Description

Technical Field

[0001] This application relates to health care and physiotherapy devices, and more particularly to a massage mechanism and a massage device employing the massage mechanism. 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 and lacking exercise for a long time, bringing various sub-healthy problems such as headaches, shoulder and neck soreness, and knee discomfort. Therefore, various massagers are very popular. By means of 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 massage actions of the massager closer 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 human hand massage. In the internal space assembled by the front shell and the bottom shell, there is a driving mechanism that drives the swing arm extending from 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-tip contacts at the end of the silicone brush achieve combing and pinching, and can imitate the human hand to pinch and massage the head. 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 cam is not smooth enough during actual massage use and is also prone to failures, resulting in poor user experience.

Detailed implementation manners

[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the 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. And, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] Figure 1 and Figure 2 respectively show structural schematic diagrams of different angles of the massage mechanism 10 according to an embodiment of the present application. Refer to Figure 1 and Figure 2As shown in the figure, the massage mechanism 10 mainly consists of a drive motor 11, a worm 12, a helical gear 13, a transmission gear set 14, a pull rod 15, a pushing member 16, a swing rod 17 and a massage head 18. The drive motor 11 is horizontally arranged, and the worm 12 is fixedly connected coaxially with the drive motor 11. The helical gear 13 is arranged on one side of the worm 12 and meshes with the worm 12, thereby converting the rotation of the drive motor 11 around the horizontal axis into the rotation of the helical gear 13 around the vertical axis. The transmission gear set 14 includes an input gear 141, an intermediate transmission gear 142, an output gear 143 and four eccentric gears 144. The input gear 141 meshes with the helical gear 13, thereby being in transmission connection with the drive motor 11. The intermediate transmission gear 142 meshes with the input gear 141, and the output gear 143 meshes with the intermediate transmission gear 142. The four eccentric gears 144 are arranged around the output gear 143 and respectively mesh with the output gear 143. The intermediate transmission gear 142 is in transmission connection between the input gear 141 and the output gear 143, and is used to transmit the rotation of the input gear 141 driven by the drive motor 11 to the output gear 143. The number of the intermediate transmission gears 142 is at least one, and can be adjusted according to actual situations, and is not limited to the illustrated embodiment. The four eccentric gears 144 are evenly distributed around the output gear 143, and are respectively used to drive the four swing rods 17 to swing synchronously back and forth with the reciprocating rotation of the output gear 143 through the four pull rods 15 and the four pushing members 16, thereby realizing the synchronous pinching and kneading of the four massage heads 18. Similarly, in order to achieve the effect of pinching and kneading massage, the number of the eccentric gears 144 and the corresponding pull rods 15, pushing members 16, swing rods 17 and massage heads 18 is at least two, and can be adjusted according to actual situations, and is not limited to the illustrated embodiment.

[0026] For specific reference, see Figure 2 in combination with Figure 3As shown, a first mounting shaft 1441 extending along a first axis parallel to the rotation axis of the eccentric gear 144 protrudes downward from the bottom of the eccentric gear 144. One end of the pull rod 15 is provided with a first shaft hole 151 for the first mounting shaft 1441 to be inserted, so that one end of the pull rod 15 is eccentrically rotatably connected to the bottom of the eccentric gear 144 around the first axis. A second shaft hole 152 is provided at the other end of the pull rod 15. A second mounting shaft 162 extending along a second axis parallel to the rotation axis of the eccentric gear 144 protrudes upward from the top of the pushing member 16 and is inserted into the second shaft hole 152 from below the pull rod 15, so that the other end of the pull rod 15 is rotatably connected to the pushing member 16 around the second axis. An installation groove 161 is provided at the bottom of the pushing member 16. The installation groove 161 has a certain depth upward. One end of the swing rod 17 is provided with a first connecting shaft 171 perpendicular to the second axis and is inserted into the installation groove 161 from below the pushing member 16 to achieve a rotational connection with the pushing member 16. The other end of the swing rod 17 is rotatably connected to an external structure through a second connecting shaft 172 parallel to the first connecting shaft 171. The massage head 18 is installed on the installation arm 173 extending from the other end of the swing rod 17. Thus, the drive motor 11 drives the input gear 141 of the transmission gear set 14 to rotate through the worm 12 and the helical gear 13, drives each eccentric gear 144 to rotate synchronously through the output gear 143, and then pulls each pushing member 16 to linearly reciprocate in the direction shown by the arrow 91 in Figure 3 under the restriction of the swing rod 17 through each pull rod 15, pushes each swing rod 17 to reciprocally swing around the second connecting shaft 172, and then drives each massage head 18 to reciprocally open and close in the direction shown by the arrow 92 in Figure 3 to realize the pinching and kneading massage action. In a specific embodiment, the massage head 18 is a silicone claw head clamped on the installation arm 173 of the swing rod 17, and a plurality of massage teeth 181 are further provided on the massage head 18, which can better simulate the human hand to perform pinching and kneading massage during the process of opening and closing while reciprocally swinging with the swing rod 17.

[0027] Based on the massage mechanism 10 of the foregoing embodiment, the present application further proposes a massage device adopting the massage mechanism 10. Figure 4 And Figure 5 respectively show schematic diagrams of the external structure of the massage device 100 according to an embodiment of the present application from different angles, Figure 6 and Figures 4 - 6As shown, the massage device 100 mainly consists of a housing 20 and the massage mechanism 10 of the foregoing embodiment accommodated within the housing 20. Among them, the mounting arm 173 of each swing rod 17 of the massage mechanism 10 extends out from the first mounting hole 221 opened at the bottom of the housing 20, and each massage head 18 is mounted on the mounting arm 173 extending out of the housing 20. During use, when the user holds the housing 20, the clamping and kneading massage can be achieved through the synchronous reciprocating opening and closing of the massage heads 18 of the massage mechanism 10.

[0028] For specific reference Figure 6 As shown, the housing 20 includes an upper shell 21, a lower shell 22, a gear mounting bracket 23 and a swing rod mounting bracket 24 disposed in the internal space formed by the combination of the upper shell 21 and the lower shell 22. The gear mounting bracket 23 is located in the middle of the internal space formed by the combination (such as buckling) of the upper shell 21 and the lower shell 22. The input gear 141, the intermediate transmission gear 142, the output gear 143 and the eccentric gear 144 of the transmission gear set 14 can all be mounted and supported on the gear mounting bracket 23. The swing rod mounting bracket 24 is located within the lower shell 22, and each swing rod 17 is rotationally supported on the swing rod mounting bracket 24 through a second connecting shaft 172. In this way, the linear reciprocating movement of the pushing member 16 can drive the swing rod 17 to rotate around the second connecting shaft 172 to achieve reciprocating swinging. Corresponding to each swing rod 17 at the bottom of the lower shell 22, a first mounting hole 221 is opened for the mounting arm 173 of the swing rod 17 to extend out and provide a reciprocating swinging space, and a deformed silica gel sleeve 25 is embedded in each first mounting hole 221. The mounting arm 173 extends out from the second mounting hole 251 opened in the middle of the deformed silica gel sleeve 25. The deformed silica gel sleeve 25 can seal the first mounting hole 221 of the lower shell 22 (see Figure 5 shown), achieving the purpose of waterproof and dustproof. At the same time, the deformation of the deformed silica gel sleeve 25 can also provide space for the reciprocating swinging of the swing rod 17.

[0029] See again Figure 6 Combined with Figure 4 As shown, a control circuit board 31 is provided at the upper part of the gear mounting bracket 23 within the upper shell 21. The control circuit board 31 is electrically connected to the drive motor 11 of the massage mechanism 10. Control buttons 32 and a power supply interface 33 are also provided on the upper shell 21 and are electrically connected to the control circuit board 31 for supplying power to the drive motor 11 and controlling the operation of the drive motor 11. The power supply interface 33 can be, for example, a USB interface. A rechargeable battery can also be accommodated within the upper shell 21 and is electrically connected to the control circuit board 31 to achieve portable power supply. Further see Figure 6 Combined with Figure 5As shown, in the middle of the inner side of the bottom of the lower housing 22, there is also an LED lamp board 34. A number of infrared LED lamps are provided on the LED lamp board 34. A plurality of light guide members 35 (such as transparent plastic parts) are embedded around the LED lamp board 34 at the bottom of the lower housing 22. The LED lamp board 34 is electrically connected to the control circuit board 31 in the upper housing 21 through a wire, and its power supply and operation can also be controlled through the control button 32. The infrared light emitted by the LED lamp board 34 is exported through the plurality of light guide members 35 and then irradiated onto the massage part, so that the infrared physiotherapy function can be realized while performing the pinching and kneading massage. A heating element 36 is also arranged in the area surrounded by the plurality of light guide members 35 at the bottom of the lower housing 22. The heating element 36 can also be electrically connected to the control circuit board 31 in the upper housing 21 through a wire. When the heating element 36 works, it generates heat, and the hot compress function can be realized by fitting the massage part.

[0030] The massage device 100 according to the above embodiment of the present application adopts the aforementioned massage mechanism 10. At least two pull rods 15 eccentrically rotated at the bottom of at least two eccentric gears 144 that rotate synchronously are used to pull at least two pushing members 16 to linearly reciprocate. Then, through the at least two pushing members 16 acting on at least two swing rods 17, the at least two swing rods 17 are reciprocally swung, and then at least two massage heads 18 are driven to simultaneously move inwards or outwards, realizing the imitation of human hand pinching and kneading massage.
