A fan receiver assembly (1200) includes a fan receiver (101). The fan receiver includes a rear wall (128) and at least one sidewall (112). At least one deformable clasp (105) is coupled to, and translatable along, the sidewall. The deformable clasp includes at least one latching arm (142) that is pivotable between an axially displaced open position occurring when the latching arm extends beyond a terminal end sidewall and a parallel position occurring when the latching arm is situated between the terminal end and the rear wall. The sidewall defines a d-track (111) having a terminal end (125) and an outward notch (126). A follower situates within the d-track between the deformable clasp and the sidewall. A fan module (102) latches to the fan receiver assembly when the follower situates within the outward notch.

A vacuum pump comprises: a pump main body; a heater provided at the pump main body; a power source device configured to supply power to the pump main body; a cooler provided between the pump main body and the power source device; a connection plate provided between the pump main body and the cooler; a first heat insulating plate arranged between the cooler and the connection plate; and a second heat insulating plate arranged between the pump main body and the connection plate.

The invention relates to a fastening apparatus (1) for fastening a ventilator (2) to a carrier structure, having—at least two support elements (3a, 3b), each being connectable at the first end (4) thereof to the carrier structure, wherein at least two of the support elements (3a, 3b) have a fastening means (5) for fastening a ventilator (2), wherein—the support elements (3a, 3b) are connected at the second end (7) thereof to the adjacent support element (3a, 3b), such that the support elements (3a, 3b) mutually support each other, wherein—the fastening means (5) is spaced apart from a connection point (17), at which the second end (7) is connected to the adjacent support element (3a, 3b).

A fan assembly and an inverter are provided. The fan assembly includes a fan guard, a fan body and a noise reduction mounting member. The fan body directly faces an air inlet, the air inlet is covered by a fan guard, and the noise reduction mounting member is arranged on the fan body, to provide a preset distance between the fan body and the fan guard, and the noise reduction mounting member is configured to mount the fan body on a to-be-mounted component in a buffered manner. The distance between the fan body and the fan guard can reach the preset distance due to the noise reduction mounting member. In addition, the noise reduction mounting member plays a vibration isolation function between the fan body and the to-be-mounted component, which improves the sound quality.

A fan and an electronic device are provided. The fan includes a hub, an outer frame surrounding the hub, and a plurality of blades connected between the hub and the outer frame. The outer frame includes a first side facing an air inlet of the fan, a second side facing an air outlet of the fan, and an inner wall between the first side and the second side. Each of the plurality of blades includes a first end connected to the hub and a second end connected to the outer frame. The second end includes a first region and a second region, the second region is connected to the inner wall. The first region extends from the second region and is disposed above the first side. A first notch is defined among the first regions of two adjacent blades and the first side.

A ceiling fan assembly can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a ceiling fan mount with a canopy. The canopy can be received by a mounting bracket to enclose the mounting hardware near the ceiling.

The present invention provides a remote-controlled, retractable accessibility device for ceiling and wall fixtures, such as for lighting fixtures, ceiling fans, speakers, mobiles, and the like. The device allows for the raising and lowering of the fixture via a remote wireless or wired control. The device is designed with electrical connectors that automatically disengage and reengage to cut off the flow of electricity when the fixture is lowered so that the fixture can be safely accessed.

Embodiments of the present invention provide systems and methods for mounting an electrically-powered device to a ceiling or other supporting structure. The electrically-powered device can be, for example, a ceiling fan, a ceiling fan with a lighting fixture, or a lighting fixture.

A blower unit can include an outer housing, an inlet subassembly, a fan subassembly, an outlet subassembly, and a grommet. The outer housing can have an aperture extend along a first axis between first and second ends. The inlet subassembly can be received in the first end of the aperture. The fan subassembly can be received in the aperture adjacent to the inlet subassembly and include at least one wire. The outlet subassembly can be received in the second end. The grommet can be positioned between at least part of the second end and the outlet subassembly. The at least one wire can extend through the grommet. The grommet can seal against the at least one wire. The grommet can seal between the outer housing and the outlet subassembly.

The invention relates to a method for producing a drive unit device, in particular a fan device, which has at least one first modular unit (12) and at least one second modular unit (16), which concentrically accommodates at least a portion of the first modular unit (12), with the first and second modular units (12, 16) being intended to contribute mechanically to a change in torque, and the first modular unit (12) being secured in the second modular unit (16) in at least one method step (100, 110). To increase safety and reduce process costs, it is proposed that the first modular unit (12) be secured in the second modular unit (16) by means of at least one concentric pressing process step.
