Description

Technical Field

[0001] The present invention relates to the technical field of beauty instruments, and in particular to a beauty instrument and a control method thereof. Background Art

[0002] Ultrasonic beauty instrument is a device that uses ultrasonic mechanical vibration waves for beauty treatment. Through the action of ultrasound, it can promote the metabolism of skin cells, accelerate the decomposition and excretion of pigmentation spots, thereby achieving the effect of whitening, lightening spots, firming and removing wrinkles. Therefore, ultrasonic beauty instrument has gradually become one of the must-have appliances for more and more families.

[0003] Existing home ultrasonic beauty devices usually consist of two parts: a main unit and a treatment head. The treatment head is connected to the main unit through a signal line, and the treatment head is in the shape of a rod, which is convenient for users to hold. When using an ultrasonic therapeutic device, since the surface of human skin is relatively dry, it is not conducive to the conduction of ultrasonic waves. Therefore, it is necessary to first apply a layer of gel on the skin surface of the area to be massaged, and then fit the end of the treatment head to the user's skin, and slowly move the treatment head so that the treatment head rubs back and forth in the massage area, so that the ultrasonic waves can be evenly transmitted to the skin in various parts of the massage area. However, each time an ultrasonic massager is used, gel and a gluing tool (such as a brush) need to be prepared. After completion, the gluing tool may also need to be cleaned, which makes the massage steps more cumbersome.

[0004] In addition, as the massage time increases, the gel may gradually dry up, and under the repeated kneading of the treatment head, the gel may gradually slide off the skin surface, or be pushed out of the massage area, causing the skin surface of the massage area to gradually dry up. At this time, it is necessary to stop the massage action and then re-apply the gel to the dry area before continuing the massage, which further brings inconvenience to the massage process. In view of this, we propose a beauty instrument and its control method to well solve the above disadvantages. Summary of the invention

When the treatment head is tilted toward a certain side, only the glue outlet holes close to the tilted side can discharge glue normally, and the other glue outlet holes cannot discharge glue because the solenoid valves are in a closed state. Therefore, the present invention can discharge glue in a directional manner during the massage process. On the one hand, it can improve the accuracy of glue discharge, and on the other hand, it also helps to avoid gel waste. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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.

[0036] Example 1: Please refer to Figure 1 - Fig. 9 A beauty instrument comprises a beauty instrument body 100 and a treatment head 200, wherein the treatment head 200 is connected to the beauty instrument body 100 via a signal line 300, and the treatment head 200 comprises a shell 201 and an ultrasonic transducer 202, wherein the shell 201 is in a cylindrical shape that is narrow at the top and wide at the bottom, and a metal massage head 203 is movably arranged on the inner side of the bottom of the shell 201, wherein the metal massage head 203 is a hollow structure and is made of stainless steel, and the ultrasonic transducer 202 is fixedly arranged inside the metal massage head 203, and a fixing block 204 is also arranged inside the shell 201 and above the metal massage head 203, wherein the metal massage head 203 and the fixing block 204 are elastically connected, and in a natural state, the bottom end of the metal massage head 203 extends out of the shell 201; when the power switch on the beauty instrument body 100 is turned on, the ultrasonic transducer 202 can convert electrical energy into sound energy and release energy in the form of ultrasonic waves.

[0037] Specifically, the number of the fixing blocks 204 is 2 to 4, and the fixing blocks 204 are evenly distributed on the inner surface of the housing 201. The bottom surface of the fixing blocks 204 is provided with a guide rod 205 along the vertical direction. Figure 8As shown, the guide rod 205 movably penetrates the top wall of the metal massage head 203, and a return spring 206 is also sleeved on the outside of the guide rod 205, and the two ends of the return spring 206 are respectively in contact with the bottom surface of the fixed block 204 and the top surface of the metal massage head 203. In a natural state, the return spring 206 is in a compressed state. That is, the metal massage head 203 can be raised and lowered along the direction of the guide rod 205, and under the action of the return spring 206, the metal massage head 203 is elastically connected to the bottom inner side of the housing 201.

[0038] Furthermore, a rubber storage ring 207 is fixedly mounted on the outer side of the bottom of the housing 201. Figure 4 As shown, the glue storage ring 207 is an internal hollow structure, and a plurality of glue outlet holes 208 are provided on the bottom wall of the metal massage head 203, and the glue outlet holes 208 are connected to the inside of the glue storage ring 207; the number of the glue outlet holes 208 is four, and the four glue outlet holes 208 are evenly distributed around the bottom surface of the metal massage head 203, and the inner surface of the metal massage head 203 and the glue outlet holes 208 are provided with glue outlet pipes 209, and the side wall of the shell 201 is penetrated with a glue supply elbow 210 corresponding to the glue outlet pipes 209, as shown in FIG. Fig. 9 As shown, one end of the glue supply elbow 210 extends into the glue storage ring 207, and the other end of the glue supply elbow 210 is connected to the glue outlet pipe 209 through the hose 211. The side wall of the metal massage head 203 is also provided with a movable opening 212 for the glue supply elbow 210 to pass through. Therefore, the glue outlet hole 208 is connected to the glue storage ring 207 through the glue outlet pipe 209, the hose 211 and the glue supply elbow 210. More specifically, the bottom of the metal massage head 203 is stepped, the middle position of the bottom surface of the metal massage head 203 is lower than its edge position, and a plurality of glue outlet holes 208 are located at the edge position of the bottom surface of the metal massage head 203. That is, when the bottom surface of the metal massage head 203 fits the user's skin, there is still a small gap between the glue outlet hole 208 and the user's skin, and the gap can facilitate the gel to be sprayed out from the glue outlet hole 208.

[0039] It is worth mentioning that, since the glue supply elbow 210 passes through the movable opening 212 on the side wall of the metal massage head 203, the glue supply elbow 210 always contacts the inner upper end of the movable opening 212 due to the presence of the return spring 206 in a natural state; when the metal massage head 203 is pressed downward, the metal massage head 203 moves upward relative to the housing 201, and the return spring 206 is further compressed. In addition, it should be noted that the metal massage head 203 is composed of a massage head body 2031 and a bottom wall 2032. Figure 6 As shown, the bottom wall 2032 is threadedly connected to the bottom of the massage head body 2031.

[0040] In addition, the housing 201 is also provided with a glue discharging assembly, which is used to drive the medium in the glue storage ring 207 to flow to the glue discharging hole 208. The glue discharging assembly includes a mounting sleeve 213, which is cylindrical in shape, and the bottom of the mounting sleeve 213 is threadedly connected to the inside of the glue storage ring 207. The mounting sleeve 213 is an internal hollow structure, and a plurality of driving rods 214 are movably arranged inside the mounting sleeve 213. The bottom ends of the plurality of driving rods 214 movably penetrate the bottom wall of the mounting sleeve 213 and are commonly connected with a piston ring 215, and the piston ring 215 is tightly fitted with the inner wall of the glue storage ring 207; the outer fixed sleeve of the driving rod 214 is provided with an annular flange 216, and the outer sleeve of the driving rod 214 is also provided with a driving spring 217, and the two ends of the driving spring 217 are respectively in contact with the annular flange 216 and the inner bottom surface of the mounting sleeve 213, and the driving spring 217 is in a compressed state in a natural state. That is, the driving spring 217 has a tendency to push the piston ring 215 to move upward; in addition, it should be noted that the bottom outer surface of the mounting sleeve 213 has an external thread, the top inner surface of the rubber storage ring 207 has an internal thread, and the bottom of the mounting sleeve 213 is screwed into the rubber storage ring 207.

[0041] Specifically, the glue discharging assembly also includes an electric push rod 218, such as Figure 4 As shown, the electric push rod 218 is fixedly arranged inside the housing 201, and the movable end of the electric push rod 218 is provided with a moving part 219, and the outer side of the moving part 219 is fixedly provided with a connecting rod 220. The side wall of the housing 201 is provided with a sliding opening 221 for the connecting rod 220 to pass through, and the outer end of the connecting rod 220 passes through the sliding opening 221 and is provided with a moving ring 222; the top of the driving rod 214 is provided with an extension part 223, and the top inner surface of the mounting sleeve 213 is provided with a strip opening 224 for the extension part 223 to pass through, and the extension part 223 passes through the strip opening 224 and extends under the moving ring 222. Therefore, when the electric push rod 218 controls the moving part 219 to move downward, the moving ring 222 can push the extension part 223 to move downward synchronously, and then push the piston ring 215 to move downward; when the moving ring 222 rises, then under the action of the driving spring 217, the piston ring 215 can automatically rise and reset.

[0042] Furthermore, a cross mounting block 225 is provided inside the housing 201, and an electric push rod 218 is fixedly connected to the bottom surface of the cross mounting block 225. A controller 226 of model TLE5205-2 is also provided inside the housing 201, and a signal output end of the controller 226 is connected to the electric push rod 218. A micro switch 227 is provided inside the housing 201, and the micro switch 227 is located between the metal massage head 203 and the fixed block 204, and the micro switch 227 is electrically connected to the controller 226. An inclination sensor 228 of model SCL3300-D01 is provided on the top surface of the cross mounting block 225, and a signal output end of the inclination sensor 228 is connected to the controller 226. A solenoid valve 229 is also provided on the rubber outlet pipe 209, and a signal output end of the controller 226 is connected to the solenoid valve 229. When the metal massage head 203 is pressed downward with a little force, the metal massage head 203 rises relative to the housing 201, so that the top wall of the metal massage head 203 contacts the micro switch 227, and the micro switch 227 transmits an electrical signal to the controller 226. The controller 226 controls the electric push rod 218 to start, thereby moving the piston ring 215 downward to squeeze out the gel.

[0043] It is worth mentioning that the inclination sensor 228 is used to monitor the inclination of the treatment head 200. When the treatment head 200 maintains a vertical posture, the solenoid valves 229 on the four glue outlet pipes 209 are all in an open state. At this time, when the metal massage head 203 is pressed, glue can be discharged from the four glue outlet holes 208; when the treatment head 200 is tilted toward one side of a glue outlet hole 208 and the metal massage head 203 is pressed, the solenoid valve 229 corresponding to the glue outlet hole 208 is still in an open state, and the glue outlet hole 208 can discharge glue outward, while the remaining solenoid valves 229 are all in a closed state and cannot discharge glue. It should be noted that the tilt threshold of the tilt sensor 228 toward any glue outlet hole 208 is 10°, that is, when the tilt angle of the treatment head 200 toward any direction does not exceed 10°, it is regarded as a vertical posture, and at this time, the four solenoid valves 229 are all in the open state; conversely, when the tilt angle of the treatment head 200 toward a certain direction exceeds 10°, only the glue outlet hole 208 corresponding to this direction is in the open state.

[0044] Embodiment 2: This embodiment provides a control method for a beauty instrument, which is applicable to a beauty instrument in Embodiment 1, and includes the following steps:

[0045] Turn on the power switch on the beauty instrument body 100, the operator holds the treatment head 200 and points the metal massage head 203 at the user's skin, then the ultrasonic transducer 202 can emit ultrasonic waves, and directly act on the human skin through the metal massage head 203;

[0046] In the initial state, the skin is relatively dry and gel needs to be applied to the skin surface. At this time, the operator can keep the treatment head 200 in a vertical state and press it down slightly, so that the four gel outlet holes 208 can spray gel outward at the same time;

[0047] The operator selects multiple points on the user's massage area, and presses down once on each point, so that multiple gel spraying points are formed on the user's massage area, and then uses the metal massage head 203 to evenly coat the gel at the multiple points;

[0048] When the massage area gradually dries, the operator holds the treatment head and tilts it toward the dry area and presses it downward, and then a glue outlet hole 208 aimed at the dry area can be sprayed separately, so that the dry area can be re-moistened. The advantage of this embodiment is that, compared with the traditional ultrasonic beauty instrument, the treatment head 200 in this embodiment has both massage and glue application functions, and no additional glue application tools such as brushes are required, which helps to simplify the massage operation steps. Secondly, during the massage process, when the skin surface gradually dries, it is not necessary to stop the massage and apply glue, but it can be directly applied by pressing, which further helps to improve the massage efficiency and operation fluency. Finally, the tilting treatment head 200 can realize the function of directional glue discharge. The effect is that during the massage process, since the surface of the human skin is not absolutely flat, after a period of massage, the skin surface is prone to uneven distribution of dry areas. In this way, when the treatment head 200 slides and rubs along the skin surface, when encountering a dry area, the treatment head 200 can be directly tilted and pressed downward to realize the directional glue spraying function. On the one hand, the glue spraying direction can be controlled to improve the accuracy of glue spraying, and on the other hand, it also helps to avoid the waste of gel.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
