Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an auxiliary dust collector that is detachably attached to an air passage of an air suction type vacuum cleaner usually called an electric vacuum cleaner.

[0002]

[Prior art]

 The dust collecting mechanism of the conventional air suction type vacuum cleaner is composed of a hose and a dust collecting chamber, the hose is composed of a pipe or a flexible pipe with a substantially uniform pipe diameter, and the dust collecting chamber is the final end of the air passage. It is made up of a cloth-like bag with a paper or non-woven fabric filter inside that can separate air and dust and dirt from the air passage, and most dust and dirt sucked from the air passage is collected by the filter. To be done. Usually, the filter is detachably attached to the dust collection chamber and is discarded together with the collected dust.

[0003]

[Problems to be solved by the device]

 In the conventional air suction type vacuum cleaner described above, when a sharp object such as a needle or a pin is sucked during air suction, it may cause a hole to leak in the filter and may be dangerous when the filter is attached or detached. There was a problem such as jewelery accessories being sucked without being noticed and discarded together with the filter.

An object of the present invention is to provide a device that can easily collect dust of a material having a relatively high specific gravity before being collected in the dust collection chamber.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the supplementary rib dust collector according to claim 1 is provided with an air passage branched in a T shape at an arbitrary position of an air passage of an air suction type vacuum cleaner, and the air passage of the air passage is A partition plate or a narrowed portion is provided near the branch portion, and the auxiliary dust collector according to claim 2 is characterized in that the detachable dust collector is provided at the branch portion.

Regarding the position and angle of the partition plate in the configuration of the present invention, the angle between the partition plate and the axis of the air passage in FIG. 1 is in the range of 60 ° to 80 °, and in FIG. The angle between the plate and the axis of the air passage is in the range of 70 ° to 85 ° or 95 ° to 110 °, and the area ratio between the air inlet and the air outlet partitioned by the partition plate at the branch point is It is desirable to be in the range of 1: 2 to 1: 4.

The auxiliary dust collector according to the first aspect of the present invention may have a narrowed portion as shown in FIG. 3 instead of the partition plate.

[0008]

[Action]

 The basic principle of this invention is to apply the turbulent action of fluid, and it will be explained based on the figure. In FIG. 1, air is parallel to the inner wall of the pipe of the auxiliary pipe from the direction of arrow A to the direction of arrow B. When flowing, the partition plate is installed at a slight forward inclination angle against the air flow, so the air is pushed down toward the branch part and swirls from the tip of the partition plate to the branch part. Since the partition plate is installed at a slight angle in the horizontal direction as shown in Fig. 5, the vortex of the air rotates horizontally in the dust collecting part. Furthermore, by making the air outflow side larger than the air inflow side by the partition plate in the branch portion, the turbulent flow effect is further promoted.

Due to the formation of the vortex of the air mentioned above, the refuse transported in the air passage is screened according to the difference in specific gravity, and the refuse having a large specific gravity such as metal, stone, glass and plastics is collected in the dust collecting part. Garbage that has been collected and has a low specific gravity, such as paper and fibers, exits the dust collection unit and is collected in the dust collection chamber of the cleaner body.

【Example】

 The structure of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view including a vertical section of the first embodiment, and FIG. 2 is a bottom view of the CC ′ cross section taken along the arrow. FIG. 3 is a side view including a vertical section of the second embodiment.

In FIG. 1, reference numeral 1 denotes an auxiliary pipe, which is a tubular body having a detachable diameter and forms an air passage between hose joints of a conventional vacuum cleaner. A branch portion 11 is provided at the lower center.

Reference numeral 2 denotes a dust collecting part, which is a bottomed cylindrical body having an opening on one side and formed with a transparent synthetic resin and having a depth of about 3 times the diameter. The opening 21 is detachably attached to the branch portion 11 of the auxiliary pipe 1. By attaching the opening 21 of the dust collecting portion 2 to the branch portion 11 of the auxiliary pipe 1, an air passage branched in a T shape and having its tip closed is formed.

A partition plate 3 is provided from the inside of the auxiliary pipe 1 toward the branch portion 11, and its tip is arranged so as to divide the branch portion 11 into an air inlet 11A and an air outlet 11B. . In that area, the air inlet 11A is about one third of the air outlet 11B. Next, regarding the attachment angle of the partition plate, the angle between the partition plate and the inner wall of the auxiliary pipe 1 of the auxiliary pipe 1 is 70 ° in FIG. 1, and the angle between the partition plate 3 and the inner wall of the auxiliary pipe 1 is FIG. It is installed at an angle of 75 ° or 105 °.

FIG. 3 shows a second embodiment of the present invention. Reference numeral 4 is an alternative auxiliary pipe, in which a V-shaped narrowed portion 41 is formed near the branch portion.

The narrowed portion 41 of the second embodiment has the same function as that of the partition plate 3 of the first embodiment.

[0016]

[Effect of device]

 The auxiliary dust collector of the present invention can be attached and detached between the hose joints of the conventional vacuum cleaner, and when the air passes through the auxiliary dust collector of the present invention, the debris transported in the air passage will be removed. It is possible to collect dust having a large specific gravity in the auxiliary dust collector of the present invention, which is sorted by the difference in specific gravity, and the collected dust can be easily taken out.
