Description

Technical Field

[0001] This application relates to the field of skin beauty devices, and in particular to a connecting structure for a beauty device handpiece. Background Technology

[0002] Beauty devices are machines used to regulate and improve the skin texture of the body and face. They can be categorized by function (e.g., whitening, skin rejuvenation, blemish removal, wrinkle reduction) and by operating principle (e.g., ultrasonic, radiofrequency skin tightening). Modern beauty devices are diverse, easy to use, and users can purchase and assemble them themselves.

[0003] The related beauty device includes a handpiece and a contact point. The handpiece is made of a plastic shell, and the beauty element is installed inside the plastic shell. The contact point is fixedly connected to the handpiece and is used to contact the user's skin. The beauty element can emit radio frequency waves, which are conducted to the skin through the contact point to achieve the beauty effect.

[0004] The aforementioned technical solutions have the following drawbacks: the size and shape of the connector are fixed, making it difficult to adapt to the cosmetic needs of different locations such as the face and neck, causing inconvenience. Utility Model Content

[0005] In order to enable the abutment to be detachably connected to the handpiece, this application provides a connection structure for a beauty instrument handpiece.

[0006] The connecting structure for a beauty instrument handpiece provided in this application adopts the following technical solution:

[0007] A connecting structure for a beauty device handpiece includes a handpiece, an abutment, and a locking mechanism. The locking mechanism is disposed in the handpiece. The abutment includes a disc and a connecting rod. The disc is connected to the connecting rod. The connecting rod is inserted into the locking mechanism and connected to the beauty element inside the handpiece. A slot is provided on the outer wall of the connecting rod, and the locking mechanism locks into the connecting rod through the slot.

[0008] By adopting the above technical solution, a locking mechanism is set on the handpiece, allowing the connecting rod to be inserted into the locking mechanism and enter the handpiece. The beauty element inside the handpiece can contact the connecting rod, thereby allowing heat, current, or mechanical vibration to be conducted to the disc through the connecting rod. The user holds the handpiece and presses the disc against the skin, achieving a beauty massage effect. By controlling the action of the locking mechanism, the user can lock the locking mechanism into the slot of the connecting rod or disengage it, thus making the connecting rod detachably connected to the locking mechanism. The user can change the abutment of different shapes according to different massage positions.

[0009] Optionally, the snap-fit ​​mechanism includes an outer tube, an inner tube, a spring, and multiple steel balls. The inner tube passes through and is fixed to the housing of the hand tool. The outer tube is sleeved and slidably connected to the inner tube. The spring is sleeved on the inner tube, with one end connected to the inner tube and the other end connected to the outer tube. Multiple mounting holes are equidistantly spaced along the circumference of the inner tube. Each steel ball is set in one mounting hole. The steel ball is used to protrude from the mounting hole and be snapped into the slot. A clearance groove is provided on the inner wall of the outer tube. When the outer tube slides to the position of the clearance groove corresponding to the mounting hole, the steel ball is movably connected between the outer tube and the inner tube.

[0010] By adopting the above technical solution, the inner tube is fixedly connected in the handpiece, and the outer tube is slidably connected to the inner tube. The user can slide the outer tube, causing it to compress the spring, thereby causing the clearance groove on the outer tube to slide to the position corresponding to the steel ball. At this time, the steel ball can slide between the inner tube and the outer tube. When the user pulls out the connecting rod, the steel ball automatically retracts into the outer side of the inner tube, allowing the connecting rod to disengage from the inner tube. When using the beauty device, the spring supports the outer tube, ensuring that the outer tube always supports the steel ball. When the connecting rod is subjected to force, the steel ball bears the stress and maintains a stable position.

[0011] Optionally, the diameter of the mounting hole is smaller than the diameter of the steel ball.

[0012] By adopting the above technical solution, and by placing the steel ball on the outside of the mounting hole, it is difficult for the steel ball to enter the inner tube from the outside and fall off. During the replacement of the connector, the steel ball is always stably installed between the outer tube and the inner tube.

[0013] Optionally, a snap-fit ​​protrusion is provided on the inner wall of the outer tube, and a snap-fit ​​ring is provided on the outer wall of the end of the inner tube, and the snap-fit ​​ring snaps with the snap-fit ​​protrusion.

[0014] By adopting the above technical solution, a snap-fit ​​protrusion is set on the inner wall of the outer tube, so that the snap-fit ​​protrusion and the snap-fit ​​ring abut against each other, thereby keeping the outer tube and the inner tube connected at all times and reducing the chance of the outer tube slipping off the inner tube.

[0015] Optionally, the snap ring can be detachably connected to the inner tube.

[0016] By adopting the above technical solution, the snap ring can be made of rubber material, allowing the user to remove the snap ring from the inner tube and slide the outer tube out of the inner tube, which facilitates the user's maintenance and replacement of the spring and steel ball.

[0017] Optionally, the length direction of the hand tool is perpendicular to the length direction of the clamping mechanism.

[0018] By adopting the above technical solution, when the user holds the device with one hand, they can slide the outer tube with the other hand, making it easier to hold the device and press the disc against their skin.

[0019] Optionally, the connecting rod has a threaded end and a threaded hole at the center of the disc, and the connecting rod is detachably connected to the disc by the thread.

[0020] By adopting the above technical solution, and by creating threads on the connecting rod, the connecting rod and the disc can be detachably connected. This allows users to install discs of different shapes on the connecting rod for massage, making it convenient to use and saving production costs.

[0021] Optionally, the abutment is made of a material with good thermal conductivity.

[0022] By adopting the above technical solution, when a heating resistance wire is installed inside the handpiece, the contact point can be heated through the heating resistance wire, thereby reducing discomfort when the disc touches the skin and improving the user experience.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By setting a snap-fit ​​mechanism on the handpiece, the connecting rod can be inserted into the snap-fit ​​mechanism and enter the handpiece. The beauty element inside the handpiece can contact the connecting rod, so that heat, current or mechanical vibration can be conducted to the disc through the connecting rod. The user holds the handpiece and presses the disc against the skin, which can achieve the effect of beauty massage. The user can control the action of the snap-fit ​​mechanism to make the snap-fit ​​mechanism snap into the slot of the connecting rod or disengage it, so that the connecting rod can be detachably connected to the snap-fit ​​mechanism. The user can change the abutment of different shapes according to different massage positions.

[0025] 2. By fixing the inner tube in the handpiece, the outer tube is slidably connected to the inner tube. The user can slide the outer tube, causing it to compress the spring. This causes the clearance groove on the outer tube to slide to the position corresponding to the steel ball. At this time, the steel ball can slide between the inner and outer tubes. When the user pulls out the connecting rod, the steel ball automatically retracts into the outer side of the inner tube, allowing the connecting rod to disengage from the inner tube. When using the beauty device, the spring supports the outer tube, ensuring that the outer tube always supports the steel ball. When the connecting rod is subjected to force, the steel ball bears the stress and maintains a stable position.

[0026] 3. By creating threads on the connecting rod, the connecting rod and the disc can be detachably connected, making it convenient for users to install discs of different shapes on the connecting rod for massage, which is convenient to use and saves production costs.

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] This application discloses a connecting structure for a beauty instrument handpiece, referring to... Figure 1 and Figure 2 The device includes a handpiece 1, an abutment 2, and a locking mechanism 3. The locking mechanism 3 is disposed within the handpiece 1, and the abutment 2 is detachably connected to the locking mechanism 3. A beauty element is disposed within the handpiece 1. When the abutment 2 is mounted on the locking mechanism 3, the abutment 2 connects to the beauty element within the handpiece 1. One end of the abutment 2 abuts against the beauty element, and the other end abuts against the user's skin, thereby transmitting mechanical vibration, heat energy, or electrical energy to stimulate and massage the skin. Depending on the function of the beauty device, different beauty elements with different functions can be installed within the handpiece 1. For example, a radiofrequency therapy device can be used. The radiofrequency therapy device emits radio waves, which are transmitted through the abutment 2 to the user's subcutaneous tissue, causing the natural resistance of the subcutaneous tissue to generate heat energy, thereby stimulating the skin and improving skin laxity. In other embodiments, an ultrasonic beauty device can be disposed within the handpiece 1. The ultrasonic beauty device generates ultrasonic waves, which are transmitted to the user's skin through the abutment 2, providing a skin care effect.

[0036] Reference Figure 3 and Figure 4The abutment 2 is made of a metal material with good electrical conductivity. Depending on the function of the beauty device, a material with good thermal conductivity or good elasticity can be selected to make the abutment 2, thereby improving the user's comfort. The abutment 2 includes a disc 21 and a connecting rod 22. The disc 21 is made of a smooth metal material, and the connecting rod 22 is perpendicular to the disc 21 and is installed at the center of one side of the disc 21. The connecting rod 22 is used to insert into the snap-fit ​​mechanism 3 and abut against the beauty element. The connecting rod 22 conducts electrical signals to the disc 21, which is used to abut against the user's skin. A threaded hole is opened at the center of the disc 21, and a threaded end 221 is opened at one end of the connecting rod 22. The threaded end 221 is threadedly connected to the disc 21. Users can install discs 21 or abutment parts of different shapes and sizes on the connecting rod 22, thereby facilitating the user to massage different areas of the skin with the abutment 2.

[0037] Reference Figure 5 and Figure 6 The end of the abutment 2 away from the threaded end 221 has a groove 222 for detachable connection with the locking mechanism 3. The locking mechanism 3 includes an outer tube 31, an inner tube 32, a spring 33, and multiple steel balls 34. The inner tube 32 is fixed to the hand tool 1 and inserted into the housing of the hand tool 1. The outer tube 31 is sleeved on the inner tube 32 and slidably connected to the inner tube 32. The spring 33 is sleeved on the inner tube 32, with one end fixed to the inner tube 32 and the other end fixed to the end of the outer tube 31. Multiple mounting holes 321 are equidistantly spaced along the circumferential direction on the inner tube 32, and a steel ball 34 is disposed in each mounting hole 321. The inner wall of the outer tube 31 has a clearance groove 311. In its natural state, the spring 33 pushes the outer tube 31, causing it to fit over the mounting hole 321. At this time, the inner wall of the outer tube 31 supports the steel ball 34, causing it to protrude from the mounting hole 321. When the connecting rod 22 is inserted into the inner tube 32, the steel ball 34 can be locked in the slot 222, thus fixing the connecting rod 22 to the inner tube 32. When the abutment 2 needs to be replaced, the user slides the outer tube 31 so that the clearance groove 311 inside the outer tube 31 corresponds to the mounting hole 321. At this time, the steel ball 34 can move within the clearance groove 311, allowing it to retract into the mounting hole 321. The connecting rod 22 can then be pulled out of the inner tube 32.

[0038] Reference Figure 5 The diameter of the mounting hole 321 is smaller than the diameter of the steel ball 34, and the steel ball 34 is positioned between the outer tube 31 and the inner tube 32. When the abutment 2 is not installed in the inner tube 32, the steel ball 34 is stuck between the inner tube 32 and the outer tube 31.

[0039] Reference Figure 5 and Figure 6A snap-fit ​​ring 322 is provided at the end of the inner tube 32 that extends outside the hand tool 1. An installation groove is provided on the outer wall of the inner tube 32, and the snap-fit ​​ring 322 is fitted into the installation groove. A snap-fit ​​protrusion ring 312 is provided on the inner wall of the outer tube 31, and the snap-fit ​​protrusion ring 312 is used to abut against the snap-fit ​​ring 322. In its natural state, spring 33 contracts and abuts against outer tube 31, ensuring that the snap-fit ​​protrusion 312 in outer tube 31 always abuts against one side of snap-fit ​​ring 322, thus maintaining the connection between outer tube 31 and inner tube 32. At this time, outer tube 31 supports steel ball 34, allowing steel ball 34 to extend from mounting hole 321 in inner tube 32. When the user needs to install or remove abutment 2, the user slides outer tube 31, causing outer tube 31 to compress spring 33. At this time, the clearance groove 311 in outer tube 31 can align with mounting hole 321, allowing steel ball 34 to move between outer tube 31 and inner tube 32. The user can then insert or remove connecting rod 22 into inner tube 32. After removing snap-fit ​​ring 322 from inner tube 32, the user can slide outer tube 31 out of inner tube 32, facilitating the user to disassemble snap-fit ​​mechanism 3 and replace spring 33 or steel ball 34 and other parts.

[0040] The implementation principle of this application embodiment is as follows: by setting a snap-fit ​​mechanism 3 in the hand tool 1, abutment 2 can be detachably connected in the snap-fit ​​mechanism 3, so that users can install abutment 2 of different shapes and sizes on the hand tool 1 and perform beauty massage. By setting a steel ball 34 between the inner tube 32 and the outer tube 31, the steel ball 34 can extend out from the mounting hole 321 on the inner wall of the inner tube 32, so that the steel ball 34 can be snapped in the slot 222 of the connecting rod 22, thereby achieving the effect of fixing the connecting rod 22 in the inner tube 32.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
