TECHNICAL FIELD The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner that sucks this material by suction force.

The vacuum cleaner is a cleaning device that absorbs dust and the like by using the absorbing power of the low pressure part. Vacuum cleaners are also called electric cleaners. The dust on the carpeted living room is absorbed and cleaned by air absorption. It is convenient to clean every corner of the room, and when cleaning a large living room, plug the cord into a wall outlet and push it around to absorb dust. It's convenient to plug in the cord that's not too long. After cleaning, turn off the switch, unplug the cord, open the lid of the dust box and shake off any accumulated dust.

The structure consists of the suction port, motor, rotary vane, filter, dust collecting case and exhaust port. The operation process is as follows. A commutator motor rotates the rotor blade more than 10,000 times to make the inside vacuum and sucks in dust or debris through the inlet. Sucked dust and debris is filtered out of the filter and air is exhausted through the exhaust vent. It also has a function of winding the power cord automatically. Also, a gear is operated when the power cord is unplugged or wound to automatically shake off the dust attached to the filter. The suction port is also designed to be easy to use depending on the place of use.

Types include ① hand type, ② upright type, ③ pot type, and ④ cylindrical floor type. The hand type is suitable for dust collection on desks, shelves, clothes, etc. The upright type has a smaller weight than the hand type and can be used for floor cleaning, but the dust collection capacity is small. Cylindrical floor type is widely used for home use because of large dust collection capacity, and there is also a sound-proof model that greatly reduces motor noise with power consumption of 600W or so.

And the vacuum cleaner as described above generally has a suction nozzle which is detachably coupled with the extension tube for transmitting the absorption force, the suction nozzle has a variety of shapes according to the purpose of cleaning.

A first coupling part fitted with the end of the second coupling part and a second coupling part fitted with the coupling pipe of the suction nozzle, wherein the first coupling part and the second coupling part are respectively increased as the inner diameter thereof is directed toward the end thereof. Disclosed is a nozzle adapter of a vacuum cleaner, characterized in that the outer diameter of the vacuum cleaner decreases toward the end.

The first coupling portion and the second coupling portion may be configured to have different inner and outer diameters, and the inner diameter of the first coupling portion may be larger than the outer diameter of the second coupling portion, or the first coupling portion or the second coupling portion. At least one of the parts may be coupled to a cover. The cover may be formed with a plurality of through holes through which air can be communicated.

A coupling tube for coupling with an end of an extension tube connected to a suction force generating unit for generating a suction force; And a suction nozzle coupled to the end of the coupling pipe to suck foreign matter with suction power transmitted by the suction force generating unit, wherein the coupling pipe is formed to be smaller than the inner diameter of the extension pipe, and the recess is inserted into the extension pipe. It is formed, it provides a suction nozzle of the cleaner, characterized in that the groove is covered by a close contact member having a ductile so as to be in close contact with the inner peripheral surface of the extension tube when the coupling tube is fitted to the extension tube.

One or more annular grooves may be formed on the outer circumferential surface of the coupling pipe.

The adhesive member may be applied to only one side of the adhesive material that can be bonded toward the outer peripheral surface of the coupling tube.

The coupling tube may have a tapered shape in which at least a portion of the recessed portion is formed to have an outer diameter smaller in the longitudinal direction thereof.
