[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please refer to Figure 1-6 ;

[0028] An intelligent DC digital display ion fan includes an outer frame 1. A fan mesh device 2 is provided on one side of the outer frame 1. The outer frame 1 and the fan mesh device 2 are detachably connected. The fan mesh device 2 is connected to the outer frame 1 by four protruding fixed ends, which are fitted onto bolts. An ion fan 3 and discharge needles 4 are provided on the other side of the outer frame 1. In this embodiment, there are 6 discharge needles 4. The 6 discharge needles 4 are detachably connected to the outer frame 1. The ion fan 3 is located between the discharge needles 4 and the fan mesh device 2. Ions are ionized from the discharge needles 4 and pass sequentially through the ion fan 3 and the fan mesh device 2.

[0029] In the intelligent DC digital display ion fan, the movement of ions begins with the corona discharge generated by the discharge needle 4 under the action of DC high voltage, ionizing the surrounding air to generate positive and negative ions. The ions are then propelled by the airflow generated by the ion fan 3, passing through the ion fan 3 and the fan mesh device 2 in sequence, and blown towards the target area to neutralize the static electricity on the object surface. In traditional DC ion fans, positive and negative ions are often not fully mixed, resulting in uneven ion distribution, poor static electricity elimination effect, and the possibility of introducing residual charge on the target surface due to the imbalance of positive and negative ions. This intelligent ion fan optimizes the sequential design of the ion fan 3 and the discharge needle 4 to promote the full mixing of positive and negative ions in the airflow, making the ion distribution more uniform and significantly improving the static electricity neutralization efficiency. It is particularly suitable for high-precision scenarios such as semiconductor manufacturing, ensuring a more stable and reliable static electricity removal effect.

[0030] Furthermore, the outer frame 1 is equipped with a main board 5, which includes a balance adjuster 6, an MCU chip, and a digital-to-analog converter. The main board 5 is electrically connected to the balance adjuster 6, the MCU chip, and the digital-to-analog converter. The fan mesh device 2 includes two detection meshes 21, which are installed on both sides of the front sidewall of the outer frame 1. The detection meshes 21 are electrically connected to the main board 5. The detection meshes 21 are used to detect real-time ion signals and transmit them to the digital-to-analog converter via the main board 5. The digital-to-analog converter converts the real-time ion signals into digital signals and transmits the digital signals to the MCU chip via the main board 5. The MCU chip controls the balance adjuster 6 to adjust the ion balance according to the digital signals.

[0031] Specifically, the discharge needle 4 generates corona discharge under DC high voltage, ionizing the air to generate positive and negative ions. These ions are propelled by the airflow of the ion fan 3, passing through the fan mesh device 2 and blown towards the target area. Two detection meshes 21 installed on both sides of the front wall of the outer frame 1 in the fan mesh device 2 capture ion signals in real time, detecting the distribution and balance of positive and negative ions. The detection meshes 21 transmit the collected ion signals to the main board 5. The analog-to-digital converter on the main board 5 converts these analog signals into digital signals and transmits them to the MCU chip. The MCU chip analyzes the ion balance state based on the received digital signals and controls the ion distribution. The balance adjuster 6 dynamically adjusts the output of the discharge needle 4 to optimize ion balance and ensure electrostatic neutralization. Compared with the traditional manual balance adjustment method, this design, through the collaborative work of the detection network 21, the digital-to-analog converter unit, and the MCU chip, can monitor ion signals in real time and respond quickly to automatically adjust the ion balance. In addition, manual adjustment relies on the operator's experience, is slow and has limited accuracy, and is difficult to cope with dynamically changing electrostatic environments. The MCU chip automatically controls the balance adjuster 6 according to digital signals, eliminating human error and ensuring consistent ion balance in each operation without manual intervention.

[0032] In this embodiment, the outer frame 1 is provided with an observation window 7, the main board 5 is electrically connected to a display screen 8, the display screen 8 is connected to the side wall of the outer frame 1, and the side wall of the outer frame 1 is provided with control buttons 10, the number of control buttons 10 is 3; the operator can observe the ion balance displayed on the display screen 8 in real time through the observation window 7, and the operator can adjust the ion fan through the control buttons 10.

[0033] In this embodiment, the discharge needle 4 is detachably connected to the outer frame 1. The discharge needle 4 is provided with a snap-fit ​​post 11. The snap-fit ​​post 11 has a through groove 12. The discharge needle 4 is sleeved on the needle cylinder 13. The needle cylinder 13 passes through the through groove 12 and is inserted into the snap-fit ​​post 11. The outer frame 1 is provided with a notch 14. The snap-fit ​​post 11 is snapped into the notch 14.

[0034] Because the discharge needle 4 and the outer frame 1 are detachably connected, the user can easily disassemble the discharge needle 4 for cleaning. The specific operation is as follows: first, loosen the locking post 11 through the notch 14 on the outer frame 1, then pull the discharge needle 4 together with the syringe 13 out of the through groove 12 of the locking post 11. After disassembly, the user replaces the discharge needle 4 with a new one and removes the dulled discharge needle 4. After replacement, the discharge needle 4 and the syringe 13 are reinstalled back into the locking post 11 along the original path. Then, the locking post 11 is locked to the notch 14. The whole process does not require complicated tools or professional skills and is simple and efficient.

[0035] In this embodiment, the outer frame 1 is provided with a rotating device, which can adjust the orientation of the detection net 21 according to the environment.

[0036] Specifically, the rotating device includes a mounting bracket 15 and a knob 16. Rotation holes 17 are provided on both sides of the outer frame 1. There are two knobs 16. Both knobs 16 pass through the clearance hole 18 of the mounting bracket 15 and rotate through the hole wall of the rotation hole 17 of the outer frame 1. The knobs 16 can be used to fix the relative positions of the outer frame 1 and the mounting bracket 15.

[0037] More specifically, during assembly, the outer frame 1 is placed between the mounting brackets 15, ensuring that the clearance hole 18 is aligned with the rotation hole 17. Then, the knob 16 is tightened to ensure that the mounting bracket 15 and the outer frame 1 remain fixed. If loosening is required, the knob 16 is loosened first, and then the position of the outer frame 1 is adjusted. After adjusting the position of the outer frame 1, the knob 16 is tightened again to complete the fixation of the outer frame 1 and the mounting bracket 15, thereby facilitating the rotation of the position of the outer frame 1, thereby facilitating the adjustment of the orientation of the detection mesh 21, and thus adjusting the orientation of the ion wind.

[0038] Furthermore, adjustable fixing plates 19 are fixedly installed on both sides of the outer frame 1, and adjustable fixing plates 20 are fixedly installed on one side of the mounting bracket 15. Both adjustable fixing plates 19 and 20 are located between the outer frame 1 and the mounting bracket 15. The knob 16 passes through the adjustable fixing plates 19 and 20. Both adjustable fixing plates 19 and 20 are provided with toothed surfaces 201, and the adjustable fixing plates 19 and 20 mesh through the toothed surfaces 201.

[0039] During assembly, place the outer frame 1 between the mounting brackets 15, ensuring that the clearance hole 18 is aligned with the rotation hole 17. The knob 16 passes through the clearance hole 18, the adjustable fixing plate 19, and the adjustable fixing plate 20 of the mounting bracket 15 and is threaded into the rotation hole 17 of the outer frame 1. The toothed surfaces 201 of the adjustable fixing plate 19 and the adjustable fixing plate 20 engage with each other, providing precise angle control. In use, the user first loosens the knob 16 to release the engagement of the toothed surfaces 201, and then adjusts the position of the outer frame 1 in increments of 10 degrees, within a range of 70 degrees forward and backward, thereby changing the orientation of the detection mesh 21 and the ion air outlet. After adjusting to the target angle, tighten the knob 16 to re-engage the toothed surfaces 201 of the adjustable fixing plate 19 and the adjustable fixing plate 20, fixing the relative position of the outer frame 1 and the mounting bracket 15, ensuring the stable orientation of the detection mesh 21 and the air outlet.

[0040] The toothed surface 201 of the adjustable fixing plate 19 and the adjustable fixing plate 20 supports precise adjustment in 10-degree increments, allowing arbitrary adjustment of the detection net 21 and the air outlet orientation within a range of 70 degrees in front and behind. It can optimize the delivery direction of the ion wind and the accuracy of signal acquisition according to the electrostatic distribution requirements of the usage environment (such as semiconductor manufacturing, clean room, etc.).

[0041] In this embodiment, an antenna 22, a power socket 23, a power switch 24 and a grounding port are provided on one side of the outer frame 1. The antenna 22, the power switch 24 and the grounding port are all electrically connected to the motherboard 5, and the power socket 23 is electrically connected to the power supply.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
