[0023] According to an embodiment of the present invention, a charge elimination structure suitable for an ion generator has at least one pair of high-voltage discharge terminals, and the charge elimination structure includes a driving portion and a conducting portion, wherein: the driving portion is connected to the conducting portion and is used to drive the conducting portion to perform reciprocating motion; the conducting portion is used to simultaneously contact all high-voltage discharge terminal surfaces during the reciprocating motion so that the electric potential of all high-voltage discharge terminals is the same.

[0024] The specific form of the high-voltage discharge terminal is not limited in this embodiment. Optionally, the high-voltage discharge terminal is a probe-shaped tip, typically comprising a cylindrical body and a tip located on a top surface of the cylinder. In other embodiments of the present application, the high-voltage discharge terminal can also be in the form of a carbon brush formed by a soft-bristle brush.

[0025] In this embodiment, the driving part can be arranged on certain components inside the ion generator, or can be arranged separately inside the ion generator; the conductive part is arranged corresponding to the high-voltage discharge end, and the conductive part is located above the tip of the high-voltage discharge end, and the driving part and the conductive part are relatively fixedly connected, that is, the driving part can drive the conductive part to move along the axial direction of the high-voltage discharge end, so that the conductive part can contact the high-voltage discharge end, thereby neutralizing the charges on the two high-voltage discharge ends or eliminating the charges.

[0026] In this embodiment, the ion generator can be a positive and negative ion generator, a negative ion generator, or a plasma generator. When the ion generator is a positive and negative ion generator or a plasma generator, it can include only one pair of high-voltage discharge terminals, that is, one positive high-voltage discharge terminal and one negative high-voltage discharge terminal, or it can include multiple pairs of high-voltage discharge terminals. In this embodiment, the arrangement of the multiple pairs of high-voltage discharge terminals is not limited. It can be that multiple positive high-voltage discharge terminals are arranged in a row, and multiple negative high-voltage discharge terminals are arranged in a row, and the tips of the two rows of high-voltage discharge terminals are arranged opposite to each other or facing each other. When the ion generator is a negative ion generator, it can also include only one pair of high-voltage discharge terminals, or it can include multiple pairs of high-voltage discharge terminals. In this case, the corresponding pair of high-voltage discharge terminals includes a negative high-voltage discharge terminal and an induction terminal. Among them, the induction terminal is usually a ground terminal. When the conductive part contacts the negative high-voltage discharge terminal and the induction terminal at the same time, the negative charge accumulated on the negative high-voltage discharge terminal is guided to the ground terminal, so that the negative charge accumulated on the negative high-voltage discharge terminal is released and eliminated, thereby avoiding the accumulation of charge.

[0027] When the high-voltage discharge terminals comprise a pair of positive and negative high-voltage discharge terminals, the charge elimination structure of the ion generator according to the embodiment of the invention utilizes a driving unit to drive the conductive unit, enabling the conductive unit to simultaneously contact the pair of positive and negative high-voltage discharge terminals to neutralize and eliminate the positive and negative charges, thereby restoring the voltage difference between the pair of high-voltage discharge terminals. This charge elimination structure for maintaining the ion generator is simple and easy to implement, effectively neutralizing and eliminating the positive and negative charges accumulated on the surfaces of the positive and negative high-voltage discharge terminals, thereby enabling the ion generator to continue operating normally and reducing the attenuation of the ionization effect.

[0028] The charge elimination structure may further include a fixing mechanism for fixedly connecting to the ion generator. The driving unit includes a bracket and an electromagnet. The bracket is fixedly connected to the fixing mechanism. The electromagnet specifically includes an electromagnet base member and an electromagnet movable member. The electromagnet base member is fixedly connected to the bracket so that the electromagnet base member is stationary relative to the ion generator, while the electromagnet movable member can drive the conductive portion to reciprocate in a direction parallel to the high-voltage discharge end, thereby completing the charge elimination process.

[0029] The conductive portion is connected to the electromagnet movable part, thereby moving under the influence of the electromagnet movable part. It also includes a component that performs a conductive function. In this embodiment, the conductive portion can be a metal sheet that is fixedly connected to the electromagnet movable part, so that the metal sheet can reciprocate with the electromagnet movable part. The specific material of the metal sheet is not limited in this embodiment, and can be selected from silver, copper, gold, aluminum, tungsten, nickel, iron, or platinum. Iron or aluminum is more preferred for simplicity of manufacturing and low cost.

[0030] In a first state (i.e., when the electromagnet is not energized), the metal sheet is stationary, located above the high-voltage discharge terminal and at a safe distance (e.g., greater than 5 mm) from the high-voltage discharge terminal. Setting a safe distance prevents the distance between the metal sheet and the high-voltage discharge terminal from being too close, thereby preventing the discharge efficiency of the high-voltage discharge terminal from being reduced. In a second state (i.e., when the electromagnet is energized), the metal sheet reciprocates with the electromagnet's movable part and can simultaneously contact at least one pair of high-voltage discharge terminals during this movement. When contact occurs, the oppositely charged charges on the paired high-voltage discharge terminals are transferred to the metal sheet and then cancel each other out, achieving charge neutralization.

[0031] When the high-voltage discharge terminal includes a positive high-voltage discharge terminal and a negative high-voltage discharge terminal, the metal sheet may have a central interface and at least one pair of through holes, wherein the central interface is located at the center of the metal sheet and is used to securely connect to the bracket. The at least one pair of through holes are symmetrically positioned about the central interface, and the position and size of the at least one pair of through holes match the position and size of the at least one pair of high-voltage discharge terminals. During the reciprocating motion of the metal sheet, the paired through holes are symmetrical about the central interface, ensuring relatively balanced force, thereby preventing the metal sheet from shifting during motion and causing misalignment between the through holes on the metal sheet and the high-voltage discharge terminals.

[0032] To prevent the high-voltage discharge end from stabbing the user, the charge elimination structure can also include a protective cover arranged around the high-voltage discharge end. The protective cover can be a cylinder with a hollow window, which can ensure permeability and allow ions to diffuse smoothly into the environment.

[0033] The charge elimination structure may also include a timer switch module and / or a manual switch module connected to the electromagnet. If the charge elimination structure only includes the timer switch module, the structure can automatically start and stop the cleaning operation on a regular basis, for example, once a day for one minute at a time. If the structure only includes the manual switch module, the structure can flexibly start the cleaning operation manually according to user needs. If the structure includes both the timer switch module and the manual switch module, the structure can achieve dual automatic / manual control.

[0034] The ion generator typically includes a bottom shell, a top cover, and a circuit board. The bottom shell is fixedly connected to the fixing mechanism, and the top cover is fixedly connected to the bottom shell. The bottom shell and top cover, when assembled, form a cavity that accommodates and protects components such as the electromagnet and the fixing mechanism. The circuit board can be located within the bottom shell and electrically connected to the high-voltage discharge terminal and the electromagnet. The aforementioned timer switch module and / or manual switch module of the charge neutralization mechanism can also be located on this circuit board.

[0035] To make those skilled in the art better understand, Figures 2 to 4 Provide specific instructions.

[0036] according to Figures 2 to 4 The ion generator and its charge elimination structure shown in the figure include a pair of high-voltage discharge terminals 11, a bottom shell 16, a top cover 17, and a circuit board 18. The high-voltage discharge terminals 11 are fixed to the bottom shell 16 via a fixing mechanism 15. The driving portion of the charge elimination structure primarily comprises an electromagnet 12 and a bracket 13. The conductive portion of the charge elimination structure primarily comprises a metal sheet 14. The electromagnet 12 specifically comprises an electromagnet base 121 and an electromagnet movable member 122. The electromagnet base 121 is fixedly connected to the bracket 13, thereby ensuring that the electromagnet base 121 and the high-voltage discharge terminal 11 remain stationary relative to each other. The electromagnet movable member 122 is fixedly connected to the metal sheet 14 and can drive the metal sheet 14 to reciprocate in a vertical direction to achieve charge neutralization. The center of the metal sheet 14 has a central interface 141, with a pair of through holes 142 symmetrically disposed on either side of the central interface 141. The central interface 141 is used to securely connect the metal sheet 14 and the electromagnet movable member 122. Specifically, this secure connection can be achieved by engaging a screw and nut. The pair of through-holes 142 are used to pass through the pair of high-voltage discharge terminals 11. The through-holes 142 are aligned with the pair of high-voltage discharge terminals 11, and their diameters are slightly larger than the diameters of the high-voltage discharge terminals 11 to facilitate smooth passage. It should be noted that the "slightly larger" mentioned in this embodiment can be understood as a tolerance, ensuring that the holes in the metal sheet can accommodate the high-voltage discharge terminals while simultaneously ensuring contact between the metal sheet and the high-voltage discharge terminals, thereby providing electrical continuity between the high-voltage discharge terminals connected to the metal sheet.

[0037] In addition, in order to ensure that the conductive portion can fully contact the high-voltage discharge end, the opening of the conductive portion can be made into an oblique angle in this embodiment. Figure 5 As shown, in the cross-sectional view, the surface of the conductive portion facing the high-voltage discharge end is an inclined surface.

[0038] The circuit board 18 is connected to the electromagnet 12. The top cover 17 is arranged above the bottom shell 16. The fixed structure 15 and the bottom shell 16 form a cavity, which accommodates the circuit board 18 and other structures. The fixed structure 15 and the top cover 17 also form a cavity, which accommodates multiple components such as the electromagnet 12 and the bracket 13. The periphery of the high-voltage discharge end 11 is also provided with a protective cover 19. The protective cover 19 can be fixedly set on the top cover 17 as shown in the figure, or other independent movable setting schemes can be adopted. The protective cover 19 is a cylinder with a hollow window, which does not hinder the air circulation near the tip of the high-voltage discharge end 11 and does not affect the ionization effect of the ion generator.

[0039] The working process of the charge elimination structure of the ion generator is as follows: the initial state is that the electromagnet movable part 122 is stationary. At this time, the metal sheet 14 connected to the electromagnet movable part 122 is located above the high-voltage discharge end and maintains a safe distance (greater than 5mm) from the tip of the high-voltage discharge end 11. In this embodiment, the safe distance is the distance at which the position of the metal sheet has a smaller impact on the tip discharge of the high-voltage discharge end. The safe distance is set according to the discharge power of the high-voltage discharge end and is not limited in this embodiment. It should be noted that the larger the safe distance, the smaller the impact of the metal sheet on the tip discharge of the high-voltage discharge end. However, at the same time, the larger the distance, the larger the overall space occupied by the combination of the charge elimination structure and the ion generator. Taking into account the impact on tip discharge and the occupied space, in this embodiment, when the distance between the high-voltage discharge ends is 15mm to 45mm, the safe distance can be 5mm.

[0040] When the circuit board 18 supplies power to the electromagnet 12 via the leads, the electromagnet movable part 122 drives the metal sheet 14 downward, gradually shortening the distance between the metal sheet 14 and the high-voltage discharge end 11. Then, the pair of high-voltage discharge ends 11 gradually emerge from the pair of through holes 142. At this point, the distance between the metal sheet 14 and the pair of high-voltage discharge ends 11 is almost zero, and the charges of different electrical properties accumulated on the pair of high-voltage discharge ends 11 can be transferred to the metal sheet 14 and then neutralized. When the circuit board 18 stops supplying power, the electromagnet movable part 122 begins to reset and move upward, and the metal sheet 14 moves upward accordingly. After fully reset, the metal sheet 14 maintains a safe distance (greater than 5mm) from the tip of the high-voltage discharge end 11. By looping the above process, charge neutralization is achieved, which can ensure the voltage difference at the high-voltage discharge end, so that the ion generator can continue to operate normally and reduce the attenuation of the ionization effect. The safe distance can be ensured by limiting the movement length of the electromagnet movable part 122.

[0041] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
