Universal cover drip guard

Abstract

The invention discloses a dropping water-preventing device for a universal hood and belongs to the technical field of universal hoods. The dropping water-preventing device comprises a cone-shaped tower, a lithium battery and a PLC programmable controller. The lithium battery and the PLC programmable controller are fixedly connected to the inner bottom end of the cone-shaped tower, the PLC programmable controller is located on the right side of the lithium battery, a T-shaped annular catch basin is fixedly connected to the lower end of the cone-shaped tower, an annular heating cavity is formedin the T-shaped annular catch basin, a heating device is connected to the bottom cavity wall of the annular heating cavity, a fixed bar is fixedly connected to the upper end of the T-shaped annular catch basin, and the left end of the fixed bar is fixedly connected to a water level sensor. The dropping water-preventing device can overcome deficiencies in the prior art, has the characteristics of being small in size, convenient, efficient, convenient to detach and use and the like, can fill the blank of dropping water carrying equipment of the universal hood, and dries the dropping water of theuniversal hood quickly so as to make sure normal use of a large instrument and to make sure that humidity of an instrument room is in a certain range.

Description

technical field [0001] The invention relates to the technical field of a universal cover, and more specifically, relates to a universal cover anti-drip device. Background technique [0002] The universal hood is a necessary ventilation device for the laboratory. Compared with ventilation fans and fume hoods, universal hoods have flexible ventilation directions, and are especially suitable for instruments that emit exhaust gas. For example, the FID detector of gas chromatography will generate a certain amount of exhaust gas when it is working, and the septum purging of gas chromatography It will also emit gas into the environment, and some large instruments will even emit harmful gases such as CO into the indoor environment. These instruments are large in size, inconvenient to move, and cannot be placed in a fume hood, so a universal hood is used for ventilation.

Problems solved by technology

These instruments are large in size, inconvenient to move, and cannot be placed in a fume hood, so a universal hood is used for ventilation.

[0003] Although the universal cover is easy to use, but in summer, when the outdoor temperature is high and the temperature of the instrument room needs to be controlled at a lower temperature, condensed water will be generated on the universal cover, and the condensed water will drip in the instrument room when it flows back. If you don't pay attention, it may even drop on the instrument, causing damage to the instrument, burning the circuit board, severely damaging the instrument, and causing unnecessary losses
