所述热风枪的功率在150W-300W之间。较佳的,热风枪100的功率为200W。
为方便与线缆200连接,所述壳体101上设有与所述电机109、所述加热组件106电性连接的第一接口103。所述第一接口103位于所述尾端105。该第一接口103可以与线缆200的一端进行可拆卸地连接(可解除地连接),进而进一步提升热风枪100的便捷性。通过设有第一接口103,使其不固定于被单一的适配器301供电,进而提升了设备使用灵活性。当然,在其他实施例中,线缆200也可以直接连接热风枪100,以不可拆卸地方式连接热风枪100。
较佳的,线缆200的一端通过插拔结构与第一接口103相电性连接,具体的,线缆200的一端具有接线端子。第一接口103可以为母端子,线缆200的一端具有与第一接口相配合的公端子。
一种可能的实施方式中,所述第一接口103为航空插座;所述线缆200的一端设有与所述航空插座相匹配的航空插头。在用户需要使用热风枪100时,将线缆200的航空插头一端直接插入热风枪100尾部的第一接口103即可实现线缆200与热风枪100的电性连接。
本实施例所提供的热风枪100通过设置适配器301向热风枪100供电,使得热风枪100自身无需设置电池等直流电源,进而可以降低热风枪100的重量,便于用户使用,而且,该热风枪100的适配器301可安装电池包302,并不采用交流电源,进而不易受到使用场景限制。而且,热风枪100的机身无需设置电池,还可以降低热风枪100尺寸,实现工具小型化。
基于同一构思,本发明实施例中还提供了一种热风枪系统,如下面的实施例所述。由于该热风枪系统解决问题的原理,以及能够取得的技术效果与热风枪相似,但不局限于上述热风枪所提供的效果以及可解决的问题,因此,该热风枪系统的实施可以参见上述热风枪的实施,重复之处不再赘述。
请参阅图1至图5,本申请另一个实施例还提供一种热风枪系统,包括:热风枪100,具有电池包安装部306的适配器301。其中,所述电池包安装部306用于可拆卸地安装电池包302。所述适配器301电性连接有线缆200;所述线缆200与所述热风枪100的第一接口103可拆卸地连接。适配器301和电池包302可以形成为热风枪100供电的外部供电组件300。 热风枪100可以采用如上任一实施例所描述的热风枪,本实施例中不再赘述。
为便于提升设备的便捷性,所述适配器301还设有第二接口305。所述第一接口103和所述第二接口305之间通过所述线缆200可拆卸地连接。如此,该热风枪系统可以可拆分地分离成独立的热风枪100、线缆200、适配器301,不仅便于收纳,而且使得热风枪100不局限于被单一适配器301供电,相应的,使得适配器301不局限向固定的热风枪100供电,进一步提升了设备的使用灵活性,以及不同场景的适应能力。
具体的,线缆200的一端通过插拔结构与第二接口305相电性连接,其中,线缆200和第二接口305的插拔结构形式可以参考线缆200与第一接口103的插拔结构形式,本申请并不作限制。当然,在其他实施例中,线缆200也可以直接连接适配器301,以不可拆卸地方式连接适配器301。
在本实施例中,所述适配器还设有用于控制所述电机109的工作参数的控制单元。具体的,控制单元可以包括:用于控制所述电机109运动的控制器、以及用于接收用户触发动作的操作部309。所述操作部309与所述控制器相连接。操作部309可以为按钮、旋钮、甚至触控屏、摇杆、开关等形式,本申请并不作唯一的限定。具体的,控制器可以为适配器301中的控制电路板。本实施例中将控制单元置于适配器301,而不是热风枪100中,可以进一步减轻热风枪100的重量以及尺寸。
具体的,所述控制单元包括用于调节所述电机的转速的手动调速模块309。该手动调速模块309可以为与控制器连接的操作旋钮。操作旋钮可以对应不同的转速档位,用户通过选取目标档位,实现不同电机转速的调节。
为便于实现对电机109的控制,传递控制信号,线缆200为多芯线缆。具体的,所述线缆200内部具有两根传输电力的导线以及一根传输控制信号的信号芯线。为便于用户实现向目标工具进行通电控制,所述适配器还设置有开关308,用于控制所述电机的开启和关闭。该开关308可以通过控制所述电池包302与第二接口之间的供电,进而控制电机的开启和关闭。为方便为其他便捷设备(例如手机、耳机)进行充电,所述适配器301还设有USB接口,进而实现一物多用,提升适配器301的使用价值。
在本实施例中,如图4、图5所示,通过电池包安装部306,电池包302可更换地安装于适配器301上,进而适配器301可以配备至少两种不同电池容量的电池包,提升热风枪100的续航能力。所述电池包302的输出电压与所述热风枪100的额定电压相同。具体的,电池包安装部可以为所述适配器301上的与所述电动工具电池(电池包)相适配的通用接口。利用通用接口,该适配器301可以安装不同电压的电池包,进而适配不同种类的电池包,提升设备的通用性。
具体的,电池包安装部306可以为适配器301上的电极座(公接头)306,电动工具电池(也可以称为电池包)上具有电极座接口(母插头)307。其中,为提升适配器301的适应能力,电极座306、以及电极座接口307可以采用通用接口。
请继续参阅图1至图4。本申请实施方式提供了一种控制装置301,用于与电动工具100配合,所述电动工具100包括电机109。所述控制装置301包括:第一壳体310;第一控制单元,收容于所述第一壳体310内,用于控制电动工具100的电机109的工作参数;电池包安装部306,其设置于所述第一壳体310上,用于连接电池包302;所述电池包302用于为所述电机109提供电力;第二接口305,与第一控制单元电性连接;当第二接口305通过线缆200与所述电动工具100连接时,所述第一控制单元与所述电机109电性连接,控制装置301能够控制电动工具100工作。
使用电动工具100时,只需要通过线缆200将控制装置301与电动工具100电性连接,即可为电机109提供电力,并控制电机109工作。此时,用户只需手持电动工具100本身即可对电动工具100进行操作,而控制装置301可以被放置在一边,用户不用承担其重量。
由以上方案可以看出,本申请实施方式所述的控制装置301通过设置第一壳体310、第一控制单元、电池包安装部306和第一接口305;使得电动工具100内不需要设置用于控制电机109的工作参数的第一控制单元;且使得电动工具100不需要设置用于连接电池包302的电池包安装部。也即将第一控制单元、电源与电动工具100分开设置。如此,一方面能减小电动工具100的体积与重量;另一方面,在利用电动工具100进行具体作业时,只需将电动工具100通过线缆200与控制装置301连接,然后将控制装置301放置在一边,用户握持电动工具100本身即可进行操作。并且,由于线缆200能发生弯曲,操作时,电动工具100与控制装置301之间的距离能发生变化,进而移动电动工具100更为方便,人机体验更佳。
本实施方式中,控制装置301能够通过线缆200与多种电动工具连接,控制其工作。
本实施方式中,第一控制单元通过控制电动工具100的电机109的工作参数来改变电机109的工作转速。该工作参数包括但不限于电机109的电压,电机109的电流,或者电机109的电压与电流的组合。对此本申请不做规定。该第一控制单元可以是包括单片机在内的电路模块。
并且,本实施方式中,控制装置301还包括与第一控制单元电性连接的手动调速钮35。该手动调速钮35供用户操纵,用于调节电机109的转速。
如图4所示,控制装置301的第一壳体310上设置有第一开关308。第一开关308用于控制电池包302向电动工具100的电力传输,从而控制电机109的开启与关闭。使用电动工具100时,用户只需触发第一壳体310上的第一开关308,电力便通过控制装置301从电池 包302流向电机109。
将用于控制电机109启停的开关28设置在控制装置301上,虽然简化了电动工具100的结构,但一定程度上也带来了操作的不便。例如在进行具体操作时,用户握持的仅仅是电动工具100本身,控制装置301通过线缆200被放置在一边;当需要改变电机109的工作状态时,用户必须前往放置控制装置301的地方对控制装置301进行操作,才能控制电机109。
为此,一种可能的实施方式中,也可仅仅在电动工具100的第二壳体101上设置第二开关。该第二开关用于控制电机109的开启和关闭。当用户握持第二壳体101时,通过该第二开关即可控制电机109的开启和关闭。该第二开关可以是薄膜开关。当然该第二开关不限于为薄膜开关,还可以是其他的开关,例如光感开关,对此本申请不做规定。
一种可能的实施方式中,也可以在第一壳体310以及第二壳体101上分别设置第一开关和第二开关。为了防止误操作,电池包302向电动工具100的电力传输只发生在第一开关先被操作,第二开关再被操作之后。此时,电机109的停止只需操作前述任意一个开关即可。
本实施方式中,控制装置301的侧边还设置有2个USB输出接口。USB输出接口输出目标电压,用于为外部电力设备,诸如手机等充电。为此,第一控制单元还包括电压转换模块,用于将电池包302的供电电压转换成目标电压。
目标电压的大小根据外部设备的需求而设定。一种可能的实施方式中,USB输出接口可以输出目标电压值为5V,电流为1A的电力。
本实施方式中,如图4、图5所示,电池包安装部306设置于第一壳体310上。具体地,电池包安装部306设置于第一壳体310的下侧,电池包安装部306与电池包302滑移配接。当电池包302连接于电池包安装部306上且控制装置301通过线缆200连接电动工具100时,该电池包302与第一控制单元和电机109形成回路;从而电池包302能够为电机109提供电力。如此控制装置301使得电池包302与电动工具100分开设置。即,控制装置301使得电池包302相对于电动工具100外置。进而相对于现有技术中的电动工具来说,本实施方式的电动工具体积更小、操作更为轻便,人机体验更佳。
请参阅图1至图5。本申请实施方式提供了一种控制装置301,用于与电动工具100配合,所述电动工具100包括电机109,所述控制装置301包括:第一壳体310;控制单元,其设置于所述第一壳体310内;用于控制电动工具100的电机109的工作参数;电池包安装部306,其设置于所述第一壳体310上;用于连接电池包302;所述电池包302用于为所述电机109提供电力;第一接口305,其通过线缆200与所述电动工具100连接,使得所述控制单元与所述电机109电性连接。
使用电动工具100时,只需要将控制装置301上的线缆200与电动工具100上的第二接 口103电性连接,即可使得控制单元与电机109电性连接,从而控制单元能控制电机109的工作参数。此时,用户只需手持电动工具100本身即可对电动工具100进行操作,而控制装置301可以被放置在一边,用户不用承担其重量。
由以上方案可以看出,本申请实施方式所述的控制装置301通过设置第一壳体310、控制单元、电池包安装部306和第一接口305;使得电动工具100内不需要设置用于控制电机109的工作参数的控制单元;且使得电动工具100内不需要设置用于为电机109提供电力的电源。也即将控制单元、电源与电动工具100分开设置。如此能减小电动工具100的体积。另一方面操作时只需要将线缆200的另一端与电动工具100的电机109电性连接,即可手持第二壳体101对电动工具100进行操作,由于线缆200能发生弯曲,所以操作时电动工具100与控制装置301之间的距离能发生变化,进而方便移动电动工具100;人机体验更佳。另一方面,本申请实施方式所述的控制装置301能用于多种电动工具100中,如此实现对本申请实施方式所述的控制装置301的重复利用,不仅可以提升本申请实施方式所述的控制装置301的适配性,还可以降低电动工具系统的生产成本。
本申请实施方式所述的电动工具100采用无刷电机109,其具有比有刷电机更高的能量密度,也即,在保证电机工作能力的情况下,电机的结构尺寸可以做小,进而筒状壳体的外径尺寸可以做小。本实施方式中,无刷电机的功率在150W-300W之间,电机的额定功率与筒状壳体的外径的比值不小于3W/mm,由此获得了一种工作能力强,且符合人体工程学的设计。
在本实施方式中,如图3所示,电动工具100包括第二壳体101、设置于第二壳体101内的电机109以及设置于第二壳体101上的第二接口103。具体地,该第二壳体101为中空结构。该中空部分形成第一容置空腔。该电机109收容于该第一容置空腔内。进而能通过该第二壳体101对电机109进行保护,提升安全性。进一步地,该第二接口103与电机109电性连接。从而当第二接口103与线缆200电性连接时,该电机109能通过线缆200与控制单元电性连接。进一步地,该电机109为无刷电机。因此,本申请实施方式中的电动工具100效率更高。
在本实施方式中,如图1所示,该控制装置301包括第一壳体310、设置于所述第一壳体310内的控制单元、设置于所述第一壳体310上的电池包安装部306以及与第一接口305。具体地,该第一壳体310为中空结构。该中空部分形成第二容置空腔。该控制单元收容于该第二容置空腔内。进而能通过该第二壳体101对控制单元进行保护。另一方面,当需要对控制单元进行升级和维修时,可以通过打开该第一壳体310对该控制单元进行维修和升级,如此方便了操作。
在本实施方式中,所述控制单元用于控制所述电机109的工作参数。该工作参数可以是 电机109的转速。当然该工作参数不限于为电机109运转的速度,还可以是电机109的电压,电机109的电流,或者电机109的电压与电流的组合。本实施方式的控制装置,通过改变供应给电机109的电压或者电流,并最终使得电机109的转速改变。对此本申请不做规定。该控制单元可以是传感器、单片机等组成的电路模块。
具体地,该控制单元包括手动调速模块309。该手动调速模块309用于调节电机109的转速。
进一步地,该控制单元还可以包括温度检测模块和过载保护模块。具体地,该温度检测模块用于检测控制单元的工作温度。该过载保护模块用于在当该控制单元的工作电流超过预设值时,切断电源或者切换电机109的工作模式。
在本实施方式中,第一接口305通过线缆200与电动工具100连接,使得控制单元与电机109电性连接。例如如图1所示,线缆200的左端与第一接口305电性连接。线缆200的右端与电动工具100的第二接口103电性连接。从而通过该线缆200一方面能将控制单元与电机109电性连接。另一方面通过该线缆200还能使得控制装置301与电动工具100分开设置,如此操作时只需要通过线缆200将控制装置301的第一接口305与电动工具100的第二接口103电性连接,即可手持第二壳体101对电动工具100进行操作。由于线缆200能发生弯曲,所以操作时,电动工具100与控制装置301之间的距离能发生变化,进而方便移动电动工具100,人机体验更佳。具体地,该线缆200例如可以是铜线。当然该线缆200不限于为铜线,还可以是其他的金属线,例如铝线等,对此本申请不做规定。
在本实施方式中,电池包安装部306设置于第一壳体310上。例如如图1所示,电池包安装部306设置于第一壳体310的下侧。该电池包安装部306用于连接电池包302。且该电池包302用于为电机109提供电力。本实施方式中,电池包302与电池包安装部滑移配接。具体地,当电池包302连接于电池包安装部306上时,该电池包302与控制单元和电机109形成回路。从而电池包302能够为电机109提供电力。如此控制装置301使得电池包302与电动工具100分开设置。也即使得电池包302相对于电动工具100外置。进而相对于现有技术中的电动工具100来说,体积更小、操作更为轻便,携带更为方便,人机体验更佳。
进一步地,控制单元与电池包安装部306或电源插接部电性连接,以使电池包302或外部电源能为控制单元提供电力。具体地,当电池包302电性连接于电池包安装部306上时,该电池包302与控制单元和电机109形成回路。而当外部电源电性连接于电源插接部25上时,该外部电源与控制单元和电机109形成回路,从而外部电源能够为电机109提供电力。进一步地,该控制单元可以通过控制电路选择电池包安装部306和电源插接部中的一个进行电性连接,以避免控制单元同时与电池包安装部306和电源插接部相连。
进一步地,控制单元与电源插接部电性连接时,控制单元还用于对外部电源进行变压,以控制外部电源分配给电机109上的电压。具体地,该控制单元还包括整流模块。该整流模块用于对外部电源进行变压。例如该整流模块用于将外部电源输出的电压转换为预设电压范围内的直流电压,并将直流电压输出给控制单元。由于电机109的工作电压通常情况下为直流电压,而当外部电源为交流电时,即可通过该整流模块可以将外部电源的交流电转换为直流电,以供电机109使用。例如当外部电源为220伏,50赫兹的交流电压时,通过该整流模块,可以将220伏,50赫兹的交流电压转换成如250伏的直流电压。
在一个实施方式中,如图4、图5所示,本申请实施方式的控制装置301还包括:用于连接在电池包安装部306上的电池包302;或者用于连接在电源插接口上的外部电源;电池包302和外部电源均用于为电机109提供电力。该外部电源可以为背负式电源。例如该外部电源为背包式电源或者腰包式电源。当然该外部电源不限于为背负式电源,还可以是其他的电源,对此本申请不做规定。
由以上方案可以看出,本申请实施方式所述的电动工具系统通过设置第一壳体310、控制单元、电池包安装部306和第一接口305;使得电动工具100内不需要设置用于控制电机109的工作参数的控制单元;且使得电动工具100内不需要设置用于为电机109提供电力的电源。也即将控制单元、电源与电动工具100分开设置。如此能减小电动工具100的体积和重量。另一方面手持第二壳体101对电动工具100进行操作,由于线缆200能发生弯曲,所以操作时电动工具100与控制装置301之间的距离能发生变化,从而方便移动电动工具100,人机体验更佳。另一方面,本申请实施方式所述的电动工具系统中的控制装置301用于多种电动工具100中,这样,不仅可以提升控制装置301的适配性,还可以降低电动工具100的生产成本。又因为本申请实施方式所述的电动工具系统中的电动工具100采用无刷电机109,因此,效率更高。
在一个实施方式中,如图4、图5所示,本申请实施方式的电动工具系统还包括:开关308。该开关308用于控制电机109的开启和关闭。具体地,该开关308可以设置于第二壳体101上。从而可以在握持第二壳体101时,通过该开关308控制电机109的开启和关闭。当然该开关308不限于设置于第二壳体101上,还可以是设置于第一壳体310上。从而可以在握持第一壳体310时,通过该开关308控制电机109的开启和关闭。进一步地,该开关308还可以包括设置于第一壳体310上的第一开关和设置于第二壳体101上的第二开关。该第一开关能与第二开关电连接,且第二开关只有在第一开关处于开启状态时才能被打开;如此能避免误打开电动工具所引发的安全事故,进而提高电动工具100使用的安全性。该开关308可以是薄膜开关308。当然该开关308不限于为薄膜开关308,还可以是其他的开关308,例 如光感开关308,对此本申请不做规定。
本文引用的任何数字值都包括从下限值到上限值之间以一个单位递增的下值和上值的所有值,在任何下值和任何更高值之间存在至少两个单位的间隔即可。举例来说,如果阐述了一个部件的数量或过程变量(例如温度、压力、时间等)的值是从1到90,优选从20到80,更优选从30到70,则目的是为了说明该说明书中也明确地列举了诸如15到85、22到68、43到51、30到32等值。对于小于1的值,适当地认为一个单位是0.0001、0.001、0.01、0.1。这些仅仅是想要明确表达的示例,可以认为在最低值和最高值之间列举的数值的所有可能组合都是以类似方式在该说明书明确地阐述了的。
除非另有说明,所有范围都包括端点以及端点之间的所有数字。与范围一起使用的“大约”或“近似”适合于该范围的两个端点。因而,“大约20到30”旨在覆盖“大约20到大约30”,至少包括指明的端点。
应该理解,以上描述是为了进行图示说明而不是为了进行限制。通过阅读上述描述,在所提供的示例之外的许多实施方式和许多应用对本领域技术人员来说都将是显而易见的。因此,本教导的范围不应该参照上述描述来确定,而是应该参照所附权利要求以及这些权利要求所拥有的等价物的全部范围来确定。出于全面之目的,所有文章和参考包括专利申请和公告的公开都通过参考结合在本文中。在前述权利要求中省略这里公开的主题的任何方面并不是为了放弃该主体内容,也不应该认为发明人没有将该主题考虑为所公开的实用新型主题的一部分。
