Description

Technical Field

[0001] This utility model relates to the field of massage devices, and in particular to a microcurrent head massager. Background Technology

[0002] With the ever-increasing pace of study, work, and life, people are experiencing greater stress and often feel fatigued. Therefore, many people resort to massage to alleviate fatigue, especially head massagers. However, manual massage is expensive and inconvenient, making low-cost and easy-to-use electric head massagers increasingly popular. Existing head massagers achieve their effect through mechanical kneading. For example, Chinese utility model patent CN215584779U discloses a twisting arm head massager, in which at least three twisting massage units with soft massage heads rotate synchronously. The movement of the soft massage heads closer and further apart simulates the kneading effect of fingers, providing a better massage experience. However, the aforementioned head massagers only offer mechanical massage, with limited functionality, failing to meet the diverse needs of users. Therefore, in recent years, head massagers with microcurrent massage functions have emerged, such as Chinese utility model patent CN213788703U, which discloses a microcurrent scalp massager, including a drive device, a gear set, a circuit board, a fixed base, and a massage device. The drive device and the massage device are respectively set on both sides of the fixed base and electrically connected to the circuit board. The drive device is connected to the massage device gears through the gear set. The massage device includes a conductive column set inside the massage device and electrically connected to the circuit board, and a massage component that can transmit microcurrent to the human body. The conductive column abuts against the massage component. The drive device drives the massage device and causes the massage component to move in a circular motion along the central axis. However, the conductive and transmission structure of this microcurrent scalp massager is relatively complex, resulting in a complex overall structure and high cost.

[0003] Therefore, it is necessary to provide a technical solution to address the above problems. Utility Model Content

Detailed Implementation

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0035] like Figures 1 to 8As shown, this utility model provides a microcurrent head massager, which includes a housing 1, a control circuit board 2, a drive mechanism 3, a conductive transmission mechanism, and a conductive massage head mechanism 5. The housing 1 includes an upper housing 16 and a lower housing 17, which are detachably connected by a threaded component. The interior of the housing 1 forms an accommodating cavity. The control circuit board 2 and the drive mechanism 3 are both disposed in the accommodating cavity. The drive mechanism 3 includes a drive motor 31, which is electrically connected to the control circuit board 2. The conductive transmission mechanism includes several components connected to the drive motor. The transmission mechanism 3 includes a torsion drive gear 41, each of which is equipped with a conductive shaft 42. Each conductive shaft 42 is electrically connected to the control circuit board 2, and one end of each conductive shaft 42, away from the control circuit board 2, extends to the outside of the outer casing 1 and is fitted with a conductive shaft sleeve 43. The conductive massage head mechanism 5 includes an insulating film sleeve 51 and a plurality of conductive massage heads 52 disposed on the insulating film sleeve 51. The insulating film sleeve 51 is connected to the bottom of the outer casing 1, and each conductive shaft sleeve 43 is inserted into a conductive massage head 52. Specifically, the number of the torsion drive gear 41, the conductive shaft 42, the conductive shaft sleeve 43, and the conductive massage head 52 is 3-8.

[0036] In this embodiment, the drive mechanism 3 drives several torsion drive gears 41 to rotate, which in turn drives the conductive shaft 42 to rotate. The conductive shaft 42 then drives the conductive bushing 43 and the conductive massage head 52 to twist, thereby achieving a mechanical kneading massage on the user's head. Furthermore, through the conductive connection between the control circuit board 2, the conductive shaft 42, the conductive bushing 43, and the conductive massage head 52, while performing the mechanical kneading massage, the conductive massage head 52 conducts a microcurrent to the head, providing a microcurrent massage and increasing the variety of massage functions. Moreover, in this embodiment, conductivity and transmission can be achieved simply by rotating the torsion drive gears 41, the conductive shaft 42, and the conductive bushing 43, resulting in a simpler and lower-cost structure compared to existing conductive and transmission structures.

[0037] Furthermore, such as Figure 7-8As shown, the conductive shaft 42 includes a first shaft 421 and a second shaft 422 connected to each other, with the first shaft 421 and the second shaft 422 arranged at an angle. The first shaft 421 is inserted into the torsion drive gear 41, and the conductive shaft sleeve 43 is movably sleeved on the outside of the second shaft 422. Specifically, the first shaft 421 and the second shaft 422 are integrally formed. A transmission block 423 is provided on the first shaft 421, and the transmission block 423 is inserted into the torsion drive gear 41. The transmission block 423 is approximately cuboid in shape to facilitate the torsion drive gear 41 to drive the conductive shaft 42 to rotate synchronously. A locking block 424 is provided on the second shaft 422, and a clamp 431 is provided on the conductive shaft sleeve 43. The clamp 431 engages with the locking block 424 to allow the conductive shaft sleeve 43 to be movably sleeved on the outside of the second shaft 422. In this embodiment, the first shaft 421 and the second shaft 422 are set at an angle, and the conductive bushing 43 is movably sleeved on the outside of the second shaft 422, so as to convert the rotational motion of the torsion drive gear 41 into the torsion motion of the conductive massage head 52, thereby realizing the kneading massage of the head.

[0038] Furthermore, such as Figure 5-7 As shown, the conductive transmission mechanism also includes several conductive springs 45. One end of each conductive spring 45 is electrically connected to the control circuit board 2, and the other end is electrically connected to one end of a conductive shaft 42. In this embodiment, since the conductive springs 45 can extend and retract, by setting the conductive springs 45 between the control circuit board 2 and one end of the conductive shaft 42, a reliable electrical connection between the conductive shaft 42 and the control circuit board 2 can be maintained during the movement of the conductive shaft 42.

[0039] Furthermore, such as Figure 3-7As shown, the conductive transmission mechanism further includes an inner housing 46, which includes a detachably connected upper inner housing 461 and a lower inner housing 462. The inner housing 46 is fixedly connected to the interior of the outer housing 1. A plurality of torsion drive gears 41 and a plurality of first shafts 421 are disposed inside the inner housing 46, and a plurality of second shafts 422 extend to the outside of the inner housing 46. A plurality of hollow guide posts 461 are disposed at the top of the inner housing 46. Each conductive spring 45 is disposed in one of the hollow guide posts 461. One end of each first shaft 421 away from the second shaft 422 extends into one of the hollow guide posts 461 and is electrically connected to the conductive spring 45. One end of each conductive spring 45 away from the conductive shaft 42 extends to the outside of the hollow guide post 461 and is electrically connected to the control circuit board 2. In this embodiment, by providing an inner housing 46, the components in the conductive transmission mechanism can be housed within the inner housing 46, thereby making the arrangement of the components in the conductive transmission mechanism more reasonable. Furthermore, by providing a hollow guide post 461, the connection position between the conductive spring 45 and the conductive shaft 42 is restricted within the hollow guide post 461, preventing the conductive shaft 42 from separating from the conductive spring 45 during movement, thus ensuring a more stable and reliable electrical connection between the conductive spring 45 and the conductive shaft 42.

[0040] Furthermore, such as Figure 4-7 As shown, the conductive transmission mechanism further includes several insulating protective sleeves 47. Each insulating protective sleeve 47 is connected to the bottom end of the inner housing 46. Each second shaft 422 and its outer conductive bushing 43 pass through an insulating protective sleeve 47. The outer periphery of the conductive bushing 43 is provided with a slot 432 for connection with the insulating protective sleeve 47. Preferably, both the conductive massage head 52 and the insulating protective sleeve 47 are made of soft material. In this embodiment, by providing soft insulating protective sleeves 47, dust, water, and other foreign objects can be prevented from entering the interior of the inner housing 46, extending its service life.

[0041] Furthermore, such as Figure 6As shown, the drive mechanism 3 is mounted on the inner housing 46. The drive mechanism 3 also includes a transmission gear set 32. The output shaft of the drive motor 31 is driven by the transmission gear set 32. The transmission gear set 32 ​​passes through the inner housing 46 and is driven by a plurality of torsional drive gears 41. Specifically, the transmission gear set 32 ​​includes a first gear 321 fixedly connected to the output shaft of the drive motor 31, a second gear assembly 322 driven by the first gear 321, a third gear assembly 323 driven by the second gear assembly 322, and a fourth gear assembly 324 driven by the third gear assembly 323. One of the torsional drive gears 41 is driven by the fourth gear assembly 324, and the plurality of torsional drive gears 41 are driven by each other. In this embodiment, the drive motor 31 is decelerated by the transmission gear set 32 ​​before being connected to the torsional drive gears 41.

[0042] Furthermore, such as Figure 3-4 As shown, the massager also includes a rechargeable battery 10, which is electrically connected to the control circuit board 2. A handle 11 is formed on the top of the outer casing 1, and the handle 11 is provided with charging contacts 12 and control buttons 13. Both the charging contacts 12 and the control buttons 13 are electrically connected to the control circuit board 2. During charging, the handle is placed in the external charging dock, and the rechargeable battery 10 is charged through the charging contacts 12. This is existing technology and will not be described in detail here.

[0043] Furthermore, such as Figure 3 , 5 As shown, the massager also includes a phototherapy mechanism 6, which is disposed within the accommodating cavity. The phototherapy mechanism 6 includes a lamp board 61 and several lamp beads 62 disposed on the lamp board 61. The lamp board 61 is electrically connected to the control circuit board 2. The bottom of the outer shell 1 and the insulating film sleeve 51 are respectively provided with a first light-transmitting hole 15 and a second light-transmitting hole 511 at positions corresponding to the phototherapy mechanism 6. Specifically, the phototherapy mechanism 6 also includes a light-transmitting protective shell 63, which covers the outside of the lamp beads 62 and is inserted into the first light-transmitting hole 15 and the second light-transmitting hole 511. Specifically, by controlling the wavelength of the light from the lamp beads 62, phototherapy effects such as red light, blue light, and purple light can be achieved for the user. In this embodiment, by providing the phototherapy mechanism 6, phototherapy effects can be performed simultaneously with kneading massage and microcurrent massage on the user's head, making the massager more versatile and meeting the user's needs.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
