Abstract
The invention relates to a ventilating fan, in particular to an intelligent ventilating fan. The intelligent ventilating fan comprises a ventilating fan and a formaldehyde sensor, and the formaldehyde sensor is arranged in the ventilating fan. The intelligent ventilating fan has the advantages that formaldehyde concentration is measured through the formaldehyde sensor, and the ventilating fan is triggered to be started automatically.
Description
Technical field
The present invention relates to ventilation fan, relate in particular to intelligent ventilation fan.
Background technique
Formaldehyde causes human nasopharyngeal carcinoma, CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer, and can cause leukemia.According to state compulsory standard, after closing the doors and windows 1 hour, in every cubic metre of indoor air, burst size of methanal must not be greater than 0.08 milligram; As reaching the 0.1-2.0 milligram, 50% normal person can smell foul smell; Reach the 2.0-5.0 milligram, eyes, tracheae will be subjected to intense stimulus, occur sneezing, symptom such as cough; Reach more than 10 milligrams expiratory dyspnea; Reach more than 50 milligrams, can cause critical illness such as pneumonia, even cause death.Long-term contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma, colon cancer, brain tumor, paramenia, nuclear gene mutation, in the dna single chain commissure and DNA and protein commissure and suppress dna damage reparation, pregnancy syndrome, cause neonatal chromosome disorder, leukemia, cause the decline of teenager's memory and intelligence.
Ventilation fan by with the air exchange of indoor and outdoor, keep IAQ good, and common ventilation fan all is to need the people initiatively to open.
Summary of the invention
In order to solve the problem of above-mentioned existence, the purpose of this invention is to provide intelligent ventilation fan.
To achieve these goals, the present invention is by the following technical solutions:
The intelligence ventilation fan comprises ventilation fan and formaldehyde sensor, and formaldehyde sensor is located in the ventilation fan; Its beneficial effect is by formaldehyde sensor measurement concentration of formaldehyde, to trigger ventilation fan and open automatically.
In some embodiments, formaldehyde sensor is electrochemical sensor; Its beneficial effect is by electrolyte and tested formaldehyde gas generation chemical reaction, to play the effect of measuring concentration of formaldehyde.
In some embodiments, ventilation fan is provided with display screen; Its beneficial effect is to make that recording concentration of formaldehyde is presented on the display screen.
Description of drawings
Fig. 1 is the schematic representation of the intelligent ventilation fan of embodiment of the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Fig. 1 has schematically shown the intelligent ventilation fan according to one embodiment of the present invention.As shown in the figure, this intelligence ventilation fan comprises: ventilation fan 1 and formaldehyde sensor 2, formaldehyde sensor 2 is located in the ventilation fan 1.Wherein ventilation fan 1 lower end is provided with display screen 3, and formaldehyde sensor is electrochemical sensor.
After ventilation fan was connected power supply, detector was started working, and detected gas and entered formaldehyde sensor 2; Formaldehyde sensor 2 arranges working electrode in its electrolytic cell, to electrode and reference electrode, and impose certain polarized voltage, separates with film and the external world; Tested gas permeation film arrives working electrode, redox reaction takes place, sensor 2 outputs this moment one electric current, concentration of formaldehyde is more big, electric current is more big, otherwise it is more little, output current is through the amplification circuit amplified current, converting voltage signal to through the I/V change-over circuit, change into digital voltage signal finally by the A/D change-over circuit, import processor into, after processor is handled the digital voltage signal that receives, export the concentration of formaldehyde value information that calculates to display screen 3, thereby concentration value is presented on the display screen 3.When concentration value more than or equal to 0.08mg/m
3The time, processor triggers the ventilation fan ventilation, to reduce formaldehyde content.When the concentration of formaldehyde value less than 0.08mg/m
3The time, ventilation fan stops ventilation.
Above-described only is embodiments of the present invention.For the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
