Vacuum Cleaner with Rotary Brush {VACUUM CLEANER WITH BRUSH}

The present invention relates to a vacuum cleaner equipped with a rotary brush, and more particularly, is equipped with a brush that can be rotated along the periphery of the bottom surface of the suction portion of the cleaner to improve the rotational power of the brush in performing water cleaning using detergent solution The present invention relates to a vacuum cleaner for smoothly supplying detergent liquid for brush cleaning.

In general, the vacuum cleaner connects the hose to the suction port of the main body where the wheel is installed, and sucks foreign substances such as dust on the floor along with air through the hose by the suction power of the rotating fan when the motor is driven. And dust is collected in the filter.

However, such a vacuum cleaner is limited to cleaning using only suction power, and in particular, fine dust has a inconvenience in that it is difficult to easily suck due to the influence of static electricity with the bottom surface.

In order to solve this problem, the mop is applied to the inlet separately for home use, or it is equipped with a brush that can be rotated at the inlet for industrial use in a large building, and the cleaning work is performed by spraying and supplying detergent liquid or water to the attached brush. It is a vacuum cleaner.

Among them, one embodiment of a conventional vacuum cleaner to which a rotating brush is applied is Korean Utility Model Publication No. 1995-010070 (designated name: suction port of vacuum cleaner capable of cleaning water) filed by the applicant. In examining the elements, detailed technical configurations and operations will be omitted.

That is, in the vacuum cleaner according to the related art, the cleaner is designed to continuously wash the brush by supplying detergent or water to the brush which is rotated along the periphery of the bottom of the suction inlet body of the cleaner in an elliptical shape. It is designed to rotate by receiving power from the reduction motor built in the main body.

However, in the inlet structure, since the intake port has to absorb dust in a narrow space and clean the vertical wall, if necessary, it is limited by the size and weight of the housing due to the nature of the inlet to be cleaned by hand. As the size of the motor increases in size, it also adversely affects the work purpose. Therefore, it is impossible to increase the driving capacity of the motor in the inlet structure, and accordingly, the rotational power of the brush also fell short of expectations.

In addition, since the suction port is made of an elliptical shape, it is difficult to quickly perform a large area cleaning operation, and there is a problem in that a power loss is relatively large when the brush is rotated.

As a result, the prior art has a problem that it is difficult to maximize the cleaning efficiency through the rotation of the brush to lower the efficiency of the product.

The present invention has been proposed in order to solve the problems of the prior art, the installation of a large-capacity power means for transmitting the rotational power to the brush in the cleaner body which is relatively less constrained by the size and capacity of the suction unit It is to transmit to the side to ensure a stable rotational force of the brush mounted on the bottom of the suction portion, and the purpose of applying an ultrasonic wave to help the brush cleaning.

In addition, another object of the present invention, to prevent secondary pollution due to the detergent liquid sprayed on the brush during the operation of the cleaner and to be able to reuse to show the effect on the environment-friendly aspect.

At this time, the pumping motor 3 is connected to the first connecting hose (7) fresh water in the detergent solution (6) and the second connecting hose (8) for guiding the pumped detergent solution to the suction unit 20, the first One end of the connecting hose 7 is provided with a check valve 9 to prevent backflow of the liquid.

In the figure, reference numeral 4 denotes a detergent liquid preliminary storage box mounted on the cleaner body 1, and 10 denotes a water tank.

And, the configuration of the suction unit 20, as shown in Figure 2 and 3, the outer housing 20a and the lower housing (20b) to form an outer shape, between the axial gears to form a pair of mutually different ( 22a, 22b), one end is connected to the worm gear 22a and the other end extends from the reduction motor 2, the wire cable 11 for transmitting rotational power, and the brush 21 is evenly positioned along the bottom periphery. A circular rotary plate 23, a rotating shaft of the rotary plate 23 is formed on one end of the worm gear 22b and the other end is composed of a shaft 24 to which the fixing member 25 is coupled, the lower housing 20b At the rear side, the suction side has a flow path guide 26 for guiding foreign substances sucked by the suction force from the cleaner body 1, and a protrusion film 27 having a predetermined height and length for separating foreign substances from the rotating brush 21. ), To prevent the brush 21 from rotating inward A support ring 28 is integrally formed.

Referring to FIG. 3, the structure of the suction part 20 will be described in more detail. As shown in an enlarged view, the brush 21 is planted in the assembly 34 coupled to the hinge 33 so as to be rotatable on the bottom of the rotating plate 23. The side of the assembly 34 is provided with a roller 35 for reducing friction with the housing, and the tip of the housing 20a has a ball shape 36 so as to be in line contact with the side roller 35 of the assembly 34. Done.

On the other hand, an ultrasonic generator 29 is installed on the suction side at the rear end of the upper housing 20a to generate an ultrasonic wave of a predetermined frequency for the purpose of vibration transmission and to further separate the foreign matter from the brush 21 in proximity. , And a spray pipe 30 for spraying the detergent liquid guided through the second connection hose 8 to the brush 21 is installed at the bottom thereof, and a plurality of rollers for smoothly flowing on the bottom of the lower housing 20b ( 31) and a rubber 32 were constructed.

The operation of the vacuum cleaner configured as described above will be described below.

First, when a user operates the on / off switch 13 installed in the extension pipe 14, the reduction motor 2 is operated together with the suction motor for performing vacuum suction, and then passes through the flexible hose 12 and the extension pipe 14. The wire cable 11 connected to the worm gear 22a of the suction unit 20 is rotated in one direction. At this time, the worm gear 22a transmits a rotational force to the worm gear 22b which is engaged with both ends being supported by the gear support 22, and the rotation of the shaft 24 in which the worm gear 22b is integrally formed. The rotating plate 23 is rotated together by rotating the brush 21 to perform a cleaning operation.

At this time, the rotating brush 21 receives a rotational force in the outward direction of the rotating plate 23 about the hinge 33 of the assembly 34 by the centrifugal force, the tip of the suction upper housing (20a) is a predetermined slope By limiting the rotation in the form of pressing the assembly 34 is bent to the brush (21) located at the tip of the suction portion of the rotating brush to clean the bottom surface, contact with the tip of the housing forming the ball shape 36 The roller 34 is configured on the side of the combination 34 to reduce the friction between the brushes 21 during the rotation operation of the brush 21.

On the other hand, the height (h) of the outer circumferential surface bent portion of the upper housing (20a) has a shape that gradually decreases from the front end to the rear end. It is gradually released toward the rear end of the suction unit 20, so that the brush 21 is substantially horizontal with the bottom surface due to the rotational centrifugal force at the rear end of the suction unit when the cleaner is driven.

That is, as shown in Fig. 3, 4a or 4b, the rotating brush 21 is to perform the water cleaning of the bottom surface at the tip of the inlet in the state in which the detergent liquid is injected through the injection pipe 30 In addition, the brush 21 in which the foreign matter is adsorbed at the front end is in contact with a plurality of protruding membranes 27 installed in the air inlet flow path while the angle thereof becomes horizontal as the rear end is rotated.

At this time, since the injection pipe 30 is installed just before the brush 21 is in contact with the protruding film 27, the detergent liquid is sprayed here, and then the brush 21 is contacted with the protruding film 27. As the foreign matter adhered together with the detergent liquid is collected into the cleaner body 1 by the suction force.

In addition, an ultrasonic generator 29 for generating ultrasonic waves in a predetermined frequency band is installed at an upper end of the suction channel, so that the effect of separating foreign substances from the brush 21 can be further improved due to the vibration of the ultrasonic waves.

In addition, the brush 21 from which the foreign matter is removed is to perform the cleaning process as described above while the continuous rotation is made.

On the other hand, when looking at the detergent solution supply process to the injection pipe 30 by the pumping motor (3) mounted on the cleaner body (1), the pumping motor by the user's operation of the switch 13 when cleaning the water required by vacuum suction When 3 is operated, the detergent liquid stored at the bottom of the cleaner body 1 is pumped by the first connection hose 7 and supplied to the injection pipe 30 through the second connection hose 8, and the first connection hose. Detergent liquid is prevented from flowing backward by the check valve 9 mounted at the end of (7) so that it flows in only one direction. In addition, the liquid (detergent) that is sucked into the vacuum cleaner body 1 through the flexible hose 12 from the suction unit 20 together with the foreign matter falls back to the lower portion, and the foreign matter is filtered out of the filter net 5 again. Recycling is possible through the above cycle. If the detergent solution stored in the cleaner body 1 is contaminated while the detergent solution is circulated for a certain period of time, the connection part 7 'installed in the middle of the first connection hose 7 is separated, and then the preliminary detergent solution is stored. When connected to the main pit 10 of the storage box (4) it is possible to non-circulating water cleaning when the pump motor (3) operation, the preliminary storage box (4) is located at the top of the pumping motor (3) so that the dye of the reverse flow There is no need for a separate check valve.

5 is a ball shape of the side roller 35 'of the assembly 34 in which the brush 21 is planted in another embodiment of the present invention, the tip side of the upper housing 20a in contact with the ball shape In the case where the section is provided as the flat portion 36 ′, line contact is also made between the rotating plates 23 to minimize component wear and frictional force.

Hereinafter, the characteristics of the vacuum cleaner according to the present invention, which achieves the basic operation as described above, will be described.

That is, the vacuum cleaner is a reduction motor that is the driving force of the brush is installed on the cleaner body to reduce the size and weight of the suction unit and at the same time it is possible to apply a large capacity motor, in the conventional water scavenger cleaning method, cultivation of bacteria or bacteria According to the present invention, the brush cleaning is automatically performed through ultrasonic generation and spraying of the cleaning solution, which is a hotbed, so that sterilization as well as clean and hygienic management are possible, and the inconvenience of having to remove and clean the brush separately is eliminated. Efficiency can also be dramatically increased.

In addition, the sprayed liquid is absorbed back into the cleaner body without splashing or flowing to the outside when cleaning the water using a washing liquid, and the like, and can be cleaned in a public place, especially horizontal and vertical, as well as inclined or curved, and the secondary to the outside. The continuous reuse of sprayed cleaning solutions to prevent contamination can also play a role in environmental protection.

In addition, when spraying only the water to the brush cleaning position in the suction unit to increase the suction power of the air in order to exhibit a constant cleaning power acted as a factor that increases the noise of the motor, in the present invention from the brush to the same element It can be seen that by installing an additional ultrasonic generator to help separate foreign matters, the suction power of the cleaner can be reduced by that much.

In addition, since the brush is formed in a circular plate formed along the periphery of the rotating plate it is possible to minimize the loss of rotational power compared to the conventional elliptical image.
