Air cleaning device for automatically controlling light opening and closing

The present invention relates to an air cleaning device, and more particularly to an air cleaning device that automatically controls the lighting to open and close.

In recent years, due to industrial development, the amount of suspended particulates in the air has increased gradually, especially in the urban air. The content of suspended particles in the air is very fine, which can penetrate the lungs and directly enter the blood vessels. The whole body is circulated, so the impact on the human body and ecology cannot be ignored. The air quality is deteriorating, which not only causes global warming, but also causes allergic diseases such as respiratory infections and skin allergies, and even increases the occurrence of cardiovascular diseases, strokes, cancer and other fatal diseases. Therefore, the air cleaner becomes an indispensable product in life.

The control panel of the existing air cleaner has a light-emitting device and a plurality of display patterns, and the light emitted by the light-emitting device can illuminate the display patterns on the panel. However, the above-mentioned illuminating device is designed such that when the power is turned on, the illuminating device on the control panel is always bright to make the display pattern bright, so when the air cleaner is used at night, the brightness of the control panel is too high, so that it is impossible to sleep well. , affecting the quality of sleep. Users also have to worry about the use of air purifiers when the indoor air is not good enough.

In view of this, the creators of this case, based on their years of research and development experience in related fields, conducted in-depth discussions on the aforementioned shortcomings, and actively sought solutions based on the above-mentioned needs, and finally completed this creation.

One of the purposes of the present invention is to provide an air cleaning device capable of automatically controlling the opening and closing of lights (ie, light-emitting elements) when the air cleaning device is used at night, so as to prevent the lights from being too bright and making people unable to sleep. .

In order to achieve the above object, the present invention provides an air cleaning device for automatically controlling light opening and closing, comprising a casing, a panel and a circuit substrate. The panel is mounted on the housing and has a light transmissive plate and an opening in the light transmissive plate. The circuit board is disposed between the panel and the housing, and includes a switch unit, a sensing unit and a plurality of light-emitting elements disposed corresponding to the light-transmitting plate. The switch unit is respectively coupled to the sensing unit and each of the light-emitting elements, and one end of the sensing unit protrudes toward the opening to detect a moving body to open and close the light-emitting elements.

The creation also has the following effects. The height of the sensing unit of the present creation is lower than or equal to the height of the transparent plate, and the user does not accidentally touch or cause damage to the sensing unit. The sensing unit exposing the opening can detect the movement or presence of the user using a simple sensor with directivity to activate or deactivate the illumination of each of the light-emitting elements. Further, when the user is located above the panel, each of the light-emitting elements automatically generates a light display for easy manipulation. After the preset time parameter is passed and the sensing unit does not detect any moving body, each illuminating element will be automatically turned off to avoid the light being too bright.
