Abstract

Embodiments described herein relate to a base chamber closed by a cover having a support that receives a liquid-repellent refill of any commercially available model, which separates the chamber at the bottom for accommodating the reservoir from the upper part for the wick which, duly heated by a PTC heating device, has the stream of air directed to the release windows where negative pressure conveys the repellent towards the blades of the fan. In further exemplary embodiments, the device aims to optimize steam releasing from the repellent contained in the refill into the chamber to the environment by way of a hose connected to a tube projecting from said chamber to an oblique support located at the front of the top finish of the column of the fan, where the negative pressure is more pronounced.

DETAILED DESCRIPTION

[0049] Referring to exemplary FIGS. 1-9, the BASE CHAMBER AND COVER WITH DIFFUSER FOR REPELLENT REFILL USE IN A FAN described in exemplary embodiments herein, refers to a base chamber (1) closed by a cover (2) having a support (3) which houses a liquid repellent refill (4) of any model available on the marker, which separates the chamber at the bottom (11) for accommodating the reservoir (4R) and upper part (1S) for the wick (4P), which is suitably heated by a PTC heating device (5) has the airflow directed towards the release windows (6) where negative pressure takes the repellent toward the blades of the fan (7).

[0050] More particularly, the base chamber (1) is located in the lower front portion of the fan column. The fastening of the chamber to the fan is made by way of plastic locks and screws. Access to the interior of the base chamber occurs by removing the cover (2) which is then reinserted for closing. This system facilitates the insertion and replacement process of the repellent refill, which is attached to a support (3) fixed in the said cover (2), which is fitted to the product inside the chamber (1) by way of steering guides (8). In this way, the chamber (1) houses the cover (2) with the support (3) together with the repellent refill (4).

[0051] The reservoir (4R) of the liquid repellent refill is housed at the bottom (11) of the chamber which is similar in shape to the repellent refills available on the market to be compatible with all models. In turn, the wick (4P) is housed in the upper part (1S) of the chamber. In this region, the U-shaped heating and dispersion system is also set to receive, house the wick (4P) and allow heat transfer as necessary. Once the repellent refill (4) is connected, the heating system generates the heat needed to vaporize the liquid of the repellent refill. Due to the location of the repellent refill (4), this vapor is directed to the release windows (6) of the cover (2). Due to the movement of the blade a negative pressure is created in front of the column. This pressure draws the steam evaporating from the refill (4) and directs it to the blades of the fan (7) which spreads it into the environment in a well-distributed, optimized and efficient manner. The base chamber (1) for use with liquid repellent refill (4) in a fan is closed to restrain excessive air inflow, thus avoiding the dilution of the repellent steam, allowing the repellent steam to flow out only through the release windows (6) located on the cover (2) of the chamber (1).

[0052] The base chamber (1) for use of the liquid repellent refill (4) in a fan (7) is located inside the front portion of the fan column and is constituted by the chamber (1) itself, the cover (2) with a support (3), heating and dispersion system and electric heating system. As already discussed the chamber (1) at the bottom (11) housing the reservoir (4R) of the liquid repellent refill, while the upper part (1S) houses the heating wick (4P) and also the heating and dispersion system (4A). Guides (8) directing and housing the support (3) of the repellent refill (4) project between the two housings. At the bottom (11) of the chamber there is a base (9) which is used for fastening to the column of the fan (7). The cover (2) of the chamber (1) is movable and has release windows (6) allowing the passage and directing the outflow of the steam evaporating from the repellent refill (4). The cover (2) further has an embedded support (3) of the refill (4), allowing its fitting and fastening. This support (3) also separates the upper part (1S) from the bottom (11) of the base chamber (1), thus restricting the steam evaporating from the refill (4) to the upper part (1S) only, and consequently due to the little space in said housing, directing the flow towards the release windows (6).

[0053] The heating and dispersion system comprises the heating base (10) housing the electrical system and the upper cover (11) of the chamber, which covers and protects the electrical system and closes the chamber. These two elements are U-shaped to receive the repellent refill from the front of the chamber and are also hood-shaped to direct the evaporating steam directly to the release windows (6). The heating system of the repellent refill (4) is constituted by a PTC heating device (5) suitably attached to a U-shaped metal plate (12) which provides heat for heating the wick (4P). The plate (12) is U-shaped to allow and facilitate the insertion and replacement of the liquid repellent refill (4). The electrical connection is performed by way of a terminal connected to one side of the PTC heating device (5), while the other is connected to the metal plate (12), thus allowing the passage of electric current between said plate (12) and the PTC heating device (5). This configuration avoids the use of a second terminal in the PTC heating device (5), prevents loss of heat and optimizes the space of the heating system. The product control has a key that switches on the heating system only if the fan (7) is also switched on to promote optimization and greater efficiency of the liquid repellent.

[0054] In another exemplary embodment, and referring now to exemplary FIGS. 10-16, the BASE CHAMBER AND COVER WITH DIFFUSER FOR USE OF REPELLENT REFILL IN A FAN, may be provided to optimize steam exhausting from the repellent contained in refill (100) into chamber (200) to the environment by way of a hose (300) connected to a tube (400) projecting from said chamber (200) to an oblique support (500) located at the front of top finish (600) of column (700) of the fan, where negative pressure is more pronounced.

[0055] Further, this exemplary embodiment, addresses a lifting of outlet point (800) by an interposition of hose (300) connected to tube (400) projected from an upper part (200S) of the base chamber to oblique support (500) localized in the front part of the top finish (600) of the column (700) of the fan. The arrangement of the tube (400) and the oblique support (500) does not favor the folding of the hose (300), which would interrupt the flow of the repellent therein. In this context, the hose (300) between the heating and dispersion system, located in the upper part of the chamber (200S), and the upper outlet point (800) in the column of the fan, located behind the propeller, an area where negative pressure is more pronounced and therefore the efficiency of repellent distribution is optimized. The highest point (800) also reduced the condensation of the repellent within the chamber.
