Technical field

Household air humidifiers are household appliances that can increase indoor air humidity. They are mostly used in rooms or small offices to enable people to live or work in an air environment with suitable humidity and avoid various physical discomforts caused by dry air.

There are many types of existing humidifiers, such as ultrasonic atomizing humidifiers and electric heating humidifiers. Although the ultimate purpose of all types of humidifiers is to increase the indoor air humidity, they have different advantages and disadvantages. Some humidifiers have different advantages and disadvantages. The humidification rate per unit volume is not high. Some humidifiers consume high electricity when the moisture is vaporized, and some humidifiers can produce a limited amount of humidification per unit power consumption; for example, the use of electric humidifiers also involves safety performance Ultrasonic atomization humidifier requires high water quality due to the atomization process, so it needs to use high-cost pure water for humidification. If ultrasonic atomization of tap water is used directly, the components in the water quality are relatively complicated, which will give users certain Health risks.

However, the blades of such products should be moistened, and the radial direction of the evaporating impeller is 40%. 50% is immersed below the water surface of the water storage tank. The impeller needs to rotate away from the water surface to form a water film on the surface. Due to the water level, the humidification effect is easily affected by the water level. After testing, about 50% of the blades are immersed in the water in the radial direction. The humidification effect is relatively good, but the utilization rate of the evaporation area of the blade is not high.

In order to improve the humidification efficiency of the first evaporating leaf 205, the first evaporating leaf 205 has a slight slope from the edge to the middle, and the second evaporating leaf 202 is gradually inclined from the middle to the edge. When staggered and stacked, there is a gap between the first evaporating leaf 205 and the second evaporating leaf 202; during operation, the gas passes through the first evaporating leaf 205 and the second evaporating leaf 202 from bottom to top, so that the air passes through the evaporating device At 2 o'clock, the air flow path is more tortuous, so that the contact area between air and water is larger, and the air washing effect is better. The distance between the first evaporating leaf 205 and the second evaporating leaf 202 is preferably 5 to 10 mm. Increasing the moisture content of the moisture can also directly stack more first evaporating leaves 205 and second evaporating leaves 202 in the vertical direction without increasing the floor area.

Example 7:

Based on the above embodiment, another embodiment of the invention is that the evaporation device 2 is an air filter element, and the air filter element has a cylindrical shape for filtering the air entering the inner cavity of the housing 1 from the air inlet 102 by the air filter element. Exhaust from the inner cavity of the housing 1 through the air outlet 103;

The air filter element is a cylindrical body and is installed vertically in the housing 1. The air filled in from the air inlet 102 contacts one end of the air filter element. The dust in the air is absorbed by the air filter element, and at the same time it interacts with the air and the water on the air filter element. The membrane is in full contact, and finally moves to the air outlet 103 through another section of the air filter element, and finally the filtered and purified air is discharged from the inner cavity of the housing 1.

The air intake method of the air filter element can be dry air from both sides, or air from all around. Its main purpose is to filter the suspended hair, dust, and dander in the air, and at the same time use the water film formed on the air filter to reduce The content of soluble gas such as formaldehyde, CO, SO, SO2 in the air, and the humidified/purified air is output through the upper part of the air filter.
