Suction nozzle for vacuum cleaner

Abstract

The present invention relates to a suction nozzle for a vacuum cleaner, which comprises: a case member, which has suction holes to aspirate dust and inlet holes through which air is let in; a rotary member, which is provided in the case member and rotates by the air that is let in through the suction holes and the inlet holes; a power transmission member, which transforms the rotary movement of the rotary member to a linear reciprocating motion; and a punching member, which connects to the power transmission member, wherein the power transmission member includes a cam shaft, which is coupled to the rotary member, and has a phase difference therebetween, and a cam, which connects to the cam shaft. The present invention increases vibrating force and amount and prevents noise occurrence during cleaning.

Description

technical field [0001] The present invention relates to a suction nozzle of a vacuum cleaner, and more particularly to a suction nozzle of a vacuum cleaner in which camshafts of a power transmission part located inside the suction nozzle of the vacuum cleaner have a phase difference from each other. Background technique [0002] Generally, a vacuum cleaner is a device that uses a suction motor installed inside the main body to suck dust and foreign objects together with the air and then filter them inside the main body. [0003] Vacuum cleaners having the above-mentioned functions are generally classified into a cylinder type in which a mouth serving as a suction port communicates with a main body through a connecting pipe, and an upright type in which the mouth is integrated with the main body. [0004] The cylinder vacuum cleaner includes: a vacuum cleaner body, which contains a suction motor that generates suction force, etc., a suction nozzle, which sucks dust and foreig...

Problems solved by technology

[0008] However, such a device for removing dust and foreign matter has little effect of raising fine dust and foreign matter that exist on the surface to be cleaned of bedding such as carpets or quilts due to its weak vibration amount and vibration force. question

[0009] In particular, since home appliances such as vacuum cleaners are used in North American countries with a supply of 110 volts, the number of rotations per minute (RPM) of the suction motor inside the main body is lower than that in Korea, which further reduces the performance of the above-mentioned fans.

[0010] And, for the device for removing dust and foreign matter, there is a problem that the amount of vibration of the device for removing dust and foreign matter is small because the above-mentioned cam reciprocates once when the fan rotates once.

[0011] On the other hand, since the device for removing dust and foreign matter is placed on the outer surface of the suction nozzle of the vacuum cleaner and vibrates, there is a problem that the device collides with the suction nozzle during cleaning and generates noise.
