Description

一种具有触碰式开关的便携式雾化器 技术领域
本发明涉及医疗器械领域，特别涉及一种具有触碰式开关的便携式雾化器。
背景技术
雾化吸入治疗是呼吸系统疾病治疗方法中一种重要和有效的治疗方法，采用雾化器将药液雾化成微小颗粒，使用者通过呼吸将药物吸入呼吸道和肺部沉积，经其粘膜吸收，从而达到无痛、迅速、有效治疗的目的。目前，雾化器发展趋势已经从较笨重的压缩型雾化器发展到手持式的便携式雾化器，这无疑对雾化器轻量化和其结构的简单化等方面提出了更高的要求。然而，现有便携式雾化器仍然存在缺陷。传统的机械式按键结构复杂，由于键程的设置不可避免的会增加机身厚度和重量，造成雾化器不够轻便；并且在长时间使用过程中会出现机械磨损，使用寿命短等问题。
发明内容
为解决上述技术问题，本发明提出了一种具有触碰式开关的便携式雾化器,可以简化机身结构，具有重量轻、体积小和开关使用寿命长的特点。
为此，本发明采用如下技术方案：
一种具有触碰式开关的便携式雾化器,包括壳体、在壳体一侧设有的喷嘴、在喷嘴一侧的壳体内设有的雾化片和在雾化片一侧设有的药液箱，及在壳体内设有与雾化片连接的电路板和与电路板连接的电池；所述电路板包括依次相连接的主控单元、雾化驱动单元和升压单元；所述升压单元与电池相连接，所述雾化片与雾化驱动单元相连接；所述壳体至少部分采用绝缘材料制 成，所述雾化器还包括触摸感应件和电容式触摸IC，所述触摸感应件紧贴在绝缘壳体内侧，所述电容式触摸IC的输入端与触摸感应件相连接，电容式触摸IC的输出端与主控单元的按键检测接口相连接。
进一步的，所述触摸感应件为金属铜箔。
进一步的，所述触摸感应件通过固定夹具和双面胶紧贴在所述壳体内侧。
进一步的，所述主控单元为单片机MCU。
进一步的，所述雾化器还包括与主控单元相连接的指示单元。
本发明的有益效果是：在使用时人体通过触摸触摸感应件所在上方的绝缘壳体，感应电容发生变化，电容式触摸IC会将变化的电信号以高电平的方式输送到主控单元的按键检测接口，从而使雾化器进入待机状态。在人体离开触摸感应件所在上方的绝缘壳体后，感应电容同样发生变化，此时电容式触摸IC会将变化的电信号以低电平的方式输送到主控单元的按键检测接口，从而使雾化器关闭。本发明通过在壳体内侧设置一个紧贴的触摸感应件，节省了雾化器内部空间并减轻了重量；由于没有设置机械结构，减少了机械损耗，延长了开关使用寿命。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图1、图2所示是本实施例的一种具有触碰开关的便携式雾化器的立体图和剖面图，包括壳体1、在壳体1一侧设有的喷嘴2、在喷嘴2一侧的壳体内设有的雾化片3和在雾化片3一侧设有的药液箱4，及在壳体1内设有与雾化片3连接的电路板5和与电路板5连接的电池6。壳体1的手持区域应至少部分采用绝缘材料制成，用来做电容式触摸开关的接触面板，其材料可以是玻璃、聚苯乙烯、聚氯乙烯、树脂玻璃、硬尼龙等。如图3所示，在绝缘壳体内侧还设有触摸感应件7，触摸感应件应紧密贴在绝缘壳体内侧，以防止电容的介电常数变小从而降低触摸感应的灵敏度。在本实施例中，触摸感应件7是通过壳体内侧设有的固定夹具8和双面胶与壳体紧紧贴合在一起的。触摸感应件7必须是导电体，可以是印制PCB的金属铜箔或其他金属材料。在本实施例中，触摸感应件采用的是金属铜箔。
如图4所示是本实施例的电路部分的结构框图，电路板包括依次相连接的主控单元、雾化驱动单元和升压单元；雾化驱动单元与雾化片相连接；升压单元与电池相连接；主控单元用于整个电路部分的逻辑控制部分，负责接收外部输入信息并控制驱动频率和驱动电压；升压单元用于输出加载在雾化片驱动单元两端的电压；雾化驱动电路用于根据驱动频率和驱动电压以驱动雾化片。在本实施例中，主控单元采用的是低功耗、自带存储空间、支持多协议的单片机MCU。电路部分还包括电容式触摸IC，电容式触摸IC的输入端与触摸感应件相连接，电容式触摸IC的输出端与主控单元的按键检测接口相连接。具体如图5所示，其中U10为一个2通道电容式触摸感应IC，PG代表触摸感应件，引脚6为输入端，引脚8为输出端，KEY_TOUCH连接MCU的按键检测接口；电容C1起到滤波作用；电容C13起到调节感应灵敏度的作用。在本实 施例中，电容C13的容值是104即0.1微法，是触摸感应最灵敏的状态。当使用者的手接触到触摸感应件PG时，感应电容发生变化，触摸IC会在KEY_TOUCH输出一个高电平，通知主控单元触摸事件的发生，从而控制雾化器进入待机状态；当手离开触摸感应件PG时，触摸IC会在KEY_TOUCH输出一个低电平，通知主控单元触摸事件的结束，从而控制雾化器关闭。在一些变形实施例中，雾化器还包括提示雾化器进入待机状态的指示单元，指示单元与主控单元相连接。指示单元可以采用以下一种或几种形式组合包括声音、灯光和振动。
以上内容是结合具体/优选的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，其还可以对这些已描述的实施方式做出若干替代或变型，而这些替代或变型方式都应当视为属于本发明的保护范围。
