At this time, impurities in the raw water will be trapped in the raw water channel 310 of the filter material 30.
  • the air bag 40 in the container 10 will be compressed under the action of water pressure, which can effectively eliminate the water hammer impact on the filter water purifier;
  • the purified water filtered in the container 10 is used to reversely flush the filter material 30, so that the impurities and sewage intercepted by the filter material 30 are flushed into the raw water channel 310 and discharged through the sewage channel 124.
  • the raw water channel 310 is connected to the second communication port 202, and the first communication port 201 is connected to the sewage channel 124.
  • the sewage channel 124 is equivalent to a pressure relief port.
  • the air bag 40 will lose pressure and expand, and the purified water in the container 10, which is equal to the expanded volume of the air bag 40, will be squeezed back to the raw water channel 310 of the filter material 30, and the impurities and sewage intercepted in the raw water channel 310 will be flushed down and discharged out of the container 10 through the sewage channel 124.
  • the volume of the raw water channel 310 of the filter material 30 is about 1/15 of the overall volume of the filter material 30.
  • the water capacity of the raw water channel 310 is about 150 ml, which is relatively small and close to the contracted volume of the air bag 40. Therefore, the pressure generated by the decompression expansion of the air bag 40 can just be used to discharge the impurities and sewage in the raw water channel 310.
  • the external connecting water pipe and the main bottle 110 themselves will also expand and contract under the action of water pressure. Therefore, the volume deformation of the air bag 40, the water pipe and the main bottle 110 after decompression is generally greater than the volume of the raw water channel 310 of the filter material 30. In this way, impurities and sewage can be discharged without wasting too much flushing water.
  • Backwashing is the process of water flowing in the opposite direction from the outer surface of the filter material 30 to the inner hole of the filter material 30.
  • the outer surface area of the filter material 30 is usually more than 15 times the inner surface area of the inner hole.
  • the flow rate of water per unit area on the inner surface of the filter material 30 is 15 times that on its outer surface. Therefore, the flushing effect of flushing from the outside of the filter material 30 to the inside is much better than flushing from the inside to the outside.
  • the flushing effect depends on the instantaneous pressure difference generated on the surface of the filter material 30.
  • the impurities adhered to the filter material 30 will be instantly washed away, and then these impurities will be discharged from the sewage channel 124.
  • the impurities can be discharged cleanly with an amount of water equal to that of the raw water channel 310. There is no need to consume a large amount of water for flushing, and the flushing effect is better. After the flushing is completed, the valve body 20 can be rotated to return to the initial filtering state.
  • the filter material 30 can be backwashed with filtered clean water, thereby avoiding secondary contamination of the filter material 30 and making it healthier to use.
  • the filtering structure of the water purifier from the inside to the outside can achieve very high precision without affecting the water pressure. Since the filtering area of the outer layer of the filter material 30 is 15 times that of the inner layer, the resistance is lower, and the filtering precision of the filter material 30 can be gradually improved from the inside to the outside. Even the outer layer of the filter material 30 is 15 times that of the inner layer without increasing the resistance of the filter material 30.
  • the conventional filter has a filtering structure from the outside to the inside, and the inner surface of the filter material 30 is 1/15 of the outer surface. It is impossible to improve the filtering precision without increasing the resistance.
  • the filter's inside-out filtering structure combined with the transparent bottle container 10, makes it easy to observe the usage status of the filter material 30. If the interception capacity of the filter material 30 is saturated, the outermost layer of the filter material 30 will change color, indicating that the entire filter material 30 has been penetrated by pollutants and needs to be replaced.
  • the conventional filter has an outside-in filtering structure, in which water flows through the filter material 30 from the outside to the inside, and the outer layer of the filter material 30 changes color easily. However, whether it should be replaced depends on the status of the inner layer of the filter material 30.

为了使本领域技术人员更好地理解本申请的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请一并参阅图1至图6，本实施例提供一种新型反冲洗过滤净水器，包括容器10、滤材30以及阀体20，容器10包括主体瓶110和主体盖120，主体盖120具有进水通道121、出水通道122和排污通道124，出水通道122与主体瓶110的内腔连通；滤材30沿竖向设置于容器10内，且滤材30设置有原水通道310；阀体20可转动地设置于主体盖120上，阀体20的外部开设有第一连通口201和第二连通口202，第一连通口201与第二连通口202经由阀体20的内部水腔相连通设置；其中，阀体20具有过滤状态和反冲洗状态，当阀体20转至过滤状态时，进水通道121与第一连通口201连通，第二连通口202与原水通道310连通，当阀体20转至反冲洗状态时，原水通道310与第二连通口202连通，第一连通口201与排污通道124连通。
可以看出，本实施例的反冲洗过滤净水器，当阀体20转至过滤状态时，进水通道121与第一连通口201连通，第二连通口202与原水通道310连通，以使从进水通道121流入的原水经由第一连通口201和第二连通口202而流入到滤材30的原水通道310内，以通过滤材30由内向外过滤之后流入到容器10内并通过出水通道122流出，从而供人们生活使用，当阀体20转至反冲洗状态时，原水通道310与第二连通口202连通，第一连通口201与排污通道124连通，以使容器10内过滤后的净水反向冲洗滤材30，从而实现滤材30过滤所拦截下来的杂质和污水被冲入到原水通道310中并经由排污通道124排出，如此，使用过滤后的净水而不是未处理的原水反向冲刷滤材30，避免了滤材30被二次污染，滤材30采用由内侧向外侧过滤的方式，与常规过滤器的过滤结构原理恰恰相反，反冲洗时，容器10内过滤后的净水会反向冲刷滤材30并流入到原水通道310内，由于原水通道310内侧滤材30表面积较小，在同样的冲洗流量下，单位面积的冲洗流速较快，从而有效提升了冲洗效果，整个滤材30从外到内都会被冲洗，且能将大部分的杂质和污水冲刷在原水通道310内并通过排污通道124可以排出，以恢复滤材30的过滤性能，提高滤材30的使用寿命，结构简单、成本低，故障率低、便于维护、易于生产，实用性较好。
在本实施例中，滤材30为卷筒状结构，可采用pp棉滤筒，pp棉滤筒是由无毒无味的聚丙烯(PP)为原料，经过加热熔融、喷丝、牵引、接受成形而制成的卷筒状滤材30，pp棉滤筒具有孔径均匀，外疏内密的深层过滤结构，并具有过滤效率高，耐酸碱的优良特性，且在滤材30的中心位置沿竖向延伸形成原水通道310，原水通道310的顶部呈第一开口321设置，第二连通口202设置于阀体20的底部，第二连通口202通过第一开口321与原水通道310连通。
具体而言，主体盖120设置有柱状的容置腔125，阀体20可转动地安装在容置腔125内，进水通道121和排污通道124分别与容置腔125的侧壁贯通设置，第一连通口201设置于阀体20的外周表面，以通过转动阀体20从而使第一连通口201与进水通道121或排污通道124连通，其中，当阀体20转至过滤状态时第一连通口201与进水通道121连通，当阀体20转至反冲洗状态时第一连通口201与排污通道124连通，阀体20可采用电机自动操控的方式或手动旋转操控的方式。
进一步地，容置腔125的底部呈第二开口126设置，第二开口126与第一开口321相连通设置，以使第二连通口202经由第一开口321和第二开口126并与原水通道310相连通，其中，滤材30的顶部盖合有上盖体320，上盖体320的中部往上突出延伸以形成第一开口321，以通过第一开口321插设于第二开口126中从而实现第二连通口202原水通道310相连通，且第一开口321与第二开口126之间设置有软胶圈以起到密封的效果。
在本实施例中，阀体20包括阀芯和操控手柄220，阀芯可转动地安装在容置腔125内，阀芯的顶部设置有连接杆210，连接杆210穿过容置腔125的顶壁并与操控手柄220连接，其中，阀芯为柱状结构，以通过用手扳动操控手柄220即可使阀芯旋转从而切换阀体20于过滤状态和反冲洗状态之间，结构简单，操作过程简便。
具体而言，进水通道121的中轴线沿水平方向延伸设置，排污通道124的中轴线沿水平方向延伸设置，且排污通道124的中轴线与进水通道121的中轴线相垂直设置，如此，通过顺时针或逆时针旋转阀体20至90度，即可实现切换阀体20于过滤状态和反冲洗状态之间。
进一步地，排污通道124的数量为两个，两个排污通道124呈相对设置，第一连通口201的数量为两个，两个第一连通口201呈相对设置，当阀体20转至反冲洗状态时，两个第一连通口201与两个排污通道124一一对应地相连通设置，进水通道121被阀体20的外壁遮挡封堵住，当阀体20转至过滤状态时，其中一个第一连通口201与进水通道121相连通，另一个第一连通口201被遮挡封堵住，排污通道124被阀体20的外壁遮挡封堵住，如此，通过设置两个相对的排污通道124，使得操控手柄220无论是逆时针还是顺时针旋转90度都能够使得阀体20切换至反冲洗状态，以防止该容器10安装在室内空间狭窄的区域内而导致操控手柄220在手动旋转时受限，适用性较好，便于安装，从而提升产品的实用性和便利性。
在本实施例中，该反冲洗过滤净水器还包括空气囊40，空气囊40放置于容器10内，空气囊40包括具有密闭空间的薄膜囊体410，密闭空间内充入有气体，薄膜囊体410可采用PE材质制作而成，以使空气囊40在水压作用下被压缩从而消除净水器所受到的水锤冲击，并在阀体20转至反冲洗状态时，以通过空气囊40失压膨胀而使得容器10内过滤后的净水反向冲洗滤材30，从而实现滤材30过滤所拦截下来的杂质和污水被冲入到原水通道310中并经由排污通道124排出。
具体而言，滤材30的底部与主体瓶110的底壁之间设置有安装柱111，空气囊40为环状结构，以在空气囊40的中部形成安装孔420，以使空气囊40通过安装孔420套设于安装柱111上从而进行安装，结构简单，安装方便，生产成本低，其中，安装柱111设置于主体瓶110的底壁上，滤材30的底部盖设有下盖体330，下盖体330的底部突出延伸形成有插接口331，以使滤材30通过安装柱111插设于该插接口331上从而进行安装固定，并且将空气囊40安置在滤材30的底部与主体瓶110之间的空余空间内，空间布局合理，有效提升了容器10内的空间利用率。
在其他实施例中，如图6所示，主体瓶110的内侧壁沿周向间隔设置有多个支撑筋112，滤材30的上下两端分别与主体盖120和支撑筋112相抵接，以在滤材30的下端与主体瓶110的底壁之间形成有容置空间，空气囊40放置于容置空间113内，空气囊40可采用球体状结构，如此，通过主体瓶110内侧壁的支撑筋112对滤材30进行支撑和安装，从而在滤材30的下端与主体瓶110的底壁之间形成容置空间以用于放置空气囊40，结构简单紧凑，组装方便，加工工艺难度和生产成本较低，空间布局合理，有效提升了容器10内的空间利用率。
进一步地，空气囊40的体积大致为原水通道310的容积的0.75-1.25倍，如此设置，使得空气囊40的膨胀体积与原水通道310的容积相近，以使在反冲洗状态时空气囊40失压膨胀可将与其膨胀体积等同的污水从排污通道124排出容器10外，使得空气囊40通过膨胀为滤材30进行反冲洗提供助力的效果更好，另外，可在该反冲洗过滤净水器的出水通道122侧安装外置的压力罐，在反冲洗时压力罐内部气囊会膨胀也能够为滤材30进行反冲洗提供助力，或者在该反冲洗过滤净水器的出水通道122侧采用弹性系数较小的塑料水管（如ppr水管），如此在反冲洗时水管失压收缩也能够为滤材30进行反冲洗提供助力。并将与收缩体积等同的污水从排污通道124排出容器10外。
当阀体20转至过滤状态时，未经处理的原水从进水通道121经由阀体20流入到滤材30的原水通道310，通过滤材30由内向外逐层过滤后进入滤材30与主体瓶110之间的净水空间内，最终从出水通道122流出以供人们生活使用，此时原水中的杂质会被截留在滤材30原水通道310内；
在停止用水时，在水压作用下，容器10内的空气囊40会被压缩，可有效消除过滤净水器所受到的水锤冲击；
当阀体20转至反冲洗状态时，以使容器10内过滤后的净水反向冲洗滤材30，从而实现滤材30过滤所拦截下来的杂质和污水被冲入到原水通道310中并经由排污通道124排出，此时原水通道310与第二连通口202连通，第一连通口201与排污通道124连通，排污通道124口相当于就是泄压口，空气囊40会失压膨胀，将容器10内与空气囊40膨胀体积相等的净水反向挤向滤材30的原水通道310，并将原水通道310内拦截下来的杂质和污水冲刷下来并从排污通道124排出容器10外；
其中，滤材30原水通道310体积约为滤材30整体体积的1/15，原水通道310的容水量约为150ml，体积较小，与空气囊40的收缩体积相近，所以利用空气囊40失压膨胀产生的压力刚好可以将原水通道310内的杂质和污水排出干净，除了利用空气囊40，外部连接水管和主体瓶110本身在水压作用也会膨胀收缩，所以空气囊40外加水管和主体瓶110在失压后产生的体积形变一般要大于滤材30原水通道310的体积，这样既能将杂质和污水排除干净，又不会过多浪费冲洗用水。
反冲洗是水通过滤材30外表面向滤材30内孔反向流动，滤材30的外表面积通常是内孔内表面积的15倍以上，同样的冲洗水量，水在滤材30内表面单位面积的流速是在其外表面上的15倍，所以从滤材30外向内冲洗的冲洗效果要远好过从内向外冲洗，冲洗效果取决于在滤材30表面产生的瞬时压差，当滤材30从过滤状态切换到反冲洗状态时，过滤净水器内部与排污通道124间会形成压差，滤材30切换速度越快压差越大，滤材30上所粘附的杂质会被瞬间冲洗掉，然后就是这些杂质从排污通道124排出，用与原水通道310等量的水就可以将杂质排出干净，无需耗费大量的水去冲洗，而且冲洗效果较好，冲洗完成后，即可旋转阀体20再次回到初始的过滤状态。
在本实施例中，通过对阀体20的结构设计配合着空气囊40，可以实现用过滤后的净水反向冲洗滤材30，避免了滤材30被二次污染，使用更健康。
其中，该过滤净水器从内向外的过滤结构可以做到很高的精度而不影响水压，由于滤材30外层的过滤面积是内层的15倍，阻力更低，可以由内到外逐级提高滤材30的过滤精度，甚至滤材30外层是内层的15倍而不会增加滤材30的阻力，而常规的过滤器从外向内的过滤结构，滤材30内表面是外表面1/15，其无法在提高过滤精度的同时不增加阻力。
此外，过滤器从内向外的过滤结构，搭配透明瓶身的容器10，可以很方便的观察滤材30的使用状态，如果滤材30拦截能力饱和，最外层滤材30会变色，说明整个滤材30都被污染物穿透，需要进行更换，而常规的过滤器从外向内的过滤结构，水从外向内流经滤材30，滤材30外层很容易就变色了，但是否应该更换取决于滤材30内层的状态，如果滤材30内层很干净，还是可以继续使用的，但即使是透明滤瓶也无法观测到实际的状况。
从以上描述中，可以看出，本发明上述的实施例实现了如下的技术效果：
本发明的反冲洗过滤净水器，当阀体20转至过滤状态时，进水通道121与第一连通口201连通，第二连通口202与原水通道310连通，以使从进水通道121流入的原水经由第一连通口201和第二连通口202而流入到滤材30的原水通道310内，以通过滤材30由内向外过滤之后流入到容器10内并通过出水通道122流出，从而供人们生活使用，当阀体20转至反冲洗状态时，原水通道310与第二连通口202连通，第一连通口201与排污通道124连通，以使容器10内过滤后的净水反向冲洗滤材30，从而实现滤材30过滤所拦截下来的杂质和污水被冲入到原水通道310中并经由排污通道124排出，如此，使用过滤后的净水而不是未处理的原水反向冲刷滤材30，避免了滤材30被二次污染，滤材30采用由内侧向外侧过滤的方式，与常规过滤器的过滤结构原理恰恰相反，反冲洗时，容器10内过滤后的净水会反向冲刷滤材30并流入到原水通道310内，由于原水通道310内侧滤材30表面积较小，在同样的冲洗流量下，单位面积的冲洗流速较快，从而有效提升了冲洗效果，整个滤材30从外到内都会被冲洗，且能将大部分的杂质和污水冲刷在原水通道310内并通过排污通道124可以排出，以恢复滤材30的过滤性能，结构简单、成本低，故障率低、便于维护、易于生产，实用性较好。
