[0038] As Figures 1-3 shown, the bubble generating device 100 according to one embodiment of the utility model comprises a bubble generating module 101 and a breather module 102.

[0039] The bubble generating module 101 is provided with a gas dissolving space 12, an air inlet 13, a liquid inlet 14 and a liquid outlet 15 which are communicated with the gas dissolving space 12 respectively. The liquid entering through the liquid inlet 14 and the gas entering through the air inlet 13 are suitable for being mixed in the gas dissolving space 12 and flowing out from the liquid outlet 15.

[0040] Specifically, a part of the bubble generating module 101 can be formed as the gas dissolving space 12, which is used for realizing the mixing of the liquid and the gas. The bubble generating module 101 is provided with the liquid inlet 14 and the liquid outlet 15. The liquid inlet 14 is used for introducing the liquid, and the liquid outlet 15 is used for discharging the liquid. The bubble generating module 101 is also provided with the air inlet 13, which is used for communicating with the external space to introduce the gas. The liquid inlet 14, the air inlet 13 and the liquid outlet 15 are communicated with the gas dissolving space 12 respectively. In this way, the gas outside the bubble generating module 101 can enter the gas dissolving space 12 through the air inlet 13, and the liquid can enter the gas dissolving space 12 through the liquid inlet 14. The gas and the liquid are mixed in the gas dissolving space 12 to form a gas-liquid mixture, which flows out from the liquid outlet 15 to realize the pre-mixing of the gas and the liquid. The air inlet 13 is provided to facilitate the introduction of the external gas into the gas dissolving space 12, which can provide more gas for the mixing of the gas and the liquid to improve the gas-liquid mixing efficiency.

[0041] And the liquid wrapped with the bubbles formed by the gas-liquid mixture pre-mixed in the gas dissolving space 12 can be used for washing the articles, and the more bubbles the gas dissolved with the liquid in the gas dissolving space 12, the better the washing effect of the articles.

[0042] And the liquid outlet 15 is communicated with the bubbler 9, wherein the bubbler 9 is used for mixing the water and the air to generate the bubbles for effectively washing the articles to be cleaned, and the communication between the liquid outlet 15 and the bubbler 9 can make the gas dissolving space 12 communicated with the bubbler 9, so that the gas-liquid mixture pre-mixed in the gas dissolving space 12 can be introduced into the bubbler 9 through the liquid outlet 15, and the liquid wrapped with the ultra-micro bubbles can be used for washing the articles.

[0043] The respirator module 102 is connected with the bubble generating module 101, and the gas discharging space 5 is formed in the respirator module 102, and the gas discharging space 5 is provided with a gas inlet 51 and a gas outlet 52, and the gas inlet 51 and the gas outlet 52 are respectively communicated with the outside space.

[0044] Specifically, the respirator module 102 is connected with the bubble generating module 101, so that the respirator module 102 and the bubble generating module 101 are integrated into an integrated structure, that is, the gas and the liquid can be dissolved in the bubble generating module 101 for the washing function of the equipment, and the gas in the equipment can be discharged in the respirator module 102, so that the structure is more compact and the function is more perfect.

[0045] The gas discharging space 5 of the respirator module 102 is used for discharging the gas, and a part of the structure of the respirator module 102 can be formed into the gas discharging space 5, wherein, as shown in Figure 1 The gas discharging space 5 is provided with the gas inlet 51 for discharging the gas, and the gas discharging space 5 is also provided with the gas outlet 52 for communicating with the outside space, so that the gas entering the gas inlet 51 is discharged from the gas outlet 52 of the gas discharging space 5 to the outside of the respirator module 102.

[0046] Further, after the bubble generating device 100 is connected with some cleaning equipment, a large amount of gas-liquid mixture wrapped with the gas is generated by the bubble generating module 101 for cleaning the articles, and in the cleaning process, the gas with heat is generated in the cleaning space, and when the gas increases and the pressure increases, the gas in the cleaning equipment can enter the gas discharging space 5 from the gas inlet 51, and be discharged from the gas outlet 52 of the gas discharging space 5, so as to reduce the pressure in the cleaning process and improve the safety and stability of the article cleaning, and the structure is reasonable and reliable.

[0047] According to the bubble generating device 100 of the embodiment of the utility model, by setting the bubble generating module 101 and the respirator module 102 to be connected, the washing characteristics of the article can be improved, and the discharge of gas can be realized, in the existing respirator module 102, the respirator module 102 is connected with the water inlet tank, the water inlet tank only has the function of water supply, and the cleaning effect on the article is not good, but in the embodiment, the bubble generating module 101 and the respirator module 102 are integrated, the gas and the liquid can be dissolved in the process of water supply, the number of bubbles mixed in the liquid can be improved, and thus the article cleaning effect is improved. And the bubble generating module 101 occupies the original water inlet tank, does not increase the overall size of the bubble generating device 100, reduces the setting cost, and in the limited space, the bubble generating module 101 and the respirator module 102 are set, the structure is compact, the function is perfect, and the use effect is good.

[0048] In some embodiments, a drainage flow channel 6 is further formed in the respirator module 102, the drainage flow channel 6 is provided with a drainage inlet 61 and a drainage outlet 62, and the drainage inlet 61 and the drainage outlet 62 are respectively communicated with the external waterway.

[0049] Specifically, the drainage flow channel 6 is used for discharging liquid, and another part of the structure of the respirator module 102 can be formed into the drainage flow channel 6, wherein, as shown in Figure 1 and Figure 3 The drainage flow channel 6 is provided with a drainage inlet 61 communicated with the external waterway, the drainage inlet 61 is used for discharging liquid, and the drainage flow channel 6 is further provided with a drainage outlet 62, the drainage flow channel 6 can be communicated with the external waterway through the drainage outlet 62, so that when the washing is finished, the washed sewage enters the drainage flow channel 6 from the drainage inlet 61, and then is discharged to the outside of the respirator module 102 through the drainage pipe, so as to realize the discharge of the sewage. The drainage flow channel 6 can be used as the central pipeline of drainage, and the drainage flow channel 6 is further connected with a drainage pump for sucking liquid flow.

[0050] The drainage flow channel 6 is communicated with the exhaust space 5, so that the gas in the exhaust space 5 can enter the drainage flow channel 6, the gas pressure in the drainage flow channel 6 can be supplemented, the pressure of the drainage flow channel 6 can be balanced, and backflow of the drainage flow channel 6 can be avoided, and in this way, the circulation use of the gas in the exhaust space 5 can be realized, and the utilization rate of the gas is improved.

[0051] The drainage inlet 61 and the drainage outlet 62 can be arranged at the bottom of the respirator module 102 and spaced apart, so that a reverse U-shaped liquid flow path is formed, so that the overall structure of the channel is more compact, the occupied space is smaller, and the integration degree is improved.

[0052] In some embodiments, a connection channel 7 is further formed in the respirator module 102, the connection channel 7 having a connection inlet 71 and a connection outlet 72, the connection inlet 71 being in communication with the exhaust space 5, and the connection outlet 72 being in communication with the drainage flow channel 6.

[0053] Specifically, the connection channel 7 is located between the exhaust space 5 and the drainage flow channel 6, and the connection channel 7 is in communication with the exhaust space 5 through the connection inlet 71 and in communication with the drainage flow channel 6 through the connection outlet 72, wherein the connection channel 7 is located on the side of the exhaust space 5 away from the gas dissolving space 12, and the connection channel 7 can be arranged to extend vertically, so that the gas in the exhaust space 5 can be introduced into the drainage flow channel 6 through the connection channel 7.

[0054] Further, during the washing process and when the drainage flow channel 6 is draining, a negative pressure state can be formed inside the drainage flow channel 6, which can easily form a siphon effect, causing the liquid drained from the drainage flow channel 6 to backflow. In the present embodiment, the gas is quickly introduced into the drainage flow channel 6 through the connection channel 7, which can supplement the gas pressure in the drainage flow channel 6, thereby preventing the backflow of the water flow during the drainage process.

[0055] Wherein, the exhaust outlet 52 of the exhaust space 5 is in communication with the external space, that is, when the exhaust space 5 is not exhausting, or the pressure of the exhaust space 5 is lower than the external space, the external gas can enter the exhaust space 5 through the exhaust outlet 52, and the entering gas can flow to the connection channel 7, which can also achieve the gas supply to the connection channel 7.

[0056] Thus, by the above arrangement, the gas in the external space or the exhaust space 5 can enter the drainage flow channel 6, which can effectively supplement the gas pressure in the drainage flow channel 6 to balance the pressure of the drainage flow channel 6, thereby preventing siphon effect, and the structure is simple and the use effect is good.

[0057] Wherein, the connection channel 7 can be integrally formed with the respirator module 102, or a separate pipe can be provided and detachably connected with the respirator module 102.

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

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

[0060] Further, during the washing process, and when the drainage siphon effect is encountered, the second one-way valve 73 is opened by the larger air pressure from the outside, the gas enters the exhaust space 5 from the exhaust outlet 52, and enters the connecting channel 7 through the second one-way valve 73, so that the air pressure inside the drainage flow channel 6 is balanced, thereby playing a role in preventing siphon.

[0061] Therefore, by arranging the second one-way valve 73, the gas can flow unidirectionally, and the air pressure of the drainage flow channel 6 and the outside space is balanced, thereby improving the stability of liquid discharge.

[0062] In some embodiments, the drainage flow channel 6 and the exhaust space 5 are located on the same side of the gas dissolving space 12, as shown in Figure 1 and Figure 3 As shown, the drainage flow channel 6 and the exhaust space 5 are spaced apart in the up-down direction and are located on the same side of the gas dissolving space 12, so that the drainage flow channel 6 and the exhaust space 5 occupy one side of the bubble generating device 100, and the gas dissolving space 12 occupies the other side of the bubble generating device 100, so that the three can be integrated, and the occupied space of the gas dissolving space 12 is greater than that of the drainage flow channel 6 and the exhaust space 5, so that more space can be used for mixing of gas and liquid, thereby improving the gas-liquid mixture required in the washing process, and the bubble generating device 100 has gas-liquid mixing function, exhaust function and drainage function, which is reasonable in arrangement and compact in structure, and can improve the cleaning function of the article.

[0063] In other embodiments, the breather module 102 and the bubble generating module 101 are connected in the horizontal direction, that is, the breather module 102 and the bubble generating module 101 are sequentially arranged in the horizontal direction, and both are arranged in the horizontal direction, so that when the breather module 102 is connected with the bubble generating module 101 and the matching equipment, only the side space of the equipment can be occupied, so that the installation is more convenient and simple, and the structure is more compact, the occupied space is small, and the integration with other equipment is facilitated.

[0064] Among them, the bubble generating device 100 can be arranged in the left-right direction, or in the front-rear direction, or in an inclined direction, and the arrangement direction is related to the equipment to be matched, and the arrangement mode is various.

[0065] The drainage flow channel 6 is located below the exhaust space 5, which can make the drainage flow channel 6 discharge the liquid in the washing space 11 faster, and is beneficial to the discharge of the gas in the washing space 11 from the exhaust space 5, so as to realize the discharge of the gas from the upper side and the discharge of the liquid from the bottom, improve the exhaust efficiency and the drainage efficiency, and the two do not affect each other, thereby improving the working efficiency and stability of the washing equipment 100.

[0066] Therefore, the drainage flow channel 6 can occupy the lower side space of the respirator module 102, and the exhaust space 5 can occupy the upper side space of the respirator module 102, so as to realize the lower side drainage and the upper side exhaust, and make the liquid and the gas be discharged more smoothly. Through the arrangement in the up-down direction, the two occupy the upper and lower spaces of the respirator module 102, without expanding the horizontal size of the respirator module 102, and the overall structure is more compact.

[0067] It should be noted that the gas dissolving space 12 can be integrated with the drainage flow channel 6, which can provide bubble water for the equipment and realize the discharge of the liquid after washing. In addition, the gas dissolving space 12 can be integrated with the exhaust space 5, which can provide bubble water for the equipment and realize the discharge of the gas during the washing process. In addition, the three can be integrated, which can provide bubble water for the equipment and discharge the gas and liquid in the equipment. The setting mode is various, and can be selectively set.

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

[0069] Specifically, the connecting channel 7 is located between the exhaust space 5 and the drainage flow channel 6, and the connecting channel 7 communicates with the exhaust space 5 through the connecting inlet 71 and communicates with the drainage flow channel 6 through the connecting outlet 72. In addition, the connecting channel 7 is located on the side of the exhaust space 5 away from the gas dissolving space 12, and at least part of the structure of the connecting channel 7 can extend in the vertical direction, so that the gas in the exhaust space 5 can be introduced into the drainage flow channel 6 through the connecting channel 7 along the vertical path.

[0070] In addition, through such arrangement, the gas can be quickly supplemented into the drainage flow channel 6 to supplement the pressure in the drainage flow channel 6.

[0071] Further, during the washing process and when the drainage flow channel 6 discharges water, a negative pressure state will be formed in the drainage flow channel 6, which is easy to form a siphon effect and cause the backflow of the liquid discharged from the drainage flow channel 6. In the present embodiment, the gas is quickly introduced into the drainage flow channel 6 through the connecting channel 7, which can supplement the gas pressure in the drainage flow channel 6, thereby preventing the backflow of the water flow during the drainage process.

[0072] In some embodiments, the air inlet 13 is in communication with 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, as shown in Figure 1 and Figure 3 , the exhaust inlet 51 and the exhaust outlet 52 are spaced apart in the vertical direction, the exhaust inlet 51 can be arranged in the middle region of the respirator module 102, and the exhaust outlet 52 can be arranged in the top region of the respirator module 102, so that the exhaust inlet 51 is in communication with the upper region of the scrubbing chamber of the device, so that the gas in the scrubbing chamber enters the exhaust space 5 through the exhaust inlet 51, and is discharged from the exhaust outlet 52 in the exhaust space 5 from bottom to top to the outside of the respirator module 102, achieving gas exhaust.

[0074] Therefore, by arranging the exhaust inlet 51 in the middle region of the respirator module 102, the gas in the scrubbing chamber can be easily discharged, and the probability of liquid in the scrubbing chamber entering the exhaust space 5 can be reduced, thereby maintaining sufficient liquid in the scrubbing chamber, ensuring cleaning performance, and arranging the exhaust outlet 52 above the exhaust inlet 51, so that after the liquid in the scrubbing chamber enters the exhaust inlet 51, the liquid will not flow upward by its own gravity, thereby reducing the possibility of liquid discharge, which is reasonable in arrangement and smooth in gas discharge.

[0075] and the exhaust outlet 52 and the air inlet 13 are spaced apart in the horizontal direction, as shown in Figure 1 , the exhaust outlet 52 penetrates the respirator module 102 and is directly in communication with the external space, the air inlet 13 and the exhaust outlet 52 are spaced apart, and the air inlet 13 does not directly penetrate the respirator module 102, wherein external air can enter the exhaust space 5 through the exhaust outlet 52, and when the air inlet 13 is opened, the gas at the exhaust outlet 52 flows to the air inlet 13 and then flows into the air inlet channel 3, and 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, and the flow direction of the gas is not unique and can be selectively adjusted according to the working state of the device.

[0076] In addition, the exhaust outlet 52 and the air inlet 13 are spaced apart in the horizontal direction, and during the exhaust process, the exhaust is smooth through the exhaust outlet 52 and is not affected by the resistance of the air inlet, and only one connection hole is provided with the external space, so that the overall structure is simpler and more convenient to use.

[0077] and the air inlet 13 is in communication with the exhaust space 5, so that the gas in the exhaust space 5 enters the gas dissolving space 12 or the air inlet channel 3 through the air inlet 13, providing gas for the Venturi pipe 2, realizing the recycling use of the gas in the exhaust space 5, and improving the utilization rate of the gas.

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

[0079] Specifically, the exhaust space 5 is provided with a plurality of turbulence ribs 53 for blocking the gas in the exhaust space 5, and the plurality of turbulence ribs 53 are distributed between the exhaust inlet 51 and the exhaust outlet 52, and the extending direction of the turbulence ribs 53 intersects with the arrangement direction of the exhaust inlet 51 and the exhaust outlet 52, wherein the exhaust inlet 51 and the exhaust outlet 52 are arranged along the up-down direction, and the extending direction of the turbulence ribs 53 can be along the horizontal direction, that is, the extending direction of the turbulence ribs 53 is perpendicular to the up-down direction, or the extending direction of the turbulence ribs 53 is non-perpendicular to the up-down direction, and the setting mode is various and optional.

[0080] As shown in Figure 2 and Figure 3 , the turbulence ribs 53 located in the middle region of the exhaust space 5 are configured as arc-shaped structures, and the turbulence ribs 53 located on both sides of the exhaust space 5 are configured as linear structures, wherein the two ends of the arc-shaped turbulence ribs 53 are open towards one end of the exhaust inlet 51, and the linear turbulence ribs 53 extend towards the arc-shaped turbulence ribs 53, so that the gas flowing from bottom to top at the exhaust inlet 51 can be blocked by the plurality of turbulence ribs 53 multiple times, and the gas can flow along a certain path, and the flow path of the gas can be increased.

[0081] Therefore, by providing a plurality of turbulence ribs 53, the gas flow path length and resistance in the exhaust space 5 can be increased, so that the gas flowing through the turbulence ribs 53 forms water droplets, thereby increasing the condensation speed of water vapor and reducing the discharge of condensed water. The plurality of turbulence ribs 53 are supported and connected in the exhaust space 5, which can improve the structural strength of the exhaust space 5.

[0082] In some embodiments, the bubble generating device 100 further comprises a Venturi tube 2, and the Venturi tube 2 is provided with an air inlet hole 21, a liquid inlet hole 22 and a mixed outlet hole 23, the air inlet hole 21 is in communication with the air inlet 13, the liquid inlet hole 22 is in communication with the liquid inlet 14, and the mixed outlet hole 23 is in communication with the gas dissolving space 12.

[0083] Specifically, as shown in Figure 1As shown, the air inlet hole 21 can be arranged at the inlet area of the Venturi pipe 2, and the air inlet hole 21 is communicated with the air inlet 13, so that the external space is communicated with the Venturi pipe 2 to realize the circulation of the gas. The liquid inlet hole 22 can be arranged at the inlet area of the Venturi pipe 2, and the liquid inlet hole 22 is communicated with the liquid inlet 14, so that the liquid inlet 14 is communicated with the Venturi pipe 2 to realize the circulation of the liquid. The mixed outlet hole 23 can be arranged at the outlet area of the Venturi pipe 2, and the mixed outlet hole 23 is communicated with the gas dissolving space 12, so that the Venturi pipe 2 is communicated with the gas dissolving space 12.

[0084] Further, the gas from the air inlet 13 enters the gas dissolving space 12, and the gas from the air inlet hole 21 enters the Venturi pipe 2. At the same time, the liquid at the liquid inlet 14 enters the Venturi pipe 2 from the liquid inlet hole 22, and the gas and the liquid are mixed in the Venturi pipe 2, and then enter the gas dissolving space 12 from the mixed outlet hole 23, and the mixing of the gas and the liquid continues in the gas dissolving space 12.

[0085] It should be noted that the inside of the Venturi pipe 2 is provided with a Venturi structure, and the cross section of the Venturi structure gradually decreases and then gradually increases from the inlet area to the outlet area of the Venturi pipe 2. When the liquid passes through the narrow channel, a vacuum area is formed in the Venturi pipe 2, and the water flow can suck the gas in the Venturi pipe 2 to mix the liquid and the gas for the first time. The mixed gas and liquid enter the gas dissolving space 12 to be mixed for the second time, so that the mixing characteristics of the liquid and the gas are improved.

[0086] The Venturi pipe 2 can be integrally formed with the bubble generating device 100, or a separate pipe can be arranged and detachably connected with the bubble generating device 100.

[0087] In some embodiments, the air inlet channel 3 is further formed in the bubble generating module 101, and the air inlet channel 3 is communicated between the air inlet hole 21 and the air inlet 13.

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

[0089] In this way, external air can be directly introduced into the venturi pipe 2 through the air inlet channel 3, or the gas in the dissolved gas space 12 can be introduced into the venturi pipe 2, thereby improving the gas supply mode of the venturi pipe 2, and recycling the remaining gas in the dissolved gas space 12, thereby improving the air utilization rate of the overall system, and improving the mixing of gas and liquid.

[0090] The air inlet channel 3 can be integrally formed with the bubble generating module 101, or a separate pipe can be provided and detachably connected to the bubble generating module 101.

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

[0092] Specifically, the liquid inlet channel 4 is arranged 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, the liquid at the liquid inlet 14 can be introduced into the liquid inlet hole 22 through the liquid inlet channel 4, thereby 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 can be connected to a water tank provided in the bubble generating module 101, and the liquid inlet channel 4, the venturi pipe 2 and the dissolved gas space 12 are connected in sequence along the flow direction of the liquid. 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 mixed in the venturi pipe 2 and the dissolved gas space 12, and then the mixed gas-liquid mixture is introduced into the washing cavity of the device.

[0093] Therefore, through the above arrangement, the mixing of gas and liquid can be realized during water supply to the washing cavity of the device, and the liquid wrapped with gas can be provided to the washing cavity, thereby improving the cleaning characteristics of the washing articles.

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

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

[0096] Specifically, the top of the air inlet channel 3 communicates with the top of the gas dissolving space 12, and at least part of the air inlet channel 3 extends downward, wherein the air inlet channel 3 is provided with an arc-shaped channel at both the top region of the gas dissolving space 12 and the connection between the air inlet channel 3 and the Venturi pipe 2, so that the air inlet channel 3 is distributed outside the first gas dissolving region 123 of the gas dissolving space 12, and the air inlet channel 3 is arranged horizontally side by side with the first gas dissolving region 123. The gas not involved in the fusion at the top of the gas dissolving space 12 can be introduced into the Venturi pipe 2 through the air inlet channel 3 downward, realizing the recycling of the gas, and the air inlet channel 3 occupies less space, and the overall structure is compact and has higher integration.

[0097] In addition, the air inlet channel 3 is arranged horizontally side by side with the first gas dissolving region 123, and the air inlet channel 3 is a separate channel. The gas at the top of the first gas dissolving region 123 and the gas from the external space can be introduced into the Venturi pipe 2 through the air inlet channel 3, which can improve the air inlet amount of the Venturi pipe 2.

[0098] In some embodiments, the liquid inlet channel 4 communicates with the lower part of the Venturi pipe 2, for example, the liquid inlet channel 4 can be detachably connected with the Venturi pipe 2, for example, as shown in Figure 1 and Figure 3 The Venturi pipe 2 extends in the vertical direction, and the lower end thereof communicates with the liquid inlet channel 4, so that the liquid can flow into the Venturi pipe 2 from the lower part to the upper part along the liquid inlet channel 4. In addition, the liquid inlet channel 4 is arranged to store a certain amount of liquid during the washing process, so that the mixing of the liquid and the gas in the Venturi pipe 2 is stably carried out. A water pump can be arranged in the liquid inlet channel 4 to realize the delivery of the liquid.

[0099] In addition, the liquid inlet channel 4 is arranged at the lower part of the Venturi pipe 2, so that the two are distributed in the vertical direction, which can occupy the vertical space of the bubble generating module 101, so that the overall structure is more compact and reasonable, and the utilization rate of the internal space of the bubble generating module 101 is effectively improved.

[0100] In other embodiments, the gas dissolving space 12 communicates with the upper end of the Venturi pipe 2, for example, as shown in Figure 1 and Figure 3 The gas dissolving space 12 is distributed in the vertical direction, and the upper region of the gas dissolving space 12 communicates with the upper end of the Venturi pipe 2, so that the gas and liquid mixture in the Venturi pipe 2 enters the upper region of the gas dissolving space 12, and the mixing of the gas and the liquid is continuously carried out in the gas dissolving space 12, and the gas and liquid mixture flows downward in the vertical direction, which can improve the flow rate of the gas and liquid mixture, thereby improving the speed of delivering the liquid to the washing space 11, and improving the cleaning efficiency and the cleaning quality of the articles.

[0101] And the gas dissolving space 12 is communicated with the upper end of the Venturi pipe 2, so that the gas-liquid mixture in the gas dissolving space 12 can increase the flow rate by gravity, and the flow direction of the liquid is upward first and then downward, which can utilize the vertical space on the same side of the bubble generating module 101, so that the overall structure is more compact and reasonable.

[0102] In other embodiments, the air inlet channel 3 is communicated with the peripheral wall of the Venturi pipe 2, as shown in Figure 1 and Figure 3 The air inlet channel 3 can extend vertically, and the outlet end of the air inlet channel 3 extends to the air inlet hole 21 of the inlet area of the outer periphery of the Venturi pipe 2, and the inlet end of the air inlet channel 3 is communicated with the top of the gas dissolving space 12, so that the gas that has not been dissolved in the gas dissolving space 12 can flow from the top of the gas dissolving space 12 into the air inlet channel 3 and then into the Venturi pipe 2, realizing the recycling of the gas.

[0103] And the liquid inlet channel 4 is communicated with the liquid inlet hole 22 at the bottom of the Venturi pipe 2, which is arranged separately from the air inlet channel 3 to realize peripheral air inlet and bottom water inlet, respectively. This arrangement separates the air inlet and water inlet structures and does not affect each other.

[0104] In this embodiment, the air inlet channel 3 is arranged on the right side of the Venturi pipe 2, and the gas dissolving space 12 is arranged on the left side of the Venturi pipe 2, so that they are separated from each other to realize different functions and are arranged reasonably without interference.

[0105] In some embodiments, the liquid inlet channel 4 is provided with a flow meter 8, which is used to measure the flow of the liquid in this embodiment. The flow meter 8 can measure the flow of the fluid in the pipe according to the physical law of the fluid and the form of fluid motion, which is convenient for understanding the real-time flow of the liquid.

[0106] The flow meter 8 is detachably connected to the liquid inlet channel 4. After the liquid inlet channel 4 is filled with liquid during use, the water inlet amount of the liquid inlet channel 4 can be detected through the flow meter 8. The flow meter 8 can accurately measure the flow of the fluid and provide accurate flow data to ensure that the water inlet amount meets the design requirements. The liquid flow of the liquid inlet channel 4 can be monitored in real time, and the flow can be adjusted and controlled as needed, which helps to ensure the uniformity and stability of the liquid and gas mixing process.

[0107] In some embodiments, the air inlet channel 3 is located above the liquid inlet channel 4, as shown in Figure 1 The air inlet channel 3 and the liquid inlet channel 4 are spaced apart and connected to the Venturi pipe 2, so that water inlet and air inlet can be realized respectively.

[0108] Therefore, by arranging the air inlet channel 3 above the liquid inlet channel 4, the gas in the gas dissolving space 12 can enter the air inlet channel 3 from the top, which is conducive to introducing the gas into the Venturi tube 2, and arranging the liquid inlet channel 4 below can make the liquid flow into the Venturi tube 2 from bottom to top, so that the liquid in the Venturi tube 2 mixes with the gas in the gas dissolving space 12 after flowing into the gas dissolving space 12, and the gas not involved in the mixing process can be squeezed to flow upward, and the gas not involved in the mixing process can be squeezed into the air inlet channel 3, so that the gas can flow into the Venturi tube 2 for further mixing with the liquid. The arrangement is more reasonable and simple, the circulation flow speed of the gas is improved, and the utilization rate of the gas is improved.

[0109] Further, the liquid inlet channel 4 is arranged below the Venturi tube 2, and the air inlet channel 3 and the liquid inlet channel 4 are arranged in a spaced manner, so that the liquid can flow into the Venturi tube 2 from bottom to top along the liquid inlet channel 4, and the gas can flow into the Venturi tube 2 from top to bottom along the air inlet channel 3, so as to realize the mixing of the gas and the liquid in the Venturi tube 2, and the inlet paths of the gas and the liquid are spaced apart to realize peripheral air inlet and bottom water inlet, respectively, and the air inlet channel 3 can make the gas not involved in the mixing in the gas dissolving space 12 flow into the air inlet channel 3 from the top of the gas dissolving space 12 and then into the Venturi tube 2, so as to realize the recycling of the gas. Therefore, by the above arrangement, the air inlet and the water inlet are separated, and they do not affect each other.

[0110] In some embodiments, the gas dissolving space 12 is provided with a first one-way valve 31, the first one-way valve 31 is arranged to be one-way conductive from the air inlet 13 to the gas dissolving space 12, and the first one-way valve 31 is configured to be opened under the action of negative pressure at the air inlet hole 21.

[0111] Specifically, the first one-way valve 31 is used for one-way conduction of the gas, as shown in Figure 2 The first one-way valve 31 is arranged at the top of the gas dissolving space 12 and located at the inlet end of the air inlet channel 3, the first one-way valve 31 is detachably connected to the top of the gas dissolving space 12 and close to the air inlet 13, and when the inside of the air inlet channel 3 is in a negative pressure state, a pressure difference is formed between the gas dissolving space 12 and the outside space, so that the first one-way valve 31 is opened by the pressure difference, so that the gas is one-way conductive from the air inlet 13 to the air inlet hole 21.

[0112] Further, when water is added, the first one-way valve 31 is in a closed state, and the gas dissolving space 12 forms a sealed space. After the water addition is completed, the water in the gas dissolving space 12 flows downward by gravity, so that the pressure in the gas dissolving space 12 is less than the external pressure, the first one-way valve 31 is opened by the air pressure difference, and the external gas enters the gas dissolving space 12 and the air inlet channel 3 from the air inlet 13 through the first one-way valve 31, thereby realizing the air supply to the Venturi tube 2, and the next step of mixing the gas and the liquid can be realized.

[0113] When the liquid inlet channel 4 is filled with water, and when a negative pressure state is formed inside the air dissolving space 12, a siphon effect is easily formed. At this time, the first one-way valve 31 is opened by the greater air pressure from the outside, and air flows into the air dissolving space 12 to balance the pressure difference, thereby playing a role in preventing siphon.

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

[0115] In some embodiments, the liquid inlet 14 and the liquid outlet 15 are arranged 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 to the liquid inlet channel 4, the Venturi channel 2 and the air dissolving space 12 in sequence, and the gas-liquid mixture in the air dissolving space 12 flows downward to the bottom of the bubble generating module 101, forming a reverse U-shaped flow path. In this way, the distribution of multiple channels can be more compact, and the space occupied can be smaller, thereby improving the overall integration.

[0116] The liquid inlet 14 and the liquid outlet 15 are located at the bottom of the air dissolving space 12, and the liquid inlet channel 4 is arranged to extend upward from the liquid inlet 14 to communicate with the air dissolving space 12. In this way, the liquid can flow upward from the liquid inlet 14 at the bottom to the air dissolving space 12 through the liquid inlet channel 4, and then mix with the gas in the air dissolving space 12. The mixed liquid and gas in the air dissolving space 12 flow toward the liquid outlet 15 at the bottom. The liquid inlet 14 and the liquid outlet 15 are arranged at a lower position, so that the liquid first rises for a distance and then flows downward. This facilitates the flow of the liquid and the gas in the air dissolving space 12 relying on their own gravity, so that the kinetic energy of the liquid flowing downward is greater, thereby improving the flow speed of the liquid.

[0117] The liquid outlet 15 is arranged at the bottom of the bubble generating module 101, which can utilize the gravity of the liquid to improve its flow speed and improve the cleaning speed of the object. The liquid containing bubbles can enter the washing cavity from the bottom of the bubble generating module 101, thereby 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 air dissolving space 12 is provided with a flow disturbing structure 121, which is arranged to guide the mixed liquid first in a direction away from the liquid outlet 15 and then toward the liquid outlet 15.

[0119] That is, the mixed liquid after dissolution can be guided by the flow disturbance structure 121 in a direction away from the liquid outlet 15, and then guided by the flow disturbance structure 121 in a direction close to the liquid outlet 15 when the distance between the mixed liquid and the liquid outlet 15 is larger, so that the flow direction of the mixed liquid is in a reverse U shape. In this way, the mixed liquid can flow along the U-shaped path in the gas dissolving space 12 by the flow disturbance structure 121, the distance of the mixed liquid to the liquid outlet 15 is larger, the kinetic energy of the mixed liquid is larger, and the flow speed of the mixed liquid is faster. Compared with directly guiding the mixed liquid in the direction of the liquid outlet 15, the flow path of the mixed liquid is increased, so that the mixed liquid can flow from the liquid outlet 15 after sufficient fusion in the gas dissolving space 12, which improves the bubble generation amount of the bubble generation module 101 and improves the cleaning characteristics of the article.

[0120] The flow disturbance structure 121 provided in the gas dissolving space 12 can disturb the flow of the liquid and the gas entering the gas dissolving space 12, so as to change the flow direction of the gas and the liquid, so that the gas and the liquid are fully mixed in the gas dissolving space 12, and the gas-liquid mixture formed is flowed out from the liquid outlet 15 to realize the pre-mixing of the gas and the liquid. The flow disturbance structure 121 is arranged in the limited space of the gas dissolving space 12, which is beneficial to improve the mixing of the gas and the liquid under the impact and reflection of the flow disturbance structure 121, improve the cleaning quality, and has simple structure and easy-to-implement function.

[0121] In some embodiments, the flow disturbance structure 121 includes first flow disturbance ribs 1211 and second flow disturbance ribs 1212, and the first flow disturbance ribs 1211 and the second flow disturbance ribs 1212 define flow disturbance channels 1213 therebetween.

[0122] Specifically, the first flow disturbance ribs 1211 and the second flow disturbance ribs 1212 can each be provided as at least one, wherein the first flow disturbance ribs 1211 and the second flow disturbance ribs 1212 are cross-distributed, that is, the first flow disturbance ribs 1211 and the second flow disturbance ribs 1212 are cross-connected, and the two can be connected vertically or non-vertically, and the flow disturbance channels 1213 are defined between the at least one first flow disturbance rib 1211 and the at least one second flow disturbance rib 1212. The gas and the liquid can flow along the flow disturbance channels 1213, and after at least one reflection and impact of the at least one first flow disturbance rib 1211 and the at least one second flow disturbance rib 1212, the gas and the liquid are fully mixed, thereby improving the ability of the gas-liquid mixture to clean stains, that is, improving the cleaning effect. The flow disturbance channels 1213 are connected between the mixing inlet 122 and the liquid outlet 15, so that the mixed gas-liquid mixture flows to the liquid outlet 15 through the flow disturbance channels 1213.

[0123] The first flow disturbance ribs 1211 and the second flow disturbance ribs 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 turbulence rib 1211 and the second turbulence rib 1212 can be one, two, three, four, etc., and the number of the first turbulence rib 1211 and the second turbulence rib 1212 can be the same or different, which is not limited in the embodiment and can be selected according to the actual space size.

[0130] In some embodiments, the at least one first turbulence rib 1211 extends in the horizontal direction and the vertical direction, and the first turbulence rib 1211 surrounds the mixing inlet 122 to separate the mixing inlet 122 from the air inlet 13. In this way, an L-shaped turbulence flow channel 1213 can be formed, so that the gas and the liquid can flow in the horizontal direction and the vertical direction under the flow guiding action of the first turbulence rib 1211 to change the flow direction of the liquid and the gas. The second turbulence rib 1212 can extend in the horizontal direction to form different turbulence flow sections 1214 extending in the vertical direction and the horizontal direction, respectively, that is, a curved turbulence flow channel 1213 can be formed to prolong the length of the turbulence flow channel 1213. The structure is simple, easy to process, and easy to function.

[0131] The shape of 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 the liquid entering the gas dissolving space 12 can avoid directly impacting the air inlet 13, causing the air inlet 13 to fail to seal, thereby improving the sealing properties of the air inlet 13 and the reliability and stability of the water inlet process.

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

[0133] In this way, the liquid can flow upward from the bottom liquid inlet 14 to the gas dissolving space 12 through the liquid inlet channel 4, and mix with the gas in the gas dissolving space 12. The mixed liquid and gas in the gas dissolving space 12 flow toward the bottom liquid outlet 15. The liquid inlet 14 and the liquid outlet 15 are arranged at a lower position, so that the liquid first rises for a distance and then flows downward, which facilitates the flow of the liquid and the gas in the gas dissolving space 12 relying on their own gravity, so that the liquid has greater kinetic energy when flowing downward, thereby improving the flow speed of the liquid.

[0134] Specifically, the liquid inlet 14 and the liquid outlet 15 are spaced apart at the bottom of the gas dissolving space 12, the liquid inlet channel 4 is located between the liquid inlet 14 and the gas dissolving space 12, and the liquid inlet channel 4 extends upward and is arranged away from the liquid inlet 14. One end of the liquid inlet channel 4 communicates with the gas dissolving space 12 to realize the communication between the liquid inlet channel 4 and the gas dissolving space 12.

[0135] Further, when the bubble generating device 100 is working, the air inlet 13 is in a closed state, at this time, due to the strong pressure of the liquid, more gas cannot be injected, so it is necessary to make full use of the existing gas in the dissolved gas space 12, after the liquid inlet 14 is opened, the liquid flows into the liquid inlet channel 4 and the dissolved gas space 12, the gas in the dissolved gas space 12 will flow out with the liquid, which will cause the gas content in the dissolved gas space 12 to decrease, and further cause the final generated bubble effect to decrease significantly. By setting the liquid outlet 15 at the bottom of the dissolved gas space 12, during the initial water inlet process in the dissolved gas space 12, the liquid in the dissolved gas space 12 is less, and the liquid will flow quickly from top to bottom to the liquid outlet 15 by gravity, and a water seal is formed above the liquid outlet 15, which can reduce the possibility of gas discharge in the dissolved gas space 12, and as the liquid is continuously transported, the remaining liquid mixes with the gas in the dissolved gas space 12, and the mixed gas and liquid flow out of the liquid outlet 15.

[0136] According to the bubble generating device 100 of the embodiment of the utility model, by setting the dissolved gas space 12 in the bubble generating module 1, the liquid before entering the bubble generator 9 is mixed with the gas in the dissolved gas space 12, and the liquid outlet 15 and the liquid inlet 14 are arranged at the bottom of the dissolved gas space 12, and the liquid inlet channel 4 is arranged to extend upwardly to communicate with the dissolved gas space 12 relative to the liquid inlet 14, which can make the liquid flow upwardly to the dissolved gas space 12 and flow out from the bottom of the liquid outlet 15, and quickly form a water seal in the liquid outlet 15, which can lock more gas in the dissolved gas space 12, and facilitate the liquid in the dissolved gas space 12 to mix with the gas sufficiently, and form a large amount of liquid containing bubbles, so that the washing characteristics of the article can be improved, and the use experience of the user can be improved.

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