Description

Technical Field

[0001] This application relates to health care and physiotherapy devices, and more particularly to a head massage device. Background Art

[0002] With the rapid development of social economy, people's life rhythm is getting faster and faster, and the work pressure is getting greater and greater, resulting in people often feeling physically and mentally exhausted. Lack of exercise for a long time brings various sub-health problems such as headaches, shoulder and neck soreness, and knee discomfort. Therefore, various massagers, especially head massagers, are very popular. With the squeezing, rolling, vibrating, kneading and other massage actions of the massager, discomfort can be relieved and the mood can be soothed.

[0003] In order to make the head massager more similar to the effect of human hands, there are also massagers on the market that can imitate the pinching massage of human hands. For example, the Chinese utility model patent with the application number 202221542226.0 and the publication number CN218500974U discloses a head massager that imitates the massage of human hands. In the internal space formed by assembling the front shell and the bottom shell, there is a driving mechanism that drives a swing arm rotatably installed relative to the bottom shell and extending out of the action hole at the bottom of the bottom shell to swing back and forth, thereby driving the swing arm silicone installed at the end of the swing arm to reciprocally comb. The multi-point contacts at the end of the silicone brush achieve combing and pinching, and can imitate the pinching massage of the human hand on the head. Specifically, the driving mechanism is realized by a cam, multiple sliders and a slider push rod. There is a guide groove under the cam, and multiple sliders are installed in the guide groove through slider bumps and can only slide radially. The slider push rod is rotatably connected to the slider through a rotating shaft, and the slider push rod is rotatably connected to the swing arm through a rotating shaft. The rotation of the cam drives the sliders to reciprocate radially, pushing the slider push rod to rotate and then driving the swing arm to swing back and forth, realizing reciprocating combing and pinching. Although this head massager realizes the imitation of human hand massage, the driving method of driving multiple sliders to reciprocate radially by the rotation of a single cam is prone to jamming during actual massage use, resulting in poor user experience.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. Moreover, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0032] Figure 1 The external structure of a head massage device 100 according to an embodiment of the present application is shown, Figure 2 and Figure 3 respectively show internal structure cross-sectional views of the head massage device 100 in a state where the massage claws are open and a state where the massage claws are closed. Refer to Figures 1 to 3 As shown, the head massage device 100 mainly includes a housing 10, a driving mechanism 20 and a plurality of massage claws 30. The driving mechanism 20 is disposed inside the housing 10. Four massage claws 30 are rotatably mounted inside the housing 10 and extend out from the bottom of the housing 10, and are driven by the driving mechanism 20 to rotate outward to open and rotate inward to close, thereby realizing a hand-like pinching massage.

[0033] Specifically refer to Figure 2As shown, the housing 10 further includes an upper housing 11, a lower housing 12, a partition housing 13 and a mounting base 14. The upper housing 11 and the lower housing 12 are combined with each other by a connection means such as snap-fastening to form an internal space, and the partition housing 13 and the mounting base 14 further divide the internal space into an upper space, a middle space and a lower space. The mounting base 14 is disposed inside the lower housing 12, and the respective components of the driving mechanism 20 are respectively supported and mounted on the partition housing 13 and the mounting base 14. Refer to Figure 2 Combined Figure 4 As shown, the driving mechanism 20 includes a driving motor 21, a worm 22, a turbine 23, a transmission gear set 24, four driving gears 25 and four sliders 26. The driving motor 21 is horizontally mounted on one side of the upper part of the partition housing 13, the worm 22 is fixedly connected coaxially with the driving motor 21, the turbine 23, the transmission gear set 24 and the four driving gears 25 are respectively vertically rotatably supported between the partition housing 13 and the mounting base 14, the turbine 23 meshes with the worm 22, the input gear 241 of the transmission gear set 24 meshes with the turbine 23, the output gear 242 of the transmission gear set 24 is disposed in the middle of the mounting base 14, and the four driving gears 25 are evenly spaced around the output gear 242 and respectively mesh with the output gear 242. Thus, the driving motor 21 drives the worm 22 to rotate, and then drives the four driving gears 25 to rotate synchronously through the turbine 23 and the transmission gear set 24. Refer to again Figure 2 Combined Figure 4 And Figure 5 As shown, four radially extending chutes 15 are formed in the upper part of the mounting base 14 opposite to the four driving gears 25, the four chutes 15 are distributed in a cross shape, and the four sliders 26 are respectively slidably mounted in the chutes 15 below the four driving gears 25. Moreover, a circumferential guide groove 251 with an eccentric setting is formed at the bottom of each driving gear 25, and a first guide post 261 and a second guide post 262 are protruded at intervals along the sliding direction at the top of each slider 26, and the first guide post 261 and the second guide post 262 are respectively inserted into opposite ends in the circumferential guide groove 251 at the bottom of the driving gear 25, so that when the driving gear 25 rotates, the slider 26 can be reciprocally moved along the chute 15 through the circumferential guide groove 251 acting on the first guide post 261 and the second guide post 262, thereby driving the massage claws 30 rotatably connected to the slider 26 to reciprocally open ( Figure 2 As shown) Figure 3 and close (

[0034] Specifically refer to Figure 2 And Figure 4As shown, each massage claw 30 is further composed of a swing arm 31 and a silica gel claw head 32. Four first mounting holes 16 that penetrate to the upper part are provided in the lower part of the mounting seat 14. The lower shell 12 also has four second mounting holes 121 that penetrate inside and outside and are opposite to the four first mounting holes 16 for the massage claws 30 to extend out. A first rotating shaft 311 is provided in the middle of the swing arm 31 of each massage claw 30 and is rotatably mounted in the first mounting hole 16. For example, both ends of the first rotating shaft 311 can be rotatably supported in the rotating shaft holes correspondingly opened on both sides of the first mounting hole 16 so as to be rotatable in the first mounting hole 16. A second rotating shaft 312 is provided at the inner end of the swing arm 31 and is snapped into the downwardly open card slot 263 provided at the bottom of the slider 26 to be rotatably connected to the slider 26. In this way, the reciprocating movement of the slider 26 along the chute 15 can drive the swing arm 31 to rotate around the axis of the first rotating shaft 311. The silica gel claw head 32 is mounted at the outer end of the swing arm 31 that extends out of the first mounting hole 16 and the second mounting hole 121. For details, see Figure 2 As shown, a clamping arm 313 extends from the outer end of the swing arm 31, and the silica gel claw head 32 is clamped on the clamping arm 313 to swing reciprocally together with the rotation of the swing arm 31. A plurality of massage teeth 322 are provided on the silica gel claw head 32, and during the opening and closing process of the silica gel claw head 32 swinging reciprocally with the swing arm 31, it can simulate the pinching massage of the human hand.

[0035] Further referring to Figure 1 and Figure 2 As shown, according to the above embodiments of the present application, the head massage device 100 also has a control main board 41 and a battery 42 provided in the upper part of the partitioned housing 13 inside the upper housing 11. The control main board 41 is electrically connected to the drive motor 21 and the battery 42 respectively to supply power to the drive motor 21 and control the operation of the drive motor 21. A control button 43 is also provided on the upper housing 11 and is electrically connected to the control main board 41 to control the head massage device 100.

The charged components such as the control circuit board 41, the battery 42, and the drive motor 21 are mainly distributed in the upper space, and the mechanical transmission components such as the transmission gear set 24, the four drive gears 25, and the four sliders 26 are mainly distributed in the middle space between the partitioned housing 13 and the mounting seat 14, and the four massage claws 30 are distributed in the lower space to avoid interference with each other.

[0036] According to the head massage device 100 of the above embodiment of the present application, the driving motor 21 drives the worm 22 to rotate, and then drives the four driving gears 25 to rotate synchronously through the turbine 23 and the transmission gear set 24. The guiding grooves 251 eccentrically arranged at the bottom of the four synchronously rotating driving gears 25 act on the first guiding posts 261 and the second guiding posts 262 protruding from the tops of the four sliders 26, driving the four sliders 26 to reciprocate along the sliding grooves 15 as the driving gears 25 rotate, thereby driving the four massage claws 30 to simultaneously close inward or open outward, realizing the imitation of human hand pinching massage. When the slider 26 slides to the inner side along the sliding groove 15, as shown in Figure 2 shown, the slider 26 drives the swing arm 31 of the massage claw 30 to rotate counterclockwise around the axis of the first rotating shaft 311, so that the silica gel claw head 32 at the outer end of the swing arm 31 opens outward synchronously. When the slider 26 slides to the outer side along the sliding groove 15, as shown in Figure 3 shown, the slider 26 drives the swing arm 31 of the massage claw 30 to rotate clockwise around the axis of the first rotating shaft 311, so that the silica gel claw head 32 at the outer end of the swing arm 31 closes inward synchronously. The pinching action of the head massage device 100 according to the above embodiment of the present application is smooth and not prone to jamming, the pinching force is uniform, and the user's comfort is improved. The head massage device 100 according to the above embodiment of the present application can not only be used alone for pinching massage of the head, shoulder and neck, and joint parts, but also be integrated as a massage component in various massage apparatuses.

[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
