[0001] The utility model relates to the technical field of massagers, in particular to a handheld massager. Background Art

[0002] The handheld massager includes a handle, a massage head arranged on the handle, and a drive motor for driving the massage head to rotate. In the prior art, in order to achieve the rotary kneading function, gear meshing is usually adopted to drive the massage head to rotate continuously in one direction, thereby achieving kneading massage. However, if the massage head rotates continuously in one direction, the motor rotates too fast. If the massage head is pressed too tightly against the skin, there will be a feeling of pulling the skin, and the skin's epidermis may be easily abraded. Utility Model Content

[0003] The purpose of the utility model is to overcome the defects of the prior art, and provide a handheld massager. The massage head adopts a forward and reverse massage mode when working, which makes the massage more comfortable and reduces the possibility of skin abrasion.

[0004] The utility model discloses a handheld massager, comprising a handle, a massage head rotatably arranged on the handle, and a drive motor for driving the massage head to rotate, wherein an output shaft of the drive motor is provided with a transmission wheel that rotates synchronously with the transmission wheel, and the utility model is characterized in that an eccentric shaft that deviates from the axis of the transmission wheel is provided on the transmission wheel, a driven wheel is rotatably arranged on the handle, a long slot hole is provided on the driven wheel, the eccentric shaft is located in the long slot hole, and when the eccentric shaft rotates, the inner walls on both sides of the long slot hole can be squeezed to make the driven wheel reciprocate forward and reverse around its axis, and the massage head is provided on the driven wheel and rotates synchronously with the driven wheel.

[0005] By adopting the above technical solution, the transmission wheel is driven to rotate by the driving motor. At this time, the eccentric shaft will rotate eccentrically inside the long slot hole and squeeze the inner walls on both sides of the long slot hole, so that the driven wheel can rotate back and forth to achieve the effect of kneading massage. The forward and reverse kneading massage method is adopted, which is more comfortable and can also prevent skin from being abraded.

[0006] The present invention is further provided with the following configuration: the bottom of the handle is opened to form a connecting port, and the connecting port is detachably connected with an extension rod and a sealing cover that can be covered on the connecting port.

[0007] By adopting the above technical solution, when the blocking cover on the connecting port is removed, the extension rod can be connected to the connecting port to lengthen the handle. When the handle does not need to be lengthened, the connecting port can be blocked by the blocking cover.

[0008] The present invention is further provided with: the handle includes a first shell and a second shell which are arranged separately, a middle frame is clamped at the head position of the first shell and the second shell, the middle frame is provided with an assembly cavity for installing a drive motor and a transmission wheel, the middle frame is provided with a hinge shaft, and the driven wheel is hingedly arranged on the middle frame via the hinge shaft.

[0009] By adopting the above technical solution, a split assembly method can facilitate its installation and simplify the process flow. The assembly cavity can facilitate the installation of the drive motor and the transmission wheel.

[0011] By adopting the above technical solution, the middle frame can be easily assembled through the assembly axis and prevented from being separated from the handle, making it more stable when used. The angle of the middle frame can be adjusted by adopting a hinged manner, and rotation storage or angle adjustment can be achieved. The clutch and the positioning member can be engaged and disengaged to achieve angle locking and unlocking. The button allows the clutch to be driven out of the positioning member by external force, and the elastic reset member allows the clutch to be automatically reset.

[0012] The utility model is further configured as follows: the button is slidingly arranged on the first housing and abuts against the clutch member; the elastic reset member is a spring and is sleeved on the assembly shaft; one end of the spring abuts against the clutch member, and the other end abuts against the middle frame.

[0013] By adopting the above technical solution, the clutch can be squeezed to slide by pressing and sliding the button, and the spring can be compressed, so that the clutch can be separated from the positioning part, thereby unlocking it, so that the middle frame can rotate relatively to achieve storage or angle adjustment. When the button loses external force, the spring drives the clutch to approach the positioning part and locks it to prevent the middle frame from rotating. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings:

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] The present invention discloses a handheld massager, comprising a handle 1, a massage head 2 rotatably arranged on the handle 1, and a drive motor 3 for driving the massage head 2 to rotate. The output shaft of the drive motor 3 is provided with a transmission wheel 4 that rotates synchronously therewith. In an embodiment of the present invention, an eccentric shaft 5 deviating from its axis is provided on the transmission wheel 4, and a driven wheel 6 is rotatably arranged on the handle 1. The driven wheel 6 is provided with a long slot hole 61, and the eccentric shaft 5 is located in the long slot hole 61 (the eccentric shaft 5 is most preferably provided with an extrusion wheel, which can better squeeze the inner wall of the long slot hole 61, because when the eccentric shaft 5 is eccentrically rotated, it can not only move in the left and right directions, but also move in the right and left directions). The eccentric shaft 5 can be used to avoid displacement in the upward and downward directions, and the long slot hole 61 can be used to avoid it, so that the driven wheel 6 can be more stably rotated forward and reverse). When the eccentric shaft 5 rotates, it can squeeze the inner walls on both sides of the long slot hole 61 to make the driven wheel 6 reciprocate forward and reverse around its axis. The massage head 2 is provided on the driven wheel 6 and rotates synchronously with it. It is most preferred that the massage head 2 is detachably connected to the driven wheel 6. The massage head 2 is usually provided with convex points or convex columns, and then kneading massage is achieved by rotating with a height difference. Different arrangements have different massage effects. The massage head 2 is relatively detachable, so that multiple massage heads can be adapted to one body to achieve a variety of massage techniques.

[0025] By adopting the above technical solution, the transmission wheel 4 is driven to rotate by the driving motor 3. At this time, the eccentric shaft 5 will rotate eccentrically inside the long slot hole 61 and squeeze the inner walls on both sides of the long slot hole 61, so that the driven wheel 6 can reciprocate forward and reverse to achieve the effect of kneading massage. The forward and reverse kneading massage method is more comfortable and can also prevent skin from being worn.

[0026] The bottom of the handle 1 is open to form a connecting port 7, and the connecting port 7 is detachably connected to an extension rod 8 and a blocking cover 9 that can be covered on the connecting port 7. When the blocking cover 9 on the connecting port 7 is removed, the extension rod 8 can be connected to the connecting port 7 to lengthen the handle 1. When the handle 1 does not need to be lengthened, the connecting port 7 can be blocked by the blocking cover, and the extension rod 8 can be locked by means of threaded locking or positioning grooves and positioning blocks.

[0027] The handle 1 includes a first shell 11 and a second shell 12 that are arranged in a split manner. A middle frame 10 is clamped at the head position of the first shell 11 and the second shell 12. The middle frame 10 is provided with an assembly cavity for installing the drive motor 3 and the transmission wheel 4. The middle frame 10 is provided with a hinge shaft 20, and the driven wheel 6 is hingedly set on the middle frame 10 via the hinge shaft 20. The split assembly method can facilitate its installation and simplify the process flow. The assembly cavity can facilitate the installation of the drive motor 3 and the transmission wheel 4.

[0028] The assembly shaft 30 is also included, which is passed through the first shell 11 and the second shell 12. The middle frame 10 is hingedly arranged on the assembly shaft 30, and a clutch 40 is guided and slidably provided on the assembly shaft 30. The clutch 40 and the middle frame 10 can slide relative to each other axially and rotate circumferentially. A positioning member 50 is provided on one side of the clutch 40 on the first shell 11 and cooperates with the clutch 40 to achieve locking. The assembly shaft 30 also includes a button 60 for driving the clutch 40 to disengage from the positioning member 50 and an elastic reset member 70 for driving the clutch 40 to lock with the positioning member 50. The assembly shaft 30 can facilitate the assembly of the middle frame 10. It also prevents the middle frame 10 from being separated from the handle 1, making it more stable when in use. The hinged connection makes the angle of the middle frame 10 adjustable, allowing for rotational storage or angle adjustment. The clutch 40 and the positioning member 50 are engaged and disengaged to achieve angle locking and unlocking. The button 60 allows the clutch 40 to be driven by external force to separate from the positioning member 50. The elastic reset member 70 allows the clutch 40 to be automatically reset. The clutch 40 is preferably provided with a positioning block or a positioning shaft, and the positioning member 50 is preferably provided with a positioning groove. A plurality of positioning grooves are preferably provided along the circumferential direction so that the middle frame 10 can be rotated and adjusted to multiple angles.

[0029] The button 60 is slidably arranged on the first shell 11 and abuts against the clutch 40. The elastic return member 70 is a spring and is sleeved on the assembly shaft 30. One end of the spring abuts against the clutch 40, and the other end abuts against the middle frame 10. By pressing and sliding the button 60, the clutch 40 can be squeezed to slide and the spring can be compressed, so that the clutch 40 can be separated from the positioning member 50, thereby unlocking it, so that the middle frame 10 can rotate relatively to achieve storage or angle adjustment. When the button 60 loses external force, the spring drives the clutch 40 to approach the positioning member 50 and lock it to prevent the middle frame 10 from rotating.
