The three phases are screwed together and directly screwed into the fixed perforations 33 in the motor front cover 30 to complete the combination of the entire four plenum diaphragm pumps (as shown in Figures 1 and 9).

As shown in FIG. 12 and FIG. 13 , it is the operation mode of the above-mentioned conventional four-pressure chamber 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 balance wheel housing 50 is The four balance wheels 52 sequentially generate up and down reciprocating motions, and the four piston actuating regions 74 on the diaphragm 70 are also actuated by the four balance wheels 52, which are pushed up and down in synchronization. And the reverse up and down displacement occurs, so when the balance 52 is actuated downward, the synchronization will be separated. The piston actuating region 74 of the diaphragm 70 and the piston pusher block 80 are pulled downward, so that the piston piece 98 of the piston valve body 90 is pushed open, and the tap water W from the water inlet port 21 of the pump head cover 20 is pressurized by the water inlet hole 97. In the chamber 26 (as indicated by the arrow W in Fig. 12 and its enlarged view); when the balance 52 is pushed up, the piston actuation zone 74 and the piston pusher 80 of the diaphragm 70 are simultaneously synchronized. The top and the water in the pressurizing chamber 26 are squeezed to increase the water pressure to between 100 psi and 150 psi, so that the boosted high pressure water Wp can push the check rubber pad 94 on the drain seat 92 away. And through the drain holes 95 of the drain seat 92, sequentially flow into the high pressure water chamber 27, and then discharged through the water outlet 22 of the pump head cover 20 outside the four plenum diaphragm pump (as shown in FIG. 13 and its enlarged view) The arrow Wp), in turn, provides 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 output of the bath water supply device in the passenger car.

As shown in FIG. 14 and FIG. 15, the conventional four-pressure diaphragm diaphragm pump has a serious defect for a long time. When it is actuated, the four balance wheels 52 will alternately push up the piston actuation region 74 of the diaphragm 70. It is equal to the position of the four piston actuating regions 74 on the bottom surface of the diaphragm 70, and an upward force F (shown in FIG. 15) is continuously applied, and the external force 71 and the positioning convex are multiplied by the force F. The torque generated by the length L1 of the arm between the ring blocks 76 (ie, the torque = F × L1) causes the entire pump body to vibrate. Since the output speed of the motor 10 is as high as 800-1200 rpm, it drives four The intensity of the 〝 vibration generated by the rotation of the balance wheel 52 has been high.

Therefore, as shown in FIG. 16 , a conventional four-pushing chamber diaphragm pump is provided with a base 100 on the outer edge of the pump, and a pair of rubber cushions 102 are disposed on the two side flaps 101 of the base 100, and then The fixing screw 103 and the nut 104 fix the base 100 to the reverse osmosis water filter or the outer casing C of the kitchen water supply device in the traveling car; however, in fact, two pairs of rubber shock absorbers on the side flaps 101 of the base 100 are utilized. The effect of the cushion 102 to achieve shock absorption is rather limited, and the vibration caused by the pump body is 〞 The strength is extremely high, and the sound of the outer casing C is still generated to cause an annoying sound. In addition, the water pipe P connected to the water outlet 22 of the pump head cover 20 also oscillates synchronously with the frequency of the cymbal vibration (see Fig. 16 The imaginary line P in the a view) is slapped to other components in the adjacent reverse osmosis water purifier. If it is used for a period of time, the water pipe P and its pipe joints will gradually loosen each other due to swaying. In the end, it will lead to the result of water leakage. Many of the above defects are caused by the 〝 vibration caused by the operation of the four plenum diaphragm pump. Therefore, how to greatly reduce the 〝 vibration loss caused by the operation of the four plenum diaphragm pump has been It has become a very urgent issue to be solved.

As shown in FIG. 17 and FIG. 18, when the above four plenum diaphragm pump is actuated, since the four cylindrical balance wheels 52 are pushed by the rotation of the tilt eccentric cam 40, the diaphragm 70 is also pushed up and pushed upward. Each of the piston actuating regions 74 is equal to the position of the four piston actuating regions 74 on the bottom surface of the diaphragm 70, and an upward force F is continuously applied, and the bottom surface of the diaphragm 70 is topped up by the force F each time. When pushed, the downward bucking force Fs is also generated synchronously, and the magnitude distribution of the force acts on the diaphragm piece 70 located in each piston actuating zone 74 (as shown by the distribution arrow of each size rebounding force Fs in FIG. 18) At the same time, the bottom surface of the diaphragm 70 located at the position of the four piston actuating regions 74 is crushed, and the contact between the horizontal top surface 53 and the round corner 57 in the cylindrical balance 52 is contacted. The bottom surface position P of the diaphragm piece 70 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, each of the piston actuating regions 74 of the diaphragm 70 is The bottom position P is subjected to at least 4 times of extrusion per second, and At such a high frequency of extrusion times, the bottom surface position P of the diaphragm 70 is the earliest position where cracking occurs, and the main reason why the entire four-pressure diaphragm pump can no longer operate normally and reduce its service life is caused. Therefore, how to eliminate the bottom surface of the piston actuating region 74 of the diaphragm piece 70 is easily broken by the high frequency pushing and pushing of the cylindrical balance wheel 52, which is another problem that needs to be solved urgently.

The main object of the present invention is to provide a "damper structure and balance structure improvement of a four-charged diaphragm pump", which is a peripheral direction of each of the actuating perforations in the top surface of the pump head seat in the four-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 forms a short between the curved bumps on the bottom surface of the diaphragm and the positioning cam. The length of the arm, and thus the force of pushing the diaphragm to push up the bottom surface of the diaphragm multiplied by the length of the shorter arm, the generated torque becomes smaller, and the shock of the four-pilot diaphragm pump is greatly reduced. strength.

Another object of the present invention is to provide a "damper structure and balance structure improvement of a four-charged diaphragm pump", in which four arcuate projections protruding from the bottom surface of the diaphragm are embedded in the recessed surface of the pump head. In the four curved grooves, the shorter arm length is formed, which can greatly reduce the strength of the 〝 〝 when the four plenum diaphragm pump is actuated, so that the four plenum diaphragm pump is installed in the conventional rubber reduction After the base of the cushion is fixed on the outer casing of the reverse osmosis water purifier or the bathing water supply equipment in the travel car, it will not resonate with the outer casing and make an annoying sound.

A further object of the present invention is to provide a "damper structure of a four-charged diaphragm pump and an improved structure of a balance wheel", which is to position a circular groove on a horizontal top surface of each cylindrical balance in the balance wheel seat to The area of the vertical side surface is provided with a downward slope so that after the motor output shaft of the four-pressure diaphragm pump rotates, the four 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 causes an upwardly inclined state of the diaphragm body between the positioning collar and the outer rib in the diaphragm, by positioning the circle on the horizontal top surface of each cylindrical balance The downward slope of the ring groove to the vertical side surface can be completely flatly supported on the bottom surface of the diaphragm actuating region of the diaphragm in the diagonally pulled state, without causing squeezing and squeezing of the diaphragm bottom surface of the diaphragm piston. Therefore, the rounding of the cylindrical balance wheel in the conventional four-pressure diaphragm pump can be completely eliminated, and the high-frequency extrusion of the bottom surface of the diaphragm piston working area is easily broken, thereby greatly increasing the diaphragm to bear the cylindrical balance. High frequency push-to-force tolerance and effectively extend the life of the entire four-bore diaphragm pump.

Still another object of the present invention is to provide a "damper structure of a four-charged diaphragm diaphragm pump and a structure improvement of a balance wheel", which is to position a circular groove on a horizontal top surface of each cylindrical balance in the balance wheel seat to The area of the vertical side surface is provided with a downward slope so that after the motor output shaft of the four-pressure diaphragm pump rotates, the four 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 causes the diaphragm sheet in the diaphragm to be inclined upwardly from the positioning collar to the outer rib, and the annular groove is positioned on the horizontal top surface of each cylindrical balance to The downward slope of the vertical side surface can be completely flatly supported on the bottom surface of the diaphragm in the diagonally pulled state, without causing squeezing and squeezing of the diaphragm surface of the diaphragm piston, so that the diaphragm is subjected to the upward action. After the force, the rebound force generated by the synchronization is greatly reduced, so the working current load and the operating 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 and poor noise. , In addition to ensuring that all the bearings in the diaphragm booster pump functioning smoothly, but also reduce the operating current Yin Mada reduce spending power and electricity, while both extend the life of the entire diaphragm booster pumps and other multiple benefits.

As shown in FIG. 19 to FIG. 28, in the first embodiment of the present invention, the "damper structure of the four-pressure chamber diaphragm pump and the structure of the balance wheel" is improved, and the top surface of the pump head holder 60 is moved around each of the tops. An arcuate recess 65 (shown in FIGS. 20 to 22) is recessed downwardly from the periphery of the through hole 61, and an arc is protruded downward on the bottom surface of the diaphragm 70 corresponding to the position of each arcuate recess 65. Shaped bumps 77 (shown in Figures 24 and 25), such that the bottom surface of the diaphragm 70 and the top surface of the pump head holder 60 are fitted to each other, and the four arcuate projections 77 on the bottom surface of the diaphragm 70 are completely embedded in the pump. The four arcuate recesses 65 in the top surface of the headstock 60 form a shorter arm length L2 between the arcuate bumps 77 on the bottom surface of the diaphragm 70 and the positioning collar block 76 (as shown in FIG. 28). As shown in the figure, the area of the horizontal top surface 53 of each of the cylindrical balances 52 of the balance wheel housing 52 that is positioned on the concave ring groove 55 to the vertical side surface 56 is further provided as a downward slope 58 (see FIG. 26 and FIG. 27)).

As shown in FIG. 29, FIG. 30 and FIG. 15, when the four plenum diaphragm pump is actuated, due to the length L2 of the arm between the curved projection 77 on the bottom surface of the diaphragm 70 and the positioning collar block 76 (as shown in FIG. 30) is smaller than the length L1 of the arm between the outer rib 71 and the locating ring block 76 of the diaphragm 70 (as shown in FIGS. 15 and 30), so the cylindrical balance 52 pushes up the bottom surface of the diaphragm 70 upward. The force F is multiplied by the shorter arm length L2, and the generated torque (i.e., 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. The four arcuate grooves 65 recessed in the top surface of the pump head block 60 can reduce the moment effect of pushing up the force F of each of the cylindrical balance wheels 52, thereby greatly reducing the strength of the shock 〞, after the actual sample is tested. The results show that the 〝 vibration 〞 strength of the present invention is only one tenth of that of the conventional 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 reverse osmosis. On the outer casing C of the water purifier or the bathroom water supply equipment in the travel car (as shown in Figure 16), there is no resonance at all and the resulting People sound.

Further, as shown in FIGS. 31 to 33, when the first embodiment of the "damper structure and balance structure improvement of the four-pilot diaphragm pump" of the present invention is actuated, the four cylindrical balance wheels 52 are rotated by the tilt eccentric cam 40. After pushing up the bottom surface of the diaphragm 70 of the piston actuating region 74, the upward force F causes the diaphragm body between the positioning ring block 76 and the outer rib 71 in the diaphragm 70 to be inclined upward. By positioning the concave ring groove 55 on the horizontal top surface 53 of the cylindrical balance 52 to the downward inclined surface 58 of the vertical side surface 56, the diaphragm piece 70 in the obliquely pulled state can be completely flushed and supported at the same time. On the bottom surface of the region 74, there is no phenomenon that the bottom surface of the piston actuating region 74 of the diaphragm 70 is crushed (as shown in Figs. 31 and 32), and the rebound force Fs generated by the diaphragm 70 is also followed. The large reduction (as shown by the arrow distribution of each size rebound force Fs in FIG. 32, compared with the magnitude rebound force Fs in FIG. 18, it can be seen that the present invention can make the diaphragm sheet 70 synchronously produce a rebound effect. The force Fs is greatly reduced), and therefore, by the horizontal top surface 5 of the cylindrical balance 52 of the present invention 3, the downward inclined surface 58 of the positioning concave ring groove 55 to the vertical side surface 56, in addition to completely eliminating the rounding 57 of the cylindrical balance 52 in the conventional four-pressure diaphragm pump, the piston operating region 74 of the diaphragm 70 The high-frequency 〝 〞 〝 外 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( Therefore, the diaphragm piece 70 can greatly improve the tolerance of the high-frequency pushing action of the cylindrical balance wheel 52, and can effectively reduce the working current load and the working temperature of the motor, thereby preventing the lubricating oil in the motor bearing from being evaporated to a high temperature. The lack of lubrication leads to the loss of abnormal sound, in addition to ensuring that all the bearings in the four-pilot diaphragm pump are running smoothly, and the power consumption of the motor is reduced due to the reduced operating current of the motor, and the entire four-pressurization is extended.

The region of the concave ring groove 505 to the inwardly inclined side surface 506 is provided with a downward slope 508.

As shown in FIG. 116 to FIG. 118, when the ninth embodiment of the "damper structure and balance structure improvement of the four-pilot diaphragm pump" of the present invention is actuated, the four cylindrical balance wheels 502 are rotated by the tilt eccentric cam 40. When the bottom surface of the diaphragm 70 of the piston actuating region 74 is pushed up, the upward force F causes the diaphragm body between the positioning ring block 76 and the outer rib 71 in the diaphragm 70 to be inclined upward. By positioning the concave ring groove 505 on the horizontal top surface 503 of the cylindrical balance 502 to the downward inclined surface 508 of the inwardly inclined side surface 506, the bottom surface of the diaphragm 70 can be completely flatly contacted and supported at the same time. Above, without causing squeezing of the bottom surface of the diaphragm 70 of the diaphragm 70 (such as As shown in FIGS. 116 and 117), the rebound force Fs generated by the diaphragm 70 is also greatly reduced (as indicated by the arrow distribution of each size rebound force Fs in FIG. 117), and the side edges are inclined inward. The design of the surface 506 can avoid the impact of the cylindrical balance wheel 502 after the diameter of the cylinder 502 is increased, and can avoid the wall surface of the hole of the pumping head 60. The concave ring groove 505 is positioned on the horizontal top surface 503 of the wheel 502 to the downward slope 508 of the inwardly inclined side surface 506, except that the round 57 pair of the cylindrical balance 502 in the conventional four-pressure diaphragm pump can be completely eliminated. The piston actuation area 74 on the bottom surface of the diaphragm 70 produces a defect in the squeezing squeegee (as shown by the imaginary line portion in Fig. 118), and has a rebound force Vs which is synchronously generated after the diaphragm 70 is subjected to the upward force F. The effect of the diaphragm 70 can greatly improve the tolerance of the high-frequency thrust of the cylindrical balance 502, thereby effectively extending the service life of the entire four-pressure diaphragm pump. In addition, since the diameter of the cylindrical balance 502 is increased, the area of the downward inclined surface 508 is also increased, so that the area of the bottom surface of the diaphragm sheet 70 which is in contact with the obliquely pulled state can be increased during the operation (as shown in FIG. A shows), and increases the support of the rebound force Fs, thereby reducing the degree of influence of the diaphragm 70 on the rebound force Fs, and also prolonging the service life of the diaphragm 70.

After 511, a positioning concave ring groove 515 (shown in FIGS. 121 and 122) can be formed between the convex cylinder 513 and the upper step hole 523.

As shown in FIG. 123 to FIG. 126, after the balance ring 521 is engaged with the cylindrical seat 511, the four positioning convex ring blocks 76 on the bottom surface of the diaphragm 70 are respectively inserted into the four cylinders of the balance wheel holder 500. The positioning groove 515 of the balance wheel 502 is inserted into the stepped hole 81 of the piston push block 80 by the fixing screw 1 and passes through the central through hole 75 of the four piston actuating regions 74 of the diaphragm 70. The diaphragm piece 70 and the four-piston push block 80 are simultaneously screwed into the threaded holes 514 of the cylindrical seat 511 of the four-cylinder balance 502 in the balance wheel holder 500 (as shown in an enlarged view in FIG. 123); when the output shaft of the motor 10 is output When the four cylindrical balance wheels 502 are rotated by the tilting eccentric cam 40 to push up the bottom surface of the diaphragm 70 of the piston actuating region 74, the upward force F causes the positioning of the convex ring block 76 in the diaphragm 70 to The diaphragm body between the outer ribs 71 produces an upwardly inclined state by the positioning of the concave ring groove 515 of the balance ring 521 of the cylindrical balance 502 to the downward slope 526 of the inwardly inclined side surface 522, At the same time, it can be completely flatly contacted and supported on the bottom surface of the diaphragm sheet 70 in the diagonally pulled state without causing squeezing of the bottom surface of the diaphragm sheet 70. The phenomenon (as shown in FIG. 124 and FIG. 125), and the rebound force Fs generated by the diaphragm 70 is also greatly reduced (as shown by the arrow distribution of the rebound force Fs of each size in FIG. 125). The design structure of the inwardly inclined side surface 522 can still avoid the impact on the wall surface of the pump head 60 to actuate the hole 61 when the diameter of the cylindrical balance 502 is increased. In addition to completely eliminating the lack of the 倒 〞 〞 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( After the diaphragm 70 is subjected to the upward force F, the rebound generating force Fs is synchronously reduced, so that the diaphragm 70 can greatly improve the tolerance of the cylindrical balance 502 to the high frequency pushing effect, and thus Effectively extending the service life of the entire four plenum diaphragm pump, and having the balance ring 521 having the inwardly inclined side surface 522 and the downward slope 526, except for the same effect as the second embodiment described above, The feasibility of stripping must be considered in the production, so it can be made separately from the balance wheel holder 500, which can save the manufacturing cost, and the cylindrical seat 511 can be made integrally with the balance wheel holder 500, and then two The combination is combined into a cylindrical balance 502.
