Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a vacuum cleaner that uses a filter such as a disposable paper bag, which can be discarded together with collected dust.

Disposable filters such as paper bags are weaker than filters that can be recycled to remove dust and can be used repeatedly.

If the disposable filter gets damaged during dust collection or gets torn when taking it out of the filter storage compartment, please be careful when carrying the disposable filter.
It is unsanitary because of the dust.

Unfortunately, I have to carry the entire vacuum cleaner case. Even if the vacuum cleaner has a structure in which the main case can be split in the middle, you still have to carry the dust collection main case, which houses the disposable filter, with you. It is difficult to handle because it is heavy.

Further, the main body case or the dust collecting side main case of the vacuum cleaner is formed with a disposable filter storage portion and is also provided with a coarse filter and a fine filter that can be used repeatedly. If you do not have a spare disposable filter, use a method of collecting dust directly into the disposable filter housing without using a disposable filter. When disposing of garbage, it is necessary to carry the main body case and the dust collection side main case.

It is an object of the present invention to provide a vacuum cleaner that can cope with such problems in handling and that can be easily disposed of without sacrificing the advantages of a disposable filter.

The present invention provides a dust collector storage section in the main body case or the L dust collection side main case, and provides a dust collection case that is stored in the dust collector storage section and can be taken out and put in freely. A disposable first fine filter formed of a paper bag or the like is formed in the dust collector storage part and is stored in the dust collection case so as to be freely put in and taken out. A second fine filter is formed in the back of the dust collection case facing the dust removal device, and a coarse filter is formed between the first fine filter and the 21st iA filter. It is characterized by the intervention.

When the garbage is full, the user takes out the disposable first fine filter from the dust collection case, carries it around, and throws it away. If the disposable first fine filter is damaged during dust collection or is about to break when taken out from the dust collection case, do not forcefully pull out the disposable first fine filter.

Pull out the dust collection case from the dust collector storage compartment with the filter still inside. Carry the dust collection case as it is and throw away the garbage inside the dust collection case along with the disposable first fine filter into a trash can. Since there is no need to take the trouble of carrying the damaged disposable first fine filter naked, it is possible to dispose of the garbage in a sanitary manner.

Although the dust collection case has a second fine filter and a coarse filter, it is compact enough to accommodate a disposable first fine filter.

Since it is smaller and lighter in weight than the main case of a vacuum cleaner or the main case on the dust collection side, the dust collection case is easy to carry and can be easily attached and removed. .

It is desirable to thoroughly clean the inside of the dust collection case, especially the second fine filter and coarse filter shaft. Since the dust collection case is easy to handle as described above, it can be said to have excellent practical effects that allow frequent cleaning.

Embodiments of the present invention will be described below with reference to the drawings.

The main body case 1 of the vacuum cleaner shown in FIG. 1 is vertically divided into two main body case members 2a and 2 as shown in FIG.
It is composed of b.

As shown in Fig. 1, the joined body case members 2m and 2b are connected to three screws provided at the handle portion 3 (as clearly shown in Fig. 2) and the three screws provided at the top and bottom of the front side. It is tightened with two screws placed above and below, two screws placed above and below the rear side, and one screw placed in the center of the bottom.

An electric blower storage chamber 4 is formed inside the center and rear sides of the main body case members 2a, 2b. An exhaust chamber 5 is formed on the rear side adjacent to the electric blower storage chamber 4. A cord winding device storage chamber 6 is formed on the lower side adjacent to the electric blower storage chamber 4.

Each storage chamber 4, 5.6 is divided by a partition wall 7, 8.9.

An electric blower 10 is installed in the electric blower storage chamber 4, a urethane sound absorbing plate 11 is installed in the exhaust chamber 5, and a cord winding device 12 is installed in the cord winding device storage chamber 6. These attachments are performed by joining the main body case members 2m and 2b together.

A fan casing portion 13 of the electric blower 10 is supported on the front side of the electric blower storage chamber 4 via a front vibration isolating rubber 14. The rear part of the electric blower 10 is supported in a support hole 16 of the partition wall 9 via a rear vibration isolating rubber 15.

A cord 18 is wound around a reel body 17 of the cord winding device 12. Gear teeth are formed on the outer periphery of the lower plate 19 of the reel body 17. A brake ring 20 is formed on the lower side of the lower plate 19.

A dust removal device 21 is provided on the front side of the electric blower 10, that is, approximately at the center of the main body case 1.

FIG. 4 shows this dust removal device 21 in sections. The dust removal devices 21 are collectively provided on a support substrate 22 to form one unit.

The dust removal device 21 will be described in detail based on FIGS. 1 and 4. The dust removal gear 23 is attached to the center of the support substrate 22. The dust removal gear 23 has a plurality of ventilation windows 24 formed therein. Dust-filtered air flows through the ventilation window 24 to the electric blower 10 side. Teeth are formed on the outer periphery of the dust removal gear 23.

A cylindrical attachment portion 25 is formed on the back surface of the dust removal gear 23. The cylindrical attachment portion 25 is fitted and attached to a cylindrical support portion 26 formed at the center of the support substrate 22. A locking pawl 27 is provided on the outer periphery of the tip of the cylindrical attachment portion 25 . This locking pawl 27 engages with the rear end of the cylindrical support portion 26 to prevent the dust removal gear 23 from being removed. Since the dust removal gear 23 is made of plastic, the locking pawl 27 bends inward when the cylindrical attachment part 25 is fitted into the cylindrical support part 26.

Fitting is done easily. The attached dust removal gear 23 is rotatable on the support substrate 22. A plurality of ventilation holes 28 are formed in the support substrate 22 at positions facing the ventilation windows 24 of the dust removal gear 23. The dust-filtered air flows through the ventilation hole 28 to the electric blower 10 side.

A dust remover 29 is attached to the center of the surface of the dust removal gear 230 with a screw 30.

A connecting gear 31 and a face gear 3 are provided on the lower side of the support board 22.
2 is rotatably attached. That is, by inserting the cylindrical portion 34 formed at the center of the face gear 32 into the gear support cylindrical hole 33 and inserting the mounting foot 35 of the connecting gear 31 into the cylindrical portion 34, The claws engage with the rear end surface of the cylindrical portion 34. In this way, the connecting gear 31 and the face gear 32 are coupled.

The inside of the cylindrical portion 34 is a square hole. Since the mounting foot 35 is flat, the rotation of the face gear 32 is transmitted to the connecting gear 31.

The connecting gear 31 is engaged with the teeth of the dust removal gear 23. The rotation of the face gear 32 is transmitted to the dust removal gear via the connection gear 31.

A dust removal cam 36 is rotatably mounted on the upper side of the support substrate 22. That is, the shaft 38 of the dust removal cam 36 is rotatably supported by the cam support cylinder portion 37 . A support tube that rotatably supports the coupling gear 39 is formed concentrically with the cam support tube 37 on the back side of the cam support tube 37 . A coupling 4° spring 41 and a connecting shaft 42 are attached to the inside of the coupling gear 39.

When the connecting shaft 42 and the dust removal cam 36 are tightened with the screw 43, the coupling gear 39, the coupling 4o, and the spring 41 are also attached together.

The coupling gear 39 and the coupling 4o are connected in one rotation but not connected in the other rotation. When the coupling gear 39 rotates in a direction in which rotation is not transmitted, the coupling 4o slides on the connecting shaft 42 against the spring 41 and escapes. Due to this escape, rotation of one side of the coupling gear 39 is not transmitted to the coupling 40.

The coupling 40 and the shaft 42 are engaged in any direction of rotation. When the coupling 4o is rotated nine times by the coupling gear 39, the dust removal cam 36 rotates via the connecting shaft 42. When the coupling gear 39 rotates in a direction in which the coupling 40 is not rotated, the dust removal cam 36 does not rotate, and only the coupling gear 39 rotates idly.

The coupling gear 39 engages with the teeth of the dust removal gear 23. The rotation of the dust removal gear 23 is transmitted to the coupling gear 39. However, as described above, the coupling gear 39 idles during one rotation, so the dust remover 29 always rotates when the dust removal gear 23 rotates, but the dust removal cam 36 rotates only in one direction.

The dust removal device 21 has the above-described configuration, and is attached to the main body case 1 in the following manner.

As shown in FIGS. 1 and 2, the main body case members 1a and lb include a front partition wall 44 of the cord winding device storage chamber 6.
is provided. On the front side of the front partition wall 44, a vertical reinforcing lip 45 is formed at a distance from top to bottom on the inner wall surface of the main body case members 1a, lb. In addition, the main body case la,
A lateral reinforcing lip '46 is formed on the inner wall surface of lb.

A notch 47 is formed in this lateral reinforcing lip 46.

Further, a receiving hole 48 is formed in the front partition wall 44.

A dust removal device 21 is installed between the front partition wall 44 and the vertical reinforcing lip 45.
The dust removal device 21 is attached to the main body case 1 by fitting the lower part of the support board 22 and the side part of the support board 22 into the notch 47. The receiver has a face gear 32 in the hole 48.
The outer periphery of the gear support cylinder hole 33 supporting the gear is supported.

The above attachment is performed when the main body cases la and lb are tied together. Since it is attached in this manner, parts such as screws are not required for attaching the dust removal device 21.

When the dust removal device 21 is attached to the main body case 1, the face gear 32 engages with the gear of the reel body 17.

Since the dust removal device 21 is connected to the cord winding device 12,
The rotation of the reel body 170 is transmitted to the dust removal device 21. The dust remover 29 together with the dust removal gear 23 rotates whenever the reel body 17 rotates, but the dust removal cam 36 rotates only when the cord 18 is pulled out. In order to reduce the load on the winding spring provided in the cord winding device 12, the dust removal cam 36 is prevented from rotating when the cord 18 is wound.

A dust collector housing section 49 is provided inside the main body case 1 located in front of the dust remover 21.

The front part of this dust collector housing section 49, that is, the main body case 1
A loading/unloading opening 51 through which the dust collection case 50 is inserted or removed is formed on the front side.

There is an annular protrusion 52 on the front edge of the loading/unloading opening 510.
is formed. The height of the protrusion 52 is 2 sm, and the width is 5 sm.
■It is. Further, the loading/unloading opening 51 as a whole is inclined so that the upper side thereof is tilted toward the rear side.

The dust collection case 50 is approximately box-shaped as shown in FIG.

Inside these, a disposable first fine filter 53 formed of a paper bag is removable: Monthrj+S.

A filter loading/unloading opening 54 through which a disposable first fine filter 53 is inserted and taken out is formed on the front side of the dust collection case 50, and a second fine filter 55 is formed on the rear side.

The second fine filter 55 is formed by bending a filter material such as nonwoven fabric or cloth into a wave shape. Since the dust collection case 50 is made of synthetic resin, it is integrally formed by placing the second fine filter 55 in a mold when manufacturing the dust collection case 50. The second fine filter 55 is a disposable first fine filter 53.
Unlike other materials, it has sufficient hardness and shape retention.

The size of the dust collection case 50 is 18 cm in width and 21 cm in height.
crn1 depth is 15 including the second fine filter 55
It is cW&.

The second fine filter 55 has a wave height of 2 tM and is formed to run vertically. Seven peaks are formed symmetrically on the back surface of the dust collection case 50. The center is the second
Since the fine filter 55 is not formed, there is no air permeability. The width of the back of this central part is 25 m, and a dust removal striking rod 56 is provided here. The lower end of the dust removal striking rod 56 is fixed to a support base 57 with a screw 58. Since the upper side is not fixed, the upper side of the striking rod 56 is free.

The dust removal striking rod 56 is recessed from the top of the second fine filter 55. The dimension between the top and the end face of the striking rod 56 is 1
It is cIn.

A hollow receiving protrusion 59 is integrally formed in the central rear portion of the dust collection case 50. The receiving protrusion 59 is provided above the striking rod 56. The striking rod 56 is configured to hit the receiving protrusion 59 when the striking rod 56 swings. The receiving protrusion 59 opens inward of the dust collection case 50, but is closed on the outside.

A lip 60 is formed on the inner wall surface of the dust collection case 50 and extends from the front side toward the back side. A large number of these lips 60 are provided. The height of the lip 60 is 3cm.

This lip 60 is designed to allow good ventilation between the outer surface of the disposable first fine filter 53 and the inner wall surface of the dust collecting case 50. The reason why the lip 60 is formed so as to extend in the front-rear direction is to take into consideration both mold cutting of the dust collection case 50 and ensuring ventilation.

The inlet/outlet opening 51 of the dust collection case 50 has an annular flange 61 at the mouth edge. The collar portion 61 extends to the outer periphery and is integrally formed with a deep portion 61' projecting forward on the outer periphery.

A dust collection case airtight backing 62 is attached to the insertion/removal opening 51 of the dust collection case 50. This dust collection case airtight backing 62 is made of an elastic material such as rubber.

There is a mounting groove in the center of the dust collection case airtight backing 62.
A thin lip 63 extending to the outer periphery is provided on the front surface, and a collar portion 64 extending inward is provided on the rear surface. and brim 6
A rear portion 65 that protrudes rearward is provided on the outer peripheral portion of the rear surface of 4.

The dust collecting case airtight backing 62 is attached to the dust collecting case 50 by fitting the flange 61 and the inner part 61' of the dust collecting case 50 into its mounting groove. The opening 51 of the dust collection case 50 is surrounded by a dust collection case airtight backing 62 at its mouth.

When the dust collection case 50 is inserted into the dust collector storage section 49 and attached, the protrusion 52 on the dust collector storage section 49 side
The collar portion 64 of the dust collecting case airtight backing 62 and the inner part 65 of the dust collecting case airtight backing 62 abut on the outer periphery of the protruding portion 52, which is set back one step. This contact ensures airtightness between the front outer periphery of the dust collection case 50 and the dust collection device storage section 49.

A removable coarse filter 66 is attached to the deep inside of the dust collection case 50.

As shown in FIGS. 1 and 3, this coarse filter 66 has a frame 67 and a net 68 made of nylon, polyethylene, etc. that is integrally stretched thereon.

A tuning fork-shaped vibration transmission body 69 is integrally formed on the net 68. A vibration receiver boss 70 is formed on the upper central rear surface of the vibration transmitter 69. A vertical rib 71 is formed on the front side of the vibration receiver boss 70 . Also, the receiver boss 7
A vertical support bone 72 is formed that extends downward from 0. A disk 73 is formed approximately at the center of the longitudinal spine 72. An annular inner part 74 is formed on the back surface of the frame 67.

The coarse filter 66 is inserted into the inside of the dust collection case 5o from the filter insertion/extraction opening 54 of the dust collection case 50,
Set it in the back. The coarse filter 66 is inserted using the vertical lip 71.

The set coarse filter 66 has the end face of the inner part 74 entirely in contact with the inner face of the dust collection case 50 . Then, inside the dust collection case 50, the second fine filter 55 is placed within the inner part 74.

The vibration receiver boss 70 connects the coarse filter 66 to the dust collection case 5.
When set to 0, it fits into the hole of the receiver protrusion 59.

When the dust collection case 50 equipped with the coarse filter 66 is set in the dust collection device storage section 49, it is placed in the state shown in FIG. The dust collection case 50 is set so that the dust removal cam 36 is joined to the side surface of the dust removal striking rod 56 and the dust removal element 29 is located in the valley on the back side of the second fine filter 55.

The head of the dust remover 290 is inserted several times into the valley on the back side of the second fine filter 55, so even if the dust remover 29 rotates while hitting the back of the second fine filter 55, it will not reach the dust removal striking rod 56. is not true.

As the dust remover rotates 290 times, the dust removal cam 36 also rotates. The dust removal cam 36 rotates only when the cord 18 of the cord winding device 12 is pulled out, but due to the rotation of the dust removal cam 36, the dust removal striking rod 56 bends against its own elasticity. When the peak of the dust removal cam 36 comes off the dust removal striking rod 56, the dust removal striking rod 56 instantly returns to its original position due to its elasticity. At this time,
The dust removal striking rod 56 strongly strikes the receiver protrusion 59. The receiver protrusion 59 vibrates strongly, causing the vibration transmitter 69 to vibrate via the receiver boss 7o.

The net 68Fi vibrates together with the vibration transmission body 69, vibrates the disposable first fine filter 53 housed in the dust collection case 50, and removes dust from the first fine filter 53. At the same time, the second fine filter 55 is also vibrated by the dust remover 29, so that the second fine filter 55 is also cleaned of dust.

An inner lid body 75 that can be opened and closed is attached to the front side of the dust collection case 50. When the inner lid body 75 is closed, the lower side of the filter insertion/extraction opening 54 of the dust collection case 50, which is about half of the total opening area, is closed. The inner lid body 75 is rotatable because its lower side is supported by a support shaft, and can be opened by tilting it toward the front.

When the inner lid body 75 is opened with the dust collection case 50 removed from the dust collector housing 49, the top side of the inner lid body 75 is flush with the bottom line of the dust collection case 50, or is slightly wider than the bottom line. The inner lid body 75 is made to stop at a certain point. This makes it easy to attach and detach the disposable first fine filter 53.

In particular, if the tip of the inner lid body 75 is configured to stop at a point slightly lower than the bottom line, it is convenient for the following usage method.

That is, when the dust collection case 50 is placed horizontally with the second fine filter 55 facing down, the opened inner lid body 75 stops slightly beyond the vertical position. Since it is stable in this state, it is easy to pull out the disposable first fine filter 53.

Further, if the inner lid body 75 is opened any further, it will come into contact with the lip 63 of the airtight backing 62 of the dust collecting case, and the lip 63 will be pinched outward. Since the dust collection case airtight backing 62 is attached using elasticity, there is a risk that it may come off by gouging. The opening degree of the inner lid body 75 as described above is sufficient for drawing out the disposable first fine filter 53.

Even if it is opened further, the disposable first fine filter 53
The opening angle of the inner lid body 75 is preferably set to the above value because it does not improve the ability to draw out the dust collection case and, on the contrary, causes problems with the airtight backing 62 of the dust collection case.

The reason why the dust collection case 50 is placed comfortably with the second fine filter 55 facing down is because the second fine filter 55
This is because the top of the back surface of the filter 5 is flat as a whole, the second fine filter 55 itself is made of a relatively hard shape-retaining material, and there is nothing protruding from the top of the back surface. .

The reason why the dust removal striking rod 56 and the receiver protrusion 59 are lowered by about 1 cm from the top of the rear surface of the second fine filter 55 is to take into consideration the placement of the dust collection case 5o as described above. It is straightforward to view this as a configuration resulting from the relationship in which child 29 is provided.

That is, placing the excitation source for the coarse filter 66 inside the dust collection case 5o requires a complicated structure. If provided on the outside, it is best to provide the dust removal striking rod 56 between the second fine filters 55.

However, since the second fine filter 55 itself must also be cleaned with the rotary dust remover 29, the dust removal striking rod 56 must be installed at the position described above so as not to interfere with the rotation of the dust remover 29. yeah.

Further, as a result, the dust removal striking rod 56 no longer protrudes from the top of the rear surface of the second fine filter 55, so that the length of the main body case 1 is reduced accordingly.

When the inner lid body 75 is closed, the front surface thereof and the lip 63 of the airtight backing 62 of the dust collection case are depressed into the inside of the dust collection case 50. This will be discussed in detail later.

A large recess 76 is formed in the front surface of the inner lid body 75. The recessed portion 76 extends toward the tip side of the inner lid body 75. Recess 7
Step portions 77 are provided on the left and right sides of the distal end side of 6. Recess 76
A recess 78 is provided on the lower side. On the other hand, a mounting bin 79 is formed in the upper center of the filter loading/unloading lever portion 54 of the dust collection case 5o.

The configuration of the dust collection case 50 is as described above.

The total weight is approximately 400g. Since the size is the same as mentioned above, it is easy to handle.

The disposable first fine filter 53 is attached to the inner lid body 76 and the attachment bottle 79, but before explaining this attachment, the disposable first fine filter 53 will be described in detail.

The disposable first fine filter 53 inflates as shown in FIG. 1 when dust is collected, but is folded up as shown in FIG. 3 before use.

The disposable first fine filter 53 is made of thin, soft paper or the like. Because they are made of soft material, folded items swell due to dust absorption. A mounting plate 80 is attached to the disposable first fine filter 53. A suction port 81 communicating with the fine filter 53 is formed in the center of the mounting plate 80 . A mounting hole 82 is formed on the upper side of the mounting plate 80, and a lid 83 is formed on the lower side. A perforation is formed in the connecting portion of the lid 83 for folding. The mounting plate 80 is made of thick, hard paper and has perforations.

When the disposable first fine filter 53 is attached to the dust collection case 50, it becomes as shown in FIG. Since this is before dust collection,
Actually, the fine filter 53 is not inflated.

As shown in FIG. 6, both lower ends of the mounting plate 80 fit into the stepped portions 77. For installation, the hole 82 fits into the mounting pin 79. Lid 8
3 fits into the recess 76. Since the mounting holes 82 and the stepped portions 77 are formed somewhat thick, the mounting plate 80 can move up and down and left and right. After dust collection, the suction port 81 is closed with the lid 83. Since there is a recess 78 when raising this lid 83, the lid 83
Since it is easy to put a finger on the lid 83, it is easy to close the lid 83.

When attaching the disposable first fine filter 53, the inner lid body 76 is closed first. The inner lid body 76 remains closed because the filter opening 54 of the dust collection case 50 is slanted.

The mounting plate 80 of the disposable first fine filter 53 can be set without holding down the inner lid body 76 by hand.

Since the inner lid body 76 does not open naturally even after setting, it is easy to handle.

An outer cover 84 that can be opened and closed is provided on the front side of the main body case 1, as shown in FIGS. 1, 5, and 7. Outer lid 8
4 is rotatably supported by a shaft at the lower front side of the main body case 1.

A front cover 85 is attached to the front surface of the outer lid 84, and an inner cover 86 is attached to the inner side. The front cover 85 has a suction port 87 to which a suction hose (not shown) is detachably attached.
is provided. The inner cover 86 has an outflow guide port 88.
is provided. The tip of the suction port 87 is attached to the root of the outflow guide port 88 via a backing 89. A check valve 89' is integrally formed in the backing 89. A suction packing 90 is provided around the outer periphery of the outflow guide port 88.

A clamp 91 is attached to the upper side of the outer lid 84. The clamp 91 is provided with a spring 92 for biasing the engagement.

On the other hand, a clamp locking portion 93 is provided at the upper front side of the main body case 1. When the outer cover 84 is closed, the claw 91 engages with the two-pump locking portion 93, and the outer cover 84 does not open. When the clamp 91 is operated to remove the claw from the clamp locking portion 93, the outer cover 84 can be opened.

When the outer lid 84 is closed, the outflow guide port 88 is inserted into the suction port 81 provided in the mounting plate 82 of the disposable first fine filter 53. The suction backing 90 contacts the mounting plate 82, and the outer circumferential side of the inner cover 86 contacts the lip 63 of the airtight backing 62 of the dust collection case.

When the outer lid 84 is closed, the outflow guide port 88 is smoothly inserted into the suction port 81 even if there are some dimensional variations. This is because the mounting plate 82 is attached to the front side of the dust collection case 50 so that it can move up and down and left and right to some extent as described above.

Since the lip 63 of the dust collection case airtight backing 62 contacts the outer periphery of the inner cover 86, the airtightness between the dust collection case 50 and the outer lid 84 is maintained. Outside air does not flow in from the outer periphery of the inner cover 86.

The inner lid body 76 and the mounting plate 82 of the disposable first fine filter 53 are placed so that they are slightly inside the dust collection case 50 than the outer peripheral edge of the lip 63 provided on the airtight backing 62 of the dust collection case. Therefore, the contact between the lip 63 and the inner cover 86 is not prevented.

Since the lip 63 is pressed by the inner cover 86, the flange portion 61 and the machine portion 65 provided on the dust collection case airtight backing 62 are pressed against the front side of the dust collection device housing portion 49.

The airtightness between the dust collection case 5o and the dust collection device storage section 49 is improved accordingly.

The dust collection case airtight backing 62 has a simple structure because the above-mentioned two locations are sealed with one airtight member. If this is done using two airtight parts, it becomes complicated because the airtightness between the airtight member and the dust collection case must also be considered.

A filter storage chamber 94 is formed in the main body case 1 below the nozzle part 3. The filter storage chamber 94 opens at the rear of the main body case 1.

A lid 95 that can be opened and closed is attached to this opening. The main body case 1 is formed with a notch 95' on which a finger can be hung. In the filter storage chamber 94, the metal part of the disposable first fine filter 53 is folded and stored.

The filter storage chamber 94 is approximately 2/3 of the total length of the main body case 1.
There is depth. As shown in FIG. 3, the folded disposable first fine filter 53 can be stored as is.
You don't have to forcefully fold it to make it smaller and store it. It is easy to put in and take out. In addition, this filter storage chamber 94 is partitioned by the top plate 96 of the electric blower storage chamber 4 and the top plate 97 of the dust collector storage section 490.
Fine dust, etc. in the suction airflow does not circulate.

The embodiments of the present invention have been described above mainly from the structural aspect. Next, embodiments of the present invention will be described from the viewpoint of operation.

Nine dust collection cases 5 equipped with disposable first fine filters 53
0 is set in the dust collector housing 49 and the electric blower 10 is operated, air containing dust flows through the suction hose and flows into the disposable first fine filter 53.

Upon entering the first fine filter 53, the airflow opens a rubber check valve 89'. The check valve 89' is connected to the outflow guide port 88.
Since it is held down by the air, it opens downward, so the airflow is bent diagonally downward. Since the speed of the heavy dust is suppressed when bending, the impact force colliding with the disposable first fine filter 53 is weakened.

Since the fine filter 53 is made of a relatively weak material such as paper, suppressing the impact force is more effective in preventing damage to the fine filter 53.

Most of the dust, including fine dust, is filtered out from the airflow flowing into the fine filter 53. The airflow containing fine dust that has not been filtered here passes through the coarse filter 66 and flows toward the second fine filter 55 . The second fine filter 55 filters out the remaining fine dust, and only the air flow, which is essentially air, is sucked into the electric blower 10 and discharged from the exhaust chamber 5 to the outside.

A disposable first fine filter 53 and a second disposable filter are used for dust collection.
The fine filter 55 becomes clogged, resulting in poor ventilation. However, since the cord 18 is normally taken in and out before and after cleaning, the dust removal device 29 and the dust removal striking rod 56 remove dust from the filters 53 and 55 as described above in response to the operation of the cord winding device. The problem will be resolved.

When the disposable first fine filter 53 is filled with dust in this manner, the outer lid 84 is opened as shown in FIG. 7, the lid 83 of the first fine filter 53 is closed, and the first fine filter 53 is pulled out.

Since the inner lid 75 is opened as the first fine filter 53 is pulled out, the first fine filter 53 can be smoothly pulled out. The user then carries the first fine filter 53 and throws it into the trash can.

By setting a new disposable first fine filter 53 in the dust collection case 50 in the manner described above, cleaning can be performed again.

Now, when pulling out the disposable first fine dust filter 53 that is full of dust, if the first fine dust filter 53 is torn 9 or damaged during dust collection, carry it along with the dust collection case 50. .

When the dust collection case 50 is pulled forward, it is removed from the dust collection device storage section 49. It is easy to handle as it can be easily pulled out and carried. It is much smaller than the main body case 1 and does not weigh much, so it is easy to carry.

After carrying it to a trash can or the like, pull out the disposable first fine filter 53 from the dust collection case 50 and throw it away in the trash can or the like. Since the dust collection case 50 is carried together, the dust does not fall through the torn hole in the disposable first fine filter 53, so that very hygienic garbage disposal is possible.

Most of the dust collects in the disposable first fine filter 53, so the inside of the dust collection case 50 does not become very dirty. However, there is nothing wrong with cleaning frequently. It is better to do this when the entire dust collection case 50 is removed. Disposable first
After discarding the fine filter 53, remove the coarse filter 66. Fine dust accumulated in the inner trough or lower part of the second fine filter 55 can be removed. It is a good idea to remove fine dust adhering to the inner valley using something like a spatula.

This vacuum cleaner can be used even when the spare disposable first fine filter 53 is used up. Disposable 1st II
If the second filter 53 is not used, dust will accumulate directly inside the dust collection case 50. Coarse filter 6 for thick dust
The fine dust that has passed through the coarse filter 66 is collected by the second fine filter 55. At this time, a large amount of fine dust accumulates in the second fine filter 55. It is necessary to clean the second fine filter 55 frequently.

When disposing of garbage when the disposable first fine filter 53 is not used, the dust collection case 50 must be carried. The presence of the inner lid body 75 prevents the dust inside the dust collection case 50 from spilling out when the dust collection case 50 is pulled out or carried.

Since the machine part 74 of the coarse filter 66 is in contact with the back side of the dust collection case 50 and covers the second fine filter 55, the dust particles are trapped in the valleys of the second fine filter 55. There is no inflow into the country. Although the space between the second fine filter 55 and the coarse filter 66 is small,
The only garbage that accumulates here is fine dust, so it is sufficient.
