Description

Toilet induction air draft and timing signalling device

Technical field

The utility model relates to a kind of ventilating fan, relates in particular to the ventilating fan that a kind of toilet is responded to air draft automatically and had the timing alarm function.

Background technique

In actual life, the toilet exists moist stench, when using the ventilating fan of hand switch control, can not carry out the air draft ventilation in real time, at this problem, thereby the indoor harmful gas ventilating fan of induction automatically occurred effectively detecting.But, use ventilating fan also bad merely to the removal effect of peculiar smell.

In addition, many busy family customs are read in the lavatory, are read newspaper, and for many office clan, the time of smoking has been deprived in allegro life, and the public place constraint that no smoking in addition makes many smokers form the custom of smoking when going to toilet.Therefore, the time of a lot of male sex stool is determined the time by cigarette combustion, and a cigarette has so just prolonged the time that goes to toilet greatly from lighting to the time that knocks out the minimum 5-10 of needs minute, has formed custom in the course of time.The time that goes to toilet is long not only unhygienic, and hemorrhoidal veins is squeezed for a long time, brings out hemorrhoid, and under the situation that the people is many in public, also can make troubles for other people.

Modern medicine study confirms that normal defecation time is advisable to be no more than 3 minutes.Squatting of short time can promote intestines peristalsis, in case overlong time will cause thrombosis, Asiatic water closet pan surpasses 3 minutes can directly cause hemorrhoidal veins varicose extravasated blood, easily causes hemorrhoid, cause superior rectal vein expansion etc., so shorten the favourable measure that the time of going to toilet is the prevention hemorrhoid.

The model utility content

The technical problems to be solved in the utility model is: a kind of exhaust fan in toilet is provided, can sends prompting when going to toilet overlong time, the overlong time influence is healthy to avoid going to toilet.

To achieve these goals, the technical solution adopted in the utility model is: induction air draft of a kind of toilet and timing signalling device, comprise shell, ventilating fan, power supply, drive motor and automatic control circuit, automatic control circuit is powered by power supply, it comprises gas-sensitive detecting circuit, humidity measuring circuit, microcontroller, control switch, the input end of microcontroller links with gas-sensitive detecting circuit and humidity measuring circuit respectively, the output terminal of microcontroller connects with control switch, the other end of control switch connects with drive motor, is fixed with ozonizer on the described shell, timing unit, the phonetic warning unit; Ozonizer connects with the output terminal of control switch; Comprise also being loaded on the wall of urinal rear portion or the infrared sensing switch on the left and right wall that infrared sensing switch is electrically connected with positive source, its distance of reaction comprises infrared emission, receiving circuit smaller or equal to 50cm; The timing unit input end is electrically connected with the infrared sensing switch output terminal, and it comprises timer, comparator, output judgment signal when the time, accumulative total surpassed setting value; Phonetic warning unit input end is electrically connected with the timing unit output terminal, and the other end is electrically connected with power cathode, and it comprises sound chip and Audio Frequency Amplifier, and it pronounces according to judgment signal.

The beneficial effect that the utility model brings is: on the shell of ventilating fan ozonizer is housed, has the function of the useful composition of the multiple air of sterilization, sterilization, deodorizing and increase, be convenient to keep with fresh air, clean; Also be provided with the infrared induction signalling device in addition, when going to toilet overlong time, this warning device can send prompt tone, with the chronic disease of avoiding going to toilet for a long time and causing, goes to toilet the time thereby shorten, and can reach diseases such as prevention hemorrhoid, helps healthy.

Fig. 2 is the skeleton diagram of infrared induction module of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, 2, the utility model comprises shell, ventilating fan, power supply, drive motor, also comprise the automatic control circuit and the ozonizer that are fixed on the shell, automatic control circuit comprises gas-sensitive detecting circuit, humidity measuring circuit, microcontroller MCU, control switch, and the input end of microcontroller MCU links with gas-sensitive detecting circuit and humidity measuring circuit respectively; Described gas-sensitive detecting circuit is provided with comparator, potentiometer and air-sensitive detect probe QM, the output terminal of air-sensitive detect probe QM connects with the input end of comparator, the output terminal of comparator connects with the input port of microcontroller MCU, and potentiometer is connected in the inverting input of comparator; Described humidity measuring circuit is provided with humidity transducer RH and absolute value conversion circuit, the output terminal of humidity transducer RH connects with the input end of first order comparator in the absolute value conversion circuit, the output terminal of absolute value conversion circuit connects with microcontroller MCU input, and described humidity transducer RH is preferably chip nanometer humistor; The output terminal of described microcontroller MCU connects with control switch, and the other end of control switch connects with drive motor M, ozonizer, and described microcontroller MCU is single-chip microcomputer or transport and placing device, is preferably single-chip microcomputer SN8P1602B.When air-sensitive detect probe QM induction outer signals, promptly produce a signal, after microcontroller MCU receives signal from air-sensitive detect probe QM, the output control signal is given ventilating fan, ozonizer, when the indoor air peculiar smell exceeds parameter area, ozonizer is opened, ventilate simultaneously, ozone can be material nontoxic, odorless with its oxidation Decomposition with the generation chemical reactions such as sulphide that cause stink, thereby reach the effect of deodorizing, when peculiar smell concentration was lower than setting value, circuit was then turned off ventilating fan automatically.
