The invention proposes an electronic mosquito catcher, which comprises a power grid part, a handle part and a first holding tank.The grip part is connected with the power grid part, and the first holding groove is arranged on the grip part. The first holding groove is selectively equipped with a first battery or a detachable battery adapter part, wherein the detachable battery adapter part is provided with a second holding groove to install a second battery.Therefore, the electronic mosquito catcher is designed to adjust the battery holding space size of the first holding tank through the detachable battery adapter, so that the electronic mosquito catcher can be used as a power supply source for batteries of different sizes and specifications, so that the user can be more elastic in use.本創作係提出一種電子捕蚊拍,係包括一電網部、一握柄部及一第一容納槽。該握柄部係與該電網部相連接;及該第一容納槽係設置於該握柄部,該第一容納槽係選擇地裝設一第一電池或一可拆式電池轉接部,其中,該可拆式電池轉接部係具有一第二容納槽,以裝設一第二電池。藉此,本創作之電子捕蚊拍係透過該可拆式電池轉接部來調整該第一容納槽的電池容置空間尺寸,使該電子捕蚊拍能夠適用不同尺寸規格的電池來作為供電來源,進而讓使用者在使用上能更具彈性。
