In general, this type of electrical appliance utilizes a steam generating device to produce an instantaneous and large amount of water vapor.

However, it is known that a steam generator having a steam generating function can provide an instantaneous large amount of water vapor when used, but water vapor is often directly sent out after being generated, and not only water vapor cannot be uniformly dispersed, but also suddenly ejected water vapor is easily burned. Users are more dangerous to use.

The purpose of the novel is to provide a steam control valve with a structural innovation and a steam generator with better dispersion and safety.

The steam control valve of the present invention is suitable for connecting a steam generating chamber and a steam space, and comprises a valve seat, a steam control device installed inside the valve seat, and a first steam guide seat covering the valve seat. The valve seat has a control steam passage communicating with the steam generating chamber, and the steam control member can open and close the control steam passage, and the first steam guide seat has a plurality of first steam holes.

The beneficial effect of the present invention is that the cooperation of the above components not only can uniformly disperse water vapor, but also prevent water vapor from being instantaneously flushed out to improve safety during use.
