Description

Technical Field

[0001] This utility model relates to the field of beauty instrument technology, and more specifically, it relates to a photoelectric beauty instrument with an easy-to-replace head. Background Technology

[0002] In existing technologies, if the installation and fixation of the guide head relies on threads or clips, after repeated use, the fixing parts may wear down due to frequent twisting or impact, resulting in an unreliable installation position of the guide head, which is prone to loosening. During operation, the photoelectric beauty device may generate a certain amount of vibration, especially at high power output. This vibration will exacerbate the loosening of the guide head, affect the beauty effect, and may even lead to safety accidents.

[0003] First, some photoelectric beauty devices require users to rotate or press the buckle forcefully to install or remove the head. This is not only time-consuming and laborious, but improper operation can easily damage the parts and affect the long-term use of the device. When the head needs to be replaced, the traditional locking method may make the disassembly process cumbersome for users. In particular, if the head has not been disassembled for a long time, the parts may rust or get stuck due to dust accumulation, making disassembly even more difficult.

[0004] Secondly, if each guide head replacement requires a long time to disassemble and install, especially for users who need to frequently replace guide heads, this will greatly increase the time cost of operation and reduce work efficiency. Frequent installation and disassembly may cause damage to the guide head interface, especially threaded connections and clips, which are prone to wear due to improper operation or overuse, ultimately leading to equipment failure.

The spring block 16 is installed at one end of the sliding rod 15. The support spring 17 is installed between the spring block 16 and the outer wall of the locking tube 6. The support spring 17 pushes the spring block 16 into the mating hole 14, and the rotating block 13 presses against the spring block 16, causing the sliding rod 15 and the support spring 17 to retract.

[0033] In this embodiment, the rotating tube 12 is located on the outer wall of the clamping tube 6, which can limit the rotation and ensure the stability of the mechanism. The rotating clamp 9 is installed at the top of the rotating tube 12 and cooperates with the quick clamping mechanism to lock or release the guide head. The rotating block 13 is installed at the bottom of the rotating tube 12 and can rotate to control the clamping state. The mating hole 14 is located on the rotating block 13 and is used to cooperate with the sliding rod 15 to provide a limiting function. Multiple sets of sliding rods 15 are located on the outer wall of the clamping tube 6 and provide elastic restoring force through the spring block 16 and the support spring 17. When installing the guide head, the rotating block 13 presses against the spring block 16, causing the sliding rod 15 and the support spring 17 to retract and release the limiting. When the rotating tube 12 rotates to the appropriate position, the support spring 17 restores its elasticity, causing the sliding rod 15 to be repositioned, further enhancing the clamping stability.

[0034] Please see Figures 1-5 As a supplementary embodiment of the photoelectric beauty instrument that facilitates the replacement of the guide head, with a stable installation mechanism, a quick-connect mechanism, and a connecting auxiliary mechanism: A supply line 18 is installed inside the control handle 1, and one end of the supply line 18 extends out of the control handle 1 to connect with an external device. Placement racks 19 are installed at both ends of the control handle 1, and the control handle 1 is placed on the external device through the placement racks 19. A supply tube 20 is installed at one end of the mating plate 3, and one end of the supply line 18 extends into the supply tube 20 and is electrically connected to the guide head body 5. A guide hole 21 is opened on the outer wall of the connecting tube 6, and the sliding rod 15 is slidably guided in the guide hole 21. A connecting plate 22 is installed at the bottom end of the side wall of the connecting tube 6, and the connecting plate 22 is fixedly installed on the bottom end face of the mating plate 3. One end of the connecting rod 7 is connected to the mounting plate 4, and the other end of the connecting rod 7 extends through the mating plate 3 to quickly connect with the connecting tube 6.

[0035] More specifically, align the plug assembly 2 with the mating plate 3, ensuring the guide head is correctly placed in the mounting area of ​​the control handle 1. Insert the locking rod 7 into the locking tube 6, aligning the locking slot 8 with the extension rod 11. Rotate the rotating clamp 9, pushing the receiving clamp 10 to insert the extension rod 11 into the locking slot 8, thus securing the guide head. The rotating block 13 resets, and the spring block 16 pushes the sliding rod 15, further securing the locking mechanism and ensuring the guide head will not loosen. Insert the supply line 18 into the supply tube 20, electrically connecting the guide head, making the beauty device ready. Inside the control handle 1... The supply line 18 transmits power through the supply pipe 20 to provide photoelectric function to the guide head. The beauty instrument operates according to the set program. The guide head outputs photoelectric signals to perform beauty care. The stable installation mechanism and the locking mechanism ensure that the guide head will not loosen. Even if the device is moved during the beauty process, it can remain stable. The rotating clamp 9 operates in the reverse direction, so that the clamping plate 10 moves away from the extension rod 11, releasing the locking state. The rotating block 13 presses against the spring block 16, so that the sliding rod 15 retracts, releasing the limit. Then, a new guide head is replaced, and the installation steps are repeated.

[0036] In summary, during the use or operation of the entire device: when a stable installation mechanism is required, ensure that the guide head can be firmly installed on the control handle 1 and stably connected to the internal power supply and signal lines to ensure the normal use of the photoelectric beauty device. The plug assembly 2 is installed on the side of the guide head body 5, and its function is to electrically connect with the supply line 18 inside the control handle 1 to realize the transmission of electrical energy or signals. The mounting plate 4 is located on the side of the plug assembly 2 as a fixing component for connecting the guide head. The mating plate 3 is used to cooperate with the mounting plate 4 to ensure that the guide head can be stably fixed on the beauty device. During installation, the plug assembly 2 will fit against the mating plate 3, and the quick-clamping mechanism will achieve a tight connection between the mounting plate 4 and the mating plate 3, so that the guide head is firmly in place.

[0037] When the quick-connect mechanism is needed, it enables rapid installation and removal of the guide head, avoiding complex screw fixing methods and improving replacement efficiency. The connecting rod 7 is connected to the mounting plate 4 at one end, and the other end passes through the mating plate 3 and mates with the connecting tube 6 to form a basic connecting structure. The slot 8 is located on the side wall of the connecting rod 7 to lock the guide head. The extension rod 11 is slidably installed on the side wall of the connecting tube 6, and its function is to control the locking and releasing of the connecting rod 7. The receiving plate 10 is installed at one end of the extension rod 11 and can be slidably connected to the rotating clamp 9. When the guide head is inserted into the beauty device and aligned with the connecting position, the rotating clamp 9 will push the receiving plate 10, so that the extension rod 11 extends into the slot 8, thereby completing the connection and fixing the guide head. If the guide head needs to be replaced, rotate the rotating clamp 9 to move the receiving plate 10 away from the extension rod 11, thereby allowing the extension rod 11 to exit the slot 8 and releasing the guide head.

[0038] When the locking auxiliary mechanism is required to operate, the rotating tube 12 is located on the outer wall of the locking tube 6, which can limit the rotation and ensure the stability of the mechanism. The rotating clamp 9 is installed at the top of the rotating tube 12 and cooperates with the quick locking mechanism to lock or release the guide head. The rotating block 13 is installed at the bottom of the rotating tube 12 and can rotate to control the locking state. The mating hole 14 is located on the rotating block 13 and is used to cooperate with the sliding rod 15 to provide a limiting function. Multiple sets of sliding rods 15 are located on the outer wall of the locking tube 6 and provide elastic restoring force through the spring block 16 and the support spring 17. When installing the guide head, the rotating block 13 presses against the spring block 16, causing the sliding rod 15 and the support spring 17 to retract and release the limiting. When the rotating tube 12 rotates to the appropriate position, the support spring 17 restores its elasticity, causing the sliding rod 15 to be repositioned, further enhancing the locking stability.

[0039] Align the plug assembly 2 with the mating plate 3, ensuring the guide head is correctly placed in the mounting area of ​​the control handle 1. Insert the locking rod 7 into the locking tube 6 and align the locking slot 8 with the extension rod 11. Rotate the rotating clamp 9 and push the receiving clamp 10, causing the extension rod 11 to insert into the locking slot 8, thus securing the guide head. The rotating block 13 resets, and the spring block 16 pushes the sliding rod 15, further securing the locking mechanism and ensuring the guide head will not loosen. Insert the supply line 18 into the supply tube 20, electrically connecting the guide head, making the beauty device ready. The supply inside the control handle 1... Line 18 transmits power through supply pipe 20 to provide photoelectric function to the guide head. The beauty device operates according to the set program. The guide head outputs photoelectric signals to perform beauty care. The stable installation mechanism and locking mechanism ensure that the guide head will not loosen. Even if the device is moved during the beauty process, it can remain stable. Rotating the rotating clamp 9 reverses the operation, so that the clamping plate 10 moves away from the extension rod 11, releasing the locking state. The rotating block 13 presses against the spring block 16, causing the sliding rod 15 to retract, releasing the limit, and replacing the new guide head. The installation steps are repeated.
