Description

Technical Field

[0001] This utility model relates to the technology of heated non-combustible smoking devices, and in particular to a cleaning-free filter tip for heated non-combustible smoking devices. Background Technology

[0002] Heated tobacco products, due to their low tar and low harm characteristics, are gradually becoming a substitute for traditional cigarettes. However, their filter design still has obvious technical defects, which restricts the user experience.

[0003] Existing heated tobacco products typically have an interconnected heating chamber and a filter chamber. The cigarette is inserted into the heating chamber, and the filter is inserted into the filter chamber. The heating chamber heats the cigarette, and the resulting smoke is inhaled by the user through the filter. However, in traditional heated tobacco products, the cigarette and filter are usually positioned end-to-end. During inhalation, smoke can enter the heating chamber or filter chamber through the gap between the cigarette and the filter. Since the smoke contains substances such as tar, over time, tar and dirt will form on the inner walls of the heating chamber and filter chamber. This dirt will affect the insertion of the cigarette or filter, as well as the heating performance of the heating chamber, and is difficult to clean.

[0004] Therefore, there is an urgent need to design a cleaning-free heated non-combustible smoke filter to address the shortcomings of existing technologies. Utility Model Content

[0005] In response to the problems of existing heated tobacco filter tips, such as scale buildup on the inner wall of the cavity due to the "cigarette-filter gap", which makes cleaning difficult and reduces performance, this utility model provides a clean-free heated tobacco filter tip. It aims to eliminate the smoke leakage channel, avoid the accumulation of tar and dirt, achieve the core function of "no cleaning required", and improve the filter tip's versatility and smoking experience.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: a cleaning-free filter for a heated non-combustible tobacco device, used in conjunction with the heated non-combustible tobacco device, wherein the heated non-combustible tobacco device includes a filter cavity and a heating cavity that are interconnected, the cleaning-free filter includes a filter body, the filter body is configured as a tubular structure and includes a mouthpiece section and a cigarette insertion section, the cigarette insertion section is detachably inserted into the filter cavity, and the inner diameter of the cigarette insertion section matches the inner diameter of the heating cavity and is used for inserting a cigarette filter.

[0007] A preferred technical solution is that the inner diameter of the filter cavity is matched with the outer diameter of the cigarette insertion section.

[0008] The preferred technical solution is that the inside of the cigarette insertion section has stepped holes, and the stepped holes have multiple inner diameters corresponding to cigarettes of different outer diameters.

[0009] A preferred technical solution is as follows: a partition is provided between the mouthpiece section and the cigarette insertion section, and the partition is provided with a plurality of ventilation holes in the circumferential direction that connect the mouthpiece section and the cigarette insertion section.

[0010] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0011] This utility model provides a cleaning-free filter for a heated non-combustible smoking device. Through a design where the outer diameter of the cigarette insertion section matches the filter cavity and the inner diameter of the insertion section matches the heating cavity for cigarette filter insertion, it completely eliminates the end-to-end seam between the cigarette and filter in traditional structures. Smoke cannot leak into the heating cavity or the inner wall of the filter cavity, preventing the accumulation of tar and dirt from the source and eliminating the need for any cleaning of the device's cavity. The detachable design enhances convenience: the detachable structure of the cigarette insertion section allows users to directly replace the entire filter (without cleaning the old filter). Typically, a new filter is needed after 10-15 uses, simplifying the usage process and reducing maintenance costs. Attached Figure Description
