No.9011 BTJD-II Concave-convex surface dust footprint collecting device

No.9011 BTJD-II Concave-convex surface dust footprint collecting device

Purpose
Lift a single footprint, a trail of footprints or various dust prints on an irregular surface, vertical surface, flat surface, soft surface and hard surface.

Content

Composition
The lifter is mainly composed of three parts: handle, base plate and sponge. The high voltage generator, battery, voltage regulator and cathode socket are mounted on two ends of the handle; the handle is mounted on the base plate; the sponge is under the base plate, and the anode spring passes through the sponge. The sturdy structure can withstand the full weight of the human body.

Features
A. Equipped with rechargeable battery; push the switch forward, the indicator lights up, and the lifter is turned on. At this time, the anode and cathode sockets of the spring carry high-voltage static electricity.
B. Turn the voltage knob to adjust the output voltage between 14KV and 30KV. If the dust is thick, a low voltage should be applied; if the dust is thin, a high voltage should be applied.
C. When the battery is exhausted, plug the power adapter into the 5V external power socket to achieve AC supply.
D. When the battery is exhausted, plug the charger into the charging socket; the red light of the charger indicates "charging" and the green light indicates "full charge".
E. Equipped with ground wire extension. If the indoor floor is insulated, the grounding wire can be extended to the outside with the ground wire extension.
 

Specification

Lift dust print on the irregular surface
Adhere the lifting film to the nylon adhesive on both ends of the base plate to make the lifting film wrap the sponge. Plug one end of the ground wire into the cathode socket of the lifter and place the grounding probe of the ground wire on the conductive ground. Hold the lifter and move it so that the lifting film covers the dust print on the irregular surface. Press the handle firmly to deform the sponge with the surface, so that the lifting film can completely connect the footprint; then turn the power on, the positive charges are transmitted to the lifting film through the spring electrode in the sponge and the negative charges flow into the earth through the ground wire. The static charges flowing into the lifting film generate an electric field that adsorbs the dust footprints to the lifting film.
If the ground is an insulating material such as wooden floor or plastic floor, the negative charges cannot be discharged into the earth and the positive charges cannot flow into the lifting film in a sufficient amount, then the lifting film cannot be unfolded, nor can it generate sufficient adsorption force for the dust. To solve this problem, plug one end of the ground wire extension into the cathode jack, and connect the other end to the ground wire. Place the grounding probe of the ground wire on the conductive floor outside the room, or connect it to the heating pipe, water pipe or other conductors. In this way, when the lifter is turned on, the negative charges can smoothly flow into the earth, and the positive charges can flow into the lifting film sufficiently.

Lift dust print on the wall
Adhere the lifting film to the nylon adhesive on both ends of the base plate to make the lifting film wrap the sponge. Plug one end of the ground wire into the cathode socket of the lifter and place the grounding probe of the ground wire on the conductive ground. Hold the lifter and move it so that the lifting film covers the dust print on the wall. Press the handle firmly to compress the sponge, so that the lifting film adhere to the footprint closely. Turn the power on, the positive charges are transmitted to the lifting film through the spring electrode in the sponge and the negative charges flow into the earth through the ground wire. The static charges flowing into the lifting film generate an electric field that adsorbs the dust footprints to the lifting film.

Lift a single footprint on a soft surface
Place the lifting mat on the dust print, cover the lifting mat with the sponge, and press the handle firmly to attach the lifting mat to the soft surface closely. Plug the ground wire into the cathode socket and place the grounding probe on the conductive ground. Turn the power on, the positive charges are transmitted to the lifting mat through the spring electrode in the sponge and the negative charges flow into the earth through the ground wire. The static charges flowing into the lifting mat generate an electric field that adsorbs the dust footprints to the lifting mat.

Lift a single footprint on a hard surface
Adhere the lifting film to the nylon adhesive on both ends of the base plate to make the lifting film wrap the sponge. Plug one end of the ground wire into the high-voltage cathode socket and place the grounding probe of the ground wire on the conductive ground. Hold the lifter and move it so that the lifting film covers the dust print on the ground. Turn the power on, the positive charges are transmitted to the lifting film through the spring electrode in the sponge and the negative charges flow into the earth through the ground wire. The static charges flowing into the lifting film generate an electric field that adsorbs the dust footprints to the lifting film.

Lift a trail of footprints on a hard surface
Place the lifting film roll close to one end of the footprint and press the anode spring of the lifter on the lifting film. Plug one end of the ground wire into the high-voltage cathode socket and place the grounding probe of the ground wire on the conductive ground. Turn the power on, the positive charges are transmitted to the lifting film through the anode spring and the negative charges flow into the earth through the ground wire. Like charges repel each other, therefore, the lifting film roll will unfold automatically and cover the footprints. The static charges flowing into the lifting film generate an electric field that adsorbs the dust footprints to the lifting film.

If the ground is an insulating material such as wooden floor or plastic floor, the negative charges cannot be discharged into the earth and the positive charges cannot flow into the lifting film in a sufficient amount, then the lifting film cannot be unfolded, nor can it generate sufficient adsorption force for the dust. To solve this problem, plug one end of the ground wire extension into the cathode jack, and connect the other end to the ground wire. Place the grounding probe of the ground wire on the conductive floor outside the room, or connect it to the heating pipe, water pipe or other conductors. In this way, when the lifter is turned on, the negative charges can smoothly flow into the earth, and the positive charges can flow into the lifting film sufficiently.
