Description

Technical Field

[0001] This utility model relates to the field of cigarette technology, and in particular to a heated cigarette filter and a heated cigarette. Background Technology

[0002] With increasing public awareness of health, the relationship between smoking and health has attracted significant attention. As an alternative to traditional cigarettes, the aerosol properties of heated cigarettes and their impact on the human respiratory system have become a focus of research. In the human respiratory system, the cilia in the bronchi play a crucial cleaning role, removing inhaled foreign objects and aerosol particles, thus maintaining respiratory health. However, current conventional heated cigarette filters are insufficient in regulating the aerosol surface potential characteristics, failing to assist the cilia in clearing aerosols and thus failing to adequately meet the need to reduce the harm of smoking. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a heated cigarette filter and a heated cigarette, which solves the problem that the heated cigarette filter is insufficient in regulating the surface potential characteristics of aerosols in the prior art, and cannot assist the cilia in the bronchi of the human respiratory system in clearing aerosols.

[0004] This utility model solves the above-mentioned technical problems through the following technical means: A heated cigarette filter includes a piezoelectric material fiber segment comprising polyvinylidene fluoride (PVDF) fiber and acetate fiber, wherein the PVDF fiber is distributed within the acetate fiber, and the PVDF fiber is used to change the surface potential of aerosol particles.

[0005] By setting the above structure, when the airflow passes through the filter, the impact force of the airflow causes the piezoelectric material fiber segment to deform and generate charges. The charges interact with the passing aerosol particles, changing the surface potential of the aerosol particles, effectively assisting the cilia in clearing aerosols, improving the aerosol clearance efficiency, and reducing lung deposits.

[0006] Furthermore, it also includes aerosol cluster segments connected to piezoelectric material fiber segments, the aerosol cluster segments being used to cause aerosol particles to collide and aggregate with each other.

[0007] By setting up the above structure, when the airflow passes through the aerosol cluster section, it causes the aerosol particles to collide and aggregate with each other. The aggregated aerosol particles are relatively more stable, reducing particle dispersion caused by factors such as Brownian motion, which helps the particles grow and makes it easier to form a perceptible aerosol particle size at the suction end.

[0008] Furthermore, the aerosol cluster segment includes a tube body and a structural component disposed within the tube body, the structural component being used to change the airflow direction within the tube body.

[0009] By setting up the above structure, the incoming air and the aerosol generated by heating the cigarette form a specific flow field in the tube, which promotes the collision and aggregation of aerosol particles.

[0010] Furthermore, the structural component includes a column that divides the interior of the tube into two cavities. The column has several through holes, and the two cavities are connected through the several through holes.

[0011] Furthermore, the structural component includes a helical component, which forms a helical channel within the tube.

[0012] Furthermore, each end of the spiral component is provided with a mounting block, which is in close contact with the inner wall of the tube, and the mounting block is provided with multiple slots.

[0013] A heated cigarette includes a heated cigarette filter and a tobacco segment, wherein the heated cigarette filter is any of the heated cigarette filters described above, the tobacco segment is connected to an aerosol cluster segment of the heated cigarette filter, and a splicing paper is wrapped at the joint between the heated cigarette filter and the tobacco segment.

[0014] Furthermore, the aerosol cluster section is provided with a plurality of first air inlets, and the tipping paper is provided with a plurality of second air inlets. The second air inlets are connected to the first air inlets to ensure that external air from the cigarette enters the aerosol cluster section through the air inlets.

[0015] The beneficial effects of this utility model are: By incorporating piezoelectric fiber segments and aerosol cluster segments, the aerosol cluster segments first promote collisions and aggregation of aerosol particles, resulting in more stable aerosol particles and reducing particle dispersion caused by factors such as Brownian motion. Subsequently, as the aerosol passes through the piezoelectric fiber segments, the impact force of the airflow causes the piezoelectric fibers to deform and generate charges. These charges interact with the passing aerosol particles, altering their surface potential and effectively assisting cilia in removing aerosols, thereby improving aerosol removal efficiency and reducing aerosol deposition in the respiratory system.

Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0019] Example 1: As Figure 2 As shown, a heated cigarette filter of this embodiment includes a piezoelectric material fiber segment 1 and an aerosol cluster segment 2 connected together. The piezoelectric material fiber segment 1 is located at the end away from the tobacco segment 3, and the aerosol cluster segment 2 is located at the end close to the tobacco segment 3. The piezoelectric material fiber segment 1 is used to change the surface potential of the aerosol particles, and the aerosol cluster segment 2 is used to cause the aerosol particles to collide and agglomerate with each other.

[0020] First, the aerosol agglomeration segment 2 promotes collisions and aggregation of aerosol particles. Agglomerated aerosol particles are relatively more stable, reducing particle dispersion caused by factors such as Brownian motion. Then, when the airflow passes through the piezoelectric material fiber segment 1, the impact force of the airflow causes the piezoelectric material fibers in segment 1 to deform and generate charges. These charges interact with the passing aerosol particles, changing the surface potential of the aerosol particles and effectively assisting the cilia in removing aerosols, improving the aerosol removal efficiency and reducing aerosol deposition in the respiratory system.

[0021] For example, for negatively charged aerosol particles, piezoelectric fiber generates a positive charge, which attracts the particles to approach, changes the charge distribution on the particle surface, and thus adjusts its surface potential.

[0022] In this embodiment, the piezoelectric material fiber segment 1 includes polyvinylidene fluoride (PVDF) fiber and acetate fiber. Specifically, the PVDF fiber is distributed within the acetate fiber. In other embodiments, composite fibers with good flexibility and electrochemical properties can also be produced by spinning ZnO nanowires mixed with piezoelectric polymers such as PVDF. In this embodiment, the PVDF fiber is an electrospun PVDF nanofiber, which not only possesses certain piezoelectric properties and can generate charge under airflow impact to assist in controlling the aerosol potential, but its unique nanofiber structure can also increase the contact area with aerosol particles and enhance the charge interaction effect.

[0023] In this embodiment, the aerosol cluster segment 2 includes a tube body 21 and a structural member 22 disposed within the tube body 21. The structural member 22 is used to change the airflow direction within the tube body 21. The incoming air and the aerosol generated by heating the cigarette form a specific vortex flow field within the tube body 21, causing the aerosol particles to collide and agglomerate.

[0024] In this embodiment, the structural component 22 includes a column 4, which divides the interior of the tube 21 into two cavities 41. The column 4 has several through holes 42, and the two cavities 41 are connected through the several through holes 42. After the aerosol enters the cavity 41 on the left side of the column 4, the airflow is blocked by the column 4 to form a vortex. It first collides and agglomerates in the cavity 41 close to the tobacco segment 3. Then, the aerosol enters the cavity 41 of the column 4 away from the tobacco segment 3 through the through holes 42, forming a Venturi effect. In the environmental change of increased airflow pressure and decreased flow velocity, the collision frequency between aerosol particles increases, and they collide and agglomerate again, forming the aerosol physical state that consumers can perceive.

[0025] Example 2: Figure 3 As shown, this embodiment provides a heated cigarette filter. The structure of the heated cigarette filter in this embodiment is the same as that in Embodiment 1, except that: In this embodiment, the structural component 22 includes a spiral component 5, which forms a spiral channel 51 within the tube body 21. The spiral channel 51 serves as an airflow channel, through which aerosols flow. Within the complex flow field formed by centrifugal force, airflow shear force, and prolonged flow time, airflow disturbances significantly promote aerosol collision and aggregation.

[0026] In this embodiment, mounting blocks 52 are provided at both ends of the spiral component 5. The mounting blocks 52 are in close contact with the inner wall of the tube body 21, which can fix the spiral component 5 and prevent the spiral component 5 from shifting. Multiple slots 521 are provided on the mounting blocks 52. The slots 521 serve as airflow channels, and airflow can flow into or out of the spiral channel 51 of the spiral component 5 through the slots 521.

[0027] Example 3: Figure 1-3 As shown, this embodiment provides a heated cigarette, including a heated cigarette filter and a tobacco segment 3. The heated cigarette filter is the heated cigarette filter of Embodiment 1 or Embodiment 2. The tobacco segment 3 is connected to the aerosol cluster segment 2 of the heated cigarette filter. A splicing paper 31 is wrapped at the joint between the heated cigarette filter and the tobacco segment 3.

[0028] The aerosol cluster section 2 has several first air inlets 211. In this embodiment, the first air inlets 211 are located on the tube body 21, and the connector paper 31 has several second air inlets 311 connected to the first air inlets 211. During suction, outside air can enter the filter tip through the second air inlets 311 and the first air inlets 211.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
