The height of the blade 433 is equal to the height of the pipe body 311, which effectively improves the sealing effect of the fan blade 43 on the second air outlet hole 31, and enables the pipe body 311 to be against the motor cover 2 at the first air outlet 21, so that the pipe body 311 can better match and fit the first air outlet 21, eliminate installation gaps, further improve the water-proof ability of the main body of the vacuum cleaner, and eliminate noise when the air is discharged.
吸尘器主机壳体3包括沿轴向依次布置的壳体主体32和壳体连接端33，第二出风孔31设置在壳体主体32上，壳体主体32和壳体连接端33之间设置有过渡斜面34，过渡斜面34的设置使得壳体主体32和壳体连接端33之间不会形成容易蓄水的台阶面，提高吸尘器主机的防渗水能力。The main body housing 3 of the vacuum cleaner includes a housing main body 32 and a housing connection end 33 arranged in sequence along the axial direction. The second air outlet hole 31 is provided on the housing main body 32 . There is a transition slope 34. The setting of the transition slope 34 prevents the formation of a step surface that is easy to store water between the housing main body 32 and the housing connection end 33, thereby improving the water seepage resistance of the main body of the vacuum cleaner.
第二出风孔31处的壳体主体32截面呈向外凸起的弧形结构，弧形且向外凸起的截面造型，一方面可以提高壳体主体32的抗压能力，避免壳体主体32变形导致的管体311不能对准第一出风口21，保证吸尘器主机的防渗水能力；另一方面第二出风孔31处的壳体主体32表面不易残留液体，降低吸尘器主机的渗水风险。The section of the housing main body 32 at the second air outlet 31 has an outwardly protruding arc structure. The arc-shaped and outwardly protruding cross-sectional shape can improve the compressive capacity of the housing main body 32 on the one hand and avoid the The pipe body 311 caused by the deformation of the main body 32 cannot be aligned with the first air outlet 21, so as to ensure the anti-seepage ability of the main body of the vacuum cleaner; Risk of water seepage.
工作原理：气流从第一出风口流出电机罩，并通过吸尘器主机壳体上的若干个第二出风孔流出吸尘器。当吸尘器不工作时，扇叶属于关闭状态(封闭第二出风孔)，水渍无法通过第二出风孔进入机器内部；当吸尘器工作时，驱动件通过扇叶连杆驱动所有扇叶同时转动，打开第二出风孔，正常出风。本发明中无需优化机器内部风道即可有效防备水渍从出风口处渗透到机器内，降低风道加工难度，同时保证吸尘器满足喷淋测试(IPX4及以上)的要求。为了保证扇叶对第二出风孔的封闭效果，扇叶转轴卡接在第二出风孔向吸尘器主机壳体内部延伸形成的管体上，叶片设置在管体内，进而使得管体抵在第一出风口处的电机罩上，消除安装缝隙，进一步提高吸尘器主机的防渗水能力，消除出风时的噪音。Working principle: The air flows out of the motor cover from the first air outlet, and flows out of the vacuum cleaner through several second air outlet holes on the main body of the vacuum cleaner. When the vacuum cleaner is not working, the fan blades are in the closed state (closed the second air outlet hole), and water stains cannot enter the machine through the second air outlet hole; when the vacuum cleaner is working, the driving part drives all the fan blades through the fan blade connecting rod at the same time Rotate, open the second air outlet, and let the air flow normally. The present invention can effectively prevent water stains from penetrating into the machine from the air outlet without optimizing the air duct inside the machine, reduce the difficulty of air duct processing, and ensure that the vacuum cleaner meets the requirements of the spray test (IPX4 and above). In order to ensure the sealing effect of the fan blade on the second air outlet hole, the fan blade rotating shaft is clamped on the pipe body formed by the second air outlet hole extending to the inside of the main body of the vacuum cleaner. The motor cover at the first air outlet eliminates the installation gap, further improves the anti-seepage ability of the main unit of the vacuum cleaner, and eliminates the noise when the air is discharged.
