[Industrial applications]

 The present invention relates to a carbon dioxide diffusing device in a water tank for growing aquatic plants, in which a supply pipe for feeding carbon dioxide into the water tank is provided with a diffuser for diffusing the carbon dioxide in a foam state.

[0002]

[Prior art]

 Generally, terrestrial plants have the advantage that carbon dioxide in the atmosphere can be freely consumed during the process of photosynthesis. However, when growing aquatic plants in a closed environment within the aquarium, the limited amount of carbon dioxide contained in the water in the aquarium is immediately absorbed by photosynthesis, so carbon dioxide is constantly produced from outside. Must be invested in. For this reason, a supply pipe is connected to a cylinder as a carbon dioxide supply source, a predetermined amount of carbon dioxide is appropriately charged into the water tank, and carbon dioxide is submerged in water by a diffuser provided in the middle of the supply pipe. A carbon dioxide diffusing device has been conventionally known that can obtain an ideal pH value suitable for growth of aquatic plants by facilitating the carbon dioxide to dissolve in the water in the aquarium by diffusing into bubbles. There is.

[Problems to be solved by the device]

 In the above-mentioned prior art, a porous filter for diffusing carbon dioxide into bubbles is provided inside the diffuser, but the filter is generally composed of a so-called cotton-like member such as atomizer stone. Therefore, it is impossible to finely bubble carbon dioxide into a size large enough to dissolve in water. For this reason, problems such as the need to supply carbon dioxide more than necessary and the lack of the amount of carbon dioxide that dissolves in water were not being able to provide an ideal environment for aquatic plants.

The present invention is intended to solve such problems, and provides a carbon dioxide diffusing device in an aquatic plant growing water tank capable of efficiently dissolving carbon dioxide in water in the water tank. The purpose is to

The diffuser 12 adsorbed on one side surface of the is provided in a state of being submerged in water.

As shown in FIG. 2, the diffuser 12 has a glass-made connecting portion 13 which can be fitted into the tip of the supply pipe 9, and a substantially cylindrical body which is integrally formed with the connecting portion 13 and communicates with the supply pipe 9. A section 14 and a disk-shaped porous filter 15 made of glass and provided inside the main body section 14 are provided. Further, a mounting portion 16 having a spherical tip is formed on one side of the main body portion 14, and a recess 17 formed at the base end of the suction cup 11 is fitted into the mounting portion 16. Further, an opening 18 is formed at the upper end of the main body portion 15, and the foamy carbon dioxide that has passed through the filter 15 is diffused from the opening 18 into the water tank 1. Further, as shown in FIG. 3, the flowmeter 10 from the cylinder 6 is formed so as to communicate between the connecting portion 21 made of glass into which the supply pipe 9 is fitted and the connecting portion 21 and has a diameter larger than that of the connecting portion 21. It has a large cylindrical shape and is provided on the supply path 19 to the porous filter 15 as a water containing portion for containing the water A, and at the lower end of the flow measuring portion 22 at the upper end of one connecting portion 21.

In the water tank 1, a porous filter 15 made of glass having a structure having a smaller pore size than that of the conventional cotton-like member is disposed in the portion, and the carbon dioxide sent through the supply pipe 9 is passed by the filter 15. The carbon dioxide can be finely foamed to a size such that it can be sufficiently dissolved in the water A. Therefore, even if carbon dioxide is not supplied more than necessary from the cylinder 6, carbon dioxide can be efficiently supplied to the entire aquatic plant 4, and an ideal environment for the aquatic plant 4 can be obtained.

In addition, the present embodiment corresponds to claim 2, and a substantially cylindrical main body portion 14 on which the porous filter 15 is mounted, and a water tank 1 which is provided on one side of the main body portion 14 and can be adsorbed Since the diffuser 12 is constituted by the suction cup 11, it is possible to easily attach the diffuser 12 to a predetermined position in the water tub 1 simply by adsorbing the suction cup 11 to the side portion of the water tub 1.
