detailed description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, in which the advantages and features of the present invention can be more readily understood by those skilled in the art.

As shown in FIG. 1 to FIG. 2, a variable-stroke hand-held electric massage stick includes a movement housing 1 And a simulation penis 4, the simulated penis is sleeved on a left side portion of the movement case, and the inside of the right side portion of the movement case 1 is provided with a micro DC motor 6 and a single chip microcomputer control circuit board from left to right. 5; inside the left part of the movement housing 1 is provided with a motion slider 2, inside the motion slider 2 is provided with a ball screw 10, the left end of the ball screw 10 is placed on the left side of the inside of the motion slider 2, The right end extension motion slider 2 is connected to the transmission shaft of the micro DC motor 6, and the inside of the right end of the motion slider 2 is connected to the ball screw 10 through a plurality of balls 12 and a ball screw nut 11; the bottom of the motion slider 2 A slider position indicating magnet 7 is disposed, and the movement housing 1 is internally provided with a position measuring circuit board 8 that cooperates with the slider position indicating magnet 7, and the position measuring circuit board 8 is provided with a plurality of magnetic induction Halls. The power input line and the signal input/output line of the micro DC motor 6 and the position measuring circuit board 8 are respectively connected to the single-chip microcomputer control circuit board 5; the left end of the dummy penis 4 is provided with a fixing screw 13, It is inside the left end of the motion slider 2 The fastening nut 14 is fixedly connected. The movement housing 1 is provided with a circuit switch button 51 and a sport mode button 52 connected to the single-chip microcomputer control circuit board 5.

The motion slider 2 is slidably coupled to a sliding slot in the movement housing 1. The single-chip microcomputer control circuit board 5 is connected to the DC power input socket 3. The plurality of magnetic induction Hall elements 9 are equally spaced on the position measuring circuit board 8, wherein the magnetic induction Hall elements at the left and right ends respectively correspond to the end point and the starting point of the motion slider 2.

The working principle of the embodiment of the present invention is: Connect the power socket 3 to the DC power source, and press the circuit switch button 51 on the single-chip microcomputer control circuit board 5 to initialize the position of the whole circuit and the moving parts. The specific method is: sensing the slider position by the magnetic induction Hall element 9 on the position measuring circuit board 8. The magnetic signal of the indicating magnet 7 is set to determine whether the moving slider 2 is at the starting position of the stroke. If not, the single-chip microcomputer control circuit board 5 activates the micro-DC motor 6 until the dragging motion slider 2 returns to the starting point of the stroke and stops. After entering the static standby state, and then the user presses the sport mode button 52, the single-chip microcomputer control circuit board 5 selects the motion mode selected when the sport mode button 52 is pressed (each press selects a different motion mode), The motion mode program is set in the single-chip microcomputer control circuit board 5, and the micro DC motor 6 is driven to rotate the ball screw 10 in the forward and reverse directions, thereby dragging the motion slider 2 through the ball screw nut 11 in the movement case. The reciprocating linear motion is performed in the sliding groove in the body 1 to drive the simulation penis 4 to synchronize.
