[0002] Humidifying baseboards are widely used in household appliances, primarily employing atomizers to generate water mist, which is then diffused by airflow from a fan to achieve humidification. However, some humidifying baseboards suffer from uneven atomization and large fluctuations in mist output due to poor structural design, resulting in a poor user experience. Utility Model Content

The mist collecting hood includes a hood body and a dividing rib disposed within the hood body and extending downward. The dividing rib divides the mist collecting hood into a first cavity and a second cavity. The air duct is disposed in the second cavity. The mating surface between the mist collecting hood and the water tank and the dividing rib forms a mist collecting hood inlet. The height of the mist collecting hood inlet is h2, and the ratio of h1 to h2 is between 1:0.8 and 1:1.4.

[0007] An atomizer is located inside the water tank;

[0008] A fan is provided in the water tank, the fan has a fan outlet, and the fan outlet is connected to the air duct.

[0009] Beneficial Effects: The mist collection hood is located inside the water tank, with its opening facing downwards. The hood includes a body and downward-extending dividing ribs within it, dividing the hood into a first chamber and a second chamber. The atomizer is located inside the water tank, allowing the water mist generated by the atomizer to enter the mist collection hood immediately. The fan is located in the water tank, with its outlet connected to the air duct. Therefore, the airflow generated by the fan enters the air duct through the fan outlet, then enters the second chamber, passes through the mist collection hood inlet, and enters the first chamber, evenly dispersing the water mist generated by the atomizer. The water mist is finally blown out through the mist collection hood outlet. The height of the air duct is h1, and the height of the mist collection hood inlet is h2. The ratio of h1 to h2 is between 1:0.8 and 1:1.4, which optimizes the airflow within the mist collection hood, solving problems such as uneven atomization, large fluctuations in mist output, and high noise levels, thus improving the humidification and atomization effect and enhancing the user experience.

[0010] In one alternative implementation, the ratio of h1 to h2 is 1:1.1.

[0011] Beneficial effects: Optimizing the ratio of h1 to h2 to 1:1.1 can improve the airflow within the mist collection hood, solve problems such as uneven atomization, large fluctuations in mist output, and high noise, improve the humidification atomization effect, and enhance the user experience.

[0013] Beneficial effects: The ratio of the fan outlet area to the inlet area of ​​the mist collection hood is between 1:1.5 and 1:2, which can further optimize the gas flow in the mist collection hood, solve problems such as uneven atomization, large fluctuations in mist output, and high noise, improve the humidification atomization effect, and enhance the user experience.

[0014] In one alternative implementation, the ratio of the fan outlet area to the mist hood inlet area is 1:1.8.

[0015] Beneficial effects: The ratio of the fan outlet area to the inlet area of ​​the mist collection hood is 1:1.8, which can further optimize the gas flow in the mist collection hood, solve problems such as uneven atomization, large fluctuations in mist output, and high noise, improve the humidification atomization effect, and enhance the user experience.

[0016] In one optional embodiment, the horizontal distance between the air duct and the inlet of the mist collection hood is L, where 45 mm ≤ L ≤ 70 mm.

[0017] Beneficial effects: By setting the horizontal distance between the air duct and the inlet of the mist collection hood to between 45 mm and 70 mm, the airflow inside the mist collection hood can be further optimized, solving problems such as uneven atomization, large fluctuations in mist output, and high noise levels, thus improving the humidification and atomization effect and enhancing the user experience.

[0018] In one alternative implementation, 56 mm ≤ L ≤ 60 mm.

[0019] Beneficial effects: By setting the horizontal distance between the air duct and the mist collection hood inlet to between 56 mm and 60 mm, the airflow within the mist collection hood can be further optimized, solving problems such as uneven atomization, large fluctuations in mist output, and high noise levels, thus improving the humidification and atomization effect and enhancing the user experience.

[0020] In one alternative embodiment, the fan speed range is 1000-2000 rpm.

[0021] Beneficial effects: The fan speed range is 1000-2000rpm, which can ensure that the airflow maximizes the diffusion of the water mist generated by the atomizer.

[0023] Beneficial effects: The atomizer is an ultrasonic atomizer with an output frequency of 1.7MHz. The output frequency of the atomizer is coordinated with the fan speed, which can reduce noise and achieve continuous spray, thereby improving the user experience.

[0024] In one optional embodiment, the inner wall of the fog collecting hood is provided with a hydrophobic coating;

[0025] And / or, the fan is a centrifugal fan.

[0026] Beneficial effects: By applying a hydrophobic coating to the inner wall of the mist collection hood, water mist can be prevented from condensing into droplets on the inner wall of the mist collection hood. The airflow generated by the centrifugal fan enters the air duct through the fan outlet, then enters the second chamber, passes through the mist collection hood inlet, and enters the first chamber, evenly dispersing the water mist generated by the atomizer. The water mist is finally blown out through the mist collection hood outlet.

[0027] In one optional embodiment, the atomizing component further includes a water tank disposed in the water trough, and the outlet of the water tank is connected to the atomizer through the water trough.

[0028] Beneficial effect: By providing a hydrophobic coating on the inner wall of the mist collection hood, water mist can be prevented from condensing into droplets on the inner wall of the mist collection hood.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0047] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0048] Humidifying baseboards are widely used in household appliances, primarily employing atomizers to generate water mist, which is then diffused by airflow from a fan to achieve humidification. However, some humidifying baseboards suffer from uneven atomization and large fluctuations in mist output due to poor structural design, resulting in a poor user experience.

[0049] The root cause of these problems lies in the unoptimized inlet size and height parameters of the fan and the mist collection hood. Existing devices typically place the fan directly near the mist collection hood, but the ratio of the fan outlet size to the mist collection hood inlet size is mismatched, for example, a common ratio between 1:1 and 1:1.5, leading to turbulent airflow distribution. The distance between the fan and the mist collection hood is often fixed in the range of 100mm to 200mm, without considering fluid dynamics effects, which easily generates turbulence or atomized droplet condensation, reducing the uniformity of atomization diffusion.

[0050] Furthermore, the related technologies lack system parameter optimization, and the fan speed and atomizer output are not coordinated, resulting in energy waste. For example, in standard tests, the atomization efficiency is only 60%-70%, the noise level exceeds 45 decibels, and users report discontinuous spray, affecting comfort. These problems limit the application of humidifying baseboards in dry environments.

[0051] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.
