Description

Water flow limiter

The water flow limiter of the invention is mainly applied to the technology of flow control and water saving function when the water flow pressure is too large.

According to the US certificate number: US8,714,201 "WATER-SAVING DEVICE STRUCTURE" (structure of water-saving device) invention patent case, according to the patent content, the structure of a water-saving device. When the pressure of the input water is high, the elastic stopper which is pressed downward by the water blocking piece is used to prevent the water flow from flowing from the water inflow opening of the body, so that the water flow is guided to the water passing through the water guiding hole of the water blocking piece from the body The outflow opening flows out; when the pressure of the input water is low, the water flow is conducted to the water outflow opening through the water guiding hole of the water blocking piece and the water storage circular groove portion of the circumference of the body and the water inflow opening, thereby stabilizing the outflow flow rate of the water.

However, in the above-mentioned US "WATER-SAVING DEVICE STRUCTURE" invention patent case, after the actual use for a period of time, since the water barrier piece only has a single circular hole water guiding hole, when the input water pressure is high The downwardly moving elastic stop portion is not easily rebounded back to the original position due to permanent deformation, and when the pressure of the input water is low, the water flow is affected to flow through the water storage circular groove portion and the water inflow opening to the body. The amount of outflow water and the outflow velocity of the water outflow opening cause a situation in which the amount of water is insufficient, which is a problem and a deficiency that have yet to be solved.

The present inventor is currently engaged in the manufacture and design of related products, and accumulated many years of practical experience and experience, and the existing US patent certificate number: US8,714,201 "WATER-SAVING DEVICE STRUCTURE" (structure of water-saving device) invention existing Problems and lacks, actively investing in the spirit of innovation and improvement, the completed water flow limiter.

The technical means applied to solve the problem and the effect of the prior art are as follows: the inside of the body is provided with an accommodating space for accommodating the valve body, and the accommodating space and the valve body are provided with a plurality of corresponding positioning ribs and Positioning groove, the bottom of the accommodating space is provided with two or more fan-shaped water outlet holes and ribs arranged at equal intervals, and the valve body is provided with two or more circular water outlets and supports arranged at equal intervals in the ribs. The protrusion is provided with a protrusion on the periphery of the circular water outlet hole, so that the circular water outlet hole can be suspended and erected on the rib by the protruding portion. When the water flow pressure is normal, the circular water outlet hole of the valve body is not deformed, and the water flow pressure is too large. When the circular water outlet of the valve body is bent downward and deformed into a zigzag shape corresponding to both sides of the rib, the water output of the circular water outlet is reduced, and the flow control is achieved, and the efficiency is improved. , the winner of its main purpose.
