本发明的实施方式
[0021] 为了使本实用新型的目的、 技术方案及优点更加清楚明白, 以下结合附图及实 施例, 对本实用新型进行进一步详细说明。 应当理解, 此处所描述的具体实施 例仅仅用以解释本实用新型, 并不用于限定本实用新型。
[0022] 图 1〜图 4示出了本实用新型较佳实施例提供的一种低阻力空气净化器, 如图 1所 示, 该空气净化器包括壳体 1及设置于壳体 1内的风机 2及过滤器 3, 壳体 1上设置 有进风口 12与出风口 11, 壳体 1内形成有导通进风口 12与出风口 11的风道 (未标 号) 。 其中, 过滤器 3相对水平方向倾斜设置、 并位于所述风道靠近进风口 12的 一端, 风机 2位于所述风道靠近出风口 11的一端, 风机 2启动后在过滤器 3处形成 负压, 室内空气通过过滤器 3后跟随风机 2产生的空气流从出风口 11排出。
[0023] 现有的空气净化装置中, 风机位于靠近进风口的一侧, 而过滤器位于靠近出风 口的一侧, 室内空气从进风口进入空气净化装置内部, 并在风机的推动下通过 过滤器, 最后从出风口排出, 故在风机转速不够的情况下, 从过滤器过滤出去 的空气流速不高, 降低过滤器的过滤效果。 此外, 风机启动后产生空气流, 过 滤器位于风机产生的空气流中, 将对空气流产生阻碍作用, 影响整体过滤效果 。 本实施例中, 过滤器 3位于靠近进风口 12的一侧, 风机 2位于靠近出风口 11的 一侧, 风机 2启动后在进风口 12及过滤器 3处形成负压, 室内空气在负压作用下 自进风口 12进入过滤器 3, 故风机 2即使在转速不够的情况下, 也可使经过滤器 3 过滤出去的空气具有较高流速, 有效起到过滤效果, 大大提高过滤器 3的性能。 最后, 通过过滤器 2的空气跟随风机 2产生的空气流从出风口 11排出。 本申请利 用负压原理, 室内空气在负压作用下通过过滤器 3, 使空气运行的阻力小, 在风 机 2转速一定的情况下, 使过滤出去的空气具有较高流速, 从而降低能耗, 环保 节约。
[0024] 如图 1和图 2所示, 壳体 1内设置有风机 2、 过滤器 3、 风机罩 4、 支撑件 5及挡风 板 6。
[0025] 其中, 壳体 1大致为矩形箱体, 进风口 12位于壳体 1的下部, 出风口 11位于壳体 1的上部, 风道形成于壳体 1内、 并用于导通进风口 12与出风口 11, 风机 2及过滤 器 3均位于风道内。 本实施例中, 进风口 12幵设在壳体 1的侧壁面的底部, 可水 平吸入底部空气, 出风口 11幵设在壳体 1的顶部, 向上垂直排气, 这种设计加大 了净化器净化循环的范围, 使净化器对室内空气净化的能力得到了提升。
[0026] 风机 2位于所述风道靠近出风口 12的一端, 其固定在风机罩 4内、 并位于进风口 12的上方。 风机 2启动后在进风口 12与过滤器 3处产生负压、 并形成空气流, 室 内空气自进风口 12进入过滤器 3后经过所述风道从出风口 11排出。
[0027] 风机罩 4用于保护风机 2, 风机罩 4固定在壳体 1的幵设有进风口 12的内侧壁上, 且与相对的另一内侧壁之间形成有间隙, 挡风板 6固定在该间隙内。 风机罩 4上 幵设有分别与风道相连通的第一幵口 41及第二幵口 42, 以使经过滤器 3过滤的空 气从第一幵口 41进入风机罩 4后, 顺着风机 2的转动从第二幵口 42处流出, 进而 从出风口 11排出壳体 1。
[0028] 结合图 2和图 3所示, 风机罩 4包括环形导流板 43及连接在环形导流板 43—侧的 封盖 44, 第一幵口 41幵设在封盖 44上, 第二幵口 42幵设在环形导流板 43上、 并 与出风口 11的位置相对应。 风机 2工作吋, 在环形导流板 43的作用下, 风机 2内 的空气会顺着风机 2的转动而沿着环形导流板 43流出壳体 1。 由上述描述可知, 风机罩 4不仅起到保护风机 2的作用, 还可以使风机 2内的空气更容易顺着风机 2 的转动流出壳体 1. [0029] 过滤器 3位于风道靠近进风口 12的一端, 并相对水平方向倾斜设置。 本实施例 中, 过滤器 3朝向进风口 12的一侧倾斜, 过滤器 3与水平方向的夹角为 40°~80°, 优选的, 过滤器 3与水平方向的夹角为 60°。 采用倾斜安装过滤器 3的优势在于, 相较于垂直或水平放置过滤器 3吋, 不会在壳体 1的底部形成回旋气流, 有利于 壳体 1内空气流动, 并且可在不增加壳体 1前后壁之间宽度或上下高度的情况下 , 使过滤器 3的面积和容积达到更大, 增加净化器的净化能力。
[0030] 支撑件 5固定在壳体 1内, 过滤器 3倾斜地设置在支撑件 5上, 结合图 4所示, 支 撑件 5包括第一支撑部 51、 第二支撑部 52及倾斜部 53。 其中, 第一支撑部 51固定 在壳体 1的底部, 并位于远离进风口 12的一侧; 第二支撑部 52的一端固定在壳体 1的幵设有进风口 12的内侧壁上, 另一端朝远离该内侧壁的一侧延伸; 倾斜部 53 连接在第一支撑部 51与第二支撑部 53之间, 过滤器 3抵接至倾斜部 53上, 倾斜部 53上幵设有与过滤器 3相适配的过气孔 54, 以使气流通过过滤器 3。
[0031] 可以理解的是, 在其它实施例中, 支撑件 5还可以只包括倾斜部 53, 倾斜部 53 的一端连接在壳体 1的内部底面上, 另一端连接在风机 2下方的内侧壁上, 倾斜 部 53上幵设有与进风口 12相连通的过气孔 54。 本实施例并不限定支撑件 5的具体 结构, 只要其使过滤器 3倾斜的设置, 并能使气流通过过滤器 3即可。
[0032] 挡风板 6呈圆弧状, 其一端连接在与风机罩 4相对的另一内侧壁上, 另一端朝靠 近风机罩 4的一侧延伸。 通过过滤器 3的空气在挡风板 6处被遮挡并停留, 之后被 风机 2从封盖 44上的第一幵口 41抽进风机罩 4内, 最后由环形导流板 43上的第二 幵口 42流出。 通过设置挡风板 6, 可有效增加空气流体流经风机 2的速率, 提高 净化效率。
[0033] 综上所述, 实施本实用新型的一种低阻力空气净化器, 具有以下有益效果: 首 先, 本申请的过滤器倾斜设置, 相较于垂直或水平放置过滤器吋, 不会在壳体 的底部形成回旋气流, 有利于壳体内空气流动, 并且可在不增加壳体前后壁之 间宽度或上下高度的情况下, 使过滤器的面积和容积达到更大, 增加净化器的 净化能力。 其次, 过滤器位于靠近进风口的一侧, 风机位于靠近出风口的一侧 , 风机启动后在进风口及过滤器处形成负压, 使室内空气在负压作用下自进风 口进入过滤器, 故本申请利用负压原理, 空气运行的阻力低, 使得风机即使在 转速不够的情况下, 也可使经过滤器过滤出去的空气具有较高流速, 有效起到 过滤效果, 大大提高过滤器的性能。
虽然本实用新型是通过具体实施例进行说明的, 本领域技术人员应当明白, 在 不脱离本实用新型范围的情况下, 还可以对本实用新型进行各种变换及等同替 代。 另外, 针对特定情形或材料, 可以对本实用新型做各种修改, 而不脱离本 实用新型的范围。 因此, 本实用新型不局限于所公幵的具体实施例, 而应当包 括落入本实用新型权利要求范围内的全部实施方式。
