When the wine jar 300 leaks, the second float 141 drives the second free end of the second elastic component 1421 to move, the buoyancy force applied to the second float 141 is reduced as the liquid level moves downwards, the second float 141 moves the supporting plate 1423 under the action of the gravity of the second float 141, so that the supporting plate 1423 is twisted by a certain angle, the inertia measurement component 1422 is further deflected by a corresponding angle, and when the moving angle of the second free end exceeds a preset alarm threshold value, the inertia measurement component 1422 generates and outputs the trigger signal, and the alarm module 204 alarms.

In an embodiment, the host 200 further includes a storage battery 203 for supplying power to at least one of the main control module 201, the alarm module 204, and the triggering device 100.

It can be understood that the storage battery 203 is electrically connected to at least one of the main control module 201, the alarm module 204, the wireless transmission module 202 and the triggering device to supply power. On the basis of the above example, when the triggering device is an ultrasonic detection assembly, an optical detection assembly or the triggering device outputs a triggering signal by using an inertial measurement assembly, the storage battery 203 may supply power to the triggering device; when the trigger device outputs the trigger signal by adopting the trigger switch, the power supply for the trigger device is not needed.

Further, the host 200 includes a housing, and the storage battery 203 may be packaged in the housing of the host 200, so as to avoid the situation of inconvenient power supply.

In order to achieve the above object, the utility model also provides a liquid level detection system, including wine jar 300, gateway, high in the clouds database, terminal 205 and as above the wine jar liquid level detection device that the example is shown, wine jar 300 with wine jar liquid level detection device all has a plurality ofly, and is a plurality of wine jar liquid level detection device sets up in a plurality of one to one wine jar 300, and via wireless transfer module 202 inserts the gateway, the gateway with terminal 205 respectively with high in the clouds database communication connection.

In order to realize radio communication to the wine jar of depositing of a plurality of wine jars of real-time detection and liquid level variable volume, when reaching preset alarm threshold value, the wine jar liquid level detection device of each wine jar corresponds the warning and reminds, effectively solves to detect inconveniently and can not in time discover the problem that the wine jar was revealed.

The specific implementation examples of the wine jar liquid level detection device are as described above, and are not described herein.

The above is only the optional embodiment of the present invention, and not therefore the limit of the patent scope of the present invention, all of which are in the concept of the present invention, the equivalent structure transformation of the content of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
