Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a carpet cleaning nozzle, which uses an aerosol detergent for carpets to easily remove stains from carpets, and when used for cleaning, the hand lever for supplying detergent is accidentally operated. This provides a safe carpet cleaning nozzle that does not eject detergent even when pulled.

Conventionally, carpet cleaning nozzles use liquid detergent, and a fixed brush is placed in contact with a rotating brush driven by an air turbine, and the liquid detergent is dripped onto the fixed brush to form foam. Although it has been developed, the foaming effect was not necessarily satisfactory under load fluctuations such as the type of carpet.

- The present invention solves the above-mentioned conventional drawbacks, and one embodiment thereof will be described below based on FIGS. 1 to 5.

In Figs. 1 to 5, 1 is a nozzle body, 2 is an air turbine that rotates with suction airflow, 3 is a rotating brush with brushes planted on its surface, 4 is a belt connecting the air turbine 2 and the rotating brush 3, and 5 is a belt that connects the air turbine 2 and the rotating brush 3. The air turbine chamber 6 houses the air turbine 2; the rotary brush chamber 6 houses the rotary brush 3; 1 opens to the outside at a position below the rotary brush 3 and facing the floor; A lower opening 8 opens in a position not facing the floor surface and communicates with the air turbine chamber 5, and 9 selectively connects either the lower lower part or the upper opening 8 to the air turbine chamber 5. 10 is a switching lever protruding from the outside of the nozzle body 1 to operate this switching valve 9, 11 is an aerosol detergent tank, and 12 is a detergent tank to which this aerosol detergent tank 11 is detachably attached. A fixed frame, 13 is a detergent tank fixing protrusion made of an elastic material, 14 is a pressure lever that pushes the detergent spouting part 1γ of the aerosol detergent tank 11 by pulling a wire 15 with a hand lever 16, and 18 is a pressure lever 1
4 is a tension spring urging the opposite direction; 19 is a nozzle body 1;
A more protruding suppression lever support plate, 20 is a wire tube, 2
1 is a wire stopper for fixing the wire tube 20 to the extension tube 22, and 23 is a wire lock plate, which can be locked by a wire lock rod 24 integrated with the switching valve 9.

In the above configuration, the nozzle body 1 is connected to the extension tube 22, and the hand lever 16 and the wire tube 20 are connected to the wire stopper 2.
Stop at 1.

When cleaning a carpet, the aerosol detergent tank 11 is inserted and fixed into the detergent tank fixing frame 12.

If the switching lever 10 is tilted to the cleaning side, the switching valve 9 is switched to take in air from the upper opening 8, as shown in FIG.

When the vacuum cleaner is turned on, the air turbine 2 starts rotating.

Then, the rotational brush 3 starts rotating at the same time due to the deceleration transmitted by the belt 4.6 When the hand lever 16 is pulled, the suppression lever 14 pushes the detergent spouting part 11, so the foamed detergent is transmitted along the front wall of the nozzle body 1 and onto the carpet. come out.

Therefore, the rotating brush 3 can clean the carpet with bubbles on its surface.

When cleaning a carpet, when the switching lever 10 is moved to the cleaning side, the switching valve 9 switches to guide the intake air from the lower part of the carpet to the air turbine chamber 5, and the rotating brush 3 sucks up the dust on the carpet while stirring it up. Therefore, it can be cleaned easily.

In this case, in order to prevent detergent from being dispensed by pulling the hand lever 16, in this embodiment, a wire lock plate 23 and a wire lock rod 24 are installed as shown in FIGS.
A safety mechanism is adopted.

That is, as shown in FIG. 4, when the switching lever 10 is tilted to the cleaning side, the wire lock plate 23 freely passes over the wire lock rod 24, so the operation of the suppression lever 14 is controlled by the operation of the hand lever 16. However, as shown in FIG. 5, when the switching lever 10 is tilted toward the cleaning side, the hand lever 16 cannot be pulled because the wire lock rod 24 prevents the movement of the wire lock plate.

As described above, according to the present invention, it is possible to wash or clean the carpet easily and safely with the aerosol detergent tank loaded, and it is also possible to prevent the aerosol detergent from being accidentally released onto the carpet. The effect is extremely canine.
