[0024] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, a handheld cosmetic medical laser includes a housing 1, a laser 7, a focusing cover 3, a circuit board, a power switch 2, an indicator light 4, and a tail section 6.

[0027] The housing 1 is handle-shaped, with a grip 101 and an output head 102 arranged sequentially along the axial direction. The grip 101 is designed in an ergonomic shape for easy holding and operation by the user. The output head 102 is slightly larger than the grip 101 and is used to house the laser 7 and its related components.

[0028] Laser 7 is housed inside output head 102, such as Figure 2 As shown, the output section 70 of the laser 7 extends downward to form an output head 102. The laser 7 generates laser light of a specific wavelength through its internal structure for use in cosmetic medical treatments.

[0029] The focusing cover 3 is fitted around the output section 70 and is fixedly connected to the housing of the output head 102. The focusing cover 3 is made of a special material, which can effectively prevent the laser from scattering in all directions, improve the laser focusing effect, and protect the safety of the user and surrounding personnel.

[0030] The circuit board is housed inside the casing 1 and is electrically connected to the laser 7, indicator light 4, and power switch 2. The circuit board is equipped with a control chip, a power management module, and a signal processing circuit, which are used to control the laser's operating status, power output, and safety protection functions.

[0031] The handle 101 has a tail 6 at the end furthest from the output head 102, which is used to secure the connecting cable. This design makes the connection between the connecting cable and the device more secure, preventing the device from losing power or the signal from being interrupted due to the connecting cable becoming loose during use.

[0032] The top of the output head 102 is equipped with an indicator light 4, which is electrically connected to the circuit board and is used to display the working status of the laser. The indicator light 4 uses different colors or flashing patterns to indicate whether the device is powered on, whether the laser is working, the battery status, and other information, so that users can understand the working status of the device in real time.

[0033] Decorative parts 5 are symmetrically arranged on the left and right sides of the output head 102, and the decorative parts 5 are detachably connected to the outer shell of the output head 102. The decorative parts 5 not only enhance the aesthetics of the device, but can also be replaced according to different usage scenarios or user preferences, increasing the personalization options of the product.

[0034] The power switch 2 is located below the connection between the output head 102 and the handle 101, and extends through the wall of the housing 1 along its thickness. This design allows the user to easily operate the power switch 2 with their thumb while holding the device, improving ergonomic comfort.

[0035] like Figure 3 As shown, the power switch 2 includes a button 2-1, a limiting member 2-2, and a switch member 2-3. A groove 20 is provided on the side of the button 2-1 facing the interior of the housing 1. The limiting member 2-2 is embedded in the groove 20 to prevent the button 2-1 from shifting circumferentially along the housing, ensuring that the button 2-1 can only move in a preset direction. The switch member 2-3 is housed within the limiting member 2-2 and abuts against the push-button switch on the circuit board, used to connect or disconnect the laser power supply circuit. When the user presses the button 2-1, the switch member 2-3 moves accordingly and triggers the push-button switch on the circuit board, thereby controlling the laser's on or off state.

[0036] The limiting member 2-2 is interference-fitted with the groove 20, and the end of the limiting member 2-2 facing the inside of the housing 1 is provided with a radial flange, which cooperates with the limiting shoulder of the inner wall of the housing. This structural design can effectively prevent the button 2-1 from falling off and improve the service life and reliability of the power button 2.

[0037] The laser 7 is equipped with a water inlet 701 and a water outlet 702. The water inlet 701 and the water outlet 702 are respectively connected to an external cooling circulation device through fluid pipelines, forming an internal water-cooled heat dissipation channel for the laser 7. This water-cooling system design can effectively reduce the heat generated by the laser during operation, keep the laser within the optimal operating temperature range, extend the service life of the equipment, and improve the stability of laser output.

[0038] The inlet 701 and outlet 702 are arranged symmetrically along the radial direction of the laser 7, and their central axes are coplanar. This design reduces the dead zone of coolant flow and improves heat dissipation uniformity. After entering through the inlet 701, the coolant can flow evenly through all heat source areas inside the laser 7, and then exit through the outlet 702, forming an efficient heat exchange cycle. This ensures that the temperature of all parts of the laser is balanced and avoids performance degradation or damage caused by local overheating.

[0039] During use, the operator holds the handle 101 and presses the power switch 2 to start the device. The indicator light 4 illuminates, indicating that the device is on. The laser is emitted from the output section 70 and focused by the focusing cover 3 before acting on the treatment area. Simultaneously, the water cooling system continuously circulates coolant through the inlet 701 and outlet 702 to maintain the operating temperature of the laser 7. After treatment, pressing the power switch 2 again turns off the device, and the indicator light 4 goes out.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
