Description

Sprinkler with turbocharger

Technical field

This invention relates to liquid dispensers and, more particularly, to a showerhead that is equipped with a turbocharger mechanism to effectively utilize the flow of water through the showerhead to generate electricity to provide illumination or other applications.

Background technique

Currently, there are many types of sprinklers available on the market. In order to produce different water spray patterns, such as rhythmic pulsing, centering, showing, misting, etc., all sprinklers have been designed to have complex structures and include considerable Internal parts. On the other hand, all such complex components must be housed in the sprinkler in a waterproof manner. Therefore, the manufacturing process is more complicated and the associated costs of the showerhead are more expensive. In addition, because so many fine components are packaged in a showerhead housing, there is no guarantee that all critical components will remain in an ideal fit during practice. After the product has been used for a long time, different impurities will accumulate on the surface of the shower head and block the drain nozzle.

For most users, they expect the sprinkler to be reliable but quite economical. Needless to say, such blockages that accumulate on the sprinklers will not be tolerated. First, such blockage of impurities can be disgusting and destroy the original appearance of the sprinkler. In addition, such blockages may result in interruptions in the required water spray pattern.

For everyone, the worst imaginable situation is that they are trapped in an unexpected power outage during the shower. Especially when people shower in a hotel or public bath, sudden darkness will make everything messy. Under normal conditions, other lighting components (eg, torch light) will be used to continue the shower. However, getting out of the shower and getting the lights back is extremely inconvenient and painful for most users.

Therefore, the main disadvantage of conventional showerheads is the lack of supplemental lighting components. However, how to install such lighting components to conventional sprinklers will also be difficult. On the other hand, it is not possible to carry a spare battery pack to support such lighting components.

In fact, high-speed sprinklers and the like (eg, sprinklers) are widely used in a variety of practices, such as parks, public and private grasslands, and golf courses. Quite a lot of water has been wasted. Using this water source will be environmentally friendly. Therefore, it is foreseeable that an energy-saving sprinkler having a relatively simple structure will be welcomed on the market.
