Embodiment Construction

[0013] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0014] combine Figure 1~5 , the present invention can adopt common 220V AC voltage, and the experimental environment is loose. The bubble generating circuit and control circuit are integrated inside the bubble generating device, providing an intuitive and friendly operation panel, which is easy to operate and easy to master, allowing researchers to devote more energy to the experiment without being affected by tedious experimental operations. The original low-voltage double-adjustable design composed of sliding rheostats, adjusting knobs, power output voltmeters, charging capacitors, charging voltmeters and charging switches can specify the DC output voltage that meets the experimental requirements within the range of 0-200V, and observe in real time Capacitor charging, and when the charging voltage reaches a predetermined value, the charging switch is closed to...

Abstract

The invention aims at providing an adjustable low-voltage bubble generator which comprises an alternate current to direction current power supply, a capacitor, a slide rheostat, current limit resistors, a protection resistor, alternate current contactors, a voltmeter, a charge switch, a discharge switch, a charge indicator, a discharge indicator and a power supply indicator, wherein an input terminal of the alternate current to direct current power supply is connected with an alternate current socket, the power supply indicator is connected in parallel with an input terminal of the alternate current to direct current power supply, an output terminal of the alternate current to direct current power supply is connected with the current limit resistor, the slide rheostat and another current limit resistor sequentially in series to form a closed loop circuit, the protection resistor, the capacitor and the first alternate current contactor are sequentially connected in series and then are connected with the slide rheostat in parallel to form the charge circuit, and the capacitor is connected with a discharge output terminal and the second alternate current contactor in series to form the discharge circuit. Compared with the prior bubble generator, the adjustable low-voltage bubble generator has the huge advantages on the aspects of operation, repeatability, safety, experimental period and experimental cost.

Description

technical field [0001] The invention relates to a bubble generating device. Background technique [0002] The dynamic characteristics of air bubbles in water have always been an important basic issue concerned by various research fields of modern science. There are researches and applications on air bubbles in various fields such as ships, oceans, medical treatment, and industry. In the field of ships, air bubbles can increase the speed of the ship by reducing the contact area between the hull and the water surface, and the air bubbles formed by the propeller of the ship are the main factor for damage to the propeller; in the ocean field, the air bubbles generated by the breaking of waves are the main way to absorb carbon dioxide; In the medical field, the contrast of ultrasonic imaging can be increased by injecting microbubbles into the blood; in other industrial fields, the application of bubbles also includes ultrasonic cavitation bubble cleaning, environmental protection...
