[0038] refer to Figure 1-Figure 13 This embodiment provides a beauty instrument, including: a beauty instrument body 1 and a first action head 2.
[0039] The first action head 2 includes a shell 21, an ultrasonic transducer assembly 22, an upper cover 211, a lower cover 23 and a reciprocating mechanism 24; the reciprocating mechanism 24 is used to drive the ultrasonic transducer assembly 22 to reciprocate in the horizontal direction to increase the action range of the ultrasonic transducer assembly 22.
[0040] Therefore, the ultrasonic transducer assembly 22 is fixed on the slider; the housing 21 and the lower cover 23 define an area for accommodating the reciprocating motion mechanism 24 and the ultrasonic transducer assembly 22 .
[0041] In order to drive the ultrasonic transducer assembly 22 to reciprocate in the horizontal direction, the reciprocating mechanism 24 in this embodiment includes: a driving member 241 , a slider 242 , and a crank 243 ; the driving member 241 is a reduction stepping motor. The slider 242 is provided with a slide slot 244 .
[0042] The crank 243 is connected to the output shaft, and one end of the crank 243 is slidably connected to the slide slot 244; the rotation of the driving member 241 drives the crank 243 to rotate.
[0043] In this embodiment, the upper cover 211 and the waterproof gland 215 cooperate to form an inner cavity, and the upper cover 211 has a boss 214 extending radially inward, and the boss 214 and the waterproof gland 215 form a slide rail 219, and the slider 242 reciprocates in the slide rail 219. When the crank 243 rotates, the slider 242 is driven to reciprocate along the slide rail 219, and the slider 242 slides and abuts against the end of the waterproof gland 215. During the sliding process, in order to make the slider 242 slide more smoothly, the crank 243 can move in the slide groove 244 of the slider 242 to adjust the appropriate position.
[0044] The slider 242 is disposed in the inner cavity; an opening 212 is disposed in the upper surface of the housing 21 in the region corresponding to the inner cavity. Thus, the focused ultrasonic wave output by the ultrasonic transducer assembly 22 can be emitted through the opening 212. In order to prevent water from leaking, a waterproof film 213 is attached to the opening 212.
[0045] And because the inner cavity needs to be filled with water as a medium to transmit ultrasonic waves, in order to avoid water leakage, the upper cover 211 is fixedly connected to the waterproof pressure cover 215 to seal the inner cavity; the waterproof pressure cover 215 is provided with a clearance opening 2151 for the output shaft to pass through, and the part of the output shaft located in the clearance opening 2151 is in contact with the inner wall of the clearance opening 2151 through a sealing ring 2152. In this way, even if the waterproof pressure cover 215 is provided with a clearance opening 2151, the inner cavity can still be reliably sealed.
[0046] Since the housing 21 is provided with an outer cavity in addition to an inner cavity, other functions can be provided to the action head by providing other devices in the outer cavity. For example, in this embodiment, radio frequency electrode heads are provided at intervals along the circumference at the position of the outer cavity corresponding to the upper surface of the housing 21. In this way, the first action head 2 has two beauty functions: ultrasound and radio frequency.
[0047] In order to install the ultrasonic transducer assembly in this embodiment, the ultrasonic transducer assembly 22 includes an ultrasonic transducer 221 and a pressure cover 222 ; the pressure cover 222 is locked to the upper surface of the slider 242 , and the ultrasonic transducer 221 is installed in the pressure cover 222 .
[0048] Furthermore, in order to control the deceleration stepper motor and the RF electrode head, a second control circuit board 217 is provided in the outer cavity for outputting electrical signals to the RF electrode head. A first control circuit board 216 is provided in the area of the lower cover 23 corresponding to the outer cavity, and the first control circuit board 216 is used to output electrical signals to the driving member 241.
[0049] Furthermore, in this embodiment, the first control circuit board 216 is provided with Hall sensors 218 on both sides of the inner cavity along the length direction, and the driving member 241 is also provided with magnets on both sides along the length direction. In this way, the current position of the ultrasonic transducer 221 can be detected by the cooperation of the magnet and the Hall sensor 218.
[0050] In this embodiment, in order to further increase the functions of the beauty instrument, the beauty instrument body 1 and the first action head 2 can be set to a detachable connection relationship. In this way, the user can easily remove the first action head 2 from the beauty instrument body 1, and then replace the other second action head 4 to achieve different beauty functions. In this embodiment, the beauty function that the second action head 4 can achieve is light therapy + fractional radio frequency.
[0051] In order to facilitate the replacement of the action head, the beauty instrument body 1 is provided with an action head switching operation component, and the operation component drives the connection structure 14 provided on the beauty instrument body 1 to move from the locked position to the unlocked position under the action of an external force. Specifically, the action head switching operation component includes a button 11, a reset member 12 and a reversing member; the reversing member is connected between the button 11 and the connection structure 14, and is used to reverse the movement of the button 11 under the action of an external force into a translational movement of the connection structure 14 between the locked position and the unlocked position; one end of the reset member 12 abuts against the connection structure 14, and when the connection structure 14 moves from the locked structure to the unlocked position, the reset member 12 is compressed to accumulate elastic reset force.
[0052] In this embodiment, the switching member is a first inclined surface 13 connected to the button 11, and a second inclined surface 15 provided on the connecting structure 14; when the button 11 is pressed, the first inclined surface 13 and the second inclined surface 15 move relative to each other, and the generated force can drive the connecting structure 14 to move. The connecting structure 14 in this embodiment is a buckle, and when the connecting structure 14 is in the locking position, the buckle cooperates with the slot of the action head to lock. When the connecting structure 14 is in the unlocking position, the buckle is separated from the slot of the action head, so that the action head can be removed.
[0053] Finally, the present embodiment further includes a base 3; the base 3 is provided with a charging compartment 31 and a disinfection compartment 32; the base 3 is provided with a button for controlling the start or shut down of the disinfection compartment 32. In addition to charging the beauty instrument body 1 with the base 3, the user can also use the disinfection compartment 32 to disinfect and sterilize each action head.
[0054] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
