[ , The complete assembly of the compression diaphragm pump is completed (as shown in Figures 1 and 10).

Figs. 11 and 12 are views showing the operation of the conventional compression diaphragm pump of Figs. 1 to 10. Fig.

First, when power is supplied to the motor 10, the vibration plate 40 is operated by the motor output shaft 11 to rotate, and the three eccentric circular plates 52 on the eccentric circular mount 50 continuously move up and down Continuously move with an up-and-down reciprocal stroke.

Secondly, during this time, the three piston action zones 74 and the three pumping pistons 80 in the diaphragm membrane 70 are continuously operated by the reciprocating stroke of the three tubular eccentric circular plates 52, It moves by displacement.

 Third, when the tubular eccentric circular plate 52 is moved in a down stroke, the pumping piston 80 and the piston action zone 74 are displaced downward, causing the piston disk 98 of the piston valve assembly 90 The tap water W is pushed into the open state and passed through the water inlet orifice 21 of the pump head cover 20 and the inlet port 97 of the piston valve assembly 90 to the preliminary- (As indicated by the arrow extending from W in the enlarged view of Fig. 11).

Fourth, when the tubular eccentric circular plate 52 is moved in an up stroke, the pumping piston 80 and the piston action zone 74 are displaced upward so that the piston disk 98 of the piston valve assembly 90 Is pulled into the closed state to compress the tap water W in the pre-compression chamber 26 to increase the water pressure to a range of 80 psi-100 psi. As a result, the pressurized water Wp pushes the plastic check valve 94 of the piston valve assembly 90 to be opened.

Fifthly, when the plastic check valve 94 of the piston valve assembly 90 is pushed to the open state, the pressurized water Wp in the pre-compression chamber 26 is discharged to the corresponding sector of the central discharge mount 92 Chamber 27 through the group of ports 95 and then out of the water discharge orifice 22 of the pump head cover 20. As shown in FIG.

Finally, successive repetitive actions of each group of discharge ports 95 for the three sectors of the central discharge mount 92 cause the pressurized water Wp to be continuously released out of the conventional compression diaphragm pump, (RO) -filtered by the cartridge (RO) -filter, so that the final filtered pressurized water Wp can be used in the reverse osmosis purification system.

Referring to Figures 13 and 14, serious vibration-related disadvantages have existed for a long time in conventional compression diaphragm pumps. As described above, when power is supplied to the motor 10, the shake plate 40 is driven by the motor output shaft 11 to rotate, and three tubular eccentric circular plates 52 on the eccentric circular mount 50 The three piston action zones 74 of the diaphragm membrane 70 are continuously moved in an up-and-down reciprocal stroke by a reciprocating stroke of the three tubular eccentric circular plates 52 And is continuously moved to move up and down to force the force F continuously acting on the bottom surface of each piston action zone 74. [

On the one hand, a corresponding plurality of rebounding forces Fs are generated in reaction to the acting force F exerted on the bottom surface of the diaphragm membrane 70, so that each of the diaphragm membranes 70 The squeezing phenomenon caused by the rebounding force Fs is generated on the section of the diaphragm membrane 70 since it is distributed over the entire floor area of the corresponding piston operating zone 74 of the diaphragm membrane 70 .

The squeezing phenomenon is a phenomenon in which the diaphragm membrane 70 contacts the rounded shoulder 57 of the horizontal upper surface 53 of the tubular eccentric circular plate 52 among all the distributed components of the rebounding force Fs as shown in Fig. 14, the compression phenomenon at the bottom position P is the maximum, because the maximum component force applied to the bottom position P is generated.

Each of the bottom positions P of the piston action zone 74 of the diaphragm membrane 70 has a frequency of four oscillations per second since the rotational speed of the motor output shaft 11 of the motor 10 reaches the range of 700 to 1200 rpm It undergoes compression. In this situation, the bottom position P of the diaphragm membrane 70 is always the first broken place in the conventional compression diaphragm pump, thus not only shortening the service life, but also reducing the conventional function of the conventional diaphragm pump Is also a fundamental cause of termination.

The disadvantages associated with the compression phenomenon resulting from the continuous application of the force F to the bottom surface of each piston acting zone 74 of the diaphragm membrane 70 as a result of the movement of the tubular eccentric circular plate 52 How to reduce it substantially is an urgent and important issue.

It is an object of the present invention to provide a compression diaphragm pump having an eccentric circular plate structure which is a cylindrical or inverted truncated conical eccentric circular plate disposed in an eccentric circular mount.

It is an object of the present invention to provide a compression diaphragm pump having an eccentric circular plate structure which is a cylindrical or inverted frustoconical eccentric round or cylindrical arrangement disposed in an eccentric circular mount wherein the cylindrical or conical frusto- The circular plate includes an annular positioning groove, a vertical or frusto-conical flange, and an annular upper surface portion that is inclined relative to the horizontal to form an inclined upper ring between the annular positioning groove and the vertical flanks.

Owing to the inclined top ring, oblique pulling and squeezing phenomena, which occur more frequently in conventional tubular eccentric circular plates, are caused by the inclined upper ring being located in the bottom area of the corresponding piston action zone of the diaphragm membrane It is completely removed because it is flatly attached.

Thus not only the durability of the diaphragm membrane is improved, but also the life span of the diaphragm membrane is significantly extended to better withstand the continuous frequent pumping action of the eccentric circular plate.

It is a further object of the present invention to provide an eccentric circular plate for a compression diaphragm pump wherein the eccentric circular plate structure is a cylindrical or conical frusto-conical eccentric circular plate disposed on an eccentric circular mount and the eccentric circular plate has an annular positioning groove, Or frusto-conical flank, and a sloped top ring formed between the annular positioning groove and the vertical or frusto-conical flanks.

In addition, due to the inclined top ring, all distributed components of the rebounding force on the cylindrical eccentric circular plate, which are generated in reaction to the acting force caused by the pumping action, Is substantially reduced because it closely attaches to the bottom region of the corresponding piston action zone.

In achieving the objects described above, it is not intended to limit the scope of the invention, but at least the following advantages are achieved:

1. The durability of the diaphragm membrane to withstand the highly pumping action of the cylindrical or conical frusto-conical eccentric circular plate is substantially improved.

2. The power consumption of the compression diaphragm pump is greatly reduced because of the small current consumed as a result of the high frequency compression described above.

FIGS. 15 to 18 are illustrations of an eccentric circular plate structure for a compression diaphragm pump according to a first exemplary embodiment of the present invention. FIG.

The eccentric circular plate structure is a cylindrical eccentric circular plate 52 mounted on the eccentric circular mount 50. The cylindrical eccentric circular plate includes an annular upper surface portion that is inclined relative to the horizontal to form an inclined upper ring 58 between the annular positioning groove 55 and the vertical flank 56, rings replace the conventional rounded shoulders 57 on each tubular eccentric circular plate 52 of the eccentric circular mount 50. [

19-21 illustrate the operation of the eccentric circular plate structure for the compression diaphragm pump of the first exemplary embodiment of the present invention.

First, when power is supplied to the motor 10, the vibration plate 40 is operated by the motor output shaft 11 to rotate, and the three eccentric circular plates 52 on the eccentric circular mount 50 continuously move up and down Continuously move with reciprocal stroke.

Second, the three piston action zones 74 in the diaphragm membrane 70 are continuously operated by the up and down reciprocating strokes of the three cylindrical eccentric circular plates 52 to move up and down.

Third, when the tubular eccentric circular plate or the cylindrical eccentric circular plate 52 moves upwardly in the piston action zone 74 and upward stroke, the acting force F is applied to the corresponding annular positioning projection 76 of the diaphragm membrane 70 and the outer Will pull the partial portion between the rising rims 71 at an angle (diagonally).

Compared with the operation of the conventional tubular eccentric circular plate 52 shown in Fig. 14 and the cylindrical eccentric circular plate 52 of the present invention shown in Fig. 20, at least the following two differences are apparent.

In the case of the conventional tubular eccentric circular plate 52 shown in Fig. 14, the maximum rebounding force Fs among all the distributed components is a component applied to the contact bottom position P of the diaphragm membrane 70, This is located at the edge of the rounded shoulder 57 on the horizontal top surface 53 of the tubular eccentric circular plate 52 and also the "squeezing" at the point P is the maximum. With this nonlinear distribution of "squeezing phenomena", the effect of being tilted (diagonally) is increased. In contrast, in the case of the cylindrical eccentric circular plate 52 shown in FIG. 20, the distribution components of the rebounding force Fs are such that the sloped upper ring 58 contacts the piston acting zone 74 of the diaphragm membrane 70 It becomes more linear because it closely attaches to the bottom area, and most of the oblique pulling action is eliminated due to the reduction of compression.

20, since the rebounding force Fs is inversely proportional to the contact area under the same acting force F, the magnitude of the distributed component Fs of the rebounding force Fs with respect to the cylindrical eccentric circular plate 52 of the present invention Is substantially smaller than the size of the distributed component of the rebounding force Fs for the conventional tubular eccentric circular plate 52 shown in Fig.

The improved distribution linearity and reduced size of the rebounding force (Fs) components form an inclined upper ring 58 between the annular positioning groove 55 and the vertical flank 56 in the eccentric circular mount 50 Which in turn provides at least the following advantages. Firstly, the improved force component distribution can be achieved by providing, in addition to the horizontal upper surface 53 of the tubular eccentric circular plate 52, a diaphragm membrane 53, which is caused by a high frequency compression phenomenon occurring in a conventional configuration as a result of the rounded shoulder 57, Thereby eliminating the sensitivity to breakage of the battery 70. Second, since the magnitude of the rebounding force components decreases, the three piston operating zones 74 of the diaphragm membrane 70, which are operated by the up-and-down reciprocating strokes of the three tubular eccentric circular plates 52 or the cylindrical eccentric circular plates 52, The total rebounding force Fs of the diaphragm membrane 70 caused by the acting force F during the vertical displacement is reduced in a square manner.

These advantages lead to the following practical advantages:

1. The durability of the diaphragm membrane 70 to withstand the frequent pumping action of the cylindrical eccentric circular plate 52 is substantially improved.

2. Since the current consumed as a result of frequent squeezing phenomena is small, the power consumption of the compression diaphragm pump is greatly reduced.

3. As the power consumption is reduced, the operating temperature of the compression diaphragm pump is very low.

4. Most of the undesirable bearing noise caused by the aging of the lubricating oil in the compression diaphragm pump, which is generally promoted by high operating temperatures, is largely eliminated.

Test results performed in the prototype of the present invention are as follows.

A. The diaphragm membrane (70) tested has more than doubled its service life.

B. The current consumption reduction exceeds 1 ampere.

C. The operating temperature has been reduced by more than 15 degrees Celsius.

D. The softness of bearings is improved.

22-24, there is shown an exemplary view of an eccentric circular plate structure for a compression diaphragm pump of a second exemplary embodiment of the present invention, wherein the eccentric circular plate structure is a conical frusto-conical eccentric circular plate 502, Is provided on the circular mount (500).

The frusto-conical eccentric circular plate 502 integrally includes a conical frusto-conical flank 506 and an inclined upper ring 508 whose outer diameter is widened, Is still smaller than the inner diameter of the working hole 61 and an inclined upper ring 508 extends between the annular positioning groove 505 and the conical frusto-conical flange 506.

Figs. 25-27 are illustrative drawings showing a modified operation of the eccentric circular plate structure for the compression diaphragm pump of the second exemplary embodiment of the present invention. Fig.

First, when power is supplied to the motor 10, the shake plate 40 is operated by the motor output shaft 11 to rotate, and three truncated conical eccentric circular plates 502 on the eccentric circular mount 500 are continuously Continuously move up and down reciprocal stroke.

Second, the three piston action zones 74 of the diaphragm membrane 70 are continuously operated by the up-and-down reciprocating stroke of the three frusto-conical eccentric circular plates 502 to move up and down.

Third, when one frustoconical eccentric circular plate 502 of the present invention is moved in the upward stroke and the corresponding piston action zone 74 is displaced upward, the acting force F is applied to the corresponding annular positioning projection 48 of the diaphragm membrane 70 (Obliquely) the portion of the space between the outer ram 76 and the outer ramp 71.

As a result, the inclusion of the sloped top ring 508 in the eccentric circular mount 500 eliminates breakage of the diaphragm membrane 70 caused by the highly squeezing phenomenon, The rebound force Fs of the frrom membrane 70 is greatly reduced. On the other hand, even when the outer diameter of the frusto-conical eccentric circular plate 502 is extended by the conducted frusto-conical flank 506, the frustoconical eccentric circular plate 502 and the operation hole 61 of the pump head body 60 The possibility of the collision (collision)

Further, under the same acting force F, the rebounding force Fs is inversely proportional to the contact area. The expanded outer diameter of the conical frusto-conical eccentric circular plate 502 increases the contact area between the bottom surface of the diaphragm membrane 70 and the sloped upper ring 508 (as indicated by the ring A shown in Fig. 27 Likewise, in the conical frusto-conical eccentric circular plate 502 of the present invention, All distributed components of the rebound force Fs for further reduction.

Thus, the conical frusto-conical eccentric circular plate 502 of this embodiment of the present invention provides at least part of the following advantages:

1. The durability of the diaphragm membrane 70 to withstand the high frequency pumping action of the conical frusto-conical eccentric circular plate 502 is substantially increased.

2. Since the current consumed as a result of frequent squeezing phenomena is small, the power consumption of the compression diaphragm pump is greatly reduced.

3. Since the power consumption is reduced, the operating temperature of the compression diaphragm pump is extremely low.

4. Most of the undesirable bearing noise from the aged lubricant of the compression diaphragm pump, which is aggravated by accelerated aging due to the high operating temperature, is largely eliminated.

5. The service life of the compression diaphragm pump is further extended since all distributed components of the rebounding force Fs for the conducted frusto-conical eccentric circular plate 502 of the present invention are reduced.

The combinational eccentric roundel 502 includes a circular mount 511 and a separately detachable inverted frustoconical round yoke 521 and the outer diameter of the frusto conical circular yoke 521 is But is still smaller than the inner diameter of the operating hole 61 of the pump head body 60. In this embodiment, the round mount 511 has a bottom-layer base with a positioning crescent surface 512 facing the inside, and an arm-thread bore 514 and a protruding cylinder 513 having a female-threaded bore. Conducted truncated conical circular yoke 521 is sleeved over a corresponding circular mount 511 and has a truncated conical flank 522 as well as an integral hollow structure stacked in three layers, 523, an upper bore, a middle bore 524 and a lower bore 525. The sloped upper ring 526 extends from the upper bore 523 to the truncated conical flange 522 And the bore diameter of the upper bore 523 is larger than the outer diameter of the projecting cylinder 513. [ The bore diameter of the intermediate bore 524 is approximately equal to the outer diameter of the protruding cylinder 513 and the bore diameter of the lower bore 525 is approximately equal to the outer diameter of the bottom- And the crescent is engaged with the corresponding surface of the lower bore to prevent relative rotation of the circular yoke 521 and the corresponding circular mount 511. A positioning annular groove 515 is formed between the protruding cylinder 513 and the inner wall of the upper bore 523 when the frusto-conical circular yoke 521 is sleeved on the circular mount 511. (Figs. 30 and 31 As shown.

As a result, the inclusion of the sloped top ring 526 in the conical frusto-conical circular yoke 521 of the eccentric circular mount 500 is caused by a highly squeezing phenomenon (as shown in Figures 33 and 34) Thereby eliminating the susceptibility of the diaphragm membrane 70 to breakage and also greatly reducing the rebounding force Fs of the diaphragm membrane 70 caused by the acting force F ).

Further, under the same acting force F, the rebounding force Fs is inversely proportional to the contact area.
