DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

Embodiment 1

[0028] Referring to FIG. 1 to FIG. 5, in the embodiment of the present disclosure, a hand-held low-noise shock-absorbing electric massager includes shells and a moving shaft rod 1. A right end of the moving shaft rod 1 is provided with a massage head 17 and a left end is provided with a driving part controlling the moving shaft rod 1 to perform linear reciprocating motion. The hand-held low-noise shock-absorbing electric massager further includes a transmission module bracket 12. An outer side wall of the moving shaft rod 1 is coaxially provided with a shaft sleeve lubricating member 10. An inner side wall of the shaft sleeve lubricating member 10 is in close linear high-speed sliding fit with the outer side wall of the moving shaft rod 1. The shaft sleeve lubricating member 10 plays a guiding role, reduces the resistance during motion of the moving shaft rod 1, and reduces vibration generated between the moving shaft rod 1 and the transmission module bracket 12 during motion, such that noise is also reduced. A right end of the transmission module bracket 12 is provided with a shaft sleeve fixing cover 13. The shaft sleeve fixing cover 13 and the right end of the transmission module bracket 12 form a cavity for installation of the shaft sleeve lubricating member 10. The shaft sleeve fixing cover 13 is fixed with the transmission module bracket 12 by screws. The driving part is arranged at a left end of the transmission module bracket 12. Two sides of the transmission module bracket 12 are each provided with a first shock-absorbing member 122. An axis of the first shock-absorbing member 122 and an axis of the moving shaft rod 1 are perpendicular to each other. One end of the first shock-absorbing member 122 abuts against an inner side wall of the lower shell 2, and the other end abuts against an inner side wall of the upper shell 3. The first shock-absorbing member 122 acts on the inner side walls of the lower shell 2 and the upper shell 3 at the same time, so as to prevent the shells from generating abnormal noise and unnecessary vibrations from vibration of the moving shaft rod 1, which can improve the comfort when the user holds the massager. A sound reflection plate 22 is arranged on the inner side walls of the lower shell 2 and the upper shell 3, respectively, which reflects a sound wave in an area that generates more sound during operation to the sound-absorbing cloth cover 173 of the transmission module bracket 12, so as to prevent the sound wave from being transmitted to the outside of the inner cavity of the shell. A shock-absorbing pad 170 covers an outer surface of the massage head 17. In use, the shock-absorbing pad 170 is in direct contact with the massage area of the user, and the shock-absorbing pad 170 effectively reduces the vibration and noise generated by the electronic components in the massage head 17 during operation when the massage head 17 is in contact with the user, and improves the use comfort when in contact with the massage head 17. The shock-absorbing pad 170 is connected with the surface of the massage head 17 by pasting.

The second shock-absorbing member 11 can effectively reduce vibration when the shaft sleeve lubricating member 10 is in contact with the transmission module bracket 12 by wrapping.

[0030] Preferably, the second shock-absorbing member 11 is a silica gel ring, the shaft sleeve lubricating member 10 is a special wear-resistant alloy copper sleeve, and the filler in the annular groove 101 may be lubricating grease. The lubricating grease is one from the group consisting of lithium-based grease, calcium-based grease, aluminum-based grease, complex lithium-based grease, and complex aluminum-based grease. Friction between the body of the moving shaft rod 1 and the inner side wall of the shaft sleeve lubricating member 10 is further reduced by the lubricating grease.

[0031] Preferably, the first shock-absorbing member 122 is a silica gel column. At least three silica gel columns are arranged on one side of the transmission module bracket 12. A socket 121 for installation of each of the silica gel columns is formed in the transmission module bracket 12. Each of the silica gel columns penetrates the socket 121, and a top end of each of the silica gel columns abuts against the inner side wall of the lower shell 2 and a bottom end of each of the silica gel columns abuts against the inner side wall of the upper shell 3. The silica gel columns are installed through the through holes for easy installation by technicians.

[0032] Preferably, the transmission module bracket 12 is made of an aluminum material, so as to prevent the transmission module bracket 12 from deforming.

[0033] Preferably, the shock-absorbing pad 170 includes a sound-absorbing cloth cover 173, a sound-insulation layer 172, and a nano coating 171 arranged from bottom to top. Two sides of the sound-insulation layer 172 are respectively connected with the sound-absorbing cloth cover 173 and the nanocoating 171 by pasting.

The sound-insulation medium 175 is aluminum powder, which has excellent sound insulation performance. The nano coating 171 is a nano magnetic coating made of nano nickel powder, which improves the comfort when in contact with the epidermis of the user, and has physical magnetism. A generated magnetic field has an effect on the nervous system, heart function, blood components, endocrine function and activity of the human body. The nano magnetic coating has a thickness of 0.1 cm.

[0035] Preferably, the driving part includes a lithium battery 18 arranged on the inner side wall of the upper shell 3, a circuit board 19 arranged on the inner side wall of the lower shell 2, a motor 14 arranged on the transmission module bracket 12, and a swing rod 16 for transmission. A rotating shaft of the motor 14 is in transmission connection with an eccentric piece 15. One end of the swing rod 16 is connected with the eccentric piece 15 and the other end is connected with the left end of the moving shaft rod 1. A switch 191 is arranged on the circuit board 19. A button 20 matched with the switch 191 is arranged on the lower shell 2. The motor 14 is electrically connected with the lithium battery 18 through the circuit board 19.

The sound reflection plate 22 is arranged on two sides of the skeleton 21, respectively. The sound reflection plate 22 has a V-shaped cross section with an included angle of 110°-115°, which increases the reflection area of the sound wave. The included angle faces a surface of the transmission module bracket 12. A sound-absorbing cloth cover 173 covers the surface of the transmission module bracket 12, so as to absorb the reflected sound wave, which has the effect of silencing. Two sides of the sound reflection plate 22 are fixed with the lower shell 2 and the upper shell 3 by screws. Edges of the lower shell 2 and the upper shell 3 are fixed by screws after being buckled. Bottoms of outer side surfaces of the lower shell 2 and the upper shell 3 are both provided with an anti-skid shock-absorbing rubber strip 23, which is convenient for users to hold and use.
