Description

TECHNICAL FIELD The present invention relates to a purification filter using a flexible substrate and a purifying device using the flexible filter,

The present invention relates to a purifying filter and a purifying device using the purifying filter. More particularly, the present invention relates to a purifying filter having high performance, low cost and low manufacturing cost because of the simple structure of the purifying filter, The present invention relates to a purification filter using a flexible substrate that can supply a device to a consumer and is easy to maintain and repair, and a purification apparatus using the same.

In recent years, the air quality and water quality in Korea has been deteriorating rapidly. Contaminants such as harmful heavy metal concentration, fine dust, formaldehyde, and airborne bacteria are increasing in the atmosphere due to rapid industrial development and various causes of the neighboring countries' industrial development.

In addition, the quality of drinking water is drastically deteriorating due to deterioration of water quality in the water intake area and the deterioration of the water pipe.

For this reason, the demand for purification devices such as air cleaners and water purifiers has been rapidly increasing in recent years.

Such a purifying apparatus is mainly composed of a micro-porous body and is configured to physically filter or adsorb contaminant particles inside the fluid. A typical example of the functional filter is a purifier using a photocatalyst.

A photocatalyst is a substance that causes a catalytic reaction when it receives light. Titanium dioxide is the most commonly used photocatalyst. The photocatalytic reaction using titanium dioxide has been widely used for a purification filter because of its effect such as antibacterial and deodorization.

That is, the method of deodorizing the odor of the air by allowing the photocatalytic reaction to occur by irradiating ultraviolet rays to the photocatalytic filter while allowing the fluid to pass through the photocatalytic filter coated with titanium oxide is a deodorization method widely used today.

Such deodorization by titanium dioxide has been mainly used for medium to large-sized purification apparatuses and is not widely used for small-sized or domestic purification apparatuses.

In the case of a large purifier having a large flow amount of the fluid to be purified and a large flow area, strong ultraviolet rays are generated, and when the photocatalytic filter is largely constituted, the deodorizing effect can be achieved without any problem.

However, in the case of a small air purifier, the size of the photocatalytic filter is limited, the size of the device for generating ultraviolet rays is limited, and the fluid flow rate is small. It is urgent to develop a purification device for the water.

In particular, household air purifiers can not help but consider the noise and also consume electricity very sensitively. However, in the past, the technology has been developed with a weight in the medium to large purification apparatus, so there is almost no technology suitable for such a new environment.

If the ultraviolet rays are intensively examined intensively with the intention of increasing the efficiency of the photocatalytic filter in a small-sized purifier, the efficiency of the photocatalytic filter can not be guaranteed and the material of the region irradiated with strong ultraviolet rays is rapidly denatured and the electricity consumption is inevitably increased.

In addition, the fact that more ultraviolet light sources are installed and the life span of the ultraviolet light source is shortened is another factor for raising the cost of the purification apparatus.

The FPCB 101 used in the purifying filter according to the present invention is an FPCB 101 that is flexible and has an insulation property and is mounted on a thin plate type film at predetermined intervals, A silicon layer 103 is formed by applying silicon to the upper surface of the silicon substrate 101 to be cured.

The purifying filter according to the present invention is constructed in the form of a pipe as shown in Figs. 3 and 5, and the purifying filter of the pipe type is configured to remove and sterilize the odor contained in the fluid while the fluid flows.

Since the FPCB 101 has flexibility, as shown in FIG. 2, the plate-shaped FPCB 101 is rounded in the form of a pipe to form a pipe.

2, the LED 102 mounted on the FPCB 101 is formed on the inner surface of the FPCB 101 so that when the LED 102 is supplied with power, 102, ultraviolet rays are irradiated into the inside of the FPCB 101 in the form of a pipe.

2, the reflector 104 that reflects light between the LEDs 102 of the FPCB 101 is configured so that the ultraviolet light emitted from the LED 102 is reflected again by the reflector 104, It is preferable to configure the FPCB 101 to be bent by the fluid flowing inside the FPCB 101.

By configuring the reflector 104 inside the pipe-shaped FPCB 101 to reflect the light emitted from the LED 102 as described above, the number of the LEDs 102 can be reduced and the fluid purification efficiency can be increased.

3 is an embodiment in which the present invention is configured in the form of an air filter 110 as an air purifying filter

As shown in Fig. 4, the FPCB 101 is not rounded in a pipe shape, and the rounded FPCB 101 is inserted into a pipe-shaped die holding pipe 106. [

As described above, the FPCB 101 is constructed by molding a flexible substrate in a pipe shape. The FPCB 101 is mounted on a die holding pipe 106 formed of a material such as silicon or synthetic resin Thereby maintaining the shape of the pipe and maintaining the airtightness of the fluid flowing inside the FPCB 101.

A driver bracket 105 for driving and controlling the LED 102 mounted on the FPCB 101 is provided on one side of the FPCB 101. The other side of the FPCB 101 is physically contacted with a fluid flowing in the FPCB 101 A photocatalytic bracket 111 is provided.

A driver for controlling the LED 102 is installed inside the driver bracket 105. The driver may be installed at a remote place away from the air filter 110. However, by fastening the driver to one side of the FPCB 101 as shown in FIG. 3, It is preferable to modularize together with the filter 110.

Since the driver is a known technology, a detailed description thereof will be omitted.

4, the photocatalytic bracket 111 may be formed of a photocatalytic material such as titanium dioxide (TiO ₂ ) inside a circular bracket, or may be formed in a mesh form in which a photocatalytic material such as titanium dioxide (TiO ₂ ) The flow resistance of the fluid flowing inside the FPCB 101 is minimized and the contact area with the fluid flowing in the FPCB 101 is maximized.

The air filter 110 constructed as described above is installed in a flow path of a purifier such as an air purifier so that ultraviolet rays irradiated from the LED 102 mounted on the FPCB 101 when the air flows inside the FPCB 101, The odor of the air is removed by the photocatalytic reaction of the photocatalyst 111, and the bacteria contained in the air are sterilized.

At this time, ultraviolet rays irradiated from the LED 102 are reflected by the reflector 104 by the reflector 104 installed between the LEDs 102 inside the FPCB 101 to improve the air purification efficiency.

The LED 102 is protected from foreign substances such as dust contained in the air by the silicon layer 103 formed on the inner surface of the FPCB 101 to prevent the brightness of the LED 102 from being lowered, Thereby preventing shortening of the service life.
