Background technique

With the improvement of living standards, most offices are equipped with heating or central air-conditioning in the severe winter. This creates a warm and comfortable working environment for us, but it also brings many problems. Among them, the human body feels the most obvious. Change is dry. Dry air causes many hazards to workers, such as dry mouth, tight skin, and illness. A small humidifier is a household appliance that increases room humidity. It is increasingly used in office environments and can alleviate the above hazards to a certain extent.

However, most of the small humidifiers used in offices now have simple structures and single functions, which cannot meet people's needs. For example, in daily work, the humidifier is placed on the desk with a certain distance from the seat. When the user's nasal cavity feels particularly dry, the user will often move the nasal cavity closer to the mist outlet to absorb more mist , to alleviate the dryness of the nasal cavity, but the existing humidifier has a single control mode and function. When the nasal cavity is close to the mist outlet, the mist is still sprayed according to the original mist output and mode, and the mist output may be too large or If the situation is too small, it cannot fail to achieve the comfort that people want.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

Fig. 1 is a basic flow chart of the present invention. The humidifier used in the control method of the present invention includes two humidification modes: a common humidification mode and a nasal cavity humidification mode, wherein the normal humidification mode refers to normal room temperature and humidity conditions. The humidification mode adopted for indoor drying; the nasal cavity humidification mode refers to the humidification mode adopted by the humidifier according to the distance between the user's face and the fog outlet of the humidifier after the user's nasal cavity feels too dry and actively approaches the humidifier;

As shown in FIG. 2 , an embodiment of a humidifier control method provided by the present invention is shown. The humidifier control method of this embodiment includes the following steps:

In step S2, when the user's face is close to the fog outlet of the humidifier, the image sensor will collect the contour of the face. Since the contour area of the side face of ordinary people is smaller than the contour area of the front face, and as the angle of the face toward the sensor increases, the side face The ratio of the area of the face contour to the area of the frontal contour is increasing. Therefore, when 80% ≤ S _contour /S _pre ≤ 100%, it means that the user faces the mist outlet of the humidifier and may have a need to moisten the nasal cavity; , go to step S3.

Step S3: Use the position detector to obtain the distance D between the face and the mist outlet of the humidifier. When 10cm≤D≤20cm, the controller controls the humidifier to enter the nasal cavity humidification mode;

When it is detected in step S2 that the user is facing the mist outlet of the humidifier, it means that the user may have a need to moisten the nasal cavity. However, it is also possible that the user inadvertently looks at the mist outlet of the humidifier when turning the head. Therefore, it is necessary to go through step S3 In the distance judgment step, when the distance D between the user's face and the outlet of the humidifier satisfies 10cm≤D≤20cm, it means that the face is facing the fog outlet of the humidifier at this time and is very close to the fog outlet of the humidifier, so it can be determined that the user The nasal cavity needs to be moistened, therefore, the controller can control the humidifier to enter the nasal cavity humidification mode.

In addition, the position detector is an infrared human body sensor, and the step of using the position detector to obtain the distance D between the face and the fog outlet of the humidifier includes:

The nasal cavity humidification mode is: the controller adjusts the fog outlet area of the humidifier and the fan speed to adjust the mist output according to the mapping relationship between the distance D and the mist output S of the humidifier;

Wherein, the mapping relationship between the amount of fog S and the distance D is S=a*D+b, where a and b are constants.

It should be noted that the comfortable mist output S is calculated by the formula S=a*D+b, where a and b are constants, for example, S=0.025*D+0.01, the unit is ml/s, and the mist output increases with When the distance D increases, when D>20cm, stop the nasal cavity humidification mode and switch to the normal humidification mode. It can be understood that the values of parameters such as a and b in the above formula can be flexibly set according to specific situations, and do not limit the present invention.

It is a conventional technical means in this field to adjust the mist output by adjusting the area of the mist outlet of the humidifier and the speed of the fan, and no further elaboration will be made here. Those skilled in the art know that the shape of the mist can be adjusted by adjusting the area of the mist outlet. In the nasal cavity humidification mode, you can properly adjust the area of the mist outlet and increase the speed of the fan to adapt the amount of mist to achieve more comfortable purposes.

Further, after the step S3, it includes: when 10cm≤D≤20cm is not satisfied, the humidifier maintains the current dehumidification mode.

The controller can adjust the fog output according to the infrared human body temperature obtained by the infrared human body sensor. For example, when the human body temperature is too high, it means that the room is dry, and the fog output can be adjusted appropriately to increase the fog output.

Further, when the controller controls the humidifier to enter the nasal cavity humidification mode, a prompt is issued to remind the user to enter the nasal cavity humidification mode.

The prompt is one of alarm reminder, voice prompt and LED lamp prompt.
