A preferred embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing a wet mop having a water injector according to the present invention. FIG. 2 is a combined perspective view of FIG. 1. FIG. 3 is a cross-sectional view of FIG. 2. FIG. 4 is a plan view showing the internal structure of a water tank in the present invention.

As shown in FIGs. 1 and 2, the wet mop according to the present invention includes a wiper 10, a water tank 30 which contains a water injector 20, and on the bottom of which the wiper 10 is attached, a stick 40 which is pivotably fixed on the water tank 30, and a handle 50 fixed to the end of the stick 40, for enabling the water injector 20 to operate. The operation of the wet mop having a water injector according to the present invention will be described in more detail. The handle 50 which has a substantially rectangular shape, includes an operating knob 60 which is pulled upwards therein. As shown in FIG. 3, the operating knob 60 includes a grip portion 61 which is positioned in the inside of the handle 50 and a body portion 62 which is accommodated in the vessel type shank 51 of the handle 50. In particular, a spring 70 is elastically installed around the periphery of the body portion 62 in the operating knob 60. Accordingly, the spring 70 provides a restoring force for returning the grip portion 61 to the original position after the grip portion 61 has been pulled upwards.

The vessel type shank 51 in the handle 50 and the stick 40 are connected to each other. The stick 40 has a hollow vessel shape through which an operating cable 63 the one end of which is fixed to the body portion 62 of the operating knob 60 passes. The operating cable 63 passes through the stick 40 and is connected to a pull-up lever 21 of the water injector 20 which is positioned in the water tank 30. Accordingly, when the operating knob 60 is pulled, the operating cable 63 is pulled and the pull-up level 21 is operated, to resultingly enable the water injector 20 to operate to have water injected outwards through the injection nozzles 31 and 32. The nozzles 31 and 32 are a front injection nozzle 31 for injecting water ahead from the water tank 30 and a bottom injection nozzle 32 for injecting water to the bottom center, respectively. Either or both of the injection nozzles 31 and 32 can selectively operate to inject water through a multi-selector 80 connected to the water injector 20. The water injection mechanism will be described later in more detail with reference to the FIG. 4 water tank inner structure.

A water filling hole 33 for filling water is formed on the upper portion of the water tank 30. The water filling hole 33 is closed with a hole cap 34. When water inside the water tank 30 is short, a user opens the hole cap 34 to then fill water inside the tank 30. Also, a selective rotary switch 90 for enabling the multi-selector 80 to operate is installed on the upper portion of the counter-side of the water tank 30. When the selective rotary switch 90 is rotated, the front injection nozzle 31 and the bottom injection nozzle 32 can be selectively controlled to operate, alone or both. The water tank 30 on which the injection nozzles 31 and 32 are formed, includes a lower vessel 30a in which the water injector 20 and the multi-selector 80 are internally formed, and an upper cover 30b for sealing the lower vessel 30a. The upper cover 30b and the lower vessel 30a are sealingly combined with a number of bolts 100. A sealing member is disposed between the upper cover 30b and the lower vessel 30a, in order to maintain a water sealing. Also, the wiper 10 is detachably attached to the water tank 30, and the stick 40 has a length which conveniences a user to stand and work. FIG. 5 is a plan view showing the upper cover of the water tank shown in

FIG. 4. FIG. 6 is a bottom view of FIG. 4. Referring to FIGs. 4 through 6, the inner structure of the water tank will be described below in detail.

Water is filled in the water tank 30 through the water filling hole 33 formed on the cover 30b. The water injector 20 is provided in the water tank 30. The pull-up lever 21 of the water injector 20 is connected to the operating cable 63. Thus, if the operating knob 60 is pulled by a user, the pull-up lever 21 is pulled up through the operating cable 63. Then, an injection pressure is formed in a body portion 22 of the water injector 20. Accordingly, the water filled in the water tank 30 flows in the water injector 20 through an intake tube 23, to thereby be injected at a predetermined pressure. A flexible pipe 25 is connected to an injection hole 24 of the water injector 20, to thereby supply water to the multi- selector 80. The multi-selector 80 opens or closes communication holes 83 and 84 so that the water can be supplied to the front injection nozzle 31 or the bottom injection nozzle 32, in which a selection piece 82 is advanced to or released from a selection vessel tube 81. That is, a front supply tube 85 connected to the front injection nozzle 31 and the bottom supply tube 86 connected to the bottom injection nozzle 32 are connected to the selection vessel tube 81. In particular, the multi-selector 80 is fixed to a rotary circular piece 92 which rotates according to the select switch 90, in which the selection piece 82 is advanced to or released from the selection vessel tube 81, and an elastic piece 91 is connected to the rear end of the selection piece 82, so that the front communication hole 83 and the bottom communication hole 84 are opened or closed. Therefore, the select switch 90 is rotated to select a front injection mode or a front/bottom injection simultaneous mode. Here, when the front injection mode is selected, the rotary circular piece 92 connected to the select switch rotates in the water tank 30 according to rotation of the select switch 90, to push the elastic piece 91. Accordingly, the selection piece 82 advances in the selection vessel tube 81 to close the bottom communication hole 84. By doing so, water supplied from the water injector 20 through the front communication hole 83 which is open in the selection vessel tube 81 is injected through the front injection nozzle 31 via a front supply tube 85. Here, when a simultaneous mode is selected, the two communication holes 83 and 84 are both opened, water is injected through the front/bottom injection nozzles 31 and 32. Now, referring to the above drawings, a method of using the wet mop having a water injector will be described below in detail.

First, the wiper 10 should be attached on the bottom of the water tank 30, in order to use the wet mop. Then, a user holds the handle 50 provided in the end of the stick 40 and cleans polluted places while moving. Here, in order to perform a water cleaning by injecting water, a user holds the grip portion 61 of the operating knob 60 located in the handle 50, with fingers and pulls it. Then, the operating cable 63 is pulled and the water injector 20 operates. By doing so, water injected from the water injector 20 at a predetermined pressure passes through the multi-selector 80 and is sprayed via the supply tubes 85 and/or 96 and the front injection nozzle 31 and/or the bottom injection nozzle 32. As described above, while water being sprayed, any polluted places are wiped with the wiper 10, in cleaner ways.

In particular, in order to adjust an amount of injected water, the select switch 90 located at the upper portion of the water tank cover 30b is pivoted. Accordingly, when one of the front mode or the simultaneous mode is selected, water can be selectively injected through the front injection nozzle 31 or the front/bottom injection nozzles 31 and 32. Also, when water is deficient, the user opens the water filling cap 34 located at the upper portion of the cover 30b, and then supplements water via the water filling hole 33.

INDUSTRIAL APPLICABILITY
