Description

[Detailed Description of the Invention] This invention relates to a hose connection device for a vacuum cleaner.

Generally, the most common way to use a vacuum cleaner is to connect the suction hose, extension pipe, and suction port body to the vacuum cleaner's suction port in sequence, and then operate the remote control switch installed on the suction hose. This is the type of usage. When cleaning a narrow space that a person can easily enter but is unsuitable for pulling in a vacuum cleaner, or when cleaning a high place that is quite far from the floor, conventionally, multiple extension pipes were added to the suction hose. There is no other way but to clean it by using the remote control switch.In this case, the distance from the end of the extension tube to the remote control switch is long, making it difficult to operate.

This idea was developed in consideration of these points, and it is possible to extend the suction path and perform cleaning at a location far away from the vacuum cleaner. The purpose of this invention is to provide a hose connection device for a vacuum cleaner that can operate a switch.

This idea provides multiple suction hoses equipped with remote control switches, and normally connects one suction hose, extension pipe, and suction port body to the suction port leading to the dust collection part of the vacuum cleaner in sequence. When cleaning an area far away from the vacuum cleaner, extend the suction path by sequentially connecting other suction hoses, extension pipes, and suction port bodies to the grip pipe of the suction hose connected to the suction port. Then, insert the pin terminal of the succeeding suction hose into the pin insertion hole formed in the grip tube of the suction hose on the suction port side and electrically connect it to the fixed contact of the control switch of the suction hose on the suction port side. Sometimes, the pin terminal inserted into the pin insertion hole can automatically prevent the ON operation of the remote control switch of the suction hose on the suction port side, and therefore the control switch of the suction hose on the extension pipe side cannot be operated. The structure is such that cleaning can be done by doing this.

An embodiment of this invention will be explained based on the drawings.
Reference numeral 1 denotes a vacuum cleaner, and a plurality of suction hoses 3 are provided to be connected to a suction port 2 leading to a dust collecting section of the vacuum cleaner 1. A connecting pipe 4 connected to the suction port 2 is fitted to one end of these suction hoses 3,
A grip tube 5 for connecting an extension tube is fitted to the other end. The connecting pipe 4 has a clamp 7 that removably engages with a locking hole 6 formed in the suction port 2 and the suction port 2.
A pin terminal 9 is provided which is connected to a terminal 8 provided inside. Further, the grip tube 5 is provided with a remote control switch 10. The remote control switch 10 includes a fixed contact 12 connected to the pin terminal 9 for each pole via a coil 11 installed inside the suction hose 3, and a movable contact 14 held by a knob 13. Further, a pin insertion hole 15 is formed in the end surface of the grip tube 5, through which a pin terminal 9 of another suction hose 3 is inserted in order to connect it to the fixed contact 12.

The terminal 8 is connected to the secondary side of a transformer relay 16 as shown in FIG. 7, and the primary side of the transformer relay 16 is connected to a power source via a power cord 17. A series circuit between the electric blower 18 and the relay contact 19 of the transformer relay 16 is also connected to the power source via the power cord 17. The transformer relay 16 and the blower 18 are built into the main body of the vacuum cleaner 1.

In such a configuration, the vacuum cleaner 1 may be placed in a place unsuitable for moving the vacuum cleaner 1 around or at a high place.
When cleaning a place away from the
The connecting pipe 4 of another suction hose 3 is fitted into the grip pipe 5 of this suction hose 3, and the extension pipe 20 and the suction port body 21 are sequentially connected to the grip pipe 4 of this suction hose 3 which is farther from the suction port 2. At this time, the pin terminals 9 of the suction hose 3 on the extension pipe 20 side are inserted through the pin insertion holes 15 of the suction hose 3 on the suction port 2 side, and are connected to the fixed contacts 12 for each pole while pushing back the knob 13 in the OFF direction. Ru.
Therefore, when cleaning a place far away from the vacuum cleaner 1, the suction hose 3 close to the suction port body 21
The control switch 10 can be operated to make cleaning easier.

When cleaning by running the vacuum cleaner 1 around, there is no need to use two or more suction hoses 3; instead, one suction hose 3, the extension pipe 20, and the suction port body 21 are connected to the suction port 2 in sequence. Bye.

Note that such a connection means for the suction hose 3 can also be applied to a suction port installed in each room apart from the vacuum cleaner.

Since this invention is configured as described above, by connecting multiple suction hoses, it is possible to extend the suction path and clean areas far away from the vacuum cleaner. The pin terminal of one suction hose can be connected to the fixed contact of the remote control switch of the suction hose closer to the suction port, and the pin terminal inserted into the pin insertion hole can be used to remotely control the suction hose on the suction port side. It is possible to automatically prevent the ON operation of the switch, and therefore, it has the effect of allowing easy cleaning by operating the remote control switch of the suction hose closer to the suction port at hand. .
