[0053] Base;

[0054] Friction test bar;

[0055] The container is located on the base and has an opening at the top for the friction test bar to enter and exit.

[0056] Adsorbed spheres, multiple in number, located in a container;

[0057] A fabric support plate is placed on the base, and the fabric is placed on it.

[0058] This utility model discloses a fabric electrostatic property demonstration device, which includes a base, a friction test bar, a container, adsorption balls, and a fabric support plate. In use, the friction test bar is rubbed (usually fully rubbed) against the fabric support plate and then inserted into the container. The adsorption balls will be adsorbed onto the friction test bar. The amount of static electricity generated after the friction test bar is rubbed with different fabrics is different, and the number of adsorption balls is also different, thus allowing for a direct demonstration of the differences in electrostatic properties of different fabrics.

[0059] Example 1

[0060] See Figures 1 to 3 The fabric electrostatic properties demonstration device of Embodiment 1 of this utility model includes:

[0061] Base 1;

[0062] Friction test rod 2;

[0063] Container 3 is placed on base 1 and has an opening at the top for the friction test rod 2 to enter and exit.

[0064] Adsorbed spheres 4, there are multiple of them and they are located in container 3;

[0065] Fabric support plate 5 is placed on base 1, and fabric is placed on it.

[0066] See Figure 3 In this embodiment, the friction test rod 2 includes a handle portion 21 and a friction portion 22, wherein the diameter of the handle portion 21 is larger than that of the friction portion 22. The handle portion 21 is made of plastic, and the friction portion 22 is made of acrylic.

[0067] In this embodiment, the upper end of the container 3 is opened to form an opening. The diameter of the opening is smaller than the diameter of the handle portion 21 of the friction test rod 2, but larger than the diameter of the friction portion 22 of the friction test rod 2.

[0068] In this embodiment, the friction part 22 includes a cylindrical part and a groove 221 formed on the cylindrical part. The groove 221 can increase the amount of static electricity generated by friction. In other embodiments, the friction part 22 includes a cylindrical part and a protruding rib extending from the cylindrical part.

[0069] In this embodiment, the adsorption ball 4 is made of foam plastic.

[0070] In this embodiment, the fabric electrostatic properties demonstration device also includes a support mechanism 6, and the fabric support plate 5 is disposed on the support mechanism 6.

[0071] In this embodiment, the upper part of the support mechanism 6 is rotatably connected to the fabric support plate 5, and the lower part of the support mechanism 6 is rotatably connected to the fabric support plate 5.

[0072] In this embodiment, the support mechanism 6 includes a first connecting member 61 fixedly connected to the base 1, a second connecting member 62 fixedly connected to the fabric support plate 5, and an intermediate support rod 63 whose two ends are respectively rotatably connected to the first connecting member 61 and the second connecting member 62. By rotating the fabric support plate 5 or rotating the intermediate support rod 63 of the support mechanism 6, the angle and position of the fabric support plate 5 can be adjusted to accommodate the gripping habits of different people (such as adapting to different heights).

[0073] In this embodiment, there are at least two fabric support plates 5, each holding two different fabrics. The fabric electrostatic property demonstration device also includes a fabric material indicator 84. The at least two fabric support plates 5 are distributed horizontally. The two fabric support plates 5 are offset slightly from each other. For example, the left fabric support plate 5, closer to the container 3, holds a fabric that is less prone to generating static electricity, while the right fabric support plate 5, farther from the container 3, holds a fabric that is prone to generating static electricity. The fabric material indicator 84 is located in front of the corresponding fabric support plate 5.

[0074] In other embodiments, container 3 is transparent to facilitate observation of the conditions inside container 3.

[0075] In this embodiment, the lower end of the container 3 is open, and a circular component is fixed on the base 1, with the container 3 covering the circular component.

[0076] In this embodiment, the fabric and the fabric support plate 5 can be fixed by means of adhesive, clamping, Velcro, etc.

[0077] The beneficial effects of the fabric electrostatic property demonstration device of Embodiment 1 of this utility model are as follows: In use, the friction test rod 2 is rubbed (usually fully rubbed) with the fabric on the fabric support plate 5 and then inserted into the container 3. The adsorption balls 4 will be adsorbed on the friction part 22 of the friction test rod 2. The amount of static electricity generated by the friction test rod 2 after rubbing with different fabrics is different, and the number of adsorbed balls 4 is also different, so as to intuitively demonstrate the differences in electrostatic properties of different fabrics; there are at least two fabric support plates 5, and two different fabrics are fixed to them respectively, so as to facilitate operation and comparison; the support mechanism 6 includes a first connecting piece 61 fixed to the base 1, a second connecting piece 62 fixed to the fabric support plate 5, and an intermediate support rod 63 whose two ends are rotatably connected to the first connecting piece 61 and the second connecting piece 62 respectively. The angle and position of the fabric support plate 5 are adjustable and have good adaptability.

[0078] Example 2

[0079] The main difference between Example 2 and Example 1 is that some additional components have been added.

[0080] See Figure 4 In this embodiment, the fabric electrostatic property demonstration device also includes a limiting member 7 fixed on the base 1. The limiting member 7 has a positioning hole, and the container 3 is located in the positioning hole. The lower end of the container 3 can be open (without a bottom wall) or closed (with a bottom wall). The upper surface of the limiting member 7 is inclined and is lower in the front and higher in the back.

[0081] In this embodiment, the fabric electrostatic properties demonstration device also includes a logo display board 81, a QR code display board 82, and a slogan display board 83, which are located on the base 1. The slogan display board 83 is located behind the fabric support plate 5.

[0082] Example 3

[0083] The main difference between Example 3 and Example 1 is that a folded funnel 9 is added.

[0084] See Figure 5 and Figure 6 In this embodiment, the fabric electrostatic properties demonstration device also includes a folded funnel 9, the smaller diameter of which is smaller than the opening of the container 3.

[0085] In this embodiment, the folding funnel 9 can be purchased commercially. The folding funnel 9 can be used to contain the adsorbent balls 4 that fall from the friction test rod 2. In use, the folding funnel 9 can be unfolded and inserted into the opening of the container 3. Then, the lower end of the friction test rod 2 with the adsorbent balls 4 adsorbed can be placed into the folding funnel 9. The adsorbent balls 4 on the friction test rod 2 can be made to fall into the folding funnel 9 by scraping or using an electrostatic eliminator, and finally return to the container 3.

[0086] In other embodiments, the opening of container 3 can also be configured as a funnel shape, thus eliminating the need for a separate funnel.

[0087] Example 4

[0088] The main difference between Example 4 and Example 2 is that a small ball separation component is added.

[0089] See Figures 7 to 9 In this embodiment, the fabric electrostatic properties demonstration device also includes a ball separation component, which includes a sliding ring 13 sleeved on the friction part 22.

[0090] In this embodiment, the sliding ring 13 is fixed to the friction test rod 2 by the first magnetic suction member 11 and the second magnetic suction member 12. The first magnetic suction member 11 is fixed to the friction test rod 2, and the second magnetic suction member 12 is fixed to the sliding ring 13 (upper surface). When it is not necessary to clean the adsorbed balls 4, the sliding ring 13 is fixed to the friction test rod 2 by the magnetic force between the first magnetic suction member 11 and the second magnetic suction member 12.

[0091] In this embodiment, the ball separation assembly also includes an elastic pad 15 disposed radially inside the sliding ring 13. The main function of the elastic pad 15 is to prevent the sliding ring 13 from scratching the acrylic friction part 22, thereby reducing the wear of the friction part 22 (the sliding ring 13 is usually made of a hard conductive material). The elastic pad 15 also prevents the sliding ring 13 from separating from the friction test rod 2 due to gravity. The elastic pad 15 can be made of a conductive material (such as a conductive sponge) to clean the adsorbed balls 4 while eliminating static electricity on the friction test rod 2.

[0092] In this embodiment, the ball separation assembly further includes a covering fabric 14 disposed radially inside the sliding ring 13. The covering fabric 14 contacts the foam balls and scrapes them off. The covering fabric 14 covers the elastic pad 15 and is fixedly connected to the sliding ring 13, specifically by means of adhesion or other methods.

[0093] In this embodiment, the covering fabric 14 has antistatic properties, which is used to clean the small balls while eliminating static electricity on the friction part 22.

[0094] In this embodiment, the sliding ring 13 has an operating lug for easy operation.

[0095] In this embodiment, the sliding ring 13 is conductive, thereby releasing the static electricity accumulated in the friction part 22 of the friction test rod 2 through the covering cloth 14, the sliding ring 13 and the human body (or via the covering cloth 14, the elastic pad 15 and the sliding ring 13).

[0096] See Figure 10 In this embodiment, the upper surface of container 3 is funnel-shaped (conical).

[0097] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments.
