Assemblies designed to facilitate detection of water flow in low water flow situations. In some embodiments, the assembly includes a channel that narrows from an inlet end of the assembly to an outlet end of the assembly to increase the velocity of water flowing through the channel. In some embodiments, the assembly may also include a water delivery mechanism that delivers water flowing through the channel to a flow sensor and enables the detection of water flow, even in low flow situations.

A floating chemical dispenser is provided, which includes: a body portion having a first chamber for receiving solid chemicals, a second chamber for receiving a floating member, and at least one first hole for communicating the first chamber with an external environment, an opening is disposed at one end of the body portion, and the opening is communicated with the first chamber; and a cover, configured to close the opening of the body portion; wherein the cover is detachably connected with the body portion via a first locking mechanism, and the first locking mechanism has a locking position and an unlocking position, and is configured to move between the locking position and the unlocking position via pressing and rotating the cover by a user, so as to control locking or unlocking of the cover and the body portion. Therefore, safety performance of the floating chemical dispenser can be improved.

A water quality management system for a water installation containing water. In some embodiments, the system includes a water quality measurement module adapted to monitor the water quality of the water in the water installation and to send water quality information to a controller; a chemical dispensing module adapted to dispense chemicals directly into the water installation in response to signals from the controller; and a communication mechanism configured to provide communication among the controller, the water quality measurement module, the chemical dispensing module and a user.

This disclosure discloses an upper end cover applied on a floating medicine dispenser and a floating medicine dispenser which comprises a main body and the upper end cover; the upper end cover comprising a cover body, at least one locking mechanism arranged on the cover body, and the locking mechanism comprises a pressing buckle, a reset component connected to the pressing buckle and a locking plate; the pressing buckle is movably mounted on the cover body through the reset component; one end of the locking plate, the end of which away from the pressing buckle, extends toward the main body of the floating medicine dispenser, and clamps into the main body of the floating medicine dispenser when the reset component is at the reset state so as to lock the upper end cover on the main body of the floating medicine dispenser.
