Description

Technical Field

[0001] This utility model belongs to the field of medical aesthetic equipment, specifically relating to a negative pressure multi-stage radio frequency handpiece. Background Technology

[0002] In recent years, radiofrequency skin tightening and wrinkle removal has become increasingly popular in home and medical aesthetic industries. During facial skin tightening and wrinkle removal using medical aesthetic instruments, each instrument is equipped with a matching handpiece for direct application to the face. The working principle is as follows: radiofrequency generates heat in the handpiece (i.e., warming). When the handpiece is applied to the skin, it produces heat, which stimulates fibroblasts to produce more collagen deep within the skin. This collagen production improves skin tissue cells, achieving the goal of skin tightening and wrinkle removal. However, existing radiofrequency handpieces suffer from limited functionality, poor treatment effectiveness, and a less than ideal user experience. Furthermore, the disassembly, replacement, and installation of the treatment head are cumbersome. Therefore, to address these issues, it is essential to develop a negative pressure multi-stage radiofrequency handpiece that is easy to install and operate while offering superior treatment results. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a negative pressure multi-stage radiofrequency handpiece that is easy to install and operate and has good therapeutic effects.

[0004] The purpose of this utility model is achieved as follows: A negative pressure multi-stage radiofrequency handpiece includes a handpiece body, a tail locking mechanism, a decorative ring, and a treatment head. The handpiece body includes a left handpiece shell and a right handpiece shell. The left and right handpiece shells have the same structure and are symmetrically arranged. The left and right handpiece shells are connected by snap-fit ​​and fixed with bolts to achieve limiting between them. An inner liner ring is fitted at the tail end between the left and right handpiece shells, a control button is fitted at the upper end between them, and a main control button is located inside the lower end between them. The device comprises a plate and a hand tool core. A pressure sensor is mounted on the main control board. The hand tool core includes an inner body, quick-twist elbow a, and quick-twist elbow b. The inner body is annular, with an infrared lens concentrically mounted at its lower end and an infrared lamp plate concentrically mounted at its upper end. A heat sink is fixedly connected above the infrared lamp plate. A sealing element is fitted around the infrared lens. Quick-twist elbow a and quick-twist elbow b are both fixedly mounted on the upper end of the inner body. Quick-twist elbow a is connected to the pressure sensor on the main control board, and quick-twist elbow b is connected to the main unit's air circuit. The tail lock... A threaded rotating sleeve is fitted onto the tail of the handpiece body; a decorative ring is threaded rotatingly fitted onto the lower part of the handpiece body, and an arc-shaped guide positioning protrusion is fixedly provided on the upper surface of the decorative ring. Upper clamping components are fixedly installed on both sides of the lower end. The upper clamping component includes a mounting base a and a clamping block a fixedly installed below the mounting base a, with a ball-head plunger vertically inserted into the lower end of the clamping block a; the treatment head is located directly below the decorative ring, and includes a bottom shell, an electrode, and a lower clamping component. A through hole is provided at the center of the upper surface of the bottom shell, and the outer surface of the upper shell is concentrically placed... The device has an annular lamp plate with a treatment cavity in the center of its lower surface. Multiple electrodes are evenly distributed on the outer surface of the lower surface of the base shell. The electrodes, lamp plate, and base shell are connected by vertical screws. Two lower locking components are located on either side of the upper end of the lamp plate. Each component includes a mounting base b and a locking block b fixed above the mounting base b. The locking block b is rotatably locked to the locking block a. The mounting base b is connected to the base shell by bolts, and the upper surface of the mounting base b has a calibration hole that mates with the lower end structure of the ball-head plunger.

[0005] Furthermore, the main body of the hand tool also includes a decorative cover, which is fixedly fastened to the rear end between the left shell and the right shell of the hand tool, and the decorative cover is made of silicone material.

[0006] Furthermore, a positioning ring is fixedly provided on the upper surface of the bottom shell. The positioning ring is concentrically arranged with the through hole and located between the through hole and the lamp plate. The outer diameter of the positioning ring matches the inner diameter of the decorative ring.

[0007] Furthermore, an oil storage groove is formed by a downward recess between the positioning ring and the through hole.

[0008] Furthermore, multiple LED beads are evenly arranged on the lamp panel.

[0009] The beneficial effects of this utility model are as follows: By setting a tail locking and decorative ring, and utilizing the threaded connection between the tail locking, decorative ring and the main body of the handpiece, the connection stability between the left and right shells of the handpiece can be increased, while also improving the overall aesthetics of the utility model. By setting an upper and lower locking piece, and utilizing the rotational locking of the upper and lower locking pieces, the treatment head can be positioned and installed below the main body of the handpiece. The ball plunger can be used to perform position calibration by cooperating with the lower end of the ball plunger and the calibration hole, thereby judging whether the upper and lower locking pieces are rotated and locked in place. At the same time, the lower locking piece can also be used to transmit radiofrequency energy to the electrodes, thereby performing radiofrequency treatment on the patient's skin that is adsorbed into the treatment cavity by negative pressure suction through the cooperation of multiple electrodes under the bottom shell. By incorporating quick-tightening elbows a and b, a main control board, and a pressure sensor, the connection between quick-tightening elbow a and the pressure sensor facilitates the detection of pressure within the negative pressure chamber. This prevents excessive negative pressure from causing pain due to excessive absorption of the treatment chamber into the skin, thus improving user comfort. Furthermore, the inclusion of an infrared lens, an infrared lamp board, and a heat sink allows for infrared-assisted treatment of the patient's skin. The heat sink dissipates heat from the infrared lamp board, preventing damage from overheating. The lamp board's LEDs facilitate the assessment of its operational status. Overall, this invention offers advantages such as convenient installation and operation, and excellent therapeutic effects. Attached Figure Description
