[0002] The laser of a medical laser therapy machine is the core component of laser medical equipment. When it works normally, the cleanliness of the space where the laser transmission path is located inside the laser is very high. Any tiny dust, powder, suspended particles in the air that break into the light path will destroy the normal transmission of light, causing light scattering, reflection and other deflection phenomena, resulting in energy loss and affecting the output power of the laser. Especially for high-power lasers, the deflected laser can easily burn out optical devices in the light path, such as lenses, optical fibers, etc.

[0003] To solve this problem, the laser light output window needs to be equipped with a dustproof device to prevent dust from entering the laser and damaging the normal transmission of the optical path. The optical fiber connector of the laser therapy machine light output window is a precision device. Damage such as bumps and collisions can easily cause abnormal transmission of the optical path. Therefore, the structure of the laser therapy machine light output window is generally concave to prevent damage to the optical fiber connector due to bumps and collisions. The concave design of the light output window structure results in a small operating space for connecting the optical fiber, and the design of the dustproof device also needs to meet the limitations of the small space.

[0048] Optionally, the shielding assembly 1 includes a first baffle 11 and a second baffle 12, the connection ends of the first baffle 11 and the second baffle 12 are coaxially rotatably connected to the base 3, and the free ends of the first baffle 11 and the second baffle 12 always maintain a closing tendency to shield the window 100. A limiting groove 32 and a rotating shaft 33 are provided on the base 3, and the limiting groove 32 is used to limit the opening angle of the first baffle 11 and the second baffle 12. The first baffle 11 and the second baffle 12 are provided with a rotating hole 14 that cooperates with the rotating shaft 33, so that the first baffle 11 and the second baffle 12 can rotate around the rotating shaft 33. When the first baffle 11 and the second baffle 12 are placed vertically, the first baffle 11 and the second baffle 12 clamp the transition section 211 under the action of gravity to maintain the closing tendency. When the first baffle 11 and the second baffle 12 are not placed vertically, a torsion spring is provided at the rotation position of the first baffle 11 and the second baffle 12 to keep the first baffle 11 and the second baffle 12 always in a closed trend.

The elastic clip may be U-shaped, and the inner side of the U-shaped elastic clip 5 is respectively in contact with the outer side of the first baffle 11 and the second baffle 12, clamping the first baffle 11 and the second baffle 12, so that the free ends of the first baffle 11 and the second baffle 12 always maintain a tendency to close.

[0050] Optionally, the pressing member 21 includes a transition section 211, and the transition section 211 can abut against the first baffle 11 and the second baffle 12 at the same time, so that the free ends of the first baffle 11 and the second baffle 12 are opened, thereby exposing the window 100. In this embodiment, the transition section 211 is a conical surface structure. When the pressing member 21 is pressed downward, the diameter of the conical surface structure in contact with the first baffle 11 and the second baffle 12 gradually increases, which facilitates the conversion of the linear motion of the pressing member 21 into the rotational motion of the first baffle 11 and the second baffle 12. In other embodiments, the transition section 211 can also be an arc surface structure, as long as the change in the cross section can drive the first baffle 11 and the second baffle 12 to open.

[0051] To facilitate the pressing member 21 to apply force to the first baffle 11 and the second baffle 12, optionally, the first baffle 11 and the second baffle 12 are both provided with a notch 13, and the transition section 211 is passed through the notch 13 of the first baffle 11 and the second baffle 12, and can squeeze the first baffle 11 and the second baffle 12 so that the free ends of the first baffle 11 and the second baffle 12 are opened, thereby exposing the window 100.

Figure 3 As shown, in this embodiment, the base 3 is provided with a receiving groove 34, and a guide groove 35 is opened at the bottom of the receiving groove 34. The cross-sectional area of ​​the guide groove 35 is smaller than the cross-sectional area of ​​the receiving groove 34, and the small diameter section 213 movably passes through the receiving groove 34 and the guide groove 35 and extends out of the base 3.

[0053] Optionally, a stop structure 214 is provided at one end of the small diameter section 213 close to the transition section 211, and the elastic member 22 is sandwiched between the stop structure 214 and the base 3. The elastic member 22 is disposed in the receiving groove 34, and the elastic member 22 can be a spring, which is sleeved on the small diameter section 213, and one end of the spring abuts against the stop structure 214, and the other end abuts against the bottom of the receiving groove 34.

[0054] To prevent the pressing member 21 from being separated from the base 3, optionally, a limiting member 215 is provided at one end of the small diameter section 213 extending outside the base 3, and the limiting member 215 can be in contact with the base 3. A clamping groove 216 is provided on the small diameter section 213, and the limiting member 215 can be a buckle-like structure and clamped in the clamping groove 216.

[0055] The window dust prevention device provided in this embodiment is used when the finger presses the top of the large diameter section 212 of the pressing member 21, the pressing member 21 moves downward, the elastic member 22 is compressed, the transition section 211 abuts against the first baffle 11 and the second baffle 12, and because the transition section 211 is a conical surface, the contact circle diameter of the transition section 211 and the first baffle 11 and the second baffle 12 becomes larger and larger, and the free ends of the first baffle 11 and the second baffle 12 open to expose the window 100 for the laser to pass through. After use, the finger is separated from the pressing member 21, and the pressing member 21 moves upward under the elastic force of the elastic member 22, and the contact circle diameter of the transition section 211 and the first baffle 11 and the second baffle 12 becomes smaller and smaller, and the free ends of the first baffle 11 and the second baffle 12 are closed to block the window 100, and the window 100 is automatically closed, and there is no need to pay special attention to whether the window 100 is closed, which effectively prevents dust and other debris from falling into the laser device.

[0056] This embodiment also provides a laser device, including the above-mentioned window dust-proof device, which can protect the window 100 from dust. No extra actions are required, and the optical fiber connector can be normally plugged in and out. It has a simple structure, few operating steps, and low operating difficulty.
