Description

A family bathroom lighting ventilation control device

technical field

The utility model relates to a lighting ventilation control device for a family bathroom, which belongs to the technical field of daily necessities.

Background technique

At present, the lighting lamps installed in the bathrooms of most families are mainly divided into manual switch lamps and voice-activated lamps. The switch of manually switching on and off the light needs to be touched directly by hand. Frequently going in and out of the bathroom is not only troublesome but also extremely unhygienic. However, the voice-activated lamp needs the user to make a sound before it can be turned on, and its response sensitivity is uneven, and its anti-interference ability is not strong. Secondly, as we all know, the bathroom is the place where mold, bacteria and harmful chemicals are most likely to breed, which will directly lead to the occurrence of diseases and affect the health of family members. In addition to poor sanitation, excessive moisture in the bathroom is an important predisposing factor. Although by installing the exhaust fan correctly and ensuring good indoor and outdoor ventilation, the indoor particulate matter, exhaust gas, and moisture can be completely discharged outside, but manual operation is required, which is a waste of time and manpower, and it is not necessarily To ensure that the bathroom is ventilated regularly. The utility model can not only automatically control the opening and closing of the lighting lamp according to the light intensity in the bathroom and whether someone enters, but also can automatically open the exhaust fan and the ultraviolet lamp regularly, so that ventilation can be performed, and sterilization and disinfection can be achieved. The effect is to ensure that the air in the bathroom is fresh.

Contents of the invention

The technical problem to be solved by the utility model is to provide a family bathroom lighting and ventilation control device, which can automatically control the opening and closing of the lighting lamp according to the light intensity and whether someone enters the family bathroom, and can also automatically turn on the exhaust regularly. Fans and ultraviolet lamps minimize the growth and spread of harmful chemicals such as bacteria and mold, thus ensuring fresh air in the bathroom.

The technical scheme of the utility model is: a family bathroom lighting and ventilation control device, including pressure sensor I1, pressure sensor II2, light sensor 3, timer 4, counter 5, lighting lamp 6, exhaust fan 7, ultraviolet lamp 8; The pressure sensor I1 and the pressure sensor II2 are installed sequentially from the outside to the inside at the place where people step on the door of the bathroom when people enter the door. The pressure sensor I1 and the pressure sensor II2 are separated by a certain distance, and the light sensor 3 is installed near the window of the bathroom. The exhaust fan 7 is installed in the bathroom close to the original air duct outlet or where odor and moisture are likely to be generated, the lighting lamp 6 and the ultraviolet lamp 8 are installed on the wall top of the bathroom, and the pressure sensor Ⅰ1 and pressure sensor Ⅱ2 are connected with the light sensor 3 , The pressure sensor Ⅰ1, the pressure sensor Ⅱ2 are connected to the counter 5, the counter 5 is connected to the lighting lamp 6, and the timer 4 is connected to the exhaust fan 7 and the ultraviolet lamp 8 respectively.

The initial state of the counter 5 is 0; the timer 4 is used to set the opening time and duration; the light sensor 3 is used to monitor the light intensity in the room, and when the light in the room is dark, the signal is transmitted to the two pressure sensors, so Pressure sensor Ⅰ1 and pressure sensor Ⅱ2 will be activated, and the whole device is powered by an external power supply.

The working process of the utility model is: as shown in Figure 2, the initial state of the counter is 0, and the light sensor 3 is used to monitor the light intensity in the room. When the light is dark, the signal is transmitted to the two pressure sensors, so the pressure Sensor Ⅰ1 and pressure sensor Ⅱ2 will be activated. At this time, if someone wants to enter the bathroom, the foot will first step on the pressure sensor Ⅰ1 set at the door, and then step on the pressure sensor Ⅱ2. The signal from the sensor I1 and the pressure sensor II2 will add one to the value of the counter. On the contrary, when the person walks out of the bathroom, the counter 5 will receive the signals from the pressure sensor II2 and the pressure sensor I1 in turn. The value of the counter 5 will be reduced by one, and when the value of the counter is not zero, the illuminating lamp will be turned on; when the value of the counter 5 is zero, the illuminating lamp 6 will be in the state of going out.

As shown in FIG. 3 , the timer 4 is used to set the opening time and duration of the exhaust fan 7 and the ultraviolet lamp 8 . Whenever the preset time is reached, the timer 4 will connect the circuit, so the exhaust fan 7 and the ultraviolet lamp 8 are turned on. When the preset opening time is not reached, the circuit is disconnected, and the exhaust fan 7 and the ultraviolet lamp 8 are in a closed state. As a result, periodic ventilation and sterilization are realized, thereby minimizing the growth and spread of harmful chemicals such as bacteria and mold, and ensuring fresh air in the bathroom.

The beneficial effects of the utility model are: the device can automatically control the opening and closing of the lighting lamp according to the light intensity in the bathroom and whether someone enters, and it can also automatically open the exhaust fan and the ultraviolet lamp on a regular basis to minimize bacteria, The growth and spread of harmful chemical substances such as mold, thereby ensuring fresh air in the bathroom, simple structure, and easy to use.
