A ceiling fan blade fastening structure includes a base and a fan blade. The base is fixed to a rotor of a motor of a ceiling fan. The base has a bottom wall and a peripheral wall. The peripheral wall has a slot. The bottom wall is provided with a guide rail portion adjacent to the slot. The bottom wall is provided with a bracket and a positioning block behind the guide rail portion. The fan blade has a tongue portion to be inserted into the slot and pressed against the positioning block, so as to position the fan blade. The tongue portion is provided with a stop block to be against the rear of the bracket, so that the fan blade is unable to be disengaged from the slot.

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.

The present disclosure provides an inflation product with a built-in air pump, including an air pump (1), a connection piece (2) and an inflation product (15). The inflation product (15) includes a through hole (151) penetrating from inside to outside, the connection piece (2) is fixed at an opening of the through hole (151), the air pump (1) and the connection piece (2) are detachably connected, and the through hole (151) is provided for the air pump (1) to protrude into with a front end of the air pump (1) exposed outside the through hole (151). The front end of the air pump (1) includes an air inlet (3) in which a normally-closed switch is mounted, and an air inlet sealing cover (5) for driving the normally-closed switch (4) to be pressed down is covered on the air inlet (3).

A motor control system providing at least seventeen speed settings using industry standard control signals and an industry standard five pin speed connector. One speed monitoring pin transmits an output signal for monitoring the speed of the motor, and four speed setting pins receive input signals for setting the speed. One of the speed setting pins receives and decodes two binary states and two frequency states, thereby providing a total of thirty-two speed settings. A non-regulated isolated winding is added to an internal transformer to provide an internal isolated flyback power supply for the motor, thereby liberating a pin on the industry standard five pin speed connector to provide the fourth speed setting input pin. Transmission circuitry is associated with the speed monitoring pin, and the non-regulated isolated winding is used to provide a direct current bias to the transmission circuitry.

A handheld fan includes a housing, a fan assembly mounted in the housing and close to a rear portion of the housing, a semiconductor chilling plate mounted in the housing and arranged in front of the fan assembly, and a cold conducting piece arranged on a front end of the housing. A front end surface of the semiconductor chilling plate is a cooling surface. The cold conducting piece is attached to the front end surface of the semiconductor chilling plate. An air outlet is defined between the cold conducting piece and the housing.

An air moving device includes a housing member, an impeller assembly, and a nozzle assembly. The nozzle assembly can include one or more angled vanes set an angle with respect to a central axis of the air moving device. The air moving device can output a column of moving air having an oblong and/or rectangular cross-section. A dispersion pattern of the column of moving air upon the floor of an enclosure in which the air moving device is installed can have an oblong and/or rectangular shape. The dimensions of the dispersion pattern may be varied by moving the air moving device toward or away from the floor, and/or by changing the angles of the stator vanes within the nozzle assembly.
