Specific embodiment
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, but not as to limit of the invention
It is fixed.
In conjunction with referring to shown in Fig. 1 to Fig. 6, according to an embodiment of the invention, cylinder assembly includes cylinder 1 and rotationally sets
The eccentric part 2 in cylinder 1 is set, is radially slided in cylinder 1 and is provided with slide plate 3, the extension end of slide plate 3 is connected to eccentric part 2
Periphery, and the cavity in eccentric part 2 and cylinder 1 is divided into suction chamber and discharge chamber, tonifying Qi hole 4 is provided on cylinder 1, it is sliding
The gas supplementary structure 5 for being connected to discharge chamber with tonifying Qi hole 4 is provided on piece 3.
Since tonifying Qi hole 4 is set up directly on cylinder 1, and tonifying Qi hole 4 is the gas supplementary structure 5 by being arranged on slide plate 3
It is connected to discharge chamber, and gas supplementing opening 4 is opened and closed by the reciprocating motion of slide plate 3, gas supplementing opening 4 is connected to gas supplementary structure 5
Area can be made greatly, therefore the air compensation of cylinder assembly can be made very big, while the tonifying Qi hole and gas supplementary structure processing letter
Just, cost is relatively low for folk prescription.
Preferably, tonifying Qi hole 4 is arranged close to the inner wall of cylinder 1, can make gas supplementary structure 5 more easily by tonifying Qi hole 4
It is connected to discharge chamber, reduces the length that tonifying Qi hole 4 is connected to by gas supplementary structure 5 with discharge chamber, guaranteed the structural strength of slide plate 3, make
Obtaining outside air can more easily be added into discharge chamber.
Preferably, tonifying Qi hole 4 partially overlaps with slide plate 3, so that gas supplementary structure 5 and the connection area in tonifying Qi hole 4 are bigger, energy
Gas supplementary structure 5 is enough further increased to the air compensation of discharge chamber, improves the tonifying Qi effect of cylinder assembly.
Preferably, tonifying Qi hole 4 is circular hole, elliptical aperture or rectangular opening.
Gas supplementary structure 5 is all round closure, the tonifying Qi slot of a side opening, and the opening of tonifying Qi slot is towards tonifying Qi hole 4.Tonifying Qi slot exists
It when reaching 4 position of tonifying Qi hole, can be more easily connected to comprehensively with tonifying Qi hole 4, and then pass through tonifying Qi slot for tonifying Qi hole 4
It is connected to discharge chamber, enables tonifying Qi smoothly and is entered in discharge chamber through tonifying Qi hole 4 in large quantities.
The section of tonifying Qi slot is trapezoidal, rectangle or arc.
In order to guarantee air compensation, the opening of tonifying Qi hole 4 towards tonifying Qi slot should to the greatest extent may be used with the connection area between tonifying Qi slot
Can it is big.
Gas supplementary structure 5 is selectively connected to tonifying Qi hole 4 and discharge chamber with the reciprocating motion of slide plate 3, in slide plate 3 to eccentric part
When 2 stretching, with the increase of extension elongation, gas supplementary structure 5 is connected to tonifying Qi hole 4, and then is connected to discharge chamber, by tonifying Qi hole 4
The air of entrance is added into discharge chamber, improves the air compression effectiveness in discharge chamber, when slide plate 3 reaches maximum position,
When bouncing back under the compression of eccentric part 2, gas supplementary structure 5 is gradually disconnected with discharge chamber, until be fully disconnected with discharge chamber,
Discharge chamber boil down to discharge chamber in the cyclic process of cylinder at this time, between discharge chamber due to gas supplementary structure 5 and at this time no longer
Connection, therefore the gas compressed can not be discharged through gas supplementary structure 5 and tonifying Qi hole 4, be merely able to be discharged via gas vent, gas supplementary structure
5 and tonifying Qi hole 4 will not influence the compression effectiveness of air.
Slide plate 3 stretch out during, gas supplementary structure 5 be connected to tonifying Qi hole 4 and discharge chamber original position, slide plate 3 and partially
Angle between the initial rotation position of center portion 2 is a, and wherein the initial rotation position of eccentric part 2 is the position that slide plate 3 is fully retracted
Set namely Fig. 1 shown in position.
During slide plate 3 retracts, gas supplementary structure 5 closes the original position of the communicating passage of tonifying Qi hole 4 and discharge chamber,
Angle between slide plate 3 and the initial rotation position of eccentric part 2 is b.
The wherein size of a and b and identical, can also be different, and specifically can need be adjusted according to structure.
It is illustrated below with reference to the course of work of the Fig. 3 to Fig. 6 to cylinder assembly.
Cylinder assembly is first in position shown in Fig. 3, and eccentric part 2 rotates clockwise at this time, where eccentric part 2 and slide plate 3
The gap between cylinder wall at position is gradually increased, and slide plate 3 gradually stretches out, as 2 rotational angle a of eccentric part, slide plate 3 at this time
Certain length is stretched out, tonifying Qi hole 4 is connected to by the gas supplementary structure 5 on slide plate 3 with discharge chamber simultaneously, begins through 4 pairs of tonifying Qi hole row
Air cavity carries out tonifying Qi, as shown in Figure 4.When eccentric part 2 turns to middle position, pass through benefit between tonifying Qi hole 4 and discharge chamber at this time
The area that depressed structure 5 is connected to is maximum, and superfeed pressure is greater than the gas pressure in discharge chamber, and gas is from tonifying Qi hole 4 through tonifying Qi
Structure 5 continues to fill into discharge chamber, as shown in Figure 6.Eccentric part 2 continues to rotate later, when eccentric part 2 turns to and initial position
Between angle when being b, slide plate 3 retracts to certain length, and gas supplementary structure 5 begins breaking the connection between discharge chamber at this time,
Air in discharge chamber continues to be discharged after compression from exhaust outlet.
According to an embodiment of the invention, compressor includes cylinder assembly, which is above-mentioned cylinder assembly.
It certainly, is the preferred embodiment of the present invention above.It should be pointed out that for those skilled in the art
For, without departing from the basic principles of the invention, several improvements and modifications can also be made, these improvements and modifications
It is considered as protection scope of the present invention.
