Abstract
The utility model relates to a kind of air pump that improves noise elimination air intake structure, comprise casing, air chamber, pad and base plate, the suction port of described air pump is opened on base plate, described base plate inner side is provided with gas muffler lid, described gas muffler is covered with the noise elimination gas-entered passageway that a port is connected with suction port, and pad bottom is led in described noise elimination gas-entered passageway another port.During work: the gas sucking from suction port first, after noise elimination gas-entered passageway, enters the pad bottom in air pump, enters air chamber after pad filters out dust again.The utility model has improved suction port position and has installed gas muffler lid additional, overcomes that original air pump noise is large, suction port is easily piled up the shortcomings such as dust, makes existing air pump more perfect; With equal air pump contrast, operating noise declines 7 ~ 8 decibels, original 55 decibels of left and right, existing 47 decibels of left and right; Dust from gas is difficult for entering air chamber, has improved quality and working life; The gas-entered passageway of gas increases, and can arbitrarily regulate air-flow size.
Description
Technical field
The utility model relates to a kind of air pump that improves noise elimination air intake structure, is specially adapted to the air pump of small-sized 2 air chambers.
Background technique
As shown in Figure 1 and 2, original pair of air chamber air pump construction is around upper enameled wire loop by two mountain shaped iron cores 3, be fixed on the interior left and right of air pump casing 1 end (laterally), after energize, produce magnetic field, the swing frame 4 that drives two iron cores 3 middle (longitudinally) to stud with both positive and negative polarity magnet is done swing, and then drive two pairs of rubber cups 5 to do back and forth to stretch to suck gas, and through valve sheet 6, control after intake and exhaust amount, produce air-flow and air pressure.
The noise sound source discharge route that the 10 positions designs of its suction port produce when total enclosure 1 top one diameter 2.6mm aperture is done gas-entered passageway and air pump internal pendulum moving frame 4, rubber cup 5, valve sheet 6 work.These suction port 10 designs, because passage is short, directly cannot reduce intake and exhaust sound source, exist again and easily pile up the shortcomings such as dust that suck in gas.
Model utility content
The problem that the utility model exists for above-mentioned prior art is made improvement, be that technical problem to be solved in the utility model is to provide a kind of air pump that improves noise elimination air intake structure, overcome the difficult problem that original air pump gas dust accretion, noise sound source cannot reduce, made air pump more perfect.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of air pump that improves noise elimination air intake structure, comprise casing, air chamber, pad and base plate, the suction port of described air pump is opened on base plate, described base plate inner side is provided with gas muffler lid, in described gas muffler lid, be provided with the noise elimination gas-entered passageway that one end is connected with suction port, the described noise elimination gas-entered passageway the other end leads to pad bottom.
Preferably, described suction port is the aperture of diameter 6.8mm.
Preferably, described noise elimination gas-entered passageway twist.
Preferably, it is inner that described noise elimination gas-entered passageway is arranged at gas muffler lid.
Preferably, described gas muffler lid is to offer spiral fluted dome, between described spiral chute and the inner side surface of base plate, forms noise elimination gas-entered passageway.
Compared with prior art, the utlity model has following advantage:
(1) and the contrast of equal air pump, operating noise declines 7 ~ 8 decibels, original 55 decibels of left and right, existing 47 decibels of left and right;
(2) dust from gas is difficult for entering air chamber, has improved quality and working life;
(3) gas-entered passageway of gas increases, and can arbitrarily regulate air-flow size.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of original air pump.
Fig. 2 is the sectional view at A-A place in Fig. 1.
Fig. 3 is the utility model embodiment's structural representation.
Fig. 4 be in Fig. 3 B to structural representation.
In figure: 1-casing, 2-air chamber, 3-iron core, 4-swing frame, 5-rubber cup, 6-valve sheet, 7-pad, 8-base plate, 9-gas muffler lid, 10-suction port.
Embodiment
As shown in Fig. 3 ~ 4, a kind of air pump that improves noise elimination air intake structure, comprise casing 1, air chamber 2, pad 7 and base plate 8, described base plate 8 is arranged on casing 1 bottom, described pad 7 is arranged between base plate 8 and casing 1, the suction port 10 of described air pump is opened on base plate 8, described base plate 8 inner sides are provided with the gas muffler lid 9 for gas sucks and noise sound source is discharged through bolt, in described gas muffler lid 9, be provided with the noise elimination gas-entered passageway that one end is connected with suction port 10, the described noise elimination gas-entered passageway the other end leads to pad 7 bottoms.
In the present embodiment, this air pump is small-sized 2 air chambers 2 air pumps, its internal structure please refer to shown in Fig. 2, its main feature is: improved suction port 10 positions and installed a gas muffler lid 9 additional, overcome the shortcomings such as original air pump noise is large, the easy accumulation dust of suction port 10, make existing air pump more perfect.
In the present embodiment, described suction port 10 is the aperture of diameter 6.8mm, but is not limited to this, as long as the suction port of former air pump 10 is moved on to casing 1 bottom cover plate from casing 1 tip position.During work: the gas sucking from suction port 10 first, after noise elimination gas-entered passageway, enters pad 7 bottoms in air pump, enters air chamber 2 after pad 7 filters out dust again.
In the present embodiment, described noise elimination gas-entered passageway twist, because passage lengthens, adds curved, the noise sound source of having sent while therefore having stopped the gentle pump internal pendulum of the air-breathing sound source moving frame that directly suction gas causes fast, rubber cup, valve sheet work, gas filters through pad 7 again after noise elimination gas-entered passageway, makes dust from gas cannot enter air chamber 2.
In the present embodiment, described gas muffler lid 9 is to offer spiral fluted dome, described spiral chute can be to be in series with involute shape or nearly involute shape by the annular groove of several different-diameters, between described spiral chute and the inner side surface of base plate 8, forms noise elimination gas-entered passageway.Certainly, described noise elimination gas-entered passageway also can directly be arranged in gas muffler lid 9.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
