Building material display platform data entry terminal based on internet

Abstract

The invention relates to the technical field of data terminal equipment and particularly discloses a building material display platform data entry terminal based on the internet. The building materialdisplay platform data entry terminal comprises a mounting box. A locating hole is formed in one side of the mounting box and connected with an air jetting ring. The air jetting ring is provided withmultiple air outlets. A cleaning needle is fixed to the air jetting ring. A sponge layer is bonded to the cleaning needle. A gear ring is fixed to the air jetting ring. A cleaning mechanism comprisesa cylinder body. A thin film is fixed to the top of the cylinder body. The side wall of the cylinder body is provide with an air inlet one-way valve and an air outlet one-way valve. The building material display platform data entry terminal further comprises an air collection barrel. A piston is arranged in the air collection barrel. A piston rod is fixed to the piston. A rack is fixed to the piston rod. A first air outlet pipe is connected to the air outlet one-way valve. The building material display platform data entry terminal further comprises a second air outlet pipe. A solenoid valve isarranged on the second air outlet pipe. A liquid storage tank communicates with the second air outlet pipe through a pipe. By means of the building material display platform data entry terminal, theproblem that when an existing camera is used in an environment with the severe working condition, dust and the like are likely to adhere to a camera, and thus images entered through the camera are obscure is solved.

Description

technical field [0001] The invention relates to the technical field of data terminal equipment, in particular to a data entry terminal of an internet-based display platform for building materials. Background technique [0002] A terminal is a device used by an end user to communicate with a host. Such a device could be a monitor, monitor, keyboard device, or printing device, among others. They are connected by coaxial cables to a cluster controller, which can be directly connected to a host computer or connected to the host computer through a communication controller. Multiple terminals can be connected to a single group controller at the same time. Each terminal can be connected to this group controller with an independent cable, or it can be connected to a nearby multiplexer in order to save cables, and this multiplexer is connected to a distant group controller through a single cable on the controller. [0003] Take the monitor as an example. At present, the monitor i...
