Abstract
(EN) An electric purification device (100), an air purifier and a range hood. The electric purification device (100) comprises an adsorption electrode (10), a discharge electrode pin (20) and a discharge electrode tip (30). The discharge electrode pin (20) is at least partially inserted into the adsorption electrode (10). An air channel (11) for air to pass through is formed between the discharge electrode pin (20) and the adsorption electrode (10). The discharge electrode tip (30) is positioned in the air channel (11) and arranged on an outer wall of the discharge electrode pin (20), wherein the discharge electrode pin (20) has a cylindrical structure and a cleaning hole (21) connected to the cylindrical cavity of the discharge electrode pin (20) is provided on the cylindrical wall of the discharge electrode pin (20). The adsorption electrode (10) is cleaned using cleaning fluid ejected from the cleaning hole (21) to solve the problem that the electric purification device (100) is inconvenient to clean.
(FR) L'invention concerne un dispositif de purification électrique (100), un purificateur d'air et une hotte aspirante. Le dispositif de purification électrique (100) comprend une électrode d'adsorption (10), une broche d'électrode de décharge (20) et une pointe d'électrode de décharge (30). La broche d'électrode de décharge (20) est au moins partiellement insérée dans l'électrode d'adsorption (10). Un canal d'air (11) pour le passage de l'air est formé entre la broche d'électrode de décharge (20) et l'électrode d'adsorption (10). La pointe d'électrode de décharge (30) est positionnée dans le canal d'air (11) et disposée sur une paroi externe de la broche d'électrode de décharge (20), la broche d'électrode de décharge (20) ayant une structure cylindrique et un trou de nettoyage (21) relié à la cavité cylindrique de la broche d'électrode de décharge (20) étant disposé sur la paroi cylindrique de la broche d'électrode de décharge (20). L'électrode d'adsorption (10) est nettoyée à l'aide d'un fluide de nettoyage éjecté à partir du trou de nettoyage (21) pour résoudre le problème selon lequel le dispositif de purification électrique (100) est peu pratique à nettoyer.
(ZH) 一种电净化装置(100)、空气净化器及油烟机,电净化装置(100)包括吸附极(10)、放电极针(20)以及放电极尖端(30),放电极针(20)的至少部分穿设在吸附极(10)内,放电极针(20)与吸附极(10)之间形成供气体通过的气体通道(11);放电极尖端(30)位于气体通道(11)内,放电极尖端(30)设置在放电极针(20)的外壁上;其中,放电极针(20)为筒状结构,放电极针(20)的筒壁上设置有与放电极针(20)的筒腔连通的清洗孔(21),以通过由清洗孔(21)喷出的清洗液对吸附极(10)进行清洗,从而解决电净化装置(100)不便于清洗的问题。
