Self-cleaning shower head

Abstract

The invention provides a self-cleaning shower head. The shower head includes a shower head body, a descaling needle plate and a surface cover assembly; the surface cover assembly includes a water outlet surface cover and a backboard; the water outlet surface cover and the backboard are in mutual splicing, and an accommodating chamber can be formed between the water outlet surface cover and the backboard; the descaling needle plate is fixedly arranged in the accommodating chamber; the backboard is provided with an opening which can connect a water inlet channel and the accommodating chamber inthe axle center, and a flow passing channel can be formed between the inner wall of the opening and a fixing mechanism arranged in the shower head body; the end face of the opening can make the surface cover assembly integrally move downward relative to the descaling needle plate by the impact force of water flow, the distance between the inner wall of the opening and the fixing mechanism in the shower head body can be increased during the down moving of the surface cover assembly, and the cross-sectional area of the flow passing channel can be enlarged; and the parts in the accommodating chamber except for the opening and the water outlet nozzles of the water outlet surface cover are maintained to be sealed.

Description

technical field [0001] The invention relates to a shower head, in particular to a descaling shower head. Background technique [0002] The shower head is a kind of shower equipment that is widely used in daily life. When the shower head is used for a long time or in a place with poor water quality, scale is easy to adhere to the wall of the water outlet hole on the water outlet cover, and the scale will accumulate over time. The water outlet hole is blocked, causing the shower to not work normally. For this reason, many showers with descaling functions have appeared on the market. Generally, a descaling plate with a plurality of descaling needles is installed on the bottom of the shower, and the descaling is driven by manual or water flow. The plate moves to make the descaling needle rub against the wall of the water outlet hole, thereby eliminating the existing scale on the hole wall of the water outlet hole. Obviously, the manual descaling shower needs to be driven manua...

AI Technical Summary

Problems solved by technology

Obviously, the manual descaling shower needs to be driven manually, which is inconvenient to operate

The shower that realizes automatic descaling by the impact of water flow mainly relies on water flow to directly drive the movement of the descaling plate, and sets elastic parts for the reset of the descaling plate. The mass production of the

In addition, due to the large area of ​​the descaling plate in this method, the impact force of the water flow is dispersed, resulting in poor descaling effect in actual use
