[0062] A preferred embodiment is described below in conjunction with the accompanying drawings so as to make the present application more comprehensible and complete.

[0063] As Figures 1-4 shown, the present embodiment provides a lower door plate quick release structure 3 for connecting a tank 1 of a water purifier and a lower door plate 2.

[0064] The lower door plate quick release structure 3 comprises a switch piece (not shown in the figure), a magnetic piece 32 and a magnet limiting piece 33, the magnet limiting piece 33 is connected to the tank 1, the magnet limiting piece 33 has a first side 331 close to the lower door plate 2 and a second side 332 away from the lower door plate 2, and the thickness D of the magnet limiting piece 33 is greater than the thickness d of the magnetic piece 32.

[0065] The magnetic piece 32 is located inside the magnet limiting piece 33 and can move between a first position abutting the first side 331 and a second position abutting the second side 332.

[0066] The lower door plate 2 is provided with an opening hole 21, the first side 331 is provided with a first hole 333, and the opening hole 21 and the first hole 333 are through.

[0067] The switch piece can be arranged in the opening hole 21 and the first hole 333 to push the magnetic piece 32 from the first position to the second position.

[0068] When the magnetic piece 32 is located at the first position, the magnetic piece 32 can attract the lower door plate 2 by magnetic force;

[0069] When the magnetic piece 32 is located at the second position, the lower door plate 2 can be detached from the tank 1.

[0070] Thus, when the magnetic member 32 is located at the first position, the lower door plate 2 is attracted to the cabinet 1 by magnetic force; the maintainer inserts a switch member (which can be a screwdriver or other tool with a rod structure and commonly used by the maintainer) into the opening channel 21 and the first channel 333 to push the magnetic member 32 to the second position, so that the magnetic member 32 is away from the lower door plate 2, and the magnetic force acting on the lower door plate 2 is weakened to the extent that the lower door plate 2 can be detached from the cabinet 1. The above arrangement realizes quick detachment of the lower door plate 2, avoids the problem of key loss caused by using a traditional door lock, and meanwhile, the detachment of the lower door plate 2 requires the insertion of the switch member, which can avoid the non-maintainer from mistakenly opening the cabinet 1 and contacting the structure inside the cabinet 1, thereby ensuring safety.

[0071] In the embodiment, the lower door plate 2 is made of galvanized sheet, and the bent edges around the lower door plate 2 are welded and polished by argon arc welding to improve the strength and durability of the lower door plate 2. The surface of the lower door plate 2 is electroplated to make it beautiful and corrosion-resistant.
