DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0029] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides a radio frequency beauty instrument handle, comprising: a working head 1 and a hand-held part 2. The working head 1 performs beauty treatment on the skin of the beauty user to achieve skin tightening and other effects. The hand-held part 2 is used by the worker to hold the radio frequency beauty instrument handle, and its design and shape are convenient for the worker to use. The hand-held part 2 is connected to the working head 1.

[0031] A positive electrode sheet 11 and a negative electrode sheet 12 are arranged in the working head 1. By arranging the positive electrode sheet 11 and the negative electrode sheet 12, the radio frequency energy acts on the skin between the positive electrode sheet 11 and the negative electrode sheet 12 to form a loop. A first temperature sensor 13 is arranged on the positive electrode sheet 11 for real-time acquisition of the temperature on the positive electrode sheet 11. A second temperature sensor 14 is arranged on the negative electrode sheet 12 for real-time acquisition of the temperature on the negative electrode sheet 12. An infrared temperature sensor 15 is arranged between the positive electrode sheet 11 and the negative electrode sheet 12 for acquisition of the skin temperature. During the working process, the heating area is mainly concentrated in the positive electrode sheet 11 and the negative electrode sheet 12 area, and the central area of ​​the positive electrode sheet 11 and the negative electrode sheet 12. Therefore, by arranging the first temperature sensor 13 on the positive electrode sheet 11, the second temperature sensor 14 on the negative electrode sheet 12, and the infrared temperature sensor 15 between the positive electrode sheet 11 and the negative electrode sheet 12, the temperature of the entire skin area sucked by the negative pressure is collected in real time, and it is judged in real time whether the temperature exceeds the preset threshold. If the temperature exceeds the preset threshold, the output of radio frequency energy will be cut off in time. Therefore, the temperature of the entire beauty area can be collected in real time, and the temperature change of any part of the skin will not be ignored, which improves the safety of work.

[0032] like Figure 2As shown, in some embodiments of the present invention, a support plate is provided between the positive electrode sheet 11 and the negative electrode sheet 12. The infrared temperature sensor 15 is provided in the middle of the support plate. The support plate facilitates the infrared temperature sensor 15 to be installed in the working head 1.

[0033] like Figure 3 As shown and combined with reference Figure 2 In some embodiments of the present invention, a control circuit 21 is provided in the handheld part 2. The control circuit 21 is used to control the first temperature sensor 13, the second temperature sensor 14 and the infrared temperature sensor 15, and to collect voltage and current data.

[0034] Since the current is not controlled by the head of the treatment handle on the market, if a large current fluctuation occurs, it often causes skin irritation on the surface of the treatment area, and a noticeable stinging sensation. Therefore, the control circuit 21 collects the voltage and current data of the working head 1 in real time, calculates the impedance curve, and monitors the impedance change in real time. If it exceeds the preset threshold, the current parameters are automatically adjusted to stabilize the impedance within a reasonable range.

[0035] like Figure 1 As shown and combined with reference Figure 3 In some embodiments of the present invention, a negative pressure gas circuit and a radio frequency circuit are also provided in the handheld part 2. The negative pressure gas circuit is used to form a negative pressure in the working head 1. The radio frequency circuit is used to output a radio frequency signal to the working head 1. Both the negative pressure gas circuit and the radio frequency circuit are connected to the control circuit 21.

[0036] like Figure 2 As shown, in some embodiments of the present invention, a suction hole 16 is provided in the working head 1. The suction hole 16 is connected to a negative pressure pump through a negative pressure air path.

[0037] like Figure 2 As shown, in some embodiments of the present invention, an arc plate 17 is further provided in the working head 1. A plurality of arc plates 17 are evenly and symmetrically distributed. When the negative pressure pump is started, after the skin to be beautified is subjected to negative pressure suction, the arc plate 17 is in direct contact with the skin to avoid clogging the suction hole 16.

[0038] like Figure 2 As shown, in some embodiments of the present invention, at least one positive electrode sheet 11 and at least one negative electrode sheet 12 are provided. That is, bipolar radio frequency or multipolar radio frequency can be used, and the specific production can be carried out according to the actual use needs.

[0039] like Figure 1As shown, in some embodiments of the present invention, the handheld portion 2 is connected to the working head 1 by snapping, magnetism or threading. The snapping, magnetism or threading method is simple and easy to install, and the installation method can be flexibly selected. It should be noted that other installation methods can also be used to install the handheld portion 2 and the working head 1 together, and the specific installation method is not limited.

[0040] like Figure 1 As shown, in some embodiments of the present invention, the front end of the working head 1 is open to form a cavity. When the negative pressure pump is started, a negative pressure environment is formed in the cavity, thereby performing negative pressure suction on the skin. After the skin is sucked, beauty treatment is performed.

[0041] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a radio frequency beauty instrument, including: a radio frequency beauty instrument handle and a host.

[0042] The host is provided with a main controller 3. The main controller 3 is connected to the handle of the radio frequency beauty instrument through a cable and an air path, and is used to control the control circuit 21 provided in the handheld part 2.

[0043] During the operation of the radio frequency beauty instrument handle, if the real-time collected temperature exceeds the preset threshold, a signal is sent to the main controller 3 in the host through the control circuit 21 in the handheld part 2, thereby cutting off the output of radio frequency energy in time.

[0044] like Figure 1-Figure 4As shown, when the radio frequency beauty instrument is working, the temperature is controlled: the main controller 3 sends a treatment signal to the control circuit 21, and the control circuit 21 controls the first temperature sensor 13, the second temperature sensor 14 and the infrared temperature sensor 15 to collect the temperature of the entire sucked skin area in real time. Specifically, the infrared temperature sensor 15 collects the temperature of the middle area of ​​the two electrode sheets through infrared radiation; the first temperature sensor 13 and the second temperature sensor 14 are respectively arranged in the positive electrode sheet 11 and the negative electrode sheet 12, and the temperature of the electrode sheet is measured by the thermal conductivity of the two electrode sheets, and then the temperature of the skin in contact with the electrode sheet is measured, so as to realize the temperature collection of the entire beauty area. It is judged whether the temperature reaches the lower limit of the preset threshold, and the lower limit temperature range is 32-36℃. If the lower limit temperature range of the preset threshold is not reached, the working head 1 starts to output radio frequency energy, and the radio frequency output can be performed according to the maximum radio frequency energy. In the process of outputting energy, the control circuit 21 controls the first temperature sensor 13, the second temperature sensor 14 and the infrared temperature sensor 15 to continuously collect the temperature in real time, and judge in real time whether the lower limit of the preset threshold is reached. If the lower temperature limit of the preset threshold is reached, an over-temperature signal will be sent to the control circuit 21. At this time, the output of the RF energy should be reduced to maintain the RF output. After the energy is reduced, the control circuit 21 controls the first temperature sensor 13, the second temperature sensor 14 and the infrared temperature sensor 15 to continue to collect the temperature in real time, and judge in real time whether the temperature reaches the upper limit of the preset threshold, and the upper temperature range is 42-46°C. If the upper temperature range of the preset threshold is not reached, the RF output is maintained according to the reduced RF energy; if the upper temperature range of the preset threshold is reached, the RF energy output is cut off and the treatment is ended. Avoid high temperature burns to the skin.

[0045] like Figure 1-Figure 3 as well as Figure 5 As shown, when the radio frequency beauty instrument is working, the control of impedance acquisition is: the main controller 3 sends a treatment signal to the control circuit 21 to perform radio frequency output, and the control circuit 21 automatically collects voltage, current and power data to determine whether the voltage, current and power values ​​exceed the corresponding thresholds. The upper limit of the voltage threshold is 460-510V, the upper limit of the current threshold is 3A-4A, and the upper limit of the power threshold is 70W-110W. If it does not exceed the corresponding threshold, maintain the current duty cycle to output radio frequency energy. If it exceeds the corresponding threshold, adjust the radio frequency duty cycle and reduce the voltage until the voltage, current and power values ​​are within the threshold range, so as to maintain the adjusted duty cycle for output. Avoid irritation of the skin area to be beautified due to excessive current.

[0046] In summary, the utility model arranges a first temperature sensor on the positive electrode sheet, a second temperature sensor on the negative electrode sheet, and an infrared temperature sensor between the positive electrode sheet and the negative electrode sheet, so that when the handle of the radio frequency beauty instrument is working, it can collect the temperature changes of the two heating areas in real time, so as to promptly discover the abnormal temperature rise of a certain beauty area and cut off the output of radio frequency energy in time, effectively avoiding the risk of scalding any area of ​​the beauty area and improving the safety of the operation of the handle of the radio frequency beauty instrument; at the same time, through the real-time collection of voltage and current by the control circuit, it can monitor in real time whether the impedance is within the set threshold, so as to avoid the working head causing irritation and discomfort to the skin of the beauty user after the impedance exceeds the threshold, thereby affecting the treatment experience.

[0047] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
