Description

Technical Field

[0001] This utility model relates to the field of static electricity elimination technology, and specifically to a novel static electricity eliminator. Background Technology

[0002] Static eliminators, also known as static electricity removal devices, generally consist of a high-voltage power generator and a discharge electrode (usually made into an ion needle). They ionize the air into a large number of positive and negative ions through high-voltage corona discharge at the tip, and then use wind to blow the large number of positive and negative ions onto the surface of the object to neutralize static electricity, or the static eliminator can be placed directly close to the surface of the object to neutralize static electricity.

[0003] Existing static eliminators typically consist of an aluminum alloy metal casing, an insulating strip mounted on the casing, and a circuit board and discharge electrode housed within the insulating strip. In humid or harsh environments, substances that may become conductors, such as water vapor, cotton fibers, or synthetic fibers, can conduct electricity between the discharge electrode and GND (the ground wire, typically connected to the aluminum alloy metal casing). This can cause high-voltage electricity to directly arc to ground, resulting in the insulation being burned out or broken down, ultimately damaging the entire static eliminator.

[0004] Therefore, it is necessary to provide a new type of static eliminator to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a novel static eliminator that increases the difficulty for substances in the environment that may become conductors to conduct electricity to the discharge electrode and metal casing of the static eliminator, thereby improving the stability of the novel static eliminator.

[0006] This utility model is achieved through the following technical solution: A novel static eliminator is provided, comprising a metal shell, an insulating strip, and a discharge device disposed within the insulating strip. The insulating strip has an H-shaped cross-section, with the upper part of the insulating strip serving as a receiving groove in which the discharge device is vertically installed. The lower part of the insulating strip serves as a fixing groove, which is divided by a partition into a snap-fit ​​groove and a connecting groove that are arranged vertically and interconnected. The metal housing is used to connect to grounding equipment. The metal housing includes a snap-fit ​​plate and a connecting part fixed below the snap-fit ​​plate. The snap-fit ​​plate snaps into the snap-fit ​​groove. It also includes conductive structures, which, in conjunction with the discharge device, generate a strong electric field and ionize the air.

[0007] Furthermore, the conductive structure is a conductor connected to the ground wire, which passes through the interior of the insulating strip and is located on both sides of the discharge device.

[0008] The conductive structure is a conductor connected to the ground wire. The conductor is inserted inside the insulating strip. A strong electric field is generated through the conductor and the high-voltage discharge device, thereby ionizing the air.

[0009] Furthermore, insulating adhesive is applied between the metal casing and the discharge device inside the insulating strip.

[0010] Since the insulating strip contains a conductor that can form an electric field with the discharge device, the purpose of the insulating adhesive is to prevent the discharge device from forming an electric field with the metal casing.

[0011] Furthermore, the conductive structure is a conductor portion, which is symmetrically connected to both ends of the snap-fit ​​plate, and the end of the conductor portion extends obliquely upward to the inside of the receiving groove sidewall of the upper part of the insulating strip.

[0012] The metal casing is connected to the ground wire, and conductors are symmetrically arranged at both ends of the snap-fit ​​plate. Under the action of high voltage, the discharge device forms a strong electric field with the conductors, thereby ionizing the air and eliminating dust caused by static electricity in the environment.

[0013] Furthermore, the inner wall of the snap-fit ​​groove is provided with multiple protrusions on the upper and lower surfaces that can abut against the snap-fit ​​plate.

[0014] Multiple protrusions can be provided on the inner wall of the snap-fit ​​groove. When the snap-fit ​​plate is placed in the snap-fit ​​groove, the protrusions can abut tightly against the snap-fit ​​plate, increasing the friction between the snap-fit ​​groove and the snap-fit ​​plate and improving the stability of the snap-fit ​​plate in the snap-fit ​​groove.

[0015] Furthermore, the insulating strip has limiting plates on both sides of the lower opening of the connecting groove, which are parallel to the partition. The limiting plates abut against the bottom surface of the connecting part to restrict the position of the metal shell in the fixed groove.

[0016] Limiting plates are provided on both sides of the opening of the connecting groove. The limiting plates abut against the connecting part to limit the position of the metal shell in the fixed groove.

[0017] The beneficial effects of this utility model are: This invention extends the conductive path between the discharge device and the metal shell by placing the metal shell in the fixing groove below the insulating strip. This minimizes the possibility that substances in the environment that may become conductors, such as water vapor, cotton fibers, or chemical fibers, can conduct electricity between the discharge device and the metal shell of the static eliminator. This increases the difficulty for substances in the environment that may become conductors to conduct electricity between the discharge electrode and the metal shell of the static eliminator, thereby improving the stability of the new static eliminator.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] Example 1: like Figure 1 and Figure 2 As shown, a novel static eliminator includes a metal housing 1, an insulating strip 2, and a discharge device 3 disposed within the insulating strip 2. In this invention, the discharge device 3 utilizes conventional technology and can be a common high-voltage power generator and discharge electrode structure. Its function is high-voltage discharge, and its specific structure is not limited. The insulating strip 2 has an H-shaped cross-section. The upper part of the insulating strip 2 is a receiving groove 21, in which the discharge device 3 is vertically installed. The lower part of the insulating strip 2 is a fixing groove 23, which is divided by a partition into a vertically arranged and interconnected snap-fit ​​groove 231 and a connecting groove 232.

[0025] The metal housing 1 is used to connect to grounding equipment. The metal housing 1 includes a snap-fit ​​plate 11 and a connecting part 12 fixed below the snap-fit ​​plate 11. The snap-fit ​​plate 11 snaps into the snap-fit ​​groove 231. The inner wall of the snap-fit ​​groove 231 is provided with a plurality of protrusions on the upper and lower sides that can abut against the snap-fit ​​plate 11.

[0026] The insulating strip 2 has limiting plates 234 parallel to the partition on both sides of the lower opening of the connecting groove 232. The limiting plates 234 abut against the bottom surface of the connecting part 12 to restrict the position of the metal shell 1 in the fixing groove 23.

[0027] It also includes a conductive structure, which, in conjunction with the discharge device 3, generates a strong electric field and ionizes the air.

[0028] The conductive structure is a conductor 22 connected to the ground wire. The conductor 22 passes through the interior of the insulating strip 2 and is located on both sides of the discharge device 3. To ensure stability, two protrusions 24 are symmetrically formed on the upper two sides of the insulating strip 2 on both sides of the discharge device 3. The conductor 22 passes through the protrusions 24. Insulating adhesive (not shown in the figure) is applied between the metal shell 1 and the discharge device 3 inside the insulating strip 2.

[0029] A fixing groove 23 is provided at the end of the insulating strip 2 away from the discharge device 3. The metal shell 1 is placed in the fixing groove 23 to extend the conduction path between the discharge device 3 and the metal shell 1. By wrapping the metal shell 1 inside the insulating strip 2, the path between the discharge device 3 and the metal shell 1 of the static eliminator is extended, thereby increasing the difficulty for substances in the environment that may become conductors to conduct the discharge device 3 and the metal shell 1 of the static eliminator, and improving the stability of the new static eliminator.

[0030] Example 2: like Figure 3 and Figure 4 As shown, in this embodiment, the conductive structure is a conductor portion 13, which is symmetrically connected to both ends of the snap-fit ​​plate 11, and the end of the conductor portion 13 extends obliquely upward to the inside of the receiving groove 21 side wall of the upper part of the insulating strip 2. The conductor portion 13 can be integrally formed with the metal housing 1, and a cavity for accommodating the conductor portion 13 is reserved between the two side walls of the insulating strip 2, which facilitates the installation of the metal housing 1 and the insulating strip 2.

[0031] In this embodiment, the insulating strip 2 does not contain a conductor 22 that interacts with the discharge device 3. Instead, the metal shell 1 is connected to the ground wire, and the two ends of the snap-fit ​​plate 11 are symmetrically provided with conductor portions 13. Under the action of high voltage, the discharge device 3 forms a strong electric field with the conductor portions 13, thereby ionizing the air and ultimately eliminating dust caused by static electricity in the environment.

[0032] Each conductor portion 13 extends upward along one end of the snap-fit ​​plate 11, thereby approaching the discharge device 3, so that the discharge device 3 and the conductor portion 13 can form a strong induced electric field, thereby ionizing the air.

[0033] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
