Description

Technical Field

[0001] The present application relates to the field of fans, and in particular to a humidifying fan. Background Art

[0002] In the hot summer, fans have become a must-have for people to eliminate the heat. In hot climates, in order to enhance the cooling effect of fans, people will cool down by increasing the air humidity while increasing the air flow rate. Therefore, a humidifying fan has been developed.

[0003] In the prior art, a humidifying fan generally adopts a structure in which an atomizing structure is arranged in front of the fan. When both the fan and the atomizing structure are in operation at the same time, the fan blows out air to move the atomized water vapor generated by the atomizing structure, thereby achieving the effect of atomizing blowing.

[0004] During their research, the inventors of this invention discovered that the airflow generated by conventional humidifier fans, when in operation, suppresses the atomized water vapor in front of them. This results in poor diffusion of the atomized water vapor from the humidifier fan, with only a small amount of airflow on one side of the atomizing structure being able to drive the atomizing airflow and move in conjunction with it. Airflows at other locations are unable to contact the atomized water vapor. Utility Model Content

[0022] The beneficial effects of the embodiments of the present application are as follows: the atomizing chamber of the humidifying fan is arranged between the fan housing and the water tank, and an atomizing air inlet and an atomizing air outlet connected to the atomizing chamber are respectively provided on the fan housing.

[0036] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this invention belongs. The terms used in this specification and in the description of the present invention are intended only to describe specific embodiments and are not intended to limit the present invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0037] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the humidifying fan in this embodiment; Figure 2 This is a schematic diagram of the exploded structure of the humidifying fan part of this embodiment.

[0038] like Figure 1 and Figure 2 As shown, a humidifying fan comprises: a fan housing 1, a fan assembly 2, a water tank 3, and an atomizing generator 4. An air duct 17 is defined within the fan housing 1; the fan assembly 2 is disposed within the fan housing 1; the water tank 3 is connected to the fan housing 1, forming an atomizing chamber 5 between the fan housing 1 and the water tank 3; the atomizing generator 4 is connected to the water tank 3, with one end of the atomizing generator 4 disposed within the water tank 3 and the other end of the atomizing generator 4 disposed within the atomizing chamber 5; and an atomizing air inlet 13 and an atomizing air outlet 14 are defined on the fan housing 1, with the atomizing air inlet 13 connected to the air duct 17 and the atomizing chamber 5, respectively, and the atomizing air outlet 14 connected to the air duct 17 and the atomizing chamber 5, respectively.

[0039] An air duct 17 is provided within the fan housing 1. Air duct 17 refers to the space within the housing through which air flows, extending from the fan inlet 15 to the fan outlet 16. However, the structure of air duct 17 is not limited thereto. In some embodiments, air duct 17 refers to the space within the fan housing 1 through which air flows from the time the air enters the fan housing 1 until the air completely exits the fan housing 1.

[0040] Water tank 3 is a container for holding liquid water or fragrance liquid. To facilitate the addition of the aforementioned liquid to water tank 3, water tank 3 and fan housing 1 are detachably connected. Such detachable connection methods include (but are not limited to): threaded connection, snap connection, or magnetic coupling connection. However, the connection method between water tank 3 and fan housing 1 is not limited to this. In some embodiments, water tank 3 can be fixedly connected to fan housing 1, and a water inlet can be provided on water tank 3, or water tank 3 can be designed to be openable and closable.

[0041] The atomizer 4 in this embodiment includes (but is not limited to): an ultrasonic atomizer, a vibration atomizer, or a spray humidifier. Depending on the specific application scenario, different types of atomizers 4 can be selected for use.

[0042] In the above embodiment, the atomizing chamber 5 of the humidifying fan is arranged between the fan housing 1 and the water tank 3, and the fan housing 1 is provided with an atomizing air inlet 13 and an atomizing air outlet 14 connected to the atomizing chamber 5. After the atomizing generator 4 generates atomized water vapor in the atomizing chamber 5, the fan assembly 2 pushes the air flow to flow in the air duct 17 of the fan housing 1. Part of the air flow will flow into the atomizing chamber 5 through the atomizing air inlet 13, pushing the air flow in the atomizing chamber 5 to flow toward the atomizing air outlet 14. The air flow flowing out of the atomizing air outlet 14 will mix with the air flow in the air duct 17 and then be blown out from the air outlet of the fan. When the atomized water vapor flows out of the air duct 17 of the humidifying fan using this solution, it will mix with the air flow in the air duct 17. The atomized water vapor after mixing moves with the blown air flow, has better diffusivity, and has a better cooling effect. At the same time, since the flow rate of the air flow in the air duct 17 is relatively large relative to the air flow in the atomizing chamber 5, suction is generated at the atomizing air outlet 14, and the atomized water vapor is drawn out of the atomizing chamber 5, thereby increasing the outflow efficiency of the atomized water vapor and further improving the cooling effect.

[0043] See also Figure 3 , Figure 3 Schematic cross-section of the humidifying fan of this embodiment.

[0044] like Figure 3 As shown, in some embodiments, the distance between the atomizing air inlet 13 and the fan assembly 2 is smaller than the distance between the atomizing air outlet 14 and the fan assembly 2 .

[0045] The distance between the atomizing air inlet 13 and the fan assembly 2 is less than the distance between the atomizing air outlet 14 and the fan assembly 2, that is, along the direction of the air flow in the air duct 17, the atomizing air inlet 13 is located in front of the atomizing air outlet 14. When the air flow in the air duct 17 flows, the air flow flows from the atomizing air inlet 13 into the atomizing chamber 5, and then flows from the atomizing chamber 5 to the atomizing air outlet 14. The setting of this position makes the positions of the atomizing air inlet 13 and the atomizing air outlet 14 conform to the existing rules of air flow in the air duct 17, enhances the driving effect of the air flow on the atomizer, and makes the efficiency of the atomized water vapor derived from the atomizing chamber 5 higher. At the same time, because the fan blades push the air flow during rotation, the direction of the air flow can be decomposed into a lateral momentum perpendicular to the inner wall of the fan housing 1 and a horizontal momentum along the direction of the air duct 17. The lateral momentum will be gradually offset during the air flow process, and the air flow with larger lateral momentum is more likely to enter the atomizing air inlet 13 set on the inner wall of the fan housing 1. Therefore, setting the atomizing air inlet 13 at a position closer to the fan assembly 2 can make the air intake efficiency of the atomizing air inlet 13 higher, thereby making the atomized water vapor in the atomizing chamber 5 blown out with better effect.

[0046] In some embodiments, the distance between the atomizing air inlet 13 and the fan assembly 2 is greater than or equal to the distance between the atomizing air outlet 14 and the fan assembly 2. This position structure can make the airflow blown out of the atomizing air outlet 14 mix in the air duct 17 for a longer distance and longer time, thereby achieving a better mixing effect between the atomized water vapor and the airflow.

[0047] See also Figure 4 and Figure 5 , Figure 4 This is a schematic structural diagram of the first perspective of the connection between the fan housing and the connecting frame of the embodiment; Figure 5 This is a structural schematic diagram from a second perspective showing the connection between a partial fan housing and a connecting frame in this embodiment.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, the atomizing air inlet 13 is protrudingly provided on the inner surface of the fan housing 1 , and the opening direction of the atomizing air inlet 13 is opposite to the flow direction of the air flow in the air duct 17 .

[0049] To further enhance the air intake efficiency of the atomizing air inlet 13, the atomizing air inlet 13 is provided as a protrusion on the inner surface of the fan housing 1, and the opening direction of the atomizing air inlet 13 is opposite to the direction of the air flow in the air duct 17. When the air flows in the air duct 17, the protruding atomizing air inlet 13 becomes an obstacle to the air flow, making it easier for the air to flow into the atomizing air inlet 13, thereby increasing the amount of air flowing into the atomizing air inlet 13 and enhancing the diffusion effect of the atomized water vapor in the atomizing chamber 5.

[0050] The arrangement of the atomizing air inlet 13 is not limited to this. Depending on the specific application scenario, in some embodiments, the atomizing air inlet 13 can be arranged to be flush with the inner surface of the fan housing 1 or recessed on the inner surface of the fan housing 1 to form the atomizing air inlet 13. This structural arrangement can reduce the airflow resistance inside the fan housing 1 and make the airflow in the air duct 17 more efficient.

[0051] In some embodiments, the atomizing air inlet 13 includes: an air inlet upper cover 131 and an air inlet lower cover 132. The air inlet upper cover 131 is concave toward the air inlet lower cover 132 to form an arc structure, and the air inlet lower cover 132 is concave toward the air inlet upper cover 131 to form an arc structure.

[0052] In this embodiment, the upper air inlet cover 131 and the lower air inlet cover 132 are positioned opposite each other. The lower air inlet cover 132 is formed by the fan housing 1 at a position corresponding to the upper air inlet cover 131. Both the upper air inlet cover 131 and the lower air inlet cover 132 are recessed toward the water tank 3 to form an arc-shaped structure. This arc-shaped structure reduces the surface wind resistance of the upper air inlet cover 131, reduces its impact on the airflow within the air duct 17, and improves the air output efficiency of the humidifier fan. The arc-shaped structure of the lower air inlet cover 132 enhances the airflow guidance effect, making the airflow more efficient in flowing to the atomizing air inlet 13.

[0053] In some embodiments, part of the structure of the air inlet upper cover 131 is located above the air inlet lower cover 132 , so that the air inlet upper cover 131 and the air inlet lower cover 132 form a staggered structure in space.

[0054] The upper air inlet cover 131 covers the upper part of the lower air inlet cover 132 and forms an interlaced structure, which can make the ventilation effect of the atomizing air inlet 13 better. The airflow entering the atomizing air inlet 13 is not easy to flow back, avoiding the formation of vortices in the air duct 17 caused by the backflow of the airflow, improving the air intake efficiency of the atomizing air inlet 13, and also improving the flow efficiency of the airflow in the air duct 17.

[0055] In some embodiments, a fan air inlet 15 and a fan air outlet 16 are further provided on the fan housing 1 , and the atomizing air outlet 14 is connected to the fan air outlet 16 .

[0056] In this embodiment, the fan housing 1 is provided with a fan inlet 15 and a fan outlet 16. The fan inlet 15 is a plurality of air inlet holes formed on the sidewall of the fan housing 1. However, the structure of the fan inlet 15 is not limited thereto. Depending on the specific application scenario, in some embodiments, the fan inlet 15 can be configured as (but not limited to): a honeycomb-shaped air inlet hole formed on the bottom surface of the fan housing 1 or a plurality of grille structures connecting the bottom surface and the sidewall of the fan housing 1.

[0057] The fan outlet 16 is configured as a ring-shaped structure. In some embodiments, the fan assembly 2 is disposed within the fan housing 1 via a connecting frame 11, which is connected to the fan housing 1 via a plurality of surrounding air guide plates 12. The plurality of air guide plates 12 divide the fan outlet into a plurality of arc-shaped air outlets.

[0058] The atomizing air outlet 14 is connected to the fan air outlet 16. The atomized water vapor blown out of the atomizing air outlet 14 can be mixed with the air flow blown out of the air duct 17, and the probability of the fan component 2 being in contact with the atomized water vapor can be reduced, thereby protecting the fan component 2 from being corroded by water vapor and short-circuited, thereby enhancing the safety of the humidifying fan.

[0059] In some embodiments, the atomizing air inlet 13 is disposed between two adjacent air guide plates 12. Placing the atomizing air inlet 13 between two adjacent air guide plates 12 allows the atomizing air inlet 13 to only introduce the airflow flowing through the air flow channel between the adjacent air guide plates 12, thereby reducing interference with the entire air duct 17. This balances the air intake requirements of the atomizing air inlet 13 and the smoothness of the airflow in the entire air duct 17, thereby minimizing the impact of the atomizing air inlet 13 on the airflow in the air duct 17.

[0060] In some embodiments, the atomizing air outlets 14 are distributed around the circumference of the fan air outlet 16. The opening direction of the atomizing air outlet 14 is perpendicular to the direction of air flow at the location of the fan air outlet 16.

[0061] The atomizing air outlet 14 in this embodiment is configured as an arc-shaped slit. However, the structure of the atomizing air outlet 14 is not limited thereto, and depending on the specific application scenario, the structure of the atomizing air outlet 14 can be (but not limited to): a circular, polygonal, de-circular, heart-shaped, or other shaped hole.

[0062] The number of the atomizing air outlets 14 in this embodiment can be (but not limited to): 1, 2, 3, 4, 5 or more.

[0063] The atomizing air outlets 14 are distributed around the circumference of the fan outlet 16, so that the airflow flowing out of each outlet can mix with the atomized water vapor flowing out of the atomizing air outlet 14 at the corresponding position. Compared with traditional point atomization, more fan airflow can mix with the atomized water vapor, making the mixing effect of the blown airflow better and more uniform, greatly improving the cooling effect of the humidification fan.

[0064] The opening direction of the atomizing air outlet 14 is perpendicular to the direction of the airflow at the fan outlet 16. The airflow outflowing from the outlet position and the movement direction of the atomized water vapor flowing out of the atomizing air outlet 14 are mutually perpendicular. The atomized water vapor flows along its original movement direction and collides perpendicularly with the fan airflow. This collision makes the fan airflow and the atomized water vapor merge more fully, improves the mixing efficiency, and makes the airflow and atomized water vapor merge more fully.

[0065] In some embodiments, the angle between the opening direction of the atomizing air outlet 14 and the direction of the air flow at the fan air outlet 16 is an obtuse angle or an acute angle.

[0066] In some embodiments, the atomization chamber 5 and the water tank 3 are connected through a liquefaction channel 52 , one end of the liquefaction channel 52 is connected to the atomization chamber, and the other end of the liquefaction channel 52 extends into the water tank 3 .

[0067] Atomized water vapor generated within the atomizing chamber 5 can condense into liquid water due to factors such as high density and temperature differences between the inside and outside. This accumulation of liquid water can reduce the space within the atomizing chamber 5 or flood the atomizing generator 4, rendering it inoperable. The provision of a liquefaction channel 52 guides the liquid water formed within the atomizing chamber 5 into the water tank 3, effectively avoiding these adverse effects. It also replenishes the water in the water tank 3, reducing the number of times the user needs to refill the water tank 3 and improving the user experience.

[0068] In some embodiments, the atomizing bottom surface 51 of the atomizing chamber 5 is configured as an inclined surface or an arc-shaped surface, and the liquefaction channel 52 is connected to the position where the atomizing bottom surface 51 has the lowest horizontal height, so that the liquefied liquid in the atomizing chamber 5 can easily flow into the water tank 3.

[0069] By configuring the atomizing bottom surface 51 of the atomizing chamber 5 as an inclined or curved surface, the formed liquid water can be gathered at the lowest point of the inclined or curved surface, thereby achieving the function of gathering the liquid water. Connecting the liquefaction channel 52 to the lowest point of the atomizing bottom surface 51 can improve the liquid-guiding efficiency of the liquefaction channel 52, allowing the liquefied liquid in the atomizing chamber 5 to flow more easily into the water tank 3. This structure can also reduce the rate of liquid accumulation in the atomizing chamber 5.

[0070] In some embodiments, a liquid suction rod 41 is connected to the atomizer generator 4, one end of the liquid suction rod 41 is connected to the atomizer generator 4, and the other end of the liquid suction rod 41 extends into the water tank 3, and the distance between the suspended end of the liquefaction channel 52 and the bottom surface 31 of the water tank is greater than the distance between the suspended end of the liquid suction rod 41 and the bottom surface 31 of the water tank.

[0071] The absorbent stick 41 in this embodiment is a cotton swab. However, the material of the absorbent stick 41 is not limited thereto. Depending on the specific application scenario, in some embodiments, the material of the absorbent stick 41 can be (but not limited to): paper, absorbent resin, hemp and other absorbent materials.

[0072] The suspended end of the liquid-absorbing rod 41 represents the lowest water level at which the liquid-absorbing rod 41 can absorb liquid. When the water level is lower than the lowest water level, the air flow blown into the atomizing chamber 5 by the atomizing air inlet 13 will flow into the water tank 3 along the liquefaction channel 52, resulting in a series of problems such as increased air pressure in the water tank 3, swaying of the liquid level, or reduced efficiency of blowing out atomized water vapor. In order to avoid these problems, the length of the liquefaction channel 52 is increased so that the distance between the free end of the liquefaction channel 52 and the bottom of the water tank 3 is smaller. In this way, even if the atomizer 4 continues to work and causes the liquid level of the water tank 3 to reach the bottom of the liquid-absorbing rod 41 (the liquid level and the free end of the liquid-absorbing rod 41 have just separated), the free end of the liquefaction channel 52 is still inserted into the liquid level, thereby avoiding the above-mentioned problems, stabilizing the air pressure and liquid level in the water tank 3, and improving the efficiency of blowing out atomized water vapor.
