Technical Field

[0001] The present application relates to the technical field of ion elimination equipment, and in particular to an ion emitter and air ion elimination equipment. Background Art

[0002] Currently, many industries are plagued by problems caused by static electricity. For example, in the electronics industry, integrated circuits and liquid crystal displays may be damaged by electrostatic discharge, and static electricity can adsorb particles and damage cleanliness, thereby affecting product quality.

[0003] In order to eliminate the effects of static electricity, existing treatment methods include using ion fans to eliminate static electricity. Ion fans neutralize the charges on objects by generating a large amount of airflow with positive and negative charges, thereby achieving the purpose of eliminating static electricity.

[0004] However, since the current ion blower is designed to integrate the ionization device and the blower, and has a simple structure and appearance design, for example, the ion blowers currently on the market are basically square-shaped desktop, hanging and horizontal machines, and the fan blades use axial flow fans, which take up a lot of space when used on site and are inconvenient to install. In addition, it is difficult to meet the usage requirements under certain conditions, such as the need for ion wind coverage at a special angle, small spaces, and frequently changing spaces (such as automobile assembly lines, to eliminate static electricity in the car body). Utility Model Content

[0005] In order to enable the air ion elimination device to adapt to more usage requirements and improve applicability, the present application provides an ion emitter and an air ion elimination device.

[0011] A connecting wire, one end of which is electrically connected to the FPC board, and the other end of which extends outside the housing.

[0012] By adopting the above technical solution, the ion emitter can be installed on the air outlet in a detachable manner, and the air outlet can be a fan of different shapes and sizes, or an air outlet duct of different sizes, etc. The ion emitter can be used in conjunction with different air outlets in different usage scenarios to improve the applicability of the air ion elimination equipment, and the connecting wire can be used to connect to the circuit of the control system, and the connecting wire can be used to power the FPC board and / or provide communication signals to control the FPC board, thereby adjusting the discharge effect of the discharge component.

[0020] and / or, the surface resistivity of the protective cover is higher than 1×10e5Ω / sq;

[0021] And / or, the protective cover is trumpet-shaped and expands in a direction away from the FPC board.

[0022] By adopting the above technical solution, the provision of a protective cover can reduce the contact between the discharge component and the human body, thereby reducing the danger; the distance between the end of the protective cover away from the FPC board and the end of the discharge component is greater than 2 mm, so that the discharge component is not exposed, preventing human fingers from touching the discharge component, and can better release ions; the surface resistivity of the protective cover is higher than 1×10e5Ω / sq, which can further reduce the possibility of electric shock to the user; the protective cover is trumpet-shaped with the mouth flared away from the FPC board, which can facilitate the release of ions and the installation of the protective cover.

[0027] On the other hand, the present application also discloses an air ion elimination device, which adopts the following technical solution:

[0028] An air ion static elimination device, comprising the ion emitter described in any one of the above, as well as a bias voltage detection device and a host system, wherein the host system is communicatively connected to the ion emitter and the bias voltage detection device;

[0029] The bias voltage detection device is used to detect the bias voltage value of the measured area and feed it back to the host system. The host system controls the discharge component of the ion emitter to release ions based on the obtained bias voltage value.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-4 This application is described in further detail.

[0048] Reference Figure 1 , is an ion blower 7 in the related art. The ion blower 7 has the functions of a conventional blower and can blow air. An ion emitter (not shown in the figure) is provided inside the ion blower 7, and a corresponding control system is provided to control the ion emitter. After the moving wind passes through the ion emitter, it can carry charged ions and act on the designated area to achieve the effect of static neutralization. A voltage detection component is usually provided at the ion wind outlet to detect the bias voltage in the surrounding area and feed it back to the control system to adjust the ion release type and ion release amount of the ion emitter 1. However, since the ion blower 7 and the corresponding ion emitter are an integrated structure, the usage scenario is affected by the specific structure and size of the ion blower 7, and its applicability is poor. In addition, the voltage detection component of the ion blower 7 is far away from the area where the ion wind acts, which further affects the detection accuracy and neutralization accuracy. There are also further requirements for the placement of the ion blower 7, which also leads to poor applicability.

[0049] The present application discloses an air ion elimination device, referring to Figure 2 An air ion elimination device includes a host system 2, a bias voltage detection device 3 and an ion emitter 1, and the host system 2 and the bias voltage detection device 3, as well as the host system 2 and the ion emitter 1 are communicatively connected.

[0050] Bias voltage is also called ion balance. It determines the risk that the air ion static elimination equipment may cause the treated objects to carry static electricity. It is a very important control indicator in the electronics industry, especially in the static electricity control of semiconductors. The bias voltage detection device 3 is placed in the ion wind action area, which can detect the bias voltage condition of the area, that is, the static electricity condition, and transmit the formed electrical signal to the control system 21. The bias voltage detection device 3 is an existing product, mainly including a voltage acquisition module, an instruction receiving module, a control module, and other auxiliary parts, such as a signal amplifier, a signal collector, a signal analysis and processing unit, etc. Because it is an existing product, this application will not go into details. The bias voltage detection device 3 and the control system 21 are connected by a shielded wire 5. While realizing the communication connection, it can also reduce the signal interference between the two and improve the detection accuracy.

[0051] Reference Figure 2 and Figure 3 The ion emitter 1 includes an ion emission module, which includes a housing 11 and an FPC board 12 (flexible printed circuit board) disposed within the housing 11. The FPC board 12 is electrically connected to a discharge element 13 via a connecting wire 6, which is a high-voltage-resistant conductor. One end of the discharge element 13 is located outside the housing 11 and may be a discharge brush or a discharge needle. Specifically, the discharge brush may be made of conductive carbon fiber, while the discharge needle may be made of metal. The principle of ion release by the discharge element 13 is primarily based on electrostatics, electric fields, and ionization phenomena. High AC or DC voltage (AC can be AC ​​or pulses of varying frequencies, and DC can be stable DC or unipolar pulses) is applied to the discharge needle or brush to ionize the surrounding gas and release ions. The specific implementation method is also prior art and will not be described in detail in this application. The FPC board 12 is also connected to another connecting wire 6 extending outside the housing 11. The connecting wire 6 is used to communicate with the host system 2, enabling the host system 2 to control the FPC board 12 and, in turn, the discharge of the discharge element 13.

[0052] In some preferred embodiments of the present application, multiple FPC boards 12 are provided, and multiple discharge elements 13 are provided, divided into positive discharge elements 131 for releasing positive ions, and negative discharge elements 132 for releasing negative ions. One or more negative discharge elements 132 can be connected to one FPC board 12, and one or more positive discharge elements 131 can be connected to another FPC board 12. This allows for independent control of each type of discharge element 13, and also facilitates adjustment of the type and unit amount of ion release by the ion emitter 1. This application uses two FPC boards 12 as an example, with two negative discharge elements 132 on one FPC board 12 and two positive discharge elements 131 on the other FPC board 12. The two FPC boards 12 are arranged in parallel and separated by an insulating spacer 14. The insulating spacer 14 is made of a high-dielectric-strength material, such as polyimide (PI), with an insulation strength greater than the potential difference between the two high-voltage circuits, to reduce mutual influence between the two FPC boards 12.

[0053] Reference Figure 4 , a protective cover 133 is also provided on the outside of the discharge member 13. The protective cover 133 is open at one end away from the FPC board 12, and is in the shape of a trumpet that expands in the direction away from the FPC board 12. The trumpet-shaped protective cover 133 can facilitate the release of ions and the installation of the protective cover 133. The distance from the end of the protective cover 133 away from the FPC board 12 to the end of the discharge member 13 is greater than 2 mm, so that the discharge member 13 will not be exposed, preventing people's fingers from touching the discharge member 13, and can better release ions. The surface resistivity of the protective cover 133 is higher than 1×10e5Ω / sq, which can further reduce the possibility of electric shock to the user. In the present application, the spacing between adjacent discharge members 13 is greater than 15 mm to reduce the mutual interference between the discharge members 13, especially the mutual interference between the positive discharge member 131 and the negative discharge member 132.

[0054] Reference Figure 4 The ion emitter 1 also includes a mounting plate 15 for removably connecting to the air outlet 4, and the housing 11 also includes a fixing plate 111 for removably connecting to the mounting plate 15. The air outlet 4 can be a variety of fans, blowers, or even air ducts of various sizes and shapes, depending on the usage environment and requirements. The removable connection between the ion emitter 1 and the air outlet 4 further enhances the applicability of the air ion static elimination device.

[0055] Specifically, the mounting plate 15 and the fixing plate 111 can be connected magnetically, for example, one includes an iron part and the other includes a magnet, or both include magnets. Since the outer shell of the air outlet 4 is mostly made of iron material, the mounting plate 15 can also be fixed to the air outlet 4 by magnetic attraction. In some other embodiments, the mounting plate 15 and the fixing plate 111 can also be bonded with adhesive, and the mounting plate 15 can also be fixed to the air outlet 4 by adhesive. In some other embodiments, the mounting plate 15 and the fixing plate 111 can be fixed with Velcro, and the mounting plate 15 and the air outlet 4 can be connected by tying, wrapping, clamping, pressing, etc., and the mounting plate 15 is then connected to the fixing plate 111 to achieve the connection between the ion emitter 1 and the air outlet 4. The mounting plate 15, the fixing plate 111, and the insulating isolation plate 14 body are all made of flexible materials, so that the ion emitter 1 can be installed on a curved surface or an irregular surface, further improving the applicability of the air ion static elimination device.

[0056] Reference Figure 2 and Figure 3 The host system 2 includes a control system 21 and a high-voltage module 22. The control system 21 is communicatively connected to the bias voltage detection device 3 and includes a microprocessor 211 and a regulator 212. The high-voltage module 22 includes a positive high-voltage module 221 and a negative high-voltage module 222. The microprocessor 211 is responsible for processing and executing monitoring and control operations, receiving electrical signals from the bias voltage detection device 3, performing calculations and logical processing according to preset parameters and algorithms, and adjusting the output voltage and frequency of the positive high-voltage module 221 and / or the negative high-voltage module 222 through the regulator 212. The output high-voltage frequency can be adjusted by the input voltage and frequency. The high-voltage module 22 with a voltage regulation function is a mature product on the market and will not be discussed in detail in this application. Finally, the positive high-voltage module 221 is connected to the positive discharge element 131 to independently regulate the ion release of the positive discharge element 131, and the negative high-voltage module 222 is connected to the negative discharge element 132 to independently regulate the ion release of the negative discharge element 132.

[0057] The control system 21 gives a reverse adjustment instruction code to the high voltage generation of the high voltage module 22 according to the bias voltage data: if a negative bias voltage is detected, the output voltage of the positive high voltage module 221 is increased or the output voltage of the negative high voltage module 222 is decreased; if a positive bias voltage is detected, the output voltage of the negative high voltage module 222 is increased or the output voltage of the positive high voltage module 221 is decreased.

[0058] The ion emitter module 1 is connected to the high-voltage module 22 via a high-voltage-resistant connecting wire 6. Since DC high-voltage ionization is employed, to avoid the risk of induced charging due to the electrostatic field generated by the high voltage in the connecting wires, the two connecting wires 6 connecting the positive discharge element 131 and the negative discharge element 132 can be twisted pairs. This allows the positive and negative electric fields to cancel each other out, eliminating the risk of a single electrostatic field. Furthermore, to avoid the risk of induced charging due to local electric field imbalance, the connecting wires 6 can be wrapped with electrostatic field shielding material and then grounded.

[0059] The implementation principle of an air ion elimination device in an embodiment of the present application is as follows: since the ion emitter 1 can be connected to various types of air outlets 4, the air outlet 4 can be selected according to the specific use environment, so that the ion emitter 1 can be adaptably installed in different use environments, thereby improving the applicability of the air ion elimination device; the air ion elimination device can detect the bias voltage of the corresponding area through the bias voltage detection device 3, and transmit the detection signal to the control system 21. After the control system 21 analyzes the electrical signal, it sends an instruction to the high-voltage module 22. The high-voltage module 22 can control the discharge of the discharge component 13, thereby adjusting the release type and release amount of ions, and neutralizing the static electricity in the designated action area.

[0060] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
