Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical aesthetic devices, specifically relating to a negative pressure radio frequency handpiece. Background Technology
[0002] In recent years, radiofrequency skin tightening and wrinkle removal has been widely used 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 user's skin, it produces heat to the skin tissue. This heat, deep within the skin, stimulates fibroblasts to produce more collagen, thereby improving skin tissue cells and achieving the goal of skin tightening and wrinkle removal. However, existing radiofrequency handpieces have relatively limited functionality and offer poor treatment results and a less than ideal user experience. Therefore, to address these issues, it is essential to develop a multifunctional negative pressure radiofrequency handpiece with superior treatment effects. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a negative pressure radiofrequency handpiece with diverse functions and good therapeutic effects.
[0004] The purpose of this utility model is achieved as follows: A negative pressure 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, which have the same structure and are symmetrically arranged. The left and right handpiece shells are connected by a snap-fit and fixed with bolts to achieve a limiting relationship between them. An inner liner ring is fitted at the tail end between the left and right handpiece shells. A screen assembly and control buttons are sequentially arranged at the upper end between them. An infrared temperature probe is vertically inserted into the front end of the space through a fixing sleeve. A main control board and a handpiece core are arranged inside the lower end of the space. A pressure sensor is installed on the main control board. The handpiece core includes an inner body, a quick-turning bend a, a quick-turning bend b, and a spring pin. The inner body is annular, with an infrared lens concentrically arranged at its lower end and an infrared lamp plate concentrically arranged at its upper end. The upper part of the infrared lamp plate is fixed. The device includes a heat dissipation component. Quick-twist elbows a and b are fixedly mounted on the upper end of the inner body. Elbow a is connected to a pressure sensor on the main control board, and elbow b is connected to the main unit's air circuit. Multiple spring pins are vertically threaded and rotate through the outer end of the lower surface of the inner body. A tail-locking thread is rotatably fitted onto the tail of the handle body. A decorative ring is threaded and rotatedly fitted below the handle body, with magnets a fixedly embedded at each of the four corners of its lower surface. The treatment head is located directly below the decorative ring and includes a bottom shell and an identification plate. Magnets b are fixedly embedded at each of the four corners of the upper surface of the bottom shell. A through hole is located in the middle of the upper surface, and a treatment cavity is located in the middle of the lower surface. The treatment cavity communicates with the through hole, and electrodes are fixedly mounted on both sides inside the treatment cavity. A drainage notch is located at the upper end of the through hole. The identification plate is fixedly mounted inside the bottom shell.
[0005] Furthermore, an annular positioning protrusion is fixedly provided in the middle of the upper surface of the bottom shell. The positioning protrusion is concentrically arranged with the through hole, and its outer diameter matches the inner diameter of the decorative ring.

By setting magnets a and b, the mutual magnetic attraction between magnets a and b increases the convenience of installation and removal of the treatment head under the handle body. The infrared temperature probe allows for real-time temperature measurement of the treatment area during use. The quick-turning bend a, quick-turning bend b, main control board, and pressure sensor, with the connection between quick-turning bend a and the pressure sensor, facilitate the detection of pressure in the negative pressure chamber formed inside the utility model, thereby preventing excessive negative pressure. This invention addresses the problem of excessive suction and pain caused by large head size, improving user comfort. By incorporating an infrared lens, infrared lamp plate, and heat sink, the infrared lamp plate and lens work together to provide infrared-assisted treatment to the patient's skin, while the heat sink prevents damage due to overheating. An identification plate allows for the reading and recording of treatment head information and usage counts via a mobile terminal. A spring needle and electrodes are also included; the spring needle transmits radiofrequency energy to the electrodes, and the two electrodes work together to provide radiofrequency treatment to the patient's skin, which is suctioned into the treatment cavity by negative pressure. Overall, this invention offers the advantages of diverse functions and excellent therapeutic effects. Attached Figure Description

Finally, the treatment head 4 is positioned directly below the decorative ring 3 by the magnetic attraction between magnet a31 and magnet b43, thus completing the overall installation of the present invention.
[0018] In use, this invention utilizes the magnetic attraction between magnets a31 and b43 to increase the ease of installation and removal of the treatment head 4 under the handle body 1. The infrared temperature probe 7 allows for real-time temperature measurement of the treatment area. The infrared lamp plate 96 and infrared lens 95 work together to provide infrared-assisted treatment to the patient's skin. The heat sink 97 dissipates heat from the infrared lamp plate 96, preventing damage due to overheating. The spring needle 94 transmits radio frequency energy to the electrode 45, and the two electrodes 45 work together to attract the treatment head through negative pressure. Radiofrequency treatment is performed on the patient's skin inside the treatment cavity. Using the identification plate 42, information about the treatment head 4 and the number of uses can be read and recorded via a mobile terminal. Utilizing the quick-twist bend a92, quick-twist bend b93, and pressure sensor, the pressure in the negative pressure cavity formed inside the device can be detected through the connection between the quick-twist bend a92 and the pressure sensor. This avoids excessive negative pressure that could cause pain due to excessive absorption of the treatment cavity into the user's skin, thus improving the comfort of using the device. In summary, this device has the advantages of diverse functions and good therapeutic effects.
