Handhold electric massage rod with variable stroke

Abstract

The invention provides a handhold electric massage rod with a variable stroke. The handhold electric massage rod with the variable stroke comprises a machine core shell body and a simulation phallus, wherein the simulation phallus is arranged at the left part of the machine core shell body in a sleeved mode, a micro direct current motor and a single-chip microcomputer control circuit panel are arranged inside the right part of the machine core shell body from left to right, a movable sliding block is arranged inside the left part of the machine core shell body, a ball screw rod is arranged in the movable sliding block, the left end of the ball screw rod is arranged at the left side inside the movable sliding block, the right end of the ball screw rod extends out of the movable sliding block and is connected with a transmission shaft of the micro direct current motor, the inside of the right end of the movable sliding block is connected with the ball screw rod through a plurality of balls and ball screw rod nuts, a sliding block position indication magnet is arranged at the bottom of the movable sliding block, a position measurement circuit panel matched with the sliding block position indication magnet is arranged inside the machine core shell body, and a plurality of magnetic induction Hall elements are arranged on the position measurement circuit panel. The handhold electric massage rod with the variable stroke is small in size, has various movement modes, and is convenient to carry and place.

Description

[0001] technical field [0002] The invention relates to an electric massage stick, in particular to a hand-held electric massage stick with a variable stroke. [0003] Background technique [0004] At present, most of the hand-held electric massage sticks use the form of vibration movement, which cannot imitate the real push-and-pull sex action; and a few electric massagers that use the form of push-and-pull movement, because their driving mechanisms are all driven by electric motors. The transmission mode of the crankshaft and the connecting rod, and in order to make the stroke reach the corresponding length (usually about 6cm), the shape of the machine is larger, which is inconvenient to make a hand-held electric massage stick, and because of the fixed stroke Turned into a monotonous repetition of actions. The above two types of products all have defects in motion form, stroke change and shape and volume in use. [0005] Contents of the invention [0006] In order t...
