DETAILED DESCRIPTION

[0024] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0025] This embodiment provides a kettle, which is a specific application of the innovative solution of the utility model on a kettle. The innovative solution of the utility model can also be applied to containers such as water cups.

[0026] The kettle comprises a container cover and a kettle body, such as Figure 1-6 The container cover is arranged on the pot body, and the container cover comprises a cover body 100 and a water sealing seat 200 which can move up and down relative to the cover body 100, the cover body 100 has a water outlet channel 110, the water inlet of the water outlet channel 110 has an outer edge 111 and an inner edge 112, the water sealing seat 200 is provided with a sealing member 210, the sealing member 210 is in sealing contact with the outer edge 111 and the inner edge 112, a third sealing position is provided between the water sealing seat 200 and the cover body 100, a vent hole 220 is provided on the water sealing seat 200, and a chamber 221 which is in communication with the vent hole 220 is provided between the third sealing position and the inner edge 112.

[0027] A first sealing position is formed between the outer edge 111 and the sealing member 210, and a second sealing position is formed between the inner edge 112 and the sealing member 210. When the container cover is in a closed state, the first sealing position and the second sealing position can ensure that the water in the kettle body will not flow out from the water outlet channel 110. The third sealing position can prevent the water in the kettle body from flowing out from the matching gap between the water sealing seat 200 and the cover body 100, thus ensuring that the kettle will not leak. The chamber is located above the water sealing seat, and the upper and lower spaces of the water sealing seat at the corresponding position of the chamber are connected. The action surface of the gas in the kettle and the water sealing seat is reduced. When the pressure of the water sealing seat moving downward remains unchanged, the pressure increases, the water sealing seat is easier to move downward, and the container cover is easier to open. This structure also makes it easy for the container cover to be suitable for kettles of larger sizes. For example, the water sealing seat 200 with an original outer diameter of 45 mm is made into an outer diameter of 60 mm, and the container cover can still be opened relatively easily.

[0028] like Figure 3 As shown, the cover 100 is provided with a pressing assembly, and the water sealing seat 200 is connected to the pressing assembly, so that when the pressing assembly moves downward, the water outlet channel 110 opens. When the container cover is applied to a kettle, the water outlet channel 110 opens, and the water in the kettle can be poured out. Figure 5 As shown, an elastic member 300 is provided between the pressing assembly and the cover body 100 to make the pressing assembly tend to move upward or swing. In this way, under the action of the elastic member 300, the water outlet channel 110 can be kept in a closed state.

[0029] Further, the cover body 100 is detachably provided with an upper cover 400, and the upper end surface of the upper cover 400 is flush with the upper end of the cover body 100. This is conducive to the aesthetics of the container cover. In other optional embodiments, the upper surface of the upper cover 400 can also be lower or higher than the upper end of the cover body 100.

[0030] like Figure 3 , 5 As shown, the cover body 100 is provided with a water outlet, and there is a gap between the upper cover 400 and the side wall of the cover body 100. This facilitates the rotation and disassembly of the upper cover 400.

[0031] like Figure 2 , 3As shown in Figures 5 and 6, the pressing assembly includes a button 500 and a limiting member 600, the upper end of the elastic member 300 abuts against the limiting member 600, the lower end of the elastic member 300 acts on the cover body 100, the upper cover 400 is provided with a mounting hole 410, the pressing assembly is installed in the mounting hole 410, the lower end of the button 500 is provided with a driving tooth 510, the limiting member 600 is provided with a limiting portion 610, the limiting portion 610 is provided with an inclined surface 611, and a lower limiting groove 412 and an upper limiting groove 411 are provided on the side wall of the mounting hole 410. When the button 500 moves downward, the driving tooth 510 acts on the inclined surface 611 to drive the limiting member 600 to rotate, so that the limiting portion 610 switches between the lower limiting groove 412 and the upper limiting groove 411. When the container cover is in the closed state, the button 500 is pressed once, and the inclined surface of the driving tooth 510 on the button 500 contacts the inclined surface 611 on the limiting portion 610, so that the limiting portion 610 is separated from the upper limiting groove 411, and the limiting member 600 rotates, and the limiting portion 610 enters the lower limiting groove 412, and the container cover enters the closed state. Figure 3 The open state shown. Press the button 500 again, and the inclined surface of the driving tooth 510 contacts the inclined surface 611 on the limiting portion 610, so that the limiting portion 610 is disengaged from the lower limiting groove 412, and the limiting member 600 rotates, and the limiting portion 610 enters the upper limiting groove 411. When the container cover is in the open state, the container cover can be in the open state without pressing the button 500. In other optional embodiments, there may be no limiting member 600, and the water sealing seat 200 is directly fixedly connected to the button 500, and the container cover is kept in the open state by pressing the button 500.

[0032] like Figure 2 , 3 As shown in , 5, the water sealing seat 200 is provided with a connecting column 230, and the connecting column 230 is clamped with the limiting member 600; the cover body 100 is provided with a sealing ring 231, and the sealing ring 231 abuts against the connecting column 230 to form a third sealing position. The sealing ring 231 is elastic, so that the third sealing position can prevent water from flowing out from the matching gap between the cover body and the connecting column.

[0033] like Figure 3As shown, the middle part of the cover body 100 has a connecting part 120 connected to the upper cover 400, and the outer side of the side wall of the mounting hole 410 has a thread that is detachably connected to the inner side of the connecting part 120 through the thread. The lower end of the connecting part 120 has a bottom wall 121, and the sealing ring 231 is placed above the bottom wall 121. The sealing ring 231 is provided with a metal ring 122, and the lower end of the elastic member 300 abuts against the metal ring 122. The elastic member 300 is a spring, and the elastic force of the elastic member 300 not only makes the water sealing seat 200 tend to move upward, but also fixes the sealing ring 231, making the sealing ring 231 easier to install, and the metal ring 122 can protect the sealing ring 231.

[0034] Furthermore, the thickness of the inner end of the sealing ring 231 gradually decreases toward the connecting column 230. In this way, the contact surface between the sealing ring 231 and the connecting column 230 is small, which is conducive to reducing the friction between the sealing ring 231 and the connecting column 230, facilitating the up and down movement of the water sealing seat 200, making it easier to press.
