The combination of the chamber diaphragm booster pump (as shown in Figures 1 and 9).

As shown in FIG. 10 and FIG. 11, it is the operation of the above-mentioned conventional four-pressure diaphragm pump. When the output shaft 11 of the motor 10 rotates, the tilting eccentric cam 40 is rotated, and at the same time, the four balance wheels 52 on the balance wheel housing 50 are sequentially generated to reciprocate up and down, and the diaphragm plate 70 is four. The piston actuating zone 74 is also actuated by the up-and-down movement of the four balance wheels 52, and is synchronously pushed up and down to generate a reverse up and down displacement. Therefore, when the balance wheel 52 is actuated downward, the diaphragm is synchronously The piston actuation zone 74 of the blade 70 and the piston pusher block 80 are pulled down so that the piston plate 98 of the piston valve body 90 Pushing open, and tap water W from the water inlet 21 of the pump head cover 20 enters the plenum chamber 26 via the water inlet hole 97 (as indicated by an arrow W in FIG. 10 and its enlarged view); when the balance wheel 52 is turned toward When the push-up action is actuated, the piston actuation zone 74 and the piston pusher block 80 of the diaphragm 70 are simultaneously topped up, and the water in the pressurization chamber 26 is squeezed to increase the water pressure to 100 psi to 150 psi. Therefore, the boosted high-pressure water Wp can push the check rubber pad 94 on the drain seat 92 away, and continuously flow into the high-pressure water chamber 27 through the drain holes 95 of the drain seat 92, and then The water outlet 22 of the pump head cover 20 is discharged outside the four plenum diaphragm pump (as shown by the arrow Wp in FIG. 11 and its enlarged view), thereby providing the reverse osmosis filter for the RO membrane tube in the reverse osmosis water filter. Water pressure, or the water pressure required to output the bath and water supply equipment in the RV.

As shown in Figures 12 and 13, the above-mentioned conventional four-bore diaphragm diaphragm pump has existed for a long time. A serious deficiency, when it is actuated, the four balance wheels 52 will alternately push up the piston actuation zone 74 of the diaphragm 70, which is equal to the position of the four piston actuation zones 74 on the underside of the diaphragm 70, constantly applying With an upward force F (as shown in FIG. 13), the force F is multiplied by the moment generated by the arm length L1 between the outer rib 71 and the locating cam block 76 (ie, torque = F × L1) ), the whole pump body will be vibrated. Since the rotational speed of the shaft 10 of the motor 10 is as high as 800-1200 rpm, the strength of the shock generated by the four balance wheels 52 in rotation is always high.

Therefore, as shown in Figure 14, the conventional four-bore diaphragm pump will be installed at the outer edge of the pump. A base 100 is disposed, and a pair of rubber cushions 102 are disposed on the two side flaps 101 of the base 100, and the base 100 is fixed to the reverse osmosis water filter by a fixing screw 103 and a nut 104, or a bath in a travel car. The outer casing C of the kitchen water supply device; however, the effect of using the two pairs of rubber cushions 102 on the side flaps 101 of the base 100 to achieve the shock absorption is rather limited, and the vibration of the pump body caused by the pump body is extremely strong. It still causes the resonance of the outer casing C to make an annoying sound, and is connected to the pump head cover. The water pipe P on the water outlet 22 will also sway synchronously with the frequency of the smashing smash (as shown by the imaginary line P in Fig. 14 and its a view) and slap into the adjacent reverse osmosis water purifier. If the component is used for a period of time, the sway between the water pipe P and its pipe joint will gradually loosen each other, and finally the result of water leakage will result in the above-mentioned many defects due to the actuation of the four-pressure diaphragm pump. 〝 〝 〝 , , , , , , , , , , , , 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 。 。 。 。 。 。 。 。 。 。

SUMMARY OF THE INVENTION The main object of the present invention is to provide a "damping structure of a four-charged diaphragm pump" in which an arc is recessed downwardly around the periphery of each of the actuating perforations in the top surface of the pump head of the four-pressure diaphragm pump. Forming a groove, and on the bottom surface of the diaphragm opposite to each arcuate groove, an arcuate protrusion is protruded downward so that the bottom surface of the diaphragm piece and the top surface of the pump head seat are adhered to each other, the diaphragm Each of the curved bumps on the bottom surface of the sheet is completely embedded in each of the arcuate grooves on the top surface of the pump head, and a short arm length is formed between the arcuate bumps on the bottom surface of the diaphragm and the positioning cam. When the balance wheel pushes up the bottom surface of the diaphragm to multiply the shorter force arm length, the generated torque becomes smaller, and the shock 〞 strength of the four plenum diaphragm pump is greatly reduced.

Another object of the present invention is to provide a "damping structure of a four-pressure diaphragm pump", in which four arcuate projections protruding from the bottom surface of the diaphragm are embedded in four concave concaves recessed in the top surface of the pump head. In the slot, the shorter arm length is formed, and the shock enthalpy strength of the plenum diaphragm pump can be greatly reduced when the four plenum diaphragm pump is actuated, so that the four plenum diaphragm pump is installed on the base with the rubber cushion. And it is fixed on the outer casing of the reverse osmosis water purifier or the bathroom water supply equipment in the travel car, and it will not resonate with the outer casing and make an annoying sound.

As shown in FIG. 15 to FIG. 22, the "damping structure of the four-charged diaphragm pump" of the present invention is shown in FIG. In the first embodiment, a curved groove 65 is recessed downwardly on the top surface of the pump head holder 60 near the periphery of each of the actuating perforations 61, and a diaphragm is disposed at a position corresponding to each of the arcuate grooves 65. On the bottom surface of the sheet 70, an arcuate projection 77 (shown in FIGS. 20 and 21) is protruded downward, so that the bottom surface of the diaphragm sheet 70 and the top surface of the pump head holder 60 are adhered to each other, and the bottom surface of the diaphragm sheet 70 is bottomed. The four arcuate projections 77 are completely embedded in the four arcuate recesses 65 on the top surface of the pump head holder 60, and form a shorter gap between the arcuate projections 77 on the bottom surface of the diaphragm piece 70 and the positioning collar block 76. The arm length L2 (shown in an enlarged view in Fig. 22).

As shown in FIG. 23, FIG. 24 and FIG. 13, the above-described first embodiment of the present invention is supercharged. When the cavity diaphragm pump is actuated, due to the length L2 of the arm between the curved protrusion 77 on the bottom surface of the diaphragm 70 and the positioning convex block 76 (as shown in FIG. 24), it is smaller than the outer rib in the conventional four-pressure diaphragm pump. The force arm length L1 between the 71 and the positioning collar block 76 (as shown in FIGS. 13 and 24), so the force F of the balance 52 pushing up the bottom surface of the diaphragm 70 is multiplied by the shorter arm length L2. The generated torque (ie, the torque = F × L2) is also relatively small. Therefore, the four arcuate projections 77 projecting from the bottom surface of the diaphragm 70 are embedded in the four arcs concave on the top surface of the pump head holder 60. The groove 65 can reduce the moment effect of pushing up the force F by each of the balance wheels 52, thereby achieving the intensity of greatly reducing the shock 〞, and the result of the test sample shows that the strength of the 〝 vibration of the present invention is only known. One tenth or less of the four plenum diaphragm pump, and the conventional base 100 is first installed on the pump body of the present invention, and then fixed to the outer casing C of the reverse osmosis water filter or the bathroom water supply equipment of the travel car. After the up (as shown in Figure 14), there is no resonance at all and the annoying sound caused by it.

As shown in FIGS. 25 and 26, in the first embodiment of the present invention, the pump head holder 60 is provided. Each arcuate recess 65 on the top surface can be modified to be provided as an arcuate bore 64.

As shown in FIG. 27 and FIG. 28, in the first embodiment of the present invention, the top surface of the pump head holder 60 is provided. Each arcuate groove 65 (shown in Figures 16 and 17) can be further modified to be formed as an arcuate bump 651 (as shown 27, and corresponding to each of the arcuate protrusions 77 (shown in FIGS. 20 and 21) of the bottom surface of the diaphragm 70, are also synchronously changed into arcuate grooves 771 (as shown in FIG. 27), After the bottom surface of the diaphragm piece 70 and the top surface of the pump head holder 60 are fitted to each other, each of the arcuate projections 651 on the top surface of the pump head holder 60 is completely embedded in each of the arcuate grooves 771 of the bottom surface of the diaphragm piece 70 ( As shown in FIG. 28, it can still form a shorter arm length L3 between the arcuate groove 771 on the bottom surface of the diaphragm 70 and the positioning collar block 76 (as shown in an enlarged view in FIG. 28), and It also has the effect of greatly reducing the vibration of the sputum.
