Shock Absorbing Structure and Balance Wheel Structure of Diaphragm Booster Pump

Abstract

The invention relates to an improved shock absorbing structure and a balance wheel structure of a diaphragm booster pump. An arc-shaped groove is recessed downward around the periphery of each actuation perforation on the top surface of the pump head seat in the diaphragm booster pump. , 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 a short arm length is formed between the arc-shaped protrusion on the bottom surface of the diaphragm and the positioning protrusion ring , and the torque generated by the pump body becomes smaller when the pump body is in motion, thereby greatly reducing the intensity of "vibration". In addition, the concave ring groove is positioned on the horizontal top surface of each cylindrical balance wheel of the balance wheel seat to the vertical side surface The area of ​​the diaphragm is set as a downward slope, so that when the diaphragm booster pump operates, there will be no "squeeze" on the bottom surface of the diaphragm.

Description

technical field [0001] The present invention is related to a diaphragm booster pump installed in a reverse osmosis purification, in particular to a structure that can greatly reduce the vibration intensity of the pump body when it is actuated, so that it can be installed in a reverse osmosis water filter After the casing is installed, it will not resonate the casing and cause annoying noises, and the cylindrical balance wheel structure of the balance wheel seat is improved, so that the pump body will not squeeze the bottom surface of the diaphragm when it is in motion " is missing. Background technique [0002] Currently known membrane booster pumps used in reverse osmosis water filters have been disclosed such as U.S. Patent Nos. 4,396,357, 4,610,605, 5,476,367, 5,571,000, 5,615,597, 5,649,812, 5,706,715, 5,791,882, and 5,816,133. Figure 1 to Figure 11 Shown, be by a motor 10, a motor front cover 30, an inclined eccentric cam 40, a balance wheel seat 50, a pump head seat 6...

Problems solved by technology

[0005] Therefore, conventional diaphragm booster pumps are all equipped with a base 100 (such as Figure 16 As shown), a pair of rubber damping pads 102 are respectively set on the two side wings 101 of the base 100, and then the base 100 is fixed on the shell C of the reverse osmosis water filter with fixing screws 103 and nuts 104; however, in practice Using the two pairs of rubber damping pads 102 on the wings 101 on both sides of the base 100 to achieve shock absorption is quite limited, because the "vibration" generated by the action of the pump body is extremely strong, and it will still cause the shell C to resonate and emit An annoying sound. In addition, the water pipe P connected to the pump head cover 20 water outlet 22 will also shake synchronously with the frequency of "vibration" (such as Figure 16 (shown by the imaginary line P in ) and slaps 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, and finally It will lead to water leakage. Many of the aforementioned defects are caused by the "vibration" generated by the operation of the diaphragm booster pump. Therefore, how to greatly reduce the "vibration" defect caused by the operation of the diaphragm booster pump has indeed become quite urgent. Issues to be solved
