Description

  The present invention relates to a static eliminator set including a static eliminator and a support base thereof, and in particular, the static eliminator can be carried alone and used (portable use), and the static eliminator is fixed to a support base and used ( The present invention relates to a static eliminator set that can also be used.

  Conventionally, various static eliminators have been developed in order to reduce static electricity of static elimination objects. For example, in a corona discharge type static eliminator, by applying a voltage to a needle-like ion generation electrode, an electric field concentrates on the needle end of the ion generation electrode, and corona discharge is generated at the needle end. As a result, ions are generated from the needle end of the ion generating electrode. The ions generated in this manner are blown as ion-containing air and sprayed onto the static elimination object, thereby neutralizing and reducing static electricity of the static elimination object (see, for example, Patent Document 1).

The static eliminator is roughly classified into a type to be carried and used and a type to be installed and used, and has an outer shape suitable for each usage situation. For example, many static eliminators for portable use have a shape having a gripping part such as an air gun so that it can be easily held by hand. Moreover, many static eliminators used for installation are equipped with a stand that supports the static eliminator body during installation. Therefore, an easy-to-use type static eliminator is selected and used according to the state of the static elimination object and the purpose of static elimination.

  By the way, static electricity may be a problem when measuring the weight of a powdered sample using a balance equipped with a weighing chamber. Problems with static electricity include “weighing error” and “adhesion”. For example, when measuring a weight by putting a powdered sample into a beaker's tare, the sample or beaker's tare is electrostatically charged and attracts or repels the windshield near the weighing pan. Occurs by mating. Further, the problem of adhesion due to static electricity occurs when the user takes a sample, for example, the sample is scattered around by static electricity, or the sample adheres to the measuring spoon, thereby hindering measurement. In addition, when a sample once weighed is transferred to a test tube or the like, the sample adheres to the wall surface of the test tube or the like due to static electricity, which causes an error in the analysis result.

For this reason, it is necessary to neutralize the tare and sample of the beaker. In this case, the use of an installation type static eliminator is advantageous in that other samples can be measured during static elimination.
In addition, when a windshield glass is provided on the balance, if dust is generated in the windshield glass, surrounding dust or the like may adhere. The dust adhering to the windshield then leaves the windshield and rests on the weighing pan, which may cause a measurement error. For this reason, it is necessary to neutralize the windshield itself. In this case, it is more convenient to use a portable static eliminator to neutralize the windshield (the entire balance).

  As described above, depending on the static elimination object and the static elimination purpose, there are cases where both installation and portable use are desired. In the conventional static eliminator, since the stationary use type and the portable usage type are clearly separated, there is no static eliminator suitable for use in both the stationary usage and the portable usage.

Therefore, an object of the present invention is to provide a static eliminator set that can be easily carried out for both portable use and installation use.
Another object of the present invention is to provide a static eliminator set that can easily position the static eliminator with respect to the support base when the static eliminator is set on the support base used during installation and use.
Another object of the present invention is to provide a static eliminator set that can be attached to and detached from a support base used at the time of installation and use with one touch, and that does not require a screwing operation or the like.

  The static eliminator set of the present invention made to solve the above problems is provided with an ion generation mechanism in the box and an emission port (ion emission part) for discharging ion-containing air on the surface of the box. A static eliminator that the user can use with the box facing the discharge target, and the front surface of the box body, the rear surface of the box body, and the lower surface of the box body. A static eliminator set comprising a pedestal on which a front support, a rear support, and a lower support that are in contact with a part of each surface are formed, and a support that includes a leg that fixes and supports the pedestal. And the front surface of the box body of the static eliminator is formed by a step formed at a boundary between a reference surface and a protruding surface protruding forward from the reference surface, or a reference surface and an embedded surface embedded behind the reference surface, and Provided with a V-shaped stepped portion that tapers downward A concave portion is formed on the rear surface of the box body of the static eliminator, and a V-shaped step portion that supports the V-shaped step portion when the static eliminator is placed on the front support body on the base of the support base. A receiving part is formed, and when the static eliminator is placed, the rear support in the pedestal of the support pedestal energizes the box of the static eliminator forward and is fitted into a recess on the rear face of the box. An urging member is attached.

Here, the outer shape of the box body of the static eliminator has three surfaces: a box front surface, a box rear surface facing the box front surface, and a box body lower surface connecting these two surfaces below the box front surface and the box rear surface. If it is the box shape which has, it will not specifically limit. Specifically, a rectangular parallelepiped shape or a shape obtained by deforming a part thereof is preferable.
Moreover, if it is comprised so that ion-containing air may be blown out from a discharge port, it will not specifically limit.

According to the present invention, the static eliminator set includes a static eliminator that is a portable box and a support base that supports the box, and when the portable is used, the static eliminator is used alone for installation. In some cases, use the static eliminator fixed on the support base.
When using the static eliminator fixed to the support base, first check the front of the box, the rear of the box, and the bottom of the box with reference to the sharp V-shaped direction of the V-shaped step on the front of the box. Subsequently, the V-shaped stepped portion is held so that the V-shape of the V-shaped stepped portion is located above the V-shaped stepped receiving portion provided on the front support of the pedestal, and the box is moved downward therefrom. At this time, since the urging member attached to the rear support of the pedestal urges the box forward, the front support of the pedestal and the front of the box come into contact with each other. As the box moves downward, the V-shaped stepped portion is guided to the V-shaped wall of the V-shaped stepped receiving portion, and finally the V-shaped pointed portion of the V-shaped stepped portion becomes the V-shaped stepped receiving portion. It reaches the V-shaped valley bottom position of the part and is supported stably. At the same time, the urging member is inserted into the recess on the rear surface of the box, and the box and the support base are fixed.

  According to the static eliminator set of the present invention, it can be easily carried out for both portable use and installation use. Further, according to the present invention, when the static eliminator is set on the support base used at the time of installation, the static eliminator is easily positioned with respect to the support base by the guide operation by the V-shaped step portion and the V-shaped step receiving portion. be able to. In addition, according to the present invention, it is possible to attach and detach the support base used at the time of installation and use with a single touch, and it is possible to eliminate complicated work such as screwing work.

(Means and effects for solving other problems)
In the above invention, the support base may further include a base adjustment mechanism that adjusts a fixed angle of the base when the base is fixedly supported on the leg portion.
By adjusting the fixed angle of the pedestal with the pedestal adjusting mechanism, the direction of the discharge port can be directed in an arbitrary direction, and the usability during installation and use can be improved.

In the above invention, at least two recesses formed on the rear surface of the box of the static eliminator may be formed at positions separated from each other.
When fixed at one recess, if the angle of the pedestal is extremely inclined, the static eliminator may rotate and fall off around the fixed recess due to the moment of force. By being fixed at more than one place, it is not rotated and can be supported more stably.

Moreover, in the said invention, you may make it form the discharge port which discharge | releases ion-containing air in the direction where the V-shaped pointed direction of the V-shaped level | step-difference part faces.
Thereby, by confirming the direction of the V shape, it is possible to confirm the blowing direction of ions at a glance.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments described below, and it goes without saying that various aspects are included without departing from the spirit of the present invention.
FIG. 10 is a diagram illustrating the overall structure of the static eliminator set. The static eliminator set 100 of the present invention includes a rectangular parallelepiped static eliminator 6 having a discharge port 6d on the lower surface of the box, and a support base 20 that fixes the static eliminator 6.

First, the static eliminator 6 according to the present invention will be described. FIG. 1 is a plan view showing a static eliminator according to the present invention, FIG. 2 is a front view showing the static eliminator according to the present invention, and FIG. 3 is a bottom view showing the static eliminator according to the present invention. 4 is a rear view showing the static eliminator according to the present invention, FIG. 5 is a side view showing the static eliminator according to the present invention, and FIG. 6 is an AA line of the static eliminator shown in FIG.

And a discharge port 6d. The static eliminator 6 has a rectangular parallelepiped shape that can be easily held by hand, and is covered with a box upper surface 13, a box front surface 10, a box lower surface 11, a box rear surface 12, and two box side surfaces. It has been broken.

  The fan (blower mechanism) 7 is for making an air flow. When the fan 7 rotates, an air flow is generated from the intake port 6c to the discharge port 6d.

The air inlet 6c is disposed on the box upper surface 13 of the static eliminator 6, and is, for example, a square-shaped opening of about 30 mm square in plan view, and a dust removal filter (not shown) is installed in the opening. ing.
The discharge port 6d is disposed on the box lower surface 11 of the static eliminator 6, and is, for example, a square-shaped opening of about 30 mm square in plan view, and ion-containing air containing positive ions and negative ions is unidirectional (opening surface). (In a direction perpendicular to the direction).

The high voltage generator 1 boosts an input voltage applied between a + input lead wire (not shown) and a − input lead wire (not shown) with a piezoelectric transformer (not shown) to make an alternating current. Output.
The high-voltage generator 1 has an output voltage adjusting unit (not shown), and the amount of ions generated is 100,000 by controlling the output voltage applied to the ion generating electrode 2. It can be varied in the range of cm ^{3 to} 1 million pieces / cm ³ .

The ion generating electrode 2 is, for example, formed as a needle-like electrode by processing a metal plate having a thickness of about 0.1 mm to form a needle end that faces the discharge port 6d. When an alternating voltage is applied to the needle-like electrode through the high voltage output line 5, negative ions and positive ions are generated alternately.
The ground electrode 3 is a needle-like electrode in which, for example, a metal plate having a thickness of about 0.1 mm is processed to form a needle end and this is directed toward the discharge port 6d.
The ion generating electrode 2 and the ground electrode 3 are disposed between the intake port 6 c and the discharge port 6 d and are disposed downstream of the fan 7. Ion-containing air is discharged from the outlet 6d.

The V-shaped stepped portion 10a is formed by a step generated at the boundary between the reference surface 10s and the protruding surface 10t protruding forward from the reference surface, and is formed to taper downward. Thereby, when fixing the static eliminator 6 and the support base 20, the attachment method can be confirmed by looking at the sharp V-shaped direction of the V-shaped stepped portion 10a. Further, the V-shaped stepped portion 10a is held so as to be above a V-shaped stepped receiving portion 22f of the support base 20 described later, and from there, the static eliminator 6 is moved downward. The static eliminator 6 and the support base 20 can be accurately aligned by the guidance operation performed when the character step portion 10a contacts the V-shaped step receiving portion 22f.
The step is about 2 mm, and is engaged with the V-shaped step receiving portion 22f.

Two concave portions 12a and 12b are formed on the rear surface 12 of the box. The inner bottoms of these recesses 12a and 12b are V-shaped. The distance between the recess 12a and the recess 12b is, for example, about 40 mm. As a result, when the static eliminator 6 and the support base 20 are fixed, the two concave portions 12a and 12b are respectively fitted with two convex portions 21a and 21b of a leaf spring (biasing member) 21 of the support base 20 described later. In other words, the leaf spring 21 urges the static eliminator 6 forward, so that the static eliminator 6 and the support base 20 are fixed with a spring force having an appropriate strength.

The leaf spring 21 has a left upper portion and a right upper portion fixed to the rear surface of a rear support 22b of a pedestal 22, which will be described later, with screws 21c. Accordingly, the left lower end, the right lower end, and the connecting portion can be moved in the front-rear direction with the left upper portion and the right upper portion as axes.
Further, when viewed from the side, the convex portions 21a and 21b have a "<" shape, and when a force is applied from above and below, the lower end portion of the left portion, the lower end portion of the right portion, and the connecting portion can be easily formed. Can be moved backwards.

The pedestal 22 includes a front support 22 a that contacts the box front surface 10 of the static eliminator 6, a lower surface support 22 d that contacts the box lower surface 11 of the static eliminator 6, and a rear surface that contacts the box rear surface 12 of the static eliminator 6. It consists of the support body 22b, the protection part 22c, and the side surface support body 22e, and when it sees from the side, it is made into the horizontal Y-shape. The front support 22a has a V-shaped step receiving portion 22f when viewed from the front. In addition, the leaf spring 21 is fixed with screws 21c at the upper portion of the rear surface of the rear support 22b, and the two protrusions 21a and 21b of the leaf spring 21 are respectively provided from the rear surface to the front surface at the lower portion of the rear surface support 22b. It has two rectangular through holes for penetration. Further, the rear support 22b and the protection 22c are spaced apart so as not to prevent the left and lower ends of the leaf spring 21 from moving in the front-rear direction. . And the screw part 24a of the base adjustment mechanism 24 is being fixed to the side surface support body 22e.
