Description

一种低噪音气囊 技术领域
本实用新型涉及一种气囊充气结构，特别是涉及一种低噪音气囊。
 背景技术
目前按摩保健产品气压按摩是一个主要的按摩方式，通过气泵、气阀、气囊以及控制***来控制气囊的充放气实现挤压式按摩，即通过气泵对气囊间隙性的充气和放气实现按摩功能。为满足消费者对按摩器械舒适度的要求，按摩器械应具备良好的静音性能，其中随着技术进步，用于按摩器械的电机、气泵等驱动部件已能达到较好的静音效果，然而用于按摩器械的气囊机构在充气所产生的噪音仍未得到有效解决。此外，在医疗器械和充气床等使用气囊的装置也同样存在上述问题。有鉴于此，特提出本申请。
 技术问题
本实用新型针对现有技术的不足而提出一种低噪音气囊，从而解决了现有气囊充气慢的同时噪音很大的问题。
技术解决方案
本实用新型提供了一种低噪音气囊，包括气嘴1、进气腔帽2、吸音棉3和软体气囊5；所述气嘴1与所述进气腔帽2连接，所述吸音棉3设置于所述进气腔帽2与所述软体气囊5围成的膨胀空腔21内，所述软体气囊5上设置有第一进气孔51。
气流通过所述气嘴1进入膨胀空腔21内后，气流透过所述吸音棉3后从所述第一进气孔51进入所述软体气囊5内部。
 有益效果
通过采用上述技术方案，本实用新型可以取得以下技术效果：与现有技术相比，该低噪音气囊通过在进气腔帽与所述软体气囊围成的膨胀空腔内设置有吸音棉，在软体气囊上设有第一进气孔，从而使得气流透过吸音棉后从所述第一进气孔进入所述软体气囊内部，该低噪音气囊结构简单，制造安装方便，在保证气囊充气效率的同时，可有效降低充气噪声。
 附图说明
图1绘示了本实用新型实施例的一种低噪音气囊的结构示意图。
图2绘示了图1中的一种低噪音气囊的另一结构示意图。
图3绘示了图1中的一种低噪音气囊的剖面结构示意图。
图4绘示了图1中的一种低噪音气囊的外部结构示意图。
 本发明的最佳实施方式
为了使本实用新型的目的、技术方案和优点更加清楚，下面将结合附图对本实用新型作进一步地详细描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本实用新型保护的范围。
结合图1-4，本实用新型实施例提供了一种低噪音气囊，包括气嘴1、进气腔帽2、吸音棉3和软体气囊5；所述气嘴1与所述进气腔帽2连接，所述吸音棉3设置于所述进气腔帽2与所述软体气囊5围成的膨胀空腔21内，所述软体气囊5上设置有第一进气孔51。
气流通过所述气嘴1进入膨胀空腔21内后，气流透过所述吸音棉3后从所述第一进气孔51进入所述软体气囊5内部。
其中，气嘴1与气管11连接。
本实用新型所述的低噪音气囊，进气时，高速气流通过气嘴进入膨胀空腔内后气体流速降低，气体透过吸音棉后通过第一进气孔进入所述软体气囊内部。通过膨胀腔和吸音棉的共同作用，达到降低充气噪声的目的。
进一步地，在一个实例中，如图2所示，由于气流流动会推动吸音棉稍微移动，为了气囊充气效果降噪效果更佳，在所述膨胀空腔21内还设置有固柱体22，所述固柱体22均匀分布于所述吸音棉3周围，以避免所述吸音棉3在气流的作用下移动。
如图2所示，进气腔帽2通过粘接等方式直接安装在软体气囊5 的外侧，软体气囊5上开有进气孔，吸音棉3安装在进气腔帽2内。
进一步地，在另一个实例中，如图1所示，无需设置多个固柱体22，可通过设置环形压盘4固定吸音棉3，具体地，所述环形压盘4与所述进气腔帽2围成膨胀空腔21，所述环形压盘4上设置有第二进气孔41，所述环形压盘4将所述吸音棉3固定于所述膨胀空腔21内，以避免所述吸音棉3在气流的作用下移动。环形压盘4固接于软体气囊上，具体可通过热压或粘接等方式安装于所述软体气囊5内侧，进气腔帽2和环形压盘4固定连接，具体可通过螺纹连接以保证连接强度和气密性。
当然为了使得充气气流能够充分进入软体气囊内部，则吸音棉3位于所述第一进气孔51或第二进气孔41的正上方，具体可如图1-3所示。
进一步地，在一个实例中，如图1和图2所示，所述吸音棉3在所述膨胀空腔21内的位置距离气嘴1的距离大于预设距离。例如，吸音棉距离进气腔帽2进气口有3mm以上的距离，在降低充气噪声，同时保证充气和排气效率。
进一步地，在一个实例中，如图1-3所示，所述第一进气孔51或第二进气孔41的半径大于气嘴1进气口的半径的预设倍数。具体地，第一进气孔51或第二进气孔41的半径大于气嘴1进气口的半径的1.5倍，使得保证充气和排气效率的基础上显著降低气囊充气噪声，结构简单，成本较低。
另外，需要说明书的是，本实用新型的低噪音气囊的进气腔帽中的结构，包括吸音棉、气嘴、气孔等结构、位置及安装关系不仅可以应用到按摩椅等按摩器材上，还可以应用在可利用气体起伏的床垫类产品上，凡是包含本实用新型的低噪音气囊的方案均在本实用新型的保护范围之内。
尽管已描述了本申请的优选实施例，但本领域内的技术人员一旦得知了基本创造性概念，则可对这些实施例作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施例以及落入本申请范围的所有变更和修改。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的精神和范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本申请也意图包含这些改动和变型在内。
