Background technique

At present, there are many types of humidifiers on the market. According to the principle of humidification, they can be divided into two categories: ultrasonic humidifiers and electric heating humidifiers, among which ultrasonic humidifiers are more common.

However, the most suitable humidity required by the human body changes with the temperature and humidity of the external environment, and ordinary humidifiers on the market do not have the function of automatically adjusting the humidification amount according to the surrounding environmental conditions such as temperature and humidity; When the temperature and humidity change, the humidifier cannot automatically provide a humidification condition that is most suitable for human comfort, for example, a satisfactory humidification effect cannot be achieved; in addition. The audience of the humidifier is mostly office workers, and their range of activities can basically be considered as being in front of the desk. Ideally, it should be a small local humidifier that can humidify the area in front of the desk. However, the humidifiers in the current market are all for humidifying the entire room, which wastes a lot of electric energy and water resources, so the purpose of both high efficiency and energy saving cannot be achieved.

Utility model content

The principle, structure and specific implementation of the present utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1 and Figure 2, the self-regulating intelligent ultrasonic humidifier provided by the utility model includes an ultrasonic generator 7, a humidifier shell 3, a water tank 1, a spout 2, a temperature and humidity sensor 8 and a control unit, the control unit includes A single-chip microcomputer 9 containing a calculation program, a triode group 5 and a parallel resistor 6; the temperature and humidity sensor 8 is connected to the input end of the single-chip microcomputer through a data line, and the I/O port of the single-chip computer is connected to the base of the triode group 5; one end of the parallel resistor It is connected with the emitter of the triode group, and the other end is connected with the ultrasonic generator 7. The base of the triode is connected to the I/O port of the microcontroller to control the on and off of the triode, and the collector and emitter of the triode are connected to the circuit, which is equivalent to a controllable switch. The temperature and humidity sensor continuously monitors the temperature and humidity from the environment, which is real-time. The power of the ultrasonic generator controls the humidity of the environment, and the power is controlled by the resistance value of the parallel resistor in the control unit.

Figure 3 is a schematic diagram of the structure of the spout. There are spiral guide vanes inside the spout. The purpose is to make the outlet spray swirl, so as to reduce the diffusion speed and diffusion area of the spray, and realize the humidification function of the local area, so as to achieve both high efficiency and high efficiency.

Figure 4 is a flow chart of the calculation program of the single-chip microcomputer. When the humidifier is powered on, the temperature and humidity sensor will input the detected temperature and humidity signal of the current environment into the single-chip microcomputer, and the single-chip microcomputer calculates the optimal humidity required by the human body at this time according to the human body comfort function, and judges the current humidity. Whether the humidity is in line with human comfort, the formula of human comfort function is as follows: (ssd)=(1.818t+18.18)*(0.88+0.002f)+(t-32)/(45-t)-3.2v+18.2

Among them: t is the temperature; f is the humidity; v=0, is the wind speed in the room.

If the ambient humidity has met the humidity range corresponding to the human comfort function, all I/O ports of the microcontroller output 0 level, all branch transistors are in the off state, the ultrasonic generator does not work, and the humidifier does not humidify the environment; if the ambient humidity If the human body comfort function is not satisfied, the single-chip computer calculates the humidity required by the environment according to the human body comfort function, and obtains the resistance value required by the circuit, so as to obtain the number of triodes that need to be opened in the circuit, and the I/O port of the single-chip microcomputer outputs a high level, so that some triodes In the open state, the resistance value of the parallel resistor changes, and the humidifier works in the required power state.
