Embodiment
In order to better understand technology contents of the present invention, accompanying drawing is coordinated to be introduced technological scheme especially exemplified by specific embodiment.
Consult Fig. 1, the integrally-built explosive view of compressor, in the present embodiment, compressor comprises compressor case (1), compressor pump (2) and motor (3).Continue to consult Fig. 2, the explosive view of compressor pump structure in new type compressor, wherein said compressor pump (2) comprises exhaust noise silencing plate (20), lower cylinder lid (21), cylinder (22), upper cylinder lid (23) and rotating shaft (24).Cover at described lower cylinder and be provided with bearing (2114), rotating shaft (24) is connected with described lower cylinder lid (21) by described bearing (2114).Air-flow is from arriving the passage lower cylinder lid (21) through compression in the cylinder, passage in lower cylinder lid (21) enters cylinder (22), and then the passage entered between cylinder (22) and upper cylinder lid (23) is finally discharged.
In the present invention, the structure of inventor to lower cylinder lid (21) has carried out new design.Consult the front view of Fig. 3 lower cylinder lid (21), the face shown in Fig. 3 is the face corresponding with exhaust noise silencing plate (20).Exhaust noise silencing plate (20) together with lower cylinder lid (21) by being fixed on cylinder through the fixed component of fixed hole (2112).This face of the lower cylinder lid (21) shown at Fig. 3 offers groove, therefore just occurs a space between exhaust noise silencing plate (20) and lower cylinder lid (21).Relative to exhaust noise silencing plate 20 and lower cylinder lid (21) be fixed together formed space, hole (218) is inlet hole, and air-flow enters passage between cylinder (22) and upper cylinder lid (23) to discharge through air outlet hole (216).
Air-flow is entered by inlet hole (218), then arrives air outlet hole (216).By inlet hole (218) to air outlet hole (216), lower cylinder lid (21) is provided with the passage of groove as air-flow.In the present embodiment, first groove (210) is for holding inlet hole, namely first air-flow arrives the first groove (210), exhaust valve component (2115) is also placed with in the first groove (210), exhaust valve component (2115) is fixed in the first groove (210) by the exhaust valve component fixed hole (2110) in the first groove (210), therefore the first groove (210) is commonly referred to exhaust valve pool, in one end away from inlet hole (218) of the first groove (210) or the one end being expressed as close exhaust valve component fixed hole (2110), extend (initial offer) second groove (212), second groove (212) extends to air outlet hole (216) from the first groove (210) always, make air-flow can arrive air outlet hole (216) by the second groove (212) by inlet hole (218).Also arrange one at the second groove (212) to conflux chamber (2120), this chamber of confluxing (2120) is a part bloated in the second groove (212), width is larger than the average span of the second groove (212), edge camber, second groove (212) entirety is in line extension, is wherein provided with this chamber of confluxing (2120).Further, in the present embodiment, at the other end of the first groove (210), near one end of inlet hole, also offer the 3rd groove (214), 3rd groove (214) extends to the chamber of confluxing (2120) of the second groove (212) from the first groove (210), makes air-flow have second passage to arrive air outlet hole (216) from inlet hole (218).In enforcement, the 3rd groove (214) can initial one end with the first groove (210), also can be initial with other positions, is set to more excellent scheme in inlet hole one end.
The present invention by cylinder head being offered three grooves under compressor, because air inlet groove two ends are all provided with groove, the convolution of air-flow reduces, reduce the resistance that air-flow passes through, because two grooves can form two strands of air-flows by air-flow and two strands of air-flows converge in chamber of confluxing respectively, in the process converged, the air-flow of both direction clashes into mutually, produces peak value offset, pneumatic noise is reduced, and vibrations weaken.
Further, due to offering of two grooves, also increase the air displacement of compressor, improve refrigeration, improve the performance of compressor entirety.
Further, tested by inventor, preferably mode is the two ends the second groove (212) and the 3rd groove (214) being arranged at respectively the first groove (210), the length of increase air-flow path that like this can be larger, make the convolution of air-flow and resistance less, more be conducive to the reduction of noise, weakening of vibrations.
Further, the first groove (210) and the second groove (212) can linearly be offered, the relation of or approximate right angle at a right angle in one end of the first groove (210) between two grooves.Preferably, the 3rd groove (214), initial from the other end of the first groove (210), curvedly extends to air outlet hole along bearing relative to the opposite side of the second groove (212).Material is thus formed a groove ring around bearing in other words around one of bearing annular airslide, inlet hole and air outlet hole are all in this groove ring UNICOM.
Further, in the process implemented, the degree of depth of the first groove (210) is darker than the degree of depth of the second groove (212) and the 3rd groove (214), makes the first groove (210) and the second groove (212) and has height difference between the first groove (210) and the 3rd groove (214).Through the experiment implemented, the degree of depth of the first groove (210) preferably mode is 2-3 millimeter for making the bottom of the first groove (210) to the thickness of described lower cylinder head, second and the 3rd the degree of depth of groove (214) be 3-5 millimeter.If certainly the second groove (212) is different from the degree of depth of the 3rd groove (214), remain a kind of can reduce noise and shaking mode of execution specifically.Inventor studies discovery, and the width of the first groove (210) is preferably 5-10 millimeter, and the width of the second groove (212) is preferably 1-3 millimeter.
Further, inventor finds, above-mentioned lower cylinder can separately as a kind of inflator, the equipment of inflation is needed for similar compressor or other, need, under the environment of sealing, air-flow is poured a container or equipment, can use this inflator, this inflator also can keep the speed of air-flow especially.In enforcement, may different mode of execution, with above-described embodiment unlike, the parts of fixed rotating shaft or similar parts can not be set in inflator.A kind of inflator, comprising inflator comprises into the first groove (210), inlet hole (218) is had in one end of described first groove (210), the second groove (212) is extended in one end of described first groove (210), this second groove (212) extends to air outlet hole (216) always, in described second groove (212), be provided with one to conflux chamber (2120), the 3rd groove (214) is also extended described first groove (210), 3rd groove (214) extends to chamber (2120) of confluxing described in described second groove (212), the passage that air-flow consists of through described first groove (210) and the second groove (212) described inlet hole (218) is entered by described air outlet hole (216) and treats charger, and air-flow arrives described air outlet hole (216) through described first groove (210) via the chamber 2120 of confluxing that the passage that the 3rd groove (214) forms arrives the second groove (212) by described inlet hole (218) again and enters and treat charger.Other arrange the embodiment consulting lower cylinder.
Equally because the groove design of the present embodiment can reduce noise in gas replenishment process and vibrations.
