[0040] Abdominal massage devices simulate manual massage techniques by pressing and kneading the abdomen, which can promote gastrointestinal motility, help improve digestive function, and relieve problems such as indigestion and constipation. However, the structure of commonly available abdominal massage devices is often quite complex, resulting in a large overall size.

[0041] This utility model proposes an abdominal massager.

[0042] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the abdominal massager includes a main unit 100 and a massage component 200. The main unit 100 includes a drive motor 110, a gear set 120, and an internal gear ring 130. The drive motor 110 is connected to the internal gear ring 130 through the gear set 120 to drive the internal gear ring 130 to rotate. The massage component 200 includes a turntable 210 and a massage head 220. The massage head 220 is installed on the side of the turntable 210 away from the main unit 100. The turntable 210 is connected to the internal gear ring 130 to rotate with the rotation of the internal gear ring 130.

[0043] Specifically, the abdominal massager includes a main unit 100 and a massage component 200. The main unit 100 can drive the massage component 200 to rotate, thereby achieving abdominal massage. Thus, compared to an abdominal massager assembled from individual parts, this invention divides the abdominal massager into two main modules: the main unit 100 and the massage component 200, making the structure of the abdominal massager modular and simplifying its design.

[0044] Please see Figure 2 and Figure 3The main unit 100 includes a drive motor 110, a gear set 120, and an internal gear ring 130. The drive motor 110 drives the gear set 120 and the internal gear ring 130 to rotate. In one embodiment, the abdominal massager also includes a battery 190, which powers the drive motor 110. The abdominal massager also has a charging port for charging the battery 190. In other embodiments, the battery 190 can be a non-rechargeable battery, and correspondingly, the main unit 100 has a removable battery cover for replacing the battery 190. The massage assembly 200 includes a turntable 210 and massage heads 220 mounted on the turntable 210. The massage heads 220 contact the massage area. The turntable 210 is connected to the internal gear ring 130 so that the turntable 210 can rotate with the rotation of the internal gear ring 130. In one embodiment, the massage head 220 is mounted on the turntable 210, and the massage head 220 and the turntable 210 cannot rotate relative to each other; the massage head 220 can only rotate with the turntable 210. Compared to a structure where the massage head 220 rotates relative to the turntable 210, this arrangement helps to increase the friction between the massage head 220 and the abdomen, thereby increasing the massage intensity. It is understood that the drive motor 110 can rotate clockwise or counterclockwise, allowing the massage head 220 to rotate both clockwise and counterclockwise, achieving bidirectional abdominal massage.

[0045] After the main unit 100 and the massage component 200 are connected, the drive motor 110, gear set 120, internal gear ring 130, turntable 210 and massage head 220 are connected in sequence for transmission. Thus, the drive motor 110 drives the gear set 120 to rotate, the gear set 120 drives the internal gear ring 130 to rotate, causing the turntable 210 on the internal gear ring 130 to rotate accordingly, which in turn causes the massage head 220 on the turntable 210 to rotate accordingly, thereby massaging the abdomen.

[0046] In one embodiment, multiple massage heads 220 are provided. In the embodiment shown in the figures of this utility model, three massage heads 220 are provided, and the three massage heads 220 are evenly spaced on the turntable 210. In one embodiment, the center of the pattern formed by the multiple massage heads 220 connected end to end coincides with the rotation center of the turntable 210. In one embodiment, the massage heads 220 are configured as Bian stone massage heads 220.

[0047] The turntable 210 is fixed to the inner gear ring 130. The power from the drive motor 110 is reduced in speed by the gear set 120 and then transmitted to the inner gear ring 130. The inner gear ring 130 then directly drives the turntable 210 to rotate, thus enabling the abdominal massager to function. Compared to the existing technology where the power from the drive motor 110 is transmitted to different massage heads 220 via different gears, this invention directly fixes the turntable 210 to the inner gear ring 130, allowing power transmission between the main unit 100 and the massage component 200 to be achieved through only one inner gear ring 130. This allows the turntable 210 to rotate directly following the rotation of the inner gear ring 130, thereby causing the massage heads 220 on the turntable 210 to rotate accordingly. This simplifies the structure of the abdominal massager, reduces the number of parts, and decreases its overall size.

[0048] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the host 100 includes an upper shell 140 and a lower shell 150 connected together. A drive motor 110 is disposed between the upper shell 140 and the lower shell 150. A gearbox 160 is provided between the upper shell 140 and the lower shell 150. A gear set 120 is installed in the gearbox 160 and is connected to the output shaft of the drive motor 110 for transmission. An internal gear ring 130 is disposed between the lower shell 150 and the gearbox 160. The gearbox 160 is provided with a meshing port 161. Part of the gear set 120 is exposed from the meshing port to mesh with the internal gear ring 130.

[0049] Specifically, the main unit 100 includes an upper shell 140 and a lower shell 150 connected to each other. In one embodiment, the upper shell 140 and the lower shell 150 are detachably connected by a screw structure, which facilitates the maintenance of the main unit 100. The upper shell 140 and the lower shell 150 enclose a receiving space, in which the drive motor 110, the gear set 120, and the internal gear ring 130 are all disposed. The configuration of the upper shell 140 and the lower shell 150 provides protection and mounting positions for the drive motor 110, the gear set 120, and the internal gear ring 130. The upper shell 140 is located on the side of the lower shell 150 away from the massage component 200, and the drive motor 110 is mounted between the upper shell 140 and the gearbox 160. In one embodiment, the bottom of the drive motor 110 is mounted on the gearbox 160 to facilitate the output shaft of the drive motor 110 extending into the gearbox 160 and connecting with the gear set 120 for transmission. Of course, in other embodiments, the drive motor 110 and the gear set 120 may both be disposed within the gearbox 160. In one embodiment, to facilitate the installation and fixing of the drive motor 110, a motor bracket is provided on the upper housing 140, and the top of the drive motor 110 contacts the motor bracket to limit the drive motor 110 between the motor bracket and the gearbox 160, so as to prevent the drive motor 110 from shaking within the receiving space. In one embodiment, a battery bracket is also provided on the upper housing 140 for mounting and fixing the battery 190.

[0050] Understandably, when the abdominal massager is working, the gear set 120 will rotate. To avoid the influence of other components on the rotation of the gear set 120, a gearbox 160 is also provided between the upper shell 140 and the lower shell 150, and the gear set 120 is installed in the gearbox 160. To facilitate the installation of the gear set 120 into the gearbox 160, in one embodiment, the gearbox 160 includes a gearbox upper cover 164 and a gearbox lower cover 165 connected together, with the gearbox upper cover 164 located on the side of the gearbox lower cover 165 away from the massage component 200. In one embodiment, the gearbox upper cover 164 and the gearbox lower cover 165 are detachably connected by a screw structure.

[0051] To enable transmission between the drive motor 110 and the gear set 120, an input port is provided on the gearbox cover 164. The output shaft of the drive motor 110 extends into the gearbox 160 through the input port to drive the gear set 120 to rotate. For ease of explanation, the axial direction of the internal gear ring 130 is defined as the axial direction of the abdominal massage device, and the radial direction of the internal gear ring 130 is defined as the radial direction of the abdominal massage device. Along the axial direction of the abdominal massage device, the internal gear ring 130 is located between the lower shell 150 and the gearbox 160. Simultaneously, a meshing port 161 is provided on the side wall of the gearbox 160, allowing a portion of the gear set 120 to protrude from the meshing port 161, thereby enabling the internal gear ring 130 to mesh with the gear set 120. Thus, by setting up a gearbox 160 and providing a meshing port 161 on the gearbox 160, the meshing connection between the gear set 120 and the internal gear ring 130 is achieved while avoiding the exposure of the meshing teeth of the gears. Compared with the exposed meshing teeth of gears in the prior art, this is beneficial to the structural aesthetics and safety of the abdominal massage device. Here, there are no restrictions on the size and shape of the meshing port 161, as long as it can achieve the meshing of the internal gear ring 130 and the gear set 120.

[0052] Please see Figure 2 and Figure 3 In an embodiment of the present invention, the gearbox 160 includes a gearbox upper cover 164 and a gearbox lower cover 165 connected together. The gearbox lower cover 165 is provided with a receiving groove 166 for receiving the gear set 120. The receiving groove 166 protrudes in a direction away from the gearbox upper cover 164. The receiving groove 166 is provided with a meshing port 161 on the groove sidewall.

[0053] An internal gear ring 130 is fitted onto the outer wall of the receiving groove 166, and a bearing 132 is fitted between the internal gear ring 130 and the outer wall of the gearbox lower cover 165. One end of the internal gear ring 130 facing the gearbox lower cover 165 extends radially to form a limiting flange 133, and the two ends of the bearing 132 along its axial direction contact the lower shell 150 and the limiting flange 133, respectively.

[0054] Specifically, to limit the position of the gear set 120 while installing it, the lower cover 165 of the gearbox is provided with a receiving groove 166. The receiving groove 166 protrudes away from the upper cover 164 of the gearbox, thereby placing the gear in the receiving groove 166. In one embodiment, the upper cover 164 of the gearbox is provided with a fitting groove that mates with the receiving groove 166. When the upper cover 164 and the lower cover 165 of the gearbox are closed, the gear set 120 is received between the fitting groove and the receiving groove 166, thereby limiting the position of the gear set 120 in the axial and radial directions of the abdominal massager.

[0055] Understandably, the receiving groove 166 protrudes away from the gearbox upper cover 164, so that the sidewall of the receiving groove 166 is exposed on the side of the gearbox lower cover 165 away from the gearbox upper cover 164. In the embodiment shown in the figures of this utility model, there is still a distance between the sidewall of the receiving groove 166 and the outer wall of the gearbox lower cover 165, and an mounting ring groove 151 is formed between the two.

[0056] The meshing opening is located on the outer wall of the receiving groove 166. In one embodiment, the outer wall of the receiving groove 166 is cylindrical, which facilitates the meshing of the internal gear ring 130 and the gear set 120. It is understood that when the drive motor 110 operates, it will drive the gear set 120 to rotate, thereby driving the internal gear ring 130 to rotate. To achieve the rotation of the internal gear ring 130, a bearing 132 is sleeved on the outer side of the internal gear ring 130. The inner ring of the bearing 132 contacts the internal gear ring 130 and can rotate with the rotation of the internal gear ring 130, while the outer ring of the bearing 132 contacts the outer wall of the gearbox lower cover 165. Thus, along the radial direction of the abdominal massager, the internal gear ring 130 and the bearing 132 are sleeved between the outer wall of the receiving groove 166 and the outer wall of the gearbox lower cover 165; that is, the internal gear ring 130 and the bearing 132 are located within the mounting ring groove 151. Thus, compared to mounting the internal gear ring 130 on the outer side wall of the gearbox lower cover 165, this utility model is beneficial to reducing the radial dimension of the abdominal massage device, and further beneficial to reducing the volume of the abdominal massage device.

[0057] Along the axial direction of the abdominal massager, the upper end of the internal gear ring 130 extends radially outward to form a limiting flange 133. In one embodiment, the limiting flange 133 is arranged circumferentially along the internal gear ring 130. Thus, in the axial direction of the abdominal massager, both ends of the bearing 132 contact the limiting flange 133 and the lower housing respectively, thereby achieving axial positioning of the bearing 132 in the abdominal massager. Thus, through the arrangement of the receiving groove 166 and the mounting ring groove 151, the abdominal massager does not require an additional axial positioning component for the bearing 132, which simplifies the structure of the abdominal massager and contributes to its compact design.

[0058] Understandably, the lower shell 150 has a ring structure. When the upper shell 140 and the lower shell 150 are assembled, the inner toothed ring 130 can be exposed from the ring hole of the lower shell 150 to connect with the massage component 200.

[0059] Please see Figure 2 and Figure 3 In an embodiment of this utility model, a first rotating shaft 162, a second rotating shaft (not shown), and a second rotating shaft 163 are installed inside the gearbox 160. The gear set 120 includes a first-stage gear 121, a second-stage gear 122, a third-stage gear 123, and a fourth-stage gear 124 that mesh sequentially. The first-stage gear 121 is mounted on the output shaft of the drive motor 110. The second-stage gear 122 is mounted on the first rotating shaft 162. The third-stage gear 123 is mounted on the second rotating shaft. The fourth-stage gear 124 is mounted on the third rotating shaft 163 and meshes with the internal gear ring 130 through the meshing port 161. The first rotating shaft 162, the second rotating shaft, the third rotating shaft 163, and the output shaft of the drive motor 110 are arranged parallel to each other.

[0060] Specifically, in the solution shown in the figures of this utility model patent, the gear set 120 includes four stages of gears, specifically including a first stage gear 121, a second stage gear 122, a third stage gear 123, and a fourth stage gear 124 that mesh sequentially. The first stage gear 121 is mounted on the output shaft of the drive motor 110, and the first stage gear 121 and the output shaft of the drive motor 110 cannot rotate relative to each other, so that the first stage gear 121 transmits power as the output shaft of the drive motor 110 rotates. A first rotating shaft 162 and a second rotating shaft 163 are also fixed between the upper cover 164 and the lower cover 165 of the gearbox. The second stage gear 122 is mounted on the first rotating shaft 162, and the second stage gear 122 can rotate relative to the first rotating shaft 162, so that the second stage gear 122 can rotate as the first stage gear 121 rotates. The third-stage gear 123 is mounted on the second rotating shaft and can rotate relative to the second rotating shaft, so that the third-stage gear 123 can rotate along with the rotation of the second-stage gear 122. The fourth-stage gear 124 is mounted on the third rotating shaft 163 and can rotate relative to the third rotating shaft 163, so that the fourth-stage gear 124 can rotate along with the rotation of the third-stage gear 123. At the same time, the fourth-stage gear 124 also meshes with the internal gear ring 130 through the meshing port 161 to drive the internal gear ring 130 to rotate. Thus, the gear set 120 includes four stages of gears, which allows the drive motor 110 to be a small high-speed motor. The high-speed motor, after being reduced by four stages of gears, can meet the rotation requirements of the massage component 200. This helps to reduce the size of the drive motor 110, and thus the size of the abdominal massager, making the abdominal massager easier to carry.

[0061] Meanwhile, in this utility model, the first rotating shaft 162, the second rotating shaft, the third rotating shaft 163 and the output shaft of the drive motor 110 are arranged parallel to each other. Compared with the scheme in which the first rotating shaft 162, the second rotating shaft 163 and the output shaft of the drive motor 110 are arranged perpendicularly, this is beneficial to reducing the size of the abdominal massage device, which is conducive to the miniaturization of the abdominal massage device, and thus makes the abdominal massage device easier to carry.

[0062] Please see Figure 2 and Figure 3 In the embodiments of this utility model, the second-stage gear 122, the third-stage gear 123, and the fourth-stage gear 124 are all configured with double-layer teeth.

[0063] Specifically, the second-stage gear 122 includes coaxial second-stage gear one and second-stage gear two; the third-stage gear 123 includes coaxial third-stage gear one and third-stage gear two; and the fourth-stage gear 124 includes coaxial fourth-stage gear one and fourth-stage gear two. The first-stage gear 121 meshes with second-stage gear one, the second-stage gear two meshes with third-stage gear one, the third-stage gear two meshes with fourth-stage gear one, and the fourth-stage gear two meshes with the internal gear ring 130 through meshing port 161. This double-layer gear arrangement facilitates adjusting the gear ratio between each gear, thereby adjusting the speed ratio between the drive motor 110 and the turntable 210.

[0064] Please see Figure 4 In an embodiment of this utility model, the massage component 200 further includes a heating element 230, which is attached to the massage head 220.

[0065] Specifically, the turntable 210 includes an upper cover 211 and a lower cover 212 connected to each other. In one embodiment, the upper cover 211 and the lower cover 212 are detachably connected by a screw structure. A massage head 220 is mounted on the lower cover 212. More specifically, the lower cover 212 has mounting holes, and at least a portion of the massage head 220 extends out of the mounting holes between the upper cover 211 and the lower cover 212. In one embodiment, the massage assembly 200 further includes a heating element 230, which is attached to the massage head 220 to heat the massage head 220, thereby heating the abdomen and improving the massage function and effect.

[0066] In one embodiment, the massage assembly 200 further includes a light-emitting element 250. The light-emitting element 250 is located at the center of the plurality of massage heads 220. The light-emitting element 250 includes a lamp plate bracket 251 and a lamp plate 252. The lamp plate bracket 251 is located between the upper cover 211 and the lower cover 212 of the turntable, and the lamp plate 252 is mounted on the lamp plate bracket 251. Correspondingly, the lower cover 212 of the turntable has a hole for the lamp plate 252, through which the lamp plate bracket 251 protrudes. In one embodiment, a lamp plate 252 sealing gasket is also provided between the lamp plate bracket 251 and the lower cover 212 of the turntable. The lamp plate 252 sealing gasket improves the sealing performance between the light-emitting element 250 and the lower cover 212 of the turntable, and also helps to reduce the operating noise of the abdominal massager. In one embodiment, the light-emitting element 250 can emit infrared light to promote blood circulation and improve immunity. The wavelength of the light emitted by the light-emitting element 250 is not limited here.

[0067] Please see Figures 2 to 5 In an embodiment of this utility model, the main unit 100 includes a first circuit board 170 and a first conductive element electrically connected to the first circuit board 170. The first circuit board 170 is disposed on the side of the gearbox 160 facing the massage assembly 200, and the first conductive element protrudes from the lower shell 150. The massage assembly 200 includes a second circuit board 240 and a second conductive element electrically connected to the second circuit board. The second circuit board 240 is disposed on the side of the turntable 210 facing the main unit 100. One of the first conductive element and the second conductive element is configured as a conductive ring 241, and the other is configured as a conductive needle 171. As the turntable 210 rotates, the conductive needle 171 slides on the conductive ring 241 and is always in contact with the conductive ring 241.

[0068] Understandably, the massage assembly 200 includes a heating element 230 and a light-emitting element 250. To achieve heating by the heating element 230 and light emission by the light-emitting element 250, an electrical connection is required between the main unit 100 and the massage assembly 200. In the solution shown in the figures of this utility model, the main unit 100 is provided with a first circuit board 170. In one embodiment, the first circuit board 170 is fixed to the gearbox 160 by screws. Understandably, both the lower shell 150 and the inner gear ring 130 have annular structures, and the outer diameter of the inner gear ring 130 is smaller than the inner diameter of the lower shell 150, allowing the inner gear ring 130 to protrude from the annular hole of the lower shell 150. Simultaneously, the inner gear ring 130 also has an annular hole, allowing the first conductive element electrically connected to the first circuit board 170 to protrude from the annular hole of the inner gear ring 130 after the first circuit board 170 is fixed to the gearbox 160.

[0069] Understandably, the turntable cover 211 also has an annular structure, and the second circuit board 240 is disposed between the turntable cover 211 and the turntable lower cover 212. More specifically, the second circuit board 240 is disposed between the lamp board 252 and the turntable cover 211. In one embodiment, the second circuit board 240 is fixed to the turntable cover 211 by screws. At the same time, the second conductive element electrically connected to the second circuit board 240 can be exposed from the annular hole of the turntable cover 211; or, the position of the second conductive element corresponds to the position of the annular hole of the turntable cover 211, so that the first conductive element can be electrically connected to the second conductive element through the annular hole of the internal gear ring 130 and the annular hole of the turntable cover 211.

[0070] In the embodiment shown in the figures of this utility model, the first conductive element is configured as a conductive needle 171, and the second conductive element is configured as a conductive ring 241. The number, structure, and position of the conductive needles 171 and the conductive rings 241 correspond one-to-one. When the main unit 100 is connected to the massage assembly 200, the conductive needles 171 and the conductive rings 241 come into contact. When the drive motor 110 is working, the turntable 210 rotates with the internal gear ring 130, causing the second circuit board 240 to rotate accordingly. The conductive rings 241 rotate accordingly, causing the conductive rings 241 to slide relative to the conductive needles 171. During the sliding process, the conductive needles 171 and the conductive rings 241 remain in contact to ensure that the electrical connection between the conductive needles 171 and the conductive rings 241 is not interrupted, thereby providing power to the heating element 230 and the light-emitting element 250. In one embodiment, the first conductive element includes multiple conductive pins 171, and the second conductive element includes multiple conductive rings 241, with one conductive pin 171 corresponding to one conductive ring 241, to increase the electrical connection contact area of ​​the first circuit board 170 and the second circuit board 240, so as to avoid some conductive pins 171 not contacting the conductive rings 241 and thus not being able to conduct electricity, thereby ensuring the reliability of the electrical connection between the first circuit board 170 and the second circuit board 240.

[0071] In embodiments of this invention, multiple sets of conductive pins 171 are provided, and each set of conductive pins 171 can contact the conductive ring 241. It can be understood that in the scheme shown in the figures of this invention, the first circuit board 170 is provided with three sets of conductive pins 171, each set containing multiple conductive pins 171, and each set of conductive pins 171 can contact the conductive ring 241. This further increases the contact area between the conductive pins 171 and the conductive ring 241, and increases the electrical connection points between the first circuit board 170 and the second circuit board 240. This redundant arrangement improves the reliability of the electrical connection between the first circuit board 170 and the second circuit board 240.

[0075] Specifically, the internal gear ring 130 has a first connecting hole 131 on its end face facing the massage assembly 200, and the turntable cover 211 has a second connecting hole 213. Screws or bolts or other connecting components pass through the first connecting hole 131 and the second connecting hole 213, thereby connecting the internal gear ring 130 and the turntable 210 together. In one embodiment, the first connecting hole 131 is a blind hole to avoid the connecting component affecting the internal gear ring 130 and the gear set 120. In one embodiment, to improve the connection stability between the internal gear ring 130 and the turntable 210, multiple corresponding first connecting holes 131 and second connecting holes 213 are provided; the number, position, and shape of the first connecting holes 131 and the second connecting holes 213 are not limited here.
