AI Technical Summary

Technical Problem

The check valves of existing toy blowpipes are prone to failure due to water vapor condensation, and the blowpipes tend to roll, causing inconvenience and hygiene problems.

Method used

A check valve structure is installed inside the blowpipe, and a sealing gasket and valve core assembly are used. The valve core is designed with a concave-convex air guide groove structure. Combined with the convex arc surface design of the anti-roll connecting pipe, it prevents water vapor vacuum adsorption and restricts the rolling of the blowpipe.

Benefits of technology

It improves the long-term stability and airflow smoothness of the check valve, extends its service life, and prevents contamination caused by the rolling of the blowpipe.

Abstract

本实用新型公开了一种防止止逆失效的玩具吹管，涉及玩具技术领域，包括吹管本体，所述吹管本体的下端上固定安装有防滚连接管，防滚连接管的下端固定安装有排气管，本实用新型，在管体内部设置止逆结构，该止逆结构配备有密封垫片，且密封垫片与阀芯组件相互接触，同时，在阀芯上精心设计了若干凹凸导气槽结构，这种设计的作用在于，通过凹凸导气槽结构减小密封垫片与阀芯之间的贴合面积，从而防止水汽在两者之间形成真空吸附现象，进而提升止逆阀在长期使用过程中的稳定性，又能保障气流的顺畅流通，并且还能有效的延长吹管使用寿命，提高产品稳定性，同时防滚结构简单易成型，在管体放置时，能有效的避免掉落造成对管体的污染。
