Provided is a negative-pressure steam-generating device facilitating cleaning of an inner cavity by disassembly. The device comprises a metal tank, a sealing ring, a bottom cover, a first vacuum valve, a second vacuum valve, a water inlet hose and an air exhaust metal tube and is characterized in that the outside of the metal tank is provided with a locating pin, and the interior of the metal tank is provided with an upper inner cavity; an opening of the upper inner cavity faces downward; a first metal tube and a second metal tube are arranged on the metal tank; the sealing ring is placed in a groove between the bottom cover and an inner ring; the bottom cover side is provided with a sealing buckle; one side of the sealing buckle is provided with an opening; the bottom cover and the inner ring are integrated as a whole; a lower inner cavity is formed in the middle between the bottom cover and the inner ring; one end of the first vacuum valve is connected with one end of the water inlet hose and the other end of the first vacuum valve is connected with one end of the first metal tube; the other end of the first metal tube is welded onto the metal tank; and the interior of the water inlet hose communicates with the upper inner cavity of the metal tank. The negative-pressure steam-generating device facilitating cleaning of the inner cavity by disassembly has the following beneficial effects: the metal tank and the bottom cover are easily closed in place; under effect of negative pressure, good closing effect is obtained; and the metal tank is conveniently separated from the bottom cover so that a user can conveniently clean scale in the metal tank.
Description
technical field [0001] The invention belongs to the field of steam generators, and in particular relates to a negative pressure steam generator which is convenient for disassembling and cleaning the inner cavity. Background technique [0002] Negative pressure steam refers to steam whose pressure is lower than atmospheric pressure and temperature is lower than 100°C. The application of this steam has been developed rapidly. However, the disassembly and assembly of the general steam generating container is cumbersome, and it is difficult to completely remove the internal scale by opening the steam generating container. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a negative pressure steam generating device which is convenient for disassembly and cleaning of the inner cavity. [0004] The embodiment of the present invention is achieved in this way, a negative pressure steam generating device that is easy to disassem...
