In one embodiment, referring to fig. 1-3, an automatic latch includes a moving part 100, a drive assembly 200, a detection assembly 300, and a control board 400.
The moving part 100 may be a locking tongue or the like.
The driving assembly 200 is connected to the moving member 100, and drives the moving member 100 to move, thereby locking and unlocking the lock.
The detecting assembly 300 is used for detecting the opening and closing state of the cover of the liquid nitrogen tank and detecting the locking state of the moving part 100.
The control board 400 is connected to the detection unit 300, and can receive detection information such as the open/close state of the cover of the liquid nitrogen tank and the lock state of the moving member 100, which are detected by the detection unit 300.
Meanwhile, the control board 400 is further connected to the driving assembly 200, and further controls the driving assembly 200 to drive the moving member 100 according to the opening and closing state of the cover of the liquid nitrogen tank, the locking state of the moving member 100, and the like, which are detected by the detecting assembly 300, so as to realize the automatic locking of the lock.
Therefore, the present embodiment can automatically lock the can lid while closing the can lid, thereby reducing the complexity of the operation.
Specifically, when the tank cover of the liquid nitrogen tank is closed and needs to be locked, the detection assembly 300 detects that the tank cover is in a closed state and the moving part 100 is in an unlocked state, and then transmits detection information to the control board 400. The control board 400 controls the driving assembly 200 to drive the moving part 100 to perform the locking movement until the locking is completed.
Further, the control board 400 can be used to receive a control signal when the unlocking is required, and control the driving assembly 200 to drive the moving component 100 to perform the unlocking movement until the unlocking is completed.
As an example, when the lock needs to be unlocked, the user may perform authentication through authentication methods such as digital password authentication or fingerprint authentication.

When the can lid is opened, i.e., the can lid is separated from the can body, the object 310 is away from the first detector 320 and is not detected by the first detector 320. When the can lid is closed with the can body, the object 310 reaches the detection range of the first detector 320, and is detected by the first detector 320.
Thus, the first detector 320 determines the open/close state of the tank cover based on the detection of the object 310.
As an example, the object under test 310 may be provided as a magnet, and the first detector 320 may be provided as a hall sensor. When the can lid is closed with the can body, the first detector 320 (hall sensor) detects the object 310 (magnet), and its switch is closed. When the can lid is opened, the first detector 320 (hall sensor) does not detect the object 310 (magnet), and the switch is turned off.
Of course, other forms of the first detector and the matched detected piece can be adopted to detect the opening and closing state of the tank cover of the liquid nitrogen tank. Alternatively, the open/close state of the lid of the liquid nitrogen tank may be detected in an appropriate manner without using a detector that is not matched with the object to be detected. The present application is not limited in this regard.
In one embodiment, the detection assembly 300 includes a second detector 330 and a third detector 340. The second detector 330 is used to detect whether the moving member 100 is locked, and the third detecting device 340 is used to detect whether the moving member 100 is unlocked.

The second detector 330 is used to detect whether the moving component 100 is located at the second position, so as to detect whether the moving component 100 is locked. The third detector 310 is used to detect whether the moving component 100 is at the third position, so as to detect whether the moving component 100 completes unlocking.
In the embodiment, the detection of the locking state of the moving component 100 is accurately and effectively realized by detecting the moving position of the moving component 100.
Of course, in other embodiments, the locked state of the moving component 100 may be detected in other manners. Nor is the application limited thereto.
As an example, the second detector 330 and/or the third detector 340 may be a micro switch.
