Background technology

Have the conduction of kind more than 180 neural in people's the auditory meatus, and microcirculation is very abundant, thereby massage perhaps stimulate auditory meatus that the microcirculation enhancing audition of improving ear is had certain assosting effect.Safe physical therapy to ear is extremely important with health care; People's earpick uses instrument or materials such as matchstick, toothpick, hard ear spoon, hard cotton rod always for a long time, and there are very big potential safety hazard in these conventional tool and material, cause external auditory meatus damage, pain easily; Even penetrate tympanum easily; Not only can not effectively clean auditory meatus, solve the problem that auditory meatus is itched, more can't ensure pleasant sense.And along with transition of age, the not busy amusement of body, cosmetology industry flourish, people more and more pay attention to for not busy enjoyment of body, and the enjoyment of that part warmth sensation also makes it become the requisite project of the not busy industry of current body during earpick.But, because the difference of each one auditory meatus physiological structure, and the difference of service personal's nursing technique, the safety and the comfort sense of auditory meatus nursing all can't be ensured.Thus, people take off always and hope a kind of safe, convenient, pleasant auditory meatus cleaning massage soil tool.

The utility model content

The purpose of this utility model is to provide a kind of earphone of scratching, and this utility model is applicable to that the auditory meatus of human body is inner, and auditory meatus is massaged and cleaned, and when auditory meatus is done health care, can bring happy joyful body and mind to enjoy to auditory meatus; Simultaneously, use this utility model to scratch the disclosed shaft coupling connected mode of earphone, can conveniently change massage bar.

A kind of earphone of scratching; Comprise housing, battery, reducing motor, the first lock ring spring, shaft coupling, the second lock ring spring, massage bar; Said reducing motor, battery are fixedly connected on said enclosure interior; Said shaft coupling is connected on the motor output shaft of said reducing motor, and an other side of said shaft coupling connects said massage bar; Be provided with first open slot, second open slot along its contour direction on the said shaft coupling; Said first open slot by the end face of said shaft coupling to extending below; Said second open slot is extended upward by the other end of said shaft coupling; First periphery of said shaft coupling is provided with the first lock ring spring, and second periphery of said shaft coupling is provided with the second lock ring spring; Said motor output shaft, shaft coupling, massage bar constitute that coaxial connection, are provided with pilot hole at the head of said housing, and said massage bar passes said pilot hole.

Preferably, said housing comprises: first housing, second housing, said first housing is fixed on said second housing.

Preferably, said housing also is connected with battery cover, and said battery cover is positioned at the position at said battery place.

Preferably, said massage bar comprises: thick rod, thin rod, in the end of said thick rod and on axis direction, offer open slot, said thin rod is inserted in the said open slot.

Preferably, the connecting portion of said first connecting hole and massage bar has identical basic size.

Preferably, said second connects and said motor output shaft, has identical basic size.

Compare with conventional art, the beneficial effect of this utility model is:

1, is provided with first open slot, second open slot along its contour direction on the said shaft coupling, makes first connecting hole of said shaft coupling and second connecting hole can have certain elasticity.Outside at first connecting hole; Promptly first periphery is provided with the first lock ring spring; The said first lock ring spring is that said first connecting hole provides the pressure that shrinks to the center, when in said first connecting hole, inserting said massage bar, makes both have tighter matching property; Outside at second connecting hole; Promptly second periphery is provided with the second lock ring spring; The said second lock ring spring is that said second connecting hole provides the pressure that shrinks to the center, when in said second connecting hole, inserting said motor output shaft, makes both have tighter matching property.The advantage of the working method of this shaft coupling is that said massage bar can be extracted or assemble up like a cork.

2, said pilot hole is set on said housing, improves the axiality of said massage bar and motor output shaft.

3, the elasticity of first connecting hole and second connecting hole on the said shaft coupling of the further enhancing of employing lock ring spring drives said shaft coupling, massage bar realization rotation synchronously by said reducing motor.Because said massage bar is in the auditory meatus internal work, needed moment of torsion is very little, and this of said shaft coupling kind of working method can realize being connected said motor output shaft and said massage bar with simple principle comparatively; In overload, said massage bar can spin in said shaft coupling inside at the inner perhaps said motor output shaft of said shaft coupling, and massage bar is had safety protection function.
