DETAILED DESCRIPTION

[0024] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0025] In a first aspect, the embodiments of the present application provide a sealing structure of a touch panel, mainly used in the top touch control panel area of a humidifier to achieve the effect of water vapor sealing. Figures 1 to 4 As shown in the figure, the sealing structure comprises a base 10, an annular sealing gasket 20, an inner cover 30 and an outer cover 50.

[0026] The top surface of the base 10 is provided with an annular boss 11. The base 10 is usually a part of the top shell of the humidifier, which provides a mounting base and support. The base 10 can be made of plastic or other materials with certain strength and rigidity to ensure the stability of the structure. On the top surface of the base 10, an annular boss 11 is provided, which is annular in structure and has a flat top surface for the subsequent installation of the annular sealing gasket 20.

[0027] The annular sealing gasket 20 is arranged on the top surface of the annular boss 11. The annular sealing gasket 20 is usually made of elastic material such as rubber, silicone, etc., and the shape and size of the annular sealing gasket 20 need to be accurately matched with the top surface of the annular boss 11 to form a tight sealing fit with the subsequent inner cover 30 and outer cover 50.

[0028] The inner cover 30 is installed on the base 10 and forms a mounting space 40 with the base 10, and the opening edge of the inner cover 30 is tightly pressed on the inner side area of the annular sealing gasket 20. Specifically, Figure 2 、 Figure 3 As shown in the figure, the mounting space 40 formed by the inner cover 30 not only facilitates the installation of the electric control board and other electrical devices of the humidifier, but also serves as a mounting support part for the display screen. The electric control board is fixed on the base 10 by screws, and the inner cover 30 is located above the electric control board. Specifically, the opening edge of the inner cover 30 is tightly pressed on the inner side area of the annular sealing gasket 20, forming the first line of defense for water vapor sealing, preventing water vapor from penetrating through the inner side gap.

[0029] The outer cover 50 is installed on the base 10 and located above the inner cover 30. The outer cover 50 and the inner cover 30 can be connected and fixed to the base 10 by screws, and the electric control board has a through hole for the position of the screw. The opening edge of the outer cover 50 is tightly pressed on the outer side area of the annular sealing gasket 20. Specifically, the outer cover 50 can serve as a touch control interface for the display screen, providing an operation interface for users. In order to achieve good cooperation with the inner cover 30 and the annular sealing gasket 20, the shape and size of the outer cover 50 are matched with the inner cover 30, and the opening edge of the outer cover 50 is tightly pressed on the outer side area of the annular sealing gasket 20, forming the second line of defense for water vapor sealing, which is complementary to the sealing structure of the inner cover 30, further improving the reliability of the sealing.

[0030] The first annular protrusion 12 is arranged on the top surface of the annular boss 11, and the annular sealing gasket 20 is provided with an annular sealing groove 21 matched with the first annular protrusion 12, and the groove wall of the annular sealing groove 21 is in sealing contact with the outer surface of the first annular protrusion 12.

[0031] When the humidifier is working, the annular sealing gasket 20 can ensure good sealing effect under the double effects of its own elastic deformation and the compression force of the inner cover 30 and the outer cover 50. In addition, the close cooperation between the first annular protrusion 12 and the annular sealing groove 21 further prolongs the penetration path of the water vapor, significantly enhances the reliability of the sealing structure, effectively prevents the penetration of water vapor, ensures the normal work of the touch panel, and ensures the safe and reliable operation of the electrical devices in the installation space 40, thereby prolonging the service life of the humidifier and improving the user experience.

[0032] In some embodiments, as shown in Figure 3 , Figure 4 , the outer side edge of the annular sealing gasket 20 is extended to form a sealing skirt 22, and the sealing skirt 22 is in sealing contact with the outer surface of the annular boss 11. The sealing skirt 22 forms another sealing with the outer surface of the annular boss 11, which further improves the reliability of the sealing structure on the basis of the double compression of the original inner cover 30 and the outer cover 50. In addition, the sealing skirt 22 can provide a certain guiding effect during assembly, helping the annular sealing gasket 20 to be installed more accurately in place.

[0033] In some embodiments, as shown in Figure 4 , the side of the sealing skirt 22 away from the annular boss 11 is in abutment with the inner surface of the outer cover 50. When the outer cover 50 is installed and compressed, the outer cover 50 will exert a pressure on the sealing skirt 22, so that the sealing between the sealing skirt 22 and the outer surface of the annular boss 11 is more tight, forming a more effective sealing, and also preventing dust, dirt and other sundries from entering between the inner cover 30 and the outer cover 50.

[0034] In some embodiments, as shown in Figure 4 , the inner surface of the inner cover 30 is provided with a second annular protrusion 31, and the inner cover 30 is compressed to the inner side area of the annular sealing gasket 20 through the second annular protrusion 31; the inner surface of the outer cover 50 is provided with a third annular protrusion 51, and the outer cover 50 is compressed to the outer side area of the annular sealing gasket 20 through the third annular protrusion 51. The design of the second annular protrusion 31 and the third annular protrusion 51 makes the compression force perpendicular to the annular boss 11 when the inner cover 30 and the outer cover 50 are installed and compressed, so as to prevent the annular sealing gasket 20 from slipping during use.

[0035] In some embodiments, as shown in Figure 4As shown, the end faces of the second annular protrusion 31 and the third annular protrusion 51 are provided with sealing protrusions 60, which are in sealing contact with the annular sealing gasket 20.

[0036] In some embodiments, as Figure 4 As shown, the first annular protrusion 12 is located at the inner side edge of the annular boss 11. By arranging the first annular protrusion 12 at the inner side edge of the annular boss 11, the path of water vapor penetrating from the outside to the inside can be effectively lengthened, that is, the water vapor must first pass through the part of the sealing skirt 22, the outer sealing gasket part, and then the inner sealing gasket part, to reach the inside, and arranging the annular boss 11 at the inner side edge can avoid structural interference between the protrusion and the outer cover 50.

[0037] In a second aspect, the embodiments of the present application provide a humidifier comprising the sealing structure of the touch panel of any one of the first aspect. Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the above-mentioned humidifier can refer to the corresponding process in the foregoing sealing structure of the touch panel, which will not be repeated here.

[0038] The sealing structure of the touch panel and the humidifier provided by the embodiments effectively enhance the reliability and stability of the sealing, significantly reduce the risk of water vapor penetrating into the inside of the humidifier, avoid the damage of internal electronic components due to moisture, prolong the service life of the product, and bring users a more comfortable and reliable use experience.
