[0026] 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 end of the operational amplifier 41 is connected to the output end of the microcontroller 32 to receive the frequency control signal; the output end of the operational amplifier 41 is connected to the input end of the power amplifier 42 to amplify the pulse signal according to the received frequency control signal and transmit it to the power amplifier 42 for power amplification.

[0027] In one embodiment, the digital signal processing unit 500 includes a control chip 51 and a filter 52. The input end of the control chip 51 is electrically connected to the feedback signal output end of the power amplifier 42, and the feedback signal is digitally processed and encoded.

[0028] 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.

[0030] In one embodiment, the environmental sensor 31 includes an electrostatic field sensor 311 and a humidity sensor 312.

In other embodiments, the environmental sensor 31 may only include the electrostatic field sensor 311.

[0031] In one embodiment, a plurality of static elimination needles 23 are provided on the pulse bar, and the static elimination needles 23 are connected in series through the conductive strip 700, and the output end of the double closed-loop pulse amplification unit 400 is electrically connected to the static elimination needle 23 through the conductive strip 700. That is, the pulse generator 800 can provide energy to the plurality of static elimination needles 23 at the same time to expand the static elimination range of the pulse bar. In other embodiments, one pulse generator 800 may be provided corresponding to one static elimination needle 23.

[0032] 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 the 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 electricity 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 electricity 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 electricity 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 from the air nozzle 211, so as to increase the air flow ejected by the nozzle 200 without increasing energy consumption loss, and form an outwardly diffusing air halo, reduce the adsorption of dust particles at the needle tip, and extend the service life of the nozzle 200. Among them, the pulse generator 800 outputs positive and negative polarity pulses alternately to the static elimination needle 23, so that in the positive pulse stage, the tip of the static elimination needle 23 carries positive high voltage, ionizing the air to generate positive ions, and in the negative pulse stage, the tip of the static elimination needle 23 carries negative high voltage, ionizing the air to generate negative ions. Through high-speed switching at the microsecond level (such as hundreds to thousands of times per second), it is manifested macroscopically that positive and negative ions exist simultaneously near the tip of the static elimination needle 23 (that is, at the air nozzle 211). After the airflow is blown out from the air nozzle 211, it carries positive and negative ions to eliminate static electricity in the environment. The increase in the amount of airflow ejected by the nozzle 200 helps to increase the elimination range and elimination speed of static electricity.

[0033] A conical portion 221 and a plurality of stop posts 222 are provided on the fixed seat 22 at one end near the air nozzle 211. An air collection channel 213 connected to the air nozzle 211 is provided on the probe seat 21. The stop posts 222 and the air collection channel 213 are arranged one by one. 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 section of the air collection channel 213 gradually decreases. That is, in the process of the air flow flowing in the probe seat 21 toward the air nozzle 211, it is necessary 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 reduced 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 contact 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.

[0034] 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, avoidance holes 13 are provided on the clamping protrusion 12 at intervals, a probe seat 21 is provided on 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 provided correspondingly, and 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 clamping protrusion 12 is provided on the abutment block 14, and the abutment block 14 can abut against the mounting protrusion 214. The number of the abutment blocks 14 corresponds to the number of the avoidance openings 13. When the probe seat 21 rotates to a preset position in the through hole 11, the abutment column abuts against the mounting protrusion 214, hindering the trend of the probe seat 21 to continue to rotate, and preventing the probe seat 21 from continuing to rotate and preventing the mounting protrusion 214 from being able to escape from the next avoidance opening 13. In other embodiments, the vent pipe 100 and the probe seat 21 can also be fixed by glue.

[0035] In one embodiment, the probe seat 21 is provided with a clamping groove 215 relative to the clamping protrusion 12, and the air hole 218 is provided at the bottom wall of the clamping groove 215. A first air gap 216 is provided between the end surface of the clamping protrusion 12 close to the probe seat 21 and the bottom wall of the clamping groove 215, and a second air gap 217 is provided between the upper end surface of the clamping protrusion 12 and the groove side wall of the clamping groove 215 close to 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 seat 21, and the sealing ring 24 is located on the side of the clamping protrusion 12 close to the air nozzle 211. The airflow enters the second gap through the avoidance port 13 in the vent pipe 100, then enters the first gap, and then enters between the probe seat 21 and the fixing seat 22 through the air hole 218, so as to prepare to enter the air collection channel 213.
