AIR PURIFYING VACUUM CLEANER SYSTEM
First Claim
1. An air purifying system for a vacuum cleaner, comprising:
- an airflow reduction chamber insertable along an airflow passage of the vacuum cleaner so that air pumped by the vacuum cleaner passes in the airflow reduction chamber prior to being released out in the open, the airflow chamber having an air inlet, an air outlet, and an inner wall extending between the air inlet and the air outlet;
an air deflector plate positioned in front of one of the air inlet and the air outlet inside the airflow reduction chamber;
a UV lamp extending inside the airflow reduction chamber on a side of the air deflector plate opposite to said one of the air inlet and the air outlet, the UV lamp being of a type emitting radiations killing germs and bacteria, at least a portion of the inner wall of the airflow reduction chamber extending at a level of the UV lamp having a surface reflective to the radiations emitted by the UV lamp; and
a control circuit for controlling operation of the UV lamp.

Abstract
An air purifying system for a vacuum cleaner. An airflow reduction chamber is insertable along an airflow passage of the vacuum cleaner so that air pumped by the vacuum cleaner passes in the airflow reduction chamber prior to being released out in the open. The airflow chamber has an air inlet and an air outlet and an inner wall extending therebetween. An air deflector plate is positioned in front of one of the air inlet and the air outlet inside the airflow reduction chamber. A UV lamp of a type emitting radiations killing germs and bacteria extends inside the airflow reduction chamber. At least a portion of the inner wall of the air chamber at a level of the UV lamp has a surface reflective to UV radiations emitted by the UV lamp. A control circuit controls operation of the UV lamp.

15. A method of purifying air in a vacuum cleaner, comprising the steps of:
-
creating an airflow reduction chamber along an airflow passage of the vacuum cleaner so that air pumped by the vacuum cleaner passes in the airflow reduction chamber prior to being released out in the open, the airflow chamber having an air inlet, an air outlet, and an inner wall extending between the air inlet and the air outlet; producing an airflow reduction inside the airflow reduction chamber by positioning an air deflector plate in front of one of the air inlet and the air outlet inside the airflow reduction chamber; controlling emission of radiations capable of killing germs and bacteria inside the airflow reduction chamber using a UV lamp extending inside the airflow reduction chamber on a side of the air deflector plate opposite to said one of the air inlet and the air outlet; and increasing an effect of the radiations emitted by the UV lamp by reflection of the radiations inside the airflow reduction chamber against at least a surface portion of the inner wall of the airflow reduction chamber extending at a level of the UV lamp.
