发明名称 Passive Christmas tree waterer and monitor
摘要 A Christmas tree irrigation and fluid monitoring system for supplying water to a conventional tree stand. A water reservoir is equipped with a translucent column through which the fluid level in the system can be monitored on a continuous basis. A tamper resistant mesh covers the top of the reservoir. The reservoir is covered with a lid forming a water tight seal. The lid is equipped with an aperture allowing air to enter reservoir while preventing from spilling if upset. The reservoir is connected to the tree stand with a conduit. The conduit is attached to the tree or the stand. The end of the conduit in the stand is fitted with a crush-resistant collar.
