A light-emitting fan includes a fan frame, an impeller, a circuit board and a light-emitting component. The impeller includes a light guiding hub and a plurality of blades. The light guiding hub is disposed on the fan frame. The light guiding hub has an outer top surface, an outer annular surface, an inner annular surface, and a recess. The outer annular surface is connected to the outer top surface, the inner annular surface faces away from the outer annular surface. The blades are connected to the outer annular surface. The recess is located at the inner annular surface so as to form a light guiding protrusion of the light guiding hub. The circuit board is disposed on the fan frame. The light-emitting component is disposed on the circuit board. Light generated by the light-emitting component is emitted from the outer top surface through the light guiding protrusion.

A concealed office fan lamp is provided, which includes a stop device, a support and a fan blade. A lamp is arranged at the bottom of the support, a cavity is arranged in the support, the fan blade is electrically connected with a driving mechanism to make it rotatably arranged in the cavity, and the stop device is arranged on the support and/or the fan blade to detect the motion state of the fan blade. According to the motion state, the fan blade is stopped and hidden in the cavity. By providing a stop device on the fan lamp, the fan blade can be accurately stopped and hidden in the cavity, the person under the fan lamp cannot see the fan blade when the fan lamp stops working, making the fan lamp more beautiful as a whole.

A neck-hanging fan, comprises a housing that can be worn on the neck and a fan assembly, wherein the two extended tail ends of the housing are provided with an accommodating chamber, and an air duct communicating with the accommodating chamber is formed in the housing, a fan assembly is arranged in the accommodating chamber, an air inlet hole communicating with the accommodating chamber is arranged on the housing, and a plurality of air outlet holes communicating with the air duct are arranged on the outer wall of the housing, and the plurality of air outlet holes are distributed along the extension direction of the air duct. The end of the air outlet away from the fan assembly is provided with a wind gathering plate extending into the air duct, wherein a plurality of wind gathering plates are provided.

The present invention relates to a fruit or vegetable shaped fan for dispersing airborne eye irritants that are released during cutting fruits or vegetables. The fan includes a base that is wedge-shaped, an air inflow collimator that is fruit or vegetable shaped having an open front end, an internal frame that is configured to provide minimal abatement to airflow through the air inflow collimator, a motor mount that secures a motor, a fan blade that attaches to the motor, and a grill that attaches to the open front end of the air inflow collimator. The fan is configured to disperse airborne eye irritants away from a user's eyes. Airborne eye irritants are released when certain fruits and vegetables are chopped or otherwise cut. Such fruits and vegetables that can release airborne eye irritants when cut include onions, peppers, and certain other fruits and vegetables.

A circulator is described that is configured to circulate liquids such as water, chemical mixtures, suspensions and the like. The circulator has an oscillation shaft disposed within, for example concentrically disposed within, a support tube that is used to mount the circulator to a support structure. Locating the oscillation shaft within the support tube makes the circulator more compact, achieves better alignment of the oscillation shaft and the support tube, and makes the circulator stronger compared to a circulator where the oscillation shaft is not disposed within a support tube. In one embodiment, the circulator can be used to create a continuous flow of water in a body of water including around marinas, areas around docks, and waterfronts.

A ceiling fan with a ceiling projection function includes a ceiling fan body and a ceiling fan housing. The ceiling fan body includes a plurality of blades, a motor that drives the blades to rotate, and a hanging rod. The ceiling fan housing is provided with a pattern hole unit and a light-emitting unit. The pattern hole unit has at least one pattern hole. The pattern hole of the pattern hole unit passes through the ceiling fan housing. The light-emitting unit has at least one light-emitting member. When in use, the light-emitting member of the light-emitting unit projects a light beam passing through the pattern hole of the pattern hole unit to project a pattern of the pattern hole of the pattern hole unit outside the ceiling fan housing and above the blades.

A system for controlling operation of a ceiling fan is provided. The ceiling fan includes a fan device and a light device, and can be operated via a user operation module that is to be operated by direct operation, or a wireless receiver module that receives a wireless control signal. Within a predetermined control duration from the time of activation, the ceiling fan can, upon receipt of an operation signal from the user operation module or a wireless control signal from the wireless receiver module, switch to operate in a mode where the ceiling fan is controlled via one of the user operation module and the wireless receiver module that corresponds to the signal received thereby.

A system for cooling a circuit component on an electronic device includes a closed-loop cooling circuit and a coolant filling device. The closed-loop cooling circuit includes a coolant block, a first pump and a radiator. The coolant filling device includes a container, a base and a second pump disposed inside the base. The coolant filling device is configured for attachment to the cooling circuit. In some embodiments, when the coolant filling device is attached to the cooling circuit, coolant may be circulated from the coolant filling device to the cooling circuit while the cooling circuit circulates coolant. In further embodiments, when the coolant filling device is attached to the cooling circuit, coolant may be circulated from the coolant filling device to the cooling circuit while the electronic device remains powered on.

An integral fan blade includes a fan blade connecting disk and a plurality of fan blade bodies arranged around and equidistantly surrounding the fan blade connecting disk. The fan blade bodies and the fan blade connecting disk are integrally formed. This design allows the wind angle to cover a cone-shaped area from top to bottom. Under the same specifications, the wind force is relatively larger than ordinary conventional fan blades, and the coverage area is also larger, thus bringing better blowing effect and better use effect to users.
