A piezoelectric ceramic air pump comprises: a pump body, a piezoelectric ceramic crystal diaphragm, and air inlet and output valves, the piezoelectric ceramic crystal diaphragm being co-central-axially mounted on the pump body to construct a working pump chamber for the piezoelectric ceramic air pump; wherein the pump body is approximately tubular, with the diameter being much greater than the axial length, and air inlet and outlet ports configured to communicate the working pump chamber with an external air passage are arranged at a position of a peripheral wall of the pump body; an air inlet and outlet component respectively laminates the air inlet and outlet valves onto the air inlet and outlet ports, such that the air inlet and outlet holes are in communication with the air inlet and outlet valves and the air inlet and outlet ports to form air inlet and outlet passages in communication with the external air passage. The air inlet and outlet ports on the side wall of the pump body help to simplify the air inlet and outlet passages for communication between the working pump chamber and the external fluid, shorten the pipeline in which the fluid flows, reduce the resistance of the pipeline, decrease the volume of the dead cavity, and improve the efficiency of fluid pumping. The number of piezoelectric ceramic crystal diaphragms may be flexibly set to one or two according to the flow rate in practice, and a lot of components are shared in the piezoelectric ceramic air pump, thereby lowering the cost of manufacturing air pumps with different powers.

A method for adapting an LED lamp tube to a fluorescent lamp tube holder, an LED lamp tube holder and an illumination device. The LED lamp tube holder comprise an adaptation bracket and a lamp tube holding clip which is connected to the adaptation bracket. The lamp tube holding clip has a circular-arc cylindrical holding surface, thereby being clamped to the outer wall of a light transmission tube of the LED lamp tube. A cylindrical pin which axially extends from the LED lamp tube holder along the light transmission tube is arranged on the adaptation bracket. The shape of the pin is the same as that of an electrically-conductive pin of the fluorescent lamp tube, thereby enabling the LED lamp tube holder to be arranged in the fluorescent lamp tube holder. The method does not need to disassemble components of an original fluorescent lamp holder, a lamp shade and the like; the LED lamp tube can be arranged on the basis of the original LED lamp tube holder; the operation is simple and quick; and the replacement cost is reduced.

Disclosed is a quantitative liquid discharge device capable of discharging liquid in a container at a preset liquid level. The device comprises a liquid discharge pipe (1), an outer sleeve (2) and a liquid level control rod (3). The liquid discharge pipe (1) is provided with a full-discharge liquid discharge port (10) and at least one internal defined-level liquid discharge port (11). Installed outside the liquid discharge pipe (1), the outer sleeve (2) is provided with external defined-level liquid discharge port (21). The wall of the liquid level control rod (3) is slidably sleeved between the wall of the liquid discharge pipe (1) and the wall of the outer sleeve (2). The liquid level control rod (3) is provided with a liquid guide port (32) passing through the wall thereof. A sliding positioning assembly is provided between the walls of the outer sleeve (2) and the liquid level control rod (3), and by means of the sliding positioning assembly, the liquid guide port (32) achieves liquid discharge at a defined liquid level, respectively between the pair of internal defined-level liquid discharge ports and the pair of external defined-level liquid discharge ports (11, 21). By operating the liquid level control rod (3) and setting the liquid level in the liquid container after discharge, the quantitative liquid discharge device can achieve liquid discharge, without specialized monitoring and control of the process of the liquid discharge, and has the advantages of quantitative liquid discharge and saving labour costs.
