具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解,现对照附图详细说明本发明的具体实施方式。
如图 1 和图 2 所示,本发明 第一 实施例提供的电子水烟,包括控制模块 2 、通气盖 4 、用于雾化烟油的雾化器 3 、底座 1 和插接头 8 。其中,控制模块 2 和插接头 8 分设在底座 1 的两侧,且底座 1 与控制模块 2 可拆卸地连接,雾化器 3 位于所述底座 1 内,通气盖 4 的一端固定在控制模块 2 靠近底座 1 的一侧,且通气盖 4 收容在所述底座 1 内并位于控制模块 2 和雾化器 3 之间。插接头 8 插设在底座 1 远离控制模块 2 的一侧,并用于连接吸气管或水烟壶,供用户吸食使用。
底座 1 上设有第一进气孔 11 , 插接头 8 上设有供气流 流出的 出气孔 81 ,在通气盖 4 内还形成有与第一进气孔 11 和出气孔 81 相通的通气道(未标出),该通气道与第一进气孔 81 、出气孔 81 相连通形成电子水烟内的气流流通通道,使外界大气从第一进气孔 11 进入电子水烟,然后流经通气道和出气孔 81 将雾化器 3 雾化烟油产生的烟雾带出供用户吸食。本实施例中, 第一进气孔 11 设置在底座 1 远离控制模块 2 的一侧 , 且 当用户从出气孔 81 处吸食电子水烟时,外界大气从电子水烟下端 的第一进气孔 11 处流入,在电子水烟内部流经一个回路后又携带烟雾从插接头 8 上的出气孔 81 流出,依次循环供用户在出气孔 81 处抽吸该电子水烟。优选地,第一进气孔 11 为两个,且该两个第一进气孔 11 分设在出气孔 81 的两侧,以使外界大气从两个第一进气孔 11 流入,从而在电子水烟内形成两个外界大气流入通道,使电子水烟内部气流流通顺畅。
底座 1 大体为一个中空的梯形支架,其用于收容雾化器 3 和通气盖 4 。具体地,雾化器 3 和通气盖 4 均收容在底座 1 内,雾化器 3 和通气盖 4 的端面抵持固定,且雾化器 3 和通气盖 4 与底座 1 的侧壁之间设有间隙,以使从第一进气孔 11 流入的气流在该间隙内向上流动,并能进入通气盖 4 内。
控制模块 2 包括外壳 22 、 PCB 电路板 21 和电池 23 ,其中 PCB 电路板 21 和电池 23 均设置在所述外壳 22 内,且外壳 22 的一端延伸至底座 1 内,通气盖 4 收容在延伸至底座 1 内的外壳 22 内,且该延伸至底座 1 内的外壳 22 的端部与雾化器 3 的一端部抵持。外壳 22 上 远离底座 1 的一侧 设有与外界大气相通的第二进气孔 223 ,且外壳 22 上还设有 用于为电池 23 充电的充电接口(未示出),第二进气孔 223 用于使外界大气流入壳体 22 内,并流向压差传感器 6 的一侧。充电接口给电池 23 充电,以使电池 23 重复使用。由于 PCB 电路板 21 设置在控制模块 2 上,且气流流通通道不经过控制模块 2 ,因此雾化器 3 雾化的烟油不会流入控制模块 2 内,避免烟油流至 PCB 电路板 21 上,可有效地保护 PCB 电路板 21 。
通气盖 4 上 设有压差感应器 6 和 位于通气道上的 用于保护压差感应器 6 的单向阀 5 ,且压差感应器 6 与 PCB 电路板 21 电连接。其中,压差感应器 6 的一侧与 通气道 相 连 通,压差感应器 6 的另一侧与外界大气相通,具体地压差感应器 6 的另一侧经所述第二进气孔 223 与外界大气相通 ,即压差感应器 6 用于检测通气道内的气流与外界大气之间的压力差,也即压差感应器 6 用于测量通气盖 4 两侧的压力差 。用户通过出气孔 81 吸食电子水烟时,单向阀 5 沿着通气道内的 气流流通的方向被打开,且压差感应器 6 检测到 通气道内的气流与外界大气存在压力差 时,压差感应器 6 将该压差信号发送至控制模块 2 ,所述控制模块 2 控制雾化器 3 雾化烟油产生烟雾。而当在异常情况下,用户不小心从出气孔 81 向电子水烟内吹气时,单向阀 5 在相反的气流流通方向下闭合上,即通气盖 4 内的通气道被关闭从而阻断气流流通通道,从而避免反吹的气压太大而将压差感应器 6 吹坏或损坏其它器件,即单向阀起到保护压差感应器 6 的作用。
如图 3 、图 4 和图 5 所示, 通气盖 4 上设有一轴向贯通的通孔 46 ,且该通孔 46 与通气道相连通,压差感应器 6 嵌设在通孔 46 内从而使通气道和第二进气孔 223 相隔离。即通过将压差感应器 6 嵌设在通孔 46 内,使通气道内的气流不能通过通孔 46 流向另一侧的第二进气孔 223 处,从而使经第二进气孔 223 流入电子水烟内的外界大气与通气道内的气流相隔离。在其它实施方式中,压差感应器 6 并不限于嵌设在通孔 46 内,也可抵持在通孔 46 的一端面上,只要满足使经第二进气孔 223 流入的外界大气与通气道内的气流隔离即可。
通气盖 4 大体为帽状,包括帽盖 41 和圆筒 42 。圆筒 42 为中空的筒状,缩径设置在帽盖 41 内;且圆筒 42 的侧壁与帽盖 41 的侧壁间隔设置,即在圆筒 42 和帽盖 41 的侧壁之间设有间隙,该间隙用于使气流在通气盖 4 内流通。
盖帽 41 的侧壁上设有供气体流入的第一缺口 411 ,圆筒 42 上与第一缺口 411 相对的侧壁上设有轴向贯穿的第二缺口 421 ,且第一缺口 411 的周向距离大于第二缺口 421 的周向距离。即盖帽 41 的侧壁是半圆形的,从而在盖帽 41 上形成半圆形的第一缺口 411 ,第二缺口 421 的位置大体与第一缺口 411 的中部相对应,从而形成周向距离小于第一缺口 411 的第二缺口 421 。且第二缺口 421 的一侧与第一缺口 411 之间设有阻挡气体流通的第一挡板 43 ,第二缺口 421 的另一侧设有与盖帽 41 的侧壁连接的第二挡板 44 ,即第一挡板 43 和第二挡板 44 横向设置在盖帽 41 和圆筒 42 之间,并用于阻挡气体任意流通。第一挡板 43 的一端固定在圆筒 42 靠近第二缺口 421 的侧壁上,另一端固定在第一缺口 411 的中部,从而将第一缺口 411 分成隔离的两部分。第二挡板 44 的一端固定在圆筒 42 上,另一端固定在帽盖 41 的侧壁上,且第二挡板 44 和第一挡板 43 分别位于第二缺口 421 的两侧。第二挡板 44 上设有收容孔 441 ,单向阀 5 收容在该收容孔 441 内,收容孔 441 大体呈 ' 门 ' 形,单向阀 5 的一端固定在收容孔 441 的底部,另一端可向第一缺口 411 的一侧打开(单向阀的打开方向如图 3 中的箭头方向所示),以实现单向流通气流的作用。
如图 5 所示,单向阀 5 包括底板 51 及垂直固定在底板 51 上的薄片 52 ,薄片 52 远离底板 51 的一端可顺着气流流通方向打开从而使薄片 52 两侧的气流流通。其中薄片 52 由硅胶材料制成,当气流从第一缺口 411 流入通气盖 4 内后,沿着盖帽 41 和圆筒 42 的侧壁之间的间隙流通至单向阀 5 处时,在气流的作用下薄片 52 向第一缺口 411 一侧打开,从而使气流流入第二缺口 421 处,并继续流向圆筒 42 中空的内部。本实施例中, 通孔 46 开设在盖帽 41 上靠近 单向阀 5 的一侧,并位于单向阀 5 远离第一挡板 43 的一侧, 即 压差感应器 6 位于靠近单向阀 5 的一侧 ,并设置在与单向阀 5 的打开方向相反的一侧,以提高压差感应器 6 的灵敏度。
第一缺口 411 、收容孔 441 和第二缺口 421 相通形成通气盖 4 内的通气道。如图 6 所示,箭头方向表示气流流通方向,即气流从第一缺口 411 流入,由于第一挡板 43 的阻挡作用,气流只能沿着一个方向流动,并沿着帽盖 41 和圆筒 42 之间的间隙流至单向阀 5 处时,单向阀 5 打开以使气流经第二缺口 421 流入中空的圆筒 42 内,在通气盖 4 内形成大致呈 ' G ' 形的通气道。
如图 2 所示,外壳 22 的侧壁上设有相互隔离的第一通气孔 221 和第二通气孔 222 ,且第一通气孔 221 和第二通气孔 222 均设置在第一挡板 43 远离第二挡板 44 的一侧的外壳 22 的侧壁上。即第一通气孔 221 和第二通气孔 222 均与第一挡板 43 远离第二挡板 44 的一侧的第一缺口 411 相对,以使气流只能通过沿着一个方向流动而不能逆流,即由于第一挡板 43 的阻挡作用,从第一通气孔 221 和第二通气孔 222 流入的气体只能从与其对应的第一缺口 411 的一侧流入,然后沿通气道向一个方向流动。其中,第一通气孔 221 和第二通气孔 222 均与第一进气孔 11 相通,以使外界大气经第一进气孔 11 流入电子水烟内后,接着流经第一通气孔 221 和第二通气孔 222 流入盖帽 41 内,然后沿盖帽 41 的侧壁与圆筒 42 的侧壁之间的间隙流至单向阀 5 时,所述单向阀 5 在气流流通的作用下单向打开,此时压差感应器 6 检测到通气盖 4 两侧存在压力差,导通电路使雾化器 3 开始雾化烟油产生烟雾,则经单向阀 5 流入圆筒 42 内的气流继续流向雾化器 3 处,并将雾化器 3 雾化烟油产生的烟雾从出气孔 81 带出,供用户吸食。
通气盖 4 上还设有至少一个透气孔 45 ,该透气孔 45 设置在盖帽 41 的侧壁和圆筒 42 的侧壁之间的间隙内,并靠近第二挡板 44 的一侧,具体地透气孔 45 位于所述通气道内, 与压差感应器 6 对应设置并与 通孔 46 相通,以使通气道内流通的气体能通过透气孔 45 并能被压差感应器 6 感应到,即压差感应器 6 通过该透气孔 45 感应气流流通通道内的 气流 压力。
具体地,压差感应器 6 嵌设在通气盖 4 内,且压差感应器 6 的一侧通过透气孔 45 与通气盖 45 内的通气道相通,压差感应器 6 的另一侧与经第二进气孔 223 流入的外界大气相通,即该压差传感器 6 用于检测经第二进气孔 223 流入壳体 22 内的外界大气与通气道内流通的气体之间的压力差,当检测到存在压力差时,电热丝 322 通过 PCB 电路板 21 自动与电池 23 导通,以雾化烟油产生烟雾。可以理解,压差感应器 6 两侧的气流互不流通,即通气道内的气流与从第二进气孔 223 流入的空气之间互不流通。
透气孔 45 的轴向端面与使第一通气孔 221 和第二通气孔 222 间隔的外壳 22 的侧壁相对应,即透气孔 45 的轴向端面高度大于第一通气孔 221 的高度而小于第二通气孔 222 的高度,以使透气孔 45 的端面与间隔在第一通气孔 221 和第二通气孔 222 之间的外壳 22 的侧壁相对应。则当不小心将电子水烟倒放时,烟油会从雾化器 3 内回流至通气盖 4 的通气道内,由于透气孔 45 的轴向端面高度大于第一通气孔 221 的高度,则烟油会从第一通气孔 221 流出,避免烟油流至压差感应器 6 上;当将倒放的电子水烟重新正放时,通气道内残留的烟油又会从第二通气孔 222 流出,同样可避免烟油通过透气孔 45 流至压差感应器 6 上,防止烟油损坏压差感应器 6 ,提高其使用寿命。可以理解,透气孔 45 的个数不受限制,可以为更多个,且使透气孔 45 的孔径尽可能小,只要满足压差感应器 6 能感应到通气道内的气流即可,以防止烟油经透气孔 45 流入压差感应器 6 上。优选地,在通气盖 4 内设有两个独立工作的压差感应器 6 ,即使其中一个坏了,另一个仍能正常工作,提高电子水烟的使用寿命。
雾化器 3 包括用于存储烟油的储油器 31 和用于雾化烟油的电热丝组件 32 ,电热丝组件 32 包括插设在储油器 31 内并用于吸附烟油的导油绳 321 及用于雾化烟油的发热丝,且发热丝 322 的两端与 PCB 电路板 21 电连接,当压差感应器 6 检测到通气盖 4 两侧存在压力差时,发热丝 322 通过 PCB 电路板 21 自动与电池 23 导通,以雾化烟油产生烟雾。在储油器 31 内还形成有与通气道相通的气道(未示出),以使气流流经通气道后,通过流经储油器 31 内的气道从出气孔 81 流出。
如图 7 所示,本实施例的电子水烟直接连接吸气管 7 上进行抽吸,具体地吸气管 7 插设在出气孔 81 内,则用户直接吸食吸气管 7 ,在电子水烟内部形成负压,外界大气分别通过第一进气孔 81 和第二进气孔 223 流入电子水烟内,当从第一进气孔 81 进去的气体流入通气道内并使单向阀 5 打开时,压差感应器 6 感应到通气道与从第二进气孔 223 流入的气体之间的压力差,则导通电路使雾化器雾化烟油产生烟雾并从出气孔 81 流出至用户口腔中,供用户吸食。
如图 8 所示,本实施例的电子水烟先套设在水烟壶 9 上,然后再将吸气管 7 插设在水烟壶 9 上进行抽吸,具体的工作原理与上述实施例相同,不在赘述。
本 实施例 的电子水烟,在控制模块 2 和雾化器 3 之间设置了一通气盖 4 ,并在通气盖 4 内形成有与第一进气孔 11 和出气孔 81 相通的通气道从而形成气流流通通道,并通过在通气盖 4 内设置压差感应器 6 和单向阀 5 ,且压差感应器 6 的一侧与气流流通通道相通,另一侧与外界大气相通 。则当用户吸食电子水烟时,单向阀 5 沿 着气流流通通道的方向被打开,压差感应器 6 检测到所述通气盖 4 两侧存在压力差时,所述雾化器 3 才雾化烟油产生烟雾;而当在异常情况下,用户不小心从出气孔 81 向电子水烟内吹气时,单向阀 5 在相反的气流流通方向下被推合上,即通气盖 4 内的通气道被关闭,从而避免反吹的气压太大而将压差感应器 6 吹坏或损坏其它器件。
如图 9 所示,本发明第二实施例提供的通气盖 4 ,其与第一实施例的不同之处在于:在 第二挡板 44 远离第一挡板 43 的一侧设有 密封板 47 ,该密封板 47 固定在 盖帽 41 的侧壁与圆筒 42 的侧壁 之间,且通孔 46 和透气孔 45 设置在密封板 47 和第二挡板 44 之间形成的密闭空间内。即本实施例中,压差感应器 6 和透气孔 45 设置在密封板 47 和第二挡板 44 之间的密闭空间内,且只有当单向阀 5 打开时,压差感应器 6 才能感应到从第二进气孔 223 流入壳体 22 内的外界大气与通气道内流通的气体之间的压力差。而当用户不小心从出气孔 81 向电子水烟内吹气时,此时单向阀 5 处于关闭状态,则反吹的气压不会进而密闭空间内,避免了压差感应器 6 损坏的现象,提高了压差感应器 6 的使用寿命。
圆筒 42 的侧壁上还设有与 第一缺口 411 相通的第三缺口 422 ,且第三缺口 422 位于密封板 47 远离第二挡板 44 的一侧。则当用户吸食电子水烟时,单向阀 5 被打开,气流从第一缺口 411 流入通气盖 4 内,并沿着盖帽 41 和圆筒 42 的侧壁之间的间隙流至第三缺口 422 处,然后经第三缺口 422 流入圆筒 42 中空的内部,并流向雾化器 3 。由于单向阀 5 被打开,密封板 47 和第二挡板 44 之间的密闭空间内的气压减小,则压差感应器 6 检测到其两侧的压力差, 导通电路使雾化器 3 开始雾化烟油产生烟雾, 最后经 圆筒 42 流 向 雾化器 3 处 的气流 ,将雾化器 3 雾化烟油产生的烟雾从出气孔 81 带出,供用户吸食。
如图 10 所示, 当 用户 不小心将电子水烟倒放时, 雾化器 3 的储油器 31 内残留的烟油会回流至通气盖 4 内, 由于透气孔 45 的轴向端面高度大于第一通气孔 221 的高度, 且单向阀 5 处于闭合状态,则烟油会从第三缺口 422 经第一缺口 411 从通气盖 4 内流出, 避免烟油流至压差感应器 6 上 ,提高了压差感应器 6 的使用寿命。
进一步地, 使用本实施例二提供的电子 水 烟,同样能实现如实施例一中电子 水 烟的有益效果 ,在此不再赘述 。
本发明还提供了一种电子水烟的雾化控制方法,包括以下步骤:
S1 :接收到吸烟信号后,单向阀 5 沿 着 通气道内气流流通 的方向被打开;
S2 :压差感应器 6 检测到 通气道的气流与外界大气存在压力差时 ,所述压差感应器 6 将该压差信号发送至控制模块 2 ;
S3 :所述控制模块 2 控制雾化器 3 雾化烟油产生烟雾。
其中,电子水烟包括 控制模块 2 、通气盖 4 、用于雾化烟油的雾化器 3 、底座 1 和插接头 8 ,在通气盖 4 内设有压差感应器 6 和单向阀,且在通气盖 4 内还形成有通气道,具体的电子水烟的连接结构在上述实施例中已经详述过,在此不再赘述。
本发明的电子水烟的雾化控制方法,外界大气 一直可 从第一进气孔 11 流入电子水烟内部 ,而当 用户从出气孔 81 处吸食电子 水 烟,使电子水烟接收到吸烟信号,气流 从第一进气孔 11 流至通气盖 4 内的通气道内,单向阀 5 沿 着气流流通的方向被打开,此时压差感应器 6 检测到气流流通通道内的气流压力与经第二进气孔 223 流入的外界大气之间的压力差,即压差感应器 6 检测到通气盖 4 两侧存在的压力差,压差感应器 6 将该压差信号发送至控制模块 2 ,所述控制模块 2 控制雾化器 3 雾化烟油产生烟雾,产生的烟雾经出气孔 81 流出供用户吸食。而当用户不小心从出气孔 81 处向电子水烟内吹气时,由于单向阀只能向一个方向打开,则单向阀 5 闭合从而阻断气流流通通道,使气流不能流向压差感应器 6 的一侧,从而避免反吹的气压太大时损坏压差感应器 6 或其它部件,延长了电子水烟的使用寿命。且该雾化控制方法操作简单,有助于提高用户体验。
上面结合附图对本发明的实施例进行了描述,但是本发明并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本发明的启示下,在不脱离本发明宗旨和权利要求所保护的范围情况下,还可做出很多形式,这些均属于本发明的保 护之内。
