Description

Cleaning tool

The present invention relates to a cleaning tool for easily separating and removing various types of dirt on the floor by rotating the dirt removal roll, and more particularly, the wear state of the roll itself and the object to be cleaned by the dirt removal roll vertically operated. Regardless of the degree of flatness of the surface of the present invention relates to a cleaning tool to enable a reliable separation and removal of dirt through always maintaining a stable close contact with the cleaning surface.

In general, the traditional method of cleaning the floor has been made by sweeping the dirt off the floor with a broom and then wiping it with a mop. However, such a cleaning method has been very demanding for a lot of physical fatigue due to the hassle of having to perform separate cleaning and mopping, and an uncomfortable posture such as sitting at a waist or a sloppy posture, and also required a lot of cleaning work time.

Therefore, recently, many cleaners having various forms and functions have been developed and used as a solution to the conventional cleaning method. However, in the case of the vacuum cleaner which is currently used a lot, simply removes the dirt adhered to the floor by forcibly removing the remaining dirt on the floor by using the pressure difference between the inside and outside of the cleaner. There is a problem that it is impossible, and the inconvenience of having to mop separately to remove the sticky dirt is caused, a situation that has been developed and used a lot of cleaning tools to stand comfortably in parallel with the vacuum cleaner or separately.

In addition, various types of vacuum cleaners using a rotary brush have been developed in order to remove the dirt adhered to the bottom surface as well as the suction of the dirt. For example, first of all, Korean Utility Model Publication No. 99-13431 There is a "suction structure of the vacuum cleaner with a rotary brush" which installs a rotary brush operated by a separate operation switch inside the suction port to separate and remove foreign substances on the cleaning floor. No. 181851 includes a "rotary brush vacuum cleaner" that cleans various kinds of dust without scattering by driving the rotary brush attached to one side of the suction port of the vacuum cleaner, and the domestic utility model registration No. 245230 is a removable mop. Interposed with a "mop combined vacuum cleaner" that has a structure to enable the function of vacuum cleaning and mop function Also, Korean Utility Model Registration No. 306319 also has a rotary fan installed at the rear of the suction head and a brush roller at the front to easily remove various dirts on the floor or carpet. Suction head ", and in Korean Utility Model Registration No. 305522, the cleaning roller is installed on the front and rear of the main body case and installed to rotate in the opposite direction, sweeping the bottom and collecting the dirt. There is a "motor-driven cleaner" designed to clean the floor and remove contaminants at the same time, saving effort and time spent cleaning the floor.

However, since the rotating brushes and brushes of the prior art mentioned above are all of which cannot be moved up and down, proper brushing force cannot be exhibited when the brushes or brushes themselves are worn by the use or the cleaning surface is irregular. There is a significant structural problem that it is difficult to remove.

Therefore, the present invention was devised in view of the above-mentioned problems, and an object of the present invention is not only to easily clean the indoor or outdoor dirt, but also to install the dirt removal roll so as to be able to flow up and down, or wear or roll of the indoor floor or the like. It is to provide a cleaning tool that enables stable removal of dirt, regardless of the flatness of the cleaning surface.

Another object of the present invention is to provide a cleaning tool that can be improved by removing the dirt by forcibly separating and drawing out the dirt using the dirt removal roll by using the cleaning tool connected to the vacuum cleaner.

Another object of the present invention is to provide a cleaning tool that can be used for various purposes in addition to the cleaning use by making the cleaning tool small and replacing the dirt removal roll with a mop or a polish brush.

Then, both ends of the roll shaft 41 and the drive shaft 25, which are installed to be exposed to the outside of the connecting support piece 42 and the rotating tube 43, respectively, are members for cutting power to the dirt removal roll 30. The driven pulley 45b and the drive pulley 45a which are one of them are provided, respectively, and the belt 46 hangs between them. At this time, the driven and drive pulleys 45a and 45b installed on each of the shafts 41 and 24 are configured to be prevented from being detached by fixing the washers 47 to the outside thereof with bolts 48, respectively. This is only an example and can be achieved by other means of replacement. In addition, the cover 49 is detachably attached to the connecting support piece 42 on which each power transmission member is installed.

On the other hand, referring to Figure 2, by the elastic member 50 in the form of a tension or compression spring or leaf spring interposed between the casing 10 and the connecting support piece 42 of the vertical flow operation 40 It is preferable to comprise so that the dirt removal roll 30 is always pressed down and has a stable close rotational force with a cleaning surface.

In addition, as shown in Figure 2, the dust collecting chamber 12 of the casing 10, it is preferable to more easily configure the disposal of the collected dirt by installing a pull-out drawer 60 for receiving the dirt. The dust collecting chamber 12 is further provided with a connector 16 for connecting the vacuum hose 70 of the vacuum cleaner if necessary.

According to the present invention configured as described above, when the power switch (not shown in the drawing) is turned on as shown in FIG. 2, the small motor 23 of the driving means 20 is operated, and at the same time, the worm gear engaged with the coaxial worm 22 is engaged. 24 rotates. The drive shaft 25 connected to both sides thereof by the rotation of the worm gear 24 is rotated about the support tube 26 of the gearbox 21, and the drive shaft 25 is rotated to both ends thereof by the rotation of the drive shaft 25. The installed pulley 45a is rotated, and the driven pulley 45b of the roll shaft 41 connected by the belt 46 is rotated at the same time.

Accordingly, when the casing 10 is gradually pushed against the cleaning surface by using the handle 14, the casing 10 is stably moved by the wheels 11 and at the same time, the dirt removal roll installed on the roll shaft 41 ( Various dirts remaining on the cleaning surface are easily separated from the cleaning surface while 30) rotates in one direction, and the separated dirt is quickly removed and collected into the dust collecting chamber 12 of the casing 10. At this time, since the roll shaft 30 is in the form of a brush, it is possible to separate and remove non-sticky dirt as well as sticky dirt.

In addition, the dirt removal roll 30 is vertically operated while receiving power as it is transmitted according to the degree of wear of the roll or the flatness of the cleaning surface, which is connected to the support piece provided with the dirt removal roll 30 as shown in FIG. 42 is achieved by pivoting the pivoting body 43 integrally provided therewith with respect to the support tubular body 26 of the drive means 20, wherein the up and down pivoting distance of the dirt removal roll 30 is It is inserted into the rotation operation space 43a of the rotation pipe 43, and is controlled by the rotation control piece 44 fixedly installed in the corresponding support pipe 26. As shown in FIG.

On the other hand, the dirt removal roll 30 continues to rotate despite the up and down flow operation between the up and down flow operation 40, which is a drive shaft 25 for transmitting the power generated from the small motor 23 to the drive pulley 45a. ) Is generated from the small motor 23 because one end portion is penetrated and supported by the inside of the support tube 26 which is integrally connected to the gear box 21 irrespective of the rotating tube 43 of the up and down flow operation 40. The power can be transmitted to the drive pulley 45a, the belt 46, and the driven pulley 45b as it is.

In addition, since the connection support piece 42 is elastically actuated downward by the elastic member 50, the brush which comprises the dirt removal roll 30 is worn out, or the flatness of the cleaning surface is the dirt removal roll 30 which is vertically flow-operated. Even if is different, the proper adhesion can always be exerted.
