具体实施方式
为了使本技术领域的技术人员更好地理解本发明的技术方案，下面结合附图和最佳实施例对本发明作进一步的详细说明。
如图1-8所示，本发明包括：底座1、阀体2、热敏组件20及膜片3，
所述底座1与阀体2下端密封连接，底座1与阀体2之间围成有冷水腔 120，阀体2侧壁开有与冷水腔连通的冷水过流孔4，阀体2上端密封连接有端盖5，端盖5与阀体2之间围成有温水腔250，温水腔250内设有与阀体2同轴固接的支撑管6，阀体2上段侧壁设有温水进水孔7，阀体2中部侧壁设有温水出水孔8，阀体2内壁与支撑管之间设有连通温水进水孔7与温水出水孔8的侧通水路9；
所述热敏组件20中部与阀体2可拆卸密封连接，热敏组件20为市售产品包括温感部10及***温感部10的移动杆11，温感部10与移动杆11之间填充有感温材料，感温材料受到温度变化会膨胀或收缩，使移动杆11在温感部10内伸长或收缩，所述温感部10设于冷水腔120内，所述移动杆的自由端111与膜片支架12固接，所述膜片支架12设于温水腔250内且设于支撑管6上方，膜片支架12上可拆卸连接有扣盖13，膜片3设于膜片支架12与扣盖13之间，扣盖13与端盖5之间设有使膜片3与支撑管6上端紧密接触的复位弹簧14，如图8所示，当本实施例中的流量模块安装在恒温淋浴器上时，冷水过流孔4使冷水腔120与冷水水路18连通，恒温淋浴器内设有恒温阀芯组件17，恒温阀芯组件17的两个进口端分别与冷水水路18及热水水路19连通，热水和冷水在恒温阀芯组件17内混合呈温水，恒温阀芯组件17的出口端与本实施例中流量模块的温水进水孔7连通，如图6所示，当冷水温度过低时，温感部感应冷水温度，使移动杆11收缩，移动杆11带动膜片支架12使膜片3与支撑管6上端的间隙减小甚至完全闭合，从而减少了温水在流量模块内的瞬时流量，由于恒温阀芯组件17的作用，温水流量的降低，使进入恒温阀芯组件17内的冷水流量降低，热水与冷水混合时，热水所占比例相对提高，从而避免冷水温度过低导致温水水温降低，维持了温水温度在适当范围内，反之，如图7所示，当冷水温度过高时，温感部感应冷水温度，使移动杆11伸长，移动杆11带动膜片3之间使膜片3与支撑管6上端的间隙增大，温水既可以从侧通水路9流向温水出水孔7，还可以从膜片3与支撑管6上端之间的间隙流向温水出水孔7，增加了温水在本实施例中流量模块内的瞬时流量，由于恒温阀芯组件17的作用，温水流量的增大，使进入恒温阀芯组件17内的冷水流量增加，热水与冷水混合时，冷水所占比例相对提高，从而避免冷水温度过高导致温水水温升高，维持了温水温度在适当范围内。
优选的，所述端盖5内上端设有限位凹槽15，所述扣盖13上端设有与限位凹槽15对应的限位凸块16，当移动杆11向外运动到极限位置时，起到导向及限位的作用。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。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。
