Description

Technical Field

[0001] This invention relates to the field of beauty device technology, and in particular to a gradually increasing body-sensing control beauty device and control method. Background Technology

[0002] Existing beauty devices typically provide a fixed output intensity at each level. When users directly use the highest level, they are prone to experiencing a strong stinging sensation, affecting the user experience. Although some beauty devices attempt to alleviate discomfort through intensity adjustment, this method relies on manual operation by the user and cannot provide a gradually increasing experience from zero every time it is applied to the skin. Therefore, comfort and intelligence are still insufficient.

[0003] To address the technical problem of fixed output intensity at each level in existing beauty devices, this invention proposes a beauty device and control method. The aim is to improve user comfort and adaptability through gradual output and skin contact detection, avoiding the stinging sensation upon skin contact. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a gradually increasing somatosensory control beauty device and control method. By gradually increasing the output of electrical stimulation energy over a certain period of time and combining it with skin contact detection, the user can experience a gradually increasing somatosensory sensation each time the device is applied to the skin, thereby better adapting and avoiding the stinging sensation at the moment of application.

[0005] The technical solution of the present invention provides a gradually increasing body-sensing control beauty device, comprising: Electrical stimulation energy output module, used to output electrical stimulation energy to the skin; The skin contact detection module is used to detect whether the beauty device is in close contact with the skin; The controller is connected to the electrical stimulation energy output module and the skin contact detection module respectively. It is used to control the skin contact detection module to detect whether the beauty device is in contact with the skin, and after detecting that the beauty device is in contact with the skin, it controls the electrical stimulation energy output module to output electrical stimulation energy in a gradually increasing manner within a preset time until the preset target intensity is reached.

[0006] Furthermore, the gradually increasing output includes multiple output stages, in which the electrical stimulation energy output intensity and / or the minimum pulse on-time of the electrical stimulation energy gradually increase.

[0007] Furthermore, the gradually increasing output includes: If the running time of the beauty device is greater than 0 but less than the first preset time threshold, there is no electrical stimulation energy output; If the running time is greater than the first preset time threshold and less than the second preset time threshold, the first preset electrical stimulation energy is output. If the running time is greater than the second preset time threshold and less than the third preset time threshold, the second preset electrical stimulation energy is output, and the second preset electrical stimulation energy is greater than the first preset electrical stimulation energy. If the running time is greater than the third preset time threshold and less than the fourth preset time threshold, the third preset electrical stimulation energy is output, and the third preset electrical stimulation energy is greater than the second preset electrical stimulation energy. If the running time is greater than the fourth preset time threshold, the preset target intensity is output.

[0008] Furthermore, the beauty device includes at least two electrodes, and also includes: A switching module is used to switch the connection between the electrical stimulation energy output module or the skin-touch detection module and the electrode.

[0009] Furthermore, the switching module includes: The first sub-switching unit is used to control the electrical stimulation energy output module to connect with the electrode when it receives the electrical stimulation energy output signal from the controller; The second sub-switching unit is used to control the skin-fitting detection module to connect with the electrode when it receives the skin-fitting detection signal from the controller.

[0010] Furthermore, the first sub-switching unit includes a first transistor and a first relay. The base of the first transistor is connected to the controller, the collector of the first transistor is connected to the first terminal of the first relay, the emitter of the first transistor is grounded, and the second terminal of the first relay is connected to the electrode.

The base of the second transistor is connected to the controller, the collector of the second transistor is connected to the first terminal of the second relay, the emitter of the second transistor is grounded, and the second terminal of the second relay is connected to the electrode.

[0011] Furthermore, it also includes: A power supply voltage control module is used to supply power to the electrical stimulation energy output module.

[0012] Furthermore, the electrical stimulation energy output module includes a boost unit, a switching unit, and a waveform adjustment unit connected to the electrodes of the beauty device. The boost unit is used to boost the input current containing the input frequency and output the target voltage containing a square wave. A switching unit, one end of which is connected to the boost unit and the other end of which is connected to the waveform adjustment unit, is used to control the connection or disconnection of the boost unit and the waveform adjustment unit according to the switching signal; A waveform adjustment unit is used to adjust the square wave into a sine wave when the boost unit is connected to the waveform adjustment unit; The controller is also used for: A switching signal is generated based on the input frequency to control the connection or disconnection of the switching unit and the waveform adjustment unit.

[0013] The technical solution of the present invention also provides a control method for the gradually increasing body-sensing control beauty device as described above, comprising: Upon receiving the activation signal of the beauty device, the skin contact detection module is controlled to detect whether the beauty device is in contact with the skin. After detecting that the beauty device is in contact with the skin, the electrical stimulation energy output module is controlled to output electrical stimulation energy in a gradually increasing manner within a preset time until the preset target intensity is reached.

[0014] Furthermore, the gradually increasing output includes multiple output stages, in which the electrical stimulation energy output intensity and / or the minimum pulse on-time of the electrical stimulation energy gradually increase.

[0020] like Figures 1-7 As shown, an embodiment of the present invention provides a gradually increasing body-sensing control beauty device, comprising: Electrical stimulation energy output module 10 is used to output electrical stimulation energy to the skin; Skin contact detection module 20 is used to detect whether the beauty device is in contact with the skin; The controller 30 is connected to the electrical stimulation energy output module 10 and the skin contact detection module 20 respectively. It is used to control the skin contact detection module 20 to detect whether the beauty device is in contact with the skin, and after detecting that the beauty device is in contact with the skin, it controls the electrical stimulation energy output module 10 to output electrical stimulation energy in a gradually increasing manner within a preset time until the preset target intensity is reached.

[0021] Specifically, the progressively stronger body-sensing control beauty device provided in this embodiment of the invention mainly includes an electrical stimulation energy output module 10, a skin-touch detection module 20, and a controller 30.

[0022] The electrical stimulation energy output module 10 is used to output electrical stimulation energy to the skin. For example... Figure 3As shown, the electrostimulation energy output module 10 boosts Vcc_EP and ultimately outputs it to the skin. The core component of the electrostimulation energy output module 10 is the transformer T1, which boosts Vcc_EP to different 60V levels to achieve different effects and sensations. IO_PWM_EP_A and IO_PWM_EP_B are two complementary PWM ports of the main control chip, outputting PWM signals of different frequencies and periods. These signals are applied to the transformer T1 through the EP drive circuit (including resistors, capacitors, and MOSFETs such as R7, R15, Q16, C85, R25, R10, R18, Q17, C86, and R26), and after being boosted, are output to the skin through the electrodes EP+ and EP-.

[0023] The skin contact detection module 20 is used to detect whether the beauty device is in contact with the skin. For example... Figure 4 As shown, R_check_PWM_OUT is a chip port that outputs a PWM signal of a certain frequency. This signal passes through the M4 skin-touch detection circuit and is detected by the two electrodes R_check_V_OUT+ and R_check_V_OUT-. The main control chip detects voltage changes through the R_Check_IN_ADC AD port to determine whether the skin is in contact with the skin.

[0024] The controller 30 is used to receive external commands (such as parameters from a smart headband or mobile app) and coordinate the operation of various modules based on these parameters, particularly controlling the gradual increase in output and somatosensory control of the electrical stimulation energy output module 10, and the activation of the skin contact detection module 20. In this embodiment, the controller 30 can specifically be a microcontroller unit (MCU), such as... Figure 2 As shown, the electrical stimulation energy output module 10 is controlled via the IO_PWM_EP_A and IO_PWM_EP_B ports, and the skin contact detection module 20 is controlled via the R_Check_PWM_OUT port. Within one cycle, when the electrical stimulation energy output module 10 is detected to be off (i.e., not working), the skin contact detection module 20 is controlled to perform skin contact detection. When the beauty device is detected to be on the skin, the electrical stimulation energy output module 10 is controlled to output electrical stimulation energy in a gradually increasing manner within a preset time until a preset target intensity is reached. This cycle repeats until the beauty and skincare steps are completed.

[0025] The electrical stimulation energy described in this invention may include, but is not limited to, electroporation (EP) energy, microcurrent (MC) energy, or electrical muscle stimulation (EMS) energy, to adapt to different beauty needs and application scenarios.

[0026] In this embodiment, by controlling the electrical stimulation energy output module to output electrical stimulation energy in a gradually increasing manner, the user experiences a progressively stronger sensation each time the device is applied to the skin. This improves user comfort and adaptability, avoids instantaneous stinging, and, combined with the skin contact detection module, detects whether the beauty device is in contact with the skin, achieving reliable identification and ensuring user safety and beauty efficacy.

[0027] In one embodiment, the gradually increasing output includes multiple output stages, in which the electrical stimulation energy output intensity and / or the minimum pulse on time of the electrical stimulation energy gradually increase.

[0028] Specifically, when the beauty device detects that it is in contact with the skin, the electrical stimulation energy output does not immediately reach the user's preset target intensity, but gradually increases in stages, and the minimum pulse opening time of the electrical stimulation energy also gradually increases.

[0029] In one embodiment, the progressive enhancement output includes: If the running time of the beauty device is greater than 0 but less than the first preset time threshold, there is no electrical stimulation energy output; If the running time is greater than the first preset time threshold and less than the second preset time threshold, the first preset electrical stimulation energy is output. If the running time is greater than the second preset time threshold and less than the third preset time threshold, the second preset electrical stimulation energy is output, and the second preset electrical stimulation energy is greater than the first preset electrical stimulation energy. If the running time is greater than the third preset time threshold and less than the fourth preset time threshold, the third preset electrical stimulation energy is output, and the third preset electrical stimulation energy is greater than the second preset electrical stimulation energy. If the running time is greater than the fourth preset time threshold, the preset target intensity is output.

[0030] Specifically, taking the TONING (EP) mode as an example, the gradual increase control can be divided into the following stages: • First stage: 0 to 5 units (0 to Ams): No EP energy output.

[0031] • Second stage: A~2Ams (6~10 units): Output 25% of EP energy.

[0032] • Third stage: 2A~3Ams (11~15 units): Output 50% of EP energy.

[0033] • Fourth stage: 3A~4Ams (16~20 units): Output 75% of EP energy.

[0034] • Fifth stage: 4Ams (21 units): Outputs 100% EP energy.

[0035] In MC mode, the gradual increase design is similar, but it also takes into account the changes in the minimum EP pulse on (ON) and off (OFF) times at different levels. For example, in the gradual increase design at Level 5: • First stage: 0~Ams (0~5 units): No EP energy output.

[0036] • Second stage: A~2Ams (6~10 units): Output 25% of EP energy, and the minimum pulse ON time of the electrical stimulation energy is 1ms.

[0037] • Third stage: 2A~3Ams (11~15 units): Output 50% of EP energy, and the minimum pulse ON time of the electrical stimulation energy is 2ms.

[0038] • Fourth stage: 3A~4Ams (16~20 units): Output 75% of EP energy, and the minimum pulse ON time of the electrical stimulation energy is 3ms.

[0039] • Fifth stage: 4Ams~ (21 units~): Output 100% EP energy, and the minimum pulse ON time of the electrical stimulation energy is 5ms.

[0040] The minimum pulse ON time for electrical stimulation energy varies depending on the level (e.g., LV1, LV2, LV3, LV4, LV5). For example, LV1 and LV2 have a minimum pulse ON time of 2ms, LV3 has a minimum pulse ON time of 3ms, LV4 has a minimum pulse ON time of 4ms, and LV5 has a minimum pulse ON time of 5ms. In addition, the output frequency will also change, for example, FREQ1 corresponds to 100ms, FREQ2 corresponds to 200ms, etc.

[0041] In one embodiment, the progressive enhancement output includes: Under a preset output voltage, the output frequency of each output stage gradually increases according to a preset time interval.

[0042] Specifically, different levels (such as LV1, LV2, LV3, LV4, LV5) consist of multiple output frequencies and output voltages. The output voltage is the same for each level, and the output frequency of each level gradually increases according to a preset time interval to minimize skin irritation and improve user comfort. For example, taking LV3 as an example, assuming that the minimum pulse ON time of the electrical stimulation energy of LV3 is 3ms, the output voltage is 5V, the output frequency is 50HZ-100HZ, and the time interval is set to 0.6ms, the gradual increase mode of LV3 outputs a constant 5V output voltage, with the output frequency gradually increasing from 50HZ to 100HZ every 0.6ms.

[0043] In one embodiment, the progressive enhancement output includes: At a preset output frequency, the output voltage of each output stage gradually increases according to a preset time interval.

[0044] Specifically, different levels (such as LV1, LV2, LV3, LV4, LV5) consist of multiple output frequencies and output voltages. Each level has the same output frequency, and the output voltage of each level gradually increases according to preset time intervals to minimize skin irritation and improve user comfort. For example, taking LV3 as an example, assuming that the minimum pulse ON time of the electrical stimulation energy of LV3 is 3ms, the output frequency is 100Hz, and the output voltage is 2V-5V with a time interval of 0.6ms, the gradual increase mode of LV3 outputs the voltage from 2V to 5V at a constant output frequency of 100Hz, with the output voltage gradually increasing from 2V to 5V every 0.6ms.

[0045] In one embodiment, such as Figure 1 As shown, the beauty device includes at least two electrodes 40, and also includes: The switching module 50 is used to switch the connection between the electrical stimulation energy output module 10 or the skin contact detection module 20 and the electrode 40.

[0046] Specifically, in order to reuse the EP+ and EP- electrodes, the switching module 50 switches between the EP output and skin contact recognition functions to ensure that the two functions can share the electrode 40 and work together.

[0047] In one embodiment, such as Figure 1 As shown, to further ensure that the two functions can share electrode 40 and work together, the switching module 50 includes: The first sub-switching unit 51 is used to control the electrical stimulation energy output module 10 to connect with the electrode 40 when it receives the electrical stimulation energy output signal sent by the controller 30. The second sub-switching unit 52 is used to control the skin-fitting detection module 20 to connect with the electrode 40 when it receives the skin-fitting detection signal sent by the controller 30.

[0048] In one embodiment, such as Figure 6 and Figure 7 As shown, the first sub-switching unit 51 includes first transistors Q6 and Q7 and first relays K6 and K7. The bases of the first transistors Q6 and Q7 are connected to the controller 30, the collectors of the first transistors Q6 and Q7 are connected to the first terminals of the first relays K6 and K7, the emitters of the first transistors Q6 and Q7 are grounded, and the second terminals of the first relays K6 and K7 are connected to the electrode 40. The second sub-switching unit 52 includes second transistors Q4 and Q5 and second relays K4 and K5. The bases of the second transistors Q4 and Q5 are connected to the controller 30, the collectors of the second transistors Q4 and Q5 are connected to the first terminals of the second relays K4 and K5, the emitters of the second transistors Q4 and Q5 are grounded, and the second terminals of the second relays K4 and K5 are connected to the electrode 40.

[0049] Specifically, when the EP output is active, IO_Relay6 and IO_Relay7 control the first transistors Q6 and Q7, turning on the first relays K6 and K7, thus connecting the EP output signal to the electrodes. When skin contact detection is performed, IO_Relay4 and IO_Relay5 control the second transistors Q4 and Q5, turning on the second relays K4 and K5, thus connecting the skin contact detection PWM output signal to the electrodes. When the two electrodes come into contact with the skin, the skin generates a certain impedance, forming a circuit.

[0050] In one embodiment, such as Figure 1 and Figure 5 As shown, it also includes: The power supply voltage control module 60 is used to supply power to the electrical stimulation energy output module 10.

[0051] Specifically, the power supply voltage control module 60 is used to supply power to the electrical stimulation energy output module 10, and its circuit structure is as follows: Figure 5 As shown, the power supply voltage control module 60 is mainly composed of a DC-DC chip U5, which steps down the power supply voltage to provide a stable power supply voltage Vcc_EP for the electrical stimulation energy output module 10. Voltage divider resistors R22 and R27 are used to feed the voltage back to U5, ensuring the rated output of Vcc_EP. Filter capacitors C27, C26, C22, C23, and C24 act as voltage regulators for the power supply output.

[0052] In one embodiment, such as Figure 1 As shown, the electrical stimulation energy output module 10 includes a boost unit 11, a switching unit 12, and a waveform adjustment unit 13 connected to the electrodes of the beauty device. The boost unit 11 is used to boost the input current containing the input frequency and output a target voltage containing a square wave. A switching unit 12, one end of which is connected to the boost unit 11 and the other end of which is connected to the waveform adjustment unit 13, is used to control the connection or disconnection of the boost unit 11 and the waveform adjustment unit 13 according to the switching signal; The waveform adjustment unit 13 is used to adjust the square wave into a sine wave when the boost unit 11 is connected to the waveform adjustment unit 13. The controller 30 is also used for: A switching signal is generated based on the input frequency to control the connection or disconnection of the switching unit 12 and the waveform adjustment unit 13.

[0053] Specifically, to optimize the tactile experience, the electrical stimulation energy output module 10 also includes a boost unit 11, a switching unit 12, and a waveform adjustment unit 13. For example... Figure 3 As shown, the boost unit 11, the switching unit 12, and the waveform adjustment unit 13 form a selective capacitor circuit (composed of Q18, R1, K1, C18, etc.). Based on the frequency of the PWM output (e.g., 20kHz, 30kHz, etc.), different selective capacitors are controlled through the IO_Relay port, thereby enabling EP+ and EP- to output sinusoidal waveforms, improving the comfort of the skin feel. R29 and C1 form a filter RC circuit, which, together with the selective capacitors, achieves the sinusoidal waveform output.

[0054] After the user sets the intensity level and massage mode of the beauty device, the controller receives the input frequency, generates a switching signal based on the input frequency, and outputs it to the switching unit. This controls the connection or disconnection between the switching unit and the waveform adjustment unit. For example, when the output switching signal is high, the switching unit controls the boost unit to connect with the waveform adjustment unit; when the output switching signal is low, the switching unit controls the boost unit to disconnect with the waveform adjustment unit. When the boost unit and the waveform adjustment unit are connected, the waveform adjustment unit modulates the square wave output by the boost unit into a sine wave and outputs it to the electrodes of the beauty device, enabling the beauty device to achieve effects such as wrinkle elimination, skin tightening, and body shaping, thus enhancing the user's experience.

[0055] In one preferred embodiment, the controller can calculate the target capacitance based on the input frequency, which is the capacitance value corresponding to the first capacitor, and generate a switching signal for the control switching unit based on the target capacitance, such as... Figure 3 As shown, when the target capacitance calculated by the controller is the sum of capacitors C19 and C31, the controller generates a switching signal that connects capacitors C19 and C31 to the output terminal of the boost unit and disconnects capacitor C18 from the boost unit. This signal is then output to the switching unit, which controls capacitors C19 and C31 to connect to the output terminal of the boost unit and disconnects capacitor C18 from the boost unit. This allows for more accurate matching of the input frequency with the capacitors, outputting a sine wave of the required frequency, and improving user experience and comfort.

[0056] The target capacitance is calculated using the following formula: , Where f is the input frequency; R is the resistance of resistor R29; and C is the capacitance of capacitor C1.

[0057] like Figure 8 As shown, the technical solution of the present invention also provides a control method for the gradually increasing body-sensing control beauty device as described above, comprising: Step S101: After receiving the beauty device start signal, control the skin contact detection module to detect whether the beauty device is in contact with the skin; Step S102: After detecting that the beauty device is in contact with the skin, control the electrical stimulation energy output module to output electrical stimulation energy in a gradually increasing manner within a preset time until the preset target intensity is reached.

[0058] Specifically, after the beauty device is turned on, within one cycle, the controller executes step S101. When it detects that the electrical stimulation energy output module 10 is off (i.e. not working), it controls the skin contact detection module 20 to perform skin contact detection. When it detects that the beauty device is in contact with the skin, the controller executes step S102 to control the electrical stimulation energy output module 10 to output electrical stimulation energy in a gradually increasing manner within a preset time until the preset target intensity is reached. This cycle continues until the beauty and skin care steps are completed.

[0059] In one embodiment, the gradually increasing output includes multiple output stages, in which the electrical stimulation energy output intensity and / or the minimum pulse on time of the electrical stimulation energy gradually increase.

[0060] Specifically, when the beauty device detects that it is in contact with the skin, the electrical stimulation energy output does not immediately reach the user's preset target intensity, but gradually increases in stages, and the minimum pulse opening time of the electrical stimulation energy also gradually increases.

[0061] In one embodiment, the progressive enhancement output includes: If the running time of the beauty device is greater than 0 but less than the first preset time threshold, there is no electrical stimulation energy output; If the running time is greater than the first preset time threshold and less than the second preset time threshold, the first preset electrical stimulation energy is output. If the running time is greater than the second preset time threshold and less than the third preset time threshold, the second preset electrical stimulation energy is output, and the second preset electrical stimulation energy is greater than the first preset electrical stimulation energy. If the running time is greater than the third preset time threshold and less than the fourth preset time threshold, the third preset electrical stimulation energy is output, and the third preset electrical stimulation energy is greater than the second preset electrical stimulation energy. If the running time is greater than the fourth preset time threshold, the preset target intensity is output.

[0062] Specifically, taking the TONING (EP) mode as an example, the gradual increase control can be divided into the following stages: • First stage: 0 to 5 units (0 to Ams): No EP energy output.

[0063] • Second stage: A~2Ams (6~10 units): Output 25% of EP energy.

[0064] • Third stage: 2A~3Ams (11~15 units): Output 50% of EP energy.

[0065] • Fourth stage: 3A~4Ams (16~20 units): Output 75% of EP energy.

[0066] • Fifth stage: 4Ams (21 units): Outputs 100% EP energy.

[0067] In MC mode, the gradual increase design is similar, but it also takes into account the changes in the minimum EP pulse on (ON) and off (OFF) times at different levels. For example, in the gradual increase design at Level 5: • First stage: 0~Ams (0~5 units): No EP energy output.

[0068] • Second stage: A~2Ams (6~10 units): Output 25% of EP energy, and the minimum EP pulse ON time is 1ms.

[0069] • Third stage: 2A~3Ams (11~15 units): Output 50% of EP energy, and the minimum EP pulse ON time is 2ms.

[0070] • Fourth stage: 3A~4Ams (16~20 units): Outputs 75% of EP energy, with a minimum EP pulse ON time of 3ms.

[0071] • Fifth stage: 4Ams~ (21 units~): Outputs 100% EP energy, with a minimum EP pulse ON time of 5ms.

[0072] The minimum pulse ON time of EP varies for different levels (such as LV1, LV2, LV3, LV4, LV5). For example, LV1 and LV2 are 2ms, LV3 is 3ms, LV4 is 4ms, and LV5 is 5ms. In addition, the output frequency will also change, for example, FREQ1 corresponds to 100ms, FREQ2 corresponds to 200ms, etc.

[0073] In one embodiment, the progressive enhancement output includes: Under a preset output voltage, the output frequency of each output stage gradually increases according to a preset time interval.

[0074] Specifically, different levels (such as LV1, LV2, LV3, LV4, LV5) consist of multiple output frequencies and output voltages. The output voltage is the same for each level, and the output frequency of each level gradually increases according to a preset time interval to minimize skin irritation and improve user comfort. For example, taking LV3 as an example, assuming that the minimum pulse ON time of the electrical stimulation energy of LV3 is 3ms, the output voltage is 5V, the output frequency is 50HZ-100HZ, and the time interval is set to 0.6ms, the gradual increase mode of LV3 outputs a constant 5V output voltage, with the output frequency gradually increasing from 50HZ to 100HZ every 0.6ms.

[0075] In one embodiment, the progressive enhancement output includes: At a preset output frequency, the output voltage of each output stage gradually increases according to a preset time interval.

[0076] Specifically, different levels (such as LV1, LV2, LV3, LV4, LV5) consist of multiple output frequencies and output voltages. Each level has the same output frequency, and the output voltage of each level gradually increases according to preset time intervals to minimize skin irritation and improve user comfort. For example, taking LV3 as an example, assuming that the minimum pulse ON time of the electrical stimulation energy of LV3 is 3ms, the output frequency is 100Hz, and the output voltage is 2V-5V with a time interval of 0.6ms, the gradual increase mode of LV3 outputs the voltage from 2V to 5V at a constant output frequency of 100Hz, with the output voltage gradually increasing from 2V to 5V every 0.6ms.

[0077] In one embodiment, the beauty device includes at least two electrodes and further includes: Switch the connection between the electrical stimulation energy output module or the skin-touch detection module and the electrode.

[0078] Specifically, in order to reuse the EP+ and EP- electrodes, the controller switches between the EP output and skin contact recognition functions to ensure that the two functions can share the electrodes and work together.

[0079] The above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, and are not intended to limit them. Although the embodiments of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
