In use, there are a number of technical drawbacks. Conventional ultrasonic atomizers, which have a pronounced white fog, atomize large particles, typically consisting of water particles of 3 microns or more. After the water particles come out of the atomizer, the water particles need to be vaporized in the air, so that the real improvement of the air humidity can be achieved.

However, the common evaporative humidifier has obvious technical defects in both a hot mist mode and a cold mist mode. The hot fog type humidifier needs heating evaporation, so that the conversion efficiency is low and the energy consumption is high. Cold fog type humidifier, in order to increase liquid surface area, generally utilize cascade or similar structure increase the area of contact between water and the air to improve the efficiency of evaporation or vaporization, but this kind of mode easily produces the incrustation scale on cascade or similar structure, breeds the bacterium, can make the volume of product be restricted through the mode of increaseing area of contact simultaneously, is unfavorable for the development of product miniaturization.

In some embodiments, as shown in fig. 1, the humidification airflow channel 3 is a vaporization channel, and in order to achieve better vaporization, the air outlet 12 is provided in multiple, and the mist outlet 26 is provided in multiple, any combination, to increase the flow of atomized particles and air, and further increase the vaporization speed.

The working principle of the air humidifier in this embodiment is that the ultrasonic transduction atomizing plate vibrates to generate energy, water is atomized to form 3-10 micron-sized water particle mist beads, the surface area of liquid is increased, and the second pneumatic device 28 enables atomized particles to reach the mist outlet 26 through the inner cavity 22 and enter the humidifying airflow channel 3.

The air guided out of the air guiding-out component 31 is vaporized humidified air, and the effects of high humidity and no obvious atomized particles are met, so that the air is quickly humidified.

The air humidifier in the embodiment makes full use of each evaporated element, so that the humidification efficiency is improved best, and meanwhile, no bad effect or consumable material is generated.

Factors that generally affect evaporation are mainly temperature, humidity, liquid surface area and air flow velocity at the liquid surface. Whereas under relatively quiescent conditions, the rate of water evaporation is dependent only on the rate of molecular diffusion, and the rate of evaporation W is described by the following equation:

the above equation is called Dalton's Law and shows that the evaporation rate W is directly proportional to the saturation difference (E-E) and the molecular diffusion coefficient (A) and inversely proportional to the gas pressure (P). The difference between the saturated water vapor pressure (E) and the actual water vapor pressure (E) in the air at a certain temperature is called the saturation difference (d). I.e., d-E, which indicates the degree of saturation of the actual water vapor in the air, is often used in studies of water surface evaporation, and its magnitude indicates the evaporation capacity of water molecules, with larger d, stronger and faster.

In some embodiments, the combination of the structure and the principle is utilized, and all factors influencing evaporation are fully exerted, so that the evaporation efficiency is greatly improved.

The atomization part is utilized to increase the surface area of the liquid and accelerate the evaporation speed. Liquid is atomized into liquid particles with the diameter of 3-10 um, so that the surface area of the liquid is increased, the surface area of the atomized particles is increased by about 10000 times compared with the surface area of the liquid surface by taking the diameter of 20cm as an example according to the area of a container of a conventional humidifier and referring to the atomization amount of 700mL/H and the average particle diameter of 5um, the evaporation speed of the liquid is greatly increased, and a powerful condition is created for vaporization.

By using the high-speed air duct (the first air duct 13), the air flow speed on the liquid surface can be increased, and the evaporation speed can be increased. Meanwhile, the air pressure in the inner cavity 22 of the mist outlet 26 is reduced, so that the saturation difference of the humidification air flow channel 3 is increased, and the vaporization efficiency and the evaporation speed in the humidification air flow channel 3 are increased.

The heating device 14 increases the temperature in the first air duct 13, so that the temperature in the humidified air flow passage 3 is increased, the evaporation speed in the humidified air flow passage 3 is increased, the mist guided out from the mist outlet 26 is sufficiently vaporized in the humidified air flow passage 3 and the air guiding member 31, and the air flow guided out through the air guiding member 31 is humidified air without obvious atomized particles, and the humidified air can be rapidly diffused and humidified in the air.

Meanwhile, the humidified air flow path 3 is provided with the air guide-out member 31, so that the atomized particles can be fully vaporized in the path, and the purpose that the final air has enough humidity but does not contain excessive water particles is achieved.

In another aspect, a humidification method of an air humidifier, as shown in fig. 2, includes:

step1 atomizer 27 atomizes the water in water tank 24 to produce a mist. The surface area of the liquid is increased, and the evaporation speed is accelerated.

Step2 the first pneumatic means 11 generates a high velocity air stream into the humidified flow path 3. The air flow speed on the liquid surface can be increased, and the evaporation speed is increased.

Step3 the second pneumatic means 28 directs the mist into the humidified flow path 3 where it is collected with the high velocity air stream and vaporised into a gas. The gathered air flow generates a venturi effect due to the air pressure difference between the air outlet 12 and the mist outlet 26, that is, a certain air speed difference and air pressure difference exist between the high-speed air flow generated by the first pneumatic device 11 and the mist generated by the second pneumatic device 28, so that the air pressure at the mist outlet 26 and in the inner cavity 22 is reduced, the saturation difference is increased, the vaporization speed is increased, and the mist guided out by the mist outlet 26 is vaporized.

The vaporized gas at Step4 enters air outlet member 31 to be sufficiently vaporized, and enters air to humidify the air after being vaporized. The arrangement of the air guiding-out component 31 ensures that the gathered air flow can be evaporated and vaporized better, and the vaporization efficiency of the vaporizer is improved.

Preferably, the wind speed of the high-speed airflow generated by the first pneumatic device 11 at the wind outlet 12 is greater than the wind speed of the second pneumatic device 28 for guiding the mist out to the mist outlet 26.

Preferably, the atomizer 27 is an ultrasonic atomizer 27, which is disposed at the bottom of the water tank 24, and atomizes water by using energy generated by vibration of a transduction atomizing sheet in the ultrasonic atomizer 27. Other types of atomizers 27 are possible in other embodiments and are not limited to being provided at the bottom of the water bath 24.

Preferably, a baffle 15 is disposed at the air outlet 12 near the mist outlet 26, and the baffle 15 extends into the humidified airflow channel 3 toward the air guiding member 31, so that there is a pressure difference between the air outlet 12 and the mist outlet 26, and the vaporization efficiency is improved.

Preferably, a first air duct 13 is arranged between the first pneumatic device 11 and the air outlet 12, the first air duct 13 is provided with a heating device 14 for heating the air flow in the first air duct 13, and the evaporation speed is increased by the heating mode, so that the particle size of the humidified air entering the air is smaller, the diffusion speed is higher, and the humidity balance in the air is better.

In summary, the air humidifier of the present invention uses the atomizing humidification component 2 to atomize the water in the water tank 24 into particles, so as to increase the contact area between the water and the air and accelerate the evaporation rate, and uses the evaporative humidification component 1 to rapidly vaporize the water particles by using high-speed air flow, so that the air flow guided out by the air guide-out component 31 is humidified air, and can be rapidly diffused in the air to humidify the air. Meanwhile, the air humidifier is high in humidifying speed, the air humidity balance of the humidification is good, secondary condensation cannot occur, and the comfort of people is stronger.
