[0060] Laser hair removal method, the steps of laser hair removal method include:

[0061] Step 1: Preparation for hair removal;

[0062] Step 2: Hair removal operation stage;

[0063] Step 3: Post-stripping care stage;

[0064] Step 1 includes cleaning the hair removal area and applying gel: Use a disposable hair removal knife to shave all the hair on the hair removal area and keep the hair removal area clean, then apply a cooling and refreshing gel to the hair removal area to protect the skin and reduce discomfort during the hair removal process;

[0065] Step 2 includes adjusting the energy and handheld device: according to the hair removal area and the skin condition of the hair removal area, adjust the appropriate laser energy, hold the hair removal instrument, and move it back and forth repeatedly on the hair removal area with uniform force to make the hair follicles fully absorb the laser energy.

[0066] Step three includes the post-hair removal care part: turn off the hair removal device, gently scrape off the cold gel on the skin, and apply ice cubes wrapped in gauze to the hair removal area to relieve the redness, heat, swelling and pain of the skin after hair removal.

[0067] The complete usage steps and working principle of the above embodiment are as follows:

[0068] The following is the working process of controlling the driving mechanism 5 to push the laser head 4 when placing:

[0069] In the initial state, if Figure 1 and Figure 3 As shown, the cone head cover 3 is fixedly arranged at the bottom of the hair removal device body 1, and the placement base 501 is arranged on the outer side of the cone head cover 3 and the lower end of the hair removal device body 1, that is, the user can insert the device into the placement base 501 for placement when not in use or at the end of use, and because the bottom wall of the placement base 501 is fixedly provided with a counterweight block 504, it can be referred to Figure 2 As shown, gravity can be applied to the placement base 501, so that the placement base 501 can be more stable when placing the instrument, thereby preventing the instrument from tipping over and falling during placement, thereby preventing the instrument from being damaged;

[0070] When the user is using it, the device can be taken out from the base 501, and the power button 2 can be long pressed to start the device to start the operation and perform the hair removal step on the skin. After the hair removal is completed, the user can reinsert the device into the base 501 and press the hair removal device body 1 downward. Figure 2 and Figure 6As shown, since the first elastic telescopic column 502 is symmetrically fixedly arranged on the inner bottom wall of the placement base 501, and the top plate 503 is fixedly arranged on the top of the first elastic telescopic column 502 (it should be noted here that when the instrument is initially inserted, the upper surface of the top plate 503 always maintains contact with the lower surface of the cone head cover 3, and the top plate 503 can synchronously lift the cone head cover 3 and the hair removal device body 1 upward under the elastic force of the first elastic telescopic column 502), when the user presses the hair removal device body 1 downward, the pushing action of the cone head cover 3 can drive the top plate 503 to move downward and synchronously squeeze the first elastic telescopic column 502. At the same time, because the sponge abutment plate 505 is fixedly arranged on the upper surface of the counterweight block 504, when the instrument moves downward, the laser head 4 inside the cone head cover 3 moves downward synchronously. Moreover, because the upper surface of the laser head 4 is fixedly provided with a fixing plate 507, and both sides of the fixing plate 507 The sliders 508 are symmetrically fixedly arranged, and the groove walls on both sides of the cone head cover 3 are symmetrically provided with slide grooves 506 that are slidably adapted to the sliders 508, and a first return spring 509 is fixedly arranged between the top wall of the slide groove 506 and the slider 508, so that the laser head 4 can be movably arranged in the cone head cover 3, and as the cone head cover 3 moves, the laser head 4 will contact the surface of the sponge support plate 505, and through the continued downward movement of the cone head cover 3, the laser head 4 can be driven to move upward inside the cone head cover 3 under the blocking action of the sponge support plate 505 (in this process, the sponge support plate 505 is used to flexibly lift the laser head 4 during the process of squeezing the cone head cover 3 downward, thereby avoiding wear on the surface of the laser head 4 and protecting the laser head 4). At this time, the slider 508 synchronously slides upward inside the slide groove 506 and squeezes the first return spring 509. Figure 6 and Figure 8 As shown, because the opposite side of the slider 508 is provided with a slot 510, and the inner bottom wall of the slot 510 is fixedly connected to the second elastic telescopic column 511, and the end of the second elastic telescopic column 511 away from the inner bottom wall of the slot 510 is fixedly provided with a limit block 512, according to Figure 8 As shown, the stop block 512 is set in a hemispherical shape, and a profiling groove 513 is opened at the lower end of the groove wall on the opposite side of the slide groove 506, and a rubber sensing pad 514 is fixedly set at the upper end of the groove wall on the opposite side of the slide groove 506, and the opposite side of the rubber sensing pad 514 and the profiling groove 513 are adapted to the shape of the stop block 512, which can cooperate with Figure 7As shown, initially when the laser head 4 is not pushed, the limit block 512 will be stuck in the inner part of the profiling groove 513, so that the lower surface of the laser head 4 can be flush with the lower surface of the cone head cover 3, so that the laser head 4 can contact the skin. When the laser head 4 is pushed to move upward, the limit block 512 will move out of the profiling groove 513 and be blocked by the groove wall of the slide groove 506, so that the limit block 512 will retract to the inner part of the embedded groove 510. At this time, the second elastic telescopic column 511 is squeezed synchronously, and as the laser head 4 moves upward, the limit block 512 will move out of the profiling groove 513 and be blocked by the groove wall of the slide groove 506, so that the limit block 512 will retract to the inner part of the embedded groove 510. At this time, the second elastic telescopic column 511 is squeezed synchronously, and as the laser head 4 moves upward. When the laser head 4 approaches the rubber sensing pad 514, due to the wide space, the limit block 512 can be pushed outward from the inside of the embedding groove 510 under the elastic force of the second elastic telescopic column 511, and finally the limit block 512 can be snapped onto the rubber sensing pad 514, thereby limiting the moving position of the laser head 4, so that the laser head 4 and the lower surface of the cone head cover 3 can be staggered with each other (that is, not in the same horizontal plane), and at this time, the sponge plate 505 still maintains a close contact with the lower surface of the laser head 4;

[0071] After the user presses the instrument downward so that the limit block 512 moves out of the contoured groove 513 and finally engages with the rubber sensing pad 514, the pressure on the instrument can be released. At this time, the downward thrust exerted by the cone head cover 3 on the top plate 503 disappears. Under the elastic force of the first elastic telescopic column 502, the top plate 503 can be driven to move upward, and the cone head cover 3 can be lifted upward to release the contact between the lower surface of the laser head 4 and the sponge support plate 505, so that there is space between the laser head 4 and the lower surface of the cone head cover 3, so as to facilitate the subsequent use of the dynamic cleaning mechanism 6 and avoid interference with the use of the dynamic cleaning mechanism 6.

[0072] The rubber sensing pad 514 is composed of a rubber pad and a contact sensing sheet, and the contact sensing sheet is electrically connected to the micro motor 603 in the dynamic cleaning mechanism 6 described later. A groove body adapted to the limit block 512 is synchronously opened on the opposite side of the rubber pad, and the contact sensing sheet is fixedly connected to the inner surface of the groove body, that is, when the limit block 512 moves from the inside of the lower profiling groove 513 to the rubber sensing pad 514, the contact sensing sheet senses it, and the micro motor 603 can be synchronously started and operated through the electrical connection relationship to clean the lower surface of the laser head 4. The specific cleaning steps are shown later, and will not be elaborated on here.

[0073] In the above process, by controlling the coordinated setting of the driving mechanism 5 and the dynamic cleaning mechanism 6, the operation of the cleaning structure can be automatically triggered to automatically clean the lower surface of the laser head 4 when the user has used the hair removal instrument and placed it for storage, without the need for the user to manually maintain the surface of the laser head 4, thereby saving the user's time and energy and improving the efficiency and convenience of cleaning. In addition, the automatic cleaning method can ensure that the laser head 4 can be cleaned in time after each use, avoiding the accumulation of dirt and residues, helping to maintain the surface cleanliness of the laser head 4, extending its service life, and reducing the performance degradation caused by dirt. Compared with the manual cleaning method of the user, the automatic cleaning method can effectively reduce the frequency of manual cleaning by the user and reduce the risk of damage to the laser head 4 caused by improper or untimely cleaning, thereby reducing maintenance costs and repair frequency.

[0074] Please refer to the above working process Figures 1 to 8 .

[0075] The following is the working process of the dynamic cleaning mechanism 6 cleaning the lower surface of the laser head 4 after the laser head 4 moves upward:

[0076] In the above text, the limit block 512 moves from the inside of the contoured groove 513 to the rubber sensing pad 514, and senses through the contact sensing sheet, while starting the micro motor 603 in the dynamic cleaning mechanism 6 to run. Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, since a rectangular groove 601 is provided at the lower end of the cone head cover 3, a processing chamber 602 is provided inside the two ends of the cone head cover 3, and a micro motor 603 is fixedly arranged at the rear end of the processing chamber 602, a bidirectional reciprocating screw rod 604 is rotatably arranged between the inner walls on both sides of the rear end of the rectangular groove 601, and one end of the bidirectional reciprocating screw rod 604 is fixedly connected to the output end of the micro motor 603. When the micro motor 603 is running, it can synchronously drive the bidirectional reciprocating screw rod 604 connected to its output end to rotate between the inner walls on both sides of the rear end of the rectangular groove 601. In addition, since a sliding screw rod 604 is fixedly arranged between the inner walls on both sides of the front end of the rectangular groove 601, Rod 605, and a linkage frame 606 is symmetrically arranged between the slide bar 605 and the two-way reciprocating screw rod 604, and a mounting plate 609 is clamped on the linkage frame 606, and a cleaning cotton 610 is fixedly arranged on the top of the mounting plate 609, so that the cleaning cotton 610 can be installed on the linkage frame 606 under the connection of the mounting plate 609, and one end of the linkage frame 606 is threadedly connected to the two-way reciprocating screw rod 604, and the other end is slidably connected to the slide bar 605, so when the two-way reciprocating screw rod 604 rotates, the two linkage frames 606 can be synchronously driven to move toward each other to clean the lower surface of the laser head 4;

[0077] like Figure 4 and Figure 5 As shown, a placement slot 607 is provided at the front end of the linkage frame 606, and a liquid storage box 612 is placed in the placement slot 607. Infusion holes 611 are evenly provided on the mounting plate 609, and the infusion holes 611 are interconnected. The cleaning cotton 610 is arranged above the infusion hole 611. A through hole 608 is provided at one end of the linkage frame 606 close to the placement slot 607. When the mounting plate 609 is installed on the linkage frame 606, the through hole 608 and the infusion hole 611 are synchronously connected. A liquid guide tube 613 is fixedly connected on the liquid storage box 612, and the liquid guide tube 613 is clamped in the through hole 608. Through the connection limitation of the through hole 608, the liquid guide tube 613 and the infusion hole 611 can be synchronously connected, so that the disinfectant stored in the liquid storage box 612 can be introduced into the cleaning cotton 610 through the infusion hole 611 later.

[0078] Among them, a one-way valve is arranged between the liquid guide tube 613 and the liquid storage box 612, and the one-way valve is electrically connected to the switch key 2. When the switch key 2 is turned on, the one-way valve is opened synchronously, and the disinfecting liquid in the liquid storage box 612 is diffused and conducted to the cleaning cotton 610 through the infusion hole 611, and the cleaning cotton 610 is soaked by the user's use time. When the switch key 2 is closed, the one-way valve is closed synchronously, and the liquid delivery to the cleaning cotton 610 is stopped, so as to facilitate the cleaning cotton 610 to clean the lower surface of the laser head 4 later;

[0079] In the above process, by setting the dynamic cleaning mechanism 6 and utilizing the infusion hole 611 opened on the mounting plate 609, the disinfectant liquid in the liquid storage box 612 can be diffused and transported to the cleaning cotton 610 while the hair removal device is turned on for use, so that during the subsequent use of the hair removal device, the disinfectant liquid can be stably supplied to the cleaning cotton 610, so that the laser head 4 can always be in contact with fresh and effective disinfectant liquid when it is subsequently cleaned by the cleaning cotton 610, so that the cleaning cotton 610 can more effectively remove dirt and residues on the lower surface of the laser head 4, thereby improving the cleaning efficiency, ensuring the stable performance of the laser head 4 during the subsequent use, and thus improving the hair removal effect and user experience;

[0080] Please refer to the above working process Figures 1 to 8 .

[0081] The following is the working process of the reset auxiliary mechanism 7 to restore the position of the laser head 4 after the laser head 4 is cleaned:

[0082] like Figure 6 and Figure 7As shown, after the linkage frames 606 move toward each other to clean the lower surface of the laser head 4, the two linkage frames 606 can be driven to move in opposite directions through the thread limitation of the bidirectional reciprocating screw rod 604 to clean the lower surface of the laser head 4 again. At the same time, when the linkage frames 606 return to the initial position, since the inner top wall and the inner bottom wall at both ends of the rectangular groove 601 are symmetrically provided with connecting grooves 702, a push plate 701 is slidably arranged between the connecting grooves 702 on the same side, and a second reset spring 703 is fixedly arranged between the push plate 701 and the connecting groove 702, the linkage frame 606 will first contact the surface of the push plate 701 when moving. The push plate 701 is in contact with the linkage frame 606, and the linkage frame 606 continues to move in the direction of the push plate 701 under the continuous driving of the thread, so that the push plate 701 slides synchronously on the connecting groove 702 and squeezes the second return spring 703. At this time, since the linkage rod 704 is fixedly connected to the opposite side of the push plate 701, the fixing blocks 705 are symmetrically fixedly arranged on the top wall and the bottom wall of the processing chamber 602, and the linkage rod 704 and the lower end fixing block 705 are connected through sliding. Therefore, when the push plate 701 is pushed, the linkage rod 704 can be synchronously driven to slide outward through the fixing block 705, and the upper end fixing block 705 is provided with a driven rod for sliding through. 707, and a telescopic plate 706 is symmetrically rotated between the driven rod 707 and the right end of the linkage rod 704. When the linkage rod 704 is pushed to move outward, the connection effect of the telescopic plate 706 can drive the driven rods 707 inside the processing chambers 602 at both ends of the cone head cover 3 to move toward each other, that is, to move in the direction of the rubber sensing pad 514. Because a push block 708 is fixedly provided at one end of the driven rod 707 facing the rubber sensing pad 514, when the driven rod 707 moves, the push block 708 moves synchronously and pushes the rubber sensing pad 514, so that the limit block clamped on the rubber sensing pad 514 512 can be pushed synchronously and squeeze the second elastic telescopic column 511, so that the limit block 512 retracts to the inside of the embedding groove 510. At this time, the limit block 512 releases the restriction on the fixing plate 507. The fixing plate 507 is driven to move downward inside the cone head cover 3 under the elastic force of the first return spring 509, so that the limit block 512 is re-engaged in the inside of the profiling groove 513 to restore the position of the laser head 4. The position of the laser head 4 can be limited by the clamping connection relationship between the limit block 512 and the profiling groove 513, thereby enhancing the stability of the laser head 4 in the subsequent use process.

[0083] As the two-way reciprocating screw rod 604 continues to rotate, the linkage frame 606 can be driven to push the push plate 701, so that the two linkage frames 606 move in the opposite direction to the initial position, thereby canceling the push on the push plate 701, so that the push plate 701 can be pushed back to the initial position under the elastic force of the second reset spring 703. At this time, through the linkage between the structures, the push block 708 can move in the opposite direction and return to the initial position, so as to facilitate the next use, thereby completing the cleaning and reset of the lower surface of the laser head 4;

[0084] In the above process, by setting the reset auxiliary mechanism 7, using the linkage frame 606 to push the push plate 701, and cooperating with the design of the linkage rod 704, the telescopic plate 706 and the driven rod 707, the push block 708 can be moved and the limit block 512 can be pushed out from the inside of the rubber sensing pad 514 while the cleaning cotton 610 cleans and resets the lower surface of the laser head 4, so that the laser head 4 that has moved upward can move downward and return to its original position, and keep it flush with the lower surface of the cone head cover 3, thereby ensuring that the laser head 4 can be quickly and stably reset to the initial position, thereby realizing the automatic reset of the laser head 4 after cleaning is completed, simplifying the operation process, and making the entire process more integrated and automated;
