Imprinting device suitable for cigarette heating airflow regulation and control

Abstract

An impressing device suitable for cigarette heating airflow regulation and control is a device used for impressing grooves in the peripheral wall of a heated cigarette to improve ventilation, the impressing device is a sleeve with the inner wall provided with axial strip-shaped protrusions, one end of the sleeve is open, the other end of the sleeve is closed, and the inner diameter of the sleeve is gradually reduced inwards from the open end to be slightly larger than the outer diameter of the cigarette and then kept constant. The constant section is slightly longer than the tobacco filling section; the strip-shaped protrusion extends from the position where the inner diameter of the sleeve is not changed to the closed section, the protrusion height at the starting position is 0, and the protrusion height is gradually and smoothly increased to a certain value and then keeps unchanged. When the device is used, a tobacco end is inserted into the sleeve and is drawn out after being kept for a period of time, namely a plurality of grooves beneficial for airflow to pass through are embossed. The cigarette heating device has the functions that the using effect of a heating cigarette on a smoking set without an air guide groove can be optimized, the air flow is increased, and the suction resistance is reduced; the variable-diameter design of the sleeve facilitates insertion; the strip-shaped protrusions are designed without edges and corners, and the cigarettes cannot be scratched in the using process.

Description

Technical Field

[0001] The utility model belongs to the field of novel tobacco products, in particular to an imprinting device suitable for regulating airflow of heated cigarettes. Background Art

[0002] In recent years, with the improvement of living standards, users have paid more attention to the health issues of tobacco products. As a new type of cigarette that has emerged in recent years, heated cigarettes have a lower tar content in the smoke than traditional cigarettes due to their non-combustion characteristics, and have less impact on health. There are many types of heated cigarettes on the market, and the technical routes are different, which leads to the poor adaptability of some smoking devices to other types of cigarettes. Chinese patent 202010241686.9 (patent granted) announced a closed heat-not-burn cigarette and assembly. This cigarette has an air inlet set on the cigarette, and there is no groove in the cigarette slot of the matching smoking device. When using this smoking device to smoke other cigarettes, the cigarette is close to the inner wall of the slot, and the air flow cannot pass through, resulting in excessive suction resistance and poor smoking experience. Utility Model Content

[0003] The purpose of the utility model is to provide an imprinting device suitable for regulating the airflow of heated cigarettes, thereby solving the problem of poor versatility of heated cigarettes.

[0004] The purpose of this utility model is achieved by adopting the following technical solutions:

[0005] The utility model is a stamping device suitable for regulating the airflow of heated cigarettes. It is a device for stamping grooves on the outer peripheral wall of heated cigarettes to improve ventilation. The stamping device is a sleeve with an inner wall provided with an axial strip protrusion. One end of the sleeve is open and the other end is closed. The inner diameter of the sleeve gradually decreases inward from the open end and remains constant after it is slightly larger than the outer diameter of the cigarette. The length of the constant inner diameter section of the sleeve is slightly larger than the length of the cigarette filling section. The strip protrusion extends from the constant inner diameter of the sleeve to the closed section, and the height of the protrusion is 0 at the beginning, gradually and smoothly increases to 1-2 mm, and then remains unchanged until the closed end.

[0006] Furthermore, the inner diameter of the sleeve is slightly larger than the outer diameter of the cigarette, with a specific value of 0.2-2 mm.

[0007] The length of the constant inner diameter section of the sleeve is slightly greater than the length of the cigarette filling section, with a specific value of 1-2 mm.

[0008] The cross section of the strip-shaped protrusion is wide at the bottom and narrow at the top, and the top is arc-shaped.

[0009] The number of the axial strip-shaped protrusions is 2-8, preferably 3-6.

[0010] To use this device, insert the tobacco end into the sleeve, hold it for a while, and then withdraw it. This creates several grooves that facilitate airflow. This utility model optimizes the use of heated cigarettes in smoking devices without air guides, increasing airflow and reducing draw resistance. The sleeve's variable diameter design facilitates insertion, and the smooth, non-angular protrusions prevent the cigarette from being scratched during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention is further described below with reference to the accompanying drawings:

[0016] like Figure 1-3 As shown: The utility model is a stamping device suitable for airflow control of heated cigarettes. It is a device for stamping grooves on the outer peripheral wall of heated cigarettes to improve ventilation. The stamping device is a sleeve 3 with a plurality of axial strip protrusions 2 (the number can be 2-8, preferably 3-6) on the inner wall. The sleeve is open at one end and closed at the other end. The inner diameter of the sleeve gradually decreases inward from the open end to a value slightly larger than the outer diameter of the cigarette (for example, 0.2-2mm) and then remains constant. The length of the constant inner diameter section of the sleeve is slightly larger than the length of the cigarette filling section (for example, 1-2mm); the strip protrusions 2 extend from the constant inner diameter of the sleeve to the closed section, and the height of the protrusions is 0 at the starting point, gradually and smoothly increases to 1-2mm, and then remains unchanged until the closed end.

[0017] The cross section of the strip-shaped protrusion is wide at the bottom and narrow at the top, and the top is arc-shaped.

[0018] When using this device, the tobacco end is inserted into the cigarette insertion cavity 1 in the sleeve, and it is kept for a period of time before being withdrawn. A number of grooves that are conducive to the passage of airflow are embossed. Its functions are: it can optimize the use effect of heated cigarettes on smoking devices without air guide grooves, increase air flow, and reduce draw resistance; the sleeve has a variable diameter design for easy insertion; the strip-shaped protrusions are designed without edges and corners, and will not scratch the cigarette during use.
