JP2009189673A - Suction nozzle of vacuum cleaner - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To improve a cleaning efficiency of a vacuum cleaner achieving quickly and easily interchanging a suction nozzle with another type of suction nozzle, by solving the problem that it takes time and labor to remove a suction nozzle from a suction extension tube to clean a gap of furniture or the like and then assemble the suction nozzle again, for example, when quickly cleaning the gap during floor cleaning. <P>SOLUTION: The suction extension tube connected to a connecting portion of the suction nozzle is protruded through the connecting portion so as to serve as another type of suction nozzle. The suction nozzle used for floor cleaning is moved closer to a vacuum cleaner body along the suction extension tube without being removed from the suction extension tube. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention relates to a suction tool used in a vacuum cleaner.

The suction tool used in the current vacuum cleaner is one in which an intake extension pipe is provided from a handle which is mainly at hand and a suction port is connected.

The suction inlets connected to the intake extension pipes are used separately for flooring, gaps and other uses depending on the cleaning application. The main suction inlets are the floor suction opening and the clearance suction opening. These replacement methods have been improved, but the cleaning scene changes many times. Each replacement is laborious and cumbersome.

Move the suction extension pipe from the connected suction inlet by moving it to the main body of the vacuum cleaner along the suction extension pipe without removing the suction inlet connected to the tip of the intake extension pipe. Project the air intake extension pipe into a different type of inlet.

By simply moving the suction port in use, the intake extension pipe can be used as another type of suction port, which can be used as a clearance suction port and a corner cleaning suction port. No matter how many times the cleaning place and the cleaning scene change, each time the suction port is removed from the intake extension pipe and separated, there is no inconvenience of reassembling, and the operation efficiency can be increased dramatically because the operation can be made agile. This suction tool operates and has the same effect even if the suction port is not for floor use.

The tip of the intake extension pipe is inserted into the intake extension pipe connection port of the suction inlet. In this state, the suction inlet is fixed so that it stops at the tip of the intake extension pipe. In this state, it is used as a suction port. Next, the fixing is released and the suction port is moved toward the main body of the vacuum cleaner along the intake extension pipe. At this time, the intake extension pipe protrudes from the suction port and becomes a different type of suction port.

As shown in FIG. 1, the tip of the intake extension pipe 2 is connected to the connection part 1 a of the intake extension pipe of the suction port 1. At this time, it fixes with the fixing tool 5 provided in the connection part 1a. This is the suction tool. If the fixing member 5 is released and the suction port 1 is moved along the intake extension pipe 2 to the main body of the vacuum cleaner as shown in FIG. 2, the intake extension pipe 2 protrudes from the suction port 1 to become another kind of suction tool. .

3 and 4 show an example of a fixture. By pushing the fixture piece 5a of the fixture 5, the key piece 5b of the fixture 5 is released from the groove of the fixing rail 2a of the intake extension pipe 2, and the suction port 1 is released from the fixation and can move. It can also be fixed near the handle 3 as shown in FIG.

If the suction port 1 is fixed to the intake extension pipe 2 by providing the intake extension pipe 2 with a recess in which the key piece 5b is fitted as shown in FIGS. 5 and 6, the fixing rail 2a is not necessary. Further, the intake extension pipe 2 is not a perfect circle, but can be formed in other shapes.

As shown in FIG. 10, the intake extension pipe 2 can be protruded from the connection portion 1 a of the suction port 1. When the suction port 1 is released and the suction port 1 is moved in the direction of the main body of the vacuum cleaner, the partition lid 6 is pushed by the intake extension pipe 2 and the intake extension pipe 2 protrudes from the suction port 1. Moreover, the partition lid 6 is closed by the spring 7 by returning to the original state.

The suction tool of this vacuum cleaner can also be used by directly connecting the intake extension pipe 2 to the main body 8 of the vacuum cleaner.

The above is an example, and the present invention is not limited to this.

In view of the effect of the invention, it seems obvious that the efficiency of the cleaning work is improved.
