When the cover assembly 21 closes the water storage cavity 101, the cover assembly 21 is located on the limiting groove 106 and the limiting step 107. When the cover assembly 21 opens the water storage cavity 101, the cover assembly 21 is separated from the limiting groove 106 and the limiting step 107. By arranging the limiting assembly 14 on the front housing assembly 11 and at the opening of the water storage cavity 101, and the limiting assembly 14 and the front housing assembly 11 cooperate to form a limiting step 107 and also have a limiting groove 106, it is ensured that the flip cover assembly 2 installed at the opening of the water storage cavity 101 can be accurately installed in place, and there will be no over-insertion or position deviation due to vibration or movement, forming a good sealing structure to prevent the water in the water storage cavity 101 from leaking from the opening. At the same time, the limiting step 107 and the limiting groove 106 provide clear positioning and guidance for the flip cover operation, making the flip cover process faster and more accurate. In addition, it helps to disperse the force at the opening, improving the structural strength and stability of the entire front housing assembly 11 in the opening area. The design of the limiting step 107 and the limiting groove 106 can also be coordinated with the overall style of the water tank assembly, enhancing the overall texture of the coffee machine, thereby improving the user's satisfaction.

[0047] As Figure 2 and Figure 9 shown, in addition to the features of the above embodiments, this embodiment further defines that: the hook assembly 3 includes a support base 31 and a hook member 32. The housing assembly 1 is provided with a receiving groove 104. The support base 31 is arranged on the housing assembly 1 and located in the receiving groove 104, and the hook member 32 is arranged on the support base 31.

By arranging the hook member 32 on the support base 31, using the position of the support base 31, a hanging point is provided without occupying additional other space, making the working area or use environment cleaner and more orderly. At the same time, the support base 31 provides a stable structural support for the hook member 32, ensuring that the water tank assembly can be firmly placed on the coffee machine, providing a continuous water source for the coffee machine, ensuring the smooth completion of coffee making by the user, and enhancing the user's satisfaction.

[0048] As Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines that: the hook member 32 includes a clamping block 321 and a guiding block 322. The number of the clamping blocks 321 and the guiding blocks 322 is multiple. The multiple clamping blocks 321 are arranged on the support base 31, and the multiple guiding blocks 322 are arranged on the multiple clamping blocks 321. By arranging the multiple clamping blocks 321 on the support base 31, the structural strength of the support base 31 is increased, enabling it to better bear the weight and pressure of the placed items. By arranging the multiple guiding blocks 322 on the multiple clamping blocks 321, when the water tank assembly is placed at the position defined by the clamping blocks 321, the guiding blocks 322 can guide the water tank assembly to accurately and quickly enter the predetermined position, reducing the adjustment and groping during the placement process. When the water tank assembly enters the clamping position along the guiding blocks 322, it can reduce the direct friction and wear with the clamping blocks 321, protecting the surface of the item and the clamping structure.
