A waterproof fog instrument

Abstract

The invention discloses a fog-proof instrument and meter, which comprises a square-shaped mounting part, a short shaft, a bearing, an instrument case, an air inlet joint, a water tank, a refrigerator, a condensation pipe, a box body, a nozzle, a positioning bolt, a magnetic seat, A first blower fan, a heating cylinder, an air inlet joint, a cavity, a second blower fan, a connecting head and a heating core. The meter casing of the present invention is installed on the square-shaped mounting part through the bearing, and the bottom plate of the square-shaped mounting part is equipped with a magnetic seat, the device is fixed more conveniently, and the panel of the meter can be defogged when the defogging mechanism is working. The defogging mechanism works continuously, which can prevent fogging and facilitate the observation of the display content on the instrument panel; the cooling mechanism can make the air blown into the instrument case into a lower temperature gas, which is beneficial to improve the heat dissipation of the device in summer Capability, easy to ensure the accuracy of the instrument and the service life of the internal electrical components.

Description

technical field [0001] The invention relates to a waterproof fog instrument, in particular to a waterproof fog instrument, which belongs to the technical field of instrument application. Background technique [0002] Instruments and meters are appliances or equipment used to detect, measure, observe, and calculate various physical quantities, material components, and physical parameters. Instruments and meters are important "tools" for the development of science and technology. Instruments and meters promote science and technology in the current era. Economic development has a very important position. Vacuum leak detectors, pressure gauges, length measuring instruments, microscopes, multipliers, etc. are all instruments and meters, which are used for regulating instruments in the automatic control of industrial production processes, and distributed instrument control systems are also All are instruments.

AI Technical Summary

Problems solved by technology

[0003] Existing instruments are not easy to install and fix on the casing of the equipment when testing mechanical equipment, and installation and disassembly are inconvenient. At the same time, most of the existing instruments do not contain a defogging mechanism, and the internal electrical components of the instrument will generate heat when they are working. , when the temperature difference between inside and outside is large, water mist will form on the outer wall of the panel of the instrument, which is not conducive to personnel to observe the content displayed on the panel of the instrument. It will not only reduce the accuracy of the meter, but also reduce the service life of the electrical components inside the meter if it works for a long time, which has certain shortcomings.
