As shown in fig. 1 to 7, a drawer device 1 according to an embodiment of the present invention includes a housing 100, a drawer 200, a transmission assembly, and a pressure relief device 600.

The housing 100 defines a receiving chamber 101 having one side opened. The drawer 200 is movably fitted in the receiving chamber 101, the drawer 200 is provided with a movable catch 300 to switch the drawer 200 between a locked state and an unlocked state, and the drawer 200 is provided with a locking member 210. The driving assembly is rotatably disposed on the drawer 200, and the locking member 210 is connected to the handle 300 through the driving assembly. The pressure relief device 600 is disposed at the pressure relief opening 201 of the drawer 200 and is adapted to cooperate with the transmission assembly.

Specifically, the driving assembly includes a swing member 410 and a driving lever 420, the swing member 410 is rotatably connected to the drawer 200 at a middle portion thereof, and one end of the swing member 410 is engaged with the buckle 300 and the other end thereof is engaged with the pressure relief device 600. The transmission rod 420 is connected to the latch member 210 and the swinging member 410. The transmission assembly thus controls both the operation of the locking element 210 and the operation of the pressure relief device 600.

When the drawer 200 is in the locked state, the locking member 210 is in clamping fit with the housing 100, and the swinging member 410 is disengaged from the pressure relief device 600, so that the pressure relief device 600 blocks the pressure relief opening 201, when the drawer 200 is in the unlocked state, the transmission assembly drives the locking member 210 to rotate so as to be disengaged from the housing 100, and the swinging member 410 stops against the pressure relief device 600 to drive the pressure relief device 600 to relieve pressure.

According to the drawer device 1 of the embodiment of the present invention, the casing 100 and the drawer 200 are provided, so that the drawer 200 is drawably fitted in the casing 100. Therefore, the user can take and place the articles by moving the drawer 200, and the operation convenience and comfort of the user are improved.

When the drawer 200 is in the locked state, the drawer 200 is snap-fitted to the housing 100 and the pressure relief device 600 blocks the pressure relief opening 201, so that a sealed space can be formed between the housing 100 and the drawer 200. Therefore, the sealing effect of the sealing space is improved, the storage performance of the drawer device 1 is realized, the functionality and the applicability of the drawer device 1 are improved, and the drawer 200 and the shell 100 can be reliably locked through clamping matching, so that the storage effect of the drawer device 1 is improved by improving the sealing effect between the drawer 200 and the shell 100.
