[0002] Currently, plasma generators use positive and negative voltages of high-voltage direct current to ionize the air and generate positive and negative ions. Generally, the drive circuit, boost coil, and high-voltage rectifier are distributed on the same PCB, meaning the high and low voltage components are within the same insulation system. This structure necessitates the boost coil to be separately insulated and potted. After assembly onto the PCB, a housing is required, and the PCB is then further insulated and potted.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] As attached Figure 1-9 The modular ion generator with detachable electrodes comprises an integrated high-voltage unit 1 based on a high-voltage rectifier circuit and an electrode assembly 2 based on a plasma release circuit. The conductive contact 4 in the slot 3 at the output end of the integrated high-voltage unit 1 is electrically connected to the plug 6 at the input end of the electrode assembly 2 via a conductive silicone rubber 5. The slot 3 and the plug 6 are fixed in place by a snap-fit assembly 7.

[0027] It adopts relatively independent high-voltage unit and electrode assembly. Different from the existing overall electrode connection method, the electrode assembly is contact-connected to the high-voltage unit through conductive silicone, which is convenient for replacement of the electrode assembly. The addition of a snap-on assembly can ensure that the connection of the electrode assembly relative to the high-voltage unit is reliable, and the electrode is easy to replace and will not easily loosen or fall off.

[0028] Among them, the high-voltage unit adopts an integrated high-voltage unit structure, which is mainly achieved by adding welding PIN pins of high-voltage components to the winding skeleton of the high-voltage transformer, and then directly welding the components of the rectifier part to the added PIN pins to form a high-voltage circuit. Finally, the high-voltage transformer potting shell is designed according to the actual molding height and shape. This eliminates the PCB part originally used for the high-voltage circuit, and the finished product does not require an additional shell, reducing the secondary potting process and materials, thereby reducing product costs.

[0029] Moreover, this structure is more suitable for modular production, improves manufacturing efficiency, and facilitates high-voltage testing of finished products. Dynamic testing can be achieved through self-made test fixtures, which improves the consistency and reliability of the entire positive and negative ion generator. There is no need to leave test holes on the finished product shell, which improves detection efficiency and moves the quality control point from the finished product to the unit, facilitating quality control and improving the qualified rate of the finished product.

[0030] The first pass rate of the ion generators using this integrated high-voltage unit is >99%, which is 3 percentage points higher than the 96% of the ion generators without the integrated high-voltage unit, thus generating significant economic benefits.

[0031] In addition, if Figure 9 As shown, in the internal circuit connection, an atypical triode stabilization circuit is adopted, and a common emitter amplifier circuit connection method is adopted, which mainly plays the role of negative feedback; by connecting a resistor R to the emitter, the common end of the input loop and the output loop is located below the emitter resistor R; the temperature sensitivity of semiconductor devices is used to perform temperature compensation to stabilize the operating point. In this example, the temperature sensitivity of the diode reverse current is used to select a diode D2 with a slightly larger reverse current for temperature compensation to stabilize the DC operating point Q, thereby forming a stable circuit; the resistor is a conventional resistor, and the diode is the existing technology.

[0032] The conductor convex contact 4 is provided at the bottom end of the slot 3, the inner end surface of the conductive silicone 5 is provided with a lower notch 5-1 for plugging with the conductor convex contact 4, and the outer end surface of the conductive silicone 5 is provided with an upper notch 5-2 for plugging with the plug 6. The conductive silicone 5 is elastically slidable along the direction in which the plug 6 is inserted into the slot 3;

[0033] The conductive silicone is embedded in the slot because its service life is longer than that of the motor assembly and does not need to be frequently replaced along with the electrode assembly. The conductive silicone is elastically slidably arranged in the slot to realize the switching action between the contact and separation states of the conductive silicone and the conductor convex contact. The specific implementation structure is as follows:

[0034] A support tube 8 is fixedly sleeved on the outside of the conductive silicone 5, and the support tube 8 is slidably arranged in contact with the inner wall of the slot 3. The bottom port of the support tube 8 is elastically connected to the bottom end of the slot 3 by a spring 9. The spring 9 is sleeved on the outside of the guide tube 10. The guide tube 10 is coaxially fixed to the bottom end of the slot 3. The outer wall of the guide tube 10 is slidably matched with the inner wall of the bottom end of the support tube 8, and the inner wall of the guide tube 10 is slidably matched with the outer wall of the bottom end of the conductive silicone 5;

[0035] Among them, since the conductive silicone is a soft object, the support tube plays a role in maintaining the shape and structure of the conductive silicone. It is sleeved on the outside of the conductive silicone so that it directly contacts the slot wall instead of the conductive silicone, thereby avoiding the wear caused by the relative sliding between the conductive silicone and the slot wall during movement. The guide tube arranged at the bottom of the slot mainly plays a guiding role to ensure the stable sliding of the conductive silicone. When the plug is inserted into the upper slot and pressed down, the conductor contact can be accurately inserted into the lower slot, thereby realizing the contact installation of the electrode.

[0036] The inner wall surface of the support tube 8 is provided with a plurality of first supporting ridges 8-1, and the inner wall surface of the guide tube 10 is provided with a plurality of second supporting ridges 10-1, and the first supporting ridges 8-1 and the second supporting ridges 10-1 are arranged in alignment along the axial direction. The outer wall surface of the conductive silicone 5 is provided with a plurality of embedding grooves 11, and the upper ends of the embedding grooves 11 are embedded with the first supporting ridges 8-1, and the lower ends of the embedding grooves 11 are slidably fitted with the second supporting ridges 10-1;

[0037] By setting the first supporting edge and the second supporting edge, they are engaged or slid with the embedding groove on the outer wall of the conductive silicone, mainly to further maintain the structure of the conductive silicone, so that it is not easy to deform during the process of plugging and unplugging and replacing the electrode assembly.

[0038] The conductive silicone rubber 5 is provided with a plurality of through cavities 12 along the axial direction. The plurality of through cavities 12 are evenly distributed around the upper notch 5 - 2 . The outer wall of the slot 3 is provided with a plurality of ventilation holes 13 along the axial direction.

[0039] Since conductive silicone easily generates a lot of heat during the conduction process, two sets of airflows can pass through a number of cavities and a number of ventilation holes, thereby carrying away the heat with the help of turbulence, thereby achieving a cooling effect.

[0040] The inner diameter of the cross section of the upper notch 5-2 fluctuates along the axial direction;

[0041] The inner diameter of the plug's cross section also fluctuates with the same amplitude along the axial direction, allowing the two to fit tightly together. This structure ensures that during the insertion and removal process, the plug is not inserted to the bottom or removed all at once, but there is a gradual and progressive buffering process, which provides good protection for the structure inside the slot.

[0042] The clamping assembly 7 includes a plurality of first elastic clips 14 arranged on the inner wall of the upper port of the slot 3, and a clamping plate 15 fixedly mounted on the root of the plug 6. The upper end surface of the clamping plate 15 is provided with a limiting groove 16 corresponding to the first elastic clips 14.

[0043] Two first elastic clips 14 are symmetrically provided, and two first through slots 17 for the first elastic clips 14 to pass through are symmetrically provided on the clamping plate 15 .

[0044] An elastic piece 18 is provided in each of the first through slots 17, one end of the elastic piece 18 is fixed close to one side of the plug 6, and the movable ends of the two elastic pieces 18 are separated to both sides in a V shape. A bayonet 19 is provided on the elastic piece 18, and a second elastic clip 20 corresponding to the bayonet 19 is also provided on the inner wall of the slot 3. The two first elastic clips 14 and the two second elastic clips 20 are equidistantly spaced in the circumferential direction of the inner wall of the slot 3, and the bottom surface of the limiting groove 16 is provided with a second through slot 21 for the second elastic clip 20 to pass through.

[0045] The first elastic clip 14 and the second elastic clip 20 are both ∠-shaped elastic plates, including a swinging portion 22 inclined away from the slot wall of the slot 3 and a limiting portion 23 at the swinging end of the swinging portion 22, and the limiting portion 23 is arranged parallel to the slot bottom of the slot 3;

[0046] It can be seen from the above features that the first elastic clip and the limiting groove are mainly engaged with each other to limit and fix the plug's upward movement along the axis of the slot, and the second elastic clip and the bayonet are engaged with each other to limit and fix the plug's rotation along the circumferential direction of the slot. In addition to opening various slots to cooperate with the elastic clips, the card plate also has the function of having its outer cylindrical surface fit with the inner wall of the slot. When the plug is fully inserted and fixed, the card plate also plays a role in sealing and dustproofing, thereby preventing the entry of dust from affecting the conductive properties of the conductive silicone.

[0047] The ∠-shaped structure of the elastic clip makes it easy to install and not easy to loosen or fall off after being inserted. When inserting the electrode assembly, it is mainly done by aligning the plug with the upper slot and then pressing down lightly by pinching the two elastic sheets so that the card slides over the swinging part of the elastic clip and moves to the bottom of the limit part. The card is rotated to adjust the angle so that the first elastic clip is locked in correspondence with the limit slot. At this time, the elastic sheet rotates to the position corresponding to the second elastic clip. Then let go and the elastic sheet resets so that the second elastic clip is engaged with the slot, thereby completing the entire connection process.

[0048] The first through-slot and the second through-slot facilitate the disassembly of the electrode assembly. When disassembling the electrode assembly, first pinch the two elastic sheets so that the swinging ends of the elastic sheets move toward the middle, thereby disengaging the second elastic clip from the bayonet. Then rotate 90° in any direction to make the first elastic clip correspond to the first through-slot and the second elastic clip correspond to the second through-slot. Then pinch the elastic sheet and pull it out along the axial direction of the slot.

[0049] As a preferred embodiment, the second elastic clip is smaller than the first elastic clip.

[0050] The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the above principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
