Description

Technical Field

[0001] The utility model belongs to the technical field of shower heads, and particularly relates to a shower head. Background Art

[0002] Shower heads, also known as showerheads, were originally a device for watering flowers, potted plants and other plants. Later, some people modified it into a shower device, making it a common item in the bathroom.

[0003] Most of the shower heads on the market are directly connected to the faucet. When in use, the clean water is dispersed through the shower head so that the clean water is sprayed on the user's body more evenly. In order to facilitate the use of the user, there are also some shower heads on the market that can assist in spraying shampoo or shower gel, and can even produce foam with water mixed with shampoo or shower gel, such as Chinese invention patent application CN202311800402.5 A foaming bathing machine is disclosed, which comprises a foaming device. The foaming bathing machine also comprises a bath liquid feeding device and a water supply device. The bath liquid feeding device and the water supply device are two separate and independent feeding systems, which respectively feed materials into a bubbler. The foaming bathing machine comprises a water inlet, a water outlet, a water supply device, a bath liquid feeding device and a foaming device. The foaming device comprises a bubbler. The bubbler is provided with a water inlet, a bath liquid input port and a bubble outlet. The water supply device comprises a main water supply pipeline and a branch pipeline. The main water supply pipeline is responsible for the water inlet and water outlet of the foaming bathing machine. The branch pipeline is divided from the main water supply pipeline, and water flows into the bubbler through the water inlet. The bath liquid feeding device flows the bath liquid into the bubbler through the bath liquid input port. The bubbler mixes water and bath liquid to form foams and flows out to the water outlet of the main water supply pipeline for output.

[0004] The above-mentioned foaming bath machine can realize long-term and long-pipe foam supply, and the foam supply quality is stable, and it can also realize mutual switching between water output and foam output, which is convenient to use. However, since the bubbler mixes water and bath gel to foam and flows out to the water outlet end of the main water supply pipeline for output, the water in the main water supply pipeline will dilute the bath gel during bathing, so that the content of bath gel is low, which affects the generation of foam, and when the user needs to flush, the liquid mixed with bath gel in the shower head and the pipeline needs to be discharged first, which leads to waste of water resources.

The arrangement of multiple groups of liquid storage chambers 41 and shunt pipes 214 is convenient for users to place bath liquids such as shampoo and shower gel separately. Different shunt pipes 214 are connected with the water inlet end 23 through the control of the control valve 6, which is convenient for users to use different bath liquids. Preferably, the guide pipe 43 is made of a corrugated pipe.

[0056] The control valve 6 described in the utility model includes a control knob 61, and the control knob 61 has at least two sets of gears.
