The output end of the dynamic voltage regulation module 61 supplies power to the frequency control unit 300, the dual closed-loop pulse amplification unit 400 and the digital signal processing unit 500 respectively, and can dynamically adjust the output voltage.

[0052] The technical solution of the present invention achieves adaptive adjustment for varying static electricity intensities and ambient humidity to optimize static elimination by collecting environmental data in real time and calculating the optimal pulse frequency based on the current environment. The digital signal processing unit 500 performs high-speed digital sampling and processing on the pulse signal, enhancing the signal's anti-interference capability. The adaptive power management unit 600 automatically adjusts the output voltage based on load changes, ensuring stable power supply to the device under different operating conditions. Specifically, the voltage supplied to the dual-closed-loop pulse amplification unit 400 is adjusted based on the varying intensities of the pulse signal output by the dual-closed-loop pulse amplification unit 400. Therefore, the technical solution of the present invention provides a pulse generator 800 with high stability, wide adaptability, and strong anti-interference capabilities.

[0053] In one embodiment, the dual closed-loop pulse amplification unit 400 includes an operational amplifier 41, a power amplifier 42, an inner-loop current feedback device 43, and an outer-loop voltage feedback device 44. The input of the operational amplifier 41 is connected to the output of the microcontroller 32 to receive a frequency control signal. The output of the operational amplifier 41 is connected to the input of the power amplifier 42. Based on the received frequency control signal, the operational amplifier 41 amplifies the pulse signal and transmits it to the power amplifier 42 for power amplification. The pulse signal output of the power amplifier 42 is connected to the static elimination needle 23 to transmit the pulse signal to the static elimination needle 23. The operational amplifier 41 amplifies the pulse signal to ensure its accuracy and linearity. The pulse signal is then amplified by the power amplifier 42 to meet the high voltage and high current requirements for static elimination. The inner loop current feedback device 43 is located between the power amplifier 42 and the static elimination needle 23, monitoring the output current of the power amplifier 42 in real time and transmitting the current feedback signal to the feedback signal input terminal of the power amplifier 42 via an electrical connection.

In other embodiments, only the operational amplifier 41 and the power amplifier 42 may be included.

[0054] In one embodiment, the digital signal processing unit 500 includes a control chip 51 and a filter 52. The input of the control chip 51 is electrically connected to the feedback signal output of the power amplifier 42, and the feedback signal is digitized and encoded. The output of the control chip 51 is electrically connected to the input of the filter 52. The filter 52 can filter the feedback signal to form a digital signal, remove high-frequency noise and interference components in the feedback signal, and optimize the quality of the feedback signal. The feedback signal is used to control and optimize the dual closed-loop pulse amplification unit 400 and the microcontroller 32. By analyzing and processing the feedback signal, precise control of the pulse signal can be achieved, improving the stability and reliability of the system. The output of the filter 52 is electrically connected to the dynamic voltage regulation module 61, which can dynamically adjust the output voltage of the dual closed-loop pulse amplification unit 400 based on the digital signal transmitted by the filter 52. Specifically, the data signal processing unit filters and processes the feedback signal and transmits the digital signal to the dynamic voltage regulation module 61. The dynamic voltage regulation module 61 dynamically adjusts the output voltage based on the processed digital signal, thereby affecting the operation of the entire system, including the signal output from the power amplifier 42 to the static elimination needle 23. In other embodiments, the filter 52 may not be included.

[0055] In one embodiment, the adaptive power management unit 600 also includes an energy recovery module 62, including a thermocouple array, a boost converter and an energy storage module 621. The thermocouple array is attached to the inner wall of the pulse rod shell to convert waste heat into electrical energy and is electrically connected to the input end of the boost converter; the output end of the boost converter is electrically connected to the energy storage module 621 to convert the voltage output by the thermocouple array and store it in the energy storage module 621. That is, the waste heat generated during the operation of the pulse rod can be converted into electrical energy and stored, thereby improving energy utilization efficiency. Furthermore, the dynamic voltage regulation module 61 includes a DC / DC converter to achieve output voltage regulation. In other embodiments, the energy recovery module 62 may not be provided.

[0056] In one embodiment, the adaptive power management unit 600 further includes a solar charge controller 63 and a solar panel 64. The input of the solar charge controller 63 is electrically connected to the solar panel, and the output of the solar charge controller 63 is electrically connected to the energy storage module 621.

Specifically, the microcontroller 32 calculates the frequency of the pulse signal that the pulse generator 800 should emit based on data such as the humidity and static electricity intensity in the environment. In other embodiments, the environmental sensor 31 may include only the electrostatic field sensor 311.

[0058] In one embodiment, a pulse bar is equipped with multiple static-eliminating pins 23, which are connected in series via a conductive strip 700. The output of the dual-closed-loop pulse amplification unit 400 is electrically connected to the static-eliminating pins 23 via the conductive strip 700. In other words, the pulse generator 800 can simultaneously provide energy to multiple static-eliminating pins 23, thereby expanding the static-eliminating range of the pulse bar. In other embodiments, one pulse generator 800 may be provided for each static-eliminating pin 23.

[0059] The present invention also proposes a pulse rod, which includes a ventilation pipe 100, a nozzle 200 and a pulse generator 800. The specific structure of the pulse generator 800 refers to the above-mentioned embodiment. Since this pulse rod adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one. Among them, the nozzle 200 includes a probe seat 21, a fixing seat 22 and a static elimination needle 23. The probe seat 21 is connected to the ventilation pipe 100, and an air nozzle 211 is provided on the probe seat 21. A cyclone block 212 is arranged circumferentially around the air nozzle 211. The static elimination needle 23 can extend from the ventilation pipe 100 through the air nozzle 211. The fixing seat 22 is clamped in the probe seat 21 and can fix the static elimination needle 23. The probe seat 21 is provided with an air hole 218 on the circumferential side of the ventilation pipe 100. The air flow can enter between the probe seat 21 and the fixing seat 22 from the air hole 218, and then be ejected through the air nozzle 211. The cyclone block 212 can cause the gas near the air nozzle 211 to be drawn into the air flow ejected by the air nozzle 211, so as to increase the air flow ejected by the nozzle 200 without increasing energy loss, and form an outward-diffusing air halo, reduce the adsorption of dust particles at the needle tip, and extend the service life of the nozzle 200. The pulse generator 800 alternately outputs positive and negative polarity pulses to the ionizing needles 23. During the positive pulse phase, the needle tips of the ionizing needles 23 carry a positive high voltage, ionizing the air to produce positive ions. During the negative pulse phase, the needle tips of the ionizing needles 23 carry a negative high voltage, ionizing the air to produce negative ions. This high-speed switching, occurring at microsecond levels (e.g., hundreds to thousands of times per second), manifests macroscopically as the simultaneous presence of positive and negative ions near the needle tips of the ionizing needles 23 (i.e., at the nozzle 211). The airflow from the nozzle 211 carries both positive and negative ions, eliminating static electricity in the environment. The increased airflow from the nozzle 200 helps improve the range and speed of static elimination.

[0060] The fixed base 22 is provided with a tapered portion 221 at one end near the air nozzle 211, and a plurality of stop posts 222. The probe base 21 is provided with an air collection channel 213 connected to the air nozzle 211. The stop posts 222 are arranged in a one-to-one correspondence with the air collection channel 213. The stop posts 222 block part of the structure of the air inlet end of the air collection channel 213. In the direction away from the vent pipe 100, the area of ​​the plane cross section of the air collection channel 213 gradually decreases. That is, when the air flow flows in the probe base 21 toward the air nozzle 211, it needs to first flow through the gap between the air collection channel 213 and the stop posts 222, and then flow through the gap between the air nozzle 211 and the static elimination needle 23 after passing through the gradually shrinking air collection channel 213. At this time, the air flow is affected by the Laval nozzle effect, and the air flow speed gradually increases. After the air flow flows out of the air nozzle 211, the air flow speed can reach the maximum speed, so as to reduce the time interval when the positive and negative ions come into contact with the target object to be eliminated. Furthermore, the static elimination needle 23 is arranged in a cone shape, and its shape and structure conform to fluid mechanics and will not hinder the entrainment of surrounding air.

[0061] In one embodiment, a through hole 11 is provided on the ventilation pipe 100, a clamping protrusion 12 is provided on the inner ring of the through hole 11, and avoidance holes 13 are provided at intervals on the clamping protrusion 12. The probe seat 21 is provided in the through hole 11, and a mounting protrusion 214 is provided on the outer wall of the probe seat 21. The avoidance hole 13 and the mounting protrusion 214 are arranged correspondingly. The mounting protrusion 214 can pass through the avoidance hole 13, and then the probe seat 21 is rotated so that the mounting protrusion 214 can abut against the side of the clamping protrusion 12 away from the air nozzle 211 to fix the probe seat 21 to the ventilation pipe 100. Furthermore, the lower end surface of the engaging protrusion 12 is provided on an abutment block 14, which can abut against the mounting protrusion 214. The number of abutment blocks 14 corresponds to the number of avoidance openings 13. When the probe base 21 rotates to a preset position in the through hole 11, the abutment column abuts against the mounting protrusion 214, hindering the continued rotation of the probe base 21 and preventing the mounting protrusion 214 from being able to escape from the next avoidance opening 13 due to continued rotation. In other embodiments, the vent tube 100 and the probe base 21 can also be fixed by glue.

[0062] In one embodiment, the probe base 21 is provided with a snap-fit ​​groove 215 relative to the snap-fit ​​protrusion 12. An air hole 218 is provided on the bottom wall of the snap-fit ​​groove 215. A first air gap 216 is defined between the end surface of the snap-fit ​​protrusion 12 near the probe base 21 and the bottom wall of the snap-fit ​​groove 215. A second air gap 217 is defined between the upper end surface of the snap-fit ​​protrusion 12 and the side wall of the snap-fit ​​groove 215 near the air nozzle 211. A sealing ring 24 is sandwiched between the hole wall of the through hole 11 and the outer wall of the probe base 21. The sealing ring 24 is located on the side of the snap-fit ​​protrusion 12 near the air nozzle 211. Airflow in the vent pipe 100 passes through the avoidance opening 13 into the second gap, then into the first gap, and then through the air hole 218 into the space between the probe base 21 and the fixing base 22, preparing to enter the air collection channel 213.
