[0040] Combine Figure 1 、 Figure 2 and Figure 3 The present application provides a handheld massager. The handheld massager includes a handle 100 and a massage mechanism 200. The massage mechanism 200 includes an insulating mounting member 210, a conductive connector 220, a conductive ball bearing 230, and a conductive massage member 240. The insulating mounting member 210 is fixedly mounted on the handle 100. The conductive connector 220 is mounted on the insulating mounting member 210. The conductive connector 220 is used to connect to a power source. The conductive massage member 240 is rotatably sleeved on the insulating mounting member 210. The conductive ball bearing 230 is rollably mounted on the insulating mounting member 210 and / or the conductive connector 220. The conductive ball bearing 230 is in rolling contact with the conductive connector 220 and the conductive massage member 240, respectively.

[0041] In this embodiment, current flows through the conductive connector 220 and the conductive balls 230 to the conductive massage member 240. The conductive massage member 240 rotates around the insulating mounting member 210, rolling into contact with the human body, providing both material massage and microcurrent therapy. The conductive balls 230 disposed between the conductive massage member 240 and the insulating mounting member 210 significantly reduce rotational resistance and wear of the conductive massage member 240, allowing the massage mechanism 200 to rotate more smoothly, resolving the technical issue of the awkward operation of existing handheld massagers. Furthermore, the smoothly rotating conductive massage member 240 facilitates the uniform conduction of the microcurrent, enhancing the uniformity and depth of the massage, and improving the comfort of the massage.

[0042] In this embodiment, the conductive ball 230 can be mounted in a rolling and position-limited manner on the insulating mounting member 210, or can be mounted in a rolling and position-limited manner on the conductive connector 220, or can be mounted in a rolling and position-limited manner on both the insulating mounting member 210 and the conductive connector 220, without limitation herein. For example, the insulating mounting member 210 has a first groove 211 for accommodating the conductive ball 230, which enables the conductive ball 230 to be mounted in a rolling and position-limited manner on the insulating mounting member 210, fully utilizing the radial direction of the insulating mounting member 210 to accommodate the conductive ball 230, facilitating the miniaturization of the massage mechanism 200, and providing greater support for the conductive ball 230 provided by the insulating mounting member 210, thereby facilitating the assembly stability of the conductive ball 230.

[0043] In some embodiments, combined Figure 3 and Figure 4 The insulating mounting part 210 has a first groove 211, which extends along the circumference of the insulating mounting part 210. A part of the conductive ball 230 is limited in the first groove 211, so that the conductive ball 230 is supported and limited in the axial direction of the insulating mounting part 210, ensuring the axial stability and reliability of the conductive ball 230 and the conductive massage part 240 during use. The conductive ball 230 and the first groove 211 do not need to be hard-connected, which simplifies assembly.

[0044] In addition, another part of the conductive ball 230 is exposed in the first groove 211. On the one hand, the first groove 211 does not need to wrap the entire conductive ball 230, which is conducive to the absolute size reduction design of the first groove 211. On the other hand, the exposed part of the conductive ball 230 can more conveniently roll in contact with the conductive connecting part 220 and the conductive massage part 240, and the conductive connecting part 220 and the conductive massage part 240 do not need to extend into the first groove 211 to roll in contact with the conductive ball 230.

[0045] Specifically, the bottom of the first groove 211 is the ball groove wall. The diameter of the sphere where the ball groove wall is located is larger than the diameter of the conductive ball 230. The conductive ball 230 abuts against the ball groove wall. The abutment points are mainly concentrated on the curved surface of the conductive ball 230, rather than the entire surface of the conductive ball 230, which reduces the contact area between the conductive ball 230 and the ball groove wall during rotation, thereby further reducing the wear and rolling resistance of the conductive ball 230.

[0046] Optionally, the diameter of the spheres in which the ball groove walls are located is 2 to 5 times the diameter of the conductive balls 230, thereby better confining the conductive balls 230 within the first groove 211 and reducing the swing range of the conductive balls 230 about the rotation axis 241 of the conductive massage element 240. If the diameter of the spheres in which the ball groove walls are located is less than 2 times the diameter of the conductive balls 230, the gap between the notch of the first groove 211 and the conductive balls 230 will be too small. This will, on the one hand, cause wear between the conductive balls 230 and the groove edge of the first groove 211 during rolling, and on the other hand, severely limit the swing flexibility of the conductive balls 230 about the rotation axis 241 of the conductive massage element 240, potentially affecting the smooth rolling of the conductive balls 230. If the diameter of the sphere where the ball groove wall is located is greater than 5 times the diameter of the conductive ball 230, the first groove 211 will weaken the support and limitation of the conductive ball 230 on the rotation axis 241 of the conductive massage part 240, affecting the rolling position stability of the conductive ball 230, and may generate noise and vibration due to rolling.

[0047] Optionally, the radius of the conductive ball 230 is greater than the depth of the first groove 211 to prevent the conductive ball 230 from being excessively located within the first groove 211, thereby preventing excessive friction and wear caused by excessive contact and improving the rolling flexibility of the conductive ball 230. For example, the radius of the conductive ball 230 is 1.2 to 2 times the depth of the first groove 211, so that the conductive ball 230 can maintain appropriate clearance and freedom during rolling, thereby ensuring smooth and stable rolling.

[0048] In some embodiments, combined Figure 4 and Figure 6 The conductive connector 220 covers the notch of the first groove 211 and has a limiting hole 221. The conductive ball 230 is exposed outside the conductive connector 220 through the limiting hole 221. The limiting hole 221 limits the circumferential position of the conductive ball 230, restricting the positional stability of the conductive ball 230 in the circumferential direction of the insulating mounting member 210. This allows the conductive ball 230 to maintain a stable position in rolling contact with the conductive massage member 240, thereby improving the conductive stability and rotational smoothness of the conductive massage member 240.

[0049] Specifically, the clearance between the limiting hole 221 and the conductive ball 230 facilitates the smooth rolling of the conductive ball 230. Furthermore, the rotation of the conductive massage element 240 about its rotation axis 241 drives the conductive ball 230 to rotate about its rotation axis 241, allowing the conductive ball 230 to maintain stable circumferential conductive contact with the wall of the limiting hole 221, thereby ensuring conductive stability. Optionally, the diameter of the limiting hole 221 is 1.01 to 1.5 times the diameter of the conductive ball 230, ensuring both rolling flexibility and circumferential positioning of the conductive ball 230, thereby ensuring circumferential position stability.

[0050] It can be understood that in other embodiments, the diameter of the limiting hole 221 is less than or equal to the diameter of the conductive ball 230, and the conductive ball 230 is only allowed to partially pass through the limiting hole 221, but not completely pass through the limiting hole 221, thereby enhancing the circumferential and radial limiting of the conductive ball 230, and at the same time achieving the rolling limitation of the conductive ball 230 in the limiting hole 221.

[0051] Specifically, combined Figure 6 and Figure 7 The limiting hole 221 is open on one side close to the handle 100 so that the conductive ball 230 can be sleeved on the limiting hole 221 through the opening, thereby simplifying the assembly operation.

[0052] It should be noted that the number of the limiting holes 221 is greater than or equal to the number of the conductive balls 230. In other words, each limiting hole 221 may be provided with a conductive ball 230, or some limiting holes 221 may be provided with a conductive ball 230, while some limiting holes 221 may not contain a conductive ball 230. This is not specifically limited here. The user can flexibly adjust the number of the conductive balls 230 according to the required rotation speed of the conductive massage part 240. For example, when it is necessary to further reduce the rotational resistance of the conductive massage part 240, the number of the conductive balls 230 can be increased, or even each limiting hole 221 can be provided with a conductive ball 230. For another example, when it is necessary for the conductive massage part 240 to gently massage the human body, the number of the conductive balls 230 can be reduced, and some limiting holes 221 may not contain conductive balls 230.

[0053] In some embodiments, combined Figure 4 、 Figure 6 and Figure 7The insulating mounting member 210 has a first stop portion 212, and the conductive connector 220 is sleeved on the outside of the insulating mounting member 210 to achieve radial position stability of the conductive connector 220 in the insulating mounting member 210. The conductive connector 220 abuts against the first stop portion 212 to limit the conductive connector 220 from moving along the axial direction of the insulating mounting member 210 toward the handle 100, thereby providing support and position stability for the conductive connector 220 in the axial direction of the insulating mounting member 210.

[0054] Specifically, combined Figure 4 The insulating mounting member 210 is provided with first stop portions 212 on the upper and lower sides of the conductive ball 230, that is, on the upper and lower sides of the first groove 211. The lower end surface of the conductive connecting member 220 abuts against the first stop portion 212 located on the lower side. The top end of the conductive connecting member 220 is provided with a flange 225 abutting against the first stop portion 212 located on the upper side, thereby enhancing the axial support force and stability of the conductive connecting member 220.

[0055] Optionally, the end of the flange 225 abuts against the outer wall of the insulating mounting member 210 to achieve radial fixation of the conductive connector 220 on the insulating mounting member 210 .

[0056] Specifically, the first stop portion 212 is a stop step surface, the normal of which is consistent with the rotation axis 241 of the conductive massage part 240. The conductive connector 220 is restricted by the obstruction of the stop step surface and cannot continue to move along the axial direction of the insulating mounting part 210 toward the handle 100.

[0057] In some embodiments, combined Figure 6 and Figure 7 One of the insulating mounting member 210 and the conductive connector 220 has a first limiting groove 222, and the other of the insulating mounting member 210 and the conductive connector 220 has a first limiting portion 213. The first limiting portion 213 is engaged with the first limiting groove 222 to limit the axial rotation of the conductive connector 220 around the insulating mounting member 210, thereby realizing the circumferential limitation of the conductive connector 220 on the insulating mounting member 210, improving the circumferential stability of the conductive connector 220, and preventing the conductive connector 220 from rotating with the conductive mounting member around its rotation axis 241. On the one hand, it reduces the rotational load and rotational resistance, and improves the rotation smoothness of the conductive massage member 240. On the other hand, the position of the conductive connector 220 is stable, which is conducive to stable conduction with the power supply and ensures the stability of current transmission.

[0058] Specifically, see Figure 6 and Figure 7The insulating mounting member 210 has a first limiting portion 213, and the conductive connector 220 has a first limiting groove 222. Optionally, the flange 225 of the conductive connector 220 has the first limiting groove 222, and the first stopper 212 located on the upper side is provided with the first limiting portion 213. Optionally, the first limiting portion 213 is provided protruding from the outer periphery of the insulating mounting member 210, and the bottom of the first limiting portion 213 abuts against the bottom of the first limiting groove 222, thereby limiting the conductive connector 220 from moving along the axial direction of the insulating mounting member 210 in a direction away from the handle 100. Furthermore, when the first stop portion 212 has restricted the conductive connector 220 from moving in the axial direction of the insulating mounting member 210 toward the handle 100, the conductive connector 220 is fixed in the axial position. Simultaneously, due to the sleeve of the insulating mounting member 210, the radial position is fixed. Due to the engagement of the first limiting portion 213 and the first limiting groove 222, the circumferential position is fixed, further enhancing the positional stability of the conductive connector 220. It is understood that in other embodiments, the conductive connector 220 may have the first limiting portion 213 and the insulating mounting member 210 may have the first limiting groove 222, which are not specifically limited herein.

[0059] Specifically, the first limiting portion 213 may be a limiting block or a limiting rib, which is not specifically limited here.

[0060] Specifically, there are multiple first limiting grooves 222 , which are distributed at intervals along the circumference of the insulating mounting member 210 , thereby improving the uniformity and strength of the circumferential limiting.

[0061] In some embodiments, combined Figure 6 and Figure 7 The insulating mounting member 210 has a first connection hole 216 , and the conductive connecting member 220 has a second connection hole 224 . The first connection hole 216 and the second connection hole 224 are used for the same fastener to pass through and connect, thereby achieving fixed installation of the conductive connecting member 220 on the insulating mounting member 210 .

[0062] In some embodiments, combined Figure 6 and Figure 7 The insulating mounting member 210 has a second limiting groove 215, which is located on the side of the conductive ball 230 near the handle 100. The conductive connector 220 is connected to a connecting strip 223, which is embedded in the second limiting groove 215. The connecting strip 223 is positioned against the groove wall of the second limiting groove 215 along the circumferential side wall of the insulating mounting member 210, thereby enhancing the circumferential position stability of the conductive connector 220.

[0063] Optionally, the second limiting groove 215 and the first limiting portion 213 are respectively located on both sides of the first groove 211 in the axial direction, so that the conductive connector 220 is circumferentially limited on both the upper and lower sides of the first groove 211.

[0064] Optionally, the bottom of the second limiting groove 215 has a first connection hole 216, and the connecting bar 223 has a second connection hole 224. A fastener is inserted through the first connection hole 216 and the second connection hole 224 to securely install the connecting bar 223 within the second limiting groove 215. Furthermore, the connecting bar 223 is connected to the power source via a conductive transmission member 260. The conductive transmission member 260 has a third connection hole 261. The first connection hole 216, the second connection hole 224, and the third connection hole 261 are used to be inserted and connected by the same fastener, thereby achieving a fixed connection between the three, reducing the number of connection operations and the number of holes to be opened.

[0065] In some embodiments, combined Figure 4 The inner side of the conductive massage part 240 has a second groove 242, and the second groove 242 is arranged around the rotation axis 241 of the conductive massage part 240. A part of the conductive ball 230 is limited in the second groove 242. On the first aspect, the conductive ball 230 is supported and limited on the rotation axis 241 of the conductive massage part 240. On the second aspect, it is conducive to stable electrical transmission between the conductive ball 230 and the conductive massage part 240. On the third aspect, the conductive ball 230 cooperates with the limiting position of the second groove 242, so that the conductive massage part 240 can rotate stably along the trajectory direction of the second groove 242 without deviating from the predetermined trajectory.

[0066] Specifically, the bottom of the second groove 242 is curved, and the diameter of the sphere within the curved groove bottom is 4 to 10 times the diameter of the conductive ball 230. This weakens the axial restraint between the conductive ball 230 and the second groove 242, thereby improving the rotational resistance and flexibility of the conductive massage element 240. If the diameter of the sphere within the curved groove bottom is less than 4 times the diameter of the conductive ball 230, the contact area between the curved groove bottom and the conductive ball 230 increases, increasing the rotational resistance of the conductive massage element 240. If the diameter of the sphere within the curved groove bottom is greater than 10 times the diameter of the conductive ball 230, the second groove 242 weakens the support and restraint of the conductive ball 230 on the rotation axis 241 of the conductive massage element 240, potentially making the rotation trajectory of the conductive massage element 240 unstable, and potentially generating noise and vibration due to rolling.

[0067] Optionally, the radius of the conductive ball 230 is 3 to 8 times the depth of the second groove 242, so that the conductive ball 230 can maintain appropriate clearance and freedom when rolling, thereby ensuring smoothness and stability of rolling.

[0068] Specifically, the roughness of at least one of the conductive ball 230 and the groove wall of the second groove 242 is less than or equal to 1 micron, which can effectively reduce the friction between the conductive ball 230 and the groove wall of the second groove 242 .

[0069] In some embodiments, combined Figure 4 There is a gap between the conductive connecting member 220 and the conductive massage member 240 , and the conductive connecting member 220 and the conductive massage member 240 are not in direct contact, which reduces friction and wear between the two and helps to reduce the rotation resistance of the conductive massage member 240 .

[0070] In some embodiments, combined Figure 3 and Figure 8 The conductive massage member 240 includes a conductive sleeve 243, an elastic arm 244, and a massage protrusion 245. The conductive sleeve 243 is rotatably mounted on the insulating mounting member 210, thereby limiting the conductive massage member 240 in the radial direction of the conductive sleeve 243. The conductive sleeve 243 has a first through hole 2431. One end of the elastic arm 244 is connected to the hole wall of the first through hole 2431. The other end of the elastic arm 244 is spaced apart from the conductive sleeve 243 and connected to the massage protrusion 245. When the massage protrusion 245 presses against the human body, the elastic arm 244 can bend and deform according to the shape and force of the contact surface of the human body. The massage protrusion 245 can achieve elastic expansion and contraction, ensuring uniform distribution of massage force and reducing localized pressure, thereby improving massage comfort.

[0071] Among them, the design of the elastic arm 244 allows the massage protrusion 245 to achieve a certain degree of flexible deformation while maintaining a certain rigidity, thereby being able to simulate more types of massage techniques (such as kneading, tapping, vibration, etc.) and improving the massage effect.

[0072] In one embodiment, the conductive sleeve 243 has a deformation gap 2433, which extends along the axial direction of the conductive sleeve 243, so that the conductive sleeve 243 is in a non-closed ring shape. The non-closed ring structure provides the conductive sleeve 243 with a larger elastic deformation space. During the massage process, when the massage protrusion 245 contacts the human body and is subjected to pressure, the pressure is transmitted to the conductive sleeve 243, and the conductive sleeve 243 can absorb and disperse this pressure through elastic deformation, thereby reducing direct impact and discomfort on the human body. At the same time, by improving the adaptability and elastic deformation ability of the conductive sleeve 243, it helps to ensure that the conductive sleeve 243 maintains a good contact state with the conductive ball 230 during rotation and deformation, thereby optimizing the conductive performance of the massage mechanism 200.

[0073] Specifically, combined Figure 8The deformed gap 2433 includes a first linear gap 2434, an arc-shaped gap 2435, and a second linear gap 2436. The first linear gap 2434, the arc-shaped gap 2435, and the second linear gap 2436 are sequentially connected and distributed along the rotation axis 241 of the conductive massage element 240. The deformed gap 2433 is zigzag, combining linear gaps with arc-shaped gaps 2435. This allows the conductive sleeve 243 to be more evenly distributed across the structure when subjected to external forces, avoiding stress concentration that could result from a single linear gap, thereby improving the structural strength and rigidity of the conductive sleeve 243. Furthermore, the deformed gap 2433 is non-linear, preventing the conductive sleeve 243 from being misaligned and deformed along the rotation axis 241, which could cause the conductive ball 230 to become stuck.

[0074] Furthermore, in the structures on both sides of the arc-shaped gap 2435, one side is concave and the other side is convex, and the concave and convex are aligned, which can achieve better alignment and limiting, and reduce the risk of the structures on both sides of the deformation gap 2433 being misaligned upward and downward.

[0075] Specifically, there are two groups of massage protrusions 245, which are spaced apart along the rotation axis 241 and located on the upper and lower sides of the conductive ball 230. This is beneficial to balancing the force on the conductive ball 230 during rotation, reducing the wear of the conductive ball 230 or the deflection of the conductive massage part 240 due to uneven force, and at the same time providing more comprehensive massage coverage.

[0076] Optionally, each group of massage protrusions 245 has a plurality of massage protrusions 245, and the plurality of massage protrusions 245 are spaced apart around the rotation axis 241. This more meticulously covers the upper massage area and the lower massage area, providing more precise and more massage points.

[0077] Optionally, the size of one set of massage protrusions 245 located on the conductive ball bearings 230 away from the handle 100 is larger than the size of the other set of massage protrusions 245. When the user grips the handle 100, using their wrist as a rotational support, the massage protrusions 245 located farther from the handle 100 have a larger lever arm. By increasing the size of the distal massage protrusions 245, they provide a stronger massage, suitable for areas requiring deep relaxation. Meanwhile, the massage protrusions 245 located closer to the handle 100 have a smaller lever arm, and by reducing the size of the proximal massage protrusions 245, they are suitable for sensitive areas or those requiring a gentler massage. This allows the massage mechanism 200 to flexibly select massage protrusions 245 in different locations to provide massages tailored to the needs of different areas and individuals.

[0078] In addition, the massage mechanism 200 has a large space around the end away from the handle 100, which is conducive to the selection of larger massage protrusions 245 and facilitates large-angle massage movements, while the space near the end of the handle 100 is narrow, which is conducive to the selection of small massage protrusions 245.

[0079] Specifically, at least some of the first through holes 2431 have notches 2432 on the side away from the conductive ball 230. The design of the notches 2432 increases the deformation capacity of the hole wall of the corresponding first through hole 2431, thereby improving the massage amplitude of the massage protrusions 245 located within the first through hole 2431. Optionally, all of the first through holes 2431 located on the upper side have notches 2432, increasing the elastic deformation space of the massage protrusions 245 located on the upper side, facilitating the massage protrusions 245 located on the upper side to apply strong elastic pressure. Optionally, one of the two adjacent first through holes 2431 located on the lower side has a notch 2432 to increase the elastic deformation capacity of the massage protrusions 245 in this position, while the other first through hole 2431 does not have a notch 2432, thereby ensuring the structural strength of the conductive massage element 240.

[0080] In one embodiment, the combination Figure 8 The conductive massage element 240 is integrally formed, comprising the conductive sleeve 243, elastic arm 244, and massage protrusion 245. This reduces assembly operations and eliminates assembly errors, improving positional consistency and facilitating assembly with the conductive ball 230. The integrally formed conductive massage element 240 exhibits high precision and eliminates gaps in the connection, which helps reduce roughness, minimize friction between the conductive sleeve 243 and the conductive ball 230, and enhance smooth rotation.

[0081] In some embodiments, combined Figure 2 、 Figure 3 and Figure 5 The massage mechanism 200 also includes an insulating housing 250, which is fixedly mounted on the outside of the conductive sleeve 243. The insulating housing 250 has a second through-hole 251, through which the massage protrusions 245 are exposed on the outside of the insulating housing 250. The insulating housing 250 isolates the conductive sleeve 243 from the external environment, effectively preventing the current from accidentally contacting the human body. It also protects the conductive sleeve 243 and other internal components from moisture, dust, dirt, and other substances in the external environment. The insulating housing 250 supports the conductive massage element 240, preventing the connection structure on the conductive massage element 240 and dynamic friction with the insulating mounting member 210, thereby preventing damage to the structural strength and elastic properties of the conductive massage element 240. Simultaneously, the massage protrusions 245 can press the human body through the second through-hole 251. By controlling the contact position of the massage protrusions 245, a targeted and controllable massage operation is achieved.

[0082] In one embodiment, both ends of the insulating housing 250 are respectively constrained by the insulating mounting member 210, achieving positional stability about the rotation axis 241. Specifically, a second limiting portion 252 is provided at the end of the insulating housing 250 away from the handle 100. The second limiting portion 252 abuts against the insulating mounting member 210, restricting movement of the insulating housing 250 away from the handle 100, thereby achieving one-way axial positioning of the insulating housing 250 and providing rotational support for the insulating housing 250 and the conductive massage member 240. Optionally, the roughness of the second limiting portion 252 is less than or equal to 1 micron, effectively reducing friction between the insulating housing 250 and the insulating mounting member 210.

[0083] Specifically, a third limiting portion 253 is provided at one end of the insulating shell 250 close to the handle 100. The third limiting portion 253 abuts against the insulating mounting member 210 to limit the movement of the insulating shell 250 toward the handle 100, thereby realizing one-way limiting of the insulating shell 250 in the axial direction and providing rotational support for the insulating shell 250 and the conductive massage member 240.

[0084] Optionally, the roughness of the third limiting portion 253 is less than or equal to 1 micron, which can effectively reduce the friction between the insulating housing 250 and the insulating mounting member 210. Optionally, the insulating mounting member 210 is provided with a first flange 214 at the end near the handle 100, and the third limiting portion 253 is rotatably supported on the first flange 214.

[0085] In one embodiment, the insulating housing 250 has an escape plane 254, and the second through hole 251 is disposed through the escape plane 254. The escape plane 254 allows the massage mechanism 200 to better conform to the human body. At the same time, the massage protrusions 245 are more prominent relative to the escape plane 254, making it easier to press the human body and providing greater elasticity and flexibility, allowing for massage operations of varying amplitudes.

[0086] In some embodiments, combined Figure 3 、 Figure 5 and Figure 7 The insulating mounting member 210 includes an intermediate retainer 217 and an end cap 218. One end of the intermediate retainer 217 is fixedly connected to the handle 100, and the other end of the intermediate retainer 217 is detachably connected to the end cap 218. The detachable connection of the end cap 218 facilitates the installation of the insulating housing 250 or the conductive massage element 240 before installing the end cap 218, thereby achieving axial positioning of the insulating housing 250 or the conductive massage element 240 and simplifying assembly and maintenance operations.

[0087] Specifically, the end cover 218 is provided with a hook 2181, and the end of the intermediate retaining frame 217 away from the handle 100 is provided with a slot 2171. The hook 2181 can be detachably installed in the slot 2171 without the need for additional tools, thereby simplifying the disassembly and assembly operations.

[0088] Specifically, the end cap 218 is provided with a guide block 2182, and the end of the intermediate retainer 217 away from the handle 100 is provided with a guide groove 2172. The end cap 218 slides into the guide groove 2172 along with the guide block 2182 to achieve positioning and assembly on the intermediate retainer 217. Optionally, the guide blocks 2182 and the hooks 2181 are alternately spaced along the circumference of the end cap 218.

[0089] In some embodiments, combined Figure 7 The insulating mounting part 210 is provided with reinforcing ribs 219 inside, which can increase the strength of the insulating mounting part 210, so that the insulating mounting part 210 provides good support for the conductive massage part 240 and the insulating shell 250. At the same time, during the massage process, the insulating mounting part 210 is subjected to force without deformation.

[0090] In some embodiments, combined Figure 1 、 Figure 9 and Figure 10 The handle 100 includes a handle housing 110 and a circuit board 120. The power source is a battery 130. The circuit board 120 and battery 130 are installed within the handle housing 110. The circuit board 120 is electrically connected to the battery 130 and the conductive connector 220, respectively. The circuit board 120 distributes the power from the battery 130 to the conductive connector 220, which in turn transmits it to the conductive massage element 240, achieving microcurrent massage. The battery 130 can provide power to the conductive massage element 240 anytime and anywhere, expanding the range of uses for the handheld massager.

[0091] In one embodiment, combined Figure 7 and Figure 9 The shell includes a gripping portion 111 and two connecting branches 112 . The two connecting branches 112 are arranged at an angle and one end close to the other is connected to the same end of the gripping portion 111 . Each connecting branch 112 is provided with a massage mechanism 200 .

[0092] Specifically, the first massage mechanism 200 is connected to the positive pole of the power supply through the first connection branch 112, and the second massage mechanism 200 is connected to the negative pole of the power supply through the second connection branch 112. The two massage mechanisms 200 are in contact with the human body respectively to form a microcurrent loop.

[0093] Specifically, the connecting branch 112 has a fourth connecting hole 113, and the insulating mounting member 210 has a fifth connecting hole 2173 that is connected to and cooperates with the fourth connecting hole 113. Fasteners are detachably provided through the fourth connecting hole 113 and the fifth connecting hole 2173, enabling the massage mechanism 200 to be quickly assembled to the handle 100.

[0094] Specifically, connecting branch 112 is semi-shell-shaped, and the end of insulating mounting member 210 is provided with a connecting piece 2174. Connecting piece 2174 and connecting branch 112 are fitted together to form a cylindrical shape, thereby increasing the connection area. Optionally, connecting branch 112 is provided with a second flange 114. The second flange 114 of connecting branch 112 and the first flange 214 of connecting piece 2174 are combined to form an annular flange, which is used to support the rotation of insulating housing 250.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
