Description

Technical Field

[0001] The utility model belongs to the technical field of landscape fountains, and in particular relates to a water-type-changing waterscape nozzle controlled by a numerical control valve. Background Art

[0002] The core component of a fountain is the water sprayer. Currently, most products on the market are equipped with multiple nozzles, and the water inlet pipes are aligned with each nozzle through the forward and reverse rotation of the motor, thus presenting a variety of water patterns. To enhance the aesthetic effect, the fountain needs to spray water from each nozzle. However, the current solution requires a high-torque motor, which is achieved through the forward and reverse rotation of the motor. Such frequent and rapid switching subjects the motor to significant impact, increasing wear and tear, and significantly shortening its service life. Secondly, the size of the water splash in the existing solution is determined by the pressure of the water flow from the pump, which requires frequent frequency conversion. As a core component, the motor's subsequent maintenance costs are therefore high, and some scenic spots are even reluctant to repair fountains after they are damaged. Utility Model Content
