Problems solved by technology

[0004] But, in the above-mentioned existing dust-absorbing head structure, when the band-brush-absorbing head is installed on the dust-absorbing head main body, it must be completely aligned with the installation space for inserting the band-brush dust-absorbing head before it can be installed. Otherwise it won't fit in
Therefore, there is a problem that it is difficult to operate when reinstalling the brushed cleaning head.

Embodiment Construction

[0024] A first embodiment of the present invention will be described below with reference to FIGS. 1 to 6. FIG.

[0025] As shown in Figure 1, the electric vacuum cleaner 1 has: an extension tube 3 with a dust suction head assembly 2 detachably arranged on the front end; an armrest handle 4 connected with the other end of the extension tube 3; , the hose 5 that is connected to the hose connector 6 at the other end. The hose connector 6 is connected to the main body 7 of the vacuum cleaner.

[0026] The cleaning head assembly 2 is composed of a small suction head 11 and a floor suction head 12 on which the small suction head 11 is detachably mounted. The small suction head 11 is provided with a connection pipe 8 connected to the extension pipe 3 in a detachable manner, and a suction head 10 connected to the connection pipe 8 through a connection member 9 .

[0027] Additionally, if figure 2 ~ As shown in Figure 6, a small suction head installation pit 16 roughly matching the...

Abstract

Provided is a suction device for a vacuum cleaner having a small-size nozzle with superior attachment / detachment performance and to provide a vacuum cleaner.This suction device is provided with the small-size nozzle 11 having a suction head 10 which is formed with a tip suction port 18, a small-size nozzle storage recess 16 detachably storing the small-size nozzle 11, and a floor nozzle 12 provided in the small-size nozzle storage recess 16 and having a projection part 23. When the small-size nozzle 11 is stored in the small-size nozzle storage recess 16, the projection part 23 is inserted in the tip suction port 18, so that the tip suction port 18 of the small-size nozzle 11 is guided by the projection part 23 and surely installed therein.

Description

technical field [0001] The invention relates to a dust-absorbing head of an electric vacuum cleaner and an electric vacuum cleaner using the dust-absorbing head. Background technique [0002] In some existing electric vacuum cleaner cleaning heads, on the front end of the extension tube connected to the main body of the vacuum cleaner, a cleaning head with a brush (also known as a "small suction head") is connected through a connecting part that can rotate freely up and down. The cleaning head with the brush is connected with the connection port on the upper surface of the cleaning head main body (also known as "floor suction head") in a rotatable and detachable manner. This dust suction head with a brush is provided with a suction port opening downward, and brushes are arranged around the suction port. When vacuuming a narrow place that is difficult to clean with the main body of the cleaning head, the cleaning head with brush can be detached from the main body of the clea...
