具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的，并不表示是唯一的实施方式。
参阅图1、图2和图3，本发明一实施例提供的喷雾器10可以作为医疗器械使用，盛放有医用药液的储液瓶20可以放置在该喷雾器10内。工作时，喷雾器10可以将储液瓶20中的药液雾化形成液雾，用户可以通过吸收该液雾而达到摄取药液的目的。储液瓶20还以盛放非药液的其它液体等。喷雾器10主要包括壳体组件100、驱动组件200、顶撑盘300和计数盘400。
参阅图3、图4和图5，在一些实施例中，壳体组件100与储液瓶20间隔设置，使得壳体组件100与储液瓶20并未形成直接接触和连接关系。壳体组件100包括固定壳110和顶盖120，固定壳110大致呈轴向长度较大的圆筒状结构，为描述方便起见，将垂直于整个喷雾器10轴向的方向通俗理解为喷雾器10的径向，固定壳110沿喷雾器10的径向与储液瓶20间隔一定距离。顶盖120设置在固定壳110的端部，顶盖120沿喷雾器10的轴向可以与储液瓶20间隔一定的距离。
固定壳110包括凸台111和承载环112，凸台111和承载环112均凸出设置在固定壳110的内壁面上，使得凸台111和承载环112沿喷雾器10的径向相对该内壁面凸出一定的长度。凸台111和承载环112两者沿喷雾器10的 轴向间隔设置。凸台111的数量为多个，多个凸台111沿固定壳110的周向排列。凸台111的轴向顶部设置导向齿1111，导向齿1111具有竖直导向面1111a和倾斜导向面1111b，竖直导向面1111a和倾斜导向面1111b两者的一端相互连接。固定壳110的轴向与喷雾器10的轴向相同，竖直导向面1111a可以沿喷雾器10的轴向延伸，倾斜导向面1111b可以相对喷雾器10的轴向倾斜一定的角度，使得竖直导向面1111a和倾斜导向面1111b两者呈锐角设置。对于相邻的两个导向齿1111，其中一个导向齿1111的倾斜导向面1111b的端部与另外一个导向齿1111的竖直导向面1111a相接触，使得相邻两个导向齿1111形成相互接触的关系。相邻两个导向齿1111之间的间隙将形成导向槽1112，具体而言，其中一个导向齿1111的倾斜导向面1111b和另外一个导向齿1111的竖直导向面1111a共同围成该导向槽1112，即相邻两个导向齿1111的倾斜导向面1111b和竖直导向面1111a围成导向槽1112。在其他实施例中，相邻两个导向齿1111的倾斜导向面1111b和竖直导向面1111a可以不接触，从而使得相邻两个导向齿1111不接触而间隔设置。
凸台111的内壁面上开设有滑槽1113，该滑槽1113沿喷雾器10的轴向延伸，且该滑槽1113贯穿倾斜导向面1111b，使得该滑槽1113在倾斜导向面1111b上存在开口1114。
承载环112沿固定壳110的周向延伸而呈环状，承载环112靠近固定壳110的位于底部的端部设置。例如，承载环112可以在周向上连续分布而成闭环状，又如，承载环112也可以分为在周向上离散设置的多段弧条，相邻两段弧条在周向上间隔一定的距离。
参阅图1和图2，固定壳110上还开设有视窗孔113，该视窗孔113为通孔，使得视窗孔113沿径向贯穿整个固定壳110。固定壳110还包括指示部114，该指示部114设置在视窗孔113的边缘，例如，指示部114凸出设置在该视窗孔113的孔壁面上，且指示部114沿喷雾器10的轴向相对该孔壁面凸出一定的长度。
参阅图2、图3和图8，在一些实施例中，驱动组件200包括转轴210和套筒220，套筒220固定套设在转轴210上，使得套筒220无法相对转轴210产生滑动和转动，继而使得转轴210和套筒220两者保持同步运动，套筒220和固定壳110沿喷雾器10的轴向排列，套筒220能够与用户直接接触，用户可以直接对套筒220施加扭矩，使得套筒220带动转轴210同步转动。
转轴210包括轴部211、凸环部212和顶推部213，整个转轴210可以一体成型，转轴210的轴向与及整个喷雾器10的轴向相同。轴部211大致呈管状结构，轴部211可以环绕储液瓶20设置，轴部211沿喷雾器10的径向与储液瓶20间隔设定距离，使得轴部211和储液瓶20两者形成非接触关系。 凸环部212可以为圆环状，凸环部212套设在轴部211上，凸环部212沿喷雾器10的径向相对轴部211的表面凸出一定的长度。安装时，固定壳110环绕转轴210设置，该凸环部212承载在固定壳110的承载环112上，承载环112将对凸环部212和整个转轴210的安装起到轴向限位作用，转轴210可以绕自身的中心轴线相对固定壳110产生转动。顶推部213设置在凸环部212上，顶推部213沿喷雾器10的轴向相对凸环部212的表面凸出一定的长度，顶推部213具有第一斜面2131，该第一斜面2131相对喷雾器10的轴向倾斜一定的角度，使得第一斜面2131与喷雾器10的轴向呈锐角设置。顶推部213的数量可以为两个，两个顶推部213沿轴部211的周向间隔180°。顶推部213的数量还可以三个或三个以上，当顶推部213的数量为三个或三个以上时，全部顶推部213沿轴部211的周向均匀间隔设置，使得任意相邻两个顶推部213沿轴部211的周向所间隔的角度相等。
参阅图3、图4和图9，在一些实施例中，顶撑盘300可以大致呈轴向长度较小的圆筒状结构，顶撑盘300的轴向与喷雾器10的轴向相同。顶撑盘300套设在固定壳110之内，使得固定壳110环绕顶撑盘300设置，且顶撑盘300环绕转轴210的轴部211设置。顶撑盘300包括顶撑齿310、止挡部320和凸条330。顶撑齿310和止挡部320分别位于顶撑盘300轴向上的相对两端，显然，止挡部320位于顶撑盘300径向上的边缘位置处。顶撑齿310的数量为多个，多个顶撑齿310沿顶撑盘300的周向排列。顶撑齿310具有两个顶撑斜面311，两个顶撑斜面311的一端相互连接，两个顶撑斜面311均可以相对喷雾器10的轴向倾斜一定的角度，使得同一顶撑齿310上的两个顶撑斜面311连接形成锐角。对于相邻的两个顶撑齿310，其中一个顶撑齿310的顶撑斜面311的端部与另外一个顶撑齿310的顶撑斜面311的端部相互连接，使得相邻两个顶撑齿310形成相互接触的关系。相邻两个顶撑齿310之间的间隙形成顶撑槽312，具体而言，其中一个顶撑齿310的顶撑斜面311与另外一个顶撑齿310的顶撑斜面311共同围成该顶撑槽312，即相邻两个顶撑齿310的两个顶撑斜面311围成顶撑槽312。顶撑齿310用于推动计数盘400运动。
凸条330设置在顶撑盘300的外侧面上，凸条330沿喷雾器10的轴向延伸，凸条330相对顶撑盘300的外侧面沿喷雾器10的径向凸出一定的长度，凸条330的数量为多个，多个凸条330沿顶撑盘300的周向间隔设置，凸条330与固定壳110上的滑槽1113的数量相等，使得凸条330与滑槽1113形成一一对应关系，凸条330与滑槽1113滑动配合，使得整个顶撑盘300能够沿喷雾器10的轴向相对固定壳110滑动。
顶撑盘300具有呈环状的端面340，该端面340环绕顶撑盘300的轴线 设置，止挡部320凸出设置在顶撑盘300的端面340上，使得止挡部320相对该端面340沿喷雾器10的轴向凸出一定的长度。止挡部320具有第二斜面321，该第二斜面321相对喷雾器10的轴向倾斜一定的角度，使得第二斜面321与喷雾器10的轴向呈锐角设置，第二斜面321与上述顶推部213的第一斜面2131相对喷雾器10的轴向所倾斜的角度可以相等。止挡部320的数量与顶推部213的数量相等，使得止挡部320与顶推部213形成一一对应关系。止挡部320的数量可以为两个，两个止挡部320沿顶推盘的周向间隔180°。止挡部320的数量还可以三个或三个以上，当止挡部320的数量为三个或三个以上时，全部止挡部320沿顶撑盘300的周向均匀间隔设置，使得任意相邻两个止挡部320沿顶撑盘300的周向所间隔的角度相等。装配完成之后，止挡部320与顶撑盘300的端面340抵接，止挡部320可以与凸环部212抵接，使得凸环部212与顶撑盘300的端面340沿喷雾器10的轴向间隔一定的距离。
在其他实施例中，相邻两个顶撑齿310的两个顶撑斜面311可以不接触，从而使得相邻两个顶撑齿310不接触而间隔设置。顶撑盘300的顶撑齿310也可以用其他杆状结构进行替换，只要使得顶撑盘300能够推动计数盘400运动即可。顶撑盘300也可以套设在固定壳110之外，使得顶撑盘300环绕固定壳110设置。
参阅图3和图4，工作时，可以顺时针转动套筒220，使得套筒220带动转轴210顺时针运动，当顶推部213与顶撑盘300的端面340抵接时，顶推部213无法推动顶撑盘300相对固定壳110滑动。当转轴210的顶推部213与顶推盘的止挡部320接触时，第一斜面2131和第二斜面321将相互接触，鉴于第一斜面2131和第二斜面321两者均相对喷雾器10的轴向倾斜一定的角度，一方面使得顶推部213对止挡部320产生沿喷雾器10轴向的分力，该分力实际为顶推部213对顶撑盘300的顶推力，从而使得顶推部213推动整个顶撑盘300向上相对固定壳110滑动，使得止挡部320向上逐渐远离转轴210的凸环部212；由于凸条330与滑槽1113滑动配合，可以提高顶撑盘300相对固定壳110滑动的顺畅度，减少顶撑盘300向上滑动过程中所产生的晃动和卡滞现象。另一方面在顶撑盘300逐渐向上运动的过程中，可以为转轴210的转动提供避位空间，有效避免止挡部320对转轴210的转动构成阻碍。在顶推部213越过止挡部320而停止接触的瞬间，顶推部213将丧失对顶撑盘300的支撑作用，使得顶撑盘300能够在自身重力的促进作用下向下滑动，继而可以使得止挡部320逐渐靠近凸环部212运动直至与凸环部212相抵接。在其他一些实施方式中，也可以用弹性件抵压顶撑盘300，并通过弹性力使其快速复位；具体的，弹性件可以为弹簧同轴套设喷雾器10的转轴210外侧。
因此，通过对顶推部213和止挡部320两者的数量进行合理设置，在转轴210的持续顺时针转动的过程中，可以使得转轴210周期性推动顶撑盘300相对固定壳110向上滑动，继而使得顶撑盘300周期性相对固定壳110做上下往复运动。例如，当顶推部213和止挡部320两者的数量均为两个时，转轴210每转动180°即可推动顶撑盘300相对固定壳110形成一次上下往复运动。再如，当顶推部213和止挡部320两者的数量均为三个时，转轴210每转动120°即可推动顶撑盘300相对固定壳110形成一次上下往复运动。
参阅图3、图10和图11，在一些实施例中，计数盘400可以大致呈轴向长度较小的圆筒状结构，计数盘400的轴向与喷雾器10的轴向相同。计数盘400套设在固定壳110之内，使得固定壳110环绕计数盘400设置，且计数盘400环绕转轴210的轴部211设置。计数盘400包括转动齿410和凸起部420，转动齿410和凸起部420分别位于计数盘400轴向上的相对两端。转动齿410的数量为多个，多个转动齿410沿计数盘400的周向排列。转动齿410具有竖直转动面411和倾斜转动面412，竖直转动面411和倾斜转动面412两者的一端相互连接，竖直转动面411可以沿喷雾器10的轴向延伸，倾斜转动面412可以相对喷雾器10的轴向倾斜一定的角度，使得竖直转动面411和倾斜转动面412两者呈锐角设置。
对于相邻的两个转动齿410，其中一个转动齿410的倾斜转动面412与另外一个转动齿410的竖直转动面411互不接触而沿计数盘400的周向间隔设定距离，使得相邻两个转动齿410形成互不接触的关系，即相邻两个转动齿410在计数盘400的周向间隔设置。相邻两个转动齿410之间的间隙将形成收容槽414，具体而言，计数盘400还具有端面413，该端面413位于相邻两个转动齿410之间，转动齿410沿喷雾器10的轴向相对端面413凸出一定的长度；对于相邻两个转动齿410，端面413的一端与其中一个转动齿410的竖直转动面411连接，端面413的另一端与另外一个转动齿410的倾斜转动面412连接，使得端面413、其中一个转动齿410的倾斜转动面412和另外一个转动齿410的竖直转动面411三者共同围成该收容槽414，参阅图6和图7，固定壳110的导向齿1111能够与该收容槽414配合，转动齿410可以同时与顶撑槽312和导向槽1112配合。在其他实施例中，相邻两个转动齿410的倾斜转动面412和竖直转动面411接触，从而使得相邻两个转动齿410相互接触。
凸起部420相对计数盘400的主体部分沿喷雾器10的轴向凸出一定的长度，凸起部420具有第三斜面421，该第三斜面421相对喷雾器10的轴向倾斜一定的角度，该倾斜角度小于90°。计数盘400还设置有刻度标识430，刻度标识430位于计数盘400的外侧面上，例如刻度标识430可以为设置在 该外侧面上的沉槽，该沉槽沿喷雾器10的轴向延伸一定的距离。刻度标识430的数量可以为多个，多个刻度标识430沿计数盘400的周向均匀间隔排列，使得任意相邻两个刻度标识430之间沿计数盘400周向的间隔角度相等。计数盘400上还可以设置与相应刻度标识430对应的计数，上述计数的最大值可以为70，最小值为0。在其它实施例中，刻度标识430还可以为设置在计数盘400的外侧面上的凸起或刻度线等。
参阅图1，固定壳110上的视窗孔113可以将计数盘400上的部分刻度标识430暴露在外，用户可以直接观察到视窗孔113中的刻度标识430，指示部114将指向特定的刻度标识430，从而使得用户判定迅速并准确判断储液瓶20中药液的剩余量，继而使得用户准确判断药液的摄取量。例如，当指示部114指向计数为70的刻度标识430时，储液瓶20中药液为70单位剂量，当指示部114指向计数为0的刻度标识430时，储液瓶20中药液为0单位剂量，当指示部114指向计数为N的刻度标识430时，储液瓶20中药液为N单位剂量。当然，在指示部114指向70的刻度标识430时，可以意味着储液瓶20处于饱和的满瓶状态，此时，储液瓶20的液体并未产生任何消耗。当指示部114指向0的刻度标识430时，意味着储液瓶20处于完全空瓶状态，此时，储液瓶20的液体被全部消耗殆尽。
参阅图1、图2和图4，在一些实施例中，计数盘400上开设有第一孔440，第一孔440为通孔并沿径向贯穿计数盘400。例如，第一孔440可以开设在计数最大的刻度标识430的延长线上，转轴210的轴部211上开设有第二孔2112。第二孔2112口径可以大于第一孔440的口径，第一孔440可以为圆形孔，第二孔2112可以为长条形孔。当新的处于满瓶状态的储液瓶20装入至喷雾器10之后，第一孔440处于视窗孔113的覆盖范围之内，且第一孔440和第二孔2112相互对齐，此时可以确保指示部114刚好指向计数最大的刻度标识430，表明储液瓶20处于满瓶的初始状态。因此，在对喷雾器10装入满瓶状态的储液瓶20的过程中，用户必须调整计数盘400相对转轴210的位置关系，当用户通过第一孔440可以看到第二孔2112时，第一孔440和第二孔2112相互对齐，计数盘400和转轴210对位准确，指示部114刚好指向计数最大的刻度标识430。
进一步地，为提高操作的便捷性，喷雾器10还可以包括定位件510，该定位件510能够同时插入或拔出第一孔440和第二孔2112。在对喷雾器10装入满瓶状态的储液瓶20的过程中，调整计数盘400相对转轴210的位置关系，当定位件510能同时插入至第一孔440和第二孔2112中时，计数盘400和转轴210对位准确，可以确保指示部114刚好指向计数最大的刻度标识430。如此可以有效避免通过肉眼判断第一孔440和第二孔2112是否对齐，而是通 过定位件510替代肉眼判断第一孔440和第二孔2112是否对齐，最终提高计数盘400和转轴210的对位效率。当新的处于满瓶状态的储液瓶20装入至喷雾器10之后，在喷雾器10使用时，为防止定位件510对转轴210的转动构成干涉，用户可以直接用手拔出插入至第一孔440和第二孔2112中的定位件510，也可以通过强磁铁将定位件510从第一孔440和第二孔2112中吸出。
参阅图3和图4，在一些实施例中，喷雾器10还包括弹性卡条520，弹性卡条520可以抵压在壳体组件100和转轴210的轴部211之间，弹性卡条520的一端与壳体组件100的顶盖120滑动连接，弹性卡条520的另一端为自由端并与轴部211的表面相抵接。轴部211上开设有凹槽2111，该凹槽2111可以沿喷雾器10的轴向延伸一定的长度。在初始状态下，弹性卡条520的自由端与凹槽2111在喷雾器10轴向上所处的位置间隔一定的距离，可以通俗理解为凹槽2111位于弹性卡条520的自由端的上方。在转轴210的转动过程中，当储液瓶20中依然存在药液时，弹性卡条520无法与凹槽2111配合而对轴部211进行周向定位，使得弹性卡条520的自由端不会对轴部211的转动构成阻碍。鉴于计数盘400包括凸起部420，凸起部420具有第三斜面421。在转轴210的转动过程中，当储液瓶20中的药液消耗殆尽时，凸起部420将转动到与弹性卡条520相对应的位置，凸起部420的第三斜面421将与弹性卡条520抵接，第三斜面421将对弹性卡条520产生向上运动的顶推力，继而使得弹性卡条520相对壳体组件100向上滑动一定距离，轴部211的凹槽2111刚好转动至与弹性卡条520的自由端所对应的位置，此时，弹性卡条520释放能量，最终使得弹性卡条520的自由端卡入至凹槽2111中，弹性卡条520对轴部211形成周向定位作用，从而防止转轴210继续产生转动。因此，在喷雾器10的使用过程中，只要转轴210无法转动时，意味着储液瓶20中的药液全部消耗。
在一些实施例中，喷雾器10还包括弹性件530，弹性件530套设在转轴210的轴部211上，弹性件530的两端分别与顶盖120和计数盘400相抵接。弹性件530所产生的弹力，以及顶撑盘300和计数盘400自身的重力，可以使得顶撑盘300和计数盘400向下运动。
下面介绍喷雾器10的工作原理：
参阅图3、图6和图7，用户通过套筒220带动转轴210产生转动，当顶推部213与顶撑盘300的端面抵接时，顶推部213无法推动顶撑盘300相对固定壳110滑动，顶撑盘300处于静止状态，此时，转动齿410同时收容在顶撑槽312和导向槽1112中，导向齿1111收容在收容槽414中，转动齿410的竖直转动面411与导向齿1111的竖直导向面1111a贴合，转动齿410的倾斜转动面412与导向齿1111的倾斜导向面1111b贴合，顶撑齿310与转动齿 410的倾斜转动面412相抵接。当顶推部213的第一斜面2131与止挡部320的第二斜面321相抵接时，顶推部213将推动顶撑盘300相对固定壳110向上运动，继而使得顶撑齿310通过转动倾斜面推动转动齿410和整个计数盘400向上运动。在转动齿410向上运动的过程中，转动齿410的倾斜转动面412逐渐远离导向齿1111的倾斜导向面1111b，转动齿410沿着竖直导向面1111a的延伸方向向上运动，向上运动的计数盘400将对弹性件530产生挤压作用，使得弹性件530储存能量。
当转动齿410的端部向上运动至导向齿1111的端部时，第一斜面2131即将脱离第二斜面321，此时，在弹性件530弹力的作用下，加上倾斜导向面1111b对倾斜转动面412的导向作用，使得转动齿410脱离其中一个导向槽1112而进入至相邻的另外一个导向槽1112中。在转动齿410从一个导向槽1112进入至相邻的另一个导向槽1112的过程中，第一斜面2131脱离第二斜面321，在重力和弹性件530弹力的作用下，顶撑盘300和计数盘400两者均向下滑动，在计数盘400向下滑动的同时，计数盘400将产生转动，显然，在计数盘400向上滑动的过程中，喷雾器10不会喷出药液，而在计数盘400转动的过程中，计数盘400的转动将触发喷雾器10将储液瓶20中的药液喷出一定的剂量，当计数盘400停止转动时，计数盘400停止触发喷雾器10喷出药液，指示部114将指向新的刻度标识430(参阅图1)。因此，计数盘400每转动一次时，通过指示部114所指向的刻度标识430，用户可以准确知悉计数盘400每转动一次时喷雾器10所喷出药物的剂量，也准确知悉储液瓶20中剩余药液的剂量。
举例而言，在计数盘400转动之前，指示部114指向一个刻度标识430，该刻度标识430记为第一刻度标识，该第一刻度标识对应的计数为55，此时储液瓶20中剩余55单位剂量的药液。当转动转轴210而使计数盘400转动一次后，指示部114指向下一个刻度标识430，该刻度标识430记为第二刻度标识，该第二刻度标识对应的计数为54，此时，储液瓶20中剩余54单位剂量的药液，故计数盘400在该次转动过程中，喷雾器10喷出1单位剂量的药物，即用户摄取1单位剂量的药物。因此，通过对转轴210的持续转动，并通过指示部114所指向的刻度标识430，可以准确获悉转轴210在该转动时间内喷雾器10所喷出的药液剂量，也准确获悉储液瓶20中剩余的药液剂量。
转轴210每转动设定角度即可推动顶撑盘300向上运动滑动一次，从而使得计数盘400转动一次，继而使得喷雾器10喷出一定剂量的药液。例如，在顶推部213数量为两个的情况下，转轴210每转动180°即可推动顶撑盘300向上运动滑动一次，并使得计数盘400转动一次，计数盘400转动一次 的角度可以是相邻两个或相邻多个刻度在周向上所间隔的角度。当计数盘400转动一次的角度为相邻两个刻度在周向上所间隔的角度时，喷雾器10在计数盘400每转动一次过程中所喷出的药物为1单位剂量。当计数盘400转动一次的角度为相邻三个或四个刻度在周向上所间隔的角度时，喷雾器10在计数盘400每转动一次过程中所喷出的药物为2单位剂量或3单位剂量。
当喷雾器10将储液瓶20中的药物全部喷出后，指示部114将指向计数0所对应的刻度标识430；同时，凸起部420将转动到与弹性卡条520相对应的位置，凸起部420将对弹性卡条520产生向上运动的顶推力，使得弹性卡条520相对壳体组件100向上滑动一定距离，继而使得弹性卡条520的自由端将插入至轴部211的凹槽2111中，从而使得整个转轴210起到锁止作用，用户将无法继续驱动转轴210产生转动。
在一些实施例中，导向齿1111的数量为刻度标识430所对应的最大计数除以奇数所得到的商值，顶撑齿310的数量也可以为刻度标识430所对应的最大计数除以奇数所得到的商值。通过该设置可以合理减少导向齿1111和顶撑齿310的数量，从而减少模具的加工难度，降低喷雾器10的制造成本，也提高计数盘400运动的顺畅度。示例性的，如最大设计计数值为69，按照最大比例设计，导向齿1122的数量为69个，前述的奇数值为1。进一步，为了减少模具的加工难度，降低喷雾器10的制造成本；前述奇数值为3，即最大设计计数值为69，导向齿1122的数量为23个。显然，导向齿1122的数量减小，但是同样实现了69个计数值的效果。同理，当最大设计计数为其他值时，还可以为对应的其他数值关系进行对应。如，最大计数值为60时，导向齿1122的数量可以为60、20、12等值。当然，导向齿1122的数量也不能太少，太少将影响转动的稳定性与顺畅性。因此，优选的，奇数值为1、3、5中的一个值。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
