Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air ion generator, and more particularly to an air ion generator for industrial, medical and environmental hygiene purposes.

[0002]

2. Description of the Related Art As an air ion generator, a type of high-pressure discharge between a positive electrode and a negative electrode has been proposed.
Not only does this device generate toxic ozone, but dust and dirt easily adhere to the electrodes, which is inefficient and pollutes the air.

[0003]

In order to solve the above-mentioned drawbacks, in the invention of Japanese Patent Laid-Open No. 61-61634, a step of forming a water film by squeezing a vent type ceramic porous body with water,
A process of splitting the water film into minute water droplets has been proposed, but it has a drawback that the device is complicated and the efficiency is low, so that a large amount of air ions cannot be continuously generated.

[0004] Conventionally, it is said that a large amount of air ions, particularly negative ions which are beneficial to the human body, are generated by the so-called Leonard effect due to the splashing of water in places where there are beaches and waterfalls, which is good for health. The present invention is intended to continuously generate a large amount of air ions by simply artificially producing ultrafine water droplets corresponding to water spray while cleaning the air used for ionization.

[0005]

In order to achieve the above object, the present invention provides an air ion generating tower with an intake port and an exhaust port, and installs a high-speed rotating brush in a flow path between the intake port and the exhaust port. By disposing an ultra-fine water droplet forming screen between the rotating brush and the intake port, and by supplying water to the high-speed rotating brush by the water supply means, fine water droplets are formed by the centrifugal force of the high-speed rotating brush, and from the intake port. Of air is passed through an ultra-fine water droplet formation screen installed under the high-speed rotating brush, and the air is brought into contact with the ultra-fine water droplets that collide with the screen and are split, to continuously generate a large amount of negative air ions, Next, the fine water droplets formed by the high-speed rotating brush are made to collide with the inner wall of the air ion generation tower, and further divided into fine particles to make them contact with the ultrafine water droplets, resulting in a larger amount of negative air ions. It is intended to generate connection basis.

[0006]

According to the above construction, when water is supplied to the rotating brush while the rotating brush is rotated at high speed by disposing the ultra-fine water droplet forming screen means on the inlet side of the rotating brush between the intake port and the exhaust port, water droplets Are finely divided by the centrifugal force of the rotating brush. The fine water droplets collide with the screen to become ultrafine water droplets. While passing through the screen means from the air inlet, the intake air comes into contact with the ultrafine water droplets that have collided with the screen means to generate negative air ions and be cleaned. Further, in the air, fine water droplets formed by the high-speed rotating brush collide with the air ion generation tower and come into contact with the ultrafine water droplets that are split, so that a larger amount of negative air ions are generated.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The air ion generating tower 10 has an intake port 12 and an exhaust port 14
And the high-speed rotating brush 16 is arranged in the middle thereof. The high-speed rotary brush 16 is a rotary shaft 16a in which a large amount of dense brushes made of metal or plastic are planted. Water is supplied from the nozzle 18a toward the rotary shaft 16a of the rotary brush 16 by bringing a water supply means including a plurality of water supply pipes 18 close to the outer periphery of the rotary brush 16. The water supply pipe 18 is connected to a water receiving tank 22 via a main pipe 20 and is supplied with water by a pump 24. An ultrafine water droplet forming screen means 25, which is a special screen such as an art metal, an expanded metal, or the like, is disposed between the intake port 12 and the rotating brush 16. Water tank 22
A pack 26 having a silver ion coating material such as sand or glass for sterilization packed therein is soaked therein as a filtering agent. The silver ions are slightly eluted in the water in the water receiving tank 22 to remove bacteria, fungi, algae, etc. in the water receiving tank 22, the inner wall of the air ion generating tower 10, the screen means 25, and the rotating brush 16, and The silver ions in the ultra-fine water droplets effectively sterilize bacteria and bacteria in the air to clean the water and air for generating air ions. An intake fan 28 is arranged at the intake port 12. On the upper part of the high speed brush 16, there is arranged a driminator 30 or a demister 32 for removing water drops in the air.

In the above structure, when the rotary brush 16 is rotated at a high speed by a drive means (not shown) such as a motor, when water is supplied from the water supply hole 18a toward the rotary shaft 16a, water droplets are generated by the centrifugal force of the rotary brush 16. It becomes fine water droplets and scatters in the radial direction. The air supplied from the intake port 12 by the fan 28 collides with fine water droplets formed by the action of the centrifugal force of the rotating brush 16 while passing through the gap between the linear portions 25, and negative air ions are generated. , Line part 2
Negative air ions are generated by coming into contact with the ultra-fine water droplets that collide with 5 and are split. Next, the air contacts the ultrafine water droplets formed by the collision of the fine water droplets formed by the centrifugal force of the high-speed rotating brush with the inner wall of the air ion generation tower, and negative air ions are generated. As described above, a large amount of negative air ions are efficiently generated in two stages, that is, the ultrafine water droplets that collide with the screen means and are fragmented and the ultrafine water droplets that collide with the inner wall of the air ion generating tower and are fragmented. In addition, the structure of the device is extremely compact, the installation space is minimized, and the running costs of electricity and water volume are significantly reduced.

2 and 3 show an example of the screen means 25 composed of a stub screen, in which 25a is a base metal, 25b is a first linear portion made of a stab formed on one side of the base metal 25a, and 25c is Base metal 2
The 2nd linear part which consists of a stab formed in the opposite side of 5a is shown. A part of the air collides with the base metal 25a, and the other part of the air collides with the base metal and the stubs 25b, 2
Pass through the gap of 5c. At this time, the air collides with the fine water droplets 17 and the screen 25 and collides with the ultrafine water droplets that have been split, so that negative air ions are efficiently generated.

[0010]

According to the present invention, a large amount of negative air ions can be efficiently generated while cleaning the air by a combination of a high speed brush having dense brushes and a screen means. Not only fine dust due to fine water droplets,
Even bacteria and viruses can be removed to generate air ions that are desirable for environmental hygiene. According to this method, the structure of the device is simplified, and the pump can be used as a general-purpose water supply pump, and the water consumption and the power consumption of the pump and the rotating brush can be suppressed to a low level. Also, the running cost can be significantly reduced.
