Abstract

The utility model relates to a composite-casing type air pump, in particular to the air pump with a shockproof and noise-reduction function, comprising a top head, a base, a seat tray and at least a group of air pump units; wherein the top head and the base are double-casing structures with the inner casing and the external casing, which are cooperated with the base plate to provide the air pumps for sending out air. The air passes through a connecting hose, turns to a side gas chamber, flows together in a collecting chamber and is exhausted through an exhaust tube, which provides the needed air for the aquarium.

Description

The double hull type air pump

Technical field

The utility model relates to a kind of double hull type air pump, particularly be a kind of have that against shock reduces the noise function supply the air pump of air for aquarium.

Background technique

The general Shui nationality mainly are to provide the aquarium aquaculture organism required oxygen with air pump, utilize the compression of its inner air pump unit, to produce air-breathing and the exhaust start, because alternately bouncing at a high speed can be sent harsh noise, influence peacefulness at home, therefore industry is actively sought the road that solves, wherein, number as the tw Taiwan patent announcement: 519194,416488 cases (hereinafter to be referred as preceding case), promptly utilize air pump unit one side to be equipped with some discharge chambers that add large volume, with a noise reduction air chamber structure of forming, solve noise problem by this.

Above-mentioned existing preceding case, though can reduce the volume of noise, the following defective of so deriving:

1. air pump unit such as desire improve its air output, must adopt bigger horsepower, and the horsepower one big noise that produces improves thereupon, depends merely on the noise-reducing structure of discharge chamber, can't effectively reduce the problem that noise exists at all.

2. the horsepower of air pump unit promotes, and the vibrations of thing followed casing are rocked, and more because of the shake phenomenon, instead deepens the degree that noise is disturbed the people.

Summary of the invention

The purpose of this utility model: a kind of air pump that has against shock and reduce noise is provided.

Be the technological scheme that realizes that this purpose adopts: this air pump is to include a loam cake, a base, an attic base and at least one group of above air pump unit, it is characterized in that this loam cake and base are the double-layer shell structures with inside and outside shell, cooperate this attic base to provide the air pump unit to send air, after entering a side air chamber via connecting tube turnover, conflux behind a collection chamber, discharge from an outlet pipe again,, effectively solve the problem of noise and vibrations by with the required air of supply aquarium.

Below in conjunction with accompanying drawing, to this novel above-mentionedly is described in more detail with other technical characteristics and advantage.
