Description

Steam generating device and garment steamer Technical Field The present invention relates to, but is not limited to, a steam generating device and garment steamer. Background As the requirements of people on clothes ironing are higher and higher, the requirements on the steam generating performance of the garment steamer are higher and higher. Good ironing effect requires a larger steam jet speed, which has a certain positive correlation with the steam jet noise, i.e. the large jet speed improves the jet noise to a certain extent, thereby affecting the use experience of the product. Disclosure of Invention The embodiment of the invention aims to provide a steam generating device and a garment steamer, which can reduce the use noise of the garment steamer and improve the use experience of the garment steamer. The technical scheme of the embodiment of the invention is as follows: A steam generating device, comprising: a steam generator having a steam generating chamber arranged to heat water or steam, the steam generating chamber having a steam injection port; A muffler having a muffler chamber, the muffler chamber being in communication with the vapor injection port, and The panel is covered at the outlet end of the silencing cavity, and is provided with a steam spray hole communicated with the silencing cavity.
