Discloses is a micro-pump that includes a pump body having a compartmentalized pump chamber, with plural inlet and outlet ports and a plurality of membranes disposed in the pump chamber to provide compartments. The membranes are anchored between opposing walls of the pump body and carry electrodes disposed on opposing surfaces of the membranes and walls of the pump body. Also discloses are applications of the micro-pump including as a heat remover and a self-contained continuous positive airway pressure breathing device.

A single-arm micro air-pressure pump device, having an air pump body and a driving unit. The air pump body includes a supporting frame, an air chamber unit coupled to a side of the supporting frame, and a swing arm provided on the air chamber unit. The driving unit is fixed on the supporting frame and has an output shaft. The output shaft is provided with an eccentric shaft and is configured to rotate the eccentric shaft, and the eccentric shaft has an end coupled to the output shaft and an opposite end coupled to the swing arm in order to drive the swing arm into a reciprocating motion between at least a proximal position and a distal position with respect to the air chamber unit. The reciprocating motion pushes a piston unit provided on one end of the swing arm and causes the air output.

A vaporizer apparatus includes a pump housing, a main housing containing an evacuation chamber, and an operation unit attached to the main housing. The operation unit selectively seals the evacuation chamber off from communication with an air inlet. One or more pumps in the pump housing is/are operable to generate a vacuum in the evacuation chamber. A mouthpiece is attached to the main housing, and may be selectively placed in communication with the evacuation chamber. When oil is placed in the evacuation chamber and the operation unit is operated, the evacuation chamber is temporarily sealed off from the inlet, creating a vacuum sealed chamber connected with the pump(s). Then, the pump(s) is/are activated to reduce pressure in the evacuation chamber, and the oil is vaporized at an ambient temperature without requiring a heater. When the operation unit is released, the evacuation chamber is emptied via the mouthpiece.

An air quality system handled by artificial intelligence internet of things is provided and includes a gas detection device, an artificial intelligent internet of things handling device, and a user demand platform. In the system, the user demand platform transmits an instruction to the artificial intelligent internet of things handling device. By using self deep-learning analysis of data computing and algorithms of the AI device, second digital data is generated. The second digital data is fed back to the gas detection device through the network. Accordingly, the actuating actions of the micro pumps and the detecting actions of the sensors can be generated. Hence, the actuation and the detection of air quality can be achieved more effectively.

A pump assembly includes a pneumatic pump with a pump body having a discharge passage. The pump is operable to discharge compressed air through the discharge passage. The pump assembly also includes a cap adjacent the pump body and at least partially enclosing a first volume in communication with the discharge passage, and a casing at least partially surrounding the pump. The pump assembly further includes a second volume defined between the casing and the cap, the second volume in fluid communication with the first volume via an opening in the cap, and a casing outlet in fluid communication with the second volume. The pump assembly is configured such that the compressed air flows through the first volume and the second volume before being discharged from the casing through the casing outlet.

An electrochemical compressor, including a first end plate, a second end plate, a voltage supply connected to the first end plate and second end plate, a plurality of membranes, where each membrane of the plurality of membranes has a substantially same impedance, and where each membrane of the plurality of membranes has a different thickness in a stacking direction, and a plurality of conductive bipolar plates, where the bipolar plates of the plurality of bipolar plates are arranged in contact with, and alternating in the stacking direction with, the membranes of the plurality of membranes, and where the membranes of the plurality of membranes and the bipolar plates of the plurality of bipolar plates are electrically connected in series between the first end plate and second end plate.

A method of producing a flow of a fluid through a passage (24) defined in a rigid frame (22) comprises selectively actuating a flexible membrane (38) disposed across a midpoint of the passage (24) with an actuating system in a manner which produces a wave-like motion in the membrane (38) thereby causing a peristaltic movement of the fluid through the passage (24).
