Problems solved by technology

[0015] However, if the length of the axial direction of the cyclone separation part and the dust collection chamber is increased, the dust collection chamber and the cyclone separation part with a smaller diameter will be longer, so the phenomenon of dust getting stuck on the inner wall and the narrow road part will be further promoted, so that there will be dust Difficulty in discharge and disposal
Therefore, in actual use, the length of the axial direction in which dust can be discharged is limited, and as a result, there is a problem that the dust collection volume cannot be increased.

Embodiment 1

[0034] Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. figure 1 A perspective view showing the appearance of the electric vacuum cleaner used in the present invention, figure 1 Among them, symbol 101 is a vacuum cleaner main body, and a cyclone dust collector 102 is mounted on the vacuum cleaner main body 101. The vacuum cleaner main body 101 is connected to a hand handle 104 via a suction hose 103, and the hand handle 104 is connected to a suction mouth body 107 via an extension pipe 106.

[0035] And the handle 104 at hand is equipped with the operation part 105 at hand which controls the drive of the electric blower built in the cleaner main body 101, and the electric rotary brush provided in the nozzle body 107.

[0036] figure 2 Shows a cross-sectional view of the vacuum cleaner main body 101 cut approximately in the center, and a hose attachment port 201 is formed in a casing 204 of the vacuum cleaner...

Embodiment 2

[0094] Next, the second embodiment of the present invention will be described in detail with reference to the drawings. Since the main body of the vacuum cleaner basically has the same structure as that of the first embodiment, the dust collector will be described below.

[0095] Image 6 It shows the cross-sectional view which cut the cyclone type dust collector 601 which concerns on 2nd Embodiment of this invention substantially in the center.

[0096] Image 6 Among them, the dust collector 601 is composed of a cyclone separation unit 602 that separates dust and air by centrifugal force generated by rotating air containing dust, and a dust collection chamber 603 that stores separated dust.

[0097] As shown in the drawing, a dust collection chamber 603 for storing separated dust is disposed adjacent to the lower side of the cyclone separation unit 602 . The cyclone separation unit 602 and the dust collection chamber 603 are integrally formed so that they cannot be separat...

Embodiment 3

[0125] Next, the third embodiment of the present invention will be described in detail with reference to the drawings. Since the main body of the vacuum cleaner basically has the same structure as that of the first embodiment, the dust collector will be described below.

[0126] Figure 8 It shows the cross-sectional view which cut the cyclone type dust collector 801 which concerns on the 3rd Embodiment of this invention substantially in the center.

[0127] Figure 8 Among them, the dust collector 801 is composed of a cyclone separation unit 802 that separates dust and air by centrifugal force generated by rotating air containing dust, and a dust collection chamber 803 that stores separated dust.

[0128] As shown in the drawing, a dust collection chamber 803 for storing separated dust is arranged adjacent to the lower side of the cyclone separation unit 802 . The cyclone separation unit 802 and the dust collection chamber 803 are integrally formed so that they cannot be se...

Abstract

The invention provides an electric dust collector. When a cover body arranged at the lower part of a cyclone separation part is opened to discharge dust, the size of the fabric dust compressed during the attraction is enlarged so that the dust is clamped on the inner wall and narrow part of a dust collecting chamber or the cyclone separation part, thereby increasing the difficulties in dust discharging and abandon. Therefore, a part of the side surface of the dust collecting container is provided with an opening for discharging dust and a cover body for opening and closing the opening, and the accumulated dust is discharged from the opening by opening the cover body. The electric dust collector provided can ensure that the opening area provided is larger than the opening area determined by the diameter of the cyclone separation part and the dust collecting chamber, thereby facilitating the dust discharging.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner including a dust collection chamber that can be attached to and detached from a vacuum cleaner main body. Background technique [0002] For an existing general electric vacuum cleaner, there is a vacuum cleaner main body equipped with a dust collecting device and a floor suction body for sucking dust from the floor, and an extension pipe or a suction hose is used to connect the vacuum cleaner main body and the floor suction body. It is called a floor mobile electric vacuum cleaner. [0003] The vacuum cleaner body of such an electric vacuum cleaner includes a dust collector and an internal electric blower, and is configured to be movable via wheels. Here, as an example, let a dust collector be a cyclone system. [0004] The cyclone type dust collector is configured to separate the dust-containing air sucked in from the suction port into ai...
