Description

{One-hole head for kitchen with double binding structure}

The present invention relates to a kitchen one-hole head having a double binding structure. More specifically, the filter assembly cover and head body assembled with the discharge pipe of the kitchen one-hole faucet are configured to be opened and closed more easily, making it easy to replace the filter member. , It was invented to improve ease of assembly and ease of use.

Generally, a kitchen one-hole faucet is installed in the center or on one side of the kitchen sink, and is either integrally formed in the shape of a " It is configured to discharge cold water selectively or mixed.

Here, the one-hole head combines a front cap with a spray plate with a plurality of spray holes drilled on the lower outlet side, so that tap water supplied through the discharge pipe moves along the flow path in the head and is sprayed into the spray holes. .

In addition, since the chlorine component used in the process of disinfecting water in water treatment facilities is not easily removed and remains dissolved in the water, the tap water generates a unique chlorine odor.

Recently, as a way to solve the problem of worsening skin diseases of users due to the chlorine contained in tap water and residues such as rust due to corrosion inside the water pipes, a filter member was installed inside the one-hole head. The provided product is also proposed and configured to remove and filter foreign substances, chlorine components, and residues contained in tap water supplied through the discharge pipe and then spray it.

However, the filter member provided inside the one-hole head is small in size, making it difficult to remove and filter chlorine, residues, and rust in tap water. In order to replace the contaminated filter member, it must be connected to the head body. The filter assembly cover must be separated and refastened, but as the fastening tip of the filter assembly cover hardens due to hot tap water and aging, etc., cracks are easily formed in the process of fastening to the head body, causing water leakage.

That is, the one-hole head and the filter assembly cover are each formed with threaded parts corresponding to each other, and the user holds the filter assembly cover assembled on the discharge pipe and then rotates the head body to fasten or separate it.

However, the head body and the filter assembly cover are generally injection molded from synthetic resin materials, so if the threads of the filter assembly cover and the head body are rotated in a misassembled state, the threads are broken and damaged, forming the damaged gap. Water leakage occurred, and if the fastening part was tightened too much, cracks were easily formed at the threaded end of the filter assembly cover, causing inconvenient problems such as having to repurchase and use the entire head body and filter assembly cover or replacing only the filter assembly cover. .
