In the existing diaphragm air pump, an air outlet check valve plate needs to be installed on an air outlet channel of a valve seat, the air outlet channel on the valve seat is closed by the air outlet check valve plate in an air suction stage of the air pump, and the air outlet channel on the valve seat is opened in an air exhaust stage of the air pump, but the air outlet check valve plate occupies a part of the cross section of the air outlet channel of the valve seat, so that the output of air flow is blocked, and the air outlet pressure is reduced; on the other hand, the manufacturing cost of the whole air pump is difficult to reduce due to the higher cost of the air outlet check valve plate; for example, patent application No. 201020263735.0 discloses a diaphragm air pump, including "pump casing, motor, disk seat, top cap, the motor dress is on a terminal surface of pump casing, and disk seat, top cap are adorned in proper order on another terminal surface of pump casing, are equipped with in the pump casing and link assembly and the elastic diaphragm that link assembly and link assembly are connected that connects the visitor to produce reciprocating motion with the motor, are provided with between disk seat and the top cap and admit air and give vent to anger check valve piece, its characterized in that: the air inlet and outlet check valve plate is of a dumbbell-shaped structure, and a sealing ring is arranged between the valve seat and the top cover. "in this patent, the air suction passage is short, and the noise of the air flow during air suction is easy to be transmitted, so the noise is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a structure of making an uproar falls in being used for the diaphragm pump can effectively solve the too big weak point of above-mentioned valve block vibration production noise.
The utility model discloses a following technical scheme realizes:
a structure for noise reduction of a diaphragm pump, comprising: pump casing, motor, valve hypoplastron, valve upper plate, cavity, air inlet valve block, play gas valve block, the motor is fixed in the pump casing side, and pump casing upper end is fixed with the valve hypoplastron, and the valve hypoplastron is fixed with the valve upper plate, sets up the cavity between valve hypoplastron and the valve upper plate, is provided with air inlet valve block, play gas valve block, its characterized in that between valve hypoplastron and the valve upper plate: a sound dampening material within the cavity.
Preferably, the valve upper plate and the valve lower plate are rectangular parallelepipeds.
Preferably, the cavity between the valve upper plate and the valve lower plate is rectangular.
Preferably, 4 fixing legs are arranged below the pump housing, and each fixing leg is Z-shaped.
Preferably, the 4 fixing feet are X-shaped, and each fixing foot is provided with a screw hole.
The beneficial effects of the utility model reside in that:
the utility model relates to a rationally, through set up the amortization material in the cavity for the noise that the valve block that admits air and the valve block vibration of giving vent to anger produced reduces, and the rethread lengthens the length of valve upper plate and valve hypoplastron, thereby lengthens the cotton volume of amortization of cavity length increase, noise abatement once more.
