[0044] The present application will be further described in detail below with reference to the accompanying drawings.
[0045] This application provides a treatment head, treatment device, sound power adjustment method, and medium for stabilizing sound power.
[0046] A transducer in a treatment head converts electrical energy into ultrasonic energy, which is then used to treat human tissue. However, in existing methods, the acoustic power of the ultrasonic signals emitted by the treatment head is unstable, resulting in poor treatment efficacy and a risk of damaging human tissue. To address these issues, this application provides a treatment head, a treatment device, and a method for adjusting acoustic power. The treatment head is equipped with a pressure sensor connected to an outer surface membrane. When the transducer operates, the pressure of the acoustic medium on the outer surface membrane changes. The pressure sensor detects the pressure value and adjusts the acoustic power value accordingly to ensure stable acoustic power, improve treatment efficiency, and provide a better user experience.
[0047] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0048] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0049] A treatment head according to this application is described below. Please refer to... Figure 1 One embodiment of the treatment head of this application includes: a housing 1, an outer surface membrane 2, and a pressure sensor 3;
[0050] The housing 1 is provided with an ultrasonic wave penetration port. The outer surface membrane 2 is tightly attached to the ultrasonic wave penetration port to completely cover it. A transducer is disposed inside the housing 1. A sound-conducting medium is disposed in the space between the transducer and the ultrasonic wave penetration port inside the housing 1. The ultrasonic wave signal emitted by the transducer passes through the sound-conducting medium, the ultrasonic wave penetration port, and the outer surface membrane 2 to the outside of the housing 1. Specifically, the outer surface membrane 2 can seal the ultrasonic wave penetration port to prevent the sound-conducting medium from leaking out.
[0051] The pressure sensor 3 is connected to one side of the outer surface membrane 2 and is used to detect the pressure value of the sound guiding medium on the outer surface membrane 2 when the transducer is working, so as to stabilize the acoustic power value of the ultrasonic signal at a preset target acoustic power value based on the pressure value. Specifically, the pressure sensor 3 can be on either side of the outer surface membrane 2, as long as the pressure sensor 3 is connected to the outer surface membrane 2, and there is no specific limitation here.
[0052] The working principle of this embodiment will now be explained. When the transducer of the treatment head operates, the ultrasonic signal travels through the sound-conducting medium, the ultrasonic penetration port, and the outer surface membrane 2 to the outside of the housing 1. After absorbing energy, the sound-conducting medium enters a "boiling" state, causing a change in pressure on the outer surface membrane 2. The pressure sensor 3 sends the detected pressure value to a designated module to determine whether the sound power is too high or too low based on the pressure value. If it deviates from the target sound power value, adjustments are made to stabilize the sound power value at the target level.
[0053] In this embodiment, the treatment head is equipped with a pressure sensor 3, which is connected to the outer surface membrane 2. When the transducer in the treatment head is working, the sound-conducting medium absorbs energy and enters a "boiling" state. At this time, the pressure of the sound-conducting medium on the outer surface membrane 2 changes, causing the outer surface membrane 2 to deform under the force. Since the pressure sensor 3 is connected to the outer surface membrane 2, it detects the pressure value and can then adjust the sound power value based on the pressure value to stabilize the sound power value at the target sound power value. This ensures that the sound power does not fluctuate wildly, resulting in a more stable sound power, higher treatment efficiency, and a better user experience.
[0054] Please see Figure 2 and Figure 3 Another embodiment of a treatment head according to this application includes: a housing 1, an outer surface membrane 2, and a pressure sensor 3;
[0055] The housing 1 is provided with an ultrasonic wave penetration port. The outer surface membrane 2 is tightly attached to the ultrasonic wave penetration port to completely cover it. A transducer is disposed inside the housing 1. A sound-conducting medium is disposed in the space between the transducer and the ultrasonic wave penetration port inside the housing 1. The ultrasonic wave signal emitted by the transducer passes through the sound-conducting medium, the ultrasonic wave penetration port, and the outer surface membrane 2 to the outside of the housing 1. Specifically, the outer surface membrane 2 can seal the ultrasonic wave penetration port to prevent the sound-conducting medium from leaking out.
[0056] The pressure sensor 3 is connected to one side of the outer surface membrane 2 and is used to detect the pressure value of the sound guiding medium on the outer surface membrane 2 when the transducer is working, so as to stabilize the acoustic power value of the ultrasonic signal at a preset target acoustic power value according to the pressure value. Specifically, the pressure sensor 3 can be on either side of the outer surface membrane 2, as long as the pressure sensor 3 is connected to the outer surface membrane 2. There is no specific limitation here. In this embodiment, the pressure sensor 3 is set on the side of the outer surface membrane 2 closer to the housing 1.
[0057] The position of the pressure sensor 3 can be set according to actual needs, and is not limited here. In one embodiment, a receiving groove is provided on the side of the ultrasonic penetration port on the housing 1, and the pressure sensor 3 is disposed in the receiving groove.
[0058] The type of pressure sensor 3 is not limited. In one embodiment, the pressure sensor 3 is a flexible thin-film pressure sensor 3.
[0059] The working principle of this embodiment will now be explained. The transducer of the treatment head operates, emitting ultrasonic signals that pass through the sound-conducting medium, the ultrasonic penetration port, and the outer surface membrane 2 to the outside of the housing 1. The sound-conducting medium absorbs a portion of the energy of the passing ultrasonic signals. After absorbing energy, the sound-conducting medium enters a "boiling" state, causing a change in pressure on the outer surface membrane 2. The pressure sensor 3 sends the detected pressure value to a designated module to convert the pressure value into an electrical signal (which can be voltage or current). This signal is then compared with a preset electrical signal. If the electrical signal is less than the preset signal, the acoustic power is too low; if the electrical signal is greater than the preset signal, the acoustic power is too high. The input electrical signal of the treatment head is controlled to stabilize the acoustic power value at the target acoustic power value.
[0060] In this embodiment, the treatment head is equipped with a pressure sensor 3, which is connected to the outer surface membrane 2. When the transducer in the treatment head is working, the sound-conducting medium absorbs energy and enters a "boiling" state. At this time, the pressure of the sound-conducting medium on the outer surface membrane 2 changes, causing the outer surface membrane 2 to deform under the force. Since the pressure sensor 3 is connected to the outer surface membrane 2, it detects the pressure value and can then adjust the sound power value based on the pressure value to stabilize the sound power value at the target sound power value. This ensures that the sound power does not fluctuate wildly, resulting in a more stable sound power, higher treatment efficiency, and a better user experience.
[0061] The above describes a treatment head according to an embodiment of this application. The following describes a treatment device according to an embodiment of this application. Please refer to... Figure 4 One embodiment of the treatment device in this application includes the treatment head as described above, and further includes: a processing module and a driving module;
[0062] The input end of the treatment head is connected to the output end of the drive module, the output end of the treatment head is connected to the input end of the processing module, and the output end of the processing module is connected to the input end of the drive module.
[0063] The treatment head is used to detect the pressure value of the sound guiding medium on the outer surface membrane 2 of the treatment head. The processing module is used to control the output of the drive module according to the pressure value and the pre-stored calibration value, so as to adjust the acoustic power of the transducer of the treatment head. The calibration value can be pressure, current, voltage, etc., which can be converted and compared by a pre-set relationship function.
[0064] The working principle of this embodiment will now be explained. The transducer of the treatment head operates, emitting ultrasonic signals and simultaneously detecting the pressure value of the sound-conducting medium on the outer surface membrane 2. This pressure value is output to the processing module. If the calibration value is a voltage value, the pressure value is first converted to the corresponding voltage value, and then compared with the calibration value. Since the calibration value corresponds to the target acoustic power value, if the value is greater than the calibration value, it indicates that the acoustic power value is greater than the target acoustic power value, and the output of the drive module needs to be reduced to decrease the acoustic power. If the value is less than the calibration value, it indicates that the acoustic power value is less than the target acoustic power value, and the output of the drive module needs to be increased to increase the acoustic power. This process stabilizes the acoustic power value at the target acoustic power value.
[0065] In this embodiment, the treatment head can detect the pressure value of the outer surface membrane 2 when the sound-conducting medium "boils" and feed it back to the processing module. The processing module can adjust the actual sound power value based on the pressure value to stabilize the sound power value at the preset target sound power value, thereby ensuring treatment efficiency and providing users with a better experience.
[0066] Please see Figures 5 to 8 Another embodiment of the treatment device according to the present application includes: a treatment head as described above, and further includes: a processing module, a driving module and a conditioning module;
[0067] The input end of the treatment head is connected to the output end of the drive module, the output end of the treatment head is connected to the input end of the processing module, and the output end of the processing module is connected to the input end of the drive module.
[0068] The treatment head is used to detect the pressure value of the sound guiding medium on the outer surface membrane 2 of the treatment head. The processing module is used to control the output of the drive module according to the pressure value and the pre-stored calibration value, so as to adjust the acoustic power of the transducer of the treatment head. The calibration value can be pressure, current, voltage, etc., which can be converted and compared by a pre-set relationship function.
[0069] The output of the treatment head is connected to the input of the processing module via the conditioning module. Specifically, the conditioning module includes at least one of three units: an amplification unit, a filtering unit, and a shaping unit. If the conditioning module includes multiple units, these units are connected in series. The number of units included in the conditioning module can be set according to actual needs and is not limited here. This embodiment uses an amplification unit, a filtering unit, and a shaping unit as an example, with the amplification unit, filtering unit, and shaping unit connected in series in sequence. The amplification unit is connected to the treatment head, and the shaping unit is connected to the processing module.
[0070] Specifically, the amplification unit includes: a first resistor R1, a second resistor R2, a third resistor R3, a first capacitor C1, and a first operational amplifier U1. The amplification unit can amplify the signal.
[0071] One end of the first resistor R1 serves as the input terminal of the amplification unit (connected to the treatment head in this embodiment), and the other end of the first resistor R1 is connected to the non-inverting input terminal of the first operational amplifier U1. The inverting input terminal of the first operational amplifier U1 is connected to the second terminal of the second resistor R2, the first terminal of the third resistor R3, and the first terminal of the first capacitor C1, respectively. The first terminal of the second resistor R2 is connected to the power supply terminal (5V in this embodiment). The output terminal of the first operational amplifier U1 is connected to the second terminal of the third resistor R3 and the second terminal of the first capacitor C1, respectively. The output terminal of the first operational amplifier U1 serves as the output terminal of the amplification unit (connected to the input terminal of the filtering unit in this embodiment).
[0072] The filtering unit includes a fourth resistor R4 and a second capacitor C2, and the filtering unit is capable of filtering the signal.
[0073] The first end of the fourth resistor R4 serves as the input end of the filtering unit (in this embodiment, it is connected to the output end of the amplification unit), the second end of the fourth resistor R4 is grounded through the second capacitor C2, and the second end of the fourth resistor R4 serves as the output end of the filtering unit (in this embodiment, it is connected to the input end of the shaping unit).
[0074] The shaping unit includes: a fifth resistor R5, a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, a third capacitor C3, and a second operational amplifier U2. The shaping unit can adjust the shape of the signal.
[0075] The first end of the fifth resistor R5 is connected to the power supply terminal. The inverting input terminal of the second operational amplifier U2 is connected to the second end of the fifth resistor R5 and the first end of the sixth resistor R6, respectively. The second end of the sixth resistor R6 is grounded. The first end of the seventh resistor R7 serves as the input terminal of the shaping unit (in this embodiment, it is connected to the output terminal of the filtering unit). The non-inverting input terminal of the second operational amplifier U2 is connected to the second end of the seventh resistor R7, the first end of the third capacitor C3, and the first end of the eighth resistor R8, respectively. The output terminal of the second operational amplifier U2 is connected to the second end of the third capacitor C3 and the second end of the eighth resistor R8, respectively. The output terminal of the second operational amplifier U2 serves as the output terminal of the shaping unit (in this embodiment, it is connected to the processing module).
[0076] The working principle of this embodiment will now be explained. The transducer of the treatment head operates, emitting ultrasonic signals and simultaneously detecting the pressure value of the sound-conducting medium on the outer surface membrane 2. This pressure value is amplified by the amplification unit, filtered by the filtering unit, and shaped by the shaping unit before being output to the processing module. If the calibration value is a voltage value, the pressure value must first be converted to the corresponding voltage value, and then compared with the calibration value. Since the calibration value corresponds to the target acoustic power value, if the value is greater than the calibration value, it indicates that the acoustic power value is greater than the target acoustic power value, and the output of the drive module needs to be reduced to decrease the acoustic power. If the value is less than the calibration value, it indicates that the acoustic power value is less than the target acoustic power value, and the output of the drive module needs to be increased to increase the acoustic power. This process stabilizes the acoustic power value at the target acoustic power value. For example, if the calibration value is 3V, after detecting the pressure value, it is converted to the corresponding 2.5V according to a preset relationship function. Comparing 2.5V with 3V, 2.5 < 3, it indicates that the actual acoustic power value is less than the target acoustic power value, and the acoustic power needs to be increased.
[0077] In this embodiment, the treatment head can detect the pressure value of the outer surface membrane 2 when the sound-conducting medium "boils". After signal conditioning such as amplification, filtering and shaping, the pressure value is fed back to the processing module. The processing module can adjust the actual sound power value based on the pressure value to stabilize the sound power value at the preset target sound power value, thereby ensuring treatment efficiency and providing users with a better experience.
[0078] The sound power adjustment method of this application is described below. Please refer to [link / reference]. Figure 9 One embodiment of the acoustic power adjustment method of this application is applied to the treatment device as described above, comprising:
[0079] 901. When the transducer of the treatment device is working, detect the pressure value of the sound guiding medium in the treatment device on the outer surface membrane of the treatment device;
[0080] When the transducer of the treatment device is working, it detects the pressure value of the sound-conducting medium on the outer surface membrane of the treatment device. Specifically, when the transducer is working, the sound-conducting medium absorbs part of the energy of the ultrasonic signal and "boils," which changes the pressure on the outer surface membrane, causing a change in the deformation of the outer surface membrane. Therefore, the pressure sensor can detect the pressure value of the outer surface membrane.
[0081] 902. Obtain the target electrical signal corresponding to the pressure value based on the pressure value;
[0082] The target electrical signal corresponding to the pressure value is obtained based on the pressure value. Specifically, based on a preset relationship function between pressure value and electrical signal, the corresponding target electrical signal can be obtained from the pressure value. After obtaining the target electrical signal, it can be preprocessed to facilitate subsequent comparison. The target electrical signal can be a voltage signal or a current signal; the specific type is not limited here.
[0083] 903. If the value of the target electrical signal is greater than the preset calibration signal value, then reduce the value of the input electrical signal of the transducer to reduce the acoustic power of the ultrasonic signal emitted by the transducer.
[0084] If the target electrical signal value is greater than the preset calibration signal value, the input electrical signal value of the transducer is reduced to decrease the acoustic power of the ultrasonic signal emitted by the transducer. Specifically, if the target electrical signal value is greater than the calibration signal value, it means that the acoustic power value is greater than the target acoustic power value, and the input electrical signal value of the transducer needs to be reduced to decrease the acoustic power.
[0085] 904. If the value of the target electrical signal is less than the preset calibration signal value, increase the value of the input electrical signal of the transducer to increase the acoustic power of the ultrasonic signal emitted by the transducer.
[0086] If the target electrical signal value is less than the preset calibration signal value, the input electrical signal value of the transducer is increased to improve the acoustic power of the ultrasonic signal emitted by the transducer. Specifically, if the target electrical signal value is less than the calibration signal value, it means that the acoustic power value is less than the target acoustic power value, and the input electrical signal value of the transducer needs to be increased to increase the acoustic power.
[0087] In this embodiment, when the transducer of the treatment device is working, the pressure value of the sound-conducting medium on the outer surface membrane of the treatment device is first detected. Then, a target electrical signal corresponding to the pressure value is obtained. If the value of the target electrical signal is greater than a preset calibration signal value, the value of the input electrical signal of the transducer is reduced to decrease the acoustic power of the ultrasonic signal emitted by the transducer; if the value of the target electrical signal is less than the preset calibration signal value, the value of the input electrical signal of the transducer is increased to increase the acoustic power of the ultrasonic signal emitted by the transducer. By reflecting the acoustic power through the pressure value, the actual acoustic power value is stabilized at the target acoustic power value, improving treatment efficiency and ensuring treatment stability.
[0088] Please see Figure 10 Another embodiment of the acoustic power adjustment method of this application, applied to the above-mentioned treatment device, includes:
[0089] 1001. When the transducer of the treatment device is working, detect the pressure value of the sound guiding medium in the treatment device on the outer surface membrane of the treatment device;
[0090] When the transducer of the treatment device is working, it detects the pressure value of the sound-conducting medium on the outer surface membrane of the treatment device. Specifically, when the transducer is working, the sound-conducting medium absorbs part of the energy of the ultrasonic signal and "boils," which changes the pressure on the outer surface membrane, causing a change in the deformation of the outer surface membrane. Therefore, the pressure sensor can detect the pressure value of the outer surface membrane.
[0091] 1002. The electrical signal to be processed, converted from the pressure value, is amplified, shaped, and filtered to obtain the target electrical signal;
[0092] The electrical signal to be processed, converted from the pressure value, is amplified, shaped, and filtered to obtain the target electrical signal. Specifically, based on a preset relationship function between the pressure value and the electrical signal, the electrical signal to be processed corresponding to the pressure value is first obtained. Then, the electrical signal to be processed is amplified, filtered, and shaped to obtain the target electrical signal. The electrical signal can be a voltage signal, a current signal, etc., and is not limited here.
[0093] 1003. If the value of the target electrical signal is greater than the preset calibration signal value, then reduce the value of the input electrical signal of the transducer to reduce the acoustic power of the ultrasonic signal emitted by the transducer.
[0094] If the target electrical signal value is greater than the preset calibration signal value, the input electrical signal value of the transducer is reduced to decrease the acoustic power of the ultrasonic signal emitted by the transducer. Specifically, if the target electrical signal value is greater than the calibration signal value, it means that the acoustic power value is greater than the target acoustic power value, and the input electrical signal value of the transducer needs to be reduced to decrease the acoustic power. The input electrical signal can be a voltage signal or a current signal; there is no specific limitation here.
[0095] 1004. If the value of the target electrical signal is less than the preset calibration signal value, the value of the input electrical signal of the transducer is increased to improve the acoustic power of the ultrasonic signal emitted by the transducer.
[0096] If the target electrical signal value is less than the preset calibration signal value, the input electrical signal value of the transducer is increased to improve the acoustic power of the ultrasonic signal emitted by the transducer. Specifically, if the target electrical signal value is less than the calibration signal value, it means that the acoustic power value is less than the target acoustic power value, and the input electrical signal value of the transducer needs to be increased to increase the acoustic power.
[0097] The following example illustrates this embodiment. When the transducer is working, the pressure value of the sound-conducting medium on the outer surface membrane changes due to the "boiling" of the sound-conducting medium. This pressure value, for example, 0.5N, is obtained and converted into the corresponding 2.5V based on a preset relationship function. The 2.5V signal is then amplified, filtered, shaped, and conditioned to obtain a 5V signal. The calibration value is 6V. Since 5 < 6, it indicates that the current sound power is too low.
