As shown in FIG. 12 and FIG. 13, it is the operation of the above-mentioned conventional five-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 five balance wheels 52 on the balance wheel housing 50 are sequentially generated to reciprocate up and down, and the five on the diaphragm 70 The piston actuation zone 74 is also actuated by the up-and-down actuation of the five balance wheels 52. The synchronization is pushed up and down to produce a reverse up and down displacement. Therefore, when the balance 52 is actuated downward, the diaphragm 70 is synchronized. The piston actuating area 74 and the piston push block 80 are pulled down, so that the piston piece 98 of the piston valve body 90 is pushed. Opening, 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. 12 and its enlarged view); when the balance wheel 52 is up During the pushing action, the piston actuating zone 74 and the piston pushing block 80 of the diaphragm 70 are simultaneously topped up, and the water in the pressurizing 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 through the high-pressure water chamber 27, and then through The water outlet 22 of the pump head cover 20 is discharged outside the five plenum diaphragm pump (as indicated by the arrow Wp in FIG. 13 and its enlarged view), thereby providing a reverse osmosis filtration device for the RO membrane tube in the large commercial reverse osmosis water filter. The required water pressure, or the water pressure required to output the bath and water supply equipment in the RV.

As shown in FIG. 14 and FIG. 15, the above-mentioned conventional five-pressure diaphragm diaphragm pump has existed for a long time. A serious deficiency, when it is actuated, the five balance wheels 52 will alternately push up the piston actuation zone 74 of the diaphragm 70, which is equal to the position of the five 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 five balance wheels 52 in rotation is always high.

Therefore, as shown in Figure 16, the conventional five-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. 16 and its a view) and slap into the adjacent reverse osmosis water purifier. If the component is used for a period of time, the sloshing 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 operation of the five plenum diaphragm pump. 〝 〝 〝 , , , , , , , , , , , , 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 〝 。 。 。 。 。 。 。

17 and FIG. 18, when the above five plenum diaphragm pump is actuated, When the five cylindrical balance wheels 52 are pushed by the rotation of the tilting eccentric cam 40, they will also alternately push up each piston actuating region 74 of the diaphragm 70, so that it is equal to the five piston actuating regions on the bottom surface of the diaphragm 70. At the position 74, an upward force F is continuously applied, and each time the bottom surface of the diaphragm 70 is pushed up by the force F, a downward rebound force Fs is synchronously generated, and the magnitude distribution of the force acts on Located on the diaphragm 70 of each piston actuating zone 74 (as indicated by the distribution arrows of the resizing forces Fs of the various sizes in Fig. 18), the bottom surface of the diaphragm 70 located at the position of the five piston actuating zones 74 is squeezed. The phenomenon of pressing, wherein the bottom surface position P of the diaphragm piece 70 which is in contact with the horizontal top surface 53 and the round corner 57 in the cylindrical balance 52 is subjected to the maximum degree of compression (as shown in FIG. 18). Therefore, at the rotational speed of the output shaft 11 of the motor 10 as high as 800-1200 rpm, the bottom surface position P of each piston actuation region 74 in the diaphragm 70 is subjected to at least four compressions per second, and is at such a high frequency. Under the number of extrusions, the bottom surface of the diaphragm 70 is caused P is the earliest position where the rupture occurs, and also causes the entire five plenum diaphragm pump to be unable to operate normally and reduce the service life thereof. Therefore, how to eliminate the bottom surface of the piston plate actuation region 74 of the diaphragm 70 is affected by the cylindrical balance 52. The lack of easy breakage caused by high-frequency push-pull extrusion is another problem that needs to be solved urgently.

Continued as shown in Fig. 19 to Fig. 21, the piston valve body in the conventional five-pressure diaphragm pump In another embodiment of the 900, a ring-shaped bead 901 is protruded downwardly from the outer peripheral side of the bottom portion, and the gap between the outer rib 71 and the inner rib 72 in the diaphragm 70 is inserted into the diaphragm sheet 70 toward the pump head cover 20. A circular drain seat 902 is defined in the central position, and a positioning hole 903 is formed in the center of the five regions formed by the angle of the angle of 72 degrees on the drain seat 902, so that a T-shaped piston piece 904 can be inserted and fixed. In addition, a plurality of drainage holes 905 (shown in FIG. 19) are disposed on the position between each positioning hole 903 and the drain seat 902, and corresponding to the outer surface of the drain seat 902 of each area, respectively Five water inlets 906 are arranged at an angle of 72 degrees and each of the openings are downwardly facing, and a plurality of water inlet holes 907 are inserted in each water inlet seat 906, and are in the center of each water inlet seat 906. An inverted T-shaped piston piece 904 is disposed, wherein the drainage holes 905 in each area of the drainage seat 902 respectively communicate with each of the corresponding water inlet seats 906, and the ring protrusion 901 at the bottom of the piston valve body 900 After the plug is placed in the gap between the outer rib 71 of the diaphragm 70 and the inner rib 72, it can be inserted in each Between the seat 906 and the top surface of the diaphragm 70, a closed plenum chamber 26 (shown in FIG. 21) is formed, and after the pump head cover 20 covers the top surface of the piston valve body 900, the convex ring The bottom of the bottom portion 25 is pressed against the outer peripheral surface of the drain seat 902 of the piston valve body 900 such that the inner wall surface of the convex ring 25 and the drain seat 902 of the piston valve body 900 can surround a high pressure water chamber 27 . (As shown in FIG. 21), the fixing bolts 2 respectively pass through the fixing through holes 23 of the pump head cover 20, and pass through the respective fixing through holes 63 of the pump head holder 60, and are respectively placed in the pump head holder 60. The nut 3 in the fixed through hole 63 is screwed together, and directly screwed into each fixed through hole 33 in the motor front cover 30, thereby completing the combination of the entire five plenum diaphragm booster pump (as shown in FIG. 1 and FIG. 21). ).

As shown in FIG. 21, when the output shaft 11 of the motor 10 is rotated, the tilting eccentricity is driven. The cam 40 rotates, and at the same time, the five balance wheels 52 on the balance wheel seat 50 sequentially generate an up and down reciprocating motion, and the five piston actuation regions 74 on the diaphragm piece 70 are also subjected to the upper and lower sides of the five balance wheels 52. Actuate, The synchronization is pushed up and down to generate a reverse up and down displacement. Therefore, when the balance 52 is actuated downward, the piston actuation zone 74 and the piston pusher 80 of the diaphragm 70 are simultaneously pulled down, so that the piston valve body 900 The piston piece 904 of the intermediate inlet 906 is pushed open, and the tap water W from the water inlet 21 of the pump head cover 20 is introduced into the plenum chamber 26 via the water inlet hole 907 (as indicated by an arrow W in FIG. 21); When the balance wheel 52 pushes up, the piston actuating zone 74 and the piston pusher block 80 of the diaphragm 70 are simultaneously topped up, and the water in the pressurizing chamber 26 is squeezed to increase the water pressure. Between 100 psi and 150 psi, the pressurized high pressure water Wp can push the piston piece 904 on the drain seat 902 away, and continuously flow into the high pressure water chamber 27 through the drain holes 905 of the drain seat 902. Then, the water outlet 22 of the pump head cover 20 is discharged outside the five-pressure chamber diaphragm pump (as indicated by an arrow Wp in FIG. 21), thereby providing the water pressure required for the reverse osmosis filtration of the RO membrane tube in the reverse osmosis water filter. Or the water pressure required for the kitchen water supply equipment in the RV.

The fifth plenum diaphragm pump of the piston valve body 900 of the other conventional embodiment is the same There is a great loss of vibration when it is actuated. Therefore, how to greatly reduce the lack of vibration and vibration is also an urgent problem to be solved.

The main object of the present invention is to provide a "damper structure and balance structure improvement of a five-pressure chamber diaphragm pump", which is a peripheral direction of each of the actuating perforations in the top surface of the pump head seat in the five-pilot diaphragm pump. An arcuate groove is formed in the recess, and an arcuate protrusion is protruded downwardly on the bottom surface of the diaphragm corresponding to the position of each arcuate groove, so that the bottom surface of the diaphragm and the top surface of the pump head are attached to each other. After the combination, each of the curved bumps on the bottom surface of the diaphragm is completely embedded in each of the arcuate grooves on the top surface of the pump head, and is formed between the curved bumps on the bottom surface of the diaphragm and the positioning convex block. The length of the arm, such that the force of the balance pushing up the bottom of the diaphragm multiplied by the length of the shorter arm After that, the generated torque becomes small, and the shock enthalpy strength when the five plenum diaphragm pump is actuated is greatly reduced.

Another object of the present invention is to provide a "damping structure of a five-charged diaphragm pump" And the structure of the balance wheel is improved, the five curved protrusions protruding from the bottom surface of the diaphragm are embedded in the five arcuate grooves recessed in the top surface of the pump head, and the shorter arm length is formed, which can be increased in five When the pressure chamber diaphragm pump is actuated, the strength of the shock absorber is greatly reduced, so that the five-pressure diaphragm pump is installed on a base with a rubber cushion and is fixed to a large commercial reverse osmosis water purifier or The outer shell of the bathing and drinking water supply equipment in the travel car does not resonate with the outer casing and makes an annoying sound.

A further object of the present invention is to provide a "damping structure of a five-charged diaphragm pump" And the structure of the balance wheel is improved, which is to set the area of the circular groove on the horizontal top surface of each of the balance wheels in the balance wheel to the vertical side surface to form a downward slope, so that the five-pressure diaphragm pump After the motor output shaft rotates, when the five cylindrical balance wheels are rotated by the tilting eccentric cam to push up the bottom surface of the diaphragm of the piston actuation region, the upward force will cause the convex ring to be positioned in the diaphragm to the outer rib. The diaphragm body between the two forms an upwardly inclined state, and the downward inclined surface of the circular groove to the vertical side surface of each of the cylindrical balance wheels can be completely flatly supported in the oblique state at the same time. The diaphragm piece is on the bottom surface of the piston actuating area, and does not cause squeezing and squeezing of the bottom surface of the diaphragm piston working area, so that the rounding of the cylindrical balance wheel in the conventional five-pressure diaphragm pump can be completely eliminated. The high frequency extrusion of the bottom surface of the piston working area is caused by the lack of easy cracking, which can greatly improve the tolerance of the diaphragm piece to the high frequency pushing effect of the cylindrical balance wheel, and effectively extend the service life of the entire five-pressure chamber diaphragm pump.

Still another object of the present invention is to provide a shock absorbing structure of a "five-booster diaphragm pump" And the structure of the balance wheel is improved, which is to locate the annular concave surface on the horizontal top surface of each cylindrical balance wheel in the balance wheel seat The area from the groove to the vertical side surface is formed as a downward slope, so that after the motor output shaft of the five-pressure diaphragm pump is rotated, the five cylindrical balance wheels are subjected to the inclined eccentric cam rotation to push up the diaphragm of the piston actuation region. When the bottom surface is pressed upward, the diaphragm body between the positioning cam and the outer rib in the diaphragm piece is inclined upward, and the annular top surface is positioned by the horizontal top surface of each cylindrical balance wheel. The downward slope of the groove to the vertical side surface can be completely flatly supported on the bottom surface of the diaphragm piece in the diagonally pulled state without causing squeezing and squeezing of the diaphragm bottom surface of the diaphragm piece, so that the diaphragm piece is subjected to After the upward force, the synchronous rebound force is greatly reduced, so the working current load and the working temperature of the motor can be effectively reduced, and the lubricating oil in the motor bearing does not cause high temperature evaporation, resulting in poor lubrication. The lack of, in addition to ensuring the smooth operation of all the bearings in the diaphragm booster pump, but also reduce the power and electricity expenses due to the reduced operating current of the motor, while extending the entire diaphragm booster pump Life and other multiple benefits.
