Description

Indoor air quality detector

Technical field

The utility model relates to the monitoring equipment field, is the indoor air quality detector that the monitoring volatile organic compounds is lived people.

Background technology

VOC is the abbreviation of volatile organic compounds, and it is meant in room temperature and is present in organism in the air with the form of evaporating.Its toxicity, pungency, carcinogenicity and special smell can influence skin and mucous membrane, and human body is produced acute lesion.VOC gas is mainly from fuel combustion and communications and transportation; In the interior decoration process, VOC is the killer who causes indoor environmental pollution mainly from paint, coating and tackifier.When its content reaches finite concentration, can make the people feel headache, feel sick, vomit in the short time, and may cause failure of memory, the liver of harm people, kidney, brain and nervous system.Because VOC gas is the particle that can not filter with air cleaner, the simplest, the effective method of avoiding these harmful VOC gases is the well-off fresh air of frequent ventilation.Air quality detector does not come into the market as yet as masses' the consumer goods at present, does not have the similar techniques scheme yet and discloses.If, in decorating the process of FASHIONHOME, produce the VOC gas content and exceed standard and cause civil disputation, then be to entrust to fulfil monitoring by legal mechanism for monitoring, resolve through consultation by both parties again or by court decision.

Summary of the invention

The purpose of this utility model provides a kind of indoor air quality detector, making it can solve legal mechanism for monitoring does not monitor before the VOC content in the room air as yet, VOC content is a kind of unofficial in just can the self check air, indoor air quality detector that can property for referencial use.To strengthen people, the air of institute living space there is the theory of a matter to environmental protection consciousness.The purpose of this utility model realizes by the following technical solutions.

A kind of indoor air quality detector, this detecting device comprise housing, LCD display, single-chip microcomputer and supporting functor, and the front of its housing 1 is provided with display screen 2, button 3, front air suction window 4, and its back side is provided with back side air and sucks window 5 and battery case 6.

Described single-chip microcomputer is that inlet end is connected with gas sensor, moisture sensor, heat sensitive sensor, clock signal, button respectively with supporting functor connected mode, and its endpiece is connected with LCD display, alarm respectively.

Described LCD display, being provided with the air quality grade at its screen interface shows, ranking score is good, general, difference shows, mouth with the anthropomorphic dummy is the grade image, the below straight line of mouth is general (promptly shown in Figure 6), difference with straight line become the bending curvature line down shown in, good with straight line become the bending curvature line up shown in.The prompting of ventilating shows, reporting to the police starts prompting, air pollution degree bar; Clock, environmental degree of comfort, humidity value, temperature value, the tidemark value.

The functor that the screen interface of described LCD display is connected with single-chip microcomputer is to connect one by one or adopt to select one and select to connect.

Although the utility model can not substitute the detection identification of legal testing agency, the data of testing oneself help offering that the litigant is whether necessary assert this approach by legal testing agency, and in time whether ventilation provides the reference frame of science.And, will be made as multiple function or employing in its technical scheme and select one and select to satisfy the required of different consumers.Its general structure design is reasonable, compact in design, and market outlook are good.

Embodiment

Embodiment is example (Fig. 6) with the LCD display mode of operation.The harmful gas kind that the utility model is monitored is extensive, comprises formaldehyde, benzene class, ammonia, inflammable gas and certain density smoke from cigarette, and the air quality of indicating on the LCD display interface not necessarily reflects the concentration of the VOC gas of certain particular type.Also it should not be installed near the kitchen range top, humidifier, the well heater or temperature, humidity change big place, in order to avoid monitoring is inaccurate.Battery case 6 is made up of three joint AA batteries and external power supply ballast resistor, if only by powered battery, can only show effective temperature and humidity reading, the Detection of Air Quality function can be under an embargo, and the leftmost symbol of air pollution degree bar will flash.

Air quality level setting: introduce above-mentioned, no longer describe.

The air pollution degree bar: represent the air pollution degree from left to right from low to high, leftmost symbol does not stop to flash, and expression Detection of Air Quality function is under an embargo.During as extraneous power supply ballast resistor on rigidly connecting, symbol can not stop to move from left to right, and expression air sampling sensor in the works.

Ventilate and point out:, the prompting of the ventilation of windowing dynamically will be arranged when the room air pollution degree reaches critical conditions.

Report to the police and start prompting: when the alarm of warning function is opened, will show this symbol on the LCD display interface, and reach the warning critical conditions that the warning startup prompting the place ahead that then can occur among Fig. 6 shows wavy symbol again.

Time set: the button 3 in pressing Fig. 1 (mark " SET " button), this key of pressing enters the clock alignment pattern, and every pressing once is provided with by left-to-right and establishes 24 hours (hour to minute, if the time is provided with numeral and can flashes this moment) altogether.

Humidity value shows: effective indication range 25～95%.

Temperature value shows: effective indication range-10～95 ℃.

Environmental degree of comfort: environmental degree of comfort is with comfortable, moist, dry three kinds of expressions, and this condition among Fig. 6 is comfortable, also is that the mouth with the anthropomorphic dummy is the expression mode, and Ying Wen abbreviation or word are example in addition: comfortable COM, moist WET, dry DRY.
