Power instrument with good heat dissipation effect

Abstract

The invention relates to a power instrument with good heat dissipation effect. The power instrument comprises a main body and two heat dissipating devices. Each heat dissipating device comprises a horizontal pipe, a vertical pipe and a gas conveying pipe, wherein a gas guiding mechanism is arranged in the horizontal pipe, a gas conveying mechanism is arranged in the gas conveying pipe, a dust suction mechanism is arranged in the vertical pipe, the dust suction mechanism comprises a rotating assembly, a connecting pipe, a rotating pipe, a branch pipe and a plurality of filter bags, and the gasconveying mechanism comprises a lifting assembly, a piston and two closing assemblies, each closing assembly comprises through holes, blocking blocks, pressing plates, springs, coils, horizontal plates and two vertical rods. The power instrument with good heat dissipation effect adsorbs dust in the air by means of the dust suction mechanism when the air flows in the vertical pipe, ensures that clear air enters the main body, achieves good heat dissipation effect, and conveys the gas into the connecting pipe by means of the gas conveying mechanism so as to blow air to the interior of the filterbags and blow off the dust, thereby realizing the continuous dust suction capability of the equipment, and improving the practicality of the equipment.

AI Technical Summary

Problems solved by technology

[0003] When the existing power meter is running, the internal electronic components work in a closed environment, which leads to the accumulation of heat generated by the operation, which makes the temperature inside the meter gradually increase. The electronic components work in a high temperature environment, which not only reduces the measurement of the meter Accuracy, while shortening the service life of the device, a small number of instruments will add heat dissipation holes, but after long-term operation, dust and impurities are easy to accumulate on the heat dissipation holes, resulting in blockage caused by poor air circulation, reducing heat dissipation efficiency, making existing power meters reduced availability of
