Description

Fountain safety nozzle assembly with automatic opening and closing function {nozzle assembly fountain safety}

The present invention relates to a safety nozzle assembly for a fountain, and more particularly, to a safety nozzle assembly for a fountain having an automatic opening and closing function, which can be advantageously applied to a floor fountain that can be frequently accessed by people.

Compared to typical fountains that people can only see with their eyes from a distance, floor fountains are different in that they are installed so that people can easily access the area from which water is spouting. However, existing floor fountains always had a risk of safety accidents due to the characteristics of allowing people to approach the installation location. In other words, in conventional floor fountains, the nozzle and the inside of the nozzle tube are always exposed to the outside regardless of when water is sprayed, so the human body (especially the feet or hands) of a person (especially a young child) approaching the installation area There was a high risk of causing safety accidents such as being caught in the nozzle installation hole or the hole around the nozzle. In addition, in the conventional floor fountain, foreign substances are accumulated inside the nozzle exposed to the outside, and the nozzle may not function properly. In addition, the existing nozzle has a high risk of being damaged by a person.

Accordingly, there is a need for a floor fountain in which the opening of the cover covering the nozzle is closed at normal times and the opening is opened only when the fountain is used. In contrast, conventionally, devices configured to open the opening of the nozzle in conjunction with the elevation of the nozzle have been proposed. However, the conventional device has a disadvantage in that the structure for opening and closing the opening corresponding to the elevation of the nozzle is complicated and many parts are required. In particular, the conventional device has a structure in which the nozzle is raised and the opening is opened by hitting and raising the opening and closing door covering the nozzle while the upper end of the nozzle is spaced apart from the nozzle. There is a risk of failure due to a variable (eg, accumulation of foreign matter), etc., and the nozzle has no choice but to protrude above the floor, so there is a high risk of damage to the nozzle and its surrounding parts.
