Abstract: An electronic device includes a waterproof case, including a closed space, and a flow guide assembly, an electronic module and a cover, provided in the closed space. The cover includes a cover top plate and a cover side plate which, together with a case bottom plate and a case side plate, form an accommodation space for accommodating the flow guide assembly and the electronic module. Further, the cover includes a first vent hole and a second vent hole. The flow guide assembly is configured to guide air, entering the accommodation space from the first vent hole, to flow through the electronic module and to be discharged from the second vent hole. The flow guide assembly is further configured to guide air, entering the cavity from the first vent hole, to flow through the electronic module and to be discharged from the second vent hole.

Abstract: This application discloses a data processing apparatus. In an embodiment, the apparatus includes a box that accommodates a data processing module and a moving component disposed on the box, and the moving component includes a rolling member. In an embodiment, the box is used for accommodating the data processing module used for performing data processing, and the moving component is disposed on the box. By rolling of the rolling member in the moving component, the data processing apparatus may be moved. When data processing services need to be executed in different scenarios, the data processing apparatus can be moved to different scenarios by using the rolling member, which is very convenient.
