Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air diffusing tube using a natural wood diffusing material, and more particularly to an aerating tube for a water tank for generating bubbles in water to supply dissolved oxygen in the water,
Regarding air diffuser as adsorption / filter material.

[0002]

2. Description of the Related Art An air diffuser for dispersing gas around is used, for example, as an aquarium for ornamental fish such as goldfish and tropical fish, an aquarium for transporting live fish, a general aquarium, and an adsorption / filter material.

Particularly, in the aquarium for ornamental fish for general households and the aquarium for transporting small live fish, it is important to control the dissolved oxygen consumed as well as the water temperature control, and oxygen or air cannot be constantly replenished sufficiently. must not. At this time, the dissolved oxygen is usually supplied by an inorganic natural or artificially processed mineral such as burnt stone, air stone, or ceramics, and an air diffuser using a recent foamed organic polymer system.

[0004]

However, the dissolved oxygen dissolved in the water tank is limited by temperature and pH,
Since it is difficult to dissolve more than the saturation amount and it is consumed by fish in the aquarium, it is necessary to constantly supply oxygen gas, and more effectively the bubble size of the supplied oxygen gas, the diffusion position, etc. The amount of oxygen dissolved in is drastically changed. The conventional air diffuser cannot necessarily obtain an effective bubble size, and since it uses an artificial material, there is a fear that impurities that adversely affect the living body may be mixed in water.

The present invention has been made on the basis of the above-mentioned background, and an object thereof is to generate an effective bubble size, and to prevent the inclusion of impurities that adversely affect the living body due to artificial materials. Is to provide a proper air diffuser.

[0006]

The present invention solves the above problems. That is, the air diffuser according to the present invention has 10 to 10
The present invention is characterized by using a natural wood pore material having a 200 μ conduit or a temporary conduit.

In a preferred embodiment of the present invention, maple wood, poplar wood, cherry wood, and beech wood can be used as the natural wood.

In another more preferable aspect of the present invention, an air diffuser for generating bubbles in water to supply dissolved oxygen in water can be used.

In another preferred aspect of the present invention, the air diffuser has a conical outer shape, and a space communicating with the supply port for the predetermined gas is formed inside the air diffuser. it can.

In still another aspect, the air diffuser may have an outer shape of a dome shape, and a space communicating with a supply port for a predetermined gas is formed inside the air diffuser.

In another aspect of the present invention, it may be an air diffuser used as an adsorption / filter.

[0012]

According to the present invention having the above-mentioned structure, it operates as follows. In the present invention, since a natural wood pore material having a conduit or a temporary conduit of 10 to 200 μ is used, a gas that permeates through a conduit or a temporary conduit having a fine and complicated shape and a tube wall formed of natural woody cellulose. Is transparent. The permeated gas comes into contact with the wall of the tube having a large surface area, and is adsorbed or reacted with harmful chemical substances, fine particles, bacteria, etc. to be removed. Further, since a substantially uniform conduit or temporary conduit having a tube diameter of 10 to 200 μ is provided, fine bubbles can be generated. Particularly preferable bubble generation occurs in the natural wood maple wood, poplar wood, cherry wood, and beech wood used in the preferred embodiment of the present invention.

[0013]

EXAMPLES The present invention will be described with reference to more specific examples. The pore-forming material used in the present invention has through-hole / porosity, and is specifically natural wood having a conduit or temporary conduit of 10 to 200 μm. For example, maple wood,
Poplar wood, cherry wood, beech wood, and more preferably
It is a maple material.

Evaluation Example 1 From a poplar material having a conduit of 15 to 65 μm or a temporary conduit,
Prototypes of air diffusers each having a space of 20 mm × 20 mm × 40 mm formed by punching holes were formed. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of fine bubbles were generated from the wood opening of the poplar material, which is a pore-forming material, even at low pressure, and they were stably and continuously generated. However, it did not occur from the entire surface of the mouth and was partial. The overall evaluation was good.

Evaluation Example 2 From a cherry tree material having a conduit or temporary conduit of 10 to 80 μ,
Prototypes of air diffusers each having a space of 20 mm × 20 mm × 40 mm formed by punching holes were formed. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of fine bubbles were generated from the mouth of the cherry tree material, which is a pore-forming material, even at low pressure, and stable and continuous medium-sized bubbles were generated. At this time, the outbreak occurred from the entire surface of the mouth. The overall evaluation was good.

Evaluation Example 3 From a walnut material having a conduit of 20 to 350 μm or a temporary conduit, a diffuser tube having 20 mm × 20 mm × 40 mm square wood was punched to form an internal space. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of fine bubbles were generated from the mouth of the walnut wood, which is a pore-forming material, even at low pressure, and they were stably and continuously generated at relatively high pressure. However, it was generated at high pressure from the mouth side as a whole, and the comprehensive evaluation was normal.

Evaluation Example 4 From a beech material having a conduit of 10 to 95 μ or a temporary conduit, 2
Prototypes of each air diffusing tube in which an internal space was formed by making a hole in a square material of 0 mm × 20 mm × 40 mm. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of fine bubbles were generated at the mouth of the beech wood, which is a perforation material, even at low pressure, and the foam was stably and continuously generated. At this time, the outbreak occurred from the entire surface of the mouth. The overall evaluation was good.

Evaluation Example 5 From a maple material having a conduit of 15 to 105 μm or a temporary conduit, a diffuser tube having a 20 mm × 20 mm × 40 mm square bar was punched to form an internal space. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of fine bubbles were generated from the mouth of the maple tree, which is a pore-forming material, even under a low pressure, and the fine bubbles were stably and continuously generated. At this time, the outbreak occurred from the entire surface of the mouth. The overall evaluation was particularly good.

Evaluation Example 6 Diffuser tubes each having an internal space formed by punching a square material of 20 mm × 20 mm × 40 mm from an Apiton material having a conduit or a temporary conduit of 260 to 330 μ were manufactured. An air pump was connected to this air diffuser via a tube and placed in a water tank to evaluate the foaming condition. As a result, a large number of medium bubbles were continuously generated from the mouth of the Apiton material, which is a pore-forming material, even at low pressure. The overall evaluation was normal.

Evaluation Example 7 An air pump was connected to an air diffusing tube of a commercially available air stone for goldfish via a tube and placed in a water tank to evaluate the foaming condition. As a result, from this air stone, large bubbles were generated moderately even at low pressure, and large bubbles were continuously generated.
The overall evaluation was normal. From the above evaluation of the material of the air diffuser, it is understood that natural wood having a conduit or temporary conduit of 10 to 200 μ according to the present invention, that is, maple wood, poplar wood, cherry wood and beech wood is preferable.
