[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: Reference Figures 1-7 This utility model provides a mist-free humidifier air outlet device, comprising: The flow guiding assembly includes an upper flow guiding component 9 and a lower flow guiding component 8. The upper flow guiding component 9 is fixedly connected to the top of the lower flow guiding component 8. Air outlets are provided on several side walls of the upper flow guiding component 9 and the lower flow guiding component 8, and an air inlet is provided at the bottom of the lower flow guiding component 8. The wind turbine assembly includes a centrifugal wind turbine 7 disposed between the upper guide member 9 and the lower guide member 8, and a rotation drive member is disposed between the centrifugal wind turbine 7 and the upper guide member 9.

[0020] The main functions of the upper guide member 9 and the lower guide member 8 are to guide the airflow blown out from the centrifugal impeller 7, so that the airflow is blown out from the side rather than the top; the main function of the air inlet is to provide an air intake channel for the centrifugal impeller 7; the main function of the rotation drive member is to drive the centrifugal impeller 7 to rotate. Overall, this utility model encloses the centrifugal impeller by setting up interconnected upper and lower guide members, and opens several air outlets on the side wall of the guide assembly formed by the upper and lower guide members, which helps to generate airflow when the centrifugal impeller rotates and to guide the airflow from the side, so as to achieve the effect of side air outlet.

[0021] Further optimization of the design resulted in the adoption of a backward centrifugal impeller for centrifugal impeller 7.

[0022] Further optimization of the scheme: the rotation drive component includes a motor 6 fixedly connected to the top of the upper guide 9, and the output shaft of the motor 6 is connected to the top of the centrifugal impeller 7 via a transmission connection.

[0023] To further optimize the design, the bottom of the lower guide component 8 is provided with a first annular guide arc surface 81. The bottom end of the first annular guide arc surface 81 is connected to the edge of the air inlet, and the top end of the first annular guide arc surface 81 is connected to the bottom edge of several air outlets.

[0024] like Figure 4 As shown, the two sides of the first annular guide arc surface 81 smoothly transition with the top edge of the air inlet and the bottom inner edge of the air outlet, which is conducive to the stable flow of air and smoother air outlet.

[0025] In a further optimized design, a second annular guide arc surface 91 is provided inside the upper guide component 9. One side of the second annular guide arc surface 91 is connected to the top of the upper guide component 9, and the other side of the second annular guide arc surface 91 is connected to the top edge of several air outlets.

[0026] like Figure 4As shown, the top inner edge of the air outlet and the top of the upper guide 9 are smoothly transitioned by the second annular guide arc surface 91, making the top height of the air outlet higher than the height of the middle of the top of the upper guide 9.

[0027] The centrifugal impeller 7 is further optimized by including an upper impeller plate 71 and a lower impeller plate 72. The upper impeller plate 71 and the lower impeller plate 72 are fixedly connected by several fan blades. The edge of the upper impeller plate 71 is provided with an upward tilting edge, and the edge of the lower impeller plate 72 is provided with a downward tilting edge. Within the cross-section passing through the axis of the centrifugal impeller 7, the lower inclination edge is set parallel to the first annular guide arc surface 81, and the upper inclination edge is set parallel to the second annular guide arc surface 91.

[0028] Further optimize the plan, such as Figure 4 As shown, the minimum distance between the downward tilting edge and the first annular guide arc surface 81 is A, and the vertical distance between the top of the downward tilting edge and the bottom of the air outlet is B. Then -A < B < +A. The distance between the top of the upper inclined edge and the top of the upper guide 9 is C, and the vertical distance between the upper inclined edge and the top of the air outlet is D. Then D < 5C.

[0029] A mist-free humidifier includes: The body 1 has a front air outlet 3 and two side air outlets 4 respectively on its three side walls. The side walls of the body 1 also have air inlets 5. The body 1 is equipped with the above-mentioned mist-free humidifier air outlet device. Several air outlets are connected to the front air outlet 3 and the side air outlets 4 respectively. The evaporative cooling pad assembly includes an evaporative cooling pad 11, which is located at the bottom of the lower air guide 8. The air inlet 5 is connected to the air inlet through the evaporative cooling pad 11, and a humidification mechanism is provided between the evaporative cooling pad 11 and the main body 1.

[0030] The main function of the front air outlet 3 and the two sets of oppositely arranged side air outlets 4 is to allow the air blown by the centrifugal impeller 7 to be discharged from the side wall of the unit 1, thereby avoiding the pollution problem caused by top air outlets. The main function of the wet curtain 11 is to allow ambient air to pass through the wet curtain 11 and come into contact with the water adsorbed inside the wet curtain 11, increasing the air humidity before it is discharged from the unit 1 through the centrifugal impeller 7, achieving the effect of fog-free humidification of air. Overall, this utility model, by placing the wet curtain below the centrifugal impeller, allows air to pass through the wet curtain and then enter the centrifugal impeller through the air inlet, and finally be discharged into the room from the front air outlet and side air outlets, thus avoiding the pollution problem caused by upward air outlets and achieving the purpose of fog-free humidification of air.

[0031] like Figure 3 and Figure 4 As shown, the wet curtain 11 is cylindrical, and its inner side is connected to the centrifugal impeller 7 through the air inlet. Air passes through the wet curtain 11 and flows into the centrifugal impeller 7.

[0032] Further optimize the plan, such as Figure 5 As shown, a grille 10 is also fixedly connected inside the body 1. The grille 10 is located between the lower guide 8 and the top water tank 17.

[0033] Further optimization of the design involves creating air outlets on the side wall of the unit. Horizontally, the angle between the leftmost and rightmost air outlets must be less than or equal to 280 degrees to reserve some space where no airflow is required. This prevents the humidifier from wetting the wall when placed against it.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the front air outlet 3 and the two side air outlets 4 of the main body 1 form a structure with three side air outlets. Alternatively, the outlets can be limited to the front of the entire unit, with a maximum deflection of 140 degrees to the left and right, so that the total air outlet angle is less than or equal to 280 degrees. Because the humidifier's air outlet will blow out moisture, it will wet the wall if placed against it. Therefore, no air outlet is opened at the rear.

[0035] The humidification mechanism further optimizes the design by including a water storage tank 2, which is detachably connected to the body 1. A top water tank 17 is also fixedly connected inside the body 1. The top water tank 17 and the water storage tank 2 are connected through a water pump. The top water tank 17 is fixedly connected to the top of the wet curtain 11. Several water holes 18 are provided at the bottom of the top water tank 17 for wetting the wet curtain 11. A lower water tank 12 is fixedly connected to the bottom of the wet curtain 11.

[0036] The scheme is further optimized. The water pump component includes a water pump 14 fixedly connected inside the body 1. The water inlet of the water pump 14 is connected to the water storage tank 2, and the water outlet of the water pump 14 is connected to the top water tank 17 through a solenoid valve 15.

[0037] In a further optimized design, the side wall of the top water tank 17 is connected to an inlet 16, which is connected to the outlet of the solenoid valve 15.

[0038] like Figures 1-3 As shown, the water in the water storage tank 2 is pumped to the top water tank 17 by the water pump 14, and then flows evenly into the wet curtain 11 through several water holes 18, so that the wet curtain 11 is in a uniformly humid state. When the air passes through the wet curtain 11 and enters the inside of the wet curtain 11 from the outside, it can come into contact with the water in it, thereby increasing the air humidity.

[0039] Example 2: A secondary water tank 20 is fixedly connected to the bottom of the lower water tank 12. Several water leakage holes 19 are opened at the bottom of the lower water tank 12 and communicate with the secondary water tank 20. A column 21 is fixedly connected vertically inside the secondary water tank 20. A float 22 is slidably sleeved on the column 21. A Hall plate 13 is fixedly connected to the outer wall of the secondary water tank 20. The Hall plate 13 is correspondingly set with the float 22. The Hall plate 13 is used to detect the height of the float 22.

[0040] like Figure 3 and Figure 7 As shown, water enters the lower water tank 12 through the wet curtain 11 and then enters the auxiliary water tank 20 through the drain hole 19. The water in the auxiliary water tank 20 can drive the float 22 to rise together, thereby obtaining the position of the float 22 through the electromagnetic induction between the float 22 and the Hall plate 13.

[0041] When the float 22 is too low, it indicates that the water level in the auxiliary water tank 20 is too low. At this time, the moisture in the wet curtain 11 is also too low. The water pump 14 starts running and the solenoid valve 15 opens, allowing water to flow to the wet curtain 11 and increasing the humidity of the wet curtain 11.

[0042] As water is replenished, it eventually flows into the auxiliary water tank 20. When the water level in the auxiliary water tank 20 is too high, the water pump 14 stops operating and the solenoid valve 15 is closed to prevent water from accumulating in the lower water tank 12 and to prevent the wet curtain 11 from being soaked in water.

[0043] The main body 1 is also equipped with a control unit, which is used to control the operation of the motor 6, water pump 14, solenoid valve 15 and Hall plate 13.

[0044] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
