[0046] Embodiment 1

[0047] Please refer to FIG. 1 and FIG. 2, FIG. 1 is a schematic diagram of the overall structure of the humidifying fan of the present embodiment; and FIG. 2 is a schematic diagram of the cross section of the humidifying fan of the present embodiment.

[0048] As shown in FIG. 1 and FIG. 2, a humidifying fan comprises a fan housing 1, a fan assembly 2, a water tank 3, an atomization generator 4, a base 6, and a driving assembly 7. The fan housing 1 is provided with an air duct, and the fan housing 1 is provided with a fan air outlet 12. The fan assembly 2 is arranged in the air duct and connected to the fan housing 1. The water tank 3 is connected to the fan housing 1, and an atomization chamber 5 is arranged between the water tank 3 and the fan housing 1. The fan housing 1 is provided with an atomization air outlet 13, and the atomization air outlet 13 is in communication with the atomization chamber 5. One end of the atomization generator 4 is arranged in the atomization chamber 5, and the other end of the atomization generator 4 is arranged in the water tank 3. The base 6 is rotatably connected to the water tank 3. The driving assembly 7 is arranged on the water tank 3 and / or the base 6, and is used to drive the base 6 to rotate relative to the water tank 3.

[0049] In the present embodiment, the fan assembly 2 can be (but not limited to) a two-phase motor or a three-phase motor. In terms of motor structure, the fan assembly 2 can be (but 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 (but not limited to) an axial flow fan or an inclined flow fan. In specific applications, the required fan assembly 2 can be selected according to the needs of the specific application scenario, which is not limited here.

[0050] The water tank 3 refers to a container for containing liquid water or fragrance liquid. In order to facilitate the addition of the above-mentioned liquid in the water tank 3, the water tank 3 and the fan shell 1 are connected in a detachable manner. The detachable connection manner includes (but is not limited to): screw connection, clamping connection or magnetic coupling connection. However, the connection manner of the water tank 3 and the fan shell 1 is not limited thereto. In some embodiments, the water tank 3 can be fixedly connected with the fan shell 1, and a water inlet is provided on the water tank 3 or the water tank 3 is designed as an openable and closable structure.

[0051] The atomization generator 4 in the embodiment includes (but is not limited to): an ultrasonic atomizer, a vibration type atomizer or a spray type humidifier. Different types of atomization generators 4 can be selected for use according to different specific application scenarios.

[0052] The driving assembly 7 in the embodiment is arranged on the water tank 3 and / or the base 6. In some embodiments, the driving assembly 7 is a driving motor 71 arranged on the water tank 3, and a rotating shaft 711 of the driving motor 71 or a component connected with the rotating shaft 711 abuts against the base 6. In some embodiments, the driving assembly 7 is a driving motor 71 arranged on the base 6, and a rotating shaft 711 of the driving motor 71 or a component connected with the rotating shaft 711 abuts against the water tank 3.

[0053] In some embodiments, the driving assembly 7 includes two parts, which are respectively: a driving motor 71 and a path limiting mechanism cooperating with the driving motor 71, and the path limiting mechanism is engaged with a part of the rotating shaft 711 of the driving motor 71. The driving motor 71 and the path limiting mechanism are arranged respectively, and when the driving motor 71 is arranged on the water tank 3, the path limiting mechanism is arranged on the base 6; when the driving motor 71 is arranged on the base 6, the path limiting mechanism is arranged on the water tank 3.

[0054] In the above-mentioned embodiments, the atomization chamber 5 is arranged between the fan shell 1 and the water tank 3, the atomization outlet 13 of the atomization chamber 5 is arranged on the fan shell 1, the water tank 3 is rotatably connected with the base 6, and the driving assembly 7 for driving the relative rotation between the water tank 3 and the base 6 is arranged between the water tank 3 and the base 6. When the driving assembly 7 drives the water tank 3 to rotate relative to the base 6, the fan shell 1 and the atomization chamber 5 will synchronously rotate with the water tank 3. Since the fan outlet 12 and the atomization outlet 13 are both arranged on the fan shell 1, the fan outlet 12 and the atomization outlet 13 will synchronously rotate when the fan shell 1 rotates. This structure makes the relative position relationship between the fan outlet 12 and the atomization outlet 13 unchanged during rotation, so that the mixing of the airflow and the atomized water vapor is always stable, and the mixing effect is uniform. At the same time, since the water tank 3, the atomization chamber 5 and the atomization generator 4 can synchronously rotate, the position between the atomization generator 4 and the water tank 3 will not change with the rotation. In this state, the working state of the atomization generator 4 is stable, and the atomization effect is better.

[0055] In some embodiments, the driving assembly 7 comprises a driving motor 71 and a driving gear 73 connected to the driving motor 71, the driving motor 71 is arranged on the water tank 3, the base 6 is provided with a path ring 72 matched with the driving gear 73, and the driving gear 73 and the path ring 72 abut each other. In this embodiment, the path limiting mechanism is the path ring 72. The mutual cooperation between the driving gear 73 and the path ring 72 can increase the interaction force between the driving gear 73 and the path ring 72, so that the rotation of the humidifying fan is more stable. At the same time, since the path ring 72 has the functions of guiding and limiting the movement path of the driving gear 73, the rotation range of the humidifying fan can be controlled.

[0056] In some embodiments, the path limiting mechanism is (not limited to) a rack on the inner circumferential surface of the storage groove 61, a tooth mark on the surface of the base 3, etc.

[0057] In some embodiments, the atomizing air outlet 13 is arranged around the outside or inside of the fan air outlet 12.

[0058] The atomizing air outlet 13 in this embodiment is configured as an arc-shaped slot. However, the structure of the atomizing air outlet 13 is not limited to this, and according to different specific application scenarios, the structure of the atomizing air outlet 13 can be (not limited to) a circular hole, a polygonal hole, an elliptical hole, a heart-shaped hole, or a hole of other shapes.

[0059] The number of the atomizing air outlet 13 in this embodiment can be (not limited to) one, two, three, four, five, or more.

[0060] The atomizing air outlet 13 is distributed around the fan air outlet 12 in the circumferential direction, so that the airflow flowing out of each air outlet can be mixed with the atomized water vapor flowing out of the atomizing air outlet 13 at the corresponding position. Compared with the traditional point-shaped atomization, more fan airflow can be mixed with the atomized water vapor, so that the mixing effect of the blowing airflow is better and more uniform, greatly improving the cooling effect of the humidifying fan.

[0061] The atomizing air outlet 13 is arranged outside the fan air outlet 12, but the arrangement of the atomizing air outlet 13 is not limited to this. According to different specific application scenarios, in some embodiments, when the center of the fan shell 1 is provided with a connecting bracket 11, the atomizing air outlet 13 can also be arranged on the connecting bracket 11. At this time, the atomizing air outlet 13 is located inside the fan air outlet 12, and the atomizing chamber 5 is in communication with the connecting bracket 11 through a conduit or a connecting passage.

[0062] In some embodiments, the atomization chamber 5 is in communication with the air duct. After the atomization chamber 5 is in communication with the air duct, the atomization inlet 14 is formed, and the airflow in the air duct can enter the atomization chamber 5 through the atomization inlet 14 to push the atomized water vapor in the atomization chamber 5 to flow rapidly to the atomization outlet 13, thereby improving the blowing efficiency of the atomized water vapor at the atomization outlet 13, making the blown atomized water vapor have a higher initial velocity, and the mixing effect of the airflow and the atomized water vapor being more obvious.

[0063] In some embodiments, the atomization chamber 5 and the water tank 3 are in communication. The mutual communication between the atomization chamber 5 and the water tank 3 can make the liquid water in the atomization chamber 5 flow into the water tank 3, avoid the liquid water from being accumulated and flooded, protect the atomization generator 4, make the working of the atomization generator 4 stable, and make the atomized water vapor generation rate tend to be consistent. At the same time, the water tank 3 can also be supplemented with water, reduce the water supplementing frequency of the water tank 3, and prolong the use time of the humidifying fan after single water supplementing.

[0064] In some embodiments, the inner diameter surface of the path ring 72 is provided with a first rack 721, and the first rack 721 is arranged around the inner diameter surface. The drive gear 73 is in meshing engagement with the first rack 721.

[0065] Please refer to FIG. 3 and FIG. 4, FIG. 3 is a disassembled structural schematic diagram of the base of the present embodiment, and FIG. 4 is a structural schematic diagram of the path ring of the present embodiment.

[0066] As shown in FIG. 3 and FIG. 4, the first rack 721 is arranged on the inner surface of the path ring 72, and the drive gear 73 and the first rack 721 are in meshing engagement. The arrangement of the first rack 721 can increase the interaction force between the drive gear 73 and the path ring 72, make the head rotation of the humidifying fan more stable, make the rotation force stronger, and make the rotation anti-external interference performance more excellent. At the same time, since the first rack 721 has a guiding and limiting effect on the movement path of the drive gear 73, the rotation range of the humidifying fan can be controlled.

[0067] In some embodiments, the surface of the base 6 is concave to form a storage groove 61, and the path ring 72 is arranged in the storage groove 61. The path ring 72 and the storage groove 61 are in abutment with each other, and the path ring 72 rotates relative to the storage groove 61 under the action of the first external force.

[0068] The path ring 72 and the storage groove 61 are in abutment with each other, but under the action of a certain size of external force, the path ring 72 and the storage groove 61 can also rotate relative to each other. This structure can make the humidifying fan rotate along the path ring 72 in a normal state, and when the user holds and rotates it by hand, the path ring 72 can also rotate relative to the storage groove 61. The user can adjust the direction of the humidifying fan by hand, which is convenient for the user to use.

[0069] The first external force in the embodiment refers to an external force acting on the humidifying fan, which can cause the relative rotation of the storage groove 61 and the path ring 72. The specific value is determined according to the required force for the relative rotation of the storage groove 61 and the path ring 72. In specific application scenarios, the size of the first external force is different in different use environments, which is not limited here.

[0070] In some embodiments, a second gear rack 62 is arranged around the inner surface of the storage groove 61, and a plurality of limiting protrusions 722 that cooperate with the second gear rack 62 are protruded on the outer peripheral surface of the path ring 72.

[0071] In the embodiment, the second gear rack 62 can completely cover the inner peripheral surface of the storage groove 61. However, the length of the second gear rack 62 is not limited to this. According to different specific application scenarios, the second gear rack 62 can be divided into multiple segments and arranged at intervals on the inner periphery of the storage groove 61 or only cover part of the inner periphery of the storage groove 61.

[0072] The mutual engagement between the limiting protrusions 722 and the second gear rack 62 stabilizes the first external force required for the rotation between the storage groove 61 and the path ring 72. Only when the first external force can cause the relative movement between the limiting protrusions 722 and the second gear rack 62, the storage groove 61 and the path ring 72 will rotate relative to each other. This structure has strong anti-interference ability and stabilizes the required conditions for the rotation of the storage groove 61 and the path ring 72, which are not affected by accidental external forces.

[0073] In some embodiments, the water tank bottom surface 31 of the water tank 3 protrudes to form a connecting column 34 facing the base 6, the bottom of the storage groove 61 protrudes to form a connecting ring 63 facing the water tank 3, the connecting column 34 is inserted into the connecting ring 63, the connecting column 34 is provided with a connecting stop edge 35 abutting against the connecting ring 63, and the bottom of the base 6 is provided with a fixing seat 64 connected with the connecting ring 63 and abutting against the base 6.

[0074] The arrangement of the connecting ring 63 and the connecting column 34 can cause the rotation of the water tank 3 relative to the base 6. The arrangement of the connecting stop edge 35 abutting against the connecting ring 63 on the connecting column 34 can cause the gap between the water tank 3 and the base 6. The existence of the gap avoids the complete fit between the water tank 3 and the base 6, reduces the friction area between the water tank 3 and the base 6, and makes the rotation more smooth.

[0075] In some embodiments, the connecting stop edge 35 can be a bearing, wherein the inner ring of the bearing is sleeved on the connecting column 34, and the outer ring of the bearing abuts against the connecting ring 63. This structure can further reduce the rotation resistance of the water tank 3 and the base 6, making the rotation of the humidifying fan more smooth and light.

[0076] The fixed seat 64 is connected with the connecting column 34 by screwing, riveting, welding or gluing, and the fixed seat 64 and the base 6 abut each other to prevent the connecting column 34 from being separated from the connecting ring 63, so that the base 6 and the water tank 3 can rotate and connect with each other.

[0077] In some embodiments, the path ring 72 is provided with a clearance groove 726 on the side away from the second rack 62, and the limiting protrusion 722 and the path ring 72 are connected by a deformable part 725, so that the limiting protrusion 722 retreats to the clearance groove 726 under radial force.

[0078] The clearance groove 726 allows the limiting protrusion 722 to retreat to the clearance groove 726 under the extrusion of the teeth of the second rack 62, reduces the extrusion force between the limiting protrusion 722 and the second rack 62, and makes the limiting protrusion 722 separate from the currently contacted tooth, thereby realizing the rotation between the storage groove 61 and the path ring 72.

[0079] The clearance groove 726 and the deformable part 725 can reduce the interaction force between the storage groove 61 and the path ring 72 when they rotate, thereby reducing the friction force when they rotate, making the rotation more smooth and light, and reducing the friction between the storage groove 61 and the path ring 72, reducing the friction loss between the second rack 62 and the limiting protrusion 722, and prolonging the service life of the two.

[0080] In some embodiments, the limiting protrusion 722 is recessed inward on both sides to form a first limiting groove 723 and a second limiting groove 724, and the first limiting groove 723 and the limiting protrusion 722 are smoothly connected, and the second limiting groove 724 and the limiting protrusion 722 are smoothly connected.

[0081] The first limiting groove 723 and the second limiting groove 724 are arranged on both sides of the limiting protrusion 722, which can avoid the tooth of the second rack 62 from contacting the body of the path ring 72, can keep the first external force required for the rotation of the limiting protrusion 722 and the second rack 62 stable, and can also protect the outer circumferential surface of the path ring 72 from being scratched by the second rack 62. Meanwhile, the limiting protrusion 722 and the first limiting groove 723 and the second limiting groove 724 are smoothly connected, which can make the first limiting groove 723 and the second limiting groove 724 have a guiding effect, and can facilitate the rotation of the limiting protrusion 722 on the second rack 62. The arrangement of the first limiting groove 723 and the second limiting groove 724 can also make the limiting protrusion 722 more easily retreat, reduce the internal stress between the limiting protrusion 722 and the easily-deformable part 725 when the limiting protrusion 722 retreats, make the arc-shaped stress surface composed of the limiting protrusion 722 and the easily-deformable part 725 become an "S"-shaped or "Z"-shaped stress surface, greatly reduce the internal resistance required to be overcome by the limiting protrusion 722 when retreating, reduce the rotation resistance, and increase the fatigue resistance of the limiting protrusion 722 and the easily-deformable part 725.

[0082] In some embodiments, a plurality of first protruding parts 728 are formed on the upper surface of the path ring 72, and the plurality of first protruding parts 728 are spaced apart to form a first abutting part 727, which abuts against the water tank 3 or abuts against the water tank 3 after the water tank 3 is pressed.

[0083] After the first abutting part 727 abuts against the water tank 3, the user rotates the humidifying fan manually, and the friction between the first abutting part 727 and the water tank 3 drives the path ring 72 to rotate, thereby realizing manual steering adjustment of the humidifying fan. In a normal state, the first abutting part 727 and the water tank 3 are separated from each other, and when the water tank 3 is pressed by an external force, the first abutting part 727 and the water tank 3 abut against each other, thereby providing a frictional driving force for the rotation of the path ring 72.

[0084] In some embodiments, the first abutting part 727 and the water tank 3 abut against each other in a normal state, but the interaction force between the first abutting part 727 and the water tank 3 in this state is smaller than the set value of the first external force, and is insufficient to drive the path ring 72 to rotate. When the water tank 3 is pressed by an external force, the interaction force between the first abutting part 727 and the water tank 3 is greater than the first external force, thereby driving the path ring 72 to rotate.

[0085] The first protruding part 728 is a contact point protruding on the upper surface of the path ring 72. However, the structure of the first protruding part 728 is not limited thereto, and in some embodiments, the first protruding part 728 can be a ball.

[0086] The number of the first protruding part 728 can be (but is not limited to) 2, 3, 4, 5, or more.

[0087] The first abutting portion 727 increases the contact points between the water tank 3 and the path ring 72, so that the user can directly act on the path ring 72 when manually rotating the humidifying fan, without the need for transmission through the driving motor 71 and the driving gear 73. Compared with the mode of transmitting external force through the driving motor 71 and the driving gear 73, and then rotating the path ring 72 by the driving gear 73, the mode of mutual abutment between the first abutting portion 727 and the water tank 3 is more direct in force transmission, and the force required to rotate the path ring 72 is smaller, which is more convenient for the user to operate.

[0088] In some embodiments, a plurality of second protruding portions (not shown in the figure) are protruding on the lower surface of the path ring 72, and the second protruding portions are spaced around to form a second abutting portion, which abuts against the base 6.

[0089] The second protruding portion is a contact point protruding on the lower surface of the path ring 72. However, the structure of the second protruding portion is not limited thereto, and in some embodiments, the second protruding portion can be a ball bearing.

[0090] The number of second protruding portions can be (but not limited to) 2, 3, 4, 5, or more.

[0091] The second abutting portion reduces the contact area between the path ring 72 and the base 6, so that the resistance when the path ring 72 rotates is smaller, and the smoothness when the humidifying fan is manually rotated is improved.

[0092] Please refer to FIG. 5, which is a structural schematic diagram of the base of the present embodiment.

[0093] As shown in FIG. 5, in some embodiments, the bottom of the water tank 3 protrudes to form an arc-shaped abutting portion 33, which abuts against at least two first protruding portions 728 in the first abutting portion 727.

[0094] The arc-shaped abutting portion 33 thickens the contact position between the water tank 3 and the first abutting portion 727, so that the bottom of the water tank 3 and the first abutting portion can interact with each other for a long time, improve the durability of the humidifying fan, and protect the water tank 3. At the same time, the arc-shaped abutting portion 33 increases the gap between the water tank 3 and the base 6 as a whole, which can effectively avoid mutual abutment between the surface of the water tank 3 and the surface of the base 6 under the action of external force, and improve the smoothness of the humidifying rotation.

[0095] In some embodiments, the first protruding portion 728 and the second protruding portion each have a smooth surface. The smooth surface of the first protruding portion 728 and the second protruding portion can protect other components and surfaces in contact with the first protruding portion 728 and the second protruding portion, reduce the loss caused by friction scratches, and at the same time, reduce the resistance when the path ring 72 rotates relative to the base 6 or the water tank 3, so that the humidifying fan rotates more smoothly.

[0096] In some embodiments, the water tank 3 is provided with an assembly groove 32, the driving motor 71 is arranged in the assembly groove 32, and the rotating shaft 711 of the driving motor 71 is connected with the driving gear 73. The assembly groove 32 can protect the driving motor 71 and improve the stability of the assembly of the driving motor 71. The assembly groove 32 is arranged on the water tank bottom surface 31 of the water tank 3.

[0100] Embodiment 2

[0101] Please refer to FIG. 7 and FIG. 8, FIG. 7 is a structural schematic diagram of the whole humidifying fan in the embodiment; and FIG. 8 is an exploded structural schematic diagram of part of the humidifying fan in the embodiment.

[0102] As shown in FIG. 7 and FIG. 8, the humidifying fan comprises a fan shell 1, a fan assembly 2, a water tank 3, and an atomization generator 4. The fan shell 1 is provided with an air duct 17; the fan assembly 2 is arranged in the fan shell 1; the water tank 3 is connected with the fan shell 1, and the fan shell 1 and the water tank 3 form an atomization chamber 5; the atomization generator 4 is connected with the water tank 3, one end of the atomization generator 4 is arranged in the water tank 3, and the other end of the atomization generator 4 is arranged in the atomization chamber 5; the fan shell 1 is provided with an atomization air inlet 13 and an atomization air outlet 14, respectively, the atomization air inlet 13 is connected with the air duct 17 and the atomization chamber 5, respectively, and the atomization air outlet 14 is connected with the air duct 17 and the atomization chamber 5, respectively.

[0103] The fan housing 1 is provided with an air duct 17, which refers to the space formed in the housing between the fan air inlet 15 and the fan air outlet 16 for the airflow to flow. However, the structure of the air duct 17 is not limited thereto, and in some embodiments, the air duct 17 refers to the space in the fan housing 1 through which the airflow flows during the process of entering the fan housing 1 and completely leaving the fan housing 1.

[0104] The water tank 3 refers to a container for holding liquid water or fragrance liquid. To facilitate the addition of the above-mentioned liquid into the water tank 3, the water tank 3 and the fan housing 1 are connected in a detachable manner, which includes but is not limited to screwing, snap connection or magnetic coupling connection. However, the connection manner of the water tank 3 and the fan housing 1 is not limited thereto, and in some embodiments, the water tank 3 can be fixedly connected with the fan housing 1, and a water inlet is provided on the water tank 3 or the water tank 3 is designed as a structure that can be opened and closed.

[0105] The atomization generator 4 in the embodiment includes but is not limited to an ultrasonic atomizer, a vibration atomizer or a spray humidifier. Different types of atomization generators 4 can be selected for use according to different specific application scenarios.

[0106] In the above-mentioned embodiment, the atomization chamber 5 of the humidifying fan is arranged between the fan housing 1 and the water tank 3, and the fan housing 1 is respectively provided with an atomization air inlet 13 and an atomization air outlet 14 that communicate with the atomization chamber 5. When the atomization generator 4 generates atomized water vapor in the atomization chamber 5, the fan assembly 2 drives the airflow to flow in the air duct 17 of the fan housing 1, part of the airflow flows into the atomization chamber 5 through the atomization air inlet 13, and drives the airflow in the atomization chamber 5 to flow toward the atomization air outlet 14. The airflow flowing out of the atomization air outlet 14 is mixed with the airflow in the air duct 17, and then blows out from the fan air outlet. The humidifying fan using the above-mentioned scheme mixes the atomized water vapor with the airflow in the air duct 17 when the atomized water vapor flows out of the air duct 17, and the atomized water vapor moves with the blowing airflow, which has better diffusivity and better cooling effect. At the same time, since the flow rate of the airflow in the air duct 17 is relatively large compared with that of the airflow in the atomization chamber 5, an suction force is generated at the position of the atomization air outlet 14 to draw the atomized water vapor out of the atomization chamber 5, which increases the outflow efficiency of the atomized water vapor and further improves the cooling effect.

[0107] Please refer to FIG. 9, which is a cross-sectional view of the humidifying fan of the embodiment.

[0108] As shown in FIG. 9, in some embodiments, the distance between the atomization air inlet 13 and the fan assembly 2 is less than the distance between the atomization air outlet 14 and the fan assembly 2.

[0109] The distance between the atomization air inlet 13 and the fan assembly 2 is less than the distance between the atomization air outlet 14 and the fan assembly 2, that is, along the direction of the airflow flowing in the air duct 17, the atomization air inlet 13 is located in front of the atomization air outlet 14. When the airflow flows in the air duct 17, the airflow flows into the atomization chamber 5 from the atomization air inlet 13 and then flows from the atomization chamber 5 to the atomization air outlet 14. The position of the atomization air inlet 13 and the atomization air outlet 14 is set according to the airflow flowing in the air duct 17, which enhances the driving effect of the airflow on the atomizer and improves the efficiency of the atomized water vapor flowing out of the atomization chamber 5. At the same time, the fan blades push the airflow to flow during rotation, and the direction of the airflow can be decomposed into a transverse momentum perpendicular to the inner wall of the fan shell 1 and a horizontal momentum along the direction of the air duct 17. The transverse momentum is gradually offset during the airflow flowing, and the airflow with a larger transverse momentum is more likely to enter the atomization air inlet 13 arranged on the inner wall of the fan shell 1. Therefore, the atomization air inlet 13 is arranged closer to the fan assembly 2, which can improve the air inlet efficiency of the atomization air inlet 13 and further improve the blowing effect of the atomized water vapor in the atomization chamber 5.

[0110] In some embodiments, the distance between the atomization air inlet 13 and the fan assembly 2 is greater than or equal to the distance between the atomization air outlet 14 and the fan assembly 2. This position structure can make the airflow blown out by the atomization air outlet 14 flow longer and for a longer time in the air duct 17, so that the mixing effect between the atomized water vapor and the airflow is better.

[0111] Please refer to FIG. 10 and FIG. 11, FIG. 10 is a first perspective view of the connection between the fan shell and the connecting frame in this embodiment, and FIG. 11 is a second perspective view of the connection between the fan shell and the connecting frame in this embodiment.

[0112] As shown in FIG. 10 and FIG. 11, in some embodiments, the atomization air inlet 13 is protrudedly arranged on the inner surface of the fan shell 1, and the opening direction of the atomization air inlet 13 is opposite to the direction of the airflow flowing in the air duct 17.

[0113] In order to further improve the air inlet efficiency of the atomization air inlet 13, the atomization air inlet 13 is protrudedly arranged on the inner surface of the fan shell 1, and the opening direction of the atomization air inlet 13 is opposite to the direction of the airflow flowing in the air duct 17. When the airflow flows in the air duct 17, the protruded atomization air inlet 13 becomes an obstacle to the airflow, which makes the airflow more easily flow into the atomization air inlet 13, increases the airflow flowing into the atomization air inlet 13, and improves the diffusion effect of the atomized water vapor in the atomization chamber 5.

[0114] The setting mode of the atomization air inlet 13 is not limited to this. According to different specific application scenarios, in some embodiments, the atomization air inlet 13 can be arranged to be flush with the inner surface of the fan shell 1 or recessed on the inner surface of the fan shell 1 to form the atomization air inlet 13. The arrangement of this structure can reduce the air flow resistance in the fan shell 1, and the air flow in the air duct 17 has higher flow efficiency.

[0115] In some embodiments, the atomization air inlet 13 comprises an air inlet upper cover 131 and an air inlet lower cover 132. The air inlet upper cover 131 is recessed to form an arc-shaped structure facing the direction of the air inlet lower cover 132. The air inlet lower cover 132 is recessed to form an arc-shaped structure facing away from the air inlet upper cover 131.

[0116] In this embodiment, the air inlet upper cover 131 and the air inlet lower cover 132 are arranged oppositely. The air inlet lower cover 132 is formed at a position corresponding to the air inlet upper cover 131 of the fan shell 1. Both the air inlet upper cover 131 and the air inlet lower cover 132 are recessed to form arc-shaped structures facing the direction of the water tank 3. The arc-shaped structures can reduce the surface air resistance of the air inlet upper cover 131, reduce the influence of the air inlet upper cover 131 on the airflow in the air duct 17, and improve the air outlet efficiency of the humidifying fan. The air inlet lower cover 132 is configured as an arc-shaped structure, which can enhance the guiding effect on the airflow, so that the airflow flowing to the atomization air inlet 13 has higher efficiency.

[0117] 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.

[0118] The air inlet upper cover 131 covers the air inlet lower cover 132 and forms a staggered structure, which can make the atomization air inlet 13 have better air scooping effect, and the airflow entering the atomization air inlet 13 is not easy to backflow. The formation of vortex in the air duct 17 caused by airflow backflow is avoided, which improves the air inlet efficiency of the atomization air inlet 13 and also improves the flow efficiency of the airflow in the air duct 17.

[0119] In some embodiments, the fan shell 1 is further provided with a fan air inlet 15 and a fan air outlet 16. The atomization air outlet 14 is communicated with the fan air outlet 16.

[0120] In this embodiment, the fan shell 1 is provided with a fan air inlet 15 and a fan air outlet 16. The fan air inlet 15 is a plurality of air inlets arranged on the side wall of the fan shell 1. However, the structure of the fan air inlet 15 is not limited to this. According to different specific application scenarios, in some embodiments, the fan air inlet 15 can be arranged as (not limited to) a honeycomb-shaped air inlet arranged on the bottom surface of the fan shell 1 or a plurality of grid structures connecting the bottom surface and the side wall of the fan shell 1.

[0121] The fan outlet 16 is arranged in a ring structure. In some embodiments, the fan assembly 2 is arranged in the fan housing 1 through the connecting frame 11, the connecting frame 11 is connected with the fan housing 1 through a plurality of ring-arranged air deflectors 12, and the plurality of air deflectors 12 separate the fan outlet into a plurality of arc-shaped air outlets.

[0122] The atomizing outlet 14 is communicated with the fan outlet 16, the atomized water vapor blown out of the atomizing outlet 14 can be mixed with the airflow blown out of the air duct 17, and the atomized water vapor can reduce the probability of the fan assembly 2 contacting the atomized water vapor, so as to protect the fan assembly 2 from being eroded and short-circuited by the water vapor, and enhance the safety of the humidifying fan in use.

[0123] In some embodiments, the atomizing inlet 13 is arranged between two adjacent air deflectors 12. Arranging the atomizing inlet 13 between the two adjacent air deflectors 12 makes the atomizing inlet 13 only introduce the airflow in the airflow channel between the adjacent air deflectors 12, reduces the interference with the entire air duct 17, balances the air inlet demand of the atomizing inlet 13 and the smoothness of the airflow in the entire air duct 17, and maximally reduces the influence of the atomizing inlet 13 on the airflow in the air duct 17.

[0124] In some embodiments, the atomizing outlets 14 are distributed along the circumference of the fan outlet 16. The opening direction of the atomizing outlet 14 is perpendicular to the direction of the airflow at the position of the fan outlet 16.

[0125] The atomizing outlet 14 in the embodiment is configured as an arc-shaped slit. However, the structure of the atomizing outlet 14 is not limited thereto, and according to different specific application scenarios, the structure of the atomizing outlet 14 can be (but not limited to) a circular hole, a polygonal hole, a circular hole, a heart-shaped hole, or other shaped holes.

[0126] The number of the atomizing outlets 14 in the embodiment can be (but not limited to) one, two, three, four, five, or more.

[0127] Distributing the atomizing outlets 14 along the circumference of the fan outlet 16 makes the airflow at the position of each outlet be able to mix with the atomized water vapor blown out of the atomizing outlet 14 at the corresponding position. Compared with the traditional point-shaped atomization, more fan airflow can be mixed with the atomized water vapor, the mixing effect of the blown-out airflow is better and more uniform, and the cooling effect of the humidifying fan is greatly improved.

[0128] The opening direction of the atomizing air outlet 14 is perpendicular to the direction of the air flow at the position of the fan air outlet 16. The air flow at the outlet position is perpendicular to the direction of the atomized water vapor flowing out of the atomizing air outlet 14. The atomized water vapor flows along its original direction, and collides with the fan air flow perpendicularly. Such collision enables the fan air flow and the atomized water vapor to be more fully mixed, improves the mixing efficiency, and enables the fan air flow and the atomized water vapor to be more fully mixed.

[0129] In some embodiments, the angle between the opening direction of the atomizing air outlet 14 and the direction of the air flow at the position of the fan air outlet 16 is an obtuse angle or an acute angle.

[0130] In some embodiments, the atomizing chamber 5 and the water tank 3 are connected through a liquidizing channel 52. One end of the liquidizing channel 52 is connected to the atomizing chamber, and the other end of the liquidizing channel 52 extends into the water tank 3.

[0131] The atomized water vapor generated in the atomizing chamber 5 may condense into liquid water due to factors such as large density and large internal and external temperature difference. The aggregation of the liquid water reduces the space in the atomizing chamber 5, or the liquid water may submerge the atomizing generator 4 and make it unable to work. The liquidizing channel 52 can guide the liquid water formed in the atomizing chamber 5 into the water tank 3, effectively avoiding the above-mentioned adverse effects. The liquidizing channel 52 can also supplement the water in the water tank 3, reduce the frequency of the user supplementing the water in the water tank 3, and improve the user experience.

[0132] In some embodiments, the atomizing bottom surface 51 of the atomizing chamber 5 is configured as an inclined surface or an arc-shaped surface. The liquidizing channel 52 is connected at the position of the lowest horizontal level of the atomizing bottom surface 51, so that the liquidized liquid in the atomizing chamber 5 is easily flowed into the water tank 3.

[0133] The atomizing bottom surface 51 of the atomizing chamber 5 is configured as an inclined surface or an arc-shaped surface, which can converge the formed liquid water to the lowest position of the inclined surface or the arc-shaped surface, and has the function of converging the liquid water. The liquidizing channel 52 is connected at the position of the lowest horizontal level of the atomizing bottom surface 51, which can improve the liquid guiding efficiency of the liquidizing channel 52, so that the liquidized liquid in the atomizing chamber 5 is easily flowed into the water tank 3. This structure can also reduce the liquid accumulation rate in the atomizing chamber 5.

[0134] In some embodiments, the atomizing generator 4 is connected with a liquid suction rod 41. One end of the liquid suction rod 41 is connected with the atomizing generator 4, and the other end of the liquid suction rod 41 extends into the water tank 3. The distance between the free end of the liquidizing channel 52 and the water tank bottom surface 31 is greater than the distance between the free end of the liquid suction rod 41 and the water tank bottom surface 31.

[0135] The liquid absorbing stick 41 in the embodiment is a cotton stick. However, the material of the liquid absorbing stick 41 is not limited thereto, and in some embodiments, the material of the liquid absorbing stick 41 can be (but is not limited to) paper, water-absorbing resin, hemp, and other water-absorbing materials.

[0136] The lowest water level of the liquid absorbing stick 41 indicates that the liquid absorbing stick 41 can absorb liquid. When the water level is lower than the lowest water level, the airflow blown into the atomization chamber 5 from the atomization air inlet 13 will flow into the water tank 3 along the liquidization channel 52, causing a series of problems such as an increase in air pressure in the water tank 3, liquid surface fluctuation, or a decrease in the atomized water vapor blowing efficiency. In order to avoid these problems, the length of the liquidization channel 52 is increased, so that the free end of the liquidization channel 52 is closer to the bottom of the water tank 3. In this way, even if the liquid surface of the water tank 3 reaches the bottom of the liquid absorbing stick 41 (the liquid surface is just separated from the free end of the liquid absorbing stick 41) due to the continuous operation of the atomization generator 4, the free end of the liquidization channel 52 is still inserted into the liquid surface, thereby avoiding the above-mentioned problems, stabilizing the air pressure in the water tank 3, stabilizing the liquid surface, and improving the atomized water vapor blowing efficiency.

[0168] Embodiment 3

[0169] Please refer to FIG. 17 and FIG. 18, FIG. 17 is a schematic diagram of the structure of the humidifying fan of the embodiment; and FIG. 18 is a schematic diagram of the partial structure of the humidifying fan of the embodiment.

[0170] As shown in FIG. 17 and FIG. 18, a humidifying fan comprises a fan shell 1, a fan assembly 2, a fan cover 3, a water tank 4 and an atomization generator 52. The fan shell 1 is provided with an air duct; the fan assembly 2 is arranged in the fan shell 1; the fan cover 3 is arranged on the fan shell 1 and connected with the fan shell 1; the water tank 4 is connected with the fan cover 3, and the water tank 4 and / or the fan cover 3 is provided with an atomization chamber 5; the atomization generator 52 is connected with the water tank 4, one end of the atomization generator 52 is arranged in the atomization chamber 5, and the other end of the atomization generator 52 is arranged in the water tank 4; the fan cover 3 is provided with an atomization air outlet 51, the atomization air outlet 51 is communicated with the atomization chamber 5, and the atomization air outlet 51 is arranged around the fan air outlet 13 of the fan shell 1.

[0171] The fan shell 1 is provided with an air duct, which refers to the space for airflow flowing in the shell from the fan air inlet to the fan air outlet 13. However, the structure of the air duct is not limited to this, in some embodiments, the air duct refers to the space in the fan shell 1 during the process of airflow entering the fan shell 1 to completely leaving the fan shell 1.

[0172] The water tank 4 refers to a container for containing liquid water or fragrance liquid. In order to facilitate the addition of the above-mentioned liquid in the water tank 4, the water tank 4 and the fan shell 1 are connected in a detachable manner, and the detachable connection manner includes (but not limited to) screwing, clamping connection or magnetic coupling connection. However, the connection manner of the water tank 4 and the fan shell 1 is not limited to this, in some embodiments, the water tank 4 can be fixedly connected with the fan shell 1, and a water inlet is arranged on the water tank 4 or the water tank 4 is designed as an openable and closable structure.

[0173] The atomization generator 52 in the embodiment includes (but not limited to) ultrasonic atomizer, vibration atomizer or spray humidifier. According to different specific application scenarios, different types of atomization generators 52 can be selected for use.

[0174] The fan assembly 2 in the embodiment includes a fan motor and fan blades. The fan motor is a three-phase motor, which has a higher rotating speed and a larger rotating speed adjustment space, so that the humidifying fan has more adjustment gears and a stronger air supply capacity. In the embodiment, the fan motor adopts a motor structure with an outer rotor.

[0175] However, the specific type of the fan motor is not limited thereto. In some embodiments, the fan motor can be a two-phase motor, and the fan motor can adopt a structure with an inner rotor.

[0176] In the embodiment, the fan blades can be inclined-flow fan blades. However, the type of the fan blades is not limited thereto. In some embodiments, the fan blades can be axial-flow fan blades.

[0177] The humidifying fan has the atomizing chamber 5 arranged in the water tank 4 and / or the fan housing 3, the atomizing chamber 5 is provided with an atomizing generator 52, and the atomizing air outlet 51 of the atomizing chamber 5 is arranged on the fan housing 3 and surrounds the fan air outlet 13. When the airflow is blown out from the fan air outlet 13, the airflow can be mixed with the atomized water vapor in the atomizing air outlet 51. Since the atomizing air outlet 51 is arranged in a surrounding manner, the contact area between the blown-out airflow and the atomized water vapor can be increased, the mixing space between the blown-out airflow and the atomized water vapor is larger, and the mixing effect is better. Meanwhile, since the airflow blown out from the fan air outlet 13 has a faster speed, a negative pressure area is formed around the fan air outlet 13. The air pressure value in the negative pressure area is lower than the atmospheric pressure value, which can extract the atomized water vapor in the atomizing air outlet 51, accelerate the flow rate of the atomized water vapor out of the atomizing chamber 5, and make the flow rate of the atomized water vapor positively correlated with the air outlet speed of the fan. When the air outlet speed of the fan is high, the space to which the airflow is delivered is larger, and more atomized water vapor is needed. Conversely, when the air outlet speed of the fan is low, the space to which the airflow is delivered is relatively small, and the atomized water vapor needed is also correspondingly reduced. Therefore, the flow rate of the atomized water vapor positively correlates with the air outlet speed of the fan, so that the flow rate of the atomized water vapor can be consistent with the actual use demand, the cooling effect of the humidifying fan is enhanced, the adaptability of the humidifying fan to different use scenarios is improved, and the application scenarios of the humidifying fan are widened.

[0178] In some embodiments, the opening direction of the atomizing air outlet 51 is perpendicular to the direction of the airflow at the position of the fan air outlet 13.

[0179] The atomizing air outlet 51 in the embodiment is configured as an arc-shaped slit. However, the structure of the atomizing air outlet 51 is not limited thereto, and can be (but not limited to) a circular hole, a polygonal hole, a re-circular hole, a heart-shaped hole, or a hole with other shapes, according to different specific application scenarios.

[0180] The number of the atomizing air outlets 51 in the embodiment can be (but not limited to) one, two, three, four, five, or more.

[0181] The atomizing air outlet 51 is arranged between the outer cover inner shell 32 and the outer cover ring 33, and the slit structure makes the atomized water vapor relatively dispersed when being blown out, thereby reducing the interference of the atomized water vapor on the airflow blown out by the fan air outlet 13.

[0182] In some embodiments, the atomizing air outlet 51 can also be arranged in the outer cover inner shell 32, the outer cover ring 33, the outer cover outer shell 31, or between the outer cover outer shell 31 and the outer cover ring 33.

[0183] Please refer to FIG. 19 and FIG. 20, FIG. 19 is a cross-sectional view of the humidifying fan in the embodiment, and FIG. 20 is a front view of the humidifying fan in the embodiment.

[0184] As shown in FIG. 19 and FIG. 20, the atomizing air outlets 51 are arranged along the circumference of the fan air outlet 13, so that the airflow at each position of the fan air outlet 13 can be mixed with the atomized water vapor blown out by the atomizing air outlet 51 at the corresponding position. Compared with the conventional point-shaped atomization, more fan airflow can be mixed with the atomized water vapor, and the mixing effect of the blown-out airflow is better and more uniform, thereby greatly improving the cooling effect of the humidifying fan.

[0185] The opening direction of the atomizing air outlet 51 is perpendicular to the direction of the airflow at the position of the fan air outlet 13. The airflow at the position of the fan air outlet 13 and the atomized water vapor blown out by the atomizing air outlet 51 are perpendicular to each other. The atomized water vapor flows along its original direction of movement, and collides with the fan airflow perpendicularly. Such collision can make the fan airflow and the atomized water vapor more fully mixed, thereby improving the mixing efficiency and making the airflow and the atomized water vapor more fully mixed.

[0186] In some embodiments, the opening direction of the atomizing air outlet 51 is inclined to the direction of the airflow at the position of the fan air outlet 13, so that the intersection angle between the atomized water vapor blown out by the atomizing air outlet 51 and the airflow at the position of the fan air outlet 13 is an acute angle.

[0187] The opening direction of the atomization air outlet 51 is inclined to the airflow direction of the fan air outlet 13. The opening direction of the atomization air outlet 51 is inclined, so that the movement direction of the atomized water vapor from the atomization air outlet 51 is inclined to the water vapor blown by the fan air outlet 13. This structure reduces the impact of the atomized water vapor on the airflow blown by the fan air outlet 13. Because the atomized water vapor moves obliquely, its kinetic energy is decomposed into vertical kinetic energy perpendicular to the airflow of the fan air outlet 13 and horizontal kinetic energy, and the movement direction of the horizontal kinetic energy is consistent with the movement direction of the airflow blown by the fan air outlet 13. Therefore, this structure can reduce the impact of the atomized water vapor on the airflow and reduce the interference with the airflow. In this embodiment, the angle between the opening direction of the atomization air outlet 51 and the horizontal line is 0-90°.

[0188] Please refer to FIG. 23, which is a schematic diagram of the structure of the outer cover base in this embodiment.

[0189] As shown in FIG. 23, in some embodiments, the fan outer cover 3 extends in the direction facing the water tank 4 to form an outer cover base 311, which is connected with the water tank 4. The atomization chamber 5 is arranged in the outer cover base 311, and the atomization generator 52 is connected with the outer cover base 311. The outer cover base 311 is provided with a liquid leakage through hole 312 around the position of the atomization generator 52.

[0190] The atomization generator 52 is arranged at one end of the atomization chamber 5 and protrudes into the atomization chamber 5. The liquid leakage through hole 312 is arranged around the atomization generator 52. Specifically, the liquid leakage through hole 312 is in the shape of a circular arc and is arranged around the atomization generator 52. However, the shape of the liquid leakage through hole 312 is not limited to this. In some embodiments, the shape of the liquid leakage through hole 312 can be (but is not limited to) circular, polygonal, oval, or other regular shapes.

[0191] In some embodiments, in order to better guide the liquid water formed by condensation, the bottom surface of the atomization chamber 5 where the liquid leakage through hole 312 is located is designed to be inclined, so that the water flow can better condense and converge and then flow to the water tank 4.

[0192] The atomized water vapor generated in the atomization chamber 5 will condense into liquid water under the action of factors such as large density and large internal and external temperature difference. The aggregation of the liquid water will reduce the space in the atomization chamber 5, or the liquid water will submerge the atomization generator 52 and make it unable to work. The arrangement of the liquid leakage through hole 312 can guide the liquid water formed in the atomization chamber 5 to the water tank 4, effectively avoiding the occurrence of the above-mentioned adverse effects. It can also supplement the water in the water tank 4, reduce the frequency of the user supplementing the water in the water tank 4, and improve the user experience.

[0193] In some embodiments, the fan cover 3 comprises a cover inner shell 32, a cover outer shell 31 and a cover ring 33, the cover inner shell 32 is connected with the fan shell, the cover outer shell 31 is covered on the cover inner shell 32, the cover ring 33 is arranged between the cover inner shell 32 and the cover outer shell 31 and connected with the cover inner shell 32 and the cover outer shell 31 respectively, and the cover outer shell 31 extends to the water tank 4 to form a cover base 311.

[0194] By arranging the fan cover 3 independently from the fan shell, the cover inner shell 32, the cover outer shell 31 and the cover ring 33 of the fan cover 3 form a space for guiding the atomized water vapor independently, which can avoid the atomized water vapor entering the fan shell 1 to erode the electronic components in the fan shell 1 or cause short circuit, thereby further improving the safety of the atomized fan and prolonging the service life of the atomized fan.

[0195] In some embodiments, the cover base 311 is provided with an atomization partition plate 53, one end of the atomization partition plate 53 abuts against the cover inner shell 32, and the atomization partition plate 53 divides the cover shell into an atomization chamber 5 and an outdoor space 54.

[0196] The atomization partition plate 53 divides the space in the cover base 311 into the atomization chamber 5 and the outdoor space 54, so that the space in the atomization chamber 5 is reduced, the space for the atomized water vapor to diffuse is compressed, and the time for the atomized water vapor to flow to the atomization air outlet 51 is reduced. When the humidifying fan is started, the atomized water vapor can diffuse along the direction from the atomization chamber 5 to the atomization air outlet 51 only when the atomization chamber 5 is filled with atomized water vapor. In the case that the atomization space is small, the time for the atomization diffusion is shortened. Therefore, the arrangement of the atomization partition plate 53 can reduce the time for the humidifying fan to “fog” and improve the timeliness of the atomization mixed flow of the humidifying fan.

[0197] In some embodiments, the atomization partition plate 53 is arranged in the cover base 311 in an inclined manner, and the space of the atomization chamber 5 gradually decreases along the direction from the water tank 4 to the atomization air outlet 51.

[0198] The atomization partition 53 is inclined towards the direction of the atomization air outlet 51, so that the space on the horizontal section in the atomization chamber 5 gradually decreases along the direction from the water tank 4 to the atomization air outlet 51. Similarly, the inclined arrangement of the atomization partition 53 plays a role in controlling the overall space in the atomization chamber 5, further compressing the space in the atomization chamber 5, thereby reducing the time for the atomized water vapor to flow to the atomization air outlet 51 and improving the timeliness of the mixed flow of the humidifying fan. Moreover, the inclined arrangement of the atomization partition 53 gradually reduces the space for the atomized water vapor to flow out to the atomization air outlet 51, thereby gradually increasing the flow speed of the atomized water vapor, reducing the speed difference between the atomized water vapor and the outflowing air flow, making the mixing between the atomized water vapor and the outflowing air flow more uniform, and making the cooling effect of the humidifying fan more obvious.

[0199] Please refer to FIG. 22, which is a structural schematic diagram of the connecting frame in the embodiment.

[0200] As shown in FIG. 22, in some embodiments, the humidifying fan further comprises a connecting frame 6 connected with the fan shell 1 through a plurality of wind deflectors 61 arranged around, the fan assembly 2 is connected with the connecting frame 6, and a storage cover 62 is arranged on the side of the connecting frame 6 opposite to the fan assembly 2, so as to form a storage compartment 63 between the storage cover 62 and the connecting frame 6.

[0201] The fan motor in the fan assembly 2 is connected with the connecting frame 6, and the fan blades are sleeved on the fan motor. The plurality of wind deflectors 61 divide the fan air outlet 13 into a plurality of arc-shaped air outlets, and in some embodiments, each arc-shaped air outlet is provided with a corresponding atomization air outlet 51, and the arc-shaped curve length of the atomization air outlet 51 is greater than the arc length of the arc-shaped air outlet. Since the air flow blown out of the arc-shaped air outlet will quickly spread to a larger space position after leaving the constraint of the arc-shaped air outlet, and the length of the atomization air outlet 51 corresponding to the arc-shaped air outlet is greater, the contact area between the atomized air flow and the blown air flow is increased, and the mixing effect is better.

[0202] The shape of the storage cover 62 is configured as a circular arc shape. However, the shape of the storage cover 62 is not limited thereto, and according to different specific application scenarios, in some embodiments, the shape of the storage cover 62 can be (but not limited to) an elliptical shape, a polygonal shape or other regular shapes.

[0203] In some embodiments, a battery assembly 7 is arranged in the storage compartment 63, a battery support 64 is arranged in the storage compartment 63, a buffer 71 is arranged on the battery assembly 7, and the buffer 71 is wrapped at the contact position between the battery assembly 7 and the battery support 64, so that at least part of the structure of the battery assembly 7 is exposed.

[0204] The battery support 64 is provided in the storage compartment 63 and includes support plates arranged alternately in horizontal and vertical directions, and battery notches are provided on the support plates and have shapes matching those of the battery assembly 7 to clamp the battery.

[0205] To better protect the battery and reduce the influence of external force on the stability and safety of the battery, the battery assembly 7 is provided with a buffer 71 made of, but not limited to, foam, fabric, paper sheet or other materials having a buffering effect.

[0206] The buffer 71 is wrapped around the contact position of the battery assembly 7 and the battery support 64. When the humidifying fan is shaken or collided, the force acting on the battery assembly 7 needs to be conducted through the battery support 64, and the buffer 71 wrapped around the contact position of the battery assembly 7 and the battery support 64 can provide maximum protection for the battery. At the non-contact position of the battery support 64 and the battery assembly 7, the opportunity of being impacted and acted by external force is very limited, and exposing this position will not only not reduce the safety protection of the battery, but also better dissipate heat from the battery due to the exposed position, thereby improving the heat dissipation capacity of the battery assembly 7.

[0207] In some embodiments, the battery assembly 7 can be arranged in the outdoor space 54.

[0208] In some embodiments, to increase the battery capacity of the humidifying fan, two groups of battery assemblies 7 are arranged in the outdoor space 54 and the storage compartment 63, respectively.

[0209] In some embodiments, when two groups of battery assemblies 7 are arranged, the power supply can be supplied in a separate manner, in which one group of battery assemblies 7 supplies power to the fan assembly 2, and the other group of battery assemblies 7 supplies power to the rotating rudder, the lighting device arranged in the humidifying fan or other power-consuming devices. However, the power supply mode of the two groups of battery assemblies 7 is not limited to this, and according to different specific application scenarios, in some embodiments, the two groups of batteries can be connected in series or parallel and supplied together.

[0210] In some embodiments, the fan cover 3 and the fan housing 1 are provided with an air increasing gap 34, and the air increasing gap 34 is located at the first end 14 of the fan housing 1, and the gap spacing at the first end 14 is greater than the gap spacing at the second end 15 of the fan housing 1.

[0211] The fan assembly 2 rotates to push the air flow entering the fan housing 1 to the fan outlet 13, and the air flow has initial kinetic energy after flowing out of the fan outlet 13. The air flow with the initial kinetic energy can drive other air flows in contact with it to flow. The air flow flowing out of the fan outlet 13 can drive the air flow at the position of the fan cover 3 at the outlet to move, thereby forming a negative pressure wind area in front of the fan cover 3. Under the action of atmospheric pressure, the air flow behind the fan cover 3 flows into the wind increasing gap 34 and forms a stable directional flow. The air flow flowing out of the wind increasing gap 34 is driven by the air flow flowing out of the fan outlet 13 to flow, thereby increasing the wind power of the humidifying fan, increasing the air outlet amount of the humidifying fan, and improving the air outlet efficiency of the humidifying fan.

[0212] The first end 14 of the wind increasing gap 34 is an end opposite to the fan outlet 13, and the second end 15 is an end opposite to the first end. The gap distance of the wind increasing gap 34 at the first end 14 of the fan housing 1 is greater than the gap distance of the fan housing 1 at the second end 15. The flow space of the air flow in the wind increasing gap 34 gradually decreases when the air flow flows, thereby achieving the effect of increasing the pressure of the air flow in the wind increasing gap 34, and making the initial speed of the air flow flowing out of the wind increasing gap 34 higher.

[0213] Please refer to FIG. 21, which is a schematic diagram of the connection structure of the outer shell and the air guide shell of the fan cover according to the embodiment.

[0214] As shown in FIG. 21, in some embodiments, the fan housing 1 comprises an air inlet shell 12 and an air guide shell 11. The air inlet shell 12 is connected with the air guide shell 11, and the air guide shell 11 is connected with the fan cover 3. The inner diameter of the air guide shell 11 gradually increases along the air outlet direction.

[0215] The fan outlet 13 is arranged on the air guide shell 11. The air guide shell 11 and the air inlet shell 12 are connected by clamping and / or screw connection.

[0216] The fan inlet is arranged on the air inlet shell 12, which can be (but not limited to) an air inlet hole arranged on the surface of the fan housing 1, a grid-shaped air inlet arranged on the bottom of the air inlet shell 12, an air inlet of an air inlet shell, etc.

[0217] The filter ring 121 is arranged in the air inlet shell 12 and is configured in a pleated structure.

[0218] The inner diameter of the air guide shell 11 gradually increases along the air outlet direction. The horn-shaped structure of the air guide shell can reduce the backflow of the fan assembly 2 and improve the air outlet efficiency of the humidifying fan.

[0219] Embodiment 4

[0220] Please refer to Fig. 24 and Fig. 25, Fig. 24 is a schematic diagram of the overall structure of the humidifying fan of the embodiment; Fig. 25 is a schematic diagram of the cross section of the humidifying fan of the embodiment.

[0221] As shown in Fig. 24 and Fig. 25, a humidifying fan comprises a fan shell 1, a fan assembly 2, an atomization chamber 5 and an atomization generator 4. The fan shell 1 is provided with an air duct 17, and the fan shell 1 is provided with a fan air inlet 15 and a fan air outlet 16 which communicate with the air duct 17; the fan assembly 2 is arranged in the fan shell 1; the atomization chamber 5 is connected with the fan shell 1; the atomization generator 4 is connected with the atomization chamber 5; the fan shell 1 is provided with an atomization air outlet 14, and the fan shell 1 is provided with a closed space 181c which communicates with the atomization air outlet 14 and the atomization chamber 5.

[0222] In the embodiment, the fan assembly 2 can be (but not limited to) a two-phase motor or a three-phase motor. In terms of motor structure, the fan assembly 2 can be (but 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 (but not limited to) an axial fan or an inclined flow fan. In the specific application process, the required fan assembly 2 can be selected according to the needs of the specific application scene, which is not limited here.

[0223] The atomization generator 4 in the embodiment comprises (but not limited to) an ultrasonic atomizer, a vibration atomizer or a spray humidifier. Different types of atomization generators 4 can be selected for use according to different specific application scenarios.

[0224] The closed space 181c in the embodiment does not mean that the space is completely closed and does not communicate with the outside, but means that the closed space 181c does not have a passage or opening for the atomized water vapor to diffuse into the interior of the humidifying fan. Therefore, in some embodiments, the closed space 181c communicates with the atomization air inlet 13 arranged in the air duct 17, and in the working state, the atomization air inlet 13 is in a pressurized state and is a passage for airflow to flow into the closed space 181c, and the atomized water vapor cannot diffuse from the passage into the interior of the fan. Therefore, even if the closed space 181c has a passage communicating with the interior of the fan in this application scenario, it still belongs to the closed space 181c as referred to in the embodiment.

[0225] The closed space 181c in the embodiment is a sandwiched space formed in the interior of the fan shell 1. However, the structure of the closed space 181c is not limited to this, and in some embodiments, the closed space 181c is (but not limited to) a pipe or a hose arranged in the fan shell 1 according to different specific application scenarios.

[0226] In the above embodiments, the closed space 181c is formed in the interior of the fan housing 1, and the atomization chamber 5 and the atomization air outlet 14 are communicated by the closed space 181c, so that the atomized water vapor can not flow randomly in the interior of the humidifying fan, the probability of the atomized water vapor contacting the electronic components and metal parts in the interior of the humidifying fan is reduced, the safety of the humidifying fan is improved, and the service life of the humidifying fan is prolonged. Meanwhile, the closed space 181c also has the function of containing atomized water vapor. When the humidifying fan is started or turned off, the air volume of the humidifying fan is small or no air is blown out, and the atomized water vapor generated by the atomization generator 4 cannot be blown out in time. These atomized water vapors randomly diffuse in the external space, increase the humidity in the environment near the humidifying fan, and then affect the normal use of the humidifying fan, and even affect the safety of the humidifying fan for a long time. The containing function of the closed space 181c can greatly reduce the probability of the atomized water vapor diffusing to the outside in the above process. The atomized water vapor that is not blown out in time will gather into liquid water that cannot float in the closed space 181c, reduce the influence of the atomized water vapor on the humidity of the environment around the humidifying fan, and further improve the safety of the humidifying fan.

[0227] Please refer to FIG. 26, which is an exploded schematic view of the humidifying fan of the present embodiment.

[0228] As shown in FIG. 26, in some embodiments, the fan housing 1 is provided with a partition plate 184, and the partition plate 184 and the fan housing 1 form a closed space 181c. In the present embodiment, the closed space 181c is a sandwiched space formed between the fan housing 1 and the partition plate 184.

[0229] The closed space 181c formed by the partition plate 184 separating the interior of the fan housing 1 has a larger space area and can contain more atomized water vapor. Meanwhile, the larger closed space 181c has more communication positions with the fan air outlet 16, so that the humidifying fan can be provided with more atomization air outlets 14.

[0230] In some embodiments, the atomization air outlet 14 is arranged around the outside of the fan air outlet 16.

[0231] However, the arrangement of the atomization air outlet 14 is not limited to this. According to different specific application scenarios, in some embodiments, when the center of the fan housing 1 is provided with a connecting bracket 11, the connecting bracket 11 is connected with the fan housing 1 through the air guide plate 12, and the atomization air outlet 14 can also be formed on the connecting bracket 11. At this time, the atomization air outlet 14 is located on the inside of the fan air outlet 16, and the atomization chamber 5 is communicated with the connecting bracket 11 through a pipe or a connecting channel. In the present 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.

[0232] In some embodiments, the fan housing 1 is provided with a wind increasing ring, and the atomized air outlet 14 is arranged on the wind increasing ring. At this time, the closed space 181c is formed inside the wind increasing ring, and the wind increasing ring is connected with the atomizing chamber 5 through a channel or a hose. In the embodiment, the wind increasing ring is a component of the fan housing 1, and the channel or the hose connecting the closed space 181c and the atomizing chamber 5 is an extension of the closed space 181c.

[0233] The atomized air outlet 14 in the embodiment is configured as an arc-shaped slit. However, the structure of the atomized air outlet 14 is not limited thereto, and according to different specific application scenarios, the structure of the atomized air outlet 14 can be (but not limited to) a circular hole, a polygonal hole, an elliptical hole, a heart-shaped hole or other shaped hole.

[0234] The number of the atomized air outlet 14 in the embodiment can be (but not limited to) one, two, three, four, five or more.

[0235] The atomized air outlet 14 and the closed space 181c have multiple communication positions. The atomized air outlet 14 is distributed along 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 atomized air outlet 14 at the corresponding position. Compared with the traditional point-shaped atomization, more fan airflow can be mixed with the atomized water vapor, so that the mixing effect of the blowing airflow is better and more uniform, and the cooling effect of the humidifying fan is greatly improved.

[0236] The atomized air outlet 14 and the closed space 181c have multiple communication positions, which increases the outlet area of the atomized water vapor, so that the humidifying fan can blow out more atomized water vapor. At the same time, due to the large number of communication positions, the diffusion speed is improved, the concentration of the atomized water vapor in the atomizing chamber 5 and the closed space 181c is reduced, the probability of the atomized water vapor aggregating into liquid water is reduced, and the atomization effect of the humidifying fan is better.

[0237] In some embodiments, the humidifying fan further comprises a water tank 3, and the water tank 3 is connected with the fan housing 1.

[0238] The water tank 3 refers to a container for containing liquid water or fragrance liquid. In order to facilitate the addition of the above-mentioned liquid in the water tank 3, the water tank 3 and the fan housing 1 are connected in a detachable manner. The detachable connection mode includes (but not limited to) screw connection, clamping connection or magnetic coupling connection. However, the connection mode of the water tank 3 and the fan housing 1 is not limited thereto. In some embodiments, the water tank 3 can be fixedly connected with the fan housing 1, and a water inlet is arranged on the water tank 3 or the water tank 3 is designed as a structure that can be opened and closed.

[0239] The atomization chamber 5 is arranged between the fan housing 1 and the water tank 3 or in the fan housing 1, and one end of the atomization generator 4 is arranged in the water tank 3 and the other end of the atomization generator 4 is arranged in the atomization chamber 5. However, the arrangement position of the atomization chamber 5 is not limited thereto, and in some embodiments, the atomization chamber 5 can be arranged outside the fan housing 1 or outside the water tank 3, and the atomization chamber 5 is connected with the closed space 181c through a pipe or a hose.

[0240] The water tank 3 is connected with the housing, so that the structure of the humidifying fan is more compact and small.

[0241] Please refer to FIG. 27 and FIG. 28, FIG. 27 is a combined sectional view of the front housing and the partition plate of the present embodiment, and FIG. 28 is a perspective structural schematic view of the front housing of the present embodiment.

[0242] As shown in FIG. 27 and FIG. 28, in some embodiments, the fan housing 1 comprises a front housing 181 and a rear housing 182, the front housing 181 and the rear housing 182 are connected, the fan air outlet 16 and the atomization air outlet 14 are both arranged on the front housing 181, the fan assembly 2 is connected with the front housing 181, and the partition plate 184 is arranged in the front housing 181, and the partition plate 184 and the front housing 181 form a closed space 181c.

[0243] The front housing 181 and the rear housing 182 are connected through screws. However, the connection mode of the front housing 181 and the rear housing 182 is not limited thereto, and according to different specific application scenarios, the connection mode of the front housing 181 and the rear housing 182 can be (but not limited to) clamping, welding, screwing, adhesive connection or one-piece forming. When the front housing 181 and the rear housing 182 are one-piece formed, the front housing 181 and the rear housing 182 only divide the position function of the housing, and there is no obvious difference between the two in appearance and connection relationship.

[0244] In some embodiments, the front housing 181 and the rear housing 182 are connected through the partition plate 184, the partition plate 184 is connected with the front housing 181 through clamping, and then connected with the rear housing 182 through screws.

[0245] In some embodiments, the rear housing 182 and the partition plate 184 form a control compartment 6, the PCB circuit board 61 is arranged in the control compartment 6, and the control compartment 6 is independent of the closed space 181c.

[0246] The rear housing 182 and the partition plate 184 form the control compartment 6, and the PCB circuit board 61 is arranged in the control compartment 6. Since the partition plate 184 is arranged, the control compartment 6 can be kept independent and dry, and the atomization water vapor is prevented from eroding the PCB circuit board 61.

[0247] In some embodiments, the front shell 181 is provided with a first air duct shell 181a, and the partition plate 184 is provided with an annular hole 184a, which is sleeved on the first air duct shell 181a, and the closed space 181c is arranged around the first air duct shell 181a.

[0248] The first air duct shell 181a is arranged to separate the air duct 17 and the closed space 181c from each other, which can effectively prevent the atomized water vapor from entering the air duct 17 from the closed space 181c to interfere with and erode the fan assembly 2, thereby ensuring the safety and rotation efficiency of the fan assembly 2. Meanwhile, the closed space 181c is arranged around the first air duct shell 181a, which can arrange the atomized air outlet 14 around the fan air outlet 16, increase the air outlet area of the atomized air outlet 14, and effectively improve the uniformity of the mixing flow between the atomized water vapor and the blowing airflow of the humidifying fan.

[0249] In some embodiments, the rear shell 182 is provided with a second air duct shell 182a, and the first air duct shell 181a and the second air duct shell 182a are connected to each other.

[0250] The first air duct shell 181a and the second air duct shell 182a abut each other. However, the connection relationship between the first air duct shell 181a and the second air duct shell 182a is not limited thereto. In some embodiments, the first air duct shell 181a and the second air duct shell 182a are connected by means of (not limited to) screw connection, screwing, clamping, adhesive connection, welding or one-piece molding. When the front shell 181 and the rear shell 182 are connected by one-piece molding, the first air duct shell 181a and the second air duct shell 182a can also be connected by one-piece molding technology.

[0251] In some embodiments, the cross-sectional area of the first air duct shell 181a gradually increases along the air outlet direction. The structure of the first air duct makes the first air duct present a “horn shape” along the air outlet direction, and the position of the first air duct shell 181a facing the second air duct shell 182a is configured as a tail structure, which can avoid backflow of the airflow and improve the air outlet efficiency.

[0252] In some embodiments, the rear shell 182 is provided with a second air duct shell 182a, and at least part of the structure of the second air duct shell 182a gradually increases in cross-sectional area along the opposite direction of the air outlet direction.

[0253] The second air duct shell 182a has a gradually increasing cross-sectional area along the reverse direction of the air outlet direction. The portion of the second air duct shell 182a facing the first air duct shell 181a has a smaller cross-sectional area, which can prevent backflow of the airflow and improve the air outlet efficiency. Meanwhile, the portion of the second air duct shell 182a facing away from the first air duct shell 181a has a larger cross-sectional area, which can increase the area and flow rate of the airflow flowing into the air duct, thereby improving the air blowing efficiency of the humidifying fan.

[0254] In some embodiments, the front shell 181 and the partition plate 184 respectively extend along the water tank 3 to form a first vertical plate 181b and a second vertical plate 184b, which are respectively inserted into the water tank 3.

[0255] 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 sealed space 181c into the water tank 3, effectively avoiding the accumulation of liquid water formed by the water vapor in the atomization chamber 5 or the sealed space 181c, thereby preventing the humidifying fan from leaking liquid or the atomization generator 4 from being submerged and unable to work, and improving the stability of the humidifying fan.

[0256] In some embodiments, the first vertical plate 181b and the second vertical plate 184b have a gap therebetween, which is configured as a liquidization channel 51. The first vertical plate 181b and the second vertical plate 184b constitute the liquidization channel 51, so that the liquidized water flows within the range defined by the liquidization channel 51, thereby improving the collection capacity of the liquidized water.

[0257] 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 less than the distance between the atomization generator 4 and the water tank bottom surface 31.

[0258] The distance between the atomization generator 4 and the water tank bottom surface 31 is the lowest water level at which the humidifying fan can absorb liquid. When the water level is lower than the lowest water level, the contact between the atomization generator 4 and the liquid surface will be disconnected. When the air pressure in the atomization chamber 5 or the sealed space 181c is high, the atomized water vapor or external air will enter the water tank 3 through the liquidization channel 51. When 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 less than the distance between the atomization generator 4 and the water tank bottom surface 31, the free end of the liquidization channel 51 is closer to the bottom of the water tank 3. Even if the water level in the water tank 3 reaches the lowest part that the atomizer can absorb due to the continuous operation of the atomization generator 4, the free end of the liquidization channel 51 is still inserted into the liquid surface. The atomized water vapor or external air cannot enter the water tank 3 through the liquidization channel 51, thereby avoiding the above problems, stabilizing the air pressure and liquid level in the water tank 3, and improving the atomized water vapor blowing efficiency.

[0259] In some embodiments, the atomization chamber 5 is arranged between the partition plate 184 and the front shell 181, and the atomization chamber 5 is located on the annular path of the closed space 181c. The atomization chamber 5 is arranged between the partition plate 184 and the front shell 181, which shortens the distance between the atomization chamber 5 and the closed space 181c, reduces the flow distance of the atomized water vapor, and improves the blowing efficiency of the atomized water vapor.

[0260] In some embodiments, the humidifying fan further comprises a flow channel plate 184c, the front shell 181 is provided with an atomization air inlet 13, and the flow channel plate 184c is connected with the partition plate 184 to form an air flow channel, which is in communication with the atomization air inlet 13 and the atomization chamber 5 respectively.

[0261] When the atomization generator 4 generates atomized water vapor in the atomization chamber 5, the fan assembly 2 drives the air flow to flow in the air duct 17 of the fan shell 1, part of the air flow flows into the atomization chamber 5 through the atomization air inlet 13, and drives the air flow in the atomization chamber 5 to flow to the atomization air outlet 14. The air flow flowing out of the atomization air outlet 14 is mixed with the air flow in the air duct 17, and then blown out of the fan air outlet. After the air flow flowing in through the atomization air inlet 13 pressurizes the atomized water vapor in the atomization chamber 5 and the closed space 181c, the atomized water vapor is blown out with higher initial energy, and the mixing uniformity and mixing efficiency of the air flow blown out of the fan air outlet 16 are higher.

[0262] In some embodiments, the fan shell 1 further comprises an air inlet shell 183, the air inlet shell 183 is connected with the rear shell 182, and a filter screen 185 is arranged between the air inlet shell 183 and the rear shell 182.

[0263] The air inlet shell 183 is arranged to avoid exposing the fan assembly 2, which protects the fan assembly 2. Meanwhile, the filter screen 185 is arranged between the air inlet shell 183 and the rear shell 182, which can prevent external objects from extending into the fan shell 1, thereby protecting the fan assembly 2 and the human body or external objects.

[0264] In some embodiments, the fan shell 1 further comprises an air inlet shell 183, the air inlet shell 183 is connected with the rear shell 182, the fan air inlet 15 is arranged on the air inlet shell 183, and a filter ring 186 is arranged in the air inlet shell 183 at a position corresponding to the fan air inlet 15.

[0265] The filter ring 186 can filter the air flow entering the fan shell 1, and remove particulate matter or other harmful substances contained in the air flow, so that the air flow blown out of the humidifying fan is fresh, which is beneficial to people's health.

[0266] Example 5

[0267] Please refer to Fig. 29 and Fig. 30, Fig. 29 is a schematic diagram of the overall structure of the humidifying fan of the embodiment; Fig. 30 is a schematic diagram of the exploded structure of part of the humidifying fan of the embodiment.

[0268] As shown in Fig. 29 and Fig. 30, a humidifying fan, comprising: a fan shell 1, a fan assembly 2, an atomization chamber 5, an atomization generator 4 and a water tank 3. A wind channel 14 is formed in the fan shell 1, and a fan air inlet 11 and a fan air outlet 12 are formed on the fan shell 1 and communicate with the wind channel 14; the fan assembly 2 is arranged in the fan shell 1; the atomization chamber 5 is connected with the fan shell 1; the atomization generator 4 is connected with the atomization chamber 5; the water tank 3 is connected with the fan shell 1; the fan shell 1 is provided with an atomization air outlet 13, which communicates with the atomization chamber 5, and the atomization chamber 5 and the water tank 3 are communicated to make the liquid water in the atomization chamber 5 flow to the water tank 3.

[0269] In the above embodiment, the atomization chamber 5 is communicated with the water tank 3, when the liquid water in the atomization chamber 5 accumulates, the water flow can be communicated from the atomization chamber 5 to the water tank 3, so that the liquid water in the atomization chamber 5 always remains in a safe state that does not interfere with the normal operation of the atomization generator 4. This structure design can guarantee the working efficiency of the atomization generator 4 and avoid damage to the atomization generator. At the same time, the liquid water in the atomization chamber 5 is introduced into the water tank 3, which can also supplement the water in the water tank 3, reduce the frequency of users supplementing water to the water tank 3, not only convenient for users, but also save water, make the humidifying fan more water-saving and environmentally friendly.

[0270] In the embodiment, the fan assembly 2 can be (not limited to): a two-phase motor or a three-phase motor. From the motor structure, the fan assembly 2 can be (not limited to): an inner rotor motor or an outer rotor motor. From the structure of the fan blade, the fan assembly 2 can be (not limited to): an axial fan or an inclined flow fan. In the specific application process, the required fan assembly 2 can be selected according to the needs of the specific application scene, which is not limited here.

[0271] The atomization generator 4 in the embodiment includes (not limited to): an ultrasonic atomizer, a vibration atomizer or a spray humidifier. Different types of atomization generators 4 can be selected for use according to different specific application scenarios.

[0272] The water tank 3 refers to a container for containing liquid water or fragrance liquid. In order to facilitate the addition of the above-mentioned liquid in the water tank 3, the water tank 3 and the fan shell 1 are connected by a detachable manner, and the detachable connection manner includes (not limited to): screwing, clamping connection or magnetic attraction coupling connection. However, the connection manner of the water tank 3 and the fan shell 1 is not limited to this, in some embodiments, the water tank 3 can be fixedly connected with the fan shell 1, and a water inlet is formed on the water tank 3 or the water tank 3 is designed as an openable and closable structure.

[0273] In this embodiment, the atomization chamber 5 can be an independent atomization space arranged separately from the fan housing 1, or can be an auxiliary space formed by partitioning in the fan housing 1. Therefore, the connection relationship between the atomization chamber 5 and the fan housing 1 can be that the atomization chamber 5 is connected to the fan housing 1 by screwing, welding, adhesive connection, clamping, magnetic connection, riveting, etc., or can be a space connection relationship formed in the fan housing 1.

[0274] The communication relationship between the atomization chamber 5 and the water tank 3 is different according to the different relative spatial relationship between the atomization chamber 5 and the water tank 3. When the atomization chamber 5 is located above the water tank 3, the communication mode between the atomization chamber 5 and the water tank 3 is realized by opening a connecting through hole 52 on the atomization bottom surface 51 of the atomization chamber 5. When the atomization chamber 5 is located around the side wall of the water tank 3, the communication mode between the atomization chamber 5 and the water tank 3 is realized by opening a connecting through hole 52 on the side wall of the water tank 3. When the atomization chamber 5 is located below the water tank 3, the communication mode between the atomization chamber 5 and the water tank 3 is realized by pipeline or hose connection, and a water pumping device or a pressurizing device is arranged, which can make the water in the atomization chamber 5 flow upward to the water tank 3.

[0275] In some embodiments, a connecting through hole 52 is opened on the atomization bottom surface 51 of the atomization chamber 5, and the connecting through hole 52 communicates the atomization chamber 5 and the water tank 3.

[0276] The atomization generator 4 is arranged on the atomization bottom surface 51 in the atomization chamber 5, and the connecting through hole 52 is arranged around the atomization generator 4 in the atomization chamber 5. Specifically, the connecting through hole 52 is configured in a circular arc shape and is arranged around the atomization generator 4. However, the shape of the connecting through hole 52 is not limited thereto, and according to different specific application scenarios, in some embodiments, the shape of the connecting through hole 52 can be (but not limited to) circular, polygonal, oval, or other regular shapes.

[0277] In some embodiments, the connecting through hole 52 is a gap formed between the atomization bottom surface 51 and the inner surface of the fan housing 1.

[0278] The atomized water vapor generated in the atomization chamber 5 will condense into liquid water under the action of factors such as large density and large internal and external temperature difference. The aggregation of liquid water will reduce the space in the atomization chamber 5, or the liquid water will submerge the atomization generator 4 and make it unable to work. The arrangement of the connecting through hole 52 can guide the liquid water formed in the atomization chamber 5 into the water tank 3, effectively avoiding the occurrence of the above adverse effects. It can also supplement the water in the water tank 3, reduce the number of times of supplementing the water in the water tank 3 by the user, and improve the user experience.

[0279] In some embodiments, the atomization bottom surface 51 is inclined or configured as an arc surface, and the connecting through hole 52 is at least partially structured and opened at the lowest position of the atomization bottom surface 51 in terms of horizontal height, so that the liquidized liquid in the atomization chamber 5 is easily flowed into the water tank 3.

[0280] When the atomization bottom surface 51 is inclined, the connecting through hole 52 is arranged at one end of the inclined surface and at the lowest end of the inclined surface. When the atomization bottom surface is an arc surface, the connecting through hole 52 is arranged at the lowest point of the arc surface.

[0281] The atomization bottom surface 51 of the atomization chamber 5 is configured as an inclined surface or an arc surface, which can converge the liquid water to the lowest position of the inclined surface or the arc surface, and has the effect of converging the liquid water. The liquidized channel 53 is connected at the lowest position of the atomization bottom surface 51 in terms of horizontal height, which can improve the liquid guiding efficiency of the liquidized channel 53, so that the liquidized liquid in the atomization chamber 5 is easily flowed into the water tank 3, and the liquid accumulation rate in the atomization chamber 5 is reduced.

[0282] In some embodiments, at least one separation barrier 54 is arranged on the atomization bottom surface 51, and each separation barrier 54 is arranged between two adjacent atomization generators 4.

[0283] In the present embodiment, at least two atomization generators 4 are arranged, and one separation barrier 54 is arranged between two adjacent atomization generators 4. If the number of atomization generators 4 is n, the number of corresponding separation barriers 54 is (n-1), and n is an integer greater than or equal to 2.

[0284] The separation barrier 54 in the present embodiment is used to avoid interference between the atomization generators 4. The closer the position to the atomization generator 4, the greater the concentration of the atomized water vapor, and the greater the concentration will cause the atomized water vapor to converge and condense into liquid water. Therefore, the interference between the two adjacent atomization generators 4 will accelerate the condensation of the two atomized water vapors into liquid water, and reduce the atomization efficiency. The arrangement of the separation barrier 54 physically separates the two adjacent atomization generators 4, reduces the probability of mutual interference, and improves the atomization efficiency of the atomization generator 4. At the same time, the arrangement of the separation barrier 54 can make the atomized water vapor at different positions in the atomization chamber 5 be distributed relatively uniformly and move directionally, which is beneficial to the uniform diffusion of the atomized water vapor to the outside, and makes the humidification effect of the humidification fan uniform.

[0285] The separation barrier 54 in the present embodiment is composed of two separation columns and a partition plate connecting the two separation columns. However, the structure of the separation barrier is not limited thereto, and in some embodiments, the separation barrier 54 can be (but not limited to) a smooth partition plate, a fence structure, etc.

[0286] In some embodiments, the connection through hole 52 is provided with a liquefaction channel 53 extending in the direction facing the water tank 3, the liquefaction channel 53 being in communication with the connection through hole 52 and the water tank 3.

[0287] The liquefaction channel 53 can guide the liquid water in the atomization chamber 5 to the water tank 3, rather than allowing the water to drop freely into the water tank 3 through the connection through hole 52. The liquefaction channel 53 can avoid the drop noise caused by the water droplets dropping into the water tank 3. At the same time, the liquefaction channel 53 is inserted into the water tank 3 to form a liquid seal, which can prevent the air flow in the atomization chamber 5 from flowing back into the water tank 3 when the air pressure in the atomization chamber 5 is greater than the air pressure in the water tank 3, thereby preventing the water level in the water tank 3 from fluctuating. The liquefaction channel 53 can also prevent the atomized water vapor in the atomization chamber 5 from diffusing out of the water tank 3 through the water inlet or other air leakage positions of the water tank 3, thereby improving the utilization rate of the atomized water vapor.

[0288] In the present embodiment, the liquefaction channel 53 can be a separate pipeline connected at the position of the connection through hole 52, or can be a gap channel formed by the partition plate 6 opposite to the fan housing 1.

[0289] In some embodiments, the liquefaction channel 53 includes a liquefaction overhanging end 531, and the atomization generator 4 includes an atomization overhanging end 41, the distance between the liquefaction overhanging end 531 and the bottom surface 31 of the water tank 3 is less than the distance between the atomization overhanging end 41 and the bottom surface 31 of the water tank 3.

[0290] The atomization overhanging end 41 of the atomization generator 4 represents the lowest water level at which the atomization generator 4 can absorb liquid. When the water level is below this lowest water level, the atomization generator 4 can no longer absorb liquid, and the water level in the water tank 3 will remain at this water level. At this time, when the air pressure in the atomization chamber 5 is relatively high, the air flow in the atomization chamber 5 will flow into the water tank 3 along the liquefaction channel 53, causing a series of problems such as an increase in air pressure in the water tank 3, fluctuation of the water level, or a decrease in the atomized water vapor blowing efficiency. In order to avoid these problems, the length of the liquefaction channel 53 is increased, so that the distance between the liquefaction overhanging end 531 of the liquefaction channel 53 and the bottom of the water tank 3 is smaller. Even if the water level in the water tank 3 reaches the lowest part of the atomization overhanging end 41 (the water level is just separated from the atomization overhanging end 41) due to the continuous operation of the atomization generator 4, the free end of the liquefaction channel 53 is still inserted into the water level, and the liquid seal is still formed, which can avoid the above problems, stabilize the air pressure in the water tank 3, stabilize the water level, and improve the atomized water vapor blowing efficiency.

[0291] In some embodiments, an atomization air inlet is formed in the air duct 14 of the humidifying fan, and the atomization air inlet is connected with the atomization chamber 5. When the atomization fan is in operation, the air pressure in the air duct 14 is greater than the air pressure in the atomization chamber 5, and the airflow in the air duct 14 flows into the atomization chamber 5 through the atomization air inlet, so that the air pressure in the atomization chamber 5 increases. At this time, if the liquefaction channel 53 is not provided and a liquid seal is not formed, the airflow and the atomized water vapor in the atomization chamber 5 will enter the inside of the water tank 3, which may cause the blockage of the water inlet of the water tank 3, the overflow of the atomized water vapor from the water inlet, or the combination of the atomized water vapor with the liquid water in the water tank 3, thereby reducing the air outlet efficiency of the humidifying fan and the blowing efficiency of the atomized water vapor. The provision and structure of the liquefaction channel 53 can avoid the above problems and improve the air outlet efficiency of the humidifying fan and the blowing efficiency of the atomized water vapor.

[0292] In some embodiments, a partition plate 6 is arranged in the fan housing 1, and a sandwiched space 16 is formed between the partition plate 6 and the inner surface of one side of the fan housing 1. The atomization air outlet 13 and the sandwiched space 16 are connected, and the atomization chamber 5 and the sandwiched space 16 are connected.

[0293] The sandwiched space 16 is formed in the inside of the fan housing 1, and the atomization chamber 5 and the atomization air outlet 13 are connected through the sandwiched space 16, so that the atomized water vapor can not flow randomly in the inside of the humidifying fan, the probability of the atomized water vapor contacting the electronic components and metal parts in the inside of the humidifying fan is reduced, the safety of the humidifying fan is improved, and the service life of the humidifying fan is prolonged. Meanwhile, the sandwiched space 16 also has the function of containing the atomized water vapor. During the starting process or the closing process of the humidifying fan, the air outlet of the humidifying fan is small or no air is outlet, so that the atomized water vapor generated by the atomization generator 4 cannot be blown out in time. These atomized water vapors spread randomly in the outside space, increase the humidity in the environment near the humidifying fan, and then affect the normal use of the humidifying fan, and even affect the safety of the humidifying fan in the long run. The containing function of the sandwiched space 16 can greatly reduce the probability of the atomized water vapor spreading to the outside during the above process. The atomized water vapor that is not blown out in time will gather into liquid water that cannot float in the sandwiched space 16, reduce the influence of the atomized water vapor on the humidity of the environment around the humidifying fan, and further improve the safety of the humidifying fan.

[0294] The sandwiched space 16 formed by the partition plate 6 in the inside of the fan housing 1 has a larger space area and can contain more atomized water vapor. Meanwhile, the larger sandwiched space 16 has more connection positions between the fan air outlet 12 and the sandwiched space 16, so that the humidifying fan can be provided with more atomization air outlets 13.

[0295] In some embodiments, the atomization chamber 5 is formed in the sandwiched space 16. The atomization chamber 5 is arranged in the sandwiched space 16 between the partition plate 6 and the front housing, so that the distance between the atomization chamber 5 and the sandwiched space 16 is shortened, the flow distance of the atomized water vapor is reduced, and the blowing efficiency of the atomized water vapor is improved.

[0296] In some embodiments, the partition plate 6 is bent to form an atomization bottom surface 51 on the side facing the fan outlet 12 of the fan housing 1, and the atomization bottom surface 51 and part of the structure of the fan housing 1 enclose to form an atomization chamber 5.

[0297] The atomization bottom surface 51 is formed by bending the partition plate 6, which can simplify the formation structure of the atomization bottom surface 51, make the structure of the atomization bottom surface 51 more simple, and occupy less space. At the same time, since the partition plate 6 plays a role in preventing atomized water vapor from spreading into the fan, the one-piece bending to form the atomization bottom surface 51 reduces the connection and splicing positions, so that the sealing effect of the partition plate 6 is better and the protection effect is better.

[0298] In some embodiments, the partition plate 6 extends toward the water tank 3 to form a first vertical plate 61, and the fan housing 1 extends toward the water tank 3 to form a second vertical plate 15, and the first vertical plate 61 and the second vertical plate 15 enclose to form a liquefaction channel 53.

[0299] The first vertical plate 61 is extended by the partition plate 6, the second vertical plate 15 is extended by the fan housing 1 toward the water tank 3, and the liquefaction channel 53 is enclosed by the first vertical plate 61 and the second vertical plate 15. The process of forming the liquefaction channel 53 is simplified, the space occupied is smaller, and in the case of limited space size, the volume of the water tank 3 is larger, which can hold more humidifying water.

[0300] In some embodiments, the first vertical plate 61 extends to form a first edge 62 and a second edge 63 on the two sides, respectively, facing the second vertical plate 15, and the first edge 62 and the second edge 63 are connected with the second vertical plate 15, respectively.

[0301] By setting the first edge 62 and the second edge 63, the first vertical plate 61 and the second vertical plate 15 become a closed space, and the air tightness is better.

[0302] It should be noted that any embodiment in the present embodiment can be independently implemented, or implemented by being combined with one or more other embodiments. When combined, the combination manner should not be limited to the combination manner listed in the present embodiment.

[0303] It should be noted that the preferred embodiments of the present application are described in the specification and its attached drawings, but the present application can be implemented in many different forms and is not limited to the embodiments described in the specification, and these embodiments are not intended to be additional limitations on the content of the present application, and the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. Furthermore, each of the above technical features continues to combine to form various embodiments not listed above, which are considered to be within the scope of the present application specification; further, for those skilled in the art, the above description can be improved or changed, and all these improvements and changes shall fall within the scope of protection of the claims of the present application.
