3 to 6, an embodiment of the present invention provides a portion to be used as a handle, and has a connecting body (1) capable of engaging and separating the friction cleaning member, by generating a rotational force in the interior A body portion 3 provided to the connecting body 1; An extension coupling means provided in the body portion 3; A coupling cover 5 coupled to the extension coupling means; An extension shaft (7) supported by the coupling cover (5) in a rotatable state, the one end of which is capable of switching a state in which the coupling body (1) is coupled and separated; It comprises a friction cleaning member (9) connected to the extension shaft (7) to receive a rotational force.

The body portion 3 is provided with a motor and a battery therein, and an operation switch for controlling the driving of the motor, and a detergent pump may be built therein so as to spray the detergent by itself. This configuration uses known techniques.

3 to 6, the extension coupling means is made of a male screw portion 11 formed on the circumferential surface of the body portion 3, and the coupling cover 5 is a female screw portion fastened to the male screw portion 11. It is formed in the cylindrical shape provided with (13).

Therefore, the user is screwed by rotating the coupling cover 5 with respect to the body portion 3, wherein the extension shaft (7) is precisely tailored to receive a rotational force from the connecting body (1) It must be combined in a true state.

In this embodiment, the structure in which the extension shaft 7 is coupled to the connector 1 uses a conventionally known technique as shown in FIG.

An extension pipe 15 integral with the coupling cover 5 is provided outside the extension shaft 7, and the friction cleaning member 9 is provided at the end of the extension pipe 15. End body 17 is supported to be rotated by the rotational force transmitted from).

That is, in a state in which the coupling cover 5 is coupled to the body portion 3, the body portion 3 and the end body 17 are integrally formed through the extension pipe 15.

3 shows a 2-1 gear 19 mounted to the end body 17 and driven by the extension shaft 7; 2-2 gears (21) meshed with the 2-1 gears (19) and rotated with a rotation axis parallel to the extension shaft (7); A 2-1 friction cleaning member 23 which is integrally connected to the 2-2 gear 21 and rotates to form the friction cleaning member 9; An idler gear 25 installed at the end body 17 to be engaged with the 2-1 gear 19; 2-3 gears (27) meshed with the idler gears (25) and rotated in a rotational axis parallel to the extension shaft (7); A structure including a 2-2 friction cleaning member 29 which is integrally connected to the 2-3 gear 27 and rotated to form the friction cleaning member 9, wherein the friction cleaning member 9 is the 2-1. It consists of two of a friction cleaning member 23 and a 2-2 friction cleaning member 29.

If the 2-1 gear 19 rotates clockwise, the 2-2 gear 21 rotates the 2-1 friction cleaning member 23 counterclockwise, and the idler gear 25 is half It is rotated clockwise to rotate the 2-3 gear 27 clockwise so that the 2-2 friction cleaning member 29 is rotated clockwise.

As a result, the 2-1 friction cleaning member 23 and the 2-2 friction cleaning member 29 are rotated in opposite directions to each other, which is applied to the frictional force acting as the friction cleaning member 9 from the portion to be cleaned during cleaning. The reaction force is canceled with each other to prevent the body portion 3 from attempting to rotate by the reaction force so that the user can use it more conveniently.

4 shows a case in which the friction cleaning member is composed of three, 3-1 gears 31 installed on the end body 17 and driven by the extension shaft 7; A 3-1 friction cleaning member 33 which is integrally connected to the 3-1 gear 31 and rotates to form the friction cleaning member 9; A 3-2 gear 35 which is meshed with the 3-1 gear 31 and rotated in a rotational axis parallel to the extension shaft 7; A 3-2 friction cleaning member 37 which is integrally connected to the 3-2 gear 35 and rotates to form the friction cleaning member 9; An idler gear 25 installed in the end body 17 to be engaged with the 3-1 gear 31; 3-3 gear (39) which is meshed with the idler gear (25) and rotated with a rotation axis parallel to the extension shaft (7); The 3-3 friction cleaning member 41 is integrally connected to the 3-3 gear 39 and rotates to form the friction cleaning member 9.

Therefore, when the 3-1 gear 31 and the 3-3 gear 39 is rotated in the clockwise direction, the 3-2 gear 35 and the idler gear 25 is rotated in the counterclockwise direction, the 3- 1, the friction cleaning member 33 and the 3-3 friction cleaning member 41 is rotated in the same direction, and the 3-2 friction cleaning member 37 is rotated in the opposite direction to clean.

5 is a 4-1 gear 43 mounted to the end body 17 and driven by the extension shaft 7; A 4-1 friction cleaning member 45 which is integrally connected to the 4-1 gear 43 and rotates to form the friction cleaning member 9; 4-2 gears (47) meshed with the 4-1 gears (43) and rotated in a rotation axis parallel to the extension shaft (7); A 4-2 friction cleaning member 49 which is integrally connected to the 4-2 gear 47 and rotates to form the friction cleaning member 9; 4-3 gears (51) meshed with the 4-1 gears (43) and rotated in a rotation axis parallel to the extension shaft (7); A 4-3 friction cleaning member 53 connected integrally to the 4-3 gear 51 and rotating to form the friction cleaning member 9; 4-4 gears (55) meshed with the 4-2 gears (47) and rotated in a rotation axis parallel to the extension shaft (7); It is integrally connected to the 4-4 gear 55 is rotated and comprises a 4-4 friction cleaning member (57) forming the friction cleaning member (9).

The 4-1 friction cleaning member 45, the 4-2 friction cleaning member 49, the 4-3 friction cleaning member 53 and the 4-4 friction cleaning member 57 have a square shape on the same plane. Since the 4-1 gear 43 is meshed with the 4-2 gear 47 and the 4-3 gear 51 at the same time to transmit rotational force, the 4-2 gear 47 and Since the 4-3 gear 51 is rotated in a direction opposite to the rotation direction of the 4-1 gear 43, the 4-4 gear 55 receives the rotational force from the 4-2 gear 47, If the 4-1 gear 43 has the same rotational direction as a result, the 4-1 friction cleaning member 45 and the 4-4 friction cleaning member 57 are rotated in the same clockwise direction. The friction cleaning member 49 and the 4-3 friction cleaning member 53 are rotated counterclockwise.

That is, the 4-1 friction cleaning member 45, the 4-2 friction cleaning member 49, the 4-3 friction cleaning member 53 and the 4-4 friction cleaning member 57 form a quadrilateral with each other. The diagonal directions are rotated in the same direction but rotated in the opposite direction to adjacent ones so that the reaction force acting from the part to be cleaned can be canceled as much as possible, so that unnecessary rotational force is not felt by the user's hand holding the body 3. It is to enable quiet and stable use.

Of course, in the embodiment of the two to four friction cleaning member 9 as described above, the friction cleaning member is the body portion 3 by the extension pipe 15 and the extension shaft 7 and the end body 17, etc. It is operated by receiving the rotational force from a position far away from the tip, so that it is easy for the user to clean deep and contaminated areas such as the inside of the toilet.

That is, the end pump (59) provided in the end body 17 for storing and spraying detergent; It further includes an operating rod 61 connected from the end pump 59 to the body portion 3 to drive the end pump 59.

The end pump 59 stores detergent and allows the detergent to be ejected from the end pump 59 when the operating rod 61 is pulled by the user. The operating mechanism itself is a known sprayer or the like. Same as the pump.

The body portion 3 may be provided with a separate pump that can be stored in the detergent itself in the inside of the body 3 to spray the detergent to the front of the body portion 3 by the user's operation, the present invention is parallel to this By providing a separate end pump 59 in the end body 17, by the operating rod 61 in the body portion 3 by the user operating the operating rod 61 by the end pump 59 By allowing the detergent to be sprayed, it is possible to accurately spray the detergent to the cleaning part even when the friction cleaning member 9 operates at a position far from the body 3 as in the present invention.
