Abstract
(EN) Disclosed is a vacuum cleaner, including: an electric motor (32); an electric motor cover (34), wherein the electric motor (32) is accommodated in the electric motor cover (34), the electric motor cover (34) includes an air inlet (341) and an air outlet (342), and an airflow enters the electric motor cover (34) via the air inlet (341) and leaves the electric motor cover (34) via the air outlet (342); a filter (35), wherein the filter (35) is arranged outside the air outlet (342), and the filter (35) includes a bracket (351) and a filter body (352) mounted on the bracket (351); and a sealing structure (8), wherein the sealing structure (8) is arranged between the bracket (351) and the electric motor cover (34). The vacuum cleaner further includes a shielding structure (9), the shielding structure (9) being arranged between the air outlet (342) and the sealing structure (8). A high-temperature airflow discharged from the air outlet (342) of the electric motor cover (34) is not in direct contact with the sealing structure (8), such that the sealing structure (8) is prevented from being aged due to the influence of the high-temperature airflow, and the service life of the sealing structure (8) is prolonged.
(FR) L'invention concerne un aspirateur, comprenant : un moteur électrique (32) ; un couvercle de moteur électrique (34), le moteur électrique (32) étant logé dans le couvercle de moteur électrique (34), le couvercle de moteur électrique (34) comprenant une entrée d'air (341) et une sortie d'air (342), et un flux d'air entrant dans le couvercle de moteur électrique (34) par le biais de l'entrée d'air (341) et quittant le couvercle de moteur électrique (34) par le biais de la sortie d'air (342) ; un filtre (35), le filtre (35) étant disposé à l'extérieur de la sortie d'air (342), et le filtre (35) comprenant un support (351) et un corps de filtre (352) monté sur le support (351) ; et une structure d'étanchéité (8), la structure d'étanchéité (8) étant disposée entre le support (351) et le couvercle de moteur électrique (34). L'aspirateur comprend en outre une structure de protection (9), la structure de protection (9) étant disposée entre la sortie d'air (342) et la structure d'étanchéité (8). Un flux d'air à haute température évacué par la sortie d'air (342) du couvercle du moteur électrique (34) n'est pas en contact direct avec la structure d'étanchéité (8), de telle sorte que le vieillissement de la structure d'étanchéité (8) par l'influence du flux d'air à haute température est prévenu, et la durée de vie de la structure d'étanchéité (8) est prolongée.
(ZH) 一种吸尘器,包含:电机(32);电机罩(34),电机(32)收容于电机罩(34),电机罩(34)包含进风口(341)及出风口(342),气流由进风口(341)进入电机罩(34),由出风口(342)离开电机罩(34);过滤器(35),过滤器(35)设置于出风口(342)外,过滤器(35)包含支架(351)及安装于支架(351)的过滤体(352);密封结构(8),密封结构(8)设置于支架(351)及电机罩(34)之间;吸尘器还包含遮挡结构(9),遮挡结构(9)设置于出风口(342)及密封结构(8)之间。电机罩(34)的出风口(342)排出的高温气流不会直接与密封结构(8)接触,从而避免密封结构(8)由于高温气流影响而老化,延长密封结构(8)的使用寿命。
