Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.

As shown in fig. 1-5, the technical solution of the present invention provides a handheld treatment head, which comprises an upper casing 1, a lower casing 2, a driving assembly disposed between the upper casing 1 and the lower casing 2, a transmission assembly 4 in threaded connection with the driving assembly, a mounting sleeve 10 for mounting the transmission assembly 4, and a connecting seat 14 in threaded connection with the transmission assembly 4 for fixing a massage head. Go up casing 1 and casing 2 down and constitute the shell structure of treatment head jointly, casing 2 is last to have handheld position down simultaneously, the treatment head of this scheme compares in prior art, cancel flexible axle structure, concentrate on power component in the cavity of last casing 1 and casing 2 formation down, regard as power source with drive assembly, drive 4 vibrations rather than being connected, and then transmit this vibration to with the fixed overhead massage of connecting seat 14 (not given in the massage head picture), the degree of integrating is high, long service life.

Drive assembly 4 includes along the first bearing 5 and the second bearing 6 of same axis setting, passes in proper order first bearing 5 with bent axle 7, the setting of second bearing 6 are in on bent axle 7 and be located first bearing 5 with eccentric wheel 8 between the second bearing 6, and with connecting seat 14 threaded connection's vibration ring 9, first bearing 5 sets up in the installation cover 10, vibration ring 9 with installation cover 10 is connected through 15 rings of rubber sleeve.

The driving assembly drives the crankshaft 7 to rotate, so that the eccentric wheel 8 fixed on the crankshaft rotates synchronously, and because of the structural characteristics of the eccentric wheel 8, stress difference exists at each point during rotation, so that the vibration ring 9 connected with the crankshaft 7 through the second bearing 6 generates vibration, and because the vibration ring 9 is in threaded connection with the connecting seat 14, the vibration is transmitted to the massage head installed on the connecting seat 14. The rubber sleeve 15 realizes the integrated connection of the vibration ring 9 and the mounting sleeve 10, and meanwhile, the rubber sleeve 15 has certain deformation capacity, so that the vibration ring 9 can vibrate smoothly.

The end part of the mounting sleeve 10 is provided with an annular bayonet 11, the end parts of the upper shell 1 and the lower shell 2 are inserted into the annular bayonet 11, an annular mounting groove 12 is formed in the opposite side of the annular bayonet 11 on the mounting sleeve 10, and the eccentric wheel 8 is located in the annular mounting groove 12. Installation cover 10 and last casing 1 and lower casing 2 joint have guaranteed the wholeness between the two for installation cover 10's installation is more firm, avoids the vibration of vibration ring 9 and leads to installation cover 10 not hard up, sets up annular mounting groove 12 simultaneously and provides installation space for eccentric wheel 8, and compact structure rationalizes and utilizes installation space.

A thread groove 13 is formed in one side, away from the mounting sleeve 10, of the vibration ring 9, an external thread is arranged on one side of the connecting seat 14, one side of the connecting seat 14 is screwed into the thread groove 13 of the mounting sleeve 10, and a thread groove 13 used for being connected with a massage head is also formed in the other side of the connecting seat 14. The vibration ring 9 and the massage head are both in a threaded connection mode, so that the installation and the disassembly are convenient.

The rubber sleeve 15 is arranged at the junction of the mounting sleeve 10 and the vibration ring 9 and is fixed by gluing. The treatment head of this scheme only has above-mentioned one and need beat and glue fixed position, compares in prior art's treatment head, beats and glues the position and significantly less, avoids the problem of coming unstuck, and is whole more firm.

The driving assembly comprises a driving motor 3, a shaft sleeve 16 is fixedly connected to an output shaft of the driving motor 3, internal threads are arranged in the shaft sleeve 16, a threaded portion 17 is arranged on the crankshaft 7, and one end of the crankshaft 7 is inserted into the shaft sleeve 16 and is in threaded connection with the shaft sleeve 16. When transmission assembly 4 needs to be dismantled, it is not hard up only to need to beat the department of gluing, then holds connecting seat 14 department, and driving motor 3 rotates this moment, alright make the screw thread portion 17 of bent axle 7 back-out from axle sleeve 16, and then dismantle transmission assembly 4 together with connecting seat 14, compare in the treatment head that the integration set up, it is more convenient to dismantle.

A connecting column 18 is arranged on one side, away from the output shaft, of the driving motor 3, a fan 19 is connected to the connecting column 18 in a threaded manner, and a heat dissipation screen plate 20 is arranged on the lower shell 2 and on the side opposite to the fan 19. The electric fan 19 rotates by the rotation of the driving motor 3, and the heat is discharged from the heat dissipation screen plate 20.
