[0028] See also Figure 1 and Figure 2 The embodiment of the present application provides a humidifier 100, which is used to generate and spray water mist to increase the air humidity around it. The humidifier 100 includes a water tank 10, a base 11, an operation panel 12 and a printed circuit board 13. The water tank 10 is used to store water. As a specific example, in this embodiment, the water tank 10 is roughly in the shape of a rectangular parallelepiped. In other embodiments, the water tank 10 can also be a cube, a cylinder or any other shape, which is not limited to this.

[0029] The base 11 is used to support the water tank 10. The base 11 and the water tank 10 together constitute the main structure of the humidifier 100. The base 11 includes a bottom plate 111 and a base shell 112 connected to the bottom plate 111. The bottom plate 111 is a plate structure at the bottom of the humidifier 100 when the humidifier 100 is normally placed and used. The base shell 112 is the main structure of the base 11. The base shell 112 and the bottom plate 111 can be connected by bolts or by the matching snap-fit ​​connection of a buckle and a slot. The specific connection method is not limited. The base shell 112 includes a receiving portion 113 and a control portion 114 connected to each other. The control portion 114 is bent relative to the receiving portion 113 to define a water tank installation space 115 for accommodating the water tank 10 together with the receiving portion 113. The control portion 114 is integrally formed and connected with the receiving portion 113. For example, the control portion 114 and the receiving portion 113 can be stamped or thermoplastic. The base 11 is provided with an inner cavity 116, and the inner cavity 116 is used to accommodate other structures and components of the humidifier 100. The control part 114 is provided with a mounting port 117 connected to the inner cavity 116, and the mounting port 117 is used to accommodate and install the operation panel 12. As a specific example, in the present embodiment, the base shell 112 composed of the receiving part 113 and the control part 114 is roughly "L"-shaped. In other embodiments, the base shell 112 can also be any other form. The operation panel 12 is connected to the base shell 112 and is located at the mounting port 117. The operation panel 12 can be operated by the user to adjust the working state / mode of the humidifier 100. The printed circuit board 13 is connected to the operation panel 12 and is located in the inner cavity 116. The operation panel 12 is electrically connected to the electronic components inside the humidifier 100 through the printed circuit board 13 to realize the control of the electronic components.

[0030] In the humidifier 100 provided in the present embodiment, since the printed circuit board 13 is arranged on the operation panel 12, and the operation panel 12 is installed at the installation port 117, when the operation panel 12 is installed, the printed circuit board 13 can also enter the inner cavity 116 from the installation port 117, and the installation is realized as the operation panel 12 is installed and fixed, so the base 11 does not need to be provided with a detachable side panel and a corresponding sealing and waterproof structure to meet the installation of the printed circuit board 13. Since the base 11 includes a bottom plate 111 and a base shell 112, and the base shell 112 includes an integrally formed receiving portion 113 and a control portion 114, the base shell 112 is an integrated structure, which has good structural strength and waterproof performance; and since the base shell 112 omits the detachable side panel and the corresponding sealing and waterproof structure, the structure of the base 11 can be simplified and the production and processing can be convenient. In summary, the humidifier 100 provided in the present embodiment has the advantages of a simple structure of the base 11, convenient production and processing, and good waterproof performance of the base 11.

[0031] In some embodiments, the control unit 114 includes a top plate 1141 and a first side plate 1142. As a specific example, in the present embodiment, the operation unit 122 is roughly a rectangular parallelepiped structure extending in the vertical direction. In other embodiments, the operation unit 122 can also be in any form such as a cube or a cylinder. The top plate 1141 is a plate structure at the top of the humidifier 100 when the humidifier 100 is normally placed and used. The top plate 1141 is relatively spaced from the bottom plate 111, the top plate 1141 is roughly parallel to the bottom plate 111, the first side plate 1142 is connected between the bottom plate 111 and the top plate 1141, and the first side plate 1142 is roughly perpendicular to the top plate 1141 / bottom plate 111. The first side plate 1142 is located on the side of the control unit 114 away from the water tank 10, a part of the mounting port 117 is located on the first side plate 1142, and another part is located on the top plate 1141. Through the above arrangement, since the operation panel 12 is arranged on the first side plate 1142 and the top plate 1141, and the first side plate 1142 is away from the water tank 10, the distance between the operation panel 12 and the water tank 10 can be increased to avoid the water vapor near the water tank 10 from invading the inside of the operation panel 12 as much as possible, thereby effectively protecting the safety of the operation panel 12.

[0032] See also Figure 2 and Figure 3In some embodiments, the operation panel 12 includes a mounting portion 121 and an operating portion 122 connected to each other. As a specific example, in this embodiment, the mounting portion 121 and the operating portion 122 are both substantially plate-shaped structures, and the two are substantially perpendicular to each other. In other embodiments, the mounting portion 121 and the operating portion 122 can also be any other morphological structure, and the connection form between the two is not limited. The mounting portion 121 is arranged at the portion where the mounting port 117 is located on the top plate 1141, and is detachably connected to the top plate 1141. The mounting portion 121 and the top plate 1141 can be connected by fasteners such as bolts, or by a clamping structure, and the specific connection method is not limited. The operating portion 122 is arranged at the portion where the mounting port 117 is located on the first side plate 1142, and is detachably connected to the first side plate 1142. The connection between the operating portion 122 and the first side plate 1142 can be connected by fasteners such as bolts, or by a clamping structure, and the specific connection method is not limited. A touch screen 123 is provided on the side of the operating part 122 facing away from the inner cavity 116, and the user can operate the humidifier 100 through the touch screen 123. The printed circuit board 13 is connected to the side of the operating part 122 facing the inner cavity 116, and is electrically connected to the touch screen 123. The printed circuit board 13 and the operating part 122 can be connected by fasteners such as bolts, and can also be connected by a snap-fit ​​structure. The specific connection method is not limited. Through the above arrangement, the operating part 122 and the mounting part 121 can be installed and connected with the first side plate 1142 and the top plate 1141 from two different directions, thereby improving the stability of the connection between the operating panel 12 and the base shell 112; in addition, since the touch screen 123 is arranged on the first side plate 1142, the touch screen 123 is located on the side of the operating part 114 facing away from the water tank 10, which can reduce the influence of water vapor around the water tank 10 on the touch screen 123, thereby improving the user experience.

[0033] See also Figure 3 In some embodiments, the mounting portion 121 is provided with a clamping member 124, and at least a portion of the structure of the clamping member 124 is spaced apart from the mounting portion 121 to form a slot 125. For example, the clamping member 124 may be a hook or claw disposed on the mounting portion 121, one end of the clamping member 124 is connected to the mounting portion 121, and the other end is bent relative to the mounting portion 121 and spaced apart from the mounting portion 121, thereby forming the slot 125. The top plate 1141 is provided with a matching member 1144, and the matching member 1144 may be a block or strip disposed on the top plate 1141 and corresponding to the clamping member 124, and at least a portion of the structure of the matching member 1144 is accommodated in the slot 125 and clamped with the clamping member 124, so as to limit the movement of the operation panel 12 in a direction perpendicular to the top plate 1141. Through the above arrangement, the snap-fitting member 124 and the matching member 1144 form a snap-fitting structure, which can enable the display control panel to move in a direction perpendicular to the top plate 1141 , so as to improve the stability of the connection between the control panel and the base housing 112 .

[0034] See also Figure 4 In some embodiments, a plurality of ribs 14 are provided on one side of the first side plate 1142 facing the inner cavity 116. The plurality of ribs 14 are parallel to each other and arranged at intervals. The ribs 14 are connected to the first side plate 1142, and the extending direction of the ribs 14 is substantially perpendicular to the top plate 1141. The ribs 14 can enhance the bending resistance of the first side plate 1142, thereby improving the structural strength of the base shell 112, and avoiding deformation of the base shell 112 as much as possible, so as to improve the overall stability of the base 11.

[0035] See also Figure 5 In some embodiments, the operation panel 12 protrudes relative to the surface of the base shell 112, and the height of the operation panel 12 protruding relative to the surface of the base shell 112 is greater than or equal to 5 mm. The protrusion of the operation panel 12 relative to the surface of the base shell 112 means that the mounting portion 121 protrudes relative to the top plate 1141, and the operation portion 122 protrudes relative to the first side plate 1142. In addition, the height of the protrusion of the mounting portion 121 relative to the top plate 1141 can be the same as or different from the height of the protrusion of the operation portion 122 relative to the first side plate 1142. Through the above arrangement, the adverse effect of the assembly gap step difference of the operation panel 12 on the appearance can be weakened. Since the operation panel 12 is provided with a protruding structure, during the assembly process of the operation panel 12, the assembly accuracy requirement is low, which is convenient for installation. At the same time, the production accuracy requirement of the operation panel 12 is also reduced, which can reduce the production cost. In this embodiment, since the operation panel 12 is configured to protrude relative to the surface of the base shell 112, during the assembly process, even if there is an assembly error, the operation panel 12 is in a shape of protruding as a whole relative to the surface of the base shell 112, thereby improving the aesthetic appearance of the humidifier 100.

[0036] See also Figure 1 , Figure 5 and Figure 6In some embodiments, the receiving portion 113 includes a receiving plate 1131 facing the water tank installation space 115, the water tank 10 is arranged on the receiving plate 1131 and is located in the water tank installation space 115, and the water tank 10 is supported by the receiving plate 1131. As a specific example, in this embodiment, the receiving portion 113 is a roughly rectangular parallelepiped structure extending in the horizontal direction. In other embodiments, the receiving portion 113 can also be a three-dimensional structure of any other form such as a cube. The receiving plate 1131 is arranged on the top of the receiving portion 113, and the water tank 10 is arranged above the receiving portion 113. The water tank 10 contacts the receiving plate 1131 and is supported by the receiving plate 1131. In some embodiments, a positioning member 15 is provided on the receiving plate 1131, and a positioning groove 16 adapted to the positioning member 15 is provided on the water tank 10. When the water tank 10 is placed on the receiving plate 1131, the positioning member 15 is inserted into the positioning groove 16 and at least part of the structure of the positioning member 15 is in contact with the inner wall of the positioning groove 16 to limit the movement of the water tank 10 on the receiving plate 1131, thereby improving the stability of the connection between the water tank 10 and the receiving portion 113.

[0037] In some embodiments, the control part 114 is integrally connected with the receiving plate 1131, for example, the control part 114 and the receiving plate 1131 can be stamped or thermoformed. Specifically, the second side plate 1143 is integrally connected with the receiving plate 1131, and the second side plate 1143 is substantially perpendicular to the receiving plate 1131. The surface of the water tank 10 facing the control part 114 is provided with a protrusion 101, the protrusion 101 protrudes relative to the surface of the water tank 10, and the protrusion 101 abuts against the surface of the control part 114 to separate the water tank 10 from the control part 114. As a specific example, in this embodiment, the protrusion 101 is an annular frame arranged around the edge of the surface of the water tank 10 facing the control part 114, which is not only used to separate the water tank 10 from the control part 114, but also can improve the structural strength of the water tank 10. In other embodiments, the protrusion 101 may also be a structure of any shape protruding from the water tank 10 toward the surface of the control unit 114, such as a columnar structure or a block structure, which is not limited to this. Due to the provision of the protrusion 101, the side wall of the water tank 10 and the second side plate 1143 of the control unit 114 cannot be completely fitted together, and there is a certain space between the water tank 10 and the control unit 114. The space is the space between the water tank 10 and the control unit 114.

[0038] In some embodiments, a receiving groove 1132 is provided on the receiving plate 1131. The receiving groove 1132 can be a groove body formed by directly bending and concave the receiving plate 1131, or a groove body directly opened on the surface of the receiving plate 1131. The receiving groove 1132 is provided with other components of the humidifier 100 such as an atomization component (not shown in the figure). A matching portion 102 corresponding to the receiving groove 1132 is provided on the water tank 10. The matching portion 102 protrudes relative to the surface of the water tank 10, and the matching portion 102 is embedded in the receiving groove 1132. Through the above arrangement, the receiving groove 1132 and the matching portion 102 form a snap-fit ​​structure to realize the connection between the water tank 10 and the receiving portion 113, and then matched with the positioning column and the positioning groove 16 to further improve the stability and reliability of the connection between the water tank 10 and the receiving portion 113.

[0039] In some embodiments, an inner chamfer (not shown) is provided at the opening of the receiving groove 1132, and an outer chamfer (not shown) is provided at the periphery of the matching portion 102, and the inner chamfer fits the outer chamfer. Through the above configuration, the configuration of the inner chamfer and the outer chamfer can facilitate the installation of the matching portion 102 into the receiving groove 1132, so as to facilitate the user to re-install and connect the water tank 10 with the receiving portion 113 after disassembling the water tank 10.

[0040] In summary, in the humidifier 100 provided in this embodiment, since the printed circuit board 13 is arranged on the operation panel 12, and the operation panel 12 is installed at the installation port 117, when the operation panel 12 is installed, the printed circuit board 13 can also enter the inner cavity 116 from the installation port 117, and the installation is realized as the operation panel 12 is installed and fixed, so the base 11 does not need to be provided with a detachable side panel and a corresponding sealing and waterproof structure to meet the installation of the printed circuit board 13. Since the base 11 includes a bottom plate 111 and a base shell 112, and the base shell 112 includes an integrally formed receiving portion 113 and a control portion 114, the base shell 112 is an integrated structure, which has good structural strength and waterproof performance; and since the base shell 112 omits the detachable side panel and the corresponding sealing and waterproof structure, the structure of the base 11 can be simplified and the production and processing can be convenient. In summary, the humidifier 100 provided in this embodiment has the advantages of a simple structure of the base 11, convenient production and processing, and good waterproof performance of the base 11.
