| 摘要 |
The present invention provides a steam cleaning apparatus (100) comprising a water tank (10), a first valve (20) in fluid communication with a water tank (10) to allow air to flow into the water tank and prevent air and/or water from flowing out therefrom, an electrically powered air pump (30) in fluid communication with the first valve (20). A second valve (50) is in fluid communication with the outlet (16) of the water tank (10) and an inlet (42) of an electrically powered boiler (40). The second valve (50) is arranged to allow water above a first predetermined pressure to flow into the inlet (42) of the boiler and to prevent steam from flowing out therefrom, a steam cleaning head (60) in fluid communication with the outlet (44) of the boiler, and an on-off switch (70) having an“on”state for supplying electrical power to the air pump (30) and to the boiler (40) and an“off”state for preventing supply of electrical power to the air pump and to the boiler. |
