Description
Technical Field
[0001] This utility model relates to the field of spiral window opener technology, and in particular to an electronically limited spiral window opener. Background Technology
[0002] With the continuous improvement of building intelligence and automation, window openers are being used more and more widely in modern buildings.
[0003] Traditional window openers have several shortcomings: Firstly, in terms of transmission, some use chain or belt drives, which are prone to problems such as chain loosening and belt slippage during long-term use, leading to uneven opening and closing of doors and windows, affecting the user experience, and incurring high maintenance costs. Secondly, in terms of limit control, most use mechanical limit structures, such as limit blocks, which have low limiting accuracy, making it difficult to precisely control the opening angle of doors and windows. Furthermore, mechanical limit components are prone to wear after frequent use, leading to limit failure and posing safety hazards. In addition, traditional window openers have relatively simple control methods and lack intelligent adjustment functions, failing to meet users' needs for precise control and personalized use of doors and windows. Therefore, we propose an electronic limit spiral window opener. Utility Model Content
