Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction tool for absorbing water which is connected to an electric vacuum cleaner or the like.

[0002]

2. Description of the Related Art Conventionally, in this type of suction tool for absorbing water, an elastic body formed of rubber or the like in a flat plate shape is arranged in front of and behind an intake port. Hereinafter, this type of suction tool for absorbing water will be described with reference to FIGS. 8 and 9.

As shown in FIGS. 8 and 9, flat plate elastic members 20 and 21 made of rubber or the like are provided on the front and rear sides of the intake port 19 at the bottom of the suction tool body 16 to connect the suction tool body 16. It was connected to an electric vacuum cleaner via a pipe 18, and when used, the front and rear elastic bodies 20, 21 at the lower part of the suction tool body 16 were brought into contact with the floor surface to suck in dirty water such as water through an intake port 19. Reference numeral 17 is a bumper and 22 is a roller.

[0004]

However, in such a conventional suction tool for absorbing water, when the suction tool body 16 is pushed forward, the rear elastic body 2 provided in the lower intake port 19 is provided.
1 bends backward, its tip moves away from the intake port 19, and a step is created between the elastic body 21 and the holding portion until the water sucked along the elastic bodies 20, 21 reaches the intake port 19. However, there is a problem that it becomes a hindrance to the problem of water absorption.

Therefore, the present invention solves such a problem, and an object of the present invention is to provide a suction tool for absorbing water without leaving any residual water.

[0006]

In order to achieve the above object, the present invention has a floor nozzle main body and a floor nozzle pipe, and the floor nozzle has an intake port and operability on the bottom surface of the main body. A floor nozzle roller to make it lighter and front and rear floor nozzle rubbers to improve water absorption performance are provided, and the rear floor nozzle rubber provided on the rear side of the intake port of the floor nozzle body is directed toward the intake port at the part in contact with the floor surface. The slope is provided so that the lower part of the lever protrudes.

Further, the holding position of the rear floor nozzle rubber in the lower part of the suction tool body is configured to be lower than that of the front floor nozzle rubber.

Further, a guide-shaped rubber lip extending from the central portion of the rear floor nozzle rubber to the intake port side of the main body is formed so that the rubber lip is always in contact with the rear wall surface of the intake port.

Further, an intake port is provided at the center of the lower surface of the main body, and a substantially triangular concave portion serving as a ventilation path is formed toward the central portion of the rear floor nozzle rubber, and the concave portion is wider than both ends. Is narrowed and the depth is expanded on the suction port side.

Further, a guide rib that divides the intake port into two parts is provided in the center of the intake port, and the guide rib is held at the intake port by a projecting support.

[0011]

The present invention is constructed as described above,
That is sucked up from the floor, the water toward the intake port side is sucked into a smooth inlet along the rear floor Nozurugomu provided with slope portion. Also, the water sucked into the bottom surface of the floor nozzle
Since the holding position of the rear floor nozzle rubber is formed downward, the wind speed at the intake port increases, and it is possible to suck the wind at a higher speed than before. Further, even if the rear floor nozzle rubber is bent, the guide lip is in contact with the inner surface of the intake port, so that the water on the floor surface can be surely sucked. Further, when the suction tool body comes into contact with the floor surface, the air flow or water flow concentrates on the central portion of the rear floor nozzle rubber of the intake port, effectively acting on the water suction performance. Also, due to the guide rib in the center of the intake port , water collides with the side surface of this guide rib,
Since the water passage to be sucked into the suction port is formed, the improvement of secure and water-absorbing water passage <br/> can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1 and FIG. 2, the floor nozzle body 1 of the suction tool for absorbing water sucks in a bumper 2 on the front and side surfaces of the body, a front floor nozzle rubber 5 made of an elastic body such as rubber, and a rear floor nozzle rubber 6 at the bottom. It has floor nozzle pipes 3 formed before and after the mouth 4 and connected to the extension pipe of the electric vacuum cleaner. Further, as shown in FIG. 3, a sloped portion 7 that is inclined toward the intake port 4 is provided at the tip of the rear floor nozzle rubber 6, and a holding body 8 is formed on the rear floor nozzle rubber 6 so that the intake port 4 An engaging portion 9 to which the holder 8 is attached is formed in the lower part of the.

Further, as shown in FIG. 2, a step portion 10 is formed below the front floor nozzle rubber 5 at the formation position of the rear floor nozzle rubber 6 in the lower portion of the suction tool body 1. Further, as shown in FIG. 4, a guide lip 11 is formed so as to contact the inner wall of the intake port 4 from the vicinity of the center of the rear floor nozzle rubber 6 toward the intake port 4 side. Further, as shown in FIG. 5, the suction port 4,
Also, the recess 13 that can form a vent toward the center of the rear floor nozzle rubber 6 is narrowed from the left and right sides into a substantially triangular shape, and is formed so that the depth expands on the suction port side. Rollers 12 are provided at both ends of the. Further, as shown in FIGS. 6 and 7, a guide rib 15 supported by a projecting support 14 is provided at the center of the intake port 4.

As described above, according to the water suction device of the embodiment of the present invention, the rear floor nozzle rubber 6 of the intake port 4 is provided with the inclined portion 7 on the side of the intake port 4 and the rear floor nozzle rubber 6 is provided in front. It is provided below the partial floor nozzle rubber 5, and further in the center of the intake port 4 and the recess 13 narrowed in a substantially triangular shape toward the center of the intake port 4 from both left and right ends of the guide lip 11 and the bottom of the suction tool body 1. The configured guide ribs 15 can prevent water from remaining on the floor during water absorption, and can form a high wind speed at the intake port and a reliable water absorption path during suction.

[0015]

As is apparent from the above description, according to the present invention, the rear floor nozzle rubber of the suction tool body is provided with a guide lip that is inclined toward the intake port and is in contact with the intake port. By forming the holder for the rear floor nozzle rubber below the front floor nozzle rubber, a water intake passage is secured at the intake port, and the wind speed at the rear of the intake port is increased, making it faster than before. Since the water on the floor is sucked in, it is easy to prevent the phenomenon of water remaining on the floor. Also, the air flow and water flow during cleaning are concentrated in the center of the rear floor nozzle rubber,
Furthermore, the guide ribs on the intake port form a water absorption path,
It is possible to provide a convenient suction tool for absorbing water that can achieve the same effects as described above.
