Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a process for removing dust adhered to carpets, etc.
This invention relates to a vacuum cleaner with a bag brush.

Conventional Structure and Problems It has been known that rotating brushes are difficult to use when cleaning carpets, etc.

Hereinafter, referring to page 2, we will explain (7) about the vacuum cleaner with diameter i.

In Fig. 1, reference numeral 1 is a hand-held cooling machine body, and an electric blower 2 is installed inside it. , the extension pipe 4 and the hose 5 are collected in the dust collection chamber 7 in front of the filter 6.

In the vacuum cleaner configured as above, there are two methods to drive the rotating brush in the urine nozzle: a method in which the turbine is rotated by suction force to drive the rotating brush '/'c'L', IJJ; A method is used in which a rotating brush is driven by providing an electrical hole for a rotating planar blade inside the brush.

However, in the method of driving the rotary brush by fully rotating the turbine using the pumping force, the loss of intake air in the turbine is large, so the suction force becomes wide. Furthermore, if an electric press is installed inside the floor nozzle to drive the rotating brush, the floor nozzle becomes large and heavy, making operation 1'1- significantly worse. In addition to the electric blower inside the shallow water tank, an electric motor is required, which increases the cost.

Purpose of the Invention In view of the above-mentioned drawbacks, the present invention has low suction loss, can efficiently drive the rotating brush in the floor nozzle with a single electric motor, and has a power transmission shaft built into the port to reduce the plasticity of the hose. The present invention provides a vacuum cleaner with improved elasticity and a good outer hose 1731.

Structure of the Invention In order to achieve this object, the vacuum cleaner of the present invention operates by driving a rotating brush in a floor nozzle from an electric blower in the vacuum cleaner body through a power transmission shaft built into a hose. The electric blower inside can directly drive the rotating brush inside the floor nozzle. Therefore, since a rotating brush electric motor is not required, the weight is reduced, the operability is improved, and the cost is also reduced. Also, make sure there are no obstacles such as turbines in the air intake path from the floor nozzle to the vacuum cleaner body!
Therefore, intake loss can be reduced. Moreover, since the power transmission shaft is built into the hose in a spiral shape,
There is no need to separately embed a wire or the like in the hose to give it appropriate plasticity and elasticity, and since the power transmission shaft does not come out of the hose, it has a clean appearance and is easy to use.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 shows a vacuum cleaner according to an embodiment of the present invention. In FIG. 2, 8 is a 4'1t'rf extra machine body, and 9 is a floor nozzle.

An electric blower 10 is built into the vacuum cleaner body 8, and a first shaft 12 is supported by a first bearing 13 in parallel with the electric blower shaft 11. The motor side belt 1 is attached to the electric blower shaft 11 and the 11th III pulley 14 attached to the first shaft.
5 is being passed around. One end of the first shaft is connected to a power transmission hose 1 such as a flexible wire from inside the vacuum cleaner main body 8.
The extension tube 7 is housed in a spiral shape, and is further provided along an extension tube 18 and connected to a floor nozzle shaft 19 in the floor nozzle 9 .

A rotary brush 20 is rotatably mounted on a shaft inside the floor nozzle 9, and a rotary brush pulley 21 attached to the rotary brush 20 and a floor nozzle pulley 22 housed in the floor nozzle shaft 19 are connected to the floor nozzle shaft 19. A nozzle belt 23 is passed around.

It's 411" r l Yotsuki body 8 and filter 2 inside.
4 is provided, and a dust collection chamber 25 is configured in front of it. Note that the Ω force transmission shaft 16 is composed of an inner wire 26 and an outer wire 27, as shown in FIG.

The operation of the vacuum cleaner configured as described above will be described below.

The output of the electric blower 10 inside the vacuum cleaner body 8 is electric blower ff.
The power is transmitted from the 1UJ5 shaft 11 to the power transmission shaft 16 from the first shaft 12 via the motor side belt 15 and the first shaft pulley 14. Further, the power transmitted to the power transmission shaft 16 is transmitted from the floor nozzle shaft 19 in the floor nozzle 9 to the rotary bluff 20' via the floor nozzle shaft pulley 22, the floor nozzle belt 23, and the rotary brush pulley 21! L - Drive 1 rotation.

Further, the dust separated from the surface to be cleaned by the rotating brush 20 passes from the floor nozzle 9 to the extension pipe 18 and the hose 17, and by using all the filters 24 in the vacuum cleaner main body 8,
The rotating brush 2o in the floor nozzle 9 located away from the electric j4 wind Vi16 in the vacuum cleaner main body 8 can be used as a rotating part OJ. Therefore, there is a rotating bluff in the floor nozzle 9.
By providing electric motors for 'g and %J, the floor nozzle does not become large and heavy and the operability becomes poor, and there is also a rotating brush drive turbine in the intake path, which reduces intake air loss. Therefore, the rotary brush 2o can be efficiently driven by a floor nozzle with good operability.

Moreover, since the power transmission shaft 16 is built into the hose 17 in a spiral shape, the hose 17 has appropriate plasticity and elasticity, and furthermore, since the power transmission shaft 16 does not protrude outside the hose 17, the appearance is good. Easy to operate.

In this embodiment, the vacuum cleaner body is a handy quive, but the return machine body may have any shape as long as it has a built-in electric blower.

Effects of the Invention As described above, the vacuum cleaner of the present invention has power transmission i1.1.
By providing 1, the rotating bluff in the floor nozzle can be driven from the electric method fld machine in the vacuum cleaner body, so it is possible to drive the rotating bluff in the floor nozzle. 1i/Jvi, or times,
Since there is no need to install a turbine to drive the plate bluff, the rotating brush can be efficiently driven using the light, small and easy-to-operate floor nozzle.Moreover, the power transmission shaft is built into the hose in a spiral shape. This gives the hose appropriate plasticity and elasticity, and since the power transmission shaft does not protrude outside the hose, it has excellent features such as a clean appearance and good operability.
