[0032] As Figures 1-2 The bubble generating device 100 according to one embodiment of the utility model comprises a bubble generating module 101.

[0033] The bubble generating module 101 is provided with an air inlet 13, a liquid inlet 14 and a liquid outlet 15 which respectively communicate with the gas dissolving space 12, and the liquid entering the liquid inlet 14 and the gas entering the air inlet 13 are suitable for being mixed in the gas dissolving space 12 and then flowing to the liquid outlet 15.

[0034] Specifically, a part of the bubble generating module 101 can be formed as the gas dissolving space 12, the gas dissolving space 12 is used for mixing 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 further provided with the air inlet 13 which is used for communicating with the external space to introduce the gas, and the liquid inlet 14, the air inlet 13 and the liquid outlet 15 respectively communicate with the gas dissolving space 12, so that 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, and the gas-liquid mixture formed is discharged from the liquid outlet 15 to realize the pre-mixing of the gas and the liquid. The air inlet 13 is arranged 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 and improve the gas-liquid mixing efficiency.

[0035] The gas-liquid mixture pre-mixed in the gas dissolving space 12 can be used for washing the article, and the more bubbles formed after the solvus of the gas and the liquid in the gas dissolving space 12, the better the cleaning effect of the article.

[0036] The outlet 15 is communicated with the bubbler 9, wherein the bubbler 9 is used for mixing water and air to generate bubbles for effective cleaning of the articles to be cleaned. The outlet 15 is communicated with the bubbler 9, so that the dissolved gas space 12 is communicated with the bubbler 9. In this way, the gas-liquid mixture pre-mixed in the dissolved gas space 12 can be introduced into the bubbler 9 through the outlet 15, and further separated into liquid wrapped with ultra-micro bubbles in the bubbler 9. The liquid with ultra-micro bubbles can be used for washing the articles. The bubbler 9 is detachably connected with the outlet 15, so as to facilitate the installation and dismounting of the bubbler 9 and the bubble generating module 101.

[0037] The dissolved gas space 12 is provided with a turbulence structure 121, which is configured to guide the mixed liquid after dissolution first in a direction away from the outlet 15 and then in a direction towards the outlet 15.

[0038] That is, the turbulence structure 121 can guide the mixed liquid after dissolution first in a direction away from the outlet 15, and then guide the mixed liquid in a direction towards the outlet 15 when the distance between the mixed liquid and the outlet 15 is larger, so that the flow direction of the mixed liquid is in a reverse U shape. In this way, the turbulence structure 121 can make the mixed liquid flow along a U-shaped path in the dissolved gas space 12, so that the distance between the mixed liquid and the 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 a direction towards the outlet 15, the flow path of the mixed liquid is increased, so that the mixed liquid can flow from the outlet 15 to the bubbler 9 after sufficient mixing in the dissolved gas space 12, which improves the bubble generation amount of the bubble generating module 101 and is beneficial to improve the cleaning performance of the articles.

[0039] The turbulence structure 121 provided in the dissolved gas space 12 can disturb the liquid and gas entering the dissolved gas space 12, so as to change the flow direction of the liquid and gas, so that the liquid and gas are sufficiently mixed in the dissolved gas space 12, and the formed gas-liquid mixture flows out of the outlet 15 to realize the pre-mixing of the liquid and gas. The turbulence structure 121 is arranged in the limited space of the dissolved gas space 12, which is beneficial to improve the mixing of the liquid and gas under the impact and reflection of the turbulence structure 121, and can improve the cleaning quality, and the structure is simple and the function is easy to realize.

[0040] According to the bubble generating device 100, the gas and the liquid can be dissolved in the bubble generating module 101, the washing function of the device is realized, the mixed liquid after the dissolution can be first guided away from the liquid outlet 15 and then guided towards the liquid outlet 15 by the flow disturbing structure 121, the flow direction of the mixed liquid is in a reverse U shape, 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 towards the liquid outlet 15, the flow path of the mixed liquid is increased, the mixed liquid can flow from the liquid outlet 15 to the bubble generator 9 after being fully mixed in the gas dissolving space 12, the bubble generating amount of the bubble generating module 101 is larger, the cleaning performance of the article is improved, the use experience of the user is improved, the flow disturbing structure 121 is arranged, the space occupied by the mixed path of the gas and the liquid is reduced, and the overall structure is simple and low in cost.

[0041] In some embodiments, the bubble generating module 101 is further provided with a mixing inlet 122, the liquid entering the liquid inlet 14 and the gas entering the gas inlet 13 are adapted to enter the gas dissolving space 12 from the mixing inlet 122, and the extension direction of at least part of the flow disturbing structure 121 intersects the arrangement direction of the mixing inlet 122 and the liquid outlet 15.

[0042] Specifically, the mixing inlet 122 is located at the inlet area of the gas dissolving space 12, wherein, as shown in Figure 1 the mixing inlet 122 is located at the top of the gas dissolving space 12, and the mixing inlet 122 can be communicated with the liquid inlet 14 and the gas inlet 13 through different pipelines, and the liquid and the gas can be introduced into the gas dissolving space 12. At least part of the flow disturbing structure 121 in the gas dissolving space 12 extends in a direction intersecting the arrangement direction of the mixing inlet 122 and the liquid outlet 15, wherein the mixing inlet 122 is arranged at the middle position of the gas dissolving space 12, the liquid outlet 15 is arranged at the lower end of the gas dissolving space 12, and the arrangement direction of the two is the extension direction of the gas dissolving space 12. In actual design, at least part of the flow disturbing structure 121 in the gas dissolving space 12 can be arranged in a vertical direction intersecting the arrangement direction of the mixing inlet 122 and the liquid outlet 15, or can be arranged in a non-vertical direction, and the arrangement mode is various and can be selected.

[0043] Further, the liquid flows from the liquid inlet 14 to the mixing inlet 122, and the gas flows from the gas inlet 13 to the mixing inlet 122, both of which enter the gas dissolving space 12 from the mixing inlet 122, and are reflected and impacted by the flow disturbing structure 121, so that the gas and the liquid flow along the set path.

[0044] Therefore, by the above arrangement, the gas and liquid passing through the mixing inlet 122 can flow along the extension direction of the turbulence structure 121, the direct impact of the liquid on the gas dissolving space 12 is reduced, and the flow direction of the liquid and gas is more stable.

[0045] In some embodiments, the turbulence structure 121 includes first turbulence ribs 1211 and second turbulence ribs 1212, and a turbulence flow channel 1213 is defined between the first turbulence ribs 1211 and the second turbulence ribs 1212.

[0046] Specifically, the first turbulence ribs 1211 and the second turbulence ribs 1212 can each be arranged as at least one, wherein the first turbulence ribs 1211 and the second turbulence ribs 1212 are cross-distributed, that is, the first turbulence ribs 1211 and the second turbulence ribs 1212 are cross-connected, and the two can be connected vertically or non-vertically, and a turbulence flow channel 1213 is defined between at least one first turbulence rib 1211 and at least one second turbulence rib 1212, so that the gas and liquid can flow along the turbulence flow channel 1213, and the gas and liquid are fully mixed through at least one reflection and impact of at least one first turbulence rib 1211 and at least one second turbulence rib 1212, thereby improving the ability of the gas-liquid mixture to clean stains, that is, the cleaning effect can be improved. The turbulence flow channel 1213 is connected between the mixing inlet 122 and the liquid outlet 15, so that the mixed gas-liquid mixture can flow to the liquid outlet 15 through the turbulence flow channel 1213.

[0047] And the first turbulence ribs 1211 and the second turbulence ribs 1212 can also be distributed at intervals.

[0048] In some embodiments, the turbulence flow channel 1213 includes a plurality of turbulence flow sections 1214, and the extension directions of at least two turbulence flow sections 1214 in the plurality of turbulence flow sections 1214 intersect.

[0049] Specifically, the first turbulence ribs 1211 and the second turbulence ribs 1212 form a turbulence flow channel 1213, the turbulence flow channel 1213 includes a plurality of turbulence flow sections 1214, and the plurality of turbulence flow sections 1214 are connected in sequence, wherein at least two turbulence flow sections 1214 extend in different directions, and the at least two turbulence flow sections 1214 can be distributed vertically or non-vertically, so that the flow direction of the gas and liquid can be changed, that is, the gas and liquid flow in different directions in the plurality of turbulence flow sections 1214, the flow path length is increased, and the gas and liquid are impacted to be fully mixed.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] In some embodiments, the at least one first turbulence rib 1211 is bent to extend along the horizontal direction and the vertical direction, and surrounds the mixing inlet 122 to separate the mixing inlet 122 from the air inlet 13, so that an L-shaped turbulence flow channel 1213 is formed, so that the gas and the liquid can flow along the horizontal direction and the vertical direction under the flow guiding effect of the first turbulence rib 1211 to change the flow direction of the liquid and the gas, and the second turbulence rib 1212 can extend along the horizontal direction to form different turbulence flow sections 1214 extending along the vertical direction and the horizontal direction, that is, a curved turbulence flow channel 1213 is formed, which can prolong the length of the turbulence flow channel 1213. The structure is simple, easy to process, and easy to function.

[0055] The shape of the first turbulence rib 1211 is configured as an L shape, so that the first turbulence rib 1211 surrounds the mixing inlet 122 and separates the mixing inlet 122 from the air inlet 13, so that the gas and the liquid entering the gas dissolving space 12 can not directly impact the air inlet 13, causing the air inlet 13 to fail to seal, thereby improving the sealing properties of the air inlet 13 and improving the reliability and stability of the water inlet process.

[0056] In some embodiments, the liquid in at least one turbulence flow section 1214 is arranged to flow away from the liquid outlet 15, and the liquid in at least another turbulence flow section 1214 is arranged to flow towards the liquid outlet 15, so that the flow direction of the gas and the liquid in the turbulence flow section 1214 can be changed, so that part of the liquid and the gas will not directly flow to the liquid outlet 15, so that the liquid and the gas can fill the gas dissolving space 12, thereby improving the mixing sufficiency of the liquid and the gas.

[0057] In some embodiments, the first turbulence rib 1211 and the second turbulence rib 1212 are respectively a plurality of first turbulence ribs 1211 and a plurality of second turbulence ribs 1212, and the at least one first turbulence rib 1211 and the at least one second turbulence rib 1212 are spaced apart and distributed, wherein the plurality of first turbulence ribs 1211 are spaced apart and distributed along the extension direction of the first turbulence rib 1211, and the plurality of second turbulence ribs 1212 are also arranged to be spaced apart and distributed along the extension direction of the first turbulence rib 1211.

[0058] In this way, the liquid in at least one turbulence flow section 1214 can flow towards the liquid outlet 15, that is, part of the liquid can directly flow out of the liquid outlet 15 along the turbulence flow section 1214, and the liquid in at least another turbulence flow section 1214 can flow away from the liquid outlet 15, that is, part of the liquid can fill the space of the gas dissolving space 12 away from the liquid outlet 15.

[0059] Thus, by setting the liquid to flow in opposite directions within the dissolved gas space 12, the gas that does not participate in the fusion can be squeezed to the top of the dissolved gas space 12 while the liquid fills the dissolved gas space 12 more, and the gas at the top can continue to flow to the mixing inlet 122 to continue to participate in the subsequent mixing of liquid and gas.

[0060] In some embodiments, the mixing inlet 122 is higher than the liquid outlet 15, and the liquid at the mixing inlet 122 is suitable to be guided upward by the turbulence structure 121 above the mixing inlet 122 and downward below the mixing inlet 122 and then flow out through the liquid outlet 15.

[0061] Specifically, the mixing inlet 122 is set to be higher than the liquid outlet 15, i.e., the mixing inlet 122 and the liquid outlet 15 are spaced apart in the up-down direction and distributed at both ends of the dissolved gas space 12, so that the liquid and gas entering the mixing inlet 122 can flow from top to bottom in the dissolved gas space 12, wherein the turbulence structure 121 near the mixing inlet 122 in the dissolved gas space 12 is set to extend upward first, extend horizontally, and then extend downward, which can form an L-shaped turbulence flow channel 1213, so that the gas and liquid entering the mixing inlet 122 are guided upward by the turbulence structure 121 to the upper part of the mixing inlet 122 and downward to the lower part of the mixing inlet 122 and then flow out from the bubble generating module 101 through the liquid outlet 15, i.e., the liquid and gas flow forms an inverted U-shaped flow at the top of the dissolved gas space 12, which can avoid the gas and liquid entering the dissolved gas space 12 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 improving the reliability and stability of the water inlet process.

[0062] In some embodiments, the liquid outlet 15 is arranged at the lower end of the dissolved gas space 12, and the opening direction of the mixing inlet 122 and the opening direction of the liquid outlet 15 are opposite in the up-down direction. In the up-down direction, the mixing inlet 122 is located at the middle position of the dissolved gas space 12, and the opening direction of the mixing inlet 122 is open toward the top of the dissolved gas space 12, and the liquid outlet 15 is located at the bottom of the dissolved gas space 12, and the opening direction of the liquid outlet 15 is open toward the lower end, so that the liquid and gas at the mixing inlet 122 can flow toward the top of the dissolved gas space 12, and after the gas and liquid dissolve in the dissolved gas space 12, they can flow out toward the bottom of the liquid outlet 15 and then flow out from the lower end of the liquid outlet 15 to the bubbler 9, which can make the gas and liquid rise for a distance and then flow downward, thereby improving the kinetic energy of the gas and liquid to increase the flow speed of the gas and liquid, and enabling the gas and liquid to be fully mixed in the dissolved gas space 12 to increase the amount of bubbles in the liquid to improve the cleaning properties of the object.

[0063] Therefore, by setting the opening direction of the mixing inlet 122 and the opening direction of the liquid outlet 15 to be opposite in the vertical direction, the gas and liquid can flow in opposite directions, thereby increasing the flow path of the liquid and gas and improving the mixing of the gas and liquid.

[0064] In some embodiments, the bubble generating module 101 is further provided with a Venturi pipe 2, which is provided with an air inlet 21 and a liquid inlet 22. The air inlet 21 is connected to the air inlet 13, the liquid inlet 22 is connected to the liquid inlet 14, and the Venturi pipe 2 is connected to the mixing inlet 122.

[0065] Specifically, such as Figure 1 As 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. The outlet end of the Venturi pipe 2 is connected to the mixing inlet 122, so that the Venturi pipe 2 is connected to the dissolved gas space 12.

[0066] 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 inlet 122, where the mixing of gas and liquid continues.

[0067] 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.

[0068] The Venturi pipe 2 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.

[0069] 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.

[0070] Specifically, the air inlet 13 is communicated with the air 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, so that the gas at the air inlet 13 can be introduced into the air inlet hole 21 through the air inlet channel 3, and the air dissolving space 12 can be communicated with the Venturi pipe 2 through the air inlet channel 3, so that the air in the air 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.

[0071] In this way, the external air can be directly introduced into the Venturi pipe 2 through the air inlet channel 3, and the gas in the air dissolving space 12 can also be introduced into the Venturi pipe 2, which improves the gas supply mode of the Venturi pipe 2 and can recycle the remaining gas in the air dissolving space 12, thereby improving the air utilization rate of the whole system and improving the mixing of the gas and the liquid.

[0072] 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 with the bubble generating module 101.

[0073] In other embodiments, the liquid inlet channel 4 is further formed in the bubble generating module 101, and the liquid inlet channel 4 is communicated between the liquid inlet hole 22 and the liquid inlet 14.

[0074] Specifically, the liquid inlet channel 4 is arranged upstream of the Venturi pipe 2, one end of the liquid inlet channel 4 is connected with the liquid inlet 14, and the other end is connected with the liquid inlet hole 22, so that the liquid at the liquid inlet 14 can be introduced into the liquid inlet hole 22 through the liquid inlet channel 4, and the liquid can be introduced into the Venturi pipe 2. The liquid inlet 14 of the liquid inlet channel 4 can be communicated with a tap water pipe, or can be connected with a water tank arranged in the bubble generating module 101, and the liquid inlet channel 4, the Venturi pipe 2 and the air dissolving space 12 are sequentially communicated along the flow direction of the liquid, so that the tap water or the water stored in the water tank can flow into the Venturi pipe 2 through the liquid inlet channel 4, and the liquid and the gas are fully mixed in the Venturi pipe 2 and the air dissolving space 12, and then the mixed gas-liquid mixture is introduced into the washing cavity of the equipment.

[0075] Therefore, through the above arrangement, the mixing of the gas and the liquid can be realized during the water supply to the washing cavity of the equipment, and the liquid wrapped with the gas can be provided to the washing cavity, thereby improving the cleaning characteristics of the washing articles.

[0076] 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 with the bubble generating module 101.

[0077] In some embodiments, the liquid inlet channel 4 is provided with a flow meter 8. In the present embodiment, the flow meter 8 is used to measure the flow of liquid. The flow meter 8 can measure the flow of fluid in the pipeline according to the physical law of fluid movement, so as to facilitate the understanding of the real-time flow of liquid.

[0078] The flow meter 8 is detachably connected to the liquid inlet channel 4. During use, the liquid inlet channel 4 is filled with liquid, and the water inflow of the liquid inlet channel 4 can be detected through the flow meter 8. The flow meter 8 can accurately measure the flow of fluid and provide accurate flow data to ensure that the water inflow 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 mixing process of the liquid and the gas.

[0079] 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 unidirectional from the gas 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 gas inlet hole 21.

[0080] Specifically, the first one-way valve 31 is used for the unidirectional 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 gas inlet channel 3. The first one-way valve 31 is detachably connected to the top of the gas dissolving space 12 and located near the gas inlet 13. When the inside of the gas 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. In this way, the gas can be unidirectional from the gas inlet 13 to the gas inlet hole 21.

[0081] Further, when water is filled, the first one-way valve 31 is in a closed state, and the gas dissolving space 12 forms a sealed space. After the water filling 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 gas inlet channel 3 from the gas inlet 13 through the first one-way valve 31, thereby realizing the gas supply of the venturi pipeline 2 and realizing the mixing of the gas and the liquid in the next step.

[0082] When the liquid inlet channel 4 is filled with water, and when the gas dissolving space 12 is in a negative pressure state, it is easy to form a siphon effect. At this time, the larger external air pressure opens the first one-way valve 31, and the gas flows into the gas dissolving space 12 to balance the pressure difference, thereby playing a role in preventing siphon.

[0083] Therefore, by arranging the first one-way valve 31, the gas can flow unidirectionally, and the gas can be continuously supplied to the gas inlet channel 3, thereby avoiding the reverse flow of the gas affecting the mixing of the gas and the liquid, and thereby improving the stability of the gas supply.

[0084] In some embodiments, the liquid inlet 14 and the liquid outlet 15 are both arranged at the bottom of the bubble generating module 101, and the liquid inlet 14 and the liquid outlet 15 are spaced apart and distributed, so that the liquid can flow from the bottom of the bubble generating module 101 to the liquid inlet channel 4, the Venturi pipe 2 and the gas dissolving space 12 in sequence, and the gas-liquid mixture in the gas dissolving space 12 flows downward to the bottom of the bubble generating module 101, forming a reverse U-shaped flow path, so that the distribution of multiple channels is more compact, and the occupied space is smaller, improving the overall integration.

[0085] The liquid inlet 14 and the liquid outlet 15 are both arranged at the bottom of the bubble generating module 101, and the liquid inlet 14 and the liquid outlet 15 are spaced apart and distributed, so that the liquid can flow from the bottom of the bubble generating module 101 to the liquid inlet channel 4, the Venturi pipe 2 and the gas dissolving space 12 in sequence, and the gas-liquid mixture in the gas dissolving space 12 flows downward to the bottom of the bubble generating module 101, forming a reverse U-shaped flow path, so that the distribution of multiple channels is more compact, and the occupied space is smaller, improving the overall integration.

[0086] The liquid inlet 14 and the liquid outlet 15 are both arranged at the bottom of the bubble generating module 101, and the liquid inlet 14 and the liquid outlet 15 are spaced apart and distributed, so that the liquid can flow from the bottom of the bubble generating module 101 to the liquid inlet channel 4, the Venturi pipe 2 and the gas dissolving space 12 in sequence, and the gas-liquid mixture in the gas dissolving space 12 flows downward to the bottom of the bubble generating module 101, forming a reverse U-shaped flow path, so that the distribution of multiple channels is more compact, and the occupied space is smaller, improving the overall integration.

[0087] In some embodiments, the bubble generating device 100 further comprises a breather module 102, and the breather module 102 is integrally arranged with the bubble generating module 101. The breather module 102 further forms an exhaust space 5 therein, and the exhaust space 5 is provided with an exhaust inlet 51 and an exhaust outlet 52. The exhaust inlet 51 and the air inlet 13 are both in communication with the exhaust space 5.

[0088] Specifically, the exhaust space 5 is used for exhausting gas, and a part of the structure of the breather module 102 can be formed as the exhaust space 5. As shown in FIG. 1, the exhaust space 5 is provided with the exhaust inlet 51, and the exhaust inlet 51 is used for exhausting gas. The exhaust space 5 is further provided with the exhaust outlet 52 for communication with the outside space. In this way, the gas entering the exhaust inlet 51 is exhausted from the exhaust outlet 52 of the breather module 102. Figure 1

[0089] ​Furthermore, after connecting the bubble generator 100 to some cleaning equipment, during the cleaning process, the cleaning space will generate gas with heat, and the pressure will increase as the gas increases. At this time, 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, thereby reducing the pressure of the cleaning process, improving the safety and stability of cleaning items, and the structure is reasonable and reliable.

[0090] Furthermore, the exhaust inlet 51 and the air inlet 13 are respectively connected to the exhaust space 5. In this way, the gas drawn in by the exhaust inlet 51 can enter the exhaust space 5. After the first one-way valve 31 is opened, the gas in the exhaust space 5 can enter the dissolved gas space 12 or the air inlet channel 3 through the air inlet 13, thereby providing gas to the Venturi pipe 2. This enables the gas in the exhaust space 5 to be recycled, thus improving the gas utilization rate.

[0091] In some embodiments, a drainage channel 6 is also formed within the respirator module 102. The drainage channel 6 has a drainage inlet 61 and a drainage outlet 62, and the drainage channel 6 is connected to the exhaust space 5.

[0092] Specifically, the drainage channel 6 is used to discharge liquid, and a portion of the structure of the respirator module 102 can be configured as the drainage channel 6, wherein, for example... Figure 1 As shown, the drainage channel 6 is provided with a drainage inlet 61 that connects to an external waterway. 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 a drain pipe through the drainage outlet 62. In this way, at the end of the washing process, the washed wastewater enters the drainage channel 6 from the drainage inlet 61 and is then discharged to the outside of the breather module 102 through the drain pipe, thus 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.

[0093] 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.

[0094] 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.

[0095] In some embodiments, a connecting channel 7 is further formed in the respirator module 102, the connecting channel 7 has a connecting inlet 71 and a connecting outlet 72, the connecting inlet 71 is communicated with the exhaust space 5, and the connecting outlet 72 is communicated with the drainage flow channel 6.

[0096] Specifically, the connecting channel 7 is located between the exhaust space 5 and the drainage flow channel 6, and the connecting channel 7 is communicated with the exhaust space 5 through the connecting inlet 71 and communicated with the drainage flow channel 6 through the connecting outlet 72, wherein the connecting channel 7 is located at the side of the exhaust space 5 away from the gas dissolving space 12, and the connecting 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 connecting channel 7.

[0097] Further, during the washing process and when the drainage flow channel 6 is draining, a negative pressure state is formed inside the drainage flow channel 6, which is easy to 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 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.

[0098] Wherein, the exhaust outlet 52 of the exhaust space 5 is communicated with the external space, that is, when the exhaust space 5 does not exhaust, 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 connecting channel 7, which can also achieve the gas supply to the connecting channel 7.

[0099] Therefore, 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.

[0100] Wherein, the connecting 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.

[0101] In some embodiments, the connecting inlet 71 is provided with a second one-way valve 73, and the second one-way valve 73 is configured to allow one-way conduction from the exhaust space 5 to the connecting channel 7.

[0102] Specifically, the second one-way valve 73 is used for one-way conduction of gas, as shown in Figure 1 The second one-way valve 73 is arranged at the connecting inlet 71 of the connecting channel 7, and the second one-way valve 73 is detachably connected to the top of the connecting channel 7, and the second one-way valve 73 is configured to be opened under the action of negative pressure at the connecting inlet 71, that is, when the inside of the connecting channel 7 and the external space form a pressure difference, the second one-way valve 73 is opened by the pressure difference, so that the gas is one-way conducted from the exhaust inlet 51 to the connecting inlet 71.

[0103] Further, during the washing process, and when the siphon effect of drainage occurs, the external larger air pressure opens the second one-way valve 73, 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 as to balance the air pressure inside the drainage flow channel 6, thereby playing a role in preventing siphon.

[0104] Therefore, by arranging the second one-way valve 73, the gas can flow in one direction, and the air pressure of the drainage flow channel 6 and the external space is balanced, thereby improving the stability of liquid discharge.

[0105] 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 As shown, the drainage flow channel 6 and the exhaust space 5 are spaced apart in the up-down direction, and both 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 respirator module 102, and the gas dissolving space 12 occupies the other side of the respirator module 102, so that the integrated arrangement of the three can be achieved, 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. Therefore, more space can be used for mixing gas and liquid to improve 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 at the same time, which is reasonable in arrangement and compact in structure, and can improve the cleaning function of the article.

[0106] 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 arranged in sequence in the horizontal direction, and both are arranged in the horizontal direction. Therefore, when the respirator module 102 is connected with the bubble generating module 101 and the matched equipment, only the side space of the equipment can be occupied, so that the installation is more convenient and simple, the structure is more compact, the occupied space is small, and the integrated arrangement with other equipment is facilitated.

[0107] 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.

[0108] It should be noted that the gas dissolving space 12 and the drainage flow channel 6 can be integrated to provide bubble water for the equipment and discharge the liquid after washing. Meanwhile, the gas dissolving space 12 and the exhaust space 5 can be integrated to provide bubble water for the equipment and discharge the gas during the washing process. In addition, the three can be integrated to provide bubble water for the equipment and discharge the gas and liquid in the equipment, and the arrangement mode is various and can be selectively arranged.

[0109] The utility model also proposes a kind of washing equipment.

[0110] According to the washing equipment of the utility model embodiment, the device main body and the bubble generating device 100 of any one embodiment are included, a washing space is formed in the device main body, and the bubbler 9 is connected with the washing space.

[0111] Specifically, the device main body is the main structure of the washing equipment, can support the structure in the washing equipment, and can be used to install different structures, and the device main body forms a washing space, which is used to realize the washing function. The washing equipment can be a dishwasher, a washing machine or the like to realize different cleaning functions, and the washing space can be constructed as an open cavity structure for users to place items to be cleaned, and can be open to the upper side or the front side, which is convenient for users to operate in front of the washing equipment.

[0112] In addition, the bubbler 9 is connected with the washing space 11, the bubbler 9 is used to mix water and air to generate bubbles to effectively clean the items to be cleaned, i.e. the liquid containing micro-bubbles produced by the bubbler 9 is introduced into the washing space 11 to clean the items in the washing space 11.

[0113] The bubble generating device 100 is integrated in the device main body, and the bubbler 9 is connected with the gas dissolving space 12, which can mix gas and liquid in the gas dissolving space 12 to form a gas-liquid mixture, and then use the bubbler 9 to produce more liquid containing bubbles for cleaning to increase the contact area of water flow and the flushing object, improve the washing effect, save water, and improve the user experience.

[0114] The exhaust inlet 51 is communicated with the washing space, and the gas in the washing space can be introduced into the exhaust space 5 from the exhaust inlet 51, and then discharged from the exhaust outlet 52 to the outside of the washing equipment, so as to reduce the pressure of the washing space, improve the safety and stability of the item cleaning, and the structure is reasonable and reliable.

[0115] Therefore, by arranging the bubble generating module 101 in the bubble generating device 100, the gas and liquid can be dissolved in the bubble generating module 101 for the washing function of the device, and the mixed liquid after dissolution can be first guided away from the liquid outlet 15 by the turbulence structure 121, and then guided towards the liquid outlet 15, so that the flow direction of the mixed liquid is in the reverse U shape. In this way, the distance of the mixed liquid to the liquid 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 liquid outlet 15, the flow path of the mixed liquid is increased, so that the mixed liquid can flow from the liquid outlet 15 to the bubbler 9 after sufficient fusion in the gas dissolving space 12, which improves the bubble generation amount of the bubble generating module 101 and is beneficial to improve the cleaning characteristics of the items.

[0116] The bubble generating device 100 can be detachably connected with the device body by bolts, or connected by clamping, plugging and the like, so that the bubble generating device 100 is separately detached and installed relative to the device body, and subsequent maintenance and inspection are facilitated, and the bubble generating device 100 can be integrally formed with the device body, thereby reducing the connection steps between the bubble generating device 100 and the device body and reducing the installation cost.
