Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical beauty equipment, in particular to an ultrasonic medical beauty equipment. Background Art
[0002] The existing focused ultrasound medical beauty treatment instrument mainly uses ultrasound to focus on tissues such as the epidermis, dermis, and fascia of the human skin, generating minor injuries, stimulating the tissue self-repair mechanism, and inducing the regeneration of deep collagen, so as to achieve the effect of tightening and lifting the skin. The focusing depth of the treatment head used in the existing focused ultrasound medical beauty treatment instrument is fixed, that is, the focusing depth of each treatment head at each depth is fixed and cannot be adjusted. However, due to certain differences in the fatness, thinness, skin thickness, etc. of each person, the thickness and depth of tissues such as the epidermis, dermis, and fascia of each person are different. Therefore, the current focusing depths of the existing treatment heads for different tissues cannot well adapt to the differences in tissues among different people; in addition, even for the same person, the thickness and depth of tissues such as the epidermis, dermis, and fascia will also be different at different ages and different physical state stages (such as fatness and thinness). This will result in relatively large differences in the beauty effects of the fixed ultrasonic medical beauty treatment equipment for each person.

[0034] The following will be combined with Figures 1 - 7 to describe the ultrasonic medical aesthetic device provided by the present utility model.
[0035] In view of the problem in the traditional technology that it is difficult for ultrasonic medical aesthetic devices to adapt to the physical conditions of different patients, resulting in inaccurate ultrasonic focusing effects, the embodiments of the present utility model provide an ultrasonic medical aesthetic device, including a device body 1, an ultrasonic working head 2, and a connection structure 3.
[0036] The main body of the device 1 is provided with a mounting hole 11, and the back surface of the ultrasonic working head 2 is provided with a mounting post 21, and the mounting post 21 passes through the mounting hole 11. The connecting structure 3 includes a driving member and a transmission frame 32. The transmission frame 32 is arranged inside the main body of the device 1. The driving member drives and connects the transmission frame 32 so that the transmission frame 32 has a moving stroke along the axial direction of the main body of the device 1. The transmission frame 32 is used to clamp and fix the mounting post 21 when approaching the mounting post 21 and release the mounting post 21 when moving away from the mounting post 21. In this way, the ultrasonic working head 2 has the effect of being detachably connected to the main body of the device 1. Compared with the traditional integrated ultrasonic aesthetic medical device, for the ultrasonic aesthetic medical device provided by the present utility model, the ultrasonic working head 2 and the main body of the device 1 are detachably connected, and different models of ultrasonic working heads 2 can be selected according to the actual treatment needs of users, which not only improves the safety of the ultrasonic aesthetic medical device but also enhances the treatment effect of focused ultrasound aesthetics. Further, the present utility model fixes the ultrasonic working head 2 by means of plugging and fixing the mounting post 21, and the disassembly and installation are both simpler and quicker.
[0037] There are various ways to fix the mounting post 21. In an alternative embodiment, an elastic clip can be provided on the transmission frame 32. When the elastic clip approaches the mounting post 21, the mounting post 21 can be squeezed into the inside of the elastic clip, so that the elastic clip can clamp the mounting post 21 to complete the fixation of the ultrasonic working head 2. When the elastic clip moves away from the mounting post 21, the mounting post 21 can be disengaged from the elastic clip to complete the disassembly of the ultrasonic working head 2. In another alternative embodiment, a slot 22 is provided on the mounting post 21, and a clamping block 326 is provided on the transmission frame 32. The transmission frame 32 is used to make the clamping block 326 snap into the slot 22 when approaching the mounting post 21 to clamp and fix the ultrasonic working head 2, and the clamping block 326 disengages from the slot 22 when moving away from the mounting post 21 to release and disassemble the ultrasonic working head 2.
[0038] As described above, the transmission frame 32 has a moving stroke along the axial direction of the main body of the device 1. In the technical solution provided by the present utility model, the transmission frame 32 includes a frame body 321 and a transmission arm 322 provided at the end of the frame body 321. Reference can be made to Figure 7 , a wedge block 323 is provided on one side of the transmission arm 322, and the wedge block 323 has a wedge surface. The driving member includes a button 31 that movably passes through the main body of the device 1. When the user clicks the button 31, the end of the button 31 abuts against and pushes the wedge surface of the wedge block 323, so as to drive the transmission frame 32 to move along the axial direction of the main body of the device 1. It should be noted that reference can be made to Figures 1 - 7When the user presses the button 31, the transmission frame 32 moves away from the mounting post 21. At this time, the latch 326 on the transmission frame 32 disengages from the card slot 22, and the user can disassemble or install the ultrasonic working head 2. When the user releases the button 31, the transmission frame 32 moves towards the mounting post 21. At this time, the latch 326 of the transmission frame 32 is inserted into the card slot 22 again, and the ultrasonic working head 2 is fixed to the device body 1. The control method using the button 31 does not require a complex driving structure, is simpler and faster, and has higher safety.
[0039] To improve the stability of the button 31 drive, in the technical solution provided by the present invention, a limit block 324 is further provided on one side of the wedge block 323. A limit groove 325 is formed between the limit block 324 and the wedge block 323, and the wedge surface of the wedge block 323 faces the limit block 324. The end of the button 31 moves within the limit groove 325, which not only prevents the button 31 from being misaligned but also improves the driving accuracy. Specifically, please refer to Figure 7 , the button 31 includes a mounting shaft 312, an end cap 311, and a spring 34. An installation port 12 is provided on the device body 1. The end cap 311 is provided at the end of the mounting shaft 312 and is located in the installation port 12, and the spring 34 is sleeved on the mounting shaft 312. The mounting shaft 312 and the spring 34 move within the limit groove 325. When the user presses the button 31, the wall surface of the mounting shaft 312 will push the wedge block 323, causing the transmission frame 32 to move. When the user stops pressing the button 31, the button 31 will automatically return to its original position under the elastic force of the spring 34. It should be noted that in order to improve functionality, a lamp ring and a light-transmitting band are also provided on the button 31 to provide a reminder to the user.
[0040] In order to optimize the layout of internal components of the device and reduce the volume of the device, in the technical solution provided by the present utility model, the device body 1 includes a holding part 13 and a connecting part 14. The inner cavities of the holding part 13 and the connecting part 14 are communicated. The ultrasonic working head 2 is arranged on the end face of the connecting part 14. The frame body 321 is arranged inside the connecting part 14. The end of the transmission arm 322 is located inside the connecting part 14, and the rest is arranged inside the holding part 13. Specifically, the transmission arm 322 includes a first section 3221 and a second section 3222 that are perpendicular to each other. The first section 3221 is arranged at the end of the frame body 321. The first section 3221 is located inside the connecting part 14 and is inclined to the frame body 321. The second section 3222 is located inside the holding part 13 and extends along the axial direction of the holding part 13. In an alternative embodiment, the first section 3221 is perpendicular to the frame body 321, and the second section 3222 is parallel to the frame body 321. It should be noted that through the arrangement of the transmission arm 322, a certain height difference is generated between the holding part 13 and the connecting part 14, which can optimize the structural layout, so that the button 31 can drive the transmission frame 32 that is not in the same plane to move, and further make the holding part 13 and the connecting part 14 smaller in size. On the one hand, it is convenient to hold, and on the other hand, it can also enhance the overall aesthetic feeling of the device.
[0041] Further, the connecting structure 3 further includes a reset member. The reset member includes a mounting block 33 and a spring 34. The mounting block 33 is arranged on the inner wall of the connecting part 14. One end of the spring 34 is connected to the mounting block 33, and the other end is connected to the clamping block 326. When the button 31 is pressed to drive the transmission frame 32 away from the mounting post 21, the spring 34 is compressed. When the user no longer presses the button 31, the spring 34 resets and drives the transmission frame 32 to approach the mounting post 21, and the clamping block 326 clamps and fixes the mounting post 21 to complete the fixing of the ultrasonic working head 2. Furthermore, in order to guide the movement of the transmission frame 32 and also to guide the deformation of the spring 34, a guide shaft 35 is arranged on the mounting block 33, and a guide post 327 is arranged on the clamping block 326. The two ends of the spring 34 are respectively sleeved on the guide shaft 35 and the guide post 327.
[0042] The ultrasonic working head 2 belongs to a high-precision instrument, so it is necessary to ensure its stable fixation to prevent it from falling and being damaged. Further, the ultrasonic working head 2 includes three mounting posts 21, and the mounting holes 11 are correspondingly set to three for the clamping blocks 326. For reference, see Figure 6, the three clamping blocks 326 are distributed in a triangle. Two clamping blocks 326 are respectively arranged on both sides of the frame body 321, and one clamping block 326 is arranged inside the frame body 321. In this way, the ultrasonic working head 2 is stably connected to the equipment body 1 through three-point fixation. Further, an avoidance hole 328 is formed in the frame body 321. The avoidance hole 328 is used for the mounting post 21 to pass through. After passing through the avoidance hole 328, the mounting post 21 is clamped with the clamping block 326 inside the frame body 321. It should be noted that the avoidance hole 328 is set to be strip-shaped. On the one hand, it avoids the mounting post 21, and on the other hand, it can also guide the movement of the transmission frame 32 through the sliding socket connection with the mounting post 21. Further, a plurality of guiding holes 329 are provided on the transmission arm 322, and a plurality of support columns 19 are provided on the inner wall of the equipment body 1. The support columns 19 are arranged in the guiding holes 329. On the one hand, they can support the transmission frame 32, and on the other hand, they can also guide the movement of the transmission frame 32.
[0043] Further, a slot 15 is formed in the equipment body 1. The slot 15 is located between the mounting holes 11. A power connection post 16 is arranged in the slot 15. A socket 23 is arranged on the back of the ultrasonic working head 2. A power connection hole 24 is arranged in the socket 23. The socket 23 is inserted into the slot 15 to electrically connect the ultrasonic working head 2 to the equipment body 1. It should be noted that the slot 15 and the socket 23 can electrically connect the ultrasonic working head 2 to the equipment body 1 on the one hand. On the other hand, the positioning insertion between the two can also play a role in positioning and connecting the ultrasonic working head 2 to the equipment body 1. In this way, through double positioning, it can prevent the ultrasonic working head 2 from detaching from the equipment body 1 after the mounting post 21 detaches from the clamping block 326, causing dropping and damage. It should also be noted that the column body at the end of the power connection post 16 is arranged to be movable and telescopic, so as to facilitate positioning and installation.
[0044] The ultrasonic beauty medical equipment provided by the utility model is applicable to ultrasonic beauty medical treatment. An ultrasonic generator, a transducer and an ultrasonic diaphragm are arranged in the ultrasonic working head 2. Further, a circuit board 18 and a battery 17 are also arranged in the equipment body 1. It can be referred to Figure 2 and Figure 3 , the equipment body 1 includes a front shell and a rear shell. The front shell is used for installing the transmission frame 32, the battery 17 and the button 31, and the rear shell is used for installing components such as the circuit board 18. In order to make the equipment more miniaturized and beautiful, the holding part 13 is set to be columnar, and the connecting part 14 is set to be frustum-shaped. Correspondingly, the ultrasonic working head 2 can be set to be frustum-shaped.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
