Description

双进气高效气泵
技术领域
本发明涉及一种气泵，具体为双进气高效气泵。 
背景技术
随着工业技术的发展和人们生活水平的提高，各种车辆用轮胎和充气产品越来越多，因此各种充气泵也应运而生。目前，现有技术中所述的传统气泵一般包含壳体、电机、偏心轮、支座、气囊组、阀座、单向进气阀、顶盖和单向出气阀；电机安装在壳体中，壳体上开有供气孔；偏心轮安装在电机的传动轴上；支座架在壳体上，支座上形成贯通的进气孔；气囊组借助阀座固定支撑在支座上，气囊组的底部借助传动杆固定在偏心轮上，由电机和偏心轮带动做交替式打气，气囊组的边缘对应进气孔形成单向进气阀；阀座上对应气囊组的气囊位置形成贯通的出气孔，阀座的底面对应气囊组的单向进气阀和气囊形成输气槽；单向进气阀和单向出气阀分别盖在进气孔和出气孔上；顶盖固定盖在阀座上，顶盖对应阀座的出气孔形成出气腔，且顶盖上还形成与出气腔连通的出气管。使用时，气体直接由壳体上的供气孔进入壳体内，经支座的进气口上行，将气囊组上的单向进气阀冲开，经阀座的输气槽进入气囊中；电机驱动传动杆摆动，使气囊压缩或扩张，将气体经阀座的出气孔上行，将单向出气阀冲开，进入顶盖的出气腔，经出气管出去实现气泵功能。但这种使用偏心凸轮的驱动结构势必会造成气泵内元件的不平衡，从而造成较大的振动，当电机运行于一个较高的转速时，这种振动尤其明显，并且伴随着振动产生了较大的噪音和电子干扰，对周围环境造成噪音污染，也会降低气泵的使用寿命，而且工作效率较低。 
发明内容
为克服上述缺陷，本发明提供一种噪音小、双进气、工作效率高的新型气泵，彻底改变了原来偏心凸轮驱动的的工作结构和原理。 
为实现上述目的，本发明的技术方案为： 
一种双进气高效气泵，包括电机，壳体和动力组件，还包括安装在壳体内前端且轴向依次配合串接的下马蹄形隔膜、活塞室下壳体、活塞室上壳体、上马蹄形隔膜、盘形喷气嘴和喷气嘴保护盘，所述喷气嘴保护盘与壳体端面固定连接；所述电机的输出端通过连接器安装在壳体内后端；所述上马蹄形隔膜、下马蹄形隔膜上分别对应设有与活塞室上壳体、活塞室下壳体的进气孔、出气孔相配合的进气开关控制隔膜和出气开关控制隔膜；所述壳体侧壁上形成多个进气凹槽；所述活塞室下壳体的上端面与活塞室上壳体的下端面中心分别设有中心筒，并在以上述轴线为中心的圆周面上配置有若干活塞缸筒；在活塞室下壳体的下端面与活塞室上壳体的上端面上，对应活塞缸筒设有活塞室进气孔和活塞室出气孔；在活塞室下壳体上还设有空心立柱，在活塞室下壳体的下端面上设有空心立柱排气管道孔，所述活塞室下壳体的活塞室出气孔与排气管道的下端气路相通；所述活塞室上壳体的上端面设有中心集气筒，并与上马蹄形隔膜配合形成中央集气室；所述空心立柱上端向上延伸插入活塞室上壳体对应的空心立柱排气管道座孔中，且空心立柱的上端开口处通过内部通孔与中央集气室相连通；
所述活塞室上壳体的的活塞室出气孔与中央集气室相连通；所述动力组件包括波形凸轮和若干双头活塞，所述双头活塞通过在中部设置滑槽与波形凸轮圆周壁活动连接；所述波形凸轮安装在由活塞室下壳体中心筒与活塞室上壳体中心筒组成的中央室内，所述波形凸轮与电机输出轴轴向连接；所述双头活塞安装在由活塞室下壳体活塞缸筒与活塞室上壳体活塞缸筒组成的活塞室内并随着波形凸轮的转动在活塞室内轴向上下移动；所述中央集气室通过盘形喷气嘴向外输气。
作为本发明的进一步改进在于：所述盘形喷气嘴上端面上设有多条蛇状弯曲降噪通路，所述通路的进口与壳体侧壁的进气凹槽相连通，所述通路的出口与活塞室上壳体、上马蹄形隔膜上对应的活塞室进气孔相通。通过设置蛇状弯曲通路降低气流速度，从以减小气流噪音。 
作为本发明的优选实施例：所述活塞室下壳体活塞缸筒与活塞室上壳体活塞缸筒数量分别为5个，且均匀分别。 
作为本发明的进一步改进在于：所述活塞室上壳体、活塞室下壳体的进气孔为指型通道进气孔，进一步减少噪音。 
本发明的工作原理为：依靠活塞垂直气缸做往返运行，先将常压空气从泵底进入侧壁上的进气凹槽形成进气流，进入泵内后分成2股气流，一股从气泵对应的活塞室下壳体的进气孔进入其对应的活塞缸筒，另一路从气泵对应的活塞室上壳体的进气孔进入其对应的活塞缸筒，后经双头活塞压缩增压后排出气缸，经出气孔通过排气管道输送到中央集气腔室后通过喷气嘴喷出。 
本发明的技术特点和显著效果为： 
1、  气路设计为气流从底部通过侧壁进气凹槽进气后再通过泵排出，降低气流阻力，避免产生噪音。
2、  采用波形凸轮和若干双头活塞作为本气泵的驱动，彻底改变了原有气泵采用偏心凸轮作为动力的结构和其存在的缺陷，提高了气泵的稳定性，降低了高速运转时的振动噪音，延长了气泵的使用寿命。 
3、  进气流在泵内分成两路同时进行压缩产生出气流，大大提高了气泵工作效率，而且降低了噪音。 
4、  气泵内部分流气路的设计制造方便，经济性好。 
5、  进气气路设计经过蜿蜒盘曲的蛇状弯曲降噪通路，降低了气流速度，减小了气流噪音。 
6、  活塞室上壳体和活塞室下壳体可形成10个活塞缸筒并组成5个活塞室，通过中心一个波轮带动5个活塞循环工作，结构紧凑，工作效率高。
