Description

Technical Field

[0001] The utility model belongs to the technical field of shower equipment, and in particular relates to an anti-clogging shower head structure. Background Art

[0002] Shower head, also known as shower head, is a structural component used to disperse the coarse water flow in the water outlet pipe into fine water flow and spray it out. Conventional top spray shower heads are generally set horizontally and a connecting joint is set at the center of the top to connect with the water outlet pipe. The top spray shower head with this structure has fine water outlet holes evenly opened on the lower shell of the shower body, the central axis of the water outlet holes is in the vertical direction, and the upper end of the water outlet holes is flush with the top surface of the lower shell of the shower body. When the top spray shower head with this structure is in use, the water entering the shower body from the water outlet pipe is directly sprayed out from top to bottom through the water outlet holes. In this process, the impurities (especially the particulate impurities with large specific gravity, colloids, etc.) carried by the water entering the shower body will directly deposit downward on the top surface of the lower shell or directly block the upper end of the water outlet hole. In the past, not only was there a lot of dirt accumulated in the shower head, bacteria and viruses were breeding, but also the blockage of the water outlet holes also affected the normal use of the top spray shower head.
