Dust collector head

Abstract

The invention discloses a dust collector head, which can easily sliding over a foreign matter bump through a slidable dust collection tube, ensure the continuity of the dust collection action, and improve the dust cleaning efficiency. The dust collector head is characterized in that one end of a connection sleeve is arranged on one end of a dust collection sleeve in a sleeve way, and is screwed with the dust collection sleeve; the other ends of a protection plate and the connection sleeve are screwed through threads; the protection plate has a circular plate structure; the inner wall of the connection sleeve is provided with a connection plate; the connection plate is positioned between the protection plate and the dust collection sleeve; the connection plate and the connection sleeve aremolded integrally; the other end of the dust collection sleeve has a conical structure; the diameter of the dust collection sleeve decreases gradually from one end of the dust collection sleeve to theother end; the diameter of a port at the other end of the dust collection sleeve is a half of the diameter of a port at one end of the dust collection sleeve; a screw sleeve is connected with the other end of the dust collection sleeve; and one end of a metal hose is screwed with the screw sleeve.

Description

technical field [0001] The invention relates to a dust-absorbing head of a vacuum cleaner, which relates to a dust-absorbing and dust-absorbing head for a smart device, and belongs to the field of dust-removing equipment. In particular, the utility model relates to a vacuum cleaner head which can easily slide over the protrusions of foreign objects through a slidable dust suction tube to ensure the continuity of the dust suction action and improve the efficiency of dust suction and cleaning. Background technique [0002] During the daily use of modern smart devices, there will be a certain amount of dust inside, and it is necessary to clean and maintain the inside of the machine regularly. However, due to the precise wiring layout and complex structural design inside the smart device, it is necessary for personnel to clean the inside of the device. It is inconvenient when people use the existing vacuum cleaner head to move and vacuum inside, and they are often easily blocked...

[0002] During the daily use of modern smart devices, there will be a certain amount of dust inside, and it is necessary to clean and maintain the inside of the machine regularly. However, due to the precise wiring layout and complex structural design inside the smart device, it is necessary for personnel to clean the inside of the device. It is inconvenient when people use the existing vacuum cleaner head to move and vacuum inside, and they are often easily blocked by raised foreign objects, resulting in incoherent cleaning actions and unsmooth cleaning sequences, which affect the normal cleaning efficiency of personnel

[0003] The notification number CN107225121A discloses a device for cleaning and processing dust inside high-voltage electrical equipment, which includes a dust suction device, the dust suction device includes a central dust suction pipe, and the lower end of the central dust suction pipe connects with the dust suction connection pipe. A control device with a dust suction fan inside is connected, and a positioning circular plate is threaded outside the lower part of the central dust suction pipe. A cleaning device is provided outside the central dust suction pipe above the positioning circular plate. A high-pressure cleaning device is fixed above the positioning circular plate. When the cleaning part of this device encounters a foreign object protruding inside the equipment, it needs to be lifted by personnel to clean it over the protruding part. The cleaning action is not smooth and inconvenient.

[0004] The notification number CN207341713U discloses a dust removal device for electric equipment, including a dust removal box body, a dust storage room is opened inside the dust removal box body, a housing is provided outside the dust removal box body, and the left side of the dust removal box body is The side is fixedly connected with a first dust suction hose, the left side of the first dust suction hose is movably connected with a control lever, and the left side of the control lever is movably connected with a telescopic tube, although this device can control the vacuum hose extended length, but the overall adjustment operation takes a certain amount of time, which is not suitable for quick cleaning and vacuuming
