Referring to fig. 8, the suction enhancement principle of the suction pipe in this embodiment is as follows:
as can be seen from the above, the first discharge electrode of the ionization device is a discharge anode, the second discharge electrode is a discharge cathode, after the air in the suction tube is ionized by the first discharge electrode and the second discharge electrode, a magnetic fluid is formed in the suction tube, the magnetic fluid has positive ions, electrons, negative ions and the like, the electrons and the negative ions move to the first discharge electrode due to the principle of like polarity repulsion and opposite polarity attraction, the positive ions move to the second discharge electrode, the movement of the ions forms a current, the direction of the current is from the first polar plate to the second polar plate, the inner side of the first magnet is an S pole, the inner side of the second magnet is an N pole, and the direction of a formed magnetic field is from the N pole to the S pole; in microscopic view, the magnetic fluid is plasma, and is subjected to lorentz force in the magnetic field, and q is the charge quantity of the plasma, v is the movement speed of the plasma, B is the magnetic field strength, and F is the lorentz force to which the magnetic fluid is subjected according to a formula F= qvB;
q and v are also difficult to estimate, but their overall characteristics are apparent, since the particles after ionization are microscopically difficult to observe. Therefore, when two particles move together, the formed current can be regarded as an electrified wire, the electrified wire is acted by ampere force in a magnetic field, the schematic diagram designed by a mechanical device and the ampere force formula f=ilb sin alpha acted by the electrified wire in the magnetic field can be known (wherein F is the resultant force acted by the magnetic fluid, I is the current in the electrified wire, L is the length of the electrified wire in the magnetic field, B is the magnetic field intensity, alpha is the included angle between the direction of the current I in the electrified wire and the direction of the magnetic field intensity B), and the magnetic field is perpendicular to the direction of the current, so sin alpha=1, and the formula is further simplified to F=ilb;
the magnitude of the ampere force in the magnetic field is related to the length and magnitude of the energized conductor (here, the forming current) and the strength of the magnetic field, and considering a strip of "particle flow" as a conductor, the magnetic fluid motion in the pipette can be controlled by the magnetic field as the control of the energized conductor in the magnetic field, and then there is the formula f=nlib, where n is the amount of current formed in the magnetic field, and when the total ampere force to which the magnetic fluid is subjected is considered as the sum of the forces to which each small segment of force Δf can be written as Δf=nl Δlb, and the sum as ΣΔf.
Further, when the direction of the resultant force ΣΔf coincides with the suction direction of the suction pipe (the direction of the movement velocity v of the gas in the suction pipe), the suction force of the suction pipe increases, and referring to fig. 1, the air enters the suction pipe (the curve in the drawing is a schematic diagram of the air movement route), the positive y-axis direction is the direction of the magnetic field B, the positive z-axis direction is the direction of the current I in the "wire", and the positive x-axis direction is the direction of the original flow velocity v of the gas in the suction pipe. The ionization device and the magnetic field intensity are regulated, and the direction of the x axis is the same as the direction of the sum force Sigma delta F borne by the magnetic fluid, so that the wind power of the suction pipe can be increased through the embodiment, and the suction force of the suction pipe is enhanced.
Further, in order to achieve an increase in suction force of the suction tube, besides by adjusting the magnetic field strength, it can be adjusted by the following parameters: the method comprises the steps of controlling the distance between a first discharge electrode and a second discharge electrode, adjusting the ionization degree, controlling the discharge intensity of a nanosecond pulse power supply, controlling the discharge frequency of the nanosecond pulse power supply and the like, adjusting parameters such as the length, the size and the number of formed currents through controlling an ionization device, and controlling the flow of magnetic fluid through controlling the magnetic field intensity after the adjustment, so that suction enhancement of a suction pipe is realized.
