Please refer to FIG2 . In this embodiment, the water tank body 1 includes a sealed upper cover 11 and a bottom shell 12 of the water tank. The upper cover 11 and the bottom shell 12 of the water tank are sealed and used to hold water. Please refer to FIG2 and FIG3 . An air outlet channel 114 is provided inside the upper cover 11 of the water tank. The air outlet channel 114 is isolated from water. One end of the air outlet channel 114 is an air outlet 112 located on the upper end surface of the upper cover 11 of the water tank, and the other end is an air inlet 113 located on the lower end surface of the upper cover 11 of the water tank. Please refer to FIG2 and FIG4 . A water inlet 121 and an air inlet 122 are provided on the bottom shell 12 of the water tank. The water inlet 121 is opened and closed by a water tank cover 120 . The water tank cover 120 is threadedly connected to the water inlet 121 , as shown in FIG7 . The air inlet 122 corresponds to and butts with the air inlet 113 of the air outlet channel 114 .

As shown in Figures 2 and 5, the base assembly 2 includes a middle frame 22 carried under the water tank body 1 and a bottom plate 21 installed at the lower end of the middle frame 22. The middle frame 22 is provided with a water inlet groove 221 and an atomizing groove 222, and the openings of the water inlet groove 221 and the atomizing groove 222 are both facing the direction of the water tank body 1. The water inlet groove 221 is arranged corresponding to the water tank cover 120, and the water tank cover 120 is also provided with an elastic switch (not shown). When the water tank body 1 is taken out separately, the elastic switch is closed, and no water will leak out of the water tank body 1. When the water tank body 1 is installed on the base assembly 2, the elastic switch is opened, and the water in the water tank body 1 flows to the water inlet groove 221. The water inlet groove 221 and the atomizing groove 222 are interconnected, and the atomizing assembly is arranged in the atomizing groove 222. The atomizing assembly can be, for example, an ultrasonic atomizing sheet. After the water flows to the atomizing groove 222, it is atomized by the atomizing assembly to form water mist. In addition, a fan assembly is provided in the base assembly 2, and an air outlet (not shown) is formed on one side of the base assembly 2 facing the water tank body 1. The airflow from the air outlet drives the water mist to flow, and gradually flows from the air inlet 113 and the air outlet channel 114 to the outside of the water tank body 1 to achieve the humidification function. The bottom surface of the atomizing groove 222 can be lower than the bottom surface of the water inlet groove 221, as shown in FIG6 .

As shown in Figure 3, in this embodiment, an observation window 111 in the shape of a strip and extending in the up and down direction is provided on the water tank cover 11. The observation window 111 is transparent, and other parts of the water tank cover 11 are opaque. Light is projected through the observation window 111, and the water level inside the water tank body 1 can be clearly indicated through the observation window 111.

In this embodiment, the water tank body 1 includes a water tank upper cover 11 and a water tank bottom shell 12 that are sealed and connected, and a transparent light board cover 5 that is sealed and installed on the water tank bottom shell 12. The accommodating space 10 is formed by the transparent light board cover 5 that is sealed and installed on the water tank bottom shell 12. As shown in Figures 2 and 9, a mounting portion 126 is provided on the water tank bottom shell 12, and the four sides of the transparent light board cover 5 are sealed and connected to the mounting portion 126, so that water contained outside the accommodating space 10 will not affect the light board 3 inside it.

Specifically, the assembly method of the water tank body 1 is to separately manufacture the water tank upper cover 11 and the water tank bottom shell 12, and then seal and install the transparent light board cover 5 on the water tank bottom shell 12 by ultrasonic welding, and then seal and install the water tank upper cover 11 on the water tank bottom shell 12 by ultrasonic welding. The advantage of this is that since the water tank upper cover 11 and the water tank bottom shell 12 can be manufactured by existing materials and methods, there is no need to change the process on a large scale, and only one transparent light board cover 5 needs to be welded.

The accommodating space 10 is connected to the outside. As shown in Figures 4 and 9, at least one first through hole 124 is provided on the water tank bottom shell 12 at a position corresponding to the transparent light board cover 5. The electrical connection between the light board 3 and the charging board 4 in the base assembly 2 is realized through the first through hole 124.

Specifically, referring to Figures 5, 6 and 8, the middle frame 22 is provided with a second through hole 225 corresponding to the first through hole 124, the charging plate 4 disposed inside the base assembly 2 includes a second circuit board 41 and two spring conductive pins 42 electrically connected to the second circuit board 41, the second circuit board 41 is located on the side of the middle frame 22 facing the bottom plate 21, and the two spring conductive pins 42 pass through the second through hole 225 and the first through hole 124 and enter the interior of the accommodating space 10, as shown in Figure 9. In other embodiments, the spring conductive pin 42 can be replaced by a non-elastic conductive pin.

The first circuit board 31 of the light board 3 is provided with conductive electrodes (not shown) which are electrically connected to the two spring conductive pins 42, and are specifically arranged on one side of the first circuit board 31 facing the base assembly 2, and the light-emitting element 32 is correspondingly arranged on the other side to facilitate light emission. The conductive electrode can be in the form of an electrode sheet. The spring conductive pins 42 and the conductive electrodes are in contact and electrically connected in an elastic pressing manner, which ensures the reliability of the electrical connection.

In this embodiment, the number of the first through hole 124 and the second through hole 225 are both two, corresponding to one spring conductive pin 42 respectively, so that the two spring conductive pins 42 can be separated as much as possible to reduce the risk of short circuit. The distance between the two conductive electrodes and the distance between the two spring conductive pins 42 can be designed to be as large as possible according to the size of the transparent light board cover 5.

As shown in Figures 5, 8 and 9, a protrusion 223 is provided on the side of the middle frame 22 facing the water tank body 1 corresponding to the position of the charging plate 4, and a recessed portion 123 is provided on the water tank bottom shell 12 corresponding to the protrusion 223. When the water tank body 1 is placed on the base assembly 2, the protrusion 223 is engaged in the recessed portion 123, thereby performing an installation positioning function.

Specifically, as shown in FIG8 , the raised portion 223 includes at least one partition plate 2231 disposed between the two spring conductive needles 42, and the partition plate 2231 separates the two spring conductive needles 42. In this embodiment, the raised portion 223 includes a plurality of partition plates 2231, and the plurality of partition plates 2231 form two mutually disconnected shunt portions 2230, and the two second through holes 225 are arranged in the two shunt portions 2230 at intervals. The advantage of this is that when the water tank 1 is taken out and placed, a small amount of water may drip onto the base assembly 2 and onto the spring conductive needle 42, and the two mutually disconnected shunt portions 2230 can avoid a short circuit between the two spring conductive needles 42, and even if the spring conductive needle 42 contacts water, the water is separated inside the two shunt portions 2230 and cannot contact, thereby preventing a short circuit between the two spring conductive needles 42 due to water conduction.

The spring conductive needle 42 is preferably made of copper. The middle frame 22, especially the partition plate 2231, is preferably made of a plastic material or other hydrophobic material, so that the water dripping onto the partition plate 2231 can quickly flow to the inside of the diversion part 2230 to avoid any possible conduction due to water.

Further, please continue to refer to Figures 5 and 8. At least two guide grooves 224 are also provided on one side of the middle frame 22 facing the water tank body 1. Here, one guide groove 224 is provided for each of the two diverter parts 2230, wherein one guide groove 224 is connected between one diverter part 2230 and the water inlet groove 221, and the other guide groove 224 is connected between the other diverter part 2230 and the atomizing groove 222. Moreover, the bottom surfaces of the two guide grooves 224 are preferably gradually lowered along the direction from the diverter part 2230 to the water inlet groove 221 and the atomizing groove 222, so as to timely guide the water in the diverter part 2230 to the guide groove 224 and the atomizing groove 222, so as to avoid excessive storage of water in the diverter part 2230. The raised portion 223 is preferably provided between the water inlet groove 221 and the atomizing groove 222.

Furthermore, the surfaces of the two conductive electrodes arranged on the first circuit board 31 can be gradually lowered in the direction away from each other, that is, even if moisture contacts the conductive electrodes along the spring conductive needle 42, it can flow downward in the direction away from each other, and will not cause moisture contact and short circuit, thereby further avoiding the occurrence of electrical contact hazards.

The second circuit board 41 can be set on the side of the middle frame 22 facing the bottom plate 21 by screw fixing or gluing, so the spring conductive needle 42 is sealed in the second through hole 225 by the sealant, so that the water in the diverter 2230 is completely blocked on the side of the middle frame 22 facing the water tank body 1, avoiding water from flowing downward and onto the second circuit board 41 through the second through hole 225, ensuring the electrical safety of the power supply component, the second circuit board 41, the fan component, etc. in the base component 2, and ensuring the operational safety of the air humidification device 100 and the personal safety of the user.

As shown in Figures 7 and 9, a mounting boss 125 is provided on the surface of the water tank bottom shell 12 facing the transparent light panel cover 5 corresponding to the recessed portion 123. This can prevent the water tank bottom shell 12 from being too thin due to the setting of the recessed portion 123, and ensure that the thickness of each part of the water tank bottom shell 12 can be roughly consistent, which is beneficial to ensuring the strength of the water tank bottom shell 12 and can also reduce the difficulty of manufacturing. For example, it is easier to fill the mold completely when the water tank bottom shell 12 is manufactured by injection molding.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
