The inlet port body 100 includes a body portion (not shown) including a driving portion for generating a suction force for collecting and collecting dust including general dust, fine dust, foreign matter, and the like, And forms a rectangular shape on the lower part of the dust inlet 110. [

At least two or more wheels 102 for facilitating the movement of the suction port body 100 are provided at the bottom edge of the suction port body 100. The other end of the intake port body 100 is connected to the body portion (not shown in the figure) to connect the path of the dust and the terminal 106 to which electrical and control signals are transmitted .

The dirt suction port 110 is connected to a first path 111 for directly sucking dirt located on the floor to be cleaned and transferring the dirt to a body portion (not shown), and at the same time, light dirt including fine dust And a second path 112 for sucking and transporting the same.

One end of the second path 112 is connected to the first path 111 and the other end of the second path 112 is formed to have the same or similar length as the length of the brush roller 130.

The anti-scattering film 113, which blocks the dust scattered from the rotating roller 120 from scattering, is formed in the other end portion of the second path 112 at the same time in an arched or arc shape have.

In other words, the anti-scattering film 113 has an arch shape to surround a part of the circumference of the brush roller while being in contact with the opened upper part of the waste collection cylinder 190 at one end, 112 are connected to each other.

At both longitudinal end portions of the dirt suction port 110 and at an intermediate position in the width direction thereof, grooved whirling portions 114 are formed which are curved in S-shape and whose one side is opened.

The whirlpool 114 forms a whirlwind having a groove shape having a depth (a) formed at a value selected from the range of 1 to 5 millimeters and a relatively strong 2.5 millimeter (error 0.5 millimeter) with the lower reference plane of the inlet body .

When used for general household use, the value of depth (a) is less than 2.5 millimeters, it is difficult to suck large sized dirt, often clogged, and a large value results in low suction power. However, it is natural that depth (a, b) values can be adjusted depending on the use environment.

It is further preferable that the grooves of the whirlpool part 114 form an S-shaped inclination on the side surface to form a whirlwind.

Meanwhile, the upper portion of the suction port body 100 is provided with a suction cut-off portion 115 for blocking the first path 111 by the control so that the dust inlet 110 can not suck the dirt.

The suction blocking portion 115 includes a suction blocking button 117, a suction blocking film 118, and a suction blocking jaw 119.

The suction cutoff button 117 is installed on the suction port body 100 so that one side of the suction cutoff button protrudes from the upper side of the suction port body 100 to the inside of the first path 111 and receives a control signal from the user or the outside.

The suction cut-off button 117 may hold a protruded state, maintain the inserted state when inserted by an external control signal, and maintain the protruded state by protruding again.

One side of the suction blocking membrane 118 is provided in an interlocked state on the other side of the suction blocking button 117 and has a shape to block or open the first passage 111 in a closed state.

The suction blocking membrane 118 may block or open the first path 111 in a closed state by a mechanical hinge coupling generally known with the suction blocking button 117 or by installing a separate electric control device.

The suction blocking film 118 closes the first path 111 by a corresponding control signal applied to the suction blocking button 117 to block or prevent the dirt from being sucked into the dirt suction port 110, And sucked into the suction port 110.

The suction blocking jaw 119 is installed inside the first path 111 and supports the state in which the first path 111 is closed by the suction blocking layer 118.

The suction blocking portion 115 closes or opens the first path 111 and includes a generally known structure.

The rotary roller 120 is installed at a lower side of the lower end of the suction port body 100 to be cylindrical and absorbs dirt by moisture. The roller 120 includes a roller body 121, a water groove 122, a water leakage blocking layer 123, (124), and a first rotation shaft (127).

The roller body 121 has a cylindrical shape centered on the first rotation axis 127, and is made of silicon, microfiber cloth, leather, etc., and is excellent in hygroscopicity and adsorption property, and has a thickness of 6 to 12 millimeters.

The roller body 121 has a cylindrical shape but forms a helical groove to have a twisted shape, so that the cleaning effect can be further enhanced according to the kind of the dirt.

The water grooves 122 are grooves formed at both ends of the cylindrical roller body 121 around the first rotating shaft 127 and formed of a cylindrical body and moisture 146 adhered to the surface of the roller body 121 Thereby preventing the roller body 121 from being detached.

The leakage shielding film 123 is installed inside the suction port body 100 and has a circular arc shape at one lower end thereof and is fixed in a state of being inserted into the water groove 122 and the moisture 146 adhered to the surface of the roller body 121, Thereby preventing the roller body 121 from being detached.

The water groove 122 and the water leakage preventing film 123 function to prevent or prevent the moisture 146 located on the surface of the roller body 121 from separating from the roller body 121. The roller body 121 has a constant The moisture 146 located on the surface may attempt to escape.

The water jaw 124 is formed on the outer side of the water groove 122 in the shape of a cylinder (or disk) centering on the first rotation shaft 127 and supports the water leakage preventing membrane 123 installed to prevent it from moving. The diameter of the water jaw 124 is preferably larger than the diameter of the roller body 121.

That is, it is possible to suppress or prevent the moisture from separating from the water groove 122 first, from the water leakage preventing film 123 secondarily, and from the water jaw 124 third.

The first rotating shaft 127 is a central axis extending in both the longitudinal direction of the rotating roller 120 and rotating the rotating roller 120.

At both ends of the first rotating shaft 127, an elastic part 116 that generates an elastic force in the up-and-down direction is provided to buffer shocks or vibrations applied from the bulky dirt during the cleaning process.

The elastic portion 116 is provided on the suction port body 100 to smoothly overcome an impact applied to the first rotating shaft 127 and to pass the obstacle smoothly. The elastic portion 116 is also provided on the second rotating shaft 137, which is the rotating shaft of the brush roller 130 It is natural that it can be installed in the same manner.

The brush roller 130 is installed at one side of the lower inner end of the suction port body 100 and has a cylindrical shape centered on the second rotation shaft 137 and has one or more spiral brushes 131 provided on the outer peripheral surface thereof.

Alternatively, the brushes 131 may be installed at uniform intervals on the entire outer circumferential surface of the brush roller 130, so that the brushes 131 are shown in various forms in the drawings.

The brush roller 130 is disposed adjacent to the rotating roller 120 in a state in which the outer peripheral portion of the brush roller 130 is in close contact with the rotating roller 120.

The brush roller 130 serves to scrape off the dirt adsorbed by the rotating roller 120 using the moisture from the surface of the rotating roller 120. Therefore, always clean the surface of the rotating roller 120).

At this time, light dirt among the dirt falling from the surface of the rotary roller 120 by the brush roller 130 is sucked into the second path 112, and the heavy dirt collects in the dirt collecting container 190.

In addition, the dirt separated from the surface of the rotating roller 120 by the brush roller 130 is prevented from being scattered by the scattering prevention film 113, so that the dust is scattered and is kept clean without being contaminated by the dust.

The moisture supply part 140 is provided with a water pump 143 fixed to the rotation belt 147 provided in a rotatable state in which the water supply part 140 rotates and moves within a range of 360 degrees on one side of the outer peripheral surface of a small- The liquid 142 of the liquid crystal panel 141 is periodically supplied as moisture 146 to the surface of the rotating roller 120 rotating by the control signal using the water pump 143.

The moisture supply portion 140 is configured to include a container 141, a water pump 143, a nozzle 144, a supply pipe 145, and a rotating band 147.

It is preferable that the container 141 is made of a plastic material which is transparent and has a relatively strong impact on the impact, so that the container 141 is easy to attach and detach from the water pump 143 in a state in which the liquid 142 is not leaked.

The water pump 143 is configured to discharge the liquid 142 in the container to the discharge portion by a corresponding control signal, and it is relatively preferable to use a plunger pump.

The supply pipe 145 is a pipe or a pipe connected to the discharge port of the water pump 143 and is a path through which the discharged liquid 142 is transferred and a nozzle 144 is installed at the end of the discharge path.

The nozzle 144 is configured to spray or spread the liquid 142 supplied through the supply pipe 145 to the mist 146 in the form of mist, so as to spread or spread in a wide area, and is composed of two or more.

The rotating band 147 is installed in a rotatable state in which the rotating band 147 rotates within a range of 360 degrees on one side of a portion having a relatively small diameter among the outside of the inlet port body 100. Since the water pump 143 is fixed to the rotating band 147, the container 141 including the water pump 143 can rotate the outer peripheral surface of the inlet port body 100. It is assumed that the rotation is performed by rotating within a range of 360 degrees.

The first blades 150 are formed of two pieces (one pair) and each have a V shape as a whole. The first blades 150 are made of rubber, synthetic resin or the like, and have moisture 146 applied to the surface of the rotating roller 120. [ Or to prevent leakage, movement, or departure of the battery. In one embodiment, it is a configuration for wiping off moisture or moisture like a window brush of an automobile.

Each V-shaped first blade 150 has an advantage in that moisture is collected at the center of the rotating roller 120 along the moving direction. Therefore, it is relatively preferable that the V shape is installed so as to gather moisture in the center.

In addition, the first blade 150 has a V-shaped configuration to reduce frictional resistance due to foreign substances, to increase the cross-sectional area of application of the moisture to increase the absorbency of the roller body 121, Thereby reducing the rotational resistance of the rotating roller 120, which may be caused by dirt adhered to the rotating roller 120.

The second blade 160 is installed at one side of the lower end of the suction port body 100 and sucks the dirt suction port 110 and scoops up the dirt remaining on the floor after the rotating roller 120 is adsorbed by moisture Rubber or a synthetic resin material.

When the fine dust removing vacuum cleaner 10 moves forward, the second blade 160 scatters dirt from the bottom and moves the dust collected by the second blade 160 backward when the vacuum cleaner 10 for dust removal is moved backward The cleaning roller 120 is attracted or the dust inlet 110 is sucked in. Thus, the cleaning effect is further increased or doubled.

The driving means 170 is installed at one side of the inlet body 100 and provides rotational power to the rotating roller 120 and the brush roller 130.

The drive means 170 includes a one-way gear 171, a first circular gear 172, a drive gear 173, a drive motor 174, and a second circular gear 175.

The unidirectional gear 171 is fixed to the first rotating shaft 127 of the rotating roller 120. When the rotating driving force is applied in the forward direction, the unidirectional gear 171 rotates the rotating roller 120 in the forward direction, Is not transmitted to the first rotary shaft (127).

The unidirectional gear 171 generally has the same configuration as a freewheel used in a bicycle or the like (a shaft splicer having a structure that transmits power only in one direction) and has a disc shape.

The first circular gear 172 is fixed on a circular outer circumferential surface of the unidirectional gear 171 in the form of a disk and forms a disk, and forms a tooth on the outer circumferential surface.

The drive gear 173 forms a tooth on the outer circumferential surface that meshes with the teeth of the first circular gear 172 and transmits the rotational driving force to the first circular gear 172.

The rotational driving force transmitted from the driving gear 173 by the first circular gear 172 is transmitted to the first rotating shaft 127 through the one-way gear 171, thereby rotating the rotating roller 120 in one direction.

The driving motor 174 rotates the driving gear 173 by being coupled with the driving gear and outputting the rotational driving force generated by the control signal to the driving gear 173.

The second circular gear 175 has a disk shape and is fixed to one end of the second rotation shaft 137 of the brush roller 120 and the teeth formed on the outer peripheral surface of the disk engage with the driving gear 173, ≪ / RTI >

The rotational driving force transmitted by the second circular gear 175 rotates the brush roller 130.

The gear ratio of the first circular gear 172 to the driving gear 173 is set to be larger than the gear ratio of the second circular gear 175 to the driving gear 173 so that the rotary roller 120 rotates more than the brush roller 130 It is configured to rotate relatively slowly.

The circuit unit 180 is installed at one side of the suction port body 100 and senses the rotating state of the rotating roller 120 to control the moisture supplying unit 140 to periodically supply moisture to the surface of the rotating roller 120.

The circuit unit 180 includes a roller position sensing unit 183, a cleaning control unit 184, and an ultraviolet ray unit 185.

The roller position sensing unit 183 includes a position display unit 181 disposed at one end of the rotation roller 120 for outputting a signal capable of detecting a rotation state of a wheel, a detector 181 for detecting the position of the position display unit 181, (182).

The roller position sensing unit 183 senses (detects) the rotation of the rotation roller 120 by one rotation and notifies the cleaning control unit 184 of the rotation.

The cleaning control unit 184 receives the signal detected by the roller position sensing unit 183 and controls the moisture supply unit 140 to periodically supply moisture to the surface of the rotation roller 120, And controls the driving means 170 so that the roller 130 is driven.

That is, the cleaning control unit 184 periodically controls the moisture supply unit 140 to supply moisture to the surface of the rotating roller 120 every time the rotating roller 120 rotates one wheel. Here, it is of course possible to control so that the moisture is supplied more than once every time one rotation is required.

The ultraviolet ray unit 185 outputs an optical signal for sterilization by the control signal of the cleaning control unit 184. [

The means for outputting the sterilizing optical signal is not shown for the sake of simplicity but it is preferable to install at least one inside the suction inlet body 100 and around the rotating roller 120 and the brush roller 130 .

The dirt collecting box 190 has a rectangular hexahedron shape, and one side surface in the longitudinal direction is partially opened. At one end of the opening, the dirt collecting box 190 is attached to the surface of the rotating roller 120, The third blade 195 is installed in a detachable state.

The dirt collecting box 190 collects dirt collected from the surface of the rotating roller 120 by the brush roller 130 and collects the collected dirt.

At this time, the relatively light dirt including the fine dust is sucked in the second path 112 among the dirt out of the brush roller 130, and relatively heavy dirt is collected in the dirt collecting bin 190.

10, the rotary roller 120, the brush roller 130, and the dirt collecting cylinder 190 are fixedly installed and easily separated from the suction port body 100 by the operation of the separation lever 108, For example.

The rotary roller 120 and the brush roller 130 should be replaced if they are worn out for a long period of time. Also, if they are stained or dirty, they should be cleaned separately.

The separation lever 108 is configured to easily install and separate the rotary roller 120, the brush roller 130, and the dirt collecting cylinder 190 on the inlet port body 100, ) Structure, it is needless to say that the separating lever 108 may not be constituted.

The present invention having the above-described structure can complete the cleaning of the wet-cloth without exchanging or replacing the wet-cloth until the rotary roller is worn and replaced, and the cleaned place is not contaminated because the wet-cloth does not rotate in the reverse direction during cleaning.

In addition, by pushing and pulling the dirt on the floor, it separates or falls off and removes it by sucking or sucking. Therefore, the cleaning effect is further enhanced. Even if the cleaning time is long or the area to be cleaned is wide, the surface of the wet cloth is kept clean.

In addition, the moisture (moisture) on the surface of the wet-cloth is kept constant by the moisture repeatedly supplied periodically, and the cleaning effect of the wet-cloth to clean the dirt including the fine dust is maintained until the completion of the cleaning.

In addition, since the whirlpool 114 is formed at both edges of the dust inlet 110 that forms a rectangular shape, whirlwind is generated, so that the dust including the surrounding fine dust can be strongly sucked.

On the other hand, a sterilizing treatment can be performed with an optical signal by ultraviolet rays or the like on a part of a rotating roller, a brush roller, or the like which is in direct contact with the dirt.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
