Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The subject of the disclosure is presented in the drawings, where:

[0031] FIG. 1 shows the tube with an active filter in cross-section,

[0032] FIG. 2 shows the tube of FIG. 1 in an unfolded form, also in cross-section,

[0033] FIG. 3 shows a version of the tube with an active filter in a cross-section,

[0034] FIG. 4 shows another variation of the active filter tube in cross-section.

DETAILED DESCRIPTION

[0035] FIG. 1 shows the tube with an active filter in cross section. FIG. 2 shows the same tube in an unfolded form.

[0036] The active filter tube according to the pattern includes a tube 1 (body) in which a sponge filter 4 with a density in the range of 45 to 60 PPI, a carbon filter 3, a second silver screen 2 and a first silver screen 5 are placed. user, in the pipe 1 there are successively a sponge filter 4, a carbon filter 3 located directly behind it, a second screen 2 adjacent to the carbon filter 3, a chamber 8 limited on one side by a second screen 2, and on the other hand by a first screen 5 and a chamber 9 in which the smoking material is placed, located at the other end 7 of the tube 1.

[0037] The diameter of the tube 1 is 11 mm and its length is 125 mm. The tube is made of borosilicate glass. The first silver screen 5 is placed at a distance of 20 mm from the second end 7 of the tube 1.

[0038] FIG. 3 shows another variant of the tube according to the pattern. In this variant, the tube has the same parameters and contains all the elements described in relation to the variant shown in FIGS. 1 and 2, with the difference that additionally the tube 1 is provided with an anti-skid element 10 in the form of a projection on the outer surface of the tube.

[0039] FIG. 4 shows yet another variant of the tube according to the pattern in a schematic and real view, respectively. The tube has the same parameters as shown in FIGS. 1-3, but differs from the tube of FIG. 3 in the type of anti-skid elements. In this variant, the tube comprises two such elements - respectively a widening 11 (projection) of the tube and a narrowing 12 (recess) of the tube 1, located in the area of the tube 1 between the first screen 2 and the second screen 5.
