Abstract: According to an embodiment of the present disclosure, a ceiling fan includes a shaft coupled to a ceiling or a wall surface, a housing cover provided at a central axis thereof with a shaft and receiving a motor assembly and an electronic unit, and a blade coupled to the housing cover. The electronic unit is provided in a multi-stage.

Abstract: A toilet bowl of a toilet, the toilet bowl comprising: a toilet base bowl comprising an upper portion and a toilet rim disposed in the upper portion of the toilet base bowl. The toilet rim comprises a tubular structure comprising a first end configured to receive water, a second end, and a middle section disposed between the first end and the second end. The water is configured to flow in a water flow direction towards the second end, and the second end is closed. The toilet rim also comprises a plurality of outlet conduits extending from the middle section directed towards an interior of the toilet base bowl. The plurality of outlet conduits is directed at an acute angle relative to the water flow direction, such that plurality of outlet conduits allow the water to enter the interior of the toilet base bowl in a swirl-flow manner.

Abstract: Described herein is a method of controlled exposure of ultraviolet (UV) rays to a user, with use of a UV exposure system comprising a camera unit, a UV source, and a microcontroller. The method includes capturing an image of the user; performing face recognition on the captured image to identify a user profile; obtaining information on dosage value delivered to the user in a defined amount of dosage time period; comparing the dosage value with a threshold value; and performing an action on the UV source based on the comparison. The action includes: activating the UV source if the dosage value is below the threshold value; and deactivating the UV source, if the dosage value is above the threshold value.

Abstract: A ceiling fan may include a shaft coupled to a ceiling, a cover to surround the shaft, a main blade having a blade hole which is a space open inward, and a sub-blade positioned in the blade hole. The sub-blade is disposed to have an angle of attack different from an angle of attack of the main blade. The ceiling fan may resolve a red zone of the air flow and may improve air volume and the flow rate due to the dual blades.

Abstract: The assembly arrangement comprises a reservoir (10) on which a filling container (20) having a bottom wall (21) is mounted; and a filter(30) mounted to said bottom wall (21) which presents a seat portion (24) provided of one or more windows (25a) and bearing a stopper element (40) provided of at least one opening (41 a) and moveable between a closed position and an open position of the seat portion (24). The filter (30) is upwardly seated against the bottom wall (21) and coupled to the stopper element (40), allowing the filter (30) to be moved between a release and assembly position, with the stopper element in the closed position, and an assembled position, moving the stopper element (40) to its open position and to which remains axially hold against said bottom wall (21), communicating inlet orifices (31a) of the filter (30) to the interior of the filling container (20).
