JPH1043101A - Method for connecting nozzle with connection pipe of vacuum cleaner - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for facilitating connection and disconnection of the nozzle with the connection pipe of a vacuum cleaner. SOLUTION: The connection parts of a nozzle 1 and a connection pipe 5 of the vacuum cleaner are respectively formed into female and male type straight pipes so as to be easily inserted each other, and the strength of the fitting is suitably loose so as to facilitate attachment and detachment. With a supporting point pin 3 as a supporting point, a stopper arm 2 is attached to the sucking port 1 for floor so as not to drop it when the connection pipe is connected. Near the top end of the connection pipe 5, a groove is provided along all the circumference and when this pipe is connected with the sucking port 1 for floor, the hook-shaped top end of the stopper arm 2 is inserted into this groove and keeps the connected state. A spring 4 for return is provided for the stopper arm 2 to keep the state of inserting the connection pipe 5 into the groove.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for connecting a floor suction port 1 and a connecting pipe 5 of a vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, a floor suction port 1 of a suction type vacuum cleaner.
The connection method between the pipe and the connecting pipe 5 is a method in which the pipes are connected to each other by a frictional force between the pipes in a gentle male and female tapered structure. For this reason, considerable effort is required to attach and detach the floor suction port 1 and the connecting pipe 5, and the connection is lacking in reliability.

SUMMARY OF THE INVENTION The present invention relates to a method of connecting a floor suction port 1 and a connecting pipe 5 in order to facilitate attachment and detachment of a floor suction port 1 and a connecting pipe 5 of a vacuum cleaner. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION The floor suction port 1 and the connection pipe are easily detachable from the connection pipe 5 of the suction type vacuum cleaner by operating the stopper arm 2. 5 is characterized by a connection method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described below.

The connecting portion between the floor suction port 1 and the connecting pipe 5 of the illustrated vacuum cleaner is formed as a male and female straight tube so that it can be easily inserted into each other. So moderately loose. In the floor suction port 1,
The stopper arm 2 is attached to the fulcrum pin 3 as a fulcrum so that the stopper arm 2 does not come off when the connecting pipe is connected.

[0007] A groove is provided on the entire circumference near the tip of the connecting pipe 5, and when connected to the floor suction port 1, the hook-shaped tip of the stopper arm 2 enters this groove to maintain the connected state. . Stopper arm 2 is connected pipe 5
A return spring 4 is provided in order to maintain the state of having entered the groove.

If it becomes necessary to remove the floor suction port 1 during the cleaning operation, the stopper arm 2
The end of the hook shape of the stopper arm 2 comes off the groove of the connecting pipe 5 by stepping on the end of the connecting pipe 5, and the floor suction port 1 is separated from the connecting pipe 5.

When the floor suction port 1 is to be reattached, the connection pipe 5 is inserted into the connection portion of the floor suction port 1 by pushing the stopper arm 2 away, and is attached by the action of the return spring 4.

[0010]

According to the present invention, when cleaning a flat wide surface, or in a small place such as a corner of a room or the back of furniture, or when a high degree of vacuum is required for removing hair, etc. By attaching and detaching the suction port 1 and the connecting pipe 5 with one touch, the cleaning operation can be performed efficiently.
