Spray head assembly

Technical Field

The invention belongs to the field of bathroom accessories, and particularly relates to a spray head assembly.

Background

The nozzle is also called as a shower head, a shower head and the like, and is originally a device for watering flowers, potted plants and other plants. Later, people modified the shower device to become a common bathroom product, a shower head and a bathroom widely used in daily family toilets.

When the shower head is used as a shower head, the shower head is a cleaning tool widely used for bathing, and a hand-held shower head which is held in a hand to shower is more commonly used. A conventional shower head includes a handle portion and a head portion connected together, a lower end of the handle portion being connected to a water inlet pipe, and when a faucet is opened, water flows into the head from the water inlet pipe and is sprayed from the head portion to perform a shower.

When the busy work of a day is finished, people can relax when taking a shower and bathing. When people have a bath, people often use the shower nozzle to wet the body or the hair, and then put down the shower nozzle to squeeze the shower gel or the shampoo, so that the shower gel or the shampoo is inconvenient, and the shower gel and the shampoo are iced in winter, so that people feel uncomfortable. At present, some improved shower nozzles are combined with shampoo or shower gel, mixed liquid can come out when water flows out, and the shower nozzle is convenient to use.

Further research is carried out to the shower nozzle subassembly among the prior art to this application, makes its use more convenient.
