Provided is an electronic fountain candle, comprising a transparent or semitransparent outer cylinder (9), a battery compartment, a flow-guiding cover (10), an LED/water pump assembly (4), and a control board (3). The outer cylinder (9) is a hollow tube body. The battery compartment is an inverted cup-shaped body, the opening of the cup facing down, the bottom of the cup being on the top, and the cup-shaped body being sleeved inside the outer cylinder (9). A water storage chamber is located at the interior wall of the outer cylinder (9), above the bottom of the battery compartment cup. The LED/water pump assembly (4) is mounted inside the water storage chamber, and comprises: being equipped with an LED-PCB board (42) for an LED, as well as a water pump (43) and a water drainage pipe (41). The LED-PCB board (42) is waterproofed, and the water outlet of the water pump (43) is connected to the water drainage pipe (41). The flow-guiding cover (10) is provided with a flow-guiding hole, and the water drainage pipe (41) is in communication with the flow-guiding hole. The peripheral edge of the flow-guiding cover (10) is lower than the upper end face of the outer cylinder (9), and there is a gap, used for draining water, between the flow-guiding cover (10) and the inner wall of the outer cylinder (9). The control board (3) is mounted inside the battery compartment, and the LED/water pump assembly (4) is electrically connected to the control board (3). The LED of the electronic fountain candle simulates the weak light of a conventional lamp, while the circulation of water simulates the sound of flowing water in a natural environment, creating a natural and tranquil ambiance.

A bowl is attached to a drip irrigation system at an emitter, so that the bowl can be filled with water in an automated fashion, using the control timer and solenoid valves of the existing irrigation system. The emitter has a stem and a head. The stem extends through a hole in the sidewall of the bowl so that the head rests against the sidewall of the bowl. Preferably the head is flush with the sidewall of the bowl and forms a water-tight seal with the sidewall of the bowl. Drip irrigation tubing is attached to the stem of the emitter and connected to the drip irrigation system. A through-hole runs through the emitter to permit water to flow from the drip irrigation tubing through the stem and head into the bowl. An in-line valve between the water source and the emitter improves control of the water through the emitter.

A water spraying device and an above-ground pool including the water spraying device are provided. The water spraying device includes: a sprayer assembly having a water inlet end, a water outlet end, and a first magnetic element disposed on the water inlet end; and a mounting assembly including a first end, a second end in fluid communication with the first end, and a second magnetic element disposed on the first end of the mounting assembly. The mounting assembly defines therein a water passage to the sprayer assembly. The first magnetic element is mutually attractive to the second magnetic element such that the water inlet end of the sprayer assembly and the first end of the mounting assembly are detachably connectable via the first magnetic element and the second magnetic element.
