The invention relates to percussive massage devices and more particularly to a percussive massage device having a Universal Serial Bus (USB) port.
Massage is the manipulation of the body's soft tissues. Massage techniques are commonly applied with hands, fingers, or other body parts. The purpose of massage is generally for the treatment of body stress or pain. There are a wide variety of massage devices commercially available because conventional massage techniques are laborious.
However, conventional massage devices provide ineffective massages that are superficial and do not provide any real benefit. Further, conventional massage devices have only one function of massaging. Furthermore, conventional massage devices make a lot of noise in operation due to vibration of the electric motor and in turn components thereof may loosen after a period of time of use. In addition, conventional massage devices are relatively large.
Thus, the need for improvement still exists.
The invention has been made in an effort to solve the problems of the conventional art including single function, great noise, strong vibration and being relatively large by providing a percussive massage device having novel and nonobvious characteristics.
To achieve above and other objects of the invention, the invention provides a percussive massage device comprising an upper half housing, an electric motor, a lower half housing, and a handle; wherein the motor is disposed in a lower portion of the upper half housing; further comprising a plurality of first screws driven through a flange into a bottom of the electric motor; further comprising a plurality of second screws driven through the flange into the upper half housing; further comprising a third screw driven through an eccentric counterweight into the electric motor; wherein the eccentric counterweight is disposed under the flange; further comprising a plurality of fourth screws driven through a link into the eccentric counterweight; further comprising a first bearing disposed at a left side of the link; further comprising a fifth screw driven through the first bearing into the eccentric counterweight; further comprising a second bearing disposed at a right side of the link; further comprising a follower connected to the right side of the link; further comprising a sixth screw driven through the second bearing into a left side of the follower to join the follower and the link; further comprising a plurality of seventh screws driven through the lower half housing into the upper half housing to fasten them together; further comprising a plurality of rubber sleeves each put on the seventh screw; further comprising a hollow cylinder secured onto a right side of the follower and disposed at right sides of both the upper half housing and the lower half housing; further comprising a rubber pad disposed at a right end of the hollow cylinder; further comprising an applicator head threadedly fastened in the right side of the hollow cylinder; wherein the handle is extended downward from a bottom of the lower half housing; further comprising a plurality of eighth screws driven through the lower half housing into the handle to fasten them together; further comprising a rechargeable battery disposed in the handle; further comprising a USB printed circuit board (PCB) disposed under the battery at a lower portion of the handle; further comprising a USB port disposed at the lower portion of a left side of the handle and connected to the USB PCB by wire; further comprising an ammeter disposed under the USB PCB; further comprising a master PCB disposed under the ammeter; further comprising a rotating shaft disposed in the lower portion of the handle; further comprising a base disposed in the lower portion of the handle; further comprising a plurality of ninth screws driven through the base into the handle to fasten them together; further comprising an on/off switch and a tenth screw driven through the on/off switch into the base to fasten them together; further comprising a rubber cap disposed on the tenth screw; further comprising a DC rubber bar disposed on a bottom of the base; further comprising a speed controller and a speed display both disposed at left sides of the upper half housing and the lower half housing; further comprising a motor switch disposed on the left side of the upper half housing; and wherein the electric motor, the USB PCB, the ammeter, the master PCB, the speed controller, and the speed display are electrically connected to the rechargeable battery.
Preferably, the flange is rectangular and includes four shock absorbing posts at four corners thereof respectively.
Preferably, the shock absorbing posts are formed of rubber.
Preferably, further comprises a plurality of first washers each put on one of the second screws, a second washer put on the fifth screw, and a third washer put on the tenth screw.
Preferably, the rechargeable battery is a 24-volt battery.
Preferably, the link is step-shaped and has a lower left side and a higher right side.
The invention has the following advantageous effects in comparison with the prior art: a user may charge a consumed battery of a mobile phone by inserting a USB plug of the mobile phone into the USB port. The provision of the shock absorbing posts can absorb and damp shock impulses generated by the motor. Thus, components of the percussive massage device are prevented from being loosened. The link is step-shaped and has a lower left side and a higher right side. The link is used to accommodate a distance between the motor and the follower so that the percussive massage device can be made compact.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
Four shock absorbing posts 3 are provided at four corners of the rectangular flange 4 for absorbing and damping shock impulses generated by the motor 2. Thus, components of the percussive massage device are prevented from being loosened. The shock absorbing posts 3 are made of rubber and are excellent in absorbing shock.
The screw 7 is driven through each of a plurality of washers 6 and a washer 19 is put on the screw 20. The battery 32 is a 24-volt battery. The shock absorbing posts 3 are provided at four corners of the rectangular flange 4 respectively for absorbing and damping shock impulses generated by the motor 2. Thus, components of the percussive massage device are prevented from being loosened. The shock absorbing posts 3 are made of rubber and are excellent in absorbing shock.
The screw 7 is driven through each of a plurality of washers 6 and a washer 19 is put on the screw 20. The battery 32 is a 24-volt battery. The link 14 is step-shaped and has a lower left side and a higher right side. The link 14 is used to accommodate a distance between the motor 2 and the follower 10 so that the percussive massage device can be made compact.
Operation of the percussive massage device is described below. In response to activating the motor 2, the counterweight 8 rotates. And in turn, the link 14 converts the rotational motion of the counterweight 8 into a reciprocating linear motion of the follower 10. The application head 13 thus strongly moves back and forth to treat body stress or pain of a user.
The invention has the following advantageous effects in comparison with the prior art: a user may charge a consumed battery of a mobile phone by inserting a USB plug of the mobile phone into the USB port 31. The provision of the shock absorbing posts 3 can absorb and damp shock impulses generated by the motor 2. Thus, components of the percussive massage device are prevented from being loosened. The link 14 is step-shaped and has a lower left side and a higher right side. The link 14 is used to accommodate a distance between the motor 2 and the follower 10 so that the percussive massage device can be made compact.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
