The specific embodiment

Further detail below in conjunction with the content of each accompanying drawing this utility model.

To shown in Figure 5, a kind of portable biometric active substance introducing apparatus comprises housing 10 and built-in successively circuit board 14, motor 15, oblique angle drivewheel 13, drive link 12 and piston rod 11, also comprises the micropin external member 20 that is installed in said introducing apparatus front end like Fig. 1; Said motor 15 drives 13 rotations of said oblique angle drivewheel, drives said drive link 12 then and moves up and down with said piston rod 11, and said piston rod 11 buckles with the micropin pull bar 22 of said micropin external member 20, moves up and down thereby drive each micropin 21; Said introducing apparatus is that said circuit board 14 is given in lithium ion battery 16 power supplies through being located at its tail end, thereby drive motors 15 rotations drive then that each micropin 21 moves up and down; Said circuit board 14 also is provided with the DC socket 100 of accepting the external dc power charging.

As shown in Figure 4, said introducing apparatus is provided with the button 90 that is used to open and close power supply and conversion speed gear, the top of this button 90 be provided with each speed stage one to one, transversely arranged three LED lights 110; 111; 112, these three LED lights 110,111; 112 represent third gear-at a high speed from left to right successively; Second grade-middling speed and first grade-low speed, the below of said button 90 is provided with rechargeable LED display lamp 113, and the LED light 111 of second grade-middling speed of said representative is also used as the low-voltage alarm lamp simultaneously.

As depicted in figs. 1 and 2; Both sides, said housing 10 middle part are provided with symmetric two place's arc grooves 40,30, and said housing 10 back sides are provided with and this two arc groove 40; The 3rd place's arc groove 35 that 30 positions adapt, said three place's grooves constitute the geometric modeling of being convenient to hand.

Long button 90 starts, circuit board 14 is given in lithium ion battery 16 power supplies, and circuit board 14 drives and 15 rotations of control motor; Oblique angle drivewheel 13, circuit board 14 drive and 15 rotations of control motor, and oblique angle drivewheel 13 is followed motor 15 rotations with motor 15 tight fits; Along with the rotation of oblique angle drivewheel 13, drive drive link 12 and move up and down at a high speed, this moves up and down and is delivered to micropin 21 through piston rod 11 silica gel springs; And piston rod 11 buckles with micropin 21, makes micropin 21 move up and down at a high speed.

Adjustment disk 50 passes through the screw tight fit with adjusting axle sleeve 60; Regulate axle sleeve 60 and adjusting rod 70 with the multi start thread interlock; Adjustment disk 50 is marked with the scale that calculates according to pitchometer, and when the corresponding scale spacing of rotation adjusting dish 50, adjustment disk 50 drives regulates axle sleeves 60 rotations; Because of the effect of screw thread, adjusting rod 70 will move up and down corresponding distance.

The circuit working principle:

Write the burning of formula software and go into MCU, control following function:

Long press touch-switch, promptly button 90, and start is shortly pressed the touch-switch gearshift, that is, one, two, change between third gear, third gear-at a high speed, and second grade-middling speed, first grade-low speed; First grade-low speed of start acquiescence, one grade of blue lamp 112 of normal bright No. 1 LED of state; The blue lamp 111 of normal bright No. 2 LED of second gear state, the blue lamp 110 of normal bright No. 3 LED of third gear state.

Lithium ion battery 16 power supplies, along with continuing of duty, battery electric quantity must reduce; Voltage descends, and therefore, this circuit design has low electric alarm function; When MCU detected cell output voltage and is lower than 3.3V, No. 2 LED lamps 111 can be reported to the police in flicker, this product needed charging of prompting user; When giving lithium ion battery 16 chargings, have in No. 4 LED red light 113 normal bright prompting chargings, be full of back No. 4 LED red lights 113 and go out.

Motor 15 direction of rotation: overlook clockwise direction; Motor 15 and oblique angle drivewheel 13 tight fits; Oblique angle drivewheel 13, promotes drive link 12 and moves upward to peak when height point arrives drive link 12 by overlooking the clockwise direction rotation, and when low spot arrived drive link 12, pulling drive link 12 moved to minimum point, so repeatedly; Drive link 12 interlocks with piston rod 11, drive link 12 up and down repeatedly Motion Transmission give piston rod 11, piston rod 11 is followed pumps; Piston rod 11 fastens with the pull bar 22 of micropin 21, drives micropin pull bar 22 and also pumps, and the micropin 21 of pull bar 22 other ends is along with a superhigh speed pumps.

Micropin 21 depth adjustment principles:

Overlook clockwise direction and rotate adjustment disk 50, adjustment disk 50 drives regulates axle sleeve 60 equidirectional rotations, regulates axle sleeve 60 and is stuck in the plastic parts draw-in groove, can not move up and down the rotation of same only plane; Regulate axle sleeve 60 and adjusting rod 70 with the multi start thread interlock, can not move up and down because of regulating axle sleeve 60, therefore, under the effect of screw thread, adjusting rod 70 moves upward, and overlooks when rotating counterclockwise when adjustment disk 50, and adjusting rod 70 moves downward; When adjusting rod 70 moves upward, with the shell of micropin 21 external members top upwards, then micropin 21 exposes size decreases, promptly thrusts skin depth and shoals; When adjusting rod 70 moves downward, to drop-down, then micropin 21 exposes size and becomes big, promptly thrusts skin depth and deepens with the shell of micropin 21 external members.

The characteristics of multi start thread:

1, a plurality of inlets, but double quick speed screws in;

2, the lead angle of multi start thread is greater than single thread, so multi start thread whenever revolves a week, and removable many times pitch helps quick adjustment;

3, the multi start thread lift angle is big, and when then driving threads turn, it is little to rub, and transmission efficiency is high.
