[0002] The working principle of a mobile air conditioner is to cool the hot air in the room through a condenser, condense the water into water droplets, and then collect them in a water tank. During the use of a mobile air conditioner, drainage needs to be considered. After a period of use, the condensed water inside needs to be discharged through the interface at the bottom. Usually, a detachable water tank is placed inside the air conditioner for easy drainage. When the water is full, the mobile air conditioner is shut down so that the water tank can be removed and the water can be poured out.

[0003] In the prior art, a floating magnet is usually arranged inside the water tank, and a magnetic sensing device adapted to the magnet is arranged outside the water tank. When the water is full, the magnet floats with the rising water level until it is within the sensing range of the magnetic sensing device. The magnetic sensing device outside the water tank senses the magnet, and then controls the motor to automatically cut off the power, and the mobile air conditioner is shut down.

Specifically, in this embodiment, the mounting protrusion 122 is a circular ring structure.

[0028] The top of the float 20 located outside the water tank body 10 is provided with a magnet 21 matched with a magnetic control switch 30, and the magnetic control switch 30 is electrically connected to the control circuit.

[0029] The float 20 includes a first mounting portion 22 and a second mounting portion 23 sequentially arranged along the height direction of the water tank body 10. The first mounting portion 22 is a disc-shaped, square-shaped, or elliptical structure, and the second mounting portion 23 is a hollow cylinder, a rectangular parallelepiped, or an elliptical structure. Specifically, in this embodiment, the first mounting portion 22 is a disc-shaped structure, and the second mounting portion 23 is a cylindrical structure.

[0030] The end face size of the first mounting portion 22 is larger than the aperture size of the mounting hole 12 , the aperture size of the second mounting portion 23 is matched with the aperture size of the mounting hole 12 , and the first mounting portion 22 is located between the water tank body 10 and the accommodating chamber, and the second mounting portion 23 is located inside the water tank body 10 .

The first through hole and the second through hole are both located directly below the magnetic control switch 30. The setting of the first through hole and the second through hole reduces the obstacle between the magnet 21 and the magnetic control switch 30, and improves the sensing accuracy of the magnetic control switch 30 to the magnet 21 when the float 20 floats up.

[0036] The working process of the detachable water tank 100 with full water alarm provided by the utility model is as follows: when the water in the water tank body 10 is full, the float 20 moves upward along the mounting hole 12 as the water level rises, and finally makes the magnet 21 at the top of the float 20 enter the sensing range of the magnetic control switch 30. The magnetic control switch 30 senses the existence of the magnet 21, and then transmits the full water signal to the control circuit, so that the control circuit controls the air conditioner body 201 to stop, and then the water tank body 10 can be drawn out to drain water.

[0037] Beneficial effect: When the water in the water tank body 10 is full, the float 20 rises along the hole wall of the installation hole 12 as the water level rises, and drives the magnet 21 to rise to within the sensing range of the magnetic control switch 30, so that the magnetic control switch 30 transmits a water full signal to the control circuit, and the control circuit controls the air conditioner body 201 to shut down. Since the magnet 21 is located at the end of the float 20 outside the water tank body 10, when the magnetic control switch 30 senses the magnet 21, there is no obstruction from the wall of the water tank body 10, thereby improving the detection accuracy.
