Vibration reduction structure of four-booster-cavity membrane pump

Abstract

The invention relates to a vibration reduction structure of a four-booster-cavity membrane pump. An arc-shaped groove is downwards formed in the top face of a pump head base of the four-booster-cavity membrane pump around the periphery of each actuation penetrating hole in a concave manner, an arc-shaped convex block is downwards arranged at the position, corresponding to each arc-shaped groove, of the bottom face of a membrane sheet in a convex manner, so that after the bottom face of the membrane sheet is attached to the top face of the pump head base, each arc-shaped convex block on the bottom face of the membrane sheet is fully embedded in the corresponding arc-shaped groove in the top face of the pump head base; and small force arm length is formed between each arc-shaped convex block on the bottom face of the membrane sheet and one corresponding locating convex ring, so that after acting force of balance wheels jacking the bottom face of the membrane sheet upwards is multiplied by the small force arm length, generated torque becomes small, and therefore the vibration strength of the four-booster-cavity membrane pump in the actuation process is greatly lowered.

Description

technical field [0001] The present invention is related to a diaphragm booster pump installed in a reverse osmosis water filter (reverseosmosispurification), or used in a bathroom kitchen water supply equipment in a recreational vehicle (recreationalvehicle), in particular to a pump that can greatly reduce the vibration intensity when the pump body is in motion. The structure makes it installed on the casing of the reverse osmosis water filter or the bathroom and kitchen water supply equipment in the caravan, so that the casing will not resonate 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 d...

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
