Description

Technical Field

[0001] This utility model belongs to the field of laser therapy device technology, and specifically relates to a handheld component for a laser therapy device. Background Technology

[0002] A laser therapy device is a treatment instrument that utilizes the photothermal and photochemical effects of lasers to act on human tissues. Laser therapy devices are typically based on the principles of selective absorption and thermal effects of light. The laser instrument emits light waves of specific wavelengths that can penetrate the skin's surface and be absorbed by target chromophores such as melanin and hemoglobin within the skin. The handheld component of the laser therapy device is a key part; a well-designed handheld component can improve user convenience and comfort while reducing the risk of the device being dropped.

[0003] Announcement No. "CN221358228U" discloses a handheld laser therapy device, including a laser therapy head. A mounting shell is mounted on the front of the laser therapy head. The mounting shell has symmetrically formed mounting grooves on its front, and symmetrically formed sliding grooves at the top and bottom of each mounting groove. Positioning and rolling components are symmetrically mounted inside the mounting grooves via the sliding grooves. These positioning and rolling components ensure the distance between the laser therapy head and the skin being treated. The positioning and rolling components include a connecting plate, with sliders symmetrically mounted at the top and bottom of the connecting plate, and the sliders engaging with the sliding grooves. A roller is rotatably mounted on the inner side of the connecting plate. This invention has the following advantages and effects: When the laser therapy device moves, the roller also rotates relative to it, ensuring a constant distance between the laser source and the skin, resulting in the same treatment effect for each area of ​​skin and avoiding differences in treatment effects due to varying distances.

[0004] Although the rollers of the aforementioned utility model rotate relative to the laser therapy device when it is moved, ensuring a constant distance between the laser source and the skin and making the treatment effect on each area of ​​skin the same, thus avoiding different treatment effects due to different distances, the laser window glass needs to withstand high temperatures and high-intensity laser radiation during operation. After prolonged use, it may become damaged or age. The aged glass may develop microcracks, bubbles, or impurities, causing the laser beam to scatter, refract, or absorb during transmission, thereby reducing the intensity and focusing performance of the laser beam. Furthermore, its light transmittance, heat resistance, and other properties will decrease, thus affecting the transmission efficiency of the laser beam and the stability of the laser. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a handheld component for a laser therapy device to solve the problem that the laser window glass needs to withstand high temperature and high intensity laser radiation during operation, and will be damaged or aged after long-term use. The aged glass will produce micro-cracks, bubbles or impurities inside, causing the laser beam to scatter, refract or absorb during transmission, thereby reducing the intensity and focusing performance of the laser beam.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A handheld component for a laser therapy device includes a laser therapy head, a connecting wire fixedly connected to the bottom of the laser therapy head, a mounting shell movably connected to the top of the laser therapy head, a laser window opened at the upper end of the mounting shell, a laser glass fixedly connected inside the laser window, and assembly blocks symmetrically fixedly connected to the bottom end of the mounting shell, with fixing components installed inside the assembly blocks.

[0008] The fixing assembly includes a cavity, a first return spring, a movable plate, and a locking block. The cavity is located inside the assembly block. The first return spring is fixedly connected to one side of the cavity, and the movable plate is fixedly connected to the other end of the first return spring. The movable plate is slidably connected to the cavity. A locking block is fixedly connected to the side of the movable plate away from the first return spring. The locking block extends out of the assembly block from the side away from the movable plate, and its bottom end has a bevel. The upper end of the laser treatment head has symmetrically arranged assembly grooves that insert into the assembly block. A locking groove is located on one side of each assembly groove. The locking block is snapped into place. Both sides of the laser treatment head have through holes that connect to the inside of the locking groove. A push post is slidably connected inside the through hole. A push handle is fixedly connected to the other end of the push post. A second return spring is fixedly connected to one side of the push handle. The other end of the second return spring is fixedly connected to the laser treatment head. The second return spring is sleeved on the outside of the push post. This ensures that the laser treatment device is always in the best working condition and prevents the aging of the glass inside the laser window from causing a decrease in its light transmittance, heat resistance, and mechanical strength. This maintains the high precision and high efficiency of the laser treatment device.

[0009] As a preferred technical solution, the push handle is symmetrically fixedly connected to the limit post on the side near the push post, and the laser treatment head is symmetrically opened on both sides. The limit post and the limit hole are slidably connected. The cooperation between the limit post and the limit hole restricts the movement range of the push post, thereby ensuring the accuracy and repeatability of the action.

[0010] As a preferred technical solution, positioning posts are symmetrically fixedly connected to the top of the laser treatment head near the chamfer, and positioning holes are symmetrically opened at the bottom of the mounting shell near the chamfer. The positioning posts and positioning holes are plugged in, which ensures that the mounting shell and the laser head can be accurately positioned during installation, helps to avoid deviations during the installation process, and ensures that the laser beam can be accurately transmitted through the laser glass, thereby improving the overall performance of the laser equipment.

[0011] As a preferred technical solution, anti-slip pads are glued to both sides of the laser treatment head. The surface of the anti-slip pads has anti-slip textures, and the anti-slip pads are made of soft rubber. This can significantly increase the grip stability of the laser treatment head during use, increase the friction between the hand and the laser treatment head, and prevent the risk of slipping due to sweaty hands or a smooth surface of the laser treatment head.

[0012] As a preferred technical solution, a display screen is installed on one side of the laser treatment head, and control buttons are symmetrically installed on the side of the laser treatment head near the display screen. The display screen can display information such as the working status, parameter settings, and treatment effects of the laser therapy device in real time. The control buttons allow users to directly set and adjust parameters on the laser head, such as output energy, pulse width, and treatment time.

[0013] In summary, the present invention has the following main advantages:

[0014] In this invention, the mounting shell is combined with one end of the laser treatment head, and the assembly block is inserted into the assembly slot. During insertion, the squeezing force applies pressure to the inclined surface of one end of the locking block, causing the locking block to drive the moving plate to press against the first return spring. The first return spring is compressed, and the locking block retracts into the cavity. When the locking block moves to the locking slot, the first return spring resets, and the locking block pops out and engages with the locking slot to fix it in place. This completes the installation of the mounting shell and the laser glass, ensuring that the laser therapy device always maintains its optimal working condition and preventing the aging of the glass inside the laser window from causing a decrease in its light transmittance, heat resistance, and mechanical strength, thus maintaining the high precision and high efficiency of the laser therapy device.

[0021] Example

[0022] refer to Figures 1 to 5 The handheld component of the laser therapy device described in this embodiment includes a laser therapy head 1, a connecting line 4 fixedly connected to the bottom of the laser therapy head 1, a mounting shell 5 movably connected to the top of the laser therapy head 1, a laser window 6 opened at the upper end of the mounting shell 5, a laser glass 7 fixedly connected inside the laser window 6, and assembly blocks 8 symmetrically fixedly connected to the bottom end of the mounting shell 5, with a fixing component 10 installed inside the assembly block 8.

[0023] The fixing assembly 10 includes a cavity 101, a first return spring 102, a moving plate 103, and a locking block 104. The cavity 101 is formed inside the assembly block 8. The first return spring 102 is fixedly connected to one side of the cavity 101, and the moving plate 103 is fixedly connected to the other end of the first return spring 102. The moving plate 103 is slidably connected to the cavity 101. The locking block 104 is fixedly connected to the side of the moving plate 103 away from the first return spring 102. The locking block 104 extends out of the assembly block 8 from the end away from the moving plate 103. The bottom end of the locking block 104 has a bevel. The upper end of the laser treatment head 1 has symmetrically formed assembly grooves 9, which are inserted into the assembly block 8. A locking groove 11 is provided on one side of the assembly groove 9. The locking groove 11 and the locking block 104 are snapped together. The mounting shell 5 is merged with one end of the laser treatment head 1, so that the assembly block 8 is inserted into the assembly groove 9. During the insertion process, the squeezing force applies pressure to the inclined surface of one end of the locking block 104, so that the locking block 104 drives the moving plate 103 to press against the first return spring 102. The first return spring 102 is compressed, and at the same time the locking block 104 retracts into the cavity 101. When the locking block 104 moves to the locking groove 11, the first return spring 102 is reset, and the locking block 104 pops out and snaps into the locking groove 11 to fix it, thus completing the installation of the mounting shell 5 and the laser glass 7.

[0024] refer to Figure 4 and Figure 5Both sides of the laser treatment head 1 have through holes 12, which are connected to the inside of the locking groove 11. A push post 14 is slidably connected inside the through hole 12. A push handle 13 is fixedly connected to the other end of the push post 14. A second return spring 15 is fixedly connected to one side of the push handle 13. The other end of the second return spring 15 is fixedly connected to the laser treatment head 1. The second return spring 15 is sleeved on the outside of the push post 14. Pushing the push handle 13 causes the push post 14 to slide inside the through hole. At the same time, the second return spring 15 is compressed. The push post 14 pushes the locking block 104, causing the locking block 104 to drive the moving plate 103 to press against the first return spring 102. The first return spring 102 is compressed. At the same time, the locking block 104 retracts into the cavity 101. The locking block 104 and the locking groove 11 are no longer engaged. The mounting shell 5 is pulled outward, causing the assembly block 8 and the assembly groove 9 to be no longer inserted. The mounting shell 5 and the laser glass 7 are disassembled.

[0025] refer to Figure 4 The push handle 13 is symmetrically fixedly connected to the limiting post 16 on the side near the push post 14. The laser treatment head 1 has symmetrical limiting holes 17 on both sides. The limiting post 16 and the limiting hole 17 are slidably connected. When the push handle 13 pushes the push post 14 to move, the push handle 13 drives the limiting post 16 to slide inside the limiting hole.

[0026] refer to Figure 2 and Figure 3 The laser treatment head 1 is symmetrically fixed with positioning posts 18 near the chamfer at the top. The mounting shell 5 is symmetrically provided with positioning holes 19 near the chamfer at the bottom. The positioning posts 18 and the positioning holes 19 are plugged in. The mounting shell 5 and one end of the laser treatment head 1 are merged together so that the positioning posts 18 are inserted into the positioning holes 19.

[0027] refer to Figure 1 Both sides of the laser treatment head 1 are glued with anti-slip pads 20. The surface of the anti-slip pads 20 is provided with anti-slip texture. The anti-slip pads 20 are made of soft rubber. The anti-slip pads 20 can significantly increase the grip stability of the laser treatment head 1 during use, increase the friction between the hand and the laser treatment head 1, and prevent the risk of slipping due to sweaty hands or a smooth surface of the laser treatment head 1.

[0028] refer to Figure 1 A display screen 2 is installed on one side of the laser treatment head 1, and control buttons 3 are symmetrically installed on the side of the laser treatment head 1 near the display screen 2. The display screen 2 can display information such as the working status, parameter settings and treatment effect of the laser treatment device in real time. The control buttons 3 allow users to directly set and adjust parameters on the laser head, such as output energy, pulse width and treatment time.

[0029] Operating principle and advantages: First, the mounting shell 5 is joined to one end of the laser treatment head 1, and the assembly block 8 is inserted into the assembly groove 9. During insertion, the squeezing force applies pressure to the inclined surface of one end of the locking block 104, causing the locking block 104 to drive the moving plate 103 to press against the first return spring 102. The first return spring 102 is compressed, and at the same time, the locking block 104 retracts into the cavity 101. When the locking block 104 moves to the locking groove 11, the first return spring 102 returns to its original position, and the locking block 104 pops out and engages with the locking groove 11 for fixation, thus completing the mounting shell 5 and the laser treatment head 1. When the laser glass 7 ages, push the push handle 13. The push handle 13 drives the push column 14 to slide inside the through hole. At the same time, the second return spring 15 is compressed. The push column 14 pushes the locking block 104, so that the locking block 104 drives the moving plate 103 to press against the first return spring 102. The first return spring 102 is compressed. At the same time, the locking block 104 retracts into the cavity 101. The locking block 104 and the locking groove 11 are no longer engaged. Pull the mounting shell 5 outward so that the assembly block 8 and the assembly groove 9 are no longer engaged. The mounting shell 5 and the laser glass 7 are disassembled.

[0030] This invention ensures that the laser therapy device is always in optimal working condition, preventing the aging of the glass inside the laser window from causing a decline in its light transmittance, heat resistance, and mechanical strength, thus maintaining the high precision and efficiency of the laser therapy device.
