The mixing air inlet pipe 12 and the milk inlet pipe 13 are respectively connected to the first end of the mixing chamber 11, and air and milk can be input into the mixing chamber 11.

The constriction 111 can squeeze a mixture of steam, air and milk and release the pressure to form milk froth.

[0036] During operation, the milk froth outlet 14 is used to output hot milk or milk froth from the mixing chamber 11. When hot milk needs to be produced, the mixing air inlet pipe 12 can be closed by a valve to stop inputting air into the mixing chamber 11, and the milk can be heated by steam to form hot milk. When milk froth needs to be produced, the mixing air inlet pipe 12 can be opened by a valve to input air into the mixing chamber 11, and steam, air and milk are mixed to form milk froth in the mixing chamber 11.

[0043] The beneficial effect brought about by the above-mentioned implementation method is that the first rubber plug is provided to facilitate the cleaning of the mixing air intake pipe, and the second rubber plug is provided to facilitate the cleaning of the mixing chamber. The first rubber plug can guide and redirect the air flow through the steering air intake pipe, and after removing the first rubber plug, the steering part of the mixing air intake pipe can be cleaned, so that the milk foam generator is easy to clean.

[0044] In some implementations, the axes of the mixing chamber 11 and the mixing air intake pipe 12 are parallel to each other, one end of the steering air intake pipe 311 is connected to the mixing air intake pipe 12 , and the other end of the steering air intake pipe 311 is connected to the side wall of the mixing chamber 11 .

[0045] like Figure 1 As shown, the axes of the mixing chamber 11 and the mixing intake pipe 12 are parallel to each other, which improves the structural compactness of the mixing chamber 11 and the mixing intake pipe 12.

The first necking portion 141 and the second necking portion 142 are both used to eliminate larger bubbles in the milk froth, which can further improve the fineness of the milk froth and improve the use effect of the milk froth generator.

[0053] The beneficial effect brought about by the above implementation manner is that, by arranging the first constricted portion and the second constricted portion in the milk froth outlet, the fineness of the milk froth generated by the milk froth generator is further improved.

Figure 1 and Figure 3 As shown, structurally, a baffle 143 for guiding the lateral flow of hot milk or milk froth is provided at the end of the milk froth outlet 14. The baffle 143 can guide the hot milk or milk froth output from the milk froth outlet 14 to move laterally relative to the axis of the milk froth outlet 14, thereby preventing the hot milk or milk froth output from the milk froth outlet 14 from directly flowing out of the milk froth outlet 14, thereby improving the safety of the milk froth generator when in use.

[0056] The beneficial effect brought about by the above implementation manner is that it can prevent the hot milk or milk foam outputted from the milk foam output port from directly flowing out of the milk foam output port, thereby improving the safety of the milk foam generator when in use.
