Abstract:
A dual-headed hand washing device having an anti-leak function, comprising liquid storage bottles (10), the tops of which are provided with liquid outlet holes (12) and air inlet holes (13), one-way inlet valves (14) being provided in the air inlet holes (13); a device head (20), connectedly affixed to the liquid storage bottles (10), and comprising a housing (21), the housing (21) being provided with two water outlets; a switch (51), arranged on the device head (20); sensors (70), arranged on a surface of the housing (21); a control circuit board (50), arranged inside the housing (21) and connected to the switch (51) and the sensors (70); micro-pumps (30), arranged inside the housing (21), connected to the control circuit board (50), and extending into the liquid storage bottles (10) by means of the liquid outlet holes (12); liquid extraction tubes (31), connected in one-to-one correspondence with the micro-pumps (30); and liquid outlet channels (40), arranged in between the micro-pumps (30) and the water outlets, there being two liquid outlet channels (40), and at least one liquid outlet channel (40) being provided with an atomizing nozzle (41). The provision of one-way inlet valves (14) in the air inlet holes (13) of the liquid storage bottles (10) of the present dual hand washing device prevents liquid in the liquid storage bottles (10) from leaking out from the air inlet holes (13) even if the hand washing device should fall over, thus preventing waste, and at the same time, preventing the liquid from corroding internal elements of the device head (20) and staining the exterior of the hand washing device.
