Description

Mop cleaner {wet duster}

The present invention relates to a mop cleaner, and more particularly, to a mop cleaner for wiping a floor in an apartment, a general house, an office, and the like.

Unlike other countries, Korea's housing culture is to live off its shoes and sleep on the floor, so the floor must be kept clean. Typically, most homes use vacuum cleaners to clean the floor. Such a vacuum cleaner may use a vacuum to remove dust or small foreign matters accumulated on the floor. However, the vacuum cleaner can remove dust or foreign matter that is easily separated from the bottom, but dust or oil stuck to the floor, food waste, etc. cannot be removed. As such, dust or oil, food waste, etc., which could not be removed by a vacuum cleaner, had to be removed using a mop.

By the way, when cleaning the floor using a mop did not give a strong force to the mop could not remove the old time stuck on the floor. In addition, in the prone state to hold the mop by hand to clean the floor, so cleaning the mop used to pain in the lower back and arms. In other words, mop cleaning required hard labor, and therefore, the elderly, pregnant women, and those with back pain could not clean the mop. In particular, these days, the spread of large apartments, the difficulty of cleaning the mop has been highlighted.

Based on these problems, many companies are selling and selling a mop cleaner consisting of an elongated handle bar, and a detachable part for attaching and detaching the mop at the bottom of the handle bar.

However, in the case of such a mop cleaner, when the mop is dirty or the moisture absorbed in the mop disappeared because it had to be replaced with a new mop often caused inconvenience. In addition, since the detachable part to which the mop is attached has a large area, the force applied to the mop cleaner is dispersed. That is, the pressure per unit area applied to the floor by the mop was forced to be small, and thus could not effectively remove the bundled time of the floor.

The present invention has been made to solve the above problems, an object of the present invention is to provide a mop cleaner that does not need to replace the mop.

Still another object of the present invention is to provide a mop cleaner that can apply a large force to the floor to effectively remove the bundled dust.

As illustrated in FIG. 10, the nozzle tube 152 is provided with a nozzle 152a facing the mop 160 to be wound by the pressing unit 20. Therefore, the water flowing into the nozzle tube 152 is sprayed to the mop 160 near the pressing unit 20 through the nozzle 152a. A plurality of such nozzles 152a are formed in the width direction. A fitting protrusion 152b is formed in the nozzle 152a to allow the second line L2 to be described later to be coupled thereto. The fitting protrusion 152b is formed with a barb 152b 'so as not to be separated after the second line L2 is fitted.

The water transfer part 153 is installed on the side of the main body 10. The water transfer unit 153 is to pressurize the water supplied from the bucket 151 to the nozzle tube 152, and a predetermined amount of water should be injected each time it is operated. There are various configurations to make this possible. An example of such a configuration can be found in a toy squirt gun. In a toy squirt gun, a certain amount of water is sprayed out of the muzzle each time the trigger is pulled.

In the present embodiment, the water transfer unit 153, the sub-container 154 is connected to the first line (L1) connected to the bucket 151 and the second line (L2) connected to the nozzle tube 152, respectively, A piston 155 installed inside the sub container 154, a handle rod 156 connected to the piston 155 to protrude out of the sub container 154, and the handle rod 156 are connected to the sub container 154. An elastic member 157 that applies an elastic bias to the handle rod 156 in the protruding direction, and a first backflow to allow only the sub-container 154 to flow into the sub-container 154 and not to flow back. A check valve 158 and a second check valve 159 allow the water to flow from the sub-chamber 154 only to the second line L2 and not to flow back.

The sub-container 154 has fitting protrusions 154a and 154b to which the first line L1 and the second line L2 are coupled, and the fitting protrusions 154a and 154b have first and second lines. The barbs 154a 'and 154b' are formed so as not to be separated after each of the L1 and L2 is sandwiched.

Here, the first check valve 158 or the second check valve 159 may be implemented in a variety of structures, the configuration of the first, second check valve 158, 159 is also generalized.

In the present embodiment, the first non-return valve 158 is a flexible member such as a silicon plate or a rubber plate and is attached to one side of the sub container 154 corresponding to the lower portion of the fitting protrusion 154a. Therefore, the water flowing into the first line L1 is naturally introduced into the sub-container 154 through the first non-return valve 158 after passing through the fitting protrusion 154a.
