AI Technical Summary
Conventional methods like cotton swabs and rod-shaped tools fail to effectively remove paper-wrapped tobacco stick residues from the narrow gap between the inner wall and insertion port of heated tobacco devices due to insufficient penetration.
A cleaning tool with a rod-shaped base and a spiral member featuring a hollow coil structure and an ear pick-shaped tip that can securely insert into the gap, rotate to wrap around the residue, and engage with multiple points for reliable extraction.
The spiral member ensures complete removal of paper-wrapped tobacco stick residues without damaging the inner wall, maintaining stability during the extraction process.

Abstract
Description
Technical Field
[0001] The present invention relates to a cleaning tool for removing the paper-wrapped member of a tobacco stick remaining inside the insertion port of a heated tobacco.
Background Art
[0002] A heated tobacco has a structure in which a tobacco stick is inserted into an insertion port of a main body and heated. During use or after use, the tobacco stick may break, and the paper-wrapped member may adhere to or remain on the inner wall of the insertion port. Conventionally, a cotton swab, a rod-shaped tool, etc. have been used to remove such residues. However, there is a problem that the gap between the inner wall and the paper-wrapped member is narrow and it cannot sufficiently penetrate, and the residues cannot be surely removed.
Summary of the Invention
Problems to be Solved by the Invention
[0003] An object of the present invention is to surely remove the paper-wrapped member of a tobacco stick remaining inside the insertion port of a heated tobacco. Conventional cotton swabs and rod-shaped tools have a problem that the gap between the inner wall and the paper-wrapped member is narrow, so they cannot sufficiently penetrate, and the residues cannot be surely removed. The present invention aims to provide a cleaning tool that can surely penetrate into the gap, hold the paper-wrapped member, and pull it out.
Means for Solving the Problems
[0004] The cleaning tool of the present invention includes a rod-shaped base portion and a spiral member provided at the tip of the base portion. The spiral member is a hollow coil structure formed by twisting a strip-shaped metal plate in a spiral shape. The plate has a substantially mountain-shaped cross-section with a curved surface rising toward the outer peripheral side and having an acute angular ridge line that does not form a cutting edge at the top. Furthermore, the tip of the spiral member is equipped with an ear pick-shaped tip that can slip into the annular gap between the inner wall and the paper-wrapped member, and as it rotates, it enters the gap and gradually wraps around the entire circumference of the paper-wrapped member. Furthermore, the aforementioned ridge portion can be locked to the paper-wrapping member at multiple points, and while held in place by geometric constraints, it can be pulled out in a straight line. [Effects of the Invention]
[0005] According to this invention, the ear pick-shaped tip of the spiral member can be securely inserted into the annular gap between the inner wall and the paper roll member, and the paper roll member can be gradually wrapped around its entire circumference by rotation. Furthermore, the ridges formed in a roughly V-shaped cross-section engage with the paper-wrapped member at multiple points and are held in place by geometric constraints, so even a broken paper-wrapped member is less likely to loosen and can be reliably pulled out. Furthermore, because the spiral member has a hollow coil structure, it is guided while continuously contacting the inner wall of the insertion opening, allowing for stable removal work without excessively damaging the inner wall. [Brief explanation of the drawing]
[0006] [Figure 1] Figure 1 is an overall front view of the heated tobacco cleaning device according to the present invention. [Figure 2] Figure 2 is an enlarged perspective view of the spiral member. [Figure 3] Figure 3 is a view of the helical member from the axial direction. [Figure 4] Figure 4 is a transparency view showing the state in which the spiral member is inserted into the broken stick piece. [Figure 5] Figure 5 is a transparency view showing the spiral member enclosing the broken stick piece around its entire circumference. [Modes for carrying out the invention]
[0007] The embodiments of this invention will be described below with reference to the drawings. As shown in Figure 1, the heated tobacco cleaning tool (1) of the present invention comprises a base portion (3) and a spiral member (2) integrally formed at its tip. A gripping portion (4) is provided at the rear end of the base portion (3) and is configured to be rotatable. As shown in Figures 2 and 3, the helical member (2) is a hollow coil-like structure formed by twisting a strip of metal plate into a spiral shape, and has a roughly V-shaped cross section (24) that curves upward toward the outer circumference and has sharp ridges at the top that do not form cutting edges. A hollow section (26) is formed in the center. As shown in Figure 4, the ear pick-shaped tip (23) of the spiral member (2) can be inserted into the annular gap (14) formed between the inner wall (11) of the heated tobacco body (10) and the broken stick piece (17) by rotating it. As the rotation continues, as shown in Figure 5, the ridge portion (25) engages with the broken stick piece (17) at multiple points, and the spiral member (2) wraps around the entire circumference. At this time, the paper-wrapped member is held by geometric constraints, making it less likely to loosen and allowing it to be pulled out in a straight line. This invention features a structure in which the encasing process progresses depending on the spiral winding direction, allowing for stable removal through rotational operation in a consistent direction. [Examples]
[0008] As one embodiment of this invention, the spiral member is formed from a strip of stainless steel metal, and the structure is configured to have rigidity comparable to that of a wine opener. When a broken tobacco stick remains inside the insertion port of a heated tobacco device, the cleaning tool of this invention is inserted and rotated in a certain direction, causing the ear pick-like tip to slip into the annular gap and, as it rotates, to enclose the tobacco stick all the way around. After that, by linearly pulling out the cleaning tool, the damaged paper-wound member could be removed without excessively damaging the inner wall of the main body.
Industrial Applicability
[0009] The cleaning tool of the present invention can be used for the purpose of removing the paper-wound member of the tobacco stick remaining inside the insertion port of the heated tobacco. The present invention can be mass-produced as a cleaning product and can be widely used as a maintenance and management product for the heated tobacco main body.
