It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The same reference numbers will be used throughout the drawings to refer to the same or like parts.

It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Further, the description of the upper, lower, left, right, etc. used in the present invention is only with respect to the positional relationship of the respective components of the present invention with respect to each other in the drawings.

Referring to fig. 1 to 13, a micro-nano bubble generation connector includes a jet piece 1, a bubbler 2, and a gas-liquid outlet connector 3.

With reference to fig. 1 to 4, the jet member 1 is provided with a gas-liquid access channel 11, a jet channel 12 and a diffusion chamber 13, which are connected in sequence, and one end of the gas-liquid access channel 11, which is far away from the jet channel 12, is provided with a first gas-liquid inlet 111 for inputting gas-liquid mixed fluid; the cross-sectional area of the jet flow channel 12 is smaller than the cross-sectional areas of the gas-liquid access channel 11 and the diffusion chamber 13. The gas-liquid mixed fluid enters from the first gas-liquid inlet 111 and sequentially passes through the gas-liquid access channel 11, the jet flow channel 12 and the diffusion chamber 13, and the cross-sectional area of the jet flow channel 12 is smaller than that of the gas-liquid access channel 11, so that the pressure is suddenly increased after the gas-liquid mixed fluid enters the jet flow channel 12, the flow speed of the jet flow channel 12 is increased, the water flow impact force is improved, and the subsequent foaming is facilitated. After entering the diffusion chamber 13 from the jet flow channel 12, the gas is rapidly sprayed out, and the pressure is suddenly reduced because the cross-sectional area of the jet flow channel 12 is smaller than that of the diffusion chamber 13, so that negative pressure is formed at the outlet of the jet flow channel 12, and the gas is further dissolved in the water.

The gas-liquid mixed fluid is water with bubbles. The gas-liquid inlet of the water inlet joint can be connected with the venturi ejector, and water flow can suck air when passing through the venturi ejector, so that gas-liquid mixed fluid is formed and is input into the gas-liquid inlet of the water inlet joint. The cross-sectional area of the diffusion chamber 13 is larger than that of the gas-liquid access channel 11, so that the pressure difference is increased, and the dissolving amount of bubbles in water is increased.

Referring to fig. 1, 2, and 5 to 7, the bubbler 2 includes at least one bubbling channel 211, one end of the bubbling channel 211 is a second gas-liquid inlet 2111, the other end is a gas-liquid outlet 2112, the second gas-liquid inlet 2111 is communicated with the diffusion chamber 13, and the cross-sectional area of the bubbling channel 211 gradually increases from the second gas-liquid inlet 2111 to the gas-liquid outlet 2112. The gas-liquid mixed fluid from the diffusion chamber 13 enters the bubbling channel 211 from the second gas-liquid inlet 2111, and as the cross-sectional area of the bubbling channel 211 is gradually increased from the second gas-liquid inlet 2111 to the gas-liquid outlet 2112, the gas-water mixed volume is enlarged, the pressure is gradually reduced, the gas dissolved in the water becomes bubbles, and a large number of micro-nano bubbles are formed instantaneously in cooperation with the high-speed impact gas of the water flow. In addition, generally, when the micro-nano bubble generation connector is used, the micro-nano bubble generation connector is vertical, the jet piece 1 is arranged above, the bubbler 2 is arranged below, and because the gas slightly rises upwards, water flow impacts downwards, high-speed flowing water impacts the gas, the gas and the water flow are violently mixed, and therefore a large number of micro-nano bubbles are formed instantly. In one embodiment, the frothing channel 211 is conical. The bubble passage 211 may have only one or a plurality of passages all connected to the diffusion chamber 13.

As shown in fig. 1, 2, 8, and 9, the gas-liquid outlet 3 is provided with a gas-liquid collecting chamber 31 and a terminal connecting portion 32 for connecting to a water outlet terminal, and the gas-liquid collecting chamber 31 is communicated with the gas-liquid outlet 2112. The water outlet terminal can be a water outlet tap or a water outlet pipe of the cleaning equipment, and therefore, the terminal connecting part 32 can be arranged in a hollow tubular shape, is communicated with the gas-liquid collecting cavity 31, and can be inserted into the water outlet pipe of the cleaning equipment to realize connection. The gas-liquid collecting cavity 31 is communicated with the gas-liquid outlet 2112, and can receive the liquid (such as bubble water) containing a large amount of micro-nano bubbles generated by the bubbler 2 and input the liquid to the water outlet terminal of the cleaning device from the terminal connecting part 32. In addition, there are a plurality of bubble channels 211 on the bubbler 2, which may be 2-20, for example, 5, and in one embodiment, there are 10 bubble channels 211, and these 10 bubble channels 211 are all communicated with the gas-liquid collecting chamber 31, and one gas-liquid collecting chamber 31 is used to collect the liquid containing a large amount of micro-nano bubbles generated by each bubble channel 211, and input them together to the water outlet terminal.

Based on the structure, the water and the air can be mixed violently by accelerating the flow speed, and then the high-speed flowing water impacts the gas to generate bubbles by expanding the water and air mixing volume, so that the generated micro-nano bubbles are more in quantity and higher in efficiency, and the jet flow piece 1 and the gas and liquid outlet joint 3 are arranged and can be respectively connected with the gas and liquid supply equipment and the water outlet terminal, so that the cleaning equipment does not need to be additionally modified, and the use is more convenient.

The gas-liquid mixed fluid enters the first diffusion groove 212 from the diffusion chamber 13 and impacts on the groove wall of the first diffusion groove 212, so that the gas and the liquid are mixed together more vigorously, and the number of nano micro bubbles is increased.
