For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] Please refer to Figure 1 The embodiments of the present application provide a laser acne-removing patch, which comprises a power supply 2, a load 3 comprising a laser chip 31, a housing 1, and an adhesive patch 4.

[0041] The laser chip 31 is used to emit at least one waveband of laser;

[0042] The power supply 2 is electrically connected with the load 3, and the power supply 2 is used to supply power to the load 3;

[0043] The load 3 and the power supply 2 are arranged inside the shell 1, and the skin-close end 12 of the shell and the skin-close end of the adhesive patch 4 are provided with small holes. The laser emitted by the laser chip 31 is irradiated to the treatment area through the small holes. The skin-close end of the adhesive patch 4 is connected to the skin-close end 12 of the shell.

[0044] At present, the portable and miniaturized medical and cosmetic products on the market are all based on LED light sources. The LED light spectrum range is wide, the effective wavelength proportion is low, the divergence angle is large, and the energy density is low. However, the laser has the advantages of concentrated light spectrum, high effective wavelength proportion, small divergence angle, and high energy density. Therefore, in order to ensure the treatment effect, the laser acne-removing patch of the embodiment of the present application uses the laser emitted by the laser chip 31 as the light source. Compared with the LED light source, the laser used in the embodiment of the present application can achieve the same treatment effect in a shorter time. It should be noted that, in order to ensure the acne-removing effect of the laser acne-removing patch of the present application, the wavelength band of the laser emitted by the laser chip 31 of the embodiment should be the wavelength band that has a treatment effect on acne, such as the red light wavelength band of 400mm-480mm and / or the blue light wavelength band of 630mm-850mm, which is not limited here. The laser chip 31 in the present application exists as the load 3 of the entire laser acne-removing patch, and there is an electrical connection between the load 3 and the power supply 2, so as to supply power to the power-consuming devices in the load 3, such as the laser chip 31, the driving chip 33, the single-chip microcomputer 32, etc. in the load 3.

[0045] In addition, it should be noted that the power supply 2 of the present application can use a farad capacitor and a button cell and other light weight power supply devices. Among them, the button cell has higher safety compared with the lithium battery, and is suitable as the power supply 2 of the laser acne-removing patch which directly contacts the skin.

[0046] The above-mentioned load 3 and power supply 2 are arranged inside the shell 1, and the skin-close end 12 of the shell and the skin-close end of the adhesive patch 4 are connected. In actual application, in order to ensure that the laser emitted by the laser chip 31 can be accurately and undisturbedly guided to the treatment area, the material of the skin-close end 12 of the shell and the material of the adhesive patch 4 need to be selected, or the skin-close end 12 of the shell and the adhesive patch 4 need to be treated. Figure 2 The light bead of the laser chip 31 shown in the figure can accurately and undisturbedly guide the emitted laser to the treatment area. In addition, the material of the skin-close end 12 of the shell and the material of the adhesive patch 4 need to be selected, or the skin-close end 12 of the shell and the adhesive patch 4 need to be treated.

[0047] For example, small holes can be provided on the skin-close end 12 of the shell and the adhesive patch 4 to allow the laser emitted by the laser chip 31 to directly irradiate to the treatment area through the small holes; or the skin-close end 12 of the shell and the adhesive patch 4 can be selected to have a material with high light transmittance, etc. which is not limited here.

[0048] In addition, in order to minimize the volume of the entire laser acne-removing patch, the entire shell 1 can also be arranged to have a similar shape to the outer contour of the power supply 2.

[0049] It should be noted that the small hole provided by the proximal skin end 12 of the shell and the adhesive patch 4 makes the proximal skin end of the entire laser acne-removing patch form a recess towards the interior of the shell 1, please refer to Figure 2 , which is sufficient to accommodate or include the acne of the treatment area. In addition, in order to ensure that a power supply circuit is formed between the power supply 2 and the load 3, a metal spring 7 as shown in Figure 1 or other conductive elements should also be provided.

[0050] In the embodiment of the present application, the entire laser acne-removing patch only includes the power supply 2, the load 3 including the laser chip 31, the shell 1 and the adhesive patch 4, wherein the shell 1 is only used to wrap the circuit board 9 carrying the laser chip 31 and the power supply 2, both of which are very small in volume and weight. Therefore, in the case that the proximal skin end 12 of the shell is connected to the distal skin end of the adhesive patch 4, the proximal skin end of the adhesive patch 4 can also be pasted to the skin surface, so that the laser emitted by the laser chip 31 after pasting can accurately irradiate the treatment area, and the user only needs to paste the laser acne-removing patch to the skin surface and make the laser cover the treatment area, without the need for the user to hold it during the entire subsequent treatment process, thereby reducing the user's use cost.

[0051] In some specific implementations, in order to improve the controllability of the user to the treatment process, the laser acne-removing patch of the embodiment further includes the circuit board 9 and the switch 5 provided on the outer side of the shell 1, and the load 3 further includes: the single-chip microcomputer 32 provided on the circuit board 9, the switch 5 is electrically connected to the single-chip microcomputer 32, and the circuit board 9 is electrically connected to the power supply 2; if the switch 5 is in an open state, the single-chip microcomputer 32 is used to make the power supply 2 supply power to the laser chip 31; if the switch 5 is in a closed state, the single-chip microcomputer 32 is used to make the power supply 2 stop supplying power to the laser chip 31.

[0052] In order to use the introduced switch 5 to improve the controllability of the user to the treatment process, the laser acne-removing assembly of the embodiment of the present application also needs to introduce the circuit board 9, and the single-chip microcomputer 32 needs to be introduced into the load 3, and the single-chip microcomputer 32 is configured with a software control algorithm for regulating the voltage and / or current supplied to the laser chip 31 according to different states of the switch 5. Specifically, the switch 5 can be provided at a position on the outer side of the shell 1 as shown in Figure 3 or at a position such as the top of the shell 1, which is not limited in the embodiment of the present application. It can be understood that, in order to increase the compactness of the laser acne-removing patch of the present application in structure, the load 3 in the embodiment of the present application can be provided on the circuit board 9. In actual application, the arrangement of each load 3 on the circuit board 9 can refer to the embodiment shown in Figure 7 . It should be noted that there are many specific implementation manners for arranging each load 3 of the present application on the circuit board 9, Figure 7 which are only exemplary and are not limited to the implementation manner of the present application.

[0053] The introduction of the switch 5 allows the user to freely adjust the working state of the laser acne-removing patch. For example, if the switch 5 is in the on state, the single-chip microcomputer 32 is configured to supply power to the laser chip 31 from the power supply 2. That is, if the switch 5 is in the on state, the laser chip 31 in the laser acne-removing patch will emit laser under the control of the single-chip microcomputer 32 to start treating the treatment area covered thereby. If the switch 5 is in the off state, the single-chip microcomputer 32 is configured to stop supplying power to the laser chip 31 from the power supply 2. That is, if the switch 5 is in the off state, the laser chip 31 in the laser acne-removing patch will stop emitting laser under the control of the single-chip microcomputer 32 to suspend the laser treatment.

[0054] It can be understood that, in addition to being used to control whether the laser chip 31 emits laser, the switch 5 can also be used to adjust different working modes of the laser chip 31 in the on state of the switch 5, so that the single-chip microcomputer 32 controls the voltage and / or current supplied to the laser chip 31 to make it emit laser of different intensities and / or different wavebands, to realize switching or selection of working modes. The switching of different working modes can be realized by different pressing modes of the switch 5, and the different pressing modes include but are not limited to: pressing duration, pressing force, and / or pressing frequency. In actual application, the working modes can be a mode for eliminating acne marks and a mode for acne removal and inflammation reduction. In the mode for eliminating acne marks, the laser chip 31 can emit laser of 660 nm and 850 nm, and in the mode for acne removal and inflammation reduction, the laser chip 31 can emit laser of 475 nm and 660 nm. It should be noted that the wavebands and working modes described in this embodiment are only exemplary, and in fact, the laser chip 31 of this embodiment can be set to emit laser of any waveband and any number in any working mode according to the treatment needs, which is not limited here.

[0055] In addition, in order to increase the use time of the product, a low-power single-chip microcomputer can be selected to reduce the power consumption of the laser acne-removing patch in the off state. The low-power single-chip microcomputer of this embodiment has a current of only a few microamperes in the off state, compared with the current of milliamperes in the off state of an ordinary single-chip microcomputer. The use of a low-power single-chip microcomputer can effectively increase the endurance of the laser acne-removing patch of this application.

[0056] Further, in addition to reducing the overall power consumption of the laser acne-removing patch by selecting a low-power single-chip microcomputer, the load 3 of the present embodiment further comprises a drive chip 33 disposed on the circuit board 9 in the case of limited power supply 2. The drive chip 33 is disposed on the power supply circuit between the power supply 2 and the laser chip 31, so that the drive chip 33 can well control the current flowing through the laser chip 31. Therefore, the drive chip 33 can adjust the duty cycle of the current flowing through the laser chip 31 by means of integrated circuit intercommunication (I2C) and pulse width modulation (PWM), without the laser chip 31 continuously emitting light sources throughout the entire work flow. The above-mentioned means can reduce the overall power consumption of the laser acne-removing patch without affecting the treatment effect. Among them, I2C is a bus protocol for communication between chips, and PWM is a way to adjust the output signal by controlling the width of the pulse signal. Under the regulation of the duty cycle, the periodic laser emitted by the laser chip 31 of the present embodiment has a relatively fixed average light power in each cycle to ensure the treatment effect at different times.

[0057] Further, in addition to reducing the overall power consumption of the laser acne-removing patch by selecting a low-power single-chip microcomputer and adjusting the duty cycle of the current flowing through the laser chip 31 by the drive chip 33, the present embodiment can further introduce a cutoff element 34 disposed on the power supply circuit. The cutoff element 34 can physically disconnect the circuit connection between the power supply 2 and the power-consuming hardware in the load 3 such as the drive chip 33 and the laser chip 31 except the single-chip microcomputer 32 after the switch 5 is turned off, and can reduce the power consumption of the entire laser acne-removing patch to microamperes after shutdown. Among them, the cutoff element 34 can be a triode or a field effect transistor or any device that can achieve the above-mentioned effect.

[0058] In actual application, if a simple combination of LED + resistor (R) + power supply (V) is used to provide light source, the current through the LED should be V / R, and the current is proportional to the light power. During the treatment process, as the battery capacity decreases, the voltage of the power supply will also gradually decrease, and the current through the LED will also decrease. The instability of the current will cause the light power provided by the light source to decrease during the entire treatment process. That is, over time, without replacing the battery, the treatment effect is gradually deteriorating.

[0059] Therefore, the driving chip 33 in the embodiment of the present application is further used to control the current value on the power supply circuit to be a desired value, so as to control the optical power of the laser. It can be understood that the current on the power supply circuit is the current flowing through the laser chip 31, and the optical power of the laser emitted by the laser chip 31 is related to the current flowing through the laser chip 31. Therefore, if the current value on the power supply circuit is controlled to be a desired value, it is equivalent to control the optical power of the laser emitted by the laser chip 31 to be a specific value.

[0060] In the embodiment of the present application, if the driving chip 33 is not used to adjust the duty cycle, the current value here is the real-time current value on the power supply circuit; if the driving chip 33 is further used to adjust the duty cycle, the current value here can be the average current in a period. In this way, the optical power of the laser emitted by the laser chip 31 is controlled to be a stable level, and the treatment effect of the laser acne-removing patch is ensured at all times, avoiding the influence of the voltage drop on the optical power of the laser emitted by the laser chip 31.

[0061] In other implementations, the laser acne-removing patch in the embodiment of the present application can also use a power supply 2 with a cut-off voltage greater than the driving voltage of the laser chip 31. In this way, it can be ensured that the power in the power supply 2 is fully utilized, and the situation that the power supply 31 cannot be powered due to insufficient voltage before the battery power is consumed does not exist. In addition, the laser acne-removing patch in the embodiment of the present application further includes an anti-reverse connection element 8 arranged between the power supply 2 and the load 3, so as to avoid damage to the load 3 such as the laser chip 31, the single-chip microcomputer 32, and the driving chip 33 caused by reverse connection of the power supply 2. It should be noted that the electrical connection relationship between each load 3, the power supply 2, and the switch 5 in the embodiment of the present application can be referred to the connection relationship shown in FIG. 1. Figure 4 .

[0062] In addition, the shell 1 of the present application has a distal skin end 11 and a proximal skin end 12, which can be integrally formed or detachably connected. If detachable connection is adopted, the user can replace the power supply 2 in the shell 1 by detaching the distal skin end 11 and the proximal skin end 12 of the shell, thereby increasing the service life of the product. Then, the proximal skin end 12 of the shell of the present application can also use flexible materials to increase the adhesion effect of the entire laser acne-removing patch to the skin surface, and further improve the treatment effect. It should be noted that since the adhesive patch 4 is connected by adhesion, the adhesive patch 4 is a replaceable consumable, and the user can replace it at any time according to the needs, so as to increase the service life of the entire laser acne-removing patch. Finally, in order to improve the user experience, the proximal skin end of the laser acne-removing patch in the embodiment of the present application can be divided into, for example, Figure 6 and Figure 1The support 121 can consider using a material with a certain hardness to protect the hardware inside the shell 1. The shielding piece 123 can consider using a non-transparent material to shield the load 3, the circuit board 9, the power supply 2 and other devices inside the shell 1. The flexible piece 122 can adopt a skin-friendly material such as silica gel, thermoplastic elastomer (TPE) material or thermoplastic rubber (TPR) material to reduce the discomfort of skin adhesion.

[0063] In actual application, considering that the air flow in the space formed among the shell 1, the adhesive 4 and the treatment area is slow, in order to make the sweat generated in the space better discharged, and avoid the adhesive 4 from being pasted due to the sweat accumulation of the treatment area, the skin-close end 12 of the shell in the embodiment of the application is provided with a sweat discharge groove 6, which is used to communicate the space formed among the shell 1, the adhesive 4 and the treatment area with the outside.

[0064] Through the introduction of the sweat discharge groove 6, the sweat generated in the space formed among the shell 1, the adhesive 4 and the treatment area is better discharged, and the air flow of the treatment area is enhanced. Specifically, the shape of the sweat discharge groove 6 can refer to the shape as shown in Figure 5 which is adapted to the cross-sectional shape of the shell 1 perpendicular to the laser emission direction, and is provided as a plurality of concentric annular grooves, and the plurality of annular grooves are communicated through the communication grooves, so as to ensure that the space formed among the shell 1, the adhesive 4 and the treatment area is not completely closed, and thus ensure the smooth discharge of the sweat of the treatment area, avoid the adhesive 4 from being pasted due to the sweat accumulation of the treatment area, and thus avoid the problem of treatment interruption.

[0065] On the basis of the foregoing embodiment, in another implementation mode, in order to solve the sweat or water vapor generated by the treatment area, the adhesive 4 can also be made of a sweat-absorbing material, so that the adhesive 4 is also used to absorb the sweat generated by the treatment area, and the stability of the whole treatment process is increased.

[0066] The above embodiments are only used to illustrate the technical solutions of the application, and not to limit them.
