Description

负压消臭窄隙风帘口便口结构 技术领域
本发明涉及便器构件，特别涉及便器的负压消臭装置构件。
 背景技术
中国专利，专利号：ZL00113262.8，公开日：2001年10月10日，公开内容包括一项涉及便器负压消臭的技术方案，该技术方案业已阐述清楚的发明构思是，便器的负压装置由固定风道、活动风道、抽排风装置组成，中空结构的罩板兼有活动风道功能，由它实现便槽与固定风道，包括抽排风装置的联系，属于保障便器负压消臭功能的关键性部件。
但依据该技术方案完成的多台次应用实例，实际表现出的负压消臭效果欠理想，其不足具体表现在：一、负压空间范围小，仅仅局限于罩板排便口以下的便槽内部空间，排便口以上空间负压效果很难体现，这意味取蹲姿排便时，由于肛门到排便口有一距离，针对排便自脱离肛门到进入排便口间所产生臭气缺乏抑制能力；二、即使在排便口，自排便口各处实际的负压效果也明显不均匀，排便口两远端负压效果趋近零，总体抑臭效果欠理想。
虽然这些不足可以通过加大抽排风功率获得解决，但通过单纯加大抽排风功率实现负压保障，导致能源浪费，运行成本增加和有可能导致排便者排便时感觉不适。
本发明人通过深入分析研究，总结出背景技术方案的不足主要成因在于，风道前端的进风口结构形式，设置位置以及风道结构形式设置欠佳。具体表现在，
进风口结构形式与设置位置：进风口设于罩板内底板，取为矩形开口，在数量上取为与导风口设置数量相同，对称布置于排便口的两侧，位于排便口单侧的进风口设孔总长显著小于排便口长度，且设孔宽度较宽，孔的矩形开口最外沿距相对应的排便口下缘有较大距离，未与排便口实施贴近；
风道结构形式：进风口与设于罩板内底板的导风口间相通的风道通道结构为单一腔室结构；
受进风口形状与位置约束以及风道的单一腔室结构决定，从排便口进入的气流流量小，流速慢和流动范围小，距离进风口较远和较偏处的负压和距离进风口较近和位置较正处的负压差距明显，覆盖排便口的风帘难以形成，排便口上方的负压消臭效果不明显，以及排便口各处负压效果欠均匀，导致总体抑臭效果欠理想。
便器的负压主动消臭技术，是一项具有显著实用价值的技术方案。
在保持低的抽排风功率前提下，如何获得具有显著负压消臭效果的便器，针对背景技术方案的不足，本发明人在前述背景技术基础上作出新的技术发明方案改进，发明了新的有效应对技术措施，经最新验证样机证明，已经理想和成功地解决了上述背景技术的不足。
背景技术中的罩板主体结构由面板，内底板，口围三者组成，“口围”的概念虽然在背景技术说明书中未见提及，但它是罩板结构中不可或缺的重要功能构件，在背景技术说明书P13. “图1 一种实施例为具有刮片除便，微液冲洗，负压排臭，尿粪分排和底入式单活门与防泻便回流强制送便的一种坐式便器结构原理图”，中已经作出事实性表达。
为后述的对本技术发明方案的表述准确和理解方便起见，在本发明中保留“进风口”称谓，将背景技术中所称 “罩板”，在本发明中改称为“盖体”；将在背景技术中所称“罩板”的内底板上实质开设的与导风口相通和未予显示和未予命名的开口，在本发明中将其称为“出风口”；将所称“活动风道”改称为“内置风道”，将所称“面板”，“底板”，包括“口围”在本发明中改称为“盖体面板”，“盖体内底板”，“排便口口围”。
技术问题
仅通过单纯对盖体的进风口形状、位置和内置风道实施结构改进，使背景技术中的盖体无论作为背景技术中的可装拆的活动风道的独立结构体，或作为新的改进的不再具有活动特征，与便器的便体结合成一体的结构体，都能实现在低的抽排风功率前提下，排便口上方自排便人肛门至排便口距离范围内有明显负压形成，和使沿排便口长度方向同一直线上的负压值接近相等，为便器获得理想负压消臭效果提供关键支持。
 技术解决方案
负压消臭窄隙风帘口便口结构，包括盖体面板，盖体内底板，排便口口围，其特征在于：进风口取为盖体内底板所设开口与排便口口围垂直立面内表面间所形成的窄隙，内置风道间还设置有气流导引结构件。
本发明的技术特征还在于：所述气流导引结构件，取为自排便口口围垂直立面内表面始，面向出风口侧延伸一距离，和平行于盖体面板内表面，与盖体内底板内表面间有距离构成窄隙的薄板结构的气流导引板。
或者，所述气流导引结构件，还包括取为竖置于盖体面板内表面与盖体内底板内表面间薄板结构的隔片，设置一片以上，将盖体面板内表面与盖体内底板内表面由进风口到出风口间形成的内置风道分割成两条或两条以上的内置导流风道。
 有益效果
针对进风口实施的上述改进措施和针对内置风道实施的上述改进措施，在原抽排风功率不变前提下，可促使经过排便口口围的气流获得更高速度，和改善距离出风口较远和较偏处的排便口口围的气流流动效果，进风口或者说排便口口围各处的流入空气流量或流速趋近一致，排便口包括排便口近体上方获得接近均匀的风帘，空气的流动范围能够扩展至排便口上方，支持便器获得理想负压消臭效果。
