In addition, in the longitudinal cross-sectional view of FIG. 3, a part of inside is not made into a cross section.

In these drawings, reference numeral 1 denotes a light bulb type case, for example, a case main body 2 formed of a synthetic resin and a lid 3 formed of a synthetic resin and having a spherical surface with a large curvature whose tip approximates a plane. It is configured.
The case body 2 which is the base end side of the case 1 has a base part 4 (powered part) which is attached to a socket (power feeding part) (not shown) and connected to a commercial power source at one end (rear side). Is provided.
In addition, the lid 3 which is the tip side of the case 1 is provided with a plurality of concentric, for example, four cylindrical outlets 3 having the same diameter at the other end, that is, the tip.

The lid 3 is detachable on the other open end of the case body 2 by, for example, fitting, and a crosspiece 3b is provided as a safety means for preventing a finger or the like from being inserted into each outlet 3a. It has been.
And the base part 4 is provided with one electrode 4a at the center of one end and the other electrode 4b around it, like a normal light bulb.

Reference numeral 11 denotes an AC / DC converter. The AC / DC converter 11 converts the alternating current from the base 4 into direct current and outputs the direct current, and is disposed in the case body 2.
Reference numeral 12 denotes a step-up transformer which boosts a DC voltage output from the AC / DC converter 11 and is disposed in the case main body 2.
Reference numeral 13 denotes a partition wall that also serves as an attachment member, and is attached so as to partition the inside of the case body 2 into a front chamber 2f and a rear chamber 2r that houses the AC / DC converter 11 and the step-up transformer 12. The circular support cylinder part 13a which is located in the center of the four outlets 3a and protrudes to the front chamber 2f is provided.
Note that the partition wall 13 preferably has insulating properties.

Reference numeral 21 denotes a negative ion generator, which has an insulating property and has a support base 22 having a cylindrical portion mounted on the support cylindrical portion 13a of the partition wall 13, and a concentric circle disposed on the support base 22, It consists of four conductive first electrodes 23 that are pointed toward the center of the four outlets 3 a of the body 3.
The four first electrodes 23 are collectively connected to the negative electrode side of the step-up transformer 12.

Reference numeral 29 denotes a light emitting diode as an operating state display means for displaying an operating state or a non-operating state of the negative ion generator 21 (or an ozone generator 21A described later), and the lid 3 (or the case body 2). It is attached at an easy-to-see position.
A shows an air purifier and is comprised by each member mentioned above.
When the case main body 2 and the lid body 3 are moved together in the axial direction and are integrated by fitting, the positioning means provided on the case main body 2 and the lid body 3, for example, unevenness, etc. Each first electrode 23 corresponding to the center of the outlet 3a is located.

Next, the operation will be described.
First, when a DC negative high voltage is supplied from the step-up transformer 12 to the first electrode 23, a silent corona discharge occurs between the tip of each first electrode 23 and the atmosphere in front of each first electrode 23. Negative ions are generated, and negative ions are generated so as to pass through the corresponding outlets 3a from the first electrode 23 side by the Coulomb force charged in the atmosphere in front of the first electrodes 23.
Since negative ions are generated from the first electrode 23 side to the other side of the outlet 3a, the negative ions diffuse, so that the negative ions clean the air in the room where the air purifier A is provided.

Thus, when the negative ion generator 21 is operating, the light emitting diode 29 is turned on to indicate that negative ions are being generated.
However, when the operation of the negative ion generator 21 is stopped by operating a switch or the like, the light emitting diode 29 is turned off, indicating that no negative ions are generated.

The principle that these negative ions clean the air is that they are attached to positive ions (micron-order dust, mite carcasses, spiders, bacteria, pollen, etc.) that are said to be bad for the human body and become negative, becoming heavier than air. The air is cleaned by falling onto the floor and adsorbing onto the positively ionized floor.
And what fell on the floor is sucked out by a vacuum cleaner.
By the way, although 1 million or more negative ions are always released from the first electrode 23 per 1 ml, since the decay is fast, it is desirable to release a large amount by increasing the number of the first electrodes 23.

In addition, negative ions are said to have a “forest bathing effect”, which relaxes the mind and body, prevents cellular oxidation, activates metabolism, enhances lung and respiratory functions, and improves endocrine function. To improve the hematopoiesis.
Tests using AMI (Terminal Organ Function Measuring Instrument) have demonstrated that this function can be achieved when patients are exposed to artificially generated negative ions to increase blood flow and improve air flow in the body. ing.

As described above, according to the first embodiment of the present invention, the case 1 is made into a light bulb type, and the base portion 4 that is directly attached to the socket is provided. Negative ions can be diffused from above the room or the like to clean the indoor air.
Since the case 1 is a hanging type as a light bulb type, it is possible to provide an air purification apparatus A that is novel and varied, which is different from the installation type installed on the floor, desk, or the like.

In addition, since the crosspiece 3b is provided at the blowout port 3a, it is safe to insert a finger or the like into the blowout port 3a to prevent the first electrode 23 from being touched.
Furthermore, since the case 1 is divided into the case body 2 and the lid body 3 and the lid body 3 can be attached to and detached from the case body 2, the inside of the lid body 3 can be simply removed by simply removing the lid body 3 from the case body 2. And it can be easily cleaned and washed.
In the air cleaning apparatus A of the first embodiment, since discharge occurs between the first electrode 23 and the atmosphere, that is, no electrode facing the first electrode 23 is provided, and the inside of the case 1 is almost not. Since there is no dirt, there is almost no need to clean and wash the inside of the case 1, so that maintenance is simplified.

Further, since the inside of the case 1 is hardly soiled, the lid body 3 may not be attached to and detached from the case body 2 but may be fixed or integrated.
Furthermore, since the light emitting diode 29 is provided, whether or not the air purifier A is emitting negative ions can be confirmed by turning on or off the light emitting diode 29.

In addition, the air for generating the airflow which passes the cylindrical body 25 and the blower outlet 3a sequentially from the 1st electrode 23 side is supplied through the opening 2a.

An air flow containing negative ions and ozone is generated from the first electrode 23 side of the cylindrical body 25 to the outlet 3a, so that negative ions and ozone are transported and diffused. As described above, the indoor air can be cleaned and sterilized or deodorized by the oxidative decomposition action of a small amount of ozone (0.05 PPM or less).
At this time, the dust is charged and adheres to the second electrode 24, that is, each cylindrical body 25, so that the cylindrical body 25 becomes dirty. Therefore, when cleaning and cleaning the dirty cylindrical body 25, the lid 3 is attached to the case body. 2, the second electrode 24 is cleaned and washed, and then the lid 3 is attached to the case body 2, or the second electrode 24 is further detached from the lid 3 and the second electrode 24 is cleaned and washed. Thereafter, the lid 3 may be attached to the case body 2 after the second electrode 24 is attached to the lid 3.
