[specific embodiment]

At first, see also Fig. 1, be first embodiment of the present utility model, mainly include face-piece 10, drain pan 20, a motor 30, a pair of eccentric 40 to shown in Figure 3, and chape 50.

Offer three grooves on the drain pan 20 side by side, intermediary groove is used for ccontaining motor 30, and the groove on both sides is used for ccontaining eccentric 40.

Motor 30 end parts parallel are fixed one first stator 31, motor output shaft stretches out this first stator 31, and fix a drive pulley 32 on it, fixing a pair of wheel pressing shaft 34 pivots respectively in the both sides of drive pulley 32 on first stator 31, a pair of pinch roller 36 is set on the wheel pressing shaft 34 respectively and can rotates around wheel pressing shaft 34 respectively, between the pinch roller 36 and first stator 31 a pinch roller pad 37 is set, to reduce the friction between the pinch roller 36 and first stator 31.One second stator 38 places on wheel pressing shaft 34 and the drive pulley 32, is used for fixing the relative position of wheel pressing shaft 34 and drive pulley 32.

Each eccentric 40 comprises eccentric wheel carrier 42, camshaft 44 and the driven pulley 46 that is fixed together with eccentric wheel carrier 42.Fix an eccentric block 48 along camshaft 44 directions on the eccentric wheel carrier 42, eccentric block 48 weight are heavier, and are arranged on from camshaft 44 position far away, and eccentric wheel carrier 42 is stretched out at camshaft 44 two ends, it is provided with bearing 442, is with the bearing rubber sleeve on the bearing 442.

Chape 50 is enclosed on drive pulley 32 and a pair of driven pulley 46, the chape 50 1 sides part between belt pulley 32 and the driven pulley 46 that has the initiative, compress " S " shape by described a pair of pinch roller 36 respectively, it is not lax therefore to make chape 50 be in tensioned state.

During use, connect the power supply of motor 30, motor 30 rotates immediately, the drive pulley 32 that driving is fixed on its output shaft rotates, the rotation of drive pulley 32 drives a pair of driven pulley 16 by chape 50 and rotates, thereby rotate with the eccentric wheel carrier 42 that driven pulley 16 is fixed together, the eccentric block 48 that drive is fixed on the eccentric wheel carrier 42 rotates, the rotation of eccentric block 48 produces centrifugal force, realize the function of vibromassage, because eccentric block 48 is far away apart from camshaft 44 positions, so its centrifugal force that produces when rotating is big, realizes powerful massage.

See also Fig. 4 to shown in Figure 6, be second embodiment of the present utility model, the difference of itself and above-mentioned first embodiment is, drive pulley 32 be replaced by driving gear 32 ', the position of a pair of pinch roller 36 of above-mentioned installation is replaced by a pair of breast wheel 60 respectively, each breast wheel 60 comprises idler gear 62 and the counter pulley 64 that is fixed together, and increased a chape 50, idler gear 62 interlock mutually on both sides and breast wheel 60 of driving gear 32 ' respectively, on the counter pulley that is enclosed in breast wheel 60 64 and driven pulley 46 that a pair of chape 50 is tightened respectively, during use, connect the power supply of motor 30, motor 30 rotates immediately, be fixed on the driving gear 32 ' rotation on its output shaft, thereby the idler gear of interlock with it 62 rotates, driving driven pulley 16 by counter pulley 64 and a pair of chape 50 again rotates, thereby rotate with the eccentric wheel carrier 42 that driven pulley 46 is fixed together, the eccentric block 48 that drive is fixed on the eccentric wheel carrier 42 rotates, the rotation of eccentric block 48 produces centrifugal force, realize the function of vibromassage, because eccentric block 48 is far away apart from camshaft 44 positions, the centrifugal force that produces when therefore it rotates is big, realizes powerful massage.

See also Fig. 7 and shown in Figure 8, be the 3rd embodiment of the present utility model, the difference of itself and above-mentioned first embodiment is, drive pulley 32 be replaced by driving gear 32 ', the position of a pair of pinch roller 36 be replaced by respectively a pair of idler gear 60 ', a pair of driven pulley 46 be replaced by respectively driven gear 46 ', driving gear 32 ' respectively in both sides and idler gear 60 ' interlock mutually, idler gear 60 ' again respectively with driven gear 46 ' interlock mutually, during use, connect the power supply of motor 30, the rotation of motor 30 drives the driving gear 32 ' rotation that is fixed on its output shaft, thereby a pair of idler gear 60 of interlock ' rotation respectively with it, drive driven gear 46 ' rotation again, thereby rotate with the eccentric wheel carrier 42 of driven gear 46 ' be fixed together, the eccentric block 48 that drive is fixed on the eccentric wheel carrier 42 rotates, the rotation of eccentric block 48 produces centrifugal force, realize the function of vibromassage, because eccentric block 48 is far away apart from camshaft 44 positions, the centrifugal force that produces when therefore it rotates is big, realizes powerful massage.
