Dust collector sucking head and dust collector containing same

Abstract

The invention discloses a dust collector which comprises an air suction pipe and a shell arranged on the outer side of the air suction pipe and is further provided with an air outlet pipe which is isolated from and parallel to the air suction pipe, the air outlet pipe is located in the center of the interior of the air suction pipe, and the cross section area of the air outlet pipe is smaller than or equal to half the cross section area of the air suction pipe. The invention further discloses a dust collector which comprises the sucking head, a sucking rod and a main machine. The sucking rod comprises an air suction channel and an air outlet channel which are connected with the air suction pipe and the air outlet pipe of the sucking head respectively; the main machine comprises an air suction mechanism and an air outlet mechanism, the air suction mechanism is connected with the air suction channel, and the air outlet mechanism is connected with the air outlet channel. According to the dust collector, an air outlet is added, dust or dirt which is located in a carpet, at the root of a hairy fabric and an uneven ground and is difficult to remove is fully dispersed through air flow impact of the air outlet, then a high dedusitng effect is achieved through sucking force of an air suction opening, and cleaning of the environment is achieved more easily.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a vacuum cleaner and a vacuum cleaner including the suction head. Background technique [0002] The working principle of the vacuum cleaner is: there is an electric exhaust fan in the main engine of the vacuum cleaner, which runs at a high speed after being powered on, so that an instant vacuum is formed inside the vacuum cleaner, so that the internal air pressure is much lower than the external air pressure. Under the action of this air pressure difference, dust and dirt As the airflow enters the barrel of the vacuum cleaner, and then passes through the filter of the dust bag, the dust stays in the dust bag, and the purified air escapes into the room through the motor to cool the motor and purify the air. [0003] Existing vacuum cleaners all increase the suction force of the vacuum cleaner on this basis, add various brushes to the suction head of the vacuum cleaner o...

Problems solved by technology

[0003] Existing vacuum cleaners all increase the suction force of the vacuum cleaner on this basis, add various brushes to the suction head of the vacuum cleaner or replace the suction heads of the vacuum cleaner with different sizes to enhance the dust collection effect of the vacuum cleaner, but these improvements are for the bumps that cannot be brushed by the brushes. It is difficult to clean the uneven ground or the roots of carpets and woolen fabrics, and the dust removal effect is not ideal
