[0039] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification and in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0041] 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 cross-sectional schematic diagram of the humidifying fan of this embodiment.

[0042] like Figure 1 and Figure 2 As shown, a humidifying fan comprises: a fan housing 1, a fan assembly 2, an atomizing chamber 5 and an atomizing generator 4. An air duct 17 is provided in the fan housing 1, and a fan air inlet 15 and a fan air outlet 16 connected to the air duct 17 are provided on the fan housing 1; the fan assembly 2 is arranged in the fan housing 1; the atomizing chamber 5 is connected to the fan housing 1; the atomizing generator 4 is connected to the atomizing chamber 5; an atomizing air outlet 14 is provided on the fan housing 1, and a closed space 181c is provided in the fan housing 1, and the closed space 181c is connected to the atomizing air outlet 14 and the atomizing chamber 5.

[0043] In this embodiment, the fan assembly 2 can be (not limited to): a two-phase motor or a three-phase motor. In terms of motor structure, the fan assembly 2 can be (not limited to): an inner rotor motor or an outer rotor motor. In terms of the structure of the fan blades, the fan assembly 2 can be (not limited to): an axial flow fan or a diagonal flow fan. In the specific application process, the required fan assembly 2 can be selected according to the needs of the specific application scenario, which is not limited here.

[0044] 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 atomizer generators 4 can be selected for use.

[0045] The enclosed space 181c in this embodiment does not mean that the space is completely closed and not connected to the outside, but means that the enclosed space 181c does not have a channel or opening for the atomized water vapor to diffuse into the inside of the humidifying fan. Therefore, in some embodiments, the enclosed space 181c is interconnected with the atomizing air inlet 13 arranged in the air duct 17. In the working state, the atomizing air inlet 13 is in a pressurized state and is a channel for the air flow to flow into the enclosed space 181c. The atomized water vapor cannot diffuse from the channel to the inside of the fan. Therefore, even if the enclosed space 181c has a channel connected to the inside of the fan in this application scenario, it still belongs to the enclosed space 181c referred to in this embodiment.

[0046] In this embodiment, the enclosed space 181c is a sandwich space formed inside the fan housing 1. However, the structure of the enclosed space 181c is not limited thereto. According to different specific application scenarios, in some embodiments, the enclosed space 181c is (but not limited to): a pipe or hose disposed in the fan housing 1.

[0047] In the above embodiment, a closed space 181c is provided inside the fan housing 1, and the closed space 181c is connected to the atomizing chamber 5 and the atomizing air outlet 14, so as to prevent the atomized water vapor from flowing freely inside the humidifying fan, reduce the probability of the atomized water vapor contacting the electronic components and metal parts inside the humidifying fan, improve the safety of the humidifying fan, and extend the service life of the humidifying fan. At the same time, the closed space 181c also has the function of accommodating the atomized water vapor. When the humidifying fan is started or shut down, the air output of the humidifying fan is small or no air is output, and the atomized water vapor generated by the atomizing generator 4 cannot be blown out in time. These atomized water vapors diffuse freely in the external space, increase the humidity in the environment near the humidifying fan, and further affect the normal use of the humidifying fan, and even affect the safety of the humidifying fan in the long run. The containment function of the enclosed space 181c will greatly reduce the probability of the atomized water vapor diffusing to the outside during the above process. The atomized water vapor that is not blown out in time will gather into non-floating liquid water in the enclosed space 181c, reducing its impact on the humidity of the environment around the humidification fan and further improving the safety of the humidification fan.

[0048] See also Figure 4 , Figure 4 It is a schematic diagram of the exploded view of the humidifying fan of this embodiment.

[0049] like Figure 4 As shown, in some embodiments, a partition plate 184 is disposed in the fan housing 1, and the partition plate 184 and the fan housing 1 are enclosed to form a closed space 181c. In this embodiment, the closed space 181c is a sandwich space formed between the fan housing 1 and the partition plate 184.

[0050] The enclosed space 181c formed by dividing the fan housing 1 by the partition plate 184 has a larger space area and can accommodate more atomized water vapor. At the same time, the larger enclosed space 181c has more connecting positions with the fan outlet 16, so that the humidifying fan can be provided with more atomizing outlets 14.

[0051] In some embodiments, the atomizing air outlet 14 is disposed around the outside of the fan air outlet 16 .

[0052] However, the arrangement of the atomizing air outlet 14 is not limited thereto. Depending on the specific application scenario, in some embodiments, when the connecting bracket 11 is arranged at the center of the fan housing 1, the connecting bracket 11 is connected to the fan housing 1 through the air guide plate 12, and the atomizing air outlet 14 can also be arranged on the connecting bracket 11. In this case, the atomizing air outlet 14 is located on the inner side of the fan air outlet 16, and the atomizing chamber 5 is connected to the connecting bracket 11 through a conduit or a connecting channel. In this embodiment, the partition plate 184 is arranged in the connecting bracket 11, and the connecting bracket 11 is also a component of the fan housing 1.

[0053] In some embodiments, an air-increasing ring is disposed on the periphery of the fan housing 1, and the atomizing air outlet 14 can be opened on the air-increasing ring. In this case, the enclosed space 181c is formed inside the air-increasing ring, and the air-increasing ring is connected to the atomizing chamber 5 via a channel or a hose. In this embodiment, the air-increasing ring is a component of the fan housing 1, and the channel or hose connecting the enclosed space 181c and the atomizing chamber 5 is an extension of the enclosed space 181c.

[0054] 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 according to different specific application scenarios, the structure of the atomizing air outlet 14 can be (but not limited to): a circular, polygonal, elliptical, heart-shaped or other shaped hole.

[0055] The number of the atomization air outlets 14 in this embodiment can be (but not limited to): 1, 2, 3, 4, 5 or more.

[0056] There are multiple connecting positions between the atomizing air outlet 14 and the enclosed space 181c. The atomizing air outlet 14 is distributed around the circumference of the fan air outlet 16, so that the airflow flowing out of each fan air outlet 16 can be mixed with the atomized water vapor flowing out of the atomizing air outlet 14 at the corresponding position. Compared with the traditional point atomization, more fan airflow can be mixed with atomized water vapor, so that the mixing effect of the blown airflow is better and more uniform, which greatly improves the cooling effect of the humidification fan.

[0057] There are multiple connecting positions between the atomizing air outlet 14 and the enclosed space 181c, which increases the outlet area of ​​the atomized water vapor and enables the humidifying fan to blow out more atomized water vapor. At the same time, due to the large number of connecting positions, the diffusion speed is increased, the concentration of the atomized water vapor in the atomizing chamber 5 and the enclosed space 181c is reduced, and the probability of the atomized water vapor aggregating into liquid water is reduced, and the atomization effect of the humidifying fan is better.

[0058] In some embodiments, the humidifying fan further includes a water tank 3 , which is connected to the fan housing 1 .

[0059] The water tank 3 refers to a container for holding liquid water or fragrance liquid. In order to facilitate the addition of the above liquid into the water tank 3, the water tank 3 and the fan housing 1 are connected in a detachable manner, and the detachable connection method includes (but is not limited to): screw connection, snap connection or magnetic coupling connection. However, the connection method between the water tank 3 and the fan housing 1 is not limited to this. In some embodiments, the water tank 3 can be fixedly connected to the fan housing 1, and a water inlet is opened on the water tank 3 or the water tank 3 is designed to be an openable and closable structure.

[0060] The atomizing chamber 5 is disposed between the fan housing 1 and the water tank 3 or in the fan housing 1, and one end of the atomizing generator 4 is disposed in the water tank 3, and the other end of the atomizing generator 4 is disposed in the atomizing chamber 5. However, the location of the atomizing chamber 5 is not limited thereto, and in some embodiments, the atomizing chamber 5 can be disposed outside the fan housing 1 or outside the water tank 3 according to different specific application scenarios, and the atomizing chamber 5 is connected to the enclosed space 181c through a pipe or a hose.

[0061] The water tank 3 is connected to the shell, making the structure of the humidifying fan more compact.

[0062] See also Figure 4 and Figure 5 , Figure 4 is a cross-sectional view of the combination of the front housing and the partition plate of this embodiment; Figure 5 It is a schematic diagram of the three-dimensional structure of the front shell of this embodiment.

[0063] like Figure 4 and Figure 5 As shown, in some embodiments, the fan housing 1 includes: a front housing 181 and a rear housing 182, the front housing 181 and the rear housing 182 are connected, the fan outlet 16 and the atomization outlet 14 are both opened on the front housing 181, the fan assembly 2 is connected to the front housing 181, the partition plate 184 is arranged in the front housing 181, and the partition plate 184 and the front housing 181 are enclosed to form an enclosed space 181c.

[0064] The front shell 181 and the rear shell 182 are connected by screws. However, the connection method between the front shell 181 and the rear shell 182 is not limited to this. According to different specific application scenarios, the connection method between the front shell 181 and the rear shell 182 can be (but not limited to): snap connection, welding, screw connection, adhesive connection or integrated molding. When the front shell 181 and the rear shell 182 are integrally molded, the front shell 181 and the rear shell 182 are only used to partition the shell position function, and there is no obvious difference between the two in appearance and connection relationship.

[0065] In some embodiments, the front shell 181 and the rear shell 182 are connected via a partition plate 184 , and the partition plate 184 is connected to the front shell 181 by snapping, and then connected to the rear shell 182 by screws.

[0066] In some embodiments, the rear shell 182 and the partition plate 184 enclose a control compartment 6 , in which a PCB circuit board 61 is disposed. The control compartment 6 is independent of the enclosed space 181 c .

[0067] A control compartment 6 is constructed between the rear shell 182 and the partition plate 184 , and a PCB circuit board 61 is arranged in the control compartment 6 . Due to the arrangement of the partition plate 184 , the control compartment 6 can be kept independent and dry, thus preventing the PCB circuit board 61 from being corroded by atomized water vapor.

[0068] In some embodiments, a first air duct shell 181a is disposed in the front shell 181, an annular hole 184a is opened on the partition plate 184, the annular hole 184a is sleeved on the first air duct shell 181a, and the enclosed space 181c is disposed around the first air duct shell 181a.

[0069] The setting of the first air duct housing 181a makes the air duct 17 and the enclosed space 181c independent of each other, which can effectively prevent the atomized water vapor from entering the air duct 17 from the enclosed space 181c, causing interference and erosion to the fan assembly 2, thereby ensuring the safety and rotation efficiency of the fan assembly 2. At the same time, the enclosed space 181c is arranged around the first air duct housing 181a, so that the atomizing air outlet 14 can be arranged around the fan air outlet 16, increasing the air outlet area of ​​the atomizing air outlet 14, and can also effectively improve the uniformity of the mixed flow between the atomized water vapor and the blown air flow of the humidifying fan.

[0070] In some embodiments, a second air duct housing 182a is disposed in the rear housing 182, and the first air duct housing 181a and the second air duct housing 182a are connected to each other.

[0071] The first air duct housing 181a and the second air duct housing 182a are in contact with each other. However, the connection relationship between the first air duct housing 181a and the second air duct housing 182a is not limited thereto. Depending on the specific application scenario, in some embodiments, the first air duct housing 181a and the second air duct housing 182a are connected by (but not limited to): screw connection, threaded connection, snap connection, adhesive connection, welding or one-piece molding. When the front housing 181 and the rear housing 182 are connected by one-piece molding, the first air duct housing 181a and the second air duct housing 182a can also be connected by one-piece molding technology.

[0072] In some embodiments, the cross-sectional area of ​​the first air duct housing 181a gradually increases along the air outlet direction. The structure of the first air duct makes the first air duct "trumpet-shaped" along the air outlet direction, and the position of the first air duct housing 181a facing the second air duct housing 182a is configured as a tail structure, which can prevent the airflow from flowing back and improve the air outlet efficiency.

[0073] In some embodiments, a second air duct housing 182a is disposed in the rear housing 182, and at least a portion of the structure of the second air duct housing 182a has a cross-sectional area that gradually increases in the direction opposite to the air outlet direction.

[0074] The cross-sectional area of ​​the second air duct housing 182a gradually increases in the opposite direction of the air outlet direction, and the cross-sectional area of ​​the portion facing the first air duct housing 181a is relatively small, which also has the function of preventing the airflow from flowing back and improving the air outlet efficiency. At the same time, the cross-sectional area of ​​the portion facing away from the first air duct housing 181a is relatively large, which can increase the area and airflow of the airflow flowing into the air duct and improve the blowing efficiency of the humidifying fan.

[0075] In some embodiments, the front shell 181 and the partition plate 184 extend along the direction of the water tank 3 to form a first vertical plate 181b and a second vertical plate 184b, respectively. The first vertical plate 181b and the second vertical plate 184b are respectively inserted into the water tank 3.

[0076] The first vertical plate 181b and the second vertical plate 184b are inserted into the water tank 3, which can guide the liquid water formed in the atomization chamber 5 or the enclosed space 181c into the water tank 3, effectively avoiding the accumulation of liquid water formed by the accumulation of water vapor in the atomization chamber 5 or the enclosed space 181c, which may cause the humidification fan to leak liquid or the atomization generator 4 to be submerged and unable to work, thereby improving the stability of the humidification fan.

[0077] In some embodiments, there is a gap between the first vertical plate 181b and the second vertical plate 184b, and the gap is configured as a liquefaction channel 51. The first vertical plate 181b and the second vertical plate 184b form the liquefaction channel 51, so that the liquefied water flow flows within the range defined by the liquefaction channel 51, thereby improving the collection capacity of the liquefied water flow.

[0078] In some embodiments, the distance between the first vertical plate 181b and the second vertical plate 184b and the water tank bottom surface 31 of the water tank 3 is smaller than the distance between the atomization generator 4 and the water tank bottom surface 31 .

[0079] The distance between the atomizer 4 and the bottom surface 31 of the water tank is the lowest water level that the humidifying fan can absorb liquid. When the water level is lower than the lowest water level, the atomizer 4 will be out of contact with the liquid surface. When the air pressure in the atomizing chamber 5 or the enclosed space 181c is high, the atomized water vapor or external air will enter the water tank 3 through the liquefaction channel 51. When the distance between the first vertical plate 181b and the second vertical plate 184b and the bottom surface 31 of the water tank 3 is less than the distance between the atomizer 4 and the bottom surface 31 of the water tank, the distance between the free end of the liquefaction channel 51 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 that the atomizer can absorb, the free end of the liquefaction channel 51 is still inserted into the liquid surface, and the liquefied water vapor or external air cannot enter the water tank 3 through the liquefaction channel 51, thereby avoiding the above-mentioned problems, making the air pressure and liquid level in the water tank 3 stable, and improving the efficiency of blowing out the atomized water vapor.

[0080] In some embodiments, the atomizing chamber 5 is disposed between the partition plate 184 and the front housing 181, and the atomizing chamber 5 is located on the annular path of the enclosed space 181c. The atomizing chamber 5 is disposed between the partition plate 184 and the front housing 181, shortening the distance between the atomizing chamber 5 and the enclosed space 181c, reducing the flow distance of the atomized water vapor, and improving the blowing efficiency of the atomized water vapor.

[0081] In some embodiments, the humidifying fan further includes: a flow channel plate 184c, an atomizing air inlet 13 is opened in the front shell 181, the flow channel plate 184c is connected to the partition plate 184 to form an air flow channel, and the air flow channel connects the atomizing air inlet 13 and the atomizing chamber 5 respectively.

[0082] After the atomizer generator 4 generates atomized water vapor in the atomizer chamber 5, the fan assembly 2 pushes the airflow to flow in the air duct 17 of the fan housing 1, and part of the airflow flows into the atomizer chamber 5 through the atomizer air inlet 13 to push the airflow in the atomizer chamber 5 to flow toward the atomizer air outlet 14. The airflow flowing out of the atomizer air outlet 14 mixes with the airflow in the air duct 17 and is blown out from the fan outlet. After the airflow flowing in through the atomizer air inlet 13 pressurizes the atomized water vapor in the atomizer chamber 5 and the enclosed space 181c, the atomized water vapor has a higher initial energy after being blown out, and the mixing uniformity and mixing efficiency with the airflow blown out of the fan outlet 16 are higher.

[0083] In some embodiments, the fan housing 1 further includes: an air inlet housing 183 , the air inlet housing 183 is connected to the rear housing 182 , and a filter 185 is disposed between the air inlet housing 183 and the rear housing 182 .

[0084] The air inlet housing 183 is provided to prevent the fan assembly 2 from being exposed, thereby protecting the fan assembly 2. Meanwhile, a filter 185 is provided between the air inlet housing 183 and the rear housing 182, and the filter 185 can prevent external objects from extending into the fan housing 1, thereby protecting the fan assembly 2 as well as the human body or external objects.

[0085] In some embodiments, the fan housing 1 further includes: an air inlet housing 183 , the air inlet housing 183 is connected to the rear housing 182 , the fan air inlet 15 is opened on the air inlet housing 183 , and a filter ring 186 is provided in the air inlet housing 183 at a position corresponding to the fan air inlet 15 .

[0086] The filter ring 186 can filter the airflow entering the fan housing 1, remove particulate matter or other harmful substances contained in the airflow, and make the airflow blown out by the humidification fan fresh, which is beneficial to people's health.
