It can be understood that under the condition that the kettle 1 is placed in the body 3, as shown in Figure 2 and Figure 5 The docking port 121 is opened to be in close communication with the water inlet 73 of the body 3; under the condition that the kettle 1 is placed alone, as shown in Figure 4 The docking port 121 is closed to prevent the liquid in the kettle 1 from leaking.
[0033] In some embodiments, as shown in Figure 2As shown, the mounting section 13 comprises a communicating sub-section 131 and a limiting sub-section 132, the communicating sub-section 131 is located between the extending section 12 and the limiting sub-section 132, and the communicating sub-section 131 is adapted to pass through the side wall of the kettle 1, so that the extending section 12 protrudes outside the kettle 1 to facilitate the communication with the machine body 3. The limiting sub-section 132 is located inside the kettle 1, and the radial dimension of the limiting sub-section 132 is greater than that of the communicating sub-section 131, so as to limit the installation.
[0034] The further check valve 2 further comprises a fixing member 30, which is sleeved on the outer periphery of the communicating sub-section 131 or the extending section 12, and the radial dimension of the fixing member 30 is greater than that of the communicating sub-section 131, so that the side wall of the kettle 1 is clamped between the limiting sub-section 132 and the fixing member 30, and the check valve 2 is detachably mounted on the kettle 1, so as to facilitate the disassembly and cleaning or replacement of the check valve 2.
[0035] In at least one embodiment, as shown in Figure 2 , a sealing gasket 40 is arranged between the fixing member 30 and the side wall of the kettle 1, and between the limiting sub-section 132 and the side wall of the kettle 1, so as to further improve the sealing performance of the check valve 2 mounted on the kettle 1, and facilitate the prevention of liquid leakage.
[0036] In some embodiments, as shown in Figure 2 , Figure 4 , and Figure 5 , the inner wall of the extending section 12 is tapered, so that the docking interface 121 gradually expands from one end close to the cavity 11 to the other end away from the cavity 11, so as to guide the docking of the machine body 3 and the check valve 2, and improve the convenience of placing the kettle 1 on the machine body 3.
