial water treatment and water pollution treatment, and is now also being used in daily life and beauty products.

[0003] Due to their small size, micro-nano bubbles exhibit distinct properties from ordinary bubbles, such as long lifespan, high interfacial zeta potential, and high mass transfer efficiency. These properties can be exploited to create micro-nano bubble water for degrading agricultural residues in fruits and vegetables, killing bacteria and some viruses, and even partially removing antibiotics and hormones found in some meats.

[0004] Currently, micro-nano bubble water generation technologies can be categorized by their bubble generation mechanisms: pressurized dissolved air, air induction, and electrolytic precipitation. Traditional pressurized dissolved air methods produce tiny bubbles, but require a booster pump for pressure increase. This results in a large system with high noise and vibration, making it unsuitable for use in small equipment. Furthermore, the system is costly, has a low cost-performance ratio, is complex to operate and control, and offers a poor user experience. Summary of the Invention

[0061] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0062] Reference below Figures 1-9 The dissolved air tank 100 according to the first embodiment of the present invention includes: a shell 1 and a partition 2.

[0063] Specifically, an air inlet 14, a water inlet 15 and a water outlet 16 are formed on the shell 1, and a partition 2 is arranged in the shell 1, and the partition 2 divides the internal space of the shell 1 into a mixing chamber 9 and a dissolving water chamber 10. The mixing chamber 9 is connected to the dissolving water chamber 10 to facilitate the mixing of air bubbles in the mixing chamber 9 and the water in the dissolving water chamber 10.

[0064] The air inlet 14 is in communication with both the mixing chamber 9 and the dissolving water chamber 10, and is used to inject high-pressure air into the mixing chamber 9 and the dissolving water chamber 10. That is, the air inlet 14 is in communication with the mixing chamber 9, which is in communication with the dissolving water chamber 10. Therefore, the air inlet 14 is in communication with both the mixing chamber 9 and the dissolving water chamber 10. Furthermore, the water inlet 15 is in communication with the mixing chamber 9, and is used to inject high-pressure water into the mixing chamber 9. The water outlet 16 is in communication with the dissolving water chamber 10.

[0065] When using the air dissolving tank 100, first close the water inlet 15, and high-pressure air enters the housing 1 of the air dissolving tank 100 through the air inlet 14, discharging the water in the air dissolving tank 100 from the water outlet 16, and air enters the air dissolving tank 100. Then, after the air dissolving tank 100 is partially or completely filled with air, the compressed air supply is stopped. Then, open the water inlet 15, and high-pressure water enters the mixing chamber 9 of the air dissolving tank 100 through the water inlet 15. At this time, the pressure in the mixing chamber 9 is consistent with the water inlet pressure. In the high-pressure mixing chamber 9, the water flow impacts to form air bubbles and a mixed flow, which increases the contact area between air and water and increases the content of air dissolved in water, ultimately forming dissolved water. The dissolved water flows into the dissolved water chamber 10 through the partition 2.

[0066] According to the gas dissolving tank 100 of the embodiment of the present invention, the internal space of the shell 1 is divided into a mixing chamber 9 and a dissolved water chamber 10 by a partition 2. The mixing chamber 9 is connected to the dissolved water chamber 10. During the gas dissolving process, high-pressure air is first injected into the shell 1, and then high-pressure water is injected into the mixing chamber 9. In this way, the water flow impact forms an air bubble mixed flow, and finally forms dissolved water. Therefore, the structure is simple and the gas dissolving efficiency is high.

[0067] Furthermore, the gas dissolving tank 100 can be designed in different sizes according to user needs, meeting different usage scenarios. Furthermore, the gas dissolving tank 100 of the present invention can be modularized as a whole, with a small size and light weight. It can be assembled as a whole in a gas water heater or an electric water heater to produce micro-nano bubble water, which can be used in the kitchen for washing vegetables, etc., thus solving the problems of the existing gas dissolving tank 100, such as complex structure, high cost, low gas dissolving efficiency, and large size.

[0068] In some embodiments of the present invention, the mixing chamber 9 and the dissolving water chamber 10 are spaced apart on the left and right, the water inlet 15 and the air inlet 14 are both formed on the top of the shell 1, and the water inlet 15 is formed directly above the mixing chamber 9, which is beneficial to improving the quality of the air bubble mixing flow. After the water flows into the water inlet 15, the direction of the water flow is parallel to the partition 2, and the water flow parallel to the partition 2 increases the pressure of the water flow.

[0069] That is to say, the dissolving water chamber 10 and the mixing chamber 9 are spaced apart on the left and right, and a water inlet 15 and an air inlet 14 are formed on the top of the shell 1. The air inlet 14 is formed at the top of the shell 1, and the water inlet 15 is also formed at the top of the shell 1, and the water inlet 15 is formed directly above the mixing chamber 9. The water flow entering the mixing chamber 9 through the water inlet 15 is parallel to the partition 2, which further improves the quality of the air bubble mixed flow and increases the content of air bubbles. The water outlet 16 is formed at the bottom of the shell 1. The water inlet 15, the air inlet 14 and the water outlet 16 are cleverly positioned and have a reasonable structure.

[0070] Reference Figure 1As shown, the mixing chamber 9 is located on the left side of the partition 2, the dissolving water chamber 10 is located on the right side of the partition 2, the water inlet 15 is formed directly above the mixing chamber 9, and the high-pressure water flow entering the mixing chamber 9 from the water inlet 15 is parallel to the partition 2, the water outlet 16 is formed at the bottom of the shell 1, and the water outlet 16 is formed below the dissolving water chamber 10, the air inlet 14 is formed at the top of the shell, and the main cavity 13 is formed with an avoidance recess facing the inside of the main cavity 13 at the water outlet 16, the air inlet 14 and the water inlet 15. The avoidance recess improves the stability of the overall structure of the shell 1, ensures the safety of the shell 1, saves assembly space, and reduces the volume of the dissolving tank 100.

[0071] In some embodiments of the present invention, the ratio of the width of the mixing chamber 9 in the left-right direction to the width of the dissolving water chamber 10 in the left-right direction is in the range of 1 / 5 to 1. That is, in the left-right direction, the ratio of the width of the mixing chamber 9 to the width of the dissolving water chamber 10 is in the range of one-fifth to one. When the ratio of the width of the mixing chamber 9 to the width of the dissolving water chamber 10 is less than one-fifth, the width of the mixing chamber 9 in the left-right direction is small, and sufficient air bubble mixing flow cannot be generated in the mixing chamber 9, thereby affecting the bubble content and quality of the dissolved water. When the ratio of the width of the mixing chamber 9 to the width of the dissolving water chamber 10 is greater than 1, the width of the mixing chamber 9 in the left-right direction is large, and the width of the dissolving water chamber 10 in the left-right direction is small. There is more air bubble mixing flow in the mixing chamber 9, and less water to be dissolved in the dissolving water chamber 10. The air bubble mixing flow cannot be completely dissolved in the water, resulting in a waste of resources and affecting the user's need for dissolved water.

[0072] like Figure 1 As shown, in the left-right direction, the ratio between the width of the mixing chamber 9 and the width of the dissolved water chamber 10 is within the range of one-fifth to one, preventing the water flow parallel to the partition 2 from impacting the partition 2 and affecting the generation of the air bubble mixed flow. When the water flow impacts and forms an air bubble mixed flow, the air bubbles in the air bubble mixed flow can be made denser and the micro-nano bubble content is higher in the relatively small mixing chamber 9, thereby improving the quality of the micro-nano bubble water. In this way, the generated air bubble mixed flow is sufficient to dissolve into the dissolved water, without causing waste of resources, and ensuring the quality of the dissolved water.

[0073] For example, in the left-right direction, the ratio between the width of the mixing chamber 9 and the width of the dissolved water chamber 10 may be 1 / 5, 1 / 4, 1 / 3, 1 / 2, 1, and so on.

[0074] Preferably, if Figure 1As shown, in the left-right direction, the ratio between the width of the mixing chamber 9 and the width of the dissolving water chamber 10 is 1 / 2. In this way, the micro-nano bubble content in the air bubble mixed flow is guaranteed to be sufficient, thereby improving the economical practicality of the air dissolving tank 100.

[0075] In some embodiments of the present invention, the ratio between the volume of the mixing chamber 9 and the volume of the dissolving water chamber 10 is in the range of 1 / 4 to 1. When the ratio between the volume of the mixing chamber 9 and the volume of the dissolving water chamber 10 is less than one-quarter, the volume of the mixing chamber 9 is small, the air bubble mixed flow generated in the mixing chamber 9 is insufficient, and the content of bubbles in the dissolved water cannot be guaranteed, thereby reducing the quality of the dissolved water and affecting the user experience; when the ratio between the volume of the mixing chamber 9 and the volume of the dissolving water chamber 10 is greater than one, the volume of the mixing chamber 9 is large, the air bubble mixed flow in the mixing chamber 9 is large, and the water to be dissolved in the dissolving water chamber 10 cannot meet the requirement of dissolving as much air bubble mixed flow as possible, and there is a large amount of remaining air bubble mixed flow, resulting in a waste of resources.

[0076] For example, the ratio between the volume of the mixing chamber 9 and the volume of the dissolved water chamber 10 may be 1 / 4, 1 / 3, 1 / 2, 1, and so on.

[0077] Preferably, if Figure 1 As shown, the ratio between the volume of the mixing chamber 9 and the volume of the dissolving water chamber 10 is 1 / 2. This ensures that the volume capacity of the dissolving water chamber 10 is sufficient for the user and that the micro-nano bubble content in the air bubble mixed flow is sufficient, thereby improving the economic practicality of the air dissolving tank 100.

[0078] In some embodiments of the present invention, the ratio of the vertical height of the partition 2 to the inner diameter of the shell 1 at the position corresponding to the partition 2 is between 0.4 and 0.9. In other words, the ratio of the vertical height of the partition 2 to the inner diameter of the shell 1 at the position corresponding to the partition 2 is within the range of 0.4 to 0.9. When the ratio of the vertical height of the partition 2 to the inner diameter of the shell 1 at the position corresponding to the partition 2 is less than 0.4, the air bubble mixed flow can only enter the dissolving water chamber 10 through the through hole 21 of the partition 2, resulting in less air bubble mixed flow and incomplete and uneven mixing of the air bubble mixed flow with water, thereby reducing the content of micro-nano bubbles in the micro-nano bubble water and thus reducing the quality of the micro-nano bubble water.

[0079] When the ratio of the height of the partition 2 in the vertical direction to the inner diameter of the shell 1 at the position corresponding to the partition 2 is greater than 0.9, the distance between the upper end of the partition 2 and the upper end of the shell 1 is large, and a large amount of air bubble mixed flow directly enters the dissolving water chamber 10 from the upper end of the partition 2 through the mixing chamber 9, resulting in incomplete and uneven mixing of the air bubble mixed flow and water in the main cavity 13, reducing the number of micro-nano bubbles in the micro-nano bubble water, thereby reducing the quality of the micro-nano bubble water.

[0080] Therefore, the ratio between the height of the partition 2 in the vertical direction and the inner diameter of the shell 1 at the position corresponding to the partition 2 is between 0.4 and 0.9, which accelerates the mixing speed of the air bubble mixed flow and water in the main cavity 13 while ensuring the sufficient mixing of the air bubble mixed flow and water.

[0081] For example, the ratio between the height of the partition 2 in the up and down directions and the inner diameter of the shell 1 corresponding to the partition 2 can be: 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, etc.

[0082] Preferably, if Figure 1 As shown, the ratio between the height of the partition 2 in the vertical direction and the inner diameter of the shell 1 at the position corresponding to the partition 2 is 0.4. In this way, the quality of the micro-nano bubble water is guaranteed, and the mixing speed of the air bubble mixed flow and water in the main cavity 13 is accelerated, and the air bubble mixed flow and water are fully mixed.

[0083] In some embodiments of the present invention, the housing 1 is cylindrical. That is, in the left-right direction, the housing 1 is formed into a cylindrical shape surrounding a horizontal axis. This cylindrical shape facilitates the generation of air bubbles, increases the micro-nano bubble content of the micro-nano bubble water, and enhances the user experience. Furthermore, the structure is simple, manufacturing is convenient, and production costs are reduced.

[0084] In one embodiment of the present invention, Figure 7 As shown, a plurality of through holes 21 penetrating the partition plate 2 along the thickness direction are formed on the partition plate 2. The plurality of through holes 21 are conducive to the full mixing of the air bubble mixed flow and the water.

[0085] Furthermore, the diameter of the through hole 21 is within the range of 2 mm to 8 mm, so as to neither affect the full contact between the air bubble mixed flow and water nor hinder the mixing of the air bubble mixed flow and water.

[0086] For example, the diameter of the through hole 21 can be 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, etc.

[0087] In some embodiments of the present invention, the axis of the housing 1 extends horizontally (eg Figure 1 The partition 2 is arranged perpendicular to the axis of the housing 1, as shown in the left and right directions. Figure 1 As shown, the axis of the shell 1 extends in the left-right direction, and the partition 2 is arranged in the vertical direction perpendicular to the axis of the shell 1. The structure is simple and easy to manufacture, thereby reducing production costs and shortening production and installation time.

[0088] Furthermore, the lower end of the partition 2 (eg Figure 1 The lower end of the partition 2 shown in FIG. 1 is connected to the inner peripheral wall of the shell 1, and the upper end of the partition 2 (for example Figure 1 The upper end of the partition 2 is spaced apart from the inner peripheral wall of the housing 1. In other words, the height of the partition 2 is less than the inner diameter of the housing 1. In this way, part of the air bubble mixed flow can enter the dissolving water chamber 10 from the upper end of the partition 2 through the mixing chamber 9, thereby accelerating the mixing speed of the air bubble mixed flow and water in the main chamber 13.

[0089] In some embodiments of the present invention, Figure 7 As shown, the lower edge of the partition 2 is formed with an upwardly concave water channel 23. The water channel 23 is used to allow the passage of air bubble mixed flow and water. The water channel 23 penetrates the partition 2 along the thickness direction of the partition 2. A plurality of through holes 21 are arranged on the partition 2 in an interval along the vertical direction, and the plurality of through holes 21 are aligned with the water channel 23 in the vertical direction. In this way, the air bubble mixed flow in the mixing chamber 9 can not only enter the dissolution water chamber 10 through the plurality of through holes, but also enter the dissolution water chamber 10 through the water channel, thereby accelerating the mixing speed of the air bubble mixed flow and water. Furthermore, the peripheral edge of the partition 2 is formed with a connecting flange 22 extending along the axis of the shell 1. The partition 2 is welded to the inner peripheral wall of the shell 1 via the connecting flange 22. The connecting flange 22 increases the welding area between the partition 2 and the inner peripheral wall of the shell 1, thereby enhancing the strength of the welded connection between the partition 2 and the shell 1.

[0090] Furthermore, the connecting flange 22 includes a plurality of flange portions spaced apart in the circumferential direction of the partition 2, and in the direction from the fixed end of the connecting flange 22 toward the free end (for example Figure 8In the direction from right to left shown in the figure, the spacing between two adjacent flanged portions gradually increases. In other words, the spacing between two adjacent flanged portions at the fixed end is smaller, and the spacing between two adjacent flanged portions at the free end is larger. The spacing between two adjacent flanged portions at the fixed end is smaller than the spacing between two adjacent flanged portions at the fixed end. This facilitates operation when welding the partition 2. Since the pressure of the liquid and gas in the dissolved gas tank 100 is relatively high during use, the multiple flanged portions increase the area of ​​the welded connection between the partition 2 and the shell 1, thereby making the connection between the partition 2 and the shell 1 more stable, improving the safety of the dissolved gas tank 100 during use, and ensuring the service life of the dissolved gas tank 100.

[0091] In some embodiments of the present invention, the housing 1 may include: a main cavity 13, a first end cover 11 and a second end cover 12, the main cavity 13 having two ends (eg Figure 1 The left and right ends of the main cavity shown in FIG are both open in a cylindrical shape, and the first end cover 11 is sealed at one end of the main cavity 13 (for example Figure 2 The second end cover 12 is sealed at the other end of the main cavity 13 (eg Figure 2 In this way, the first end cover 11 and the second end cover 12 are respectively sealed at both ends of the main cavity 13, thereby simplifying the overall structure of the shell 1, facilitating separate molding of the various parts of the shell, and facilitating manufacturing.

[0092] Reference Figure 2 As shown, the main cavity 13 is cylindrical and extends in the left-right direction, and both left and right ends of the main cavity 3 are open. The first end cover 11 is sealed at the left end of the main cavity 13, and the second end cover 12 is sealed at the right end of the main cavity 13. A downwardly recessed first mounting portion 133 is formed on the top of the main cavity 13, and the upper surface of the first mounting portion 133 is formed as a plane. The air inlet 14 and the water inlet 15 both pass through the first mounting portion 133 in the thickness direction.

[0094] In this way, the first mounting portion 133 and the second mounting portion 134 are both formed with an avoidance recess toward the interior of the main cavity 13, thereby facilitating the installation of components such as the water inlet valve 4, the water inlet connector 3, the air inlet connector 5, the one-way valve 6, and the water outlet connector 7 described below, thereby saving assembly space and reducing the volume of the air dissolving tank 100.

[0095] In some embodiments of the present invention, the main cavity 13 is formed into a circular cylindrical shape, such as Figure 4As shown, the first end cover 11 is in the shape of a plate. The first end cover 11 is recessed from one side toward the other side along the thickness direction to form a first groove 112. The first groove 112 is annular and extends around the central axis of the first end cover 11. In other words, the first end cover 11 is recessed along the thickness direction to form the first groove 112. The first groove 112 is annular and extends around the central axis of the first end cover 11. The structure of the first end cover 11 is simple and easy to manufacture. The recessed structure of the first groove 112 not only improves the structural strength of the first end cover 11 and the stability of the housing 1, but also facilitates the assembly of the first end cover 11 with the main cavity 13.

[0096] Further, if Figure 5 As shown, the second end cover 12 is in the shape of a plate. The second end cover 12 is recessed from one side toward the other side along the thickness direction to form a second groove 122. The second groove 122 is annular and extends around the central axis of the second end cover 12. In other words, the second end cover 12 is recessed from the right side toward the left side along the thickness direction to form the second groove 122. The second groove 122 is annular and extends around the central axis of the second end cover 12. The structure of the second end cover 12 is simple and easy to produce. The recessed structure of the second groove 122 not only improves the structural strength of the second end cover 12 and the stability of the housing 1, but also facilitates the assembly of the second end cover 12 with the main cavity 13.

[0097] In one embodiment of the present invention, the first groove 112 and the second groove 122 are both recessed toward the inner side of the main cavity 13 along the axis direction of the main cavity 13.

Thus, both the first groove 112 and the second groove 122 are recessed toward the inner side of the main cavity 13, thereby improving the structural installation stability of the housing 1. The first groove 112 and the second groove 122 enhance the safety factor of the air dissolving tank 100. Furthermore, the first groove 112 and the second groove 122 have a simple structure, making them easy to assemble. Furthermore, the inwardly recessed first groove 112 and the second groove 122 can also save space and reduce the volume of the air dissolving tank 100.

[0098] In some embodiments of the present invention, a first flange 111 is formed on the periphery of the first end cover 11 and extends in an annular shape along the periphery of the first end cover 11. The first flange 111 extends outward away from the main cavity 13 along the axis of the main cavity 13. Figure 2As shown, the first flange 111 is annular and extends along the circumference of the first end cover 11. The first flange 111 of the first end cover 11 extends to the left in a direction away from the main cavity 13. The first end cover 11 has a simple structure and is easy to manufacture. It is convenient to use the first flange 111 to achieve a lap connection with the main cavity 13, thereby improving the connection reliability and sealing performance between the first end cover 11 and the main cavity 13.

[0099] The second end cover 12 is formed with a second flange 121 extending in a ring shape along the periphery of the second end cover 12. The second flange 121 extends outward away from the main cavity 13 along the axis of the main cavity 13. Figure 4 As shown, the second flange 121 is annular and extends along the circumference of the second end cover 12. The second flange 121 of the second end cover 12 extends to the right in a direction away from the main cavity 13. The second end cover 12 has a simple structure and is easy to manufacture. It is easy to install with the main cavity 13 and to use the second flange 121 to achieve a lap connection with the main cavity 13, thereby improving the connection reliability and sealing performance between the second end cover 11 and the main cavity 13.

[0100] Furthermore, a third flange 131 is formed at one axial end of the main cavity 13, and a fourth flange 132 is formed at the other axial end of the main cavity 13. Both the third flange 131 and the fourth flange 132 extend outward along the axis of the main cavity 13. The third flange 131 is located radially outward of the first flange 111 and is sealed to the first flange 111. The fourth flange 132 is located radially outward of the second flange 121 and is sealed to the second flange 121. Thus, the main cavity 13 can utilize the third flange 131 and the fourth flange 132 to achieve an overlapping connection with the first end cover 11 and the second end cover 12, thereby ensuring the sealing performance of the housing 1.

[0101] Reference Figure 2 As shown, a third flange 131 is formed at the left end of the main cavity 13, and a fourth flange 132 is formed at the right end of the main cavity 13. In this way, the third flange 131 is sealed with the first flange 111 of the first end cover 11, and the fourth flange 132 is sealed with the second flange 121 of the second end cover 12, thereby enhancing the sealing effect of the shell 1 and avoiding leakage of gas and liquid in the shell 1, thereby ensuring the sealing of the dissolved gas tank 100.

[0102] Reference Figure 3 and Figure 4As shown, the middle portion of the first end cover 11 bulges in a direction away from the main cavity 13, and the periphery of the first end cover 11 forms a first flange 111 in a direction away from the main cavity 13, and the left end of the main cavity 13 is formed into a third flange 131 adapted to the first flange 111 of the first end cover 11, thereby improving the sealing effect between the first end cover 11 and the main cavity 13; the middle portion of the second end cover 12 bulges in a direction away from the main cavity 13, and the periphery of the second end cover 12 forms a second flange 121 in a direction away from the main cavity 13, and the right end of the main cavity 13 is formed into a fourth flange 132 adapted to the second flange 121 of the second end cover 12, thereby improving the sealing effect between the second end cover 12 and the main cavity 13, the first end cover 11 and the second end cover 12 have a simple structure, low production cost, and good sealing effect of the shell 1.

[0103] Among them, preferably, the first flange 111 of the first end cover 11 and the third flange 131 of the main cavity 13 are connected by welding, and the second flange 121 of the second end cover 12 and the fourth flange 132 of the main cavity 13 are connected by welding. The welding connection has a high connection strength, which enhances the sealing of the shell 1 and extends the service life of the shell 1.

[0104] For example, the first end cover 11 and the main cavity 13 as well as the second end cover 12 and the main cavity 13 can be welded by argon arc welding or integral brazing.

[0105] Optionally, the main cavity 13 is a steel pipe, and the first end cap 11 and the second end cap 12 are welded to the main cavity 13. The welded connection has good stability, thereby ensuring the assembly stability of the housing 1 and enhancing the sealing performance between the first end cap 11 and the second end cap 12 and the main cavity 13. In addition, by using standard steel pipe to cut the main cavity 13 to the required specifications and dimensions, production costs can be reduced.

[0106] In addition, in some embodiments of the present invention, a liquid level sensor may be provided in the mixing chamber 9, which can be used to detect the water level within the housing 1 in real time. Furthermore, the liquid level sensor may be communicatively connected to the water inlet valve 4 and the one-way valve 6 described below. For example, the air dissolving tank 100 may further include a controller, which is communicatively connected to the liquid level sensor, the water inlet valve 4, the one-way valve 6, and the like. Thus, when the liquid level sensor detects that the main chamber 13 is filled with water, the liquid level sensor provides a feedback signal to the controller, which then controls the opening and closing of the water inlet 15, the air inlet 14, and the water outlet 16, thereby controlling the air dissolving tank 100 to drain water and intake air.

[0107] The following will refer to Figures 1-9 A dissolved air tank 100 according to a specific embodiment of the first aspect of the present invention is described.

[0108] Reference Figure 1 and Figure 2 As shown, the dissolved gas tank 100 includes: a shell 1 and a partition 2, the shell 1 includes: a first end cover 11, a second end cover 12 and a main cavity 13, the partition 2 is located inside the main cavity 13, and a through hole 21, a connecting flange 22 and a water trough 23 are formed on the partition 2. The connecting flange 22 is welded to the inner peripheral wall of the main cavity 13, and the partition 2 separates the main cavity 13 into a mixing chamber 9 and a dissolved water chamber 10. The mixing chamber 9 is located on the left side of the partition 2. The dissolved water The cavity 10 is located on the right side of the partition 2, the water inlet 15 is formed just above the mixing cavity 9, the water outlet 16 is formed at the bottom of the shell 1, and the water outlet 16 is formed below the dissolved water cavity 10, the air inlet 14 is formed at the top of the shell, and the main cavity 13 is formed with an avoidance recess facing the interior of the main cavity 13 at the water outlet 16, the air inlet 14 and the water inlet 15. The overall structure of the dissolved air tank 100 is simple, easy to install and maintain, and has low production cost.

[0109] Reference below Figures 1-10 The air dissolving component 1000 according to the second embodiment of the present invention is described. The air dissolving component 1000 includes: a water inlet connector 3, an air inlet connector, and a water outlet connector.

[0110] like Figure 1 As shown, the water outlet connector 7 is connected to the water outlet 16, and the water inlet connector 3 is in the vertical direction (for example Figure 3 The lower end of the water inlet connector 3 (e.g. Figure 3 The lower end of the water inlet connector 3 shown in the figure) is sealed with the periphery of the water inlet 15. When the high-pressure water flows in the air inlet connector 5, the high-pressure water will not overflow the water inlet connector 3. One end of the air inlet connector 5 (for example Figure 3 The lower end of the air inlet connector 5 shown in the figure is sealed and connected to the periphery of the air inlet 14. When high-pressure air flows in the air inlet connector 5, the high-pressure air will not overflow the air inlet connector 5. Thus, overflow of high-pressure water when flowing in the water inlet connector 4 is avoided, and overflow of high-pressure air when flowing in the air inlet connector 5 is avoided, thereby ensuring the safety of the dissolved air component 1000 when in use.

[0111] According to the second embodiment of the present invention, the air dissolving component 1000 is divided into a mixing chamber 9 and a dissolving water chamber 10 by a partition 2. The mixing chamber 9 is connected to the dissolving water chamber 10, which is conducive to the impact of water flow to form an air bubble mixed flow, and finally form dissolved water. The structure is simple and the air dissolving efficiency is high. Different volumes can be designed according to needs to meet different usage scenarios. The air dissolving tank 100 is modular as a whole, with a small size and light weight. The module can be assembled in a gas water heater or an electric water heater to produce micro-nano bubble water, which can be used for washing vegetables in the kitchen.

[0112] In some embodiments, the air dissolving component 1000 further includes: a water inlet valve 4 and a one-way valve 6. The water inlet valve 4 is sealed and connected to the other end of the water inlet connector 3, and the one-way valve 6 is sealed and connected to the other end of the air inlet connector 5. Figure 3 As shown, the water inlet valve 4 is sealed and connected to the lower end of the water inlet joint 3, and the one-way valve 6 is sealed and connected to the upper end of the air inlet joint 5. The water inlet valve 4 is sealed and connected to the water inlet joint 3, and the water inlet joint 3 is sealed and connected to the water inlet 15, ensuring that the high-pressure water flow will not overflow in the water inlet valve 3 and the water inlet joint 4, the air inlet joint 5 is sealed and connected to the one-way valve 6, and the air inlet joint 5 is sealed and connected to the air inlet 14. When high-pressure air flows in the air inlet joint 5 and the one-way valve 6, the high-pressure air will not overflow from the air inlet joint 5 and the one-way valve 6, thereby ensuring the overall airtightness of the dissolved air component 1000, thereby ensuring the safety of the user when using it.

[0113] Reference Figure 2 As shown, an annular sealing groove 31 extending around the axis is formed on the outer wall of the water inlet joint 3, and a sealing ring 32 is provided in the annular sealing groove 31. The sealing ring 32 seals between the water inlet joint 3 and the water inlet valve 4. The annular sealing groove 31 can seal the main cavity 13 to prevent the high-pressure water flow from overflowing the water pressure dissolving device 100.

[0114] In some embodiments, the air inlet connector 5 includes a first pipe section 51 and a second pipe section 52. The first pipe section 51 extends vertically upward (eg Figure 1 The lower end of the first pipe section 51 (eg Figure 1 The lower end of the first pipe section 51 is connected to the housing 1, and one end of the second pipe section 52 (for example Figure 1 The left end of the second pipe section 52 shown in FIG. 5 is connected to the upper end of the first pipe section 51 (eg Figure 1 The upper end of the first pipe section 51 is connected, and the other end of the second pipe section 52 (for example Figure 1 The right end of the second pipe section 52 shown in FIG. 5 is extended upward in a direction away from the first pipe section 51, and the one-way valve 6 is connected to the other end of the second pipe section 52 (for example Figure 1 The right end of the second pipe section 52 is shown as being connected.

[0115] For example Figure 6 As shown, the first pipe section 51 extends vertically upward, the lower end of the first pipe section 51 is connected to the shell 1, the left end of the second pipe section 52 is connected to the upper end of the first pipe section 51, and the right end of the second pipe section 52 extends upwardly and obliquely in a direction away from the first pipe section 51. The one-way valve 6 is connected to the right end of the second pipe section 52. The curved air inlet connector 5 of this embodiment saves the installation space of the air dissolving tank 100. In addition, due to the presence of the bent section of the air inlet connector 5, the speed at which the high-pressure gas enters the shell 1 is slowed down, thereby ensuring the safety performance of the air dissolving tank 100.

[0116] In some embodiments of the present invention, the water inlet 15 and the air inlet 14 are both formed at the top of the shell 1, and the water inlet 15 is formed directly above the mixing chamber 9, which is beneficial to improving the quality of the air bubble mixed flow. The water outlet 16 is formed at the bottom of the shell 1, and the water inlet joint 3 is in the shape of a tube extending vertically upward. The water inlet valve 4 is connected to the upper end of the water inlet joint 3. The water inlet 15, the air inlet 14 and the water outlet 16 are cleverly positioned and have a reasonable structure.

[0117] Furthermore, a flow-increasing hole 41 for increasing the flow rate of water is provided at the outlet of the water inlet valve 4, and the central axis of the flow-increasing hole 41 is vertical (for example Figure 1 The flow-increasing hole 41 increases the water flow velocity. The central axis of the flow-increasing hole 41 is vertically arranged. Under the action of the water's own gravity, the water flows out faster, thereby further increasing the water flow velocity.

[0118] Reference Figure 6 As shown, a flow-increasing hole 41 is provided at the outlet of the water inlet valve 4. The flow-increasing hole 41 is used to increase the flow rate of the water. The central axis of the flow-increasing hole 41 is along the Figure 1 The vertical direction is shown, and the central axis is along Figure 1 As shown in the figure, the flow-increasing holes 41 are arranged in the upper and lower directions. Before the water flows out of the water inlet valve 4, the water flows through the flow-increasing holes 41, and the flow velocity of the water is increased. The water with increased flow velocity enters the mixing chamber 9 through the water inlet joint 3. The air bubbles in the mixed flow of air bubbles in the mixing chamber 9 are denser and the content of micro-nano bubbles is higher, thereby improving the quality of the micro-nano bubble water.

[0119] Optionally, the water inlet valve 4 may be a normally open valve or a normally closed valve.

[0120] In addition, in order to further improve the quality of micro-nano bubble water, it is necessary to continue to increase the water flow rate. A water pump can be set at the water inlet valve 4 to pressurize the water flow. The outflowing water is under the pressure of the water pump, and the influence of the water flow's own gravity further increases the water flow rate. The content of micro-nano bubbles in the micro-nano bubble water is higher, thereby improving the quality of the micro-nano bubble water.

[0121] In some embodiments of the present invention, the outlet end of the water outlet connector 7 is connected to a micro-nano bubble generator 8 for outputting the dissolved water within the housing 1 to the exterior of the air dissolving assembly 1000. The micro-nano bubble generator 8 is connected to the lower end of the water outlet connector 7. During use, the dissolved water is output to the exterior of the air dissolving assembly 1000 by utilizing its own gravity and the pressure within the housing 1. Under the action of the micro-nano bubble generator 8, bubble water is formed for the user. A connection end for threaded connection is formed on the outer peripheral wall of the lower end of the water outlet connector 7, facilitating the installation and use of components at the lower end of the water outlet connector 7. The threaded connection has a wide range of applications and is easy to use.

[0122] Specifically, if Figure 10 As shown, the micro-nano bubble generator 8 includes a cylinder 83 and an inner core 82. The cylinder 83 is located within the bubble water outlet, and the inner wall of the cylinder 83 forms a water flow cavity. The inner core 82 is located within the water flow cavity, and a gap water flow channel 81 is formed between the inner wall of the cylinder 83 and the outer wall of the inner core 82. The cross-sectional area of ​​the gap water flow channel 81 shows a trend of first decreasing and then increasing from top to bottom. In this way, when the water containing dissolved gas flows through the micro-nano bubble generator 8, the pressure at different locations is different. After the pressure of the dissolved water is released, the gas dissolved in the water is easily formed into tiny bubbles, thereby improving the bubble production effect and further facilitating the production of bubble water.

[0123] The following will refer to Figures 1-9 A dissolved air component 1000 according to a specific embodiment of the second aspect of the present invention is described.

[0124] Reference Figure 3 As shown, the air dissolving component 1000 includes: an air dissolving tank 100, a water inlet joint 3, a water inlet valve 4, an air inlet joint 5, a one-way valve 6, a water outlet joint 7, and a micro-nano bubble generator 8. The air dissolving tank 100 includes: a shell 1 and a partition 2, wherein the shell 1 includes: a first end cover 11, a second end cover 12 and a main cavity 13, the partition 2 is located inside the main cavity 13, and a through hole 21, a connecting flange 22 and a water trough 23 are formed on the partition 2. The connecting flange 22 is welded to the inner peripheral wall of the main cavity 13, and the partition 2 separates the main cavity 13 into a mixing chamber 9 and a dissolving water chamber 10. The mixing chamber 9 is located on the left side of the partition 2, and the dissolving water chamber 10 is located on the right side of the partition 2. The water inlet 15 is formed directly above the mixing chamber 9, the water outlet 16 is formed at the bottom of the shell 1, and the water outlet 16 is formed below the dissolving water chamber 10, and the air inlet 14 is formed at the bottom of the shell 1. At the top of the shell, the main cavity 13 is formed with avoidance recesses facing the inside of the main cavity 13 at the water outlet 16, the air inlet 14 and the water inlet 15. The lower end of the water inlet joint 3 is sealed with the periphery of the water inlet 15, the water inlet valve 4 is sealed with the upper end of the water inlet joint 3, the lower end of the air inlet joint 5 is sealed with the periphery of the air inlet 14, the one-way valve 6 is connected to the upper end of the air inlet joint 5, the water outlet joint 7 is connected to the position of the water outlet 16, and the water outlet joint 7 is connected to the micro-nano bubble generator 8. A connection end for threaded connection is formed on the outer peripheral wall of the lower end of the water outlet joint 7. The overall structural design of the dissolved air component 1000 is ingenious and easy to install and maintain.

[0125] When using the air dissolving assembly 1000 to dissolve air, close the water inlet valve 4, open the one-way valve 6, and high-pressure air enters the shell 1 of the air dissolving tank 100 through the air inlet 14, and the water in the air dissolving tank 100 is discharged from the water outlet 16, and the air enters the main cavity 13. Then, after the main cavity 13 is partially or completely filled with air, the supply of high-pressure air is stopped, and the water inlet 15 is opened. The high-pressure water enters the mixing cavity 9 of the air dissolving tank 100 through the water inlet 15. At this time, the pressure in the mixing cavity 9 is consistent with the water inlet pressure. The water flow increases its flow rate through the flow-increasing hole 41 and impacts the mixing chamber 9 to form an air bubble mixed flow, thereby increasing the contact area between air and water and increasing the content of air dissolved in water. The air bubble mixed flow flows into the dissolved water chamber 10 through the water groove and the through hole on the partition 2. The air bubble mixed flow is fully mixed with the water in the shell to eventually form dissolved water. The water outlet joint 7 is connected to the micro-nano bubble generator 8. The dissolved water flows out from the water outlet joint 7 and flows through the micro-nano bubble generator 8 connected to the water outlet joint 7, thereby generating micro-nano bubble water.

[0126] When the user assembles the micro-nano bubble generator 8 in the kitchen faucet, it can be used to wash vegetables, fruits, dishes, etc. in the kitchen.

[0127] When the user assembles the micro-nano bubble generator 8 in the bathroom faucet, it can be used for washing face, brushing teeth, skin care, etc.

[0128] When the user assembles the micro-nano bubble generator 8 in the shower head in the bathroom, it can be used for bathing and cleaning.
