As shown in fig. 1 to 3, an electromagnetic door opener for a storage cabinet according to an embodiment of the present invention includes: a shell 1, a coil 2 and a metal core 3.
The shell 1 is provided with an installation cavity, the coil 2 is arranged in the installation cavity, the coil 2 is sleeved on the outer side of the metal inner core 3, and the section of the metal inner core 3 in the direction perpendicular to the length direction of the metal inner core is a first elliptical section. The metal inner core 3 is used for providing driving force for opening a door body of the storage cabinet.
The metal inner core 3 is suitable for generating linear motion under the condition that the coil 2 is electrified, so that the door body of the storage cabinet is switched into an opening state.
According to the electromagnetic door opening device of the storage cabinet, the metal inner core 3 is designed into the inner core with the oval section, and compared with the circular metal inner core 3 with the same section area in the related technology, on one hand, the same pushing force can be generated, so that the normal opening of a door body is ensured; on the other hand, the height of the metal inner core 3 is smaller, the overall thickness of the electromagnetic door opener can be reduced, the universality of the electromagnetic door opener is improved, and the electromagnetic door opener can be suitable for storage cabinets of different types.
According to the embodiment of the utility model, when a user needs to switch the door body to the opening state, the coil 2 is connected with a power supply, the coil 2 generates a strong magnetic field after being powered on, and the metal inner core 3 inside the coil 2 moves towards the direction close to the door body under the action of the magnetic field, so that the door body is driven to be switched to the opening state.
In one embodiment of the present invention, if the length direction of the metal core 3 is oriented in the front-rear direction, any cross section of the metal core 3 perpendicular to the front-rear direction is an elliptical cross section, and further, the dimension of any first elliptical cross section is the same, that is, the metal core 3 is an elliptical columnar core. Therefore, the uniformity of stress of the metal inner core 3 in a magnetic field can be ensured, and the stable motion of the metal inner core 3 is ensured.
According to the embodiment of the present invention, the metal core 3 may be, but not limited to, an iron core, and the metal core 3 may also be a metal core made of other materials, and the present invention is not particularly limited herein as long as the metal core 3 can perform linear motion after the coil 2 is powered on.

In an embodiment of the present invention, if the length direction of the coil 2 is oriented in the front-rear direction, any cross section of the coil 2 perpendicular to the front-rear direction is an elliptical cross section, and further, the dimension of any second elliptical cross section is the same, that is, the coil 2 is an elliptical columnar coil 2.
