Abstract

The invention relates to a household safe toilet system based on ultrasonic detection and alarm prompt. The system includes an ultrasonic sensor arranged at the rear side direction of a closetool, an alarm lamp and an alarm, which are arranged the front side direction of the closetool, and an air interchanger arranged on a ceiling. The ultrasonic sensor and the air interchanger are electrically connected with an MCU respectively. Output ends of the MCU are also connected with timers which control the alarm lamp and the alarm. The system also includes an induction lamp arranged above a door. The induction lamp is electrically connected with the MCU. The system controls the air interchanger through the ultrasonic sensor so that an operation process is simplified; the ultrasonic sensor is high in detection accuracy and flexible in detection so that system reliability is improved; the air interchanger is closed through a delay power-off relay so that thorough cleaning of air in a toilet is facilitated and electrical energy is saved; and the alarm lamp and the alarm are automatically started through the timers so as to prompt a person in the toilet to pay attention to a health toilet time so as to reduce disease generation and improve use security.

Description

Domestic safety closet system based on ultrasound examination and alarm

Technical field

The present invention relates to Domestic toilet, relate in particular to the lavatory with ventilating system and safety instruction.

Background technology

At present, in the lavatory of family expenses, all with ventilating system, existing lavatory by the shortcoming that ventilating system exists is: when use by manually booting and closing, because switch is generally installed on the position of adult operation, inconvenience when child uses, and manual operation comparatively bothers; After going to toilet, general timely closing, causes the foul smell in lavatory thoroughly not get rid of.In existing Domestic toilet, lack prompting indicating device, user as adult all carrying mobile phone, newspaper etc. kill time, tend to the time of forgetting go to toilet too and to cause for a long time the generation of disease; If when the elderly or child go to toilet, owing to lacking alarm device, have that old man, child are improper to go to toilet as fallen down etc. and the potential safety hazard that cannot sue and labour in time.

Summary of the invention

The applicant is for the shortcoming of above-mentioned Domestic toilet ventilating system, study and improve, a kind of domestic safety closet system based on ultrasound examination and alarm with auto-induction opening and closing function, band prompting in limited time and safety prompt function function is provided.

The technical solution adopted in the present invention is as follows:

A kind of domestic safety closet system based on ultrasound examination and alarm, this system comprise be installed on side after toilet ultrasonic sensor, the warning lamp that is installed on toilet front side and alarm, be installed on the air interchanger on ceiling, described ultrasonic sensor and air interchanger are electrically connected with MCU respectively, the output terminal of described MCU also connects the first timer, the second timer and delay cut-off relay, warning lamp described in the first timer control, alarm described in the second timer control; The first timer, the second timer and delay cut-off relay are respectively by control panel setting control time;

This system also comprises the sense light that is installed on a top, and described sense light is electrically connected with MCU;

Described ultrasonic sensor detects ultrasound wave variable signal and starts by MCU and cut out described air interchanger, the first timer, the second timer and delay cut-off relay.

Beneficial effect of the present invention is as follows:

The present invention detects ultrasound wave variable signal Based Intelligent Control air interchanger by ultrasonic sensor, simplify the start-up operation of air interchanger, avoid conventional ventilation system to be not easy to the situation that child uses, and the accuracy in detection of ultrasonic sensor is high, it is sensitive to detect, improve the reliability of system; Within the time of setting, automatically close air interchanger by delay cut-off relay, be conducive to the thorough of air in lavatory to clean, and avoided user to forget and closed the energy loss that air interchanger brings; In the time of setting by timer, automatically start warning lamp, prompting toilet user notices that health goes to toilet the time, reduces disease and produces; By timer initiation alarm work, when having ensured that toilet user is improper and going to toilet, succoured in time, improve safety in utilization.

Embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

As shown in Figures 1 and 2, the domestic safety closet system based on ultrasound examination and alarm of the present embodiment, this system comprises and is installed on the ultrasonic sensor 2 of toilet 1 rear side, the warning lamp 9 that is installed on toilet 1 front side and alarm 10, is installed on the air interchanger 3 on ceiling, ultrasonic sensor 2 and air interchanger 3 are electrically connected with MCU7 respectively, the output terminal of MCU7 also connects the first timer 8, the second timer 11 and delay cut-off relay 12, the first timer 8 is controlled warning lamp 9, the second timers 11 and is controlled alarm 10; The first timer 8, the second timer 11 and delay cut-off relay 12 are respectively by control panel 5 setting control times;

This system also comprises the sense light 6 that is installed on door 4 tops, and sense light 6 is electrically connected with MCU7, and sense light 6 comprises acoustic control sense light, thermoinduction lamp, infrared induction lamp etc.;

Ultrasonic sensor 2 detects ultrasound wave variable signal and starts by MCU7 and cut out air interchanger 3, the first timer 8, the second timer 11 and delay cut-off relay 12.

The course of work of the present invention is as follows:

Before going to toilet, on control panel 5, set health and go to toilet the time, as to set the first timer 8 be 5～10 minutes, to set the second timer 11 be 15～20 minutes and set the delay cut-off time as 1～2 minute; While going to toilet, sense light 6 starts after signal being detected automatically; In the time that human body is seated on toilet 1, ultrasonic sensor 2 detects hyperacoustic variation, and variable signal is sent to MCU7, and MCU7 starts air interchanger 3, the first timer 8, the second timer 11 and delay cut-off relay 12; The first timer 8 and the second timer 11 start timing, and the first timer 8 reached after the time of setting, and signal is sent to MCU7, and MCU7 starts warning lamp 9 to remind toilet user; The second timer 11 reached after the time of setting, signal is sent to MCU7 and starts alarm 10, to point out the other staff outside lavatory, avoided toilet user to send security incident; After normally having gone to toilet, human body leaves toilet 1, and ultrasonic sensor 2 is delivered to MCU7 by ultrasound wave variable signal equally, and MCU7 closes air interchanger 3, the first timer 8 and the second timer 11 according to the power-off signal of delay cut-off relay 12; When people leaves behind lavatory, sense light 6 is closed automatically.

In the present invention, ultrasonic sensor 2, the first timer 8, the second timer 11, delay cut-off relay 12, MCU7 and air interchanger 3 are prior art.

More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of amendment.
