[0030] Reference Figures 1 to 4 In one embodiment of the present invention, a head massage device includes:

[0031] The housing 100 serves as the structural foundation and has a fixing cylinder 110 at the front end;

[0032] The linear drive 200 is disposed in the housing 100 and is telescopically driven by a drive shaft 210;

[0033] A mobile power supply 300 is disposed in the housing 100 and electrically connected to the linear drive 200;

[0034] The claw fixing member 400 is provided at the front end of the housing 100. The claw fixing member 400 includes a mounting plate 410 and a connecting shaft 420 that are connected to each other and coaxially. The connecting shaft 420 passes through the fixing cylinder 110 and is connected to the free end of the drive shaft 210 so as to be circumferentially rotatable. The connecting shaft 420 and the fixing cylinder 110 form a circumferential fit. The mounting plate 410 is located outside the housing 100. At least one spiral groove 421 is spirally screwed into the peripheral wall of the connecting shaft 420. The spiral groove 421 is correspondingly provided at the position of the fixing cylinder 110.

[0035] a limiting pin 500 mounted on the fixing cylinder 110 and forming a detachable fit with the spiral groove 421 , wherein when the limiting pin 500 extends into the spiral groove 421 , a clearance fit is formed with the spiral groove 421 ;

[0036] A plurality of elastic massage claws 600 are circumferentially arranged on the mounting plate 410 , wherein the elastic massage claws 600 are arc-shaped in the length direction.

[0037] In the prior art, ordinary head massage structures have relatively simple functions, weak adaptability, and require manual control of the massage process, with weak automation.

[0038] The head massage device provided by the utility model comprises:

[0039] The front end of the housing 100 is provided with a fixing cylinder 110. The housing 100 serves as a mounting base for various components. The material of the housing 100 can be polymer or metal.

[0040] The linear drive 200 is disposed in the housing 100 and is telescopically driven by the drive shaft 210. The linear drive 200 drives the drive shaft 210 to telescopically move. A switch of the linear drive 200 can be disposed on the housing 100.

[0041] The mobile power supply 300 is disposed in the housing 100 and is electrically connected to the linear drive 200. The mobile power supply 300 provides driving voltage for the linear drive 200. The type of the mobile power supply 300 is not limited, and can be, for example, a lithium battery.

[0042] The claw fixing member 400 is disposed at the front end of the housing 100. The claw fixing member 400 includes a mounting plate 410 and a connecting shaft 420 that are interconnected and coaxial. The mounting plate 410 and the connecting shaft 420 can be integral or connected. The connecting shaft 420 passes through the fixing cylinder 110 and is connected to the free end of the drive shaft 210 for circumferential rotation. During extension and retraction, the drive shaft 210 drives the claw fixing member 400 to extend and retract, but the drive shaft 210 does not restrict the rotation of the claw fixing member 400. Specifically, the connecting shaft 420 and the drive shaft 210 can be connected longitudinally by a snap-fit ​​connection. For example, the connecting shaft 420 may be provided with an annular protrusion on its outer circumference, and the free end of the drive shaft 210 may be provided with an inwardly recessed groove, with an annular groove formed on the inner wall of the groove. The connecting shaft 420 extends into the groove to form a snap-fit ​​connection, but the annular protrusion and the annular groove have a clearance fit in cross section, allowing relative rotation between the connecting shaft 420 and the drive shaft 210. The connecting shaft 420 circumferentially mates with the fixed cylinder 110, allowing the claw fixing member 400 to maintain a defined position, allowing for flexible extension and retraction without restricting rotation. The mounting plate 410 is located outside the housing 100, and the connecting shaft 420 is provided with at least one spiral groove 421, which is screwed into the peripheral wall. The spiral groove 421 is positioned at a position corresponding to the fixed cylinder 110. The purpose of the spiral groove 421 is to allow the claw fixing member 400 to rotate during its extension and retraction.

[0043] The limiting pin 500 is mounted on the fixed cylinder 110 and forms a separable fit with the spiral groove 421. When the limiting pin 500 extends into the spiral groove 421, it forms a clearance fit with the spiral groove 421, so that the limiting pin 500 can form a fitting relationship with the spiral groove 421 while not restricting the rotation of the claw fixing member 400. Specifically, when the limiting pin 500 is separated from the spiral groove 421, the extension and contraction of the linear drive 200 causes the claw fixing member 400 to extend and contract, but does not cause the claw fixing member 400 to rotate. When the limiting pin 500 is engaged with the spiral groove 421, the extension and contraction of the linear drive 200 causes the claw fixing member 400 to extend and contract. At this time, the action of the limiting pin 500 and the spiral groove 421 drives the claw fixing member 400 to rotate.

[0044] Multiple elastic massage claws 600 are circumferentially arranged on the mounting plate 410. These claws 600 are arc-shaped along their length. Together, they form a claw-like structure, providing a foundation for head massage. The massage claws 600 perform the massage action. These claws 600 can be made of, for example, steel wire to provide a springy effect. The claws 600 can be mounted on the mounting plate 410 in a variety of ways, such as by plugging, snapping, or threading.

[0045] During operation, the extension and retraction of the linear drive 200 drives the massage elastic claw 600 to extend and retract, thereby completing the grasping and releasing massage action; if the limiting pin 500 is combined with the spiral groove 421, the extension and retraction action also causes the claw fixing part 400 to rotate, thereby having a rotating massage action.

[0046] In summary, the linear drive 200 drives the drive shaft 210 to extend and retract, and the connecting shaft 420 passes through the fixed cylinder 110 and is connected to the free end of the drive shaft 210 in a circumferentially free rotating manner. The mounting disk 410 is located outside the housing 100, and at least one spiral groove 421 is spirally screwed into the peripheral wall of the connecting shaft 420. The limiting pin 500 is installed on the fixed cylinder 110 and forms a separable fit with the spiral groove 421; the extension and retraction of the linear drive 200 drives the massage elastic claw 600 to extend and retract, thereby completing the grasping and releasing massage action; if the limiting pin 500 is combined with the spiral groove 421, the extension and retraction action also causes the claw fixing part 400 to rotate, thereby having a rotating massage action, thereby having a variety of massage modes, and achieving the purpose of relieving anxiety; the position adjustment of the massage elastic claw 600 on the mounting disk 410 makes the massage action diversified.

[0047] In one embodiment, the cross section of the spiral groove 421 is semicircular with a radius of R, and the inner end of the limiting pin 500 is hemispherical with a radius of 0.5R to 0.8R.

[0048] In this embodiment, the cross-sectional shape of the spiral groove 421 and the shape of the inner end of the limiting pin 500 are restricted, so that the limiting pin 500 and the spiral groove 421 can be matched, and the claw fixing member 400 can perform a rotational action while the smoothness of the extension and retraction action of the claw fixing member 400 is guaranteed.

[0049] In one embodiment, the mounting plate 410 is made of a polymer material, and the massage elastic claws 600 are elastically snapped onto the mounting plate 410 .

[0050] In this embodiment, a method for fixing the massage elastic claw 600 is provided. First, the mounting plate 410 is limited to a polymer material (such as rubber, etc.), and then a plurality of sockets are set on the mounting plate 410. Then, the massage elastic claw 600 can be elastically snapped into the sockets.

[0051] Reference Figure 3 In one embodiment, the mounting plate 410 is provided with a plurality of insertion holes in the circumferential direction, and the massage elastic claws 600 are inserted into the insertion holes.

[0052] In this embodiment, a simple fixing structure is provided. First, the mounting plate 410 is made of a polymer material, which provides a basis for elastic plug-in. Then, a plurality of sockets are provided on the mounting plate 410 so that the massage elastic claws 600 can be conveniently plugged in and out of the mounting plate 410.

[0053] Reference Figure 3 In one embodiment, the claw fixing member 400 is an integrally formed structure.

[0054] In this embodiment, the structure of the claw fixing member 400 is simplified, which improves efficiency and reliability.

[0055] In one embodiment, the mobile power supply 300 is rechargeable.

[0056] In this embodiment, the mobile power supply 300 is configured to be rechargeable, so that the use process of the head massage device is more convenient. Preferably, the interface of the mobile power supply 300 is of type-c type to improve adaptability.

[0057] Reference Figures 1 to 4 In one embodiment, the massage elastic claw 600 is detachably mounted on the mounting plate 410 .

[0058] In this embodiment, the massage elastic claw 600 is detachably provided, which provides a basis for improving the flexibility of use. The massage elastic claw 600 can be connected to the mounting plate 410 in various ways, such as screw connection or clamping.

[0059] Reference Figures 1 to 4 In one embodiment, the number of the massage elastic claws 600 is six, and they are evenly arranged around the mounting plate 410.

[0060] In this embodiment, the number of the massage elastic claws 600 is limited to meet the adaptability requirements in various scenarios.

[0061] In one embodiment, the massage elastic claw 600 includes a steel wire and a rubber head connected to the free end of the steel wire.

[0062] In this embodiment, the structure of the massage elastic claw 600 is restricted, the structural elasticity is achieved by the steel wire, and the flexibility effect is achieved by the rubber head to avoid damaging the scalp.

[0063] In one embodiment, the limiting pin 500 and the fixing cylinder 110 are threadedly connected.

[0064] In this embodiment, an internal thread structure is provided on the fixing cylinder 110 corresponding to the limiting pin 500, and an external thread is provided on the outer periphery of the limiting pin 500, so that a threaded fit is formed between the limiting pin 500 and the fixing cylinder 110, and the adjustment process of the limiting pin 500 is smoother.

[0065] In summary, in the head massage device provided by the present invention, the linear drive 200 drives the drive shaft 210 to complete the telescopic drive, the connecting shaft 420 passes through the fixed cylinder 110 and is connected to the free end of the drive shaft 210 in a circumferentially free rotating manner, the mounting disk 410 is located outside the casing 100, and at least one spiral groove 421 is spirally screwed into the peripheral wall of the connecting shaft 420, and the limiting pin 500 is installed on the fixed cylinder 110 and forms a separable fit with the spiral groove 421; the telescopic movement of the linear drive 200 drives the massage elastic claw 600 to telescope, thereby completing the grasping and releasing massage action; if the limiting pin 500 is combined with the spiral groove 421, the telescopic action also causes the claw fixing part 400 to rotate, thereby having a rotating massage action, thereby having a variety of massage modes, and achieving the purpose of relieving anxiety; the position adjustment of the massage elastic claw 600 on the mounting disk 410 makes the massage action diversified.
