Patent Searching and Data

Document Type and Number:
WIPO Patent Application WO/2018/019197
Kind Code:
A steam mechanism and steam apparatus. The steam mechanism comprises a water tank (200), a steam generator (300), and a gear pump (100). The gear pump (100) comprises a pump body (110), a water inlet pipe (120), an inner water outlet pipe (140), a water outlet opening (141) provided on the inner water outlet pipe (140), a sleeve valve (150), and an outer water outlet pipe (130). The use of the sleeve valve (150) by the gear pump (100) does not influence a normal operation of the gear pump (100), and addresses the issue of water leakage caused by a lack of complete sealing between the gears. The steam mechanism does not have high water quality requirements. A gap between the gears and the sleeve valve allows passage of fine dust particles, ensuring that the gear pump (100) can work normally even with poor water quality, and addressing the issue of a reciprocating pump malfunction caused by dust particles.
