These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the position of these elements changes, the indication of these directions changes accordingly.

Referring to fig. 1 to 6, an air purifying humidifier according to an embodiment of the present utility model includes a housing 1, an air outlet assembly 2, a filter 4, a humidifying assembly 5, a movable assembly 9, and a water tank 14.

The shell 1 is provided with an air inlet 112, an air outlet 111 and a water return hole 31. The air outlet assembly 2 is disposed in the housing 1, and drives air to flow into the housing 1 from the air inlet 112 and flow out from the air outlet 111. The filter element 4 is arranged in the housing 1. The humidifying module 5 includes a humidifying member 51, the humidifying member 51 being provided on the housing 1, the humidifying member 51 being provided downstream of the filter member 4 in the air flow direction from the air inlet 112 to the air outlet.

The movable assembly 9 is movably connected to the housing 1, and the movable assembly 9 opens the water return hole 31 when in the first position and closes the water return hole 31 when in the second position. The water tank 14 is detachably connected to the housing 1 and forms a linkage with the movable assembly 9, when the water tank 14 is mounted on the housing 1, the movable assembly 9 is moved to the first position, and when the water tank 14 is detached from the housing 1, the movable assembly 9 is moved to the second position.

Wherein, the humidifying assembly 5 further comprises a water pump 52, when the water tank 14 is mounted on the housing 1, the water pump 52 conveys water in the water tank 14 into the housing 1 and sprays the water to the humidifying member 51, and water in the housing 1 can flow back to the water tank 14 through the water return hole 31.

Through the above structural design, when the water tank 14 is mounted on the housing 1, the movable assembly 9 is moved to the first position, and the water tank 14 links the movable assembly 9 to the first position and opens the water return hole 31. The water pump 52 feeds water in the water tank 14 into the casing 1, and sprays the humidifying member 51 to wet the humidifying member 51.

Air is driven by the air outlet assembly 2 to flow into the housing 1 through the air inlet 112 and out through the air outlet 111. In this embodiment, the air outlet assembly 2 includes a wind wheel and a motor for driving the wind wheel to rotate. The filter element 4 provided in the casing 1 has a filtering effect on air, and the humidifying element 51 humidifies air to increase the humidity of air. The residual water in the shell 1 flows back to the water tank 14 from the water return hole 31, so that the water is recovered.

When the water tank 14 is detached from the housing 1, the water tank 14 links the movable assembly 9 to the second position and closes the water return hole 31. The short circuit of circuit elements inside the air purifier caused by the outflow of redundant water in the shell 1 through the water return hole 31 is avoided.

Because the movable assembly 9 and the water tank 14 form linkage, the action accuracy of opening or closing the water return hole 31 is ensured, the water return hole 31 can be correctly opened under the working state of the air purification humidifier, and the water return hole 31 can be correctly closed when the water tank 14 is disassembled for water injection.

If the water return hole 31 is opened or closed by a separately operated element such as a solenoid valve, it is difficult to ensure high working stability due to the solenoid valve, and when the water tank 14 is detached from the housing 1, the solenoid valve still opens the water return hole 31, which may cause water in the housing 1 to overflow and short-circuit the circuit elements.

The shell 1 is divided into an air outlet cavity 11, a ventilation cavity 12 and a water storage cavity 13 from top to bottom in sequence, an air outlet 111 is formed in the top of the air outlet cavity 11, an air inlet 112 is formed in the side wall of the ventilation cavity 12, and a window 131 is formed in the side wall of the water storage cavity 13. The air purification humidifier also comprises a partition plate 3, wherein the partition plate 3 is arranged between the ventilation cavity 12 and the water storage cavity 13, and the water return hole 31 is arranged on the partition plate 3.
