Description

一种高效散热的直驱空压机 技术领域
本实用新型涉及空压机技术领域，尤其涉及一种高效散热的直驱空压机。
背景技术
便携式空压机是一种通过对气体加压使气体输出压缩的装置。随着人们生活水平的提高，便携式空压机已经越来越多的应用到日常生活中。例如为汽车轮胎、自行车、气球充气，露营时为充气床垫、充气座椅等充气。
现有技术的直驱式空压机一般通过在电机的后端输出轴处设置有散热风扇，通过电机的旋转带动散热风扇进行转动，从而实现对电机及相关发热组件的散热。而空压机在工作的过程中，充气机芯中的活塞气缸组件产生的热量较多，而在活塞气缸组件中，其气缸盖的温度往往是最高的。现有直驱式空压机的散热结构，电机的后端往往对散热风扇所产生的风形成阻挡，导致风量不能有效的在散热风道内进行流动，并不能有效的对活塞气缸组件进行散热，导致内部温度过高，往往导致胶管松脱、活塞磨损等等现象的发生，降低空压机的使用寿命。
因此，有必要对现有的直驱式空压机进行改进。
实用新型内容
本实用新型的目的在于针对现有技术的不足提供一种高效散热的直驱空压机，有效的散发空压机内部的热量，提高空压机的使用寿命。
为实现上述目的，本实用新型的一种高效散热的直驱空压机，包括外壳，所述外壳内部设置有充气机芯，所述外壳内部设置有散热风道，所述充气机芯位于散热风道内，所述外壳设置有进风口和出风口，所述进风口和出风口连通于散热风道，所述进风口和/或出风口设置有用于散发充气机芯所产生的热量的散热风扇。
作为优选，所述充气机芯包括驱动电机，所述驱动电机的前端连接有活塞气缸组件，所述活塞气缸组件位于进风口，所述驱动电机的后端位于出风口，所述散热风扇设置于进风口并朝向活塞气缸组件。
作为优选，所述活塞气缸组件包括气缸，所述气缸的顶部连接有气缸盖，所述散热风扇位于进风口与气缸盖之间。
作为优选，所述进风口开设于外壳的侧方。
作为优选，所述充气机芯包括驱动电机，所述驱动电机的两端均连接有活塞气缸组件，所述外壳内部设置有两个散热风道，两个活塞气缸组件分别设置两个散热风道内，两个散热风道均设置有散热风扇；所述活塞气缸组件的顶部朝向于进风口，所述活塞气缸组件的底部朝向于出风口，所述散热风扇位于进风口并朝向活塞气缸组件的顶部。
作为优选，所述活塞气缸组件包括气缸，所述气缸的顶部连接有 气缸盖，所述散热风扇位于进风口与气缸盖之间。
作为优选，所述进风口位于外壳的顶部，所述出风口位于外壳的底部。
作为优选，所述外壳的进风口和/或出风口设置有卡槽，所述散热风扇插接于所述卡槽内。
本实用新型的有益效果：本实用新型的一种高效散热的直驱空压机，包括外壳，外壳内部设置有充气机芯，外壳内部设置有散热风道，充气机芯位于散热风道内，外壳设置有进风口和出风口，进风口和出风口连通于散热风道，进风口和/或出风口设置有用于散发充气机芯所产生的热量的散热风扇，通过单独设置的散热风扇，散热风扇直接从进风口抽取空压机外部的冷却空气进入散热风道，冷却空气对充气机芯进行散热，散发的热量从出风口排出，在出风口处也可以设置散热风扇，此散热风扇进行抽风，抽取内部的热空气。因此独立设置的散热风扇能有效的在散热风道内带走充气机芯所产生的热量，尤其是活塞气缸组件的热量，实现高效散热，提高空压机的使用寿命。

具体实施方式
以下结合附图对本实用新型进行详细的描述。
如图1至图2所示，本实用新型的一种高效散热的直驱空压机，包括外壳1，所述外壳1内部设置有充气机芯2，所述外壳1内部设置有散热风道3，所述充气机芯2位于散热风道3内，所述外壳1设置有进风口11和出风口12，所述进风口11和出风口12连通于散热风道3，所述进风口11和/或出风口12设置有用于散发充气机芯2所产生的热量的散热风扇4。通过单独设置的散热风扇4，散热风扇4直接从进风口11抽取空压机外部的冷却空气进入散热风道3，冷却空气对充气机芯2进行散热，散发的热量从出风口12排出，在出风口12处也可以设置散热风扇4，此散热风扇4进行抽风，抽取内部的热空气。因此独立设置的散热风扇4能有效的在散热风道3内带走充气机芯2所产生的热量，尤其是活塞气缸组件22的热量，实现高效散热，提高空压机的使用寿命。
本实施例的充气机芯2包括驱动电机21，所述驱动电机21的前端连接有活塞气缸组件22，所述活塞气缸组件22位于进风口11，所述驱动电机21的后端位于出风口12，所述散热风扇4设置于进风口11并朝向活塞气缸组件22。如图1所示，散热风扇4单独设置于进 风口11，在进风口11处抽取空压机外部的冷却空气直接对高温的活塞气缸组件22进行散热，活塞气缸组件22的大部分热量被带走。
具体地，活塞气缸组件22包括气缸221，所述气缸221的顶部连接有气缸盖222，所述散热风扇4位于进风口11与气缸盖222之间。由于气缸盖222处所产生的热量是最多的，散热风扇4直接对气缸盖222进行吹风，有效带走气缸盖222的大部分热量，避免气缸盖222与连接胶管的松脱。
作为优选，所述进风口11开设于外壳1的侧方。该进风口11可以设置于外壳1的不同位置，主要是配合散热风道3的设置。将进风口11设置于外壳1的侧方，可保证外壳1外观的完整性与及生产制造的工艺性。
作为优选，所述外壳1的进风口11和/或出风口12设置有卡槽13，所述散热风扇4插接于所述卡槽13内。通过卡槽13的设置，便于散热风扇4的安装固定，结构简单。
通过独立设置的散热风扇4能有效的在散热风道3内带走充气机芯2所产生的热量，实现高效散热，大大提高空压机的使用寿命。
实施例二。
如图3至图5所示，本实施与实施例一的不同之处在于，本实施例的空压机为双缸式直驱空压机，本实施例的充气机芯2包括驱动电机21，所述驱动电机21的两端均连接有活塞气缸组件22，所述外壳1内部设置有两个散热风道3，两个活塞气缸组件22分别设置两个散热风道3内，两个散热风道3均设置有散热风扇4；所述活塞气缸组 件22的顶部朝向于进风口11，所述活塞气缸组件22的底部朝向于出风口12，所述散热风扇4位于进风口11并朝向活塞气缸组件22的顶部。通过双气缸221的设置能大大提高充气速度，但是对散热的性能提出进一步的要求。本实施例通过在不同的活塞气缸组件22处设置对应的散热风扇4，对各自活塞气缸组件22进行单独的散热，形成双散热风道3的进风与出风，满足双气缸221充气机芯2的散热需求。
本实施例的活塞气缸组件22包括气缸221，所述气缸221的顶部连接有气缸盖222，所述散热风扇4位于进风口11与气缸盖222之间。该散热风扇4正对气缸盖222，可以对温度最高的气缸盖222进行有效的散热，避免连接胶管的脱落。
作为优选，所述进风口11位于外壳1的顶部，所述出风口12位于外壳1的底部。空压机在工作过程中，外部的冷却空气从空压机顶部的进风口11进入，再由位于外壳1底部的出风口12排出，避免热空气喷向于使用者，结构布局较为合理。
本实施例的其余部分与实施例一相同，这里不再赘述。
以上内容仅为本实用新型的较佳实施例，对于本领域的普通技术人员，依据本实用新型的思想，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实用新型的限制。
