Description

  The present invention relates to a vacuum suction hose having a brush and an ion generator at the tip.

  Conventionally, a vacuum suction hose having a brush at the tip is used, and dust is sucked and removed by vacuum while rubbing an object to which dust is attached with a brush.

  However, in the conventional example, there is a problem in that dust is adhered by conversely because static electricity is generated because the object to which dust adheres is rubbed with a brush at the tip.

  Therefore, the purpose of the present invention is equipped with an ion generator at the tip of the vacuum suction hose so that static electricity does not occur even when scraping dust with a brush, and static electricity is removed even after the dust removal operation is completed. An object of the present invention is to provide a vacuum suction hose that can efficiently perform static elimination and dust removal without sucking dust floating from the surroundings.

  The vacuum suction hose of the present invention has a vacuum suction hose body, a brush having bristles attached to the tip of the vacuum suction hose body, and at least one ion generator arranged adjacent to the bristles of the brush. It is characterized by. The ion generator is preferably located near the tip of the brush and outside or inside the hose, and the voltage applied to the ion generator is preferably direct current or pulse. And the bristles are preferably held in a tape shape and are preferably wrapped around the outside of the tip of the brush, and the bristles are held in a semicircular or semi-elliptical shape in groups, The bristles are preferably assembled outside the brush tip, and the bristles are preferably detachably attached to the outside of the brush tip by velcro, and the bristles implanted in the brush have a dense root and a loose tip. It is preferable.

  According to the present invention, since the ion generating device is provided at the tip of the vacuum suction hose, static electricity is prevented from being generated even when the dust is scraped off with a brush, and the static electricity is removed even after the dust removal operation is completed. Without attracting dust floating from the surroundings, it is possible to contribute to efficiently performing static elimination and dust removal work.

  The vacuum suction hose of the present invention includes a vacuum suction hose body, a brush having bristles attached to the tip of the vacuum suction hose body, and at least one ion generator disposed adjacent to the bristles of the brush. .

Example 1
Next, Embodiment 1 of the present invention will be described with reference to FIG. FIG. 1 is a view for explaining the present invention, FIG. 1a is a front view, and FIG. 1b is a bottom view.

  In the first embodiment, the vacuum suction hose 10 has a vacuum suction hose main body 12 and bristles 16 held in front of the vacuum suction hose main body 12 arranged in a ring shape such as a circle or an ellipse, for example. And an ion generator main body (ionizer) 18, and four ion generators 20 for generating ions for discharging the dust by the ion generator main body (ionizer) 18. The ion generator 20 has a ring-like arrangement at the tip of the brush 14. The bristles (hereinafter, bristles in a ring-like arrangement are simply referred to as bristles) 16 are inside the bristles 16. The brush 14 has a suction port (not shown in this drawing) adjacent to the bristles 16 and communicating with the vacuum suction hose body 12.

  The voltage applied to the ion generator is preferably direct current or pulse. When the voltage applied to the ion generator is DC, the + ion generator and the − ion generator form one set, and two sets of ion generators are provided. The ionizer that supplies a high voltage to the ion generator may be configured separately from the vacuum suction hose body in order to lighten the vacuum suction hose body and improve workability. In order to do so, it may be configured integrally. In addition, the polarity of an adjacent ion generator is comprised by the reverse polarity.

  Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a view for explaining the present invention, FIG. 2a is a front view, and FIG. 2b is a bottom view.

  In the second embodiment, the vacuum suction hose 10 has a vacuum suction hose body 12 and bristles 16 that are held in front of the vacuum suction hose body 12 and arranged in a ring shape such as a circle or an ellipse, for example. And an ion generator main body (ionizer) 18, and four ion generators 20 for generating ions for discharging dust from the ion generator main body (ionizer) 18. 16 and near the bristles 16. The brush 14 has a suction port (not shown in this drawing) adjacent to the bristles 16 and communicating with the vacuum suction hose body 12.

  The voltage applied to the ion generator is preferably direct current or pulse. When the voltage applied to the ion generator is DC, the + ion generator and the − ion generator form one set, and two sets of ion generators are provided. Also, the ionizer that supplies high voltage to the ion generator may be configured separately from the vacuum suction hose to lighten the vacuum suction hose and improve workability. However, to simplify the ionizer configuration You may comprise integrally. In addition, the polarity of an adjacent ion generator is comprised by the reverse polarity.

  FIG. 3 is a diagram for describing the relationship between the distances between the ion generators when the voltage applied to the ion generator is a direct current. FIG. 3a shows a case where there are two ion generators. FIG. The distance A is smaller than the distance B in the vertical direction. FIG. 3b shows the case where distance A and distance B are approximately equal.

  It is preferable that the polarity of the adjacent ion generator 20 is reverse. In this case, the generated ions attract each other and attract closer as they are closer. Therefore, as shown in FIG. 3a, if the distance A is small, the ions are strongly attracted between A, the attracting between B is lost, and there is little or no ions between B. For this reason, the winds X and X 'blowing through between A include ions and perform neutralization, but the winds Y and Y' blowing through between B do not include ions and thus do not perform neutralization. In this way, the static elimination action varies depending on the direction. On the other hand, as shown in FIG. 3b, if A and B are substantially equal, X, X ', Y, and Y' contain substantially the same ions and the charge eliminating action is the same, so the charge eliminating action does not differ depending on the direction.

  FIG. 4 shows a method for supporting the ion generator. When two or more sets of ion generators are provided, one + ion generator and one − ion generator are connected by the support 22, and are in contact with and supported by the brush 14 only at the midpoint of the support 22. If the absolute values of the + high voltage and − high voltage of the ion generator are substantially equal, the intermediate point of the support 22 has an electrostatic potential of approximately 0 V, and the brush 16 is supported by contacting the brush 14 at this point. It becomes difficult for current to flow between the bodies 22. That is, no leakage occurs. In particular, it is effective when the brush 16 is formed of a conductor such as metal.

  FIG. 5 shows an embodiment using the supporting method. FIG. 5a shows a front view of an elongated round brush, and FIG. 5b shows a bottom view. FIG. 5c shows a bottom view as an example of a round brush. The ion generators 20 are not in direct contact with the brush 14, but are in contact with the brush 14 when the electrostatic potential at the intermediate point is approximately 0 V by the support 22. Therefore, it is difficult for electric leakage to occur. This is particularly effective when the brush 14 is a conductor.
