    • PURPOSE: A suction unit of vacuum cleaners is provided to directly absorb the dust by entering a bottom space such as a furniture as an auxiliary suction unit where the height is controlled from the lower part of the main suction unit of the vacuum cleaner by a push operation of a user. CONSTITUTION: A suction unit of vacuum cleaners comprises a main suction unit (10), an auxiliary suction unit (20), and a sliding operation member (30). A sliding unit is formed to the lateral side of the sliding operation member to be in a line with the direction in which the auxiliary suction unit leads in or out. A section control unit is formed on the outer surface of the sliding unit. The section control unit is elastically transformed to the outside relative to the sliding unit in order for the leading in or out section of the auxiliary suction unit is determined.
    • 目的:提供真空吸尘器的抽吸单元,通过进入诸如家具的底部空间作为辅助抽吸单元直接吸收灰尘,其中通过推动从吸尘器的主抽吸单元的下部控制高度 用户的操作。 构成:真空吸尘器的抽吸单元包括主抽吸单元(10),辅助抽吸单元(20)和滑动操作构件(30)。 滑动单元形成在滑动操作构件的横向侧,与辅助抽吸单元引导的方向成直线。 在滑动单元的外表面上形成区段控制单元。 部分控制单元相对于滑动单元弹性变形到外部,以便确定辅助抽吸单元的前进或后部。

    • PURPOSE: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome is provided to remove volatile organic compounds such as formaldehyde, toluene, xylene, and benzene by simply coating the catalyst on the surface of an interior finishing material, and the catalyst can be used semi-permanently without the activity degradation of the catalyst which does not directly react with the other volatile organic compounds or contaminants. CONSTITUTION: A manufacturing method of a nano-oxygen catalyst for removing a sick house syndrome comprises the following steps: the first step of filling titanium tetrachloride and refined water in a ratio of 1:100 in a stainless tank at room temperature, and stirring after adding 0.20-0.39 mol of ammonia water; the second step of extracting a pure titanium dioxide solution, which is a separated lower layer, and filling the stainless tank with the solution; the third step of stirring the mixture after adding 0.23-0.35 mol of nitric acid, and stirring the mixture for 20-50 minutes after additionally adding 0.12-0.25 mol of silica sol; and the fourth step of stirring the mixture after adding 0.013-0.03 mol of acryl binder with minor portions of dispersant and EDTA.
    • 目的:提供一种用于去除病房综合征的纳米氧催化剂的制造方法,通过简单地将催化剂涂覆在内部整理材料的表面上来除去挥发性有机化合物如甲醛,甲苯,二甲苯和苯, 催化剂可以半永久使用,而不会与其它挥发性有机化合物或污染物直接反应的催化剂的活性降解。 构成:用于去除病房综合征的纳米氧催化剂的制造方法包括以下步骤:在室温下在不锈钢罐中以1:1的比例填充四氯化钛和精制水的第一步骤,并在 加入0.20-0.39摩尔氨水; 提取作为分离的下层的纯二氧化钛溶液并用溶液填充不锈钢罐的第二步骤; 在加入0.23-0.35mol硝酸后搅拌混合物的第三步,另外加入0.12-0.25mol二氧化硅溶胶搅拌混合物20-50分钟; 以及在加入0.013-0.03摩尔丙烯酸粘合剂和少量分散剂和EDTA后搅拌混合物的第四步。
