Embodiment
In order better to understand technology contents of the present utility model, especially exemplified by specific embodiment and cooperate accompanying drawing that technological scheme is introduced.
Consult Fig. 1, the integrally-built explosive view of compressor, compressor comprises compressor case (1), compressor pump (2) and motor (3) in the present embodiment.Continue to consult Fig. 2, the explosive view of compressor pump structure in the new type compressor, wherein said compressor pump (2) comprise exhaust noise silencing plate (20), therapeutic method to keep the adverse qi flowing downward cylinder cap (21), cylinder (22), upper cylinder lid (23) and rotating shaft (24).Cover at described lower cylinder and to be provided with bearing (2114), rotating shaft (24) is connected with described therapeutic method to keep the adverse qi flowing downward cylinder cap (21) by described bearing (2114).The passage of air-flow from process compression arrival lower cylinder lid (21) cylinder, enter cylinder (22) through the passage in the therapeutic method to keep the adverse qi flowing downward cylinder cap (21), and then the passage that enters between cylinder (22) and the upper cylinder lid (23) is discharged at last.
In the utility model, the inventor has carried out new design to the structure of therapeutic method to keep the adverse qi flowing downward cylinder cap (21).Consult the front view of Fig. 3 therapeutic method to keep the adverse qi flowing downward cylinder cap (21), the face that shows among Fig. 3 is the face corresponding with exhaust noise silencing plate (20).Exhaust noise silencing plate (20) is fixed on the cylinder by the fixed component that passes fixed hole (2112) with therapeutic method to keep the adverse qi flowing downward cylinder cap (21).This face of the therapeutic method to keep the adverse qi flowing downward cylinder cap (21) that shows at Fig. 3 offers groove, so a space just occurred between exhaust noise silencing plate (20) and the therapeutic method to keep the adverse qi flowing downward cylinder cap (21).With respect to the space that exhaust noise silencing plate 20 and therapeutic method to keep the adverse qi flowing downward cylinder cap (21) are fixed together and form, hole (218) be inlet hole, and air-flow enters cylinder (22) and upper cylinder through air outlet hole (216) and covers passage between (23) with discharge.
Air-flow enters by inlet hole (218), then arrives air outlet hole (216).By inlet hole (218) to the air outlet hole (216), be provided with groove as the passage of air-flow at therapeutic method to keep the adverse qi flowing downward cylinder cap (21).In the present embodiment, the first groove (210) is used for holding inlet hole, be that air-flow at first arrives the first groove (210), in the first groove (210), also be placed with exhaust valve component (2115), 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 the exhaust valve pool, the first groove (210) away from an end of inlet hole (218) or be expressed as a end near exhaust valve component fixed hole (2110), extend (initial offering) the second groove (212), the second groove (212) extends to air outlet hole (216) from the first groove (210) always, so that air-flow can arrive air outlet hole (216) by inlet hole (218) by the second groove (212).At the second groove (212) chamber (2120) of confluxing is set also, this chamber of confluxing (2120) is part that bloats in the second groove (212), the average span of Width the second groove (212) is large, the edge camber, the extension that is in line of the second groove (212) integral body wherein is provided with this chamber of confluxing (2120).Further, in the present embodiment, the other end in the first groove (210), end near inlet hole, also offer the 3rd groove (214), the 3rd groove (214) extends to the chamber of confluxing (2120) of the second groove (212) from the first groove (210), so that air-flow has second passage to arrive air outlet hole (216) from inlet hole (218).In the enforcement, the 3rd groove (214) can be initial and an end of the first groove (210), also can be initial and other positions, be set to more excellent scheme at inlet hole one end.
The utility model is offered three grooves by cylinder head under compressor, because air inlet groove two ends all are provided with groove, the convolution of air-flow reduces, reduced the resistance that air-flow passes through, because two grooves can form two strands of air-flows and two strands of air-flows converge in the chamber of confluxing by air-flow respectively, the air-flow of both direction clashes into mutually in the process of converging, and produces peak value offset, so that pneumatic noise reduces, vibrations weaken.
Further, because offering of two grooves also strengthened the air displacement of compressor, improve refrigeration, improved the performance of compressor integral body.
Further, test by the inventor, better mode is for being arranged at the second groove (212) and the 3rd groove (214) respectively the two ends of the first groove (210), the length of increase air-flow path that like this can be larger, so that the convolution of air-flow and resistance are less, more be conducive to the reduction of noise, the weakening of vibrations.
Further, the first groove (210) and the second groove (212) can linearly be offered, and meet at right angles or the relation of approximate right angle at an end of the first groove (210) between two grooves.Better, the 3rd groove (214) is initial from the other end of the first groove (210), curvedly extends to air outlet hole along bearing with respect to the opposite side of the second groove (212).So just formed the airslide that centers in other words an annular of bearing around a groove ring of bearing, inlet hole and air outlet hole are all in this groove ring UNICOM.
Further, in the process of implementing, 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), so that between the first groove (210) and the second groove (212) and the first groove (210) and the 3rd groove (214) height difference is arranged.Through the experiment of implementing, the better mode of the degree of depth of the first groove (210) is for so that the bottom of the first groove (210) is the 2-3 millimeter to the thickness of described lower cylinder head, and the degree of depth of the second and the 3rd groove (214) is the 3-5 millimeter.If the second groove (212) is different from the degree of depth of the 3rd groove (214) certainly, remain a kind of concrete can reducing noise and shake mode of execution.The inventor studies discovery, and the width of the first groove (210) is preferably the 5-10 millimeter, and the width of the second groove (212) is preferably the 1-3 millimeter.
Further, the inventor finds, above-mentioned lower cylinder can be separately as a kind of inflator, be used for similar compressor or other equipment that need to inflate, need under the environment of sealing, air-flow be poured a container or equipment, can use this inflator, this inflator also can keep the speed of air-flow especially.In the enforcement, mode of execution that may be different, different from above-described embodiment is that parts or the similar parts of fixed rotating shaft can be set in inflator.A kind of inflator, comprise that inflator comprises into the first groove (210), end at described the first groove (210) has inlet hole (218), end at described the first groove (210) extends the second groove (212), this second groove (212) extends to air outlet hole (216) always, in described the second groove (212), be provided with the chamber (2120) of confluxing, also extend the 3rd groove (214) at described the first groove (210), the 3rd groove (214) extends to the described chamber of confluxing (2120) in described the second groove (212), the passage that air-flow forms through described the first groove (210) and the second groove (212) by described inlet hole (218) is entered by described air outlet hole (216) treats charger, and the air-flow chamber 2120 of confluxing that arrives the second groove (212) through described the first groove (210) via the passage of the 3rd groove (214) composition by described inlet hole (218) arrives described air outlet hole (216) again and enters and treat charger.The embodiment of lower cylinder is consulted in other settings.
It is same because the groove design of present embodiment can reduce noise and the vibrations in the gas replenishment process.
