The middle drain seat 41 is positioned and fits snugly to the position of the three regions 43. The three piston pieces 8〇 are also 7 inverted ^ 4 soft < elastic material - body formed down! The umbrella body, #top central convex a^, the positioning post 81 are respectively inserted and embedded in the foot hole 45 of each water inlet seat 44, and can block all the water inlet holes 46 of each water inlet seat 44. 'And the space between each piston piece 80 and its corresponding piston-pushing block 3' will form three low-pressure water chambers 3 in the three water inlets 44, and each of the low-pressure waters The other end of the chamber 3 is connected to the drain hole 43 at each position in the drain seat 41 (as shown in the fourth, fifth and sixth figures). In addition, the pump head cover 50 is a hollow body having an opening at the bottom, and an opposite water inlet 52 and a water outlet 53 are disposed on the top outer edge surface, and a plurality of perforations 5 are provided on the peripheral surface of the bottom portion.丨 (as shown in the first and third figures), a stepped groove 54' is recessed on the inner edge surface of the bottom opening, and a circular groove 55 is protruded from the center of the inner edge surface toward the bottom opening direction. After the bottom end surface of the annular groove 55 is pressed against the outer peripheral surface of the drain seat 41 of the piston valve body 40, the inner wall surface of the annular groove 55 and the top surface of the drain seat 41 of the piston valve body 40 can be made. The space is directly surrounded by a high pressure water chamber 4 201013049 (as shown in the fourth and fifth figures), wherein the horizontal bottom surface 542 of the lower step groove 541 of the step groove 54 and the space formed by the upright wall surface 543 are surrounded. The top surface 61 of the water stop gasket 6 抵 is placed in contact with the outer side surface 63, and the space formed by the horizontal bottom surface 545 of the upper step groove 544 and the upright wall surface 546 is just enough for the outer rib 22 of the diaphragm piece. The top surface 221 is in abutment with the outer side surface 222 (as shown in a partial enlarged view of the stepped groove 54 in the second figure) For the continuation, please refer to the fourth to sixth figures. It is the operation mode of the above-mentioned conventional diaphragm pump. When the motor 1G is started, the tap water w will enter the water inlet 52 of the chestnut cover body 5G, and the piston valve body will be inserted. The piston plate 80 on the fourth turn is pushed open and enters the low pressure water chamber 3 via the water inlet hole 46 in the water seat 44 via the piston valve body 40 (as indicated by the arrows in the fourth and fifth figures). The output shaft of the motor 1〇 sequentially drives the respective swings 13 to actuate. [The piston push blocks 3 () will synchronously cause the piston actuating regions 24 on the diaphragm 2G to vibrate up and down. Thus, the low pressure water chamber is squeezed. The tap water w in 3, and the water pressure is increased to between 80 pSi and 100 psi, so that the boosted high-pressure water Wp can push the anti-reverse capsule 70 of the piston valve body 4 〇 drain seat 4i i away Each drain hole 43 of the drain seat 41 continuously flows into the high M water chamber 4, and finally exits the diaphragm through the water outlet 53 (as indicated by the arrow in the sixth figure) to provide reverse osmosis 2010 9 201013049 water The RO membrane tube is used for the water pressure required for reverse osmosis filtration. Again, the fourth, sixth, and tenth As shown in the figure, during the operation of the conventional diaphragm pump, when the motor 10 rotates to cause the three balance wheels 13 to move axially in sequence, the three pistons of the diaphragm 20 of each balance wheel 13 must be screwed. The actuating zone 24' synchronously generates an axial forward and backward thrusting action (as shown in the sixth figure) and causes the edge top surface 403 of the base body 401 of the piston valve body 40 to generate a vertical force Fv, which continually collides The bottom surface 62 of the water washer 60 is pressed (as shown in FIG. 7), so that the top surface 61 and the bottom surface 62 of the water stop gasket 6 are continuously received between the edge top surface 403 and the lower step groove 541. The pressing force phenomenon between the middle horizontal bottom surface 542 (as shown in the eighth figure), as long as the motor 1 turns one turn, the three balance wheels 13 are pushed in the axial direction - a total of 3 times 'If the motor's speed is 1 rpm (700 RPM), it means that 7 〇〇χ 3 = 2100 times of vertical force Fv per minute will impact the water stop washer 60'. 6〇The original between the top surface 61 and the bottom surface 62 after being subjected to such a high frequency of constant back and forth collision The thickness H' will gradually be reduced by compression to become a thinner thickness ^ (as shown in the seventh and eighth figures), where the thickness of the deformation between the original thickness H and the thinner thickness h is The gap between the green top surface 4〇3 of the base 401 of the piston valve body 40 and the water stop washer (6) 201013049, the bottom surface 62 (shown in FIG. 9), or the lower step of the stepped groove 54 of the pump head cover 50 A gap G between the horizontal bottom surface 542 of the groove 541 and the top surface 61 of the water stop washer 60 (as shown in the tenth diagram). Furthermore, since both the diaphragm piece 20 and the pump head cover 5 are not made of a rubber-like soft material, but are made of a plastic material having a rigid strength, the two are not completely adhered to each other, and are mutually After a period of operation, a gap δ (as shown in the ninth and tenth views) is always generated between the outer rib 22 of the diaphragm and the upright wall 546 of the upper slot 544 of the stepped groove 54. In addition, when all the conventional diaphragm pumps are installed in the reverse osmosis water filter system, the water inlet 52 of the pump head cover 50 is connected to the water pipe by a pipe joint J (as shown in the fourth figure). The imaginary line in the middle), regardless of the users living in the building or the single-family building, the water storage tower in the house is the most widely installed in the building. Therefore, there is a considerable distance between the water storage tower and the diaphragm pump. Height difference 'When the motor 10 starts to pressurize each time, the tap water w flowing out of the water pipe of the water storage tower will be accompanied by the instantaneous water hammer force Wg' if it is caused by the potential energy and the gravity phenomenon. When the gap G formed by the thickness reduction of the water stop ring 6 , and the gap δ between the outer rib 22 and the upright wall surface 546 of the upper groove 201013049 544 in the step groove 54 are encountered, The tap water w accompanying the water hammer pressure Wg will leak into the top surface 403 of the piston valve body 4 401 base and the bottom surface 62 of the water stop washer 6 immediately after entering the water inlet 52 of the pump head cover 50.

The level of the top surface 61 and the groove 56 is caused by the thickness of the water stop gasket 6 after being hit for a period of time. There will still be a gap G between the bottom surface 561 (as shown in Figure 13), so there is water The tap water w of the pressure Wg will also leak into the gap 立即 immediately after entering the water inlet 52 of the pump head cover (as shown in Fig. 12), and finally through the outer side 224 of the outer rib 22a and the concave The gap δ between the upright wall surfaces 562 of the groove 56 leaks directly from the outside of the diaphragm pump between the pump head cover 50 and the upper cover seat 11. Therefore, the above-mentioned 'leakage of leakage water' does not occur immediately after the new product is used. However, if the area where the user lives is in the tropical zone or the 201013049 cold zone, its effect on climate thermal expansion is more significant. The aging of the material of the water-stopping item 60 will be intensified, so that it often does not reach the warranty period of the diaphragm pump, so that all manufacturers that produce the diaphragm gather have to be forced to replace the new product: Your long-term 'not long-term damage not only causes damage to the reputation of its own products. 》 'It will increase the overall manufacturing and maintenance, so how to solve this problem effectively and simply, the leakage is missing," become an important thing to be relieved Question. SUMMARY OF THE INVENTION After deep understanding and painstaking research, the present inventors finally obtained a breakthrough and effective solution to the aforementioned "missing of leakage phenomenon", and the main object of the present invention is to provide a "diaphragm pump head cover". The leakage stop structure of the body is formed by arranging the upright wall surface of the lower step groove in the stepped groove at the bottom of the pump head cover body so that the water stop washer is positioned on the top surface of the piston valve body base. Then, when the plug is placed in the stepped groove of the pump head cover, the outer side surface of the water stop washer is pressed by the contact of the inclined wall surface in the lower step groove, and immediately on the outer side surface of the water stop washer Producing a horizontal force 'receives the outer edge of the positioning rib of the piston valve body to resist the 'sudden deformation of the water stop gasket' and causes the corresponding direction to be generated in the interior The external vertical inward stress, and thus the vertical inward stress continues to act, so that the 14 201013049 water stop gasket can be tighter with the step groove of the pump head cover and the base of the piston valve body. Stop state and has a high pressure water nozzle diaphragm outer leaking out effect. Another object of the present invention is to provide a "leakage prevention structure for a diaphragm head of a diaphragm pump" which is provided with a sloping wall surface at a intersection of a horizontal bottom surface and an upright wall surface in a groove in the bottom opening of the pump head cover body. When the diaphragm piece is overlapped with the piston valve body, and the water stop ring sleeve is positioned on the top surface of the edge of the piston valve body base, and then the groove is placed tightly into the groove of the pump head cover body, the diaphragm piece The top end surface of the middle and outer ridges is immediately restrained by the inclined wall surface in the groove, and is inclined and contacted to the outer side surface of the water stop gasket, and immediately produces a horizontal direction on the outer side surface of the water stop washer The force' is then blocked by the outer edge of the positioning rib in the piston valve body, which causes the water stop washer to produce a vertical squeezing deformation and will internally generate a corresponding outward vertical inward direction. The force, therefore, under the continuous action of the vertical inward stress, the water stop gasket can be respectively formed with the step groove of the pump head cover body and the base of the piston valve body to achieve a tighter state and has a high pressure water leakage resistance. Membrane pump external effect. [Embodiment] As shown in the fourteenth to sixteenth drawings, the first embodiment of the "leakage prevention structure of the diaphragm head of the diaphragm pump" of the present invention is the opening of the bottom of the head cover 50 of the pump ginseng 201013049. In the stepped groove 54, the upright wall surface of the lower step groove 54i is provided with an inclined wall surface 547 (as shown in a partial enlarged view in the twelfth figure) so that the water stop gasket .6 is positioned in the piston valve body 40 in the sleeve. After the edge top surface 4〇3 of the base 401 is placed and then placed in the stepped groove 54 of the pump head cover 50 (as shown in FIG. 15), the outer side surface 63 of the water stop washer 60 is stepped. The contact 54 in the groove 54 is pressed by the contact of the inclined wall surface 547 in the lower step groove 541, and the water force is immediately generated on the outer side surface 63 of the water stop washer 60 as indicated by the solid arrow in the sixteenth figure) = the rim of the outer edge of the positioning rib 47 in the piston valve body 40 will cause the water stop gasket 6 〇 to produce a vertical deformation deformation, and the corresponding generation direction will be synchronized therein. External vertical inward stress F (as indicated by the semi-solid arrow in Figure 16), and thus in the vertical direction Under the action of the stress F, the water stop ring 6 〇 can be respectively formed with the step groove 54 of the chestnut cover body 50 and the base of the piston body 4 , to achieve a tighter state and has a high pressure water WP leakage. The effect of the outside of the diaphragm pump. Further, as shown in Figs. 17 to 19, the second embodiment of the "leakage prevention structure of the pump head cover" of the present invention is a groove 7 57 and a straight opening at the bottom of the pump head cover 50. Now, the intersection of the horizontal bottom wall 572 is provided with an inclined wall surface 201013049 573, and one end of the inclined wall surface 573 is in contact with the horizontal bottom surface 571 and the other end is in contact with the vertical wall surface 572; When the diaphragm piece 20 and the piston valve body 4 are stacked, the water stopping washer (9) is sleeved on the edge top surface 4〇3 of the piston valve body 4〇4〇1, and then placed tightly. After the groove 57 of the pump head cover 5〇 (as shown in FIG. 18), the end top surface 223 of the diaphragm rib 2 is immediately restricted by the inclined wall surface 573 of the groove 57. Tilting and contacting the outer side surface 63 that is pressed against the water stop gasket 6〇, and immediately produces a horizontal force Fh on the outer side surface of the water stop washer 6〇 (as indicated by the solid arrow in the nineteenth figure) At this time, the outer edge side 48 of the positioning rib 47 in the piston valve body 4 阻 is blocked, so that the Water produced extruded gasket ⑽ perpendicular to deformation, and will generate corresponding vertical synchronization inwardly stress F (such as semi-solid arrow heads shown in FIG nineteenth) outwardly in its interior, and thus inwardly of the vertical stress? Under the continuous action, the water stop gasket 6 can be brought into a tighter state with the groove 57 of the pump head cover 50 and the base 4〇1 of the piston valve body 4, respectively, as in the first embodiment. And has the effect of blocking the high-temperature water Wp from leaking out of the diaphragm pump. In summary, the invention has been proved by the inventors to prove that the leakage of the entire pump head cover in the diaphragm pump is lacking.
