[0006] The purpose of the utility model can also be optimized by adopting the following technical measures.

[0007] Preferably, a cavity is provided on the end face of the knob close to one end of the rotating shaft, the cavity is higher than the end face, a positioning column is provided in the cavity, a spring is passed through the positioning column, the head of the positioning column can protrude out of the cavity to a limited extent, and the retaining ring is provided with a concave surface corresponding to the head of the positioning column and a limit block for supporting the protruding surface of the cavity. When the rotating shaft is inserted into the hollow channel and the knob is rotated to achieve installation on the fixed ring, the positioning column enters into the concave surface as the rotating shaft rotates, and the protruding part of the cavity is limited by the limit block and cannot continue to rotate.

[0008] Preferably, when the rotary valve is mounted on the assembly shell, a spacing is provided between the knob and the assembly shell.

[0009] Preferably, the installation blocks are symmetrically arranged, and a slope is provided on a portion of an end surface of the installation block close to the knob.

[0010] After adopting the above technical solution, the switching component of the utility model is designed to be detachable, which allows customers to remove and clean it after whipping the milk foam, reducing the situation of mildew caused by incomplete cleaning of the remaining milk liquid and improving the usability of the product.

[0019] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0020] Combined with Figure 6 , a detachable rotary valve 3 for the milk box foaming structure includes a knob 31, a rotary shaft 32, a fixed ring and an assembly shell 6. The fixed ring is axially provided with a hollow channel, and the inner end of the fixed ring is provided with a buckle. The assembly shell 6 is provided with an installation hole 613 for installing the fixed ring. When the inner end of the fixed ring is inserted into the installation hole 613, it is fixed by hooking the buckle around the installation hole 613. The rotary shaft 32 is provided with installation blocks 33, the installation blocks 33 are symmetrically arranged, and a bevel is provided on the upper part of one end surface of the installation block 33 close to the knob 31.

[0021] Combined with Figures 1 to 3A retaining ring 61 is provided in the hollow channel at the outer end of the fixed ring. The retaining ring 61 is provided with a notch. When the rotating shaft 32 is inserted into the hollow channel, the mounting block 33 passes through the notch. Then the knob 31 is rotated. The mounting block 33 is staggered with the notch to achieve the installation of the knob 31 on the fixed ring. When the rotary valve 3 is installed on the assembly shell 6, a certain distance is provided between the knob 31 and the assembly shell 6.
