Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bubble supply device used in a fish tank or the like.

[0002]

[Prior Art]

 The conventional bubble supply device only supplies air into water with an air pump. It is then filtered to keep the water clean. However, since the amount of bubbles is small, the fish gather at the outlet of the bubbles and always open their mouths to breathe.

[0003]

[Problems to be solved by the device]

 It is an object of the present invention to provide a supply device capable of supplying sufficient air bubbles according to the number and size of fish in an aquarium so that the amount of air bubbles generated can be adjusted.

[0004]

[Means for Solving the Problems]

 The above object is to provide an L-shaped conduit having one water suction port and two water suction ports, means for controlling the generation of negative pressure by controlling the amount of water flowing into one water suction port, And a means for controlling the amount of air introduced into water by pressure, which is solved by an elbow structure for a bubble supply device.

【Example】

 A preferred embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2, reference numeral (10) indicates an elbow body. The elbow body (10) has a pipe mounting port (12), that is, a discharge port communicating with the water intake port, a first water suction port (13) facing the mounting port (12), a mounting port (12) and a first port. An L-shaped water passage formed by a vertical passage extending vertically upward from a horizontal passage connecting to the water suction inlet (13) to reach the second water suction inlet (11), and a lead extending horizontally adjacent to the vertical passage. A screw rod guide hole, a small-diameter through hole (14) formed in the upper end of the lead screw rod guide hole (smaller than the guide hole), an air flow pipe extending parallel to and adjacent to the lead screw rod guide hole, The air inlet (15) and the screw part (151) formed on the upper end of the flow pipe, the vertical recessed groove (152) formed on the screw part (151), and the fitting formed on the lower end of the air flow pipe. It is composed of a joint part (153).

Reference numeral (31) is an air adjusting screw, which has a protruding ring (310) on its inner upper end surface and an internal thread on its inner side, and engages with a screwing portion (151). (Fig. 5) When the protruding ring (310) and the vertical recessed groove (152) are brought into close contact with each other by turning the air adjusting screw (31), air does not flow from the outside. According to the above, air can flow in.

An air conduit (32) is engaged with the fitting portion (153), and air is sucked in through the air conduit (32).

The upper end of the lead screw rod (21) projects upward through a through hole (14) formed in the upper end of the guide hole, and a turning screw (23) is screwed in. There is a flange just below the upper end of the lead screw rod (21) and it abuts on the upper end of the guide hole. Below the flange there is a male thread. This male screw part is screwed into the screw hole of the adjusting plate (22).

A fitting rail groove (44) for guiding the vertical movement of the adjusting plate (22), a through hole (42) for receiving and supporting the lower end of the air conduit (32), and a first water intake port An inverted L-shaped stopper plate lid (40) having a through hole (43) arranged so as to face the (13) is provided.

[Action and effect]

 When the above elbow structure is placed in the water tank and the water suction pump (not shown) is driven, water flows in through the second water suction port (11) and the pipe mounting port (12), that is, the water discharge port (12). ) To the pump. At this time, water is also sucked from the first water suction port (13) through the through hole (43) and sent to the pump. The amount of the water can be adjusted by the adjusting plate (22) which is interposed between the through hole (43) and the first water intake port (13) and moved up and down along the fitting rail groove (44). .. The adjustment is done by turning the screw (23). Since water flows into the first water suction port (13), a negative pressure is generated near the lower end of the air conduit (32), so that air is introduced from the air intake port (15) to generate bubbles. The amount of air bubbles is adjusted by turning the air adjustment screw, and when it is completely closed, the protruding ring (310) (see FIG. 5) blocks the upper end of the vertical recessed groove (152) (see FIG. 2) to allow air to flow. It will not enter, and a large amount of air will be able to flow in as it opens.

In addition to the generation of bubbles, the pump is driven to circulate the water in the water tank to cause convection and make the temperature distribution uniform. Furthermore, a filtration device can be provided in the circulation path. Blocking the second water inlet (11) increases the amount of intake from the first water inlet (13).
