Description

Technical Field

[0001] This utility model belongs to the field of negative ion electronic device design technology, and relates to a water negative ion health care machine control system and health care machine. Background Technology

[0002] A water negative ion therapy machine is a device that generates negative ions carried by water molecules to improve the air environment and promote human health. However, ordinary water negative ion devices often face static electricity problems during the release of negative ions. When people with dry skin or wearing synthetic clothing are near such devices, touching other objects can easily cause a needle-like static discharge phenomenon. This is due to the transfer of negative ions (negative charges) accumulated on the clothing. Although this negative static electricity is relatively harmless to the human body and can even neutralize some of the positive static electricity generated by household appliances, it still provides an unpleasant experience for the user. For water negative ion therapy machines, if the static electricity problem cannot be effectively solved, it will not only affect the convenience and comfort of daily use but may also limit its application in static-sensitive environments, such as places with many electronic devices. Therefore, researching and developing technologies to effectively suppress or eliminate static electricity generation is crucial for improving the performance and application range of water negative ion therapy machines.

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model pertains.

[0036] It should be noted that, in this document, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The presentation of this phrase in various locations throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will understand that the embodiments described herein can be combined with other embodiments. The term "and / or" as used in the specification of this invention refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations.

[0037] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] In one embodiment, such as Figure 1 As shown, a control system for a water negative ion health care machine is provided, including a power supply module 11, a main control board 12, a power switch 13, a water pump 14, a fan 15, and a water negative ion generating module 16. The main control board 12 is electrically connected to the power supply module 11, the power switch 13, the water pump 14, the fan 15, and the water negative ion generating module 16. The power supply module 11 is used to connect to the mains power grid via a power plug and, after power management, adapt and supply power to the main control board 12. The power switch 13 is used to input power-on, standby, and power-off commands to the main control board 12. The water pump 14 is used to transport ionized water from the water storage source to the water negative ion working area. The water negative ion generating module 16 outputs negative ions to the water negative ion working area to combine with the water mist generated by the ionized water to generate water negative ions. The water negative ion generating module 16 uses a π-type filter, an isolated power supply, and a static charge suppression and elimination network to eliminate static charge. The fan 15 is used to transport the water negative ions to the remote end of the device. The main control board 12 is used for data processing and command control of the whole machine.

[0039] It is understood that in this embodiment, the power supply module 11, main control board 12, overall switch 13, water pump 14, and conveying fan 15 can all be existing circuit modules in the field, such as the corresponding circuit modules existing on the control circuit board of the previous generation of water negative ion health care machine. Here, the circuit structure of the water negative ion generating module 16 is improved, mainly by designing and introducing a π-type filter, an isolation power supply, and a static charge suppression and elimination network in the control circuit of the negative ion generator to perform deep static charge elimination on the control circuit of the negative ion generator. Among them, the π-type filter can adopt the classic structure of two capacitors and one inductor, or a new structure improved on the basis of the classic structure. The isolation power supply can adopt an existing DC / DC module power supply. By introducing an isolation power supply after the π-type filter and before the static charge suppression and elimination network, and in conjunction with the π-type filter to avoid mutual interference between circuits, it is ensured that the static electricity, interference signals, and pulses generated by the negative ion generator are isolated, so that the front-end control circuit is not affected by the static electricity, crosstalk, and radiation interference of the back-end. The static charge suppression and elimination network mainly uses a network of diodes and capacitors to absorb and discharge static charge in the circuit. Combined with a π-type filter and an isolation power supply, it thoroughly enhances the circuit's ability to eliminate electrostatic interference.

[0040] The aforementioned water negative ion health care machine control system, based on the control system circuit consisting of power module 11, main control board 12, machine switch 13, water pump 14, conveying fan 15, and water negative ion generating module 16 as the main circuit components, has undergone a new design for the water negative ion generating module 16. It employs a π-type filter to filter out residual voltage fluctuation interference in the power supply voltage supplied by power module 11 to the water negative ion generating module 16, and uses an isolation power supply to isolate the input and output of the water negative ion generating module 16, effectively isolating the static electricity, interference signals, and pulses generated by the negative ion generator. This protects the front-end control circuit from the effects of static electricity, crosstalk, and radiation interference from the back-end. Finally, the static charge in the static charge suppression and elimination network absorption circuit is discharged to the ground, eliminating the static charge of the water negative ion generating module 16, thus effectively suppressing or eliminating the static electricity generated by the water negative ion health care machine.

[0041] In one embodiment, such as Figure 2 As shown, the water negative ion generating module 16 includes a π-type filter 161, an isolation power supply U6, a static charge suppression and elimination network 163, a negative ion generator U2, an intermediate control circuit 165, and a conductor structure U3. The input terminal of the π-type filter 161 is connected to the power supply module 11. The output terminal of the π-type filter 161 is connected to the input terminals of the static charge suppression and elimination network 163 and the intermediate control circuit 165 via the isolation power supply U6. The output terminal of the static charge suppression and elimination network 163 is connected to the power supply terminal of the negative ion generator U2. The output terminal of the intermediate control circuit 165 is connected to the control terminal of the negative ion generator U2, and the control signal input terminal of the intermediate control circuit 165 is connected to the main control board 12. The π-type filter 161 is used to filter out residual fluctuation interference from the power supply voltage output by the power supply module 11, while isolating the pulsation, backflow interference, and static charge generated by the negative ion generator U2. The isolation power supply U6 is used for input and output isolation, and the static charge suppression and elimination network 163 is used to release the reverse electromotive force of the negative ion generator U2 and eliminate static charge in the circuit. The intermediate control circuit 165 is used to control the working state of the negative ion generator U2 according to the control signal output by the main control board 12. The conductor structure U3 is connected to the working chamber of the negative ion generator U2 and is used to absorb the static charge in the working chamber.

[0042] It is understood that the negative ion generator U2 is an existing negative ion generator U2 in this field, which is used to generate negative ions on demand under the control of the main control board. The conductor structure U3 is connected to the working chamber of the negative ion generator U2 and is used to absorb excess and residual useless static charge and return it to the negative ion generator U2 and the ground terminal. The isolation power supply U6 is used for input and output isolation, which can effectively isolate the static electricity, interference signals and pulses generated by the negative ion generator U2, so that the front-end control circuit is protected from the influence of static electricity, crosstalk and radiation interference from the back-end. The intermediate control circuit 165 is used to receive the control signal of the negative ion generator U2 output by the main control board 12 and convert it into a corresponding electrical signal to control the operation of the negative ion generator U2.

[0043] In one embodiment, such as Figure 3 As shown, the aforementioned negative ion generating module 16 also includes a power supply terminal P3, a voltage and current sensitive component F1, and a Zener diode D17. The π-type filter 161 includes a capacitor C28, a polarized capacitor C30, an inductor L4, and a capacitor C29. The input terminal of the power supply terminal P3 is connected to the power supply module 11, and the output terminal of the power supply terminal P3 is connected to the input terminal of the voltage and current sensitive component F1. The output terminal of the voltage and current sensitive component F1 is connected to one end of the Zener diode D17, one end of the capacitor C28, the positive terminal of the polarized capacitor C30, and pin 1 of the inductor L4, respectively. One end of the capacitor C28 is also used to output a +12V operating voltage. The other end of the Zener diode D17, the other end of the capacitor C28, the negative terminal of the polarized capacitor C30, and pin 2 of the inductor L4 are all grounded. Pin 3 of inductor L4 is connected to one end of capacitor C29 and the first input terminal of isolation power supply U6, and pin 4 of inductor L4 is connected to the other end of capacitor C29 and the second input terminal of isolation power supply U6.

[0044] It is understandable that the +12V (operating voltage) power supply terminal (i.e., pin 1 of inductor L4) simultaneously supplies power to other modules in the system (such as the front-end control circuit). Power supply terminal P3 is the power input interface; its Pin#4 (i.e., pin 4) is the positive terminal for 24V DC power input, its Pin#5 (i.e., pin 5) is the negative terminal for 24V DC input, and Pin#3 (i.e., pin 3) is used for grounding. Voltage and current sensitive component F1 is used to protect against current surges and overcurrent from the power supply module or operating circuit. It automatically cuts off the input when the instantaneous energy is too high and recovers itself after a certain period. Component F1 is, for example, but not limited to, a fuse, a resettable fuse, a varistor, or a transient voltage suppressor diode (TVS). Zener diode D17 is used to absorb mains voltage surges, smoothing and stabilizing the operating voltage of subsequent circuits, and can clip voltage peaks exceeding the 12V specification.

[0045] Capacitor C28 and polarized capacitor C30, together with inductor L4 and capacitor C29, form a π-type filter 161 to further filter out residual voltage fluctuation interference. At the same time, it further isolates the +12V working circuit from the pulsation, backflow interference and static charge generated by the negative ion generator U2 to avoid mutual interference between circuits.

[0046] In one embodiment, such as Figure 3 As shown, the electrostatic charge suppression and elimination network 163 includes diodes D18, D13, and D14, an ESD suppressor D11, capacitors C25, C26, and C27, and the intermediate control circuit 165 includes a photoelectric converter U7, a light-emitting diode LED2, a resistor R61, a resistor R62, a capacitor C34, and a field-effect transistor Q4. Capacitor C26 is connected between the first and second output terminals of the isolation power supply U6. One end of capacitor C25 is connected to the first output terminal of the isolation power supply U6, the positive terminal of LED2, the negative terminal of diode D18, the first input terminal of ESD suppressor D11, and the power supply input terminal of negative ion generator U2. One end of capacitor C25 is also used to output 12V operating power. The other end of capacitor C25 is connected to one end of capacitor C27 and grounded. The other end of capacitor C27 is connected to the second output terminal of isolation power supply U6 and grounded. The second input terminal of ESD suppressor D11 is connected to the control terminal of negative ion generator U2 and the positive terminal of diode D18. The output terminal of ESD suppressor D11 is grounded. The positive terminal of diode D13 is grounded. The negative terminal of diode D13 is connected to the positive terminal of diode D14. The negative terminal of diode D14 is connected to the power supply output terminal of negative ion generator U2 and grounded. The negative terminal of LED2 is connected to the collector of photoelectric converter U7. The two input pins of photoelectric converter U7 are connected to the main control board 12. The emitter of photoelectric converter U7 is connected to one end of resistor R61 and one end of resistor R62. The other end of resistor R61 is connected to one end of capacitor C34 and the gate of field-effect transistor Q4. The other end of resistor R62, the other end of capacitor C34, and the source of field-effect transistor Q4 are all grounded. The drain of field-effect transistor Q4 is connected to the control terminal of negative ion generator U2.

[0047] It can be understood that the negative ion generator U2 can be used to generate a high voltage of -3.6KVdc and above and release negative ions into the space through the release device. Furthermore, the negative ions are confined in the space within the working chamber of the negative ion generator U2 (i.e., the water negative ion working area), and then combine with the water mist in the working chamber to form water negative oxygen ion clusters. The negative ion generator U2 is controlled by the signal input by the photoelectric converter U7 to manage and control the release and elimination of ions.

[0048] The photoelectric converter U7 is a device unit that converts light signals into electrical signals. Its pins 1 and 2 are the input pins for control signals A and B, respectively. Control signals A and B are converted into electrical signals inside the photoelectric converter U7. The electrical signal execution processing circuit consists of light-emitting diode LED2, resistor R61, resistor R62, capacitor C34, and field-effect transistor Q4, which is used to control and indicate the status of negative ion generator U2.

[0049] Even after controlled shutdown, the static charge suppression and elimination network 163's diode D18 can still release the reverse electromotive force of the negative ion generator U2; capacitors C25, C26, and C27 are used to smooth and output noise interference signal components, and further discharge the static charge absorbed by themselves to the ground. Through the close cooperation of the above electronic components, crosstalk of static charge is effectively isolated, and static charge is eliminated in this part of the circuit, achieving the effect of protecting itself and the system from electrostatic damage and eliminating static charge in the water negative ion working area.

[0050] In one embodiment, such as Figure 3 As shown, the water negative ion generating module 16 also includes a resistor R14 and a capacitor C7. The resistor R14 and the capacitor C7 are connected in parallel. One end of the resistor R14 is connected to the ground terminal of the power supply terminal P3, and the other end of the resistor R14 is connected to the negative terminal of the polarized capacitor C30.

[0051] Understandably, a 1-megohm resistor R14 can be connected in parallel with a 1-nanofa / 500V+ capacitor C7 to filter out residual interference and attracted static charge in the circuit.

[0052] In one embodiment, diode D18 is also connected in parallel with a megaohm resistor. Furthermore, diode D18 can also be connected in parallel with a 1Mohm resistor to enhance its reverse electromotive force release effect.

[0053] In one embodiment, such as Figure 3 As shown, the water negative ion generating module 16 also includes a high-voltage high-resistance resistor R66, which is used to ground the vaporized water storage tank WH inside the working chamber of the negative ion generator U2.

[0054] Understandable. Figure 3 WH is the vaporized water storage tank connected to the working chamber of the negative ion generator U2, and is grounded through a high-voltage, high-resistance resistor R66 to prevent the vaporized water storage tank WH from being affected by voltage fluctuations within the working chamber. The high-voltage, high-resistance resistor R66 can be a 2 megohm resistor with a maximum withstand voltage of 5kV to achieve optimal protection. Furthermore, the volume resistance of the conductor component U3 can be 500 ohms + / -25% to achieve optimal absorption of unwanted static charge.

[0055] In one embodiment, such as Figure 4 As shown, the conveyor fan 15 includes a DC fan 151, a primary filter circuit 153, a drive circuit 155, a speed control circuit 157, a secondary filter circuit 159, and an electrostatic discharge network 158. The input terminal of the primary filter circuit 153 is connected to the power supply module 11, and the output terminal of the primary filter circuit 153 is connected to the input terminal of the drive circuit 155. The control terminal of the drive circuit 155 is connected to the main control board 12.

The output terminal of the speed control circuit 157 is connected to the input terminal of the secondary filter circuit 159, and the control terminal of the speed control circuit 157 is connected to the main control board 12. The output terminal of the secondary filter circuit 159 is connected to the fan signal line of the DC fan 151. The power supply terminal of the DC fan 151 is connected to the power supply module 11 and the electrostatic discharge network 158, respectively.

[0056] The first-stage filter circuit 153 is used to filter out power supply noise and transient fluctuations. The drive circuit 155 is used to enable the drive of the fan 15. The speed control circuit 157 is used to control the speed of the DC fan 151 in response to the speed control signal of the main control board 12 and to isolate the input and output through optocoupler. The second-stage filter circuit 159 is used to filter out residual noise of the fan signal and eliminate static electricity. The static electricity elimination processing network 158 is used to eliminate the static electricity of the entire fan 15.

[0057] It is understood that this embodiment also improves the design of the control circuit of the conveyor fan 15, mainly to provide a stable constant voltage and constant current control signal to the DC fan 151 of the conveyor fan 15. The control circuit is a constant voltage and constant current circuit, independent of the power supply voltage and unaffected by power supply voltage changes. The entire control circuit adopts a wide voltage input, including a fan power supply from 8V to 24V and a gate power supply VG, which together serve as the power input for the DC fan 151 and the control circuit. A single power supply powers the DC fan 151 while simultaneously providing the execution signal drive source, resulting in low cost and no need for additional driver chips, significantly reducing design complexity. To further reduce power consumption and control management complexity, the enable (EN) pin is controlled by the main control board 12. When the EN pin is low, it enables the control circuit of the conveyor fan 15 to perform existing circuit signal processing and control output. The drive circuit 155 is used to connect the speed control circuit 157 to the operating voltage after the first-stage filter circuit 153 filters out power supply noise and transient fluctuations when the EN pin is enabled. The first-stage filter circuit 153 can adopt a capacitive reactance circuit filtering design structure. The speed control circuit 157 is connected to the speed control signals Vdd and FANPWM input from the main control board 12 to the transmission fan 15. The speed control signal Vdd is used as the operating power of the speed control circuit 157, and the speed control signal FANPWM is a PWM encoded speed control signal used to control the rotation speed of the DC fan 151. The speed control signal FANPWM is transmitted through photoelectric conversion to achieve electrical isolation between its input and output.

[0058] The secondary filter circuit 159 is used to filter out residual noise and eliminate static electricity from the fan, thus protecting the fan signal (i.e., the speed control signal FANPWM flowing through the speed control circuit 157). The secondary filter circuit 159 can adopt a capacitive reactance circuit filtering design structure. The static electricity elimination processing network 158 can use resistors and capacitors to eliminate static electricity from the entire transmission fan 15. Through the drive circuit 155 and the speed control circuit 157, the drive control and the speed control command execution of the DC fan 151 are isolated, with no direct connection and no common ground, achieving the effect of constant voltage and constant current with static electricity elimination capability.

The negative terminal of polarized capacitor C8, the other end of capacitor C11, and the power supply output terminal of DC fan 151 are all connected to the gate power supply VG of power module 11. The other ends of Zener diode D12 and capacitor C11 are grounded. The negative terminal of diode D2 is connected to one end of resistor R10 and the source of transistor Q2. The other end of resistor R10 is connected to the gate of transistor Q2 and the source of transistor Q3. The drain of transistor Q2 is connected to the gate of transistor Q3 and the other end of resistor R13. One end of resistor R13 is used to connect to the enable signal output by main control board 12. The drain of transistor Q3 is connected to the negative terminal of Zener diode D5, the positive terminal of polarized capacitor C13, the negative terminal of diode D6, and the collector of optocoupler chip U5, respectively. The positive terminal of Zener diode D5 is connected to the negative terminal of polarized capacitor C13 and grounded.

[0061] The anode of optocoupler chip U5 is connected to one end of resistor R19 and one end of resistor R21. The cathode of optocoupler chip U5 is connected to the other end of resistor R21 and the drain of transistor Q1. The other end of resistor R19 is used to connect to the speed control signal Vdd output by the main control board 12. The emitter of optocoupler chip U5 is connected to one end of resistor R26, one end of capacitor C16, the negative terminal of Zener diode D10, the positive terminal of diode D6, and one end of resistor R20. The other ends of resistor R26, capacitor C16, Zener diode D10, and capacitor C18 are grounded. The other end of resistor R20 is connected to the fan signal line of DC fan 151 and one end of capacitor C18. The gate of transistor Q1 is connected to one end of resistor R27 and one end of resistor R28. The source of transistor Q1 is connected to the other end of resistor R28 and grounded. The other end of resistor R27 is used to connect to the speed control signal FANPWM output by the main control board 12. The second input terminal of voltage regulator D8 is connected to the power supply output terminal of DC fan 151 and the gate power supply VG respectively. The output terminal of voltage regulator D8 is grounded. Capacitor C14 and resistor R18 are connected in parallel. One end of resistor R18 is connected to the output terminal of voltage regulator D8, and the other end of resistor R18 is grounded.

[0062] It can be understood that SK1 is the fan interface for the DC fan 151, used to directly connect to the power supply terminal of the DC fan 151, including the fan signal line (such as terminal 1 of SK1), the power input terminal (such as terminal 2 of SK1), and the power output terminal (such as terminal 3 of SK1). Polarized capacitor C8, capacitor C11, diode D2, and Zener diode D12 form a first-stage filter circuit 153, used to filter out noise and transient fluctuations from the connected power grid, providing a stable operating environment for subsequent circuits and primary protection against static electricity. Resistors R10 and R13, transistors Q2 and Q3, Zener diode D5, and polarized capacitor C13 form a drive circuit 155, used to provide a constant current and constant voltage source and enable drive. Vdd and FANPWM serve as the speed control signals transmitted from the main control board 12 to the fan 15. When the speed control signal Vdd is input, resistors R19 and R21 provide voltage and current limiting and false trigger protection for the optocoupler chip U5. The speed control signal FANPWM reaches the transistor Q1 via resistor R27 and drives the optocoupler chip U5. The speed control signal FANPWM is transferred through optocoupler and its input and output are electrically isolated. Resistor R28 provides assistance and noise immunity for the transistor Q1 to process signals more efficiently. After the speed control signal FANPWM is received and transferred by the optocoupler chip U5, it is connected to the fan interface SK1 via resistor R20 to connect to the fan signal line of the DC fan 151. Resistor R26 and capacitor C16 serve as auxiliary circuits to adjust the optimal values ​​according to the fan parameters.
