Definitions
- the present invention relates to a filter, and more particularly to a cigarette filter. Background technique
- the existing cigarette filter is connected to one end of the cigarette, that is, the suction end, and the filter element made of the flocculent fiber material is wrapped in the wrapping paper.
- the filter element made of the flocculent fiber material is wrapped in the wrapping paper.
- the structure of the existing cigarette filter is mainly divided into two types.
- One is that the cylindrical filter element is wrapped in the wrapping paper, and one end of the filter has an interface with the cigarette.
- the disadvantage of this type of filter is that the axial length of the filter is limited by the size of the gap between the filter fibers. As the length of the filter increases, the resistance of the smoke as it passes through the filter element increases accordingly. If the length exceeds a certain length, the smoker may feel uncomfortable. Affecting the quality of cigarettes; the other is an axial through hole with different cross-sections on the filter element, such as a star, a triangle, etc., which penetrates the filter element and directly leads to the suction end of the cigarette.
- the filter of this structure generally has a long axial dimension.
- the purpose is to increase the adsorption area of the filter element to the smoke by increasing the axial size of the filter without increasing the air resistance, thereby achieving the filtering effect, and the disadvantage is that the axial length of the filter is long, and the filter is shortened. The length of the display will obviously weaken the filtering function. Therefore, the existing cigarette filter has a double contradiction between the axial length of the filter and the resistance of the flue gas, and the axial length of the filter and the filtering effect.
- An object of the present invention is to provide a filter for a cigarette which can improve the filtration effect and has a small smoke resistance, in view of the defects of the prior art filter.
- the present invention provides a filter comprising a filter element, a wrapper and an interface, the filter element having at least one spiral passage.
- the spiral channel is a filter element having a hole with a spiral groove on the wall of the hole, and the spiral groove may be single-headed or multi-headed.
- the spiral passage has at least one spiral hole extending axially along the filter element.
- the spiral passage may be through the filter element.
- the spiral channel may also be permeable to the filter.
- the spiral channels are a plurality of pieces.
- a filter of the present invention employs a technical solution having at least one spiral passage in the filter element.
- the spiral channel increases the length of the path of the smoke through the filter element, and increases the adsorption area of the filter element to a smoke. Under the action of centrifugal force, the harmful substances in the smoke can be more adsorbed on the channel wall.
- the spiral passage of the filter element of the filter of the present invention increases the length of the path of the smoke passing through the filter element and increases the adsorption area of the filter element to the harmful substances in the smoke, without increasing the air resistance.
- the purpose of improving the filtration effect of the cigarette filter is achieved.
- Figure 1 is a cross-sectional view showing a first embodiment of a filter of the present invention.
- Figure 2 is a cross-sectional view showing a second embodiment of a filter of the present invention.
- Figure 3 is a cross-sectional view showing a third embodiment of a filter of the present invention.
- Figure 4 is a cross-sectional view showing a fourth embodiment of a filter of the present invention. detailed description
- the filter comprises a filter element 1, a wrapper 2 and an interface 3, which shows that the filter element 1 of the filter has a hole 4 with a spiral groove 5 in the wall of the hole, and after the smoke enters the filter element 1 through the interface 3, along the hole 4 flowing away from the interface 3, a part of the harmful substances in the smoke is adsorbed on the wall of the hole 4 and the surface of the spiral groove 5. Since the expanded length of the spiral groove 5 is larger than the axial dimension of the filter, the filtering effect is better than the present There are technical filters.
- the filter element 1 has a spiral hole 7 extending along the axial direction of the filter element 1, and when the smoke enters the filter element 1 through the interface 3, it flows along the spiral hole 7 in a direction away from the interface 3, and a part of the smoke is harmful.
- the substance is adsorbed on the wall of the spiral hole 7, and since the expanded length of the spiral hole 7 is larger than the axial size of the filter, the filtering effect is superior to that of the prior art filter.
- Figure 3 shows a third embodiment of a filter of the invention.
- the hole 4 of the filter element 1 having the spiral groove 5 does not penetrate the filter element 1.
- a barrier layer 6 is formed between the hole 4 of the filter element 1 and the interface 3.
- the barrier layer 6 can function as existing The filtering action of the filter of the technology, and the hole 4 with the spiral groove 5 connected thereto, the secondary filtering of the smoke, so that the filtering effect is better.
- FIG. 4 shows a fourth embodiment of a filter of the present invention.
- the spiral passage has a structure in which the filter element 1 has four spiral holes 7 extending along the axial direction of the filter element 1.
- the smoke enters the filter element 1 through the interface 3, it flows through the spiral hole 7 away from the interface 3, and a part of the harmful shield in the smoke is adsorbed on the hole wall of the spiral hole 7, because the expanded length of the spiral hole 7 is larger than the filter.
- the axial size is superior to prior art filters.
