Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a device for generating microbubbles. Background Art

[0002] The existing micro bubble machine includes a gas-liquid mixing tank and a pump body. For example, if the "single pump body + single gas-liquid mixing tank" solution is adopted, the gas needs to be sucked in and filled in the tank - then water is pumped to increase the pressure (there is a continuous drainage) - then air is sucked in and the water is drained. It has the following shortcomings: 1. A single pump cannot suck air while pumping water; 2. There will be a vacuum period when no micro bubble water is discharged during the suction, which is not a good experience; if the "multiple gas-liquid mixing tanks or multiple pump bodies" solution is adopted, the volume is too large, it is not easy to carry, the energy loss is large, the noise is large and the cost is high.

As required, the air inlet channel 12 is provided with three ports, one of which is connected to the outside air, and the other two ports are respectively connected to the second port A22 of the first two-position three-way solenoid valve 2 and the second air inlet channel 103.

[0032] According to the needs, the bottom and top of the gas-liquid mixing tank 6 are respectively provided with a first induction switch 65 and a second induction switch 66, which are used to sense the water level, and their signals are connected to the first two-position three-way solenoid valve 2, the second two-position three-way solenoid valve 3, the third two-position three-way solenoid valve 5, and the fourth two-position three-way solenoid valve 9. The first water inlet 11 of the gas-liquid mixing tank 6 is provided with a plurality of diverters 67 arranged on the top wall of the tank, and the diverter 67 is provided with a plurality of narrow channels, so that water (gas) passes through to generate high-speed jets and rotates the water to spray out to form fine water droplets in the spray, so that it can fully contact and fuse with the air, thereby increasing the concentration of the generated microbubble water and making the microbubble water more concentrated.

[0033] Please refer to Figure 1 , the micro-bubble generating device is in a state before startup, and at this time there is a small amount of water and gas in the gas-liquid mixing tank 6.

[0034] Please refer to Figure 2 , press the power button, and the microbubble device will generate the gas storage steps after powering on, as shown by the arrows in the figure. At this time: 1) the first two-position three-way solenoid valve 2 is switched to open the air inlet channel 12 and close the water inlet channel 11 (the first port A21 and the third port A23 are disconnected, and the second port A22 and the third port A23 are connected); 2) the second two-position three-way solenoid valve 3 (the first port B31 and the third port B33 are connected, the second port B32 and the third port B33 are disconnected), the third two-position three-way solenoid valve 5 (the first port C51 and the second port C52 are connected, the first port A21 and the third port A23 are connected) 1) The water inlet gas channel of the pump 4 (the third port D51 and the third port C53 are disconnected) is switched to open the water outlet channel and the second circulation channel 102 is closed; 2) The third port D51 and the third port C53 are disconnected) are switched to open the water inlet gas channel of the pump 4 (diaphragm pump) and the first circulation channel 101 is closed; 3) The fourth two-position three-way solenoid valve 9 (the third port D93 and the first port D91 are connected, the second port D92 and the third port D93 are disconnected) is switched to open the water outlet channel and the second circulation channel 102 is closed; 4) The pump 4 works; 5) The air is pumped into the gas-liquid mixing tank 6 by the pump 4. Since the density of air is smaller than that of water, the air is placed on the upper part of the water in the tank body. When the air fills the tank body, the water in the tank body will be discharged from the water outlet end 94.

[0035] Please refer to Figure 3After the water is drained, the second induction switch 66 is triggered, and the micro-bubble device generates water storage steps after startup, as shown by the arrows in the figure. At this time: 1) the first two-position three-way solenoid valve 2 (the first port A21 and the third port A23 are connected, and the second port A22 and the third port A23 are disconnected) switches to open the water inlet channel 11 and close the air inlet channel 12; 2) the second two-position three-way solenoid valve 3 (the first port B31 and the third port B33 are connected, and the second port B32 and the third port B33 are disconnected), the third two-position three-way solenoid valve 5 (the first port C51 and the second port C52 are connected, and the first port C51 is disconnected) and the third port C53 disconnected) switch to pump 4 (diaphragm pump) water inlet gas channel open, first circulation channel 101 closed; 3) the fourth two-position three-way solenoid valve 9 (the third port D93 and the first port D91 are connected, the second port D92 and the third port D93 are disconnected) switch to the water outlet channel open, the second circulation channel 102 closed; 4) pump 4 continues to work; 5) water is pumped into the gas-liquid mixing tank 6 by pump 4, and the water flow is compressed and rotated and sprayed out through the diverter 67 at the entrance of the tank body (the diverter is provided with several narrow channels), forming a large number of mist-like small water droplets that are fully mixed and contacted with the air in the tank. Since the density of air is smaller than that of water, a large number of water droplets are placed at the bottom of the air in the tank body and gather into water flow. Pump 4 continues to pump water to compress the air in the tank (microbubble water will also be discharged from the water outlet during the pumping process). However, since the flow rate at the water outlet 94 is much smaller than the pumping flow rate of pump 4, the air dissolves in the water to form microbubble water, which is then cut by the bubbler at the water outlet 94 to make the microbubble content in the water more sufficient.

[0036] Please refer to Figure 4 After the water is filled, the first induction switch 65 is triggered, and the microbubble device is generated to circulate the drainage and air suction step 1, as shown by the arrows in the figure. At this time: 1) the first two-position three-way solenoid valve 2 is switched to the air inlet channel 12 to open and the water inlet channel 11 to close; 2) the second two-position three-way solenoid valve 3 (the first port B31 and the third port B33 are disconnected, the second port B32 and the third port B33 are connected), the third two-position three-way solenoid valve 5 (the first port C51 and the second port C52 are disconnected, the first port C51 and the third port C53 are connected) are switched to the first circulation channel 101 of the pump 4 to open 1) The water inlet gas channel is opened and closed; 2) The fourth two-position three-way solenoid valve 9 (the third port D93 and the first port D91 are disconnected, and the second port D92 and the third port D93 are connected) is switched to the second circulation channel 102 to open; 3) The pump 4 continues to work; 4) The micro-bubble water in the gas-liquid mixing tank 6 is pumped into the water outlet through the first circulation channel by the pump 4 and cut and discharged. When the pump 4 pumps water, negative pressure will be generated in the gas-liquid mixing tank 6. The negative pressure will cause air to enter the gas-liquid mixing tank 6 through the second air inlet channel 103 provided with the second one-way valve 8, so as to achieve the effect of replenishing air in the tank.

[0037] Please refer to Figure 5After the water is drained, the second induction switch 66 is triggered for the second time, generating the microbubble device at the circulating drainage and air suction step 2, as shown by the arrows in the figure. At this time: 1.1) the first two-position three-way solenoid valve 2 is switched to the water inlet channel 11 to open and the air inlet channel 12 to close: 1.2) the second two-position three-way solenoid valve 3 and the third two-position three-way solenoid valve 5 are switched to the pump 4 to open the water inlet air channel and close the first circulation channel; 1.3) the fourth two-position three-way solenoid valve 9 is switched to open the water outlet channel and close the second circulation channel; 1.4) the pump 4 continues to work; start the circulation step water storage step - circulating drainage and air suction step one - circulating drainage and air suction step two.
