Further, the paper bag 12b is mounted on the storage unit main body 23 as a mounting unit, and the storage unit main body 23 as the mounting unit is vertically detachably stored in the dust collection chamber 13 with the paper bag 12b mounted. Have been. The dust collecting means 12 is composed of a fixing portion 12a formed of a hard material and a paper bag 12b formed of a soft material having ventilation and having a bag shape.
[0019]
Next, a storage section which is a mounting section of the dust collecting means 12 will be described. 2 to 5, the storage unit includes a storage unit main body 23 and a handle unit 24, and the handle unit 24 is pivotable so as to cover an upper opening from a side surface of the storage unit main body 23. The handle 24 is inverted so as to cover the upper opening of the storage unit by the urging force of a spring 25 which is fixed and is provided between the shaft 24a of the handle unit 24 and the storage unit main body 23. are doing.
[0020]
Next, a description will be given of the bag holding member 26 which is a holding member for holding the swelling of the paper bag 12b within a predetermined range from substantially upward when the paper bag 12b is expanded. In FIG. 6, a bag holding member 26, which is a member separate from the dust collecting cover 18, is detachably fixed to the inner surface of the dust collecting cover 18, and a ventilation hole 26 a serving as a ventilation portion is provided on the surface of the bag holding member 26. Have been. The bag holding member 26 may be fixed by nail fitting or screw fixing. Between the inner surface of the dust collecting cover 18 and the bag holding member 26, a passage 27 which is a flow path of the intake air 44 from the electric blower 14 is provided.
[0021]
Next, in FIG. 2, reference numeral 11a denotes a bumper attached to the upper end of the lower cover 11, which is formed with a lip 11b for air tight between the dust collecting lid 18 and the dust collecting chamber 13, and which is connected to the upper end surface of the bumper 11a. The position restricting portion 11c for restricting the rotation of the handle portion 24 in the forward direction is formed integrally so as to substantially coincide with each other. Reference numeral 24a denotes a rotation shaft of the handle portion, which is urged by a spring 25 as an urging means so that the handle portion 24 automatically turns backward. Further, reference numeral 23a is a position restricting portion formed integrally with the storage portion main body 23 and restricting the rearward movement of the handle portion 24. Numeral 12a denotes a fixed portion, which forms the dust collecting means 12 together with the paper bag 12b. Note that a position restricting portion 11c for restricting the rotation of the handle portion 24 in the forward direction is provided on the storage portion main body 23, and a position restricting portion 23a for restricting the movement of the handle portion 24 in the backward direction is provided on the bumper 11a. Is also good.
[0022]
Next, the dust removing device 28 will be described. 7 to 9, a dust removal device 28 is housed in the lower cover 11 on the opposite side of the communication port 20 and on the opposite side of the bottom surface of the dust collection chamber 13 formed by the lower cover 11. Further, a vibration plate 29 for giving a vibration operation is detachably attached to the dust removing device 28 facing the outer surface of the paper bag 12b.
[0023]
The dust removing device 28 is housed in the lower portion of the lower cover 11 below the dust collecting chamber 13 and is fixed by a lid cover 30. A hollow cylindrical arm standing upright from a movable plate 32 extends from a main body case 31 of the dust removing device 28. A protrusion 33 protrudes into the dust collection chamber 13, and a protrusion 34 at a lower portion of the vibration plate 29 having a lattice shape is inserted and fitted to the arm 33. Since the vibration plate 29 is disposed at a position facing the outer surface of the dust collecting means 12 facing the communication port 20 of the partition wall 19, the suction air which passes through the dust collecting means 12 and is sucked from the communication port 20. It has a lattice shape to form a ventilation part so as not to block the air. The arm 33 is fixed to the main body case 31 via a ring-shaped rubber bushing 34.
[0024]
In the main body case 31, a movable plate 32 having a magnet 37 fixed to the distal end thereof, which is disposed in parallel to the electromagnet 35 and the attraction surface of the electromagnet 36, is built in, and is opposite to the magnet 37 of the movable plate 32. One end on the side is fixed to the main body case 31 by a screw 39 via a rubber sleeve 38 so that the movable plate 32 is rotatable. When the switch is turned on by the vibration control circuit and an AC 100 V power is supplied to the electromagnet 35, the movable plate 32 having the magnet 37 fixed at the distal end by the magnetic field generated by the electromagnet 36 has one end fixed with a screw 38 as a fulcrum, and an arm 33. Vibrates in the directions indicated by arrows 40 and 41 at a cycle corresponding to the power supply frequency (50 Hz or 60 Hz) of the AC 100 V power supply while bending the rubber bushing 34 back and forth. The vibration is transmitted to the vibration plate 29 via the arm 33, and the vibration plate 29 also vibrates in the directions of arrows 40 and 41, and vibrates the outer surface of the paper bag 12b to remove dust.
[0025]
The operation of the above configuration is as follows.
[0026]
As shown in FIGS. 1 to 5, the handle portion 24 is moved rearward by a spring 25 serving as an urging means between the storage portion main body 23 in which the dust collection device 12 is stored in the dust collection chamber 13 and the handle portion 24. It is urged to rotate automatically. The handle 24 is rotatable in the front-rear direction. By providing the bumper 11a with the position restricting portion 11c for restricting the rotation of the handle portion 24 in the forward direction while the handle portion 24 is stored in the dust collecting chamber 13, the handle portion 24 is always substantially Since it is located in the vertical direction (substantially upward direction), it is easy to take out the storage section main body 23, and the usability is greatly improved.
[0027]
Further, even if the handle 24 stops halfway due to resistance caused by fine dust or the like entering the rotation shaft 24a of the handle 24, position control is performed when the storage unit main body 23 is stored in the dust collection chamber 13. The handle portion 24 is corrected by the portion 11c and the position regulating portion 23a, and returns to a substantially vertical direction (substantially upward direction). Therefore, the handle portion 24 does not hit the dust collection cover 18 or the like, and the dust collection cover 18 or the handle portion 24 is moved. No damage.
[0028]
Furthermore, even when the urging force of the spring 25 of the handle portion 24 is somewhat weak, when the housing portion main body 23 is stored in the dust collection chamber 13, the handle portion 24 is corrected by the position control portion 11c and the position control portion 23a, Since the handle portion 24 is regulated in a substantially vertical direction (substantially upward direction), the force for rotating the handle portion 24 may be weak and the usability is good.
[0029]
Further, a restricting portion 23a for restricting the rearward rotation of the handle portion 24 is provided on the side surface of the housing portion main body 23. ) Is maintained and the usability is improved.
[0030]
Furthermore, since the position restricting portion 11c is provided integrally with the bumper 11a provided on the side surface of the dust collecting chamber 13, an inexpensive product that does not require separate parts can be provided.
[0031]
Further, the position restricting portion 11c is provided above the center of the rotation shaft 24a of the handle portion 24. When the handle portion 24 is rotated to the front, the handle portion 24 hits the position restricting portion 11c and the position restricting portion 11c Is located above the center of the rotation shaft 24a of the handle 24, the storage unit main body 23 is naturally pulled up by the rotation shaft 24a of the handle 24, and is taken out of the dust collection chamber 13 of the storage unit main body 23. Is easy.
[0032]
Further, the upper surface of the position restricting portion 11c is provided so as to be substantially the same as the upper end surface of the bumper 11a, so that even if dust accumulates on the position restricting portion 11c, it can be easily removed.
[0033]
