Abstract

一种试剂盒用喷嘴，其包括环环形套管(1)、设置在环形套管(1)一端的端板(2)、设置在端板(2)中心的喷嘴管(3)以及设置在喷嘴管(3)端部的锥形喷口(4)，端板(2)上还设置有环绕在喷嘴管(3)外周的环形档边(5)，喷嘴管(3)与锥形喷口(4)内设置有与环形套管(1)内部连通的液体通道(6)，喷嘴管(3)与环形档边(5)之间围合形成环形沟槽(7)。这种试剂盒用喷嘴的锥形喷口可避免液体挂滴，环形挡边和沟槽可防止细长喷嘴管被外力损坏。

Description

一种试剂盒用喷嘴 技术领域
本发明涉及一种试剂盒用喷嘴。
 背景技术
试剂盒是实验室常见的实验用品，用于反应试剂的保存。对于液体试剂而言，试剂盒设置有出液口将其从试剂盒内的储液槽中放出。试剂盒的出液口通常连通一个管状结构并设置喷嘴以便控制出液，喷嘴应当保证使用时正常出液，同时还要利于封堵并足够坚固，防止试剂盒在运输中被损坏而造成其内部的反应试剂泄漏。
 技术问题
本发明的目的是提供一种结构简单、可避免液体挂滴且不易损坏的试剂盒用喷嘴。
 技术解决方案
本发明采用如下技术方案：
一种试剂盒用喷嘴，其包括环形套管、设置在环形套管一端的端板、设置在端板中心的喷嘴管以及设置在喷嘴管端部的锥形喷口，所述端板上还设置有环绕在喷嘴管外周的环形档边，所述喷嘴管与锥形喷口内设置有与环形套管内部连通的液体通道，所述喷嘴管与环形档边之间围合形成环形沟槽。
其中，所述环形套管的内设置有环形卡扣槽。
其中，所述环形套管的开口端设置有锥形导向面。
其中，所述喷嘴管为锥台形或圆柱形。
 有益效果
本发明的有益效果在于：本发明的锥形喷口处为锥面设计，防止液体挂滴。喷嘴管外侧有环形档边和环形沟槽，防止细长喷嘴管被外力破坏，沟槽还可以在安装密封盖时，卡住密封盖，使密封盖不易脱落。本发明安装方便，喷液效果好。
 附图说明
图1为本发明的结构示意图。
图2为本发明的剖面结构示意图。
 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整的描述。
如图1和图2所示，一种试剂盒用喷嘴，其包括环形套管1、设置在环形套管1一端的端板2、设置在端板2中心的喷嘴管3以及设置在喷嘴管3端部的锥形喷口4，所述端板2上还设置有环绕在喷嘴管3外周的环形档边5，所述喷嘴管3与锥形喷口4内设置有与环形套管1内部连通的液体通道6，所述喷嘴管3与环形档边5之间围合形成环形沟槽7。
喷嘴的锥形喷口处为锥面设计，防止液体挂滴。所述喷嘴管3为锥台形或圆柱形，喷嘴管外侧有环形档边和环形沟槽，防止细长喷嘴管被外力破坏，沟槽还可以在安装密封盖时，卡住密封盖，使密封盖不易脱落。
所述环形套管1的内设置有环形卡扣槽8。喷嘴与试剂盒喷管安装处的卡扣相配合，喷管插入环形套管内，安装方便直接，不易脱落。液体试剂经试剂盒的出液口和喷管后，由喷嘴内的液体通道喷出。
所述环形套管1的开口端设置有锥形导向面9。锥形导向面利于与试剂盒的喷管的相适配，利于插装。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
