[0008] Preferably, a return pipe is fixedly connected to the bottom surface of the terminating end of the mist outlet section, and the return pipe extends downward into the mist-generating chamber.

[0009] Preferred options also include: A blower is fixed inside the housing. An air inlet is provided on the side of the mist pipe away from the mist channel. The air outlet of the blower is vertically downward toward the air inlet.

[0010] Preferably, the guiding mechanism includes: A plurality of first guide plates are connected to the air outlet. A drive assembly is disposed within the housing. The drive end of the drive assembly is connected to the plurality of first guide plates to enable the plurality of first guide plates to rotate continuously. Several second guide plates are connected to the first guide plate on the side near the wind turbine. An actuating assembly is provided inside the housing, and the driving end of the actuating assembly is connected to several second guide plates. The first guide plate and the second guide plate are perpendicular to each other.

[0011] Preferably, the driving component includes: A stepper motor is fixedly connected inside the housing. A drive gear is fixedly connected to the output shaft of the stepper motor. A driven gear is rotatably connected inside the housing. The drive gear meshes with the driven gear. A positioning rod is fixed to the axis of the driven gear. A transmission plate is slidably connected inside the air duct. A positioning hole is opened on the transmission plate. The positioning rod slides in contact with the inner wall surface of the positioning hole.

[0014] Technical effects: This invention utilizes a fan to direct strong convective wind to the air outlet, and positions the mist outlet below it via a mist channel. The mist outlet area is distributed obliquely upwards. A guiding mechanism within the air outlet changes the wind direction, thereby altering the direction of the atomized water sprayed from the mist outlet, achieving uniform atomized humidification. Furthermore, the mist channel structure is designed with protrusions to create cavities, connecting the beginning of the mist outlet area to these cavities. This allows the atomized water to enter through the mist inlet, swirling through the cavity, and then exiting through the mist outlet area. This effectively reduces the direct spraying of atomized water, minimizing water accumulation at the mist outlet. The off-center alignment of the mist inlet and outlet positions further prevents direct spraying of atomized water, enhancing the user experience. Attached Figure Description

[0019] It should be noted that in this utility model, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in this utility model should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0020] In this invention, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between the related objects, indicating that three relationships can exist.

[0021] like Figures 1-7 As shown, a fan-type humidifier includes a housing 1, which defines an air intake chamber and a mist-generating chamber from top to bottom; a fan wheel 2, which is connected to the air intake chamber; an air outlet is provided on one side of the housing 1, and the air outlet end of the fan wheel 2 faces the air outlet; and a guide mechanism is provided in the air outlet, which is used to change the direction of the airflow passing through the air outlet. The mist channel 3 is fixedly connected to the mist-generating chamber. The mist channel 3 has a mist outlet 6 that penetrates the housing 1. The mist outlet 6 extends upward at an angle and defines a mist outlet range. The mist outlet 6 is arranged below the air outlet. A protrusion 5 is integrally formed on one side of the top surface of the mist channel 3. A cavity is opened in the protrusion 5. The starting end of the mist outlet range is connected to the cavity. The mist inlet 10 of the mist channel 3 is inclined upward toward the cavity. The gas entering the cavity is vortex-shaped. The mist tube 4 is fixedly connected to the mist-generating chamber. An atomizing component is installed in the mist tube 4. The top end of the mist tube 4 is eccentrically connected to the mist inlet 10.

[0022] This invention utilizes a fan wheel 2 to apply strong convective wind force to the air outlet, and a mist outlet 6 is positioned below the air outlet via a mist channel 3. The direction of the mist outlet section is distributed obliquely upwards. By using a guiding mechanism within the air outlet to change the airflow direction, the direction of the atomized water sprayed from the mist outlet 6 is also changed, achieving uniform spraying of atomized humidification. In addition, by designing the structure of the mist channel 3, a cavity is created using the structural protrusion 5 formed by the mist channel 3, and the starting end of the mist outlet section is connected to the cavity. This allows the atomized water to enter from the mist inlet 10, pass through the cavity in a vortex-shaped mist pattern, and then be sprayed out from the mist outlet 6 after passing through the mist outlet section. This effectively improves the situation of direct spraying of atomized water, reduces water accumulation at the mist outlet 6, and also eccentrically aligns the mist inlet 10 with the mist outlet position of the mist pipe 4, further preventing direct spraying of atomized water from the mist outlet 6 and improving the user experience.

[0023] Furthermore, the atomizing components include: The buoyancy seat 7 is slidably connected inside the mist tube 4. A hollow groove is opened at the bottom of the buoyancy seat 7, and an ultrasonic atomizer 8 is fixedly connected in the hollow groove. A conveying channel 9 is opened at the top of the buoyancy seat 7. The bottom end of the conveying channel 9 is connected to the ultrasonic atomizer 8. The top of the conveying channel 9 has a conical structure, and the mist inlet 10 is connected to one side of the top of the conveying channel 9.

[0024] The buoyancy seat 7 slides inside the mist tube 4, allowing the buoyancy seat 7 to adaptively adjust its position according to the water level. The ultrasonic atomizer 8 is installed inside the buoyancy seat 7. Water is introduced into the buoyancy seat 7 through the empty slot, keeping the ultrasonic atomizer 8 in contact with the water. The built-in oscillating plate generates fine atomized water, which is then sent into the mist inlet 10 along the conical conveying channel 9 to achieve atomization.

[0025] Furthermore, the central area of ​​the fog exit zone narrows from both sides towards the center.

[0026] By narrowing the mist channel 3 in the middle of the mist outlet area, the flow rate of atomized water is effectively increased, thereby enhancing the humidification effect.

[0027] Furthermore, a return pipe 11 is fixedly connected to the bottom surface of the end of the mist outlet section, and the return pipe 11 extends downward into the mist-generating chamber.

[0028] By utilizing the return pipe 11 fixed to the mist channel 3, and with the return pipe 11 positioned at the end of the mist outlet section (i.e., the mist outlet 6 is located on one side inside the housing 1), water droplets that condense and adhere to the inner wall of the mist channel 3 after tilting upwards can be collected, effectively reducing water retention at the mist outlet 6. Furthermore, it also includes: The blower 12 is fixed inside the housing 1. The mist pipe 4 has an air inlet on the side away from the mist channel 3. The air outlet of the blower 12 is vertically downward toward the air inlet.

[0029] The blower 12 blows air toward the mist pipe 4, thereby providing the power for the atomized water to enter the mist channel 3 from the mist pipe 4, ensuring the humidification function of spraying atomized water.

[0030] Furthermore, the guiding institutions include: A plurality of first guide plates 13 are connected to the air outlet. A drive assembly is provided inside the housing 1, and the drive end of the drive assembly is connected to the plurality of first guide plates 13 so that the plurality of first guide plates 13 rotate continuously. A plurality of second guide plates 14 are connected to the side of the first guide plates 13 near the impeller 2. A toggle assembly is provided inside the housing 1, and the drive end of the toggle assembly is connected to the plurality of second guide plates 14. The first guide plates 13 and the second guide plates 14 are perpendicular to each other in the horizontal direction of the air outlet.

[0031] By driving the component to electrically control the continuous rotation of several first guide plates 13, the airflow direction is continuously changed, ensuring uniform airflow from the air outlet, which in turn drives the atomized water sprayed from the mist outlet 6 to humidify evenly. The second guide plate 14 is perpendicular to the first guide plate 13 and can be manually adjusted by toggling the component. The humidification direction can be effectively changed according to the user's needs, enhancing the user experience.

[0032] Furthermore, the driving components include: A stepper motor 15 is fixedly connected inside the housing 1. The output shaft of the stepper motor 15 is fixedly connected to a drive gear 16. A driven gear 17 is rotatably connected inside the housing 1. The drive gear 16 meshes with the driven gear 17. A positioning rod 18 is fixed to the shaft of the driven gear 17. A transmission plate 20 is slidably connected inside the air duct. A positioning hole 19 is opened on the transmission plate 20. The positioning rod 18 slides in contact with the inner wall surface of the positioning hole 19. Among them, several first guide plates 13 are evenly distributed and are all connected to the side of the transmission plate 20 away from the positioning hole 19.

[0033] The stepper motor 15 drives the driven gear 17 to rotate, which is rotatably connected by the positioning rod 18. The positioning rod 18 slides in contact with the positioning hole 19, thereby guiding the transmission plate 20 to move. The transmission plate 20 reciprocates along the opening structure of the positioning hole 19, and the transmission plate 20 is rotatably connected to several first guide plates 13, so as to drive several first guide plates 13 to rotate synchronously and realize the function of uniformly changing the wind direction.

[0034] Specifically, the two ends of the first guide plate 13 are rotatably connected to the inner wall of the air outlet in a vertical direction, and an eccentric shaft 21 is fixed to the side of the first guide plate 13 near the transmission plate 20. The eccentric shaft 21 is eccentrically positioned relative to the central axis of rotation of the first guide plate 13. The eccentric shaft 21 is rotatably connected to the transmission plate 20, and several eccentric shafts 21 on the first guide plates 13 are arranged sequentially in the same straight line direction. As the transmission plate 20 moves along the positioning hole 19, it drives the eccentric shaft 21 to synchronously rotate several first guide plates 13, thereby adjusting the airflow direction. The rotation principle of the aforementioned several first guide plates 13 is the same as the movement principle of common air conditioner horizontal airflow blades, which is existing technology and will not be described in detail.

[0035] Furthermore, the toggle assembly includes: A lever 22 is connected to the side wall of the housing 1. One end of the lever 22 extends out of the housing 1, and the other end of the lever 22 that extends into the air duct is fixedly connected to a clamp 23. A rotating rod 24 and an adjusting rod 25 are fixedly connected to both sides of the second guide plate 14, respectively. The rotating rod 24 is connected to the air duct. A sliding plate is slidably connected in the vertical direction inside the air duct. The adjusting rod 25 is hinged to the moving plate 26. A locking pin 27 is fixedly connected to one side of the moving plate 26. The locking pin 27 extends into the clamp 23 and is rotatably connected to the clamp 23.

[0036] By connecting the lever 22 to the side wall of the housing 1 at the middle position, the two ends of the lever 22 rotate around the connection position with the housing 1, thereby adjusting the height of the clamp 23. The clamp 27 is engaged in the clamp 23, and the clamp 23 maintains the transmission connection with the clamp 27 during the lifting and rotating process. The clamp 27 pushes the moving plate 26 to lift and slide, thereby adjusting the height of the adjusting rod 25. The second guide plate 14 is rotated around the rotating rod 24 through the rotating rod 24, thereby realizing the manual adjustment of the vertical wind direction.

[0037] Furthermore, an air duct 28 is fixedly connected inside the air intake cavity. The air duct 28 is located on the side of the impeller 2 away from the air outlet. The air duct 28 extends downward at an angle along the bottom of the impeller 2, and the bottom end of the air duct 28 faces the air outlet in a horizontal direction.

[0038] By driving the impeller 2 through a drive motor fixed inside the housing 1, the impeller 2 rotates to draw in external air and blow it onto the air duct 28, which then guides it to the air outlet, creating a strong convective wind force that acts on the air outlet.

[0039] This utility model also provides a working principle for a fan-type humidifier: The impeller 2, blower 12, and ultrasonic atomizer 8 are started. The blower 12 provides airflow to release the atomized water generated by the vibration through the conveying channel 9. The inlet 10 of the mist channel 3 is eccentrically arranged with the buoyancy seat 7 to reduce the direct spraying of atomized water. The atomized water enters the cavity along the inlet 10 and is transported through the vortex flow in the cavity and the upward flow in the mist outlet section, which improves the effect of reducing the direct spraying of atomized water. In addition, the return pipe 11 is connected at the end of the mist outlet section to collect and recover the condensed water, thereby reducing the water retention at the mist outlet 6.

[0040] The fan wheel 2 provides strong convective airflow to the air outlet. The first guide plate 13 and the second guide plate 14 change the airflow direction in the horizontal and vertical directions. By setting the mist outlet 6 below the air outlet, the wind force blown out of the air outlet acts on the mist outlet 6, thereby spraying atomized water out of the mist outlet 6 along various wind directions, improving the humidification uniformity of the humidifier.
