[0020] Example 1

[0021] Reference Figure 1-4As illustrated, this embodiment provides a cup lid that is easy to assemble, including a top cover 100, an outer cover 200, and an inner cover 300. The inner cover 300 is inserted into the outer cover 200 from below to form an opening in the cup lid. The top cover 100 closes this opening from below and is assembled with the inner cover 300. The quick assembly without glue or welding is achieved through the snap-fit ​​structure between the top cover 100 and the inner cover 300, and between the outer cover 200 and the inner cover 300.

[0022] More specifically, the outer wall surface of the top cover 100 is provided with at least two hooks 101 arranged in a circumferential array, for example, three evenly distributed hooks. Each hook 101 includes a first guide surface 101a that is inclined downward and inward and a first contact surface 101b located above it. The bottom edge of the top cover 100 extends outward to form a pressing part for engaging with the flange 203 of the outer cover 200. Through their interaction, the top cover 100, the outer cover 200, and the inner cover 300 can be connected and fixed by fastening alone, without the need for glue or welding, which facilitates assembly.

[0023] The outer cover 200 is open at the top and bottom, and at least two horizontally symmetrical retaining strips 201 are provided on the inner wall, for example, two horizontally symmetrically distributed strips. The opening edge of the outer cover 200 is provided with an annular flange 203, which is used to form a sealing and pressing fit with the pressing part of the top cover 100. After the top cover 100 and the outer cover 200 are closed, they are pressed together by the outer edge of the top cover 100 against the flange 203.

[0024] The inner cover 300 includes a snap fastener 301 and a snap bar 302. The snap fastener 301 is disposed on the inner wall surface of the inner cover 300, and the snap bar 302 is disposed on the outer wall surface of the inner cover 300.

The second guide surface 301a is obliquely oriented upward and inward, and the second abutting surface 301b is disposed below the second guide surface 301a.

[0025] The engagement method between the locking strip 201 and the buckle strip 302 is the same as that between the buckle hook 101 and the snap fastener 301. That is, the locking strip 201 and the buckle strip 302 also have the same inclined guide surface and contact surface. The inner cover 300 is embedded in the outer cover 200 and is closed by the engagement of the locking strip 201 and the buckle strip 302. The top cover 100 closes the inner cover 300 downwards and is closed by the engagement of the buckle hook 101 and the snap fastener 301.

[0026] The top corner of the buckle 302 and the bottom corner of the retaining strip 201 are both guide bevels. The inner cover 300 is assembled upward from the lower opening of the outer cover 200. Under the action of the guide bevels, it is easy for the retaining strip 201 and the buckle 302 to slide into and engage. The hook 101 and the buckle 301 engage with each other; and the bottom corner of the hook 101 and the top corner of the buckle 301 are both guide bevels. The top cover 100 is assembled downward from the upper opening of the inner cover 300.

[0027] Example 2

[0028] In this embodiment, to achieve the positioning of the inner cover 300 embedded in the outer cover 200, the outer cover 200 includes a positioning protrusion 202, and the inner cover 300 includes a positioning groove 303. The positioning protrusion 202 is disposed on the inner sidewall of the outer cover 200, and the positioning groove 303 is disposed on the outer sidewall of the inner cover 300. The positioning protrusion 202 extends vertically, and the locking strip 201 extends circumferentially along the inner sidewall of the outer cover 200. The inner cover 300 is embedded in the outer cover 200 and positioned by the positioning protrusion 202 inserted into the positioning groove 303, thereby achieving radial positioning.

[0029] Furthermore, to improve the sealing performance of the cup lid in this embodiment, an inner lid sealing ring 304 is provided in the interlayer between the outer lid 200 and the inner lid 300, and a top lid sealing ring 204 is also provided between the top lid 100 and the outer lid 200. The interlayer between the outer lid 200 and the inner lid 300 is provided with an inner lid sealing ring 304, and a top lid sealing ring 204 is also provided between the flange 203 of the top lid 100 and the outer lid 200, so that the receiving cavity S forms a sealed space, preventing moisture from entering.

[0030] The lower side wall of the inner cover 300 is also fitted with a cup-mouth sealing ring 500 for sealing against the cup mouth. A groove is provided on the outer side wall of the inner cover 300, and the inner cover sealing ring 304 is fitted into the groove and seals against the inner side wall of the outer cover 200. A sealing groove is provided below the outer edge of the top cover 100, and the top cover sealing ring 204 is fitted into the sealing groove and seals against the side of the flange 203 of the outer cover 200.

[0031] Furthermore, in this embodiment, the cup lid also includes a smart component 400. The inner cover 300 has a mounting cavity S, in which the smart component 400 is installed sequentially from top to bottom. The smart component 400 includes a conductive film 401, a display screen 402, a circuit board 403, a battery 404, a temperature sensor 405, and a heat insulation component 406. During assembly, the positioning protrusion 202 and the positioning groove 303 are aligned and engaged. This structure can ensure the alignment of the buckle 301, the hook 101, the tail plug on the circuit board 403, and the through groove.

[0032] Specifically, the smart component 400 is housed within the mounting cavity S to prevent damage from moisture. From top to bottom, it includes electrically connected components. A touch-conductive film 401, tightly fitted to the top cover 101, is used for touch sensing; its transparent material allows the display screen 402 to be visible. The display screen 402 is integrated onto the circuit board 403 to display information such as temperature. Touching the top cover 101, through the touch-conductive film 401, transmits signals to the circuit board 403. Different touch gestures generate different signals, displaying different information, or enabling functions such as turning the screen on or off. The circuit board 403 also integrates a charging port (tail plug), its outer end passing through a slot in the inner cover 300 and a through hole in the outer cover 200. A temperature sensor 405 passes through the bottom wall of the inner cover 300 to sense the water temperature inside the cup. The mounting cavity S, located below the battery 404, is also equipped with a heat insulation component 406. The heat insulation component 406 is usually made of heat insulation material (such as foam material). In this embodiment, the mounting cavity S is provided with several support columns in the circumferential direction. The circuit board 403 is placed on the support columns and fixed by screws.

[0033] It should be noted that the purpose of this embodiment is to provide a quick and simple assembly structure for the outer cover 200, inner cover 300, and top cover 100. Through the snap-fit ​​design, a firm connection between the components can be achieved without the use of glue or welding, which significantly simplifies the assembly process. As for the functional implementation of the components, those skilled in the art can refer to existing technologies to implement them. For example, the touch function of the touch conductive film 401, how the display screen 402 displays information, the temperature detection of the temperature sensor 405, and other intelligent functions are all existing mature technologies. Similarly, this embodiment should also include the electrical connection of each electronic device of the intelligent component 400 and the arrangement of the circuit path. Those skilled in the art can also refer to existing mature technologies to implement them, so they will not be described in detail here.

[0034] This embodiment includes three assembly processes:

[0035] First, the inner cover 300 and the outer cover 200 are fastened together. The inner cover 300 is embedded into the outer cover 200, so that the fastening strip 302 and the locking strip 201 are horizontally aligned. By pressing upward, the fastening strip 302 is inserted into the groove of the locking strip 201, and at the same time, the positioning protrusion 202 is inserted into the positioning groove 303 to achieve radial positioning.

[0036] Second, the top cover 100 and the inner cover 300 are fastened together. The top cover 100 is placed downward to close the inner cover 300. The first guide surface 101a of the hook 101 contacts the second guide surface 301a of the buckle 301. Under pressure, the guide surface guides the hook 101 to deform elastically until the first contact surface 101b and the second contact surface 301b abut against each other and lock.

[0037] Thirdly, sealing and compression: an inner cover sealing ring 304 is provided in the interlayer between the outer cover 200 and the inner cover 300, and a top cover sealing ring 204 is provided between the top cover 100 and the outer cover 200. The pressing part of the top cover 100 presses the flange 203 downward, causing the sealing ring to deform under pressure, forming a waterproof seal.

[0038] In a preferred embodiment, the hook 101 and the buckle 301 are made of elastic material. For example, they can be integrally molded from POM plastic to enhance the durability of the fastening. The fastening surfaces of the clip 201 and the buckle 302 can also be provided with anti-slip textures to improve connection stability. The inner cover sealing ring 304 and the top cover sealing ring 204 are made of silicone to improve waterproof performance.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
