Description

[Detailed description of the invention] This invention relates to a vacuum cleaner in which a remote control switch for the fan motor is installed on a part of the hose connected to the intake port of the vacuum cleaner body. - To operate the OFF switch and touch switch easily and reliably.

The present invention will be described below with reference to embodiments shown in the drawings.

Reference numeral 1 denotes a vacuum cleaner main body incorporating a fan motor and a dust collection filter, and a floor suction port 5 is connected to an air inlet 2 of the main body via a flexible hose 3 and a telescopic extension pipe 4. 6 is the flexible hose 3
A bent pipe is connected to the extension pipe 4 provided at the tip of the fan motor, and a remote control switch 7 for the fan motor is provided at the upper part of the bent pipe.

The remote control switch 7 is connected to the bent pipe 6.
A pair of rectangular fixed contact pieces are arranged and fixed to face each other with an interval in a recess 8 formed on the upper surface, and one end of which is connected to the ends of the steel wires 9, 9 of the flexible hose 3 by soldering, respectively. 10, 10, and an ON/ON switch fixed to the inner surface of a slide cover 13 that slides along the opening 12 of the cover member 11 that covers the recess 8.
It is composed of an elastic movable contact piece 14 for OFF switching and elastic movable contact pieces 15, 15 for touch switch, and between the fixed contact pieces 10, 10 there is a click switch which can be used for both ON and OFF, and which comes into contact with the movable contact piece 14 as appropriate.
A switching insulating protrusion 16 is provided.

Next, the effect will be explained.

First, connect each accessory to the vacuum cleaner body 1, hold the bent tube 6 provided at the tip of the flexible hose 3, and slide the slide cover 13 forward in the state shown in Figure 4A. As shown in Figure B, since the elastic movable contact piece 14 for ON/OFF switching comes into contact with both the fixed contact pieces 10, 10, the movable contact piece 14 causes both the fixed contact pieces 1
0 and 10 can be made conductive, thereby allowing the fan motor to operate continuously. Further, when the slide cover 13 is pulled forward, the movable contact piece 14 rides on the insulating protrusion 16 for ON/OFF switching, which also serves as a click, as shown in FIG. 4A. At this time, the movable contact piece 14 urges the slide cover 13 upward by its elastic force. Therefore, when cleaning is to be carried out in this state, when the slide cover 13 is grasped, the touch switch elastic movable contact piece 15 conducts both the fixed contact pieces 10, 10, allowing arbitrary operation of the fan motor. Figure 5 A and B are other embodiments, ON/OFF
A switching elastic movable contact piece 14 and a touch switch elastic movable contact piece 15 are provided on the inner surface of the slide cover 13' in a substantially V-shape, and a click switch located on a pair of fixed contact pieces 10, 10 serves also as an ON/OFF switch. The insulating projection 16' and the fulcrum projection 17 of the slide cover 13' are provided in the recess 8 of the bent pipe 6. In this case, when the slide cover 13' is gripped in the state shown in FIG. 8, the movable contact piece 15 for the touch switch is attached to both fixed contact pieces 1.
0 and 10, the movable contact piece 15 brings both the fixed contact pieces 10 and 10 into electrical continuity, functioning as a touch switch and allowing arbitrary operation of the fan motor. Furthermore, when the slide cover 13 is pulled toward the front as shown in FIG.
The ON/OFF switching elastic movable contact piece 14 conducts the pair of fixed contact pieces 10, 10, so that the fan motor can be operated continuously.

According to the present invention, as described above, a part of the hose connected to the intake port of the vacuum cleaner body is turned on and off.
Since it is equipped with a sliding remote control switch with OFF and touch switch functions, you can slide it with your thumb while holding it, improving operability and eliminating unnecessary operations during cleaning. can. Furthermore, if the bent pipe is made rotatable,
It is convenient because no excessive force is applied to the hose and it does not get twisted.
