A steam cleaner with double water pumps

Abstract

The invention discloses a steam cleaner with double water pumps. The steam cleaner comprises a handle, a steam generating device and a cleaning head; the steam generating device comprises an upper shell and a lower shell, and is provided with a switch button; a water tank is arranged in the upper shell, a first water pump, a second water pump, a heating body and a steam outlet are arranged in the lower shell; the input end of the first water pump is connected with the water tank through a first passage pipe, and can pump water to the inside of the heating body to heat, the output end of the first water pump is connected with the heating body by a second passage pipe; the input end of the second water pump is communicated with the second passage pipe through a third passage pipe, the output end of the second water pump is communicated with the first passage pipe through the fourth passage pipe, and is finally communicated with the water tank; the second water pump starts working after the switch button is pressed to stop the heating body from working, and pumps steam in the heating body back into the water tank. When the heating body stops working, the second water pump can pump residual steam in the heating body into the water tank, and recycle the steam, so that the steam cleaner is high in safety, energy-saving, and environmental friendly.

Description

technical field [0001] The invention relates to a steam cleaner, in particular to a steam cleaner with double water pumps.

Problems solved by technology

And when the user presses the switch button to stop the heating element, the water vapor remaining in the heating element will continue to spray out, and it will take a while to completely stop the steam spraying. Generally, it is difficult to stop the steam within 3 seconds. It complies with the relevant national safety regulations, and the temperature of the steam is very high, which poses a threat to the personal safety of users, especially young children. There are relatively large safety hazards and accidents are prone to occur
