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.

[0032] like Figures 1 to 6 As shown, the present invention provides an earphone type transcranial microcurrent stimulation device, comprising a device body, a protective shell 1 is arranged on the surface of the device body, a fixing rod is fixedly installed on the top of the front side of the protective shell 1, a rotating rod is rotatably connected to the surface of the fixed rod, a protective shell 2 is fixedly installed on the top of the rotating rod, and a connecting block is fixedly installed on the left end of the protective shell 2;

[0033] The rear end of the device body is plugged with a plug, the rear end of the plug is provided with a connecting wire, and the other end of the connecting wire is provided with the earphone body;

[0034] A limiting mechanism is arranged at the left end of the protective shell one. The limiting mechanism includes a fixed shell, which is fixedly connected to the left end of the protective shell one. A spring one is fixedly installed at the front end inside the fixed shell, a moving block is fixedly installed at the rear end of the spring one, an insertion rod is fixedly installed at the rear end of the moving block, a mounting block is fixedly installed at the left end of the protective shell one, a hinged rod is hinged at the left end of the mounting block, a connecting plate is fixedly installed at the top end of the surface of the hinged rod, and a protrusion located inside the connecting plate is fixedly installed at the left end of the moving block.

[0035] The above scheme is adopted: the operator inserts the plug into the rear end of the device body, and then inserts the earphone body into the ear, then the surface of the earphone body will be in close contact with the user's auricle, then the hinge rod can be pushed to rotate, and then the hinge rod will drive the connecting plate to rotate, when the connecting plate rotates, the protrusion will move inside the connecting plate, and then the protrusion will move forward, and then the protrusion will drive the moving block to move forward, when the moving block moves, the moving block will squeeze the spring 1, and then the moving block will drive the plug rod away from the inside of the connecting block, and then the protective shell 2 can be rotated to make the button at the bottom of the device body appear, and then the button at the top of the device body can be pressed, and then a microcurrent will be generated inside the device body, and then the microcurrent will pass through the connecting line and the earphone body, and then the microcurrent will stimulate the user's brain, and then the microcurrent stimulation treatment will be performed;

[0036] After the treatment is completed, the hinged rod can be rotated again to make the connecting plate drive the protrusion to move, and then the protective shell two can be rotated in the opposite direction to make the bottom end of the protective shell two contact with the top of the protective shell one, and then the plug rod will be aligned with the connecting block, and then the hinged rod can be loosened, and then the compressed spring one will push the moving block and the plug rod to move, and then the plug rod will enter the interior of the connecting block again, so that the protective shell two is fixed, and then the protective shell two will protect the buttons and screen on the top of the device body and prevent the operator from accidentally touching the control buttons.

[0037] like Figure 5 and Figure 6 As shown, a fixed box is fixedly installed at the rear end of the equipment body, springs 2 are fixedly installed at the left and right ends inside the fixed box, a moving plate is fixedly installed on the side opposite to the spring 2, rack 2 is fixedly installed on the right side of the left moving plate, rack 1 is fixedly installed on the left end of the right moving plate, gears are rotatably connected to the front end of the fixed box, and the gears are meshed with racks 1 and 2, clamping blocks are fixedly installed on the top of the moving plate, a mounting plate is fixedly installed on the left end of the moving block, a belt 1 is fixedly installed on the rear end of the mounting plate, and the other end of the belt 1 is fixedly connected to one side of the left clamping block.

[0038] The above scheme is adopted: when the moving block moves, the mounting plate will move along, and then the mounting plate will pull the belt 1 to move, and then the belt 1 will pull the clamping block at the left end to move left, and then the clamping block at the left end will drive the moving plate at the left end to move left, and then the moving plate will squeeze the spring 2 at the left end, and then the moving plate at the left end will pull the rack 2 to move, because the rack 1 and the rack 2 are meshed with the gear, and then when the rack 2 moves, it will drive the gear to rotate, and then the gear will drive the rack 1 to move right, and then the moving plate at the right end will squeeze the spring 2 at the right end, and then the two moving plates will drive the clamping blocks to move toward each other, and then the plug can be inserted into the rear end of the device body;

[0039] After the plug is inserted into the rear end of the device body and the protective shell 2 is rotated to make the button on the top of the device body appear, the hinge rod can be loosened, and then the moving block will be reset, and then the compressed spring 2 will push the moving plate to move relative to it, and then the moving plate will drive the clamping block to move, and then the surface of the clamping block will contact the surface of the plug, and then the plug can be fixed to prevent the plug from detaching from the rear end of the device body during treatment, which will affect the treatment effect.

[0040] like Figure 7 and Figure 8 As shown, a mounting groove is fixedly installed at the bottom end of the protective shell one, a mobile power supply is plugged into the interior of the mounting groove, an insertion block is arranged inside the mounting groove, the insertion block and the mounting groove are elastically connected by a spring three, an extrusion block is arranged inside the insertion block, the extrusion block and the mounting groove are elastically connected by a spring four, a guide plate is fixedly installed on one side of the mounting groove, a belt two located inside the guide plate is fixedly installed on one end of the extrusion block, and one end of the belt two is fixedly connected to the hinge rod.

[0041] By rotating the hinged rod to cancel the limit on the protective shell 2, the hinged rod will pull the belt 2 to slide inside the guide plate, and the guide plate can guide and limit the belt 2, and then the moving belt 2 will pull the extrusion block to move, and when the extrusion block moves, the spring 4 will be stretched, and then one side of the extrusion block will contact one side inside the plug block. Since the opposite sides of the extrusion block and the plug block are both inclined, when the extrusion block moves, it will squeeze and push the plug block, and when the plug block moves, the spring 3 will be compressed, and then the plug block will shrink to the inside of the installation slot, and then the mobile power supply can be inserted Inside the installation slot, after the insertion is completed, the hinge rod can be loosened, and the stretched spring four will pull the extrusion block away from the plug block, and then the compressed spring three will push the plug block to reset, and the plug block will contact one side of the mobile power supply, thereby fixing the mobile power supply. After the fixation is completed, the plug on one side of the mobile power supply can be inserted into the charging port on one side of the device body, and then the device can be charged. Finally, the hinge rod is rotated to shrink the belt two into the installation slot, and then the mobile power supply can be fixed, thereby improving the stability of device charging and extending the use time of the device.

[0042] like Figure 2 As shown, a stopper is fixedly installed on the surface of the fixed rod, and the opposite side of the stopper contacts the two ends of the rotating rod. The protective shell 1 is made of rubber material, and the sizes of the device body and the protective shell 1 are matched.

[0043] The above scheme is adopted: through the design of the fixed rod and the rotating rod, when the rotating rod rotates, the opposite side of the stopper contacts the two ends of the rotating rod, thereby limiting the rotating rod and the protective shell 2 to avoid displacement of the positions of the rotating rod and the protective shell 2; through the design of the device body and the protective shell 1, the protective shell can be put on the surface of the device body, and since the protective shell 1 is made of rubber material, the surface of the device body can be protected.

[0044] like Figure 5 As shown, magnet one is fixedly installed on the bottom end of protective shell two, magnet two is fixedly installed on the top end of the equipment body, support grooves are opened on the front and back sides inside the fixed box, and a support plate is slidably connected inside the support groove, and the opposite side of the support plate is fixedly connected to the two ends of rack two and rack one.

[0045] The above scheme is adopted: through the design of magnet one and magnet two, when the bottom end of protective shell two contacts with the top end of the equipment body, the opposite sides of magnet one and magnet two will contact, and then through the principle of opposites attract, the fixing effect of protective shell two is increased; through the design of support groove and support plate, when rack one and rack two move, the support plate will move inside the support groove, and because the surface of the support plate contacts with the inner wall of the support groove, rack one and rack two can be supported and limited.

[0046] like Figure 5 and Figure 6 As shown, there are four springs 2, and each group of two springs 2 is located at the left and right ends of the fixed box. A telescopic rod is arranged inside the spring 2, and the opposite side of the clamping block is designed in an arc shape, and the clamping block is designed to be longitudinally symmetrical about the center of the fixed box.

[0047] The above scheme is adopted: through the design of spring 2, when the two movable plates move relative to each other, the movable plate will squeeze spring 2. Since a telescopic rod is arranged inside spring 2, spring 2 can be limited to avoid position shift when spring 2 is compressed, which causes the position of the movable plate to shift. Through the design of the clamping block, since the opposite side of the clamping block is designed in an arc shape and then matches the surface of the plug, the clamping block can tightly fix the plug.

[0048] like Figure 1 and Figure 2As shown, a fixing groove is opened at the left end of the fixing shell, and the protrusion can move inside the fixing groove. The protrusion is cylindrical in design. There are two earphone bodies, and the opposite side of the earphone body is made of silicone material.

[0049] The above scheme is adopted: through the design of the protrusion, when the protrusion moves, it will move inside the fixed groove, so that the protrusion can be limited, and the protrusion is designed to be cylindrical, so that the protrusion can move smoothly inside the connecting plate; through the design of the earphone body, when the earphone body is placed into the auricle, since one side of the earphone body is made of silicone material, the earphone body can fit the user's auricle tightly, and the silicone material is relatively soft, so the user's auricle can be protected.

[0050] The working principle and use process of the present invention:

[0051] First, the operator can rotate the hinged rod, and then the hinged rod will drive the connecting plate to rotate, then the protrusion will move inside the connecting plate and move forward, then the protrusion will squeeze the spring 1, then the protrusion will pull the moving block and the plug rod forward, then the plug rod will move away from the inside of the connecting block, and then the protective shell 2 can be rotated to make the button on the top of the device body appear.

[0052] When the protrusion moves forward, it will pull the mounting plate and belt 1 to move, and then belt 1 will pull the clamping block at the left end to move left, and then the clamping block at the left end will drive the left moving plate to move, and then the left moving plate will squeeze the left spring 2, and the moving plate will drive the rack 2 to move, and then the rack 2 will drive the gear to rotate, and the gear will drive the rack 1 to move right, and then the rack 1 will push the moving plate at the right end to move, and then the moving plate will squeeze the right spring 2, and then the plug can be inserted into the rear end of the device body, and then the hinge rod is released, and then the compressed spring 1 will push the moving block and the plug rod to reset, and then the compressed spring 2 will push the moving plate to move relative to each other, and then the surface of the moving plate will contact the surface of the plug, and then the plug can be fixed, and then the earphone body is placed inside the user's auricle, and then the button on the top of the device body can be pressed, and then a microcurrent will be generated inside the device body, and then the microcurrent will pass through the connecting line and the earphone body, and then the microcurrent will stimulate the user's brain, and then microcurrent stimulation treatment will be performed;

[0053] And when the hinge rod rotates, the hinge rod will pull the belt 2 to slide inside the guide plate, the belt 2 will pull the extrusion block to move, the extrusion block will squeeze and push the plug block, and when the plug block moves, the spring 3 will be compressed, and then the plug block will shrink into the inside of the installation slot, and then the mobile power supply can be inserted into the inside of the installation slot, after the insertion is completed, the hinge rod can be released, and the stretched spring 4 will pull the extrusion block away from the plug block, and then the compressed spring 3 will push the plug block to reset, and the plug block will contact one side of the mobile power supply, so as to fix the mobile power supply, and after the fixation is completed, the plug on one side of the mobile power supply can be inserted into the charging port on one side of the device body, so as to charge the device;

[0054] After the treatment is completed, the hinged rod is rotated again, and the belt 1 will drive the clamping block to move relative to each other, and then the clamping block will move away from the surface of the plug, thereby canceling the fixation of the plug, and then the plug can be pulled out from the rear end of the device body, and then the hinged rod will drive the connecting plate to move, and then the moving block and the plug rod will move forward again, and then the protective shell 2 is rotated in the opposite direction. When the bottom end of the protective shell 2 contacts the top end of the protective shell 1, the connecting block and the plug rod will be aligned, and then the hinged rod is released, and then the compressed spring 1 will push the moving block and the plug rod to enter the interior of the connecting block again, so that the protective shell 2 can be fixed, and then the protective shell 2 can protect the buttons and the screen, and prevent the operator from accidentally touching the control button, and finally complete the operation process.
