Description

Technical Field

[0001] This utility model relates to the field of massagers, and more particularly to an abdominal massager. Background Technology

[0002] An abdominal massager is a device that uses physical vibration or kneading to stimulate the abdomen, helping to promote intestinal peristalsis and relieve bloating and constipation. Technically, it primarily works by using a motor to drive the massage head to rotate, thereby massaging the abdomen and achieving corresponding therapeutic effects.

[0003] Taking the design proposed in CN221308759U as an example, it mainly includes a shell body and a turntable located on the outside of the shell body. The shell body houses the main control board, drive components, and battery. The drive components drive the turntable, which has a rotating shaft mounted on it, and massage rollers are installed on the shaft. The turntable has a cavity for holding moxibustion materials, and a cap with a perforated groove is installed on the cavity. The drive components include a motor and transmission gears. A first transmission gear is located below the turntable, meshing with the second transmission gear. This design directly drives the turntable to rotate via the internal motor and transmission gears, causing the three massage rollers to rotate and perform abdominal massage. Like other existing abdominal massage devices, this design integrates the motor inside the shell body, which undoubtedly occupies valuable structural space. Furthermore, other components such as transmission mechanisms need to be stacked near the motor to achieve transmission, ultimately resulting in existing abdominal massage devices being very thick, generally exceeding 100mm. Such thick devices pose significant inconvenience in use and portability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an abdominal massager with a thinner thickness.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an abdominal massager, including a fixed shell, a rotating disk rotatably mounted on the fixed shell, at least one massage head fixedly mounted on the rotating disk, and a motor for driving the rotating disk to rotate. The massage head has an internal cavity, and the motor is located within the cavity of the massage head. The massage head is positioned on the surface of the rotating disk. By creating a cavity inside the massage head and placing the motor within that cavity, the motor's arrangement no longer occupies structural space within the fixed shell, allowing the fixed shell to be made thinner, thus reducing the thickness of the abdominal massager.

[0006] One embodiment for the transmission connection between the motor and the rotating disk can be the following: It includes a reduction gearbox and a fixed gear. The fixed gear is fixedly mounted on a fixed housing. The motor's output shaft has an output shaft gear that meshes with the input end of the reduction gearbox, while the output end of the reduction gearbox meshes with the fixed gear. In actual use, the motor's output shaft rotates, transmitting driving force to the fixed gear through the output shaft gear and the reduction gearbox. The reduction gearbox reduces the high speed of the motor's output shaft before transmitting it to the fixed gear. Because the fixed gear is fixed to the fixed housing, it does not rotate itself, while the motor rotates with the rotating disk. This, in turn, causes the motor's output shaft and the motor itself to rotate around the axis of the fixed gear. Since the motor is located inside the cavity of the massage head, the massage head and the rotating disk also rotate together, achieving a kneading and stimulating effect on the abdomen.

[0007] As a preferred embodiment for achieving rotation between the rotating disk and the fixed gear, the following scheme can be selected: A bearing is included, fixedly mounted on the fixed gear, coaxially arranged with the fixed gear, and coaxially arranged with the rotating disk. The rotating disk is rotatably mounted on the fixed gear via the bearing. The fixed gear is a stationary structure, the bearing is fixedly mounted on the fixed gear, and the rotating disk is connected to the bearing, thereby enabling the rotating disk to rotatably mount on the fixed gear via the bearing.

[0008] As a preferred arrangement of the circuit board, it can be fixedly mounted on a rotating disk. Furthermore, to ensure the circuit board consistently receives power from the battery as the disk rotates, the following solution can be chosen: A battery, a large lead ring, and a small lead ring are respectively mounted on the fixed housing. The large and small lead rings are coaxially aligned, and the battery is electrically connected to both. The large and small lead rings are coaxially aligned with the rotating disk. Two spring pins are mounted on the circuit board, each electrically connected to one of the large or small lead rings. During the rotation of the disk, although the two spring pins rotate with the circuit board and the disk, they always maintain contact with their corresponding large and small lead rings, thus allowing the battery's power to be delivered to the circuit board through the large and small lead rings and the spring pins.

[0009] Preferably, the device includes a control board, which is electrically connected to the battery via battery wires, and also electrically connected to a large conductor loop and a small conductor loop via control board wires. The control board is positioned between the battery and the large and small conductor loops, enabling current control on the large and small conductor loops, thus controlling the start and end of power supply and functioning as a switch.

[0010] To achieve a synergistic therapeutic effect between the heat therapy and massage functions, the following approach can be chosen: At least one infrared light window is positioned on a rotating disc, evenly distributed around the disc's axis of rotation. Massage heads are also evenly distributed around the disc's axis, with the infrared light windows and massage heads alternating in their arrangement. The infrared light windows release heat to provide heat therapy to the abdominal skin, while the massage heads squeeze and knead to massage the abdomen. Because of the alternating arrangement of the infrared light windows and massage heads, the heated abdominal area receives immediate massage, significantly enhancing the abdominal massage effect and promoting intestinal peristalsis, thus relieving bloating.

[0011] When using an abdominal massager, the center of the device is generally close to the location of the navel. To achieve the effect of moxibustion on the navel, the following configuration can be selected: It includes moxibustion holes, which are located within a circular area concentric with the rotating disc, with the outlet of the moxibustion hole facing the same direction as the massage head. The location of the moxibustion holes within the concentric circular area of ​​the rotating disc ensures that the heat from the moxibustion can be effectively transferred to the navel, achieving the corresponding therapeutic effect.

[0012] As one embodiment of moxibustion therapy, the following scheme can be selected: It includes a pressure plate, with moxa wool placed in the cavity between the pressure plate and the moxibustion hole. A heating element for heating the moxa wool is installed on the pressure plate. A cavity for containing the moxa wool is formed between the pressure plate and the moxibustion hole. In actual use, the heating element heats the moxa wool, allowing the heat from the moxibustion to be transferred to the navel through the moxibustion hole.

[0013] Preferably, the motor is a brushless motor. Since the motor is housed within the cavity of the massage head, the advantages of brushless motors—long service life and maintenance-free operation—are well-suited to the scenario described in this solution, thereby improving ease of use and the quality stability of the abdominal massager.

[0014] The beneficial effects of this utility model are: First, by adjusting the motor's placement, moving it from inside the fixed housing to inside the massage head, space is saved within the fixed housing, providing a structural basis for using a thinner fixed housing. Simultaneously, the original drive method of a single large motor driving multiple massage heads is replaced with multiple small motors driving multiple massage heads, effectively reducing the motor's size and cleverly achieving efficient motor placement.

[0015] Second, through the gear meshing between the motor's output shaft, the reduction gearbox, and the fixed gear, not only is the massage head driven, but the stable and reliable driving force of the massage head can also be guaranteed during the kneading and stimulating of the abdomen by taking advantage of the stability and reliability of gear transmission.

[0016] Third, by setting up an infrared light window, heat therapy is achieved during the massage process, improving the massage effect. Simultaneously, it can also provide moxibustion therapy to the navel.

[0017] This invention is particularly applicable to the structural design of ultra-thin abdominal massage devices. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1 to 10 The image shows an embodiment of the abdominal massage device. Among them, Figures 1 to 4 The diagram shows the external structure of the abdominal massager, including a fixed housing 45. A massage head 36, an infrared light window 32, and a moxibustion hole 28 are located in the central area of ​​the fixed housing 45. Handles for gripping are located on the left and right sides of the fixed housing 45. The user holds the handles on both sides and places the massage head 36, infrared light window 32, and moxibustion hole 28 on their abdomen to achieve self-massage therapy. The massage head 36, infrared light window 32, and moxibustion hole 28 are all located on the same plane of the rotating disk 51, and all three face towards the user's abdomen. The rotating disk 51 is circular and rotates around its axis. In this embodiment, there are three infrared light windows 32, evenly distributed around the axis of rotation of the rotating disk 51, and three massage heads 36, also evenly distributed around the axis of rotation of the rotating disk 51. The infrared light windows 32 and massage heads 36 are alternately arranged. Two heating lamps 75 are installed inside the infrared light window 32, one emitting red light and the other infrared light. The moxibustion hole 28 is a small hole for transferring moxibustion heat to the outside. The moxibustion hole 28 is located within a circular area concentric with the rotating disc 51, and the outlet of the moxibustion hole 28 faces the same direction as the massage head 36, ensuring that the moxibustion hole 28 is as close as possible to the user's navel during use. A button 47, electrically connected to the control board 99, is located on the back of the fixed housing 45, used to select various function modes of the abdominal massager. Screws 50 on the back of the fixed housing 45 pass through the fixed housing hole 118 on the fixed housing 45 and the mounting hole 74 on the fixed gear 61, thereby fixing the fixed housing 45 and the fixed gear 61 together.

[0031] Figures 5 to 8The diagram shows the internal structure of the abdominal massager. The three massage heads 36 are evenly distributed around the axis of the fixed gear 61. The fixed gear 61 is coaxial with the rotating disk 51, meaning the angle between adjacent massage heads 36 is 120 degrees. The surface of the massage heads 36 can be made of conventional materials, such as rubber. The interior of each massage head 36 is hollow, and a motor 83 is housed within the cavity formed by this hollow structure. In this embodiment, the motor 83 is a brushless motor. The extension direction of the output shaft of the motor 83 is parallel to the axial direction of the fixed gear 61, and an output shaft gear 81 is provided at the end of the output shaft of the motor 83. Each motor 83 is correspondingly provided with a reduction gearbox 58, which is a gear set composed of multiple gears. This reduction gear set reduces the high speed at the input end of the reduction gearbox 58 to the low speed at the output end of the reduction gearbox 58. This reduction gear set structure is a common existing structure. The output shaft gear 81 meshes with the input end of the reduction gearbox 58, and the output end of the reduction gearbox 58 meshes with the fixed gear 61. Furthermore, the rotating disk 51 and the fixed gear 61 are rotatably connected via a bearing 63 fixedly mounted on the fixed gear 61, meaning that when the rotating disk 51 rotates, the fixed gear 61 does not rotate. Thus, when the output shaft of the motor 83 rotates, the high speed of the output shaft gear 81 is transmitted to the fixed gear 61 at a reduced speed through the reduction gearbox 58. Since the fixed gear 61 does not rotate, the reduction gearbox 58 and the motor 83 revolve around the fixed gear 61 at the aforementioned reduced speed, thus forming a planetary gear set motion. The rotating motor 83 drives the rotating disk 51 to rotate, causing the massage head 36 to rotate synchronously, thereby achieving the corresponding massage effect. The motor 83 is electrically connected to the circuit board 55, which provides power to the motor 83. The circuit board 55 is fixedly mounted on the rotating disk 51; when the rotating disk 51 rotates, the circuit board 55 also rotates with the rotating disk 51, while the motor 83 and the circuit board 55 remain relatively stationary. The pressure plate 88 can be made of aluminum alloy. It can also engage with the fixed gear 61 to secure the bearing 63 to the gear 61. The pressure plate 88 contains a heating element 66, typically an electric heating wire. Moxa wool 78 is placed in the cavity between the pressure plate 88 and the moxibustion hole 28. The heating element 66 heats the moxa wool 78, allowing the heat from the moxibustion to be released through the moxibustion hole 28. When the moxa wool 78 needs to be replaced, the pressure plate 88 can be easily separated from the fixed gear 61 for convenient replacement.

[0032] like Figures 7 to 10As shown, two spring pins 72 are provided on the circuit board 55, and the spring pins 72 are set perpendicular to the circuit board 55. The circuit board 55 is fixedly mounted on the rotating disk 51, so the circuit board 55 will rotate with the rotating disk 51. A large wire ring 106 and a small wire ring 112 are respectively provided at the bottom of the middle area of ​​the fixed housing 45. Both the large wire ring 106 and the small wire ring 112 are circular wires. The large wire ring 106 and the small wire ring 112 are coaxially arranged with the fixed gear 61, and the diameter of the large wire ring 106 is larger than that of the small wire ring 112. The large wire ring 106 is in close contact with one of the two spring pins 72, and the small wire ring 112 is in close contact with the other of the two spring pins 72. When the spring pin 72 rotates with the circuit board 55, the spring pin 72 always remains in close contact with its corresponding large wire ring 106 or small wire ring 112, thereby enabling continuous power supply to the circuit board 55 during its rotation. Two batteries 91 are located inside the handles on the left and right sides of the fixed housing 45, respectively. The batteries 91 are electrically connected to the control board 99 via battery wires 94. The control board 99 is connected to the large lead ring 106 and the small lead ring 112 via control board wires 102. The control board 99 is also connected to the aforementioned button 47. Through the button 47 and the control board 99, the various therapeutic modes of the abdominal massage device can be controlled and selected.
