具体实施方式
为使本发明解决的技术问题、采用的技术方案和达到的技术效果更加清楚,下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
实施例一
如图1所示,本实施例提供了一种吹风机,包括吹风筒100、与吹风筒100连接的手柄200以及与手柄200连接的电源线400。吹风筒100内形成有主风道,主风道内设置有加热组件123,吹风筒100上设置有与主风道连通的进风口101和出风口102,气流由位于吹风筒100后侧的进风口101进入主风道内,经过加热组件123加热后由出风口102排出,从而实现吹风机烘干和整形的目的。
如图2所示,吹风筒100包括外壳11,外壳11的左右两端开口,以便气流进入和吹出。外壳11的底部设置有安装口103,手柄200通过安装口103与吹风筒100连接。
如图3和图4所示,主风道靠近出风口102的位置设置有加热室12,加热室12内设置有加热组件123,加热组件123用于加热主风道内的气流。本实施例中,加热室12靠近出风口102设置,经加热组件123加热后的气体直接排除吹风筒100外,减小热量在主风道内的损失,可以在满足出风温度的基础上,降低吹风机的能耗。
吹风机内还包括鼓风组件13,用于在主风道内形成负压,以便吹风机外部的空气在压强的作用下进入主风道内。如图4所示,鼓风组件13包括风机和电控PCB板14,电控PCB板14与风机连接,用于控制风机启停等。风机可以包括电机和风扇,电机驱动风扇转动。可选地,电机可以为无刷电机。
现有技术中,为减小吹风筒100的尺寸,将鼓风组件13和电控PCB板14设置在手柄内,由于无刷电机自身尺寸以及需要搭配的电控PCB板14的尺寸均较大,导致手柄的长度和直径均较大,无论是日常使用还是外出携带均不方便,影响用户使用体验。
为解决上述问题,如图4所示,本实施例中,鼓风组件13设置在吹风筒100内,气流在风道内依次经过鼓风组件13和加热室12。可选地,加热室12和鼓风组件13可以通过导风罩15连通。本实施例中,通过在鼓风组件13位于吹风筒100内,以减小手柄的尺寸,用户握感更好,方便使用和携带。
为解决无刷电机需要搭配的电控PCB板14占用空间较大的问题,本实施例中,电控PCB板14为环形结构,其套设于鼓风组件13外。通过将电控PCB板14设置为环形,可以减小电控PCB板14占用的空间;电控PCB板14套设在鼓风组件13外,可以使吹风筒100内结构更加紧凑,有利于减小吹风筒100的尺寸。可选地,电控PCB板14可以分为两个环形控制板,减小电控PCB板14需要占用吹风筒100的径向尺寸,两个环形控制板之间可以通过连接筋连接,使得吹风筒100的结构更加紧凑。
具体地,如图4和图5所示,鼓风组件13包括风机,吹风筒100内设置有安装套筒18,安装套筒18包括筒状的风机连接部181以及连接于风机连接部181靠近进风口101一端的端盖182。安装套筒18的两端开口,风机位于安装套筒18内,以起到保护风机的作用。环形的电控PCB板14套设在安装套筒18内,避免风机与电控PCB板14直接接触。端盖182设置于安装套筒18靠近进风口101的一端,端盖182设置有中心孔,中心孔与吹风筒100的进风口101连通。风机的内部形成鼓风室,鼓风室与加热室12连通以形成主风道。
本实施例中,电控PCB板14套设在鼓风组件13外,即电控PCB板14位于主风道外,气流不与电控PCB板14接触,可以避免电控PCB板14在主风道内增加噪音,避免扰乱气流而产生湍流,提高气流在主风道内流通的顺畅性。
由于电控PCB板14位于主风道外,而电控PCB板14在工作时会产生大量热量,为方便电控PCB板14产生的热量散出,避免吹风筒100发热,电控PCB板14还连接有散热结构,散热结构可以将电控PCB板上的热量快速导出,以解决电控PCB板14设置在主风道外的散热问题。
具体地,散热结构包括散热组件,散热组件的一端与电控PCB板14上的发热元件接触, 另一端伸入主风道内,以便发热元件产生的热量散出。其中,散热组件可以与发热元件直接接触,也可以通过其他结构间接接触,只要是能传导热量即可。
散热组件与发热元件接触,发热元件上的热量能传递到散热组件上。散热组件的至少部分位于主风道内,通过自然风等温度低于散热元件温度的气流带走散热组件的热量,从而达到发热元件散热的效果。即,散热组件作为发热元件的辅助散热装置,能及时高效地导走发热元件上的热量,确保电控PCB板14等结构能正常运行,延长了产品的使用寿命,解决了现有吹风机中电控PCB板14无法良好散热的问题。
具体地,如图5和图6所示,安装套筒18上还可以设置有第一散热片191,第一散热片191的一端与电控PCB板14上的发热元件接触,另一端位于吹风筒100的进风口101内。发热元件产生的热量将通过热传导传递至第一散热片191上,经第一散热片191传递至其位于进风口101内的一端,随着气流进入进风口101,将第一散热片191上的热量带走。本实施例中,带走热量的气流将经过鼓风室进入加热室12内,利用了发热元件产生的热量,避免热量浪费。可选地,本实施例中发热元件可以为电控PCB板14上的MOS管或可控硅。
如图7所示,第一散热片191包括基座1911和设置在基座1911上的多片翅片1912,翅片1912从发热元件朝向进风端延伸设置。优选的,翅片1912朝着来风方向倾斜设置,在增大与气流的热交换面积的同时尽可能降低风阻,减小噪音。即,翅片1912的延伸方向与吹风机的进风方向是逆向的,从而令翅片1912能接触到更上游的、更低温的气流。
翅片1912包括远离进风端的底部、靠近进风端的顶部、处于迎风侧的前侧面、以及处于背风侧的后侧面。翅片1912的底部设置在基座1911上,结构更稳定;顶部必然是处于主风道内,其它结构是否处于主风道中则根据实际使用需求而定。本实施例中,翅片1912的顶部位于进风口101内。
沿进风方向,顶部与底部之间的距离逐渐减小,即,顶部为顺着进风方向倾斜的斜面,在不影响散热的情况下降低风阻,减小噪音。前侧面外凸呈拱形,即,类似于瓦片状,进风吹过前侧面时气流更平稳,噪音低。后侧面与顶部的连接处为弧面,即,后侧面与顶部光滑过渡连接,避免进风在后侧面与顶部的连接处被阻碍。
在基座1911上设置有台阶面1913,台阶面1913贴在发热元件上,热传导效率高。同时,台阶面1913也能在基座1911和发热元件之间起到相互限位的作用。
基座1911的具体形状不限,能为发热元件高效导热即可。优选的,基座1911为与发热元件上发热点对齐的扇形或与发热元件整体对齐的环形的片状结构。为环形时,散热面积大,散热效率高;为扇形时,体积小、重量轻,有利于吹风机实现小型化和轻型化。优选的,基座1911直接与发热元件上的发热点导热性连接,导热效率更高。
基座1911上不但与发热元件相贴合的部分能传到热量,其不与发热元件相贴合的部分亦能将发热元件周围空间中的热量快速导走,同样也起到了辅助发热元件散热的作用。
可选地,本实施例中,电控PCB板14为双层环形结构,电控PCB板14上的电器元件可以设置在双层环形结构的外侧的两个环形面上,其中靠近进风口101一侧的电器元件可以通过上述第一散热片191散热,另一侧由于远离进风口101,其上连接的散热组件很难伸入到进风口101内,散热效果差。
为解决上述问题,本实施例中,如图8和图9所示,散热组件还包括第二散热片192,第二散热片192位于电控PCB板14远离进风口的一侧。第二散热片192的一端与该侧电控PCB板14上的发热元件接触,另一端可以伸入到加热室12内,通过进入加热室12内的气流带走热量,实现散热。具体地,第二散热片192可以穿过导热罩15伸入到加热室12的上游,即导风罩15内,该侧气流温度较低,可以提高散热效率,且第二散热片192上的热量用于加热气流,提高热量利用率。
为减小第二散热片192与导风罩15之间存在的缝隙,第二散热片192与导风罩15之间还设置有堵风塞,堵风塞可以避免加热室12内的气体进入外壳11与主风道之间。
在上述结构的基础上,在散热组件与发热元件的间隙中填充有导热材料,令散热组件与发热元件可靠地导热性连接,避免因空气的隔离导致发热元件上热量无法传递到散热组件上。该导热材料可以为但不限于为导热硅脂,能保证高效地传递热量即可。
在其他实施例中,散热结构还可以为导风罩15,具体地,连接鼓风组件13和加热室12的导风罩15可以设置有导流结构,导流结构可以将由进风口101进入的部分气流导向电控PCB板14,以提高电控PCB板14的散热效果。具体地,导风罩15一端与鼓风组件13的安装套筒18连接,另一端与加热室12连接。导风罩15上设置有第一分流孔,鼓风组件13的端盖182上设置有第二分流孔,经过导风罩15的部分气流通过第一分流孔进入外壳11与鼓风组件13之间,以冷却电控PCB板14,吸收电控PCB板14热量的气流由第二分流孔流出,从而形成冷却电控PCB板14的循环风路。
为了避免使用吹风机后头发干燥、易起静电,吹风机还可以包括负离子发生器23,负离子发生器23可以生成空气负离子,随气流与头发接触,避免头发产生静电,从而使得头发更加柔顺,起到保养头发的目的。但现有的吹风机中负离子发生器23位于吹风筒100内,例如位于加热室12的外周面上,占用吹风筒100空间,使加热室12与外壳11之间的空隙较大,导致吹风筒100的尺寸较大。
为解决上述问题,本实施例中,如图10-图12所示,负离子发生器23设置在手柄200内,负离子发生器23的放电端231伸入到吹风筒100内。通过将负离子发生器23置于手柄200内,可以减小吹风筒100的尺寸,有利于减小加热室12与外壳11之间的尺寸,使得吹风筒100的结构更加紧凑,有利于减小吹风筒100的尺寸。
由于负离子在空气中存在的时间较短,为了缩短放电端231产生的负离子在主风道内时间,放电端231可以向吹风筒100的出风口102延伸,以使负离子尽快与头发接触。
可选地,放电端231可以位于吹风筒100的中心轴线上,一方面可以进一步提高吹风筒100内的空间利用率,另一方面还可以使负离子分布更加均匀。
具体地,加热室12包括外筒121和内筒122。外筒121的下游端设置有离子出口1211和出风口102。内筒122的两端开口,且设置于位于外筒121内,内筒122与外筒121之间设置有加热组件123,放电端231位于内筒122内,且朝向离子出口1211设置。气流经过鼓风室后进入内筒122与外筒121之间,在加热组件123的作用下升温的同时,放电端231工作产生负离子,负离子由离子出口1211排出后混入气流内,与头发接触消除静电。
为保护放电端231,放电端231外还设置有离子端盖232,避免加热室12内的部件与放电端231接触,以达到保护放电端231的目的。
可选地,加热组件123包括多个加热单元,每个加热单元沿内筒122的轴向延伸,多个加热单元沿内筒122的周向均布,从而提高加热的均匀性。为了避免热量通过外筒121散发,加热组件123还包括设置于外筒121内侧的隔热筒1232,隔热筒1232可以减少热量流失,提高热量利用率。
如图12所示,为方便用户使用吹风机,手柄200上还设置有开关按钮、风速调节按钮、风温调节按钮以及模式调节按钮等控制按钮26,以便控制吹风机的启停、风速、风温或选择合适的吹风模式。为了通过上述按钮实现对吹风机的控制,手柄200内还设置有主控PCB板24,主控PCB板24分别与鼓风组件13、加热组件123和负离子发生器23连接,以便根据用户的操作控制鼓风组件13和加热组件123。可选地,负离子发生器23可以设置于主控PCB板24的底部。
可选地,吹风机还可以包括多个风嘴,每个风嘴均与吹风筒100的出风口102可拆卸连 接,以便根据用户的不同使用需求更换风嘴。可选地,风嘴可以与吹风筒100通过卡扣结构连接、通过磁性件吸附固定或通过螺钉等紧固件连接。
现有技术中,将风机放入手柄200内的吹风机,例如戴森Supersonic HD01型吹风机,可以减小吹风筒100的尺寸,吹风筒100的直径和长度分别为78mm和97mm,但手柄200加长,手柄200长度为245mm。本实施例中,通过调整吹风机内各部件的结构和位置,可以减小吹风筒100的尺寸,使吹风筒100的长度不超过125mm,例如小于120mm,吹风筒100的直径不超过80mm,例如可以小于77mm,吹风筒100的尺寸可以与戴森Supersonic HD01型吹风机中吹风筒100的尺寸相差较小,且主风道不需经过手柄200,极大的缩短的主风道的长度,使得吹风机的效率显著提高。通过合理布局吹风筒100内的部件,手柄200的体积无需增大,手柄200的长度可以不超过125mm,直径不超过40mm,例如手柄200的长度可以缩短为170mm,直径缩小为38mm,相比现有技术的245mm,手柄200长度大幅度缩短。
实施例二
本实施例提供了一种吹风机,与实施例一不同的地方在于,吹风机内还设置有保护装置,从而防止吹风机过热。保护装置包括温度检测件17。如图4所示,温度检测件17可以设置在加热室12内。具体地,温度检测件17设置于内筒122的外周面上,主控PCB板24接收温度检测件17传输的信号,根据温度检测件17获得的温度值控制加热组件123间歇性关闭。
具体地,主控PCB板24包括存储单元、比较单元和执行单元,存储单元用于预存第一温度预设值和第二温度预设值,比较单元用于将温度检测件17获得的温度值与第一温度预设值和第二温度预设值比较。执行单元被配置为在吹风机处于烘干模式工作时,若温度检测件17获得的温度值高于第一温度预设值,则判断为过热,主控PCB板24控制加热组件123关闭停止发热、吹风机的鼓风组件13正常运转;在吹风机处于烘干模式工作且加热组件123处于停止状态时,若温度检测件17获得的温度值低于第二温度预设值,则主控PCB板24控制加热组件123重新开启。
当温度检测件17获得的温度值在第二温度预设值和第一温度预设值之间时,表示加热组件123的温度正常。在此,对第一温度预设值和第二温度预设值的大小不作限制,可根据实际情况设定。
在使用时,吹风机处于烘干模式时,鼓风组件13和加热组件123同时启动,以提供热风。在使用过程中,温度检测件17会实时检测加热组件123的温度,并将获得的信号传输至主控PCB板24,主控PCB板24获得加热组件123的当前温度值,并将当前温度值与第一温度预设值和第二温度预设值进行比较,若当前温度值在第二温度预设值和第一温度预设值之间,表示加热组件123的温度正常。
使用一段时间后,当加热组件123的温度值高于第一温度预设值时,则表示过热,主控PCB板24控制加热组件123关闭停止发热,以防止吹风机内温度过高烧毁吹风机的部件或者烫伤使用者,此时,鼓风组件13仍在正常运转,加热组件123的余温也能保证有热风产生。鼓风组件13能够对加热组件123降温,同时在加热组件123停止发热期间,加热组件123的余温也能保证有热风产生,不影响正常使用;待加热组件123温度降低到低于第二温度预设值时,主控PCB板24控制加热组件123重新开启。间歇性开启有利于加热组件123降温,且不影响正常使用。
主控PCB板24与加热组件123之间通过加热调控电路连接,加热调控电路上设置有可控硅,主控PCB板24控制可控硅的打开和关闭。可控硅关闭时,加热组件123的供电单元切断,加热组件123关闭停止发热,但是此时鼓风组件13正常运转。
实施例三
本实施例提供了一种吹风机,与实施例二不同的地方在于,主控PCB板24与鼓风组件 13以及能够检测鼓风组件13附近温度的一辅助温度检测件电连接,主控PCB板24根据辅助温度检测件获得的温度值控制总供电单元开闭。
若鼓风组件13的温度过高,则表示鼓风组件13工作时间过长或者非正常工作,主控PCB板24即刻关闭鼓风组件13的供电单元,因鼓风组件13停止运转,加热组件123单独工作而没有冷风通过势必造成过热,因此需同时切断加热组件123的电源。因此,当鼓风组件13的温度过高时,主控PCB板24需切断鼓风组件13和加热组件123的电源,即关闭总供电单元。
鼓风组件13与加热组件123并联,便于独立进行控制。温度检测件17和辅助温度检测件并联,防止检测结果之间的相互干扰。
主控PCB板24的存储单元内预存有第三温度预设值,辅助温度检测件获得的温度值高于第三温度预设值时,表示鼓风组件13的温度过高,则主控PCB板24关闭总供电单元。在此,对第三温度预设值的大小不作限制,可根据实际情况设定。
此时可能由于鼓风组件13长时间工作导致的过热或者鼓风组件13故障导致的过热,在吹风机静置一段时间进行降温后,操作者可以打开总开关进行检测。若再次打开时没有出风,则是鼓风组件13故障,便于及时进行维修;若再次打开时正常出风,则是上一次使用鼓风组件13时间过长。
温度检测件17和辅助温度检测件配合设置,对吹风机起到双重保护作用,防止其中一个故障导致的检测不准确。
实施例四
本实施例提供了一种吹风机,与实施例二不同的地方在于,在吹风机的出风口102处设置风速感应器,风速感应器与主控PCB板24电连接。风速感应器用于检测出风口102的风速,风速传感器与温度检测件配合,对吹风机进行多重保护。
在吹风机处于烘干模式时,当温度检测件17检测到加热组件123的温度过高,除了可能是加热组件123工作时间过长导致的,还有可能是鼓风组件13停转或者出风口堵塞导致的。此时,主控PCB板24控制加热组件123关闭停止发热,并根据风速感应器检测到的风速值进行综合判断。
若风速感应器获得的风速值低于风速预设值,表示鼓风组件13故障停转,主控PCB板24即可在关闭加热组件123的同时关闭鼓风组件13,即关闭总供电单元,并对鼓风组件13进行维修。此时,若风速感应器获得的风速值正常,表示鼓风组件13正常,主控PCB板24即可只关闭加热组件123,利用鼓风组件13对加热组件123散热,同时对出风口进行检查并处理。
因此,风速感应器的设置,能够更进一步确定吹风机所处的状态,进而采取更好的处理方式。在此,对主控PCB板24内预存的风速预设值的大小不作限制,可根据实际情况设定。
如果主控PCB板24判断吹风机存在故障,可根据故障的种类的不同通过不同颜色的报警灯进行提示,便于用户针对性维修。
实施例五
本实施例提供了一种吹风机,与实施例二不同的地方在于,电机上设置有转速传感器,转速传感器与主控PCB板24均电连接。转速传感器用于检测电机的转速,转速传感器与温度检测件配合,对吹风机进行多重保护。
在吹风机处于烘干模式时,当温度检测件17检测到加热组件123的温度过高,除了可能是加热组件123工作时间过长导致的,还有可能是鼓风组件13停转或者出风口堵塞导致的。此时,主控PCB板24控制加热组件123关闭停止发热,并根据转速传感器检测到的转速值进行综合判断。
若鼓风组件13的转速在转速预设范围内,则表示出风口可能堵塞,此时只关闭加热组件 123,利用鼓风组件13对加热组件123散热,同时对出风口进行检查并处理。若吹风机中安装有散热装置,此时可打开散热装置进行散热。或者,将吹风机静置进行散热。待吹风机冷却后,仍可再次使用。若鼓风组件13的转速异常,则表示鼓风组件13故障停转,此时主控PCB板24即可在关闭加热组件123的同时关闭鼓风组件13,即关闭总供电单元,并对鼓风组件13进行维修。
主控PCB板24的存储单元内预存有转速预设范围,转速传感器检测到的转速值与转速预设范围内的两个端点值进行比较,若转速值不在转速预设范围内,则表示鼓风组件13的转速异常。
若温度检测件17获得的温度值低于第二温度预设值时,此时在控制加热组件123开启之前,先确保转速传感器获得的转速值在转速预设范围内,表示鼓风组件13处在正常运转的状态下,再控制加热组件123开启,以确保安全性。
因此,转速传感器的设置,能够更进一步确定吹风机所处的状态,进而采取更好的处理方式。
实施例六
本实施例提供了一种吹风机,与上述实施例不同的地方在于,本实施例中手柄200内设置有副风道,副风道与主风道连通。
具体地,如图12所示,手柄200包括壳体21及连接件25。壳体21内形成副风道,壳体21的上端与吹风筒100上的安装口103连接,壳体21的下端通过连接件25与电源线400连接。连接件25可以为格栅结构,具有与壳体21内部连通的镂空区,镂空区可以作为副风道的气流进口。吹风机工作时,手柄200附近的空气在气压差的作用下由气流进口进入副风道内,经过手柄200内的主控PCB板24和负离子发生器23后进入主风道。通过设置副风道一方面可以增加吹风机内气流的稳定性,使其流动更顺畅,另一方面可以提高手柄200内电器元件的散热效果,避免吹风机使用时手柄200发热、发烫,提高用户的使用体验。
可选地,壳体21内还设置有做内壳体21,主控PCB板24和负离子发生器23设置在内壳体21内,内壳体21包括左壳221和右壳222,左壳221和右壳222可以通过螺钉固定。内壳体21可以起到保护主控PCB板24和负离子发生器23的目的,在维护主控PCB板24和负离子发生器23时,可以将内壳体21由壳体21内滑出,之后通过拆卸螺钉将左壳221和右壳222拆开,避免在拆装过程中损坏主控PCB板24和离子发生器。
实施例七
本实施例提供了一种吹风机,与上述实施例不同的地方在于,如图13所示,吹风筒100在进风口位置设置有保护罩111和过滤装置。具体地,吹风筒100的外壳11包括筒体以及位于进风口侧的保护罩11,保护罩11与筒体可拆卸连接,保护罩111内设置有过滤组件112,空气经过滤组件112进入到鼓风室内,过滤组件112能够将空气中的灰尘、头发等异物过有效去除,以起到净化空气、防止吹风筒100内风机缠绕卡死的效果。通过过滤组件112与保护罩111可拆卸连接,当过滤组件112使用时间较长,操作者可以先将保护罩111从吹风筒100上拆下,再将过滤组件112从保护罩111上拆下,再单独地对过滤组件112进行全面彻底的清洁,使清洁后的过滤组件112有较好的过滤效果。此外,通过过滤组件112与保护罩111可拆卸连接,若过滤组件112或保护罩111中的一个出现损坏,仅需要更换出现损坏的零部件即可,无需将过滤组件112和保护罩111同时替换,有效降低吹风机的维修成本。
如图13和图14所示,本实施例中的过滤组件112可以为过滤海绵或过滤网,过滤海绵或过滤网可以卡接在保护罩111的内壁上,以实现过滤海绵或过滤网与保护罩111的可拆卸连接,无需在过滤组件112与保护罩111之间设置额外的固定组件,简化吹风机的整体结构,提高过滤组件112与保护罩111的拆装效率。
此外,由于过滤海绵或过滤网的孔隙较小,过滤海绵或过滤网能过滤直径较小的灰尘以及细小的头发,可以防止直径较小的灰尘以及细小的头发进入到吹风筒100的风道中,改善了用户体验。优选地,过滤海绵的孔隙密度(PPI,Pores Per Linear Inch)不小于40PPI,过滤网的目数不小于40,能够保证过滤组件1123对灰尘、头发等异物的较好的过滤效果,且能保证过滤组件1123不会减少吹风机的进风量。其中,孔隙密度是指单位英寸长度上的平均孔数,目数是指过滤网在一英寸内的孔数。
如图14所示,保护罩111的一侧端面连接在筒体上,另一侧端面设置有进风格栅1111,进风格栅1111形成进风口101。进风格栅1111包括多根关于吹风筒100的轴线对称设置的立柱,进风格栅1111整体成镂空结构,在避免操作者手伸入吹风机内部的同时,保证空气较顺畅地进入到保护罩111的内部。
保护罩111内还设置有过滤罩113,过滤罩113上开设有多个过滤孔,空气依次穿过过滤组件112和过滤罩113,经过过滤组件112和过滤罩113的两级过滤,再进入到吹风筒100的风道中,较仅设置过滤组件112的方案相比,进一步提高了灰尘及头发的过滤效果。
吹风机在使用的过程中会产生震动,过滤组件112在震动的影响下可能会从保护罩111上掉落,有被搅入到吹风筒100内鼓风组件的风险,使鼓风组件中的风机缠绕卡死,导致风机被烧毁,影响用户使用安全。为解决上述技术问题,过滤罩113为开设多个过滤孔的不锈钢网罩,不锈钢网罩能将过滤组件112有效地阻隔在吹风筒100的外部,避免过滤组件112进入到鼓风组件内部,保证风机的正常运转,保证用户的使用安全。
过滤罩113朝向进风格栅1111凸起,能在过滤罩113上开设更多的过滤孔,使不锈钢网罩上多个过滤孔的横截面积之和大于鼓风组件的进风入口的横截面积,保证空气顺畅地进入到鼓风组件中,以使吹风机有较好的吹风效果。
为了减少吹风筒100的长度尺寸,在过滤组件112上开设有第一避让孔1124,至少部分过滤罩113容纳在第一避让孔1124中,使得过滤组件112与过滤罩113沿吹风筒100的长度方向的排布更紧凑,使吹风机的整体体积较小,便于吹风机的携带。
实施例八
本实施例公开一种吹风机,与实施例七不同的地方在于,如图15和图16所示,保护罩111的内壁沿周向凸设有多个卡块1112,卡块1112与进风格栅1111之间形成容纳过滤组件112的安装空间。通过设置卡块1112能够限制过滤组件112相对保护罩111沿保护罩111的轴线方向的运动,使过滤组件112与保护罩111的固定效果更好。为了进一步提高卡块1112对过滤组件112的限位效果,可以将多个卡块1112设置为沿保护罩111的周向均匀分布。
本实施例中,卡块1112与保护罩111可以一体成型,可以简化保护罩111的加工步骤,提高保护罩111的生产效率。
实施例九
本实施例公开一种吹风机,与实施例八不同之处在于,如图17-图19所示,本实施例中的过滤组件112为过滤布1122,由于过滤布1122上的孔较过滤网或过滤海绵更细小,能够实现更小灰尘或者头发的过滤,较实施例八中的吹风机的过滤效果更好。
由于过滤布1122的质地较柔软,直接将过滤布1122固定在保护罩111中较难实现,且不方便过滤布1122与保护罩111的拆装,所以,本实施例的过滤组件112还包括支架1121,过滤布1122铺覆在支架1121的一面,以使过滤布1122有一定张力。将支架1121的外周卡接在保护罩111的内壁上,便能够实现过滤布1122与保护罩111的固定,方便过滤布1122与保护罩111的拆装。优选地,实施例中过滤布1122上孔的直径不超过0.3mm,可以过滤组件112保证较好过滤效果,以及较好的通风效果。此外,支架1121上开设有通风口,能够保证空气较好的通过过滤组件112。
在其他实施例中,由于较薄的过滤海绵或过滤网的质地也较柔软,较薄的过滤海绵或过滤网也能先安装在支架1121上,再将支架1121的外周卡接在保护罩111的内壁。
过滤布1122在使用一段时间需要进行更换,为了方便过滤布1122的更换,本实施例的过滤组件112还包括环状固定箍1123,过滤布1122的外周夹持在环状固定箍1123与支架1121之间,将环状固定箍1123从支架1121拆下后,便能将过滤布1122从支架1121取下进行更换。
过滤布1122铺覆在支架1121背离进风口101的一面。吹风机在使用的过程中,空气依次经过过滤布1122和支架1121,空气作用在过滤布1122上的力可以将过滤布1122抵压在支架1121上,支架1121支撑过滤布1122,可以避免过滤布1122与支架1121的分离。
过滤组件112的轴线与吹风筒100的轴线重合,支架1121包括多根关于吹风筒100的轴线对称设置的支柱,当过滤布1122抵压在支架1121时,能够使过滤布1122的受力均匀,避免过滤布1122在一些区域受力过于集中而导致的破损,提高过滤布1122的使用寿命。
本实施例中的支架1121还开设有第二避让孔,过滤罩113与过滤布1122沿吹风筒100的轴线方向位于支架1121的两侧,且至少部分过滤罩113位于第二避让孔中,能够使过滤罩113与支架1121沿吹风筒100的轴线方向的排布更紧凑,使吹风机沿吹风筒100的轴线方向的尺寸小,使吹风机的整体体积较小,便于吹风机的携带。
实施例十
本实施例提供了一种吹风机,与上述实施例的不同之处在于,如图4和图10所示,风嘴300与吹风筒100通过磁铁16吸附固定,且磁铁16隐藏设置,使得吹风机的更美观。
具体地,吹风筒100在出风口的内侧设置有磁铁16,磁铁16设置在外筒121的下游端面的内侧,风嘴300上设置有与磁铁16吸附配合的吸附块,通过磁铁16与吸附块的配合实现风嘴300与吹风筒100的固定。

实施例十一
本实施例提供了一种吹风机,与上述实施例的不同之处在于,本实施例中的风嘴300可以根据用户的需要调整出风量,不需要更换风嘴300,使用更加方便。
具体地,如图20-图27所示,风嘴包括导风件和调节件36。其中,导风件上设置有进口351、出口352以及连通进口351和出口352的风路,调节件36套设于导风件的外侧,能够相对于导风件移动,调节件36相对于导风件移动时能够调节风路上某一位置处的截面大小。
本发明中,导风件和调节件36的配合设置,能够通过一个风嘴实现出风面积的调节,使用调节简单方便,避免了设置多个风嘴的浪费,提高了风嘴的实际价值。
可选择地,导风件上设置有由软胶制成的变形区,调节件36相对于导风件移动时能够对导风件施加作用力,导风件受力后变形区发生变形,从而可以调节变形区位置处风道的截面积。在本实施例中,变形区设置于导风件上出风口102的边缘处,从而使得调节件36能够通过变形区的变形调节出风口102的大小。
具体地,导风件整体由软胶制成,受力能够发生变形,除此之外,其还可以是设置变形 区部分由软胶制成,其它部分由硬胶制成。
可选地,导风件上设置有受力块353,调节件36上设置有施力块361,调节件36相对于导风件移动时,施力块361挤压或拉伸受力块353,使得变形区变形,调节该位置处风道的截面积。
具体的,受力块353可以设置在变形区,也可以在导风件周向上靠近变形区设置。在本实施例中,导风件的出风口处节段为扁平的柱状结构,两个受力块353分别设置在该结构厚度方向两侧的平直区域,为非变形区,在该结构的周向上与非变形区相邻的弧形区域为变形区。
可选择地,受力块353为凹槽,施力块361为凸块(除此之外,还可以是受力块353为凸块,施力块361为凹槽),受力块353和施力块361至少一个的延伸方向与风道的轴线呈夹角设置,并且自出风口向内逐渐靠近风道的轴线,施力块361卡接于受力块353。其中,可以是施力块361的凸块朝向风道的轴线倾斜延伸,受力块353的凹槽可以套设于施力块361延伸方向的不同位置处,从而改变变形区位置处风道的截面积;也可以是受力块353的凹槽朝向风道的轴线倾斜延伸,施力块361的凸块可以卡装于受力块353延伸方向的不同位置处,从而改变变形区位置处风道的截面积;还可以是施力块361的凸块和受力块353的凹槽均朝向风道的轴线倾斜延伸,通过调节两者的卡接长度而改变变形区位置处风道的截面积。
在本实施例中,施力块361的凸块和受力块353的凹槽均朝向风道的轴线倾斜延伸,从而使得调节件36在导风件上,朝向出风口方向移动时,施力块361抵压受力块353朝向风道一侧的内壁,使得出风口变小,朝向进风口方向移动时,使得出风口变大(若风道不能弹性恢复,此时施力块361抵压受力块353背离风道一侧的内壁,若风道能够弹性恢复,此时施力块361逐渐放松对受力块353朝向风道一侧内壁的抵压)。整体上,通过调节件36相对于导风件的移动,调节出风口的面积。除上述设置外,自出风口向风道内部,施力块361和受力块353也可以逐渐远离风道的轴线延伸,此时,调节件36朝向出风口方向移动时,出风口变大,朝向进风口方向移动时,出风口变小。
可选择地,导风件包括相互连接的连接部37和出风部35,进风口设置于连接部37上,出风口和变形区设置于出风部35上,可调节风量的风嘴通过连接部37连接于吹风机的机体,风道贯穿连接部37和出风部35设置。
调节件36连接于连接部37,并能够相对于所述连接部37移动,并且在移动时能够对变形区施加作用力。
具体地,出风部35为扁平的柱形结构,出风部35厚度方向上相对的两侧分别设置有一个变形区,每个变形区上设置有一个受力块353,施力块361设置有两个,设置于环形的调节件36的内壁上,分别卡装于两个受力块353中。上述两个受力块353和两个施力块361设置,能够从两个方向同时对出风部35施力,提高了出风口面积的调节效率,增大了调节效果。
可选择地,调节件36通过防脱结构连接于连接部37,防脱结构用于防止调节件36从连接部37上脱离。
具体地,防脱结构包括连接卡凸362和连接卡孔371,其一个设置于调节件36上,另一个设置于连接部37上,连接卡孔371为长条形,延伸方向与风道的轴线平行,连接卡凸362能够在连接卡孔371中沿其延伸方向滑动。在本实施例中,调节件36部分套设于连接部37的外侧,调节件36内壁上设置连接卡凸362,连接部37的外壁上设置连接卡孔371,从而使得,调节件36既能够相对于连接部37移动,又不会从连接部37上脱离,并且,为了卡入安装方便,连接卡孔371朝向出风口一侧边缘的外沿处设置导向凹槽,使得在拼装时,连接卡凸362能够方便卡入连接卡孔371中。此外,除上述连接卡凸362和连接卡孔371的设置外,防脱结构还可以是连线。
可选择地,调节件36和连接部37上配合设置有导向结构,调节件36能够在导向结构的导向下沿风道的轴向滑动。
具体地,导向结构包括导向板363和导向槽372,其一个设置于调节件36上,另一个设置于连接部37上,导向板363至少部分卡入导向槽372中,导向板363和导向槽372延伸方向均与风道的轴线平行。在本实施例中,调节件36的内壁上设置导向板363,连接部37的外壁上设置导向槽372,从而保证调节件36能够相对于连接部37平稳地移动。此外,除导向板363和导向槽372外,导向结构还可以是导轨和滑块相配合的结构。
更为具体地,连接卡凸362和连接卡孔371设置有四组,导向板363和导向槽372设置有两组。连接部37相对的两侧各设置有两组连接卡凸362和连接卡孔371以及一组导向板363和导向槽372,每侧的一组导向板363和导向槽372设置于两组连接卡凸362和连接卡孔371之间。在本实施例中,连接部37朝向出风口的一侧为扁平状,其相对的两个侧面上各设置有两个连接卡孔371和一个导向槽372,每个侧面上的一个导向槽372位于两个连接卡孔371之间。
更为具体地,一个导向槽372内卡接两个导向板363,两个导向板363平行且间隔设置,两个导向板363分别抵靠于导向槽372的两个侧壁,并且导向槽372朝向出风口一端的开口处设置有外扩的导向入口,方便对位安装。
可选择地,调节件36和连接部37配合设置有档位结构,调节件36相对于连接部37移动时,调节件36能够通过档位结构保持在多个位置处,从而使得变形区位置处的风道具有多个可调节的截面积。
具体地,档位结构包括档位节块组364和档位卡凸373,档位节块组364和档位卡凸373,一个设置于调节件36上,另一个设置于连接部37上,档位节块组364包括多个档位节块,档位卡凸373能够卡入任意相邻的两个档位节块之间。在本实施例中,连接部37朝向出风口的一侧为扁平状,其相对的两个弧面上各设置有一个档位卡凸373,该档位卡凸373能够相对于连接部37弹性变形,调节件36的内壁上与两个档位卡凸373相对应的设置有两个档位节块组364,每个档位节块组364包括三个档位节块,并且三个档位节块组364可以大小一致,也可以大小不同,通过将档位卡凸373调节至不同的档位节块之间,可以将变形区位置处的风道截面积调节至不同的大小。
本发明还提供了一种吹风机,包括机体以及上述的可调节风量的风嘴,可调节风量的风嘴可拆卸地安装于机体上。
本发明的吹风机中,导风件和调节件36的配合设置,能够通过一个可调节风量的风嘴实现出风面积的调节,进而对机体的风机进行微调,使用调节简单方便,避免了设置多个风嘴的浪费,提高了风嘴的实际价值。
实施例十二
本实施例提供了一种吹风机,与上述实施例的不同之处在于,如图28和图29所示,本实施例中,风嘴300包括主体31,主体31上设置有进口和出口,其中,出口包括格栅32以及多个梳齿33,多个梳齿33由格栅32向外延伸。格栅32用于沿第一方向排出风嘴300接收的一部分空气,以形成纵向流体,其中,第一方向为风嘴300与吹风筒100连接状态时吹风筒100的轴线方向。至少部分梳齿33沿其周向开设有多个空气出口331,空气出口331用于沿第二方向(第二方向垂直于第一方向)排出另一部分空气,以形成横向流体。较每个梳齿33仅开设有一个空气出口331的方案相比,本实施例的风嘴300能提供更多路横向流体以与纵向流体发生扰动,使风嘴的出口352位置的流体更柔和,更不易向外扩散,风嘴的出口352位置的温度更高,进一步缩短烘干头发所需时间,以满足消费者的需求。
示例性地,本实施例中的梳齿33成组设置,包括第一梳齿组和第二梳齿组,第一梳齿组 包括五个呈环形阵列排布的第一梳齿,第二梳齿组包括十个呈环形阵列排布的第二梳齿,第二梳齿组的十个第二梳齿围绕第一梳齿组同轴设置。其中,每个第一梳齿的周向开设有两个沿格栅32的径向分布的第一空气出口,每个第二梳齿开设有一个第二空气出口,本实施例的风嘴300共有二十路横向气流。若每个第一梳齿仅开设有一个第一空气出口,则风嘴300共有十五路横向气流,本实施例中的风嘴300较现有技术中的风嘴能多出五路横向气流,使横向气流与纵向气流的扰动更充分。在其他实施例中,还可以设置为其他组数的梳齿组,每组梳齿组中梳齿的数量还可以设置为其它数量。
本实施例中,第二梳齿组中的第二梳齿设置在外圈,在第二梳齿上仅开设有朝向第一梳齿组的第二空气出口,能避免横向流体排出风嘴300的外周,防止带有热量的流体流失,使带有热量的流体最大限度地汇聚在格栅32的前端位置以与纵向流体扰动,以对头发进行快速烘干。
多个第一梳齿设置在内圈,若第一梳齿的数量与第二梳齿的数量相同,将会导致第一梳齿的排布过于紧密,不便于第一梳齿的后续加工。如图3所示,第一梳齿组和第二梳齿组为同心的环形阵列,在第二梳齿组中,每隔一个第二梳齿设置为朝第一梳齿组中对应的第一梳齿排出空气,以使相邻的两个第一梳齿之间的距离适当,便于第一梳齿的加工。
在格栅32与梳齿相对的一侧设置有导向风扇34,进口351、导向风扇34以及格栅32沿风嘴300的轴线依次排布,导向风扇34包括向外周导向空气的扇叶,扇叶能使从进口351进入的空气向风嘴300内侧外周扩散,使空气沿周向扩散至整个格栅32后从格栅孔中排出,保证风嘴300有较大面积的烘干区域,风嘴300单次能烘干的发量多,可有效缩短烘干头发所需时间。在其他实施例中,还可以将导向风扇34替换为能向外周导向空气的导风罩等。
为了避免用户的头发被搅入到导向风扇34中,保证用户的人身安全,将导向风扇34设置为与格栅32相对固定。螺钉沿格栅32的轴线依次旋拧于导向风扇34和格栅32上,实现导向风扇34与格栅32沿格栅32的轴线方向上固定。导向风扇34上设置有插块,格栅32上开设有插槽,插块和插槽均沿格栅32的轴线方向延伸,插块插接在插槽中,以限制导向风扇34相对于格栅32转动。通过螺钉、插块以及插槽的配合,实现导向风扇34相对于格栅32较好的固定。在其他实施例中,还可以将插块设置在格栅32上,将插槽开设在导向风扇34上,也能达到限制导向风扇34相对格栅32转动的效果。
本实施例中,插块与导向风扇34的安装盖可以一体成型,简化安装盖的加工步骤,提高安装盖的生产效率。
为了提高格栅32的开孔率(格栅孔的总面积与格栅32的面积的比值),格栅32上开设有多组同心且沿其径向间隔设置的格栅孔组,每组格栅孔组包括多个沿格栅32的周向间隔分布的格栅孔,格栅孔为弧形孔。此外,通过将格栅孔设置为弧形孔,可以使风嘴300的用料少、成本低且加工简便。
可选地,第一梳齿的内部开设有与进口351相连通的第一孔眼,第一梳齿的横截面呈椭圆形,第一空气出口为沿梳齿的长度方向切割第一梳齿形成的缺口,椭圆形的长半轴与切割面垂直。由于椭圆形的长半轴与切割面垂直,切割后的椭圆形在其长半轴方向上的尺寸减小,切割后的椭圆形的形状更趋近于圆形,使得切割后的第一梳齿的横截面趋于圆形,第一梳齿的外周较圆滑,当较圆滑的第一梳齿的周面与用户头皮接触后,用户会有非常舒适的体验感。
以上内容仅为本发明的较佳实施例,对于本领域的普通技术人员,依据本发明的思想,在具体实施方式及应用范围上均会有改变之处,本说明书内容不应理解为对本发明的限制。
