A quick-release mechanism for fan includes a first lateral cover, a second lateral cover, a latch member, a handle, and a pushing member. The first lateral cover has a slot hole. The latch member extends from the slot hole and has an engaging block and an actuation portion connected to the engaging block. The handle has a first pivot end and a second pivot end pivotally connected to the first lateral cover and the second lateral cover, respectively. The handle is movable between a first position and a second position. The pushing member is disposed at the first pivot end. When the handle is at the first position, the actuation portion moves toward the first lateral cover. When the handle is at the second position, the pushing member pushes the actuation portion to move toward a direction away from the inner surface.

The present invention relates generally to the field of cooling devices. More specifically, the present invention relates to a table fan device comprised of at least one fan that is further comprised of at least one fan blade, a housing, at least one button, and at least one motor. The device may, in differing embodiments, attach itself to the underside of a table via the use of fasteners and support arms. The device is powered by a motor that rotates the fan blades around a vertical shaft to create airflow. In this manner, the device efficiently expels airflow to create an ideal climate for its users. Accordingly, the present disclosure makes specific reference thereto. Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices and methods of manufacture.

A fan includes a motor adapted to be rotated about an axis and a hub adapted to be rotated by the motor. The hub may include first and second hub parts adapted to mate to form the hub, the first and second hub parts having a gap therebetween. A plurality of fan blades each includes an end portion located in the gap formed between the first and second hub parts, which may be drawn together by a fastener to capture the blades therebetween. One or more of the fan blades may include a receiver, such as an open-ended groove, for receiving a portion of the hub. An adapter may be configured to remain stationary during use while the hub and fan blades rotate, and a portion of the hub is adapted to be selectively deployed to engage the adapter to prevent rotation of the hub. Related methods are also disclosed.

A mobile pump system for pumping water for extinguishing with an auxiliary agent, and a method therefor. The mobile pump system includes a frame for housing the pump system, a booster pump arranged in the frame, a metering pump arranged in the frame for the purpose of adding an auxiliary agent to a water flow, and a drive configured to drive the booster pump and the metering pump. The metering pump is provided with a displaceable metering pump frame and coupling means for connecting the metering pump to a container of the auxiliary agent.

A vibration damping connector system to connect between a vacuum chamber and a vacuum pump such that the vacuum pump is supported by the vibration damping connector system includes a first cylindrical member and a second cylindrical member that provide a flow passage through which gas can flow from the vacuum chamber to the vacuum pump. At least one sealing member is disposed intermediate the first and second cylindrical members to provide a gas seal and a securing system securely connect the first and second cylindrical members. At least one resilient member disposed intermediate the securing system and a cylindrical member so that when the at least one sealing member is compressed by a pressure reduction caused in use by operation of the vacuum pump, the at least one resilient member can expand to enable the securing system to maintain a secure connection.

A component carrier includes a baseboard, two sidewalls, and an ejector. The two sidewalls extend from opposite sides of the baseboard. The ejector includes a side plate, a handle, and a tab. The side plate is positioned in proximity to a first sidewall of the two sidewalls of the component carrier. The handle extends from a first end of the side plate in a first direction that is generally perpendicular to the side plate. The tab is positioned in proximity to the baseboard, and extends from a second opposing end of the side plate in a second direction that is generally perpendicular to the side plate and opposite to the first direction, the tab coupled to a first connector extending from the baseboard. The baseboard includes a first opening such that a portion of the tab of the ejector is configured to directly contact the electronic component therethrough.

Proposed is a through type drain pump for a fluid draining apparatus of a fluid pipe. The drain pump includes: a housing formed in a hollow cylindrical shape, the housing being configured such that a fluid inlet port and a fluid outlet port are in communication with each other via a fluid movement path; a rotary shaft having a driving motor, the rotary shaft being rotatably coupled to an output shaft of the driving motor via a coupler; an impeller formed at a lower end of the rotary shaft and configured to be rotated so that the fluid is moved to the fluid outlet port through the fluid movement path; and a mounter mounted at a lower outer side surface of the housing and configured to mount the drain pump on any pipe such that the drain pump is capable of being lifted and inserted into the pipe.

A frame for supporting a horizontal pumping system includes a base assembly and a motor support assembly connected to the base assembly. The motor support assembly includes an upper support plate having a top and a bottom, a first lower support plate connected to the upper support plate, and a second lower support plate connected to the upper support plate. The first and second lower support plates are connected to the upper plate with bolted and welded connections.

A draft inducer blower assembly includes a blower having a fan, a dilution air intake passage, an exhaust gas intake passage, and a discharge passage. The blower is configured to operatively connect to a heater system in a manner to facilitate flow of combustion air into a combustion chamber and to draw dilution air into the blower and to mix the dilution air with the exhaust gases and to facilitate flow of the mixed air and exhaust gases through the vent. The dilution air intake passage is positionable in at least a low flow configuration and a high flow configuration. The dilution air intake passage is more restrictive of intake of dilution air in the low flow configuration than in the high flow configuration.
