Description

Technical Field

[0001] This utility model relates to the field of counting equipment technology, and in particular to a fan-type counter. Background Technology

[0002] Prayer beads, also known as rosaries, are traditionally used to count the number of beads that have turned on a bracelet in one's mind. However, people often forget the number they have counted while counting, which can create a psychological burden. With the advancement of technology, electronic counters for prayer beads have emerged.

[0003] However, traditional electronic counters generally only have the function of counting, which is limited. Prayer venues are usually located in remote areas, so a compass is needed for guidance. Prayer venues are usually open spaces, so an electric fan is needed to cool them down in the hot summer. Because multiple devices (products) need to be carried, and since the prayer beads are usually carried by older teachers, they are often forgotten to bring them, which brings great inconvenience to prayer beads.

[0004] Therefore, how to provide a fan-type counter to improve the functionality of the counter has become a technical problem that urgently needs to be solved. Summary of the Invention
