Technical solutions of embodiments of the present disclosure will be described clearly and completely below with reference to accompanying drawings in embodiments of the present disclosure. Apparently, embodiments described herein are merely some embodiments, rather than all embodiments, of the present disclosure. Based on embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort shall fall within the protection scope of the present disclosure.

The phrase appearing in various places in the specification does not necessarily refer to the same embodiment, nor does it refer an independent or alternative embodiment that is mutually exclusive with other embodiments. It is expressly and implicitly understood by those skilled in the art that an embodiment described herein may be combined with other embodiments.

It may be noted that terms “first”, “second”, and the like used in the specification, the claims, and the accompany drawings of the present disclosure are used to distinguish different objects rather than describe a particular order. In addition, the terms “comprise”, “include”, and “have” as well as variations thereof are intended to cover non-exclusive inclusion.

A cooling assembly 10 is provided in the present disclosure. In implementations of the present disclosure, the cooling assembly 10 can be applied to a heat-not-burn cartridge 1. The smoke generating member 30 in the heat-not-burn cartridge 1 produces high-temperature aerosol when being heated. The cooling assembly 10 is configured to cool the aerosol. For example, a temperature of the aerosol produced when the smoke generating member 30 is heated is usually a first temperature (e.g., 200° C. to 380° C.). After the aerosol of the first temperature passes through the cooling assembly 10, the temperature of the aerosol becomes a second temperature. The second temperature is lower than the first temperature. The aerosol of the second temperature is more suitable for a user to draw. The application of the cooling assembly 10 to the heat-not-burn cartridge 1 is described as an application scenario of the cooling assembly 10, and may not be understood as a limitation to the cooling assembly 10 provided in the implementations of the present disclosure. The structure of the cooling assembly 10 is described in detail below. Reference can be made to FIG. 1, FIG. 2, and FIG. 3 together, where FIG. 1 is a schematic perspective view of a cooling assembly provided in an implementation of the present disclosure, FIG. 2 is an exploded perspective view of the cooling assembly illustrated in FIG. 1, and FIG. 3 is a cross-sectional view of the cooling assembly illustrated in FIG. 1 taken along line I-I. The cooling assembly 10 includes a cooling member 110, a first closing member 120, and a second closing member 130. The cooling member 110 has a first end 111 and a second end 112 opposite to the first end 111, and defines a cooling passage 110a penetrating through the first end 111 and the second end 112. The first closing member 120 is fixed to the first end 111. The first closing member 120 defines at least one first through-hole 121. The at least one first through-hole 121 is in communication with the cooling passage 110a. The second closing member 130 is fixed to the second end 112. The second closing member 130 defines at least one second through-hole 131. The at least one second through-hole 131 is in communication with the cooling passage 110a.

The cooling member 110 is in a shape of a round tube or a round-like tube. The cooling member 110 may also be in the shape of a rectangular tube, an elliptical tube, an elliptical-like tube, or a polygonal tube, which is not limited in implementations of the present disclosure. The cooling passage 110a allows aerosol to pass through. When the aerosol flows in the cooling passage 110a, the temperature of the aerosol is gradually reduced.

In an implementation, a material of the cooling member 110 includes a food-grade material. When aerosol flows through the cooling passage 110a of the cooling member 110, the cooling member 110 produces less or even no toxic substance when being heated. For example, the material of the cooling member 110 may include, but is not limited to, white cardboard paper or kraft paper.

Optionally, when the cooling member 110 is made of white cardboard paper, the white cardboard paper is white cardboard paper of 50 g/m²-200 g/m², so that the cooling member 110 has a good cooling performance and a good strength, and is not easily deformed. When the cooling member 110 is made of kraft paper, the cooling member 110 is kraft paper of 50 g/m²-200 g/m², so that the cooling member 110 has a good cooling performance and a good strength, and is not easily deformed.

It can be understood that in an implementation, the material of the cooling member 110 may also include PLA, silicone, or an injection-molded part, as long as the cooling member 110 is capable of lowering the temperature.

The manner in which the first closing member 120 is fixed to the first end 111 may be, but is not limited to, adhesion by a glue or fixing by an adhesive tape. In this implementation, the first closing member 120 is fixed to the first end 111 by means of a glue. In an implementation, the glue is a food-grade glue. When aerosol passes through the cooling member 110, the glue produces less or even no toxic substance when being heated. The food-grade glue may be, but is not limited to, a glutinous rice glue, a lap glue, a straw glue, a white emulsion glue, etc.

In this implementation, for example, the first closing member 120 is fixed to an end surface of the first end 111 away from the second end 112. It can be understood that in another implementation, the first closing member 120 may also be fixed to a peripheral side surface of the first end 111. Alternatively, in yet another implementation, the first closing member 120 may be fixed to the end surface of the first end 111 away from the second end 112, and is fixed to the peripheral side surface of the first end 111.

In an implementation, a material of the first closing member 120 may include, but is not limited to, silk tissue paper, air-permeable paper, or butter paper. The silk tissue paper, the air-permeable paper, and the butter paper all have good air permeability, which is beneficial for the aerosol to pass through. When the first closing member 120 is made of silk tissue paper, the first closing member 120 is made of silk tissue paper of 1 g/m²-50 g/m². When the first closing member 120 is made of air-permeable paper, the first closing member 120 is made of air-permeable paper of 1 g/m²-50 g/m². When the first closing member 120 is made of butter paper, the first closing member 120 is made of butter paper of 45 g/m²-105 g/m².

In addition, in order to reduce resistance to draw when the aerosol is drawn, the first closing member 120 defines at least one first through-hole 121 in communication with the cooling passage 110a.

The manner in which the second closing member 130 is fixed to the second end 112 may be, but is not limited to, adhesion by a glue or fixing by an adhesive tape. In this implementation, the second closing member 130 is fixed to the second end 112 by means of a glue. In an implementation, the glue is a food-grade glue. When the aerosol passes through the cooling member 110, the glue produces less or even no toxic substance when being heated. The food-grade glue may be, but is not limited to, a glutinous rice glue, a lap glue, a straw glue, a white emulsion glue, etc. It may be understood that the manner in which the second closing member 130 is fixed to the second end 112 is the same as or different from the manner in which the first closing member 120 is fixed to the first end 111, which is not limited in implementations of the present disclosure.

In this implementation, for example, the second closing member 130 is fixed to an end surface of the second end 112 away from the first end 111. It can be understood that in another implementation, the second closing member 130 may also be fixed to a peripheral side surface of the second end 112. Alternatively, in yet another implementation, the second closing member 130 is fixed to the end surface of the second end 112 away from the first end 111, and is fixed to the peripheral side surface of the second end 112.

In an implementation, a material of the second closing member 130 may include, but is not limited to, silk tissue paper, air-permeable paper, or butter paper. The silk tissue paper, the air-permeable paper, and the butter paper all have good air permeability, which is beneficial for the aerosol to pass through. When the second closing member 130 is made of silk tissue paper, the second closing member 130 is made of silk tissue paper of 1 g/m²-50 g/m². When the second closing member 130 is made of air-permeable paper, the second closing member 130 is made of air-permeable paper of 1 g/m²-50 g/m². When the second closing member 130 is made of butter paper, the second closing member 130 is made of butter paper of 45 g/m²-105 g/m². The second closing member 130 and the first closing member 120 may be made of the same material or different materials, which is not limited in implementations of the present disclosure.

In addition, in order to reduce resistance to draw when the aerosol is drawn, the second closing member 130 defines at least one second through-hole 131 in communication with the cooling passage 110a.

In summary, in the cooling assembly 10 provided in implementations of the present disclosure, the first closing member 120 is fixed to the first end 111 of the cooling member 110, the second closing member 130 is fixed to the second end 112 of the cooling member 110. Therefore, when the cooling assembly 10 is assembled into the heat-not-burn cartridge 1, the first end 111 and the second end 112 of the cooling assembly 10 do not need to be distinguished, so that the complexity in assembling the cooling assembly 10 can be reduced, and thus the assembly efficiency is improved.

In addition, the first closing member 120 is fixed to the first end 111, and the second closing member 130 is fixed to the second end 112, so that the cooling member 110 has good support effects at both the first end 111 and the second end 112, thereby preventing the cooling member 110 from being deformed. Moreover, when the cooling assembly 10 is assembled into the heat-not-burn cartridge 1, less or even no filter member 40 enters the cooling member 110.

Reference can be made to FIG. 4 and FIG. 5A to 5D, where FIG. 4 is a schematic structural view of a first closing member in FIG. 1, and FIG. 5A to FIG. 5D are respectively schematic structural views of first closing members according to another implementation. The at least one first through-hole 121 is implemented as six to thirteen first through-holes. A diameter of each first through-hole 121 ranges from 0.6 mm to 1.0 mm. A distance between any two adjacent first through-holes 121 of the six to thirteen first through-holes ranges from 0.8 to 1.0 mm.

The first closing member 120 may be formed by die stamping, cutter punching, or laser cutting. The first through-hole 121 may be defined by die stamping, cutter punching, or laser cutting. A manufacturing process of the first closing member 120 may be the same as or different from a manufacturing process of the first through-hole 121.

The first through-hole 121 may be circular, elliptical, polygonal, trapezoidal, trapezoidal-like, or the like, which is not limited herein.

When the first through-hole 121 is circular, the diameter of the first through-hole 121 is the diameter of the circle. When the first through-hole 121 is non-circular, the diameter of the first through-hole 121 refers to a distance between two points of the first through-hole 121 with the largest dimension. When the first through-hole 121 is non-circular, the distance between two points of the first through-hole 121 with the largest dimension is the equivalent diameter of the first through-hole 121.

With the above structural design of the at least one first through-hole 121 in the first closing member 120 provided in implementations of the present disclosure, on the one hand, the aerosol can uniformly pass through, and the resistance to draw when the aerosol is drawn can be reduced; and on the other hand, the structural strength of the first closing member 120 can also be maintained, so that the first closing member 120 is not easily broken.

Reference can be made to FIG. 6 and FIG. 7A to FIG. 7D, where FIG. 6 is a schematic structural view of a second closing member in FIG. 1, and FIG. 7A to FIG. 7D are respectively schematic structural views of second closing members according to another implementation. The at least one second through-hole 131 is implemented as six to thirteen second through-holes 131. A diameter of each second through-hole 131 ranges from 0.6 mm to 1.0 mm. A distance between any two adjacent second through-holes 131 of the six to thirteen second through-holes 131 ranges from 0.8 mm to 1.0 mm.

The second closing member 130 may be formed by die stamping, cutter punching, or laser cutting. The second through-hole 131 may be defined by die stamping, cutter punching, or laser cutting. A manufacturing process of the second closing member 130 may be the same as or different from a manufacturing process of the second through-hole 131.

The second through-hole 131 may be circular, elliptical, polygonal, trapezoidal, trapezoidal-like, or the like, which is not limited herein.

When the second through-hole 131 is circular, the diameter of the second through-hole 131 is the diameter of the circle. When the second through-hole 131 is non-circular, the diameter of the second through-hole 131 refers to a distance between two points of the second through-hole 131 with the largest dimension. When the second through-hole 131 is non-circular, the distance between two points of the second through-hole 131 with the largest dimension is the equivalent diameter of the second through-hole 131.

With the above structure design of the at least one second through-hole 131 in the second closing member 130 provided in implementations of the present disclosure, on the one hand, the aerosol can uniformly pass through, and the resistance to draw when the aerosol is drawn can be reduced; and on the other hand, the structural strength of the second closing member 130 can also be maintained, so that the second closing member 130 is not easily broken.

It can be understood that in an implementation, the second through-hole 131 faces the first through-hole 121. In other implementations, the second through-hole 131 and the first through-hole 121 are partially staggered or completely staggered, which is not limited herein.

It may be understood that the number of the second through-holes 131 may be the same as or different from the number of the first through-holes 121. The shape of the second through-hole 131 may be the same as or different from the shape of the first through-hole 121. The arrangement rule of the second through-holes 131 may be the same as or different from the arrangement rule of the first through-holes 121. The diameter of the second through-hole 131 may be the same as or different from the diameter of the first through-hole 121.

Reference can be made to FIG. 8, which is a schematic view of a distance between a first through-hole at an outermost peripheral side of first through-holes in a first closing member in FIG. 1 and an outer peripheral edge of the first closing member in FIG. 1. A distance between a first through-hole 121 at an outermost peripheral side of first through-holes 121 in the first closing member 120 and an outer peripheral edge of the first closing member 120 ranges from 0.7 mm to 0.8 mm. In FIG. 8, the distance between the first through-hole 121 at the outermost peripheral side of first through-holes 121 in the first closing member 120 and the outer peripheral edge of the first closing member 120 is marked as d1, which satisfies 0.7 mm≤d1≤0.8 mm. In FIG. 8, L1 is a tangent of the first through-hole 121 at point A, and L2 is a tangent of the first closing member 120 at point B, where connection line AB passes through the center of the first closing member 120.

When the first closing member 120 is fixed to the cooling member 110, a certain adhesive width, such as, 0.3 mm to 0.4 mm, needs to be set aside. In addition, when the first through-hole 121 is machined, a machining tolerance may exist. In order to prevent the first through-hole 121 from being machined to the edge of the first closing member 120 or prevent the first through-hole 121 from being machined to the position where the first closing member 120 is adhered to the glue, a distance of about 0.4 mm may be set aside. It can be seen therefrom that by setting the distance between the first through-hole 121 located at the outermost peripheral side of first through-holes 121 and the outer peripheral edge of the first closing member 120 to range from 0.7 mm to 0.8 mm, on the one hand, the requirement that the first closing member 120 is adhered to the cooling member 110 can be met, and on the other hand, the requirement of the machining tolerance during machining of the first through-hole 121 can be met.

Reference can be made to FIG. 9, which is a schematic view of a distance between a second through-hole at an outermost peripheral side of second through-holes in a second closing member in FIG. 1 and an outer peripheral edge of the second closing member in FIG. 1. A distance between a second through-hole 131 located at an outermost peripheral side of second through-holes 131 in the second closing member 130 and an outer peripheral edge of the second closing member 130 ranges from 0.7 mm to 0.8 mm. In FIG. 9, the distance between the second through-hole 131 located at the outermost peripheral side of second through-holes 131 in the second closing member 130 and the outer peripheral edge of the second closing member 130 is marked as d2, which satisfies 0.7 mm≤d2≤0.8 mm. In FIG. 9, L3 is a tangent of the second through-hole 131 at point C, and L4 is a tangent of the second closing member 130 at point D, where connection line CD passes through the center of the second closing member 130.

When the second closing member 130 is fixed to the cooling member 110, a certain adhesive width, such as, 0.3 mm to 0.4 mm, needs to be set aside. In addition, when the second through-hole 131 is machined, a machining tolerance may exist. In order to prevent the second through-hole 131 from being machined to the edge of the second closing member 130 or prevent the second through-hole 131 from being machined to the position where the second closing member 130 is adhered to the glue, a distance of about 0.4 mm may be set aside. It can be seen therefrom that by setting the distance between the second through-hole 131 located at the outermost peripheral side of second through-holes 131 and the outer peripheral edge of the second closing member 130 to range from 0.7 mm to 0.8 mm, on the one hand, the requirement that the second closing member 130 is adhered to the cooling member 110 can be met, and on the other hand, the requirement of the machining tolerance during machining of the second through-hole 131 can be met.

Reference can be made to FIG. 10, which is a schematic structural view of a cooling member provided in an implementation. In this implementation, the cooling member 110 includes multiple convolute-wound cooling layers 1111. When the cooling member 110 includes multiple convolute-wound cooling layers 1111, the number of the cooling layers 1111 may be 3 to 6, such as, 3, 4, 5, or 6. The cooling member 110 includes multiple convolute-wound cooling layers 1111, so that the cooling member 110 has good strength and is not easily deformed.

It may be noted that in the so-called convolute wound means that, seam L01 of the cooling layer 1111 is parallel or substantially parallel to centerline L02 of the cooling member 110.

FIG. 11 is a schematic structural view of a cooling member provided in another implementation. In this implementation, the cooling member 110 includes multiple spiral-wound cooling layers 1111.

In this implementation, the cooling member 110 includes multiple spiral-wound cooling layers 1111. When the cooling member 110 includes multiple spiral-wound cooling layers 1111, the number of the cooling layers 1111 may be 2 to 4, such as, 2, 3, or 4. The cooling member 110 includes multiple spiral-wound cooling layers 1111, so that the cooling member 110 has good strength and is not easily deformed.

It may be noted that the so-called spiral wound means that, extension line L01 at a seam between adjacent cooling layers 1111 is inclined relative to centerline L02 of the cooling member 110, for example, an angle of inclination of 135°±15° exists between extension line L01 and centerline L02. The angle of inclination of 135°±15° may also be regarded as 45°±15°. In other words, an angle between extension line L01 and centerline L2 is 45°±15°.

Compared with the cooling member 110 including multiple convolute-wound cooling layers 1111, for the cooling member 110 including multiple spiral-wound cooling layers 1111, the multiple spiral-wound cooling layers 1111 are fixed to each other by means of adhesive glue. Therefore, the multiple cooling layers 1111 can be firmly fixed to each other, so that the cooling member 110 has better stability, better strength, and better roundness (which means that an opening of the cooling member 110 is more rounded).

Reference can be made to FIG. 12, which is a schematic view of dimensions of an outer diameter and an inner diameter of a cooling member in FIG. 1. The cooling member 110 is tubular, and an outer diameter (marked as D1 in FIG. 12) of the cooling member 110 may range from 6.0 mm to 6.6 mm. An inner diameter (marked as D2 in FIG. 12) of the cooling member 110 may range from 6.2 mm to 6.4 mm.

The inner diameter of the cooling member 110 is smaller than the outer diameter of the cooling member 110. A range of the inner diameter of the cooling member 110 is slightly different from a range of the outer diameter of the cooling member 110. Therefore, for a cooling member 110 with a fixed outer diameter, the cooling member 110 has a relatively large inner diameter, that is, the cooling passage 110a has a relatively large radial dimension, so that the cooling member 110 has a good cooling effect on aerosol. In addition, a large amount of aerosol can also be stored in the cooling passage 110a. When the heat-not-burn cartridge 1 applying the cooling assembly 10 is drawn, the amount of aerosol during draw may also be uniform.

The diameter of the first closing member 120 is adaptive to the outer diameter of the cooling member 110, for example, the diameter of the first closing member 120 ranges from 6.0 mm to 6.6 mm.

The diameter of the second closing member 130 is adaptive to the outer diameter of the cooling member 110, for example, the diameter of the second closing member 130 ranges from 6.0 mm to 6.6 mm.

Reference can be made to FIG. 13, FIG. 14, FIG. 15, and FIG. 16 together, where FIG. 13 is a schematic perspective structural view of a heat-not-burn cartridge provided in an implementation of the present disclosure, FIG. 14 is an exploded perspective view of the heat-not-burn cartridge in FIG. 13, FIG. 15 is a cross-sectional view in FIG. 13 taken along line II-II, and FIG. 16 is an enlarged schematic view at circle III in FIG. 15. The heat-not-burn cartridge 1 includes a first tube 20, a smoke generating member 30, a cooling assembly 10, and a filter member 40. The first tube 20 defines an accommodating space 210. The smoke generating member 30 is disposed in the accommodating space 210 and located at one end of the first tube 20. The cooling member 110 is disposed in the accommodating space 210, and the cooling assembly 10 is disposed at one side of the smoke generating member 30. The specific structure of the cooling member 110 is described above and will not be repeated herein. The filter member 40 is disposed in the accommodating space 210, and is disposed at one side of the cooling member 110 away from the smoke generating member 30.

The first tube 20 is in a shape of a round tube or a round-like tube. The first tube 20 may also be in the shape of a rectangular tube, an elliptical tube, an elliptical-like tube, or a polygonal tube, which is not limited in implementations of the present disclosure.

In an implementation, one end of the first tube 20 is closed to prevent exposure of the smoke generating member 30 from the first tube 20. Specifically, in an implementation, the heat-not-burn cartridge 1 further include a sealing member 60. The sealing member 60 is disposed at one end of the first tube 20 to seal the first tube 20. The sealing member 60 is disposed at one side of the smoke generating member 30 away from the cooling assembly 10. A material of the scaling member 60 may include, but is not limited to, silk tissue paper, air-permeable paper, or butter paper. For example, the material of the sealing member 60 may include silk tissue paper of 1 g/m²-50 g/m², air-permeable paper of 1 g/m²-50 g/m², or butter paper of 45 g/m²-105 g/m².

The smoke generating member 30 is also referred to as a smoke generating section. The smoke generating member 30 includes an aerosol-generating substrate (such as multiple smoke generating particles, multiple smoke generating sheets, or multiple smoke generating particles and multiple smoke generating sheets). A material of the aerosol-generating substrate includes tobacco or a non-tobacco plant herbaceous unit. When the aerosol-generating substrate includes the non-tobacco plant herbaceous unit, the aerosol-generating substrate does not produce harmful substances such as tar, nicotine, or the like. In addition, when the plant herbaceous unit is heated, the plant herbaceous unit will not burn, pollute the surrounding environment, or affect the surrounding people, thereby ensuring the physical health of people who draw the heat-not-burn cartridge 1 and the physical health of the surrounding people. Moreover, when the plant herbaceous unit in the aerosol-generating substrate includes a material of a traditional Chinese medicine (such as ginseng and Gastrodia elata), the heat-not-burn cartridge 1 can have a good health care function.

When the smoke generating member 30 includes smoke generating particles or smoke generating sheets, the smoke generating member 30 is less likely to remain in the smoking set during heating of the heat-not-burn cartridge 1 by the smoking set, thereby ensuring the cleanliness of the smoking set. In addition, when the smoke generating member 30 includes the smoke generating particles or the smoke generating sheets, gaps are likely to exist between the smoke generating particles or between the smoke generating sheets, and sufficient air can be present in the gaps, so that the smoke generating member 30 produces the aerosol when being heated by the smoking set.

In this implementation, for example, the first closing member 120 of the cooling assembly 10 is disposed close to the smoke generating member 30. In another implementation, the second closing member 130 of the cooling assembly 10 is disposed close to the smoke generating member 30.

The filter member 40 is disposed in the accommodating space 210, and is disposed at one side of the cooling member 110 away from the smoke generating member 30. The filter member 40 may abut against the cooling assembly 10, or may be spaced apart from the cooling assembly 10, which is not limited in the present disclosure.

A material of the filter member 40 may include, but is not limited to, PLA fibers. The filter member 40 can filter the aerosol, thereby improving the taste of the heat-not-burn cartridge 1. In an implementation, the filter member 40 is disposed in a compressed state in the first tube 20, to prevent the filter member 40 from falling out of the first tube 20.

When being heated, the smoke generating member 30 produces aerosol of a high temperature. Specifically, when being heated, the smoke generating member 30 may produce aerosol of a first temperature (e.g., 200° C. to 380° C.). The heat-not-burn cartridge 1 is drawn through the filter member 40, so that the aerosol of the first temperature passes through the cooling assembly 10 and the filter member 40 in sequence. After the aerosol of the first temperature flows through the cooling assembly 10, the temperature of the aerosol is reduced to a second temperature. The second temperature is lower than the first temperature. The aerosol of the second temperature is more suitable for the user to draw, thereby preventing the user from being scalded.

Referring to FIG. 15 again, the length of the smoke generating member 30 ranges from 13 mm to 18 mm. The length of the cooling assembly 10 ranges from 16 mm to 23 mm. The length of the filter member 40 ranges from 8 mm to 10 mm.

With the above dimensions of the smoke generating member 30, the cooling assembly 10, and the filter member 40 in the heat-not-burn cartridge 1 provided in implementations of the present disclosure, on the one hand, the smoke generating member 30 can produce more aerosol, and on the other hand, the cooling assembly 10 can have a good cooling effect on the aerosol produced by the smoke generating member 30. In addition, the filter member 40 has a good filtering effect on the aerosol, so that the heat-not-burn cartridge 1 provides a good draw experience.

Reference can be made to FIG. 17, FIG. 18, FIG. 19, and FIG. 20 together, where FIG. 17 is a schematic perspective structural view of a heat-not-burn cartridge provided in another implementation of the present disclosure, FIG. 18 is an exploded perspective view of the heat-not-burn cartridge in FIG. 17, FIG. 19 is a cross-sectional view in FIG. 17 taken along line IV-IV, and FIG. 20 is an enlarged schematic view at circle V in FIG. 19. In this implementation, the heat-not-burn cartridge 1 further includes a second tube 150 sleeved on a peripheral side surface of the first tube 20.

Specifically, when the heat-not-burn cartridge 1 is manufactured, due to various reasons, defects may exist on the appearance of the first tube 20. For example, the smoke generating member 30 may cause the first tube 20 to be stained, or cause the first tube 20 to be scratched.

The second tube 150 is sleeved on the peripheral side surface of the first tube 20 and can shield the first tube 20, so that the heat-not-burn cartridge 1 is more beautiful. In an implementation, a material of the second tube 150 includes tipping paper. In an implementation, the tipping paper is tipping paper of 32 g/m²-40 g/m². In an implementation, the heat-not-burn cartridge 1 satisfies at least one of the following. A material of the first tube 20 includes white cardboard paper of 50 g/m²-200 g/m² or kraft paper of 50 g/m²-200 g/m². The first tube 20 has a length ranging from 42 mm to 46 mm, and when the heat-not-burn cartridge 1 further includes a second tube 150, the second tube 150 has a length ranging from 42 mm to 46 mm. The cooling member 110 has an outer diameter ranging from 6.0 mm to 6.6 mm, the first tube 20 has an inner diameter ranging from 6.4 mm to 6.65 mm, the first tube 20 has an outer diameter ranging from 6.9 mm to 7.1 mm, the filter member 40 has an outer diameter ranging from 6.5 mm to 7.0 mm, and the filter member 40 is disposed in a compressed state in the first tube 20. When the heat-not-burn cartridge 1 further includes the second tube 150, the outer diameter of the cooling member 110 ranges from 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 ranges from 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 ranges from 6.9 mm to 7.1 mm, the outer diameter of the filter member 40 ranges from 6.5 mm to 7.0 mm, the filter member 40 is disposed in the compressed state in the first tube 20, and the second tube 150 has an outer diameter ranging from 7.15 mm to 7.3 mm.

Reference can be made to FIG. 21 to FIG. 25 together, where FIG. 21 is a schematic perspective view of a heat-not-burn cartridge provided in an implementation of the present disclosure, FIG. 22 is an exploded perspective view of the heat-not-burn cartridge illustrated in FIG. 21, FIG. 23 is a cross-sectional view of the heat-not-burn cartridge illustrated in FIG. 21 taken along line VI-VI, FIG. 24 is a schematic perspective view of a cooling assembly illustrated in FIG. 22, and FIG. 25 is an exploded perspective view of the cooling assembly in FIG. 24. The heat-not-burn cartridge 1 includes a first tube 20, a smoke generating member 30, a cooling assembly 10, and a filter member 40. The first tube 20 defines an accommodating space 210. The first tube 20 has a first end 20a that is closed and a second end 20b that is open. The smoke generating member 30 is disposed in the accommodating space 210 and located at the first end 20a of the first tube 20. At least one of the cooling assembly 10 or the smoke generating member 30 is movably disposed in the accommodating space 210. The cooling member 10 is disposed at one side of the smoke generating member 30 away from the first end 20a. The cooling assembly 10 includes a cooling member 110 and a closing member 140. The cooling member 110 defines a passage 110a. The closing member 140 is fixed to one end of the cooling member 110 and disposed closer to the smoke generating member 30 than the cooling member 110. The closing member 140 defines multiple through holes 141 in communication with the passage 110a. The filter member 40 is disposed in the accommodating space 210 and disposed at one end of the cooling member 110 away from the closing member 140.

The first tube 20 has the first end 20a and the second end 20b. In this implementation, the first end 20a is opposite to the second end 20b. The first end 20a is closed to prevent exposure of the smoke generating member 30 from the first end 20a. The second end 20b is open. When the heat-not-burn cartridge 1 is drawn by a user, the first end 20a is an end away from the lip, also referred to as a far-lip end; and the second end 20b is an end close to the lip, and is also referred to as a near-lip end.

In this implementation, the first end 20a may be sealed by a sealing member 60. The scaling member 60 is disposed at the first end 20a of the first tube 20 to seal the first tube 20. The sealing member 60 is disposed at one side of the smoke generating member 30 away from the cooling assembly 10. A material of the sealing member 60 may include, but is not limited to, silk tissue paper, air-permeable paper, or butter paper. For example, the material of the scaling member 60 may include silk tissue paper of 1 g/m²-50 g/m², air-permeable paper of 1 g/m²-50 g/m², or butter paper of 45 g/m²-105 g/m².

The first tube 20 is in a shape of a round tube or a round-like tube. The first tube 20 may also be in the shape of a rectangular tube, an elliptical tube, an elliptical-like tube, or a polygonal tube, which is not limited in implementations of the present disclosure.

The smoke generating member 30 is also referred to as a smoke generating section. The smoke generating member 30 includes an aerosol-generating substrate (such as at multiple smoke generating particles, multiple smoke generating sheets, or multiple smoke generating particles and multiple smoke generating sheets). A material of the aerosol-generating substrate includes tobacco or a non-tobacco plant herbaceous unit. When the aerosol-generating substrate includes a non-tobacco plant herbaceous unit, the aerosol-generating substrate does not produce harmful substances such as tar, nicotine, or the like. In addition, when the plant herbaceous unit is heated, the plant herbaceous unit will not burn, pollute the surrounding environment, or affect the surrounding people, thereby ensuring the physical health of people who suck the heat-not-burn cartridge 1 and the physical health of the surrounding people. Moreover, when the plant herbaceous unit in the aerosol-generating substrate includes a material of a traditional Chinese medicine (such as ginseng and Gastrodia elata), the heat-not-burn cartridge 1 can have a good health care function.

When the heat-not-burn cartridge 1 is in use, a heating member in a smoking set is usually inserted into the smoke generating member 30 to heat the smoke generating member 30. When the smoke generating member 30 is heated by the smoking set, the smoke generating member 30 can produce aerosol (commonly referred to as smoke fog), but the smoke generating member 30 has not yet reached a burning temperature and does not burn, which is also the reason why the cartridge is referred to as the heat-not-burn cartridge 1.

When the smoke generating member 30 includes smoke generating particles or smoke generating sheets, the smoke generating member 30 is less likely to remain in the smoking set during heating of the heat-not-burn cartridge 1 by the smoking set, thereby ensuring the cleanliness of the smoking set. In addition, when the smoke generating member 30 includes the smoke generating particles or the smoke generating sheets, gaps are likely to exist between the smoke generating particles or between the smoke generating sheets, and sufficient air can be present in the gaps, so that the smoke generating member 30 produces the aerosol when being heated by the smoking set.

The cooling member 110 is disposed in the accommodating space 210. According to the heat-not-burn cartridge 1 provided in implementations of the present disclosure, at least one of the cooling member 10 or the smoke generating member 30 is movably disposed in the accommodating space 210. When a heating needle of the smoking set is inserted into the smoke generating member 30, at least one of the smoke generating member 30 or the cooling assembly 10 moves, so that a density of part of the smoke generating member 30 inserted by the heating needle changes little or not, thereby less affecting or even not affecting the taste of drawing the heat-not-burn cartridge 1 (for example, the resistance to draw is relatively little and the amount of aerosol is relatively great). In other words, the heat-not-burn cartridge 1 provided in implementations of the present disclosure has a good draw taste.

The smoke generating member 30 in the heat-not-burn cartridge 1 produces a high-temperature aerosol when being heated. The aerosol is conveyed to the filter member 40 through the passage 110a of the cooling member 110 and is discharged through the filter member 40. The cooling assembly 10 is configured to cool the aerosol. For example, a temperature of the aerosol produced when the smoke generating member 30 is heated is usually a first temperature (e.g., 200° C. to 380° C.). When the aerosol of the first temperature passes through the cooling assembly 10, the temperature of the aerosol becomes a second temperature. The second temperature is lower than the first temperature. The aerosol of the second temperature is more suitable for the user to draw.

The cooling member 110 is in a shape of a round tube or a round-like tube. The cooling member 110 may also be in the shape of a rectangular tube, an elliptical tube, an elliptical-like tube, or a polygonal tube, which is not limited in implementations of the present disclosure. The passage 110a allows aerosol to pass through. When the aerosol flows in the passage 110a, the temperature of the aerosol is gradually reduced.

In an implementation, a material of the cooling member 110 includes a food-grade material. When aerosol flows through the passage 110a of the cooling member 110, the cooling member 110 produces less or even no toxic substance when being heated. For example, the material of the cooling member 110 may include, but is not limited to, white cardboard paper or kraft paper.

Optionally, when the cooling member 110 is made of white cardboard paper, the white cardboard paper is white cardboard paper of 50 g/m²-200 g/m², so that the cooling member 110 has a good cooling performance and a good strength, and is not easily deformed. When the cooling member 110 is made of kraft paper, the cooling member 110 is kraft paper of 50 g/m²-200 g/m², so that the cooling member 110 has a good cooling performance and a good strength, and is not easily deformed.

It can be understood that in an implementation, the material of the cooling member 110 may also include PLA, silicone, or an injection-molded part, as long as the cooling member 110 is capable of lowering a temperature.

Reference can be made to FIG. 26, which is a schematic structural view of a cooling member provided in an implementation. In this implementation, the cooling member 110 includes multiple convolute-wound cooling layers 1111. When the cooling member 110 includes convolute-wound cooling layers 1111, the number of the cooling layers 1111 may be 3 to 6, such as, 3, 4, 5, or 6. The cooling member 110 includes multiple convolute-wound cooling layers 1111, so that the cooling member 110 has good strength and is not easily deformed.

It may be noted that in the so-called convolute wound means that, seam L01 of the cooling layer 1111 is parallel or substantially parallel to centerline L02 of the cooling member 110.

Reference can be made to FIG. 27, which is a schematic structural view of a cooling member provided in another implementation of the present disclosure. In this implementation, the cooling member 110 includes multiple spiral-wound cooling layers 1111.

In this implementation, the cooling member 110 includes multiple spiral-wound cooling layers 1111. When the cooling member 110 includes multiple spiral-wound cooling layers 1111, the number of the cooling layers 1111 may be 2 to 4, such as, 2, 3, or 4. The cooling member 110 includes multiple spiral-wound cooling layers 1111, so that the cooling member 110 has good strength and is not easily deformed.

It may be noted that the so-called spiral wound means that, extension line L01 at a seam between adjacent cooling layers 1111 is inclined relative to centerline L02 of the cooling member 110, for example, an angle of inclination of 135°±15° exists between extension line L01 and centerline L02. The angle of inclination of 135°±15° may also be regarded as 45°±15°. In other words, an angle between extension line L01 and centerline L2 is 45°±15°.

Compared with the cooling member 110 including multiple convolute-wound cooling layers 1111, for the cooling member 110 including multiple spiral-wound cooling layers 1111, the multiple spiral-wound cooling layers 1111 are fixed to each other by means of adhesive glue. Therefore, the multiple cooling layers 1111 can be firmly fixed to each other, so that the cooling member 110 has better stability, better strength, and better roundness (which means that an opening of the cooling member 110 is more rounded).

The manner in which the closing member 140 is fixed to the first end 20a may be, but is not limited to, adhesion by a glue or fixing by an adhesive tape. In this implementation, the closing member 140 is fixed to the first end 20a by means of a glue. In an implementation, the glue is a food-grade glue. When aerosol passes through the cooling member 110, the glue produces less or even no toxic substance when being heated. The food-grade glue may be, but is not limited to, a glutinous rice glue, a lap glue, a straw glue, a white emulsion glue, etc.

In this implementation, for example, the closing member 140 is fixed to an end surface of the first end 111 away from the second end 112. It can be understood that in another implementation, the closing member 140 may also be fixed to a peripheral side surface of the first end 111. Alternatively, in yet another implementation, the closing member 140 may be fixed to the end surface of the first end 111 away from the second end 112, and is fixed to the peripheral side surface of the first end 111.

In an implementation, a material of the first closing member 140 may include, but is not limited to, silk tissue paper, air-permeable paper, or butter paper. The silk tissue paper, the air-permeable paper, and the butter paper all have good air permeability, which is beneficial for the aerosol to pass through. When the first closing member 140 is made of silk tissue paper, the first closing member 140 is made of silk tissue paper of 1 g/m²-50 g/m². When the first closing member 140 is made of air-permeable paper, the first closing member 140 is made of air-permeable paper of 1 g/m²-50 g/m². When the first closing member 140 is made of butter paper, the first closing member 140 is made of butter paper of 45 g/m²-105 g/m².

In addition, in order to reduce resistance to draw when the aerosol is drawn, the closing member 140 defines at least one through hole 141 in communication with the passage 110a.

A material of the filter member 40 may include, but is not limited to, PLA fibers. The filter member 40 can filter the aerosol, thereby improving the taste of the heat-not-burn cartridge 1. In an implementation, the filter member 40 is disposed in a compressed state in the first tube 20, to prevent the filter member 40 from falling out of the first tube 20. That the filter member 40 is disposed in the compressed state in the first tube 20 means the following. The filter member 40 has a first volume in a natural state, and has a second volume when being disposed in the first tube 20, where the first volume is larger than the second volume. That the filter member 40 is in the natural state means that the filter member 40 is neither under pressure nor under tension. When the heat-not-burn cartridge 1 is assembled, the filter member 40 needs to be squeezed to cause the filter member 40 to be compressed, so that the filter member 40 can be disposed in the first tube 20. In addition, when the filter member 40 is removed from the first tube 20, a radial dimension of the filter member 40 may be larger than a radial dimension of an inner diameter of the first tube 20.

Reference can be made to FIG. 28 and FIG. 29A to FIG. 29D, where FIG. 28 is a schematic structural view of a closing member in FIG. 22, and FIG. 29A to FIG. 29D are respectively schematic structural views of closing members in another implementation. The at least one through hole 141 is implemented as six to thirteen through holes 141. A diameter of each through hole 141 ranges from 0.6 mm to 1.0 mm. A distance between any two adjacent through holes 141 ranges from 0.8 to 1.0 mm.

The closing member 140 may be formed by die stamping, cutter punching, or laser cutting. The through hole 141 may be defined by die stamping, cutter punching, or laser cutting. A manufacturing process of the closing member 140 may be the same as or different from a manufacturing process of the through hole 141.

The through hole 141 may be circular, elliptical, polygonal, trapezoidal, trapezoidal-like, or the like, which is not limited herein.

When the through hole 141 is circular, the diameter of the through hole 141 is the diameter of the circle. When the through hole 141 is non-circular, the diameter of the through hole 141 refers to a distance between two points of the through hole 141 with the largest dimension. When the through hole 141 is non-circular, the distance between two points of the through hole 141 with the largest dimension is the equivalent diameter of the through hole 141.

With the above structural design of the at least one through hole 141 in the closing member 140 provided in implementations of the present disclosure, on the one hand, the aerosol can uniformly pass through, and the resistance to draw when the aerosol is drawn can be reduced; and on the other hand, the structural strength of the closing member 140 can also be maintained, so that the closing member 140 is not easily broken.

Reference can be made to FIG. 30, which is a schematic view of a distance between a through hole at an outermost peripheral side of through holes in a closing member in FIG. 25 and an outer peripheral edge of the closing member in FIG. 25. A distance between the through hole 141 at an outermost peripheral side of through holes 141 in the closing member 140 and an outer peripheral edge of the closing member 140 ranges from 0.7 mm to 0.8 mm. In FIG. 30, the distance between the through hole 141 at the outermost peripheral side in the closing member 140 and the outer peripheral edge of the closing member 140 is marked as d1, which satisfies 0.7 mm≤d1≤0.8 mm. In FIG. 8, L1 is a tangent of the through hole 141 at point A, and L2 is a tangent of the closing member 140 at point B, where connection line AB passes through the center of the closing member 140.

When the closing member 140 is fixed to the cooling member 110, a certain adhesive width, such as, 0.3 mm to 0.4 mm, needs to be set aside. In addition, when the through hole 141 is machined, a machining tolerance may exist. In order to prevent the through hole 141 from being machined to the edge of the closing member 140 or prevent the through hole 141 from being machined to the position where the closing member 140 is adhered to the glue, a distance of about 0.4 mm may be set aside. It can be seen therefrom that by setting the distance between the through hole 141 located at the outermost peripheral side of through holes 141 and the outer peripheral edge of the closing member 140 ranges from 0.7 mm to 0.8 mm, on the one hand, the requirement that the closing member 140 is adhered to the cooling member 110 can be met, and on the other hand, the requirement of the machining tolerance during machining of the through hole 141 can be met.

Reference can be made to FIG. 31, where FIG. 31 is a schematic cross-sectional view of a heat-not-burn cartridge provided in another implementation taken along line VI-VI, and FIG. 32 is an enlarged schematic view at circle G in FIG. 31. The filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, and the smoke generating member 30 and the sealing member 60 at the first end 20a define a gap G0 therebetween.

The filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, and the gap G0 exists between the smoke generating member 30 and an end surface of the first end 20a. Since the sealing member 60 is disposed at the first end 20a, the gap G0 exists between the smoke generating member 30 and the sealing member 60 at the first end 20a. Therefore, when at least one of the smoke generating member 30 or the cooling assembly 10 moves, there is relatively sufficient movable space in the first tube 20. When the heating needle of the smoking set is inserted into the smoke generating member 30, at least one of the smoke generating member 30 or the cooling assembly 10 moves, so that a density of part of the smoke generating member 30 inserted by the heating needle is less changed or is not changed, thereby not affecting the taste of drawing the heat-not-burn cartridge 1.

During heating of the heat-not-burn cartridge 1 by the smoking set, although the smoke generating member 30 in the heat-not-burn cartridge 1 is disposed downwards relative to the filter member 40, when the heating needle of the smoking set is inserted into the smoke generating, the at least one of the smoke generating member 30 or the cooling assembly 10 may also be moved due to sufficient movable space in the first tube 20. Therefore, the density of the part of the smoke generating member 30 inserted by the heating needle changes little or does not change, thereby not affecting the taste of drawing the heat-not-burn cartridge 1.

Further referring to FIG. 32, the heat-not-burn cartridge 1 further includes the sealing member 60 disposed at the first end 20a of the first tube 20. The filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, and a height h1 of the gap G0 between the smoke generating member 30 and the sealing member 60 is 1.5 mm±10%.

The height h1 of the gap G0 is 1.5 mm±10%, that is, the height h1 of the gap G0 ranges from 1.35 mm to 1.65 mm. It may be noted that in implementations/embodiments of the present disclosure, when a numeric range from A to B is involved, it is indicated that an endpoint value A is included and an endpoint value B is included, if not specifically indicated. The gap may range from 1.35 mm to 1.65 mm. For example, the gap may be, but is not limited to, 1.35 mm, 1.40 mm, 1.45 mm, 1.50 mm, 1.55 mm, 1.60 mm, or 1.65 mm.

When the filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, and the gap between the smoke generating member 30 and the sealing member 60 is less than 1.35 mm, the gap between the smoke generating member 30 and the sealing member 60 is relatively small, so that when the smoke generating member 30 in the heat-not-burn cartridge 1 is inserted by the heating needle, the heating needle may cause a relatively large change in the density of the part of the smoke generating member 30 inserted by the heating needle (the density of the part of the smoke generating member 30 inserted by the heating needle increases), thereby affecting the taste of drawing the heat-not-burn cartridge 1.

When the filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, and the gap between the smoke generating member 30 and the sealing member 60 is greater than 1.65 mm, the gap between the smoke generating member 30 and the sealing member 60 is relatively large, so that when the smoke generating member 30 in the heat-not-burn cartridge 1 is inserted by the heating needle, the heating needle may cause a relatively small change or even no change in the density of the part of the smoke generating member 30 inserted by the heating needle. However, the smoke generating member 30 may not be in good contact with the heating needle in the smoking set, thereby affecting the taste of drawing the heat-not-burn cartridge 1.

It can be understood that in this implementation, when the filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, the height of the gap between the smoke generating member 30 and the sealing member 60 is 1.5 mm±10%. In other implementations, when the filter member 40 of the heat-not-burn cartridge 1 is disposed downwards relative to the cooling assembly 10, it is sufficient that a gap exists between the smoke generating member 30 and the sealing member 60, so that a great change in the density of the part of the smoke generating member 30 inserted by the heating needle when the heating non-burning cartridge 1 is inserted by the heating needle in the smoking set can be reduced to some extent, thereby reducing or even avoiding an impact caused by the density change on the taste of drawing the heat-not-burn cartridge 1.

Reference can be further made to FIG. 33, which is an enlarged schematic view at circle P in FIG. 31. Part of the filter member 40 is accommodated in the passage 110a.

Since at one end of the cooling member 110 away from the closing member 140, the cooling member 110 is open and no closing member 140 is disposed, the part of the filter member 40 is accommodated in the passage 110a from the end of the cooling member 110 away from the closing member 140. The part of the filter member 40 is accommodated in the passage 110a from the end of cooling member 110 away from the closing member 140, so that the aerosol output from the cooling member 110 relatively easily enters the filter member 40. Therefore, the filter member 40 can absorb and filter out relatively large particles in the aerosol, so that the heat-not-burn cartridge 1 has a good smoking taste when being drawn.

Referring to FIG. 33, one end of the filter member 40 away from the cooling assembly 10 is recessed in the accommodating space 210. The end of the filter member 40 away from the cooling assembly 10 is recessed in the accommodating space 210, so that when the user draws the heat-not-burn cartridge 1, less or even no filter member 40 enters an oral cavity of the user, thereby allowing the heat-not-burn cartridge 1 to be relatively sanitary when being drawn.

In other implementations, one end of the filter member 40 away from the cooling assembly 10 is flush with an end surface of the second end 20b away from the first end 20a. In other words, the end of the filter member 40 away from the cooling assembly 10 is flush with the end surface of the first tube 20. When the end of the filter member 40 away from the cooling assembly 10 is flush with the end surface of the second end 20b away from the first end 20a, the heat-not-burn cartridge 1 can have a good appearance. In addition, when the user draws the heat-not-burn cartridge 1, less or even no filter member 40 enters the oral cavity of the user, so that the heat-not-burn cartridge 1 is relatively sanitary when being drawn.

Referring to FIG. 22 or FIG. 30 again, the smoke generating member 30 includes multiple smoke generating particles, multiple smoke generating sheets, or multiple smoke generating particles and multiple smoke generating sheets. The smoke generating member 30 has a length ranging from 13 mm to 16.5 mm. The cooling assembly 10 has a length ranging from 16 mm to 23 mm. The filter member 40 has a length ranging from 8 mm to 10 mm.

With the above dimensions of the smoke generating member 30, the cooling assembly 10, and the filter member 40 in the heat-not-burn cartridge 1 provided in implementations of the present disclosure, on the one hand, the smoke generating member 30 can produce more aerosol, and on the other hand, the cooling assembly 10 can have a good cooling effect on the aerosol produced by the smoke generating member 30. In addition, the filter member 40 has a good filtering effect on the aerosol, so that the heat-not-burn cartridge 1 provides a good draw experience.

Reference can be made to FIG. 34, FIG. 35, FIG. 36, and FIG. 37 together, where FIG. 34 is a schematic perspective structural view of a heat-not-burn cartridge provided in an implementation of the present disclosure, FIG. 35 is an exploded perspective view of the heat-not-burn cartridge in FIG. 34, FIG. 36 is a cross-sectional view in FIG. 34 taken along line VII-VII, and FIG. 37 is an enlarged schematic view at circle Q in FIG. 36. In this implementation, the heat-not-burn cartridge 1 further includes a second tube 50 sleeved on a peripheral side surface of the first tube 20.

Specifically, when the heat-not-burn cartridge 1 is manufactured, due to various reasons, defects may exist on the appearance of the first tube 20. For example, the smoke generating member 30 may cause the first tube 20 to be stained, or cause the first tube 20 to be scratched.

The second tube 50 is sleeved on the peripheral side surface of the first tube 20 and can shield the first tube 20, so that the heat-not-burn cartridge 1 is more beautiful. In an implementation, a material of the second tube 50 includes tipping paper. In an implementation, the tipping paper is tipping paper of 32 g/m²-40 g/m². In an implementation, the heat-not-burn cartridge 1 satisfies at least one of the following. A material of the first tube 20 includes white cardboard paper of 50 g/m²-200 g/m² or kraft paper of 50 g/m²-200 g/m². The first tube 20 has a length ranging from 42 mm to 46 mm, and when the heat-not-burn cartridge 1 further includes a second tube 150, the second tube 150 has a length ranging from 42 mm to 46 mm. The cooling member 110 has an outer diameter ranging from 6.0 mm to 6.6 mm, the first tube 20 has an inner diameter ranging from 6.4 mm to 6.65 mm, the first tube 20 has an outer diameter ranging from 6.9 mm to 7.1 mm, the filter member 40 has an outer diameter ranging from 6.5 mm to 7.0 mm, and the filter member 40 is disposed in a compressed state in the first tube 20. When the heat-not-burn cartridge 1 further includes the second tube 150, the outer diameter of the cooling member 110 ranges from 6.0 mm to 6.6 mm, the inner diameter of the first tube 20 ranges from 6.4 mm to 6.65 mm, the outer diameter of the first tube 20 ranges from 6.9 mm to 7.1 mm, the outer diameter of the filter member 40 ranges from 6.5 mm to 7.0 mm, the filter member 40 is disposed in the compressed state in the first tube 20, and the second tube 150 has an outer diameter ranging from 7.15 mm to 7.3 mm.

It can be understood that in the schematic diagram of this implementation, that the heat-not-burn cartridge 1 further includes the second tube 50 is combined with the implementation that the end of the filter member 40 away from the cooling assembly 10 is flush with the end surface of the first tube 20, for illustration. It can be understood that no limitation is made to the heat-not-burn cartridge 1 provided in implementations of the present disclosure. That the heat-not-burn cartridge 1 further includes the second tube 50 may be combined in any of the preceding implementations. When the end of the filter member 40 away from the cooling assembly 10 is flush with the end surface of the first tube 20, the heat-not-burn cartridge 1 can have a good appearance. In addition, when the user draws the heat-not-burn cartridge 1, less or even no filter member 40 enters the oral cavity of the user, so that the heat-not-burn cartridge 1 is relatively sanitary when being drawn.

In summary, in a possible implementation, the heat-not-burn cartridge 1 satisfies at least one of the following. A material of the first tube 20 includes white cardboard paper of 50 g/m²-200 g/m² or kraft paper of 50 g/m²-200 g/m². A material of the cooling member 110 includes at least one of white cardboard paper of 50 g/m²-200 g/m², kraft paper of 50 g/m²-200 g/m², PLA, silicone, or an injection-molded part.
