Description

Mute type foaming device Technical Field The utility model relates to the technical field of coffee machines, in particular to a mute type foaming device. Background A steam system is arranged in the coffee machine, and the steam system comprises a steam generating device and a steam milk rod for ejecting steam. In general, a steam generating device is arranged in the coffee machine, and a steam milk bar is connected with the steam generating device and is suspended above a bearing surface outside the coffee machine so as to conveniently spray steam into a milk cup placed on the bearing surface. The steam milk stick is suspended outside the coffee machine, and the supporting force is small and the structural stability is low. In the process of conveying the high-pressure steam along the steam milk rod, the high-pressure steam can impact the steam milk rod, so that the steam milk rod vibrates to generate noise. In addition, when high-pressure steam is sprayed out of small-diameter spray holes on the steam milk stick and impacts milk, whistle can be generated. The noise generated by these steam milk sticks during operation greatly affects the user experience. It should be noted that the information disclosed in the above background section is only for enhancing understanding of the background of the present disclosure and thus may include information that does not constitute prior art known to those of ordinary skill in the art. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, an object of the present utility model is to provide a silent frothing device to reduce noise during frothing.
