[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, the dust sucked from the floor nozzle concentrates and collides directly from the air intake path with the portion of the paper bag corresponding to the air intake path due to the fast air flow. , fine dust leaks from the paper bag,
There was a problem in that the paper bag would tear if debris such as a crown hit between the ribs.

The present invention solves the above-mentioned conventional problems, and aims to provide a vertical vacuum cleaner in which fine dust is less likely to leak from a paper bag and the paper bag is less likely to be torn.

[0009]

[Means for Solving the Problems] In order to achieve this object, the vertical vacuum cleaner of the present invention is provided with a buffer on the inner surface of the dust collecting section cover corresponding to the air intake path. Further, a dome-shaped protrusion is provided on the inner surface of the dust collection lid corresponding to the intake passage. As another means, an elbow portion connected to the end of the intake passage is provided. A paper bag with a longitudinal reinforcing material attached to the inner surface corresponding to the air intake path is used, or a paper bag is provided with an adhesive attached to the inner surface corresponding to the air intake path.

0010

[Operation] With this structure, the paper bag is brought into close contact with the cushioning body to create an air-impermeable state, thereby alleviating the impact exerted on the paper bag of the sucked-in solid object, such as a crown.

[0011] Furthermore, the paper bag is in close contact with the dome-shaped protrusion, creating an air-impermeable state and allowing smooth air flow.

[0012] Furthermore, the elbow portion prevents the air flow from concentrating on a portion of the paper bag. Furthermore, the pressure loss of the paper bag corresponding to the air intake passage increases, reducing the possibility of dirt leaking. Paper bags can be strengthened by attaching reinforcing materials or adhesives can be attached to reduce the possibility of waste leakage.

(Embodiment 1) As shown in FIG. 1, several ribs 17 are provided inside the dust collecting section lid 16, and a soft and impermeable material such as foamed rubber is provided in the portion corresponding to the intake passage 12. A buffer 1 is attached.

As described above, according to this embodiment, the intake path 1
By providing a buffer on the inner surface of the dust collector lid corresponding to 2, the paper bag is in close contact with the buffer, making the paper bag corresponding to the intake path impermeable, preventing air flow from being concentrated and reducing dust leakage. At the same time, even if a solid object such as a crown is sucked in, the shock applied to the paper bag is alleviated by the cushioning body, and damage to the paper bag can be prevented.

(Embodiment 2) As shown in FIG.
A dome-shaped protrusion 2 facing toward the paper bag 14 side is provided on the inner surface of the dust collecting part lid 16 corresponding to 2. The protrusion 2 has an upper side 22 formed substantially horizontally from a position corresponding to the center line of the intake passage 12, and a lower side 23 inclined.

As described above, according to this embodiment, by providing the protruding part on the dust collecting part lid corresponding to the air intake path, the paper bag is tightly fitted into the dome-shaped protruding part, creating a non-ventilated state, and the air flow is prevented. Not only is it possible to reduce dust leakage by preventing concentration, but also the slope of the wall of the protruding portion allows for smooth air flow and reduces pressure loss.

Furthermore, the recess on the outside of the protrusion can be used as a hook handle for carrying the main body.

(Embodiment 3) As shown in FIG.
An elbow portion 24 facing toward the electric blower 5 below the main body is connected to the end portion of the second cylindrical body 11 forming the second cylindrical body 2 on the paper bag 14 side.

As described above, according to this embodiment, since the air flow is not concentrated in one place of the paper bag, the leakage of dirt is reduced, and the paper bag can also be used as a guide when attaching it to the end of the air intake passage. Can be easily set up.

(Embodiment 4) As shown in FIGS. 4 and 5, a paper bag 14 is attached in the longitudinal direction to the inner surface of the paper bag 14 corresponding to the air intake passage 12 of the paper bag 14 made of filter paper, which is attached by the mouth core 13.
This is a structure in which a reinforcing material 25 such as paper or nonwoven fabric that is made of the same material as filter paper or the like or has a strength higher than that is pasted. The reinforcing material 25 can be automatically attached during a series of operations in the manufacturing process of the paper bag 14.

As described above, according to this embodiment, the pressure loss is increased in the portion of the paper bag facing the air intake passage, and the leakage of dirt can be reduced.

[0024] Furthermore, since the work of attaching the reinforcing material can be automated, an increase in cost can be reduced.

(Embodiment 5) As shown in FIGS. 6 and 7, a diameter larger than the diameter of the air intake path 12 is formed on the inner surface of the paper bag 14 corresponding to the air intake path 12 of the paper bag 14 made of filter paper attached by the mouth core 13. The adhesive 26 is attached to a circular portion by spraying or the like.

Note that the adhesive 26 may also contain an insect repellent or an aromatic agent. As described above, according to this embodiment, the pressure loss is increased in the portion of the paper bag facing the air intake path to which the adhesive is adhered, and the leakage of dust can be reduced. It is economical because the amount of adhesive used is minimal.

[0027] Furthermore, when the adhesive contains an insect repellent or an aromatic agent, respective effects can be expected regarding intake and exhaust air.

[0028]

[Effects of the Invention] As is clear from the description of the embodiments above, a buffer or a dome-shaped protrusion is provided on the inner surface of the dust collecting part lid corresponding to the air intake path, and the end portion of the air intake path is By providing a connected elbow part and further arranging reinforcing material or adhesive on the inner surface of the paper bag that corresponds to the air intake path,
