The foregoing issues of overall “resonant shakes” and the “water leakage” for the conventional five-compressing-chamber diaphragm pump incurred by the foregoing primary vibrating drawback are also happened in the piston valvular assembly 900. Therefore, how to substantially reduce all the drawbacks associated with the operating vibration for the five-compressing-chamber diaphragm pump becomes an urgent and critical issue indeed.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which has innovative mating means for a pump head body and a diaphragm membrane, where the pump head body includes five operating holes and a basic curved dent circum-disposed around the upper side of each operating hole while the diaphragm membrane includes five equivalent piston acting zones each of which with a acting zone hole, an annular positioning protrusion for each acting zone hole formed, and a basic curved protrusion circum-disposed around each concentric annular positioning protrusion in corresponding position with each mating basic curved dent in the pump head body so that five basic curved protrusions completely insert into corresponding five basic curved dents with a short length of moment arm in generating less torque, which is obtained by length of moment arm multiplying a constant acting force and primarily causes adverse vibration. With less torque, the vibration strength of the five-compressing-chamber diaphragm pump is substantially reduced.
Another object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which has innovative mating means for a pump head body and a diaphragm membrane, where the pump head body has five basic curved dents and the diaphragm membrane has five basic curved protrusions such that five basic curved protrusions completely insert into corresponding five basic curved dents with a short length of moment arm in generating less torque, which is obtained by length of moment arm multiplying a constant acting force and primarily causes adverse vibration. With less torque, the vibration strength of the compressing diaphragm pump is substantially reduced. Having the present invention installed on the housing of the reverse osmosis purification unit on the water supplying apparatus in either the settled home or mobile home pillowed by a conventional cushion base with rubber shock absorber, the harassing noise of the “resonant shakes” incurred in the five-compressing-chamber diaphragm pump can be completely eliminated.
The further object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which includes a cylindrical eccentric roundel disposed in an eccentric roundel mount. The cylindrical eccentric roundel basically comprises an annular positioning dent, a vertical flank and a sloped top ring created from the annular positioning dent to the vertical flank. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred in a conventional tubular eccentric roundel are completely eliminated because the sloped top ring flatly attaches the bottom area of corresponding piston acting zone for a diaphragm membrane. Thus, not only the durability of the diaphragm membrane for sustaining the pumping action of high frequency from the cylindrical eccentric roundels is mainly enhanced. But also the service lifespan of the five-compressing-chamber diaphragm pump is exceedingly prolonged.
The other object of the present invention is to provide a five-compressing-chamber diaphragm pump with multiple effects, which includes a cylindrical eccentric roundel disposed in an eccentric roundel mount. The cylindrical eccentric roundel basically comprises an annular positioning dent, a vertical flank and a sloped top ring created from the annular positioning dent to the vertical flank. By means of the sloped top ring, all distributed components of the rebounding force for the cylindrical eccentric roundels reacting to the an acting force caused by the pumping action are substantially reduced because the sloped top ring flatly attaches the bottom area of corresponding piston acting zone for a diaphragm membrane.
Thus, some benefits are obtained as below.
1. The durability of the diaphragm membrane for sustaining the pumping action of high frequency from the cylindrical eccentric roundels is mainly enhanced.
2. The power consumption of the five-compressing-chamber diaphragm pump is tremendously diminished due to less current being wasted in the “squeezing phenomena” of high frequency.
3. The working temperature of the five-compressing-chamber diaphragm pump is tremendously subdued due to less power consumption being used.
4. The annoying noise of the bearing incurred by the aged lubricant in the five-compressing-chamber diaphragm pump, which is expeditiously accelerated by the high working temperature, is mostly eliminated.

A basic curved dent 65 is circum-disposed around the upper side of each operating hole 61 in the pump head body 60 (as shown in
Moreover, a cylindrical eccentric roundel 52 in an eccentric roundel mount 50 basically comprises a sloped top ring 58 created from the annular positioning dent 55 to the vertical flank 56 (as shown in
Please refer to
Comparing to the operation of conventional five-compressing-chamber diaphragm pump, a length of moment arm L1 from the outer raised brim 71 to the peripheral of the annular positioning protruding block 76 in the diaphragm membrane 70 is obtained (as shown in
By illustration of foregoing comparative result, it apparently shows that the length of moment arm L2 is shorter than the length of moment arm L1.
While the resultant torque is calculated by same acting force F multiplying the length of moment arm, the resultant torque of the present invention is smaller than that of the conventional five-compressing-chamber diaphragm pump since the length of moment arm L2 is shorter than the length of moment arm L1.
With the smaller resultant torque of the present invention, the vibration strength related is substantially reduced.
Through practical pilot test for the sample of the present invention, the result shows that the vibration strength related is only one tenth (10%) of vibration strength in the conventional five-compressing-chamber diaphragm pump.

Secondly, five piston acting zones 74 in the diaphragm membrane 70 are orderly driven by the up-and-down reciprocal stroke of five cylindrical eccentric roundels 52 to move in up-and-down displacement;
Thirdly, when the conventional tubular eccentric roundel or cylindrical eccentric roundel 52 of the present invention moves in “up stroke” with piston acting zone 74 in up displacement, an acting force F will obliquely pull the partial portion between corresponding annular positioning protrusion 76 and outer raised brim 71 of the diaphragm membrane 70;

In the case of conventional tubular eccentric roundel 52, among all distributed components of the rebounding force Fs, the component force happened at the contacting bottom position P of the diaphragm membrane 70 with the rounded shoulder 57 of the horizontal top face 53 in the tubular eccentric roundel 52 is maximum so that the “squeezing phenomenon” happened here is also maximum (as shown in
Moreover, under the same acting force F, the rebounding force Fs is inversely proportional to the contact area so that all distributed components of the rebounding force Fs for the cylindrical eccentric roundels 52 of the present invention (as shown in
From above comparison, two advantages are inherited by means of the sloped top ring 58 created from the annular positioning dent 55 to the vertical flank 56 in the eccentric roundel mount 50.
