Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, and in particular to a water outlet and a water outlet installation method. Background Art

[0002] Traditional faucet spouts mostly adopt a simple through-hole structure, which discharges columnar water. In order to meet different water needs, the faucet spouts are equipped with various water heads, the most common of which is the bubble water head. At present, most of the water heads on the market are assembled into one piece and then installed into the faucet outlet through threads. Although this installation method is simple, there is a problem of poor alignment after installation, especially for water heads with a rotating flow adjustment function. When the position of the maximum gear or the minimum gear cannot face the user or a preset position after installation, there will be problems such as inaccurate indication and inadequate adjustment during gear adjustment, which brings a bad user experience to consumers. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a water outlet installation structure with more correct markings after installation.

[0004] In a first aspect, a water outlet head is provided, comprising an assembly seat, a switching assembly, a valve seat, a switch seat, a nut and a water outlet module, wherein: The assembly seat is pre-fixed at the water outlet of the faucet and is provided with an installation cavity.

Specifically, the switch seat sleeve is arranged on the outside of the valve stem and docks with the valve seat. A limiting structure for limiting the rotation flexibility is provided between the switch seat and the valve stem, so that when the switch seat is rotated by the user, the valve stem also rotates, and the switching assembly enters any gear position through the rotation of the switch seat. The nut is locked at the end of the valve stem, and together with the valve stem, the switch seat and the valve seat are clamped to prevent water leakage between the switch seat and the valve seat.

[0005] The water outlet module is installed at the water outlet end of the switch seat.

[0006] The present invention provides a water outlet, wherein the assembly seat is pre-arranged together with the water outlet of the faucet, so as to solve the problems that when the installation position of the water outlet is directly set on the existing faucet, it is difficult to form and the precision after forming is poor and the installation error is large, so that the subsequent valve seat and the switch seat can be installed in the water outlet of the faucet in a desired state or angle, avoiding the problem of inadequate adjustment of the water outlet state caused by the installation error.

[0007] Preferably, a mark is provided on the outer periphery of the switch seat for the user to check the current water outlet status. When in use, the mark rotates to a preset position when the switching assembly enters a preset gear, and then the mark related to the water outlet status can be installed at the preset position by setting a limiting structure. Thus, the mark can provide the user with accurate water outlet status information, avoid misoperation, provide convenience for use, and at the same time, make the product more textured.

[0008] Preferably, the preset position is the position directly in front of the user after the water outlet is installed, which is convenient for the user to observe, and the preset gear position is the maximum water volume gear position or the minimum water volume gear position.

A special-shaped groove is provided in the middle of the movable valve plate, and a special-shaped head is provided at the end of the valve stem and inserted into the special-shaped groove of the movable valve plate.

[0012] Preferably, in order to simplify the water channel structure and improve the integrity of the water channel, the valve stem is provided with a water passage, and the water passage is connected to the water hole of the fixed valve plate, thereby preventing the water channel from being too fragmented and prone to water leakage.

[0013] Preferably, the hole in the valve seat for the valve stem to pass through is a stepped hole, and the valve stem is stepped, so that the valve seat and the nut can clamp the valve seat and the switch seat.

[0014] Preferably, the hole of the switch seat for the valve stem to pass through is provided with a flat surface, and the periphery of the valve stem is also provided with a flat surface. The flat surfaces between the switch seat and the valve stem are aligned and fitted to form the limiting structure, which has a simple structure and is easy to form.
