[0028] like Figures 1-5 As shown, this utility model provides a massager with replaceable massage heads, characterized in that it includes: a bottom shell 10, a cavity provided in one side of the bottom shell 10, a drive assembly 20 provided in the cavity, the drive assembly 20 being connected to a transmission rod 25 arranged along the width direction of the bottom shell 10, the two ends of the transmission rod 25 being connected to a shoulder massage head 30 and a neck massage head 40 respectively via an eccentric wheel 26, the shoulder massage head 30 being connected to the neck massage head 40, the bottom end of the neck massage head 40 being connected to the bottom shell 10, and the neck massage head 40 being able to drive the shoulder massage head 30 to move in a predetermined direction when it is running;

[0029] The neck massage head 40 includes a connecting part 41 and a massage part 45. The connecting part 41 and the massage part 45 are separately disposed. The end of the connecting part 41 away from the end connected to the eccentric wheel 26 is provided with a male connector 42. The male connector 42 is hollow and cylindrical. A limiting post 43 is provided at the center of the male connector 42. The bottom end of the massage part 45 is provided with a female connector 46 that is adapted to the male connector 42. A limiting groove 47 that is adapted to the limiting post 43 is provided at the center of the female connector 46. The male connector 42 and the female connector 46 are detachably connected. The limiting post 43 is inserted into the limiting groove 47 to restrict the rotation of the massage part 45 relative to the connecting part 41.

[0030] Specifically, during use, the drive assembly 20 drives the transmission rod 25 to rotate, which in turn drives the eccentric wheel 26 on it to rotate. The rotation of the eccentric wheel 26 drives the shoulder massage head 30 and the neck massage head 40 to move. The shoulder massage head 30 and the neck massage head 40 are connected together and move synchronously. To prevent the shoulder massage head 30 and the neck massage head 40 from rotating with the eccentric wheel 26, a protrusion is provided at the bottom of the neck massage head 40. This protrusion is inserted into the bottom shell 10 and restricts the rotation of the neck massage head 40 and the shoulder massage head 30 with the eccentric wheel 26.

[0031] To facilitate the replacement of massage heads according to user needs, the neck massage head 40 adopts a split structure, including a connecting part 41 and a massage part 45. The connecting part 41 is used to connect with the eccentric wheel 26, and the massage part 45 is used to massage the user's neck. A connecting male head 42 is provided at the end of the connecting part 41 away from the connection with the eccentric wheel 26. The connecting male head 42 is hollow and cylindrical. At the bottom end of the massage part 45, a connecting female head 46 is provided to fit the connecting male head 42. The connecting male head 42 can be inserted into the connecting female head 46. In order to improve the stability of the connection, the connecting male head 42 and the connecting female head 46 can be detachably connected by means of clips, screws, etc., for easy disassembly and installation. Since the connecting part 41 and the massage part 45 are separate, in order to prevent rotation between the connecting part 41 and the massage part 45, a limiting post 43 is provided at the center of the connecting male head 42, and a limiting groove 47 is provided at the center of the connecting female head 46. The post 43 is inserted into the limiting groove 47 to restrict the movement between the two and prevent interference with use. The fit between the limiting post 43 and the limiting groove 47 can be a non-circular pin fit or a snap fit between the locking block 48 and the locking groove 44. In this embodiment, a combination of both is preferred. That is, the limiting post 43 and the limiting groove 47 adopt a non-circular structure, such as a triangle, square, pentagon, hexagon, etc. The polygonal angles achieve the effect of limiting rotation. At the same time, at least one locking groove 44 is opened on the side wall of the male connector 42, and at least one locking block 48 is provided on the side wall of the female connector 46. When the male connector 42 is inserted into the female connector 46, the locking block 48 is inserted into the locking groove 44, achieving a double restriction effect, ensuring the stability of use, and without affecting the convenience of disassembly and installation. When it is necessary to replace the massage part 45, the massage part 45 can be pulled out and replaced with another type of massage part 45.

[0032] Similarly, the massage part of the shoulder massage head 30 can also be replaced. The shoulder massage head 30 is also composed of a connecting part and a massage part. The connecting part is shaped like a "7" and is connected to the transmission rod 25 at the corner via an eccentric wheel. The bottom end of the connecting part of the shoulder massage head 30 is connected to the connecting part of the neck massage head 40. The two have a linkage effect. When the connecting part of the neck massage head 40 rotates, it will synchronously drive the massage part of the shoulder massage head 30 to move up and down. The eccentric wheel of the shoulder massage head 30 will drive the massage part of the shoulder massage head 30 to move back and forth. Through linkage, the shoulder massage head 30 can move both up and down and back and forth to press the massage area and achieve a massage effect. The massage part and the connecting part of the shoulder massage head 30 are also set separately, so that the massage head can be replaced as needed.

[0033] It should be noted that the double worm gear 23 refers to the addition of a gear that meshes with the transmission gear 24 on the basis of the worm gear, so that when the double worm gear 23 is driven by the worm 22, it can synchronously drive the transmission gear 24.

[0034] Furthermore, in this embodiment, the drive assembly 20 includes: a motor 21, the output end of which is connected to a worm gear 22; a bottom shell 10 is rotatably connected to a double worm wheel 23 on one side of the worm gear; the double worm wheel 23 is drive-connected to the worm gear 22; a transmission gear 24 is also provided on the opposite side of the double worm gear on the bottom shell 10; the transmission gear 24 is drive-connected to the double worm wheel; and a transmission rod 25 is fixedly inserted through the middle of the transmission gear 24.

[0035] Specifically, the motor 21 is fixedly installed in the middle of the cavity. The output end of the motor 21 is connected to the worm 22. A double worm wheel 23 is provided on one side of the worm 22. The double worm wheel 23 meshes with the worm 22. Through the arrangement of the worm wheel and worm 22, the transmission can be achieved while also achieving a compact design and reducing the space occupied. In order to transmit power to the transmission rod 25, a transmission gear 24 is also fixedly connected in the transmission rod 25. The transmission gear 24 meshes with the double worm wheel 23. The rotation of the worm 22 drives the double worm wheel to rotate, which in turn drives the transmission gear 24 to rotate, thereby driving the rotation of the transmission rod 25. Finally, the movement of the shoulder massage head 30 and the neck massage head 40 is achieved. At the same time, in order to prevent the drive component 20 from being exposed, a cover 11 is also provided on the bottom shell 10. The cover 11 covers the drive component 20 to prevent it from contacting the outside.

[0036] Furthermore, in this embodiment, to achieve different movement trajectories for the shoulder massage head 30 and the neck massage head 40, two eccentric wheels 26 are provided. The two eccentric wheels 26 are fixedly connected to the transmission rod 25, and the two eccentric wheels 26 are respectively inclined in opposite directions. The eccentric structure allows the shoulder massage head 30 and the neck massage head 40 to achieve reciprocating motion back and forth or up and down, while the inclined structure allows the shoulder massage head 30 and the neck massage head 40 to achieve reciprocating motion left and right. The combination of the two causes the shoulder massage head 30 and the neck massage head 40 to produce arc motion during movement, making the massage effect more human-like and more comfortable. This is a common prior art, so the motion principle will not be described in detail here.

[0037] In a preferred embodiment, a Hall effect positioner (not shown in the figure) is also provided inside the bottom shell 10, and the Hall effect positioner is electrically connected to the drive assembly 20;

[0038] Specifically, the Hall positioner is used to locate the current position of the massage head. If it stops at any position, the Hall positioner can record the current position and continue running from that position the next time it starts, without having to reset before running again.

[0039] In summary, by separating the massage unit 45 and the connecting unit 41, the massage unit 45 can be replaced according to the user's needs. The rotation of the massage unit 45 is restricted by the cooperation of the limiting post 43 and the limiting groove 47, and the locking block 48 and the locking groove 44, ensuring the normal operation of the massage function. Moreover, the structure is simple and easy to operate. Only a unified interface is needed to achieve quick replacement of the massage unit 45, improving practicality and meeting different usage needs.

[0040] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
