The nut 3 in the 63 is screwed and directly screwed into the fixed perforations 33 in the motor front cover 30 to complete the combination of the entire diaphragm booster pump (as shown in Figures 1 and 11).

As shown in FIG. 12 and FIG. 13, it is the operation mode of the above-mentioned conventional diaphragm booster pump. When the output shaft 11 of the motor 10 rotates, the tilting eccentric cam 40 is rotated, and at the same time, three of the balance wheel seats 50 are provided. The cylindrical balance wheel 52 sequentially generates up and down reciprocating motions, and the three piston actuating regions 74 on the diaphragm piece 70 are also actuated by the three cylindrical balance wheels 52, which are pushed up and down in synchronization. And the reverse up and down displacement is generated, so when the cylindrical balance 52 is actuated downward, the same Stepping the piston actuation zone 74 of the diaphragm 70 and the piston pusher 80 downward, the piston piece 98 of the piston valve body 90 is pushed open, and the tap water W from the water inlet 21 of the pump head cover 20 is passed through the water inlet hole 97. In the plenum chamber 26 (as indicated by the arrow W in FIG. 12 and its enlarged view); when the cylindrical balance 52 is pushed up, the piston actuation zone 74 and the piston push block of the diaphragm 70 are simultaneously synchronized. 80 is topped up, and the water in the pressurizing chamber 26 is squeezed to increase the water pressure to between 80 psi and 100 psi, so that the pressurized high pressure water Wp can be used as the check rubber on the drain seat 92. The pad 94 is pushed open, and continuously flows into the high pressure water chamber 27 through the drain holes 95 of the drain seat 92, and then exits the diaphragm booster pump through the water outlet 22 of the pump head cover 20 (as shown in FIG. 13 and its enlarged view). The arrow Wp in the view) provides the water pressure required for reverse osmosis filtration of the RO membrane tube in the reverse osmosis water filter.

As shown in FIG. 14 to FIG. 16, the conventional diaphragm booster pump has a serious defect for a long time. When it is actuated, the three cylindrical balance wheels 52 will alternately push up the piston actuating region 74 of the diaphragm 70. It is equal to the position of the three 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 ring are multiplied by the force F. The torque generated by the arm length L1 between the blocks 76 (ie, the torque = F × L1) causes the entire pump body to vibrate. At the output shaft 11 of the motor 10, the speed is as high as 700-1200 rpm, and three cylindrical pendulums are placed. The intensity of the 〝 vibration generated by the rotation of the wheel 52 has been high.

Therefore, the conventional diaphragm booster pump is provided with a base 100 (shown in FIG. 16) on the outer edge of the pump. The two side flaps 101 of the base 100 are respectively provided with a pair of rubber cushions 102, and then the fixing screws 103 are provided. And the nut 104 fixes the base 100 to the outer casing C of the reverse osmosis water filter; however, the effect of using the two pairs of rubber cushions 102 on the side flaps 101 of the base 100 to achieve shock absorption is rather limited. The shock vibration generated by the pump body is extremely strong, and still causes the resonance of the outer casing C to make an annoying sound. In addition, the water pipe P connected to the water outlet 22 of the pump head cover 20 will also follow the shock. The frequency of the turbulence, synchronous sloshing (as shown by the imaginary line P in Fig. 16), slaps the other components in the adjacent reverse osmosis water purifier, and if used for a period of time, the water pipe P and its pipe joint are also As the swaying of the sway gradually causes mutual looseness, and finally the result of water leakage, the above-mentioned many defects are caused by the turbulent vibration caused by the diaphragm booster pump operation, so how can the diaphragm booster pump actuation be greatly reduced? The lack of vibration is indeed a very urgent issue to be solved.

As shown in FIG. 17 and FIG. 18, when the above-mentioned conventional diaphragm booster pump is actuated, since the three cylindrical balance wheels 52 are pushed by the rotation of the tilting eccentric cam 40, the diaphragms 70 are pushed up and pushed up. A piston actuating zone 74 is equal to the position of the three piston actuating zones 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 pushed up by the force F each time. 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 indicated 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 three piston actuating regions 74 is crushed, and in turn, the diaphragm is in contact with the horizontal top surface 53 and the rounded corner 57 in the cylindrical balance 52. 70 bottom position P, which is subjected to the greatest degree of squeezing (as shown in Fig. 18), therefore, the bottom surface position of each piston actuating region 74 in the diaphragm 70 at the rotational speed of the output shaft 11 of the motor 10 is as high as 700-1200 rpm. P will be squeezed at least 4 times per second, but at the same time The high frequency of the number of extrusions, that is, the bottom surface position P of the diaphragm 70 is the earliest position where the crack occurs, and also causes the entire diaphragm booster pump to be unable to operate normally and reduce the service life thereof, so how to exempt The bottom surface of the diaphragm actuating region 74 of the diaphragm 70 is easily broken by the high frequency pushing and pushing of the cylindrical balance 52, and is another problem that needs to be solved urgently.

The main object of the present invention is to provide a "damping structure and pendulum of a diaphragm booster pump" The wheel structure is improved, wherein in the diaphragm booster pump, a curved groove is recessed downwardly around the periphery of each of the actuating perforations on the top surface of the pump head, and the diaphragm is disposed at a position corresponding to each arc groove. On the bottom surface, an arc-shaped protrusion is convexly protruded downward, so that the bottom surface of the diaphragm piece and the top surface of the pump head seat are respectively adhered to each other, and each of the curved protrusions on the bottom surface of the diaphragm piece is completely embedded in the top surface of the pump head seat. In a curved groove, a short arm length is formed between the arcuate bump on the bottom surface of the diaphragm and the positioning cam, and the force of pushing the diaphragm on the bottom surface of the diaphragm is multiplied by a short The length of the arm is small, and the generated torque is reduced, which greatly reduces the vibration strength of the diaphragm booster pump.

Another object of the present invention is to provide a "damper structure of a diaphragm booster pump and a structure improvement of a balance wheel", in which three arcuate projections protruding from the bottom surface of the diaphragm in the diaphragm booster pump are embedded in the top surface of the pump head. The length of the short arm is formed in the three concave grooves of the recess, which can greatly reduce the strength of the shock absorber when the diaphragm booster pump is actuated, so that the diaphragm booster pump is equipped with a rubber cushion. The base is then fixed to the outer casing of the reverse osmosis water purifier, and does not resonate with the outer casing and makes an annoying sound.

A further object of the present invention is to provide a "damper structure of a diaphragm booster pump and a structure improvement of a balance wheel", which is to position a concave ring on a horizontal top surface of each cylindrical balance of a balance wheel of a diaphragm booster pump. 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 diaphragm booster pump rotates, the three cylindrical balance wheels are rotated by the inclined 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 piece between the positioning convex ring block and the outer convex strip in the diaphragm piece, and the concave ring groove is positioned on the horizontal top surface of each cylindrical balance wheel to The downward slope of the vertical side surface can be completely flatly supported on the bottom surface of the piston plate actuating area of the diagonally pulled state, without causing squeezing and squeezing on the bottom surface of the diaphragm piston working area, so that it can be completely Eliminate the rounding of the cylindrical balance wheel in the conventional diaphragm booster pump, and live on the diaphragm The high frequency extrusion on the bottom of the plug actuation zone is caused by the lack of easy rupture, which can greatly improve the tolerance of the diaphragm to the high frequency pushing effect of the cylindrical balance and effectively extend the service life of the entire diaphragm booster pump.

Another object of the present invention is to provide a "damper structure of a diaphragm booster pump and a structure improvement of a balance wheel", which is to position a concave ring on a horizontal top surface of each cylindrical balance of a balance wheel of a diaphragm booster pump. 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 diaphragm booster pump rotates, the three cylindrical balance wheels are rotated by the inclined eccentric cam to push up the bottom surface of the diaphragm of the piston actuation region. The upward force causes the diaphragm body between the positioning cam ring and the outer rib in the diaphragm to be in an upwardly inclined state, by positioning the concave ring groove on the horizontal top surface of each cylindrical balance to the vertical The downward slope of the side surface can be completely flatly supported on the bottom surface of the diaphragm piece in the diagonally pulled state, without causing the squeezing and squeezing of the diaphragm surface of the diaphragm piston, so that the diaphragm is subjected to the upward force. After that, the rebound force generated by the synchronization is greatly reduced, so that 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.

Figure 113 is a cross-sectional view showing a cross-sectional view of another embodiment of the cylindrical balance wheel in the eighth embodiment of the present invention and a cylindrical balance wheel in the conventional diaphragm booster pump.

As shown in FIG. 19 to FIG. 28, in the first embodiment of the present invention, the "damper structure of the diaphragm booster pump and the structure of the balance wheel is improved", which is disposed on the top surface of the pump head holder 60 near each of the actuating perforations 61. The outer periphery of the periphery is recessed with an arcuate groove 65 (as shown in FIG. 20 to FIG. 22), and an arcuate convex is protruded downward on the bottom surface of the diaphragm 70 corresponding to the position of each arcuate groove 65. Block 77 (shown in Figures 24 and 25), such that the bottom surface of the diaphragm 70 and the top surface of the pump head 60 are fitted to each other, and the three curved projections 77 on the bottom surface of the diaphragm 70 are completely embedded in the pump head. In the three arcuate grooves 65 of the top surface of the 60, a short arm length L2 is formed between the arcuate projection 77 on the bottom surface of the diaphragm 70 and the positioning collar block 76 (as shown in an enlarged view in FIG. 28). In addition, the area of the horizontal top surface 53 of each of the cylindrical balances 52 of the balance wheel housing 52 for positioning the concave ring groove 55 to the vertical side surface 56 is further provided as a downward slope 58 (as shown in FIGS. 26 and 27). Show).

As shown in FIG. 29, FIG. 30 and FIG. 15, when the diaphragm booster pump is actuated, 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 is as shown in FIG. It is smaller than the length L1 of the arm between the outer convex strip 71 and the positioning convex ring block 76 in the diaphragm 70 (as shown in FIG. 15 and FIG. 30), so the cylindrical balance 52 pushes up the bottom surface of the diaphragm 70. When the force F is multiplied by the shorter arm length L2, the generated torque is also relatively small. Therefore, the three arcuate projections 77 protruding from the bottom surface of the diaphragm 70 are embedded in the recessed top surface of the pump head holder 60. The arc-shaped groove 65 can reduce the moment effect of the cylindrical balance 52 pushing up the force F, thereby achieving the intensity of greatly reducing the shock 〞. The results measured by the prototype test show that the strength of the shock absorber of the present invention is only one tenth of that of the conventional diaphragm booster pump. If the pump body of the present invention is equipped with the conventional base 100, it is fixed in reverse osmosis.

A downward inclined surface 58 for positioning the concave ring groove 55 to the vertical side surface 56 from the horizontal top surface 53 of the cylindrical balance 52 can simultaneously completely contact and support the diaphragm actuation region 74 of the diaphragm 70 in the diagonally pulled state. On the bottom surface, 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 greatly increased. The reduction (as shown by the arrow distribution of each size rebound force Fs in FIG. 32, comparing it with the magnitude rebound force Fs in FIG. 18, it is understood that the present invention can make the diaphragm sheet 70 synchronously generate the rebound force Fs. Significantly reduced), therefore, by the horizontal top surface 53 of the cylindrical balance 52 of the present invention The downward slope 58 of the concave groove groove 55 to the vertical side surface 56 can completely eliminate the roundness 57 of the cylindrical balance 52 in the conventional diaphragm booster pump, and the bottom surface of the diaphragm 70 is activated by the high frequency of the piston 74. Excessive rupture caused by the squeezing of the sputum (as shown by the imaginary line portion in Fig. 33), and having the effect of the diaphragm member 70 being subjected to the upward force F, the synchronously generated repulsive force Fs is greatly reduced, so that the diaphragm is 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 working temperature of the motor, and thus the lubricating oil in the motor bearing will not cause high-temperature evaporation to cause lubrication.

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 three piston actuating regions 74 of the diaphragm 70. The diaphragm piece 70 and the three-piston push block 80 are simultaneously screwed into the threaded holes 514 of the cylindrical seat 511 of the three-cylinder balance 502 in the balance wheel holder 500 (as shown in an enlarged view in FIG. 110); when the output shaft of the motor 10 is output When the 11 cylinders 502 are rotated by the tilting eccentric cam 40 to push up the bottom surface of the diaphragm 70 of the piston operating region 74, the upward force F causes the diaphragm block 70 to be positioned 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. 111 and FIG. 112), 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. 112). 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 absence of the rounded corner 57 of the cylindrical balance 502 in the conventional diaphragm booster pump, which causes a defect in the bottom surface of the diaphragm 70 (shown as an imaginary line in FIG. 113), After the diaphragm 70 is subjected to the upward force F, the synchronous rebound force Fs is greatly reduced, so that the diaphragm 70 is separated. The diaphragm 70 can greatly improve the tolerance of the high-frequency pushing action of the cylindrical balance 502, thereby effectively extending the service life of the entire diaphragm booster pump, and the power is completely the same as that of the second embodiment described above. The balance ring 521 having the inwardly inclined side surface 522 and the downward inclined surface 526 must be considered in the production process, so that it can be manufactured separately from the balance wheel holder 500, thereby saving manufacturing costs. The cylindrical seat 511 can be integrally formed with the balance wheel base 500, and then combined into a cylindrical balance wheel 502. Therefore, the structural design has the dual benefits of industrial mass production and overall manufacturing cost saving.

In summary, the present invention achieves the shock absorption and efficiency of the diaphragm booster pump under the comprehensive consideration of the simplest structure without increasing the overall mass production cost, and achieves an extension by the simplest cylindrical balance wheel improved structure. The service life of the diaphragm in the diaphragm booster pump makes the service life of the entire diaphragm booster pump increase by more than twice. It is highly industrially usable and practical, and should meet the requirements of the patent. Application.
