Description

一种可替换清洁头的马桶刷 技术领域
本实用新型属于清洁工具技术领域，具体而言，涉及一种可替换清洁头的马桶刷。
背景技术
市场上的马桶刷清洁头和手柄基本都为整体结构，无法分离，使用时马桶擦拭头容易累积污渍、缠绕毛发不方便清洗打理，使用后插入底座或挂置于墙面，容易滋生细菌、产生异味。
针对上述情况，现有技术提出了可替换清洁头的马桶刷，虽然其可以替换清洁头，但是使用时替换过程较繁琐，替换后还需对壳体上靠近清洁头的一端进行固定装配，无法快速使用，浪费了大量时间。
实用新型内容
本实用新型的目的是针对现有技术中存在的上述问题，提出了一种更换效率高的可替换清洁头的马桶刷。
本实用新型的目的可通过下列技术方案来实现：一种可替换清洁头的马桶刷，包括呈中空的壳体和清洁头，所述的壳体内设有推杆，所述的推杆一端设有用于夹持清洁头的夹持部，另一端伸入壳体内与其轴向活动连接，所述的壳体靠近夹持部的一端设有当推杆向远离夹持部一侧运动时可使夹持部收缩的导向部，所述的壳体上设有可使推杆轴向方向锁止和解锁的锁定装置。
推杆可在壳体内轴向活动，推杆上的夹持部用于夹持清洁头，当处于解锁状态下，推杆向靠近夹持部的一侧运动时，夹持部处于非收缩状态时可更换清洁头，推杆向远离夹持部的一侧运动时可使夹持部收缩夹紧清洁头，更换效率高，当更换清洁头且被夹持部夹紧后，直接通过锁定装置使得推杆在轴向方向被锁止，更换后无需在壳体端部安装固定件对夹持头和清洁头固定，节省了大量时间，更换更加方便。
在上述的一种可替换清洁头的马桶刷中，所述的锁定装置包括设置于壳体上可解除锁止状态的按压机构、设置于壳体内设有可使推杆始终具有轴向活动趋势的弹性机构和设置于推杆上凸起的锁止部，所述的锁止部可克服弹性机构的弹力从按压机构底部滑过并顶压按压机构实现锁止。
按压机构可通过按压使其与锁止部分离进行解锁，锁止部用于顶压按压机构进行锁止，锁止状态下，弹性机构通过推杆间接给锁止部提供顶压按压机构的作用力，解锁状态下，弹性机构给推杆施加作用力后，推杆上的夹持部伸出壳体，可更换清洁头。
在上述的一种可替换清洁头的马桶刷中，所述的按压机构包括设置于壳体上与其铰接的按钮和设置于壳体与按钮之间的按压弹簧，所述的按压弹簧可使按钮始终具有顶压推杆的趋势，所述的按钮被按压后可与锁止部脱离。
由于按钮铰接在壳体上，因此按压按钮一端时，克服按压弹簧的弹力使得按钮另一端不再顶压推杆，同时也解除了锁止部与按钮相抵的锁止状态，此时，锁止部与按钮分离而无法进行限位锁止，推杆受到弹性机构的弹力作用滑向靠近夹持部的方向。
在上述的一种可替换清洁头的马桶刷中，所述的按压弹簧呈塔形。塔形的按压弹簧更适合按压机构的按钮。
在上述的一种可替换清洁头的马桶刷中，所述的锁止部上设有便于其从按钮底部滑过的第一导向斜面，所述的按钮上设有与第一导向斜面相匹配的第二导向斜面。
通过第一导向斜面和第二导向斜面的相互配合可以使得锁止部随推杆快速轴向移动至按钮下与其相抵锁止。
在上述的一种可替换清洁头的马桶刷中，所述的弹性机构包括设置于壳体内的固定件和设置于固定件与推杆之间的限位弹簧，所述的限位弹簧可使推杆上的锁止部始终具有顶压按压机构的趋势，所述的壳体内设有可防止推杆被限位弹簧弹出壳体的限位部。
通过在固定件与推杆之间设置限位弹簧来使推杆上的锁止部始终具有顶压按压机构的趋势，保证锁止效果，当处于解锁状态时，限位弹簧可通过弹性作用将推杆上的夹持部伸出壳体，便于更换清洁头。
在上述的一种可替换清洁头的马桶刷中，作为另一种方案，所述的弹性机构为设置于壳体与推杆之间的限位弹簧，所述的限位弹簧可使推杆上的锁止部始终具有顶压按压机构的趋势，所述的壳体内设有可防止推杆被限位弹簧弹出壳体的限位部。
通过直接在壳体与推杆之间设置限位弹簧，来使推杆上的锁止部始终具有顶压按压机构的趋势，保证锁止效果，当处于解锁状态时，限位弹簧可通过弹性作用将推杆上的夹持部伸出壳体，便于更换清洁头。
在上述的一种可替换清洁头的马桶刷中，所述的夹持部截面呈镊子型。截面呈镊子型的夹持部，一端容易夹紧清洁部，另一端容易被壳体压紧收缩。
在上述的一种可替换清洁头的马桶刷中，所述的夹持部具有弹性可收缩和复原。通过设置具有弹性的夹持部，可在轴向移动过程中被壳体压紧收缩或复原，对于清洁头的夹持和更换更加方便。
在上述的一种可替换清洁头的马桶刷中，所述的推杆上设有便于推动其运动的推孔，所述的壳体上设有供使用者伸入推孔的让位孔。
通过设置推孔便于使用者推动推杆进行更换清洁头或夹紧清洁头并进行锁止，通过设置让位孔供使用者伸入推孔。
与现有技术相比，本实用新型通过将一体式的滑动按钮和推杆改变为锁定装置与推杆，锁定装置可使推杆在轴向方向快速锁止或解除其锁止，推杆的轴向活动可带动夹持部快速夹紧清洁头，更换方便，效率高，且无需在壳体端部安装固定件对夹持头和清洁头固定，节省了大量时间；通过第一导向斜面和第二导向斜面的相互配合可以使得锁止部随推杆快速轴向移动至按钮下与其相抵锁止；通过在固定件与推杆之间设置限位弹簧来使推杆上的锁止部始终具有顶压按压机构的趋势，保证锁止效果，当处于解锁状态时，限位弹簧可通过弹性作用将推杆上的夹持部伸出壳体，便于更换清洁头；通过设置推孔便于使用者推动推杆进行更换清洁头或夹紧清洁头并进行锁止，通过设置让位孔供使用者伸入推孔。

通过在固定件321与推杆2之间设置限位弹簧322来使推杆2上的锁止部33始终具有顶压按压机构31的趋势，保证锁止效果，当处于解锁状态时，限位弹簧322可通过弹性作用将推杆2上的夹持部21伸出壳体1，便于更换清洁头。
通过直接在壳体1与推杆2之间设置限位弹簧322，来使推杆2上的锁止部33始终具有顶压按压机构31的趋势，保证锁止效果，当处于解锁状态时，限位弹簧322可通过弹性作用将推杆2上的夹持部21伸出壳体1，便于更换清洁头。
所述的夹持部21截面呈镊子型。截面呈镊子型的夹持部21，一端容易夹紧清洁部，另一端容易被壳体1压紧收缩。
所述的夹持部21具有弹性可收缩和复原。通过设置具有弹性的夹持部21，可在轴向移动过程中被壳体1压紧收缩或复原，对于清洁头的夹持和更换更加 方便。
所述的推杆2上设有便于推动其运动的推孔22，所述的壳体1上设有供使用者伸入推孔22的让位孔13。通过设置推孔22便于使用者推动推杆2进行更换清洁头或夹紧清洁头并进行锁止，通过设置让位孔13供使用者伸入推孔22。
本实用新型工作原理：本实用新型未使用时，处于解锁状态，使用时，先将清洁头放置于夹持部21中间，然后从推孔22处推动推杆2克服限位弹簧322的弹力使其朝远离清洁头的一侧运动，此时夹持部21受到导向部11的导向和挤压逐渐收缩夹紧清洁头，推杆2上的锁止部33随推杆2一起运动，直至锁止部33上的第一导向斜面331与按钮311上的第二导向斜面313相接触，锁止部33从按钮311底部滑过，然后停止推动推杆2，推杆2受到限位弹簧322朝向清洁头一侧的弹力，推杆2上的锁止部33顶压按钮311完成锁止；锁止状态下需要更换清洁头时，按压按钮311，即可使得按钮311端部与锁止部33分离，锁止部33无法对其限位，推杆2受到限位弹簧322的弹力直接朝夹持部21一侧运动，夹持部21随推杆2运动伸出壳体1逐渐复原，此时原有的清洁头掉落，可清洗和更换新的清洁头。
本实用新型通过设置锁定装置3可使推杆2在轴向方向快速锁止或解除其锁止，推杆2的轴向活动可带动夹持部21快速夹紧清洁头，更换方便，效率高，且无需在壳体1端部安装固定件321对夹持头和清洁头固定，节省了大量时间；通过第一导向斜面331和第二导向斜面313的相互配合可以使得锁止部33随推杆2快速轴向移动至按钮311下与其相抵锁止；通过在固定件321与推杆2之间设置限位弹簧322来使推杆2上的锁止部33始终具有顶压按压机构31的趋势，保证锁止效果，当处于解锁状态时，限位弹簧322可通过弹性作用将推杆2上的夹持部21伸出壳体1，便于更换清洁头；通过设置推孔22便于使用者推动推杆2进行更换清洁头或夹紧清洁头并进行锁止，通过设置让位孔13供使用者伸入推孔22。
本文中所描述的具体实施例仅仅是对本实用新型精神作举例说明。本实用新型所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本实用新型的精神或者超越所附权利要求书所定义的范围。
