[0021] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] This specific embodiment provides a picosecond laser to solve the technical problem in the prior art that the heat generated during laser treatment may cause thermal damage to the skin.

[0023] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the utility model as set forth in the claims.

[0024] Reference Figure 1-Figure 2 The utility model provides a picosecond laser, which is widely used in the field of beauty for treatments such as skin rejuvenation, freckle removal, and tattoo removal. However, the heat generated during laser treatment may cause thermal damage to the skin. In order to solve this problem, the present application document provides a picosecond laser including a main body 1, on which a laser device 2 and a compressor air cooling system 3 are provided. The compressor air cooling system 3 is used to generate cold air, wherein the cold air is sprayed on the human skin, thereby reducing the burning of the skin by the laser device 2, and thereby reducing the degree of discomfort of people. Specifically, the compressor air cooling system 3 includes an air outlet pipe 31 provided on the main body 1, a bracket 32 ​​supporting the air outlet pipe 31, a cooling head 33 installed at one end of the air outlet pipe 31, a blower 37, a compressor 34, a condenser 35, and an evaporator 36 that are sequentially arranged in the main body 1 and connected to each other. The compressor 34 is the starting point of the refrigeration cycle. Its function is to extract low-temperature and low-pressure refrigerant vapor and compress it into high-temperature and high-pressure gas, and then transport the high-temperature and high-pressure gas to the condenser 35. The main function of the condenser 35 is to release heat, cool the refrigerant gas and condense it into liquid. In this process, the temperature and pressure of the refrigerant are reduced, and the condensed liquid refrigerant flows into the evaporator 36. In the evaporator 36, the refrigerant absorbs heat and evaporates into a gaseous state, wherein a blower 37 is installed on one side of the evaporator 36. The blower 37 brings outside air into the evaporator 36 for cooling, and the cooled gas is blown toward the cooling head 33. The bracket 32 ​​includes a plurality of connecting rods arranged in sequence, and the two adjacent connecting rods can rotate to adjust the position of the outlet of the air outlet pipe 31 so that the cold air blown out by the cooling head 33 is aligned with the working position of the laser head of the laser device 2. In this way, when people use it, they can adjust the bracket 32 ​​to change the position of the cooling head 33 so that the cooling head 33 can be aligned with the working position of the laser head of the laser device 2, thereby reducing the heat generated by the operation of the laser head.

[0025] With this arrangement, the picosecond laser technology, with its extremely short pulse width and high peak power, can accurately act on the deep layers of the skin, effectively destroying melanocytes and crushing pigment particles. This highly efficient treatment method can significantly shorten the treatment time and improve treatment efficiency. The compressor air cooling system 3 can quickly lower the skin surface temperature by ejecting low-temperature airflow, reducing the direct thermal damage of the laser energy to the skin. This immediate cooling effect helps protect the skin and reduces the risks during treatment. At the same time, the compressor air cooling system 3 can also reduce the thermal damage of the laser energy to the surrounding tissues to a certain extent, further improving the safety of the treatment. The instant cooling function of the compressor air cooling system 3 can significantly alleviate the burning and pain caused by laser treatment, making the patient feel more comfortable during the treatment process. This improvement in comfort helps to reduce the patient's tension and improve the acceptance of the treatment.

[0026] Furthermore, picosecond lasers not only remove pigment but also stimulate collagen regeneration and repair deep within the skin. This skin-restoring effect helps improve skin quality, making it firmer and smoother. Picosecond laser devices with a cold air function are suitable for a variety of skin types and conditions, including melasma, freckles, photodermatitis, café-au-lait spots, and age spots. Their wide applicability holds significant market potential in the medical aesthetics field. The device is also easy to operate, making it easy for healthcare professionals to master and quickly adapt. This helps reduce operator errors and improve treatment quality.

[0027] To further optimize the solution, in order to reduce the temperature around the condenser 35, the compressor air cooling system 3 also includes a fan 38. The fan 38 is installed on one side of the condenser 35 to blow away the heat released by the condenser 35. The temperature around the condenser 35 is reduced, thereby ensuring that the condenser 35 can dissipate heat quickly and achieve a better heat dissipation effect.

[0028] A further optimization solution is provided, in which an outer layer is provided on the outside of the evaporator 36, and a space for air circulation is formed between the outer layer and the outer side of the evaporator 36, and two openings are provided on the outer layer, one of which is connected to the blower 37 so that the blower 37 can continuously provide gas into the space. At the same time, the other opening is connected to the air outlet pipe 31, so that the air enters the space under the drive of the blower 37. Since the liquid refrigerant in the evaporator 36 absorbs heat and turns into gas, the temperature of the air in the space is reduced, so that the temperature of the gas ejected from the cooling head 33 is relatively low, thereby achieving the purpose of reducing the temperature.

[0029] A further optimization plan, in order to facilitate the simultaneous control of the laser equipment 2 and the compressor air cooling system 3, also includes a control system. The control system is electrically connected to the compressor air cooling system 3 and the laser equipment 2 to control the simultaneous start and stop of the compressor air cooling system 3 and the laser equipment 2. In this way, when the laser equipment 2 is working, the compressor air cooling system 3 is also started, so that people can start them at the same time when using them.

[0030] A further optimized solution is that the laser device 2 also includes a laser 21, a light guide arm 22, and a controller. The controller controls the opening and closing of the laser 21. The laser 21 is connected to the light guide arm 22. The controller is electrically connected to the control system, that is, the control system gives the controller a signal, and the controller controls the operation of the laser 21. The laser 21 generates heat energy and emits it outward through the light guide arm 22 to treat the skin.

[0031] To further optimize the solution, in order to facilitate the control of the size of the air outlet of the cooling head 33, the blower 37 of the compressor air cooling system 3 is electrically connected to the control system, and the control system controls the speed of the blower 37 when it is turned on. In this way, the size of the air outlet of the cooling head 33 can be adjusted according to different conditions.

[0032] To further optimize the solution, in order to facilitate people to push the main body 1, a universal wheel 12 is set at the bottom of the main body 1.

[0033] To further optimize the solution, an emergency stop button 11 is provided on the main body 1. The emergency stop button 11 is electrically connected to the laser equipment 2 and the compressor air cooling system 3. When an emergency occurs, the emergency stop button 11 can be directly pressed.
