Chemical dispensing apparatus

摘要

A chemical dispensing apparatus includes a housing that is connectable to a source of water, such as a standard garden hose, and an internal space in which is disposed a rotatable container containing a quantity of chemical concentrate to be mixed with the source of water as it flows through the housing and is dispensed from the housing from a sprinkler head or misting nozzle. The flow of water through the housing powers a water turbine which is connected to the rotatable container, such that the container is rotated as water flows through the housing. In an alternative embodiment, the water turbine is replaced with an electric motor. Rotation of the container cause the chemical concentrate to dissolve which is then mixed with the water before it is dispensed through the sprinkler or mister.

主权项

1. A chemical dispensing apparatus for use in delivery of a treatment solution to a lawn, the apparatus comprising:
a main fluid supply passage configured for connection to a pipe system carrying water under pressure; a housing including an internal cavity, an end having an opening into said internal cavity, a primary discharge port and a drain port; a fluid discharge passage connecting said primary discharge port; an internal fluid supply passage connecting said main fluid supply passage to said fluid discharge passage a drain passage connecting said internal cavity to said drain port; said internal cavity connected to said internal fluid supply passage to receive a portion of a fluid flowing through said internal fluid supply passage; a float valve disposed across said drain passage and across said internal fluid supply passage, said float valve including a float that is displaced by a fluid flow through said internal fluid supply passage from said main fluid supply passage from a first position where said drain passage is open and said internal fluid supply passage is sealed by said float to a second position where said internal fluid supply passage is open and said drain passage is sealed by said float, said float returning to said first position when said fluid flow is stopped; a container removably disposed within said internal cavity and supported for rotation therein about a horizontal axis, said container configured for the reception of a chemical concentrate; a siphon tube connecting said internal cavity and said internal fluid supply passage, wherein said fluid flow through said internal fluid supply passage results in a vacuum on said siphon tube that causes fluid contained within said internal cavity to be drawn into said fluid flow through said internal fluid supply passage; a lid removably attached to said housing, said lid sealing said opening into said internal cavity when attached to said housing; an electric motor supported by said housing and operably connected to said container to rotate said container about said horizontal axis; and an electrical power supply selectively connected to said electric motor to power said electric motor.
