Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 4, a kind of low noise Portable air compressor of the present utility model, comprise air compressor body 1, the front end of described air compressor body 1 is provided with front cover 2, described front cover 2 is connected with cylinder-piston assembly 3, described front cover 2 inside is provided with air inlet duct 21, one end of described air inlet duct 21 offers the air outlet 22 be communicated with cylinder-piston assembly 3, the other end of described air inlet duct 21 offers the suction port 23 with ft connection, some sound insulation sheets 24 are provided with between the suction port 23 of described air inlet duct 21 and air outlet 22, gas-entered passageway 25 is formed between described sound insulation sheet 24, described gas-entered passageway 25 is arranged in mazy type, described front cover 2 is connected with the cover plate 26 for being sealed into air drain 21 outer side surface.In air compressor operation process, extraneous gas enters cylinder-piston assembly 3 by suction port 23 through gas-entered passageway 25, the noise that air compressor body 1 inside produces enters mazy gas-entered passageway 25 by air outlet 22, the energy of noise is constantly attenuated in mazy gas-entered passageway 25, finally spread out of by suction port 23, reach the object of air compressor sound-deadening and noise-reducing, the scheme of directly discharging noise relatively at present obtains larger improvement, greatly promotes the experience of user.
Described suction port 23 can be arranged at front cover 2, and the suction port 23 of the present embodiment is preferably disposed on cover plate 26, and described suction port 23 is communicated with air inlet duct 21.Front cover 2 is generally die castings, and structure is more complicated, and the expense of mfg. moulding die is higher, by arranging suction port 23 at the front cover 2 assembled with it, can simplify the structure of front cover 2, saves cost of production.
As preferably, the inside of described front cover 2 is provided with internal partition 27, and described air inlet duct 21 can be formed by the inner side surface of internal partition 27 with front cover 2.This internal partition 27 can carry out the assembling in later stage as independent part, its objective is and can form difform air inlet duct 21, to be combined to form different mazy type noise-reducing structures from sound insulation sheet 24, realizes better erasure effect.
The air outlet 22 of the present embodiment is opened in internal partition 27.The air outlet 22 being arranged at internal partition 27 can simplify front cover 2 structure, and air outlet 22 is arranged close to cylinder-piston assembly 3, and the gas out directly enters cylinder-piston assembly 3; The noise that cylinder-piston assembly 3 produces enters gas-entered passageway 25 by air outlet 22 and carries out noise reduction.
As preferably, the air inlet duct 21 of the present embodiment is arranged in circular arc.Certainly, described air inlet duct 21 can be square, other different shape such as waveform.
Described some sound insulation sheets 24 are arranged in compartment, and described sound insulation sheet 24 offers breach 28, and breach 28 mutual dislocation on adjacent sound insulation sheet 24 is arranged.Noise enters from suction port 23, successively through the sound insulation sheet 24 that above-mentioned compartment is arranged, arranges, sound wave constantly to be detoured to another cell by a cell, thus increases soundproof effect because breach 28 mutual dislocation forms mazy type.
As preferably, the sound insulation sheet 24 of the present embodiment is provided with sound-absorbing sponge, and described sound-absorbing sponge increases the erasure effect in gas-entered passageway 25, makes noise reach maximized reduction.Seal rubber pad is provided with between described front cover 2 and cover plate 26.Sealing rubber cushion avoids noise to be spread out of by the joint between front cover 2 and cover plate 26, and affects noise reduction.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
