Description

{Photographing apparatus having air pollutant purification device}

The present invention relates to a camera device having an air pollutant purification device, and more specifically, to a camera device having a CCTV camera for capturing real-time images of a predetermined space, and having an air pollutant purification device that absorbs, stores, and decomposes odors or pollutants in a target object or target space to reduce them or purify and sterilize them through the CCTV camera.

Typically, pollutants are emitted indoors in buildings such as homes or offices, and from a variety of other facilities such as cars, heating systems, or industrial facilities such as power plants and factories.

The above pollutants contain excessive amounts of harmful particulate pollutants such as various types of dust and sulfur oxides, and are dangerous when released into the atmosphere, becoming a major cause of environmental pollution.

And, the above-mentioned harmful pollutants are contained in the atmosphere and then chemically react with fog, clouds, and rain and physically change into acidic substances such as sulfuric acid, nitric acid, and hydrochloric acid, and fall as acid rain. Since this acid rain cannot be controlled by humans, it harms a wide area and many plants, animals, and humans.

Therefore, devices are being installed to purify pollutants in order to prevent environmental pollution and provide a more pleasant environment.

In general, CCTV (Closed Circuit Television) cameras are systems that transmit images to specific recipients using wired or special wireless transmission lines in specific buildings or facilities, and are used for various purposes such as industrial, educational, medical, traffic control surveillance, disaster prevention, and in-house image information transmission.

Currently, the CCTV cameras, etc. are being combined with various types of devices such as air purification and temperature and humidity control in addition to their original purpose, so that they can be used for various purposes with a single device, thereby diversifying their uses. In addition, since the devices can be used as a single device without having to be installed individually, it can be seen that this increases the convenience of installation and the usability of the space.

That is, as disclosed in Korean Patent Publication No. 10-1851588, an air purifying device is used in combination with a CCTV camera, and as disclosed in Korean Patent Publication No. 10-2069124, a temperature and humidity control device is used in combination with a CCTV camera.

Therefore, in the current situation where interest in health care is heightened in response to constant exposure to viruses or harmful gases while experiencing the COVID19 pandemic, the applicant of the present invention has implemented a method that can utilize the currently used device and the place where the device is installed without having to use a separate device and place for air purification and sterilization.

First, it should be noted that among the drawings, identical components or parts are indicated by the same reference numerals. In addition, in describing the present invention, specific descriptions of related known functions or configurations will be omitted in order to avoid obscuring the gist of the present invention.

According to an embodiment of the present invention, a camera equipped with an air pollutant purification device for photographing a predetermined space in real time and capable of absorbing, storing, and decomposing odors or pollutants in an object or a target space to reduce them or purify and sterilize them, as illustrated in FIG. 1, is configured with a camera (100), preferably a CCTV camera, installed at the front to photograph a predetermined space; and a purification and sterilization module (200) installed at the rear of the camera (100) to purify and sterilize pollutants in polluted air in the atmosphere.

The above purification and sterilization module (200) is composed of a main body (210), a filtering panel (220), a sterilization module (230), and a smart control unit (240), as shown in FIGS. 2 and 3.

The above main body (210) is equipped with a first intake port (211) for sucking in air containing pollutants and a first exhaust port (212) for discharging air purified and sterilized of the pollutants, and is installed at the rear of the camera (100) and on a fixed body (not shown) such as a wall.

In addition, the main body (210) is provided with an air purification display unit (215) as shown in Fig. 1, and the air purification display unit (215) is formed to be lit through a smart control unit (240) when purified and sterilized air is discharged.

The above filtering panel (220) is inserted and installed into the fitting portion (213) provided in the first intake port (211) of the main body (210), and as shown in FIG. 6, it serves to purify and discharge pollutants in polluted air drawn in through the first intake port (211), and as shown in FIGS. 4 and 5, it is composed of a first outer layer (221) and a second outer layer (222) formed of a net-shaped structure, a first filtering member (223) installed between the first outer layer (221) and the second outer layer (222), and a support plate (224) that supports the first outer layer (221), the second outer layer (222), and the first filtering member (223).

And, the first filtering member (223) is permanently or non-permanently connected between the first outer layer (221) and the second outer layer (222) through stitching or heat welding.

Here, the first filtering member (223) is made of porous activated carbon having a pore size of 300 microns to 500 microns.

The reason why the pore size of the activated carbon, which is the first filtering member (223), is limited to 300 microns to 500 microns is because it was found to have the best filtering effect on contaminants, taking into consideration the efficiency of filtering.

That is, the smaller the pore size, the better the filtering efficiency, but considering the adsorption rate and breathability of fine pollutants such as taste and odor components, below 300 microns, the air breathability becomes weak, and above 500 microns, the adsorption rate of pollutants decreases.

The first outer layer (221) and the second outer layer (222) are made of polyester or polypropylene, and beyond simply supporting the first filtering member (223) and allowing air to pass through, they enable pre-filtering of contaminants in the air and have an antibacterial property while promoting air permeation.

In addition, the first outer layer (221) and the second outer layer (222) are made of fine fabrics with a mesh structure so as to trap volatile fine particles and moisture in the air.

As described above, the above support plate (224) serves to collectively support the filtering panel (220) composed of the first outer layer (221), the second outer layer (222), and the first filtering member (223), so that the filtering panel (220) can be easily inserted and installed into the fitting portion (213) provided in the first suction port (211) of the main body (210), or can be easily separated from the fitting portion (213).

The above sterilizing module (230) is fixed to the bottom of the main body (210) with screws, etc., as shown in FIG. 3, and serves to suck in purified air discharged through the filtering panel (220), sterilize it, and discharge it through the first discharge port (212). As shown in FIGS. 7 to 12, it is composed of a housing (231), a photocatalytic filter (232), a light source unit (233), an elastic block (234), a spacer (235), and a fan unit (237).

The above housing (231) is provided with a second intake port (231-1) for sucking in purified air through the filtering panel (220) and a second discharge port (231-2) for discharging purified air after being sterilized, and is fixed to the bottom of the inside of the main body (210) using screws or the like as described above.

The above photocatalytic filter (232) is provided with a ventilation hole (232-1) that allows purified or sterilized air to pass through, is placed inside the housing (231), and has an aluminum substrate and a titanium dioxide (TiO2) coating layer coated on the outer surface of the aluminum substrate through a chemical vapor deposition (CVD) method, thereby sterilizing purified air introduced through the second intake port (231-1).

The above photocatalytic filter (232) may be formed in a square plate shape that divides the inside of the housing (231) into front and back.

In addition, the photocatalytic filter (232) is supported on the inner wall of the housing (231) and fixed at a predetermined position inside the housing (231).

The above photocatalytic filter (232) is provided with a ventilation hole (232-1), and the ventilation hole (232-1) is formed to penetrate the photocatalytic filter (232) from front to back, thereby providing a flow path for sterilized air from front to back of the photocatalytic filter (232).

The above ventilation hole (232-1) can be implemented in various shapes or arrangements as long as it can provide an air flow path before and after the photocatalytic filter (232).

In the present embodiment, the ventilation hole (232-1) is formed in a slit shape extending approximately in the horizontal direction, as illustrated in FIG. 9, and is exemplified as having several of them provided on the outer surface of the photocatalytic filter (232).

In addition, a plurality of ventilation holes (232-1) are spaced apart from each other in the front, back, left and right directions on the outer surface of the photocatalytic filter (232), so that they can be evenly distributed over the entire surface of the photocatalytic filter (232).

The above-described ventilation hole (232-1) enables air to have a sufficient residence time around the photocatalytic filter (232).

And, as needed, the ventilation hole (232-1) is formed to open toward the upper or lower side.

That is, the ventilation hole (232-1) can be formed to discharge air upward or downward from the front of the photocatalytic filter (232).

In particular, when a plurality of photocatalytic filters (232) are provided as described later, the ventilation holes (232-1) of each photocatalytic filter (232) are formed to open toward the upper or lower side, and it is possible for a photocatalytic filter (232) having a ventilation hole (232-1) facing upward and a photocatalytic filter (232) having a ventilation hole (232-1) facing downward to be alternately and repeatedly arranged along the direction of air flow.

The above configuration allows the air to have a sufficient residence time inside the housing (231) and enables the removal of harmful substances evenly throughout the entire area of the air.

Meanwhile, the photocatalytic filter (130) is composed of a substrate and a titanium dioxide (TiO2) coating layer.

Preferably, the substrate may include an aluminum substrate, and as illustrated in FIG. 13, a titanium dioxide coating layer may be coated on the aluminum substrate through chemical vapor deposition (CVD).

For reference, in the production of a photocatalytic filter (130), fixation methods for forming a titanium dioxide coating layer may include a powder mixing method, a surface oxidation method, and a sol-gel method.

The powder mixing method is a method that uses powdered titanium dioxide, and is generally easy to manufacture, so it is widely used in paints, coatings, paper, glass fiber, non-woven fabrics, fluorine sheets, etc.

However, according to the test conducted by the applicant, in the photocatalytic filter (232) of the present embodiment, the powder mixing method has the problem that the active surface is reduced by the binder, the powder is relatively easily detached, and the binder also deteriorates.

Accordingly, there is a problem that the reactivity is low and the activation by UV-A light sources with relatively long wavelengths is insufficient.

The surface oxidation method is a method that uses metal titanium and titanium alloy plates, and is used in titanium dioxide electrodes and cathode oxidation building materials.

The surface oxidation method can form a thin film with a relatively dense structure on a substrate, but it is not suitable for objects with a large specific surface area, and thus has a problem in that its application to a photocatalytic filter (130) such as the present embodiment is limited.

The sol-gel method is a method that uses organic titanium compounds and titania sol, and is mainly used in the fields of glass products and metal ceramics.

The sol-gel method has the advantage of allowing the surface area to be expanded by mixing an organic material that serves as a mold, but it generally requires firing at a high temperature of 450 to 600 degrees, so the productivity is not good, and according to tests conducted by the applicant, the reactivity is also lower than that of the chemical vapor deposition method of the present example.

This causes a problem, especially as with the powder mixing method above, in that the activation level is not sufficiently increased by the UV-A light source.

According to the above, the photocatalytic filter (232) according to the present embodiment uses a method of forming a titanium dioxide coating layer on a substrate through a chemical vapor deposition method.

The above method not only facilitates control of the film thickness and surface area of the composition, but also increases the integration and reaction surface area, thereby enabling sufficient activation even through a UV-A light source.

That is, a light source unit (233) was used to irradiate UV-A light having a wavelength of 320 to 400 nm toward the photocatalytic filter (232).

The light source unit (233) has a plate shape that divides the inside of the housing (231) into front and back to correspond to the photocatalytic filter (232).

Additionally, the light source unit (233) is supported on the inner wall of the housing (231) and fixed at a predetermined position inside the housing (231).

In the present embodiment, the light source unit (233) is exemplified as having a generally square plate shape to correspond to the photocatalytic filter (232). However, the shape of the light source unit (233) may be modified in various ways to correspond to the shape of the housing (231), etc., and is not necessarily limited to the exemplified shape.

The above light source unit (233) is positioned at a predetermined distance from the photocatalytic filter (232) and is formed to irradiate ultraviolet rays toward the photocatalytic filter (232).

In the present embodiment, the light source unit (233) is positioned at a predetermined distance behind the photocatalytic filter (232) to irradiate ultraviolet rays toward the rear of the photocatalytic filter (232), but the front-back position between the light source unit (233) and the photocatalytic filter (232) may be changed as needed and is not necessarily limited to what is exemplified.

The above light source unit (233) may be provided with a ventilation hole (not shown), and the ventilation hole may be formed to penetrate the light source unit (233) forward and backward, thereby providing a flow path through which air inside the housing (231) may flow forward and backward.

The above ventilation hole may be any hole that can provide an air flow path before and after the light source unit (233), and may be implemented in various shapes or arrangements, and may be provided in multiple numbers as needed.

The above light source unit (233) may be equipped with a substrate and one or more light-emitting diodes (LEDs) arranged on the substrate.

Preferably, a plurality of light-emitting diodes are provided and can be evenly arranged on the entire surface of the light source unit (233) with a predetermined interval or arrangement. This is to ensure sterilization or filtration performance by sufficiently utilizing the entire surface of the photocatalytic filter (232) for reaction.

In this embodiment, the light-emitting diode can irradiate UV-A light with a photocatalytic filter (232). That is, the light-emitting diode can be formed with a UV-A lamp.

The above UV-A lamp can irradiate ultraviolet rays having a wavelength of 320 to 400 nm to the photocatalytic filter (232) as described above.

A photocatalytic filter (232) having a titanium dioxide coating layer formed through a chemical vapor deposition method can be operated to decompose organic and inorganic substances in the air and reduce them to water and carbon dioxide in response to UV-A light.

The above elastic blocks (234) are placed on the left and right sides of the inside of the housing (231) so that the edges of the photocatalytic filter (232) and the light source unit (233) are elastically fitted together.

The above elastic blocks (234) may be provided in pairs corresponding to one inner wall of the housing (231) and the corresponding inner wall of the opposite side.

Figure 11 is an enlarged view of an elastic block (234) placed on one inner wall, and the elastic block (234) is formed of an elastic body having a predetermined thickness.

In addition, the elastic block (234) can be formed to be extended with a predetermined front-back width and vertical height to correspond to the arrangement positions of the photocatalytic filter (232) and the light source unit (233).

The elastic block (234) as described above is elastically deformed by being pressed against the edge portion of the photocatalytic filter (232), thereby fixing the photocatalytic filter (232), etc., inside the housing (231).

The above photocatalytic filter (232), etc., is installed inside the housing (231) by being inserted downward from the upper side of the elastic block (234), thereby making assembly of the photocatalytic filter (232), etc., easier.

In addition, since the elastic block (234) has the function of buffering impact applied from the outside of the housing (231), damage to the photocatalytic filter (232), etc. can be effectively prevented.

The above spacer (235) is placed between the photocatalyst filter (232) and the light source unit (233) as shown in FIG. 11, thereby supporting the photocatalyst filter (232) and the light source unit (233) at a predetermined front-back interval.

In addition, an adjustment pin (236) for fixing a photocatalytic filter (232) or a light source unit (233) and adjusting a predetermined installation interval is screwed onto both ends of the spacer (235).

The above adjustment pin (236) can be screw-connected to the spacer (235) and connected to an end of the spacer (235) with the photocatalytic filter (232) or the light source unit (233) interposed therebetween, thereby fixing the photocatalytic filter (232) or the light source unit (233) to the spacer (235).

The above adjustment pin (236) is supported by a support rib (239) provided in the housing (231) or, if a plurality of adjustment pins (236) are provided, by an end of another adjustment pin (236), so that each photocatalytic filter (232) or light source unit (233) can be appropriately fixed inside the housing (231).

In addition, the adjustment pin (236) can have the function of adjusting the position or spacing of the photocatalytic filter (232) or the like during assembly through screw connection.

The fan unit (237) is installed at the front (see FIGS. 3 and 7) or rear (see FIGS. 10 to 12) of the housing (231), and serves to draw purified air into the housing (231) through the filtering panel (220) via the second intake port (231-1), and to discharge sterilized air to the outside of the housing (231) via the second discharge port (231-2).

Additionally, multiple fan units (237) may be provided as needed.

For example, the fan unit (237) may be provided in multiple units corresponding to the left-right width or up-down height of the path through which air flows.

In this embodiment, two fan units (237) are provided on the left and right.

In addition, as shown in FIG. 12, the sterilization module (230) may be provided with a second filtering member (238) that is arranged at a distance from the rear of the light source unit (233) and is composed of a pre-filter, a HEPA filter, or a carbon filter to re-purify the air purified by the purification and sterilization module (200). In this case, it is also possible to use a combination of two or more filter elements.

The above second filtering member (238) is spaced apart from the rear of the photocatalytic filter (232) and the light source unit (233) described above, so that air can be pre-filtered in a stage before the photocatalytic filter (232) and the light source unit (233).

That is, the second filtering member (238) may have a plate shape that divides the entire interior of the housing (231) into front and back sections so as to correspond to the aforementioned photocatalytic filter (232) or light source unit (233), and may be supported on the inner wall of the housing (231) and fixed at a predetermined position inside the housing (231).

In the present embodiment, the second filtering member (238) is exemplified as having a generally square plate shape to correspond to the photocatalytic filter (232), etc., but may be modified in various ways to correspond to the shape of the housing (231), etc., and is not necessarily limited to what is exemplified.

The above smart control unit (240), as shown in Fig. 3, is fixed to the bottom of the main body (210) with screws, etc., and performs the functions of CCTV video recording (black box), emotional lighting, and purified air sterilization on/off according to the human body detection signal of the IrDA (Infrared Data Association) infrared sensing unit.

The sensor built into the above smart control unit (240) detects the indoor or surrounding air quality in four stages: very dangerous, dangerous, normal, and clean, and displays the detected information in the form of an OSD (On Screen Display) on the image information of the camera (100).

That is, before or when the air purified and sterilized through the purification and sterilization module (200) is discharged, the air condition inside the main body (210) is displayed as a light or image through the smart control unit (240).

Here, the air pollution index is controlled to be displayed in stages, preferably in three stages, through the air purification display unit (215) using set color lighting according to the fine dust concentration sensed by the air purification and sensing unit in the smart control unit (240).

For example, the air pollution index detected through the sensing unit of the smart control unit (240) is displayed in red before purification, yellow after purification, and blue after sterilization through the air purification display unit (215).

Accordingly, through the smart control unit (240), when the air quality suddenly deteriorates due to external inflow of air or occurrence of abnormal symptoms, it is possible to control the fan unit (237) of the sterilization module (230) to operate and introduce contaminated air into the purification and sterilization module (200) so that the air quality can be improved within a short period of time.

Hereinafter, the operation process of a photographing device equipped with a camera (100), a black box (not shown), an air purification and sterilization module (200), and an air pollutant purification device having an air purification display unit (215) function according to the present invention will be briefly described.

First, the purification and sterilization module (200) combined with the camera (100) is installed on a fixed body (not shown) such as a wall.

Next, the fan unit (237) is driven according to the control signal of the smart control unit (240), so that the contaminated air is introduced into the internal space of the main body (210) through the first intake port (211).

Next, the polluted air drawn in through the first intake port (211) is purified through the filtering panel (220), while at the same time, fine dust is sensed through a sensing device (not shown) provided in the smart control unit (240).

Next, the purified air is moved to the sterilization module (230) through the second suction port (231-1) by the operation of the fan unit (237).

Here, before the purified air moves to the sterilization module (230), it is also possible to purify it again through the second filtering member (238).

Then, the purified air is sterilized by irradiating UV-A rays (ultraviolet rays) through the light source unit (233) to the photocatalytic filter (232).

Then, the sterilized air is discharged into the main body through the second exhaust port (231-2).

At this time, the sterilized air is detected by the sensing unit of the smart control unit (240), and at the same time, the air purification display unit (215) is displayed in blue.

Next, the sterilized air is discharged to the outside through the first discharge port (212) of the main body (210).

And, the IrDA infrared sensing unit detects human body movements and transmits them to the smart control unit (240).

At this time, the smart control unit can also perform CCTV video recording (black box), emotional lighting, and air purification On/Off functions according to the human body detection signal of the IrDA (Infrared Data Association) infrared sensing unit.

Next, the camera (100) is operated to capture video of the indoor space.
