Description

[Detailed description of the invention] This invention relates to a small electric vacuum cleaner, and by devising the implantation of the brush in the dust case, it is relatively inexpensive and can be made with suitable flexibility even when the material is not very thin in diameter. The purpose is to make it possible to have a sense of well-being.

In general, small electric vacuum cleaners make it easier to suck in dust by bringing the bottom surface of the dust case closer to the surface where dust is scattered, by approximately 4 mm or less, but the suction port is designed to make it easier to suck in dust, etc. Traditionally, several rows of brushes are embedded in the dust case to guide the dust and move smoothly over the surface to be cleaned. However, the length of the brush cannot be made too long because it brings the bottom surface of the dust case closer to the surface where dust etc. are scattered.
As a result, the length of the brush becomes shorter, so
(1) The brush loses its flexibility and becomes hard and difficult to handle. (2) In order to make the brush flexible, the brush must be made of an expensive material with a relatively small diameter. (3) When external force is applied, the brush bends significantly from the root of the implant, which tends to permanently deform and remain broken. (4) It is difficult to insert a brush into the sloped surface of the bottom of the dust case. There were other problems.

The present invention has been made to solve the above-mentioned conventional problems, and one embodiment of the present invention will be described below with reference to the drawings. In Figure 1, 1
1 is a main body case that houses a motor, blades (none of which are shown), etc., and a dust case 2 is detachably attached to the lower part of this main case 1. 3 is a suction port provided in the center of the dust case 2; 4 is a sloped lower surface provided on the bottom surface of the dust case 2 from the outer periphery toward the suction port 3 in the center; 5 is a number of rows planted on the dust case 2; This brush 5 has functions such as collecting dust. Reference numeral 6 denotes a mounting surface of the brush 5, and this mounting surface 6 is configured to be concave with respect to the inclined lower surface 4 of the dust case 2. Therefore, the length of the brush 5 is the first
As shown in the figure, it becomes x+y.

Figures 2 and 3 are cross sections perpendicular to Figure 1;
It shows the implanted state of the brush 5.

In the configuration shown in FIG. 1, the length of the conventional brush 5 is x at the shortest point and becomes longer along the inclined lower surface 4. In this case, the flexibility of the brush 5 is Since the protruding lengths are different from those of 4, it becomes unbalanced. However, in the present invention, since the implantation surface 6 of the brush 5 is configured to be concave with respect to the inclined lower surface 4 of the dust case 2, the length of the brush 5 can be ensured to be the length x+y. , Therefore, if the length of y is appropriately considered, the following various practical effects can be achieved.

(1) Appropriate flexibility can be obtained even if an inexpensive material with a relatively large diameter is used as the material for the brush 5.

(2) Since the implantation surface 6 of the brush 5 can be made flat, the implantation process becomes easy.

(3) Since the length of the brush 5 protruding from the implantation surface 6 is constant, the flexibility is also uniform.

(4) Even when a bending force is applied to the brush 5 as shown in FIG.
Since it hits the corners 7 and 8 of the brush 5, it is possible to prevent the brush 5 from breaking from the base.
