Description

Pump room of air pump

The present invention relates to an air pump for supplying oxygen from an aquarium or a septic tank, and more particularly, a permanent magnet holder vibrates in a horizontal direction by a generating magnetic field of an electric vibrator in the air pump, where a pumping action is performed. It is about the pump room of the air pump.

Generally, in order to decorate the beauty of the interior aesthetically and vividly in homes, offices and other places, there is an aquarium where various fish can swim and play. The fish swimming and playing in the aquarium have food to be paid separately. In order to maintain life by breathing oxygen contained in the aquarium, an air pump that generates air separately is widely used in popularity.

As such, recently used air pumps change the polarity a number of times due to the flow of electricity in a case separated up and down, and the adjacent permanent magnet holder is vibrated by the alternating alternating electromagnetic force due to the changed polarity. By operating the diaphragm of the pumping action, the suction and discharge from the pump room is forced to supply air into the aquarium.

Here, the conventional air pump 1 and the pump chamber 10 will be briefly described with reference to FIGS. 1 to 2 as follows.

First, the air pump (1) is composed of a case (2) and the body portion (3) the outer periphery, the support plate (4) is fixed to the top of the body portion (3) and the electric vibrator (5) is provided on both sides inside The permanent magnet holder 6 is positioned between the electric vibrators 5 and the front end thereof is coupled to the diaphragm 40 of the pump chamber 10 fixedly attached to both sides of the support plate 4.

The pump chamber 10 has an inner case 20 fitted into both insertion holes 4a of the support plate 4, and the inner case 20 has a groove 20a formed at one side thereof and an air inlet ( 21 is drilled, and the groove 20a is fitted with an edge portion of the diaphragm 40, and the center of the diaphragm 40 and one side of the spiral shaft 6a of the permanent magnet holder 6 are connected to the diaphragm fixing portion 50. The outer case 30 having the suction chamber 31 and the discharge chamber 32 is coupled to the inner case 20 so as to be firmly fixed to the support plate 4 by a bolt 60. .

However, in the conventional pump chamber 10 as described above, the outside air is introduced into the case 2 through the inlet of the upper end of the case 2 and enters the pump chamber 10 through the air inlet 21. Since the air inlet 21 is provided to be biased to one side, there is a problem that the cooling efficiency of the electric vibrator 5 which generates much heat due to the air flow is biased to only one side.

In addition, the diaphragm 40 also causes the permanent magnet holder 6 to reciprocate at a high speed to perform a pumping action, thereby rapidly generating contraction and expansion, thereby generating a lot of heat. However, there is no cooling means, and thus the life of the diaphragm 40 is long. There is also a problem that is shortened.

The object of the present invention for solving the conventional problems as described above, the air flow is always provided by integrally provided in the diaphragm fixing part fixed to the center of the diaphragm installed in the pump chamber and the conventional air inlet and the suction side biased to one side It is to provide a pump chamber to flow to the center to increase the cooling efficiency of the electric vibrator and the diaphragm.

Still another object is to provide a pump chamber in which a plurality of grooves are zigzag-formed on both sides of the diaphragm to increase the elongation to increase the pumping efficiency and to increase the surface area to further increase the cooling efficiency of the diaphragm.
