- the 555 is adapted to produce a square wave at an output thereof upon the receipt of power.
- Such square wave has a duty cycle which is determined by the selection of resistor Rl, resistor R2, and capacitor Cl, as is commonly known in the art.
- the duty cycle is preferably tailored to effect a suction/release cycle which resembles that of a child.
- Such suction/release cycle consists of an approximate 1 second suction and a 1 second release.
- the output of the 555 timer is connected to a diode Dl which is in turn connected to a base of a transistor Ql .
- the transistor Ql is connected at its collector to a solenoid in which the plunger of the electronic vent control means is situated to define a transducer.
- the transistor Ql operates as an amplified switch in that upon the receipt of a high pulse, the solenoid is actuated with a sufficient current thereby forcing the plunger against the elastomeric sheet 110. This, in turn, vents the vacuum of the first compartment 92.
- a diode D2 is coupled between the collector and the emitter of the transistor to preclude a reverse polarity voltage across transistor Ql during deactivation .
- the transistor may be removed in favor of a substitute for the 555 timer IC1 which is capable of producing sufficient current for the proper operation of the transer and solenoid combination.
- Still yet another option is to utilize a coil LI with a higher DC resistance in lieu of the transistor Ql. Both alternatives are feasible and should be designed with the amount of necessary force afforded by the plunger in mind.
- a manual vent control means may be utilized.
- such manual vent control means includes a switch SI connected between a source of power and the base of the transistor Ql .
- a switch SI connected between a source of power and the base of the transistor Ql .
- an electronic vacuum control means 150 is provided.
- Such electronic vacuum control means 150 is adapted for allowing the manual governing of the level of vacuum generated by the electric pump means. To accomplish such, the speed of the motor 124 of the electric pump means is governed. The speed of the motor 124 is controlled by means of a variable duty oscillator IC2.
- the component type of IC2 is the same as ICl.
- a plurality of resistors R4 & R5, diodes D5 & D6, and a capacitor C3 are configured to dictate the specific operation of IC2.
- a potentiometer VR1 which has an associated dial 152 available for manipulation by a user.
- the potentiometer VR1 allows a user to govern the duty cycle of the pulse which is transmitted from the output of the variable duty oscillator IC2.
- the output of the variable duty oscillator IC2 is in turn connected to the base of a transistor Q2.
- Such transistor Q2 is connected at a collector thereof to the motor 124.
- the speed of the motor 124 and the suction thereby afforded is increased and decreased upon the variation of the duty cycle via the dial.
- the average voltage or DC voltage at the output of the IC2 is proportional to the duty cycle and further the voltage delivered to the motor 124 is the amplitude of the output pulse of the oscillator IC2 minus the voltage drop across the transistor Q2.
- a diode D4 is connected between the collector and emitter of the transistor for reasons similar to that of transistor Ql .
- the frequency of the pulse at the output of IC2 has no effect on the speed of the motor 124 and therefore is deemed not critical except that lower frequencies (30Hz) result in higher available motor torque especially at lower motor speeds.
- the potentiometer is of the type equipped with a switch S2 that is open when the dial 152 is turned entirely in a clockwise direction.
- a detent is formed on the shaft of the potentiometer VR1 to indicate whether the dial is turned entirely in the clockwise direction.
- Such switch S2 allows a user to selectively supply power to the electronic components of the present invention.
- a low battery indication means 160 for alerting a user upon an available power of the battery falling below a predetermined level. While the present invention is ideally equipped to accommodate power supplied by a battery, it should be noted that the present invention may also be powered by a conventional power receptacle. While not illustrated, the present invention includes an AC adapter with an associated switch which disconnects the batteries from the associated circuitry upon the employment of the AC adapter. As shown in Figure 5, the low battery indication means includes a chip IC3 which is identical to ICl & IC2 utilized in the previous circuits.
- a light emitting diode D7 In use, when the batteries discharge to a voltage of approximately 4 Volts, a light emitting diode D7 actuates such that it is visible to a user.
- the ratio of a pair of associated resistors R7 & R8 along with the zener diode D8 determine the threshold voltage at which the light emitting diode is actuated.
- the present invention is equipped with numerous features for affording high efficiency.
- the apertures 74 & 102 of the upper and lower housing 90 are .095 in diameter and the inlet 62 and exhaust port 96 of the electric pump means are no less than .20 inches, inside diameter. This is to minimize pressure loss as air passes therethrough.
- the amount of the volume required to be evacuated is reduced thus lessening the amount of power required.
