Description

滤芯及过滤水壶 技术领域
本申请涉及水处理领域，尤其涉及一种用来净化自来水的滤芯及过滤水壶。
背景技术
自来水净化是直接过滤家庭日常使用的自来水，使其完全达到厨房做饭及饮用的标准。这样的净化设备有很多种，例如净水器、过滤水壶。在自来水净化的过程中，人们会根据不同的饮水要求来选择功能不同滤芯，例如授权公告号为CN201350371Y的实用新型专利公开了一种便于更换的大容量过滤水壶滤芯，滤芯需要有较大的容量才能保证较好的过滤效果，导致滤芯的体积偏大；授权公告号为CN201756480U的实用新型专利公开了一种分离式直饮滤芯，为了灵活的实现多种过滤功能，将滤芯分体设置，也导致滤芯的体积偏大，对净水器或者过滤水壶的造型设计带来瓶颈问题。
发明内容
鉴于目前滤芯存在的上述不足，本申请提供一种滤芯，能够在保证好的过滤效果的同时减小滤芯的体积。
为达到上述目的，本申请的实施例采用如下技术方案：
滤芯，所述滤芯包括壳体和设置在壳体内部的滤料，所述壳体上设有进水口和出水口，所述滤芯内部还设有至少一块隔板，所述隔板使所述进水口和所述出水口之间的水流通道的长度大于所述进水口和所述出水口之间的直线距离。
通过设置隔板，增加了水流通道的长度，以及水和滤料的接触时间，提高了滤料滤水的效率，在同样的过滤效果下，可以使用更少的滤料，进而可以使滤芯的体积减小。此外，通过隔板将壳体内部分成多个容置空间，通过设置滤网等隔离装置，还可以在不同的容置空间中装填不同的滤料，实现多种过滤功能。
优选的，所述隔板使进水口和出水口之间的水流通道包括弯曲形状。弯曲的形状可以更好的延长水流通道的长度，且能使水在滤料中的流动更加顺畅。
优选的，所述弯曲形状为U形或者波形。所述波形是指至少有一个波峰和至少一个波谷，且波峰和波谷平滑过渡的形状，例如，S形、W形、或者U形、S形和W形进行任意组合的形状。将弯曲形状设置为U形或者波形等规则形状，可以更加方便的定量计算滤芯的过滤效果，使滤芯过滤效果更加精准，更好控制，滤芯的设计能更好的满足国家的相关标准。
优选的，所述波形上设有至少一个排气阀，排气阀可以排除水中的空气，有效的减小水流在水流通道中流动的气阻，加快水流在滤芯内的流速，使滤芯过滤时间更短；更优选的，所述排气阀设置在波峰位置处，可以更好的排除空气，更加有效的减少气阻。
优选的，所述隔板在壳体内竖向设置或者横向设置。所述竖向设置是指隔板设置在壳体的上表面或/和下表面上，隔板可以垂直于壳体的上表面或者下表面，也可以与壳体的上表面或者下表面保持一定的角度；所述横向设置是指隔板设置在壳体的侧壁上，可以垂直与壳体的侧壁设置，也可以与壳体保持一定的角度。通过将隔板横向设置或者竖向设置，使水流通道竖向延伸或者横向延伸，能提高滤料过滤水的效率。当所述隔板竖向设置时，设置在下表面的隔板还能使壳体具有一定的蓄水的效果，使滤料保持湿润的状态，即使在一段时间不使用，也能保持活化状态。此外，当所述隔板横向设置时，若隔板倾斜设置且隔板的渗水口高于隔板与侧壁的连接处，则隔板也具有一定的蓄水效果。当然，在必要的情况下，也可以在同一滤芯内同时设置横向隔板和竖向隔板，满足特殊形状的水流通道的设计要求。
优选的，所述隔板竖向设置时,所述出水口低于进水口设置或者与进水口等高设置，所述出水口与进水口之间高度差D的取值范围是0≤D≤H，其中H是壳体的高度。更优选的，所述出水口与进水口之间的高度差D的取值范围是0≤D≤0.5H。当所述出水口和进水口之间的高度差为0时，出水管与进水口等高，壳体的蓄水空间达到最大，蓄水效果更好。所述出水口和进水口之间的高度差为H时，出水口设置在壳体的底部，可以加快水的流速，使过滤时间更短。当出水口与进水口之间的高度差D的取值范围是0≤D≤0.5H时，可以保证较好的蓄水效果。
优选的，所述隔板横向设置时，所述隔板的渗水口处设有竖向的 凸沿，所述凸沿与所述隔板形成蓄水结构。可以使隔板具备蓄水功能，适用于需要保湿的滤料。
优选的，所述隔板与壳体的夹角a的范围是0<a≤90度。隔板与壳体保持一定的夹角，是隔板是设置形式可以多样化，可以满足不同性能的滤料和不同形状的水流通道的要求，延长水流通道或者达到其他的效果。例如，可以将隔板倾斜设置成喇叭状，是进水口最大等等。
优选的，所述隔板与壳体的夹角a的范围是45度≤a≤90度。可以使水流通道更长。
优选的，所述隔板设有向滤料延伸的自由端，所述自由端和壳体形成渗水通道。所述隔板与壳体连接处使水流无法通过，向滤料延伸的自由端与壳体之间的距离形成渗水通道，通过设置一块隔板，或者在相对的两个面上交替设置隔板，即可使水流形成弯曲的形状，例如，U形、S形、W形、或者U形、S形和W形进行任意组合的形状。
优选的，所述隔板与壳体连接且所述隔板上设有渗水口。所述隔板的边缘与壳体连接，阻止水流通过，设置在壳体上的渗水口形成水流的通道，渗水口的位置可以根据水流通道的形状进行设计，使水流通道呈现出曲线形状。
优选的，所述隔板设置为闭合形状或者平板状；更优选的，所述闭合形状为圆环状，椭圆环状、多边形闭合形状或者不规则的闭合形状中的一种，隔板的具体形状可以根据水流通道的弯曲形状以及进水口和出水口的位置进行选择，例如，进水口和出水口分别设置在滤芯的中心和边缘，水流通道呈U形，可以选择闭合形状的隔板；进水口和出水口设置在滤芯相对的侧壁上，水流通道呈W形，可以选择平板状的隔板。
本申请进一步的目地在于提供一种过滤水壶，所述过滤水壶包括如上所述的滤芯。所述过滤水壶一般包括过滤前的储水部分和过滤后的储水部分，所述滤芯设置在过滤前的储水部分和过滤后的储水部分连接处。
本申请实施的优点：本申请提供了一种滤芯，所述滤芯包括壳体和设置在壳体内部的滤料，所述壳体上设有进水口和出水口，所述滤芯内部还设有至少一块隔板，所述隔板使所述进水口和所述出水口之间的水流通道的长度大于所述进水口和所述出水口之间的直线距离， 通过上述技术方案，能够在保证好的过滤效果的同时减小滤芯的体积，进而使过滤水壶和净水器的造型设计不受滤芯体积过大的限制，此外，通过控制出水口与进水口之间的高度差，可以使滤芯具有蓄水功能，在长时间不使用滤芯时，仍使滤芯内的滤料具有较好的活性，本申请还提供了一种使用了上述滤芯的过滤水壶。
