Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, specifically a fascia gun and its control circuit. Background Technology

[0002] A fascia gun is a soft tissue rehabilitation tool that uses high-frequency impacts to relax the body's soft tissues. Because different parts of the body have different tolerance levels, the vibration frequency of a fascia gun can generally be adjusted when using it. At the same time, it is important to pay attention to the method of use and select an appropriate vibration frequency according to the characteristics of the body's tissues to avoid damaging the tissues.

[0003] While current fascia guns offer multiple vibration frequencies, their frequency levels are relatively fixed. The vibration frequency of the fascia head can only be adjusted via buttons on the fascia gun, resulting in a relatively low level of intelligence. It is difficult to add personalized intelligent algorithms to the existing hardware to control it and set more comprehensive vibration frequencies according to different body tissues. Furthermore, the grip angle of current fascia guns is relatively uniform, making it difficult for users to choose different angles when massaging different parts of the body, leading to discomfort when holding the fascia gun.

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] To address the relatively low level of intelligence in current fascia guns, the difficulty in adding personalized intelligent algorithms to control them based on existing hardware, and the limited grip angles of existing fascia guns, this utility model provides a fascia gun, such as... Figure 1 As shown, the device includes a rod-shaped first handheld part 1 serving as a mounting carrier. A vibrating fascia head 2 is mounted at one end of the first handheld part 1. The reciprocating vibration direction of the fascia head 2 is the same as the extension direction of the first handheld part 1. A rod-shaped second handheld part 3, perpendicular to the fascia head 2, is positioned between the end of the first handheld part 1 away from the first handheld part 1 and the end of the first handheld part 1 with the fascia head 2. A rod-shaped third handheld part 4 is positioned between the end of the second handheld part 3 away from the first handheld part 1 and the end of the first handheld part 1 with the fascia head 2. The angle between the third handheld part 4 and the first handheld part 1 is 30° to 60°. This angle is designed to ensure user comfort and prevent difficulty in fitting the user's hand into the enclosed triangular area. When using the fascia gun, the user can choose different gripping points depending on the area to be massaged, aligning the fascia head 2 with the area to be massaged. This allows for more convenient massage of the area. The triangular structure formed by the first gripping part 1, the second gripping part 3, and the third gripping part 4 is equivalent to having three gripping points on a circle. In addition, considering the way a person holds the fascia gun to a specific part of their body, three specific gripping points are designed for use, allowing the user to choose from more angles and select a more comfortable angle to hold the fascia gun, thus achieving massage of specific parts of the body.

[0032] The fascia gun is also equipped with a switch 11, which is used to control the fascia gun to start and stop.

[0033] To facilitate charging and data transfer and settings, a USB interface 12 is also provided on the fascia gun.

[0034] This utility model also provides a control circuit for controlling a fascia gun, such as Figure 2 As shown, the control circuit includes a motor for controlling the vibration frequency of the fascia head 2, and further includes:

[0035] The voice processing module 5 is used to collect and process voice signals to obtain voice signals, thereby facilitating the signal processing module 7 to obtain executable instructions; the manual switching module 6 is used to acquire manual signals input by the user and select one of the voice signals and the user-input manual signals to input into the signal processing module 7; the signal processing module 7 is used to process the input voice signals and manual signals and change the drive voltage output to the motor to change the vibration frequency of the fascia head 2, thereby realizing both manual and voice control of the vibration frequency of the fascia head 2. The voice signals are input by the user through the voice processing module 5, and the manual signals are control signals manually input by the user through buttons or other means in the manual switching module 6. Thus, through the cooperation of the above modules, both voice and manual control of the fascia head 2 of the fascia gun can be achieved. The processing of voice signals is mainly done through hardware, and the user can also edit better processing code to better achieve the purpose of controlling the vibration frequency of the fascia head 2.

[0036] The signal processing module 7 acquires sound signals and manual signals, and drives the motor to rotate. Therefore, a structure is provided to achieve this purpose, such as... Figure 3 As shown, the signal processing module 7 includes an audio processing chip and a motor control chip for controlling the motor. The audio processing chip used here is model SPCE061A, and the motor control chip is model TMS320LF2407A. The audio processing chip is connected to the receiving end RX and the transmitting end TX of the motor control chip through the transmitting end IOB10 and the receiving end IOB7, respectively. A speed control module 8 is also provided between the audio processing chip and the motor control chip to control the voltage of the power signal input into the motor control chip. The speed control module 8 controls the voltage input into the motor control chip, thereby controlling the vibration speed of the fascia head 2. Furthermore, based on the audio processing chip of the signal processing module 7, new voice processing methods can be developed, thereby providing richer voice control methods to control the fascia head 2.

[0037] To further illustrate the structure of the speed control module 8, which controls the voltage input to the motor control chip, the speed control module 8 includes a resistor R1 and a transistor Q1 connected in series between several IOB interfaces of the audio processing chip and the ADCIN interface of the motor control chip. The emitter of transistor Q1 is connected to the power supply VCC, the base of transistor Q1 is connected to the resistor R1, and the collector of transistor Q1 is connected to the ADCIN interface of the motor control chip. The resistor R1 on each IOB interface is different. Figure 6As shown, the IOB8, IOB9, IOB10, and IOB11 interfaces of the audio processing chip can be connected to the A1, A2, A3, and A4 interfaces in the circuit, respectively. After receiving a manual signal or a voice signal, the audio processing chip can control the conduction of the transistor Q1 in the corresponding circuit by controlling the different levels of the IOB8, IOB9, IOB10, and IOB11 interfaces. This allows resistors R1 with different resistance values ​​to be connected to the circuit, thereby controlling the voltage input to the motor control chip and thus controlling the voltage input to the motor to control the vibration frequency of the fascia head 2.

[0038] The voice processing module 5 is used to process the user's input voice signal and convert it into a digital signal, such as... Figure 4 As shown, the voice processing module 5 includes capacitor C28, microphone MIC, and capacitor C29 connected sequentially to the MICP and MICN ports of the audio processing chip. Resistors R20 and R21 are connected to the MICP and MICN ports of the audio processing chip and the VAREF port, respectively. Capacitors C30 and C31 are connected in parallel and grounded on the VAREF port of the audio processing chip. A grounded resistor R22 is connected between capacitor C29 and microphone MIC. The user's voice signal is converted into an electrical signal by microphone MIC and then input to the internal preamplifier of SPCE061A. The internal automatic gain control circuit AGC of SPCE061A can track and monitor the audio signal level output by the preamplifier in real time. When the input signal decreases, the AGC circuit can automatically increase the gain of the amplifier, and vice versa. This keeps the signal entering A / D at the optimal level and minimizes clipping. The resistors and capacitors in the circuit play a filtering role. The circuit shown on the left side of the SPCE061A chip can also be configured as needed to play voice through the speaker, thereby facilitating human-computer voice interaction.

[0039] To enable manual signal input, and the switching between voice and manual signal input, such as... Figure 5 As shown, the manual switching module 6 is connected to several interfaces of the audio processing chip via a mode switching switch SW. The mode switching switch SW can be a model SW DIP-5. Pins 6, 7, 8, 9, and 10 of the mode switching switch SW are all grounded. Figure 2 As shown, one end of the mode switching switch SW is grounded, and the other end is connected to pin IOB11 of the SPCE061A. When pin IOB11 of the SPCE061A microcontroller is low, the controller is in voice mode; when it is high, it is in manual mode. Pins IOB12, IOB13, IOB14, and IOB15 are used for manual signal input to control the increase and decrease of the motor speed, thereby controlling the vibration frequency of the fascia head 2.
