DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] Aiming at the problem in the prior art that the wrinkle removal effect is limited and the effect duration is short due to the limited energy penetration depth and low output power, the embodiment of the present invention provides a monopolar ice radio frequency beauty instrument, which is a home radio frequency beauty instrument. Figure 1 This is one of the structural diagrams of the monopolar ice radio frequency beauty instrument provided by the embodiment of the present invention. Figure 1 As shown, the monopolar ice radio frequency beauty device includes: a treatment head 100 and a body 200.

[0026] The body 200 includes a main control feedback loop 210, an RF power amplification module 220 and an RF negative electrode 230, wherein: the main control feedback loop 210 is used to generate a control signal and a DC signal, the control signal is used to control whether the RF power amplification module 220 is working; the RF power amplification module 220 is used to convert the DC signal into an RF signal when the control signal is valid.

[0027] The treatment head 100 includes a radio frequency positive electrode 110, which is located in a different plane from the radio frequency negative electrode 230; the radio frequency positive electrode 110 is used to apply the radio frequency signal to the target layer of the skin, and the target layer includes at least the deep layer of the dermis.

[0028] Specifically, a control signal and a DC signal are generated by the main control feedback loop 210 provided in the body 200 of the monopolar ice RF beauty device. The level of the control signal is used to control whether the RF power amplifier module 220 is in operation. For example, when the control signal is a high-level signal, the RF power amplifier module 220 is controlled to be in an operating state, that is, the RF power amplifier module 220 is controlled to convert the DC signal into an RF signal. When the control signal is a low-level signal, the RF power amplifier module 220 is controlled to be in an inoperative state. At this time, no RF signal is generated, that is, the monopolar ice RF beauty device does not heat the skin. The control signal is generated under the premise of ensuring that all modules in the monopolar ice RF beauty device are in a safe state. The DC signal is a signal after adjusting the output voltage and output current, and is used to control the stability of the RF power in the RF power amplifier module 220.

[0029] In the prior art, in bipolar RF beauty devices and multipolar RF beauty devices, the positive electrode and the negative electrode are located in the same plane as the treatment area of ​​the skin, and the RF circuit is located between the positive electrode and the negative electrode. The maximum theoretical penetration depth of this RF circuit is half of the distance between the positive electrode and the negative electrode, that is, the maximum energy penetration depth is 1mm to 3mm, which can only heat the superficial layer of the dermis and cannot penetrate into the deep layer of the dermis, resulting in limited wrinkle removal effect. Therefore, in the embodiment of the present invention, Figure 2 This is the second structural diagram of the monopolar ice radio frequency beauty instrument provided by the embodiment of the present invention, such as Figure 2 As shown, the RF negative electrode 230 is arranged on both sides of the lower middle part of the body 200 (i.e., the hand-held position of the monopolar ice RF beauty instrument), while the RF positive electrode 110 is arranged on the side of the treatment head 100 away from the body 200. The RF positive electrode 110 and the RF negative electrode 230 are not in the same plane, that is, the RF positive electrode 110 and the RF negative electrode 230 do not contact the skin at the same time, and only the RF positive electrode 110 is in direct contact with the skin. When the RF negative electrode 230 on the body 200 is held by the hand and the RF positive electrode 110 contacts the skin, a monopolar RF circuit is formed. Compared with the RF circuit in the prior art, the monopolar RF circuit in the embodiment of the present invention is extended, which increases the penetration depth of the RF energy, enables the RF signal to act on the target layer for heating, and improves the wrinkle removal effect.

[0030] It should be noted that the radio frequency signal in the embodiment of the present invention can penetrate up to 4.3 mm and heat the target layer, including the epidermis, superficial dermis, deep dermis, and fascia.

[0031] Furthermore, the output power range of bipolar and multipolar RF beauty devices in the prior art is 5W-10W, which is relatively low. However, the effectiveness of RF wrinkle reduction is directly related to the output power: the greater the output power, the higher the temperature of the dermis. Within a safe range, the higher the temperature, the more significant the collagen proliferation effect, i.e., the more pronounced the wrinkle reduction effect and the longer it lasts. Therefore, in the embodiment of the present invention, the output power of the RF power amplifier module 220 can reach a maximum of 25W. The output power in the embodiment of the present invention is higher than that in the prior art, resulting in a longer-lasting wrinkle reduction effect and immediate improvement.

[0032] The monopolar ice radio frequency beauty instrument provided by the embodiment of the present invention generates a control signal and a DC signal through the main control feedback loop 210. When the control signal controls the radio frequency power amplifier module 220 to be in a working state, the radio frequency power amplifier module 220 converts the DC signal into a radio frequency signal. The radio frequency positive electrode 110 and the radio frequency negative electrode 230 are in different planes, and the radio frequency positive electrode 110 and the radio frequency negative electrode 230 do not contact the skin at the same time, forming an extended monopolar radio frequency loop. After the radio frequency positive electrode 110 contacts the skin, the extended monopolar radio frequency loop increases the penetration depth of the radio frequency signal, so that the radio frequency signal acts on the target layer of the skin, heats the temperature of the target layer, improves the wrinkle removal effect, and the effect lasts longer.

[0033] Furthermore, the monopolar ice radio frequency beauty instrument also includes a refrigeration component 240, which includes a cold compress end 120 and a heat dissipation end. The cold compress end 120 is arranged on the treatment head 100 and is used to cool the skin and the radio frequency positive electrode 110, and the heat dissipation end is arranged on the body 200.

[0034] In the existing technology, there is no home radio frequency beauty device that can cool the electrodes and skin at the same time. Only the Thermage in the clinic has the function of cooling the electrodes. Figure 3 It is a schematic diagram of heating and cooling provided by the prior art, such as Figure 3 As shown, the RF heating area (red) is located outside the cooling area (blue). During RF output, the accumulated RF energy increases the skin temperature, causing a burning sensation and poor comfort. This is particularly true for those with heat-sensitive skin or those with heat intolerance. RF beauty devices with cooling functions cannot simultaneously operate the RF heating and cooling functions. Therefore, they cannot simultaneously cool the heated skin in the treatment area while RF energy is being delivered. Cooling the skin after the RF treatment can only be achieved by applying an ice compress, which does not alleviate the burning sensation during treatment.

[0035] Therefore, in this embodiment of the present invention, a refrigeration assembly 240 (thermoelectric cooler, TEC) is also provided. This refrigeration assembly 240 includes a cooling end 120 and a heat dissipation end. The heat dissipation end is disposed within the body 200, and the cooling end 120 is disposed within the treatment head 100. This refrigeration assembly 240 utilizes ice radio frequency technology to simultaneously cool the radio frequency positive electrode 110 and the skin surface based on monopolar radio frequency. Figure 4 is a cross-sectional schematic diagram of a treatment head 100 provided in an embodiment of the present invention, as shown in FIG. Figure 4 As shown, the cold compress end 120 is disposed on the outside of the RF positive electrode 110 . Figure 5 Schematic diagram of monopolar radio frequency heating and cooling provided by an embodiment of the present invention, such as Figure 5 As shown, the RF heating area (i.e., the red area in the center) is distributed in the center, and the cooling area (i.e., the blue area outside the red area) is distributed outside the RF heating area. During the treatment, the monopolar ice RF beauty instrument is held and slid by hand to cover the skin in the heated area with the cold compress end 120, thereby cooling the skin in the heated area. At the same time, in order to prevent the skin from experiencing large temperature changes in a short period of time, people with sensitive skin are particularly susceptible to temperature differences, which can lead to skin redness, allergies and other problems. In an embodiment of the present invention, the cold compress end 120 is also provided on the back of the RF positive electrode 110, and the cooling area (i.e., the blue area in the center) also overlaps with the RF heating area (i.e., the red area in the center). While the RF positive electrode 110 is working, the back of the RF positive electrode 110 is cooled, and the skin in the area directly heated by the RF positive electrode 110 is moderately cooled. After the two are combined, the skin can be cooled by sliding the monopolar ice RF beauty instrument in the hand during the treatment. At the same time, the temperature of the target layer is higher than the epidermal temperature, ensuring the wrinkle removal effect while alleviating the burning sensation of the RF electrode, improving the user's comfort, and solving the temperature intolerance problem of people with sensitive skin.

[0036] It should be noted that this monopolar ice RF beauty device has two modes: performance mode and ice RF mode. In performance mode, only RF power output is provided, that is, only RF heating is performed. In ice RF mode, the RF electrode and skin are cooled while RF heating is performed.

[0037] Furthermore, the main control feedback loop 210 includes a main control module 211, a power module 212 and a current detection module 213, wherein: The current detection module 213 is connected to the power module 212 and the main control module 211, and the main control module 211 is also connected to the power module 212 and the RF power amplification module 220; The current detection module 213 is used to determine the current detection signal corresponding to the power module 212; The main control module 211 is used to generate a power regulation signal based on the current detection signal; and is also used to generate the control signal; the power regulation signal is used to adjust the output voltage and output current of the power module 212; The power module 212 generates a DC signal based on the power regulation signal; The current detection module 213 is configured to send the DC signal to the RF power amplification module 220 .

[0038] Specifically, Figure 6 This is the third structural diagram of the monopolar ice radio frequency beauty instrument provided by the embodiment of the present invention, as shown in FIG. Figure 6 As shown, after the power module 212 outputs power, the current detection module 213 detects the output current of the power module 212 to obtain a current detection signal, and sends the current detection signal to the main control module 211. The main control module 211 determines whether the output current of the power module 212 is greater than the current threshold through the current detection signal. If it is greater, a power adjustment signal is generated and sent to the power module 212 to control the power module 212 to adjust the output voltage and output current to ensure the stability of the subsequent RF power and obtain a DC signal. When a DC signal is obtained, or when the output current of the power module 212 is less than or equal to the current threshold, a control signal is generated, and the RF power amplification module 220 is controlled to be in an operating state through the control signal, so that the RF power amplification module 220 converts the DC signal into an RF signal.

[0039] It should be noted that the frequency range of the radio frequency signal may be 300 KHz to 300 MHz, and the frequency of the radio frequency signal is preferably 6.78 MHz, which is not limited in the embodiment of the present invention.

[0040] Furthermore, if Figure 6 As shown, the body 200 further includes an impedance adaptive module 250, and the impedance adaptive module 250 is connected to the RF power amplification module 220, the RF positive electrode 110 and the RF negative electrode 230; The impedance adaptive module 250 is used to adjust the RF output voltage of the RF signal based on the RF input transient current and the human body impedance corresponding to the skin when the RF positive electrode 110 contacts the skin; The radio frequency positive electrode 110 is used to apply the adjusted radio frequency signal to the target layer of the skin.

[0041] Specifically, the human body is a conductor. Due to factors such as individual differences in skin anatomical structure (e.g., the thickness and condition of the stratum corneum, epidermis, and dermis), real-time changes in skin physiological status (e.g., hydration, sebum, and sweat), and individual physiological characteristics (e.g., age, gender, and health), the impedance of different bodies varies. If the RF signal's RF output voltage is fixed, the RF power output for different bodies will vary, resulting in different wrinkle-reducing effects. Therefore, in this embodiment of the present invention, when the treatment head 100 contacts the skin of different bodies (i.e., when different bodies with different impedances are connected), the impedance adaptive module 250 detects the RF input transient current and adjusts the RF output voltage based on this RF input transient current, ensuring relative consistency in the RF power output for different bodies. This allows the monopolar ice RF beauty device to achieve comparable beauty effects for different bodies, ensuring consistent wrinkle-reducing effects.

[0042] Furthermore, if Figure 6 As shown, the fuselage 200 further includes an empty load detection module 260 , and the empty load detection module 260 is connected to the main control module 211 ; The no-load detection module 260 is used to determine a no-load detection result based on the RF current and a preset current range. The no-load detection result is used to indicate whether the RF current is within the preset current range, so as to determine whether the RF positive electrode 110 reaches an effective contact area with the skin.

[0043] Specifically, when the RF positive electrode 110 is in contact with the skin, the RF current can be detected by the no-load detection module 260, and the RF current can be compared with the preset current range to obtain a no-load detection result. If the RF current is within the preset current range, it indicates that the RF positive electrode 110 and the skin have reached an effective contact area. At this time, the main control module 211 can generate a control signal as a high-level signal to control the RF power amplifier module 220 to work normally. If the RF current is outside the preset current range, it indicates that the RF positive electrode 110 and the skin have not reached an effective contact area. At this time, the main control module 211 can generate a control signal as a low-level signal to control the RF power amplifier module 220 to suspend output.

[0044] Furthermore, the main control module 211 is further configured to: determine a duration corresponding to a target state if the no-load detection result indicates that the RF current is outside the preset current; and generate a shutdown command if the duration is greater than or equal to the preset duration. The target state indicates that the RF positive electrode 110 has not reached an effective contact area with the skin. This shutdown command can cause the monopolar ice RF beauty device to automatically shut down.

[0045] Furthermore, if Figure 6As shown, the body 200 further includes a displacement monitoring module 270 , and the displacement monitoring module 270 is connected to the main control module 211 ; The displacement monitoring module 270 is used to detect acceleration and determine a displacement monitoring result, and the displacement monitoring result is used to indicate whether the monopolar ice radio frequency beauty device is moving.

[0046] Specifically, the displacement monitoring module 270 can be a three-axis acceleration sensor. The displacement monitoring module 270 can detect the acceleration of the monopolar ice RF beauty device and compare the acceleration with a third preset threshold. If the acceleration is greater than the third preset threshold, indicating that the monopolar ice RF beauty device is in motion, the main control module 211 can generate a high-level control signal to control the normal operation of the RF power amplifier module 220. If the acceleration is less than or equal to the third preset threshold, indicating that the monopolar ice RF beauty device is stationary, the main control module 211 can generate a low-level control signal to control the RF power amplifier module 220 to suspend output until the monopolar ice RF beauty device is detected to be in motion, at which point the RF power amplifier module 220 can resume normal operation.

[0047] Further, if Figure 6 As shown, the body 200 further includes a temperature control module 280 , and the temperature control module 280 is connected to the main control module 211 ; The temperature control module 280 is used to collect skin temperature and body 200 temperature; The main control module 211 is used to generate a radio frequency output adjustment signal and a cooling adjustment signal based on the skin temperature and the body temperature, and feed the radio frequency output adjustment signal and the cooling adjustment signal back to the temperature control module 280 .

[0048] Specifically, in an embodiment of the present invention, the skin temperature and the body 200 temperature can be collected by the temperature control module 280. If the skin temperature is greater than a first preset threshold value and / or the body 200 temperature is greater than a second preset threshold value, indicating that the current temperature is too high, the main control module 211 can generate an RF output adjustment signal and a cooling adjustment signal and feed them back to the temperature control module 280. The temperature control module 280 can control the RF power amplification module 220 to suspend output via the RF output adjustment signal and / or control the cooling component 240 to increase cooling power via the cooling adjustment signal. If the skin temperature is less than or equal to the first preset threshold value and the body 200 temperature is less than or equal to the second preset threshold value, the main control module 211 can generate an RF output adjustment signal and a cooling adjustment signal and feed them back to the temperature control module 280. The temperature control module 280 can control the RF power amplification module 220 to operate normally via the RF output adjustment signal and / or control the cooling component 240 to operate normally via the cooling adjustment signal.

[0049] Furthermore, the main control module 211 is used to generate a control signal corresponding to the RF power amplification module 220 and / or a control signal corresponding to the refrigeration component 240 based on the no-load detection result, the displacement monitoring result, the skin temperature and the temperature of the body 200.

[0050] Furthermore, the body 200 further includes an alarm module 290 , and the alarm module 290 is connected to the main control module 211 ; The alarm module 290 is used to generate an alarm when a preset condition is met; The preset conditions include at least one of the following: The no-load detection result is that the radio frequency current is outside the preset current range; The displacement monitoring result shows that the monopolar ice radio frequency beauty device has not moved; The skin temperature is greater than a first preset threshold; The temperature of the body 200 is greater than a second preset threshold.

[0051] Specifically, the alarm device may include a buzzer, a vibrator, and an indicator light, etc., which is not limited in the embodiment of the present invention. If the no-load detection result, the displacement monitoring result, the skin temperature, and the temperature of the body 200 do not meet the preset conditions, it indicates that the monopolar ice radio frequency beauty device is currently in a safe state. At this time, the main control module 211 can generate a control signal as a high-level signal to control the radio frequency power amplifier module 220 to operate normally, and can control the indicator light in the alarm device to be in a constant light state to indicate normal operation. If at least one of the no-load detection result, the displacement monitoring result, the skin temperature, and the temperature of the body 200 meets the preset conditions, it indicates that the monopolar ice radio frequency beauty device is currently in an unsafe state. At this time, the main control module 211 can generate a control signal as a low-level signal to control the radio frequency power amplifier module 220 to suspend output. At the same time, the buzzer can be controlled to ring, the vibrator can vibrate, the indicator light can be turned off or flashing, and other prompting methods can be controlled to remind the user of abnormal operation.

[0052] In addition, if Figure 6 As shown, the body 200 further includes a Bluetooth module 300 , through which the Bluetooth module 300 can be connected to an App (Application) on the terminal for data transmission and interaction.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
