Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an electric refilling machine in which a bag-shaped filter such as a paper bag as a gift is placed in a dust case.

Conventionally, in order to remove a small amount of air, one bag-shaped filter could be attached and detached using a lid with an air intake port attached to the dust case, as shown in Japanese Patent Application Laid-Open No. 5/1987-287!14, etc. It is performed by opening and closing the body.

That is, when taking out the bag-shaped filter housed in the dust case after collecting dust, the user had to open the lid to take it out, which made one's hands dirty, which was unsanitary. Also, if the bag-shaped filter is made larger to increase the dust collection space, it will get caught on the inner surface of the dust case after collecting dust, making it difficult to remove it.
If I pulled it out forcibly, it would tear and the dust would get dirty.

Furthermore, if the bag-shaped filter is made easier to remove, the filter becomes smaller and dust collection cannot be increased, resulting in a single-routing operation, which has fewer advantages than a general vacuum cleaner without a bag-shaped filter.

Present inventions 1, 7, and i: This invention has been made to solve the drawbacks described above, and its features include a main body case in which an electric blower is housed, and a main body case that is detachably connected to the main body case.

What is the difference between an intake port and a dust disposal port, and a dust case that is housed in a removable bag-like filter? 1. The intake port is formed in a lid body that can be opened and closed freely to the dust case. At the same time, a bag-shaped filter connected to the intake port and attached to the inner surface of the lid body is configured to be discharged from the dust disposal port.

The invention will now be described according to embodiments shown in the drawings.

Furthermore, another embodiment of the engagement/disengagement device G11l will be explained based on FIG. 10.] Then, the operation lever C3! There is a rotating cam in 'il b)
A spring (56) is arranged to bias the pivot shaft 5 downward.
Due to the force, the filter unit [19 is rotated and the partition plate (
When 13) is released, the %R'J rotation turning cam 5) rotates, and the suppression of the bag openings (41J) of the bag-shaped filter openings is released.

Next, the usage status will be explained.

First, we will explain the case where a bag-shaped filter (4) such as a paper bag is used.

When the push button 181 is pressed, the clamp Tln of the Rin 01 moves upward against the force of the spring (1υ) and is released from its hold.
The force of the spring causes the support shaft a31v to open toward the eye as a fulcrum.

Grasp the bag-shaped filter C321 at the bag opening (41 &) and insert it along the left and right pair of elastic plates + 4:9 (T: end retaining protrusion + 44) along the 4:1 guide until it reaches the bag opening. (4υ is an elastic plate (・f3H, convex part 1 of I31 1!1511+
15) is held in contact with the side. Therefore, S body +ll)
When the base is closed, the bag-shaped filter (c) does not shift its position.

Next, when the lid body 11α is secured to the dust case (5), a pair of left and right guide walls formed in the dust case (5) are tapped [4'? ] by the elastic plate (4th floor (431) is expanded to release the holding of the bag opening (4υ). At the same time, the tip of the operating lever G51 of the locking/disengaging device (to) Because it protrudes to the side, the bag opening (4υ above) of the bag-shaped filter (G) is held between the protrusion (58) of the miJ tray lid 01.
T: The end is a locking protrusion.

Therefore, even if the lid 111Y is opened after sucking in dust, the bag-shaped filter (33 bag opening (4υ is the lower end locking protrusion)
44J (44) and the locking/disengaging device is held in place by the operating lever c151, and the degree of clogging of the dust can be seen.

By opening J and opening the filter unit (i.e., filter unit) that allows the bag-shaped filter C+a to be discarded, the non-ventilated partition plate C releases the locking/disengaging device (c), and the spring (g) releases the operating lever c151. is moved backward, and the upper end of the bag opening (4υ) is released. As a result, the lower end of the bag opening (4υ) of the bag-shaped filter C321 is attached to the retaining protrusion (44).
(44) & climb over, and the bag-shaped filter 03 is discharged to the outside from the waste disposal port (2). Also, the locking/unlocking device (c)
Since it is moved in parallel with the pre-filter R and 3U, the distance from the bag opening (41) of the bag-shaped filter (321) can be greatly reduced, allowing for one-touch engagement and disconnection without any scratches. When the filter C14 is used up, it can be used as usual. In this case, the dust collected in the coarse dust space 6 and the fine dust space (6) should be removed by opening the filter unit (1!i). To do this, you should open your mouth (2 (1)
more is discharged to the outside.

As mentioned above, the vacuum cleaner according to the invention has an air intake port formed in the body that can be freely opened and closed into the dust case, and a bag-like filter that communicates with the air intake port and is attached to the inner surface of the +irJ recording body. Since it is designed to be discharged from the waste disposal port, if the disposable bag-like filter can be easily held in the dust case, the bag-like filter with dust accumulated on its side can be discharged without getting the hands dirty. In addition, by utilizing the tapered shape of the dust case, the bag-shaped filter is held on the 011 part with a small enclosure shape, and it can be discharged from the large cross-sectional area of the dust disposal opening.
The bag-shaped filter can be simply thrown away in the dust case.

'Even if you increase the size of the bag-shaped filter and increase the number of dust collectors, it can be disposed of with a single touch through the wide opening of the dust case.

Furthermore, since the candy can be set on the lid, the bag-like filter will not be damaged by the closing operation of the holder, making it easy to remove several pieces.
