Description

Technical Field

[0001] The present invention relates to the field of massagers, and particularly refers to a microcurrent head massager.

Background Art

[0002] With the accelerating pace of study, work, and life, people are increasingly feeling pressure, and their bodies often fall into a state of fatigue. Therefore, for fatigue recovery, many people adopt massages, especially head massagers, to relieve head fatigue. However, since the cost of manual massagers is high and the consumption time is inconvenient, electric head massagers with low cost and convenient use are well-received by people. Conventional head massagers achieve the massage of the user's head by means of mechanical kneading. For example, Patent Document 1 discloses a torsion arm type head massager, and the soft massage heads of at least three torsion massage units in the head massager are twisted synchronously, achieving the effect of simulating kneading by fingers during the process of the soft massage heads approaching and separating from each other, and having a better massage experience. However, the above head massager only has a mechanical massage method, and the massage function is single, and cannot meet the diverse usage needs of users. Therefore, in recent years, head massagers with microcurrent massage functions have emerged. For example, Patent Document 1 discloses a microcurrent scalp massager, which includes a driving device, a gear group, a circuit board, a fixed base, and a massage device. The driving device and the massage device are respectively provided on both sides of the fixed base and are electrically connected to the circuit board. The driving device is gear-connected to the massage device by the gear group. The massage device is provided in the massage device and includes a conductive column electrically connected to the circuit board and a massage means capable of transmitting microcurrent to the human body. The conductive column abuts against the massage means, and the driving device drives the massage device to drive the massage means to perform circular motion along the central axis. However, since the conductive and transmission structure of the microcurrent scalp massager is complex, the overall structure is complex and the cost is high.

[0003] Therefore, in order to solve the above problems, it is necessary to provide a technical solution.

Modes for Carrying Out the Invention

[0017] For the sake of easier understanding by those skilled in the art, the present invention will be further described below by combining examples and drawings. The content mentioned in the embodiments does not limit the present invention.

[0018] As shown in FIGS. 1 to 8, the present invention provides a microcurrent head massager, which includes an external housing 1, a control circuit board 2, a drive mechanism 3, a conductive transmission mechanism, and a conductive massage head mechanism 5. The external housing 1 includes an upper external housing 16 and a lower external housing 17. The upper external housing 16 and the lower external housing 17 are removably connected by a screw member. An accommodation cavity is formed inside the external housing 1. Both the control circuit board 2 and the drive mechanism 3 are provided in the accommodation cavity. The drive mechanism 3 includes a drive motor 31 electrically connected to the control circuit board 2. The conductive transmission mechanism includes several torsion drive gears 41 connected to transmit to the drive mechanism 3. Each of the torsion drive gears 41 is provided with a conductive shaft 42. Each of the conductive shafts 42 is electrically connected to the control circuit board 2. And one end of each of the conductive shafts 42 away from the control circuit board 2 extends outside the external housing 1, and a conductive shaft sleeve 43 is externally fitted. The conductive massage head mechanism 5 includes an insulating film sleeve 51 and several conductive massage heads 52 provided on the insulating film sleeve 51. The insulating film sleeve 51 is connected to the bottom of the external housing 1. Each of the conductive shaft sleeves 43 is inserted into one of the conductive massage heads 52 respectively. Specifically, the number of the torsion drive gears 41, the conductive shafts 42, the conductive shaft sleeves 43, and the conductive massage heads 52 is from 3 to 8.

[0019] In this embodiment, the drive mechanism 3 rotates several torsion drive gears 41. The torsion drive gears 41 rotate the conductive shaft 42, and the conductive shaft 42 twists the conductive shaft sleeve 43 and the conductive massage head 52, thereby realizing mechanical kneading massage on the user's head. Through the conductive connection between the control circuit board 2, the conductive shaft 42, the conductive shaft sleeve 43, and the conductive massage head 52, while performing mechanical kneading massage, the conductive massage head 52 conducts a microcurrent to the head to perform microcurrent massage on the head, increasing the types of massage functions. Also, in this embodiment, the torsion drive gears 41, the conductive shaft 42, and the conductive shaft sleeve 43 can achieve conduction and transmission, and compared with the conductive and transmission structures in the prior art, the structure is simpler and the cost is lower.

[0020] Furthermore, as shown in FIGS. 7-8, the conductive shaft 42 includes a first shaft 421 and a second shaft 422 that are connected to each other. The first shaft 421 and the second shaft 422 are provided at an included angle. The first shaft 421 is inserted into the torsion drive gear 41, and the conductive shaft sleeve 43 is movably externally fitted on the outside of the second shaft 422. Specifically, the first shaft 421 and the second shaft 422 are arranged to be 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. By making the transmission block 423 substantially rectangular, the torsion drive gear 41 rotates the conductive shaft 42 synchronously. A locking block 424 is provided on the second shaft 422, and a clip 431 is provided on the conductive shaft sleeve 43. The clip 431 is locked to the locking block 424, whereby the conductive shaft sleeve 43 is movably externally fitted on the outside of the second shaft 422. In this embodiment, the first shaft 421 and the second shaft 422 are provided at an included angle, and the conductive shaft sleeve 43 is movably externally fitted on the outside of the second shaft 422, thereby converting the rotational motion of the torsion drive gear 41 into the twisting motion of the conductive massage head 52 to realize the kneading massage of the head.

[0021] Furthermore, as shown in FIGS. 5 to 7, the conductive and transmission mechanism further includes several conductive springs 45. One end of each of the conductive springs 45 is electrically connected to the control circuit board 2, and the other end of each is electrically connected to one end of the conductive shaft 42 respectively. In this embodiment, since the conductive spring 45 can perform telescopic movement, by arranging the conductive spring 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 even during the movement process.

[0022] Furthermore, as shown in FIGS. 3 to 7, the conductive and transmission mechanism further includes an internal housing 46. The internal housing 46 includes an upper internal housing 461 and a lower internal housing 462 that are removably connected. The internal housing 46 is fixedly connected inside the external housing 1. Several of the torsion drive gears 41 and several of the first shafts 421 are provided inside the internal housing 46. Several of the second shafts 422 all extend outside the internal housing 46. Several hollow guide columns 461 are provided at the tip of the internal housing 46. Each of the conductive springs 45 is provided on one of the hollow guide columns 461 respectively. One end of each of the first shafts 421, away from the second shaft 422, extends to one of the hollow guide columns 461 respectively and is electrically connected to the conductive spring 45. One end of each of the conductive springs 45, away from the conductive shaft 42, extends outside the hollow guide column 461 and is electrically connected to the control circuit board 2. In this embodiment, by arranging the internal housing 46, the components in the conductive and transmission mechanism can be provided in the internal housing 46, and the arrangement of the components in the conductive and transmission mechanism becomes more reasonable. By arranging the hollow guide column 461 and restricting the connection position between the conductive spring 45 and the conductive shaft 42 to the hollow guide column 461, the separation between the conductive shaft 42 and the conductive spring 45 is prevented during the movement process, ensuring that the electrical connection between the conductive spring 45 and the conductive shaft 42 is more stable and reliable.

[0023] Furthermore, as shown in FIGS. 4 to 7, the conductive and transmission mechanism further includes several insulating protection sleeves 47, each of the insulating protection sleeves 47 is connected to the bottom end of the inner housing 46, and each of the second shafts 422 and the conductive shaft sleeve 43 outside thereof is provided so as to pass through one of the insulating protection sleeves 47. A locking groove 432 connected to the insulating protection sleeve 47 is provided on the outer peripheral side of the conductive shaft sleeve 43. Preferably, both the conductive massage head 52 and the insulating protection sleeve 47 are made of a soft material. In this embodiment, by arranging the soft insulating protection sleeve 47, foreign matters such as dust and water are prevented from entering the inside of the inner housing 46, and the service life is extended.

[0024] Furthermore, as shown in FIG. 6, the drive mechanism 3 is provided in the inner housing 46 and further includes a transmission gear group 32. The output shaft of the drive motor 31 is connected to be transmitted to the transmission gear group 32, and the transmission gear group 32 is connected to be transmitted to several of the torsion drive gears 41 through the inner housing 46. Specifically, the transmission gear group 32 includes a first gear 321 fixedly connected to the output shaft of the drive motor 31, a second gear means 322 connected to be transmitted to the first gear 321, a third gear means 323 connected to be transmitted to the second gear means 322, and a fourth gear means 324 connected to be transmitted to the third gear means 323. One of the torsion drive gears 41 is connected to be transmitted to the fourth gear means 324, and several of the torsion drive gears 41 are connected to be transmitted to each other. In this embodiment, after reducing the rotation speed of the drive motor 31 by the transmission gear group 32, it is connected to the torsion drive gear 41.

[0025] Furthermore, as shown in FIGS. 3 to 4, the massager further includes a rechargeable battery 10 electrically connected to the control circuit board 2. A grip 11 is formed on the top portion of the external housing 1, and a charging contact 12 and a control button 13 are provided on the grip 11. Both the charging contact 12 and the control button 13 are electrically connected to the control circuit board 2 respectively. During charging, the grip is placed on an external charging station and charges the rechargeable battery 10 via the charging contact 12, which is a prior art and will not be elaborated here.

[0026] Furthermore, as shown in FIGS. 3 and 5, the massager further includes a light therapy mechanism 6. The light therapy mechanism 6 is provided in the accommodation cavity and includes a lamp panel 61 and several lamp beads 62 provided on the lamp panel 61. The lamp panel 61 is electrically connected to the control circuit board 2. A first light transmission hole 15 and a second light transmission hole 511 are respectively provided at positions of the bottom of the external housing 1 and the insulating film sleeve 51 corresponding to the light therapy mechanism 6. Specifically, the light therapy mechanism 6 further includes a light transmission protection case 63. The light transmission protection case 63 is provided to cover the outside of the lamp beads 62 and is inserted into the first light transmission hole 15 and the second light transmission hole 511. Specifically, by controlling the magnitude of the wavelength of the light of the lamp beads 62, light therapy effects in modes such as red light, blue light, and purple light are exerted on the user. In this embodiment, by arranging the light therapy mechanism 6, kneading massage and microcurrent massage can be performed on the user's head, and at the same time, the light therapy effect can be exerted, making the functions of the massager more diverse and meeting the needs of the user.
