Description

[Detailed Description of the Invention] (b) Industrial field of application The present invention relates to a cordless type small vacuum cleaner having a rechargeable secondary battery as a power source, which is attached to a suction port at the front end of a main body case The present invention relates to a storage structure for a nozzle attachment of.

(B) Conventional technology Various structures for accommodating a nozzle for a gap as a nozzle attachment that is detachably attached to the suction port at the front end of the main body case have been proposed.

For example, Japanese Utility Model Laid-Open No. 61-198647 has an electric blower which has a filter for filtering dust provided in front of an electric blower, has a dust inlet at its front end, and has a built-in battery as a power source for the electric blower. In the vacuum cleaner, there is disclosed a vacuum cleaner in which a concave portion is provided on the bottom surface of the main body of the vacuum cleaner, and the vacuum cleaner is detachably accommodated in the suction port.
No. 54648 discloses that a flat tubular suction tool made of a soft material is slidably housed inside a flat tubular suction tool so that it can be stored therein. Disclosed is a suction tool for electric cleaning, which is detachably provided in a concave portion provided by cutting out a fixing base.

Further, the attachments attached to the electric vacuum cleaner include not only the above-mentioned nozzle for gaps but also a nozzle attachment with a brush.

(C) Problems to be Solved by the Invention In the above-mentioned conventional attachment storage structure, no particular structure for reliably storing the nozzle attachment with brush is disclosed. Moreover, since the nozzle attachment with a brush generally has a shape that is bent at an arbitrary angle, if you do not store and hold it securely, the attachment will shift due to vibration or some shock when using the vacuum cleaner in the stored state. Or, there is a risk of falling off due to this deviation.

Therefore, the problem to be solved by the present invention relates to the storage of the nozzle attachment with the brush, which can be easily stored at the time of storage and when the vacuum cleaner is used in the stored state.
The nozzle attachment with the brush may shift due to vibration or some shock, and the nozzle attachment may drop due to this shift, and
It is to provide a structure capable of preventing resonance noise and abnormal noise.

(D) Means for Solving Problems The small vacuum cleaner of the present invention is detachably attached to a main body case having a suction port on one side and an exhaust port on the other side, and the suction port. A nozzle attachment with a brush, the attachment having a cylindrical fitting body that engages and disengages with the suction port, and an opening end having brush bristles and an annular rib, and the annular rib has at least one notch And a storage recess having a surface conforming to the shape of the attachment is formed at the bottom of the main body case, and the storage recess is engaged with the notch and has an inner shape of the annular rib. An insertion rib that can be inserted in one direction and an elastic locking claw that locks an end edge of the fitting barrel portion and urges the annular rib to press the insertion rib are provided.

(E) Action When storing the nozzle attachment with brush in the storage recess on the bottom of the main unit case, insert the annular rib into the insertion rib while engaging the notch of the annular rib of the nozzle attachment with brush with the insertion rib. The end of the fitting body of the attached nozzle attachment is locked by the elastic locking claw in the storage recess.

And a second attachment accommodating recess having a depth dimension larger than that of the first attachment accommodating recess (9) at the rear part of the bottom of the main body case (1) following the first attachment accommodating recess (9). The place (10) is formed. The second attachment accommodating recess (10) is the bottom (1) of the main body case (1).
a) A storage body mounted in the main body case (1) so as to close the rear opening (1b), and a pair of tongue-shaped ribs (11a) extending horizontally on the side walls opposed to each other. )
(11b) and elastic locking claw (12) extending in the vertical direction
Is formed.

(13) has a narrow opening (13a) at one end and an opening (13a) at the other end.
b) is a widened tapered nozzle attachment for a gap, and has a size matching the first attachment accommodating recess (9) at the bottom of the main body case (1). Inside the mounting legs (8a) and (8b) formed at the bottom of the body case (1), a pair of elastic locks formed integrally from the front edge of the second attachment accommodating recess (10). Nail (14a) (14
b) is erected, and locks the rear side of the gap nozzle attachment (13) stored in the first attachment storage recess (9) to prevent it from coming off.

(15) has a fitting body part (15a) with the suction port (2) and a brush mounting substrate (15b) formed at a predetermined angle with the fitting body part (15a), Brush mounting board (15b)
Nozzle attachment with brush bristles, in which a large number of brush bristles (16) are planted in the inner periphery of the bristles (16) planted in a ring shape of the base (15b) on the inner peripheral side. And a pair of notches (17a) are formed at appropriate places on the upper surface of the rib (17). Nozzle attachment with brush bristles (1

(G) Effect of the Invention As described above, the present invention includes a main body case having a suction port on one side and an exhaust port on the other side, and a nozzle attachment with a brush detachably attached to the suction port. In the small vacuum cleaner provided with, the attachment includes a cylindrical fitting body portion that engages and disengages with the suction port, and an opening end portion having brush bristles and an annular rib, and the annular rib has at least one. A cutout is formed, and a storage recess having a surface along the shape of the attachment is formed at the bottom of the main body case, and the storage recess is engaged with the cutout and has the annular rib. It is characterized in that an insertion rib that can be inserted inwardly and an elastic locking claw that locks an end edge of the fitting body portion and urges the annular rib to press the insertion rib are provided.

Therefore, by storing the notched portion of the nozzle attachment with brush while engaging with the insertion rib, the notched portion functions as a guide, and the nozzle attachment with brush can be easily accommodated at a predetermined position of the accommodation recess.

In addition, an insertion rib that engages with the notch and can be inserted into the inside of the annular rib, and an elastic locking claw that locks the end edge of the fitting barrel and presses the annular rib against the insertion rib. As a result, the nozzle attachment with brush is securely locked and stored, so when using a small vacuum cleaner in the stored state, vibration,
It has an effect of preventing the nozzle attachment with the brush from being displaced by an impact of some kind, falling off due to this displacement, and resonance noise and abnormal noise.
