[0001] The utility model relates to the technical field of lasers, in particular to a laser with power detection and display functions. Background Art

[0002] A laser is a device that can emit laser light. The intensity of the laser light emitted by the laser is generally controlled by its internal control circuit. However, due to the influence of factors such as the chip that carries the control circuit, the ambient temperature, or the aging of the device, there is a certain degree of error in the performance during actual use. Therefore, in order to avoid the influence of this part of the error, the laser needs to be calibrated before leaving the factory.

[0003] However, in actual applications, due to different use environments, fiber transmission efficiencies, and subsequent maintenance, there will still be a deviation between the actual intensity of the emitted laser and the laser intensity at the factory. Generally, this deviation does not affect the use effect, but in the medical field and other fields, the accuracy requirements of the equipment are high, so this deviation will lead to unsatisfactory medical effects and even cause further injuries to patients.

[0004] The ability of the lasers on the market to monitor the actual laser intensity may easily lead to the situation that the actual intensity of the laser emitted by the laser when in use is inconsistent with the set value. Therefore, a laser with power detection and display function is proposed to solve the above-mentioned problem. Utility Model Content

[0029] See also Figure 1 , Figure 4 and Figure 5 , lasers with power detection and display functions, including:

[0030] A laser body 1; and

[0031] The mounting shell 2 comprises a top cover 21 and a bottom shell 22. The top cover 21 is arranged at one end of the laser body 1 and is interconnected with the laser body 1. A mounting groove 23 is arranged at the top end of the top cover 21. A display screen 6 is arranged inside the mounting groove 23. The top cover 21 and the bottom shell 22 are connected to each other by screws. The top cover 21 and the bottom shell 22 are arranged on opposite sides thereof with a card slot 24, a positioning slot 25, a fixing slot 26 and a connecting slot 27 that are interconnected. A routing line 28 is arranged on one side of the top cover 21 and the bottom shell 22 close to the laser body 1. A routing groove 29 is arranged on the upper surface of the routing line 28.

[0032] Based on the above, the laser body 1 can emit laser and control the intensity of the laser through the internal circuit. The laser body 1 is a traditional laser and is a mature existing technology. Therefore, its specific internal structure and principle are not described here. The mounting groove 23, the card slot 24, the positioning groove 25, the fixing groove 26, the connecting groove 27 and the wiring groove 29 respectively play a role in the display screen 6, the spectroscope 7, the protective lens 4, the controller 5 and the heat exchange block 3.

[0033] like Figure 2-Figure 3 As shown, the protective lens 4 and the beam splitter 7 are both arranged inside the mounting shell 2, and the beam splitter 7 is arranged between the protective lens 4 and the laser body 1;

[0034] The slot 24 is provided with a beam splitter 7 inside, the positioning slot 25 is provided with a protective lens 4 inside, and the laser body 1, the beam splitter 7 and the protective lens 4 are on the same straight line;

[0035] Based on the above, the protective lens 4 plays a role in protecting the device, preventing foreign matter such as dust from the outside from entering the interior of the mounting shell 2, and the beam splitter 7 plays a role in splitting a laser beam into two laser beams, at which time the sum of the intensities of the two laser beams is equal to the intensity of the original laser.

[0036] like Figure 1-Figure 3As shown, the detection unit is arranged inside the mounting shell 2 and is electrically connected to the laser body 1, and includes a controller 5 and an electric thermal pile sensor 8. The controller 5 is arranged inside the fixing groove 26, and the electric thermal pile sensor 8 is arranged on the surface of the controller 5. The controller 5 and the electric thermal pile sensor 8 are electrically connected to each other. A cable is arranged at one end of the controller 5, and the cable is arranged inside the wiring groove 29 and is connected to the laser body 1.

[0037] A display screen 6 is disposed on the upper surface of the top cover 21 and is electrically connected to the controller 5. The interior of the mounting groove 23 is provided with a display screen 6 electrically connected to the controller 5;

[0038] Based on the above, the controller 5 can select a microcontroller of model RX6600, which mainly compares and calculates the data transmitted from the electrothermal stack sensor 8 and adjusts the intensity of the emission of the laser body 1. The electrothermal stack sensor 8 only plays the role of detecting the intensity of the light beam, which is the basic working standard of this type of sensor. Therefore, its specific model and structure are not described here, and the data is displayed on the display screen 6 through the controller 5.

[0039] like Figure 2 and Figure 6 As shown, the heat exchange block 3 is arranged inside the mounting shell 2 and extends to the outside of the mounting shell 2. The heat exchange block 3 includes an I-shaped block 31. The I-shaped block 31 is arranged inside the connecting groove 27 and extends to the outside of the mounting shell 2. Heat exchange wings 32 are arranged on both sides of the I-shaped block 31.

[0040] Based on the above, the heat exchange block 3 has a heat exchange effect. When the controller 5 is working, heat is generated. The heat is exchanged with the heat exchange block 3 in the form of heat exchange, and then the cooling effect is achieved by transferring the heat to the external environment to ensure that the controller 5 can work normally.

[0041] In actual use, the embodiment emits laser light through the laser body 1, and the emitted laser light is divided into two beams by the beam splitter 7. One beam of light passes through the beam splitter and the protective lens and then is emitted. This beam of light is used for laser treatment, and the other beam of light is refracted to the electric thermal pile sensor, and then the intensity of the beam is measured. Since the beam splitter 7 remains unchanged, the intensity ratio of the two separated beams to the total beam remains unchanged. For example, when one beam of light is 50% of the total beam intensity, the other beam is also 50%. When the total beam intensity changes, the proportion remains unchanged, but the actual intensity changes.

[0042] Therefore, by detecting the intensity of the other beam of light, the intensity of the beam used for treatment can be understood, and by comparing the intensity with the set value, it can be known whether the intensity meets the requirement. If it does not meet the requirement, the controller 5 controls the laser body 1 to make adjustments to ensure that the laser intensity is qualified.

[0043] When the laser intensity is detected by the electric heat pile sensor 8, its specific value is displayed on the display screen 6 under the action of the controller 5 for easy reading;

[0044] Compared with traditional lasers, this laser improves on the structure of traditional lasers, splitting the laser beam into two beams and monitoring the intensity of the separated beams so that the intensity of the beam used for treatment reaches the set value, ensuring that the actual intensity of the laser is consistent with the set value, thereby avoiding secondary damage to the patient caused by the laser during the medical process.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
