The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0041] Nowadays, there are many types of massage equipment, such as large massage chairs, massage pillows, massage belts, massage foot baths, etc., as well as small massage eye masks, fascia guns and other health massage products.

[0042] That is, the massage equipment can be in the form of a plurality of massage devices installed therein, such as a massage chair, a massage foot bath, etc., which is equipped with a plurality of massage device modules for massaging different parts of the human body. Of course, the massage equipment can also be in the form of a separate massage device, such as a massage eye mask, a fascia gun or other health massage products, etc., which are presented in the form of a separate small massage device.

[0043] Among the numerous massage devices, most are designed to simulate human massage techniques as closely as possible, hoping to achieve operations such as pressing and kneading on human body parts to better stimulate relevant acupuncture points. In related technologies, massage devices that achieve the above-mentioned simulated human massage techniques, such as fascia guns, foot baths, massage chairs, massage eye masks, and massage belts, mostly use simple tapping or linear reciprocating motion to impact human skin tissue, thereby pressing and stimulating the skin. However, the massage effect of such massage methods needs to be improved.

[0044] Therefore, in order to improve the massage effect of the massage device, the present application proposes a new massage device solution.

[0045] Please refer to Figures 1 to 3In an embodiment of the present application, the present application provides a massage device 1, including a shell 10, an electronic control module 20, a drive motor 30, a rotating and telescopic mechanism 40, an actuator 50 and a flexible member 60; the shell 10 is provided with a accommodating cavity (not marked); the electronic control module 20 is installed on the shell 10 and is arranged in the accommodating cavity; the drive motor 30 is installed on the shell 10 and is electrically connected to the electronic control module 20; the rotating and telescopic mechanism 40 is transmission-connected to the output shaft of the drive motor 30 and has a driving end, and the driving end is configured to perform a compound motion of telescoping and rotating relative to the shell 10 under the drive of the drive motor 30; the actuator 50 is fixedly connected to the driving end; the flexible member 60 is installed on the actuator 50 and is used to contact the part to be massaged.

[0046] The actuating member 50 is driven by the driving end to perform a compound movement of expansion and contraction and rotation relative to the housing 10 , and the flexible member 60 is linked to the actuating member 50 .

[0047] The shell 10 of the present application includes an outer shell 11 and a mounting bracket 12, wherein the accommodating cavity can be defined by the outer shell 11 or defined by the outer shell 11 and the mounting bracket 12 together. The electronic control module 20 is arranged in the accommodating cavity, so that the electronic control module 20 can be protected by the shell 10, thereby improving the safety of the entire machine during use and extending the service life of the entire machine.

[0048] The shell 11 can be made of plastic, or of metal, such as aluminum alloy, iron alloy, etc., and this application does not impose any restrictions on this. The shell 11 can be cylindrical, or its cross section can be elliptical, polygonal, etc. When the massage device 1 of the present application is used as a massage module in a large massage device (such as a massage chair, foot bath, etc.), the shell 11 not only becomes a mounting carrier for other components in the massage device 1, but also serves as a carrier for installing the entire massage device 1 into the frame of the large massage device. Of course, when the massage device 1 is used as an independent product, the shell 11 can be suitable for the user to hold. The connection method between the mounting bracket 12 and the shell 11 can be a combination of one or more forms such as screw connection, bonding, and clamping, wherein the material of the mounting bracket 12 can be the same as the material of the shell 11, or different from the material of the shell 11.

[0049] The drive motor 30 can be mounted on the housing 11, or mounted on the mounting bracket 12, or can be fixed by both the housing 11 and the mounting bracket 12. The drive motor 30 of the present application can be a reduction drive motor, that is, it includes two parts: a motor body and a reducer. In this way, the speed and torque output by the output shaft of the drive motor 30 can meet the massage requirements. Of course, if the motor body can meet the speed and torque required for massage, the reducer can also be omitted. The motor body can be a rotary drive motor, a motor, etc.

[0050] When the massage device 1 is formed as a small massage device that can be used alone, the electronic control module 20 includes a battery 21 and a control circuit board 22. The battery 21 and the drive motor 30 are both electrically connected to the control circuit board 22, wherein the battery 21 can be a disposable dry cell 21 or a rechargeable lithium battery 21. When the battery 21 is in the form of a rechargeable battery 21, the present application further installs a charging base 23 on the housing 11. The charging base 23 is electrically connected to the control circuit board 22 and can charge the battery 21. The charging base 23 can be in the form of two charging contacts and can also be magnetic, that is, during the charging process, the charging base 23 and the external charging plug can be attracted by magnetism, and the electrical connection between the charging base 23 and the external charging head can be quickly achieved. In other embodiments, the charging base 23 can also be formed as a charging coil, that is, the charging base 23 can be coupled with an external charging coil for charging. Furthermore, the massage device 1 of the present application also includes a control button 24, which can be a physical button, a touch button, etc. provided on the housing 11. The control button 24 can realize the start, stop and gear selection functions of the massage device 1. Of course, the control circuit board 22 can also be provided with a wireless interaction module, such as an infrared transmission module, Bluetooth, WIFI module, etc., so that the massage device 1 of the present application can also be remotely controlled through an APP on a mobile terminal or through a remote control, thereby improving the convenience of use of the massage device 1.

[0051] Of course, when the massage device 1 is a massage module in a large massage device, the electronic control module 20 may not include the battery 21, but instead be powered by a power module in the large massage device.

[0052] Furthermore, the electronic control module 20 of the present application can be mounted and fixed on the mounting bracket 12, thereby forming a modular installation and improving assembly efficiency. Specifically, the mounting bracket 12 can be provided with a mounting slot to fix the battery 21 and a screw lock position to fix the control circuit board 22.

[0053] The actuator 50 of the present application is used to transmit the movement of the rotating and telescopic mechanism 40, and also serves as a carrier for installing the flexible member 60. The actuator 50 can be made of plastic. When the actuator 50 is driven by the rotating and telescopic mechanism 40, the actuator 50 performs a rotational and telescopic movement together with the flexible member 60. That is, the actuator 50 and the flexible member 60 perform two compound movements of rotation and telescopic movement during the working process, namely, a spiral propulsion movement.

[0054] The flexible member 60 can be made of silicone material, so that it is soft in texture and can achieve effective buffering during contact with the human body, especially during massage, to ensure safety during the massage process. It is understandable that when the flexible member 60 has the above-mentioned functions, other materials can also be selected. During the operation of the massage device 1, there will be no mutual interference between the flexible member 60 and the shell 11, that is, the flexible member 60 and the shell 11 are separately arranged, which can ensure the smoothness of the spiral movement process of the above-mentioned flexible member 60. In the case where the flexible member 60 and the shell 11 are separately arranged, the flexible member 60 and the shell 11 can be in contact, such as a sliding sleeve relationship, or can be in a completely non-contact form.

[0055] It is understandable that the movement process of the flexible member 60 of the present application during the massage process is a spiral propulsion action. Therefore, during the spiral propulsion process, it can produce a pressing effect on the massage area, and during the rotation process, it can produce a kneading effect on the skin. It is understandable that kneading the skin helps to accelerate blood circulation, and because the effective area is larger, the massage effect can be effectively improved. That is, the massage device 1 of the present application, compared with the traditional structural design, which is only a simple linear impact or knocking action, can better simulate the actual kneading and pressing technique, thereby improving the massage effect. At the same time, the present application uses the flexible member 60 to contact the user's skin. When implementing the above-mentioned kneading and pressing process, the flexible member 60 can also achieve a good buffering effect, so the entire massage process is also relatively safe.

[0056] In one embodiment, the rotary telescopic mechanism 40 includes a drive shaft 41, a drive screw 42, a sleeve 43, and a pin 44. The drive shaft 41 is coaxially arranged with the output shaft of the drive motor 30. Of course, the drive shaft 41 of the present application can also be a lengthened design of the output shaft of the drive motor 30 to form the drive shaft 41. The drive screw 42 has the above-mentioned drive end, and the drive screw 42 is provided with an axial hole 421 inside and a spiral groove 422 outside. The drive screw 42 is sleeved on the outside of the drive shaft 41 through the axial hole 421. The drive screw 42 and the drive shaft 41 are relatively fixed in the circumferential direction and can move axially relative to the drive shaft 41. Specifically, the drive shaft 41 has a polygonal cross-section, such as a hexagon, and the shape of the axial hole 421 is adapted to the shape of the drive shaft 41. In this way, the drive shaft 41 and the drive screw 42 can be mutually limited and fixed in the circumferential direction, while being able to slide relative to each other in the axial direction.

[0057] The shaft sleeve 43 has a limiting hole 431 and is fixedly connected to the above-mentioned mounting bracket 12, and the drive screw 42 is passed through the limiting hole 431; specifically, the mounting bracket 12 includes a cover plate 13 and a magazine shell 14, and a mounting cavity 141 is provided in the magazine shell 14, and the drive motor 30 and the shaft sleeve 43 are both accommodated in the mounting cavity 141, and the side of the shaft sleeve 43 away from the drive motor 30 can be locked with the cover plate 13 by screws, wherein the cover plate 13 is sealed on the end of the cylindrical shell 11, and the cover plate 13 is also provided with an avoidance hole corresponding to the limiting hole 431, so that the drive screw 42 partially passes through the mounting bracket 12.

[0058] The pin 44 is fixed to the sleeve 43 and partially inserted into the spiral groove 422. In the present application, the pin 44 and the spiral groove 422 are loosely matched. In this arrangement, when the drive shaft 41 rotates and drives the drive screw 42 to rotate, the pin 44 will abut against the groove wall of the spiral groove 422 and act on the drive screw 42, thereby driving the drive screw 42 to slide along the axial direction of the drive shaft 41. In this way, the drive screw 42 drives the actuator 50 and the flexible member 60 to perform a compound movement of rotation and extension.

[0059] It is understandable that the specific structure of the rotating telescopic mechanism 40 can also be other, for example, the sleeve 43 is fixed to the output shaft of the drive motor 30, and the drive screw 42 is not directly connected to the output shaft of the drive motor 30, or the sleeve 43 is connected to the drive motor 30 in a transmission manner, such as Figure 6 and Figure 7 In the exemplary embodiment, the rotary telescopic mechanism 40 includes a drive screw 42, a sleeve 43, a pin 44 and a transmission gear set 45. The drive screw 42 has a drive end, and a spiral groove 422 is provided on the outside of the drive screw 42; the transmission gear set 45 includes an input wheel 451 and an output wheel 452 that are transmission-connected. Of course, a transmission wheel (not shown) is also provided between the input wheel 451 and the output wheel 452. The input wheel 451 is fixedly connected to the output shaft of the drive motor 30; the sleeve 43 has a limiting hole 431, and the sleeve 43 can be rotatably sleeved on the drive screw 42 and is rotationally connected to the housing 10. The sleeve 43 is fixed to the output wheel 452 and rotates together. Figure 7 The output wheel 452 is fixedly connected to the sleeve 43 by screw connection; the pin 44 is fixed to the sleeve 43 and / or the output wheel 452 and partially inserted into the spiral groove 422. In one implementation, the pin 44 is clamped and limited by the output wheel 452 and the sleeve 43.

[0060] In this embodiment, the driving motor 30 outputs power to the driving screw 42 through the transmission gear set 45, wherein the rotating axes of the multiple gears in the multiple transmission gear sets 45 can be arranged in a layout parallel to the output axis of the driving motor 30, so that the driving motor 30 and the driving screw 42 can be arranged in a layout parallel to each other, so that the size of the entire massage device 1 along the axial direction of the driving motor 30 can be correspondingly reduced, thereby facilitating its installation as a module, or facilitating its storage and transportation packaging when it is used as a separate unit.

[0061] The housing 10 of this embodiment also includes an outer shell 11 and a mounting bracket 12 disposed within the outer shell 11. The drive motor 30 is fixedly connected to the mounting bracket 12. The shaft sleeve 43 is rotatably connected to the mounting bracket 12. The drive screw 42 partially extends through the mounting bracket 12 and is fixedly connected to the actuator 50. Specifically, the mounting bracket 12 can also be configured in the form of a cover plate 13 and a housing 14. The shaft sleeve 43 is constrained between the cover plate 13 and the housing 14, and the shaft sleeve 43 is constrained in a mounting cavity 141 within the housing 14, and is rotatably connected to the housing 14.

[0062] In an embodiment of the present application, the flexible member 60 includes a base portion 61 fixed to the actuator 50 and a massage protrusion 62 protruding from the base portion 61, and the massage protrusion 62 is used to contact the part to be massaged. The massage protrusion 62 of the present application and the base portion 61 can be in the form of an integral structure, or a separate structure and fixedly connected together. The provision of the massage protrusion 62 can enhance the massage effect. Specifically, the massage protrusion 62 is at least partially provided in a spiral shape. Among them, the massage protrusion 62 can be an elongated strip as a whole and configured in a spiral shape. Of course, the massage protrusion 62 can also be in the form of a plurality of convex hulls, and the plurality of convex hulls are arranged to form a spiral shape.

[0063] like Figure 4 As shown, the actuator 50 can extend in a direction away from the housing 10 and have a certain length, and the base portion 61 is sleeved on the outside of the actuator 50, and the massage protrusion 62 is protruded from the outer wall of the base portion 61. Or, as Figures 1 to 3 As shown, the actuator 50 is formed with a receiving cavity 501. The base portion 61 is mounted in the receiving cavity 501 and is formed with a groove 611. The massage protrusion 62 is protruding from the groove wall surface of the groove 611. The massage protrusion 62 can be located solely on the groove side wall surface of the groove 611, or can be located simultaneously on the groove side wall and the groove bottom wall surface of the groove 611. In the embodiment in which the base portion 61 is mounted in the receiving cavity 501 and is formed with the groove 611, the flexible member 60 can achieve better adaptive deformation during the massage process and form a negative pressure with the massaged area, thereby achieving a better receiving and contact effect.

[0064] In the above embodiments, the fixed connection method of the actuator 50 and the driving screw 42 can be bonding, connection through a threaded connector, threaded connection, etc., and this application does not impose any limitation on this.
