1224501 V. Description of the invention (6) The moving tube ′ is composed of the opening 26 of the communication portion 25 communicating with the above-mentioned rotating brush storage chamber 7 and the ventilating ridge with the above-mentioned lower case 3. 27 "27 is a splicing pipe connected in a releasable manner in the above-mentioned revolving pipe 23, and the inhalation freely revolving from the above-mentioned two directions of respiration # Ϊ 路 28, ## The milk communicating with the tube portion 24 is constituted by an exhaust path 29 formed on the outer periphery of the gas path 28. The exhaust tube portions 25 formed on both sides of the exhaust path 29 communicate with each other. It is installed in a freely revolving manner. In addition, when the cleaner body is driven, the suction from the suction head body 5: 6 ^ of dust and sucked air passes through the suction tube portion 24 of the return pipe 23 and the receiver 27 The suction path 28 is sucked into the cleaner body through an extension pipe, a hose, etc., which is not shown. After the corpse, the air filtered by the dust contained in the dust bag of the cleaner body passes through the extension pipe and the hose. The exhaust flow path, the exhaust path 29 of the connection pipe 27, and the exhaust tube section 25 of the return pipe 23 flow through the opening 26 of the return pipe 23 and the ventilation of the suction head body 5. Port 17 is guided to the flow path 14 and the exhaust gas flowing in the flow path 14 flows into the rotary brush through the notch groove 15 of the partition wall 15 Storage chamber 7. Since the notch groove 18 is formed so as to be located at the shaft support portions 8 and 9 corresponding to the rotary brush 10, the exhaust gas flowing from the flow path 14 into the rotary brush storage chamber 7 is prevented from the air inlet 6 The dust in the sucked air adheres to the shaft supports 8 and 9. Because the exhaust system flowing from the flow path 14 to the rotary brush storage chamber 7 is sucking dust,

Description of the invention (7) ◎ The air filtered in the body, so the dust will not adhere to the shaft supports 8 and 9 of the rotary brush 丨 〇, which can prevent vibration during the driving of the rotary brush 丨 〇 Or noise. Therefore, in a still-flow cleaner, the exhaust gas can prevent dust from adhering to the shaft supports 8 and 9 of the rotary brush 10. Compared with the case where outside air prevents dust from adhering to the shaft supports 8, 9, there is no need to install a filter. (; Fi l1: er), etc., can suppress costs. Also, because a part of the exhaust gas flowing in the flow path 14 is discharged from the inlet portion 22 of the splint 21, the dust adhering to the inlet portion 2 2 of the splint 2 丨 can be removed, and the sliding property of the splint 21 is prevented from being lowered. .

Next, a second embodiment will be described with reference to Figs. 5 to 9. In addition, the same parts as those in the first embodiment are marked with the same reference numerals, and descriptions thereof are omitted. 31 is a storage chamber formed by the partition wall behind the suction port 6 of the lower case 3, and a motor for driving the rotary brush 32 is accommodated on one side of the revolving tube 23 of the storage chamber 31. 33. On the other side of the return pipe 23 of the storage chamber 31, when the rotary brush 32 is driven by the motor 33, and the floor suction head 1 leaves the ground, a safety switch for stopping the motor 33 ( switch) (described later).

The 3 4 system is disposed on the rotating brush 3 2 and drives the rotating brush 32 by the pulley 3 4 and the motor 3 3 (b e 11) 3 6. Pulley at one end, a belt between the rotating shaft 35 and the rotating shaft 35, and the pulley 34 constitute a winding line for dividing the motor 3 3 through the partition wall 4 5 shape 4 5 The part forms a partition wall for accommodating the drive part storage chamber 37 of the drive shaft 35, the belt 36, and the drive part.

1224501 V. Description of the invention (8) The opening 3 8 ′ flows into the storage chamber 3 丨 from the vent 丨 7 of the lower case 3 described above, and flows into the drive section storage chamber 37, and is guided into the rotary brush storage chamber 7. 3 9 is a safety switch which is accommodated in the other side of the return pipe 2 3 of the storage room 3 1 'which is a wheel mounting member 41 provided with a wheel 40 that can be freely swung from the bottom surface of the floor suction head 1. The micro switch (mi crosw itch) 42 built into the floor suction head 1 is integrally formed with the rocking shaft 43 of the wheel mounting member 41, and the wheel mounting member 41 is rocked by the wheel 40 contacting the ground. It is configured by closing the operation section 44 of the micro switch 42. When the vacuum cleaner body is driven, the dust and the sucked air from the suction port 6 of the suction head body 5 pass through the suction tube portion 24 of the return pipe 23, and the suction path 28 of the connection pipe 27 through the unillustrated The extension tube, hose, etc. shown are sucked into the cleaner body. After the seventh place, the air filtered by the dust contained in the dust collecting bag of the vacuum cleaner body passes through the exhaust pipe flow path formed by the extension pipe and the hose, and flows through the discharge pipe 29 of the connection pipe 27 and the return pipe 23 The exhaust pipe portion 25 is guided to the storage chamber 3 J through the opening 26 of the return pipe 23 and the air vent 丨 7 of the suction head body 5. The air flowing into the storage room 31 on the side of the storage motor 33 is cooled in the winding section of the electric motor 733, and then flows into the storage section of the driving section through the partition wall 45, and is guided to the rotating brush storage room 7. The deer ridge 1 flows into the storage compartment 3 1 on the side of the safety switch 3 9 to prevent the air from adhering to the safety switch 39 and flowing into the rotary brush storage compartment 7 through the notch 8 of the partition wall 4. Since the notch groove 18 is formed by a process located at the shaft support portion 8 corresponding to the rotary brush 32, the exhaust gas flowing from the storage chamber 3 into the rotary brush storage chamber 7 is formed.

5 1224 ^ 01 Description of the invention (9) = k suction lice = 6 The dust in the air sucked attaches to the shaft support, flows from the opening 38 in the wall 45, and flows into the drive unit storage chamber 37, and flows into the u m7 Exhaust air prevents dust in the air sucked in from the suction port 6 from adhering to the shaft support portion. The exhaust gas flowing from the storage room 31 containing the safety switch 39 into the rotating brush storage room 7 was crying too much because of vacuuming. Check the calendar. . The air filtered by the body so that the dust does not adhere to the king? Off 39 'can prevent erroneous operation', and dust does not adhere to the shaft support portion 8 of the rotary brush 32, and can prevent vibration, voice, etc. from being generated during the driving of the rotary brush 32. -Also, because the storage room 31 containing the motor 33 is stored to 37 by the drive section, the exhaust gas from the IL into the rotating brush storage room 7 is also the air filtered by the cleaner body, and the motor 33 can be cooled to prevent dust from adhering. The belt 36 or the pulley 3 4 ′ can surely drive the rotary brush 32. Therefore, in the still-flow cleaner, the exhaust gas can prevent dust from adhering to the shaft support portions 8 and 9 of the rotating brush 32, and the driving portions such as the belt 36 or the pulley 34, and can prevent the rotating brush 32 from idling, etc. Compared with the case where dust adheres to the shaft support, it is not necessary to install a filter, etc.

this. W In this embodiment, although the drive source of the rotating brush 32 is the motor 33, the rotating brush 32 may be driven by a turbine. As described in item 丨 of the patent application scope of the present invention, in a still-flow vacuum cleaner, dust is prevented from adhering to the shaft support of the rotary brush through exhaust gas from the return pipe, and vibration or noise during use can be prevented Compared with the case where outside air prevents dust from adhering to the shaft support portion, it is not necessary to arrange a filter or the like, and the cost can be reduced.
