Embodiment 1

[0029] Please refer to figure 1 , shows a schematic structural view of the filter segment 1 in the filter component of a tobacco product provided by Embodiment 1 of the present invention. It should be noted that in the drawings of this embodiment, unnecessary components are simplified, such as filter components wrapping layer in . However, it is understandable that in figure 1 The outer surface of the shown filter section 1 is covered with a cylindrical wrapping layer, so that at least part of the outer surface of the filter section 1 is closely attached to the inner cavity of the cylindrical wrapping layer, and the Venturi-type filter provided by the application can be formed. Filter components for tobacco products.

[0030] like figure 1 As shown, the outer peripheral surface of the cylindrical filter section 1 is provided with an axially through groove, wherein the groove width of the groove first shrinks and then expands gradually along the preset airflow direction; the...

Embodiment 2

[0046] The present invention also provides a tobacco product, which comprises the above-mentioned filter component and any one or more smoke generating devices.

[0047] In this embodiment, the above-mentioned smoke generating device may be a traditional combustion-type cigarette product, or a new type of heat-not-burn tobacco product or an e-cigarette oil heating device, which is not specifically limited in this application.

[0048] In the tobacco product provided in this application, through the Venturi channel provided on the filter part, after the smoke is injected into the filter part, the Venturi channel guides the smoke forcibly, so that the heat energy of the smoke is further converted The mechanical energy required for gas flow achieves the purpose of active cooling, thereby reducing the temperature of the flue gas flowing out of the air outlet, and improving the taste of consumers. At the same time, because the above-mentioned Venturi channels in this embodiment are...

Abstract

The invention provides a filtering component of a tobacco product and the tobacco product. The filtering component comprises a cylindrical wrapping layer and a cylindrical filtering section arranged in a cavity of the cylindrical wrapping layer, wherein the outer peripheral surface of the filtering section is provided with an axially through groove, and the groove width of the groove is set to shrink first and then expand gradually along the preset airflow direction; the wrapping layer is tightly attached to at least part of the peripheral surface of the filtering section, and the wrapping layer and the groove are combined to form a Venturi channel. By utilizing the filtering component, the smoke can generate a Venturi effect in the filtering component, so that the temperature of the smokeis reduced, and the smoking experience of consumers is improved.

Description

technical field [0001] The invention belongs to the field of tobacco products, and in particular relates to a filter part of tobacco products and tobacco products. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] At present, with the emergence and continuous development of heat-not-burn technology, the structure of filter components in existing traditional cigarette products cannot meet the experience requirements of consumers, and the demand for improvement of filter components of tobacco products is gradually increasing. The reason is that when the traditional filter rod is applied to the heat-not-burn device for filtration, there will be many problems such as inconsistent smoke and high inlet temperature, which greatly affects the smoking experience of consumers. Con...
