[0060] The following will make a detailed description of a voltage-reducing heart care device of the present invention in conjunction with embodiments and the accompanying drawings.

Inside the bottom case 2, there is a circuit device for generating bioelectric current, a power supply device for providing power, and a charging device 7 connected to the power supply device for charging the power supply device. At the top of the bottom case 2, there is a buckle installation groove 4 for installing a stainless steel buckle 3. A through hole is formed at the bottom of the buckle installation groove 4. The lower part of the stainless steel buckle 3 is fixedly installed in the buckle installation groove 4 of the bottom case 2 through a buckle fixing screw 5 passing through the through hole. At the bottom end of the bottom case 2, there are two through holes 6 that can embed the tail of the charging device 7. The input end of the circuit device is connected to the human body through the fixing screw 14 and the bottom case 2, and the output end of the circuit device is connected to the human body through the contact spring needle 17, the buckle fixing screw 5, and the stainless steel buckle 3 in sequence, thus forming a closed loop of bioelectric current acting on the human body.

[0064] As Figure 4 , Figure 8 , Figure 12 , Figure 13 shown, the bottom case 2 includes a main body case 2.1 with a suspension buckle mounting groove 4 formed at the top end and a through hole 6 formed at the bottom end. In the upper part of the main body case 2.1, more than two mounting posts 2.2 for mounting circuit devices are integrally formed. Mounting screw holes are formed on the mounting posts 2.2.

[0065] A glue accumulation groove 2.5 for embedding a convex edge 1.1 formed around the face cover 1 is formed around the periphery of the bottom case 2 in contact with the face cover 1.

Two hooks 1.2 corresponding to the grooves 2.6 on the case 2 and capable of hooking the grooves 2.6 are formed on each of the left inner side and the right inner side of the convex edge 1.1 of the face cover 1.

[0067] As Figure 13 , Figure 14 , Figure 15As shown, the charging device 7 includes a charging nylon base 7.1, two through holes that penetrate through the front and back and are symmetrically formed on the charging nylon base 7.1. On one side of the charging nylon base 7.1, a convex post 7.2 is integrally formed corresponding to each of the through holes.

A charging spring pin 7.3 is inserted into the through hole of each convex post 7.2. The front end of the charging spring pin 7.3 penetrates through the through hole of the charging nylon base 7.1. When the charging nylon base 7.1 is installed in the bottom shell 2, the two convex posts 7.2 are respectively embedded into the through holes 6 formed at the bottom end of the bottom shell 2. A sealing ring 7.4 is used for sealing between the root of the convex post 7.2 and the bottom shell 2, and it is fixed in the bottom shell 2 through a charging device locking part 11 and an anti - detachment stop post 2.4. After the charging nylon base 7.1 is assembled in place, the sealing ring 7.4 is circumferentially extruded for waterproof sealing. The front end of the charging spring pin 7.3 is in contact connection with the power supply device, and the bottom of the charging spring pin 7.3 is exposed outside the stainless - steel bottom shell 2 for easy charging.

[0068] As Figure 3 , Figure 4 , Figure 16 shown, the circuit device and the power supply device are arranged on a circuit board 13. The circuit board 13 is fixedly connected to the mounting post 2.2 inside the housing 2 through fixing screws 14. After the circuit board 13 is assembled, the contact spring pin 17 is in elastic contact with the buckle fixing screw 5, and the biological current at the output end of the biological electricity circuit B on the circuit board 13 is transmitted to the stainless - steel buckle 3 through the buckle fixing screw 5. The fixing screw 14 is connected to the input end of the biological electricity circuit B on the circuit board 13, and the input end of the biological electricity circuit B on the circuit board 13 is connected to the stainless - steel bottom shell 2 through the fixing screw 14. On the circuit board 13, a charging metal positive contact piece 15a and a charging metal negative contact piece 15b are provided corresponding to the charging device 7 installed at the bottom of the housing 2. The charging metal positive contact piece 15a and the charging metal negative contact piece 15b are respectively connected to the positive and negative poles of the input end of the power supply device. The charging metal positive contact piece 15a and the charging metal negative contact piece 15b are in contact connection with the charging spring pins 7.3 in the corresponding charging device 7. The circuit components 20 of the circuit device include a main control circuit C, a finger sensing circuit E, a biological electricity circuit B, and a function display circuit D that are respectively connected to the main control circuit C. The power supply device includes a charging battery 16 and a charging circuit A connected to the charging battery 16. Among them, the power output terminal VDD of the charging battery 16 is respectively connected to the main control circuit C, the function display circuit D, the biological electricity circuit B, and the finger sensing circuit E. The power input end of the charging circuit A is connected to the charging spring pins 7.3 in the charging device 7 through the charging metal positive contact piece 15a and the charging metal negative contact piece 15b.

[0069] As Figure 17 shown, the main control circuit C is composed of a microprocessor U1. The 8th and 10th pins of the microprocessor U1 are respectively connected to the function display circuit D, the 7th pin is connected to the finger sensing circuit E, the 4th, 5th, 12th and 13th pins are respectively connected to the bioelectric circuit B, the 14th pin is grounded, the 15th pin is connected to the output power supply VDD of the rechargeable battery 16, and a third capacitor C3 and a fourth capacitor C4 are connected in parallel between the 14th and 15th pins.

[0070] As Figure 18 shown, the function display circuit D is composed of a first light-emitting diode G and a second light-emitting diode R. One ends of the first light-emitting diode G and the second light-emitting diode R are commonly connected to the output power supply VDD of the rechargeable battery 16 through a second resistor R2. The other end of the first light-emitting diode G is connected to the 8th pin of the microprocessor U1, and the other end of the second light-emitting diode R is connected to the 10th pin of the microprocessor U1. The first light-emitting diode G and the second light-emitting diode R are arranged on the side of the circuit board 13 close to the face cover 1, and the light emitted by the first light-emitting diode G and the second light-emitting diode R shines out through the colored transparent plastic face cover 1.

[0071] As Figure 19As shown, the bioelectric circuit B includes a Darlington transistor Q1. The emitter e of the Darlington transistor Q1 is grounded. The collector c of the Darlington transistor Q1 is connected to pin 13 of the microprocessor U1.

The other end of the eighth resistor R8 is respectively connected to one ends of the sixth resistor R6 and the seventh resistor R7. The other end of the seventh resistor R7 is connected to the fixing screw 14 for fixing the circuit board 13 and is connected to one end of the human body F through the fixing screw 14 and the housing 2. The other end of the sixth resistor R6, one end of the fifth resistor R5 and one end of the fifth capacitor C5 are commonly connected to pin 12 of the microprocessor U1. The other end of the fifth resistor R5 and the other end of the fifth capacitor C5 are commonly grounded; The other end of the human body F is elastically and contact-connected to the contact spring needle 17 fixedly installed on the lower surface of the circuit board 13 in sequence through the stainless steel buckle 3 and the buckle fixing screw 5.

The other end of the resettable electronic fuse P1 is connected to the connection point between the seventh resistor R7 and the fixing screw 14 through the TVS anti-static transient protection diode D3. The combined action of the resettable electronic fuse P1 and the TVS anti-static transient protection diode D3 can protect the bioelectric circuit B from being broken down by the static high voltage of the human body when it contacts the human body through the stainless steel buckle 3 and the housing 2; The closed-loop bioelectric current formed by the bioelectric circuit B and the human body F is as Figure 22 shown.

[0072] As Figure 20 shown, the finger sensing circuit E includes a touch sensing chip U2.

[0073] As Figure 21As shown in the figure, the charging circuit A includes a charging management chip U3. Pin 1 of the charging management chip U3 is connected to the positive pole of the charging power supply through the tenth resistor R10, the charging metal positive contact piece 15a, and a charging spring pin 7.3. This pin 1 is also grounded through the eighth capacitor C8.

Pins 2 and 3 of the charging management chip U3 are grounded. The charging metal positive contact piece 15a is connected to the charging metal negative contact piece 15b through the seventh capacitor C7. The charging metal positive contact piece 15a is also grounded through the eighth capacitor C8. The charging battery 16 is connected between the charging metal positive contact piece 15a and the ground. The charging battery 16 is fixedly installed on the lower surface of the circuit board 13 through the battery fixing adhesive tape 19. The positive pole of the charging battery 16 is the VDD terminal for powering the system, and the negative pole of the charging battery 16 is the grounding terminal for powering the system.

[0074] In a heart health monitor of the present invention, the microprocessor U1 performs the following processing:

[0075] 1) The microprocessor U1 determines whether the bioelectricity circuit and the external load form a closed current loop. The external load is the human body F or a conductor. The microprocessor U1 judges the voltage value of the PT 3.4 terminal, that is, pin 13:

[0076] (1.1) When the voltage value of PT 3.4 ≥ 1 / 2 of the power supply voltage VDD, the microprocessor U1 determines that no external load is connected between the stainless steel buckle 3 and the housing 2, that is, at least one of the stainless steel buckle 3 and the housing 2 is not in contact with the external load, and the bioelectricity circuit B does not form a closed current loop with the external load. At this time, the microprocessor U1 enters the low-power sleep state after a 2S delay to save battery power. At the same time, the microprocessor U1 turns off PT 1.0, that is, pin 7, and PT 3.5, that is, pin 8, so that the finger induction circuit is not conducting, and the first light-emitting diode G in the function display circuit is not conducting, that is, not lit;

[0077] (1.2) When the voltage value of PT 3.4 < 1 / 3 of the power supply voltage VDD, the microprocessor U1 determines that an external load has been connected between the stainless steel buckle 3 and the housing 2, that is, the stainless steel buckle 3 and the housing 2 are respectively in contact with the external load, and the bioelectricity circuit B forms a closed current loop with the external load. The microprocessor U1 enters the normal working state, connects and starts to identify the voltage value of the bioelectric current obtained at the PT 3.3 terminal, that is, pin 12, after passing through the external load and being fed back. At the same time, the microprocessor U1 turns on PT 1.0, that is, pin 7, and PT 3.5, that is, pin 8, so that the finger induction circuit E is conducting, and the first light-emitting diode G in the function display circuit D is synchronously lit as the finger approaches the finger induction metal sheet 18, or goes out as the finger moves away from the finger induction metal sheet 18;

[0078] 2) The microprocessor U1 determines whether the closed current loop formed by the bioelectricity circuit B and the external load is a normal current value loop or a short - circuit state according to the voltage value fed back after the bioelectric current obtained from the PT 3.3 terminal passes through the external load.

[0079] (2.1) When the voltage value obtained from the PT 3.3 terminal ≥ 1.3V, the microprocessor U1 determines that the closed current loop is in a short - circuit state, that is, the stainless - steel buckle 3 and the housing 2 are in short - circuit contact. Then the microprocessor U1 immediately turns off the output of PT 5.0 and controls PT 3.1, that is, pin 10 intermittently conducts to the ground inside the microprocessor U1. At this time, the second light - emitting diode R in the function display circuit flashes red intermittently for warning. At the same time, the microprocessor U1 turns off PT 1.0 (pin 7) and PT 3.5 (pin 8), making the finger induction circuit non - conductive and the first light - emitting diode G in the function display circuit D non - conductive, that is, not lit.

[0080] (2.2) When the voltage value obtained from PT 3.3 is: 0.2V < voltage value ≤ 1.2V, the microprocessor U1 determines that the human body is normally worn, that is, the bioelectricity circuit B has formed a normal closed current loop with the human body F, as Figure 22 shown. Then the microprocessor U1 maintains the output of PT 5.0. At the same time, the microprocessor U1 connects PT 1.0 (pin 7) and PT 3.5 (pin 8), making the finger induction circuit E conductive. The first light - emitting diode G in the function display circuit D lights up synchronously as the finger approaches the finger - induction metal sheet 18 or goes out as the finger moves away from the finger - induction metal sheet 18.

[0081] (2.3) When the voltage of PT 3.3 < 0.2V, the microprocessor U1 determines that the external load is not connected, that is, the stainless - steel buckle 3 and the housing 2 have separated from the human body F. At this time, the microprocessor U1 enters a low - power sleep state to save battery power. At the same time, the microprocessor U1 turns off PT 1.0 (pin 7) and PT 3.5 (pin 8), making the finger induction circuit E non - conductive and the first light - emitting diode G in the function display circuit non - conductive, that is, not lit.

[0082] 3) The microprocessor U1 determines whether the battery needs to be charged according to the voltage value of the power supply voltage VDD. When the power supply voltage VDD is lower than 2.9V, the microprocessor U1 closes the bioelectricity circuit B by disconnecting the output of PT 5.0, i.e., the output of pin 4, and disconnecting the inputs of PT 3.3, i.e., pin 12 and PT 3.4, i.e., pin 13. The finger sensing circuit E is closed by disconnecting the PT 1.0 terminal, i.e., pin 7 and PT 3.5, i.e., pin 8, so that the first light-emitting diode G in the function display circuit D is not turned on, i.e., does not light up. At the same time, PT 3.1, i.e., pin 10, is grounded in the microprocessor U1 at intervals of 300ms for 400ms to make the second light-emitting diode R in the function display circuit D blink and light up for low-voltage warning to prompt charging in time.

[0083] In a heart health monitor of the present invention, the finger sensing circuit E is used to detect whether a conducting current closed loop is formed between the bioelectricity circuit B and the human body F to confirm whether it is in a normal usable state;

[0084] When the state output pin 3 of the finger sensing circuit E is connected to the PT 1.0 of the microprocessor U1, i.e., pin 7, and the distance between the finger and the finger sensing metal sheet 18 is ≥ 2mm, the state output pin 3 of the touch sensing chip U2 is not grounded inside the touch sensing chip U2, and PT 1.0 is pulled up to a high level by R1. The microprocessor U1 determines that the finger does not touch the finger sensing metal sheet 18 according to PT 1.0 being at a high level, and then disconnects PT 3.5, i.e., pin 8, so that the first light-emitting diode G in the function display circuit is not turned on, i.e., does not light up;

[0085] When the distance between the finger and the finger sensing metal sheet 18 is < 2mm, the touch sensing chip U2 determines that the finger has approached the finger sensing metal sheet 18. The state output pin 3 of the touch sensing chip U2 is grounded inside the touch sensing chip U2, making the PT 1.0 of the microprocessor U1, i.e., pin 7, change from a high level to a low level. The microprocessor U1 confirms that the finger has touched the finger sensing metal sheet 18 according to PT 1.0 being at a low level. At this time, if the bioelectricity circuit B is in a state of forming a normal bioelectric current closed loop with the human body, the PT 3.5 terminal of the microprocessor U1 is grounded inside the microprocessor U1, making the first light-emitting diode G in the function display circuit D turn on and light up, indicating that the bioelectricity circuit B is in a state of forming a normal bioelectric current closed loop with the human body F;
