る。B. Conventional technology Methods to increase the amount of dissolved oxygen in water include creating contact between water and air using fountains or making waves on the water surface, or using an air pump to pump air into the water to create air bubbles. There is a means to form
-As disclosed in Publication No. 13314, there is also a technology that uses a device that simultaneously sucks water and air and discharges water mixed with air, and furthermore, a submersible aerator that introduces air into the sucked water. Are known.

ると話は違つてくる。C. Problems that the invention aims to solve Conventional devices function as bubble generators that absorb oxygen from the air into water and increase the amount of dissolved oxygen, although the amount of air taken in varies greatly.
In particular, the story is different when it comes to bubble generators used for hydroponic cultivation.

を招く。 In other words, conventional devices are used to raise fish and shellfish in aquariums, or to stir and absorb gases through reaction, so in the former case, the distribution of dissolved oxygen in the tank is Even if they are heterogeneous, fish and shellfish can be moved to any desired location, and in the latter case, consideration for the survival of the organisms is not considered from the beginning. Therefore, even if they are used in a hydroponic cultivation device that grows plants that are supported in a fixed position and placed in a state where the thin water roots are placed in a state where they appear to be floating in the water, dissolved water will not be present between the entangled water roots. Water with high oxygen content,
It is impossible to expect the water to pass through evenly with a slow flow, and if the discharge rate is reduced, anaerobic bacteria will multiply in the water and cause diseases such as rotting plant roots. If the agitation efficiency is increased, the water current will damage the roots and cause them to die.

を特徴としている。D. Means to solve the problem Therefore, the present invention provides an air bubble generator that has an extremely simple configuration and is ideal for hydroponic cultivation, thereby ensuring a uniform amount of dissolved oxygen in the water while taking care to protect the water roots. This system aims to improve the growth of plants by increasing water flow from the inlet to the outlet by installing an impeller that is rotated by a built-in motor in the flow path that communicates the inlet and outlet. A submersible pump that sends water to
a suction pipe that protrudes from the suction port of the submersible pump and has a first water suction adjustment hole bored on the outer periphery of the tip;
Rotatably fits into the tip of the suction pipe,
A water supply amount adjustment cap having a second water absorption adjustment hole at an outer peripheral position corresponding to the first water absorption adjustment hole is connected between the impeller of the suction pipe and the first water absorption adjustment hole, and is open to the atmosphere. The submersible pump is characterized by comprising an air introduction pipe having a regulating valve at the air intake, and a discharge pipe connected to the submersible pump discharge port and having aerated water jet ports bored at equal intervals in the longitudinal direction.

なつてよどみなく分散される。E. Effect: If the discharge pipe is placed along the side of the bottom of the cultivation tank and the submersible pump is started, water will be sucked from the water suction hole of the suction pipe, and
As the inside of the suction pipe becomes negative pressure, air from the atmosphere is sucked through the air introduction tube attached to the outer circumference of the suction pipe, and the sucked air is stirred by the rotation of the impeller inside the submersible pump. After being mixed and stirred, the bubbles collide with each other as they pass through the corners provided in the pump, becoming finer bubbles and mixing with the water, and are evenly distributed over a wide area as a gas-liquid mixed fluid from multiple spout ports. The ejected water is dispersed smoothly into the cultivation tank with a gentle flow.

Effects of the invention As described above, according to the invention, air is introduced, the air is mixed with the discharged water, and the water containing a large amount of air is jetted from the spout hole into the cultivation tank. This increases the amount of dissolved oxygen in the water in the cultivation tank. However, since the gushing water flows out from a large number of spout holes provided along the length of the discharge pipe, the flow is gentle and gradually permeates throughout the tank in a band-like manner, and it flows between the thin water roots that are intertwined with each other. It reaches every nook and cranny of the plant and achieves oxygen supply without damaging the roots. Such air supply conditions can be said to be the best environment for hydroponic cultivation. Furthermore, since the amount of water and air can be increased or decreased, adjustments can be made depending on the scale of the cultivation tank and the type of plants.
