Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Non-conflicting ones of the following embodiments may be arbitrarily combined.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a first embodiment of a control output circuit board according to the present application. Wherein, in this embodiment, the control output circuit board 1 includes: the power supply circuit 10, the protection output circuit 20, the detection circuit 30 and the main control circuit 40.
The power circuit 10 is used for providing a power signal to supply power to the control output circuit board 1. The protection output circuit 20 is coupled to the power circuit 10, and the protection output circuit 20 is externally connected with a first electrode plate and a second electrode plate to electrically connect the first electrode plate and the second electrode plate through an electric conductor, for example, when a conductive loop is formed with a human body through the first electrode plate and the second electrode plate, a detection signal is generated to be able to send the detection signal to the detection circuit 30.
The detection circuit 30 is coupled to the power circuit 10 and the protection output circuit 20, so as to further adjust the detection output signal output by the detection circuit 30 to the main control circuit to a set level state when receiving the detection signal sent by the protection output circuit 20, for example, adjust the detection output signal from a high level to a low level, or adjust the low level to a high level, so as to send to the main control circuit 40.
The main control circuit 40 is coupled to the power circuit 10, the protection output circuit 20 and the detection circuit 30, so as to send a working current to the protection output circuit 20 when detecting that the detection output signal output by the detection circuit 30 to the main control circuit 40 is in a set level state, where the protection output circuit 20 can be understood as a load output circuit to be able to output a corresponding load power, thereby implementing a corresponding function.
When the main control circuit 40 detects that the level state of the detection output signal output to the main control circuit 40 by the detection circuit 30 changes frequently, the main control circuit stops sending the working current to the protection output circuit 20, so as to avoid frequently stopping or starting the working current of the protection output circuit 20, and frequently starting and stopping the control output circuit board 1 to cause damage to the corresponding circuit.
In a specific embodiment, the control output circuit board 1 is used in a low-frequency micro-current massage apparatus, so that the massage apparatus can adjust the operation output of the massage apparatus through wearing detection of the corresponding user. The low-frequency micro-current massage device includes an EMS (Electromagnetic sensitivity) circuit and a microcontroller, i.e., a protection output circuit 20 and a main control circuit 40. EMS circuit is connected with microcontroller's EMS signal output part, and little electric current massage appearance of low frequency is still including wearing detection circuitry, also be the detection circuitry 30 in control output circuit board 1, and should wear detection circuitry's input and connect the output at EMS circuit, be used for detecting whether EMS circuit switches on, in order to generate corresponding detection signal of wearing, also be detection output signal, the output of wearing detection circuitry connects microcontroller wears detection signal input, be used for the output to wear detection signal to microcontroller, from this can know, it can detect user's the situation of wearing to wear detection circuitry, and feed back to the operation of microcontroller auxiliary adjustment massage appearance, in order to realize intelligent control.
It can be understood that when the output end of the wearing detection circuit outputs the effective wearing detection signal, the microcontroller controls the EMS signal output end to continuously output, and when the output end of the wearing detection circuit outputs the ineffective wearing detection signal, the microcontroller controls the EMS signal output end to stop outputting, therefore, the effect that when a user wears well, two electrode plates are attached to a human body to form a passage, the EMS signal output end is controlled to continuously output, and when the user does not wear well or does not wear the electrode plates, the output is cut off, so that the intelligent control of the massager is realized, and the power supply is saved.
Optionally, the microcontroller, that is, the main control circuit 40 further includes a timer module, so as to control the corresponding massage apparatus to shut down after receiving the invalid wearing detection signal and within a preset timing time, when the valid wearing detection signal is not received yet, thereby avoiding power waste due to continuous detection of the wearing detection circuit or standby of the product.
When the microcontroller receives the repeatedly switched effective wearing detection signal or ineffective wearing detection signal within the preset time, the microcontroller controls the EMS signal output end to stop outputting, so that the EMS signal output end is controlled to continuously output only when the continuous effective wearing detection signal is detected. It can be understood that, in the process that the user wears the massage apparatus on the neck after starting up and adjusts the wearing position, the state detected by the wearing detection circuit may be an effective wearing detection signal or an ineffective wearing detection signal which is repeatedly switched, and the EMS signal output should be suspended to reduce the pricking feeling caused by poor contact.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a control output circuit board according to a second embodiment of the present application. In this embodiment, on the basis of the first embodiment of the control output circuit board provided in this application, the protection output circuit 20 further includes a first working sub-circuit 210 and a second working sub-circuit 220 coupled to each other.
The first working sub-circuit 210 and the second working sub-circuit 220 are coupled to the power supply circuit 10, the detection circuit 30 and the main control circuit 40, so that when the main control circuit 40 detects that the detection output signal output from the detection circuit 30 to the main control circuit 40 is in a set level state, that is, when the first electrode sheet and the second electrode sheet are electrically connected through a conductor, for example, the first electrode sheet and the second electrode sheet are electrically connected through a human body and send a detection signal to the detection circuit 30, the first working sub-circuit 210 and the second working sub-circuit 220 alternately send working currents to the first working sub-circuit 210 and the second working sub-circuit 220, so that the first working sub-circuit 210 and the second working sub-circuit 220 alternately output load power.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a control output circuit board according to a third embodiment of the present application. In this embodiment, on the basis of the first embodiment of the control output circuit board provided in the present application, the detection circuit 30 further includes a filter sub-circuit 310.
The filter sub-circuit 310 is coupled to the protection output circuit 20, so as to filter out the corresponding interference signal when the protection output circuit 20 sends the detection signal to the detection circuit 30. Thus, the filter sub-circuit 310 can be understood as a resonant circuit, and since the protection output circuit 20 is switched on and off rapidly to generate an interference signal, the filter sub-circuit 310 can filter out a corresponding high-frequency interference signal when receiving a corresponding detection signal.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a fourth embodiment of the control output circuit board of the present application. In this embodiment, on the basis of the third embodiment of the control output circuit board provided in the present application, the detection circuit 30 further includes a voltage clamp sub-circuit 320.
The voltage clamping sub-circuit 320 is coupled to the protection output circuit 20 and connected in parallel to the filtering sub-circuit 310, so as to suppress an instantaneous high-voltage signal sent to the detection circuit when the protection output circuit 20 is switched on and off, thereby protecting the detection circuit 30.
With continued reference to fig. 5, fig. 5 is a schematic structural diagram of an embodiment of a detection circuit in the control output circuit board in fig. 4.
The filter sub-circuit 310 includes a filter capacitor C and a sampling resistor R1 connected in parallel to form a resonant circuit, so as to filter out corresponding interference signals. The voltage clamping sub-circuit 320 is connected in parallel with the filtering sub-circuit 310, and includes a first diode D1 and a second diode D2 connected in series, so as to suppress the transient high voltage signal sent to the detection circuit 30 when the protection output circuit 20 is switched on and off, thereby ensuring the voltage stability of the corresponding detection signal.
Referring to fig. 6, fig. 6 is a schematic structural diagram of another embodiment of the detection circuit in the control output circuit board in fig. 4. In this embodiment, on the basis of the first embodiment of the control output circuit board provided in the present application, the detection circuit 30 further includes a switch tube Q, a protection resistor R2, and a pull-up resistor R3.
The protection resistor R2 is connected with the power circuit 10, the collector of the switch tube Q is connected with the protection resistor R2 and the main control circuit 40, the emitter of the switch tube Q is grounded, and the base of the switch tube Q is connected with the pull-up resistor R3 and is connected with the protection output circuit 20 through a pull-up resistor R3.
Alternatively, the detection circuit 30 pulls up the voltage at the detection signal input terminal from a low level to a high level through the pull-up resistor R3 to convert the detection signal into a high-level detection output signal. The detection output signal is active at a high level and inactive at a low level, so that when the detection output signal is input to the main control circuit 40, the main control circuit 40 outputs a working current to the protection output circuit 20 when the detection output signal is at the high level, and does not output a corresponding working current when the detection output signal is at the low level. It can be understood that when the detection output signal is used as a wearing detection signal in the massager, the detection output signal can correspondingly realize that when the massager is not worn, the corresponding detection signal cannot be generated with a human body through the first electrode plate and the second electrode plate, the low massager does not work, and when the massager is worn, the corresponding detection signal can be generated, so that the massager works.
Referring to fig. 7, fig. 7 is a schematic structural diagram of a seventh embodiment of the control output circuit board of the present application. In this embodiment, on the basis of the first embodiment of the control output circuit board provided in this application, the control output circuit board 1 further includes an operating state indicating sub-circuit 50.
The working status indicating sub-circuit 50 is coupled to the main control circuit 40, and the working status indicating sub-circuit 50 includes an indicator light, so that when the main control circuit 40 detects that the detection output signal output by the detection circuit 30 to the main control circuit 40 is in the set level state, a control signal is sent to the working status indicating sub-circuit, so that the corresponding indicator light is displayed in a first color, and when the main control circuit 40 detects that the corresponding detection output signal is not in the set level state, the indicator light is adjusted and displayed in a second color, so as to visually display the operating status of the current control output circuit board 1. The first color and the second color may be any two different colors of red, green, yellow, and the like, which is not limited in this application.
