Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the rotary mop cleaner 1 according to the present invention includes a handle 10, a multi-stage stick 20 formed below the handle 10 and the cleaning base 30. . The handle 10 has a built-in control panel (not shown) for controlling the operation of the cleaning body 30, the multi-stage stick 20 is coupled to the cleaning body 30 is formed to variably adjust its length . In addition, the inside of the multi-stage stick 20 is formed in a hollow shape, as shown in FIG. 3, a cable 31 twisted into a coil shape or a soft straight cable is inserted to supply or control external power to the cleaning main body 30. It is configured to carry a signal. That is, the cable 31 is formed to penetrate the inside of the multi-stage stick 20 to be connected to the driving motor, unlike the general case in which the power cable is inserted into the main body. Prevents the phenomenon.

In addition, the cleaning main body 30 is coupled to the support plate 370 and a pair of mop rotation shafts 367 disposed to be spaced apart from each other on the support plate 370, a pair of mop rotation plate 380, the support plate 370 is rotatably provided. Is coupled to the upper surface of the mop rotation unit 380 for rotating the pair of mop rotating plate 380 includes a cover member 340 and the like.

The support plate 370 is provided in a curved plate shape as an example of the present invention. The mop pivot unit 360 is disposed above the support plate 370, and a pair of mop rotation shafts 367 of the mop pivot unit 360 are installed to penetrate the support plate 370. A pair of mop rotating plate 380 is coupled to the lower region of the pair of mop rotating shaft 367 is disposed spaced apart from each other. The support plate 370 is formed long in the left and right directions so that the pair of mop rotating plate 380 is spaced apart in the left and right directions as an example of the present invention.

As shown in FIG. 2, the support plate 370 and the cover member 340 are coupled to each other by a band-shaped shock absorber 350, thereby mitigating external shocks to the cleaning base 30, and cleaning the cleaner. It is possible to prevent scratches and breakage of the body upon contact with the body and other objects.

As shown in FIG. 10, while the mop 390 rotates by the mop rotation shaft 367 of the mop rotation unit 360 at the bottom edge of the support plate 370, the foreign matter moves around the support plate 370 or the mop rotation shaft 367. The foreign matter prevention jaw 374 protruding downward along the edge may be provided to prevent the inflow.

The pair of mops 390 are provided in a disc shape so that the bottom surface can be easily cleaned in contact with the bottom surface to be cleaned. The mop 390 will be described in detail later with reference to FIGS. 11 to 17.

Velcro tape coupling portion 381 to which the Velcro tape is attached to the bottom of the mop rotating plate 380 is formed to be recessed in the circumferential direction in a plurality of shallow depths on the bottom of the mop rotating plate 380, and Velcro The tape coupling portion 381 is formed with a plurality of protruding pins 382 protruding higher than the depth of depression of the Velcro tape coupling portion 381. Therefore, when the velcro tape coupled to one side of the mop 390 is disposed in the velcro tape coupling portion 381, a through hole through which the protruding pin 382 penetrates is formed and is seated on the velcro tape coupling portion 381. Thus, even if the mop cleaner 1 is stored without the attachment of the mop 390, the Velcro tape attached to the Velcro tape coupling portion 381 by the protruding pin is pressed to prevent the adhesion force to the mop from being reduced later. When the 390 is attached and used, it is possible to prevent the Velcro tape from being separated or lost by the rotational force of the rotating mop 390. In the illustrated figure, the Velcro tape coupling portion 381 is formed in four places, and two protrusion pins 382 are formed at each coupling portion 381, but the number is not limited thereto.

In addition, the edge of the mop rotating plate 380 has a relatively thin mop rotating plate shock absorbing jaw (383) is provided for the shock absorption to serve to cushion the external shock, outside the mop rotating plate shock absorbing jaw (383) The mop swivel plate wing portion 384 extending along the circumferential direction is the edge of the mop 390 in the vertical direction of the mop swivel plate 380 when the mop 390 hits a wall or other obstacle during use of the mop 390. It can be easily folded to prevent the phenomenon that the mop 390 is separated.

The mop rotation unit 360 includes a drive motor 361 mounted on the upper surface of the support plate 370, a pair of rotation shafts 362 extending from both sides of the drive motor 361, and having a worm gear part 363 formed thereon. A pair of wheel gears 365 are coupled to the pair of mop rotation shafts 367 and rotated by the worm gear part 363.

The driving motor 361 is disposed in the center area of the upper surface of the support plate 370. In addition, the driving motor 361 uses a biaxial motor equipped with a pair of rotating shafts 362 on the main body of the driving motor 361 as an example of the present invention, but is not limited thereto. Two drive motors may be used.

The worm gear part 363 is formed in the end region of the pair of pivot shafts 362 to be coupled to the pair of wheel gears 365 respectively to rotate the wheel gears 365. Therefore, the pair of rotating shafts 362 of the present invention is provided with a worm gear part 363 as a separate member and is integrally formed with the rotating shaft 362, rather than being configured to be coupled to the rotating shaft 362. The 363 may be provided as a separate member to reduce noise or vibration generated when the 363 is coupled to the pivot shaft 362.

The wheel gear 365 is coupled to a pair of mop rotation shaft 367 is rotated by the worm gear portion 363. In addition, the pair of wheel gears 365 are rotated in opposite directions by the worm gear part 363. Therefore, the pair of mop rotating shaft 367 and the pair of mop rotating plate 380 is rotated in the opposite direction. That is, the mop rotating plate 380 by the mop rotating unit 360 is rotated in different directions. Thus, in the rotary mop cleaner 1 according to the present invention, since the pair of mop rotating plates 380 rotate in different directions, the pair of mop prevents the tipping phenomenon in which the mop tries to proceed in the rotation direction when the mop rotates in one direction. We can do it and can use more conveniently.

The mop rotation unit 360 is disposed in close proximity to the pair of wheel gears 365 with the worm gear part 363 interposed therebetween on the upper surface of the support plate 370, and a pair of auxiliary parts rotated by the worm gear part 363. It may further include a wheel gear (369).

The pair of auxiliary wheel gears 369 are disposed on the opposite side of the wheel gear 365 with the worm gear portion 363 of the pivot 362 in the middle (see FIG. 4). In addition, the pair of auxiliary wheel gears 369 are coupled to the rotating shaft disposed on the upper surface of the support plate 370 without rotating the separate mop rotation shaft 367 to be idling by the worm gear part 363. Thus, by providing a pair of auxiliary wheel gear (369), it is possible to prevent the worm gear portion 363 from being separated from the wheel gear 365 during rotation to rotate the pair of mop rotating plate 380 more stably. You can. However, according to an embodiment of the present invention, when the bearings 362a and 367a and the bearing sealing materials 362b and 367b are inserted into the rotation shaft 362 and the mop rotation shaft 367, as described below, a pair of auxiliary wheel gears are provided. 369 may be omitted.

In addition, the holder 368 is interposed between the lower part of the mop rotating shaft 367 and is coupled to the rotating shaft coupling portion 381 of the mop rotating plate 380. The holder 368 may be formed of a synthetic resin or metal material resistant to heat. If the mop rotating shaft 367 and the mop rotating plate 380 are directly coupled without the holder 368, the mop rotating plate 380 in which heat generated from the mop rotating shaft 367 that rotates at high speed is formed of a conventional plastic material. By being directly transmitted to the rotating shaft coupling portion 381, the rotating shaft coupling portion 381 is fused to bring about a deterioration of the function of the mop rotating plate 380. Therefore, heat generated from the mop rotating shaft 367 that rotates at high speed is coupled to the rotating shaft coupling portion 381 of the mop rotating plate 380 via the holder 368 made of a heat resistant material, thereby preventing damage to the rotating shaft coupling portion 381 due to heat. It can be prevented it is possible to extend the service life of the mop rotating plate (380).

The mop rotation unit 360 of the rotary mop cleaner 1 according to the present invention may further include a gear case 364 covering the worm gear part 363, the wheel gear 365 and the auxiliary wheel gear 369. .

The gear case 364 is provided as a pair so that each one of the gear cases 364 is disposed on both sides with the driving motor 361 interposed therebetween. The gear case 364 according to an embodiment of the present invention is further provided with a worm gear fixing part 364a and a wheel gear fixing part 364b. In the worm gear fixing part 364a and the wheel gear fixing part 364b, bearings 362a and 367a and bearing sealing materials 362b and 367b coupled to the rotation shaft 362 and the mop rotation shaft 367 are inserted, respectively. By such a configuration, the gap between the worm gear 363 and the wheel gear 365 can be accurately maintained. That is, if there is no such configuration, the flow is generated in the gap between the worm gear 363 and the wheel gear 365 during use, and if the clearance is narrow, the worm gear 363 and the wheel gear 365 is in close contact with the wheel gear 365 Heat is generated in the wheel gear 365, which causes the wear of the wheel gear 365 to be easily worn, which shortens the cleaner life and generates noise. When the clearance is too wide, the worm gear 363 comes into contact with the thin gear of the wheel gear 365, thereby causing the wheel gear ( 365 wears easily. In addition, when the mop rotation shaft 367 is subjected to resistance during use, the worm gear 363 is bent, so that the play with the wheel gear 365 is far from the thin gear portion of the wheel gear 365, and wear occurs easily. Therefore, the gear case 364 forms the worm gear and the wheel

gear fixing parts

364a and 364b so that when the bearings 362a and 367a are inserted, the gap between the worm gear 363 and the wheel gear 365 is always accurately maintained and the wheel gear ( To prevent the shortening of the service life of 365 and inserting the bearing sealing materials 362b and 367b formed of an elastic material such as rubber surrounding the bearings 362a and 367a, vibrations are prevented by driving the wheel gear 365. To eliminate noise.

The gear case 364 is not limited to the illustrated form, and may be provided as one to cover the entire mop rotation unit 360 including the driving motor 361. The gear case 364 may be configured to be coupled to the support plate 370 by a bolt or the like. The gear case 364 may be mainly formed of a plastic material, or may be provided of a metal plate material. Thus, the rotary mop cleaner 1 according to the present invention can reduce the noise and the like by providing a gear case 364, it can be beautiful in appearance.

In the rotary mop cleaner 1 according to the present invention, a ball joint part 310 is formed to connect the multi-stage stick 20 to be rotatably coupled to the support plate 370, and the ball joint part 310 has a lower ball. Locking pin coupling provided on the spherical ball 311 and the spherical ball 311 and the spherical ball extending portion 314 and the spherical ball 311 that is attached to extend upward from the spherical ball 311 and the upper end is combined with the multi-stage stick (20) A spherical ball support plate 313 is coupled to the groove 315 and the fingerboard 370 to accommodate the spherical ball 311 and to support the spherical ball 311 not to be separated.

Spherical ball support plate 313 is coupled to the support plate 370, the multi-stage stick 20 is provided in a hemispherical shape in which the central area is recessed so that the rear and left and right directions can be rotated and the spherical ball 311 is settled. The locking pin coupling groove 315 is provided in a hole shape so that the upper end of the locking pin 331 to be described later may protrude.

The locking unit 330 is disposed in the spherical ball 311 of the rotary mop cleaner 1 according to the present invention so that the multi-stage stick 20 can stand in a standing state with respect to the support plate 370.

As shown in FIG. 7, the locking unit 330 includes a locking pin 331 having a spring (not shown) inserted therein, a locking pin fixing part 332 for fixing the locking pin 331, and a locking pin high. Supporting the government 332 and includes a locking unit support plate 333 is fixed to the spherical ball (311).

The locking pin 331 is composed of a hemispherical upper end, and because the spring is built in the locking pin 331 will always protrude upward through the locking pin coupling groove 315. However, when the pressure is applied to the end of the locking pin 331 from the outside it can be recessed into the locking pin coupling groove 315. The lower portion of the locking pin 331 is coupled to the locking pin fixing portion 332 and the locking pin fixing portion 332 is coupled to the locking unit support plate 333 so that the locking unit 330 is attached to the inside of the spherical ball 311. It is arranged to be.

The spherical ball 311 is disposed on the spherical ball support plate 313 while the locking unit 330 is fixed to the spherical ball 311, and the spherical ball cover 320 is fixed to the spherical ball support plate 313. Done. The inside of the spherical ball cover 320 is provided with a locking depression 321 that protrudes into the locking pin coupling groove 315 to maintain the multi-stage stick 20 in an upright position.

The locking depression 321 is provided in the hemispherical recessed so that the end of the hemispherical locking pin 331 is coupled, the locking pin guide rail 322 is provided on the inner surface of the spherical ball cover 320 in the left and right directions. The locking pin 331 naturally moves along the locking pin guide rail 322 when the multi-stick 20 is rotated in the left and right directions. The position of the locking recess 321 is preferably provided in the central region of the locking pin guide rail 322.

Thus, when the multi-stage stick 20 is rotated from side to side in order to store the multi-stage stick 20 in a standing state, the locking pin 331 is bound to the locking recess 321 at a certain time with a binding sound so that the multi-stage stick 20 20) is in a standing state.

In the present invention, the state in which the multi-stage stick 20 stands up refers to a state in which the multi-stage stick 20 is disposed in an upward direction, and is not an accurate vertical state.

As shown in FIG. 9, the cover member 340 of the rotary mop cleaner 1 according to the present invention is rearward and left and right with respect to the support plate 370 in a state in which the multi-stage stick 20 stands up with respect to the support plate 370. And a ball joint guide 341 disposed in pairs so as to be spaced apart from each other so as to be rotatable in the direction.

The ball joint guides 341 are installed in a pair to be spaced apart from each other on one side of the cover member 340, the spherical ball extension portion of the ball joint portion 310 when rotating back in the state where the multi-stage stick 20 is standing ( 314 is configured to pass between them. Thus, guided by a pair of ball joint guide 341, the user can extend the handle 10 extending from the multi-stage stick (20) because the multi-stage stick (20) can be easily rotated without shaking in the rear. Grasping the support plate 370 is rotated backwards and can be easily cleaned.

In addition, when the multi-stage stick 20 is rotated to the left or right in the standing state, the locking pin 331 naturally flows along the locking pin guide rail 322 provided in the spherical ball cover 320 and mops in a narrow space. You can clean it by pushing it.

Hereinafter, the configuration of the mop 390 coupled to the rotary mop cleaner 1 according to the present invention will be described in detail with reference to FIGS. 11 to 17.

11 is a perspective view showing a state in which the rag 390 is attached to the bottom of the cleaning main body 30 according to an embodiment of the present invention. As shown, it can be seen that the mop 390 is formed in a circular shape wider than the outer periphery of the bottom of the cleaning main body 30.

Referring to FIG. 12, the bottom of the cleaning main body 30 is shown, and the mop 390 is attached to the Velcro tape coupling portion 381 attached to the mop rotating plate 380 disposed on the bottom of the cleaning main body 30. The bottom surface of the mop 390 is attached to the Velcro tape. As described above, the Velcro tape coupling portion 381 is formed with a protruding pin 382 to prevent the Velcro tape from being pressed and to prevent the attached mop 390 from being removed during use.

FIG. 13A illustrates a cleaning surface of the mop 390, and FIG. 13B illustrates a rear surface of the cleaning surface, which is coupled to the Velcro tape.

Referring to FIGS. 13 to 16, the mop 390 is formed with an inner cleaning surface 391 in which brushed fibers for wiping the bottom surface are woven, and an edge portion 392 having a thickness thicker than that of the inner cleaning surface 391. The friction fiber layer 391a of the inner cleaning surface 391 is formed by mixing fibers having a high friction force and fibers having a low friction force at a predetermined ratio or alternately weaving them. Microfiber yarn is used in one embodiment of the present invention as a high friction fiber, and the fiber is twisted in the shape of pretzel to maximize the friction force as shown in enlargement at t, and a general frictional yarn is used as the low friction fiber. If the microfiber yarn and the normal PE yarn are alternately woven to the friction fiber layer 391a of the inner cleaning surface 391 and subjected to the dyeing process, the degree of reaction during dyeing is different, so that a striped pattern is naturally formed as shown in FIG. This can improve the aesthetics of the mop. As such, the use of a high friction fiber and a low fiber is mixed with a high friction force, and the cleaner receives excessive force by the strong rotational force of the mop rotating plate 380, and the force is transmitted to the motor. This is because it is not easy to use.

In addition, a Velcro cloth layer 391c attached to the Velcro tape coupling portion 381 is formed on the rear surface of the cleaning surface shown in FIG. 13B. In addition, a sponge layer 391b is further formed between the friction fiber layer 391a and the velcro cloth layer 391c of the inner cleaning surface 391, so that a thick sponge of a cushion type is formed so that the moisture stays long and the slightly curved bottom surface is in close contact. The built-in can increase the efficiency of mop cleaning. In addition, it is preferable that the constituent layers of the rag 390 formed of a plurality of layers are bonded to each other so as not to be separated or lifted up, and a sewing line 393 is formed to bond the respective constituent layers. Here, the shape of the sewing line 393 is not limited to the cross shape shown.

On the other hand, the inner cleaning surface 391 of the mop 390 has a high frictional force with the bottom surface during rotation. Therefore, it may be desirable to increase the efficiency of mop cleaning by forming a cavity 394 in a portion as shown in FIG. 14 to slightly reduce frictional force. The cut surface may be stitched to prevent loosening of the ol.

The edge portion 392 is formed to have a thicker thickness than the inner cleaning surface 391 as described above. This is when there is no edge portion 392, when used to attach to the mop rotating plate when the mop rotating plate 380 hit the protrusion of the bottom surface to be cleaned by the rotation force mop 390 is not easily separated or absorb the shock mop rotating plate ( 380) can cause damage. Therefore, by forming the edge portion 392 thicker than the inner cleaning surface (391) to prevent the phenomenon that the mop 390 is pushed out during cleaning, and can be easily folded vertically in the direction of the mop rotating plate 380 even when hitting other structures. A buffer zone may be secured to protect another structure or the mop rotating plate 380. The edge portion 392 is a woven fabric using a round wrapping method along the outer edge A of the inner cleaning surface 391 so as to be formed thicker than the inner cleaning surface 391 as shown in FIGS. 15 and 16. Stitching while rolling both sides of the inner surface may be made to have a thicker than the inner cleaning surface (391). In this case, since the outer portion A of the inner cleaning surface 391 is sewn to prevent loosening, the edge portion 392 may be manufactured to have a higher stiffness than the inner cleaning surface 391 with a sense of thickness. The fabric used for forming the edge portion 392 may also be formed by alternately weaving a high friction fiber and a low friction fiber.
