Description

Safety nozzle assembly for fountains 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 accessed by a person at any time.

Compared to a typical fountain that people can only see from a distance, the floor fountain is different in that it is installed so that people can easily access the area where the water spouts. However, the existing floor fountain, due to the characteristic of allowing a person's access to the installation location, always carries the risk of a safety accident. In other words, in a conventional floor fountain, the nozzle and the inside of the nozzle are always exposed to the outside regardless of the time of water injection, so the human body (especially feet or hands) of a person (especially a young high) who has approached the installation area is not affected. There was a great risk of causing a safety accident such as being caught in the nozzle installation hole or the hole around the nozzle. In addition, in the conventional floor fountain, foreign matter accumulates inside the nozzle exposed to the outside, and the nozzle does 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 normally closed and the opening is opened only when the fountain is used. On the other hand, in the prior art, devices configured to open the opening of the nozzle in conjunction with the elevation of the nozzle have been proposed. However, the conventional apparatus 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 upper end of the nozzle is spaced apart from the nozzle as the nozzle rises and the opening is opened while hitting and raising the opening/closing door covering the nozzle. There was a risk of failure due to variables (eg, accumulation of foreign matter), etc., and the nozzle had no choice but to protrude above the floor, so there was a disadvantage in that the nozzle and its surrounding parts could be damaged.
