Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of humidifiers, in particular to a mist-free humidifier with a simple mist outlet structure. BACKGROUND

[0002] The mist-free humidifier pumps water from the bottom water tank to the top of the wet curtain for sprinkling. When the wet curtain or filter core is saturated with water, the excess water will flow back to the bottom water tank, and the wet curtain will be sprinkled by the water pump in a circulating manner. However, the circulating sprinkling method is prone to accumulate dirt and bacteria in the bottom water tank, making it difficult to ensure the hygiene of the mist outlet.

[0003] Therefore, a sewage separation type mist-free humidifier is provided in patent number CN202221384964.7, which uses two separate water tanks. The first water tank serves as the main water storage tank, and the second water tank serves as the second water tank for collecting bottom backwater for circulating sprinkling. This design ensures that the water in the first water tank does not participate in the circulating sprinkling, maintaining a cleaner and more hygienic effect of the mist-free humidification.

[0004] However, during testing and use, it was found that the mist-free humidifier still has the following defects: the first water tank 20 is arranged in the top cover assembly 90, the guide air duct 91 of the top cover assembly 90 surrounds the outside of the first water tank 20, and the mist-free air with high humidity is sent out through the guide air duct 91 towards the mist outlet at the top end of the top cover assembly 20. The longer guide air duct requires a larger housing for processing, resulting in high processing costs. On the other hand, during long-term use, dirt and bacteria accumulate in the guide air duct, causing the mist-free air to be contaminated during flow. Moreover, the flow of mist-free air or water mist in the longer guide air duct also produces relatively obvious noise. SUMMARY

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a mist-free humidifier with a simple mist outlet structure.

[0006] An embodiment of the present application adopts the technical solution to solve its technical problems: a mist-free humidifier with a simple mist outlet structure, comprising: a base, a water tank assembly, a control center, a wet curtain, a fan assembly electrically connected to the control center, a lower water control assembly, and a circulating water pump assembly;

[0007] The base is provided with a water curtain chamber, a blowing chamber, and a bottom water tank.

[0016] The base is provided with a plurality of mist outlets, and the plurality of mist outlets are communicated with the air blowing chamber. The fan assembly forms a negative pressure airflow, so that external air passes through the wet curtain of the water curtain chamber to form high-humidity non-mist air rich in water vapor, is then sucked into the air blowing chamber, and is then directly sent out from the air blowing chamber to the side or the upper side of the base through the mist outlets arranged on the upper part of the base. In the present application, the overall height of the base is obviously reduced, and the water tank assembly is directly placed on the upper part of the base instead of a top cover assembly, and water mist is directly output from the side or the upper side of the base. Since a mist guiding channel is not needed, the size of the humidifier overall shell can be effectively reduced, and noise and hygiene hazards caused by the mist guiding channel are also reduced, thereby effectively improving the user experience.
