示例性的,一实施例中,请参阅图1,储液器5和气泵3均位于前支撑11的下部位。也就是说,喷射装置2大致位于储液器5和气泵3的上方。如此,整体结构的重心较低,能够减小整体结构的振动和噪声。
示例性的,一实施例中,请参阅图1至图2,气泵3、进气管路4、储液器5和进液管路6均位于安装空间中。通过安装空间隐藏气泵3、进气管路4、 储液器5和进液管路6。

紧固件包括但不限于螺钉、螺栓或铆钉等等。
示例性的,一实施例中,请参阅图4至图6,安装耳23可以位于前支撑11的前侧。这样,便于作业人员从前支撑11的前侧将喷射部21插入安装孔11a中,安装耳23贴合前支撑11的前表面。如此,不仅便于装配喷射装置2,还能够避免安装耳23大面积接触液体例如干洗剂。
示例性的,一实施例中,请参阅图8,喷射装置2包括限位板24,前支撑11形成有安装孔11a,喷射部21穿设于安装孔11a中,限位板24的至少部分夹持于喷射部21的外周面和安装孔11a的孔壁面之间。

一实施例中,请参阅图4,主体部22沿衣物处理筒的轴向延伸。即,第二方向与衣物处理筒的轴向平行。示例性的,以衣物处理筒的轴向沿水平方向为例,主体部22沿水平方向延伸。如此,便于主体部22外接管路例如进气管路4。
一实施例中,请参阅图4,喷射部21与衣物处理筒的轴线之间的夹角α在20°至70°之间。夹角α是指喷射部21的中心线与衣物处理筒的轴线之间的夹角。示例性的,喷射部21可以为回转体结构,也就是说,喷射部21为沿其中心线对称的结构。示例性的,喷射部21与衣物处理筒的轴线之间的夹 角α可以为20°、25°、30°、40°、50°、55°、60°或70°等等。这样设计,喷射部21向下倾斜的角度适中,既可以避免喷雾口251a直接朝向衣物处理筒的下表面,又可以避免喷雾口251a直接朝向衣物处理筒的后表面,喷雾口251a喷出的雾状液体例如干洗剂覆盖的面积可以更广。
示例性地,请参阅图4至图7,喷射装置2包括容设于进液腔21a中的雾化芯25,雾化芯25形成有文丘里流道25a和负压流道25b,负压流道25b连通文丘里流道25a和进液腔21a,文丘里流道25a具有连通喷射口2a的喷雾口251a。示例性的,气流沿文丘里流道25a流动,以在负压流道25b中产生负压,进液腔21a中液体例如干洗剂在负压作用下进入文丘里流道25a中,文丘里流道25a中的气流冲击液体以使得液体雾化成雾状液滴,雾状液滴从喷雾口251a和喷射口2a喷出。
一实施例中,请参阅图4至图7,进液腔21a具有进液口211a,进液口211a位于负压流道25b沿文丘里流道25a中的气流的流动方向的上游。
示例性的,气流沿文丘里流道25a流动,以在负压流道25b中产生负压,液体例如干洗剂在负压作用下,通过进液口211a进入进液腔21a中先预雾化成气液混合物。进液腔21a中的气液混合物通过负压流道25b进入文丘里流道25a中产生雾状液滴,雾状液滴从喷雾口251a和喷射口2a喷出。
本实施例中,通过文丘里流道25a中气流的流动产生负压,以便液体在负压作用下通过进液口211a进入进液腔21a。即利用文丘里流道25a的文丘里效应产生负压从而吸入液体。由于进液口211a位于负压流道25b沿文丘里流道25a中的气流的流动方向的上游,液体在文丘里流道25a产生的负压作用下通过进液口211a进入进液腔21a,如此,液体先与进液腔21a中的空气混合,以被分散成气液混合物,实现液体的预雾化,预雾化后的气液混合物再通过负压流道25b进入文丘里流道25a中,文丘里流道25a中的高速气流冲击预雾化后的气液混合物,使得预雾化后的气液混合物被进一步分散成雾状液 滴。这样,通过进液腔21a的预雾化步骤,使得液体能够完全雾化,提高液体的雾化效果。
可以理解的是,进液接头22b与进液口211a连通,以便储液器5中的干洗剂依次通过进液管路6、进液接头22b与进液口211a进入进液腔21a中。
进气接头22a与文丘里流道25a连通,以便气泵中的气体依次通过进气管路4和进气接头22a进入文丘里流道25a中。
文丘里流道25a用于流通第一流体介质,例如气体;进液腔21a用于流通第二流体介质,例如,干洗剂。
一实施例中,请参阅图7,文丘里流道25a包括收缩段252a、喉管段253a和扩张段254a。
请参阅图7,沿第一流体介质的流动方向,收缩段252a的第一端的过流断面面积大于收缩段252a的第二端的过流断面面积,收缩段252a的第二端连通喉管段253a的第一端。示例性的,收缩段252a的第二端的过流断面面积等于喉管段253a的过流断面面积。
这里,第一流体介质先流经收缩段252a再流经喉管段253a。具体地,第一流体介质先流经收缩段252a的第一端再通过收缩段252a的第二端进入喉管段253a。由于收缩段252a的第一端的过流断面面积大于收缩段252a的第二端的过流断面面积,第一流体介质经过收缩段252a加速减压后进入喉管段253a中,喉管段253a中第一流体介质的流速大于收缩段252a的第一端的第一流体介质的流速,第一流体介质在喉管段253a中的气压小于水流在收缩段252a中的气压,喉管段253a的出口周围的气压较小,使得负压流道25b内产生负压,以驱动进液腔21a中的气液混合物通过负压流道25b进入文丘里流道25a。沿气流的流动方向,收缩段252a过流断面面积从第一端向第二端逐渐减小。如此,第一流体介质(例如气体)在收缩段252a中流速逐渐增大且气压逐渐减小,气压呈连续的变化趋势,能够减小第一流体介质的湍流 度。
示例性地,喉管段253a的任一位置处的过流断面面积均相等。经过收缩段252a提速降压的第一流体介质进入喉管段253a中,第一流体介质在喉管段253a中能够较为平稳流动,喉管段253a起到整流作用,以便第一流体介质保持较高的流速和较低的气压平稳流动。
沿第一流体介质的流动方向,扩张段254a的第一端的过流断面面积小于扩张段254a的第二端的过流断面面积,扩张段254a的第一端连通喉管段253a的第二端,扩张段254a的第二端形成喷雾口251a。示例性的,扩张段254a的第二端的过流断面面积大于或等于喉管段253a的过流断面面积。如此,喷雾口251a的面积大于喉管段253a的过流断面面积,使得雾状液滴例如雾状干洗剂能够呈发散例如呈瀑布状或圆锥状喷出喷雾口251a。
示例性地,扩张段254a的过流断面面积沿气流流动方向从第一端向第二端逐渐增大。如此,扩张段254a中的雾状液滴例如雾状干洗剂能够更稳定地增压,减少湍流和压损。
这里,气流先流经收缩段252a再流经喉管段253a和扩张段254a,最后通过喷雾口251a和喷射口2a喷出。由于收缩段252a的第二端的过流断面面积大于收缩段252a的第一端的过流断面面积,气流经过收缩段252a加速减压后进入喉管段253a中,喉管段253a中气流的流速大于收缩段252a的第一端的气流的流速,气流在喉管段253a中的气压小于水流在收缩段252a中的气压,喉管段253a的出口周围的气压较小,使得负压流道25b内产生负压,以驱动进液腔21a中的气液混合物通过负压流道25b进入文丘里流道25a。喷雾口251a的面积大于喉管段253a的过流断面面积,使得雾状液滴例如雾状干洗剂能够呈发散例如呈瀑布状或圆锥状喷出喷雾口251a和喷射口2a。
需要说明的是,过流断面是指与元流或总流所有流线正交的横断面,即垂直于流速簇例如气流或液流的面。当流线簇彼此不平行时,过流断面 为曲面;当流线簇为彼此平行直线时,过流断面为一平面。
一些实施例中,请参阅图7,负压流道25b的一端连通于喉管段253a沿气流的流动方向的下游,负压流道25b的另一端贯穿雾化芯25的外周面。示例性的,一实施例中,负压流道25b的一端连通于扩张段254a的第二端的外周部位。如此,喉管段253a沿气流的流动方向的下游的流速相对更快、气压更小,以便产生较大的负压。
一些实施例中,请参阅图6、图7以及图12,喷射部21包括壳体211和盖体212。
请参阅图12,壳体211形成有朝盖体212开口的开口槽,开口槽具有开口。盖体212可拆卸地盖设于开口,盖体212和壳体211共同限定出用于容纳雾化芯25的安装腔21c。也就是说,雾化芯25从开口置入安装腔21c后,也可以从安装腔21c中取出,盖体212可以从壳体211上拆卸下来。
一些实施例中,壳体211和雾化芯25为两个独立的零部件为例,装配过程中,将雾化芯25从开口置入安装腔21c中,盖上盖体212即可。当雾化芯25发生堵塞、老化等现象时,可以打开盖体212,将雾化芯25取出,更换新的雾化芯25即可。
一些实施例中,盖体212和雾化芯25为一个不可拆分的整体为例,装配过程中,在盖上盖体212时,同时将雾化芯25从开口置入安装腔21c中,固定盖体212即可。当雾化芯25发生堵塞、老化等现象时,更换新的雾化芯25和盖体212的整体构件即可。
本申请实施例的喷射装置2,盖体212的安装方向、雾化芯25的安装方向一致,均沿雾化芯25的长度方向进行装配,如此,便于雾化芯25和盖体212的装配和拆卸;便于更换、维修雾化芯25。
示例性地,请参阅图7、图10和图12,壳体211具有相互独立的第一流道22a”和第二流道22b”。其中,第一流道22a”和第二流道22b”可以分 别通入不同的流体介质。
示例性地,第一流道22a”用于通入气体,第二流道22b”用于通入液态干洗剂。即气体为第一流体介质,液态干洗剂为第二流体介质。第一流道22a”的末端连接雾化芯25内的流道,而文丘里流道25a为雾化芯25内的流道的至少一部分,第二流道22b”的末端连接进液腔21a。雾化芯25用于将液态干洗剂和气体进行气液混合,并将气液两相混合物雾化后从喷雾口251a喷出。
该实施例中,气体携带干洗剂,经喷射装置2雾化而喷向衣物,通过气体作为干洗剂的雾化载体,干洗剂的喷射过程不会增大衣物的含水率,使得衣物能够保持在较低的含水率水平,便于降低后续的烘干时间,缩短干洗程序的时间,既节能又能提升干洗效率;此外,气体可以便于干洗剂充分雾化,促进干洗剂变为高能活化分子使其无阻碍的进入微米级的纤维间隙,深层去污。
示例性地,雾化芯25的部分轴段的周向表面与安装腔21c的内壁之间间隔设置并形成进液腔21a,进液腔21a连通第二流道22b”的出口和雾化芯25的内部空间。
该实施例中,干洗剂从第二流道22b”进入进液腔21a,再顺着进液腔21a流动,最后进入雾化芯25的内部空间,在雾化芯25内与来自第一流道22a”的气体进行气液两相混合,如此,进液腔21a充当了干洗剂的流道的角色,将来自第二流道22b”的干洗剂引流至雾化芯25,避免再设置单独的通道,简化结构,使得喷射装置2的结构更加简单、紧凑;此外,干洗剂可以顺着雾化芯25的周向表面流动,能够较多的流动路径,便于干洗剂的流动。
示例性地,沿雾化芯25的长度方向,请参阅图11,进液腔21a包括预混区21a1和流量控制区21a2,预混区21a1的流通截面面积大于流量控制 区21a2的流通截面面积。流量控制区21a2的流通截面面积较小,用于控制进入雾化芯25的内部空间的干洗剂的流量,使得经流量控制区21a2流向雾化芯25内部的流量较为平稳,波动小,变化雾化芯25更加精准地控制干洗剂的雾化流量。
第二流道22b”的出口设置于预混区21a1的侧壁上,喷射装置具有进气微通道,进气微通道连通预混区21a1和喷射装置的外部环境,使得干洗剂能够在预混区21a1实现气液两相预混合。
第二流道22b”中的干洗剂基本为连续液相,液态干洗剂进入预混区21a1,在预混区21a1与预混区21a1内的空气进行一级预混,形成气液预混两相流。可以理解的是,当干洗剂进入雾化芯25的内部空间内,会与来自第一流道22a”的气流进行二级预混。该一级预混为二级预混提供了有利条件,便于干洗剂在二级预混时与空气进行较为充分的混合。
可以理解的是,随着进液腔21a中的气液两相流源源不断流向雾化芯25的内部空间,预混区21a1形成负压,将外部空气从进气微通道源源不断地吸入,实现连续干洗剂的连续预混。
示例性地,第二流道22b”的末端的延伸方向与雾化芯25的长度方向的夹角为30°~90°,例如,30°、35°、45°、60°、80°、90°等。
该实施例中,当液态干洗剂从第二流道22b”流向预混区21a1时,液态干洗剂在流动惯性的作用下,环绕雾化芯25螺旋前进,如此,液态干洗剂能够卷入更多的空间,形成细小的液珠,含气量更好,预混效果更好。
例如,一些具体实施例中,第二流道22b”的末端的延伸方向与雾化芯25的长度方向的夹角为40°~60°。请结合参阅图7和图11,雾化芯25具有文丘里流道25a、喷雾口251a以及负压流道25b,第一流道22a”连通至文丘里流道25a的入口,第二流道22b”通过进液腔21a连通负压流道25b。
文丘里流道25a的流体经喷雾口251a喷出。也就是说,第一流道22a”的 流体、第二流道22b”的流体在文丘里流道25a内汇流,并一起从喷雾口251a喷出。
例如,第一种流体介质通入第一流道22a”,并流经文丘里流道25a,在流经文丘里流道25a的过程中,基于文丘里效应,在负压流道25b产生负压,第二流道22b”中的第二种流体介质在负压作用下从第二流道22b”被吸入文丘里流道25a,第一种流体介质和第二种流体介质一起从雾化芯25的喷雾口251a喷出。
需要说明的是,请参阅图7,盖体212设置有喷射口2a,喷射口2a避让雾化芯25的喷雾口251a。
本申请实施例的喷射装置2,负压流道25b和喷雾口251a均集中在雾化芯25上,雾化芯25相当于文丘里管,其内部的流道以及喷雾口251a的尺寸、形状等决定了喷射的雾汽的形态、喷射速度,壳体211、盖体212和雾化芯25的装配误差对喷设效果的影响相对较小,因此,只要控制雾化芯25的批量一致性,即可使得喷射装置2具有较好的批量一致性。
示例性地,雾化芯25为金属件,也就是说,雾化芯25采用金属材料制成。如此,便于在制造过程中控制雾化芯25的尺寸,金属材料在加工过程中能够控制较好的尺寸精度和误差,保障雾化芯25的尺寸精度和批量一致性。
示例性地,雾化芯25为一体式结构。当然,雾化芯25也可以是分体式结构。
示例性地,请参阅图12,壳体211设置有第一容纳槽211b,第一容纳槽211b与开口连通,例如,第一容纳槽211b的一侧敞开并形成开口。第一容纳槽211b构成安装腔21c的至少一部分。该实施例中,雾化芯25的至少一部分容纳于壳体211的第一容纳槽211b中,第一容纳槽211b对至少雾化芯25起到限位,有利于提升雾化芯25的安装可靠性。
示例性地,请参阅图12,盖体212具有第二容纳槽212a,第二容纳槽212a和第一容纳槽211b沿雾化芯25的长度方向对接。请参阅图7和图10,雾化芯25的一部分插设于第一容纳槽211b中,雾化芯25的另一部分插置于第二容纳槽212a中。也就是说,第一容纳槽211b和第二容纳槽212a共同限定出用于安装雾化芯25的安装腔21c,如此,盖体212和壳体211共同容纳雾化芯25,兼顾壳体211和盖体212在雾化芯25长度方向上的尺寸。
盖体212在第一容纳槽211b和第二容纳槽212a中的安装定位方式不限。
示例性地,请参阅图12,第一容纳槽211b的槽底具有环绕第一流道22a”的出口的第一定位面211d,第二容纳槽212a的槽底具有用于避让雾化芯25的喷雾口251a的喷射口2a以及环绕喷射口2a的第二定位面212b,盖体212与壳体211螺纹连接,且将雾化芯25的相对两端夹持在第一定位面211d和第二定位面212b之间。
在盖体212旋拧在壳体211上的过程中,第一定位面211d和第二定位面212b之间的距离逐渐减小,直至将雾化芯25的相对两端夹紧在第一定位面211d和第二定位面212b上。由于螺纹连接可以实现第一定位面211d和第二定位面212b之间的距离的连续调节,因此,无论雾化芯25的长度是否存在误差,盖体212和壳体211的螺纹连接均可以将雾化芯25夹紧在两者之间,消除雾化芯25的相对两端与第一定位面211d和第二定位面212b之间的间隙。
该实施例中,只需要盖体212和壳体211对雾化芯25进行夹持即可,无需使用螺钉等紧固件进行紧固。当拧下盖体212时,直接将雾化芯25从第一容纳槽211b的开口抽出即可。当需要装配时,将雾化芯25从开口插入第一容纳槽211b,随后拧紧盖体212即可,拆卸和装配均比较便捷。
示例性地,请参阅图9,盖体212靠近壳体211的一端形成有具有螺纹 段2121,螺纹段2121从开口伸入第一容纳槽211b内,且与第一容纳槽211b的内壁上的内螺纹配合。
另一些实施例中,也可以是壳体211靠近盖体212的一端设置有外螺纹,盖体212的内壁设置有内螺纹,盖体212套设在壳体211的周向外侧。
示例性地,请参阅图12,第一容纳槽211b的槽底具有定位环台2111,第一定位面211d环绕定位环台2111,定位环台2111的周向表面与第一容纳槽211b的周向内壁限定出环形插槽211c,请结合参阅图7和图10,雾化芯25的一端插设于环形插槽211c中。可以理解的是,文丘里流道25a沿长度方向贯穿雾化芯25,当雾化芯25插设在环形插槽211c后,第一流道22a”的出口22a”’和文丘里流道25a的入口对准且连通。
需要说明的是,第一容纳槽211b的槽底指的是第一容纳槽211b远离开口的一侧。
该实施例中,定位环台2111对雾化芯25起到更好的定位作用,防止雾化芯25在第一容纳槽211b中沿垂直于雾化芯25长度方向的任意一侧窜动,在装配过程中,也能使得雾化芯25准确地插入正确的位置,便于文丘里流道25a的入口对准第一流道22a”的出口22a”’。
示例性地,请参阅图9,雾化芯25靠近第一流道22a”的出口22a”’的一端的周向外表面设置有环槽25c,即环槽25c环绕雾化芯25的外部的周向表面。喷射装置2包括密封圈26,密封圈26设置于环槽25c中,且与第一容纳槽211b的周向内壁密封抵接。密封圈26能够加强雾化芯25和第一容纳槽211b的周向内壁的密封性能,降低第一流道22a”中的流体沿着雾化芯25和第一容纳槽211b的周向内壁之间的间隙窜入第二流道22b”的几率。
示例性地,请参阅图6和图9,沿第一流道22a”的流体流动方向,雾化芯25包括依次设置的入口轴段251、缩颈轴段252及出口轴段253。缩颈轴段252的外径小于入口轴段251的外径,也小于出口轴段253的外径。 也就是说,雾化芯25大致呈两端大中间小的构造。
入口轴段251插入第一容纳槽211b中,入口轴段251的外表面与第一容纳槽211b的周向内壁密封配合。例如,入口轴段251插入上述的环形插槽211c中。上述的环槽25c设置于入口轴段251的周向表面。
出口轴段253插入第二容纳槽212a中,负压流道25b设置于出口轴段253,第二流道22b”的出口11b″设置于第一容纳槽211b的周向内壁上。
缩颈轴段252与安装腔21c的周向内壁之间的间隙为第一间隙,出口轴段253与第二容纳槽212a的周向内壁之间的间隙为第二间隙,其中,第一间隙大于第二间隙。
请参阅图11,缩颈轴段252的周向表面和安装腔21c的周向内壁之间的区域形成预混区21a1,第二流道22b”的出口11b″设置于预混区21a1的侧壁上,即设置于第一容纳槽211b对应于预混区21a1的长度范围内的侧壁上。
示例性地,缩颈轴段252的横截面面积为第一定值;出口轴段253的横截面面积为第二定值,第二定值大于第一定值。
请参阅图6和图9,雾化芯25还包括连接部254,连接部254一端与缩颈轴段252连接,另一端与出口轴段253连接,连接部254的横截面面积从一端到另一端逐渐增大。其中,负压流道25b设置在出口轴段253远离连接部254的一端,雾化芯25内的流道贯穿入口轴段251、缩颈轴段252、连接部254和出口轴段253。由此,在连接部254的外侧壁与安装腔21c的内侧壁之间形成变径区域21a3。
第二流体介质在从缩颈轴段252外侧流至出口轴段253外侧的过程中,进液腔21a的横截面面积减小,有利于减小第二流体介质的流量,且雾化芯25的结构简单,加工制造方便,有利于降低生产的难度。
负压流道25b的数量不限,例如,可以是一个,也可以是多个。
示例性地,出口轴段253与第二容纳槽212a的周向内壁之间的区域的最小流通截面面积小于各负压流道25b的流通截面面积之和。如此,从第二流道22b”进入文丘里流道25a的总流量取决于出口轴段253与第二容纳槽212a的周向内壁之间的区域的最小流通截面面积,而该最小流通截面面积可以通过出口轴段253和第二容纳槽212a的侧壁之间的尺寸间隙来控制,负压流道25b本身的尺寸较小,在制造过程中,控制小的尺寸的精度较为困难,而该实施例中,通过出口轴段253和第二容纳槽212a之间的尺寸间隙来控制则容易得多,如此,能够降低制造精度要求和工艺要求,在保障喷射装置2的精度的情况下,降低成本。
示例性地,盖体212与壳体211的螺纹配合处形成与进液腔21a连通的进气微通道。也就是说,盖体212与壳体211的螺纹配合没有完全的气密密封,而是可以允许少量的气体从螺纹缝隙中流入第一容纳槽211b和第二容纳槽212a的对接处。
示例性地,壳体211和盖体212的螺纹对接处位于预混区21a1对应的侧壁上,也就是说,位于缩颈轴段252对应的安装腔21c的侧壁上。如此,在喷射过程中,外界的空气从螺纹对接处不断地被抽吸进入预混区21a1,使得从第二流道22b”进来的液体能够在预混区21a1与空气进行较好的预混。
以上所述,仅为本申请的具体实施方式,但本申请的保护范围并不仅限于此,任何熟悉本技术领域的技术人员在本申请揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本申请的保护范围之内。因此,本申请的保护范围应以所述权利要求的保护范围为准。
