Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and particularly relates to a limiting device for a filtered water outlet part. Background Art

[0002] A faucet is a common name for a water valve, which is used to control the size of the water flow switch and has the effect of saving water. The replacement speed of faucets is very fast. It has developed from the old cast iron process to the electroplated knob type, and then to the stainless steel single-temperature single-control faucet, the stainless steel double-temperature double-control faucet, and the kitchen semi-automatic faucet. Now, more and more consumers will comprehensively consider various aspects such as material, function, and shape when purchasing a faucet.

[0003] There is only one water outlet hole at the water outlet end of the traditional faucet for water outlet. When customers need to use tap water and purified water, two faucets need to be installed on the countertop, and the two faucets are respectively connected to the tap water and purified water inlet pipes.

[0004] A new type of filtered water outlet part with the Chinese patent application number 2024213031187 includes a shell, a valve seat arranged at one end of the shell, a valve core body arranged in the valve seat, a water storage cavity opened on the shell, a first water inlet hole opened on the valve seat and communicated with the water storage cavity, a first water outlet hole opened at the lower end of the shell and communicated with the water storage cavity, a filtering device arranged in the water outlet cavity on the shell and communicated with the first water outlet hole for filtering impurities in the water flow when the water flow enters the water storage cavity and allowing the filtered water flow to flow out from the first water outlet hole, a water outlet seat arranged at the other end of the shell, a second water inlet hole opened on the valve seat, and a second water outlet hole opened on the water outlet seat and communicated with the second water inlet hole. The valve core body includes a pipe body, a water inlet opening opened at one end of the pipe body for allowing external water flow to flow into the pipe body, a water outlet opened at the other end of the pipe body and communicated with the water inlet opening for allowing the water flow flowing into the pipe body to flow outwards, a connecting device arranged at one end of the pipe body for fixedly connecting with an external water inlet pipe, an installation device arranged at the other end of the pipe body for connecting with the valve seat, the water outlet is eccentrically arranged on the other end face of the pipe body, the first water inlet hole and the second water inlet hole are eccentrically arranged on the valve seat, and a matching hole for cooperating with the installation device is opened on the valve seat, and the matching hole is arranged at the central end of the valve seat.

[0005] In the above patent application, the switching of the water outlet modes of tap water and purified water can be realized under the condition of installing one faucet, and the use functions are diverse. However, when the water flow accumulates in the water storage cavity, it is easy to increase the weight of the shell, and the valve seat and the valve core body are in a rotatable state. Therefore, when the water flow gradually accumulates in the water storage cavity, the shell is easy to drive the valve seat to rotate on the valve core body, which is likely to affect the normal use of the water outlet part.
