Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the smart respirator is mainly composed of a single-chip microcomputer control system (such as STM32F103ZET6), a temperature and humidity sensor placed outside the electric control box (such as Bosch BME280), a temperature and humidity sensor placed in the electric control box (such as Bosch BME280), a PTC type Thermistor (temperature measurement / heating) (such as Heraeus M222 series), waterproof breathable valve with embedded fan (such as Ming Yixin Mexn1504 type), and a semiconductor cooling chip (such as Peltier TES1-07101) Composition of dehumidification cabin.

[0036] Such as figure 2 As shown, the product is mainly composed of valve cover 1, valve body 4, waterproof and breathable membrane 2, fan 3, dehumidification cabin 6 and semiconductor refrigeration sheet 7 and other main components. Vent valve is installed on the side...

Abstract

The invention discloses an intelligent respirator. The intelligent respirator integrates multiple functions such as waterproof and breathable, active ventilation, intelligent heating, intelligent refrigeration and temperature and humidity monitoring. According to the environment inside and outside the electric control box, if the intelligent respirator If it is judged that there is a risk of "condensation" inside the electric control box, then according to the actual situation, the fan operation command, the PTC thermistor heating command or the semiconductor refrigeration chip cooling command are respectively executed to achieve a good "dehumidification" and "anti-condensation". Effect.

Description

technical field [0001] The invention relates to an intelligent respirator and a control method thereof, which are applied in the field of new energy vehicles. Background technique [0002] With the progress of the times, people have higher and higher requirements for product reliability. As an emerging industry, new energy vehicles have stricter requirements on the reliability of their internal components than the traditional automotive industry. At present, the waterproof and breathable valve used in the electric control box of new energy vehicles can balance the atmospheric pressure inside and outside the box, but the phenomenon of "condensation" in the box has not been effectively solved. "Condensation" mainly occurs in the environment with high humidity and large temperature difference. The "condensed water" in the electric control box is mainly due to the long-term accumulation of air with high humidity in the box, which has not been discharged outside the box; During...
