Description

The present invention covers the ultraviolet germicidal lamp used for household ornamental water tanks to prevent the diffusion of ultraviolet rays, and irradiates the water in the water tank circulated inside the cover with the ultraviolet rays of the ultraviolet germicidal lamp by the air lift method using an air pump. Regarding the cover of UV germicidal lamps that are sterilized and purified.

Ultraviolet sterilization equipment is very effective in purifying aquarium water in household ornamental aquariums. Microorganisms such as moss spores that are hated and germs that cause unpleasant odors can be quickly extinguished. Until now, the ultraviolet sterilization equipment used for household ornamental water tanks has generally been an internally illuminated type with a water passage and a germicidal lamp built in a closed housing. (Refer to Non-Patent Document 1) In this method, the water tank water is circulated in the water passage inside the housing by an attached or external motor, and the water in the water tank is sterilized by irradiating the ultraviolet rays of the germicidal lamp at any part of the water passage. It is a structure to do. On the other hand, there was also an externally illuminated UV sterilizer that did not have a housing that included the waterway. However, if this is installed in an aquarium, harmful ultraviolet rays will adversely affect the viewers and the living organisms they raise. In addition, when installed in the aquarium water filter tank, the bactericidal effect of ultraviolet rays reduces even the filtered microorganisms that are useful for purifying the aquarium water, so there was no suitable installation location. Therefore, externally illuminated UV sterilizers are not widely used. In addition, there was no cover that would enable the use of externally illuminated UV germicidal lamps safely and efficiently.

The internally illuminated UV sterilizer used in household ornamental water tanks packs waterways, motors, sterilizer chambers, etc. inside a sealed housing, which makes the equipment complicated and large, but the large size of the germicidal lamp to be installed. It was difficult to sterilize. For the separate motor type, it was necessary to prepare a separate motor device. As a result, many products are costly, difficult to maintain, and have a relatively low bactericidal effect.

Externally illuminated UV sterilization equipment is dangerous for UV rays that are harmful to humans and pets, and it sterilizes both germs and beneficial filtered bacteria without distinction. , There was no suitable installation location. The present invention has been made to solve these problems.

A cover for UV germicidal lamps used to purify the water quality of household ornamental aquariums.
The cover is made of a material having an ultraviolet transmittance property that does not substantially transmit the ultraviolet rays emitted by the ultraviolet germicidal lamp in the product state.
The main structure is a box-shaped body having an internal space that can store at least the light emitting part of the ultraviolet germicidal lamp while securing a water passage around the ultraviolet germicidal lamp.
The box-shaped body has an ultraviolet germicidal lamp through port, an air supply pipe connection port, and an intake port and an outlet for water in a water tank as openings.
The water passage is a space that is secured inside the box-shaped body and communicates from the intake port to the discharge port with the ultraviolet germicidal lamp stored in the box-shaped body.
The air supply pipe connection port is provided in the box shape so as to open toward the outside of the cover from any position of the water passage from the intake port to the discharge port.
The box-shaped body is provided with an irradiation chamber and an air lift tube.
The irradiation chamber is a part of the box-shaped body that houses and surrounds the light emitting part of the ultraviolet germicidal lamp at any position of the water passage from the intake port to the air supply pipe connection port, and circulates in the water passage. It is a chamber-like part for irradiating the water in the water tank with the ultraviolet rays of the ultraviolet germicidal lamp.
The air lift pipe is a part of the box-shaped body that extends from the air supply pipe connection port to the discharge port, and is a narrow tubular part that produces an air lift effect that circulates water in the aquarium in the water passage.
The UV germicidal lamp has at least its light emitting part housed in a box shape and is connected to an external power source through the UV germicidal lamp through port.
An air supply pipe is connected to the air supply pipe connection port from the outside, and due to the air lift effect of the air supplied from the air supply pipe, the aquarium water is taken in from the intake port and discharged from the discharge port through the water passage.
The water quality of a household ornamental water tank that sterilizes the water in the water tank by irradiating the water in the water tank circulated inside the box with the ultraviolet rays of an ultraviolet germicidal lamp and blocks the irradiation of the ultraviolet rays to the outside of the cover. Create a cover for UV germicidal lamps used for purification.

The box-shaped body is provided with an opening / closing mechanism and a boundary bending portion.
The opening / closing mechanism is a part where the box-shaped body has the opening / closing function of the housing.
The boundary bending portion is provided at the boundary between the irradiation chamber and its external space in the box-shaped body.
Bending, which is formed by a box-shaped housing or inner wall structure that bends the boundary space so as to prevent the internal space and the external space of the irradiation chamber from being connected by a straight line at the boundary. It ’s a tubular part,
The internal space and the external space of the irradiation chamber communicate with each other through the boundary bend, and at the same time.
Due to the bending of the space formed by the boundary bending portion provided in the boundary region, the ultraviolet rays emitted from the ultraviolet germicidal lamp contained in the internal space of the irradiation chamber hit the boundary bending portion and are blocked and leaked to the external space. To prevent this, create a cover for the UV germicidal lamp used to purify the water quality of the separated household ornamental water tank.

When the present invention is used together with an ultraviolet germicidal lamp and an air pump, the leakage of harmful ultraviolet rays can be prevented equally by the box-shaped body of the present invention and the boundary bending portion as compared with the closed type internally illuminated ultraviolet sterilizing device equipped with a motor. It can be done, but the structure is simple and the equipment cost is low.

Since the air lift type is used to power the water circulation, the running cost is lower than the electric pump type used in many internally illuminated UV sterilizers.

Unlike the closed type housing, maintenance such as cleaning the inside and replacing the germicidal lamp is easy, and as a result, the product life is extended, the sterilizing effect is enhanced, and the maintenance cost is low.

Since it has a simple box shape and can be used for germicidal lamps of various sizes and shapes, a strong germicidal effect can be obtained by using a high-power germicidal lamp that has not been commercialized as an internally illuminated UV germicidal lamp. This is also easy to achieve at low cost.

There was a danger of harmful ultraviolet rays when using an externally illuminated ultraviolet sterilizer alone in a household ornamental water tank facility, but when installed in the water tank using the present invention, the cover and opening that do not transmit ultraviolet rays The boundary bend prevents the leakage of ultraviolet rays and is safe for humans and pets. Even if it is installed in the filter tank, it does not sterilize the beneficial filtering bacteria in the filter medium.

Since the present invention is provided with a water circulation mechanism by an air lift, the entire aquarium water can be sterilized and purified when installed in the aquarium. By adjusting the air supply amount and the air lift effect, it is possible to optimize the intake water amount with respect to the output of the germicidal lamp and efficiently sterilize and purify the aquarium water.
