Description

Technical Field

[0001] This utility model relates to the field of novel heated tobacco technology, specifically a tobacco cartridge and smoking device for rapid cooling. Background Technology

[0002] Heated tobacco products (HNB) technology, as a potential new tobacco technology route to reduce the harms of smoking, has rapidly emerged and flourished globally. HNB systems can be categorized into resistance heating, electromagnetic heating, infrared heating, and laser heating types based on their heating principles. Regardless of the heating method used, the core components of the system can be summarized as the device and the cartridge. Generally, the device includes the cartridge compartment, heating element, temperature control system, and power supply system, which provide heat energy to the cartridge. The cartridge includes an aerosol generating matrix, cooling components, filter, and tube. The aerosol generating matrix undergoes a series of physicochemical reactions under heating to produce an inhalable aerosol. Commercially available HNB devices commonly suffer from excessively high aerosol temperatures. Because the cartridges used are generally shorter than traditional cigarettes, the contact time between the aerosol and the internal components of the cartridge is short before it enters the user's mouth, making it difficult to cool it sufficiently. Excessively high aerosol temperatures not only affect the user's sensory experience but may also pose potential health risks to the user's mouth and respiratory tract.

[0003] Existing aerosol cooling technologies mainly focus on improving the structure of the cartridge, such as using multi-stage cooling structures, phase change heat-absorbing materials, or microporous heat dissipation methods to accelerate heat dissipation and reduce the aerosol temperature. However, these cooling measures based on cartridge structures have certain limitations, including complex structures, high manufacturing costs, expensive materials, and poor cooling effects.

[0004] In view of this, a new aerosol cooling technology is being developed, starting from the structure of the HNB system, to achieve effective control of aerosol temperature, which can improve user experience and reduce product costs. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a cartridge compartment for rapid cooling, comprising a cartridge compartment body for receiving cartridges, a receiving cavity with one end open, and a cooling component disposed at the opening of the cartridge compartment body, wherein the cartridge passes through the cooling component and is housed in the receiving cavity, and the cooling section of the cartridge is close to or abuts against the cooling component.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 As shown, the cartridge compartment of the smoking device includes a cartridge compartment body 1 and a cooling component 2. The cartridge compartment body 1 has a recessed receiving cavity with an open end and its cavity wall 11. The receiving cavity of the cartridge compartment body 1 is used to receive the cartridge 3. Functionally, the cartridge 3 includes three parts: a smoke-generating section, a cooling section 31, and a filter section 32. After the smoke-generating section is heated, the airflow passes through the cooling section and is cooled before being absorbed by the user through the filter section. The cooling component 2 is provided at the opening of the cartridge compartment body 1. The cooling component 2 is configured as a hollow ring. The cartridge 3 passes through the cooling component 2 and is housed in the receiving cavity. The cooling section 31 of the cartridge 3 (in other embodiments, it may also be other sections of the cartridge 3, configured according to different cartridge length models) is close to or abuts against the cooling component 2. The cooling component 2 is configured to be physically connected or fixed to the cartridge compartment body 1.

[0022] The cooling component 2 is designed in a ring shape, with its internal hollow area configured to be approximately circular. Near the center, where it approaches or abuts the cartridge 3, it is configured with a smooth surface, such as an arc surface or a flat surface. The minimum inner diameter of the cooling component 2 is adjusted according to the outer diameter of the cartridge 3, such as the common 6.5mm-8mm.

[0023] To achieve a better cooling effect, i.e., a large cooling amount and a fast cooling rate, materials with high thermal conductivity and high specific heat capacity are preferred for fabrication. Cooling component 2 is made of a thermally conductive material, such as metals, ceramics, or silicone with a heat-transfer formula, forming a metal ring, ceramic ring, or silicone ring. For example, metals such as copper, aluminum, molybdenum, and tungsten, as well as alloys composed of these materials, have good thermal conductivity, generally greater than 150 W / m·K, and can rapidly conduct heat energy. However, in electromagnetic induction heating applications, the use of magnetic metal materials should be avoided. For example, certain special ceramics have excellent thermal conductivity. For instance, 99% beryllium oxide ceramics have a high thermal conductivity, reaching 280 W / m·K, while alumina ceramics have a thermal conductivity of approximately 37 W / m·K. Furthermore, aluminum nitride ceramics and silicon carbide ceramics also exhibit excellent thermal conductivity, reaching approximately 200 W / m·K and 270 W / m·K, respectively. For example, silicone: Although the thermal conductivity of its base material is between 0.8 and 5.0 W / m·K, its thermal conductivity can usually be significantly improved by optimizing factors such as the composition of the silicone, the type and content of fillers, the type and amount of hardeners, the processing technology, and the addition of thermally conductive fillers. For example, carbon materials: Carbon materials have good thermal conductivity, with a thermal conductivity typically in the range of 500 to 1000 W / (m·K), and also have a low coefficient of thermal expansion.

[0024] The cartridge 3 passes through the cooling element 2 and is housed within the receiving cavity. The cooling section 31 of the cartridge 3 is close to or abuts against the cooling element 2, with direct contact or close proximity to facilitate rapid heat conduction and improve heat transfer efficiency. This is a direct and / or indirect heat conduction method for cooling. The cooling element 2 is kept as far away as possible from the filter section 32 of the cartridge 3, especially from the end of the filter section 32, maintaining a certain distance from the mouth to achieve a better cooling effect and prevent burns. In this embodiment, the axial distance between the cooling element 2 and the end of the filter 32 is set between 15-45 mm to reduce the occurrence of such usage problems.

[0025] In this embodiment, the inner surface of the cooling component 2 is set as a smooth cylindrical surface, and the inner diameter is slightly larger than the outer diameter of the cartridge 3, such as 9mm. When receiving a 7.5mm cartridge, there is a gap so that there is incomplete contact or no contact at all. The remaining heat of the cooling section of the cartridge 3 is conducted to the cooling component 2 and then conducted out, ultimately achieving a reduction in the temperature of the aerosol.

[0026] In this embodiment, see Figure 1 The outer shell 4 of the smoking device is tightly connected to the cartridge body 1 and the cooling component 2. The material is metal or ceramic, which is conducive to the heat of the concentrated part to the surrounding heat dissipation and has an exquisite appearance.

[0027] Example 2

[0028] See Figure 2 Building upon Embodiment 1, the cooling component 2 features a raised positioning structure 21 at its point of contact with the tobacco cartridge. This structure, such as ribs, protrusions, or grooves, serves a similar positioning and contact function, allowing for localized contact with the cooling section 31 of the tobacco cartridge 3. Appropriate resistance also enhances the user's insertion and removal feel and prevents the tobacco cartridge 3 from shifting within the receiving cavity. Heat is conducted to the outside via the positioning structure 21, effectively reducing the temperature of the filter section 32 that contacts the mouth.

[0029] Example 3

[0030] Unlike the previous embodiments, the cooling component 2 is configured as multiple protrusions at the opening of the cartridge body 1, distributed along the peripheral wall of the receiving cavity. The number includes multiple protrusions, such as four evenly distributed on the peripheral wall. The material used is high-performance copper, which provides good heat conduction when in close contact with the cartridge. The protrusions are connected to the cartridge body 1 using methods such as bonding, ultrasonic welding, mechanical snap-fit, or threaded connection, depending on the manufacturing process. The inner side of the protrusion is designed with a contoured arc segment to facilitate tight contact with the cartridge and transfer excess heat.

[0031] Furthermore, the cooling component 2 also includes an auxiliary positioning part for fixing each protrusion, such as a metal ring similar to that in Embodiment 1, which is injection molded into the body 1 of the cigarette cartridge. The protrusion and the metal ring are fixedly connected. The advantage of this is that each protrusion only needs to be positioned by the metal ring during processing, and the protrusion will be in the preset receiving cavity position.
