Definitions

  • the invention relates to a muffler for a vacuum cleaner. Background technique
  • the noise reduction of the traditional vacuum cleaner is to increase the tortuosity of the air duct, that is, to use a labyrinth air duct, so that the sound waves lose energy during the propagation process, and the porous sound absorbing material is arranged at the corner of the air duct to absorb the sound energy, thereby
  • the main disadvantage of this structure is that the noise reduction effect is relatively poor.
  • An object of the present invention is to provide a noise reduction device for a vacuum cleaner, which uses one or more noise reduction partitions installed in an air outlet passage, which can greatly reduce the noise emitted by the vacuum cleaner during use.
  • the technical solution of the present invention is: a noise reduction device for a vacuum cleaner, the device includes at least one silencing partition plate installed in an air outlet channel, and the silencing partition plate is provided with small holes.
  • a further technical solution of the present invention is: a noise reduction device for a vacuum cleaner, the device includes at least one silencer partition plate installed in an air outlet channel, and the silencer partition plate is provided with small holes; The direction of airflow in the wind tunnel is vertical.
  • a more detailed technical solution of the present invention is: a vacuum cleaner muffler device, the device includes at least one muffler partition plate installed in the air outlet channel, and the muffler partition plate is provided with small holes; the muffler partition plate is installed to communicate with The direction of air flow in the air outlet channel is vertical; the total ventilation area of the small perforations of the silencing partition is less than 0.5 times the cross-sectional area of the air outlet; the diameter of the small perforations on the silencing partition is less than 6 mm; The thickness of the silencing diaphragm is greater than 0.5 mm.
  • the present invention utilizes one or more silencing partitions installed in the air outlet passage, which can greatly reduce the noise emitted by the vacuum cleaner during use.
  • the silencing baffle of the present invention can be installed separately in the air outlet channel or in the expansion room.

Description

吸尘器消音装置 （2 ) 技术领域
本发明涉及一种用于吸尘器的消音装置。 背景技术
传统的吸尘器的出风消音是通过增加风道曲折性， 也就是采用迷宫式的 风道， 使得声波在传播过程中损失能量， 并且通过风道转弯处安置多孔吸声 材料来吸收声能， 从而达到降噪的目的， 这种结构的主要缺点是消音降噪效 果比较差。 发明内容
本发明的目的是提供一种吸尘器消音装置， 该装置利用安装在出风通道 内的一块或多块消音隔板， 可以大大降低吸尘器在使用时发出的噪音。
本发明的技术方案是： 一种吸尘器消音装置， 该装置包括有至少一块安 装在出风通道内的消音隔板， 消音隔板上布有小孔眼。
本发明进一步的技术方案是： 一种吸尘器消音装置， 该装置包括有至少 一块安装在出风通道内的消音隔板， 消音隔板上布有小孔眼； 所述消音隔板 安装成与出风通道内的气流方向垂直。
本发明更详细的技术方案是： 一种吸尘器消音装置， 该装置包括有至少 一块安装在出风通道内的消音隔板， 消音隔板上布有小孔眼； 所述消音隔板 安装成与出风通道内的气流方向垂直； 所述消音隔板的小孔眼的总透气面积 小于出风通道的截面积的 0.5倍；所述消音隔板上的小孔眼的直径小于 6毫米； 所述消音隔板的厚度大于 0.5毫米。
本发明的优点是：
1 . 本发明利用安装在出风通道内的一块或多块消音隔板， 可以大大降低 吸尘器在使用时发出的噪音。
2. 本发明的消音隔板可以单独安装在出风通道内， 也可以安装在扩张室 中， 扩张室连接在出风通道上， 安装在扩张室中的降噪效果更好。 附图说明
图 1是本发明一优选实施例的吸尘器消音装置的剖面结构示意图， 其中： 标号 Γ表示消音隔板； 2表示小孔眼； 3表示出风通道。 具体实施方式
下面结合图 1所示的本发明的优选实施例对本发明作进一步的描述。
如图 1所示， 一种吸尘器消音装置， 该装置包括有三块安装在出风通道 3 内的消音隔板 1， 消音隔板 1 通常可由塑料或金属制成， 上面布满小孔眼 2， 消音隔板 1 安装成与出风通道 3 内的气流方向基本垂直， 消音隔板 1 的小孔 眼 2的总透气面积小于出风通道 3的截面积的 0.5倍， 消音隔板 1上的小孔眼 2的直径小于 6毫米， 消音隔板 1的厚度大于 0.5毫米。
本发明利用安装在出风通道 3内的一块或多块消音隔板 1， 可以大大降低 吸尘器在使用时发出的噪音。 本发明的消音隔板 1可以单独安装在出风通道 3 内， 也可以安装在扩张室中， 扩张室连接在出风通道 3 上， 安装在扩张室中 的降噪效果更好。
