[embodiment]
As shown in Figure 15 to Figure 22, the first embodiment for the vibration control structure of the utility model diaphragm booster pump, it is that the periphery around each start perforation 61 is arranged with an arc groove 65 downwards on pump head seat 60 end faces, and on diaphragm 70 bottom surfaces of corresponding these each arc groove 65 positions, be convexly equipped with an arc bump 76 downwards, after making the bottom surface of diaphragm 70 and the end face of pump head seat 60 bonded to each other, three arc bumps 76 of these diaphragm 70 bottom surfaces embed three arc grooves 65 interior (as shown in the zoomed-in view in Figure 22) of pump head seat 60 end faces completely
Continuous as Figure 23, shown in Figure 24 and Figure 13, when diaphragm booster pump start, due to the arc bump 76 of diaphragm 70 bottom surfaces and the arm of force length L 2(between positioning convex ring 75 as shown in figure 24), be less than in diaphragm booster pump the arm of force length L 1(between seal groove raised line 71 and positioning convex ring 75 as shown in Figure 13 and Figure 24), therefore the escapement 52 up directed force F of pushing tow diaphragm 70 bottom surfaces is multiplied by shorter arm of force length L 2, the moment producing also diminishes relatively, therefore, three arc bumps 76 that are convexly equipped with by diaphragm 70 bottom surfaces embed three arc grooves 65 that pump head seat 60 end faces are arranged with, can reduce the upwards moment loading of thrusting action power F of escapement 52, and then reach the intensity that significantly reduces 〝 vibrations 〞, via the result after pilot sample actual measurement, show, 〝 vibrations 〞 intensity of the present invention only has 1/10th of known diaphragm booster pump, if the pump housing of the present invention is installed after known base 100, it is fixed on the shell C upper (as shown in figure 14) of anti-penetration water purifier, can not empathize completely and send the irritating sound.
Wherein, the variable arc perforation (not shown) that is set as of this arc groove 65 in above-mentioned the utility model the first embodiment; In addition, this arc groove 65 also can be transformed into the chimeric mode of arc bump and arc groove mutually with corresponding arc bump 76.
As shown in Figure 25 to Figure 31, the second embodiment for the vibration control structure of the utility model diaphragm booster pump, wherein, on these pump head seat 60 end faces around the bore a hole arc groove 65 of 61 peripheries of start, more in its periphery, set up one the second arc groove 66(as shown in Figure 25 to Figure 27), and on diaphragm 70 bottom surfaces of corresponding these the second arc groove 66 positions, also in arc bump 76 peripheries, set up one the second arc bump 77(downwards as shown in Figure 29 and Figure 30), after making the bottom surface of diaphragm 70 and the end face of pump head seat 60 bonded to each other, this arc groove 65 and the second arc groove 66 embed respectively in arc bump 76 and the second arc bump 77 (as shown in Figure 31 and zoomed-in view thereof) completely, except having the effect that significantly reduces 〝 vibrations 〞 originally, more can increase while resisting escapement 52 thrusting action power F not by the steadiness of displacement.
Wherein, the equal variable arc perforation (not shown) that is set as of this arc groove 65 and the second arc groove 66 in above-mentioned the utility model the second embodiment; In addition, this arc groove 65 and the second arc groove 66 arc bump 76 and the second arc bump 77 corresponding thereto, also can be transformed into the chimeric mode of arc bump and arc groove mutually.
As shown in Figure 32 to Figure 38, the 3rd embodiment for the vibration control structure of the utility model diaphragm booster pump, it is that the periphery around each start perforation 61 is arranged with a whole circle concave ring groove 601(downwards as shown in Figure 32 and Figure 34 on pump head seat 60 end faces), and be convexly equipped with a whole circle bulge loop piece 701(downwards as shown in Figure 36 and Figure 37 on the bottom surface of the diaphragm 70 of corresponding these whole circle concave ring groove 601 positions), after making the bottom surface of this diaphragm 70 and the end face of pump head seat 60 bonded to each other, the whole circle bulge loop piece 701 of these diaphragm 70 bottom surfaces embeds the whole circle concave ring groove 601 interior (as shown in figure 38) of pump head seat 60 end faces completely, chimeric spacing by whole circle concave ring groove 601 and whole circle bulge loop piece 701, have more the effect of 〝 damping 〞.
Wherein, in above-mentioned the utility model the 3rd embodiment, this whole circle concave ring groove 601 is variable is set as whole circle scrobicular ring perforation (not shown); In addition, this whole circle concave ring groove 601 whole circle bulge loop piece 701 corresponding thereto, also can be transformed into the chimeric mode of whole circle bulge loop piece and whole circle concave ring groove mutually.
