[0026] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] The therapeutic apparatus of the present application is a device that uses ultrasound, radio frequency or laser technology for skin treatment. For example, an ultrasonic therapeutic apparatus is a device that uses ultrasound technology to treat the skin. The basic principle is to use the mechanical vibration and thermal effect of ultrasound to deeply stimulate and treat the skin. Through the vibration, micro-massage effect and thermal effect of ultrasound, as well as the way of sound wave guidance, a non-invasive skin treatment method is provided to promote blood circulation and help improve skin quality. The core technology of the therapeutic apparatus is the energy conversion efficiency of the ultrasonic transducer, that is, the ultrasonic transducer converts the pulse voltage energy into ultrasonic vibration energy. The radio frequency therapeutic apparatus is a device that uses high-frequency current for skin treatment. The basic principle is to use the thermal effect of high-frequency current to perform deep thermal stimulation treatment on the skin, and by heating the dermis, collagen fibers are regenerated, so that the skin regains elasticity. The ultrasonic energy and radio frequency energy of the therapeutic apparatus of the present application can be collectively referred to as high-frequency energy, and its energy frequency order of magnitude is MHz.

[0031] However, the existing technical defects are that when the therapeutic device is powered on, it is always in a non-standby state, and some components of the machine work for a long time in this state, such as the power supply. However, the power supply components have a life span, and long-term working state affects their life span and reliability, and thus affects the life reliability of the whole machine; in addition, the machine is in a non-standby state for a long time, and the power consumption continues to be consumed, which does not meet the requirements of energy saving and consumption reduction. Therefore, the existing machine is relatively clumsy and it is difficult to meet the requirements of machine life and low power consumption, and it is urgent to improve.

[0032] The utility model provides a therapeutic instrument control circuit.

[0033] See also Figure 1 In one embodiment of the utility model, the therapeutic device control circuit is applied to the therapeutic device, including:

[0034] The energy output circuit 300 is used for converting and outputting energy.

[0035] It should be noted that the therapeutic device can be an ultrasonic therapeutic device, a radio frequency therapeutic device, or a laser therapeutic device, and the energy output circuit 300 can be used to convert electrical energy into ultrasonic output, to convert electrical energy into radio frequency energy, or to convert electrical energy into laser energy output, which is not limited here. For example, when the therapeutic device is an ultrasonic therapeutic device, the energy output circuit 300 can first convert the input power supply into a corresponding power supply, then convert the power supply into a pulse drive power supply, and then drive the ultrasonic transducer 340 to generate and output corresponding ultrasonic energy in an optimal manner through output impedance matching.

[0036] The human body detection circuit 100 is used to detect human body information when the human body is close to the therapeutic apparatus in the environment, and output a corresponding human body detection signal.

[0037] It should be noted that the human body detection circuit 100 can use infrared, microwave, millimeter wave, ultrasound, ToF, radar ranging and other technologies, or a fusion of the above technologies such as infrared and microwave technology to achieve the sensing of mobile human body information.

[0038] In one embodiment, see Figure 3 The human body detection circuit 100 uses infrared technology to sense the information of a moving human body. The sensing environment of the human body detection circuit 100 is specifically a sensing area 3002. The human body detection circuit 100 includes an infrared sensor 3001. The sensing area 3002 represents a spatial area that can be sensed by infrared. The sensing area can sense a human body entering the area. That is to say, any human body entering the sensing area can trigger the infrared sensor 3001 to output a human body detection signal that a human body is approaching. The spatial size of the sensing area 3002 can be determined by the shape and focal length of the Fresnel lens of the infrared sensor 3001. The optical lens can be designed according to actual needs to meet the needs of spatial sensing and achieve precise control of proximity.

[0039] Please note that Figure 4 The infrared signal recognition mechanism of the infrared sensor 3001 is specifically that when the infrared signal exceeds the upper threshold voltage 4001 and the lower threshold voltage 4002, and the first time interval ΔT1 and the second time interval ΔT2 are greater than the preset time value T0, the trigger output is a human body detection signal corresponding to a human body approaching the therapeutic device, such as a human body detection signal outputted as a high level. Among them, the baseline voltage 4003 in the waveform diagram is the basic output voltage of the infrared sensor when there is no infrared information, and the upper threshold voltage 4001 and the lower threshold voltage 4002 are voltage values ​​preset according to the sensitivity of the infrared sensor, which are used to set the sensitivity of the infrared trigger.

[0040] A main control circuit 200, wherein a first signal input terminal of the main control circuit 200 is electrically connected to a signal output terminal of the human body detection circuit 100, and a first control terminal of the main control circuit 200 is electrically connected to a controlled terminal of the energy output circuit 300; the main control circuit 200 is used to control the energy output circuit 300 to enter a non-standby state when a human body is detected approaching the therapeutic apparatus according to a human body detection signal; and / or, when no human body is detected approaching the therapeutic apparatus according to a human body detection signal, control the energy output circuit 300 to stop working or enter a standby state.

[0041] In this embodiment, the energy output circuit 300 enters a non-standby state, specifically, the energy output circuit 300 enters a normal working state. In this state, the power supply and other components that maintain normal energy output work will continue to work, and the energy consumption is relatively high. In response to the energy output start instruction, the energy output circuit 300 can normally perform energy conversion and output. It should be noted that the standby state is specifically a low-power state. In this embodiment, when the energy output circuit 300 stops working or enters the standby state, the power supply and other components that maintain normal energy output work will stop working or work in a low-power state, and there is no need to respond to the energy output start instruction.

[0042] In this embodiment, the human body detection circuit 100 can detect human body information in the environment when approaching the therapeutic instrument. When the sensing area of ​​the human body detection circuit 100 detects human body information, that is, detects that a human body is approaching, a human body detection signal indicating that a human body is approaching is output; when the sensing area of ​​the human body detection circuit 100 does not detect human body information, that is, detects that no human body is approaching, a human body detection signal indicating that no human body is approaching is output. When the main control circuit 200 determines that a human body is approaching the therapeutic instrument according to the human body detection signal, it controls the energy output circuit 300 to enter a non-standby state, that is, to enter a normal working state. At this time, in response to the energy output start instruction, the energy output circuit 300 can normally perform energy conversion and output. And / or, when the main control circuit 200 determines that no human body is approaching the therapeutic instrument according to the human body detection signal, it controls the energy output circuit 300 to stop working or enter a standby state. In this way, this embodiment can solve the problem that the existing therapeutic instrument is in a non-standby state when there is no human body approaching the therapeutic instrument, and the power supply therein is still working, resulting in high energy consumption and shortened device life. Compared with the prior art, this embodiment can reduce the power consumption of the therapeutic apparatus and extend the life of components such as the power supply in the therapeutic apparatus, meeting modern energy-saving requirements.

[0043] In the present utility model, the human body detection circuit 100 can detect the human body information when approaching the therapeutic apparatus in the environment. When the sensing area of ​​the human body detection circuit 100 detects human body information, that is, detects that a human body is approaching, a human body detection signal indicating that a human body is approaching is output; when the sensing area of ​​the human body detection circuit 100 does not detect human body information, that is, detects that no human body is approaching, a human body detection signal indicating that no human body is approaching is output. When the main control circuit 200 determines that a human body is approaching the therapeutic apparatus according to the human body detection signal, it controls the energy output circuit 300 to enter a non-standby state, that is, to enter a normal working state. At this time, in response to the energy output start instruction, the energy output circuit 300 can normally perform energy conversion and output. And / or, when the main control circuit 200 determines that no human body is approaching the therapeutic apparatus according to the human body detection signal, it controls the energy output circuit 300 to stop working or enter a standby state. In this way, the present utility model can solve the problem that the existing therapeutic apparatus is in a non-standby state when there is no human body approaching the therapeutic apparatus, and the power supply therein is still working, resulting in high energy consumption and shortened device life. Compared with the prior art, the utility model can reduce the power consumption of the therapeutic apparatus and extend the life of components such as the power supply in the therapeutic apparatus, thus meeting modern energy-saving requirements.

[0044] It should be noted that the existing technical defect is that when the therapeutic device is connected to the power supply and is not in standby mode, the display screen is also in non-standby mode. The LED lights inside it will continue to consume electricity, which does not meet the requirements of energy saving and consumption reduction. In addition, the LED lights on the display screen will reduce their service life if they are turned on for a long time.

[0045] See also Figure 2 In one embodiment of the utility model, the therapeutic device control circuit further includes:

[0046] The display module 400 , wherein the controlled end of the display module 400 is electrically connected to the second control end of the main control circuit 200 .

[0047] The main control circuit 200 is used to control the display module 400 to enter a non-standby state when a human body is detected approaching the therapeutic device according to the human body detection signal; and / or, when no human body is detected approaching the therapeutic device according to the human body detection signal, control the display module 400 to stop working or enter a standby state.

[0048] It should be noted that the main control circuit 200 may include a display control circuit and a power control circuit. The display control circuit may provide human-computer interaction display control, internal and external communication control, and the reception and processing of human body detection signals and the determination of whether a human body is close to the therapeutic apparatus. The power control circuit may provide ultrasonic power control of the energy output circuit 300, communication control between the display control circuit and the energy output circuit 300, etc. In this embodiment, the display control circuit may directly control the display module 400 to enter a non-standby state, and / or stop working or enter a standby state according to the human body detection signal, and control the energy output circuit 300 to enter a non-standby state, and / or stop working or enter a standby state through the power control circuit.

[0049] It should be noted that the non-standby state of the display module 400 is specifically a normal display state, in which the LED lights therein emit light normally and consume high energy. On the contrary, the stop working or standby state of the display module 400 is specifically a black screen state or a dark screen state, in which the LED lights therein are off or emit light at a lower power.

[0050] It should be noted that the therapeutic instrument control circuit may also include a switching power supply circuit, the power output end of the switching power supply circuit is connected to the power input end of the main control circuit 200, and the switching power supply circuit is used to convert the external power supply voltage and then supply power to the main control circuit 200, the energy output circuit 300 and the human body detection circuit 100.

[0051] In this embodiment, the main control circuit 200 can control the display module 400 to enter a non-standby state when it is determined that a human body is close to the therapeutic apparatus according to the human body detection signal, and control the display module 400 to stop working or enter a standby state when it is determined that no human body is close to the therapeutic apparatus. In this way, this embodiment can reduce the power consumption of the display module 400 of the therapeutic apparatus and extend the service life of the LED lamp therein.

[0052] See also Figure 2 In one embodiment of the utility model, the therapeutic device control circuit further includes:

[0053] The communication switching circuit 500 is used for communication connection with the control terminal; the communication switching circuit 500 is also electrically connected to the signal interaction end of the main control circuit 200.

[0054] In this embodiment, the communication switching circuit 500 can be connected to the control terminal through the cloud server. It should be noted that the communication switching circuit 500 may include functions such as signal conversion, protocol matching, and interface expansion to achieve data interaction between the main control circuit 200 and the control terminal. Among them, the cloud server can provide information sharing and remote control, and the control terminal can provide remote control instructions, including sensor sensitivity settings, information collection and remote services.

[0055] In this embodiment, when the main control circuit 200 determines that there is no human body near the therapeutic apparatus, it can control the apparatus to enter a non-communication standby state and stop information exchange through the communication switching circuit 500. In this way, this embodiment can realize flexible control of the therapeutic apparatus by exchanging information with the control terminal.

[0056] See also Figure 2 and Figure 5 In one embodiment of the present utility model, the human body detection circuit 100 includes:

[0057] The proximity sensor circuit 110 is used to detect human body information when approaching the therapeutic device in the environment and output a corresponding human body detection signal.

[0058] The signal extraction circuit 120 has an input end electrically connected to an output end of the proximity sensor circuit 110 ; the signal extraction circuit 120 is used to extract a human body detection signal when a voltage value of the human body detection signal changes beyond a preset range.

[0059] The signal conditioning circuit 130 has an input end electrically connected to an output end of the signal extraction circuit 120, and an output end of the signal conditioning circuit 130 electrically connected to a first signal input end of the main control circuit 200. The signal conditioning circuit 130 is used for outputting a human body detection signal after signal conditioning; wherein the signal conditioning includes at least one of amplification, filtering, and biasing.

[0060] It should be noted that the proximity sensor circuit 110 may include a pyroelectric infrared sensor 111, which can detect infrared information of a human body when it is close to the therapeutic apparatus in the environment, and output a corresponding human body detection signal. Among them, the pyroelectric infrared sensor 111 can sense heat and generate an electrical signal. The pyroelectric infrared sensor 111 can sense human body information in the environment and output a small analog signal. The signal is extracted by the signal extraction circuit 120 through frequency selection, and the human body detection signal is extracted when the voltage value of the human body detection signal changes beyond a preset range. The signal is further amplified, filtered, and biased by the signal conditioning circuit 130, and then output to the main control circuit 200 for further analysis and processing to determine whether there is a human body close to the therapeutic apparatus. If a human body is close to the therapeutic apparatus, the energy output circuit 300 and other circuits are controlled to enter a non-standby state. If no human body is close to the therapeutic apparatus, the energy output circuit 300 and other circuits are controlled to stop working or enter a standby state. In this way, this embodiment can effectively filter environmental noise, enhance the ability to recognize human body signals, and improve the accuracy of the human body detection circuit 100 in practical applications.

[0061] See also Figure 2 and Figure 5In one embodiment of the present utility model, the therapeutic device control circuit further includes a display module 400, and the human body detection circuit 100 further includes:

[0062] A self-test circuit 140, wherein a first end of the self-test circuit 140 is electrically connected to a detection output end of the proximity sensor circuit 110, and a second end of the self-test circuit 140 is electrically connected to a detection input end of the main control circuit 200; the self-test circuit 140 is used to detect a working state of the proximity sensor circuit 110;

[0063] The main control circuit 200 is also used to control the display module 400 to display abnormal prompt information when the proximity sensor circuit 110 works abnormally.

[0064] In this embodiment, the main control circuit 200 can detect the voltage at the detection output end of the proximity sensor circuit 110 through the self-test circuit 140 and compare it with a preset voltage. When the voltage at the detection output end of the proximity sensor circuit 110 is outside the error range of the preset voltage, it is determined that the working state of the proximity sensor circuit 110 is abnormal, and the control display module 400 displays abnormal prompt information to notify the user to perform maintenance and other processing.

[0065] It should be noted that before the therapeutic apparatus works, the main control circuit 200 first completes self-test through the self-test circuit 140. When the user chooses to turn on the human body detection function, human body information detection is performed to sense whether there is anyone approaching the therapeutic apparatus in the environment. When someone approaches the therapeutic apparatus, the control enters the wake-up mode. In the wake-up mode, the energy output circuit 300 and the display module 400 both enter the non-standby state, and the display module 400 allows the user to enter user information or needs. The main control circuit 200 matches the corresponding treatment mode according to the user information (age, race, etc.) or needs, and controls the energy output circuit 300 to convert and output energy to start treatment according to the parameters of the corresponding treatment mode. If no one is close to the therapeutic apparatus, the control stops working or enters the standby state. In this way, this embodiment can reduce the power consumption of the therapeutic apparatus, and extend the service life of components such as the power supply in the energy output circuit 300 and the LED lamp of the display module 400.

[0066] See also Figure 6 In one embodiment of the utility model, the therapeutic apparatus includes a plurality of proximity detection areas, and a plurality of human body detection circuits 100 are provided, each of which is used to detect human body information when approaching the proximity detection area of ​​the therapeutic apparatus, and output a corresponding human body detection signal;

[0068] It should be noted that the therapeutic apparatus can be equipped with multiple proximity control points, that is, multiple human body detection circuits 100, to cover the sensing area. Among them, the main control circuit 200 can control the energy output circuit 300 to enter a non-standby state when a human body approaches any proximity detection area according to multiple human body detection signals. The human body detection circuit 100 can include but is not limited to being provided in a supporting position such as the main unit of the therapeutic apparatus, the column of the therapeutic apparatus, or the base of the therapeutic apparatus. In this way, the present embodiment can increase the sensing area, reduce the possibility of missed detection, and improve the detection effect.

[0073] The ultrasonic transducer 340 has an input end electrically connected to an output end of the matching control circuit 330; the ultrasonic transducer 340 is used to generate and output corresponding ultrasonic energy according to the electric energy provided by the pulse driving power supply; wherein the matching control circuit 330 is used to perform impedance matching according to the ultrasonic transducer 340 to maximize the output of the ultrasonic transducer 340.

[0074] In this embodiment, the main control circuit 200 outputs a power control signal to the power supply circuit 310, and the power supply circuit 310 converts the input power supply according to the power control signal, and outputs the corresponding power supply to the driving power supply circuit 320. The main control circuit 200 outputs a pulse control signal to the driving power supply circuit 320, and the driving power supply circuit 320 processes the power supply according to the pulse control signal and outputs the corresponding pulse driving power supply. It should be noted that when the high-frequency energy generator (such as an ultrasonic transducer, a radio frequency electrode, etc.) is working, the impedance of the input and output ends will affect the energy transmission efficiency. If the impedance does not match, it will cause energy reflection and loss, reducing the overall performance of the system. In this embodiment, the matching control circuit 330 can perform accurate impedance matching according to the characteristics of the ultrasonic transducer 340, and specifically can achieve the maximum energy output and minimize reflection of the ultrasonic transducer 340 by adjusting the parameters of the circuit (such as capacitors, inductors or other resistors). In this way, the ultrasonic transducer 340 can generate corresponding ultrasonic energy and maximize the output according to the electric energy provided by the pulse driving power supply under the optimal impedance matching network. In this way, this embodiment can realize the conversion of input power to ultrasonic energy output, and the efficiency of energy transmission and conversion is relatively high.

[0075] It should be noted that the high-frequency energy generator can also be a radio frequency electrode, which is used to generate high-frequency current according to the electric pulse provided by the pulse driving power supply, and the high-frequency current acts on the skin tissue layer structure.

[0085] In this embodiment, when the main control circuit 200 receives the identification signal, it also outputs a control sound driving circuit 640 to drive the speaker 620 to send a confirmation reception information to notify the user that the therapeutic device has successfully entered the instruction and will work according to the instruction. At the same time, the main control circuit 200 controls the energy output circuit 300 to work according to the corresponding instruction. Specifically, the main control circuit 200 outputs the corresponding power control signal and pulse control signal according to the instruction represented by the identification signal, that is, the voltage and pulse shape of the control power supply to control the high-frequency energy generator to generate the corresponding high-frequency energy and output it to achieve the corresponding treatment effect. In this way, the control operation of this embodiment is simple and easy to control different pulse power supplies according to the needs of users (age differences, cortical differences, etc.) to meet the nursing treatment needs of users and achieve a more ideal treatment effect.
