Description

Technical Field

[0001] The present application relates to health care and physiotherapy equipment, and more specifically, to a massage device. Background Art

[0002] With the rapid development of social economy, people's pace of life is getting faster and faster, and the work pressure is getting greater and greater, which leads to people often feeling physically and mentally exhausted. Long-term lack of exercise leads to various sub-health problems such as headaches, shoulder and neck pain, knee joint discomfort, etc. Therefore, various massagers are very popular. With the help of massage movements such as squeezing, rolling, vibrating, kneading, etc., the discomfort can be relieved and the mood can be soothed.

[0003] In order to make the massage more similar to the effect of human hands, massagers that can imitate human hand grasping and kneading massage are now available on the market. For example, the Chinese utility model patent with application number 202221542226.0 and announcement number CN218500974U discloses a head massager that imitates human hand massage. In the internal space assembled by the face shell and the bottom shell, a driving mechanism is provided to drive the swing arm that extends from the action hole at the bottom of the bottom shell and is rotatably installed relative to the bottom shell to swing back and forth, thereby driving the swing arm silicone reciprocating grasping comb that is mounted at the end of the swing arm. The multi-pointed contacts at the end of the silicone brush realize combing and grasping, which can imitate human hand grasping and kneading massage of the head. Specifically, the driving mechanism is realized by a cam, a slider and a slider push rod. A guide groove is provided below the cam. The slider is installed in the guide groove through the slider bump and can only slide radially. The slider push rod is relatively rotatably connected to the slider through a rotating shaft. The slider push rod is relatively rotatably connected to the swing arm through a rotating shaft. The cam rotates to drive the slider to reciprocate radially, and the slider push rod is driven to rotate and then drive the swing arm to swing back and forth, realizing reciprocating combing and grasping. Although this head massager can simulate human hand massage, the driving method of the slider to slide radially and reciprocatingly by the rotation of the cam is prone to jamming during actual massage use, resulting in a poor user experience.

[0038] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with 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 intended to limit the present application. In addition, the embodiments in the present application and the features in the embodiments may be combined with each other in the absence of conflict.

[0039] See also Figure 1 and Figure 2 As shown, a massage device 100 according to an embodiment of the present application is mainly composed of a housing 10, a driving mechanism 20 and a plurality of massage claws 30. The driving mechanism 20 is disposed in the housing 10. The plurality of massage claws 30 are rotatably installed in the housing 10 and extend from the bottom of the housing 10. They are driven by the driving mechanism 20 to rotate outward to open and rotate inward to close, thereby realizing a massage imitating human hand grasping and kneading.

[0040] See Figure 2 As shown, the housing 10 is further composed of an upper shell 11, a lower shell 12 and a partition shell 13. The upper shell 11 and the lower shell 12 are connected to each other by a connection method such as a buckle to form an internal space. The partition shell 13 further divides the internal space into an upper space and a lower space. Figure 2 Combination Figure 3 As shown, the driving mechanism 20 further includes a driving motor 21, a worm 22, a turbine 23, a transmission gear set 24, a driving wheel 25 and a plurality of push blocks 28. The worm 22 is coaxially fixedly connected with the output shaft 211 of the driving motor 21, the turbine 23 is meshed with the worm 22, the input gear 241 of the transmission gear set 24 is meshed with the turbine 23, and the output gear 242 of the transmission gear set 24 is coaxially fixedly connected with the driving wheel 25. The driving wheel 25 forms a circle of wave-shaped guide grooves 26 around the periphery, and a plurality of push blocks 28 are arranged around the periphery of the driving wheel 25 in a manner of sliding only up and down, and each push block 28 is provided with a guide rod 282 inserted into the circle of wave-shaped guide grooves 26. In this way, when the driving motor 21 is working, it can drive the worm 22 to rotate, and then drive the driving wheel 25 to rotate through the turbine 23 and the transmission gear set 24. The rotation of the driving wheel 25 can drive each push block 28 to move up and down along a circle of wave-shaped guide grooves 26, thereby driving the massage claws 30 connected to the push block 28 for relative rotation to open and close reciprocally.

[0041] Figure 2 and Figure 3 In the illustrated embodiment, the worm 22, the worm gear 23 and the transmission gear set 24 constitute a transmission assembly that is transmission-connected between the drive motor 21 and the drive wheel 25, and is used to transmit the rotation of the drive motor 21 to the drive wheel 25 and thereby achieve a speed regulation effect. However, according to different embodiments of the present application, it is obvious to those skilled in the art that the specific implementation of the transmission assembly is not limited to the illustrated embodiment, and various existing suitable transmission means may also be used. Figure 2 As shown, in order to make the internal structure of the entire massage device 100 compact and small, the drive motor 21 and the transmission assembly are mainly distributed in the upper space, and the drive wheel 25, the push block 28 and the massage claw 30 are distributed in the lower space to avoid interference with each other.

[0042] According to a specific embodiment of the present application, see Figure 4 and Figure 5 As shown, the driving wheel 25 further includes an upper rotating wheel 251 and a lower rotating wheel 252. The upper rotating wheel 251 is integrally formed with the output gear 242, and the lower end of the upper rotating wheel 251 has a circle of wavy lower end surface 2511, and a square column 2512 is provided in the center. The lower rotating wheel 252 has a circle of wavy upper end surface 2522 opposite to the circle of wavy lower end surface 2511 of the upper rotating wheel 251, and the upper end of the lower rotating wheel 252 is also coaxially provided with a cylinder 2522 and a square hole 2523 is provided in the center of the cylinder 2522. The upper rotating wheel 251 and the lower rotating wheel 252 are inserted and assembled so that the square column 2512 is inserted into the square hole 2523 of the lower rotating wheel 252 and the round column 2522 is inserted into the upper rotating wheel 251, so that the upper rotating wheel 251 and the lower rotating wheel 252 can be coaxially fixedly connected and rotated together with the output gear 242, and a circle of wavy lower end surface 2511 of the upper rotating wheel 251 and a circle of wavy upper end surface 2521 of the lower rotating wheel 252 form a circle of wavy guide grooves 26. In addition, the output gear 242, the upper rotating wheel 251 and the lower rotating wheel 252 are correspondingly provided with shaft holes 29 that pass through from top to bottom, and are supported and installed between the partition shell 13 and the lower shell 12 through the installation shaft 27 (see Figure 2 As shown), the three can rotate around the mounting axis 27 at the same time. Figure 4 and Figure 5 As shown, each push block 28 has an arc-shaped inner side surface 281 that fits with the outer peripheral surface of the driving wheel 25 and is arranged around the outer periphery of the driving wheel 25. The guide rod 282 protrudes from the inner side surface 281 of the push block 28 and is inserted into a circle of wavy guide grooves 26 of the driving wheel 25. In this way, the push block 28 can reciprocate up and down along the circle of wavy guide grooves 26 as the driving wheel 25 rotates more smoothly. Figure 4 and Figure 5 In the specific embodiment shown, the circle of wavy guide grooves 26 is composed of a plurality of smoothly connected wave periods of the same wave, and the guide rods 282 of the plurality of push blocks 28 are respectively slidably inserted in the same position within a wave period, driving the plurality of massage claws 30 to open or close synchronously with the same amplitude. According to different embodiments of the present application, the wave form of the circle of wavy guide grooves 26 is not limited to the embodiment shown in the figure, and a similar human hand-like grasping effect can be achieved as long as there are alternating undulations.

[0043] See also Figure 2 Combination Figure 6As shown, the lower shell 12 is provided with a plurality of mounting holes 121 around the driving wheel 25, and a plurality of massage claws 30 are installed one by one in each mounting hole 121. Specifically, each massage claw is composed of a swing arm 31 and a silicone claw head 32. The middle part of the swing arm 31 is relatively rotatably installed in the corresponding rotation shaft holes 122 opened on both sides of the mounting hole 121 through a first rotation shaft 311, so that the swing arm 31 can only rotate around the first rotation shaft 311 relative to the lower shell 12. The inner end of the swing arm 31 is relatively rotatably connected to the outer side of the push block 28 through a second rotation shaft 312. The lower shell 12 is also provided with a guide rail 123 on the inner side of each mounting hole 121 close to the driving wheel 25, and each push block 28 is adapted to be installed in the guide rail 123 so as to be guided by the guide rail 123 and can only slide up and down. In this way, the rotation of the driving wheel 25 drives the push block 28 to reciprocate up and down along a circle of wavy guide grooves 26, thereby pushing the swing arm 31 to swing back and forth around the first rotating shaft 311 to open and close. A clamping arm 313 extends from the outer end of the swing arm 31 and extends out of the mounting hole 121. The silicone claw head 32 is provided with a clamping groove 321. The clamping arm 313 is clamped in the clamping groove 321 of the silicone claw head 32, and the silicone claw head 32 is fixed on the swing arm 31 to swing back and forth with the swing arm 31. The silicone claw head 32 is provided with a plurality of massage teeth 322, and in the process of opening and closing of the silicone claw head 32 with the swing arm 31, it can simulate the grasping and kneading massage of human hands.

[0044] See also Figure 1 and Figure 2 As shown, the massage device 100 according to the above embodiment of the present application is further provided with a control mainboard 41 at the upper part of the partition shell 13 in the upper shell 11, and the main control mainboard 41 is electrically connected to the drive motor 21, supplies power to the drive motor 21 and controls the operation of the drive motor 21. The upper shell 11 is also provided with a control button 42 and an indicator light 43, which are electrically connected to the control mainboard 41 respectively. A battery electrically connected to the control mainboard 41 can also be provided in the upper space between the upper shell 11 and the partition shell 13.

[0045] The massage device 100 according to the above embodiment of the present application drives the multiple push blocks 28 to move up and down reciprocatingly through a circle of wavy guide grooves 26 formed circumferentially around the driving wheel 25, thereby driving the multiple massage claws 30 to simultaneously close inward or open outward, thereby achieving a grasping and kneading massage imitating human hands, and the operation is smooth and not prone to jamming, thereby improving the user's comfort. The massage device 100 according to the above embodiment of the present application can not only be used alone for grasping and kneading massage of the head, shoulder neck and joints, but can also be integrated into various massage devices as a massage component.
