The present invention provides a detachable top cover 1 and an inner cover 2 with a snap-fit ​​assembly, and cooperates with detachable valve stem 5, inner plug 4 and other components, which can be disassembled by hand for cleaning without tools, thereby solving the hygienic problem of the traditional kettle cover being difficult to clean due to the inability to disassemble the integrated kettle cover, and greatly reducing the hygienic potential hazards from the structural root; and the components inside the kettle cover, such as the first and second reset components, adopt a detachable structure, so that consumers can replace fatigued or damaged springs separately without discarding the entire container cover; at the same time, the valve stem 5, the inner plug 4 and other components are provided with an exhaust structure that cooperates with each other, so that the exhaust channel and the water outlet channel 3 can be used to exhaust and release pressure at the moment the pressing handle 21 is pressed, so that the pressing handle 21 can be easily pressed down, and water vapor is prevented from spraying out, making it safer for consumers to use.

[0035] like Figure 2 and Figure 3As shown, the first reset assembly includes a first spring 9 and a first fixing buckle 10, the first spring 9 is installed on the upper end of the valve stem 5 through the first fixing buckle 10, one end of the first spring 9 is against the top surface of the inner cover 2, and the other end is against the first fixing buckle 10; the upper end of the valve stem 5 is provided with a guide groove 11 and a limit groove 12, the guide groove 11 extends downward along the axial direction of the valve stem 5 and then turns to be connected with the limit groove 12; the upper end of the guide groove 11 is provided with an opening, and the inner side of the first fixing buckle 10 is provided with a buckle 13 that matches the opening of the guide groove 11; during installation, the buckle 13 of the first fixing buckle 10 slides downward along the position of the opening of the guide groove 11 and rotates to The end of the limiting groove 12 allows the buckle 13 to be limited and fixed in the limiting groove 12, so that the first fixing buckle 10 is limited and fixed at the upper end of the valve stem 5; when disassembling, press the first fixing buckle 10 downward to withdraw the buckle 13 inside from the end of the limiting groove 12 of the valve stem 5; keep pressing, rotate the first fixing buckle 10 counterclockwise by 20°-30° (the specific angle needs to match the turning angle of the guide groove 11), so that the buckle 13 is aligned with the channel of the guide groove 11; and pull the first fixing buckle 10 upward along the guide groove 11, so that the first fixing buckle 10 can be disassembled, and the restriction on the first spring 9 can be released at the same time, so that the first spring 9 can be separated from the valve stem 5, and the disassembly is completed. After disassembly, the valve stem 5 is completely separated from the first spring 9, and the inner ring of the spring and the valve stem 5 can be directly washed, solving the problem of dirt hidden in the spring gap in the traditional integrated structure.

[0036] Among them, the working principle of the first reset component is: when the pressing handle 21 presses the valve stem 5 downward through the pressing lever 22, the first fixing buckle 10 moves downward synchronously with the valve stem 5 and compresses the first spring 9 to deform; when the user releases the pressing handle 21, the first spring 9 pushes the first fixing buckle 10 to reset upward through its own deformation reset, thereby driving the valve stem 5 connected to the first fixing buckle 10 to move upward and reset.

[0037] like Figure 2 and Figure 4As shown, the second reset assembly includes a second spring 14 and a second fixing buckle 15, and the second spring 14 is installed on the lower end of the valve stem 5 through the second fixing buckle 15, one end of the second spring 14 is against the top surface of the inner plug 4, and the other end is against the second fixing buckle 15; the valve stem 5 is provided with a guide inclined surface 16 and a limiting groove 17 located below the guide inclined surface 16 around the outer side, and an elastic limiting member 18 is provided on the inner side of the second fixing buckle 15 at a position corresponding to the limiting groove 17, one end of the elastic limiting member 18 is connected and fixed to the second fixing buckle 15, and the other end is a free end and is provided with a barb portion that is engaged with the limiting groove 17 19, the lower end surface of the barb 19 is provided with a guide portion 20 that is slidably matched with the guide slope 16; during installation, the guide portion 20 of the elastic limiter 18 slides downward along the guide slope 16 until the barb 19 is embedded in the limiting groove 17, so that the second fixing buckle 15 is limited and fixed at the lower end of the valve stem 5; during disassembly, the second fixing buckle 15 is pulled upward to make the barb 19 at the free end of the elastic limiter 18 elastically expand outward and thus disengage from the limiting groove 17, so that the second fixing buckle 15 can be disassembled, and the restriction on the second spring 14 is released at the same time, so that the second spring 14 can be separated from the valve stem 5, and the disassembly is completed. After disassembly, the valve stem 5 is completely separated from the second spring 14, and the inner ring of the spring and the valve stem 5 can be directly washed, solving the problem of dirt hidden in the spring gap in the traditional integrated structure.

[0038] Among them, the working principle of the second reset component is: when the pressing handle 21 presses the valve stem 5 downward through the pressing lever 22, the second fixing buckle 15 connected to the valve stem 5 moves downward (at this time, since there is still air pressure in the kettle, the inner plug 4 cannot be easily opened) and drives the first sealing ring 8 arranged at its end to open the exhaust channel for pressure relief; when the pressure in the kettle is relieved, the second fixing buckle 15 that moves downward compresses the second spring 14 to cause deformation. When the deformation reaches a certain degree, since the pressure in the kettle has been relieved, the second spring 14 pushes the inner plug 4 that is against it to move downward, thereby realizing the opening of the water outlet channel 3.

[0039] like Figure 1 and Figure 5As shown, the pressing assembly includes a pressing handle 21, a pressing lever 22 and a fixing bracket 23, one end of the pressing lever 22 is connected to the pressing handle 21, and the other end thereof is connected to the upper end of the valve stem 5; the pressing handle 21 is provided with a first rotating shaft 24, and the fixing bracket 23 is provided with a first shaft hole 25 matching the first rotating shaft 24, so that the pressing handle 21 rotates around the first rotating shaft 24; the pressing lever 22 is provided with a second rotating shaft 26, and the fixing bracket 23 is provided with a second shaft hole 27 matching the second rotating shaft 26, so that the pressing lever 22 rotates around the second rotating shaft 26; the pressing handle 2 A transmission column 28 is provided at the connection with the pressing lever 22. When the force-applying end of the pressing handle 21 is pressed downward, the pressing handle 21 rotates around the first rotation axis 24, so that the end of the pressing handle 21 connected to the pressing lever 22 drives the transmission column 28 to move upward; the upper end surface of the transmission column 28 contacts the lower end surface of the pressing lever 22, and the pressing lever 22 rotates around the second rotation axis 26 through the upward displacement of the transmission column 28, so that the end of the pressing lever 22 connected to the valve stem 5 is relatively displaced downward and the valve stem 5 is pressed to move downward, thereby driving the first sealing ring 8 to open the exhaust channel and driving the inner plug 4 to open the water outlet channel 3 in turn.

[0040] like Figure 5 As shown, an elastic reset member 29 is provided between the pressing handle 21 and the pressing lever 22, and the fixed end of the elastic reset member 29 is installed on the fixed bracket 23, and the free end thereof extends to the connection between the pressing handle 21 and the pressing lever 22. The positions of the pressing handle 21 and the pressing lever 22 are limited and fixed by the elastic reset member 29, so that the pressing handle 21 and the pressing lever 22 will not loosen, collide, or make abnormal noises due to shaking; wherein, the free end of the elastic reset member 29 is deformed when the pressing handle 21 is pressed, and when the pressing handle 21 is released, the elastic reset member 29 provides a restoring elastic force for the pressing handle 21 through its own deformation, thereby resetting the pressing handle 21.

[0041] like Figure 1 As shown, the inner cover 2 further includes a second sealing ring 30 , which is disposed at the lower end of the inner cover 2 , and the upper end surface of the inner plug 4 is sealed with the second sealing ring 30 , thereby closing the water outlet of the water outlet channel 3 .

[0042] like Figure 2 and 6 As shown, the snap-fit ​​assembly includes a spring buckle 31 and a snap-fitting groove 32. The spring buckle 31 is arranged on the edge of the inner cover 2, and the top cover 1 is provided with a snap-fitting groove 32 matching the spring buckle 31 at a position corresponding to the spring buckle 31. When disassembling the top cover 1 and the inner cover 2, the spring buckle 31 is pressed to force the spring buckle 31 to disengage from the snap-fitting groove 32, thereby separating the top cover 1 from the inner cover 2.

[0043] like Figure 7As shown, an alignment component is provided between the inner plug 4 and the inner cover 2, and the alignment component includes an alignment column 33 provided on the top surface of the inner plug 4, and an alignment groove 34 provided on the bottom surface of the inner cover 2 and corresponding to the alignment column 33 and cooperating with the alignment column 33. Through the precise cooperation of the alignment column 33 on the top surface of the inner plug 4 and the alignment groove 34 at the corresponding position of the bottom surface of the inner cover 2, the two can be quickly positioned and firmly docked, effectively avoiding the sealing failure or structural deformation caused by misalignment during the installation process, thereby significantly improving the assembly efficiency and reducing the difficulty of operation. At the same time, the anti-displacement ability between the inner plug 4 and the inner cover 2 is enhanced through the physical limiting effect, ensuring that the inner plug 4 can still maintain stable sealing performance in a vibrating or tilting environment; in addition, the guided matching structure can also reduce the friction loss when the inner plug 4 and the inner cover 2 are assembled, thereby extending the service life.

[0044] The traditional container cover cannot be disassembled, and the residual liquid or scale accumulated in the container cover cannot be cleaned, which may affect health if used for a long time. Therefore, the container cover and its internal parts of this embodiment are detachable. Figure 3 to Figure 4 As shown, when it is necessary to disassemble the container cover for cleaning or replacement of parts: first, press the spring buckle 31 to separate the top cover 1 and the inner cover 2; then, press the first fixing buckle 10 to disengage the first fixing buckle 10 from the limiting groove 12 and rotate the first fixing buckle 10 counterclockwise to slide and pull it out along the guide groove 11, so that the first fixing buckle 10 and the first spring 9 sleeved on the valve stem 5 can be disassembled; finally, the valve stem 5 is pulled out from the first through hole 6, and the second fixing buckle 15 is pulled upward to disengage the hook portion 19 of the second fixing buckle 15 from the limiting groove 17, so that the second fixing buckle 15 and the second spring 14 sleeved on the valve stem 5 can be disassembled, so that the valve stem 5 is taken out of the second through hole 7 of the inner plug 4, that is, the disassembly of the container cover is completed, and the container cover and its internal parts are cleaned one by one;

[0045] When the cleaning is completed and the container cover needs to be assembled: first, the valve stem 5 is inserted into the second through hole 7 of the inner plug 4, and the second spring 14 and the second fixing buckle 15 are installed and fixed in sequence; then, the upper end of the valve stem 5 is inserted into the first through hole 6 of the inner cover 2, and the alignment block of the inner plug 4 is aligned and inserted into the alignment groove 34 at the bottom of the inner cover 2; secondly, the first spring 9 and the first fixing buckle 10 are installed and fixed in sequence; finally, the top cover 1 and the inner cover 2 are fastened and fixed to each other through the fastening assembly, and the installation of the container cover is completed.
