[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] A waterproof and adjustable micro-current massager according to a preferred embodiment of the present invention; Figure 1-2 As shown, the device comprises a main unit 11 and a microcurrent massage head 15 disposed at the lower end of the main unit. The lower end of the main unit also comprises a charging base 10 for powering the main unit, which is connected to a charging cable 14 for charging the main unit. The main unit 11 comprises an upper shell 111 and a bottom shell 110. The upper shell and the bottom shell are detachably connected by a snap or by screw fastening. The microcurrent massage head is detachably connected to the lower end of the bottom shell for easy replacement of the microcurrent massage head. A hand grip 112 is provided at the upper end of the bottom shell. By gripping the hand grip, the massager can be operated for massage. The microcurrent massage head can activate collagen deep in the facial skin using electric current stimulation, making it more delicate and smooth. At the same time, combined with hand movements, it can lift and tighten the facial skin.

[0039] Specifically, such as Figure 3 As shown, the main unit 11 is provided with a control panel 19 and a battery 17 connected to the control panel. The battery and the control panel are electrically connected. The upper shell is also provided with a heat dissipation hole 13 at the corresponding position of the control panel to facilitate heat dissipation from the control panel through the heat dissipation hole. The end of the handle 112 is provided with a light panel 18 and a knob assembly 12. The knob assembly and the light panel are both electrically connected to the control panel. When the massager is operating, the light panel illuminates to observe the operating status, and the operating status of the massager can be adjusted by rotating the knob assembly. To facilitate battery charging, the control panel is also provided with a charging port 16. A light guide 21 is provided at the heat dissipation hole. When the charging port is connected to the charging cable to charge the main unit, the light guide illuminates to observe the charging status. The lower end of the bottom shell 110 is provided with a plug-in portion 113. The plug-in portion is connected to the microcurrent massage head 15 to enable the massager to operate. Since the microcurrent massage head 15 is detachably connected to the plug-in portion, the same main unit can be used and replaced with different microcurrent massage heads for more convenient use.

[0040] Furthermore, if Figure 4-9As shown, the microcurrent assembly includes a microcurrent rear housing 150 and a microcurrent front housing 151. A microcurrent board 153 and a pogo pin male connector 152 connected to the microcurrent board are located within the front and rear housings. The pogo pin male connector partially extends through the microcurrent rear housing. The connector 113 includes four sets of ribs 1130 disposed on the bottom of the base housing. A gap 1131 is left between each set of ribs. Each set of ribs has a notch 1132 formed near the gap. The notch is formed by the ribs toward the base housing, forming an L-shaped slot 1137 with the gap, resulting in four sets of L-shaped slots. A first slot 1500 is provided corresponding to the rib 1130 on the side where the microcurrent rear shell is connected to the main unit. When the rib is inserted into the first slot, the stop block is located in the gap, and a stop block 1503 is provided on the first slot. Insert the rib into the first slot and rotate the microcurrent component relative to the main unit so that the gap is placed under the stop block, thereby forming a clamping effect between the L-shaped slot and the stop block. At this time, the microcurrent massage head cannot move in the direction perpendicular to the bottom shell.

[0041] Furthermore, if Figure 4-9 As shown, the rib 1130 is also provided with a locking groove 1133. A first locking block 1501 is provided on the microcurrent rear shell corresponding to the locking groove. The first locking block should be able to undergo a certain deformation and then recover after deformation. A protrusion 1502 is provided on the first locking block corresponding to the locking groove. When the rib is inserted into the first slot, an extrusion force is generated on the first locking block, causing the first locking block to undergo a certain deformation. After insertion, when the notch 1132 is placed below the stop block 1503 during rotation, the first locking block recovers its deformation, and the protrusion is located in the locking groove to achieve locking. At the same time, a crisp sound is emitted when locking. To facilitate the removal of the locked microcurrent massage head, the two ends of the locking groove should be provided with arc-shaped connecting surfaces to reduce resistance during rotation. The microcurrent rear shell is also provided with an anti-fouling groove 1504, and an anti-fouling portion 1134 is provided in the plug-in portion corresponding to the anti-fouling groove. The microcurrent massage head can only be inserted into the first plug-in portion when the anti-fouling portion corresponds to the anti-fouling groove. At the same time, the length of the anti-fouling groove is greater than the length of the anti-fouling portion, so that the anti-fouling groove also limits the rotational travel of the microcurrent massage head during installation. Indicator marks 1100 are provided on the bottom shell, and the locking and unlocking directions can be observed through the indicator marks. The microcurrent front shell 151 is provided with an anti-slip portion 1510 to facilitate the use of rotational force on the microcurrent massage head during rotation. To facilitate the host to power the microcurrent massage head, an electrode socket 1136 is provided on the plug-in portion. When the microcurrent massage head is locked with the plug-in portion, the spring pin male socket 152 is placed in the electrode socket and connected to the host for power.

[0042] Furthermore, if Figure 5 and Figure 9-10As shown, a boss 1511 is provided on one side of the microcurrent front shell 151, a concave accommodating cavity 15110 is provided in the middle of the boss, a microcurrent hole 15111 is provided in the accommodating cavity which passes through the microcurrent front shell, a microcurrent lens 155 is provided in the accommodating cavity, and the microcurrent emitted by the components on the microcurrent board enters the accommodating cavity through the microcurrent hole, and diffuses under the action of the microcurrent lens to act on the face for massage. The boss 1511 is higher than the surface of the microcurrent front shell, and a recessed groove 1512 is provided on the inner side of the outer edge of the microcurrent front shell. A skin contact ring 154 is provided in the space between the recessed groove and the boss. An outer convex ring 1540 is provided on the skin contact ring corresponding to the recessed groove, and an inner convex ring 1541 is provided corresponding to the boss. The outer wall 15410 of the inner convex ring contacts the outer wall 15112 of the boss, and the height of the boss is the same as that of the skin contact ring. After the inner convex ring is connected to the recessed groove and the outer convex ring contacts the outer wall of the boss, the skin contact ring is connected to the microcurrent front shell via screws, thereby achieving waterproofing without the need for a sealing ring between the skin contact ring and the microcurrent front shell. When using the microcurrent massage head for massage, the skin contact ring and the microcurrent lens both come into contact with the skin. The microcurrent in the microcurrent lens activates collagen deep in the facial skin, making it more delicate and smooth. At the same time, the skin contact ring squeezes the skin, lifting and tightening the facial skin, making the massage head waterproof while also achieving a massage effect.

[0043] Furthermore, if Figure 11 As shown, the knob assembly 12 includes a middle ring fixing ring 124 connected to the upper shell by a snap fastener, the light panel is arranged in the middle ring fixing ring, and a button control panel 123 is arranged on the middle ring fixing ring, and a knob 121 is arranged above the button control panel, an upper ring fixing ring 122 is arranged between the knob and the button control panel, and a knob cover 120 is provided on the knob outer shell. By turning the knob to adjust the button control panel, the output signal of the control panel is changed to adjust the working mode of the massager.

[0044] Furthermore, if Figure 12-16As shown, the knob cover 120 is sleeved on the outside of the knob, and four groups of connecting holes 1210 are set on the knob. Connecting posts 1201 are set corresponding to the connecting holes in the knob cover. The connecting posts are inserted into the connecting holes to make the knob rotate synchronously with the knob cover. A switch button 1230 is provided on the upper surface of the button control panel 123, and the massager is turned on or off by the switch button. In order to facilitate the start or shut down of the massager, an elastic pressing portion 1213 is provided on the knob corresponding to the switch button. At the same time, an elastic portion 1200 is also provided on the knob cover. When a certain force is applied to the elastic portion, the elastic portion is deformed so that the elastic pressing portion moves toward the switch button and after contact, the massager can be turned on by pressing the switch button. The elastic pressing portion 1213 includes a button contact portion 12131 and two groups of elastic connecting ears 12130 connecting the button contact portion 12131. When the elastic portion is subjected to force, the button contact portion moves toward the switch button and drives the elastic connecting ears to deform. After the force on the elastic portion disappears, the elastic connecting ears drive the button contact portion to reset, and the switch button action is completed. In order to avoid the massager being turned on due to accidental pressure on the elastic part during transportation, an upper ring fixing ring 122 is provided between the button control panel and the knob, and four groups of locking feet 1211 are provided inside the knob. The middle part of the upper ring fixing ring corresponds to the through hole provided with the elastic pressing part, and an inner retaining ring 1220 is provided around the through hole. The locking feet are placed at the inner retaining ring. A certain force needs to be applied to the elastic part to enable the elastic pressing part to pass through the through hole and thus apply force to the button switch.

[0045] Furthermore, if Figure 13-16 As shown, to facilitate adjusting the massager's intensity via the knob, an adjustment dial 1232 is located at the bottom of the key control panel. The control panel adjusts the massager's output state by changing the dial's signal. Rotating teeth 1212 are located around the dial, and corresponding teeth 1212 are located on the inner surface of the knob. Turning the knob changes the position of the adjustment dial, and the creaking sound between the teeth makes the adjustment more noticeable. The middle ring 124 is equipped with two sets of stoppers 1240, and the key control panel has corresponding stopper holes 1231 to prevent the key control panel from rotating while only the adjustment dial rotates. The lower end of the upper ring 122 is also equipped with a connecting post 1201, and the key control panel has corresponding connecting holes to connect the upper ring to the key control panel. The upper ring also has outwardly protruding fixing feet 1221, and the middle ring has corresponding fixing feet with fixing slots 1241, preventing the upper ring from rotating with the knob. Two sets of lamp board fixing holes 1242 are provided in the middle ring fixing circle, the lamp board is fixed in the hole, and a clamping hole 1243 is provided at the lower end. A corresponding buckle is provided in the upper shell to detachably connect the knob assembly to the upper shell.

[0046] Furthermore, if Figure 17-18As shown, the charging stand 10 includes a charging stand top cover 100 and a charging stand bottom cover 102 disposed below the charging stand top cover. A counterweight 101 is disposed between the charging stand top cover and the charging stand bottom cover to increase the weight of the charging stand. A host cavity 1000 is disposed within the charging stand top cover, into which the host can be placed. A cable clamping hole 1001 is disposed on the peripheral wall of the charging stand, into which the charging cable is placed. A magnetic head 140 is disposed at the end of the charging cable, which is used for magnetic charging, making it more convenient. A through hole 1002 is disposed within the host cavity, the radius of which is larger than the maximum radius of the microcurrent massage head, making it convenient for the host with the massage head installed to be directly charged. The massage head can also be removed for charging.
