Abstract

PURPOSE:To enable a lighting lamp and a belt to be easily exchanged and an internal section to be easily cleaned by fitting the lighting lamp on the upper section of a brush cover body, and by supporting the brush cover body with the front section fixed to be retained with an upper case and a lower case, pivotally and rotatably in a main body case. CONSTITUTION:In a main body case 2, a rotary brush 10 to be rotated by belt-driving from a driving source 11 is faced a suction port 3 and is contained to be pivotally supported, and a brush cover body 19 for covering the upper surface of the rotary brush and setting a lighting lamp 29 on the upper section is contained, and the rear section of the cover body is supported pivotally, rotatably, and coaxially with the pivotally supporting section of a connecting pipe 13, and the front section is fixed to be retained with an upper case 6 and a lower case 4. With this composition, only by removing the upper case 6, the lamp 29 is exposed and so the lamp 29 can easily be exchanged. Besides, in this state, the front section 19a of the brush cover body 19 is turned free, and so, when the brush cover body 19 is rotated to be directed up ward, the upper surface section of the rotary brush 10 is opened. Accordingly, the cleaning of the internal section including the rotary brush 10 can easily be executed, and the belt 12 and the rotary brush 10 can also be easily exchanged.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a floor suction tool equipped with an illumination lamp and a rotating brush.

(b) Conventional technology Regarding this type of floor suction device, Japanese Patent Application Laid-Open No. 57-55120 discloses a method of rotating the internal space of the rotating brush storage chamber by providing a brush cover body in the upper part of the rotating brush storage chamber. The rotating diameter of the brush is not larger than necessary, thereby preventing a drop in the wind speed in the rotating brush storage chamber, preventing the sucked up dust from falling again, and preventing a drop in suction power. has been done. However,
In this conventional technology, the brush cover body is screwed to the upper case of the main body, which makes the assembly work troublesome, and the brush cover body cannot be easily removed from the upper case, so the space between the upper case and the brush cover body is used. It is difficult.

Furthermore, Japanese Utility Model Application No. 55-1441 discloses a floor suction device equipped with an illumination lamp, but this prior art has the lamp housed in a lamp cover protruding from the upper surface of the upper case of the main body. The lamp cover is fixed to the main body case with screws, or the lamp holder with the lamp attached is inserted into the lamp cover through a hole provided in the upper case of the main body facing the lamp cover and held. The structure is complicated and the lamp replacement work is difficult.

(c) Problems to be Solved by the Invention The present invention has a simple structure that allows the brush cover body to be stored in the main body case, and also allows for easy replacement of lighting lamps and belts without losing the brush cover body. To obtain a floor suction tool which is easy to use and which allows easy cleaning of the interior.

(d) Means for Solving the Problems In order to solve the above problems, the floor suction tool of the present invention includes a main body case consisting of an upper case having a light-transmitting part and a lower case having a suction port; A connecting pipe is rotatably attached to the rear of the case, and a rotary brush rotated by a belt drive from a drive source is pivotably housed in the main case facing the suction port. A brush cover body that covers the upper surface and has an illumination lamp disposed thereon is housed, the rear part of the brush cover body is rotatably supported coaxially with the pivot part of the connecting pipe, and the front part is rotatably supported by the pivot part of the connecting pipe. It is characterized by being clamped and fixed between the upper case and the lower case.

(E) Effect With the above configuration, the brush cover body is arranged in the main case by having the rear part coaxially supported with the pivot part of the connecting pipe and the front part being held between the upper case and the lower case. Ru.

In addition, by removing the upper case, the lighting lamp is exposed and the lamp can be replaced.Furthermore, the front part of the brush cover body becomes free in this state, so when the brush cover body is rotated, the top surface of the rotating brush can be removed. The opening allows you to replace the belt and clean the interior, including the rotating brush, without removing the brush cover.
