Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] The following is for reference. Figures 1-3The bubble generating device 100 according to an embodiment of the present invention is described. By providing a bubble generating module 101 and a respirator module 102 in the bubble generating device 100, gas and liquid can be mixed in the bubble generating module 101 for the washing function of the device, and the internal gas of the device can be discharged in the respirator module 102 for breathing inside the device, maintaining the internal and external pressure balance. The bubble generating module 101 and the respirator module 102 are integrated into one unit, realizing the arrangement of the two in a limited space. The structure is more compact, the function is more complete, and the use effect is better, thereby improving the user experience.

[0038] like Figures 1-3 As shown, a bubble generating device 100 according to an embodiment of the present invention includes: a bubble generating module 101 and a respirator module 102.

[0039] A dissolved gas space 12 is formed inside the bubble generating module 101. The bubble generating module 101 is provided with an air inlet 13, a liquid inlet 14 and a liquid outlet 15 respectively connected to the dissolved gas space 12. The liquid entering through the liquid inlet 14 and the gas entering through the air inlet 13 are suitable to be mixed in the dissolved gas space 12 and flow out from the liquid outlet 15.

[0040] Specifically, a portion of the bubble generating module 101 can be configured as a dissolved gas space 12. The dissolved gas space 12 is used to mix liquid and gas. The bubble generating module 101 has a liquid inlet 14 and a liquid outlet 15. The liquid inlet 14 is used to introduce liquid, and the liquid outlet 15 is used to discharge liquid. The bubble generating module 101 also has an air inlet 13 for communicating with the external space to introduce gas. The liquid inlet 14, air inlet 13, and liquid outlet 15 are all connected to the dissolved gas space 12. Thus, gas from outside the bubble generating module 101 can enter the dissolved gas space 12 through the air inlet 13, and liquid can enter the dissolved gas space 12 through the liquid inlet 14. The gas and liquid mix within the dissolved gas space 12, and the resulting gas-liquid mixture flows out from the liquid outlet 15, achieving pre-mixing of gas and liquid. The air inlet 13 facilitates the introduction of external gas into the dissolved gas space 12, providing more gas for gas-liquid mixing and improving gas-liquid mixing efficiency.

[0041] Furthermore, the liquid encapsulating the bubbles formed by the pre-mixed gas-liquid mixture in the dissolved gas space 12 can be used to wash the items. The more bubbles formed after the gas and liquid dissolve in the dissolved gas space 12, the better the cleaning effect of the items.

[0042] Furthermore, the liquid outlet 15 is connected to the aerator 9, which is used to mix water and air to generate bubbles for effective cleaning of the items to be cleaned. By connecting the liquid outlet 15 to the aerator 9, the dissolved air space 12 can be connected to the aerator 9. In this way, the gas-liquid mixture pre-mixed in the dissolved air space 12 can be introduced into the aerator 9 through the liquid outlet 15. In the aerator 9, it is further separated into liquid containing microbubbles. The liquid containing microbubbles can be used for washing the items.

[0043] The respirator module 102 is connected to the bubble generating module 101. An exhaust space 5 is formed inside the respirator module 102. The exhaust space 5 is provided with an exhaust inlet 51 and an exhaust outlet 52. The exhaust inlet 51 and the exhaust outlet 52 are respectively connected to the external space.

[0044] Specifically, the respirator module 102 is connected to the bubble generating module 101, which integrates the respirator module 102 and the bubble generating module 101 into a single structure. This allows for the mixing of gas and liquid within the bubble generating module 101 for the equipment's washing function, and also allows for the emission of internal gases within the respirator module 102. This results in a more compact structure and more complete functions.

[0045] The exhaust space 5 of the respirator module 102 is used for venting gas. A portion of the respirator module 102 can be configured as the exhaust space 5. For example... Figure 1 As shown, the exhaust space 5 is provided with an exhaust inlet 51 for discharging gas, and the exhaust space 5 is also provided with an exhaust outlet 52 for communicating with the external space. In this way, the gas entering through the exhaust inlet 51 passes through the exhaust space 5 and is discharged from the respirator module 102 through the exhaust outlet 52.

[0046] Furthermore, after connecting the bubble generator 100 to some cleaning equipment, the bubble generator module 101 generates a large amount of gas-liquid mixture containing gas for cleaning items. During the cleaning process, heated gas is generated in the cleaning space. As the gas increases and the pressure increases, the gas in the cleaning equipment can enter the exhaust space 5 from the exhaust inlet 51 and be discharged from the exhaust outlet 52 of the exhaust space 5. This reduces the pressure during the cleaning process, improves the safety and stability of cleaning items, and has a reasonable and reliable structure.

[0047] According to an embodiment of the present invention, the bubble generating device 100, by connecting the bubble generating module 101 and the respirator module 102, can improve the cleaning characteristics of items and achieve gas emission. In existing respirator modules 102, the respirator module 102 is connected to the water inlet tank, which only has the function of supplying water and its cleaning effect on items is not good. However, in this embodiment, the bubble generating module 101 and the respirator module 102 are integrated into one unit, which can mix gas and liquid during water supply, thereby increasing the number of bubbles mixed in the liquid and improving the cleaning effect of items. Moreover, the bubble generating module 101 occupies the original water inlet tank without increasing the overall size of the bubble generating device 100, reducing the installation cost. Furthermore, the arrangement of the bubble generating module 101 and the respirator module 102 in a limited space results in a compact structure, complete functions, and good performance.

[0048] In some embodiments, a drainage channel 6 is also formed within the respirator module 102. The drainage channel 6 is provided with a drainage inlet 61 and a drainage outlet 62, which are respectively connected to an external waterway.

[0049] Specifically, the drainage channel 6 is used to discharge liquid, and another part of the structure of the respirator module 102 can be configured as the drainage channel 6, wherein, for example... Figure 1 and Figure 3 As shown, the drainage channel 6 is provided with a drainage inlet 61 that connects to an external water system. The drainage inlet 61 is used to discharge liquid, and the drainage channel 6 is also provided with a drainage outlet 62. The drainage channel 6 can be connected to the external water system through the drainage outlet 62. In this way, when the washing is finished, the washed wastewater enters the drainage channel 6 from the drainage inlet 61, and then flows through the drain pipe to the outside of the breather module 102, realizing the discharge of wastewater. The drainage channel 6 can serve as a central drainage pipe, and the drainage channel 6 is also connected to a drainage pump for pumping liquid flow.

[0050] Furthermore, the drainage channel 6 is connected to the exhaust space 5, which allows the gas in the exhaust space 5 to enter the drainage channel 6, replenishing the gas pressure in the drainage channel 6 to balance the pressure in the drainage channel 6 and prevent backflow in the drainage channel 6. This configuration also enables the gas in the exhaust space 5 to be recycled, improving the gas utilization rate.

[0051] The drainage inlet 61 and drainage outlet 62 can be located at the bottom of the respirator module 102 and are spaced apart, thus forming an inverted U-shaped liquid flow path. This makes the overall structure of the channel more compact and occupies less space, improving the overall integration.

[0052] In some embodiments, a connection channel 7 is also formed within the respirator module 102. The connection channel 7 has a connection inlet 71 and a connection outlet 72. The connection inlet 71 communicates with the exhaust space 5, and the connection outlet 72 communicates with the drainage channel 6.

[0053] Specifically, the connecting channel 7 is located between the exhaust space 5 and the drainage channel 6. The connecting channel 7 is connected to the exhaust space 5 through the connecting inlet 71 and to the drainage channel 6 through the connecting outlet 72. The connecting channel 7 is located on the side of the exhaust space 5 away from the dissolved gas space 12. The connecting channel 7 can be set to extend vertically, so that the gas in the exhaust space 5 can be introduced into the drainage channel 6 through the connecting channel 7.

[0054] Furthermore, during the washing process, and when the drain channel 6 drains water, a negative pressure state is formed inside the drain channel 6, which can easily create a siphon effect, causing the liquid discharged from the drain channel 6 to flow back. In this embodiment, by quickly introducing gas into the drain channel 6 through the connecting channel 7, the gas pressure inside the drain channel 6 can be replenished, thereby preventing the backflow of water during the drainage process.

[0055] The exhaust outlet 52 of the exhaust space 5 is connected to the external space. That is, when the exhaust space 5 is not venting, or when the pressure of the exhaust space 5 is lower than that of the external space, external gas can enter the exhaust space 5 through the exhaust outlet 52, and the gas entering can flow to the connecting channel 7, and can also supply gas to the connecting channel 7.

[0056] Therefore, through the above-mentioned arrangement, the gas in the external space or the exhaust space 5 can be used to enter the drainage channel 6, which can effectively replenish the gas pressure in the drainage channel 6 to balance the pressure of the drainage channel 6, thereby playing the role of preventing siphoning. Its structure is simple and its use effect is good.

[0057] The connecting channel 7 can be integrally formed with the respirator module 102, or it can be a separate pipe that is detachably connected to the respirator module 102.

[0058] In some embodiments, the connection inlet 71 is provided with a second one-way valve 73, which is configured to allow one-way flow from the exhaust space 5 to the connection channel 7, and is configured to open when the connection inlet 71 is under negative pressure.

[0059] Specifically, the second one-way valve 73 is used for one-way gas flow, such as... Figure 3As shown, the second one-way valve 73 is located at the connection inlet 71 of the connection channel 7. The second one-way valve 73 is detachably connected to the top of the connection channel 7, and the second one-way valve 73 is configured to open under the action of negative pressure at the connection inlet 71. That is, when a pressure difference is formed between the inside of the connection channel 7 and the outside space, the second one-way valve 73 is opened by the pressure difference, so that gas can flow unidirectionally from the exhaust inlet 51 to the connection inlet 71.

[0060] Furthermore, during the washing process, and when encountering the drain siphon effect, the larger external air pressure will open the second one-way valve 73, and the gas will enter the exhaust space 5 from the exhaust outlet 52 and enter the connecting channel 7 through the second one-way valve 73, so as to balance the air pressure inside the drain channel 6, thereby playing the role of preventing siphon.

[0061] Therefore, by setting a second one-way valve 73, the gas can flow in one direction and balance the air pressure between the drain channel 6 and the external space, thereby improving the stability of liquid discharge.

[0062] In some embodiments, the drainage channel 6 and the exhaust space 5 are located on the same side of the dissolved gas space 12, such as... Figure 1 and Figure 3 As shown, the drainage channel 6 and the exhaust space 5 are distributed at intervals along the vertical direction, and both are located on the same side of the dissolved air space 12. In this way, the drainage channel 6 and the exhaust space 5 occupy one side of the bubble generating device 100, and the dissolved air space 12 occupies the other side of the bubble generating device 100, realizing the integrated arrangement of the three. The space occupied by the dissolved air space 12 is larger than that of the drainage channel 6 and the exhaust space 5, so more space can be used for gas and liquid mixing to improve the gas-liquid mixture required for the washing process. The bubble generating device 100 has gas-liquid mixing function, exhaust function and drainage function at the same time. Its arrangement is reasonable and the structure is compact, which can improve the cleaning function of items.

[0063] In other embodiments, the respirator module 102 and the bubble generating module 101 are connected in the horizontal direction, that is, the respirator module 102 and the bubble generating module 101 are distributed sequentially in the horizontal direction, and both are distributed in the horizontal direction. In this way, when the respirator module 102 and the bubble generating module 101 are connected to the matching device, they can only occupy the side space of the device, making the installation more convenient and simple, the structure more compact, the space occupied less, and the integration with other devices easier.

[0064] The bubble generating device 100 can be arranged in the left-right direction, the front-back direction, or the inclined direction. Its setting direction is related to the equipment to be used, and there are various setting methods.

[0065] Furthermore, the drain channel 6 is located below the exhaust space 5, which allows the drain channel 6 to discharge the liquid in the washing space 11 more quickly, and also facilitates the discharge of gas in the washing space 11 from the exhaust space 5, so that gas is discharged from the top and liquid is discharged from the bottom, which improves the exhaust efficiency and drainage efficiency. The two do not affect each other, thereby improving the working efficiency and working stability of the washing equipment 100.

[0066] Therefore, the drainage channel 6 can occupy the lower space of the respirator module 102, and the exhaust space 5 can occupy the upper space of the respirator module 102, so as to realize drainage from the lower side and exhaust from the upper side, allowing liquids and gases to be discharged more smoothly. Through the vertical arrangement, both occupy the vertical space of the respirator module 102 without increasing the horizontal size of the respirator module 102, making the overall structure more compact.

[0067] It should be noted that the dissolved air space 12 can be integrated with the drainage channel 6 to provide bubble water to the equipment and discharge the liquid after washing. At the same time, the dissolved air space 12 can be integrated with the exhaust space 5 to provide bubble water to the equipment and discharge the gas during the washing process. Furthermore, all three can be integrated to provide bubble water to the equipment and discharge the gas and liquid inside the equipment. There are various configuration options available, which can be selected selectively.

[0068] In other embodiments, the connecting channel 7 extends vertically and is located on the side of the exhaust space 5 away from the dissolved gas space 12.

[0069] Specifically, the connecting channel 7 is located between the exhaust space 5 and the drainage channel 6. The connecting channel 7 is connected to the exhaust space 5 through the connecting inlet 71 and to the drainage channel 6 through the connecting outlet 72. The connecting channel 7 is located on the side of the exhaust space 5 away from the dissolved gas space 12. At least part of the structure of the connecting channel 7 can be arranged to extend vertically. In this way, the gas in the exhaust space 5 can be introduced into the drainage channel 6 through the connecting channel 7 along a vertical path.

[0070] This arrangement allows for faster replenishment of gas into the drainage channel 6 to compensate for the pressure within it.

[0071] Furthermore, during the washing process, and when the drain channel 6 drains water, a negative pressure state is formed inside the drain channel 6, which can easily create a siphon effect, causing the liquid discharged from the drain channel 6 to flow back. In this embodiment, by quickly introducing gas into the drain channel 6 through the connecting channel 7, the gas pressure inside the drain channel 6 can be replenished, thereby preventing the backflow of water during the drainage process.

[0072] In some embodiments, the air inlet 13 is connected to the exhaust space 5, the exhaust outlet 52 is located above the exhaust inlet 51, and the air inlet 13 and the exhaust outlet 52 are spaced apart in the horizontal direction.

[0073] Specifically, such as Figure 1 and Figure 3 As shown, the exhaust inlet 51 and exhaust outlet 52 are spaced apart in the vertical direction. The exhaust inlet 51 can be located in the middle area of ​​the respirator module 102, and the exhaust outlet 52 can be located in the top area of ​​the respirator module 102. In this way, the exhaust inlet 51 can be connected to the upper area of ​​the washing chamber of the equipment, so that the gas in the washing chamber can enter the exhaust space 5 through the exhaust inlet 51, and be discharged from the respirator module 102 from bottom to top through the exhaust outlet 52 in the exhaust space 5, thereby realizing the gas discharge.

[0074] Therefore, by setting the exhaust inlet 51 in the middle region of the respirator module 102, it is beneficial to discharge the gas in the washing chamber and reduce the probability of liquid in the washing chamber entering the exhaust space 5, thereby keeping the liquid in the washing chamber sufficient and ensuring the cleaning characteristics. Furthermore, by setting the exhaust outlet 52 above the exhaust inlet 51, the liquid in the washing chamber will not flow upward due to its own gravity after entering the exhaust inlet 51, thereby reducing the possibility of liquid discharge. The setting is reasonable and the gas discharge is smooth.

[0075] Furthermore, the exhaust outlet 52 and the air intake 13 are horizontally spaced apart, such as... Figure 1 As shown, the exhaust outlet 52 passes through the respirator module 102 and is directly connected to the external space. The air inlet 13 is spaced apart from the exhaust outlet 52, and the air inlet 13 does not directly pass through the respirator module 102. External air can enter the exhaust space 5 through the exhaust outlet 52. When the air inlet 13 is opened, the gas at the exhaust outlet 52 can flow to the air inlet 13 and then flow into the air intake channel 3. At the same time, when the exhaust space 5 needs to discharge gas, the gas in the exhaust space 5 is discharged from the respirator module 102 through the exhaust outlet 52. The direction of gas flow is not unique and can be selectively adjusted according to the working status of the equipment.

[0076] Furthermore, the exhaust outlet 52 and the air inlet 13 are arranged horizontally at intervals. During the exhaust process, exhaust is carried out through the exhaust outlet 52, and the exhaust is smooth and not subject to the resistance of the air inlet. In addition, only one connection hole to the external space is provided, which makes the overall structure simpler and easier to use.

[0077] Furthermore, the air inlet 13 is connected to the exhaust space 5, so that the gas in the exhaust space 5 can enter the dissolved gas space 12 or the air intake channel 3 through the air inlet 13, thereby providing gas to the Venturi pipe 2 and realizing the recycling of gas in the exhaust space 5, thus improving the gas utilization rate.

[0078] In some embodiments, the exhaust space 5 is provided with a plurality of baffles 53, the extension direction of which intersects the arrangement direction of the exhaust inlet 51 and the exhaust outlet 52.

[0079] Specifically, the exhaust space 5 is provided with multiple baffles 53 to block the gas in the exhaust space 5. The multiple baffles 53 are spaced apart between the exhaust inlet 51 and the exhaust outlet 52. The extension direction of the baffles 53 intersects the arrangement direction of the exhaust inlet 51 and the exhaust outlet 52. The exhaust inlet 51 and the exhaust outlet 52 are distributed in the vertical direction. The extension direction of the baffles 53 can be in the horizontal direction, that is, the extension direction of the baffles 53 is perpendicular to the vertical direction, or it can be set in a non-vertical direction. There are various ways to set them.

[0080] like Figure 2 and Figure 3 As shown, the baffle ribs 53 located in the middle region of the exhaust space 5 are arc-shaped, while the baffle ribs 53 located on both sides of the exhaust space 5 are linear. The two ends of the arc-shaped baffle ribs 53 are open towards the exhaust inlet 51, and the linear baffle ribs 53 extend in the direction of the arc-shaped baffle ribs 53. When the gas in the exhaust inlet 51 flows from bottom to top, the multiple baffle ribs 53 can block the gas multiple times, allowing the gas to flow along a certain path and increasing the gas flow path.

[0081] Therefore, by setting multiple baffles 53, the length and resistance of the gas flow channel within the exhaust space 5 can be increased. This allows the gas to form water droplets as it flows past the baffles 53, thereby increasing the condensation rate of water vapor and reducing the amount of condensate discharged. Furthermore, the multiple baffles 53, supported and connected within the exhaust space 5, can improve the structural strength of the exhaust space 5.

[0082] In some embodiments, the bubble generating device 100 further includes a Venturi tube 2, which is provided with an air inlet 21, a liquid inlet 22 and a mixing outlet 23. The air inlet 21 is connected to the air inlet 13, the liquid inlet 22 is connected to the liquid inlet 14, and the mixing outlet 23 is connected to the dissolved gas space 12.

[0083] Specifically, such as Figure 1As shown, an air inlet 21 can be provided in the inlet area of ​​the Venturi pipe 2, and the air inlet 21 is connected to the air inlet 13, so that the external space can be connected to the Venturi pipe 2 to realize the flow of gas. A liquid inlet 22 can be provided in the inlet area of ​​the Venturi pipe 2, and the liquid inlet 22 is connected to the liquid inlet 14, so that the liquid inlet 14 is connected to the Venturi pipe 2 to realize the flow of liquid. A mixing outlet 23 can be provided in the outlet area of ​​the Venturi pipe 2, and the mixing outlet 23 is connected to the dissolved gas space 12, so that the Venturi pipe 2 and the dissolved gas space 12 can be connected.

[0084] Furthermore, external gas enters the dissolved gas space 12 through the air inlet 13, and the gas enters the Venturi pipe 2 through the air inlet 21. At the same time, the liquid at the liquid inlet 14 enters the Venturi pipe 2 through the liquid inlet 22. After the gas and liquid are mixed in the Venturi pipe 2, they enter the dissolved gas space 12 through the mixing outlet 23, where the mixing of gas and liquid continues.

[0085] It should be noted that the Venturi pipe 2 has a Venturi structure inside, and the cross-section of the Venturi structure can be set to gradually decrease and then gradually increase from the inlet area to the outlet area of ​​the Venturi pipe 2. This allows a vacuum area to be formed inside the Venturi pipe 2 when the liquid passes through the narrow channel. The water flow can draw in the gas inside the Venturi pipe 2, mixing the liquid and gas for the first time. After mixing, the gas and liquid enter the dissolved gas space 12 for a second mixing, thereby improving the mixing characteristics of the liquid and gas.

[0086] The Venturi pipe 2 can be integrally formed with the bubble generator 100, or it can be a separate pipe that is detachably connected to the bubble generator 100.

[0087] In some embodiments, the bubble generating module 101 also has an air intake channel 3, which is connected between the air intake hole 21 and the air intake port 13.

[0088] Specifically, the air inlet 13 is connected to the dissolved gas space 12, one end of the air inlet channel 3 is connected to the air inlet 13, and the other end is connected to the air inlet 21. In this way, the gas at the air inlet 13 can be introduced into the air inlet 21 through the air inlet channel 3, and the dissolved gas space 12 can be connected to the Venturi pipe 2 through the air inlet channel 3, so that the air in the dissolved gas space 12 can be introduced into the Venturi pipe 2 through the air inlet channel 3, and gas can be introduced into the Venturi pipe 2.

[0089] This configuration allows external air to be directly introduced into the Venturi pipe 2 through the air intake channel 3, and also allows gas in the dissolved gas space 12 to be introduced into the Venturi pipe 2. This improves the air supply mode of the Venturi pipe 2 and allows the remaining gas in the dissolved gas space 12 to be recycled, thereby improving the air utilization rate of the overall system and thus improving the thorough mixing of gas and liquid.

[0090] The air intake channel 3 can be integrally formed with the bubble generating module 101, or it can be a separate pipe that is detachably connected to the bubble generating module 101.

[0091] In some other embodiments, a liquid inlet channel 4 is also formed in the bubble generating module 101, which is connected between the liquid inlet hole 22 and the liquid inlet 14.

[0092] Specifically, the liquid inlet channel 4 is located upstream of the Venturi pipe 2. One end of the liquid inlet channel 4 is connected to the liquid inlet 14, and the other end is connected to the liquid inlet hole 22. In this way, liquid at the liquid inlet 14 can be introduced into the liquid inlet hole 22 through the liquid inlet channel 4, thus introducing liquid into the Venturi pipe 2. The liquid inlet 14 of the liquid inlet channel 4 can be connected to a tap water pipe or to a water tank provided by the bubble generating module 101 itself. The liquid inlet channel 4, the Venturi pipe 2, and the dissolved gas space 12 are connected sequentially along the liquid flow direction. In this way, tap water or water stored in the water tank can flow into the Venturi pipe 2 through the liquid inlet channel 4, and the liquid and gas are fully mixed in the Venturi pipe 2 and the dissolved gas space 12. The mixed gas-liquid mixture is then introduced into the washing chamber of the equipment.

[0093] Therefore, through the above settings, it is possible to achieve the mixing of gas and liquid during the water supply process to the washing chamber of the equipment, and to provide the washing chamber with liquid containing gas, thereby improving the cleaning characteristics of the washed items.

[0094] The liquid inlet channel 4 can be integrally formed with the bubble generating module 101, or it can be a separate pipe that is detachably connected to the bubble generating module 101.

[0095] In some embodiments, the air intake channel 3 extends in the vertical direction, the inlet end of the air intake channel 3 is connected to the top of the dissolved gas space 12, and the outlet end of the air intake channel 3 extends to the air inlet 21 of the venturi pipe 2.

[0096] Specifically, the top of the air intake channel 3 is connected to the top of the dissolved gas space 12, and at least part of the air intake channel 3 extends downward. Arc-shaped channels can be provided in the top region of the air intake channel 3 and the connection between the air intake channel 3 and the Venturi pipe 2, so that the air intake channel 3 is distributed outside the first dissolved gas region 123 of the dissolved gas space 12, and the air intake channel 3 and the first dissolved gas region 123 are arranged side by side in the horizontal direction. The gas that has not participated in the fusion at the top of the dissolved gas space 12 can be passed downward into the Venturi pipe 2 through the air intake channel 3 to realize the recycling of gas. Moreover, the air intake channel 3 occupies less space, and the overall structure is compact and more integrated.

[0097] Furthermore, the air intake channel 3 is arranged side by side with the first dissolved gas area 123 in the horizontal direction. The air intake channel 3 is a separate channel, which can allow the gas at the top of the first dissolved gas area 123 and the gas entering from the external space to be introduced into the Venturi pipe 2, thereby increasing the air intake volume of the Venturi pipe 2.

[0098] In some embodiments, the inlet channel 4 is connected to the lower part of the Venturi conduit 2, such as when the inlet channel 4 can be detachably connected to the Venturi conduit 2. Figure 1 and Figure 3 As shown, the Venturi tube 2 extends vertically, and its lower end connects to the liquid inlet channel 4, allowing liquid to flow from bottom to top into the Venturi tube 2 along the liquid inlet channel 4. The liquid inlet channel 4 is also provided to store a certain amount of liquid during the washing process, ensuring stable mixing of liquid and gas within the Venturi tube 2. A water pump can be installed in the liquid inlet channel 4 to transport the liquid.

[0099] Furthermore, the liquid inlet channel 4 is located at the lower part of the venturi pipe 2, which allows the two to be distributed vertically. This can occupy the vertical space of the bubble generating module 101, making the overall structure more compact and reasonable, and effectively improving the utilization rate of the internal space of the bubble generating module 101.

[0100] In other embodiments, the dissolved gas space 12 is connected to the upper end of the Venturi conduit 2, such as... Figure 1 and Figure 3 As shown, the dissolved gas space 12 is distributed in the vertical direction, and the upper region of the dissolved gas space 12 is connected to the upper end of the Venturi pipe 2, which allows the gas and liquid mixture in the Venturi pipe 2 to enter the upper region of the dissolved gas space 12. The gas and liquid continue to mix in the dissolved gas space 12 and flow vertically downward, which can increase the flow rate of the gas-liquid mixture, thereby increasing the speed of liquid delivery to the washing space 11, so as to improve the cleaning efficiency and cleaning quality of the items.

[0101] Furthermore, the dissolved gas space 12 is connected to the upper end of the Venturi pipe 2, which allows the gas-liquid mixture in the dissolved gas space 12 to increase its flow rate by gravity. Moreover, the liquid flows upward first and then downward, which can utilize the vertical space on the same side as the bubble generating module 101, making the overall structure more compact and reasonable.

[0102] In other embodiments, the air intake passage 3 is connected to the peripheral wall of the venturi pipe 2, such as... Figure 1 and Figure 3 As shown, the air intake channel 3 can extend vertically, and the outlet end of the air intake channel 3 extends to the air intake hole 21 in the inlet area of ​​the outer periphery of the Venturi pipe 2. The inlet end of the air intake channel 3 is connected to the top of the dissolved gas space 12. In this way, the unmixed gas in the dissolved gas space 12 can flow from the top of the dissolved gas space 12 into the air intake channel 3 and then into the Venturi pipe 2 to realize the recycling of gas.

[0103] Furthermore, the liquid inlet channel 4 is connected to the liquid inlet hole 22 at the bottom of the venturi pipe 2, which can separate the air inlet channel 3 and the liquid inlet channel 4 to achieve air intake on the outer periphery and water intake at the bottom respectively. This arrangement separates the air intake and water intake structures and prevents them from affecting each other.

[0104] The air intake channel 3 is located on the right side of the Venturi pipe 2, and the dissolved air space 12 is located on the left side of the Venturi pipe 2. This separates them so that they can achieve different functions, and the arrangement is reasonable and will not interfere with each other.

[0105] In some embodiments, a flow meter 8 is provided in the liquid inlet channel 4. In this embodiment, the flow meter 8 is used to measure the flow rate of the liquid. The flow meter 8 can measure the flow rate of the fluid in the pipe by utilizing the form of fluid movement according to the physical laws of the fluid, so as to facilitate understanding the real-time liquid flow rate.

[0106] For example, the flow meter 8 is detachably connected to the liquid inlet channel 4. During use, after liquid is introduced into the liquid inlet channel 4, the flow meter 8 can detect the amount of water entering the liquid inlet channel 4. The flow meter 8 can accurately measure the flow rate of the fluid and provide accurate flow data to ensure that the amount of water entering the channel meets the design requirements. It can also monitor the liquid flow rate of the liquid inlet channel 4 in real time and adjust and control the flow rate as needed, which helps to ensure the uniformity and stability of the liquid-gas mixing process.

[0107] In some embodiments, the air inlet channel 3 is located above the liquid inlet channel 4, such as... Figure 1 As shown, the air inlet channel 3 and the liquid inlet channel 4 are connected to the Venturi pipe 2 separately, so that water and air can be introduced respectively.

[0108] Therefore, by setting the air inlet channel 3 above the liquid inlet channel 4, the gas in the dissolved gas space 12 can enter the upper air inlet channel 3 from the top, which is conducive to introducing the gas into the Venturi pipe 2. And by setting the liquid inlet channel 4 below, the liquid can flow from bottom to top into the Venturi pipe 2. In this way, after the liquid flows into the dissolved gas space 12 from the Venturi pipe 2, it mixes with the gas in the dissolved gas space 12. It can also squeeze the gas that has not participated in the fusion process upward and squeeze the unfused gas into the air inlet channel 3, so that the gas can circulate to the Venturi pipe 2 to continue to participate in the mixing of gas and liquid. Its setting method is more reasonable and simple, improves the gas circulation speed, and improves the gas utilization rate.

[0109] Furthermore, the liquid inlet channel 4 is located below the Venturi pipe 2, and the air inlet channel 3 and the liquid inlet channel 4 are spaced apart. This allows liquid to flow from bottom to top into the Venturi pipe 2 via the liquid inlet channel 4, and gas to flow from top to bottom into the Venturi pipe 2 via the air inlet channel 3, thus achieving mixing of gas and liquid in the Venturi pipe 2. The gas and liquid entry paths are separated to achieve separate air intake from the periphery and water intake from the bottom. The air inlet channel 3 allows unmixed gas from the dissolved gas space 12 to flow from the top of the dissolved gas space 12 into the air inlet channel 3, and then into the Venturi pipe 2, achieving gas recycling. Therefore, through the above arrangement, the air intake and water intake structures are separated and do not interfere with each other.

[0110] In some embodiments, a first one-way valve 31 is provided in the dissolved air space 12. The first one-way valve 31 is configured to conduct unidirectionally from the air inlet 13 to the dissolved air space 12, and the first one-way valve 31 is configured to open under the action of negative pressure at the air inlet 21.

[0111] Specifically, the first one-way valve 31 is used for one-way gas flow, such as... Figure 2 As shown, the first one-way valve 31 is located at the top of the dissolved gas space 12 and at the inlet end of the air inlet channel 3. The first one-way valve 31 is detachably connected to the top of the dissolved gas space 12 and is located near the air inlet 13. When the air inlet channel 3 is under negative pressure, a pressure difference can be formed between the dissolved gas space 12 and the external space, so that the first one-way valve 31 is opened by the pressure difference. In this way, gas can flow unidirectionally from the air inlet 13 to the air inlet 21.

[0112] Furthermore, during water intake, the first one-way valve 31 is in a closed state, and the dissolved air space 12 forms a sealed space. After the water intake is completed, the water inside the dissolved air space 12 flows downward by gravity, making the pressure inside the dissolved air space 12 less than the external pressure. The first one-way valve 31 opens through the air pressure difference, and external gas enters the dissolved air space 12 and the air intake channel 3 through the air inlet 13 via the first one-way valve 31, thereby supplying gas to the Venturi pipe 2, which can realize the next step of gas and liquid mixing.

[0113] Furthermore, when water enters the liquid inlet channel 4 and a negative pressure is formed inside the dissolved gas space 12, a siphon effect is easily formed. At this time, the larger external air pressure will open the first one-way valve 31, and the gas will flow into the dissolved gas space 12 to balance the pressure difference, thereby playing the role of preventing siphoning.

[0114] Therefore, by setting the first one-way valve 31, the gas can flow in one direction and continuously supply gas to the air inlet channel 3, avoiding the gas reverse flow from affecting the mixing of gas and liquid, thereby improving the stability of gas delivery.

[0115] In some embodiments, the liquid inlet 14 and the liquid outlet 15 are both located at the bottom of the bubble generating module 101, and the liquid inlet 14 and the liquid outlet 15 are spaced apart. In this way, the liquid can flow from the bottom of the bubble generating module 101 upwards into the liquid inlet channel 4, the Venturi tube 2 and the dissolved gas space 12 in sequence, and the gas-liquid mixture in the dissolved gas space 12 flows downwards to the bottom of the bubble generating module 101, forming an inverted U-shaped flow path. This makes the distribution of multiple channels more compact and occupies less space, thus improving the overall integration.

[0116] The inlet 14 and outlet 15 are both located at the bottom of the dissolved gas space 12. The inlet channel 4 is constructed to extend upward relative to the inlet 14 and communicate with the dissolved gas space 12. In this way, the liquid can flow upward from the inlet 14 at the bottom through the inlet channel 4 into the dissolved gas space 12, where it mixes with the gas. The mixed liquid and gas in the dissolved gas space 12 then flow out towards the outlet 15 at the bottom. The low position of the inlet 14 and outlet 15 allows the liquid to rise a certain distance before flowing downward, which is beneficial for the liquid and gas to flow in the dissolved gas space 12 by their own gravity. This results in greater kinetic energy for the liquid flowing downward, thereby increasing the flow speed of the liquid.

[0117] Furthermore, the liquid outlet 15 is located at the bottom of the bubble generating module 101, which can utilize the gravity of the liquid to increase its flow rate and improve the cleaning speed of the items. It also allows the liquid containing bubbles to enter the washing chamber from the bottom of the bubble generating module 101, improving the stability of the liquid flow, reducing the possibility of liquid splashing, and improving the cleanliness of the cleaning.

[0118] It should be noted that the dissolved air space 12 is provided with a turbulence structure 121, which is configured to guide the mixed liquid first toward a direction away from the liquid outlet 15 and then toward the liquid outlet 15.

[0119] In other words, the turbulence structure 121 can guide the mixed liquid away from the outlet 15 first, and after the distance between the mixed liquid and the outlet 15 is greater, the turbulence structure 121 can guide the mixed liquid closer to the outlet 15, so that the flow direction of the mixed liquid is U-shaped in the opposite direction. In this way, the turbulence structure 121 can make the mixed liquid flow along the U-shaped path in the dissolved air space 12. The distance between the mixed liquid and the outlet 15 is greater, the kinetic energy of the mixed liquid is greater, and the flow speed of the mixed liquid is also faster. Compared with directly guiding the mixed liquid towards the outlet 15, the flow path of the mixed liquid is increased, which can make the mixed liquid fully blended in the dissolved air space 12 and then flow from the outlet 15 to the bubbler 9. This increases the amount of bubbles generated by the bubble generating module 101, which is beneficial to improving the cleaning characteristics of the items.

[0120] Furthermore, the turbulence structure 121 provided in the dissolved gas space 12 can turbulently flow the liquid and gas entering the dissolved gas space 12, thereby changing the flow direction of the gas and liquid. This allows the gas and liquid to be fully mixed within the dissolved gas space 12, and the resulting gas-liquid mixture flows out from the liquid outlet 15, thus achieving pre-mixing of the gas and liquid. Moreover, the turbulence structure 121, located within the limited space of the dissolved gas space 12, facilitates thorough mixing of the gas and liquid under the impact and reflection of the turbulence structure 121, improving cleaning quality. The structure is also simple to design and its function is easy to implement.

[0121] In some embodiments, the turbulence structure 121 includes a first turbulence rib 1211 and a second turbulence rib 1212, and a turbulence channel 1213 is defined between the first turbulence rib 1211 and the second turbulence rib 1212.

[0122] Specifically, at least one of the first and second baffle ribs 1211 and 1212 can be provided. The first and second baffle ribs 1211 and 1212 are intersecting, meaning they are connected intersectingly. They can be connected perpendicularly or non-perpendicularly. A baffle channel 1213 is defined between at least one first baffle rib 1211 and at least one second baffle rib 1212, allowing gas and liquid to flow along the baffle channel 1213. Through at least one reflection and impact from at least one first baffle rib 1211 and at least one second baffle rib 1212, the gas and liquid are thoroughly mixed, thereby improving the ability of the gas-liquid mixture to clean stains and thus improving the cleaning effect. The baffle channel 1213 connects the mixing inlet 122 and the outlet 15, allowing the mixed gas-liquid mixture to flow through the baffle channel 1213 to the outlet 15.

[0123] Furthermore, the first bleed rib 1211 and the second bleed rib 1212 can also be distributed at intervals.

[0124] In some embodiments, the turbulence channel 1213 includes a plurality of turbulence segments 1214, and at least two of the plurality of turbulence segments 1214 have intersecting directions of extension.

[0125] Specifically, a turbulence channel 1213 is formed between the first turbulence rib 1211 and the second turbulence rib 1212. The turbulence channel 1213 includes multiple turbulence sections 1214, which are connected in sequence. At least two turbulence sections 1214 extend in different directions and can be distributed vertically or non-vertically. This allows the flow direction of the gas and liquid to change, that is, the gas and liquid flow in different directions within the multiple turbulence sections 1214, increasing the flow path length and facilitating the full fusion of the gas and liquid under impact.

[0126] In some embodiments, at least one first baffle 1211 extends and bends in both the horizontal and vertical directions, surrounding the mixing inlet 122 to separate the mixing inlet 122 from the air inlet 13. That is, one first baffle 1211 can be provided between the mixing inlet 122 and the air inlet 13, or multiple first baffle 1211 can be provided. Both of these arrangements can separate the mixing inlet 122 from the air inlet 13 through the first baffle 1211, thereby preventing the liquid at the mixing inlet 122 from flowing directly to the air inlet 13, and allowing the liquid at the mixing inlet 122 to flow into the dissolved air space 12 through the guidance of the first baffle 1211.

[0127] like Figure 1 As shown, a first baffle 1211 is provided at the mixing inlet 122 of the dissolved air space 12. The first baffle 1211 separates the mixing inlet 122 from the air inlet 13, and the shape of the first baffle 1211 is L-shaped, that is, the first baffle 1211 can be bent in both horizontal and vertical directions, so that the first baffle 1211 surrounds the mixing inlet 122 and separates the mixing inlet 122 from the air inlet 13. In this way, the gas and liquid entering the dissolved air space 12 can be prevented from directly impacting the air inlet 13, causing the air inlet 13 to fail to seal, thereby improving the sealing characteristics of the air inlet 13 and improving the reliability and stability of the water intake process. Thus, by setting the first baffle 1211, the liquid at the mixing inlet 122 can be guided, and the liquid can be prevented from directly impacting the air inlet 13 at the top of the dissolved air space 12, and the sealing performance of the air inlet 13 can also be guaranteed. The structure is simple and the effect is good.

[0128] Furthermore, the first baffle 1211 and the second baffle 1212 can be integrally formed with the bubble generating module 101, or they can be glued or welded to the bubble generating module 101. Its structure is simple, easy to process, and its functions are easy to implement.

[0129] The first baffle 1211 and the second baffle 1212 can be one, two, three, four, etc., and the number of the first baffle 1211 and the second baffle 1212 can be the same or different. It is not limited to the embodiment described in this example, and can be selectively set according to the actual space size.

[0130] In some embodiments, at least one first bleed rib 1211 extends in both horizontal and vertical directions, surrounding the mixing inlet 122 to separate it from the air inlet 13. This forms an L-shaped bleed channel 1213, allowing gas and liquid to flow horizontally and vertically under the guidance of the first bleed rib 1211, thus changing the flow direction of the liquid and gas. A second bleed rib 1212 can extend horizontally, forming different bleed sections 1214 extending vertically and horizontally respectively, thus forming a curved bleed channel 1213 and extending its length. Its structure is simple, easy to manufacture, and its function is readily implemented.

[0131] Furthermore, the first turbulence rib 1211 is L-shaped, so that the first turbulence rib 1211 surrounds the mixing inlet 122 and separates the mixing inlet 122 from the air inlet 13. In this way, the gas and liquid entering the dissolved gas space 12 can be prevented from directly impacting the air inlet 13 and causing the air inlet 13 to fail to seal. This improves the sealing characteristics of the air inlet 13 and also improves the reliability and stability of the water intake process.

[0132] The liquid inlet 14 and the liquid outlet 15 are both located at the bottom of the dissolved gas space 12, and the liquid inlet channel 4 is constructed to extend upward relative to the liquid inlet 14 to communicate with the dissolved gas space 12.

[0133] In this way, the liquid can flow upward from the bottom inlet 14 through the inlet channel 4 into the dissolved gas space 12, where it mixes with the gas. The mixed liquid and gas in the dissolved gas space 12 then flow out towards the bottom outlet 15. The inlet 14 and outlet 15 are positioned low, allowing the liquid to rise a certain distance before flowing downward. This facilitates the flow of the liquid and gas in the dissolved gas space 12 by gravity, resulting in greater downward kinetic energy for the liquid and thus increasing the flow speed of the liquid.

[0134] Specifically, the inlet 14 and the outlet 15 are spaced apart and located at the bottom of the dissolved gas space 12. The inlet channel 4 is located between the inlet 14 and the dissolved gas space 12, and the inlet channel 4 extends upward. The end of the inlet channel 4 away from the inlet 14 is connected to the dissolved gas space 12, so that the inlet channel 4 and the dissolved gas space 12 can be connected.

[0135] Furthermore, when the bubble generator 100 is working, the air inlet 13 is closed. At this time, due to the strong pressure of the liquid, no more gas can be injected. Therefore, it is necessary to make fuller use of the gas already inside the dissolved air space 12. After the liquid inlet 14 is opened, the liquid flows into the liquid inlet channel 4 and the dissolved air space 12. The gas in the dissolved air space 12 will be discharged from the liquid outlet 15 along with the liquid, resulting in a reduction in the gas content in the dissolved air space 12, which in turn leads to a significant reduction in the final bubble effect. By setting the liquid outlet 15 at the bottom of the dissolved air space 12, when the liquid is initially introduced into the dissolved air space 12, there is less liquid in the dissolved air space 12. The liquid will flow quickly from top to bottom to the liquid outlet 15 by gravity, forming a water seal above the liquid outlet 15. When the liquid quickly forms a water seal on the liquid outlet 15, the possibility of gas being discharged from the dissolved air space 12 can be reduced. Moreover, as the liquid is continuously transported, the remaining liquid mixes with the gas in the dissolved air space 12, and the mixed gas and liquid flow out of the liquid outlet 15.

[0136] According to an embodiment of the present invention, the bubble generating device 100 provides a dissolved gas space 12 in the bubble generating module 1, so that the liquid before entering the bubbler 9 is fully mixed with the gas in the dissolved gas space 12. The outlet 15 and the inlet 14 are located at the bottom of the dissolved gas space 12, and the inlet channel 4 is configured to extend upward relative to the inlet 14 to communicate with the dissolved gas space 12. This allows the liquid to flow upward into the dissolved gas space 12 and out from the outlet 15 at the bottom. A water seal is quickly formed at the outlet 15, which can trap more gas in the dissolved gas space 12. This facilitates the full mixing of the liquid and gas in the dissolved gas space 12, forming a large amount of liquid containing bubbles. This improves the cleaning properties of the items and enhances the user experience.

[0137] In some embodiments, the dissolved gas space 12 includes a first dissolved gas region 123 and a second dissolved gas region 124. The first dissolved gas region 123 is located above the second dissolved gas region 124. The air inlet 13 and the liquid inlet 14 are both connected to the first dissolved gas region 123, and the liquid outlet 15 is located at the bottom of the second dissolved gas region 124.

[0138] Specifically, the dissolved gas space 12 includes two parts, namely a first dissolved gas region 123 and a second dissolved gas region 124. The dissolved gas space 12 extends in the vertical direction, and the first dissolved gas region 123 is connected to the upper side of the second dissolved gas region 124. The liquid inlet 14 and the air inlet 13 can be connected to the first dissolved gas region 123 through different pipes, so that the air inlet 13 and the liquid inlet 14 are respectively connected to the dissolved gas space 12. In this way, both liquid and gas can enter the first dissolved gas region 123. The liquid outlet 15 is connected to the side of the second dissolved gas region 124 away from the first dissolved gas region 123, that is, the liquid outlet 15 is located at the bottom of the second dissolved gas region 124, so that the liquid and gas in the second dissolved gas region 124 are discharged from the liquid outlet 15 at the bottom.

[0139] Furthermore, the gas entering through the air inlet 13 and the liquid entering through the liquid inlet 14 simultaneously enter the first dissolved gas region 123. Some of the liquid flows downwards due to its own gravity and can quickly reach the bottom of the second dissolved gas region 124, reaching the position above the liquid outlet 15, which can form a water seal on the liquid outlet 15. The remaining liquid mixes with the gas in the first dissolved gas region 123 and the second dissolved gas region 124, and the mixed gas and liquid flow out of the liquid outlet 15.

[0140] In some embodiments, the cross-sectional area of ​​the second dissolved gas region 124 is smaller than that of the first dissolved gas region 123. This allows the first dissolved gas region 123 to have a larger cross-sectional area, which can accommodate more gas and liquid and allows most of the liquid and gas to mix within the first dissolved gas region 123, thus improving the mixing of gas and liquid within the dissolved gas space 12. The smaller cross-sectional area of ​​the second dissolved gas region 124 also allows for some mixing of gas and liquid, and the smaller cross-sectional area allows the gas and liquid mixture to accumulate, thereby increasing the flow rate of the gas-liquid mixture and the discharge rate of gas and liquid, thus improving the efficiency of gas-liquid mixture production and the efficiency of cleaning items.

[0141] Furthermore, the second dissolved gas region 124 is located below the first dissolved gas region 123. The cross-sectional area of ​​the second dissolved gas region 124 is smaller than that of the first dissolved gas region 123. The cross-sectional area can be designed to gradually decrease from the first dissolved gas region 123 to the second dissolved gas region 124, meaning the flow path of liquid and gas within the dissolved gas space 12 gradually narrows. This increases the flow velocity of the liquid in the initial stage of water inflow, facilitating its rapid flow to the outlet 15 due to gravity. A water seal is formed at the outlet 15, preventing the liquid from carrying too much gas out of the outlet during the initial water inflow stage. This effectively traps most of the gas within the dissolved gas space 12, improving gas utilization. Simultaneously, the rapid water seal accelerates bubble generation. The small cross-sectional area of ​​the second dissolved gas region 124 also reduces its space requirement, facilitating the installation of other structures.

[0142] The present invention also proposes a washing device.

[0143] According to an embodiment of the present invention, a washing device includes: a main body and a bubble generating device 100 of any of the above embodiments. A washing space is formed in the main body. The main body is provided with a foamer 9 connected to the washing space. A liquid outlet 15 is connected to the foamer 9. An exhaust inlet 51 is connected to the washing space.

[0144] Specifically, the main body of the equipment is the core structure of the washing equipment, supporting the internal structures and allowing for the installation of different structures. A washing space is formed within the main body to realize the washing function. This washing equipment can be a dishwasher, washing machine, or similar appliance to achieve different cleaning functions. The washing space can be constructed as an open cavity structure for users to place items to be washed, and can be open to the top or front for easy operation by the user in front of the washing equipment.

[0145] The main body of the device is equipped with an aerator 9, which mixes water and air to generate bubbles for effective cleaning of items. A liquid outlet 15 is connected to the aerator 9, allowing the dissolved air space 12 to connect with it. This allows the pre-mixed gas-liquid mixture in the dissolved air space 12 to be introduced into the aerator 9 through the liquid outlet 15. Within the aerator 9, the mixture is further separated into liquid containing microbubbles, which can then be used for washing items. Furthermore, the aerator 9 is connected to the washing space 11, allowing the liquid containing microbubbles generated by the aerator 9 to be introduced into the washing space 11 to clean the items within it.

[0146] Furthermore, the exhaust inlet 51 is connected to the washing space, allowing the gas in the washing space to be introduced into the exhaust space 5 through the exhaust inlet 51 and discharged from the exhaust outlet 52 outside the washing equipment. This reduces the pressure in the washing space, improves the safety and stability of cleaning items, and has a reasonable and reliable structure.

[0147] Therefore, by setting a bubble generating module 101 and a breather module 102 in the bubble generating device 100, gas and liquid can be mixed in the bubble generating module 101 for the washing function of the equipment, and the internal gas of the equipment can be discharged in the breather module 102 for breathing inside the equipment, maintaining the internal and external pressure balance. Moreover, the bubble generating module 101 and the breather module 102 are integrated into one unit, realizing the arrangement of the two in a limited space. The structure is more compact, the function is more complete, and the use effect is better, thereby improving the user experience.

[0148] The mounting body 1 can be detachably connected to the equipment body by bolts, or by snap-fit ​​or plug-in connection, so that the bubble generator 100 can be disassembled and installed separately from the equipment body, which facilitates subsequent maintenance and inspection. In addition, the mounting body 1 can be integrally formed with the equipment body, reducing the connection steps between the two and reducing installation costs.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0150] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
