When the jet device 10 is used, water enters from the water inlet 103 of the jet device 10, flows through the first pipe section 1011 of the jet channel 101, air is sucked from the air inlet 105 of the jet device 10 and enters the air inlet channel 102, then the air is mixed with the water, the air-water mixture flows to the water outlet 104 from the second pipe section 1012 of the jet channel 101, and flows out from the water outlet 104, the jet device 10 is simple in structure, convenient to manufacture, low in manufacturing cost and capable of improving the efficiency and quality of the air-water mixture.
According to the embodiment of the present invention, in the jet device 10, the jet channel 101 includes the first pipe section 1011 and the second pipe section 1012 by providing the jet channel 101 and the air inlet channel 102 in the jet device 10, and the first pipe section 1011 and the second pipe section 1012 are connected. The ejector 10 is internally constructed as a venturi tube, and the air inlet 105 of the ejector 10 sucks air for negative pressure due to the venturi effect. Therefore, the water flow and the gas flow of the gas-water mixed flow are increased while the air suction flow is ensured.
It should be noted here that when the restricted flow passes through the reduced flow section, the flow rate of the fluid increases, and the flow rate is inversely proportional to the flow section. While it is known from bernoulli's law that an increase in flow velocity is accompanied by a decrease in fluid pressure, a common venturi phenomenon. That is, this effect means that a low pressure is generated in the vicinity of a fluid flowing at a high speed, thereby generating an adsorption effect. A venturi can be made using this effect.
In some embodiments of the present invention, the fluidic channel 101 further comprises: a throat section 1013. The throat section 1013 is connected between the first pipe section 1011 and the second pipe section 1012, the other end of the intake passage 102 is connected to and communicates with the throat section 1013, and the flow cross section of the throat section 1013 is constant in the direction from the water inlet 103 to the water outlet 104. That is, a throat section 1013 is connected between the first pipe section 1011 and the second pipe section 1012, the other end of the intake passage 102 is connected to the throat section 1013, and the other end of the intake passage 102 communicates with the throat section 1013, and the flow cross section of the throat section 1013 is always constant. The fluidic channel 101 is simple in construction and easy to manufacture.
As shown in fig. 1, the lower end of the intake passage 102 communicates with the throat section 1013, the right end of the first pipe section 1011 of the jet passage 101 communicates with the left end of the throat section 1013, and the left end of the second pipe section 1012 of the jet passage 101 communicates with the right end of the throat, so that the flow cross section of the throat section 1013 is always constant in the left-to-right direction, and the air inlet 105 of the ejector 10 is formed with negative pressure due to the venturi effect to suck air, whereby the ejector 10 is simple in structure.
In some embodiments of the present invention, the end of the other end of the air inlet channel 102 is formed with an air outlet 1021, and the aperture of the air outlet 1021 is smaller than the inner diameter of the throat section 1013. That is, the outlet 1021 is formed at the end of the other end of the inlet passage 102 (e.g., the lower end of the inlet passage 102 shown in fig. 1), and the inner diameter of the throat section 1013 is larger than the aperture of the outlet 1021. When the ejector 10 works, the air inlet 105 is in a negative pressure state, air is sucked, the aperture of the air outlet 1021 is small, and air entering the ejector 10 is reduced, so that the phenomenon that water flow is influenced due to excessive air inlet can be avoided.
In some embodiments of the present invention, the cross-sectional area of the other end of the air intake passage 102 gradually decreases in a direction from one end of the air intake passage 102 toward the other end. That is, the cross-sectional area of the other end of the air inlet channel 102 far from the air outlet 1021 is larger than that of the other end of the air inlet channel 102 near the air outlet 1021, so that the flow rate of air is increased, and the amount of air dissolved in water is increased.
For example, as shown in fig. 1, the cross-sectional area of the lower end of the intake passage 102 (the lower end of the intake passage 102 shown in fig. 1) gradually decreases in the direction from the top to the bottom (e.g., the up-down direction shown in fig. 1). Thereby, the ejector 10 is simple in structure.
In some embodiments, the length of the first tube section 1011 is less than the length of the second tube section 1012 in a direction from the water inlet 103 towards the water outlet 104. That is, in the direction from the water inlet 103 to the water outlet 104, the length of the first pipe section 1011 is shorter, the length of the second pipe section 1012 is longer, and the length of the second pipe section 1012 is greater than the length of the first pipe section 1011. The length of the first pipe section 1011 is short, so that the flow velocity of water flow is increased rapidly, the flow velocity of water flow is increased, the length of the second pipe section 1012 is long, the accelerated water flow is buffered, and damage to the jet device 10 caused by overlarge pressure is avoided.
As shown in fig. 1, in the left-to-right direction, the length of the first pipe section 1011 is smaller, the length of the second pipe section 1012 is larger, and the length of the second pipe section 1012 is larger than the length of the first pipe section 1011. Therefore, the jet flow channel 101 of the jet device 10 is ingenious in design, and the use feeling of a user is improved.
In some embodiments of the present invention, the central axis of the fluidic channel 101 extends in a first direction and the centerline axis of the air inlet channel 102 extends in a second direction perpendicular to the first direction. That is, the central axis of the jet flow passage 101 may extend in a horizontal direction, the central axis of the intake passage 102 may extend in a vertical direction perpendicular to the horizontal direction, the central axis of the jet flow passage 101 may also extend in a vertical direction, and the central axis of the intake passage 102 may extend in a horizontal direction perpendicular to the vertical direction. Therefore, the jet flow channel 101 and the air inlet channel 102 of the jet device 10 are simple in structure and convenient to manufacture.
As shown in fig. 1, the central axis of the jet flow passage 101 extends in the horizontal direction, the central axis of the air intake passage 102 extends in the vertical direction perpendicular to the horizontal direction, water enters from the water inlet 103 of the jet flow passage 101 extending in the horizontal direction, reaches the throat section 1013, and air is sucked from the air inlet 105 of the air intake passage 102 in the vertical direction, reaches the throat section 1013, is mixed with the water, and then flows out from the water outlet 104 of the jet flow passage 101.
In some embodiments of the present invention, the cross-sectional flow area of the first pipe section 1011 decreases and the cross-sectional flow area of the second pipe section 1012 increases in a direction from the water inlet 103 toward the water outlet 104. That is, in the left-to-right direction shown in fig. 7 and 8, the flow cross-sectional area of the first pipe section 1011 on the left side is always larger than the flow cross-sectional area on the right side, and the flow cross-sectional area of the second pipe section 1012 on the left side is always smaller than the flow cross-sectional area on the right side. That is, the flow cross-sectional area of the jet flow path 101 gradually decreases and then gradually increases in the direction from the water inlet 103 toward the water outlet 104.
As the water passes through the eductor 10, the cross-sectional flow area of the first pipe segment inlet 10111 is larger and the cross-sectional flow area of the first pipe segment outlet 10112 is smaller, the cross-sectional flow area of the second pipe segment inlet 10121 is smaller and the cross-sectional flow area of the second pipe segment outlet 10122 is larger. From this, great import helps the passing through of rivers, has guaranteed that the discharge that gets into in the ejector 10 is sufficient, has avoided ejector 10 rivers unstable, because venturi effect, the pressure in choke section 1013 is great, has weakened the inspiratory capacity of booster pump, and air and hydroenergy can be better mixture, have improved the content of microbubble in the bubble aquatic.
