An air circulator includes a blower unit that is provided with an airflow opening on a front side of the blower unit. A grill is provided in the airflow opening, and is provided with airflow guide blades in a spiral manner Each of the airflow guide blades is convex toward an airflow direction between its inner end portion and its outer end portion to form the grill three-dimensionally. The grill further includes a circular ring that intersects with the airflow guide blades.

An apparatus includes a fan having a fan housing with guidance members extending from opposing sides of the housing, wherein the fan housing has a depth that is less than a height and width. A handle is pivotably coupled to the fan housing, and guidance tracks are positioned on opposing sides of an open channel. Each of the guidance tracks has a first track portion extending from a first face of a chassis in a first direction into the chassis and a second track portion extending from the first track portion in a second direction. The guidance members move along the corresponding guidance tracks, wherein the fan housing moves along the first track portion in a sideways orientation and reaches an operating orientation in the second track portion.

A luminous fan connection structure. The luminous fans are disposed adjacent to each other in a side-by-side manner. A blade is arranged in a frame base. A light guide ring combined with a light-emitting module is arranged annularly outside the blade. The frame base has a fan circuit board and a snap portion. The fan circuit board is electrically connected to the blade and the light-emitting module. The external connector includes a board seat and a connection circuit board. The board seat includes a pair of hooks. The connection circuit board includes a first and a second conductive pin. The board seat straddles between luminous fans. The pair of hooks are respectively fastened with the snap portions of the adjacent luminous fans, and the first conductive pin is electrically connected to one fan circuit board, and the second conductive pin is electrically connected to another fan circuit board.

A system for controlling operation of first and second electric fans is provided. The system includes a microcontroller that determines when first analog multiplexer is malfunctioning or a first channel of the first analog-to-digital converter is malfunctioning based on first values obtained from the first analog-to-digital converter. The first values are associated with at least one of a first speed signal associated with the first electric fan and a first driving voltage for the first electric fan that are received by the first analog multiplexer. The microcontroller modifies a control signal to induce the second electric fan to operate at a higher rotational speed when the first analog multiplexer is malfunctioning or the first channel of the first analog-to-digital converter is malfunctioning.

A blower configured to be positioned in confined spaces and to provide ventilation of a fluid, such as temperature controlled air, is disclosed. In various embodiments, the blower is configured to have a reduced axial thickness, which can be desired in such confined spaces. In some embodiments, the blower has an integral filter, a wire channel for the routing of one or more wires, and/or an exposed backplate. In some embodiments, the blower has a snap-fit circuit board, containment system for mounting the motor, one or more vanes for directing fluid flow, shrouded impeller, and/or integrated connector.

Disclosed herein is a user interface that can be universally mounted to a combination variable speed pump and a drive assembly therefor. The user interface is universally configured to be selectively mounted to the drive assembly and/or to an environmental surface that is remotely located from the drive assembly. The user interface is universally configured to be selectively mounted to the drive assembly in any one of a plurality of available positions relative thereto.
