The above are different arrangements of the water return hole 1121 and the mist outlet hole 1111 on the metal sheet 11, and in actual application and production, the number of the water return hole 1121 and the mist outlet hole 1111, the arrangement of the water return hole 1121 and the mist outlet hole 1111, the distance between the water return hole 1121 and the mist outlet hole 1111, and the distance between the water return hole 1121 and the mist outlet hole 1111 can be adjusted according to different use scenarios and actual conditions, so as to achieve the maximum humidifying efficiency of the humidifier and a good solution to the problem of water accumulation. Figures 2 to 8 In the figure, “.” represents the mist outlet hole 1111, and “+” represents the water return hole 1121, and the size does not represent the size of the mist outlet hole 1111 or the water return hole 1121.

[0024] Preferably, as shown in FIGS. 4B, 4C, 4D, and 4E, when the water return area 112 and the mist outlet area 111 are arranged in a circumferential direction, the water return area 112 and the mist outlet area 111 are arranged in the same plane, and the metal sheet 11 is a plane, and the water inlet and the water outlet of all the mist outlet holes 1111 and the water return holes 1121 are in the same horizontal plane, the mist is sprayed vertically upward from the mist outlet hole 1111, and the condensed water is also sprayed vertically downward through the water return hole 1121 under the action of the ultrasonic atomization sheet or flows back to the water tank. Figure 2 9 or, the water return area 112 and the mist outlet area 111 are arranged in a circumferential direction around the center part 113, as shown in FIG. 4B; or, the water return area 112 and the mist outlet area 111 are arranged from the center part 113 to the peripheral part 114, and the water return area 112 and the mist outlet area 111 are arranged in a circumferential direction and are spaced apart, as shown in FIG. 4C; or, the water return area 112 is arranged in a grid shape, and the mist outlet area 111 is arranged in a plurality of grids formed by the water return area 112, as shown in FIG. 4D; or, the mist outlet area 111 is arranged in a grid shape, and the water return area 112 is arranged in a plurality of grids formed by the mist outlet area 111, as shown in FIG. 4E. Figure 10 ​, the backwater area 112 is upwardly convex, and the backwater holes 1121 are distributed on the convex part. The convex part can have a regular shape such as a cube, a cuboid, a hemisphere, etc. with a platform. The specific shape can be selected according to the actual working scene. Similarly, the mist outlet area 111 is downwardly concave. Alternatively, the backwater area 112 and the mist outlet area 111 can be both upwardly convex or both downwardly concave, or have different convex or concave heights. Alternatively, one of the two is a plane, and the other is a sphere. When the mist outlet area 111 is a plane, the backwater area 112 is a sphere. In this case, the condensed water can be quickly collected into the spherical backwater area 112, thereby accelerating the back-spraying and / or backflow of the condensed water. Conversely, when the backwater area 112 is a plane, the mist outlet area 111 is a sphere. In this case, the mist is sprayed at a certain angle with the horizontal plane, and the mist is relatively dispersed, which is suitable for large-capacity humidification.

[0025] Preferably, as shown in Figure 2 , when the backwater area 112 and the mist outlet area 111 are arranged around each other, the mist outlet area 111 and the backwater area 112 further comprise a transition area 115 arranged around. The transition area 115 can reduce the processing difficulty of the atomizing piece 1 without changing the original equipment.

[0026] Preferably, as shown in Figure 9 , when the mist outlet area 111 or the backwater area 112 is the sphere, the transition area 115 comprises a first transition area 1151 and / or a second transition area 1152. In order to facilitate the reduction of condensed water or the improvement of the back-spraying and / or backflow efficiency of the condensed water, the first transition area 1151 is located on the sphere and arranged around the mist outlet hole 1111 or the backwater hole 1121, and / or the second transition area 1152 is arranged at the edge of the backwater area 112 or the mist outlet area 111 and arranged around the backwater hole 1121 or the mist outlet hole 1111.

[0027] In another embodiment, as shown in Figure 10When the water return area 112 is arranged around the mist area 111, the water return area 112 is a downwardly recessed annular groove 116, which can better receive the condensed water and increase the capacity of storing the condensed water, so as not to overflow to the desktop or other humidifier carriers; the cross section of the annular groove 116 can be trapezoidal or semicircular. Taking the trapezoidal cross section as an example, the annular groove 116 is composed of a first side 1161, a second side 1162 and a bottom 1163; the water return hole 1121 is arranged on the bottom 1163, and / or the first side 1161, and / or the second side 1162, that is, the arrangement position of the water return hole 1121 can be selected according to the actual situation. The water return hole 1121 arranged at different positions has different effects on the back spray and / or backflow of the condensed water. In the actual working scene, the position and number of the water return hole 1121 can be adjusted according to the needs. Similarly, when the cross section is semicircular, the semicircle can be divided into two sides and a bottom, and the specific arrangement of the water return hole 1121 is the same as above, which will not be described here. When the cross section of the annular groove 116 is semicircular, the water return hole 1121 is arranged on the bottom 1163 and the second side 1162, which has the highest efficiency of back spray and / or backflow of the condensed water.

[0028] In another embodiment, in order to facilitate processing and to make the mist area 111 and the water return area 112 more stable, the metal sheet 11 is integrally formed, and the mist area 111 and the water return area 112 are formed on the integrally formed metal sheet 11; or, because the wear degrees of the mist area 111 and the water return area 112 are inconsistent during use, arranging the mist area 111 and the water return area 112 on separate metal sheets is beneficial for separate replacement, which is more economical and practical. The metal sheet 11 includes a first metal sheet (not shown in the figure) and a second metal sheet (not shown in the figure), the mist area 111 is formed on the first metal sheet, and the water return area 112 is formed on the second metal sheet.

[0029] In another embodiment, as Figure 11, the metal sheet 11 includes a first surface 117 for misting and a second surface 118 away from the first surface 117, the cross-sectional area of the misting hole 1111 gradually decreases from the second surface 118 to the first surface 117 to form a truncated cone shape, which can facilitate the increase of pressure when the mist enters the misting hole 1111, the mist can be sprayed farther, and the condensate can be reduced near the misting hole. The cross-sectional area of the water return hole 1121 gradually decreases from the first surface 117 to the second surface 118 to form a truncated cone shape and achieve anti-toppling and water leakage. And / or, the diameter of the misting hole 1111 is between 2-8μm, the size of the misting hole 1111 can affect the size of the mist, and the problem of clogging the hole, the present application can be larger than the general misting hole 1111 due to the setting of the water return hole, which can not only reduce the difficulty of processing, but also solve the problem of clogging the hole while increasing the humidification amount. As for the size of the misting hole 1111, it can be set to 3μm, 4μm, 5μm, 6μm, 7μm, etc. according to the actual use scene and the humidification amount requirement. The setting of each scene is not described in detail here.

[0030] In one embodiment, when the humidifier is used to atomize pure water, the atomizing sheet 1 reversely atomizes the accumulated water formed by the water return hole 1121 to return the accumulated water back into the humidifier. The top surface of the shell 2 is also provided with an atomizing opening corresponding to the atomizing sheet 1, and the number of the atomizing opening is one or two. When the atomizing opening is one, the atomizing opening is located at the center of the top surface of the shell 2. When the atomizing sheet 1 is two, the atomizing opening is located on the axisymmetric position of the top surface of the shell 2, which is more beautiful and beneficial to the stable operation of the humidifier.

[0031] The above detailed description is only a description of the preferred embodiment of the present application, and is not limited to the scope of the patent. Therefore, any equivalent technical changes made according to the description and drawings of the present application are included in the scope of the patent.
