Description

[Detailed explanation of the idea] (b) Industrial application fields This proposal relates to a small portable vacuum cleaner.

(b) Prior Art The present applicant has already proposed a cordless, small, portable vacuum cleaner that uses paper filters such as tissue paper, which are inexpensive and easily available (patent application). (See No. 1983-83101). In this product, a dust collection case for reinforcing the paper filter is removably stored in the dust collection recess of the main body of the vacuum cleaner, but this dust collection case must be accurately positioned and stored in the dust collection recess. There is a risk that the sealing between the dust collection recess and the opening/closing lid may be inadequate, resulting in dust not being collected effectively.

(c) Problems to be solved by the invention The vacuum cleaner of the invention enables the dust collection case that houses the paper filter to be stored in a predetermined position within the dust collection recess of the vacuum cleaner body. At the same time, the dust collection case can be easily removed from the dust collection recess.

(d) Measures to solve the problem The vacuum cleaner of the present invention has a main body with an upwardly opening dust collection recess in the front part and a built-in fan motor in the rear part.
The dust collecting recess has a lid body that opens and closes the upper opening of the dust collecting recess, and a packing frame body that is held between a filter part, an opening edge of the dust collecting recess, and the lid body, A dust collection case installed in the recess,
and a paper filter housed in the dust storage case, and the packing frame is provided with a tongue piece disposed outside the opening edge of the dust storage recess and covered by the lid body. There is.

(E) Function The dust collection case is positioned with its packing frame and tongue piece straddling the upper opening edge of the dust collection recess, and is housed in the dust collection recess, with the upper opening completely sealed by the lid. be done. Further, the packing frame body will not be deformed when dust is sucked in. Furthermore, when disposing of trash, the dust case is removed from the dust collection recess by grasping and pulling the tongue piece with the fingers.

(f) Example 1 is the main body of a small portable vacuum cleaner, which includes a fan motor 2, a sliding power switch 3, and a power battery 4.
It has an equipment storage part 6 in the rear part which is equipped with electrical equipment such as and has a handle 5 formed thereon.
an upper-opening dust collection recess 9 that communicates with the air intake port 7 through the air intake port 7 and has a first opening 8 for fitting the air intake port at the front side;
It has at the front. The upper side wall 10 constituting the dust collection recess 9 is formed by entering inside the dust collection recess 9 from the lower side wall 11, and a lid is provided at the folded part between the upper side wall 10 and the lower side wall 11. A body engagement groove 12 is formed.

Reference numeral 13 denotes a lid body that freely opens and closes the upper opening of the dust collection recess 9 of the main body 1;
It is rotatably attached to the main body wall located above via a hinge mechanism 14, and also covers the upper side wall 10 at the same time when the upper opening is closed, and its lower end is connected to the lid engagement groove 12. It has hanging pieces 15 on the left and right portions of both ends that come into contact with, and when closed, always engages with the engagement hole 16 of the main body 1 to maintain the closed state and presses a button 17 protruding from the hanging pieces 15. A U-shaped synthetic resin stopper member 18 is provided, which is bent to release the engagement relationship and open the lid body 13.

Reference numeral 19 denotes an upper opening removably installed in the dust collection recess 9, and a second opening 2 for fitting the suction port in the front.
0, the housing-like mesh filter part 21 is housed with a space between the inner wall of the dust collecting recess 9, and the upper opening edge 22 of the dust collecting recess 9 has the same shape. When the lid 13 is closed, the lid 13
It has a packing frame 24 made of flexible synthetic resin that is pressed by a protrusion 23 and held between the upper opening edge 22 and the lid 13, and the packing frame 24 further includes: An annular hanging portion 2 enters the dust collection recess 9 from inside the upper opening edge 22 and has the opening end of the mesh filter portion 21 attached thereto.
5, and furthermore, there are hand-held tongue pieces 2 on both the left and right sides of the outside.
6 and 26 have been extended. The tongue piece 26 is positioned outward from the upper opening edge 22 when the dust case 19 is housed in the dust collection recess 9 and is held between the upper side wall 10 and the hanging piece 15 of the lid body 13. Therefore, the packing frame 24 is accurately positioned and held by the tongue piece 26 while straddling the upper opening edge 22, and the dust storage case 19 is It is stored in a predetermined position within the dust recess 9 without being deformed. Further, the dust case 19 can be pulled out from the dust storage recess 9 by grasping and pulling the tongue piece 26 with the fingers.

Reference numeral 27 denotes a filter holding body that is installed in the dust storage case 19, and this holding body 27 has a pair of paper holding members that are inserted into the dust storage case 19 on the back side of a substrate 28 that covers the upper opening of the dust storage case 19. rib 2
9 and 29 are planted downward, and further this substrate 28
protrudes from the first and second suction port fitting openings 8 and 20, and a cylindrical suction port 30 for guiding dust to the dust storage case 19 is provided below the projecting portion. This suction port 30 has a small diameter suction portion 30a that fits into the openings 8 and 20.

Reference numeral 31 denotes a paper filter made by using commercially available tissue paper or kitchen paper as is, and this paper filter 31 has its central portion placed in the upper opening of the dust collection case 19 installed in the dust collection recess 9. By fitting the filter holding body 27 into the dust storage case 19, the paper holding rib 29 of the filter holding body 27 expands the central portion into the dust storage case 19, creating a wide dust storage space. The filter holding body 27 and the dust collecting case 19 are introduced into the dust collecting case 19 in a state having
It is caught between. Then, the peripheral end 31a of the paper filter 31 is folded back onto the surface of the substrate 28 of the filter holder 27, and the dust collection lid 13 is closed, so that the peripheral end 31a is placed between the filter holder 27 and the lid 13. is maintained.

(g) Effects of the invention According to this invention, the dust collection case that reinforces the paper filter is accurately positioned and stored in the dust collection recess, and a good sealing condition with the lid body can be maintained, which improves the dust collection efficiency. will not deteriorate. In addition, the tongue on the dust case prevents the dust case from deforming even when dust is inhaled, and when disposing of garbage, you can easily remove the dust case from the dust recess by grasping and pulling the tongue with your fingers. It can be pulled out for easy garbage disposal.
