In addition, when there is negative pressure in the air dissolving cavity 102, the air inlet control unit 12 can be opened to supplement air into the air dissolving cavity 102, so as to prevent siphon from occurring.

[0046] Optionally, the air inlet control unit 12 is a first one-way valve, wherein the first one-way valve is configured to be one-way conducted in the air inlet direction. That is, the gas outside the air inlet port 1011 can enter the air dissolving cavity 102 through the first one-way valve; when the air dissolving cavity 102 is under positive pressure or normal pressure, the first one-way valve is not opened, so as to maintain a high air dissolving rate in the air dissolving cavity 102.

[0047] In addition, the air inlet control unit 12 can also be an electrically controlled valve, which can be opened and closed according to the air pressure in the air dissolving cavity 102. Specifically, the electrically controlled valve is opened when the air dissolving cavity 102 is under negative pressure, and is closed when the air dissolving cavity 102 is under positive pressure or normal pressure. In addition, when the air pressure in the air dissolving cavity 102 is the same as the air inlet pressure (i.e. atmospheric pressure) of the air inlet port 1011, the air pressure in the air dissolving cavity 102 is normal pressure; when the air pressure in the air dissolving cavity 102 is greater than the air inlet pressure of the air inlet port 1011, the air pressure in the air dissolving cavity 102 is positive pressure.

The outlet height of the second flow channel 104 can be reduced, so as to facilitate the water inlet of the air dissolving cavity 102 and reduce the problem of overflow caused by high water level in the air dissolving cavity 102.

[0049] Optionally, the air inlet port 1011 is arranged at one side of the air dissolving cavity 102 in the left-right direction, and the air dissolving cavity 102 is arranged at the other side of the air dissolving cavity 102 in the left-right direction, so as to uniformly arrange the air inlet port 1011, the air dissolving cavity 102, the second flow channel 104, the first flow channel 103 and the like, facilitate the air inlet of the respirator 10, and improve the air dissolving rate.

[0050] In some embodiments, the second flow channel 104 includes a Venturi pipe 1041, and the first flow channel 103 communicates with the Venturi pipe 1041.

The Venturi pipe 1041 is provided with an air inlet hole, a liquid inlet hole and a mixed outlet hole, the air inlet hole communicates with the air inlet port 1011, the liquid inlet hole communicates with the liquid inlet port 1012, and the mixed outlet hole communicates with the air dissolving cavity 102.

[0051] It should be noted that the Venturi pipe 1041 is internally provided with a Venturi structure, and from the inlet to the outlet of the Venturi pipe 1041, the Venturi structure can be provided to gradually decrease and then gradually increase in cross section, so that when the liquid passes through the narrow channel, a negative pressure area can be formed in the Venturi pipe 1041, the gas in the first flow channel 103 is sucked in, and the liquid and the gas are mixed for the first time, and the mixed gas and liquid enter the gas dissolving cavity 102, and can be mixed for the second time, thereby improving the mixing characteristics of the liquid and the gas.

[0052] The gas dissolving cavity 102 is communicated with the upper end of the Venturi pipe 1041, such as Figure 1 The gas dissolving cavity 102 is distributed in the up-down direction, and the upper region of the gas dissolving cavity 102 is communicated with the upper end of the Venturi pipe 1041, so that the gas and liquid mixture in the Venturi pipe 1041 enters the upper region of the gas dissolving cavity 102, and the mixing of the gas and the liquid continues in the gas dissolving cavity 102, and flows downward along the vertical direction, which can improve the flow rate of the gas-liquid mixture, thereby improving the speed of delivering the liquid to the washing space, and improving the cleaning efficiency and cleaning quality of the articles.

[0053] Optionally, the liquid inlet 1012 is arranged at the lower part of the main body part 11, and the second flow channel 104 further comprises a water inlet section 1042, the water inlet section 1042 extends in the up-down direction, the lower end of the water inlet section 1042 is communicated with the liquid inlet 1012, and the upper end is communicated with the Venturi pipe 1041. The liquid can be conveniently introduced into the second flow channel 104 through the liquid inlet 1012, and the liquid is guided to the Venturi pipe 1041 by the water inlet section 1042, which simplifies the liquid inlet structure.

[0054] Further, the Venturi pipe 1041 is arranged at the side of the main body part 11, at least a part of the water inlet section 1042 is inclined towards the gas dissolving cavity 102 in the up-down direction, and the breather 10 further comprises a flow monitoring unit 13, the flow monitoring unit 13 is communicated with the water inlet section 1042, and at least a part of the flow monitoring unit 13 is arranged below the water inlet section 1042. The flow monitoring unit 13 is used to measure the flow of the liquid introduced into the second flow channel 104.

The flow monitoring unit 13 can measure the flow of the fluid in the pipe according to the physical law of the fluid and the flow form of the fluid, which is convenient for understanding the real-time flow of the liquid.

[0055] In some embodiments, the main body 11 further comprises an exhaust cavity 105 which is separated from the gas dissolving cavity 102, and the exhaust cavity 105 is provided with a liner interface 1051, and the air inlet 1011 is communicated with the exhaust cavity 105. By using the exhaust cavity 105, the air inlet 1011 can conveniently intake air, avoiding the problem of air inlet 1011 blockage. In addition, when the liquid level is too high due to the failure of the respirator 10, the liquid can overflow from the air inlet 1011 to the liner interface 1051, thereby avoiding the problem of external overflow of the respirator 10, and improving the stability and safety of the respirator 10.

[0056] The exhaust cavity 105 is further provided with a vent 1052, and the liner interface 1051 and the vent 1052 are spaced apart and distributed along the up-down direction. The liner interface 1051 can be arranged in the middle region of the main body 11, and the vent 1052 can be arranged in the top region of the main body 11. In the washing equipment with the respirator 10, the gas in the washing space of the washing equipment can enter the exhaust cavity 105 through the liner interface 1051, and then be discharged from the vent 1052 in the exhaust cavity 105 to the outside of the main body 11, thereby realizing the discharge of the gas. The gas outside the washing space can also enter the exhaust cavity 105 through the vent 1052, and then enter the washing space through the liner interface 1051. In addition, the vent 1052 can be communicated with the outside.

[0057] In addition, the vent 1052 and the air inlet 1011 are spaced apart and distributed in the horizontal direction, as shown in Figure 1 The vent 1052 penetrates through the main body 11 and is directly communicated with the external space. The air inlet 1011 and the vent 1052 are spaced apart and distributed. The vent 1052 and the air inlet 1011 are communicated through a first one-way valve. The air inlet 1011 can be open to one side of the vent 1052. The external air can enter the exhaust cavity 105 through the vent 1052. When the first one-way valve is opened, the gas at the vent 1052 can flow to the air inlet 1011, and then flow into the air inlet channel. When the exhaust cavity 105 needs to discharge gas, the gas in the exhaust cavity 105 is discharged from the vent 1052 to the outside of the main body 11. The flow direction of the gas is not unique, and can be selectively adjusted according to the working state of the washing equipment.

[0058] The exhaust cavity 105 is provided with a plurality of turbulence ribs 111 for blocking the gas in the exhaust cavity 105. The plurality of turbulence ribs 111 are spaced apart and distributed between the liner interface 1051 and the vent 1052. The extension direction of the turbulence rib 111 intersects with the arrangement direction of the liner interface 1051 and the vent 1052. The liner interface 1051 and the vent 1052 are distributed along the up-down direction. The extension direction of the turbulence rib 111 can be along the horizontal direction, that is, the extension direction of the turbulence rib 111 is perpendicular to the up-down direction, or the extension direction of the turbulence rib 111 is non-perpendicular to the up-down direction. The setting mode is various and selective.

[0059] The turbulence ribs 111 can include at least one located in the middle region of the exhaust cavity 105 along the left-right direction, and can also include at least one located in the side region of the exhaust cavity 105 along the left-right direction. Among them, the turbulence rib 111 located in the middle region of the exhaust cavity 105 is configured as an arc-shaped structure, and the turbulence rib 111 located on both sides of the exhaust cavity 105 is configured as a linear structure, wherein the two ends of the arc-shaped structure of the turbulence rib 111 extend towards the liner interface 1051, and the middle part of the arc-shaped structure is away from the liner interface 1051. The linear structure of the turbulence rib 111 is inclined downward in the direction towards the middle region, and when the gas in the liner interface 1051 flows from bottom to top, the gas can be blocked multiple times by the plurality of turbulence ribs 111, the gas can flow along a certain path, and the flow path of the gas can be increased.

[0060] The main body part 11 is also formed with a drainage flow channel 106, which is provided with a drainage inlet 1061 and a drainage outlet 1062, and the drainage flow channel 106 is in communication with the exhaust cavity 105.

[0061] Specifically, the drainage flow channel 106 is used for discharging liquid, and a part of the structure of the main body part 11 can be formed into the drainage flow channel 106, wherein at the end of the washing equipment, the sewage cleaned in the washing space enters the drainage flow channel 106 from the drainage inlet 1061, and then is discharged to the outside of the main body part 11 through the drainage pipe, so as to realize the discharge of the sewage. Among them, the drainage flow channel 106 can be used as the central pipeline of drainage, and the drainage flow channel 106 is also connected with a drainage pump for pumping the liquid in the washing space.

[0062] The drainage flow channel 106 is in communication with the exhaust cavity 105, so that the gas in the exhaust cavity 105 can enter the drainage flow channel 106, the gas pressure in the drainage flow channel 106 can be supplemented, the pressure of the drainage flow channel 106 can be balanced, the backflow of the drainage flow channel 106 can be avoided, and the circulation use of the gas in the exhaust cavity 105 can be realized, the utilization rate of the gas is improved, and the anti-siphon of the drainage is realized.

[0063] Among them, the drainage inlet 1061 and the drainage outlet 1062 can be arranged at the bottom of the main body part 11 and spaced apart, so as to form a reverse U-shaped liquid flow path, so that the overall structure of the channel is more compact and occupies less space, and the integration degree is improved.

[0064] The main body 11 further has a connecting passage 107 formed therein, which connects the exhaust cavity 105 and the water drainage flow channel 106. Specifically, the connecting passage 107 is located between the exhaust cavity 105 and the water drainage flow channel 106, and is in communication with the exhaust cavity 105 and the water drainage flow channel 106. The connecting passage 107 is located on the side of the exhaust cavity 105 away from the gas dissolving cavity 102, and extends vertically. In this way, the gas in the exhaust cavity 105 can be introduced into the water drainage flow channel 106 through the connecting passage 107.

[0065] Further, during the operation of the washing device, when the water drainage flow channel 106 is draining water, a negative pressure state is formed in the water drainage flow channel 106, which easily forms a siphon effect, causing the liquid drained from the water drainage flow channel 106 to flow back into the washing space. In the present embodiment, the gas is quickly introduced into the water drainage flow channel 106 through the connecting passage 107, which can supplement the gas pressure in the water drainage flow channel 106, thereby preventing the water flow from flowing back into the washing space during the water drainage process.

[0066] In some embodiments, the inlet of the communication passage is provided with a second one-way valve 15 configured to allow the gas in the exhaust cavity 105 to flow into the connecting passage 107 in one direction.

[0067] Specifically, the second one-way valve 15 is used for one-way flow of the gas, as shown in Figure 1 The second one-way valve 15 is arranged at the inlet of the communication passage of the connecting passage 107, and is detachably connected to the top of the connecting passage 107. The second one-way valve 15 is configured to be opened under the action of the negative pressure at the inlet of the communication passage, i.e., when a pressure difference is formed between the inside and the outside of the connecting passage 107, the second one-way valve 15 is opened by the pressure difference. In this way, the gas can flow from the liner interface 1051 to the connecting inlet in one direction.

[0068] Further, during the operation of the washing device, and when the siphon effect occurs during the water drainage, the larger external air pressure opens the second one-way valve 15, the gas enters the exhaust cavity 105 from the air inlet 1052, and enters the connecting passage 107 through the second one-way valve 15, so as to balance the air pressure inside the water drainage flow channel 106 and the outside space, thereby preventing the siphon effect.

[0069] Therefore, by arranging the second one-way valve 15, the gas can flow in one direction, and the air pressure in the water drainage flow channel 106 and the outside space can be balanced, thereby improving the stability of the liquid drainage.

[0070] In some embodiments, the water drainage flow channel 106 and the exhaust cavity 105 are located on the same side of the gas dissolving cavity 102, as shown in Figure 1As shown, the water drainage flow channel 106 and the air exhaust cavity 105 are spaced apart in the up-down direction and are located on the same side of the dissolved air cavity 102, so that the water drainage flow channel 106 and the air exhaust cavity 105 occupy one side of the main body part 11, and the dissolved air cavity 102 occupies the other side of the main body part 11, the integrated arrangement of the three can be realized, and the occupied space of the dissolved air cavity 102 is larger than that of the water drainage flow channel 106 and the air exhaust cavity 105, so that more space can be used for mixing of gas and liquid to improve the gas-liquid mixture required in the washing process, and the main body part 11 has gas-liquid mixing function, air exhaust function and water drainage function at the same time, which is reasonable in arrangement, compact in structure, and can improve the cleaning function of the washing equipment.

[0071] The air exhaust cavity 105 is located on the upper side of the water drainage flow channel 106, which can make the water drainage flow channel 106 drain the liquid in the washing space faster, and is beneficial to the exhaust of the gas in the washing space from the air exhaust cavity 105, so as to realize the exhaust of the gas from the upper side and the liquid from the bottom, improve the exhaust efficiency and the water drainage efficiency, and the two do not affect each other, thereby improving the working efficiency and stability of the washing equipment.

[0072] It should be noted that the dissolved air cavity 102 and the water drainage flow channel 106 can be integrated, the bubble water can be provided for the washing space, and the discharge of the liquid in the washing space can be realized; the dissolved air cavity 102 and the air exhaust cavity 105 can be integrated, the bubble water can be provided for the washing space, and the discharge of the gas in the washing space can be realized; and the three can be integrated, the bubble water can be provided for the washing space, and the gas and liquid in the washing space can be discharged, which is various in setting mode and can be selectively set.

[0073] In combination with the foregoing, in some embodiments of the utility model, in the water inlet stage, the gas enters from the air inlet 1011 through the first one-way valve first, then the liquid with a certain pressure flows into the breather 10 through the liquid inlet 1012, is metered by the flow monitoring unit 13 first, then when passing through the venturi pipe 1041, the gas in the dissolved air cavity 102 is taken into the dissolved air cavity 102 at the same time with the water through the first flow channel 103, the water is fully mixed with the gas in the dissolved air cavity 102, after the gas-liquid is fully mixed, flows to the bubble generator 14 from the liquid outlet 1013, the bubble generator 14 separates the gas-liquid mixture again to flow out the water wrapped with bubbles, and the undissolved gas enters the venturi pipe 1041 from the top of the dissolved air cavity 102 through the first flow channel 103 to continue to participate in the gas-liquid circulation process.

[0074] In addition, when tap water is needed, the bubble generator 14 can be disassembled, since the liquid outlet 1013 does not have a bubble generator bubble passage, no bubble water is generated, and after being connected with the washing cavity and other connecting pieces, it can be converted into a tap water inlet mode. The utility model can simply and quickly realize the bubble water and tap water two-state water inlet switching of the breather water inlet module, and at the same time, the utilization rate of the parts is improved.

[0075] When the water inlet stage produces siphon, the first one-way valve at the position of the air inlet 1011 is opened due to the pressure difference between the external gas pressure and the internal pressure of the cavity, and the gas flows into the inside of the dissolved gas cavity 102 to balance the pressure difference, thereby playing a role in preventing siphon. The utility model meets the air intake demand of the respirator 10, and also meets the anti-siphon function of the respirator 10 in the water inlet stage.

[0076] Optionally, the liquid inlet 1012 and the liquid outlet 1013 are arranged at the bottom of the main body part 11, and the liquid inlet 1012 and the liquid outlet 1013 are distributed with a spacing, so that the liquid flows into the liquid inlet channel, the Venturi pipe 1041 and the dissolved gas cavity 102 in turn from the bottom of the main body part 11, and the gas-liquid mixture in the dissolved gas cavity 102 flows downward to the bottom of the main body part 11 and flows into the bubbler 14 from the liquid outlet 1013, so as to form a reverse U-shaped flow path, so that the distribution of multiple channels is more compact, and the occupied space is smaller, and the overall integration is improved. The liquid outlet 1013 is arranged at the bottom of the main body part, so that the flow rate of the liquid can be improved by using the gravity of the liquid, the cleaning speed of the object is improved, and the liquid containing bubbles can enter the washing space from the bottom of the main body part, the stability of the liquid flow is improved, the possibility of liquid splashing is reduced, and the cleanliness of cleaning is improved.
