Technical Field

[0001] This utility model relates to the field of drinking appliance technology, and in particular to a cup lid assembly with pressure relief function and its boiling cup. Background Technology

[0002] With technological advancements and improved living standards, electric water cups are increasingly used in various scenarios. Existing electric water cups typically consist of a lid and a body, with a heating element inside to heat the water. When heating water, the inside of the cup cannot be sealed; otherwise, the water vapor inside will gradually increase as the water temperature rises, leading to increased internal pressure and potential safety hazards.

[0003] Chinese utility model patent, publication number CN212234169U, discloses a lid assembly for an electric kettle, including an upper lid and an outer lid. The lid assembly has an airflow channel for venting or venting air, which communicates with the inner liner of the electric kettle. The upper lid has a vent for connecting outside air to the airflow channel. The lid assembly also includes a waterproof and breathable membrane to prevent liquid leakage, which is disposed within the airflow channel. When the electric kettle boils water, water vapor in the inner liner is discharged to the outside of the kettle through the waterproof and breathable membrane of the airflow channel and the vent. After boiling, the water in the inner liner gradually cools down, and outside air enters the inner liner through the vent and the waterproof and breathable membrane of the airflow channel. This utility model allows for water heating without opening the lid; however, the lid still needs to be removed before drinking, making it inconvenient to use.

[0004] Therefore, in order to eliminate the need to remove the lid when boiling or drinking water, achieving the goals of safely boiling water with the lid closed and easily drinking water without opening the lid, existing kettles need further improvement. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] use Figure 1 This paper describes a cup lid assembly with a pressure relief function. Figure 1 This is a schematic diagram of the cup lid assembly of this utility model. This pressure-relieving cup lid assembly can be used in drinking containers, such as drinking cups or kettles. The following description only focuses on the application scenario of the pressure-relieving cup lid assembly in a kettle; applications of the pressure-relieving cup lid assembly in other types of cups will not be discussed further.

[0043] First, use Figures 2-4 The overall structure of this cup lid assembly with pressure relief function is described. Figure 2 This is a cross-sectional view of the cup lid assembly of this utility model. Figure 3 This is one of the exploded cross-sectional views of the cup lid assembly of this utility model. Figure 4 This is the second exploded cross-sectional view of the cup lid assembly in this utility model.

[0044] The pressure-relief cup lid assembly includes a cup lid base 1, a flip-top body 2, and a venting assembly 3, wherein:

[0045] The bottom of the lid base 1 can be installed on the mounting mouth 7 at the top of the kettle body 6. The middle of the lid base 1 is provided with a drinking port 101 that passes through the lid base 1. The drinking port 101 is connected to the internal water storage cavity of the kettle body 6. Users can drink water stored inside the kettle body 6 through the drinking port 101 or drink water through the drinking port 101.

[0046] The flip-top body 2 is roughly cylindrical in shape and is located on the top of the cup lid base 1. One end of the flip-top body 2 is rotatably mounted on the cup lid base 1. When the flip-top body 2 is rotated downwards, it can cover and be mounted on the drinking spout 101.

[0047] A venting component 3 can be installed on the flip-top body 2 to achieve pressure relief and ventilation. Specifically, the venting component 3 includes a vent 301 and a waterproof and breathable membrane 302. The waterproof and breathable membrane 302 is a high-molecular-weight breathable film (expanded polytetrafluoroethylene e-PTFE). The vent 301 is opened onto the flip-top body 2 and connected to the drinking spout 101. The waterproof and breathable membrane 302 is installed at the bottom of the vent 301. The hot air generated inside the kettle body 6 can be discharged along the drinking spout 101, the waterproof and breathable membrane 302, and the vent 301. The waterproof and breathable membrane 302 also has a waterproof function, preventing water inside the kettle body 6 from leaking to the outside of the flip-top body 2. Therefore, when boiling water in the kettle body 6, it is not necessary to disassemble the lid base 1 or rotate the flip-top body 2 to complete the boiling process.

[0048] In this implementation plan, during use, refer to Figure 6 and Figure 7 The lid base 1 is installed onto the kettle body 6. When the flip-top 2 is in the closed position of the lid base 1, during the boiling process, the hot air generated by the kettle body 6 can pass through the waterproof and breathable membrane 302 and be discharged to the outside of the lid base 1 through the vent 301 and the waterproof and breathable membrane 302, ensuring the safe use of the kettle body 6. Therefore, the kettle body 6 can boil water without removing the lid base 1 or opening the flip-top 2. Furthermore, by rotating the flip-top 2, the drinking spout 101 can be closed or opened through the cooperation of the lid base 1 and the flip-top 2. When drinking water, the user does not need to remove the cup lid base 1 from the cup body 6. They only need to rotate the flip cover 2 to drink water through the drinking spout 101. This achieves the purpose of eliminating the need to remove the cup lid base 1 when drinking water, making it more convenient and easier for the user to drink water.

That is, the power switch 401 can be pressed down. In order to achieve the reset function after the power switch 401 is pressed down, a reset spring is provided between the power switch 401 and the mounting groove 102. The reset spring is a compression spring, which enables the power switch 401 to reset after being pressed down.

[0058] The locking fastener 402 is installed on one end of the flip cover 2. The top of the switch 401 has a locking groove 403 that matches the locking fastener 402, and the locking fastener 402 can be locked together with the locking groove 403. In this embodiment, the flip cover 2 and the cup lid base 1 can be locked together by the mutual locking between the switch 401, the locking fastener 402 and the locking groove 403. At the same time, the breathable membrane support 303 and the silicone sleeve 306 can be stably sealed to the drinking spout 101, preventing water leakage from the drinking spout 101.

[0059] In some embodiments, such as Figure 3 and Figure 4 As shown. Figure 3 This is one of the exploded cross-sectional views of the cup lid assembly of this utility model.
