Description

Bladeless fan storage box

Technical Field

The invention relates to the technical field of bladeless fan storage, in particular to a bladeless fan storage box.

Background

The bladeless fan is a common household appliance in life, and generally comprises a base and a nozzle, wherein the nozzle is fixedly connected with a connecting structure which is detachably connected with the base, the nozzle is generally annular, and a motor and an impeller are arranged in the base; in the actual use process, the motor drives the impeller to generate air flow, and the air flow is output through the nozzle, so that the requirement of blowing and cooling of a user is met.

In the process of transporting the bladeless fan out of a factory, the base and the nozzle are usually connected, and then the whole bladeless fan is placed into a storage box for transportation; however, the nozzle is generally made of plastic, the total weight is relatively light, and the motor, the impeller and other parts are arranged in the base part, so that the total weight of the base is several times of that of the nozzle; and in the transportation process of the bladeless fan, especially when the base is arranged on the upper side and the nozzle is arranged on the lower side, when the storage box is impacted by external force, the nozzle can shake at a certain angle relative to the base, so that the connecting structure between the base and the nozzle is easy to damage due to stress.

Therefore, how to prevent the connection structure between the base and the nozzle from being damaged due to external impact in the process of transporting the bladeless fan is a problem which needs to be solved urgently at present.
