And the mountain block is fixed to a fan(101) connected with static probe housing(201).

Description

      Ion Blower including the function of emitter clean}

Blowing type ion generating device to which the present invention belongs

When a high voltage is applied to the discharge needle, a corona discharge is generated from the discharge needle. The corona discharge ionizes the air molecules to generate positive and negative ions, and the positive and negative ions are forced into the product by using a fan for charging. The present invention relates to a blower type ion generating device for removing static electricity from an object.

In general, the blower type ion generating device is composed of an alternating current (AC) or direct current (DC) power supply unit, a high voltage power supply unit, and a discharge unit generating positive and negative ions by corona discharge. In addition, the control unit includes an ion sensor unit for detecting an ion generation amount, an error display unit for indicating whether it is normal or abnormal, and an ion control unit for controlling the amount of cation and anion generation.

Discharge needles that generate ions in such blow-type ion generators are contaminated, damaged, or deformed by dust and particles over time, and thus the ability to clean or replace the discharge needles is reduced. The discharge needle is fixed inside the device, so there is a problem that the user does not have to easily disassemble the device.

The present invention is to impart an antistatic needle cleaning function to the structure of a general blower type ion generator, the patents related to the first patent number 5,768,087 and second utility model No. 20-0341521 of Sunjae Hi-Tech.

The above patents have the same purpose in the function of cleaning the antistatic needle as in the present invention, and the members of the two prior patents are orthogonally sliding the brush around the axis of rotation of the fan by the rotational centrifugal force when the fan rotates. The brush is brought into contact with the antistatic needle by the transfer, and in the present invention, the brush rotating shaft is formed by a fixed shaft separately from the rotating shaft of the fan, not the orthogonal sliding method, so that the brush is inclined toward the housing during the rotating fan. The purpose is the same as the way to control the contact with the antistatic needle, but the driving method is different.

An object of the present invention is the process of cleaning or replacing the discharge needle because the discharge needle is contaminated, damaged or deformed by dust and particles (particles) as the time elapses in the blower type ion generator deteriorates the ability to remove static electricity In the discharge needle is fixed inside the device, such as having to disassemble the device there is a problem that the user is not easy to execute.

Among these problems, due to the contamination of the discharge needle, the generation rate of positive and negative ions generated is not constant, resulting in a decrease in the static electricity removal effect and the phenomenon of bias toward one ion polarity, resulting in an increase in the rate of product defects. The purpose is to solve the problem that the needle life is also shortened, resulting in a loss of maintenance and repair costs.

The present invention is to solve the above problems

The blower type ion generator is equipped with a brush that can perform the discharge needle cleaning function on the previous blower type ionizer. The brush contacts the discharge needle automatically by the rotation of the fan at the start and end of operation. We try to solve the problem by mounting a device that can.

When applying the blower type ion generator including the discharge needle cleaning function according to the present invention, since the ion balance is not collapsed due to the deterioration of ion generation over time, which was a problem of the conventional blower type ion generator, elimination of static electricity as the first time The effect can be maintained continuously, and there is no need to clean the static eliminator needle even at the end of operation, and it can be easily cleaned during continuous operation, which requires no separate management, resulting in increased work yield and reduced maintenance cost. The production yield can be increased due to the decrease in the occurrence rate.

      Blowing type ion generating device including the discharge needle cleaning function of the present invention

When the positive and negative ions are generated, a fan 101 having a function of blowing them to the surface of the product and the antistatic needle housing 201 equipped with the antistatic needle 301 for generating positive and negative ions by corona discharge are coupled to the upper part of the fan. Become; The mountain block 401 performing the antistatic needle cleaning function is coupled to the center of the combined fan, and the center of the mountain block has a rotor central axis 1001 and a housing 501 to which the brush 801 is coupled. To be mounted. The housing includes a torsion coil spring holder 1101 and a hinge block 601, and a fixed shaft 1201. A hinge block and a torsion coil spring 901, which are important elements of the movement of the blush, are coupled to the fixed shaft. Again, the hinge block has a structure in which one side of the brush holder 701 is fitted and the brush is coupled to the opposite side.

Here, the brush is inclined inside the housing so that the cleaning function is not performed when the fan is rotating and does not affect the amount of ions generated. This phenomenon is a hinge block, and when the fan is not rotating, the hinge block ends as shown in FIG. Due to the elasticity of the torsion coil spring, the brush attached to the center axis of the rotor and opposite to the hinge block is in contact with the antistatic needle. However, as shown in FIG. 3, when the fan rotates in the rotation direction, the hinge block located on the fixed shaft 15 mm away from the rotor center axis is biased toward the wall of the housing by the rotational force of the fan, that is, the centrifugal force. In this case, the brush opposite to the hinge block is inclined into the housing and separated from the antistatic needle. Accordingly, the cleaning function is not performed when the blower type ionizer is operated, and the ion generation is not affected. In addition, in order to prevent the center of gravity caused by the hinge block in the housing while the fan is rotating, the balance shape 1301 of FIG. Prevented.

The cleaning function of the antistatic needle which is an object of the present invention is made at the end of the operation of the blow-type ion generating device, or in the middle of operation in preparation for the continuous operation. In other words, when the fan is running, the rotational speed increases over about 3 seconds to reach a constant speed. After that, the brush is separated from the discharge needle, and the discharge needle is cleaned by the brush for 3 seconds when the rotation speed of the fan becomes constant. When the machine is stopped again, the rotation speed decreases, and the elasticity of the torsion coil spring The brush comes in contact with the tip of the antistatic needle and is cleaned.
