Shock-absorbing structure of four-pressure chamber diaphragm pump

Abstract

The present invention relates to a shock absorbing structure of a diaphragm pump with four pressurization chambers. On the top surface of the pump head seat in the diaphragm pump with four pressurization chambers, an arc-shaped groove is recessed downward around the periphery of each actuation perforation. And on the bottom surface of the diaphragm corresponding to the position of each arc-shaped groove, an arc-shaped protrusion is protruded downward, so that after the bottom surface of the diaphragm and the top surface of the pump head seat are attached to each other, each part of the bottom surface of the diaphragm will An arc-shaped protrusion is completely embedded in each arc-shaped groove on the top surface of the pump head seat, and a short arm length is formed between each arc-shaped protrusion on the bottom surface of the diaphragm and each positioning protrusion ring, so that After the force of the balance wheel pushing up the bottom surface of the diaphragm is multiplied by the short arm length, the generated moment becomes smaller, thereby greatly reducing the "vibration" intensity when the four-chamber diaphragm pump operates.

Description

technical field [0001] The present invention is related to a diaphragm booster pump installed in a reverse osmosis purification, or a water supply equipment for bathroom and kitchen in a recreational vehicle. The vibration strength structure makes it installed on the casing of the reverse osmosis water filter or the bathroom and kitchen water supply equipment in the caravan, and it will not resonate the casing and cause annoying sounds. Background technique [0002] Currently used in the reverse osmosis water filter and the dedicated four-boost chamber diaphragm pump for the bathroom and kitchen water supply equipment in the traveling caravan, except that it has been disclosed such as US Patent No. 6840745, another kind is similar to the US Patent No. 6840745 and has been recognized. The structure of the conventional four booster chamber diaphragm pump adopted in large quantities is as follows: Figure 1 to Figure 9 Shown, by a motor 10, a motor front cover 30, an inclined e...

Problems solved by technology

[0005] Therefore, if Figure 14 As shown, a conventional diaphragm pump with four pressurization chambers is equipped with a base 100 on the outer edge of the pump body, and a pair of rubber shock absorbing pads 102 are respectively set on the two side flanges 101 of the base 100, and then fixed screws 103 and screws The cap 104 fixes the base 100 to the reverse osmosis water filter, or the shell C of the bathroom and kitchen water supply equipment in the caravan; however, in fact, two pairs of rubber shock absorbers 102 on the two side wings 101 of the base 100 are used to achieve damping. The effect of shock is quite limited, because the "vibration" intensity produced by the action of the pump body is extremely large, it will still cause the resonance of the shell C and send annoying sounds. In addition, the water pipe P connected to the pump head cover 20 water outlet 22 is also It will vibrate synchronously with the frequency of "vibration" (such as Figure 14 As shown by the imaginary line P in the view a) and hit 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 joint will gradually become loose due to shaking The phenomenon will eventually lead to the result of water leakage. Many of the above defects are caused by the "vibration" generated by the operation of the four-chamber diaphragm pump, so how can the "vibration" generated by the operation of the four-chamber diaphragm pump be greatly reduced "The lack of it has become a very urgent issue to be solved
