Electromagnetic pumping provided with frequency-conversion circuit

Abstract

The invention discloses an electromagnetic pumping provided with a frequency-conversion circuit. The electromagnetic pumping is characterized in that the frequency-conversion circuit is used for driving the electromagnetic pumping to act, the frequency-conversion circuit at least comprises an oscillating unit circuit, a dual steady state unit circuit, and a push-pull unit circuit, wherein the oscillating unit circuit is used for oscillating an input direct current power supply to a single-phase oscillation signal; the dual steady state unit circuit is used for carrying out phase splitting on the single-phase oscillation signal to obtain an N-phase inspiring signal and an S-phase inspiriting signal; and the push-pull unit circuit is used for magnifying the N-phase inspiring signal and the S-phase inspiriting signal so as to transport the electromagnetic pumping to use, and a swing arm of the electromagnetic pumping can effectively swing. The electromagnetic pumping provided by the invention has the advantages of adjusting the high-low oscillation frequency of the oscillating unit circuit to change the reciprocating pendular speed, times and swing amplitude width in unit time of a rocking arm of the electromagnetic pumping, thereby improving or reducing absorbing pressure and discharging pressure of the electromagnetic pumping; and the electromagnetic pumping can be used in medical appliances used for human bodies such as a snot-absorbing device, a milkpump, a nose-washing device, a sprayer, a toothwash machine, and a coated tongue cleaner and the like.

Description

technical field [0001] The invention relates to an electromagnetic pump equipped with a frequency conversion circuit, in particular to an electromagnetic pump that can change the speed, frequency and swing width of the rocker arm of the electromagnetic pump to reciprocate per unit time, thereby changing the suction pressure or discharge pressure of the electromagnetic pump electromagnetic pump.

[0002] Please refer to the nasal cavity cleaning spray treatment multifunctional machine (hereinafter referred to as the first existing case) disclosed in Taiwan Patent No. 092217183, the actual function of this prior case can suck nasal mucus, clean the nasal cavity and spray the nasal cavity with medicine The water mist is used to treat diseases of the nose and throat. It has an air chamber structure and a rubber cap. Using the reciprocating expansion and contraction of the rubber cap, the inlet end of the air chamber can absorb gas, and the outlet end of the air chamber can discharge gas relatively. If the inlet end is connected with a suction device, it will have the function of sucking nasal mucus, or if it is connected with an atomizer, it will have the function of atomizing and spraying medicine; however, the power source used in this existing case is generally a motor with a rotor. When the rotor rotates, it can simultaneously drive the rotating shaft on the outside of the motor to move back and forth. The reciprocating movement of the rotating shaft is a fixed distance. The faster the rotor of the motor rotates, the greater the suction force or discharge force generated by the air chamber. , the pressure it produces is directly proportional to the flow rate, because the first existing case is a multi-functional model, it is not dangerous when it is used in spray treatment, but when it is used to suck nasal mucus, it will It has the disadvantage of damaging the nasal mucosa due to excessive suction, or when it is used to clean the nasal cavity with cleaning liquid, it will have the problem of excessive momentum and choking of the nose. This type of motor still has large power consumption, large volume, and loud noise. Suction and spray force are too large, it is easy to generate high heat, it cannot be used for a long time, and it cannot be damped. It is an unsuitable power source for medical equipment that is in contact with the human body.
