## Abstract

A locking structure of a hot beverage machine with a steam sealing device is provided. The hot beverage machine has a feeder for various drinks placed with raw materials, such as coffee powder, coffee bag, tea leaves, tea bags, etc., and utilized with a sealing element, which allows steam to come in. When the machine is used, the feeder is tightly sealed with the sealing element so as to make drinks with purer flavor. Alternatively, when the machine is not in use for brewing, the feeder is separated from the sealing element with a distance such that the hot beverage machine can have a variety of different functions.

## Claims

### Claim 1

A locking structure of a hot beverage machine with a steam sealing device, wherein the steam sealing device provided in a front supporting base of said hot beverage machine comprising a first base, a second base, a feeder, and an assembly combined by a sealing element with a steam filter net, a connecting member, a guiding member, a joining member, a shifting member and a top cover;
characterized in that said locking structure of said steam sealing device of said hot beverage machine has horizontal sections respectively formed at ends of slopping guiding grooves on an outer surface of said guiding member combined with said connecting member so as to receive the protrusion on an inner surface of said shifting member to cause the guiding member to move downward to make a tight seal with the feeder on the bottom, and thus the protrusion moving into the horizontal section drives an engaging portion on the bottom of the guiding member to enter a corresponding boundary hole of the second base and serve as the locking device of the steam sealing device before steam is generated.
