Description

[Detailed Description of the Invention] The present invention is used as a suction attachment for a widely used vacuum cleaner that utilizes the action of a blower that rotates a built-in fan to suck in air from one side and exhaust air from the other side. For example, the bristles of the rotating brush with bristles built into the inhaler with a rotating brush are as follows.
The present invention relates to a method for removing static electricity generated by flocking when the carpet rotates while coming into contact with the carpet.

The present invention will be explained below by way of an example.

FIG. 1 is a perspective three-dimensional view showing a state in which a suction device for a vacuum cleaner incorporating a rotating brush according to the present invention is used in conjunction with a vacuum cleaner, and FIG. 2 is an external appearance of a suction device incorporating a rotating brush according to the present invention. Figure 3 is a bottom view of the inhaler shown in Figure 2 seen from the bottom, Figure 4 is a perspective view of the inhaler shown in Figure 2
Fig. 5 is a perspective three-dimensional view of the rotary brush, Fig. 6 is a front view of the rotating brush with the brush stand partially cut away and both ends cut out, Fig. 7 is the 6th
Left side view showing the shape of the outer brush of the brush stand shown in the figure, No. 8
The figure is a right side view showing the shape of the outer cover of the brush stand shown in FIG. 6.

The structure of the inhaler according to the present invention and the function of each part will be explained with reference to the drawings.

In the figure, 1 is an inhaler, 2 is a storage for the following parts,
Bottle 13 installed in the actuator is made of a soft material to prevent damage to other objects when using the inhaler 1, and 4 is made of a soft material with kunonyeon 3 sandwiched between it and bottle 2. A cover 5 is attached to cover the upper part of the body 2, and the inhaler 1 is opened at the bottom surface 6 of the body 2.
When using the air intake port 57, which takes in outside air, is a partition plate that crosses inside the body 2, and 8 is a partition plate 7 that faces the intake port 5.
10 is a hollow cylinder that is rotatably supported between the side wall 9 of the vacuum cleaner body 11 and a flexible hose 13 that is connected to the suction port 12 of the vacuum cleaner body 11, and an fco extension pipe that is connected to the end of the flexible hose 13. 14, a connection pipe for connecting the suction device l to the vacuum cleaner main body 11, an inlet 5 through which the air flow generated by the vacuum cleaner main body 11 flows in, an air outlet provided in the partition plate 7, and an air outlet formed by the vent 15 and the connection pipe 10. A fan 16 is rotatably supported in a fluid system by a bearing 18, 182 that supports a rotating shaft 17 at the center thereof. The rotary shaft 17 has a tip 19 formed into a gear and has a tooth profile thereon, and a belt 20 is applied thereto. - Shafts 22 and 22' protruding from both ends 21 and 21' of the rotating brush 8 are pivotally supported on the body 2, and the tip of the shaft 22 forms a gear 23, to which the belt 20 is looped.

The configuration of each of the above parts is the same as that of a suction tool as an attachment for a vacuum cleaner that is generally widely used. Projections 25 and 25' are wound around the brush stand 24 and protrude in this shape, and two rows of bristles 26 and 26 are planted on the brush stand 24. This ridge 25.25' and flocked hair 26.26'
Both angles are 360 degrees in this example, that is, the brush stand 24
The brush base 24 is provided so as to be wound from one end 21 to the other end 21' of the brush stand 24 by one rotation. This hair transplant 26.26
' is located at the intake port 5 and protrudes from the bottom surface 6, and rubs against the surface of the object to remove dust attached to the surface of the object to be cleaned.

This rotary swing 8 is usually used for cleaning floors or similar items; do not rotate the rotary swing 8 for surfaces that are easily damaged by friction, such as floors or dirt. use. Switching is done by sliding along the partition plate 7.
(by moving the knob 28 from the outside of the cover 4 to the "1st" position, the vent 15 will open and the air flow will be caused by rotating the fan 16,・f: ftl
By rubbing, the ventilation port 15 is closed and another air port 15' in the partition plate 7 is opened, so that the air flow is such that the fan 16 does not rotate.

As described above, the rotating brush 8 has flocked hairs 26 and 26' made of natural or synthetic fibers, and as they rub against the surface of the material, static electricity is generated there. It is well understood that the entire inhaler l, including the rotating swing 8, is made of plastic and is therefore easily charged with electricity. For this reason, dust often adheres to and entangles the flocked hairs 26 and 26', reducing the cleaning effect, and it is experienced in practical use that it is necessary to remove one piece of dust each time.

The present invention provides a method for removing static electricity that causes this.

Metal strips, metal pieces, metal mesh, Attach gold foil (ribbon), metal film, etc. to a structure and material that is a good electrical conductor and will not peel off due to friction and wear. These are hereinafter referred to as metal pieces 29.29',
Approach the two rows of flocks 26.26' and insert the protrusion 25.25' into the ridge 26.26'. Article 25
．． 25' is melted and metal pieces 29 and 29' are embedded and fixed in this manner, or the brush stand 24 is coated with a metal film by chemical plating, sputtering, etc.

If the multilayer structure is used as shown above, the metal piece 29.29' will be the flocked 2
6.26', and when the flocked hair 26.26' is charged with static electricity and becomes a high potential, these flocked hair 26.26' and the metal pieces 29, 29' become poles, causing an air discharge, commonly known as corona discharge. to lower the potential and lose static electricity. In this state, the dust attached to the flocked hair 26, 26' is removed from the restraint of static electricity and is removed by the intake air, thereby preventing the dust from adhering.

In this way, the present invention is an epoch-making method in that it can solve all problems in using a vacuum cleaner at once with an extremely simple structure in which metal pieces 29 and 29' are attached to the rotating brush 8 of the conventional suction device 1 with a rotating brush. It is something that brings about an effect.

Claims (1)

[Claims] When used as a suction attachment for a vacuum cleaner and connected to the vacuum cleaner, the rotary brush built into it causes the suction airflow generated by the suction action of the vacuum cleaner to collide with the fan also built in, causing the fan to rotate. In a device that rotates this rotating brush by stretching a belt from its axis to the axis of the rotating brush, the bristles planted on the brush stand rub against the surface of the object to be cleaned, such as a carpet, and stick to it. When removing the dust generated by the flocked hair, a metal piece is installed near the flocked hair, or the brush stand on which the flocked hair is planted is covered with a metal film, and the flocked hair and the metal piece are used as two poles to collect the so-called corona. A suction tool for vacuum cleaners with a rotating brush that erases by causing electrical discharge.
