The present invention relates to a storage container for ink having a chamber (2) for ink (4) and at least one float (10) vertically movable in the chamber (2), the float floating on the ink (4) and spaced apart from the walls (3) of the chamber (2), and the float almost completely covering the surface (5) of the ink (4) and thus preventing contact with air (7) or gas (7), characterized in that the float (10) is centered between the walls (3) of the chamber (2) by a magnet (12). The invention also relates to an inkjet printer having at least one printing unit comprising a plurality of printheads (32) and at least one storage container (1) according to the invention. The invention advantageously ensures a trouble-free ink supply. The invention is preferably used in industrial inkjet printers.

This invention discloses a constant illuminance adjustment method and an apparatus thereof, comprising the following steps: initialization setting: setting an initial illuminance value representing the device's brightness, and setting a constant illuminance value representing the desired ambient illuminance; real-time acquisition: acquiring the actual ambient illuminance value representing the real-time ambient illuminance, and monitoring the real-time illuminance value representing the real-time device brightness; comparison and judgment: comparing the actual ambient illuminance value with the constant illuminance value, and simultaneously comparing the initial illuminance value with the real-time illuminance value, adjusting the real-time illuminance value based on the two comparison results to bring the actual ambient illuminance value closer to the constant illuminance value; this invention aims to provide a constant illuminance adjustment method and an apparatus thereof, which can realize automated constant illuminance adjustment and reduce labor costs.

The utility model relates to a peristaltic pump pump shell, including lower casing, baffle and upper casing, baffle and lower casing surround the drive cavity for installing transmission assembly, and the upper casing and baffle surround the rotor cavity for installing rotor, baffle is provided with the through -hole, and one end of baffle upper end surface is provided with two first bosses, and the other end of baffle upper end surface is provided with two second bosses, and first boss is provided with first arc plate between through -hole, the both ends of upper casing are provided with two recesses respectively, and recess and first boss match, and recess and second boss surround the pipe -through hole for hose to be inserted, and two second arc plates are provided with in the upper casing symmetry, and two second arc plates and first arc plate surround the hose and resist the board of the open mouth towards pipe -through hole. Through the direction of baffle can be realized peristaltic pump interface direction's change, to save the use of adapter, save the installation cost, improve the installation efficiency.

This utility model belongs to the technical field of reversing light drive circuits, specifically an integrated drive circuit for a rear fog reversing light, including a rear fog light control module, a reversing light control module, and an LED chip module. The rear fog light control module is connected to both the reversing light control module and the LED chip module. The LED chip module is also connected to both the rear fog light control module and the reversing light control module. In this application, the LED driver ensures that the LED current remains constant when the input voltage changes from 9V to 16V, allowing the LED brightness to vary within a small range, thus ensuring consistent product brightness. It simplifies the assembly process, reduces manual soldering and wiring harness installation time, and improves production line efficiency. Compared to discrete component circuits, the LED driver chip-level integrated solution has stronger vibration and electromagnetic interference resistance, reducing the probability of failure.
