The present disclosure provides a cooling fan and a heat dissipating module including the same. The cooling fan includes a base, a tube, a bearing, a stator, a rotor, and fan blades. The base includes a base convex structure. Each of the fan blades includes a first concave structure. When the cooling fan is working, the base convex structure pass through the first concave structure on each of the fan blades. The base convex structure and the first concave structure not only increase the heat exchange area of the base but break the thermal boundary layer on the base repeatedly to improve the heat dissipating effect when the cooling fan is working.

The invention relates to a combined ceiling fan and light fixture, wherein the roots of the plurality of blades of the ceiling fan are respectively fixedly connected to a plurality of rotating components correspondingly arranged on the impeller. Each rotating component comprises a synchronous wheel, and all synchronous wheels are distributed on the bottom of the impeller with the wheel center of the impeller as the array center. Any two adjacent synchronous wheels are connected to each other by a swinging rod so that all the synchronous wheels move in the same direction with the corresponding blades. At least one swinging rod is connected with a spring for pulling the swinging rod back in the opposite direction of the centrifugal force of the blade to drive all the blades to be synchronously folded on the top of the impeller when the motor stops. The blade retraction mechanism of the invention has the advantages of high transmission precision, good operational stability, low noise and low cost.

A centrifugal heat dissipation fan including a housing and an impeller is provided. The housing has at least one inlet and at least one outlet. The impeller is disposed in the housing and rotates about an axis. The inlet is located in an axial direction of the axis and corresponds to the impeller. The outlet is located in a radial direction relative to the axis. The inlet is divided into a compression section and a release section in the rotation direction of the impeller, and the compression section has a uniform first radial dimension relative to the axis. The release section has an extended second radial dimension relative to the axis, and the second radial dimension is greater than the first radial dimension.

A heat dissipating device includes a bottom assembly, a first light guide positioned on the bottom assembly, a first light assembly positioned on the first light guide, and an outer cover positioned on the bottom assembly and at least partially enclosing the bottom assembly, the first light guide, and the first light assembly. The outer cover defines a first opening on a top surface thereof, at least a portion of the first light guide is received in the first opening, and light from the first light assembly is emitted from the heat dissipating device through the exposed portion of the first light guide.

An apparatus includes a fan module and an elongated lens. The fan module includes a housing and a cover plate having a plurality of apertures. The elongated lens includes a head portion that extends through one of the apertures of the cover plate. The head portion has a first dimension and a second dimension. The aperture also has a first dimension and a second dimension. The first dimension of the head portion is less than the first dimension of the aperture and is greater than the second dimension of the aperture. When the first dimension of the head portion is aligned with the first dimension of the aperture, the aperture permits the head portion to pass through the aperture. When the first dimension of the head portion is aligned with the second dimension of the aperture, the aperture prevents the head portion from passing through the aperture.

A vertical electric pump for moving a liquid, that includes a containment jacket a mechanical section, which includes an intake port and a delivery port, an assembly for the movement of the liquid which includes one or more impellers, spaced out by diffusers and keyed on a driving shaft, an electromechanical section, which includes an electric motor having a rotor and a stator that surrounds the rotor, the rotor being keyed on the driving shaft, and a set of instruments for the control and monitoring of its operation accessible from a single side of the electric pump.

A storable fan includes a fan head, a support rod and a base that are connected detachably. A first accommodating groove and a second accommodating groove are formed in the base, and the storable fan has a used state and a stored state. In response to the used state of the storable fan, the fan head, the support rod and the base are connected sequentially. In response to the stored state of the storable fan, the fan head is stored in the first accommodating groove, and the support rod is stored in the second accommodating groove. The fan head, the support rod and the base are connected detachably, for ease of detachment of the storable fan. Both the fan head and the support rod can be stored in the base. The storage process can be accomplished without detaching such fasteners as screws and nuts or by only using few fasteners.

A ceiling fan is provided. The ceiling fan includes one or more fan blades. The ceiling fan further includes a motor. The motor is operatively coupled to the one or more fan blades. The motor is configured to drive rotation of the one or more fan blades. The ceiling fan further includes a light kit. The light kit includes a panel. The panel has an edge extending between a top surface of the panel and a bottom surface of the panel. The light kit further includes at least one light source positioned to illuminate the edge.

A cooling device includes a frame including a base portion and a barrel portion connected to the base portion, a fan assembly including a hub and a plurality of fan blades connected to the hub, the fan assembly rotatably coupled to the frame via at least one bearing positioned between the barrel part and the hub, a driving assembly disposed on the frame, and a decorative plate having a marking and a column coupled thereto and extending therefrom. The decorative plate is coupled to the base portion using the column and is stationary with respect to the fan assembly. The cooling device further includes a light assembly disposed on the driving assembly and emitting light that illuminates the marking.

A ventilation fan includes a fan unit, a cover, a speaker and an outer cap. The fan unit has an air inlet and an air outlet. The cover is disposed on the air inlet and has an opening disposed corresponding to the air inlet. The speaker is detachably disposed on the cover. The outer cap is disposed on the air inlet. The cover is located between the fan unit and the outer cap, and the outer cap has a plurality of through holes configured as both of ventilation channels and sound output channels.
